Description

Technical Field

[0001] The invention belongs to the field of cutting machine tools, and in particular relates to a belt-pulling high-precision dust-free cutting machine. Background Art

[0002] The belt conveyor in the belt-pulling cutting machine is an important component, which transports materials through the continuous movement of the belt. For example, on a pipe production line, the belt traction machine will continuously and automatically lead the pipe that has been extruded and cooled and shaped by the extruder out from the head of the machine, and then the cutting machine will cut it according to the set length; for example, on a plate production line, the belt traction machine will pull the entire plate to the cutting machine, and the cutting machine will complete the slitting of the entire plate. The application of the belt traction method in the cutting machine has many advantages, such as being able to adapt to a variety of materials, including plates and coils of various shapes, sizes and materials, and being able to ensure the stability and cutting accuracy of the cutting process; for equipment with a negative pressure dust suction device installed on the cutting head, the cutting machine also has the advantage of dust-free cutting.

[0003] Although the existing belt traction type cutting machine can be used for different types of materials, most of the independent belt traction devices can only traction one type of material after installation, otherwise it will affect the stability of transmission. For example, a cutting machine traction device disclosed in CN212886271U is only suitable for pipe fittings. Another example is the belt traction precision cutting machine disclosed in CN210819779U is also only suitable for pipe fittings, and an automatic plate cutting device disclosed in CN111452105A is only suitable for plates. This will lead to a decrease in equipment utilization. For workshops with small production scales and many product types, it will also increase the number of vehicles. The comprehensive investment cost in time; secondly, there are still some problems with the belt traction device during the traction process. For example, most belt traction machines adopt a horizontal transmission method. For example, the belt traction precision cutting machine disclosed in CN210819779U will slip for a distance for the material just fed. Although it will enter a stable transmission state as the feeding length increases, it will directly affect the actual service life of the belt. If it works in this state for a long time, it will also affect the tightness of the belt. In addition, most of them use a non-toothed transmission belt, which will affect the transmission accuracy of the material to the cutting head. Summary of the Invention

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Examples, such as Figures 1-10As shown, the present invention provides a belt-traction type high-precision dust-free cutting machine, comprising a chassis 1, wherein a partition 2 is provided inside the chassis 1 and near the middle thereof, a cutting chamber 11 is provided on one side of the partition 2, a discharge port 13 is provided on one side of the cutting chamber 11, a traction chamber 12 is provided on the other side of the partition 2, a feed port 14 is provided in the traction chamber 12 at a position opposite to the discharge port 13, and a belt traction device 3 is provided in the traction chamber 12. A cross slide 6 is provided in the cutting chamber 11, and the cross slide 6 is composed of a vertical lead screw slider mechanism and a horizontal lead screw slider mechanism. The cross slide 6 has vertical and horizontal movement functions and a connecting seat is provided at its moving end, on which a cutting working head 7 is detachably mounted, and a dust suction pipe 71 is provided on the cutting working head 7, and the negative pressure end of the dust suction pipe 71 is connected to a negative pressure device 8 provided on the outside of the chassis 1 through a pipeline. The front and back of the chassis 1 are equipped with transparent windows for observing the working conditions of the equipment in the cutting chamber 11 and the pulling chamber 12. The negative pressure device 8 is equipped with a filter screen or filter bag. Its negative pressure capacity can recover and filter dust, debris, and smoke generated during the cutting process to ensure that the equipment operates in a dust-free state. The cutting head 7 can use different cutting heads according to the cutting requirements. For example, a saw blade is generally used for cutting pipes. The slide on the cross slide 6 mechanism can be detachably assembled with the cutting head 7 to improve the utilization rate of the equipment.

[0033] In order to improve the material conveying accuracy of the present equipment, the belt traction device 3 provided by the present equipment includes an upper belt conveyor 31 and a lower belt conveyor 32. A conveying gap 33 for conveying materials is formed between the upper belt conveyor 31 and the lower belt conveyor 32. The conveying gap 33 is inclined at 1°-3° toward the feed inlet 14. The lower belt conveyor 32 includes two transmission gear rollers 321 at its two ends, namely a front transmission gear roller and a rear transmission gear roller. One of the front transmission gear roller and the rear transmission gear roller serves as an active gear roller and can receive power input from a second reduction motor 325. A height adjustment gear roller 322 and a tensioning gear roller 323 are respectively provided above and below the center lines of the two transmission gear rollers 321. The transmission gear rollers 321, the height adjustment gear roller 322, and the tensioning gear roller 323 are meshed and driven by a synchronous belt 324. The front transmission gear roller and the rear transmission gear roller can be at the same level, and the height adjustment gear roller 322 can tilt the top level of the synchronous belt 324 to a slope, which is the inclination angle of the conveying gap 33. Specifically, the upper belt conveyor 31 and the lower belt conveyor 32 are used to clamp the material on the one hand, and to convey the material box cutting chamber 11 by friction transmission on the other hand. At the same time, since the transmission gap 33 of the belt traction device 3 is inclined at a small angle, part of the inertia and gravity of the material can be utilized during the transmission process, which can reduce the probability of long-distance slippage, which is conducive to ensuring that the upper belt 314 and the synchronous belt 324 have a longer actual service life; furthermore, for the main working parts of gravity bearing and friction transmission, that is, the synchronous belt 324, through the meshing transmission method, it cooperates with the transmission gear roller 321, the height adjustment gear roller 322 and the tensioning gear roller 323. Compared with the pure friction transmission, the transmission accuracy of the lower belt conveyor 32 is greatly improved, avoiding slippage on the transmission path, which is conducive to improving the accuracy of material transmission, and thus ensuring the cutting quality in the cutting chamber 11.

[0034] In conjunction with the belt traction device 3, the present invention provides a multifunctional conveying device 4 connected to the outside of the feed port 14. The conveying direction of the multifunctional conveying device 4 is the same as the inclination direction of the conveying gap 33. One end of the multifunctional conveying device 4 is hinged to the chassis 1, and the other end of the multifunctional conveying device 4 is provided with a lifting support device 5. The multifunctional conveying device has a plate conveying mode and a pipe conveying mode. The multifunctional conveying device includes at least three roller assembly components 41 distributed side by side. The roller assembly components 41 can switch between the plate conveying mode and the pipe conveying mode by adjusting the rotation angle. Among them, the lifting support device 5 can rotate all the roller assembly components 41 around the hinge center of the multifunctional conveying device 4 and the chassis 1 through telescopic drive to achieve the purpose of fine-tuning the inclination angle for better connection with the conveying gap 33. At the same time, the multifunctional conveying device 4 can serve the feeding and conveying operations of different materials in the workshop through mode switching, and the comprehensive utilization rate is high.

[0035] Furthermore, if Figure 1 and Figure 6 As shown, the multifunctional conveying device 4 provided by the present invention includes two relatively distributed end plates 42, wherein a fixed hinge 43 is provided on one of the end plates 42, and a movable hinge 44 hinged to the lifting support device 5 is provided at the bottom of the other end plate 42. The roller group component 41 is installed between the end plates 42 and is provided with an adjustment port 421 that cooperates with the end of the roller group component 41. The multiple adjustment ports 421 include at least two side ports distributed in an inverted V shape and an intermediate port distributed between the side ports. A dividing plate 45 is provided in the adjustment port 421, and the dividing plate 45 is axially connected to the end of the roller group component 41. A dividing hole is provided on the dividing plate 45. A plurality of positioning holes 422 corresponding to the dividing holes are provided in the adjustment port 421, and the dividing hole and the positioning hole 422 are connected by a positioning pin 46. When the support roller surface of roller assembly 41 is horizontal, it can be used to roll and support sheet materials. When the support roller surface and the support roller surfaces of other roller assembly 41 are in a V-shaped state, they can roll and support pipe materials. The movable hinge 44 can adaptively rotate with the end of the lifting support device 5 under the telescopic drive of the lifting support device 5, and the multifunctional conveyor device 4 as a whole rotates around the hinge center of the fixed hinge 43 to adjust the actual support and clamping angle of the roller assembly 41. The indexing plate 45 preferably adopts a hollow T-shaped structure. The center of the indexing plate 45 is keyed to the end of the roller assembly 41. Therefore, the rotation of the indexing plate 45 reflects the rotation angle of the roller assembly 41. Inserting the positioning pin 46 into the corresponding positioning hole 422 and the indexing hole completes the adjustment of the angle of the roller assembly 41.

[0036] In order to improve the utilization rate of the roller assembly 41, as Figure 6-Figure 9 As shown, the roller assembly component 41 provided by the present invention includes two hexagonal end heads 411, and eight mounting plates 412 are arranged between the two end heads 411. The eight mounting plates 412 are distributed in four pairs and are respectively arranged on the top edge, bottom edge and two side edges of the end heads 411. A plurality of rolling rollers 413 are arranged between each pair of mounting plates 412 and are spaced apart along the length direction thereof. A support shaft 414 is provided at the center of the end head 411, and the shaft end of the support shaft 414 passes through the adjustment hole and cooperates with the dividing plate 45. Among them, the end 411 and the mounting plate 412 can be connected by welding, and the support shaft 414 is pre-assembled between the two end heads 411; the mounting plate 412 provides an installation node for the rolling roller 413, and different rows of rolling rollers 413 are used for the roller group component 41 to support the plate and pipe in different modes. For example, the rolling rollers 413 on the top and bottom edges are used to support the plate, and the rolling rollers 413 on the side form a V-shaped clamping relationship with the rolling rollers 413 on the adjacent roller group component 41 to support the pipe.

[0037] In order to improve the structural strength of the roller assembly 41, the present invention provides a plurality of reinforcing plates 415 that are spaced apart and connected to the mounting plate 412 between the end heads 411. The reinforcing plates 415 are hexagonal in structure and a through hole is provided at the center thereof, through which the support shaft 414 passes. The reinforcing plates 415 can effectively prevent the mounting plate 412 from bending and deforming, thereby improving the installation reliability of the rolling roller 413 on the mounting plate 412 and reducing the probability of roller missing.

[0038] Furthermore, the present invention adopts a design in which three roller group components 41 are formed into a group. Taking into account the space utilization, the top side length of the end head 411 provided by the present invention is greater than the bottom side length, and the lengths of the two side sides adjacent to the top side of the end head 411 are less than the lengths of the two side sides connected to the bottom side. In this way, the bottom of the middle roller assembly 41 faces upward, while the tops of the other two roller assemblies 41 face upward. This ensures that the multiple roller assemblies 41 provide effective support slopes for rolling and supporting sheet materials while maintaining a high degree of space conservation. To support pipes, the roller assembly 41 with the top facing upward is flipped to one side and the rolling rollers 413 on its side are turned upward. At the same time, the relative position of the roller assembly 41 in the side opening is adjusted higher. The roller assembly 41 with the bottom facing upward is then moved upward along the middle opening until the three roller assemblies 41 form at least two V-shaped rolling support channels. Because the roller assemblies 41 are all adaptively moved upward, and the bottom surface of the pipe in the rolling support channel is not lower than the top surface of the end plate 42, the pipe can be effectively conveyed forward. To ensure the safe conveyance of pipes, a U-shaped opening can be opened on the end plate 42 at a position corresponding to the rolling support channel to provide a sufficient conveying path for the continuous conveyance of smaller pipes.

[0039] In order to improve the accuracy of the plate conveying on the multifunctional conveying device 4 and the belt traction device 3, the present invention is provided with a limiting roller 47 on the side of the end 411 for limiting the edge of the plate. The limiting roller 47 can be used to prevent the plate from running off the track, and in order to match the plates of different widths, a plurality of connecting holes can be opened on the end 411 for installing the limiting roller 47, thereby obtaining a better limiting effect.

[0040] like Figure 3As shown, taking into account the different sizes of the conveying gap 33 required for conveying plates and conveying pipes, in order to meet the conveying performance of materials in different modes, the upper belt conveyor 31 provided by the present invention includes two driven rollers, namely a front driven roller 311 and a rear driven roller 312, and an active roller 313 is arranged between the front driven roller 311 and the rear driven roller 312. The active roller 313 and the driven roller are driven by the upper belt 314. A first reduction motor 315 is provided at one end of the active roller 313, and a lifting adjustment device 34 for adjusting the conveying gap 33 is provided at both ends of the active roller 313. An angle adjustment cylinder 35 is provided at both ends of the rear driven roller 312, and the top of the angle adjustment cylinder 35 is hinged to the chassis 1. Among them, the first reduction motor 315 is used to drive the active roller 313, and the active roller 313 inputs power to the front driven roller 311 and the rear driven roller 312 through the upper belt 314, so that the upper belt 314 has a transmission surface with appropriate tightness; the lifting and adjusting device 34 can adjust the actual height of the transmission surface of the upper belt conveyor 31, and the angle adjustment cylinder 35 can be extended and retracted to adapt to the length, so that the gap height of the transmission gap 33 is controllable. For conveying plates, the gap height can be adjusted to be smaller, and for conveying pipes, the gap height can be adjusted to be higher, so that the upper and lower surfaces of the transmission gap 33 can obtain effective contact pairs with the plates and pipes, and thus can perform reasonable and stable transmission, ensuring the actual utilization rate of this device in different modes.

[0041] Furthermore, the roller diameter of the active roller 313 provided by the present invention is larger than the roller diameter of the driven roller, the active roller 313 is distributed close to the front driven roller 311, and the height adjustment gear roller 322 is distributed close to the rear transmission gear roller. The part of the upper belt 314 that is transmitted and matched between the active roller 313 and the front driven roller 311 is the braking surface, the part of the upper belt 314 that is transmitted and matched between the active roller 313 and the rear driven roller 312 is the upper surface of the transmission gap 33, and the part of the synchronous belt 324 that is transmitted and matched with the height adjustment gear roller 322 and the front transmission gear roller bracket is the lower surface of the transmission gap 33. In this way, before the profile approaches the cutting chamber 11, the braking surface and the synchronous belt 324 can form a closed surface through the angle adjustment cylinder 35, and the traction output end of the belt traction device 3 is closed first to control the actual output of the profile, which is beneficial to improve the actual transmission accuracy of the material, thereby meeting the cutting size requirements of the product; for the transmission gap 33, there is a long parallel corresponding surface between the upper belt 314 and the synchronous belt 324, thereby ensuring sufficient contact with the material, which is beneficial to improving the transmission efficiency.

[0042] In order to improve the practicality of the lifting and adjusting device 34, the lifting and adjusting device 34 provided by the present invention includes a cantilever beam 341, the bottom end of the cantilever beam 341 is provided with a light hole that rotates with the roller end of the active roller 313, the side of the cantilever beam 341 is provided with a connecting plate 342, the partition 2 is provided with a skateboard rail mechanism 343 connected to the connecting plate 342 by bolts, the top of the skateboard rail mechanism 343 is provided with a fixed seat 344, the middle of the fixed seat 344 is provided with a screw rod 345 connected to the top of the cantilever beam 341, and the top of the screw rod 345 is provided with a handwheel 346 that rotates with it. Among them, the hole wall of the light hole is polished with high precision, and can play the role of a bearing when matched with the roller end of the active roller 313, so that the active roller 313 has a stable rolling center; by manually rotating the handwheel 346, the actual height of the handwheel 346 on the screw rod 345 can be changed, and the cantilever beam 341 can be able to make stable linear motion along the slide rail mechanism 343 to complete the adjustment operation of the transmission gap 33, and ensure that the transmission gap 33 has good stability after the adjustment is set, so as to ensure that the material has good transmission controllability in the transmission gap 33.
