Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, and in particular to a material frame width adjustment device. Background Technology

[0002] With the continuous development of industrial automation technology and the deepening of intelligent manufacturing, more and more manufacturing industries are adopting automated equipment to improve production efficiency, reduce labor costs, and enhance product consistency. In automated production processes, material handling, stacking, and placement are indispensable components. Therefore, how to efficiently and safely complete the picking, placing, transferring, and stacking of products has become one of the key factors affecting overall production efficiency and product quality.

[0003] To meet the stacking requirements of products of different specifications, many automated equipment are equipped with adjustable-width trays. These trays can be adjusted in width according to the actual size of the product, ensuring that the product fits snugly against the inner wall of the tray after it is placed inside. This prevents the product from tilting or collapsing during stacking, ensuring the stability and neatness of the product placement, and effectively improving stacking efficiency and space utilization.

[0004] Currently, most commercially available adjustable width material frames use a motor-driven structure to achieve width adjustment. Specifically, a servo motor typically drives a synchronous belt, gear, or lead screw transmission mechanism to transmit power to the side wall of the material frame, driving it to move laterally and thus adjusting the internal space of the frame. This adjustment method has advantages such as high adjustment accuracy, fast response speed, and flexible control, and has been widely used in various palletizing, transfer, and warehousing equipment.

[0005] However, a significant problem exists in existing technologies: one motor can only drive one material frame for width adjustment. Although this "one-to-one" driving method has a simple structure and clear control logic, in scenarios where multiple workstations and multiple product specifications are produced simultaneously, multiple motors are required to drive multiple material frames respectively. This not only increases the manufacturing cost of the equipment but also increases the later maintenance and management costs, reducing the overall system's economy and scalability.

[0006] The technical content disclosed in the Chinese patent document (publication number: CN209118919U, patent name: a material stacking, storage and transfer device) is: by controlling the synchronous belt pulley to adjust the lateral width adjustment function of the lateral width adjustment device on the material stacking device through the width adjustment servo motor, silicon steel sheets of different specifications and widths are stacked from bottom to top in reverse and upright positions according to the iron core drawing.

[0007] As can be seen from the aforementioned patent documents, this material stacking, storage, and transfer equipment uses a motor to drive a synchronous belt pulley to adjust the stacking device. However, each width adjustment mechanism requires an independent servo motor and transmission components, resulting in a complex and costly overall system. Furthermore, the motors and transmission components require frequent maintenance during long-term operation, increasing the equipment's maintenance burden. In addition, the concentrated use of multiple motors leads to complex wiring, increased control difficulty, and higher energy consumption, limiting its widespread application in large-scale automated production lines. Utility Model Content

[0008] This utility model overcomes the shortcomings of existing technologies and provides a material frame width adjustment device. It incorporates a width adjustment cylinder, enabling the separation and connection of the device with the material frame. When a component malfunctions, the width adjustment cylinder can retract and pull back the second gear to separate it from the material frame gear, allowing for easy separation for repair or replacement. Furthermore, the same width adjustment device can be adapted to different material frames; simply adjusting the movement of the width adjustment cylinder according to the frame's specifications allows for width adjustment for various material frames.

[0009] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0010] A material frame width adjustment device includes a limiting component and a width adjustment component; the limiting component is used to restrict the degree of freedom of the first side of the material frame, so that it is stationary during the adjustment process; the width adjustment component is used to connect with the second side of the material frame and drive it away from or closer to the first side, the first side and the second side are parallel to each other, and the width of the material frame is adjusted by adjusting the distance between them.

[0011] The width adjustment component includes a width adjustment motor, which drives a second gear to rotate.

[0012] The second gear meshes with the material frame gear located on the material frame;

[0013] The material frame gear is connected to the material frame screw, which is connected to the screw seat on the second side.

[0014] When the lead screw of the material frame rotates, the lead screw seat moves along its axial direction, thereby driving the second side to move accordingly.

[0015] Furthermore, the width-adjusting motor is connected to the width-adjusting cylinder. When the width-adjusting cylinder extends, it pushes out the second gear to mesh with the material frame gear. When the width-adjusting cylinder retracts, it pulls back the second gear to separate it from the material frame gear.

[0016] Furthermore, the width-adjusting cylinder is connected to the width-adjusting base, the output end of the width-adjusting cylinder is connected to the width-adjusting motor base, and the width-adjusting motor is connected to the width-adjusting motor base.

[0017] Furthermore, pulleys are rotatably connected to both sides of the width-adjusting motor base, and the pulleys roll in contact with the front of the width-adjusting base.

[0018] Furthermore, the width-adjusting motor is connected to the first gear, and the second gear meshes with the first gear.

[0019] Furthermore, the width-adjusting motor mount is also equipped with a gearbox.

[0020] Furthermore, a solenoid valve is provided on the side of the width-adjusting seat away from the width-adjusting cylinder.

[0021] Furthermore, both the limiting component and the width adjusting component are connected to the base.

[0022] Furthermore, the limiting component includes a limiting cylinder, the output end of which is connected to a limiting block. The limiting block is provided with a locking position for locking the first side.

[0023] Furthermore, the cross-sectional shape of the locking position is adapted to the shape of the first side to provide surface contact limiting.

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] The device is equipped with a width-adjusting cylinder, allowing for the separation and connection of the width-adjusting device with the material frame. If a component malfunctions, the width-adjusting cylinder can retract and pull back the second gear to separate it from the material frame gear, making it easy to detach the component for repair or replacement. Furthermore, the same width-adjusting device can be adapted to different material frames; simply adjusting the movement of the width-adjusting cylinder according to the material frame's specifications allows for width adjustment for different material frames.

[0032] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0033] like Figures 1 to 4 As shown, a material frame width adjustment device includes a limiting component 2 and a width adjustment component 3. Both the limiting component 2 and the width adjustment component 3 are connected to a base 1, which provides a stable support foundation for the entire device, ensuring that the device will not shake or shift during operation, thereby guaranteeing the accuracy and stability of the width adjustment operation. The limiting component 2 is used to restrict the degree of freedom of the first side of the material frame, keeping it stationary during adjustment. The width adjustment component 3 is used to connect to the second side of the material frame and drive it away from or towards the first side. The first side and the second side are parallel to each other, and the width of the material frame is adjusted by adjusting the distance between them. This parallel relationship ensures the regularity of the shape of the material frame during the width adjustment process, avoiding twisting or deformation.

[0034] The core function of the limiting component 2 is to restrict the freedom of the first side of the material frame, keeping it stationary during width adjustment and providing a stable reference for subsequent width adjustment operations. It mainly consists of a limiting cylinder 201 and a limiting block 202. The output end of the limiting cylinder 201 is connected to the limiting block 202, and its extension / retraction movement drives the limiting block 202 to move. The limiting block 202 is equipped with a locking position 2021, which is used to lock the first side. The cross-sectional shape of the locking position 2021 is adapted to the shape of the first side, enabling surface contact limiting. This surface contact limiting method has many advantages: it can evenly distribute pressure, avoiding localized damage to the material frame; at the same time, surface contact provides greater friction and constraint force, more effectively restricting the movement of the first side of the material frame and ensuring its stability during width adjustment.

[0035] The width adjustment component 3 includes a width adjustment motor 305, which is connected to a first gear 306. A second gear 307 is meshed with the first gear 306. The transmission ratio between the first gear 306 and the second gear 307 is greater than 1:1, forming a reduction gear pair. Therefore, the width adjustment motor 305 can ultimately drive the second gear 307 to rotate. This reduction design can reduce the speed and increase the torque, making the width adjustment process smoother and more powerful. Under the drive of the width adjustment motor 305, the first gear 306 drives the second gear 307 to rotate, providing power for the movement of the second side of the material frame.

[0036] The second gear 307 meshes with a material frame gear mounted on the material frame; the material frame gear is connected to a material frame screw, which is connected to a screw seat on the second side; when the material frame screw rotates, the screw seat moves along its axial direction, thereby driving the second side to move accordingly, thus realizing the adjustment of the material frame width. Screw drive has the advantages of high transmission accuracy, high efficiency, and large load-bearing capacity, ensuring the accuracy and reliability of material frame width adjustment.

[0037] The width-adjusting motor 305 is connected to the width-adjusting cylinder 303. The function of the width-adjusting cylinder 303 is to control the engagement and disengagement of the second gear 307 with the material frame gear. When the width-adjusting cylinder 303 extends, it pushes out the second gear 307 to engage with the material frame gear. At this time, the power of the width-adjusting motor 305 can be transmitted to the material frame to achieve width adjustment. When the width-adjusting cylinder 303 retracts, it pulls back the second gear 307 to disengage from the material frame gear. This separable design facilitates the maintenance and installation of various components. When a component malfunctions, it can be easily separated for inspection or replacement. At the same time, the same width-adjusting device can be adapted to different material frames. By simply adjusting the action of the width-adjusting cylinder 303 according to the specifications of the material frame, the width of different material frames can be adjusted, greatly increasing the adaptability and versatility of the width-adjusting device.

[0038] The width-adjusting cylinder 303 is connected to the width-adjusting base 301. The output end of the width-adjusting cylinder 303 is connected to the width-adjusting motor base 304. The width-adjusting motor 305 is connected to the width-adjusting motor base 304. Pulleys 3041 are rotatably connected to both sides of the width-adjusting motor base 304. The pulleys 3041 roll in contact with the front of the width-adjusting base 301. The design of the pulleys 3041 reduces the friction between the width-adjusting motor base 304 and the width-adjusting base 301, so that the width-adjusting motor base 304 can move more smoothly under the push of the width-adjusting cylinder 303, thereby improving the operating efficiency and stability of the device.

[0039] The width-adjusting motor mount 304 is also equipped with a reduction gearbox 3051. In this invention, the reduction gearbox 3051 is a planetary reduction gearbox. The reduction gearbox 3051 can further reduce the output speed of the width-adjusting motor 305 and increase the torque, providing stronger power support for the width-adjusting operation. The reduction gearbox 3051 has the advantages of compact structure, high transmission efficiency, and high reliability, and can effectively protect the width-adjusting motor 305 and extend its service life.

[0040] A solenoid valve 302 is provided on the side of the width-adjusting seat 301 away from the width-adjusting cylinder 303. The solenoid valve 302 is mainly used to control the action of the width-adjusting cylinder 303. The solenoid valve 302 has the advantages of fast response speed and high control accuracy. It can quickly and accurately control the extension and retraction of the width-adjusting cylinder 303 according to the control signal, so as to achieve precise control of the width-adjusting process.

[0041] During the workflow, the material frame is first placed in a suitable position so that the limiting component 2 can be aligned with the first side of the material frame and the width adjusting component 3 can be aligned with the second side of the material frame, with the first and second sides being parallel to each other. Then, the operator sends a signal to the solenoid valve 302 through the control system to control the limiting cylinder 201 to move. The output end of the limiting cylinder 201 extends, driving the limiting block 202 to move towards the first side of the material frame. The locking position 2021 of the limiting block 202 contacts and locks the first side of the material frame. Since the cross-sectional shape of the locking position 2021 is adapted to the shape of the first side, surface contact limiting is achieved, restricting the degree of freedom of the first side and keeping it stationary during the adjustment process, providing a stable reference for subsequent width adjustment.

[0042] Then, the operator sends a signal to the solenoid valve 302 again through the control system, controlling the width-adjusting cylinder 303 to extend. When the width-adjusting cylinder 303 extends, it pushes the width-adjusting motor base 304. The pulleys 3041 on both sides of the width-adjusting motor base 304 roll on the front of the width-adjusting seat 301, reducing friction and allowing the width-adjusting motor base 304 to move smoothly, thereby pushing out the second gear 307, which meshes with the material frame gear on the material frame. Then, the width-adjusting motor 305 starts, and the power is further reduced in speed and increased in torque by the reduction gearbox 3051 before being transmitted to the first gear 306. The first gear 306 drives the second gear 307, which meshes with it, to rotate. Since the first gear 306 and the second gear 307 form a reduction gear pair with a transmission ratio greater than 1:1, the width-adjusting process is smooth and powerful.

[0043] The second gear 307 drives the meshing material frame gear to rotate, and the material frame gear drives the material frame screw to rotate. When the material frame screw rotates, it cooperates with the screw seat on the second side, causing the screw seat to move along the screw axis, thereby causing the second side of the material frame to move away from or closer to the first side, thus realizing the adjustment of the material frame width.

[0044] This invention incorporates a width-adjusting cylinder 303, enabling the separation and connection of the width-adjusting device with the material frame. When a component malfunctions, the width-adjusting cylinder can retract and pull back the second gear to separate it from the material frame gear, allowing for easy separation for repair or replacement. Furthermore, the same width-adjusting device can be adapted to different material frames; simply adjusting the movement of the width-adjusting cylinder according to the material frame's specifications allows for width adjustment for various material frames.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
