Description

Technical Field

[0001] This utility model belongs to the technical field of valve bag adhesive coating plate, and in particular relates to a dense adhesive coating plate for uniform adhesive application. Background Technology

[0002] Valve bags, commonly known as bottom-sealed bags, are packaging bags that are fed through a valve at the top or bottom. They are filled using specialized equipment and then shaped into cubes. They are characterized by high filling efficiency, neat stacking, sturdiness, convenient transportation, and an attractive appearance. Classified as environmentally friendly bags, they are widely used for packaging powdered or granular solid materials and flexible items such as edible powders, chemical powders, fertilizers, synthetic materials, explosives, grains, salt, and minerals. In valve bag production, adhesive is applied to the seams of the packaging material to bond them together. The adhesive application at the seams of valve bag packaging is primarily done using rollers, where the relative movement of the adhesive plate and rollers completes the adhesive application. However, this method still has the following drawbacks in practical use:

[0003] In the production of valve bags that meet production requirements, it is necessary to ensure that the glue is applied as fully as possible in order to achieve good glue application. However, due to gaps and structure of the glue plate, the amount of glue may be too thick or too thin during the glue application, which seriously affects the product quality.

[0004] Secondly, during the gluing process, the glue is contained in the bottom box, with most of the space exposed to the air. As the work progresses, dust in the air will fall into the glue, causing it to become contaminated and affecting its adhesion after application. Utility Model Content

[0005] The purpose of this invention is to provide a dense gluing plate for uniform gluing. By setting up a gluing plate roller, a connecting plate, a bottom box, and a cover plate, it solves the problem that the gluing plate is prone to excessive or insufficient glue application during gluing, and that the glue is easily contaminated by dust in the air when it is directly exposed in the bottom box.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a uniformly coated and densely coated printing plate, comprising a printing plate roller, a connecting plate, a base box, and a cover plate. The base box is movably connected to the lower part of the printing plate roller. A support plate is fixed to one long side of the top of the base box. A connecting plate is fixed to the upper part of the support plate near the printing plate roller. An elastic sleeve is fixed to the upper part of the connecting plate near the printing plate roller. A scraper is fixed to the upper part of the elastic sleeve near the printing plate roller. Rhomboid holes are evenly distributed around the periphery of the printing plate roller, and adjacent... Channels are provided around the periphery of the gluing roller between the diamond-shaped holes. A cover plate is fixed on the upper part of the inner wall of the bottom box away from the support plate. During operation, the gluing roller picks up the glue from the bottom box as it rotates. The elastic sleeve connected to the connecting plate abuts the scraper against the gluing roller, so that the excess glue on the gluing roller is scraped off. The bottom box contains the glue from the gluing roller used to apply glue to the valve pocket. The cover plate and the connecting plate cooperate with each other, and with the cooperation of the gluing roller, dust is reduced from entering the bottom box.

[0008] Furthermore, a rotating shaft is fixed at the center of both ends of the printing plate roller, and the rotating shaft is located above the bottom box. A meshing gear is fixed at the end of one of the rotating shafts away from the printing plate roller. When the meshing gear of the rotating shaft at the end of the printing plate roller rotates, it drives the printing plate roller to rotate.

[0009] Furthermore, both ends of the connecting plate are fixed with baffles, the bottom of the baffles is fixed to the top of the bottom box, and both baffles are in contact with the gluing roller. The scraper abuts against the periphery of the gluing roller. The baffles prevent glue from leaking out from the end of the gluing roller as the gluing roller rotates.

[0010] Furthermore, both ends of the bottom box are fixed with limiting plates. The bottom end of the limiting plate is flush with the bottom of the bottom box, and the limiting plate extends above the bottom box. The limiting plate on the bottom box is connected to limit the position of the printing plate roller.

[0011] Furthermore, a movable hole is provided through the limiting plate above the bottom box, and the two rotating shafts are respectively movably connected to the movable holes on the two limiting plates, with the movable holes on the limiting plates movably connected to the rotating shafts.

[0012] Furthermore, a glue injection tube is fixedly installed through the center of the cover plate. The cover plate is located outside the glue roller. After inserting the glue injection nozzle into the glue injection tube, the glue can be injected into the bottom box.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of excessively thick or thin glue application during the gluing process by setting up a gluing roller, a connecting plate, and a base box. The gluing roller rotates with the rotating shaft. The lower circumferential side of the gluing roller enters the glue in the base box and adheres to the glue. As it rotates, it moves to the circumferential contact scraper. Under the elastic action of the elastic sleeve fixed by the connecting plate, the scraper abuts against the circumferential side of the gluing roller, scraping off the excess glue. After the excess glue is scraped off, the circumferential side of the gluing roller rotates and rises to the upper position, where the valve bag gluing operation can be performed. After the gluing roller comes into contact with the glue, the pores and channels on its circumference are filled with glue, and the glue adheres to the circumference of the gluing roller. After the excess glue is scraped off, the pores and channels are connected, making the glue content in the pores more uniform. This allows for uniform glue application during operation and ensures that the glue is neither too thick nor too thin, guaranteeing the quality of valve bag bonding.

[0015] This invention solves the problem of adhesive used in applying glue being easily contaminated by dust in the air when it is directly exposed in the bottom box by setting up an application roller, a connecting plate, a bottom box, and a cover plate. The glue nozzle is inserted into the glue injection tube, and then the glue is delivered to the bottom box. After the glue is delivered to the bottom box, the top of the bottom box forms a closed structure through the cooperation of the cover plate, the connecting plate, and the application roller, which effectively reduces the amount of dust falling in and prevents the glue from being contaminated. This ensures that the glue used in applying glue is well protected after entering the bottom box and is not contaminated by dust. Attached Figure Description

[0026] 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. Specific Implementation Example 1

[0027] Please see Figure 1-6 This utility model is a uniformly glued, densely glued printing plate, including a glued printing roller 1, a connecting plate 2, a bottom box 3, and a cover plate 4. The bottom box 3 is movably connected to the lower part of the glued printing roller 1. When the glued printing roller 1 rotates, the glue in the bottom box 3 is applied to it, preparing for glue application to the valve pocket. The bottom box 3 is used to hold the glue. A support plate 201 is fixed to one long side of the top of the bottom box 3. The support plate 201 supports and fixes the connecting plate 2 to the bottom box 3. The connecting plate 2 is fixed to the upper part of the support plate 201 near the glued printing roller 1. An elastic sleeve 203 is connected to the connecting plate 2. The elastic sleeve 203 is fixed to the connecting plate 2 near the glued printing roller 1. A scraper 204 is fixed to the upper part of one side of the printing roller 1. An elastic sleeve 203 provides elasticity, pushing the scraper 204 to abut against the printing roller 1 and scraping off excess glue on the printing roller 1. The printing roller 1 has evenly distributed diamond-shaped holes 103 on its periphery, and channels 104 are opened on the periphery of the printing roller 1 between adjacent diamond-shaped holes 103. The depth of the diamond-shaped holes 103 is relatively shallow, and during operation, the channels 104 make the adjacent diamond-shaped holes 103 connected, and the glue content in the adjacent diamond-shaped holes 103 is more uniform. A cover plate 4 is fixed to the upper part of the inner wall of the bottom box 3 on the side away from the support plate 201. The cover plate 4 closes the top of the bottom box 3 on the side away from the connecting plate 2.

[0028] Specifically, a rotating shaft 101 is fixed at the center of both ends of the printing roller 1, and the rotating shaft 101 is located above the bottom box 3. A meshing gear 102 is fixed at the end of one rotating shaft 101 away from the printing roller 1. When the rotating shaft 101 rotates, it drives the printing roller 1 to rotate. The meshing gear 102 meshes with the driving gear, driving the printing roller 1 to rotate.

[0029] Furthermore, baffles 202 are fixed at both ends of the connecting plate 2. The bottom of the baffles 202 is fixed to the top of the bottom box 3, and both baffles 202 are in contact with the gluing roller 1. The scraper 204 abuts against the periphery of the gluing roller 1. When the connecting plate 2 is working, the baffles 202 on it are fixed to the bottom box 3, so that when the baffles 202 are in contact with the gluing roller 1, the glue on the periphery of the gluing roller 1 will not overflow into the bottom box 3.

[0030] Furthermore, both ends of the bottom box 3 are fixed with limit plates 301. The bottom end of the limit plate 301 is flush with the bottom of the bottom box 3. The limit plate 301 extends above the bottom box 3. The limit plate 301 is connected to the rotating shaft 101 to support the upper printing roller 1.

[0031] Furthermore, a movable hole 302 is provided through the limiting plate 301 above the bottom box 3, and two rotating shafts 101 are respectively movably connected to the movable holes 302 on the two limiting plates 301, so that the gluing roller 1 is supported above the bottom box 3.

[0032] The operation process of this embodiment is as follows: During operation, after the meshing gear 102 meshes with the driving gear, the driving gear rotates, causing the meshing gear 102 to rotate. The gluing roller 1 rotates with the rotation of the rotating shaft 101. The peripheral side of the gluing roller 1 located at the lower part enters the glue in the bottom box 3 and adheres to the glue. As it rotates, it moves to the peripheral side to contact the scraper 204. Under the elastic action of the elastic sleeve 203 fixed by the connecting plate 2, the scraper 204 abuts against the peripheral side of the gluing roller 1 and scrapes off the excess glue on the peripheral side of the gluing roller 1. After the excess glue is scraped off, the peripheral side of the gluing roller 1 rotates and rises to the upper part, and the valve bag gluing operation can be performed. After the gluing roller 1 contacts the glue, the pores 103 and channels 104 on its peripheral side are filled with glue, and the glue adheres to the peripheral side of the gluing roller 1. After the excess glue is scraped off, the pores 103 and channels 104 are connected, making the glue content in the pores 103 more uniform. Specific Implementation Example 2

[0033] Please see Figure 1-7 Based on the first specific embodiment, a glue injection tube 401 is fixedly fixed in the center of the cover plate 4. The cover plate 4 is located outside the upper glue roller 1. The cover plate 4 closes the upper part of the bottom box 3. When glue needs to be added, the glue injection nozzle is inserted into the glue injection tube 401 so that the glue is delivered into the bottom box 3 through the glue injection tube 401.

[0034] The operation process of this embodiment is as follows: During operation, the glue injection nozzle is inserted into the glue injection tube 401, and then the glue is delivered to the bottom box 3. After the glue is delivered to the bottom box 3, the cover plate 4 and the connecting plate 2 cooperate with each other and cooperate with the glue application roller 1, so that the top of the bottom box 3 can effectively reduce dust falling into the bottom box 3 and prevent the glue from being contaminated.
