Description

Self-lubricating chuck of bottle making machine

Technical Field

The utility model belongs to the technical field of the bottle-making machine, concretely relates to bottle-making machine self-lubricating formula chuck.

Background

The clamping head for clamping the bottle body in the prior bottle making machine generally comprises a hollow shaft sleeve, a clamping head disc fixedly arranged at the end part of the shaft sleeve, a sliding sleeve sleeved on the shaft sleeve and a clamping jaw hinged on the sliding sleeve, wherein the clamping jaw is arranged in a sliding groove of the clamping head disc in a sliding way. For example, the direct-push type automatic centering chuck of the bottle making machine disclosed in the publication No. CN 2385867Y and the adjustable chuck assembly of the bottle making machine disclosed in the publication No. CN 2567213Y. When the clamping device works, the sliding sleeve moves up and down to drive the clamping jaws to slide along the clamping chuck sliding grooves, so that the clamping jaws are mutually folded or unfolded to finish the action of clamping or unloading bottles.

When the clamping head clamps or unloads a bottle under the control of a bottle making machine controller, the clamping jaws slide in the sliding grooves of the clamping head disc, so that liquid lubricating oil is usually injected between the clamping head and the clamping head disc regularly in actual production in order to reduce the friction resistance between the clamping jaws and the sliding grooves and reduce the abrasion of the clamping head disc to the clamping jaws during sliding. Although the lubricating mode can reduce the friction between the clamping jaw and the inner wall of the sliding groove of the chuck plate to a certain degree, the lubricating mode has the following defects in actual production:

one is frequent maintenance, which affects production efficiency. In order to ensure that the clamping jaws slide flexibly in the sliding grooves of the chuck plate, liquid lubricating oil is injected between the clamping jaws and the sliding grooves by workers at intervals of 2-3 days generally; especially when the equipment operation time is longer, the oil injection time is even shortened to 1 day. The mode has high oiling frequency, frequent maintenance and labor consumption; moreover, because the operating chuck is in a rotating state, the machine must be stopped to finish the oil injection operation, thereby reducing the bottle-making production efficiency.

Secondly, the glass bottle is easily polluted. When the equipment is operated, the liquid lubricating oil injected between the clamping jaw and the chuck plate is easy to drip on the surface of the glass bottle clamped by the clamping jaw, so that the glass bottle is polluted and the surface quality of the glass bottle is influenced.

And thirdly, the positioning accuracy of the clamping jaw is influenced. When the clamping jaws slide in the sliding grooves of the chuck plate at high frequency, the temperature of the contact surfaces of the clamping jaws and the sliding grooves of the chuck plate rises to cause the evaporation of liquid lubricating oil to form solid carbon deposition, so that the friction resistance between the clamping jaws and the inner walls of the sliding grooves of the chuck plate is increased, the flexibility of the clamping jaws sliding in the sliding grooves is influenced, and the abrasion to the clamping jaws is also caused. When the accumulation of solid carbon is excessive, the accuracy of sliding positioning of the clamping jaws in the sliding grooves is influenced, so that the positioning accuracy of the clamping jaws during bottle clamping and bottle unloading is influenced.

SUMMERY OF THE UTILITY MODEL

For solving exist among the prior art more than not enough, the utility model aims at providing a bottle-making machine self-lubricating formula chuck to reach and be convenient for maintain, reduce the purpose of polluting the glass bottle and ensure clamping jaw location precision.

In order to achieve the above object, the utility model adopts the following technical scheme: a self-lubricating chuck of a bottle making machine comprises a chuck plate and a clamping jaw arranged in a sliding groove of the chuck plate in a sliding mode, wherein a lubricating piece is fixedly arranged between the clamping jaw and the sliding groove of the chuck plate.

As another limitation of the present invention, the lubricating member is a metal sleeve fixedly mounted on the clamping jaw.

As a further limitation of the present invention, the outer wall of the metal sleeve is embedded with solid lubricant at a plurality of positions.

As a still further limitation of the present invention, the solid lubricant is any one or more of graphite, boron nitride, molybdenum disulfide, and glass beads.

As a further limitation of the present invention, the lubricating member is a copper sleeve fixedly mounted on the clamping jaw.

Since the technical scheme is adopted, compared with the prior art, the utility model, the beneficial effect who gains is:

(1) the utility model changes the original liquid lubrication mode between the clamping jaw and the chuck plate sliding groove into the self-lubrication mode realized by the existing mechanical structure, realizes the long-term good self-lubrication effect between the clamping jaw and the chuck plate sliding groove, does not need to adopt manpower to frequently carry out regular maintenance between the clamping jaw and the chuck plate, reduces the maintenance times, ensures the normal operation of the chuck, and ensures the production efficiency of the bottle making machine; and, the utility model discloses still avoided the condition of liquid lubricating oil pollution glass bottle to take place, ensured clamping jaw sliding positioning's in the spout precision, effectively guaranteed product quality.

(2) The utility model provides a lubricated piece adopts the copper sheathing, and hardness is high, the wearability is good, corrosion resistance is strong, especially also can guarantee good sliding property and self-lubricating property under the condition that lacks emollient. Moreover, the copper sleeve fixedly arranged on the clamping jaw also prevents the clamping jaw from directly contacting with the inner wall of the chuck plate, so that the clamping jaw and the chuck plate cannot be relatively worn, the positioning accuracy of the chuck is further ensured, and the service life of the chuck is prolonged.

(2) The utility model discloses a metal covering/copper sheathing on many places inlay and be equipped with solid lubricant, further improved the lubricated effect between clamping jaw and the chuck dish to still can not produce the carbon deposit, compare lubricating oil and do not have any side effect, the effect is better, the performance is more excellent.

(3) The utility model discloses lubricated maintenance easy operation only need change on the clamping jaw metal covering/copper sheathing can, maintain the cycle length moreover, according to metal covering/copper sheathing life, can change once every half an year.

The utility model is suitable for an install and regard as bottle-making machine A portion chuck at bottle-making machine A portion deep bid, also be applicable to and install as bottle-making machine B portion chuck at bottle-making machine B portion deep bid for press from both sides and get the glass bottle.
