Description

The production equipment of snowslinger specific brush silk

Technical field

The utility model relates to environment clean-keeping tools, is specifically related to a kind of production equipment of snowslinger specific brush silk.

Background technology

In middle and high latitude area, snowslinger can rapidly and efficiently be cleared away deposite snow, is a kind of high-efficiency environmental clean-keeping tools.During snowslinger work, by brush roll, rotarily driving brush silk cleans ground, brush silk is as the rapid wear attrition component of snowslinger, its intensity and toughness have directly determined cleaning effect and use cost, its cross section of existing snowslinger specific brush silk is generally circle or rectangle, and toughness is low, frangibility during use, improve use cost, affected the effect of keeping a public place clean.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of production equipment of snowslinger specific brush silk, and its production efficiency is high, product strength and good toughness.

For solving the problems of the technologies described above, the production equipment of snowslinger specific brush silk of the present utility model, comprise extruder, also comprise the first bosh, baking oven, the second bosh, stretching and drawing machine, shaping baking oven, the second bosh, in the die head of described extruder three of causes between two tangent circle form, maximum outside diameter and the ratio between maximum inner diameter of die head inner edge are: Φ 1: Φ 2=2:1.

The utility model also provides the using method of the production equipment of above-mentioned snowslinger specific brush silk, comprises the following steps:

A, pp material and wire drawing agent are placed in to extruder, are heated to molten condition, then after extruding by die head, successively through the first bosh, baking oven, the second bosh tractive to stretching and drawing machine; Be 3 minutes described first bosh cool time, 50 ± 10 ℃ of water temperatures; 2.5 ~ 3.5 minutes described baking oven heat times, 250 ℃ of temperature;

B, above-mentioned steps gained material are cut and are got product after shaping baking oven, the second bosh output; In described shaping baking oven, temperature is 160 ℃.

In technique scheme, wire drawing agent, after die head is extruded, cools through the first bosh, then heats through baking oven, because the baking oven heat time is shorter, thereby brush the body part temperature of silk lower than the temperature of flange portion, the drawing coefficient of flange is higher than the drawing coefficient of body, thereby its body is without abundant stretching, possesses higher intensity, three flanges, through fully stretching, possess higher toughness, have improved intensity and the toughness of brush silk of the present utility model; Product can draw high and extrude continuously, and production efficiency is high.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Visible as shown in Figure 1, Figure 2, the production equipment of snowslinger specific brush silk of the present utility model, comprise extruder 1, also comprise the first bosh 2, baking oven 3, the second bosh 4, stretching and drawing machine 5, shaping baking oven 6, the second bosh 7, three of the interior causes of die head 10 of described extruder 1 between two tangent circle form, and maximum outside diameter and the ratio between maximum inner diameter of die head 10 inner edges are: Φ 1: Φ 2=2:1.

The shape of the shape of above-mentioned die head 10 and snowslinger specific brush silk matches.

As visible in Fig. 3, Fig. 4, to use the utility model to produce snowslinger specific brush silk, its component is comprised of 90% pp and 10% wire drawing agent by weight; Its structure comprises body 80 and along three uniform flanges 81 of body 80 outer surfaces, on the cross section of brush silk, the outside diameter that the solstics of three described flanges 81 forms with the ratio of the interior circular diameter that closest approach forms is: Φ 1: Φ 2=2:1.

The body 80 of described snowslinger specific brush silk and three flanges 81 are all arranged in parallel along the length direction of brush silk, body 80 and three flange 81 one extrusion moldings.

Three flange 81 outer rims are circular, and along the cross section of brush silk, three flanges 81 are tangent between two.In cross-wise direction, Yi Shuasi center is far point, and it is the cylindrical of Φ 1 that the solstics of three flanges 81 forms diameter, and it is the inner circle of Φ 2 that the near point of three flange 81 combinations between two forms diameter, and Φ 1: Φ 2=2:1.

The utility model also provides and has used the said equipment to produce the production method of snowslinger specific brush silk, comprises the following steps:

A, pp and wire drawing agent are placed in to extruder 1, are heated to molten condition, then after extruding by die head 10, successively through the first bosh 2, baking oven 3, the second bosh 4 tractives to stretching and drawing machine 5; Be 3 minutes described the first 2 cool times of bosh, 50 ± 10 ℃ of water temperatures; Described 2.5 ~ 3.5 minutes 3 heat times of baking oven, 250 ℃ of temperature.

According to the operating rate of stretching and drawing machine 5, by regulating the length of the first bosh 2, can regulate the working time of material in the first bosh 2, in like manner adjustable 3 heat times of baking oven.Its finished product external diameter of snowslinger specific brush silk of the present utility model is controlled at 3mm, and the operating rate 60cm ~ 100cm of stretching and drawing machine 5 is per second.

B, above-mentioned steps gained material are cut and are got product after shaping baking oven 6, the second bosh 7 outputs; The described interior temperature of shaping baking oven 6 is 160 ℃.Described the second bosh 7 room temperatures are cooling.
