Description

Technical Field

[0001] The present application relates to the field of plate cutting equipment, and in particular to a sawing machine for cutting plastic plates. Background Art

[0002] A sawing machine is a machine tool used to cut metal, wood or other materials. It usually consists of a fixed base, a movable saw frame and a saw tooth. The sawing machine cuts the workpiece through the reciprocating or circular motion of the saw teeth. The speed and feed rate of the saw teeth can be adjusted as needed to obtain the desired cutting effect and accuracy. Sawing machines are widely used in machinery manufacturing, construction, furniture manufacturing and other fields.

[0003] In the related art, a large amount of waste is generated during the material cutting process of a sawing machine. As the material is continuously cut, the waste will gradually accumulate around the saw teeth, and then the waste will affect the saw teeth's cutting of the material. The common method of cleaning up the waste is that after the material is cut, the staff will centrally process the waste. This treatment method can only process the waste after the material is cut, but during the saw teeth's cutting process, the waste will affect the saw teeth's cutting of the material.

[0004] Therefore, there is an urgent need for a sawing machine that can simultaneously process waste materials around the saw teeth while cutting materials. Utility Model Content

[0005] The present application provides a sawing machine for cutting plastic plates, the purpose of which is to process waste materials simultaneously while cutting materials, thereby effectively solving the problem of waste materials affecting the cutting of the sawing machine during the material cutting process.

[0006] The present application provides a sawing machine for cutting plastic sheets, which adopts the following technical solution:

[0007] A sawing machine for cutting plastic plates, comprising a frame, a feeding frame and a cutting tooth rotatably mounted on one side of the feeding frame, wherein the feeding frame is used to transport the material to be cut to the cutting tooth, and the cutting tooth is used to cut the material;

[0008] The feed rack is located on one side of the cutting tooth and is additionally provided with a cleaning component, the cleaning component includes a cleaning tooth and a cleaning plate, the cleaning tooth is rotatably mounted on the feed rack, and the cleaning tooth and the cutting tooth are located on the same side of the feed rack, the cleaning plate is located at the cutting tooth and the bottom of the cleaning tooth, the cleaning tooth and the cleaning plate are used to clean the waste material around the cutting tooth.

[0009] By adopting the above technical solution, the waste generated by the cutting teeth in the process of cutting materials will gradually accumulate on the peripheral side of the cutting teeth. The cleaning component can clean up the waste accumulated on the peripheral side of the cutting teeth, and then the cleaning component can be used to process the waste simultaneously while the cutting teeth are cutting materials, thereby effectively solving the problem of waste affecting the cutting of the cutting teeth during the cutting process of the saw machine.

[0010] Preferably, the cleaning plate comprises an integrally formed first plate body and a second plate body, the cleaning teeth are located above the first plate body, the cutting teeth are located above the second plate body, and the first plate body and the second plate body are both inclined;

[0011] The height of the first plate body close to one end of the second plate body is lower than that of the other end thereof;

[0012] The height of the second plate body close to one end of the first plate body is higher than that of the other end thereof.

[0013] By adopting the above technical solution, when the cutting teeth are cutting the material, the waste generated will gradually accumulate on the first plate body. When the waste accumulates to a certain extent on the first plate body, it will affect the cutting of the material by the cutting teeth. At this time, the cleaning teeth are opened and rotated. While the cleaning teeth are rotating, the waste on the first plate body will be gradually discharged to the second plate body. Since the second plate body is inclined, after the cleaning teeth discharge the waste to the second plate body, the waste can automatically flow to the bottom of the second plate body under the action of its own gravity.

[0014] In this arrangement, cleaning teeth are installed above the first plate body. When waste materials accumulate on the first plate body, the cleaning teeth are used to clean the waste materials on the first plate body, thereby effectively preventing the waste materials from accumulating on the first plate body. At the same time, the second plate body is arranged in an inclined state. When waste materials fall onto the second plate body, the waste materials will automatically flow to the bottom of the second plate body, thereby effectively preventing the waste materials from accumulating on the second plate body, thereby effectively preventing the waste materials from accumulating on the surrounding sides of the cutting teeth, thereby effectively solving the problem that waste materials affect the cutting of the cutting teeth during the material cutting process of the sawing machine.

[0015] Preferably, a discharge box is installed at one end of the second plate body away from the first plate body, a feed port is provided on a side of the discharge box close to the second plate body, and a discharge port is provided on a side of the discharge box away from the second plate body, the feed port and the discharge port are connected, and one end of the second plate body away from the first plate body extends into the discharge box through the feed port;

[0016] A material receiving box is placed on one side of the material discharge box, and the material receiving box is located at the material discharge port and is communicated with the material discharge port.

[0017] By adopting the above technical solution, after the cleaning teeth discharge the waste on the first plate body to the second plate body, the waste is discharged into the discharge box through the second plate body, and finally concentrated into the receiving box through the discharge port for collection.

[0018] The discharge box and the receiving box can collect the waste materials in a centralized manner while the cleaning teeth are cleaning the waste materials, thereby facilitating the subsequent treatment of the waste materials.

[0019] Preferably, the feed port is opened in the middle of the discharge box, the discharge port is opened at the bottom of the discharge box, a vibration component is added in the discharge box, and the vibration component is located between the feed port and the discharge port.

[0020] By adopting the above technical solution, when the waste is discharged into the discharge box through the second plate, the waste will fall onto the vibration component and drive the vibration component to vibrate. During the vibration process, the vibration component gradually drives the waste to move in the direction close to the discharge port, and then the vibration component effectively prevents the waste from accumulating in the discharge box, thereby helping to discharge the waste in the discharge box into the receiving box.

[0021] Preferably, the vibration assembly includes a vibration plate and a vibration spring, the vibration plate is obliquely arranged between the feed port and the discharge port; the vibration spring is installed in a vertical direction between the bottom of the vibration plate and the bottom of the discharge box.

[0022] By adopting the above technical solution, when the waste is discharged into the discharge box through the second plate body, it will directly fall on the top of the vibration plate. As the waste gradually increases, the weight of the waste itself will compress the vibration spring at the bottom of the vibration plate. As the weight of the waste continues to change, the compression amount of the vibration spring will gradually change, and then the vibration plate will be driven to vibrate through the vibration spring. During the vibration process, the vibration plate drives the waste to gradually slide in the direction close to the discharge port. At the same time, the vibration plate itself is inclined, which is more conducive to discharging the waste into the receiving box for centralized collection.

[0023] Preferably, a fan is installed in the discharge box, and the fan is located on the top of the vibration plate.

[0024] By adopting the above technical solution, when a large amount of waste is discharged onto the vibration plate, a fan is used to blow the waste on the vibration plate, which helps the waste on the vibration plate to flow from the vibration plate to the discharge port more quickly and efficiently, thereby helping to speed up the collection of the waste.

[0025] Preferably, a dustproof plate is installed along the length direction of the second plate body on one side away from the feeding rack.

[0026] By adopting the above technical solution, the first plate body and the second plate body are effectively shielded by the dustproof plate, thereby effectively preventing the waste generated by the cutting teeth in the process of cutting the material from flying around, which is beneficial to protecting the working environment of the workshop.

[0027] Preferably, the surfaces of the first plate body and the second plate body are both polished and smooth.

[0028] By adopting the above technical solution, the surfaces of the first plate body and the second plate body after smooth grinding are both smooth, and waste materials are not easy to accumulate on the first plate body and the second plate body when falling on them.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The waste generated by the cutting teeth in the process of cutting materials will gradually accumulate on the peripheral side of the cutting teeth. The cleaning component can clean up the waste accumulated on the peripheral side of the cutting teeth, and then use the cleaning component to process the waste while the cutting teeth are cutting materials, thereby effectively solving the problem that the waste affects the cutting of the cutting teeth during the sawing process;

[0031] 2. After the waste is discharged into the discharge box through the second plate, the waste will fall onto the vibration component and drive the vibration component to vibrate. During the vibration process, the vibration component gradually drives the waste to move toward the discharge port, thereby effectively preventing the waste from accumulating in the discharge box through the vibration component, thereby helping to discharge the waste in the discharge box into the receiving box;

[0032] 3. When the waste is discharged into the discharge box through the second plate body, it will fall directly on the top of the vibration plate. As the waste gradually increases, the weight of the waste itself will compress the vibration spring at the bottom of the vibration plate. As the weight of the waste continues to change, the compression amount of the vibration spring will gradually change, and then the vibration plate will be driven to vibrate through the vibration spring. During the vibration process, the vibration plate drives the waste to gradually slide in the direction close to the discharge port. At the same time, the vibration plate itself is tilted, which is more conducive to discharging the waste into the receiving box for centralized collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0039] Example:

[0040] The present application embodiment discloses a sawing machine for cutting plastic sheets, referring to Figure 1 and Figure 2 , comprising a frame 1, a feeding frame 2 and a cutting tooth 3 installed on one side of the feeding frame 2, the top of the cutting tooth 3 vertically extending upward from the top of the feeding frame 2, the feeding frame 2 is used to transport the material to be cut to the cutting tooth 3, the cutting tooth 3 is driven by a corresponding motor to rotate, and when the material passes through the cutting tooth 3, the cutting tooth 3 cuts the material. In this embodiment, the cutting tooth 3 rotates counterclockwise.

[0041] At the same time, refer to Figure 1 and Figure 2 A material cleaning component 4 is also provided on one side of the feeding frame 2 where the cutting teeth 3 are installed. The waste generated by the cutting teeth 3 in the process of cutting materials will gradually accumulate around the cutting teeth 3. The material cleaning component 4 can clean up the waste accumulated around the cutting teeth 3, and then the material cleaning component 4 can be used to process the waste simultaneously while the cutting teeth 3 are cutting materials, thereby effectively solving the problem that the waste affects the cutting of the cutting teeth 3 in the process of cutting materials on the sawing machine.

[0042] Specifically, refer to Figure 1 and Figure 2The cleaning assembly 4 includes a cleaning tooth 41 and a cleaning plate 42. The cleaning tooth 41 is installed on the feed rack 2 and is located on the same side of the feed rack 2 as the cutting tooth 3. The feed rack 2 is also equipped with a motor for driving the cleaning tooth 41 to rotate. The cleaning tooth 41 rotates clockwise. The gear of the cleaning tooth 41 is smaller than the cutting tooth 3, and the top height of the cleaning tooth 41 is lower than the top of the feed rack 2; the cleaning plate 42 is integrally welded to the feed rack 2 along the length direction of the feed rack 2, and the cleaning plate 42 is located below the cutting tooth 3 and the cleaning tooth 41.

[0043] Specifically, refer to Figure 1 and Figure 2 The cleaning plate 42 includes an integrally formed first plate body 421 and a second plate body 422. The first plate body 421 and the second plate body 422 are both rectangular plates. The cleaning tooth 41 is located above the first plate body 421, and the shortest distance between the gear of the cleaning tooth 41 and the first plate body 421 is in a connected state. The cutting tooth 3 is located above the end of the second plate body 422 close to the first plate body 421.

[0044] In this embodiment, the second plate body 422 is disposed obliquely, and the height of one end of the second plate body 422 close to the first plate body 421 is higher than the height of the other end thereof.

[0045] Specifically, when the cutting teeth 3 are cutting the material, the waste material generated will gradually accumulate on the first plate 421. When the waste material accumulates to a certain extent on the first plate 421, it will affect the cutting of the material by the cutting teeth 3. At this time, the cleaning teeth 41 are opened and rotated. While the cleaning teeth 41 are rotating, the waste material on the first plate 421 will be gradually discharged to the second plate 422. Since the second plate 422 is inclined, after the cleaning teeth 41 discharge the waste material to the second plate 422, the waste material can automatically flow to the bottom of the second plate 422 under the action of its own gravity.

[0046] In this arrangement, a cleaning tooth 41 is installed above the first plate body 421. When waste materials accumulate on the first plate body 421, the cleaning tooth 41 is used to clean the waste materials on the first plate body 421, thereby effectively preventing the waste materials from accumulating on the first plate body 421. At the same time, the second plate body 422 is arranged to be inclined. When waste materials fall onto the second plate body 422, the waste materials will automatically flow to the bottom of the second plate body 422, thereby effectively preventing the waste materials from accumulating on the second plate body 422, thereby effectively preventing the waste materials from accumulating on the surrounding side of the cutting tooth 3, thereby effectively solving the problem that waste materials affect the cutting of the cutting tooth 3 during the material cutting process of the sawing machine.

[0047] In this embodiment, the first plate body 421 is also inclined, and one end of the first plate body 421 close to the second plate body 422 is lower than the other end thereof. At the same time, the surfaces of the first plate body 421 and the second plate body 422 are both polished and smooth. The surfaces of the first plate body 421 and the second plate body 422 that have been polished and smooth are both smooth. When waste falls onto the first plate body 421 and the second plate body 422, it is not easy to accumulate on the first plate body 421 and the second plate body 422.

[0048] Further, refer to Figure 2 and Figure 3 A discharge box 5 is installed at one end of the second plate body 422 away from the first plate body 421. The discharge box 5 is in a rectangular shape and is hollow inside. A feed port 6 is provided on the side of the discharge box 5 close to the second plate body 422, and a discharge port 7 is provided on the side of the discharge box 5 away from the second plate body 422. The feed port 6 and the discharge port 7 are connected. The feed port 6 is opened in the middle of the discharge box 5, and the discharge port 7 is opened at the bottom of the discharge box 5, and the end of the second plate body 422 away from the first plate body 421 extends into the discharge box 5 through the feed port 6; at the same time, a receiving box 8 is placed on one side of the discharge box 5, and the receiving box 8 is located at the discharge port 7 of the discharge box 5, and the top of the receiving box 8 is open and keeps connected with the discharge port 7.

[0049] After the cleaning teeth 41 discharge the waste on the first plate 421 onto the second plate 422 , the waste is discharged into the discharge box 5 through the second plate 422 , and finally collected into the receiving box 8 through the discharge port 7 .

[0050] The discharge box 5 and the receiving box 8 can collect the waste materials in a centralized manner while the cleaning teeth 41 clean the waste materials, thereby facilitating the subsequent treatment of the waste materials.

[0051] Further, refer to Figure 2 and Figure 3 A vibration component 9 is added to the discharge box 5. When the waste is discharged into the discharge box 5 through the second plate 422, the waste will fall onto the vibration component 9 and drive the vibration component 9 to vibrate. During the vibration process, the vibration component 9 gradually drives the waste to move toward the discharge port 7, and then the vibration component 9 effectively prevents the waste from accumulating in the discharge box 5, thereby helping to discharge the waste in the discharge box 5 into the receiving box 8.

[0052] Specifically, refer to Figure 2 and Figure 3The vibration assembly 9 includes a vibration plate 91 and a vibration spring 92. The vibration plate 91 is in a rectangular shape and is obliquely installed in the discharge box 5. One side of the vibration plate 91 is installed at the feed port 6 of the discharge box 5, and the other side of the vibration plate 91 is installed at the discharge port 7 of the discharge box 5. The vibration spring 92 is installed between the bottom of the vibration plate 91 and the bottom of the discharge box 5 in the vertical direction. In this embodiment, a plurality of vibration springs 92 are provided, and the plurality of vibration springs 92 are evenly spaced along the length direction of the vibration plate 91.

[0053] When the waste is discharged into the discharge box 5 through the second plate body 422, it will directly fall on the top of the vibration plate 91. As the waste gradually increases, the weight of the waste itself will compress the vibration spring 92 at the bottom of the vibration plate 91. As the weight of the waste continues to change, the compression amount of the vibration spring 92 will gradually change, and then the vibration spring 92 will drive the vibration plate 91 to vibrate. During the vibration process, the vibration plate 91 drives the waste to gradually slide in the direction close to the discharge port 7. At the same time, the vibration plate 91 itself is inclined, which is more conducive to discharging the waste into the receiving box 8 for centralized collection.

[0054] Further, refer to Figure 2 and Figure 3 A fan 10 is installed in the discharge box 5, and the fan 10 is located directly above the vibration plate 91. When a large amount of waste is discharged onto the vibration plate 91, the fan 10 is used to blow the waste on the vibration plate 91, which helps the waste on the vibration plate 91 to flow from the vibration plate 91 to the discharge port 7 more quickly and efficiently, thereby helping to speed up the collection of the waste.

[0055] Further, refer to Figure 2 and Figure 4 A dustproof plate 11 is installed along the length direction of the second plate body 422 on one side away from the feeding rack 2. The dustproof plate 11 is in the shape of a rectangular plate. The dustproof plate 11 is used to effectively shield the second plate body 422, thereby effectively preventing the waste generated by the cutting teeth 3 during the cutting process of the material from flying around, which is beneficial to protecting the working environment of the workshop.

[0056] The implementation principle of a sawing machine for cutting plastic plates in the embodiment of the present application is as follows:

[0057] When the cutting teeth 3 are cutting the material, the waste material generated will gradually accumulate on the first plate 421. When the waste material accumulates to a certain extent on the first plate 421, it will affect the cutting of the material by the cutting teeth 3. At this time, the cleaning teeth 41 are opened and rotated. While the cleaning teeth 41 are rotating, the waste material on the first plate 421 will be gradually discharged to the second plate 422. Since the second plate 422 is inclined, after the cleaning teeth 41 discharge the waste material to the second plate 422, the waste material will automatically flow to the bottom of the second plate 422 under the action of its own gravity.

[0058] In this arrangement, a cleaning tooth 41 is installed above the first plate body 421. When waste materials accumulate on the first plate body 421, the cleaning tooth 41 is used to clean the waste materials on the first plate body 421, thereby effectively preventing the waste materials from accumulating on the first plate body 421. At the same time, the second plate body 422 is arranged to be inclined. When waste materials fall onto the second plate body 422, the waste materials will automatically flow to the bottom of the second plate body 422, thereby effectively preventing the waste materials from accumulating on the second plate body 422, thereby effectively preventing the waste materials from accumulating on the surrounding side of the cutting tooth 3, thereby effectively solving the problem that waste materials affect the cutting of the cutting tooth 3 during the material cutting process of the sawing machine.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
