Embodiment Construction

[0039] The drawings of the preferred embodiments of the present invention are further described below in order to enable those skilled in the art to implement according to the statements in this specification.

[0040] First, see Figure 1 to Figure 11 As shown, the present invention is an integrated thermal welding process of a seat cushion, comprising: the following steps:

[0041] (a) Material preparation step S01: prepare a seat cushion body 10 and a bottom shell layer 20, the seat cushion body 10 is fixed on a rubber shell layer 11 with an elastic layer 12, and the elastic layer 12 is covered with a surface layer 13, the The periphery of the surface layer 13 is folded back to the lower side of the rubber shell layer 11 and fixed with glue or / and nails. The bottom of the rubber shell layer 11 of the seat cushion body 10 is provided with a plurality of first hot-melt lines 111 protruding from the bottom. The top of the shell layer 20 is protrudingly provided with a plurali...

Abstract

The invention provides an integrated hot melting process of a seat cushion. The integrated hot melting process comprises the following steps: a material preparation step: preparing a seat cushion body and a bottom shell layer; a mold placing step: placing the seat cushion body into a lower mold in an inverted manner, and placing the bottom shell layer into an upper mold in an inverted manner for adsorption; a hot plate inserting step: inserting a hot plate between the upper die and the lower die; a melting step: enabling the upper mold and the lower mold to be close to the hot plate, enabling the plurality of first hot melting line end surfaces and the plurality of second hot melting line end surfaces to be in contact with the hot plate, and melting into a molten state; taking out the hot plate: withdrawing the upper die and the lower die, and withdrawing the hot plate outwards; a hot melting step: the upper mold and the lower mold are closed, so that the rubber shell layer and the bottom shell layer are welded and combined into a whole through the plurality of first hot melting lines and the plurality of second hot melting lines; taking out a finished product: withdrawing the upper mold and the lower mold, and taking out the finished product; therefore, the attractiveness and the firmness of the seat cushion can be improved.

Description

technical field [0001] The invention relates to a seat cushion manufacturing process, in particular to an integrated heat-welding process of the seat cushion. Background technique [0002] General pedal-driven appliances, such as bicycles, exercise bikes, etc., are mostly provided with a cushion for supporting the user's body. The seat cushion usually includes a bottom shell layer, a surface layer and an elastic layer, and the elastic layer is arranged on the bottom shell. Between the layer and the surface layer, the bottom shell layer is used to support the weight of the user and the seat cushion is fixed on the pedal driving device with a fixing device. The surface layer (such as synthetic plastic skin) is used to connect with the user The elastic layer is used to provide moderate elasticity and cushioning shock-absorbing effect. [0003] In the prior art seat cushion manufacturing process, a bottom shell layer, a surface layer and an elastic layer are prepared first, the...
