Description

Technical Field

[0001] This application relates to the field of sludge drying, and in particular to a sludge drying and cutting machine. Background Technology

[0002] The sludge drying and cutting machine is used to cut sludge into strips. The cut sludge is easier to further dry, dequantify and co-fire, thereby reducing the pollution of sludge to the environment.

[0003] In related technologies, sludge drying and slicing machines use a cutting assembly and a stripping comb to cut the dried sludge. However, because the dried sludge contains impurities such as hair fibers, these impurities easily become entangled on the teeth of the stripping comb, reducing the cutting efficiency of the sludge drying and slicing machine and affecting the continuous formation of strips of dried sludge. The cleanliness of the cutting assembly and the stripping comb directly affects the cutting efficiency and quality of the sludge drying and slicing machine. Currently, to solve this problem, the cutting assembly needs to be frequently disassembled to clean the teeth of the stripping comb, which increases the cleaning time of the sludge drying and slicing machine and affects its working efficiency.

[0004] Therefore, how to design a method to reduce the cleaning time of the dried sludge strip cutter in order to improve its cutting efficiency is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a sludge drying and cutting machine that can reduce the cleaning time of the sludge drying and cutting machine and improve the cutting efficiency of the sludge drying and cutting machine.

[0006] This application provides a sludge drying and strip cutting machine, which adopts the following technical solution: A sludge drying and slicing machine includes a housing defining an installation space; a cutting assembly installed within the housing, the cutting assembly comprising multiple cutting blades arranged sequentially along the width direction of the sludge drying and slicing machine, each cutting blade rotating about its central axis after being driven, each cutting blade having multiple cutting grooves suitable for embedding dried sludge, the multiple cutting grooves being spaced apart along the axial direction of the cutting blade, and at least two cutting blades having their multiple cutting grooves staggered; and multiple stripping components corresponding one-to-one with the multiple cutting blades, arranged along the feeding direction of the sludge drying and slicing machine. Each of the peeling components is located downstream of the corresponding cutter. Each peeling component includes a peeling comb and a first driving member, which is mounted on the housing. The peeling comb has peeling teeth adapted to extend into the corresponding cutter groove. A plurality of cleaning brushes are mounted in the housing, and each cleaning brush corresponds to one of the peeling components. Each cleaning brush is located on the side of the corresponding peeling comb away from the cutter. The first driving member is adapted to drive the peeling comb to rotate about the rotation axis until it abuts against the cleaning brush. The cleaning brush is used to clean the peeling comb.

[0007] By adopting the above technical solution, by adding a cleaning brush and a first driving component to the sludge drying and cutting machine, the first driving component can drive the stripping comb to rotate toward the cleaning brush so that the cleaning brush cleans the stripping comb. Compared with the prior art, the cleaning brush can clean the stripping comb without removing the cutting blade assembly, which can reduce the time required to disassemble the cutting blade assembly and the stripping comb, thereby reducing the cleaning time of the sludge drying and cutting machine and improving the working efficiency of the sludge drying and cutting machine.

[0008] Preferably, the stripping assembly further includes a mounting beam and a drive shaft. The stripping comb is mounted on the mounting beam, which extends along the length of the dried sludge strip cutter. Along the length of the dried sludge strip cutter, the housing has opposing first and second sidewalls. One end of the mounting beam is pivotally connected to the first sidewall. The first drive member is mounted on the outside of the second sidewall. The drive shaft passes through the second sidewall and connects the other end of the mounting beam and the first drive member. The first drive member is adapted to drive the mounting beam to rotate around the central axis of the mounting beam via the drive shaft. The central axis of the mounting beam is configured as the rotation axis of the stripping comb.

[0009] By adopting the above technical solution, by installing a drive shaft, the drive shaft can synchronize the rotation state of the first drive member to the mounting beam. The stripping comb on the mounting beam can extend into the cutting groove. Furthermore, by setting the first sidewall and the second sidewall, the mounting beam can rotate at a preset position. The first drive member can pass through the clearance opening of the second sidewall and connect with the mounting beam.

[0010] Preferably, the sludge drying and slicing machine further includes a locking assembly, which is installed on the outer side of the second sidewall and is used to lock the stripping comb teeth in the cutting groove.

[0011] By adopting the above technical solution, when the mounting beam rotates to the preset position and the stripping comb extends into the cutter, the locking component locks the drive shaft, preventing the drive shaft from rotating, thereby fixing the stripping comb in the preset position. Furthermore, the locking component can release the lock on the drive shaft, allowing the drive shaft to drive the stripping comb to rotate.

[0012] Preferably, the locking and limiting assembly includes a locking bushing and a top support. The locking bushing is sleeved on the outside of the drive shaft and is fixedly connected to the drive shaft. The locking bushing has a locking boss. One end of the top support is fixed to the second side wall, and the other end of the top support is adapted to engage with the locking boss after the stripping comb teeth extend into the cutter groove, so as to restrict the drive shaft from driving the stripping comb to rotate in a direction away from the cutter groove.

[0013] By adopting the above technical solution, when the drive shaft rotates, the drive shaft can drive the locking sleeve to rotate. When the locking boss of the locking sleeve contacts the top support, the locking sleeve cannot continue to rotate. At the same time, the drive shaft fixedly connected to the locking sleeve cannot rotate either, thereby achieving the limiting effect of the locking component on the drive shaft.

[0014] Preferably, the top support is telescopically deformable, and the top support is contracted and deformed to unlock and avoid the locking bushing.

[0015] By adopting the above technical solution, when the top support extends, it can contact the locking sleeve, preventing the drive shaft from rotating. At the same time, the top support can retract, preventing it from contacting the locking sleeve and thus unlocking the stripping comb.

[0016] Preferably, the cleaning brush includes a brush body and a second driving member. The brush body extends along the length of the housing, and the outer peripheral wall of the brush body has a plurality of scraping plates. The scraping plates extend along the radial direction of the brush body and are adapted to press against the stripping comb. The plurality of scraping plates are arranged sequentially along the circumferential direction of the brush body. The second driving member is throttle-connected to the brush body and is used to drive the brush body to rotate around the central axis of the brush body so that the scraping plates clean the stripping comb.

[0017] By adopting the above solution, when cleaning the stripping comb, the stripping comb can press against the scraper plate of the brush body. When the second driving member drives the brush body to rotate, the brush body drives multiple scraper plates to scrape the surface of the stripping comb to remove the debris on the surface of the stripping comb, thereby achieving the purpose of cleaning the stripping comb. Compared with the prior art, by adding a brush body and a second driving member, the second driving member can drive the brush body to drive the scraper plate to clean the stripping comb, reducing the steps of disassembling the cutter group and the stripping comb when cleaning the stripping comb, thereby reducing the time for cleaning the stripping comb and shortening the cleaning time of the stripping comb.

[0018] Preferably, the sludge drying and slicing machine further includes: a controller, which is communicatively connected to both the first drive member and the second drive member. The controller is used to control the first drive member to drive the stripping comb to rotate along a first direction by a first preset angle to press against the scraper plate, and to control the second drive member to drive the brush body to clean the stripping comb, and to control the first drive member to drive the stripping comb to rotate along a second direction by a second preset angle so that the stripping comb teeth extend into the cutting groove.

[0019] By adopting the above scheme, and controlling the first and second drive components through the controller, the technical effect of automatically cleaning the stripping comb of the dried sludge cutting machine can be achieved. This reduces the manual operation required to clean the stripping comb, further reduces the cleaning time of the dried sludge cutting machine, and thus improves the working efficiency of the dried sludge cutting machine. Furthermore, controlling the first and second drive components through the controller can improve the working accuracy of the first and second drive components.

[0020] Preferably, the sludge drying and cutting machine further includes: a position sensor, which is communicatively connected to the controller, the position sensor being disposed near the cutter, the position sensor being triggered when the stripping comb extends into the cutter groove, and the controller being configured to control the first drive to stop working based on the trigger signal of the position sensor.

[0021] By adopting the above scheme, when the stripping comb teeth of the stripping comb extend into the cutter groove, the position sensor sends a trigger signal to the controller. The trigger signal causes the controller to control the first drive component to stop rotating, thereby minimizing the risk of the stripping comb being damaged by squeezing the cutter, and thus further improving the working accuracy of the stripping comb.

[0022] Preferably, the plurality of the first driving elements are all located on the same side of the housing.

[0023] The multiple first drive components are all located on the same side of the housing. Compared with setting the multiple first drive components on different sides of the housing, the overall space occupied by the first drive components in the sludge drying and cutting machine can be reduced, thereby making the structure of the sludge drying and cutting machine more compact.

[0024] Preferably, the edge shape of the cross-section of the cutting groove is an arc.

[0025] By adopting the above scheme, the cutter shapes the dried sludge, making the edge shape of the cross-section of the dried sludge curved. Compared with the prior art, the cutter with curved edge shape can increase the contact area of ​​the outer surface of the dried sludge, which is convenient for subsequent treatment of the dried sludge, and at the same time makes it easier for the dried sludge to fall out of the cutter groove.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Along the feeding direction of the sludge drying and cutting machine, a cleaning brush is installed downstream of the stripping comb. A first driving component allows the stripping comb to rotate. When the stripping comb needs cleaning, the first driving component drives the stripping comb to contact the cleaning brush, enabling the cleaning brush to clean the stripping comb. After cleaning, the first driving component drives the stripping comb away from the cleaning brush and simultaneously drives the stripping comb into the corresponding cutter. Compared to existing technologies, cleaning the stripping comb does not require disassembling the cutter assembly and the stripping comb, thus reducing the difficulty of cleaning the stripping comb and consequently reducing training costs for cleaning personnel. 2. When the sludge drying and cutting machine needs to cut sludge, the controller controls the first drive component to drive the transmission shaft to rotate the stripping comb. Simultaneously, a position sensor detects the rotation position of the stripping comb. When the stripping comb extends into the cutting groove, the controller, through the position signal detected by the position sensor, controls the first drive component to stop rotating. Furthermore, the locking sleeve fitted onto the transmission shaft engages with the top support component to prevent the stripping comb teeth from extending into the cutting groove. When the stripping comb needs cleaning, the top support component retracts, and the first drive component drives the stripping comb to rotate, causing the stripping comb to engage with the scraper plate of the brush body, allowing the scraper plate to clean the stripping comb. Compared to existing technologies, the cleaning work is automatically completed by the sludge drying and cutting machine, shortening the cleaning time and thus improving cleaning efficiency.

[0029] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0030] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0031] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0032] This application discloses a sludge drying and cutting machine 1000, which is used to cut dried sludge into strips. When the dried sludge passes through the sludge drying and cutting machine 1000, the machine shapes the dried sludge and can cut it into segments.

[0033] Reference Figure 1 , Figure 2The sludge drying and slicing machine 1000 includes: a housing 400, a cutting assembly 100, multiple stripping components 200, and multiple cleaning brushes 300. The housing 400 defines an installation space and has a first sidewall 41 and a second sidewall 42. The cutting assembly 100 is installed between the first sidewall 41 and the second sidewall 42 of the housing 400. Along the length of the sludge drying and slicing machine 1000, the first sidewall 41 and the second sidewall 42 of the housing 400 are opposite to each other and spaced apart. The length of the sludge drying and slicing machine 1000 can be defined as follows: Figure 1 The left and right directions in the middle.

[0034] The cutter assembly 100 has multiple cutters 10, which are arranged sequentially along the width direction of the sludge drying and slicing machine 1000. It should be noted that the width direction of the sludge drying and slicing machine 1000 can refer to... Figure 2 The front and back directions in Figure 2 In the illustrated embodiment, the cutter assembly 100 has two cutters 10, namely a first cutter 12 and a second cutter 13. Of course, in other embodiments, the cutter assembly 100 has two or more cutters 10. The present application will now be described with the cutter assembly 100 having two cutters 10.

[0035] Each cutter 10, once driven, rotates around its central axis. Specifically, each cutter 10 can be connected to a drive motor, which drives the cutter 10 to rotate around its central axis. Each cutter 10 has a cutting groove 11, which extends circumferentially and forms a ring structure. Furthermore, the multiple cutting grooves 11 of at least two cutters 10 are staggered. When the cutter group 100 includes two cutters 10, the outer peripheral wall of the first cutter 12 is positioned opposite to the cutting groove 11 of the second cutter 13, and vice versa.

[0036] When the sludge drying and cutting machine 1000 is running, the first cutter 12 and the second cutter 13 rotate along their respective central axes, and the rotation direction of the first cutter 12 is opposite to that of the second cutter 13. Part of the dried sludge can be squeezed by the outer peripheral wall of the first cutter 12 and embedded into the cutting groove 11 of the second cutter 13 to form strip-shaped dried sludge, and another part of the dried sludge can be squeezed by the outer peripheral wall of the second cutter 13 and embedded into the cutting groove 11 of the first cutter 12 to form strip-shaped dried sludge.

[0037] Furthermore, multiple stripping components 200 correspond one-to-one with multiple cutters 10. When there are two cutters 10, one stripping component 200 corresponds to the first cutter 12, and the other stripping component 200 corresponds to the second cutter 13. The stripping component 200 is used to strip the strip-shaped dried sludge out of the cutter groove 11. By discharging the dried sludge from the cutter groove 11, the cutter groove 11 can circulate and compress the dried sludge into a strip-shaped structure.

[0038] Specifically, along the feeding direction of the sludge drying and cutting machine 1000, each stripping component 200 is located downstream of the corresponding cutter 10. The feeding direction of the sludge drying and cutting machine 1000 can be... Figure 2 From top to bottom, each stripping assembly 200 includes a stripping comb 21 with stripping teeth 34 adapted to extend into a corresponding cutting groove 11. When the cutter 10 rotates to transport the dried sludge in the cutting groove 11 to the stripping teeth 34, the stripping teeth 34 scrape the strip-shaped dried sludge out of the cutting groove 11. When the stripping assembly 200 strips the dried sludge, the strip-shaped dried sludge breaks due to the tangential force of the stripping assembly 200, thereby achieving the technical effect of segmenting the strip-shaped dried sludge.

[0039] Furthermore, each stripping assembly 200 also includes a first drive member 22, which is mounted on the housing 400. The first drive member 22 can be a drive motor, and its output end is connected to the stripping comb 21. The first drive member 22 is adapted to drive the stripping comb 21 to rotate around the rotation axis.

[0040] Along the feeding direction of the sludge drying and cutting machine 1000, a cleaning brush 300 is installed on the downstream side of the stripping component 200, and multiple cleaning brushes 300 correspond one-to-one with multiple stripping components 200. When the stripping comb 21 of the stripping component 200 needs to be cleaned, the first driving component 22 connected to the stripping component 200 drives the stripping comb 21 to rotate, so that the stripping comb 21 and the cleaning brush 300 press against each other. The cleaning brush 300 can scrub the surface of the stripping comb 21 so that hair fibers and other debris are removed from the stripping comb teeth 34, thereby achieving the technical effect of cleaning the stripping comb 21 by the cleaning brush 300.

[0041] After the stripping comb 21 is cleaned, the first driving member 22 drives the stripping comb 21 to rotate in the opposite direction. The first driving member 22 can make the stripping comb 21 rotate again until the stripping comb teeth 34 extend into the corresponding cutting groove 11.

[0042] Therefore, by adding a cleaning brush 300 and a first driving member 22 to the sludge drying and cutting machine 1000, the first driving member 22 can drive the stripping comb 21 to rotate toward the cleaning brush 300 so that the cleaning brush 300 cleans the stripping comb 21. Furthermore, the cleaning brush 300 can clean the stripping comb 21 without removing the cutting assembly 100, which can reduce the time required to disassemble the cutting assembly 100 and the stripping comb 21, thereby reducing the cleaning time of the sludge drying and cutting machine 1000 and improving the working efficiency of the sludge drying and cutting machine 1000.

[0043] For example in Figure 2 In the illustrated embodiment, multiple first driving members 22 are all disposed on the outer side of the second sidewall 42 of the housing 400. Of course, in other embodiments, multiple first driving members 22 are all disposed on the outer side of the first sidewall 41 of the housing 400. By disposing multiple first driving members 22 on the same side of the housing 400, compared to disposing multiple first driving members 22 on different sides of the housing 400, this arrangement facilitates the arrangement of multiple first driving members 22 on the housing 400, thereby reducing the impact on the drying sludge cutting machine 1000. Figure 1 The left-right dimension length can reduce the overall space occupied by the first drive component 22 in the sludge drying and cutting machine 1000, thereby making the structure of the sludge drying and cutting machine 1000 more compact.

[0044] Reference Figures 1-3 In some embodiments of this application, the stripping assembly 200 may be provided with a mounting beam 23 and a drive shaft 24. The stripping comb 21 is mounted on the mounting beam 23, which provides a mounting position for the stripping comb 21. The mounting beam 23 is along the length direction of the sludge drying and cutting machine 1000 (the length direction is...). Figure 1 Extending in the left and right directions, the right end of the installation beam 23 (i.e., Figure 1 The right end of the mounting beam 23 is pivotally connected to the first side wall 41 of the housing 400, and the left end of the mounting beam 23 (i.e. Figure 1 The left end of the drive shaft 24 is fixedly connected to the drive shaft 24, which passes through the second side wall of the housing 400 and is connected between the other end of the mounting beam 23 and the first drive member 22.

[0045] Therefore, the first driving member 22 can drive the mounting beam 23 to rotate around the central axis of the mounting beam 23 through the transmission shaft 24. When the mounting beam 23 rotates, it drives the stripping comb 21 to rotate around the central axis of the mounting beam 23. In other words, the central axis of the mounting beam 23 is constructed as the rotation axis of the stripping comb 21. By setting the transmission shaft 24 and the mounting beam 23 between the stripping comb 21 and the first driving member 22, the technical effect of transmission connection between the stripping comb 21 and the first driving member 22 is achieved. Furthermore, the stripping comb 21 can be installed inside the drying sludge strip cutter 1000 through the mounting beam 23.

[0046] Meanwhile, the second sidewall 42 of the housing 400 is provided with a clearance opening. The output end of the first drive member 22 extends into the drive shaft 24 from the left end of the drive shaft 24 and is fixedly connected to the drive shaft 24, so that the first drive member 22 is connected to the drive shaft 24 for transmission. When the stripping comb 21 is stuck in the cutter groove 11 and the mounting beam 23 cannot rotate, since the part of the output shaft of the first drive member 22 that extends into the drive shaft 24 is cylindrical, the output end of the first drive member 22 can continue to rotate in the groove of the drive shaft 24, thereby preventing the first drive member 22 from being damaged. Furthermore, the other end of the drive shaft 24 passes through the clearance opening and is fixedly connected to the mounting beam 23. When the stripping comb 21 needs to be flipped, the first drive member 22 drives the drive shaft 24 and the mounting beam 23 to flip the stripping comb 21.

[0047] Reference Figure 5 In some embodiments of this application, the sludge drying and cutting machine 1000 further includes a locking component 201, which is installed on the outside of the second side wall 42 of the housing 400. When the sludge drying and cutting machine 1000 scrapes out the dried sludge in the cutting groove 11 using the peeling component 200, the peeling component 200 flips so that the peeling comb 34 extends into the corresponding cutting groove 11. By locking the peeling component 201, the peeling component 200 can be locked, which can prevent the peeling comb 34 from being pushed out of the cutting groove 11 by the dried sludge in the cutting groove 11. This helps to avoid the dried sludge remaining in the cutting groove 11, which can improve the forming quality of the strip-shaped dried sludge and improve the efficiency of the sludge drying and cutting machine 1000 in processing dried sludge.

[0048] Furthermore, when the stripping comb 34 extends into the cutter groove 11, the first drive member 22 itself has a locking function, and at the same time the locking component 201 locks the drive shaft 24, so that the mounting beam 23 fixedly connected to the drive shaft 24 cannot rotate while the drive shaft 24 cannot rotate. Thus, when cutting dried sludge into strips, the stripping comb 34 is prevented from being pushed out of the cutter groove 11 by the dried sludge.

[0049] Furthermore, referring to Figure 5 The locking assembly 201 includes a locking bushing 25 and a top support 26. The top support 26 is fixed to the outside of the second side wall 42 of the housing 400. The locking bushing 25 is sleeved on the outside of the drive shaft 24 and the drive shaft 24 is fixedly connected to the locking bushing 25. When the drive shaft 24 rotates, it can drive the locking bushing 25 to rotate with it.

[0050] The locking bushing 25 has a locking boss 27. When the sludge drying machine 1000 cuts the dried sludge and the stripping comb 34 of the stripping comb 21 extends into the cutting groove 11 of the cutter 10, the locking boss 27 and the top support 26 engage in a stop-and-holding cooperation. The top support 26 can interfere with the locking boss 27. The top support 26 can restrict the locking bushing 25 from rotating relative to the top support 26. Thus, the locking bushing 25 can restrict the rotation of the drive shaft 24. The drive shaft 24 can restrict the stripping comb 21 from rotating around the central axis of the mounting beam 23 in a direction away from the cutting groove 11. That is, the locking assembly 201 can indirectly restrict the rotation of the stripping comb 21 through the drive shaft 24, thereby achieving the technical effect of preventing the stripping comb teeth 34 from coming out of the cutting groove 11.

[0051] Furthermore, referring to Figure 5 The top support 26 can extend and deform. Specifically, the top support 26 can be constructed as a cylinder, hydraulic cylinder, or electric strut, etc. When the sludge drying and cutting machine 1000 cuts the sludge, the top support 26 extends and its length increases. The top support 26 and the locking boss 27 abut against the locking peeling assembly 200. Meanwhile, the preset flip angle range of the stripping comb 21 can be set to 0°~180°. When the top support 26 locks the stripping assembly 200, the flip angle of the stripping comb 21 is set to 0°. When the drying sludge cutting machine 1000 needs to use the cleaning brush 300 to clean the stripping comb 21, the top support 26 retracts and its length decreases. This allows the top support 26 to separate from the locking bushing 25 and minimizes interference between the locking boss 27 and the top support 26 when the locking bushing 25 rotates. The top support 26 no longer locks the stripping assembly 200, thus allowing the stripping comb 21 to flip within the preset flip angle range, achieving the technical effect of the locking assembly 201 unlocking the stripping comb 21.

[0052] Reference Figure 6 In some embodiments of this application, the cleaning brush 300 includes a brush body 31 and a second driving member 32, wherein the brush body 31 is along the length direction of the housing 400 (the length direction is...). Figure 1 The brush body 31 can be extended in the left and right directions. Furthermore, there can be multiple brush bodies 31, which are arranged sequentially along the length of the housing 400.

[0053] Each brush body 31 has multiple scraping plates 33 on its outer peripheral wall. The scraping plates 33 extend radially along the brush body 31, and the multiple scraping plates 33 are arranged sequentially along the circumferential direction of the brush body 31. The second driving member 32 is connected to the brush body 31 in a driving connection. The second driving member 32 can be a drive motor. In some embodiments, the second driving member 32 is directly fixedly connected to the brush body 31. In other embodiments, a reducer is connected between the second driving member 32 and the brush body 31, and the power generated by the second driving member 32 can be transmitted to the brush body 31 through the reducer. The second driving member 32 is adapted to drive the brush body 31 to rotate around its central axis. When the brush body 31 rotates, it drives the scraping plates 33 to rotate around the central axis of the brush body 31.

[0054] When the stripping comb 21 needs to be cleaned, the stripping comb 21 presses against the scraper plate 33, the second driving member 32 drives the brush body 31 to rotate, and multiple scraper plates 33 circulate to scrape the surface of the stripping comb 21 to remove hair fibers and other debris from the surface of the stripping comb 21, thereby achieving the technical effect of cleaning the stripping comb 21 by the cleaning brush 300.

[0055] Therefore, by cooperating with the brush body 31 and the second drive member 32, the steps of removing the cutter assembly 100 and the stripping comb 21 during cleaning of the stripping comb 21 are reduced, thereby reducing the time required to clean the stripping comb 21. In some embodiments, the scraper plate 33 can be made of copper. This arrangement minimizes friction between the scraper plate 33 and the stripping comb 21 during cleaning, thus reducing wear or damage to the stripping comb 21.

[0056] In some embodiments of this application, the sludge drying and cutting machine further includes a controller. The controller is communicatively connected to both the first drive member 22 and the second drive member 32. The controller can control the operation of the first drive member 22 and the second drive member 32 through signals. When the stripping comb 21 needs to be cleaned, the controller controls the first drive member 22 to drive the stripping comb 21 to rotate along the first direction by a first preset angle, so that the scraper 33 can press against the stripping comb 21. The controller also controls the second drive member 32 to rotate so as to drive the brush body 31 to clean the stripping comb 21.

[0057] Furthermore, after the stripping comb 21 has finished cleaning, the controller controls the second drive component 32 to stop rotating. Simultaneously, the controller controls the first drive component 22 to drive the stripping comb 21 to rotate along the second direction by a second preset angle, thereby causing the stripping comb teeth 34 to extend into the cutting groove 11. It should be noted that the first and second directions of rotation of the stripping comb 21 only represent opposite rotation directions; the specific rotation direction of the stripping comb 21 can be set according to actual conditions. Both the first and second preset angles can be set according to the actual structure of the dried sludge strip cutter 1000. In some embodiments, the first and second preset angles are the same.

[0058] By controlling the first drive component 22 and the second drive component 32, the sludge drying and cutting machine 1000 can automatically clean the stripping comb 21. This reduces the manual operation required to clean the stripping comb 21, further reducing the cleaning time of the sludge drying and cutting machine 1000 and thus improving its working efficiency. Furthermore, the controller improves the working accuracy of the first drive component 22 and the second drive component 32. After cleaning the stripping comb 21, maintenance personnel do not need to calibrate the flipping angle of the stripping comb 21 when it enters the cutting groove 11, further improving the working efficiency of the sludge drying and cutting machine 1000.

[0059] In some embodiments of this application, the sludge drying and cutting machine 1000 further includes a position sensor, which is communicatively connected to the controller and installed close to the cutter 10. The position sensor can identify the position of the stripping comb 21. When the stripping comb 21 is cleaned, the first drive member 22 drives the stripping comb 21 to flip. When the stripping comb 21 extends into the cutter 10, the position sensor identifies the position of the stripping comb 21 and is triggered. The position sensor can generate a trigger signal. After receiving the trigger signal, the controller controls the first drive member 22 to stop working, thereby preventing the stripping comb teeth 34 from being squeezed in the cutter groove 11, and thus preventing the stripping comb 21 from being damaged by pressure as much as possible. By setting the position sensor, the working accuracy of the stripping comb teeth 34 can be further improved.

[0060] Reference Figure 8 In some embodiments of this application, the edge shape of the cross-section of the cutting groove 11 is arc-shaped. When the dried sludge is embedded in the cutting groove 11, the dried sludge is squeezed by the cutter 10 and the cutting groove 11. The cutter 10 and the cutting groove 11 make the edge shape of the cross-section of the dried sludge strip arc-shaped. Compared with the prior art, the outer surface of the dried sludge with the edge shape of the cross-section arc-shaped has a larger contact area, which can improve the processing efficiency of the dried sludge in subsequent processing, thereby further shortening the processing time of the dried sludge. In addition, the strip-shaped dried sludge with the edge shape of the cross-section arc-shaped is easier to detach from the cutter 10, which can reduce the sludge residue in the cutting groove 11, thereby reducing the cleaning frequency of the strip comb 21.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
