Description

Technical Field

[0001] The utility model relates to a residual material collecting mechanism of a cotton plucking machine. Background Art

[0002] With the development of textile machinery and people's pursuit of the quality of textile products, the reciprocating cotton plucking machine is the first process in the entire cleaning and combing production line process. The reciprocating cotton plucking machine can perform various actions such as reciprocating, lowering, turning and other intelligent cotton plucking. The main function of the cotton plucking machine is to grab and loosen the raw cotton and fiber, so that the raw materials can be fully mixed in the cleaning and combing process, and the linear density of the fiber regeneration strips can be uniform, so as to produce high-quality products. Its processing objects are mainly raw material packages transported from cotton tying factories or chemical fiber manufacturers. Its main task is to loosen the compressed fiber blocks in the raw material packages into smaller fiber bundles, while avoiding fiber damage and impurity fragmentation, removing most of the impurities and defects in the raw materials and some short fibers, while avoiding the loss of spinnable fibers and fully mixing raw materials of different compositions and grades to ensure the uniformity of yarn quality. Therefore, the cotton plucking machine has a good market prospect.

[0003] At present, in the working process of the existing reciprocating cotton plucking machine (for example, a reciprocating cotton plucking machine disclosed in Chinese patent publication number CN209428654U), a lot of cotton residue will remain on the cotton plucking beaters of the reciprocating cotton plucking machine. After the reciprocating cotton plucking machine moves once, the cotton residue on the cotton plucking beaters falls directly on the ground. After the reciprocating cotton plucking machine completes the cotton plucking operation, the cotton residue on the ground is cleaned and collected manually. This manual cleaning and collection method is not only cumbersome to operate and increase labor costs, but also during the working process of the cotton plucking machine, the cotton residue on the ground is easy to float in the air, affecting the workshop environment. For this reason, it is necessary to improve this technical problem, and this case is born. Utility Model Content

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] like Figures 1 to 3 As shown, the utility model is a cotton plucking machine residual material collection mechanism, which is improved on the basis of a reciprocating cotton plucking machine disclosed in Chinese Patent Publication No. CN209428654U, comprising a cotton conveying trough 101, a tower body 102 that can reciprocate along the cotton conveying trough 101, and a lifting seat 103 that can perform lifting movement along the tower body 102 in a vertical direction, wherein the lifting seat 103 is connected to a cotton plucking arm 104, and the specific improved structure is that residual material suction grooves 105 are arranged in parallel on the left and right sides of the cotton plucking arm 104, and a suction notch 106 is arranged on one end of each residual material suction groove 105 facing the cotton plucking arm, and each residual material suction groove 105 is driven to lift and lower by a lifting assembly arranged on the tower body 102, and each residual material suction groove 105 is connected to a material extraction assembly, and the material extraction assembly sucks the residual material suction groove, and a negative pressure is formed in the residual material suction groove, and the cotton residual material is sucked into the residual material suction groove through the suction notch. During operation, after the cotton grabbing arm moves a stroke to the left or right (the moving stroke is the laying length of the cotton bale), the residual material suction groove on the left or right side moves downward to the bottom of the cotton grabbing arm, and the residual material suction groove sucks away the residual cotton falling from the cotton grabbing arm, thereby realizing the recovery of the residual cotton. There is no need for manual cleaning and collection afterwards, and it can effectively prevent the residual cotton from floating in the air.

[0017] It should be noted that during use, when the cotton grabbing arm moves one stroke to the right, the residual material suction groove on the right side moves downward, while the residual material suction groove on the left side remains stationary (located at the upper left side of the cotton grabbing arm); conversely, when the cotton grabbing arm moves one stroke to the left, the residual material suction groove on the left side moves downward, while the residual material suction groove on the right side remains stationary (located at the upper right side of the cotton grabbing arm).

[0018] In this embodiment, a baffle 107 is fixed at the lower end of the suction slot 106, and the baffle 107 is inclined toward the side away from the cotton grabbing arm 104. A flow port 108 is formed between the upper end of the baffle 107 and the top of the residual material suction slot 105 to facilitate the flow of cotton residual material. A cavity is formed between the baffle and a side wall of the residual material suction slot away from the cotton grabbing arm. A suction connection port 109 for connecting to the material extraction component is provided at the lower part of the end of the residual material suction slot 105 away from the cotton grabbing arm. The suction connection port 109 is directly opposite to the position of the baffle 107, that is, the suction connection port is connected to the cavity. By arranging a baffle at the suction slot, the baffle is located between the suction connection port and the suction slot, and the cotton residual material entering from the suction slot enters the cavity from the flow port and is then output from the suction connection port. In this process, the cotton residual material will not be directly concentrated in the suction connection port, which effectively avoids the blockage of the suction connection port.

[0019] In this embodiment, the suction slot is in the shape of an elongated strip and extends along the length direction of the residual material suction slot.

[0020] In this embodiment, the material extraction assembly includes a material storage box 110, a material extraction fan 111 and a material extraction pipe 112. The material storage box 110 is installed on the side of the tower body 102, and the material extraction fan 111 is installed on the front side wall of the material storage box 110. The air outlet of the material extraction fan 111 is connected to the inside of the material storage box 110, and the air inlet of the material extraction fan 111 is connected to one end of the material extraction pipe 112, and the other end of the material extraction pipe 112 is connected to the suction connection port 109. When working, the material extraction fan extracts the air in the residual material suction groove, so that a negative pressure is formed in the residual material suction groove, so as to facilitate the cotton residual material to enter the residual material suction groove, and the cotton residual material is sent into the material storage box along the extraction pipe.

[0021] In this embodiment, the lifting assembly is a linear module 113 vertically arranged at the front end of the tower body 102, and the rear end of the residual material suction groove 105 is fixedly connected to the moving end of the linear module 113. It should be noted that the linear module is an existing mature technology, which includes a screw rod, a motor, a slide rail, a slider, etc., and its specific structure and working principle will not be repeated here.

[0022] In this embodiment, the cross section of the residual material suction groove 105 is rectangular.

[0023] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0024] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0025] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
