Detailed Description
The utility model provides a wane formula band conveyer vertically tears protection device, the device can prevent to tear the fault amplification because of the belt and cause the sticky tape whole to scrap, avoids taking place malignant accidents such as conflagration.
Referring to fig. 1 to 4, the utility model mainly comprises a spring 1, a bracket 2, a main limit switch 3, a stop block 4, a material receiving plate 5, a shaft sleeve 6, a fixing shaft 7, a support 8, a fixing seat 9, a supporting shaft 10, an auxiliary limit switch 11 and an auxiliary bracket 12.
The figure shows that a spring 1 is connected with a bracket 2 and the head end (left end) of a material receiving plate 5, a main limit switch 3 is installed on the bracket 2, and a swing rod and a contact of the main limit switch 3 are positioned about 2-3mm under the material receiving plate 5.
The figure shows that the shaft sleeve 6 is sleeved on the fixed shaft 7, the two shaft sleeves 6 are respectively welded on the two ends of the axis of the material receiving plate 5 and are combined into a whole, and a gap of 3-5mm is formed between the aperture of the shaft sleeve 6 and the diameter of the shaft of the fixed shaft 7.
The figure shows that a support 8 and a fixed seat 9 are installed on a belt conveyor frame, a fixed shaft 7 and a supporting shaft 10 are respectively welded on the support 8 and the fixed seat 9, the horizontal installation height of the fixed shaft 7 is lower than that of the supporting shaft 10, a material receiving plate 5 is positioned above the fixed shaft 7 and the supporting shaft 10, and the supporting shaft 10 is not connected with the material receiving plate 5.
The left and right of the material receiving plate 5 are not equal in height, the material receiving plate 5 is suitable for being made of hard plastics or nylon sheets, the surface is smooth, the weight is light, the strength is high, and the action is flexible.
The protection device is shown in the figure, when in a static state, the spring 1 is in a slight stretching state, the left end of the material receiving plate 5 is pulled up, the lowest point of the inner wall of the shaft sleeve 6 is in contact with the lowest point of the fixed shaft 7, and the right side of the material receiving plate 5 is placed on the supporting shaft 10 in a floating mode, so that the material receiving plate 5 and the horizontal plane of the frame of the belt conveyor form an inclination angle of 2 degrees. The spring 1 is suitable for a light spring with low strength, and the specification and model of the spring 1 are selected according to the weight of the material receiving plate and the shaft sleeve.

The stop block 4 is welded on the bracket 2 and is positioned below the head end (left end) of the material receiving plate 5, so that when the belt 13 is prevented from being longitudinally torn and the material 14 is leaked in a large amount, the head end (left end) of the material receiving plate 5 has overlarge drooping amplitude to cause the damage of the swing arm of the spring 1 and the main limit switch 3, and the protection effect is achieved.
The working process of the utility model is as follows:
the device is arranged at the tail of the belt conveyor and 3-5 meters away from a discharging hopper and below the bearing surface of a belt 13. When the foreign matter that the volume of mixing into ironware equals surpasss feed opening limit size in material 14, the foreign matter vertically tears belt 13, 14 of the material that bears on belt 13 spill hourglass, material 14 that spills hourglass falls on connecing flitch 5, connect the head end (left end) of flitch 5 to remove downwards and extension spring 1, connect the tail end (right-hand member) perk of flitch 5, connect head end (left end) of flitch 5 to touch main limit switch 3, connect tail end (right-hand member) of flitch 5 to touch vice limit switch 11, when main limit switch 3 and vice limit switch 11 all moved the electricity, the conveyer controller made band conveyer shut down to the further expansion of trouble has been prevented.
Because the operation working condition of part belt feeder is relatively poor, there is the raise dust problem, connect flitch 5 not clear up for a long time will produce deposition, deposition phenomenon, these deposition, deposition increase gradually make connect flitch 5 left end produce downward displacement, until the highest point of axle sleeve 6 inner wall contacts with the highest point of fixed axle 7, connect flitch 5 to make main limit switch 3 act, and vice limit switch 11 has not acted yet, in order to avoid the device to produce the malfunction, the conveyer controller only sends the belt and tears alarm signal but does not shut down at this moment, wait to clear up the deposition on the flitch 5 by the manual work, main limit switch 3 swing arm resets, eliminate alarm signal.
The utility model discloses simple structure, convenient to use, operation are reliable, preparation low cost, can effectively detect the vertical tear trouble of belt, avoid the enlarged scale of accident. The adhesive tape of the damaged section can be locally repaired by cold adhesive repairing strips or steel wire tape fillers, hot vulcanization and other modes, so that the equipment maintenance time is shortened, the waste of manpower and material resources is reduced, and the economic benefit is remarkable.
Direct economic benefits:
taking three material yards of the Handrail logistics company as an example, the belt conveyor equipment accounts for 320 belt sleeves, and if the belt conveyor anti-tearing device sold in the purchase market is a belt conveyor anti-tearing device, the price of each belt conveyor anti-tearing device is 5-15 ten thousand yuan, so that the cost is huge. Therefore, the unit self-manufactures the belt conveyor with the length of more than 25 meters, and is additionally provided with the longitudinal belt tearing protection device of the conveyor, 126 sets are additionally arranged in total, and the purchase cost of spare parts is greatly saved. And each cost of the self-made conveyor belt longitudinal tearing protection device is less than 5000 yuan. The spare part purchase cost saved by each conveyor belt longitudinal tearing protection device is calculated according to 3 ten thousand yuan, and the benefit amount is at least 3X 126=378 ten thousand yuan.
According to statistics, the longitudinal tearing fault of the belt in a stock yard of a logistics company occurs 2-4 times per year in nearly 3 years, and the average number of times per year is 3. The belt spare parts replaced by the three material yards of the logistics company due to the longitudinal belt tearing fault are at least 1000 meters each year. After the protective device is used, the probability of the problems is greatly reduced, the purchase price per meter is 434 yuan according to the 1200x7x8/3 model of the high-wear-resistant nylon belt, and the annual benefit amount is at least 1000 x 434=43.4 ten thousand yuan.
