Description

A rubber extruder

technical field

The utility model belongs to rubber industrial mechanical equipment, in particular to a rubber extruder. the

Background technique

Rubber extruder is a rubber industrial extruder used to extrude rubber semi-finished products or finished products with various cross-sectional shapes. It is mainly used for the production of wire and cable rubber strips and films. the

Since rubber is mainly prepared by extrusion and vulcanization, the temperature in the extrusion process needs to be kept at 100-160°C. In the rubber extruders in the prior art, the extrusion process is segmented temperature control, each extrusion The machine needs to be equipped with 4-5 mold temperature controllers, the cost is high, and in the case of long-term use at high temperature, the high-pressure oil pipe is prone to aging and oil leakage, polluting the environment, and it is difficult to implement temperature control, and it is difficult to achieve the ideal gelling effect. The rubber extruder needs to use more than 100 meters long steam pipeline for vulcanization. It is quite difficult to run the wires. It needs a two-story building as a site. It is inconvenient to operate and requires a large investment in equipment. Each investment is millions of yuan, and the maintenance rate is relatively high. . the

In addition, this kind of rubber can only be applied to sheet materials, and its versatility is not strong. the

Utility model content

The purpose of the utility model is to provide a rubber extruder which is energy-saving, environment-friendly, highly versatile and can reduce production cost and maintenance rate. the

The technical scheme adopted by the utility model to solve the technical problem is: a rubber extruder, including a base and a motor drive device, a feeding device, a temperature control device and a discharge device arranged in sequence on the frame, the described The feeding device is equipped with a sheet material input frame and a feeding cylinder at the same time. The temperature control device includes three heaters connected side by side. The inner layer and the outer layer of the heater are equipped with heating wires. The two ends of the heater A water inlet pipe and a water outlet pipe are respectively connected, and the water inlet pipe and the water outlet pipe are both connected to a constant temperature water tank, and the water inlet pipe is controlled by a solenoid valve.

Wherein, the feeding device is provided with a movable block with an "A"-shaped cross section. the

The beneficial effects of the utility model are: the feeding device is equipped with a sheet material input frame and a feeding cylinder at the same time, and the sheet material or pellets can be freely selected to enter, and each heater can reach the required temperature respectively by controlling the heating of the heating wire. By injecting water into the heater and circulating to take away excess heat, no boiler and mold temperature controller are needed, energy saving, environmental protection and easy operation. The entire equipment can be produced with an investment of only 300,000 yuan, which is 1/5 of the cost of traditional equipment, and the length of the site Only 25 meters is needed to meet the production needs. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail. the

Referring to Fig. 1, Fig. 2 and Fig. 3, a rubber extruder includes a base 1 and a motor drive device 2, a feeding device 3, a temperature control device 4 and a discharge device 5 arranged sequentially on the frame, Wherein, the described feeding device 3 is provided with sheet material input frame 31 and feeding cylinder 32 at the same time, and described feeding device 3 is provided with a movable block with "A" shaped section, and the described temperature control The device 4 includes three heaters 41 connected side by side. The inner and outer layers of the heater 41 are provided with heating wires. The two ends of the heater 41 are respectively connected with a water inlet pipe 45 and a water outlet pipe 46. The water pipes 46 are all connected to the constant temperature water tank, and the water inlet pipe 45 is controlled by a solenoid valve. the

The utility model can meet the different needs of the industry. The feeding device 3 is equipped with a sheet material input rack 31 and a feeding barrel 32 at the same time, and can choose to enter the sheet material or pellets at will. When using pellets, install the movable block , Inject the pellet in the feeding cylinder 32 and get final product, as when using the sheet material, the movable block is removed, and the roll sheet material is loaded on the sheet material input frame 31 and gets final product. the

When the heating wire of the temperature control device 4 is energized and heated, each heater 41 can reach different temperatures, which can melt the rubber. The maximum melting temperature of the rubber needs to be 160°C, while the maximum water temperature can only reach 100°C, and each heater 41 The temperature is not the same, when the temperature in a certain heater 41 is too high, water can be injected into the heater 41 through the water inlet pipe 45 and the water outlet pipe 46, and the heat is taken away by the circulation of running water and enters the constant temperature water tank. the

The utility model does not need a boiler and a mold temperature controller, is energy-saving, environmentally friendly, and easy to operate. The whole equipment can be produced with an investment of only 300,000 yuan, which is 1/5 of the cost of traditional equipment, and the site length is only 25 meters to meet the production needs. the

The above-mentioned embodiments only illustrate the principles and effects of the present utility model, as well as the partially used embodiments. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, some Deformation and improvement, these all belong to the protection domain of the present utility model. the
