Description

Technical Field

[0001] This utility model relates to the field of mechanical property testing technology for textile materials, specifically to a pneumatic clamping type fabric strength tester. Background Technology

[0002] As a vital component of traditional manufacturing, the textile industry has consistently strived to improve product quality and technological advancements. With the continuous emergence of new fiber materials, functional fabrics, and high-performance composite materials, higher demands are being placed on the tensile, tear, and bursting strength testing of fabrics. Pneumatic clamping fabric tensile testing machines, with their high precision and stability, can meet the diverse needs of the textile industry for testing fabric mechanical properties, providing strong support for textile research and development, production, and quality control.

[0003] Chinese patent CN214121807U discloses a pneumatic clamping type fabric strength tester, including a fabric strength tester base. A first frame and a second frame are fixedly connected to the top of the base. A common top plate is fixedly connected to the top of both the first and second frames. Connecting grooves are formed on the sides of the first and second frames that are close to each other. Connecting plates are slidably connected to both grooves. A common sliding plate is fixedly connected to the ends of the two connecting plates that are close to each other. A pressing plate is fixedly connected to the bottom of the sliding plate, and a pressing groove is formed at the bottom end of the pressing plate. This invention fixes and clamps the fabric on the fabric strength tester base by lowering the clamping plate and flattens the fabric by horizontally moving two soft brush plates. This solves the problem of wrinkles in the fabric during testing, which may lead to errors in the test data. It has high working efficiency and meets the needs of users.

[0004] In the use of pneumatic clamping type fabric strength testers in related technologies, the fabric to be tested cannot be automatically fed, which leads to the need for manual feeding.

Detailed Implementation The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0018] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3As shown, it illustrates a pneumatic clamping type fabric strengthening machine according to an embodiment of the present invention, including a strengthening machine body 1, a control panel 5 installed on the front of the strengthening machine body 1, a feeding component 2 fixed on the other side of the strengthening machine body 1, a clamping block 4 installed inside the strengthening machine body 1, and an adsorption component 3 fixed on the side of the clamping block 4. The feeding assembly 2 includes a support block 21, a feeding box 22 fixed to the side of the support block 21, a feeding trough 23 fixed to the inner wall of the feeding box 22, a support plate 24 fixed to the bottom of the feeding trough 23, a first cylinder 25 fixed to the side of the feeding box 22, a push plate 26 fixed to the other end of the first cylinder 25, a laser sensor 27 fixed to the inner wall of the feeding box 22, a transmission roller 28 fixed to the bottom of the feeding box 22, and a discharge port 29 opened on the side of the feeding box 22. The laser sensor 27 is an LRFS-0200-1 type sensor, which is used to detect the fabric pushed by the push plate 26, thereby controlling the rotation of the transmission roller 28 through the control panel 5 to transmit the fabric. The feeding trough 23 is used to limit the fabric to be tested, thereby preventing the fabric from scattering in the feeding box 22.

[0024] In some examples, the discharge port 29 is located on the side of the transfer roller 28, and the transfer direction of the transfer roller 28 is to transfer towards the discharge port 29, thereby causing the fabric to move to the outside of the upper feed box 22 and be clamped by the clamping block 4.

[0025] In some examples, the feeding box 22 has separation grooves 210 on both sides. A second cylinder 211 is fixed at the bottom of the separation groove 210. An extension block 212 is fixed at the top of the second cylinder 211. An electric push rod 213 is fixed on the side of the extension block 212. A separation plate 214 is fixed at the other end of the electric push rod 213. The second cylinder 211 is used to drive the separation plate 214 to move up and down in the separation groove 210, so that the fabric to be tested separated by the separation plate 214 is separated from the fabric to be tested. The top of the separation plate 214 is a slope, which is used to separate the bottom fabric of the fabric to be tested from the top fabric, so as to avoid the situation of multiple layers of fabric overlapping when feeding the fabric.

[0026] In some examples, the separation groove 210 is formed between the support plates 24. There are two sets of support plates 24, which support both sides of the fabric respectively. A gap is left between the two sets of support plates 24 to facilitate the separation of the fabric.

[0027] In some examples, a connecting post 215 is fixed to the top of the clamping block 4, and a rotating shaft 216 is rotatably connected to the top of the connecting post 215. A motor 217 is fixed to the outside of the rotating shaft 216, and a support post 218 is fixed to the top of the rotating shaft 216. The motor 217 is electrically connected to the control panel 5. When the fabric to be tested is pushed out of the feeding box 22, the control panel 5 synchronously controls the motor 217 to drive the rotating shaft 216 to rotate, so that the clamping block 4 can rotate 90°.

[0028] For example, such as Figure 3 As shown, multiple sets of fabrics to be tested are first stacked and placed in the loading box 22 through the feeding chute 23. After the fabrics to be tested in the clamping block 4 have been tested, the electric push rod 213 controlled by the control panel 5 pushes the separation plate 214 between the bottom fabric and another fabric, thereby separating the bottom fabric from the other fabrics. Then, the extension block 212 is pushed upward by the second cylinder 211, and then the first cylinder 25 controlled by the control panel 5 pushes the separation groove 210 against the fabric box transfer roller 28. When the fabric moves to the laser sensor 27, the laser sensor 27 is activated. After detection by laser sensor 27, the control panel 5 controls the rotation of the transmission roller 28, which pushes the fabric to the discharge port 29. Then, the control panel 5 controls the motor 217 to drive the rotating shaft 216 to rotate, which causes the clamping block 4 to rotate 90° to the upper material box 22 and clamp the fabric. The clamping block 4 then rotates back to its original position, suspending the fabric. The control panel 5 then controls the clamping block 4 to move downward and clamp the fabric with another set of clamping blocks 4. The fabric can then be tested.

[0029] like Figures 4-5 As shown, it illustrates a pneumatic clamping type fabric strength machine in another embodiment of the present invention. The adsorption component 3 includes a negative pressure box 31, a negative pressure pump 32 fixed on the side of the negative pressure box 31, a blade 33 fixed on the output end of the negative pressure pump 32, and a conveying pipe 34 sealed to the bottom of the negative pressure box 31. The conveying pipe 34 is sealed to the inside of the clamping block 4. In some examples, the clamping block 4 has an adsorption port 35 on its inner side, and the conveying pipe 34 is sealed to the adsorption port 35. A pressure sensor 36 is fixed on the inner side of the clamping block 4. The pressure sensor 36 is a PTP-900-11 sensor, which is used to detect and sense when the clamping block 4 clamps the fabric, thereby controlling the negative pressure box 31 to perform negative pressure adsorption treatment.

[0030] In some examples, a telescopic tube 37 is sealed to one side of the delivery tube 34, and the other end of the telescopic tube 37 is fixed to the other side of the clamping block 4. The telescopic tube 37 is used to extend outward when the clamping block 4 is not in the clamping state, thereby facilitating the opening and closing state of the clamping block 4.

[0031] For example, such as Figure 3 As shown, when the fabric is clamped by the clamping block 4, the clamping pressure of the clamping block 4 is detected by the pressure sensor 36, and the negative pressure pump 32 is controlled by the control panel 5 to drive the blade 33 to rotate, thereby creating a negative pressure adsorption effect inside the negative pressure box 31, and the fabric is adsorbed by the adsorption port 35 at the other end of the delivery pipe 34, so as to prevent the fabric from shifting due to uneven clamping force. When the clamping block 4 clamps the fabric, the telescopic tube 37 can adapt to the opening and closing state of the clamping block 4 by contracting.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
