Description

Technical Field

[0001] The utility model relates to the technical field of cotton picker manufacturing, in particular to a film pressing mechanism for a packing bin of a cotton picker. Background Art

[0002] my country's cotton planting area is quite extensive. In the past, cotton picking mainly relied on manual labor, which was labor-intensive and inefficient. With the continuous improvement of my country's agricultural mechanization level, the development of large-scale machine-picking cotton has become the general trend of my country's cotton industry, so cotton pickers have appeared on the market. By using cotton pickers, the speed of cotton picking can be effectively increased, creating higher income for cotton 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 conveyor belt, in which 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, and the baling film is pulled out from the film roll, and the film roll gradually becomes thinner. When not in use, the diameter of the film roll can reach 250mm, and when it is almost used up, only 90mm is left. At first, the film roll is thicker and has a larger circumference. When a unit length of the film roll is pulled out, the angle required to rotate the film roll is smaller, and the weight is larger, so the film roll rotates stably when the baling film is pulled out, but as the baling film is used, the film roll gradually becomes thinner and lighter, and the rotation speed of the film roll becomes faster and faster. At this time, the film roll cannot rotate regularly and jumps.

[0003] Moreover, the packaging film is used to pack cotton, so it has glue on the inside. The packaging film with a shorter production date will not stick together, but the film roll is thicker and cannot be guaranteed to be used up every time. As time goes by, the layers of the packaging film will stick together, affecting its use. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a film pressing mechanism for the baling bin of a cotton picker, which can ensure that the film roll does not shake when it is pulled out, and can also press the film roll to facilitate pulling apart the baling film stuck by glue.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a film pressing mechanism for a baling bin of a cotton picker, comprising a fixed rod installed on a baling bin body, the fixed rod being provided with a mounting seat, the mounting seat being provided with a pressure wheel seat, the pressure wheel seat being provided with a pressure wheel, the mounting seat being hinged to the fixed rod, and the mounting seat being provided with an elastic member, the elastic member being able to pull the mounting seat to rotate relative to the fixed rod, and the pressure wheel seat being hinged to one end of the mounting seat.

[0006] In the above technical solution, the mounting seat includes a base and an adjusting seat, the base is hinged on the fixing rod, and the base and the adjusting seat are connected via long holes and bolts.

[0007] In the above technical solution, the elastic member is a torsion spring arranged at the hinge between the mounting seat and the fixing rod.

[0008] In the above technical solution, the elastic member is a spring, and two ends thereof are respectively mounted on the mounting seat and a spring seat arranged on the bin body.

[0009] In the above technical solution, a torsion plate is provided on one end of the fixing rod.

[0010] In the above technical solution, the pressing wheel seat is provided with two pressing wheels, and the angle between the two pressing wheels is 70-90°.

[0011] To sum up, the technical solution of the utility model has the following beneficial effects compared with the traditional technical means: during actual use, the utility model does not contact the film roll at first. As the packaging film is pulled out, the diameter of the film roll is reduced from 250mm to 150mm. At this time, the fixing rod is rotated to lower the mounting seat, and the pressure wheel presses the film roll under the action of the elastic part, so that the film roll can be ensured not to shake when being pulled out, and the film roll can be pulled out more stably.

[0012] At the same time, the film pressing mechanism presses the outermost packaging film on the film roll, exerts a downward pressure on the packaging film on the film roll, and prevents the multiple layers of packaging film from being pulled out together after being glued together, thereby ensuring the normal use of the packaging film.
