Description

Technical Field

[0001] This utility model relates to the field of label cutting machine technology, specifically a label cutting machine with a winding mechanism. Background Technology

[0002] In the label processing field, label cutting machines are the core equipment for achieving fixed-length label cutting, and are widely used in label production processes in industries such as food packaging, daily chemical products, and electronic components. Traditional label cutting machines mainly consist of an unwinding mechanism, a conveying mechanism, and a cutting mechanism. Their working process is as follows: the unwinding mechanism releases the label roll, the conveying mechanism sends the roll to the cutting mechanism to complete the fixed-length cutting, and finally obtains a single label product.

[0003] In existing label cutting machines, the take-up roller is a key component to ensure the accuracy of label winding. However, most mainstream label cutting machines currently use rigid expansion sleeves and fixed edge guards with fixed diameter clamping structures, which lack the ability to adapt to label rolls of different widths and thicknesses. When the processing width does not match the width of the clamping mechanism, the roll is prone to axial displacement due to insufficient side limits or compression. Furthermore, the fixed clamping force can easily cause deformation or slippage of thin and thick labels. When the diameter of the roll increases during winding, the clamping limit will also fail, further aggravating label deviation, resulting in misalignment between layers of the rolled label, uneven edges, and subsequent labeling deviation and scrapping. Operators need to frequently stop the machine for adjustment, resulting in material waste and reduced efficiency. Therefore, we propose a label cutting machine with a winding mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a label cutter with a winding mechanism to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A label cutting machine with a winding mechanism includes: a label cutting machine body; a cutting mechanism is disposed on the top of the label cutting machine body; a conveying roller is rotatably connected to the label cutting machine body on the left side of the cutting mechanism; a winding roller is rotatably connected to the label cutting machine body on the left side of the conveying roller; a motor for driving the winding roller to rotate is disposed at the rear end of the label cutting machine body; and a clamping assembly is disposed on the winding roller. The clamping assembly includes a support plate fixedly connected to the outer left wall of the label cutting machine body. A guide rail is provided inside the support plate, and two sets of sliders are slidably connected inside the guide rail. A connecting plate is fixedly connected to the right side of the sliders. A sliding ring is fixedly connected to the side of the connecting plate facing the take-up roller. The sliding ring is slidably connected to the take-up roller. Two sets of first baffles are symmetrically fixedly connected to the outer wall of the sliding ring. A threaded seat and a threaded rod are provided at one end of each set of sliders. The threaded seat is rotatably connected to one set of sliders through a bearing, and the threaded rod is fixedly connected to the other set of sliders.

[0006] Preferably, the slider is T-shaped, and the guide rail has a T-slot adapted to the slider.

[0008] Preferably, the first baffle is provided with a baffle assembly, the baffle assembly including a guide groove formed on the outer wall of the first baffle, a second baffle slidably connected in the guide groove, a movable groove formed on the side wall of the second baffle, a spring fixedly connected to the inner wall of the movable groove, a positioning post fixedly connected to the other end of the spring, the positioning post slidably connected to the movable groove, and multiple sets of positioning grooves are formed at equal intervals on the inner wall of the guide groove corresponding to the outer end of the positioning post, the positioning grooves being slidably connected to the positioning post.

[0009] Preferably, one end of the spring is fixedly connected to the middle position of the inner wall of the movable groove, and the other end of the spring is fixedly connected to the middle position of the inner wall of the positioning column.

[0010] Preferably, a pull rod is fixedly connected to the side of the second baffle away from the guide groove, and the pull rod has a round handle design.

[0011] The beneficial effects of this utility model are: This invention uses two sets of connecting plates to drive a slider to slide within a guide rail, causing a threaded seat to rotate on the slider and connect threadedly to a threaded rod.

[0014] 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.

[0015] like Figures 1-4 As shown, a label cutting machine with a winding mechanism includes: a label cutting machine body 1, a cutting mechanism 2 disposed on the top of the label cutting machine body 1, a conveying roller 3 rotatably connected to the label cutting machine body 1 on the left side of the cutting mechanism 2, a winding roller 4 rotatably connected to the label cutting machine body 1 on the left side of the conveying roller 3, a motor 5 disposed at the rear end of the label cutting machine body 1 for driving the winding roller 4 to rotate, and a clamping assembly 6 disposed on the winding roller 4. The clamping assembly 6 includes a support plate 61 fixedly connected to the outer wall of the left side of the label cutting machine body 1, and an opening in the support plate 61. The guide rail 62 has two sets of sliders 63 slidably connected inside it. A connecting plate 64 is fixedly connected to the right side of the sliders 63. A sliding ring 65 is fixedly connected to the side of the connecting plate 64 facing the take-up roller 4. The sliding ring 65 is slidably connected to the take-up roller 4. Two sets of first baffles 66 are symmetrically fixedly connected to the outer wall of the sliding ring 65. A threaded seat 67 and a threaded rod 68 are provided at the corresponding ends of the two sets of sliders 63. The threaded seat 67 is rotatably connected to one set of sliders 63 through a bearing, and the threaded rod 68 is fixedly connected to the other set of sliders 63.

[0016] In practice, two sets of connecting plates 64 drive the slider 63 to slide within the guide rail 62, causing the threaded seat 67 to rotate on the slider 63 and connect threadedly to the threaded rod 68. Then, the threaded seat 67 is rotated, causing it to move along the thread direction of the threaded rod 68. At the same time, the connecting plates 64 drive two sets of sliding rings 65 to fit against the first baffle 66 and both sides of the take-up roller 4, so that the first baffle 66 and the sliding rings 65 limit the trademark take-up range, preventing the trademark from shifting when the take-up roller 4 takes up the trademark. This would lead to misalignment between the layers of the roll label, uneven edges, and subsequent labeling errors, resulting in waste of materials.

[0017] As a technical optimization of this utility model, the slider 63 is designed in a T-shape, and the guide rail 62 is provided with a T-shaped groove that is adapted to the slider 63.

[0018] In practice, this allows the slider 63 to fit fully against the guide rail 62, thereby improving the stability and smoothness of the slider 63 as it slides back and forth within the guide rail 62.

[0019] As a technical optimization of this utility model, the outer wall of the threaded seat 67 is provided with anti-slip texture.

[0020] In practice, this increases the friction between the worker's hand and the threaded seat 67, preventing the hand from slipping when rotating the threaded seat 67.

[0021] As a technical optimization of this utility model, a baffle assembly 7 is provided on the first baffle 66. The baffle assembly 7 includes a guide groove 71 opened on the outer wall of the first baffle 66. A second baffle 72 is slidably connected in the guide groove 71. A movable groove 74 is opened on the side wall of the second baffle 72. A spring 75 is fixedly connected to the inner wall of the movable groove 74. A positioning post 76 is fixedly connected to the other end of the spring 75. The positioning post 76 is slidably connected to the movable groove 74. Multiple sets of positioning grooves 77 are opened at equal intervals on the inner wall of the guide groove 71 corresponding to the outer end of the positioning post 76. The positioning grooves 77 are slidably connected to the positioning post 76.

[0022] In practice, the second baffle 72 slides within the guide groove 71, causing the positioning pin 76 to align sequentially with multiple sets of positioning grooves 77. Then, the restoring force of the spring 75 pushes the positioning pin 76 to reset and slide within the movable groove 74, allowing the positioning pin 76 to pass through the positioning grooves 77 sequentially. This achieves the purpose of adjusting the protection and blocking range of the second baffle 72, enabling the second baffle 72 to be positioned according to trademarks of different thicknesses, thereby ensuring the stability of the trademark during winding.

[0023] As a technical optimization of this utility model, one end of the spring 75 is fixedly connected to the middle position of the inner wall of the movable groove 74, and the other end of the spring 75 is fixedly connected to the middle position of the inner wall of the positioning post 76.

[0024] In practice, the elastic force generated when the spring 75 is compressed is evenly transmitted to the positioning post 76, so that the positioning post 76 is not easily stuck when it slides back in the movable groove 74, thus ensuring the smoothness of the positioning post 76 when it slides.

[0025] As a technical optimization of this utility model, a pull rod 73 is fixedly connected to the side of the second baffle 72 away from the guide groove 71, and the pull rod 73 is designed in the shape of a round handle.

[0026] In practice, it is convenient for staff to use the pull rod 73 to drive the second baffle 72 to slide in the guide groove 71, thereby adjusting the position of the second baffle 72.

[0027] In use, this invention first slides the pull rod 73 within the second baffle 72, and two sets of springs 75 are fitted onto the take-up roller 4. Then, the threaded seat 67 rotates on the slider 63 and is threadedly connected to the threaded rod 68. Next, the threaded seat 67 is rotated, causing it to move along the thread direction of the threaded rod 68. Simultaneously, the connecting plate 64 drives two sets of sliding rings 65 to adhere to the first baffle 66 and both sides of the take-up roller 4. This limits the trademark winding range of the first baffle 66 and the sliding rings 65, preventing the trademark from shifting when the take-up roller 4 winds up the trademark. This prevents misalignment between layers of the rolled label, uneven edges, and subsequent labeling errors that could lead to waste of materials.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
