In order to ensure that the screw ring 34 does not rotate when driven by the threaded rod 33, the forming tube pushing platform 36 is connected through the connecting rod 35, thereby ensuring that the threaded rod 33 is rotated. When rotating, the screw ring 34 can drive the forming tube pushing platform 36 to move. The front surface of the connecting rod 35 is fixedly connected to the forming tube pushing platform 36, and the right surface of the forming tube pushing platform 36 is fixedly connected to the sliding bar 4. The sliding bar 4 passes through the forming tube positioning platform 5 and is slidably connected to the forming tube positioning platform 5. In order to ensure that the forming tube pushing platform 36 is more stable during movement, three groups of sliding bars 4 are arranged in a circular array to ensure that the forming tube pushing platform 36 is more stable during movement. The sliding bar 4 passes through the molding machine body 2 and is slidably connected to the molding machine body 2. A through groove 6 is provided on the right surface of the molding tube pushing platform 36, and a baffle 7 is slidably connected to the inner surface of the through groove 6. In order to ensure that the baffle 7 is not damaged due to extrusion when the molding tube pushing platform 36 contacts the molding tube positioning platform 5, a through groove 6 is provided on the molding tube pushing platform 36 so that the baffle 7 can be retracted.

[0026] In this embodiment, through the mutual cooperation of the motor 32, the threaded rod 33 and the screw ring 34, when a plastic-coated molding tube is placed on the molding tube pushing platform 36, the plastic-coated molding tube can be automatically pushed into the plastic-coating machine body 2, effectively reducing the workload of workers and improving production efficiency.

[0027] Embodiment 2

[0028] See also Figure 2-Figure 3On the basis of the first embodiment, the utility model provides a technical solution: preferably, a limiting mechanism 8 is provided on the outer arc surface of the slide bar 4, and the limiting mechanism 8 includes: a sleeve 81, the sleeve 81 passes through the slide bar 4 and is slidably connected with the slide bar 4, a positioning rod 82 is slidably connected to the inner surface of the sleeve 81, a first spring 83 is slidably connected to the inner surface of the sleeve 81, an H-shaped fixing plate 9 is fixedly connected to the outer arc surface of the sleeve 81, and an induction plate 10 is rotatably connected to the inner surface of the H-shaped fixing plate 9, and a side of the induction plate 10 away from the H-shaped fixing plate 9 is rounded, and a side of the H-shaped fixing plate 9 is rounded, when the H-shaped fixing plate 9 moves through the forming tube pushing platform 36 and contacts with the forming tube positioning platform 5, the sleeve 81 can be separated from the slide bar 4 under the condition of being squeezed, and at this time, most of the plastic-coated forming tube is moved forward. The inner surface of the H-shaped fixed plate 9 is slidably connected with a push rod 11, and the side of the push rod 11 close to the slide bar 4 is in an arc shape. In order to ensure that the push rod 11 can push the outer arc surface of the slide bar 4, thereby pushing the entire limiting mechanism 8 out of the slide bar 4, the side of the push rod 11 close to the slide bar 4 is designed to be in an arc shape, which is more convenient for pushing the slide bar 4. The side of the push rod 11 away from the slide bar 4 is hinged with one end of the bracket 12, and the other end of the bracket 12 is hinged to the induction plate 10. The inner surface of the H-shaped fixed plate 9 is fixedly connected with a fixing plate 13, and the inner surface of the H-shaped fixed plate 9 is provided with a second spring 14, and the fixing plate 13 is fixedly connected to one end of the second spring 14, and the other end of the second spring 14 is fixedly connected to the push rod 11.

[0029] In this embodiment, by providing the insert sleeve 81, the positioning rod 82 and the slide rod 4, the overmolded tube is positioned when it is placed on the molding tube pushing platform 36 to ensure that the overmolded tube can enter the overmolding machine body 2, making the entire pushing mechanism 3 more stable.

[0030] Working principle: when a spring tube needs to be made, the worker places the plastic forming tube on the baffle 7, inserts the sleeve 81 onto the slide bar 4, and the positioning rod 82 limits the plastic forming tube at the center point of the forming tube pushing platform 36 through the elasticity of the first spring 83, and then starts the motor 32. After the output shaft of the motor 32 drives the threaded rod 33 to rotate, the screw ring 34 drives the forming tube pushing platform 36 to move toward the direction of the plastic forming machine body 2 through the connecting rod 35. Before the forming tube pushing platform 36 contacts the forming tube positioning platform 5, the induction plate 10 first contacts with the forming tube positioning platform 5. After being squeezed, the induction plate 10 will shrink into the H-shaped fixed plate 9, and drive the push rod 11 through the bracket 12 to move the push rod 11 outward to resist the slide bar 4, thereby automatically squeezing the sleeve 81 out of the slide bar 4. After the induction plate 10 is no longer under force, the induction plate 10 returns to its original position through the elastic force of the second spring 14. At the same time, the baffle 7 will shrink into the through groove 6 after being squeezed by the forming tube positioning platform 5, and the formed plastic-coated tube will completely enter the plastic-coating machine body 2.
