Description

Technical Field

[0001] This utility model relates to the field of garment production equipment technology, and in particular to a fabric tension adjustment device in garment production. Background Technology

[0002] In industrialized garment production, fabric transport and handling are fundamental steps in core processes such as cutting, sewing, and finishing. The stability of fabric tension directly determines the precision of subsequent processing and the quality of the finished product. In current mainstream garment production lines, fabric typically undergoes multiple processes such as unwinding, guiding, and rewinding. If the fabric tension is not properly controlled during this process, it can easily lead to a series of production problems. When the tension is too high, it can easily cause the fabric to stretch and deform (especially affecting elastic fabrics such as spandex blends), resulting in cutting size deviations and fabric wrinkling during sewing. When the tension is too low, the fabric is prone to loosening and stacking, leading to transport deviations, which not only reduces production efficiency but may also cause equipment jamming and increase fabric waste. Chinese Patent Publication No. CN219099642U discloses a tension adjustment device based on fabric production, including a base. A fixing plate is fixedly installed on both the front and rear sides of the upper middle part of the base. A sliding groove is formed on the opposing surfaces of the two fixing plates. An adjustment mechanism is jointly provided on the opposing surfaces of the two fixing plates. A cleaning device is provided in the upper part of the inner cavity of the adjustment mechanism. A feeding roller is movably connected to the upper left side of the base, and a winding roller is movably connected to the upper right side of the base. This invention cleans dust and loose threads from the lower surface of the fabric body by the friction between the rotating sponge roller and the fabric body during the conveying process. A brush roller cleans dust and loose threads from the upper surface of the fabric body, ensuring the cleanliness of the fabric body surface and making the fabric body clean during winding, thus guaranteeing the winding quality. The aforementioned patent documents still have the following defects in practice: The cleaning device relies on a combination of a "sponge roller (cleaning the lower surface) + brush roller (cleaning the upper surface)," but only describes the process of "friction cleaning of dust and lint," without setting up a structure for collecting impurities. In actual use, the dust and lint cleaned by the sponge roller and brush roller will scatter to the base or re-adhere to the fabric surface, forming a vicious cycle of "cleaning - scattering - secondary pollution." This not only fails to guarantee the winding quality but may also affect the operation of the equipment due to the accumulation of impurities (such as the chute being stuck by lint, causing the adjustment mechanism to jam). Utility Model Content

[0003] The main purpose of this invention is to provide a fabric tension adjustment device for garment production, which can effectively solve the problems mentioned above.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fabric tension adjustment device for garment production includes a support frame, a take-up drum and a tension mechanism on the right side of the support frame, a guide cylinder in the middle of the support frame, an unwinding drum on the left side of the support frame, two impurity removal mechanisms on the left side of the support frame, and a transmission mechanism in front of the impurity removal mechanism located on the right side.

[0005] Preferably, the tension mechanism includes a strip plate, which is disposed on the right side of the bracket. Two telescopic sleeves are provided on the upper part of the strip plate, and a telescopic rod is provided in the middle of the telescopic sleeve. A support rod is provided on the upper part of the two telescopic rods, and a second spring is sleeved on the outside of the two telescopic rods. The second spring is connected to the strip plate and the support rod respectively.

[0006] Preferably, the impurity removal mechanism includes a depilatory cylinder, which is disposed on the left side of the support, and a gear is provided at the rear of the depilatory cylinder.

[0007] Preferably, the impurity removal mechanism includes a fixing strip, a fixing frame, and a support plate. The fixing strip, fixing frame, and support plate are arranged on the left side of the bracket. The upper part of the support plate is provided with two springs, and the upper part of the two springs is provided with a T-shaped plate. The vertical end of the T-shaped plate slides within the strip groove formed by the fixing strip and the fixing frame.

[0008] Preferably, the impurity removal mechanism includes a collection box, which is disposed on the upper part of the fixed frame. The part of the collection box that contacts the depilatory cylinder is an inclined scraper, which facilitates scraping off and collecting the lint and dust brought out by the depilatory cylinder. Two gears mesh with each other.

[0009] Preferably, the transmission mechanism includes a motor, which is located at the front of the bracket, and the output end of the motor is connected to the front of the depilatory cylinder located on the right.

[0010] Preferably, the transmission mechanism includes a first pulley, which is located at the front of the dehairing drum on the right side. The outer surface of the first pulley is provided with a transmission belt, and the end of the transmission belt away from the first pulley is provided with a second pulley, which is located at the front of the take-up drum.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This device features a designed lint removal mechanism with two interlocking lint removal cylinders that rotate synchronously in opposite directions via a transmission mechanism. As the fabric passes between the two cylinders, the nylon fleece-covered cylinders simultaneously and meticulously wipe the upper and lower surfaces of the fabric, efficiently adsorbing lint, dust, and other impurities. Compared to traditional single-roller cleaning or single-surface cleaning methods, the cleaning coverage is improved, making it particularly suitable for thin and sensitive fabrics (such as silk and knitted fabrics). This avoids scratching and damage to the fabric during the cleaning process. The collection box, which is paired with the lint removal mechanism, uses an inclined scraper structure at the contact point with the lint removal cylinders. This structure can scrape off impurities adhering to the surface of the lint removal cylinders in real time and collect them into the box, completely solving the vicious cycle of "cleaning - scattering - secondary adhesion" in traditional devices. In addition, the collection box is easily disassembled and cleaned through a quick-fixing structure using a T-shaped plate and a spring, preventing impurities from accumulating and clogging equipment components, ensuring long-term stable operation of the device, and ensuring that the surface of the fabric is clean after winding, eliminating the need for additional subsequent cleaning processes.

[0012] 2. This device, through its designed tension mechanism, employs an elastic combination structure of "telescopic sleeve + telescopic rod + spring two," which can dynamically adjust according to the actual tension of the fabric. When the fabric tension is too high, the support rod is compressed, causing the telescopic rod to contract, and spring two is compressed to generate a reverse buffering force, relieving tensile stress and preventing permanent deformation of elastic fabrics (such as spandex blends) due to excessive stretching. When the tension is too low, spring two rebounds, pushing the support rod back to its original position, tightening the fabric and preventing it from slack and stacking, which could lead to transmission deviation. This fundamentally reduces quality problems such as cutting size deviation and sewing wrinkles. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1, as Figure 1 - Figure 2 As shown, a fabric tension adjustment device in garment production includes a support 1, a take-up drum 2 on the right side of the support 1, a tension mechanism 7 on the right side of the support 1, a guide drum 6 in the middle of the support 1, a release drum 5 on the left side of the support 1, two impurity removal mechanisms 4 on the left side of the support 1, and a transmission mechanism 3 in front of the impurity removal mechanism 4 located on the right side. In this embodiment, a damper is provided between the unwinding drum 5 and the support 1. It can be flexibly adapted according to the thickness, material and transmission speed of the fabric 8 to ensure that the damping force can effectively prevent the unwinding drum 5 from rotating excessively, and will not cause the fabric 8 to be pulled and deformed due to excessive damping. After the fabric is released from the unwinding drum 5, it first passes through the impurity removal mechanism 4 to remove impurities, so as to avoid these excess impurities from adhering to the surface of the fabric 8 and causing the fabric 8 to deviate during transmission. It can also reduce the uneven tension caused by impurities protruding or accumulating when the fabric 8 enters the tension mechanism 7. After passing through the guide drum 6 and the tension mechanism 7 to adjust the tension, it is then neatly wound up by the take-up drum 2. To make the device work, refer to Figure 2 The transmission mechanism 3 includes a motor 31, which is located at the front of the bracket 1. The output end of the motor 31 is connected to the front of the depilatory drum 41 located on the right. The transmission mechanism 3 includes a pulley 32, which is located at the front of the depilatory drum 41 located on the right. A transmission belt 33 is provided on the outer surface of the pulley 32. A pulley 34 is provided at the end of the transmission belt 33 away from the pulley 32. The pulley 34 is located at the front of the take-up drum 2. During implementation, the motor 31 is started, which drives the pulley 32 and the de-hairing cylinder 41 located on the right to rotate. The pulley 32 drives the pulley 34 to rotate through the transmission belt 33. The pulley 34 drives the winding cylinder 2 to rotate, and winds up the fabric 8.

[0017] Example 2: To remove impurities from the fabric, refer to... Figure 4The impurity removal mechanism 4 includes a de-hairing cylinder 41, which is located on the left side of the support 1. A gear 48 is provided at the rear of the de-hairing cylinder 41. The impurity removal mechanism 4 includes a fixing strip 43, a fixing frame 47, and a support plate 46. The fixing strip 43, the fixing frame 47, and the support plate 46 are located on the left side of the support 1. Two springs 45 are provided on the upper part of the support plate 46. A T-shaped plate 44 is provided on the upper part of the two springs 45. The vertical end of the T-shaped plate 44 slides in the strip groove formed by the fixing strip 43 and the fixing frame 47. The impurity removal mechanism 4 includes a collection box 42, which is located on the upper part of the fixing frame 47. The part of the collection box 42 that contacts the de-hairing cylinder 41 is an inclined scraper, which facilitates scraping off and collecting the lint and dust brought out by the de-hairing cylinder 41. The two gears 48 mesh with each other. During implementation, the T-shaped plate 44 is pressed down to place the collection box 42 on the fixing frame 47. The T-shaped plate 44 is then released, and springs back under the action of spring 45, fixing the position of the collection box 42. The fabric 8 passes between the two depilatory cylinders 41. The motor 31 drives the right depilatory cylinder 41 to rotate, and the right depilatory cylinder 41 drives the left depilatory cylinder 41 to rotate via gear 48. The two depilatory cylinders 41 rotate synchronously to remove impurities from the surface of the fabric 8, adsorbing loose threads and dust. The collection box 42 scrapes off the impurities carried out by the depilatory cylinders 41 using an inclined scraper. The outer ring of the lint remover 41 is made of nylon fleece. Nylon fleece is fine, soft and has strong adsorption properties, which can effectively stick to the fine threads and dust on the surface of the fabric 8. At the same time, the soft texture will not scratch or damage the fabric 8, making it suitable for the impurity removal needs of various thin and sensitive fabrics. In addition, the nylon material is wear-resistant and aging-resistant, which can extend the service life of the lint remover. The surface of the fabric 8 after removing impurities is smoother, avoiding these excess impurities from adhering to the surface of the fabric 8 and causing the fabric 8 to deviate during transmission. It can also reduce the uneven tension caused by impurities protruding or accumulating when the fabric 8 enters the tension mechanism 7. To ensure the fabric is taut, refer to... Figure 3 The tension mechanism 7 includes a strip plate 71, which is located on the right side of the bracket 1. Two telescopic sleeves 72 are provided on the upper part of the strip plate 71. A telescopic rod 73 is provided in the middle of the telescopic sleeve 72. A support rod 75 is provided on the upper part of the two telescopic rods 73. A second spring 74 is sleeved on the outside of the two telescopic rods 73. The second spring 74 is connected to the strip plate 71 and the support rod 75 respectively. During implementation, when the tension of fabric 8 is too high, it will pull the support rod 75 downward. The support rod 75 will drive the telescopic rod 73 to slide downward within the telescopic sleeve 72, while compressing the second spring 74. The reaction force generated by the second spring 74 will relieve the tension of fabric 8. When the tension of fabric 8 is too low, the second spring 74 will return to its original state and push the support rod 75 upward, thereby increasing the tension of fabric 8 and achieving stable adjustment of the tension of fabric 8. The telescopic sleeve 72 and the telescopic rod 73 limit the movement direction of the support rod 75.

[0018] It should be noted that the specific installation method of the motor 31, the circuit connection method, and the control method used in this utility model are all conventional designs, and will not be described in detail in this utility model.
