Description

Technical Field

[0001] The utility model belongs to the technical field of cotton strip feeding of a drawing frame, and more specifically relates to an auxiliary feeding device for a drawing frame guide elevated frame. Background Art

[0002] The draw frame is an important mechanical equipment in the textile process. It is mainly used to improve and process the slivers produced by the previous process (such as roving or carding), and to combine, draft and twist multiple rovings or slivers into slivers of better quality. The feeding of the draw frame refers to correctly and evenly feeding the prepared raw materials (usually the slivers output by the previous process) into the draw frame. The feeding part of the draw frame is usually designed with a guide frame to guide the slivers accurately into the machine.

[0003] At present, the cotton strips drawn out from the cotton strip can are guided into the draw frame after passing through the sliver guide rack, but there is no feeding facility on the sliver guide rack. The cotton strips are only fed through the draw frame. It is relatively laborious to bring the cotton strips on the sliver guide rack into the draw frame, and the cotton strips passing through the sliver guide rack are not stable enough, and are prone to deviation and entanglement. The cotton strip feeding effect is not good, and the efficiency of the cotton strip feeding of the draw frame is low, which greatly affects the quality of subsequent spinning.

[0004] Therefore, it is necessary to provide an auxiliary feeding device for the drawing frame guide bar elevated frame to solve the above technical problems. Utility Model Content

[0016] A pull plate is arranged at the end of the limiting rod, and a first elastic member is arranged between the pull plate and the bracket.

[0017] Furthermore, a connecting rod is provided on each of the two arc-shaped positioning plates, and an extrusion column is provided at one end of the connecting rod away from the arc-shaped positioning plate.

[0018] Furthermore, a fixed sleeve is provided on the arc-shaped positioning plate, a slide groove is provided in the fixed sleeve, the connecting rod is slidably connected in the slide groove, and a second elastic member is provided between one end of the connecting rod away from the extrusion column and the inner wall of the slide groove.

[0020] Furthermore, the outer wall of the feeding cylinder is provided with a plurality of grooves.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this scheme, the slivers will pass through the upper side of the feeding cylinder and then be fed into the drawing frame. At the same time, the driving mechanism will drive the feeding cylinder to rotate along the feeding direction of the slivers, so that the feeding cylinder can not only support and lift the slivers, but also play a further active feeding role for the slivers through the rotating feeding cylinder, which can assist in supporting and feeding the slivers, avoid the collapse of the slivers on the guide frame, and enable the slivers to be fed more actively and stably, making the sliver feeding more time-saving and labor-saving, greatly improving the efficiency of sliver feeding in the drawing frame.

[0023] 2. In this scheme, the positioning component can improve the stability of the sliver feeding process, which can greatly avoid the deviation and entanglement of the slivers during feeding, significantly improve the feeding effect of the slivers, make the feeding of the slivers smoother, the feeding efficiency is high, the sliver feeding is stable, and the quality of subsequent spinning is improved; the position of the positioning component on the feeding cylinder can also be changed, and then the position of the positioning component can be adjusted according to specific on-site needs and the feeding position of the slivers. It has strong flexibility and can meet the needs of various situations.

[0024] 3. In this solution, the two arc-shaped positioning plates can be removed and installed, and can be repaired or replaced without overall repair or replacement, which reduces the complexity of processing, saves time and effort, and can increase the service life of the device. In addition, the positioning components can be reused, which reduces production costs, has good applicability, strong flexibility, and can be widely promoted and used.

[0025] 4. In this solution, the extrusion columns on the arc-shaped positioning plates on the left and right sides of the sliver are in contact with the sliver. On the one hand, the extrusion columns can increase the friction with the sliver, and can further provide part of the force to drive the feeding of the sliver, thereby improving the efficiency and effect of the active feeding of the sliver; on the other hand, the rotational extrusion of the sliver by the extrusion columns can make the sliver smoother and more complete, thereby improving the feeding quality of the sliver.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-4 The auxiliary feeding device for the guide bar frame of the drawing machine includes a guide bar frame 1, and also includes: a feeding cylinder 2, which is rotatably arranged on the guide bar frame 1, and a driving mechanism for driving the feeding cylinder 2 to rotate is arranged on the guide bar frame 1; a positioning component 3, which is arranged on the feeding cylinder 2; the positioning component 3 includes two arc-shaped positioning plates 31, and a first set of plates 32 and a second set of plates 33 are respectively arranged on the two arc-shaped positioning plates 31, and the first set of plates 32 and the second set of plates 33 are connected by a fixing component 34, and a limiting component 35 is provided on the second set of plates 33, which is used to fix the second set of plates 33 on the feeding cylinder 2.

[0037] When in use, the device is installed on the guide bar frame 1, and then a plurality of positioning components 3 are installed on the feeding cylinder 2, two positioning components 3 form a group, and the two positioning components 3 in each group are symmetrically arranged. After that, after the cotton strips in the cotton strip drum are guided to the guide bar frame 1, the cotton strips will pass through the upper side of the feeding drum 2 and then be fed into the drawing machine, that is, the cotton strips are placed on the feeding drum 2, and at the same time, the driving mechanism will drive the feeding drum 2 to rotate, so that the feeding drum 2 rotates along the feeding direction of the cotton strips, so that the feeding drum 2 can not only support and place the cotton strips, but also play a further active feeding role on the cotton strips through the rotating feeding drum 2, that is, the feeding drum 2 will have a pushing effect on the contacted cotton strips, that is, through the friction with the cotton strips, it has a force on the cotton strips in the feeding direction, and then can assist in supporting and feeding the cotton strips, can avoid the collapse of the cotton strips on the guide bar frame 1, and can make the cotton strips be fed more actively and stably, making the cotton strip feeding more time-saving and labor-saving, greatly improving the efficiency of cotton strip feeding in the drawing machine.

[0038] When the cotton slivers pass through the feeding cylinder 2, the cotton slivers are located between the two positioning components 3 of each group, that is, the cotton slivers are located between the two arc-shaped positioning plates 31. The arc-shaped positioning plates 31 limit the position of the cotton slivers, thereby improving the smoothness of the cotton sliver feeding process, greatly avoiding the deviation and mutual entanglement of the cotton slivers during feeding, and significantly improving the feeding effect of the cotton slivers. The feeding of the cotton slivers is smoother and the feeding efficiency is high, and problems such as feeding jams are reduced. The cotton sliver feeding is stable, thereby improving the quality of subsequent spinning.

[0039] When the fixing of the second set plate 33 by the limiting assembly 35 is released, the second set plate 33, the first set plate 32 and the arc-shaped positioning plate 31 can be driven to move along the feeding tube 2, so that the position of the positioning component 3 on the feeding tube 2 can be changed, and then the position of the positioning component 3 can be adjusted according to the specific site requirements and the feeding position of the cotton strips. It has a wide range of applications and strong flexibility, and can meet the needs of various situations. After the adjustment is completed, the second set plate 33 can be fixed by the limiting assembly 35.

[0040] The outer wall of the feeding cylinder 2 is provided with a plurality of grooves 12. Through the setting of the grooves 12, when the feeding cylinder 2 is rotated to drive the feeding cylinder 2 to assist in feeding, the grooves 12 of the feeding cylinder 2 can reduce the smoothness of the surface of the feeding cylinder 2, thereby improving the driving effect of the feeding cylinder 2 and the cotton strips, so that the active feeding of the cotton strips is good.

[0041] In this embodiment, preferably, please refer to Figure 2 and Figure 4 The fixing assembly 34 includes: a first fixing plate 341 and a second fixing plate 342, which are respectively arranged on the first set plate 32 and the second set plate 33, and the first fixing plate 341 and the second fixing plate 342 are both provided with fixing holes 343; fixing bolts 344, which are arranged on the first fixing plate 341 and are threadedly connected with the fixing holes 343. Initially, the first set plate 32 and the second set plate 33 are in a separated state, such as Figure 4 As shown, when in use, the two arc-shaped positioning plates 31 are matched and sleeved on the outer wall of the feeding tube 2. At this time, the positions of the first fixing plate 341 and the second fixing plate 342 correspond to each other. After the fixing bolts 344 and the fixing holes 343 are threadedly connected, the first fixing plate 341 and the second fixing plate 342 can be fixedly connected together, that is, the two arc-shaped positioning plates 31 are fixed on the feeding tube 2. Then, the two arc-shaped positioning plates 31 can be removed and installed, and can be repaired or replaced without overall repair or replacement, which reduces the complexity of processing, saves time and effort, and can increase the service life of the device. In addition, the positioning component 3 can be reused, which reduces the production cost. The number of positioning components 3 to be installed can also be determined according to the number of cotton strips guided to the guide bar elevated frame 1. It has good applicability and strong flexibility, and can be widely promoted and used.

The first elastic member 354 in the present application adopts a spring. When the second set plate 33 is installed on the feeding tube 2 or the position of the second set plate 33 and the arc-shaped positioning plate 31 on the feeding tube 2 needs to be adjusted, the pull plate 353 can be pulled outward first, and the pull plate 353 will drive the limit rod 352 to move, and the first elastic member 354 will be stretched, and the limit rod 352 moves into the second set plate 33. After the second set plate 33 is put on the feeding tube 2 or the second set plate 33 is adjusted to the specified position, the limit rod 352 corresponds to the limit hole 4 at the corresponding position, and then the pull plate 353 is released. The limit rod 352 will be driven to move by the rebound force of the first elastic member 354, and the limit rod 352 will eventually enter the limit hole 4, so that the second set plate 33 can be fixed on the feeding tube 2, and then the position of the arc-shaped positioning plate 31 can be limited.
