Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and particularly to a fully automatic track-type film rolling, covering and sealing device. Background Art

[0002] In China, the output of organic wastes such as livestock and poultry manure, food waste, tail vegetables, and crop straw is high, but the resource utilization rate is relatively low, resulting in serious environmental problems. Composting is an important means for the treatment and resource utilization of organic wastes. The air flow film composting technology has become one of the main methods for treating large-output solid wastes such as large-scale and intensive farms due to its remarkable odor-blocking effect. This technology covers the air flow film on the stack of organic wastes, and then performs forced ventilation and aeration. After a certain period of fermentation, the organic wastes can be fermented into nutrient-rich crop fertilizers to achieve resource reuse. However, at present, in many areas, when covering and uncovering the film, it is often carried out manually or with mechanized film rolling and covering equipment. When pulling the film manually, there are problems such as huge human labor loss, low efficiency, and lack of flexibility. The mechanized film rolling and covering equipment has high energy consumption costs, high operation complexity, and requires professional personnel for maintenance and management. It cannot be installed and removed at any time, which is not conducive to the development of the current air flow film composting technology. Summary of the Invention

[0025] The following is combined with Figures 1 - 3 Describe the specific structure and working principle of the fully automatic orbital winding and film sealing device of the present invention.

[0026] As Figure 1 shown, the fully automatic orbital winding and covering film sealing device includes a compost film winding and unwinding component 100 and a compost film traction component 200. The compost film winding and unwinding component 100 is used for winding and releasing the compost film; the compost film traction component 200 includes a film support 210, a support frame 220 and a driving assembly. The film support 210 is arranged above the compost body along the width direction of the compost body, and the film support 210 is connected to the free end of the compost film; the support frame 220 is arranged along the length direction of the compost body; the driving assembly is connected to the film support 210 and the support frame 220, and the driving assembly is used to drive the film support 210 to move along the length direction of the support frame 220 so as to cover, wind and seal the compost film.

[0027] The fully automatic orbital winding and covering film sealing device provided by the present invention has the advantage of simple structure compared with the traditional multi-frame structure, greatly reducing the use of materials, reducing the manufacturing cost of the equipment, and at the same time simplifying the installation and maintenance time of the equipment, making it more convenient to use.

[0028] In an embodiment of the present invention, as Figure 1 shown, the compost film traction component 200 includes two support frames 220, and the two support frames 220 are arranged at intervals along the width direction of the compost body, and the distance between the two support frames 220 is greater than the width of the compost body. By adopting a split support frame, the fully automatic orbital winding and covering film sealing device obtains a wider applicability and can adapt to the operation requirements of compost bodies with different widths. Specifically, during use, the distance between the two support frames 220 can be flexibly adjusted according to the actual width of the compost body to match the width of the compost body, so as to ensure the accuracy and effectiveness of the film covering operation. The adoption of the split support frame not only expands the use range of the device, but also improves its versatility and flexibility in different scenarios.

[0029] Preferably, the support frame 220 is a hollow frame body to reduce the weight of the support frame 220.

[0030] In an embodiment of the present invention, as Figure 1As shown, the support frame 220 includes a support frame body 221 and a mounting portion 222. The support frame body 221 is arranged along the length direction of the compost heap, and the mounting portion 222 is provided at the top of the support frame body 221 and extends along the length direction of the compost heap. The width of the mounting portion 222 is greater than the width of the support frame body 221, and the support frame body 221 and the mounting portion 222 form a frame with a T-shaped cross-section. By making the width of the mounting portion 222 greater than the width of the support frame body 221, a relatively wide mounting platform is formed in the width direction on the upper part of the support frame 220, providing sufficient mounting space for key components such as the slide rail 230 and the rack 260, ensuring that the drive assembly can be stably mounted on the mounting portion 222 and having sufficient space for adjustment and maintenance. In addition, this design of width difference helps to reduce the overall weight of the support frame 220, making the support frame 220 lighter while maintaining its structural strength, facilitating movement and installation between different compost heaps, and improving the flexibility and applicability of the fully automatic orbital winding and film covering device.

[0031] In an embodiment of the present invention, the compost film traction component 200 includes two drive assemblies, and the two drive assemblies are correspondingly arranged on the upper part of the mounting portion 222.

[0032] In an embodiment of the present invention, the fully automatic orbital winding and film covering device further includes a control component (not shown), and the control component is electrically connected to the two drive assemblies and the compost film winding and unwinding component 100. The control component is used to control the two drive assemblies and the compost film winding and unwinding component 100 to work together to ensure that the motor speeds of the two drive assemblies are matched. The control component includes a PLC controller. Of course, the specific type of the control component is not limited to this, and other types of controllers can also be used.

[0033] In an embodiment of the present invention, as Figure 2 shown, the drive assembly includes a slide rail 230, a base plate 240, and a drive mechanism. The slide rail 230 is arranged along the length direction of the compost heap on the upper part of the mounting portion 222. Specifically, the slide rail 230 is bolted to the mounting portion 222. The slide rail 230 adopts a modular design and is installed by splicing multiple sections. The length of the slide rail 230 can be flexibly spliced and adjusted according to the length of the compost heap to meet the film covering requirements of composting facilities of different scales and shapes.

[0034] The base plate 240 is a plate-like structure, and the base plate 240 is arranged horizontally. A slider is arranged at the bottom of the base plate 240, and a slot is arranged at the bottom of the slider. The slider can be slidably clamped on the slide rail 230 to achieve sliding cooperation between the base plate 240 and the slide rail 230. The clamping cooperation between the slider and the slide rail 230 not only greatly simplifies the installation and disassembly process of the fully automatic track-type roll film sealing device, but also provides convenience for the fixation and sealing of the compost film. During installation, the operator can quickly adjust the position and number of the slider according to the shape, size and specific requirements of the compost body, and easily achieve accurate coverage and sealing of the film, thereby significantly improving the film coating quality and operating efficiency.

[0035] The two ends of the film support 210 are respectively connected to the corresponding base plate 240. Preferably, the film support 210 and the base plate 240 are detachably connected to facilitate the installation and removal of the fully automatic track-type roll-covering film sealing device. The operator can quickly adjust the position and angle of the film support 210 to ensure that the compost film can accurately cover the surface of the pile, further improving the flexibility and adaptability of the operation. The driving mechanism is connected to the base plate 240 and the mounting portion 222, and the driving mechanism is used to drive the base plate 240 to slide along the slide rail 230. Figure 1 As shown, when the driving mechanism starts and pushes the base plate 240 to the right, the compost film retracting component 100 releases the compost film according to the instruction, so that the compost film can smoothly cover the surface of the pile. On the contrary, when the driving mechanism drives the base plate 240 to move to the left, the compost film retracting component 100 starts to rotate in the opposite direction, efficiently rewinds the compost film, and realizes the film peeling operation of the pile.

[0036] It should be noted that the size design of the slider needs to be optimized according to the actual width of the pile. To ensure the stability of the compost film during the covering process, the width and height of the slider should match the size of the slide rail 230 to ensure that the slider slides smoothly on the slide rail 230. The material of the slider should be wear-resistant and corrosion-resistant to extend its service life.

[0037] In one embodiment of the present invention, Figure 2As shown in the figure, the driving mechanism includes a first driving motor 250 and a rack 260. The first driving motor 250 is vertically arranged on the substrate 240. The housing of the first driving motor 250 is bolted to the substrate 240. The substrate 240 is provided with a through hole. The rotating shaft of the first driving motor 250 extends downward after passing through the through hole. The gear 270 is located below the substrate 240 and is sleeved on the rotating shaft of the first driving motor 250. The rack 260 is arranged on the upper part of the installation part 222 along the length direction of the heap body. The rack 260 and the slide rail 230 are arranged at intervals along the width direction of the support frame 220. The rack 260 is located outside the slide rail 230. The rack 260 meshes with the gear 270. The meshing of the rack 260 and the gear 270 can provide strong driving power, ensuring that there is no slipping phenomenon during the composting film winding and releasing process, and guaranteeing the continuity and stability of the operation. When the first driving motor 250 is started, the rotating shaft of the first driving motor 250 drives the gear 270 to rotate. The gear 270 meshes with the rack 260 to convert the rotation into linear motion and drive the substrate 240 to slide along the slide rail 230.

[0038] Preferably, the rack 260 is an inclined rack 260 and the gear 270 is an inclined gear 270, so that during the rotation of the gear 270, the tooth surfaces of the rack 260 and the gear 270 will gradually enter and gradually disengage from meshing. This progressive contact method greatly reduces the impact and vibration, making the entire transmission process smoother and the equipment operation quieter. In addition, the meshing of the inclined rack 260 and the inclined gear 270 belongs to line contact. During the operation of the fully automatic track-type winding and covering film device, a certain pulling force is required for the winding and releasing of the composting film. Especially when dealing with a larger area or heavier composting film, higher requirements are put forward for the bearing capacity of the driving mechanism; the high bearing capacity of the inclined rack 260 and the inclined gear 270 can ensure that there is no slipping or damage due to excessive load, thus extending the service life of the driving mechanism.

[0039] It should be noted here that the specific type of the driving mechanism is not limited to the combination of the first driving motor 250 and the rack 260, and it can also be a combination of a motor, a chain and a sprocket.

[0040] It also should be noted here that the powers of the two first driving motors 250 are the same. The power of the first driving motor 250 is specifically determined according to the length of the heap body and the width of the film. The power of the second driving motor 130 and the first driving motor 250 need to be matched to ensure the same speed of the film during the winding, releasing and covering processes. The selection of the motor power also needs to consider the material and thickness of the film to ensure that the motor can provide sufficient torque to realize the smooth winding, releasing and covering of the film.

[0041] In a preferred embodiment of the present invention, the slide rail 230 and the support frame 220 are slidably engaged along the width direction of the support frame 220. Specifically, a plurality of guide rails extending along the width direction of the support frame 220 are provided on the upper part of the support frame 220, and the plurality of guide rails are arranged at intervals along the length direction of the support frame 220. A plurality of card slots are provided at the bottom of the slide rail 230, and the plurality of card slots are respectively clamped on the plurality of guide rails, so that the slide rail 230 and the support frame 220 are slidably engaged. At least two linear driving members are provided on the upper part of the support frame 220. The linear driving members are connected to the slide rail 230 and the support frame 220, and the linear driving members are used to drive the slide rail 230 to slide along the width direction of the support frame 220. Preferably, the linear driving member is an electric push rod or an oil cylinder. When the substrate 240 slides along the slide rail 230, the linear driving member is in a closed state, so that the rack 260 and the slide rail 230 maintain a fixed distance. Of course, a locking mechanism (positioning pin) can also be provided to fix the position of the slide rail 230. When the substrate 240 moves to a section of the slide rail 230 away from the compost film winding and unwinding component 100, the substrate 240 can be disassembled so that the substrate 240 is separated from the slide rail 230. The substrate 240 can be used for other film winding and sealing devices. At this time, the side edge of the compost film is placed between the rack 260 and the slide rail 230, and the linear driving member is controlled to drive the slide rail 230 to approach the rack 260 from the initial position, so as to clamp the side edge of the compost film between the rack 260 and the slide rail 230, realizing the film sealing process. When it is necessary to wind the film, the linear driving member is controlled to drive the slide rail 230 back to the initial position and then the substrate 240 is installed on the slide rail 230. In an embodiment of the present invention, as Figure 1 shown, the first driving motors 250 of the two driving mechanisms are both electrically connected to the control component, and the control component controls the two first driving motors 250 to rotate synchronously, thereby ensuring that the two ends of the film support 210 rotate synchronously, realizing the smooth winding and unwinding of the film. Since the two ends of the film support 210 are respectively connected to the two substrates 240, and the movement of the substrate 240 is controlled by the driving mechanism, the synchronous operation of the two driving mechanisms directly determines the movement state of the film support 210. When the two first driving motors 250 rotate synchronously, the two ends of the film support 210 will simultaneously receive driving forces of the same magnitude and direction, thereby realizing the smooth linear movement of the film support 210. This smooth movement mode is crucial for the winding and unwinding of the compost film, and can effectively avoid problems such as distortion, slack or excessive stretching of the compost film caused by the asynchronous movement of the two ends of the film support 210, ensuring that the compost film always remains flat and uniform during the winding and unwinding process.

[0042] When covering a larger area of the pile, the film support 210 needs a longer stroke to complete the covering of the compost film; the control component controls the two first drive motors 250 to rotate synchronously to ensure that the film support 210 moves smoothly throughout the entire stroke, so that the compost film can be evenly covered on the surface of the pile, effectively blocking the leakage of odor and improving the quality of compost. When rolling up the compost film, the control component controls the two first drive motors 250 to rotate synchronously so that the compost film can be evenly wound on the reel 120, avoiding wrinkles or looseness of the compost film, and facilitating the storage and reuse of the compost film.

[0043] In one embodiment of the present invention, Figure 1 As shown, the membrane support 210 is a rod-shaped structure, and the free end of the compost film is fixed to the membrane support 210. The membrane support 210 moves along the slide rail 230 to drive the compost film to roll up the compost film or release the compost film. The membrane support 210 with a rod-shaped structure reduces the use of materials as much as possible while meeting the functional requirements; this not only reduces the manufacturing cost of the equipment, but also reduces the weight of the membrane support 210 itself, thereby reducing the burden on the drive mechanism and improving the operating efficiency of the entire device. The membrane support 210 is arc-shaped, and the height in the middle of the membrane support 210 is greater than the height at both ends of the membrane support 210. In actual applications, the middle part of the pile is usually of greater height, while the edge part is relatively lower; if the film support 210 adopts a straight design, when the film support 210 passes over the pile, it may collide or interfere with the middle part of the pile, resulting in coating failure or equipment damage, while the arc-shaped film support 210 perfectly solves this problem; the film support 210 with a greater middle height passes through the middle part of the pile, and the lower parts at both ends can smoothly avoid the edge of the pile, ensuring that the entire film support 210 smoothly completes the coating or film collection operation, and will not be affected by the irregular shape of the pile. This setting method not only improves the adaptability and versatility of the film support 210, but also enhances the reliability and stability of the entire fully automatic track-type roll-covering and sealing device. When faced with piles of different shapes and sizes, the film support 210 can rely on its unique shape to smoothly complete the tasks of winding and releasing the compost film, ensuring that the pile is evenly covered or exposed.

[0044] In a preferred embodiment of the present invention, a distance sensor is provided on the film support 210. Preferably, the distance sensor is located at the central position of the film support 210 to ensure that the distance from the middle part of the stack to the film support 210 can be accurately measured. The distance sensor is electrically connected to the PLC controller. The distance sensor is used to measure the distance between the stack and the film support 210 and send it to the PLC controller through wired or wireless communication. The PLC controller processes and analyzes the received signal and compares it with a pre-set safety distance value. When the received distance value is less than the safety distance value, the PLC controller determines that the film support 210 is about to collide or interfere with the stack, and immediately issues an instruction to control the first drive motor 250 and the second drive motor 130 to stop rotating simultaneously. The film support 210 stops moving under the action of the drive mechanism, avoiding collision with the stack and protecting the safety of the equipment and the stack.

[0045] In a preferred embodiment of the present invention, the control component further includes a prompting unit, and the prompting unit is a buzzer, an indicator light or a display. When the received distance value is less than the safety distance value, the PLC controller controls the prompting unit to output a prompting message, and the prompting message can be a sound, a light or a text. After receiving the prompting message, the operator can quickly respond according to the prompting message, such as manually adjusting the position of the film support 210, processing the stack or checking the operating state of the equipment, etc., to ensure the normal operation and operation quality of the fully automatic orbital winding and covering film device. This not only improves the safety and reliability of the equipment, but also reduces the downtime and maintenance cost caused by equipment failures, and improves the working efficiency of the entire device.

[0046] In a preferred embodiment of the present invention, a connecting frame 280 is provided on the upper part of the substrate 240, and both ends of the film support 210 are detachably connected to the corresponding connecting frames 280. In this embodiment, the height of the connecting frame 280 is fixed. The provision of the connecting frame 280 can provide a stable connection platform for the film support 210, enabling the film support 210 to be reliably connected to the substrate 240, facilitating installation, disassembly and adjustment operations. Specifically, the connecting frame 280 and the film support 210 are connected by bolts or can also be connected by snap fasteners. By adopting the detachable connection method, it not only facilitates the installation and disassembly of the film support 210, but also improves the operation efficiency. In actual operation, the operator can quickly adjust the position and angle of the film support 210 according to the shape, size of the stack and the specific requirements of film covering to ensure that the composting film can accurately cover the surface of the stack.

[0047] In a preferred embodiment of the present invention, the connecting frame 280 is a telescopic bracket. By using a telescopic bracket, the height of the film bracket 210 can be adjusted, which can effectively avoid the collision or interference between the film bracket 210 and the stack. Especially when facing stacks of different shapes and heights, the operator can flexibly adjust the height of the film bracket 210 according to the actual situation, ensuring that the composting film can accurately cover the surface of the stack, and improving the flexibility and adaptability of the operation.

[0048] Preferably, the telescopic bracket is a cylinder or an oil cylinder. The cylinder or the oil cylinder is vertically arranged. The cylinder body of the cylinder or the oil cylinder is connected to the substrate 240 by bolts, and the telescopic rod of the cylinder or the oil cylinder is connected to the film bracket 210. When the detected distance value is less than the safety distance value, the PLC controller controls the cylinder or the oil cylinder to extend, increasing the height of the film bracket 210 to ensure that the film bracket 210 can pass through smoothly. By automatically adjusting the height of the film bracket 210 through the cylinder or the oil cylinder, the operation efficiency of the fully automatic orbital winding and covering film device is significantly improved. The operator does not need to manually adjust the position of the film bracket 210, reducing the risk of manual intervention and operation errors.

[0049] In a preferred embodiment of the present invention, a tension sensor is provided on the film bracket 210. The tension sensor is connected to the free end of the composting film and is electrically connected to the PLC controller. The tension sensor is used to detect the tension applied to the composting film. When the tension value detected by the tension sensor is greater than the preset tension value, it indicates that the first driving motor 250 and the second driving motor 130 do not work in coordination, and the tension on the composting film is too large, and there is a risk that the composting film will be broken. The PLC controller controls the first driving motor 250 and the second driving motor 130 to stop rotating to prevent the composting film from being broken due to excessive tension, protecting the safety of the equipment and the composting film. By real-time monitoring the tension of the composting film and timely adjusting the running state of the motor, not only the operation efficiency is improved, but also the maintenance and management of the equipment are facilitated. The operator can timely discover and solve potential problems according to the tension value detected by the tension sensor, avoid the equipment running in an abnormal state, and extend the service life of the equipment.

[0050] In a preferred embodiment of the present invention, a clamping member is provided on the film bracket 210. The clamping member is used to fix the free end of the composting film. During use, only need to open the clamping member and clamp the free end of the composting film in the clamping member, then the fixation of the composting film can be achieved. There is no need to spend a lot of time for adjustment and fixation like the traditional fixation method, which not only improves the operation efficiency, but also reduces problems such as loosening or falling off of the composting film caused by insecure fixation, improving the quality and stability of the film covering. Preferably, the clamping member is a clip. Of course, it can also be other fixing mechanisms.

[0051] In an embodiment of the present invention, as Figure 3As shown, the compost film winding and unwinding component 100 includes a base 110, a winding drum 120, and a second driving motor 130. The winding drum 120 is rotatably arranged on the base 110, and the compost film is wound around the outer peripheral surface of the winding drum 120. The second driving motor 130 is arranged on the upper part of the base 110, and the rotating shaft of the second driving motor 130 is connected to the winding drum 120. The second driving motor 130 is used to drive the winding drum 120 to rotate.

[0052] The rotation speeds of the first driving motor 250 and the second driving motor 130 need to be precisely matched through a PLC controller. The PLC controller adjusts the rotation speeds of the first driving motor 250 and the second driving motor 130 in real time according to the preset program and the information fed back by the sensors to ensure that the speeds of the compost film during winding, unwinding, and covering are consistent. The accuracy of speed matching needs to be controlled within ±5% to avoid wrinkles or tears in the film material due to speed mismatch.

[0053] In an embodiment of the present invention, rollers are provided at the bottom of the base 110. The provision of rollers facilitates the movement of the compost film winding and unwinding component 100 to facilitate the adjustment of the position of the compost film winding and unwinding component 100. Preferably, the rollers are provided with a braking mechanism to facilitate the fixation of the position of the compost film winding and unwinding component 100.

[0054] Working principle of the fully automatic orbital winding, covering, and sealing film device: During the film covering operation, first, one end of the compost film is fixed on the winding drum 120, and then the first driving motor 250 and the second driving motor 130 are started. The second driving motor 130 drives the winding drum 120 to rotate, unfolds the compost film, and spreads it on the compost pile; meanwhile, the two first driving motors 250 drive the slider to slide along the length direction of the slide rail 230 through the gear 270, so that the compost film is evenly spread on the compost pile. During the film winding operation, the second driving motor 130 rotates in the reverse direction to wind up and store the compost film. During the whole process, the PLC controller coordinates the rotation speeds of the two first driving motors 250 and the second driving motor 130 to ensure the flat covering and winding of the compost film and avoid wrinkles or tears in the compost film.
