Problems solved by technology
In the traditional structure, the position of the traction roller in the traction device is fixed, so that when the blown film passes through the gap between the traction rollers, its size depends on inflation and abandonment; it makes it difficult to control the overall size of the blown film, making the product quality unstable

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , figure 2 As shown, a traction mechanism of a film blowing machine includes a frame 1, a splint 2 and a traction roller, and the traction roller is fixed on the top of the splint in parallel. Described traction roller comprises driving roller 31 and extrusion roller 32, and driving roller 31 and extrusion roller 32 are arranged perpendicular to film traveling direction, leaves gap between driving roller 31 and extrusion roller 32 for film to pass through; Referring to Fig. 3, The driving roller 31 includes a first central shaft 311 and a first cylinder 312, the first central shaft is relatively fixed to the first cylinder, and the first central shaft is connected to the output end of the driving motor 4; the squeeze roller 32 includes a second The central shaft 321 and the second roller 322, the second roller can roll relative to the second ...

The invention discloses a traction mechanism of a film blowing machine. The traction mechanism comprises a machine frame, clamping plates and traction rollers; the traction rollers are parallelly fixed to the upper ends of the clamping plates and comprise the driving roller and the extrusion roller, the driving roller and the extrusion roller are perpendicular to the film feeding direction, and agap is reserved between the driving roller and the extrusion roller and used for allowing a film to pass; the two clamping plates are arranged in a reversed V shape and comprise the left clamping plate and the right clamping plate; the extrusion roller is elastically connected with a frame body of the machine frame; and the clamping plates can move up and down along the frame body, so that the width of the gap between the driving roller and the extrusion roller is changed. According to the traction mechanism of the film blowing machine, the clamping plates can move up and down by pushing screws on the lower portions of the clamping plates, the width of the gap between the driving roller and the extrusion roller is changed, and accordingly, the thickness of the film is adjusted. The traction mechanism of the film blowing machine is simple in structure, convenient to operate, low in cost and worthy of application and popularization.
Description
technical field [0001] The invention relates to a traction mechanism of a film blowing machine, which belongs to the technical field of plastic film production equipment. Background technique [0002] The film blowing machine heats and melts plastic particles and then blows them into a film, generally including a main frame, an extrusion device, a traction device, a heating device, a cooling device, a transfer device and a winding device. In the traditional structure, the position of the traction roller in the traction device is fixed, so that when the blown film passes through the gap between the traction rollers, its size depends on inflation and abandonment; it makes it difficult to control the size of the blown film, making the product quality unstable. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a traction mechanism for a film blowing machine. [0004] Technical solution: In order...
