[0030] Example 1

[0031] like Figure 1 and Figure 2As shown, a spacing-adjustable clamping jaw for clamping wontons comprises a fixed plate 1, and a lateral active distance-adjusting device 2 is arranged on the lower surface of the fixed plate 1, and the lateral active distance-adjusting device 2 comprises a first motor 3 and a screw rod 4, wherein the first motor 3 is connected to the screw rod 4 and drives it to rotate, and the screw rod 4 is symmetrically provided with a positive thread segment 5 and a negative thread segment 6, and the positive thread segment 5 and the negative thread segment 6 are connected with a mounting plate 28, and the mounting plate 28 is connected with the clamping jaw 7. The lateral active distance-adjusting device 2 can adjust the distance between each longitudinal column of clamping jaws 7 in real time, and can meet the requirements of clamping wontons with different spacings, and the first motor 3 drives the screw rod 4 to rotate, and since the screw rod 4 is provided with a positive thread segment 5 and a negative thread segment 6, when the screw rod 4 rotates, the mounting plate 28 located on the positive thread segment 5 will move in the opposite direction with the mounting plate 28 located on the negative thread segment 6, and then the clamping jaw 7 connected with the mounting plate 28 will also move in the opposite direction, thereby achieving real-time adjustment of the spacing between one or more columns of clamping jaws 7.

[0032] The present application can achieve real-time adjustment of the spacing between the laterally distributed clamping jaws 7. After the wontons are clamped from the conveyor belt, the lateral spacing is adjusted before they are placed in the tray. This allows a set of clamping jaws 7 to be adapted to more trays, and also allows users to adjust the lateral spacing of the clamping jaws 7 in real time according to their own needs. The positive thread segment 5 and the reverse thread segment 6 are symmetrically arranged on the screw rod 4, which can conveniently and quickly realize the reverse movement of the clamping jaw 7, eliminating the guide plate and other structures in the prior art, and can adjust the position of the clamping jaw 7 in real time and at any distance.

[0033] Example 2

[0034] like Figure 1 and Figure 2 As shown, a spacing-adjustable clamping jaw for clamping wontons comprises a fixed plate 1, and a lateral active distance-adjusting device 2 is arranged on the lower surface of the fixed plate 1, and the lateral active distance-adjusting device 2 comprises a first motor 3 and a screw rod 4, wherein the first motor 3 is connected to the screw rod 4 and drives it to rotate, and the screw rod 4 is symmetrically provided with a positive thread segment 5 and a negative thread segment 6, and the positive thread segment 5 and the negative thread segment 6 are connected with a mounting plate 28, and the mounting plate 28 is connected with the clamping jaw 7. The lateral active distance-adjusting device 2 can adjust the distance between each longitudinal column of clamping jaws 7 in real time, and can meet the requirements of clamping wontons with different spacings, and the first motor 3 drives the screw rod 4 to rotate, and since the screw rod 4 is provided with a positive thread segment 5 and a negative thread segment 6, when the screw rod 4 rotates, the mounting plate 28 located on the positive thread segment 5 will move in the opposite direction with the mounting plate 28 located on the negative thread segment 6, and then the clamping jaw 7 connected with the mounting plate 28 will also move in the opposite direction, thereby achieving real-time adjustment of the spacing between one or more columns of clamping jaws 7.

[0035] like Figure 3 and Figure 4As shown, the positive thread segment 5 on the screw rod 4 includes a first positive thread zone 8, a second positive thread zone 9 and a third positive thread zone 10 distributed from the middle to the side, and the lead of the first positive thread zone 8 is smaller than the lead of the second positive thread zone 9, and the lead of the second positive thread zone 9 is smaller than the lead of the third positive thread zone 10; the reverse thread segment 6 includes a first reverse thread zone 11, a second reverse thread zone 12 and a third reverse thread zone 13 distributed from the middle to the side, and the lead of the first reverse thread zone 11 is smaller than the lead of the second reverse thread zone 12, and the lead of the second reverse thread zone 12 is smaller than the lead of the third reverse thread zone 13. The positive thread segment 5 and the reverse thread segment 6 are divided into a plurality of sections with different leads because in the process of adjusting the plurality of jaws 7 from the initial spacing to the new spacing, each jaw 7 needs to move a different distance, so the jaws 7 closer to the edge of the screw rod 4 have a longer distance to move, and the jaws 7 closer to the middle of the screw rod 4 have a shorter path to move.

[0036] like Figure 3 and Figure 4 As shown, the lead of the first positive thread zone 8 and the first reverse thread zone 11 is a, the lead of the second positive thread zone 9 and the second reverse thread zone 12 is 2a, and the lead of the third positive thread zone 10 and the third reverse thread zone 13 is 3a. Wherein a can be any preset value. Taking the lead of the first positive thread zone 8 and the first reverse thread zone 11 closest to the middle as one time, the lead of the second positive thread zone 9 and the second reverse thread zone 12 is set to two times, and the lead of the farthest third positive thread zone 10 and the third reverse thread zone 13 is three times, so that the clamping jaws 7 located in each zone can be adjusted to a designated suitable position, which is convenient for clamping the wontons from the conveyor belt and packing them into boxes.

[0037] Each of the three positive threaded areas and the three negative threaded areas is connected with a screw nut 14, one section of the screw nut 14 is threadedly connected to the screw 4, and the other end is fixedly connected with a sliding mounting plate 15, and the sliding mounting plate 15 is connected to the longitudinal connecting rod 16, and each longitudinal connecting rod 16 is linked with a plurality of connecting sleeves, and the bottom of each connecting sleeve is connected with the clamping jaw 7. Specifically, the screw nut 14 is sleeved with each threaded area, and when the screw 4 rotates, each screw nut 14 located thereon will move along the thread direction, for example, the screw nut 14 located in the positive threaded area will move to the left, and the screw nut 14 located in the negative threaded area will move to the right. Due to the different leads, the distance of each screw nut 14 when moving is also different. One end of the screw nut 14 is connected to the sliding mounting plate 15, and the sliding mounting plate 15 is connected to the clamping jaw 7 through the connecting sleeve. The connecting sleeve can be set to pass through a transverse guide rod as needed, but the transverse guide rod is not required and the normal movement of the clamping jaw 7 is not affected.

[0038] The screw rod 4 is fixed on the mounting frame 19 through bearings 18 at both ends. The mounting frame 19 is provided with a transverse guide rod 20. A plurality of sliding mounting plates 15 are sleeved on the transverse guide rod 20. A fixed mounting plate 21 is fixedly provided in the middle of the transverse guide rod 20. The fixed mounting plate 21 is connected to a longitudinal connecting rod 16. A plurality of connecting sleeves are connected to the longitudinal connecting rod 16. The bottom of each connecting sleeve is connected to a clamping claw 7. The purpose of the transverse guide rod 20 is to sleeve the sliding mounting plate 15, and a fixed mounting plate 21 is fixed in the middle. When the number of clamping claws 7 in each horizontal row is an odd number, when the spacing of the clamping claws 7 in each column is adjusted, the position of the clamping claw 7 in the middle position does not need to be changed, so the clamping claw 7 in the middle position needs to be set to be fixed. When the number of clamping claws 7 in each horizontal row is an even number, there is no need to set the fixed mounting plate 21 in the middle. Both the fixed mounting plate 21 and the sliding mounting plate 15 can be connected to the longitudinal connecting rod 16. The purpose of the longitudinal connecting rod 16 is to set a plurality of clamping claws 7 in a row, which can be designed according to the arrangement of the wontons to be clamped.

[0039] like Figure 5 As shown, the clamp 7 includes a finger cylinder 22 and a first clamp 23 and a second clamp 24 at the output end of the finger cylinder 22. The first clamp 23 and the second clamp 24 are driven by the finger cylinder 22 to open and close. The finger cylinder 22 drives the first clamp 23 and the second clamp 24 to open or close, thereby realizing the action of clamping and putting down. In addition, the finger cylinder 22 can control the action of the cylinder through an electromagnetic valve to realize complex combined actions and remote control, and can also cooperate with controllers such as PLC for automatic control. The specific control part belongs to the prior art in this field, and those skilled in the art know how to realize it. It is not an innovation of this application, so this application will not repeat it.

[0040] like Figure 1 As shown, the output shaft of the first motor 3 is connected to the active synchronous wheel 25, the active synchronous wheel 25 is connected to the driven synchronous wheel 27 through the synchronous belt 26, and the driven synchronous wheel 27 is connected to one end of the screw rod 4. The output shaft of the first motor 3 drives the active synchronous wheel 25 to rotate, the active synchronous wheel 25 drives the driven synchronous wheel 27 to rotate through the synchronous belt 26, and the driven synchronous wheel 27 drives the screw rod 4 to rotate along its central axis.

[0041] like Figure 1 As shown, a mounting plate 28 is provided at the upper end of the fixing plate 1. The mounting plate 28 is used to mount the adjustable-pitch clamp 7 on a mechanical arm or a mechanical structure capable of horizontal and vertical movement, so that the adjustable-pitch clamp 7 can be driven to perform the action of clamping and placing.

[0042] In the description of this 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 a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
