Description

Technical Field

[0001] The present invention relates to the technical field of cloth cutting, in particular to a sports protective abdominal belt and cutting equipment and a process for producing the abdominal belt. Background Art

[0002] The raw materials of abdominal bands need to be cut because the raw materials are mostly rolls or large pieces of cloth. The raw materials of abdominal bands mostly contain elastic fabrics, knitted fabrics, etc., which are easily stretched and deviated by external forces during cutting. If they are not fixed, the cutting edges are prone to skewness and the dimensional accuracy is out of control, resulting in the finished product not meeting the specifications.

[0003] However, in the prior art, when the fabric is loaded onto the conveyor belt, due to the lack of external force constraints, the fabric is very likely to wrinkle due to factors such as uneven distribution of its own gravity and slight vibrations during the operation of the conveyor belt. This not only affects the accuracy of subsequent processing steps, but may also cause damage to the fabric, reducing production quality and efficiency. To solve this problem, a centrifugal fan is often used in conjunction with a vacuum adsorption chamber. The vacuum suction is used to flatly adsorb the fabric on the conveyor belt to eliminate wrinkles. However, the vacuum adsorption chamber currently used has significant design limitations. The size of the adsorption area of ​​its vacuum suction is fixed and cannot be dynamically adjusted according to the actual coverage of the fabric on the conveyor belt. On the one hand, when the fabric area on the conveyor belt is smaller than the adsorption area of ​​the vacuum adsorption chamber, some adsorption areas will be uncovered by the fabric. However, since the adsorption area cannot be flexibly switched, these uncovered areas will continue to generate vacuum suction, resulting in the centrifugal fan having to continuously provide suction power to the ineffective areas. This part of the power output does not play any role in the adsorption of the fabric. The actual effect is purely meaningless consumption of energy. Long-term operation will significantly increase the energy consumption cost of production, which is contrary to the concept of energy saving and consumption reduction advocated in current industrial production. On the other hand, the continuous operation of the ineffective adsorption area will cause the dispersion of vacuum suction. The total suction of the vacuum adsorption system is relatively fixed. When part of the suction is used in the area without cloth, the effective suction actually acting on the area covered with cloth will be weakened, especially when conveying cloth at the edge of the cloth or with a smaller area. The impact of this suction dispersion is more obvious, which may cause the cloth to be unable to be firmly adsorbed, and then wrinkles will be generated again during the conveying process, and even offset, sliding and other phenomena will occur, which makes the original intention of vacuum adsorption fail, and can not guarantee the smooth conveying of the cloth, and causes waste. Summary of the Invention

[0006] Furthermore, side panels are provided on the top of both ends of the straight plate, a protrusion is provided on the top of the side of the straight plate away from the blade, a plurality of guide rods are fixedly connected to the inside of the straight plate, a vertical slot is opened inside the straight plate, the partition is located inside the vertical slot, and the output end of the adsorber is communicated with the vertical slot.

[0007] Furthermore, the partition 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 straight plate. The horizontal plate is slidably connected to the outside of the two guide rods. When the spring is not deformed, one side of the hollow block fits against the protrusion.

[0008] Furthermore, the upper portion of the hollow block is divided into a curved surface and an inclined surface, 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 notch, and the vertical length of the inclined surface is greater than the length of the fitting 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 with a top rotatably connected to the top 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 at the end is fitted with the side plate, the spring elastic coefficient is low, and when the top surface of the horizontal plate is fitted 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, a limit rod is fixedly connected to the body, and the limit rod is fixedly connected to two limit plates.

[0013] On the other hand, the present invention provides: a sports protective abdominal belt, which is made by a sports protective abdominal belt cutting device, including a belt strip, one end of the belt strip is provided with a pressure buckle, and metal sheets are provided on both sides of the pressure buckle, and the other end of the belt strip is provided with a lock buckle, and two magnetic sheets are fixedly connected on both sides of the lock buckle, and the metal sheet and the magnetic sheet are the same size.

[0014] The present invention also provides: a sports protective abdominal belt cutting process, using a sports protective abdominal belt cutting device, comprising the following steps: Spreading specifications: Spread the fabric around the outside of the take-up roller, control the number of layers, and use limiters and limit plates to fix the top of the fabric to prevent the fabric from shifting. Cutting operation: adjust the position of the cutter at the same time, and use the separator and absorber to further fix the bottom of the fabric.

[0015] Quality verification: After cutting with the cutter, the size deviation, edge smoothness and elastic consistency of the fabric are tested.

[0016] Beneficial effects of the present invention: 1. On-demand adsorption is achieved through multiple separators. The separators can close the adsorption ports. When the fabric covers the straight surface, the fabric's own weight, tensile tension and the action of the upper guide roller will squeeze the top of the separator, causing the separator to move down and open a 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 suction in areas without fabric, reduces energy waste, concentrates suction, enhances the adsorption effect on elastic fabrics, and makes adsorption more efficient.

[0017] 2. By achieving precise cutting, the synergistic effect of multiple positioning and dynamic adsorption ensures that the position of the abdominal band material is stable during the cutting process. The limiter and the limit plate form a dual positioning. The central axis of the limiter coincides with the central axis of the machine body. In combination with the limit plate, which can be adjusted by the limit rod, it can accurately assist in positioning the fabric. In addition, the side panels at both ends of the straight plate can further limit the position of the two sides when the fabric is large, effectively preventing the fabric from shifting due to conveying inertia or elastic deformation, avoiding cutting misalignment caused by edge deviation, and ensuring the cut size of the abdominal band blank is accurate.

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

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Example 1, with reference to Figures 1-8, which is a first embodiment of the present invention, provides a sports protective abdominal band cutting device, including a body 1, a support roller 2 fixedly connected to the top of the body 1, a storage roller 3 rotatably connected to one side of the body 1, a limiter 4 arranged above the body 1 and close to the storage roller 3, two limiter plates 5 symmetrically arranged about the central axis of the body 1, a plurality of cutters 6 equidistantly arranged and all fixedly connected to the outside of the support roller 2, a straight plate 7 fixedly connected to the body 1, an absorber 8 arranged inside the body 1, a plurality of separators 9 equidistantly arranged and all located inside 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 adsorber 8 is located below the straight plate 7 and the output end is interconnected with the inside of the straight plate 7. After the partition 9 is squeezed and moved downward, the output end of the adsorber 8 is interconnected with the top of the straight plate 7. Since multiple partitions 9 are provided, and the partition 9 closes the adsorption port, the adsorption port will be opened after the partition 9 moves downward. Different sizes of cloth squeeze different numbers of partitions 9, and thus different numbers of adsorption ports are opened, so that it can be adsorbed according to the needs of cloth of different sizes, and at the same time cooperate with the limiter 4 and the limit plate 5 for auxiliary positioning to achieve double positioning.

[0023] Specifically, the guide roller 10 squeezes the cloth, and the storage roller 3 stores the cut cloth. The adsorber 8 uses a variable frequency centrifugal fan, which is located below the straight plate 7 and is connected to the straight plate 7 through a pipe to provide negative pressure power for adsorption. The partition 9 can close a single adsorption unit. When the cloth covers the surface of the straight plate 7, the cloth's own weight and tensile tension squeeze the top of the partition 9 with the upper guide roller 10. The adsorption port of the unit is opened, 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 , side panels 71 are provided on the top of both ends of the straight plate 7, so that when the cloth is large, the side panels 71 are used to limit its two sides, and a protrusion 72 is provided on the top of the side of the straight plate 7 away from the blade 65. A plurality of guide rods 73 are fixedly connected to the inside of the straight plate 7, and a vertical slot 701 is opened inside the straight plate 7. The partition 9 is located inside the vertical slot 701, thereby closing the vertical slot 701. The output end of the adsorber 8 is communicated with the vertical slot 701, so that the adsorber 8 is used for adsorption.

[0025] Specifically, the side panels 71 and the limiting plates 5 form a double lateral limit. The limiting plates 5 can adjust the spacing to adapt to different model widths. The side panels 71 serve as fixed boundaries to prevent the fabric from exceeding the range of the limiting plates due to conveying inertia or elastic deformation, thereby avoiding cutting dislocation caused by edge deviation. The partition 9 needs to move down along the vertical slot 701 to open under the pressure of the fabric. The guide rod 73 can limit the lateral shaking of the partition 9 to ensure that it only makes stable movement in the vertical direction. The partition 9 is embedded in the groove to form a seal, and the output end of the adsorber 8 is directly connected to the vertical slot 701, forming an air flow channel for the adsorption area opened by the partition 9, which can adsorb the fabric. The scattered adsorption holes are integrated into a concentrated air flow channel, reducing the diffusion loss of negative pressure inside the straight plate 7, so that the suction force of the adsorber 8 acts more directly on the fabric contact area, thereby enhancing the grip on the elastic fabric.

[0026] Reference Figure 1-Figure 7 The partition 9 includes a hollow block 91 which is slidably connected to the vertical slot 701, a horizontal plate 92 which is fixedly connected to one side of the hollow block 91, and a spring 93 which is connected between the horizontal plate 92 and the straight plate 7. The horizontal plate 92 is slidably connected to the outside of the two guide rods 73, and the horizontal plate 92 is guided and limited by the two guide rods 73. 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 no longer contacts the protrusion 72, the spring 93 is compressed, and the hollow block 91 and the straight plate 7 are interlaced, and a gap appears, so that the output end of the adsorber 8 is interconnected with the top of the straight plate 7, and the cloth is located above the straight plate 7 and can squeeze the hollow block 91, so that the adsorber 8 can directly adsorb the cloth.

[0027] Specifically, the hollow inside of the hollow block 91 reduces its weight. When the fabric is transported to the top of the straight plate 7 and contacts the top of the hollow block 91, the fabric's own weight or transport tension forms a downward pressure on the hollow block 91. This pressure overcomes the elastic force of the spring 93, pushing the hollow block 91 down along the vertical slot 701. At the same time, the cross plate 92 slides down synchronously along the two guide rods 73. The spring 93 is compressed. As the hollow block 91 moves downward, its fit with the protrusion 72 is released, and an interlaced gap is formed on the top side and 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 the gap. The negative pressure generated by the adsorber 8 directly acts on the bottom surface of the fabric through the vertical slot 701, the inside of the hollow block 91 and the gap, thereby achieving precise adsorption of the fabric. The elastic force of the spring 93 can be preset according to the weight and elasticity of common fabrics, usually 5 to 10N. For light and thin fabrics, a slight pressure can trigger the opening.

[0028] Reference Figure 2-Figure 7The top 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 components due to collision. When the spring 93 is not deformed, the inclined surface 902 of the hollow block 91 is located outside the vertical slot 701, and the vertical length of the inclined surface 902 is greater than the length of the fitting 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, the top surface of the hollow block 91 will be squeezed to coincide with the top surface of the straight plate 7. Then, the downward length of the hollow block 91 is equal to the vertical length of the inclined surface 902. Therefore, the downward length is greater than the length of the contact surface between the protrusion 72 and the hollow block 91, so that the two are no longer in contact, forming an interlaced state for adsorption.

[0030] Reference Figure 2-Figure 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 is rotatably connected to the top 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 is concentric with the support roller 2, 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, so that the fixedly connected ring 62 rotates with the center of the supporting roller 2 as the fulcrum, thereby moving the blade 65 upward for quick replacement.

[0032] Reference Figure 2-Figure 6 Only the hollow block 91 at the end is in contact with the side panel 71 to strengthen the constraint on the edge of the fabric. The elastic coefficient of the spring 93 is low, ensuring that the fabric can quickly squeeze the hollow block 91. When the top surface of the horizontal plate 92 is in contact with the side panel 71, the top surface of the hollow block 91 is not higher than the top surface of the side panel 71, preventing the fabric from crossing the side panel 71 and deflecting.

[0033] Specifically, the spring 93 is not compressed by external force, and its elastic force pushes the horizontal plate 92 to slide upward along the guide rod 73, driving 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, and cooperates with the protrusion 72 to form a seal. The top opening of the vertical slot 701 is completely closed, and the negative pressure generated by the adsorber 8 is limited to the inside of 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 bulges that hinder the conveying of fabric.

[0034] Reference Figures 1-8The bottom end of the limiter 4 is rotatably connected to rollers 41 on both sides, and the double rollers 41 are used to push the top of the fabric. One end of the limiter 4 is rotatably connected to the body 1, so that the rollers 41 change with the thickness of the fabric. A limiting rod 101 is fixedly connected to the body 1, and the limiting rod 101 is fixedly connected to the two limiting plates 5. The position of the two limiting plates 5 can be changed by adjusting the limiting rod 101.

[0035] The working principle of the present invention is as follows: the raw material coil of the abdominal band is introduced into the equipment through the guide roller 10, and the guide roller 10 forms a preliminary extrusion on the cloth to ensure that the cloth is flat before entering the subsequent process. When the cloth is conveyed to the top of the straight plate 7, it first contacts the convex block 72 on the top of the straight plate 7 away from the blade 65. The convex block 72 blocks the sliding of the front end of the cloth, providing a clear feed reference line for the cloth, ensuring that the starting position of each section of cloth is consistent. At the same time, the side plates 71 at both ends of the straight plate 7 form a double lateral limit with the limit plate 5. The side plates 71 serve as a fixed boundary to prevent the cloth from exceeding the limit range due to conveying inertia or elastic deformation, effectively avoiding edge deviation. , the separator 9 located in the vertical notch 701 inside the straight plate 7 is in the 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 hollow block 91 at the end is still in contact with the side plate 71, closing the top of the vertical notch 701. The single adsorption unit is in a sealed state. Although the adsorber 8 has been started, the negative pressure is limited to the inside of the vertical notch 701 and does not act on the top of the straight plate 7. As the cloth 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 elastic coefficient of the spring 93, the cloth can quickly overcome the elastic force and push the hollow block 91 along the vertical notch 701. As the cloth moves downward, the horizontal plate 92 slides down synchronously along the two guide rods 73, and the spring 93 is compressed. At this time, the fitting state between the hollow block 91 and the protrusion 72, and the end hollow block 91 and the side plate 71 is released, and a staggered gap is formed between the hollow block 91 and the straight plate 7. The vertical notch 701 is connected to the top of the straight plate 7 through the gap. The negative pressure generated by the adsorber 8 acts on the bottom surface of the cloth through the vertical notch 701, the inside of the hollow block 91 and the gap to achieve adsorption. Cloths of different sizes will squeeze different numbers of hollow blocks 91, open the corresponding number of adsorption ports, achieve on-demand adsorption, concentrate suction, avoid energy waste, and enter the cutting area with the conveyor. The support roller 2 The rotation drives the external equidistantly arranged cutters 6 to move synchronously. The blade 65 in the cutter 6, driven by the tripod 64 and the ring 62, completes the cutting when the support roller 2 rotates to the top of the cloth. During the cutting process, the blade 65 does not contact the hollow block 91 to avoid damage to the components due to collision. The telescopic rod 63 can pull the tripod 64 through telescoping to make the ring 62 rotate with the center of the support roller 2 as the fulcrum, which facilitates the rapid replacement of the blade 65. The cut belly band blank is continuously conveyed to the storage roller 3. The storage roller 3 is driven by the servo motor to reel the blank at a speed matching the conveying speed. Constant tension is maintained during reeling to prevent the blank from wrinkling.

[0037] Example 3, reference Figures 1-8 , which is a third embodiment of the present invention, provides a sports protective abdominal belt cutting process, using a sports protective abdominal belt cutting device, including the following steps: Spreading specifications: Spread the fabric around the outside of the take-up roller 3, control the number of layers, and use the limiter 4 and the limit plate 5 to fix the top of the fabric to prevent the fabric from shifting. Cutting operation: adjust the position of the cutter 6 at the same time, and cooperate with the separator 9 and the absorber 8 to further fix the bottom of the fabric.
