Description

Technical Field

[0001] This utility model relates to the technical field of fabric processing equipment, specifically to a tensioning fixture for the production of membrane split fiber cloth. Background Technology

[0002] Split fiber, also known as membrane split fiber, is a chemical fiber made from fiber-forming polymer films through uniaxial stretching and fiber breaking. It is an engineering term in the field of materials engineering. Its fiber formation principle is based on the characteristic that the axial strength of the film increases and the vertical strength decreases during uniaxial stretching, which causes the film to be longitudinally torn into a fibrous structure, eventually forming a network of fibrils.

[0003] Fabrics made from split-film fibers are widely used in various fields, including marine and aviation, due to their high strength, non-absorbency, corrosion resistance, abrasion resistance, and low specific gravity. However, when fabrics made from split-film fibers are used in certain specific fields, they require additional processing, such as spraying and lamination.

[0004] Chinese patent application CN 202010133926.3 discloses: "A method for manufacturing a membrane split fiber nonwoven fabric, including raw material preparation, adhesive spraying, film pressing, layering, fiber opening, and reinforcement. When spraying the adhesive, a dot matrix spraying method is used, with 30-72 spraying dots per square decimeter, and the area of ​​each spraying dot is between 0.005 cm2 and 0.04 cm2. Compared with the prior art, this method manufactures nonwoven fabric in a one-time molding process, and the fiber length inside the nonwoven fabric is controllable, which can enhance the overall mechanical properties of the membrane split fiber nonwoven fabric, resulting in higher tensile breaking strength, bursting strength, tear strength, etc., while also having good water and air permeability, making it suitable for use in civil engineering and other fields."

[0005] As described in the aforementioned patent, the fabrication of the membrane-split fiber requires multiple steps. In order to ensure uniform processing in steps such as spraying and pressing, the fabric must not only be stretched along its length but also fixed laterally to ensure that it is laid flat. However, since this type of fabric is composed of fibers, simply using clips to directly clamp the edges of the fabric will damage the edges. Summary of the Invention

[0006] In order to overcome the shortcomings of existing technologies that rely on clamps to fix the edges of the fabric during the processing of membrane split fiber fabric, which can lead to damage to the fabric edges, this utility model provides a tensioning fixture for the production of membrane split fiber fabric.

[0007] The technical solution of this utility model to solve its technical problem is: a tensioning fixture for the production of membrane split fiber cloth, including two clamping mechanisms arranged symmetrically on the left and right.

[0008] The clamping mechanism includes a support frame, an adsorption component, and a lifting component. Both the adsorption component and the lifting component are mounted on the support frame, and the adsorption component is located above the lifting component.

[0009] The adsorption assembly includes a suction plate with an air suction chamber inside. The bottom of the suction plate also has several air suction holes that connect to the air suction chamber. The suction plate is also connected to a connecting pipe seat that connects to the air suction chamber. The connecting pipe seat can be connected to an external air pipe. By drawing air through the external air pipe, a negative pressure can be formed in the air suction chamber to adsorb the edge of the fabric to the underside of the suction plate.

[0010] The lifting assembly includes a top claw and a lifting cylinder fixedly connected to the support frame. The piston rod of the lifting cylinder is connected to the top claw in a transmission manner. The extension and retraction of the piston rod of the lifting cylinder can drive the top claw to rise or fall, thereby driving the edge of the fabric placed above the top claw to move closer to or further away from the suction plate.

[0011] Furthermore, the suction plate is composed of an upper plate, a middle plate and a lower plate stacked in sequence. A through groove is provided on the middle plate, so that the groove wall, the lower side of the upper plate and the upper side of the lower plate together form an air suction chamber. The air suction hole is provided on the lower plate, and the connecting pipe seat is also protruding on the lower side of the lower plate.

[0012] Furthermore, a rotating shaft is connected to one side of the suction plate, and several adapter seats are fixed on the support frame. The rotating shaft is rotatably connected to the adapter seats. The adsorption assembly also includes a pressing cylinder, which is connected to the suction plate in a transmission manner, thereby enabling the suction plate to rotate up and down.

[0013] Furthermore, the pressing cylinder is located above the suction plate, and the piston rod of the pressing cylinder is set downward. An abutment plate is also connected to the suction plate, and the abutment plate is located above the suction plate. An abutment block is also connected to the free end of the piston rod of the pressing cylinder. The abutment block abuts against the abutment plate to realize the transmission connection between the pressing cylinder and the suction plate.

[0014] Furthermore, the suction plate is provided with several torsion spring holes, the support frame is provided with several torsion spring posts, and several reset torsion springs are also provided above the suction plate. One end of the reset torsion spring is connected to the torsion spring hole, and the other end is connected to the torsion spring post, so that the reset torsion spring acts on the suction plate so that it always has an upward flipping motion tendency.

[0015] Furthermore, the lifting assembly includes a top plate, and there are several lifting claws arranged along the length of the top plate. The piston rod of the lifting cylinder is connected to the top plate, and the lifting cylinder drives the top plate to move up and down, thereby driving the lifting claws to move up and down.

[0016] Furthermore, the lower end of the top claw is fixedly connected to the top plate, and the upper end of the top claw is also fixed with an anti-slip pad. The anti-slip pad has anti-slip texture, and the top claw contacts the edge of the fabric through the anti-slip pad.

[0017] Furthermore, the top plate is also connected to several guide blocks, and the support frame is connected to several guide rails. The guide blocks are slidably connected to the guide rails, and when the top plate moves up and down, the guide blocks can slide along the guide rails.

[0018] Furthermore, the clamping mechanism also includes a transverse track, and a transverse slider is connected to the support frame. The transverse slider is slidably connected to the transverse track so that the entire support frame can move laterally along the length of the transverse track.

[0019] This utility model addresses the process of clamping and releasing fabric edges:

[0020] First, the left and right clamping mechanisms can move according to the required processing section of the fabric. After the components on the support frame move to the required position relative to the transverse slide rail, the piston rod of the lifting cylinder extends and drives the top plate to rise. The top claw connected to the top plate pushes the edge of the fabric to rise. When the top claw rises to the highest position, the piston rod of the pressing cylinder extends and pushes the abutment plate down through the abutment block. The suction plate connected to the abutment plate will flip down until the lower side of the suction plate contacts the upper side of the fabric edge. At this time, the edge of the fabric is located between the suction plate and the top claw. Then, the air in the suction chamber of the suction plate can be drawn out through the external air pipe, so that the suction chamber forms a negative pressure, thereby adsorbing the edge of the fabric to the lower side of the suction plate. At this time, the edge of the fabric is fixed between the suction plate and the top claw. When both edges of the fabric are fixed, the section of fabric is in a taut state.

[0021] When the edge clamping mechanism needs to loosen the fabric edge, the piston rod of the lifting cylinder retracts, causing the top claw to descend, and the piston rod of the pressing cylinder also retracts, causing the suction plate to flip upward, so that the edge of the fabric can detach from the suction plate and fall down.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The fabric edges are fixed by the combined action of suction plates and top claws. The suction plates can effectively reduce the compression of the fabric, thus effectively preventing the edges from deforming and being damaged during the tensioning process.

[0024] 2. The suction plate has a simple and effective structure. It relies on three layers of plates stacked in sequence to form an air suction chamber. It can not only adsorb the fabric, but also assemble and maintain the suction plate very conveniently.

[0025] 3. The top claws are multiple and arranged in a way that reduces the impact of the top claws on the edges of the fabric. The top claws are also equipped with anti-slip pads. The anti-slip pads contact the fabric, which not only provides anti-slip function but also further reduces damage to the fabric.

[0026] 4. Equipped with a transverse slide rail, the entire support frame can be moved laterally to adjust its position, making it suitable for tensioning fabrics of various lengths. Attached Figure Description

The suction plate 4 is also connected to an abutment plate 17, which is located above the suction plate 4. An abutment block 18 is also connected to the free end of the piston rod of the pressing cylinder 16. The abutment block 18 abuts against the abutment plate 17 to realize the transmission connection between the pressing cylinder 16 and the suction plate 4.

The anti-slip pad 23 has anti-slip texture 24, and the top claw 8 contacts the edge of the fabric through the anti-slip pad 23.

[0044] Combination Figure 2 , Figure 3 and Figure 6As shown, in this embodiment, a number of guide blocks 25 are connected to the top plate 22, and a number of guide rails 26 are connected to the support frame 1. The guide blocks 25 are slidably connected to the guide rails 26. When the top plate 22 moves up and down, the guide blocks 25 can slide along the guide rails 26.

[0046] In this embodiment, the abutment block 18 is made of rubber, and the anti-slip pad 23 is made of sponge.

[0047] In this embodiment, the tensioning fixture clamps and releases the fabric edges during the following process:

After the components on the support frame 1 are moved to the required position by the transverse sliding rail, the piston rod of the lifting cylinder 9 extends and drives the top plate 22 to rise. The top claw 8 connected to the top plate 22 pushes the edge of the fabric to rise. When the top claw 8 rises to the highest position, the piston rod of the pressing cylinder 16 extends and pushes the abutment plate 17 down through the abutment block 18. The suction plate 4 connected to the abutment plate 17 will flip down until the lower side of the suction plate 4 contacts the upper side of the fabric edge. At this time, the edge of the fabric is located between the suction plate 4 and the top claw 8. Then, the air in the suction chamber 5 of the suction plate 4 can be drawn out through the external air pipe, so that the suction chamber 5 forms a negative pressure, thereby adsorbing the edge of the fabric to the lower side of the suction plate 4. At this time, the edge of the fabric is fixed between the suction plate 4 and the top claw 8. When both sides of the fabric are fixed, the section of fabric is in a taut state.

[0049] When the edge clamping mechanism needs to loosen the edge of the fabric, the piston rod of the lifting cylinder 9 retracts, causing the top claw 8 to descend, and the piston rod of the pressing cylinder 16 also retracts, causing the suction plate 4 to flip upward, so that the edge of the fabric can detach from the suction plate 4 and fall down.

[0050] The advantage of this embodiment is that the edge of the membrane-split fiber fabric is fixed by the suction plate and the top claw. The suction plate provides some force, which can reduce the compression of the fabric and thus reduce the deformation and damage of the fabric edge.

[0051] The above specific embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
