Description

Technical Field

[0001] This utility model relates to the field of paper corner protector production and processing technology, and in particular to a glue filtering device for a paper corner protector production line. Background Technology

[0002] Paper corner protectors, also known as edge boards, are one of the most popular packaging products currently available. They are used to replace wooden packaging and other bulky packaging methods, and are characterized by low price, light weight, sturdiness, and compliance with environmental protection requirements. Also known as paper corner protectors, edge boards, corner paper, or paper angle steel, they are made from yarn tube paper and kraft paper through a complete set of corner protector machines. Both ends are smooth and flat, without obvious burrs, and perpendicular to each other. They can replace wood and are 100% recyclable, making them one of the ideal new green packaging materials.

[0003] In the production of paper corner protectors, glue needs to be applied. During the glue application process, the scraper will scrape off the excess glue above for recycling, avoiding waste of resources. In the process of recycling glue, the glue needs to be filtered to prevent hardened glue particles from entering the glue storage bin and burdening subsequent glue application work.

[0004] The glue filtering devices in common paper corner protector production lines have a relatively simple structure. They usually only screen out the hardened glue particles and do not facilitate their melting and reuse, resulting in low glue utilization efficiency. Moreover, if there are other particulate impurities in the recycled glue, they need to be separated from the glue particles, which is a cumbersome process and not very convenient to use. Therefore, we propose a glue filtering device for paper corner protector production lines. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Common paper corner protector production lines have relatively simple glue filtering devices that typically only screen out hardened glue particles, making it inconvenient to melt and reuse them. This results in low glue utilization efficiency. Furthermore, if other particulate impurities are present in the recycled glue, they need to be separated from the glue particles, which is a cumbersome process and not very convenient to use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filter device for a paper corner protector production line includes a storage box, a collection mechanism installed at the top of the storage box, and a cleaning mechanism installed on the left side of the collection mechanism.

[0008] The collection mechanism includes a funnel installed at the top of the storage tank. Inside the funnel, near the right side, is a first hydraulic cylinder with its output end facing the left side. The output end of the first hydraulic cylinder extends into the interior of the cleaning mechanism and is fixedly connected to a metal filter plate. Inside the funnel, near the top, is a barrier component.

[0009] The cleaning mechanism includes a housing, which is fixedly installed on the top of the storage box near the left side. A cleaning component is installed inside the housing near the top. A baking lamp plate is installed inside the housing near the right side and below the cleaning component. A return groove is opened inside the housing near the right side.

[0010] As a preferred embodiment of this utility model, a discharge pipe is installed on the left side of the storage box.

[0011] The technical effect of adopting the above-mentioned further solution is that the glue recovered inside the storage box can be discharged through the discharge pipe and then transported by the external conveying equipment to perform a new glue application operation.

[0012] As a preferred embodiment of this utility model, the inner bottom of the storage box is a sloped structure that tilts to the left.

[0013] The technical effect of adopting the above-mentioned further solution is that the sloping structure at the bottom of the storage box can accelerate the flow of glue to the discharge pipe.

[0014] As a preferred embodiment of this utility model, the blocking component includes a support frame, which is fixedly connected to the inside of the funnel. A second hydraulic cylinder with its output end facing the top is installed at the top of the support frame, and a sealing block is fixedly connected to the output end of the second hydraulic cylinder.

[0015] The technical effect of adopting the above-mentioned further solution is that when the first hydraulic cylinder pushes the metal filter plate into the housing, the contraction of the second hydraulic cylinder can drive the sealing block to move downward, thereby sealing the channel between the funnel and the storage tank. This can prevent the glue from flowing directly into the storage tank without being filtered by the metal filter plate, thus improving the stability of use.

[0016] As a preferred embodiment of this utility model, the sealing block is a hollow triangular metal structure.

[0017] The technical advantages of adopting the above-mentioned further solution are: the hollow structure of the sealing block can reduce the weight and the workload of the second hydraulic cylinder, while the triangular structure can make the glue dripping on it slide down along both sides, improving the glue recycling effect.

[0018] As a preferred embodiment of this utility model, the cleaning component includes a motor, which is fixedly installed inside the housing. A lead screw is fixedly connected to the output end of the motor, and the lead screw is rotatably connected to the housing. A slider is sleeved around the lead screw, and a third hydraulic cylinder with its output end facing down is installed at the bottom of the slider. A scraper is welded to the output end of the third hydraulic cylinder.

[0019] The technical effect of adopting the above-mentioned further solution is that the motor can drive the lead screw to rotate, thereby causing the lead screw to drive the third hydraulic cylinder and scraper to move left and right through the slider. The extension of the third hydraulic cylinder drives the scraper to adhere to the surface of the metal filter plate, and under the action of the slider, other particulate impurities on the metal filter plate are scraped off into the drawer box, thus completing the cleaning.

[0020] As a preferred embodiment of this utility model, the reflux trough is opened at an angle inclined to the right and is connected to the funnel.

[0021] The technical effect of adopting the above-mentioned further solution is that the inclined reflux channel helps the melted glue flow into the funnel, thereby improving the glue utilization efficiency.

[0022] As a preferred embodiment of this utility model, a drawer box is slidably installed on the left side of the housing near the bottom.

[0023] The technical advantage of adopting the above-mentioned further solution is that other particulate impurities can be collected by using a drawer, thus improving ease of use.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] In this invention, through the design of the storage box, collection mechanism, and cleaning mechanism, the metal filter plate containing glue particles and other material particles is pushed into the housing by the first hydraulic cylinder. Under the action of the heating lamp plate, the glue particles are heated and melted, turning them back into flowable glue. This allows the glue to flow back into the funnel through the return groove for recycling, improving the glue utilization efficiency. Meanwhile, other material particles fall into the drawer for unified processing under the scraping action of the scraper, effectively improving the ease of use. Attached Figure Description

[0035] Example 1

[0036] like Figure 1-4As shown, this utility model provides a technical solution: a filter device for a paper corner protector production line, including a storage box 1, a collection mechanism 2 installed at the top of the storage box 1, a cleaning mechanism 3 installed on the left side of the collection mechanism 2, the collection mechanism 2 including a funnel 201, the funnel 201 installed at the top of the storage box 1, a first hydraulic cylinder 202 with its output end facing left is installed inside the funnel 201 near the right side, the output end of the first hydraulic cylinder 202 extends into the cleaning mechanism 3 and is fixedly connected to a metal filter plate 203, a blocking component 204 is installed inside the funnel 201 near the top, the cleaning mechanism 3 including a housing 301, the housing 301 is fixedly installed at the top of the storage box 1 near the left side, a cleaning component 302 is installed inside the housing 301 near the top, a baking lamp plate 303 is installed inside the housing 301 near the right side and below the cleaning component 302, and a return groove 304 is opened inside the housing 301 near the right side.

[0037] Example 2

[0038] like Figure 1-4As shown, a discharge pipe 101 is installed on the left side of the storage tank 1. The discharge pipe 101 allows the recycled glue inside the storage tank 1 to flow out and be conveyed by an external conveying device for a new glue application operation. The inner bottom of the storage tank 1 has a sloped structure that slopes to the left, which accelerates the flow of glue to the discharge pipe 101. The blocking component 204 includes a support frame 2041, which is fixedly connected to the inside of the funnel 201. A second hydraulic cylinder 2042 with its output end facing the top is installed on the top of the support frame 2041. A sealing block is fixedly connected to the output end of the second hydraulic cylinder 2042. 2043. When the first hydraulic cylinder 202 pushes the metal filter plate 203 into the housing 301, the contraction of the second hydraulic cylinder 2042 can drive the sealing block 2043 to move downward, thereby sealing the channel between the funnel 201 and the storage tank 1. This prevents glue from flowing directly into the storage tank 1 without being filtered by the metal filter plate 203, improving operational stability. The sealing block 2043 is a hollow triangular metal structure. The hollow structure of the sealing block 2043 reduces weight and the workload of the second hydraulic cylinder 2042. At the same time, the triangular structure allows glue dripping above it to slide off along both sides. To improve the recycling efficiency of adhesive, the cleaning component 302 includes a motor 3021, which is fixedly installed inside the housing 301. A lead screw 3022 is fixedly connected to the output end of the motor 3021. The lead screw 3022 is rotatably connected to the housing 301. A slider 3023 is sleeved around the lead screw 3022. A third hydraulic cylinder 3024 with its output end facing downwards is installed at the bottom of the slider 3023. A scraper 3025 is welded to the output end of the third hydraulic cylinder 3024. The motor 3021 drives the lead screw 3022 to rotate, thereby causing the lead screw 3022 to drive the third hydraulic cylinder 3024 and the scraper 3025 via the slider 3023. 5. Moving left and right, the extension of the third hydraulic cylinder 3024 drives the scraper 3025 to adhere to the surface of the metal filter plate 203, and under the action of the slider 3023, other particulate impurities on the metal filter plate 203 are scraped out into the drawer box 3011, completing the cleaning. The return channel 304 is opened at a right-angled angle and is connected to the funnel 201. The inclined return channel 304 helps the melted glue to flow into the funnel 201, improving the utilization efficiency of the glue. The drawer box 3011 is slidably installed on the left side of the housing 301 near the bottom. Other particulate impurities can be collected through the drawer box 3011, improving the convenience of use.

[0039] The working process of this utility model is as follows: When recycling hardened glue particles in the glue filtering device of a paper corner protector production line, firstly, the second hydraulic cylinder 2042 drives the sealing block 2043 downward to block the channel between the funnel 201 and the storage box 1. Then, the first hydraulic cylinder 202 pushes the metal filter plate 203 into the housing 301. Afterward, the hardened glue particles on the metal filter plate 203 are heated and melted by the baking lamp plate 303, allowing them to pass through the metal filter plate 203 and flow back into the funnel 201 through the return groove 304, thus completing the recycling. This effectively improves the utilization efficiency of the glue, while preventing the glue from melting. Other particulate impurities will remain on the metal filter plate 203. The motor 3021 drives the lead screw 3022 to rotate, which in turn causes the lead screw 3022 to drive the slider 3023 to move the third hydraulic cylinder 3024 and scraper 3025 to the right above the metal filter plate 203. The extension of the third hydraulic cylinder 3024 causes the scraper 3025 to approach the top of the metal filter plate 203. The motor 3021 and lead screw 3022 then drive the scraper 3025 to move to the left, thereby scraping other particulate impurities down into the drawer box 3011 for unified processing. This eliminates the need for sorting and effectively improves ease of use.
