Description

Technical Field

[0001] This invention belongs to the field of acrylic sheet cleaning technology, specifically an acrylic sheet cleaning mechanism. Background Technology

[0002] Acrylic is a general term for acrylic and methacrylic chemicals. Acrylic sheets are polymerized from methyl methacrylate monomers and possess excellent physical and chemical properties such as high transparency and resistance to acids and alkalis. During production, acrylic sheets are typically cut and processed according to usage requirements. This process generates a large amount of dust that adheres to the acrylic sheet. When further finishing processes such as bonding are required, residual dust can hinder the even adhesion of the adhesive, reducing bond strength. During printing and spraying, it can cause defects such as pinholes, particles, and orange peel, leading to a lower product yield.

[0003] After acrylic sheets are cut, they are usually rinsed to clean them. However, this method can easily leave white scale or spots on the acrylic sheets after they dry, creating new pollution. This secondary pollution can also affect the quality of subsequent bonding and spraying.

[0004] Therefore, in order to solve the above problems, an acrylic sheet cleaning mechanism is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides an acrylic sheet cleaning mechanism, which solves the problem that white scale or spots are left on acrylic sheets after rinsing with water, forming new pollution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an acrylic sheet cleaning mechanism, comprising a support frame, an acrylic sheet, and a plurality of guide rollers equidistantly mounted thereon, wherein side frames are mounted on both sides of the support frame, and further comprising: two sets of cleaning mechanisms mounted on the side frames, wherein the two sets of cleaning mechanisms are respectively located above and below the acrylic sheet; wherein the acrylic sheet is placed on the guide rollers; The cleaning mechanism includes a fixed scraper, a movable scraper, and a spray nozzle mounted on a side frame. The movable scraper is movably mounted on the side frame, and an arc-shaped plate is fixedly connected to one end of the movable scraper. A set of power motors is fixedly connected to one of the side frames, and a cam is fixedly connected to the output end of the power motors. A spring is fixedly sleeved on the movable scraper to support the movement of the arc-shaped plate toward the cam. Rotating the cam can push the arc-shaped plate to move. The support frame is equipped with a feeding mechanism for moving the acrylic sheet.

[0007] Preferably, the cleaning mechanisms located above and below the acrylic plate are vertically offset, with the lower cleaning mechanism located downstream of the upper cleaning mechanism.

[0008] Preferably, one end of each of the two sets of moving scrapers is fixedly connected to the same T-shaped pipe, and both ends of the spray pipe are respectively movably sleeved on the two sets of side frames. A set of plate-shaped parts is provided in the middle of the spray pipe, and one side of the plate-shaped parts can be fixedly connected to one side of the moving scraper.

[0009] Preferably, sponge strips are provided on both the upper and lower surfaces of the acrylic sheet; The side of the sponge strip away from the acrylic sheet is a plastic sheet, and a set of tension spring combination rods are symmetrically fixed to the plastic sheet. One end of the tension spring combination rod passes through the plate-shaped part and is movably sleeved inside it. The tension spring part of the tension spring combination rod is used to pull the tension spring combination rod and make it tend to move towards the acrylic sheet.

[0010] Preferably, the support frame is equipped with a storage mechanism for storing acrylic sheets, and the feeding mechanism can send the acrylic sheets in the storage mechanism into the cleaning mechanism.

[0011] Preferably, a set of base frames are symmetrically fixed to the bottom of the support frame; The storage mechanism comprises four sets of side plates movably mounted on the support frame and located upstream of the cleaning mechanism. Each set of side plates on the same side of the support frame has several equidistant one-way slots. The bottom ends of the four sets of side plates are connected as a whole by a bracket, and a tension member is fixedly connected between the bracket and the base frame. A spring-loaded combination block is movably mounted on the support frame. The spring-loaded combination block tends to move towards the side plate, and one end of the spring-loaded combination block can be engaged in the one-way slot. A crossbar is fixedly connected to the spring-loaded combination block, and the other end of the crossbar can be fixedly connected to one end of another spring-loaded combination block. When the side plate moves downwards, it can squeeze the spring-loaded combination block through the one-way slot and disengage it. A set of limiting rods is also fixedly connected to the support frame, and the acrylic plate can be placed between the two limiting rods; The minimum distance between the bottom of the limiting stop and the outer perimeter of the guide roller is greater than the thickness of one acrylic sheet but less than the thickness of two acrylic sheets.

[0012] Preferably, the top of the side plate is provided with an inclination angle, and the inclined surface of the top of the side plate faces inward.

[0013] Preferably, the feeding mechanism includes a push plate slidably mounted on the support frame and located upstream of the storage mechanism. The top of the push plate is rotatably connected to a plurality of support rollers at equal intervals. The bottom of the base frame is fixedly connected to an electric telescopic cylinder in an extended state. The output end of the electric telescopic cylinder can be fixedly connected to the end of the push plate away from the storage mechanism.

[0014] Preferably, a set of unidirectional damping mechanisms for decelerating the side plates when they move upwards is symmetrically arranged at the bottom of the base frame.

[0015] Preferably, the unidirectional damping mechanism includes a connecting rod hinged to the bottom of the base frame, a damping bearing is provided at the bottom end of the connecting rod, the inner ring of the damping bearing is fixedly connected to the bottom end of the connecting rod, a rubber wheel is fixedly connected to the outer ring of the damping bearing, and a tension spring is fixedly connected between the lower surface of the base frame and the connecting rod; the outer periphery of the rubber wheel contacts the side plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The above solution uses a feeding mechanism to push the acrylic sheet into the cleaning mechanism. During the movement, the acrylic sheet is first sprayed with cleaning liquid from the spray nozzle. At the same time, the motor drives the cam to rotate and squeeze the arc-shaped plate. At this time, the moving scraper moves. When the protrusion on the arc-shaped plate disengages from the arc-shaped plate, the arc-shaped plate is pushed back to its original position by the spring force. With the high-speed rotation of the motor, the moving scraper performs high-frequency reciprocating motion, thereby achieving efficient cleaning of the acrylic sheet surface. After the motor passes the moving scraper, the fixed scraper will further clean the acrylic sheet surface, further improving the cleaning effect and preventing white scale or spots from being left on the acrylic sheet surface. The above solution involves stacking several acrylic sheets and placing them on a support frame, thereby limiting the acrylic sheets between two sets of limit bars. When the electric telescopic cylinder retracts, it drives the support rollers to move towards the acrylic sheets and pushes the bottom acrylic sheet towards the cleaning mechanism. The stacked acrylic sheets are kept in place by the support rollers. When the electric telescopic cylinder extends and drives the push plate to reset, the bottom acrylic sheet in the stack will fall onto the base frame to facilitate the next operation of the device, thereby improving the working efficiency of the device. The above solution involves pressing down on the side plate when replenishing the acrylic sheet, causing the spring combination blocks to engage in the one-way slots and the tensioning component to stretch and store force. This allows the operator to place the acrylic sheet on the guide rollers from the side and stack them with gaps. After stacking, the operator pulls the crossbar outward, causing the two sets of spring combination blocks to move outward and release the lock on the one-way slots. Under the pulling force of the tensioning component, the side plate will move upward, thereby limiting the stacked acrylic sheet. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 9 As shown, the present invention provides an acrylic sheet cleaning mechanism, including a support frame 1, an acrylic sheet 4, and a plurality of guide rollers 11 equidistantly mounted thereon. Side frames 12 are mounted on both sides of the support frame 1. The mechanism also includes two sets of cleaning mechanisms 2 mounted on the side frames 12, with the two sets of cleaning mechanisms 2 located above and below the acrylic sheet 4, respectively. The acrylic sheet 4 is placed on the guide rollers 11. The cleaning mechanism 2 includes a fixed scraper 21, a movable scraper 22, and a spray nozzle 26 mounted on a side frame 12. The movable scraper 22 is movably mounted on the side frame 12, and an arc-shaped plate 23 is fixedly connected to one end of the movable scraper 22. A set of power motors 24 is fixedly connected to one of the side frames 12, and a cam 25 is fixedly connected to the output end of the power motors 24. A spring 221 for supporting the movement of the arc-shaped plate 23 toward the cam 25 is fixedly sleeved on the movable scraper 22. Rotating the cam 25 can push the arc-shaped plate 23 to move. A feeding mechanism 6 for pushing the acrylic plate 4 to move is mounted on the support frame 1. Using the above scheme, the acrylic sheet 4 is pushed into the cleaning mechanism 2 by the feeding mechanism 6. During the movement, the acrylic sheet 4 is first sprayed with cleaning liquid from the spray nozzle 26. At the same time, the power motor 24 drives the cam 25 to rotate and squeeze the arc plate 23. At this time, the moving scraper 22 moves. When the protrusion on the arc plate 23 is out of contact with the arc plate 23, the arc plate 23 is pushed back to its original position by the elastic force of the spring 221. With the high-speed rotation of the power motor 24, the moving scraper 22 will perform high-frequency reciprocating motion, thereby achieving efficient cleaning of the surface of the acrylic sheet 4. After the surface of the power motor 24 passes the moving scraper 22, the fixed scraper 21 will further clean the surface of the acrylic sheet 4, further improving the cleaning effect of the acrylic sheet 4 and avoiding the occurrence of white scale or spots on the surface of the acrylic sheet 4.

[0021] like Figures 3-5 As shown, the cleaning mechanisms 2 located above and below the acrylic plate 4 are misaligned in the vertical direction, and the cleaning mechanism 2 located below is downstream of the cleaning mechanism 2 above. By adopting the above solution, by placing the lower cleaning mechanism 2 downstream of the upper cleaning mechanism 2, the cleaning liquid sprayed by the upper cleaning mechanism 2 is prevented from flowing to the lower surface of the acrylic plate 4.

[0022] like Figures 3-6 As shown, one end of each of the two sets of moving scrapers 22 is fixedly connected to the same three-way pipe 261. Both ends of the spray pipe 26 are movably sleeved on the two sets of side frames 12 respectively. A set of plate-shaped parts 262 is provided in the middle of the spray pipe 26. One side of the plate-shaped parts 262 can be fixedly connected to one side of the moving scraper 22. Sponge strips 3 are provided on the upper and lower surfaces of the acrylic sheet 4 respectively; the side of the sponge strip 3 away from the acrylic sheet 4 is a plastic sheet, and a set of tension spring combination rods 31 are symmetrically fixed on the plastic sheet. One end of the tension spring combination rod 31 passes through the plate-shaped part 262 and is movably sleeved inside it. The tension spring part of the tension spring combination rod 31 is used to pull the tension spring combination rod 31 and make it tend to move towards the acrylic sheet 4. By adopting the above scheme, the spray nozzle 26 is movably sleeved on the side frame 12 and moves synchronously with the moving scraper 22 through the plate-shaped part 262, so that the cleaning liquid sprayed out is more uniform. At the same time, the movement of the spray nozzle 26 will also drive the sponge strip 3 to move, so that the sponge strip 3 first cleans the dust and other particles attached to the acrylic plate 4, and then the moving scraper 22 and the fixed scraper 21 scrape them off, which further improves the cleaning effect of the device on the acrylic plate 4.

[0023] like Figures 1-3 and Figures 7-9 As shown, a storage mechanism 5 for storing acrylic sheets 4 is installed on the support frame 1, and the feeding mechanism 6 can send the acrylic sheets 4 in the storage mechanism 5 into the cleaning mechanism 2; a set of base frames 13 are symmetrically fixed to the bottom of the support frame 1. The storage mechanism 5 consists of four sets of side plates 51 movably mounted on the support frame 1 and located upstream of the cleaning mechanism 2. Each set of side plates 51 on the same side of the support frame 1 has several equidistant one-way slots 52. The bottom ends of the four sets of side plates 51 are connected as a whole by a bracket, and a tension member 55 is fixedly connected between the bracket and the base frame 13. A spring combination block 53 is movably mounted on the support frame 1. The spring combination block 53 has a tendency to move towards the side plate 51, and one end of the spring combination block 53 can be inserted into the one-way slot 52. A crossbar 54 is fixedly connected to the spring combination block 53, and the other end of the crossbar 54 can be fixedly connected to one end of another spring combination block 53. When the side plate 51 moves downwards, it can squeeze the spring combination block 53 through the one-way slot 52 and disengage it. A set of limiting rods 14 are also fixedly connected to the support frame 1, and the acrylic plate 4 can be placed between two limiting rods 14; the minimum distance between the bottom of the limiting rod 14 and the outer periphery of the guide roller 11 is greater than the thickness of one acrylic plate 4 and less than the thickness of two acrylic plates 4; the top of the side plate 51 is provided with an inclination angle, and the inclined surface of the top of the side plate 51 faces inward. The feeding mechanism 6 includes a push plate 61 that is slidably mounted on the support frame 1 and located upstream of the storage mechanism 5. Several support rollers 63 are rotatably connected at equal intervals to the top of the push plate 61. An electric telescopic cylinder 62 in an extended state is fixedly connected to the bottom of the base frame 13. The output end of the electric telescopic cylinder 62 can be fixedly connected to the end of the push plate 61 away from the storage mechanism 5.

[0024] Using the above scheme, several acrylic sheets 4 are stacked and placed on the support frame 1, so that the acrylic sheets 4 are limited between two sets of limit bars 14. When the electric telescopic cylinder 62 operates and retracts, it can drive the support roller 63 to move towards the acrylic sheet 4 and push the bottom acrylic sheet 4 towards the cleaning mechanism 2. The stacked acrylic sheets 4 will be kept in place by the support of the support roller 63. When the electric telescopic cylinder 62 extends and drives the push plate 61 to reset, the acrylic sheet 4 at the bottom of the stack will fall onto the base frame 13 to facilitate the next operation of the device, thereby improving the working efficiency of the device. It is worth noting that when supplementing acrylic sheet 4, pressing down on side plate 51 causes spring combination blocks 53 to engage in one-way slots 52 and pull force member 55 to stretch and store force. At this time, it is convenient for the operator to place acrylic sheet 4 on guide roller 11 from the side and stack them with gaps. After stacking, the operator pulls the crossbar 54 outward and drives the two sets of spring combination blocks 53 to move outward and release the lock on one-way slot 52. Under the action of the pull force member 55, the side plate 51 will be driven upward, thereby limiting the stacked acrylic sheet 4.

[0025] like Figure 8 and Figure 9 As shown, a set of one-way damping mechanisms 7 for decelerating the side plate 51 when it moves upward is symmetrically arranged at the bottom of the base frame 13. The one-way damping mechanism 7 includes a connecting rod 71 hinged to the bottom of the base frame 13. A damping bearing 72 is provided at the bottom end of the connecting rod 71. The inner ring of the damping bearing 72 is fixedly connected to the bottom end of the connecting rod 71. A rubber wheel 73 is fixedly connected to the outer ring of the damping bearing 72. A tension spring 74 is fixedly connected between the lower surface of the base frame 13 and the connecting rod 71. The outer periphery of the rubber wheel 73 contacts the side plate 51. With the above solution, when the side plate 51 moves upward, it will also contact the rubber wheel 73 and drive the rubber wheel 73 to have an upward trend. At this time, the presence of the damping bearing 72 will have a deceleration effect on the rubber wheel 73, thereby avoiding the situation where the side plate 51 moves upward too fast. When the side plate 51 moves downward, it will cause the rubber wheel 73 to rotate downward. At this time, the connecting rod 71 will deflect, and the contact pressure between the rubber wheel 73 and the side plate 51 will decrease, thereby preventing the damping bearing 72 from affecting the rapid downward reset of the side plate 51.

[0026] Working principle and usage process of this invention: The acrylic sheet 4 is pushed into the cleaning mechanism 2 by the feeding mechanism 6. During the movement, the acrylic sheet 4 is first sprayed with cleaning liquid from the spray nozzle 26. At the same time, the power motor 24 drives the cam 25 to rotate and squeeze the arc plate 23. At this time, the moving scraper 22 moves. When the protrusion on the arc plate 23 is separated from the arc plate 23, the arc plate 23 is pushed back to its original position under the action of the spring force 221. With the high-speed rotation of the power motor 24, the moving scraper 22 will perform high-frequency reciprocating motion, thereby achieving efficient cleaning of the surface of the acrylic sheet 4. After the surface of the power motor 24 passes the moving scraper 22, the fixed scraper 21 will further clean the surface of the acrylic sheet 4, further improving the cleaning effect of the acrylic sheet 4 and avoiding the occurrence of white scale or spots on the surface of the acrylic sheet 4. The operator can stack several acrylic sheets 4 and place them on the support frame 1, so that the acrylic sheets 4 are limited between two sets of limit bars 14. When the electric telescopic cylinder 62 retracts, it can drive the support roller 63 to move towards the acrylic sheet 4 and push the bottom acrylic sheet 4 towards the cleaning mechanism 2. The stacked acrylic sheets 4 will be kept in place by the support of the support roller 63. When the electric telescopic cylinder 62 extends and drives the push plate 61 to reset, the acrylic sheet 4 at the bottom of the stack will fall onto the base frame 13 for the next operation of the device. When the operator needs to replenish the acrylic sheet 4, pressing down on the side plate 51 causes the spring combination block 53 to engage in the one-way slot 52, and the tension member 55 to stretch and store force. At this time, it is convenient for the operator to place the acrylic sheet 4 on the guide roller 11 from the side and stack them with gaps. After stacking, the operator pulls the crossbar 54 outward and drives the two sets of spring combination blocks 53 to move outward and release the lock on the one-way slot 52. Under the action of the tension member 55, the side plate 51 will be driven upward, thereby limiting the stacked acrylic sheet 4.
