Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a pressing device and a belt conveyor. Background Technology

[0002] A conveyor is a mechanical device used for continuous or intermittent material transportation. It is widely used in industries such as industry, logistics, mining, and agriculture. The emergence of conveyors has greatly reduced the intensity of manual labor, improved transportation efficiency, and adapted to the needs of various materials such as bulk materials, block materials, and powder materials. It is a core piece of equipment for modern production automation and efficient logistics. However, when conveying long strip raw materials to a high position, it is difficult to load them manually. Therefore, a pressing device and a belt conveyor are proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to manually feed long strips of raw materials when conveying them to a higher position. This invention provides a pressing device and a belt conveyor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pressing device includes a pressing assembly disposed on the top of a frame. The pressing assembly includes two guide rails, both of which are fixed to the top of the frame. A slider is slidably connected in each of the two guide rails. A through-shaft is rotatably connected to one side of each slider. A rotating frame is fixedly connected to the opposite side of each rotating shaft. The rotating frame is obliquely downward. Three pressure rollers are rotatably connected between the two rotating frames. A pressure belt is drivenly connected between the three pressure rollers. Two of the pressure rollers are located on the same horizontal line so that one side of the pressure belt is inclined.

[0006] Each slider has a guide rod fixedly connected to its top, and the guide rod slides through the top of the guide rail. A first spring is fixedly connected between the slider and the guide rail, and a torsion spring is fixedly connected between the rotating shaft and the slider.

[0007] As a further embodiment of this utility model, a U-shaped drive frame is rotatably connected between the two sides of the frame, and a connecting rod is rotatably connected between the two sides of the drive frame and the two sides of the rotating frame.

[0008] As a further improvement of this invention, a sponge pad is adhered to one side of the drive frame.

[0009] This utility model also proposes a belt conveyor, including a pressing device and multiple conveying rollers, which rotate between the two sides of the frame. A conveyor belt is connected between the multiple conveying rollers, and one side of the conveyor belt is inclined to cooperate with the pressing belt to press and convey the raw material.

[0010] It also includes a tensioning mechanism, which is disposed between the two sides of the frame for tensioning the conveyor belt.

[0011] As a further embodiment of this invention, a plurality of support rollers for supporting and guiding the conveyor belt are rotatably connected between the two sides of the frame.

[0012] As a further embodiment of this utility model, a motor is fixedly connected to one side of the frame, and one end of the motor output shaft is fixed to one of the conveying rollers located at the end.

[0013] As a further embodiment of this utility model, the tensioning mechanism includes two sliding frames, which slide through both sides of the frame. The bottom of each sliding frame is fixedly connected to a fixed seat, and a tensioning roller is rotatably connected between the two fixed seats. The conveyor belt passes over the bottom of the tensioning roller, and a second spring is fixedly connected between the fixed seat and the frame.

[0014] As a further improvement of this invention, a slag collection box is provided on one side of the frame for collecting falling material.

[0015] In this application, when material needs to be fed, the motor is started. The motor drives the conveyor belt to rotate through multiple conveyor rollers, lifting the drive frame upward. Then, the long strip of cloth-like material is placed between the pressure belt and the conveyor belt. The torsion spring keeps the pressure belt in contact with the material and presses it down. In turn, it works with the conveyor belt to guide the material obliquely upward, allowing the material to enter above the conveyor rollers. The slider and the first spring ensure that the rotating frame has good displacement space, preventing local material accumulation that could cause deformation of the conveyor belt or conveyor rollers. During the conveying process, as the conveyor belt transports the material, the tension roller moves with the force applied to the conveyor belt, thereby maintaining the stability of the conveyor belt tension, ensuring stable material transport, and improving the service life of the device.

[0016] Beneficial effects: In this utility model, the pressing device and belt conveyor, by installing a pressing belt above the conveyor belt, enable the material to be pressed onto the conveyor belt during the material conveying process, thereby conveying the material obliquely upward and reducing the difficulty of material feeding;

[0017] In this utility model, the pressing device and belt conveyor, through the setting of the tensioning mechanism, enable the tensioning roller to move with the force of the conveyor belt during the conveying of materials, thereby maintaining the stability of the conveyor belt tension, maintaining the stability of material conveying, and improving the service life of the device.

[0018] In this invention, during the material conveying process, the material can be pressed onto the conveyor belt by the pressure belt, thereby conveying the material obliquely upward, reducing the difficulty of material feeding. At the same time, the tension roller can move with the force on the conveyor belt, thereby maintaining the stability of the conveyor belt tension, maintaining the stability of material conveying, and improving the service life of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figures 1-3 A pressing device includes a pressing assembly 8 disposed on the top of a frame 1. The pressing assembly 8 includes two guide rails 12, both of which are fixed to the top of the frame 1. A slider 15 is slidably connected in each of the two guide rails 12. A through rotating shaft 10 is rotatably connected to one side of each slider 15. A rotating frame 9 is fixedly connected to the opposite side of each rotating shaft 10. The rotating frame 9 is obliquely downward. Three pressure rollers 11 are rotatably connected between the two rotating frames 9. A pressure belt 17 is drively connected between the three pressure rollers 11. The two pressure rollers 11 are located on the same horizontal line so that one side of the pressure belt 17 is obliquely set. The obliquely set pressure belt 17 can cooperate with the conveyor to obliquely convey the raw material below upward, thereby reducing the difficulty for workers to feed the material.

[0025] The pressure roller 11 can be designed in various shapes according to the characteristics of the material: 1. Cylindrical pressure roller: suitable for uniform pressing of conventional flat materials (such as cloth and board); 2. Conical pressure roller (diameter gradually decreases at both ends): can guide the material to be conveyed in the center and prevent long strip materials from deviating.

[0026] Guide rods 13 are fixedly connected to the top of each slider 15. The guide rods 13 slide through the top of the guide rail 12. A first spring 14 is fixedly connected between the slider 15 and the guide rail 12. A torsion spring 16 is fixedly connected between the rotating shaft 10 and the slider 15. The arrangement of the slider 15 and the first spring 14 can maintain the rotating frame 9 with good displacement space, improve the flexibility of use, and avoid local material accumulation that could cause the conveyor to deform.

[0027] Example 2, Reference Figures 1-3 An improved pressing device is proposed based on Example 1.

[0028] In this invention, a U-shaped drive frame 18 is rotatably connected between the two sides of the frame 1. A connecting rod 19 is rotatably connected between the two sides of the drive frame 18 and the two sides of the rotating frame 9. Lifting the drive frame 18 upwards can drive the pressing assembly 8 to rotate upwards, which is convenient for the operator.

[0029] In particular, a sponge pad is attached to one side of the drive frame 18, which makes it easier for people to rotate the drive frame 18.

[0030] This utility model also proposes a belt conveyor, including a pressing device and multiple conveying rollers 2. The multiple conveying rollers 2 rotate between the two sides of the frame 1. The multiple conveying rollers 2 are connected by a conveyor belt 3. One side of the conveyor belt 3 is inclined and cooperates with the pressing belt 17 to press and convey the raw material.

[0031] It also includes a tensioning mechanism 6, which is disposed between the two sides of the frame 1 for tensioning the conveyor belt 3.

[0032] In this invention, multiple support rollers 5 are rotatably connected between the two sides of the frame 1 to support and guide the conveyor belt 3. The support rollers 5 prevent the excessively long conveyor belt 3 from falling.

[0033] In particular, a motor 4 is fixedly connected to one side of the frame 1. One end of the output shaft of the motor 4 is fixed to one of the conveyor rollers 2 located at the end. When the motor 4 is started, the motor 4 drives the conveyor belt 3 to rotate through multiple conveyor rollers 2.

[0034] It should be noted that the tensioning mechanism 6 includes two sliding frames 23, which slide through both sides of the frame 1. The bottom of each sliding frame 23 is fixedly connected to a fixed seat 21. A tensioning roller 20 is rotatably connected between the two fixed seats 21. The conveyor belt 3 passes over the bottom of the tensioning roller 20. A second spring 22 is fixedly connected between the fixed seat 21 and the frame 1. During the process of conveying materials by the conveyor belt 3, the tensioning roller 20 moves with the force applied to the conveyor belt 3, thereby maintaining the stability of the tension of the conveyor belt 3, maintaining the stability of material conveying, and improving the service life of the device.

[0035] In this utility model, a slag collection box 7 is provided on one side of the frame 1 for collecting falling materials and can also collect broken materials.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of motor 4 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
