Description

Technical Field

[0001] This utility model relates to the field of paper box forming, and in particular to the paper feeding device of paper box forming equipment. Background Technology

[0002] Paper box forming equipment uses automated technology to process cardboard into finished paper boxes, which not only improves production efficiency but also ensures consistent box quality and a hygienic production environment. These paper boxes are environmentally friendly, lightweight, and can be printed on, making them popular with consumers. As the demand for paper boxes increases, paper box forming equipment replaces manual labor, improving efficiency while maintaining quality. Because the pressing and molding process in paper box forming equipment requires a certain amount of time, the feeding rhythm of the cardboard is particularly important. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a paper feeding device for a cardboard box forming equipment that allows for control of the cardboard feeding rhythm.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A paper feeding device for a paper box forming equipment includes a frame, on which a lifting plate and a conveyor belt are mounted. The lifting plate has a lifting surface, and the conveyor belt has a conveying surface. The lifting plate is positioned to the side of the conveyor belt. The lifting plate is mounted on a rotating shaft, which is connected to a servo motor. The servo motor drives the lifting plate to reciprocate between a lifting position and a releasing position. When the lifting plate is in the lifting position, the material-bearing surface of the lifting plate is higher than the conveying surface of the conveyor belt, and the lifting plate in the lifting position separates the material from the conveyor belt. When the lifting plate is in the releasing position, the material-bearing surface of the lifting plate is not higher than or intersects with the conveying surface of the conveyor belt, and the lifting plate in the releasing position causes the bottom of the material to contact the conveyor belt, and the conveyor belt delivers the material.

[0005] This invention utilizes a servo motor to drive a paper-lifting plate between a paper-lifting position and a paper-discharging position. When the paper-lifting plate is in the paper-lifting position, the material separates from the conveyor belt, stopping the conveyor and protecting the material surface. When the paper-lifting plate is in the paper-discharging position, the bottom of the material contacts the conveyor belt, which then delivers the material. The periodic movement of the paper-lifting plate controls the material feeding rhythm, precisely controlling the paper feeding pace and ensuring stable paper delivery.

[0006] Preferably, the servo motor drives the lifting plate to swing around a rotating shaft, which causes the material-bearing surface of the lifting plate to intersect with the conveying surface of the conveyor belt, and the lifting surface of the lifting plate is inclined at the discharge end. The swinging of the lifting plate causes part of the material to come into contact with the conveyor belt, and the conveyor belt delivers the material out.

[0007] Preferably, a lifting drive assembly is provided between the rotating shaft and the lifting plate. This lifting drive assembly ensures that the material-bearing surface of the lifting plate is not higher than the conveying surface of the conveyor belt. The lifting drive assembly includes a mounting block, rollers, and a support shaft. The mounting block is fixedly mounted on the rotating shaft and hinged to one end of the lifting plate. The rollers are respectively located at both ends of the lifting plate, and the support shaft is correspondingly located below the rollers, engaging with them. The outer surface of the support shaft has a guide slope, along which the rollers move. A servo motor drives the lifting plate to perform lifting and lowering actions, ensuring that the material-bearing surface is at the same level as the conveyor surface or that the material-bearing surface is lower than the conveyor surface, so that the bottom of the material contacts the conveyor belt, thus conveying the material out.

[0008] Furthermore, a reset elastic element is connected between the lifting plate and the mounting block. When the lifting plate is in the paper-lifting position, the reset elastic element is in a stretched state; when the lifting plate is in the paper-discharging position, the reset elastic element is in a retracted state. The reset elastic element assists the lifting plate in entering the paper-discharging position, ensuring the lifting plate is stably positioned.

[0009] Preferably, a paper-splitting baffle is provided at the outlet of the conveyor belt. The bottom of the paper-splitting baffle has a paper-splitting inclined surface that contacts the material. The paper-splitting baffle is positioned above the conveyor belt, and there is a paper-passing gap between the paper-splitting baffle and the conveyor belt. The paper-passing gap is not less than the thickness of a single sheet of material. The paper-splitting baffle blocks the material, while the paper-passing gap allows single sheets of material to pass through, ensuring that the material is delivered one by one.

[0010] Furthermore, the paper separating baffle is adjustable left and right on a crossbeam, which has scale markings for measuring length. These markings make the adjustment more intuitive and convenient for operators.

[0011] Furthermore, the frame also includes a hopper with a left baffle and a right baffle, which are adjustable left and right on the crossbeam. The hopper can be adjusted according to the material specifications. The left and right baffles are adjusted via scale markings on the crossbeam, making the adjustment intuitive and convenient.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] The paper feeding device of the paper box forming equipment includes a frame, on which a lifting plate 1 and a conveyor belt 2 are mounted. The lifting plate 1 has a lifting surface, which is a plane that contacts the bottom of the material. The conveyor belt 2 has a conveying surface, which is a plane that rubs and feeds the material. The lifting plate 1 is positioned to the side of the conveyor belt 2. The lifting plate 1 is mounted on a rotating shaft 3, which is connected to a servo motor. The servo motor drives the lifting plate 1 to reciprocate between a lifting position and a releasing position. The lifting position is above the releasing position. The servo motor can flexibly adapt to various product specifications and has high control precision. When the lifting plate 1 is in the lifting position, the material-bearing surface of the lifting plate 1 is higher than the conveying surface of the conveyor belt 2, and the lifting plate 1 in the lifting position separates the material from the conveyor belt 2. When the lifting plate 1 is in the releasing position, the material-bearing surface of the lifting plate 1 is not higher than or intersects with the conveying surface of the conveyor belt 2, and the lifting plate 1 in the releasing position makes the bottom of the material contact the conveyor belt 2, and the conveyor belt 2 feeds the material out.

[0021] like Figure 5 As shown, the servo motor drives the lifting plate 1 to swing around the rotating shaft 3. The rotating shaft 3 causes the material-bearing surface of the lifting plate 1 to intersect with the conveying surface of the conveyor belt 2. The lifting plate 1 is fixedly mounted on the rotating shaft 3. The rotating shaft 3 drives the lifting plate 1 to swing up and down around the rotating shaft 3. The lifting surface of the lifting plate 1 is inclined to the discharge end.

[0022] like Figure 4As shown, a servo motor drives the lifting plate 1 to perform cam motion. A lifting drive assembly 4 is located between the rotating shaft 3 and the lifting plate 1. The lifting drive assembly 4 ensures that the material-bearing surface of the lifting plate 1 is not higher than the conveying surface of the conveyor belt 2. The lifting drive assembly 4 includes a mounting block 41, rollers 42, and a support shaft 43. The mounting block 41 is fixedly mounted on the rotating shaft 3. The mounting block 41 can be integral or separate; separate mounting blocks are fastened to the rotating shaft 3 with bolts. The mounting block 41 is hinged to one end of the lifting plate 1. The rollers 42 and the mounting block 41 are respectively located at both ends of the lifting plate 1. The support... Shaft 43 is correspondingly positioned below roller 42. The support shaft 43 is in contact with roller 42. The outer surface of the support shaft 43 has a guide slope 44. The roller 42 moves along the guide slope 44. The lifting drive assembly 4 drives the lifting board 1 to move up and down. When the lifting board 1 enters the paper lifting position, the roller 42 moves up along the guide slope 44. When the lifting board 1 moves towards the paper placement position, the roller 42 moves down along the guide slope 44. The guide slope 44 ensures stable lifting of the lifting board 1 and reduces shaking. At the same time, the lifting drive assembly 4 in this embodiment is relatively linear in movement, which makes installation simple and cost-effective. To ensure that the lifting plate 1 enters the paper-laying position stably, a reset elastic element 5 is also connected between the lifting plate 1 and the mounting block 41. When the lifting plate 1 is in the paper-lifting position, the reset elastic element 5 is in a stretched state; when the lifting plate 1 is in the paper-laying position, the reset elastic element 5 is in a retracted state. The reset elastic element 5 can be a tension spring or a spring. The elastic force of the reset elastic element 5 can help the lifting plate 1 stably reach the paper-laying position, ensuring the smooth operation of the equipment.

[0023] To ensure that materials are fed one by one, a paper-separating baffle 6 is provided at the outlet of the conveyor belt 2. The bottom of the paper-separating baffle 6 has a paper-separating inclined surface 61 that contacts the material. The bottom of the paper-separating baffle 6 is pointed. The paper-separating baffle 6 is positioned above the conveyor belt 2, and there is a paper-passing gap between the paper-separating baffle 6 and the conveyor belt 2. The paper-passing gap is not less than the thickness of a single sheet of material. The paper-separating inclined surface 61 of the paper-separating baffle 6 allows the material to tilt, preventing single sheets of material from sticking together. The paper-passing gap allows the material to be fed out one by one. To accommodate materials of different specifications, the paper-separating baffle 6 is adjustable left and right on the crossbeam 7. The paper-separating baffle 6 is secured to the crossbeam 7 by a first connecting block. When the paper-separating baffle 6 is adjusted to the appropriate position, the first locking block is threadedly connected to the first connecting block, securing it firmly to the crossbeam 7. The crossbeam 7 has scale markings for measuring length, which makes the adjustment more intuitive and convenient. To accommodate materials of different specifications, the frame also has a hopper 8, which has a left baffle 81 and a right baffle 82. The left baffle 81 and the right baffle 82 are respectively adjusted left and right on the crossbeam 7. The left baffle 81 and the right baffle 82 are respectively locked onto the crossbeam 7 by a second connecting block. When the left baffle 81 and the right baffle 82 are adjusted to the appropriate position, the second locking block is threadedly connected to the second connecting block, so that the two are respectively fastened on the crossbeam 7. Example 1

[0024] Before starting the machine, the material hopper 8 and the paper separating baffle 6 are adjusted according to the material specifications.

[0025] After startup, the servo motor drives the mounting block 41 to swing downwards, and the roller 42 moves downwards along the guide slope 44, moving the lifting plate 1 to the paper feeding position so that the bottom of the material contacts the conveyor belt 2. The conveyor belt 2 then carries the bottom material forward, and each sheet of material passes through the paper feeding gap below the paper separating baffle 6 to enter the next process. After the paper feeding is completed, the servo motor drives the mounting block 41 to swing upwards, and the roller 42 moves upwards, moving the lifting plate 1 to the paper lifting position. The lifting plate 1 lifts the material, separating the bottom of the material from the conveyor belt 2, and the paper feeding stops. Example 2

[0026] The specification adjustment method is the same as in Example 1. The lifting plate 1 is initially located in the paper lifting position. After the machine is turned on, the servo motor drives the lifting plate 1 to the paper feeding position. The lifting plate 1 swings downward around the rotating shaft 3, so that the bottom front half of the material contacts the conveyor belt 2. The conveyor belt 2 drives the material forward. The paper passage gap under the paper separating baffle 6 allows single sheets of material to pass through. After the paper feeding is completed, the servo motor drives the lifting plate 1 to return to the paper lifting position and stops feeding paper.
