Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather processing, in particular to a device for punching honeycomb holes in artificial leather. Background Art

[0002] The artificial leather honeycomb hole punching device is usually used in the manufacture of artificial leather materials. By punching holes on the surface of the material to form small holes similar to honeycombs, the air permeability and texture of the artificial leather are improved. Such devices are widely used in the fields of synthetic leather, artificial leather, automobile interiors, furniture materials, etc.

[0003] The current punching devices for artificial leather honeycomb holes on the market generally have a fixed drill bit arrangement, which makes it easy to drill the honeycomb holes. However, when the range of the honeycomb holes needs to be reduced, it is necessary to replace the drill bits with different arrangements, which requires stopping the machine and disassembling for replacement, which affects the processing efficiency. For this reason, we propose a punching device for artificial leather honeycomb holes. Utility Model Content

[0004] The utility model aims to provide a device for punching honeycomb holes in artificial leather to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A chassis, wherein first side frames are fixedly connected to both sides of the top of the chassis, mounting frames are fixedly installed on the tops of the two first side frames, and adjustment mechanisms are arranged at the top and bottom of the mounting frames, and the adjustment mechanisms include a lifting cylinder, a fixing ring and a drill rod;

[0008] The two sides of the chassis away from the two first side frames are fixedly connected with second side frames, and the top ends of the two second side frames are provided with locking mechanisms, which include a multi-stage electric cylinder, a locking rod and a locking groove.

[0009] Preferably, three pairs of lifting cylinders are symmetrically arranged on both sides of the top of the mounting frame, and the output shaft ends of the three pairs of lifting cylinders are fixedly installed with fixing rings, and the bottom ends of the three fixing rings are evenly arranged with a plurality of drill rods;

[0010] Preferably, a multi-stage electric cylinder is fixedly installed on the outer side of the top end of the second side frame, a locking rod is fixedly installed on the output shaft end of the multi-stage electric cylinder, and locking grooves are penetrated and formed on both sides of the three fixing rings close to the locking rod;

[0011] Preferably, a plurality of rod grooves are penetrated through the top and bottom ends of the chassis, and the drill rod and the rod grooves are on the same central axis;

[0012] Preferably, the length of the drill rod is twice the depth of the rod groove;

[0013] Preferably, the two first side frames and the two second side frames are arranged in a cross shape.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The device for punching honeycomb holes in artificial leather is used in coordination among a lifting cylinder, a fixing ring, a drill rod and a rod groove. After two lifting cylinders are started, the fixing ring is lifted to raise the drill rod at the bottom end of the fixing ring from the rod groove, so that the honeycomb holes are reduced by one circle from the outer ring. If the range needs to be reduced again, the fixing ring in the middle position can be lifted. In this way, when adjusting the range, there is no need to stop the machine for operation or to replace it manually.

[0016] The device for punching honeycomb holes in artificial leather is used in cooperation with a second side frame, a locking mechanism, a multi-stage electric cylinder and a locking rod. After the two multi-stage electric cylinders are started, the locking rod is retracted from the locking groove, so that the three fixing rings are in an unlocked state, which is convenient for adjustment. When one of the fixing rings is lifted, the locking rod is controlled to fix the remaining two fixing rings, so that the structural stability of the drill rod is higher when drilling.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A device for punching honeycomb holes in artificial leather comprises a chassis 1, first side frames 2 are fixedly connected to both sides of the top of the chassis 1, mounting frames 3 are fixedly installed on the tops of the two first side frames 2, and adjusting mechanisms 4 are arranged at the top and bottom of the mounting frames 3, and the adjusting mechanisms 4 include a lifting cylinder 401, a fixing ring 402 and a drill rod 403; second side frames 5 are fixedly connected to both sides of the chassis 1 away from the two first side frames 2, and locking mechanisms 6 are arranged at the tops of the two second side frames 5, and the locking mechanisms 6 include a multi-stage electric cylinder 601, a locking rod 602 and a locking groove 603, the two first side frames 2 and the two second side frames 5 are arranged in a cross shape, the length of the drill rod 403 is twice the depth of the rod groove 7, and three pairs of lifting cylinders 401 are symmetrically arranged on both sides of the top of the mounting frame 3, the output shaft ends of the three pairs of lifting cylinders 401 are fixedly installed with fixing rings 402, and a plurality of drill rods 403 are arranged at equal arcs at the bottom ends of the three fixing rings 402;

[0026] In this embodiment, when it is necessary to adjust the range of the honeycomb holes, first start a pair of lifting cylinders 401 on the outer side of the mounting frame 3. After the two lifting cylinders 401 are started, the fixing ring 402 is lifted, and the drill rod 403 at the bottom end of the fixing ring 402 is raised from the rod groove 7. In this way, the honeycomb holes are reduced by one circle from the outer ring. If the range needs to be reduced again, the fixing ring 402 in the middle position can be lifted. In this way, when adjusting the range, there is no need to stop the machine for operation or manual replacement.

[0027] like Figure 4 As shown, a multi-stage electric cylinder 601 is fixedly installed on the outer side of the top end of the second side frame 5, a locking rod 602 is fixedly installed on the output shaft end of the multi-stage electric cylinder 601, and locking grooves 603 are penetrated and formed on both sides of the three fixing rings 402 close to the locking rod 602;

[0028] In this embodiment, when unlocking, the multi-stage electric cylinders 601 on the outer sides of the top ends of the two second side frames 5 are started. After the two multi-stage electric cylinders 601 are started, the locking rods 602 are retracted from the locking grooves 603, so that the three fixing rings 402 are in an unlocked state, which makes adjustment convenient. When one of the fixing rings 402 is lifted, the locking rods 602 are controlled to fix the remaining two fixing rings 402, so that the structural stability of the drill rod 403 is higher when drilling.

[0029] like Figure 2 As shown, a plurality of rod grooves 7 are penetrated and opened at the top and bottom of the chassis 1, and the drill rod 403 and the rod groove 7 are on the same central axis;

[0030] In this embodiment, when the drill rod 403 penetrates into the rod groove 7, half of the length of the drill rod 403 will be exposed, which is convenient for drilling holes in artificial leather. In addition, artificial leathers of different thicknesses can be processed by adjusting the exposed length of the rod groove 7, which makes it convenient to drill holes in leathers of different thicknesses.

[0031] Working principle: when it is necessary to adjust the range of the honeycomb hole, first start a pair of lifting cylinders 401 on the outer side of the mounting frame 3. After the two lifting cylinders 401 are started, the fixing ring 402 is lifted, and the drill rod 403 at the bottom end of the fixing ring 402 is raised from the rod groove 7. In this way, the honeycomb hole is reduced by one circle from the outer ring. If the range needs to be reduced again, the fixing ring 402 at the middle position is controlled to be lifted. In this way, when adjusting the range, there is no need to stop the machine for operation or manual replacement; before lifting the fixing ring 402, it is necessary to unlock the fixing ring 402 at this position. When unlocking, start the multi-stage electric cylinders 601 on the outer sides of the top ends of the two second side frames 5. After the two multi-stage electric cylinders 601 are started, the locking rod 602 is retracted from the locking groove 603, so that the three fixing rings 402 are in an unlocked state, which can be conveniently adjusted. When one of the fixing rings 402 is lifted, the locking rod 602 is controlled to fix the remaining two fixing rings 402, so that the structural stability of the drill rod 403 is higher when drilling.
