Description

Technical Field

[0001] This application relates to the field of cutting device technology, and in particular to a cutting device and its control method. Background Technology

[0002] Conveyor belts are a common component in conveyor systems. During installation, the joints of the conveyor belt need to be cut to ensure a smooth surface, facilitating subsequent connection of the belt.

[0003] Currently, most common conveyor belts are steel cord conveyor belts. When cutting steel cord conveyor belts, it is usually necessary to use fixed equipment for cutting, and then transport the conveyor belt to the installation position after cutting. This is labor-intensive. If the conveyor belt is transported to the installation position and then cut with a handheld cutting device, it is more dangerous and does not improve the safety of conveyor belt cutting. Summary of the Invention

[0004] In view of this, the present application aims to provide a cutting device to improve safety during conveyor belt cutting.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A cutting device includes a base frame, a clamping part and a moving part disposed on the base frame, and a cutting part disposed on the moving part; The clamping part can hold the base frame on the conveyor belt, and a cutting groove extending along the length direction of the base frame is formed on the base frame. The moving part can drive the cutting part to reciprocate within the cutting groove to cut the conveyor belt.

[0006] Furthermore, the cutting part includes a first driving member disposed on the moving part, and a cutting saw blade that is pulsatorically connected to the first driving member; the first driving member is capable of driving the cutting saw blade to rotate, and a portion of the cutting saw blade is located in the cutting groove.

[0007] Furthermore, the cutting part also includes a protective cover disposed on the moving part, the protective cover covering the cutting saw blade.

[0008] Furthermore, a water tank is provided on the base frame, the water tank is located below the cutting groove, and part of the cutting saw blade extends through the cutting groove into the water tank.

[0009] Furthermore, a connector is provided between the base frame and the clamping part, the connector being a ring surrounding the cutting groove; a connecting groove is formed on the connector, the connecting groove connecting the cutting groove and the water tank.

[0010] Furthermore, the moving part includes a second driving member disposed on the base frame, a lead screw that is pulsatorically connected to the second driving member, and a slide screwed onto the lead screw; the second driving member can drive the lead screw to rotate so that the slide can reciprocate along the lead screw.

[0011] Furthermore, the base frame includes a first plate, a second plate disposed above the first plate, and connecting plates disposed on both sides of the first plate along the length of the base frame; the connecting plates are connected between the first plate and the second plate.

[0012] Furthermore, it also includes a spray section; the spray section includes a spray head disposed on the base frame, and the spray surface of the spray head is arranged facing the cutting saw blade.

[0013] Compared with related technologies, this application has the following advantages: (1) The cutting device described in this application facilitates the arrangement of the clamping part, the moving part and the cutting part by setting the base frame. The clamping part facilitates the arrangement of the cutting device on the conveyor belt. Through the cooperation of the clamping part and the moving part, the cutting end of the cutting part can easily cut the conveyor belt along the cutting groove. Furthermore, by setting the cutting part on the moving part, the cutting part can change the cutting position as the moving part moves, which helps to improve the cutting efficiency of the cutting device in cutting the conveyor belt. In addition, manual cutting operation is avoided during the cutting process, which improves the cutting safety of the conveyor belt.

[0014] (2) The first driving component facilitates the rotation of the cutting saw blade. The cutting saw blade facilitates the formation of the cutting end and the cutting of the conveyor belt. The structure is simple and the cutting part is easy to arrange.

[0015] (3) By setting up a protective cover, the saw blade can be covered under the protective cover, reducing the impact of the cutting saw blade on the nearby structure, and thus improving the safety of the cutting device during use.

[0016] (4) By setting up a water tank, cooling water can be arranged in the water tank, and the cutting saw blade can be immersed in the cooling water. This can cool the cutting saw blade during the cutting process, reduce sparks and dust during the cutting process, and prevent the cutting saw blade from overheating, which is conducive to design and implementation.

[0017] (5) A connecting groove is formed between the water tank and the cutting groove through the connecting parts between the base frame and the clamping part, so that the liquid level of the cooling water in the water tank is raised to the top of the cutting groove, so that the cutting end of the cutting saw blade can be immersed in the cooling water when it is cutting, which better reduces the sparks and dust in the cutting process and is conducive to design and implementation.

[0018] (6) The setting of the second driving component, the lead screw and the slide connected to the lead screw makes it easy to adjust the position of the cutting part. Furthermore, the coordinated operation of the lead screw and the slide connected to the lead screw results in a simple structure, accurate position adjustment, and facilitates design and implementation.

[0019] (7) By making the base frame include the first plate, the second plate and the connecting plate, the structure is simple and has good structural strength, which facilitates the arrangement of the moving part, the clamping part and the cutting part, and helps the design and implementation.

[0020] (8) By setting the spray section and making the spray surface of the spray head face the cutting saw blade, the smoke and sparks generated during the cutting process can be reduced better, and the cutting saw blade can be cooled to prevent it from overheating during the cutting process, which is conducive to the design and implementation.

[0021] Another object of this application is to provide a control method for a cutting device, for controlling the cutting device as described above, including: A cutting line is set on the conveyor belt; Align the cutting groove with the cutting line and operate the clamping part to clamp the base frame onto the conveyor belt; The cutting unit is activated, and the moving unit is driven to move the cutting unit along the cutting line within the cutting groove; Once the conveyor belt disconnects, the cutting process is complete.

[0022] Furthermore, when the cutting device becomes stuck, it also includes: Stop the cutting section and retract the moving section; Increase the cutting power of the cutting section and drive the moving section to refeed; When the cutting part passes the jammed part, the cutting power of the cutting part is reduced, and cutting continues; If the cutting part gets stuck again, stop the cutting part and retract the moving part; Based on the increased cutting power of the cutting section, the cutting power is increased again, and the moving section is driven to feed again.

[0023] The control method for the cutting device described in this application is used to control the cutting device as described above. Compared with the prior art, it has the same beneficial effects as the cutting device as described above, so it will not be described again here. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a cutting device for cutting conveyor belts. It is mainly used to cut a flat surface at the end of the conveyor belt to facilitate connection during the installation of the conveyor belt. The cutting device in this embodiment, with its innovative structural design, can improve the cutting efficiency of the conveyor belt.

[0032] In related technologies, conveyor belts are a common structural element in conveying devices. During installation, the joints of the conveyor belt need to be cut to ensure a smooth surface, facilitating subsequent connection of the belt.

[0033] Currently, most common conveyor belts are steel cord conveyor belts. When cutting steel cord conveyor belts, it is usually necessary to use fixed equipment for cutting, and then transport the cut conveyor belt to the installation position. This is labor-intensive. If the conveyor belt is transported to the installation position and then cut with a handheld cutting device, usually an angle grinder, there is a risk of chipping during the use of the angle grinder, which is quite dangerous and does not improve the safety of conveyor belt cutting.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the cutting device in this embodiment combines... Figures 1 to 4 As shown, the overall design includes a base frame 1, a clamping part 2 and a moving part 3 provided on the base frame 1, and a cutting part 4 provided on the moving part 3.

[0035] The clamping part 2 can hold the base frame 1 on the conveyor belt. The base frame 1 has a cutting groove 5 that extends along the length of the base frame 1. The cutting part 4 has a cutting end that can extend into the cutting groove 5. The moving part 3 can drive the cutting part 4 to move back and forth in the cutting groove 5 to cut the conveyor belt.

[0036] At this time, as set up as above, the base frame 1 facilitates the arrangement of the clamping part 2, the moving part 3 and the cutting part 4. The clamping part 2 facilitates the placement of the cutting device on the conveyor belt. Through the coordinated operation of the clamping part 2 and the moving part 3, the cutting end of the cutting part 4 can easily cut the conveyor belt along the cutting groove 5. Furthermore, by placing the cutting part 4 on the moving part 3, the cutting part 4 can change its cutting position as the moving part 3 moves, which helps to improve the cutting efficiency of the cutting device in cutting the conveyor belt and avoids manual cutting operations, thus improving the safety of conveyor belt cutting.

[0037] Based on the above general introduction, specifically, the cutting device in this embodiment is assembled on the conveyor belt by the clamping part 2, and cuts by the cutting part 4 corresponding to the cutting position on the conveyor belt.

[0038] The clamping part 2 includes a clamping plate 201 located below the base frame 1, and clamping holes 202 located on the clamping plate 201 and the base frame 1. The clamping plate 201 is provided corresponding to the clamping holes 202 on the base frame 1, and has internal threads.

[0039] When clamping with clamping part 2, clamping part 2 can be arranged below the conveyor belt to be cut, and the cutting device can be installed on the conveyor belt by passing bolts through the clamping holes 202 on the base frame 1 and clamping plate 201.

[0040] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, include a cutting section 4 comprising a first drive member 401 disposed on a moving section 3, and a cutting saw blade 402 that is pulsatorically connected to the first drive member 401.

[0041] The first driving member 401 can drive the cutting saw blade 402 to rotate, and part of the cutting saw blade 402 is located in the cutting groove 5.

[0042] It is understandable that the first driving component 401 facilitates the rotation of the cutting saw blade 402, and the cutting saw blade 402 facilitates the formation of the cutting end and the cutting of the conveyor belt. The structure is simple and the arrangement of the cutting section 4 is convenient.

[0043] In a specific implementation, the first driving component 401 may be, for example, a variable frequency motor. The power output end of the first driving component 401 is connected to the cutting saw blade 402 and can drive the cutting saw blade 402 to rotate, thereby cutting the conveyor belt.

[0044] In actual implementation, the cutting saw blade 402 can be, for example, a cold cutting saw blade with trapezoidal flat teeth. The number of teeth on the saw blade can be, for example, 40T, 60T, etc. The relevant parameters are related to the cutting requirements of the cutting unit 4. In actual implementation, it is necessary to set them accordingly according to the cutting requirements of the cutting unit 4.

[0045] In addition, the cutting unit 4 may include a cutting controller, which is configured to receive a control signal and adjust the rotational speed of the first drive member 401 to change the cutting power of the cutting unit 4.

[0046] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, include a protective cover 6 disposed on the moving part 3, which covers the cutting saw blade 402.

[0047] Understandably, by setting up the protective cover 6, the cutting saw blade 402 can be covered under the protective cover 6, reducing the impact of the cutting saw blade 402 on the surrounding structure, and thus improving the safety of the cutting device during use.

[0048] In practical implementation, the protective cover 6 can be arranged in a U-shape and covered on the cutting saw blade 402. When the cutting saw blade 402 is cutting, the cutting debris and sparks generated during the cutting process can be blocked by the protective cover 6 to prevent them from splashing into the external environment.

[0049] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, have a water tank 7 on the base frame 1, the water tank 7 being located below the cutting groove 5, and a portion of the cutting saw blade 402 extending through the cutting groove 5 into the water tank 7.

[0050] It is understandable that by setting up the water tank 7, cooling water can be arranged in the water tank 7, and part of the cutting saw blade 402 can be immersed in the cooling water. This can cool the cutting saw blade 402 during the cutting process, reduce sparks and dust during the cutting process, and prevent the cutting saw blade 402 from overheating, which is beneficial to the design and implementation.

[0051] In practice, the water tank 7 extends along the length of the base frame 1 and corresponds to the travel of the cutting saw blade 402. The end of the water tank 7 is provided with an inlet and an outlet, which are connected to an external water supply device to allow cooling water to circulate in the water tank 7.

[0052] Specifically, the water tank 7 is formed on the clamping plate 201 and is positioned corresponding to the cutting groove 5. The end of the cutting saw blade 402 can pass through the cutting groove 5 and extend into the water tank 7 to cool the cutting teeth of the cutting saw blade 402 with cooling water.

[0053] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a connector 10 between the base frame 1 and the clamping part 2.

[0054] The connector 10 is a ring around the cutting groove 5, and a connecting groove 1001 is formed on the connector 10, which connects the cutting groove 5 and the water tank 7.

[0055] It is understandable that by using the connector 10 between the base frame 1 and the clamping part 2, a connecting groove 1001 is formed between the water tank 7 and the cutting groove 5, so that the liquid level of the cooling water in the water tank 7 is raised to the top of the cutting groove 5, so that the cutting end of the cutting saw blade 402 can be immersed in the cooling water when it is cutting, which better reduces sparks and dust during the cutting process and facilitates design and implementation.

[0056] In specific implementation, the connector 10 can be, for example, a rubber block. The top and bottom of the connector 10 are provided with grooves. Correspondingly, the base frame 1 and the clamping part 2 are provided with protrusions. The protrusions can be inserted into the grooves to constrain the position of the connector 10.

[0057] In addition, to facilitate the assembly of the conveyor belt, a groove matching the conveyor belt is provided on the connector 10. When the conveyor belt is assembled on the cutting device, the conveyor belt is located in the groove on the connector 10. At this time, when cooling water flows in the water tank 7, the conveyor belt is submerged in the cooling water, so that the cutting position of the cutting saw blade 402 on the conveyor belt is located in the cooling water, which can form an underwater cutting method.

[0058] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, include a moving part 3 including a second drive member 301 disposed on a base frame 1, a lead screw 302 drivenly connected to the second drive member 301, and a slide 303 screwed onto the lead screw 302.

[0059] The second driving member 301 can drive the lead screw 302 to rotate so that the slide 303 can reciprocate along the lead screw 302.

[0060] It is understandable that the arrangement of the second drive component 301, the lead screw 302, and the slide 303 screwed onto the lead screw 302 facilitates the adjustment of the position of the cutting part 4. Furthermore, the coordinated operation of the lead screw 302 and the slide 303 screwed onto the lead screw 302 results in a simple structure, accurate position adjustment, and facilitates design and implementation.

[0061] In specific implementation, the second driving member 301 can be a servo motor, the lead screw 302 can be a ball screw 302, and the cutting part 4 is mounted on the slide table 303 so that the slide table 303 can be driven by the second driving member 301 to move the cutting part 4 along the cutting path.

[0062] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, include a base frame 1 including a first plate 101, a second plate 102 disposed above the first plate 101, and connecting plates 103 disposed on both sides of the first plate 101 along the length direction of the base frame 1, with the connecting plates 103 connecting between the first plate 101 and the second plate 102.

[0063] It is understandable that by making the base frame 1 include the first plate 101, the second plate 102 and the connecting plate 103, the structure is simple and has good structural strength, which facilitates the arrangement of the moving part 3, the clamping part 2 and the cutting part 4, and thus helps the design and implementation.

[0064] In specific implementation, the first plate 101 and the second plate 102 can both be made of aluminum profiles, for example. The connecting plate 103 is connected to both sides of the first plate 101 and the second plate 102 along the length of the base frame 1, and the connection between the connecting plate 103 and the first plate 101 and the second plate 102 can be provided with a corresponding reinforcing structure (such as a reinforcing rib). The connection between the first plate 101, the second plate 102 and the connecting plate 103 can be, for example, a screw connection.

[0065] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a plurality of casters 8 below the base frame 1.

[0066] Understandably, the multiple casters 8 installed under the base frame 1 facilitate the movement of the cutting device, reduce the labor intensity of moving the cutting device, and help move the cutting device.

[0067] In practical implementation, in order to facilitate the movement of the cutting device, in addition to the casters 8, a detachable handle can also be installed on the base frame 1. By holding the handle, the cutting device can be moved on site, and the handle can be removed when the cutting device needs to be used.

[0068] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may include, for example, a spray section 9. The spray section 9 includes a spray head 901 disposed on the base frame 1, the spray surface of the spray head 901 being disposed facing the cutting saw blade 402.

[0069] It is understandable that by setting up the spray section 9 and making the spray surface of the spray head 901 face the cutting saw blade 402, the smoke and sparks generated during the cutting process can be reduced better, and the cutting saw blade 402 can be cooled to prevent it from overheating during the cutting process, which is conducive to the design and implementation.

[0070] In practical implementation, the spray heads 901 are mounted on the protective cover 6, and spray heads 901 are provided on both sides of the protective cover 6 along the cutting direction of the cutting section. Each spray head 901 sprays water towards the cutting saw blade 402. The spray heads 901 are connected to an external water supply through connecting pipes. When the cutting device is in use, the spray heads 901 can be used in conjunction with the water tank 7 to cool the cutting saw blade 402 together, thereby reducing the smoke and sparks generated during the cutting process.

[0071] It is worth noting that, regarding the cutting device of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 4 As shown, it may include, for example, a base frame 1.

[0072] The base frame 1 includes a first plate 101, a second plate 102 disposed above the first plate 101, and connecting plates 103 disposed on both sides of the first plate 101 along the length of the base frame 1. The connecting plates 103 are connected to the first plate 101 and the second plate 102. Universal wheels 8 are respectively provided at the four corners of the bottom of the first plate 101.

[0073] The second plate 102 is provided with a movable part 3, which includes a second driving member 301 on the connecting plate 103, a lead screw 302 on the second plate 102, and a slide 303 screwed onto the lead screw 302. The clamping part 2 is provided on the slide 303 and includes a first driving member 401 and a cutting saw blade 402 driven to rotate by the first driving member 401.

[0074] The first plate 101 is provided with a cutting groove 5, and the cutting end of the cutting saw blade 402 extends into the cutting groove 5. The clamping part 2 includes a clamping plate 201 located below the first plate 101, and clamping holes 202 respectively provided on the first plate 101 and the clamping plate 201. The clamping holes 202 on the first plate 101 are correspondingly provided with the clamping holes 202 on the clamping plate 201, and each clamping hole 202 is provided with a thread.

[0075] The clamping plate 201 is provided with a water tank 7 at the position corresponding to the cutting groove 5. The end of the cutting saw blade 402 extends into the water tank 7 and can be cooled by the cooling water flowing in the water tank 7. A connector 10 is provided between the first plate 101 and the clamping plate 201. A connecting groove 1001 is formed on the connector 10 to connect the water tank 7 and the cutting groove 5.

[0076] In the preferred embodiment of the above cutting device, the specific configuration and arrangement of the base frame 1, the moving part 3, the clamping part 2, etc. can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the base frame 1, the moving part 3, and the clamping part 2, etc., can also be referred to the description in the above exemplary embodiments.

[0077] The cutting device of this embodiment adopts the above design. The base frame 1 facilitates the arrangement of the clamping part 2, the moving part 3 and the cutting part 4. The clamping part 2 facilitates the placement of the cutting device on the conveyor belt. Through the cooperation of the clamping part 2 and the moving part 3, the cutting end of the cutting part 4 can easily cut the conveyor belt along the cutting groove 5. Furthermore, by placing the cutting part 4 on the moving part 3, the cutting part 4 can change its cutting position as the moving part 3 moves, which helps to improve the cutting efficiency of the cutting device in cutting the conveyor belt.

[0078] A second aspect of this application provides a control method for a cutting device, which is used to control the cutting device in the first aspect of this application, in conjunction with... Figures 1 to 5 As shown, the control method includes the following steps: Step S1: Set the cutting line on the conveyor belt.

[0079] In step S1, when setting the cutting line on the conveyor belt, it is necessary to make corresponding settings according to the requirements of the conveyor belt docking. Usually, the docking surface of the conveyor belt is set as a plane.

[0080] Step S2: Align the cutting groove 5 with the cutting line and operate the clamping part 2 to clamp the base frame 1 onto the conveyor belt.

[0081] In step S2, the cutting groove 5 is aligned with the cutting line, so that the cutting end of the cutting part 4 can move along the cutting line. When the clamping part 2 is clamped on the conveyor belt, the clamping plate 201 is arranged below the conveyor belt, and the base frame 1 is connected to the clamping part 2 and fastened by bolts.

[0082] Step S3: Start the cutting part 4 and drive the moving part 3 to move the cutting part 4 along the cutting line in the cutting groove 5.

[0083] In step S3, when the cutting unit 4 is started, the rotation speed of the cutting unit 4 can be set in the range of 900-1000 r / min, and the moving speed of the moving unit 3 can be set in the range of 30-35 mm / s. After the cutting end of the cutting unit 4 has finished cutting the rubber part, when it is detected that the cutting unit 4 is cutting the steel wire rope core, the moving speed of the moving unit 3 is reduced to 3-7 mm / s, and the rotation speed of the cutting unit 4 is adjusted to 1400-1500 r / min. After the cutting unit 4 has finished cutting the steel wire rope core part, the rotation speed and moving speed are restored to the corresponding parameters for cutting the rubber part.

[0084] One method for detecting the material being cut by the cutting section 4 is to obtain the current of the first driving member 401. When the cutting section 4 cuts to the core of the steel wire rope, the torque of the first driving member 401 increases, and the current of the first driving member 401 increases. At this time, it can be determined that the cutting has reached the core of the steel wire rope. When the cutting section 4 has finished cutting the core of the steel wire rope and is cutting the rubber material, the torque of the first driving member 401 decreases, and the current of the first driving member 401 also decreases. At this time, it can be determined that the cutting has been completed.

[0085] It is worth noting that the rotational speed range of the cutting section 4 is inversely proportional to the moving speed range of the moving section 3. That is, as the rotational speed of the cutting section 4 increases within its rotational speed range, the moving speed of the moving section 3 decreases accordingly. In other words, when cutting the rubber section, the rotational speed is lower and the moving speed is higher. Conversely, as the current of the first driving member 401 gradually increases, the rotational speed of the cutting section 4 gradually increases, while the moving speed of the moving section 3 gradually decreases.

[0086] Furthermore, if jamming occurs when the moving part 3 drives the cutting part 4 to move within the cutting groove 5, the corresponding operation shall be performed in accordance with steps S10 to S50 of the cutting device jamming procedure in this embodiment.

[0087] Step S4: Once the conveyor belt disconnects, the cutting is complete.

[0088] In step S4, the disconnection of the conveyor belt indicates that the cutting operation of the conveyor belt has been completed, thus the cutting is finished.

[0089] When the cutting device jams, the control method also includes: Step S10: Stop the cutting part 4 and retract the moving part 3.

[0090] In step S10, if the cutting device jams, the cutting section 4 must be stopped first to avoid other problems during its retraction. The retraction distance of the cutting section 4 can be, for example, 1-2 mm, just enough to disengage the cutting end of the cutting section 4 from the conveyor belt.

[0091] It is worth noting that when the rotation speed of the cutting part 4 increases to the preset rotation speed range, if the current of the first driving member 401 continues to increase beyond the current value corresponding to the normal rotation speed range, it is determined that the cutting device is stuck, and at this time the moving part 3 is driven to retract.

[0092] Step S20: Increase the cutting power of the cutting unit 4 and drive the moving unit 3 to re-feed.

[0093] In step S20, increasing the cutting power of the cutting unit 4 means increasing the rotation speed of the cutting saw blade 402. The cutting speed of the cutting saw blade 402 is increased accordingly based on the cutting speed at which the current cutting action is performed. The range of the increased speed is, for example, 300-500 r / min.

[0094] In addition, when adjusting the cutting power of the cutting section 4, the moving speed of the moving section 3 is also adjusted. The moving speed of the moving section 3 can be adjusted accordingly according to the moving speed and rotation speed matching relationship described in step S3.

[0095] Step S30: When the cutting part 4 passes through the jammed part, reduce the cutting power of the cutting part 4 and continue cutting.

[0096] In step S30, reducing the cutting power of the cutting unit 4 means reducing the rotation speed of the cutting saw blade 402 to the corresponding cutting speed during normal cutting.

[0097] Step S40: If the cutting part 4 gets stuck again, stop the cutting part 4 and retract the moving part 3.

[0098] In step S40, if the cutting part gets stuck again after passing the stuck part, step S10 is followed to stop the cutting part 4 and cause the moving part 3 to retract.

[0099] Step S50: Based on the increased cutting power of the cutting unit 4, the cutting power is increased again, and the moving unit 3 is driven to feed again.

[0100] In step S50, the increase in cutting power of the cutting section 4 can be adjusted according to the adjustment method described in step S20.

[0101] It is worth noting that in actual implementation, when jamming occurs frequently, it proves that the cutting saw blade 402 of the cutting section 4 has aged, and the staff needs to replace and maintain the cutting saw blade.

[0102] The control method of the cutting device in this embodiment enables the cutting of a steel wire rope core conveyor belt using the cutting device described above. During the cutting process, the base frame 1 facilitates the arrangement of the clamping part 2, the moving part 3, and the cutting part 4. The clamping part 2 facilitates the placement of the cutting device on the conveyor belt. Through the coordinated operation of the clamping part 2 and the moving part 3, the cutting end of the cutting part 4 can easily cut the conveyor belt along the cutting groove 5. Furthermore, by placing the cutting part 4 on the moving part 3, the cutting part 4 can change its cutting position as the moving part 3 moves, thereby improving the cutting efficiency of the cutting device in cutting the conveyor belt.

The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations.
