Description

Technical Field

[0001] The utility model relates to the technical field of butyl rubber extrusion equipment, in particular to butyl rubber equal-amount feeding extrusion equipment. Background Art

[0002] Butyl rubber extrusion equipment is a kind of equipment used to produce butyl rubber products. Its extrusion process refers to the process of heating and mixing the butyl rubber material, and then pressurizing and extruding it in the extrusion head of the extruder to form the desired product. This process requires the control of the temperature, pressure, speed and other parameters of the extruder to ensure the quality and production efficiency of the product. The main products of butyl rubber extrusion equipment include butyl tape, foamed butyl tape, automotive shock absorber pad, automotive windshield butyl tape, high-speed rail glass butyl rubber sealing strip, building glass curtain wall butyl rubber strip, aluminum foil butyl rubber waterproof roll, etc. These products are widely used in automobiles, construction, high-speed rail and other fields, playing an important role in sealing, shock absorption, waterproofing, etc.

[0003] In the extrusion process of butyl rubber, the design of the feeding system is also critical. Since butyl rubber is relatively soft and sticky, it is easy to overflow into the rolling bearing of the feeding seat during the extrusion process, causing equipment damage. Therefore, the feeding system is often designed in a funnel shape, which can feed block or roll rubber, and is equipped with a double wrist conjugate wheel for forced feeding to prevent material breakage and instability of pressure in the extruder barrel.

[0004] Since butyl rubber is relatively soft and has high viscosity, when the butyl rubber raw material is put into the feed hopper of the extrusion equipment, the butyl rubber blocks will stay in the feed hopper for a long time, making it inefficient for the butyl rubber blocks to enter the extrusion tube. In view of this, the present application proposes a butyl rubber equal-amount feeding extrusion equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a butyl rubber equal-amount feeding extrusion equipment, which has the advantages of quickly pressing butyl rubber blocks into an extrusion tube, etc., and solves the problem that because butyl rubber is relatively soft and has high viscosity, when the butyl rubber raw material is put into the feed hopper of the extrusion equipment, the butyl rubber blocks will stay in the feed hopper for a long time, resulting in low efficiency in the butyl rubber blocks entering the extrusion tube.

[0006] In order to achieve the above-mentioned purpose of quickly pressing the butyl rubber block into the extrusion tube, the utility model provides the following technical solutions: a butyl rubber equal amount feeding extrusion equipment, comprising a mounting base, a transmission box is fixedly installed on the top of the mounting base, an extrusion tube is fixedly installed on one side of the transmission box, a feeding hopper is fixedly installed on the top of the extrusion tube, a mounting bracket is fixedly installed on the top of the mounting base, a hydraulic cylinder is fixedly installed on the top of the mounting bracket, and a feeding head is fixedly installed on the movable end of the hydraulic cylinder facing downward;

[0007] The material discharge head comprises a dome plate fixedly mounted on the movable end of the hydraulic cylinder, a pressing rotating shaft is rotatably mounted on the bottom of the dome plate, a pressing head is fixedly mounted on the bottom end of the pressing rotating shaft, and the pressing head is adapted to the material discharge hopper.

[0008] Furthermore, a transmission gear is fixedly installed on the surface of the pressed-in rotating shaft, a pressed-in power shaft is rotatably installed between the dome plate and the pressed-in head, and a power gear meshing with the transmission gear is fixedly installed on the surface of the pressed-in power shaft.

[0009] Furthermore, a press-in motor is fixedly mounted on the top of the dome plate, and an output shaft of the press-in motor is fixedly connected to the top end of the press-in power shaft.

[0010] Furthermore, a guide rod is fixedly installed on the top of the dome plate, and a limit block is fixedly installed on the top end of the guide rod extending to the top above the mounting bracket.

[0011] Furthermore, an extrusion power shaft is rotatably mounted on the inner side wall of the transmission box, a driving sprocket is fixedly mounted on the surface of the extrusion power shaft, a driven shaft is rotatably mounted on the inner side wall of the transmission box, a driven sprocket is fixedly mounted on the surface of the driven shaft, and the driving sprocket and the driven sprocket are connected by chain transmission.

[0014] Compared with the prior art, the utility model provides a butyl rubber equal-amount feeding extrusion device, which has the following beneficial effects:

[0015] The butyl rubber equal-amount feeding and extrusion equipment has a mounting bracket arranged on the top of a mounting base, and a hydraulic cylinder arranged on the mounting bracket. The hydraulic cylinder drives a feeding head to be pressed into a feeding hopper, and the butyl rubber is pressed into an extrusion tube. Meanwhile, a pressing motor drives the pressing head to rotate, so that the pressing process is smoother, and the problem that the butyl rubber block stays in the feeding hopper for a long time when the butyl rubber raw material is put into the feeding hopper of the extrusion equipment due to the butyl rubber being relatively soft and having high viscosity is solved, so that the butyl rubber block is not efficient in entering the extrusion tube.
