[0029] Please refer to Figure 1-Figure 3 .

[0030] The embodiment of the present invention provides a feeding device for a moving spring bowl, comprising: a feeding seat 10, a feeding tube 20, a limit switch 30 and a pressure rod 40, wherein the feeding seat 10 is provided with a feeding channel 101 penetrating in a vertical direction, and the side wall of the feeding seat 10 is provided with a feeding hole and a guide hole communicating with the feeding channel 101, wherein the feeding seat 10 can be fixed on the mold base 70, for example, a connecting plate can be provided at the rear end of the feeding seat 10, and the connecting plate can be fixed to the mold base 70 by screws. The base 70 is provided with a blanking seat 10, and the blanking seat 10 is located at the front end of the base 70. The base 70 is fixed to the input end of the processing equipment. The base 70 is used to fix the entire moving spring bowl feeding device and guide the bowl 90 into the processing position. The lower end of the blanking pipe 20 is connected with the feed hole. The blanking pipe 20 extends obliquely upward relative to the blanking channel 101. The blanking pipe 20 is used to allow the bowl 90 to slide into the blanking channel 101. The blanking hole extends in the horizontal direction. The lower end of the blanking pipe 20 can be set to be along the The straight tube extends in the horizontal direction. When the bowl 90 falls into the straight tube, the bowl 90 that subsequently falls into the discharge tube 20 can push the bowl 90 in the straight tube into the discharge channel 101. The limit switch 30 is slidably connected to the guide hole. The limit switch 30 extends into the inner end of the discharge channel 101 to support the bowl 90, wherein the limit switch 30 is preferably a slider. The lower end of the pressure rod 40 is slidably connected to the upper end of the discharge channel 101. The upper end of the pressure rod 40 is provided with a limit portion. A spring 41 is sleeved on the rod 40, and the two ends of the spring 41 are respectively pressed against the limit portion and the upper end of the discharge seat 10. Under the action of the spring 41, the pressure rod 40 is in the initial position. When downward pressure is applied to the pressure rod 40, the pressure rod 40 presses down the bowl 90, and the bowl 90 pushes the limit switch 30 outward. After the bowl 90 passes the limit switch 30, it falls from the lower end of the discharge channel 101. When the pressure rod 40 is released, the pressure rod 40 returns to its original position under the action of the spring 41. The limit switch 30 can prevent the bowl 90 from falling directly from the discharge channel 101. Only when the pressure rod 40 is pressed downward will the bowl 90 be pushed to fall in the vertical direction. Therefore, the timing of the bowl 90 falling can be accurately controlled. Moreover, the pressure rod 40 can push the material to avoid the problem of material jamming, thereby ensuring smooth discharge.

[0031] In some embodiments, as Figure 3As shown, the feed base 10 is provided with a spring clip 50, which can be bolted to the side wall of the feed base 10. The spring clip 50 abuts against the outer end of the limit switch 30. Under the elastic force of the spring clip 50, the inner end of the limit switch 30 is positioned within the feed channel 101. To control the length of the inner end of the limit switch 30 extending into the feed channel 101, a limit protrusion can be provided on the outer end of the limit switch 30. The limit protrusion can be hooked onto the outer end surface of the guide hole. The feed base 10 is provided with two limit switches 30 arranged opposite each other, and two spring clips 50 are also provided on the feed base 10. The outer end of each limit switch 30 abuts against a spring clip 50. When the pressure rod 40 is reset by the action of the spring 41, the limit switch 30 is also reset by the action of the spring clip 50.

[0032] In some embodiments, the inner end of the limit switch 30 is provided with an inclined surface or a curved surface. When the lower end of the cup 90 contacts the inclined surfaces or curved surfaces of the two limit switches 30, the cup 90 pushes the limit switches 30 outward as the pressure rod 40 moves downward. The inclined and curved surfaces can improve the smooth opening of the limit switch 30 and prevent the bottom of the cup 90 from contacting the edge of the limit switch 30, thereby ensuring the surface quality of the cup 90.

[0033] In some embodiments, as Figure 3 As shown, an inclined hole is also provided in the discharge seat 10, which is inclined relative to the discharge channel 101 and is connected to the discharge channel 101. For example, an inclined hole can be provided on both sides of the lower part of the discharge seat 10, and the lower end of the spring 50 passes through the inclined hole and is hooked on the inner wall of the discharge channel 101. The inclined hole can improve the installation stability of the spring 50.

[0034] In some embodiments, the lower end of the pressure rod 40 is provided with a concave arc surface, which matches the outer circumferential surface of the bowl 90. The arc surface can improve the contact effect between the pressure rod 40 and the bowl 90, thereby ensuring the stability of the bowl 90 when it moves downward. In addition, the arc surface is in surface contact with the outer circumferential surface of the bowl 90, which can reduce the probability of the bowl 90 being pressed off-center.

[0035] In some embodiments, as Figure 2As shown, the blanking seat 10 includes a base 11 and a limiter 12. The limiter 12 is connected to the upper part of the base 11. The rear end of the limiter 12 can be provided with a bent plate bent at a right angle. The bent plate can be fixed to the base 11 by bolts. A guide groove running through the limiter 12 in the vertical direction is provided. A blanking channel 101 is provided in the base 11. The lower end of the pressure rod 40 is provided in the guide groove. The side wall of the guide groove is provided with an open groove 121. A notch 122 connected to the blanking channel 101 is provided at the position where the limiter 12 contacts the upper end surface of the base 11. The movement state of the pressure rod 40 can be observed through the opening and gap to avoid the problem of the pressure rod 40 being stuck. In addition, a feed screw 80 can be provided above the pressure rod 40. The feed screw 80 is used to impact the pressure rod 40. A pit corresponding to the feed screw 80 can be provided at the upper end of the pressure rod 40 to improve the accuracy of the feed screw 80 when punching. The cross-sections of the pressing rod 40 and the guide groove are preferably rectangular to ensure that the pressing rod 40 maintains a stable posture when pressed downward.

[0036] In some embodiments, as Figure 1 and Figure 2 As shown, a cover plate 60 is provided on one side of the discharge seat 10, and the cover plate 60 can be connected to the discharge seat 10 by bolts. The discharge pipe 20 is connected to the cover plate 60. For example, a connecting hole corresponding to the feed hole can be provided on the cover plate 60, and the straight pipe of the discharge pipe 20 is connected in the connecting hole. A groove is provided on the outer side of the discharge seat 10, and the cover plate 60 and the groove form a discharge channel 101. This method can reduce the manufacturing difficulty of the discharge channel 101. In addition, when the material is blocked, the cover plate 60 can be removed and the stuck material can be taken out.

[0037] In some embodiments, as Figure 1 As shown, the cover plate 60 is provided with a strip hole 61 extending in the vertical direction. The strip hole 61 is connected to the discharge channel 101. The width of the strip hole 61 is smaller than the diameter of the bowl 90, that is, the bowl 90 will not leak out through the strip hole 61. The falling state of the bowl 90 can be observed through the strip hole 61.

[0038] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0039] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
