Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum-plastic plate production, in particular to a trimming device for cutting aluminum-plastic plates. Background Art
[0002] The aluminum-plastic composite panel is made of multiple layers of materials. The upper and lower layers are high-purity aluminum alloy plates, the middle layer is a non-toxic low-density polyethylene (PE) core plate, and a layer of protective film is pasted on the front.
[0003] After the aluminum-plastic plate is cut, there are burrs on the metal edge and the edge of the plastic layer is not smooth. Therefore, the aluminum-plastic plate needs to be trimmed after cutting. When trimming, a grinding wheel is generally attached to the edge of the aluminum-plastic plate, and the grinding wheel uniformly grinds the edge of the aluminum-plastic plate. Since the upper and lower surfaces of the aluminum-plastic plate are aluminum metal plates and the middle layer is plastic, the materials are different. When the burrs of the aluminum plate splash, they will be rolled into the gap between the aluminum plate and the plastic layer by the grinding wheel. The burrs will be brought in and adhered to the outer wall of the plastic layer, making it difficult to grind the edge of the plastic layer flat at one time and the burrs of the aluminum-plastic plate are embedded in the outer wall of the plastic layer and difficult to remove.

[0017] like Figure 1-5 The trimming device for cutting aluminum-plastic panels shown in the figure comprises a base 1 having a trimming assembly installed on the side of the base 1, the trimming assembly comprising a sanding disc 1 5, a sanding disc 2 6 and a sanding wheel 8, a fixed plate 2 is fixedly installed on one side edge of the base 1, a notch is provided on the plate surface of the fixed plate 2, the sanding disc 1 5 is movably installed inside the notch, a connecting rod 12 is fixedly installed at the top center of the sanding disc 1 5, a sanding disc 2 6 is fixedly installed on the top of the connecting rod 12, a matching groove 13 is provided at the center of the sanding wheel 8, the sanding wheel 8 is sleeved and installed on the outside of the connecting rod 12 through the matching groove 13, and the sanding wheel 8 is installed between the sanding disc 1 5 and the sanding disc 2 6.
[0018] A rack 7 is fixedly installed on the inner wall of the fixed plate 2, a gear 14 is fixedly installed on the bottom of the sanding disc 1 5, and the gear 14 meshes with the rack 7. A limit plate 3 is fitted on the top of the sanding disc 2 6, and the end of the limit plate 3 is fixedly connected to the fixed plate 2. A slide groove is provided on the outer wall of the limit plate 3, and a slider is fixedly installed on the top of the sanding disc 2 6, and the slider is embedded in the slide groove. The shape of the connecting rod 12 is a regular column with a rounded rectangular end face, and the notch of the matching groove 13 is gourd-shaped. The notch shape of one side of the matching groove 13 is adapted to the outer wall of the connecting rod 12, and the other end is an arc-shaped notch, and the space area of the arc-shaped notch is larger than the notch area adapted to the connecting rod 12.
[0019] The motor 9 is installed at the bottom of the gear 14, and the gear 14 is driven by the motor 9. A movable plate 11 is fixedly installed on one side of the motor 9, and a guide plate 10 is fixedly installed on the bottom surface of the base 1. The movable plate 11 is an L-shaped bent plate, and the guide plate 10 is also an L-shaped bent plate. One side edge of the guide plate 10 is fixedly connected to the bottom surface of the base 1, and there is a gap between the bottom surface of the base 1. The bent end of the movable plate 11 is embedded in the gap between the guide plate 10 and the bottom surface of the base 1. The outer wall of the side of the motor 9 where the movable plate 11 is not installed is fixedly installed with a cylinder 4, and the output end of the cylinder 4 faces the grinding wheel 8. The output end of the cylinder 4 is fixedly installed with an arc-shaped magnetic plate, and the shape of the magnetic plate is adapted to the outer wall of the grinding wheel 8.
[0020] Embodiment: The aluminum-plastic plate is placed on the base 1, and the edge of one side of the aluminum-plastic plate to be polished is fitted with the outer wall of the trimming assembly composed of the grinding disc 1 5, the grinding disc 2 6 and the grinding wheel 8. In the initial state, the magnetic plate at the end of the cylinder 4 and the grinding wheel 8 made of iron metal material are mutually attracted, and the connecting rod 12 is embedded in the matching groove 13 and the end of the connecting rod 12 that is adapted in shape. During the first trimming, the cylinder 4 is started and the grinding wheel 8 is pulled in the direction of the cylinder 4, so that the grinding wheel 8 does not fit the outer wall of the aluminum-plastic plate. As the cylinder 4 is pulled, the connecting rod 12 enters the arc-shaped notch area of the matching groove 13, and the connecting rod 12 does not contact the inner wall of the matching groove 13 in this area. Then the motor 9 is started to drive the gear 14 to rotate at a constant speed. The gear 14 rotates and translates on the rack 7. Since the movable plate 11 is embedded in the guide plate 10, when the gear 14 rotates, it will drive the motor 9 and the cylinder 4 to translate along the rack 7. At this time, the grinding disc 1 5 and the grinding disc 2 6 rotate to grind the edges of the upper and lower aluminum plates of the aluminum-plastic plate, and the slider at the top of the grinding disc 2 6 slides in the slide groove of the limit plate 3. The limit plate 3 can help the grinding disc 2 6 not to deviate from the direction during trimming.
[0021] After the gear 14 moves from one end of the rack 7 to the other end, the edges of the upper and lower aluminum plates of the aluminum-plastic plate are trimmed, and the cylinder 4 drives the grinding wheel 8 to reset, and the notch on one side of the matching groove 13 fits with the outer wall of the connecting rod 12. Then the motor 9 drives the gear 14 to rotate, and the grinding wheel 8 is driven by the connecting rod 12 to rotate to grind the plastic layer in the middle of the aluminum-plastic plate. The magnetic plate fits the curvature of the grinding wheel 8, so when the grinding wheel 8 rotates, the magnetic plate will not cause interference.
[0022] The grinding disc 1 5 and the grinding disc 2 6 are first used to grind the edge of the aluminum plate, and a large number of burrs are removed after trimming, so a large number of sharp burrs will not fly out during the second grinding, so when the grinding wheel 8 is grinding the edge of the plastic plate, the burrs will not be brought into the edge of the plastic plate by the grinding wheel 8.
[0023] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
[0024] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. 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 utility model, which all belong to the protection scope of the utility model.
