Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a clamping mechanism for a chopping machine. Background Art

[0002] The catering industry often needs to use slicing tools to cut steaks, ribs, and fresh meat into the slices required by users. For the catering industry with large supply, there are now slicing machines on the market, which refer to equipment that cuts steaks, ribs, fresh meat, and other medium and large-sized ingredients into slices, segments, and cubes through the coordination of the transmission system and the movement of the knife group. Slicing machines are widely used in meat processing plants, family steak production, meat processing in fresh supermarkets, and central kitchen production and processing of various sizes.

Further, the gripper 204 includes a gripper shaft 205 and a shaft 206, and a torsion spring 207 is fixedly installed on the side surface of the gripper shaft 205. The feed clamping mechanism adopts a manual clamping method, and the handle is manually pulled to achieve clamping by the rebound force of the torsion spring 207, which is safe and controllable, and the control method is driven by a servo motor, which can achieve precise control. Most of the existing cutting machine feeding clamping mechanisms adopt the above-mentioned manual clamping claw structure. However, the above-mentioned patented technical solution and the handle of the existing cutting machine on the market are both installed on the back of a clamping piece, that is, a single-side cantilever installation method is adopted.

In this way, the connecting piece at the root of the handle is often relatively weak, and deformation and damage are easily caused during the reciprocating manual pulling of the handle.

[0004] Therefore, it is necessary to develop a cutting machine clamping mechanism to address the above defects. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0031] Example 1

[0032] like Figures 1 to 5As shown, a clamping mechanism for a row chopper is consistent with the prior art, connected to the feed drive mechanism of the row chopper body 8 through a connecting plate 9, and includes a housing body 1, a main shaft 2, a clamp assembly 3, a tail rod 4, a torsion spring 5 and a front baffle 6. The housing body 1 includes two side walls and three rods connected in the middle, the two ends of the main shaft 2 are fixedly connected to the side walls of the housing body 1, the clamp assembly 3 is rotatably mounted on the main shaft 2, the spiral portion of the torsion spring 5 is sleeved on the main shaft 2, the head end rod of the torsion spring 5 is pressed on the stop rod 303 of the clamp assembly 3, and the tail end rod of the torsion spring 5 is pressed tightly on the tail rod 4. The front baffle 6 blocks the front end surface of the housing body 1, and the front baffle 6 is provided with a vertical clamp through hole 601 at the position where the finger clamp of the clamp assembly 3 protrudes. The important difference between the technical solution of the utility model and the prior art is that the chuck assembly 3 includes a middle chuck piece, a side chuck piece 301, a handle 302 and a stop stick 303. The front ends of the middle chuck piece and the side chuck piece 301 are respectively provided with finger chucks passing through the chuck through hole 601, and the finger chucks cooperate with the front baffle plate 6 to complete the clamping of the meat to be cut. The plurality of middle chuck pieces are arranged side by side and spaced apart, and the two side chuck pieces 301 are respectively located at the two ends, and the backs of the two side chuck pieces 301 are both protruding upwards and are respectively connected to the two ends of the handle 302 by bolts.

[0033] By adding a side clamping piece 301 with a connecting protrusion, the ends of the handle 302 can be fixed at both ends. Compared with a single-end fixation, the connection strength is large and the structural stability is good, avoiding the deformation of the connecting protrusion of the side clamping piece 301 during the reciprocating pulling process. The clamping mechanism of the chopping machine of the utility model increases the connection strength of the handle part, and the clamping assembly structure is more stable and not easy to be deformed and damaged.

[0034] In a specific implementation of this embodiment, the handle 302 is sleeved with a polytetrafluoroethylene plastic or rubber sheath.

[0035] In a specific implementation of this embodiment, Figures 3 to 5 As shown, the main rotating shaft 2 includes a core shaft and a spacer sleeved on the core shaft. The number of the spacers is multiple and they are arranged at intervals between the through holes of the middle chuck piece and the side chuck piece 301. The through holes of the middle chuck piece and the side chuck piece 301 can be rotatably sleeved on the core shaft of the main rotating shaft 2. The two ends of the core shaft of the main rotating shaft 2 pass through the side wall of the shell frame body 1 and are fixed to the shell frame body 1 by screws. The structure of the stop rod 303 is consistent with that of the main rotating shaft 2, and the spacer sleeve is also used to space the middle chuck piece and the side chuck piece 301. The two ends of the core shaft of the stop rod 303 are fixed to the through holes of the side chuck piece 301 by screws, and the spacer sleeve of the stop rod 303 receives the head end rod of the torsion spring 5.

[0036] By arranging the main rotating shaft 2 and the stop rod 303 in the form of a spacer sleeve and a core shaft, the middle clamping piece, the side clamping piece 301 and the torsion spring 5 can be installed more conveniently, avoiding the middle clamping piece from being skewed.

[0037] In a specific implementation of this embodiment, Figures 2 to 5 As shown, the clamping mechanism of the chopping machine of the utility model also includes an adjusting plate 7. The front baffle plate 6 is connected to the side wall of the shell frame body 1 through the pin bolt 602 at the top. The root of the adjusting plate 7 is connected to the rear side wall of the front baffle plate 6 through bolts. A positioning pin 701 is arranged at the outer end of the adjusting plate 7. An adjusting hole group 102 consisting of a plurality of positioning pin holes is provided on the side wall of the shell frame body 1. The center of the arc where the center of each positioning pin hole is located is arranged on the axis line of the pin bolt 602. The adjusting plate 7 is made of a highly elastic stainless steel sheet material. When the positioning pin 701 needs to be disengaged from the adjusting hole group 102, the outer end of the adjusting plate 7 is bent inward to drive the positioning pin 701 out of the positioning pin hole, and the adjusting plate 7 is moved upward or downward so that the positioning pin 701 is aligned with the positioning pin hole at other positions, and the adjusting plate 7 is released. During the resetting process of the adjusting plate 7, the positioning pin 701 is reinserted into the newly aligned positioning pin hole. In this process, the adjustment plate 7 drives the front baffle plate 6 to swing around the pin bolt 602, which can be adapted to different clamped end shapes of meat products.

[0038] Specifically, the positioning pin 701 is a conical pin.

[0039] By setting the adjusting plate 7, the front baffle 6 can be adjusted to swing around the pin bolt 602, thereby being able to adapt to different clamped end forms of meat products, ensuring a firm and reliable clamping. By setting the positioning pin 701 as a conical pin, it can be smoothly removed from and inserted into the positioning pin hole.

[0040] Example 2

[0041] In the above embodiment 1, like the existing chopping machine clamping mechanism, for meat products of different clamping thicknesses, the force applied by the finger clamp of the clamp assembly 3 is also different. For meat products with thicker clamping parts, the operator often needs to pull the handle 302 backward very hard to make the finger clamp open enough. For meat products with thinner clamping parts, the clamping force applied by the finger clamp on the meat is often too small, and the clamping is not stable. Therefore, based on the above embodiment 1, the clamping force is optimized and improved to form this embodiment.

[0042] like Figures 3 to 6As shown, the tail rod 4 is provided with a guide ring groove 401 at the position where the tail end rod of the torsion spring 5 is pressed. Specifically, the tail rod 4 includes a tail rod core shaft 404 and a long sleeve, and the long sleeve is rotatably sleeved on the tail rod core shaft 404 and spaced between the side walls of the frame body 1. The guide ring groove 401 is provided on the outer wall of the long sleeve, and the depth of the guide ring groove 401 gradually changes along the circumferential angle, for example, gradually becomes deeper. That is, the guide ring groove 401 is a ring groove of unequal depth.

[0043] A guide ring groove 401 is provided on the tail rod 4 to accommodate and limit the tail end rod of the torsion spring 5, thereby preventing the tail end rod of the torsion spring 5 from swinging and generating noise during the manual pulling of the handle 302; the tail rod 4 composed of the tail rod core shaft 404 and the long sleeve enables the long sleeve to rotate relative to the tail rod core shaft 404. During the rotation, the tail end rod of the torsion spring 5 enters the guide ring groove 401 with different depths, thereby changing the preset torque value of the torsion spring 5.

[0044] In a specific implementation of this embodiment, Figures 3 to 5 As shown, a wrench area 402 is provided at one end of the long sleeve, and the wrench area 402 includes two groups of concave platforms symmetrically arranged on the outer wall of the long sleeve. The circumferential angles of the two groups of concave platforms differ by 90 degrees. The distance between the two concave platforms in each group matches the working opening spacing of the open-end wrench.

[0045] Specifically, if Figures 3 to 5 As shown, a marking area 403 is provided at one end of the long sleeve, and the marking area 403 is a circular area that uses numbers or arrows to mark the size of the crimping force of the long sleeve on the tail end rod of the torsion spring 5.

[0046] By adding a wrench area 402 at one end of the long sleeve, it is convenient to use an open-end wrench to adjust the circumference of the long sleeve; by adding an identification area 403 at one end of the long sleeve, it is convenient to observe the crimping force of the tail end rod of the torsion spring 5 intuitively during the rotation of the long sleeve.

[0047] The working process of the clamping mechanism of the chopping machine of this embodiment is as follows: first, the inclination angle of the front baffle plate 6 is adjusted according to the shape characteristics of the clamped end of the meat to be cut, and the outer end of the adjustment plate 7 is bent inward during adjustment to drive the positioning pin 701 to disengage from the positioning pin hole, and the adjustment plate 7 is moved upward or downward to align the positioning pin 701 with the positioning pin hole at other positions, and the adjustment plate 7 is released. During the resetting process of the adjustment plate 7, the positioning pin 701 is reinserted into the newly aligned positioning pin hole. In this process, the adjustment plate 7 drives the front baffle plate 6 to swing around the pin bolt 602, which can be suitable for different clamped end shapes of meat. After adjusting the inclination angle of the front baffle plate 6, observe the thickness of the clamping part of the meat. If it is thin, an open-end wrench needs to be inserted into the wrench area 402 to rotate and adjust the long sleeve so that the larger indication in the marking area 403 faces directly upward. If the thickness of the clamping part of the meat is thick, perform the reverse operation. After the circumferential angle of the long sleeve is adjusted, the tail end rod of the torsion spring 5 is pressed tightly in the guide ring groove 401, that is, the long sleeve is pressed tightly on the tail rod core shaft 404, and the long sleeve does not rotate by itself. The handle 302 is manually pulled to open the finger clamp of the clamp assembly 3 to a sufficiently large opening, so as to complete the clamping of the meat product. The subsequent slicing operation is carried out.

[0048] In summary, by adding a side clamping piece 301 with a connecting protrusion, the end of the handle 302 can be fixed at both ends. Compared with single-end fixing, the connection strength is large and the structural stability is good, which avoids the deformation of the connecting protrusion of the side clamping piece 301 during the reciprocating pulling process. The clamping mechanism of the chopping machine of the utility model increases the connection strength of the handle part, and the structure of the clamping assembly is more stable and not prone to deformation and damage. In addition, by setting the main rotating shaft 2 and the stop rod 303 in a spacer sleeve matching the core shaft, the middle clamping piece, the side clamping piece 301 and the torsion spring 5 can be installed more conveniently to avoid the deflection of the middle clamping piece. By setting the adjustment plate 7, the front baffle plate 6 can be adjusted to swing around the pin bolt 602, so as to adapt to the different clamped end shapes of the meat, and ensure firm and reliable clamping. By setting the positioning pin 701 as a conical pin, it can be smoothly removed and inserted into the positioning pin hole. By opening a guide ring groove 401 on the tail rod 4, the guide ring groove 401 accommodates and limits the tail end rod of the torsion spring 5, which can prevent the tail end rod of the torsion spring 5 from swinging and generating noise during the manual pulling of the handle 302; the tail rod 4 composed of the tail rod core shaft 404 and the long sleeve allows the long sleeve to rotate relative to the tail rod core shaft 404. During the rotation, the tail end rod of the torsion spring 5 enters the guide ring groove 401 with different depths, thereby changing the preset torque value of the torsion spring 5. By adding a wrench area 402 at one end of the long sleeve, it is convenient to use an open-end wrench to adjust the circumference of the long sleeve; by adding an identification area 403 at one end of the long sleeve, it is convenient to observe the crimping force of the tail end rod of the torsion spring 5 during the rotation of the long sleeve.
