Description

Technical Field

[0001] The utility model relates to the technical field of agricultural residual film recovery and packaging devices, in particular to a self-weight belt roller type residual film recovery and packaging device. Background Art

[0002] In the residual film recycling operation, the packaging of residual film is a very important part. The agricultural recycling balers used mostly use steel roller round bale baling devices. When the residual film enters the baling device, as the steel roller rotates, a film bundle is formed under the action of friction. Since the steel roller is in a state of high-speed rotation during operation, the residual film is prone to be entangled on the surface of the steel roller in the early stage of baling, resulting in jamming between the steel rollers, deformation of the steel rollers, damage to the chain and other problems. The entangled residual film needs to be manually removed, which not only increases the operation risk but also reduces the packaging efficiency. In order to avoid the above problems, belt roller baling devices are gradually being used. However, the general belt roller baling devices have a complex structure, and the quality of the packaged film bundles is also poor, and the actual use effect is not ideal. Summary of the invention

[0003] The purpose of the utility model is to provide a self-weight belt-roller type residual film recovery and packaging device, which overcomes the above-mentioned deficiencies in the prior art and can effectively solve the problems of existing agricultural residual film packaging machinery, such as easy entanglement of film between steel rollers, laborious removal of residual film, increased operational risks, and complex structure of the belt-roller type residual film packaging device and poor quality of the packaged residual film bales.

[0004] The purpose of the utility model is achieved as follows: a self-weight belt roller type residual film recovery and packaging device, comprising a frame, a hydraulic film unloading cylinder, an upper packaging device and a lower packaging device. The upper packaging device is installed at the upper right end of the frame and arranged in an inclined direction with the front higher and the rear lower. The lower packaging device is installed at the lower end of the frame and arranged in a horizontal direction to form a V-shaped gap with the upper packaging device.

DETAILED DESCRIPTION

[0010] The present invention is not limited by the following embodiments, and specific embodiments can be determined according to the technical solution of the present invention and actual conditions.

[0011] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model is further described below in conjunction with the drawings in the embodiment. The embodiment of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model. Based on the embodiment of 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.

[0012] The residual film recovery and packaging device includes a frame 1, a hydraulic film unloading cylinder 10, an upper packaging device 12 and a lower packaging device 13. The upper packaging device 12 is installed at the upper right end of the frame 1 and arranged in an inclined direction with the front higher and the rear lower. The lower packaging device 13 is installed at the lower end of the frame 1 and arranged in a horizontal direction to form a V-shaped gap with the upper packaging device 12. The hydraulic film unloading cylinder 10 is installed on the frame 1 and connected to the upper packaging device 12. The upper packaging device 12 includes three film rolls and a film roll belt 6. The film roll rollers include a front film roll roller 5, an upper film roll roller 7 and a rear film roll roller 8. The front film roll roller 5 is installed at the left end of the upper packaging device 12, the upper film roll roller 7 is installed at the upper right of the front film roll roller 5, and the rear film roll roller 8 is installed at the lower right of the upper film roll roller 7 and is horizontal with the front film roll roller 5. The recovery belt body is installed between the front film roll roller 5, the upper film roll roller 7 and the rear film roll roller 8 to form a film roll belt 6. The recovery belt body is a belt with an uneven surface. The lower packing device 13 includes a self-weight shaft 11, two film transport rollers and a film transport belt 4. The self-weight shaft 11 is installed below the frame 1. The film transport rollers include a front film transport roller 3 and a rear film transport roller 9. The front film transport roller 3 is located at the upper left of the self-weight shaft 11 and is installed at the left end of the frame 1. The rear film transport roller 9 is located at the upper right of the self-weight shaft 11 and is installed at the right end of the frame 1. The recovery belt body is installed between the self-weight shaft 11, the front film transport roller 3, and the rear film transport roller 9 to form a film transport belt 4. The recovery belt body is a belt with a rough surface. The film transport belt 4 is arranged in the horizontal direction.

[0013] Working principle: When the residual film is recovered, the residual film falls off onto the film conveying belt 4 through the matching film stripping device, and then is transported from the left end of the frame to the right end of the frame by the film conveying belt 4. When the residual film is transported to the V-shaped gap formed by the upper packing device 12 and the lower packing device 13, the film roll belt 6 of the upper packing device 12 and the film conveying belt 4 of the lower packing device 13 rotate at different speeds, so that the residual film on the film conveying belt 4 forms a film bundle under the differential effect of the film roll belt 6 and the film conveying belt 4. As the amount of residual film transported by the film conveying belt 4 increases, the diameter of the film bundle gradually increases, which produces pressure on the film conveying belt 4. The self-weight shaft 11 under the frame keeps the film conveying belt 4 in a tensioned state through its own gravity to prevent the film conveying belt 4 from deformation. The film conveying belt 4 also produces pressure on the residual film bundle in a tensioned state, which is beneficial to improving the quality of the packaged film bundle.

[0014] The utility model uses an upper packing device 12 and a lower packing device 13 to pack the residual film from small to large by rolling and rolling. The residual film rolls after packing have good compactness inside and outside and good quality. The equipment width of the packing device matches the width of the residual film. It has the characteristics of simple structure, convenient manufacture, high operation efficiency, and automatic adjustment of belt tension. The film conveying belt 4 can take over the residual film removed by the matching film stripping device, and can effectively reduce the omission of residual film during the packing operation. The horizontal film conveying belt 4 and the film rolling belt 6 with an inclination are used to pack the residual film by rolling the residual film, which is not easy to get stuck. It is also convenient and quick to remove the film roll, with high work efficiency and good safety performance. In addition, the upper packing device 12 and the lower packing device 13 have low equipment cost and are easy to manufacture. After actual testing, the efficiency of residual film packing is high and the comprehensive effect is good.
