The Method For Making The Winding Device Of Rolls Connecting Bag Making Machine

The method for making the winding device of rolls connecting bag making machine is as follows:

Background technology:

We know that in the past, the winding device of the winding bag machine used to be supported by a thick mandrel and then lined with paper or plastic pipes on the mandrel. When the winding bag did not need support, the support in the winding bag needed to be removed after the winding device was rolled up. Because the connection between the winding bags was very close during the winding operation. So it is very difficult to pull out the support.

Summary of the invention

In order to overcome the shortcomings of the prior art, the object of the present invention is to provide a coiling bag with simple structure, which can be supported by a coiling belt, and a coiling device of a coiling bag machine without a supporting coiling bag can be easily produced. The invention is a winding device of rolls connecting bag making machine, which is realized by the following technical scheme. Its features include a metal rod and two connecting heads. The metal rod is located in the middle of two connecting heads, and the two ends of the metal rod are connected with two connecting heads respectively. The two connecting heads are fixed on the bearings at both ends, and the connecting heads are disc-shaped, in which the connecting heads are also provided with upper and middle parts. The middle hole is threaded hole. In addition, the winding device of rolls connecting bag making machine includes a fixed head, which is an ellipse with a connecting hole in the middle. One end is connected with the middle hole of the connecting head and the other end is connected with the mandrel of the winding head. The diameter of the three holes is various, which can be adapted to different diameter of the winding mandrel. Further, the above-mentioned metal rods are two, which are respectively fixed in the upper and lower holes of the connecting head to realize the winding operation of the winding bag without support in the middle. The invention has the advantages of simple structure and convenient operation. By setting a mandrel with a certain void, the operation of pulling out the mandrel is simple and easy. At the same time, the invention also can realize the conversion of different mandrels by selecting fixed heads with different stepped hole diameters, thus saving the time and cost of replacing the device, and greatly improving the work efficiency and saving. Labor.

The metal rod 2 is located in the middle of the two connection heads 3, and the two ends are connected with the two connection heads 3 respectively. The two connection heads 3 are fixed on the bearing 1 at the two ends, and the connection heads 3 are disc-shaped. The connection heads 3 are also provided with three holes, the upper, middle and lower holes, and the middle holes are threaded holes. Two metal rods are fixed in the upper hole and the lower hole of the connecting head 3 respectively. At this time, two metal rods are used to roll up the coiling bag. When the coiling is finished, when the metal rod 2 is removed from the connecting head 3, because there is a gap between the two metal rods 2, it is very easy to pull out the two metal rods 2 from the coiling bag. The winding device of the winding bag machine also includes a fixed head 4. The fixed head 4 is an ellipse with a connecting hole in the middle. As an accessory, the diameter of the fixed head 4 has many kinds, which can meet the needs of the winding mandrel with different diameters. One end of the fixed head 4 is connected with the middle hole of the connecting head 3, and the other end is connected with the winding head 3 threads through the connecting hole in the middle. The mandrel is connected, and the two ends of the mandrel are sleeved on the fixed heads 4 on both sides to fix, and then the coiling bag is coiled. After completion, the mandrel for coiling is removed, and the coiling with support is completed. The invention has the advantages of simple structure and convenient operation, can realize the winding of the winding bag with support, and can easily accomplish the winding of the winding bag without support, greatly improving the production efficiency and reducing the cost. The present invention has been disclosed in better embodiments, but it is not intended to limit the invention. Any technical scheme obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the invention.
