A medical protective clothing fabric production device

Abstract

This utility model discloses a medical protective clothing fabric production device, relating to the field of fabric processing technology. It includes a base with symmetrically arranged support plates on its top. A drive motor is fixedly installed below the middle of the two support plates, and a drive disk is rotatably connected to the top of the two support plates. The bottom ends of the two drive disks are fixedly connected to the output shaft of the drive motor. A fabric clamping assembly is provided on the outer circumferential surface of the drive disk. This utility model uses a clamping structure composed of a pressure plate, the bottom of the clamping body, a rubber plate, an upper pressure rod, a lower pressure rod, and a counterweight in the fabric clamping assembly. The limiting rod controls the opening and closing of the pressure plate by limiting the trajectory of the arc-shaped plate. The counterweight enhances the clamping downward pressure. The upper and lower pressure rods cooperate to improve clamping stability. When thick fabric pushes the sliding plate, the slider slides along the crossbar and compresses the spring. The spring's restoring force causes the sliding plate to adhere to the fabric, achieving adaptive clamping of fabrics of different thicknesses and ensuring continuous and stable fabric conveying.

Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a medical protective clothing fabric production device. Background Technology

[0002] T / R four-way stretch fabric is a blended fabric widely used in the mid-range fashion market. It is usually made of polyester and rayon, with a certain proportion of elastic fibers such as spandex added to form a four-way stretch structure. It has excellent four-way stretch and can stretch in four directions: horizontal, vertical and diagonal, providing the wearer with good flexibility and freedom of movement.

[0003] Traditional spring-loaded fabric clamps typically consist of a clamping tooth base and a clamping base plate. Under gravity or spring force, the clamping tooth presses down on the fabric edge. The clamping tooth portion of the clamping tooth is mostly a planar structure. When in contact with the clamping base plate, the fabric is clamped by friction between the two. However, when dealing with T / R four-way stretch fabrics, due to the high elasticity of the fabric, the planar clamping teeth cannot evenly distribute the pressure, which can easily lead to localized situations where the clamping force is too tight or too loose. If it is too tight, the fabric edge will be stretched, resulting in subsequent hemming. If it is too loose, the fabric may detach from the clamp during high-temperature setting, causing hemming problems. This helps to stabilize the fabric width and weight, and reduce wrinkles in subsequent processing.

[0004] Therefore, it is necessary to invent a medical protective clothing fabric production device to solve the above problems. Summary of the Invention

[0024] 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.

[0025] This utility model provides, for example Figure 1 - Figure 6The device shown is a medical protective clothing fabric production apparatus, including a base 1. Support plates 2 are symmetrically arranged on the top of the base 1. A drive motor 3 is fixedly installed below the middle of the two support plates 2. Drive disks 4 are rotatably connected to the top of the two support plates 2. The bottom ends of the two drive disks 4 are fixedly connected to the output shaft of the drive motor 3. A fabric clamp assembly 5 is provided on the outer peripheral surface of the drive disks 4 to improve the fabric clamping stability. The fabric clamp assembly 5 includes a fixing block 501 rotatably connected to the drive disks 4. One side of the fixing block 501 is fixedly connected to... The blade clamp body has a bottom 502. A pressure plate 503 is hinged to one side of the fixing block 501 above the bottom 502 of the blade clamp body. A rubber plate 504 is fixedly installed at the bottom of the pressure plate 503. Multiple upper pressure rods 508 are fixedly installed at equal intervals at one bottom end of the rubber plate 504. Multiple lower pressure rods 509 that abut against the upper pressure rods 508 are fixedly installed at equal intervals at one top end of the bottom 502 of the blade clamp body. A sliding plate 513 for adjusting the tightness of the fabric clamping is provided on the top side of the bottom 502 of the blade clamp body near the lower pressure rods 509.

[0026] The base 1 provides bottom support for the entire device, ensuring the overall stability of the device. The support plate 2 is used to install the drive motor 3 and support the drive disk 4. The drive motor 3 provides rotational power to the drive disk 4, driving the drive disk 4 and the cloth clamp assembly 5 to rotate synchronously. The drive disk 4 rotates to move the cloth clamp assembly 5, realizing the switching of the cloth conveying and clamping positions. The core function of the cloth clamp assembly 5 is to improve the stability of cloth clamping and prevent the cloth from shifting or falling off during conveying. The fixing block 501 is used to connect the drive disk 4 to the bottom 502 of the blade clamp body and the pressure plate 503, realizing the rotational connection between the cloth clamp assembly 5 and the drive disk 4 and the fixation of each component. The bottom 502 of the blade clamp body provides a base structure for the cloth clamp assembly 5, which is used to install components such as the lower pressure rod 509 and the slide plate 513. The pressure plate 503 can rotate around the hinge point of the fixed block 501, and works with the bottom 502 of the blade clamp body to realize the clamping and releasing action of the cloth. The rubber plate 504 can increase the friction between the pressure plate 503 and the cloth, while avoiding the pressure plate 503 directly contacting the cloth and causing damage. The upper pressure rod 508 and the lower pressure rod 509 abut against each other, and the cooperation of the two enhances the clamping force on the cloth and prevents the cloth from slipping. The slide plate 513 can be adjusted according to the thickness of the cloth to adapt to the clamping tightness of different cloths and ensure the clamping effect.

[0027] A transverse groove 5020 is symmetrically provided on the top of the bottom 502 of the blade clamp body. A crossbar 510 is fixedly installed in the transverse groove 5020. A slider 512, which is fixedly connected to the bottom of the slide plate 513, is movably passed through the crossbar 510. A compression spring 511 is sleeved on the outer circumferential surface of the crossbar 510, with its two ends abutting against the bottom 502 of the blade clamp body and the slider 512, respectively. The transverse groove 5020 provides installation space for the crossbar 510, the slider 512 and the compression spring 511. The crossbar 510 guides the sliding of the slider 512, ensuring that the slider 512 moves in a fixed direction. The slider 512 is fixedly connected to the slide plate 513 and can drive the slide plate 513 to move synchronously, realizing the position adjustment of the slide plate 513. The compression spring 511 provides a restoring force to the slider 512 through its own elastic deformation, so that the slide plate 513 maintains the initial clamping position when no external force is applied, while buffering the pressure caused by changes in the thickness of the fabric.

[0028] A rectangular groove 5040 is provided on the top of the rubber plate 504. A counterweight 505 is fitted inside the rectangular groove 5040. The rectangular groove 5040 provides installation and positioning space for the counterweight 505, ensuring that the counterweight 505 is stably fixed on the rubber plate 504. The counterweight 505 increases the weight at the bottom of the pressure plate 503, enhances the downward pressure of the pressure plate 503 on the fabric, further improves the stability of the fabric clamping, and prevents the fabric from loosening.

[0029] A right-angle plate 506 is fixedly installed on the top of the pressure plate 503. An arc-shaped plate 507 is fixedly installed vertically at the right angle of the right-angle plate 506. The right-angle plate 506 is used to connect the pressure plate 503 and the arc-shaped plate 507, so as to fix the arc-shaped plate 507 on the top of the pressure plate 503. The arc-shaped plate 507 can cooperate with the subsequent limiting rod 9 to control the rotation angle of the pressure plate 503 through sliding contact, so as to ensure the accuracy of the fabric clamping action.

[0030] A right-angle bracket 8 is fixedly installed on the top of the drive motor 3 near the drive disk 4. A limiting rod 9 that is slidably connected to the bottom of the arc plate 507 is fixedly installed at one end of the right-angle bracket 8. The right-angle bracket 8 provides fixed support for the limiting rod 9, ensuring that the limiting rod 9 is in a position that matches the arc plate 507. The limiting rod 9 is slidably connected to the bottom of the arc plate 507, which can limit the movement trajectory of the arc plate 507 when the drive disk 4 rotates, thereby controlling the opening and closing of the pressure plate 503.

[0031] A stepper motor 6 is fixedly installed at the end of the drive motor 3. The output end of the stepper motor 6 is provided with a second limiting roller 7 for assisting in fabric clamping. The stepper motor 6 provides rotational power to the second limiting roller 7 and can adjust its own speed according to the fabric conveying speed. The second limiting roller 7 assists in fabric clamping by rotating, and plays a guiding and pressing role on the fabric, preventing the fabric from wrinkling or shifting during the conveying process, and improving the smoothness of fabric conveying.

[0032] A horizontal shaft 102 is movably inserted through one end of the top of the base 1. A first limiting roller 103 for assisting in fabric conveying is fixedly inserted through the horizontal shaft 102. A groove 101 is provided at the other end of the top of the base 1. A pulley 201, which is fixedly connected to the bottom of the support plate 2, is slidably connected in the groove 101. A double-ended lead screw 202 is threadedly connected to the side of the support plate 2. A servo motor 203, which is fixedly connected to the base 1, is fixedly connected to one end of the double-ended lead screw 202. The other end of the double-ended lead screw 202 is rotatably connected to the base 1. The horizontal shaft 102 provides rotational support for the first limiting roller 103, ensuring that the first limiting roller 103 can rotate stably around its own axis. 3. By rotating the auxiliary fabric conveyor, the fabric enters the device in the initial stage, which guides the fabric and prevents jamming at the fabric inlet. The chute 101 provides a sliding track for the pulley 201, which restricts the movement direction of the support plate 2. The pulley 201 reduces the friction between the support plate 2 and the base 1, allowing the support plate 2 to move smoothly along the chute 101. The double-ended screw 202 rotates to drive the two support plates 2 to move closer or further away synchronously, thereby adjusting the distance between the support plates 2. The servo motor 203 provides rotational power to the double-ended screw 202, ensuring the accuracy of the rotation of the double-ended screw 202, and thus achieving precise adjustment of the distance between the support plates 2 to adapt to fabrics of different widths.

[0033] The working principle of this utility model is as follows: By starting the servo motor 203 on the base 1, the servo motor 203 drives the double-ended lead screw 202 to rotate. Since the double-ended lead screw 202 is threadedly connected to the support plate 2, and the bottom end of the support plate 2 is slidably engaged with the slide groove 101 of the base 1 through the pulley 201, the rotation of the double-ended lead screw 202 will cause the two support plates 2 to move closer or further away from each other along the slide groove 101 until the spacing between the support plates 2 matches the width of the fabric, thus completing the adjustment of the width dimension of the device. Subsequently, the drive motor 3 and the stepper motor 6 are started, and the device enters the fabric feeding stage. One end of the fabric is fed into the base 1 from the first limiting roller 103 at the top. The first limiting roller 103 rotates stably with the support of the horizontal shaft 102, which guides the fabric and prevents it from getting stuck at the inlet. At the same time, the stepper motor 6 drives the second limiting roller 7 to rotate. The second limiting roller 7 adjusts its own speed according to the subsequent conveying speed driven by the drive motor 3, and performs secondary guidance and compression on the fabric to prevent wrinkles or deviations in the fabric during the introduction process, ensuring that the fabric enters the clamping area of ​​the fabric clamp assembly 5 smoothly. When the fabric enters the clamping area, the drive motor 3 drives the top drive disk 4 to rotate. The fabric clamp assembly 5 on the outer periphery of the drive disk 4 moves synchronously with the drive disk 4. During this process, the limiting rod 9 on the right-angle bracket 8 at the top of the drive motor 3 slides into contact with the bottom of the arc plate 507 at the top of the pressure plate 503. The limiting rod 9 controls the pressure plate 503 to rotate around the hinge point of the fixed block 501 by limiting the movement trajectory of the arc plate 507. When the arc plate 507 rotates with the drive disk 4 to contact the limiting rod 9, the limiting rod 9 limits the arc plate 507, causing the pressure plate 503 to open and close up and down. After the fabric enters between the pressure plate 503 and the bottom 502 of the blade body, the upper pressure rod 508 on the bottom rubber plate 504 gradually... The pressure bar 509 at the bottom 502 of the blade clamp body abuts against the upper pressure bar 508 and the lower pressure bar 509. At the same time, the counterweight 505 in the rectangular groove 5040 at the top of the rubber plate 504 increases the downward pressure of the pressure plate 503, thereby enhancing the clamping force of the upper pressure bar 508 and the lower pressure bar 509 on the fabric. If there is a difference in fabric thickness, the excessively thick fabric will push up the rubber plate 504. Meanwhile, the slide plate 513 on the bottom 502 of the blade clamp body slides along the crossbar 510 via the bottom slider 512. At the same time, the compression spring 511 is compressed. The elastic deformation of the compression spring 511 will provide a reverse restoring force for the slider 512, so that the slide plate 513 always fits the fabric, adapting to the clamping tightness of fabrics of different thicknesses, and avoiding the fabric being clamped too loosely or too tightly due to changes in thickness.

[0034] The drive disk 4 rotates continuously, causing the cloth clamping assembly 5, which has clamped the cloth, to move along the outer periphery of the drive disk 4. During the movement, the cloth clamping assembly 5 maintains a stable clamping of the cloth, thereby causing the cloth to move synchronously with the cloth clamping assembly 5, realizing continuous and stable conveying of the cloth until the cloth is conveyed to the designated position. Then, the pressure plate 503 is opened by the subsequent mechanism to complete a single cloth conveying process.

[0035] It should be noted that the servo motor 203, drive motor 23 and stepper motor 6 in this embodiment can all be connected to an external power source, and each is equipped with a control device that matches the respective device.

[0036] 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.
