Abstract
Description
Technical Field
[0001] The utility model relates to a flocking device, in particular to a flock supply component of a flocking machine. Background Art
[0002] The flocking machine is a production equipment used for flocking process, which generally includes a control system, a spraying (glue) system, a down supply system, a positioning system, a transmission system, etc. The down supply system is responsible for providing the down required for flocking, which is usually achieved through devices such as a down storage box, a down tube, and a down pump. The quality of the flocking process can be evaluated from many aspects, among which the uniformity of the flocking is also a very important point, and the uniformity of the flocking is largely determined by the performance of the down supply system. The existing down supply method generally uses negative pressure to absorb the down in the down storage box to supply the down nozzle, but because the down stored in the down storage box itself has poor fluidity, it is often drawn away piece by piece when it is sucked by negative pressure, and the volume of the down block drawn away each time cannot be guaranteed to be the same. Therefore, the actual rate of extracting the down cannot be guaranteed to be fixed, which will cause the down spray density of the down nozzle to be the same in real time, so it will cause slight differences in the density of the actual flocking. Therefore, the development of a down supply system that can stably supply down is an urgent problem to be solved in this field. Summary of the invention
[0003] The utility model provides a flock supply component of a flocking machine, which solves the problem in the prior art that the flock supply cannot be guaranteed to be stable, resulting in slight differences in actual flock density.
[0004] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a down supply component of a flocking machine, comprising a down storage barrel, a down flow channel and a down nozzle, characterized in that: a protruding down output tube is provided at the bottom of the down storage barrel, a rotating shaft is coaxially provided in the down output tube, the rotating shaft is arranged to extend to the interior of the down storage barrel, a motor for driving the rotating shaft to rotate is provided on the down storage barrel, and spiral petals distributed in a spiral curve are coaxially provided on the rotating shaft; an air pump and a blowing barrel wrapped around the outside of the down output tube are also included, the air pump, the blowing barrel and the down nozzle are connected in series through the down flow channel; an annular airflow cavity is formed between the blowing barrel and the outer wall of the down output tube, the air inlet of the blowing barrel is located on the side away from the opening of the down output tube, and the exhaust port of the blowing barrel is directly opposite to the opening of the down output tube.
[0005] The utility model sets a rotating shaft with spiral petals in the fluff storage barrel, and drives the rotating shaft to rotate at a uniform speed through a motor, so that the spiral petals can push the fluff from the fluff storage barrel to the fluff output pipe and extrude it relatively stably and evenly; at the same time, the airflow output by the air pump passes through the fluff flow channel and continuously flows through the blowing barrel. The fluff extruded from the outlet of the fluff output pipe will be carried away by the airflow blown out of the annular airflow cavity and flow along the fluff output pipe to the fluff nozzle. Since the utility model supplies fluff in the above manner, the fluff flow rate output from the fluff output pipe is relatively stable, and the fluff is then transported to the fluff nozzle and output by the airflow. Compared with existing equipment, it has the advantages of stable fluff output and good uniformity.
[0006] Furthermore, a vortex body is provided on the fluff flow channel at the rear end of the blowing barrel, a pneumatic turbine is provided in the vortex body, an inner cavity of the vortex body forms an annular vortex cavity surrounding the pneumatic turbine, and the air inlet direction on the vortex body is tangent to the annular vortex cavity; after the airflow enters the vortex body, it circles around the annular vortex cavity for one circle and then flows out from the exhaust port. The airflow flowing out of the blowing barrel will entrain the fluff, which is unevenly distributed in the airflow. When the airflow enters the vortex body, the airflow can only flow in an arc along the annular vortex cavity, while driving the pneumatic turbine to rotate. The pneumatic turbine will produce a stirring effect on the airflow, which can break up the fluff in the airflow, so that the fluff is more evenly dispersed in the airflow, which is conducive to improving the uniform ejection of the fluff of the utility model.
[0007] Furthermore, the inner diameter of the fluff flow channel connecting the vortex body and the blowing barrel is smaller than the inner diameter of the annular vortex cavity and the blowing barrel. Thus, when the airflow in the blowing barrel enters the fluff flow channel at the rear end, the airflow channel becomes narrower, so the airflow will be squeezed and the flow rate will increase sharply. Then, after the airflow accelerated by squeezing enters the vortex body, the airflow channel becomes larger and the air pressure suddenly decreases, which will promote the dispersion of the fluff in the airflow.
[0008] Furthermore, a flexible compression sheet covering the fluff is provided in the fluff storage barrel, and the contour of the flexible compression sheet is adapted to the inner cavity contour of the fluff storage barrel. The flexible compression sheet applies a certain pressure to the fluff by its own weight, prompting the fluff to move toward the rotating shaft, ensuring that the spiral petal can reliably output the fluff.
[0009] Furthermore, a metal spring sheet arranged in a downward tilt is provided on the inner wall of the fluff storage bucket, and a metal contact is also provided, and the metal contact and the metal spring sheet are electrically connected with a detection circuit; during the descent of the flexible pressure sheet, the metal spring sheet will be pressed down until it contacts the metal contact, so that the detection circuit is connected, which means that the fluff stock in the fluff storage bucket is insufficient at this time, and the worker can be notified to add fluff through sound, light and electricity and other means.
[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model supplies down in the above-mentioned manner, and the flow rate of the down output from the down output tube is relatively stable. The down is then transported to the down nozzle and output through the airflow. Compared with the existing equipment, it has the advantages of stable down output and good uniformity; 2. After the airflow enters the vortex body, the airflow can only flow in an arc shape along the annular vortex cavity, while driving the wind turbine to rotate. The wind turbine will produce a stirring effect on the airflow, which can break up the down in the airflow, making the down more evenly dispersed in the airflow, which is beneficial to improving the uniform spraying of the down of the utility model.

[0015] Example 1: See Figure 1 A down supply component of a flocking machine includes a down storage barrel 10, a down flow channel 20 and a down nozzle 30. A protruding down output tube 11 is provided at the bottom of the down storage barrel, and a rotating shaft 40 is coaxially provided in the down output tube. The rotating shaft is arranged to extend to the inside of the down storage barrel and penetrate the down storage barrel. A motor 50 for driving the rotating shaft to rotate is provided on the outside of the down storage barrel, and spiral petals 41 distributed in a spiral curve are coaxially provided on the rotating shaft; an air pump 60 and a blowing barrel 70 wrapped around the outside of the down output tube are also included. The air pump, the blowing barrel and the down nozzle are connected in series through the down flow channel; an annular airflow cavity 71 is formed between the blowing barrel and the outer wall of the down output tube, the air inlet of the blowing barrel is located on the side away from the opening of the down output tube, and the exhaust port of the blowing barrel is directly opposite to the opening of the down output tube.
[0016] See Figure 1A vortex body 80 is also provided on the fluff flow channel at the rear end of the blowing barrel, and a wind turbine 81 is provided in the vortex body. The inner cavity of the vortex body forms an annular vortex cavity 82 surrounding the wind turbine, and the air inlet direction on the vortex body is tangent to the annular vortex cavity; after the airflow enters the vortex body, it circles around the annular vortex cavity for one circle and then flows out from the exhaust port.
[0017] The present embodiment arranges a rotating shaft with spiral petals in the fluff storage barrel, and drives the rotating shaft to rotate at a uniform speed through a motor, so that the spiral petals can push the fluff from the fluff storage barrel to the fluff output pipe and extrude it in a relatively stable and uniform manner; at the same time, the airflow output by the air pump passes through the fluff flow channel and continuously flows through the blowing barrel. The fluff squeezed out from the outlet of the fluff output pipe will be carried away by the airflow blown out of the annular airflow cavity, and flow along the fluff output pipe to the vortex body. When the airflow enters the vortex body, the airflow can only flow in an arc shape along the annular vortex cavity, and at the same time drive the pneumatic turbine to rotate. The pneumatic turbine will produce a stirring effect on the airflow, which can break up the fluff in the airflow, so that the fluff is dispersed more evenly in the airflow, which is beneficial for the fluff nozzle of the present embodiment to spray fluff evenly and stably.
[0018] See Figure 1 The inner diameter of the fluff flow channel connecting the vortex body and the blowing barrel is smaller than the inner diameter of the annular vortex cavity and the blowing barrel. In this way, when the airflow in the blowing barrel enters the fluff flow channel at the rear end, the airflow channel becomes narrower, so the airflow will be squeezed and the flow rate will increase sharply. Then, after the squeezed and accelerated airflow enters the vortex body, the airflow channel becomes larger and the air pressure suddenly decreases, which will promote the dispersion of the fluff in the airflow.
[0019] See Figure 1 A flexible pressing sheet 90 covering the fluff is provided in the fluff storage barrel, and the contour of the flexible pressing sheet is adapted to the inner cavity contour of the fluff storage barrel. The flexible pressing sheet applies a certain pressure to the fluff by its own weight, prompting the fluff to move toward the rotating shaft, ensuring that the spiral flap can reliably output the fluff.
[0020] See Figure 2 A metal spring 12 tilted downward is provided on the inner wall of the fluff storage bucket, and a metal contact 13 is also provided. The metal contact and the metal spring are electrically connected with a detection circuit, and the metal spring and the metal contact are insulated from the fluff storage bucket. During the descent of the flexible pressing piece, the metal spring will be pressed down until it contacts the metal contact, so that the detection circuit is connected, which means that the fluff stock in the fluff storage bucket is insufficient at this time, and the worker can be notified to add fluff through sound, light and electricity and other means.
[0021] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
