Description

Technical Field

[0001] The invention relates to the technical field of foamed board production, and in particular to a foamed board production line and method. Background Art

[0002] PVC foam board (referred to as foam board) has the characteristics of light material, convenient production, good heat insulation and sound insulation and low price. It is widely used in decoration, packaging and other fields, and has replaced glass fiber insulation materials, wood, traditional rubber products, etc. in large quantities. The production of existing foam boards usually includes heating, melting, extrusion, shaping, cooling and cutting of plastics. Among them, in the process of extruding into foam boards through extrusion molds, workers need to fix the foam boards extruded by the extrusion molds on the guide plate, and then drive the foam boards to move through the guide plate. However, the foam boards are made by extruding raw materials through extrusion molds after heating and mixing. The temperature of the foam boards just extruded is relatively high. The workers need to pull the foam boards to move through the soft ropes, and then fix the foam boards on the guide plates. However, in this process, since the diameter of the soft ropes is generally thin, the force on the foam boards is relatively concentrated, and the texture of the foam boards just extruded is soft, the foam boards are easily deformed in the process of being driven by the soft ropes, resulting in the deformation and fracture of the force-bearing areas of the foam boards in the process of pulling the foam boards, resulting in the failure of the traction of the foam boards, affecting the normal production of the foam boards.

[0013] Furthermore, a method for using a foam board production line, based on the above-mentioned foam board production line, comprises the following steps:

[0014] S1: The extruder, the extrusion die, the shaping table, the first traction frame, the traction table, the cutting table and the second traction frame are sequentially started through the existing process to produce the foamed board. At this time, the extrusion die fixes the sliding plate. After the extrusion die extrude the foamed board, the motor drives the traction plate to move through the sliding frame. The trapezoidal plate reduces the extrusion force on the sliding plate. The sliding plate drives the extrusion plate to move to clamp the foamed board to complete the initial fixation.

[0015] S2: After the extrusion plate fixes the foam plate, the sliding plate drives the sliding tube to move upward, and the sliding tube drives the elastic plate and the extrusion ring to move the extruded foam plate into the extrusion hole. In this process, the elastic plate is squeezed to deform and expand, increasing the contact area with the foam plate, thereby increasing the fixing force on the foam plate;

[0016] S3: During the process of the extrusion ring extruding the foaming plate, the protrusion of the sliding tube rotates under the action of the curved sliding groove in the rotating ring, driving the sliding tube to rotate, so that the extrusion ring gathers the foaming plate during the rotation process, increasing the contact area between the foaming plate and the extrusion plate;

[0017] S4: When fixing a foam board with a thickness greater than 20 mm, the limit block moves to release the limit on the guide rod, and the guide rod drives the puncture rod to move and insert into the foam board, thereby increasing the fixing force on the foam board and preventing the foam board from falling off;

[0018] S5: After the puncture rod is inserted into the foam board, the two booster plates move to both sides to increase the contact area with the foam board to avoid the foam board from being fractured due to concentrated force;

[0019] S6: After the foaming plate is deformed, the foaming plate drives the detection plate to move, and the detection plate squeezes the U-shaped plate to release the limit of the rotating frame. The guide frame drives the rotating frame to move and rotate through the torsion spring, so that the rotating shafts on the upper and lower sides jointly fix the foaming plate, thereby changing the force position of the foaming plate;

[0020] S7: After the foaming plate is pulled to the designated position, the two sliding plates are pulled away from each other, and the sliding plates drive the parts thereon to separate and reset from the foaming plate, thereby releasing the fixation of the foaming plate. After that, the foaming plate between the two extrusion plates is taken out and placed in the pulling table, and the pulling of the foaming plate is completed.

[0021] The beneficial effects of the present invention are: 1. In the process of driving the foam board to move, the present invention increases the contact area with the foam board by bringing the two extrusion plates close to each other and fixing the foam board, thereby avoiding the situation in which the foam board is deformed and broken due to the concentrated force on the foam board during the process of pulling the foam board to move, thereby affecting the normal production of the foam board.

[0022] 2. The present invention pulls the thick foam board by inserting the puncture rod into the adjacent position of the foam board to increase the force points of the foam board to prevent the foam board from falling off. Then, the booster board is pushed to move by the spring to increase the force area of ​​the foam board to avoid the small force area of ​​the booster board, which will cause the foam board to break and affect the normal traction of the foam board.

[0023] 3. In the process of the extrusion plate pulling the foam plate, when the foam plate is deformed, the rotating shaft is driven to rotate by the rotating frame so that the two rotating shafts fix the foam plate, thereby changing the force position of the foam plate, avoiding that the foam plate is still stressed at the same position after deformation, causing the deformed area of ​​the foam plate to break, and affecting the normal traction of the foam plate.

[0041] When the extruder just produces the foam board, the staff needs to use a soft rope to pull the foam board to move. However, because the soft rope is thin and the foam board is soft, the foam board is subjected to concentrated force and is easy to deform when the soft rope drives the foam board to move. As a result, the force-bearing area of ​​the foam board is easy to deform and break during this process, affecting the normal production of the foam board.

The edge of the extrusion ring 23 is provided with a rounded corner to reduce the shear force on the foaming plate. The extrusion ring 23 is slidably connected with the forming hole of the adjacent extrusion plate 15. The corresponding position of the lower side of the upper extrusion plate 15 is provided with an extrusion hole. The central axis of the forming hole on the lower extrusion plate 15 is coaxial with the central axis of the extrusion hole on the upper extrusion plate 15, which is used to squeeze part of the foaming plate into the corresponding extrusion hole when the extrusion ring 23 moves upward, thereby increasing the contact area with the foaming plate. The extrusion ring 23 is extruded and matched with the extrusion hole on the other extrusion plate 15. After the extrusion ring 23 contacts the extrusion hole on the upper extrusion plate 15, the elastic plate 22 is deformed. The sliding tube 21 is provided with a puncture component for puncturing the foaming plate.

[0044] Combination Figure 7-Figure 10 As shown, the two extrusion plates 15 are fixed with axially distributed rotating rings 31, and the upper extrusion plate 15 is fixed with three rotating rings 31. The seven rotating rings 31 on the two extrusion plates 15 are staggered, and the lower extrusion plate 15 is fixed with four rotating rings 31. The rotating rings 31 are rotatably connected with the adjacent sliding tubes 21. A curved groove is provided in the rotating ring 31, and the sliding tube 21 is provided with a protrusion. The protrusion of the sliding tube 21 is extruded and matched with the curved groove of the adjacent rotating ring 31.

When the positioning plate 44 moves upward relative to the limit block 43, the positioning plate 44 squeezes the slope of the adjacent limit block 43 through the slope on its lower side, so that the limit block 43 moves to the left, and the minimum distance between the rectangular groove and the adjacent limit block 43 in the vertical direction is greater than the height of the curved groove in the rotating ring 31, which is used to move the guide rod 41 again after the extrusion ring 23 stops rotating.

[0046] Combination Figure 8 , Fig. 9 and Fig.11 As shown, the puncture rod 42 is slidably connected with two booster plates 51 symmetrically distributed front and back, and the booster plate 51 is used to increase the contact area with the foaming plate. A tension spring is arranged between the booster plate 51 and the adjacent puncture rod 42, and the tension spring is initially in a stretched state. An inclined surface is arranged on the lower side of the booster plate 51, and the sliding tube 21 is squeezed and matched with the adjacent booster plate 51 to prevent the booster plate 51 from being separated from the adjacent puncture rod 42 without contacting the foaming plate.

The side of the booster plate 51 away from the adjacent puncture rod 42 is provided with two inclined surfaces symmetrically distributed left and right, and the two inclined surfaces are used to facilitate the booster plate 51 to enter the foaming plate, and the connection between the two inclined surfaces is provided with a rounded corner to reduce the damage of the booster plate 51 to the foaming plate.

[0047] When the staff uses the present device to produce foamed boards, the staff starts the foamed board production line through the existing process. At this time, the sliding plate 14 is in contact with the extrusion die 2 and cannot move to the left. After the discharge hole of the extrusion die 2 starts to extrude the foamed board, the staff starts the output shaft of the motor 9 to drive the screw 901 to rotate. The rotation of the screw 901 drives the sliding frame 10 to move to the right. The sliding frame 10 drives the traction plate 11 to move synchronously. The traction plate 11 drives the two L-shaped plates 12 and the trapezoidal plate 16 to move to the right. The extrusion pressure of the inclined surface of the trapezoidal plate 16 on the two sliding plates 14 is reduced. The two sliding plates 14 approach each other under the action of adjacent tension springs, and the sliding plate 14 drives the adjacent extrusion plate 15 and the parts thereon to move synchronously (with the lower side sliding plate 14 and the parts thereon as a reference).

[0048] 1. If a thin foamed board needs to be produced, as the two sliding plates 14 drive the adjacent extrusion plates 15 to approach each other, the extrusion plates 15 drive the parts thereon to move synchronously. When the extrusion plates 15 come into contact with the foamed board, the extrusion plates 15 stop moving, and the sliding plates 14 move upward relative to the adjacent extrusion plates 15 and compress the adjacent springs between the two, so that the extrusion plates 15 gradually increase the extrusion force on the foamed board. In this process, the sliding plates 14 drive the parts thereon to move synchronously and push the four sliding tubes 21 thereon to move through the springs. The sliding tubes 21 drive the adjacent extrusion rings through the elastic plates 22 thereon. 23 moves upward, and the extrusion ring 23 pushes the adjacent foam plate to move upward, so that the foam plate enters the extrusion hole corresponding to the upper extrusion plate 15, thereby increasing the contact area between the foam plate and the extrusion plate 15, strengthening the fixing effect of the foam plate, and avoiding the foam plate and the extrusion plate 15 from sliding relative to each other. When the extrusion ring 23 contacts the other extrusion plate 15 through the foam plate, the extrusion ring 23 stops moving. As the sliding tube 21 continues to move, the elastic plate 22 is deformed by pressure and squeezes the foam plate, so that the foam plate gradually fits the extrusion hole of the extrusion plate 15, until the deformation degree of the elastic plate 22 reaches the maximum, and the sliding tube 21 stops moving.

[0049] In the process of the sliding tube 21 moving upward relative to the adjacent extrusion plate 15, the extrusion plate 15 moves upward adjacent to the rotating ring 31, and the protrusion of the extrusion plate 15 moves along the curved groove of the adjacent rotating ring 31, so that the sliding tube 21 rotates in the process of moving upward, so that the sliding tube 21 drives the adjacent elastic plate 22 and the extrusion ring 23 to rotate synchronously, so that the extrusion ring 23 rolls up the foaming plate near it in the process of moving upward, thereby driving the foaming plate in the adjacent area to move into the adjacent extrusion hole, so that the foaming plate around the two extrusion plates 15 moves between them, increasing the area of ​​the foaming plate between the two extrusion plates 15, thereby strengthening the strength of the connection between the foaming plate and the sliding plate 14.

[0050] In the process that the sliding plate 14 drives the sliding tube 21 to move upward, the sliding plate 14 drives the limit block 43 to move upward, so that the limit block 43 moves upward relative to the adjacent positioning plate 44. Since the thickness of the foaming board is relatively thin at this time, the relative displacement between the sliding plate 14 and the adjacent extrusion plate 15 is relatively small, and the positioning plate 44 still fixes the limit block 43. In this process, when the sliding tube 21 stops moving, the extrusion plate 15 drives the parts thereon to move upward relative to the adjacent sliding tube 21 and compresses the spring between the two. When the sliding plate 14 stops moving, the foaming board is fixed. At this time, the guide plate 13 moves to the left part of the slide groove in the L-shaped plate 12, and the sliding frame 10 drives the guide plate 13 and the parts thereon to move to the right, thereby pulling the foaming board to move to the right. When the sliding frame 10 moves to the right part of the screw 901, the staff turns off the motor 9, and the sliding frame 10 and the parts thereon stop moving.

[0051] After the above-mentioned sliding frame 10 stops moving, the staff pushes the sliding plate 14 to the upper and lower sides respectively, so that the sliding plate 14 moves in the opposite direction to reset and stretch the adjacent tension spring, and the spring between the sliding plate 14 and the adjacent extrusion plate 15 and the sliding tube 21 stretches and resets. As the sliding plate 14 continues to move, when the spring adjacent to the sliding tube 21 is reset, the extrusion force of the sliding tube 21 on the adjacent elastic plate 22 is reduced and it is retracted and reset, until the elastic plate 22 is reset, the elastic plate 22 drives the adjacent molding table 3 to reset and release the fixation of the foaming plate, when the spring adjacent to the extrusion plate 15 is reset, the extrusion plate 15 continues to move and releases the fixation of the foaming plate, the staff takes out the foaming plate, and fixes it after the sliding plate 14 is reset. After the production of the foaming plate is completed, the staff starts the motor 9 to move to the left and reset, until the extrusion plate 15 is reset, the staff turns off the motor 9 and releases the fixation of the sliding plate 14.

[0052] 2. When a thick foam board needs to be produced, the sliding plate 14 repeats the above process to move the extrusion ring 23 and the extrusion plate 15 to fix the foam board. In this process, since the foam board is thicker, the distance between the two extrusion plates 15 is larger, and the extrusion ring 23 moves a small distance and cannot enter the extrusion hole of the upper extrusion plate 15. The relative displacement distance between the extrusion plate 15 and the adjacent sliding plate 14 increases, and the sliding plate 14 drives the adjacent limit block 43 to move into the rectangular groove of the adjacent positioning plate 44, and the positioning plate 44 is released. The limit block 43 is limited, and the limit block 43 moves to the right under the action of the adjacent tension spring, releasing the limit on the adjacent guide rod 41. The guide rod 41 drives the piercing rod 42 thereon to move upward under the action of the adjacent tension spring, and the piercing rod 42 drives the two booster plates 51 thereon to move upward. When the piercing rod 42 contacts the foaming plate, the piercing rod 42 is inserted into the foaming plate, thereby increasing the fixing force on the foaming plate, until the tension spring adjacent to the guide rod 41 is reset (to be in a stretched state), and the guide rod 41 stops moving.

[0053] As the piercing rod 42 moves, when the two booster plates 51 move to the upper side of the extrusion ring 23, the two booster plates 51 move to the front and rear sides respectively under the pull of the adjacent tension springs and squeeze into the foam plate, thereby increasing the force area when the foam plate is pulled to the right, avoiding that the force area of ​​the foam plate is too small, resulting in the foam plate being broken by the force, affecting the traction of the foam plate, until the guide rod 41 and the parts thereon stop moving, and then repeat the above process to drive the foam plate to move to the right. When the traction is completed, the staff pulls the guide rod 41 downward, and the guide rod 41 drives the parts thereon to move downward and stretch Adjacent tension springs, when the inclined surface of the boost plate 51 contacts the adjacent extrusion ring 23, the extrusion ring 23 squeezes the inclined surfaces on the lower sides of the two adjacent boost plates 51, so that the two boost plates 51 are close to each other and stretch the adjacent tension springs to reset. Then the staff repeats the above process to move the sliding plate 14 in the opposite direction to reset and release the fixation of the foaming plate. During this process, the positioning plate 44 squeezes the inclined surface of the adjacent limit block 43, and the limit block 43 moves to the left and stretches the adjacent tension spring until the positioning plate 44 is separated from the inclined surface of the limit block 43, and the limit block 43 completes the reset and limits the adjacent guide rod 41 again.

[0054] Example 2: Based on Example 1, Figure 12-Figure 15 As shown, it also includes two fixing mechanisms symmetrically distributed up and down, the fixing mechanisms are arranged on the adjacent sliding plates 14, the fixing mechanisms are used to squeeze the foaming plate, and the fixing mechanisms include a detection plate 61 (the description of the parts in this paragraph refers to Fig.11), the detection plate 61 is slidably connected to the left part of the upper side of the adjacent extrusion plate 15, a spring is arranged between the detection plate 61 and the adjacent extrusion plate 15, the left part inside the extrusion plate 15 is slidably connected with a guide frame 62, a spring is arranged between the guide frame 62 and the adjacent extrusion plate 15, the spring is initially in a compressed state, the spring is used to push the adjacent guide frame 62 to move to the left, the left side of the guide frame 62 is rotatably connected with two rotating frames 63 symmetrically distributed front and back, a torsion spring is arranged between the rotating frame 63 and the adjacent guide frame 62, the torsion spring is in a force storage state, the torsion spring is used to drive the rotating frame 63 to rotate toward the foaming plate after it is located on the left side of the adjacent detection plate 61, the two rotating frames 63 are both squeezed and matched with the adjacent detection plates 61, and are used for when the rotating frame 63 moves to the right relative to the adjacent detection plate 61 , so that the rotating frame 63 rotates in the opposite direction and resets. A rotating shaft 64 is fixedly connected between the left ends of the two rotating frames 63. The outer side of the rotating shaft 64 is made of rubber material and is used to deform when squeezing the foaming plate to increase the contact area with the foaming plate. The left side of the squeezing plate 15 is slidably connected with two U-shaped plates 65 distributed symmetrically front and back. The upper part of the right side of the U-shaped plate 65 is provided with an inclined surface. The inclined surfaces of the two U-shaped plates 65 are squeezed and matched with the adjacent detection plates 61, and are used to push the U-shaped plates 65 to move backward through the inclined surfaces when the detection plate 61 moves to the left. A spring is provided between the U-shaped plate 65 and the adjacent squeezing plate 15. The spring is always in a compressed state to prevent the U-shaped plate 65 from shaking. The U-shaped plate 65 is limited and matched with the adjacent rotating frame 63. Initially, the U-shaped plate 65 limits the adjacent rotating frame 63 from moving to the left.

[0055] During the process of pulling the foam board, when the pulling force on the foam board is too large, causing deformation of the foam board in some areas, if the foam board is still subjected to a large pulling force, the deformation degree of the foam board increases and it is easy to break, affecting the normal movement of the foam board.

[0056] In the process of the two squeezing plates 15 driving the foaming plates to move to the right, when a part of the foaming plates is deformed, the foaming plates drive the two detection plates 61 to move to the left (taking the detection plate 61 on the lower side as an example), and the detection plate 61 moves to the left to squeeze the inclined surface of the adjacent U-shaped plate 65, so that the two U-shaped plates 65 move away from each other and compress the adjacent springs. At the same time, the U-shaped plate 65 gradually releases the limit on the adjacent rotating frame 63. As the deformation of the foaming plates increases, the distance that the detection plate 61 moves to the left increases, until the inclined surfaces of the two U-shaped plates 65 are separated from the detection plate 61, and the U-shaped plate 65 stops. The adjacent rotating frames 63 are moved and the limit of the adjacent rotating frames 63 is released. The guide frame 62 moves to the left under the push of the adjacent springs. The guide frame 62 drives the two adjacent rotating frames 63 to move to the left. The two rotating frames 63 drive the adjacent rotating shafts 64 to move to the left together until the adjacent springs of the guide frame 62 are reset (the springs are no longer compressed at this time). The guide frame 62 stops moving to the left. At this time, the two rotating frames 63 are located on the left side of the adjacent detection plate 61. The detection plate 61 no longer squeezes the two adjacent rotating frames 63. The rotating frames 63 drive the adjacent rotating shafts 64 to rotate clockwise under the action of the adjacent torsion springs ( Figure 2 Perspective, looking from front to back), during this process, when the rotating shaft 64 contacts the foam board, the rotating shaft 64 squeezes the foam board and deforms, increasing the contact area with the foam board, completing the secondary fixation of the foam board, thereby changing the position where the foam board is subjected to force, reducing the pulling force of the extrusion plate 15 and its parts on the deformed part of the foam board, and preventing the extrusion plate 15 and its parts from continuing to pull the foam board to increase its deformation and break it, resulting in the foam board being unable to move.

[0057] After the adjacent torsion spring of the rotating frame 63 is reset, the rotating frame 63 stops rotating. At this time, the two rotating shafts 64 interlace and squeeze the foaming plate to complete the fixation. Until the foaming plate is pulled, the staff turns off the motor 9. At this time, the staff pushes the rotating frame 63 in the opposite direction to release the fixation of the foaming plate by the rotating shaft 64. The staff repeats the above process to take the foaming plate out from between the two squeezing plates 15 and fix the position of the detection plate 61. Then, the rotating shaft 64 is pushed to the right. The rotating shaft 64 drives the adjacent guide frame 62 to move to the right and reset through the rotating frame 63. The guide frame 62 moves to the right and compresses the adjacent spring until the guide frame 62 is reset. The staff stops pushing the guide frame 62 and releases the fixation of the detection plate 61. The detection plate 61 moves backward under the push of the connecting spring and reduces the squeezing force on the adjacent U-shaped plate 65. The U-shaped plate 65 is reset under the push of the adjacent spring and limits the adjacent rotating frame 63 again. Then, the above process is repeated to fix it after the foaming plate is deformed.

[0058] Embodiment 3: Based on Embodiment 2, Figure 1-Figure 15 As shown, a method for using a foam board production line, based on the above-mentioned foam board production line, comprises the following steps:

[0059] S1: The extruder 1, the extrusion die 2, the shaping table 3, the first traction frame 4, the traction table 5, the cutting table 6 and the second traction frame 7 are sequentially started through the existing process to produce the foamed board. At this time, the extrusion die 2 fixes the sliding plate 14. After the extrusion die 2 extrude the foamed board, the motor 9 drives the traction plate 11 to move through the sliding frame 10, the trapezoidal plate 16 reduces the extrusion force on the sliding plate 14, and the sliding plate 14 drives the extrusion plate 15 to move to clamp the foamed board to complete the initial fixation;

[0060] S2: After the extrusion plate 15 fixes the foaming plate, the sliding plate 14 drives the sliding tube 21 to move upward, and the sliding tube 21 drives the elastic plate 22 and the extrusion ring 23 to move and extrude the foaming plate into the extrusion hole. In this process, the elastic plate 22 is squeezed to deform and expand to increase the contact area with the foaming plate, thereby increasing the fixing force on the foaming plate;

[0061] S3: During the process of squeezing the foaming plate by the squeezing ring 23, the protrusion of the sliding tube 21 rotates under the action of the curved groove in the rotating ring 31, driving the sliding tube 21 to rotate, so that the squeezing ring 23 gathers the foaming plate during the rotation process, increasing the contact area between the foaming plate and the squeezing plate 15;

[0062] S4: When fixing a foam board with a thickness greater than 20 mm, the limit block 43 moves to release the limit on the guide rod 41, and the guide rod 41 drives the puncture rod 42 to move and insert into the foam board, thereby increasing the fixing force on the foam board and preventing the foam board from falling off;

[0063] S5: After the piercing rod 42 is inserted into the foaming plate, the two booster plates 51 move to both sides to increase the contact area with the foaming plate to avoid the foaming plate from being fractured due to concentrated force;

[0064] S6: After the foaming plate is deformed, the foaming plate drives the detection plate 61 to move, and the detection plate 61 squeezes the U-shaped plate 65 to release the limit of the rotating frame 63, and the guide frame 62 drives the rotating frame 63 to move and rotate through the torsion spring, so that the rotating shafts 64 on the upper and lower sides jointly fix the foaming plate, thereby changing the force position of the foaming plate;

[0065] S7: After the foaming board is pulled to the specified position, the two sliding plates 14 are pulled away from each other, and the sliding plates 14 drive the parts thereon to separate and reset from the foaming board, thereby releasing the fixation of the foaming board. Then, the foaming board between the two extrusion plates 15 is taken out and placed in the traction table 5, and the traction of the foaming board is completed.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
