Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a hemp strip conveying device for a combing machine. Background Technology

[0002] Combing machines are widely used in the textile industry. In the production of hemp sliver, the hemp sliver is first clamped by a hemp clamper. After clamping, the hemp clamper is conveyed, then locked, and then transported to the next process to complete the clamping and combing of the hemp sliver. However, the existing hemp sliver conveying mechanism is composed of various independent devices, which operate independently and each is responsible for completing each action independently. This results in a large overall size of the equipment, which occupies a lot of space, has a complex overall structure, and leads to a long equipment assembly and debugging cycle, as well as high maintenance costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing hemp strip conveying mechanism is composed of various independent devices, which operate independently, resulting in a large overall size of the equipment, which in turn occupies a lot of space, has a complex overall structure, and leads to a long equipment assembly and debugging cycle and high maintenance costs, a hemp strip conveying device for combing machine is provided.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a combing machine hemp strip conveying device, comprising: a conveying mechanism for conveying hemp strips;

[0005] A locking mechanism, which is installed on the conveying mechanism, is used to lock the hemp clamp;

[0006] The carding mechanism, which is mounted on the conveying mechanism, is used for carding hemp strips;

[0007] The system also includes a linkage mechanism mounted on the conveying mechanism. This mechanism connects the conveying, locking, and combing mechanisms, controlling their sequential operation to lock the hemp clamps, comb the hemp strips on them, and convey the hemp clamps. Compared to existing technologies, this solution uses a linkage mechanism to sequentially drive the conveying, locking, and combing mechanisms, achieving the locking, combing, and conveying of the hemp clamps. This significantly reduces the equipment's size, simplifies the overall structure, facilitates maintenance, and shortens assembly and speed adjustment cycles.

[0008] In some preferred embodiments, the linkage mechanism includes a rotating shaft rotatably mounted on the conveying mechanism, a first cam mechanism mounted on the rotating shaft and drivenly connected to a locking mechanism, a second cam mechanism mounted on the rotating shaft and drivenly connected to a combing mechanism, and a third cam mechanism mounted on the rotating shaft and drivenly connected to the conveying mechanism.

[0009] In some preferred embodiments, the locking mechanism includes a locking shaft for locking or loosening the nut on the hemp clamp. The locking shaft is rotatably mounted on a conveying mechanism. The conveying mechanism is provided with a drive mechanism for driving the locking shaft to rotate. A lifting mechanism is provided between the locking shaft and a first cam mechanism. The first cam mechanism drives the locking shaft to move through the lifting mechanism and controls the locking shaft to be in or out of its predetermined position, thereby realizing the operation of the nut on the hemp clamp.

[0010] In some preferred embodiments, the lifting mechanism includes a lifting rod, which is rotatably mounted on the conveying mechanism. One end of the lifting rod is mounted on a locking shaft, and the other end of the lifting rod is connected to a first cam mechanism for transmission.

[0011] In some preferred embodiments, the locking mechanism further includes a reversing mechanism, which is disposed between the driving mechanism and the locking shaft. The reversing mechanism is connected to the first cam mechanism and is used to switch the locking shaft to rotate forward or backward, so as to loosen and then tighten the nut on the hemp clamp first.

[0012] In some preferred embodiments, the reversing mechanism includes a first bevel gear, a second bevel gear, a third bevel gear, and a reversing gear. The first, second, and third bevel gears are all rotatably mounted on the conveying mechanism. The first bevel gear meshes with the second and third bevel gears respectively. The first bevel gear is connected to the drive mechanism and is located between the second and third bevel gears. The second and third bevel gears are arranged opposite each other and their rotation center axes coincide. The reversing gear is connected to the locking shaft by a profile. The reversing gear is located between the second and third bevel gears. The second and third bevel gears are provided with meshing teeth matching the reversing gear on the side near the reversing gear. The reversing gear is connected to the first cam mechanism and is used to control the meshing of the reversing gear with the meshing teeth of the first or second bevel gear, so as to realize the forward or reverse rotation of the locking shaft driven by the reversing gear.

[0013] In some preferred embodiments, the combing mechanism includes a first clamping plate and a second clamping plate rotatably mounted on the conveying mechanism. The first clamping plate and the second clamping plate are arranged opposite to each other. The first clamping plate is connected to the second cam mechanism for mutual transmission, thereby driving the first clamping plate to move closer to or away from the second clamping plate. The first clamping plate and the second clamping plate are controlled to clamp the hemp strip and rotate with the first clamping plate to comb the hemp strip. Alternatively, after combing, the first clamping plate and the second clamping plate are controlled to release the hemp strip.

[0014] In some preferred embodiments, the conveying mechanism includes a frame, a slide rail mounted on the frame for placing the hemp clamp, and a shift fork mechanism for displacing the hemp clamp. The shift fork mechanism is connected to a third cam mechanism and is used to drive the lever to slide back and forth on the frame, thereby enabling the shift fork mechanism to drive the hemp clamp to move along the conveying direction on the slide rail.

[0015] In some preferred embodiments, the slide rail is hinged with a plurality of stop teeth, which prevent the clamping device from retracting.

[0016] The beneficial effects of this invention are as follows: When the combing machine hemp strip conveying device of this invention is in use, the conveying mechanism, locking mechanism and combing mechanism are driven in sequence by the linkage mechanism to realize the locking of the hemp clamp, the combing of the hemp strips on the hemp clamp and the conveying of the hemp clamp. This greatly reduces the size of the equipment, the overall equipment structure is simple, it is easy to maintain later, and the equipment assembly and speed adjustment cycle is shortened. It avoids the problems of existing combing machines which are composed of various mechanisms, each of which operates independently, resulting in a large overall size, large space occupation, complex overall structure, long equipment assembly and debugging cycle and high maintenance costs.

[0033] like Figure 1-7 As shown, a combing machine hemp strip conveying device includes a locking mechanism 2, a combing mechanism 3, a conveying mechanism 1, and a linkage mechanism 4. The locking mechanism 2 is mounted on the frame 101 and is used to lock the hemp clamps. The combing mechanism 3 is mounted on the frame 101 and is used to comb the hemp strips. The conveying mechanism 1 is mounted on the frame 101 and is used to convey the hemp clamps. The linkage mechanism 4 is mounted on the frame 101 and is used to drive the conveying mechanism 1, the locking mechanism 2, and the combing mechanism 3 to each other, controlling the locking mechanism 2, the combing mechanism 3, and the conveying mechanism 1 to operate sequentially, thereby realizing the locking of the hemp clamps, the combing of the hemp strips on the hemp clamps, and the conveying of the hemp clamps.

[0034] The linkage mechanism 4 includes a rotating shaft 401 rotatably mounted on the frame 101. The rotating shaft 401 is connected to an external power mechanism and drives the rotating shaft 401 to rotate. A first cam mechanism 402 is mounted on the rotating shaft 401 and is connected to the locking mechanism 2. A second cam mechanism 403 is mounted on the rotating shaft 401 and is connected to the combing mechanism 3. A third cam mechanism 404 is mounted on the rotating shaft 401 and is connected to the conveying mechanism 1.

[0035] The locking mechanism 2 includes a locking shaft 201, which is used to lock or loosen the nut on the hemp clamp. The locking shaft 201 is rotatably mounted on the frame 101. The frame 101 is provided with a drive mechanism for driving the locking shaft 201 to rotate. A lifting mechanism is provided between the locking shaft 201 and the first cam mechanism 402. The first cam mechanism 402 drives the locking shaft 201 to move up and down through the lifting mechanism and controls the locking shaft 201 to be in or out of its predetermined position, thereby realizing the operation of the nut on the hemp clamp.

[0036] The lifting mechanism includes a lifting rod 202, which is rotatably mounted on the frame 101. One end of the lifting rod 202 is provided with a slot. A locking shaft 201 is provided with a flange and is located inside the slot of the lifting rod 202. The flange is located above the slot. The first cam mechanism 402 includes a first inner cam, which is fixedly connected to the rotating shaft 401. The first inner cam and the lifting rod 202 are connected by a first linkage mechanism, so that the other end of the lifting rod 202 is connected to the first cam mechanism 402.

[0037] The locking mechanism 2 also includes a reversing mechanism 203, which is located between the drive mechanism and the locking shaft 201. The reversing mechanism 203 is connected to the first cam mechanism 402 and is used to switch the locking shaft 201 to rotate forward or backward, so as to loosen and then tighten the nut on the clamping device.

[0038] The reversing mechanism 203 includes a first bevel gear 2031, a second bevel gear 2032, a third bevel gear 2033, and a reversing gear 2034. The first bevel gear 2031, second bevel gear 2032, and third bevel gear 2033 are all rotatably mounted on the frame 101. The first bevel gear 2031 meshes with the second bevel gear 2032 and the third bevel gear 2033 respectively. The first bevel gear 2031 is connected to the drive mechanism and is located between the second bevel gear 2032 and the third bevel gear 2033. The second bevel gear 2032 and the third bevel gear 2033 are arranged opposite to each other, and their rotation axes coincide. The reversing gear 2034... 4. The locking shaft 201 is connected by a profile. The reversing gear 2034 is located between the second bevel gear 2032 and the third bevel gear 2033. The second bevel gear 2032 and the third bevel gear 2033 are provided with meshing teeth that match the reversing gear 2034 on the side near the reversing gear 2034. The first cam mechanism 402 also includes a second inner cam. The second inner cam is fixedly installed on the rotating shaft 401. The reversing gear 2034 is connected to the second inner cam of the first cam mechanism 402 through the second linkage mechanism. The reversing gear 2034 is controlled to mesh with the meshing teeth of the first bevel gear 2031 or the meshing teeth of the second bevel gear 2032, so that the reversing gear 2034 drives the locking shaft 201 to rotate forward or backward.

[0039] The combing mechanism 3 includes a first clamping plate 301 and a second clamping plate 302 respectively rotatably mounted on the frame 101. The first clamping plate 301 and the second clamping plate 302 are arranged opposite to each other. The second cam mechanism 403 includes an outer cam, which is fixedly mounted on the rotating shaft 401. The first clamping plate 301 is connected to the outer cam of the second cam mechanism 403 through a third linkage mechanism, thereby driving the first clamping plate 301 to move closer to or away from the second clamping plate 302. The second cam mechanism 403 controls the clamping of the hemp strip by the first clamping plate 301 and the second clamping plate 302 and drives the second clamping plate 302 to rotate with the first clamping plate 301 to comb the hemp strip. Alternatively, after combing, it controls the first clamping plate 301 and the second clamping plate 302 to release the hemp strip. In this embodiment, the second clamping plate 302 can be automatically reset by a coil spring or by setting a counterweight on the second clamping plate 302.

[0040] The conveying mechanism 1 includes a slide rail 102 and a shifting fork mechanism for displacing the hemp clamp. The slide rail 102 is mounted on the frame 101 and is used to hold the hemp clamp. Several stop teeth 105 are hinged on the slide rail 102 to prevent the hemp clamp from retracting. A shifting lever 103 is slidably mounted on the frame 101. The shifting fork mechanism includes a shifting lever 103 and shifting teeth 104. The shifting lever 103 is slidably mounted on the frame 101 and is parallel to the slide rail 102. The shifting teeth 104 are hinged to the shifting lever 103. The shifting lever 103 is connected to a fourth linkage mechanism. The third inner cam of the third cam mechanism 404 is connected to the third cam mechanism and is used to drive the lever 103 to slide back and forth on the frame 101, so that the lever 104 drives the hemp clamp to move along the conveying direction on the slide rail 102. This is one implementation of the lever mechanism. The specific structure is similar to the published Chinese utility model patent, which has the application number CN201821672155.X, the patent name is hemp combing machine lever mechanism, and the application date is 20181015. That is, the lever mechanism conveys the hemp clamp from one end to the other in a step-by-step manner.

[0041] When the above-mentioned combing machine hemp strip conveying device is in use, the external power mechanism drives the rotating shaft 401 of the linkage mechanism 4 to rotate. The rotating shaft 401 drives the first cam mechanism 402, the second cam mechanism 403 and the third cam mechanism 404. The first cam mechanism 402 drives the locking mechanism 2 to move, the second cam mechanism 403 drives the combing mechanism 3 to move, and the third cam drives the conveying mechanism 1 to move.

[0042] First, the rotating shaft 401 drives the first inner cam of the first cam mechanism 402 to rotate. At this time, the nut of the hemp clamp corresponds to the locking shaft 201. The rotation of the first inner cam drives the lifting rod 202 to move down through the first linkage mechanism. The locking shaft 201 moves down under its own weight and enters its working position. At this time, the locking shaft 201 and the nut cooperate with each other. The driving mechanism is a servo motor, which drives the first bevel gear 2031 to rotate. The first bevel gear 2031 drives the second bevel gear 2032 and the third bevel gear 2033 to rotate respectively. At this time, the second linkage mechanism of the first cam mechanism 402 drives the reversing mechanism 203. The reversing gear 2034 engages with the meshing teeth of the second bevel gear 2032, the locking shaft 201 reverses and loosens the nut, thus loosening the hemp clamp. As the second internal gear rotates, it controls the second linkage mechanism to drive the reversing gear 2034 to engage with the meshing teeth of the third bevel gear 2033, the locking shaft 201 rotates forward and tightens the nut, thus clamping the hemp strip onto the hemp clamp. As the first internal cam rotates, it controls the lifting rod 202 of the lifting mechanism to move upward. The lifting rod 202 abuts against the flange and drives the locking shaft 201 to move upward, thus disengaging the locking shaft 201 from its position, completing the process of first loosening and then tightening the hemp clamp.

[0043] Secondly, the rotating shaft 401 drives the outer cam of the second cam mechanism 403 to drive the first clamping plate 301 to rotate on the frame 101 through the third linkage mechanism. The first clamping plate 301 rotates towards the second clamping plate 302 and clamps the hemp strip. Then, the first clamping plate 301 drives the second clamping plate 302 to rotate together and comb the hemp strip. As the outer cam of the second cam mechanism 403 rotates, it drives the first clamping plate 301 to rotate away from the second clamping plate 302 until the hemp strip is released, thus completing the combing of the hemp strip.

[0044] Finally, the rotating shaft 401 drives the third cam mechanism 404. The third inner cam of the third cam mechanism 404 drives the lever 103 of the shift fork mechanism to reciprocate linearly on the frame 101 through the fourth linkage mechanism, and causes the shift tooth 104 to drive the hemp clamp to be transported from one end to the other on the slide rail 102, thus completing the transport of the hemp clamp.

[0045] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
