Description

Technical Field

[0001] This utility model belongs to the technical field of textile machinery, specifically relating to a high-efficiency cutting device for producing plain polyester-cotton-linen fabric. Background Technology

[0002] High-efficiency cutting devices for polyester-cotton-linen plain weave fabric production are key equipment in the post-processing of polyester-cotton-linen plain weave fabric. Among them, hydraulic cutting machines are the most widely used. These devices rely on hydraulically driven punching structures to punch stacked polyester-cotton-linen plain weave fabrics in batches. They can adapt to the cutting needs of fabrics of different thicknesses and can complete multiple identical cut pieces in a single punching, which greatly improves the efficiency of mass production scenarios such as workwear fabrics and home textile fabrics. At the same time, they ensure that the cutting edges are neat and meet the processing precision requirements of polyester-cotton-linen plain weave fabrics.

[0003] However, existing hydraulic cutting machines have high cutting force and fast descent speed. When operators are arranging and stacking fabrics or adjusting the position of cut pieces, if the punch descends prematurely due to accidental touch of control buttons or equipment signal delays, it is very easy to cause hand injuries. In addition, traditional equipment lacks effective physical protection mechanisms and it is difficult to stop the cutting action in time. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency cutting device for the production of plain polyester-cotton-linen fabric, in order to solve the problems mentioned in the background art, such as the large cutting force and rapid descent of existing hydraulic cutting machines, the premature descent of the punch when operators are sorting the fabric or adjusting the cut pieces due to accidental button presses or equipment signal delays, which can easily injure hands, and the lack of effective physical protection in traditional equipment, making it difficult to stop the cutting action in time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cutting device for producing plain polyester-cotton-linen fabric, comprising a main unit housing and hydraulic cylinders fixed at approximately four corners inside the main unit housing, each hydraulic cylinder having a hydraulic shaft, a cutting top box being provided above the main unit housing, with fixed shaft seats welded to the bottom of both its left and right ends, and the top ends of multiple hydraulic shafts being fixedly connected to the fixed shaft seats at corresponding positions, the hydraulic cylinders driving the cutting top box to move up and down via the hydraulic shafts, and a personal safety protection device being provided at the front end of the top of the cutting top box.

[0006] Preferably, the personal safety protection device includes a U-shaped corner sleeve and a metal fixing sleeve. The metal fixing sleeve is fitted onto the top corner of the front end of the cutting top box, and the two are fixedly connected by welding. The left and right ends of the metal fixing sleeve and the outer wall of the front end are both welded with U-shaped corner sleeves, and the U-shaped openings face forward.

[0007] Preferably, the personal safety protection device further includes a metal blocking bracket A, a connecting shaft, and a metal blocking bracket B. The metal blocking bracket A and the metal blocking bracket B are arranged symmetrically on the left and right, and their top ends are respectively inserted into two U-shaped corner sleeves. The metal blocking bracket A and the metal blocking bracket B are connected to the two U-shaped corner sleeves by the connecting shaft.

[0008] Preferably, the personal safety protection device further includes two resistance sleeves, and the connecting shaft passes through the metal blocking bracket A and the metal blocking bracket B and the two U-shaped corner sleeves respectively. The connecting shaft is fixedly connected to the metal blocking bracket A and the metal blocking bracket B by welding. The two resistance sleeves are respectively welded to the outer wall of one side of the two U-shaped corner sleeves in opposite directions, and both resistance sleeves are sleeved outside the connecting shaft.

[0009] Preferably, when the metal blocking bracket A or the metal blocking bracket B rotates independently, it will drive the metal blocking bracket B or the metal blocking bracket A to rotate synchronously through the connecting shaft. When the metal blocking bracket A or the metal blocking bracket B stops rotating, the resistance sleeve applies resistance to the connecting shaft to prevent it from rotating.

[0010] Preferably, the personal safety protection device further includes a metal blocking block, a reset rotating counterweight block, and an opening handle. When both metal blocking bracket A and metal blocking bracket B are in a downward vertical state, a reset rotating counterweight block is welded to the outer wall of both near the bottom front end, and an opening handle is provided above both reset rotating counterweight blocks. Metal blocking blocks fixed to the outer wall of the front end of the main unit box are provided below both metal blocking bracket A and metal blocking bracket B in the downward vertical state.

[0011] Preferably, the metal blocking block can apply weight to the metal blocking bracket A and the metal blocking bracket B so that they resist the resistance of the resistance sleeve and rotate downward to a vertical state, while the opening handle can pull the metal blocking bracket A and the metal blocking bracket B forward to rotate.

[0012] Preferably, a long strip-shaped blade holder is horizontally fixed to the front side of the center of the bottom end of the cutting top box, and a cutting blade is fixed to its front end by multiple screws. When the cutting blade is in the uncutting reset state, the distance between the bottom end of the vertical metal blocking bracket A and the top end of the metal blocking block is equal to the vertical height of the metal blocking block, so as to ensure that the metal blocking bracket A and the metal blocking bracket B can rotate to the vertical state without obstruction.

[0013] Preferably, the cutting top box has a controller at the front center, which is electrically connected to the main unit box of the device. Maintenance windows are opened inside the top of the cutting top box and inside the left and right ends of the main unit box of the device, and protective plates are fixed in the maintenance windows with screws.

[0014] Preferably, the device's main unit is equipped with lifting protective covers at the top of both the left and right ends. The two lifting protective covers protect the outside of the cutting top box at the left and right ends respectively, and the maximum height of the cutting top box's upward movement must be the same as the height of the lifting protective covers.

[0015] Preferably, the device's main unit chassis has mounting rails on both the left and right sides of the front center, which are flush with the top outer wall of the main unit chassis. Stacking plates are placed on the mounting rails and the top outer wall of the main unit chassis, and a push-pull adjustment handle is provided at the front top of the stacking plates.

[0016] Compared with the prior art, this utility model provides a high-efficiency cutting device for producing polyester-cotton-linen plain weave fabric, which has the following beneficial effects:

[0017] This utility model adds a personal safety protection device to the front of the cutting top box and the main unit box of the device. This device can automatically form a protective barrier when the cutting device is not in operation, to prevent the cutting blade from falling prematurely and injuring people due to misoperation. At the same time, it is compatible with the normal cutting operation process, which not only ensures the safety of operators, but also does not affect production efficiency. Specifically, when the cutting blade is not cutting, the reset rotating counterweight presses down on the metal blocking bracket A and the metal blocking bracket B by its own weight, so that the two are in a downward vertical state. There is a metal blocking block below the vertical metal blocking bracket. When the operator is arranging the fabric to prepare for cutting, if a misoperation causes the cutting blade to fall prematurely, the cutting top box will drive the metal blocking bracket to fall a short distance. The metal blocking bracket will then be blocked by the metal blocking block and cannot move further down, thereby preventing the cutting top box and the cutting blade from falling further, providing the operator with sufficient time to pull their hands out and escape, and physically blocking the risk of the cutting blade accidentally injuring people.

[0018] Once the operator confirms their safety and is ready to cut, they simply pull the metal blocking bracket A or B forward to an angle greater than 30 degrees using the handle to start the hydraulic cylinder for cutting. Because the resistance sleeve applies resistance to the connecting shaft, the pulled metal blocking bracket will remain at this angle and will not immediately fall back due to the pressure of the reset rotating counterweight. Furthermore, the metal blocking bracket at this angle will not obstruct the descent of the cutting top box, allowing the cutting blade to smoothly complete the material cutting. The entire process requires no complex operations and is well-suited to efficient production schedules. After cutting, the reset rotating counterweight will continue to apply pressure to the metal blocking bracket, causing it to overcome the resistance sleeve and descend uniformly to a vertical position. Simultaneously, the hydraulic cylinder will lift the cutting top box upwards via the hydraulic axis to reset it. The metal blocking bracket will then further rotate to a vertical position and be limited by the metal blocking block. When preparing for the next material cutting, the device will automatically reset to its protective state, requiring no manual adjustment. This ensures a safety barrier before each operation and prevents potential safety hazards caused by forgetting to reset the protective structure. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figure 1-5The diagram illustrates a high-efficiency cutting device for producing plain polyester-cotton-linen fabric. It includes a main unit housing 1 and hydraulic cylinders fixed at approximately four corners within the housing. Each hydraulic cylinder is equipped with a hydraulic shaft 5. The four corner hydraulic cylinders provide uniform driving force from four directions, preventing uneven force distribution during cutting and ensuring cutting accuracy. A cutting top box 8 is located above the main unit housing 1. Fixed bearing seats 6 are welded to the bottom of both ends of the cutting top box 8. The tops of the multiple hydraulic shafts 5 are fixedly connected to the corresponding fixed bearing seats 6. When the hydraulic cylinders are activated, the hydraulic shafts 5 extend and retract, driving the cutting top box 8 up and down. By controlling the extension and retraction length of the hydraulic shafts 5, the descent height of the cutting top box 8 can be precisely adjusted to adapt to the cutting needs of plain polyester-cotton-linen fabrics with different stacking thicknesses, avoiding uneven force distribution during cutting. Insufficient cutting depth may result in the fabric not being cut, while excessive cutting depth may damage the device. A long strip-shaped blade holder 9 is horizontally fixed to the front side of the center of the bottom of the cutting top box 8. The front end of the blade holder is fixed with a cutting blade 13 by multiple screws. The screw fixing method allows for easy replacement of different types of cutting blades 13 according to cutting needs. The long strip-shaped blade holder 9 ensures that the cutting blade 13 is horizontally flat and fixed, avoiding the cutting blade 13 tilting and causing irregular cutting edges. It is suitable for the flatness requirements of polyester-cotton-linen plain weave fabric. A controller 12 is located at the center of the front end of the cutting top box 8. The controller 12 is electrically connected to the main unit box 1 of the device. The operator can set the cutting parameters and start or stop the cutting operation through the controller 12. There is no need to manually control the hydraulic cylinder, which improves the convenience of operation and cutting consistency. It is suitable for mass production of polyester-cotton-linen plain weave fabric.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, maintenance windows 10 are provided inside the top of the cutting top box 8 and inside the left and right ends of the main unit box 1. Protective plates 11 are fixed to the maintenance windows 10 with screws. The maintenance windows 10 facilitate the operator's inspection of the internal components, while the protective plates 11 prevent dust and fabric debris from entering the interior when not under maintenance, protecting the components' normal operation. The screw-fixed protective plates 11 are easy to remove and can be opened without complicated tools. Lifting protective covers 14 are provided on the top of the left and right ends of the main unit box 1. The two lifting protective covers 14 protect the left and right ends of the cutting top box 8, and the maximum upward movement height of the cutting top box 8 must be compatible with the height of the lifting protective covers 14. The lifting protective covers 14 prevent external foreign objects from being drawn into the gap between the cutting top box 8 and the main unit box 1 during the lifting and lowering process of the cutting top box 8, while also preventing the operator from accidentally activating the lifting covers. The components enhance device safety. The height-adaptive design ensures that the cutting top box 8 is not obstructed by the protective cover when it is raised or lowered, thus not affecting normal cutting. The main unit box 1 has mounting rails 2 on both the left and right sides of the front center. The mounting rails 2 are flush with the outer wall of the top of the main unit box 1. Stacking plates 3 are placed on the mounting rails 2 and the outer wall of the top of the main unit box 1. The stacking plates 3 are used to place the plain weave polyester-cotton-linen fabric to be cut. The flush design ensures that the plates are placed stably, avoiding the fabric tilting and causing the cutting position to shift. The mounting rails 2 make it easy for the operator to push the stacking plates 3 to adjust their position to adapt to different cutting size requirements. The top of the front end of the stacking plates 3 has a push-pull adjustment handle 4. The operator can easily push the plates with the handle without directly contacting the fabric, avoiding wrinkles caused by hand contact, ensuring cutting accuracy, and improving operating efficiency.

[0028] like Figure 1 , Figure 4 and Figure 5As shown, a personal safety protection device 7 is provided at the front end of the top of the cutting top box 8. The personal safety protection device 7 includes a metal fixing sleeve 20 and a U-shaped corner sleeve 19. The metal fixing sleeve 20 is fitted onto the top corner of the front end of the cutting top box 8, and the two are fixedly connected by welding. The welding fixation ensures that the metal fixing sleeve 20 fits tightly with the cutting top box 8, preventing the protection device from loosening during the lifting and lowering of the cutting top box 8. U-shaped corner sleeves 19 are welded to both ends of the metal fixing sleeve 20 and on the outer wall of the front end. The U-shaped opening of the U-shaped corner sleeve 19 faces forward, providing installation support for subsequent components. The personal safety protection device 7 also includes a metal blocking bracket A18, a metal blocking bracket B23, and a connecting shaft 21. The metal blocking bracket A18 and the metal blocking bracket B23 are symmetrically arranged on the left and right sides, and their top ends are respectively inserted into the two U-shaped corner sleeves 19, and are connected to the U-shaped corner sleeves 19 by the connecting shaft 21. The device includes a 9-way connection. The connecting shaft 21 passes through the metal blocking bracket A18, the metal blocking bracket B23, and the two U-shaped corner sleeves 19. The connecting shaft 21 is fixedly connected to the metal blocking bracket A18 and the metal blocking bracket B23 by welding. This connection method allows the metal blocking bracket A18 and the metal blocking bracket B23 to move synchronously. That is, when the metal blocking bracket A18 or the metal blocking bracket B23 rotates alone, it will drive the other bracket to rotate synchronously through the connecting shaft 21, ensuring that the protection status is consistent. The device also includes two resistance sleeves 22. The two resistance sleeves 22 are welded to the outer wall of one side of the two U-shaped corner sleeves 19 in opposite directions, and both are sleeved outside the connecting shaft 21. When the metal blocking bracket A18 and the metal blocking bracket B23 stop rotating, the resistance sleeves 22 will apply resistance to the connecting shaft 21 to prevent it from rotating arbitrarily, ensuring that the bracket can be stably maintained at the set angle.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, the personal safety protection device 7 also includes a metal blocking block 15, a reset rotating counterweight 16, and an opening handle 17. When both the metal blocking bracket A18 and the metal blocking bracket B23 are in a downward vertical state, a reset rotating counterweight 16 is welded to the outer wall near the bottom front end of both. The reset rotating counterweight 16 applies downward pressure to the bracket by its own weight, keeping the bracket in a vertical state. An opening handle 17 is provided above both reset rotating counterweights 16, making it convenient for the operator to pull the bracket to rotate. The downward vertical metal blocking bracket A18 and the metal blocking bracket B23 are in a vertical state. Below B23, there are metal blocking blocks 15 fixed to the outer wall of the front end of the main unit box 1. The metal blocking blocks 15 can apply a limiting force by contacting the bracket, which helps the bracket resist the resistance of the resistance sleeve 22 and maintain a stable vertical state. When the cutting blade 13 is in the uncutting reset state, the distance between the bottom end of the vertical metal blocking bracket A18 and the metal blocking bracket B23 and the top end of the metal blocking block 15 is equal to the vertical height of the metal blocking block 15. This size matching can ensure that the bracket can rotate to the vertical state without obstruction and avoid the bracket from being unable to reset due to size deviation.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, the usage cycle of the personal safety protection device 7 is as follows: When the cutting device is not in operation, the reset rotating counterweight 16 applies downward pressure to the metal blocking brackets A18 and B23 by its own weight, so that they overcome the resistance of the resistance sleeve 22 and remain in a downward vertical state. The bottom end of the metal blocking bracket is opposite to the metal blocking block 15 at the front end of the main unit box 1, forming a safety barrier. When the operator needs to perform cutting operations, he holds the opening handle 17 and pulls the metal blocking bracket A18 or metal blocking bracket B23 forward. Since the two are synchronously connected by the connecting shaft 21, they will rotate forward together to an angle greater than 30 degrees. At this time, the resistance sleeve 22 applies resistance to the connecting shaft 21. Although the reset rotating counterweight 16 can rotate downward and reset under the pressure of its weight, the downward rotation reset speed is relatively slow, which is sufficient for the cutting blade 13 to complete the cutting of the polyester-cotton fabric. The plain linen fabric is cut, and then the operator starts the device through the controller 12. The hydraulic cylinder drives the hydraulic shaft 5 to lower the cutting top box 8, and the cutting blade 13 moves down to complete the cutting of the polyester-cotton-linen plain linen fabric. During this process, the metal blocking bracket does not obstruct the movement of the cutting top box 8. After the cutting is completed, the hydraulic cylinder drives the cutting top box 8 to reset upward. During the cutting process, the reset rotating counterweight 16 continuously applies pressure. The metal blocking bracket overcomes the resistance of the resistance sleeve 22 by the weight of the counterweight and rotates downward at a uniform speed. When the rear end of the metal blocking bracket contacts the metal blocking block 15, it will not obstruct the normal descent of the cutting top box 8 in this state. After the cutting top box 8 is completely reset upward, it will drive the metal blocking bracket to rise at the same time and separate from the metal blocking block 15. Then the metal blocking bracket continues to reset and rotate, and finally returns to the initial protective state of downward verticality, waiting for the next cutting cycle.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
