Technical Field

[0001] This utility model relates to a PVC tablecloth positioning device, specifically a PVC tablecloth production positioning device, belonging to the field of PVC tablecloth processing technology. Background Technology

[0002] PVC tablecloths are a common type of plastic tablecloth. They have good waterproof and oil-proof properties, effectively preventing liquid penetration and oil stains. Accurate positioning is crucial in the production process of PVC tablecloths.

[0003] However, traditional PVC tablecloth production methods often rely on manual positioning, which is not only inefficient, but also prone to fatigue due to experience, leading to fluctuations in accuracy and inaccurate positioning. This results in unstable product quality and affects the precision of subsequent processes such as cutting and printing of the tablecloth.

[0004] To address these issues, we provide a PVC tablecloth production positioning device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a PVC tablecloth production positioning device. The specific technical solution is as follows: A PVC tablecloth production positioning device includes a processing table. An angle detection system, comprising at least two first optical sensors, is installed on the side of the processing table. A position detection system, comprising at least two second and third optical sensors, is also installed on the side of the processing table. A first movable frame and a second movable frame are installed on the upper part of the processing table. At least two first adjustment mechanisms are installed on the lower part of the first movable frame, and at least two second adjustment mechanisms are installed on the lower part of the second movable frame. The first and second adjustment mechanisms have the same structure, including a horizontal adjustment wheel and a vertical adjustment wheel. A telescopic cylinder is installed on the upper part of both the horizontal and vertical adjustment wheels.

[0006] Preferably, the processing table is connected to a smart control console on its side, the upper surface of the processing table is smooth, and a PVC tablecloth is placed on the surface of the processing table.

[0007] Preferably, the detection beams of the first, second, and third optical sensors are all illuminating the upper part of the processing table surface, and can illuminate the edge of the PVC tablecloth. The second and third optical sensors are located on adjacent sides of the processing table, respectively.

[0008] Preferably, the processing table is provided with track frames on both sides, and the lower ends of both sides of the first and second movable frames are provided with movable carriages. The movable carriages are provided with driving devices and rollers at their lower ends, and the movable carriages are located within the track frames.

[0009] Preferably, the outer ends of the horizontal adjusting wheel and the vertical adjusting wheel are provided with rubber sleeves, and the outer ends of the rubber sleeves are provided with anti-slip grooves. The upper end of the telescopic cylinder is connected to the first moving frame and the second moving frame.

[0010] Preferably, both the lateral and longitudinal adjusting wheels are equipped with intelligent control motors at their side ends. The drive end of the intelligent control motor is connected to the rotating shaft of the adjusting wheel. A spring connects the telescopic cylinder to the adjusting wheel, and a telescopic rod is installed inside the spring.

[0011] Preferably, the processing table has multiple sets of fixing holes, an air hood is provided at the lower end of the fixing holes, a vacuum pump is provided at the lower end of the processing table, and the vacuum pump is connected to the air hood through an air guide pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This PVC tablecloth production positioning equipment, equipped with a first adjustment mechanism and a second adjustment mechanism, can adjust the PVC tablecloth to a horizontal and vertical straight state with the assistance of a first optical sensor (meaning the edge of the PVC tablecloth is parallel to one edge of the processing table). With the assistance of a second optical sensor and a third optical sensor, it can adjust the PVC tablecloth to the positioning position. This device achieves automated positioning through the assistance of optical equipment and the drive of mechanical mechanisms, and can quickly and accurately adjust the PVC tablecloth to the required horizontal and vertical straight state and positioning position, reducing the time and error of manual adjustment, improving production efficiency, and reducing the labor intensity of workers.

[0013] 2. This PVC tablecloth production and positioning equipment is equipped with fixing holes, an air hood, and a vacuum pump. When the PVC tablecloth is placed on the processing table, the fixing holes are located at the bottom of the PVC tablecloth. When the vacuum pump is started, it draws air from the air hood through the air guide pipe, creating a negative pressure inside the fixing holes and the air hood. This allows the PVC tablecloth to be adsorbed and fixed, thus preventing it from moving during processing and ensuring processing accuracy. Furthermore, the negative pressure adsorption method will not cause scratches or wear on the surface of the PVC tablecloth, ensuring its aesthetics and integrity. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] Please see Figure 1 — Figure 5 The system includes a processing table 1, on which a PVC tablecloth is placed. The upper surface of the processing table 1 is smooth to facilitate the movement of the PVC tablecloth on the processing table 1.

[0018] An angle detection system is installed on the side of the processing table 1, which includes at least two optical sensors 2 to detect the angle of the PVC tablecloth. When the detection values ​​of the two optical sensors 2 are the same, it indicates that the PVC tablecloth is in a horizontal and vertical position on the processing table 1. A position detection system is installed on the side of the processing table 1, which includes at least two optical sensors 3 and 4. The optical sensors 3 and 4 are located on the two adjacent sides of the processing table 1, respectively, and are used to detect the distance of the PVC tablecloth from the edge of the processing table 1. The detection beams of the optical sensors 2, 3, and 4 are all illuminating the upper part of the table surface of the processing table 1, and can illuminate the edge of the PVC tablecloth, so as to determine the position of the PVC tablecloth on the processing table 1.

[0019] The upper end of the processing table 1 is provided with a first movable frame 5 and a second movable frame 6. Track frames 10 are provided on both sides of the processing table 1. A moving carriage 11 is provided at the lower end of both sides of the first movable frame 5 and the second movable frame 6. A driving device is provided inside the moving carriage 11, and rollers are provided at the lower end. The moving carriage 11 is located inside the track frame 10 and can move within the track frame 10, thereby driving the first movable frame 5 and the second movable frame 6 to move.

[0020] The lower end of the first movable frame 5 is provided with at least two first adjustment mechanisms 7, and the lower end of the second movable frame 6 is provided with at least two second adjustment mechanisms 8. The first adjustment mechanisms 7 and the second adjustment mechanisms 8 have the same structure, including a horizontal adjustment wheel 701 and a vertical adjustment wheel 702. The outer ends of the horizontal adjustment wheel 701 and the vertical adjustment wheel 702 are provided with rubber sleeves, and the outer ends of the rubber sleeves are provided with anti-slip grooves. The rubber sleeves are used to prevent scratches on the PVC tablecloth, and the anti-slip grooves are used to increase the friction between the adjustment wheel and the PVC tablecloth. The upper ends of the horizontal adjustment wheel 701 and the vertical adjustment wheel 702 are provided with telescopic cylinders 703. The upper ends of the telescopic cylinders 703 are connected to the first movable frame 5 and the second movable frame 6 to fix the telescopic cylinders 703. The telescopic cylinder 703 is used to adjust the height of the adjusting wheel. The side ends of the horizontal adjusting wheel 701 and the vertical adjusting wheel 702 are equipped with intelligent control motors 704. The drive end of the intelligent control motor 704 is connected to the rotating shaft of the adjusting wheel. When the intelligent control motor 704 is started, it can drive the adjusting wheel at the drive end to rotate. A spring 705 is connected between the telescopic cylinder 703 and the adjusting wheel. The spring 705 can be compressed and contracted, which not only makes the device suitable for PVC tablecloths of different thicknesses, but also provides downward pressure to the lower adjusting wheel. When the telescopic cylinder 703 is pressed down, it can make the adjusting wheel fit tightly against the PVC tablecloth. A telescopic rod is provided inside the spring 705 to restrain the lower adjusting wheel and prevent it from tilting.

[0021] Operating steps of the horizontal adjusting wheel 701 and the vertical adjusting wheel 702: The telescopic cylinder 703 is activated and pressed down, causing the horizontal adjusting wheel 701 or the vertical adjusting wheel 702 to move down and fit tightly against the upper end of the PVC tablecloth. Then, the intelligent control motor 704 is activated, causing the horizontal adjusting wheel 701 or the vertical adjusting wheel 702 at its drive end to rotate. Operating steps of the horizontal adjusting wheel 701 and the vertical adjusting wheel 702: The intelligent control motor 704 stops running, and then the telescopic cylinder 703 retracts, causing the horizontal adjusting wheel 701 or the vertical adjusting wheel 702 to lift away from the PVC tablecloth.

[0022] The processing table 1 is connected to a smart control console 9 on its side. The smart control console 9 is used to control the operation of the device. Multiple sets of fixing holes 12 are opened in the processing table 1. An air hood 13 is set at the lower end of the fixing hole 12. A vacuum pump 14 is set at the lower end of the processing table 1. The vacuum pump 14 is connected to the air hood 13 through an air guide pipe. When the vacuum pump 14 is started, it will draw air from the air hood 13 through the air guide pipe, which can create a negative pressure in the fixing hole 12 and the air hood 13, thereby adsorbing and fixing the PVC tablecloth.

[0023] The telescopic cylinder 703 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

[0024] When using this invention: The PVC tablecloth is placed on the processing table 1. The PVC tablecloth may tilt, causing the detection values ​​of the two optical sensors 2 to differ (e.g., ...). Figure 5 The intelligent control console 9 controls the longitudinal adjustment wheels 702 of the first adjustment mechanism 7 and the second adjustment mechanism 8 to run in different directions, which can generate two opposite forces on the PVC tablecloth, thereby causing the PVC tablecloth to rotate. When the detection values ​​of the two optical sensors 2 are exactly the same (regardless of the value), the intelligent control console 9 controls all the longitudinal adjustment wheels 702 to stop running. At this time, the PVC tablecloth is in a horizontal and vertical straight state. By inputting the positioning position of the PVC tablecloth on the processing table 1 through the intelligent control console 9, the distance from the edge of the PVC tablecloth to the second optical sensor 3 and the third optical sensor 4 can be determined, and the second optical sensor 3 and the third optical sensor 4 can determine the set detection length. The intelligent control console 9 controls the longitudinal adjustment wheels 702 in the first adjustment mechanism 7 and the second adjustment mechanism 8 to operate simultaneously and synchronously, exerting force on the PVC tablecloth and causing the PVC tablecloth to move longitudinally on the processing table 1. At this time, the detection value of the second optical sensor 3 will continuously change, while the value of the third optical sensor 4 remains unchanged. When the detection value of the second optical sensor 3 is the same as the set value, all the longitudinal adjustment wheels 702 stop operating, thus completing the longitudinal positioning of the PVC tablecloth. Similarly, by operating the transverse adjustment wheels 701 in the first adjustment mechanism 7 and the second adjustment mechanism 8 simultaneously and synchronously, when the detection value of the third optical sensor 4 is the same as the set value, the transverse positioning of the PVC tablecloth will be completed, thus completing the overall positioning of the PVC tablecloth. After the PVC tablecloth is positioned, the vacuum pump 14 is started to extract the air from the air hood 13, thereby adsorbing and fixing the PVC tablecloth through the fixing hole 12. This prevents the PVC tablecloth from moving during the processing. Then, the moving cart 11 drives the first moving frame 5 and the second moving frame 6 to move away from the upper end of the processing table 1, so as to avoid them from obstructing the processing equipment from processing the PVC tablecloth.
