Problems solved by technology

Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products, which are widely used in the field of decoration and construction. However, in the existing PVC pipe processing process, the extruder The PVC pipe at the outlet needs to be manually supported and cut to prevent the PVC pipe from being exposed too long and causing breakage, but manual support and cutting can easily lead to uncertain cutting lengths, and the cutting quality cannot be guaranteed

Embodiment 1

[0023] Such as figure 1 , 3 Among them, a guide cutting device for PVC extruder, including a guide mechanism and a cutting mechanism, the guide mechanism includes a frame 1, a support plate is provided in the frame 1, and the cutting mechanism includes a top plate 2 and a bottom plate 3, and the top plate 2 and the bottom plate 3 A cutting machine 6 is provided between them.

[0024] The top plate 2 is provided with a first hydraulic cylinder 4, the first push rod 5 of the first hydraulic cylinder 4 passes through the top plate 2 and extends between the top plate 2 and the bottom plate 3, and the first push rod 5 is provided with a cutting machine 6.

Embodiment 2

[0026] Such as figure 2 , on the basis of Embodiment 1, the bottom of the frame 1 is provided with a third hydraulic cylinder 12, the third push rod 13 of the third hydraulic cylinder 12 is set vertically upward and the third push rod 13 is provided with a second support Plate 14 , third support plates 15 are provided on both inner sides of the frame 1 , and the third support plates 15 are connected to the inner sides of the frame 1 through springs 16 .

[0027] The bottom plate 3 of the cutting mechanism is provided with a second hydraulic cylinder 7, the second push rod 11 of the second hydraulic cylinder 7 is provided with a first support plate 8, and the first support plate 8 and the second support plate 14 are located at the same on the level.

[0028] The first support plate 8 , the second support plate 14 and the third support plate 15 are all arc-shaped plates, and the concave arc surface is set towards the inside of the guide mechanism and the cutting mechanism.

...

Embodiment 3

[0033] On the basis of Example 2, the first support plate 8 , the second support plate 14 and the third support plate 15 are all provided with guide wheels 17 near the discharge port of the extruder.

[0034] With the above-mentioned structure, a better supporting effect is achieved for the guidance of the output PVC pipe, which can avoid the pipe breakage caused by the sagging of the output part; the controller controls the precise cutting of the pipe to ensure that the length of the pipe in the same batch is uniform and the product quality is guaranteed. .

Abstract

A guide cutting device for a PVC extruder comprises a guide mechanism and a cutting mechanism, wherein the guide mechanism comprises a frame in which a supporting plate is arranged; the cutting mechanism consists of a top plate and a bottom plate; and a cutter is arranged between the top plate and the bottom plate. With the adoption of the device having the abovementioned structure, a PVC pipe canbe automatically cut after being conveyed out, and moreover, the stability of the output PVC pipe section can be ensured, so that the PVC pipe processing efficiency and quality can be improved.

Description

technical field [0001] The invention relates to the field of PVC building material processing, in particular to a guide cutting device for a PVC extruder. Background technique [0002] PVC pipes are cheap, and different additives can be added according to different uses. PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products, which are widely used in the field of decoration and construction. However, in the existing PVC pipe processing process, the extruder The PVC pipe at the outlet needs to be manually supported and cut to prevent the PVC pipe from being exposed too long and causing breakage. However, manual support and cutting can easily lead to uncertain cutting lengths, and the cutting quality cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is a guide cutt...
