Description

Technical Field

[0001] This utility model relates to the field of curtain cutting equipment technology, and more specifically, it relates to a curtain cutting machine. Background Technology

[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood chips, and metal. They have the functions of shading, heat insulation, and regulating indoor light. Fabric curtains are classified by material, including cotton gauze, polyester fabric, polyester-cotton blend, cotton-linen blend, and non-woven fabric. With the rapid development of the home decoration industry, curtains, as an important part of home decoration, are experiencing a continuous increase in market demand.

[0003] A curtain cutting machine is a mechanical device used to cut curtain fabric. It cuts large pieces of curtain fabric into smaller pieces for easier processing. During the cutting process, a limiting mechanism is used to restrict the fabric and prevent the curtain from moving during cutting. After the cutter finishes cutting, the limiting mechanism is released, the cut curtain is removed, and a new curtain is pulled to repeat the process. However, existing limiting mechanisms are usually a pressure roller. While the pressure roller helps to limit the curtain and flatten it, in actual production, the contact area between the pressure roller and the curtain is very small. This makes the curtain prone to moving during cutting, resulting in uneven cutting and affecting the production of curtains.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a curtain cutting machine in order to solve the above-mentioned problems.

[0007] The present invention is further configured such that: the limiting protrusion slides in cooperation with the limiting rod, the limiting rod has a cavity that slides in cooperation with the limiting protrusion, the limiting protrusion has symmetrically distributed protrusions that abut against the inner wall of the cavity, the lower end of the limiting protrusion has a protruding post, and the protruding post is fitted with a spring that abuts against the inner wall of the cavity.

[0008] The present invention is further configured such that: the limiting protrusion is detachably installed, the limiting rod is provided with a through groove communicating with the cavity, and the protrusion slides in cooperation with the through groove.

[0009] The present invention is further configured such that: a rubber block is provided on the limiting rod to engage with the through groove, and the rubber block is connected to the limiting rod by a pull rope.

[0010] The present invention is further configured such that: an annular guide surface is provided on the limiting protrusion, and a polyurethane gasket is fixedly connected to the limiting protrusion.

[0011] The present invention is further configured such that: the driving mechanism includes a turntable fixedly connected to the limiting rod, a connecting rod is fixedly connected to the turntable, and the cutting machine is provided with a locking seat for limiting the connecting rod on one side of the turntable.

[0012] The present invention is further configured such that: the locking seat is L-shaped, and the upper surface of the locking seat is provided with a locking groove for engaging with the connecting rod.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By setting a limiting rod that is rotatably connected to the cutting machine body, and having multiple limiting protrusions on the limiting rod, when the limiting rod needs to be used to limit the curtain, rotating the limiting rod causes the multiple limiting protrusions to simultaneously abut against the curtain. The limiting protrusions increase the contact area with the curtain, thereby effectively limiting the curtain. At the same time, the limiting protrusions slide in conjunction with the limiting rod, so that when the worktable is slightly uneven, the spring located in the limiting rod will apply a continuous force to the limiting protrusions during the contact process between the limiting protrusions and the curtain, making the curtain stick to the worktable, thus ensuring that the limiting rod continuously limits the curtain and prevents the curtain from moving during the cutting process.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In one possible embodiment, please refer to Figure 1 As shown, a curtain cutting machine includes a cutting machine body 1 and a worktable 2 located on the cutting machine body 1. The cutting machine body 1 is provided with a cutter 3 that slides and cooperates with the worktable 2. The cutting machine body 1 is rotatably connected above the worktable 2 with a limiting rod 4 for limiting the curtain. When cutting curtains with the cutting machine, the curtain is laid flat on the worktable 2, and then the curtain is limited by the limiting rod 4. The cutter 3 is used to cut the curtain to obtain small pieces of curtain fabric, which is convenient for processing and production of curtain fabric.

[0024] For further details, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the limiting rod 4 is square in shape, and one side of the limiting rod 4 has multiple equally spaced limiting protrusions 5. When the limiting rod 4 needs to be used to limit the curtain, rotating the limiting rod 4 causes the multiple limiting protrusions 5 to simultaneously abut against the curtain, increasing the contact area and effectively limiting the curtain. A polyurethane gasket 504 is fixedly connected to the limiting protrusion 5, ensuring sufficient friction between the gasket and the curtain. An arc-shaped protrusion 13 is provided on the side of the limiting rod 4 away from the limiting protrusion 5. When the side of the arc-shaped protrusion 13 abuts against the curtain, it helps to flatten the curtain, further preventing the curtain from slipping off the limiting protrusion 5. The limiting protrusion 5 slides with the limiting rod 4, and the limiting rod 4 has a cavity 401 that slides with the limiting protrusion 5. The limiting protrusion 5 has symmetrically distributed... The protrusion 501 abuts against the inner wall of the cavity 401. Through the abutment of the protrusion 501 against the inner wall of the cavity 401, the sliding engagement between the limiting protrusion 5 and the limiting rod 4 is ensured. The lower end of the limiting protrusion 5 is provided with a protruding post 502. The protruding post 502 is sleeved with a spring 7 that abuts against the inner wall of the cavity 401. Thus, when the worktable 2 is slightly uneven, during the process of the limiting protrusion 5 abutting against the curtain, the spring 7 located in the limiting rod 4 will apply a continuous force to the limiting protrusion 5, so that the curtain and the worktable 2 are in contact. This ensures that the limiting rod 4 continuously limits the curtain, thus ensuring that the curtain is not easily moved during the cutting process. At the same time, the limiting protrusion 5 is provided with an annular guide surface 503. Thus, during the rotation of the limiting rod 4, the limiting protrusion 5 can smoothly slide into the limiting rod 4, which is less likely to exert a large force on the curtain and makes the curtain less likely to be damaged.

[0025] For further details, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the limiting protrusion 5 is detachably installed. Therefore, if the elastic limiting capacity of the limiting protrusion 5 is found to be insufficient, the limiting protrusion 5 can be disassembled to replace the spring 7. The limiting rod 4 is provided with a through groove 8 communicating with the cavity 401. The protrusion 501 slides in the through groove 8. By rotating the limiting protrusion 5 until the protrusion 501 is aligned with the through groove 8, pulling the limiting protrusion 5 outwards will separate the limiting protrusion 5 from the limiting rod 4, allowing for the disassembly of the spring 7. After replacement, by aligning and engaging the protrusion 501 of the limiting protrusion 5 with the through groove 8, and then rotating the limiting protrusion 5, the protrusion 501 can be made to re-abut against the inner wall of the cavity 401. The limiting rod 4 is provided with a rubber block 9 that engages with the through groove 8. The rubber block 9 and the limiting rod 4 are connected by a pull rope 10, which can prevent the rubber block 9 from being lost. By engaging the rubber block 9 with the through groove 8, the limiting protrusion 5 can be limited, preventing the limiting protrusion 5 from rotating and sliding out.

[0026] For further details, please refer to Figure 1 and Figure 2 As shown, the main body 1 of the cutting machine is equipped with a drive mechanism 6 for rotating the limiting rod 4. When it is necessary to limit the curtain, the drive mechanism 6 drives the limiting rod 4 to rotate, so that the limiting protrusions 5 on the limiting rod 4 abut against the curtain, thereby limiting the curtain. The drive mechanism 6 includes a turntable 601 fixedly connected to the limiting rod 4, and a connecting rod 602 fixedly connected to the turntable 601. The cutting machine is provided with a locking seat 11 for limiting the connecting rod 602 on one side of the turntable 601. The locking seat 11 is L-shaped, and the upper surface of the locking seat 11 is provided with a locking groove 12 for locking the connecting rod 602. When it is necessary to limit the curtain, the driving mechanism 6 drives the limiting rod 4 to rotate, so that the limiting protrusions 5 on the limiting rod 4 abut against the curtain. When in position, rotate turntable 601 clockwise so that one side of the arc-shaped protrusion 13 abuts against the curtain. Pull the curtain so that the arc-shaped protrusion 13 flattens the curtain. When pulled to the appropriate position, continue to rotate turntable 601 so that the limiting protrusion 5 on the limiting rod 4 abuts against the curtain. At this time, continue to apply force to the connecting rod 602 so that the limiting protrusion 5 on the limiting rod 4 continues to abut against the curtain. After the cutting is completed, rotate turntable 601 counterclockwise so that the connecting rod 602 engages with the slot 12. This engagement can support and limit the limiting rod 4, preventing the limiting rod 4 from rotating, thus making it easier to remove the cut curtain.
