Description

Technical Field

[0001] This utility model relates to the field of edible fungi machinery, and in particular to a film rolling bagging device. Background Technology

[0002] In the cultivation of edible fungi using bag substrate, bagging the substrate, such as sawdust, is an important but tedious process. Currently, manual methods are predominantly used, which are not only inefficient and labor-intensive, but also require a large workforce and space. Fully automated methods are also employed, first using a bag-making device to create the bags, then using a bag-opening device to open the bags, and finally using a bag-attaching device to attach the bags to the discharge cylinder. While this improves efficiency, it still has the following drawbacks: for thinner rolls of film, the film cannot be stably conveyed to the sealing and cutting device, resulting in poor conveying stability. This also affects the subsequent bag-making process, thus degrading the quality of the mushroom bags. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a roll film bagging device is provided. Guide rollers facilitate the unloading of the roll film, while multiple feeding rollers ensure smooth unrolling and conveying. Pressure rollers tighten the roll film, preventing wrinkles during rapid conveying and effectively reducing the scrap rate. Compared to existing technologies, this device ensures stable film conveying during bag making, thus improving bag-making efficiency. Therefore, this utility model offers high conveying stability.

[0017] 2. In this utility model's film roll bagging device, the feeding rollers are arranged in an alternating pattern, allowing the film roll to pass through multiple feeding rollers before being conveyed. Simultaneously, the feeding rollers provide sufficient friction, effectively preventing the film roll from slipping off the rollers due to poor adhesion during conveying. By incorporating springs, tension is provided, ensuring the pressing roller remains below the guide roller and feeding roller. This prevents the pressing roller from rotating upwards due to excessive film conveying speed, which would degrade its pressing effect. Therefore, this utility model has a simple structure and high stability.

[0018] 3. In this utility model's film rolling and bagging device, the feeding mechanism is coupled with the film rolling drive through paired feeding rollers. The linear velocity of the feeding roller surface is consistent with the film rolling output speed, and the film rolling output speed can be adjusted by adjusting the feeding roller speed. A clamping block is included, which can move on the mounting frame via an elastic element, thereby preventing gear jamming. Therefore, this utility model has high reliability and stable operation.

[0019] 4. In this utility model's roll film bagging device, a first telescopic device drives a forming blade to move up and down to cut the roll film. Simultaneously, a second telescopic device drives a heating strip to move upward, allowing the heating strip to enter the hot strip hole, thereby heat-sealing the roll film. This design is not only simple in structure, but the entire mechanism only requires up and down movement, occupying little space and facilitating control. Therefore, this utility model has a simple structure and occupies little space.

[0020] 5. In this utility model's roll-up bagging device, an upper lifting cylinder is installed on the upper part of the support, and its output end is connected to an upper suction cup. A lower lifting cylinder is installed on the lower part of the support, and its output end is connected to a lower suction cup. During operation, the upper lifting cylinder drives the upper suction cup to move downwards, and the lower lifting cylinder drives the lower suction cup to move upwards. The upper and lower suction cups cooperate to open the bag. The bag-opening mechanism of the above structure occupies little space and has high reliability. Therefore, this utility model occupies little space and has high reliability.

[0021] 6. In this utility model's film-rolling bagging device, the first and second sets of claws, which are closed, can be inserted into the mushroom bag opened by the opening mechanism via a bag-dispensing cylinder. Then, the extendable end of the bag-spreading cylinder is controlled to extend, causing the first and second sets of claws to separate and open the mushroom bag. Subsequently, the bag-dispensing cylinder moves to the outlet of the discharge cylinder, and the opened mushroom bag is placed onto the discharge cylinder. Once the mushroom bag is in place, the extendable end of the bag-dispensing cylinder is controlled to retract, causing the first and second sets of claws to rotate and separate. Throughout the entire working process, the closing, opening, and bag-dispensing actions of the first and second sets of claws are all controlled by two cylinders, resulting in high reliability in bag retrieval. Therefore, this utility model has high reliability in bag retrieval. Attached Figure Description

A pressure roller 24 is located below the guide roller 22 and is arranged relative to the feed roller 32 located at the head. A limit post 26 is connected to one side of the support rod 25.

[0034] In this embodiment, one end of the roll film is first placed in the feeding mechanism 3 after passing around the guide roller 22, the pressing roller 24, and multiple feeding rollers 23 in sequence. Then, the feeding mechanism 3 drives the roll film to move. After the roll film moves, it is cut open and sealed at the bottom by the sealing and cutting mechanism 4 to form a mushroom bag. Then, the opening mechanism 5 opens the mushroom bag and moves it to the outlet of the discharge cylinder by the bagging mechanism 6, and the opened mushroom bag is put on the discharge cylinder.

One end of the roller passes through the clamping block 35 and is fixedly connected to the feeding driven gear 34. The feeding driven gear 34 is meshed with the feeding power gear 33. The feeding motor 36 is mounted on the mounting bracket 31 and is connected to the feeding power gear 33 through the pulley group 37. The bottom of the clamping block 35 is elastically engaged with the mounting bracket 31 through the elastic element 38.

[0038] The elastic element 38 includes a connecting bolt 381, a connecting spring 382, ​​and a connecting nut 383. The nut of the connecting bolt 381 is located on the lower side of the mounting bracket 31.

By starting the feeding motor 36, the pulley is driven to rotate. The pulley transmits power to the feeding roller 32 through the belt. Through gear meshing, the two feeding rollers 32 rotate in different directions, so that the film roll can pass through the gap between the two feeding rollers 32.

[0056] The bag-discharging cylinder 63 can extend the first set of claws 66 and the second set of claws 67 into the mushroom bag opened by the opening mechanism 5. Then, the extendable end of the bag-supporting cylinder 65 is controlled to extend, causing the first set of claws 66 and the second set of claws 67 to separate and open the mushroom bag. Then, the bag-discharging cylinder 63 moves to the outlet of the discharge cylinder and puts the opened mushroom bag onto the discharge cylinder. When the mushroom bag is in place, the extendable end of the bag-discharging cylinder 63 is controlled to retract, causing the first set of claws 66 and the second set of claws 67 to move laterally. After the first set of claws 66 contacts the mushroom bag, it turns open and then returns to its original position. At the same time, the extendable end of the bag-supporting cylinder 65 is controlled to extend, causing the first set of claws 66 and the second set of claws 67 to close. Then, the linear module 61 moves the closed first set of claws 66 and the second set of claws 67 to the opening mechanism 5 to perform the clamping of the next mushroom bag.
