Technical Field

[0001] This utility model relates to the technical field of gluing devices for packaging paper, specifically a small hand-push type gluing device for packaging paper. Background Technology

[0002] Packaging paper is a special type of paper used for packaging various goods and materials. It generally has high physical strength and a certain degree of water resistance. It features high strength, low moisture content, and water resistance. Some types also have special functions such as oil resistance and moisture resistance. According to their uses, they can be divided into categories such as ordinary packaging paper (such as kraft paper) and special packaging paper (such as rust-proof paper). The base paper and paperboard used for general packaging functions have corresponding special properties depending on the characteristics of the goods.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-6As shown, this utility model provides a technical solution: a small hand-push type gluing device for packaging paper, including a sliding housing 1. The bottom of the sliding housing 1 has an opening, and an operation placement plate 2 is inserted into the opening at the bottom of the sliding housing 1. The inner wall of the sliding housing 1 is slidably connected to the front and back of the operation placement plate 2. The operation placement plate 2 is supported by an external support frame. A push handle 3 is fixedly installed on the left side of the sliding housing 1. A packaging paperboard 4 is placed on the top surface of the operation placement plate 2. Openings for gluing are opened on both sides of the sliding housing 1. Side wall sliding blocks 6 are provided below the front and back panels of the sliding housing 1. Multiple small tension springs 5 ​​are fixedly installed on the top of the two side wall sliding blocks 6. The top of the front row of small tension springs 5 ​​is connected to the bottom of the front panel of the sliding housing 1. The top of the rear row of small tension springs 5 ​​is fixedly connected to the bottom of the back panel of the sliding housing 1. Multiple internal sliding rods 7 are fixedly installed through the middle of the side wall sliding block 6. Sliding grooves 8 for use with the internal sliding rods 7 are provided on both the front and back of the operating plate 2. One end of the internal sliding rod 7 is slidably connected to the inner wall of the sliding groove 8 on the surface of the operating plate 2. Through the side wall sliding block 6 and the small tension springs 5, the sliding housing 1 is constrained vertically while also providing a certain amount of buffer displacement, allowing the coating cylinder 12 to smoothly perform vertical buffer displacement according to the thickness of the packaging cardboard 4 when applying glue to it, ensuring normal glue application to the packaging cardboard 4. A stepper motor 9 is fixedly mounted on the front of the moving housing 1. The output shaft of the stepper motor 9 is fixedly connected to one end of the shaft rotating rod 10. The other end of the shaft rotating rod 10 is inserted into the interior of the sliding housing 1 and slidably connected to the inner wall of the sliding housing 1. An outer sleeve roller 11 is fixedly sleeved on the surface of the shaft rotating rod 10. A smooth coating cylinder 12 is fixedly sleeved on the surface of the outer sleeve roller 11. An outer semi-circular roller 13 is sleeved on the surface of the smooth coating cylinder 12. The inner wall of the outer semi-circular roller 13 is in sliding contact with the outer surface of the smooth coating cylinder 12. A glue storage cylinder 14 is fixedly installed on the top of the outer semi-circular roller 13. The glue storage cylinder 14 contains glue for applying glue. The top of the outer semi-circular roller 13 has multiple drip holes 15 for dripping glue. The glue storage cylinder 14 is internally connected to the outer semi-circular roller 13 and the drip hole 15. This allows the glue inside the storage cylinder 14 to penetrate through the drip hole 15 into the tightly sealed gap between the smooth coating cylinder 12 and the outer semi-circular roller 13, ensuring even application of the glue to the rotating smooth coating cylinder 12. Simultaneously, the rotating smooth coating cylinder 12, from below, evenly coats the surface of the packaging cardboard 4 with a suitable amount of glue, ensuring uniform gluing of the packaging cardboard 4. The top of the glue storage cylinder 14 is inserted into the cap 16 and threadedly connected to the inner wall of the cap 16. A threaded inner push rod 17 is threaded through the middle of the cap 16, and the surface of the threaded inner push rod 17 is threadedly connected to the inner wall of the cap 16.The bottom end of the threaded inner push rod 17 is rotatably connected to the piston inner push plate 18. The periphery of the piston inner push plate 18 is in pressure contact with the inner wall of the glue storage cylinder 14. Through the arrangement of the threaded inner push rod 17 and the piston inner push plate 18, the threaded inner push rod 17 can be used to drive the piston inner push plate 18 to push downward inside the glue storage cylinder 14, that is, to squeeze the glue downward so that it can smoothly seep out from the drip hole 15, ensuring that the glue supply applied to the smooth surface of the coating cylinder 12 is sufficient and uniform. The surface of the glue storage cylinder 14 is slidably fitted with a top support push cylinder 19 and a centrally placed pressure ring cylinder 22. The bottom of the 9 is inserted into the interior of the sliding housing 1. The central sleeve pressure ring cylinder 22 is located inside the sliding housing 1. Positioning slide blocks 20 are fixedly installed on both the front and back of the glue storage cylinder 14. The surface of the positioning slide block 20 is slidably connected to the inner wall of the top support push cylinder 19 and the central sleeve pressure ring cylinder 22. The surface of the top support push cylinder 19 is provided with a threaded groove. An adjusting outer rotating sleeve 21 is threadedly fitted on the surface of the top support push cylinder 19. The bottom edge of the adjusting outer rotating sleeve 21 is rotatably connected to the top surface of the sliding housing 1. Arc push side plates 23 are hinged on both sides of the central sleeve pressure ring cylinder 22. A rotating part is rotatably installed at the bottom of the arc push side plate 23. The rotating roller pressure cylinder 25, through the arrangement of the top support push cylinder 19, the adjusting outer rotating sleeve 21, the central sleeve pressure ring cylinder 22, and the arc push side plate 23, achieves the function of rotating and adjusting the outer rotating sleeve 21. Utilizing the threaded propulsion principle with the top support push cylinder 19, the top support push cylinder 19 pushes the central sleeve pressure ring cylinder 22 downward, changing the top support position of the central sleeve pressure ring cylinder 22. This adjusts the vertical height of the rotation point of the arc push side plate 23. Combined with the elastic force of multiple natural springs 24, it adjusts the downward swinging force of the rotating roller pressure cylinder 25, thus achieving the ability to adjust the rotating roller of the packaging cardboard 4 according to usage requirements. The pressure applied by the pressure cylinder 25 ensures a smoother and more stable gluing process for the packaging cardboard 4. Multiple natural springs 24 are fixedly installed on the arc-shaped inner wall of the arc-shaped push side plate 23. The other end of each natural spring 24 is fixedly connected to the arc-shaped outer surface of the outer semi-arc roller 13. The natural springs 24 utilize elastic force to provide a certain constraint on the swing of the arc-shaped push side plate 23, allowing the rotating pressure cylinder 25 to buffer displacement in the vertical direction while ensuring continuous pressure and positioning of the packaging cardboard 4.

[0016] In use, place the packaging cardboard 4 to be glued directly on the operating plate 2, then start the stepper motor 9, and then hold the push handle 3 to push the device horizontally and at a constant speed, so that the packaging cardboard 4 passes through the glue-applying opening on the side of the sliding housing 1 at a constant speed. When passing through the sliding housing 1, the stepper motor 9 drives the inner outer roller 11 to rotate again. The glue inside the glue storage cylinder 14 permeates through the drip hole 15 into the tightly closed gap between the smooth coating cylinder 12 and the outer semi-circular roller 13, so that the glue can be evenly applied to the surface of the rotating smooth coating cylinder 12. At the same time, the rotating smooth coating cylinder 12 passes through... The appropriate amount of glue adhering to its surface is evenly applied to the surface of the packaging cardboard 4 by a roller brush, ensuring that the packaging cardboard 4 is evenly coated with glue. Simultaneously, while the smooth coating cylinder 12 is applying glue to the packaging cardboard 4, the arc-shaped side plates 23 on both sides of the centrally located pressure ring cylinder 22 provide support for the rotating roller pressure cylinder 25. Combined with the elastic force of the natural spring 24, this presses and positions the packaging cardboard 4 on both sides of the contact surface being coated by the smooth coating cylinder 12, ensuring greater stability of the packaging cardboard 4 during glue application. When glue needs to be added, the cap 16 is rotated to separate it from the glue storage cylinder 14. Then, pour the added glue into the glue storage cylinder 14. When it is necessary to increase the penetration rate of the glue inside the glue storage cylinder 14 through the drip hole 15, rotate the threaded inner push rod 17. Utilizing the threaded pushing principle of the threaded inner push rod 17, drive the piston inner push plate 18 to push downward inside the glue storage cylinder 14, thus squeezing the glue downward to smoothly seep out from the drip hole 15. This ensures that the glue supply to the smooth coating cylinder 12 is sufficient and uniform. When it is necessary to adjust the glue flow, adjust the pressure intensity of the outer rotating sleeve 21 on the packaging cardboard 4 downward. That is, rotate the adjusting outer rotating sleeve 21, utilizing the pressure intensity of the outer rotating sleeve 21 on the top. The threaded pushing principle of the push cylinder 19 causes it to push the central sleeve pressure ring cylinder 22 downward, changing the supporting position of the central sleeve pressure ring cylinder 22. This adjusts the vertical height of the rotation point of the arc push side plate 23. Combined with the elastic force of multiple natural springs 24, it adjusts the downward swinging force of the rotating roller pressure cylinder 25. This allows the pressure applied to the packaging paperboard 4 by the rotating roller pressure cylinder 25 to be adjusted according to usage requirements, making the gluing of the packaging paperboard 4 smoother and more stable. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0017] In summary, this small, hand-push type gluing device for packaging paper, through the coordinated use of the outer semi-circular roller 13, glue storage cylinder, drip hole 15, threaded inner push rod 17, and piston inner push plate 18, achieves the following: by fitting the outer semi-circular roller 13 onto the surface of the smooth coating cylinder 12, and using the drip hole 15 opened in the middle of the outer semi-circular roller 13, the glue inside the glue storage cylinder 14 penetrates through the drip hole 15 into the tightly sealed gap between the smooth coating cylinder 12 and the outer semi-circular roller 13, and in conjunction with the light... The rotating use of the smooth coating brush 12 ensures that the gap between the surface of the smooth coating brush 12 and the inner wall of the outer semi-circular roller 13 is of equal size and very small. This results in a consistently uniform amount of adhesive applied to the rotating surface of the smooth coating brush 12 through the drip hole 15. Simultaneously, the smooth coating brush 12 rolls and applies the adhesive applied to its own surface evenly onto the surface of the packaging cardboard 4, achieving a uniform gluing effect. This is further enhanced by the top support pusher 19 and the adjustment of the outer... The combined use of the rotating sleeve 21, the central pressure ring cylinder 22, the arc-push side plate 23, the natural spring 24, and the rotating roller cylinder achieves the following: by setting the arc-push side plates 23 on both sides of the central pressure ring cylinder 22, the arc-push side plates 23 provide support for the rotating roller cylinder 25. Combined with the elastic force of the natural spring 24, the roller cylinder presses and positions the packaging cardboard 4 on both sides of the surface being coated by the smooth coating cylinder 12, ensuring greater stability of the packaging cardboard 4 during coating. This, along with adjusting the rotation of the outer rotating sleeve 21, facilitates the application of adhesives. Using the threaded propulsion principle of the top support pusher 19, the top support pusher 19 pushes the central sleeve pressure ring cylinder 22 downward, changing the top support position of the central sleeve pressure ring cylinder 22, so as to adjust the vertical height of the rotation point of the arc pusher side plate 23. In conjunction with the elastic force of multiple natural springs 24, the downward swing force of the rotating roller pressure cylinder 25 can be adjusted, that is, the pressure applied to the packaging paperboard 4 by the rotating roller pressure cylinder 25 can be adjusted according to the usage requirements, so that the packaging paperboard 4 is glued more smoothly.
