Description

Technical Field

[0001] This utility model belongs to the field of textile equipment, and in particular relates to a pusher device for a carding machine. Background Technology

[0002] The carding machine is a crucial link in the spinning process, its function can be summarized as "opening, removing impurities, mixing, combing, and forming sliver," directly affecting yarn quality, output, and subsequent processing efficiency. From raw cotton to spun sliver, the performance of the carding machine (such as the sharpness of the carding cloth, rotation speed, and dust removal effect) is one of the decisive factors.

[0003] In existing technology, carding machines gather the carded fibers into continuous slivers, and coiling machines then regularly wind the slivers into cans to form neat packages. To facilitate can replacement, coiling machines are generally equipped with a pushing mechanism that pushes empty cans into the machine and pushes out the packaged sliver cans. Simultaneously, since the sliver cans need to rotate for material collection in the coiling machine, auxiliary wheels are typically added around the cans to stabilize their rotation. To coordinate with the pushing mechanism, these auxiliary wheels need to rotate upwards during pushing, and this rotation is achieved using a rotating motor or cylinder. This results in a large number of power units in the coiling machine, making operation complex. Reducing the operating cost of coiling machines is currently the direction for improvement. Utility Model Content

[0004] This invention addresses the technical problem of high operating costs of existing carding machines by proposing a pushing device for carding machines that is reasonably designed, simple in structure, easy to process, and capable of linking the pushing mechanism and auxiliary wheel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a pushing device for a carding machine, including a push rod and a support arm. An auxiliary wheel is provided at the end of the support arm, and the auxiliary wheel is rotatably mounted on the support arm. A nut seat is provided at the end of the push rod, and a lead screw is fitted inside the nut seat. A drive motor is provided at one end of the lead screw. A drive rack is also provided on one side of the nut seat, and a drive gear is also provided on one side of the lead screw. The drive gear and the drive rack are meshed. A first commutator is provided on the side of the drive gear away from the lead screw, and the drive gear is rotatably mounted on the first commutator. A drive shaft is provided on the first commutator, and the support arm on the side closer to the lead screw is fitted on the drive shaft.

[0006] Preferably, the bottom of the nut seat is provided with a slider, and the bottom of the slider is provided with a track that cooperates with the slider.

[0007] Preferably, a second commutator is also mounted on the drive shaft, an auxiliary shaft is mounted between the support arms on the side away from the lead screw, a third commutator is provided at one end of the auxiliary shaft, and a connecting shaft is provided between the second commutator and the third commutator.

[0008] Preferably, the push rod is detachably mounted on the nut seat.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] 1. This utility model provides a pusher device for a carding machine. By using a reversing device, the force of the linear motion of the push rod is converted into the force of the support arm flipping. When the push rod pushes, the support arm flips upward, so that the sliver can is unconstrained and easy to push out. When the push rod returns to its original position, the support arm flips upward to complete the constraint of the sliver can, thereby reducing the power equipment of the entire sliver machine and thus reducing the operating cost.

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Examples, such as Figure 1 , Figure 2 As shown, this embodiment aims to ensure the normal and efficient use of the carding machine while reducing the use of drive components. To achieve this objective, the carding machine pusher device provided in this embodiment includes a push rod 1 and a support arm 6. An auxiliary wheel 61 is provided at the end of the support arm 6. The auxiliary wheel 61 is rotatably mounted on the support arm 6. The above structure is a common existing structure, and therefore, it will not be described in detail in this embodiment.

[0018] To ensure normal operation while reducing the number of driving components, it is necessary to link the moving structural parts together to achieve the above objectives. Therefore, in this embodiment, a nut seat 3 is provided at the end of the push rod 1. In this embodiment, the push rod 1 is generally L-shaped, with its short side fixed to the nut seat 3 by bolts. The nut seat 3 is generally cuboid in shape, with a lead screw nut at its end. A lead screw 21 is fitted inside the nut seat 3, and a drive motor 2 is provided at one end of the lead screw 21. A slider 22 is provided at the bottom of the nut seat 3, and a track 4 is provided at the bottom of the slider 22 to cooperate with it. Thus, under the action of the drive motor 2, the nut seat 3 can move back and forth along the lead screw 21, realizing the conveying of the strip drum.

[0019] To achieve linkage, a drive rack 31 is provided on one side of the nut seat 3, and a drive gear 51 is provided on one side of the lead screw 21. The drive gear 51 and the drive rack 31 are meshed. In this embodiment, the meshing means that the drive rack 31 and the drive gear 51 are not meshed for a long time, but rather mesh with the drive gear 51 when the drive rack 31 passes by it. The length of the drive rack 31 is sufficient to allow the drive gear 51 to rotate more than 90°.

[0020] A first commutator 5 is provided on the side of the drive gear 51 away from the lead screw 21. The drive gear 51 is rotatably mounted on the first commutator 5. The commutator is a device that uses the meshing between bevel gears to realize the output angle change. A drive shaft 52 is provided on the first commutator 5. The drive shaft 52 is the output shaft of the first commutator 5. The support arm 6 on the side closer to the lead screw 21 is mounted on the drive shaft 52.

[0021] In this way, driven by the rack 31, the support arm 6 on the side closest to the lead screw 21 can be flipped. The purpose of setting the length of the rack 31 to allow the drive gear 51 to rotate more than 90° is mainly to prevent the support arm 6 from flipping back when it is not supported after it has been flipped to the vertical position. Instead, it is set to flip at an obtuse angle and remain in the support frame of the coiling machine.

[0022] To achieve coordinated control of the auxiliary wheels 61 on both sides of the drum, a second commutator 7 is mounted on the drive shaft 52, and an auxiliary shaft 81 is mounted between the support arms 6 on the side away from the lead screw 21. A third commutator 8 is provided at one end of the auxiliary shaft 81, and a connecting shaft 71 is provided between the second commutator 7 and the third commutator 8. Thus, the connecting shaft 71 serves as the output shaft of the second commutator 7 and the input shaft of the third commutator 8.

[0023] In practical use, when the strip canister needs to be replaced, the drive motor 2 is activated, driving the push rod 1 to move. When the drive rack 31 meshes with the drive gear 51, the support arm 6 is flipped upward. At this time, the push rod 1 also contacts the empty strip canister and continues to move. After the strip canister is transported to the designated position, the drive motor 2 moves in the opposite direction, and the push rod 1 is reset. During the reset process, the drive rack 31 meshes with the drive gear 51, completing the downward flip of the support arm 6, so that the four auxiliary wheels 61 are placed around the strip canister, thereby ensuring the stability of the strip canister when it rotates.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
