[0003] A swing-arm cover vacuum packaging machine usually requires a plurality of swing arms to be rotatably arranged on the swing cover, and the rotation of the plurality of swing arms drives the swing cover to move, so as to achieve the effect of packaging the product. The rotation of the swing arm of the swing-arm cover packaging machine in the prior art is usually driven by a motor, and a motor is separately arranged on each swing arm to drive the transmission. When the swing cover swings, it is necessary to ensure that the swing amplitude of each swing arm is consistent. When the swing arms are driven to rotate by multiple motors, if the motors are not synchronized, the motors are easily damaged, which affects the service life of the packaging machine. Therefore, a packaging machine swing arm is designed to solve the above problem. Utility Model Content

[0024] Example:

[0025] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a packaging machine swing arm, including a packaging table 1, a hot pressing plate 2, a pin shaft 3, a swing arm 4, a transmission shaft 5 and a motor 6. The transmission shaft 5 is rotatably arranged on the upper left and right sides of the outside of the packaging table 1, the swing arm 4 is fixedly arranged on the outer end of the transmission shaft 5, the hot pressing plate 2 is rotatably arranged on the top of the swing arm 4 through the pin shaft 3, a driven sprocket 501 is fixedly arranged at the center of the transmission shaft 5, a motor 6 is fixedly arranged at the lower inner side of the packaging table 1, a driving sprocket 601 is fixedly arranged at the output end of the motor 6, and a transmission chain 7 is sleeved between the driving sprocket 601 and the two driven sprockets 501.

[0026] By providing a driving sprocket 601, a driven sprocket 501 and a transmission chain 7, when packaging the product, the packaging bag containing the product is placed on the packaging table 1, and then the motor 6 is turned on. The motor 6 drives the driving sprocket 601 to rotate, and the driving sprocket 601 drives the two driven sprockets 501 to rotate through the transmission chain 7, so that the two transmission shafts 5 rotate, and the swing arm 4 is driven to rotate, so that the hot pressing plate 2 swings to the top of the product to be packaged, so as to achieve the packaging effect. The swing of multiple swing arms 4 can be realized by rotating a single motor 6, and there will be no problem of motor asynchrony, thereby ensuring the service life.

[0027] In this embodiment, the length of the packaging table 1 is twice the length of the hot pressing plate 2 .

[0028] In this embodiment, the motor 6 is a forward and reverse motor, which facilitates the forward and reverse rotation of the motor 6, drives the active sprocket 601 to rotate forward and reverse, and then drives the two driven sprockets 501 to rotate forward and reverse through the transmission chain 7, so that the transmission shaft 5 rotates, achieving the effect of driving the two swing arms 4 to rotate at the same time.

[0029] In this embodiment, the distance between the driving sprocket 601 and the driven sprocket 501 is equal to the distance between the two driven sprockets 501, ensuring that the contact distances between the driving sprocket 601 and the driven sprocket 501 and the transmission chain 7 are consistent, thereby ensuring normal transmission.

[0030] In this embodiment, a positioning assembly is fixedly provided on the outer surface of the packaging table 1, and the positioning assembly includes an electric telescopic rod 8, a connecting plate 801 and a concave frame 802. The electric telescopic rod 8 is fixedly provided at the center of the outer surface of the packaging table 1, and a connecting plate 801 is fixedly provided at the output end of the electric telescopic rod 8. Concave frames 802 are fixedly provided at both left and right ends of the connecting plate 801.

[0031] In this embodiment, the two concave frames 802 are located directly below the two transmission shafts 5 , and the two concave frames 802 are both attached to the outer surface of the concave frames 802 , so that the concave frames 802 can push the two swing arms 4 to rotate along the transmission shafts 5 when they rise.

[0032] In this embodiment, a temperature sensor is provided at the bottom of the hot pressing plate 2, and a controller is provided on the packaging table 1. The controller is electrically connected to the temperature sensor and the electric telescopic rod 8, so that the controller can control the extension and retraction of the electric telescopic rod 8.

[0033] By providing a positioning component, when the packaging machine is not used for a long time and the power on the hot pressing plate 2 is forgotten to be turned off, the temperature of the hot pressing plate 2 continues to rise. When the temperature of the hot pressing plate 2 rises to a specified temperature, the temperature sensor sends a signal to the controller, and the controller controls the electric telescopic rod 8 to extend. The electric telescopic rod 8 drives the connecting plate 801 and the two concave frames 802 to move upward. The top of the concave frame 802 contacts the swing arm 4 and pushes the swing arm 4 upward, so that the swing arm 4 rotates along the transmission shaft 5, so that the swing arm 4 drives the hot pressing plate 2 to swing, so that the hot pressing plate 2 is separated from the upper surface of the packaging table 1, which facilitates the heat dissipation of the hot pressing plate 2 and prevents the hot pressing plate 2 from being overheated and damaged.

[0034] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
