Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a glass edging apparatus. Background Technology

[0002] When glass is first produced, it is often in large pieces. It is then cut into predetermined sizes and shapes according to actual needs. The edges of the cut glass are extremely sharp and can easily cut the skin. Furthermore, the cut edges of glass usually have many micro-cracks, which are weak points in the glass and can easily cause the entire piece of glass to break under external force. Therefore, edge grinding after glass cutting is an essential process.

[0003] Currently, there are specialized equipment for glass cutting and edging, and these professional glass edging machines offer excellent edging results. The problem lies in the fact that the various pieces of equipment in glass processing are generally independent. After glass is processed in one step, it needs to be transferred to another piece of equipment for the next step. This process is particularly troublesome when transferring glass from the cutting equipment to the edging equipment. This is because freshly cut glass has sharp edges that can easily injure workers, and the glass is also more fragile at this stage, requiring extra caution from workers. Therefore, this independent operation of each processing piece of equipment is not only inefficient but also poses higher safety risks.

[0004] Integrating glass cutting and edging equipment into a single conveyor system presents a potential hazard: both cutting and edging generate a significant amount of glass shards and dust. These shards are highly hard and tend to fly everywhere under stress during the process. Therefore, if they enter other equipment or machines, they can easily cause unnecessary scratches, especially in conveyor lines with numerous rotating parts, which are more susceptible to damage from glass shards. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a glass edging device to solve the technical problem in the prior art that glass shavings generated during the glass edging process are easily splashed into other machines, thereby causing wear.

[0006] To achieve the above objectives, the present invention provides a glass edging device, comprising a conveyor line consisting of two side plates and conveyor wheels, wherein a plurality of conveyor wheels are provided and rotatably connected between the two side plates, and the glass edging device further comprises:

[0007] The upper connecting plate and the lower connecting plate are fixedly connected between the two side plates and together form a negative pressure cavity for glass edge grinding. The upper connecting plate and the lower connecting plate are fixedly connected with sealing strips in the front and rear openings. There is an inlet and outlet gap with a width consistent with the glass thickness between the two sealing strips on the same side.

[0008] A grinding wheel is rotatably connected to the lower end of the upper connecting plate, and a grinding motor for driving the grinding wheel to rotate is fixedly connected to the upper connecting plate;

[0009] The nozzle is fixedly connected to the side plate and connected to an external water source through a water supply pipe;

[0010] The suction tube has one end fixedly connected to the lower connecting plate and connected to the negative pressure chamber, and the other end connected to the external water pump.

[0011] Furthermore, the side plate is equipped with a power component for driving the conveyor wheel to rotate. The power component is a servo motor, and the power component is connected to the shaft of the conveyor wheel through multiple transmission belts.

[0012] Furthermore, two sets of grinding wheels and edge-grinding motors are symmetrically arranged to simultaneously grind both sides of the glass. Two sets of nozzles are also symmetrically arranged, with the grinding wheels and nozzles in the same set being staggered.

[0013] Furthermore, the upper end of the sealing strip on the lower connecting plate is flush with the upper end of the conveyor wheel, and the sealing strip is composed of an elastic rubber strip and a copper sheet wrapped around the outside of the rubber strip.

[0014] Furthermore, positioning blocks are slidably connected in the front and rear openings of the upper and lower connecting plates. The positioning blocks are located on both sides of the sealing strip, and telescopic columns are fixedly connected to the positioning blocks. The inner end of the telescopic column is located in the cavity inside the fixed seat, and the fixed seat is fixedly connected to the side plate.

[0015] Furthermore, a piston plate is fixedly connected to the inner end of the telescopic column. The piston plate is slidably connected in the cavity inside the fixed seat, and the cavity inside the fixed seat is also connected to an external high-pressure air source through a vent connector.

[0016] Furthermore, a fixing plate is fixedly connected to the inner side of the fixing base, and the fixing plate is also fixedly connected to the upper connecting plate and the lower connecting plate to block the gap between the fixing base and the positioning block. The positioning block is slidably connected to the fixing plate.

[0017] Furthermore, a sealing plate is provided outside the front and rear openings of the upper and lower connecting plates. A cylinder is also fixedly connected to the upper connecting plate. The cross-section of the sealing plate is inverted L-shaped. The vertical part of the sealing plate is slidably connected to the upper and lower connecting plates, and the horizontal part of the sealing plate is connected to the output shaft of the cylinder.

[0018] Furthermore, two rotating rods are rotatably connected to the side plate. The two rotating rods are located on the front and rear sides of the upper connecting plate, respectively, and the distance between the two rotating rods is less than the length of the glass. A power pressure roller is fixedly connected to the rotating rod. The power pressure roller presses on the glass and is in rolling connection with it. The side plate is also provided with a pressure roller motor for driving the rotating rod to rotate.

[0019] Furthermore, each rotating rod has multiple power pressure rollers arranged at equal intervals, and the outer circumference of each power pressure roller is provided with a rubber sleeve, and the outer circumference of the conveying wheel is also provided with a rubber ring.

[0020] The beneficial effects of the present invention are as follows: 1. An edge grinding device is integrated into the original glass conveying line. An upper connecting plate and a lower connecting plate are set up to form a negative pressure chamber for edge grinding in conjunction with the original side plate. The negative pressure chamber is relatively closed. In addition, air is continuously drawn in through the suction pipe, so that a relative negative pressure is formed in the negative pressure chamber, thus effectively preventing glass fragments from flying around.

[0021] 2. In addition to the grinding wheel for edge grinding, the negative pressure chamber is also equipped with nozzles to rinse the grinding wheel and the side of the glass. This serves two purposes: firstly, it cools the glass, and secondly, the water flow carries the glass fragments away through the suction pipe, preventing the glass fragments from entering other machines.

[0022] 3. Install sealing strips to cooperate with the glass and block the openings on the front and rear sides of the upper and lower connecting plates, keeping the negative pressure chamber relatively sealed. Additionally, install sealing plates on both sides of the upper connecting plate; when the glass leaves the opening, the sealing plates can be activated by a cylinder to block the corresponding opening.

[0023] 4. Additionally, positioning blocks are set to press down on both sides of the glass. This serves two purposes: firstly, to work with the sealing strip to block the opening, and secondly, to finely adjust the position of the glass, ensuring that both sides of the glass are subjected to balanced force with the grinding wheels on both sides.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0036] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] The first aspect of the invention, as Figures 1 to 6As shown, in actual production, transferring glass from the cutting equipment to the edging equipment is particularly troublesome because the edges of freshly cut glass are sharp and can easily injure workers. Furthermore, the glass is more fragile at this stage, requiring extra caution from workers. Therefore, the glass edging device designed in this invention integrates the glass cutting and edging devices with a conveyor line, eliminating the need for manual transfer.

[0038] The conveyor line consists of two side plates 101 and a conveyor wheel 104. Several conveyor wheels 104 are provided and rotatably connected between the two side plates 101. The side plates 101 are provided with a power component 102 for driving the conveyor wheel 104 to rotate. The power component 102 is a servo motor, and the power component 102 is connected to the shaft of the conveyor wheel 104 through multiple transmission belts 103.

[0039] The key point is that an upper connecting plate 105 and a lower connecting plate 106 are also provided between the two side plates 101. The upper connecting plate 105 and the lower connecting plate 106 are fixedly connected to the side plates 101. The two side plates 101, the upper connecting plate 105, and the lower connecting plate 106 together form a relatively enclosed space. This relatively enclosed space is used for the edge grinding process of the glass 01. In addition, a suction pipe 109 is fixedly connected to the lower end face of the lower connecting plate 106. The suction pipe 109 is connected to this edge grinding space through the interface 108. The suction pipe 109 continuously pumps water and air into this edge grinding space, making this relatively enclosed space a negative pressure chamber 107.

[0040] A grinding wheel 110 is installed in the negative pressure chamber 107. The grinding wheel 110 is rotatably connected to the lower end of the upper connecting plate 105, and a grinding motor 111 for driving the grinding wheel 110 to rotate is fixedly connected to the upper connecting plate 105. Additionally, a nozzle 112 is fixedly connected to the side plate 101, and the nozzle 112 is connected to an external water source through a water supply pipe 113. A booster pump is also installed on the water supply pipe 113, giving the water jet from the nozzle 112 a certain initial velocity, thus achieving a flushing effect.

[0041] Preferably, two sets of grinding wheels 110 and edge-grinding motors 111 are symmetrically arranged to simultaneously grind both sides of the glass 01, and two sets of nozzles 112 are also symmetrically arranged. Each set of grinding wheels 110 and nozzles 112 has multiple sets, and the grinding wheels 110 and nozzles 112 in the same set are staggered.

[0042] Since the negative pressure chamber 107, formed by the upper connecting plate 105 and the lower connecting plate 106 in conjunction with the original side plate 101, is relatively closed, and air is continuously drawn in through the suction pipe 109, a relative negative pressure is formed in the negative pressure chamber 107, thus effectively preventing glass shards from flying around. Moreover, the nozzle 112 washes the sides of the grinding wheel 110 and the glass 01, which not only cools them down but also allows the water flow to carry the glass shards away through the suction pipe 109, preventing them from entering other machines.

[0043] The second aspect of the invention, as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, since the front and rear sides of the upper connecting plate 105 and the lower connecting plate 106 need to have openings so that the glass 01 can smoothly enter the negative pressure chamber 107, it makes it difficult to maintain the negative pressure environment in the negative pressure chamber 107, and some glass fragments may also jump out from this opening.

[0044] Therefore, in this embodiment, sealing strips 114 are fixedly connected to the front and rear openings of the upper connecting plate 105 and the lower connecting plate 106. A slit 115 with a width equal to the thickness of the glass 01 is provided between the two sealing strips 114 on the same side. The upper end of the sealing strip 114 on the lower connecting plate 106 is flush with the upper end of the conveyor wheel 104. The sealing strip 114 consists of an elastic rubber strip 121 and a copper sheet 122 wrapped around the rubber strip 121. Therefore, the sealing strip 114 has a certain deformation and its upper edge is arc-shaped, allowing the glass 01 to pass smoothly through the slit 115 between the two sealing strips 114, while simultaneously wrapping it with a copper sheet 122 to prevent the glass 01 from scratching the rubber strip 121.

[0045] In addition, positioning blocks 116 are slidably connected in the front and rear openings of the upper connecting plate 105 and the lower connecting plate 106. The positioning blocks 116 are located on both sides of the sealing strip 114, and telescopic columns 118 are fixedly connected to the positioning blocks 116. The inner end of the telescopic column 118 is located in the cavity in the fixed seat 117, and the fixed seat 117 is fixedly connected to the side plate 101.

[0046] A piston plate is fixedly connected to the inner end of the telescopic column 118. This piston plate is slidably connected in the cavity inside the fixed seat 117, and the cavity inside the fixed seat 117 is also connected to an external high-pressure air source through a vent connector 119. A corresponding air pipe is directly connected to the external high-pressure air source through the vent connector 119. An electric valve, preferably a multi-port valve, is installed in this air pipe to facilitate control of the air pressure in the cavity inside the fixed seat 117.

[0047] Preferably, a fixing plate 120 is fixedly connected to the inner side of the fixing base 117. The fixing plate 120 is also fixedly connected to the upper connecting plate 105 and the lower connecting plate 106 to block the gap between the fixing base 117 and the positioning block 116. The positioning block 116 is slidably connected to the fixing plate 120.

[0048] Therefore, before glass 01 enters the inlet / outlet gap 115, the cavity inside the fixing seat 117 is under negative pressure. At this time, the positioning block 116 retracts, facilitating the entry of glass 01 into the inlet / outlet gap 115. After glass 01 enters the inlet / outlet gap 115, the electric valve actuates, allowing high-pressure gas to enter the cavity inside the fixing seat 117, causing the telescopic column 118 to extend with the positioning block 116 to clamp glass 01. At this time, the sealing strip 114 cooperates with glass 01 to block the openings on the front and rear sides of the upper connecting plate 105 and the lower connecting plate 106, while the positioning block 116 presses down on both sides of glass 01. This serves two purposes: firstly, it cooperates with the sealing strip 114 to block the openings, and secondly, it allows for fine adjustment of the position of glass 01, ensuring that both sides of glass 01 are evenly stressed by the grinding wheels 110 on both sides.

[0049] When the glass 01 is not entering or leaving the inlet / outlet seam 115, in order to ensure that the negative pressure chamber 107 remains relatively sealed, a sealing plate 124 is provided outside the front and rear openings of the upper connecting plate 105 and the lower connecting plate 106. A cylinder 123 is also fixedly connected to the upper connecting plate 105. The cross-section of the sealing plate 124 is inverted L-shaped. The vertical part of the sealing plate 124 is slidably connected to the upper connecting plate 105 and the lower connecting plate 106, and the horizontal part of the sealing plate 124 is connected to the output shaft of the cylinder 123.

[0050] Therefore, when the glass 01 is about to pass through the inlet / outlet 115, the cylinder 123 drives the sealing plate 124 to move upward and open the inlet / outlet 115. After the glass 01 leaves the inlet / outlet 115, the cylinder 123 drives the sealing plate 124 to move downward and block the inlet / outlet 115, so that the negative pressure chamber 107 remains in a relatively sealed state.

[0051] Because the glass 01 is driven by the friction generated by its own weight pressing against the conveyor wheel 104 when the conveyor wheel 104 is conveying it, the friction is relatively small. When the glass 01 encounters significant resistance, it will slip against the conveyor wheel 104. To address this, the present invention adds two rotating rods 126, each with multiple power pressure rollers 125 arranged at equal intervals. The power pressure rollers 125 press against the glass 01 and are in rolling connection with it. The two rotating rods 126 are located on the front and rear sides of the upper connecting plate 105, respectively, and the distance between the two rotating rods 126 is less than the length of the glass 01. In addition, the side plate 101 is also equipped with a pressure roller motor 127 for driving the rotating rods 126 to rotate.

[0052] Preferably, the power pressure roller 125 is provided with a rubber sleeve 128 on its outer periphery, and the conveyor roller 104 is also provided with a rubber ring to improve friction.

[0053] In summary, this invention integrates a grinding device into the existing glass conveyor line. An upper connecting plate 105 and a lower connecting plate 106, together with the existing side plate 101, form a negative pressure chamber 107 for grinding. The negative pressure chamber 107 is relatively enclosed, and air is continuously drawn in through the suction pipe 109, creating a relative negative pressure within the chamber, thus effectively preventing glass fragments from flying around. In addition to the grinding wheel 110 for grinding, the negative pressure chamber 107 also includes nozzles 112 that flush the grinding wheel 110 and the sides of the glass 01. This serves two purposes: firstly, it cools the glass, and secondly, the water flow carries the glass fragments away through the suction pipe 109, preventing them from entering other machines.

[0054] A sealing strip 114 is provided to cooperate with the glass 01 to block the openings on the front and rear sides of the upper connecting plate 105 and the lower connecting plate 106, so that the negative pressure chamber 107 remains relatively sealed. Additionally, sealing plates 124 are provided on both sides of the upper connecting plate 105. When the glass 01 leaves the opening, the sealing plates 124 can be driven by the cylinder 123 to block the corresponding opening. Furthermore, positioning blocks 116 are provided to press against both sides of the glass 01, firstly to cooperate with the sealing strip 114 to block the opening, and secondly to fine-tune the position of the glass 01, ensuring that both sides of the glass 01 are evenly stressed by the grinding wheels 110 on both sides.
