Description

Technical Field

[0001] This invention relates to the field of equipment cleaning technology, and in particular to a cleaning device for the chain conveyor of a shredder. Background Technology

[0002] A shredder is a device used to cut tobacco leaves, stems, and other raw materials into shreds. The chain conveyor is a crucial component of the shredder's feeding mechanism. Because the chain conveyor is in direct contact with the material, debris and tobacco oil easily adhere to its surface and seep into its gaps. If dirt accumulates on the chain surface and in the gaps, it can easily cause the tobacco leaves to slip during the feeding process, resulting in uneven shred width. Furthermore, debris stuck in the gaps can cause the chain to deviate from its running trajectory, leading to equipment malfunction and shutdown.

[0003] Currently, existing chain cleaning devices for shredders have the defect of incomplete cleaning. Impurities such as tobacco dust, moisture, and tobacco oil in the material not only adhere to the surface of the chain, but also easily seep into the connection gaps of the chain. This causes the tobacco leaves to slip during the material conveying process and results in uneven shredding width, reducing shredding quality and shredding efficiency.

[0004] Therefore, there is an urgent need to propose a chain cleaning device for shredders to solve the above problems. Summary of the Invention

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] The existing chain cleaning device for shredders has the defect of incomplete cleaning. Impurities such as tobacco dust, moisture and grease in the material not only adhere to the surface of the chain, but also easily seep into the connection gaps of the chain. This causes the tobacco leaves to slip during the material conveying process and results in uneven shredding width, reducing shredding quality and shredding efficiency.

[0024] Based on the above issues, such as Figure 1 As shown, this embodiment provides a chain cleaning device for a shredder. The shredder chain cleaning device includes a shredder body 1, a conveying assembly 2, a shredding mechanism 3, and a cleaning assembly 4. The shredder body 1 is provided with a cavity 11. The conveying assembly 2 is disposed within the cavity 11 and includes an annular chain 21. The annular chain 21 includes a conveying section 211 extending along a first direction and a return section 212. The conveying section 211 is located above the return section 212 and is used to convey tobacco shreds. The shredding mechanism 3 is disposed within the cavity 11 and is located above the conveying section 211. The shredding mechanism 3 is configured to cut the material conveyed by the conveying section 211. The material can be tobacco leaves, tobacco stems, and other raw materials. The cleaning component 4 is located below the return section 212. The cleaning component 4 includes a blowing component 41, a scraper 42, a brush 43, and a drying component 44, arranged sequentially and at intervals along the moving direction of the return section 212. The blowing component 41 is configured to blow away impurities on the return section 212; the scraper 42 is configured to scrape away impurities on the return section 212; the brush 43 is configured to clean residual impurities on the return section 212; and the drying component 44 is configured to dry the return section 212. It should be noted that the shredding mechanism 3 is prior art, and its specific structure and working principle will not be described in detail here. The length extension direction of the shredder body 1 extends along a first direction. In this embodiment, the first direction is the X direction. The conveying section 211 and the return section 212 of the annular chain 21 both convey along the X direction, and their conveying directions are opposite.

[0025] The shredding mechanism 3 in the chain cleaning device of the shredding machine can cut the material conveyed by the conveying section 211 of the annular chain 21 into tobacco shreds. During the rotation of the annular chain 21, after the conveying section 211 completes the conveying of tobacco shreds, it turns to the return section 212. At this time, the return section 212 of the annular chain 21 needs to be cleaned. Since the cleaning component 4 is located below the return section 212, and the cleaning component 4 includes a blowing component 41, a scraper 42, a brush 43 and a drying component 4 arranged sequentially and at intervals along the moving direction of the return section 212. 4. The blowing component 41 can initially blow away impurities on the surface of the return section 212, the scraper 42 can scrape off the impurities adhering to the surface of the return section 212, the brush 43 is used to further clean the fine impurities remaining on the surface of the return section 212, and the drying component 44 can dry and dehumidify the cleaned return section 212, so that the impurities on the surface of the return section 212 are thoroughly cleaned and kept dry, which facilitates the stable conveying of tobacco shreds, avoids slippage during the conveying of tobacco shreds, improves the quality of shredding, and improves the efficiency of shredding operations.

[0026] Specifically, the conveying assembly 2 further includes a driving component, a transmission sprocket 22, and a driven sprocket 23. The transmission sprocket 22 and the driven sprocket 23 are spaced apart along a first direction and are rotatably connected to the shredder body 1. The two ends of the annular chain 21 along the first direction are respectively wound around the transmission sprocket 22 and the driven sprocket 23. The driving component is driven and connected to the transmission sprocket 22, and the driving component can drive the transmission sprocket 22 to rotate around its own axis, thereby driving the driven sprocket 23 to rotate through the annular chain 21, thus realizing the cyclic conveying of the annular chain 21. The top of the shredder body 1 is provided with a feed inlet 15, and the feed inlet 15 and the shredding mechanism 3 are arranged sequentially along the direction of conveying tobacco shreds in the conveying section 211.

[0027] A discharge port is provided on the side wall of the shredder body 1 near the downstream end of the conveying section 211. A discharge plate 17 is installed at the discharge port. One end of the discharge plate 17 is inclined towards the downstream end of the conveying section 211, and the other end of the discharge plate 17 extends outward towards the outside of the shredder body 1. Tobacco shreds enter the cavity 11 inside the shredder body 1 through the feed port 15 and fall onto the conveying section 211 of the annular chain 21. The annular chain 21 then continuously conveys the tobacco shreds to the location of the shredder mechanism 3. After the shredder mechanism 3 performs shredding operations on tobacco leaves, tobacco stems and other raw materials, the conveying section 211 continues to convey the tobacco shreds formed from the shredded raw materials to its downstream end. Under the action of gravity and the conveying action of the annular chain 21, the tobacco shreds leave the conveying section 211 and fall above the discharge plate 17. Finally, under the guidance of the inclined discharge plate 17, they are discharged from the shredder body 1 through the discharge port. In this embodiment, the driving component can be a servo motor, which only needs to drive the transmission sprocket 22 to rotate stably, and no specific limitation is made here.

[0028] In some embodiments, such as Figure 1 and Figure 2 As shown, the purging component 41 includes an air pump 411 and a spray holder 412. The air inlet 4111 of the air pump 411 extends to the outside of the shredder body 1, and the air outlet 4112 of the air pump 411 is connected to the spray holder 412. Several nozzles 413 are provided on the side of the spray holder 412 facing the return section 212. When the annular chain 21 rotates from the conveying section 211 to the return section 212, the nozzles 413 on the spray holder 412 can perform preliminary purging of impurities on the surface of the return section 212, and the multiple nozzles 413 can effectively increase the purging area and improve the purging effect.

[0029] Furthermore, the two opposite side walls of the shredder body 1 along the first direction are a first side wall 12 and a second side wall 13, wherein the first side wall 12 is located on the side of the shredder body 1 away from the downstream of the conveying section 211 along the first direction, and the second side wall 13 is located on the side of the shredder body 1 close to the downstream of the conveying section 211 along the first direction.

[0030] Specifically, a support base 414 is provided on the second side wall 13. The support base 414 is vertically installed on the outer wall of the second side wall 13. The air pump 411 is installed on the top of the support base 414 and is located below the discharge plate 17.

[0031] Furthermore, the air inlet 4111 of the air pump 411 is equipped with a first filter 415. The first filter 415 can effectively prevent impurities in the air from entering the air pump 411, ensuring the normal operation of the air pump 411.

[0032] In other embodiments, such as Figure 1 and Figure 3 As shown, the drying component 44 includes a hot air blower 441 and an air guide shroud 442. One end of the air guide shroud 442 is connected to the air outlet of the hot air blower 441, and the other end is open towards the return section 212. The air guide shroud 442 can direct the hot air generated by the hot air blower 441 to the return section 212, improve the drying effect on the surface of the return section 212, and effectively improve the cleaning efficiency of the annular chain 21.

[0033] Specifically, the bottom of the annular chain 21 is provided with a mounting base 45. The scraper 42, brush 43 and hot air blower 441 are sequentially installed on the mounting base 45 along the moving direction of the return section 212. The mounting base 45 can be detachably installed on the inner wall of the shredder body 1. This arrangement facilitates the maintenance and replacement of the cleaning components 4 of the annular chain 21.

[0034] It should be noted that the scraper 42 has a scraping blade at its end, which is made of a wear-resistant flexible material, including but not limited to wear-resistant nylon and wear-resistant rubber, etc., without specific limitations here. This design ensures the cleaning effect of the chain conveyor while effectively protecting the annular chain 21 and extending its service life. In addition, in this embodiment, the brush 43 consists of multiple rows of bristles, which are spaced apart along the moving direction of the return section 212. This design allows the multiple rows of bristles to effectively clean residual impurities on the surface of the return section 212, improving the cleaning effect of the annular chain 21.

[0035] In some embodiments, see Figure 1 and Figure 4 The shredder chain cleaning device also includes a collection component 5, which includes a collection box 51. The collection box 51 is located at the bottom of the cavity 11 and is configured to receive impurities falling from the annular chain 21. This configuration allows for centralized collection of impurities, preventing them from scattering and facilitating the cleaning and maintenance of the shredder chain cleaning device.

[0036] Specifically, the side wall of the collection box 51 is provided with a discharge port 511, and the side wall of the shredder body 1 is provided with a corresponding waste discharge port 16. The waste discharge port 16 and the discharge port 511 are adapted in shape and communicate with each other. Impurities in the collection box 51 can be discharged through the discharge port 511 and the waste discharge port 16. In this embodiment, the waste discharge port 16 is provided on the first side wall 12 of the shredder body 1, and the discharge port 511 is correspondingly provided on the side of the collection box 51 along the X direction close to the first side wall 12. The waste discharge port 16 and the discharge port 511 are correspondingly provided and communicate with each other.

[0037] Furthermore, the collection assembly 5 also includes a second filter 52, which covers the top of the collection box 51. The second filter 52 is configured to perform solid-liquid separation on the falling impurities. Since the gas blown by the suction pump 411 to the return section 212 contains moisture, this moisture adheres to the tobacco waste formed after the tobacco leaves, stems and other raw materials are shredded, and falls onto the second filter 52 with the tobacco waste. In addition, the tobacco leaves, stems and other raw materials contain a small amount of tobacco oil. The tobacco waste and tobacco oil fall with the gas blown by the suction pump 411. By setting the second filter 52, the second filter 52 only allows liquid to pass through. The tobacco oil and moisture can enter the collection box 51 under the action of gravity, while the tobacco waste is trapped on the second filter 52. The tobacco oil and moisture collected in the collection box 51 can be discharged sequentially through the discharge port 511 and the waste discharge port 16. In addition, operators can periodically remove the second filter screen 52 to collect and process the tobacco waste trapped on it, enabling effective recycling of tobacco waste and centralized treatment of tobacco oil and moisture. By setting up the second filter screen 52 to separate the tobacco waste into solid and liquid components, it is possible to effectively prevent the tobacco waste from sticking together with tobacco oil or moisture and clogging the collection box 51, reducing the difficulty of equipment cleaning and maintenance and extending the service life of the equipment.

[0038] It should be noted that the pore size of the second filter screen 52 can be selected according to actual usage, as long as it can achieve solid-liquid separation of tobacco scraps, meaning that liquid can pass through the second filter screen 52 into the collection box 51, while tobacco scraps cannot pass through the second filter screen 52 into the collection box 51. Furthermore, the second filter screen 52 is detachably connected to the top of the collection box 51. The detachable connection between the second filter screen 52 and the collection box 51 can be a screw connection or a snap-fit ​​connection between a clip and a slot; no specific limitation is made in this embodiment. The operator can remove the second filter screen 52 to collect and clean the tobacco waste on it, facilitating the recycling of tobacco waste.

[0039] In other embodiments, see Figure 4 and Figure 5The collection component 5 also includes a driving component 53 and a pusher component 54. The pusher component 54 is positioned above the second filter screen 52. The driving component 53 is connected to the pusher component 54 and drives the pusher component 54 to reciprocate along a first direction. The pusher component 54 pushes solid impurities on the second filter screen 52. With this configuration, the pusher component 54 can continuously reciprocate along the first direction under the drive of the driving component 53. The pusher component 54 pushes the solid impurities on the second filter screen 52 to the side of the second filter screen 52, making it easier for operators to collect the solid impurities. Simultaneously, it prevents the accumulation of solid impurities from clogging the filter pores of the second filter screen 52, ensuring that liquid can smoothly pass through the second filter screen 52 to achieve solid-liquid separation, improving the automation level of the device, and reducing manual labor intensity.

[0040] Furthermore, the drive component 53 includes a lead screw 531 and a motor 532. The motor 532 is mounted on the first side wall 12. One end of the lead screw 531 is rotatably connected to the inner side of the second side wall 13. The motor 532 is driven and connected to the other end of the lead screw 531 and is used to drive the lead screw 531 to rotate. The lead screw 531 is threadedly driven and connected to the push plate component 54. By driving the lead screw 531 to rotate through the motor 532, the push plate component 54 can be stably driven to achieve precise reciprocating motion, ensuring the stable and reliable pushing action of the push plate component 54 and improving the stability of equipment operation.

[0041] In some embodiments, see Figure 1 and Figure 6 The pusher plate component 54 includes a connecting block 541 and a pusher plate 542. The connecting block 541 has a threaded hole 5411, which is threadedly connected to the lead screw 531. The pusher plate 542 is detachably connected to the connecting block 541. When the motor 532 drives the lead screw 531 to rotate in the forward or reverse direction, the connecting block 541, which is threadedly connected to the lead screw 531, can perform linear reciprocating motion in the first direction, thereby driving the pusher plate 542 to move synchronously to push tobacco impurities. This improves the stability of the pusher plate 542 when it moves in the first direction. At the same time, the pusher plate 542 is detachably connected to the connecting block 541, which facilitates the disassembly, cleaning, and replacement of the pusher plate 542, extends the service life of the pusher plate 542, reduces the difficulty and cost of device maintenance, and ensures the normal operation of the chain cleaning device of the shredder.

[0042] Specifically, the bottom of the connecting block 541 is also connected to a connecting plate 543. The bottom of the connecting plate 543 is detachably connected to a push plate 542. The bottom of the connecting plate 543 is provided with a snap-fit ​​groove 545. The top of the push plate 542 is provided with a snap-fit ​​block 544 that is compatible with the snap-fit ​​groove 545. The connecting plate 543 and the push plate 542 are connected by snap-fit ​​block 544 and snap-fit ​​groove 545, which facilitates the disassembly, cleaning and replacement of the push plate 542 and reduces the difficulty and cost of device maintenance.

[0043] Furthermore, a guide rod 55 is connected to the connecting block 541, and a guide groove 14 extending along the first direction is provided on the inner wall of the shredder body 1. The guide rod 55 is slidably connected to the guide groove 14. The sliding engagement between the guide rod 55 and the guide groove 14 can guide the reciprocating motion of the push plate 542 along the first direction, preventing the push plate 542 from deviating during its movement and improving the stability of the push plate 542's movement.

[0044] Specifically, at least one end of the guide groove 14 is provided with a limiting rod 56, which is used to stop the guide rod 55 to limit the maximum displacement of the guide rod 55. In this embodiment, the guide groove 14 is provided with a limiting rod 56 at the end near the motor 532 along the X direction to limit the maximum displacement of the guide rod 55 in the X direction towards the side near the motor 532.

[0045] It should be noted that this embodiment also provides the working principle of the chain cleaning device for the shredder: the material enters the cavity 11 through the feed inlet 15 and falls onto the conveying section 211. The conveying section 211 conveys the material to the shredding mechanism 3, where it is cut into tobacco shreds. Subsequently, the conveying section 211 conveys the tobacco shreds to the discharge plate 17, where they are discharged to the outside of the shredder body 1. At this time, the annular chain 21 rotates from the conveying section 211 to the return section 212, and the spray base... The nozzle 413 on 412 initially blows away impurities on the surface of the return section 212, the scraper 42 scrapes away the impurities adhering to the surface of the return section 212, the brush 43 cleans the fine impurities remaining on the surface of the return section 212, and the drying unit 44 dries the cleaned return section 212 to ensure that the impurities on the surface of the return section 212 are thoroughly cleaned and kept dry. Then the annular chain 21 turns from the return section 212 to the conveying section 211 for the next conveying operation. During the cleaning process of the cleaning component 4 cleaning the annular chain 21, the second filter screen 52 can separate the solid and liquid impurities that fall from the annular chain 21. The second filter screen 52 only allows liquid to pass through. The tobacco oil and water attached to the tobacco waste can pass through the second filter screen 52 under the action of gravity and enter the collection box 51. The liquid impurities in the collection box 51 can be discharged in sequence through the discharge port 511 and the waste discharge port 16. The tobacco waste is trapped on the second filter screen 52. The tobacco waste trapped on the second filter screen 52 can be pushed to the side of the second filter screen 52 by the pushing action of the push plate 542, which makes it convenient for the operator to collect the tobacco waste on the second filter screen 52 and ensure the recycling of tobacco waste. By setting the second filter screen 52 to separate the solid and liquid of the tobacco waste, it is possible to effectively prevent the tobacco waste from sticking and clogging the collection box 51 with tobacco oil or water.
