Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PVC sheet processing equipment, and in particular to an automatic PVC sheet traction machine. Background Technology
[0002] PVC sheets are sheet-like plastic products made from polyvinyl chloride resin as the base material, with various additives added, mixed and plasticized, and then processed by calendering or extrusion. They have properties such as insulation and acid and alkali resistance, and are widely used.
[0003] In the molding, conveying, and subsequent processing of PVC sheets, a traction machine is required to move the sheets at a constant speed and with stable tension. An automatic PVC sheet traction machine can drive a traction roller assembly via a motor, using the friction between the roller surface and the sheet to continuously pull the sheet, thereby ensuring smooth sheet conveying, meeting the requirements of efficient production and precise processes, and ensuring stable sheet quality.
[0004] However, existing automatic PVC sheet traction machines have the following shortcomings:
[0005] In the existing technology, the traction roller group of the automatic PVC sheet traction machine is inconvenient to adjust and can usually only perform efficient traction operations on PVC sheets of fixed thickness. However, due to the difference in the thickness of PVC sheets, the traction roller group is difficult to adapt flexibly, which can easily cause uneven force on the sheet during the traction process, resulting in wrinkles, displacement or even breakage of the sheet, which seriously affects the yield rate of products and the continuity of production.
[0006] Therefore, we propose an automatic PVC sheet traction machine to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this invention is to provide an automatic PVC sheet traction machine. By using a motor drive combined with a threaded assembly transmission, the spray assembly can be moved towards the drum. The telescopic frame can be moved vertically by an electric push rod, which can position a set of nozzles inside the drum. At this time, the spray assembly is driven by a water pump to work, which can achieve effective spray cleaning of the inner and outer walls of the drum, thereby solving the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automatic PVC sheet traction machine, comprising an operating table, four support columns fixedly connected to the outer wall of the operating table, sliders slidably embedded in the inner walls of the four support columns, a top plate fixedly connected between the tops of the four support columns, an adjusting screw threadedly connected to the inner wall of the top plate, a throttle fixedly connected to the top of the adjusting screw, a first bearing fixedly sleeved on the outer wall of the adjusting screw, fixed brackets fixedly connected to the outer wall of the operating table and the outer wall of the first bearing, two sets of second bearings fixedly inserted into the inner walls of the two fixed brackets, rotating rollers fixedly inserted between the interiors of the four sets of second bearings, a conveyor belt fixedly sleeved between the outer walls of the two sets of rotating rollers, and a drive motor fixedly connected to one side of the outer wall of two of the two sets of rotating rollers.
[0009] Preferably, two fixing plates are fixedly installed on the top of each operating table, and guide rollers are movably inserted between the inner surfaces of the two fixing plates.
[0010] Preferably, an adsorption box is fixedly connected to the top of the operating table, and two adsorption tubes are fixedly connected to the outer wall of the adsorption box.
[0011] Preferably, the input ends of both adsorption tubes are fixedly connected to adsorption covers, and an exhaust fan is fixedly inserted into the inner wall of the adsorption box.
[0012] Preferably, a filter box is fixedly connected to one side of the outer wall of the adsorption box.
[0013] Preferably, a primary filter is movably inserted into the inner wall of the filter box.
[0014] Preferably, a medium-efficiency filter is movably inserted into the inner wall of the filter box.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, through the interaction of the various components of the device, the two conveyor belts can flexibly and stably clamp PVC sheets of different thicknesses by utilizing the transmission of the threaded assembly and the stable guiding effect of the sliding assembly.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: an automatic PVC sheet traction machine, including an operating table 1, four support columns 2 fixedly connected to the outer wall of the operating table 1, sliders 3 slidably embedded in the inner wall of each of the four support columns 2, a top plate 4 fixedly connected between the tops of the four support columns 2, an adjusting screw 5 threadedly connected to the inner wall of the top plate 4, a throttle 6 fixedly connected to the top of the adjusting screw 5, a first bearing 7 fixedly sleeved on the outer wall of the adjusting screw 5, a fixed bracket 8 fixedly connected to the outer wall of the operating table 1 and the outer wall of the first bearing 7, two sets of second bearings 9 fixedly inserted into the inner wall of each of the two fixed brackets 8, rotating rollers 10 fixedly inserted between the interiors of the four sets of second bearings 9, a conveyor belt 11 fixedly sleeved between the outer walls of the two sets of rotating rollers 10, and a drive motor 12 fixedly connected to one side of the outer wall of two of the two sets of rotating rollers 10.
[0026] The overall effect of Embodiment 1 is that, during use, when the thickness of the PVC sheet changes, the operator can first turn the handle 6, which drives the adjusting screw 5 to rotate. Because the outer wall of the adjusting screw 5 is threadedly connected to the inner wall of the top plate 4, the rotation of the adjusting screw 5 will cause the upper fixed bracket 8 to move vertically. Furthermore, since the outer walls of the four sliders 3 are fixedly connected to the top fixed bracket 8, the four sliders 3 ensure the stability of the movement of the fixed bracket 8. At this time, PVC sheets of different thicknesses are placed between the two conveyor belts 11, and then guided into the winding device via the guide roller 14. Then, the rotation... The throttle 6 moves the top fixed bracket 8 downward, firmly clamping the PVC sheet between the two conveyor belts 11. Then, the two drive motors 12 are started, driving the two guide rollers 14 to rotate, which in turn causes the two conveyor belts 11 to rotate. The rotation of the two conveyor belts 11 can pull the PVC sheet to move smoothly. Through this traction method, PVC sheets of different thicknesses can be pulled stably and efficiently, thus avoiding traction problems caused by differences in sheet thickness. This significantly improves the applicability and versatility of the automatic PVC sheet traction machine, ensuring the continuity of production and the stability of product quality.
[0027] Example 2, as Figure 2-4 As shown, two fixed plates 13 are fixedly installed on the top of the operating table 1. Guide rollers 14 are movably inserted between the inner walls of the two fixed plates 13. An adsorption box 15 is fixedly connected to the top of the operating table 1. Two adsorption tubes 16 are fixedly connected to the outer wall of the adsorption box 15. Adsorption covers 17 are fixedly connected to the input ends of the two adsorption tubes 16. An exhaust fan 18 is fixedly inserted into the inner wall of the adsorption box 15. A filter box 19 is fixedly connected to one side of the outer wall of the adsorption box 15. A primary filter 20 is movably inserted into the inner wall of the filter box 19. A medium-efficiency filter 21 is movably inserted into the inner wall of the filter box 19.
[0028] The overall effect of Embodiment 2 is as follows: During the PVC sheet traction process, the exhaust fan 18 is first started. After the exhaust fan 18 is running, it generates a strong suction force. Subsequently, this suction force causes a negative pressure environment to be formed inside the adsorption box 15. This negative pressure is conducted through the two adsorption tubes 16, causing the two adsorption hoods 17 to generate adsorption force, thereby adsorbing the upper and lower surfaces of the PVC sheet during the traction process, ensuring the cleanliness of the upper and lower surfaces of the PVC sheet. The dust, debris and other impurities captured during the adsorption process then enter the filter box 19 through the exhaust fan 18. Inside the filter box 19, the pre-filter 20 first intercepts larger particles of impurities, and then the medium-efficiency filter 21 further removes fine particles and some harmful gases, thereby purifying the air, preventing impurities from escaping again, ensuring the cleanliness of the production environment and the normal operation of the equipment.
[0029] The working principle of the entire equipment is as follows: When the thickness of the PVC sheet to be pulled changes, the traction device needs to be adjusted accordingly. The operator first turns the handle 6, which drives the adjusting screw 5 to rotate. Since the outer wall of the adjusting screw 5 is connected to the inner wall of the top plate 4 through a threaded connection, according to the principle of thread transmission, the rotation of the adjusting screw 5 will be converted into a vertical linear motion, thereby driving the upper fixed bracket 8 to move smoothly in the vertical direction. During the movement of the fixed bracket 8, the slider 3 slides along the preset groove, ensuring the stability and accuracy of the movement of the fixed bracket 8. At this time, PVC sheets of different thicknesses are introduced between the two conveyor belts 11. Under the guidance of the guide rollers 14, the sheets are conveyed to the winding device in an orderly manner. The operator turns the handle 6 again, causing the top fixed bracket 8 to move downward until the PVC sheet is firmly clamped between the two conveyor belts 11. The two drive motors 12 are started, and the drive motors 12 output power, driving the two guide rollers 14 to rotate, thereby driving the two conveyor belts 11 to rotate synchronously. The friction between belt 11 and the PVC sheet provides stable traction, allowing the PVC sheet to move smoothly. Simultaneously, the exhaust fan 18 is activated, generating strong suction at high speed. This suction creates a negative pressure environment inside the adsorption box 15, which is transmitted through two adsorption pipes 16 to two adsorption hoods 17, causing the hoods 17 to generate strong adsorption force. The adsorption hoods 17 are positioned on the upper and lower sides of the PVC sheet, enabling comprehensive adsorption of both surfaces during the traction process, effectively removing dust and impurities adhering to the sheet surface. The adsorbed dust, impurities, and other pollutants are then drawn into the filter box 19 through pipes by the airflow generated by the exhaust fan 18. Inside the filter box 19, the pre-filter 20 first functions, intercepting larger particles of dust, debris, and other impurities, providing initial purification of the airflow. The airflow after pre-filtering continues to pass through the medium-efficiency filter 21, which further removes fine particles and some harmful gases, providing more refined purification of the airflow.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
