In addition, the execution module 20, the limiting mechanism 30 and the displacement mechanism 40 provided in this embodiment are simple in structure and light in weight, and can meet the supporting requirement through the single-side supporting effect of the cantilever 10, so as to achieve the variable-pitch effect, thereby meeting the requirements of different use environments.

It should be understood by those skilled in the art that, before and after the pitch change, the distance between any two adjacent actuators of the plurality of actuators and other distances may be equidistant or not equidistant, and may be set according to the needs of the product to be operated, which is not limited specifically.

Referring to fig. 1 and 3, an actuator module 20 is disposed on the cantilever 10, and the actuator module 20 includes a plurality of actuators spaced apart along a first direction. In the present application, the cantilever 10 is configured in a rectangular plate structure, and the first direction is the length direction of the cantilever 10, so as to provide a greater movement range for the actuator. The actuating member is provided with a movable block 23, and the movable block 23 is movably arranged between a first fixed part 32 and a second fixed part 34 of the corresponding fixed block 31; the actuator is driven to synchronously move by the movement of the movable block 23.

The stability of the pushing plate 41 in the moving process is ensured by the embedded cooperation between the sliding groove and the sliding block.

Referring to fig. 3, in some embodiments, one of two adjacent fixed blocks 31 approaches to a reference point of the displacement, the movable block 23 limited in the fixed block 31 is selectively moved between a first position and a second position during the displacement operation, the displacement distance of the fixed block 31 is X, where x=n×d, N is a positive integer, and D is a standard pitch difference;

For convenience of description, when the movable block 23 is attached to the first fixing portion 32 of the corresponding fixed block 31, the position state of the movable block 23 is not changed, that is, the first position of the movable block 23 during the distance changing operation; the movable block 23 moves between the first fixing portion 32 and the second fixing portion 34 of the corresponding fixed block 23 during the distance changing operation, so that the movable block is located to be attached to the second fixing portion 34 of the corresponding fixed block 31 after the distance changing operation, and the position state of the movable block 23 after the distance changing operation is the second position of the movable block 23 during the distance changing operation.

In connection with fig. 1, the displacement reference point described in the foregoing may be any defined position in the actual production operation, and the present embodiment is exemplified by taking the middle of the cantilever 10 in the first direction as the displacement reference point (which may also be understood as the starting fixed point of the pushing member for realizing displacement, which is generally no solid member, but just referred to), and one of the adjacent two fixed blocks 31 in the plurality of fixed blocks 31 disposed at intervals along the first direction has one fixed block 31 closer to the displacement reference point (i.e., the fixed block 31 near the middle of the cantilever), and one fixed block 31 farther from the displacement reference point (i.e., the fixed block 31 far from the middle of the cantilever).

Likewise, the standard pitch difference described in the foregoing is: the distance between the first position and the second position of the movable block 23 closest to the displacement reference point is the distance between the first position and the second position before and after the displacement reference point, and N in the displacement distance is the ordinal number of each movable block 23 with the displacement reference point as the origin. The above description is that the embodiment realizes the embodiment that each executing piece is equidistant before and after the distance change, and the distance between the adjacent executing pieces after the distance change is increased by one standard distance difference.

Through two groups of displacement mechanisms 40, two groups of execution modules 20 and limiting mechanisms 30 matched with the displacement mechanisms, a plurality of products can be driven to perform variable-distance movement through a plurality of execution pieces, so that the working efficiency is improved.

Optionally, the plurality of executing members may be movably disposed on the cantilever 10, and similarly, the plurality of executing members may further include a fixed executing member 21 and a plurality of movable executing members 22, where the fixed executing member 21 is fixedly disposed on the cantilever 10, the movable block 23 is disposed on the movable executing member 22, and the fixed executing member 21 is used as a variable-pitch reference point, and the movement of the plurality of movable executing members 22 may also implement variable-pitch material taking of each executing member, so as to meet requirements of different use environments.

Similarly, the four movable executing elements 22 can perform the distance-changing adjustment through the two sets of displacement mechanisms 40 and the limit mechanisms 30 matched with the two sets of displacement mechanisms, at this time, the fixed executing element 21 is fixed on the cantilever 10 and is positioned at the middle position of the plurality of executing elements in the first direction, that is, the two movable executing elements 22 are respectively arranged at two sides of the fixed executing element 21 in the first direction, the two movable executing elements 22 are one set of executing elements, one set of the limit mechanisms 30 and one set of the displacement mechanisms 40 are used for realizing the distance-changing operation of one set of executing elements relative to the fixed executing element 21, and the other set of the limit mechanisms 30 and the other set of the displacement mechanisms 40 are used for realizing the distance-changing operation of the other set of executing elements relative to the fixed executing element 21; therefore, the two sets of limiting mechanisms 30 are symmetrically arranged on the cantilever 10 relative to the fixed executing piece 21, and the two sets of displacement mechanisms 40 are also symmetrically arranged on the cantilever 10 relative to the fixed executing piece 21.

Referring to fig. 1 to 4, in some embodiments, the movable block 23 and the movable executing member 22 are respectively located at the upper and lower sides of the cantilever 10, the movable block 23 may be assembled and connected with the movable executing member 22, the movable block 23 passes through a slot on the cantilever 10 and is connected with the fixed block 31, and the fixed block 31 is assembled and connected with the cantilever 10, so that stable movement of the movable executing member 22 can be ensured through up-down structural arrangement, and interference influence possibly occurring in the cantilever 10 during movement of the movable executing member 22 can be avoided. The movable block 23 penetrates the cantilever 10 to be movably disposed between the first fixing portion 32 and the second fixing portion 34, and illustratively, in this application, the movable actuator 22 is disposed below the cantilever 10, the movable block 23 is disposed above the cantilever 10, the movable block 23 is disposed at a side of the movable actuator 22 facing the cantilever 10, and penetrates the cantilever 10 along a height direction of the cantilever 10, so that the movable block 23 is ensured to be movably assembled between the first fixing portion 32 and the second fixing portion 34.

Illustratively, the fixed block 31 may be fixedly disposed on the cantilever 10, including welding the fixed block 31 to the cantilever 10, etc.; likewise, the fixing block 31 may be detachably disposed on the cantilever 10, including that the fixing block 31 is connected to the cantilever 10 through a bolt thread or that the fixing block 31 is fastened to the cantilever 10 through a buckle, so as to facilitate replacement of the fixing block 31 and maintenance. At the same time, the cantilever 10 can be provided with the fixing blocks 31 with different distances between the first fixing part 32 and the second fixing part 34, so as to meet different application environments.

Likewise, the movable block 23 may be fixedly disposed on the movable actuator 22, including the movable block 23 being welded to the movable actuator 22, etc.; likewise, the movable block 23 may be detachably disposed on the movable executing member 22, including that the movable block 23 is connected to the movable executing member 22 by a bolt thread or that the movable block 23 is fastened to the movable executing member 22 by a fastener, so as to facilitate replacement of the movable block 23 and maintenance. At the same time, the movable executing piece 22 can be replaced by the movable blocks 23 with different lengths in the first direction so as to meet different application environments.

Referring to fig. 3 and 4, the cantilever 10 is further provided with a guide rail 11 extending along the first direction, and a plurality of movable actuators 22 are slidably disposed on the guide rail 11; the stability of the movement of the movable actuator 22 is ensured by the arrangement of the guide rail 11. Alternatively, the guide rail 11 is connected to a middle position of the movable actuator 22 in a second direction, which is perpendicular to the first direction. In order to avoid interference between the arrangement of the guide rail 11 and the movable block 23, the movable block 23 is connected to a side wall surface of the movable actuator 22.

Referring to fig. 5, a side of the first fixing portion 32 facing the second fixing portion 34 is a first fixing surface 33, and a side of the second fixing portion 34 facing the first fixing portion 32 is a second fixing surface 35; the side of the movable block 23 facing the first fixing portion 32 is a first movable surface 24, and the side of the movable block 23 facing the second fixing portion 34 is a second movable surface 25. When the first movable surface 24 of the movable block 23 is attached to the first fixed surface 33 of the first fixed portion 32 of the corresponding fixed block 31, the plurality of executing pieces are uniformly distributed at intervals; when the second movable surface 25 of the movable block 23 is attached to the second fixing surface 35 of the second fixing portion 34 of the corresponding fixing block 31, the plurality of actuators are distributed in a variable distance.

Optionally, the pushing plate 41 is provided with a plurality of pushing portions 43, the pushing surface 44 of each pushing portion 43 is used for correspondingly matching with the first movable surface 24 of each movable block 23, and the distance between two adjacent pushing surfaces 44 gradually increases in the direction away from the displacement datum point, so that when the pushing surfaces 44 move towards one side of the adjacent first movable surface 24, the plurality of movable blocks 23 can be pushed to move by the pushing plate 41 in sequence, and the displacement of the movable executing piece 22 is realized. At this time, it is ensured that the distance between the first fixed portion 32 and the second fixed portion 34 can satisfy the moving distance of the movable block 23, avoiding the movable block 23 being restricted by the fixed block 31 to prevent the movement of the push plate 41.

Specifically, the first fixing portion 32 and the second fixing portion 34 of each fixing block 31 are at a pitch-varying distance therebetween, and the pitch-varying distances of each fixing block 31 gradually increase in a direction away from the pitch-varying reference point in the first direction; when the distance between the adjacent actuators needs to be adjusted, the pushing plate 41 moves in a direction away from the displacement datum point, so that each movable block 23 is pushed in turn, and the movement of the movable blocks 23 drives the synchronous movement of the actuators to realize displacement.

Referring to fig. 1 and 5, the distance between two adjacent second fixing surfaces 35 is generally equal to the distance between two pushing surfaces 44 corresponding to the two adjacent second fixing surfaces, so that the movable block 23 is pushed by the pushing plate 41 in turn, but the second movable surface 25 of the movable block 23 may simultaneously abut against the second fixing portion 34 of the fixed block 31, so as to ensure the reliability of the position of the movable block 23 after the distance change.

Referring to fig. 1 to 3, the pushing plate 41 is positioned above the fixed block 31, and the movable block 23 is higher than the fixed block 31 to be engaged with the pushing part 43. By arranging the pushing plate 41 above the fixed block 31, the pushing plate 41 can be ensured not to interfere with the position of the fixed block 31 in the moving process, and the pushing effect of the pushing plate 41 on the movable block 23 can be ensured.

Alternatively, the pushing plate 41 and the fixing block 31 are disposed at intervals in a second direction perpendicular to the first direction, and both the first direction and the second direction are perpendicular to the height direction of the cantilever 10.

Meanwhile, the movable block 23 can be limited in the second direction by the pushing plate 41 and the fixed block 31, so that the stability of the movement of the movable block 23 is further improved.

Referring to fig. 1 and 5, in the embodiment provided in the present application, the pitch shifting assembly further includes a reset mechanism 50, where the reset mechanism 50 includes a pin 51 and an elastic member 52, where two ends of the pin 51 are respectively connected with the first fixing portion 32 and the second fixing portion 34, and the pin 51 penetrates through the movable block 23 along the first direction, or alternatively, an inner end of the pin 51 is screwed and fixed to the movable block 23, and a large diameter end of an outer end of the pin 51 penetrates through the second fixing portion 34 to form a movable end. Specifically, the pin 51 may be inserted into the fixed block 31, or the pin 51 may be fixedly disposed on the fixed block 31. The elastic member 52 is disposed between the movable block 23 and the second fixed portion 34, so that the movable block 23 is attached to the first fixed portion 32. The arrangement of the elastic member 52 can ensure that the first movable surface 24 of the movable block 23 can be attached to the first fixed surface 33 of the first fixed block 31 in the initial state, and the first state is the same. Illustratively, the resilient member 52 comprises rubber or a spring, etc., and in this application the resilient member 52 is a spring.

In the second state, the pushing part 43 drives the movable block 23 to move towards the second fixed part 34, and the plurality of executing pieces are sequentially pushed, so that the variable-pitch distribution is realized. Therefore, in the second state, the driving assembly 42 drives the pushing plate 41 to move in the opposite direction of the first direction so as to drive the movable block 23 to move towards the side close to the second fixed portion 34, the pushing portion 43 abuts against the first movable surface 24 of the movable block 23, and the elastic member 52 abuts against the second movable surface 25 of the movable block 23, so that the force balance of the movable block 23 in the first direction is realized, and the stable movement of the movable block 23 is ensured.

Optionally, the pin shaft 51 penetrates through the second fixing portion 34 along the first direction and protrudes out of the second fixing portion 34, a baffle is arranged at one end of the pin shaft 51 away from the first fixing portion 32, and two ends of the elastic piece 52 are respectively abutted with the baffle and the second movable surface 25; the pin shaft 51 protruding out of the second fixing portion 34 provides a place for compressing the elastic member 52, so that the second movable surface 25 of the movable block 23 can be attached to the second fixing surface 35 of the second fixing portion 34, and the maximum movable range of the movable block 23 is ensured.

Similarly, the pushing plate 41 may further be provided with a plurality of second pushing portions, where the plurality of second limiting portions are configured to be matched with the plurality of pushing portions 43 at intervals, and the second limiting portions are configured to be arranged at intervals with the pushing portions 43 in the first direction, and one side of the second limiting portions facing the pushing portions 43 is configured to abut against the second movable surface 25 of the movable block 23; the pushing plate 41 moves in the opposite direction of the first direction, and the pushing part 43 pushes the movable block 23 to move toward one side of the second fixed part 34; when the pushing plate 41 moves in the forward direction of the first direction, the second limiting portion can push the movable block 23 to move towards one side of the first fixed portion 32.

The movable block 23 is elastically biased by the elastic member 52, so that the first movable surface 24 of the movable block 23 is attached to the first fixed surface 33 of the first fixed portion 32, and at this time, the actuators are disposed at equal intervals. When each movable actuator 22 needs to change the distance, the driving component 42 drives the pushing plate 41 to move in the direction away from the distance changing reference point, and during the movement process of the pushing plate 41, each movable block 23 is pushed to move at intervals in sequence, so that the distance between a plurality of movable actuators 22 is changed.
