Description

Technical Field

[0001] This utility model relates to automatic packaging machines, and in particular to a cooling device for a sealing machine that uses air blowing for cooling. Background Technology

[0002] Existing sealing machines use a set of cooling belts to press the sealing position of the packaging bag and cool it while conveying it. A fan is set at the end of the pressing belt for rapid cooling. The cooling structure is relatively long, which makes the sealing machine using this cooling structure relatively long. In particular, multi-function sealing machines integrate folding and sewing and heat sealing and cooling functions, resulting in an excessively long overall length, which is not conducive to production layout. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a cooling device for a sealing machine with air blowing cooling. The device is designed with a backing plate and a baffle to form a cooling space. The air blowing port sends airflow into the cooling space. The airflow velocity at the air blowing port is fast, which has a rapid cooling effect. The airflow velocity away from the air blowing port is slow, which has a pre-cooling effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the air-cooled sealing machine cooling device includes a backing plate and a baffle plate. The backing plate has a backing surface, the baffle plate has a blocking surface, and the blocking surface is provided with an air blowing port. A cooling space is formed between the backing surface and the blocking surface. The air blowing port divides the cooling space into a pre-cooling area and a rapid cooling area.

[0005] In this solution, the air outlet blows air onto the contact surface. The airflow is blocked by the obstruction surface and disperses within the cooling space. The airflow speed in the fast cooling zone corresponding to the air outlet is fast, and the cooling effect is strong. The airflow speed in the pre-cooling zone is slow, and the cooling is slow. Pre-cooling avoids wrinkles caused by rapid cooling and shrinkage at the sealing point. Compared with the cooling method of cooling belt, it effectively shortens the length of the cooling mechanism.

[0006] Preferably, it also includes a pressure roller assembly, wherein the back plate and the baffle are both arranged in the front-back direction, the baffle and the back plate extend forward with an extension section, and the pressure roller assembly is located below the extension section.

[0007] In this scheme, the pressure roller assembly presses the sealing position of the packaging bag to ensure a firm seal, while the extension section corresponds to the pre-cooling area, and the airflow that escapes to the pressure roller assembly provides initial cooling to the sealing position of the packaging bag.

[0008] Preferably, the area between the backing plate and the baffle is defined as the inner side, and the front end of the extension section extends outward to form an open bag inlet.

[0009] In this design, the open inlet facilitates the heat-sealed packaging bag entering between the backing plate and the baffle.

[0010] Preferably, it also includes a fan, which cools the air inlet or the fan according to the shrinkage characteristics of the packaging bag material.

[0011] In this solution, air cooling or wind cooling is adopted based on the shrinkage characteristics of the packaging bag material.

[0012] Preferably, the fan is connected to the mounting plate, and the mounting plate is mounted on the backing plate and the baffle.

[0013] In this design, the backplate and baffle together support the fan.

[0014] Preferably, the air inlet is through which the air blowing pipe passes, the air blowing pipe has an air outlet, and the air blowing pipe is connected to an air source.

[0015] In this design, the air blowing pipe extends into the cooling space, and the air outlet is close to the sealing position of the packaging bag, resulting in a good cooling effect.

[0016] Preferably, the air inlet is connected to an air source via an air delivery pipe.

[0017] In this scheme, the air source delivers airflow into the cooling space through the air blowing port.

[0018] Preferably, the air inlet is larger than the cross-section of the air pipe.

[0019] In this design, the air blowing pipe can be moved and adjusted after being inserted into the air blowing port to ensure that the air outlet is aligned with the sealing position and cooled properly.

[0020] The beneficial effects of this invention are as follows: the air outlet directs airflow onto the contact surface, where the airflow is blocked by the obstruction surface and disperses within the cooling space. The rapid cooling zone corresponding to the air outlet has a high airflow velocity and a strong cooling effect, while the pre-cooling zone has a slow airflow velocity and a slower cooling effect. Pre-cooling avoids wrinkles caused by rapid cooling and shrinkage at the sealing point. Compared with the cooling belt method, this invention effectively shortens the length of the cooling mechanism. Therefore, this invention has substantial features and progress compared with the prior art. Attached Figure Description

[0028] See appendix Figure 1-2 In this embodiment, a sealing machine cooling device for air blowing cooling includes a backing plate 1 and a baffle plate 2. The backing plate 1 has a backing surface, and the baffle plate 2 has a blocking surface. The blocking surface is provided with an air blowing port 3. A cooling space is formed between the backing surface and the blocking surface. The air blowing port 3 divides the cooling space into a pre-cooling area and a rapid cooling area.

[0029] It also includes a pressure roller assembly 4. The back plate 1 and the baffle 2 are both arranged in the front-back direction. The baffle 2 and the back plate 1 extend forward with an extension section 5. The pressure roller assembly 4 is located below the extension section 5, defining the area between the back plate 1 and the baffle 2 as the inner side. The front end of the extension section 5 unfolds outward to form an open bag inlet.

[0030] It also includes a fan 6, which cools the packaging bag material by means of the air outlet 3 or the fan 6. The fan 6 is connected to the mounting plate 7, which is mounted on the back plate 1 and the baffle 2.

[0031] In this embodiment, the packaging bag is clamped and fed into the space between the inlet plate 1 and the baffle plate 2. After being pressed by the pressure roller group 4, it continues to be conveyed. For packaging bag materials that shrink quickly, air cooling is used. The airflow blown in by the air blowing pipe 8 is dispersed to the pressure roller group 4 for pre-cooling. After the packaging bag reaches the air blowing port 3 at the sealing position, it is rapidly cooled. For packaging bag materials that shrink slowly, air cooling is used. The fan 6 has a large air volume, and the packaging bag sealing position is rapidly cooled throughout the process.

[0032] The pressure roller surface can be patterned, and the embossing makes the sealing position beautiful; the back plate 17 and the baffle 28 have good thermal conductivity. When the sealing position of the packaging bag passes through the air blowing port 3, the airflow will press the packaging bag onto the back plate 1, and the sealing position will be in contact with the backing surface, and can also directly contact heat dissipation; the air blowing port 3 can be connected to the air supply pipe, or the air blowing pipe 8 can pass through the air blowing port 3.
