Description

A plastics breaker for PVC processing

Technical Field

The utility model relates to a PVC processing equipment field, concretely relates to a plastics breaker that is arranged in PVC processing lines farming.

Background

PVC is a material for short, the main component is polyvinyl chloride, and other components are added to enhance the heat resistance, toughness and ductility of the PVC. The top layer of the surface film is paint, the middle layer is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is enjoyed, popular and widely used in the world today. Its global usage is second highest among various synthetic materials. It is only in 1995 a year that PVC has been statistically produced in europe at around five million tons and consumed at five million thirty million tons. In germany, the production and consumption of PVC averages one hundred and forty million tons.

The preparation process of the PVC related material mainly comprises raw material preparation, mixing and feeding, extrusion molding, soaking and cooling, traction cutting, detection and packaging and the like, wherein the raw material preparation is to generally crush finished PVC particles or crushed materials and then mix the crushed materials with an auxiliary agent, and the crushing condition of the PVC raw material directly influences the mixing uniformity of the PVC raw material and the auxiliary agent and the quality of subsequent extrusion molding, so that the effect of the crushing process needs to be ensured.

A breaker that is used for PVC production at present generally utilizes the crushing roller of relative setting to carry out crushing operation, but because elasticity that the PVC material has, the characteristic of being heated and becoming soft, lead to the crushing roller sometimes can only be with PVC raw materials suppression deformation, rather than smashing, just so lead to the effect of shredding not good, influenced the quality of follow-up PVC product.

SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides a plastics breaker for PVC processing for solve current breaker because of elasticity that PVC has and be heated the softening nature and can not carry out effectual smashing to the PVC raw materials, lead to the not good problem of PVC product quality of production.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a plastics breaker for PVC processing, includes the casing, the casing is inside to have set gradually feedstock channel, roll the passageway, smash the passageway and break up the passageway along the direction of feed, the vertical setting of feedstock channel, its top communicates the casing outside, roll the passageway, smash the passageway and break up and be provided with respectively in the passageway and roll mechanism, rubbing the passageway downward sloping, roll the mechanism and include that the perpendicular to rolls two running rollers that the passageway direction set up relatively from top to bottom, smash the vertical setting of passageway, and crushing mechanism includes the crushing roller that two levels set up side by side, break up the passageway setting and smash up the passageway below, break up the axis of rotation that the mechanism includes vertical setting and the pole that breaks up of horizontal installation in the axis of rotation.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model comprises a rolling mechanism and a crushing mechanism which are arranged in sequence, wherein a roller in the rolling mechanism can roll PVC raw materials into a flat shape and then enter a crusher, the stress surface of the materials in the flat shape in a crushing roller is larger, so that the materials can be better crushed by the crushing roller, the situation of leakage between the crushing rollers due to elasticity is not easy to occur, the crushing effect on the raw materials is further improved, and the product quality is correspondingly improved;

2. the utility model discloses still be equipped with and break up the mechanism, break up the pole through the level pivoted, strike vertical kibbling raw materials that drop to will smash the in-process and bind and further break up at a heap partial material, guarantee that the raw materials dispersion is even thorough, so that the better mixture of auxiliary agent.

Drawings

Fig. 1 is a side sectional view of the present invention;

FIG. 2 is a top view of the roller of the rolling mechanism of the present invention;

in the figure: the device comprises a shell 1, a feeding channel 2, a rolling channel 3, a crushing channel 4, a scattering channel 5, an air cooler 6, a feeding funnel 21, a roller 31, a crushing roller 41, a rotating shaft 51 and a scattering rod 52.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

Example (b):

as shown in fig. 1 and 2, the utility model provides a plastics breaker for PVC processing, including casing 1, casing 1 is inside to have set gradually feedstock channel 2 along the direction of feed, roll passageway 3, smash passageway 4 and break up passageway 5, the vertical setting of feedstock channel 2, its top is communicated casing 1 outside and is connected with feed hopper 21 to add the PVC raw materials in the breaker.

Wherein roll the passageway 3, smash the passageway 4 and break up and be provided with respectively in the passageway 5 and roll the mechanism, crushing mechanism and break up the mechanism, roll 3 downward sloppings of passageway, roll the mechanism and include that perpendicular to rolls two running rollers 31 that 3 directions relative settings from top to bottom of passageway, in the preferred scheme, the roll surface of two running rollers 31 is close to the bottom surface that rolls passageway 3, wherein the most part of running roller 31 is buried underground in casing 1 inside down, only the subtotal at top exposes to rolling in the passageway 3, it then most part is located and rolls in passageway 3 to go up running roller 31, the subtotal is located casing 1, ensure like this that the raw materials can get into the seam that rolls between two running rollers 31, the operation of rolling that lasts can not take place the raw materials and pile up. In addition, the surfaces of the two rollers 31 are wavy, and the waves on the two rollers 31 are mutually meshed, so that compared with a smooth surface, raw materials can better enter a rolling surface.

The crushing channel 4 is vertically arranged in this embodiment, and the crushing mechanism includes two horizontally juxtaposed crushing rollers 41. In the present embodiment, it is preferable that one half of the crushing roller 41 near the inner wall of the crushing channel 4 is embedded in the casing 1, and the other half is closely adjacent to the crushing roller 41, so that the raw material will pass through the crushing area in the middle of the crushing roller 41 when falling down.

In a further aspect, the scattering channel 5 is disposed below the pulverizing channel 4, and the scattering mechanism includes a rotating shaft 51 disposed vertically and a scattering rod 52 horizontally mounted on the rotating shaft 51. It should be noted that the scattering channel 5 is downwardly inclined and has a larger vertical height at its upper and lower sides, so that the vertical portions at its left and right ends have coplanar portions, the rotating shaft 51 is mounted on the coplanar portions, and the scattering rod 52 can cover the lower position of the pulverizing channel 4 when rotating, thereby hitting the pulverized material which falls vertically.
