Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a wear-resistant carding machine feed roller. Background Technology

[0002] Carding machines are important equipment in the textile, non-woven fabric and chemical fiber processing fields. They are mainly used for opening, removing impurities and uniformly mixing fiber raw materials. The feeding roller of the carding machine is a key component used to control the input of fiber raw materials. Its core function is to uniformly hold and transport the fiber raw materials to the subsequent carding process.

[0003] The existing patent with authorization announcement number "CN222809620U" discloses a wear-resistant textile roller, which includes a drafting roller shaft. Carding sleeves are fitted onto the outer walls of both ends of the drafting roller shaft. Grooves are formed on the outer surfaces of both ends of the drafting roller shaft, and a locking structure is provided at one end of each groove. Limiting rings are fixedly installed on the left and right sides of the middle outer wall of the drafting roller shaft. The wear-resistant textile roller of this utility model features a carding sleeve and a drafting roller shaft, which are detachably connected. This facilitates the individual disassembly of the carding sleeve, reducing usage costs. The locking structure allows for easy positioning of the carding sleeve, making it easy to install and disassemble.

[0004] However, this device has the following shortcomings:

[0005] 1. When the feeding roller is in use, static electricity is generated by the friction between its surface and the fiber when conveying the fiber raw material. Static electricity will cause the wear between the roller and the fiber to be accelerated, reducing the service life of the roller. The above-mentioned device is difficult to reduce the discharge of static electricity on the roller surface during use, which reduces the wear resistance of the roller.

[0006] 2. When the above-mentioned device is in use, it is difficult to remind the staff to replace the rubber layer after the rubber layer on the roller surface is worn, which makes the roller body easy to wear and reduces the service life of the roller. Utility Model Content

Electrical contact A is located at the bottom of each movable plate. Electrical contact B, which mates with electrical contact A, is located at the bottom of the inner side of each set of sleeves. Indicator lights are provided on both sides of the top of the mounting frame to ensure the conductive wheel remains in contact with the rubber layer. When the rubber layer wears, the indicator lights automatically activate to remind workers to replace the rubber layer.

[0011] Preferably, the mounting bracket has through holes on both sides that communicate with the slide groove, and the grounding wire passes through the through holes to provide a wiring channel for the grounding wire.

[0012] Preferably, one side of the grounding wire passes through the connecting rod, movable block, and slider and is connected to the ground, which can conduct static electricity to the ground to eliminate it and reduce the static interference experienced by the roller.

[0014] Preferably, the conductive slip ring is a cap-type slip ring, and the inner side of the conductive wheel is provided with a conductive sheet that cooperates with the conductive slip ring, which can absorb and discharge static electricity from the conductive wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the abrasion-resistant carding machine has a feed roller;

[0016] 1. Through the cooperation between the chute, slider, movable block, connecting rod, conductive wheel, and conductive slip ring, the conductive wheel can roll along the surface of the rubber layer when the fiber is fed into the carding machine. This continuously absorbs the static electricity generated by the friction between the rubber layer and the fiber, preventing the accumulation of charge from causing increased wear on the roller body, reducing the friction damage to the roller, and thus improving the wear resistance of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 The present invention provides an embodiment of a wear-resistant carding machine feed roller, including a mounting frame 1, a roller roller body 21 sleeved on the inner side of the mounting frame 1, a rubber layer 22 provided on the outer side of the roller roller body 21, and a wear-resistant coating provided on the outer side of the rubber layer 22, wherein the wear-resistant coating is a ceramic coating, which can improve the wear resistance of the rubber layer 22. Static discharge components 3 are provided on both sides of the inner side of the mounting frame 1, and a reminder component 4 is provided on the top of the inner side of the mounting frame 1.

[0024] The static electricity discharge assembly 3 includes a slide 31, a slider 32, a movable block 33, a connecting rod 34, a conductive wheel 35, a conductive slip ring 36, and a grounding wire 37. The slide 31 has two sets, which are located on both sides of the inner side of the mounting frame 1. The slider 32 is fitted inside the two sets of slide 31, and the movable block 33 is provided on the two sets of sliders 32. The connecting rod 34 is provided on the side of the two sets of movable blocks 33 that are close to each other. The conductive wheel 35 that cooperates with the roller body 21 is fitted outside the two sets of connecting rods 34. The conductive slip ring 36 is provided on the side of the two sets of connecting rods 34 that are close to each other, and the two sets of conductive slip rings 36 are fitted inside the conductive wheel 35. The conductive slip ring 36 is a cap-type slip ring. The conductive plate that cooperates with the conductive slip ring 36 is provided inside the conductive wheel 35, which can absorb and discharge static electricity from the conductive wheel 35.

[0025] Two sets of conductive slip rings 36 are provided with grounding wires 37 on the opposite side. One side of the grounding wire 37 passes through the connecting rod 34, movable block 33 and slider 32 and is connected to the ground. This can conduct static electricity to the ground and eliminate it, reducing the static interference on the roller. The mounting bracket 1 has through holes on both sides that are connected to the slide groove 31. The grounding wire 37 passes through the through holes, which can provide a wiring channel for the grounding wire 37.

[0026] The reminder component 4 includes a sleeve 41, a sleeve rod 42, a movable plate 43, a spring 44, an electrical contact A 45, an electrical contact B 46, and an indicator light 47. Two sets of sleeves 41 are provided, located on the top of the inner side of the mounting frame 1. A sleeve rod 42 connected to the movable block 33 is fitted onto the bottom of each set of sleeves 41. A movable plate 43 is provided on the top of each set of sleeve rods 42. A spring 44 connected to the sleeve 41 is provided on the top of each set of movable plates 43. An electrical contact A 45 is located at the bottom of each set of movable plates 43. An electrical contact B 46, which mates with the electrical contact A 45, is provided on the bottom of the inner side of each set of sleeves 41. Indicator lights 47 are provided on both sides of the top of the mounting frame 1 to ensure that the conductive wheel 35 remains in contact with the rubber layer 22. When the rubber layer 22 wears, the indicator lights 47 automatically activate to remind the operator to replace the rubber layer 22.

[0027] Working principle: When in use, this device can be installed at the feeding port of the carding machine. It is connected to the roller body 21 through an external drive component. Driving the roller body 21 to rotate can utilize the friction between the rubber layer 22 and the feed fiber to drive the fiber to feed evenly.

[0028] When the roller body 21 rotates, the conductive wheel 35 can roll along the outer side of the rubber layer 22. Through the contact between the conductive wheel 35 and the roller body 21, the static electricity generated by the roller body 21 when conveying the fiber raw material can be transferred to the conductive wheel 35, and then transferred to the conductive slip ring 36 through the conductive wheel 35. The conductive slip ring 36 can then be connected to the ground through the connecting rod 34 to conduct the static electricity to the ground, thereby reducing the rapid wear of the rubber layer 22 due to static interference and improving the wear resistance of the device.

[0029] When the rubber layer 22 wears and becomes thin, the spring force of the spring 44 can push the sleeve rod 42 down, which in turn can drive the movable block 33 down, so that the conductive wheel 35 is always in contact with the rubber layer 22, ensuring the static electricity discharge effect. At the same time, when the rubber layer 22 is worn and unusable, the movable plate 43 can drive the electric contact block A45 down to contact the electric contact block B46, thereby activating the indicator light 47 to remind the staff to replace the rubber layer 22 and prevent damage to the roller body 21.
