Description

Technical Field

[0001] The invention relates to an extruder, in particular to an automatic rubber material preparation extruder. Background Art

[0002] At present, rubber molding machines are a very common machine. Rubber molding machines generally inject fully mixed rubber materials first, and then extrude them through molds. The mixing process is carried out by a mixer, but the pressure of the rubber material provided by a conventional mixer is relatively low, and the viscosity of the rubber material is relatively high, which is not conducive to the flow of the rubber material. As the structure of existing rubber products becomes more and more complex, and the requirements for the fine structure become more stringent, the flow channels in the mold become more complex. However, the existing mixed rubber materials are often difficult to completely fill the flow channels. This is because local solidification will occur during the circulation process, resulting in gaps in the mold flow channels, which makes the rubber product incomplete, making it difficult to completely form and fail to achieve the expected structure.

[0003] In order to solve the above problems, currently, an air compressor is generally used to pressurize the mixed rubber material, so that the rubber material can quickly and completely enter the flow channel of the mold. However, the maximum injection pressure of the rubber material after the air compressor is pressurized is only 10Kg / cm 2 , it is still difficult to produce qualified rubber products for complex molds. Summary of the invention

[0004] The purpose of the invention is to provide a rubber automatic material preparation extruder, which can automatically mix and pressurize rubber materials.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a rubber automatic material preparation extruder, comprising a base, a lower support frame, a mounting seat and an upper support frame, wherein the lower support frame is arranged on the top of the base, the mounting seat is arranged on the top of the lower support frame, and the upper support frame is arranged on the top of the mounting seat, and a driving structure is arranged on the top of the upper support frame, and the bottom of the driving shaft at the bottom of the driving structure is connected with an extrusion column; a receiving cavity is formed in the middle of the extrusion column, and the bottom of the receiving cavity is open; a feeding pipe is connected to the outside of the extrusion column, and the feeding pipe is connected to the receiving cavity; a mixing part is installed in the middle of the mounting seat, a mixing cavity is formed in the middle of the mixing part, a multi-way joint is arranged at the bottom of the mixing part, at least two output pipes are connected to the multi-way joint, and a control valve is arranged at the end of the output pipe;

[0006] The driving structure can drive the extrusion column to reciprocate in the vertical direction; when the rubber material is injected into the containing cavity through the feeding pipe, the extrusion column can enter the mixing cavity and squeeze the rubber material into the multi-way joint.

[0007] Preferably, a connecting head is provided at the bottom of the driving shaft, and the extrusion column is threadedly connected to the bottom of the connecting head.

[0008] Preferably, the driving structure is a cylinder or a hydraulic pump.

[0009] Preferably, the bottom of the extrusion column is threadedly connected to an adapter, the bottom end of the adapter is threadedly connected to an injection head, the extrusion column, the adapter and the injection head are interconnected; a sealing ring is provided on the outer wall of the adapter.

[0010] Preferably, the top and bottom of the adapter are provided with inwardly concave connecting grooves, and the extrusion column and the injection head are all threadedly fixed to the connecting grooves; the bottom of the injection head is a structure that is wide at the top and narrow at the bottom.

[0011] Preferably, a ball bearing is arranged between the top of the injection head and the connecting groove.

[0012] Preferably, a joint is connected to the bottom of the mixing part, and the multi-way joint is connected to the joint through a pipeline.

[0013] Preferably, a downwardly recessed installation groove is formed at the bottom of the joint, and the bottom of the installation groove is funnel-shaped.

[0014] Preferably, the mixing portion and the mounting groove are connected by threads.

[0015] Preferably, the multi-way connector is a three-way connector, a four-way connector or a five-way connector.

[0016] In the above technical scheme, the working process of the automatic rubber preparation extruder provided by the present invention is as follows: first, the extrusion column is driven to move downward by the driving structure so that the bottom of the extrusion column enters the mixing chamber, and the driving of the driving structure is suspended at this time; then, multiple rubber materials (such as two rubber materials) are injected into the accommodating chamber through the feeding pipe, and the rubber materials enter the mixing chamber along the accommodating chamber, and at the same time, the extrusion column is driven to reciprocate up and down in the mixing chamber to achieve the effect of mixing and preparing the rubber materials; once the mixing effect is achieved, the extrusion column is continued to be driven downward to squeeze the rubber material into the multi-way joint; wherein, by controlling the control valve, the rubber material can be squeezed into different molds through the output pipe for rubber molding, thereby realizing the effect of one mixing structure feeding multiple molding mechanisms; more importantly, the maximum injection pressure of the rubber material in the output pipe can be as high as 1500Kg / cm 2 , so that the rubber material can quickly fill all the flow channels of the mold, thereby improving the qualification rate of rubber products.

[0017] On the contrary, once the rubber injection is completed, the extrusion column and the mixing part can be separated by the driving structure, and the extrusion column and the mixing part can be cleaned and maintained. Therefore, the device also has the advantages of easy operation and maintenance.

[0039] The driving structure 9 can drive the extrusion column 5 to reciprocate in the vertical direction; when the rubber material is injected into the accommodating chamber 13 through the feeding pipe 12, the extrusion column 5 can enter the mixing chamber 14 and squeeze the rubber material into the multi-way joint 16.

[0040] The working process of the above-mentioned automatic rubber preparation extruder is as follows: first, the extrusion column 5 is driven downward by the driving structure 9 so that the bottom of the extrusion column 5 enters the mixing chamber 14, and the driving of the driving structure 9 is suspended at this time; then, a plurality of rubber materials (such as two rubber materials) are injected into the accommodating chamber 13 through the feeding pipe 12, and the rubber materials enter the mixing chamber 14 along the accommodating chamber 13, and at the same time, the extrusion column 5 is driven to reciprocate up and down in the mixing chamber 14 to achieve the effect of mixing and preparing the rubber materials; once the mixing effect is achieved, the extrusion column 5 is continued to be driven downward to squeeze the rubber materials into the multi-way joint 16; wherein, by controlling the control valve 10, the rubber materials can be squeezed into different molds through the output pipe 11 for rubber molding, thereby realizing the effect of one mixing structure feeding multiple molding mechanisms; more importantly, the maximum injection pressure of the rubber materials in the output pipe 11 can be as high as 1500Kg / cm 2 , so that the rubber material can quickly fill all the flow channels of the mold, thereby improving the qualified rate of rubber products.
