Description

Technical Field

[0001] This utility model relates to the technical field of plywood gluing devices, specifically a gluing device for plywood processing. Background Technology

[0002] A plywood coating device is a specialized piece of equipment used to uniformly apply adhesive to the surface of plywood. It is widely used in the manufacturing of engineered wood products, furniture production, and building decoration materials. In the continuous production of plywood, the quality of the adhesive application directly affects the bonding strength, flatness, and environmental performance of the final product. Therefore, an efficient, uniform, and adjustable adhesive application process is crucial. Existing coating devices typically include an adhesive storage system, a conveying mechanism, and a spraying or roller coating mechanism. Mechanical transmission drives the plywood to move, completing the adhesive spraying and coating during the process to achieve automated continuous operation.

[0003] However, traditional glue application equipment makes it difficult to thoroughly clean the inside of the spray nozzle when it is shut down or the type of glue is changed. Residual glue can easily solidify inside the spray nozzle, causing blockage and uneven glue dispensing, which seriously affects the quality of subsequent glue application. In addition, it requires frequent disassembly and cleaning, resulting in a large workload and long maintenance time. Utility Model Content

[0026] This application provides a glue-applying device for plywood processing. This device, through the inclusion of a cleaning component, allows for the removal and removal of residual glue from the transparent glue spray tube after application using a scraper, facilitating rapid cleaning of the spray tube's interior. The following provides a detailed description of this glue-applying device for plywood processing. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figure 1-9 In this embodiment, a glue-applying device for plywood processing is provided, including: a support 1, a glue storage tank 5 at the bottom of the support 1, a bracket 6 installed at the top of the support 1, and a detachable transparent glue-spraying tube 2 installed at the top of the support 1; and a cleaning assembly disposed inside the transparent glue-spraying tube 2, the cleaning assembly including: a threaded cap 202, a piston a 204, a pull rod 205, a scraper 206, a piston b 207, a feed pipe 208, a screw cap 209, and a connecting pipe 3.

[0029] The cleaning component allows residual glue inside the transparent spray tube 2 to be scraped off and pushed outward by the scraper 206 after the glue is applied, facilitating quick cleaning of the inside of the transparent spray tube 2 and preventing glue from solidifying and clogging.

[0030] Among them, a motor 103 is installed on one side of the support 1. A drive sprocket 102 is driven and connected to one side of the motor 103 via a rotating shaft. A drive roller 104 is fixedly connected to one side of the drive sprocket 102. Multiple driven sprockets 101 are provided on one side of the support 1. Driven rollers 105 are connected to one side of the multiple driven sprockets 101. One end of the drive roller 104 and the multiple driven rollers 105 are connected to the support 1 via bearings. Pull plates 402 are provided on both sides of the support 1. Two threaded rods 4 are fixedly connected to one end of each pull plate 402. A push plate 401 is fixedly connected to one end of each threaded rod 4. Nuts 403 are threadedly connected to each of the two threaded rods 4. A chain 110 is provided between the drive sprocket 102 and the driven sprockets 101.

[0031] In use, the controller starts the motor 103, which rotates the drive sprocket 102 and drives the chain 110 to rotate, thereby driving multiple driven sprockets 101 to rotate, which in turn causes the drive roller 104 and multiple driven rollers 105 to rotate, making the plywood move toward the brush 109.

[0032] In use, place a piece of plywood to be coated with glue on the top center of the driven roller 105, then loosen the two nuts 403 on the multiple threaded rods 4 to allow the threaded rods 4 to move left and right. Then push or pull the pull plate 402 to bring one side of the push plate 401 against the side of the plywood. At this point, it is only necessary to bring it close enough so that the plywood does not shift significantly during transport; it is not necessary to press it against both sides of the plywood. Then tighten the nuts 403 on the multiple threaded rods 4 to fix the threaded rods 4 to the support 1. In addition, depending on the width of the plywood, the threaded cap 202 can be turned to move away from the transparent glue spray tube 2, thereby driving the pistons b207 and a204 to move to the right. Since the transparent spray tube 2 is made of transparent material, the position of the piston b207 inside the transparent spray tube 2 can be directly observed. When the piston b207 moves to the appropriate position and is located on the right side of part of the spray hole 210, the sealing rubber ring on the outside of the piston b207 will block the glue from flowing into the spray hole 210 on the left side of the piston b207, so that the glue cannot flow out of that part of the spray hole 210, thereby adjusting the spray range. In addition, the thread length at one end of the transparent spray tube 2 is one-quarter of the length of the transparent spray tube 2, which is the distance between the piston b207 at the innermost part of the cavity of the transparent spray tube 2 and the bottom of the feed tube 208. Therefore, the adjustable spray range is within one-quarter of the length of the transparent spray tube 2.

[0033] The support 1 has a through hole a106 on one side, and three limiting slots 107 are formed on the inner wall of the through hole a106. A limiting hole 108 is also formed on one side of the support 1. Three limiting blocks 201 are fixedly connected to the outside of the transparent adhesive tube 2. The transparent adhesive tube 2 is located inside the through hole a106 and the limiting hole 108. One end of the transparent adhesive tube 2 has an external thread, and one end of the transparent adhesive tube 2 has a threaded cap 202. The threaded cap 202 has an internal thread that mates with the external thread on the outside of the transparent adhesive tube 2. The transparent adhesive tube 2 and... The threaded cap 202 is threaded, and the bottom of the inner wall of the transparent spray tube 2 has multiple spray holes 210; the limiting block 201 is slidably connected to the limiting slot 107; a connecting rod 203 is fixedly connected to one side of the threaded cap 202; a piston a204 is fixedly connected to one end of the connecting rod 203; a pull rod 205 is fixedly connected to one end of the piston a204; a scraper 206 is fixedly connected to one end of the pull rod 205; a piston b207 is connected to one side of the scraper 206; and sealing rubber rings are installed on the outer sides of both piston a204 and piston b207.

[0034] When the spraying is completed and the adhesive inside the transparent spray tube 2 needs to be cleaned to prevent it from solidifying, unscrew the threaded cap 202 so that one end of the threaded cap 202 is completely unscrewed from one side of the transparent spray tube 2. Pull the threaded cap 202 to move the piston a204, scraper 206 and piston b207 outward. At this time, the scraper 206 can scrape out the adhesive remaining inside the transparent spray tube 2 to clean the adhesive inside the transparent spray tube 2.

[0035] The transparent spray tube 2 is fixedly connected to the top of the feed tube 208, the top of the feed tube 208 is provided with a connecting tube 3, the bottom of the connecting tube 3 is fixedly connected with a limit ring 301, the glue storage tank 5 is connected to one side of the glue extraction tube 501, and the support 1 is installed on one side of the support. The feed tube 208 is provided with an external thread, the connecting tube 3 is fitted with a screw cap 209, the bottom of the screw cap 209 is provided with an internal thread that matches the external thread of the feed tube 208, the feed tube 208 is threadedly connected to the screw cap 209, and a sealing ring is fixedly installed at the top of the feed tube 208. The support 1 is fixedly installed with a bracket 6, the bracket 6 is installed with a glue extraction pump 502, one side of the glue extraction pump 502 is connected to the glue extraction tube 501, one side of the glue extraction pump 502 is connected to a glue dispensing hose 503, and one end of the glue dispensing hose 503 is fixedly connected to the connecting tube 3.

[0036] When the plywood moves to the bottom of the transparent glue spray tube 2, the glue pump 502 is activated by the controller. The glue pump 502 draws glue from the glue storage tank 5, and the glue flows through the glue extraction tube 501 and the glue outlet hose 503 into the connecting pipe 3 and the feed pipe 208. It then enters the space between pistons b207 and a204 inside the transparent glue spray tube 2, and flows onto the plywood from multiple glue spray holes 210. As the drive roller 104 and driven roller 105 rotate, the plywood moves to the conveyor mechanism for the next process. When the plywood leaves the top of the drive roller 104 and driven roller 105, the soft bristles at the bottom of the brush 109 apply glue to the top of the plywood, covering it with glue.

[0037] The working principle is as follows:

[0038] In use, place a piece of plywood to be coated with glue on the top center of the driven roller 105, then loosen the two nuts 403 on the multiple threaded rods 4 to allow the threaded rods 4 to move left and right. Then push or pull the pull plate 402 to bring one side of the push plate 401 against the side of the plywood. At this point, it is only necessary to bring it close enough so that the plywood does not shift significantly during transport; it is not necessary to press it against both sides of the plywood. Then tighten the nuts 403 on the multiple threaded rods 4 to fix the threaded rods 4 to the support 1. In addition, depending on the width of the plywood, the threaded cap 202 can be turned to move away from the transparent glue spray tube 2, thereby driving the pistons b207 and a204 to move to the right. Since the transparent spray tube 2 is made of transparent material, the position of the piston b207 inside the transparent spray tube 2 can be directly observed. When the piston b207 moves to the appropriate position and is located on the right side of part of the spray hole 210, the sealing rubber ring on the outside of the piston b207 will block the glue from flowing into the spray hole 210 on the left side of the piston b207, so that the glue cannot flow out of that part of the spray hole 210, thereby adjusting the spray range. In addition, the thread length at one end of the transparent spray tube 2 is one-quarter of the length of the transparent spray tube 2, which is the distance between the piston b207 at the innermost part of the cavity of the transparent spray tube 2 and the bottom of the feed tube 208. Therefore, the adjustable spray range is within one-quarter of the length of the transparent spray tube 2.

[0039] Then, the controller starts the motor 103, which rotates the drive sprocket 102 and drives the chain 110 to rotate, thereby driving multiple driven sprockets 101 to rotate, which in turn causes the drive roller 104 and multiple driven rollers 105 to rotate, causing the plywood to move toward the brush 109.

[0040] When the plywood moves to the bottom of the transparent glue spray tube 2, the glue pump 502 is activated by the controller. The glue pump 502 draws glue from the glue storage tank 5, and the glue flows through the glue extraction tube 501 and the glue outlet hose 503 into the connecting pipe 3 and the feed pipe 208. It then enters the space between pistons b207 and a204 inside the transparent glue spray tube 2, and flows onto the plywood from multiple glue spray holes 210. As the drive roller 104 and driven roller 105 rotate, the plywood moves to the conveyor mechanism for the next process. When the plywood leaves the top of the drive roller 104 and driven roller 105, the soft bristles at the bottom of the brush 109 apply glue to the top of the plywood, covering it with glue.

[0041] Furthermore, when the spraying is completed and the adhesive inside the transparent spray tube 2 needs to be cleaned to prevent it from solidifying, the threaded cap 202 is screwed on so that one end of the threaded cap 202 is completely unscrewed from one side of the transparent spray tube 2, and the threaded cap 202 is pulled to move the piston a204, scraper 206 and piston b207 outward. At this time, the scraper 206 can scrape out the adhesive remaining inside the transparent spray tube 2 to clean the adhesive inside the transparent spray tube 2.
