Description

Technical Field

[0001] The invention relates to the technical field of four-sided planer waste recycling equipment, in particular to a four-sided planer waste recycling mechanism. Background Art

[0002] In the woodworking industry, the four-side planer is a commonly used mechanical equipment for precise plane and corner processing of wood. With the improvement of automation, the requirements for cleanliness of the production environment are also getting higher and higher. Therefore, how to effectively collect the wood chips generated during the processing has become an urgent problem to be solved.

[0003] Common solutions on the market include using a vacuum cleaner directly connected to the equipment to absorb wood chips, or designing a special dust box to be placed under the equipment to catch the fallen waste. Although these methods can improve the working environment to a certain extent, due to the large amount of waste chips during the planing process, these two methods still have shortcomings in collection efficiency, equipment compatibility, and subsequent cleaning and maintenance. In addition, existing solutions often find it difficult to completely capture fine particles, resulting in a large amount of fine dust floating in the air, affecting the health of workers. At the same time, the cleaning process is cumbersome and requires frequent shutdowns for maintenance, which reduces production efficiency.

[0004] The invention patent with the authorization announcement number CN114474257B discloses a wood processing sawdust collection device with anti-blocking function. The device uses the operation of the exhaust fan to suck the sawdust generated during the wood cutting process into the feed pipe through the air diffuser. The sawdust in the feed pipe then falls into the protective cover. Driven by the exhaust fan, the chopped sawdust is discharged into the first collection box through the discharge pipe for centralized collection. The rotation of the second transmission wheel drives the rotation of the cutting knife to perform secondary chopping of the sawdust in the protective cover, effectively preventing the sawdust from clogging the exhaust fan. Although the device can effectively suck and collect the wood chips generated during the wood processing process and has the function of preventing the exhaust fan from being blocked, it still has the following shortcomings: 1. The device only relies on the suction component to collect the wood chips on the workbench, and its collection effect is closely related to the distance between the wood chips and the air diffuser, and the coverage area of ​​the air diffuser is limited, so it is difficult to ensure the comprehensive collection of the wood chips; 2. During the wood chip collection process, the exhaust fan directly acts on the wood chips, causing the wood chips to directly hit the exhaust fan blades, which can easily cause damage to the exhaust fan blades; 3. Since the wood chips contain a large amount of dust, the exhaust fan will suck in the dust during the suction process. The dust will not only adhere to the exhaust fan blades, but may also enter the exhaust fan, causing wear and tear, thereby reducing the service life of the equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a four-sided planer waste chip recovery mechanism, which effectively filters the waste chips through a rotating filter cartridge to ensure that the waste chips are intercepted and discharged from the discharge port. At the same time, the clean air entering the rotating filter cartridge is discharged through the exhaust fan, and the waste chips and dust will not contact the exhaust fan, thereby avoiding the problem of damage to the exhaust fan blades or wear of the internal mechanism, effectively extending the service life of the equipment, and improving the efficiency and stability of the entire recovery mechanism, with the advantages of high recovery efficiency, good recovery effect, and long equipment service life.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A four-sided planer waste chip recovery mechanism comprises a dust cover arranged above a workbench, waste chip collection ports are arranged between the side walls of the dust cover and the two sides of the workbench, a waste chip cleaning mechanism for sweeping waste chips in the middle of the workbench to the waste chip collection port is arranged above the workbench, a waste chip collection bucket is arranged at the bottom of the workbench, a waste chip dust removal mechanism is arranged at the bottom of the waste chip collection bucket, the waste chip dust removal mechanism comprises a fixed cylinder, a feed port connected to the bottom opening of the waste chip collection bucket is arranged at the top of the fixed cylinder, a rotating filter cylinder coaxial with the fixed cylinder is arranged inside the fixed cylinder, the inner cavity of the rotating filter cylinder is connected to the exhaust fan through an exhaust pipe, and the fixed cylinder is provided with a discharge port connected to the waste chip recovery mechanism.

[0008] By adopting the above technical scheme, the waste chip cleaning mechanism can effectively push the waste chips on the workbench away from the waste chip collection port to the side of the workbench close to the waste chip collection port, ensuring that the waste chips can be smoothly sucked into the waste chip collection port and fall into the waste chip collection bucket below for collection. Compared with the method of simply relying on negative pressure suction, the position of the waste chips can be effectively changed by cleaning, so that the waste chips reach a position closer to the waste chip collection port and are more easily sucked into the waste chip collection bucket by the exhaust fan, which not only reduces the load of the exhaust fan, but also improves the waste chip collection efficiency and effect. At the same time, after the exhaust fan is started, the waste chips can smoothly pass through the waste chip collection bucket and enter the inner cavity of the fixed cylinder. Under the gravitational force of the exhaust fan, the rotating filter cartridge can effectively filter the waste chips, ensuring that the waste chips are intercepted and discharged from the discharge port. At the same time, the clean air entering the rotary filter cartridge is discharged through the exhaust fan, ensuring that the waste chips and dust will not contact the exhaust fan, avoiding the problem of damage to the exhaust fan blades or wear of the internal mechanism, effectively extending the service life of the equipment, and improving the efficiency and stability of the entire recycling mechanism.

[0009] The present invention is further configured as follows: the two ends of the rotating filter cartridge respectively pass through the two ends of the fixed cylinder and are rotatably connected to the fixed cylinder, one end of the rotating filter cartridge is fixedly connected to the output shaft of a driving motor fixed on the outer wall of the dust cover, and the other end of the rotating filter cartridge is connected to the exhaust pipe through a rotating joint.

[0010] By adopting the above technical solution, the driving motor will drive the rotating filter cartridge to rotate at high speed once it is started. During the high-speed rotation, the rotating filter cartridge exerts a significant centrifugal force on the waste chips in contact with its outer wall, causing the wood chips to be pushed away from the filter cartridge under the action of centrifugal force, thereby avoiding the problem of waste chips adhering to the surface of the filter cartridge and causing clogging of the rotating filter cartridge. This not only helps to effectively separate waste chips from air, but also significantly improves the filtration efficiency.

[0011] The present invention is further configured as follows: the waste cleaning mechanism includes a cleaning brush parallel to the waste collecting port, and both ends of the cleaning brush are respectively connected to the cleaning drive mechanism.

[0012] By adopting the above technical solution, the cleaning drive mechanism is used to drive the cleaning brush to reciprocate along the workbench, thereby pushing the waste chips on the surface of the workbench to the waste chip collection port. The bristles have a certain elasticity, which can not only be in close contact with the surface of the workbench to achieve a good cleaning effect, but also can adapt to uneven surfaces and clean the workpiece being processed on the workbench without causing damage to the workbench and affecting the normal feeding of the workpiece.

[0013] The present invention is further configured as follows: the cleaning drive mechanism includes a cleaning drive rod which is parallel to the workbench and rotatably connected to the side walls of the dust cover on both sides; one end of the cleaning drive rod is connected to a driving motor 2 fixed on the outer wall of the dust cover; cams are fixedly provided at positions of the cleaning drive rod relative to the two waste collection ports; an inverted U-shaped frame is provided above the two cams; the bottom ends of the inverted U-shaped frame are respectively supported on the outer circles of the two cams; the top of the inverted U-shaped frame is longitudinally slidably matched with the fixed rod; the upper end of the fixed rod is fixedly connected to the top wall of the dust cover; the lower end of the fixed rod is connected to the cleaning brush through a connecting rod mechanism.

[0014] By adopting the above technical scheme, after the driving motor 2 is started, it drives the cleaning driving rod to rotate. When the cleaning driving rod rotates, it drives the cams at both ends to move, so that the inverted U-shaped frame moves back and forth along the fixed rod. During the up and down movement of the U-shaped frame, the two cleaning brushes are driven by the connecting rod mechanism to move back and forth in an orderly manner along the width direction of the workbench, thereby achieving the effect of continuously pushing the waste chips on the workbench toward the waste chip collection port, so that the waste chips on the workbench can be collected efficiently, and during the cleaning process, stable cleaning performance can be maintained for workpieces of different shapes and sizes, which greatly reduces the frequency of manual cleaning and reduces production costs.

[0015] The present invention is further configured as follows: the connecting rod mechanism includes connecting rod one and connecting rod two, the upper ends of connecting rod one and connecting rod two are hinged to the bottom of the fixed rod, the lower ends of connecting rod one and connecting rod two are respectively hinged to one end of lever one and lever two, the middle parts of lever one and lever two are provided with through holes connected to the cleaning drive rod, and after lever one and lever two are connected to the cleaning drive rod through the through holes, they can slide axially and rotate circumferentially along the cleaning drive rod, the other ends of lever one and lever two are respectively movably connected to the end of the cleaning brush opposite to them, and the middle parts of connecting rod one and connecting rod two are hinged to the U-shaped frame through adjusting rod one and adjusting rod two respectively.

[0016] By adopting the above technical scheme, when the U-shaped frame moves back and forth up and down along the fixed rod, it will drive the adjusting rod 1 and the adjusting rod 2 to make corresponding up and down movements. When the adjusting rod 1 and the adjusting rod 2 move up and down, the angle between the connecting rod 1 and the connecting rod 2 will increase or decrease periodically. In the process of periodic change of the angle between the connecting rod 1 and the connecting rod 2, the lever 1 and the lever 2 connected thereto will be driven to slide alternately along the driving axis in the direction away from or close to each other. In the sliding process, the lever 1 and the lever 2 will drive the cleaning brush to reciprocate between the middle part of the workbench and the side of the workbench close to the waste collection port. At the same time, due to the periodic change of the angle between the connecting rod 1 and the connecting rod 2, the height of the end hinged to the lever 1 and the lever 2 will also decrease or increase periodically, thereby causing the height of the cleaning brush movably connected to the other end of the lever 1 and the lever 2 to increase or decrease periodically, that is, the cleaning brush is close to the workbench When it is near one side of the waste collection port, its height is higher, and the bristles are separated from the workbench at this time. When it moves towards the middle of the workbench, the height of the cleaning brush gradually decreases until the bristles are against the workbench, so that when the cleaning brush reaches the middle of the workbench, the waste chips are cleaned from the middle of the workbench to both sides of the workbench. Therefore, in the process of reciprocating cleaning of the cleaning brush, the bristles continuously sweep the waste chips in the middle of the workbench to both sides of the workbench, and will not push the waste chips on both sides of the workbench to the middle of the workbench, thereby optimizing the cleaning process and improving the cleaning efficiency. Through the ingenious design of connecting rod one and connecting rod two, the adaptive adjustment of the cleaning brush height is realized, which ensures the cleaning efficiency while reducing the wear caused by excessive contact between the brush and the workbench. In addition, the rotation speed of the cleaning drive rod can be adjusted according to actual needs to adapt to the waste cleaning under different working conditions, further enhancing the applicability and flexibility of the device.

[0017] The present invention is further configured as follows: one end of the cleaning brush connected to lever one or lever two is provided with a connecting groove that slidably cooperates with lever one and lever two, the side wall of the connecting groove is provided with a waist-shaped pin hole, and the lever one and lever two are respectively provided with fixing pins at positions opposite to the waist-shaped pin holes on the side walls of the connecting groove, and the fixing pins can slide along the waist-shaped pin holes.

[0018] By adopting the above technical solution, lever one and lever two can slide relative to the cleaning brush after being connected with the fixed pin and the waist-shaped pin hole, ensuring that lever one and lever two can drive the cleaning brush to achieve smooth adjustment of the longitudinal height. At the same time, it is also convenient for disassembly and replacement of the cleaning brush, reducing the maintenance cost of the equipment and increasing the overall service life of the equipment.

[0019] The present invention is further configured as follows: the waste chip recovery mechanism includes a waste chip recovery chamber, the upper end of the waste chip recovery chamber is provided with a recovery port connected to the discharge port, the waste chip recovery chamber is provided with a pressing block that can reciprocate along the waste chip recovery chamber, one end of the pressing block is connected to the telescopic shaft of a driving cylinder fixed outside the waste chip recovery chamber, the side wall of the waste chip recovery chamber near the other end of the pressing block is provided with a discharge port, the discharge port is provided with a sealing door plate, and the sealing door plate is connected to the discharge port through a switch valve.

[0020] By adopting the above technical solution, after the waste chips enter the fixed cylinder, they will gradually fall into the waste chip recovery chamber from the discharge port below the fixed cylinder. The pressing block reciprocates under the action of the driving cylinder, continuously compressing the waste chips in the direction of the sealing door plate. When compressed to the set volume, the control switch valve starts to open the sealing door plate, so that the waste chips can be discharged from the discharge port, thereby realizing automatic collection and discharge of waste chips, which not only improves the efficiency of waste chip treatment, but also reduces the frequency of manual cleaning and labor intensity. In addition, the compressed waste chips are smaller in volume, which is convenient for transportation and storage, further reducing the total cost of waste chip treatment.

[0021] The present invention is further configured as follows: a plurality of baffle plates are fixedly provided on the outer wall of the rotary filter cartridge, and the baffle plates are arranged in a circular array on the outer wall of the rotary filter cartridge, and one end of each baffle plate away from the rotary filter cartridge abuts against the inner wall of the fixed cylinder, and the end of the baffle plate abutting against the inner wall of the fixed cylinder is provided with a wear-resistant rubber strip.

[0022] By adopting the above technical solution, the baffle plate separates the inner wall of the fixed cylinder and the outer wall of the rotating filter cylinder into multiple independent spaces. When the rotating filter cylinder rotates, each independent space passes through the feed port above the fixed cylinder in turn, so that the waste chips in the waste collection bucket can enter each space in turn and move to the discharge port with the rotating filter cylinder, avoiding the accumulation of waste chips above the discharge port and being unable to be discharged from the discharge port, reducing the equipment downtime caused by the accumulation of waste chips and improving the overall operating efficiency.

[0023] The beneficial effects of the present invention are:

[0024] The present invention also provides a method for cleaning the waste dust, thereby preventing the waste dust from being sucked into the dust collecting port and causing the waste dust to be sucked into the dust collecting port by the exhaust fan.

[0025] 2. Once the driving motor in the present invention is started, it will drive the rotating filter cartridge to rotate at high speed. During the high-speed rotation process, the rotating filter cartridge exerts a significant centrifugal force on the waste chips in contact with its outer wall, causing the wood chips to be pushed away from the filter cartridge under the action of centrifugal force, thereby avoiding the problem of waste chips adhering to the surface of the filter cartridge and causing clogging of the rotating filter cartridge. This not only helps to effectively separate waste chips from air, but also significantly improves the filtration efficiency.

[0026] 3. In the present invention, after the driving motor 2 is started, it drives the cleaning driving rod to rotate. When the cleaning driving rod rotates, it drives the cams at both ends of it to move, so that the inverted U-shaped frame moves back and forth along the fixed rod. During the up and down movement of the U-shaped frame, the two cleaning brushes are driven by the connecting rod mechanism to move back and forth in an orderly manner along the width direction of the workbench, thereby achieving the effect of continuously pushing the waste chips on the workbench toward the waste chip collection port, so that the waste chips on the workbench can be efficiently collected, and during the cleaning process, stable cleaning performance can be maintained for workpieces of different shapes and sizes, which greatly reduces the frequency of manual cleaning and reduces production costs.

[0027] 4. In the present invention, when the U-shaped frame moves reciprocatingly up and down along the fixed rod, it will drive the adjusting rod 1 and the adjusting rod 2 to perform corresponding up and down movements. When the adjusting rod 1 and the adjusting rod 2 move up and down, the angle between the connecting rod 1 and the connecting rod 2 will increase or decrease periodically. In the process of periodic change of the angle between the connecting rod 1 and the connecting rod 2, the lever 1 and the lever 2 connected thereto will be driven to slide alternately along the driving axis in the direction away from or close to each other. In the sliding process, the lever 1 and the lever 2 will drive the cleaning brush to reciprocate between the middle part of the workbench and the side of the workbench close to the waste collection port. At the same time, due to the periodic change of the angle between the connecting rod 1 and the connecting rod 2, the height of the end hinged to the lever 1 and the lever 2 will also decrease or increase periodically, thereby causing the height of the cleaning brush movably connected to the other end of the lever 1 and the lever 2 to increase or decrease periodically, that is, the cleaning brush is close to the waste collection port on the workbench. When the cleaning brush is on one side of the collection port, its height is higher, and the bristles are separated from the workbench at this time. When it moves towards the middle of the workbench, the height of the cleaning brush gradually decreases until the bristles are against the workbench, so that when the cleaning brush reaches the middle of the workbench, the waste debris is swept from the middle of the workbench to both sides of the workbench. Therefore, in the process of reciprocating cleaning of the cleaning brush, the bristles will only sweep the waste debris in the middle of the workbench to both sides of the workbench, and will not push the waste debris on both sides of the workbench to the middle of the workbench, thereby optimizing the cleaning process and improving the cleaning efficiency. Through the ingenious design of connecting rod one and connecting rod two, the adaptive adjustment of the cleaning brush height is realized, which ensures the cleaning efficiency while reducing the wear caused by excessive contact between the brush and the workbench. In addition, the rotation speed of the cleaning drive rod can be adjusted according to actual needs to adapt to the waste debris cleaning under different working conditions, further enhancing the applicability and flexibility of the device.

[0028] 5. After the waste chips enter the fixed cylinder, they will gradually fall into the waste chip recovery chamber from the discharge port below the fixed cylinder. The pressing block reciprocates under the action of the driving cylinder, continuously compressing the waste chips in the direction of the sealing door plate. When compressed to the set volume, the control switch valve starts to open the sealing door plate, so that the waste chips can be discharged from the discharge port. Therefore, the automatic collection and discharge of waste chips is realized, which not only improves the efficiency of waste chip treatment, but also reduces the frequency of manual cleaning and labor intensity. In addition, the compressed waste chips are smaller in size, which is convenient for transportation and storage, further reducing the total cost of waste chip treatment.

[0029] 6. The present invention divides the inner wall of the fixed cylinder and the outer wall of the rotating filter cylinder into multiple independent spaces through the barrier plate. When the rotating filter cylinder rotates, each independent space passes through the feed port above the fixed cylinder in turn, so that the waste chips in the waste collection bucket can enter each space in turn and move to the discharge port with the rotating filter cylinder, avoiding the accumulation of waste chips above the discharge port and being unable to be discharged from the discharge port, reducing the equipment downtime caused by the accumulation of waste chips and improving the overall operating efficiency.

[0043] Furthermore, a plurality of baffle plates 67 are fixedly provided on the outer wall of the rotary filter cartridge 63, and the baffle plates 67 are arranged in a circular array on the outer wall of the rotary filter cartridge 63. One end of each baffle plate 67 away from the rotary filter cartridge 63 abuts against the inner wall of the fixed cylinder 61, and the end of the baffle plate abutting against the inner wall of the fixed cylinder 61 is provided with a wear-resistant rubber strip.

[0044] The working principle of the present invention is as follows: first, the control driving motor 2 85 is started. After the driving motor 2 85 is started, the cleaning driving rod 81 is driven to rotate. When the cleaning driving rod 81 rotates, the cams 82 at both ends thereof are driven to move, so that the inverted U-shaped frame 83 moves up and down reciprocatingly along the fixed rod 84, and the adjusting rod 1 97 and the adjusting rod 2 98 are driven to move up and down accordingly. When the adjusting rod 1 97 and the adjusting rod 2 98 move up and down, the angle between the connecting rod 1 91 and the connecting rod 2 92 is periodically increased or decreased. In the process of periodic change of the angle between the connecting rod 1 91 and the connecting rod 2 92, the lever 1 93 and the lever 2 94 connected thereto are driven to slide alternately in the direction away from or close to each other along the driving axis. The lever 1 93 and the lever 2 94 are driven to slide alternately in the direction away from or close to each other along the driving axis. When the rod 2 94 slides, it will drive the cleaning brush 41 to reciprocate between the middle of the workbench 1 and the side of the workbench 1 close to the waste collection port 3. At the same time, due to the periodic change of the angle between the connecting rod 1 91 and the connecting rod 2 92, the height of the end hinged to the lever 1 93 and the lever 2 94 will also periodically decrease or increase, thereby causing the height of the cleaning brush 41 movably connected to the other end of the lever 1 93 and the lever 2 94 to periodically increase or decrease, that is, when the cleaning brush 41 is on the side of the workbench 1 close to the waste collection port 3, its height is higher, and the bristles are separated from the workbench 1 at this time, and when moving towards the middle of the workbench 1, the height of the cleaning brush 41 gradually decreases until the bristles are against the workbench 1. The cleaning brush 41 is convenient for cleaning the waste from the middle of the workbench 1 to the two sides of the workbench 1. Therefore, in the process of reciprocating cleaning of the cleaning brush 41, the bristles continuously sweep the waste from the middle of the workbench 1 to the two sides of the workbench and push them toward the waste collection port 3, ensuring that the waste can be smoothly sucked into the waste collection port 3 and fall into the waste collection bucket 5 below for collection; then, under the gravitational force of the exhaust fan, the waste enters the inner cavity of the fixed cylinder 61 from the bottom opening of the waste collection bucket 5, and the rotating filter cylinder 63 effectively filters the waste while rotating, ensuring that the waste is intercepted and discharged from the discharge port. At the same time, the clean air entering the rotating filter cylinder 63 is discharged through the exhaust fan, ensuring Waste chips and dust will not come into contact with the exhaust fan, avoiding the problem of damage to the exhaust fan blades or wear of the internal mechanism; after the waste chips enter the fixed cylinder 61, they will gradually fall into the waste chip recovery chamber 71 from the discharge port below the fixed cylinder 61, and the pressing block 73 will reciprocate under the action of the driving cylinder 74, continuously compressing the waste chips in the direction of the sealing door plate 76. When compressed to a set volume, the control switch valve will start to open the sealing door plate 76, so that the waste chips can be discharged from the discharge port 75, thereby realizing automatic collection and discharge of waste chips, which not only improves the efficiency of waste chip treatment, but also reduces the frequency of manual cleaning and reduces labor intensity. In addition, the compressed waste chips are smaller in volume, which is convenient for transportation and storage, further reducing the total cost of waste chip treatment.
