Description

Technical Field

[0001] This utility model relates to the field of quantitative conveying technology, and in particular to a quantitative weighing and conveying device for facial tissues. Background Technology

[0002] The facial tissue quantitative weighing and conveying device is an automated equipment used in the production and processing of facial tissues. Its main function is to accurately convey and weigh facial tissues according to a set weight and quantity, ensuring the efficiency and accuracy of subsequent packaging processes. This device integrates conveying, weighing, and quantitative control, and is widely used in various paper product manufacturing enterprises. It can effectively improve production efficiency, reduce manual intervention, and ensure the consistency and standardization of product quality.

[0003] Existing facial tissue weighing and conveying systems typically consist of a conveying mechanism, a weighing mechanism, and a control system. The conveying mechanism mostly uses belt conveyors or roller conveyors to feed the facial tissues from the production line into the weighing area. The weighing mechanism is equipped with load cells that can detect the weight of the facial tissues in real time and provide feedback to the control system. The control system determines whether the required quantity has been met based on preset parameters and controls the start and stop of the conveying mechanism accordingly. The entire system combines mechanical transmission with electronic control to achieve continuous or intermittent weighing and conveying operations, adapting to the needs of different production cycles.

[0004] However, existing conveyor mechanisms have fixed structures and non-adjustable conveyor belt lengths. When dealing with facial tissue production tasks requiring different specifications or lengths, it is often necessary to customize conveyor belts of different lengths. This results in poor equipment versatility, inconvenient adjustments, increased production costs and equipment replacement cycles, and reduced production efficiency. In particular, adjusting the conveyor distance according to different product sizes is a tedious task in facial tissue production workshops, making it difficult to meet the needs of flexible production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quantitative weighing and conveying device for facial tissues, which aims to improve the problem of needing to customize the length of the conveyor belt when conveying facial tissues at different intervals in the production workshop.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a facial tissue quantitative weighing and conveying device, comprising a housing, a display screen provided on one side of the housing, a weighing sensor fixedly connected inside the housing, a conveyor belt fixedly connected to the top of the weighing sensor, a feeding roller rotatably connected to one side of the housing, and a support leg fixedly connected to the other side of the housing, wherein an adjustment component is provided inside the support leg;

[0007] The adjustment assembly includes a second support rod, which is slidably connected inside a first support rod. A motor is fixedly connected to the outer wall of the second support rod, and a rotating roller is fixedly connected to the output end of the motor.

A limit rod is fixedly connected to one side of the first support rod, and a limit roller is provided at one end of the limit rod. A reset assembly is provided inside the limit rod.

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a limiting post, both ends of which are fixedly connected to the inside of a limiting rod.

A first spring is sleeved on the outer wall of the limiting post, one end of which is fixedly connected to the inside of the limiting rod, and the other end of which is fixedly connected to one side of the slider.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes an electric push rod, one end of which is fixedly connected to one side of the second support rod, and the output end of which is fixedly connected to one side of the first support rod.

[0012] As a further description of the above technical solution:

[0013] A frame is fixedly connected to one side of the housing, and a limit roller is rotatably connected inside the frame.

[0014] As a further description of the above technical solution:

[0015] The frame is rotatably connected to a connecting rod, and one end of the connecting rod is fixedly connected to a bracket.

[0016] As a further description of the above technical solution:

[0022] The above-mentioned technical solutions of the facial tissue quantitative weighing and conveying device provided in this embodiment of the utility model have at least one of the following technical effects:

[0023] 1. In this utility model, the output end of the electric push rod first extends to drive the support rod one to extend from the support rod two, thereby adjusting the length of the conveyor strip. When the conveyor strip is lengthened or shortened, the tension of the first spring supports it, allowing the first spring to adhere to one side of the slider and drive the limit roller pair of conveyor strips to always be taut, thus achieving the effect of adjusting the length of the conveyor belt. This solves the problem of needing to customize the length of the conveyor belt when conveying facial tissues in the production workshop due to different spacing, and improves the practicality of the quantitative weighing and conveying device.

[0040] Working principle: When using this facial tissue quantitative weighing and conveying device, the length of the conveyor bar 11 needs to be adjusted first. The output end of the electric push rod 14 extends and drives the support rod 6 to extend from the support rod 7, thereby adjusting the length of the conveyor bar 11. When the conveyor bar 11 is lengthened or shortened, it is supported by the tension of the first spring 17, so that the first spring 17 can fit against one side of the slider 16 and drive the limit roller 13 to keep the conveyor bar 11 taut. Then, the output end of the motor 8 drives the rotating roller 10 to rotate and drive the conveyor bar 11 to rotate. Then, the facial tissue is conveyed to the conveyor belt 3 and weighed by the weighing sensor 9. The weight is displayed on the display screen 2. After reaching the standard, it is conveyed to the unloading roller 4 through the conveyor belt 3 for unloading, thus achieving the effect of adjusting the length of the conveyor belt 3.

[0041] Subsequently, the facial tissue is limited on the feeding roller 4 by limiting roller 2 19 and limiting roller 3 22. Limiting roller 3 22 is limited by bracket 21 and connected to frame 18 by connecting rod 20. At the same time, the other side of bracket 21 is supported by the tension of second spring 25, so that limiting roller 3 22 can always be in contact with the outer wall of facial tissue for limitation, preventing deviation during movement. Second spring 25 is connected by telescopic rod 24, and both ends are connected to bracket 21 and frame 18 by connecting block 23 for limitation, thus achieving the effect of limiting facial tissue.
