Description

Technical Field

[0001] The utility model relates to the technical field of twin-screw extruders, in particular to a micro twin-screw extruder. Background Art

[0002] The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding processing of extruded products.

[0003] At present, when the extruder is in use, a shell is installed to cover the internal structure. On the one hand, it improves the safety of the device, and on the other hand, it increases the aesthetics of the device. However, the method of installing the shell is generally to fix it with multiple bolts, which results in the need to unscrew the bolts one by one during installation and disassembly, which is time-consuming and laborious.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A micro twin-screw extruder comprises a support frame and a shell, wherein a servo motor is arranged on the top of the support frame, and a screw is transmission-connected to the output end of the servo motor, a groove is provided on one end of the support frame close to the servo motor, a card slot is connected in the groove, and a through hole penetrating the support frame is connected in the card slot, the shell is located on the top of the support frame and covers the servo motor and the screw, a fixed cylinder is fixed on one end of the shell close to the servo motor, a telescopic rod is slidably arranged in the fixed cylinder, a card block matched with the card slot is fixed on the end of the fixed cylinder, and a reset spring wound on the telescopic rod is arranged between the fixed cylinder and the card block.

[0007] Preferably, the top of the groove is connected to a limiting groove with an opening, and the limiting groove is slidably connected to the fixing cylinder.

[0008] Preferably, a hopper is provided on the top of the shell, the shell extends out of one end of the support frame away from the servo motor, and the bottom of the shell is offset from the support frame to form a discharge port.

[0009] Preferably, the length of the support frame is set to 50-70 cm, and the length of the shell is set to 60-80 cm.

[0010] Preferably, when the return spring contracts, the fixed tube, the telescopic rod and the clamping block are located in the groove, and the return spring is reset in the groove to push the clamping block into the slot.

[0011] Preferably, the support frame and the outer shell are both configured as shells made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model inserts the fixing tube into the groove by pressing the card block, inserts the card block into the card slot by the resilience of the reset spring, thereby completing the connection between the shell and the support frame, and presses the card block through the through hole to make the card block disengage from the card slot to complete the disassembly between the shell and the support frame, which is simple, efficient, time-saving and labor-saving;

[0014] 2. The utility model inserts the fixing tube into the limiting groove while inserting the fixing tube into the groove. The limiting groove plays a guiding role on the one hand, and ensures the stability of the position of the fixing tube in the groove on the other hand, thereby avoiding the instability of the housing caused by the displacement of the fixing tube in the groove.

[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] like Figure 1As shown, the micro twin-screw extruder of the utility model includes a support frame 1, and two servo motors 3 are symmetrically fixed on the left side of the top of the support frame 1, and the output ends of the servo motors 3 are transmission-connected with screws 4, and the servo motors 3 drive the screws 4 to work, so as to convey and extrude the raw materials. A shell 2 is arranged on the top of the support frame 1 to cover the servo motor 3 and the screw 4. The shell 2 improves the safety of the extrusion work and the aesthetics of the device. The support frame 1 and the shell 2 are both arranged to be supported by stainless steel. On the one hand, the aesthetics of the device can be further improved by stainless steel, and on the other hand, the stability of the device can be improved by the rust-proof and corrosion-resistant properties of stainless steel, thereby extending the service life of the device.

[0024] like Figure 4 As shown, a hopper 9 is provided on the top of the housing 2, the length of the support frame 1 is set to 60 cm, the length of the housing 2 is set to 70 cm, and as shown in FIG. Figure 2 As shown, the shell 2 extends out of one end of the support frame 1 away from the servo motor 3, and the bottom of the shell 2 is offset from the support frame 1 to form a discharge port. The raw materials are input through the hopper 9, and the extruded products are output through the discharge port. At the same time, the discharge port formed by the offset between the bottom of the shell 2 and the support frame 1 forms a corner to prevent the extruded products from being directly output and splashing too far to be difficult to collect. The volume is reduced by a shorter length, thereby reducing space occupancy and facilitating movement, so that it can be applied to more scenarios and increase the scope of application.

[0025] like Figure 3 As shown, a groove 5 is provided at one end of the support frame 1 close to the servo motor 3, a card slot 6 is provided in the groove 5, and a through hole 7 penetrating the support frame 1 is provided in the card slot 6. Figure 4 As shown, a fixed cylinder 10 is fixed to one end of the shell 2 close to the servo motor 3, and a telescopic rod 11 is slidably arranged in the fixed cylinder 10, and a block 13 adapted to the slot 6 is fixed to the end of the fixed cylinder 10, and a reset spring 12 wound on the telescopic rod 11 is arranged between the fixed cylinder 10 and the block 13, and the reset spring 12 is contracted by pressing the block 13 so that the fixed cylinder 10, the telescopic rod 11 and the block 13 are inserted into the groove 5, and the block 13 is located in the groove 5 and is inserted into the block 13 by the resilience of the reset spring 12, thereby completing the connection between the shell 2 and the support frame 1, and pressing the block 13 through the through hole 7 makes the block 13 disengage from the slot 6, thereby completing the disassembly between the shell 2 and the support frame 1, which is simple and efficient, saving time and effort.

[0026] like Figure 3As shown, an open limiting groove 8 is provided at the top of the groove 5, and the limiting groove 8 is slidably connected to the fixing tube 10. By inserting the fixing tube 10 into the groove 5 and the fixing tube 10 into the limiting groove 8 at the same time, the limiting groove 8 can guide the fixing tube 10 on the one hand, and on the other hand, the limiting groove 8 can ensure the stability of the position of the fixing tube 10 in the groove 5, thereby avoiding the displacement of the fixing tube 10 in the groove 5 and causing the instability of the position of the shell 2, thereby ensuring the stability of the connection between the shell 2 and the support frame 1.

[0027] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
