Description

Technical Field

[0001] This utility model relates to the field of flocking processing technology, and in particular to a spreading device for flocking paper production. Background Technology

[0002] Current flocking technology utilizes the physical property of like charges repelling and unlike charges attracting. The flock fibers are negatively charged, and the substrate to be flocked (such as the base paper) is placed at zero potential or grounded. The flock fibers are attracted by the opposite potential of the substrate and accelerate vertically to its surface. Because the substrate is coated with adhesive, the fibers are vertically fixed to its surface. However, due to the light weight and small size of the flock fibers, it is difficult to control the amount spread during flocking, which easily leads to uneven flocking and affects the quality of the flocked product. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material spreading device for flocked paper production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flocking paper production spreading device includes a conveyor belt for conveying flocked base paper and a spreading box located above the conveyor belt. The spreading box is equipped with an electrostatic generator and a shaking plate. The shaking plate is vibratingly connected to the spreading box. The shaking plate has a discharge hole, which corresponds vertically to the spreading port at the lower end of the spreading box. A spreading roller is rotatably installed on the spreading port.

[0006] Preferably, the material spreading box is provided with a partition that divides its interior into a material spreading chamber and a material discharging chamber. The partition has a partition hole. The material shaking plate is located in the material spreading chamber and corresponds to the partition hole at an interval. The material spreading roller is rotatably arranged in the material discharging chamber.

[0007] Preferably, the feeding chamber is provided with a material distribution plate that is vertically opposite to the partition plate, and the material distribution rollers are distributed on both sides of the material distribution plate.

[0008] Preferably, the material distribution roller and the material dispensing port are laterally distributed at the lower end of the material dispensing box, and the material distribution roller is provided with a brush in the circumferential direction.

[0009] Preferably, the material spreading box is provided with a guide plate that extends at an incline in the middle, and the lower end of the guide plate is provided with a spring that connects to the material shaking plate.

[0010] Preferably, the outer periphery of the material spreading box is rotatably connected to a connecting plate that drives it to swing.

[0011] Preferably, the material shaking plate is recessed downwards, and the outer periphery of the material shaking plate is attached to the inner periphery of the material spreading box.

[0012] Preferably, the material spreading box is provided with a mounting plate for installing an electrostatic generator, which is located above the material shaking plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. Vibrate the material shaking plate inside the spreading box. Control the amount of fluff in the spreading box through the material discharge hole on the material shaking plate to avoid excessive fluff discharge, which would affect the flocking quality. Rotate the material dispersing roller at the spreading port to disperse the fluff and discharge it, so that the fluff can be dispersed and flocked evenly to ensure the flocking quality.

[0015] 2. A partition is installed inside the spreading box below the shaking plate. The partition has holes and swings synchronously with the spreading box. At the same time, two material dispersing rollers are installed at the lower end of the spreading box, distributed on both sides of the material dispersing plate. The pile is fed twice through the two material dispersing rollers and the spreading port, thereby improving the pile flocking effect and ensuring that the pile can be flocked evenly and fully.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-4As shown, a flocking paper production spreading device includes a conveyor belt 5 for conveying flocked base paper 6 and a spreading box 1 disposed above the conveyor belt 5. The upper surface of the flocked base paper 6 is coated with glue. The spreading box 1 contains flocking fibers for flocking the flocked base paper 6. The spreading box 1 is equipped with an electrostatic generator 2 and a shaking plate 3. The spreading box 1 is equipped with a mounting plate 122 for mounting the electrostatic generator 2, and the electrostatic generator 2 is located above the shaking plate 3. The electrostatic generator 2 is used to provide a negative charge to the flocking fibers. This is prior art and will not be described in detail.

[0024] The material shaking plate 3 is recessed downwards, and the outer periphery of the material shaking plate 3 is attached to the inner periphery of the material spreading box 1. The fluff is disposed on the material shaking plate 3, and the material shaking plate 3 is vibratingly connected to the inside of the material spreading box 1.

[0025] Specifically, the material spreading box 1 is provided with a guide plate 121 extending at an incline in the middle. The guide plate 121 corresponds to the upper end of the shaking plate 3. The lower end of the guide plate 121 is provided with a spring 32 that connects to the shaking plate 3. The shaking plate 3 can shake up and down along the inner circumference of the material spreading box 1 through the spring 32.

[0026] The shaking plate 3 has a number of feeding holes 31, which are relatively small in size. The amount of fluff scattered in the spreading box 1 is controlled by the feeding holes 31 on the shaking plate 3, so as to avoid a large amount of fluff falling from the feeding holes 31, that is, to avoid excessive fluff feeding, which would affect the flocking quality.

[0027] The feeding hole 31 corresponds vertically to the feeding port 132 at the lower end of the feeding box 1, and the feeding port 132 corresponds vertically to the conveyor belt 5, so that the flocking material is fed to the flocking base paper 6 through the feeding hole 31 and the feeding port 132.

[0028] Furthermore, a material spreading roller 4 is rotatably mounted on the material spreading port 132 to disperse and distribute the fluff, thereby ensuring that the fluff is dispersed and evenly flocked to guarantee the quality of flocking. In addition, one end of the material spreading roller 4 is connected to a stepper motor that drives its rotation, so that the rotation of the material spreading roller 4 can be precisely controlled by the stepper motor, thereby controlling the amount of fluff scattered at the material spreading port 132 to further improve the flocking effect.

[0029] The material spreading box 1 is provided with a partition 11 that divides its interior into a material filling chamber 12 and a material discharging chamber 13. The partition 11 has a partition hole 111. The material shaking plate 3 is located in the material filling chamber 12 and corresponds vertically to the partition hole 111. That is, the partition 11 is located below the material shaking plate 3, and the material discharging hole 31 and the partition hole 111 are distributed vertically and alternately.

[0030] The outer periphery of the material spreading box 1 is rotatably connected to a connecting plate 14 that drives it to swing. Multiple connecting plates 14 are present, with one end rotatably connected to the material spreading box 1, so that the material spreading box 1 swings back and forth through the cooperation of multiple connecting plates 14 (in this embodiment, the back-and-forth direction refers to the conveying direction of the conveyor belt 5; see reference for details). Figure 1 That is, the material feeding box 1 drives the partition plate 11 to swing synchronously. During the swinging process of the material feeding box 1, the spring 32 drives the shaking plate 3 to shake up and down, thereby controlling the amount of fluff in the fluff cavity 12, so as to avoid excessive fluff feeding and affecting the flocking quality.

[0031] The material dispersing roller 4 and the material dispensing port 132 are laterally distributed at the lower end of the material dispensing box 1. The material dispersing roller 4 is rotatably disposed in the material dispensing chamber 13, and the material dispersing roller 4 is circumferentially provided with a brush 41 so that the rotating material dispersing roller 4 can more easily disperse the fluff to be dispensed.

[0032] The feeding chamber 13 is provided with a distribution plate 131 that is vertically opposite to the partition plate 11. The dispersing rollers 4 are distributed on both sides of the distribution plate 131. There are two dispersing rollers 4 and two sprinkling ports 132. The two dispersing rollers 4 are distributed on both sides of the distribution plate 131 so that the pile is fed twice by the two dispersing rollers 4 and the sprinkling ports 132, thereby improving the pile flocking effect and ensuring that the pile can be flocked evenly and fully.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
