[0003] In today's technological field, a device called a vacuum extraction mechanism is commonly used in the production of blister boxes. This device is fixedly installed inside the blister forming machine, and its main function is to complete the production task through continuous suction and blowing. However, because this mechanism needs to operate continuously, it is prone to various malfunctions. Once a malfunction occurs, the repair process becomes very inconvenient because it is fixed inside the blister forming machine. This difficulty in repair not only reduces the production efficiency of blister boxes, but may also lead to a decrease in the yield rate, thus adversely affecting the entire production process.

[0004] Therefore, this utility model provides a vacuum extraction mechanism for blister box production to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a vacuum extraction mechanism for blister box production, such as... Figure 1-5 As shown, the vacuum extraction mechanism for blister box production includes a blister forming machine body 1. A bracket 2 is fixedly installed on the upper left side of the blister forming machine body 1. A forming mechanism 3 is provided inside the left end of the blister forming machine body 1. A vacuum chamber 4 is provided inside the left end of the blister forming machine body 1, and the vacuum chamber 4 is located below the forming mechanism 3. A vacuum tube 5 is fixedly installed inside the left end of the blister forming machine body 1 and is fixedly connected to the lower end of the vacuum chamber 4. A vacuum extraction mechanism body 6 is installed inside the right end of the blister forming machine body 1 and is connected to the right end of the vacuum tube 5. A sliding component for removing the vacuum extraction mechanism body 6 from the blister forming machine body 1 is provided inside the right end of the blister forming machine body 1. Two sets of locking components are provided on the left end of the sliding component.

[0025] When the vacuum extraction mechanism body 6 needs to be repaired or replaced, the maintenance personnel only need to operate to open the locking component. At this time, the sliding component is in the unlocked state, and the maintenance personnel can easily slide the vacuum extraction mechanism body 6 out of the thermoforming machine body 1, thereby realizing the quick installation and disassembly of the vacuum extraction mechanism body 6, which greatly saves maintenance time and improves maintenance efficiency.

[0026] The lower end of the vacuum tube 5 is connected to the vacuum extraction mechanism body 6 by a metal flexible tube, and the length of the connection between the lower end of the vacuum tube 5 and the vacuum extraction mechanism body 6 is the same as the length of the sliding component.

[0027] The design of the metal flexible tube not only ensures the flexibility of the connection between the vacuum tube 5 and the vacuum extraction mechanism body 6, allowing the vacuum extraction mechanism body 6 to extend through the metal flexible tube at the connection point when sliding, but also ensures that the sliding component is not obstructed during movement, further improving the smoothness of operation.

[0028] The sliding assembly includes a slide 7, which is fixedly installed on the right end of the vacuum forming machine body 1. A motor 8 is fixedly installed on the right side of the slide 7. A screw 9 is rotatably installed inside the slide 7. The right end of the screw 9 is connected to the output shaft of the motor 8. A slider 10 is threaded onto the screw 9. A mounting plate 11 is fixedly installed on the upper side of the slider 10. The vacuum extraction mechanism body 6 is fixedly installed on the mounting plate 11. The lower side of the mounting plate 11 is flush with the upper side of the slide 7.

[0029] The output shaft of motor 8 drives screw 9 to rotate. Since screw 9 and slider 10 are connected by a thread, the rotation of screw 9 will drive slider 10 to move left and right. When slider 10 moves left and right, it will drive the mounting plate 11 fixed on its upper side and the vacuum extraction mechanism body 6 fixed on the mounting plate 11 to move left and right synchronously, thereby realizing the function of driving vacuum extraction mechanism body 6 to slide inside the thermoforming machine body 1.

[0030] Guide blocks 12 are fixedly installed on both the front and rear sides of the slider 10, and guide rods 13 are fixedly installed on both the front and rear sides of the carriage 7. The two sets of guide blocks 12 are slidably sleeved on the two sets of guide rods 13.

[0031] The sliding sleeve design between the guide block 12 and the guide rod 13 not only provides stable guidance for the left and right movement of the slider 10, ensuring the smoothness of the slider 10 during movement, but also enhances the structural strength of the entire sliding assembly, making it more durable and reliable.

[0032] The locking component includes a mounting member 14 which is mounted at the left end of the mounting plate 11. A first hinge member 15 is fixedly installed on the left side of the mounting member 14. A first connecting member 16 is rotatably installed on the mounting member 14. The left end of the first connecting member 16 is rotatably installed with a second connecting member 17. A limiting block 18 is installed between the first hinge member 15 and the second connecting member 17. A pneumatic telescopic rod 20 is fixedly installed on the mounting plate 11. The left end telescopic shaft of the pneumatic telescopic rod 20 is rotatably installed with a hinge rod 21. The hinge rod 21 is rotatably connected to the first connecting member 16. A fixing member 19 is fixedly installed on the inner wall of the right end of the blister molding machine body 1.

[0033] In practical applications, when it is necessary to lock the position of the vacuum extraction mechanism body 6, the pneumatic telescopic rod 20 is used to drive the hinge rod 21 to expand and contract, thereby driving the first connecting member 16, the second connecting member 17 and the limiting block 18 to rotate. And when the limiting block 18 rotates, it is limited to rotate by the first hinge member 15 until the limiting block 18 is completely engaged with the fixing member 19, thus ensuring the stability and reliability of the entire vacuum extraction mechanism during the working process.

[0034] One end of the limiting block 18 opposite to the fixing member 19 is in a U-shaped form, and the fixing member 19 is inserted into the limiting block 18.

[0035] Since one end of the limiting block 18 opposite to the fixing member 19 is designed in a U-shaped form and the fixing member 19 is inserted into the limiting block 18, the engagement between the two is very firm, which can effectively prevent the vacuum extraction mechanism body 6 from sliding or shifting within the blister molding machine body 1. Maintenance personnel can easily lock and unlock the vacuum extraction mechanism body 6 quickly by operating the locking component, thus greatly improving the convenience and efficiency of the maintenance work.

[0036] Working principle: In use, motor 8 is started first. The output shaft of motor 8 drives screw 9 to rotate. Since screw 9 and slider 10 are connected by a thread, the rotation of screw 9 will cause slider 10 to move left and right within slide 7. When slider 10 moves left and right, it will drive the mounting plate 11 fixed on its upper side and the vacuum extraction mechanism body 6 fixed on the mounting plate 11 to move left and right synchronously. When the vacuum extraction mechanism body 6 moves to the appropriate position, it drives two sets of hinge rods 21 to extend and retract through two sets of pneumatic telescopic rods 20, thereby driving two sets of first connecting parts 16, two sets of second connecting parts 17 and two sets of... The limiting block 18 rotates with the two sets of mounting parts 14 and the two sets of first hinge parts 15. When the two sets of limiting blocks 18 rotate, they are limited by the first hinge parts 15 until the two sets of limiting blocks 18 are completely engaged with the two sets of fixing parts 19 fixed inside the vacuum forming machine body 1, thereby locking the position of the vacuum extraction mechanism body 6. When the vacuum extraction mechanism body 6 needs to be repaired or replaced, the locking component can be reversed to separate the limiting block 18 from the fixing parts 19. The maintenance personnel can easily slide the vacuum extraction mechanism body 6 out of the vacuum forming machine body 1, thereby realizing the quick installation and disassembly of the vacuum extraction mechanism body 6.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
