Description

Technical Field

[0001] This utility model relates to the field of glass fiber cotton processing technology, and in particular to a glass fiber cotton cutting device. Background Technology

[0002] After the fiberglass wool board or felt is manufactured, it needs to be cut into shape by cutting equipment in order to meet transportation or customer needs. The cutting process is divided into several steps. Generally, the edges are cut before winding. After the edges are cut, the board is wound or transported to another machine for the next cutting step.

[0003] In related technologies, reference can be made to Chinese utility model patent CN219426944U, which discloses a fully automatic cutting device, including a conveyor belt, a cross-cutting mechanism above the conveyor belt, and a longitudinal cutting mechanism on one side of the cross-cutting mechanism above the conveyor belt. By setting up the longitudinal cutting mechanism, all the burr edges of the freshly produced glass wool board are neatly trimmed. Then, the conveyor belt transports the glass wool board with burr-free edges to the cross-cutting mechanism for cross-cutting. The combination of the two processes can produce glass wool boards of the same size.

[0004] Although the above-mentioned device can cut fiberglass wool boards longitudinally and transversely, all the wool boards cut by the transverse cutting mechanism are of uniform size. When the size required by the customer does not match the size, the transversely cut wool boards need to be cut again, which reduces production efficiency. Utility Model Content

[0005] In order to improve the production efficiency of fiberglass wool products, this utility model provides a fiberglass wool cutting device.

[0006] The fiberglass wool cutting device provided in this application adopts the following technical solution:

[0007] A fiberglass wool cutting device includes a conveyor belt, a hydraulic punch, and a cutting tool mounted on the hydraulic punch. The upper surface of the conveyor belt spans the worktable of the hydraulic punch, and the lower surface of the conveyor belt abuts against the upper surface of the worktable. The cutting tool is detachably mounted on the punch head of the hydraulic punch via an mounting assembly and is positioned directly opposite the upper surface of the worktable. The cutting tool is located above the conveyor belt, is adapted to the required shape of the product, and is used to cut the fiberglass wool.

[0008] By adopting the above technical solution, fiberglass wool is moved by a conveyor belt. When the fiberglass wool moves to the upper surface of the hydraulic punch press, the conveyor belt stops moving, and the hydraulic punch press starts. The punch drives the cutting blade to move down, and the cutting blade cuts the fiberglass wool. The cut shape matches the required shape of the product. After cutting, the cutting blade moves back, and the conveyor belt continues to transport the fiberglass wool. The operator only needs to unload the cut fiberglass wool at the rear end of the conveyor belt. When the required shape of the product changes, the installation assembly is opened, the original cutting blade is disassembled, and a new cutting blade that matches the required shape of the product is installed. Only the cutting blade needs to be replaced, and there is no need for multiple handling and cutting to obtain a product of a specific shape. Therefore, the production efficiency of fiberglass wool products is improved.

[0009] Optionally, the installation components include:

[0010] Mounting plate, which is fixed to the punch of the hydraulic punch press;

[0011] A connecting plate is disposed on the lower surface of the mounting plate, and the cutting tool is fixedly mounted on the connecting plate;

[0012] The mounting bolts pass through the mounting plate and the connecting plate in sequence. The mounting bolts are threaded with mounting nuts. After the connection is in place, the mounting nuts are pressed against the lower surface of the connecting plate.

[0013] By adopting the above technical solution, during installation, the connecting plate with the cutting blade is placed against the lower surface of the mounting plate, and then the mounting bolts are passed through the mounting plate and the connecting plate. The mounting nut is then rotated to tighten against the lower surface of the connecting plate. Disassembly can be performed by reversing the operation, thereby improving the convenience of installing, positioning, disassembling, and replacing the cutting blade, thus improving the cutting efficiency of fiberglass wool products and thereby improving the production efficiency of fiberglass wool products.

[0014] Optionally, the cutting tool includes a first blade and a second blade, and a cotton storage space is formed between the first blade and the second blade. A sponge pad is provided in the cotton storage space, and the thickness of the sponge pad is not less than the width of the first blade and the second blade.

[0015] By adopting the above technical solution, the punch moves downward, causing the first and second cutting edges to move downward as well. The sponge pad first presses against the fiberglass wool with the first and second cutting edges to position the fiberglass wool and reduce shaking during the cutting process. As the punch continues to move downward, the sponge pad is squeezed and deformed, and the first and second cutting edges cut the fiberglass wool. After cutting, the punch moves back, causing the first and second cutting edges to move back as well. During the return movement, the sponge pad squeezes the cut fiberglass wool to prevent the cut surface of the fiberglass wool from adhering to the cutting edges and moving upward. After the first and second cutting edges completely detach from the fiberglass wool, the sponge pad gradually recovers its deformation until it detaches from the fiberglass wool, thereby improving the cutting efficiency of the fiberglass wool.

[0016] Optionally, the cutting tool further includes a third blade and a fourth blade, wherein the first blade, the third blade, the second blade and the fourth blade are connected end to end to form the aforementioned cotton storage space.

[0017] By adopting the above technical solution, the structure of the sponge pad and the cotton storage space are adapted to each other, which facilitates the positioning of fiberglass cotton of different shapes, thereby improving the cutting efficiency of fiberglass cotton.

[0018] Optionally, the thickness of the sponge pad is 2-3 times the width of the first blade.

[0019] By adopting the above technical solution, the thickness of the sponge pad is optimized so that it can limit the fiberglass wool while reducing the impact on the operation of the cutting tool.

[0020] Optionally, the mounting plate has guide rods extending vertically upward at each of the four corners of its upper surface, and the hydraulic press has guide openings corresponding to the guide rods one by one. The guide rods are coaxial and slide through the corresponding guide openings.

[0021] By adopting the above technical solution, the cooperation between the guide rod and the guide port improves the stability of the mounting plate movement.

[0022] Optionally, it also includes a drive assembly for moving the conveyor belt. The drive assembly includes a drive roller, a transmission roller, and a drive motor. There are two drive rollers, which are respectively located at the front and rear ends of the conveyor belt. There are multiple transmission rollers, which are spaced apart between the two drive rollers. The conveyor belt is wound between the two drive rollers and supported by the multiple transmission rollers. The drive motor is connected to one of the drive rollers.

[0023] By adopting the above technical solution, the drive motor, drive roller and transmission roller work together to move the conveyor belt, thereby realizing the movement of the fiberglass wool during the cutting process.

[0024] Optionally, the front end of the conveyor belt is also provided with a pressure roller, which cooperates with the drive roller located at the front end to flatten the fiberglass cotton before cutting.

[0025] By adopting the above technical solution, before cutting, the front end of the fiberglass wool is extended onto the conveyor belt located between the drive roller and the pressure roller. The pressure roller, in conjunction with the drive roller and the conveyor belt, flattens the fiberglass wool before cutting. The flattened fiberglass wool is then moved to the hydraulic punch press by the conveyor belt for cutting, thereby improving the cutting effect and thus increasing the production efficiency of fiberglass wool products.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Fiberglass wool is moved by a conveyor belt. When the fiberglass wool reaches the upper surface of the hydraulic punch press, the conveyor belt stops moving, and the hydraulic punch press starts. The punch drives the cutting blade downward, and the cutting blade cuts the fiberglass wool. The cut shape matches the required shape of the product. After cutting, the cutting blade moves back, and the conveyor belt continues to transport the fiberglass wool. The operator only needs to unload the cut fiberglass wool at the rear end of the conveyor belt. When the required shape of the product changes, the installation assembly is opened, the original cutting blade is disassembled, and a new cutting blade that matches the required shape of the product is installed. Only the cutting blade needs to be replaced, and there is no need for multiple handling and cutting to obtain a product of a specific shape. Therefore, the production efficiency of fiberglass wool products is improved.

[0028] 2. The punch moves downward, causing the first and second cutting blades to move downward as well. The sponge pad first presses against the fiberglass wool with the first and second cutting blades to position the fiberglass wool and reduce shaking during the cutting process. As the punch continues to move downward, the sponge pad is squeezed and deformed, and the first and second cutting blades cut the fiberglass wool. After cutting, the punch moves back, causing the first and second cutting blades to move back as well. During the return movement, the sponge pad squeezes the cut fiberglass wool to prevent the cut surface of the fiberglass wool from adhering to the cutting blades and moving upward. After the first and second cutting blades are completely detached from the fiberglass wool, the sponge pad gradually recovers its deformation until it is detached from the fiberglass wool, thereby improving the cutting efficiency of the fiberglass wool.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a fiberglass wool cutting device.

[0038] Example 1

[0039] Reference Figure 1 and Figure 2 A fiberglass cotton cutting device includes a conveyor belt 1, a hydraulic punch 2, and a cutting tool 3 mounted on the hydraulic punch 2. For ease of explanation, this embodiment describes the fiberglass cotton cutting device mounted on a frame 4. The upper surface of the conveyor belt 1 spans across the worktable 21 of the hydraulic punch 2, and the lower surface of the conveyor belt 1 abuts against the upper surface of the worktable 21. The cutting tool 3 is detachably mounted on the punch 22 of the hydraulic punch 2 via a mounting assembly 5 and is positioned directly opposite the upper surface of the worktable 21. The cutting tool 3 is located above the conveyor belt 1 and is adapted to the required shape of the product for cutting the fiberglass cotton.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The fiberglass wool cutting device also includes a drive assembly 6 for moving the conveyor belt 1. The drive assembly 6 includes a drive roller 61, a transmission roller 62, and a drive motor 63. There are two drive rollers 61, which are rotatably mounted on the frame 4 and located at the front and rear ends of the conveyor belt 1, respectively. There are multiple transmission rollers 62, which are rotatably mounted on the frame 4 and spaced between the two drive rollers 61. The conveyor belt 1 is wound between the two drive rollers 61 and supported by the multiple transmission rollers 62. The drive motor 63 is mounted on the frame 4 and its output end is connected to one of the drive rollers 61.

[0041] In practical applications, the moving speed of the conveyor belt 1 can be calculated based on the diameter of the drive roller 61 and the motor speed. The controller can then be connected to set the automatic start and stop of the drive motor 63. For example, if the conveyor belt 1 needs to stop moving every 1.5m, the time required for it to move 1.5m can be calculated based on its moving speed. Combined with the motor speed, the running time of the motor when the conveyor belt 1 moves a specified distance can be obtained. The motor can then be set to stop after the specified time. When the conveyor belt 1 moves 1.5m forward, the drive motor 63 stops, the hydraulic punch 2 starts, and the cutting tool 3 moves downward for cutting. After cutting, the cutting tool 3 moves back, and the drive motor 63 starts again, allowing the conveyor belt 1 to continue moving forward 1.5m for the next cutting. This control can be adjusted according to actual use. This application does not impose any restrictions on the program control involved.

[0042] Reference Figure 1 and Figure 2 The front end of the conveyor belt 1 is also provided with a pressure roller 11. The pressure roller 11 is rotatably mounted on the frame 4 and is located above the drive roller 61 at the front end. The pressure roller 11 and the drive roller 61 at the front end are used to flatten the fiberglass cotton before cutting.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The hydraulic punch press 2 adopts conventional equipment in the existing technology (the structure of the hydraulic punch press 2 with model YL41-100t can be referenced). The punch 22 of the hydraulic punch press 2 moves telescopically in the vertical direction.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The mounting assembly 5 includes a mounting plate 51, a connecting plate 52, and mounting bolts 53. The mounting plate 51 is fixed on the punch 22 of the hydraulic punch press 2 and is parallel to the worktable 21 of the hydraulic punch press 2. The connecting plate 52 is disposed on the lower surface of the mounting plate 51, and the cutting tool 3 is fixed on the lower surface of the connecting plate 52.

[0045] Reference Figure 1 , Figure 4 and Figure 5 There are multiple mounting bolts 53, which are spaced apart on the mounting plate 51. The mounting bolts 53 pass vertically through the mounting plate 51 and the connecting plate 52 in sequence. The end of the mounting bolt 53 away from the end head is threaded with a mounting nut 531. After the connection is in place, the mounting nut 531 is pressed against the lower surface of the connecting plate 52. A nut washer is also provided between the mounting nut 531 and the connecting plate 52.

[0046] Reference Figure 1 , Figure 4 and Figure 5The cutting tool 3 is customized according to the required shape of the product. The required shape of the product is a plate with a width consistent with the width of the fiberglass cotton. It only needs to be cut along the length of the fiberglass cotton. The cutting tool 3 includes a first blade 31 and a second blade 32. The backs of the first blade 31 and the second blade 32 are fixed to the lower surface of the connecting plate 52 and the blades extend vertically downward. The dimensions of the first blade 31 and the second blade 32 are the same. A cotton storage space 311 is formed between the first blade 31 and the second blade 32. A sponge pad 7 is provided in the cotton storage space 311. The top of the sponge pad 7 can be fixed to the lower surface of the connecting plate 52 by means of adhesive or other means. The thickness of the sponge pad 7 is not less than the width of the first blade 31 and the second blade 32. Preferably, the thickness of the sponge pad 7 is 2-3 times the width of the first blade 31. The width of the first blade 31 mentioned here is the distance between the back of the blade and the blade.

[0047] Reference Figure 1 , Figure 2 and Figure 3 The mounting plate 51 has four vertically extending guide rods 511 on its upper surface. The hydraulic punch press 2 has guide openings 23 that correspond one-to-one with the guide rods 511. The guide rods 511 are coaxial and slide through the corresponding guide openings 23.

[0048] Example 2

[0049] Reference Figure 1 , Figure 2 and Figure 6 A fiberglass cotton cutting device, which differs from Embodiment 1, is provided in that the product required in this embodiment is a plate-shaped fiberglass cotton whose length and width are inconsistent with those of existing fiberglass cotton. The fiberglass cotton needs to be cut in both length and width directions. Therefore, the cutting tool 3 also includes a third blade 33 and a fourth blade 34. The first blade 31, the third blade 33, the second blade 32 and the fourth blade 34 are connected end to end to form the above-mentioned cotton storage space 311.

[0050] Example 3

[0051] A fiberglass cotton cutting device differs from Embodiment 1 in that the product required in this embodiment is circular, the cutting blade 3 is a one-piece blade, and the one-piece blade forms the required circle. At this time, the cotton storage space 311 is the space formed by the one-piece blade.

[0052] Example 4

[0053] A fiberglass cotton cutting device differs from Embodiment 1 in that the product required in this embodiment is plum blossom shaped, and the cutting blade 3 is formed by multiple arc-shaped blades connected end to end. At this time, the cotton storage space 311 is the space surrounded by multiple arc-shaped blades.

[0054] In addition, in other feasible embodiments, the blade can be customized to any shape according to the customer's needs, and the space inside the blade is the cotton storage space 311, which is used to install the sponge pad 7.

[0055] The working principle of this application embodiment:

[0056] Before cutting, the front end of the fiberglass cotton is extended onto the conveyor belt 1 located between the drive roller 61 and the pressure roller 11. The pressure roller 11 cooperates with the drive roller 61 and the conveyor belt 1 to flatten the fiberglass cotton before cutting. The flattened fiberglass cotton is moved to the hydraulic punch 2 via the conveyor belt 1. When the fiberglass cotton moves to the upper surface of the worktable 21 of the hydraulic punch 2, the conveyor belt 1 stops moving.

[0057] The hydraulic punch press 2 starts, and the punch 22 drives the cutting tool 3 to move downward. The sponge pad 7 first places the cutting tool 3 against the fiberglass wool to position the fiberglass wool and reduce shaking during the cutting process. The punch 22 continues to move downward, and the sponge pad 7 is squeezed and deformed. The cutting tool 3 cuts the fiberglass wool. After cutting, the punch 22 moves back, driving the cutting tool 3 to move back. During the return movement, the sponge pad 7 squeezes the cut fiberglass wool to prevent the cut surface of the fiberglass wool from adhering to the blade and moving upward. After the cutting tool 3 completely detaches from the fiberglass wool, the sponge pad 7 gradually restores its deformation until it detaches from the fiberglass wool, thereby improving the cutting efficiency of the fiberglass wool.

[0058] The cut shape matches the required shape of the product. After cutting, the cutting blade 3 moves back, and the conveyor belt 1 continues to transport the product. The worker only needs to discharge the cut fiberglass wool at the rear end of the conveyor belt 1. When the required shape of the product changes, the mounting nut 531 is turned to disengage the mounting screw and the mounting screw is removed. At this time, the connecting plate 52 and the cutting blade 3 are disassembled as a whole. Then, a new cutting blade 3 that matches the required shape of the product is installed. After installation, a new cut can be made. In this process, only the cutting blade 3 needs to be replaced. There is no need for multiple handling and cutting to obtain a product of a specific shape, thus improving the production efficiency of fiberglass wool products.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
