AI Technical Summary
The existing method of filling the cotton in the pillow core results in excessive amounts of cotton in the middle of the pillow core, relatively small amount of cotton in the edge part, and uneven cotton filling speed, resulting in uneven distribution of cotton.
A pillow core filling head with uniform cotton filling is designed, using a combination of flat oval cotton filling tube and servo motor roller. The servo motor rotates at a constant speed through the controller to match the cotton filling speed with the pillowcase rollback speed to ensure the uniform distribution of cotton.
The cotton filling is uniformly filled in all parts of the pillow case, ensuring that the corners of the pillow core can also be filled with enough cotton, improving the efficiency and quality of cotton filling.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pillow core production equipment, in particular to a pillow core filling head with uniform filling. Background Art
[0002] The pillow core production process has to go through a cotton filling step. The existing cotton filling method is that a worker holds a pillowcase with an open end and then puts it on a circular cotton filling tube for cotton filling, and the worker pulls the pillowcase out of the circular cotton filling tube while filling the cotton. Since the pillow core is flat as a whole, the cotton filled in the circular cotton filling tube makes the middle of the pillow core have too much cotton and the edge has too little cotton. In addition, the speed at which the worker pulls the pillowcase out of the circular cotton filling tube is uneven, resulting in uneven distribution of cotton in the pillowcase. Utility Model Content
[0003] In order to solve the above technical deficiencies, the utility model provides a pillow core filling head with uniform cotton filling, so that the amount of cotton filled into the pillowcase is more uniform.
[0004] The utility model discloses a cotton-filling head for a pillow core with uniform cotton filling, comprising a cotton-filling tube, the cross-section of the cotton-filling tube is flat and elliptical, the outer side of the cotton-filling tube is polished and smooth, one end of the cotton-filling tube is connected to a cotton-filling fan and a mounting seat is sleeved on the outer side of the cotton-filling tube at this end, support rods are arranged along the length direction of the cotton-filling tube at the upper and lower ends of the mounting seat away from the cotton-filling fan, rollers and servo motors are arranged at the ends of the support rods, the servo motor is transmission-connected to the roller, the servo motor is electrically connected to a controller, the controller is electrically connected to the cotton-filling fan, a gap is left between the roller and the side wall of the cotton-filling tube, and the central axis of the roller is perpendicular to the length direction of the cotton-filling tube.
[0005] When the above device is in use, the open pillowcase is put on the port of the cotton-filling tube, and the upper and lower pillowcases are respectively inserted between the roller and the cotton-filling tube. The servo motor is controlled to rotate by the controller so that the pillowcase is completely covered on the cotton-filling tube. It should be noted here that the circumference of the pillowcase opening should be equal to the circumference of the cotton-filling tube. Then the controller controls the cotton-filling fan to fill the cotton. While filling the cotton, the controller controls the servo motor to rotate at a uniform speed so that the cotton filling speed matches the pillowcase retraction speed. At the same time, the flat oval cotton-filling tube is cooperated to make the cotton filling even in various places in the pillowcase.
[0006] In order to prevent slippage between the roller and the pillowcase when putting on or retracting the pillowcase, a silicone sleeve is provided on the outer side of the roller. The silicone sleeve has a large friction coefficient and is easy to deform. The gap between the silicone sleeve and the side wall of the cotton filling tube can be set smaller, thereby increasing the pressure on the pillowcase when putting on or retracting the pillowcase, making it less likely to slip.
[0007] The utility model provides a pillow core filling head with uniform cotton filling, which has the beneficial effect that the cotton filling tube is set to a flat oval shape, which is more in line with the flat pillow core, so that the corners of the pillow core can also be filled with sufficient cotton. At the same time, during the cotton filling process, the controller controls the servo motor to rotate at a uniform speed, so that the cotton filling speed matches the pillowcase retraction speed, so that the cotton filling in the length direction of the pillowcase is more uniform.

[0009] Figure 2 It is a left view of embodiment 1 of the utility model. DETAILED DESCRIPTION
[0010] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0011] Embodiment 1:
[0012] like Figure 1 , 2 As shown, the utility model discloses a cotton-filling head for a pillow core with uniform cotton filling, comprising a cotton-filling tube 3, the cross-section of the cotton-filling tube 3 is flat and elliptical, the outer side of the cotton-filling tube 3 is polished and smooth, one end of the cotton-filling tube 3 is connected to a cotton-filling fan 1 and a mounting seat 2 is sleeved on the outer side of the cotton-filling tube 3 at this end, a support rod 7 is arranged along the length direction of the cotton-filling tube 3 at the upper and lower ends of the mounting seat 2 away from the cotton-filling fan, a roller 6 and a servo motor 5 are arranged at the end of the support rod 7, the servo motor 5 is transmission-connected to the roller 6, the servo motor 5 is electrically connected to a controller, the controller is electrically connected to the cotton-filling fan 1, a gap is left between the roller 6 and the side wall of the cotton-filling tube 3, and the central axis of the roller 6 is perpendicular to the length direction of the cotton-filling tube 3.
[0013] When the above device is in use, the open pillowcase is put on the port of the cotton-filling tube 3, and the upper and lower pillowcases are respectively inserted between the roller 6 and the cotton-filling tube 3. The servo motor 5 is controlled to rotate by the controller so that the pillowcase is completely covered on the cotton-filling tube 3. It should be noted here that the circumference of the pillowcase opening should be equal to the circumference of the cotton-filling tube 3, and then the controller controls the cotton-filling fan 1 to fill the cotton.
