Abstract
Description
Technical Field
[0001] This utility model relates to the field of extruder technology, specifically to an extruder with an extrusion thickness adjustment mechanism. Background Technology
[0002] An extruder is a shaping device that processes specific materials into strips. Different molds can be installed at the discharge port. After the material is squeezed, it will pass through the mold opening and form a specific shape. In order to ensure the smooth extrusion of the material, it is necessary to preheat the material to prevent it from solidifying before feeding it into the extrusion mechanism.
[0003] Most extruder troughs have fixed specifications. If the basic thickness needs to be adjusted, the mold needs to be replaced temporarily. Disassembly and reassembly are time-consuming, and impurities are easily mixed into the material, affecting the extrusion efficiency. Furthermore, a stopped machine can easily cause the material to solidify, and the thickness cannot be changed continuously.
[0004] Now, a novel extruder with an extrusion thickness adjustment mechanism is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an extruder with an extrusion thickness adjustment mechanism to solve the problem of inconvenient extrusion thickness adjustment mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an extruder with an extrusion thickness adjustment mechanism, comprising a horizontal frame and a housing, wherein the housing is welded to the upper right corner of the outer side of the horizontal frame, and a vertical plate is movably inserted into the housing, and a pressure plate is welded to the lower right corner of the vertical plate, a lead screw is movably connected to the center of the top of the pressure plate, a transmission gear is movably connected to the right side of the top of the horizontal frame, and a threaded cylinder is welded to the top of the transmission gear, a second motor is installed in the upper right corner of the inner side of the horizontal frame, and a main guide gear is fixed to the top of the output end of the second motor, a slot is provided between the upper and lower parts of the inner side of the pressure plate, and a groove is provided inside the right side of the horizontal frame.
[0007] As a further technical solution of this utility model, the slot is engaged with the outside of the groove on the right side of the horizontal frame, and the pressure plate can be vertically raised and lowered inside the groove.
[0008] As a further technical solution of this utility model, the vertical plate can move vertically along the inside of the housing, and the top of the lead screw is embedded in the threaded cylinder.
[0009] As a further technical solution of this utility model, a bevel gear one is movably connected to the left side of the outer side of the horizontal frame, a fixing plate is installed at the upper left corner of the outer side of the horizontal frame, and a motor one is installed at the top of the fixing plate. A bevel gear two is movably connected below the fixing plate. A screw is horizontally assembled in the bevel gear one, and a push plate is installed on the right side of the screw. A crossbar is horizontally fixed below the left side of the screw, and a slider is fixed to the right side of the top of the crossbar. A slide rail is horizontally provided below the outer side of the horizontal frame.
[0010] As a further technical solution of this utility model, the bottom of the output end of the first motor is fixedly connected to the second bevel gear, the second bevel gear is meshed with the upper left corner of the first bevel gear, and the inner side of the first bevel gear is provided with the inner wall of the matching screw.
[0011] As a further technical solution of this utility model, the push plate can move left and right along the inside of the horizontal frame, and the screw and the horizontal bar are on the same vertical plane.
[0012] As a further technical solution of this utility model, a box is installed on the upper left corner of the outer side of the horizontal frame, and a valve is fixed on the left side of the top of the outer side of the box. A heating box is installed on the top of the valve. A motor is installed at the center of the top of the outer side of the box. A blade is movably connected between the upper and lower parts of the center inside the box. A bottom groove is welded to the lower left corner of the inside of the box, and a through groove is provided between the bottom groove and the horizontal frame.
[0013] As a further technical solution of this utility model, the blade can rotate horizontally in the box body, and the blade is embedded between the valve and the through groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the extruder with extrusion thickness adjustment mechanism not only realizes the adjustment of extrusion thickness and the cleaning of material inside the cross frame, but also realizes the control of material entering and exiting the cross frame;
[0015] (1) By inserting a vertical plate inside the housing, start the second motor and rotate the main gear plate outside the horizontal frame, thereby pushing the transmission gear plate and threaded cylinder on the left side. Since the vertical plate on the left side is embedded in the housing, the screw inside the threaded cylinder will drive the pressure plate to sink vertically when it rotates. The material pushed from the left side of the horizontal frame to the right side will automatically adjust its thickness after contacting the pressure plate and will be extruded and formed after passing through the trough.
[0016] (2) By installing a push plate on the right side of the screw, when the material inside the heating box passes through the box and falls into the horizontal frame, the motor is turned on and the bevel gear 2 rotates at the bottom of the fixed plate, forcing it to push the bevel gear 1 in the lower right corner. Under the restriction of the slider in the slide, the screw fixed to the horizontal bar can be moved horizontally, and then the push plate is guided to scrape the material along the inside of the horizontal frame, so as to avoid the material sticking to the inner wall of the horizontal frame and making it inconvenient to clean later.
[0017] (3) The material inside the heating box will continuously pass through the box and enter the horizontal frame after the valve is opened. The bottom of the valve is located above the bottom groove. There is a gap between the two for the blade to rotate horizontally, which can cut the material and prevent the material from leaving the heating box in conjunction with the valve. This facilitates the feeding mechanism to the right and prevents the sticky material above from affecting the operation of the push plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4An embodiment of this utility model is provided: an extruder with an extrusion thickness adjustment mechanism, including a horizontal frame 1 and a housing 2. The housing 2 is welded to the upper right corner of the outer side of the horizontal frame 1, and a vertical plate 3 is movably inserted into the housing 2. A pressure plate 6 is welded to the lower right corner of the vertical plate 3. A lead screw 27 is movably connected to the center of the top of the pressure plate 6. A transmission gear 20 is movably connected to the right side of the top of the horizontal frame 1, and a threaded cylinder 4 is welded to the top of the transmission gear 20. A second motor 18 is installed in the upper right corner of the inner side of the horizontal frame 1, and a main guide gear 19 is fixed to the top of the output end of the second motor 18. A slot 21 is provided between the upper and lower parts of the inner side of the pressure plate 6, and a groove 5 is provided inside the right side of the horizontal frame 1.
[0025] The slot 21 is engaged with the outside of the groove 5 on the right side of the horizontal frame 1. The pressure plate 6 can be vertically raised and lowered inside the groove 5. The vertical plate 3 can move vertically along the inside of the housing 2. The top of the screw 27 is embedded in the threaded cylinder 4.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the motor 18 is started, and the main gear 19 rotates outside the horizontal frame 1, thereby pushing the transmission gear 20 and the threaded cylinder 4 on the left side. Since the vertical plate 3 on the left side is embedded in the housing 2, the screw 27 inside the threaded cylinder 4 will drive the pressure plate 6 to sink vertically when it rotates. The material pushed from the left side of the horizontal frame 1 to the right side will automatically adjust its thickness after contacting the pressure plate 6.
[0027] A bevel gear 10 is movably connected to the left side of the outside of the horizontal frame 1. A fixing plate 17 is installed at the upper left corner of the outside of the horizontal frame 1, and a motor 16 is installed at the top of the fixing plate 17. A bevel gear 15 is movably connected below the fixing plate 17. A screw 11 is horizontally assembled in the bevel gear 10, and a push plate 12 is installed on the right side of the screw 11. A horizontal bar 9 is horizontally fixed below the left side of the screw 11. A slider 8 is fixed to the right side of the top of the horizontal bar 9. A slide rail 7 is horizontally provided below the outside of the horizontal frame 1.
[0028] The bottom of the output end of motor 16 is fixedly connected to bevel gear 2 15. Bevel gear 2 15 is meshed with the upper left corner of bevel gear 10. The inner side of bevel gear 10 is provided with the inner wall of matching screw 11. Push plate 12 can move left and right along the inside of the horizontal frame 1. Screw 11 and horizontal bar 9 are on the same vertical plane.
[0029] Specifically, such as Figure 1 As shown, when the material inside the heating box 13 passes through the box 14 and falls into the horizontal frame 1, the motor 16 is turned on and the bevel gear 15 rotates at the bottom of the fixed plate 17, forcing it to push the bevel gear 10 in the lower right corner. Under the restriction of the slider 8 in the slide 7, the screw 11 fixed to the crossbar 9 can move horizontally, thereby guiding the push plate 12 to scrape the material along the inside of the horizontal frame 1 and push it out.
[0030] A box 14 is installed on the upper left corner of the outer side of the horizontal frame 1, and a valve 22 is fixed on the left side of the top of the outer side of the box 14. A heating box 13 is installed on the top of the valve 22. A motor 23 is installed at the center of the top of the outer side of the box 14. A blade 24 is movably connected between the upper and lower parts of the center inside the box 14. A bottom groove 25 is welded to the lower left corner inside the box 14, and a through groove 26 is provided between the bottom groove 25 and the horizontal frame 1. The blade 24 can rotate horizontally in the box 14. The blade 24 is embedded between the valve 22 and the through groove 26.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the material inside the heating box 13 will continuously pass through the box 14 and enter the horizontal frame 1 after the valve 22 is opened. The bottom of the valve 22 is located above the bottom groove 25, and there is a gap between the two for the blade 24 to rotate laterally, which can cut the material and, together with the valve 22, prevent the material from leaving the heating box 13, making it convenient for the pushing mechanism to feed the material to the right.
[0032] Working principle: In use, the material inside the heating box 13 will continuously pass through the box body 14 and enter the horizontal frame 1 after the valve 22 is opened. The bottom of the valve 22 is located above the bottom groove 25, with a gap between them for the blade 24 to rotate laterally, which can cut the material and prevent the material from leaving the heating box 13. Then, the motor 16 is turned on and rotates the bevel gear 15 at the bottom of the fixed plate 17, forcing it to push the bevel gear 10 in the lower right corner. Under the restriction of the slider 8 in the slide 7, the material can be cut. The screw 11, which is fixed to the crossbar 9, is moved horizontally, and then the push plate 12 is guided to scrape the material along the inside of the cross frame 1 to avoid the material sticking to the inner wall of the cross frame 1 and making it inconvenient to clean later. The motor 18 is started in advance, and the main guide gear 19 is rotated outside the cross frame 1, thereby pushing the transmission gear 20 and the threaded cylinder 4 on the left side. Since the vertical plate 3 on the left side is embedded in the housing 2, when the threaded cylinder 4 rotates, the screw 27 inside will drive the pressure plate 6 to sink vertically. The material pushed from the left side of the cross frame 1 to the right side automatically adjusts its thickness and is extruded after contacting the pressure plate 6.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
