Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to a power transmission and drive device for a plastic powder extruder. Background Technique

[0002] The power transmission and drive device for a plastic powder extruder is mainly used to transmit the power of a driving motor to the extrusion screw of the extruder body, so that the extrusion screw can operate normally, thereby realizing the extrusion operation of plastic powder. During the production process of plastic powder, this device plays a key role in power transmission and controlling the operation of the extrusion screw, and directly affects the efficiency and quality of plastic powder extrusion.

[0003] In the prior art, it is often inconvenient to disassemble and replace the power transmission and drive device. For example, due to its structural design, when disassembling the motor or transmission components, complex tools and cumbersome operation steps are required. The connection between components may adopt a relatively fixed and difficult-to-dismantle connection method, which makes it take a lot of time and effort when it is necessary to replace damaged components (such as transmission gears, etc.) or perform maintenance and adjustment on the device. In order to improve it, a power transmission and drive device for a plastic powder extruder is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a power transmission and drive device for a plastic powder extruder is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A power transmission and drive device for a plastic powder extruder, comprising a support frame, an extruder body and a driving motor. An installation frame is installed on the driving motor. A plurality of installation grooves corresponding to the installation frame are provided on the support frame. An upper top groove is provided on the installation frame. A positioning block is provided in the upper top groove through an upper top mechanism. A positioning hole is provided on the support frame. Clamping shafts are provided on both the extrusion screw on the extruder body and the output shaft of the driving motor. A transmission gear and a driving gear are respectively provided on the two clamping shafts. Extrusion grooves are provided on both the two clamping shafts. A limiting block is provided in the extrusion groove through an extrusion mechanism.

[0007] Preferably, the upper top mechanism includes a vertical spring arranged in the upper top groove, and both ends of the vertical spring are elastically connected to the outer wall of the positioning block and the inner wall of the upper top groove respectively.

[0008] Preferably, the extrusion mechanism includes a horizontal spring installed in the extrusion groove, and both ends of the horizontal spring are elastically connected to the outer wall of the limiting block and the inner wall of the extrusion groove respectively.

[0009] Preferably, the vertical cross-sectional view of the clamping shaft is a regular hexagon, and the vertical cross-sectional views of the perforations corresponding to the clamping shaft on the transmission gear and the driving gear are also regular hexagons.

[0010] Preferably, retaining rings are provided on both the extrusion screw on the extruder body and the output shaft of the driving motor, and the distance between the retaining rings and the limiting blocks is equal to the thickness of the transmission gear and the driving gear.

[0011] Preferably, a plurality of the mounting grooves are equally spaced vertically, and the positioning holes penetrate from top to bottom into the lowermost mounting groove.

[0012] Preferably, the surfaces of the retaining rings and the limiting blocks in contact with the transmission gear and the driving gear are polished, and the number of limiting blocks on each clamping shaft is two.

[0013] Preferably, a handle is provided on the driving motor, and a rubber sleeve is sleeved on the handle.

[0014] Advantages of the utility model:

[0015] 1. Through the cooperation of the positioning block on the mounting frame, the vertical spring in the upper top groove, and the positioning holes and mounting grooves on the support frame, the stable installation of the mounting frame on the support frame is realized. The vertical spring can push the positioning block into the positioning hole, preventing the mounting frame from falling out of the mounting groove, ensuring the stability of the driving motor installed on the support frame, and providing a reliable basis for power transmission.

[0016] 2. The connection between the transmission gear and the clamping shaft, the design of the limiting blocks on the clamping shaft, the horizontal spring in the extrusion groove, and the retaining ring ensure the stable installation of the transmission gear and the driving gear on the clamping shaft. The horizontal spring extrudes the limiting block, preventing the transmission gear and the driving gear from falling off the clamping shaft, and the retaining ring restricts the axial movement of the transmission gear and the driving gear, thus ensuring the connection stability between the gear and the shaft during power transmission and preventing transmission failures.

[0017] 3. The structural design in which the vertical cross-sections of the clamping shaft, the transmission gear, and the driving gear are regular hexagons enables synchronous rotation operations between them. This structure ensures the effective transmission of power during the transmission process, improves the accuracy and efficiency of power transmission, helps the extrusion screw to operate stably at a predetermined speed and torque, and guarantees the quality of plastic powder extrusion.

[0018] 4. The regular hexagon structure and the design of the limiting blocks not only achieve synchronous rotation but also enable the convenient disassembly and assembly of the transmission gear and the driving gear. When it is necessary to replace transmission gears or driving gears of different sizes, the operation can be carried out conveniently, improving the flexibility and maintainability of the device.

[0019] 5. There are multiple mounting grooves evenly distributed at equal intervals up and down on the support frame. After the sizes of the transmission gear or the driving gear are changed, if it is necessary to appropriately increase or decrease the height of the driving motor, the mounting frame can be conveniently installed in the upper or lower mounting groove. This design makes the height adjustment of the driving motor simple and easy, can quickly adapt to different production requirements, and improves the adaptability of the entire device to different production requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Refer to Figures 1-6, A power transmission and drive device for a plastic powder extruder, including a support frame 1, an extruder body 2 and a drive motor 5. An installation frame 8 is installed on the drive motor 5. A plurality of installation grooves 9 corresponding to the installation frame 8 are provided on the support frame 1. An upper top groove 11 is provided on the installation frame 8. A positioning block 12 is provided in the upper top groove 11 through an upper top mechanism. A positioning hole 10 is provided on the support frame 1. Clamping shafts 3 are provided on both the extrusion screw on the extruder body 2 and the output shaft of the drive motor 5. A transmission gear 4 and a driving gear 7 are respectively provided on the two clamping shafts 3. Extrusion grooves 14 are provided on both the two clamping shafts 3. A limiting block 15 is provided in the extrusion groove 14 through an extrusion mechanism.

[0029] The upper top mechanism includes a vertical spring 13 provided in the upper top groove 11. The two ends of the vertical spring 13 are elastically connected to the outer wall of the positioning block 12 and the inner wall of the upper top groove 11 respectively. The vertical spring 13 realizes the upward top of the positioning block 12, and it can be extruded into the positioning hole 10 to prevent the installation frame 8 from falling off the installation groove 9.

[0030] The extrusion mechanism includes a horizontal spring 16 installed in the extrusion groove 14. The two ends of the horizontal spring 16 are elastically connected to the outer wall of the limiting block 15 and the inner wall of the extrusion groove 14 respectively. The horizontal spring 16 realizes the extrusion operation of the limiting block 15. After it is extruded, neither the transmission gear 4 nor the driving gear 7 can fall off the clamping shaft 3.

[0031] The vertical cross-sectional view of the clamping shaft 3 is in the shape of a regular hexagon. The vertical cross-sectional views of the through holes corresponding to the clamping shaft 3 on the transmission gear 4 and the driving gear 7 are also in the shape of a regular hexagon. The above regular hexagon structure enables the clamping shaft 3, the transmission gear 4 and the driving gear 7 to achieve synchronous rotation operation and convenient disassembly.

[0032] Circular snap rings are provided on both the extrusion screw on the extruder body 2 and the output shaft of the drive motor 5. The distance between the circular snap ring and the limiting block 15 is equal to the thickness of the transmission gear 4 and the driving gear 7. This design can ensure that the transmission gear 4 and the driving gear 7 cannot move axially after being installed on the clamping shaft 3.

[0033] The plurality of installation grooves 9 are equally spaced vertically. The positioning hole 10 penetrates from top to bottom into the lowermost installation groove 9. Therefore, no matter which installation groove 9 the installation frame 8 is installed in, the positioning block 12 can be pressed through the positioning hole 10 to be compressed into the upper top groove 11.

[0034] The surfaces of the circular snap ring and the limiting block 15 that contact the transmission gear 4 and the driving gear 7 are polished. The number of limiting blocks 15 on each clamping shaft 3 is two. The polishing treatment ensures smoothness and reduces contact damage. The two limiting blocks 15 are arranged at equal intervals circumferentially to ensure uniform force.

[0035] A handle 6 is provided on the drive motor 5, and a rubber sleeve is sleeved on the handle 6. The handle 6 facilitates the lifting and transporting operation of the drive motor 5, and the rubber sleeve has a protective effect to protect the hand.

[0036] When the utility model is in use, the drive motor 5 starts to drive the driving gear 7 to rotate. The rotation of the driving gear 7 can cooperate with the transmission gear 4 to drive the extrusion screw in the extruder body 2 to operate. When it is necessary to disassemble (replace) the power transmission and driving device, first, the rod-shaped component enters the positioning hole 10 from top to bottom, presses the positioning block 12 to compress the vertical spring 13 and enters the upper top groove 11. Then, the drive motor 5 is horizontally moved by means of the handle 6, so that components such as the drive motor 5, the mounting bracket 8 and the driving gear 7 are all disassembled. At this time, the limiting blocks 15 on the two clamping shafts 3 are pressed to compress the horizontal spring 16 and enter the extrusion groove 14. Then, the transmission gear 4 and the driving gear 7 are horizontally moved to complete the disassembly operation.

[0037] Since the transmission gear 4 and the driving gear 7 are convenient to disassemble and assemble, their replacement is simple and fast. Different sizes can be replaced immediately for matching to meet the extrusion production of the extruder body 2. When the size of the transmission gear 4 or the driving gear 7 is replaced, it may be necessary to appropriately increase or decrease the height of the drive motor 5. At this time, the mounting bracket 8 is installed in the upper or lower mounting groove 9.

[0038] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
