Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically to a carding roller transfer tool. Background Technology

[0002] The carding machine is a key piece of equipment in textile production, its function being to comb and remove impurities from fibers, forming a uniform cotton web. The licker-in roller is an important component of the carding machine; its surface is covered with metal card cloth, and it rotates at high speed during operation to open and initially comb the cotton layer. During routine maintenance, upkeep, or card cloth replacement, the licker-in roller needs to be frequently removed from the machine and reinstalled after repairs. Currently, traditional operating methods mainly have the following problems:

[0003] Because the licker-in roller itself has a slender cylindrical structure, it is heavy (usually weighing tens of kilograms), its surface is covered with sharp needles, and its center of gravity is difficult to control. During disassembly and transfer, it usually requires 2-3 operators to work together to move it by hand. This method is not only extremely labor-intensive, but also very prone to accidents such as operators' hands being cut by the needles or being injured by falling needles. There is also a risk of the licker-in roller being damaged by collision. Utility Model Content

[0004] The purpose of this invention is to provide a carding roller transfer fixture that avoids direct contact between the operator and the carding roller with sharp needles, fundamentally eliminating the risk of hand cuts and injuries from falling heavy objects, and achieving safe transfer of the carding roller.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A carding roller transfer fixture includes a load-bearing crossbeam frame, a mounting seat and a displacement drive mechanism for driving the mounting seat to move horizontally on the load-bearing crossbeam frame, a mounting frame below the mounting seat, a lifting mechanism for driving the mounting frame to rise and fall on the mounting seat, two L-shaped support frames symmetrically arranged on the mounting frame, a spacing adjustment mechanism for adjusting the distance between the two L-shaped support frames on the mounting frame, and a V-shaped support arm fixedly connected to the bottom of the L-shaped support frame.

[0007] Furthermore, the displacement driving mechanism includes a lead screw rotatably connected to the load-bearing crossbeam frame, a lead screw motor for driving the lead screw to rotate is mounted on the load-bearing crossbeam frame, a movable seat is threadedly connected to the lead screw, a slide rod is fixedly connected to the load-bearing crossbeam frame, the slide rod is arranged parallel to the lead screw, the movable seat is slidably sleeved on the slide rod, and the mounting bracket is fixedly connected below the movable seat.

[0008] Furthermore, the lifting mechanism includes a hydraulic cylinder mounted on the movable seat, the piston rod of the hydraulic cylinder driving the mounting frame, and a guide rod vertically fixedly connected to the top of the mounting frame, the guide rod sliding through the mounting frame.

[0009] Furthermore, the spacing adjustment mechanism includes a bidirectional screw that is horizontally rotatably connected to the mounting frame, a drive motor that drives the bidirectional screw to rotate is mounted on the mounting frame, and adjustment seats are threaded to both ends of the bidirectional screw, with the L-shaped support frame fixedly connected to the bottom of the adjustment seats.

[0010] Furthermore, an arc-shaped limiting block is fixedly connected above the opening of the V-shaped support arm.

[0011] Furthermore, a rubber pad is provided on the inner side of the V-shaped support arm, and the surface of the rubber pad is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This application completely replaces the traditional manual handling method. The V-shaped support arm provides stable support for the spiked roller, eliminating the need for operators to directly contact the sharp needle cloth on the surface of the spiked roller, thus preventing safety accidents such as hand cuts and spiked roller slippage and injury. The displacement drive mechanism enables horizontal movement of the mounting base, the lifting mechanism enables vertical adjustment of the mounting frame, and the spacing adjustment mechanism enables the spacing of the two L-shaped support frames to be adapted, which can flexibly match different placement positions and sizes (length, installation height) of the spiked roller.

[0017] like Figure 1 and Figure 2As shown, a carding roller transfer fixture includes a load-bearing crossbeam frame 1. The load-bearing crossbeam frame 1 is provided with a mounting base 2 and a displacement driving mechanism for driving the mounting base 2 to move horizontally. A mounting frame 3 is provided below the mounting base 2. A lifting mechanism for driving the mounting frame 3 to rise and fall is installed on the mounting base 2. Two L-shaped support frames 4 are symmetrically arranged on the mounting frame 3. A spacing adjustment mechanism for adjusting the distance between the two L-shaped support frames 4 is installed on the mounting frame 3. A V-shaped support arm 5 is fixedly connected to the bottom of the L-shaped support frame 4.

[0018] The displacement driving mechanism includes a lead screw 6 rotatably connected to the load-bearing crossbeam frame 1, a lead screw motor 7 for driving the lead screw 6 to rotate is installed on the load-bearing crossbeam frame 1, a movable seat 8 is threadedly connected to the lead screw 6, a slide rod 9 is fixedly connected to the load-bearing crossbeam frame 1, the slide rod 9 is arranged parallel to the lead screw 6, the movable seat 8 is slidably sleeved on the slide rod 9, and the mounting bracket 3 is fixedly connected below the movable seat 8.

[0019] The lifting mechanism includes a hydraulic cylinder 10 mounted on the movable seat 8. The piston rod of the hydraulic cylinder 10 is connected to the mounting frame 3. A guide rod 11 is vertically fixed to the top of the mounting frame 3. The guide rod 11 slides through the mounting frame 3.

[0020] The spacing adjustment mechanism includes a bidirectional screw 12 that is horizontally rotatably connected to the mounting frame 3. A drive motor 13 that drives the bidirectional screw 12 to rotate is mounted on the mounting frame 3. Both ends of the bidirectional screw 12 are threadedly connected to adjustment seats 14. The L-shaped support frame 4 is fixedly connected to the bottom of the adjustment seat 14.

[0021] An arc-shaped limiting block 15 is fixedly connected above the opening of the V-shaped support arm 5. The addition of the arc-shaped limiting block 15, together with the V-shaped support arm 5, forms an "embracing" structure for the journal of the licker roller. It can effectively prevent the licker roller from slipping laterally from the opening of the V-shaped support arm 5 due to accidental shaking during the transfer process, providing additional safety and further improving the safety of tooling operation.

[0022] The inner side of the V-shaped support arm 5 is provided with a rubber pad, and the surface of the rubber pad is provided with anti-slip texture. The rubber pad with anti-slip texture plays multiple protective roles: first, it prevents the metal V-shaped support arm 5 from directly contacting and scratching the precision licker roller journal; second, it increases the friction and prevents the licker roller from rolling or sliding inside the V-shaped support arm 5; third, it has a certain buffering and shock absorption effect, and can avoid rigid impact when fine-tuning the alignment.

[0023] Working principle:

[0024] First, the drive motor 13 drives the bidirectional screw 12 to rotate, causing the two adjusting seats 14 to move closer or further apart, adjusting the distance between the two L-shaped support frames 4 to match the positions of the journals at both ends of the licker-in roller to be transferred. Then, the screw motor 7 drives the screw 6 to rotate, driving the moving seat 8 to move, horizontally moving the V-shaped support arm 5 directly below the licker-in roller. The hydraulic cylinder 10 is activated, causing the mounting frame 2 to lift the V-shaped support arm 5 until the journals at both ends of the licker-in roller are firmly supported on the rubber pads of the V-shaped support arm 5. At this point, the weight of the licker-in roller is entirely borne by the tooling. The screw motor 7 drives the mounting seat 2 to move, and the hydraulic cylinder 10 adjusts the height of the mounting frame 3 to transfer the licker-in roller to the target position (such as a maintenance table or carding machine mounting port). After reaching the target position, the hydraulic cylinder 10 is driven to descend, allowing the licker-in roller to be placed stably in the target position. Finally, the displacement drive mechanism is adjusted in the reverse direction to separate the V-shaped support arm 5 from the licker-in roller, completing the transfer.

[0025] This invention eliminates the need for operators to directly contact the sharp needle cloth of the licker-in roller, preventing hand injuries. The combination of the V-shaped support arm 5, the arc-shaped limiting block 15, and the rubber pad firmly secures the licker-in roller, preventing it from slipping or colliding during transfer, thus completely eliminating the risks of "dropping and hitting" or "damaging the licker-in roller" during manual handling. The displacement, lifting, and spacing adjustment are automated through the screw motor 7, hydraulic cylinder 10, and drive motor 13, eliminating the need for 2-3 people to lift or push, allowing a single person to complete the operation and significantly reducing the physical burden on operators. The spacing adjustment mechanism adapts to licker-in rollers of different lengths, and the lifting mechanism adapts to different placement heights, eliminating the need for special tooling for different specifications of licker-in rollers, making it suitable for various carding machine licker-in roller transfer scenarios.
