Description

Technical Field

[0001] This utility model belongs to the field of foam board technology, specifically, it relates to a shaping table for PVC foam board production. Background Technology

[0002] PVC foam board, also known as Chevron board or Andy board, is made of polyvinyl chloride. It is chemically stable, resistant to acids, alkalis, and corrosion, and is moisture-proof, mildew-proof, heat-insulating, sound-absorbing, flame-retardant, self-extinguishing, smooth, insect-proof, lightweight, and non-absorbent. PVC free-foamed board has a moderate surface hardness and is widely used in advertising display boards, mounting boards, screen printing, engraving, etc. In the production process of PVC foam board, various raw materials are generally mixed first, then extruded through an extruder, shaped through a mold, and then extruded and shaped by the upper and lower shaping frames on the shaping table.

[0003] Chinese patent CN216182675U discloses a shaping table for PVC foam board production, including a base. Support plates are installed on the upper left and right sides of the base. A top plate is installed on the top of both support plates. An electric push rod is installed on the upper part of the top plate. A horizontal plate is installed at the bottom of the electric push rod. A groove is formed at the bottom of the horizontal plate, and multiple threaded rods are rotatably installed in the groove. A common upper shaping frame is threaded onto the lower ends of two threaded rods. Slider blocks are installed on both the left and right sides of the upper shaping frame. A distance sensor is installed at the bottom of the left slider. A lower shaping frame is installed in the upper middle part of the base, and a cavity is formed inside the lower shaping frame. This prior art shapes the foam board using two shaping frames. Because the volume of the raw material fluctuates before shaping, excess material is squeezed to the sides during shaping, causing irregular edges and affecting the overall size. Only the thickness of the foam board can be adjusted, not the width, requiring secondary processing and thus affecting overall production efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a shaping table for the production of PVC foamed boards, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A shaping table for producing PVC foamed boards includes: a workbench, characterized in that a support frame is provided on the top of the workbench near the right side, a hydraulic cylinder is provided at the center of the top of the support frame, a hydraulic rod is provided at the bottom of the hydraulic cylinder, an upper shaping frame is provided at the bottom of the hydraulic rod, a lower shaping frame is provided at the bottom of the inner side of the support frame, a cutting frame is provided on the left side of the support frame, an installation seat is installed inside the cutting frame, and a cutter is provided at the bottom of the installation seat.

[0008] Optionally, an adjusting screw is installed longitudinally through the inside of the cutting frame.

[0009] Optionally, a heat-conducting seat is provided inside the lower shaping frame, a water tank is provided at the bottom of the workbench, water pipes are provided through the support frame on both the front and back sides of the lower shaping frame, and a water pump is provided at the top of the water tank.

[0010] Optionally, a conveyor roller is provided on the left side of the cutting frame, a pulley is provided on the front side of the conveyor roller, a belt is sleeved on the surface of the pulley, and a motor is provided on the front side of the pulley.

[0011] Optionally, a cooling platform is provided between the conveying rollers, a heat-conducting seat is provided inside the cooling platform, and water pipes are provided on both the front and back sides of the cooling platform.

[0012] Optionally, the cooling table and the conveyor roller are at the same height, and the lower shaping frame is higher than the cooling table and the conveyor roller.

[0013] Optionally, the surface material of the conveyor roller is heat-resistant rubber with high friction.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. The PVC foam board production shaping table shapes the foam board raw material by closing the upper and lower shaping frames inside the support frame. The adjustable mounting base can adjust the position of the cutter and cut the foam board according to the actual width requirements of the foam board, ensuring edge shaping and accurate overall dimensions. No secondary cutting processing is required, thus improving the overall processing efficiency.

[0016] 2. The PVC foam board production shaping table uses rotating conveyor rollers to assist in pushing the material and quickly produce finished foam boards. The heat-conducting seat on the lower shaping frame and cooling table quickly transfers heat from the foam board. The internal water flow absorbs heat to quickly cool the foam board, resulting in a faster shaping speed.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown in the figure, this embodiment provides a shaping table for PVC foam board production, including: a workbench 1.

[0029] like Figure 1 , 2As shown, in this embodiment, a support frame 2 is provided near the right side of the top of the workbench 1. A hydraulic cylinder 5 is provided at the center of the top of the support frame 2, a hydraulic rod 4 is provided at the bottom of the hydraulic cylinder 5, an upper shaping frame 3 is provided at the bottom of the hydraulic rod 4, a lower shaping frame 6 is provided at the bottom of the inner side of the support frame 2, a cutting frame 8 is provided on the left side of the support frame 2, a mounting base 9 is installed inside the cutting frame 8, and a cutter 10 is provided at the bottom of the mounting base 9; wherein, the upper shaping frame 3 is lowered by controlling the hydraulic rod 4 through the hydraulic cylinder 5, and the foamed board raw material is put into it from the right side of the support frame 2, and the upper shaping frame 3 is lowered and the hydraulic rod 4 is lowered through the hydraulic cylinder 5. The lower shaping frame 6, fixed at the bottom, closes and compresses to complete the initial shaping operation. The actual thickness of the foam board is controlled by the hydraulic cylinder 5, which controls the descent height of the upper shaping frame 3. After shaping, the foam board is pushed through the cutting frame 8. The cutter 10, mounted on the bottom of the mounting base 9 on the cutting frame 8, is suspended on both sides with its blade aligned with the direction of the foam board. It cuts the foam board on both sides, making the originally irregular sides smoother, thus eliminating the trouble of subsequent cutting and trimming. The cutter 10 is fixed to the mounting base 9 with screws and can be replaced at any time to achieve the best cutting effect.

[0030] like Figure 4 As shown, in this embodiment, an adjusting screw 11 is longitudinally installed inside the cutting frame 8. The mounting base 9 has a threaded hole, through which the adjusting screw 11 passes. By rotating the adjusting screw 11, the mounting base 9 moves within the cutting frame 8. The mounting base 9 will not flip because it is embedded in the cutting frame 8. In addition, the adjusting screw 11 is a double-ended screw with opposite thread directions at both ends, so that the mounting base 9 moves in opposite directions when it is rotated, thereby adjusting the distance between the two mounting bases 9 and thus adjusting the position of the cutter 10. Since the width of the foam board after cutting is the distance between the two cutters 10, the width of the foam board after cutting can be adjusted by rotating the adjusting screw 11 to adjust the cutter 10.

[0031] like Figure 3 As shown, the lower shaping frame 6 in this embodiment is equipped with a heat-conducting seat 7 inside, and a water tank 14 is provided at the bottom of the workbench 1. Water pipes 13 are provided through the support frame 2 on both the front and back sides of the lower shaping frame 6, and a water pump 15 is provided at the top of the water tank 14. The lower shaping frame 6 is hollow inside and is connected to the water tank 14 through the water pipes 13 on both sides. The water pump 15 pressurizes the water and injects water into the lower shaping frame 6 through the water pipes 14 to form a water circulation. During shaping, multiple sets of heat-conducting seats 7 connected to the top are attached to the foam board. The heat-conducting seats 7 are made of a material with high thermal conductivity and quickly absorb the heat of the foam board, thereby cooling the foam board. The heat is then carried away by the water flow and returned to the water tank 14.

[0032] like Figure 1As shown, in this embodiment, a conveyor roller 16 is provided on the left side of the cutting frame 8, a pulley 18 is provided on the front of the conveyor roller 16, a belt 19 is sleeved on the surface of the pulley 18, and a motor 17 is provided on the front of the pulley 18. When the foam board extends from the cutting frame 8, it is pushed to the top of the conveyor roller 16 from behind. The motor 17 drives the conveyor roller 16 to rotate, and the friction of the conveyor roller 16 pushes the foam board to the left for conveying. Multiple sets of conveyor rollers 16 can rotate simultaneously to cooperate in conveying the foam board. The pulleys 18 on each set of conveyor rollers 16 are connected by belts 19. After the motor 17 drives one conveyor roller 16 to rotate, it drives all the conveyor rollers 16 to rotate simultaneously through the belts 19 to assist in the conveying of the foam board.

[0033] like Figure 3 As shown, a cooling platform 12 is provided between the conveying rollers 16 in this embodiment. A heat-conducting seat 7 is provided inside the cooling platform 12, and water pipes 13 are provided on both the front and back sides of the cooling platform 12. During the conveying process, the foamed board comes into contact with the cooling platform 12, and the cooling platform 12 further cools it down. Its working principle is the same as that of the lower shaping frame 6. The two sides are connected to the water tank 14 through the water pipes 13, and the internal heat-conducting seat 7 absorbs heat to complete the cooling.

[0034] like Figure 2 As shown, in this embodiment, the cooling platform 12 and the conveying roller 16 are at the same height, while the lower shaping frame 6 is higher than the cooling platform 12 and the conveying roller 16. After the foam board is pushed out, the front end will sag due to the large cavity area of ​​the cutting frame 8. By reducing the height of the conveying roller 16 relative to the lower shaping frame 6, the receiving of the conveying roller 16 is ensured. The cooling platform 12, which is at the same height as the conveying roller 16, ensures that the bottom of the foam board is in contact with the cooling platform 12, increasing the contact area to ensure the heat absorption effect.

[0035] like Figure 1 As shown, the surface material of the conveyor roller 16 in this embodiment is heat-resistant rubber with high friction. The conveyor roller 16 is pushed to the left by rotating the friction foam plate. The greater the friction, the better the pushing effect. Since the temperature of the foam plate is high, a corresponding heat-resistant material is needed to extend its service life in order to prevent it from melting.

[0036] Working principle: The foam board material is pushed into the support frame 2. The hydraulic cylinder 5 controls the hydraulic rod 4 to lower the upper shaping frame 3. The foam board is initially shaped by the extrusion of the upper shaping frame 3 and the lower shaping frame 6. The heat-conducting seat 7 in the lower shaping frame 6 absorbs the heat of the foam board and cools it down by absorbing the heat through water flow, thus quickly completing the shaping effect. Then the upper shaping frame 3 is raised, and the adjusting screw 11 is rotated to adjust the distance between the cutters 10 under the two mounting seats 9. The foam board is pushed through the cutter 10 to complete the cutting of both sides of the foam board, thereby determining the molding size. Finally, the motor 17 drives the conveying roller 16 to rotate and carry the foam board to the cooling table 12 for further cooling.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
