Description

Technical Field

[0001] The utility model relates to the technical field of film wrapping devices, in particular to a film wrapping device for apple grafting. Background Art

[0002] Grafting of fruit trees can accelerate the breeding of excellent tree species, enhance the disease resistance of fruit trees, improve the quality of fruits, achieve early high yields in orchards, and improve their ability to adapt to the environment. It is an indispensable technical measure for cultivating fruit seedlings and updating fruit tree varieties. However, the grafting of apple trees still uses the traditional manual method, which has low production efficiency, high labor intensity, low survival rate of grafted seedlings and increasing labor costs. In order to prevent oxidation and water evaporation of the grafting site and ensure the formation of callus tissue at the grafting site, it is very important to seal the grafting site and the cross section of the tassel wood with film.

[0003] A Chinese patent with publication number CN211322140U discloses a film wrapping device for automated apple grafting, which is mainly composed of a grafted seedling clamping part, a slide module part, a driving part of a grafted film roll, a grafted film tension control part, a film cutting part, and a control module. The grafted seedling is fixed by the clamping part, the sliding module moving part is used to achieve horizontal movement, and the driving part of the grafted film roll is used to achieve circular motion in the vertical plane. The tension control part of the grafted film ensures that the grafted film can be stably fixed on the grafted seedling. The grafted film is cut off by the film cutting part to ensure the continuous operation of the device. The device can meet the agronomic requirements of the grafting interface of the grafted seedlings and the film wrapping of the cross section of the tassel wood and the single-layer film wrapping of the buds of the tassel wood, and is an indispensable part of realizing automated grafting.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the above-mentioned device adopts a lifting fixed structure, and the position of the raw material film cannot be adjusted in real time during the film wrapping process. Since the apple tree structure is often uneven in shape, the rotation speed of the raw material roller is uneven, which makes the above-mentioned device prone to film breakage and other problems during the winding process.

[0033] The lifting part 3 includes a lifting bracket 301, a lifting motor 302, a lifting threaded rod 303, a threaded part 304 and a lifting part 305; the bottom of the lifting bracket 301 is connected to the base 1; the top of the base 1 is connected to the lifting motor 302, the top output end of the lifting motor 302 is transmission-connected to the lifting threaded rod 303, the side of the lifting threaded rod 303 is threadedly connected to the threaded part 304; the side of the threaded part 304 is connected to the lifting part 305, and the side of the lifting part 305 is slidingly connected to the lifting bracket 301.

[0034] The damping adjustment member 13 includes an arc-shaped damping member and a threaded adjustment rod. A rotating support bracket is provided on the top of the rotating connecting rod 6. The rotating support bracket is rotatably connected to the threaded adjustment rod. The side of the threaded adjustment rod is threadedly connected to the arc-shaped damping member. The bottom of the arc-shaped damping member is slidably connected to the top of the rotating connecting rod 6. The arc-shaped damping member is in contact and extrusion with the side of the rotating shaft 11.

[0035] A lifting groove is provided on the side of the lifting bracket 301, and the lifting groove is slidably connected to the side of the screw member 304. An anti-slip layer is provided on the inner wall side of the arc-shaped limiter 208.

[0036] A rotating connection piece is provided on the top of the lifting bracket 301 , and the bottom of the rotating connection piece is rotatably connected to the lifting threaded rod 303 .

[0037] In this embodiment, the device can effectively improve the compatibility and stability with the surface of the apple tree.

[0038] Compared with the traditional device, the present device can reduce the risk of raw material film breakage during the film wrapping process through the arc buffer effect, thereby ensuring the film wrapping processing stability of the present device.

[0039] When the device is in working condition, by placing the apple tree raw material on the top of the turntable 204, rotating the bidirectional screw rod 207 can make multiple groups of clamping members 206 slide towards each other, thereby achieving a clamping effect. The structure of the arc-shaped limit member 208 can increase the contact area between the device and the side of the apple tree, thereby improving the clamping stability of the device. The structure of the sliding groove 205 can prevent the clamping member 206 from tilting, thereby ensuring the clamping stability of the device. After the clamping member 206 clamps the side of the apple tree stably, the rotating motor 201 drives the pulley 202 to transmit, and the pulley 202 drives the transmission belt 203 to transmit the turntable 204, thereby achieving a uniform rotation effect of the apple tree.

[0040] During the rotation of the apple tree, the lifting motor 302 drives the lifting threaded rod 303 to rotate, thereby achieving the effect of lifting and lowering the threaded member 304 of the device in the vertical direction, and the lifting member 305 is driven by the threaded member 304 to perform lifting and lowering adjustment, so that the raw material roller 12 is at a suitable height, which is convenient for the device to wrap the film.

[0041] During the wrapping process, the wrapping film is brought into contact with the surface of the apple tree and wrapped around it, so that the raw material roller 12 rotates with the apple tree during the rotation process. When the raw material roller 12 is rotating, the lifting motor 302 drives the threaded member 304 to lift and slide, thereby achieving the continuous winding effect of the device. When the raw material roller 12 is wrapped around a position with a larger diameter of the apple tree, the rotation speed of the raw material roller is accelerated, and the pulling force of the wrapping film is increased. At this time, the structure of the spring 8 and the sliding member 7 can make the rotating connecting rod 6 approach the side of the apple tree under the drive of the rotating driven rod 10 when the pulling force increases, thereby reducing the distance between the raw material roller 12 and the apple tree, and then reducing the rotation speed of the raw material roller 12, which has a buffering effect. When it is wrapped around a position with a smaller diameter on the side of the apple tree, the spring 8 is restored to make the raw material roller 12 away from the apple tree, thereby ensuring the stability of the use of the device. By elastically approaching and moving away from the apple tree, it can be buffered by approaching and moving away when the use speed of the wrapping film suddenly changes, thereby avoiding the problem of the raw material film on the raw material roller 12 breaking due to the sudden increase in pulling force.

[0044] The rotating blocking member is used to prevent the rotating connecting rod 6 from rotating excessively, thereby preventing the raw material roller 12 from contacting the side of the apple tree, thereby ensuring the stability of the device.
