Description

Technical Field

[0001] The utility model relates to the technical field of carding machines, in particular to a carding machine barrel changing component. Background Art

[0002] Carding machines are used to open and comb cotton laps, remove impurities, and gather them into slivers (also known as slivers), which are then stored in cotton cans. Since the slivers produced by the carding machine are continuous threads, the cotton cans need to be frequently replaced during storage.

[0003] When storing tampons, the cotton drum needs to rotate to store the tampons in an orderly manner, so that the internal space of the cotton drum can be fully utilized and the storage rate of the cotton drum can be improved. Some existing cotton drums use the friction between the roller and the outside of the cotton drum to drive the roller to rotate. However, as the wear of the roller and the outside of the cotton drum increases, the friction between the two will become smaller and smaller until it is difficult to drive the cotton drum to rotate. The service life is relatively short and the cost of consumables is relatively high. Utility Model Content

[0004] In view of this, the purpose of the present invention is to propose a cotton carding machine barrel changing assembly to solve the problem that the friction between the roller and the cotton barrel is reduced, thereby affecting the cotton sliver storage efficiency.

[0005] Based on the above purpose, the utility model provides a carding machine barrel changing assembly, comprising a bottom bracket and a revolution disk rotatably arranged on the bottom bracket, and a revolution drive unit for driving the revolution disk to rotate. The carding machine barrel changing assembly also includes:

[0006] A plurality of grooves are provided on the revolution disk.

[0007] A rotating disc arranged in the groove is rotated, and a spline groove is provided on the top of the rotating disc. The spline groove is used for circumferentially fixing the spline block at the bottom of the cotton cylinder.

[0008] A rotation driving unit is used to drive one of the rotating disks to rotate.

[0009] Preferably, the carding machine barrel changing assembly further comprises:

[0010] An outer bracket is fixed on the bottom bracket.

[0011] A lifting frame is vertically slidably sleeved on the outer bracket.

[0012] A lifting member is used to drive the lifting frame to move up and down.

[0013] A strip-threading bucket is fixedly arranged on the top of the lifting frame.

[0014] A guide frame is fixed on the top of the outer bracket, and is used for supporting and guiding the wool strips into the strip feeding bucket.

[0015] Preferably, the cotton carding machine tube changing assembly also includes a sliver feeding part provided on the lifting frame. When the cotton tube is replaced, the sliver feeding part is used to clamp and fix the broken ends of the cotton slivers, and after the cotton tube is replaced, the cotton slivers accumulated between the guide frame and the sliver feeding part are accelerated to be discharged into the replaced cotton tube.

[0016] Preferably, the strip feeding part includes a support frame fixed to the top of the lifting frame, two conveying rollers arranged on the support frame for relative rotation, and a driving member for driving the two conveying rollers to rotate in opposite directions.

[0017] Preferably, the carding machine tube changing assembly further comprises a pair of scissors provided on the support frame, and the scissors are used to cut the cotton strips before the cotton tube is replaced.

[0018] Preferably, the scissors are located between the conveying roller and the strip threading bucket.

[0019] Preferably, the gap between the two conveying rollers and the symmetry axis of the scissors are both located on the axis of the strip feeding bucket, and the cotton strips pass through the guide frame and between the two conveying rollers in sequence, and then pass downward between the blades of the scissors and the inside of the strip feeding bucket in sequence.

[0020] Preferably, the rotation drive unit and the strip-threading bucket are located on the same radial line of the revolution disk.

[0021] The beneficial effects of the utility model are as follows: the utility model evenly arranges a plurality of self-rotating discs on the top of the revolution disc, and the cotton tube under the strip feeding bucket can be replaced by revolution, and the spline block at the bottom of the cotton tube is matched with the spline groove on the self-rotating disc, and the circumferential speed difference when the self-rotating disc rotates is utilized to automatically calibrate the position of the spline block and the spline groove and insert the spline block into the spline groove, so as to realize circumferential self-fixation of the cotton tube. The operation is simple and efficient, and the interval time of cotton tube replacement can be shortened, thereby improving the cotton tube replacement efficiency. When the cotton tube is replaced, the end of the cotton tube can be fixed by the clamping effect of the conveying roller on the cotton strip, and after the cotton tube is replaced, the running speed of the conveying roller can be controlled to accelerate the discharge of the cotton strip until all the cotton strips accumulated between the guide frame and the conveying roller are discharged into the cotton tube, and then the rotation speed of the conveying roller is adjusted down to make the discharge speed of the cotton carding machine and the discharge speed of the conveying roller consistent, thereby avoiding the excessive lowering of the cotton strip when the cotton tube is replaced and difficulty in falling into the replaced cotton tube, thereby improving the connection effect of cotton tube replacement.

[0030] like Figures 1 to 3As shown, a carding machine can change assembly includes a bottom bracket 1 and a revolution disk 2 rotatably mounted on the bottom bracket 1, a revolution drive unit 3 for driving the revolution disk 2 to rotate, the revolution drive unit 3 includes a gear ring fixedly mounted on the outside of the revolution disk 2 and a spur gear rotatably mounted on the outside of the bottom bracket 1, a first drive motor for driving the spur gear to rotate, and the spur gear is meshed with the gear ring. The carding machine can change assembly also includes:

[0031] A plurality of grooves 4 are provided on the revolution plate 2 .

[0032] The rotating disc 5 is rotated in the groove 4. A spline groove 6 is provided on the top of the rotating disc 5. The spline groove 6 is used to circumferentially fix the spline block at the bottom of the cotton cylinder. The rotating connection between the revolving disc 2 and the rotating disc 5 is located at the center of the bottom of the two.

[0033] The rotation driving part 7 is used to drive one of the rotating disks 5 to rotate. The rotation driving part 7 includes a transmission gear that rotates between the revolution disk 2 and the bottom bracket 1. The top of the bottom bracket 1 is provided with an annular groove. The bottom end of the shaft rod at the bottom of the rotating disk 5 passes through the bottom of the revolution disk 2 and extends into the annular groove, and the bottom end of the shaft rod at the bottom of the rotating disk 5 is fixed with a sub-gear. The external rotation of the bottom bracket 1 is provided with a main gear, and a second drive motor is used to drive the main gear to rotate. The two sides of the transmission gear are respectively engaged with the main gear and the sub-gear, and the transmission gear is located at the tangent point of the circular path of the sub-gear revolution. In this way, when the revolution disk 2 drives the rotating disk 5 and the sub-gear to revolve, the sub-gear can be replaced in sequence to engage with the transmission gear.

[0034] like Figure 1 and Figure 3 As shown, the carding machine can changing assembly also includes:

[0035] An outer bracket 8 is fixed to the bottom bracket 1 .

[0036] A lifting frame 10 is vertically slidably sleeved on the outer bracket 8.

[0037] The lifting member 11 is used to drive the lifting frame 10 to move up and down. The lifting member 11 includes a vertically rotating screw arranged outside the outer bracket 8, and a third drive motor for driving the screw to rotate. The bottom end of the lifting frame 10 is threadedly sleeved on the screw, and the overall shape of the lifting frame 10 is Z-shaped.

[0038] A strip-threading bucket 12 is fixedly arranged on the horizontal surface of the top of the lifting frame 10 , and the strip-threading bucket 12 corresponds to the rotating disk 5 .

[0039] A guide frame 9 is fixed to the top of the outer bracket 8 , and the top of the guide frame 9 is a circular ring. The guide frame 9 is used to support and guide the wool strips into the strip feeding bucket 12 .

[0040] The carding machine tube changing assembly also includes a sliver feeding part 13 provided on the lifting frame 10. When the cotton tube is replaced, the sliver feeding part 13 is used to clamp and fix the broken ends of the cotton slivers. At the same time, the carding machine continues to operate, and excess cotton slivers will accumulate between the guide frame 9 and the sliver feeding part 13 to prevent the broken ends of the cotton slivers from falling too long and being difficult to fall into the replaced cotton tube. After the cotton tube is replaced, the cotton slivers accumulated between the guide frame 9 and the sliver feeding part 13 are accelerated to be discharged into the replaced cotton tube.

[0041] like Figure 3 As shown, the strip feeding section 13 includes a support frame 131 fixed to the top of the lifting frame 10 and two conveying rollers 132 arranged on the support frame 131 for relative rotation, and a driving member 133 for driving the two conveying rollers 132 to rotate in opposite directions. The driving member 133 includes a vertical gear fixed to one end of the conveying roller 132, which is used to drive a servo motor to rotate one of the conveying rollers 132, and the two vertical gears are engaged with each other.

[0042] The carding machine tube changing assembly further comprises a pair of scissors 14 provided on the support frame 131 , and the scissors 14 are used to cut the cotton strips before the cotton tube is replaced.

[0043] The scissors 14 are located between the conveying rollers 132 and the strip threading bucket 12 .

[0044] Before the cotton tube is replaced, the scissors can be controlled to cut the cotton strips shorter, so that the broken ends of the cotton strips can be located at the bottom between the two conveying rollers 132, so that the two conveying rollers 132 can clamp and fix the broken ends of the cotton strips, and the carding machine continues to operate when the cotton tube is replaced. The excess cotton strips will accumulate between the guide frame 9 and the top between the two conveying rollers 132. After the cotton tube is replaced, it is started.

[0045] like Figures 1 to 3 As shown, the gap between the two conveying rollers 132 and the symmetry axis of the scissors 14 are both located on the axis of the strip feeding bucket 12, and the cotton strips pass through the guide frame 9 and between the two conveying rollers 132 in sequence, and then pass downward between the blades of the scissors 14 and the interior of the strip feeding bucket 12 in sequence.

[0046] The rotation driving part 7 and the strip-threading bucket 12 are located on the same radial line of the revolution disk 2 .

[0047] Such a design can smoothly convey the cotton strips into the cotton tube, and the rotational speed of the conveying roller 132 can be changed by controlling the driving member 133, so that the conveying speed of the conveying roller 132 for the cotton strips is close to the speed at which the cotton carding machine outputs the cotton strips. In this way, a certain tension can be maintained during the conveying of the cotton strips, avoiding the problem of cotton strips being retained or broken, and the cotton strips accumulated during the replacement of the cotton tube can be accelerated to be conveyed into the empty cotton tube after replacement. After the accumulated cotton strips are conveyed, the driving member 133 is controlled to drive the rotational speed of the conveying roller 132 to return to normal, thereby improving the smoothness of the cotton tube replacement connection during the cotton strip unloading process.

[0048] Working principle: The cotton sliver is output from the output end of the carding machine. After that, the cotton sliver passes through the ring at the top of the guide frame 9 and crosses between the two conveyor rollers 132. From the top between the two conveyor rollers 132, it passes through the gap between the two conveyor rollers 132 from top to bottom, and continues to pass through the blade of the scissors 14 and the inside of the strip feeding bucket 12 vertically downward in turn, and finally falls into the cotton tube located below the strip feeding bucket 12. After the cotton tube is filled with cotton slivers, the drive member 133 is stopped, so that the two conveyor rollers 132 are stationary and the cotton slivers are clamped between them, and then the scissors 14 are controlled to cut the cotton slivers. The revolution drive unit 3 is then controlled to drive the revolution disk 2 to rotate a certain angle. After the revolution disk 2 drives the self-rotating disk 5 and the cotton tube on the self-rotating disk 5 to revolve to the bottom of the strip feeding bucket 12, the revolution drive unit 3 is stopped and the self-rotating drive unit 7 is started to drive the self-rotating disk 5 to rotate. During this period, since the carding machine continues to operate, the lifting member 11 is started to drive the lifting frame 10 to rise, so that the length of the cotton strip hanging is increased, which can keep a certain tension on the cotton strip between the carding machine and the guide frame 9, so that the cotton strip can continue to move toward the guide frame 9 and the conveying roller 1 32, after the cotton tube is replaced, the driving member 133 is started to operate at high power to accelerate the driving roller 132 to rotate, so as to accelerate the unloading speed of the cotton strips. After the accumulated cotton strips are transported, the driving member 133 is controlled to resume normal operation again, and the speed of the conveying roller 132 is restored to a speed close to the speed of the carding machine outputting the cotton strips. At this time, the lifting member 11 can be controlled to drive the lifting frame 10 to descend to the initial height, and the cotton strips can be continued to be unloaded. After the empty cotton tube is placed on the top of the rotary disk 5, it is revolved. After the disk 2 drives the rotating disk 5 and the cotton tube to revolve to the cotton strip unloading position, the revolving drive unit 3 is stopped and the rotating drive unit 7 is started to drive the rotating disk 5 to rotate. When the centrifugal force of the rotating disk 5 during rotation is greater than the friction between the cotton tube and the rotating disk 5, relative rotation is formed between the two, so that the spline block at the bottom of the cotton tube and the spline groove 6 at the top of the rotating disk can be automatically calibrated, and the spline block falls into the spline groove 6, realizing the constraint of the circumferential freedom of the cotton tube, so that the cotton tube can rotate synchronously with the rotating disk 5, thereby improving the stability of the cotton tube when storing cotton strips.
