Abstract
The utility model relates to a crashing grinder for waste rubber, which comprises a machine casing, a rubber material propeller, a fixed grinding disc, a rotary grinding disc, a driving belt pulley, cooling devices and a rubber-powder fineness adjusting device driven by a motor. The utility model also comprises a hollow shaft for installing the rotary grinding disc; two bearing seats supporting the hollow shaft are respectively arranged on the upper part and the lower part of the rotary grinding disc and are respectively assembled on the machine casing, and the lower end of the hollow shaft is provided with the driving belt pulley. The grinding surfaces of the fixed grinding disc and the rotary grinding disc have equal conicity, hard alloy rack bars are inlaid and welded on the grinding surfaces and are uniformly distributed on the grinding surfaces, and the helix angles of the rack bars are 12DEG-18DEG. The upper part of the fixed grinding disc is provided with the rubber-powder fineness adjusting device, a rubber-powder fineness adjusting drive motor on the machine casing is started, and then power grinding fineness can be adjusted. Both the fixed grinding disc and the rotary grinding disc are provided with the cooling devices. The utility model is especially used for grinding waste rubber, and has the advantages of high productive efficiency, stable and reliable operation and long service life.
Description
Technical field the utility model relates to solid material and pulverizes grinding machine, particularly a kind of waste rubber powder disintegrator.
The waste rubber powder disintegrator is a kind of special equipment that waste old is recycled.
Background technology is present, there is a kind of rubber and plastic pulverizer to have the shortcoming of unreasonable structure, the dish of going round and round a millstone is equipped with in this machine hollow shaft upper end, and driving pulley is equipped with in the hollow shaft lower end, and the bearing seat of supporting hollow shaft is in the middle part of hollow shaft, it is the supporting structure of a single fulcrum beam, and hollow shaft bears very big moment of flexure, and this just can not guarantee bearing, the hollow shaft and the due running accuracy of dish of going round and round a millstone, stability, and influence service life of complete machine.In addition, this machine carbide alloy tooth bar spiral angle number of going round and round a millstone on dish and the fixed millstone flour milling is too small, influences the production efficiency of complete machine.
In addition, there is the special-purpose pulverizer of a kind of waste old also to have the shortcoming of unreasonable structure, this machine rubber powder fineness adjusting device is with the go round and round a millstone gap length of dish and fixed millstone of the mode adjustment of the axial displacement that changes the dish of going round and round a millstone, for this reason, bearing and the axle journal of supporting hollow shaft or with the cooperating of bearing saddle bore for movingly, to be used to regulate the axial displacement of hollow shaft and movable grinding disc, this structure just more can't guarantee the running accuracy and the service life of the hollow shaft and the dish of going round and round a millstone.
Summary of the invention is for solving the problem that above-mentioned pulverizer exists, and the utility model provides a kind of improved waste rubber powder disintegrator.The utility model has changed the position and the structure Design of hollow shaft upper bearing (metal), makes the hollow shaft and the dish of going round and round a millstone stressed rationally, also changes the arrangement that having designed carbide alloy tooth bar on go round and round a millstone dish and the fixed millstone flour milling simultaneously.
A kind of pulverizing grinding machine that is used for waste old, its structure mainly comprises: casing, sizing material propeller, hollow shaft, fixed millstone, the dish of going round and round a millstone, driving pulley, rubber powder fineness adjusting device and cooling device.It also comprises the hollow shaft that the dish of going round and round a millstone is installed, and an empty bearing block branch that holds axle is located at the upper and lower of dish of going round and round a millstone, and is assemblied on the casing respectively.Brearing bore adopts the interference fit standard with cooperating of axle journal, and bearing outside diameter adopts the interference fits standard with cooperating of bearing saddle bore.Driving pulley is equipped with in the hollow shaft lower end.Going round and round a millstone, welding-on has the carbide alloy tooth bar on the dish and the flour milling of fixed millstone, the uniform flour milling of tooth bar, and the helical angle of tooth bar is 12 °～18 °.Rubber powder fineness adjusting device is equipped with on the top of fixed millstone, and the drive motors of this device is located on the casing, starts drive motors, can adjust fineness of grinding.The fixed millstone and the dish of going round and round a millstone all are provided with cooling device.
The beneficial effects of the utility model are appropriate design of hollow shaft block bearing position of the present utility model and structure, make steady, reliable, the life-span prolongation of this machine running.The change of carbide alloy tooth bar arrangement on dish and the fixed millstone flour milling of going round and round a millstone makes the production efficiency raising of this machine.
Appended drawings is a kind of structural representation of waste rubber powder disintegrator.
The specific embodiment is referring to accompanying drawing, and a kind of waste rubber powder disintegrator comprises casing 2, the fixed millstone 3 of installing, go round and round a millstone dish 4, sizing material propeller 1, meal outlet 10 in casing 2.Hollow shaft 5 is installed in the centre bore of the dish 4 of going round and round a millstone, and supports the bearing block 7,13 of hollow shaft 5, divides to be located at the two ends up and down of dish 4 of going round and round a millstone, and is installed in the upper and lower of casing 2 respectively.Brearing bore adopts the interference fit standard with cooperating of axle journal, and bearing outside diameter adopts the interference fits standard with cooperating of bearing saddle bore.Driving pulley 12 is equipped with in the hollow shaft lower end.Hollow shaft 5 upper and lower sides also are equipped with swivel joint 6,11.Cooling water enters in the dish cavity of going round and round a millstone by the swivel joint 11 of lower end, discharges by the swivel joint 6 of upper end again.
The go round and round a millstone dish 4 and the tapering of fixed millstone 3 flour millings equates that welding-on has the carbide alloy tooth bar on the flour milling, the uniform flour milling of tooth bar, and the helical angle of tooth bar is 12 °～18 °.
Be equiped with rubber powder fineness adjusting device 9 on fixed millstone 3 tops, the rubber powder fineness that starts on the casing is regulated drive motors 8, can change the axial displacement of fixed millstone 3 by the transmission mechanism in the casing,, reach the requirement of adjusting the rubber powder fineness with go round and round a millstone gap length between dish 4 and the fixed millstone 3 of adjustment.
Fixed millstone 3 inner chamber cooling water gateways are opened in the two sides of this mill respectively.
In use the scrap rubber material is pushed to go round and round a millstone in the casing by sizing material propeller 1 and carries out grinding between the dish 4 and the flour milling of fixed millstone 3, cooling water feeds respectively in the cavity of the fixed millstone and the dish of going round and round a millstone simultaneously, to reduce the heat that grinding process produces, the electrical control button of pressing the adjustment of rubber powder fineness can be adjusted the fineness of grinding rubber powder.Rubber powder after the grinding is by the external air-introduced machine sucking-off of meal outlet 10.
