Description

Technical Field

[0001] This invention relates to the field of flooring production and cutting technology, specifically to a dust-free cutting device and its implementation method for PVC wood-plastic flooring production. Background Technology

[0002] Wood-plastic composite flooring is a new type of environmentally friendly wood-plastic composite material product. The lignin produced during the production of medium and high density fiberboard is added to recycled plastic and granulated to form wood-plastic composite material, which is then extruded to make wood-plastic flooring. This type of flooring can be used in garden landscapes, villas and other outdoor platforms. Traditional wood-plastic flooring produces a lot of dust when cutting. This dust not only requires workers to clean up while cutting, but also reduces working time and effort.

[0003] Chinese Patent Publication No. CN219294129U discloses a dust-free cutting device for wood-plastic composite flooring substrates. This dust-free cutting device for wood-plastic composite flooring substrates uses a combination of a cylinder, a telescopic rod, a cutting machine, a fan, and a dustproof box. The dustproof box can surround the waste chips generated during the cutting of wood-plastic composite flooring, preventing them from flying. In addition, the fan can blow away the nearby dust chips during the cutting process, allowing the workers to clearly see the cutting process, ensuring the accuracy of the operation, and also ensuring the safety of the workers. This expands the scope of application of the device and is conducive to its promotion and use.

[0004] In the aforementioned patent, the cutting debris is surrounded and isolated by the box space. However, the debris inside the box is still blown around by the fan, causing a large amount of debris to enter the gaps of the equipment, thus affecting the normal operation of the equipment. Furthermore, the waste inside the box cannot be cleaned in a timely manner. Therefore, it does not meet the existing needs. In response, a dust-free cutting device for PVC wood-plastic flooring production and its implementation method are proposed. Summary of the Invention

[0008] Preferably, the dust collection grid frame has dust collection ducts on both sides of the top and dust discharge ducts on both sides of the bottom. The dust collection grid frame is equipped with multiple unit fans inside, and the unit fans are connected to the fan cabinet through pipes.

[0009] Preferably, damping gates are provided on both sides above the unit fan. One end of the damping gate is rotatably connected to the dust collection grid frame through a damping coupling. A partition wind plate is provided above the damping gate, extending to the inner side of the dust collection duct. A side slope groove is provided below the damping gate, extending through to the upper side of the dust collection tray.

[0010] Preferably, the bottom of the gantry cutting frame is equipped with a lamp, and both sides of the gantry cutting frame are equipped with slides. A horizontal moving rail is provided on one side of the lamp, and the horizontal moving rail is connected to the gantry cutting frame by screws. A support shaft is provided below the horizontal moving rail, and the support shaft is slidably connected to the horizontal moving rail. A laser cutting component is provided at the bottom of the support shaft.

[0011] Preferably, the outer surface of the cutting table is provided with a toothed plate, which is connected to the cutting table by screws. Wheel boxes are provided on both sides of the cutting table, and track wheels are provided inside the wheel boxes. A sensing module is provided on one side of the track wheel, and the sensing module is connected to the wheel box by a bracket.

[0012] Preferably, both ends of the gantry cutting frame are provided with lifting brackets, which are connected to the cutting preparation table by screws. A cylinder is provided on one side of the lifting bracket, and a biting shaft is provided above the cylinder. The biting shaft is connected to the cutting table by screws. A push rod is provided on the top of the cylinder. Correction sleeves are provided on both sides of one end of the gantry cutting frame.

[0013] Preferably, the cutting preparation table is provided with a rail inside, the wheel box is slidably connected to the rail via a track wheel, a straightening frame is provided at one end of the rail, the straightening frame is connected to the cutting preparation table by screws, and a control box is provided on one side of the cutting preparation table.

[0014] Preferably, an electrical box is provided at the bottom of the cutting preparation table, and a motor module is provided at one end of the electrical box. The motor module is meshed and rotatably connected with a transmission gear, and the sleeve is slidably connected to the cutting preparation table through the transmission gear.

[0015] A method for implementing a dust-free cutting device for PVC wood-plastic flooring production includes the following steps:

[0016] Step 1: Place the base plate flat on top of the cutting table. At this time, the lifting brackets at both ends will lower the cutting table so that the cutting table contacts the rail. The rail will then move the cutting table towards the cutting processing table. After the cutting table moves to the cutting processing table, the suspension rail will contact the wheel box for transmission.

[0017] Step 2: After the cutting table is completely moved and covers the cutting processing table, turn on the power of the cutting processing table and cut the bottom plate above the cutting table through the gantry cutting frame and laser cutting components. During the cutting process, the fan inside the dust collection grid starts running and sucks the debris and dust generated during cutting into the dust collection grid through the dust collection air channel.

[0018] Step 3: The debris and dust sucked into the dust collection grid will come into contact with the partition air plate. Most of the debris will slide down the partition air plate to the damping gate area after hitting the partition air plate. A small part of the debris and dust will enter the area where the unit fan is located. The debris that slides down to the damping gate area can be discharged into the dust collection tray through the dust discharge window groove, while the debris and dust that enter the unit fan area will enter the side slope groove along the airflow formed by the damping gate and the fan.

[0019] Step 4: When too much debris is sucked in, the weight on the damping gate increases, and the gate rotates downward to open. At this time, the debris can be discharged directly through the side ramp. After the cutting is completed, the dust collection tray can be pulled out for cleaning.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the fan inside the dust collection grid frame starts running during the cutting process, and the dust and smoke generated during cutting are sucked into the dust collection grid frame through the dust collection air channel. This can prevent the dust generated during cutting from spreading in the processing area, realize dust-free processing operation, and the laser cutting component itself does not generate a large amount of cutting debris during the cutting process compared with the traditional blade cutting method, and the debris is not affected by the centrifugal force of the blade, effectively reducing dust.

[0022] 2. In this invention, the debris and dust sucked into the dust collection grid will come into contact with the partition air plate. After most of the debris hits the partition air plate, the suction force of the fan will decrease on this part of the debris. At this time, the debris on the partition air plate will slide to the damping gate area and then be discharged into the dust collection tray through the dust discharge window groove on one side. A small part of the debris and dust will enter the area where the unit fan is located. When the damping gate is in the closed state, an inclined cavity structure will be formed between the damping gate and the unit fan. At this time, the airflow generated by the fan will enter the side slope groove area along the surface of the damping gate and be discharged through the side slope groove. In this way, the debris and dust entering the unit fan area will enter the side slope groove along the airflow formed by the damping gate and the fan. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the issue of debris still being blown around inside the enclosure by the fan, causing a large amount of debris to enter the equipment's gaps and thus affecting its normal operation, please refer to [link to relevant documentation]. Figure 1-2 This embodiment provides the following technical solution:

[0032] A dust-free cutting device for PVC wood-plastic flooring production includes a cutting table 1 and a cutting preparation table 2, and a cutting plate 3 disposed above the cutting preparation table 2. A track drive assembly 101 is disposed on one side of the cutting table 1, and a gantry cutting frame 4 is disposed inside the track drive assembly 101. Track shaft plates 102 are disposed on both sides above the cutting table 1, and the track shaft plates 102 are connected to the cutting table 1 by screws. A suspension track 1021 is disposed inside the track shaft plates 102, and track limiting plates 1011 are disposed at both ends of the track shaft plates 102, and the track limiting plates 1011 are connected to the cutting table 1 by screws. The gantry cutting frame 4 is slidably connected to the track shaft plates 102 via the track drive assembly 101. When the cutting table 1 is powered on, the laser cutting structure on the gantry cutting frame 4 performs a cutting operation on the base plate above the cutting plate 3. Multiple dust collection grids 104 are disposed inside the cutting table 1. A fan cabinet 103 is provided on one side of the dust collection grid 104. The fan cabinet 103 is used to realize the ventilation operation of the fan and can also perform secondary filtration of the airflow inside the fan duct to prevent the exhaust gas from containing a large amount of dust. A power supply box 106 is provided on the other side of the dust collection grid 104. During the cutting process, the fan inside the dust collection grid 104 starts to run, and the debris and dust generated during cutting are sucked into the dust collection grid 104 through the dust collection air channel 1041. This can prevent the debris generated during cutting from spreading in the processing area and achieve dust-free processing operation. A dust collection tray 105 is provided at the bottom of the cutting table 1. The dust collection tray 105 is equipped with pulleys 1051 at the bottom of the dust collection tray 105 and is slidably connected to the cutting table 1. The dust collection tray 105 is equipped with feet 1052 on all four sides. The feet 1052 are connected to the cutting table 1 by screws. After the cutting is completed, the dust collection tray 105 can be pulled out for cleaning.

[0033] To address the issue of timely cleaning of debris inside the enclosure, please refer to [link / reference needed]. Figure 2-3 This embodiment provides the following technical solution:

[0034] Dust suction grate 104 has dust suction ducts 1041 on both sides of its top and dust discharge ducts 1042 on both sides of its bottom. Dust and debris sucked into the dust suction grate 104 comes into contact with the baffle plate 1043. After most of the dust impacts the baffle plate 1043, the suction force of the fan decreases, and the dust on the baffle plate 1043 slides down to the damping gate 1044 area and is then discharged into the dust collection area through the dust discharge duct 1042 on one side. In the drawer panel 105, multiple unit fans 1046 are installed inside the dust collection grid frame 104. Each unit fan 1046 is connected to the fan housing 103 via pipes. Damping gates 1044 are installed on both sides above each unit fan 1046. One end of each damping gate 1044 is rotatably connected to the dust collection grid frame 104 via a damping coupling 1045. A partition plate 1043 is installed above the damping gate 1044, extending into the inner side of the dust collection duct 1041. The damping gates 1044... A side ramp 1047 is provided below the dust collection tray 105, extending diagonally above it. A small amount of debris and dust enters the area where the unit fan 1046 is located. When the damping gate 1044 is closed, an oblique cavity structure is formed between the damping gate 1044 and the unit fan 1046. At this time, the airflow generated by the fan enters the side ramp 1047 area along the surface of the damping gate 1044 and is discharged through the side ramp 1047. The debris and dust entering the unit fan 1046 area will enter the side slope 1047 along the airflow formed by the damping gate 1044 and the fan, and will eventually be discharged. When too much debris is sucked in, the gravity on the damping gate 1044 increases, and the gate rotates downward to open. At this time, the debris can be discharged directly through the side slope 1047. After the cutting is completed, the dust collection tray 105 can be pulled out for cleaning. This can avoid the blockage of the dust discharge window slot 1042 area due to excessive debris.

[0035] To address the dust generation issue during existing blade cutting processes, please refer to [link / reference]. Figure 3-6 This embodiment provides the following technical solution:

[0036] A light source 402 is installed at the bottom of the gantry cutting frame 4. Slides 401 are installed on both sides of the gantry cutting frame 4. A horizontal rail 4031 is installed on one side of the light source 402. The horizontal rail 4031 is connected to the gantry cutting frame 4 by screws. A support shaft 403 is installed below the horizontal rail 4031 and is slidably connected to the horizontal rail 4031. A laser cutting assembly 4032 is installed at the bottom of the support shaft 403. Compared with traditional blade cutting, the laser cutting assembly 4032 does not produce a large amount of cutting debris during the cutting process, and the debris is not affected by the blade. The centrifugal force effectively reduces dust generation. A toothed plate 302 is provided on the outer surface of the cutting table 3, and the toothed plate 302 is connected to the cutting table 3 by screws. Wheel boxes 301 are provided on both sides of the cutting table 3, and track wheels 3011 are installed inside the wheel boxes 301. A sensing module 3012 is installed on one side of the track wheel 3011, and the sensing module 3012 is connected to the wheel box 301 by a bracket. Lifting brackets 303 are provided at both ends of the gantry cutting frame 4, and the lifting brackets 303 are connected to the cutting preparation table 2 by screws. A cylinder 30 is installed on one side of the lifting bracket 303. 31. A biting shaft 3032 is provided above the cylinder 3031. The biting shaft 3032 is connected to the cutting table 3 by screws. A push rod is provided on the top of the cylinder 3031. A straightening slide sleeve 304 is provided on both sides of one end of the gantry cutting frame 4. A sleeve rail 202 is provided inside the cutting preparation table 2. The wheel box 301 is slidably connected to the sleeve rail 202 through the track wheel 3011. A straightening frame 204 is provided at one end of the sleeve rail 202. The straightening frame 204 is connected to the cutting preparation table 2 by screws. When the base plate is placed flat on the cutting table 3, the lifting brackets 303 at both ends lower the cutting table. The cutting table 3 is brought into contact with the rail 202, and the cutting table 3 is moved to the cutting processing table 1 through the rail 202. After the cutting table 3 is moved to the cutting processing table 1, it will be driven by the suspension rail 1021 contacting the wheel box 301. A control box 201 is provided on one side of the cutting preparation table 2, and an electrical box 203 is provided at the bottom of the cutting preparation table 2. A motor module 2031 is provided at one end of the electrical box 203. The motor module 2031 is meshed and rotated with the transmission gear 2032. The rail 202 is slidably connected to the cutting preparation table 2 through the transmission gear 2032.

[0037] This embodiment also proposes a method for implementing a dust-free cutting device for PVC wood-plastic flooring production, including the following steps:

[0038] Step 1: Place the base plate flat on top of the cutting table 3. At this time, the lifting brackets 303 at both ends will lower the cutting table so that the cutting table 3 contacts the rail 202. The cutting table 3 will be moved to the cutting processing table 1 through the rail 202. After the cutting table 3 moves to the cutting processing table 1, it will be driven by the suspension rail 1021 contacting the wheel box 301.

[0039] Step 2: After the cutting table 3 is completely moved and covers the cutting processing table 1, turn on the power of the cutting processing table 1. The bottom plate above the cutting table 3 is cut by the gantry cutting frame 4 and the laser cutting component 4032. During the cutting process, the fan inside the dust collection grid 104 is started and runs. The dust and dust generated during the cutting are sucked into the dust collection grid 104 through the dust collection duct 1041.

[0040] Step 3: The debris and dust sucked into the dust collection grid 104 will come into contact with the partition air plate 1043. Most of the debris will slide down the partition air plate 1043 to the damping gate 1044 area after hitting the partition air plate 1043. A small part of the debris and dust will enter the area where the unit fan 1046 is located. The debris that slides down to the damping gate 1044 area can be discharged into the dust collection tray 105 through the dust discharge window slot 1042. The debris and dust that enter the area of ​​the unit fan 1046 will enter the side slope slot 1047 along the airflow formed by the damping gate 1044 and the fan.

[0041] Step 4: When too much debris is sucked in, the weight on the damping gate 1044 increases, and the gate rotates downward to open. At this time, the debris can be discharged directly through the side ramp 1047. After the cutting is completed, the dust collection tray 105 can be pulled out for cleaning.

[0042] The working principle is as follows: the base plate is placed flat above the cutting table 3. At this time, the lifting brackets 303 at both ends lower the cutting table so that the cutting table 3 contacts the rail 202. The cutting table 3 is moved towards the cutting processing table 1 through the rail 202. After the cutting table 3 moves onto the cutting processing table 1, it will be driven by the suspension rail 1021 contacting the wheel box 301. After the cutting table 3 has completely moved and covered the cutting processing table 1, the power of the cutting processing table 1 is turned on. The gantry cutting frame 4 and the laser cutting component 4032 cut the base plate above the cutting table 3. During the cutting process, the fan inside the dust collection grid 104 starts running and sucks the debris and dust generated during cutting into the dust collection grid 104 through the dust collection duct 1041. Debris and dust drawn into the dust collection grid 104 will come into contact with the baffle plate 1043. Most of the debris will slide down the baffle plate 1043 to the damping gate 1044 area after impacting it. A small portion of the debris and dust will enter the area where the unit fan 1046 is located. The debris that slides down to the damping gate 1044 area can be discharged into the dust collection tray 105 through the dust discharge window slit 1042. The debris and dust that enter the area of ​​the unit fan 1046 will enter the side slope slit 1047 along the airflow formed by the damping gate 1044 and the fan. When the amount of debris drawn in is too large, the gravity on the damping gate 1044 increases, and the gate rotates downward to open. At this time, the debris can be discharged directly through the side slope slit 1047. After the cutting is completed, the dust collection tray 105 can be pulled out for cleaning.

At this time, the lifting brackets (303) at both ends will lower the cutting table so that the cutting table (3) contacts the rail (202). The cutting table (3) will be moved to the cutting processing table (1) through the rail (202). After the cutting table (3) moves to the cutting processing table (1), the suspension rail (1021) will contact the wheel box (301) for transmission operation. Step 2: After the cutting table (3) is completely moved and covers the cutting processing table (1), turn on the power of the cutting processing table (1) and cut the bottom plate above the cutting table (3) through the gantry cutting frame (4) and the laser cutting assembly (4032). During the cutting process, the fan inside the dust collection grid (104) starts running and sucks the debris and dust generated during the cutting into the dust collection grid (104) through the dust collection duct (1041). Step 3: The debris and dust sucked into the dust collection grid (104) will come into contact with the partition air plate (1043). Most of the debris will slide down the partition air plate (1043) to the damping gate (1044) area after hitting the partition air plate (1043). A small part of the debris and dust will enter the area where the unit fan (1046) is located. When the debris that slides down to the damping gate (1044) area is discharged into the dust collection tray (105) through the dust discharge window slot (1042), the debris and dust that enter the unit fan (1046) area will enter the side slope groove (1047) along the airflow formed by the damping gate (1044) and the fan. Step 4: When too much debris is sucked in, the weight on the damping gate (1044) increases, and the gate rotates downward to open. At this time, the debris can be discharged directly through the side ramp (1047). After the cutting is completed, the dust collection tray (105) can be pulled out for cleaning.
