Description

Technical Field

[0001] This utility model relates to the technical field of sandpaper cutting equipment, and in particular to a sandpaper cutting mechanism and a sandpaper cutting system. Background Technology

[0002] Sandpaper consists of a base layer and a sanding layer covering the base layer. During processing, cutting equipment is used to cut strips of sandpaper into different sizes before packaging and sale. In existing technology, the commonly used cutting equipment includes a tray for holding the sandpaper. The base layer of sandpaper contacts the tray, while the sanding layer is located above the tray but not in contact with it. A cutter, driven by a telescopic actuator (such as a telescopic cylinder), is positioned above the tray. When cutting is needed, the sandpaper is placed on the tray, and the cutting position is adjusted to be directly below the cutter. The telescopic actuator moves the cutter downwards to cut, and then the cutter returns to its initial position, starting the next round of cutting. However, in actual operation, cutting often causes some sand particles to fall off the sanding layer, requiring timely cleaning; otherwise, it will affect subsequent cutting, ultimately reducing overall efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sandpaper cutting mechanism that solves the problem of reduced overall efficiency caused by the need to clean up particles that fall during the cutting process.

[0004] According to an embodiment, a sandpaper cutting mechanism is provided, comprising a tray and a fixed plate relatively fixed above the tray. A telescopic column is vertically inserted through the fixed plate, and a pressure block located between the fixed plate and the tray is fixedly connected to the lower end of the telescopic column. A through frame is provided on the tray, and a cutter capable of partially passing through the through frame is also provided below the tray. A suction hood is also fixedly provided on the side of the tray, and the suction hood has an intake port facing the upper end of the through frame. This solution differs from the prior art by placing the cutter below the tray, so the particles generated during cutting will fall downwards through the through frame and will not continue to affect subsequent cutting. At the same time, a suction hood is provided on the side, and an external exhaust fan can be used to suck up the generated particles, which can better ensure that the particles do not affect subsequent operations. Therefore, it solves the problem of reduced overall efficiency caused by the need to clean up particles falling during the cutting process in the prior art.

[0005] Furthermore, the telescopic column is fitted with a spring located between the fixed plate and the pressure block.

[0006] Furthermore, a pair of pressure strips located on both sides of the through frame are fixedly connected to the bottom surface of the pressure block.

[0007] Furthermore, a recessed receiving groove is provided on the bottom surface of the pressing block. The receiving groove is located directly above the through frame and allows the upper end of the cutter to be inserted.

[0008] Furthermore, the molding strip is parallel to the frame and has a downward-curving arc surface.

[0009] Furthermore, the cutter includes a connecting section and a cutting section located above the connecting section. The cutting section has a triangular cross-section with the tip pointing upwards, and the receiving groove has a triangular cross-section for the upper end of the cutting section to be inserted into.

[0010] Furthermore, the fixed plate is provided with perforations, the telescopic column slides through the perforations, and the telescopic column is also fixedly connected to a limiting ring located above the fixed plate. The limiting ring can abut against or separate from the fixed plate.

[0011] According to an embodiment, a sandpaper cutting system is also provided, which includes the sandpaper cutting mechanism described above.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By placing the cutter below the tray and installing a through frame on the tray, the particles generated during cutting will fall downwards through the through frame and will not continue to affect subsequent cutting. At the same time, a suction hood is installed on the side, and an external exhaust fan can be used to suck up the generated particles, which can better ensure that the particles will not affect subsequent operations. Therefore, the problem of reduced overall efficiency caused by the need to clean up the particles generated during cutting in the existing technology is solved. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-3As shown, this embodiment provides a sandpaper cutting system, which includes a sandpaper cutting mechanism. Similar to existing technologies, the cutting mechanism includes a tray 1. However, unlike existing technologies, this solution places the cutter 2 at the bottom. Specifically, a through frame 3 is provided on the tray 1, and the cutter 2 is located below the tray 1, with the through frame 3 allowing the cutter 2 to partially pass through. A fixing plate 4 is fixedly positioned above the tray 1, with a through hole through which a telescopic column 5 is inserted. A pressure block 6 is fixedly connected to the lower end of the telescopic column 5, and a limiting ring 7 is fixedly connected to the telescopic column 5, capable of abutting or separating from the surface of the fixing plate 4. During cutting, sandpaper 8 is placed on the tray 1, and the cutting position is adjusted to be directly above the through frame 3. The telescopic column 5 is lowered so that the pressure block 6 presses against the sandpaper 8. Then, the cutter 2 moves upward through the through frame 3 to achieve cutting (similar to existing technologies, the cutter 2 is driven by a telescopic actuator). 5. Lift the pressure block upwards to release the downward pressure, replace the sandpaper 8 with the sandpaper 8 for the next round of cutting, and the next round of cutting can be carried out. If particles are generated during the process, they will pass through the frame 3 and fall below the tray 1, without affecting the normal progress of subsequent cutting. Therefore, the problem of particles falling during cutting and needing to be cleaned up, which leads to a decrease in overall efficiency, is solved in the prior art. Furthermore, this solution also has a suction hood 9 fixed on the side of the tray 1, and the suction hood 9 has an intake port 10 facing the upper end of the frame 3. The suction hood 9 is connected to a separate exhaust fan through a connecting pipe 11, which can provide negative pressure so that some particles are sucked into the suction hood 9 and leave the tray 1, which better ensures that particles will not affect the normal progress of subsequent cutting. In particular, a pair of suction hoods 9 can be set on both sides of the tray 1. A dust removal device can be connected behind the exhaust fan to collect particles. A receiving box or other container can also be set below the frame 3 to collect particles.

[0016] like Figure 1-3As shown, in a further embodiment, a spring 12 is arranged around the telescopic column 5 between the pressure block 6 and the fixed plate 4. The telescopic column 5 has an end located above the limiting ring 7, so that the operator can move the pressure block 6 upwards. This provides sufficient space between the pressure block 6 and the support plate 1 for the sandpaper 8 to be fed in and the cutting position adjusted. Furthermore, a pair of pressure strips 13 are fixedly connected to the bottom surface of the pressure block 6 on both sides of the through frame 3. These two pressure strips 13 are arranged parallel to the through frame 3. When the pressure block 6 is in the lowest position, the limiting ring 7 abuts against the fixed plate 4. Two pressure strips 13 are pressed on the support plate 1. After the telescopic column 5 is placed upward, the sandpaper 8 is placed on it. The two pressure strips 13 can press on the sandpaper 8, so that the pressure block 6 does not press on the sandpaper 8 completely during the cutting process, leaving space for the falling particles to be drawn into the suction hood 9. In a more detailed solution, the pressure strips 13 are set with a downward curved arc surface, so that they make arc contact with the sandpaper 8, avoiding excessive contact surface that would cause the particles on the sandpaper 8 to fall accidentally. The spring 12 also provides an upward pulling force so that the downward pressure applied by the pressure strips 13 is not too great, so as to avoid the particles falling accidentally.

[0017] like Figure 1-3 As shown, in a further embodiment, the cutter 2 includes a connecting section 14 connected to the telescopic actuator and a cutting section 15 located above the connecting section 14. The cross-section of the cutting section 15 can be a triangular structure with the tip pointing upwards, that is, the tip of the cutting section 15 is the cutting edge of the cutter 2. After contacting the sandpaper 8, it continues to cut upwards. More specifically, a receiving groove 16 is also recessed on the bottom surface of the pressure block 6. The receiving groove 16 is located directly above the through frame 3 and can allow the upper end of the cutter 2 to abut. That is, the receiving groove 16 can also be a triangular structure with a cross-section for the upper end of the cutting section 15 to abut.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
