This allows the can body to be transported to multiple workstations for processing, with high conveying efficiency and stable, reliable operation.

Description

Technical Field

[0001] This utility model belongs to the field of metal can processing technology, and in particular relates to a multi-functional feeding device for metal cans. Background Technology

[0002] Metal cans are a common type of food container, usually made of metal materials such as iron, aluminum, and stainless steel. They are widely used because of their sturdy structure, corrosion resistance, and airtightness, which can protect food from the influence of the external environment. Examples include common chewing gum jars and mint jars.

[0003] The manufacturing of metal cans involves multiple processes. For example, the can body processing includes punching the hinged edges, rolling the bottom edge, and attaching the bottom cover. Achieving assembly line processing for these processes is crucial, especially when pursuing both production efficiency and quality. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional feeding device for metal cans, which aims to provide a device that can continuously transport the metal can body to multiple workstations so as to process the metal can body at different workstations.

[0005] To achieve the above objectives, this utility model provides a multifunctional feeding device for metal cans, including a cam divider, a rotary disk, a fixed cam, and a can body clamping mechanism. The cam divider is provided with a rotating flange located on the outer ring and a fixed flange located on the inner ring. The rotary disk is fixedly connected to the rotating flange. The rotary disk is provided with radially spaced radial guide seats and movable holes. The fixed cam is fixedly connected to the fixed flange. The bottom of the fixed cam is provided with an annular curved groove.

[0006] The can body clamping mechanism includes a front end block, a left trapezoidal block, a right trapezoidal block, and a rear end block passing through the movable hole. The front end block, the left trapezoidal block, the rear end block, and the right trapezoidal block are sequentially arranged to form a clamping cavity for clamping the can body. The front end block and the rear end block respectively engage with the inclined surfaces at both ends of the left trapezoidal block and the right trapezoidal block. The front end block is fixed on the rotating disk. A radial guide block extends from the rear end block and slides through and engages with the radial guide seat. A guide bearing is provided at the end of the radial guide block, and the guide bearing is accommodated in the annular curved groove.

[0007] The cam divider drives the rotating disk to rotate, causing the guide bearing to rotate along the annular curved groove. The pressure applied to the guide bearing by the annular curved groove forces the radial guide block to slide radially along the radial guide seat, thereby forcing the rear end block to move toward the front end block. Under the action of the inclined surface, the left trapezoidal block and the right trapezoidal block can move facing each other to clamp the can body located in the clamping cavity.

[0008] Optionally, multiple can-body clamping mechanisms are provided, and each can-body clamping mechanism is arranged radially around the center of the rotating disk. A lateral guide seat is provided on the rotating disk between the left trapezoidal block and the right trapezoidal block in two adjacent can-body clamping mechanisms. A left guide block and a right guide block are respectively extended from the left trapezoidal block and the right trapezoidal block, which are inserted into the lateral guide seat and slide with it. The adjacent left guide block and the right guide block are connected by a tension spring.

[0009] Optionally, the inner sides of the front end block and the rear end block are respectively provided with a front end block limiting groove and a rear end block limiting groove for limiting the position of the left trapezoidal block and the right trapezoidal block clamping the tank body.

[0010] The above-mentioned technical solutions of one or more of the multifunctional metal can feeding devices provided in this utility model embodiment have at least one of the following technical effects: In the multifunctional metal can feeding device of this utility model, after the cam divider is powered, the outer ring rotating flange can rotate, which can drive the rotating disk fixed to it to rotate. The fixed cam on the inner ring fixed flange remains fixed, so that the rotating disk can rotate relative to the fixed cam. When the rotating disk rotates, it will drive all the components installed on it to rotate, including the can body clamping mechanism, which rotates with the rotating disk. When the rotating disk rotates, the fixed cam remains fixed because the annular curved groove at the bottom of the fixed cam accommodates the guide bearing at the end of the radial guide block. As the circumference rotates, the guide bearing contacts the annular curved groove, resulting in different diameter changes. During this change, the radial guide block slides back and forth in the radial guide seat, which changes the size of the clamping cavity, thereby achieving clamping or releasing the can body. In this way, as the rotary table rotates, it drives the can body clamping mechanism to clamp and rotate the can body, thereby transporting the can body to multiple workstations for processing. The conveying efficiency is high, and the process is stable and reliable. Attached Figure Description

The following description is based on the accompanying drawings. Figures 1-9 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model, such as Figures 1-9 As shown, a multifunctional feeding device for metal cans is provided, including a cam divider 10, a rotating disk 20, a fixed cam 30, and a can body clamping mechanism 40. The cam divider 10 is provided with a rotating flange 11 located on the outer ring and a fixed flange 12 located on the inner ring. The rotating disk 20 is fixedly connected to the rotating flange 11. The rotating disk 20 is provided with radially spaced radial guide seats 22 and movable holes 21. The fixed cam 30 is fixedly connected to the fixed flange 12. The bottom of the fixed cam 30 is provided with an annular curved groove 31.

[0035] like Figures 4-5 As shown in Figure 8, the can body clamping mechanism 40 includes a front end block 41, a left trapezoidal block 42, a right trapezoidal block 43, and a rear end block 44 passing through the movable hole 21. The front end block 41, the left trapezoidal block 42, the rear end block 44, and the right trapezoidal block 43 are sequentially arranged to form a clamping cavity 45 for clamping the can body 100. The front end block 41 and the rear end block 44 respectively cooperate with the inclined surfaces at both ends of the left trapezoidal block 42 and the right trapezoidal block 43. The front end block 41 is fixed on the rotating disk 20. A radial guide block 441 extends from the rear end block 44 and slides through and cooperates with the radial guide seat 22. A guide bearing 442 is provided at the end of the radial guide block 441. The guide bearing 442 is accommodated in the annular curved groove 31.

[0036] The cam divider 10 drives the rotating disk 20 to rotate, causing the guide bearing 442 to rotate along the annular curved groove 31. The pressure applied to the guide bearing 442 by the annular curved groove 31 forces the radial guide block 441 to slide radially along the radial guide seat 22, thereby forcing the rear end block 44 to move toward the front end block 41. Under the action of the inclined surface, the left trapezoidal block 42 and the right trapezoidal block 43 can move facing each other to clamp the can body 100 located in the clamping cavity 45.

[0037] In the multifunctional metal can feeding device of this embodiment, after the cam divider 10 is powered, the outer rotating flange 11 on it can rotate, thus driving the rotating disk 20 fixed to it to rotate. The fixed cam 30 on the inner fixed flange 12 remains fixed, allowing the rotating disk 20 to rotate relative to the fixed cam 30. When the rotating disk 20 rotates, it drives all the components mounted on it to rotate, including the can body clamping mechanism 40, which rotates with the rotating disk 20. While the rotary disk 20 rotates, the fixed cam 30 remains stationary. This is because the annular curved groove 31 at the bottom of the fixed cam 30 houses the guide bearing 442 at the end of the radial guide block 441. As the circumference rotates, the guide bearing 442 contacts the annular curved groove 31, causing its diameter to change. This change in diameter drives the radial guide block 441 to slide back and forth within the radial guide seat 22, thus altering the size of the clamping cavity 45 and enabling the clamping or releasing of the can body 100. In this way, the rotation of the rotary disk 20 drives the can body clamping mechanism 40 to rotate while holding the can body 100, enabling the can body 100 to be transported to multiple workstations for processing. This method offers high efficiency, stability, and reliability.

[0038] Furthermore, the can body clamping mechanism 40 is used to clamp and position the outer periphery of the can body 100, which is limited between the upper and lower molds. When a force is applied to the rear end block 44 of the can body clamping mechanism 40, since the inner side of the rear end block 44 is inclined to engage with the left trapezoidal block 42 and the right trapezoidal block 43, the left trapezoidal block 42 and the right trapezoidal block 43 are forced to move inward. Thus, the left trapezoidal block 42 and the right trapezoidal block 43 clamp the can body 100 on the left and right sides respectively, and clamp the can body 100 through the front end block 41 and the rear end block 44 on the front and rear sides, thus completing the clamping and positioning of the outer periphery of the can body 100.

[0039] In one embodiment of this utility model, such as Figure 1 , 4As shown in Figure 6, multiple can-body clamping mechanisms 40 are provided, and each can-body clamping mechanism 40 is arranged radially around the center of the rotating disk 20. A lateral guide seat 23 located on the rotating disk 20 is provided between the left trapezoidal block 42 and the right trapezoidal block 43 of two adjacent can-body clamping mechanisms 40. A left guide block 421 and a right guide block 431 extend from the left trapezoidal block 42 and the right trapezoidal block 43, respectively, and slide in cooperation with the lateral guide seat 23. Adjacent left guide blocks 421 and right guide blocks 431 are connected by a tension spring 24. Specifically, the purpose of arranging multiple radially arranged can-body clamping mechanisms 40 in a ring on a rotating disk 20 is to enable the clamping of multiple can bodies 100 during continuous operation and to clamp the can bodies 100 to different workstations for processing. The left guide block 421 and the right guide block 431 are inserted into the lateral guide seat 23 to restrict their movement to the lateral direction only. This allows the left trapezoidal block 42 and the right trapezoidal block 43 to either clamp or release the left and right sides of the can body 100. When the radial guide block 441 causes the rear end block 44 to release its grip on the can body 100, the inclined surface and the tension spring 24 quickly cause the left trapezoidal block 42 and the right trapezoidal block 43 to release their grip on the left and right sides of the can body 100. This ingenious structural design is remarkable.

[0040] In one embodiment of this utility model, such as Figure 8 As shown, the inner sides of the front end block 41 and the rear end block 44 are respectively provided with a front end block limiting groove 410 and a rear end block limiting groove 440 for limiting the position of the left trapezoidal block 42 and the right trapezoidal block 43 clamping the can body 100. Specifically, by setting the front end block limiting groove 410 and the rear end block limiting groove 440, the extreme position of the front end block 41 and the rear end block 44 retracting into the clamping cavity 45 can be limited, avoiding excessive pressure on the can body 100 and damage to the can body 100.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
