Description

Technical Field

[0001] The utility model relates to the technical field of stringing machines, and more specifically, to an automatic cutting device for stringing machines. Background Art

[0002] Grilled skewers, as a delicacy, are deeply loved by consumers and are very common when dining out in the summer. In order to reduce the labor of threading the skewers, skewering machines came into being. However, if the machine only has the function of threading the skewers, the materials must be cut before entering the threading process. The labor of threading the skewers is still very large, so cutting equipment is also prepared for cutting.

[0003] The existing cutting device can cut large pieces of meat. After multiple cuts, the pieces of meat are suitable for skewering, which reduces the amount of pulling by workers. However, common cutting equipment only has the ability to cut. Although the meat after cutting is turned into pieces of meat, these pieces of meat will be piled together in a mess. Workers need to manually transfer the pieces of meat into the skewering mold quickly. Then, when the skewering operation is performed, workers still need to perform a certain degree of manual operation, which cannot achieve full automation of skewering. In addition, the contact between the pieces of meat and the conveying equipment and hands may cause contamination, resulting in unclean meat. Moreover, when the cutting tool cuts the meat, the pressure applied to the tool will be transmitted to the meat. After receiving the pressure from the tool, the meat that lacks fixation is easy to move with the tool. The cut meat is also easy to stick to the tool, affecting the cutting of the tool and causing a decrease in the quality of the cut pieces. In addition, most common cutting tools are simple blades. When cutting, the blade directly applies pressure to the meat. Raw meat has a certain softness and toughness, which is not easy to cut directly. Simple cutting in a single direction has a poor cutting effect. Utility Model Content

[0033] In this embodiment, when the equipment is used for automatic cutting, the arranged meat slices are stacked in the open mold 3, and then the open mold 3 is placed on the conveyor belt 2. The frame 1 supports the conveyor belt 2 to work, so that the conveyor belt 2 drives the open mold 3 to move. When the open mold 3 moves to the bottom of the cutting knife holder 5, the meat in the open mold 3 is cut by the cutting knife group 6, and the power push rod 7 drives the cutting knife group 6 to move under the support of the cutting knife holder 5, and the cutting edge 4 provides a moving space for the cutting knife, so that the cutting knife group 6 descends and moves repeatedly in the horizontal direction to cut the meat, and the two groups of cutting knives cooperate to cut in two directions in turn, and the meat in the open mold 3 is cut into pieces.

[0034] More specifically, before the cutting knife group 6 contacts the meat in the open mold 3 and cuts, the pressure frame 11 will first contact the meat under the support of the sliding frame 8 and the sliding rod 9, and the sliding rod 9 will move along the sliding frame 8 to adapt to the change in the spacing, and the pressure spring 10 will press the sliding rod 9, so that the sliding rod 9 pushes the pressure frame 11 to press the meat, thereby pressing the meat before cutting.

[0041] Please refer to Figure 4 As a further implementation of the pressure frame 11 mechanism: the pressure frame 11 includes an extension frame 20 and a pressure plate 21. The extension frame 20 is arranged at both ends of the pressure plate 21, and one end is connected to the pressure plate 21, and the other end is connected to the sliding rod 9. There are multiple pressure plates 21, and the pressure plates 21 cooperate with the cutting blade 14.

[0042] Specifically, when the pressure frame 11 applies pressure, the sliding rod 9 will drive the pressure plate 21 to move through the transmission of the extension frame 20, and the extension frame 20 will adapt to the shape of the opening mold 3, so that the pressure plate 21 contacts the meat inside the opening mold 3 and presses the meat tightly.

[0043] Please refer to Figure 4 As a further implementation of the pressure plate 21 mechanism: a clamping cone 22 is provided at the lower end of the pressure plate 21, and a plurality of groups of the clamping cones 22 are provided and are evenly arranged on the surface of the pressure plate 21 at equal intervals.

[0044] Specifically, the lower end of the pressure plate 21 contacts the meat through densely packed pressing cones 22, thereby increasing the friction between the pressure plate 21 and the meat and preventing displacement of the meat during cutting.

[0045] Please refer to Figure 6 As a further implementation of the sliding rod 9 mechanism: a limiting ring 23 is provided at the lower end of the sliding sleeve frame 8, and a limiting block 24 is provided at the upper end of the sliding rod 9, and the limiting block 24 cooperates with the limiting ring 23.

[0046] Specifically, when the sliding rod 9 moves in the sliding sleeve frame 8 , the limiting block 24 is restricted by the cooperation between the limiting ring 23 and the limiting block 24 , and the door-closing sliding rod 9 slides out of the sliding sleeve frame 8 .

[0048] Specifically, when the cutting tool holder 5 descends, the sliding frame 16 will drive the positioning rod 25 to descend together. At this time, the positioning rod 25 is inserted into the positioning groove 26. The alignment and positioning of the cutting structure and the opening mold 3 are completed through the cooperation between the positioning rod 25 and the positioning groove 26. If the positioning rod 25 is inserted into the positioning groove 26, it indicates that the opening mold 3 is aligned with the cutting structure, and the placement position of the opening mold 3 needs to be readjusted.

[0049] In summary, when the overall equipment is in use (or running):

[0050] When the equipment is used for automatic cutting, the arranged meat slices are stacked in the opening mold 3, and then the opening mold 3 is placed on the conveyor belt 2. The frame 1 supports the conveyor belt 2 to work, so that the conveyor belt 2 drives the opening mold 3 to move. When the opening mold 3 moves to the bottom of the cutting knife holder 5, the pressure cylinder 19 is started. Under the support of the support frame 18, the cutting knife holder 5 is located above the frame 1. By controlling the pressure cylinder 19 to work, the cutting knife holder 5 is driven to descend, and the meat in the opening mold 3 is cut by the cutting knife group 6. The power push rod 7 drives the cutting knife group 6 to move under the support of the cutting knife holder 5. The moving frame 12 cooperates with the sliding frame 16 through the sliding opening 17, and moves along the sliding opening 17 under the support of the sliding frame 16. The cutting blade 4 provides a moving space for the cutting knife group 6, so that the cutting knife group 6 descends and moves repeatedly in the horizontal direction to cut the meat. When the cutting knife group 6 cuts the meat, the driving motor 15 provides power to drive the cutting shaft 13 to drive the blade to rotate. When the cutting blade 14 contacts the meat, in addition to applying pressure by force, it will also rotate to make the cutting effect of the cutting blade 14 better. Through the cooperation of the two groups of cutting knife resistances, they cooperate with the cutting blade 4 in turn to cut in two directions, and the meat in the opening mold 3 is cut into pieces, and the meat pieces are neatly stacked into multiple strings. Then, under the action of the conveyor belt 2, the meat pieces cut into rows are moved to the stringing device under the maintenance of the opening mold 3.

[0051] When the cutting knife group 6 starts cutting, the cutting knife holder 5 descends, and the sliding frame 16 drives the positioning rod 25 to descend together. At this time, the positioning rod 25 is inserted into the positioning groove 26. The positioning rod 25 cooperates with the positioning groove 26 to complete the alignment and positioning of the cutting structure and the opening mold 3. If the positioning rod 25 is inserted into the positioning groove 26, it indicates that the opening mold 3 is aligned with the cutting structure, and the placement position of the opening mold 3 needs to be readjusted. When the door opening mold is aligned with the cutting structure, when the cutting knife holder 5 descends, under the support of the sliding sleeve frame 8 and the sliding rod 9, the pressure frame 11 will contact the meat in the opening mold 3 before the cutting knife group 6, and the sliding rod 9 will move along the sliding sleeve frame 8 to adapt to the gap. The distance changes, and the pressure spring 10 will press the sliding rod 9, so that the sliding rod 9 pushes the pressure frame 11 to press the meat. When the pressure frame 11 applies pressure, it will drive the pressure plate 21 to move through the transmission of the extension frame 20. The extension frame 20 will adapt to the shape of the opening mold 3, so that the pressure plate 21 contacts with the meat inside the opening mold 3, and the lower end of the pressure plate 21 contacts with the meat through dense compression cones 22, thereby strengthening the friction between the pressure plate 21 and the meat, and pressing the meat before cutting to avoid displacement of the meat during cutting. In addition, when the sliding rod 9 moves in the sliding frame 8, the limit block 24 is restricted by the cooperation of the limit ring 23 and the limit block 24, and the closing sliding rod 9 slides out of the sliding frame 8.

[0052] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
