Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to a cotton picker baling bin with an anti-film wrapping function. Background Art

[0002] Cotton cultivation is widespread in my country. Previously, cotton picking relied primarily on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, the development of large-scale mechanized cotton picking has become a major trend in the cotton industry, leading to the emergence of cotton pickers. Using cotton pickers can significantly increase cotton picking speed and generate higher incomes for pickers. The main structure of the cotton picker includes a frame, a picking head, a cotton collecting bin and a baling bin. When in use, the picking head collects cotton, and the collected cotton will be transported to the cotton collecting bin, and then the cotton will be sent to the baling bin by the cotton conveying belt. In the baling bin, the cotton is packed into rolls by baling film, and the initial state of the baling film is a film roll. As the baling progresses, the film roll rotates, the baling film is pulled out from the film roll, and is sent to the baling position by the belt on the film conveying frame. The film output speed and the film delivery speed are theoretically the same, but in practice, in order to prevent the baling film from being deformed or broken, some more will be produced when discharging the film to ensure that there is a margin of baling film. However, when there is too much margin or the baling film on the film conveying frame is not used in time, the baling film at the inlet of the film conveying frame will accumulate and roll back onto the film discharge roller, affecting the normal use of the film. Our company's prior application involves an anti-film winding mechanism using a rigid baffle, but in actual use it was found that the rigid baffle is easy to scratch the baling film, affecting the normal use of the baling bin. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a film-winding prevention mechanism for the baling bin of a cotton picker, which can effectively prevent the baling film at the film outlet roller of the baling bin from rolling back without scratching the baling film.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a cotton picker baling bin with anti-film winding, comprising a bin body, a film feeding roller installed in the bin body, and an anti-film winding mechanism on the film feeding roller. The anti-film winding mechanism is a plurality of film blocking belts and a belt blocking frame wound on the film feeding roller. The belt blocking frame is fixedly connected to the bin body, one end of the film blocking belt is sleeved on the belt blocking frame, and the other end is sleeved on the film feeding roller. A belt pressing mechanism is provided on the film blocking belt, and the belt pressing mechanism includes a pressing roller and a pressing roller frame fixed on the bin body. The two ends of the pressing roller are respectively mounted on the pressing roller frames on the corresponding sides and pressed on the film blocking belt.

[0005] In the above technical solution, a plurality of belt-stopping grooves are provided on the film-feeding roller, and the film-stopping belt is embedded in the belt-stopping grooves.

[0006] In the above technical solution, the depth of the retaining belt limiting groove is consistent with the thickness of the retaining film belt.

[0007] In the above technical solution, the pressure roller frame is provided with a pressure roller adjustment plate, one end of the pressure roller adjustment plate is mounted on the pressure roller frame, and an arc-shaped adjustment groove is provided in the middle, and the pressure roller is mounted on the arc-shaped adjustment groove.

[0008] In the above technical solution, a beam sensor is provided on the inner warehouse wall on one side of the warehouse body.

[0009] In the above technical solution, the barrier film belt is made of elastic material.

[0010] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the present invention adds a film blocking belt to the film feeding roller, and the film blocking belt is embedded in the blocking belt limiting groove of the film outlet roller, so that the film blocking belt can fit the film feeding roller, and the outer diameter at the film outlet roller is consistent with the film outlet roller, which does not affect the normal delivery of the packaging film and effectively prevents the packaging film from winding back. At the same time, the film blocking belt is flexible and will not scratch the packaging film. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is based on the ideal embodiment of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.

[0022] The present invention will be further described with reference to the following drawings:

[0023] like Figures 1 to 8 As shown, a cotton picker baling bin for preventing film winding is provided with a bin body 100, in which a film feeding roller 200 is installed. The film feeding roller 200 is provided with an anti-film winding mechanism 300, and the anti-film winding mechanism 300 is composed of a plurality of film-blocking belts 310 and a belt-blocking frame 320 wound on the film feeding roller 200. The belt-blocking frame 320 is fixedly connected to the bin body 100, and one end of the film-blocking belt 310 is sleeved on the belt-blocking frame 320, and the other end is sleeved on the film feeding roller 200. A belt pressing mechanism 400 is provided on the film-blocking belt 310, and the belt pressing mechanism 400 includes a pressing roller 410 and a pressing roller frame 420 fixed on the bin body 100. The two ends of the pressing roller 410 are respectively mounted on the pressing roller frames 420 on the corresponding sides and pressed on the film-blocking belt 310.

[0024] like Figure 7 As shown, the film feeding roller 200 is provided with a plurality of belt-stopping grooves 210 , and the film-stopping belts 310 are embedded in the belt-stopping grooves 210 .

[0025] The depth of the blocking belt limiting groove 210 is consistent with the thickness of the film blocking belt 310. When the film blocking belt 310 is higher than the plane of the film feeding roller 200, the packaging film at the film blocking belt 310 will be supported, causing slight deformation and affecting the packaging quality. When the film blocking belt 310 is lower than the plane of the film feeding roller 200, the packaging film will be embedded in the blocking belt limiting groove 210 and affect the film feeding.

[0026] like Figure 7 、 8 As shown, the pressure roller frame 420 is provided with a pressure roller adjustment plate 430, one end of the pressure roller adjustment plate 430 is mounted on the pressure roller frame 420, and an arc-shaped adjustment groove 431 is provided in the middle. When the pressure roller 410 is mounted on the arc-shaped adjustment groove 431 and used, the bolts protruding from the adjustment groove 431 can be adjusted to change the degree of pressure of the pressure roller 410 on the packaging film and adjust the tension of the packaging film.

[0027] A beam sensor is provided on the inner wall of one side of the warehouse body 100. The length of a piece of packaging film is 17 to 18 meters, and an induction code is provided at the end. When the beam sensor detects the induction code, a signal indicating that the packaging film has been delivered is obtained.

[0028] The film blocking belt 310 is made of elastic material and will not pop out or rewind while blocking the packaging film.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
