Description
Technical Field
[0001] This utility model belongs to the technical field of glass processing machinery, specifically relating to a feeding mechanism for a glass edging machine. Background Technology
[0002] After glass is cut, its outer edge will form relatively sharp edges. In order to avoid being cut by the edges when handling the glass, the outer edge of the cut glass needs to be ground. Glass edging machine is a processing equipment for grinding and polishing the edges of glass. It is commonly used in the glass deep processing industry. In order to ensure the quality of glass edging and extend the service life of edging tools, the glass edging machine needs to use coolant for cooling, lubrication and surface rinsing when grinding glass.
[0003] The problem is that during the operation of a conventional glass edging machine, the coolant gradually seeps into the space between the timing belt and the timing pulley as the timing belt rotates, reducing the coefficient of friction between them. This causes the timing belt to slip and wear more intensely, affecting the feeding accuracy and stability of the glass, reducing the quality and production efficiency of the glass edging. Furthermore, the coolant is corrosive, and when it comes into contact with the timing pulley, it can cause it to rust or even be damaged, reducing the service life of the glass edging machine.
[0004] Therefore, further improvements are needed. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0031] See Figure 1-8 The feeding mechanism of this glass edging machine includes a frame 1, an edging main unit 2, and a feeding mechanism 3. The feeding mechanism 3 includes a conveying structure 31 and a pressing structure 32. The conveying structure 31 is fixed to the edging main unit 2 by a fastening structure. When the feeding mechanism 3 is working, the conveying structure 31 contacts the lower surface of the glass and pushes the glass to move, feeding the glass in the processing direction. The pressing structure 32 is movably installed on the edging main unit 2 by a height adjustment structure and is located above the conveying structure 31, moving back and forth along the height direction of the edging main unit 2. When the feeding mechanism 3 is working, the pressing structure 32 contacts the upper surface of the glass and presses the glass onto the conveying structure 31, preventing displacement of the glass during feeding. Specifically, in this embodiment, the conveying structure 31 includes a conveying bracket 311 and a conveying synchronous wheel 312. The conveying bracket 311 is fixed to the edging main unit 2 by fasteners, and the conveying synchronous wheel 312... Two wheels 312 are rotatably mounted on the left and right ends of the conveying bracket 311. The feeding mechanism 3 includes a feeding synchronous belt 310, which is wrapped around the outer edge of the conveying bracket 311 and the conveying synchronous wheels 312 and meshes with the two conveying synchronous wheels 312 respectively, and contacts the lower surface of the glass. The feeding synchronous belt 310 includes a synchronous belt body 3101 and a waterproof protrusion 3102. The waterproof protrusion 3102 is respectively disposed on the front and rear sides of the synchronous belt body 3101. When the feeding mechanism 3 is working, the waterproof protrusion 3102 blocks the coolant outside the feeding synchronous belt 310, preventing the coolant from entering the synchronous belt body 3101 and contacting the conveying synchronous wheels 312, reducing corrosion such as rusting of the conveying synchronous wheels 312, ensuring the service life of the feeding mechanism 3, and to a certain extent improving the service life of the glass edging machine.
[0032] In addition, by adopting the above technical solution for the feed timing belt 310, coolant is prevented from seeping between the feed timing belt 310 and the conveying timing pulley 312, ensuring the coefficient of friction between the feed timing belt 310 and the conveying timing pulley 312, preventing the feed timing belt 310 from slipping, reducing the wear of the feed timing belt 310, ensuring the feeding accuracy and stability of the glass, and improving the quality and production efficiency of glass edging.
[0033] Furthermore, in this embodiment, the waterproof protrusion 3102 extends outward from the side of the synchronous belt body 3101. Specifically, the waterproof protrusion 3102 extends forward from the front side of the synchronous belt and backward from the rear side of the synchronous belt body 3101. This ensures effective waterproofing while improving the structural strength of the feed synchronous belt 310. The radial dimension of the outer peripheral wall of the waterproof protrusion 3102 is comparable to the radial dimension of the outer peripheral wall of the synchronous belt body 3101, while the radial dimension of the inner peripheral wall of the waterproof protrusion 3102 is smaller than that of the synchronous belt body 3101. Specifically, the radial dimension of the inner peripheral wall of the belt body 3101 enables the feed timing belt 310 to have a waterproof function without affecting the cooperation between the feed timing belt 310 and other components. The waterproof protrusion 3102 is integrally formed with the timing belt body 3101. Specifically, the integral forming structure can ensure the structural strength of the feed timing belt 310 and prevent coolant from passing through the gap between the timing belt body 3101 and the waterproof protrusion 3102, thereby improving the waterproof performance of the feed timing belt 310. This is understandable to those skilled in the art.
[0034] Furthermore, the distance between the inner peripheral wall of the waterproof protrusion 3102 and the inner peripheral wall of the synchronous belt body 3101 is B. Specifically, in this embodiment, B is preferably 3mm. Through the above technical solution, while ensuring that the feed synchronous belt 310 has a waterproof effect, it is also possible to ensure that the feed synchronous belt 310 can be normally installed on the conveying synchronous pulley 312, and to ensure the transmission between the feed synchronous belt 310 and the conveying synchronous pulley 312. This is something that those skilled in the art can understand.
[0035] Furthermore, the feed timing belt 310 also includes teeth 3103. Specifically, in this embodiment, the number of teeth 3103 is preferably 254, evenly distributed on the inner peripheral wall of the timing belt body 3101 and located between the two waterproof protrusions 3102. The horizontal projection shape of the teeth 3103 is preferably trapezoidal, or the horizontal projection shape of the teeth 3103 can also be arc-shaped or triangular, etc., increasing the flexibility and adaptability of the design of the teeth 3103. When the feed timing belt 310 is installed on the conveying timing pulley 312, the teeth 3103 contact the outer peripheral wall of the conveying timing pulley 312, which can improve the friction coefficient between the feed timing belt 310 and the conveying timing pulley 312, or the conveying timing belt 310 can be more flexible and adaptable. The outer peripheral wall of the step wheel 312 is provided with a tooth groove corresponding to the tooth 3103. When the feed synchronous belt 310 is installed on the conveying synchronous wheel 312, the tooth 3103 extends into the tooth groove, which can improve the transmission effect between the feed synchronous belt 310 and the conveying synchronous wheel 312, ensure reliable transmission between the feed synchronous belt 310 and the conveying synchronous wheel 312, optimize the transmission performance between the feed synchronous belt 310 and the conveying synchronous wheel 312, and further improve the accuracy and stability of glass feeding. The tooth 3103 is integrally formed with the synchronous belt body 3101, ensuring the structural strength of the tooth 3103 and reducing the occurrence of accidental dislodgement of the tooth 3103 during operation, which can be understood by those skilled in the art.
[0036] Furthermore, in this embodiment, the feed timing belt 310 is preferably made of rubber material, or the feed timing belt 310 can also be made of polyurethane material. Through the above technical solutions, rubber material or polyurethane material has good wear resistance, water resistance and flexibility, which is suitable for the working environment of the glass edging machine and ensures the glass conveying work of the feed mechanism 3. Those skilled in the art can understand this.
[0037] Furthermore, in this embodiment, the conveying structure 31 also includes a baffle plate 313 and a conveying drive structure. Specifically, the baffle plate 313 is disposed on the front side of the conveying bracket 311. The baffle plate 313 can further reduce the amount of coolant entering the feed timing belt 310, further enhancing the waterproof effect of the conveying structure 31. The conveying drive structure includes a conveying motor 314, a first conveying reduction gearbox 315, a second conveying reduction gearbox 316, and a conveying drive shaft 317. The first conveying reduction gearbox 315 is fixedly mounted on the edge grinding host 2. The first conveying reduction gearbox 315 and the second conveying reduction gearbox 316 are connected... The conveyor motor 314 is preferably a servo motor and is fixed on the top surface of the second conveyor reduction gearbox 316. Its output shaft is connected to the input end of the second conveyor reduction gearbox 316. The conveyor drive shaft 317 is located on the front side of the first conveyor reduction gearbox 315. One end of its shaft is connected to the output end of the first conveyor reduction gearbox 315, and the other end is connected to one of the conveyor synchronous pulleys 312. This ensures the stable rotation of the conveyor synchronous pulley 312, thereby driving the feed synchronous belt 310 to convey the glass and improving the stability of the glass conveying. This is something that those skilled in the art can understand.
[0038] Furthermore, the clamping structure 32 includes a clamping bracket 320, a clamping synchronous pulley 321, a clamping synchronous belt 322, and a belt pressing component 323. Specifically, in this embodiment, the clamping bracket 320 is vertically adjustable and mounted on the edge grinding host 2. Preferably, there are two clamping synchronous pulleys 321, which are rotatably mounted on the left and right ends of the clamping bracket 320, respectively. The belt pressing component 323 is movably mounted on the bottom surface of the clamping bracket 320. A return spring is provided between the belt pressing component 323 and the clamping bracket 320, causing the clamping structure 32 to contact the glass. During glass grinding, the pressure belt component 323 provides a certain buffering effect between itself and the glass to prevent collisions that could damage the glass. The pressing timing belt 322 is wrapped around the outer edge of the pressing bracket 320, the pressing timing wheel 321, and the pressure belt component 323, and is engaged with the two pressing timing wheels 321 respectively. When the feeding mechanism 3 is working, the pressing timing belt 322 contacts the upper surface of the glass and applies appropriate pressure to the glass, ensuring that the glass is pressed tightly against the feeding timing belt 310. This ensures the stability and accuracy of the glass feeding and improves the quality of the glass edge grinding, which is understandable to those skilled in the art.
[0039] Furthermore, the height adjustment structure includes an outer adjusting cylinder 324, an inner adjusting cylinder 325, an adjusting motor 326, and an adjusting transfer case 327. Specifically, in this embodiment, the outer adjusting cylinder 324 is mounted on the rear side of the clamping bracket 320 via fastening components, the inner adjusting cylinder 325 is mounted on the grinding machine 2 via fastening components, the adjusting transfer case 327 is mounted on the top surface of the outer adjusting cylinder 324 via fastening components and its output end is a screw, and the inner adjusting cylinder 325 is provided with a nut. When the output end of the adjusting transfer case 327 is engaged with the inner adjusting cylinder 325, the screw and the nut are threadedly engaged. The adjusting motor 326 is preferably a servo motor and is mounted on the adjusting transfer case 327 via fastening components, and its output end is connected to the input end of the adjusting transfer case 327. Next, when the output end of the adjusting distribution box 327 driven by the adjusting motor 326 rotates to the left relative to the adjusting inner cylinder 325, the adjusting outer cylinder 324 moves upward relative to the edging host 2, causing the clamping bracket 320 to move upward along the edging host 2. When the output end of the adjusting distribution box 327 driven by the adjusting motor 326 rotates to the right relative to the adjusting inner cylinder 325, the adjusting outer cylinder 324 moves downward relative to the edging host 2, causing the clamping bracket 320 to move downward along the edging host 2, thereby adjusting the height position of the clamping structure 32. Through the above technical solution, by adjusting the height position of the clamping structure 32, the glass edging machine can be adapted to the processing needs of glass of different thicknesses, increasing the versatility and flexibility of the glass edging machine, which can be understood by those skilled in the art.
