Description

Technical Field

[0001] This utility model relates to a sealing and cutting machine, and more particularly to a heat dissipation mechanism of a sealing and cutting device for a food sealing and cutting machine. Background Technology

[0002] Sealing and cutting machines are fully automatic, unmanned packaging machines widely used in mass production packaging lines. They offer high efficiency, automatically feeding and punching film, automatically sealing and cutting, and automatically rolling up waste material. Only manual adjustment of the film guiding system and the feeding conveyor platform is required, making them suitable for products of varying widths and heights. They can be used in conjunction with automated packaging lines and are the preferred choice for sealing and heat-shrink packaging.

[0003] The sealing and cutting device of a sealing and cutting machine mainly consists of a mounting frame, a hot cutting blade, and a drive assembly for driving the hot cutting blade to move up and down. The hot cutting blade contains a heating wire, which heats the blade to achieve the melting and cutting operation of the packaging film during transport. During long-term operation of the sealing and cutting machine, the heat generated by the hot cutting blade is conducted outwards to the drive assembly through connected components, causing the drive assembly to be in a high-temperature environment for extended periods, which undoubtedly has an adverse impact on its service life. Although existing sealing and cutting devices are equipped with simple heat dissipation hole structures, the heat dissipation efficiency of these holes is largely limited by the ambient temperature of the factory. Once the ambient temperature rises, the heat dissipation effect will decrease significantly. Therefore, this improved solution was developed. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation mechanism for the sealing and cutting device of a food sealing and cutting machine. This heat dissipation mechanism can effectively reduce the heat transferred from the hot cutting blade to the drive component, thereby improving the service life of the drive component.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat dissipation mechanism for a food sealing and cutting machine, comprising a mounting frame, a hot cutting blade, and a drive assembly mounted on the mounting frame. The drive assembly and the hot cutting blade are connected by a connector. A heat dissipation area is formed within the connector. A heat dissipation component that moves with the connector is rotatably disposed within the heat dissipation area. A linkage component is connected to the heat dissipation component. The connector drives the heat dissipation component to move and the linkage component drives the heat dissipation component to rotate.

[0006] By adopting the above technical solution, the heat from the hot cutting blade is conducted to the connector and concentrated in the heat dissipation area. This heat dissipation area exchanges heat with the air, achieving the first stage of cooling. The drive assembly drives the connector and causes the heat dissipation component to move synchronously. The moving heat dissipation component, under the action of the linkage assembly, forms a linkage, causing it to rotate. This rotation further accelerates the heat exchange efficiency, thereby achieving more effective cooling of the connector and reducing heat conduction to the drive assembly. This structural design effectively reduces the heat transferred from the hot cutting blade to the drive assembly, thus extending the service life of the drive assembly.

[0007] Further configuration: the linkage component connects the heat sink and the mounting bracket.

[0008] By adopting the above technical solution, this configuration structure is used to create relative motion between the two linked components, thereby achieving the purpose of linkage drive.

[0009] The connector is further configured such that: the connector includes a connecting frame and a left connecting side plate and a right connecting side plate disposed on the connecting frame; the left connecting side plate and the right connecting side plate are spaced apart and each is provided with heat dissipation holes; and the heat dissipation area is located between the left connecting side plate and the right connecting side plate.

[0010] By adopting the above technical solution, this configuration not only achieves a stable connection between the drive component and the hot cutting blade, but also helps the airflow pass through the connector to more efficiently remove heat from the heat dissipation area, and also helps the heat dissipation component to dissipate heat efficiently.

[0011] The linkage component is further configured such that: the linkage assembly includes a linkage rack disposed on the mounting bracket and a linkage gear disposed on the heat sink and moving with the heat sink, wherein the movement path formed by the linkage gear moving with the heat sink is parallel to the length direction of the linkage rack and can mesh with the linkage rack.

[0012] By adopting the above technical solution, the drive component drives the connector, heat sink and linkage gear to move synchronously. During the movement, the linkage gear passes through the linkage rack and meshes with the linkage rack, thereby driving the linkage gear and heat sink to rotate, so as to achieve the heat dissipation effect.

[0013] The heat sink is further configured such that it is rotatably mounted on the connector via a rotating shaft, and a one-way bearing is installed between the rotating shaft and the linkage gear.

[0014] By adopting the above technical solution, the one-way bearing enables the linkage gear to rotate in one direction during reciprocating motion through one-way linkage, so that the heat sink can only rotate continuously in one direction to generate greater airflow and achieve better heat dissipation.

[0015] A further configuration is provided: an adjustment component is provided between the linkage rack and the mounting bracket for adjusting the reciprocating motion of the linkage rack toward the linkage gear side.

[0016] By adopting the above technical solution, since the positions of the linkage gears are different due to different models of sealing and cutting devices, the position of the linkage rack is controlled by the set adjustment component to ensure that it meshes with the linkage gears in different positions, thereby improving the versatility of the setting structure.

[0017] The configuration is further defined as follows: the linkage rack is slidably disposed on the mounting frame, and the adjustment component includes an adjustment screw disposed on the linkage rack and passing through the mounting frame, and a locking nut threadedly connected to the adjustment screw and located on both sides of the mounting frame.

[0018] By adopting the above technical solution, after the adjusting screw is adjusted to the appropriate position along with the linkage rack, the movement of the linkage rack is restricted by tightening the two locking nuts, thereby achieving the purpose of convenient adjustment.

[0019] In summary, this utility model has the following beneficial effects: it can effectively reduce the heat transferred from the hot cutting blade to the drive assembly, thereby improving the service life of the drive assembly. Attached Figure Description
