Description

Technical Field

[0001] This utility model relates to the field of tank processing technology, specifically a tank rolling mechanism. Background Technology

[0002] In the field of can manufacturing, especially in the shaping of various metal or non-metal cans to meet specific dimensional and performance requirements, roll forming is a key and widely used technology. Roll forming can precisely control parameters such as the diameter and wall thickness of the can, enabling it to achieve the ideal shape and structural strength. It is widely used in various industries, including food packaging cans, chemical containers, and aerosol cans.

[0003] Many tank rolling processes rely on simple, manually operated equipment. Operators need to use simple tools, such as manual molding devices, to apply pressure to the tank for rolling. This method is not only extremely labor-intensive but also very inefficient. Because it depends entirely on manual operation, differences in strength control and operating techniques among different operators result in inconsistent and poorly uniform tank quality. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a tank rolling mechanism, which can effectively solve the problem of inconsistent tank quality and poor uniformity mentioned in the background technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tank rolling mechanism, including a frame: The frame is equipped with a tank-transferring mechanism for moving the tank to the processing point and a processing mechanism for rolling the tank. The tank transfer mechanism includes: The second base plate has a first cylinder fixed horizontally on its surface, and the movable end of the first cylinder is connected to a movable plate that adapts to the curvature of the tank body. Baffles are arranged parallel to both sides of the moving plate in the direction of movement to limit the movement trajectory of the tank; The pallet is positioned between two baffles and is driven to rise and fall by a second cylinder. The cylinder body of the second cylinder is fixedly connected to the base plate by a fixing plate. The processing mechanism includes: A first base plate has a servo motor fixed on top of it. The output end of the servo motor is connected in sequence to a reducer, a first gear plate and a second gear plate. A mold is fixedly connected below the second gear plate. An eccentric disc, which is coaxially fixed with the first gear disc, has a recess on its side; The Z-shaped rotating shaft has a pressing mold component hinged to its lower end to cooperate with the mold, and a roller hinged to its upper end. When the roller contacts the eccentric disk, it generates a prying effect: when the roller enters the non-recessed area of ​​the eccentric disk, the pressing mold component presses the mold to perform rolling; when it enters the recessed area, the pressing mold component releases the mold to allow filling. The reset assembly includes a fixing block fixed to the first substrate and a spring connected to the upper end of the Z-shaped rotating shaft.

[0006] Furthermore, a ring of anti-slip material is provided on the side of the mold.

[0007] Furthermore, the curvature of the roller matches the curvature of the recess.

[0008] Furthermore, a protrusion is provided above the eccentric disk, and a fixing seat is fixedly connected above the first substrate on one side of the eccentric disk, and an infrared sensor is fixed on the fixing seat.

[0009] Furthermore, the infrared sensor is connected to the control system, and the control system controls the start, stop, and speed adjustment of the servo motor based on the information obtained by the infrared sensor of the eccentric disk rotating one revolution.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the mechanism realizes the automation of tank transfer and rolling processing, reduces manual operation links, greatly shortens the processing time of a single tank, and can process more tanks in the same time, thereby significantly improving the overall production efficiency and meeting the needs of large-scale production.

[0011] Through mechanical structure and control, it can be ensured that the tank is subjected to uniform force and the deformation is controllable during the rolling process, resulting in high dimensional accuracy and good shape consistency of the processed tank, effectively guaranteeing the quality stability of the product and improving the product qualification rate.

Detailed Implementation

[0014] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0015] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0016] like Figure 1-5 As shown, this utility model provides a tank retraction mechanism, including a frame 1: The frame 1 is equipped with a tank-transferring mechanism 4 for transferring the tank to the processing point and a processing mechanism 2 for rolling the tank. The can-transfer mechanism 4 includes: The second base plate 41 has a first cylinder 42 fixed horizontally on its surface, and the movable end of the first cylinder 42 is connected to a movable plate 43 adapted to the curvature of the can body. The baffles 44, which are arranged parallel to both sides of the moving direction of the movable plate 43, are used to limit the movement trajectory of the tank. The support plate 45 is disposed between the two baffles 44 and is driven to rise and fall by the second cylinder 47 below. The cylinder body of the second cylinder 47 is fixedly connected to the base plate by the fixing plate 46. The processing mechanism 2 includes: A first substrate 21 has a servo motor 22 fixed on top of it. The output end of the servo motor 22 is connected in sequence to a reducer 23, a first gear 30 and a second gear 31. A mold 24 is fixedly connected below the second gear 31. An eccentric disk 28 is coaxially fixed with the first toothed disk 30 and has a recess 29 on its side. Z-shaped rotating shaft 26 has a lower end hinged to a pressing mold 27 that cooperates with the mold 24, and an upper end hinged to a roller 32. When the roller 32 contacts the eccentric disk 28, it generates a prying effect: when the roller 32 enters the non-recessed area 29 of the eccentric disk 28, the pressing mold 27 presses the mold 24 to perform rolling; when it enters the recessed area 29, the pressing mold 27 releases the mold 24 to allow filling. The reset assembly includes a fixing block 33 fixed to the first base plate 21 and a spring 34 connected to the upper end of the Z-shaped rotating shaft 26.

[0017] This facility automates tank transfer and rolling processes, reducing manual operations and significantly shortening the processing time for a single tank. It enables the processing of more tanks in the same amount of time, thereby significantly improving overall production efficiency and meeting the needs of large-scale production.

[0018] Through mechanical structure and control, it can be ensured that the tank is subjected to uniform force and the deformation is controllable during the rolling process, resulting in high dimensional accuracy and good shape consistency of the processed tank, effectively guaranteeing the quality stability of the product and improving the product qualification rate.

[0019] The first cylinder 42 on the second base plate 41 drives the movable plate 43 to move laterally. The movable plate 43 adapts to the curvature of the can body and can smoothly push the can. The baffles 44 arranged parallel on both sides restrict the movement trajectory of the can body, preventing the can body from deviating or tipping over during the transfer process, ensuring that the can body arrives at the processing point accurately, and preparing for the subsequent rolling process.

[0020] The support plate 45, located between the two baffles 44, is driven to rise and fall by the second cylinder 47. It can be flexibly adjusted according to the height of tanks of different sizes, so that the tank is always in a suitable processing position, thus improving the versatility of the equipment.

[0021] The servo motor 22 fixed on the first base plate 21 serves as a power source. The high-speed rotation of the motor is converted into a low-speed, high-torque output suitable for rolling processing by the reducer 23, providing stable and reliable power for subsequent gear transmission and mold 24 movement.

[0022] An eccentric disk 28, coaxially fixed with the first gear disk 30, has recesses 29 on its side. A roller 32, hinged to the upper end of the Z-shaped rotating shaft 26, contacts the eccentric disk 28. When the roller 32 enters the non-recessed area of ​​the eccentric disk 28, the change in shape of the eccentric disk 28 generates a prying effect, causing the pressing mold 27, hinged to the lower end of the Z-shaped rotating shaft 26, to press the mold 24, thus performing a rolling shrinking process on the can. When the roller 32 enters the recessed area, the pressing mold 27 releases the mold 24, facilitating the filling and removal of the can. This precise control of the pressing and releasing actions of the pressing mold 27 is achieved through the mechanical interaction between the eccentric disk 28 and the roller 32.

[0023] The fixing block 33 in the reset assembly is fixed on the first base plate 21. After the pressing part 27 completes the pressing action, the spring 34 connected to the upper end of the Z-shaped rotating shaft 26 uses the elastic force of the spring 34 to restore the Z-shaped rotating shaft 26 to the initial position, ensuring that the pressing part 27 can accurately and quickly release the mold 24, preparing for the next rolling process, and improving the continuity and stability of the process.

[0024] See Figure 2 and Figure 3 The mold 24 has a ring of anti-slip parts 25 on its side. During the rolling process, the mold 24 applies significant pressure to the can to change its shape. Without the anti-slip parts 25, the can would easily slide on the surface of the mold 24 under the strong pressure and possible rotational force. This sliding would lead to uneven rolling of the can, resulting in excessive or insufficient local deformation, affecting the dimensional accuracy and shape consistency of the can. The anti-slip parts 25 increase the friction between the can and the mold 24, effectively preventing the can from sliding and ensuring that the rolling force is applied evenly to the can, thereby guaranteeing the stable quality of the processed can.

[0025] The arc of the roller 32 matches the arc of the recess 29. During processing, the rotation of the eccentric disk 28 drives the roller 32. When the roller 32 enters the recess 29 area, the pressing mold 27 should release the mold 24 to allow filling of the can; when the roller 32 leaves the recess 29 and enters the non-recessed area, the pressing mold 27 should press the mold 24 to perform rolling. The matching arc of the roller 32 with the recess 29 ensures that the roller 32 smoothly and accurately enters and exits the recess 29, allowing the pressing mold 27 to perform pressing and releasing actions at the correct time, thereby achieving precise rolling processing control.

[0026] See Figure 1A protrusion 35 is provided above the eccentric disk 28. A fixing seat 36 is fixedly connected above the first base plate 21 on one side of the eccentric disk 28. An infrared sensor 37 is fixed on the fixing seat 36, which, in conjunction with the protrusion 35 on the eccentric disk 28, obtains information about one rotation of the eccentric disk 28. The rotation of the eccentric disk 28 drives the roller 32 to move, thereby controlling the pressing and releasing actions of the molding die 27. By detecting the protrusion 35 through the infrared sensor 37, the time for one rotation of the eccentric disk 28 can be accurately obtained, thus accurately determining the cycle of each molding action.

[0027] On automated production lines, the tank retraction mechanism may need to work in coordination with other equipment. By using infrared sensor 37 to acquire rotation information of eccentric disk 28, this signal can be used as a reference for synchronization control, enabling the retraction mechanism to operate precisely in sync with other equipment and avoiding production failures and product quality issues caused by asynchrony.

[0028] Each rotation of the eccentric disk 28 completes one full rotation, signifying the completion of a complete tank rolling process. Infrared sensors 37 continuously monitor the protrusions 35, allowing for real-time monitoring of each processing cycle. This ensures that each tank is subjected to the same rolling force and processing time, thereby guaranteeing product quality stability and consistency.

[0029] The infrared sensor 37 is connected to the control system. The control system controls the start, stop and speed adjustment of the servo motor 22 based on the information obtained by the infrared sensor 37 of the eccentric disk 28 rotating one revolution, thereby realizing the automated control of the processing process.
