Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a nonwoven fabric winding clamping fixture. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or thermal rolling, and finally finishing processes. It is characterized by its moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, odorless, inexpensive, and recyclable properties. After production, nonwoven fabric needs to be rolled up.

[0003] Chinese utility model patent CN220364083U discloses a nonwoven fabric winding fixture, including a worktable. The top of the worktable is fixed with a first side plate, a second side plate, and a connecting plate, and has a through hole. A rotating rod is movably connected to the side of the first side plate. One end of the rotating rod is fixed with a first gear, and the other end is connected to a winding mechanism via a first circular plate. A first bearing is fixed to the side of the connecting plate, and a circular rod is connected to the first bearing. A first transmission wheel is fixed to the circular rod, and a second gear meshing with it is fixed to the other end of the circular rod. A drive motor is mounted on the bottom of the worktable via a straight plate, and its output end is connected to the second transmission wheel. The second transmission wheel and the first transmission wheel are connected via a conveyor belt passing through the through hole. The driving method of the winding mechanism in the above-mentioned nonwoven fabric winding fixture will not damage the output end of the drive motor, ensuring its service life.

[0004] When the nonwoven fabric winding fixture disclosed in the above-mentioned utility model patent is used, the nonwoven fabric is wound on the winding roller as the winding roller rotates. Since the friction between the nonwoven fabric and the winding roller is limited and it is difficult to ensure that the nonwoven fabric is tightly attached to the winding roller during winding, the nonwoven fabric will spin on the winding roller during the winding process, which affects the winding efficiency of the nonwoven fabric. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a nonwoven fabric winding clamping fixture, which solves the problem that the nonwoven fabric spins idly on the winding roller during the winding process, affecting the winding efficiency of the nonwoven fabric.

[0006] According to an embodiment of this utility model, a nonwoven fabric winding clamping fixture includes a base, on which a winding roller, a first seat body, a second seat body, and a pressing strip are provided. The first seat body and the second seat body are respectively disposed at opposite ends of the winding roller and are detachably connected to the winding roller. The first seat body and the second seat body are respectively rotatably connected to the base. The outer peripheral wall of the winding roller is provided with a groove for accommodating the pressing strip, and the first seat body is provided with a slot aligned with the groove. The first seat body is also provided with a limiting hole communicating with the slot, and a pressing block is provided in the limiting hole. The first seat body is also provided with a threaded part and a pressing knob that cooperates with the threaded part. The threaded part is arranged around the opening of the limiting hole, and the pressing knob covers the opening of the limiting hole. A pressing spring is provided between the pressing knob and the pressing block. The pressing spring drives the pressing block to abut against the pressing strip and presses the pressing strip onto the first seat body.

[0007] Furthermore, the second seat is provided with a mounting rod and the first seat is provided with a positioning hole that cooperates with the mounting rod, and the take-up roller is provided with a through hole for the mounting rod to pass through.

[0008] Furthermore, the first base is provided with a first receiving groove for accommodating part of the take-up roller, and a first positioning protrusion is provided in the first receiving groove. The outer peripheral wall of the take-up roller is provided with a first positioning groove that cooperates with the first positioning protrusion.

[0009] Furthermore, the second seat is provided with a second receiving groove for accommodating part of the take-up roller, and one end of the pressing bar away from the first seat extends into the second receiving groove. The second receiving groove is provided with a second positioning protrusion, and the outer peripheral wall of the take-up roller is provided with a second positioning groove that cooperates with the second positioning protrusion.

[0010] Furthermore, one end of the clamping strip extends out of the slot, and the end of the clamping strip outside the slot has a bent portion, which extends away from the first seat.

[0011] Furthermore, the end of the pressure block near the pressure strip is provided with an arc-shaped surface, which is in contact with the pressure strip.

[0012] Furthermore, the clamping knob is provided with anti-slip texture, which is arranged along the circumference of the clamping knob.

[0013] Furthermore, the base is provided with a through slot, which is located on the side of the slot away from the groove.

[0014] Furthermore, the base is symmetrically provided with two rotatable mounting seats, and the sides of the first and second bases that are far apart from each other are respectively provided with mounting parts, and the mounting seats are provided with mounting grooves that cooperate with the mounting parts.

[0015] Furthermore, the mounting part is provided with a through hole, and the mounting groove is provided with a mounting hole aligned with the through hole.

[0016] Compared with the prior art, this utility model has the following beneficial effects: By using a rotating take-up roller on the base to take up the non-woven fabric, the end of the non-woven fabric is first placed into the groove on the take-up roller during take-up. Then, the clamping strip is inserted into the groove from the slot and positioned above the non-woven fabric to clamp the non-woven fabric between the clamping strip and the take-up roller. After the clamping strip is moved into place, the clamping knob is rotated so that the clamping block abuts against the clamping strip under the elastic force provided by the clamping spring. At this time, the clamping strip is pressed against the first base by the clamping block, which can fix the position of the clamping strip and thus clamp the end of the non-woven fabric. When the non-woven fabric is taken up by the rotation of the take-up roller, it can prevent the non-woven fabric from slipping relative to the take-up roller and causing it to spin freely. It solves the technical problem that the non-woven fabric spins freely on the take-up roller during the take-up process, which affects the take-up efficiency of the non-woven fabric. It produces the technical effect of ensuring that the non-woven fabric is quickly wound on the take-up roller. Moreover, it is simple to operate and easy to use. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a nonwoven fabric winding clamping fixture, which is used to clamp the ends of the nonwoven fabric when winding it after the nonwoven fabric production is completed, so that the nonwoven fabric can be quickly wound onto the roller.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 The nonwoven fabric winding clamping fixture includes a base 1, on which a winding roller 2, a first seat 3, a second seat 4, and a clamping strip 5 are provided. The first seat 3 and the second seat 4 are respectively disposed at opposite ends of the winding roller 2 and detachably connected to the winding roller 2. The first seat 3 and the second seat 4 are rotatably connected to the base 1, allowing the winding roller 2 to rotate on the base 1. The outer peripheral wall of the winding roller 2 has a groove 21 for accommodating the clamping strip 5, and the first seat 3 has a slot 31 aligned with the groove 21. The groove 21 is used to accommodate the end of the nonwoven fabric to be wound. The clamping strip 5 extends from the slot 31 into the groove 21 and clamps the end of the nonwoven fabric. The nonwoven fabric is pressed into the groove 21. The first seat 3 is also provided with a limiting hole 32 communicating with the slot 31 and a pressure block 6 is provided in the limiting hole 32. The first seat 3 is also provided with a threaded part 33 and a pressing knob 7 that cooperates with the threaded part 33. The threaded part 33 is arranged around the opening of the limiting hole 32 and the pressing knob 7 covers the opening of the limiting hole 32. A pressing spring 8 is provided between the pressing knob 7 and the pressure block 6. By rotating the pressing knob 7, the pressing spring 8 drives the pressure block 6 to abut against the pressing strip 5 and presses the pressing strip 5 onto the first seat 3, thereby fixing the position of the pressing strip 5 so that the nonwoven fabric is clamped between the pressing strip 5 and the take-up roller 2.

[0026] Specifically, the operation steps for winding nonwoven fabric using the nonwoven fabric winding clamping fixture provided in this embodiment are as follows: First, place the end of the nonwoven fabric to be wound into the groove 21 on the winding roller 2. Then, extend the clamping strip 5 from the slot 31 into the groove 21, with the clamping strip 5 positioned above the nonwoven fabric to clamp it between the clamping strip 5 and the winding roller 2. After moving the clamping strip 5 into place, rotate the clamping knob 7 so that the pressure block 6 abuts against the clamping strip 5 under the elastic force provided by the clamping spring 8. At this time, the clamping strip 5 is pressed against the first seat 3 by the pressure block 6, which can fix the position of the clamping strip 5, thereby clamping the end of the nonwoven fabric. Then, rotate the winding roller 2. Roller 2 can wind up the nonwoven fabric and prevent the nonwoven fabric from slipping relative to the winding roller 2 and spinning freely. After winding, the first seat 3 and the second seat 4 can be removed from the base 1 to remove the winding roller 2 along with the wound nonwoven fabric from the base 1. When it is necessary to remove the nonwoven fabric from the winding roller 2, first turn the clamping knob 7 in the opposite direction to extend the clamping spring 8 to reduce the elastic force generated by the clamping spring 8 on the pressure block 6, thereby releasing the lock on the clamping strip 5. Then, pull the clamping strip 5 out of the groove 21 to move the clamping strip 5 away from the nonwoven fabric. Finally, remove the first seat 3 or the second seat 4 from the winding roller 2 to pull the winding roller 2 out of the nonwoven fabric. The nonwoven fabric winding clamping fixture provided in this embodiment can prevent the nonwoven fabric from spinning freely on the winding roller 2 during the winding process, thus ensuring that the nonwoven fabric is quickly wound onto the winding roller 2 for winding. It is also simple to operate and easy to use.

[0027] like Figure 2 and Figure 5 As shown, the second base 4 is provided with a mounting rod 41, and the first base 3 is provided with a positioning hole 34 that mates with the mounting rod 41. The take-up roller 2 is provided with a through hole 22 through which the mounting rod 41 passes. When assembling the first base 3, the take-up roller 2, and the second base 4, the mounting rod 41 is passed through the through hole 22 and mates with the positioning hole 34 to install the take-up roller 2 between the first base 3 and the second base 4, ensuring that the first base 3 and the second base 4 respectively mate with the end of the take-up roller 2, facilitating the assembly of the nonwoven fabric winding clamping fixture.

[0028] Please combine Figure 3 , Figure 4 and Figure 5The first base 3 is provided with a first receiving groove 35 to accommodate part of the take-up roller 2, and a first positioning protrusion 36 is provided in the first receiving groove 35. The outer peripheral wall of the take-up roller 2 is provided with a first positioning groove 23 that cooperates with the first positioning protrusion 36. The first receiving groove 35 is provided at the end of the first base 3 to accommodate part of the take-up roller 2, and the first positioning protrusion 36 that cooperates with the first positioning groove 23 on the take-up roller 2 is provided in the first receiving groove 35. This helps to improve the reliability of the cooperation between the first base 3 and the take-up roller 2, and at the same time ensures that the slot 31 is aligned with the groove 21, so that the pressing strip 5 can be smoothly inserted from the slot 31 into the groove 21.

[0029] In detail, the second seat 4 is provided with a second receiving groove 42 to accommodate part of the take-up roller 2, and the end of the pressing strip 5 away from the first seat 3 extends into the second receiving groove 42. The second receiving groove 42 is provided with a second positioning protrusion 43, and the outer peripheral wall of the take-up roller 2 is provided with a second positioning groove 24 that cooperates with the second positioning protrusion 43. The second receiving groove 42 provided on the second seat 4 is used to accommodate part of the take-up roller 2, and the second seat 4 and the take-up roller 2 are connected by the cooperation of the second positioning protrusion 43 and the second positioning groove 24, so that the second seat 4 and the take-up roller 2 are firmly connected. After the pressing strip 5 is inserted into the groove 21, its end away from the first seat 3 extends into the second receiving groove 42, which can further improve the stability of the pressing strip 5 on the take-up roller 2 and prevent the pressing strip 5 from accidentally detaching from the take-up roller 2 during the winding process.

[0030] Please refer to Figure 2 and Figure 3 One end of the clamping strip 5 extends out of the slot 31, and the end of the clamping strip 5 outside the slot 31 has a bent portion 51, which extends away from the first seat 3. The bent portion 51 is provided at the end of the clamping strip 5. When the clamping strip 5 moves into the groove 21 until the bent portion 51 is in contact with the first seat 3, the clamping strip 5 is fully inserted into the groove 21. This facilitates control of the movement stroke of the clamping strip 5, and the clamping strip 5 can be easily pulled out of the groove 21 by pulling the bent portion 51, facilitating the use of the nonwoven fabric winding clamping fixture.

[0031] In this embodiment, the pressure block 6 has an arc-shaped surface at one end near the pressure strip 5, and the arc-shaped surface fits into the pressure strip 5. When the pressure block 6 abuts against the pressure strip 5, the arc-shaped surface fits into the surface of the pressure strip 5, making the fit between the pressure block 6 and the pressure strip 5 reliable and preventing the pressure strip 5 from loosening during the winding process.

[0032] like Figure 3 As shown, the clamping knob 7 is provided with anti-slip texture 71, which is arranged along the circumference of the clamping knob 7. The anti-slip texture 71 is provided on the clamping knob 7 to facilitate the operation of the clamping knob 7 and to make the non-woven fabric winding clamping fixture easy to control.

[0033] like Figure 1 and Figure 2 As shown, the base 1 has a through slot 11, which is located on the side of the slot 31 away from the groove 21. The slot 11 is used for the clamping strip 5 to pass through, so as to facilitate the movement of the clamping strip 5 when the take-up roller 2 is installed on the base 1, and to prevent the base 1 from blocking the movement of the clamping strip 5.

[0034] Please combine Figure 2 and Figure 4 The base 1 has two symmetrically arranged rotatable mounting seats 9. The sides of the first seat 3 and the second seat 4 that are far apart from each other are respectively provided with mounting portions 37, and the mounting seats 9 are provided with mounting grooves 91 that cooperate with the mounting portions 37. The mounting seats 9 are provided on the base 1 for mounting the first seat 3 and the second seat 4. The first seat 3 and the second seat 4 are mounted onto the base 1 by inserting the mounting portions 37 on the first seat 3 and the second seat 4 into the mounting grooves 91 on the corresponding mounting seats 9. When the mounting seats 9 rotate relative to the base 1, they drive the first seat 3 and the second seat 4 to rotate, thereby allowing the winding roller 2 to rotate on the base 1 and perform the winding operation of the nonwoven fabric.

[0035] Specifically, the mounting part 37 is provided with a through hole 38, and the mounting groove 91 is provided with a mounting hole aligned with the through hole 38. The mounting part 37 and the mounting base 9 are fixedly connected by bolts, nuts, and other connecting parts 92. By passing the bolts through the through hole 38 and the mounting hole in sequence and tightening them with nuts, the mounting part 37 can be fixed in the mounting groove 91, ensuring a reliable connection between the first base body 3 and the second base body 4 and the mounting base 9, and facilitating the disassembly and assembly of the first base body 3 and the second base body 4, so as to remove the wound nonwoven fabric from the base body.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions 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 solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
