Description

TECHNICAL FIELD

[0002] In the process of processing operation, it is often necessary to involve the operation of pre-cutting the target object, and the pre-cutting device is an indispensable part of modern production line, and at present, there is a lack of equipment for pre-cutting the target object, which leads to the inconvenience of pre-cutting the object.

[0003] For example, in the current Pu'er tea market, compact tea (such as tea cakes or tea bricks) is the mainstream. Such tea has a longer aroma preservation time, better antioxidant properties, and is easy to store for a long time, making it easier to store and transport. However, such compact tea is difficult to be processed again. Since the tea cake is hard, it is not easy to cut into small pieces, so it is necessary to consider designing a pre-cutting device that can be used for secondary processing. Although there are several pre-separation processing schemes at present, these schemes require manual removal after processing a tea cake, and then processing the next tea cake. Such processing method is slow and low in efficiency. Furthermore, there is little research on the pre-separation equipment for target objects, and the pre-cutting device should be researched to provide technical options for the application of future processing industry.

As shown in Figure 13 Seven connecting pins 46 pass through both ends of two connecting rods I 47, both ends of a first connecting rod II 52, and one end of a second connecting rod II 52 for connection to the rack 8 and the connecting rod connecting piece 48. The other end of the second connecting rod II 52 is connected to the connecting rod speed reduction mechanism 4 through the speed reducer-connecting rod connecting shaft 53, and a gasket 54 is arranged at the connection to reduce the friction during rotation, a total of 8 pieces. The connecting rod II 52 is the driving shaft, and the connecting rod I 47 acts as a swing rod, connected to the connecting rod speed reduction mechanism 4 through the speed reducer-connecting rod connecting shaft 53. The large torque delivered by the speed reduction mechanism will ensure that the target object will not be stuck due to resistance during cutting. The connecting rod connecting piece 48 and the rotating plate 49 are connected by 8 screws, allowing the connecting rod mechanism to rotate the rotating plate 49. Two guide pieces 50 are connected to the rotating plate 49 by 6 screws, which can ensure that the target object does not deviate during movement, stably slides into the circular groove of the rotating plate, and ensures that the target object can also stably slide to the discharge guide disc 13 after processing. The guide piece 50 is divided by a point on the axis of the rotating plate, and the left end of the guide piece is shorter than the right end, which can effectively prevent interference with the opened baffle mechanism 21. As shown in Figure 14 The jacking mechanism 51 includes a jacking disc 55, a jacking column 57, and a jacking adjusting ring 58. As shown in Figure 15As shown, the outer circumferential upper and lower segments of the two jacking columns 57 are threaded, and are matched with the jacking columns 57 and the jacking adjusting ring 58, respectively. The jacking height can be adjusted by adjusting the position of the jacking adjusting ring 58.

[0074] Figures 23-28 The working flowchart of the present application. The working flowchart of the present application is divided into three parts, 1-feeding, 2-cutting, and 3-storing. Taking the processing target object tea cake as an example, wherein Figures 23-25 The working flowchart of (1-feeding). As shown, Figure 23 The tea cake 82 is placed in the feeding bin 20 of the feeding device 2, and when the cylinder 15 has not been pushed, the baffle mechanism 21 blocks the tea cake 82 from sliding downward; at this time, the diffuse reflection sensor 10 close to the feeding device 2 side of the connecting rod base mechanism 7 senses that the connecting rod I 47 in the connecting rod base mechanism 7 reaches the specified position, the power source 29 stops rotating, the connecting rod base mechanism 7 stops moving, and the cylinder 15 starts to push. Enter the working flow 1-2, as shown, Figure 24 Under the action of the pushing force of the cylinder 15, the tea cake 82 slides downward, the baffle mechanism 21 is opened due to the pushing force of the cylinder, and the tea cake continues to slide downward and enters the working flow 1-3. As shown, Figure 25 The tea cake slides into the groove of the rotating plate 49, and when the cylinder 15 has not been retracted, the remaining tea cake is blocked by the wall of the feeding bin 20, and after the cylinder 15 is retracted, the remaining tea cake is blocked by the baffle mechanism 21 which has returned to the original position. At this time, the (1-feeding) action is completed, and the mechanism starts to enter the (2-cutting) flow. As shown, Figure 26As shown, the mechanism starts cutting the tea cake 82, at this time the pressing mechanism 5 generates a pressing force on the tea cake, preventing the tea cake from being removed from the mechanism due to cutting force. After the (2-cutting) action is completed, the tea cake surface is cut into 6 cutting grooves, about 10-15mm deep, after cutting, the mechanism enters the next working process (3-storing). As shown Figure 27 As shown, the connecting rod base mechanism 7 continues to move, the diffuse reflection sensor 10 on the other side of the connecting rod base mechanism 7 senses that it reaches the specified position, the power source 29 stops rotating, and the connecting rod base mechanism 7 stops; the push rod-reset mechanism 6 makes the lifting mechanism 51 lift, and the tea cake 82 leaves the groove and continues to slide under the action of gravity. As shown Figure 28 As shown, after passing through the discharging guide disc 13, the tea cake 82 after cutting is stored in the storage bin 14.

[0075] According to the above technical solution, the connecting rod base mechanism 7 is used as a moving mechanism, and the motion trajectory of the connecting rod mechanism is used to realize the assembly line operation in a small space. Because of the motion trajectory of the connecting rod mechanism, the tea cake enters the next working process by using gravity when pushing and feeding, and the inclination angle of the tea cake sliding is small when feeding, so that the tea cake is smoothly conveyed to the groove of the connecting rod base mechanism 7. After cutting, the inclination angle of the tea cake sliding is large, and the tea cake can quickly enter the storage bin 14. The assembly line design improves the efficiency of the mechanism as a whole and makes it more stable. The connecting rod reduction mechanism 4 reduces the number of motors used in the application, making the application easier to control. The large torque and slow speed provided by the speed reducer make the cutting process very stable, and the tea cake is not easy to be removed. The sawing device 3 has small resistance due to its own characteristics, and the pressing force provided by the pressing mechanism 5 makes the operation of the application more efficient and safe.
