Description

Technical Field

[0001] This utility model relates to the field of sandpaper production technology, and in particular to a dust-free ceramic dry sandpaper punching device that facilitates material feeding. Background Technology

[0002] The advantages of dust-free ceramic dry sandpaper mainly include the following aspects: 1) Anti-clogging and anti-static: Dust-free ceramic dry sandpaper uses synthetic resin as a binder to bond silicon carbide abrasive to latex and is covered with an anti-static coating. This gives it anti-clogging and anti-static properties, enabling it to maintain high efficiency during dry sanding. 2) High abrasion resistance: This sandpaper has excellent abrasion resistance and is suitable for long-term and high-intensity sanding operations. The abrasive and latex are firmly bonded and not easily detached, extending its service life. 3) Wide range of applications: Dust-free ceramic dry sandpaper is suitable for sanding various materials, including metals, wood, and plastics, and is particularly suitable for the rough sanding stages in the furniture and decoration industries. 4) High-efficiency grinding: Due to its large abrasive grain gaps, the dust generated during grinding easily falls off and does not clog the sandpaper surface, thereby improving grinding efficiency. 5) Low dust and anti-static: Strict dust removal and anti-static treatment is carried out during the production process, effectively controlling the amount of static electricity generated and preventing dust adsorption and damage to electronic components, making it particularly suitable for places with high cleanliness requirements.

[0003] Existing dust-free ceramic dry sandpaper punching devices have shortcomings in use. First, they cannot punch the chip removal holes simultaneously with punching the round sandpaper; second, they cannot achieve rapid material unloading. Therefore, their structure needs to be optimized and improved. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a dust-free ceramic dry sanding paper punching device that facilitates material feeding.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A dust-free ceramic dry sandpaper punching device for easy material feeding includes a pressure-bearing component and a punching component disposed above it.

[0007] The pressure-bearing assembly includes a pressure-bearing box, an annular groove on the upper side of the pressure-bearing box, an installation cavity inside the pressure-bearing box, a plurality of punching push rods evenly installed on the bottom surface of the installation cavity, a punch for forming chip removal holes on round sandpaper installed on the movable end of the punching push rod, and a lower clearance groove that mates with the punch on the top wall of the installation cavity.

[0008] The stamping assembly includes a base plate, a stamping push rod is mounted on the lower side of the base plate, a movable box is mounted on the movable end of the stamping push rod, a cutter is provided on the lower side of the movable box, a waste sheet collection cavity is provided inside the movable box, and a plurality of upper clearance grooves are opened on the bottom surface of the waste sheet collection cavity, the positions of the upper clearance grooves correspond one-to-one with the positions of the lower clearance grooves.

[0009] Furthermore, in the above-mentioned dust-free ceramic dry sandpaper punching device, the cutter is a notched annular cutter, the annular cutter and the annular groove cooperate with each other, and the round sandpaper is connected to the sandpaper strip after punching through the connection point formed by the notch.

[0010] Furthermore, in the aforementioned dust-free ceramic dry sandpaper punching device, the punch can enter the waste sheet collection chamber through the lower clearance groove and the upper clearance groove.

[0011] Furthermore, in the above-mentioned dust-free ceramic dry sanding paper punching device, an exhaust fan is installed on the upper side of the substrate, an outer tube is installed on the lower side of the substrate, an inner tube is installed on the upper side of the movable box, the inner tube is slidably restricted in the outer tube, and the suction end of the exhaust fan is connected to the waste sheet collection chamber through the outer tube and the inner tube.

[0012] Furthermore, in the aforementioned dust-free ceramic dry sanding paper punching device, the exhaust fan is equipped with a filter screen for intercepting the chip discharge hole punches.

[0013] Furthermore, in the aforementioned dust-free ceramic dry sanding paper punching device, the side end of the movable box is provided with an air vent that communicates with the outside.

[0014] The beneficial effects of this utility model are:

[0015] This utility model device is reasonably designed, mainly consisting of a pressure-bearing component and a stamping component. After the cutter of the stamping component and the annular groove of the pressure-bearing component are connected, they can stamp a round sandpaper with connection points on the sandpaper strip. The stamping push rod in the pressure-bearing component drives the punch to move upward, and the punch can stamp a chip removal hole on the round sandpaper.

Finally, the round sandpaper with chip removal holes can be pulled away from the punching machine by the sandpaper strip. Afterward, only the push rod and other mechanisms need to apply pressure to the round sandpaper to make the round sandpaper quickly separate from the sandpaper strip.
