Abstract
An open mill comprises a base (1), a bracket (2), a roller (5), pull cord switches (3) and an urgent-stop pull cord (4), and is characterized in that contact switches (7) are fixedly connected to two ends of the lower part of the bracket (2) respectively; and a resetting pedal level device is arranged at the upper ends of the contact switches (7). Therefore, the open mill has the advantages of low manufacturing cost, convenience for operation, simplicity in maintenance, safety and practicability, and is particularly suitable for rubber mixing.
Description
Technical field:
The utility model relates to a kind of rubber heat refining equipment, particularly a kind of open rubber mixing mill.
Background technology:
At present, in rubber is produced, use open rubber heat refining equipment more; Be mill, this equipment roller diameter is big, and power of motor is big; Under roller rotates, rubber, cool glue are squeezed into hot glue, even for guaranteeing heat refining, need manual work on roller, sizing material to be cut upset with cutter; Because of softer behind the sizing material temperature height and viscosity increases,, hand or arm are squeezed off so the as easy as rolling off a log operating personnel's of causing hand is clamped and brought in the roller by sizing material during operation; Even take away life, the mill security incident often appears in rubber industry; The anxious stay cord that stops is only installed in former mill above operating personnel, stops and can stop in case the dangerous pulling of appearance is anxious, but from actual production; Often there is the operative employee below roller, to be squeezed hand; And the below does not have emergency stop device, and therefore, it is very crucial to improve the device security performance.
The utility model content:
The purpose of the utility model is exactly that the mill that a kind of safe effect is good, simple, practical, cost is low will be provided.
The purpose of the utility model is achieved in that a kind of pair of emergency stop device mill; Stop stay cord and form by base, support, roller, pull switch, urgency; The two ends that it is characterized in that described support below respectively are fixedly connected a contact switch, but there is a homing position type treadle device upper end of contact switch.
But the described homing position type treadle of the utility model device is made up of spring, holder, fairlead, guide post, treadle; The upper end of holder is fixedly connected fairlead; Flexibly connect guide post in the fairlead; The upper end of guide post is fixedly connected treadle, and the fairlead outside flexibly connects spring, and spring connects treadle and holder respectively in two ends up and down; Holder is fixedly connected on the two ends of base.
The upper end of described contact switch connects switch contact.
The utility model compared with prior art has the following advantages:
Because adopted the two ends of support below respectively to be fixedly connected a contact switch, but there is the version of a homing position type treadle device upper end of contact switch, thereby; The device security performance improves, and below override type safety device do not influence production, can treadle automatically reset by spring after stepping on; Cost of manufacture is low; Easy to operate, safeguard simple, safe and practical.

The specific embodiment:
During use, start mill, if the needs that stop in emergency are arranged, on can spur the anxious stay cord 4 that stops, can step on safe treadle 12 down, mill is stopped in emergency; Treadle formula emergency stop device principle does, step on treadle 12 after, treadle 12 contact-making switch contacts 6, contact switch 3 control mills outage and brakes on devices make the stall of mill roller.
Claims (4)
1. mill; Stop stay cord (4) and form by base (1), support (2), roller (5), pull switch (3), urgency; The two ends that it is characterized in that described support (2) below respectively are fixedly connected a contact switch (7), contact switch (7) but the upper end homing position type treadle device is arranged.
2. according to the said mill of claim 1; It is characterized in that but described homing position type treadle device is made up of spring (8), holder (9), fairlead (10), guide post (11), treadle (12); The upper end of holder (9) is fixedly connected fairlead (10), flexibly connects guide post (11) in the fairlead (10), and the upper end of guide post (11) is fixedly connected treadle (12); Fairlead (10) outside flexibly connects spring (8), and spring (8) two ends up and down connects treadle (12) and holder (9) respectively.
3. mill according to claim 2 is characterized in that described holder (9) is fixedly connected on the two ends of base (1).
4. mill according to claim 1 is characterized in that the upper end of described contact switch (7) connects switch contact (6).
