Description

Technical Field

[0001] The utility model relates to the technical field of film removal equipment, in particular to a dust collecting hood component and a film removal device. Background Art

[0002] Some glass processing plants require cutting the purchased coated glass sheets during the processing process. Before cutting, the coated glass needs to be de-coated. The main reasons for de-coating coated glass include preventing corrosion and oxidation of the coating layer and ensuring the airtightness of the insulating glass.

[0003] In the related art, coating removal on coated glass usually requires the use of a grinding wheel, which rotates at high speed to grind away the coating layer on the surface of the coated glass. However, the coating removal process generates a large amount of debris such as powder and particles, which need to be removed promptly.

[0004] Generally, a vacuum cleaner is required to remove dust during the film removal process. However, for conventional grinding wheels that cannot be rotated in the horizontal plane for adjustment, a dust hood can be used to cover the grinding wheel and insert the vacuum cleaner's suction hose into the hood. However, for grinding wheels that can be rotated in the horizontal plane for adjustment, installing a dust hood outside the grinding wheel and inserting the vacuum cleaner's suction hose into the hood for dust removal is less convenient. This is because the suction hose cannot be directly fixed to the hood. Otherwise, the hood will become entangled with the suction hose as the grinding wheel rotates in the horizontal plane, making installation inconvenient. In addition, when the grinding wheel rotates in the horizontal plane for adjustment, it is very likely to touch and cut the suction hose. Therefore, for grinding wheels that can be rotated in the horizontal plane for adjustment, it is difficult to achieve the goal of removing film and removing dust simultaneously.

[0036] Figure 1 and Figure 2The following figure shows the partial structure of a film removal device provided by one embodiment of the present invention. The device includes a dust collection hood assembly 100, a film removal assembly 200, a rotating shaft 400, and a vacuum cleaner (not shown). The film removal assembly 200 is used to remove film from the object to be removed; the rotating shaft 400 is used to drive the film removal assembly 200 to rotate, allowing it to rotate and change position, achieving multi-angle film removal. The dust collection hood assembly 100 is used to collect debris removed during film removal, making it easier for the vacuum cleaner to remove it. The object to be removed can be coated glass.

[0037] Combine Figure 3 and Figure 4 The dust collecting cover assembly 100 includes an upper dust collecting part 110 , a lower dust collecting part 120 and a cover body 130 .

[0038] The upper dust collecting part 110 is provided with a middle hole 111, and the upper dust collecting part 110 is also provided with a dust collecting chamber 112 arranged around the middle hole 111 and separated from the middle hole 111; the lower dust collecting part 120 is rotatably connected to the bottom of the upper dust collecting part 110, and the lower dust collecting part 120 is provided with a connecting channel 124, and the connecting channel 124 is configured to be connected with the dust collecting chamber 112 no matter where the lower dust collecting part 120 rotates relative to the upper dust collecting part 110; the cover body 130 is connected to the bottom of the lower dust collecting part 120, and the top of the cover body 130 is provided with a connecting port 131 connected to the connecting channel 124.

[0039] The middle hole 111 is used for setting the bearing 300, wherein the outer ring of the bearing 300 is tightly pressed against the hole wall of the middle hole 111, and in order to prevent the bearing 300 from falling out of the middle hole 111, a retaining ring can also be set in the middle hole 111 to clamp the bearing 300 and prevent the bearing 300 from moving along the axial direction of the bearing 300.

[0040] The dust collection pipe of the vacuum cleaner is connected to the upper dust collecting part 110 , and the internal channel of the dust collection pipe is connected to the dust collecting chamber 112 . When the vacuum cleaner is working, the debris in the dust collecting chamber 112 can be sucked away.

[0041] Specifically, a connecting pipe 140 is connected to the top of the upper dust collecting member 110 , an internal channel of the connecting pipe 140 is communicated with the dust collecting chamber 112 , and a dust collection pipe of the vacuum cleaner is connected to the connecting pipe.

[0042] It should be noted that the vacuum cleaner is generally arranged above the film removal assembly 200. By setting the connecting pipe 140 on the top of the upper dust collecting part 110, the dust suction pipe of the vacuum cleaner only needs to be connected to the connecting pipe 140, and no longer needs to extend to the bottom of the cover body 130 and into the cover body 130 to perform dust suction, which can reduce the length of the dust suction pipe.

[0043] Combine Figure 3 and Figure 4The rotating shaft 400 passes through the bearing 300 and is tightly abutted against the inner ring of the bearing 300. The bottom end of the rotating shaft 400 is connected to the lower dust collecting member 120. The rotating shaft 400 can be controlled to rotate, thereby driving the lower dust collecting member 120 to rotate relative to the upper dust collecting member 110. It should be noted that the rotating shaft 400 can rotate around the axis of the rotating shaft 400 under the drive of a motor or other driving mechanism.

[0044] It can be understood that the dust collecting chamber 112 is an annular structure, and the dust collecting chamber 112 surrounds the middle hole 111 and is coaxially arranged with the middle hole 111. When the rotating shaft 400 drives the lower dust collecting part 120 to rotate relative to the upper dust collecting part 110, the lower dust collecting part 120 also rotates with the axis of the middle hole 111 as the axis center. No matter where the lower dust collecting part 120 rotates relative to the upper dust collecting part 110, the connecting channel 124 on the lower dust collecting part 120 is connected to the dust collecting chamber 112.

[0045] Furthermore, the lower dust collecting piece 120 is further provided with a mounting hole 121 arranged opposite to the middle hole 111 , and the rotating shaft 400 is further passed through the mounting hole 121 and fixedly connected to the lower dust collecting piece 120 .

[0046] The connection method between the rotating shaft 400 and the lower dust collecting part 120 includes but is not limited to fixing with screws, buckles or adhesive.

[0047] The cover body 130 is connected to the bottom of the lower dust collecting part 120 and can rotate with the cover body 130, and the communication port 131 on the top of the cover body 130 is connected to the communication channel 124, so that the inner cavity 132 of the cover body 130 can be connected to the dust collecting chamber 112.

[0048] Specifically, the top of the cover body 130 is fixedly connected to the lower dust collecting part 120, and the communicating channel 124 runs through the upper and lower sides of the lower dust collecting part 120, wherein the top of the communicating channel 124 is connected to the dust collecting chamber 112, and the lower end of the communicating channel 124 is connected to the communicating port 131 at the top of the cover body 130, and the communicating port 131 is connected to the inner cavity 132 of the cover body 130, so that the inner cavity 132 of the cover body 130 can be connected to the dust collecting chamber 112.

[0049] Combine Figure 1 and Figure 3 The film removal assembly 200 is connected to the lower dust collecting member 120 and can also rotate with the lower dust collecting member 120. The film removal assembly 200 includes a film removal tool 210 and a rotary drive member 220 for driving the film removal tool 210 to rotate. The film removal tool 210 is located in the inner cavity 132 of the cover body 130. The rotary drive member 220 is used to drive the film removal tool 210 to rotate. The film removal tool 210 can remove film from the object to be removed during rotation. The film removal tool 210 can be a grinding wheel.

[0050] Specifically, a mounting bracket 230 is also connected to the bottom of the lower dust collecting member 120, and the mounting bracket 230 and the cover body 130 are arranged in a horizontal direction. The rotating driving member 220 is a motor, and the rotating driving member 220 is fixed on the mounting bracket 230. The driving shaft of the rotating driving member 220 is connected to the film removal tool 210, and the film removal tool 210 is located in the inner cavity 132 of the cover body 130. The rotating driving member 220 is used to drive the film removal tool 210 to rotate. The debris generated by the film removal tool 210 when removing the film from the film-to-be-removed part will be blocked by the cover body 130 to prevent the debris from splashing at will, and the debris blocked in the cover body 130 will enter the dust collecting chamber 112 under the suction action of the vacuum cleaner, and then be sucked into the vacuum cleaner.

[0051] The dust collecting hood assembly 100 of the present invention can be used in combination with a film removal assembly 200 that can be driven to rotate by a rotating shaft 400. When the film removal assembly 200 removes the film from the part to be removed, it prevents the scraped debris from splashing randomly and plays the role of collecting dust. With the help of a vacuum cleaner, the debris can be quickly cleaned up.

[0052] Combine Figure 3 and Figure 4 In some embodiments, the dust collecting chamber 112 extends through the lower sidewall of the upper dust collecting member 110. The lower dust collecting member 120 includes a cover portion 122 positioned below the dust collecting chamber 112. A communication channel 124 is provided on the cover portion 122 and extends through both the upper and lower sides of the cover portion 122. The upper end of the communication channel 124 communicates with the dust collecting chamber 112, while the lower end of the communication channel 124 communicates with the communication port 131. Thus, when the lower dust collecting member 120 is driven by the rotating shaft 400 and rotates relative to the upper dust collecting member 110, the upper end of the communication channel 124 always faces the open bottom of the dust collecting chamber 112, ensuring that the lower dust collecting member 120 remains connected to the dust collecting chamber 112 regardless of its rotation relative to the upper dust collecting member 110. Furthermore, the portion of the cover portion 122 not provided with the communication channel 124 serves to cover the bottom of the dust collecting chamber 112, preventing debris that has entered the dust collecting chamber 112 from escaping.

[0053] Furthermore, an annular groove 123 is formed on the upper side of the covering portion 122 , wherein the upper end of the connecting channel 124 passes through the bottom wall of the annular groove 123 , the bottom of the upper dust collecting part 110 is passed through the annular groove 123 , and the lower end of the dust collecting chamber 112 is placed in the annular groove 123 .

[0054] Among them, a sealing ring is provided between the outer wall of the upper dust collecting member 110 and the groove wall of the annular groove 123. In this way, the sealing effect between the upper dust collecting member 110 and the lower dust collecting member 120 can be ensured, thereby reducing the risk of debris in the dust collecting chamber 112 splashing out from the side.

[0055] It should be noted that the sealing ring is made of elastic material. Although the sealing ring is arranged between the outer wall of the upper dust collecting part 110 and the groove wall of the annular groove 123, it will not hinder the lower dust collecting part 120 from rotating relative to the upper dust collecting part 110.

[0056] Furthermore, a slot is provided on the outer side wall of the upper dust collecting member 110, and at least a portion of the seal is completely disposed in the slot.

[0057] In the film removal device of the present invention, the film removal assembly 200 is used to remove film from the object to be removed; the rotating shaft 400 is used to drive the film removal assembly 200 to rotate, thereby allowing the film removal assembly 200 to rotate and change position, achieving the purpose of multi-angle film removal; the dust collection hood assembly 100 is used to collect debris removed during film removal, making it easier for a vacuum cleaner to suck it away. The dust collection hood assembly 100 can be used in conjunction with the film removal assembly 200, which can be driven by the rotating shaft 400 to rotate. When the film removal assembly 200 is removing film from the object to be removed, it prevents scraped debris from scattering randomly, serves as a dust collection function, and can be quickly cleaned up with the help of a vacuum cleaner.
