Abstract

An open mill with double emergency stop devices includes a base (1), a frame (2) and a roll (5), and is characterized in that a dragline emergency stop device is fixed at the upper end of the frame (2), two contact switches (7) are fixedly connected to the two ends below the frame (2) respectively, upper ends of the contact switches (7) are connected with switch contacts (6), and a resettable pedal lever device is fixedly connected onto the base (1). As a result, the open mill with the two sets of safety devices improves the safety performance, reduces the manufacture cost, is convenient to operate, is simple to maintain, is safe and practical, and is particularly suitable for rubber mixing of the open mill.

Description

Two emergency stop device mills

Technical field:

The utility model relates to a kind of rubber heat refining equipment, the two emergency stop device mills of particularly a kind of open rubber.

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; Former mill does not have emergency stop (apparatus).

Summary of the invention:

The purpose of the utility model is exactly that two emergency stop device mills 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; Form by base, support, roller; It is characterized in that described support upper end is fixedly connected the stay cord emergency stop device; The two ends of its below respectively are fixedly connected a contact switch, and the contact switch upper end connects switch contact, but on base, is fixedly connected a homing position type treadle device.

Described stay cord emergency stop device stops stay cord by pull switch, urgency to be formed, and pull switch is fixedly connected on the two ends of support, connects the anxious stay cord that stops between the pull switch.

But described homing position type treadle 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 utility model compared with prior art has the following advantages:

Because adopted the support upper end to be fixedly connected the stay cord emergency stop device, the two ends of its below respectively are fixedly connected a contact switch, the contact switch upper end connects switch contact, but on base, is fixedly connected the version of a homing position type treadle device; Therefore, two cover safety devices have been arranged, the device security performance improves, and below override type safety device does not influence production; Can treadle automatically reset by spring after stepping on, thereby cost of manufacture be low; Easy to operate, safeguard simple, safe and practical.

1, base 2, support 3, pull switch 4, anxious stay cord 5, roller 6, switch contact 7, contact switch 8, spring 9, holder 10, fairlead 11, guide post 12, the treadle of stopping

The specific embodiment:

Base 1 two ends are fixedly connected support 2, respectively are fixedly connected pull switch 3 in the upper end of support 2, connect the anxious stay cord 4 that stops between the pull switch 3; Roller 5 is connected the middle part of support 2, and the two ends of support 2 belows respectively are fixedly connected a contact switch 7, and contact switch 7 upper ends connect switch contact 6; On the base 1 of contact switch 7 lower ends, respectively be fixedly connected a holder 9; The middle part of 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 outsides flexibly connect spring 8, and spring connects treadle 12 and holder 9 respectively in two ends about in the of 8.

During use, start mill, if the needs that stop in emergency are arranged, on can spur the anxious stay cord 4 that stops, suddenly stop stay cord 4 and drive pull switches 3, can mill outage and brakes on device be made the stall of mill roller; Under can step on safe treadle 12, treadle 12 contact-making switch contacts 6, switch contact 6 touches contact switch 7, contact switch 7 makes mill outage and brakes on device; Make the stall of mill roller, owing to adopted two cover safety devices, the device security performance improves; And below override type safety device do not influence production, can treadle automatically reset by spring after stepping on, and cost of manufacture is low; Easy to operate, safeguard simple, safe and practical.
