Description

Technical Field

[0001] This utility model relates to the field of hemostatic machine technology, and in particular to a transmission mechanism for a hemostatic machine. Background Technology

[0002] Soft linen: A type of plant whose outer bark can be combed to make it a textile material. It is soft and easy to knead. Mechanical linen softening machines rely on pressure-pressurized grooved rollers to repeatedly bend and knead the fibers, making them soft and removing some impurities, thus facilitating the production and processing of linen.

[0003] However, the existing transmission mechanism of the hemp fiber machine has some shortcomings in use. Different stations of the hemp fiber machine (such as the feeding roller, combing roller, and stretching roller) require different speeds. However, the traditional transmission mechanism of the hemp fiber machine relies on fixed gears and transmission wheels to achieve power transmission. Once the speed ratio is assembled, it remains fixed. If it is necessary to adjust the speed ratio of different stations, the operator must stop the machine, disassemble the original gears or transmission wheels, and replace them with suitable new parts. The process is time-consuming and laborious, reduces the operating efficiency of the equipment, and cannot meet the usage requirements. Therefore, a transmission mechanism for the hemp fiber machine is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a transmission mechanism for a soft hemorrhoid machine to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transmission mechanism for a numbing machine includes a mounting plate. A numbing machine feeding roller is provided on the top of the mounting plate. A rotating gear is provided on the front side of the numbing machine feeding roller. A protective mounting assembly extending to the outside of the rotating gear is provided on the bottom of the mounting plate. A transmission engagement mechanism penetrating to the outside and meshing with the rotating gear is provided inside the protective mounting assembly. An adjustment assembly penetrating to the rear side is provided inside the protective mounting assembly.

[0007] The protective mounting assembly includes a transmission box, which is fixedly mounted on the bottom of the mounting plate. Two support frames are fixedly mounted on the bottom of the transmission box. A protective cover that fits over the rotating gear is fixedly mounted on the front side of the transmission box. Several mounting holes are provided inside the support frames.

[0008] Preferably, the transmission engagement mechanism includes two rotating shafts rotatably mounted on the inner wall of the transmission box and extending to its outer side. A conical transmission cylinder is fixedly mounted on the outer side of the rotating shaft. A drive motor is fixedly mounted on the rear side of the transmission box. The output shaft of the drive motor is fixedly connected to the rotating shaft on the right side. A transmission belt is installed between the outer sides of the two conical transmission cylinders. The rotating shaft on the left side extends into the interior of the protective cover and is fixedly connected to a control gear. A transmission gear that meshes with the rotating gear and the control gear is rotatably mounted on the front side of the transmission box.

[0009] Preferably, the adjusting assembly includes a lead screw, which is rotatably mounted inside the transmission box and extends to its rear side. A threaded block that fits against the bottom wall of the transmission box is threaded onto the outer side of the lead screw. An adjusting handwheel is fixedly mounted on the rear side of the lead screw, and a push block that is sleeved on the outside of the transmission belt is fixedly mounted on the top of the threaded block.

[0010] Preferably, a plurality of strip-shaped protrusions are fixedly installed on the outer side of the conical transmission cylinder, and the plurality of strip-shaped protrusions are distributed in a ring at equal intervals on the outer side of the conical transmission cylinder.

[0011] Preferably, the inner bottom wall of the transmission box is provided with a strip groove that matches the moving trajectory of the threaded block.

[0012] Preferably, a guide sleeve fitted onto the outside of the transmission belt is fixedly installed inside the push block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The transmission mechanism of this hemp softening machine, through the cooperation of the lead screw, threaded block and push block in the adjustment component, allows the operator to change the transmission contact position of the transmission belt by simply turning the adjustment handwheel without stopping the machine to disassemble the transmission structure. This enables rapid adjustment of the speed of the feeding roller of the hemp softening machine, solving the problem of low efficiency and the need to stop the machine for speed adjustment caused by the fixed gear ratio of traditional transmission mechanisms. It significantly improves the adaptability of the workstations in the hemp softening machine to different fiber processing processes.

[0015] The transmission mechanism of this hemp fiber machine features a protective cover mounted on the outside of the rotating gears within the protective mounting assembly. This effectively prevents fiber debris and dust from entering the meshing area between the rotating and transmission gears, reducing wear on the gear teeth. The support frame at the bottom of the transmission box has mounting holes for stable bolt connection to the equipment. The strip-shaped protrusions on the outside of the tapered transmission cylinder increase friction with the transmission belt, preventing slippage. The strip-shaped grooves on the bottom wall of the transmission box provide guiding constraints for the threaded blocks, preventing them from shifting during movement. This multi-layered protective design effectively reduces maintenance frequency and extends the equipment's service life. Attached Figure Description

[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model provides a technical solution: a transmission mechanism for a hemp fiber machine, including a mounting plate 1, a hemp fiber machine feeding roller 2 rotatably mounted on the top of the mounting plate 1, a rotating gear 3 fixedly connected to the front side of the hemp fiber machine feeding roller 2, the mounting plate 1 serving as the mounting base platform for the hemp fiber machine feeding roller 2, and the hemp fiber machine feeding roller 2 responsible for feeding the fiber to be processed into the hemp fiber machine station.

[0028] A protective mounting assembly 4 extending to the outside of the rotating gear 3 is fixedly installed on the bottom of the mounting plate 1. The protective mounting assembly 4 includes a transmission box 41, which is fixedly installed on the bottom of the mounting plate 1 as a housing for the transmission mechanism. Two support frames 42 are fixedly installed on the bottom of the transmission box 41. A protective cover 43 that fits on the outside of the rotating gear 3 is fixedly installed on the front side of the transmission box 41. Several mounting holes 44 are opened inside the support frame 42 to facilitate a stable connection with the equipment by bolts.

[0029] The protective mounting assembly 4 has a transmission engagement mechanism 5 that extends through to its outer side and meshes with the rotating gear 3. The transmission engagement mechanism 5 includes two rotating shafts 51, which are rotatably mounted on the inner wall of the transmission box 41 and extend to its outer side. A conical transmission cylinder 52 is fixedly mounted on the outer side of the rotating shaft 51. Several strip-shaped protrusions 521 are fixedly mounted on the outer side of the conical transmission cylinder 52. The strip-shaped protrusions 521 are evenly distributed in a ring on the outer side of the conical transmission cylinder 52. A drive motor 53 is fixedly mounted on the rear side of the transmission box 41. The output shaft of the drive motor 53 is fixedly connected to the rotating shaft 51 on the right side. A transmission belt 54 is installed between the outer sides of the two conical transmission cylinders 52. The conical surface design allows the transmission belt 54 to slide along the conical surface during adjustment, changing the contact radius with the conical transmission cylinder 52. The elastic material of the transmission belt 54 can buffer the impact load when the motor starts. The strip-shaped protrusions 521 on the outer side of the conical transmission cylinder 52 increase the friction with the transmission belt 54 and prevent slippage.

[0030] The left rotating shaft 51 extends into the interior of the protective cover 43 and is fixedly connected to the control gear 55. The front side of the transmission box 41 is rotatably mounted with a transmission gear 56 that meshes with the rotating gear 3 and the control gear 55. The transmission mechanism of the soft hemp machine can effectively prevent fiber debris and dust from entering the meshing area between the rotating gear 3 and the transmission gear 56 by setting the protective cover 43 in the protective mounting assembly 4 to fit outside the rotating gear 3, thereby reducing the wear of impurities on the gear tooth surface.

[0031] An adjustment assembly 6 is movably installed inside the protective mounting assembly 4, extending to its rear side. The adjustment assembly 6 includes a lead screw 61, which is rotatably installed inside the transmission box 41 and extends to its rear side. A threaded block 62 that fits against the inner bottom wall of the transmission box 41 is threaded on the outer side of the lead screw 61. A slotted groove 621 that matches the movement trajectory of the threaded block 62 is opened on the inner bottom wall of the transmission box 41. An adjustment handwheel 63 is fixedly installed on the rear side of the lead screw 61, allowing the operator to adjust the speed without tools, thus reducing the difficulty of operation.

[0032] A push block 64, which is fitted onto the outside of the transmission belt 54, is fixedly installed on the top of the threaded block 62. A guide sleeve 641, which is fitted onto the outside of the transmission belt 54, is fixedly installed inside the push block 64. The guide sleeve 641, made of flexible or smooth material, protects the outside of the transmission belt 54 from being scratched by the push block 64, thus extending the service life of the transmission belt 54. The strip groove 621 on the bottom wall of the transmission box 41 provides a guiding constraint for the threaded block 62, preventing it from deviating during movement. The transmission mechanism of this hemp machine, through the cooperation of the lead screw 61, threaded block 62 and push block 64 in the adjustment component 6, allows the operator to change the transmission contact position of the transmission belt 54 by simply rotating the adjustment handwheel 63 without stopping the machine to disassemble the transmission structure. This enables rapid adjustment of the speed of the feeding roller 2 of the hemp machine, solving the problem of low efficiency and the need to stop the machine for speed adjustment caused by the fixed gear ratio in traditional transmission mechanisms. It significantly improves the adaptability of the workstations in the hemp machine to different fiber processing processes. The overall structure, through multiple protective designs, effectively reduces the maintenance frequency and extends the service life of the equipment.

[0033] The working process of this utility model:

[0034] Step 1: During power transmission, the drive motor 53 starts, and its output shaft directly drives the right rotating shaft 51 to rotate. The conical transmission cylinder 52 on the outside of the right rotating shaft 51 rotates accordingly, and drives the left rotating shaft 51 to rotate synchronously through the transmission belt 54. The control gear 55 extending from the left rotating shaft 51 into the protective cover 43 meshes with the transmission gear 56. The transmission gear 56 further meshes with the rotating gear 3 on the front side of the soft hemp machine feed roller 2, and finally transmits the power of the drive motor 53 to the rotating gear 3 and the soft hemp machine feed roller 2 in sequence, so as to realize the stable rotation of the soft hemp machine feed roller 2.

[0035] Step two, during speed adjustment, the operator rotates the adjusting handwheel 63 to drive the lead screw 61 to rotate. The threaded block 62 on the outside of the lead screw 61, being threadedly connected to the lead screw 61, moves linearly along the strip groove 621 on the bottom wall of the transmission box 41. The pushing block 64 on top of the threaded block 62 moves along with it, and the guide sleeve 641 inside it is fitted onto the outside of the transmission belt 54. By pushing the transmission belt 54, the contact position between it and the two conical transmission cylinders 52 is changed (i.e., the effective transmission radius of the transmission belt 54 is changed), thereby adjusting the speed difference of the left and right rotating shafts 51, and finally achieving stepless adjustment of the speed of the feeding roller 2 of the hemp machine.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
