[0002] Extruder is a mechanical equipment frequently used in the cable industry. The main extrusion raw material used is plastic granule masterbatch. When in use, the plastic granule masterbatch is put into the extruder. The extruder is equipped with a push screw and a heating device.

Various products can be extruded by setting the shape of the extrusion head mold.

[0003] When producing rubber sealing rings, the masterbatch needs to be transported to the inside of the extruder to produce the rubber sealing rings. However, the existing feeding device does not have a quantitative device, so it is impossible to accurately know how much masterbatch is used to produce how many rubber sealing rings, and because the thickness of the rubber ring sealing ring is different, the required weight of the masterbatch is also different.

[0020] The movement of the arc block 56 to the left will increase the downward movement time of the sliding disk 34, so that more raw materials can be injected into the quantitative box 24. Similarly, the movement of the arc block 56 to the right will reduce the raw materials injected into the quantitative box 24. The motor 22 is powered by an external power supply, and the trigger switch 55 is set between the external power supply and the trigger switch 55. The motor adopts a motor with controllable speed.

[0021] The base plate 1 is fixedly connected with an extruder body 6 , the quantitative box 24 is fixedly connected with a material guide pipe 7 , and the material guide pipe 7 is fixedly connected with a control switch 8 ; the control switch 8 is used to control the sealing and opening of the material guide pipe 7 .

[0022] The support frame 21 is fixed on the base plate 1 , and one end of the pulling rope 25 is fixedly connected to the winding wheel 23 ; the rotation of the winding wheel 23 will cause the pulling rope 25 to be wound around the winding wheel 23 .

[0023] The sliding shell 31 is fixed on the base plate 1 , and the sliding plate 34 is slidably connected to the sliding shell 31 ; the sliding plate 34 can slide inside the sliding shell 31 .

[0024] The quantitative box 24 is disposed on the support plate 33 , and the first spring 35 is located at the bottom of the sliding plate 34 ; the first spring 35 is used to push the quantitative box 24 .

[0025] The fixed plate 41 is fixed on the base plate 1 , and the fixed shell 51 is fixed on the sliding plate 44 ; the sliding plate 44 moves left and right, which drives the fixed shell 51 to move left and right.

[0026] The arc block 56 is slidably connected to the fixed shell 51 , and the trigger switch 55 is located on one side of the trigger disk 53 ; when the trigger disk 53 moves to the left, the trigger disk 53 contacts the trigger switch 55 , thereby turning on the trigger switch 55 .

[0027] The working principle of the present invention is as follows:

[0028] S1: By slowly adding raw materials into the quantitative box 24, more and more raw materials in the quantitative box 24 will cause the quantitative box 24 to move downward, and the downward movement of the quantitative box 24 will drive the support plate 33 to move downward, and the downward movement of the support plate 33 will drive the sliding rod 32 to move downward, and the downward movement of the sliding rod 32 will drive the sliding plate 34 to move downward, and the downward movement of the sliding plate 34 will squeeze the arc block 56;

[0029] S2: The arc block 56 is squeezed to move to the left, and the arc block 56 moves to the left to drive the transmission rod 52 to move to the left, and the transmission rod 52 moves to the left to drive the trigger plate 53 to move to the left, and the trigger plate 53 moves to the left to make the trigger plate 53 contact with the trigger switch 55, so that the trigger plate 53 controls the motor 22 to start;

[0030] S3: The rotation of the motor 22 drives the winding wheel 23 to rotate, and the rotation of the winding wheel 23 causes the pulling rope 25 to be wound around the winding wheel 23, and the pulling rope 25 is wound around the winding wheel 23, which causes the bottom end of the pulling rope 25 to move upward, and the upward movement of the bottom end of the pulling rope 25 drives the quantitative box 24 to move upward, so that when the material guide pipe 7 on the quantitative box 24 moves to the top of the extruder body 6, the control switch opens the material guide pipe 7, so that the raw materials are transported to the inside of the quantitative box 24;

[0031] S4: And when it is necessary to deliver different amounts to the inside of the extruder body 6, turn the handle 45. The rotation of the handle 45 will drive the threaded rod 42 to rotate, and the rotation of the threaded rod 42 will cause the threaded rod 42 to move left and right. The left and right movement of the threaded rod 42 will drive the push plate 43 to move left and right. The left and right movement of the push plate 43 will drive the sliding plate 44 to move left and right. The left and right movement of the sliding plate 44 will drive the fixed shell 51 to move left and right. The left and right movement of the fixed shell 51 will drive the arc block 56 to move left and right. The left and right movement of the arc block 56 will increase or decrease the contact time between the sliding plate 34 and the arc block 56 of the same weight of raw materials, so that the position of the arc block 56 can be adjusted as needed.

[0032] The present invention uses the weight of the raw materials in the quantitative box 24 to move the sliding plate 34 downward, so that the sliding plate 34 squeezes the arc block 56, causing the arc block 56 to move to the left. The movement of the arc block 56 to the left causes the trigger switch 55 to control the motor 22 to start, thereby transporting the raw materials in the quantitative box 24 to the inside of the extruder body 6, and the handle 45 can also be rotated to control the contact time between the sliding plate 34 and the arc block 56, so that the raw materials injected into the quantitative box 24 can be quantified.
