AI Technical Summary
当前，市面上主流的裁布机在实际应用过程中，虽能实现对防护服布料的裁切作业，但在裁切后的物料处理环节仍存在不足之处，具体而言，现有裁布机在完成布料裁切后，通常需要人工操作来完成废料的去除工作；操作人手动将裁切平台上残留的废料逐一清理，随后再对裁切完成的防护服裁片样品进行收集整理，这一过程显著增加了操作人员的劳动强度，导致防护服生产的整体效率降低；此外，在人工去除废料的操作过程中，由于废料与裁切好的防护服裁片样品往往紧密贴合在同一放置平台上，操作人员在清理废料时，容易将已裁切完成的样品带起使其移位，影响裁片样品的收集效率
通过下料组件与推板、收集箱的设计，实现了废料的自动推出与收集。裁切完成后，电机驱动齿形带运转，带动齿柱、齿条联动，使推板将放置板上的废料推出，最终落入收集箱，无需操作人员手动逐一清理废料，彻底省去人工清理环节，显著降低操作人员劳动强度，提升裁布作业的整体效率。

Description
Technical Field
[0001] This utility model relates to the field of medical supplies production equipment technology, and in particular to a fabric cutting device for the production of protective clothing. Background Technology
[0002] In the medical and health field, protective clothing is a key piece of equipment to protect the life safety and health of personnel, and its market demand continues to rise. This also puts forward more stringent requirements for the production efficiency and product quality of protective clothing. As one of the core links in the production process of protective clothing, the efficiency and cutting accuracy of the fabric cutting process directly determine the smoothness of the subsequent sewing process and the final quality of the protective clothing. Currently, while mainstream fabric cutting machines on the market can cut protective clothing fabrics, they still have shortcomings in the post-cutting material handling process. Specifically, after cutting the fabric, existing fabric cutting machines typically require manual operation to remove waste. Operators manually clean up the waste remaining on the cutting platform one by one, and then collect and organize the cut protective clothing samples. This process significantly increases the labor intensity of operators, leading to a decrease in the overall efficiency of protective clothing production. In addition, during the manual waste removal process, because the waste and the cut protective clothing samples are often closely attached to the same placement platform, operators may easily lift and displace the cut samples while cleaning up the waste, affecting the efficiency of sample collection.
[0003] Therefore, it is necessary to provide a new fabric cutting device for the production of protective clothing to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fabric cutting device for the production of protective clothing.
[0005] The fabric cutting device for protective clothing production provided by this utility model includes: a fabric cutting machine body, a placement plate, a clamping plate, a pusher plate, and a feeding assembly. The fabric cutting machine body is equipped with a guide frame for conveying fabric. A placement plate is placed on the top of one end of the guide frame that extends out of the fabric cutting machine body. A support plate is installed inside the placement plate. Clamping plates for fixing the fabric to be cut are arranged at equal intervals inside the placement plate. Pusher plates are arranged at equal intervals below the placement plate. The feeding assembly is installed inside the guide frame. The feeding assembly drives the pusher plate to move, pushing out and collecting the waste material on the placement plate.
[0006] Preferably, the placement plate has symmetrically opened mounting grooves inside, and springs are fixedly connected to the inner walls of the mounting grooves. The other end of each spring is fixedly connected to a locking block. The side walls of the support plate have symmetrically opened locking slots, and the locking blocks engage with the corresponding locking slots. The bottom of the support plate has symmetrically fixedly connected trapezoidal blocks corresponding to the locking blocks.
[0007] Preferably, the guide frame is symmetrically fixedly connected with guide rods inside, and the support plate is symmetrically fixedly connected with connecting rods on both sides. The other end of each connecting rod is sleeved on the outer wall of the corresponding guide rod and is slidably connected to its outer wall.
[0008] Preferably, guide rods are symmetrically fixedly connected to the bottom of the placement plate, and electric push rods are symmetrically fixedly connected to the inside of the guide frame. The output end of each electric push rod is fixedly connected to a guide sleeve, and the guide sleeve is coaxial with the corresponding guide rod.
[0009] Preferably, the feeding assembly includes: a motor, a toothed belt, toothed columns, and a rack. The motor is fixedly connected inside the guide frame, and the toothed belt is rotatably connected inside the guide frame. The toothed belt has a square design. The output end of the motor is fixedly connected to one of the transmission shafts inside the toothed belt. The toothed columns corresponding to the four sides of the toothed belt are rotatably connected inside the guide frame, and the toothed columns are all engaged with the toothed belt. The side walls of the toothed columns are all engaged with racks. The racks are located below the toothed belt and are slidably connected to the inner wall of the guide frame. The ends of the racks are all fixedly connected to connecting frames, and the ends of the connecting frames are all fixedly connected to corresponding push plates.
[0010] Preferably, the top of the placement plate is provided with equidistant grooves around the perimeter, and each groove is rotatably connected to a sleeve. Each sleeve is fixedly connected to a tension spring on its inner wall, and the other end of each tension spring is fixedly connected to a telescopic rod. The telescopic rod is slidably connected to the inner wall of the corresponding sleeve, and the other end of each telescopic rod is rotatably connected to the corresponding clamping plate. Each rotatable connection is equipped with a torsion spring.
[0011] Preferably, a collection box is placed at the bottom of the placement plate.
[0012] Compared with related technologies, the fabric cutting device for protective clothing production provided by this utility model has the following beneficial effects: The design of the feeding assembly, push plate, and collection box enables automatic ejection and collection of waste materials. After cutting, the motor drives the toothed belt to rotate, which in turn drives the toothed column and rack to push the waste material on the plate out and finally into the collection box. This eliminates the need for operators to manually clean up the waste material one by one, completely eliminating the manual cleaning process, significantly reducing the labor intensity of operators, and improving the overall efficiency of the fabric cutting operation.
[0013] The electric push rod drives the placement plate to descend below the push plate, so that the push plate only contacts and pushes out the waste material, while the cut pieces are left on the support plate for the operator to remove. This completely avoids interference with the cut pieces during the waste material handling process and further ensures the quality of the cut pieces. Attached Figure Description

[0019] It should be noted that the electric push rod 14 is an existing mature device. In the initial state, its output end is in the extended state, and the guide sleeve 15 fixed at its output end is coaxial with the guide rod 13 fixed at the bottom of the placement plate 3.
[0020] Please see Figure 4 , Figure 5 and Figure 6The feeding assembly includes: a motor 16, a toothed belt 17, toothed posts 18, and a rack 19. The motor 16 is fixedly connected inside the guide frame 2. The toothed belt 17, which is square, is rotatably connected inside the guide frame 2. The output end of the motor 16 is fixedly connected to one of the drive shafts inside the toothed belt 17. The toothed posts 18, corresponding to the four sides of the toothed belt 17, are rotatably connected inside the guide frame 2, and all four posts 18 mesh with the toothed belt 17. The side walls of the toothed posts 18 are all meshed with racks 19, which are located below the toothed belt 17 and slide against the inner wall of the guide frame 2. The rack 19 is connected to a connecting frame at its end, and the end of the connecting frame is fixedly connected to the corresponding push plate 6. The top of the placement plate 3 is provided with equidistant mating grooves, and the inside of each mating groove is rotatably connected to a sleeve 20. The inner wall of each sleeve 20 is fixedly connected to a tension spring 21, and the other end of each tension spring 21 is fixedly connected to a telescopic rod 22. The telescopic rod 22 is slidably connected to the inner wall of the corresponding sleeve 20. The other end of each telescopic rod 22 is rotatably connected to the corresponding clamping plate 5, and a torsion spring is installed at each of its rotatable connections. A collection box 23 is placed at the bottom of the placement plate 3.
[0021] It should be noted that motor 16 is a forward and reverse motor, which is a mature existing equipment.
[0022] The working principle of the fabric cutting device for protective clothing production provided by this utility model is as follows: First, neatly stack the protective clothing fabric to be cut on the placement plate 3. Then, rotate the sleeve 20 until it is perpendicular to the placement plate 3. At this point, the sleeve 20 is completely disengaged from the mating groove. The torsion spring at the rotation connection of the clamping plate 5, which is rotatably connected to the sleeve 20 via the telescopic rod 22, loses its external constraint and begins to release its elastic potential energy. This pushes the clamping plate 5 to rotate around the rotation point of the telescopic rod 22, eventually making the clamping plate 5 parallel to the placement plate 3. The operator pulls the clamping plate 5 upwards, which simultaneously causes the telescopic rod 22 to slide upwards along the inner wall of the sleeve 20. During this process, the tension spring fixedly connected inside the sleeve 20... 21 is gradually stretched to store elastic potential energy; the clamping plate 5 is continuously pulled until the distance between the clamping plate 5 and the placement plate 3 is greater than the thickness of the stacked fabric. Then, the edge of the stacked fabric is placed under the clamping plate 5, and the clamping plate 5 is slowly released. The tension spring 21 releases the stored elastic potential energy and pulls the telescopic rod 22 to slide down along the inner wall of the sleeve 20, thereby driving the clamping plate 5 to move down synchronously until the clamping plate 5 is pressed against the surface of the fabric. The above operation is repeated to clamp the fabric with all the clamping plates 5 corresponding to the matching grooves around the placement plate 3, so that the fabric is evenly stressed around the perimeter and to prevent the fabric from shifting during subsequent feeding and cutting. Next, the placement plate 3 is pushed into the interior of the fabric cutting machine body 1. At this time, the connecting rods 12 symmetrically fixed on both sides of the support plate 4 installed inside the placement plate 3 will slide smoothly along the axial direction of the guide rods 11 symmetrically fixed inside the guide frame 2. The guide rods 11 play a precise guiding and limiting role for the connecting rods 12, preventing the connecting rods 12 from wobbling radially during the sliding process, thereby ensuring that the placement plate 3 always moves into the interior of the fabric cutting machine body 1 in a straight line. During the process of pushing the placement plate 3, the guide rods 13 symmetrically fixedly connected to the bottom of the placement plate 3 will gradually be pulled out from the guide sleeve 15 fixedly connected to the output end of the electric push rod 14 inside the guide frame 2; as the placement plate 3 continues to push, when the placement plate 3 drives the fabric fixed on it to completely enter the cutting work area inside the fabric cutting machine body 1, the pushing action stops; the fabric cutting machine body 1 is started, and the cutting component inside the fabric cutting machine body 1 begins to cut the fabric fixed on the placement plate 3 according to the preset size and shape of the protective clothing cut pieces; After the cutting operation is completed, pull the placement plate 3 in the opposite direction so that the placement plate 3 carries the cut pieces and waste materials out of the cutting area of the fabric cutting machine body 1. During this process, the guide rod 13 at the bottom of the placement plate 3 will gradually approach the guide sleeve 15 and accurately insert into the guide sleeve 15. At this time, the placement plate 3 is in a stable static state, ready for subsequent waste material cleaning. When the electric push rod 14 is activated, its output end begins to retract downwards, causing the guide sleeve 15 to move downwards synchronously. Since the guide rod 13 is now fully inserted into the guide sleeve 15, the guide sleeve 15 moves downwards, causing the placement plate 3 to move downwards along with it via the guide rod 13. During the downward movement of the placement plate 3, the inner wall of the symmetrically opened slots 9 on the side wall of the support plate 4 will exert a squeezing force on the end of the locking block 8 in the mounting groove inside the placement plate 3. Under the action of the squeezing force, the locking block 8 will move into the mounting groove, compressing the spring 7. As the placement plate 3 continues to move downwards, when the locking block 8 is completely disengaged from the slot 9, the spring 7 releases its elastic force, pushing the locking block 8 back to its initial position. The placement plate 3 continues to move downwards under the drive of the electric push rod 14 until the upper surface of the placement plate 3 is lower than the initial position of the push plate 6. At this time, the electric push rod 14 stops running. Under the action of the clamping plate 5, the waste material moves downwards with the placement plate 3, while the cut sample remains on the support plate 4, achieving separation between the two. The operator can then remove the separated cut sample. At the same time, the motor 16 starts to run, and its output end is fixedly connected to one of the drive shafts inside the toothed belt 17. Therefore, the rotation of the motor 16 will cause the toothed belt 17 to run. Since the toothed belt 17 adopts a square design and its four sides are respectively meshed with the four toothed columns 18 rotatably connected inside the guide frame 2, the toothed belt 17 will drive the four toothed columns 18 to rotate synchronously around their own rotation axis when it runs. The side wall of each toothed column 18 is meshed with the corresponding rack 19, so that the rack 19 slides horizontally along the inner wall of the guide frame 2. The rack 19 is located below the toothed belt 17 and is slidably connected to the inner wall of the guide frame 2 to ensure that the rack 19 can slide stably. Each end of the rack 19 is fixedly connected to a connecting frame, and the other end of the connecting frame is fixedly connected to the corresponding push plate 6. Therefore, the sliding of the rack 19 will drive the push plate 6 to move synchronously through the connecting frame. During the movement, the end face of the push plate 6 will come into contact with the waste on the placement plate 3 and generate a horizontal pushing force on the waste, pushing the waste off the placement plate 3. The ejected waste material eventually falls into the collection box 23 pre-placed at the bottom of the placement plate 3, realizing automatic waste collection. During this process, there is no need for operators to manually clean up the waste material, which not only reduces the labor intensity of operators, but also avoids the interference that manual cleaning may cause to the cut pieces. After the waste material is completely pushed out of the placement plate 3, the tension spring 21 inside the sleeve 20 continues to release the remaining elastic potential energy, pulling the telescopic rod 22 to further retract along the inner wall of the sleeve 20, so that the telescopic rod 22 returns to its initial length; the motor 16 is started to reverse, and the toothed belt 17 also reverses; when the toothed belt 17 reverses, it drives the toothed column 18 to rotate in the opposite direction through meshing with the toothed column 18, and the toothed column 18 then drives the toothed column 19 to slide in the opposite direction along the inner wall of the guide frame 2 through meshing with the rack 19; the rack 19 drives the push plate 6 to move in the opposite direction synchronously through the connecting frame until the push plate 6 returns to the initial position. At this time, the motor 16 stops running, the push plate 6 stops moving, and the reset is completed; then, the electric push rod 14 is started, and its output end begins to extend upward, driving the guide sleeve 15 to move upward synchronously. The guide sleeve 15 drives the placement plate 3 to move upward through the guide rod 13 to perform the reset operation; As the placement plate 3 moves upward, the end of the locking block 8 inside the mounting groove of the placement plate 3 gradually comes into contact with the inclined surface of the trapezoidal block 10 symmetrically fixed to the bottom of the support plate 4. As the placement plate 3 continues to rise, the inclined surface of the trapezoidal block 10 exerts a squeezing force on the locking block 8 along the inclined surface direction. Under the action of this squeezing force, the locking block 8 moves into the mounting groove and compresses the spring 7 again. When the placement plate 3 rises to the initial position, the locking block 8 moves exactly to the position corresponding to the locking groove 9 on the side wall of the support plate 4. At this time, the spring 7 releases the elastic potential energy stored during compression, pushing the locking block 8 to move out of the mounting groove, so that the locking block 8 can be smoothly locked into the locking groove 9, realizing the re-locking and fixing of the placement plate 3 and the support plate 4. At this time, the fabric to be cut can be placed again, ready for the next round of cutting work.
