Description

Technical Field

[0001] This utility model relates to an automatic centering and weighing device for straw bales, belonging to the technical field of papermaking equipment. Background Technology

[0002] Straw papermaking mainly includes steps such as straw raw material pretreatment, pulping, bleaching, papermaking, and drying. Among these steps, the straw raw material pretreatment process requires accurate weighing of loose materials of varying sizes, such as straw bales, using belt scales.

[0003] To ensure accurate weighing of straw bales by the belt scale, a centering mechanism is required. This mechanism aligns the straw bales onto the effective weighing section of the belt scale. Centering also ensures the smooth operation of the subsequent rope-cutting process.

[0004] Existing centering mechanisms mostly use fixed baffles. The fixed centering channel cannot handle straw bales of different sizes and irregular shapes, resulting in poor centering effect. It also has the problem of poor adjustability and flexibility. Every time a straw bale size is changed, the machine needs to be stopped for mechanical adjustment, or even parts need to be replaced, which is quite cumbersome.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing an automatic straw bale centering and weighing device, which can achieve continuous centering of straw bales, has high centering efficiency, is flexible in terms of straw bale size requirements, has strong adaptability, and can ensure weighing accuracy.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: An automatic centering and weighing device for straw bales includes a frame, a weighing belt installed inside the frame, and two centering mechanisms symmetrically arranged on the left and right sides above the weighing belt. Each centering mechanism includes a roller line composed of multiple rollers arranged in a row. The roller lines of the two centering mechanisms are arranged in a tapering shape along the conveying direction of the weighing belt, forming a clamping and conveying space that is wider at one end and narrower at the other. The rollers are rotatably mounted inside a push-pull plate, which is fixedly connected to a push-pull arm through at least two connectors. The side of the push-pull arm away from the push-pull plate is connected to a telescopic cylinder and a guide rod.

[0008] Furthermore, the centerline of the roller is set in the vertical direction.

[0009] Furthermore, the push-pull plate has a U-shaped structure with the U-shaped opening set in the horizontal direction, and the two ends of the roller rotate at the U-shaped opening.

[0010] Furthermore, the push-pull arm is made of aluminum alloy profile.

[0011] Furthermore, the connector consists of two U-shaped plates arranged in opposite directions, one U-shaped plate being fastened to the push-pull plate and the other U-shaped plate being fastened to the push-pull arm.

[0012] Furthermore, the connector is fixedly connected to the push-pull plate and push-pull arm by bolts.

[0013] Furthermore, the guide rods are distributed parallel to each other on both sides of the telescopic cylinder.

[0014] Furthermore, the cylinder body of the telescopic cylinder is fixedly installed in the fixed base.

[0015] Furthermore, the guide rod passes through the guide seat, and the guide seat is fixedly installed in the fixed seat.

[0016] Furthermore, the mounting base is installed on the top of the frame.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By integrating the centering and weighing processes into one station and completing them simultaneously, the straw bales can complete centering and weight collection while in motion without stopping, realizing continuous material processing and greatly improving the efficiency of centering and weight collection. By using the V-shaped channel for forced centering, it is ensured that each straw bale is centered on the weighing belt when it arrives at the weighing section, which fundamentally eliminates the weighing error caused by positional deviation and ensures the accuracy of the data. The centering mechanism on both sides is driven by a telescopic cylinder to move towards or away from each other, easily adjusting the width of the V-shaped channel to accommodate various sizes of straw bales, making it highly adaptable.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figures 1-5 As shown in the figure, this utility model provides an automatic centering and weighing device for straw bales, including a frame 1, a weighing belt 2 installed inside the frame 1, and two centering mechanisms 3 symmetrically arranged on the left and right sides above the weighing belt 2, with the centering mechanisms 3 installed on the top of the frame 1.

[0023] The centering mechanism 3 includes a roller line, which is composed of multiple rollers 31 arranged in a row, with the center line of the rollers 31 arranged in a vertical direction.

[0024] The rollers of the two centering mechanisms 3 are arranged in a tapering manner along the conveying direction of the weighing belt 2, forming a clamping and conveying space that is wider at one end and narrower at the other. The rollers of the two centering mechanisms 3 can move towards or away from each other to adjust the width of the clamping and conveying space. The straw bale 4 automatically centers itself as it travels within the clamping and conveying space. The width of the clamping and conveying space can be adjusted to accommodate the automatic centering of straw bales 4 of different volumes.

[0025] The roller 31 is rotatably installed inside the push-pull plate 32, which has a U-shaped structure with the U-shaped opening set in the horizontal direction. The two ends of the roller 31 rotate at the U-shaped opening.

[0026] The push-pull plate 32 is fixedly connected to the push-pull arm 34 by at least two connectors 33, and the push-pull arm 34 is made of aluminum alloy profile.

[0027] The connector 33 consists of two U-shaped plates arranged in opposite directions. One U-shaped plate is fastened to the push-pull plate 32, and the other U-shaped plate is fastened to the push-pull arm 34. The connector 33 is fixedly connected to the push-pull plate 32 and the push-pull arm 34 by bolts.

[0028] The side of the push-pull arm 34 furthest from the push-pull plate 32 is connected to the telescopic cylinder 36 and the guide rod 37, which are distributed parallel to each other on both sides of the telescopic cylinder 36. The telescopic cylinder 36 provides power for the movement of the push-pull arm 34, and the guide rod 37 provides guidance for the movement of the push-pull arm 34.

[0029] The cylinder body of the telescopic cylinder 36 is fixedly installed in the fixed base 35.

[0030] The guide rod 37 passes through the guide seat 38, and the guide seat 38 is fixedly installed in the fixed seat 35.

[0031] The mounting base 35 is installed on the top of the frame 1.

[0032] The specific working principle of this utility model is as follows: Preset width: Based on the specifications of the straw bale 4 to be processed, the distance between the centering mechanisms 3 on both sides is adjusted by the telescopic cylinder 36 to form a V-shaped channel of appropriate size; Material feeding: Straw bales 4 are fed into the wide end of the centering mechanism 4 by the front conveyor equipment; Automatic centering: Under the conveying of the weighing belt 2, the straw bale 4 moves in the V-shaped roller channel and is automatically corrected to the center position; Synchronous weighing: When the straw bale after centering moves to the effective weighing section of the weighing belt 2, the system collects weight data; Output materials: The straw bales 4, after being centered and weighed, are conveyed by the weighing belt 2 and then proceed to the subsequent rope cutting and unpacking process.
