[0002] Mushroom bags are generally rod-shaped and are also often referred to as mushroom sticks, mushroom bags, or edible mushroom cultivation bags. They are containers specifically designed for growing fungi (such as mushrooms, ganoderma lucidum, and agrocybe cylindracea). Their design aims to provide a suitable environment for the growth of fungi, promoting the reproduction of hyphae and the development of fruiting bodies. The main materials of mushroom bags include plastic materials such as polyethylene (PE) and polypropylene (PP). These materials have good air permeability and moisture retention, which can meet the growth requirements of fungi. At the same time, they also have certain durability and anti-aging properties and can be reused.

[0003] During the growth process of edible fungi, some waste gases such as carbon dioxide are generated. Timely discharging the waste gases generated during the growth process can create a more suitable environment for the growth of hyphae and avoid the inhibition of hyphae growth caused by the accumulation of waste gases. Reasonable punching and film pasting operations can ensure that the hyphae obtain sufficient oxygen supply and a suitable growth environment, thereby promoting their rapid growth and reproduction and increasing the yield of edible fungi.

Specific embodiments

[0024] The following will describe the specific implementation manners of the present invention in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0025] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, an automatic punching and film - sticking machine for mushroom sticks includes a workbench 1. On the workbench 1, there is a conveyor belt 2 for conveying mushroom bags 8 one by one. Above the conveyor belt 2, there is an installation frame 3. On the installation frame 3, there are a fixing mechanism 4, a punching mechanism 5, and a film - sticking mechanism 6. The fixing mechanism 4 is used to fix the mushroom bags 8 conveyed one by one on the conveyor belt 2. The punching mechanism 5 is used to punch holes in the mushroom bags 8 fixed by the fixing mechanism 4. The film - sticking mechanism 6 is used to paste adhesive tapes on the mushroom bags 8 after the punching mechanism 5 has completed punching. Specifically, an automatic punching and film - sticking machine for mushroom sticks improves production efficiency and the quality of finished products. The workbench 1 is constructed of sturdy and durable stainless - steel material, with its surface specially treated, being easy to clean and corrosion - resistant. The workbench 1 ensures the stable operation of the conveyor belt 2 and reduces the deviation of the mushroom bags 8 during transportation. The conveyor belt 2 is made of food - grade material, non - toxic and harmless, meeting the hygiene standards. The speed of the conveyor belt 2 is adjustable to adapt to different production requirements. The installation frame 3 has a stable structure to ensure the precise operation of the fixing mechanism 4, the punching mechanism 5, and the film - sticking mechanism 6. The fixing mechanism 4 uses a pneumatic or electric clamping device to fix the mushroom bags 8 on the conveyor belt, preventing displacement during the punching process. The clamping force is adjustable to adapt to mushroom bags 8 of different sizes and materials. The punching mechanism 5 can precisely punch holes in the mushroom bags 8 according to a preset program, and the aperture size, hole pitch, and punching depth are all adjustable. The punching process is fast and consistent, reducing damage to the mushroom bags 8 and being beneficial to the subsequent growth of hyphae. The film - sticking mechanism 6 follows the punching mechanism 5 and automatically and precisely pastes the pre - cut adhesive tape on the punched area. The adhesive tape is made of environmentally friendly material, having good air permeability and sealing performance, which can effectively prevent contamination by miscellaneous bacteria and promote the directional growth of hyphae. The tape - sticking process is controlled by a precise servo motor to ensure that each piece of adhesive tape fits perfectly without bubbles or wrinkles. This automatic punching and film - sticking machine for mushroom sticks, with its high - efficiency, precision, and intelligent features, significantly improves production efficiency and product quality.

[0026] Combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the film pasting mechanism 6 includes a first cylinder 61 arranged on the mounting frame 3. The output end of the first cylinder 61 is fixedly connected with a movable plate 62. On the front surface of the movable plate 62, there are a tape releasing wheel 63 for adhesive tape, an automatic adhesive stripping plate 64, an adhesive tape re - sticking mechanism 65, and a tape winding wheel 66 for adhesive tape. On the back surface of the movable plate 62, there is a driving mechanism 7 for driving the tape releasing wheel 63 and the tape winding wheel 66 for adhesive tape to rotate. Specifically, the film pasting mechanism 6 ensures that the adhesive tape can be accurately and efficiently pasted on the punched mushroom bags. The first cylinder 61 is installed on the mounting frame 3, and the up - and - down movement of the movable plate 62 is realized through pneumatic control. This not only ensures the stability of the pasting operation but also facilitates fine - tuning according to the height and punching position of the mushroom bag 8. The movable plate 62 serves as a platform for carrying and fixing various components. The movable plate 62 is made of a lightweight and strong material to ensure good stability during rapid movement. Key components in the pasting process are arranged on its front surface, while the back surface is used to install the driving mechanism 7, achieving a compact and efficient structure. The tape releasing wheel 63 for adhesive tape is responsible for smoothly releasing the adhesive tape from the adhesive tape roll. To ensure the smooth supply of the adhesive tape. The automatic adhesive stripping plate 64 is designed on the movable plate 62 and can automatically strip the release paper or protective film on the back of the adhesive tape when the adhesive tape passes through, exposing the adhesive surface of the adhesive tape and preparing it for pasting on the mushroom bag 8. The precise positioning and timely action of the automatic adhesive stripping plate 64 are the keys to ensuring the pasting quality. The adhesive tape re - sticking mechanism 65 is located behind the automatic adhesive stripping plate 64 and is used to slightly press or heat - treat (depending on the type of adhesive tape) the adhesive surface of the adhesive tape before it is pasted on the mushroom bag 8 to enhance the adhesion between the adhesive tape and the mushroom bag 8 and ensure firm pasting and not easy to fall off. After the adhesive tape completes the pasting task, the tape winding wheel 66 for adhesive tape is responsible for recycling and winding up the waste release paper or protective film, etc. The tape winding wheel 66 for adhesive tape works in coordination with the tape releasing wheel 63 for adhesive tape, and through precise rotational speed matching, maintains the smoothness and efficiency of the entire pasting process. The driving mechanism 7 is located on the back surface of the movable plate 62 and uses a transmission device such as a motor or a reducer to provide stable rotational power for the tape releasing wheel 63 for adhesive tape and the tape winding wheel 66 for adhesive tape. Through a precise control system, the driving mechanism 7 can adjust the rotational speed according to production requirements to ensure that the supply speed of the adhesive tape matches the pasting speed.

[0027] Combined with Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, the adhesive tape re - sticking mechanism 65 includes a first servo - motor 651 disposed on the movable plate 62. The output end of the first servo - motor 651 is fixedly connected to a fixed pressing block 652. On one side of the bottom of the fixed pressing block 652, there is a rubber pressing wheel 653, and on the other side of the bottom of the fixed pressing block 652, there is a sponge smoothing wheel 654. Above the rubber pressing wheel 653 on the fixed pressing block 652, there is a first positioning sensor 655, which is used to detect whether the adhesive tape is directly below the rubber pressing wheel 653. Specifically, the adhesive tape re - sticking mechanism 65, as the core part of the film - sticking mechanism 6, fully considers the stability and uniformity of the adhesion between the adhesive tape and the mushroom bag. The first servo - motor 651, as the power core of the adhesive tape re - sticking mechanism 65, with its characteristics of high precision and high response speed, ensures that the fixed pressing block 652 and its attached components can move precisely according to the preset program and speed. The application of the first servo - motor 651 not only improves the automation degree of the tape - sticking process but also ensures the stability and consistency of the tape - sticking quality. The fixed pressing block 652 is used to carry and fix the rubber pressing wheel 653 and the sponge smoothing wheel 654. The rubber pressing wheel 653 is made of high - quality rubber material, having good elasticity and wear resistance. During the tape - sticking process, the rubber pressing wheel 653 is responsible for gently pressing the adhesive tape onto the surface of the mushroom bag 8, making the adhesive tape closely adhere to the mushroom bag through appropriate pressure. The selection of rubber material not only ensures the buffering effect during the pressing process but also avoids unnecessary damage to the mushroom bag 8. The sponge smoothing wheel 654, which is adjacent to the rubber pressing wheel 653, is responsible for further smoothing the surface of the adhesive tape after the adhesive tape is pressed down, eliminating possible air bubbles and wrinkles. The selection of sponge material not only ensures the smoothing effect but also has a certain softness, avoiding excessive extrusion of the adhesive tape and the mushroom bag 8. The first positioning sensor 655 is disposed on the fixed pressing block 652, directly above the rubber pressing wheel 653. The first positioning sensor 655 monitors the position of the adhesive tape in real - time to ensure that the adhesive tape is accurately directly below it before the rubber pressing wheel 653 presses down, effectively preventing tape - sticking failure or quality problems caused by the deviation of the adhesive tape position.

[0028] Combined with Figure 2 , Figure 3 and Figure 5As shown, the driving mechanism 7 includes a tape winding motor 71 disposed on the back surface of the movable plate 62. The output end of the tape winding motor 71 is fixedly connected with a rotating pulley 72. A synchronous belt 73 is connected to the rotating pulley 72, and the synchronous belt 73 is connected to the adhesive tape unwinding pulley 63 and the adhesive tape winding pulley 66. Specifically, the driving mechanism 7 ensures the smooth supply and recovery of the adhesive tape during the gluing process. The tape winding motor 71 is installed on the back surface of the movable plate 62, which not only ensures the stable transmission of power but also avoids interfering with the gluing process. By controlling the rotation speed and direction of the motor, precise adjustment of the supply and recovery speed of the adhesive tape can be achieved. The rotating pulley 72 serves as a connecting bridge between the tape winding motor 71 and the synchronous belt 73, and its design fully considers the transmission efficiency and stability. The rotating pulley 72 is made of high-strength and wear-resistant materials, and its surface is specially treated to increase the friction with the synchronous belt 73, ensuring smooth and reliable power transmission. At the same time, the diameter and number of teeth of the rotating pulley 72 are also carefully calculated to match the rotation speed of the motor and the transmission requirements of the adhesive tape. The synchronous belt 73 is responsible for transmitting the power of the tape winding motor 71 to the adhesive tape unwinding pulley 63 and the adhesive tape winding pulley 66. The synchronous belt 73 is made of high-strength, wear-resistant, and anti-aging materials, has good flexibility and elasticity, and can adapt to the transmission requirements of different speeds and directions. It not only simplifies the transmission structure but also improves the transmission efficiency and reduces noise and vibration.

[0029] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when pasting the adhesive tape on the mushroom bag 8, first, the tape feeding motor 71 drives the adhesive tape feeding wheel 63 to release the adhesive tape. The adhesive tape is peeled off by the automatic tape peeling plate 64, then pasted onto the mushroom bag 8 by the adhesive tape re-sticking mechanism 65, and finally, the remaining adhesive tape is wound up by the adhesive tape winding wheel 66. Specifically, after receiving the pasting instruction, the control system starts the tape feeding motor 71. The tape feeding motor 71, as the power source, rotates quickly and smoothly, driving the synchronous belt 73 to operate through the rotating pulley 72 connected to its output end. The operation of the synchronous belt 73 drives the rotation of the adhesive tape feeding wheel 63, and the adhesive tape feeding wheel 63 then starts to release the pre-installed adhesive tape. The adhesive tape is pulled out at a stable speed and tension, ready to enter the next stage of processing. As the adhesive tape moves, it first passes through the automatic tape peeling plate 64. The automatic tape peeling plate 64 uses mechanical or pneumatic principles to precisely peel off the release paper or protective film on the back of the adhesive tape at the moment when the adhesive tape passes through. This process is fast and accurate, ensuring that the sticky surface of the adhesive tape is completely exposed and ready to contact the mushroom bag 8. The adhesive tape from which the release paper has been peeled continues to move forward until it reaches the adhesive tape re-sticking mechanism 65. Here, the first servo motor 651 drives the fixed pressing block 652 and the rubber pressing wheel 653 and the sponge smoothing wheel 654 on it to move downward. The rubber pressing wheel 653 first gently presses down the adhesive tape to make it contact the surface of the mushroom bag 8 and generate a preliminary adhesive force. Immediately afterwards, the sponge smoothing wheel 654 further smooths the adhesive tape to eliminate possible bubbles and wrinkles, ensuring a tight fit between the adhesive tape and the mushroom bag 8. During this process, the first position sensor 655 monitors the position of the adhesive tape in real time to ensure the accuracy of pasting. After pasting the mushroom bag 8, the remaining adhesive tape (including the peeled release paper or protective film) continues to move forward and finally reaches the adhesive tape winding wheel 66. The adhesive tape winding wheel 66 rotates under the drive of the tape feeding motor 71 to wind up the waste adhesive tape and its release paper and other items. This not only realizes the effective recycling and management of waste, but also ensures the continuity and high efficiency of the gluing process. As the winding wheel rotates continuously, a new adhesive tape can continue to be released and used for pasting the next mushroom bag.

[0030] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the punching mechanism 5 includes a mounting plate 51 disposed on the movable plate 62. A second servo motor 52 is provided on the mounting plate 51. The output end of the second servo motor 52 is fixedly connected to a punching needle 53. A second positioning sensor 54 is disposed on one side of the second servo motor 52 on the mounting plate 51. The second positioning sensor 54 is used to detect whether the mushroom bag 8 is directly below the punching needle 53. Specifically, the punching mechanism 5 ensures that the mushroom bag 8 can complete the punching operation accurately and without error. The mounting plate 51 is disposed on the movable plate 62, providing a solid support for the punching operation. The mounting plate 51 is made of high-strength and corrosion-resistant materials to ensure its stability and durability in a long-term and high-frequency working environment. The second servo motor 52, as the power source of the punching mechanism 5, ensures that the punching needle 53 can move precisely according to the preset program and speed. This not only improves the punching accuracy and efficiency but also makes the entire punching process smoother and more reliable. The punching needle 53 is responsible for forming the required holes in the mushroom bag 8. The punching needle 53 is made of high-quality alloy material, having a sharp edge and excellent wear resistance, which can extend the service life while ensuring the punching quality. The second positioning sensor 54 is mounted on the mounting plate 51, adjacent to one side of the second servo motor 52. Its main function is to monitor the position of the mushroom bag 8 in real time, ensuring that the mushroom bag 8 is accurately positioned directly below it before the punching needle 53 presses down. This effectively prevents punching failure or quality problems caused by the position deviation of the mushroom bag 8. The second positioning sensor 54 adopts a high-precision and high-sensitivity photoelectric or laser sensor, which can quickly and accurately capture the position information of the mushroom bag 8 and feedback it to the control system for real-time adjustment. During the punching operation, the punching mechanism 5 cooperates closely with other components such as the movable plate 62 and the first cylinder 61 to jointly complete the punching task. First, the movable plate 62 moves to the designated position according to the instruction issued by the control system; then, the second servo motor 52 is started to drive the punching needle 53 to move downward; when the punching needle 53 approaches the mushroom bag 8, the second positioning sensor 54 monitors the position of the mushroom bag 8 in real time and makes fine adjustments; finally, the punching needle 53 accurately penetrates the mushroom bag 8 to form a hole. During the whole process, the coordinated work of each component ensures the accuracy and efficiency of punching.

[0031] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the fixing mechanism 4 includes a second cylinder 41 disposed on the mounting bracket 3, and the output end of the second cylinder 41 is fixedly connected with fixing clamping plates 42 for clamping both ends of the mushroom bag 8. Specifically, the fixing mechanism 4 ensures that the mushroom bag 8 can maintain a stable position and posture during the punching and film pasting processes, thereby improving the operation accuracy and efficiency. The fixing mechanism 4 is installed on the mounting bracket 3, and the mounting bracket 3 serves as the support frame of the entire mechanism, not only providing sufficient strength and stiffness, but also ensuring the stability and reliability of the fixing mechanism 4 during the working process. The second cylinder 41 serves as the power source of the fixing mechanism 4. Through the telescopic movement of its piston rod, the second cylinder 41 provides the necessary clamping force for the fixing clamping plates 42. The second cylinder 41 adopts high-quality pneumatic components, featuring fast response speed, high control accuracy, stable and reliable operation, etc. It can be quickly started and adjust the magnitude of the clamping force as required according to the instructions of the control system to adapt to mushroom bags 8 of different specifications and materials. The fixing clamping plates 42 are the components in the fixing mechanism 4 that directly contact the mushroom bag 8 and apply the clamping force. They are usually designed as a pair of symmetrical structures, located at both ends of the mushroom bag 8 respectively. The inner surface of the fixing clamping plates 42 may be covered with anti-slip materials or adopt special surface treatment techniques to increase the friction with the mushroom bag 8 and prevent sliding or deviation during the punching and film pasting processes. In addition, the opening size and shape of the fixing clamping plates 42 can also be adjusted according to the specific dimensions of the mushroom bag 8 to ensure the tightness and stability of clamping. During the process of clamping the mushroom bag 8, the fixing mechanism 4 realizes the precise adjustment of the clamping force through the precise control of the second cylinder 41. After the mushroom bag 8 is placed at the designated position, the control system issues an instruction to start the second cylinder 41, causing the fixing clamping plates 42 to gradually approach and clamp both ends of the mushroom bag 8. The magnitude of the clamping force will be dynamically adjusted according to factors such as the material, thickness and size of the mushroom bag 8 to ensure that the mushroom bag 8 is neither damaged nor can it move stably. At the same time, in order to prevent the mushroom bag 8 from being deformed or damaged due to excessive clamping, the control system also sets an upper limit value for the clamping force for protection. The fixing mechanism 4 closely cooperates with other mechanisms (such as the punching mechanism 5, the film pasting mechanism 6, etc.) to jointly complete the punching and film pasting operations on the mushroom bag 8. During the punching process, the fixing mechanism 4 ensures the stable position of the mushroom bag 8, enabling the punching needle to accurately penetrate into the designated position; during the film pasting process, the fixing mechanism 4 continues to maintain the stable posture of the mushroom bag 8 so that the film pasting mechanism 6 can smoothly paste the adhesive tape at the punching position. This collaborative working method greatly improves the overall performance and operation efficiency of the automatic punching and film pasting machine for mushroom sticks.

[0032] Combined with Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a damper 631 is provided on the adhesive tape unwinding wheel 63. Specifically, the damper 631 is provided on the adhesive tape unwinding wheel 63 to further optimize the transmission performance of the adhesive tape. The main function of the damper 631 is to slow down the sudden acceleration or deceleration of the adhesive tape during transmission, ensuring that the adhesive tape can move forward smoothly at a constant speed. This helps to avoid tension fluctuations caused by speed changes, thereby reducing the risk of the adhesive tape breaking or running off track. By adjusting the damping force of the damper 631, precise control of the adhesive tape tension can be achieved. Appropriate tension is crucial for maintaining the flatness of the adhesive tape and ensuring its tight fit with the mushroom bag 8. The damper 631 can dynamically adjust the tension size according to actual needs to meet the challenges under different working conditions. The application of the damper 631 also helps to extend the service life of the adhesive tape unwinding wheel 63 and other related components. By reducing mechanical shock and stress concentration, the damper can protect these components from damage, reducing maintenance costs and replacement frequencies.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
