Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a trimming device for antistatic fabrics. Background Technology

[0002] Antistatic fabrics are functional textiles designed through special processes or materials to effectively prevent or reduce the accumulation and discharge of static electricity. Their core function is to conduct away, neutralize or dissipate charges, thus preventing static electricity from harming the human body, equipment, environment or production process. They are widely used in fields sensitive to static electricity, such as electronics, chemicals, medical, petroleum, and precision instruments.

[0003] In the production process of antistatic fabrics, the trimming process is a key step to ensure product quality. Its main purpose is to remove excess burrs, wrinkles and non-compliant parts from the fabric edges to ensure uniform width. Currently, hot cutting blades have become a commonly used trimming equipment in the industry due to their advantage of using high-temperature blades to melt the fabric edges and simultaneously melt the fiber ends to form a sealed edge, thereby effectively preventing burrs and conductive fibers from being exposed.

[0004] However, hot cutting blades have significant drawbacks during use. Because the hot cutting process requires heating the blade to a high temperature, the fibrous melt generated during cutting has high viscosity due to the high temperature, and it is very easy to adhere to the blade surface. Especially when the blade temperature is too high or the cutting speed is too slow, the melt retention phenomenon is particularly serious. These retained fiber residues will continuously wear down the blade, making it gradually dull, which will lead to quality problems such as burrs, melt beads, and uneven cutting in subsequent cutting. In view of this, this application proposes a trimming device for antistatic fabrics. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a trimming device for antistatic fabrics to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a trimming device for antistatic fabrics, comprising a processing table, two symmetrically distributed front-to-back correction rollers arranged on the left side of the top of the processing table, a first bearing seat mounted on the top of the processing table being fitted onto the rotating shafts at both ends of the two correction rollers, a recessed area extending from front to back being formed at the right side of the top of the processing table, a material collection trough being formed at the bottom of the recessed area, a rotatable first rotating roller being arranged on the top of the processing table and on both sides of the recessed area, a second bearing seat mounted on the top of the processing table being fitted onto the rotating shafts at both ends of the two first rotating rollers, an adjustment mechanism being installed at the bottom of both sides of the inner wall of the recessed area, two trimming mechanisms capable of relative movement being fitted onto each adjustment mechanism, and a second rotating roller being rotatably installed between the front and rear sides of the material collection trough.

[0007] Optionally, the bottom of the material collection trough is set as an inclined surface, and the left side of the material collection trough is set as an opening that extends to the left side of the processing table. A through-hole is opened at the center of the top of both the front and rear sides of the material collection trough, and a positioning bearing is fixedly installed in both through-holes. The rotating shafts at both ends of the second rotating roller are respectively fixedly inserted between the inner ring walls of the two positioning bearings.

[0008] Optionally, motor mounts are fixedly installed on both sides of the left end of the processing table, and a third motor is installed on the top of each of the two motor mounts. A transmission assembly is provided between the output end of each of the two third motors and the shaft of the corresponding straightening roller. A photoelectric sensor is installed on the top of the processing table and to the left of the straightening roller, and a PLC controller is installed on the left end of the processing table. The photoelectric sensor and the two third motors are linearly connected to the PLC controller. The two straightening rollers are inclined on the horizontal plane and are distributed in an inclined V-shape on the top of the processing table.

[0009] Optionally, the adjustment mechanism includes two third bearing seats, a rotating rod, a first motor, a second motor, and a screw. The two third bearing seats are respectively installed on the front and rear sides of the bottom of the recessed area. The rotating rod is fixedly inserted between the two third bearing seats. The first motor is fixedly installed on the outside of the front third bearing seat, and the output end of the first motor is fixedly connected to one end of the rotating rod. The side wall of the rotating rod has a through slot. The second motor is fixedly installed on the other end of the rotating rod, and a screw extending into the slot is fixedly connected to the output end of the second motor. The two ends of the screw are respectively set as a positive thread and a negative thread.

[0010] Optionally, the trimming mechanism includes a collar, a handle, a blade, hydraulic rods, and a cleaning plate. The collar is fitted onto the rotating rod, and a threaded hole is provided at the center of the side of the collar. The threaded hole on the side of the collar is threaded onto the screw rod. The handle is fixedly installed on the outer wall of the collar, and the blade is installed at the end of the handle. Hydraulic rods are installed on both sides of the handle, and a cross-shaped cleaning plate is fixedly installed at the telescopic ends of the two hydraulic rods. The side of the cleaning plate has a groove that matches the size of the blade, and the groove on the cleaning plate fits onto the blade and contacts the handle.

[0011] Optionally, the collars in the two sets of trimming mechanisms on the rotating rod are connected to the positive thread portion and the negative thread portion of the screw, respectively.

[0012] Optionally, the blade of the knife body in the left trimming mechanism is located at the top, and the blade of the knife body in the right trimming mechanism is located at the bottom. When the trimming mechanism is in a horizontal state, the blades in the trimming mechanism can contact the fabric that passes over the first and second rotating rollers.

[0013] Optionally, the transmission assembly includes two sprockets and a chain. The two sprockets are respectively mounted on the shaft at the output end of the third motor and one end of the correction roller, and the chain drive is sleeved between the two sprockets.

[0014] The beneficial effects of this utility model are:

[0015] By controlling the second motor in the adjustment mechanism, the screw can be driven to rotate in the threaded holes on the two collars, thereby adjusting the distance between the two trimming mechanisms. This facilitates trimming fabrics of different widths. During the trimming process, the trimming mechanism on one side of the recessed area trims the fabric. After the heat-melted fibers adhere to the blade in the trimming mechanism, the first motor in the other adjustment mechanism is controlled to drive the rotating rod to rotate. The trimming mechanism on the rotating rod is in a horizontal state and in contact with the fabric. Then, the original adjustment mechanism is controlled to separate the trimming mechanism from the fabric, allowing the trimming mechanisms on both sides of the recessed area to alternately trim the edge of the fabric.

[0016] When the trimming mechanism with the hot melt fiber is not in contact with the fabric, it is left to stand for a certain period of time to allow the hot melt fiber to solidify. Then, the cleaning plate is driven to move back and forth along the outside of the blade body by controlling the hydraulic rod. Through the blade groove that fits against the outer wall of the blade body, the fabric residue adhering to the surface of the blade body can be effectively removed. The solidified hot melt fiber is easier to remove under force and will not stick to the cleaning plate.

[0017] Two horizontally inclined correction rollers rotate clockwise, which not only conveys the fabric but also spreads the fabric to both sides when rotating outward. When the fabric deviates, photoelectric sensors can quickly detect it and control the speed of two third motors through the PLC controller. The different rotation speeds of the two correction rollers create a speed difference. The lateral tension and friction generated by this speed difference can effectively push the fabric to deviate in the specified direction, thereby achieving fabric correction.

[0027] 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.

[0028] Please see Figures 1-7 This utility model provides a technical solution: a trimming device for antistatic fabrics, including a processing table 1. Two symmetrically arranged straightening rollers 4 are disposed on the left side of the top of the processing table 1. First bearing seats 5 are fitted onto the rotating shafts at both ends of the two straightening rollers 4 and mounted on the top of the processing table 1. A through-type recessed area 2 is formed on the right side of the top of the processing table 1. A material collection groove 3 is formed at the bottom of the recessed area 2. Rotatable first rotating rollers 6 are disposed on the top of the processing table 1 and on both sides of the recessed area 2. The rotating shafts at both ends of the moving roller 6 are fitted with second bearing seats 7 installed on the top of the processing table 1. Adjustment mechanisms 8 are installed at the bottom of both sides of the inner wall of the recessed area 2. Two trimming mechanisms 9 that can move relative to each other are fitted on each set of adjustment mechanisms 8. A second rotating roller 11 is rotatably installed between the front and rear sides of the material collection trough 3. Through two horizontally inclined correction rollers 4, the correction and flattening of the fabric can be completed simultaneously. The two sets of adjustment mechanisms 8 can not only alternately trim the edge of the fabric, but also adjust the angle of the trimming mechanism 9.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the bottom of the material collection trough 3 is set as an inclined surface, and the left side of the material collection trough 3 is set as an opening that extends to the left side of the processing table 1. The center of the top of the front and rear sides of the material collection trough 3 is provided with a through-hole, and a positioning bearing 10 is fixedly installed in both through-holes. The rotating shafts at both ends of the second rotating roller 11 are respectively fixedly inserted between the inner ring walls of the two positioning bearings 10. The fabric cut off by the trimming mechanism 9 will fall directly into the material collection trough 3, and then be discharged from the opening at the left end along the inclined surface at the bottom of the material collection trough 3. The two positioning bearings 10 can play a role in positioning the position of the second rotating roller 11.

[0030] like Figure 1 and Figure 2 As shown, motor mounts 12 are fixedly installed on both sides of the left end of the processing table 1. A third motor 13 is installed on the top of each of the two motor mounts 12. A transmission assembly 14 is provided between the output end of each of the two third motors 13 and the shaft of the corresponding straightening roller 4. A photoelectric sensor 15 is installed on the top of the processing table 1 and to the left of the straightening roller 4. A PLC controller 16 is installed on the left end of the processing table 1. The photoelectric sensor 15 and the two third motors 13 are linearly connected to the PLC controller 16. The two straightening rollers 4 are inclined on the horizontal plane and are arranged in an inverted V-shape on the top of the processing table 1. By adjusting the speed of the two third motors 13 with the two horizontally inclined straightening rollers 4, the straightening and flattening of the fabric can be completed synchronously.

[0031] like Figure 1 and Figure 2 As shown, the adjustment mechanism 8 includes two third bearing seats 81, a rotating rod 82, a first motor 83, a second motor 85, and a screw 86. The two third bearing seats 81 are respectively installed on the front and rear sides of the bottom of the recessed area 2. The rotating rod 82 is fixedly inserted between the two third bearing seats 81. The first motor 83 is fixedly installed on the outside of the front third bearing seat 81, and the output end of the first motor 83 is fixedly connected to one end of the rotating rod 82. The side wall of the rotating rod 82 has a through slot 84. The second motor 85 is fixedly installed on the other end of the rotating rod 82, and the output end of the second motor 85 is fixedly connected to a screw 86 extending into the slot 84. The two ends of the screw 86 are respectively set as a positive thread and a negative thread. By controlling the first motor 83 in the adjustment mechanism 8, the rotating rod 82 can be driven to rotate at an angle, while the operation of the second motor 85 at the other end of the rotating rod 82 will drive the screw 86 to rotate in the slot 84 on the rotating rod 82.

[0032] like Figure 6 and Figure 7As shown, the trimming mechanism 9 includes a collar 91, a handle 92, a blade body 93, hydraulic rods 94, and a cleaning plate 95. The collar 91 is sleeved on the rotating rod 82, and a screw hole 911 is provided at the center of the side of the collar 91. The screw hole 911 on the side of the collar 91 is threaded onto the screw rod 86. The handle 92 is fixedly installed on the outer wall of the collar 91, and the blade body 93 is installed at the end of the handle 92. Hydraulic rods 94 are installed on both sides of the handle 92, and cross-shaped cleaning plates are fixedly installed at the telescopic ends of the two hydraulic rods 94. The cleaning plate 95 has a groove 96 on its side that matches the size of the blade body 93. The groove 96 on the cleaning plate 95 is fitted onto the blade body 93 and contacts the handle 92. When the trimming mechanism rotates to a position where it does not contact the fabric, the blade body 93 is left to stand still for a preset time. Then, the cleaning plate 95 is driven to move back and forth along the outside of the blade body 93 by controlling the hydraulic rod 94. This effectively removes the fabric residue adhering to the surface of the blade body 93, preventing the adhering fabric residue from affecting the quality of the fabric trimming during subsequent trimming processes.

[0033] like Figure 5 and Figure 6 As shown, the collars 91 in the two sets of trimming mechanisms 9 on the rotating rod 82 are connected to the positive thread and the negative thread of the screw 86, respectively. By rotating the screw 86, the positive thread and the negative thread of the screw 86 can rotate with the screw holes 911 on the two sleeves 91, thereby driving the two collars 91 to move relative to each other on the screw 86.

[0034] like Figure 1 and Figure 2 As shown, the blade of the knife body 93 in the left trimming mechanism 9 is located at the top, and the blade of the knife body 93 in the right trimming mechanism 9 is located at the bottom. When the trimming mechanism 9 is in a horizontal state, the knife bodies 93 in the trimming mechanism 9 can contact the fabric that passes over the first rotating roller 6 and the second rotating roller 11. The knife body 93 with the blade at the top is convenient for cutting the fabric moving downward on the left, while the knife body 93 with the blade at the bottom is convenient for cutting the fabric moving upward on the right.

[0035] like Figure 1 and Figure 2 As shown, the transmission assembly 14 includes two sprockets and a chain. The two sprockets are respectively mounted on the shaft at the output end of the third motor 13 and one end of the straightening roller 4, and the chain drive is sleeved between the two sprockets.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
