Description

Technical Field

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

[0002] Meat grinders are common meat processing equipment on the market. Traditional dual-purpose grinders use a motor, gears, and chains to operate the grinding and slicing mechanisms separately. Multiple gears of different sizes are needed to achieve speed reduction, and a corresponding clutch is required to switch between grinding and slicing functions. The overall structure is complex and inconvenient for disassembly and maintenance. Furthermore, because the motor is horizontally placed while its internal gears and bearings are longitudinally distributed, it is difficult to add lubricating oil for lubrication. Therefore, the equipment needs to be disassembled periodically to apply lubricating oil to various components to maintain normal operation. For example, Chinese patent document CN201410619106.X discloses a dual-purpose grinder. The gearbox in this application has several gears and bearings arranged sequentially to reduce the output shaft speed. The overall structure is very complex, and the gearbox is large, increasing the weight of the equipment and raising manufacturing costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a meat grinder transmission mechanism. It employs a worm gear and bevel gear to drive the meat grinder and slicing mechanisms with a single motor. The switching of the meat grinding function is achieved by rotating the motor in both directions and using a one-way bearing. This solves the problem of complex structure and inconvenient disassembly and maintenance of the transmission mechanism in existing meat grinders.

[0004] The specific technical solution is as follows:

[0005] A meat grinder transmission mechanism includes a transmission housing. A meat grinder shaft and a slicer shaft are horizontally inserted through both ends of one side of the transmission housing. A transmission assembly is housed inside the transmission housing, with both ends of the assembly connected to the meat grinder shaft and the slicer shaft, respectively. The transmission assembly is driven by a drive motor mounted at the bottom of the transmission housing. The transmission assembly includes a worm gear, a worm, a spindle, a first one-way bearing, a second one-way bearing, a driving bevel gear, and a driven bevel gear. The worm is longitudinally rotatably disposed on one side of the middle of the transmission housing, with its bottom end penetrating the bottom of the transmission housing and fixedly connected to the output shaft of the drive motor. One side of the worm meshes with the worm gear, which is mounted on the spindle. The spindle is horizontally rotatably disposed within the transmission housing, with both ends of the spindle connected to the inner rings of the first and second one-way bearings, respectively. The two rotating shafts are connected, with one-way bearings rotating in opposite directions. One-way bearings one and two are each housed in a rotating sleeve. At opposite ends of the two rotating sleeves, horizontal shafts concentric with the mandrel are provided. Each shaft is equipped with a driving bevel gear, and one driven bevel gear meshes with one side of each driving bevel gear. The two driven bevel gears are respectively mounted on the meat grinder shaft and the slicer shaft, so that when the shafts rotate, the driving and driven bevel gears engage to drive the meat grinder shaft and the slicer shaft to rotate respectively. When the drive motor rotates forward, it drives the mandrel, one-way bearing one, the rotating shaft, and the meat grinder shaft to rotate via a worm gear. When the drive motor rotates in reverse, it drives the mandrel, one-way bearing two, the rotating shaft, and the slicer shaft to rotate via a worm gear.

[0006] Furthermore, the transmission housing includes a base and a cover plate. The base has a rectangular housing structure, and the upper end of the base is open and the cover plate is installed thereon.

[0007] Furthermore, a bearing housing is integrally formed above the worm gear within the transmission housing, and a rotating bearing is fixedly mounted in the bearing housing. The inner ring of the rotating bearing is located at the upper shaft end of the worm gear.

[0008] Furthermore, the inner cavity of the transmission housing is integrally formed with positioning brackets at both ends, and the positioning brackets have a groove in the middle for the spindle to pass through; a bearing support is longitudinally arranged between the two positioning brackets and the two sides of the bearing bracket, and the two bearing supports are rotatably connected to the two ends of the spindle through bearings.

[0009] Furthermore, a protruding seat is provided on one side of the inner wall of the transmission housing cavity. The protruding seat is located on the side away from the worm gear. The bottom of the protruding seat extends to the bottom of the base, and the top of the protruding seat is flush with the top of the base. A screw hole for mounting the drive motor is longitudinally provided in the protruding seat. A mounting plate is horizontally provided on the bottom side of the transmission housing away from the protruding seat. Screw holes for longitudinally mounting the drive motor are also provided at the left and right ends of the mounting plate.

[0010] Furthermore, a rotating seat is provided on the inner wall of each end of the transmission housing, and the two rotating seats are rotatably connected to one end of two rotating shafts through bearings.

[0011] Furthermore, each of the rotating sleeves has a hollow cylindrical structure. One end of the rotating sleeve is open and the one-way bearing one or one-way bearing two is embedded therein. The outer rings of one-way bearing one and one-way bearing two are respectively fitted and fixedly connected to the inner walls of the two rotating sleeves. The other end of the rotating sleeve is closed, and the rotating shaft is integrally formed at the center of the other end of the rotating sleeve.

[0012] The beneficial effects of this utility model are reflected in:

[0013] (1) Compared with the traditional gear and chain transmission structure and the clutch to achieve power switching, this utility model uses a worm gear and bevel gear to realize the operation of the meat grinding mechanism and the slicing mechanism driven by a single motor. Then, the forward and reverse rotation of the motor is combined with a one-way bearing to drive the meat grinder shaft or the slicer shaft to rotate, thereby realizing the switching of the grinding and slicing function. The overall structure is simpler and more compact, and it is easy to install, disassemble and maintain.

[0014] (2) The transmission components inside the transmission housing adopt a horizontal distribution structure, so as to facilitate the addition of lubricating oil to the inside of the transmission housing, immerse the transmission components in the lubricating oil, keep the gears lubricated, improve the cooling effect, reduce equipment noise, and effectively improve the service life of the transmission components.

[0026] Please see the appendix Figure 1-7This embodiment provides a transmission mechanism for a meat grinder, including a transmission housing 1. A meat grinder shaft 4 and a slicer shaft 5 are horizontally connected to both ends of one side of the transmission housing 1. A transmission assembly 3 is located inside the transmission housing 1, with both ends connected to the meat grinder shaft 4 and the slicer shaft 5 respectively. The transmission assembly is driven by a drive motor 2 installed at the bottom of the transmission housing 1. The transmission assembly 3 includes a worm gear 31, a worm 32, a spindle 33, a first one-way bearing 34, a second one-way bearing 35, a driving bevel gear 38, and a driven bevel gear 39. The worm 32 is longitudinally rotatably disposed on one side of the middle of the transmission housing. The bottom end of the worm 32 penetrates the bottom of the transmission housing 1 and is fixedly connected to the output shaft of the drive motor 2. The worm gear 31 is meshed with one side of the worm 32 and is disposed on the spindle 33. The spindle 33 is horizontally rotatably disposed in the transmission housing. Both ends of the spindle 33 are connected to the inner rings of the first one-way bearing 34 and the second one-way bearing 35 respectively. One-way bearing 34 and one-way bearing 35 rotate in opposite directions. One-way bearing 34 and one-way bearing 35 are each housed in a rotating sleeve 36. At the far ends of both rotating sleeves 36, horizontally arranged shafts 37 are concentric with the spindle 33. Each shaft 37 is equipped with a driving bevel gear 38, and one side of each driving bevel gear 38 meshes with a driven bevel gear 39. The two driven bevel gears 39 are respectively mounted on the meat grinder shaft 4 and the slicer shaft 5, causing the rotation... When shaft 37 rotates, the active bevel gear 38 and the driven bevel gear 39 cooperate to drive the meat grinder shaft 4 and the slicer shaft 5 to rotate respectively. When the drive motor 2 rotates forward, the worm gear 31 and worm 32 cooperate to drive the spindle 33, one-way bearing 34, rotating shaft 37 and meat grinder shaft 4 to rotate. When the drive motor 2 rotates in reverse, the worm gear 31 and worm 32 cooperate to drive the spindle 33, one-way bearing 35, rotating shaft 37 and slicer shaft 5 to rotate, thereby realizing the switching of the grinding and slicing functions.

[0027] In this embodiment, each of the rotating sleeves 36 has a hollow cylindrical structure. One end of the rotating sleeve 36 is open and a one-way bearing 34 or a one-way bearing 35 is embedded therein. The outer rings of the one-way bearing 34 and the one-way bearing 35 are respectively fitted and fixedly connected to the inner walls of the two rotating sleeves 36. The other end of the rotating sleeve 36 is closed, and a rotating shaft 37 is integrally formed at the center of the other end of the rotating sleeve 36. When the spindle 33 rotates clockwise, the inner ring of the one-way bearing 34 and its outer ring remain relatively fixed, thereby driving the rotating shaft 37 in the direction of the one-way bearing 34 to rotate. Meanwhile, the inner ring of the one-way bearing 35 and its outer ring remain relatively rotating, so the rotating shaft 37 in the direction of the one-way bearing 35 remains stationary. When the spindle 33 reverses, the inner and outer rings of the one-way bearing 34 maintain relative rotation, the shaft 37 in the direction of the one-way bearing 34 remains stationary, while the inner and outer rings of the one-way bearing 35 remain fixed, thereby driving the shaft 37 in the direction of the one-way bearing 35 to rotate. Therefore, the drive motor 2 drives the spindle 33 to rotate forward or backward, thereby achieving the switching operation of the slitting function.

[0028] In this embodiment, the transmission housing 1 includes a base 101 and a cover plate 102. The base 101 has a rectangular shell structure, with an opening at the top where the cover plate 102 is installed. The cover plate 102 is connected and fixed to the base 101 by fasteners. The base 101 is filled with lubricating oil, allowing various bearing components such as the worm gear 31 and worm 32 to be immersed in the lubricating oil for lubrication.

[0029] In this embodiment, a sealing plate seat 17 is respectively provided on one side of the outer wall of the transmission housing 1 on the side of the meat grinder shaft 4 and the slicer shaft 5. The sealing plate seat 17 passes through the side wall of the transmission housing 1 and is respectively sleeved on the meat grinder shaft 4 and the slicer shaft 5 through the bearing. The sealing plate seat 17 has a hole in the center for the meat grinder shaft 4 and the slicer shaft 5 to pass through horizontally. A sealing sleeve is also provided in the sealing plate seat 17 to seal the bearing side and the hole to prevent lubricating oil from overflowing.

[0030] In this embodiment, a bearing holder 11 is integrally formed above the worm gear 32 within the transmission housing 1. A rotating bearing is fixedly mounted in the bearing holder 11, and the inner ring of the rotating bearing is positioned at the upper shaft end of the worm gear 32 to achieve positioning of the worm gear 32. Positioning holders 12 are integrally formed at both ends of the inner cavity of the transmission housing 1. Each positioning holder 12 has a groove in the middle for the spindle 33 to pass through. A bearing support 13 is longitudinally arranged between the two positioning holders 12 and both sides of the bearing holder 11. The two bearing supports 13 are rotatably connected to both ends of the spindle 33 via bearings to achieve support and positioning of both ends of the spindle 33.

[0031] In this embodiment, a protrusion 14 is provided on one inner wall of the inner cavity of the transmission housing. The protrusion 14 is located on the side away from the worm gear 32. The bottom of the protrusion 14 extends to the bottom of the base 101, and the top of the protrusion 14 is flush with the top of the base 101. A screw hole 141 for mounting the drive motor 2 is provided longitudinally through the protrusion 14.
