Description

Technical Field

[0001] This invention relates to the technical field of fabric cutting, and in particular to a cutting device and process for producing a sports protective abdominal belt. Background Technology

[0002] The raw materials for abdominal binders need to be cut because they are mostly rolls or large pieces of fabric. Abdominal binder materials often contain elastic fabrics and knitted fabrics, which are easily stretched or misaligned when subjected to external forces during cutting. If they are not fixed, the cut edges are easily skewed, the dimensional accuracy is out of control, and the finished product does not meet the specifications.

[0003] However, in existing technologies, during the fabric feeding process via conveyor belts, the lack of external constraints makes the fabric prone to wrinkles due to uneven weight distribution and slight vibrations from the conveyor belt. This not only affects the accuracy of subsequent processing steps but can also damage the fabric, reducing production quality and efficiency. To address this issue, a common approach is to use a centrifugal fan in conjunction with a vacuum adsorption chamber. This uses vacuum suction to smoothly adhere the fabric to the conveyor belt, eliminating wrinkles. However, the vacuum adsorption chambers currently used have significant design limitations. The size of the vacuum adsorption area is fixed and cannot be dynamically adjusted based on the actual coverage area of ​​the fabric on the conveyor belt. On one hand, when the area of ​​the fabric on the conveyor belt is smaller than the adsorption area of ​​the vacuum adsorption chamber, some adsorption areas will be uncovered. Since the adsorption area cannot be flexibly switched, these uncovered areas will continue to generate vacuum suction, requiring the centrifugal fan to continuously provide suction power to these ineffective areas. This power output does not contribute to fabric adsorption. In practice, this is purely a meaningless consumption of energy. Long-term operation will significantly increase the energy consumption cost of production, which contradicts the energy conservation and consumption reduction concept advocated in current industrial production. On the other hand, the continuous operation of the ineffective adsorption area will cause the vacuum suction to disperse. The total suction of the vacuum adsorption system is relatively fixed. When part of the suction is used in areas without fabric, the effective suction in areas covered by fabric will be weakened. This effect of suction dispersion is more obvious when conveying fabric at the edges or in small areas. It may cause the fabric to be unable to be firmly adsorbed, resulting in wrinkles again during the conveying process, or even deviation and slippage. This defeats the original purpose of vacuum adsorption, failing to ensure the flat conveying of the fabric and causing waste. Summary of the Invention

[0004] The purpose of this invention is to provide a sports protective abdominal belt, cutting equipment and process for abdominal belt production, to solve the problem of not being able to effectively use adsorption force to fix the fabric.

[0005] This invention proposes a sports protective abdominal belt cutting device, comprising a machine body, a support roller fixedly connected to the top of the machine body, a receiving roller rotatably connected to one side of the machine body, a limiter located above the machine body and near the receiving roller, two limit plates symmetrical about the central axis of the machine body, multiple cutters equidistantly arranged and fixedly connected to the outside of the support roller, a straight plate fixedly connected to the machine body, an adsorbent located inside the machine body, multiple separators equidistantly arranged and located within the straight plate, and a guide roller rotatably connected to the other side of the machine body. The central axis of the limiter coincides with the central axis of the machine body. The straight plate is located directly below the cutters. The adsorbent is located below the straight plate and its output end communicates with the inside of the straight plate. When the separators are squeezed and moved downwards, the output end of the adsorbent communicates with the top of the straight plate.

[0006] Furthermore, side plates are provided at the top of both ends of the straight plate, and a protrusion is provided at the top of the side of the straight plate away from the blade. Multiple guide rods are fixedly connected inside the straight plate, and a vertical slot is opened inside the straight plate. The separator is located inside the vertical slot, and the output end of the adsorber is connected to the vertical slot.

[0007] Furthermore, the separator includes a hollow block slidably connected in the vertical slot, a horizontal plate fixedly connected to one side of the hollow block, and a spring connected between the horizontal plate and the vertical plate. The horizontal plate is slidably connected to the outside of two guide rods. When the spring is not deformed, one side of the hollow block is in contact with the protrusion.

[0008] Furthermore, the upper part of the hollow block is divided into an arc surface and a slope, and the cutter does not contact the hollow block.

[0009] Furthermore, when the spring is not deformed, the inclined surface of the hollow block is located outside the vertical groove, and the vertical length of the inclined surface is greater than the length of the contact surface between the protrusion and the hollow block.

[0010] Furthermore, the cutter includes a support frame fixedly connected to the outside of the support roller, a ring rotatably connected to the outside of the support frame, a telescopic rod whose top end is rotatably connected to the top end of the support frame, a tripod fixedly connected to the outside of the ring, and a blade fixedly connected to the end of the tripod away from the ring. The ring and the support roller are concentric, and the output end of the telescopic rod is rotatably connected to the tripod.

[0011] Furthermore, only the hollow block located at the end is in contact with the side plate, the spring force coefficient is low, and when the top surface of the horizontal plate is in contact with the side plate, the top surface of the hollow block is not higher than the top surface of the side plate.

[0012] Furthermore, rollers are rotatably connected to both sides of the bottom end of the limiter, and a limit rod is fixedly connected to the machine body, with the limit rod being fixedly connected to two limit plates.

[0013] Another aspect of the present invention provides: a sports protective abdominal belt, manufactured by a sports protective abdominal belt cutting device, comprising a strip, one end of the strip being provided with a pressure buckle, and metal pieces being provided on both sides of the pressure buckle, the other end of the strip being provided with a lock buckle, and two magnetic pieces being fixedly connected to both sides of the lock buckle, the metal pieces being the same size as the magnetic pieces.

[0014] This invention also provides: a cutting process for a sports protective abdominal belt, using a sports protective abdominal belt cutting device, comprising the following steps: Fabric laying specifications: The fabric is laid around the outside of the receiving roller, the number of layers is controlled, and the top of the fabric is fixed with limiters and limit plates to prevent the fabric from shifting. Cutting operation: Simultaneously adjust the position of the cutter, and use the dividers and suction cups to further fix the bottom of the fabric.

[0015] Quality verification: After cutting with a cutting tool, check the size deviation, edge smoothness, and test the consistency of fabric elasticity.

[0016] The beneficial effects of this invention are: 1. On-demand adsorption is achieved through multiple separators. The separators can seal the adsorption ports. When the fabric covers the surface of the plate, the fabric's own weight, tensile tension, and the action of the guide roller above will squeeze the top of the separators, causing the separators to move down and open the corresponding number of adsorption ports. Different sizes of fabric squeeze different numbers of separators, and thus different numbers of adsorption ports are opened. This avoids ineffective air suction in areas without fabric, reduces energy waste, and concentrates the suction power, enhancing the adsorption effect on elastic fabrics and making adsorption more efficient.

[0017] 2. By achieving precise cutting, the synergistic effect of multiple positioning and dynamic adsorption ensures the stability of the abdominal belt raw material during the cutting process. The limiter and limit plate form a dual positioning system. The central axis of the limiter coincides with the central axis of the machine body. Combined with the limit plate, whose position can be adjusted via the limit rod, it provides precise auxiliary positioning of the fabric. In addition, the side plates at both ends of the straight plate further limit the fabric on both sides when it is large, effectively preventing the fabric from shifting due to conveying inertia or elastic deformation, avoiding cutting misalignment caused by edge deviation, and ensuring accurate dimensions of the cut abdominal belt blank.

[0018] 3. By meeting the cutting requirements of abdominal belt materials of different sizes and models, the limiting piece is symmetrical about the central axis of the machine body and its position is adjustable, which can adapt to the width of different models of abdominal belts. The dynamic adjustment of the adsorption area of ​​the separator can open the corresponding number of adsorption ports according to the size of the fabric, without the need to change equipment or make complex adjustments, thus improving the versatility and efficiency of the equipment.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-8This invention provides a sports protective abdominal belt cutting device, comprising a body 1, a support roller 2 fixedly connected to the top of the body 1, a receiving roller 3 rotatably connected to one side of the body 1, a limiter 4 positioned above the body 1 and near the receiving roller 3, two limit plates 5 symmetrically arranged about the central axis of the body 1, multiple cutters 6 equidistantly arranged and fixedly connected to the outside of the support roller 2, a straight plate 7 fixedly connected to the body 1, an adsorbent 8 disposed inside the body 1, multiple separators 9 equidistantly arranged and located within the straight plate 7, and a guide roller 10 rotatably connected to the other side of the body 1. The central axis of the limiter 4 coincides with the central axis of the machine body 1. The straight plate 7 is located directly below the cutter 6. The suction device 8 is located below the straight plate 7 and its output end is connected to the inside of the straight plate 7. After the separator 9 is squeezed and moved down, the output end of the suction device 8 is connected to the top of the straight plate 7. Since there are multiple separators 9, and the separators 9 close the suction port, the suction port will open after the separators 9 move down. Different sizes of fabrics are squeezed by different numbers of separators 9, and thus the number of suction ports opened is different. Therefore, it can be suctioned according to the needs of different sizes of fabrics. At the same time, it works with the limiter 4 and the limit piece 5 for auxiliary positioning to achieve dual positioning.

[0023] Specifically, the guide roller 10 squeezes the fabric, while the collecting roller 3 collects the cut fabric. The adsorber 8 uses a variable frequency centrifugal fan, located below the straight plate 7, and is connected to the inside of the straight plate 7 through a pipe to provide negative pressure for adsorption. The separator 9 can close a single adsorption unit. When the fabric covers the surface of the straight plate 7, the fabric's own weight and tensile tension, along with the upper guide roller 10, squeeze the top of the separator 9, opening the adsorption port of the unit and forming a negative pressure passage with the adsorber 8, realizing dynamic adjustment of the adsorption area, adsorption on demand, and concentrated suction.

[0024] Reference Figures 1-8 The top of both ends of the straight plate 7 is provided with side plates 71, so that when the fabric is large, the side plates 71 can be used to limit the sides. The top of the side of the straight plate 7 away from the blade 65 is provided with a protrusion 72. Multiple guide rods 73 are fixedly connected inside the straight plate 7. The straight plate 7 has a vertical slot 701 inside. The separator 9 is located inside the vertical slot 701, thereby closing the vertical slot 701. The output end of the adsorber 8 is interconnected with the vertical slot 701, so that the adsorber 8 can be used for adsorption.

[0025] Specifically, the side plate 71 and the limiting piece 5 form a double lateral limiting. The spacing of the limiting piece 5 is adjustable to adapt to different widths. The side plate 71 serves as a fixed boundary to prevent the fabric from exceeding the range of the limiting piece due to conveying inertia or elastic deformation, thus avoiding cutting misalignment caused by edge deviation. The separator 9 needs to move down and open along the vertical groove 701 under the pressure of the fabric. The guide rod 73 can limit the lateral sway of the separator 9, ensuring that it only makes stable vertical movements. The separator 9 is embedded in the groove to form a seal. The output end of the adsorber 8 is directly connected to the vertical groove 701, forming the adsorption area of ​​the separator 9, which can adsorb the airflow channel of the fabric. This integrates the dispersed adsorption holes into a concentrated airflow channel, reducing the diffusion loss of negative pressure inside the straight plate 7, and making the suction of the adsorber 8 act more directly on the fabric contact area, enhancing the gripping force on elastic fabrics.

[0026] Reference Figures 1-7 The separator 9 includes a hollow block 91 slidably connected in the vertical slot 701, a horizontal plate 92 fixedly connected to one side of the hollow block 91, and a spring 93 connected between the horizontal plate 92 and the vertical plate 7. The horizontal plate 92 is slidably connected to the outside of two guide rods 73, which guide and limit the horizontal plate 92. When the spring 93 is not deformed, one side of the hollow block 91 is in contact with the protrusion 72, thereby closing the top of the vertical slot 701. When the hollow block 91 moves down and one side is no longer in contact with the protrusion 72, the spring 93 is compressed, and the hollow block 91 and the vertical plate 7 are intersected, creating a gap. This allows the output end of the absorber 8 to communicate with the top of the vertical plate 7. The fabric is located above the vertical plate 7 and can squeeze the hollow block 91, so the absorber 8 will directly absorb the fabric.

[0027] Specifically, the hollow block 91 is hollow inside to reduce its weight. When the fabric is conveyed to the top of the straight plate 7 and comes into contact with the top of the hollow block 91, the weight of the fabric or the conveying tension exerts downward pressure on the hollow block 91. This pressure overcomes the elasticity of the spring 93 and pushes the hollow block 91 down along the vertical slot 701. At the same time, the horizontal plate 92 slides down along the two guide rods 73, and the spring 93 is compressed. As the hollow block 91 moves down, its contact with the protrusion 72 is released, and the top side forms an interlaced gap with the upper surface of the straight plate 7. At this time, the vertical slot 701 is connected to the top of the straight plate 7 through this gap. The negative pressure generated by the adsorber 8 acts directly on the bottom surface of the fabric through the vertical slot 701, the interior of the hollow block 91 and the gap, achieving precise adsorption of the fabric. The elasticity of the spring 93 can be preset according to the weight and elasticity of common fabrics, usually 5 to 10 N. For thin fabrics, slight pressure can trigger the opening.

[0028] Reference Figures 2-7The upper part of the hollow block 91 is divided into an arc surface 901 and an inclined surface 902. The cutter 6 does not contact the hollow block 91, thereby avoiding damage to the parts by collision. When the spring 93 is not deformed, the inclined surface 902 of the hollow block 91 is located outside the vertical slot 701. The vertical length of the inclined surface 902 is greater than the length of the contact surface between the protrusion 72 and the hollow block 91.

[0029] Specifically, the vertical length of the inclined surface 902 is the length from its bottom end to the top surface of the hollow block 91. When the fabric squeezes the hollow block 91, it will squeeze the top surface of the hollow block 91 to overlap with the top surface of the straight plate 7. Then the length of the hollow block 91 moving down is equal to the vertical length of the inclined surface 902. Therefore, the length of the downward movement is greater than the length of the contact surface between the protrusion 72 and the hollow block 91, so that the two no longer contact each other and form an interlocking structure for adsorption.

[0030] Reference Figures 2-6 The cutter 6 includes a support frame 61 fixedly connected to the outside of the support roller 2, a ring 62 rotatably connected to the outside of the support frame 61, a telescopic rod 63 whose top end is rotatably connected to the top end of the support frame 61, a tripod 64 fixedly connected to the outside of the ring 62, and a blade 65 fixedly connected to the end of the tripod 64 away from the ring 62. The ring 62 and the support roller 2 are concentric, and the output end of the telescopic rod 63 is rotatably connected to the tripod 64.

[0031] Specifically, when replacing the blade 65, the telescopic rod 63 can be retracted to pull the tripod 64, thereby causing the fixedly connected ring 62 to rotate around the center of the support roller 2, thus moving the blade 65 upward for quick replacement.

[0032] Reference Figures 2-6 The hollow block 91 located at the end is attached to the side plate 71 to strengthen the constraint on the edge of the fabric. The spring 93 has a low elastic coefficient to ensure that the fabric can quickly squeeze the hollow block 91. When the top surface of the horizontal plate 92 is attached to the side plate 71, the top surface of the hollow block 91 is not higher than the top surface of the side plate 71 to prevent the fabric from shifting beyond the side plate 71.

[0033] Specifically, when the spring 93 is not compressed by external force, its elasticity pushes the horizontal plate 92 to slide upward along the guide rod 73, causing the hollow block 91 to move to the highest point. At this time, the end hollow block 91 is tightly fitted with the inner side of the side plate 71, forming a seal with the protrusion 72. The top opening of the vertical slot 701 is completely closed, and the negative pressure generated by the absorber 8 is restricted inside the vertical slot 701. At the same time, the top surface of the horizontal plate 92 is fitted with the bottom of the side plate 71, and the top surface of the hollow block 91 is flush with the top surface of the side plate 71, avoiding the formation of protrusions that hinder the fabric conveying.

[0034] Reference Figures 1-8Both sides of the bottom end of the limiter 4 are rotatably connected to rollers 41. The double rollers 41 are used to push the fabric upwards. One end of the limiter 4 is rotatably connected to the machine body 1, so that the rollers 41 change with the thickness of the fabric. The machine body 1 is fixedly connected to a limit rod 101, which is fixedly connected to two limit pieces 5. The position of the two limit pieces 5 can be changed by adjusting the limit rod 101.

[0035] The working principle of this invention is as follows: The abdominal binder raw material roll is introduced into the equipment via guide roller 10. Guide roller 10 forms initial compression on the fabric to ensure that the fabric is flat and enters the subsequent process. When the fabric is conveyed above the straight plate 7, it first contacts the protrusion 72 on the top of the side of the straight plate 7 away from the blade 65. The protrusion 72 prevents the front end of the fabric from sliding, providing a clear feed baseline for the fabric and ensuring that the starting position of each section of fabric is consistent. At the same time, the side plates 71 at both ends of the straight plate 7 and the limiting piece 5 form a double lateral limiting. The side plates 71 serve as fixed boundaries to prevent the fabric from exceeding the limiting range due to conveying inertia or elastic deformation, effectively avoiding edge deviation. The separator 9 located in the vertical slot 701 inside the straight plate 7 is in its initial state. The spring 93 is not deformed. One side of the hollow block 91 is in contact with the protrusion 72, and only the end of the hollow block 91 is in contact with the side plate 71, sealing the top of the vertical slot 701. The single adsorption unit is in a sealed state. Although the adsorber 8 has been activated, the negative pressure is limited inside the vertical slot 701 and does not act on the top of the straight plate 7. As the fabric continues to be conveyed, its own weight and the tensile tension brought by the guide roller 10 work together to squeeze the top of the hollow block 91. Due to the low elasticity coefficient of the spring 93, the fabric can quickly overcome the elasticity and push the hollow block 91 along the vertical slot 701. As the horizontal plate 92 moves downward, it slides down synchronously along the two guide rods 73, compressing the spring 93. At this time, the contact between the hollow block 91 and the protrusion 72, and between the end hollow block 91 and the side plate 71, is released, forming an interlaced gap between the hollow block 91 and the straight plate 7. The vertical slot 701 connects to the top of the straight plate 7 through this gap. The negative pressure generated by the absorber 8 acts on the bottom surface of the fabric through the vertical slot 701, the interior of the hollow block 91, and the gap, achieving adsorption. Different sizes of fabric will compress different numbers of hollow blocks 91, opening the corresponding number of adsorption ports to achieve adsorption on demand, concentrate the suction force, and avoid energy waste. The fabric is then conveyed into the cutting area, where the support roller 2... The rotation drives the externally equidistant cutting devices 6 to move synchronously. The blades 65 in the cutting devices 6, driven by the tripod 64 and the ring 62, complete the cutting when they rotate above the fabric with the support roller 2. During the cutting process, the blades 65 do not contact the hollow block 91 to avoid damage to the parts due to collision. The telescopic rod 63 can pull the tripod 64 by telescopically extending and retracting, so that the ring 62 rotates around the center of the support roller 2 as the fulcrum, which facilitates the quick replacement of the blades 65. The cut abdominal belt blank continues to be conveyed to the receiving roller 3. The receiving roller 3, driven by the servo motor, winds up the blank at a speed that matches the conveying speed. During winding, a constant tension is maintained to prevent the blank from wrinkling.

The other end of the belt strip 11 is provided with a buckle 14, and two magnetic pieces 15 are fixedly connected to both sides of the buckle 14. The metal pieces 13 and the magnetic pieces 15 are the same size.
