Description

Technical Field

[0001] The utility model relates to the technical field of marking devices, in particular to a marking device for PVC pipe production. Background Art

[0002] The main component of PVC is polyvinyl chloride, which has strong heat resistance, toughness and ductility. The top layer of the surface film of PVC pipe is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC pipe is a synthetic material widely used in many fields. The marking device can mark the surface of various materials permanently. The mark can be a pattern, trademark or text. The marking device is needed in the production process of PVC pipe. The PVC pipe needs to be fixed during the marking process to improve processing efficiency.

[0003] For example, a marking device for PVC pipe production disclosed in the utility model with authorization announcement number CN217170257U drives the sliding block to move left and right through a power mechanism, and the connecting rod cooperates with the movement of the sliding block to drive the first wedge block to move left and right at the same time, and the first wedge block squeezes the second wedge block, so that the second wedge block drives the lifting rod and the extrusion plate to move up and down, and the inner wall of the PVC pipe mounted on the support pipe is supported by multiple groups of extrusion plates, thereby fixing the PVC pipe.

[0004] This prior art also has the following problems when used:

[0005] The device fixes the PVC pipe by moving multiple groups of extrusion plates outward and against the inner wall of the PVC pipe. Since the power mechanism drives the sliding block to move and drives the extrusion plates to move and against the PVC pipe at the same time, when the distance between one of the extrusion plates and the connecting rod is greater than the distance between the other extrusion plates and the connecting rod, the extrusion plate first contacts and squeezes the PVC pipe, and then the other extrusion plates find it difficult to continue to approach and contact the PVC pipe, thereby reducing the fixing effect of the device on the PVC pipe, resulting in the device having high requirements on the dimensional accuracy of the extrusion plates, the lifting rod, the first wedge block and the second wedge block. When the device fixes the PVC pipe with an uneven inner wall, when some extrusion plates contact and squeeze the PVC pipe, it is difficult for other extrusion plates to continue to approach and contact the PVC pipe, thereby reducing the fixing effect of the device on the PVC pipe with an uneven inner wall.

[0024] Example

[0025] Please refer to Figure 1-Figure 4 As shown, the utility model provides a marking device for PVC pipe production, including a bottom plate 1, an extrusion plate 15 and a support tube 23. The top surface of the bottom plate 1 is fixedly provided with a first L-shaped support plate 2 and a second L-shaped support plate 7. The bottom surface of the horizontal part of the first L-shaped support plate 2 is installed with an electric slide rail 3, and an electric slider 4 adapted to the electric slide rail 3 is installed on the electric slide rail 3. An electric telescopic rod 5 is fixedly installed on the bottom surface of the electric slider 4. A marking gun 6 is fixedly installed on the bottom surface of the output end of the electric telescopic rod 5. The electric telescopic rod 5 can be controlled to drive the marking gun 6 to move up and down to mark the PVC pipe. The electric slide rail 3 can be controlled to drive the electric slider 4 to move left and right, thereby driving the electric telescopic rod 5 and the marking gun 6 to move left and right. The support tube 23 is penetrated by the side of the vertical part of the second L-shaped support plate 7. The second L-shaped support plate 7 is fixedly connected to the support tube 23. A plurality of extrusion plates 15 are arranged on the outside of the support tube 23. The plurality of extrusion plates 15 squeeze the inner wall of the PVC pipe to fix the PVC pipe. The horizontal part of the second L-shaped support plate 7 is fixedly connected to the first L-shaped support plate 2.

[0026] like Figure 1-Figure 4As shown, an extrusion assembly is provided through the outside of the support tube 23, and the extrusion assembly is composed of a plug rod 13, a spring 14, a rubber anti-skid pad 16 and a connecting plate 18. The rubber anti-skid pad 16 and the plug rod 13 are fixedly provided on the outside and inside of the extrusion plate 15 respectively. The plug rod 13 passes through the support tube 23 and is slidably connected to the support tube 23. A connecting plate 18 is fixedly provided on the other side of the plug rod 13. A spring 14 is fixedly provided on the side of the extrusion plate 15 close to the plug rod 13. The side of the spring 14 away from the extrusion plate 15 is fixedly connected to the support tube 23. The extrusion plate 15 and the rubber anti-skid pad 16 move inward at the same time, so that the PVC tube can be conveniently set on the outside of the support tube 23. The spring 14 is compressed to complete the P After the VC tube is sleeved, the extrusion plate 15 and the rubber anti-skid pad 16 are released to allow the spring 14 to push the extrusion plate 15 and the rubber anti-skid pad 16 to move outward at the same time to squeeze the inner wall of the PVC tube, thereby fixing the PVC tube. The rubber anti-skid pad 16 can increase the friction between the extrusion plate 15 and the inner wall of the PVC tube, thereby improving the fixing effect of the PVC tube. When one group of extrusion plates 15 and rubber anti-skid pads 16 squeezes the PVC tube, it does not affect the other extrusion plates 15 and rubber anti-skid pads 16 to continue to approach the PVC tube, thereby reducing the dimensional accuracy requirements of the extrusion assembly, improving the fixing effect of the PVC tube with an uneven inner wall, and extending the service life of the device.

A support column 8 is fixedly arranged on the top surface of the base plate 1, a servo motor 9 is fixedly installed on the top surface of the support column 8, a first bevel gear 10 is fixedly arranged on the top surface of the output end of the servo motor 9, a second bevel gear 11 is meshed above the first bevel gear 10, a threaded rod 12 is fixedly arranged on the side of the second bevel gear 11, the threaded rod 12 passes through a support tube 23, and one end of the support tube 23 away from the second bevel gear 11 is rotatably connected to the inner wall of the support tube 23 through a bearing, a threaded sleeve 20 is threadedly connected to the outer side of the threaded rod 12, a connecting rod 19 is hinged on the upper and lower sides of the threaded sleeve 20, and the connecting rod 19 is away from the threaded sleeve One end of 20 is hinged with a pull plate 17, and the pull plate 17 is arranged between the inner wall of the support tube 23 and the connecting plate 18. The insertion rod 13 passes through the pull plate 17 and is slidably connected to the pull plate 17. The movement of the pull plate 17 can drive the connecting plates 18 to move closer to or away from each other, thereby driving the extrusion plate 15 and the rubber anti-skid pad 16 to move closer to or away from each other. The front and rear sides of the threaded sleeve 20 are slidably connected with symmetrical guide plates 21, and a fixing rod 22 is fixedly arranged on the outside of the guide plate 21. The end of the fixing rod 22 away from the guide plate 21 is fixedly connected to the inner wall of the support tube 23. Running the servo motor 9 drives the threaded rod 12 to rotate, which can drive multiple pull plates 17 to move inward or outward at the same time, thereby driving multiple groups of extrusion plates 15 and rubber anti-skid pads 16 to move inward or outward at the same time, which is convenient for the device to install and fix the PVC pipe.

When the compression of the spring 14 reaches the maximum, the PVC pipe sleeve is set outside the support pipe 23 to complete the installation of the PVC pipe. After installation, the servo motor 9 is controlled to drive the first bevel gear 10 to rotate in the opposite direction, thereby driving the pull plate 17 to move outward at the same time until the pull plate 17 moves back to its original position. During the movement of the pull plate 17, the spring 14 pushes the extrusion plate 15 to drive the extrusion plate 15, the rubber anti-skid pad 16 and the insertion rod 13 to move outward at the same time. The movement of the insertion rod 13, the extrusion plate 15 and the rubber anti-skid pad 16 does not affect the movement of the pull plate 17. The movement of a single group of insertion rods 13, the extrusion plate 15 and the rubber anti-skid pad 16 does not affect the movement of other insertion rods 13, the extrusion plate 15 and the rubber anti-skid pad 16, until each group of extrusion plates 15 and rubber anti-skid pads 16 contact and squeeze the inner wall of the PVC pipe, thereby fixing the PVC pipe. When the PVC pipe needs to be removed, the servo motor 9 is controlled to drive the pull plate 17 to move inward at the same time until the compression of the spring 14 reaches the maximum, so that the PVC pipe can be moved away from the support pipe 23. The threaded sleeve 20 never separates from the guide plate 21 during the movement.

After the installation of the PVC tube is completed, the servo motor 9 is controlled to drive the first bevel gear 10 to rotate in the opposite direction, thereby driving the pull plate 17 to move outward at the same time until the pull plate 17 moves back to its original position. During the movement of the pull plate 17, the spring 14 pushes the extrusion plate 15 to drive the extrusion plate 15, the rubber anti-skid pad 16 and the insertion rod 13 to move outward at the same time until each group of extrusion plates 15 and rubber anti-skid pads 16 contact and squeeze the inner wall of the PVC tube, thereby fixing the PVC tube.
