Description

Technical Field

[0001] This utility model belongs to the technical field of pearl cotton processing equipment, specifically relating to a precision cutting device for pearl cotton. Background Technology

[0002] In the field of pearl cotton processing, the precision of cutting equipment directly affects product quality. In existing technologies, the cutting blade often uses a simple cylinder to drive linear motion, but it is prone to shaking or deviation during the pressing process, resulting in uneven cutting surfaces and inaccurate dimensions, making it difficult to meet the requirements of high-precision cutting.

[0003] Therefore, there is an urgent need to provide a precision cutting device for pearl cotton to solve the problems mentioned in the background art. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a precision cutting device for pearl cotton to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a precision cutting device for pearl cotton, comprising: a worktable, on which a conveyor belt, a pressing assembly, and a cutting assembly are provided; the cutting assembly includes a second bracket, which is installed on both sides of the worktable; a second mounting plate is embedded in the upper end of the second bracket; a second cylinder is provided at the upper end of the second mounting plate; a second telescopic rod is provided at the lower end of the second cylinder; one end of the second telescopic rod passes through the second mounting plate and is connected to a connecting plate; a cutter is provided at the lower end of the connecting plate; hinge joints are provided on both sides of the second mounting plate; two first hinge rods are hinged to the hinge joints; one end of each of the two first hinge rods is hinged to a second hinge rod; one end of each of the two second hinge rods is hinged to the cutter; third hinge rods are provided on both sides of the connecting plate; the two ends of each of the third hinge rods are respectively hinged to the hinge joints of the adjacent first and second hinge rods.

[0006] As further explained, the first hinge rod, the second hinge rod, and the third hinge rod do not contact the connecting plate during movement.

[0007] As further explained, the second bracket is provided with two guide grooves, and the two ends of the cutter are respectively placed in the two guide grooves.

[0008] As further explained, the pressing assembly includes a first bracket, which is installed on both sides of the workbench. A first mounting plate is embedded in the upper end of the first bracket. A first cylinder is provided at the upper end of the first mounting plate. A first telescopic rod is provided at the lower end of the first cylinder. One end of the first telescopic rod passes through the first mounting plate and is connected to a circular plate. Both sides of the circular plate are provided with hinge grooves. A push rod is hinged to the lower end of each of the two hinge grooves. A spring is connected in the middle of the two push rods. A connecting frame is provided at the lower end of each of the two push rods. A flattening roller is movably connected to the lower end of each of the two connecting frames.

[0009] As further explained, both the pressing component and the cutting component span across the upper end of the conveyor belt.

[0010] As further explained, the conveyor belt rotates from the pressing component to the cutting component.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a unique hinged linkage mechanism composed of a first hinge rod, a second hinge rod, and a third hinge rod to collaboratively drive the cutter with a second cylinder. When the second telescopic rod is pressed down, this mechanism smoothly transmits the vertical driving force and converts it into the vertical movement of the cutter. Simultaneously, it forms a stable "three-point" guiding constraint on both sides, effectively suppressing any swaying or deviation of the cutter in any direction during the downward cutting process, ensuring the absolute verticality and stability of the cutting path, thereby greatly improving the flatness and dimensional accuracy of the cut surface.

[0012] 2. The two guide grooves set on the second bracket cooperate with the two ends of the cutter, providing precise physical guidance and limiting for the movement of the cutter, further enhancing the stability of the cutting process, preventing the cutter from tilting due to uneven force, and ensuring the reliability of the equipment in long-term operation.

[0013] 3. The pressing component installed before the cutting station uses a cylinder to drive the flattening roller downwards, and utilizes the elastic pressure of a spring to effectively press and stretch the pearl cotton before cutting. This design eliminates wrinkles or curls in the pearl cotton material itself, keeping it flat and taut at the moment of cutting, thus avoiding cutting deformation or dimensional errors caused by uneven material, and further ensuring the final cutting quality from the source.

The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1-3A precision cutting device for pearl cotton includes: a workbench 1, a conveyor belt 2, a pressing component 3, and a cutting component 4 on the workbench 1. The conveyor belt 2 is made of a cut-resistant material, such as polyurethane. The cutting component 4 includes a second bracket 401, which is installed on both sides of the workbench 1. A second mounting plate 402 is embedded in the upper end of the second bracket 401. A second cylinder 403 is provided on the upper end of the second mounting plate 402. A second telescopic rod 404 is provided at the lower end of the second cylinder 403. One end of the second telescopic rod 404 passes through the second mounting plate 402 and is connected to... A connecting plate 405 has a cutter 406 at its lower end. A second bracket 401 has hinge joints 407 on both sides of the second mounting plate 402. Each hinge joint 407 is hinged to two first hinge rods 408, one end of which is hinged to a second hinge rod 409. One end of each second hinge rod 409 is hinged to the cutter 406. Third hinge rods 410 are located on both sides of the connecting plate 405, with their ends respectively hinged to the hinge points of adjacent first hinge rods 408 and second hinge rods 409. This design employs a unique hinge linkage mechanism to drive and stabilize the cutter 406. The key point is that when the second cylinder 403 drives the connecting plate 405 and the cutter 406 to rise and fall via the second telescopic rod 404, the hinge joints 407, the first hinge rod 408, the second hinge rod 409, and the third hinge rod 410 on both sides of the second bracket 401 form a symmetrical parallelogram linkage mechanism. The entire linkage structure maintains geometric symmetry throughout the movement, evenly distributing the single-point driving force of the second cylinder 403 to both sides of the cutter 406, thus counteracting the swaying caused by uneven force on one side. At the same time, this linkage mechanism can limit the cutter 406 to move only in the vertical direction, avoiding lateral deviation. The linkage design of the hinge rod group forms a dual guarantee of mechanical limitation and guidance, effectively solving the problem of uneven cutting surface and dimensional deviation caused by the swaying of the cutter 406 during the downward pressing process of traditional cutting equipment, and significantly improving cutting accuracy.

[0021] The first hinge rod 408, the second hinge rod 409, and the third hinge rod 410 do not contact the connecting plate 405 during movement. This clear separation between the three hinge rods and the connecting plate 405 ensures that the entire linkage mechanism's motion trajectory is independent and clearly defined, preventing friction or collision between the linkage mechanism and the connecting plate 405 during lifting. The three hinge rods rotate only around their own hinge points, and the connecting plate 405 only moves vertically with the second telescopic rod 404; their motion trajectories are completely independent, with no physical contact whatsoever.

[0022] The second support 401 is provided with two guide grooves 411, and the two ends of the cutter 406 are respectively placed in the two guide grooves 411. When the cutter 406 is raised and lowered, its two ends can only slide along the vertical direction of the guide grooves 411, completely blocking the possibility of lateral deviation or tilting, forming a "double stability guarantee" with the parallelogram mechanism of multiple hinge rods.

[0023] The pressing assembly 3 includes a first bracket 301, which is mounted on both sides of the workbench 1. A first mounting plate 302 is embedded in the upper end of the first bracket 301. A first cylinder 303 is provided on the upper end of the first mounting plate 302. A first telescopic rod 304 is provided at the lower end of the first cylinder 303. One end of the first telescopic rod 304 passes through the first mounting plate 402 and is connected to a circular plate 305. Both sides of the circular plate 305 are provided with hinge grooves 306. A push rod 307 is hinged to the lower end of each of the two hinge grooves 306. The circular plate 305 can respectively limit the two push rods 307 within the two hinge slots 306. The two push rods 307 at the lower end of the hinge slots 306 can only rotate upwards within the hinge slots 306, that is, the two push rods 307 rotate in opposite directions. A spring 308 is connected between the two push rods 307. The spring 308 can pull the two push rods 307 back after they have moved in opposite directions. Each push rod 307 has a connecting frame 309 at its lower end, and a flattening roller 310 is movably connected to the lower end of the two connecting frames 309. In this invention, the first cylinder 303 presses down, and the pressure is transmitted to the flattening roller 310 through a hinged linkage mechanism with a spring 308. The spring 308 and the hinge structure enable the flattening roller 310 to adapt to the unevenness of the pearl cotton surface and apply a flexible and uniform pressing force. The rolling pressing of the flattening roller 310 can effectively eliminate local wrinkles or arches in the pearl cotton and prevent cutting deviations caused by material displacement or deformation during cutting.

[0024] Both the pressing component 3 and the cutting component 4 span across the upper end of the conveyor belt 2, forming a covered working structure to ensure that the pearl cotton is always within the effective range of the pressing component 3 and the cutting component 4 during the conveying process.

[0025] The conveyor belt 2 moves from the pressing component 3 to the cutting component 4. The pearl cotton is first pressed and shaped by the pressing component 3, and then enters the cutting component 4 for precise cutting. This ensures that the material is in a flat and stable state before cutting, which can solve the problem of cutting accuracy caused by material deformation, and at the same time improve the continuity and efficiency of the production process.
