Description

Technical Field

[0001] This utility model relates to the field of knitted fabrics, and in particular to a knitted fabric tensioning device. Background Technology

[0002] Knitted fabric is a fabric formed by bending yarns into loops and interlocking them using knitting needles. The difference between knitted fabric and woven fabric lies in the different forms of the yarns in the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics and linings, home textiles and other products.

[0003] A search revealed that Chinese Patent Publication No. CN220079343U discloses a knitted fabric pulling device. The combination of an electric telescopic rod, a connecting frame, a first guide roller, a pulling roller, and a pressing conveyor roller enables the knitted fabric to be pulled after production, ensuring that its surface is evenly stressed, thus improving its performance in subsequent use. Before pulling the knitted fabric, it avoids the need for workers to pass the knitted fabric through each guide roller one by one, reducing the labor intensity of the workers.

[0004] However, although the above-mentioned device can pull the fabric when in use, when dealing with fabrics of different widths, different molds need to be changed in order to prevent the fabric from shifting. The process of changing molds wastes a lot of time and affects the working efficiency of the device. Therefore, a knitted fabric pulling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a knitted fabric pulling device, which aims to improve the problem that the existing knitted fabric pulling devices need to change different molds for different fabrics, thus affecting the working efficiency of the device.

[0007] A housing is fixedly connected to the upper outer wall of the base between the take-up roller and the pull roller. A limit motor is fixedly connected to the outer wall of the housing. The output end of the limit motor passes through the outer wall of the housing and is fixedly connected to a bidirectional lead screw. A slide is drivenly connected to the outer wall of the bidirectional lead screw.

[0008] A connecting plate is fixedly connected to the outer wall of the slide block. A sliding rod is fixedly connected to the end of the connecting plate away from the slide block. A sliding sleeve is fitted on the outer wall of the sliding rod, and a clamping plate is fixedly connected to the outer wall of the sliding sleeve.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the base is fixedly connected to a fixed seat, and there are three sets of fixed seats. The winding roller, receiving roller, and pulling roller are rotatably connected to the inner wall of the three sets of fixed seats. The fixed seat is equipped with a motor and a pneumatic locking device.

[0011] As a further description of the above technical solution:

[0012] The output end of the electric push rod is fixedly connected to the fixed seat connected to the traction roller, and the clamping plate is sleeved on the outer wall of the traction roller and is slidably connected to the outer wall of the traction roller.

[0013] As a further description of the above technical solution:

[0014] The slide rod is configured as a rounded rectangle, the inner wall of the sliding sleeve fits against the outer wall of the slide rod, and the sliding sleeve is slidably connected to the outer wall of the slide rod.

[0015] As a further description of the above technical solution:

[0016] Both ends of the bidirectional lead screw are provided with slides, and the distance between the two sets of slides is the same as the length of the pulling roller.

[0017] As a further description of the above technical solution:

[0018] Both ends of the slide are provided with connecting plates. The interior of the connecting plate away from the electric push rod is provided with a limiting and locking component for the winding roller. The locking component includes a lower plate, which is fixedly connected to the outer wall of the connecting plate. An upper plate is rotatably connected to the end of the connecting plate near the lower plate. A baffle is rotatably connected to the end of the upper plate away from the connecting plate. A sliding groove is provided on the outer wall of the baffle. A slider is slidably connected to the inner wall of the sliding groove. A stop block is fixedly connected to the outer wall of the upper plate.

[0019] As a further description of the above technical solution:

[0020] The upper plate connected to one set of slides is rotatably connected to the baffle, and the other set of upper plates is fixedly connected to the stop block. The length of the baffle is the same as the length between the two sets of upper plates.

[0021] As a further description of the above technical solution:

[0022] The locking assembly is internally provided with magnetic sheets. There are two sets of magnetic sheets with opposite magnetic properties. One set of magnetic sheets is fixedly connected to the upper outer wall of the slider, and the other set of magnetic sheets is fixedly connected to the outer wall of the upper plate near the stop.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when dealing with fabrics of different widths, the limiting motor drives the bidirectional lead screw to move the two sets of sliding blocks and clamps on the pulling roller along with the sliding rod, limiting the two ends of the fabric on the pulling roller. At the same time, the upper plate and the lower plate move to limit the fabric on the winding roller. The clamps can move with the pulling roller on the sliding rod, so that the clamps do not affect the tension control of the pulling roller on the fabric. Thus, the device can stably pull the fabric without changing the mold when dealing with different fabrics, making the device more efficient.

[0025] 2. In this utility model, when the upper plate is closed, rotating the baffle causes the magnetic sheet on the slider to attract the magnetic sheet on the upper plate. When the upper plate moves, the slider moves in the groove, and at the same time the baffle is blocked by the stop block, so that the position of the baffle can be kept stable. The baffle blocks the take-up roller to prevent the fabric from being accidentally touched, which would cause the fabric to shift when pulled. When it is necessary to change the fabric on the take-up roller, simply push the baffle to make both sets of upper plates rotate and open at the same time, which is convenient for changing the fabric on the take-up roller and makes the device more efficient.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-4 An embodiment of this utility model provides a knitted fabric pulling device, including a base 1, a take-up roller 2 provided on the upper outer wall of the base 1, an electric push rod 4 fixedly connected to the upper outer wall of the base 1, a pulling roller 3 provided at the output end of the electric push rod 4, a receiving roller 5 provided on the outer wall of the base 1 away from the take-up roller 2, and a limiting component 6 provided on the outside of the base 1 to limit the fabric on the pulling roller 3. The limiting component 6 includes a housing 61, a limiting motor 62, a bidirectional lead screw 63, a slide 64, a connecting plate 65, a slide rod 66, a slide sleeve 67, and a clamping plate 68.

[0035] The housing 61 is fixedly connected to the upper outer wall of the base 1 between the winding roller 2 and the pulling roller 3. A limit motor 62 is fixedly connected to the outer wall of the housing 61. The output end of the limit motor 62 passes through the outer wall of the housing 61 and is fixedly connected to a bidirectional lead screw 63. A slide block 64 is drivenly connected to the outer wall of the bidirectional lead screw 63.

[0036] The connecting plate 65 is fixedly connected to the outer wall of the slide block 64. The end of the connecting plate 65 away from the slide block 64 is fixedly connected to the slide rod 66. The outer wall of the slide rod 66 is fitted with a sliding sleeve 67. The outer wall of the sliding sleeve 67 is fixedly connected to the clamping plate 68.

[0037] Reference Figures 1-4The outer wall of base 1 is fixedly connected to a fixed seat, and there are three sets of fixed seats. The winding roller 2, receiving roller 5, and pulling roller 3 are rotatably connected to the inner walls of the three sets of fixed seats. The fixed seats are equipped with motors and pneumatic locking devices. The motors are fixedly connected to the inner walls of the fixed seats. The winding roller 2 and receiving roller 5 can be connected and unlocked to the output end of the motor through the pneumatic locking device. The pulling roller 3 is fixedly connected to the output end of the motor. Electric pusher The output end of rod 4 is fixedly connected to a fixed base connected to the pull roller 3. Clamping plate 68 is sleeved on the outer wall of the pull roller 3 and slidably connected to it. Sliding rod 66 is a rounded rectangle. The inner wall of sliding sleeve 67 fits against the outer wall of sliding rod 66, and sliding sleeve 67 slidably connects to it. Clamping plate 68 can move with the pull roller 3 on sliding rod 66, and can also limit the upward movement of the pull roller 3. When frequently changing the position of the pull roller 3, grease can be added to the inner wall of the sliding sleeve 67, and the clamping plate 68 can also move on the pull roller 3 with the sliding rod 66 to limit the fabric on the pull roller 3. The inner wall of the clamping plate 68 is provided with an adjustable elastic flexible pad to prevent the clamping plate 68 from excessively squeezing the fabric. The clamping plate 68 is coated with a polytetrafluoroethylene coating, which can form a low-friction film when the clamping plate 68 contacts the fabric, avoiding the fabric from wrinkling due to hard friction between the clamping plate 68 and the edge of the fabric. When dealing with highly elastic fabrics, flexible guide strips can also be added to the inner wall of the clamping plate 68 to further disperse the pressure. Both ends of the bidirectional lead screw 63 are provided with sliding seats 64. The distance between the two sets of sliding seats 64 is the same as the length of the pull roller 3. The limiting motor 62 rotates the bidirectional lead screw 63, which can drive the two sets of sliding seats 64 to move simultaneously, limiting both ends of the fabric at the same time, thereby making the fabric more stable during transmission.

[0038] Reference Figures 1-5Both ends of the slide block 64 are provided with connecting plates 65. Inside the connecting plate 65 away from the electric push rod 4, there is a limiting and locking component 7 for the winding roller 2. The locking component 7 includes a lower plate 71, which is fixedly connected to the outer wall of the connecting plate 65. The end of the connecting plate 65 near the lower plate 71 is rotatably connected to an upper plate 72. The end of the upper plate 72 away from the connecting plate 65 is rotatably connected to a baffle 73. The outer wall of the baffle 73 has a groove 74. The inner wall of the groove 74 is slidably connected to a slider 75. The outer wall of the upper plate 72 is fixedly connected to a stop block 76. The upper plate 72 connected to one set of slide blocks 64 is rotatably connected to the baffle 73. The other set of upper plates 72 is fixedly connected to the stop block 76. The length of the baffle 73 is the same as the length between the two sets of upper plates 72. The locking component 7 is provided with magnetic sheets. There are two sets of magnetic sheets with opposite magnetic properties. One set of magnetic sheets is fixedly connected to the upper outer wall of the slider 75. The other set of magnetic sheets is fixedly connected to the outer wall near the stop block 76. On the outer wall of the upper plate 72 of 6, when the clamping plate 68 moves, the upper plate 72 and the lower plate 71 move simultaneously, so that the fabric on the take-up roller 2 can be synchronously limited with the fabric on the pulling roller 3, making the fabric more stable when being pulled. When it is necessary to change the fabric on the take-up roller 2, the baffle 73 can be rotated to make the magnetic piece on the slider 75 attract the magnetic piece on the upper plate 72. At this time, the two sets of upper plates 72 can be directly pushed to rotate, so that the upper plates 72 can be opened quickly, making it convenient to change the fabric on the take-up roller 2. When 72 is closed, the baffle 73 can also be rotated and connected to the upper plate 72 via a magnetic sheet. At this time, the baffle 73 is blocked by the stop block 76, which limits the position of the baffle 73. The baffle 73 can protect the winding roller 2 and block external objects to prevent the fabric from being accidentally touched and causing the fabric to shift when pulled. Both the slider 75 and the upper plate 72 are equipped with openable fixing sleeves. The magnetic sheet is fixed to the slider 75 and the upper plate 72 respectively through the fixing sleeves. The magnetic sheet can be replaced to prevent the magnetic force from weakening.

[0039] Working principle: One end of the fabric is passed from the take-up roller 2, around the pull roller 3, and connected to the receiving roller 5. At this time, the motor inside the fixed base controls the rotation of the take-up roller 2, pull roller 3, and receiving roller 5, thus pulling the fabric. When dealing with fabrics of different widths, the limit motor 62 drives the bidirectional lead screw 63 to rotate, causing the two sets of slides 64 to move simultaneously. The clamping plate 68 moves with the slide rod 66 on the pull roller 3, limiting the two ends of the fabric on the pull roller 3. Simultaneously, the clamping plate 68 moves with the pull roller 3 on the slide rod 66, ensuring that the clamping plate 68 does not affect the pull roller 3's control over the fabric tension. Meanwhile, the upper plate 7... 2. The lower plate 71 moves, so that the fabric on the take-up roller 2 is synchronously limited with the fabric on the pull roller 3, so that the device can stably pull the fabric without changing the mold when facing different fabrics. When the upper plate 72 is closed, the baffle 73 is rotated so that the magnetic piece on the slider 75 is attracted to the magnetic piece on the upper plate 72. At this time, the baffle 73 is blocked by the stop block 76, so that the baffle 73 protects the take-up roller 2 and prevents the fabric from being accidentally touched, which would cause the fabric to deviate during pulling. When it is necessary to change the fabric on the take-up roller 2, the baffle 73 is pushed directly to make the two sets of upper plates 72 rotate and open at the same time, so as to facilitate the replacement of the fabric on the take-up roller 2.

[0040] 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.
