Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, and in particular to a cutting device for a fully automatic paper tube cutting machine that facilitates paper tube fixing. Background Technology

[0002] Paper tube cutters are widely used in printing, packaging, leather, and home furnishing industries. They are especially suitable for plastic or paper tubes used in labels, non-woven fabrics, films, and tapes. When using a paper tube cutter, it can ensure that the surface of the paper tube is smooth and uneven, without frayed edges or fuzz. It is easy to use and has a wide range of applications.

[0003] For example, CN216682441U discloses a cutting device for a fully automatic paper tube cutter that facilitates paper tube fixing. It includes a base platform, side plates installed on both sides of the top of the base platform, and suction mechanisms provided on the top of the outer side of each side plate. A support platform is connected between the side plates, and sliding grooves are provided on both sides inside the support platform, with sliders slidably installed inside each sliding groove.

[0004] However, in the existing technology, traditional paper tube cutting equipment mostly uses unidirectional clamping or simple buckle fixing, and the paper tube is subjected to a single force point. During cutting, the blade comes into contact with the paper tube and generates radial friction, which can easily cause the paper tube to rotate around the axis or move axially, resulting in problems such as tilted cutting end face and excessive length deviation. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the paper tube is fixed by unidirectional clamping or simple buckle, resulting in a single stress point. Therefore, this invention proposes a cutting device for a fully automatic paper tube cutter that facilitates paper tube fixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for a fully automatic paper tube cutter that facilitates paper tube fixing, comprising a fixing frame, a cylinder installed at the top of the fixing frame, and a positioning mechanism installed on the side wall of the fixing frame;

[0007] The positioning mechanism includes a mounting frame, a first rotating plate rotatably connected to the side wall of the mounting frame, a movable block rotatably connected to the bottom end of the first rotating plate, a threaded rod threadedly connected to the inner side of the movable block, a rotating block rotatably connected to the outer surface of one end of the threaded rod, the rotating block being rotatably connected to the side wall of the mounting frame, a rotating sleeve rotatably connected to the side wall of the first rotating plate, a drive rod slidably connected to the inner side of the rotating sleeve, and a limit wheel rotatably connected to the inner side of one end of the drive rod.

[0008] Preferably, one end of the drive rod is fixedly connected to a rotating rod, and one end of the rotating rod is rotatably connected to the side wall of the mounting frame.

[0009] Preferably, a second rotating plate is fixedly connected to the side wall of the first rotating plate, and the side wall of the rotating sleeve is rotatably connected to the second rotating plate.

[0010] Preferably, a cylinder is installed at the center of the top of the fixed frame, and a lifting plate is fixedly connected to the output end of the cylinder.

[0011] Preferably, a cutting machine is fixedly connected to the center of the bottom of the lifting plate, and limit rods are symmetrically fixedly connected to the top of the lifting plate.

[0012] Preferably, the top of the limiting rod passes through the fixing frame, and the limiting rod is slidably connected to the fixing frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during the paper tube cutting process, the rotation drive of the threaded rod causes the movable block to move smoothly along its surface, and the threaded rod engages with the internal thread groove of the movable block to ensure precise sliding. The movement of the movable block drives the first rotating plate to move, and through its connection with the rotating block, the rotating block rotates, further pushing the first rotating plate to rotate. This process affects the rotation of the second rotating plate. During the rotation, the engagement of the first rotating plate with the rotating sleeve drives the movement of the drive rod. The drive rod rotates around the rotating rod as the central axis. Through the cooperation of the three drive rods, the limiting wheel at the end of the drive rod accurately contacts the paper tube, fixing the paper tube through physical resistance and preventing it from tilting or shifting during the cutting process.

[0015] 2. In this utility model, the lifting plate can be precisely controlled by the cylinder drive, thereby driving the cutting machine below to perform cutting operations, ensuring the accuracy and stability of the cutting. The relative sliding between the limit rod and the fixed frame helps the lifting plate to rise and fall stably, avoiding deviation or tilting, improving stability, and preventing work accuracy problems caused by structural instability or error accumulation, ensuring the stability of the cutting process and the accuracy of the cutting results. When the rotating plate rotates, the sliding relationship between the drive rod and the rotating sleeve helps to adjust the position of the limit wheel, ensuring that the limit wheel accurately locks the position of the paper tube.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a cutting device for a fully automatic paper tube cutter that facilitates paper tube fixing, including a fixing frame 2, a cylinder 21 installed at the top of the fixing frame 2, and a positioning mechanism 1 installed on the side wall of the fixing frame 2;

[0024] The positioning mechanism 1 includes a mounting frame 11, a first rotating plate 15 rotatably connected to the side wall of the mounting frame 11, a movable block 14 rotatably connected to the bottom end of the first rotating plate 15, a threaded rod 13 threadedly connected to the inner side of the movable block 14, a rotating block 12 rotatably connected to the outer surface of one end of the threaded rod 13, the rotating block 12 being rotatably connected to the side wall of the mounting frame 11, a rotating sleeve 17 rotatably connected to the side wall of the first rotating plate 15, a drive rod 16 slidably connected to the inner side of the rotating sleeve 17, and a limit wheel 18 rotatably connected to the inner side of one end of the drive rod 16.

[0025] The specific settings and functions of this embodiment will be described in detail below. During the cutting process of the paper tube, firstly, the rotation drive of the threaded rod 13 is used to make the connected movable block 14 move smoothly along the surface of the threaded rod 13. This movement is achieved through the interaction between the thread and the internal thread groove of the movable block 14, so that the movable block 14 can slide precisely along a predetermined trajectory.

[0026] As the movable block 14 moves, its translational movement, connected to the first rotating plate 15, directly causes the first rotating plate 15 to move accordingly. During this process, the rotational movement of the threaded rod 13, through its connection with the rotating block 12, causes the rotating block 12 to rotate, further driving the first rotating plate 15 to rotate. The rotation of the first rotating plate 15 directly affects the second rotating plate 19 mounted on the mounting bracket 11, causing it to rotate as well.

[0027] During this rotation, the mechanical engagement between the first rotating plate 15 and the rotating sleeve 17 drives the movement of the drive rod 16. The drive rod 16 rotates around the rotating rod 171 as its central axis. Through this movement, the first rotating plate 15 simultaneously engages with all three drive rods 16, thereby creating a locking effect on the paper tube at the other end of the drive rod 16. In particular, the limiting wheel 18 at the end of the drive rod 16 precisely contacts the paper tube, and through the physical resistance and clamping action of the limiting wheel 18, the paper tube is firmly fixed in the designated position.

[0028] The coordinated operation of the three drive rods 16 not only ensures the stability of the paper tube during the cutting process, but also effectively prevents the paper tube from tilting or shifting during the cutting process.

[0029] Example 2: Figure 2 - Figure 4 As shown, a rotating rod 171 is fixedly connected to one end of the drive rod 16, and one end of the rotating rod 171 is rotatably connected to the side wall of the mounting frame 11. A second rotating plate 19 is fixedly connected to the side wall of the first rotating plate 15, and the side wall of the rotating sleeve 17 is rotatably connected to the second rotating plate 19. A cylinder 21 is installed at the top center of the fixed frame 2, and a lifting plate 23 is fixedly connected to the output end of the cylinder 21. A cutting machine 24 is fixedly connected to the bottom center of the lifting plate 23, and limit rods 22 are symmetrically fixedly connected to the top of the lifting plate 23. The top end of the limit rod 22 passes through the fixed frame 2, and the limit rod 22 is slidably connected to the fixed frame 2.

[0030] The overall effect of this embodiment is that the cylinder 21 precisely controls the lifting and lowering movement of the lifting plate 23, thereby driving the cutting machine 24 below the lifting plate 23 to perform cutting operations. During this process, the relative sliding between the limit rod 22 and the fixed frame 2 ensures the stable lifting and lowering of the lifting plate 23, preventing deviation or tilting and guaranteeing smooth operation. This design effectively prevents accuracy problems caused by structural instability or error accumulation during lifting, thereby improving the stability of the cutting process and the accuracy of the cutting results.

[0031] When the first rotating plate 15 begins to rotate, the movement of the drive rod 16 not only causes it to rotate around the axis of the rotating rod 171, but also causes it to slide relative to the rotating sleeve 17. This sliding relationship is to more precisely control the position of the limit wheel 18, ensuring that the limit wheel 18 can accurately lock the corresponding position of the paper tube during operation. Through this ingenious linkage design, the three limit wheels 18 can simultaneously lock the stability of the paper tube during rotation, thereby preventing the paper tube from shifting or rotating during cutting or processing, ensuring high precision and high consistency in processing quality.

[0032] The operating principle and usage of this device are as follows: When cutting the paper tube, the rotation of the threaded rod 13 causes the movable block 14 to move on its surface. During the movement of the movable block 14, the first rotating plate 15 moves synchronously. At the same time, the threaded rod 13 drives the rotating block 12 to rotate, which in turn causes the movable block 14 to drive the first rotating plate 15 to rotate on the surface of the mounting frame 11. At this time, the first rotating plate 15 drives the second rotating plate 19 to move together, and drives the drive rod 16 to rotate around the rotating rod 171 through the rotating sleeve 17. In this way, when the first rotating plate 15 drives the three drive rods 16 to move simultaneously, the limiting wheel 18 at one end of the three drive rods 16 can lock the paper tube, ensuring that the paper tube remains stable during cutting and does not become skewed.

[0033] The cylinder 21 drives the lifting plate 23 to rise and fall, allowing the cutting machine 24 below the lifting plate 23 to complete the cutting operation. During this process, the limit rod 22 slides relative to the fixed frame 2, which can effectively prevent the lifting plate 23 from deviating during the rise and fall.

[0034] Furthermore, when the first rotating plate 15 rotates and drives the drive rod 16 to move, the drive rod 16 not only rotates around the rotating rod 171, but also slides relative to the rotating sleeve 17. This facilitates control of the position of the limit wheels 18, thereby ensuring that the three limit wheels 18 accurately lock the paper tube.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
