Description

Technical Field

[0001] The present application relates to the technical field of sponge processing equipment, and in particular to a sponge cutting and fixing device. Background Art

[0002] Sponge is a porous material with good water absorption and can be used to clean objects. The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In the process of sponge production and processing, the sponge needs to be cut.

[0003] When the sponge is cut, in order to ensure the stability of the cutting process, the sponge generally needs to be fixed. Common square sponges generally adopt double-reference fixation, that is, two driving mechanisms respectively drive the clamping plates close to the adjacent sides of the sponge to achieve clamping and fixation. The two clamping directions are perpendicular to each other and clamped with the sponge as the center; the above-mentioned conventional clamping method generally requires at least two clamping driving mechanisms to achieve clamping in two directions. The two clamping driving mechanisms are independent of each other, so the linkage of the clamping action is not high. In this regard, this scheme aims to make further improvements on this basis, so as to improve the linkage of the clamping action under the premise of reducing the driving mechanism.

[0043] Example

[0044] When the sponge is cut, in order to ensure the stability of the cutting process, the sponge generally needs to be fixed. Common square sponges generally adopt double-reference fixation, that is, two driving mechanisms respectively drive the clamping plates close to the adjacent two sides of the sponge to achieve clamping and fixation. The two clamping directions are perpendicular to each other and clamped with the sponge as the center; the above conventional clamping method generally requires at least two clamping driving mechanisms to achieve clamping in two directions. The two clamping driving mechanisms are independent of each other, so the linkage of the clamping action is not high. In this regard, this scheme aims to make further improvements on this basis, so as to improve the linkage of the clamping action under the premise of reducing the driving mechanism; in order to solve the above technical problems, this embodiment provides the following technical solutions:

[0045] For details, see Figure 1-6 , this embodiment provides a sponge cutting and fixing device, including a workbench 10, a driving mechanism 30 and a linkage mechanism;

[0046] Furthermore, a first positioning plate 23, a second positioning plate 24, a first clamping plate 21 and a second clamping plate 22 are provided on the workbench 10; the first positioning plate 23 is arranged opposite to the first clamping plate 21, and the second positioning plate 24 is arranged opposite to the second clamping plate 22;

[0049] Specifically, the linkage mechanism includes a first link 41 connected to the driving mechanism 30, a linkage assembly provided at one end of the first link 41 away from the driving mechanism 30, and a second link 42 connected to the first link 41, the second link 42 is connected to the first clamping plate 21, and the linkage assembly connects the first link 41 and the second clamping plate 22 and is suitable for driving the second clamping plate 22 to move along the second direction;

[0050] Wherein, the first direction and the second direction are perpendicular to each other;

[0051] In the above scheme, the staff places the sponge to be cut on the workbench 10, so that the two sides of the sponge are respectively against the first positioning plate 23 and the second positioning plate 24 to achieve preliminary positioning, and then starts the driving mechanism 30, the driving mechanism 30 drives the first connecting rod 41 to move along the first direction, and then drives the second connecting rod 42 to move along the first direction, the second connecting rod 42 is connected to the first clamping plate 21, so the first clamping plate 21 moves along the first direction and approaches the first positioning plate 23, the first clamping plate 21 and the first positioning plate 23 realize the clamping and fixing of the sponge in the first direction, when the first connecting rod 41 moves along the first direction, it passes The linkage assembly drives the second clamping plate 22 to move along the second direction to approach the second positioning plate 24, and the second clamping plate 22 cooperates with the second positioning plate 24 to clamp the sponge in the second direction, and finally achieves clamping and fixation in the first direction and the second direction to ensure the stability of the cutting process; in this solution, it only adopts one driving mechanism 30, and the driving mechanism 30 can simultaneously realize the synchronous action of the first clamping plate 21 and the second clamping plate 22 through the cooperation of the first connecting rod 41, the second connecting rod 42 and the linkage assembly, which not only effectively reduces the number of driving mechanisms 30, but also makes the action consistency of the first clamping plate 21 and the second clamping plate 22 better.

[0052] In one embodiment, the sponge cutting may be performed by laser cutting.

[0053] For details, see Figure 2 The linkage assembly includes a first housing 431, a sliding housing 432 and a sliding block 433; the first housing 431 is formed with a housing cavity suitable for accommodating the sliding housing 432, the sliding housing 432 is suitable for sliding along a first direction and is disposed in the first housing 431 and connected to the first connecting rod 41; the side wall of the sliding block 433 is formed with a convex column 4331;

[0054] Furthermore, a first limiting groove 4311 is formed on the side wall of the first housing 431 along the second direction, a guide groove 434 is formed on the side wall of the sliding housing 432, and the protruding column 4331 passes through the guide groove 434 and the first limiting groove 4311 in sequence;

[0055] Specifically, when the sliding shell 432 moves along the first direction, the boss 4331 cooperates with the first limiting groove 4311 and the guide groove 434 to drive the sliding block 433 to move along the second direction, and the sliding block 433 passes through the first shell 431 along the second direction and connects with the second clamping plate 22;

[0056] Furthermore, the first housing 431 is connected to the second clamping plate 22 via a third connecting rod 44;

[0057] In the above scheme, when the first connecting rod 41 moves along the first direction, it drives the sliding shell 432 to move along the first direction. The sliding block 433 located in the sliding shell 432 has its protruding column 4331 pass through the guide groove 434 on the sliding shell 432 and the limiting groove 4311 on the first outer shell 431 in sequence, so it is guided and limited by the guide groove 434 and the limiting groove 4311 at the same time, and the extension direction of the limiting groove 4311 is the second direction. Therefore, when the sliding shell 432 moves along the first direction, the sliding block 433 will move along the second direction. The sliding block 433 and the second clamping plate 22 are connected by the third connecting rod 44. Therefore, when the sliding block 433 moves along the second direction, it will simultaneously drive the second clamping plate 22 to move along the second direction through the third connecting rod, thereby realizing the first clamping plate 21 moving along the first direction and the second clamping plate 22 moving along the second direction at the same time.

[0058] For details, see Figure 2 , the guide groove 434 includes a first straight line segment 4341, an oblique line segment 4342 and a second straight line segment 4343 in sequence along the second direction;

[0059] In the above scheme, the sliding shell 432 moves along the first direction, and the boss 4331 moves before the first straight line segment 4341. At this time, it can be understood that the second clamping plate 22 has not moved. When the boss 4331 further enters the oblique line segment 4342, it will drive the boss 4331 and the sliding block 433 to move along the second direction. When the boss 4331 further enters the second straight line segment 4343, the second clamping plate 22 enters a non-moving state again.

[0060] In some embodiments, the first straight line segment 4341 and the second straight line segment 4343 may not be provided, and only the oblique line segment 4342 may be provided.

[0061] For details, see Figure 3 A first through slot 11 is formed on the workbench 10 along a first direction, and a second through slot 12 is formed along a second direction;

[0062] Furthermore, the second connecting rod 42 is adapted to pass through the first through slot 11 and connect to the first clamping plate 21 , and the third connecting rod 44 is adapted to pass through the second through slot 12 and connect to the second clamping plate 22 ;

[0063] In the above solution, the first through slot 11 provides an escape position for the first connecting rod 41 , and the second through slot 12 provides an escape position for the third connecting rod 44 .

[0064] Specifically, a first through hole 4312 suitable for the first connecting rod 41 to pass through is defined on one side of the first housing 431 close to the first connecting rod 41 .

[0065] Specifically, the second connecting rod 42 includes an L-shaped portion 421 connected to the first connecting rod 41 and a strip portion 422 connected to the L-shaped portion 421 and away from the first connecting rod 41 , and the strip portion 422 is connected to the first clamping plate 21 .

[0066] Specifically, the first positioning plate 23 and the second positioning plate 24 are detachably disposed on the workbench 10;

[0067] In the above scheme, the first positioning plate 23 and the second positioning plate 24 can be detachably arranged on the workbench 10, that is, in actual application, the staff can adjust the positions of the first positioning plate 23 and the second positioning plate 24 according to the actual size of the sponge, and finally adapt to sponges of different sizes to improve the applicability of the fixing device.

[0068] For details, see Figure 6 A first waist-shaped hole 13 is provided on the workbench 10 along the first direction, and a second waist-shaped hole 13 is provided along the second direction;

[0069] Furthermore, threaded holes 231 are provided at the bottom of the first positioning plate 23 and the second positioning plate 24;

[0070] Furthermore, it also includes a locking bolt 232 adapted to the threaded hole 231, and the locking bolt 232 is suitable for passing through the first waist-shaped hole 13 to fix the first positioning plate 23, and passing through the second waist-shaped hole 13 to fix the second positioning plate 24;

[0071] In the above implementation process, taking the first positioning plate 23 as an example, when the position of the first positioning plate 23 needs to be adjusted, the locking bolt 232 is first loosened to make the first positioning plate 23 movable. When it is adjusted to a suitable position, the locking bolt 232 is tightened to fix the first positioning plate 23, and the second positioning plate 24 is the same. The combination of the locking bolt 232 and the waist-shaped hole makes the adjustment simple and quick, thereby improving the adjustment efficiency of the staff.
