Description

Technical Field

[0001] The utility model relates to the technical field of glass edge breaking devices, in particular to a cold end edge breaking roller transmission device for a float glass line. Background Art

[0002] The forming process of float glass production is completed in a tin bath with protective gas. The molten glass flows continuously from the pool kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the molten glass spreads and flattens on the tin liquid surface to form a flat upper and lower surface. After hardening and cooling, it is led to the transition roller table. The rollers of the roller table rotate to pull the glass ribbon out of the tin bath and into the annealing kiln. After annealing and cutting, float glass products are obtained.

[0003] At present, in the production of float glass, the cold end equipment mainly performs various inspections, cutting / cutting, surface protection, stacking and boxing of the annealed glass ribbon in the production process, as well as the transportation of these processes. Float glass products need to be edge-bent by cold end equipment after processing. The traditional float glass edge-bent device is installed on the edge-bent conveyor roller; its position is after the horizontal breaking machine, which breaks the glass ribbon horizontally along the horizontal cutting and scratching marks to form small pieces of glass plates, which then enter the conveyor roller area.

[0004] The existing cold end bending roller transmission mechanism adopts a worm gear transmission, which has low transmission efficiency. Because the worm on the transmission shaft is not easy to replace, in order to protect the worm, the turbine is made of nylon. The turbine wears quickly and needs to be replaced frequently, which affects production output. Summary of the invention

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a float glass line cold end edge bending roller transmission device to increase transmission efficiency and avoid reducing production efficiency due to frequent replacement of turbine worm gears.

[0008] A plurality of rollers arranged evenly are vertically connected to the transmission shaft, and the transmission shaft is connected to the helical gear with unquenched tooth surface through the helical gear with hardened tooth surface, and the helical gear with unquenched tooth surface is connected to one end of the roller; a roller support beam is provided below the roller, and the roller is fixed on the roller support beam; the roller support beam is slidably arranged on the ground beam guide rail.

[0009] Furthermore, one end of the edge breaking mechanism is fixed on the frame, and the other end is arranged on the transmission shaft.

[0010] Furthermore, the reduction motor is connected to the transmission shaft via a synchronous belt.

[0011] Furthermore, two fixed roller bearing seats are sleeved on the roller, and two ends of the roller are fixed on the roller support beam through the fixed roller bearing seats.

[0012] Furthermore, the roller support beam is slidably arranged on the ground beam guide rail through a roller support beam supporting wheel group.

[0013] Furthermore, the ground beam guide rail is fixed on the ground through a beam guide rail fixing assembly.

[0014] Furthermore, when the length of the transmission shaft is not enough, multiple transmission shafts are set to be linked, and a roller closing and separating motor is set between two adjacent transmission shafts, and the roller closing and separating motor is connected to the end of the transmission shaft through a coupling.

[0015] Furthermore, the transmission shaft is provided with at least one seat bearing.

Example 1

[0026] See also Figure 1-5 , Figure 1 The structural schematic diagram of the cold end edge bending roller transmission device of the float glass line of the utility model is drawn.

[0027] The transmission shaft 3 is vertically connected to a plurality of rollers 6 that are evenly arranged. The transmission shaft 3 is connected to a helical gear 5 with an un-hardened tooth surface via a helical gear 4 with a hardened tooth surface. The helical gear 5 with an un-hardened tooth surface is connected to one end of the roller 6 .

[0028] A roller support beam 11 is provided below the roller 6, and two fixed roller seat bearings 12 are provided on the roller 6. Both ends of the roller 6 are fixed to the roller support beam 11 through the fixed roller seat bearings 12; the roller support beam 11 is slidably set on the ground beam guide rail 14 through the roller support beam support wheel group 13, and the ground beam guide rail 14 is fixed to the ground through the beam guide rail fixing assembly 15.

[0031] Working principle:

[0032] The cold end edge bending roller is the main equipment for removing the edge of float glass. The edge of the cut glass plate is removed by the edge bending mechanism 7 on the edge bending roller. The ground beam guide rail fixing assembly 15 fixes the ground beam guide rail 14 at a certain elevation. The roller support beam support wheel assembly 13 is installed on the roller support beam 11.
