Description

Technical Field

[0001] This utility model relates to the field of gluing device technology, specifically a gluing device for packaging bag production and processing. Background Technology

[0002] Eco-friendly paper bags, also known as pure wood pulp paper bags or kraft paper bags, are made from plant fibers (such as bark, leaves, and branches) through chemical pulping, followed by beating in a pulping machine, adding sizing agents and dyes, and finally producing paper (i.e., roll paper) on a papermaking machine. The paper fibers have considerable tensile strength and are resistant to moisture, freezing temperatures, and melting temperatures without deformation, twisting, or breaking. It is named kraft paper because of its strong and tough texture, resembling cowhide. Sealing the edges is an essential step in making paper bags of various sizes.

[0003] A patent search revealed a document titled "A Glue Applying Device for Paper Product Packaging Bags" (publication number "CN220146823U"). This device fails to control the amount of glue applied. While it collects excess glue in a recycling bin, the discharged glue has already come into contact with external objects, meaning the recycled glue is in an unclean state. The quality of the glue cannot be guaranteed, making it unusable for re-applying to packaging bags and resulting in waste. Therefore, this invention designs a glue applying device for packaging bag production to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 A preferred embodiment of the gluing device for packaging bag production and processing provided by this utility model is, for example... Figures 1 to 4The following describes a gluing device for packaging bag production and processing, comprising an operating table 1, a limiting plate 2 fixedly disposed at the top center of the operating table 1, a support 3 fixedly disposed at the top of the operating table 1, a box 4 fixedly disposed at the top of the support 3, and an inner liner 5 fixedly disposed inside the box 4; discharge holes 6 integrally disposed on the left and right sides inside the box 4, and a one-way valve 7 fixedly disposed inside the discharge holes 6; and a drive assembly 8 assembled inside the inner liner 5, which controls the amount of glue discharged from the box 4 into the inner liner 5. The drive assembly 8 includes a slidingly disposed inside the inner liner 5. Slide 801; a pull rod 802 fixed to the top of slide 801, the pull rod 802 sliding through the box 4; a handle 803 fixed to the outer wall of the pull rod 802; a limiting block 804 set inside the inner liner 5 on the left side; a cavity 9 integrally set inside the top of the bracket 3; several nozzles 10 fixed from left to right inside the top of the bracket 3; a first valve 11 rotatably passing through the nozzles 10; a connector 12 integrally set inside the bottom middle side of the box 4; the connector 12 fixedly passing through the bracket 3; a check valve 13 fixed inside the connector 12.

[0022] It should be noted that existing gluing devices used in packaging bag production and processing still have certain shortcomings in actual use. They cannot control the amount of glue discharged to the outside, resulting in waste of glue.

[0023] In this embodiment, the worker first places the packaging bag on the operating table 1, so that the rear edge of the packaging bag is in contact with the limiting plate 2. At this time, the glue application area of ​​the packaging bag overlaps with the nozzle 10. The worker then closes the first valve 11, which is not overlapping with the packaging bag, to prevent the glue sprayed from the nozzle 10 beyond the edge of the packaging bag from falling onto the operating table 1. The worker then pulls the handle 803 upwards. The handle 803 drives the pull rod 802, which in turn moves the sliding plate 801 upwards along the direction of the inner liner 5. The slide plate 801 draws the adhesive from inside the box 4 through the discharge hole 6 into the inner liner 5. When the slide plate 801 comes into contact with the limit block 804, the amount of adhesive discharged into the inner liner 5 is controlled. The operator then pulls down the handle 803, which causes the slide plate 801 to squeeze the adhesive from inside the inner liner 5 through the connector 12, through the cavity 9, and through the nozzle 10 to apply it to the adhesive application area of ​​the packaging bag. The one-way valve 7 can prevent the adhesive in the inner liner 5 from flowing back into the box 4, and the check valve 13 can prevent the adhesive in the cavity 9 from flowing back into the inner liner 5.

[0024] In a further preferred embodiment of the present invention, a slide 14 is slidably passed through the front end of the bracket 3. The front cross-section of the slide 14 is rectangular. A non-stick roller 15 is rotatably sleeved on the lower end of the slide 14. Springs 16 are sleeved on the left and right sides of the upper end of the slide 14. One end of the spring 16 is fixedly connected to the slide 14, and the other end of the spring 16 is fixedly connected to the bracket 3.

[0025] In this embodiment, after the packaging bag is glued, the worker moves the packaging bag along the front end of the operating table 1 with his left hand. At the same time, the worker presses down the slide 14 with his right hand, and the spring 16 deforms. At this time, the slide 14 drives the non-stick roller 15 to be in a rolling friction state with the top surface of the packaging bag, so that the non-stick roller 15 can evenly coat the glue on the top surface of the packaging bag.

[0026] Example 2 Based on Example 1, a preferred embodiment of the gluing device for packaging bag production and processing provided by this utility model is as follows: Figures 1 to 4 As shown: An adjustment component is provided inside the inner liner 5. The adjustment component can adjust the distance between the limiting block 804 and the sliding plate 801. The adjustment component includes a guide groove 17 integrally set on the left side inside the inner liner 5, and the guide groove 17 is slidably connected to the limiting block 804; a rotating rod 18 is rotatably set on the left side inside the inner liner 5, the rotating rod 18 rotatably passes through the box body 4, and the rotating rod 18 is threaded through the limiting block 804. A sliding rod 19 is fixed on the top of the limiting block 804, and the sliding rod 19 slides through the box body 4. The body 4 has a parallel design with slide bar 19 and pull bar 802. A scale 20 is fixed on the top left side of the body 4. The scale 20 and slide bar 19 are parallel to each other and the distance between the scale 20 and slide bar 19 is three centimeters. An indicator strip 21 is fixed on the outer wall of slide bar 19. The indicator strip 21 corresponds to the scale 20 one by one. The length of the indicator strip 21 is two centimeters. A feed pipe 22 is fixedly inserted through the top left side of the body 4. A second valve 23 is rotatably inserted through the feed pipe 22.

[0027] In this embodiment, the operator can rotate the rotating rod 18. Through the threaded transmission design between the rotating rod 18 and the limiting block 804, the limiting block 804 moves along the guide groove 17 until the limiting block 804 drives the sliding rod 19 and the indicator strip 21 to the value on the scale 20, meeting the operator's needs. Then, the operator releases the rotating rod 18. This method adjusts the amount of adhesive collected inside the inner liner 5, allowing the discharged adhesive to be matched with packaging bags of different sizes. Furthermore, the operator can inject the adhesive into the box body 4 through the feed pipe 22 and then close the second valve 23.

[0028] In summary, this application allows for control over the amount of adhesive discharged to the outside, preventing waste. The device can adjust the amount of adhesive inside the inner liner to the range required by the operator, thus ensuring the discharged adhesive can be matched to packaging bags of different sizes. Through the displacement function design, the non-stick roller evenly coats the packaging bag with adhesive, improving the gluing effect.
