A waste recycling device for FIBC (Flexible Intermediate Bulk Container) processing

Abstract

This invention discloses a waste recycling device for FIBC (Flexible Intermediate Bulk Container) processing, relating to the field of comprehensive environmental utilization of solid waste. The device includes a hollow frame, a hydraulic rod mounted on the hollow frame, and a pressure plate mounted on the hydraulic rod. The equipment continuously feeds FIBC waste into a flattening machine. The pressure plate is automatically triggered by the weight of the waste, achieving a complete automatic cycle of feeding, weighting, triggering, compaction, resetting, and locking, thus improving waste recycling efficiency. When not in operation, the pressure plate is rigidly limited by a limiting mechanism, preventing hydraulic system depressurization or accidental drop. This ensures uniform compaction density of the plastic waste, reducing the mixing and adhesion of plastic and impurities due to insufficient compaction, facilitating subsequent separation of plastic from other components. It also protects core components such as the hydraulic rod and pressure plate, extending equipment lifespan, reducing maintenance costs, and contributing to the resource-based recycling of plastic waste and comprehensive utilization of solid waste.

Description

Technical Field

[0001] This invention relates to the field of environmentally friendly comprehensive utilization technology of solid waste, specifically to a waste recycling device for FIBC processing. Background Technology

[0002] The comprehensive environmental utilization of solid waste involves the process of compressing, sorting, and pre-treating solid materials from production and daily life to transform them back into raw materials or energy sources, while simultaneously controlling pollution and reducing environmental risks. FIBCs (Flexible Intermediate Bulk Containers), a commonly used flexible transport packaging container, are mostly made of plastics such as polypropylene and polyethylene. During the cutting, sewing, and forming processes, a large amount of plastic scraps and discarded bags are generated. Improper handling not only occupies significant production space and increases transportation and storage costs, but also hinders the subsequent recycling of other components from the plastic waste, failing to meet environmental protection and comprehensive solid waste utilization requirements and impeding resource recycling.

[0003] Currently, existing technologies for recycling and processing waste from FIBC (Flexible Intermediate Bulk Container) processing mostly rely on simple compaction equipment or manual processing methods, which still have many shortcomings and cannot meet the environmental protection recycling and resource recycling needs of large-scale production.

[0004] The technical solution with patent number CN216860288U involves placing plastic bottle waste onto the surface of a moving plate. A first motor operates, causing a third rotating shaft to rotate the moving plate and a limiting plate, moving the plastic bottle waste into the working box. Then, a first hydraulic pump operates, causing a first hydraulic rod to move a pressure plate, flattening the plastic bottle waste inside the working box. This significantly reduces the workload of workers and improves the efficiency of plastic bottle waste recycling.

[0005] The above-mentioned technical solutions have obvious limitations in practice: existing technologies cannot adaptively adjust according to the amount of waste accumulation, which can easily lead to wasted energy consumption due to air pressure and insufficient compaction affecting subsequent recycling. Furthermore, the pressure plate lacks reliable mechanical limit protection, which can easily lead to accidental falling due to hydraulic depressurization or false triggering, posing serious safety hazards. At the same time, resetting and locking require repeated manual operation, which is cumbersome and prone to safety accidents due to human negligence. The safety hazards are significant, the recycling efficiency is insufficient, and it is difficult to adapt to the needs of environmental protection and resource recycling. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a waste recycling device for FIBC processing, which solves the problems mentioned in the background technology, such as the inability to achieve adaptive compaction triggered by waste weight, the need for manual intervention and control, the mismatch between feeding and compaction rhythms, the easy jamming and blockage of materials, the significant reduction in processing efficiency, the loss of limit protection of the pressure plate, the easy accidental fall causing safety hazards, and the need for repeated manual reset and locking, which is cumbersome and prone to negligence.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste recycling device for FIBC processing, comprising a hollow frame, a hydraulic rod mounted on the hollow frame, and a pressure plate mounted on the hydraulic rod. The waste recycling device further comprises a compaction mechanism mounted on the hollow frame for compacting the waste material. The compaction mechanism includes a sliding groove frame mounted on the hollow frame, a rack slidably mounted within the sliding groove frame, a top rod slidably mounted on the rack, a slotted frame mounted on the pressure plate, a positioning frame mounted on the hollow frame, a sliding rod slidably mounted within the positioning frame, a positioning block mounted on the sliding rod, and an inclined groove block mounted on the sliding rod. The contact surface between the positioning block and the slotted frame is set as an inclined surface. A first spring is provided between the positioning block and the positioning frame, and the first spring drives the positioning block to reset.

[0008] According to the above technical solution, the compaction mechanism further includes a motor mounted on the hollow frame and a hydraulic unit mounted on the hollow frame; the hydraulic unit is connected to the motor; the hydraulic unit is connected to the hydraulic rod.

[0009] In the above embodiment, after the waste material in the container bag is put into the hollow frame, the motor rotates, and the hydraulic oil is sent to the hydraulic rod through the hydraulic unit, which drives the pressure plate to compact the waste material in the container bag. Before the pressure plate works, its displacement is restricted by the positioning block.

[0010] According to the above technical solution, the compaction mechanism further includes a reciprocating screw rod rotatably installed in the rack rod, a gravity plate slidably installed in the hollow frame, a gear installed on the hollow frame, a slider installed on the gravity plate, and a drive rack installed on the slider; the inner wall of the top rod is provided with a groove matching the reciprocating screw rod; a second spring is provided between the gravity plate and the hollow frame, and the gravity plate is driven to return to its original position by the second spring; the gear meshes with the drive rack; the gear meshes with the rack rod.

[0011] In the above embodiment, the gravity plate moves downward and simultaneously drives the slider to move. The slider's movement drives the drive rack to move, which in turn causes the gear to rotate. The gear's rotation causes the rack on one side to move upward along the slide frame. A push rod is installed on the rack, so that after reaching a certain distance, it contacts the inclined surface of the inclined block, causing the inclined block to move to the right under force. The movement of the inclined block drives the slide rod to move, which in turn drives the positioning block to move, causing it to disengage from the slot frame and simultaneously compress the first spring. At this time, the pressure plate is released from its restraint.

[0012] According to the above technical solution, the waste recycling device for FIBC processing also includes a cleanup mechanism and a pretreatment mechanism; the cleanup mechanism is installed on the hollow frame and is used to seal the compaction mechanism during operation and to push out the compressed material after the compaction mechanism has finished working; the pretreatment mechanism is installed on the hollow frame and is used to perform preliminary compaction pretreatment on the FIBC before it enters the compaction mechanism.

[0013] According to the above technical solution, the recovery mechanism includes a cover plate rotatably mounted on a hollow frame, a locking groove mounted on the cover plate, a mounting plate mounted on the hollow frame, a rotating rod rotatably mounted in the mounting plate, a locking rod mounted on the rotating rod, an unlocking wheel mounted on the rotating rod, and an L-shaped gear mounted on a gravity plate; a first torsion spring is provided between the cover plate and the hollow frame, which drives the cover plate to reset; a second torsion spring is provided between the rotating rod and the mounting plate, which drives the rotating rod to reset; the unlocking wheel meshes with the L-shaped gear.

[0014] In the above embodiment, the movement of the cover plate causes the locking groove to move. After the locking groove passes through the locking rod, the manual adjustment of the rotating rod along the mounting plate causes the locking rod to restrict the reset path of the locking groove.

[0015] According to the above technical solution, the aftermath mechanism also includes an electric push rod installed on the hollow frame, a push plate installed on the electric push rod, and a connecting rod installed on the cover plate.

[0016] In the above embodiments, after compaction is completed, the compressed block is automatically pushed out by an electric push rod driving the push plate.

[0017] According to the above technical solution, the pretreatment mechanism includes a placement plate installed on a hollow frame, a second motor installed on the hollow frame, and a sliding button installed on the output end of the second motor.

[0018] According to the above technical solution, the pretreatment mechanism further includes a sliding frame slidably installed in the placement plate, a transfer ring sleeved in the sliding frame, and a connecting rope for connecting the cover plate and the sliding frame; a No. 3 spring is provided between the sliding frame and the placement plate, and the sliding frame is reset by the No. 3 spring; the transfer ring is in contact with the sliding groove button.

[0019] According to the above technical solution, the pretreatment mechanism further includes a pre-pressure roller rotatably mounted on the placement plate and a receiving ring mounted on the pre-pressure roller; both the receiving ring and the transfer ring are provided with inclined grooves, and the inclined grooves of the receiving ring and the transfer ring are matched with each other.

[0020] In the above embodiments, the motor 2 engages with the preload roller for transmission only after the cover plate is closed and sealed; when the cover plate is opened, the power is automatically cut off and the preload roller stops rotating.

[0021] According to the above technical solution, the pretreatment mechanism further includes a connecting frame mounted on the placement plate, an eccentric rod rotatably mounted in the connecting frame, an undulating rod slidably mounted on the placement plate, a pre-pressing plate mounted on the undulating rod, and a connecting rod for connecting the eccentric rod and the undulating rod; the eccentric rod and the pre-pressing roller are connected by a belt for transmission.

[0022] In the above embodiment, the rotation of the pre-compression roller is transmitted to the eccentric rod via a belt, causing the eccentric rod to rotate along the connecting frame and drive the connecting rod to rotate. The rotation of the connecting rod drives the undulating rod to move up and down along the placement plate. The movement of the placement plate drives the pre-compression plate to move synchronously, thus compacting the rear end of the waste material in the container bag.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the device significantly reduces the volume of plastic waste from bulk bags by compacting the waste material, thereby reducing the pollution caused by the scattering of waste during transportation, meeting environmental protection requirements, and avoiding the environmental burden caused by the indiscriminate disposal of plastic waste. The equipment can continuously feed bulk bag waste into the flattening machine, and the pressure plate is automatically triggered by the gravity of the waste material itself. The equipment has high operational safety and strong stability. When the pressure plate is not in operation, it is rigidly limited by the limiting mechanism, which can prevent the pressure plate from falling accidentally due to hydraulic system depressurization or misoperation, thus avoiding equipment damage and safety hazards. The compacted plastic waste has uniform density and stable molding, which facilitates the subsequent separation and reprocessing of plastic components, realizes the recycling of plastic resources, improves the comprehensive utilization efficiency of solid waste, and reduces resource waste.

[0024] 2. In this invention, mechanical locking is achieved after the cover is closed, which can prevent the plastic waste in the container bag from rebounding and expanding due to pressure and opening the cover during the compaction operation, avoiding waste splashing, jamming, or injury, and significantly improving the safety of equipment operation. After locking, the compaction chamber forms a closed space, and the pressure of the pressure plate is completely applied to the inside of the waste, resulting in higher compaction density and more stable molding effect, reducing loose rebound, facilitating the subsequent transfer, separation and reuse of plastic waste, and contributing to resource recycling. The automatic and manual dual unlocking methods serve as backups to avoid the failure of a single unlocking method leading to equipment malfunction, improving the reliability of the whole machine and continuous operation capability. After compaction, the push plate is automatically pushed out by the electric push rod, replacing manual material handling and reducing manual intervention, labor intensity and safety risks.

[0025] 3. In this invention, the loose plastic waste in the container bag can be continuously rolled by the symmetrical pre-compression rollers to expel internal air and reduce volume and thickness. The reciprocating motion of the pre-compression plate can continuously beat and assist in compaction of the material at the rear, achieving progressive compression throughout the process. This avoids the looseness at the rear affecting the overall compaction effect. When the cover is opened, it indicates that the equipment is in a non-working state, and the pre-compression rollers automatically stop, preventing the second motor from running idle, reducing energy consumption and mechanical wear, extending the service life of the second motor and transmission components, and reducing long-term operating costs. At the same time, the combined design of pre-compaction and auxiliary compression reduces the workload and energy consumption of the main compaction mechanism, practicing the concept of low carbon and environmental protection.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please see Figures 1-11 One embodiment of the present invention is: a waste recycling device for FIBC processing, comprising a hollow frame 1, a hydraulic rod 4 mounted on the hollow frame 1, and a pressure plate 5 mounted on the hydraulic rod 4. The waste recycling device for FIBC processing further comprises: a compaction mechanism mounted on the hollow frame 1 for compacting the waste; the compaction mechanism comprises a slide rail 10 mounted on the hollow frame 1, a rack rod 11 slidably mounted in the slide rail 10, a top rod 12 slidably mounted on the rack rod 11, a slotted frame 13 mounted on the pressure plate 5, a positioning frame 14 mounted on the hollow frame 1, a slide rod 15 slidably mounted in the positioning frame 14, a positioning block 16 mounted on the slide rod 15, and an inclined slotted block 17 mounted on the slide rod 15; the contact surface between the positioning block 16 and the slotted frame 13 is set as an inclined surface; a first spring is provided between the positioning block 16 and the positioning frame 14, and the positioning block 16 is reset by the first spring.

[0030] The compaction mechanism also includes a motor 2 mounted on the hollow frame 1 and a hydraulic unit 3 mounted on the hollow frame 1; the hydraulic unit 3 is connected to the motor 2; the hydraulic unit 3 is connected to the hydraulic rod 4.

[0031] In the above embodiments, the pressure plate 5 is rigidly limited by the limiting mechanism when it is not in operation, which can prevent the pressure plate 5 from falling accidentally due to hydraulic system depressurization or misoperation, thus avoiding equipment damage and safety hazards. It is especially suitable for continuous operation scenarios in workshops. The limit is released only when the top rod 12 reaches the set position. The compaction action is only allowed to be performed when the weight condition is met, eliminating air pressure. For different sizes, material thicknesses, and fluffiness of the waste material in the container bag, the height of the top rod 12 can be adjusted by rotating the reciprocating screw rod 19, so that the weight threshold and displacement threshold for triggering compaction can be freely set.

[0032] The compaction mechanism also includes a reciprocating screw rod 19 rotatably mounted in the rack rod 11, a gravity plate 110 slidably mounted in the hollow frame 1, a gear 111 mounted on the hollow frame 1, a slider 112 mounted on the gravity plate 110, and a drive rack 113 mounted on the slider 112; the inner wall of the top rod 12 is provided with a groove that matches the reciprocating screw rod 19; a second spring is provided between the gravity plate 110 and the hollow frame 1, and the gravity plate 110 is reset by the second spring; the gear 111 meshes with the drive rack 113; the gear 111 meshes with the rack rod 11.

[0033] In the above embodiments, after the pressure plate 5 completes compaction and reset, the limiting mechanism automatically restores its limiting function, so that no manual reset or electrical control signal calibration is required, and the mechanical self-locking reliability is much higher than that of electrical control locking.

[0034] The waste recycling device for FIBC processing also includes a cleanup mechanism and a pretreatment mechanism; the cleanup mechanism is installed on the hollow frame 1 and is used to seal the compaction mechanism during operation and to push out the compressed material after the compaction mechanism has finished working; the pretreatment mechanism is installed on the hollow frame 1 and is used to perform preliminary compaction pretreatment on the FIBC before it enters the compaction mechanism.

[0035] In this embodiment, the container bags are mostly made of plastic materials such as polypropylene and polyethylene. During the cutting, sewing, and forming processes, a large amount of plastic scraps and waste bag bodies are generated. After these waste materials are put into the hollow frame 1, the motor 2 rotates, which sends hydraulic oil through the hydraulic unit 3 to the hydraulic rod 4 and drives the pressure plate 5 to compact the waste materials. Before the pressure plate 5 works, its displacement is restricted by the positioning block 16. Specifically, the positioning block 16 is inserted into the slot frame 13, and its non-sloping surface restricts the downward displacement of the pressure plate 5. Waste material is continuously added during the process, falling onto the gravity plate 110 supported by spring number two. As the weight of the waste material increases, the gravity plate 110 moves downward, simultaneously driving the slider 112 to move. The movement of the slider 112 drives the drive rack 113 to move, causing the gear 111 to rotate. The rotation of the gear 111 causes the rack 11 on one side to move upward along the slide frame 10. A push rod 12 is installed on the rack 11, so that after reaching a certain distance, it contacts the inclined surface of the inclined block 17, causing the inclined block 17 to move to the right under force. The movement of the slot block 17 causes the slide bar 15 to move, which in turn causes the positioning block 16 to move, disengaging it from the slot frame 13 and simultaneously compressing the first spring. At this point, the pressure plate 5 is released from its restraints and can move normally with the hydraulic rod 4. Since the waste material has significant variations in bulk and weight, traditional fixed-time, fixed-number compaction methods often result in incomplete compaction or wasted energy due to empty pressure. This solution uses the actual accumulated weight as the trigger condition; compaction only begins when the weight reaches the target, ensuring sufficient waste material for each compaction and consistent compaction results. In the non-working state, the pressure plate 5 is rigidly limited by a limiting mechanism to prevent liquid leakage. The system prevents pressure relief and accidental drop of the pressure plate 5 due to misoperation, avoiding equipment damage and safety hazards. It is especially suitable for continuous operation scenarios in workshops. The limit is released only when the top rod 12 reaches the set position. The compaction action is only allowed to be performed when the weight condition is met, eliminating the possibility of air pressure. The height of the top rod 12 can be adjusted by rotating the reciprocating screw rod 19 to freely set the weight threshold and displacement threshold for triggering compaction, depending on the size, thickness, and looseness of the waste material. For loose waste, the top rod 12 can be raised to increase the accumulation; for dense waste, the top rod 12 can be lowered to reduce the accumulation. One machine is suitable for all types of waste. In various waste material handling conditions, after the pressure plate 5 has been compacted and reset, the limiting mechanism automatically restores its limiting function. Specifically, the outer wall of the slot frame 13 first contacts the inclined surface of the positioning block 16, causing the positioning block 16 to move along the inner wall of the positioning frame 14 under force. At the same time, the first spring is compressed, and when the center point of the slot frame 13 is at the center point of the positioning block 16, the first spring drives the positioning block 16 to reset and insert into the slot frame 13, thereby re-limiting the pressure plate 5. This eliminates the need for manual reset and electrical control signal calibration, and the mechanical self-locking reliability is far higher than that of electrical control locking.

[0036] Example 2: Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the recovery mechanism includes a cover plate 20 rotatably mounted on the hollow frame 1, a locking groove 21 mounted on the cover plate 20, a mounting plate 22 mounted on the hollow frame 1, a rotating rod 23 rotatably mounted in the mounting plate 22, a locking rod 24 mounted on the rotating rod 23, an unlocking wheel 25 mounted on the rotating rod 23, and an L-shaped gear 26 mounted on the gravity plate 110; a first torsion spring is provided between the cover plate 20 and the hollow frame 1, and the cover plate 20 is reset by the first torsion spring; a second torsion spring is provided between the rotating rod 23 and the mounting plate 22, and the rotating rod 23 is reset by the second torsion spring; the unlocking wheel 25 and the L-shaped gear 26 mesh with each other.

[0037] In the above embodiment, the compaction chamber is closed by locking the cover plate 20, and the pressure of the pressure plate 5 is fully applied to the inside of the waste material, resulting in higher compaction density, more stable molding effect, reduced loosening and rebound, and easier subsequent transportation and recycling.

[0038] The aftermath mechanism also includes an electric push rod 27 installed on the hollow frame 1, a push plate 28 installed on the electric push rod 27, and a connecting rod 29 installed on the cover plate 20.

[0039] In the above embodiments, after compaction is completed, the electric push rod 27 drives the push plate 28 to automatically push out the compressed block, replacing manual material handling and reducing manual intervention, labor intensity and safety risks.

[0040] In this embodiment, before the compaction mechanism operates, the hollow part of the hollow frame 1 is covered by the cover plate 20, and after the cover plate 20 is in place, it is manually locked. Specifically, the cover plate 20 moves, causing the locking groove 21 to move. After the locking groove 21 passes through the locking rod 24, the rotating rod 23 is manually adjusted to rotate along the mounting plate 22 so that the locking rod 24 restricts the reset path of the locking groove 21. A connecting rod 29 is provided on the cover plate 20, which moves synchronously with the cover plate 20. After locking, the compaction chamber forms a closed space, and the pressure of the pressure plate 5 is fully applied to the inside of the waste material, resulting in higher compaction density, more stable molding effect, reduced loosening and rebound, and easier subsequent transportation and recycling. The movement of the gravity plate 110 drives the L-tooth rod 26 to move, so that the L-tooth rod 26 contacts the unlocking wheel 25 and drives the rotating rod 23 to rotate, making the locking rod 24 parallel to the locking groove 21. At this time, the cover plate 20 can be moved normally. Manual unlocking is also supported, which can be manually intervened when it is necessary to open the cover in advance or when the top rod 12 triggers the threshold adjustment. The dual unlocking methods are backups for each other, avoiding the failure of a single unlocking method that would cause the equipment to stop operating, improving the overall reliability and continuous operation capability. After compaction, the electric push rod 27 drives the push plate 28 to automatically push out the compressed block, replacing manual material handling and reducing manual intervention, labor intensity and safety risks.

[0041] Example 3: Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the pretreatment mechanism includes a placement plate 30 mounted on the hollow frame 1, a second motor 31 mounted on the hollow frame 1, and a sliding button 32 mounted on the output end of the second motor 31.

[0042] The pretreatment mechanism also includes a sliding frame 33 slidably installed in the placement plate 30, a transfer ring 34 sleeved in the sliding frame 33, and a connecting rope 35 for connecting the cover plate 20 and the sliding frame 33; a No. 3 spring is provided between the sliding frame 33 and the placement plate 30, and the sliding frame 33 is reset by the No. 3 spring; the transfer ring 34 contacts the slide button 32.

[0043] The pretreatment mechanism also includes a pre-pressing roller 36 rotatably mounted on the placement plate 30 and a receiving ring 37 mounted on the pre-pressing roller 36; both the receiving ring 37 and the transfer ring 34 are provided with inclined grooves, and the inclined grooves of the receiving ring 37 and the transfer ring 34 are matched with each other.

[0044] In the above embodiment, the inclined grooves of the two are matched with each other, so that when the motor 2 31 rotates counterclockwise, the receiving ring 37 can be driven to rotate through the sliding button 32. The rotation of the receiving ring 37 drives the pre-pressure roller 36 to rotate counterclockwise, which can prevent the pre-pressure roller 36 from accidentally rotating and getting caught in clothing or hands when opening the cover for maintenance, cleaning, or material handling, and greatly improve the safety of equipment operation.

[0045] The pretreatment mechanism also includes a connecting frame 38 mounted on the placement plate 30, an eccentric rod 39 rotatably mounted in the connecting frame 38, an undulating rod 310 slidably mounted on the placement plate 30, a pre-pressing plate 311 mounted on the undulating rod 310, and a connecting rod 312 for connecting the eccentric rod 39 and the undulating rod 310; the eccentric rod 39 and the pre-pressing roller 36 are connected by a belt drive.

[0046] In the above embodiment, while the front end is compacted by the pre-compression roller 36, the rear part that does not enter the pre-compression roller 36 is easy to remain loose. Through the reciprocating up and down movement of the pre-compression plate 311, the rear material can be continuously patted and assisted in compaction, so as to achieve progressive compression throughout the process and avoid the rear end from being loose and affecting the overall compaction effect.

[0047] In this embodiment, before the waste material enters the hollow frame 1, it is placed on the placement plate 30, and the front end of the waste material enters the pre-compression roller 36. The pre-compression roller 36 pre-compresses the waste material. Since the waste material is soft and large in volume, it is easy to cause feeding problems and insufficient compaction if it directly enters the main compaction mechanism. The symmetrical pre-compression rollers 36 can continuously roll the waste material to expel internal air, reduce its volume and thickness, reduce the hydraulic load of the main flattening machine, and improve the overall processing efficiency. At the same time, the rotation of the pre-compression roller 36 is transmitted to the eccentric rod 39 through the belt. This causes the eccentric rod 39 to rotate along the connecting frame 38, which in turn drives the connecting rod 312 to rotate. The rotation of the connecting rod 312 then drives the undulating rod 310 to move up and down along the placement plate 30. The movement of the placement plate 30 drives the pre-compression plate 311 to move synchronously, compacting the rear end of the waste material. When the waste material is long, while the front end is compacted by the pre-compression roller 36, the rear part that does not enter the pre-compression roller 36 is easily kept loose. Through the up and down reciprocating movement of the pre-compression plate 311, the rear material can be continuously patted and assisted in compaction, achieving progressive compression throughout the process. To prevent rear-end expansion from affecting the overall compaction effect, the power source of the preload roller 36 is connected to the output end of the motor 31, i.e., the receiving ring 37 is connected to the transfer ring 34. At this time, the cover plate 20 is in a sealed state. After the cover plate 20 is opened, the sliding frame 33 is moved by the movement of the connecting rod 29 through the connecting rope 35. The movement of the sliding frame 33 drives the transfer ring 34 to move, causing the transfer ring 34 to disengage from the receiving ring 37. At this time, the preload roller 36 loses its power source and stops rotating. After the cover plate 20 is sealed, the power source is connected to the motor 31. The connecting rope 35 pulls the sliding frame 33 to move, and at the same time stretches the No. 3 spring. The movement of the sliding frame 33 drives the transmission ring 34 to move along the slide button 32 and finally dock with the receiving ring 37. The inclined grooves opened by the two match each other, so that when the motor 2 31 rotates counterclockwise, the receiving ring 37 can be driven to rotate through the slide button 32. The rotation of the receiving ring 37 drives the pre-pressure roller 36 to rotate counterclockwise. This can prevent the pre-pressure roller 36 from accidentally rotating and getting caught in clothing or hands when opening the cover for maintenance, cleaning, or material handling, and greatly improve the safety of equipment operation.
