[0002] In the production processes of many industries such as food, pharmaceuticals, and daily chemicals, capping is a crucial step. Product packaging takes many forms, and cans come in various shapes, including round and square. This necessitates that capping equipment be able to adapt to the positioning and capping requirements of cans of different shapes to ensure smooth production.
[0003] Currently, traditional capping machines often lack flexibility in can positioning. They can usually only be positioned and fixed for cans of specific shapes, making it difficult to adapt to the needs of cans of various shapes. This results in the need to frequently change equipment or make complex adjustments when processing cans of different shapes, and poor versatility. In view of this, we propose a torque-controllable capping machine. Utility Model Content

[0028] In this utility model, an auxiliary column 45 is fixedly connected to the top of the main frame 1, and a thread is provided at the bottom of the locking block 44. Two sets of auxiliary columns 45 are provided. The locking block 44 can be directly threaded to the adjusting column 41, and the bottom of the locking block 44 abuts against the surface of the synchronizing rod 42 to complete the fixing of the synchronizing rod 42.

The locking block 44 It can also be threaded onto the top of the auxiliary column 45. There are three sets of locking blocks 44. One set of locking blocks 44 is located on the adjusting column 41, and the other two sets of locking blocks 44 are each on one set of auxiliary columns 45. By tightening the locking blocks 44, the positioning block 43 is fixed on the auxiliary column 45, which strengthens the fixing effect of the positioning block 43. The outer wall of the plug-in sleeve 8 is plugged into the pushing block 46. Both the positioning block 43 and the pushing block 46 are provided with V-shaped notches to facilitate the fixing of the circular tank.

A locking slot is snapped into the top of the first pushing block 46, and the locking crank rod 9 can be snapped into the locking slot. A plug-in rod 11 is inserted into the inner wall of the first positioning block 43, and a second positioning block 12 is fixedly connected to the outer wall of the plug-in rod 11. A sliding rod 13 is slidably connected to the inner wall of the first positioning block 43.

A limit ring groove is opened on the plug-in rod 11, and the limit block 15 can slide into the limit ring groove.
[0030] Furthermore, the lifting assembly 3 includes an electric cylinder base 31, the output end of which is fixedly connected to a lifting plate 32. A guide column 33 is fixedly connected to the inner wall of the main frame 1, and a guide slide cylinder 34 is fixedly connected to the top of the main frame 1. A fixed cylinder 35 is slidably connected to the inner wall of the guide slide cylinder 34. The outer wall of the fixed cylinder 35 is fixedly connected to the inner wall of the lifting plate 32, and the inner wall of the lifting plate 32 is slidably connected to the outer wall of the guide column 33. The movement of the fixed cylinder 35 is guided by the guide slide cylinder 34. A support frame 36 is fixedly connected to the top of the fixed cylinder 35, and a motor 16 is fixedly connected to the inner wall of the support frame 36. A reducer 17 is fixedly connected to the output end of the motor 16. An input synchronous pulley set 18 is fixedly connected to the top of the support frame 36. The input synchronous pulley set 18 consists of two synchronous pulleys and a synchronous belt, which is prior art and will not be described in detail.
[0031] Furthermore, a coupling 20 is fixedly connected to the inner wall of the input synchronous pulley set 18, a torque sensor 19 is fixedly connected to the bottom of the coupling 20, a coupling 21 is fixedly connected to the bottom of the torque sensor 19, an output synchronous pulley set 22 is fixedly connected to the outer wall of the coupling 21, a synchronous shaft 23 is fixedly connected to the inner wall of the output synchronous pulley set 22, a pneumatic slip ring 24 is slidably connected to the outer wall of the synchronous shaft 23, a pneumatic gripper 25 is fixedly connected to the bottom of the synchronous shaft 23, a display screen 26 is fixedly connected to the main frame 1, and a protective plate 27 is fixedly connected to the outer wall of the support frame 36. The torque received by the torque sensor 19 is transmitted to the display screen 26 through an electrical signal. At this time, the torque can be adjusted and set through the display screen 26. The output synchronous pulley set 22 consists of two synchronous pulleys and a synchronous belt, which is existing technology and will not be described in detail. The pneumatic slip ring 24 is used to prevent air pipe entanglement, and the pneumatic gripper 25 is used for capping.
[0032] When in use, the tank is placed on the placement platform 2, and then the electric cylinder base 5 is started to move the movable plate 6, so that the movable rod 7, with the plug sleeve 8, approaches the adjusting column 41, and the pushing block 46 approaches the positioning block 43, which facilitates the fixing of the tank.
[0033] When the tank is square instead of round, a connecting rod 9 can be inserted into the push block 46 to make the push block 10 lock on the outside of the push block 46. By pulling the pull plate 14 upward, the sliding rod 13 drives the limiting block 15 to move synchronously, which makes it convenient to insert the connecting rod 11 into the positioning block 43. When the pull plate 14 is released, the limiting block 15 slides into the limiting ring groove on the connecting rod 11 through the reset of the compression spring, completing the limiting work of the connecting rod 11, so that the positioning block 12 is fixed on the outside of the positioning block 43. At this time, when the connecting sleeve 8 approaches the adjusting column 41, the push block 10 will approach the positioning block 12, which makes it convenient to clamp the square tank.
[0034] By activating the electric cylinder base 31, the lifting plate 32 can be raised and lowered, which in turn causes the fixed cylinder 35 to slide in the guide slide 34, thus completely changing the height of the support frame 36. After starting the motor 16, the power is transmitted to the reducer 17, which adjusts and optimizes the output speed and torque of the motor 16 to provide suitable power parameters for the capping operation. Then, the optimized power is smoothly and efficiently transmitted to the coupling 20 through the input synchronous pulley set 18, driving it to rotate synchronously. As the coupling 20 rotates, the torque sensor 19 connected to it begins to monitor the torque data in real time, providing key information for accurately controlling the capping torque. The power monitored by the torque sensor 19 is further transmitted to the output synchronous pulley set 22 through the coupling 21, driving it to rotate. The rotation of the output synchronous pulley set 22 drives the synchronous shaft 23 to rotate stably, and the synchronous shaft 23 finally transmits power to the pneumatic gripper 25, causing the pneumatic gripper 25 to rotate according to the preset torque and speed, successfully completing the capping operation. The entire power transmission process works in close coordination to ensure the efficiency, precision and stability of the capping operation.
