Description

Technical Field

[0001] The utility model relates to the technical field of glass production equipment, in particular to a glass kiln feeding device. Background Art

[0002] The first step in glass manufacturing is to heat and melt the raw materials. During the heating process, the raw materials gradually melt and mix together to form a viscous liquid, which is the molten glass. This process is usually completed in a glass kiln. The temperature in the glass kiln can reach over 1500 degrees Celsius. Therefore, the traditional conveyor belt cannot complete the feeding and conveying process. A special swing-rod feeder is required to push the material into the furnace. However, the general swing-rod feeder has a fixed length of swing rod, which is only suitable for working in front of the glass kiln it is equipped with. It has poor applicability and cannot be adjusted. A new feeding device is needed to solve the above problems. Utility Model Content

[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] like Figures 1 to 3 As shown, the glass kiln feeding device includes a frame 1, and the frame 1 includes four columns 101. The four columns 101 are installed on a chassis 102 with universal wheels. An anti-collision strip 12 is embedded in the side of the chassis 102. A sleeve arm 4 is hinged in the middle of the connecting beam between the columns 101 on both sides. The head end of the sleeve arm 4 is slidably connected to the cylinder body of the telescopic cylinder 5 in the arm cavity. The cylinder body can be fixed by positioning bolts. The output ends of the two telescopic cylinders 5 are connected to a push plate mechanism. The push plate mechanism includes a push plate 7. Both sides of the push plate 7 are penetrated by waist holes 701 opened along the direction of the plate body. The sides of the push plate 7 are provided with screw hole groups 702 along both sides of the waist holes 701. The waist holes 701 are slidably connected to a sleeve 8. The flanges at both ends of the sleeve 8 are connected to the screw hole groups 702 by bolts. The sleeve 8 is rotatably connected to a push rod 9, and both ends of the push rod 9 are bent and connected to the piston rod ends of the telescopic cylinder 5.

[0017] In this embodiment, the bottom surface of the rear end of the sleeve arm 4 contacts the top of the spring seat 6, and a pressure rod 401 is connected between the opposite surfaces of the rear ends of the two sleeve arms 4. A downward pressure cylinder 14 is provided above the middle of the pressure rod 401, and the cylinder body of the downward pressure cylinder 14 is installed in the middle of the crossbeam 103 above the two back columns 101. When the output end of the downward pressure cylinder 14 pushes the pressure rod 401 downward, the two sleeve arms 4 compress the spring seat 6 downward, and the sleeve arms 4 rotate around the hinge point, and the push plate mechanism is lifted; when the output end of the downward pressure cylinder 14 contracts, the spring seat 6 pushes the sleeve arm 4 upward to a horizontal position.

[0018] In this embodiment, a filling mechanism is provided on the top of the frame 1, and the convex edges on both sides of the feed hopper 2 in the filling mechanism are mounted on two cross beams 103, and two crushing rollers 10 are arranged side by side in the discharge pipe mouth of the feed hopper 2. The rotating shaft of the crushing roller 10 is connected to the output end of the crushing motor 11, and the crushing motor 11 is installed on the side wall of the discharge pipe of the feed hopper 2. A conveyor belt 3 is obliquely arranged below the bottom outlet of the feed hopper 2, and the output end of the conveyor belt 3 is located at the rear side of the push plate 7. The conveyor belt 3 is installed in the lifting plate 13, and the baffles on both sides of the lifting plate 13 are higher than the belt surface of the conveyor belt 3. The slider 1301 on the outer side of the baffle is vertically slidably connected with the slide rail 104 on the inner side of the column 101.

[0019] The working principle of the utility model is as follows:

[0020] Push the device to the furnace mouth of the glass kiln where material needs to be added, keep the sleeve arm 4 horizontal, rotate the push plate 7 to adjust its inclination, slide the sleeve 8 to the appropriate position in the waist hole 701 and fix it with bolts. At this time, the bottom of the push plate 7 contacts the bottom surface of the furnace mouth, start the telescopic cylinder 5 to the maximum stroke, slide the cylinder body of the telescopic cylinder 5 to the appropriate position and fix it to ensure that the push plate 7 can push the material into the inner furnace. When feeding, raw material particles are put into the feed hopper 2, the crushing motor 11 is started to drive the crushing roller 10 to crush the raw material particles, and the crushed raw material falls onto the conveyor belt 3 and is transported to the push plate 7. The downward pressure cylinder 14 moves downward to briefly lift the push plate 7 and then resets, so that the raw material is pushed to the front of the push plate 7, and the telescopic cylinder 5 is started. The push plate 7 pushes the raw material into the furnace, and then the downward pressure cylinder 14 moves downward again to lift the push plate 7, and the telescopic cylinder 5 retracts the push plate 7. At this time, the subsequent raw material is transported to the front of the push plate 7 again, and the downward pressure cylinder 14 resets to start the next cycle. The utility model can repeatedly transport glass raw material powder to the kiln to complete feeding through the steps of pushing, lifting, shrinking, and resetting. The position of the telescopic cylinder 5 used for pushing can be adjusted as needed to adapt to the different pushing distances of various types of kilns.
