Description

Technical Field

[0001] The invention relates to the technical field of pillow core processing, in particular to a full-automatic polyurethane pillow core pouring production line. Background Art

[0002] A pillow is a sleeping tool. It is generally believed that a pillow is a filler used by people for sleeping comfort. From the perspective of modern medical research, the human spine is a straight line when viewed from the front, but has three physiological curves when viewed from the side. In order to protect the normal physiological curvature of the neck and maintain normal physiological activities during sleep, people must use pillows when sleeping. A pillow is generally composed of two parts: a pillow core and a pillowcase. Pillows are divided into many types according to the different pillow cores. Now many people advocate health pillows, and fill the pillow core with various sleeping and meditation herbs to help people sleep better. However, if this type of filler is used for too long, it will breed bacteria and mites, affecting physical health.

[0003] In the prior art, the production process of pillow cores includes multiple production stages, and these production stages are separated from each other and produced independently; however, the disadvantages of this are that the connection between the various production parts is not close, and the transfer of semi-finished products during the production process requires too much manpower, which increases the production cost and time, and also reduces the production efficiency.

[0004] The existing patent (publication number: CN204322401U) discloses a latex pillow production line, which can overcome the shortcomings of the existing technology that the various production stages are not closely connected and the transfer of semi-finished products during the production process requires too much manpower by connecting the various parts of the latex pillow production equipment and processes in series, thereby improving production efficiency and reducing production costs. The new implementation is simple and easy to operate, can realize automated production, save manpower and material resources, and greatly reduce production costs.

[0005] However, the latex pillow production line designed above still has some shortcomings in actual application: for example, the production line designed above is not equipped with a drying device. Since the shape of the pillow core cannot be fixed immediately after injection molding, and the rubber coating of the outer layer of the pillow core is also in a viscous state, the production line designed above needs to be naturally dried for a certain period of time after injection molding before it can be fixed and unloaded. Natural drying of the pillow core will greatly reduce the production efficiency of the pillow core, thereby affecting the output. In addition, the production line designed above is not equipped with an impurity removal device. Since impurities will fall on the processing machine during the injection molding process, if it is not cleaned regularly, it is likely to affect the subsequent production quality, and manual cleaning is time-consuming and labor-intensive. For this reason, we designed a fully automatic polyurethane pillow core casting line to solve the above problems. Summary of the invention
