Description

Technical Field

[0001] The utility model belongs to the technical field of material tray conveying, and in particular relates to a device for vertically lifting a material tray. Background Art

[0002] A tray is an object used to store materials. Usually, the tray is transported by a conveyor belt to transport the material from one location to another, completing the automatic transportation of the material. However, when the material needs to be changed in height, in order to reduce the transportation space, a vertical lifting method is usually used to complete the transportation of the material.

[0003] In the prior art, materials are usually transported vertically by means of chain conveyors, elevators, cylinders, etc. However, during the transportation process, when the materials are moved upward, it is necessary to overcome the gravity of the materials themselves and the force driving the materials to rise. When the materials are lowered, it is also necessary to provide support force for the materials to ensure smooth transportation of the materials. At the same time, during the transportation process, the materials can only be transported again after being lowered and placed on the materials. This has low efficiency and requires a large driving force. Utility Model Content

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A device for vertically lifting a material tray, comprises two lifting plates and two mounting frames, the lifting plates are slidably connected to the mounting frames, a cylinder is assembled and connected to the lower side of one of the lifting plates, a material tray is placed on the upper side of the lifting plate, a rotating support assembly is assembled and connected between the two mounting frames, the rotating support assembly is located on the top of the mounting frame, a steel rope is connected between the two lifting plates, the two ends of the steel rope are respectively fixedly connected to the upper inner side of the lifting plate, the inner side of the steel rope is slidably connected to the rotating support assembly, a high and a low conveying mechanism are respectively provided on the front and rear sides of the lifting plate, and the two conveying mechanisms are respectively flush with the two working surfaces of the lifting plate.

[0013] The utility model is cleverly designed. It realizes the lifting and lowering of two lifting plates by one cylinder, while reducing the force required by the cylinder to lift the lifting plates. When one lifting plate rises, the other lifting plate descends. The descending lifting plate provides an upward force to the ascending lifting plate, reducing the lifting force of the cylinder. When the other lifting plate rises, the driving force of the descending lifting plate driven by the cylinder and the gravity of the self-lifting of the lifting plate drive the other lifting plate to rise. This has higher efficiency in lifting the material tray and saves more energy.

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-5 As shown, a device for vertically lifting a material tray includes two lifting plates 1 and two mounting frames 2, the lifting plates 1 are slidably connected to the mounting frames 2, a cylinder 3 is assembled and connected to the lower side of one lifting plate 1, a material tray 11 is placed on the upper side of the lifting plate 1, a rotating support assembly 4 is assembled and connected between the two mounting frames 2, the rotating support assembly 4 is located on the top of the mounting frames 2, a steel rope 5 is connected between the two lifting plates 1, both ends of the steel rope 5 are respectively fixedly connected to the upper inner side of the lifting plate 1, the inner side of the steel rope 5 is slidably connected to the rotating support assembly 4, and a high and a low conveying mechanism are respectively provided on the front and rear sides of the lifting plate 1, and the two conveying mechanisms are respectively flush with the two working surfaces of the lifting plate 1.

[0029] The technical solution of this embodiment is adopted, and the lifting plate 1 moves vertically on the mounting frame 2. One lifting plate 1 is controlled to move up and down by the cylinder 3, and the other lifting plate 1 moves up and down under the traction of the steel rope 5. When the lifting plate 1 connected to the cylinder 3 rises, since the length of the steel rope 5 is fixed and it is in a stretched state under the pulling of the two lifting plates 1, the other lifting plate 1 falls under the action of its own gravity. When the lifting plate 1 connected to the cylinder 3 falls, the other lifting plate 1 rises under the traction of the steel rope 5, thereby realizing the lifting and lowering of the material by the lifting plate. The conveying mechanism is used to convey the material tray 11, and conveys the material tray to the lifting plate 1, and then it is lifted by the lifting plate 1. The steel rope 5 is wound from above the rotating support assembly 4, and the rotating support assembly 4 supports the steel rope 5 and can rotate at the same time, converting the sliding friction between the steel rope 5 and the rotating support assembly 4 into rolling friction, reducing the friction on the steel rope 5 and extending the service life of the steel rope 5.

[0030] Reference Figure 2-5The rotating support assembly 4 includes a rotating rod 41, a mounting seat 42, two rotating sleeves 43 and two connecting rods 44. The mounting seat 42 is fixedly connected to the upper inner side of the two mounting frames 2. The two connecting rods 44 are fixedly connected to the mounting seats 42 on the front and rear sides respectively. The rotating rod 41 is rotatably connected between the two rotating sleeves 43, and the rotating sleeves 43 are fixedly connected to the connecting rods 44.

[0031] Reference Figure 5 : There are two steel ropes 5, and the rotating rod 41 is fixedly connected to the limiting ring 412 inside the two steel ropes 5.

[0032] In this embodiment, the two steel ropes 5 are used to make the force on the lifting plate 1 more balanced, reduce the stress at the connection between the steel ropes 5 and the lifting plate 1, and make the movement of the lifting plate 1 more stable. The limit ring 412 is used to prevent the steel ropes 5 from shifting during the sliding process.

[0033] Reference Figure 1 The conveying mechanism includes a conveying frame 61 and a conveying belt 62. The conveying frame 61 is assembled and connected to the conveying belt 62. Two telescopic cylinders 63 are assembled and connected to the outer side of the conveying frame 61. The output end of the telescopic cylinder 63 is assembled and connected to a push plate 64. The two telescopic cylinders 63 are respectively aligned with the middle of the lifting plate 1.

[0034] Reference Figure 1 : The push plate 64 of the telescopic cylinder 63, which is located at the rear side of the lifting plate 1 and is assembled and connected to the conveying frame 61, is assembled and connected with an electromagnet plate 641, and the material tray 11 is made of iron.

[0035] In this embodiment, the electromagnet plate 641 is used to adsorb the material tray 11, and the operation of the telescopic cylinder 63 is controlled by a program. When the lifting plate 1 aligned with the telescopic cylinder 63 rises to a position horizontal to the conveyor belt, the push plate 64 of the telescopic cylinder 63 extends out and contacts the material tray 11. While contacting the material tray 11, the electromagnet plate 641 is energized to adsorb the material tray 11, and then the push plate 64 is retracted to transport the material tray 11 to the conveyor belt. Then the electromagnet plate 641 is de-energized, and the conveyor belt transports the material tray 11.

[0036] Reference Figure 3 : A vertically arranged rib 7 is provided on the upper side of the lifting plate 1, and a rib groove matching the rib 7 is provided on the lower side of the material tray 11.

[0037] In this embodiment, the ribs 7 are used to limit the material tray to prevent the material tray 11 from moving, while also not affecting the control of the material tray 11 by the telescopic cylinder 63 .

[0038] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
