Description

Technical Field

[0001] The invention relates to the technical field of polyurethane foam board production, and in particular to automatic production equipment and method for polyurethane foam boards. Background Art

[0002] Polyurethane foam board is a new type of synthetic material with thermal insulation and waterproof functions. Due to its low thermal conductivity, it is mainly used in building exterior wall insulation, cold storage insulation, pipe insulation, building panels, refrigerated trucks and cold storage insulation materials, etc.

[0003] When producing polyurethane foam boards, black and white materials are first injected into the foaming machine and mixed to obtain foaming raw materials. The raw materials are then sent to a uniformly moving surface material for foaming. At the same time, the upper surface material is folded onto the foam plastic, and finally a polyurethane foam composite board with surface materials on both the top and bottom is produced. The surface materials are mostly made of aluminum foil or metal materials. During the foaming and transmission process, the polyurethane foam matures in the double-layer pressurized panel. After that, the board only needs to be cut to the required length to produce the polyurethane foam composite board of the required specifications.

[0004] During production, foam boards of different thicknesses need to be manufactured according to demand, so the distance between the two surface materials needs to be adjusted. At the same time, after the foam board is produced, it needs to be trimmed, and the excess surface material at the beginning of the matching part needs to be trimmed, which causes great waste. Therefore, we propose an automatic production equipment and method for polyurethane foam boards. Summary of the Invention

[0006] A bottom plate, and a groove plate arranged on the top of the bottom plate, wherein holes are opened on both sides of the groove plate;

[0007] a conveying mechanism disposed inside the groove plate, and a column disposed at the bottom of the conveying mechanism;

[0008] A loading assembly having a hybrid structure and a support frame disposed on top of the groove plate;

[0009] A lifting assembly having an unwinding structure for placing an aluminum plate on top of the foam plate, and a connecting block provided on the side of the lifting assembly close to the loading assembly;

[0010] The top of the base plate is fixedly connected to the bottom of the groove plate, the column is fixedly connected to the top of the base plate, the side of the column away from the base plate is fixedly connected to the bottom of the conveying mechanism, the support frame is fixedly connected to the side of the groove plate away from the base plate, the inner side of the groove plate is fixedly connected to the surface of the loading assembly, the connecting block is arranged at the interval between the lifting assembly and the loading assembly, and the two sides of the surface of the connecting block are respectively fixedly connected to the sides of the lifting assembly and the loading assembly close to each other;

[0011] Wherein, the feeding assembly includes:

[0012] A foaming machine having a mixing structure for mixing white material and black material, and a telescopic tube arranged on the top of the foaming machine;

[0013] a bent pipe, the bent pipe being bent toward a side close to the lifting assembly and being used for pouring foam on the top of the aluminum plate;

[0014] A sprue, the end of which is away from the elbow and is arranged parallel to the bottom plate, and a casting plate arranged at the end of the sprue away from the elbow;

[0015] The foaming machine is arranged inside the groove plate, and the side of the foaming machine close to the lifting assembly is fixedly connected to the surface of the connecting block, and the side of the foaming machine away from the bottom plate is provided with a telescopic tube, and one end of the telescopic tube away from the foaming machine extends to the top of the groove plate, and the surface of the telescopic tube is fixedly connected to the inner wall of the groove plate, and the surface of the telescopic tube located on the outside of the groove plate is fixedly connected to the inner side surface of the support frame, and the side of the foaming machine away from the telescopic tube is fixedly connected to the side of the bent pipe away from the bottom plate, and one end of the bent pipe away from the foaming machine is fixedly connected to the side of the material head away from the bottom plate, and one end of the material head away from the bent pipe is fixedly connected to the surface of the casting plate, and the black material and the white material are injected into the telescopic tube and then enter the interior of the foaming machine to complete the mixing of the black and white materials to form a foamed material, and the aluminum plate is placed on the top of the conveying mechanism, and the conveying mechanism drives the aluminum plate The other aluminum plate is wound on the lifting assembly, and then the raw materials inside the foaming machine enter the inside of the elbow, and then enter the inside of the material head, and finally flow out from the casting plate, pouring the foaming material on the top of the aluminum plate below. Then the two aluminum plates are combined, the foaming material expands and solidifies, and the production of the foam board is completed. With the transportation of the conveying mechanism, foam boards are continuously formed to complete the automatic production of the polyurethane foam board. Since the elbow is bent to the side close to the lifting assembly, that is, it is bent close to the position of the two aluminum plates, the foaming material is poured into the gap between the two aluminum plates as much as possible. After the production is completed, the cutting of the aluminum plate is minimized to avoid waste of the aluminum plate. The material head is parallel to the conveying mechanism, and the casting plate is also parallel to the conveying mechanism, that is, parallel to the bottom aluminum plate. During pouring, the distribution of the foaming raw materials is more even, thereby forming a foamed board with more uniform density.

[0016] Furthermore, a plurality of nozzles are fixedly connected to the side of the casting plate away from the material head, a connecting plate is fixedly connected to the surface of the material head, a telescopic rod is fixedly connected to the side of the connecting plate away from the material head, and one end of the telescopic rod away from the connecting plate is fixedly connected to the inner side surface of the groove plate. When the telescopic rod is started, the connecting plate with the telescopic rod moves, thereby driving the material head to move, deforming the bent pipe, and at the same time driving the casting plate to reciprocate, cooperating with the conveying mechanism to perform reciprocating casting on the top of the aluminum plate. During the reciprocating casting, the casting plate moves, and a layer of foaming material is poured on the top of the aluminum plate. , the pouring plate is reset, and the aluminum plate moves forward at the same time, and another layer of foaming material is poured. The foaming material is thickened layer by layer to avoid gaps and voids caused by excessive pouring at one time, which can make the pouring of the foaming material more complete. With the movement of the conveying mechanism and the telescopic rod, the foam board can be poured more evenly. The setting of several nozzles can pour a larger area at one time, thereby improving the pouring efficiency. The latter nozzle fills the gap poured by the previous nozzle, which can further fill the gaps and voids poured in the previous time to obtain a more complete foam board.

[0017] Furthermore, the conveying mechanism includes a plate body, which is symmetrically arranged on the top of the base plate, and the two plates are fixedly connected to the top of the column on one side close to the base plate. A conveying roller is provided at the interval between the two plates, and the two ends of the conveying roller are rotatably connected to the side of the two plates close to each other, and there are several conveying rollers, as well as a transmission assembly arranged at the end of the conveying roller. The transmission assembly drives several conveying rollers to rotate, and the aluminum plate is placed on the top of the conveying roller, and then the conveying roller drives the aluminum plate. After pouring and combining with another aluminum plate, the foam board is conveyed.

[0018] Furthermore, the surface of the conveying roller is provided with grooves, and the grooves of the conveying roller are arranged in a threaded shape, and the threaded grooves of adjacent conveying rollers are arranged in opposite directions. The grooves on the surface of the conveying roller can increase the friction between the conveying roller and the aluminum plate, thereby preventing the aluminum plate from slipping and ensuring smooth transportation. The threaded grooves can increase the range of the grooves within a limited length, thereby obtaining a better conveying effect. The threaded grooves of adjacent conveying rollers are in opposite directions, which can provide opposite forces to the aluminum plate and offset each other, thereby enhancing the conveying effect while preventing the threaded grooves from causing the aluminum plate to tilt.

[0019] Furthermore, the transmission assembly includes a rotating shaft, and there are several rotating shafts, and the surface of the rotating shaft is rotatably connected to the inner side surface of the conveying roller. The two ends of several rotating shafts respectively pass through the two plate bodies, and the surface of the rotating shaft is rotatably connected to the inner side surface of the plate body. Conveyor belts are symmetrically arranged on both sides of the two plate bodies, and the inner side surface of the conveyor belt is transmission-connected to several rotating shafts. Driving one rotating shaft to rotate drives the conveyor belt to transmit, thereby driving all the remaining rotating shafts to rotate, thereby driving the conveying rollers to rotate synchronously, ensuring smooth transportation of the foam board.

[0020] Furthermore, a mounting plate is fixedly connected to the side of the plate away from the conveying roller, a motor is fixedly connected to the surface of the mounting plate, and the output end of the motor is fixedly connected to the end of the rotating shaft. When the motor is started, the output end of the motor drives a rotating shaft to rotate.

[0021] Furthermore, the lifting assembly includes a telescopic column, which is fixedly connected to the side of the groove plate close to the bottom plate, and the side of the telescopic column away from the groove plate is fixedly connected to the sleeve plate, and the side of the sleeve plate away from the telescopic column is fixedly connected to the mounting seat, and the surface of the mounting seat is fixedly connected to the side of the connecting block away from the foaming machine, and the side of the mounting seat away from the sleeve plate is rotatably connected to the reel, and an aluminum plate is wound around the surface of the reel. When the telescopic column is started, the telescopic column drives the sleeve plate, the mounting seat and the reel to rise and fall, thereby adjusting the distance between the two aluminum plates, thereby achieving the purpose of adjusting the thickness of the foam plate.

[0022] Furthermore, the two plates are fixedly connected with a threaded column on one side away from the bottom plate, and the surface of the threaded column is threadedly connected with a sleeve, and the threaded column is fixedly connected with a limiting column on the other side away from the plate body, and the limiting column is arranged inside the sleeve, and the surface of the limiting column is slidably connected with a supporting column, and the surface of the support column is slidably connected to the inner wall of the sleeve. The sleeve is rotated and the sleeve rotates on the surface of the threaded column, thereby adjusting the height and limiting the height of the mounting seat, avoiding the difficulty in controlling the telescopic distance of the telescopic column, ensuring the adjustment of the thickness of the foam board, and avoiding damage to the foam board caused by excessive telescopic distance.

[0023] Furthermore, springs are provided inside and outside the sleeve, the spring located inside the sleeve is sleeved on the outside of the limit column, and the spring is fixedly connected to the side of the support column close to the threaded column, and the spring located outside the sleeve is sleeved on the outside of the support column, and the spring is fixedly connected to the side of the sleeve away from the threaded column, the mounting seat contacts the support column, and the support column slides inside the sleeve, thereby driving the two springs to deform, buffering the movement of the support column, avoiding excessive impact on the mounting seat, avoiding deformation of the aluminum plate wound on the reel, and avoiding affecting the quality of the foam board, the limiting column and the support column slide relative to each other, and the setting of the limiting column can limit the support column, avoid tilting of the support column, and ensure the support effect.

[0024] A method for using an automatic polyurethane foam board production device comprises the following steps:

[0025] Step 1: Install the aluminum plate. Place one aluminum plate on the top of the conveyor roller and wind the other aluminum plate around the reel. Then rotate the sleeve so that it rotates on the surface of the threaded column to adjust the height, limit the height of the mounting seat, and control the thickness of the foam plate. Start the telescopic column, which drives the sleeve, mounting seat, and reel to rise and fall, thereby adjusting the distance between the two aluminum plates and adjusting the thickness of the foam plate.

[0026] Step 2: Aluminum plate buffering. The mounting base contacts the support column, and the support column slides inside the sleeve, thereby causing the two springs to deform and buffer the movement of the support column.

[0027] Step 3: Injecting raw materials: inject the black material and the white material into the telescopic tube, and then enter the foaming machine to complete the mixing of the black and white materials to form foamed materials. At the same time, the mounting seat moves, driving the connecting block to move, driving the foaming machine to move, and the telescopic tube expands and contracts to complete the production of foamed materials.

[0028] Step 4: Foam board forming. Start the motor. The output end of the motor drives a rotating shaft to rotate, which drives the conveyor belt to drive, thereby driving all the remaining rotating shafts to rotate, thereby driving the conveyor rollers to rotate synchronously. The conveyor rollers drive the aluminum plate. At the same time, the raw materials inside the foaming machine enter the inside of the elbow, then enter the inside of the material head, and finally flow out of the casting plate. The foaming material is poured on the top of the aluminum plate below. The two aluminum plates are combined, and the foaming material expands and solidifies, completing the production of the foam board.

[0029] Step 5: Reciprocating pouring. Start the telescopic rod. The connecting plate of the telescopic rod moves, thereby driving the material head to move and the elbow to deform. At the same time, it drives the pouring plate to reciprocate. Cooperate with the conveying mechanism to reciprocate pouring on the top of the aluminum plate, and pour the foam board more evenly.

[0030] The present invention has the beneficial effects:

[0031] The present invention completes the production of foam boards by setting a feeding component, and the foaming material expands and solidifies, and with the transportation of the conveying mechanism, the foam boards are continuously formed, thereby completing the automatic production of the polyurethane foam boards. Since the elbow is bent toward the side close to the lifting component, that is, bent close to the position of the two aluminum plates, the foaming material is poured into the gap between the two aluminum plates as much as possible. After the production is completed, the cutting of the aluminum plates is minimized to avoid waste of the aluminum plates. The material head is parallel to the conveying mechanism, and the pouring plate is also parallel to the conveying mechanism, that is, parallel to the bottom aluminum plate. During pouring, the distribution of the foaming raw materials is more uniform, thereby forming a foam board with more uniform density.

[0032] The present invention provides a conveying roller with grooves on the surface of the conveying roller, which can increase the friction between the conveying roller and the aluminum plate, thereby preventing the aluminum plate from slipping and ensuring smooth conveying. The threaded grooves can increase the range of the grooves within a limited length, thereby obtaining a better conveying effect. The threaded grooves of adjacent conveying rollers are in opposite directions, which can provide opposite forces for the aluminum plate and offset each other. While enhancing the conveying effect, it can avoid the aluminum plate from tilting due to the threaded grooves.

[0033] The present invention sets a lifting component, and the telescopic column drives the sleeve plate, the mounting seat, and the reel to rise and fall, thereby adjusting the distance between the two aluminum plates to achieve the purpose of adjusting the thickness of the foam board. The sleeve is rotated, and the sleeve rotates on the surface of the threaded column to adjust the height, and the height of the mounting seat is limited to avoid the telescopic distance of the telescopic column being difficult to control, ensuring the adjustment of the thickness of the foam board, and avoiding damage to the foam board caused by excessive telescopic distance.

[0034] The present invention provides a support column, the mounting seat contacts the support column, and the support column slides inside the sleeve, thereby driving the two springs to deform, cushioning the movement of the support column, preventing the mounting seat from being subjected to excessive impact, preventing the aluminum plate wound on the reel from being deformed, and avoiding affecting the quality of the foam board. The limiting column slides relative to the support column, and the setting of the limiting column can limit the support column, avoid the support column from tilting, and ensure the supporting effect.

[0052] Among them, the feeding component 5 includes:

[0053] A foaming machine 51 having a mixing structure for mixing white material and black material, and a telescopic tube 52 provided on the top of the foaming machine 51;

[0054] A bent pipe 53, which is bent toward a side close to the lifting assembly 7 and is used to pour foam on the top of the aluminum plate;

[0055] a sprue 54, the end of which is away from the elbow 53 and is arranged parallel to the bottom plate 1, and a casting plate 55 arranged at the end of the sprue 54 away from the elbow 53;

[0056] The foaming machine 51 is arranged inside the groove plate 2, and the side of the foaming machine 51 close to the lifting component 7 is fixedly connected to the surface of the connecting block 8, and a telescopic tube 52 is provided on the side of the foaming machine 51 away from the bottom plate 1, and one end of the telescopic tube 52 away from the foaming machine 51 extends to the top of the groove plate 2, and the surface of the telescopic tube 52 is fixedly connected to the inner wall of the groove plate 2, and the surface of the telescopic tube 52 located on the outside of the groove plate 2 is fixedly connected to the inner side of the support frame 6, and the side of the foaming machine 51 away from the telescopic tube 52 is fixedly connected to the side of the elbow 53 away from the bottom plate 1, and the end of the elbow 53 away from the foaming machine 51 is fixedly connected to the side of the material head 54 away from the bottom plate 1, and the end of the material head 54 away from the elbow 53 is fixedly connected to the surface of the casting plate 55, and the black material and the white material are injected into the telescopic tube 52 and then enter the foaming machine 51 to complete the mixing of the black and white materials to form a foamed material, and the aluminum plate is placed on the top of the conveying mechanism 3 and conveyed. The mechanism 3 drives the aluminum plate to be transported, and the other aluminum plate is wound on the lifting component 7. Then the raw material inside the foaming machine 51 enters the inside of the curved pipe 53, and then enters the inside of the material head 54, and finally flows out from the casting plate 55, pouring the foaming material on the top of the aluminum plate below. Then the two aluminum plates are combined, the foaming material expands and solidifies, and the production of the foam board is completed. With the transportation of the conveying mechanism 3, the foam board is continuously formed, and the automatic production of the polyurethane foam board is completed. Since the curved pipe 53 is bent to the side close to the lifting component 7, that is, it is bent close to the position of the two aluminum plates, the foaming material is poured into the gap between the two aluminum plates as much as possible. After the production is completed, the cutting of the aluminum plate is minimized to avoid waste of the aluminum plate. The material head 54 is parallel to the conveying mechanism 3, and the casting plate 55 is also parallel to the conveying mechanism 3, that is, parallel to the bottom aluminum plate. During pouring, the distribution of the foaming raw material is more uniform, thereby forming a foam board with more uniform density.

[0057] The side of the pouring plate 55 away from the material head 54 is fixedly connected to a plurality of nozzles, the surface of the material head 54 is fixedly connected to a connecting plate 57, the side of the connecting plate 57 away from the material head 54 is fixedly connected to a telescopic rod 56, and one end of the telescopic rod 56 away from the connecting plate 57 is fixedly connected to the inner side of the groove plate 2. When the telescopic rod 56 is started, the connecting plate 57 brought by the telescopic rod 56 moves, thereby driving the material head 54 to move, the elbow 53 to deform, and at the same time driving the pouring plate 55 to reciprocate, cooperating with the conveying mechanism 3 to reciprocate pouring on the top of the aluminum plate. During the reciprocating pouring, the pouring plate 55 moves, and the top of the aluminum plate is deformed. After pouring a layer of foaming material, the pouring plate 55 is reset, and the aluminum plate moves forward at the same time, and another layer of foaming material is poured. The foaming material is thickened layer by layer to avoid gaps and voids caused by pouring too thickly at one time, so that the pouring of the foaming material can be more complete. With the movement of the conveying mechanism 3 and the telescopic rod 56, the foam board can be poured more evenly. The setting of several nozzles can pour a larger area at one time, thereby improving the pouring efficiency. The latter nozzle fills the gap poured by the previous nozzle, and can further fill the gaps and voids poured in the previous time to obtain a more complete foam board.

[0058] The conveying mechanism 3 includes a plate body 31, which is symmetrically arranged on the top of the base plate 1. The two plates 31 are fixedly connected to the top of the column 4 on one side close to the base plate 1. A conveying roller 32 is provided at the interval between the two plates 31. The two ends of the conveying roller 32 are rotatably connected to the side of the two plates 31 close to each other. There are several conveying rollers 32, and a transmission assembly 33 is arranged at the end of the conveying roller 32. The transmission assembly 33 drives the several conveying rollers 32 to rotate, and the aluminum plate is placed on the top of the conveying roller 32. Then the conveying roller 32 drives the aluminum plate. After pouring and combining with another aluminum plate, the foam board is conveyed.

[0059] The surface of the conveying roller 32 is provided with grooves, and the grooves of the conveying roller 32 are arranged in a threaded shape. The threaded grooves of adjacent conveying rollers 32 are arranged in opposite directions. The grooves on the surface of the conveying roller 32 can increase the friction between the conveying roller 32 and the aluminum plate, thereby preventing the aluminum plate from slipping and ensuring smooth transportation. The threaded grooves can increase the range of the grooves within a limited length, thereby obtaining a better conveying effect. The threaded grooves of adjacent conveying rollers 32 are in opposite directions, which can provide opposite forces to the aluminum plate and offset each other, thereby enhancing the conveying effect while preventing the threaded grooves from causing the aluminum plate to tilt.

[0060] The transmission assembly 33 includes a rotating shaft 331, and there are several rotating shafts 331. The surfaces of the rotating shafts 331 are rotatably connected to the inner side surfaces of the conveying rollers 32. The two ends of the rotating shafts 331 respectively pass through the two plate bodies 31, and the surfaces of the rotating shafts 331 are rotatably connected to the inner side surfaces of the plate bodies 31. Conveyor belts 332 are symmetrically arranged on both sides of the two plate bodies 31. The inner side surfaces of the conveyor belts 332 are transmission-connected to several rotating shafts 331. Driving one rotating shaft 331 to rotate drives the conveyor belt 332 to transmit, thereby driving all the remaining rotating shafts 331 to rotate, thereby driving the conveying rollers 32 to rotate synchronously, ensuring smooth transportation of the foam board.

[0062] See also Figures 1-9 The lifting assembly 7 includes a telescopic column 71, which is fixedly connected to the side of the groove plate 2 close to the bottom plate 1. The side of the telescopic column 71 away from the groove plate 2 is fixedly connected to the sleeve plate 72, and the side of the sleeve plate 72 away from the telescopic column 71 is fixedly connected to the mounting seat 73. The surface of the mounting seat 73 is fixedly connected to the side of the connecting block 8 away from the foaming machine 51. The side of the mounting seat 73 away from the sleeve plate 72 is rotatably connected to the reel 74, and an aluminum plate is wound around the surface of the reel 74. When the telescopic column 71 is started, the telescopic column 71 drives the sleeve plate 72, the mounting seat 73 and the reel 74 to rise and fall, thereby adjusting the distance between the two aluminum plates to achieve the purpose of adjusting the thickness of the foam plate.

[0063] The two plates 31 are fixedly connected to a threaded column 78 on the side away from the base plate 1. The surface of the threaded column 78 is threadedly connected to a sleeve 77. The side of the threaded column 78 away from the plate body 31 is fixedly connected to a limiting column 710. The limiting column 710 is arranged inside the sleeve 77. The surface of the limiting column 710 is slidably connected to the support column 76. The surface of the support column 76 is slidably connected to the inner wall of the sleeve 77. The sleeve 77 is rotated and the sleeve 77 rotates on the surface of the threaded column 78, thereby adjusting the height and limiting the height of the mounting seat 73 to avoid the telescopic distance of the telescopic column 71 being difficult to control, ensuring the adjustment of the thickness of the foam board, and avoiding damage to the foam board caused by excessive telescopic distance.

[0064] The spring 79 is provided inside and outside the sleeve 77. The spring 79 located inside the sleeve 77 is sleeved on the outside of the limit column 710, and the spring 79 is fixedly connected to the side of the support column 76 close to the threaded column 78. The spring 79 located outside the sleeve 77 is sleeved on the outside of the support column 76, and the spring 79 is fixedly connected to the side of the sleeve 77 away from the threaded column 78. The mounting seat 73 contacts the support column 76, and the support column 76 slides inside the sleeve 77, thereby driving the two springs 79 to deform, cushioning the movement of the support column 76, preventing the mounting seat 73 from being excessively impacted, preventing the aluminum plate wound on the reel 74 from being deformed, and avoiding affecting the quality of the foam board. The limit column 710 slides relative to the support column 76. The setting of the limit column 710 can limit the support column 76, prevent the support column 76 from tilting, and ensure the supporting effect.

[0065] A method for using an automatic polyurethane foam board production device comprises the following steps:

[0066] Step 1: Install the aluminum plate. Place one aluminum plate on top of the conveyor roller 32 and wind the other aluminum plate around the reel 74. Then rotate the sleeve 77. The sleeve 77 rotates on the surface of the threaded column 78 to adjust the height, limit the height of the mounting seat 73, and control the thickness of the foam plate. Start the telescopic column 71. The telescopic column 71 drives the sleeve plate 72, the mounting seat 73, and the reel 74 to rise and fall, thereby adjusting the distance between the two aluminum plates and adjusting the thickness of the foam plate.

[0067] Step 2: Aluminum plate buffering. The mounting base 73 contacts the support column 76. The support column 76 slides inside the sleeve 77, thereby causing the two springs 79 to deform and buffer the movement of the support column 76.

[0068] Step 3: Injecting raw materials: inject the black material and the white material into the telescopic tube 52, and then enter the foaming machine 51 to complete the mixing of the black and white materials to form a foamed material. At the same time, the mounting seat 73 moves, driving the connecting block 8 to move, driving the foaming machine 51 to move, and the telescopic tube 52 to expand and contract, completing the production of the foamed material.

[0069] Step 4: Foam board forming. Start the motor 333. The output end of the motor 333 drives a rotating shaft 331 to rotate, which drives the conveyor belt 332 to transmit, thereby driving all the remaining rotating shafts 331 to rotate, thereby driving the conveyor rollers 32 to rotate synchronously. The conveyor rollers 32 drive the aluminum plate. At the same time, the raw materials inside the foaming machine 51 enter the curved pipe 53, then enter the material head 54, and finally flow out from the casting plate 55. The foaming material is poured on the top of the aluminum plate below. The two aluminum plates are combined, and the foaming material expands and solidifies, completing the production of the foam board.

[0070] Step 5: Reciprocating pouring. Start the telescopic rod 56. The connecting plate 57 of the telescopic rod 56 moves, thereby driving the material head 54 to move, the elbow 53 to deform, and at the same time driving the pouring plate 55 to reciprocate. Cooperate with the conveying mechanism 3 to reciprocate pouring on the top of the aluminum plate, and pour the foam board more evenly.
