Description

Technical Field

[0001] The utility model relates to the technical field of pillow production, in particular to a cotton filling device for pillow production. Background Art

[0002] A cotton filling machine, also known as a stuffing machine, is a device used to inject fillers such as PP cotton into plush toys, sofa cushions, pillows or pillow core shells. It is usually used in industries such as plush toys, home textiles, furniture and clothing. The outer shell of a cotton filling machine is generally made of cold plate and is sprayed with plastic or painted. It is equipped with a stirring device and a small gas storage tank inside, and is equipped with a foot switch device. The filler is first sucked into the cotton filling machine through a cotton suction machine or other equipment. After being fully stirred and mixed in the machine, the foot switch is stepped on to use the pressure of the gas to inject the filler into the shell of the product to be filled, completing the filling process;

[0003] After searching, a Chinese patent with the announcement number of CN215924384U discloses a cotton filling device for pillow production. The patent records that a gathering mechanism is provided at one end of the inner wall of the cotton filling cylinder to reduce the spray outlet, so that the sprayed cotton is more compacted, saving the time of compacting the pillow core in the later stage, saving resources and costs. At the same time, a fixing mechanism is also provided on the outer wall of the cotton filling cylinder, and the pillow core sleeve that is not filled with cotton is fixed to the outer wall of the cotton filling cylinder through the fixing mechanism to prevent the pillow core sleeve from being blown away by the cotton sprayed from the cotton filling cylinder, thereby ensuring the smooth progress of the work.

[0004] In this solution, when the pillowcase is filled with cotton, the pillowcase is fixed by a simple semi-fixed ring and a magnetic block. When the cotton inside the pillowcase becomes more and more, the internal air circulation is slow. At this time, when the cotton is continued to be filled, the pillowcase will be squeezed out under the action of pressure, causing the pillowcase to detach from the cotton filling tube, thereby causing the cotton to spray outside, prompting the staff to clean it up, resulting in reduced work efficiency. In order to solve this technical problem, the utility model proposes a cotton filling device for pillow production. Summary of the invention

[0026] Insert one side opening of the pillowcase on the cotton filling cylinder 3 and level it. After starting the motor 5 on the top plate 4, the motor 5 drives the bidirectional threaded rod 6 to rotate. This causes the connecting block 7 to move in the opposite direction on the bidirectional threaded rod 6, thereby pushing the pressing plate 8 and the pressing ring 10 to approach the cotton filling cylinder 3. At the same time, the positioning column 9 is used to limit the direction of movement of the pressing ring 10 to ensure consistency. Through their cooperation, the pillowcase can be quickly compressed, and compressing the pillowcase can prevent it from detaching during the cotton filling process. Subsequently, the cotton filling machine body 1 is started to start filling the pillowcase with cotton to improve work efficiency.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the top of the top plate 4 is fixedly connected to the fixing plate 2, and the top of the fixing plate 2 is fixedly connected to the hydraulic rod 12, the output end of the hydraulic rod 12 is fixedly connected to the connecting frame 13, and the connecting frame 13 is L-shaped, the connecting frame 13 is located below the top plate 4, the outer wall of the connecting frame 13 is fixedly connected to the electric push rod 2 14, the output end of the electric push rod 2 14 is fixedly connected to the support plate 17, and the support plate 17 is slidably connected to one side of the connecting frame 13, and the connecting frame 13 A slide groove 15 is opened inside, and a slider 16 is fixedly connected to the outer wall of the support plate 17, and the slider 16 is slidably connected in the slide groove 15. The slider 16 is convex in shape, and the slider 16 corresponds to the slide groove 15. A pair of limit rods 19 are fixedly connected to the top of the connecting frame 13, and the limit rods 19 pass through the top plate 4 and are slidably connected in the top plate 4. A sewing head 18 is provided on the other side of the support plate 17. A workbench 11 is provided at the bottom of the cotton filling machine body 1, and the workbench 11 is located directly below the connecting frame 13 and the support plate 17.

[0028] By starting the hydraulic rod 12 on the fixed plate 2, the hydraulic rod 12 drives the connecting frame 13 to move downward, and the consistency of the moving direction is ensured by the action of the limit rod 19. The downward movement of the connecting frame 13 causes its bottom to directly press the opening of the pillowcase. Next, start the sewing head 18 to start sewing the opening of the pillowcase. At the same time, use the electric push rod 14 to push the support plate 17 to move left and right, driving the sewing head 18 to move forward and backward. The slider 16 is limited in the slide groove 15 to keep the movement of the sewing head 18 stable. While the pillowcase is being sewn, the workbench 11 supports the pillowcase. This combination allows the opening of the pillowcase to be sewn quickly and accurately, thereby significantly improving work efficiency.

[0029] Working principle: when the staff needs to fill the pillowcase with cotton, first insert the opening on one side of the pillowcase into the cotton filling tube 3, then flatten the pillowcase, and start the motor 5 on the top plate 4. Under the action of the motor 5, the bidirectional threaded rod 6 is driven to rotate, and the rotation of the bidirectional threaded rod 6 will drive the connecting blocks 7 on the upper and lower sides to move in opposite directions. At this time, the connecting blocks 7 will drive the pressure plates 8 on the upper and lower sides to move in opposite directions when moving. The movement of the pressure plate 8 will drive the pressure ring 10 to move and gradually move closer to the cotton filling tube 3. At the same time, the pressure ring 10 is limited by the positioning column 9 when moving, so as to ensure that the pressure ring 10 maintains the same direction when moving. The pillowcase will be pressed tightly by the movement of the pressure ring 10 to prevent the pillowcase from detaching when filling cotton. The pillowcase is filled with cotton by starting the cotton filling machine body 1, thereby improving To improve work efficiency, after the filling is completed, the hydraulic rod 12 on the fixed plate 2 is started, and the connecting frame 13 is driven to move downward under the action of the hydraulic rod 12. The connecting frame 13 is limited by the limiting rod 19 to ensure that the direction of the connecting frame 13 remains consistent when it moves downward, and the bottom of the connecting frame 13 will directly press the opening of the pillow case. At this time, the sewing head 18 is started to sew the opening of the pillow case, and the electric push rod 14 is used in conjunction with the support plate 17 to move left and right under the action of the electric push rod 14, thereby driving the sewing head 18 to move forward and backward, and at the same time, it will be limited in the slide groove 15 by the slider 16. The opening of the pillow case can be quickly sutured by the back and forth movement of the sewing head 18. At the same time, the pillow case is supported by the workbench 11 during sewing. Through their cooperation, the work efficiency is greatly improved.
