Detailed Embodiments

[0022] The preferred embodiments of the present utility model will be described in more detail below with reference to the drawings. Although the preferred embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to be able to fully convey the scope of the present utility model to those skilled in the art. Embodiment 1

[0023] As Figure 1As shown in the figure, this embodiment provides an injection molded part dispenser, which includes a dispenser 1. A push rod 11 is arranged inside the dispenser 1, and a push plate 12 is connected to the bottom of the push rod 11. A filter belt 13 is arranged inside the dispenser 1. The filter belt 13 is arranged near the bottom of the dispenser 1. The filter belt 13 is arc-shaped, and a glue outlet 14 is formed below the filter belt 13. A space for accommodating glue is formed between the filter belt 13 and the push plate 12. A limiting component 15 is arranged inside the dispenser 1, and the limiting component 15 is used to limit the movement of the push plate 12.

[0024] The dispenser 1 includes a feeding part 16. The bottom of the feeding part 16 is connected to a gradual change part 17, and the bottom end of the gradual change part 17 is connected to a discharging part 18. The diameter of the feeding part 16 gradually decreases from top to bottom.

[0025] The bottom of the push rod 11 is connected to a suction cup 19, and the bottom of the suction cup 19 adsorbs on the push plate 12.

[0026] The size of the push plate 12 is the same as the size of the inner wall of the dispenser 1, and the suction cup 19 adsorbs on the middle of the push plate 12. Starting from the connection part of the gradual change part 17 and the feeding part 16 to the connection part of the gradual change part 17 and the discharging part 18, the diameter of the gradual change part 17 gradually decreases. The arrangement of the gradual change part 17 can increase the pressure for squeezing out the glue downward.

[0027] The limiting component 15 includes a first spring 151 and a second spring 152. The first spring 151 and the second spring 152 are arranged oppositely on both sides of the gradual change part 17.

[0028] The fixed ends of the first spring 151 and the second spring 152 are both located on the gradual change part 17, and the movable ends of the first spring 151 and the second spring 152 are both arranged close to the push plate 12.

[0029] During the process that the push rod 11 drives the push plate 12 to move downward, the push plate 12 squeezes out the glue in the dispenser 1 from the glue outlet 14. The push plate 12 first contacts the first spring 151 and the second spring 152, and the first spring 151 and the second spring 152 start to be compressed. As the push plate 12 moves downward, the compression amounts of the first spring 151 and the second spring 152 gradually increase. Until the push plate 12 is in a force balance state, the push plate 12 no longer moves downward. The push rod 11 moves upward, driving the push plate 12 to move upward, and the springs gradually elongate until the push plate 12 disengages from the springs. The push rod 11 continues to drive the push plate 12 to move upward until the push rod 11 can no longer move upward. At this time, the push plate 12 returns to the initial position.

[0030] A pull rod 3 is penetrated through the side wall of the dispenser 1. A groove is provided in the pull rod 3. A part of the filter belt 13 is located in the groove of the pull rod 3. The pull rod 3 is used to pull out the filter belt 13.

[0031] Pull the pull rod 3 outwards to shorten the length of the filter belt 13, reduce the arc of the filter belt 13 inside the dispenser 1, reduce the amount of glue on the filter belt 13, and thus reduce the dripping speed of the glue droplets. Push the pull rod 3 inwards to increase the length of the filter belt 13, increase the arc of the filter belt 13 inside the dispenser 1, increase the amount of glue on the filter belt 13, and thus increase the dripping speed of the glue droplets.

[0032] An injection molded part dispenser provided in this embodiment includes a dispenser 1. A push rod 11 is provided inside the dispenser 1. A push plate 12 is connected to the bottom of the push rod 11. A filter belt 13 is provided inside the dispenser 1. The filter belt 13 is arranged close to the bottom of the dispenser 1. The filter belt 13 is arc-shaped. A glue outlet 14 is provided below the filter belt 13. A space for containing glue is formed between the filter belt 13 and the push plate 12. A limiting component 15 is provided inside the dispenser 1. The limiting component 15 is used to limit the movement of the push plate 12. The push rod 11 moves downward from top to bottom, driving the push plate 12 to move downward from top to bottom, pressing the glue between the push plate 12 and the filter belt 13 downward. After passing through the filter belt 13, the glue drips from the bottom of the dispenser 1 onto the device 8 to be processed. The filter belt 13 has a screening effect on the glue and can limit the dripping speed of the glue droplets. The limiting component 15 inside the dispenser 1 can limit the distance that the push plate 12 moves downward, thereby controlling the dripping speed of the glue droplets and preventing too much glue from clogging the glue outlet 14 at the bottom of the dispenser 1.

[0038] The first knob 2 is threadedly connected with the limiting plate 153. By rotating the first knob 2 clockwise or counterclockwise, the limiting plate 153 can be pulled out from the inside of the dispenser 1 or pushed into the dispenser 1.

[0039] When the limiting plate 153 is all located outside the dispenser 1, the limiting plate 153 does not play a limiting role on the push plate 12; when a part of the limiting plate 153 is located inside the dispenser 1, the height of the push plate 12 can be limited above the height of the limiting plate 153, and the size of the channel for the glue to fall in the dispenser 1 can also be reduced, thereby reducing the dripping speed of the glue from the glue outlet 14.

[0040] A pull rod 3 is penetratively arranged on the side wall of the dispenser 1. A groove is arranged inside the pull rod 3. A part of the filter belt 13 is located in the groove of the pull rod 3, and the pull rod 3 is used to pull out the filter belt 13.

[0041] Pull the pull rod 3 outwards to shorten the length of the filter belt 13, reduce the radian of the filter belt 13 inside the dispenser 1, and reduce the amount of glue on the filter belt 13, thereby reducing the dripping speed of the glue. Push the pull rod 3 inwards to increase the length of the filter belt 13, increase the radian of the filter belt 13 inside the dispenser 1, and increase the amount of glue on the filter belt 13, thereby increasing the dripping speed of the glue.
