Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic product processing, in particular to a glass fiber reinforced plastic product cutting device. Background Art

[0002] Glass fiber reinforced plastic products, referred to as FRP, are a polymer material made from glass fiber and synthetic resin through a composite process. This material has the advantages of high strength, high rigidity, corrosion resistance, and good insulation. It is widely used in construction, automobiles, electronics, aerospace and other fields.

[0003] In the processing of glass fiber reinforced plastic products, it is necessary to cut them. When cutting, cutting equipment is needed. In the related technology, for example, Chinese patent CN219968160U discloses a cutting device for producing glass fiber reinforced plastics. When the cutting device for producing glass fiber reinforced plastics is in use, a cutting groove is provided on the workbench, and the cutting groove is located directly below the cutting knife. A collecting box is provided below the cutting groove. The bottom plate of the collecting box is inclined. A movable cover that can be opened is provided on the side wall of the lower side of the bottom plate of the collecting box. The waste generated by the cutting knife falls directly into the collecting box. The movable cover can be opened after multiple cutting operations to clean the waste generated by cutting in the collecting box at one time. A dust cover is also provided on the cutting knife. When cutting, the dust cover is as close to the workbench as possible without affecting the movement of the cutting knife. Most of the dust generated by the cutting knife during cutting is blocked by the dust cover and falls into the collecting box through the cutting groove after the cutting knife stops working.

[0004] Although the above-mentioned glass fiber reinforced plastic cutting device can cut glass fiber reinforced plastic products, it is found in actual use that since the dust cover only covers the upper part of the cutting knife, and the cutting knife mainly uses the lower part to cut the glass fiber reinforced plastic products, during the entire process of cutting the glass fiber reinforced plastic products, there is a gap between the dust cover and the workbench for most of the time, which causes the dust containing glass fiber powder and resin powder generated when the glass fiber reinforced plastic products are cut to escape into the air, which is easy to cause air pollution and affect the health of workers. Summary of the invention

[0005] Based on this, it is necessary to provide a glass fiber reinforced plastic product cutting device to address the problems of large dust, easy air pollution and impact on workers' health during the current glass fiber reinforced plastic product cutting process.

[0041] like Figures 1 to 7 As shown, a glass fiber reinforced plastic product cutting device provided by an embodiment of the present invention is used for cutting materials, wherein the materials are set as plates and are set as glass fiber reinforced plastic products; the glass fiber reinforced plastic product cutting device is set to include a machine base 1, a circular saw blade 2, a dust suction mechanism, a conveying mechanism and a sealing mechanism 5, wherein the circular saw blade 2 is set on the machine base 1 and can rotate to cut the materials; the dust suction mechanism is set on the machine base 1 and includes a dust suction hood 31 and a suction part, and the dust suction hood 31 is set on the outside of the circular saw blade 2; the material passes through the dust suction hood 31 when cutting; the suction part is connected to the dust suction hood 31 and is configured to be able to suck the air in the dust suction hood 31; the conveying mechanism is configured to be able to convey the materials; the conveying mechanism is configured to include a conveyor belt 41, the conveyor belt 41 forms a closed conveying loop on the machine base 1; there are two conveyor belts 41, which are respectively arranged on both sides of the dust hood 31; the sealing mechanism 5 is configured to seal the gap between the material and the dust hood 31; the sealing mechanism 5 is configured to include two elastic parts 51 and a plurality of pressure rollers 52, and the elastic part 51 is arranged on the conveyor belt 41; the pressure roller 52 is arranged on the machine base 1, and the bottom of the pressure roller 52 is flush with the top of the elastic part 51; the plurality of pressure rollers 52 are divided into two groups, and the two groups of pressure rollers 52 are respectively arranged on both sides of the dust hood 31, and can be pressed on the top of the material when in use to cause the elastic part 51 to be elastically compressed; the length of the material is greater than or equal to the distance between the two nearest pressure rollers 52 on both sides of the dust hood 31.

[0042] Specifically in this embodiment, Figure 1 and Figure 2 As shown, the base 1 is configured as an L-shaped structure and has a frame portion and a box portion, wherein the frame portion is configured as a strip structure, and the frame portion is disposed on the top of the box portion during installation, and extends along the length direction of the box portion and is disposed on the right side.

[0043] To facilitate installation and drive the circular saw blade 2 to rotate, Figure 4As shown, a first drive motor 21 is arranged on the top of the box part of the base 1, the first drive motor 21 and the frame part are located on the same side, and the motor shaft of the first drive motor 21 is horizontal and extends along the width direction of the box part; the circular saw blade 2 is coaxial and fixed on the motor shaft of the first drive motor 21 during installation.

[0044] like Figure 2 As shown, the dust hood 31 is configured as a box structure and is fixed to the frame portion of the base 1 during installation, and an air suction port 3101 is provided at the top of the dust hood 31; the suction portion can be configured as an air pump, and the air suction end of the air pump is connected to the air suction port 3101 through a pipeline, and the exhaust end is connected to the external environment.

[0045] It is understandable that in order to prevent the dust inside the dust hood 31 from entering the vacuum pump and affecting the service life of the vacuum pump, a pre-filter can be installed between the vacuum pump and the vacuum port 3101 so that the dust in the air inside the dust hood 31 can be filtered out by the pre-filter before the air enters the vacuum pump.

[0046] It is understandable that the vacuum pump can be configured as a rotary vane vacuum pump.

[0047] like Figure 2 As shown, the conveyor belt 41 is configured as an annular structure, and is horizontally arranged at the top of the box part of the base 1 during installation, and conveys along the length direction parallel to the box part of the base 1, and two conveyor belts 41 are arranged at intervals along the length direction of the box part of the base 1, and are symmetrically arranged about the dust hood 31, and the end of the conveyor belt 41 close to the dust hood 31 is inserted into the interior of the dust hood 31.

[0048] In order to facilitate supporting the conveyor belt 41, the glass fiber reinforced plastic product cutting device is configured to further include four first bearing seats 11, four second bearing seats 12 and four rotating rollers 411, such as Figure 5As shown, four first bearing seats 11, four second bearing seats 12 and four rotating rollers 411 are all arranged on the top of the box structure of the machine base 1, the four first bearing seats 11 are divided into two groups, the two groups are respectively arranged at the left and right ends of the box structure of the machine base 1, and the two first bearing seats 11 in the same group are arranged at intervals along the width direction of the box structure of the machine base 1; the four second bearing seats 12 are divided into two groups, the two groups are arranged close to the middle of the box structure of the machine base 1, and the two second bearing seats 12 in the same group are arranged at intervals along the width direction of the box structure of the machine base 1, and are flush with the first bearing seats 11; two rotating rollers 411 are coaxially inserted into the two first bearing seats 11 in the same group during installation, and the other two rotating rollers 411 are coaxially inserted into the two second bearing seats 12 in the same group during installation; the conveyor belt 41 is connected to the two adjacent rotating rollers 411 on the left side or the two adjacent rotating rollers 411 on the right side during installation.

[0049] To facilitate installation of the conveyor belt 41, Figure 2 As shown, the dust hood 31 is configured as a T-shaped structure, and the front and rear side walls of the small end of the dust hood 31 are configured as arc-shaped and open structures.

[0050] like Figure 1 As shown, the elastic portion 51 is configured as an annular belt structure, and is fixedly sleeved on the outer side of the conveyor belt 41 during installation. The elastic portion 51 can be made of an elastic material, such as sponge, rubber, nylon, etc., so as to be able to undergo elastic deformation; the pressure roller 52 is arranged on the frame portion of the base 1 during installation, and is extended along the width direction of the box portion of the base 1. The number of the pressure rollers 52 can be four, and they are evenly divided into two groups, one group of pressure rollers 52 is arranged on the front side of the dust hood 31, and the other group of pressure rollers 52 is arranged on the rear side of the dust hood 31; as shown in FIG. Figure 3 As shown, the pressure roller 52 is located above the elastic portion 51 and is tangentially arranged with the elastic portion 51 . The top of the elastic portion 51 is flush with the top of the opening of the small end side wall of the dust hood 31 .

[0051] To facilitate installation of the pressure roller 52, Figure 3 As shown, four third bearing seats 13 are arranged on the frame part, and the four third bearing seats 13 are divided into two groups, one group of third bearing seats 13 is arranged on the front side of the dust cover 31, and the other group of third bearing seats 13 is arranged on the rear side of the dust cover 31; when installing, the pressure roller 52 is arranged so that one end of the frame part facing the machine base 1 is coaxially inserted on the third bearing seat 13, and the other end is suspended.

[0052] During use, first start the first drive motor 21, the first drive motor 21 drives the circular saw blade 2 to rotate, and then start the vacuum pump, the vacuum pump sucks the air in the dust hood 31, and then drives the conveyor belt 41 to move, so that the conveyor belt 41 forms a closed conveying loop; then place the material on the conveyor belt 41 located on the front side of the dust hood 31, and the conveyor belt 41 simultaneously drives the material to move toward the direction close to the dust hood 31, and then enters the dust hood 31 and is cut by the circular saw blade 2. The cut part of the material is transported by the conveyor belt 41 to the conveyor belt 41 located on the rear side of the dust hood 31, thereby completing the cutting and conveying of the material with the cooperation of the two conveyor belts 41.

[0053] During the material movement, as the front conveyor belt 41 is conveyed, when the material moves between the front pressure roller 52 and the front elastic portion 51, the material moves downward under the pressure of the front pressure roller 52, and the front elastic portion 51 is simultaneously compressed. Since the bottom of the front pressure roller 52 is flush with the top of the front elastic portion 51, the material moves downward by its own thickness under the pressure of the front pressure roller 52, so that the top of the material is just flush with the top of the opening of the small end front side wall of the dust hood 31, so as to reduce the opening size of the small end front side wall of the dust hood 31; at the same time, the top of the front elastic portion 51 that is not compressed is flush with the top of the opening of the small end front side wall of the dust hood 31, so as to further reduce the opening size of the small end front side wall of the dust hood 31, thereby improving the sealing of the dust hood 31 and reducing the probability of dust-containing air escaping from the inside of the dust hood 31 through the opening of the small end front side wall of the dust hood 31 to the external environment.

[0054] When the material has not moved onto the rear conveyor belt 41, the top of the rear elastic portion 51 is flush with the top of the opening of the small rear side wall of the dust hood 31, so as to reduce the opening size of the small rear side wall of the dust hood 31; when the material moves onto the rear conveyor belt 41, the material simultaneously compresses the rear elastic portion 51, and since the material moves downward by its own thickness, the top of the material is just flush with the top of the opening of the small rear side wall of the dust hood 31, so as to reduce the opening size of the small rear side wall of the dust hood 31; at the same time, the top of the uncompressed rear elastic portion 51 is flush with the top of the opening of the small rear side wall of the dust hood 31, so as to further reduce the opening size of the small rear side wall of the dust hood 31, thereby improving the sealing of the dust hood 31 and reducing the probability of dust-containing air escaping from the inside of the dust hood 31 through the opening of the small front side wall of the dust hood 31 to the external environment.

[0055] During the material cutting process, the dust generated including glass fiber powder and resin powder will escape into the dust hood 31 and be sucked away along with the air, thereby reducing the dust from escaping to the outside of the dust hood 31 and causing air pollution, and reducing the impact on workers' health.

[0056] It can be understood that in order to ensure that the material can normally press down the elastic parts 51 on both sides of the dust hood 31 and avoid the problem that when the material is in the dust hood 31, the elastic part 51 on the rear side cannot be smoothly and quickly compressed by the material's own weight, it is set to have a suitable length of the material, and the suitable length can be set to be greater than or equal to the distance between the two nearest pressure rollers 52 on both sides of the dust hood 31; during use, with the transmission of the front conveyor belt 41, since the length of the material is greater than or equal to the distance between the two nearest pressure rollers 52 on both sides of the dust hood 31, when the front end of the material first enters the interior of the dust hood 31 from the front side wall opening of the dust hood 31, and then moves from the rear side wall opening of the dust hood 31 to the rear conveyor belt 41 after being cut by the circular saw blade 2, the rear end of the material is still located on the front conveyor belt 41 at this time, and is pressed by the front pressure roller 52, so that the material is still in a downward pressure state, so that the elastic part 51 on the rear side can be pressed down normally.

[0057] In a further embodiment, when the existing circular saw blade 2 is cutting materials, the thicker the material is, the more contact there is between the non-cutting area of ​​the circular saw blade 2 and the material while the position of the circular saw blade 2 remains unchanged, causing the non-cutting area of ​​the circular saw blade 2 to not only be more severely worn but also to generate more heat, which affects the strength of the cutting area of ​​the circular saw blade 2 and the service life of the circular saw blade 2. To solve this problem, the glass fiber reinforced plastic product cutting device is configured to also include a constant distance mechanism, which is configured to keep the distance between the lowest point of the circular saw blade 2 and the bottom of the material unchanged when the thickness of the material changes.

[0058] When cutting glass fiber reinforced plastic products of different thicknesses, the distance between the lowest point of the circular saw blade 2 and the bottom of the material is kept constant through the constant distance mechanism. On the one hand, it helps to reduce the wear of the non-cutting area of ​​the circular saw blade 2 and reduce the heat generation of the circular saw blade 2. On the other hand, the glass fiber reinforced plastic products can be cut at a higher linear speed, which is beneficial to improve the cutting efficiency.

[0059] In a further embodiment, the constant distance mechanism is configured to include a bracket 61 and an elastic member, the bracket 61 is configured to support the circular saw blade 2, and when in use, the top is flush with the top of the elastic part 51 and is pushed against the bottom of the material; the elastic member is connected between the bracket 61 and the base 1, and under the action of the elastic member, the circular saw blade 2 has a tendency to move away from the base 1.

[0060] Specifically in this embodiment, Figure 5As shown, the bracket 61 is set to a "I"-shaped structure and extends along the length direction of the box structure parallel to the base 1. The two ends of the bracket 61 correspond to the two elastic parts 51 respectively; the first drive motor 21 is set at the top of the bracket 61 during installation and is located in the middle; the elastic member is set to a compression spring 62, such as Figure 4 As shown, during installation, the top end of the compression spring 62 is fixedly connected to the bottom of the bracket 61 , and the bottom end is fixedly connected to the top of the box structure of the base 1 . Under the action of the compression spring 62 , the circular saw blade 2 tends to move upward.

[0061] During use, since the bracket 61 pushes against the bottom of the material, when the material moves downward by the thickness of the material itself under the pressure of the pressure roller 52, the material synchronously drives the bracket 61 to move downward by the thickness of the material itself, the compression spring 62 is compressed and stored, and the bracket 61 synchronously drives the circular saw blade 2 to move downward by the thickness of the material itself, so that when the material is cut by the circular saw blade 2, no matter how thick the material is, the distance between the lowest point of the circular saw blade 2 and the bottom of the material can always remain unchanged, thereby ensuring that the circular saw blade 2 always contacts the material with the same non-cutting area, and after the non-cutting area becomes thinner, the probability or frequency of contact between the non-cutting area and the material will decrease, while reducing further wear and heat generation, while other non-cutting areas remain unchanged, so that the overall non-cutting area has less wear and less heat generation, ensuring that the circular saw blade 2 always has higher strength and service life, and on the other hand, ensuring that the circular saw blade 2 always cuts the material with a cutting area closer to the material, and the cutting area is farther from the axis of the circular saw blade 2, so that the contact position between the cutting area and the material has a larger relative linear velocity, thereby improving the cutting efficiency.

[0062] In a further embodiment, in order to reduce the wear on the material, a support roller 63 is provided on the bracket 61. The support roller 63 can rotate on its own and is in contact with the bottom of the material when in use.

[0063] Specifically in this embodiment, Figure 7 As shown, the support roller 63 is horizontally arranged on the bracket 61 and extends along the belt width direction of the conveyor belt 41.

[0064] During use, the provision of the support roller 63 changes the friction between the bracket 61 and the material from sliding friction to rolling friction, thereby reducing the wear on the bottom of the material.

[0065] In other embodiments, in order to improve the dust removal effect, a groove 5101 is provided on the elastic portion 51 , and the groove 5101 passes through the material and is connected to the dust hood 31 .

[0066] Specifically in this embodiment, Figure 1As shown, the groove 5101 is configured as an annular structure and is coaxially opened on the outer belt surface of the elastic portion 51 . There may be a plurality of grooves 5101 , which are arranged at equal intervals along the belt width direction of the elastic portion 51 .

[0067] When in use, the arrangement of the grooves 5101 allows air to circulate through the bottom of the material, thereby helping to improve the dust removal effect.

[0068] In other embodiments, the conveying mechanism is configured to further include a driving component, and the driving component is configured to provide a driving force for the conveyor belt 41 to form a closed conveying loop.

[0069] Specifically in this embodiment, the driving assembly is configured to include a second driving motor 421, a first belt 422, a first pulley, a second pulley 423 and a second belt 424. Figure 2 As shown, the second drive motor 421 is inserted into the box structure of the base 1 during installation and is located on the same side as the frame part. The motor shaft of the second drive motor 421 is horizontal and extends along the width direction of the box structure of the base 1. The first pulley is fixedly sleeved on the motor shaft of the second drive motor 421 during installation. Figure 5 As shown, there are two second pulleys 423, which are fixedly sleeved on the two rotating rollers 411 located in the middle during installation and are located on the same side as the frame part. The first belt 422 is simultaneously driven sleeved on the first pulley and one of the second pulleys 423 during installation, and the second pulley 423 is driven sleeved on the two second pulleys 423 during installation.

[0070] When in use, start the second drive motor 421, the second drive motor 421 drives the first pulley to rotate, the first pulley drives the first belt 422 to move, and one of the second pulleys 423 follows. The second pulley 423 drives the rotating roller 411 on which it is located to rotate on one hand, and the rotation of the rotating roller 411 synchronously drives the conveyor belt 41 thereon to move; on the other hand, it drives the second belt 424 to move, and the other second pulley 423 follows. The second pulley 423 drives the rotating roller 411 on which it is located to rotate on one hand, and the rotation of the rotating roller 411 synchronously drives the conveyor belt 41 thereon to move, so that the two conveyor belts 41 are transported in the same direction.

[0071] In other embodiments, to improve cutting efficiency, a plurality of circular saw blades 2 may be provided, and the plurality of circular saw blades 2 are arranged at equal intervals along the axial direction of the motor shaft of the first drive motor 21 so as to be able to cut the material into multiple strip portions at one time.

[0072] In order to allow adjacent circular saw blades 2 to be arranged at intervals, a separation ring 22 is sleeved on the motor shaft of the first drive motor 21 , and the separation ring 22 is located between adjacent circular saw blades 2 .

[0073] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
