Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model provides a sanitary bag sealing device, comprising:

[0024] The cam clamping device comprises a protective plate, and two parallel side mounting plates 2 are threadedly mounted on the bottom of the protective plate; through grooves are dug in the mounting plates 2 on both sides, and shaft fixing plates 3 are fixedly mounted in the through grooves; an outer shaft 4, an inner shaft 5 and a limit shaft are mounted on the two shaft fixing plates 3; the limit shaft is arranged close to the outer shaft 4, and two clamping cams 19 are mounted on the limit shaft, and the clamping cams 19 are configured to contact with the outer shaft 4; the two clamping cams 19 are fixedly connected to the clamping handle 6, and the clamping handle 6 is rotatably mounted on the limit shaft;

[0025] The two ends of the outer shaft 4 and the inner shaft 5 pass through the two shaft fixing plates 3 respectively, and are respectively installed with an outer heater bracket 15 and an inner heater bracket 16; the outer sealing heater 25 and the inner sealing heater 24 are respectively fixedly installed on the opposite sides of the bottom ends of the outer heater bracket 15 and the inner heater bracket 16;

[0026] The driving mechanism is installed on one side of the inner heater bracket 16; the driving mechanism is configured to realize the swing of the inner heater bracket 16; the outer shaft 4 and the inner shaft 5 are connected by a gear set.

[0027] The protective plate includes a top plate 1, and a sealing bracket, two symmetrically arranged left guard plates 11 and right guard plates 10 are fixedly installed on the bottom surface of the top plate 1; the left guard plates 11 and the right guard plates 10 are arranged parallel to the mounting plates 2 on both sides; the sealing bracket is arranged between the left guard plates 11 and the right guard plates 10 and the mounting plates 2 on both sides, and the sealing bracket is threadedly installed on the bottom surface of the top plate 1.

[0028] A hanging card 7 is also installed on one side of the external heater bracket 15.

[0029] The gear set includes an outer gear 20 and an anti-error tooth outer plate 8 installed at both ends of the outer shaft 4, and an inner gear 18 and an anti-error tooth inner plate 9 installed at both ends of the inner shaft 5; partial tooth shapes are formed on the anti-error tooth outer plate 8 and the anti-error tooth inner plate 9, and the outer gear 20 and the inner gear 18 are meshed.

[0030] A spring groove is provided in the side mounting plate 2 , a spring 21 is provided in the spring groove, and the spring 21 is provided between the outer shaft 4 and the inner shaft 5 .

[0031] The driving mechanism includes a fixing seat 13 fixedly mounted on one side of the inner heater bracket 16 , on which a cylinder 14 is mounted via a spherical bearing 23 ; a cylinder rod 22 of the cylinder 14 is drivingly connected to the pendulum block 12 .

[0032] A rotating handle 17 is also rotatably mounted on the outer heater bracket 15 .

[0033] In one embodiment of the utility model, the external heater bracket 15 can be pulled up by rotating the handle 17 and hung in the hanging card 7 arranged on the external heater bracket 15; the outer shaft 4 is fixed to the side mounting plate 2 through the shaft fixing plate 3, and the shaft fixing plate 3 is also provided with a spring 21. When the clamping handle 6 opens the outer shaft 4 away from the inner shaft 5 by rotating the clamping cam 19, the outer gear 20 is no longer engaged with the inner gear 18.

[0034] In one embodiment of the utility model, when the sealing device is working, the driving swing block 12 is driven by the outer end indexer to swing a certain angle, and the cylinder 14 and the joint bearing 23 perform displacement action, thereby driving the inner heater bracket 16 to swing around the inner shaft 5 as the center, thereby driving the inner sealing heater 24 to move toward the packaging bag opening;

When the outer sealing heater 25 with a certain temperature is closed with the inner sealing heater 24 with a certain temperature, the bag opening is sealed completely.

[0036] Furthermore, when the sealing heater needs to be cleaned, the clamping handle 6 is pulled up to drive the clamping cam 19 connected thereto to rotate. At this time, it is ejected by the spring 21, and the outer gear 20 and the inner gear 18 are no longer engaged. Then the outer heater bracket 15 can be flipped up through the rotating handle 17 fixed thereto, and can be hung on the hanging card 7. At this time, there is enough space for cleaning and maintenance. When production is required, just reverse the above steps; when the packaging bag does not need to be sealed, a signal can be sent to the solenoid valve controlling the cylinder to retract the cylinder rod 22 of the cylinder 14, so that the outer sealing heater 25 and the inner sealing heater 24 are no longer closed, and the packaging bag is discharged therefrom, thereby realizing the non-feeding discharge function.
