Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically a heat-sealing component for aluminum foil bags. Background Technology

[0002] Aluminum foil bags are one of the most commonly used aluminum foil bag structures in the packaging industry. The production and sealing of aluminum foil bags often employ heat sealing devices.

[0003] Most existing heat sealing devices, as described in the text of Chinese Patent Publication No. CN112093157B entitled "A Heat Sealing Device for Aluminum Foil Bags", employ a clamping part to clamp the aluminum foil bag, and then use a cylinder to drive the heat sealing head to press the aluminum foil bag to achieve the heat sealing operation.

[0004] However, in practice, due to the high thermal conductivity of aluminum foil, the heat generated during the heat sealing process quickly transfers to the non-heat-sealed areas, causing them to stick together due to the increased temperature. This not only results in the aluminum foil bag failing to meet appearance requirements but also reduces the internal space, hindering subsequent filling. Therefore, this issue urgently needs to be addressed. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a heat-sealing component for aluminum foil bags, which can keep the heat-sealed area constant during the heat-sealing process of aluminum foil bags, prevent adhesion in non-heat-sealed areas, and realize the standardized production and sealing of aluminum foil bag products.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat-sealing assembly for aluminum foil bags includes a mounting frame and a heat-sealing head on the mounting frame that is driven to rise and fall by a hydraulic cylinder. It also includes a liquid cooling plate that can move up and down and is arranged next to the heat-sealing head. In a top view, the two ends of the cooling zone are flush with the two ends of the heating zone or protrude to the outer side of the two ends of the heating zone. When the heat-sealing head slides down to the heat-sealing state that presses the aluminum foil bag, the cooling zone of the liquid cooling plate is parallel to the heating zone of the heat-sealing head and the adjacent sides are closely attached. The lower surfaces of the cooling zone and the heating zone are flush and together press the aluminum foil bag.

[0008] As a further embodiment of this utility model: the liquid cooling plate is movably mounted on the heat sealing head, and in the standby state where the heat sealing head slides upward and moves away from the aluminum foil bag, the liquid cooling plate is arranged separately from the heat sealing head.

[0009] As a further improvement of this utility model: the liquid cooling plate can slide relative to each other in the vertical direction, and in the standby state, the heat sealing head and the liquid cooling plate are arranged separately in the vertical direction.

[0010] As a further embodiment of this utility model: a connecting plate is fixed on the heat sealing head, and a vertical guide rod that extends upward through the connecting plate is fixed on the liquid cooling plate, with a stop block connected to the top of the vertical guide rod; when the heat sealing head slides upward to the standby state in the heat sealing state, the liquid cooling plate slides vertically downward relative to the connecting plate to form the separated arrangement, and the liquid cooling plate is driven to move upward under the contact of the upper part of the connecting plate and the stop block.

[0011] As a further embodiment of this utility model: the liquid cooling plate is driven by a first linear power mechanism installed on the heat sealing head, and in the standby state, the liquid cooling plate is driven to separate from the heat sealing head in the vertical direction.

[0012] As a further improvement of this utility model: the liquid cooling plate can slide relative to each other in the horizontal direction, and in the standby state, the heat sealing head and the liquid cooling plate are arranged separately in the horizontal direction.

[0013] As a further embodiment of this utility model: a horizontally arranged guide rod is fixed on the heat sealing head, and the liquid cooling plate is slidably fitted on the horizontal guide rod through a sliding sleeve. The lower surfaces of the cooling zone and the heating zone are always flush. In the standby state, the liquid cooling plate is driven by a compression spring and is arranged separately from the heat sealing head in the horizontal direction. A wedge block is fixed on the liquid cooling plate, and a drive rod is fixed on the mounting bracket. In the heat sealing state, the wedge block and the drive rod are wedge-shaped to form a tight fit between the cooling zone and the heating zone.

[0014] As a further improvement of this utility model: the liquid cooling plate is driven by a second linear power mechanism installed on the heat sealing head, and in the standby state, the liquid cooling plate is driven to be separated from the heat sealing head in the horizontal direction.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By arranging the cooling zone of the liquid cooling plate and the heating zone of the heat sealing head in close contact and with their lower surfaces flush, the cooling zone can actively cool the non-heat-sealed areas of the aluminum foil bag during heat sealing, avoiding adhesion of non-target areas caused by heat conduction, ensuring clear boundaries of the heat-sealed area, and improving product consistency.

[0017] 2. In standby mode, the liquid cooling plate and the heat sealing head automatically separate, reducing heat exchange between them. This reduces energy loss during standby and ensures that the heat sealing head can quickly reach the optimal operating temperature and that the liquid cooling plate achieves the best cooling effect during operation.

[0018] 3. This application provides two embodiments of vertical sliding or horizontal sliding separation arrangement, which can be flexibly selected according to the installation space to adapt to different equipment layout requirements.

[0019] Furthermore, in the vertical sliding scheme, the liquid cooling plate uses gravity or a simple guiding structure to achieve linkage with the heat sealing head, while in the horizontal sliding scheme, the liquid cooling plate achieves linkage with the heat sealing head through the wedge engagement between the compression spring, wedge block, and drive rod. Neither of these schemes requires an additional power source to drive the liquid cooling plate, effectively reducing the operating cost of the components. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0028] The specific structure of this utility model is as follows: Figure 1-5As shown, its main structure includes a mounting frame 10 and a heat sealing head 30 on the mounting frame 10 that is driven to rise and fall by a hydraulic cylinder 20, and also includes a liquid cooling plate 40 that can be raised and lowered and arranged on the side of the heat sealing head 30. Specifically, from a top-down perspective, the two ends of the cooling zone 41 are flush with or protrude to the outer sides of the heating zone 31. When the heat sealing head 30 slides down to press the aluminum foil bag into a heat-sealed state, the cooling zone 41 of the liquid cooling plate 40 is parallel to the heating zone 31 of the heat sealing head 30 and the adjacent sides are closely attached. This allows the cooling zone 41 to be flush with the lower surface of the heating zone 31 and press the aluminum foil bag together when the liquid cooling plate 40 slides down. The heating zone 31 presses the heat-sealed area of ​​the aluminum foil bag, while the cooling zone 41 presses the non-heat-sealed area of ​​the aluminum foil bag. The cooling zone 41 cools the non-heat-sealed area of ​​the aluminum foil bag, effectively preventing the temperature of the non-heat-sealed area from rising and sticking due to heat conduction during the heat sealing process. This ensures that the heat-sealed area of ​​the aluminum foil bag remains constant during the heat sealing process, thus achieving standardized production and sealing of aluminum foil bag products.

[0029] Based on the above, such as Figure 1 and Figure 4 As shown, the liquid cooling plate 40 is movably mounted on the heat sealing head 30, and in the standby state where the heat sealing head 30 slides upward and away from the aluminum foil bag, the liquid cooling plate 40 is arranged separately from the heat sealing head 30. This ensures that the temperature difference between the heat sealing head 30 and the liquid cooling plate 40 does not affect each other in the standby state, which not only reduces energy consumption in the standby state, but also ensures that the heat sealing head 30 has a good heat sealing effect and the liquid cooling plate 40 has a good cooling effect when switching from the standby state to the heat sealing state.

[0030] Based on the above, this application provides two implementation methods for the separate arrangement of the heat-sealing head 30 and the liquid-cooling plate 40:

[0031] Example 1, such as Figure 1 and Figure 2 As shown.

[0032] The liquid cooling plate 40 can slide relative to each other in the vertical direction, and in the standby state, the heat sealing head 30 and the liquid cooling plate 40 are arranged separately in the vertical direction. This embodiment is suitable for heat sealing devices with sufficient installation space in the vertical direction.

[0033] Specifically, such as Figure 1As shown, a connecting plate 33 is fixed on the heat-sealing head 30, and a vertical guide rod 44 extending upward through the connecting plate 33 is fixed on the liquid-cooling plate 40. A stop block 45 is connected to the top of the vertical guide rod 44, allowing the liquid-cooling plate 40 to slide stably relative to the heat-sealing head 30 in the vertical direction. When the heat-sealing head 30 slides upward to the standby state in the heat-sealing state, the liquid-cooling plate 40 slides vertically downward relative to the connecting plate 33 to form a separated arrangement. Under the contact of the upper part of the connecting plate 33 and the stop block 45, the liquid-cooling plate 40 is driven to move upward, thus eliminating the need for an additional power source to drive the liquid-cooling plate 40 to move up and down. In this embodiment, in the heat-sealing state, the liquid-cooling plate 40 mainly relies on its own gravity to press the aluminum foil bag. Of course, if it is necessary to reduce the gravity of the liquid-cooling plate 40, the connecting plate 33 can be used to press the liquid-cooling plate 40 in the heat-sealing state, or a spring can be set to drive the liquid-cooling plate 40 to generate a downward elastic force.

[0034] Of course, the lifting and lowering movement of the liquid cooling plate 40 can also be achieved using other additional power sources. For example, the liquid cooling plate 40 can be driven by a first linear motion power mechanism mounted on the heat sealing head 30, and in standby mode, the liquid cooling plate 40 can be driven to separate from the heat sealing head 30 in the vertical direction. The first linear motion power mechanism can be a cylinder or a lead screw-slider mechanism commonly used in the prior art, as long as it can drive the liquid cooling plate 40 to produce lifting and lowering movements.

[0035] Example 2, as Figure 3-5 As shown.

[0036] The liquid cooling plate 40 can slide relative to each other in the horizontal direction, and in the standby state, the heat sealing head 30 and the liquid cooling plate 40 are arranged separately in the horizontal direction. This embodiment is suitable for heat sealing devices with sufficient installation space in the horizontal direction.

[0037] Specifically, such as Figure 3 and Figure 4 As shown, a horizontally arranged guide rod 32 is fixed on the heat sealing head 30. The liquid cooling plate 40 is slidably fitted onto the horizontal guide rod 32 via a sliding sleeve 42. The lower surfaces of the cooling zone 41 and the heating zone 31 are always flush, so that when switching from the standby state to the heat sealing state, the cooling zone 41 only needs to slide horizontally and fit against the heating zone 31. In the standby state, the liquid cooling plate 40 is driven by the compression spring 50 and is arranged horizontally separate from the heat sealing head 30. A wedge block 43 is fixed on the liquid cooling plate 40, and a drive rod 11 is fixed on the mounting bracket 10. In the heat sealing state, the wedge block 43 and the drive rod 11 wedge together obliquely, making the cooling zone 41 and the heating zone 31 fit tightly together, thus eliminating the need for an additional power source to drive the liquid cooling plate 40 to slide horizontally. In this embodiment, in the heat sealing state, both the liquid cooling plate 40 and the heat sealing head 30 rely on the driving force of the hydraulic cylinder 20 to press the aluminum foil bag.

[0038] Of course, the horizontal movement of the liquid cooling plate 40 can also be achieved using other additional power sources. The liquid cooling plate 40 is driven by a second linear motion power mechanism mounted on the heat sealing head 30, and in standby mode, it drives the liquid cooling plate 40 to be horizontally separated from the heat sealing head 30. The second linear motion power mechanism can be a cylinder or a lead screw-slider mechanism commonly used in the prior art, as long as it can drive the liquid cooling plate 40 to produce horizontal movement.

[0039] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
