For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0029] Figure 1 to Figure 7 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 7 The utility model is further described.

[0030] An extrusion device for rubber and plastic insulation materials includes a device body 1, which includes an extrusion barrel and a heating device. It is a conventional structure in the prior art and is not described in detail. A rotating rod 7 is rotatably installed in the device body 1, and a conveying auger is fixed on the rotating rod 7. An L-shaped base is installed at the bottom of the device body 1, and a motor 2 is installed on the side of the L-shaped base. One end of the rotating rod 7 extends outside the device body 1 and is installed on the output shaft of the motor 2.

[0031] A plurality of extrusion heads 6 are arranged on the left side of the equipment body 1. The shapes and specifications of the plurality of extrusion heads 6 are different, and the corresponding products produced are also different. For example, rubber and plastic insulation boards, rubber and plastic insulation pipes, insulation sealing strips, etc. can be extruded. A rotating installation mechanism compatible with the plurality of extrusion heads 6 is arranged on the equipment body 1. The rotating installation mechanism includes a fixed block 8 fixedly installed on the side of the equipment body 1, and a circular groove is provided on the side of the fixed block 8. A cylinder 9 is detachably connected in the circular groove, and a circular plate 5 is fixedly sleeved on the cylinder 9. The plurality of extrusion heads 6 are all installed on the circular plate 5. A flow hole is provided on the side of the equipment body 1, and a rectangular tube 10 is installed on the flow hole. The side of the circular plate 5 is provided with a plurality of rectangular grooves that can be compatible with the rectangular tube 10. The rectangular grooves correspond to the extrusion heads 6 one by one and are connected.

[0032] The cylinder 9 is installed in cooperation with the fixed block 8 through a rotating fixed assembly. The rotating fixed assembly includes two movable holes opened on the cylinder 9, at least two sliding rods are installed in the two movable holes, an L-shaped block 11 is slidably sleeved on the sliding rod, a circular cavity connected to the circular groove is opened on the fixed block 8, the sides of the two L-shaped blocks 11 extend into the circular cavity and are respectively installed with incomplete gears 13, an annular rack 14 is installed on the inner wall of the circumference of the circular cavity, the two incomplete gears 13 can be engaged with the annular rack 14, and the sides of the two L-shaped blocks 11 are provided with elastic units, which can drive the incomplete gears 13 to be tightly engaged with the annular rack 14. Specifically, the incomplete gear 13 can be engaged with the annular rack 14 or cancelled by the L-shaped block 11, so as to fix and limit the cylinder 9 to prevent it from rotating and moving.

[0033] By means of the above structure, the cylinder 9 can be rotated and pulled by the fixing block 8, and the rotation and pulling of the cylinder 9 can cause the circular plate 5 to rotate and move, so that the corresponding rectangular grooves of different extrusion heads 6 are aligned and contacted with the rectangular tube 10. At the same time, the cylinder 9 can be quickly fixed by rotating the fixing assembly to prevent it from rotating and moving, thereby facilitating the replacement of the extrusion head 6.

[0034] The elastic unit includes a spring 12 installed on the side of the L-shaped block 11, and the other end of the spring 12 is installed on the inner wall of the side of the movable hole. The above structure facilitates the L-shaped block 11 to quickly reset.

[0035] The sides of the two L-shaped blocks 11 are both installed with ropes 15, the other ends of the two ropes 15 are both installed with rings, and the sides of the cylinder 9 are installed with rods 16 that are compatible with the two rings.

[0036] The above structure is convenient for limiting the position of the L-shaped block 11. Specifically, when in use, the collar can be sleeved on the sleeve rod 16, and the sleeve rope 15 can pull the L-shaped block 11 to avoid resetting under the action of the spring 12.

[0037] A feed box 3 is fixedly provided on the top of the equipment body 1. Two crushing rods 17 are rotatably installed in the feed box 3. A plurality of crushing knives 18 are provided on the two crushing rods 17. The two crushing rods 17 are installed in cooperation with the rotating rod 7 through a transmission mechanism.

[0038] The transmission mechanism includes a first sprocket 19 fixedly mounted on the rotating rod 7, one end of one of the breaker rods 17 extends to the outside of the feed box 3 and is installed with a second sprocket 20, a chain 21 is meshed and installed on the first sprocket 19 and the second sprocket 20, a first circular gear 22 is also fixedly mounted on the breaker rod 17 on which the second sprocket 20 is installed, one end of the other breaker rod 17 extends to the outside of the feed box 3 and is installed with a second circular gear 23, and the first circular gear 22 is meshed with the second circular gear 23.

[0039] Specifically, the rotation of the rotating rod 7 will cause one of the crushing rods 17 to rotate through the first sprocket 19, the second sprocket 20 and the chain 21. The rotation of one of the crushing rods 17 will cause the other crushing rod 17 to rotate in the opposite direction through the first circular gear 22 and the second circular gear 23, so that the crushing knife 18 crushes the rubber and plastic insulation raw material.

[0040] The diameter of the first sprocket 19 is greater than the diameter of the second sprocket 20. The diameter ratio of the first sprocket 19 to the second sprocket 20 allows the crushing rod 17 to rotate faster, so that the rotating rod 7 drives the crushing rod 17 to rotate quickly while rotating, thereby ensuring crushing efficiency.

[0041] The top of the fixed block 8 is provided with a slot, the top of the slot is provided with an insert block, and the side of the insert block is provided with a protective shell 4. The protective shell 4 can protect other extruder heads 6, and the setting of the insert block and the slot facilitates the movement of the protective shell 4.

[0042] In summary: when the utility model is in use, firstly, the rubber and plastic insulation raw materials are poured into the feed box 3, and at the same time, the motor 2 is started during the pouring, and the output of the motor 2 drives the rotating rod 7 to rotate, and the rotating rod 7 rotates to rotate the first sprocket 19, and the rotation of the first sprocket 19 causes the second sprocket 20 to rotate rapidly through the chain 21, and the rotation of the second sprocket 20 causes one of the breaker rods 17 to rotate, and the rotation of one of the breaker rods 17 causes the first circular gear 22 to rotate, and the rotation of the first circular gear 22 causes the second circular gear 23 to rotate in the opposite direction, and the reverse rotation of the second circular gear 23 causes the other breaker rod 17 to rotate in the opposite direction, and the two breaker rods 17 drive the breaker blades 18 to rotate in the opposite direction, thereby further crushing and mixing the raw materials, and then the raw materials fall into the equipment body 1, and at the same time, the rotating rod 7 rotates to push the heated and molten rubber and plastic insulation raw materials through the conveying auger, and then extrude it from one of the extrusion heads 6 through the rectangular tube 10, thereby producing a product with a set shape of the extrusion head 6;

[0043] When it is necessary to change different extruder heads 6 to produce different rubber and plastic products, hold the two L-shaped blocks 11 and bring them close to each other. The two L-shaped blocks 11 are forced to move, which will cause the two incomplete gears 13 to move. The movement of the two incomplete gears 13 will cancel the clamping connection with the annular rack 14, and then pull the cylinder 9 outward. The movement of the cylinder 9 will cause the circular plate 5 to move, and then the rectangular tube 10 will be separated from one of the rectangular grooves. After separation, rotate the circular plate 5 to align the rectangular groove on the other extruder head 6 with the rectangular tube 10. After alignment, push the cylinder 9 to reset it. The movement and reset of the cylinder 9 will reset the circular plate 5. The reset of the circular plate 5 will cause the rectangular tube 10 to enter another rectangular groove and fit the inner wall. At the same time, when the cylinder 9 is reset, the two incomplete gears 13 are not blocked by the circular groove. At this time, the spring 12 quickly resets it. The reset of the incomplete gear 13 will be clamped with the annular rack 14 again, thereby limiting and fixing the cylinder 9. When replaced, the previous extruder head 6 can be maintained or cleaned.
