Description

Technical Field

[0001] This utility model relates to the field of product packaging, and in particular to a cardboard feeding mechanism. Background Technology

[0002] In the production process of various products, packaging paperboard is often required. In existing packaging operations, the packaging paperboard is pre-placed on a stack by operators, who then package the products before they proceed to the next step. This process requires operators to continuously pick up and place the packaging paperboard from the stacking platform onto the packaging platform, resulting in high labor intensity. Furthermore, the placement accuracy of manually placed packaging paperboard is inconsistent, affecting the precision and sealing of the product packaging.

[0003] Therefore, there is an urgent need for an automated mechanism to transport packaging cardboard to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a cardboard feeding mechanism, which aims to solve the technical problems of high labor intensity and low placement accuracy of existing packaging cardboard placement methods.

[0005] To achieve the above objectives, this utility model proposes a cardboard feeding mechanism, comprising a mounting frame, a lifting frame, a belt conveyor, a lifting component, a traversing component, and an adsorption component. The lifting frame is vertically movable and installed within the mounting frame. The lifting mechanism is driven and installed on the mounting frame and is used to drive the lifting frame to lift. The belt conveyor is installed on the lifting frame and is used to transport the packaged cardboard to the next process position. The traversing component is horizontally movable and installed on the lifting frame and is located above the belt conveyor. The adsorption component is installed on the traversing component and is used to adsorb the packaged cardboard.

[0006] The cardboard feeding mechanism of this utility model is further improved in that the mounting frame is cuboid, the lifting frame is rectangular and adapted to the mounting frame, and there are multiple lifting components, which are installed at intervals on the mounting frame.

[0007] The cardboard feeding mechanism of this utility model is further improved in that the lifting assembly includes a lifting drive, a first sprocket, a second sprocket and a chain. The lifting drive is fixed to the upper part of the mounting frame and is driven to the first sprocket. The second sprocket is rotatably mounted on the lifting frame and the chain is meshed and connected to the first sprocket and the second sprocket.

[0008] The cardboard feeding mechanism of this utility model is further improved in that the transverse component includes a transverse drive, a gear, a rack and a moving rod. The moving rod is horizontally movably mounted on the lifting frame. The rack is fixed to the moving rod. The transverse drive is fixed to the lifting frame. The transverse drive is driven to the gear. The gear meshes with the rack. The adsorption component is mounted on the moving rod.

[0009] The cardboard feeding mechanism of this utility model is further improved in that the adsorption assembly includes a connecting tube, a suction cup and a vacuum generator, the connecting tube is movably mounted on the moving rod and the connecting tube is connected between the suction cup and the vacuum generator.

[0010] The cardboard feeding mechanism of this utility model is further improved in that the two ends of the connecting tube are provided with lifting drive components, which are installed on the moving rod.

[0011] The cardboard feeding mechanism of this utility model is further improved in that the number of suction cups is multiple, and the multiple suction cups are connected to the connecting tube at intervals.

[0012] The cardboard feeding mechanism of this utility model is further improved in that the number of the transverse moving components is two, and the two transverse moving components are respectively installed on both sides of the lifting frame in a horizontally movable manner.

[0013] The technical solution of this utility model has the following beneficial effects: This invention relates to a cardboard feeding mechanism. A lifting assembly raises the lifting frame, and a lateral movement assembly moves the adsorption assembly horizontally onto the cardboard stack. The adsorption assembly picks up the cardboard and then returns to the lifting frame via the lateral movement mechanism.

[0022] like Figures 1-4 As shown, this utility model proposes a cardboard feeding mechanism, including a mounting frame 3, a lifting frame 4, a belt conveyor 7, a lifting component 5, a transverse component 6, and an adsorption component 8. The lifting frame 4 is vertically movable and installed inside the mounting frame 3. The lifting mechanism is driven and installed on the mounting frame 3 and is used to drive the lifting frame 4 to lift. The belt conveyor 7 is installed on the lifting frame 4 and is used to transport the packaged cardboard to the next process position. The transverse component 6 is horizontally movable and installed on the lifting frame 4 and is located above the belt conveyor 7. The adsorption component 8 is installed on the transverse component 6 and is used to adsorb the packaged cardboard.

[0023] Preferably, the mounting frame 3 is cuboid in shape, the lifting frame 4 is rectangular to fit the mounting frame 3, and there are multiple lifting components 5, which are installed at intervals on the mounting frame 3. In this embodiment, there are four lifting components 5, which are respectively installed at the four inner corners of the mounting frame 3, thereby achieving stable lifting of the lifting frame 4.

[0024] Preferred, such as Figure 4As shown, the lifting assembly 5 includes a lifting drive 501, a first sprocket 502, a second sprocket, and a chain 503. The lifting drive 501 is fixed to the upper part of the mounting frame 3 and is driven by the first sprocket 502. The second sprocket is rotatably mounted on the lifting frame 4. The chain 503 meshes with and connects to the first sprocket 502 and the second sprocket. The lifting assembly 5 allows the belt conveyor 7 to rise to a position approximately the same height as the stack of packaging cardboard 1 and to descend to a position consistent with the height of the next process step. This ensures that the packaging cardboard is placed at a low height, preventing displacement due to excessive height and affecting the accuracy of its position in the next process. Furthermore, the lifting drive 501 can be equipped with a support chain as needed to protect electrical wires and cables. In this embodiment, the four lifting assemblies 5 can also be driven by a single lifting drive 501, with adjacent first sprockets 502 connected by a connecting rod or chain 503. The lifting drive component 501 can be a motor.

[0025] Preferred, such as Figure 3 As shown, the lateral movement assembly 6 includes a lateral movement drive 601, a gear 602, a rack 603, and a moving rod 604. The moving rod 604 is horizontally movably mounted on the lifting frame 4. The rack 603 is fixed to the moving rod 604. The lateral movement drive 601 is fixed to the lifting frame 4 and is driven by the gear 602, which meshes with the rack 603. The adsorption assembly 8 is mounted on the moving rod 604. The lateral movement assembly 6 enables the adsorption assembly 8 to pick up materials above the stack of packaging cardboard 1 and then return to place the packaging cardboard onto the belt conveyor 7 for further transport. The lifting frame 4 is U-shaped, and the belt conveyor 7 is mounted on the web of the lifting frame 4. Slide rails 401 for horizontal movement of the moving rod 604 are provided on the relatively inner sides of the two side flanges of the lifting frame 4.

[0026] Preferred, such as Figure 4 As shown, the adsorption assembly 8 includes a connecting pipe 802, a suction cup 801, and a vacuum generator. The connecting pipe 802 is movably mounted on the moving rod 604 and connects the suction cup 801 and the vacuum generator. The negative pressure provided by the vacuum generator allows the suction cup 801 to adsorb the packaging cardboard, thereby enabling single-piece packaging cardboard picking operations.

[0027] Preferably, the connecting pipe 802 is provided with lifting drive components 803 at both ends, and the lifting drive components 803 are mounted on the moving rod 604. The lifting drive components 803 can be used to finely adjust the height of the suction cup 801, thereby adapting to packaging cardboard of different heights. The lifting drive component 803 can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc. In this embodiment, the lifting drive component 803 is a pneumatic cylinder.

[0028] Preferred, such as Figure 1 and Figure 2 As shown, there are multiple suction cups 801, which are connected to the connecting tube 802 at intervals to ensure sufficient adsorption force to adsorb the packaging cardboard.

[0029] Preferably, there are two lateral movement components 6, which are horizontally movable and installed on both sides of the lifting frame 4 to ensure the stability of the horizontal movement. In this embodiment, the lateral movement component 6 can also be driven by a lateral movement drive 601, with a fixed connecting rod 605 between the two gears 602 to achieve synchronous transmission. The two side flanges of the lifting frame 4 have openings for the connecting rod 605 to pass through, and the lateral movement drive 601 can be a motor.

[0030] When performing the loading operation, such as Figure 1 and Figure 4 As shown, the trolley 2 in the packaging workshop transports the corresponding size of the cardboard stack 1 to the material picking position of the mounting frame 3. The lifting component 5 lifts the lifting frame 4 to the highest point (the height of the lifting frame 4 can also be adjusted according to the height of the cardboard stack 1). The transverse drive component 601 drives the gear 602 to move the rack 603 and the moving rod 604 to one side of the cardboard stack 1 until the adsorption component 8 moves horizontally to the middle position of the cardboard stack 1. At this time, there is a certain distance between the suction cup 801 and the cardboard. The lifting drive component 803 extends to make the suction cup 801 stick to the cardboard. The vacuum generator is started, and the suction cup 801 picks up the top cardboard. The lifting drive component 803 retracts. The transverse drive component 601 drives the gear 602 to move the rack 603 and the moving rod 604 to one side of the mounting frame 3, so that the adsorption component 8 moves horizontally back into the lifting frame 4. The suction cup 801 places the cardboard on the belt conveyor 7, and the belt conveyor 7 transports the cardboard to the next process position.

[0031] This invention solves the technical problems of high labor intensity and low positioning accuracy in existing packaging cardboard placement methods. This invention can automatically place packaging cardboard. By setting operating data for each component, the components perform the cardboard feeding operation according to preset operating data, ensuring the positioning accuracy of the packaging cardboard and avoiding problems such as product packaging misalignment and poor sealing effect.
