The pressing piston 31 is driven by a second driving device 32 to press the material up and down in the feeding barrel 21. The second driving device 32 is preferably a motor.

[0031] Furthermore, the bottom plate of the feed barrel 21 is fixed to the frame 1 by a first swing angle seat 231 and a second swing angle seat 232. A rotating shaft 24 is provided on the bottom plate of the feed barrel 21. The feed barrel 21 can be opened by pulling the rotating shaft 24. A swing angle plate 22 is provided on the frame 1 to limit the swing angle of the feed barrel 21, which is convenient for material filling. A discharge seat 25 is provided below the feed barrel 21. The feed barrel 21 is connected and fixed to the discharge seat 25 by a feed barrel buckle 26. Preferably, there are two feed barrel buckles 26.

[0032] Furthermore, the interior of the discharge seat 25 is in the shape of an inverted truncated cone. After passing through the discharge seat 25, the material is extruded into a cylindrical shape and enters the molding device 4. The discharge port of the discharge seat 25 is directly connected to the feed port of the molding device 4, so that the loss of materials during transportation can be reduced. An extrusion baffle 401 is provided at the connection between the discharge port of the discharge seat 25 and the feed port of the molding device 4. When quantitative extrusion is performed, the extrusion baffle 401 can block the discharge port of the discharge seat 25 and the feed port of the molding device 4.

[0033] The forming device 4 includes an extrusion cylinder 403, the upper opening of the extrusion cylinder 403 is connected to the feeding device 2, a feeding channel 411 is provided in the extrusion cylinder 403 and is connected to the upper opening, after the material enters the extrusion cylinder 403 from top to bottom, a piston extrusion push rod 404 is provided on one side of the feeding channel 411, the feeding channel 411 is preferably cylindrical, the piston extrusion push rod 404 is preferably a cylinder matched with the feeding channel 411, the head of the piston extrusion push rod 404 is provided with an extrusion piston 412, the tail of the piston extrusion push rod 404 is provided with a first groove 414, the first groove 414 is clamped on the push plate 40 5, the first sliders 406 are connected to the two sides of the push plate 405, nuts 407 are arranged on the push plate 405, and the first driving device 413 is connected to the nuts 407 through the push screw 408. The first driving device 413 is preferably a motor, which drives the push plate 405 and the piston push rod 404 to reciprocate along the track in the cylindrical feeding channel, so that the material can pass through the cylindrical feeding channel at a uniform speed, and because the push screw 408 drives the piston extrusion push rod, the precision is high and stable, which solves the problem that the material texture is weak and the viscosity is large, and it is difficult to accurately feed the material.

[0034] Furthermore, a second groove 416 is provided on the other side of the cylindrical feeding channel, and the die seat 409 is clamped on the second groove 416, so that the movement trajectory of the material is changed by the die seat 409. The die 410 is connected below the die seat, and the outlet of the die 410 is in the shape of a desired product. In the present embodiment, the outlet of the die 410 is a rectangle with chamfered corners on all sides.

[0035] Furthermore, after the forming device 4 processes the material, the control system determines whether the material reaches a preset length or a preset weight. When the material parameter reaches the preset value, the cutting device 5 cuts the material.

[0036] Furthermore, after the material is cut by the cutting device 5, the control system measures the length or weighs the obtained material, and the result is fed back to the control system to adjust the cutting device 5. If the length or weight of the obtained material exceeds the preset value, the operating speed of the cutting device 5 will be increased. Similarly, if the length or weight of the obtained material does not reach the preset value, the operating speed of the cutting device 5 will be reduced to achieve the purpose of controlling the length and weight of the material.

[0037] Furthermore, the cutting device 5 includes a tool 51, the tool 51 is provided with a tool head 52, and a tool holder pad 53 is provided behind the tool head 52.

A tool connecting block 54 is provided at the tail of the tool 51 and is connected to a nut of a driving device. The driving device is preferably a motor. A second slider 55 is provided on the tool 51, and the second slider 55 moves along the slide rail of the tool holder fixing block 56 fixed on the frame under the drive of the motor.

[0038] The working principle of the utility model is as follows:

[0039] When it is necessary to cut the silicone, first open the feed barrel buckle 26, use the rotating shaft 24 to rotate the feed barrel 21 to open it, put the material into the feed barrel 21, then close the feed barrel 21, and buckle the feed barrel buckle 26; then turn on the power to cut the silicone, and the silicone raw material enters the molding device 4 under the extrusion of the pressing piston 31. At this time, the extrusion baffle 401 is in an open state. When the molding device 4 is full of material, the extrusion baffle 401 is in a closed state, and enters the die seat 409 under the extrusion of the piston extrusion push rod 404, and then extrude the required shape according to the outlet shape of the die 410; when the set weight or length is reached, the driving device drives the cutting device 5 to cut the material; when the control system detects that the material does not reach the set weight or length, adjust the running speed of the cutting device 5; finally, collect the cut silicone strips into the relevant material tray for further processing.
