Description

Technical Field

[0001] This utility model relates to the field of PVC flooring processing technology, and in particular to a rolling device for PVC flooring. Background Technology

[0002] As a common floor decoration material, PVC flooring undergoes a crucial process in its production: roll forming. This process not only determines the final thickness and flatness of the flooring but is also typically used to press specific decorative patterns onto the flooring surface.

[0003] However, existing PVC flooring rolling equipment has general limitations in its structural design. Usually, the distance between the upper and lower rollers of this type of equipment is fixed or very cumbersome to adjust. This means that a single machine can often only process flooring products of a specific thickness. When market demand changes or different thickness series of products need to be produced, manufacturers must invest in purchasing multiple machines of different specifications or carry out time-consuming and labor-intensive modifications to existing equipment. This undoubtedly increases production costs and seriously restricts the flexibility and adaptability of the production line.

[0004] Furthermore, as a component that comes into direct contact with the floor, the pressure roller will wear down over time, especially the patterned upper pressure roller, which requires more frequent replacement. In existing technology, the pressure roller is usually fixed to the frame by complex bearing housings and fasteners. The replacement process requires disassembling multiple related components such as the transmission system and bearing housings. The operation is complicated, requires highly skilled maintenance personnel, and the whole process is time-consuming. This inefficient maintenance method leads to excessive downtime of the equipment, which directly affects the continuity and capacity of the entire production line.

[0005] Therefore, this utility model proposes a rolling device for PVC flooring to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of PVC flooring rolling equipment, such as the fixed spacing of the pressure rollers leading to a narrow range of applications, and the complicated, time-consuming and labor-intensive process of replacing worn pressure rollers, which seriously affects production efficiency, this utility model aims to provide a PVC flooring rolling equipment with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a rolling device for PVC flooring, including: a lower fixed plate, an upper fixed plate, and a lower pressure roller and an upper pressure roller respectively rotatably connected to the lower fixed plate and the upper fixed plate, with protruding columns at both ends of the upper pressure roller and the lower pressure roller; as well as a support column, a hydraulic column and a quick release mechanism.

[0008] The support column is vertically fixed to one side of the lower fixed plate, and the hydraulic column is connected between the support column and the upper fixed plate to drive the upper fixed plate to move up and down in the vertical direction to adjust the distance between the upper and lower pressure rollers.

[0009] Furthermore, the quick-release mechanism is used for the rapid assembly and disassembly of the upper and lower pressure rollers. The quick-release mechanism includes a fixing block, a limiting hole, a limiting pin, a connector, and a motor. The inner side of the fixing block is provided with a slot for accommodating the protrusion and is detachably installed at the ends of the upper and lower fixing plates. The limiting hole is opened at the ends of the upper and lower fixing plates, and the limiting pin passes through the fixing block and is inserted into the limiting hole to lock the fixing block. The connector is detachably coaxially connected to the end of the protrusion away from the fixing block. The motor is fixedly connected to the connector through its output shaft to drive the connector to rotate, thereby driving the pressure rollers to work.

[0010] Preferably, the PVC flooring rolling equipment also includes a support block, which is fixedly connected to the bottom of the lower fixed plate. The support block has a large contact area and is used to provide stable support for the entire equipment, preventing the equipment from shaking or shifting during the rolling process and ensuring processing accuracy.

[0011] Preferably, the PVC floor rolling equipment also includes a placement box, which is fixedly installed on the lower fixing plate or support block and encloses the motor and connector inside. The structure not only effectively protects the transmission components from dust but also prevents accidental contact by operators, thus improving operational safety.

[0012] Preferably, the PVC flooring rolling equipment also includes a heater, which is built into the upper and lower rollers or arranged around their outer perimeter, to preheat the rollers before rolling, ensuring that the flooring material has good plasticity when pressing patterns, and improving the clarity and adhesion of the patterns.

[0013] Preferably, based on the above-mentioned heater configuration, the outer peripheral surface of the upper pressure roller is also provided with a pattern. After the electric heater heats the upper pressure roller, the pattern with a certain temperature is deeply pressed onto the floor surface through rolling, realizing the completion of rolling forming and embossing decoration in one process, simplifying the production process.

[0014] Preferably, as a specific implementation method, the hydraulic column is a telescopic hydraulic cylinder. By precisely controlling the extension and retraction stroke of its piston rod, it is possible to achieve micron-level precise control over the lifting and lowering position of the upper fixed plate, thereby flexibly adapting to the processing needs of flooring of different thicknesses.

[0015] Preferably, by driving the upper fixed plate to move by a hydraulic column, a rolling angle can be formed between the upper and lower pressure rollers, where the distance at the entrance is greater than the distance at the exit. The floor blank enters from a wider entrance and is gradually rolled to the preset thickness. This gradual pressing method helps to expel air bubbles inside the material, making the finished product denser.

[0016] Preferably, as a reliable connection method, the limit pin and the limit hole are tightly fitted. During installation, the interference fit generates a strong clamping force, ensuring that the fixing block can still be firmly locked under long-term vibration conditions of the equipment, without loosening or falling off, thus ensuring production safety.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a support column, a hydraulic column, and an upper fixed plate that can move up and down, solves the defects of the existing rolling equipment where the pressure roller spacing is fixed and cannot adapt to the processing needs of different thicknesses of flooring. It achieves the beneficial effect of being able to flexibly adjust the equipment according to the thickness of the screen plate and expand the scope of application.

[0018] 2. This utility model solves the problems of cumbersome and time-consuming replacement process after pressure roller wear, which affects production efficiency in the prior art by setting a quick-release mechanism consisting of a fixed block, a limiting pin, a protruding post and a connector. It achieves the beneficial effects of quick disassembly and installation of pressure rollers, shortening equipment downtime for maintenance and improving efficiency.

[0019] 3. This utility model, by setting patterns on the surface of the upper pressure roller and heating the pressure roller with a heater, can complete the pressing of surface patterns while rolling, simplifying the production process and improving the aesthetics and added value of the product.

[0022] Please refer to Figures 1 to 2This utility model provides a rolling device for PVC flooring, which aims to solve the problems of low production efficiency caused by the inability of existing rolling devices to adapt to flooring of different thicknesses and the complicated process of changing the pressure rollers.

[0023] like Figure 1 and Figure 2 As shown, a PVC flooring rolling device includes a lower fixed assembly and an upper movable assembly disposed above the lower fixed assembly. The lower fixed assembly includes a support block 1 for supporting the entire device and a lower fixed plate 4 fixedly connected to the top of the support block 1. A lower pressure roller 7 is rotatably connected to the lower fixed plate 4. The upper movable assembly includes an upper fixed plate 5, and an upper pressure roller 6 is rotatably connected to the upper fixed plate 5. A support column 3 is vertically fixed to one side of the lower fixed plate 4, and a hydraulic column 8 is connected between the support column 3 and the upper fixed plate 5. The hydraulic column 8 is a telescopic structure, which drives the upper fixed plate 5 to move up and down in the vertical direction to adjust the processing distance between the upper pressure roller 6 and the lower pressure roller 7.

[0024] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the PVC floor rolling equipment further includes a quick-release mechanism 2, and the quick-release mechanism 2 forms a specific structural cooperation and connection relationship with the aforementioned lower fixed plate 4, upper fixed plate 5, lower pressure roller 7 and upper pressure roller 6.

[0025] Please refer to Figure 1 and Figure 2 The structure will be explained in detail below: The quick-release mechanism 2 includes a fixing block 201, a limiting pin 202, a connector 205, and a motor 206. Both ends of the upper pressure roller 6 and the lower pressure roller 7 are integrally formed with protrusions 204. The inner side of the fixing block 201 is provided with a slot for accommodating the protrusions 204, and the fixing block 201 is detachably installed on the ends of the upper fixing plate 5 and the lower fixing plate 4 away from the motor 206. The ends of the upper fixing plate 5 and the lower fixing plate 4 are respectively provided with limiting holes 203 for the insertion of the limiting pin 202. During assembly, the limiting pin 202 passes through the fixing block 201 and inserts into the limiting hole 203, locking the fixing block 201. The limiting pin 202 and the limiting hole 203 are tightly fitted to ensure that the fixing block 201 will not loosen during equipment vibration. Simultaneously, the other end protrusions 204 of the upper pressure roller 6 and the lower pressure roller 7 are detachably coaxially connected to the connector. The output shaft of the motor 206 is fixedly connected to the connector 205 to drive the connector 205 to rotate, thereby driving the pressure roller to rotate. The motor 206 and the connector 205 are housed inside the placement box 207 fixedly mounted on the lower fixed plate 4. This quick-release structure, in which the fixing block 201 locked by the limit pin 202 and the plug-in connector 205 cooperate with each other, ensures that when the pressure roller needs to be replaced, the operator only needs to pull out the limit pin 202 and remove the fixing block 201 to pull out the protrusion 204 of the pressure roller from the connector 205, which greatly improves the replacement efficiency. The equipment also includes a heater 10, which is built into the upper pressure roller 6 and the lower pressure roller 7 to heat the pressure roller. The outer circumferential surface of the upper pressure roller 6 is provided with a pattern 9. After the heater 10 heats the upper pressure roller 6, the pattern 9 is pressed onto the floor surface by rolling.

[0026] In a preferred embodiment, to achieve precise adjustment of the pressure roller spacing, the hydraulic column 8 is specifically a telescopic hydraulic cylinder. The telescopic hydraulic cylinder includes a cylinder barrel and a piston rod that can reciprocate within the cylinder barrel. The extended end of the piston rod is hinged to the upper fixed plate 5, and the end of the cylinder barrel is hinged to the support column 3. By controlling the flow rate and pressure of the hydraulic oil entering the hydraulic cylinder, precise control of the piston rod's extension and retraction stroke is achieved, thereby completing the fine adjustment and locking of the vertical position of the upper fixed plate 5. By controlling the extension and retraction of the hydraulic column 8, the upper fixed plate 5 is inclined relative to the lower fixed plate 4. Specifically, a rolling angle is formed between the upper pressure roller 6 and the lower pressure roller 7, where the distance at the entrance is greater than the distance at the exit. The floor is fed in from the side with the larger distance and is gradually compacted as it passes through the pressure rollers, which is beneficial to improving the pressing quality.

[0027] As another preferred embodiment, in order to enhance the overall structural stability of the equipment, the bottom of the lower fixed plate 4 is fixedly connected to a support block 1 by bolts or welding. The support block 1 has a large bottom area, which is used to evenly distribute the weight of the entire equipment to the ground and prevent the equipment from shaking or shifting during operation.

[0028] As another preferred embodiment, in order to protect the transmission components, the device also includes a placement box 207. The placement box 207 is fixedly installed on the side of the lower fixing plate 4 near the motor 206 by bolts, and completely encloses the motor 206 and the connector 205 inside it. The placement box 207 can effectively prevent dust, debris and other external debris from entering the transmission mechanism and avoid accidental contact by operators, thereby improving the safety and reliability of the device operation.

[0029] As a further optimization of the quick-release mechanism 2, in order to ensure the absolute reliability of the locking connection, the outer diameter of the limit pin 202 and the inner diameter of the limit hole 203 are designed to be tightly fitted. During installation, external force is required to press the limit pin 202 into the limit hole 203. The interference generated by the mating surface is used to achieve self-locking, effectively resisting the vibration and impact generated during equipment operation and preventing the limit pin 202 from accidentally loosening.

[0030] Working principle: First, when the equipment is in use, the hydraulic column 8 supported by the support column 3 is started, causing the hydraulic column 8 to extend and retract, allowing the upper fixed plate 5 to move up and down. After the upper fixed plate 5 is adjusted to a position between it and the lower fixed plate 4 that can accommodate the floor, and the lower fixed plate 4 and the upper fixed plate 5 are tilted so that the inlet to outlet is from large to small, then the upper pressure roller 6 and the lower pressure roller 7 roll the floor. At the same time, the heater 10 heats the upper pressure roller 6 and the lower pressure roller 7 so that the pattern 9 presses the desired pattern onto the floor. During processing, the support block 1 supports the lower fixed plate 4, which achieves the effect of adjusting the equipment according to the thickness of the floor, thus improving the applicability. First, when it is necessary to replace the upper pressure roller 6 and the lower pressure roller 7, the quick-release mechanism 2 is required. When the upper pressure roller 6 and the lower pressure roller 7 are worn and need to be replaced, the fixing block 201 on the lower fixing plate 4 and the upper fixing plate 5 is removed. The fixing block 201 is fixed in the limiting hole 203 opened in the lower fixing plate 4 and the upper fixing plate 5 by the limiting pin 202. Hold the upper pressure roller 6 and the lower pressure roller 7 and pull the protrusion 204 out of the connector 205 for replacement. The motor 206 can drive the connector 205 to rotate, so that the equipment can run. At the same time, the placement box 207 fixes and protects the motor 206, which achieves the effect of quick replacement of parts and improves the efficiency of use.
