[0008] The utility model provides a detachable device for the vacuum nozzle of a heat sealing machine, which replaces the cumbersome steps of stopping the machine and removing the fixed structure in order to clean waste glue from the old vacuum nozzle. It only requires unfastening the clamp and replacing it with a new clean vacuum nozzle, thereby improving work efficiency and reducing labor costs and safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0010] Figure 1 It is a structural schematic diagram of the heat sealing machine of the utility model;

[0011] Figure 2 It is a schematic diagram of the structure of the clamp.

[0012] In the figure: an upper rubber storage cover 1, a clamp 2, a semicircular groove 21, a connecting block 22, a hinge 23, a sealing gasket 24, an exhaust nozzle 3, an exhaust fan hose 4, a lower rubber storage cover 5, a lifting cylinder 6, and a pressure sensor 7. DETAILED DESCRIPTION

[0013] A detachable device for exhaust nozzle of a heat sealing machine comprises an upper rubber storage cover 1 and a lower rubber storage cover 5. The upper rubber storage cover 1 and the lower rubber storage cover 5 are fixed together by a clamp 2 to form a rubber storage chamber. The top of the upper rubber storage cover 1 is fixedly connected to the telescopic part of the lifting cylinder 6. The upper rubber storage cover 1 is provided with an exhaust fan hose 4, and the lower end of the lower rubber storage cover 5 is provided with an exhaust nozzle 3.

[0014] like Figure 1 As shown in the figure, the glue storage chamber is divided into two upper and lower glue storage covers which are combined by a clamp 2. When the exhaust effect is reduced due to residual waste glue in the glue storage chamber, the upper and lower parts can be separated by opening the clamp 2, so that the lower glue storage cover 5 and the exhaust nozzle 3 at the lower part can be cleared or replaced, and the upper glue storage cover 1 can be cleared, so as to quickly realize the clearing or replacement operation.

[0015] The clamp 2 is formed by two semicircular grooves 21 hingedly connected by hinges 23 at the ends. A connecting block 22 is provided at the other end of the two semicircular grooves 21. The connecting block 22 is used to fix the two semicircular grooves 21 together.

[0016] like Figure 1 and 2 As shown in FIG, after the two semicircular embedding grooves 21 are hingedly fixed, the end T-shaped parts of the upper glue storage cover 1 and the lower glue storage cover 5 can be embedded in the grooves and fixed to form a complete glue storage chamber.

[0017] The semicircular groove 21 is covered with a sealing gasket 24 .

[0018] The sealing gasket 24 is used to achieve sealing between the upper and lower rubber storage covers.

[0019] The upper glue storage cover 1 is provided with a pressure sensor 7, and the pressure sensor 7 is connected to the control system of the heat sealing machine.

[0020] like Figure 1 As shown in the figure, the pressure sensor 7 is used to detect the suction pressure. According to the Bernoulli principle, when the suction pressure is constant, when serious colloid residue appears in the glue storage chamber, the fluid cross-section becomes smaller, the flow rate increases, and the pressure becomes smaller. It is possible to determine whether residual glue occurs by detecting the pressure in the glue storage chamber, so as to remind the control system to perform replacement or clearing operations.

[0021] The working process of the heat sealing machine is as follows:

[0022] During the operation of the heat sealing machine, after the automatic control program of the heat sealing machine is started, the photoelectric sensing signal of the heat sealing machine photoelectric sensing box in place is given to the PLC of the heat sealing machine as an input signal, and the PLC then sends an output signal through the program. When the vacuum cylinder descends to the vacuum position, the magnetic photoelectric sensing signal that the cylinder has descended into place is given, and an input signal is given to the PLC, which then sends an output signal. The vacuum fan starts to run, and the airflow passes through the vacuum nozzle-glue storage chamber-vacuum hose to vacuum the residual gas in the film, changing the previous need to manually remove the residual gas in the film.
