Description

TECHNICAL FIELD

[0001] The utility model relates to the production equipment field, in detail is a kind of engineering tyre open mill glue supply device. BACKGROUND

[0002] It is known that open mill is a kind of commonly used rubber mixing equipment in tire production field, and the glue supply amount needs to be controlled according to different glue amount requirements in the rubber mixing process. The commonly used glue supply amount control mode is to stop glue supply intermittently. The commonly used mode for intermittent glue supply is to stop the glue supply device, which generally adopts manual operation to cut off the glue material, which is not only low in efficiency but also prone to safety accidents. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a kind of engineering tyre open mill glue supply device, which can automatically pull off the glue material.

[0004] The utility model discloses a kind of engineering tyre open mill glue supply device, two rotating rollers are arranged in parallel, glue supply conveyor belt is sleeved on the two rotating rollers, two open mill cylinders with roll surface tangency are arranged below the front end of glue supply conveyor belt, it is characterized in that, a parallel strip-shaped channel steel is arranged at the front end of glue supply conveyor belt, a fixed plate is welded on the front side of channel steel, a locking nut is fixed on the fixed plate, the end of the telescopic rod of air cylinder is hexagonal structure, the hexagonal structure of telescopic rod end is embedded in the head of internal hexagon bolt, telescopic rod and internal hexagon bolt joint part are sleeved with annular sleeve, annular sleeve two ends are welded together with telescopic rod and internal hexagon bolt, the rod of internal hexagon bolt is screwed in locking nut.

[0005] The utility model has the advantages that manual operation is not needed, and the glue material is pressed by the piston rod of cylinder, and the glue material is pulled off by the rotation of open mill cylinder. BRIEF DESCRIPTION OF DRAWINGS

[0006] The utility model will be further described below in combination with drawings and examples.

[0007] Figure 1 The structure diagram of the utility model.

[0008] Figure 2 It is the schematic diagram of the connection of cylinder and internal hexagon bolt.

[0009] In the figure, 1 is telescopic rod, 2 is annular sleeve, 3 is internal hexagon bolt, 4 is cylinder, 5 is open mill cylinder, 6 is glue material, 7 is fixed plate, 8 is locking nut, 9 is channel steel, 10 is glue supply conveyor belt, 11 is rotating roller. DETAILED DESCRIPTION

[0010] In the figure, the utility model parallelly sets up two rotating rollers 11, the rubber conveying belt 10 is sleeved on the two rotating rollers 11, the rubber conveying belt 10 front end is below provided with two roll surface tangent's opening mill roller 5, the rubber conveying belt 10 front end is equipped with a parallel strip-shaped channel steel 9, the channel steel 9's front side is welded with fixed plate 7, the fixed plate 7 is fixed with locking nut 8, the telescopic rod 1 end of air cylinder 4 is hexagonal structure, the telescopic rod 1 end hexagonal is embedded in the head of internal hexagon bolt 3, the telescopic rod 1 and internal hexagon bolt 3 joint part are sleeved with circular ring sleeve 2, the circular ring sleeve 2 both ends are welded together with telescopic rod 1 and internal hexagon bolt 3 respectively, the internal hexagon bolt 3 rod is spun in locking nut 8.

[0011] The rubber conveying belt 10 runs and sends the rubber material 6 between the two opening mill roller 5, the rubber material 6 is mixed between the two opening mill roller 5, when reaching certain rubber amount or setting time, the rubber conveying belt 10 stops automatically, the telescopic rod 1 of air cylinder 4 extends and passes through the channel steel 9 and presses the rubber material 6 on the rubber conveying belt 10, at this time, the opening mill roller 5 normally runs and pulls the rubber material 6 to break. When the rubber amount on the opening mill roller 5 is below certain degree or reaches setting time, the telescopic rod 1 of air cylinder 4 drives the channel steel 9 to exit, the rubber conveying belt 10 starts to run and supplies rubber, reaches the purpose of intermittent rubber supply.
