Description

Technical Field

[0001] This utility model relates to the field of PVC flooring sheet pressing technology, and in particular to a PVC flooring sheet pressing and molding machine. Background Technology

[0002] PVC flooring is a type of floor covering material made of polyvinyl chloride. It has excellent properties such as wear resistance, stain resistance, slip resistance, antibacterial properties, and fire resistance, and is widely used in homes, offices, hospitals, schools, sports venues, and other places. Specifically, it is made from polyvinyl chloride and its copolymer resin as the main raw materials, with the addition of fillers, plasticizers, stabilizers, colorants, and other auxiliary materials, and is produced on a sheet continuous substrate through coating processes or calendering, extrusion, or compression processes.

[0003] Patent specification CN217968432U discloses a PVC flooring sheet pressing and molding machine, including a conveying device. A first fixed frame is fixed to the top left side of the conveying device. A threaded column passes through the top of the first fixed frame, and the threaded column is threadedly connected to the through-hole of the first fixed frame. A folding plate is rotatably connected to the bottom of the threaded column, and a pressure cylinder body is rotatably connected to the surface of the folding plate. A turntable is fixed to the top of the threaded column, and a handle is fixed to the top of the turntable. This invention can adjust the height of the pressure cylinder according to the processing thickness of the PVC flooring, and the adjustment precision is higher, improving the processing accuracy of PVC flooring. It can also clean impurities on the surface of the PVC flooring, improving the processing quality of the flooring.

[0004] However, in implementing the relevant technology, the PVC flooring sheet compression molding machine designed above has the following problems: Although the height of the press cylinder can be adjusted in the existing technology, it requires manual adjustment, which is relatively troublesome to operate. Moreover, when the device is working, the vibration of the machine causes the sheet and the press cylinder to collide, resulting in damage. In view of this, a PVC flooring sheet compression molding machine is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PVC flooring board pressing and molding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a PVC flooring sheet pressing and molding machine, including a conveying device, a dustproof box is provided at the top of the conveying device, and a partition is fixed in the middle of the interior of the dustproof box. A mounting plate is provided on one side of the dustproof box at the top of the conveying device, and a pressing mechanism is provided inside the mounting plate.

[0007] The pressing mechanism includes a motor, which is embedded in one side of the outer wall of the mounting plate. The power output end of the motor is connected to a worm gear. One end of the worm gear, which protrudes from the outer wall of the mounting plate, is connected to a worm wheel. A threaded rod protrudes from the inside of the worm wheel. A movable plate is slidably connected to the outer wall of the end of the threaded rod that protrudes from the worm wheel. Multiple damping springs are embedded at the bottom of the movable plate. A sliding plate is connected below the damping springs. A pressing cylinder is rotatably connected between two axes below the sliding plate. The damping springs elastically push the sliding plate, causing the pressing cylinder to press firmly onto the plate. The elasticity of the damping springs prevents excessive pressing, which could cause the transmission equipment to fail to deliver or cause collisions.

[0008] As a further description of the above technical solution: the threaded rod and the mounting plate form a locking structure, and the threaded rod is threadedly connected to the moving plate. The threaded rod is locked to the mounting plate at the top end to prevent shaking or detachment from the mounting plate during rotation, which would affect the movement of the moving plate.

[0009] As a further description of the above technical solution: the two axial outer walls of the sliding plate are fixed with limit blocks, and a support rod is inserted into one end of the limit block and protrudes from it. A telescopic spring is sleeved on the lower part of the outer wall of the support rod. When the sliding plate slides, it slides stably along the mounting plate through the limit blocks to avoid deviation. At the same time, it works with the support rod to further improve the stability during sliding. When the sliding plate drives the pressing cylinder to press the plate, the telescopic spring has a certain elasticity to avoid excessive pressing and friction, which would affect the conveying.

[0010] As a further description of the above technical solution: a cleaning mechanism is provided at the front end of the internal partition of the dustproof box. The cleaning mechanism includes a blower, which is embedded in one side of the top of the dustproof box. The output end of the blower is connected to a ventilation pipe. One end of the ventilation pipe that enters the dustproof box is connected to an air outlet. The blower draws in external air and blows it into the dustproof box. The air outlet is guided by the ventilation pipe to blow the dust to both sides, causing the dust to move to both sides. At the same time, the dustproof box prevents the dust from spreading too much and affecting the staff.

[0011] As a further description of the above technical solution: the cleaning mechanism also includes a connecting frame, which is fixed to the outside of the air outlet, and a cleaning roller is rotatably connected between the two axes at the bottom of the connecting frame. When the board is conveyed to the range of the connecting frame, it touches the cleaning roller and the cleaning roller cleans the board, thereby further improving the cleanliness of the board.

[0012] As a further description of the above technical solution: the connecting frame has a U-shaped structure, and the connecting frame is fixedly connected to the air outlet. The air outlet passes through and is fixed on the connecting frame, which facilitates airflow from the middle to both sides to clean the board.

[0013] As a further description of the above technical solution: the connecting frame inside the dustproof box at the top of the transmission equipment has ash inlets on both sides, and the outer walls of the transmission equipment are slidably connected to collection shells. When dust moves to both sides, it enters the ash inlets and falls into the collection shells for unified collection. The collection shells are periodically removed to clean the dust.

[0014] This utility model has the following beneficial effects:

[0015] This utility model discloses a PVC flooring sheet pressing and molding machine. A motor drives a worm gear to rotate, which in turn pushes a threaded rod to adjust the height of a moving plate. A damping spring then elastically pushes a sliding plate, which in turn drives a pressing cylinder to press the sheet material. The adjustable height eliminates the need for manual adjustment, improving convenience. It is suitable for sheets of different thicknesses. The damping spring's elasticity prevents excessive pressing from affecting the conveying equipment's sheet material transport. It also provides shock absorption, preventing mechanical vibration from causing the pressing cylinder to collide with the sheet material.

[0016] This utility model discloses a PVC flooring board pressing and molding machine. Through the blowing equipment, ventilation pipe and air outlet, it is easy to form gas to blow the dust on the board to both sides, and with the help of cleaning rollers, the dust is scraped away, improving the cleanliness of the board. The dust on both sides enters the collection shell through the dust inlet and is collected. The collection shell is periodically pulled out of the transmission equipment for easy collection and cleaning of the dust. Attached Figure Description

[0023] Reference Figure 1-4 The present invention provides a PVC flooring sheet compression molding machine: including a transmission device 1, a dustproof box 2 is provided at the top of the transmission device 1, a partition 3 is fixed in the middle of the interior of the dustproof box 2, a mounting plate 4 is provided on one side of the dustproof box 2 at the top of the transmission device 1, and a pressing mechanism 5 is provided inside the mounting plate 4.

[0024] The pressing mechanism 5 includes a motor 501, which is embedded in one side of the outer wall of the mounting plate 4. The power output end of the motor 501 is connected to a worm gear 502. One end of the worm gear 502 protrudes from the outer wall of the mounting plate 4 and is connected to a worm wheel 503. A threaded rod 504 protrudes from the inside of the worm wheel 503. A movable plate 508 is slidably connected to one end of the threaded rod 504 protruding from the outer wall of the worm wheel 503. Multiple damping springs 505 are embedded at the bottom end of the movable plate 508. A sliding plate 506 is connected below the damping springs 505. A pressing cylinder 507 is rotatably connected between two axes below the sliding plate 506. The sliding plate 506 is pushed by the damping springs 505 to press the pressing cylinder 507 against the plate. The elasticity of the damping springs 505 prevents excessive pressing, which could cause the transmission device 1 to fail to deliver or to be bumped.

[0025] As a further implementation of the above technical solution: the threaded rod 504 and the mounting plate 4 form a locking structure, the threaded rod 504 is threadedly connected to the moving plate 508, and the top of the threaded rod 504 is locked to the mounting plate 4 to avoid shaking or detachment from the mounting plate 4 during rotation, which would affect the movement of the moving plate 508.

[0026] As a further implementation of the above technical solution: Limiting blocks 6 are fixed to the outer walls of the two axes of the sliding plate 506. A support rod 7 extends out from one end of the limiting block 6 into the mounting plate 4. A telescopic spring 8 is sleeved on the lower part of the outer wall of the support rod 7. When the sliding plate 506 slides, it slides stably along the mounting plate 4 through the limiting block 6 to avoid deviation. At the same time, it works with the support rod 7 to further improve the stability during sliding. When the sliding plate 506 drives the pressing cylinder 507 to press the plate, the telescopic spring 8 has a certain elasticity to avoid excessive pressing and excessive friction, which would affect the conveying.

[0027] In practical implementation, when the conveying device 1 drives the conveying of the sheet material, the worm gear 502 drives the worm wheel 503 under the drive of the motor 501, causing the threaded rod 504 to rotate and push the moving plate 508 down. The damping spring 505 elastically pushes the sliding plate 506, causing the pressing cylinder 507 to roll and abut against the sheet material. This is suitable for pressing sheet materials of different thicknesses. The elasticity and shock absorption of the damping spring 505 prevent excessive compression that could lead to excessive friction and affect the conveying of the sheet material. At the same time, it also prevents vibration that could cause collisions. In addition, the telescopic spring 8 on the support rod 7 elastically supports the limiting block 6, further improving elasticity and preventing excessive compression.

[0028] As a further implementation of the above technical solution: a cleaning mechanism 9 is provided at the front end of the internal partition 3 of the dustproof box 2. The cleaning mechanism 9 includes a blower 901, which is embedded in one side of the top of the dustproof box 2. The output end of the blower 901 is connected to a ventilation pipe 902. One end of the ventilation pipe 902 that enters the dustproof box 2 is connected to an air outlet 903. The blower 901 draws in external air and blows it into the dustproof box 2. The air outlet 903 is guided by the ventilation pipe 902 to blow the dust to both sides, so that the dust moves to both sides. At the same time, the dustproof box 2 prevents the dust from spreading too much and affecting the staff.

[0029] As a further implementation of the above technical solution: the cleaning mechanism 9 also includes a connecting frame 904, which is fixed to the outside of the air outlet 903. A cleaning roller 905 is rotatably connected between the two axes at the bottom of the connecting frame 904. When the board is conveyed to the range of the connecting frame 904, it touches the cleaning roller 905 and the cleaning roller 905 cleans the board, thereby further improving the cleanliness of the board.

[0030] As a further implementation of the above technical solution: the connecting frame 904 has a U-shaped structure. The connecting frame 904 is fixedly connected to the air outlet 903. The air outlet 903 passes through and is fixed on the connecting frame 904, which facilitates airflow from the middle to both sides to clean the board.

[0031] As a further implementation of the above technical solution: the connecting frame 904 inside the dustproof box 2 at the top of the transmission equipment 1 has ash inlets 10 on both sides, and the outer walls of the transmission equipment 1 are slidably connected to the collection shells 11. When the dust moves to both sides, it enters the ash inlets 10 and falls into the collection shells 11 for unified collection. The collection shells 11 are periodically removed to clean the dust.

[0032] In practice, air is drawn in by the blower 901 and supplied to the air outlet 903 through the ventilation pipe 902. With the connection frame 904 fixed, the air is blown to both sides of the board to remove dust from the board. At the same time, the cleaning roller 905 scrapes the dust off the sliding board to further improve the cleanliness of the board. The dust enters the collection shell 11 through the dust inlet 10 for easy collection and cleaning in the later stage. The partition 3 prevents the dust from spreading too much.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
