Technical Field

[0001] This utility model belongs to the field of cardboard box cutting technology, specifically a blade changing structure for a cardboard box cutting mold. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. In the production and processing of cardboard boxes, it is often necessary to cut the cardboard boxes using cutting molds. After prolonged use, the cutting blades will wear out and need to be replaced.

[0003] Meanwhile, a carton cutting mold with application number 202321807660.1 includes a mold body and a pushing mechanism disposed on the outer wall of the mold body. The pushing mechanism includes a telescopic component; the telescopic component includes a push rod and a telescopic rod. The outer wall of the mold body is provided with a carton body, and an electric push rod is fixedly connected to the outer wall of the mold body. One end of the electric push rod is fixedly connected to a cutting blade located above the carton body. This utility model, by setting a push rod, improves the automatic feeding of the cut carton and the effective cleaning of debris on the mold surface after cutting when the carton is being cut by the cutting mold. After the carton needs to be cut, the cutting blade slides along the inner wall of the slide groove. Through the connection of the pulling rod, the push rod, which is fixedly connected to the telescopic rod, is driven to telescopically move along one side of the carton, realizing convenient feeding of the carton and effective cleaning of debris on the mold table.

[0004] However, the following problems were found in the implementation of the relevant technology: a carton cutting mold cannot quickly change the blade according to the usage requirements, which wastes a lot of time and energy of the staff and reduces the staff's work efficiency.

[0005] To address this, we propose a blade-changing structure for a cardboard box cutting mold. Utility Model Content

[0006] To address the problems mentioned in the background section, this utility model provides a blade-changing structure for a carton cutting mold.

[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a blade changing structure for a carton cutting mold, including a support plate 1, a support frame 5 slidably disposed on the outer side of the support plate 1, a fixing block 9 slidably disposed on the outer side of the support frame 5, a blade head 10 embedded in the outer side of the fixing block 9, a first limiting slide post slidably disposed inside the fixing block 9, a limiting plate fixedly disposed on the outer side of the first limiting slide post, a second limiting slide post slidably disposed inside the fixing block 9, and the bottom end of the second limiting slide post is in contact with the outer side of the limiting plate. Pulling the second limiting slide post upward separates the second limiting slide post from the limiting plate.

[0024] Specifically, a second sliding groove 18 is provided on the outer side of the support plate 1, a first threaded rod 2 is rotatably provided inside the second sliding groove 18, a first slider 4 is sleeved on the outer side of the first threaded rod 2, and the inner wall of the support frame 5 is fixedly connected to the outer side of the first slider 4. The movement of the first slider 4 drives the support frame 5 to move.

[0025] Furthermore, a first groove 6 is provided on the upper outer side of the support frame 5, and a second threaded rod 7 is rotatably provided inside the first groove 6. A second slider 8 is spirally sleeved on the outer side of the second threaded rod 7, and the second slider 8 is fixedly connected to the outer side of the fixing block 9. The rotation of the second threaded rod 7 drives the second slider 8 to slide inside the first groove 6.

[0026] Furthermore, a third groove 19 is provided on the outer side of the other end of the support plate 1. A slide rod 3 is fixedly provided inside the third groove 19. A third slider 20 is slidably provided on the outer side of the slide rod 3. The outer side of the third slider 20 is fixedly connected to the inner wall of the other side of the support frame 5. The movement of the support frame 5 causes the third slider 20 to slide on the outer side of the slide rod 3 inside the third groove 19.

[0027] It is worth noting that a first spring is sleeved on the outer side of the first limiting slide, and the other end of the first spring is in contact with the outer side of the limiting plate. The first spring undergoes elastic deformation to dampen and limit the movement.

[0028] It is worth noting that a second spring is sleeved on the outer side of the second limiting slide, and the other end of the second spring is in contact with the inner wall of the fixing block 9. The second spring undergoes elastic deformation to dampen and limit the movement.

[0029] It is worth mentioning that a first motor 16 is fixedly installed on the outer side of the support plate 1, and the output end of the first motor 16 passes through the support plate 1 and is fixedly connected to the first threaded rod 2. The rotation of the output end of the first motor 16 drives the first threaded rod 2 inside the second slide groove 18 to rotate.

[0030] It is worth emphasizing that a second motor 17 is fixedly installed on the outside of the support frame 5, and the output end of the second motor 17 passes through the support frame 5 and is fixedly connected to the second threaded rod 7. The rotation of the output end of the second motor 17 drives the second threaded rod 7 to rotate.

[0031] The cutter head 10, the first motor 16, and the second motor 17 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: When changing the cutter head 10, the operator first pulls the second limiting slide upwards to separate it from the limiting plate. The second spring then undergoes elastic deformation to dampen and limit the movement. Pulling the first limiting slide then causes it to slide, moving the limiting plate. The first spring then undergoes elastic deformation to dampen and limit the movement, separating the first limiting slide from the cutter head 10. The cutter head 10 is then slid upwards to remove it. This allows for quick replacement of the cutter head 10 during use, saving operators significant time and effort and improving work efficiency. The first motor 1 is then started. 6. The output end of the first motor 16 rotates, causing the first threaded rod 2 inside the second slide groove 18 to rotate. The rotation of the first threaded rod 2 causes the first slider 4 to move. The movement of the first slider 4 causes the support frame 5 to move. The movement of the support frame 5 causes the third slider 20 to slide outside the slide rod 3 inside the third slide groove 19. The second motor 17 is started. The output end of the second motor 17 rotates, causing the second threaded rod 7 to rotate. The rotation of the second threaded rod 7 causes the second slider 8 to slide inside the first slide groove 6. The sliding of the second slider 8 causes the cutter head 10 outside the fixed block 9 to move, thereby achieving the purpose of cutting the carton.
