Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, specifically a ton bag cutting device. Background Technology

[0002] The production of ton bags requires the cutting and sewing of raw materials. However, with existing cutting equipment, wrinkles may appear on the surface of the fabric during the cutting process, and the cutting often becomes skewed, resulting in the cut surface becoming tilted or curved.

[0003] In the prior art, patent announcement number CN218909316U discloses a ton bag fabric cutting machine, including a base plate, a conveying frame on the top surface of the base plate, a moving groove on the top surface of the conveying frame, a mounting bracket on the top surface of the conveying frame, and the mounting bracket being movably connected to the moving groove. A moving screw is provided in the moving groove and is movably connected to the moving groove and threadedly connected to the mounting bracket. A moving motor is provided on the side of the mounting bracket, and the output end of the moving motor is connected to one end of the moving screw. A first lifting cylinder and a second lifting cylinder are provided on the top surface of the mounting bracket. The output ends of the first lifting cylinder and the second lifting cylinder are respectively provided with a scraper and a cutting blade.

[0004] The aforementioned device utilizes two cylinders to drive the scraper and blade downwards, respectively, to smooth and cut the fabric. During the material cutting process, some small debris is inevitably generated. As the cutting operation continues, these debris gradually accumulate on the positioning plate, forming a thick layer. This accumulation not only interferes with the accuracy of the cutting process but may also damage the cutting equipment. Utility Model Content

[0005] The purpose of this invention is to provide a ton bag cutting device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ton bag cutting device, including a mounting bracket, a retainer fixedly mounted on the mounting bracket, a second sliding groove formed in the middle of the mounting bracket, a first sliding groove formed on one side of the second sliding groove, and a third sliding groove formed on the other side of the second sliding groove. A cutting mechanism is mounted on the mounting bracket, the cutting mechanism including a scraper seat movably mounted in the first sliding groove and a blade seat movably mounted in the third sliding groove, a blade body fixedly mounted on the blade seat, a scraper body fixedly mounted on the scraper seat, and a dust extraction mechanism rotatably mounted in the second sliding groove.

[0007] Preferably, the cutting mechanism further includes a cylinder fixedly mounted on a retainer, a lifting beam fixedly mounted at the output end of the cylinder, one end of the lifting beam fixedly mounted on a blade holder, the lifting beam slidably mounted on a scraper holder, a movable sliding groove provided on the scraper holder, a spring provided in the sliding groove, and a silicone head provided at the bottom of the scraper body.

[0008] Preferably, a guide rod is provided at the middle position of the sliding groove, and the spring is constrained in the sliding groove by the guide rod. One end of the spring is connected to the bottom of the sliding groove, and the other end of the spring is connected to the lifting beam.

[0009] Preferably, the other end of the lifting beam is slidably mounted on the scraper seat via a sliding groove, the scraper body is movably mounted in the first sliding groove via the scraper seat, the blade body is slidably mounted in the third sliding groove via the blade seat, and the lower end of the scraper body is slightly lower than the lower end of the blade body.

[0010] Preferably, the dust extraction mechanism includes a dust extraction nozzle that is movably and slidably installed in the second slide groove, a dust extraction pipe that is fixedly installed on the dust extraction nozzle, a driving rack that is fixedly installed on one side of the dust extraction nozzle, a driven rack that is fixedly installed on the side wall of the scraper body, a transmission gear that is provided between the driven rack and the driving rack, and a movable shaft that is fixedly installed on the transmission gear.

[0011] Preferably, the mounting bracket is equipped with a bearing, and the movable shaft is rotatably mounted in the mounting bracket via the bearing.

[0012] Preferably, the dust extraction nozzle is slidably installed in the mounting bracket via the second sliding groove, and the transmission gear is rotatably installed between the driving rack and the driven rack via a movable shaft, and the transmission gear meshes with the driving rack and the driven rack respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, during the extension of the cylinder, it drives the lifting beam to move downwards. Subsequently, the downward movement of the lifting beam causes the blade body and scraper body to move downwards synchronously. Since the lower end of the scraper body is slightly lower than the blade body, the scraper body will contact the fabric surface first during the downward movement of the blade body and scraper body. This contact action causes the fabric to be pulled and smoothed under the action of the scraper body. After the fabric is successfully smoothed, the extension action of the cylinder can be further controlled. When the cylinder continues to extend, one end of the lifting beam will drive the blade body to move downwards, while the other end of the lifting beam will slide down along the sliding groove. Through this series of actions, the smoothing and cutting of the fabric is achieved using a set of cylinders.

[0015] 2. In this application, during the cylinder's retraction process, the drive scraper body moves upward. Subsequently, the upward movement of the scraper body causes the driven rack to move upward, which in turn causes the transmission gear to rotate. The rotation of the transmission gear causes the driving rack to move downward, ultimately causing the dust extraction nozzle to move downward. When the dust extraction nozzle reaches the cutting position, it can effectively absorb the debris generated during the cutting process and quickly remove these debris. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a ton bag cutting device, including a mounting bracket 1, a retainer 2 fixedly mounted on the mounting bracket 1, a second slide groove 4 opened in the middle of the mounting bracket 1, a first slide groove 3 opened on one side of the second slide groove 4, a third slide groove 5 opened on the other side of the second slide groove 4, a cutting mechanism 6 mounted on the mounting bracket 1, and a dust extraction mechanism 7 rotatably mounted in the second slide groove 4. Through the cooperation of the cutting mechanism 6 and the dust extraction mechanism 7, the debris generated during cutting can be quickly collected.

[0023] like Figure 2 and Figure 3 As shown, the cutting mechanism 6 includes a scraper seat 607 movably installed in the first slide groove 3 and a blade seat 603 movably installed in the third slide groove 5. A blade body 604 is fixedly installed on the blade seat 603, and a scraper body 605 is fixedly installed on the scraper seat 607. The cutting mechanism 6 also includes a cylinder 601 fixedly installed on the retainer 2. A lifting beam 602 is fixedly installed at the output end of the cylinder 601. One end of the lifting beam 602 is fixedly installed on the blade seat 603, and the lifting beam 602 is slidably installed on the scraper seat 607. A movable sliding groove 608 is provided on the scraper seat 607. A spring 609 is provided in the sliding groove 608. A silicone head 606 is provided at the bottom of the scraper body 605. A guide rod is provided in the middle of the sliding groove 608. The spring 609 is restricted in the sliding groove 608 by the guide rod. One end of the spring 609 is connected to the bottom of the sliding groove 608, and the other end of the spring 609 is connected to the lifting beam 602.

[0024] Specifically, once cylinder 601 is fully extended, it drives the lifting beam 602 to move downwards. As the lifting beam 602 descends, the blade body 604 and scraper body 605 also move downwards. Because the lower end of scraper body 605 is designed to be slightly lower than the lower end of blade body 604, during the downward movement of blade body 604 and scraper body 605 together, scraper body 605 will first contact the surface of the fabric. In this way, scraper body 605 can smooth the fabric. After the fabric is smoothed, cylinder 601 can be further controlled to continue extending to maintain the flatness of the fabric. As cylinder 601 extends further, one end of lifting beam 602 will continue to push blade body 604 downwards, while the other end of lifting beam 602 will slide downwards along sliding groove 608. In this way, a set of cylinders 601 can effectively complete the smoothing and cutting operations of the fabric.

[0025] like Figure 2 and Figure 4 As shown, the dust extraction mechanism 7 includes a dust extraction nozzle 702 that is movably and slidably installed in the second slide groove 4. A dust extraction pipe 701 is fixedly installed on the dust extraction nozzle 702. An active rack 703 is fixedly installed on one side of the dust extraction nozzle 702. A driven rack 706 is fixedly installed on the side wall of the scraper body 605. A transmission gear 704 is provided between the driven rack 706 and the active rack 703. A movable shaft 705 is fixedly installed on the transmission gear 704. A bearing is provided in the mounting bracket 1. The movable shaft 705 is rotatably installed in the mounting bracket 1 through the bearing.

[0026] Specifically, the contraction of cylinder 601 causes the connected scraper body 605 to move upward. As the scraper body 605 rises, it further causes the driven rack 706 to move upward as well. The upward movement of the driven rack 706 causes the transmission gear 704 to begin rotating. The rotation of the transmission gear 704 causes the driving rack 703 to move downward. Subsequently, the descent of the driving rack 703 causes the dust extraction nozzle 702 to move downward as well. When the dust extraction nozzle 702 moves downward to the cutting position, it can effectively abut against that position, thereby adsorbing the debris generated during the cutting process. In this way, the dust extraction nozzle 702 can quickly clean up all the debris generated during cutting, keeping the working area clean.

[0027] Working principle: In use, first connect the air pump to the dust extraction pipe 701. Then, control the extension of the cylinder 601. After the cylinder 601 extends, it will drive the lifting beam 602 to move downward. After the lifting beam 602 moves downward, it will drive the blade body 604 and the scraper body 605 to move downward. Since the lower end of the scraper body 605 is slightly lower than the lower end of the blade body 604, when the blade body 604 and the scraper body 605 move downward, the scraper body 605 will first come into contact with the fabric surface, thereby pulling the fabric through the scraper body 605 and smoothing the fabric. After the fabric is smoothed, control the cylinder 601 to continue extending. After the cylinder 601 continues to extend, one end of the lifting beam 602 will drive the blade body 604 to move downward, while the other end of the lifting beam 602 will slide downward along the sliding groove 608. Thus, the smoothing and cutting of the fabric is achieved by using a set of cylinders 601. After cutting is completed, cylinder 601 can be retracted. Retracting cylinder 601 will drive scraper body 605 to move upward. After scraper body 605 moves upward, it will drive driven rack 706 to move upward. After driven rack 706 moves upward, it will drive transmission gear 704 to rotate. After transmission gear 704 rotates, it will drive drive rack 703 to move downward. After drive rack 703 moves downward, it will drive dust extraction nozzle 702 to move downward. When moving downward, dust extraction nozzle 702 can come into contact with the cutting position and suck up the debris generated during cutting, quickly cleaning up the debris generated during cutting.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
