AI Technical Summary
In existing plastic flooring embossing devices, the distance between the embossing roller and the abutment roller is fixed, which results in the pattern depth being formed in one step. This makes it impossible to press patterns with greater depth, and shallower patterns are not obvious enough.
Multiple auxiliary rollers with varying spacing from the embossing rollers are used for multiple embossing processes. The PVC flooring is embossed three times by the cooperation of multiple auxiliary rollers and embossing rollers, gradually reducing the gap to deepen the pattern. Heating and cooling devices are used to improve the clarity of the pattern.
It achieves gradual deepening of patterns, making the pattern imprints more obvious and profound, improving the embossing effect, and supports multiple molding processes, enhancing the versatility and efficiency of the equipment.

Description
Technical Field
[0001] This utility model relates to the technical field of flooring processing, and in particular to a plastic flooring embossing device. Background Technology
[0002] PVC flooring often features textured surfaces, created by embossing equipment. Chinese utility model patent CN219055325U discloses an embossing device for PVC flooring. This device includes a frame; a heating device with its heating surface facing the outer surface of the PVC flooring to heat the surface layer, connected to the frame; and an embossing roller for embossing the heated PVC flooring, rotatably connected to the frame with its rotation axis aligned with and perpendicular to the transmission direction of the PVC flooring. The heating device and embossing roller are arranged sequentially along the transmission direction of the PVC flooring, resulting in clearly visible and permanently retained patterns on the surface.
[0003] However, the above-mentioned embossing device is equipped with an embossing roller and a matching abutment roller. The distance between the embossing roller and the abutment roller is fixed, which means that the depth of the pattern is formed in one step. Since the interaction time between the embossing roller and the abutment roller is relatively short, it is not possible to press out a deeper pattern in one step, and the shallower pattern imprint is not obvious enough. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a plastic flooring embossing equipment that improves the embossing quality by setting multiple auxiliary rollers with different spacing from the embossing roller to achieve multiple embossing processes.
[0005] This utility model discloses a plastic flooring embossing device, comprising a frame and an embossing roller, the embossing roller being rotatably mounted on the frame via a rotating shaft one; it also includes a sub-frame one, a sub-abutment roller one, a sub-abutment roller two, a sub-frame two, and a sub-abutment roller three. The sub-frame one is mounted at the front of the frame, the sub-abutment roller one is rotatably mounted on the sub-frame one via a rotating shaft two, and an embossing gap one is provided between the sub-abutment roller one and the embossing roller; the sub-abutment roller two is rotatably mounted on the frame via a rotating shaft three, and an embossing gap two is provided between the sub-abutment roller two and the embossing roller; the sub-frame two is mounted at the rear of the frame, the sub-abutment roller three is rotatably mounted on the sub-frame two via a rotating shaft four, and an embossing gap three is provided between the sub-abutment roller three and the embossing roller; the embossing gap one... The embossing gaps 2 and 3 gradually decrease. During operation, the end of the PVC flooring passes through the gap 1 between the auxiliary roller 1 and the embossing roller, the gap 2 between the auxiliary roller 2 and the embossing roller, and the gap 3 between the auxiliary roller 3 and the embossing roller in sequence. This allows the embossing roller to work with the auxiliary rollers 1, 2, and 3 to emboss the PVC flooring three times. As the embossing gaps 1, 2, and 3 gradually decrease, the pattern on the PVC flooring deepens through the three embossing processes, making the pattern more obvious and profound, thus improving the embossing effect. Multiple auxiliary rollers 1, 2, and 3 can also be set as needed to achieve multiple embossing processes.
[0006] Preferably, it also includes multiple rotary joints, electric slip rings, and multiple heaters. Cooling water pipes are installed inside the auxiliary roller 1, auxiliary roller 2, and auxiliary frame 2. The rotating shafts 2, 3, and 4 of the auxiliary roller 1 are hollow tubular and connected to the internal cooling water pipes. Rotary joints are installed at the ends of the rotating shafts 2, 3, and 4 of the auxiliary roller 1 and auxiliary roller 2. Electric slip rings are installed on the rotating shaft 1 of the embossing roller. Multiple heaters are evenly installed around the inner circumference of the embossing roller. The multiple heaters are connected to the output of the electric slip rings. The system is electrically connected; multiple rotary joints are connected to an external cooling water system, allowing cold water to be fed into the cooling water pipes inside the auxiliary rollers 1, 2, and 3 through the rotary joints. This allows the auxiliary rollers 1, 2, and 3 to cool the back of the plastic flooring. Simultaneously, the input of the electric slip ring is connected to an external power source, and the output of the electric slip ring supplies power to multiple heaters, which heat the embossing rollers. This heats the plastic flooring during embossing, making it easier for patterns to form on the plastic flooring.
[0007] Preferably, the device further includes multiple inductive switches, sensor one, and sensor two. The multiple inductive switches are respectively installed on multiple heaters and electrically connected to multiple heaters. Sensor one and sensor two are installed on the frame. Sensor one is located at the rear of the frame and above the auxiliary roller three. Sensor two is located at the front of the frame and above the auxiliary roller one. Sensor one and sensor two are matched and aligned with the multiple inductive switches. When the embossing roller rotates, it drives the multiple heaters to rotate. When the heater rotates to the rear of the frame and disengages from the auxiliary roller three, and the inductive switch of the heater is aligned with sensor one, the inductive switch activates to de-energize the heater. When the heater rotates to the front of the frame and enters before the auxiliary roller one, and the inductive switch of the heater is aligned with sensor two, the inductive switch activates to energize the heater, so that the multiple heaters are energized and de-energized in an orderly manner, reducing energy waste.
[0008] Preferably, it also includes a gap adjustment assembly, which is installed on the frame and the second sub-frame. The gap adjustment assembly is used to adjust the size of the gap between the second sub-roller and the embossing roller and the gap between the third sub-roller and the embossing roller. By setting the gap adjustment assembly, it is convenient to adjust the size of the gaps, improves versatility.
[0009] Preferably, the gap adjustment assembly includes a slide table, a lead screw, and a threaded sleeve. The slide table is slidably mounted on the frame or the auxiliary frame. The rotating shaft of the auxiliary roller 2 or the rotating shaft of the auxiliary roller 3 is rotatably connected to the slide table. One end of the lead screw is rotatably connected to the slide table. The threaded sleeve is mounted on the frame, and the lead screw and the threaded sleeve are rotatably screwed together. When the lead screw is rotated, the screw and the threaded sleeve engage to push the slide table to move, so that the slide table 1 drives the auxiliary roller 2 or the auxiliary roller 3 to move, thereby adjusting the size of the gap 2 between the auxiliary roller 2 and the embossing roller or the gap 3 between the auxiliary roller 3 and the embossing roller. The structure is simple and the operation is convenient.
[0010] Preferably, the gap adjustment assembly includes a slide table two, a worm gear, a worm wheel, and a helical rack. The slide table two is slidably mounted on the frame or sub-frame two. The rotating shaft three or four of the sub-abutment roller two is rotatably connected to the slide table two. The worm gear is rotatably mounted on the slide table two via a bracket. The worm wheel is rotatably mounted on the slide table two, and the worm gear meshes with the worm wheel. The helical rack is mounted on the frame or sub-frame two, and the worm wheel meshes with the helical rack. Rotating the worm gear drives the worm wheel to rotate, and the worm wheel meshes with the helical rack to drive the slide table two to move along the frame or sub-frame two, thereby adjusting the size of the gap two between the sub-abutment roller two and the embossing roller, or the gap three between the sub-abutment roller three and the embossing roller. The structure is simple and the operation is convenient.
[0011] Preferably, it also includes a crossbeam, a cooler, and a fan. The crossbeam is installed at the rear of the frame, the cooler is installed on the crossbeam, and the fan is installed on the cooler. The cooler is located above and behind the third auxiliary roller. The plastic flooring formed by the embossing roller and the third auxiliary roller passes under the cooler, with the patterned surface facing the cooler. The fan blows cold air through the cooler onto the plastic flooring, causing the patterned surface of the plastic flooring to cool and solidify quickly.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the end of the plastic flooring passes through the gap one between the auxiliary roller one and the embossing roller, the gap two between the auxiliary roller two and the embossing roller, and the gap three between the auxiliary roller three and the embossing roller in sequence. This allows the embossing roller to cooperate with the auxiliary roller one, auxiliary roller two, and auxiliary roller three to perform three embossing operations on the plastic flooring. As the embossing gap one, embossing gap two, and embossing gap three gradually decrease, the pattern of the plastic flooring is gradually deepened after three embossing operations, making the pattern imprint more obvious and profound, thus improving the embossing effect. Multiple auxiliary rollers one, two, and three can also be set as needed to achieve multiple embossing molding. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a plastic flooring embossing device includes a frame 1 and an embossing roller 2, which is rotatably mounted on the frame 1 via a rotating shaft 1. It also includes a secondary frame 3, a secondary abutment roller 4, a secondary abutment roller 5, a secondary frame 6, and a secondary abutment roller 7. The secondary frame 3 is mounted at the front of the frame 1. The secondary abutment roller 4 is rotatably mounted on the secondary frame 3 via a rotating shaft 2, with an embossing gap 1 between the secondary abutment roller 4 and the embossing roller 2. The secondary abutment roller 5 is rotatably mounted on the frame 1 via a rotating shaft 3, with an embossing gap 2 between the secondary abutment roller 5 and the embossing roller 2. The secondary frame 6 is mounted at the rear of the frame 1. The auxiliary abutment roller 3 7 is rotatably mounted on the auxiliary frame 2 6 via the rotating shaft 4. An embossing gap 3 is provided between the auxiliary abutment roller 3 7 and the embossing roller 2. The embossing gap 1, embossing gap 2 and embossing gap 3 gradually decrease. The pitch adjustment assembly includes a slide table 1 13, a lead screw 14 and a threaded sleeve 15. The slide table 1 13 is slidably mounted on the frame 1 or the auxiliary frame 2 6. The rotating shaft 3 of the auxiliary abutment roller 2 5 or the rotating shaft 4 of the auxiliary abutment roller 3 7 is rotatably connected to the slide table 1 13. One end of the lead screw 14 is rotatably connected to the slide table 1 13. The threaded sleeve 15 is mounted on the frame 1, and the lead screw 14 and the threaded sleeve 15 are rotatably screwed together.
[0022] Rotating the lead screw 14 as needed causes the lead screw 14 to engage with the threaded sleeve 15, which in turn moves the slide table 13. This causes the slide table 13 to move the secondary abutment rollers 2 and 3, thereby adjusting the size of the gaps between the secondary abutment roller 2 and embossing roller 2 and between the secondary abutment roller 3 and embossing roller 2. During operation, the end of the plastic flooring passes through the gaps between the secondary abutment roller 1 and embossing roller 2, the secondary abutment roller 2 and embossing roller 2, and the secondary abutment roller 3 and embossing roller 2 in sequence. This allows the embossing roller 2 to work with the secondary abutment rollers 1, 2, and 3 to perform three embossing operations on the plastic flooring. As the embossing gaps 1, 2, and 3 gradually decrease, the pattern on the plastic flooring becomes progressively deeper after three embossing operations, making the pattern more obvious and profound, thus improving the embossing effect. Multiple secondary abutment rollers 1, 2, and 3 can also be set as needed to achieve multiple embossing processes. Example 2
[0023] like Figures 1 to 4As shown, based on Embodiment 1, it further includes multiple rotary joints 8, electric slip rings 9, and multiple heaters 10. Cooling water pipes are installed inside the secondary roller 4, secondary roller 5, and secondary frame 6. The rotating shafts of secondary roller 4, secondary roller 5, and secondary roller 7 are hollow tubular and connected to the internal cooling water pipes. Rotary joints 8 are installed at the ends of the rotating shafts of secondary roller 4, secondary roller 5, and secondary roller 7. The electric slip rings 9 are installed on the rotating shaft of the embossing roller 2. Multiple heaters 10 are evenly installed on the inner circumference of the embossing roller 2, and the multiple heaters 10 are electrically connected to the output of the electric slip rings 9. It also includes multiple inductive switches 11, sensor 12, and sensor 23. Multiple inductive switches 11 are respectively installed on multiple heaters 10, and the multiple inductive switches 11 are electrically connected to the multiple heaters 10. Sensor 12 and Sensor 23 are installed on the frame 1. Sensor 12 is located at the rear of the frame 1 and above the auxiliary roller 3 7. Sensor 23 is located at the front of the frame 1 and above the auxiliary roller 4. Sensor 12 and Sensor 23 are matched and aligned with the multiple inductive switches 11. The system also includes a crossbeam 20, a cooler 21, and a fan 22. The crossbeam 20 is installed at the rear of the frame 1. The cooler 21 is installed on the crossbeam 20. The fan 22 is installed on the cooler 21. The cooler 21 is located above and behind the auxiliary roller 3 7.
[0024] Multiple rotary joints 8 are connected to an external cooling water system, allowing cold water to be fed into the cooling water pipes inside the auxiliary abutment rollers 4, 5, and 7 respectively. This allows the auxiliary abutment rollers 4, 5, and 7 to cool the back of the plastic flooring. Simultaneously, the input of the electric slip ring 9 is connected to an external power source, and the output of the electric slip ring 9 supplies power to multiple heaters 10. These heaters heat the embossing roller 2, making it easier for patterns to form on the plastic flooring during embossing. The rotation of the embossing roller 2 drives the multiple heaters 10 to rotate. When the heaters 10 rotate to the rear of the frame 1 and the auxiliary abutment rollers 7... When roller 37 disengages and the sensor switch 11 of heater 10 aligns with sensor 12, the sensor switch 11 activates to de-energize heater 10. When heater 10 rotates to the front of frame 1 and enters in front of auxiliary roller 4, and the sensor switch 11 of heater 10 aligns with sensor 23, the sensor switch 11 activates to energize heater 10, allowing multiple heaters 10 to be energized and de-energized in an orderly manner, reducing energy waste. The plastic flooring formed by the embossing roller 2 and auxiliary roller 37 passes under the cooler 21, with the patterned surface facing the cooler 21. The fan 22 runs and blows cold air through the cooler 21 onto the plastic flooring, causing the patterned surface of the plastic flooring to cool and solidify rapidly. Example 3
[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a plastic flooring embossing device includes a frame 1 and an embossing roller 2, the embossing roller 2 being rotatably mounted on the frame 1 via a rotating shaft 1; it also includes a sub-frame 1 3, a sub-abutment roller 1 4, a sub-abutment roller 2 5, a sub-frame 2 6, and a sub-abutment roller 3 7. The sub-frame 1 3 is mounted at the front of the frame 1, the sub-abutment roller 1 4 is rotatably mounted on the sub-frame 1 3 via a rotating shaft 2, and an embossing gap 1 is provided between the sub-abutment roller 1 4 and the embossing roller 2; the sub-abutment roller 2 5 is rotatably mounted on the frame 1 via a rotating shaft 3, and an embossing gap 2 is provided between the sub-abutment roller 2 5 and the embossing roller 2; the sub-frame 2 6 is mounted at the rear of the frame 1, the sub-abutment roller 3 7 is rotatably mounted on the sub-frame 2 6 via a rotating shaft 4, and an embossing gap 3 is provided between the sub-abutment roller 3 7 and the embossing roller 2; the embossing gaps 1, 2, and 3 gradually decrease; and an adjustment component is included. The system includes a slide table 16, a worm gear 17, a worm wheel 18, and a helical rack 19. The slide table 16 is slidably mounted on the frame 1 or the sub-frame 6. The rotating shaft 3 of the sub-roller 5 or the rotating shaft 4 of the sub-roller 7 is rotatably connected to the slide table 16. The worm gear 17 is rotatably mounted on the slide table 16 via a bracket. The worm wheel 18 is rotatably mounted on the slide table 16 and meshes with the worm gear 17. The helical rack 19 is mounted on the frame 1 or the sub-frame 6 and meshes with the worm wheel 18. Rotating the worm gear 17 drives the worm wheel 18 to rotate. The worm wheel 18 meshes with the helical rack 19, driving the slide table 16 to move along the frame 1 or the sub-frame 6, thereby adjusting the size of the gap 2 between the sub-roller 5 and the embossing roller 2 or the gap 3 between the sub-roller 7 and the embossing roller 2. The system has a simple structure and is easy to operate.
[0026] like Figures 1 to 6As shown, this utility model discloses a plastic flooring embossing device. During operation, the gap between the secondary abutment roller 2 (5) and the embossing roller 2, or the gap between the secondary abutment roller 3 (7) and the embossing roller 2, is adjusted as needed. Then, the end of the plastic flooring sequentially passes through the gap between the secondary abutment roller 4 (4) and the embossing roller 2, the gap between the secondary abutment roller 2 (5) and the embossing roller 2, and the gap between the secondary abutment roller 3 (7) and the embossing roller 2. This allows the embossing roller 2 to cooperate with the secondary abutment rollers 4, 5, and 7 to perform three embossing operations on the plastic flooring. As the embossing gaps 1, 2, and 3 gradually decrease, the pattern on the plastic flooring deepens through these three embossing operations, making the pattern more distinct and profound. Then... During the embossing process, multiple heaters 10 heat the embossing roller 2, causing the embossing roller 2 to heat the plastic flooring during embossing, making it easier for the plastic flooring to form patterns. Multiple rotary joints 8 are connected to an external cooling water system, allowing cold water to be input into the cooling water pipes inside the auxiliary roller 1 4, auxiliary roller 2 5, and auxiliary roller 3 7 through the multiple rotary joints 8, so that the auxiliary roller 1 4, auxiliary roller 2 5, and auxiliary roller 3 7 cool the back of the plastic flooring. Finally, the plastic flooring formed by the embossing roller 2 and auxiliary roller 3 7 passes under the cooler 21, with the patterned side facing the cooler 21. The fan 22 runs and blows cold air through the cooler 21 onto the plastic flooring, so that the patterned side of the plastic flooring cools and forms quickly.
