Description

Technical Field

[0001] This invention belongs to the field of food industrial processing technology, specifically a roller conveyor based on logistics transfer. Background Technology

[0002] Roller conveyors are general-purpose equipment that uses the rotation of rollers to transport unitized goods. Their core is a series of rollers arranged in parallel. The goods are moved smoothly by gravity or external force. They have a simple and reliable structure and are easy to maintain, so they are commonly used in the logistics field.

[0003] Roller conveyors are core equipment for the automation of food industry production lines, running through the entire process from raw materials to finished products. They are responsible for efficiently connecting various process links, such as food raw material sorting, cleaning, processing, sterilization and cooling, and finished product packaging. Their core advantages are improving efficiency, reducing labor, and reducing product damage.

[0004] Traditional roller conveyors have relatively simple functions. In terms of controlling the emergency stop of food goods, they often only use fixed baffles and power-stopping methods to stop the food goods. In this case, not only is it highly limited, as it can only stop the food goods from the end, but the food goods are also prone to continue moving forward under the action of inertia, which shortens the originally designed gap between the food goods. This not only affects the subsequent sorting process, but also easily causes collisions and other damage to the food goods.

[0005] Therefore, the present invention provides a roller conveyor based on logistics transfer. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a roller conveyor based on logistics transfer, including a support frame, two side frames fixed to the top of the support frame, a plurality of transport rollers arranged at equal intervals between the two side frames, a power box for driving the transport rollers fixed to the bottom of one of the side frames, the interior of the transport rollers being hollow, a plurality of air holes being opened on the surface of the transport rollers, a pneumatic module being connected to the outer side of one of the side frames, and a laser module for detecting the logistics position being provided on the opposite side of the two side frames;

[0008] With this setup, even with multiple emergency stops, the gaps between food items can always remain in their initial state. Furthermore, it eliminates the need for low-speed transport of food items, allowing for safe emergency stops even at high speeds. Additionally, because each transport roller has air vents, the food items can be stopped instantly regardless of their position, maintaining their original location. Moreover, in logistics transportation, the inertial sliding and collisions caused by stopping large food items can easily lead to safety hazards such as injuries from being pinched. This pneumatic stopping method significantly reduces these safety risks and improves the safety of the equipment.

[0009] Preferably, the side frame has a protective groove on the side facing the transport roller, the end of the transport roller is located in the protective groove, and both ends of the transport roller are fixedly connected to a cylinder communicating with the inside of the transport roller. The outer side of the cylinder is rotatably engaged with the side frame. One of the side frames has a transmission groove, and the cylinder communicates with the transmission groove. Both ends of the transport roller are rotatably engaged with the side frame to form a horizontal support. At the same time, the cylinder at the end communicates with the transmission groove to facilitate the transmission of air pressure. When air pressure needs to be transmitted, air pressure is injected into the transmission groove, and the cylinder that does not need air pressure is closed, so that all other transport rollers can synchronously spray airflow outward to complete the function of emergency stop of food goods.

[0010] Preferably, a stripping platform for removing debris from the surface of the transport roller is provided below the transport roller. A connecting frame is fixed between the bottoms of the two support frames, and the stripping platform is located on top of the connecting frame. The stripping platform includes a movable scraper table, and long blades are installed at both ends of the top of the scraper table. During the transportation of food goods, easily entangled waste materials such as detached adhesive tape often occur. Traditional roller conveyors are easily entangled by these waste materials, causing the transport line to stop. Subsequent cleaning can only be done manually, which also affects work efficiency. It is possible to keep the transmission trough at a certain amount of air pressure, keeping multiple air holes in a continuous air jet state, but the air pressure is relatively small. It will not affect the normal transportation of food goods, but easily entangled waste is difficult to adhere to the transport rollers, thus greatly reducing the risk of entanglement. If it is still caught on the outside of the transport rollers, the scraper table located below the transport rollers will keep the long blades at its ends in reverse against the outside of the transport rollers. This can scrape off the foreign matter before it gets entangled, preventing it from getting entangled on the outside of the transport rollers and causing it to fall off from the bottom. The scraper table has long blades at both ends, which can move itself when the transport rollers change their rotation direction, ensuring that the different long blades always adhere to the transport rollers in reverse, thus ensuring the scraping effect. A negative pressure adsorption system can be installed at the bottom of the support frame to assist in the recycling of waste.

[0011] Preferably, the scraper platform is made of an elastic material, and elastic side arms are fixed to both ends of the top of the scraper platform. The long blade is connected to the end of the side arms. A detection groove penetrating both sides is opened in the middle of the scraper platform. Combined with the elastic material of the scraper platform and side arms, when the long blade contacts the transport roller, it deforms to apply adaptive pressure to the blade, ensuring that the blade presses against the surface of the transport roller and has sufficient force to scrape away foreign objects. When foreign objects are detected, the air pressure of the transport roller can be increased separately to push the foreign objects outwards, even for sticky foreign objects such as tape. This allows the ends to be lifted upwards, enabling the long blades to scrape away the foreign matter more effectively. Then, in conjunction with the negative pressure adsorption system below, the foreign matter is recovered. The detection method involves adding a laser module to the transport roller. As the scraper platform bends, the detection groove in the middle will face vertically upwards. The detection groove contains a receiving module. When the laser emitted by the upper transport roller is blocked by a foreign object, the receiving module cannot receive the signal, thereby controlling the corresponding transport roller's air pressure to increase. This also controls the entire scraper platform to fit more closely to the transport roller, increasing the force of the long blades squeezing the transport roller and further ensuring the effective removal of foreign matter.

[0012] Preferably, a fixed platform is fixedly connected to the bottom of the scraper table, and multiple vertically arranged electric telescopic rods are fixedly connected to the bottom of the fixed platform. A translation box is fixedly connected to the bottom of the electric telescopic rods, and the moving end of the translation box is fixedly connected to the connecting frame. The scraper table is raised and lowered by driving the electric telescopic rods. The translation box pushes the connecting frame in the opposite direction, thereby moving the translation box and completing the translation of the scraper table, thus realizing the function of controlling the adjustment of the scraper table position.

[0013] Preferably, the transport roller is composed of multiple unit rings, and the air holes are divided into two groups on the surface of the unit rings. The multiple air holes in each group are arranged in a ring at equal intervals, and the air holes in different groups face different directions. The transport roller is provided with multiple sealing rings for sealing the air holes. The air jets from the air holes with different directions have completely different effects on blocking the movement of food goods. The angle between the air flow and the food goods is close to 90 degrees. The stronger the effect of the air flow in lifting the food goods, the more effective the two groups of air holes with different directions are in the rotation of the transport roller. When one group is in use, the other group of air holes is sealed by the movable sealing rings to ensure that the limited air pressure blocks the movement of food goods to the greatest extent.

[0014] Preferably, the multiple sealing rings are arranged linearly at equal intervals. A series frame is provided inside the transport roller, and a central rod is fixedly connected to the center of the series frame. A light emitting module is fixedly connected to the bottom surface of the sealing ring. By moving the central rod at the end, the multiple sealing rings are controlled to translate. The sealing rings do not rotate synchronously with the transport roller and always remain stationary. When one set of air holes is blocked, the light emitting module on the bottom surface of the sealing ring is activated. At this time, the laser emitted by the set of air holes is matched with the detection module in the detection slot to detect whether there are foreign objects on the outside of the transport roller.

[0015] Preferably, one end of the central rod is located on the outside of the cylinder. One of the side frames is fixedly connected to a plurality of sealing valves for sealing the cylinder, and the other side frame is fixedly connected to a plurality of driving components adapted to the end of the central rod. The sealing valve has a movable sealing end. By bringing the sealing end close to or against the cylinder, the magnitude of the air pressure transmission can be controlled or the air pressure transmission can be directly blocked to ensure that the air pressure can be smoothly delivered to the required transport roller. The driving component can be a hydraulic rod to control the sealing state of the sealing ring.

[0016] Preferably, a connecting platform is fixedly connected to the end of the side arm, and the long blade is connected to the connecting platform. The bottom of the long blade has multiple cutting grooves, and the end of the connecting platform has multiple spray holes adapted to the cutting grooves. The long blade and the connecting platform are locked together for easy replacement of the long blade. In order to increase the effect of scraping foreign objects, the air pressure can be connected to the scraper platform. During the scraping process, the air pressure is sprayed out from the spray holes to make the end of the foreign object lift outward, assisting the scraping process of the long blade.

[0017] Preferably, the outer sides of both ends of the conveying roller are provided with inner grooves, and a horizontally arranged power shaft is installed in the power box. The inner grooves of the conveying roller are connected to the power shaft by a flexible transmission belt. Through the flexible transmission connection between the power shaft and the conveying roller, the start and stop of multiple conveying rollers can be controlled synchronously.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention discloses a roller conveyor based on logistics transfer. By opening the transport rollers and air holes, when the conveyor needs to stop urgently, the power of the power box is shut off, and air pressure is simultaneously supplied to multiple transport rollers. Specifically, the transport rollers between two food items can be located by laser detection. The airflow ejected from the air holes of the transport rollers between two food items can form an air wall, which can effectively counteract the forward momentum of the food items and the resistance is relatively uniform, which can ensure the safety of the food items and prevent the problem of mutual expansion between food items. At the same time, after stopping, a certain amount of gap is still maintained between each food item, so as to maintain an orderly transportation process after merging and facilitate the final sorting process.

[0020] 2. The roller conveyor based on logistics transfer described in this invention, in order to further ensure the collective effect of food goods, can synchronously deliver air pressure to the conveyor rollers where the front end of the food goods is pressed. At this time, with the output of air pressure, the end of the food goods will be lifted upward by a small height. At this time, the forward power is transformed into an upward lifting force, which better consumes the inertia of forward movement. Then, the lifted food goods are pressed down under the action of gravity. As the air pressure gradually decreases, the food goods eventually return smoothly. With this setting, even if multiple emergency stops occur, the gap between the food goods can always maintain its initial state. At the same time, it does not require low-speed transportation of food goods. It can maintain a safe emergency stop process between food goods even when the equipment is in high-speed transportation. In addition, since each conveyor roller has air holes, the food goods can complete the emergency stop operation and maintain their original position regardless of their position. Moreover, in logistics transportation, the inertial sliding and collision caused by the stopping of large food goods can easily cause safety hazards such as personnel pinching. This pneumatic stopping method of the equipment can also greatly reduce safety hazards and improve the safety of equipment use. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 8 As shown in the embodiment of the present invention, a roller conveyor based on logistics transfer includes a support frame 1. Two side frames 6 are fixedly connected to the top of the support frame 1. Multiple transport rollers 2 are installed between the two side frames 6 at equal intervals. A power box 3 for driving the transport roller 2 is fixedly connected to the bottom of one of the side frames 6. The interior of the transport roller 2 is hollow. Multiple air holes 9 are opened on the surface of the transport roller 2. A pneumatic module is connected to the outside of one of the side frames 6. A laser module for detecting the logistics position is provided on the opposite side of the two side frames 6.

[0033] Multiple transport rollers 2 are driven to rotate in the same direction by a power unit 3, thereby transporting the logistics food goods located above in a designated direction. During transportation, one of the laser modules on the two side frames 6 emits a laser, and the other receives it. When the laser is blocked by the food goods, it indicates that the food goods have been transported to this point, thus determining the transportation status of the food goods. Since the transportation of logistics food goods requires the cooperation of multiple conveyors to complete the movement, turning, lifting, and other transportation methods of the food goods, an emergency stop function for the food goods needs to be set up to ensure the smooth operation of the overall transportation process with multiple conveyors interconnected. When transport vehicles merge at their ends, if both ends contain food goods, multiple transport vehicles need to transfer the food goods one by one to the merging transport vehicle. The other transport vehicles need to temporarily stop transporting. However, food goods in logistics transfers are often heavy, and to ensure transport efficiency, the transport speed is generally high. If there is a height difference at the merging point, a stronger stopping function is required. If only baffles are installed at the ends of each transport vehicle in conjunction with the stopping of the transport vehicles, the food goods will not only slide forward due to inertia, causing them to accumulate in front of the baffles, but when transport is needed again, the gaps between the food goods will be compressed. The shrinkage of the conveyor rollers (2) and air vents (9) makes it impossible to locate food items using the laser system during subsequent transport. The lack of gaps also hinders sorting and transfer processes. Furthermore, traditional logistics transportation requires multiple emergency stops, which further compresses the gaps between food items, causing them to merge and severely impact subsequent processes. Additionally, the inertia of the conveyor increases the risk of chain-reaction collisions, especially for fragile items like LCD screens or puffed foods, which are easily damaged by repeated impacts. The design of the conveyor rollers (2) and air vents (9) allows the power unit (3) to be shut down when the conveyor needs to be stopped urgently. The power simultaneously delivers air pressure to multiple transport rollers 2. The specific location of the transport rollers 2 between two food items can be determined by laser detection. The airflow ejected from the air holes 9 of the transport rollers 2 between two food items can form an air wall, which can effectively counteract the forward momentum of the food items and the resistance is relatively uniform, ensuring the safety of the food items and preventing the problem of mutual expansion between food items. At the same time, it can maintain a certain gap between each food item after stopping, so as to maintain an orderly transportation process after merging and facilitate the final sorting process.To further ensure the overall effectiveness of the food goods, air pressure can be synchronously supplied to the conveyor rollers 2 that press the front ends of the food goods. As the air pressure is output, the ends of the food goods are lifted slightly upwards. The forward momentum is then converted into an upward lifting force, better consuming the inertia of forward movement. The lifted food goods are then pressed down under gravity. As the air pressure gradually decreases, the food goods eventually return smoothly to their original position. With this setup, even with multiple emergency stops, the gaps between the food goods remain at their initial state. Furthermore, low-speed transport of the food goods is not required; a safe emergency stop process can be maintained even at high speeds. Additionally, since each conveyor roller 2 has air holes 9, the food goods can complete an emergency stop operation regardless of their position, while maintaining their original position. Moreover, in logistics transportation, the inertial sliding and collisions caused by stopping large food goods can easily lead to safety hazards such as injuries from being pinched. This pneumatic stopping method significantly reduces these safety hazards and improves the safety of the equipment.

[0034] The side frame 6 has a protective groove on the side facing the transport roller 2. The end of the transport roller 2 is located in the protective groove, and both ends of the transport roller 2 are fixedly connected to a cylinder 16 that communicates with the inside of the transport roller 2. The outer side of the cylinder 16 is rotatably engaged with the side frame 6. One of the side frames 6 has a transmission groove 7, and the cylinder 16 communicates with the transmission groove 7.

[0035] During operation, both ends of the conveyor roller 2 are rotated and clamped onto the side frame 6 to form a horizontal support. At the same time, the cylinder 16 at the end is connected to the transmission groove 7 to facilitate the transmission of air pressure. When air pressure needs to be transmitted, air pressure is injected into the transmission groove 7, and the cylinder 16 that does not need to be injected with air pressure is closed. This allows all the other conveyor rollers 2 to spray air outward synchronously, thus completing the function of emergency stop of food goods.

[0036] Below the transport roller 2, there is a stripping table 5 for stripping debris from the surface of the transport roller 2. A connecting frame 4 is fixed between the bottoms of the two support frames 1. The stripping table 5 is located on top of the connecting frame 4. The stripping table 5 includes a movable scraper table 13. Long blades 23 are installed at both ends of the top of the scraper table 13.

[0037] During food transport, easily entangled waste materials such as detached adhesive tape often occur. Traditional roller conveyors are easily entangled by these materials, causing transport line shutdowns and requiring manual cleaning, which also affects work efficiency. A method that maintains a certain amount of air pressure in the transmission trough 7, keeping multiple air holes 9 constantly spraying air, can effectively prevent easily entangled waste materials from adhering to the transport rollers 2, thus greatly reducing the risk of entanglement. However, if the waste materials are still caught in the transport rollers 2... On the outside, the scraper platform 13 located below the conveyor roller 2 always keeps the long strip blades 23 at its ends in reverse contact with the outside of the conveyor roller 2. This can scrape off foreign objects before they wrap around the outside of the conveyor roller 2, preventing them from wrapping around and causing them to fall off from the bottom. Both ends of the scraper platform 13 have long strip blades 23. When the conveyor roller 2 changes its rotation direction, the scraper platform 13 can move itself to keep the different long strip blades 23 in reverse contact with the conveyor roller 2, ensuring the scraping effect. A negative pressure adsorption system can be set at the bottom of the support frame 1 to assist in the recycling of waste materials.

[0038] The scraper table 13 is made of elastic material. Both ends of the top of the scraper table 13 are fixed with elastic material side arms 22. The long blade 23 is connected to the end of the side arm 22. The middle of the scraper table 13 is provided with a detection groove 21 that runs through both sides.

[0039] During operation, the elastic material of the scraper table 13 and side arm 22 allows the long blade 23 to deform and apply adaptive pressure to the conveyor roller 2 when it contacts the roller 2. This ensures that the long blade 23 is pressed against the surface of the conveyor roller 2 and has sufficient force to scrape away foreign objects. When foreign objects are detected, the air pressure of the conveyor roller 2 can be increased separately to push the foreign objects outwards. Even sticky foreign objects such as tape can have their ends pushed upwards, allowing the long blade 23 to scrape them off more effectively. Then, in conjunction with the negative pressure below… The pressure adsorption system recovers foreign objects; the detection method can be achieved by adding a laser module to the transport roller 2. As the scraper table 13 bends, the detection groove 21 in the middle will face vertically upward. The detection groove 21 is equipped with a receiving module. When the laser emitted by the upper transport roller 2 is blocked by foreign objects, the receiving module cannot receive the signal, thereby controlling the corresponding air pressure of the transport roller 2 to increase. It can also control the entire scraper table 13 to fit more closely to the transport roller 2, increasing the pressure of the long blade 23 on the transport roller 2, and further ensuring the peeling effect of foreign objects.

[0040] The bottom of the scraper table 13 is fixedly connected to a fixed platform 20, and the bottom of the fixed platform 20 is fixedly connected to a plurality of vertically arranged electric telescopic rods 12. The bottom of the electric telescopic rods 12 is fixedly connected to a translation box 11, and the moving end of the translation box 11 is fixedly connected to the connecting frame 4.

[0041] During operation, the scraper table 13 is raised and lowered by the electric telescopic rod 12. The translation box 11 pushes the connecting frame 4, thereby moving the translation box 11 and completing the translation of the scraper table 13, thus realizing the function of controlling the adjustment of the position of the scraper table 13.

[0042] The transport roller 2 is composed of multiple unit rings 14. The air holes 9 are divided into two groups on the surface of the unit rings 14. The multiple air holes 9 in each group are arranged in a ring at equal intervals, and the air holes 9 in different groups face different directions. The transport roller 2 is provided with multiple sealing rings 19 for sealing the air holes 9.

[0043] During operation, the airflow ejected from the air holes 9 in different directions has completely different effects on blocking the movement of food goods. The angle between the airflow and the food goods is close to 90 degrees. The stronger the effect of the airflow in lifting the food goods, the more effective the two sets of air holes 9 in different directions are. They correspond to the two different directions of rotation of the transport roller 2. When using one set, the other set of air holes 9 is blocked by the movable sealing ring 19 to ensure that the limited air pressure blocks the movement of food goods to the greatest extent.

[0044] Multiple sealing rings 19 are arranged linearly at equal intervals. A series frame 18 is provided inside the transport roller 2. A central rod 17 is fixedly connected to the center of the series frame 18. A light emitting module is fixedly connected to the bottom surface of the sealing ring 19.

[0045] During operation, by moving the center rod 17 at the end, multiple sealing rings 19 are controlled to translate. The sealing rings 19 do not rotate synchronously with the transport roller 2 and always remain stationary. When one set of air holes 9 is blocked, the light emitting module on the bottom surface of the sealing ring 19 is turned on. At this time, the laser emitted by the set of air holes 9 is matched with the detection module in the detection groove 21 to detect whether there are foreign objects on the outside of the transport roller 2.

[0046] One end of the central rod 17 is located on the outside of the cylinder 16. One of the side frames 6 is fixedly connected with a plurality of sealing valves 8 for sealing the cylinder 16, and the other side frame 6 is fixedly connected with a plurality of driving components adapted to the end of the central rod 17.

[0047] During operation, the sealing valve 8 has a movable sealing end. By bringing the sealing end close to or abutting the cylinder 16, the magnitude of air pressure transmission can be controlled or the air pressure transmission can be directly blocked to ensure that the air pressure can be smoothly delivered to the required transport roller 2. The driving component can be a hydraulic rod, which is used to control the sealing state of the sealing ring 19.

[0048] The end of the side arm 22 is fixedly connected to a connecting platform 24, the long blade 23 is connected to the connecting platform 24, the bottom of the long blade 23 is provided with multiple cutting grooves 26, and the end of the connecting platform 24 is provided with multiple spray holes 25 that are adapted to the cutting grooves 26.

[0049] During operation, the long blade 23 is locked to the connecting platform 24, which facilitates the replacement of the long blade 23. In order to increase the scraping effect of foreign objects, the air pressure can be connected to the scraper platform 13. During the scraping process, the air pressure is sprayed out from the spray hole 25 to make the end of the foreign object lift outward, which assists the scraping process of the long blade 23.

[0050] The outer sides of both ends of the conveying roller 2 are provided with inner grooves, and a horizontally arranged power shaft 10 is installed in the power box 3. The inner grooves of the conveying roller 2 and the power shaft 10 are connected by a flexible transmission belt.

[0051] During operation, the start and stop of multiple transport rollers 2 can be controlled synchronously through the flexible transmission connection between the power shaft 10 and the transport rollers 2.

[0052] During operation, the power unit 3 drives multiple transport rollers 2 to rotate in the same direction, thereby transporting the food goods located above in the designated direction. During transportation, one of the laser modules on the two side frames 6 emits a laser, and the other receives it. When the laser is blocked by the food goods, it indicates that the food goods have been transported to this point, thus determining the transportation status of the food goods. Since the transportation of food goods requires the cooperation of multiple conveyors to complete the movement, turning, lifting, and other transportation methods of the food goods, an emergency stop function for the food goods needs to be set up to ensure the smooth operation of the overall transportation process with multiple conveyors interconnected. Yes; through the arrangement of the transport rollers 2 and air holes 9, when the conveyor needs to stop urgently, the power of the power box 3 is shut off, and air pressure is simultaneously supplied to multiple transport rollers 2. Specifically, the transport rollers 2 between two food items can be located using laser detection. The airflow ejected from the air holes 9 from the transport rollers 2 between two food items can form an air wall, effectively counteracting the forward momentum of the food items with relatively uniform resistance, ensuring the safety of the food items, and preventing the problem of mutual expansion between food items. Furthermore, it ensures that after stopping, each food item maintains a certain distance from the others. The precise spacing ensures an orderly transport process after merging, facilitating final sorting. To further guarantee the overall quality of the food goods, air pressure is synchronously supplied to the transport roller 2, which presses the front end of the food goods. As the air pressure is output, it lifts the end of the food goods slightly, converting the forward momentum into an upward lifting force, better absorbing the inertia of forward movement. The lifted food goods then press down under gravity, and as the air pressure gradually decreases, the food goods eventually return smoothly to their original position. This setup prevents multiple sudden movements from causing problems. The pneumatic stopping mechanism ensures that the gaps between food items remain at their initial state, eliminating the need for low-speed transport. It allows for safe emergency stops even during high-speed transport. Furthermore, the presence of air holes 9 on each transport roller allows for emergency stops regardless of the food items' position, maintaining their original location. In logistics transportation, the inertial sliding and collisions caused by stopping large food items can easily lead to injuries such as pinching. This pneumatic stopping method significantly reduces these safety hazards and improves equipment safety.

[0053] Both ends of the conveyor roller 2 are rotatably clamped onto the side frame 6 to form a horizontal support. At the same time, the cylinder 16 at the end is connected to the transmission groove 7 to facilitate the transmission of air pressure. When air pressure needs to be transmitted, air pressure is injected into the transmission groove 7, and the cylinder 16 that does not need to be injected with air pressure is closed. This allows all the other conveyor rollers 2 to spray air outward synchronously, thus completing the function of emergency stop of food goods.

[0054] During food transport, easily entangled waste materials such as detached adhesive tape often occur. Traditional roller conveyors are easily entangled by these materials, causing transport line shutdowns and requiring manual cleaning, which also affects work efficiency. A method that maintains a certain amount of air pressure in the transmission trough 7, keeping multiple air holes 9 constantly spraying air, can effectively prevent easily entangled waste materials from adhering to the transport rollers 2, thus greatly reducing the risk of entanglement. However, if the waste materials are still caught on the outside of the transport rollers 2... The scraper platform 13 located below the conveyor roller 2 always keeps the long strip blades 23 at its ends in reverse contact with the outside of the conveyor roller 2. This can scrape off foreign objects before they wrap around the outside of the conveyor roller 2, preventing them from wrapping around and causing them to fall off from the bottom. The scraper platform 13 has long strip blades 23 at both ends. When the conveyor roller 2 changes its rotation direction, it can move itself to keep the different long strip blades 23 in reverse contact with the conveyor roller 2, ensuring the scraping effect. A negative pressure adsorption system can be set at the bottom of the support frame 1 to assist in the recycling of waste materials.

[0055] The elastic material of the scraper table 13 and side arm 22 allows the long blade 23 to deform and apply adaptive pressure to the conveyor roller 2 when it contacts the roller 2, ensuring that the blade 23 is pressed against the surface of the roller 2 and has sufficient force to scrape away foreign objects. When foreign objects are detected, the air pressure of the conveyor roller 2 can be increased separately to push the foreign objects outwards. Even sticky foreign objects such as tape can have their ends pushed upwards, allowing the blade 23 to scrape them off more effectively. This is then combined with the negative pressure suction below... The system is equipped to recover foreign objects. The detection method can be achieved by adding a laser module to the transport roller 2. As the scraper table 13 bends, the detection groove 21 in the middle will face vertically upward. The detection groove 21 is equipped with a receiving module. When the laser emitted by the upper transport roller 2 is blocked by foreign objects, the receiving module cannot receive the signal, thereby controlling the corresponding air pressure of the transport roller 2 to increase. It can also control the entire scraper table 13 to fit more closely to the transport roller 2, increase the pressure of the long blade 23 on the transport roller 2, and further ensure the peeling effect of foreign objects.

[0056] Driven by the electric telescopic rod 12, the scraper table 13 is raised and lowered. The translation box 11 pushes the connecting frame 4, thereby moving the translation box 11 and completing the translation of the scraper table 13, thus realizing the function of controlling the adjustment of the position of the scraper table 13.

[0057] The airflow ejected from the vents 9 in different directions has completely different effects on blocking the movement of food goods. The angle between the airflow and the food goods is close to 90 degrees. The stronger the effect of the airflow in lifting the food goods, the more effective the two sets of vents 9 in different directions are. They correspond to the two different directions of rotation of the transport roller 2. When using one set, the other set of vents 9 is blocked by the movable sealing ring 19 to ensure that the limited air pressure blocks the movement of food goods to the greatest extent.

[0058] By moving the center rod 17 at the end, multiple sealing rings 19 are controlled to translate. The sealing rings 19 do not rotate synchronously with the transport roller 2 and always remain stationary. When one set of air holes 9 is blocked, the light emitting module on the bottom surface of the sealing ring 19 is turned on. At this time, the laser emitted by the set of air holes 9 is matched with the detection module in the detection groove 21 to detect whether there are foreign objects on the outside of the transport roller 2.

[0059] The sealing valve 8 has a movable sealing end. By bringing the sealing end close to or abutting the cylinder 16, the magnitude of air pressure transmission can be controlled or the air pressure transmission can be directly blocked to ensure that the air pressure can be smoothly delivered to the required transport roller 2. The driving component can be a hydraulic rod, which is used to control the sealing state of the sealing ring 19.

[0060] The long blade 23 is fixed to the connecting platform 24 by interlocking, which makes it easy to replace the long blade 23. In order to increase the effect of scraping foreign objects, the air pressure can be connected to the scraper platform 13. During the scraping process, the air pressure is sprayed out from the spray hole 25 to make the end of the foreign object flip outward, which assists the scraping process of the long blade 23.

[0061] The start and stop of multiple transport rollers 2 can be controlled synchronously through the flexible transmission connection between the power shaft 10 and the transport rollers 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
