[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figures 1 to 4 As shown, in this embodiment, a material shortage detection injection molding equipment includes an injection molding machine 1, an injection die 2, an upper mold 3, a lower mold 4 and a material belt moving mechanism 5. The injection die 2 is fixed directly above the injection molding machine 1, the upper mold 3 is located below the injection die 2, the lower mold 4 is located below the upper mold 3, and the lower mold 4 is fixed on the injection molding machine 1. The material belt moving mechanism 5 is installed on one side of the injection molding machine 1. The material belt moving mechanism 5 controls the material belt to move backward. When the empty material belt enters between the upper mold 3 and the lower mold 4, the injection die 2 controls the material to pass through the upper mold 3 and the lower mold 4 from top to bottom to be molded on the empty material belt.

[0023] The material belt moving mechanism 5 includes a moving base 6, a moving lifting plate 7, a feeding motor 8, a feeding wheel 9 and a feeding guide rail 10. The moving lifting plate 7 moves up and down in the vertical direction above the moving base 6. The two feeding motors 8 are respectively located on both sides of the moving lifting plate 7. The driving end of the feeding motor 8 is fixedly connected to the middle of the feeding wheel 9. A plurality of feeding teeth 11 are formed on the outer periphery of the feeding wheel 9. The feeding guide rail 10 is installed in the middle of the moving lifting plate 7. A feeding moving groove 12 is provided on the feeding guide rail 10. The lower end of the feeding wheel 9 passes through the feeding moving groove 12. A detection fixed seat 13 is fixed to the rear end of the feeding guide rail 10. A sensing optical fiber 14 is installed on the detection fixed seat 13. The sensing direction of the sensing optical fiber 14 is vertically downward.

[0024] After the empty material belt is molded with a product under the injection mold head 2, it enters the material belt moving mechanism 5. The feeding motor 8 controls the feeding wheel 9 to rotate. After the feeding wheel 9 passes through the feeding moving groove 12, the feeding tooth 11 inserts into the belt hole on the material belt and drives the material belt to move. The material belt will move parallel to the feeding guide rail 10. When the material belt moves beyond the feeding guide rail 10, the sensing optical fiber 14 on the detection fixing seat 13 detects the material belt. If a vacancy is found, the machine will automatically stop and wait for processing.

[0025] A material belt adjusting mechanism 15 is arranged on one side of the injection molding machine 1 away from the material belt moving mechanism 5. The material belt adjusting mechanism 15 includes an adjusting base 16, a first adjusting cylinder 17 and an adjusting lifting plate 18. The first adjusting cylinder 17 is fixed on the adjusting base 16. The driving end of the first adjusting cylinder 17 is fixedly connected to the middle part of the adjusting lifting plate 18. A material belt feeding channel 19 is installed on the adjusting lifting plate 18. Moreover, a first guide column 20 is fixed on the periphery of the adjusting base 16. The periphery of the adjusting lifting plate 18 slides on the first guide column 20 along the vertical direction.

[0026] In order to cope with the height of the incoming material belt conveyed in front, when the empty material belt enters above the adjustment base 16, the first adjustment cylinder 17 controls the height of the adjustment lifting plate 18, and the adjustment lifting plate 18 moves up and down along the first guide column 20 so that the position of the material belt corresponds to the lower mold 4.

[0027] An injection molding pipe 21 is installed on the injection molding die head 2, and an injection molding funnel 22 is connected to the upper end of the injection molding pipe 21. Hot melt material is injected into the injection molding funnel 22 and flows from the upper mold 3 into the empty material strip through the injection molding pipe 21 to be molded.

[0028] A second adjusting cylinder 23 is fixed on the movable base 6, and the driving end of the second adjusting cylinder 23 is connected to the middle part of the movable lifting plate 7. Moreover, a second guide column 24 is fixed on the periphery of the movable base 6. The periphery of the movable lifting plate 7 slides on the second guide column 24 along the vertical direction. When docking the material belt with products at the rear, the second adjusting cylinder 23 is also required to control the up and down adjustment position of the movable lifting plate 7, relying on the second guide column 24 for guidance.

[0029] An adjustment slot 25 is horizontally arranged on the detection fixing seat 13, and the upper end of the sensing optical fiber 14 passes through the adjustment slot 25. A hexagonal nut 26 is installed on the sensing optical fiber 14, and the hexagonal nut 26 is pressed on the detection fixing seat 13. According to the position of the product on the material belt, the hexagonal nut 26 can be loosened, so that the position of the sensing optical fiber 14 on the adjustment slot 25 can be changed, thereby accurately corresponding to the detection product.

[0030] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used.
