Description

Technical Field

[0001] This utility model relates to the technical field of PVC foam board production equipment, and in particular to a cooling conveyor roller frame. Background Technology

[0002] Existing PVC foam board production systems typically include an extruder, molding die, cooling conveyor rollers, traction device, cutting machine, and stacking table arranged in sequence. The cooling conveyor rollers support the PVC foam boards shaped by the shaping device and allow them to cool naturally before being pulled to the traction device.

[0003] Chinese patent document CN210617232U discloses a moving structure for a PVC foam board production system. This moving structure includes a cooling conveyor roller frame with its two ends respectively mounted on a shaping device and a support. However, in actual production, it has been found that simply allowing the PVC foam board to cool naturally on the cooling conveyor roller frame cannot guarantee rapid shaping of the PVC foam board. When the PVC foam board is pulled into the traction device, its thickness fluctuates, making it difficult to meet customer requirements for PVC foam board thickness. Utility Model Content

[0004] The purpose of this invention is to provide a cooling conveyor roller frame that solves the problem that existing cooling conveyor roller frames can only achieve natural cooling of PVC foam boards.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows: A cooling conveyor roller frame includes a cooling roller mounting frame and multiple cooling rollers rotatably mounted side-by-side on the mounting frame; it also includes a first air curtain machine, a second air curtain machine, and a dust removal assembly; the first air curtain machine is fixedly mounted above the cooling rollers, and its outlet faces the upper surface of the foam board; the second air curtain machine is fixedly mounted below the cooling rollers, and its outlet faces the lower surface of the foam board; the first air curtain machine is located between the dust removal assembly and the second air curtain machine; the dust removal assembly is located above the cooling rollers and removes dust from the upper surface of the foam board. Optionally, the dust removal assembly includes a support plate and a dust removal towel fixedly wound around the support plate, the support plate being parallel to the cooling roller.

[0006] Optionally, a support plate is provided below both ends of the support plate; the support plate is fixed to the outside of the cooling roller mounting frame, and a limiting rod is vertically provided on the support plate; the limiting rod is vertically inserted through the support plate.

[0007] Optionally, each pallet may have at least two limiting rods.

[0008] Optionally, the surface of the limiting rod is provided with external threads, and a support nut is sleeved on the limiting rod. The support nut is located below the support plate and abuts against the bottom of the support plate.

[0009] Optionally, a limiting nut is fitted onto the limiting rod, and the limiting nut is located above the supporting cross plate.

[0010] Optionally, mounting plates are fixedly mounted above and below the cooling roller mounting frame; the mounting plates are parallel to the cooling roller and are set perpendicular to the horizontal plane; L-shaped connectors are fixed to the back of both the first air curtain machine and the second air curtain machine; the lateral connecting part of the L-shaped connector is detachably mounted on the top or bottom of the mounting plate.

[0011] Optionally, the top and bottom of the mounting plate are both vertically provided with positioning screws; the transverse connecting part of the L-shaped connector is provided with a waist-shaped hole, and a pressing nut is sleeved on the positioning screw, the pressing nut pressing against the transverse connecting part of the L-shaped connector.

[0012] Beneficial effects: This utility model provides a cooling conveyor roller frame. By setting a first air curtain machine and a second air curtain machine above and below the cooling roller respectively, a dual air cooling effect can be formed on the PVC foam board. Compared with the natural cooling of the PVC foam board, it can significantly accelerate the heat dissipation speed of the PVC foam board, prompting the PVC foam board to reach a stable physical state more quickly, achieving rapid shaping, and avoiding significant fluctuations in the thickness of the PVC foam board under the action of the upper and lower traction rollers, thereby meeting the customer's requirements for the thickness of the PVC foam board.

[0013] This invention also removes dust from the surface of the air-cooled PVC foam board by setting a dust removal component above the cooling roller, thus removing the dust generated on the surface of the PVC foam board due to air cooling, further ensuring the production quality of the PVC foam board. When the PVC foam board is used for printing patterns, it can increase the adhesion of the printing layer to the PVC foam board. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] Please see Figures 1 to 4This utility model provides a cooling conveyor roller frame, which is a component of the existing PVC foam board production system and is located between the PVC foam board shaping device 15 and the traction device support 16. The shaping device 15 is located upstream of the cooling conveyor roller frame, and the traction device consists of multiple sets of traction rollers arranged vertically and vertically, and is located downstream of the cooling conveyor roller frame.

[0024] Specifically, the cooling conveyor roller frame includes a cooling roller mounting frame 1, cooling rollers 2, a first air curtain machine 3, a second air curtain machine 4, and a dust removal assembly 6. Multiple cooling rollers 2 are arranged side-by-side and rotate on the cooling roller mounting frame 1. The first air curtain machine 3 is fixedly mounted above the cooling rollers 2, with its outlet facing the upper surface of the foam board. The second air curtain machine 4 is fixedly mounted below the cooling rollers 2, with its outlet facing the lower surface of the foam board. The outlets of both the first and second air curtain machines 3 and 4 are arranged parallel to the length of the cooling rollers 2. Therefore, the first and second air curtain machines 3 and 4 can simultaneously blow air from both the upper and lower sides of the PVC foam board 5, creating a dual air-cooling effect. Compared to natural cooling, this significantly accelerates the heat dissipation of the PVC foam board 5, allowing it to reach a stable physical state more quickly, achieving rapid shaping and preventing significant fluctuations in the thickness of the PVC foam board 5 under the action of the upper and lower traction rollers, thus meeting customer requirements for the thickness of the PVC foam board 5.

[0025] Furthermore, the first air curtain machine 3 is located between the dust removal component 6 and the second air curtain machine 4; the dust removal component 6 is located above the cooling roller 2, and the dust removal component 6 removes dust from the upper surface of the air-cooled foam board, so that the dust generated on the upper surface of the PVC foam board 5 due to air cooling can be removed, further ensuring the production quality of the PVC foam board 5. When the PVC foam board 5 is used for printing patterns, it can increase the adhesion of the printing layer to the PVC foam board 5. like Figure 1 and Figure 2 As shown, in an optional embodiment, the dust removal assembly 6 includes a support plate 601 and a dust removal towel 602 fixedly wound around the support plate 601. The support plate 601 is parallel to the cooling roller 2. In this embodiment, the dust removal towel 602 can be fixed with adhesive tape after being wound around the support plate 601. The support plate 601, which is parallel to the cooling roller 2, can provide a stable mounting base for the dust removal towel 602. When the dust removal towel 602 is fixedly wound around the support plate 601, it can ensure that the dust removal towel 602 can thoroughly and continuously wipe and remove dust from the upper surface of the PVC foam board 5, effectively removing dust generated by air cooling and ensuring the production quality of the PVC foam board.

[0026] Moreover, compared to other dust removal tools, the dust removal towel 602 has a certain degree of flexibility. When it comes into contact with the PVC foam board 5 for dust removal, it can ensure the dust removal effect while avoiding scratches or damage to the surface of the PVC foam board 5. Furthermore, the dust removal towel 602 is very convenient to replace or clean in the future, making it easy to maintain a long-term stable dust removal function.

[0027] like Figure 1 and Figure 2 As shown, in an optional embodiment, a support plate 7 is provided below both ends of the support plate 601; the support plate 7 can be fixed to the outside of the cooling roller mounting frame 1 by welding, and a limiting rod 8 is vertically provided on the support plate 7; the limiting rod 8 is vertically inserted through the support plate 601. In this embodiment, by setting the support plate 7 below the support plate 601 and using the limiting rod 8 on the support plate 7 to limit the support plate 601, the support plate 601 is prevented from shifting in the horizontal direction, ensuring that the support plate 601 always remains parallel to the cooling roller 2, thereby ensuring that the dust removal towel 602 wrapped around the support plate 601 can contact the upper surface of the PVC foam board 5 evenly and stably to achieve effective dust removal.

[0028] like Figure 1 and Figure 2 As shown, in an optional embodiment, each support plate 7 is provided with at least two limiting rods 8, and each limiting rod 8 on each support plate 7 is on the same straight line, thereby forming a stable limit on the supporting horizontal plate 601. At the same time, multiple limiting rods 8 can also distribute the force on the supporting horizontal plate 601 and improve the support stability.

[0029] like Figure 1 and Figure 2 As shown, in an optional embodiment, the surface of the limiting rod 8 is provided with external threads, and a support nut 9 is sleeved on the limiting rod 8. The support nut 9 is located below the supporting horizontal plate 601 and abuts against the bottom of the supporting horizontal plate 601. In this embodiment, the position of the support nut 9 can be flexibly adjusted along the limiting rod 8 in the vertical direction. Therefore, by rotating the support nut 9, the height of the supporting horizontal plate 601 can be adjusted to accommodate PVC foam boards 5 of different thicknesses. This ensures that the dust removal towel 602 wrapped around the supporting horizontal plate 601 always maintains a suitable contact pressure with the upper surface of the PVC foam board 5, which can both ensure the dust removal effect and avoid damage to the PVC foam board 5.

[0030] like Figure 1 and Figure 2As shown, in an optional embodiment, a limiting nut 14 is sleeved on the limiting rod 8. The limiting nut 14 is located above the supporting horizontal plate 601 and can further limit the position of the supporting horizontal plate 601 from above. Together with the supporting nut 9 located at the bottom of the supporting horizontal plate 601, it can clamp the supporting horizontal plate 601, thereby preventing the supporting horizontal plate 601 from moving due to equipment vibration. This ensures that the supporting horizontal plate 601 is always at the preset working height, and thus ensures that the dust removal towel 602 wrapped around the supporting horizontal plate 601 can stably and evenly contact the upper surface of the PVC foam board to achieve continuous and effective dust removal.

[0031] like Figure 1 , Figure 3 as well as Figure 4 As shown, in an optional embodiment, mounting plates 10 are fixedly mounted above and below the cooling roller mounting frame 1; the mounting plates 10 are parallel to the cooling roller 2 and are arranged perpendicular to the horizontal plane; multiple L-shaped connectors 11 can be welded and fixed to the back of the first air curtain machine 3 and the second air curtain machine 4; the lateral connecting part of the L-shaped connector 11 can be detachably installed on the top or bottom of the mounting plate 10, which facilitates the disassembly and assembly of the air curtain machine and the maintenance and repair of the air curtain machine.

[0032] like Figure 1 and Figure 3 As shown, in an optional embodiment, both the top and bottom of the mounting plate 10 are vertically fixed with positioning screws 12; the transverse connecting portion of the L-shaped connector 11 is provided with a waist-shaped hole 111, which is arranged in a direction parallel to the length direction of the mounting plate 10; a pressing nut 13 is sleeved on the positioning screw 12, and the pressing nut 13 presses against the transverse connecting portion of the L-shaped connector 11.

[0033] In the above embodiments, the top and bottom of the mounting plate 10 can be provided with insertion holes (not shown in the figure) for threaded connection with the positioning screw 12. The positioning screw 12 can provide a positioning base for the L-shaped connector 11, ensuring that the installation positions of the first air curtain machine 3 and the second air curtain machine 4 will not deviate significantly when installed through the L-shaped connector 11. The design of the waist-shaped hole 111 allows the positioning screw 12 to be inserted into the waist-shaped hole 111 and the position of the L-shaped connector 11 to be finely adjusted. This allows the lateral position of the first air curtain machine 3 and the second air curtain machine 4 to be flexibly adjusted according to the actual cooling requirements of the PVC foam board 5, so that the air outlets of the first air curtain machine 3 and the second air curtain machine 4 can be more accurately aligned with the upper and lower surfaces of the foam board, thus optimizing the air cooling effect. When the pressing nut 13 presses against the transverse connecting part of the L-shaped connector 11, it can firmly fix the L-shaped connector 11 to the mounting plate 10, preventing the first air curtain machine 3 and the second air curtain machine 4 from shifting their positions due to vibration during operation, thus ensuring the stability of air cooling.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
