Description

Technical Field

[0001] This utility model relates to the field of PVC foam board shaping technology, and in particular to a PVC foam board cooling and shaping device. Background Technology

[0002] PVC foam board cooling and shaping equipment is a key piece of equipment used in the production process of PVC foam boards. By precisely controlling the cooling temperature and speed, it enables the high-temperature extruded foam boards to cool rapidly and stabilize their dimensions, ensuring a smooth board surface and uniform internal cell structure. At the same time, it eliminates internal stress to improve the mechanical properties and dimensional stability of the product. This equipment usually adopts a multi-stage roller pressing or air-cooled design, equipped with temperature sensors and automatic adjustment systems to achieve efficient and uniform cooling, meeting the production needs of PVC foam boards of different thicknesses and densities.

[0003] Chinese patent CN111016046B discloses a PVC foam board cooling and shaping device. The technical problem addressed by this patent is how to provide a PVC foam board cooling and shaping device that can prevent coolant splashing and achieve rapid cooling. The device includes a base, a support, a protective plate, a cooling box, conveyor rollers, a mounting plate, a rotating shaft, a first connecting rod, a second connecting rod, a sliding frame, and a conveying device. The base has a support and a protective plate on its top two sides. The cooling box is mounted on the support, and it has through holes at both the top and bottom. Conveyor rollers are evenly rotated inside the cooling box. The protective plate has a mounting plate. This invention achieves the effect of preventing coolant splashing and enabling rapid cooling.

[0004] In existing foam board shaping and compression devices, a surface-covered pressing plate is used to press the foam board onto its surface during processing, directly compressing the foam board into shape. However, this forming method makes it prone to overflow at the edges of the foam board, and vertical forming and extrusion cannot solve this technical problem. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PVC foam board cooling and shaping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PVC foam board cooling and shaping device, including a suspension system, and further comprising:

[0008] The sliding shaping component includes a sliding box, the inside of which is provided with a sliding groove, and the inside of the sliding groove is provided with a slot, and the inside of the slot is filled with a foam board.

[0009] A further technical solution involves sliding the slot inside the slide groove.

[0010] A further technical solution involves applying grease to the mating area between the slot and the slide.

[0011] Further technical solutions also include:

[0012] The lifting and shaping assembly includes a cylinder fixedly installed in the middle of the suspension. The output end of the cylinder is provided with a bracket, and the two ends of the bracket are provided with bearing brackets.

[0013] A further technical solution involves installing a rubber pad inside the bearing housing, with the bearing itself filled inside the rubber pad.

[0014] A further technical solution involves installing a crushing pestle inside the bearing, with a motor connected to one side of the crushing pestle.

[0015] A further technical solution involves fixing the motor to one side of the bearing bracket, with the length of the crushing pestle matching that of the foaming board.

[0016] Compared with the prior art, this utility model provides a PVC foam board cooling and shaping device, which has the following beneficial effects:

[0017] This invention features a sliding shaping component that fills the slot with foam board during use. The slot, under the action of the overhead pressing rod, can reciprocate within the groove to counteract edge overflow caused by lateral shearing forces.

[0018] By using a transmission-type lifting and shaping component, the component avoids moving on the surface of the foam board. Instead, it uses a transmission method, employing a rolling mill to press and roll on the surface of the foam board, thereby pulling the slot continuously within the groove. This rolling molding method has a pulling effect on the foam board, ensuring that the foam board at the edges always returns to the center, providing a prerequisite for regular molding.

[0025] Example 1: Refer to Figure 1 - Figure 4 A PVC foam board cooling and shaping device, including a suspension 1, and further comprising:

[0026] The sliding shaping component 2 includes a sliding box 4, and a sliding groove 5 inside the sliding box 4 is the part where the slot 6 slides. The sliding box 4 is provided with a sliding groove 5, and a slot 6 is slidably disposed inside the sliding groove 5. A foam board 7 is filled and installed inside the slot 6, and the foam board 7 fills the inside of the slot 6 to provide a structural basis for subsequent extrusion molding.

[0027] In the aforementioned PVC foam board cooling and shaping equipment, the slot 6 is slidably disposed inside the slide groove 5.

[0028] In the PVC foam board cooling and shaping equipment, the slot 6 and the slide 5 are provided with grease at the joint, which increases the sliding effect of the slot 6 inside the slide 5.

[0029] The aforementioned PVC foam board cooling and shaping equipment further includes:

[0030] The lifting and shaping assembly 3 includes a cylinder 8 fixedly installed in the middle of the suspension 1. The cylinder 8 controls the up and down movement of the bracket 9, thereby achieving the lifting effect of the bottom crushing assembly. The output end of the cylinder 8 is provided with a bracket 9, and the two ends of the bracket 9 are provided with bearing brackets 10, which are the components for mounting the bearings 12.

[0031] In the aforementioned PVC foam board cooling and shaping equipment, a rubber pad 11 is provided inside the bearing frame 10. The function of the rubber pad 11 is to increase the stability of the bearing 12. The bearing 12 is installed inside the rubber pad 11.

[0032] The aforementioned PVC foam board cooling and shaping equipment includes a pressing pestle 13 installed inside the bearing 12, and a motor 14 controlling the rotation of the pressing pestle 13. The motor 14 is connected to one side of the pressing pestle 13.

[0033] The aforementioned PVC foam board cooling and shaping equipment includes a motor 14 fixedly mounted on one side of a bearing bracket 10. The motor 10 controls the rotation of a rolling pestle 13, thereby achieving a rolling and shaping effect on the surface of the foam board 7. The length of the rolling pestle 13 is consistent with that of the foam board 7.

[0034] Working principle:

[0035] In the actual design process, this utility model addresses the following shortcomings in the prior art: "In the processing of existing foam board shaping and compression devices, a surface-covered pressing plate is used to press the foam board onto its surface, directly compressing it into shape. However, this forming method makes it easy for the foam board edges to overflow, and vertical forming and extrusion cannot solve this technical problem." Therefore, a sliding shaping component 2 and a lifting shaping component 3 are specifically proposed.

[0036] Sliding shaping component 2:

[0037] The component comprises two parts: a slot 6 and a groove 7. The slot 6 can slide inside the groove 7 under the action of the top pressing pestle 13, thereby counteracting overflow caused by extrusion. The foaming plate 7 is filled into the interior of the slot 6 to prepare for extrusion molding.

[0038] Lifting and shaping component 3:

[0039] This component controls the vertical movement of the support 9 via a top cylinder 8, thus achieving the lifting effect of the crushing device. A side-mounted motor 14 provides lateral drive for the crushing pestle 13. The crushing pestle 13 presses against the surface of the foaming plate 7, driving the movement of the slot 6, simultaneously achieving crushing and preventing overflow. Furthermore, the crushing pestle 13 can collect any overflowing material during its back-and-forth movement. To ensure stable operation of the crushing pestle 13, the device incorporates a bearing bracket 10, a rubber pad 11, and a bearing 12 structure on the side of the support 9.

[0040] Existing foam board shaping and compression devices use a surface-covered pressing plate to compress the foam board during processing, directly pressurizing it to form the desired shape. However, this forming method easily leads to overflow at the edges of the foam board, and vertical compression cannot solve this problem. This invention utilizes a sliding shaping component that fills the slot with the foam board during use. Under the action of the upper pressing roller, the slot can reciprocate within the groove, offsetting the edge overflow problem caused by lateral shearing forces.

[0041] By using a transmission-type lifting and shaping component, the component avoids moving on the surface of the foam board. Instead, it uses a transmission method, employing a rolling mill to press and roll on the surface of the foam board, thereby pulling the slot continuously within the groove. This rolling molding method has a pulling effect on the foam board, ensuring that the foam board at the edges always returns to the center, providing a prerequisite for regular molding.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
