[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Example 1

[0021] like Figures 1-4 As shown, the present invention provides a double-tube heating and lifting device for filling equipment, comprising a cup holder conveying device 1 and a bottom plate 2 arranged at the bottom of the cup holder conveying device 1, a group of axial fixing plates 3 are fixedly connected to the top of the bottom plate 2, a bearing frame plate 4 is provided on one side of the axial fixing plate 3, a lifting arm shaft 5 is movably mounted on the bearing frame plate 4, a lifting arm 6 is movably connected to the outer wall of the lifting arm shaft 5, the lifting arm 6 is connected to a connecting rod 7 at one end away from the lifting arm shaft 5, the other end of the connecting rod 7 is connected to a U-shaped protrusion 8, and two lifting blocks are inserted on the top of the U-shaped protrusion 8. Lifting shaft 9, a magnetic base 10 is fixedly installed on the top of the lifting shaft 9, the magnetic base 10 is provided at the bottom of the cup holder conveying device 1, and two clamping blocks 11 are provided at the bottom of the U-shaped protrusion 8, one side of the two clamping blocks 11 is respectively connected to a joint bearing 12, the other end of the joint bearing 12 is fixedly connected to a hexagonal rod 13, the other end of the hexagonal rod 13 is connected to a cylinder 14, the cylinder 14 is fixedly installed on the top of the cup holder conveying device 1, and a stable guide mechanism is provided on one side of the clamping block 11, and a limiting mechanism is installed on the axial fixing plate 3.

[0022] In this embodiment, the stable guide mechanism includes a connecting plate 15, a guide rail 16 is fixedly installed on one side of the connecting plate 15, a slider 17 is slidably fitted on the outer wall of the guide rail 16, and the U-shaped protrusion 8 is fixedly mounted on the slider 17. The stable guide mechanism also includes a longitudinal plate 18 installed on both sides of the guide rail 16, and a limiting guide groove 19 is provided on the surface of the longitudinal plate 18. A needle bearing 20 is slidably provided inside the limiting guide groove 19, and one end of the needle bearing 20 is fixedly connected to the clamping block 11.

[0023] Specifically, the connecting plate 15 needs to be installed on the existing filling equipment when it is actually used. When the connecting rod 7 pushes the U-shaped protrusion 8, the connection between the U-shaped protrusion 8 and the slider 17 can ensure the vertical lifting of the U-shaped protrusion 8, which is beneficial to the stability of the lifting shaft 9. At the same time, the cooperation between the clamping block 11 and the needle bearing 20 enables the needle bearing 20 to move up and down in the limiting guide groove 19 when the clamping block 11 is pushed or pulled, thereby ensuring the smooth vertical lifting of the lifting shaft 9, which is beneficial to the lifting of the double-tube products by the magnetic base 10.

[0024] In the embodiment, the limiting mechanism comprises a main transmission shaft 21 installed on the shaft position fixing plate 3, an irregular cam 22 installed on the outer wall of the main transmission shaft 21, a curved bearing 23 attached to the side wall of the irregular cam 22, and the curved bearing 23 is installed on one side of the lifting arm 6.

[0025] Specifically, the main transmission shaft 21 needs to be connected with an external driving machine to ensure the continuous rotation of the irregular cam 22 during use, and the edge wall of the irregular cam 22 is designed with an arc that can cooperate with the rotation stop of the cup holder conveying device 1. In this way, when the concave end of the irregular cam 22 is rotated to a certain distance from the curved bearing 23, the operation of the air cylinder 14 can push the clamping block 11 and drive the lifting shaft 9 and the magnetic base 10 to complete the product lifting function. When the convex end of the irregular cam 22 contacts the curved bearing 23, one end of the lifting arm 6 can be lowered to ensure that the connecting rod 7 drives the U-shaped block 8 to descend, effectively preventing the clamping block 11 from rising, avoiding the problem of damage to the magnetic base 10 caused by the malfunction of the air cylinder 14 and the pushing of the clamping block 11.

[0026] In the embodiment, the top of each clamping block 11 is connected with a rubber washer 24 sleeved on the lifting shaft 9, and the rubber washer 24 is arranged at the bottom of the U-shaped block 8.

[0027] Specifically, by using the design of the rubber washer 24, when a single tube or a leaky tube occurs, the U-shaped block 8 can contact the rubber washer 24 when the single air cylinder 14 drives the clamping block 11 to reset, effectively reducing the collision between the U-shaped block 8 and the clamping block 11, while avoiding the problem of damage to the magnetic base 10 caused by the collision vibration force, effectively improving the service life of the magnetic base 10.

[0028] The working principle and use process of the present application: when in use, the connecting plate 15 needs to be installed on the existing filling equipment, and the main transmission shaft 21 is connected by the external driving machine to ensure the continuous rotation of the special-shaped cam 22. When the cup holder conveying device 1 drives the product to be conveyed, the product needs to be indirectly stopped at the top of the magnetic base 10. Thus, the continuous rotation of the special-shaped cam 22 makes the concave end thereof have a certain distance from the curved bearing 23. The working of the two air cylinders 14 can push the clamping block 11 and drive the lifting shaft 9 and the magnetic base 10 to complete the lifting during the product stopping period. The clamping block 11 can push the U-shaped lug 8 to rise during the lifting. The rising of the U-shaped lug 8 can drive the lifting arm 6 to rise through the connecting rod 7. After the lifting arm 6 rises, the curved bearing 23 can be contacted at the concave end of the special-shaped cam 22. Thus, when the convex end of the special-shaped cam 22 is contacted on the curved bearing 23, one end of the lifting arm 6 can drive the U-shaped lug 8 to descend through the connecting rod 7, so as to make the two air cylinders 14 work to drive the clamping block 11 and the lifting shaft 9 to descend, so as to ensure that the heated product falls on the cup holder conveying device 1 after lifting, and the product is conveyed after processing. At the same time, the descending of the U-shaped lug 8 effectively prevents the clamping block 11 from rising, avoiding the problem that the air cylinder 14 fails to push the clamping block 11 and causes the magnetic base 10 to damage the product.

[0029] Based on the above working principle, when a single pipe or a missing pipe appears in the processing process, the detection device on the existing filling equipment can analyze the detection data and control the working of the two air cylinders 14, so as to ensure that the corresponding air cylinder 14 works. Thus, after the single air cylinder 14 works, the clamping block 11 and the lifting shaft 9 can be pushed to rise, and the magnetic base 10 can lift the single product. Therefore, in the working state of the present application, no matter what kind of situation, such as single pipe, missing pipe or missing pipe, the device can make corresponding adjustment to complete the task of lifting the product, and has certain applicability.
