[0003] For example, the utility model patent with the patent number CN202321969543.5, the application date of July 25, 2023, and the name of "A Lateral Telescopic Fixture for Pastry Foods" has the following technical solution: The present utility model discloses a lateral telescopic fixture for pastry foods, including a clamping mechanism, which includes a row of clamping pieces at the same horizontal height, and each pair of clamping pieces is driven by a finger cylinder; a gathering mechanism, the finger cylinders are commonly sleeved with a horizontal sliding rod, and the finger cylinders are also assembled through a zigzag connecting rod. The zigzag connecting rod includes several straight rods that are sequentially connected end to end in an axis. An included angle is formed between adjacent straight rods, and two spaced straight rods are parallel to each other. The finger cylinder has a translational degree of freedom on the sliding rod; a pressing mechanism, which has a horizontal pressing rod. The horizontal pressing rod passes through between each pair of clamping pieces, and the horizontal pressing rod has a vertical lifting degree of freedom. Each clamping piece in the above patent is connected by a finger cylinder. When the number of clamping pieces is large, many finger cylinders will be required, which will not only increase the cost of the entire mechanism, but also increase the weight of the entire clamping mechanism, and the structure and air circuit are also relatively cumbersome.

[0030] Embodiment 1
[0031] As Figures 1 - 7 shown, a multi-jaw clamping assembly includes a mounting frame, a driving motor, a pulling shaft, and multiple groups of jaws. The driving motor includes a first driving motor 21 and a second driving motor 22. The two driving motors are respectively installed at both ends of the mounting frame. The pulling shaft includes a first pulling shaft 23 and a second pulling shaft 24. The two pulling shafts are located inside the mounting frame, and one end of the first pulling shaft 23 and the second pulling shaft 24 are both connected to the output end of a driving motor; each group of jaws includes a left jaw 25 and a right jaw 26. The left jaw 25 and the right jaw 26 are connected by a rotating shaft 216. The first pulling shaft 23 is connected to all the left jaws 25 in multiple groups of jaws, and the second pulling shaft 24 is connected to all the right jaws 26 in multiple groups of jaws. The two driving motors respectively drive the two pulling shafts to move in opposite directions. The two pulling shafts drive the multiple left jaws 25 and multiple right jaws 26 connected to them to move in opposite directions. Since the left jaw 25 and the right jaw 26 in a group of jaws are hinged, when the left jaw 25 and the right jaw 26 move in opposite directions, the opening and closing of a group of jaws are realized.
[0032] The clamping assembly of the present application can realize the unified control of multiple groups of jaws. The multiple groups of jaws cooperate with each other and move synchronously under the drive of the motor and the pulling shaft. Its transmission structure is simplified, and the synchronism is significantly improved compared with the prior art.
[0033] Embodiment 2
[0034] As Figures 1 - 7As shown in the figure, a multi-jaw clamping assembly includes a mounting bracket, a driving motor, a pulling shaft, and multiple groups of jaws. The driving motor includes a first driving motor 21 and a second driving motor 22. The two driving motors are respectively installed at both ends of the mounting bracket. The pulling shaft includes a first pulling shaft 23 and a second pulling shaft 24. The two pulling shafts are located inside the mounting bracket, and one end of the first pulling shaft 23 and the second pulling shaft 24 are both connected to the output end of a driving motor. Each group of jaws includes a left jaw 25 and a right jaw 26. The left jaw 25 and the right jaw 26 are connected by a rotating shaft 216. The first pulling shaft 23 is connected to all the left jaws 25 in multiple groups of jaws, and the second pulling shaft 24 is connected to all the right jaws 26 in multiple groups of jaws. The two driving motors respectively drive the two pulling shafts to move in opposite directions. The two pulling shafts drive the multiple left jaws 25 and multiple right jaws 26 connected to them to move in opposite directions. Since the left jaw 25 and the right jaw 26 in a group of jaws are hinged, when the left jaw 25 and the right jaw 26 move in opposite directions, the opening and closing of a group of jaws are realized.
[0035] The mounting bracket includes a mounting upper plate 27, a mounting left plate 28, a mounting right plate 29, a mounting front plate 210, and a mounting rear plate 211. Both ends of the mounting upper plate 27 are connected to the mounting left plate 28 and the mounting right plate 29. Both ends of the mounting front plate 210 and the mounting rear plate 211 are respectively connected to the mounting left plate 28 and the mounting right plate 29. The first driving motor 21 and the second driving motor 22 are respectively fixed on the mounting left plate 28 and the mounting right plate 29. The mounting upper plate 27, the mounting left plate 28, the mounting right plate 29, the mounting front plate 210, and the mounting rear plate 211 enclose together to form a frame structure. The two pulling shafts are located inside the frame structure. The first driving motor 21 is fixed on the outer surface of the mounting left plate 28. The first driving motor 21 can drive the first pulling shaft 23 to perform a horizontal reciprocating motion, and the second driving motor 22 can drive the second pulling shaft 24 to perform a horizontal reciprocating motion.
[0036] Two parallel mounting through holes are provided on both the mounting left plate 28 and the mounting right plate 29. The output end of the first driving motor 21 passes through the mounting through hole on the mounting left plate 28 and is connected to the left end of the first pulling shaft 23. The output end of the second driving motor 22 passes through the mounting through hole on the mounting right plate 29 and is connected to the right end of the second pulling shaft 24.
[0037] Multiple protruding guide columns 212 are provided on the pulling shaft. The multiple guide columns 212 are evenly distributed on the same horizontal plane of the pulling shaft. The guide column 212 has a cylindrical structure and is used to drive the left jaw 25 or the right jaw 26 to move.
[0038] The left jaw 25 includes a left jaw body at the lower part and a left connecting body at the upper part. The right jaw 26 includes a right jaw body at the lower part and a right connecting body at the upper part. The tops of all the left connecting bodies in multiple groups of jaws are connected to the left connecting rod 213, and the tops of all the right connecting bodies in multiple groups of jaws are connected to the right connecting rod 214. The left jaw body and the right jaw body in the same group of jaws are matched, and guiding holes 215 are provided in the middle of the left connecting body and the right connecting body. The middle parts of the left jaw 25 and the right jaw 26 are hinged to form a group of jaws. The left jaw body and the left connecting body can be of a split structure or an integral structure. Since there is no relative movement between the two and they both act simultaneously, the integral structure is more suitable. The function of the left connecting rod 213 is to uniformly control the actions of all the left jaws 25, and the right connecting rod 214 can uniformly control the actions of all the right jaws 26, so that the left jaws 25 and the right jaws 26 in all the jaws move synchronously.
[0039] The functions of the left jaw body and the right jaw body are to pick up wontons when they are closed and put down wontons when they are opened. Therefore, the specific shapes of the left jaw body and the right jaw body can be adaptively designed according to the shapes of the wontons to be picked up. This application does not make specific restrictions on this, as long as the basic functions of picking up and putting down can be achieved.
[0040] The guiding holes 215 are used to cooperate with the guiding columns 212 on the pulling shafts. The guiding columns 212 extend into the guiding holes 215. The two pulling shafts move horizontally in opposite directions at the same time, and then drive the same ends of the left jaw 25 and the right jaw 26 to move in opposite directions, and finally drive all the left jaws 25 and the right jaws 26 to close or open simultaneously.
[0041] The guiding holes 215 are of an elliptical structure, and the size of the guiding holes 215 is larger than the size of the guiding columns 212. The elliptical shape enables the guiding columns 212 to have a certain movement space in the larger guiding holes 215.
[0042] A rotating shaft 216 is connected to the middle parts of the left jaw 25 and the right jaw 26 in the same group of jaws. Both ends of the rotating shaft 216 are connected to the front mounting plate 210 and the rear mounting plate 211. The left jaw 25 and the right jaw 26 are simultaneously sleeved on the rotating shaft 216, so that an opening and closing action similar to that of scissors can be achieved.
[0043] A plurality of rotating shafts 216 are fixed between the front mounting plate 210 and the rear mounting plate 211, and the centers of all the rotating shafts 216 are located on the same horizontal plane.
[0044] The first driving motor 21 drives the first pulling shaft 23 to move in the horizontal direction. The first pulling shaft 23 drives the upper ends of all the left clamping jaws 25 sleeved thereon to move in the same direction as the first pulling shaft 23 through the guiding columns 212. Since the middle parts of the left clamping jaws 25 and the right clamping jaws 26 in the same group are hinged, the lower ends of the left clamping jaws 25 will move in the opposite direction to the movement direction of the first pulling shaft 23 at this time. The second driving motor 22 drives the second pulling shaft 24 to move horizontally in the opposite direction to the first pulling shaft 23. The second pulling shaft 24 sleeves all the right clamping jaws 26 through the guiding columns 212 thereon, and drives the upper ends of the right clamping jaws 26 to move in the same direction as the second pulling shaft 24. Then the lower ends of the right clamping jaws 26 move in the opposite direction to the second pulling shaft 24. Finally, all the left clamping jaws 25 and all the right clamping jaws 26 perform the closing and opening actions simultaneously. When closed, the clamping function is realized; when opened, the discharging function is realized.
[0045] The clamping assembly of the present application can realize the unified control of multiple groups of clamping jaws. The multiple groups of clamping jaws cooperate with each other and move synchronously under the drive of the motor and the pulling shaft. Its transmission structure is simplified, and the synchronism is significantly improved compared with the prior art.
[0046] In the present application, two pulling shafts drive the left clamping jaws 25 and the right clamping jaws 26 respectively, and then drive all the left clamping jaws 25 and the right clamping jaws 26 to move synchronously through the left connecting rod 213 and the right connecting rod 214, thereby simplifying the overall transmission structure.
[0047] In the present application, a plurality of rotating shafts 216 are arranged between the front mounting plate 210 and the rear mounting plate 211. The multiple groups of clamping jaws are fixed in the mounting frame. Since the middle parts of the left clamping jaws 25 and the right clamping jaws 26 in the same group are both sleeved on the rotating shaft 216, the actions similar to the opening and closing of scissors can be conveniently realized.
[0048] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
