Abstract
Description
Technical Field
[0001] The utility model relates to a pushing device, in particular to a pushing device for a thermos flask liner. Background Art
[0002] The pushing and transferring of the liner is a crucial step in the production of thermos bottles. Traditional pushing methods often present numerous problems, such as the inability to effectively secure the liner during the pushing process, which can cause it to shake, shift, or even be damaged, impacting product quality and production efficiency. Furthermore, due to the lack of effective buffering and protective measures, the liner may collide with equipment components during the pushing process, causing scratches or cracks on the surface. Furthermore, traditional pushing devices lack flexibility when adapting to liner sizes of varying sizes, making it difficult to meet diverse production needs. Utility Model Content
[0003] In order to solve the above problems, the following technical solutions are proposed:
[0004] The device for pushing the liner of a thermos bottle includes a conveyor belt, a mounting base is provided on the conveyor belt, a hollow cylindrical limiting cylinder is fixedly connected to the mounting base, the liner is placed in the limiting cylinder, a lower airbag is provided on the mounting base at the bottom of the limiting cylinder, and a side airbag is provided on the side wall of the limiting cylinder.
[0005] Furthermore, the lower airbag is a retractable airbag that can be retracted in the vertical direction, and the lower airbag is connected to the side airbag through a vent pipe.
[0006] Furthermore, an oil cylinder is provided on the top of the limiting cylinder, and a pressure plate is fixedly connected to the end of the telescopic rod at the bottom of the oil cylinder.
[0007] Furthermore, a rubber pad is provided at the bottom of the pressing plate.
[0008] Furthermore, the oil cylinder is mounted on a mounting platform, and one side of the mounting platform is mounted on the mounting base through a mounting frame.
[0009] The beneficial effects of the utility model are as follows:
[0010] By setting up a hollow cylindrical limiting cylinder, this device can provide accurate positioning and guidance for the inner liner, effectively preventing the inner liner from shaking and deflecting during the pushing process, greatly improving the pushing stability and accuracy, and thus ensuring product quality.
[0011] Airbags located at the bottom and side walls of the retaining tube provide comprehensive cushioning protection for the liner. The lower airbag is vertically retractable and, through communication with the side airbags, adaptively adjusts its expansion based on the size and shape of the liner, preventing hard contact between the liner and the device and reducing the risk of damage.
[0012] The oil cylinder and pressure plate installed on the top can further fix the inner liner, especially when encountering bumps or acceleration during transportation, ensuring the stable position of the inner liner and preventing it from accidentally slipping.
[0013] The rubber pad at the bottom of the pressure plate increases the friction with the inner liner, and also acts as a buffer to protect the surface of the inner liner from damage.
[0014] The entire device features a rationally designed structure. The mounting platform and mounting bracket ensure secure installation of components such as the oil cylinder, improving the equipment's reliability and service life. Furthermore, individual components can be easily adjusted and maintained to accommodate the demands of pushing liners of varying specifications, enhancing production versatility and flexibility.

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] The device for pushing the inner liner 7 of the thermos flask includes a conveyor belt 1, a mounting base 2 is provided on the conveyor belt 1, a hollow cylindrical limiting cylinder 31 is fixedly connected to the mounting base 2, the inner liner 7 is placed in the limiting cylinder 31, a lower airbag 4 is provided on the mounting base 2 at the bottom of the limiting cylinder 31, and a side airbag 32 is provided on the side wall of the limiting cylinder 31. The lower airbag 4 is a retractable airbag that can be extended and retracted in the vertical direction, and the lower airbag 4 is connected to the side airbag 32 through a ventilation tube. A cylinder 6 is provided at the top of the limiting cylinder 31, and a pressure plate 61 is fixedly connected to the end of the telescopic rod at the bottom of the cylinder 6. A rubber pad 62 is provided at the bottom of the pressure plate 61. The cylinder 6 is installed on the mounting platform 52, and one side of the mounting platform 52 is installed on the mounting base 2 through the mounting frame 51.
[0022] The working principle of this utility model is as follows:
[0023] During work, the thermos flask liner 7 is placed in the hollow cylindrical limiting tube 31 on the mounting base 2 on the conveyor belt 1. First, the liner 7 falls into the limiting tube 31, and now the limiting tube 31 performs preliminary positioning and guidance on it.
[0024] The lower airbag 4, located at the bottom of the retaining tube 31, plays a crucial role. When the lower liner 7 is inserted, gravity compresses the lower airbag 4, which is vertically expandable and retractable. The compressed gas within the lower airbag 4 flows through the vent tube to the side airbags 32, causing them to inflate. The expansion of the side airbags 32 automatically adjusts based on the size and shape of the liner 7, tightly hugging the liner 7 from the sides and providing lateral support and cushioning.
[0025] Next, the oil cylinder 6, located at the top of the retaining cylinder 31, begins to operate. The telescopic rod at the bottom of the oil cylinder 6 extends, driving the pressure plate 61 fixed to its end downward. The rubber pad 62 at the bottom of the pressure plate 61 contacts the top of the inner liner 7, applying downward pressure to further secure the inner liner 7 and prevent it from bouncing or moving during transportation.
[0026] Throughout the entire operation of the conveyor belt 1, the inner liner 7 remains stably fixed and protected. Even if the conveyor belt 1 speed changes or encounters external interference, the liner 7 can be safely and smoothly pushed to the designated position due to the coordinated action of the lower airbag 4, the side airbag 32 and the pressure plate 61.
[0027] When it is necessary to push the inner liner 7 of different specifications, it is only necessary to appropriately adjust the parameters such as the stroke of the oil cylinder 6 and the inflation pressure of the airbag according to the size and shape of the inner liner 7 to effectively push the inner liner 7 of different specifications.
[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
