The cut films are of uniform size, thus reducing the labor intensity of workers, lowering production costs, and increasing silkworm rearing profits.

Description

Technical Field

[0001] This utility model relates to the field of silkworm breeding equipment, specifically to a quick and labor-saving machine for dividing the film of silkworm baskets. Background Technology

[0002] In sericulture, both the conventional rearing of small silkworms in stacked baskets and the rearing of large silkworms in raised beds require the use of plastic film to line the baskets and beds. This is to prevent silkworms, silkworm excrement, and mulberry leaves from falling off, which could result in the loss or damage of silkworms and contamination of silkworm excrement.

[0003] Currently, most silkworm basket liners are cut by hand using knives or scissors. This method has several drawbacks: First, manual cutting is time-consuming and labor-intensive, resulting in low efficiency. Second, it is difficult to control the precision of manual cutting, leading to inconsistent film sizes. If the film is too small, it cannot completely fill the basket, failing to provide effective protection and pollution prevention. If the film is too large, the edges tend to sag, affecting ventilation and wasting material. Third, improper use of knives during manual cutting can easily cause hand injuries, leading to workplace accidents and posing safety hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems and provide a fast and labor-saving machine for cutting silkworm basket film. To achieve the above objective, this utility model adopts the following technical solution:

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Example:

[0023] This embodiment discloses a fast and labor-saving film cutting machine for silkworm baskets, including two symmetrically arranged support rods (1), a first rotating rod (4), a square frame (6), a second rotating rod (7), a bearing (8), and a crank (9); each support rod (1) has a first mounting seat (3) and a second mounting seat (5) on its front side, and each first mounting seat (3) and second mounting seat (5) has a semi-circular groove, which facilitates the installation of the rotating rod; the bearing (8) is installed in the semi-circular groove of the second mounting seat (5); the left and right ends of the first rotating rod (4) are rotatably connected to the first mounting seat (3), and the first rotating rod (4) is used to sleeve the film roll; the second rotating rod (7) is fixedly connected to the middle of the short side of the square frame (6). Furthermore, the two ends of the second rotating rod (7) protrude from the square frame (6), and the part protruding from the square frame (6) is convenient to connect with the second mounting base (5); the two ends of the second rotating rod (7) are rotatably connected to the second mounting base (5) through bearings (8), and the setting of bearings (8) effectively reduces the friction between the second rotating rod (7) and the second mounting base (5), making the second rotating rod (7) rotate more smoothly; one end of the second rotating rod (7) is fixedly connected to the crank (9), and by rotating the crank (9), the square frame (6) rotates with the second rotating rod (7), which makes it convenient to wrap the film on the square frame (6). Compared with directly rotating the square frame (6) or manually pulling and dividing the film, it is more labor-saving and greatly reduces the labor intensity.

[0024] The two short sides of the square frame (6) are provided with telescopic sleeves (10). By adjusting the length of the telescopic sleeves, the overall length of the square frame (6) can be changed, thereby achieving the purpose of dividing films of different lengths and sizes, so that the equipment can adapt to the film size requirements of different specifications of silkworm baskets.

[0025] The telescopic sleeve (10) includes an inner tube (101) and an outer tube (102). One end of the inner tube (101) is fixedly connected to the short side of the square frame (6). The outer tube (102) is sleeved on the outside of the inner tube (101), and the outer tube (102) is provided with a locking element (103) for fixing the relative position of the inner tube (101) and the outer tube (102). This telescopic sleeve (10) has a simple structure and is easy to adjust. By pulling the inner tube (101) to extend and retract inside the outer tube (102), the length of the telescopic sleeve (10) can be changed, thereby adjusting the length of the square frame (6). After adjustment, the locking element (103) is used to fix the relative position of the inner tube (101) and the outer tube (102) to ensure the stability of the length of the square frame (6), thereby ensuring the accurate size of the divided film.

[0026] The left and right ends of the No. 1 rotating rod (4) are respectively located in the semi-circular grooves of the two No. 1 mounting bases (3).

[0027] The second rotating rod (7) is fixedly connected to the inner ring of the bearing (8), and the outer ring of the bearing (8) is in contact with the inner wall of the semi-circular groove of the second mounting base (5).

[0028] Each support rod (1) has an auxiliary support frame (2) on the front and back sides at the bottom, and the support rod (1) is fixedly connected to the auxiliary support frame (2). The auxiliary support frame (2) can increase the contact area between the support rod (1) and the ground, improve the stability of the entire equipment, prevent the equipment from tipping over during use, and ensure operational safety.

[0029] Mounting base 1 (3) is located above mounting base 2 (5) and is spaced apart along the height direction of the support rod (1). This vertically distributed structure can rationally plan the equipment space and ensure the smooth transfer of the film from the rotating rod 1 (4) to the square frame (6).

[0030] In this embodiment, the length of the square frame (6) is first adjusted according to the required film size. During operation, the locking device (103) on the outer tube (102) is loosened first, and the inner tube (101) is pulled to extend and retract inside the outer tube (102). When the length of the square frame (6) reaches the required size, the locking device (103) is tightened so that the locking device (103) presses against the inner tube (101) to fix the relative position of the inner tube (101) and the outer tube (102), thus completing the adjustment of the length of the square frame (6).

[0031] Next, the film cutting operation is carried out. The film roll is placed on the first rotating rod (4), and the two ends of the first rotating rod (4) are respectively connected to the semi-circular groove of the first mounting base (3) to realize the rotation connection of the first rotating rod (4). Then, one end of the film on the film roll is pulled out, placed on the long side of the square frame (6) and fixed. By rotating the crank (9), the square frame (6) is rotated, and the film is evenly wrapped on the square frame (6). After wrapping to a certain thickness, the film is cut along the long side of the square frame (6) with a blade or scissors. A batch of films with small size differences can be cut out for silkworm breeding. This can ensure the consistency of the film size during the cutting process, thereby achieving a fast, labor-saving and accurate film cutting effect.

[0032] Throughout the operation, the auxiliary support frame (2) ensures the stability of the equipment, the bearing (8) reduces the rotational resistance, and the telescopic sleeve (10) enables flexible adjustment of the film size. The overall equipment is easy to operate and labor-saving, with high cutting efficiency and accurate size, effectively solving many problems of traditional manual film cutting.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
