Description

Technical Field

[0001] This utility model relates to the field of webbing cutting technology, and in particular to a vertical webbing cutting machine. Background Technology

[0002] Ribbon is a narrow-width or tubular fabric made from various yarns. There are many varieties of ribbon fabrics, which are widely used in various industries such as clothing, footwear, bags, industry, agriculture, military supplies, and transportation. With the development of textile technology, the raw materials used for ribbon have gradually expanded to include nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major categories of technology: weaving, braiding, and knitting. The fabric structure includes plain weave, twill weave, satin weave, jacquard, double layer, multi layer, tubular, and combined weave.

[0003] During the manufacturing process of webbing, a longer webbing is first produced. Then, according to the size requirements of the product, the long webbing is cut into short webbing segments of the required length. Existing webbing cutting equipment generally uses a vertical webbing cutter to quickly complete the equal-length cutting of long webbing.

[0004] Existing vertical tape cutting machines use conveyor rollers to clamp and transport the tape to the cutter for cutting. To ensure that the tape does not deviate during transport, two limiting plates are symmetrically installed near the inlet of the conveyor rollers. These limiting plates can limit the two sides of the tape to prevent the tape from deviating from its transport trajectory. However, when limiting the tape, the limiting plates will rub against the two sides of the tape, causing the tape sides to fray or become damaged. In particular, after prolonged friction between the limiting plates and the tape sides, dents, deformations, and rust may occur, causing more serious damage to the tape sides and severely reducing the quality of the cut tape.

[0005] To solve the above problems, a vertical tape cutting machine is urgently needed. Utility Model Content

[0006] The purpose of this utility model is to provide a vertical tape cutting machine to solve the problem mentioned in the background art that when the existing vertical tape cutting machine cuts the tape, the limiting plate that limits the tape will rub against the two sides of the tape, causing the sides of the tape to fray or be damaged, thus reducing the quality of the cut tape.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vertical tape cutting machine, including a base, wherein a limiting component, a conveying component and a cutting component are connected sequentially from right to left on the top of the base;

[0008] The limiting component includes two limiting plates symmetrically connected to the top of the base. Two inclined surfaces are symmetrically opened on the side of the two limiting plates that are close to each other. The two inclined surfaces are distributed in an inverted V-shape and are used to limit the front and rear sides of the conveyor belt.

[0009] The conveying assembly consists of two conveying rollers distributed vertically, which rotate in a certain direction to convey the webbing to the cutting assembly.

[0010] The cutting component is used to cut the webbing.

[0011] Preferably, the limiting component further includes two sets of rotating rollers symmetrically rotatably connected to the two inclined planes. Each set of multiple rotating rollers is equidistantly distributed along the length of the inclined plane. The advantage of this arrangement is that by having the two sets of rotating rollers contact the front and rear sides of the webbing, the friction force on the front and rear sides of the webbing can be significantly reduced, effectively preventing the front and rear sides of the webbing from fraying or being damaged during friction, thus improving the quality of the webbing after cutting.

[0012] Preferably, the two limiting plates are provided with a swing assembly, which is used to drive the two sets of rotating rollers to swing at the same angle in the direction of approaching or moving away from each other. The advantage of this setting is that by driving the two sets of rotating rollers to swing at the same angle in the direction of approaching or moving away from each other, the distance between the two sets of rotating rollers can be flexibly adjusted. In this way, the tilt angle of the two sets of rotating rollers can be adjusted. Thus, the tilt angle of the two sets of rotating rollers can be increased or decreased according to the thickness of the webbing. This can improve the limiting force on the webbing while ensuring that the webbing does not fold over, thus ensuring the effect and reliability of the webbing cutting process.

[0013] Preferably, the swing assembly includes two swing plates symmetrically rotatably connected to two inclined planes via a rotating seat, a first rotating rod, and a first torsion spring. Two sets of rotating rollers are symmetrically rotatably connected to the adjacent sides of the two swing plates. The swing assembly also includes two pairs of first electric push rods symmetrically fixedly connected to the top of two limiting plates. Two pairs of top rods are symmetrically fixedly connected to the output ends of the two pairs of first electric push rods. The adjacent ends of the two pairs of top rods are respectively pressed against the opposite sides of the two swing plates. The advantage of this arrangement is that when the two pairs of first electric push rods are activated to extend or retract, the two pairs of top rods, in conjunction with the first rotating rod and the first torsion spring, can stably and reliably drive the two swing plates and the two sets of rotating rollers to swing in opposite directions.

[0014] Preferably, the base is provided with a protective assembly, which includes two sets of round rods symmetrically fixedly connected to the adjacent sides of two swing plates via vertical plates. The number of round rods in each set is equal to the number of multiple rotating rollers in each set. Multiple guide plates are fixedly connected in a ring at equal angles on the outer circumference of the round rods. Two sets of moving tubes are symmetrically sleeved on the outer circumference of the two sets of round rods. Multiple guide grooves are formed in a ring at equal angles on the inner sidewall of the moving tubes. The multiple guide grooves on the moving tubes are respectively movably sleeved on the multiple guide plates on the round rods. The two sets of rotating rollers are respectively rotatably connected to the outer circumference of the two sets of moving tubes. Two sets of elastic elements are symmetrically fixedly connected to the ends of the two sets of moving tubes that are far apart. Two sets of compression rings are symmetrically fixedly connected to the ends of the two sets of elastic elements that are far apart from the moving tubes. Two pressure sensors are symmetrically fixedly connected to the side of the vertical plate near the compression rings. The compression rings abut against the two adjacent pressure sensors. The protective assembly also includes two pushing mechanisms symmetrically connected to the base front and rear. Two limiting plates are symmetrically connected to the two pushing mechanisms. The two pushing mechanisms are used to push the two limiting plates. The positioning plates move towards each other. The protection assembly also includes a controller and a power supply connected to the base. The pressure sensor and the pushing mechanism are respectively connected to the input and output terminals of the controller. The power supply is used to power the controller. The advantage of this arrangement is that when the webbing deviates in the forward or backward direction during the conveying process, the roller on the force side can be subjected to an axial pushing force. This overcomes the elastic force of the elastic element and pushes the moving tube along the guide plate towards the pressure sensor. This increases the squeezing force of the squeezing ring on the pressure sensor. The pressure sensor transmits the pressure change value to the controller. The controller activates the pushing mechanism based on the pressure value to push the limiting plate in the opposite direction to the webbing deviation. This ensures that the front and rear positions of the roller do not change significantly when the roller moves along the guide plate. This reduces the friction on the side of the webbing when the roller moves under pressure, thus preventing the webbing conveying direction from deviating. This effectively limits the webbing and reduces damage to the side of the webbing, greatly improving the safety and reliability of the tape cutting machine.

[0015] Preferably, the pushing mechanism includes a fixed plate fixedly connected to the top of the base. The top of the fixed plate has two sliding plates symmetrically connected to it via two sliding grooves. The tops of the two sliding plates are fixedly connected to the bottom of the limiting plate. A connecting plate is fixedly connected to the bottom of the limiting plate. Two second electric push rods are symmetrically fixedly connected to the top of the fixed plate. The output ends of the two second electric push rods are fixedly connected to the side of the connecting plate. The second electric push rods are connected to the output end of the controller. The advantage of this arrangement is that activating the extension and retraction of the two pairs of second electric push rods can stably push the two limiting plates to move towards each other.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, by setting two inclined planes distributed in an inverted V-shape, the webbing can slide slightly along the inclined direction when it shifts forward or backward. This can reliably limit the webbing while reducing the friction on the front and rear sides of the webbing, and prevent the webbing from getting fuzzy or damaged when it is limited, thus effectively improving the reliability and safety of the tape cutting machine.

[0018] 2. In this utility model, the protective components ensure that when the webbing deviates in the forward or backward direction during transport, the roller on the force-bearing side is subjected to an axial pushing force. This overcomes the elastic force of the elastic element and pushes the moving tube along the guide plate towards the pressure sensor. This increases the squeezing force of the compression ring on the pressure sensor, which transmits the pressure change value to the controller. The controller then activates the pushing mechanism based on the pressure value to move the limiting plate in the opposite direction to the webbing deviation. This ensures that the front and rear positions of the roller do not change significantly when it moves along the guide plate. By reducing the friction on the side of the webbing under pressure, the roller can avoid deviation in the conveying direction of the webbing. This effectively limits the webbing and reduces damage to the side of the webbing, greatly improving the safety and reliability of the tape cutting machine. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please refer to Figures 1-6 The vertical tape cutting machine shown includes a base 1, and a limit assembly 2, a conveying assembly 3 and a cutting assembly 4 are connected sequentially from right to left on the top of the base 1;

[0029] The limiting component 2 includes two limiting plates 21 symmetrically connected to the top of the base 1. Two inclined surfaces 22 are symmetrically opened on the side of the two limiting plates 21 that are close to each other. The two inclined surfaces 22 are distributed in an inverted V-shape. The two inclined surfaces 22 are used to limit the front and rear sides of the conveyor belt.

[0030] The conveying assembly 3 consists of two conveying rollers 31 distributed vertically. The two conveying rollers 31 rotate in a certain direction to convey the webbing to the cutting assembly 4.

[0031] Cutting component 4 is used to cut the webbing;

[0032] The cutting assembly 4 includes a fixed frame 41 fixedly connected to the top of the base 1. The inner ring of the fixed frame 41 is aligned with the gap between the two conveying rollers 31. Two cylinders 42 are symmetrically fixedly connected to the top of the fixed frame 41. The output ends of the two cylinders 42 pass through the top wall of the fixed frame 41 and extend into the inner ring of the fixed frame 41. A cutting blade 43 is fixedly connected between the output ends of the two cylinders 42. A cutting groove aligned with the cutting blade 43 is opened on the inner bottom wall of the inner ring of the fixed frame 41.

[0033] refer to Figures 1-4The limiting component 2 also includes two sets of rotating rollers 23 that are symmetrically rotatably connected to the two inclined planes 22, with multiple rotating rollers 23 in each set being equidistantly distributed along the length of the inclined plane 22.

[0034] Specifically, by having two sets of rotating rollers 23 contact the front and rear sides of the webbing, the friction force on the front and rear sides of the webbing can be significantly reduced, effectively preventing the front and rear sides of the webbing from getting fuzzy or damaged during friction, thus improving the quality of the webbing after cutting.

[0035] refer to Figures 1-4 Two limit plates 21 are equipped with swing components 5, which are used to drive the two sets of rotating rollers 23 to swing at the same angle in the direction of approaching or moving away from each other.

[0036] Specifically, the swing component 5 drives the two sets of rotating rollers 23 to swing at the same angle in the direction of approaching or moving away from each other, which can flexibly adjust the distance between the two sets of rotating rollers 23. In this way, the tilt angle of the two sets of rotating rollers 23 can be adjusted. The tilt angle of the two sets of rotating rollers 23 can be increased or decreased according to the thickness of the webbing. This can improve the limiting force on the webbing while ensuring that the webbing does not fold over, thus ensuring the effect and reliability of the webbing cutting process.

[0037] refer to Figures 1-4 The swing assembly 5 includes two swing plates 51 symmetrically rotatably connected to two inclined planes 22 via a rotating seat, a first rotating rod, and a first torsion spring. Two sets of rotating rollers 23 are symmetrically rotatably connected to the sides of the two swing plates 51 that are close to each other. The swing assembly 5 also includes two pairs of first electric push rods 52 symmetrically fixedly connected to the top of two limiting plates 21. Two pairs of push rods 53 are symmetrically fixedly connected to the output ends of the two pairs of first electric push rods 52. The ends of the two pairs of push rods 53 that are close to each other are respectively pressed against the sides of the two swing plates 51 that are far apart.

[0038] Specifically, the two pairs of first electric push rods 52 are activated to extend and retract, so that the two pairs of push rods 53, together with the first rotating rod and the first torsion spring, can stably and reliably drive the two swing plates 51 and the two sets of rotating rollers 23 to swing in opposite directions.

[0039] refer to Figures 1-6The base 1 is equipped with a protective component 6, which includes two sets of round rods 61 symmetrically fixed to the sides of two swing plates 51 near each other via vertical plates. The number of round rods 61 in each set is equal to the number of multiple rotating rollers 23 in each set. Multiple guide plates 62 are fixedly connected to the outer circumference of the round rods 61 at equal angles in a ring. Two sets of moving tubes 63 are symmetrically sleeved on the outer circumference of the two sets of round rods 61. Multiple guide grooves are opened at equal angles in a ring on the inner sidewall of the moving tubes 63. The multiple guide grooves on the moving tubes 63 are movably sleeved on the multiple guide plates 62 on the round rods 61. The two sets of rotating rollers 23 are rotatably connected to the outer circumference of the two sets of moving tubes 63. Two sets of rollers 23 are symmetrically fixed to the ends of the two sets of moving tubes 63 that are far apart. The elastic element 64 has two sets of compression rings 65 symmetrically fixedly connected to one end of the two sets of elastic elements 64 away from the moving tube 63. Two pressure sensors 66 are symmetrically fixedly connected to the side of the vertical plate near the compression rings 65. The compression rings 65 are pressed against the two pressure sensors 66. The protection component 6 also includes two pushing mechanisms 67 symmetrically connected to the base 1. Two limit plates 21 are symmetrically connected to the two pushing mechanisms 67. The two pushing mechanisms 67 are used to push the two limit plates 21 to move towards each other. The protection component 6 also includes a controller and a power supply connected to the base 1. The pressure sensors 66 and the pushing mechanisms 67 are respectively connected to the input and output terminals of the controller. The power supply is used to power the controller.

[0040] Specifically, when the webbing deviates in the forward or backward direction during the conveying process, the rotating roller 23 on the force-bearing side is subjected to an axial pushing force. This overcomes the elastic force of the elastic element 64 and pushes the moving tube 63 along the guide plate 62 towards the pressure sensor 66. This increases the squeezing force of the extrusion ring 65 on the pressure sensor 66. The pressure sensor 66 transmits the pressure change value to the controller. Based on the pressure value, the controller activates the pushing mechanism 67 to push the limiting plate 21 in the opposite direction to the webbing deviation. This ensures that the front and rear positions of the rotating roller 23 do not change significantly when it moves along the guide plate 62. When the rotating roller 23 moves under pressure to reduce the friction on the side of the webbing, it can prevent the webbing conveying direction from deviating. This effectively limits the webbing and reduces damage to the side of the webbing, greatly improving the safety and reliability of the tape cutting machine.

[0041] refer to Figures 1-4The pushing mechanism 67 includes a fixed plate 671 fixedly connected to the top of the base 1. The top of the fixed plate 671 is symmetrically connected to two sliding plates 672 via two sliding grooves. The top of the two sliding plates 672 is fixedly connected to the bottom of the limiting plate 21. The bottom of the limiting plate 21 is fixedly connected to a connecting plate 673. The top of the fixed plate 671 is symmetrically fixedly connected to two second electric push rods 674. The output ends of the two second electric push rods 674 are fixedly connected to the side of the connecting plate 673. The second electric push rods 674 are connected to the output end of the controller.

[0042] Specifically, activating the extension and retraction of the two pairs of second electric push rods 674 can stably push the two limit plates 21 to move towards each other.

[0043] Working principle: Based on the width of the webbing, the two pairs of first electric push rods 52 are activated to extend and retract. In this way, the two pairs of top rods 53, together with the first rotating rod and the first torsion spring, can stably and reliably drive the two swing plates 51 and the two sets of rotating rollers 23 to swing in opposite directions. This allows the tilt angle of the two sets of rotating rollers 23 to be increased or decreased according to the thickness of the webbing, thereby increasing the limiting force on the webbing while ensuring that the webbing does not fold over, thus ensuring the effect and reliability of the webbing cutting process.

[0044] Then, the free end of the webbing to be cut is passed through the gap between the two conveyor rollers 31 and through the inner ring of the fixed frame 41. Then, the conveyor assembly 3 is activated to drive the two conveyor rollers 31 to rotate in opposite directions to convey the webbing to the left. At the same time, the two cylinders 42 are activated to intermittently extend and retract to drive the cutting blade 43 to move up and down to complete the cutting of the webbing.

[0045] When the webbing deviates in the forward or backward direction during the conveying process, the rotating roller 23 on the force-bearing side is subjected to an axial pushing force. This overcomes the elastic force of the elastic element 64 and pushes the moving tube 63 along the guide plate 62 towards the pressure sensor 66. This increases the squeezing force of the extrusion ring 65 on the pressure sensor 66. The pressure sensor 66 transmits the pressure change value to the controller. The controller activates the pushing mechanism 67 based on the pressure value to push the limiting plate 21 in the opposite direction to the webbing deviation. This ensures that the front and rear positions of the rotating roller 23 do not change significantly when it moves along the guide plate 62. When the rotating roller 23 moves under pressure to reduce the friction on the side of the webbing, it can prevent the webbing conveying direction from deviating. This effectively limits the webbing and reduces the damage to the side of the webbing, greatly improving the safety and reliability of the tape cutting machine.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
