Description

Technical Field

[0001] The invention belongs to the field related to foam board processing technology, and more specifically relates to an anti-oxidation PVC foam board and processing equipment thereof. Background Art

[0002] PVC foam board is a lightweight, high-strength board. It is made by mixing PVC resin, foaming agent, stabilizer and other auxiliary additives and extruding them into shape through a specific production process. At the same time, during the extrusion process, the foaming agent is heated and expanded to form bubbles, thus giving the board good foaming properties.

[0003] Patent document CN111267329A discloses a PVC free-foaming board production device, comprising a machine body, a calendering mechanism fixedly connected to the middle of the upper surface of the machine body, a feed cavity fixedly connected to the left side of the upper surface of the machine body, a feed hopper fixedly connected to the top of the feed cavity, and a servo motor fixedly connected to the top of the machine body and to the left of the feed hopper. The PVC free-foaming board production device has eight rotating rods evenly fixedly connected to opposite sides of the upper and lower rotating rollers. When the foaming material moves, it moves in the same direction as the corresponding contacting rotating rods, preventing the rotating rods from sticking to the foaming material, thereby improving the smoothness of the foamed board produced by the PVC free-foaming board production device. At the same time, the sliding connection replaces the original sliding friction contact method.

[0004] The above equipment has certain shortcomings in the processing operation of PVC foam boards. After the PVC foam boards are formed, the burrs on both sides need to be trimmed to keep both sides of the PVC foam boards smooth. However, the above equipment cannot flexibly trim PVC foam boards of different widths, and cannot perform synchronous discharge adjustment for PVC foam boards of different widths, which reduces its trimming effect on PVC foam boards of different widths; secondly, after the PVC foam boards are processed and formed, the PVC foam boards need to be stacked and transferred. Traditional equipment uses a manipulator in conjunction with a suction cup structure to complete the transfer and stacking operations of the PVC foam boards. The operation steps are cumbersome and the efficiency is low. It is easy to cause the stacked PVC foam boards to be misaligned, which increases the difficulty of transfer; secondly, in order to increase its antioxidant and wear resistance, the PVC foam boards will be double-sided laminated. PVC foam boards of different specifications have different thicknesses. Traditional equipment cannot meet the lamination operations of PVC foam boards of different thicknesses and has a single functionality. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-oxidation PVC foam board and processing equipment thereof, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. After the PVC foam board is formed, the burrs on both sides need to be trimmed to keep both sides of the PVC foam board smooth. However, the above equipment cannot flexibly trim PVC foam boards of different widths, and cannot perform synchronous discharge adjustment for PVC foam boards of different widths, which reduces its trimming effect on PVC foam boards of different widths;

[0008] 2. After the PVC foam board is processed and formed, it needs to be stacked and transferred. Traditional equipment uses a robot with a suction cup structure to complete the transfer and stacking of the PVC foam board. The operation steps are cumbersome and inefficient.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0017] As a further technical solution of the present invention, the material organizer includes a telescopic rod and a docking socket. The telescopic rod is movably sleeved in the middle position of the inner side of the docking socket. The outer surface of the telescopic rod is located on one side of the docking socket and is equipped with a movable slider. The movable slider is movably installed in the slide groove of the material receiving frame. When it is necessary to perform material organizing operations on PVC foam boards of different sizes, the material organizer is moved by using the movable slider. The position of the material organizer on both sides of the material receiving frame can be adjusted so that the material organizer can meet the use of PVC foam boards of different sizes.

[0018] As a further technical solution of the present invention, a limit plate is movably installed on the outer surface of the telescopic rod, and the telescopic rod and the limit plate are connected by threads. A control cabinet is fixedly installed on the front end of the fixed base, and the material organizer adopts a manual structure setting. The user pushes the telescopic rod to make the telescopic rod drive the second push plate to move, and the limit adjustment of both sides of the PVC foam board is completed by two groups of second push plates.

Both ends of the upper reel and the lower reel are connected and fixed by a feed rack, and a conveyor belt is provided on the upper part of the other end of the fixed base. The upper reel and the lower reel respectively release the upper film body and the lower film body, so that the upper film body and the lower film body are respectively adhered to the two sides of the PVC foam board, thereby improving the wear resistance of the PVC foam board.

[0020] As a further technical solution of the present invention, elastic sleeves are provided at both ends of the upper reel, and the elastic sleeves and the feed frame are movably connected by a lifting slider. The lifting slider can be used to drive the elastic sleeves to move up and down, thereby adjusting the use height of the upper reel. Secondly, the elasticity between the lifting slider and the elastic sleeve is utilized to make the upper reel have an elastic rolling structure.

[0021] Beneficial effects of the present invention:

By arranging a material guide and a knife disc, when the material guide and the knife disc are used in the processing equipment for the antioxidant PVC foam board, it is provided with an adjustable PVC foam board rolling and trimming structure, and the corresponding discharge adjustment can be performed according to the width of the PVC foam board, thereby improving its application range;

[0023] During operation, the cutting knife of the cutting box and two sets of knife discs can be used to cut the foam board to a fixed length and roll and trim the burrs on both sides. During the movement of the foam board, the two sets of knife discs are in rolling contact with the two sides of the foam board. Secondly, the cutter is driven back and forth by the crankshaft, so that the cutter completes the cutting operation of the foam board by shearing. In order to meet the side trimming operation of PVC foam boards of different widths, a bidirectional screw rod is used in conjunction with a threaded slider so that the two sets of knife discs can be adjusted in position synchronously. The user drives the bidirectional screw rod to rotate through the motor, and drives the threaded slider to move through the bidirectional thread structure on the surface of the bidirectional screw rod, so that the threaded slider drives the cutter disc, thereby adjusting the distance between the two sets of knife discs. Secondly, the setting of the elastic top rod makes the two sets of knife discs have an elastic rolling cutting structure, which improves the rolling cutting of the two sets of knife discs on both sides of the PVC foam board. After the two sets of cutter discs complete the rolling cutting operation on both sides of the PVC foam board, the edge materials generated will be discharged into the edge material box through the material guide for collection. In order to meet the position adjustment of the two sets of cutters, the material guide belt can be adjusted accordingly according to the position changes of the two sets of cutters by setting the material guide belt. First, the material guide belt is installed in the edge material box in a roll shape, and one end of the material guide belt is fixed on the slot of the rotating card seat. When the position of the rotating card seat changes, the rotating card seat pulls one end of the material guide belt to move, so that the length of the material guide belt changes. After locking and fixing the material guide belt, the edge material can be guided to the material guide for discharge through the material guide belt, so that the material guide belt moves with the cutter, thereby improving its use effect on PVC foam boards of different widths.

[0024] 2. By setting up a material receiving frame, when the processing equipment for anti-oxidation PVC foam board is used, it has an auxiliary material-handling structure, which replaces the transmission suction cup manipulator to complete the stacking and handling operation of the PVC foam board, making it convenient for the PVC foam board to be transferred;

[0025] During use, after the cutter completes the slitting operation of the PVC foam board, the PVC foam board automatically falls onto the feeding plate cart inside the receiving frame through the conveyor belt. The two sets of trimmers installed on the receiving frame are used to align and adjust the two sides of the PVC foam board so that the two sides of the stacked PVC foam boards are aligned. When it is necessary to perform trimming operations on PVC foam boards of different sizes, the trimmers can be moved by moving the slider to adjust the position of the trimmers on both sides of the receiving frame so that the trimmers can meet the use of PVC foam boards of different sizes. The trimmers adopt a manual structure setting, and the user By pushing the telescopic rod, the telescopic rod drives the second push plate to move, and the two groups of second push plates are used to complete the limit adjustment of both sides of the PVC foam board. Secondly, the position of the limit plate can be adjusted according to the width of the PVC foam board, so that when the telescopic rod moves, the limit fixation of the telescopic rod is completed by the limit plate, and the electric push rod is used to drive the first push plate to move so that the first push plate contacts one end of the PVC foam board. The first push plate pushes several layers of PVC foam boards to move, so that the other end of the PVC foam board abuts against the feeding trolley, thereby completing the alignment operation of the two ends of the several layers of PVC foam boards.

[0026] 3. By setting a lifting slider and an elastic sliding sleeve, when the processing equipment for anti-oxidation PVC foam board is used, it has an adjustable elastic rolling structure to meet the laminating operation of PVC foam boards of different thicknesses and improve its laminating effect;

[0027] During operation, the upper drum and the lower drum release the upper film body and the lower film body respectively, so that the upper film body and the lower film body are respectively adhered to the two sides of the PVC foam board, thereby improving the oxidation resistance and wear resistance of the PVC foam board. The lifting slider can be used to drive the elastic sleeve to move up and down, thereby adjusting the use height of the upper drum. When the lifting slider moves to the corresponding height, it is locked and fixed to meet the lamination needs of PVC foam boards of different thicknesses. Secondly, the elasticity between the lifting slider and the elastic sleeve is used to make the upper drum have an elastic rolling structure, thereby improving the lamination effect of the PVC foam board.

[0037] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0038] like Figure 1As shown, an anti-oxidation PVC foam board and processing equipment thereof include a lower plate body 33 and an upper plate body 34. The lower plate body 33 is fixedly mounted on the outer surface of the upper end of the upper plate body 34. The lower plate body 33 and the upper plate body 34 are fixed by gluing. The lower plate body 33 and the upper plate body 34 are formed into strip grooves 31 by a rolling structure during the extrusion process. The strip grooves 31 are distributed in a strip shape on the surfaces of the lower plate body 33 and the upper plate body 34. The strip grooves 31 of the lower plate body 33 and the strip grooves 31 of the lower plate body 33 are staggered and butted. The outer surface of the lower plate body 33 is covered with a lower film body 32, and the outer surface of the upper plate body 34 is covered with an upper film body 35. Through the setting of the strip groove 31, a hollow structure can be formed inside the PVC foam board. At the same time, when the strip groove 31 is formed, the structural strength of the lower plate body 33 and the upper plate body 34 will be improved, so that the foam board occupied by the strip groove 31 is integrated into the entire plate body. The setting of the lower film body 32 and the upper film body 35 completes the double-sided lamination operation of the PVC foam board, thereby improving its anti-oxidation performance.

[0039] like Figure 2 As shown, a processing equipment for antioxidant PVC foam board includes a fixed base 1 and a cutting box 10. The cutting box 10 is fixedly installed on the upper outer surface of the fixed base 1. The outer surfaces of both sides of the cutting box 10 are fixedly installed with material guides 2. The upper end of the cutting box 10 is movably installed with a bidirectional screw rod 11, and the lower part of the bidirectional screw rod 11 is movably installed with two sets of knife discs 18. One end of the cutting box 10 is movably installed with a cutter 9. The cutting knife 9 of the cutting box 10 and the two sets of knife discs 18 can be used to cut the foam board to a fixed length and roll and trim the burrs on both sides. During the movement of the foam board, the two sets of knife discs 18 are in rolling contact with both sides of the foam board. Secondly, the cutter 9 is driven back and forth by a crankshaft, so that the cutter 9 completes the cutting operation of the foam board by shearing.

[0040] To solve the problem of trimming PVC foam boards of different widths, such as Figure 3 As shown, the outer surface of the bidirectional screw rod 11 is movably mounted with two groups of threaded sliders 15 for use with the cutter disc 18, and the lower end of the threaded slider 15 is elastically mounted with a rotating base 17, and the threaded slider 15 and the rotating base 17 are elastically connected by an elastic push rod 16, and the cutter disc 18 is movably mounted on the inner side of the rotating base 17. In order to meet the side trimming operation of PVC foam boards of different widths, the bidirectional screw rod 11 is coordinated with the threaded slider 15 so that the two groups of cutter discs 18 can be adjusted in position synchronously. The user drives the bidirectional screw rod 11 to rotate through the motor, and drives the threaded slider 15 to move through the bidirectional thread structure on the surface of the bidirectional screw rod 11, so that the threaded slider 15 drives the cutter disc 18, thereby adjusting the distance between the two groups of cutter discs 18. Secondly, the setting of the elastic push rod 16 is used to make the two groups of cutter discs 18 have an elastic rolling cutting structure, thereby improving the rolling cutting effect of the two groups of cutter discs 18 on both sides of the PVC foam board.

[0041] In order to solve the problem of discharging PVC foam boards of different widths, Figure 4 As shown, a guide belt 19 is movably installed inside the material guide 2, and a positioning wheel 20 is provided on one side of the material guide 2 for cooperating with the material guide belt 19. A slot is provided at the end of the rotary card seat 17 for fixing the material guide belt 19. After the two sets of knife discs 18 complete the rolling cutting operation on both sides of the PVC foam board, the edge material generated will be discharged into the edge material box 3 for collection through the material guide 2. In order to meet the position adjustment of the two sets of cutters 9, the material guide belt 19 can be adjusted accordingly according to the position change of the two sets of cutters 9. First, the material guide belt 19 is installed in the edge material box 3 in a roll shape, and one end of the material guide belt 19 is fixed on the slot of the rotary card seat 17. When the position of the rotary card seat 17 changes, the rotary card seat 17 pulls one end of the material guide belt 19 to move, so that the length of the material guide belt 19 changes. After the material guide belt 19 is locked and fixed, the edge material can be guided to the material guide 2 for discharge through the material guide belt 19, so that the material guide belt 19 moves with the cutter 9.

[0042] In order to solve the problem of loading and storing PVC foam boards of different widths, Figure 5 As shown, side material boxes 3 are fixedly installed on both sides of the fixed base 1, a material receiving frame 6 is fixedly installed on the outer surface of one end of the fixed base 1, and material organizers 5 are movably installed on both sides of the material receiving frame 6, and a feeding trolley 7 is spliced and installed at one end of the material receiving frame 6. When the cutter 9 completes the slitting operation of the PVC foam board, the PVC foam board automatically falls onto the feeding trolley 7 inside the material receiving frame 6 through the conveyor belt 8, and the two sets of material organizers 5 installed on the material receiving frame 6 are used to align and adjust the two sides of the PVC foam board, so that the two sides of the stacked PVC foam boards are aligned.

[0043] like Figure 5 As shown, an electric push rod 21 is installed at the other end of the material receiving frame 6, and a first push plate 22 is installed at the end of the electric push rod 21. A second push plate 23 is installed at the end of the material sorter 5. When the material receiving frame 6 performs the material sorting operation, the electric push rod 21 is first used to drive the first push plate 22 to move, so that the first push plate 22 contacts one end of the PVC foam board, and the first push plate 22 pushes several layers of PVC foam boards to move, so that the other end of the PVC foam board is in contact with the feeding trolley 7, thereby completing the alignment operation of the two ends of several layers of PVC foam boards.

[0044] In order to solve the problem of loading and storing PVC foam boards of different widths, Figure 6As shown, the material organizer 5 includes a telescopic rod 24 and a docking seat 25. The telescopic rod 24 is movably sleeved in the middle position of the inner side of the docking seat 25. The outer surface of the telescopic rod 24 is located on one side of the docking seat 25 and is equipped with a movable slider 26. The movable slider 26 is movably installed in the slide groove of the material receiving frame 6. When it is necessary to perform material organizing operations on PVC foam boards of different sizes, the material organizer 5 is moved by using the movable slider 26. The position of the material organizer 5 on both sides of the material receiving frame 6 can be adjusted so that the material organizer 5 can meet the use of PVC foam boards of different sizes.

[0045] A limit plate 27 is movably installed on the outer surface of the telescopic rod 24. The telescopic rod 24 and the limit plate 27 are connected by threads. The control cabinet 4 is fixedly installed on the front end of the fixed base 1. The material organizer 5 adopts a manual structure setting. The user pushes the telescopic rod 24 to make the telescopic rod 24 drive the second push plate 23 to move. The limit adjustment of both sides of the PVC foam board is completed through the two groups of second push plates 23. Secondly, the position of the limit plate 27 can be adjusted according to the width of the PVC foam board, so that when the telescopic rod 24 moves, the limit fixation of the telescopic rod 24 is completed through the limit plate 27.

[0046] In order to solve the problem of laminating PVC foam boards of different thicknesses, such as Figure 7 As shown, an upper reel 13 and a lower reel 14 are provided on the inner side of one end of the fixed base 1, and the upper reel 13 is movably mounted on the upper part of the lower reel 14. A rolling rod 12 is provided on one side of the upper reel 13, and both ends of the upper reel 13 and the lower reel 14 are connected and fixed by a feed rack 30. A conveyor belt 8 is provided on the upper part of the other end of the fixed base 1, and the upper reel 13 and the lower reel 14 respectively release the upper membrane body 35 and the lower membrane body 32, so that the upper membrane body 35 and the lower membrane body 32 are respectively adhered to the two sides of the PVC foam board, thereby improving the wear resistance of the PVC foam board.

[0047] Elastic sleeves 29 are provided at both ends of the upper reel 13. The elastic sleeve 29 and the feed frame 30 are movably connected by a lifting slider 28. The lifting slider 28 can drive the elastic sleeve 29 to move up and down, thereby adjusting the use height of the upper reel 13. Secondly, the elasticity between the lifting slider 28 and the elastic sleeve 29 is utilized to make the upper reel 13 have an elastic rolling structure.

[0048] During use, after the PVC foam board is formed, the burrs on both sides need to be trimmed to keep both sides of the PVC foam board smooth. However, the above equipment cannot flexibly trim PVC foam boards of different widths, and cannot perform synchronous discharge adjustment for PVC foam boards of different widths, which reduces its trimming effect on PVC foam boards of different widths.

[0049] To this end, by providing the material guide 2 and the cutter disc 18, when the antioxidant PVC foam board processing equipment is used, it has an adjustable PVC foam board rolling and trimming structure, and can also adjust the corresponding discharge according to the width of the PVC foam board, thereby improving its scope of application;

[0050] During operation, the cutting knife 9 of the cutting box 10 and the two sets of knife discs 18 can be used to cut the foam board to a fixed length and roll and trim the burrs on both sides respectively. During the movement of the foam board, the two sets of knife discs 18 are in rolling contact with the two sides of the foam board. Secondly, the cutting knife 9 is driven back and forth by the crankshaft, so that the cutting knife 9 completes the cutting operation of the foam board by shearing. In order to meet the side trimming operation of PVC foam boards of different widths, the bidirectional screw rod 11 is used to cooperate with the threaded slider 15 so that the two sets of knife discs 18 can be synchronously adjusted in position. The user drives the bidirectional screw rod 11 to rotate through the motor, and drives the threaded slider 15 to move through the bidirectional thread structure on the surface of the bidirectional screw rod 11, so that the threaded slider 15 drives the cutter disc 18, thereby adjusting the distance between the two sets of knife discs 18. Secondly, the setting of the elastic push rod 16 is used to make the two sets of knife discs 18 have an elastic rolling cutting structure, which improves the rolling cutting of the two sets of knife discs 18 on both sides of the PVC foam board. The cutting blades 9 are moved along the cutting edge 19 to move the cutting edge 19 to the cutting edge 19, thereby improving the cutting effect.

[0051] Secondly, after the PVC foam board is processed and formed, it needs to be stacked and transferred. Traditional equipment uses a robot with a suction cup structure to complete the transfer and stacking operation of the PVC foam board. The operation steps are cumbersome and inefficient, and it is easy to cause the stacked PVC foam boards to be misaligned, which increases the difficulty of transfer.

[0052] To this end, by setting the material receiving frame 6, when the antioxidant PVC foam board processing equipment is used, it has an auxiliary material-forming structure, which replaces the transmission suction cup manipulator to complete the stacking and material-forming operation of the PVC foam board, making it convenient for the PVC foam board to be transferred;

[0053] During use, after the cutter 9 completes the slitting operation of the PVC foam board, the PVC foam board automatically falls onto the feeding plate trolley 7 inside the receiving frame 6 through the conveyor belt 8, and the two sets of trimmers 5 installed on the receiving frame 6 are used to align and adjust the two sides of the PVC foam board so that the two sides of the stacked PVC foam boards are aligned. When it is necessary to perform trimming operations on PVC foam boards of different sizes, the trimmer 5 is moved by moving the slider 26, and the position of the trimmer 5 on both sides of the receiving frame 6 can be adjusted so that the trimmer 5 can meet the use of PVC foam boards of different sizes. The trimmer 5 adopts a manual structure setting, and the user pushes the telescopic Rod 24, so that the telescopic rod 24 drives the second push plate 23 to move, and the limit adjustment of both sides of the PVC foam board is completed through the two groups of second push plates 23. Secondly, the position of the limit plate 27 can be adjusted according to the width of the PVC foam board, so that when the telescopic rod 24 moves, the limit fixation of the telescopic rod 24 is completed by the limit plate 27. The electric push rod 21 is used to drive the first push plate 22 to move, so that the first push plate 22 contacts one end of the PVC foam board, and the first push plate 22 pushes several layers of PVC foam boards to move, so that the other end of the PVC foam board abuts against the feeding plate car 7, thereby completing the alignment operation of the two ends of the several layers of PVC foam boards;

[0054] To increase its oxidation resistance and wear resistance, PVC foam boards are double-sided laminated. However, PVC foam boards of different specifications have different thicknesses. Traditional equipment cannot meet the lamination requirements of PVC foam boards of different thicknesses and has a single function.

[0055] To this end, by providing a lifting slider 28 and an elastic sliding sleeve 29, when the processing equipment for the anti-oxidation PVC foam board is used, it has an adjustable elastic rolling structure to meet the laminating operation of PVC foam boards of different thicknesses and improve the laminating effect;

[0056] During operation, the upper drum 13 and the lower drum 14 release the upper film body 35 and the lower film body 32 respectively, so that the upper film body 35 and the lower film body 32 are respectively adhered to the two sides of the PVC foam board, thereby improving the oxidation resistance and wear resistance of the PVC foam board. The lifting slider 28 can drive the elastic sleeve 29 to move up and down, thereby adjusting the use height of the upper drum 13. When the lifting slider 28 moves to the corresponding height, it is locked and fixed to meet the coating use of PVC foam boards of different thicknesses. Secondly, the elasticity between the lifting slider 28 and the elastic sleeve 29 is utilized to make the upper drum 13 have an elastic rolling structure, thereby improving the coating effect of the PVC foam board.
