[0002] Release paper, also known as silicone paper or anti-stick paper, primarily serves to isolate sticky substances, such as adhesive tape. It is generally peeled off and discarded during use. In the food packaging industry, to ensure food hygiene, a sealable food packaging bag has been designed. After the food is placed in the bag, the release paper is peeled off, revealing the adhesive strip for bonding. Therefore, a release paper adhesive application device is needed to implement the adhesive application process for food packaging bags. Utility Model Content

A conveying mechanism is provided within the conveying space and is used to convey raw paper along a first direction; The glue application mechanism includes a linear driver disposed in the conveying space and a glue gun assembly disposed on the linear driver. The linear driver drives the glue gun assembly to move along a second direction. The angle between the second direction and the first direction is an acute angle. The component velocity of the glue gun assembly along the first direction is equal to the linear velocity of the raw material paper being conveyed.

[0005] Preferably, the linear driver is a linear motor.

[0006] Preferably, the linear actuator is a dual-movement linear motor, in which the two movers of the dual-movement linear motor drive a set of glue gun assemblies to move in opposite directions.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] A release paper coating device, combined with Figure 1 - Figure 5 As shown, it includes: Frame 1 is equipped with a conveyor space; A conveying mechanism is provided within the conveying space and is used to convey raw paper along a first direction; The glue application mechanism includes a linear driver 31 disposed within a conveying space and a glue gun assembly 32 disposed on the linear driver 31. The linear driver 31 drives the glue gun assembly 32 to move along a second direction, the angle between the second direction and the first direction being an acute angle. The component velocity of the glue gun assembly 32 along the first direction is equal to the linear velocity of the raw material paper being conveyed. This application, by setting up a conveying mechanism and a glue application mechanism, and by having the linear driver 31 drive the glue gun assembly 32 to move along the second direction, and ensuring that the component velocity of the glue gun assembly 32 along the first direction is equal to the linear velocity of the raw material paper being conveyed, achieves a combined motion of the two assemblies, resulting in the glue gun assembly 32 moving laterally linearly relative to the raw material paper. This allows for the application of a transverse strip of glue onto the raw material paper for attaching release paper.

[0019] Specifically, the raw paper enters through the inlet of the conveying space and exits through the outlet after being coated with glue. The first direction is the conveying direction of the raw paper from front to back. The second direction forms an acute angle with the first direction, that is, the second direction is an inclined direction from front to back. The third direction is along the width of the raw paper, that is, the left-right direction.

[0020] Preferably, the linear driver 31 is a linear motor, which has a fast response and an easily adjustable driving speed to match different conveying speeds of the raw paper.

[0021] Preferably, the linear actuator 31 employs a dual-movement linear motor, with each of the two movers driving a set of glue gun assemblies 32 to move in opposite directions. The dual-movement linear motors are symmetrically arranged, with the two sets of glue gun assemblies 32 located on either side of the motor body. When one glue gun assembly 32 moves obliquely from front to back along a second direction to apply glue, the other glue gun assembly 32 can continue applying glue after one side has finished. For example, the other glue gun assembly 32 can move obliquely from back to front along the second direction to apply glue. The alternating application of glue by the two glue gun assemblies 32 can meet the high conveying speed requirements of the raw material paper glue.

[0022] Preferably, the angle between the second direction and the first direction is 45°, so that the component velocity of the glue gun assembly 32 in the first direction is equal to the component velocity in the third direction, which facilitates speed control.

[0023] Preferably, the two ends of the linear actuator 31 are mounted on the frame 1 via guide components 33, which guide the movement of the linear actuator 31 in a third direction perpendicular to the first direction in the horizontal plane. The frame 1 is provided with an adjustment component, which drives the linear actuator 31 to move in the third direction. By adjusting the linear actuator to move in the third direction, and with the guide component 33 providing guidance and limiting, the position of the linear actuator 31 in the third direction can be adjusted, thereby meeting the requirements for coating raw paper of different widths.

[0024] Specifically, the guide assembly 33 uses two sets of linear guides. The tracks of the linear guides are fixed to the frame 1 by screws. The sliders of the linear guides are connected to the linear driver 31 through a connecting plate. The sliders slide along the tracks to guide the linear driver 31.

[0025] Preferably, the adjustment assembly includes a lead screw 11 rotatably connected to the frame 1 and a lead screw nut connected to the linear actuator 31. Rotating the lead screw 11 drives the lead screw nut to move in a third direction, thereby driving the linear actuator 31 to move. After unlocking the lead screw 11, the position of the linear actuator 31 can be adjusted by rotating the handle to rotate the lead screw 11. After adjustment, the lead screw 11 is locked to prevent position changes.

[0026] Preferably, the conveying mechanism includes a first conveying roller 21 and a pallet 22 rotatably mounted on the frame 1. The raw paper slides on the pallet 22 after passing over the first conveying roller 21 for conveying. The raw paper is located between the pallet 22 and the glue gun assembly 32.

[0027] Preferably, the conveying mechanism further includes a transition plate 23, the support plate 22 is higher than the first conveying roller 21, the transition plate 23 is fixedly connected to the support plate 22 on one side and extends downward at an angle to the outer peripheral surface of the first conveying roller 21 on the other side, for guiding the raw material paper onto the support plate 22; a gap is left between the transition plate 23 and the outer peripheral surface of the first conveying roller 21 to ensure the smooth rotation of the first conveying roller 21.

[0028] Preferably, the conveying mechanism further includes a second conveying roller 24, which is located on the side of the first conveying roller 21 away from the pallet 22. The raw material paper passes under the second conveying roller 24 and then passes over the first conveying roller 21, so that the raw material paper can better fit the first conveying roller 21 and be conveyed forward under the action of friction.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
