Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal, and specifically relates to a dust removal device for cutting special plastic pipes. Background Art

[0002] Special plastic pipes generally refer to pipes made of special materials or applied in special environments, and usually have excellent physical properties such as high temperature resistance, corrosion resistance, and high pressure resistance. And the flow rate of the conveyed medium is relatively large, and the pipe diameter is usually relatively large.

[0003] General shearing and cutting devices are not applicable to cutting such pipes. The rotary cutting method is mostly used, and the saw blade rotates circumferentially along the pipe. Since it is necessary to center and fix both sides of the pipe, relatively large openings are reserved at the inlet and outlet of the cutting body for pipes of different specifications to pass through. Therefore, dust is easily dispersed outward and debris splashes during the cutting process, causing environmental pollution in the atmosphere or indoors. And during the circumferential cutting process, the spraying directions of the dust and debris change in real time, and the use of exhaust pipes and cyclone dust collectors for directional dust collection has relatively low dust removal efficiency.

[0004] At the same time, during the circumferential cutting process, the cutter presses on the middle of the pipe, and pipes with relatively small diameters are prone to deformation or deviate from the center when the cut is large.

[0005] Therefore, the present application proposes a dust removal device for cutting special plastic pipes to overcome the above defects. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a dust removal device for cutting special plastic pipes.

[0007] To achieve the above object, the present invention provides the following technical solution: A dust removal device for cutting special plastic pipes, including an equipment body. The equipment body further includes a clamping mechanism arranged at the inlet and outlet. The dust removal device for cutting also includes a circular frame, which is fixedly installed inside the equipment body through a mounting frame; a dust suction box, which is arranged on the circular frame to support the plastic pipe, and a dust suction opening is opened on the dust suction box; a dust collector, which is arranged on the circular frame and communicated with the dust suction box to suck the cutting dust and debris around the circular frame; a positioning component, which is movably arranged on the circular frame to lock the position of the dust suction box; a cutting module, which is movably arranged on the circular frame to cut the pipe; wherein, two dust suction boxes are symmetrically arranged, and the two dust suction boxes and the cutting module achieve three-point centering of the pipe.

[0008] Preferably, the circular frame includes a rotating mechanism and a driving frame. The rotating mechanism includes a toothed ring installed on the inner ring of the circular frame and a planetary gear installed on the driving frame, so that the driving frame can rotate around the circular frame through the planetary gear;

[0009] The circular frame further includes a first driving machine disposed on the driving frame for driving its rotation;

[0010] The dust suction box, the dust collector, the positioning assembly and the cutting module are installed on the driving frame.

[0011] Preferably, the cutting module includes a cutter, and the cutting device of the cutting module is slidably installed on the cutter. It further includes a second driving machine and a threaded block installed on the back of the driving frame. The threaded block is connected to the slider on which the cutting device is installed to drive it to move along the cutter.

[0012] Preferably, the dust suction box includes a first dust suction port and a second dust suction port. The first dust suction port is located on both sides of the cutting device of the cutting module, and the first dust suction port extends upward beyond the upper part of the pipe;

[0013] One end of the dust suction box is bent at an angle of -°, and a second dust suction port is opened inside the bent angle of the dust suction box. The vertical projection of the second dust suction port is aligned and collinear with the vertical projection of the saw blade of the cutting device.

[0014] Preferably, isolation cotton is provided on both the inner and outer sides of the angle of the dust suction box. The isolation cotton cooperates with the angle of the dust suction box and the peripheral surface of the pipe to form a relatively enclosed cavity.

[0015] Preferably, the dust collector is installed on the driving frame in a fan-shaped structure. The dust collector includes a filtering component inserted into one end of the integrated cover of the filtering component, a Y-shaped pipe connected to the two dust suction boxes, and a fan installed on the dust collector;

[0016] The air inlet of the fan is communicated with one end of the integrated cover of the dust collector.

[0017] Preferably, the positioning assembly includes an elastic rod, and the top end of the elastic rod is elastically connected with a fixing member. The fixing member is fixedly connected to one end of the dust suction box. The dust suction box can be clamped on the outer side of the pipe by being pushed by the elastic rod;

[0018] A linear through slot is opened on the driving frame, and a positioning hole is opened on the fixing member. A fastening bolt is inserted therein to cooperate with the linear through slot to fix the position of the fixing member.

[0019] Preferably, the elastic extension direction of the elastic rod is consistent with the radial direction of the pipe.

[0020] Preferably, an arc-shaped through slot is opened on the outer side of the dust collection cover of the dust collector as a discharge port, and an arc-shaped plate is provided at the discharge port for covering.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] After the length of the positioning component is adjusted and locked, the position of the dust suction box is locked accordingly. Therefore, there are a total of three centering settings for the pipe, namely two clamping mechanisms and one dust suction box. When the cutting device performs cutting, the two dust suction boxes that always form symmetrical supports maintain the posture of the pipe so that it cannot shift. And the dust suction box is connected to the dust collector. The dust suction openings provided on the dust suction box can absorb the dispersed particles or debris at the splashing area and finally be sucked into the dust collector for collection and separation. The dust suction box is used to collect dust at the source, so the outward dispersion of dust is greatly reduced, improving the dust removal efficiency.

[0023] The dust suction port 1 and the dust suction port 2 are used to suck air at different positions. When the saw blade of the cutting device is cutting, the dust, debris and other dispersed particles splashing outward are collected by the dust suction port 1 on both sides. Since the dust suction ports 1 on both sides extend upward beyond the circumferential side of the pipe, the dispersed particles can be collected into the interior before they diffuse and then be sucked away along with the air flow. The dust suction port 2 is used for directional suction of the cut seam, and during the rotation of the dust suction box, it will coincide with the cut mark. The debris and dust ejected into the interior of the pipe are sucked out to ensure that the dust inside the separated pipe has also been processed. Brief Description of the Drawings

Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 8 shown, the present invention provides a dust removal device for cutting special plastic pipes, including an equipment body 100. The equipment body 100 further includes a clamping mechanism 101 arranged at the inlet and outlet. The dust removal device for cutting also includes a circular frame 200, which is fixedly installed inside the equipment body 100 through a mounting bracket 102;

[0035] A dust suction box 300, which is arranged on the circular frame 200 to support the plastic pipe, and a dust suction through port is opened on the dust suction box 300;

[0036] A dust collector 400, which is arranged on the circular frame 200 and communicated with the dust suction box 300 to suck the cutting dust chips around the circular frame 200;

[0037] A positioning assembly 500, which is movably arranged on the circular frame 200 to lock the position of the dust suction box 300;

[0038] A cutting module 600, which is movably arranged on the circular frame 200 to cut the pipe;

[0039] Among them, two dust suction boxes 300 are symmetrically arranged, and the two dust suction boxes 300 and the cutting module 600 achieve three-point centering for the pipe.

[0040] The pipe passes through the inlet and outlet of the equipment body 100, and is positioned and centered at the start of cutting. The cylinder on the external clamping mechanism 101 is started, and the clamp is made to close towards the middle to lift the pipe and center it. Before the clamping mechanism 101 is started, a person enters the interior through the door opening, adjusts the extension length of the positioning assembly 500 and locks it after adjustment, thereby locking the centering position of the dust suction box 300.

[0041] Therefore, the pipe is centered at three places, namely two clamping mechanisms 101 and one dust suction box 300. When the cutting device cuts, the two dust suction boxes 300 that always form symmetric supports maintain the posture of the pipe so that it cannot shift.

[0042] Moreover, the dust suction box 300 is connected to the dust collector 400. The dust suction openings provided on the dust suction box 300 can absorb the dispersed particles or debris at the splashing place and finally be sucked into the dust collector 400 for collection and separation. The dust suction box 300 is used to collect dust at the source, so it greatly reduces the outward dispersion of dust and improves the collection efficiency.

[0043] As for the power supply of the equipment thereon, it is completed through a power supply slip ring.

[0044] Such as Figure 2 、 Figure 3 and Figure 6 As shown, the circular frame 200 includes a rotating mechanism 201 and a driving frame 203. The rotating mechanism 201 includes a toothed ring installed on the inner ring of the circular frame 200 and a planetary gear installed on the driving frame 203, so that the driving frame 203 can rotate around the circular frame 200 through the planetary gear;

[0045] The circular frame 200 further includes a driving machine one 202 provided on the driving frame 203 for driving its rotation;

[0046] The dust suction box 300, the dust collector 400, the positioning component 500 and the cutting module 600 are installed on the driving frame 203.

[0047] Such as Figure 6 and Figure 7 As shown, the cutting module 600 includes a cutter 601. The cutting device of the cutting module 600 is slidably installed on the cutter 601. It also includes a driving machine two 602 and a threaded block 603 installed on the back of the driving frame 203. The threaded block 603 is connected to the slider installed with the cutting device to drive it to move along the cutter 601.

[0048] The cutting module 600 is used to drive the cutting device to move on the surface of the pipe and cut it. The driving machine two 602 drives the threaded block 603 to drive the driving machine two 602 to move vertically. Thus, the distance between the cutting device and the pipe is controlled, and finally it can be pressed on the pipe for cutting.

[0049] Such as Figure 7 As shown, the dust suction box 300 includes a dust suction opening one 302 and a dust suction opening two 303. The dust suction opening one 302 is located on both sides of the cutting device of the cutting module 600, and the dust suction opening one 302 extends upward beyond the pipe;

[0050] One end of the dust box 300 is bent at an angle of 120-135 degrees, and a second dust inlet 303 is provided inside the bent angle of the dust box 300. The vertical projection of the second dust inlet 303 is aligned with the vertical projection of the saw blade of the cutting device.

[0051] The suction port 1 302 and the suction port 2 303 are used to suck air at different positions. When the saw blade of the cutting device is cutting, dust and other dispersed particles that are splashed to the outside are collected by the suction port 1 302 on both sides. Since the suction ports 1 302 on both sides extend upward and cover the sides of the pipe, the dispersed particles can be collected inside before they diffuse and then be sucked away with the airflow.

[0052] The second suction port 303 disposed under the pipe performs directional suction on the cut seam. Since the vertical projection of the second suction port 303 and the vertical projection of the saw blade of the cutting device are aligned and collinear, the dust box 300 will overlap with the cut seam during the rotation process. The debris and dust ejected into the pipe are sucked out to ensure the cleanliness of the pipe when it is separated.

[0053] The bending angle of 120-135° is generally universal and can adapt to special pipes with a diameter of more than 150mm. The angle can also be reasonably adjusted according to actual usage to maximize efficiency.

[0054] like Figure 3 and Figure 4 As shown, isolation cotton 301 is provided on both inner and outer sides of the included angle of the dust collection box 300, and the isolation cotton 301 cooperates with the included angle of the dust collection box 300 and the peripheral surface of the pipe to form a relatively closed cavity.

[0055] The cavity covers the cutting gap inside, so the suction port 2 303 can focus on the cutting gap when suction is performed. The isolation cotton 301 is used here because it has certain shielding and isolation properties and elastic and soft texture. It can deform quickly when it contacts the pipe surface and will not form a strong supporting effect on it.

[0056] In addition, when it contacts the surface of the pipe, it moves relatively smoothly without any obstruction. It is not recommended to use rubber products for plugging here. Compared with straight lines, rubber products are relatively difficult to deform and have strong elasticity, which is not suitable for centering. Moreover, when it contacts the surface of the pipe, it will produce a relatively large damping effect, resulting in problems such as uneven movement and even centering failure.

[0057] like Figure 3As shown, the dust collector 400 is installed on the driving frame 203 in a fan-shaped structure. The dust collector 400 includes a filter component 401 inserted at one end of the integrated cover of the filter component, a Y-shaped pipe 402 connected to the two dust suction boxes 300, and a fan 403 installed on the dust collector 400;

[0058] The air inlet of the fan 403 is connected to one end of the integrated cover of the dust collector 400.

[0059] The dust collector 400 is set in a fan-shaped structure to maximize the volume that can be set on the circular frame 200. Its dust collection cover is connected to the dust suction boxes 300 on both sides through the Y-shaped pipe 402, and the debris and dust therein are concentrated into the dust collector 400. A one-way valve flap can be set in the Y-shaped pipe 402, and the conduction direction points to the dust collection cover. It is used to block the backflow and leakage of the dispersed particles in the dust collection cover, and at the same time reduce the impact on the suction.

[0060] The filter component 401 has a filter plate inserted at one end of the dust collection cover, and the connecting pipeline of the Y-shaped pipe 402 is arranged in the cavity at the end where the filter plate is inserted. Therefore, air circulation can be realized and dispersed particles such as debris or dust can be blocked inside.

[0061] As for the installation position and form of the filter component 401, it can be reasonably adjusted according to the size of its flow rate. For example, when a relatively large air flow rate is required to achieve better dust removal efficiency, the filtering area of the filter component 401 can be enlarged, and it is installed at both ends of the dust collection cover, and the cavities at both ends are connected and set. It is used to conduct to an exhaust pipeline.

[0062] Such as Figure 3 and Figure 4 As shown, the positioning component 500 includes an elastic rod 501. The top end of the elastic rod 501 is elastically connected with a fixing piece 502. The fixing piece 502 is fixedly connected to one end of the dust suction box 300. The dust suction box 300 can be pushed by the elastic rod 501 to clamp on the outside of the pipe;

[0063] A through slot 503 is opened on the driving frame 203, and a positioning hole is opened on the fixing piece 502, in which a fastening bolt 504 is inserted to cooperate with the through slot 503 to fix the position of the fixing piece 502.

[0064] The elastic rod 501 can push the dust suction box 300 to close to the middle of the circular frame 200. During the initial pipe alignment process, the elastic rod 501 is pushed to push the dust suction box 300 to push one end of the pipe towards the middle of the circular frame 200. After determining the position, the telescopic length of the elastic rod 501 is adjusted, and it is fixed and installed after tightening with the fastening bolt 504.

[0065] By Figure 7As shown, the second dust suction port 303 is opened in the middle of the fold of the dust suction box 300, and the position where the saw blade cuts is also here. Therefore, after the pipe is cut, the newly formed end still overlaps on the dust suction box 300. Only after the first adjustment is made can this standard position be maintained until the pipe cutting is completed. Subsequent pipes of the same specification can also be cut and processed using this standard position.

[0066] A positioning component 500 is used to control the opening and closing of the two dust suction boxes 300, mainly for adapting and adjusting pipes with different inner diameters.

[0067] As Figure 2 and Figure 3 shown, the elastic extension direction of the elastic rod 501 is consistent with the radial direction of the pipe.

[0068] Specifically, the extension direction of the elastic rod 501 coincides with the radial direction of the circular frame 200, so it can support the pipe and finally make it coaxial with the circular frame 200. The orientation of the positioning component 500 can be restricted by the cooperation of the slotted through-hole 503 and the fastening bolt 504. The extension direction of the slotted through-hole 503 is parallel to the radial direction of the circular frame 200. Therefore, the fastening bolt 504 inserted therein can play a limiting role.

[0069] Or it can also be achieved by arranging a guiding slide rail on the driving frame 203, making the fixing part 502 slide and engage in the guiding slide rail to limit the jacking direction of the positioning component 500. These two methods can be used interchangeably.

[0070] As Figure 7 shown, an arc-shaped through-hole is opened on the outer side of the dust collection cover of the dust collector 400 as a discharge port, and an arc-shaped plate is arranged at the discharge port for covering.

[0071] The overall shape of the dust collection cover of the dust collector 400 is fan-shaped, and the arc-shaped through-hole is opened on the outer peripheral side. Therefore, when the dust collector 400 rotates to the lower part, the dust and debris inside the integrated cover will be concentrated at the through-hole. Only by unlocking the arc-shaped plate in front of the through-hole can the dust and debris inside be directly discharged.

[0072] The working principle and usage process of the present invention:

[0073] Manually enter the interior through the door opening. After adjusting and locking the extension length of the positioning component 500, the centering position of the dust suction box 300 is locked.

[0074] Therefore, a total of three centering settings are made for the pipe, namely two clamping mechanisms 101 and one dust suction box 300. When the cutting device cuts, the two dust suction boxes 300 that always form symmetric support maintain the posture of the pipe so that it cannot shift.

[0075] Moreover, the dust suction box 300 is communicated with the dust collector 400. The dust suction openings formed on the dust suction box 300 can absorb the dispersed particles or debris at the splashing position and are finally sucked into the dust collector 400 for collection and separation. The dust suction box 300 is used to collect dust at the source.

[0076] The dust suction box 300 is provided with a first dust suction port 302 and a second dust suction port 303 for sucking air at different positions. When the saw blade of the cutting device is cutting, the dust, debris and other dispersed particles splashing outward are received by the first dust suction ports 302 on both sides. Since the first dust suction ports 302 on both sides extend upward and cover the circumferential side of the pipe, the dispersed particles can be received inside before they diffuse and then are sucked away along with the air flow.

[0077] The one 303 arranged below the pipe is for directional suction of the cutting seam, so it will coincide with the cutting mark when the 300 rotates. The debris and dust sprayed into the pipe are sucked out.

[0078] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0079] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
