Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production line opening machine technology, and more specifically to a rapid fiber cleaning device for the bottom of the opening machine. Background Technology

[0002] The unpacking machine is a key piece of equipment on the nonwoven fabric production line. It is mainly used to process fiber raw materials in the initial stage. Its core function is to loosen and initially mix the compressed fiber raw materials.

[0003] Its working principle is as follows: Figure 1 As shown, the corner nail curtain 3 is wound around the transmission roller 2. The fiber raw material 20 is manually placed on the flat curtain 10, fed in through the flat curtain 10, and then gripped by the corner nail curtain 3, initially loosened, and evenly lifted. The weighing mechanism then weighs and feeds the material according to the product's required proportions. The performance of the unpacking machine directly affects the quality and production efficiency of the nonwoven fabric.

[0004] Because the nonwoven fabric production line produces nonwoven fabrics of different colors or specifications, when changing the fiber color or type, it is necessary to clean the residual fibers between the corner nail curtain 3 and the bottom 1 of the opening machine, and then put the new fiber raw materials into the flat curtain 10 of the opening machine.

[0005] Currently, there are two main methods for cleaning residual fibers between the corner nail curtain 3 and the bottom slat 1:

[0006] One method involves setting multiple movable doors at the bottom of the slotted box. When residual fibers need to be cleaned, these doors are opened. However, this method has certain drawbacks. Operators need to enter the bottom of the box opener, and due to the limited space at the bottom of the box opener, cleaning becomes difficult and work efficiency is low.

[0007] Another method involves installing a cleaning port on the upper part of the wall panel corresponding to the drain hole. The drawback is that it can only clean residual fibers close to the cleaning port, leaving fibers further away unattended. This increases the workload for operators and the downtime of the nonwoven machinery, ultimately leading to problems such as high operator workload and low machinery efficiency. Utility Model Content

[0008] 1. Technical problem to be solved by the utility model

[0009] To address the aforementioned problems in cleaning residual fibers from the opening machine of existing nonwoven fabric production lines, this utility model provides a rapid fiber cleaning device for the bottom of the opening machine. The device features a completely redesigned bottom, eliminating the need for operators to enter the bottom of the machine. It quickly and thoroughly removes residual fibers between the corner nail curtain and the bottom of the opening machine, reducing the labor intensity of operators and improving the working efficiency of nonwoven machinery.

[0010] 2. Technical Solution

[0011] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0012] A rapid fiber cleaning device for the bottom of a bag opener includes a wall panel and a rear baffle, both fixed to the bottom of the bag opener, with the two wall panels symmetrically arranged on both sides of the bottom of the bottom. The rear baffle is connected to the inner wall of the wall panel, and its bottom end is sealed to the bottom of the bottom. An air blowing mechanism is fixed to the bottom of the rear baffle, blowing air into the gap between the bottom of the bottom and the corner nail curtain. The air blowing mechanism is connected to a high-pressure air source, which disperses the residual fibers in the gap between the corner nail curtain and the bottom of the bottom, thereby hanging the fibers on the corner nail curtain. The corner nail curtain is driven by a transmission roller, which then carries all the residual fibers out, completing the cleaning of residual fibers between the corner nail curtain and the bottom of the bottom.

[0013] Further, the bag-opening machine has a rapid fiber cleaning device for the bottom of the leak. The air blowing mechanism includes an air distribution pipe that is horizontally fixed to the bottom of the rear baffle and air blowing holes opened on the air distribution pipe. The air blowing holes are multiple evenly distributed and face the gap between the bottom of the leak and the corner nail curtain. The air distribution pipe is connected to a high-pressure air source, usually compressed air, through a connecting pipe.

[0014] Further, the packaging machine has a quick-cleaning device for the inner fibers of the leaking bottom. A pressure regulating valve and a switching valve are fixedly connected to the side of the wall panel. The high-pressure air source is connected to the pressure regulating valve, the switching valve, the quick-connect fitting and the connecting pipe in sequence through the air pipe, so that the blowing pressure of the compressed air is controllable.

[0015] Further, a rapid fiber cleaning device is added to the bottom of the packaging machine. The gap between the bottom and the corner nail curtain is 2-12mm, which is adjusted by adjusting the upper and lower positions of the transmission rollers.

[0016] Further, the bag-opening machine has a rapid fiber cleaning device for the bottom of the bag, with an air blowing hole diameter of 2-3mm and a distance of 65-80mm between adjacent holes.

[0017] Further, a rapid fiber cleaning device is added to the bottom of the packaging machine. The bottom and the rear baffle are sealed together between the left and right wall panels to avoid loss of air pressure.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model discloses a rapid fiber cleaning device for the bottom of a packaging machine. When it is necessary to clean residual fibers between the corner nail curtain and the bottom of the packaging machine, the pressure regulating valve is opened. Compressed air passes sequentially through the pressure regulating valve, the switch valve, the quick-connect connector, and the connecting pipe, entering the air distribution pipe and then being blown out from multiple air blowing holes. The blown compressed air disperses the residual fibers between the corner nail curtain and the bottom of the packaging machine, causing the fibers to hang on the corner nail curtain. Through the rotation of the corner nail curtain, all these residual fibers are carried out, completing the cleaning of residual fibers between the corner nail curtain and the bottom of the packaging machine. This reduces the labor intensity of operators, saves cleaning time, and improves the working efficiency of nonwoven machinery. Attached Figure Description

Detailed Implementation

[0028] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0029] Example 1

[0030] The rapid cleaning device for the inner fibers of the packaging machine's bottom hole in this embodiment, such as... Figure 2 , 3As shown in Figures 4, 5, and 6, the machine includes a wall panel 5 and a rear baffle 4, both fixed to the bottom of the packaging machine. The two wall panels 5 are symmetrically arranged on both sides of the bottom of the packaging machine. The rear baffle 4 is connected to the inner wall of the wall panel 5, and its bottom end is sealed to the bottom of the packaging machine. An air blowing mechanism is fixed to the bottom of the rear baffle 4, blowing air into the gap between the bottom of the packaging machine and the corner nail curtain 3. The air blowing mechanism includes a horizontally fixed air distribution pipe 42 connected to the bottom of the rear baffle 4 and air blowing holes 44 opened on the air distribution pipe 42. The air blowing holes 44 are multiple evenly distributed and face the gap between the bottom of the packaging machine and the corner nail curtain 3. The air distribution pipe 42 is connected to a high-pressure air source, usually compressed air, through a connecting pipe 41.

[0031] In this embodiment, the rapid fiber cleaning device for the bottom of the packaging machine is used by connecting an external high-pressure air source to the air blowing mechanism. The high-pressure air source blows away the residual fibers in the gap between the corner nail curtain 3 and the bottom 1, and then hangs the fibers on the corner nail curtain 3. The transmission roller 2 drives the corner nail curtain 3 to rotate, thereby carrying out all the residual fibers. According to calculations, the cleaning of residual fibers between the corner nail curtain 3 and the bottom 1 can be completed quickly within 10 seconds.

[0032] Example 2

[0033] The rapid cleaning device for the inner fiber of the bag opener in this embodiment has the same basic configuration as in Embodiment 1, with the following differences or improvements: Figure 2 , 3 As shown in Figures 4, 5, and 6, the air distribution pipe 42 is a square tube, which is convenient for welding and fixing to the bottom of the rear baffle 4. The connecting pipe 41 is a round tube, which is convenient for connecting and communicating with the air pipe 9. The air blowing hole 44 is a round hole, which ensures uniform air blowing. The round tube, square tube, and baffle are sealed together to avoid loss during the compressed air flow process.

[0034] The side of the wall panel 5 is fixedly connected to a pressure regulating valve 7 and a switch valve 8. The high-pressure air source is connected to the pressure regulating valve 7, the switch valve 8, the quick connector 6 and the connecting pipe 41 in sequence through the air pipe 9, so that the blowing pressure of the compressed air is controllable.

[0035] Pressure regulating valve 7 and valve 8 are installed on wall panel 5; the air inlet of pressure regulating valve 7 is connected to an external air source, and the air outlet is connected to the air inlet of valve 8 through air pipe 9. The air outlet of valve 8 is connected to quick connector 6 through air pipe 9.

[0036] Compressed air enters the round pipe through the pressure regulating valve 7, valve 8, and quick connector 6 in sequence, and finally reaches the square pipe and is ejected from multiple round holes. By adjusting the pressure gauge of the pressure regulating valve 7, the gas pressure of the compressed air can be adjusted, thereby controlling the gas pressure ejected from the round holes.

[0037] The gap between the drain bottom 1 and the corner nail curtain 3 is 2-12mm, which is adjusted by adjusting the upper and lower positions of the drive roller 2. If the gap is too high, the compressed air ejected from the round hole cannot effectively disperse the residual fibers between the corner nail curtain 3 and the drain bottom 1, thus increasing the cleaning time and failing to clean the residual fibers completely. The preferred gap between the drain bottom 1 and the corner nail curtain 3 is ≤12mm.

[0038] Because the gas flow rate from the external air source to the pressure regulating valve 7 is limited, if the diameter of the circular orifice is too large, the pressure drop of the compressed air blown out of the orifice will be too large, making it impossible to disperse the residual fibers between the corner nail curtain 3 and the drain bottom 1. Therefore, the diameter of the air blowing hole 44 is 2-3 mm, and the distance between adjacent circular holes is 65-80 mm. The drain bottom 1 and the rear baffle 4 are sealed together between the left and right wall panels 5 to avoid loss of air pressure.

[0039] Due to the different fiber raw materials, when it is not possible to better disperse the residual fibers between the corner nail curtain 3 and the bottom 1, the pressure gauge of the pressure regulating valve 7 can be increased to increase the gas pressure flowing into the square tube, thereby increasing the gas pressure blown out of the round hole and increasing the force of dispersing the residual fibers.

[0040] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
