Description

Technical Field

[0001] This application relates to the field of thermal insulation board processing, and particularly to a thermal insulation board forming machine for a refrigerated box. Background Art

[0002] The thermal insulation board of a refrigerated box belongs to a composite board, and the thermal insulation board has different composite structures. One manufacturing process for the thermal insulation board used to manufacture a heat insulation box is as follows: stack in sequence according to the order of a fiberglass layer, a glass paper layer, a polyurethane foam layer, a glass paper layer, and a fiberglass layer. The plates are all cubes, and adjacent plates are bonded by an adhesive to form a plate to be formed, and the plate to be processed is then subjected to hot pressing treatment by a hot press to form a thermal insulation board.

[0003] The hot press includes a frame, a support plate, and a hot pressing plate. The support plate and the hot pressing plate are parallel to each other. The support plate is fixedly arranged at the lower end of the frame, and the hot pressing plate is slidably connected to the upper end of the frame and faces the support plate. The frame is fixedly provided with a heating component for heating the hot pressing plate, and the frame is provided with a driving component for driving the hot pressing plate to press down. After placing the plate to be formed on the support plate, the driving component is used to drive the hot pressing plate to press down, so that the hot pressing plate and the support plate cooperate to press the plate to be formed tightly, and the heating component is synchronously started to heat the hot pressing plate, thereby performing hot pressing on the plate to be formed.

[0004] Regarding the above related technology, when the hot press performs hot pressing on the plate to be processed, the adhesive between the plates is easily overflowed along the side edges to the periphery of the plates under the action of pressure. After the adhesive overflows on the side edges of the thermal insulation board, it is easily cured quickly during hot pressing, and then adheres to the side edges of the thermal insulation board and is not easy to remove, affecting the quality of the thermal insulation board. Therefore, manual wiping is usually used, and the manual wiping efficiency is low. Summary of the Invention

[0005] In order to facilitate the removal of the adhesive overflowing during the hot pressing of the thermal insulation board, this application provides a thermal insulation board forming machine for a refrigerated box.

[0006] This application provides a thermal insulation board forming machine for a refrigerated box, adopting the following technical solutions:

[0007] A heat preservation board forming machine for a refrigerator includes a hot press body. The hot press body includes a frame and a support plate and a hot press plate arranged inside the frame. The support plate is fixedly connected to the frame, and the hot press plate is slidably connected to the frame. A plurality of cleaning components are arranged along the circumference of the support plate, and a moving component for driving the cleaning components to move towards the heat preservation board is provided. The cleaning component includes a moving plate, a driving member, a moving member, and two cleaning plates. The moving plate is slidably connected to the upper end surface of the support plate. A sliding groove is formed in the moving plate along its length direction. The moving member is slidably connected to the moving plate along its length direction. The driving member is arranged at the end of the moving plate and is used to drive the moving member to slide along the moving plate. A connecting groove is formed at one end of the moving member away from the moving plate. The two cleaning plates are both rotatably connected to the connecting groove and are symmetric to each other. The cleaning plate is provided with an abutting surface that fits against the plate to be processed. An elastic member I corresponding to the cleaning plate is arranged in the connecting groove. The two elastic members I have a tendency to drive the abutting surfaces of the two cleaning plates to approach each other. Abutting blocks are fixedly arranged at one end of the moving member away from the moving plate. The abutting blocks are located between the two cleaning plates, and both sides of the abutting blocks are abutted against the two cleaning plates respectively.

[0008] By adopting the above technical solution, the plate to be processed is placed on the support plate. The moving component drives the cleaning component to approach the side of the heat preservation board, so that the moving plate drives the moving member to approach the heat preservation board. The moving member drives the two cleaning plates to contact the side of the plate to be processed at the same time. The abutting blocks limit the two cleaning plates, so that the ends of the two cleaning plates away from the moving member are in an open state. Then, when the two cleaning plates approach the plate to be processed, the plate to be processed pushes the two cleaning plates to rotate and squeezes the elastic member I. Under the elastic force of the elastic member I, the abutting surface of the cleaning plate fits against the side of the plate to be processed. The hot press plate is used to hot press the plate to be processed. The driving member drives the moving member to move along the length direction of the moving plate. Then, when the plate to be processed is hot pressed, the adhesive overflowing from the side is cleaned by the cleaning plate. Therefore, there is no need to clean manually again after hot pressing, and it is more convenient to remove the adhesive overflowing during the hot pressing of the heat preservation board.

[0009] Optionally, the moving component includes a fixed plate, a motor I, a bidirectional threaded rod, two sliding members, and two swing rods. The fixed plate is fixedly connected to the support plate. The motor I is fixedly connected to one end of the fixed plate. A through groove is formed in the fixed plate along its length direction. The two sliding blocks are both slidably connected to the through groove and are in contact with the inner wall of the through groove. A connecting ring is fixedly arranged at one end of the sliding block away from the moving plate. The bidirectional threaded rod is coaxially and fixedly connected to the output shaft of the motor I. The bidirectional threaded rod includes a first threaded portion and a second threaded portion with a spiral direction opposite to that of the first threaded portion. The first threaded portion passes through the connecting ring close to the motor I and is threadedly connected to it. The second threaded portion passes through the connecting ring away from the motor I and is threadedly connected to it. One ends of the two swing rods are respectively hinged to the two sliding blocks, and the other ends of the two swing rods are both hinged to the moving plate.

[0010] By adopting the above technical solution, the fixing plate supports the sliding member, so that the sliding block moves along the length direction of the fixing plate under the limiting action of the through groove. The first motor drives the bidirectional threaded rod to rotate, so that the first threaded portion and the second threaded portion drive the two connecting rings to move synchronously, and the moving directions are opposite. The two connecting rings drive the two sliding blocks to move respectively, so that the two sliding blocks drive the two swing rods to swing. When the swing rods swing, they push the moving plate closer to or away from the plate to be processed.

[0011] Optionally, stop plates are fixedly connected to both ends of the moving plate. Scrapers are rotatably connected to the sides of the two stop plates close to each other. The scrapers are located at the ends of the stop plates away from the moving plate. An elastic member II is provided between the stop plate and the scraper. The elastic member II has a tendency to pull the scraper to fit with the stop plate. A limiting block is fixedly connected to the position of the stop plate where the elastic member II is provided, and the limiting block abuts against the scraper.

[0012] By adopting the above technical solution, the stop plate abuts against the side of the plate to be processed, and then the plate to be processed is positioned by the stop plate. The limiting block limits the scraper, so that there is a certain gap between the scraper and the stop plate. When the moving member moves to the end of the moving plate, the end of the cleaning plate is inserted into the gap. When the moving member continues to move, the cleaning plate pushes the scraper to rotate, and the elastic member II drives the scraper to abut against the side of the cleaning plate away from the plate to be processed, so that the scraper cleans the adhesive adhered to the cleaning plate.

[0013] Optionally, a card slot is formed in the abutting block. A wiping plate is slidably connected in the card slot. The wiping plate fits with the inner wall of the card slot. A rubber layer is fixedly provided at the end of the wiping plate away from the abutting block.

[0014] By adopting the above technical solution, the rubber layer fits with the side of the heat preservation plate, and the inner wall of the card slot limits the wiping plate, so that when the moving block moves, the wiping plate is driven to move by the abutting block, and then the side of the heat preservation plate is wiped and cleaned by the rubber layer, which is beneficial to further cleaning the adhesive overflowing from the side of the heat preservation plate.

[0015] Optionally, a second motor is fixedly provided at the lower end of the support plate. A lead screw is fixedly connected to the output shaft of the second motor. A sliding plate slides at the lower end of the support plate. The lead screw passes through the sliding plate and is threadedly connected thereto. A receiving groove is formed at one end of the support plate close to the second motor. A push plate is slidably connected in the receiving groove. A discharge port is formed at the end of the support plate away from the receiving groove. A cylinder is fixedly provided at the lower end of the support plate. The output end of the cylinder passes through the support plate and abuts against the push plate. First sliding rods are fixedly provided at both ends of the push plate. The support plate is provided with sliding grooves adapted to the first sliding rods. Moving blocks adapted to the first sliding rods are fixedly provided at both ends of the sliding plate. The two first sliding rods are respectively inserted into the corresponding moving blocks and slidably connected thereto.

[0016] By adopting the above technical solution, in the initial state, the push plate is located in the receiving groove, so that there is no interference between the push plate and the moving plate. After the hot pressing is completed, the moving plate resets, the output end of the cylinder extends to push the push plate out of the receiving groove, the second motor drives the screw rod to rotate, so that the screw rod pushes the sliding plate to move. When the sliding plate moves, the first sliding rod is driven to move along the sliding groove through the moving block, and then the push plate is driven to move along the upper end surface of the support plate, so that the adhesive residue cleaned by the cleaning plate is discharged from the discharge port by the push plate. After the cleaning is completed, the second motor drives the push plate to move above the receiving groove, so that the push plate abuts against the output end of the cylinder, and the output end of the cylinder retracts. Under the action of gravity, the push plate sinks into the receiving groove.

[0017] Optionally, the moving block is provided with a cavity, the first sliding rod is located in the cavity and is slidably connected to the inner wall of the cavity. A return spring is arranged in the cavity. One end of the return spring is fixedly connected to the first sliding rod, and the other end is fixedly connected to the moving block. The return spring is in a stretched state and has a tendency to pull the push plate closer to the sliding plate.

[0018] By adopting the above technical solution, when the push plate moves along the upper end surface of the support plate, the return spring exerts a downward pulling force on the first sliding rod, so that the first sliding rod has a tendency to move downward along the inner wall of the cavity, making the push plate fit more closely with the support plate, which is beneficial to improving the cleaning effect of the push plate.

[0019] Optionally, baffle plates are fixedly arranged at both ends of the push plate, and arc surfaces are arranged at the joints of the baffle plates and the push plate.

[0020] By adopting the above technical solution, the baffle plates are beneficial to reducing the probability of the adhesive residue slipping from both ends of the push plate, and the arc surfaces are beneficial to aggregating the adhesive waste, which is convenient for cleaning.

[0021] Optionally, a plurality of baffle plates are fixedly arranged along the circumference at the lower end of the hot pressing plate. The baffle plates are provided with relief openings adapted to the swing rods. The swing rods are slidably connected in the relief openings and are in contact with the inner walls of the relief openings. The lower end surfaces of the baffle plates are in contact with the support plate.

[0022] By adopting the above technical solution, the hot pressing plate, the support plate and all the baffle plates cooperate to form a cavity. During hot pressing, the plate to be processed is inside the cavity, and the swing rod is in contact with the inner wall of the relief opening, so that the cavity is sealed, which is beneficial to reducing the diffusion of the heat of the hot pressing plate during hot pressing, improving the hot pressing efficiency and saving energy.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] The board to be processed is placed on the support board. The cleaning component is driven by the moving component to approach the side of the insulation board. Then, the moving plate drives the moving part to approach the insulation board, and the moving part drives the two cleaning boards to contact the side of the board to be processed simultaneously. The abutting block limits the two cleaning boards, so that the ends of the two cleaning boards away from the moving part are in an open state. Then, when the two cleaning boards approach the board to be processed, the board to be processed pushes the two cleaning boards to rotate and compress the first elastic part. Under the elastic force of the first elastic part, the contact surface of the cleaning board fits against the side of the board to be processed. The board to be processed is hot-pressed by the hot pressing plate. The driving part drives the moving part to move along the length direction of the moving plate. Then, when the board to be processed is hot-pressed, the adhesive overflowing from the side is cleaned by the cleaning board. Thus, it is not necessary to clean manually again after hot pressing, and it is more convenient to remove the adhesive overflowing during the hot pressing of the insulation board;

[0025] The fixing plate supports the sliding part, so that the sliding block moves along the length direction of the fixing plate under the limiting action of the through groove. The first motor drives the bidirectional threaded rod to rotate. Then, the first threaded part and the second threaded part drive the two connecting rings to move synchronously, and the moving directions are opposite. The two connecting rings drive the two sliding blocks to move respectively, so that the two sliding blocks drive the two swing rods to swing. When the swing rods swing, they push the moving plate to approach or move away from the board to be processed;

[0026] The stop plate abuts against the side of the board to be processed, and then the board to be processed is positioned by the stop plate. The limiting block limits the scraping plate, so that there is a certain gap between the scraping plate and the stop plate. When the moving part moves to the end of the moving plate, the end of the cleaning board inserts into the gap. When the moving part continues to move, the cleaning board pushes the scraping plate to rotate, and the second elastic part drives the scraping plate to abut against the side of the cleaning board away from the board to be processed. Thus, the scraping plate cleans the adhesive adhered to the cleaning board. Description of the Drawings

Detailed implementation manners

[0035] The following further elaborates on this application in detail with reference to all the attached drawings.

[0036] The embodiment of this application discloses a forming machine for thermal insulation boards used in refrigerators.

[0037] Referring to Figure 1 , a forming machine for thermal insulation boards used in refrigerators includes a hot press body, and the hot press body includes a frame 1, a support plate 2, and a hot pressing plate 3. The hot pressing plate 3 is parallel to the support plate 2, the support plate 2 is horizontally arranged at the lower end of the frame 1 and fixedly connected to the frame 1. The hot pressing plate 3 is arranged at the upper end of the frame 1, the hot pressing plate 3 is slidably connected to the frame 1, the frame 1 is equipped with a driving device 11 for driving the hot pressing plate 3 to move up and down, and the frame 1 is equipped with a heating assembly for heating the hot pressing plate 3.

[0038] Referring to Figure 1 and Figure 2 , an operator places the plate to be processed 10 on the upper end surface of the support plate 2. The support plate 2 is provided with multiple groups of cleaning assemblies 4 and moving assemblies 5 corresponding to the cleaning assemblies 4 in a circumferential direction. The cleaning assembly 4 includes a moving plate 41, a driving member 42, a moving member 43, and two cleaning plates 44. The moving plate 41 is slidably connected to the upper end surface of the support plate 2 and is opposite to the side of the plate to be processed 10, and the moving member 43 is located on the side of the moving plate 41 close to the plate to be processed 10.

[0039] Referring to Figure 2and Figure 3 A sliding groove 415 is formed in the moving plate 41 along the length direction. One end of the moving member 43 is slidably connected to the sliding groove 415 and is in contact with the inner wall of the sliding groove 415. The driving member 42 is installed at one end of the moving plate 41. The driving member 42 includes a second motor 421 and a threaded push rod 422. The second motor 421 is fixedly connected to the moving plate 41. The output shaft of the second motor 421 penetrates through the moving plate 41 and is rotatably connected thereto. The threaded push rod 422 is rotatably connected to the sliding groove 415, and the threaded push rod 422 penetrates through the moving member 43 and is threadedly connected thereto. The output shaft of the second motor 421 is coaxially fixed to the threaded push rod 422. When the output shaft of the second motor 421 rotates, it drives the threaded push rod 422 to rotate, so that the threaded push rod 422 pushes the moving member 43 to move.

[0040] Refer to Figure 3 and Figure 4 As shown in FIGS. and, the cleaning plates 44 are each provided with an abutting surface 441 corresponding to the plate 10 to be processed. The abutting surface 441 is a flat surface. The two cleaning plates 44 are arranged oppositely, and the abutting surfaces 441 of the two cleaning plates 44 are close to each other. The cleaning plate 44 is fixedly provided with a connecting rod 442, and the two connecting rods 442 are parallel to each other. A connecting groove 431 is formed at one end of the moving member 43 away from the moving plate 41. The connecting rod 442 is located in the connecting groove 431 and is rotatably connected to the inner wall of the connecting groove 431.

[0041] Refer to Figure 3 and Figure 4 As shown in FIGS. and, a first elastic member 432 corresponding to the connecting column is provided in the connecting groove 431. The first elastic member 432 is a torsion spring. One end of the torsion spring is fixedly connected to the moving member 43, and the other end is fixedly connected to the connecting column. The torsion springs are all in a twisted state and have a tendency to drive the two cleaning plates 44 to rotate, so that the two abutting surfaces 441 are close to each other. An abutting block 433 is fixed to one end of the moving member 43 away from the moving plate 41. The abutting block 433 is arranged vertically. The abutting block 433 is located between the two cleaning plates 44. The two cleaning plates 44 are both in contact with the abutting block 433. The abutting block 433 restricts the two abutting surfaces 441 from approaching each other, so that the ends of the two cleaning plates 44 away from the moving member 43 are in a separated state.

[0042] Refer to Figure 2, the moving component 5 includes a fixing plate 51, a first motor 52, a bidirectional threaded rod 53, two sliding members 54 and two swing rods 55. The fixing plate 51 is circumferentially fixed along the support plate 2, and a through groove 511 is circumferentially provided on the fixing plate 51. Both sliding members 54 are slidably connected within the through groove 511, and the two sliding members 54 are evenly arranged. The first motor 52 is installed at one end of the fixing plate 51, and the first motor 52 is located at the end of the fixing plate 51 away from the plate to be processed 10. The bidirectional threaded rod 53 includes a first threaded portion 531 and a second threaded portion 532. The spiral directions of the first threaded portion 531 and the second threaded portion 532 are opposite and coaxial with each other. The first threaded portion 531 is coaxially fixed with the output shaft of the first motor 52. When the output shaft of the first motor 52 rotates, it drives the bidirectional threaded rod 53 to rotate.

[0043] Refer to Figure 2 , the sliding member 54 is in contact with the inner wall of the through groove 511. A connecting ring 541 is fixed to the end of the sliding member 54 away from the plate to be processed 10. The first threaded portion 531 passes through the connecting ring 541 of the sliding block close to the first motor 52 and is threadedly connected thereto. The second threaded portion 532 passes through the connecting ring 541 of the sliding member 54 away from the first motor 52 and is threadedly connected thereto. When the bidirectional threaded rod 53 rotates, the first threaded portion 531 and the second threaded portion 532 respectively drive the two connecting rings 541 to move, thereby driving the two sliding members 54 to move synchronously and in opposite directions along the through groove 511.

[0044] Refer to Figure 2 , the two swing rods 55 correspond to the two sliding members 54 respectively. One end of the swing rod 55 is hinged to the end of the corresponding sliding block away from the connecting ring 541, and the other end is hinged to the moving plate 41. When the two sliding blocks move, they drive the swing rods 55 to swing, so that the swing rods 55 push the moving plate 41 closer to the plate to be processed 10.

[0045] Refer to Figure 2 and Figure 3 , during the process of the moving plate 41 approaching the side of the plate to be processed 10, the cleaning plate 44 abuts against the plate to be processed 10. The plate to be processed 10 pushes the two cleaning plates 44 to rotate outward around the abutting block 433. Stop plates 411 are fixedly connected to both ends of the moving plate 41. When the stop plates 411 abut against the plate to be processed 10, the abutting surfaces 441 of the cleaning plates 44 are in contact with the plate to be processed 10. The stop plates 411 on all the moving plates 41 cooperate to limit the plate to be processed 10, which is beneficial to positioning the plate to be processed 10.

[0046] Refer to Figure 2 and Figure 5 , the actuating drive device 11 (refer to Figure 1) drives the hot pressing plate 3 to press down. The hot pressing plate 3 is fixedly connected with a baffle 31 along the circumferential direction. The baffle 31 is provided with a clearance opening 311 adapted to the swing rod 55. The baffle 31 is gradually pressed down and contacts the support plate 2. At this time, the swing rod 55 is located in the clearance opening 311. All baffles 31 are between the hot pressing plate 3 and the baffle 31. The output shaft of the motor 2 421 rotates, thereby driving the moving part 43 to move along the length direction of the moving plate 41. The moving plate 41 drives the cleaning plate 44 to clean the side of the to-be-processed plate 10. There is no need to manually clean the to-be-processed plate 10 again after hot pressing. It is more convenient to remove the adhesive overflowed during the hot pressing of the to-be-processed plate 10.

[0047] Reference Figure 3 and Figure 6 The two stop plates 411 at both ends of the same moving plate 41 are both provided with a scraper 412 at the ends close to each other. One end of the scraper 412 is rotatably connected to the corresponding stop plate 411, and the other end is in a free moving state. The free moving end of the scraper 412 approaches the end of the stop plate 411 away from the moving plate 41. The stop plate 411 is fixed with a limiting block 413, and the limiting block 413 is in conflict with the scraper 412, so that the end of the scraper 412 is in contact with the plate to be processed 10 (refer to Figure 2 A second elastic member 414 is fixed between the stop plate 411 and the scraper 412. The second elastic member 414 is configured as a tension spring. One end of the tension spring is fixedly connected to the stop plate 411, and the other end is fixedly connected to the scraper 412. The tension spring is in a stretched state and has a tendency to pull the movable end of the scraper 412 closer to the stop plate 411.

[0048] Reference Figure 3 and Figure 6 When the cleaning plate 44 moves to the side end of the plate to be processed 10, the side of the cleaning plate 44 enters the gap. The scraper 412 is in contact with the end of the cleaning plate 44 away from the abutting surface 441, and the cleaning plate 44 continues to move, so that the scraper 412 moves along the side of the cleaning plate 44 away from the abutting surface 441. The scraper 412 cleans the adhesive attached to the cleaning plate 44, which is conducive to maintaining the cleaning effect of the cleaning plate 44.

[0049] Reference Figure 3The abutment block 433 is provided with a slot 434 vertically, the lower end of the slot 434 does not penetrate the abutment block 433, and a wiper plate 435 is slidably connected in the slot 434, and the wiper plate 435 is in contact with the inner wall of the slot 434. A rubber layer 436 is fixed to the end of the wiper plate 435 away from the abutment block 433, and the rubber layer 436 is in contact with the side of the plate 10 to be processed. The abutment block 433 drives the wiper plate 435 to move through the slot 434, so that the rubber layer 436 cleans the side of the plate 10 to be processed, which is conducive to further improving the cleaning effect of the adhesive overflowing from the side of the plate 10 to be processed. The operator moves the wiper plate 435 upward to remove it from the slot 434, so that it is more convenient to replace the wiper plate 435.

[0050] Reference Figure 1 The lower end of the support plate 2 is equipped with a motor 3 21, and the output shaft of the motor 3 21 is coaxially fixed with a screw rod 22. When the output shaft of the motor 3 21 rotates, the screw rod 22 is driven to rotate. The lower end of the support plate 2 is provided with a sliding plate 23. The support plate 2 is fixed with a plurality of second sliding rods parallel to the screw rod 22. The second sliding rods penetrate the sliding plate 23 and are slidably connected with the sliding plate 23. The second sliding rods limit the sliding plate 23 so that the sliding plate 23 moves along the length direction of the second sliding rods. The screw rod 22 penetrates the sliding plate 23 and is threadedly connected with the sliding plate 23. When the screw rod 22 rotates, the sliding plate 23 is driven to move.

[0051] Reference Figure 2 and Figure 7 The upper end surface of the support plate 2 is provided with a receiving groove 25, which is located at one end of the support plate 2 where the motor 3 21 is installed. A push plate 24 is slidably connected in the receiving groove 25, and the push plate 24 is in contact with the inner wall of the receiving groove 25. Both ends of the push plate 24 are fixed with a first slide bar 241, which is vertically downwardly arranged. The support plate 2 is moved along the screw rod 22 (refer to Figure 1 ) A sliding groove 28 is provided in the length direction, and the first sliding rod 241 passes through the sliding groove 28 and fits with the inner wall of the sliding groove 28. The inner wall of the sliding groove 28 limits the first sliding rod 241, so that the first sliding rod 241 slides along the length direction of the sliding groove 28.

[0052] Reference Figure 2 and Figure 7 After the hot pressing is completed, the operator moves the hot pressing plate 3 upward, removes the hot pressing insulation plate, and operates the motor 52 to drive the corresponding moving plate 41 to return to its original position. The adhesive waste cleaned by the cleaning plate 44 falls on the upper end surface of the support plate 2. There is a certain gap between the lower end of the moving plate 41 and the support plate 2, which is conducive to reducing the probability of the moving plate 41 moving the adhesive waste.

[0053] Reference Figure 1 and Figure 2, a cylinder 27 is installed at the lower end of the support plate 2. The cylinder 27 is located directly below the accommodation cavity. The output end of the cylinder 27 penetrates through the support plate 2 and is slidably connected to the support plate 2. The output end of the cylinder 27 abuts against the lower end of the push plate 24. The operator manipulates the output end of the cylinder 27 to push the push plate 24 upward, so that the lower end surface of the push plate 24 is on the same horizontal plane as the upper end surface of the support plate 2. Moving blocks 231 are fixed at both ends of the sliding plate 23 along the length direction. The moving blocks 231 correspond one by one to the first sliding rods 241 (refer to Figure 7 ). The first sliding rods 241 are inserted into the corresponding moving blocks 231, and the first sliding rods 241 (refer to Figure 7 ) are slidably connected to the moving blocks 231. The moving blocks 231 limit the first sliding rods 241 (refer to Figure 7 ), so that the sliding plate 23 drives the first sliding rods 241 (refer to Figure 7 ) to move through the moving blocks 231.

[0054] Refer to Figure 1 and Figure 2 , when the first sliding rods 241 (refer to Figure 7 ) move, they drive the push plate 24 to move. Under the action of gravity, the push plate 24 fits against the upper end surface of the support plate 2. Thus, when the push plate 24 moves, it cleans the adhesive waste on the upper end surface of the support plate 2. A discharge port 26 is provided at one end of the upper end surface of the support plate 2 away from the accommodation groove 25. The push plate 24 pushes the adhesive waste into the discharge port 26 for discharge.

[0055] Refer to Figure 1 and Figure 2 , baffle plates 242 are fixed at both ends of the push plate 24. The baffle plates 242 block both ends of the push plate 24, which helps to reduce the probability of the adhesive waste slipping from both sides of the push plate 24. An arc surface 243 is provided at the connection between the push plate 24 and the baffle plates 242. When the push plate 24 drives the adhesive waste to move, the waste moves along the arc surface 243, which helps to aggregate the waste, and thus facilitates the discharge of the waste from the discharge port 26.

[0056] Refer to Figure 2 and Figure 7 , a cavity 232 is formed in the moving block 231. The end of the first sliding rod 241 away from the sliding plate 23 is located in the cavity 232. A return spring 233 is provided in the cavity 232. Both ends of the return spring 233 are fixedly connected to the first sliding rod 241 and the moving block 231 respectively. The return spring 233 is in a stretched state, and thus pulls the push plate 24 to fit against the support plate 2 through the first sliding rod 241, which helps to further improve the cleaning effect of the push plate 24 on the support plate 2. After the cleaning is completed, the cylinder 27 (refer to Figure 1 ) drives the push plate 24 to reset, so that the push plate 24 abuts against the output end of the cylinder 27 (refer to Figure 1 ). Manipulate the cylinder 27 (refer toFigure 1 )The output end is recycled. Under the action of gravity and the pulling force of the return spring 233, the push plate 24 sinks into the receiving groove 25, so that there is no interference between the push plate 24 and the moving plate 41.

[0057] The implementation principle of a thermal insulation board forming machine for a refrigerator in an embodiment of the present application is as follows: Place the to-be-treated board 10 on the support plate 2, drive the moving plate 41 to approach the side of the to-be-treated board 10 through the first motor 52, and position the to-be-treated board 10 through the stop plate 411. The moving plate 41 drives the two cleaning plates 44 to abut against the side of the to-be-treated board 10. Under the limiting action of the abutting block 433, the two cleaning plates 44 open, so that during the process of the cleaning plates 44 approaching the to-be-treated board 10. The to-be-treated board 10 pushes the two cleaning plates 44 to rotate and away from the limiting block 413. When the cleaning plates 44 rotate, the torsion springs are compressed, so that the torsion springs have a tendency to drive the cleaning plates 44 to approach the side of the to-be-treated board 10. At this time, the abutting surface 441 of the cleaning plates 44 fits against the side of the to-be-treated board 10. Operate the hot pressing plate 3 to perform hot pressing on the to-be-treated board 10, and operate the second motor 421 to drive the moving member 43 to move, so that the moving plate 41 drives the cleaning plates 44 to clean the adhesive overflowing from the side of the to-be-treated board 10 during hot pressing, which is beneficial to reducing the time spent on manually cleaning the adhesive on the side of the thermal insulation board, and it is more convenient to remove the adhesive overflowing during hot pressing of the to-be-treated board 10.

[0058] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
