Description

Technical Field

[0001] The utility model relates to a bag making machine, in particular to a release paper feeding device applied to a bag making machine. Background Art

[0002] A bag making machine is a device for producing bags. As Figure 3 shown, a release paper B needs to be pasted on the upper edge of the bag mouth of some bags A for sealing. Therefore, a release paper feeding device needs to be installed on the bag making machine for making such bags. Currently, the release paper feeding device generally includes a traction mechanism, a glue spraying mechanism and a first buffer mechanism. The traction mechanism is used to pull out the release paper from the release paper roll, the glue spraying mechanism is used to spray glue on the release paper, and the first buffer mechanism is used to store the release paper pulled out by the traction mechanism. However, for the existing release paper feeding device, the release paper coming out of the release paper roll directly enters the traction mechanism without any buffer mechanism in between. In this case, if the machine stops or the traction mechanism stops for other reasons, the release paper roll still rotates due to inertia, resulting in the release paper coming loose; if the traction mechanism is started, due to sudden pulling, the traction mechanism may break the release paper. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the utility model innovatively provides a release paper feeding device that prevents the release paper from being broken.

[0004] This release paper feeding device includes a bracket, a traction mechanism and a glue spraying mechanism. The bracket has a placement position for placing the release paper roll. The traction mechanism includes a traction roller set. The glue spraying mechanism includes a glue spraying head. It is characterized in that: a first buffer mechanism is provided between the placement position of the release paper roll and the traction mechanism. The first buffer mechanism includes a first swing rod, a first floating guide wheel and a first fixed guide wheel. The first floating guide wheel is installed on the first swing rod. One end of the first swing rod is hinged to the bracket. The first fixed guide wheel is installed on the bracket.

[0005] The first floating guide wheel is located below the first fixed guide wheel.

[0006] The first fixed guide wheel is installed on a guide wheel mounting plate. The guide wheel mounting plate is connected to the bracket. A first limiting rod is connected to the first swing rod. The first limiting rod is located directly below the guide wheel mounting plate. The guide wheel mounting plate can limit the upward movement of the first limiting rod.

[0007] A second buffer mechanism is provided between the traction mechanism and the glue spraying mechanism. The second buffer mechanism includes a second swing rod, a second floating guide wheel and a second fixed guide wheel. The second floating guide wheel is installed on the second swing rod. One end of the second swing rod is hinged to the bracket.

[0008] The second floating guide wheel is located below the second fixed guide wheel. A second limit rod is connected to the bracket. The second limit rod is located below the second swing rod, and the second limit rod can limit the downward movement of the second swing rod.

[0009] The glue spraying mechanism includes a glue spraying head support. The glue spraying head is installed on the glue spraying head support. A vertical guide rail is installed on the bracket. The glue spraying head support is slidably arranged on the guide rail. An adjusting nut is connected to the glue spraying head support. A rotatable adjusting screw is installed on the bracket, and the adjusting screw is in threaded connection with the adjusting nut.

[0010] According to a release paper feeding device provided by the present invention, by arranging a buffer mechanism between the release paper roll and the traction mechanism, a buffer space is provided for the release paper coming out of the release paper roll, thereby ensuring the stable feeding of the release paper roll. Description of the Drawings

[0011] Figure 1 is the front view of the present invention;

[0012] Figure 2 is the rear view of the present invention;

[0013] Figure 3 is a schematic diagram of the bag. Detailed Embodiments

[0014] As Figure 1 shown, such a release paper feeding device includes a bracket 1, a traction mechanism 4 and a glue spraying mechanism 6. The bracket 1 has a placement position 10 for placing the release paper roll 2 (the feeding retaining ring with the release paper roll 2 is placed at this position). The release paper on the release paper roll 2 moves forward under the traction of the traction mechanism 4. There is also a fitting traction roller group on the bag making machine. The fitting traction roller group pulls the release paper B forward and fits the release paper B to the upper edge of the paper bag A. Before fitting, the glue spraying mechanism 6 sprays glue on the release paper, so that the release paper can be adhered to the paper bag.

[0015] As Figure 1As shown in the figure, the traction mechanism 4 includes a traction roller set 41 and a traction motor 40. Driven by the traction motor 40, the traction roller set 41 pulls the paper sprayed with glue forward. The glue spraying mechanism 6 includes a glue spraying head 60, and the glue spraying head 60 sprays the glue onto the release paper. To address the deficiencies of the prior art, a first buffer mechanism 3 is provided between the placement position 10 of the release paper roll 2 and the traction mechanism 4 (in terms of the feeding path of the release paper). The first buffer mechanism 3 includes a first swing rod 32, a first floating guide wheel 30, and a first fixed guide wheel 31. The first floating guide wheel 30 is installed on the first swing rod 32. One end of the first swing rod 32 is hinged to the bracket 1, and the first fixed guide wheel 31 is installed on the bracket 1. The release paper coming out of the release paper roll 2 sequentially winds around the first fixed guide wheel 31 and the first floating guide wheel 30 (as shown in Figure 1 the winding method shown). When the traction mechanism 4 is traction normally, due to the stable pulling force, the first swing rod 32 is in a certain position; when the traction mechanism 4 suddenly stops and no longer pulls, the release paper roll 2 continues to rotate due to inertia and continues to release the release paper. Because the pulling force does not exist, the first swing rod 32 gradually swings downward due to its own weight, and stores the release paper continuously coming out of the release paper roll 2. In this way, the release paper will not become loose when the machine stops; when starting the machine, the traction mechanism 4 starts to pull, pulling the first swing rod 32 to gradually swing upward, so that the release paper is gradually discharged, and the release paper will not be broken.

[0016] As Figure 1 shown, the first floating guide wheel 30 is located below the first fixed guide wheel 31, and the release paper roll 2 is located above the first fixed guide wheel 31. The first fixed guide wheel 31 is installed on the guide wheel mounting plate 33, and the guide wheel mounting plate 33 is connected to the bracket 1. As Figure 2 shown, a first limit rod 34 is connected to the first swing rod 32. The first limit rod 34 is located directly below the guide wheel mounting plate 33, and the guide wheel mounting plate 33 can limit the upward movement of the first limit rod 34. In this way, the first swing rod 32 has a maximum swing upper limit, preventing the first fixed guide wheel 31 and the first floating guide wheel 30 from getting too close.

[0017] To buffer the release paper between the traction mechanism 4 and the glue spraying mechanism 6, a second buffer mechanism 5 is provided between the traction mechanism 4 and the glue spraying mechanism 6. The second buffer mechanism 5 includes a second swing rod 50, a second floating guide wheel 51, and a second fixed guide wheel 52. The second floating guide wheel 51 is installed on the second swing rod 50, and one end of the second swing rod 50 is hinged to the bracket 1. The working principle of the second buffer mechanism 5 is the same as that of the first buffer mechanism 3. The release paper between the traction mechanism 4 and the glue spraying mechanism 6 is buffered by the swing of the second swing rod 50, preventing the release paper between the traction mechanism 4 and the glue spraying mechanism 6 from being pulled when the laminating traction roller set on the bag making machine starts, and at the same time providing a buffer space for the release paper between the traction mechanism 4 and the glue spraying mechanism 6.

[0018] Similarly, the second floating guide wheel 51 is located below the second fixed guide wheel 52. A second limiting rod 53 is connected to the bracket 1. The second limiting rod 53 is located below the second swing rod 50. The second limiting rod 53 can limit the downward movement of the second swing rod 50 to prevent the second swing rod 50 from sagging excessively.

[0019] Finally, it is worth mentioning that the glue spraying mechanism 6 includes a glue spraying head support 61, and the glue spraying head 60 is installed on the glue spraying head support 61. In order to adjust the vertical position of the glue spraying mechanism 6, a vertical guide rail 7 is installed on the bracket 1. The glue spraying head support 61 is slidably arranged on the guide rail 7. A regulating nut 62 is connected to the glue spraying head support 61, and a rotatable regulating screw 8 is installed on the bracket 1. The regulating screw 8 is threadedly connected to the regulating nut 62. During adjustment, by rotating the regulating screw 8, the glue spraying head support 61 can move up and down along the guide rail 7, thereby adjusting the height of the glue spraying head 60.
