When the clamp works, the inner container 100 is placed firstly, then the upper outer container 200 is placed, in the process of placing the upper outer container 200, the inner wall of the upper outer container is contacted with the indicating ball 820 to enable the indicating ball to rotate, so that the color of the indicating ball 820 observable by a worker from the outside is changed, and in the process of placing or processing the upper outer container, if the indicating ball 820 is reset, the upper outer container is not clamped or is locally loosened, and the upper outer container is not clamped: in the process of placing the upper liner, if the condition that the individual indication ball is not rotated (or is inconsistent with the rotation state of other indication balls) occurs, whether the upper liner is biased or the upper liner is obviously deformed should be checked.
The working principle of the device is as follows:
1. the clamp 3 in the area of the automatic feeding device 6 is in a vertical state, the turntable drives a clamp in the vertical state to come right above a lifting cylinder 620 and is suspended, the end part of a movable plugboard 630 is inserted into an annular clamping groove 3731, then the lifting cylinder 620 is lifted to jack a main shaft lever 312 to enable an upper sliding table 371 to move upwards, a first clamping group is opened, a gripper grabs an inner container to be placed in the first clamping group, the movable end of the lifting cylinder 620 is lowered, the upper sliding table 371 is reset, and the inner container 100 is clamped by the first clamping group; then the movable plugboard 630 controls the lower sliding table 373 to move downwards, the second clamping group is opened, the mechanical claw grabs the upper outer liner 200 to be placed in the second clamping group, the movable plugboard 630 controls the lower sliding table to move upwards for resetting, and the upper outer liner 200 is clamped by the second clamping group; at this time, the upper liner 200 is sleeved outside the liner 100, and the openings of the upper liner and the liner are nearly flush, which is called as a liner kit 300;
then the turntable 2 rotates, and when the turntable enters the second track section control area 512, the clamp is turned over to be in a horizontal state, and the bottle mouth of the liner sleeve 300 is outwards; as the turntable 2 rotates, when the transmission device 7 contacts with the transmission gear 360, the clamp is driven to rotate so as to enable the glass liner sleeve 300 to rotate, and meanwhile, the bottle mouth of the glass liner sleeve starts to be burned by flame; when the liner sleeve runs to the middle section or the rear section of the control area of the second track section 512, the bottle mouth breaks away from flame, and a worker or a machine presses the bottle mouth by adopting a special die to fuse the bottle mouths of the upper liner and the liner;
the turntable 2 continues to rotate, the liner sleeve 300 is separated from the control area of the second track section 512 and enters the control area of the first track section 511, and the clamp 3 is in a vertical state again; when the clamp moves to the automatic feeding device area, the jacking cylinder and the movable plugboard respectively control the first clamping group and the second clamping group to open simultaneously, and at the moment, the glass liner sleeve is taken away, and one glass liner sleeve is processed; and (5) circularly processing the materials.
Function of the indication device: in the processing process, the holding stationary phase of the upper outer liner 200 is easier to generate unstable condition than that of the inner liner, so that the monitoring of the clamping of the upper outer liner is biased; when the upper outer liner 200 is placed, the inner wall of the upper outer liner contacts with the indication ball 820 to enable the indication ball to rotate, so that the color of the indication ball 820 which can be observed by a worker from the outside is changed, and if the indication ball 820 is reset in the process of placing or processing and rotating the upper outer liner, the upper outer liner is not clamped or is loose locally: in the process of placing the upper liner, if the individual indication balls do not rotate or are inconsistent with the rotation states of other indication balls, whether the upper liner 820 is biased or the upper liner is obviously deformed should be checked. When the processing of the liner set 300 is completed and the gripper takes away the liner set, the first clamping set and the second clamping set are opened simultaneously, at this time, the supporting rod 810 on the first clamping set is bent to adapt to the movement of the first clamping set, and after the liner set is taken out, the ball is instructed to reset.
