Technical Field
[0001] This utility model relates to the field of mushroom bags, and in particular to a roll film bag making device, which is mainly used to improve the convenience of bag making and the effect of tying. Background Technology
[0002] In the cultivation of edible fungi using bag substrate, bagging the substrate, such as sawdust, is an important but tedious production process. Currently, manual labor is predominant, which is inefficient, labor-intensive, and requires significant manpower and space. A combination of mechanical and manual methods is also used, such as horizontal edible fungi substrate bagging machines, where the bags are manually fitted onto the discharge cylinder during feeding, resulting in low efficiency and accuracy. Fully automated methods exist, first using a bag-making device to form the bags, then using a bag-opening device to open the bags, and finally using a bag-fitting device to fit the bags onto the discharge cylinder. All of these methods require sealing one end of the film bag, and then sealing the other end with a rope after the substrate is filled. However, some edible fungi require both ends of the film bag to be sealed with rope for easy opening later. While existing technologies include bag-making devices that tie the film bag with rope before cutting to meet the bagging requirements of edible fungi, this is not the only approach. However, the following drawbacks still exist: First, it is not convenient to operate when different lengths of film bags are required; second, the position of the film bag tying rope and the cutting position cannot be accurately controlled, resulting in poor tying effect. Summary of the Invention
[0003] The purpose of this invention is to overcome the defects and problems of existing technologies, such as inconvenience in making film bags of different lengths and poor tie-up effect, and to provide a roll film bag making device that is convenient for making film bags of different lengths and has a good tie-up effect.
[0004] To achieve the above objectives, the technical solution of this utility model is: a roll film bag making device, comprising:
[0005] The binding mechanism, bag cutting mechanism, and bag pulling mechanism are arranged sequentially along the direction of bag movement.
[0006] The bag-pulling mechanism is used to clamp and release the film bag conveyed by the bag delivery tube and to drive the film bag to move horizontally.
[0007] The rope-tying mechanism is used to tie the end of the film bag by a rope after the bag-pulling mechanism clamps the end of the film bag.
[0008] The bag-cutting mechanism is used to cut the film bag after the bag-pulling mechanism moves the tied rope of the film bag a set length.
[0009] The bag-pulling mechanism includes a horizontally arranged first slide rail and grippers for clamping and releasing the film bag, the grippers being slidably mounted on the first slide rail.
[0010] The bag cutting mechanism includes a bag cutting section for cutting the film bag and a bag cutting cylinder for moving the bag cutting section.
[0011] The horizontal distance between the position where the bag-cutting part cuts the film bag and the position where the rope-tying mechanism ties the film bag is 5 to 30 mm.
[0012] The cross-section of the bag delivery tube is elliptical.
[0013] The rope-tying mechanism includes a ring turntable, a rope-grabbing mechanism, a knotting mechanism, a rope-pulling mechanism, and a rope-cutting mechanism. The rope-grabbing mechanism is installed on the ring turntable, which is fitted onto the outside of the bag-feeding tube.
[0014] Both the rope-cutting mechanism and the knot-tying mechanism are located inside the annular turntable.
[0015] It also includes a bag folding mechanism, which includes a pair of first conveyor rollers and a pair of second conveyor rollers. The first conveyor roller and the second conveyor roller are arranged perpendicularly. The first conveyor roller is fitted with a rubber ring for folding the film bag. The film bag is placed in the conveying pipe after passing through the first conveyor roller and the second conveyor roller in sequence.
[0016] It also includes a bag feeding mechanism, which includes a rotating shaft for mounting the film bag and a guiding mechanism. The rotating shaft is mounted on the frame and a brake disc is mounted on the rotating shaft. The guiding mechanism includes a second slide rail mounted vertically on the frame, a mounting base slidably mounted on the second slide rail, multiple first guide rollers mounted on the frame, and multiple second guide rollers mounted on the mounting base. A sensor for controlling the operation of the brake disc is mounted on the mounting base. After passing through the first guide rollers and the second guide rollers, the film bag is located in the bag folding mechanism.
[0017] A third guide roller is provided between the bag feeding mechanism and the bag folding mechanism.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. In the roll film bag making device of this utility model, a tie-up mechanism, a cut-up mechanism, and a pull-up mechanism are arranged sequentially along the moving direction of the film bag. First, the pull-up mechanism clamps the end of the film bag, then the tie-up mechanism ties the end of the film bag, then the pull-up mechanism moves the film bag horizontally to a set position, then the cut-up mechanism cuts the film bag, and finally the pull-up mechanism releases the film bag to complete the film bag making. The above design not only ensures that the tied-up effect of the film bag is good, but also allows the set position to be adjusted according to actual needs, thus facilitating the production of film bags of different lengths.
[0020] 2. In this utility model's roll-film bag-making device, the horizontal distance between the cutting section's position for cutting the film bag and the binding section's position for binding the film bag is 5-30mm. This not only ensures a good binding effect but also results in a fan-shaped film bag, facilitating subsequent bagging. The bag conveying tube has an elliptical cross-section, which helps maintain the input shape of the film bag, facilitating subsequent clamping by the bag-pulling mechanism, binding by the binding mechanism, and cutting by the bag-cutting mechanism. Therefore, this utility model offers excellent binding effect, high reliability, and ease of use.
[0021] 3. In this utility model, a roll film bag making device includes a bag folding mechanism comprising a pair of first conveyor rollers and a pair of second conveyor rollers. The first and second conveyor rollers are arranged perpendicularly. A rubber ring for folding the film bag is fitted onto the first conveyor roller. The film bag is located between the pair of first conveyor rollers and is folded inward by the rubber ring. After passing between the pair of second conveyor rollers, it can be folded again and conveniently conveyed to the bag delivery tube. Therefore, this utility model is convenient to use and has high reliability.
[0022] 4. In this utility model, a film-rolling bag-making device includes a brake disc mounted on the rotating shaft for mounting the film bags. The guiding mechanism comprises a second slide rail vertically mounted on the frame, a mounting base slidably mounted on the second slide rail, multiple first guide rollers mounted on the frame, and multiple second guide rollers mounted on the mounting base. A sensor controlling the operation of the brake disc is mounted on the mounting base. When conveying the film bags, the guiding mechanism moves upward along the second slide rail. When the conveying of the film bags stops, the guiding mechanism resets. At this time, the brake disc is controlled by the sensor to stop the rotating shaft from rotating. The bag-feeding mechanism of the above structure has good bag-feeding stability and high reliability. A third guide roller is provided between the bag-feeding mechanism and the bag-folding mechanism to facilitate the folding of the film bags and their stable input into the bag-feeding tube. Therefore, this utility model has stable operation and high reliability. Attached Figure Description

Detailed Implementation
[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0038] See Figure 1 and Figure 2A roll film bag making device includes: a rope-tying mechanism 2, a bag-cutting mechanism 3, and a bag-pulling mechanism 1 arranged sequentially along the moving direction of the film bag 5; the bag-pulling mechanism 1 is used to clamp and release the film bag 5 conveyed by the bag delivery tube 4 and to drive the film bag 5 to move horizontally; the rope-tying mechanism 2 is used to tie the end of the film bag 5 with a rope after the bag-pulling mechanism 1 clamps the end of the film bag 5; the bag-cutting mechanism 3 is used to cut the film bag 5 after the bag bag 5 is moved a set length by the bag-pulling mechanism 1.
[0039] In application, the end of the film bag 5 is first clamped by the bag pulling mechanism 1, and then the end of the film bag 5 is tied by the rope tying mechanism 2. Then, the film bag 5 is moved horizontally to the set position by the bag pulling mechanism 1, and then the film bag 5 is cut by the bag cutting mechanism 3. Finally, the film bag 5 is released by the bag pulling mechanism 1 to complete the production of the film bag 5. The above design adjusts the set position by fixing the rope tying position and the bag cutting position and controlling the movement of the bag pulling mechanism. This not only ensures that the tied rope effect of the produced film bag is good, but also facilitates the production of film bags of different lengths.
[0040] Further, see Figure 3 The bag-pulling mechanism 1 includes a horizontally arranged first slide rail 101 and a gripper 102 for clamping and releasing the film bag 5. The gripper 102 is slidably mounted on the first slide rail 101.
[0041] Specifically, the first slide rail 101 is horizontally mounted on the frame 8. A slider 103 is mounted on the first slide rail 101. The slider 103 is connected to the gripper cylinder 104. The gripper cylinder 104 is used to control the gripper 102 on it to clamp and release the film bag 5. A drive assembly is installed on the frame 8 directly above the first slide rail 101 to drive the slider 103 to move horizontally along the first slide rail 101. The drive assembly includes a belt 105 and a pulley 106. The belt 105 is connected to the slider 103, and the pulley 106 is connected to the drive motor.
[0042] In application, first control the slider 103 to drive the gripper cylinder 104 to move towards the bag conveying tube 4, then control the gripper 102 to clamp the film bag 5, then control the rope tying mechanism 2 to tie the end of the film bag 5, then control the slider 103 to drive the film bag 5 to the set position, the bag length can be controlled by the set position, and then the film bag 5 is cut by the bag cutting mechanism 3.
[0043] Further, see Figure 6 , Figure 7 and Figure 10The bag-cutting mechanism 3 is located between the rope-tying mechanism 2 and the bag-pulling mechanism 1. For example, both the rope-tying mechanism 2 and the bag-pulling mechanism 1 are horizontally arranged, with the bag-cutting mechanism 3 located below the opposite side of the rope-tying mechanism 2 and the bag-pulling mechanism 1, and the bag-cutting mechanism 3 is vertically arranged. The bag-cutting mechanism 3 includes a bag-cutting part for cutting the film bag 5 and a bag-cutting cylinder 301 for moving the bag-cutting part. The bag-cutting cylinder 301 is fixedly mounted on the frame 8, and the output end of the bag-cutting cylinder 301 is connected to the mounting bracket 302. The mounting bracket 302 is connected to the bag-cutting part. The bag-cutting part can be a bag-cutting scissors 304 controlled by a first cylinder 303, or it can be a cutter controlled by a first cylinder 303.
[0044] Furthermore, the horizontal distance between the position where the bag-cutting part cuts the film bag 5 and the position where the rope-tying mechanism 2 ties the film bag 5 is 5 to 30 mm.
[0045] Further, see Figure 4 and Figure 5 The bag conveying tube 4 is mounted on the frame 8. The cross-section of the bag conveying tube 4 is elliptical to keep the film bag 5 folded, which facilitates the subsequent gripping by the bag pulling mechanism 1 and the binding by the rope tying mechanism 2. To facilitate the passage of the film bag 5 through the bag conveying tube 4, multiple elongated grooves can be opened on the bag conveying tube 4.
[0046] Further, see Figure 4 and Figure 5 The rope-tying mechanism 2 includes an annular turntable 21, a rope-grabbing mechanism 22, a knotting mechanism 23, a rope-pulling mechanism 24, and a rope-cutting mechanism 25.

[0050] See Figures 6 to 8The rope-pulling mechanism 24 includes a rope-pulling cylinder 241 and a rope-pressing cylinder 242. The rope-pulling cylinder 241 is mounted on the frame 8, and its output end is connected to one side of the mounting plate 243.

The output end of the rope-pressing cylinder 242 is connected to a first pressing block 244, and a second pressing block 245 is connected to the lower part of the other side of the mounting plate 243. A rope-passing hole 246 is provided on the mounting plate 243 between the first pressing block 244 and the second pressing block 245. A rope-guide hole 9 is provided on the frame 8. The rope passes through the rope-passing hole 246 and the rope-guide hole 9 in sequence and is then clamped by the rope-grabbing mechanism 22. For a detailed description of the use of the rope-pulling mechanism 24, please refer to the utility model disclosed in Chinese Patent No. CN216775672U, authorized on June 21, 2022, which discloses an automatic rope-tying machine.

The film bag 5 is placed in the conveying pipe 4 after passing through the first conveyor roller 601 and the second conveyor roller 602 in sequence.
[0052] In application, the film bag 5 is located between a pair of first conveyor rollers 601 and is folded inward by the rubber ring 603. After passing between a pair of second conveyor rollers 602, it can be folded again and easily conveyed to the bag conveying tube 4.
[0053] Further, see Figure 11 and Figure 12 The roll film bag making device also includes a bag feeding mechanism 7, which includes a rotating shaft 701 for mounting the film bag 5 and a guiding mechanism. The rotating shaft 701 is mounted on the frame 8, and a brake disc 702 is mounted on the rotating shaft 701. The guiding mechanism includes a second slide rail 703 vertically mounted on the frame 8, a mounting seat 704 slidably mounted on the second slide rail 703, multiple first guide rollers 705 mounted on the frame 8, and multiple second guide rollers 706 mounted on the mounting seat 704.

[0054] In application, when conveying the film bag 5, the guide mechanism moves upward along the second slide rail 703. When the conveying of the film bag 5 stops, the guide mechanism resets. At this time, the brake disc 702 is controlled by the sensor to stop the rotating shaft 701 from rotating. The bag feeding mechanism 7 with the above structure has good bag conveying stability and high reliability.
[0055] Further, see Figure 11 A third guide roller 10 is provided between the bag feeding mechanism 7 and the bag folding mechanism 6 to facilitate the folding of the film bag and its stable input into the bag feeding tube.
