For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figures 1 to 4 As shown, the sealing device 100 for making integrated packaging composite aluminum foil bags of the utility model includes a conveyor belt 1 for conveying aluminum foil bags, a limiter 2 arranged on the conveyor belt 1, a sealing assembly 3 arranged above the conveyor belt 1 for sealing the aluminum foil bags, and a conveying frame 4 arranged on both sides of the conveyor belt 1.

[0025] The conveying frame 4 serves to support the conveyor belt 1 .

[0026] The limiting member 2 includes a lower limiting plate 21 disposed below and close to the transmission, an upper limiting plate 22 disposed above the lower limiting plate 21 , and a support rod 23 connected between the upper limiting plate 22 and the lower limiting plate 21 .

[0027] The number of the lower limiting plates 21 and the upper limiting plates 22 are both two and are arranged on both sides of the aluminum foil bag to limit the upper and lower sides of the aluminum foil bag so that the aluminum foil bag remains in an upright state.

[0028] The lower limit plate 21 is fixed on the conveying frame 4 and extends upward from the conveying frame 4. The lower limit plate 21 has the effect of limiting the lower end 336 of the aluminum foil bag.

[0029] The upper limit plate 22 includes a first limit plate 221 located below the sealing assembly 3 and a second limit plate 222 away from the sealing assembly 3 , and the distance between the first limit plates 221 on both sides is smaller than the distance between the second limit plates 222 on both sides.

[0030] Along the conveying direction of the conveyor belt 1, the first limiting plate 221 is arranged behind the second limiting plate 222. That is, the aluminum foil bag first passes through the second limiting plate 222 and then moves to the first limiting plate 221. A transition plate 223 is arranged between the first limiting plate 221 and the second limiting plate 222.

[0031] The first limiting plates 221 on both sides are arranged in parallel. The second limiting plates 222 have the effect of limiting the upper end 335 of the aluminum foil bag, and the first limiting plates 221 are used to squeeze the upper bag opening of the aluminum foil bag to make it relatively closed, which is convenient for subsequent clamping and heat sealing.

[0032] The second limit plate 222 is arranged directly above the lower limit plate 21, and the support rod 23 includes a first rod body 231 for connecting the first limit plate 221 and the lower limit plate 21, and a second rod body 232 for connecting the second limit plate 222 and the lower limit plate 21, the second rod body 232 extends in the vertical direction, and the first rod body 231 is bent.

[0033] The sealing assembly 3 includes a bracket 31 extending upward from the conveying frame 4 , a driving member 32 disposed on the bracket 31 , and a sealing member 33 driven by the driving member 32 to seal the aluminum foil bag. The sealing member 33 is disposed above the first limiting plate 221 .

[0034] The driving member 32 includes a hydraulic cylinder 321 and a piston rod 322 . The hydraulic cylinder 321 is fixed on the bracket 31 , and the piston rod 322 extends downward from the bottom of the hydraulic cylinder 321 .

[0035] The sealing member 33 includes a mounting block 331 fixed on the bracket 31, clamping rods 332 arranged on both sides of the mounting block 331, a hot pressing plate 333 arranged at the bottom of the clamping rod 332, and a push-pull rod 334 connecting the piston rod 322 and the clamping rod 332. The piston rod 322 passes through the mounting block 331 in the vertical direction, and the push-pull rod 334 is hinged to the piston rod 322.

[0036] The clamping rod 332 is divided into an upper end 335 and a lower end 336 which are bent and connected. The upper end 335 is hinged to the mounting block 331, and the lower end 336 is fixedly connected to the hot pressing plate 333. The end of the push-pull rod 334 away from the piston rod 322 is hinged to the connection between the upper end 335 and the lower end 336.

[0037] When the aluminum foil bag is conveyed between the two heat pressing plates 333, the conveyor belt 1 is paused and the hydraulic cylinder 321 is started to drive the piston rod 322 to retract upward, pull up one end of the push-pull rod 334, and the other end of the push-pull rod 334 drives the clamping rod 332 to close inward, and the bottom end of the clamping rod 332 drives the two heat pressing plates 333 to close and clamp the bag opening of the aluminum foil bag. In the process of maintaining the clamping, the high temperature of the inner side of the heat pressing plate 333 is used to fuse the bag opening of the aluminum foil together to achieve heat sealing; after the heat sealing is completed, the hydraulic rod drives the piston rod 322 to press down, and the clamping rod 332 is pushed outward by the push-pull rod 334, thereby driving the two heat pressing plates 333 to separate, completing the reset and waiting for the next heat sealing operation.

[0038] The working process of the sealing device 100 for making integrated packaging composite aluminum foil bags is as follows: the lower limit plate 21 limits the bottom of the aluminum foil bag being conveyed, and the upper limit plate 22 limits the top of the composite aluminum foil bag. When the composite aluminum foil bag is about to be conveyed to the position of the hot pressing plate 333, the first limit plate 221 is narrowed inwardly, squeezing the upper bag mouth of the aluminum foil bag to close it. When the composite aluminum foil bag is conveyed between the two hot pressing plates 333, the conveyor belt 1 is paused and the hydraulic cylinder 321 is started, and the piston rod 322 contracts upward, and the two hot pressing plates 333 are closed and clamped by the push-pull rod 334 and the clamping rod 332. In the process of maintaining the clamping, the high temperature of the inner side of the hot pressing plate 333 is used to fuse the aluminum foil bag mouth together to achieve heat sealing. At this time, the sealing device for making integrated packaging composite aluminum foil bags is in working state; then the conveyor belt 1 is started to send the sealed aluminum foil bag away, and the next aluminum foil bag to be sealed is moved to the position of the hot pressing plate 333, and the above process is repeated.

[0039] The sealing device 100 for making an integrated packaging composite aluminum foil bag of the utility model limits the bottom and the top of the aluminum foil bag by setting a limiter 2, so that the aluminum foil bag remains upright and the contents are not easily spilled. By setting a first limiter plate 221 with a shorter interval, the buckles of the aluminum foil bag are closed together, the bag opening is not easily misplaced, and a good heat sealing effect is guaranteed.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
