Description

Technical Field

[0001] The utility model relates to the technical field of chicken leg processing, in particular to a driving mechanism of a chicken leg cutting machine. Background Technique

[0002] At present, most chicken leg cutting processes in the market are carried out manually. Many processes are required during the whole leg cutting process, and a large number of personnel are needed to complete it. For example, it is necessary to manually use a knife to cut the chicken leg along the joint of the chicken leg. Due to manual operation, the cutting position is unstable, the cutting depth is unstable, and improper operation of the operator is likely to affect the appearance and weight of the product. In the above production process, the slaughter volume per day is large, so the labor intensity of the staff is high. Moreover, since the staff needs to use a knife, in all processes of whole leg cutting, if the staff does not use the knife correctly or makes a mistake during the use of the knife, it is very easy to cause personnel injury accidents. Therefore, the above personnel all need a long time to operate proficiently, and the requirements for personnel are relatively strict, which affects the production capacity.

[0003] Chinese Patent 202321836289.1 discloses "A device for cutting the thigh and calf of poultry", with the publication number CN220211705 U. The device includes a leg conveying mechanism for conveying the poultry leg; a leg limiting mechanism arranged below the leg conveying mechanism for limiting the poultry leg to prevent the poultry leg from rotating; a leg cutting mechanism arranged on one side of the leg limiting mechanism for cutting the thigh and calf of the poultry; and a slitting mechanism for increasing the bone slit at the joint of the thigh and calf of the poultry to facilitate accurate cutting by the leg cutting mechanism. However, this device has some defects: the leg conveying mechanism and the leg limiting mechanism of this device are both independent transmission mechanisms, and the leg conveying mechanism and the leg limiting mechanism cannot operate synchronously. Especially when running at high speed, the phenomenon of dislocation between the leg conveying mechanism and the leg limiting mechanism is likely to occur, resulting in inaccurate cutting of some chicken legs and becoming defective products. Content of the Utility Model

[0004] In order to solve the problems of the above-mentioned prior art, the utility model provides a driving mechanism of a chicken leg cutting machine, which can synchronize the chicken leg hook with the leg limiting mechanism, so that the leg limiting mechanism can firmly fix the chicken legs on the chicken leg hook without omission.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a driving mechanism of a chicken leg splitter, comprising a first conveying device for conveying a chicken leg hook and a second conveying device for conveying a leg limiting mechanism, the first conveying device comprising a first driving sprocket and a first driven sprocket rotatably connected to a splitter support frame, a first chain sleeved on the first driving sprocket and the first driven sprocket, and the chicken leg hook is fixedly connected to the first chain; the second conveying device comprises a second driving sprocket and a second driven sprocket rotatably connected to the splitter support frame, a second chain sleeved on the second driving sprocket and the second driven sprocket, and the leg limiting mechanism is fixedly connected to the second chain; the first driving sprocket is transmission-connected to the second driving sprocket via a synchronization device.

[0006] With the above structural design, when the chicken leg hook is transported to the top of the leg limiting mechanism, the leg limiting mechanism clamps the chicken leg; the chicken leg hook is synchronized with the leg limiting mechanism, and through a constant speed ratio, the chicken leg hook can accurately run to the top of the leg limiting mechanism, so that the leg limiting mechanism can clamp the chicken leg on the chicken leg hook without omission.

[0007] Preferably, the synchronization device includes a transmission shaft fixedly connected to the second driving sprocket, a driving bevel gear tightly mounted on the transmission shaft, a driven bevel gear meshing with the driving bevel gear, a linkage shaft fixedly connected to the driven bevel gear, a driven synchronous pulley fixedly connected to the linkage shaft, an active synchronous pulley fixedly connected to the first driving sprocket, and a synchronous belt mounted on the driven synchronous pulley and the active synchronous pulley, the transmission shaft and the linkage shaft are both rotatably connected to the bevel gear box, and the bevel gear box is fixedly connected to the splitter support frame; a tensioner for tensioning the belt is provided on the synchronous belt.

[0008] By adopting the above structural design, the first driving sprocket is connected to the second driving sprocket through the bevel gear set and the synchronous belt pulley, so that the first driving sprocket and the second driving sprocket are non-slip when working, have a constant transmission ratio, and have accurate transmission, smooth transmission and high transmission efficiency.

[0009] Preferably, the transmission shaft includes a first transmission shaft rotatably connected to the bevel gear box, a coupling fixedly connected to the first transmission shaft, and a second transmission shaft fixedly connected to the coupling via a locking sleeve, the driven bevel gear fastening sleeve is arranged on the first transmission shaft, and the second transmission shaft is fixedly connected to the second driving sprocket.

[0010] By adopting the above-mentioned structural design, the coupling can reduce the error when the linkage shaft and the transmission shaft are connected; when it is necessary to debug the initial positions of the first transmission device and the second transmission device, the locking sleeve can be removed, and then the second transmission shaft can be rotated, the second driving sprocket can rotate, and the first driving sprocket does not move, thereby making the initial position of the second transmission device correspond to the initial position of the first transmission device.

[0011] Preferably, a driving shaft is fixedly connected to the first driving sprocket, the driving shaft is drivingly connected to a first driving motor, and the first driving motor is fixedly connected to the support frame of the splitting machine.

[0012] With the above structural design, since the diameter of the first driving sprocket is generally larger than that of the second driving sprocket, driving the second driving sprocket to rotate by the first driving sprocket can generate a greater driving force.

[0013] Preferably, the transmission shaft is drivingly connected to a reduction motor, a expansion sleeve is inserted into the inner hole of the driven synchronous pulley, and the expansion sleeve is sleeved on the linkage shaft.

[0014] With the above structural design, the first conveying device is relatively light, and the chicken legs on the leg limiting mechanism will collide with the cutting device. Driving the first driving sprocket by the second driving sprocket can reduce the influence of the jamming caused by the collision, and the driving is more stable.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1) The device can synchronize the chicken leg hook with the leg limiting mechanism, so that the leg limiting mechanism can clamp the chicken legs on the chicken leg hook without omission.

[0017] 2) The device is convenient for debugging and aligning the initial positions of the first conveying device and the second conveying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When it is necessary to debug the initial positions of the first conveying device and the second conveying device accordingly, the locking sleeve 403 can be removed, and then the second transmission shaft 404 can be rotated. There is a gap between the inner wall of the locking sleeve 403 and the second transmission shaft 404, which can ensure the normal rotation of the second transmission shaft 404, and then the second driving sprocket 31 can be rotated.

The transmission shaft 41 passes through the keyway hole of the reduction motor 7 and is installed in the keyway hole of the reduction motor 7. A wedge-shaped slot matching the shrink disc 8 is opened on the inner hole wall of the driven synchronous pulley 51.

[0035] When the device is in use, the reduction motor 7 is started, and the reduction motor 7 drives the transmission shaft 41 to rotate. The transmission shaft 41 rotates to drive the second driving sprocket 31 to rotate. The second driving sprocket 31 drives the second driven sprocket 32 to rotate through the second chain 33, so as to realize that the second conveying device drives the leg limiting mechanism to perform rotary conveying; the reduction motor 7 drives the linkage shaft 42 to rotate through the bevel gear set. The driven synchronous pulley 51 fixedly connected to the linkage shaft 42 rotates. The driven synchronous pulley 51 drives the driving synchronous pulley 52 to rotate through the synchronous belt 53, so that the first driving sprocket 21 fixedly connected to the driving synchronous pulley 52 rotates.
