[0031] Embodiment 1

[0032] Please refer to Figures 1-7 , an embodiment provided by the present invention: a product weighing and packaging device, including a support base 1 for support, aluminum profile columns 5 are arranged at the four corners of the upper end surface of the support base 1, and a support clamping plate 4 is fixedly arranged on the upper end surfaces of the four groups of aluminum profile columns 5.

[0033] The feeding device 3 is fixedly arranged at the center of the inner end surface of the support clamping plate 4;

[0034] The support base 1, there are two groups of support bases 1 in total, and both groups of support bases 1 are arranged on the upper end surface of the weighing module 7;

[0035] The packaging device 2 is slidably clamped on the upper end surface of the support base 1 through the weighing module 7, and a servo motor 6 is arranged at the rear end surface of the packaging device 2.

[0036] The packaging device 2 includes a support device 22. At the position near the bottom of the inner end surface of the support device 22, two positioning lead screws 210 are rotatably clamped, and a transmission shaft 213 is arranged at the position near the side of the inner end surface of the support device 22. At the ends of the transmission shaft 213 and the positioning lead screws 210, first synchronous belt pulleys 21 are arranged. Between the two first synchronous belt pulleys 21 on the same side, they are meshed and connected through a second synchronous belt pulley 211. At the center of the front end surface of the support device 22, a reduction motor 23 is arranged, and at the output end of the reduction motor 23, a driving bevel gear 24 is arranged. At the position near the middle of the outer end surface of the transmission shaft 213, a driven bevel gear 25 is arranged. At the upper part of the inner end surface of the support device 22, two guiding lead screws 29 are rotatably clamped. At the rear ends of the two guiding lead screws 29, second synchronous belt pulleys 27 are arranged, and between the two second synchronous belt pulleys 27, they are meshed and connected through a first synchronous belt 28. The inner end surface of the support device 22 is threadedly slidably connected with a threaded clamping seat 26 through two positioning lead screws 210, and the upper end surface of the support device 22 is threadedly slidably connected with a threaded push plate 212 through the guiding lead screws 29.

[0037] The support device 22 includes a bearing clamping seat 225. On the upper end surface of the bearing clamping seat 225, a fixed sliding seat 221 is arranged, and at the center of the inner end surface of the bearing clamping seat 225, a blanking guide groove 226 is opened. At the position of the lower end surface of the bearing clamping seat 225 corresponding to the blanking guide groove 226, a material guiding sliding plate 223 is arranged. At the four corners of the lower end surface of the bearing clamping seat 225, fixed guide shafts 224 are arranged, and at the position of the lower end surface of the bearing clamping seat 225 corresponding to the fixed guide shafts 224, support springs 222 are arranged.

[0038] The feeding device 3 includes a material guiding bin 36. At the top of the material guiding bin 36, there is a feeding slide plate 35. And at the outer end face of the material guiding bin 36 near the upper part, there is a fixed clamping seat 34. At both side parts of the material guiding bin 36, there are stepping motors 33. And at the output end of the stepping motor 33, there is a cross-shaped limiting plate 32. At the bottom of the side end face of the material guiding bin 36, there is a positioning rotating groove 31.

[0039] The driving bevel gear 24 is meshed with the driven bevel gear 25, which can effectively improve the stability of the internal transmission of the equipment.

[0040] The threaded push plate 212 is threadedly slidably connected to the inner end face of the fixed slide seat 221 through the guiding screw rod 29. The guiding screw rod 29 can drive the threaded push plate 212 to perform threaded displacement above the bearing clamping seat 225, thereby facilitating the rapid export of unqualified injection molded parts.

[0041] The bearing clamping seat 225 is slidably clamped to the upper end face of the weighing module 7 through the fixed guide shaft 224. And at the lower end face of the support spring 222, it is fixedly connected to the upper end face of the weighing module 7. The fixed guide shaft 224 can provide sufficient guiding basis for the bearing clamping seat 225, thereby improving the stability of the subsequent up and down displacement of the bearing clamping seat 225 above the weighing module 7, thus improving the accuracy of weighing the injection molded parts subsequently. At the same time, the four groups of support springs 222 have support stability, which can not only prevent the weighing efficiency from being low due to excessive rebound, but also prevent the overweight injection molded parts from directly impacting the weighing module 7, improving the protection of the weighing module 7.

[0042] The cross-shaped limiting plate 32 is slidably connected to the inside of the material guiding bin 36 through the positioning rotating groove 31. The positioning rotating groove 31 can provide sufficient guiding space for the rotation of the cross-shaped limiting plate 32, facilitating the subsequent two groups of reduction motors 23 to quickly and accurately feed the toy injection molded parts inside the material guiding bin 36 one by one.

[0043] Working principle: Before use, the staff can position a batch of required weighed and packaged toy injection molded parts inside the feeding slide plate 35. At the same time, the material guiding bin 36 and the cross-shaped limiting plate 32 at its bottom can support the injection molded parts, facilitating subsequent cyclic weighing and feeding. When feeding the injection molded parts one by one, the staff can synchronously start two sets of stepping motors 33. At this time, the stepping motors 33 can drive the cross-shaped limiting plate 32 at the bottom to rotate. When the two cross-shaped limiting plates 32 rotate, the gap formed by the rotation of the cross-shaped limiting plate 32 can pass through a set of injection molded parts. Subsequently, the two cross-shaped limiting plates 32 can continue to limit the injection molded parts inside the material guiding bin 36, enabling a single injection molded part to fall from inside the material guiding bin 36 to the upper part of the two threaded clamping seats 26. At this time, the injection molded part can move downward due to gravity. Subsequently, as the bearing clamping seat 225 presses down, the two weighing modules 7 can sense the weight of the injection molded part. When the weight of the injection molded part meets the weight range preset by the weighing module 7, the weighing of the injection molded part meets the standard. At this time, the weighing module 7 can start the reduction motor 23. At this time, the reduction motor 23 can drive the driven bevel gear 25 and the transmission shaft 213 to rotate synchronously through the driving bevel gear 24. The transmission shaft 213 can drive the two positioning lead screws 210 to rotate synchronously through the two first synchronous belt wheels 21 and the second synchronous belt wheel 211. The two positioning lead screws 210 can drive the two threaded clamping seats 26 to move centrifugally through the threaded connection with the threaded clamping seats 26, enabling the injection molded part to fall onto the upper part of the guide slide plate 223 and then be exported and collected. If the injection molded part does not meet the preset value of the weighing module 7, at this time, the weighing module 7 can start the servo motor 6. At this time, the servo motor 6 can drive the two guiding lead screws 29 to rotate synchronously through the second synchronous belt wheel 27 and the first synchronous belt 28. The two guiding lead screws 29 can drive the threaded push plate 212 to push out the injection molded parts on the upper part of the threaded clamping seats 26.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
