Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron can processing technology, specifically an iron can clamping and positioning device. Background Technology
[0002] When printing trademarks and patterns on tin cans, or when spraying or hot stamping, the position must be strictly fixed to avoid misalignment of patterns or uneven coating due to slight movement. Therefore, the tin cans need to be fixed to ensure that the position and orientation of each tin can are completely consistent when entering the next process, thereby ensuring the stability of product quality in mass production and reducing the scrap rate caused by positioning deviation.
[0003] Currently, the most common tin can positioning and clamping devices on the market can only provide clamping force for tin cans of fixed size. However, most of them are designed for fixed size and can only be adapted to a single or a few specifications of tin cans. When the production line needs to switch to tin cans of different sizes and shapes, the clamps need to be disassembled and replaced, or even the entire device needs to be replaced, which results in long production changeover time and high costs.
[0004] Therefore, a tin can clamping and positioning device is proposed to address the above problems. Utility Model Content

[0007] Preferably, a connecting ear is fixedly installed at the bottom of the outer side of the annular limiting frame, and a pin hole is opened at the top of the connecting ear.
[0008] Preferably, a threaded sleeve is movably mounted on the top of the connecting ear, and a locating pin is fixedly mounted on the bottom of the threaded sleeve, with the locating pin movably embedded inside the pin hole.
[0009] Preferably, a drive motor is fixedly installed on one side of the top of the assembly frame, and the output end of the drive motor is configured as a threaded rod, which is meshed with a threaded sleeve.
[0010] Preferably, a T-shaped annular groove is provided at the top of the assembly frame and at the bottom of the annular limiting frame, and a connecting rod is fixedly installed at the bottom of the annular limiting frame, with a rotating wheel sleeved on the connecting rod.
[0011] Preferably, the square limiting sleeve is fixedly installed with limiting pins on both the upper and lower sides, and the limiting pins are rotatably embedded into the positioning holes.
[0012] The beneficial effects of this utility model are:

[0021] 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 scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a tin can clamping and positioning device, including an assembly frame 1. A circular through hole 2 is provided in the middle of the top of the assembly frame 1. An annular limiting frame 3 is movably installed in the middle of the top of the assembly frame 1. A positioning hole 4 is provided at the top of the edge of the annular limiting frame 3. A plurality of square limiting sleeves 5 are movably installed in the middle of the outer surface of the annular limiting frame 3. A transmission arm 6 is movably installed inside the square limiting sleeves 5. A groove 7 is provided in the middle of the end of the transmission arm 6. An arc-shaped abutment 8 is movably installed at the end of the groove 7. A plurality of positioning rods 9 are fixedly installed on the top of the assembly frame 1 and outside the annular limiting frame 3. The positioning rods 9 are movably embedded in the other end of the transmission arm 6.
[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 By cooperating with the circular through hole 2, the annular limiting frame 3, the square limiting sleeve 5, the transmission arm 6, and the arc-shaped abutment 8, the function of increasing the applicable range is realized. Thus, by adjusting the tilt state of the transmission arm 6, it can be adapted to various circular iron cans of different diameters, reducing the adjustment time during production changeover and improving the flexibility of the production line.
[0025] A connecting ear 10 is fixedly installed on the bottom of the outer side of the annular limiting frame 3, and a pin hole 11 is opened on the top of the connecting ear 10.
[0026] Reference Figure 3 and Figure 4The connection between the connecting ear 10 and the pin hole 11 achieves the function of limiting, thereby ensuring the stability of the connection between the threaded sleeve 12 and the annular limiting frame 3, so as to enable subsequent power transmission, and thus enabling the annular limiting frame 3 to rotate and adjust the working state of the transmission arm 6.
[0027] A threaded sleeve 12 is movably installed on the top of the connecting ear 10, and a positioning pin 13 is fixedly installed on the bottom of the threaded sleeve 12. The positioning pin 13 is movably embedded in the pin hole 11.
[0028] Reference Figure 1 and Figure 3 , Figure 4 The threaded sleeve 12 facilitates horizontal movement under the drive of the threaded rod 15, and then drives the annular limiting frame 3 to rotate through the connecting ear 10. The positioning pin 13 is easily inserted into the pin hole 11, firmly connecting the threaded sleeve 12 and the connecting ear 10, ensuring that the power transmission process is not disconnected.
[0029] A drive motor 14 is fixedly installed on one side of the top of the assembly frame 1. The output end of the drive motor 14 is configured as a threaded rod 15, which is meshed with the threaded sleeve 12.
[0030] Reference Figure 1 and Figure 3 The drive function is achieved through the cooperation of the drive motor 14 and the threaded rod 15. Thus, by engaging with the threaded sleeve 12, the rotational motion of the drive motor 14 is transferred to the annular limit frame 3, thereby driving the annular limit frame 3 to rotate, so as to subsequently drive the transmission arm 6 to adjust the working state.
[0031] A T-shaped annular groove 16 is provided on the top of the assembly frame 1 and at the bottom of the annular limiting frame 3. A connecting rod 17 is fixedly installed at the bottom of the annular limiting frame 3, and a rotating wheel 18 is sleeved on the connecting rod 17.
[0032] Reference Figure 2 and Figure 3 The T-shaped groove 16 provides a track for the rotating wheel 18, guiding the rotation of the annular limiting frame 3. The connecting rod 17 provides installation space for the rotating wheel 18, so that the annular limiting frame 3 can be connected to the rotating wheel 18 later. The rotating wheel 18 can roll in the T-shaped groove 16, reducing the friction between the annular limiting frame 3 and the assembly frame 1 when rotating, making the rotation of the annular limiting frame 3 smoother and more stable.
[0033] Limit pins 19 are fixedly installed on both the upper and lower sides of the square limiting sleeve 5. The limiting pins 19 rotate and embed into the positioning hole 4.
[0034] Reference Figure 4The limiting pin 19 is easily inserted into the positioning hole 4 to limit the rotation angle of the square limiting sleeve 5, prevent the transmission arm 6 from moving excessively, and ensure the safety of the device operation.
[0035] Working principle: When using this device, after the assembly frame 1 is fitted onto the outside of the iron can through the circular through hole 2, the drive motor 14 drives the threaded rod 15 to rotate. The threaded rod 15 drives the threaded sleeve 12 to move, which in turn drives the annular limiting frame 3 to rotate clockwise through the connecting ear 10. The rotation of the annular limiting frame 3 causes the square limiting sleeve 5 to push the transmission arm 6 to rotate. One end of the transmission arm 6 is limited by the positioning rod 9, causing the arc-shaped abutment 8 to move towards the center, fit against the outer wall of the can and apply a preset clamping force to complete the clamping and positioning of the iron can. During this process, the annular limiting frame 3 is limited inside the T-shaped annular groove 16 by the connecting rod 17 and the rotating wheel 18 at the bottom of the assembly frame 1.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
