Description

Technical Field

[0001] This utility model belongs to the field of extruders, and more specifically, relates to an extruder that is easy to clean. Background Technology

[0002] Extruders are a type of plastic machinery. Based on the angle between the material flow direction at the die head and the screw centerline, extruder heads can be divided into right-angle die heads and angled die heads, etc.

[0003] Chinese patent CN214239472U discloses an extruder that is easy to clean. After prolonged use, the bolts on the outside of the first and second flanges can be removed, and the two flange covers can be opened by rotating the first and second connecting blocks. The first extrusion nozzle can then be flipped upwards to begin cleaning the inside.

[0004] However, in the aforementioned easy-to-clean extruder, the first extrusion nozzle is fixed by multiple bolts, and these bolts can only be removed one by one in sequence, which increases the disassembly time of the first extrusion nozzle and the workload of the workers.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an extruder that is easy to clean.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] An easy-to-clean extruder includes:

[0009] An extruder body, wherein a mounting base is connected to one side of the extruder body, and a first extrusion nozzle is provided on one side of the mounting base;

[0010] The positioning mechanism includes a plurality of first gears rotatably engaged on one side of the extruder body, a threaded rod at one end of the first gear, a toothed ring rotatably engaged on one side of the extruder body, and a drive mechanism located on one side of the extruder body for driving the toothed ring to rotate. The threaded rod passes through the mounting base and is threadedly engaged with the first extrusion nozzle.

[0011] Optionally, one end of the mounting base is provided with a first flange, one end of the first flange is provided with a through hole corresponding to the threaded rod, one end of the first extrusion nozzle is provided with a second flange, one end of the second flange is provided with a threaded hole corresponding to the threaded rod.

[0012] Optionally, the inner wall of the toothed ring has a plurality of first tooth grooves arranged in a circumferential array, and the toothed ring meshes with the first gear through the plurality of first tooth grooves.

[0013] Optionally, the drive mechanism includes a second gear rotatably engaged on one side of the extruder body and a throttle handle located at one end of the second gear. The outer circumference of the gear ring has a plurality of second tooth grooves, and the gear ring meshes with the second gear through the plurality of second tooth grooves.

[0014] Optionally, one end of the second gear is threaded with a Torx handle screw, and a positioning groove corresponding to the Torx handle screw is provided on one side of the extruder body.

[0015] Optionally, a second extrusion nozzle is threaded onto one end of the first extrusion nozzle.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] When the first extrusion nozzle needs to be disassembled for cleaning, the drive mechanism drives multiple first gears to rotate synchronously through the gear ring, which in turn drives multiple threaded rods to rotate synchronously. The threaded rods are threadedly engaged with the first extrusion nozzle, causing the first extrusion nozzle to slide until it disengages from the threaded rod. This facilitates quick disassembly of the first extrusion nozzle, improves the disassembly efficiency of the first extrusion nozzle, and reduces the workload of workers.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-3 As shown, this embodiment provides an extruder that is easy to clean, comprising:

[0029] Extruder body 1, with a mounting base 101 connected to one side of the extruder body 1, and a first extrusion nozzle 102 provided on one side of the mounting base 101;

[0030] The positioning mechanism 2 includes a plurality of first gears 201 rotatably engaged on one side of the extruder body 1, a threaded rod 202 at one end of the first gear 201, a toothed ring 203 rotatably engaged on one side of the extruder body 1, and a drive mechanism 204 at one side of the extruder body 1 for driving the toothed ring 203 to rotate. The threaded rod 202 passes through the mounting base 101 and is threadedly engaged with the first extrusion nozzle 102.

[0031] When the first extrusion nozzle 102 needs to be disassembled for cleaning, the drive mechanism 204 drives multiple first gears 201 to rotate synchronously through the gear ring 203, which in turn drives multiple threaded rods 202 to rotate synchronously. The threaded rods 202 are threadedly engaged with the first extrusion nozzle 102, causing the first extrusion nozzle 102 to slide until the first extrusion nozzle 102 disengages from the threaded rods 202. This facilitates quick disassembly of the first extrusion nozzle 102, improves the disassembly efficiency of the first extrusion nozzle 102, and reduces the workload of workers.

[0032] Please see Figure 2 As shown, in this embodiment, the mounting base 101 is provided with a first flange 103 at one end, and a through hole 104 corresponding to the threaded rod 202 at one end of the first flange 103. The first extrusion nozzle 102 is provided with a second flange 105 at one end, and a threaded hole 106 corresponding to the threaded rod 202 at one end of the second flange 105, so that the threaded rod 202 can pass through the through hole 104 and be threadedly engaged with the threaded hole 106 on the second flange 105. The inner wall of the gear ring 203 has a plurality of first tooth grooves arranged in a circumferential array. The gear ring 203 meshes with the first gear 201 through the plurality of first tooth grooves, so that the gear ring 203 meshes with the first gear 201 and drives the plurality of first gears 201 to rotate.

[0033] Please see Figure 2-3 As shown, the drive mechanism 204 in this embodiment includes a second gear 2041 rotatably engaged on one side of the extruder body 1, a throttle 2042 disposed at one end of the second gear 2041, and a toothed ring 203 having a plurality of second tooth grooves arranged on its outer circumference. The toothed ring 203 meshes with the second gear 2041 through the plurality of second tooth grooves, so that the second gear 2041 can be driven to rotate by the throttle 2042. The second gear 2041 drives a plurality of first gears 201 to rotate synchronously through the toothed ring 203, thereby driving a plurality of threaded rods 202 to rotate synchronously.

[0034] To reduce the probability of thread unwinding due to the rotation of the threaded rod 202, please refer to [link / reference needed]. Figure 2 As shown, in this embodiment, one end of the second gear 2041 is threaded with a Torx handle screw 2043. The extruder body 1 has a positioning groove 2044 corresponding to the Torx handle screw 2043 on one side, which facilitates the Torx handle screw 2043 to be screwed into the positioning groove 2044 to position the second gear 2041 after rotation, thereby reducing the probability of thread stripping caused by the extrusion pressure on the first extrusion nozzle 102.

[0035] Please see Figure 1-2 As shown, in this embodiment, the first extrusion nozzle 102 is threaded to one end with a second extrusion nozzle 107, which facilitates the installation and removal of the second extrusion nozzle 107.

[0036] Working principle: When the first extrusion nozzle 102 needs to be disassembled for cleaning, turn the Torx handle screw 2043 to unscrew the positioning groove 2044, and then drive the second gear 2041 to rotate through the throttle 2042. The second gear 2041 drives multiple first gears 201 to rotate synchronously through the gear ring 203, which in turn drives multiple threaded rods 202 to rotate synchronously. The threaded rods 202 are threadedly engaged with the second flange 105, causing the second flange 105 to slide until the second flange 105 disengages from the threaded rods 202, which facilitates quick disassembly of the first extrusion nozzle 102, improves the disassembly efficiency of the first extrusion nozzle 102, and reduces the labor intensity of workers.
