Abstract
Description
Technical Field
[0001] This utility model relates to the field of hand towel technology, specifically a hand towel neat positioning and conveying device. Background Technology
[0002] Hand towels inevitably require conveyor belts for transport during both production and folding processes. Due to their thin and lightweight nature, hand towels are easily affected by ambient natural ventilation, workshop ventilation, and the movement of pedestrians or vehicles. This can cause minor issues like towels shifting on the conveyor, affecting their neatness and accuracy, leading to misalignment during subsequent folding and packaging, and impacting product appearance. In more serious cases, they may even fall off the conveyor, becoming contaminated and unusable, resulting in unnecessary losses and waste. Therefore, our company has designed and proposed a targeted hand towel alignment and positioning conveyor device. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a neat and orderly positioning and conveying device for hand towels, which is used to achieve the purpose of neatly positioning and conveying lightweight hand towels.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] A hand towel neat positioning and conveying device includes two sets of conveyor rollers and a conveyor belt installed between the two sets of conveyor rollers. The conveyor belt is evenly provided with vertically penetrating ventilation slots. A negative pressure air trough with an open top is provided below the upper surface of the conveyor belt. A support roller supporting the conveyor belt is installed in the negative pressure air trough and is supported below the upper surface of the conveyor belt. Multiple longitudinal partitions are fixed at equal intervals along the length of the conveyor belt in the negative pressure air trough. Negative pressure pipes are installed at equal intervals at the bottom of the negative pressure air trough. The negative pressure pipes are connected to a negative pressure fan through connecting pipes.
[0006] Preferably, the ventilation seam is straight and is arranged along the length of the conveyor belt.
[0007] Preferably, the front panel and back panel of the negative pressure air duct extend upwards and are movably engaged with the upper surface of the conveyor belt. The longitudinal partition and the side panel of the negative pressure air duct are all left with gaps so as not to contact the upper surface of the conveyor belt. The distance between the side panel of the negative pressure air duct and the upper surface of the conveyor belt is not greater than the distance between the longitudinal partition and the upper surface of the conveyor belt.
[0008] Preferably, the support rollers are multiple and equidistantly supported below the upper surface of the conveyor belt.
[0009] Preferably, the connecting pipe includes a connecting pipe disposed between adjacent negative pressure pipes, a manifold disposed between the connecting pipe and the negative pressure fan, and a pipe joint disposed between the connecting pipe and the negative pressure pipe and between the connecting pipe and the manifold.
[0010] Preferably, the manifold is connected to the connecting pipe at the middle position, and is connected to the middle position of the corresponding connecting pipe through a pipe fitting.
[0011] Preferably, a bucket-shaped adapter is installed between the manifold and the negative pressure fan.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention features a negative pressure trough below the upper surface of a conveyor belt. A negative pressure fan is connected to generate negative pressure between the trough and the upper surface of the conveyor belt. The conveyor belt has evenly spaced ventilation seams. Hand towels neatly placed on the conveyor belt are fixed to the upper surface of the belt due to the negative pressure from the ventilation seams, preventing them from shifting or being blown off by the wind. This achieves the effect of neatly positioning and conveying the hand towels. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-4As shown, this utility model provides a technical solution: a neat positioning and conveying device for hand towels, including two sets of conveying rollers 1 and a conveyor belt 2 installed between the two sets of conveying rollers 1. The conveyor belt 2 is evenly provided with vertically penetrating ventilation slots 3. The ventilation slots 3 are straight and are arranged along the length direction of the conveyor belt 2 to adapt to the tension direction of the conveyor belt 2, so as to avoid the conveyor belt 2 being pulled and damaged at the ventilation slots 3.
[0021] A negative pressure duct 4 with an open top is provided below the upper surface of the conveyor belt 2. Support rollers 5 are installed in the negative pressure duct 4 and are supported below the upper surface of the conveyor belt 2. There are multiple support rollers 5 and they are equidistantly supported below the upper surface of the conveyor belt 2. Multiple longitudinal partitions 6 are fixed equidistantly along the length of the conveyor belt 2 in the negative pressure duct 4. Negative pressure pipes 7 are installed equidistantly at the bottom of the negative pressure duct 4. The negative pressure pipes 7 are connected to the negative pressure fan 9 through connecting pipes 8.
[0022] The connecting pipe 8 includes a connecting pipe 801 disposed between adjacent negative pressure pipes 7, a manifold 802 disposed between the connecting pipe 801 and the negative pressure fan 9, and a pipe joint 803 disposed between the connecting pipe 801 and the negative pressure pipe 7 and between the connecting pipe 801 and the manifold 802. The manifold 802 is connected to the connecting pipe 801 in the middle position, and is connected to the middle position of the corresponding connecting pipe 801 through the pipe joint 803 to achieve a uniform negative pressure effect. A bucket-shaped adapter 10 is installed between the manifold 802 and the negative pressure fan 9.
[0023] The front panel and back panel of the negative pressure air duct 4 extend upwards and are movably engaged with the upper surface of the conveyor belt 2. The longitudinal partition 6 and the side panel of the negative pressure air duct 4 are all left with gaps and do not contact the upper surface of the conveyor belt 2. The distance between the side panel of the negative pressure air duct 4 and the upper surface of the conveyor belt 2 is not greater than the distance between the longitudinal partition 6 and the upper surface of the conveyor belt 2.
[0024] Working principle:
[0025] Initially, the hand towels are neatly placed on the conveyor belt 2. After the negative pressure fan 9 is turned on, negative pressure is generated between the negative pressure air duct 4 connected to it and the upper surface of the conveyor belt 2. The conveyor belt 2 is evenly provided with ventilation seams 3, so that the hand towels are pressed onto the upper surface of the conveyor belt 2 by atmospheric pressure, ensuring that the hand towels are neatly positioned and conveyed when the conveyor belt 2 is running.
