Description

Technical Field

[0001] This utility model relates to the field of spinning and carding technology, and more specifically, it relates to a carding device for spinning with a moving licker-in roller. Background Technology

[0002] The licker-in roller and the cylinder are the core carding components of the carding machine. Both are cylindrical rotating components. The licker-in roller uses licker strips to initially loosen and remove impurities from the fibers, while the cylinder uses card cloth to finely card and orient them. The two work together at a specific interval and linear speed ratio to complete the fiber loosening, carding, and transfer process, providing a clean and uniform fiber flow for subsequent processes.

[0003] In traditional designs, the meshing action between the licker-in roller and the cylinder is concentrated in the middle meshing section along the length of the roller body, which is also the main area for fiber combing and transfer. The needles in this area need to continuously withstand the squeezing and friction during the meshing process, which can easily lead to failure problems such as localized needle wear, dulling, and tooth reversal. At the same time, the short fibers and dust generated during combing, especially hard particle impurities, tend to accumulate in the meshing gap. These accumulated impurities will act as "abrasives" during the relative movement of the two, further aggravating the wear rate of the licker-in roller and the needle cloth, and even scratching the surface of the roller body, affecting the stability of equipment operation.

[0004] Therefore, in order to solve the above problems, we propose a carding device for spinning with a moving licker-in roller. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides the following technical solution:

[0006] A carding device for spinning with a movable licker-in roller includes a cylinder disposed within the carding device body and a licker-in roller located on one side of the cylinder. The licker-in roller is movably connected to the carding device body via a support swing arm connected at both ends. A stroke adjustment mechanism is provided at one end of the licker-in roller. The stroke adjustment mechanism includes a second clamping member connected to one end of the licker-in roller. When the licker-in roller rotates around one end of the support swing arm and moves away from the cylinder, the second clamping member can drive the licker-in roller to move axially to change the relative position of the contact end face with the cylinder.

[0007] Furthermore, the spiked roller includes a cylindrical sleeve and a drive rod that passes through the axis of the cylindrical sleeve and drives it to rotate. The two ends of the drive rod are respectively rotatably connected to the support swing arm.

[0008] Furthermore, a limiting protrusion is formed on the surface of the drive rod along the longitudinal direction, and a limiting groove adapted to the limiting protrusion is provided on the inner wall of the through hole at the axis of the cylindrical sleeve, so as to realize the circumferential positioning and cooperation between the cylindrical sleeve and the drive rod.

[0009] Furthermore, a locking disc is provided on one side wall of the cylindrical sleeve, and an annular groove is formed on the circumferential surface of the locking disc. A connecting ring is formed at one end of the second clamping member, and the connecting ring is embedded in the annular groove. The second clamping member is rotatably connected to the cylindrical sleeve through the connecting ring.

[0010] Furthermore, the stroke adjustment mechanism also includes an adjustment component that applies an axial adjustment driving force to the licker roller via the second clamping member.

[0011] Furthermore, the adjustment assembly includes a first clamping member located on the side of the second clamping member away from the spiked roller, an adjustment rod with external threads on its outer wall surface is provided between the two side walls of the first clamping member, and the side wall of the second clamping member away from the spiked roller is threadedly connected to the adjustment rod.

[0012] Furthermore, one end of the adjusting rod is connected to a drive gear, and one side of the convex tooth of the drive gear meshes with an arc-shaped toothed plate. When the drive gear rolls along the surface of the arc-shaped toothed plate, it can drive the adjusting rod to rotate, thereby causing the second clamping member, which is threadedly connected to the adjusting rod, to move axially along the adjusting rod.

[0013] Furthermore, the drive gear passes through a through hole at the shaft center and is mounted on one end of the adjusting rod. A ratchet is fixedly connected to the adjusting rod at the shaft center of the drive gear. An elastic pawl that engages with the ratchet teeth is provided on the side of the drive gear facing the shaft center of the ratchet. Through the engagement of the ratchet and the elastic pawl, the adjusting rod is driven to rotate in only one direction when the drive gear rotates.

[0014] Furthermore, the adjusting rod is provided with a baffle block on one side of the driving gear and a limiting seat on the other side. The driving gear is rotatably connected to the annular flange of the limiting seat through a limiting groove opened on its side wall.

[0015] Furthermore, two arc-shaped grooves are provided on the side wall of the carding device body, and the two ends of the first clamping member extend and pass through the arc-shaped grooves respectively. The first clamping member is connected to the side wall of the carding device body by fasteners. An adjustment hole is also provided on the side wall of the carding device body for adjusting the rotation direction of the adjustment rod.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This invention, by setting a stroke adjustment mechanism, allows the licker roller to move axially along the cylinder as it rotates around the support arm away from the cylinder, changing the relative position of the contact end face with the cylinder. This effectively avoids the meshing action between the licker roller and the cylinder being concentrated in the middle meshing section along the length of the roller body. This means that the wear of the needle teeth is no longer limited to a specific area, but is distributed over a larger area, greatly reducing the probability of failure problems such as wear, dulling, and tooth retraction of local needle teeth due to continuous compression and friction. At the same time, because the licker roller is away from the cylinder, the increased distance between the two improves the accumulation of short fibers and dust from combing and cleaning, slowing down the wear rate of the licker and the needle cloth, preventing the roller surface from being scratched by solid debris, and improving the stability of equipment operation.

[0030] 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 scope of protection of the present utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Please see the appendix Figure 1-9 A carding device for spinning with a movable licker-in roller includes a cylinder 1 disposed within the carding device body 6 and a licker-in roller 2 located on one side of the cylinder 1. The axis of the licker-in roller 2 and the cylinder 1 are parallel to each other and a certain distance is maintained between them to ensure that the fibers can be smoothly opened, carded and transferred between them. The protruding connecting parts at both ends of the licker-in roller 2 are respectively connected to the supporting swing arms 8. The bottom of the two sets of supporting swing arms 8 are respectively rotatably connected to the carding device body 6, so that the licker-in roller 2 can swing around the connecting fulcrum at the bottom of the supporting swing arms 8. When the licker-in roller 2 moves away from the cylinder 1, the distance between the two increases, so that the short fibers, dust and other impurities accumulated in the meshing gap between the two can be more easily cleaned. When it is necessary to restore the normal working state, the licker-in roller 2 can be rotated back to the position close to the cylinder 1 around the supporting swing arms 8.

[0033] like Figure 4As shown, the spiked roller 2 consists of a cylindrical sleeve 201, spikes covering the outer wall of the cylindrical sleeve 201, and a drive rod 203 that passes through the axis of the cylindrical sleeve 201 and drives its rotation. Both ends of the drive rod 203 are rotatably connected to the support arm 8. A stroke adjustment mechanism 3 is provided at one end of the cylindrical sleeve 201, and a drive device is connected to the end of the drive rod 203 away from the stroke adjustment mechanism 3. The drive device can be powered by a motor. The stroke adjustment mechanism 3 includes a second clamping member 302 connected to one end of the cylindrical sleeve 201. The spiked roller 2 rotates around one end of the support arm 8. When rotating away from cylinder 1, the second clamping member 302 applies an axial driving force to the cylindrical sleeve 201, causing it to move axially along the drive rod 203. This changes the relative position of the contact end face between the cylindrical sleeve 201 and cylinder 1, causing the meshing section, which was originally concentrated in the center of the cylindrical sleeve 201, to shift to one side. This allows the part that bears the greatest pressure from squeezing and friction to no longer be concentrated in a single fixed area of ​​the licker roller 2, but to alternate at different positions on the outer wall of the licker roller 2. This reduces excessive wear on the needle teeth in the middle of the licker roller 2 and improves the overall service life of the licker roller 2.

[0034] To ensure that the axial contact surfaces of the cylinder 1 and the licker-in roller 2 are fully covered during the movement and adjustment process, the axial length of the licker-in roller 2 should be greater than the axial length of the cylinder 1. This allows both ends of the licker-in roller 2 to extend beyond the ends of the cylinder 1 during axial displacement, ensuring that the needle cloth along the entire axial length of the cylinder 1 can fully contact the sharp teeth of the licker-in roller 2, thereby achieving comprehensive carding and fiber transfer.

[0035] A locking disc 202 is provided on one side wall of the cylindrical sleeve 201. The locking disc 202 is fixed to one side wall of the cylindrical sleeve 201. The drive rod 203 passes through the locking disc 202 and is slidably connected to the locking disc 202. An annular groove is formed on the circumferential surface of the locking disc 202. A connecting ring is formed at one end of the second clamping member 302. The connecting ring is embedded in the annular groove. The second clamping member 302 is rotatably connected to the cylindrical sleeve 201 through the connecting ring. Through the locking and limiting of the connecting ring and the side wall of the annular groove, the second clamping member 302 can drive the cylindrical sleeve 201 to move through the locking disc 202.

[0036] like Figure 5 , 6As shown, the stroke adjustment mechanism 3 also includes an adjustment assembly that applies axial adjustment driving force to the licker roller 2 via the second clamping member 302. The adjustment assembly includes a first clamping member 301 located on the side of the second clamping member 302 away from the licker roller 2. Both the first clamping member 301 and the second clamping member 302 are rectangular frame structures. An adjustment rod 305 with external threads on its outer wall is provided between the two side walls of the first clamping member 301. One end of the adjustment rod 305 is rotatably connected to one side wall of the first clamping member 301. One end of the first clamping member 301 has a through hole on the other side wall. The second clamping member 302 has a through hole on the side wall away from the licker roller 2. The through hole has an internal thread that matches the external thread of the adjusting rod 305. The second clamping member 302 is slidably connected to the first clamping member 301 through the extended protrusions on the upper and lower sides of the side wall. The upper and lower side walls of the first clamping member 301 are provided with linear protrusions to prevent the second clamping member 302 from deflecting during movement.

[0037] When the adjusting rod 305 rotates, the second clamping member 302 is threadedly connected to the adjusting rod 305, and the sliding fit between the second clamping member 302 and the first clamping member 301 restricts its rotation. Therefore, the second clamping member 302 will move along the axial direction of the adjusting rod 305. This movement allows the second clamping member 302 to stably and accurately drive the cylindrical sleeve 201 of the licker roller 2 to move axially along the driving rod 203.

[0038] One end of the adjusting rod 305 is connected to a drive gear 306. The convex tooth of the drive gear 306 meshes with an arc-shaped toothed plate 312. The arc-shaped toothed plate 312 is fixedly connected to the side wall of the carding device body 6. The center of the arc-shaped toothed plate 312 coincides with the center of the licker-in roller 2 when it rotates around the support swing arm 8. The driving gear 306 drives the adjusting rod 305 to rotate by rolling along the surface of the arc-shaped toothed plate 312, thereby causing the second clamping member 302, which is threadedly connected to the adjusting rod 305, to move axially along the adjusting rod 305. When the licker-in roller 2 is away from the cylinder 1, the driving gear 306 rotates counterclockwise relative to the adjusting rod 305. However, when the licker-in roller 2 is close to the cylinder 1, in order to avoid the driving gear 306 driving the adjusting rod 305 to reverse and causing the second clamping member 302 to move in the opposite direction and reset, a mechanical mechanism is provided in the driving gear 306 to realize the unidirectional rotation of the adjusting rod 305.

[0039] like Figure 7-9As shown, the drive gear 306 passes through a through hole at the shaft center and is mounted on one end of the adjusting rod 305. A ratchet 307 is fixedly connected to the adjusting rod 305 at the shaft center of the drive gear 306. An elastic pawl 310 is provided on the drive gear 306 facing the shaft center of the ratchet 307 to engage with the ratchet teeth of the ratchet 307. The elastic pawl 310 consists of a wedge-shaped end and a spring. The drive gear 306 has a mounting groove along the radial direction. The wedge-shaped end and the spring are located in the mounting groove. The two ends of the spring abut against the wedge-shaped end and the top wall of the mounting groove, respectively. The two sides of the wedge-shaped end are slidably connected to the limiting protrusions on the two side walls of the mounting groove, thereby ensuring that it maintains a linear motion trajectory after being pushed by the ratchet 307.

[0040] Through the cooperation of ratchet 307 and elastic pawl 310, when the spiked roller 2 is moving away from cylinder 1, the drive gear 306 rotates counterclockwise relative to the adjusting rod 305. The adjusting rod 305 will rotate synchronously under the push of the elastic pawl 310, thereby driving the second clamping member 302 to move axially along the adjusting rod 305, causing the cylindrical sleeve 201 of the spiked roller 2 to undergo axial displacement. When the spiked roller 2 is moving towards cylinder 1, the drive gear 306 rotates clockwise relative to the adjusting rod 305. The elastic pawl 310 will slide on the ratchet teeth of the ratchet 307, so the adjusting rod 305 will not rotate accordingly, and the second clamping member 302 will not move in the opposite direction, ensuring the unidirectionality and stability of the axial displacement of the spiked roller 2.

[0041] An adjusting rod 305 is fixedly connected to a partition block 309 on one side of the drive gear 306, and a limiting seat 308 is fixed on the other side. The end face of the partition block 309 away from the adjusting rod 305 has a groove or a fixed limiting protrusion. Through the groove or limiting protrusion on the partition block 309, the operator can use a suitable tool to manually adjust the adjusting rod 305. The drive gear 306 is rotatably connected to the annular flange of the limiting seat 308 through a limiting groove 311 opened on its side wall. The partition block 309 can prevent the drive gear 306 from axially moving on the adjusting rod 305, and the limiting seat 308 provides stable rotational support for the drive gear 306, ensuring that the drive gear 306 can rotate smoothly around the adjusting rod 305 during the return stroke.

[0042] Two arc-shaped grooves 313 are provided on the side wall of the carding device body 6. The upper and lower side walls of the first clamping member 301 extend and pass through the arc-shaped grooves 313 respectively. A straight handle is fixed between the two side walls of the first clamping member 301 extending out of the arc-shaped grooves 313. The first clamping member 301 is located at both ends of the straight handle and is connected to the side wall of the carding device body 6 by fasteners. The fasteners can be bolts or limit pins. After the stroke adjustment mechanism 3 is adjusted and the licker-in roller 2 returns to close to the cylinder 1, it can be directly connected and fixed to the side wall of the carding device body 6 by fasteners, thereby ensuring the relative position stability of the stroke adjustment mechanism 3 and the carding device body 6. An adjustment hole 315 is also provided. The adjustment hole 315 is located at the end of the stroke of the arc groove 313 and is used to change the rotation direction of the adjustment rod 305. When the cylindrical sleeve 201 on the spiked roller 2 moves from one end of the drive rod 203 to the other end, the operator can use his hand or a tool to move the wedge end on the elastic pawl 310 to disengage it from the ratchet 307. Then, the operator can use the other hand to operate the corresponding tool to manually rotate the adjustment rod 305 through the adjustment hole 315. The reverse rotation of the adjustment rod 305 pushes the second clamping member 302 to move in the opposite direction, so that the cylindrical sleeve 201 is pushed in the opposite direction by the second clamping member 302 to return to the initial position and prepare for the next stroke adjustment.

[0043] Working principle: When the operator needs to adjust the relative position of the spiked roller 2 and the cylinder 1, firstly, pull open the fasteners at both ends of the handle located on one side of the first clamping member 301. Then, the first clamping member 301 is moved along the arc-shaped groove 313 by the handle, thereby causing the spiked roller 2 to swing around the connecting fulcrum at the bottom of the support arm 8, so that the spiked roller 2 moves away from the cylinder 1. During the process of the spiked roller 2 moving away from the cylinder 1, the drive gear 306 rolls along the surface of the arc-shaped toothed plate 312. Due to the cooperation of the ratchet 307 and the elastic pawl 310, the adjusting rod... 305 will rotate synchronously. When the adjusting rod 305 rotates, the second clamping member 302, which is threadedly connected to the adjusting rod 305, will move axially along the adjusting rod 305. The second clamping member 302 drives the cylindrical sleeve 201 to move axially along the driving rod 203 through the engaging disc 202, changing the relative position of the contact end face between the cylindrical sleeve 201 and the cylinder 1. This causes the meshing section, which was originally concentrated in the center of the cylindrical sleeve 201, to shift to one side. When the piercing roller 2 moves to the appropriate position, the operator pulls the straight rod handle in the opposite direction, causing the piercing roller 2 to move to the appropriate position. The support arm 8 rotates back to a position close to the cylinder 1. During the return stroke, the drive gear 306 rotates clockwise relative to the adjusting rod 305. The elastic pawl 310 slides on the ratchet teeth of the ratchet 307, and the adjusting rod 305 does not rotate accordingly, ensuring that the second clamping member 302 does not move in the opposite direction. When the cylindrical sleeve 201 on the spiked roller 2 moves from one end of the drive rod 203 to the other end, the operator can use their hand or a tool to move the wedge-shaped end on the elastic pawl 310 to disengage it from the ratchet 307. Then, the operator can use their other hand to operate the machine. Using the corresponding tool, the adjusting rod 305 is manually rotated through the adjusting hole 315. The adjusting rod 305 rotates in the opposite direction, pushing the second clamping member 302 to move in the opposite direction. This causes the cylindrical sleeve 201 to move in the opposite direction under the push of the second clamping member 302, so as to return to the initial position and prepare for the next stroke adjustment. This cycle is repeated. By continuously changing the contact position between the licker-in roller 2 and the cylinder 1, the excessive wear of the needle teeth in the middle of the licker-in roller 2 is reduced, the overall service life of the licker-in roller 2 is improved, and the efficient and stable operation of the carding device is ensured at the same time.
