Description of the invention (1) The invention is related to a roller skate, more specifically, it refers to a roller skate that can produce good suction. The cracking method (2). Pressing, skating is an activity that combines both lotus movement and rest, especially the skating lotus movement on the land with general wheeled skates is more popular with the Chinese people. The pulley of this type of skates directly contacts the ground and is structurally It must have moderate strength and high degree, in order to respond to various road conditions on the skates, so the skates used for skating have always been the focus of the industry's creative creation. The pulleys of general skates are usually made by molding. Please refer to the first figure. The pulleys 10 of traditional skates are first scheduled.

Surface, forming one of the outer ring bodies 13 in a ring shape, and a complete pulley 10 can be manufactured. It is true that the above-mentioned process can indeed make a complete roller skate, but the manufactured pulley will actually avoid the bad situation when it is actually used, that is, the pulley 10 of this structure rotates when the roller skate is sliding The outer ring body 13 of its PU plastic material is in direct contact with the ground. The vibration caused by the unevenness of the ground is directly transmitted to the outer ring body 13. Such a solid PU outer ring body 13 cannot effectively absorb vibration, so there are still The great vibration force is transmitted to the hub 11, and the body of the skates bears the vibration force, which keeps the user's foot in a state of being impacted all the time, affecting the nerves of the foot and causing lotus damage. In view of this, the inventor of this case has thought through and thought, and accumulated many years of experience in professional PU plastic materials research and development, and finally the invention was born. That is, the main purpose of the present invention is to provide a system for making roller skates.

Description of the invention (2) Manufacturing method, by making a pu foamed inner ring body, sleeved on the outer circumferential surface of the hub, and then PU plastic injection molding forms an outer ring body, which is coated on the hub and the inner ring body to form a pulley with a good brook avoidance effect. The reason is that according to a method for manufacturing a roller skate pulley provided by the present invention (2), It includes the following steps: 1. Joining and forming inner mold tube: pseudo-take a predetermined length of flexible hot-melt hose, butt the two ends of the two ends to each other, and apply hot-pressing to form one of the closed ring tubes Inner mold tube; 2. PU foam infusion: pseudo A through hole is formed on the outer wall of the inner mold tube, and PU plastic mass is poured through the through hole and foamed. After the inner mold tube is filled with PU foam, it will automatically form one of the full-fledged ring tubes. Inner ring body; 3. Combined overmolding: the inner ring body is sheathed on a peripheral surface of the hub, placed in a mold and heated, and an outer ring body is injected with PU plastic to cover the inner ring body and the wheel valley periphery The inner mold tube is melted by heat to form a film, which is glued between the PU foam and the outer ring body to form a complete skate roller. Related technologies, means and effects of the present invention Here, a preferred embodiment will be described in detail in conjunction with the drawings, and the above-mentioned purposes, structure and pending features of the present invention will be doubled, so that we can get an in-depth and specific understanding from the drawings.

The A7 B7 is printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. One of the inner mold tubes 24 is formed as a closed ring tube; two. Infusion of PU foam: please match the fourth and fifth figures at the same time, a through hole 241 is formed in the outer wall of the inner mold tube 24 to communicate with the inner mold tube 24 Inside, the PU plastic mass is poured from the through hole 241 and foamed. After the inner mold tube 24 is expanded with a PU foam 25, the inner ring body that is full of a circular tube is automatically propped 22; 3. Combined overmolding: please also refer to the sixth and t diagrams, the inner ring body 22 is bundled on the circumference of the hub 21, and placed in a predetermined mold for heating (about 80 ~ 901C), and an outer ring body 23 is injected with PU plastic, covering the inner ring body 22 and the hub On the 21st surface, at this time, the inner mold tube 24 of the outer layer of the inner body 22 is in direct contact with the heated outer ring body 23 after injection molding, resulting in the melted rubber dust between the PU foam 25 and the outer ring body 23, forming One layer of film 26, which has the role of a scavenger, can just serve as an intermediate medium between the PU foam 25 and the outer ring body 23, and tightly adhere the two to form a complete skate roller 20. It can be seen from the above process that the case has the following advantages: (1). The product has good shock absorption effect. In the present invention, an inner ring body 22 is sheathed between the hub 21 and the outer ring body 23, and the inner ring body 22 is made of PU The bubble body 25 has good absorption and cushioning ability. When the outer ring body 23 is in contact with the ground to generate a vibration force, the vibration force is transmitted to the inner ring body 22 and absorbs most of the vibration, which is quite excellent. Suspension capability. (2). No mold is needed to make the inner ring body 22. In the present invention, when forming the inner ring body 22, a section of flexible hot-melt hose is bent and joined to form the inner mold tube 24, and the inner mold tube 24 is directly filled with PU Foam body 25 forms inner ring body 22, page 06 This paper size is applicable to China National Standard (CNS) A4 specification (210X297mm) IIII i III line (please read the precautions on the back before filling this page) A7 _B7 5. Description of invention (6) No need to develop and manufacture expensive wedge sets. (3). The bonding is good. During the manufacturing process of the present invention, the inner chess tube 24 of the outer layer of the inner ring body 22 will automatically melt due to contact with the heat source, forming a layer of film between the PU foam 25 and the outer ring body 23 26. Since the film 26 is similar to the PU foam 25 and the outer ring body 23 of PU plastic material, it has good affinity and connection, and can effectively integrate the PU foam body 25 and the outer ring body together. twenty three. In summary, the present invention has its excellent progress and practicality in similar products. At the same time, it has not been found that the same structure exists first in the technical information and literature on such structures at home and abroad. Therefore, The present invention already possesses the essentials of the invention patent, and the application is filed according to law.
