Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe production equipment, in particular to a PVC pipe anti-shake device for an extruder. Background Art

[0002] PVC pipe is a pipe made of polyvinyl chloride resin. After being treated with stabilizers and lubricants, plastic pipes are widely used in drainage, wastewater treatment, chemical transportation, heating liquid and coolant transportation, food processing, ultra-pure liquid transportation, mud transportation, gas transportation, compressed air and vacuum system applications. When actually producing PVC pipes, an extruder is required to complete the extrusion molding. The extruder needs to be equipped with an anti-shake device to avoid the shaking of the molded PVC pipe. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses an anti-shake device for extruded plastic pipes with a bulletin number of CN212826713U, comprising a base, a track, a first support plate, a second support plate, a through hole, a step hole, a vertical plate, a horizontal groove, a fixed rod, a fixed block, a wedge block, a connecting rod, a support leg, a tension spring, a spring and a ball. When in use, the position of the through hole corresponds to the position of the discharge port of the extrusion molding equipment, the extruded plastic pipe enters the through hole of the first support plate, passes through a plurality of through holes in sequence, and then enters the step hole of the second support plate. The small hole diameter of the step hole is smaller than the plastic pipe, and the plastic pipe pushes the second support plate to make it on the track. When the second support plate moves to the left, the connecting rod drives the wedge block to move, so that the fixed block is disengaged from the fixed rod, and the corresponding first support plate moves to the left to support the plastic pipe, so that the plastic pipe is supported by the support plate at every certain distance to ensure its stability. When the second support plate moves to the leftmost position and cannot go back any further, the plastic pipe is cut off to prevent it from continuing to push the second support plate forward to cause damage to the equipment or damage to the plastic pipe. The track length can be customized according to the length of the plastic pipe, so that the cut-off length of the plastic pipe meets the length requirement.

[0004] In the above utility model, the PVC tube needs to pass through a plurality of through holes. The plurality of through holes prevent the PVC tube from passing through. However, the sizes of the plurality of through holes are fixed, and the sizes of the PVC tube are various. To replace the plate structure with through holes of different sizes, it is necessary to produce plate structures of various sizes. This method will increase the investment cost of the utility model. At the same time, the cutting length of the PVC tube can only be carried out when the second support plate cannot move further. The PVC tube cannot be cut into the expected length, which reduces the practicality of the use of the utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the extruded PVC tube contacts the blocking plate, the extruded PVC tube can be cut off. By setting the blocking plate, the extrusion length of the PVC tube can be controlled, thereby improving the practicality of the PVC tube anti-shake device for an extruder.
