Problems solved by technology

If the distance between the front beam and the rear beam is too long, the entire stretching device needs to be very long, occupying a large area, and it is difficult to place it in the factory building
[0006] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: it is not suitable for plastic stretched nets that require a large amount of transverse stretching

Embodiment 1

[0044] The embodiment of the present application discloses a water-bath stretching machine for stretching a net. refer to figure 1 and figure 2 , The stretching line includes an unwinding mechanism 1, a water bath stretching machine and a winding mechanism 2. The water-bath stretching machine includes a machine base 3, a water-bath preheating pool 4, a guide roller group, a water-bath heat preservation pool 5, and a stretching mechanism 6. Wherein the unwinding mechanism 1, the water bath preheating pool 4, the water bath heat preservation pool 5 and the winding mechanism 2 are arranged in sequence. The stretching mechanism 6 is installed on the machine base 3 , and the stretching mechanism 6 is located in the water bath heat preservation tank 5 . The set of guide rollers is used to guide the stretched net to pass through the water bath preheating pool 4 and the stretching mechanism 6 in sequence. The water bath preheating pool 4 and the water bath heat preservation pool ...

Embodiment 2

[0059] The difference between embodiment 2 and embodiment 1 is that, referring to Figure 5 and Figure 6 , two stretched cymbals 9 form stretched cymbals group 19. There are several stretching cymbal groups 19 arranged at intervals along the feeding direction of the stretching wire. The guide roller set also includes a driving roller 28, which is arranged between two adjacent stretching cymbal sets 19. Stretch net passes around transmission roller 28 earlier after the stretching cymbal group 19 of wherein front, then is wound on the stretching cymbal group 19 of rear, thereby fully utilizes the peripheral circumference of stretching cymbal 9.

[0060] When in use, the number of stretched cymbal groups 19 to be used can be selected according to actual working conditions. If the width of the stretched net needs to be stretched laterally is larger, then select multiple groups of stretched cymbals 19, so that the stretched net is laterally stretched to the required width after...

Embodiment 3

[0062] The difference between embodiment 3 and embodiment 1 is that, referring to Figure 7 and Figure 8 , also includes two second drive assemblies 20, one stretch cymbal 9 corresponds to one second drive assembly 20. The second driving assembly 20 is used to drive the stretched cymbal 9 to rotate relative to the base 3 . To adjust the width of the feed end of the stretching mechanism 6 and the width of the discharge end, it can be better applicable to more working conditions.

[0063] Specifically, the limiting roller 8 near the feeding end of the stretched cymbal 9 is set as the first roller. The limiting wheel 17 on the first roller is slidably connected to the first roller along the axial direction. The second driving assembly 20 includes a screw rod 21 , a push block 22 and a servo motor 23 . The screw mandrel 21 is parallel to the first roller and the screw mandrel 21 is screwed on the machine base 3, the body of the servo motor 23 is fixedly installed on the base,...

Abstract

The invention relates to the field of plastic net material processing equipment, in particular to a water bath stretcher for stretching a net. Comprising a water bath preheating pool, a guide roller set and a stretching mechanism, the stretching mechanism comprises two stretching cymbals symmetrically arranged along the vertical plane and a first driving assembly used for driving the stretching cymbals to rotate along the center lines of the stretching cymbals, and the side, facing the other stretching cymbal, of each stretching cymbal is an obliquely-arranged guide face; and pricking needles are arranged on the outer wall of the stretching cymbal along the peripheries of the guide surfaces, and the pricking needles are used for fixing the stretching net relative to the peripheries of the guide surfaces and enabling the stretching net to move forwards along with rotation of the stretching cymbal. Due to the fact that the periphery of the stretching cymbal is round, the stretching net can be transversely stretched to the required width after passing through a longer path, and the stretching net is not prone to being broken in the stretching process. And meanwhile, the space in the length direction is not large, so that the device is more suitable for the plastic stretching net with higher requirement on the transverse stretching amount.

Description

technical field [0001] The present application relates to the field of plastic mesh processing equipment, in particular to a water-bath stretching machine for stretching mesh. Background technique [0002] At present, the processing technology of stretched plastic mesh is as follows: the plastic raw material is heated and melted in the extruder, and extruded by a screw into a special rotating head with inner and outer dies with several small holes. The molten plastic flows through the pores of the die to form two molten filaments. Through the rotation of the machine head, the two strands of material filaments converge at one point intermittently to form a network, and then after being stretched transversely, they are cooled and shaped into a network. [0003] The transverse stretching process is generally realized by a stretching machine. For example, the patent with the publication number CN202225436U discloses an adjustable plastic mesh lateral stretching device, a heat ...
