[0024] The positioning fixture mechanism 5 includes, from top to bottom, a positioning fixture 501 and a compression spring 502 mounted on the positioning fixture 501, a fixture guide sleeve 503, a silicone pad 504, a composite copper sleeve 505, a fixture mounting seat 506 and a fixture limit block 507. The plurality of components are combined to form the positioning fixture mechanism 5. The positioning fixture 501 is used to sleeve the bottom of the rubber cup sleeve. The rear portion of the positioning fixture 501 is provided with an annular assembly groove for assembling the front end of the compression spring 502. The front portion of the fixture mounting seat 506 is provided with a An installation groove is provided. After the jig guide sleeve 503, the silicone pad 504 and the composite copper sleeve 505 are installed, the installation groove can accommodate the jig guide sleeve 503, the silicone pad 504 and the composite copper sleeve. A plurality of connecting screws are also provided around the jig mounting seat 506 for fixed connection with the front end of the jig mounting arm 205. The bottom of the jig mounting seat 506 is limited by a jig limit block 507, and the jig limit block 507 is fixedly connected to the rear end of the positioning jig 501 by a plurality of screws.

[0025] The rear portion of the positioning fixture 501 is a cylindrical structure, and a groove is provided on the side of the cylindrical structure for assembling the fixture guide sleeve 503 . A plurality of screw holes are provided at the rear end of the cylindrical structure for connecting the fixture limit block 507 .

[0026] The front of the jig guide sleeve 503 is provided with an annular groove for assembling the rear end of the compression spring 502, and the rear of the jig guide sleeve 503 is provided with an inwardly protruding assembly portion for matching the groove on the side of the cylindrical structure.

[0027] The horizontal slide mechanism 2 includes a mounting plate 201 and a horizontal servo motor 206, a horizontal linear guide 202, a horizontal slot photoelectric, a horizontal ball screw 203 and a fixture mounting arm 205 arranged in the mounting plate 201.

A first slider 204 is slidably connected to the horizontal ball screw 203 and the first slider 204 is slidably connected to the linear guide. The fixture mounting arm 205 is fixedly connected to the slider. The first slider 204 is controlled to slide back and forth by the forward and reverse rotation of the horizontal servo motor 206, thereby causing the positioning fixture mechanism 5 to move back and forth.

[0028] The horizontal linear guide 202 is fixedly installed on the mounting plate 201, and the mounting plate 201 has an E-shaped structure. The horizontal servo motor 206 is installed at one end of the mounting plate 201. Both ends of the horizontal ball screw 203 are installed in the mounting plate 201 and one end of the horizontal ball screw 203 is connected to the output end of the horizontal servo motor 206.

[0033] Working principle: After the rubber cup bottom sleeve A is placed on the positioning fixture 501, the operator controls the start switch on the switch box to operate the vertical slide mechanism 3, driving the horizontal slide mechanism 2 to move straight up. After the horizontal slide mechanism 2 moves to a preset height, the vertical slide mechanism 3 stops running, and the horizontal slide mechanism 2 starts running, so that the fixture mounting arm 205 moves forward horizontally, and the rubber cup bottom sleeve A is sent into the head of the blow molding machine. After the rubber cup bottom sleeve A is sent into the head of the blow molding machine and stops for a certain period of time, the vertical slide mechanism 3 descends, and the rubber cup bottom sleeve A is separated from the positioning fixture 501. The mechanical parts inside the blow molding machine will grab the rubber cup bottom sleeve A, and the loading is completed. When the parts return to their initial positions, the above actions are repeated to repeat the loading.

[0034] The feeding mechanism of the present scheme is provided with a jig positioning mechanism, the front end of which can position the rubber cup bottom sleeve A, and the rear part is provided with a compression spring 502 for buffering to ensure stable feeding. A jig guide sleeve 503 and a composite copper sleeve 505 are provided inside to ensure the accuracy of feeding. The rubber cup bottom sleeve A is located behind the jig positioning mechanism, and the jig positioning mechanism can realize horizontal and vertical movement through the horizontal slide mechanism 2 and the vertical slide mechanism 3 to transfer the rubber cup bottom sleeve A to the blow molding machine.

[0035] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings.
