Abstract
The utility model discloses a heat-seal mechanism, including the frame, go up mould and lower mould, it is connected with the lift part that drives its lift to go up the mould, its characterized in that the stroke that the mould goes up and down on the lift part drive divide into working stroke and maintenance stroke, the lift part is including pressure cylinder and control valve, pressure cylinder is including pre-compaction part and pressure boost part, the control valve is including the control pre-compaction part admit air and carminative A valve, the control pressure boost part admit air and carminative C valve and prevent that the pre-compaction part from admitting air and exhausting the valve B who flows backward. When the upper die of the utility model is removed for heat sealing operation, the pressure cylinder controls the lifting of the upper die to be in a working stroke, the distance between the upper die and the lower die is smaller, and the stroke is short and the efficiency is high; when the heat sealing mechanism works, the upper die is recovered to the maintenance stroke by the pressure cylinder, namely the upper die is driven to be positioned at the maintenance station by the pressure cylinder, the upper die is far away from the lower die, the distance between the upper die and the lower die is increased, and the operation of workers is facilitated.
Description
Technical Field
The utility model relates to an improvement of a heat sealing mechanism, in particular to a heat sealing mechanism of a paper-plastic packaging machine.
Background
In order to improve the working efficiency, the lifting stroke of the upper die of the heat sealing mechanism is shortened as much as possible, so that the distance between the upper die and the lower die is smaller, and inconvenience is brought to the cleaning and maintenance work of the heat sealing mechanism.
Disclosure of Invention
In view of the technical problem who exists among the background art, the utility model aims at providing a heat-seal mechanism that neither influences work efficiency, is convenient for maintain work simultaneously again.
In order to solve the technical problem, the utility model discloses a following technical scheme: this kind of heat-seal mechanism, including the frame, go up mould and lower mould, it is connected with the lift part that drives its lift to go up the mould, its characterized in that the stroke that the lift part drive was gone up and down is divided into working stroke and maintenance stroke, the lift part is including pressure cylinder and control valve, pressure cylinder is including pre-compaction part and pressure boost part, the control valve is including the control pre-compaction part admit air with carminative A number valve, the control pressure boost part admit air and carminative C number valve and prevent that the pre-compaction part from admitting air and exhausting the valve of No. B who flows backward.
The valve A and the valve C are electromagnetic valves.
The valve B is a check valve.
The valve B is arranged on an air inlet path of the pre-pressing part.
When the upper die of the utility model is removed for heat sealing operation, the pressure cylinder controls the lifting of the upper die to be in a working stroke, the distance between the upper die and the lower die is smaller, and the stroke is short and the efficiency is high; when the heat sealing mechanism works, the upper die is recovered to the maintenance stroke by the pressure cylinder, namely the upper die is driven to be positioned at the maintenance station by the pressure cylinder, the upper die is far away from the lower die, the distance between the upper die and the lower die is increased, and the operation of workers is facilitated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the pressurizing cylinder of the present invention.
Detailed Description
The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. The heat-sealing mechanism comprises a rack, an upper die 2 and a lower die 3, wherein the upper die 2 is connected with a lifting component for driving the upper die to lift, the stroke of the lifting component for driving the upper die 2 to lift is divided into a working stroke and a maintenance stroke, the working stroke is the stroke of the upper die during heat sealing, the working stroke is shorter, the heat-sealing efficiency is higher, the maintenance stroke is the stroke of the upper die in a standby state, the maintenance stroke is long, the upper die 2 is far away from the lower die 3, and the distance between the upper die and the lower die is large, so that workers can conveniently clean and maintain; the lift part is including pressure cylinder 1 and control valve, pressure cylinder is including pre-compaction part 5 and pressure boost part 6, the control valve is including the pre-compaction part 5 admit air and carminative A number valve 7, the control pressure boost part admit air and carminative C number valve 9 and prevent pre-compaction part admit air and exhaust backflow's B number valve 8, A number valve 7 and C number valve 9 are the solenoid valve, B number valve 8 is the check valve, B number valve 8 sets up on the route of admitting air of pre-compaction part 5. The air inlet of the pre-pressing part 5 is controlled by the valve A7 and the valve B8, the high point of the working stroke of the pressure cylinder is controlled, the valve C9 controls the low point of the working stroke, namely, when the heat sealing operation is carried out, the valve A7 enables the pre-pressing part 5 of the pressure cylinder to operate, the piston rod of the pressure cylinder extends out, the upper die 2 moves downwards to a station to be heat sealed, the valve B8 prevents the air backflow of the pre-pressing part, so that the valve A7 cannot enable the piston rod to retract, the upper die 2 cannot move upwards to a maintenance station, and the valve C9 enables the pressure part 6 of the pressure cylinder to operate, the piston rod moves upwards and downwards in the working stroke, namely the upper die 2 is driven to move upwards and downwards between the station to be hot sealed and the station to be hot; when the upper die 2 needs to stand by after completing the heat sealing operation, the valve 8B is closed, and the valve 7A and the valve 9C control the pre-pressing part 5 and the pressurizing part 6 to drive the upper die 2 to move up to the maintenance station.
Claims (4)
1. The utility model provides a heat-seal mechanism, includes the frame, goes up mould and lower mould, it is connected with the lift part that drives its lift to go up the mould, its characterized in that the stroke that the lift part drive was gone up and down is divided into working stroke and maintenance stroke, the lift part is including pressure cylinder and control valve, pressure cylinder is including pre-compaction part and pressure boost part, the control valve is including the control pre-compaction part admit air with carminative A number valve, the control pressure boost part admit air with carminative C number valve and prevent that the pre-compaction part from admitting air and exhausting the valve of B number of backward flow.
