Description

Technical Field

[0001] This utility model belongs to the field of integrated box forming technology, specifically, it relates to a feeding device for an integrated box forming machine. Background Technology

[0002] A cardboard box forming machine is an automated device used to fold and form cardboard into integrated packaging boxes. During the forming process, the feeding device is responsible for feeding the cardboard sheets one by one into the subsequent processing station, and its positioning accuracy directly affects the forming quality and production efficiency.

[0003] In existing integrated box forming machines, the side lugs of the cardboard are typically designed to be flush. Consequently, the guide and positioning mechanism for the cardboard is fixed and lacks adjustment capabilities. This design was sufficient for basic needs when producing only a single specification of cardboard. However, with the increasing demand for product diversification in the packaging industry, the cardboard structure has been modified accordingly—the side lug lengths of different specifications of integrated boxes vary and are no longer uniformly flush. When switching between producing different specifications of cardboard, the existing mechanism cannot adapt to these changes, resulting in the side lugs not being accurately positioned. This easily leads to offset or positioning deviations, severely impacting forming stability and yield. Utility Model Content

The technical solution adopted by this utility model is: a feeding device for a one-piece box forming machine, comprising:

[0005] The base includes a frame and a tray;

[0006] A positioning plate assembly, comprising a first support frame, a second support frame, a front positioning plate, and a first transmission assembly; the first and second support frames are movably connected to a base; the front positioning plate is connected to the first support frame via the first transmission assembly, and the first transmission assembly drives the front positioning plate to move in the front-back direction.

[0007] An adjustment assembly includes a first limiting plate, a second limiting plate, and a second transmission assembly. The first limiting plate is connected to a first support frame and the second transmission assembly, and the second limiting plate is connected to a second support frame and the second transmission assembly. The second transmission assembly is mounted on a frame, and the second transmission assembly drives the connected first and second limiting plates to move the first and second support frames synchronously left and right along the horizontal direction of the frame.

[0008] Furthermore, the first transmission assembly includes a first screw and a first power unit. The first power unit drives the first screw to rotate, and the other end of the first screw is connected to the front positioning plate, converting the rotational motion into the front positioning plate moving back and forth linearly along the axis of the first screw.

[0009] Furthermore, the base frame includes two vertical positioning frames on both sides, upper and lower horizontal frames, and a middle horizontal frame.

[0010] Furthermore, the second transmission assembly includes a second screw, several fixed seats, and a second power unit. The several fixed seats are used to support the second screw. The second screw is mounted on the intermediate horizontal frame through the fixed seats. The first limiting plate and the second limiting plate are threadedly engaged with the second screw. The second power unit drives the second screw to rotate, which in turn drives the first limiting plate and the second limiting plate, along with the first support frame and the second support frame, to move left and right synchronously along the direction of the horizontal frame.

[0011] Furthermore, the first transmission assembly includes a sprocket assembly, a chain, and a drive wheel; the first power unit drives the sprocket assembly to rotate through the drive wheel and the chain, and the sprocket assembly is connected to the first screw to rotate, thereby driving the front positioning plate to move in the front-back direction.

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 protection scope of the present utility model.

[0021] This embodiment provides a feeding device for a one-piece box forming machine, used for precise positioning of cardboard side ears, such as... Figure 1 As shown, it includes:

[0022] The base 1 includes a frame 11 and a tray 12; the tray on the base is used to place cardboard.

[0023] Positioning plate assembly 2, comprising a first support frame 21, a second support frame 22, a front positioning plate 23, and a first transmission assembly 24. The first support frame 21 and the second support frame 22 are movably connected to the base. The front positioning plate 23 is connected to the first support frame 21 via the first transmission assembly, which drives the front positioning plate 23 to move in the back-and-forth direction. Figure 2 As shown, the positioning plate assembly is used to adjust the depth of the side ears of different cardboard pieces. The front positioning plate 23 is elongated and used for pre-positioning the side ears of different cardboard sizes at different depths.

[0024] Adjustment component 3 includes a first limiting plate 31, a second limiting plate 32, and a second transmission component 33. The first limiting plate 31 is connected to a first support frame 21 and a second transmission component 33, respectively. The second limiting plate is connected to a second support frame 22 and a second transmission component 33, respectively. The second transmission component 33 is mounted on the frame. The second transmission component drives the connected first limiting plate 31 and second limiting plate 32 to move the first support frame 21 and the second support frame 22 synchronously left and right along the frame direction. Figure 3 As shown, the adjustment component is used to adjust the left and right position of the positioning plate assembly along the horizontal frame direction, to synchronize the left and right positions of the first support frame 21 and the second support frame 22, and to achieve precise positioning of the cardboard side ears.

[0025] The first transmission assembly 24 includes a first screw 241 and a first power unit 242. The first power unit 242 drives the first screw 241 to rotate. The other end of the first screw is connected to the front positioning plate 23, converting the rotational motion into a linear back-and-forth movement of the front positioning plate 23 along the axial direction of the first screw 241. The first transmission assembly can also be a hydraulic rod or a pneumatic rod, and the first power unit can also be pneumatic. In this embodiment, the first screw and the first power unit shown are motors. Using a motor to drive the screw makes it easier to control the distance the screw moves, facilitating precise movement of the front positioning plate to the position of the cardboard side ear.

[0026] The base frame 11 includes two vertical positioning frames 111 on both sides, upper and lower horizontal frames 112, and a middle horizontal frame 113. The two vertical positioning frames 111 are used for positioning the side walls and lower side walls of the cardboard as a whole. The two vertical positioning frames are equipped with linear bearings that can slide up and down according to different stacking amounts of cardboard. The horizontal frame of the base is used to facilitate the installation and fixing of the adjustment components.

[0027] The second transmission assembly 33 includes a second screw 331, several fixed seats 332, and a second power unit 333. The several fixed seats 332 are used to support the rotation of the second screw 331. The second screw 331 is mounted on the intermediate horizontal frame 113 via the fixed seats. The first limiting plate 31 and the second limiting plate 32 are threadedly engaged with the second screw 331. The second power unit 333 drives the second screw 331 to rotate, which in turn drives the first limiting plate 31 and the second limiting plate 32, along with the first support frame 21 and the second support frame 22, to move left and right synchronously along the horizontal frame direction. Figure 3 As shown, in this embodiment, three sets of L-shaped fixing seats 332 are installed on the intermediate horizontal frame by bolts. The second screw is rotatably located on the intermediate horizontal frame through the through hole on the fixing seat. The second power unit can also be pneumatic or other types. In this embodiment, the second power unit is a motor. The output end of the motor is connected to one end of the second screw 331. The second screw 331 drives the first limiting plate 31 and the second limiting plate 32 to move synchronously. The motor facilitates precise control of the moving distance, is easy to install, has a low cost, a simple structure, and can quickly adjust to achieve synchronous movement of the support frame.

[0028] The first transmission assembly 24 further includes a sprocket assembly 243, a chain 244, and a drive wheel 245. The first power unit 242 drives the sprocket assembly 243 to rotate via the drive wheel 245 and the chain 244. The sprocket assembly is connected to the first screw 241, which rotates and drives the front positioning plate 23 to move in the front-rear direction. The first transmission assembly can also use pulleys or a conveyor belt, etc. In this embodiment, the chain and sprocket assembly are used as the transmission assembly to drive the front positioning plate, which is convenient to install, has a simple structure, and is easy to adjust quickly to achieve smooth transmission.

[0029] The sprocket assembly 243 includes an upper sprocket assembly 2431 and a lower sprocket assembly 2432, which are mounted at the upper and lower ends of the first support frame 21 and connected by a chain 244. The sprocket assembly 243 has a nut seat that mates with the first screw 241, forming a screw-nut pair. A drive wheel 245 is fixedly connected to the motor, which drives the lower sprocket assembly 2432 to rotate via a chain (not shown), synchronously driving the upper sprocket assembly 2431 to rotate via a chain 224, thereby driving the first screw to rotate synchronously. The other end of the first screw 241 is connected to the front positioning plate 23, converting the rotational motion into linear forward and backward movement of the front positioning plate 23 along the axial direction of the first screw. Positioning the two sprocket assemblies at the upper and lower ends of the support frame and connecting them to the upper and lower ends of the front positioning plate ensures that the front positioning plate is vertically parallel to the support frame, enabling parallel forward and backward movement.

[0030] The adjustment assembly 3 further includes a slide rail assembly 34, which includes a slider 341 and a slide rail 342. The slide rail 342 is installed on the inner side of the upper and lower horizontal frames 112, and the slider 341 is installed on the upper and lower parts of the first support frame 21 and the second support frame 22, corresponding to and sliding with the slide rail 342. Figure 1 , Figure 4 As shown, the sliding of the slider and the slide rail enables the movable connection between the first support frame 21, the second support frame 22 and the base, so that the first support frame 21 and the second support frame 22 can move smoothly and stably in the left and right positions in the horizontal frame direction.

[0031] Further explanation with reference to the accompanying drawings: A certain specification of cardboard is stacked and placed on the tray of the base. The second power unit of the adjusting component 3 drives the second transmission component, which in turn moves the first support frame 21 and the second support frame 22 left and right along the horizontal frame, so that the first support frame 21 and the second support frame 22 are positioned on both sides of the bottom side wall of the cardboard. Then, the first power unit of the positioning plate component 2 drives the first transmission component, which moves the front positioning plate 23 on the first support frame 21 back and forth, so that the front positioning plate is precisely positioned on the side ear of the cardboard.
