Abstract
The utility model belongs to the technical field of plastic extruders, more particularly relates to a hydraulic screen changing device on the plastic extruder. The hydraulic screen changing device is characterized in that a front mold plate and a rear mold plate with connecting grooves are arranged on both sides of a fixed frame; heating plates are arranged at the periphery of the front and the rear mold plates; a press cover is arranged in the middle hole of the two mold plates; a position-changing plate matched with the clearance thereof is arranged in the fixed frame between the front and the rear mold plates; one end of the position-changing plate is fixedly connected with a piston rod of an oil cylinder arranged on the fixed frame; two position-changing holes matched with the press cover position are arranged on the position-changing plates; a filter screen is arranged in the position-changing hole; and the inner end face of the press cover is in interference fit with the position-changing plate and is higher than the inner plane of the mold plate. The utility model has the advantages that the filter screen can be replaced at change work position in operation, thereby, improving the efficiency of the plastic extruder with simple structure and good tightness.
Description
Technical field:
The utility model belongs to the plastic extruder technical field, is specifically related to the hydraulic pressure net switching device on a kind of plastic extruder.
Background technology:
At present, the plastic extruder of domestic use generally adopts two kinds of draping modes, and a kind of is traditional flange opening type draping mode, must be to carry out under the state of shutting down, not only influence be produced, and the dismounting trouble, the workman operates under the condition of high temperature, and labour intensity is big, and efficient is low; Another kind is the old-fashioned net exchanging device that adopts four stations that change the outfit, and filter and front and back template directly press together, and contact area is too big, the resistance when having increased draping; Because four stations are made up of four different filters, size is difficult to accomplish unanimity, and fit clearance hour template occurs with filter is burnt to death very much easily, occurs leakage when the gap is too big again easily and expects phenomenon.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, can change filter screen, the hydraulic pressure net switching device of good airproof performance fast under non-stop-machine state.
The technical solution of the utility model is: a kind of hydraulic pressure net switching device is characterized in that: be provided with the front and back template that band connects groove in the fixed frame both sides, be provided with heating plate around the template of front and back, be provided with gland in the two template mesopores; Before and after be provided with transpositing plate with its matched in clearance in the fixed frame between the template, the piston rod of the oil cylinder that transpositing plate one end and fixed frame are provided with is connected, transpositing plate is provided with two transposition holes of matching with the gland position, is provided with filter screen in the hole of replacing; Be interference fit between the inner face of gland and the transpositing plate, and be higher than the template inner plane.
Owing to adopt technique scheme, transpositing plate drives two filter screens in the hole of replacing under the oil cylinder piston bar drives, change between station and the work station changing the outfit, thereby have under the non-stop-machine state and filter screen can be changed at the station that changes the outfit, improve plastic extruder efficient; And advantage simple in structure, good airproof performance.
Description of drawings:
Come the technical solution of the utility model is described in further details below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation that the utility model is removed front template;
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment:
With reference to figure 1--Fig. 3, a kind of hydraulic pressure net switching device is provided with the front and back template 1,6 that band connects groove in fixed frame 3 both sides, is provided with in heating plate 7, the two template mesopores around the template of front and back and is provided with gland 8; Be provided with transpositing plate 2 in the fixed frame 3 between the template of front and back with its matched in clearance, the piston rod 5 of the oil cylinder 4 that transpositing plate 2 one ends and fixed frame 3 are provided with is connected, transpositing plate 2 is provided with two transposition holes of matching with gland 8 positions, and transposition is provided with filter screen 9 in the hole; Between the inner face of gland 8 and the transpositing plate 2 is interference fit, and is higher than the template inner plane.During use, it is installed on the screw tube of plastic extruding machine port of export, front template fillistered joint barrel button, rear pattern plate fillistered joint discharging opening gets final product.
