Description

Technical Field

[0001] The present invention belongs to the technical field of floor gluing, and specifically relates to a back glue coating device for SPC floor installation. Background Art

[0002] SPC floor is a new type of environmentally friendly floor, which is made of stone powder, polyvinyl chloride (PVC) and other materials through high temperature and high pressure. Its structure usually includes four layers. SPC floor back glue coating refers to coating a layer of glue on the back of the SPC (stone plastic composite) floor so that it can be firmly bonded to the ground or other substrates during installation. Back glue coating is one of the key steps in the SPC floor installation process, and its quality directly affects the bonding strength and service life of the floor. Back glue coating is usually completed by automated equipment to ensure uniform and efficient gluing.

[0003] For example, the utility model with the publication number CN209985681U discloses a floor gluing device, including: a bracket; a conveyor belt, which is arranged on the bracket for transporting the substrate; two glue leakage boxes, each of which is provided with a plurality of spaced-apart glue leakage holes at one end facing the conveyor belt. The width of the glue leakage box is equal to the width of the substrate. The two glue leakage boxes are respectively movably arranged above the conveyor belt along the length direction of the conveyor belt and there is a gap between them and the conveyor belt; two glue tanks, which are respectively arranged on the bracket and are respectively connected to the two glue leakage boxes; a plurality of glue pipes, one ends of the plurality of glue pipes are respectively connected to the glue leakage boxes, and the other ends are respectively connected to the glue tanks; a manipulator, which is telescopically arranged above the conveyor belt for clamping the LTV layer; a control system, which is connected to the conveyor belt, the glue tank and the manipulator to control the working states of the conveyor belt, the glue tank and the manipulator. According to the floor gluing device of the present invention, the gluing time is shortened, and the connection between the substrate and the LTV layer is made firm.

[0004] The back glue coating equipment in the above device is prone to problems such as uneven glue distribution during the gluing process. Due to the uneven surface or the presence of dust on the plate, it is easy to cause problems such as the glue applied on the plate surface being concentrated or dispersed. At the same time, the micropores on the surface of the gluing roller are unevenly distributed or the pore diameters are inconsistent, which is likely to cause unstable glue outflow, resulting in too much or too little glue in some parts. When the glue amount is too much, it will cause glue overflow, increasing the cleaning difficulty and wasting materials at the same time. When the glue amount is too little, it will cause the floor to be not firmly bonded, affecting the installation quality.

[0005] Therefore, a back glue coating device for SPC floor installation is proposed to solve the problems raised in the background art. Summary of the Invention

An electric push rod fixedly connected to the vertical plate is fixedly arranged on the side surface of the moving arm.

[0013] Preferably, both of the two clamping plates are U-shaped, and a support plate is fixedly connected to the side close to the moving block. The support plate is triangular and in contact with the bottom of the board.

[0014] Preferably, a sleeve rod is sleeved at the center of the screw rod. The threads on the symmetric two sides of the screw rod are opposite, and the two moving blocks are respectively located on both sides of the sleeve rod.

[0015] Preferably, the grinding assembly includes a grinding roller located on one side of the top of the conveyor belt near the clamping plate, fixing brackets rotatably arranged symmetrically on both sides of the center of the grinding roller, and a grinding motor fixedly arranged on one side of the fixing brackets for driving the grinding roller to rotate.

[0016] Preferably, both symmetrical sides of the connecting frame are fixedly connected with connecting plates, and electric cylinders fixedly connected to the support platform are fixedly arranged at the bottoms of the two connecting plates.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] Through the cooperation of structures such as a conveyor belt, a flattening mechanism, etc. and a gluing mechanism, the present invention facilitates the grinding and dust cleaning of the board. The clamping component clamps and fixes the board on the conveyor belt to ensure its stability during the grinding process. After fixation, the grinding component descends and grinds the surface of the board to eliminate surface unevenness. After grinding, the clamping component releases the board, allowing it to fall back onto the conveyor belt and continue to be transported. During the transportation process, the dust cleaning component cleans the dust generated by grinding the surface of the board to ensure a clean surface. The cleaned board enters the gluing mechanism, and uniform gluing is achieved through precise control, further improving the gluing quality, and solving the problem that the existing gluing equipment has uneven glue distribution during gluing due to dust or unevenness on the surface and uneven distribution of glue outlet holes, affecting the bonding quality of the board. Through the cooperation of structures such as clamping plates, grinding rollers, and electric push rods, the present invention facilitates the fixed grinding of the board. The clamping component clamps and fixes the board, providing a stable support for subsequent grinding operations. The adjustment motor drives the screw to rotate. Since the thread directions on both sides of the screw are opposite, the moving blocks on both sides will move towards each other along the moving arms when rotating. When the board is transported to the position of the clamping component, the two moving blocks approach each other, pushing the clamping plates on both sides to approach synchronously, causing the board to slide along the support plate at the bottom of the clamping plate and be fixed on the support plate, completing the clamping operation, improving the stability of the board fixation, and providing a reliable basis for subsequent grinding. After grinding, the clamping plates move to both sides, releasing the board, allowing it to fall back onto the conveyor belt and continue to be transported.

[0023] Through the cooperation of structures such as a first winding roller, a second winding roller, an alcohol skin, and an installation box, the present invention facilitates the cleaning of dust on the surface of the board. When the board is polished and then transported to the dust cleaning component through the conveyor belt, it can be wiped through the first winding roller at the position of the through groove at the bottom of the dust cleaning component with the alcohol cotton sheet on its surface. After wiping, in order to avoid the dust on the side of the alcohol cotton sheet close to the board affecting the dust cleaning effect, the first adjustment block can be rotated to drive the first winding roller to rotate, thereby driving the alcohol cotton sheet on the first winding roller to be wound up, and at the same time transferring the relatively clean alcohol cotton sheet on the second winding roller at the top to the first winding roller for subsequent dust cleaning.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 8 shown, the present invention provides a back glue coating device for SPC floor installation, including a conveyor belt 1, mounting frames 11 fixedly arranged on both symmetrical sides of the conveyor belt 1, a control motor 12 fixedly installed on the mounting frames 11 for driving the conveyor belt 1 to operate, and a plate 3 placed on the conveyor belt 1, and further includes:

[0035] A support platform 2, the support platform 2 is located at the bottom of the mounting frame 11, support frames 21 are fixedly arranged at the four corners of the bottom of the support platform 2, and vertical plates 22 fixedly connected to the bottom of the mounting frame 11 are fixedly arranged on both symmetrical sides of the support platform 2;

[0036] The flattening mechanism 4 is located at the top of the conveyor belt 1 and is used to sand and clean the plate 3.

[0037] The gluing mechanism 5 is located on one side of the top of the conveyor belt 1 away from the flattening mechanism 4.

[0038] Among them, the flattening mechanism 4 includes a clamping component 41 arranged on the support platform 2 for clamping the plate 3, a grinding component 42 located on the top of the clamping component 41 for grinding the plate 3, a connecting frame 43 installed on the top of the grinding component 42, and a dust cleaning component 44 arranged on the side of the connecting frame 43 away from the grinding component 42 for cleaning the dust on the surface of the plate 3.

[0039] Adopting the above solution: During use, the plate 3 to be glued is placed on the conveyor belt 1 and transmitted along the conveyor belt 1. During the transmission process, the flattening mechanism 4 and the gluing mechanism 5 are used in cooperation to achieve grinding, dust removal and gluing of the plate 3, avoiding the problem of uneven gluing caused by the uneven surface of the plate 3. First, the clamping component 41 is used to clamp and fix the plate 3 on the conveyor belt 1. After fixing, the grinding component 42 descends to grind it. After grinding, the plate 3 is released and falls back onto the conveyor belt 1 for transmission. During the transmission process, the dust cleaning component 44 is used to clean the dust ground on its surface. The cleaned plate 3 is reasonably glued through the gluing mechanism 5.

[0040] As Figure 7 shown, the clamping component 41 includes two clamping plates 411 symmetrically arranged on both sides of the conveyor belt 1 and in contact with the plate 3, moving blocks 412 fixedly installed at the bottoms of the two clamping plates 411, a moving arm 413 slidably arranged on the top of the support platform 2 and slidably connected to the two moving blocks 412, a screw rod 414 screwed on the two moving blocks 412 and rotatably connected to both sides of the moving arm 413, and an adjusting motor 415 fixedly arranged on one side of the moving arm 413 for driving the screw rod 414 to rotate. An electric push rod 45 fixedly connected to the vertical plate 22 is fixedly arranged on the side surface of the moving arm 413.

[0041] Both of the two clamping plates 411 are U-shaped, and a support plate 4111 is fixedly connected to the side close to the moving block 412. The support plate 4111 is triangular and in contact with the bottom of the plate 3. A sleeve rod 416 is sleeved at the center of the screw rod 414. The threads on the symmetric two sides of the screw rod 414 are opposite, and the two moving blocks 412 are respectively located on both sides of the sleeve rod 416.

[0042] Adopt the above scheme: By using the clamping assembly 41 to clamp and fix the plate 3, it is convenient for reasonable grinding. The adjusting motor 415 drives the screw 414 to rotate. Since the threads on both sides of the screw 414 are opposite, during the rotation, the moving blocks 412 on both sides move towards each other along the moving arm 413. When the plate 3 is transported to one side of the clamping assembly 41, the two moving blocks 412 approach each other, thereby driving the clamping plates 411 on both sides to approach each other, causing the plate 3 to slide onto the support plate 4111 at the bottom of the clamping plate 411 and being clamped simultaneously, thus improving the stability of the fixation of the plate 3 and facilitating subsequent grinding. After grinding is completed, the clamping plate 411 is moved to both sides to release the plate 3 so that it falls into the conveyor belt 1 for continuous transportation.

[0043] As Figure 2 shown, the grinding assembly 42 includes a grinding roller 421 located on one side of the top of the conveyor belt 1 close to the clamping plate 411, fixed frames 422 rotatably arranged symmetrically on both sides of the center of the grinding roller 421, and a grinding motor 423 fixedly arranged on one side of the fixed frame 422 for driving the grinding roller 421 to rotate. The top of the grinding motor 423 is fixedly connected to the connecting frame 43;

[0044] Both symmetrical sides of the connecting frame 43 are fixedly connected with connecting plates 431, and electric cylinders 432 fixedly connected to the support platform 2 are fixedly arranged at the bottoms of the two connecting plates 431.

[0045] Adopt the above scheme: During grinding, the electric cylinder 432 drives the grinding roller 421 to approach the plate 3, and at the same time, the grinding motor 423 drives the grinding roller 421 to rotate to grind the surface of the plate 3. To ensure uniform grinding, the electric push rod 45 pushes the moving arm 413 to move along the top of the support platform 2, driving the clamping plate 411 and the fixed plate 3 to slide synchronously, so that the grinding roller 421 can evenly cover the surface of the plate 3. After grinding is completed, the grinding motor 423 is turned off to end the grinding operation.

[0046] As Figure 8 shown, the dust cleaning assembly 44 includes a first winding roller 441, a second winding roller 442 located directly above the first winding roller 441, an alcohol cotton sheet 443 wound around the first winding roller 441 and the second winding roller 442, and an installation box 444 rotatably connected to both ends of the first winding roller 441 and the second winding roller 442;

[0047] Both the first winding roller 441 and the second winding roller 442 penetrate through the mounting box 444. One end of each of the first winding roller 441 and the second winding roller 442 is fixedly provided with a first adjusting block 4411 and a second adjusting block 4421 respectively. A through groove 4441 for accommodating the first winding roller 441 and the alcohol cotton sheet 443 is formed at the bottom of the mounting box 444. A closing cover plate 4442 is hinged on the side surface of the mounting box 444. With the above solution: After the sheet 3 is polished, it is conveyed to the dust cleaning assembly 44 through the conveyor belt 1. The first winding roller 441 is provided at the position of the through groove 4441 at the bottom of the dust cleaning assembly 44, and its surface is covered with the alcohol cotton sheet 443 for wiping and cleaning the surface of the sheet 3. During the wiping process, in order to prevent the side of the alcohol cotton sheet 443 close to the sheet 3 from being affected by dust accumulation and affecting the dust cleaning effect, the first adjusting block 4411 can be rotated to drive the first winding roller 441 to rotate, the used alcohol cotton sheet 443 is wound up, and at the same time, the clean alcohol cotton sheet 443 on the top second winding roller 442 is transferred to the first winding roller 441 to ensure the subsequent dust cleaning effect. After the equipment is used up, the closing cover plate 4442 can be opened, and the alcohol cotton sheet 443 wound on the first winding roller 441 and the second winding roller 442 is removed, replaced and re-wound with a new alcohol cotton sheet 443 for the next use, which improves the dust cleaning efficiency, is also convenient for maintenance and replacement of cleaning materials, and ensures the long-term stable operation of the equipment.

[0048] As Figure 4 shown, the gluing mechanism 5 includes a glue outlet box 51 fixedly arranged on one side of the bottom of the connecting frame 43 away from the clamping plate 411 and a scraping plate 52 fixedly arranged on one side of the glue outlet box 51 close to the mounting box 444. A plurality of glue outlet ports 511 arranged in a linear array are fixedly provided at the bottom of the glue outlet box 51. A glue inlet port 512 for adding glue is fixedly provided at the top of the scraping plate 52. The bottom of the scraping plate 52 is triangular.

[0049] With the above solution: By using the gluing mechanism 5, when the sheet 3 moves to the bottom of the glue outlet box 51, the glue inside the glue outlet box 51 is dripped onto the surface of the sheet 3 along the glue outlet ports 511, and at the same time, the scraping plate 52 is used to scrape the glue on the surface of the sheet 3 flat, thereby avoiding the problem of uneven glue application.

[0050] Working principle and usage process of the present invention: When using this device, first place the plate 3 to be coated with glue on the conveyor belt 1 and let it be transported along the conveyor belt 1. Start the adjustment motor 415 to drive the screw 414 to rotate, and then drive the moving blocks 412 on both sides to move towards each other along the moving arm 413. When the plate 3 is transported to the clamping assembly 41, the two moving blocks 412 approach each other, driving the clamping plates 411 on both sides to approach synchronously, so that the plate 3 slides down along the triangular support plate 4111 at the bottom of the clamping plate 411 and is fixed on the support plate 4111 to complete the clamping operation. After clamping, use the grinding motor 423 to drive the grinding roller 421 to rotate to grind the plate 3. During the grinding process, the electric push rod 45 pushes the moving arm 413 to move along the top of the support platform 2, driving the clamping plate 411 and the fixed plate 3 to slide synchronously to ensure uniform grinding of the surface of the plate 3. After grinding, loosen the clamping plate 411 to make the plate 3 fall back onto the conveyor belt 1 and continue to be transported. During the transportation process, the plate 3 passes through the dust cleaning assembly 44 for wiping and cleaning. The cleaned plate 3 continues to be transported to the gluing area. The glue in the glue outlet box 51 evenly drips onto the surface of the plate 3 through the glue outlet 511, and at the same time, the scraper 52 cooperates to scrape the glue flat to ensure uniform gluing, realizing the integrated operation of automatic clamping, grinding, cleaning, and gluing of the plate 3, improving the processing efficiency and quality.
