Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of workshop production and transportation equipment, specifically a lifting platform transportation equipment for corrugated cardboard pallets in a corrugated cardboard workshop. Background Technology
[0002] Currently, vertical transportation in corrugated cardboard palletizing uses freight elevators. Freight elevators are used in factories and workshops to move large machinery, heavy parts, raw materials (such as steel and sheet metal), and finished goods, realizing vertical transportation between different stages of the production line and improving production efficiency. The core purpose of hydraulic freight elevators is to solve the problem of vertical transportation of heavy and bulky goods. Their advantages are strong load-bearing capacity, high stability, and flexible adaptation to different scenarios. When selecting one, factors such as the weight of the goods, frequency of use, and installation environment (such as indoor / outdoor, temperature, and space size) should be considered, along with appropriate safety devices (such as overload protection and emergency stop buttons) and customized functions to ensure efficient and safe operation.
[0003] Although freight elevators can transport goods vertically, they require manual labor or forklifts to move the goods onto the elevator, which is inefficient. Furthermore, manual labor is required at both the bottom and top of the elevator to move the goods, which is time-consuming and labor-intensive. Repeated handling can also easily cause the corrugated cardboard stacks to tilt and collapse. In order to improve its operating efficiency and transportation convenience, this application is made. Utility Model Content
[0004] The purpose of this utility model is to provide a corrugated cardboard pallet lifting platform to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A corrugated cardboard pallet lifting platform includes a hydraulic elevator and a control terminal. The hydraulic elevator consists of a support frame, hydraulic rods, chain assemblies, and a cargo box. The support frame is composed of I-beams, and hydraulic rods and chain assemblies for vertically lifting the cargo box are respectively installed on both sides of the support frame. A palletizing component is installed at the bottom of the cargo box, and the front and back of the cargo box are open. A support rod located at the back of the cargo box is installed on the support frame. The palletizing component consists of two sets of belt conveyors, each set of belt conveyors including a left conveyor group and a right conveyor group. The left and right conveyor groups are respectively equipped with drive motors, and laser rangefinders corresponding to the left and right conveyor groups are installed on the support rods.
[0007] As a further embodiment of this utility model: the palletizing component includes a base, a mounting frame, bolts, a middle bridge, and a belt conveyor. The mounting frame is provided on the outer side of the base and is fixed to the cargo box by bolts. The middle bridge for mounting the belt conveyor is provided on the base.
[0008] As a further improvement of this utility model: two sets of belt conveyors are installed on the base, each set of belt conveyors includes a left conveyor group and a right conveyor group, and the left conveyor group and the right conveyor group are separated by a middle bridge.
[0009] As a further improvement of this utility model: the left transmission group and the right transmission group have the same structure;
[0010] The left transmission group includes a transmission belt, a roller group, and a drive motor. The roller group is rotatably mounted between the base and the middle bridge via bearings. The transmission belt is mounted on the outside of the roller group. The roller group is connected to the drive motor, which drives the transmission.
[0011] As a further embodiment of this invention: the control terminal is connected to the laser rangefinder and the drive motor electrical signal respectively, and the control terminal controls the rotation speed of the corresponding drive motor through the distance of the corrugated paper stack detected by the laser rangefinder.
[0012] As a further improvement of this utility model: the bracket is provided with a feeding port and a discharging port, and the laser rangefinder is located on the other side of the feeding port.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This corrugated cardboard pallet lifting platform uses a transfer component installed inside the cargo compartment of a hydraulic freight elevator. The transfer component automatically transfers the cardboard through a conveyor belt. After the transfer is completed, the hydraulic rod drives the cargo compartment via a chain assembly to transport the corrugated cardboard vertically upwards. Once at the top, the transfer component uses the rotation of the conveyor belt to send the corrugated cardboard to the next process. This method effectively improves the automation level of the equipment, eliminating the need for manual or forklift handling.
[0015] 2. This corrugated cardboard pallet lifting platform uses a belt conveyor to transport corrugated cardboard in two separate conveyor belts. Under normal transport conditions, the two conveyor belts rotate synchronously to transport the corrugated cardboard. When the laser rangefinder detects that the distance difference between the two sides of the corrugated cardboard is too large, the corresponding conveyor belt drive motor is adjusted through the control terminal. The position of the corrugated cardboard is adjusted by the speed difference generated by the motor driving the conveyor belt. Attached Figure Description

Detailed Implementation
[0021] Please see Figures 1-4 In this embodiment of the utility model, a corrugated cardboard pallet lifting platform includes a hydraulic elevator and a control terminal. The hydraulic elevator consists of a support frame 1, hydraulic rods 5, chain assembly 6, and a cargo box 4. The support frame 1 is composed of I-beams. Hydraulic rods 5 and chain assembly 6 for vertical lifting of the cargo box 4 are respectively provided on both sides of the support frame 1. A transfer component 7 is installed at the bottom of the cargo box 4. The front and back of the cargo box 4 are open. A support rod 9 located on the back of the cargo box 4 is installed on the support frame 1. The transfer component 7 consists of two sets of belt conveyors. Each set of belt conveyors includes a left transmission group 705 and a right transmission group 706. The left transmission group 705 and the right transmission group 706 are respectively equipped with drive motors 7053. A corresponding device is installed on the support rod 9 for the left transmission group 705 and the right transmission group 706. The laser rangefinder sensor 8 and the bracket 1 are equipped with a loading port 2 and a unloading port 3. The laser rangefinder sensor 8 is located on the other side of the loading port 2. Corrugated cardboard is stacked on a pallet and transported to the loading port 2 of the hydraulic elevator by a conveyor belt or a rail trolley. The position of the rail trolley is collected by the environmental sensor of the rail trolley. After the rail trolley is in place, the conveyor belt of the rail trolley and the transfer component 7 rotate synchronously and at the same frequency. The material moves to the transfer component 7 under the action of the conveyor belt. After the transfer is completed, the hydraulic rod 5 drives the cargo box 4 through the chain group 6 to transport the corrugated cardboard vertically upward. After being placed at the top, the transfer component 7 sends the corrugated cardboard to the top conveyor belt through the rotation of the conveyor belt to the next process. This method can effectively improve the automation level of the equipment and eliminate the need for manual or forklift handling.
[0022] In a preferred embodiment, the transfer component 7 includes a base 701, a mounting frame 702, bolts 703, a central bridge 704, and a belt conveyor. The mounting frame 702 is provided on the outer side of the base 701 and is fixed to the cargo box 4 by bolts 703. The central bridge 704 for mounting the belt conveyor is provided on the base 701. The transfer component 7 is detachable and is powered by a cable. The cable can be fixed to the bracket 1 by a cable chain to provide power while protecting the cable. The transfer component 7 is detachable and its arrangement height is flush with the corrugated cardboard conveyor belt.
[0023] In a preferred embodiment, two sets of belt conveyors are installed on the base 701. Each set of belt conveyors includes a left conveyor group 705 and a right conveyor group 706, which are separated by a middle bridge 704. The middle bridge 704 serves as a support carrier between the left conveyor group 705 and the right conveyor group 706.
[0024] In a preferred embodiment, the left transmission group 705 and the right transmission group 706 have the same structure;
[0025] The left conveyor group 705 includes a conveyor belt 7051, a roller group 7052, and a drive motor 7053. The roller group 7052 is rotatably mounted between the base 701 and the middle bridge 704 via bearings. The conveyor belt 7051 is mounted on the outside of the roller group 7052. The roller group 7052 is connected to the drive motor 7053, which drives the conveyor. The drive motor 7053 is a variable frequency motor with controllable speed. The drive motor 7053 configured in the left conveyor group 705 is labeled as drive motor a, and the drive motor 7053 configured in the right conveyor group 706 is labeled as drive motor b. Drive motor a and drive motor b are controlled by a motor synchronization system. During the transfer process, the corrugated cardboard moves simultaneously onto the left conveyor group 705 and the right conveyor group 706.
[0026] In a preferred embodiment, the control terminal is electrically connected to the laser rangefinder 8 and the drive motor 7053, respectively. The control terminal controls the rotation speed of the corresponding drive motor 7053 based on the distance of the corrugated cardboard stack detected by the laser rangefinder 8. During the corrugated cardboard transfer process, the different friction forces with the belt during contact can cause the corrugated cardboard to tilt, leading to tipping and collapse during the next transfer, resulting in unstable corrugated cardboard conveying. To solve the problem of tilting and offset during the corrugated cardboard transfer process caused by friction, this application adds laser rangefinders a and b corresponding to drive motors a and b, respectively. The laser rangefinders a and b detect the distance between the two sides of the corrugated cardboard. When the distance difference is large, it indicates that the corrugated cardboard has shifted during transfer. The control terminal controls the drive motor on the side with the larger distance to increase its speed, creating a speed difference between the left transmission group 705 and the right transmission group 706, thus adjusting the position of the corrugated cardboard. At the same time, the laser rangefinder can also detect the transfer status of the corrugated cardboard and determine whether the transfer is complete.
[0027] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.
[0028] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 patent should be determined by the appended claims.
