A waste collecting device for paperboard processing

Abstract

This utility model discloses a waste collection device for cardboard processing, relating to the field of shredder blowers. The utility model includes a shredder blower and a collection device. The air outlet of the shredder blower is connected to the collection device via an air guide pipe. A ventilation fan is installed on one side of the air guide pipe via a clearing mechanism. The ventilation fan provides reverse airflow within the air guide pipe. When the air guide pipe becomes blocked, the control panel activates the clearing mechanism, and an electric actuator drives a movable plate to move, blocking the connection between the air guide pipe and the collection device and stopping the shredder blower. This prevents waste from accumulating and worsening the blockage. Simultaneously, a second connecting pipe connects to the air guide pipe, allowing the reverse airflow generated by the ventilation fan to enter the air guide pipe through the second connecting pipe. This directional impact directly peels off and removes the shredded material from the blocked area, achieving rapid clearing and quickly restoring normal waste transport, thus improving overall operating efficiency and ease of use.

Description

Technical Field

[0001] This utility model relates to the field of paper shredders, specifically a waste collection device for cardboard processing. Background Technology

[0002] Shredders are mainly used in the collection of paperboard waste for automated processing of trimming waste, die-cut edges and scrap paperboard from corrugated cardboard production. They shred the waste by high-speed rotating blades and use air power to transport it to a separator or waste paper room, achieving efficient recycling.

[0003] When using existing paper shredders, the power of the blower needs to be selected according to the usage environment and the amount of waste paperboard to be processed. If there is a mismatch, paperboard may become blocked inside the air guide and flow pipe, which brings certain difficulties to the collection of waste paperboard. In view of this, the inventor urgently needs to design a paperboard collection mechanism that can effectively unclog the blockage, thereby improving the ease of use of the paperboard collection device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a waste collection device for cardboard processing, so as to solve the technical problem that the shredder blower is prone to pipe blockage due to power mismatch in cardboard waste collection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste collection device for cardboard processing, comprising a shredder fan and a collection device, wherein the air outlet of the shredder fan is connected to the collection device through an air guide pipe, and a ventilation fan is installed on one side of the air guide pipe through a clearing mechanism, wherein the ventilation fan provides reverse airflow in the air guide pipe for clearing.

[0006] The unblocking mechanism includes a first connecting pipe and a second connecting pipe, which are connected to the air guide pipe. One side of the second connecting pipe is connected to the air outlet flange of the unblocking fan.

[0007] By adopting the above technical solution, the paper shredder fan, air duct, and collection device are connected to achieve the integrated function of paperboard waste shredding, conveying and centralized processing, which significantly improves the waste recycling efficiency. At the same time, the addition of a ventilation fan and unblocking mechanism, and the use of the dual-channel structure of the first and second connecting pipes, provides reverse airflow impact when the air duct is blocked, effectively solving the problem of easy blockage in traditional single-channel conveying.

[0008] Furthermore, an electric actuator is installed on the flange at the end of the first connecting pipe away from the air guide pipe, and a movable plate is installed on the telescopic end of the electric actuator. The movable plate is used to block the connection between the air guide pipe and the collecting device / the second connecting pipe and the air guide pipe.

[0009] By adopting the above technical solution, the airflow path switching between the air guide tube, the collecting device, and the second connecting tube is realized. The telescopic design of the movable plate can accurately control the airflow to be opened or blocked, avoiding the problem of low efficiency of traditional manual valve adjustment.

[0010] Furthermore, when the shredder is working normally, the movable plate blocks the connection between the second connecting pipe and the air guide pipe, and at the same time isolates the ventilation fan.

[0011] By adopting the above technical solution, when the shredder blower is working normally, the movable plate blocks the connection between the second connecting pipe and the air guide pipe, ensuring that all the positive airflow generated by the shredder blower is delivered to the collection device, avoiding airflow diversion that would lead to a decrease in conveying efficiency.

[0012] Furthermore, during the unblocking process, the movable plate is driven by an electric actuator to block the connection between the air guide pipe and the collecting device, while the second connecting pipe is connected to the air guide pipe.

[0013] By adopting the above technical solution, during the unblocking process, the electric push rod drives the movable plate to block the connection between the air duct and the collection device, quickly cutting off the main delivery channel and preventing the blockage from worsening. At the same time, through the connection between the second connecting pipe and the air duct, a directional path is provided for the reverse airflow impact of the unblocking fan, which can accurately locate the blockage area and use high-pressure reverse airflow to peel off and unblock the shredded cardboard, avoiding the risk of physical damage to the pipeline caused by traditional mechanical unblocking.

[0014] Furthermore, a control panel is installed on the front side of the collecting device and in a position accessible to the operator, and the shredder fan, ventilation fan and electric actuator are all electrically connected to the control panel.

[0015] By adopting the above technical solutions, operators can centrally control the working status of the shredder fan, ventilation fan, and electric actuator, simplifying the complexity of multi-device collaborative management and reducing the risk of misoperation.

[0016] Furthermore, the shredder has an impeller mounted inside, and several cutting teeth are equidistantly arranged in a ring at the center of the impeller.

[0017] By adopting the above technical solution, the cardboard waste is cut at multiple angles through high-speed rotation, which greatly improves the uniformity and efficiency of crushing and avoids the problem of incomplete crushing caused by local wear of traditional blades.

[0018] Furthermore, the collecting device is a paper gas separator or a collecting container.

[0019] By adopting the above technical solutions, the waste treatment needs of different production scenarios can be met. The paper-air separator achieves effective separation of shredded material and airflow through centrifugal force or screening structure, improving the purity of waste recycling and reducing dust emissions. The collection container is suitable for direct storage of shredded material, which is convenient for subsequent packaging or transportation.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention utilizes a clearing mechanism and a clearing fan. When the air duct becomes blocked, the control panel activates the clearing mechanism, and the electric actuator drives the movable plate to move, blocking the connection between the air duct and the collection device, and stopping the shredder fan to prevent waste from accumulating and worsening the blockage. Simultaneously, the second connecting pipe connects to the air duct, and the reverse airflow generated by the clearing fan enters the air duct through the second connecting pipe, directionally impacting the blocked area, directly peeling off and removing the shredded material, achieving rapid clearing, quickly restoring normal waste transport, minimizing downtime, and improving overall operating efficiency and ease of use.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A waste collection device for cardboard processing, such as Figure 1-4As shown, it includes a paper shredder 1 and a collection device 3. The air outlet of the paper shredder 1 is connected to the collection device 3 through an air duct 2. One side of the air duct 2 is connected to a ventilator 5 installed through a ventilator 4. The ventilator 5 provides reverse airflow in the air duct 2 for ventilating.

[0030] The unblocking mechanism 4 includes a first connecting pipe 401 and a second connecting pipe 402, which are connected to the air guide pipe 2. One side of the second connecting pipe 402 is connected to the air outlet flange of the unblocking fan 5. Through the connection between the shredder fan 1, the air guide pipe 2, and the collection device 3, the integrated function of crushing, conveying, and centralized processing of cardboard waste is realized, which significantly improves the waste recycling efficiency. At the same time, the unblocking fan 5 and the unblocking mechanism 4 are added. By utilizing the dual-channel structure of the first connecting pipe 401 and the second connecting pipe 402, a reverse airflow impact is provided when the air guide pipe 2 is blocked, which effectively solves the problem of easy blockage in traditional single-channel conveying. Through the bidirectional airflow switching mechanism, the continuity of normal conveying is ensured, and the blockage can be quickly cleared, reducing the frequency of downtime maintenance and improving system stability.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An electric actuator 403 is installed on the flange at the end of the first connecting pipe 401 away from the air guide pipe 2. A movable plate 404 is installed on the telescopic end of the electric actuator 403. The movable plate 404 is used to block the connection between the air guide pipe 2 and the collecting device 3 / the second connecting pipe 402 and the air guide pipe 2, realizing the switching of the airflow path between the air guide pipe 2 and the collecting device 3 and the second connecting pipe 402. The telescopic design of the movable plate 404 can accurately control the airflow to be opened or blocked, avoiding the problem of low efficiency of traditional manual valve adjustment. At the same time, the mechanical drive of the electric actuator 403 ensures the stability and reliability of the displacement of the movable plate 404, and can maintain the sealing even in high pressure or high dust environment, preventing airflow leakage or secondary blockage.

[0032] See Figure 3 , Figure 4 When the shredder 1 is working normally, the movable plate 404 blocks the connection between the second connecting pipe 402 and the air guide pipe 2, and at the same time isolates the ventilator fan 5. When the shredder 1 is working normally, the movable plate 404 blocks the connection between the second connecting pipe 402 and the air guide pipe 2, ensuring that all the positive airflow generated by the shredder 1 is delivered to the collection device 3, avoiding airflow diversion that would reduce the conveying efficiency. At the same time, the isolation design of the movable plate 404 for the ventilator fan 5 prevents the reverse airflow from interfering with the main airflow path during normal operation, maintains the system pressure balance, and ensures the continuity of waste conveying. The structural setting in this state also reduces the ineffective energy consumption of the ventilator fan 5 and optimizes the overall system energy utilization rate.

[0033] See Figure 3 , Figure 4 During the unblocking process, the movable plate 404 is driven by the electric actuator 403, blocking the connection between the air duct 2 and the collecting device 3. The second connecting pipe 402 is connected to the air duct 2. During the unblocking process, the electric actuator 403 drives the movable plate 404 to block the connection between the air duct 2 and the collecting device 3, quickly cutting off the main conveying channel and preventing the blockage from worsening. At the same time, the connection between the second connecting pipe 402 and the air duct 2 provides a directional path for the reverse airflow impact of the unblocking fan 5, which can accurately locate the blockage area and use high-pressure reverse airflow to peel off and unblock the shredded cardboard, avoiding the risk of physical damage to the pipeline caused by traditional mechanical unblocking. At the same time, the linkage mechanism of airflow impact and mechanical blocking shortens the unblocking response time and reduces production delays caused by downtime.

[0034] See Figure 1 , Figure 2 A control panel 6 is installed on the front side of the collecting device 3 and in a position accessible to the operator. The shredder fan 1, the ventilation fan 5, and the electric actuator 403 are all electrically connected to the control panel, allowing the operator to centrally control the working status of the shredder fan 1, the ventilation fan 5, and the electric actuator 403. This simplifies the complexity of multi-device collaborative management, reduces the risk of misoperation, and the accessible layout of the control panel 6 facilitates real-time monitoring of system operating parameters and supports one-click start of the dredging program, improving the convenience of emergency handling.

[0035] See Figure 1 , Figure 2 The shredder blower 1 has an impeller installed inside, and several cutting teeth are installed in a ring at equal intervals at the center of the impeller. Through high-speed rotation, the paperboard waste is cut at multiple angles, which greatly improves the uniformity and efficiency of shredding. It avoids the problem of incomplete shredding caused by local wear of traditional blades. At the same time, the ring cutting teeth have high structural strength and can withstand the impact of hard paperboard or mixed foreign objects, extending the service life of the blades. It also optimizes the mixing effect of airflow and shredded material, making the shredded material easier to be transported with the airflow and reducing the residual accumulation inside the blower.

[0036] See Figure 1 , Figure 2 The collecting device 3 consists of a paper gas separator and a collecting container, which can adapt to the waste treatment needs of different production scenarios. The paper gas separator achieves effective separation of shredded material and airflow through centrifugal force or screening structure, improving the purity of waste recycling and reducing dust emissions. The collecting container is suitable for direct storage of shredded material, which is convenient for subsequent packaging or transportation. At the same time, the integration of the paper gas separator can reduce the load on subsequent dust removal equipment and optimize the overall environmental performance. The sealed design of the collecting container prevents the shredded material from getting damp or being secondary contaminated during storage, ensuring the quality of waste reuse.

[0037] The implementation principle of this embodiment is as follows: When the shredder blower 1 is running, the cardboard waste is sucked in and shredded, and then transported to the collection device 3 for centralized processing through the air duct 2. When the air duct 2 is blocked, the control panel 6 activates the unblocking mechanism 4, and the electric push rod 403 drives the movable plate 404 to move, blocking the connection between the air duct 2 and the collection device 3, and stopping the operation of the shredder blower 1. At the same time, the second connecting pipe 402 is connected to the air duct 2. At this time, the reverse airflow generated by the unblocking fan 5 enters the air duct 2 through the second connecting pipe 402 and performs reverse impact unblocking on the blocked part. After unblocking is completed, the electric push rod 403 resets the movable plate 404 and restores the normal working state of the shredder blower 1. This process achieves automatic anti-blocking through airflow switching and mechanical linkage, ensuring the stable operation of the waste collection system.
