Description

Technical Field

[0001] This utility model relates to the field of meat grinders, and more particularly to a auger shaft conveying device for a defascia-removing meat grinder. Background Technology

[0002] A defascia meat grinder is a device that removes tendons and membranes from meat chunks and grinds them into meat strips. The auger shaft is the core component of the defascia meat grinder. The auger shaft is large in size and made of stainless steel, resulting in a heavy weight. Moreover, the auger blades welded on the outer wall of the auger shaft are quite sharp. Due to the weight and the air-cooling factor of the auger blades, it is not convenient for workers to disassemble and move the auger shaft. Therefore, it is necessary to develop an auger shaft handling device to assist workers in moving the auger shaft. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems in the existing technology and provide a auger shaft conveying device for a fascia-removing meat grinder.

A lifting device that moves along the guide rail is mounted on the guide rail. A support shaft parallel to the guide rail is fixed to the bottom of the lifting device. The support shaft is engaged with a mounting hole at the head of the auger shaft of the defascia-removing meat grinder. A pressure block that moves radially along the support shaft is provided at the head of the support shaft. A semi-threaded screw coaxial with the support shaft is screwed into the support shaft. The head of the semi-threaded screw has a conical surface that abuts against the bottom end of the pressure block.

[0006] The lifting device includes a rectangular tube, two vertical rods, and at least two supporting roller bearings. The rectangular tube is fitted onto a guide rail, and the supporting roller bearings are mounted on the upper inner side of the rectangular tube by pins. The supporting roller bearings roll along the guide rail. The two vertical rods are vertically welded to the bottom end of the rectangular tube, and the support shaft is welded to the bottom end of the vertical rods.

[0007] The support shaft has an external spline on its outer side at the middle, which engages with the internal spline on the inner side of the auger head of the fascia-removing meat grinder.

[0008] The top of the pressure block is an arc surface; the bottom of the pressure block is an inclined surface, and the inclination angle of the inclined surface is equal to the angle between the generatrix of the conical surface and the axis of rotation.

[0009] The support shaft has a centrally located circular through hole and a threaded hole, and the tail of the semi-threaded screw has an external thread that engages with the threaded hole. The head of the semi-threaded screw is inserted into the circular through hole.

[0010] Wherein, a head of the support shaft is provided with a guide hole having a convex-shaped longitudinal section along a radial direction of the support shaft, the pressing block is installed in the guide hole, and the guide hole is perpendicular to and communicates with the circular through hole.

[0011] Wherein, a tail end of the half-threaded screw rod is fixedly connected with a straight handle.

[0012] The beneficial effects of the present utility model are:

[0013] The auger shaft carrying device assists workers in disassembling, carrying and installing the auger shaft, facilitates workers to disassemble, assemble and carry the auger shaft, reduces the labor intensity of workers, and meanwhile, workers do not need to directly contact the auger blades on the outer side of the auger shaft, which reduces the risk of workers being cut.

Detailed Description of Embodiments

[0028] Hereinafter, the utility model will be described in detail with reference to the accompanying drawings in combination with embodiments.

[0029] As shown in Figures 1 to 12 , an auger shaft carrying device for a fascia-removing meat grinder comprises a moving trolley 1, a horizontally arranged guide rail 2 is mounted on the top of the moving trolley 1, a spreader 3 moving along the guide rail 2 is mounted on the guide rail 2, the spreader 3 comprises a section of rectangular tube 31, two vertical rods 32, and at least two supporting roller bearings 33, the rectangular tube 31 is sleeved on the guide rail 2, the supporting roller bearings 33 are mounted on the inner upper part of the rectangular tube 31 through pin shafts 34, the supporting roller bearings 33 roll along the guide rail 2 on the guide rail 2, and the two vertical rods 32 are vertically welded to the bottom end of the rectangular tube 31.

[0030] The bottom of the spreader 3 is fixedly connected with the support shaft 4 parallel to the guide rail 2, specifically, the support shaft 4 is welded to the bottom ends of the vertical rods 32.

[0031] The support shaft 4 is in plug fit with the mounting hole 1001 on the head of the auger shaft 100 of the fascia-removing meat grinder, furthermore, an external spline 41 is arranged on the outer side of the middle part of the support shaft 4, and the external spline 41 engages with the internal spline 1002 on the inner side of the head of the auger shaft 100 of the fascia-removing meat grinder.

[0032] The head of the support shaft 4 is provided with the pressing block 5 performing telescopic movement along the radial direction of the support shaft 4, the top end of the pressing block 5 is an arc surface 51, a guide hole 44 with a convex-shaped longitudinal section is formed along the radial direction of the support shaft 4 at the head of the support shaft 4, and the pressing block 5 is mounted in the guide hole 44.

[0033] A semi-threaded screw 6, coaxial with the support shaft 4, is screwed into the support shaft 4.
