Description

Technical Field

[0001] This utility model relates to the field of packaging and printing technology, and in particular to an automatic feeding device for printing packaging boxes. Background Technology

[0002] The packaging box printing industry has developed rapidly in recent years. With the popularization of automation technology, traditional manual material cutting methods can no longer meet the demands of high-efficiency and high-quality production. Currently, most mainstream packaging box printing production lines on the market use semi-automatic or fully automatic material cutting devices to improve production efficiency and reduce labor costs.

[0003] A search of existing technologies revealed a "packaging box unloading device" with the publication number "CN208345228U". This device uses an alarm circuit to alert staff to collect the boxes promptly, preventing subsequent boxes from piling up on the receiving and conveying assembly and causing obstruction of the box transport. However, in high-speed production environments, this automatic unloading device still exhibits instability, including deviations and tilts, which affect the stability of material movement within the device. Utility Model Content

[0004] Therefore, it is necessary to address the issue that the automatic feeding device still exhibits instability and tilting under high-speed production environments, affecting the stability of material movement within the feeding device. This necessitates providing an automatic feeding device for packaging box printing, comprising: a frame, with a servo motor fixedly connected to one side of the frame; and a feeding mechanism installed inside the frame, with its surface extending to the outside of the frame. The feeding mechanism includes a pushing assembly disposed inside the frame, with two electro-hydraulic actuators connected to one side of the pushing assembly. The electro-hydraulic actuators are fixedly connected to the side of the frame near the servo motor, and a lifting assembly is disposed on the side of the pushing assembly away from the electro-hydraulic actuators.

[0005] In one embodiment, the feeding assembly includes a connecting plate fixedly connected to the telescopic end of the electro-hydraulic push rod. A plurality of support frames are fixedly connected to the other side of the connecting plate. A fixing rod is fixedly connected to the inner wall of the frame between adjacent support frames. A support leg is fixedly connected to the lower end of the fixing rod away from the electro-hydraulic push rod. A push bar is fixedly connected to the surface of the support frame. The upper end of the push bar extends above the fixing rod.

[0006] In one embodiment, the lifting assembly includes a base disposed on the side of the frame away from the servo motor, a spiral tube fixedly connected to the inner wall of the base, a spiral rod slidably connected to the inner wall of the spiral tube, a circular plate fixedly connected to the upper end of the spiral rod, and a plurality of supporting vertical plates fixedly connected to the upper end of the circular plate.

[0007] In one embodiment, the upper end of the support frame is hinged to two hinge rods, and the upper ends of the two hinge rods are hinged to a movable rod.

[0008] In one embodiment, an adhesive strip is fixedly connected to the upper end of the movable rod, and the upper end of the adhesive strip extends above the fixed rod.

[0009] In one embodiment, a limiting ring is fixedly connected to the lower end of the circular plate, and two locking rings are engaged on the surface of the limiting ring.

[0010] In one embodiment, two electric push rods are fixedly connected to the upper end of the base, and the telescopic ends of the electric push rods are fixedly connected to the inner wall of the locking ring.

[0011] Beneficial effects

[0012] The aforementioned automatic feeding device for packaging box printing moves laterally by driving the telescopic end of the electro-hydraulic push rod. When the support frame moves toward the lifting assembly, the adhesive strip is gradually lifted upward under the guidance of the inclined groove. As the support frame moves, it drives the push strip to move synchronously. The push strip moves horizontally and moves in contact with the material. At the same time, the adhesive strip is rubbed by the fixed rods on both sides and moves upward in conjunction with the hinge rod against the moving rod. The material separates from the fixed rod and is supported by the adhesive strip, which prevents the material from tilting or shifting when pushed, thus ensuring the stability of the material push.

[0013] By setting up a lifting assembly, when the material is conveyed to the upper part of the support vertical plate, the electric push rod is driven to move the circular plate longitudinally in cooperation with the locking ring and the limiting ring. The circular plate drives the support vertical plate to move synchronously. In cooperation with the screw rod and the screw tube, the circular plate moves downward while driving the support vertical plate to rotate 90 degrees, so that the conveying direction is adjusted while the material moves downward.

[0026] The following is combined Figures 1-4 This invention describes an automatic feeding device for printing packaging boxes.

[0027] In one embodiment, an automatic feeding device for packaging box printing includes: a frame 1, a servo motor 2 fixedly connected to one side of the frame 1; and a feeding mechanism 3, which is installed inside the frame 1 and extends to the outside of the frame 1. The feeding mechanism 3 includes a pushing component 31 disposed inside the frame 1, two electro-hydraulic push rods 33 connected to one side of the pushing component 31, the electro-hydraulic push rods 33 being fixedly connected to the side of the frame 1 near the servo motor 2, and a lifting component 32 disposed on the side of the pushing component 31 away from the electro-hydraulic push rods 33.

[0028] It should be noted that: the frame 1 is a rectangular frame structure, welded from steel; the frame 1 is equipped with a conveying mechanism including a drive roller, a driven roller and a conveyor belt. The drive roller is driven by a motor, and the driven roller is mounted on both sides of the frame 1 by bearings.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, the feeding assembly 31 includes a connecting plate 311 fixedly connected to the telescopic end of the electro-hydraulic push rod 33. Multiple support frames 312 are fixedly connected to the other side of the connecting plate 311. A fixing rod 314 fixedly connected to the inner wall of the frame 1 is provided between adjacent support frames 312. A support leg 313 is fixedly connected to the lower end of the fixing rod 314 away from the electro-hydraulic push rod 33. A push bar 317 is fixedly connected to the surface of the support frame 312. The upper end of the push bar 317 extends above the fixing rod 314. Two hinge rods 318 are hinged to the upper end of the support frame 312. A moving rod 315 is hinged to the upper end of the two hinge rods 318. An adhesive strip 316 is fixedly connected to the upper end of the moving rod 315. The upper end of the adhesive strip 316 extends above the fixing rod 314.

[0030] In this embodiment, the device moves laterally by driving the telescopic end of the electro-hydraulic push rod 33. The telescopic end of the electro-hydraulic push rod 33 drives the support frame 312 to move synchronously through the connecting plate 311. The rubber strip 316 is made of soft rubber. The fixed rod 314 has evenly distributed inclined grooves on both sides. When the support frame 312 moves toward the lifting assembly 32, the rubber strip 316 is gradually lifted upward under the guidance of the inclined grooves. When the support frame 312 moves, it drives the push bar 317 to move synchronously. The push bar 317 moves horizontally and abuts against the material and moves with it. At the same time, the rubber strip 316 is rubbed by the fixed rods 314 on both sides. It cooperates with the hinge rod 318 to abut against the moving rod 315 and move upward. This allows the material to separate from the fixed rod 314, so that the material is supported by the rubber strip 316 and transported to the upper end of the support vertical plate 325.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the lifting assembly 32 includes a base 321 disposed on the side of the frame 1 away from the servo motor 2. A spiral tube 322 is fixedly connected to the inner wall of the base 321. A spiral rod 323 is slidably connected to the inner wall of the spiral tube 322. A circular plate 324 is fixedly connected to the upper end of the spiral rod 323. A plurality of supporting vertical plates 325 are fixedly connected to the upper end of the circular plate 324. A limit ring 328 is fixedly connected to the lower end of the circular plate 324. Two locking rings 327 are snapped onto the surface of the limit ring 328. Two electric push rods 326 are fixedly connected to the upper end of the base 321. The telescopic ends of the electric push rods 326 are fixedly connected to the inner wall of the locking rings 327.

[0032] In this embodiment, when the material is conveyed to the upper end of the support plate 325, the device drives the electric push rod 326 to move the circular plate 324 longitudinally in cooperation with the locking ring 327 and the limiting ring 328. At this time, the circular plate 324 drives the support plate 325 to move synchronously. In cooperation with the screw rod 323 and the screw tube 322, the circular plate 324 moves downward while driving the support plate 325 to rotate 90 degrees, so that the conveying direction is adjusted while the material moves downward.

[0033] Working principle: The telescopic end of the electro-hydraulic push rod 33 moves laterally. The telescopic end of the electro-hydraulic push rod 33 drives the support frame 312 to move synchronously through the connecting plate 311. When the support frame 312 moves, it drives the push bar 317 to move synchronously. The push bar 317 moves horizontally and moves in contact with the material. The rubber strip 316 is rubbed by the fixed rods 314 on both sides. With the cooperation of the hinge rod 318, it moves upward against the moving rod 315. The material separates from the fixed rod 314 and is supported by the rubber strip 316. The material is conveyed to the upper end of the support vertical plate 325. The electric push rod 326 drives the circular plate 324 to move longitudinally with the cooperation of the locking ring 327 and the limiting ring 328. The circular plate 324 drives the support vertical plate 325 to move synchronously. With the cooperation of the spiral rod 323 and the spiral tube 322, the circular plate 324 moves downward and drives the support vertical plate 325 to rotate, adjusting the conveying direction.

[0034] It should be noted that the servo motor 2 and electric actuator 326 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 2 and electric actuator 326 can be powered by the built-in power supply or by AC power. The specific power supply method depends on the situation and will not be elaborated here.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
