Description

Technical Field

[0001] The invention relates to the technical field of gardening cultivation, and in particular to an automatic bundling and winding machine for gardening cutting branches. Background Art

[0002] Cuttings are a common artificial asexual propagation method for plant cultivation. Cuttings are to cut the stems, leaves or roots of plants, prepare cuttings first, and then insert them into the substrate soil or sand. After they take root and become seedlings, they can be transplanted to the field to grow and become independent new plants. Cuttings are divided into stem cuttings, root cuttings and leaf cuttings according to the difference in plant organs used. Large-scale production mostly uses stem cuttings, that is, hard branch cuttings; use plant stem branches, cut them to an appropriate length, and then soak the rooting end in a special agent before implementing the cutting operation. This production model has the advantages of high branch utilization, fast rooting of cuttings, and high survival rate. It is an innovation of traditional cutting technology and is widely used in the field of garden breeding. However, the cutting, sorting and bundling of cuttings, the soaking treatment with special agents, the storage and transportation of cuttings, and the cutting operations all require a lot of manpower, which is not only costly and difficult to control the quality, but also difficult to find labor in the current situation, which seriously restricts large-scale production.

[0049] Example 2

[0050] like Figure 4 As shown, the PE film tension damper includes a clamping swing rod 33, a tension spring 34, and a screw rod 35. One end of the first sleeve 25 is fixedly sleeved with a resistance disk 21. One end of the clamping swing rod 33 is rotatably connected to the fuselage 7. One side wall of the clamping swing rod 33 contacts the outer peripheral wall of the resistance disk 21 to generate friction.

The clamping rocker 33 contacts the outer wall of the first sleeve 25 to generate friction. The pressure between the clamping rocker 33 and the first sleeve 25 is adjusted by adjusting the elastic force of the tensioning spring 34 by rotating the screw 35, thereby realizing the adjustment of the friction force, and then realizing the adjustment of the tension of the PE film 29, which has a wide range of applications.

[0051] The working principle of this embodiment is as follows: preparation work, put the commercial PE film roll 24 on the corresponding first sleeve 25 of the working turntable 11 and lock it through the locking nut 26, then pull out the film head, adjust the damping tension to an appropriate size; turn on the input conveyor 36 and the output device 13; start working, manually put a bunch of branches into the rectangular groove, and move them toward the working turntable 11 along with the input conveyor. During the movement, the branches pass through the O-ring formed by the upper bundling pressure wheel 3 and the lower bundling pressure wheel 4, and the branches are constrained to form a branch bundle, and continue to move toward the working turntable 11 until they move to the PE film 29 where the film head can be wrapped around When the branch bundle reaches one end, the input conveyor is stopped, the film head is wound around the end of the branch, and then the input conveyor is restarted while the rotating motor 37 is turned on. The rotating motor drives the driving wheel 9 to rotate, thereby rotating the working turntable 11, and then rotating the PE film reel 24 relative to the branch bundle. At this time, the branch bundle is tightly bundled together by the PE film during the forward movement, realizing the bundling and bundling function of the branch bundle. The bundled branch bundle continues to move and passes through the working hole 10 and the receiver 12 in turn. The receiver 12 further constrains and fixes the branch bundle. The bundled branches are transported to the cutting table 14 through the output device 13 to segment the branches. Cutting, when cutting, the knife holder 15 is manually operated to make the cutting knife 17 move downward to cut the branch bundle, thereby completing the segmented cutting, and manually placing branches into the rectangular groove continuously. With the conveying movement and the subsequent continuous supply of branches, a continuously output tightly bundled bundle of branches is formed, which can be cut and sheared from the output end and enter the next shearing process. The PE film reel 24 is affected by the PE film 29 tension damper during the rotation process, so that the PE film 29 has a certain tension when it is unfolded, ensuring that the PE film 29 wraps the branches more tightly. It should be noted that only when the film head is wrapped, the input conveyor needs to be stopped, and there is no need to stop during the PE film wrapping process. The input conveyor is stopped to realize continuous production. When the work stops, the working turntable is stopped quickly through the brake mechanism. The operating lever is manually pushed to rotate counterclockwise. The reset spring is compressed, and the lever moves toward the direction of the micro switch and touches the micro switch. The micro switch transmits the signal to the controller. The controller controls the rotating motor to cut off the power. At the same time, the main pull line is pulled to make the friction plates on the two brake levers contact with the side walls of the working turntable and generate friction. The working turntable is stopped quickly by cutting off the power of the rotating motor and the friction force. Then the operating lever is manually released. Under the action of the reset spring, the operating lever is reset. At the same time, under the action of the brake spring, the two brake levers are reset.

[0052] Compared with the prior art, this embodiment has the following beneficial effects:

[0053] The automatic bundling winding and bundling machine can realize the function of rapid mechanized winding and bundling of multiple branches, automatically winding and bundling multiple branches into a bundle. It has a high degree of automation and can replace manual sorting and manual bundling, reduce the amount of labor for bundling, reduce labor intensity, and improve work efficiency. The branches are then cut into uniform lengths by the cutting device to ensure uniform specifications, providing a favorable foundation for subsequent mechanized shearing operations. At the same time, it also makes subsequent processes such as chemical soaking, transportation management, and cutting operations more convenient, providing a favorable foundation; it is conducive to cooperating with related machinery to implement large-scale, standardized, mechanized, and rapid cutting production.

[0054] It is not difficult for those skilled in the art to understand that the present invention includes any combination of the invention content and specific implementation methods of the above specification and the parts shown in the drawings, as well as similar technical extensions. Due to the limited space and to make the specification concise, the various schemes composed of these combinations are not described one by one. For example, the brake device can adopt other specific methods with the same function but similar structure, such as commercial electric bicycle or motorcycle brake devices, etc. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
