Description

Technical Field

[0001] The utility model relates to the technical field of woven bag processing, and particularly relates to an auxiliary device for woven bag processing. Background Art

[0002] A woven bag is a bag made of plastic or fiber materials, usually used for packaging, transportation and storage of various items. At the same time, due to its internal grid-like texture structure, usually made of interwoven plastic tapes or fiber threads, it has strong tensile strength and durability.

[0003] In the prior art, people often need to cut the extruded plastic film into embryo filaments with a blade and stretch it into flat filaments at the oven.

[0004] However, in the actual use process, when people cut the plastic film with a cutter, since the cutting edge is in contact with the plastic film, it will be continuously affected by friction. At the same time, since it is directly exposed to the air for a long time, it will need to be maintained after being used for a period of time. And when the existing cutter is maintained, it often needs to be temporarily shut down, so as to reduce the risk of the cutter hurting the maintenance personnel during maintenance. However, the shutdown operation of the equipment will also affect the processing efficiency of the woven bag. In view of this, we propose an auxiliary device for woven bag processing. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an auxiliary device for woven bag processing, which solves the problems mentioned in the above background art.

[0006] To achieve the above purpose, an auxiliary device for woven bag processing proposed by the utility model includes a workbench, a rotating shaft is rotatably connected to the inner surface of the workbench, a quick-release cutting device is arranged on the outer arc surface of the rotating shaft, and auxiliary positioning devices are arranged at the front and rear ends of the rotating shaft;

[0007] The quick-release cutting device includes a mounting block, a slider is slidably connected to the inner surface of the mounting block, a push block is fixedly connected to the outer surface of the slider, an extrusion block is fixedly connected to the lower surface of the slider, a positioning block is slidably connected to the lower end of the inner surface of the mounting block, and a contact block is fixedly connected to the upper surface of the positioning block.

[0008] Preferably, the auxiliary positioning device includes a front connection block, a plug rod is slidably connected to the inner surface of the front connection block, a ring block is fixedly connected to the outer arc surface of the plug rod, the outer surface of the front connection block is fixedly connected to the rotating shaft, a rear connection block is fixedly connected to the end of the rotating shaft away from the front connection block, and an auxiliary block is slidably connected to the inner surface of the rear connection block.

[0009] Preferably, a plurality of groups of penetrating rectangular through holes are provided on the upper surface of the workbench, penetrating through holes are provided at both the front and rear ends of the workbench, and arc-shaped grooves are provided at both the front and rear ends of the workbench.

[0010] Preferably, a plurality of groups of T-shaped grooves are provided on the outer arc surface of the rotating shaft, and a cutter is fixedly connected to the upper surface of the mounting block.

[0011] Preferably, a through rectangular sliding groove is provided on the mounting block near the sliding block, the sliding block is configured as an L-shape as a whole, and the lower surface of the extrusion block is configured as an inclined surface.

[0012] Preferably, two groups of positioning blocks are provided, and the two groups of positioning blocks are symmetrically distributed with the center line of the mounting block as the symmetry axis, the two groups of positioning blocks are elastically connected by springs, and the upper surface of the contact block is set as an inclined surface.

[0013] Preferably, the inner surface of the front connecting block is provided with a plurality of groups of through holes, the inner surface of the ring block is provided with a through hole at the center, and the outer surface of the ring block is elastically connected to the front connecting block via a spring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) When it is necessary to inspect and repair one of the groups of cutters outside the rotating shaft separately, the slide block can be driven to move synchronously by pushing the push block. At this time, the extrusion block on the lower surface of the slide block will push the two groups of positioning blocks on both sides to move toward each other through the contact between the inclined surface of its lower surface and the contact block. At this time, the positioning block will not limit the position of the mounting block, so that people can remove the mounting block and the cutter thereon for inspection and repair. During the installation process, it is only necessary to repeat the above operation to synchronously install the cutter and the mounting block to the outer arc surface of the rotating shaft, thereby improving people's efficiency in inspecting the cutting knife.

[0017] (2) When the woven bag processing auxiliary device is in use, the cutter will continuously cut the plastic film being transported into small strips. When the cutter needs to be repaired after being used for a long time, the plug rod can be pulled outward to keep it away from the groove at the front end of the workbench and release the angle limit of the front connecting block. At this time, the rotating shaft and the rear connecting block can be rotated at the same time by rotating the front connecting block. Similarly, the quick-release cutting device on the outer arc surface of the rotating shaft will also rotate accordingly, so that the spare knife will rotate and rise, and the common knife will move to the lower end of the workbench due to the rotation of the rotating shaft, so as to facilitate people to repair it. During the rotation process, the spare knife will take over the common knife to cut the plastic film, thereby improving the processing efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a woven bag processing auxiliary device, comprising a workbench 1, the inner surface of the workbench 1 is rotatably connected with a rotating shaft 4, a quick-release cutting device 2 is arranged at the outer arc surface of the rotating shaft 4, and auxiliary positioning devices 3 are arranged at the front and rear ends of the rotating shaft 4;

[0030] The quick-release cutting device 2 includes a mounting block 203, the inner surface of the mounting block 203 is slidably connected to a slider 201, the outer surface of the slider 201 is fixedly connected to a push block 202, the lower surface of the slider 201 is fixedly connected to an extrusion block 204, the lower end of the inner surface of the mounting block 203 is slidably connected to a positioning block 206, and the upper surface of the positioning block 206 is fixedly connected to a contact block 205.

[0031] Specifically, the upper surface of the workbench 1 is provided with a plurality of rectangular through holes, so that when the rotating shaft 4 drives the quick-release cutting device 2 to rotate, the workbench 1 is not easy to interfere with its movement. The front and rear ends of the workbench 1 are provided with through holes, so that the rotating shaft 4 can be located inside it. The front and rear ends of the workbench 1 are provided with arc grooves, so that the insertion rod 302 and the auxiliary block 305 can limit the angle of the rotating shaft 4 by inserting the grooves. The outer arc surface of the rotating shaft 4 is provided with a plurality of T-shaped grooves, so that the mounting block 203 can be located therein. A cutter is fixedly connected to the upper surface of the mounting block 203, and a mounting block 203 is provided near the slider 201. The rectangular slide groove runs through, so that people can push the slider 201 to move through the push block 202 here. The slider 201 is set to be L-shaped as a whole, and the lower surface of the extrusion block 204 is set to be an inclined surface. Therefore, when it contacts with the contact block 205, it can push the contact block 205 and the positioning block 206 at its lower end to move. There are two groups of positioning blocks 206, and the two groups of positioning blocks 206 are symmetrically distributed with the center line of the mounting block 203 as the symmetry axis. The two groups of positioning blocks 206 are elastically connected by springs, so that the positioning blocks 206 on both sides can be driven by the spring elastic force to move to both sides of the mounting block 203 when not subject to external force. The upper surface of the contact block 205 is set to be an inclined surface.

[0032] In the embodiment of the utility model, the auxiliary positioning device 3 includes a front connecting block 303, the inner surface of the front connecting block 303 is slidably connected with the insertion rod 302, the outer arc surface of the insertion rod 302 is fixedly connected with the ring block 301, the outer surface of the front connecting block 303 is fixedly connected to the rotating shaft 4, the end of the rotating shaft 4 away from the front connecting block 303 is fixedly connected with the rear connecting block 304, and the inner surface of the rear connecting block 304 is slidably connected with the auxiliary block 305.

[0033] The outer surface of the ring block 301 is elastically connected to the front connecting block 303 by a spring, so that when people release the plug rod 302, the spring can push the ring block 301 and the plug rod 302 to move toward the groove on the outer surface of the workbench 1 due to its own elastic force. The outer arc surface of the ring block 301 is slidably connected to the front connecting block 303. The outer surface of the auxiliary block 305 is elastically connected to the rear connecting block 304 by a spring, so that the spring can always give the auxiliary block 305 a force to move toward the workbench 1, so that it can be embedded in the rear end groove of the workbench 1 and assist the plug rod 302 to limit the position of the rotating shaft 4. The inner surface of the rear connecting block 304 is provided with a plurality of arc-shaped grooves, so that the auxiliary block 305 can be located inside it.

[0034] When working (or in use), the cutter will continuously cut the plastic film being transported into small strips. When the cutter needs to be repaired after being used for a long time, the insertion rod 302 can be pulled outward to keep it away from the groove at the front end of the workbench 1, and the angle limit of the front connecting block 303 can be released. At this time, the rotating shaft 4 and the rear connecting block 304 can be rotated at the same time by rotating the front connecting block 303. Similarly, the quick-release cutting device 2 on the outer arc surface of the rotating shaft 4 will also rotate accordingly, so that the spare knife will rotate and rise, and the common knife will move to the lower end of the workbench 1 due to the rotation of the rotating shaft 4, so as to facilitate people to repair it, and during the rotation process, the spare knife will take over the common knife to cut the plastic film, thereby improving the processing efficiency of the equipment.

[0035] At the same time, when the device needs to inspect one of the groups of cutters outside the rotating shaft 4 separately, the slider 201 can be driven to move synchronously by pushing the push block 202. At this time, the extrusion block 204 on the lower surface of the slider 201 will push the two groups of positioning blocks 206 on both sides to move toward each other through the contact between the inclined surface of its lower surface and the contact block 205 during movement. At this time, the positioning block 206 will not limit the position of the mounting block 203, so that people can remove the mounting block 203 and the cutter thereon for inspection. During the installation process, it is only necessary to repeat the above operation to synchronously install the cutter and the mounting block 203 to the outer arc surface of the rotating shaft 4, thereby improving people's efficiency in inspecting the cutting knife.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
