The film barrel is vertically arranged, and a material transfer channel is arranged in the film barrel. The upper end of the material transfer channel is connected to the feeding outlet of the feeding device. The longitudinal sealing mold is arranged on the inner side of the outer periphery of the film barrel, the traction wheel is arranged below the longitudinal sealing mold, and the transverse sealing mold is arranged below the lower end of the film barrel. It is characterized in that: the feeding device includes an automatic turning feeding device for toothbrushes and an automatic turning feeding device for toothpaste.

The feeding hopper 11 and the storage tray 12 are fixedly connected to the support frame 1, and nuts are transported to the feeding hopper 11 for temporary storage by a conveyor belt. The storage tray 12 is provided with a plurality of first guide rails 16 along the circumferential direction, and the storage tray 12 is provided with a plurality of weighing barrels 17 corresponding to the first guide rails 16. The ends of the first guide rails 16 away from the weighing barrels 17 correspond to the lower end of the feeding hopper 11.

The spiral plate 15 can push the nuts in the feeding hopper 11 to the first guide rail 16 and the second guide rail 18. The width of the first guide rail 16 is greater than the width of the second guide rail 18. Nuts are quickly added to the weighing barrel 17 through the first guide rail 16, and the second guide rail 18 can arrange the nuts one by one. The storage tray 12 is provided with a sealing mechanism 3, and the sealing mechanism 3 includes a sealing cover 36, and the sealing cover 36 is adapted to the lower end of the weighing barrel 17.

[0041] Reference Figure 2 and Figure 3 The sealing cover 36 is provided with a weighing sensor for weighing nuts, and the weighing sensor can achieve the effect of weighing the nuts in the weighing barrel 17. When the weight of the nuts in the weighing barrel 17 reaches or exceeds the first preset value, the weight of the first preset value is less than the weight required for packaging the nuts, and the storage tray 12 is provided with a joint mechanism 7.

[0042] Reference Figure 4 and Figure 5 The joint mechanism 7 includes a first cross bar 72, a first cylinder 74, a sliding rod 75 and two limit slide rails 73. The two limit slide rails 73 are fixed in the material storage tray 12. The two ends of the first cross bar 72 along the length direction are respectively slidably connected to the two limit slide rails 73. The first cylinder 74 is fixedly connected to the material storage tray 12, and the output end of the first cylinder 74 is fixedly connected to the sliding rod 75. The output end of the first cylinder 74 extends to push the sliding rod 75 upward. The sliding rod 75 has a first sliding groove. The first cross bar 72 is slidably connected to the sliding rod 75 through the sliding groove, and the sliding rod 75 pushes the first cross bar 72 to move.

The storage tray 12 is provided with a blocking mechanism 2, and the blocking mechanism 2 includes a rotating plate 24, which is rotatably connected to the end of the first guide rail 16 away from the feeding hopper 11 and conflicts with the protective tube 21. The sliding rod 75 pushes the lifting plate 78 through the vertical rod 77, so that the lifting plate 78 pushes the rotating plate 24 upward in advance, which can reduce the speed at which the nuts in the first guide rail 16 fall excessively into the weighing barrel 17, and improve the accuracy of nut filling.

[0044] Reference Figure 4 and Figure 5The storage tray 12 is provided with a driving mechanism 6, which includes a second motor 61 and a first gear 62. The second motor 61 is fixedly arranged in the storage tray 12, and the output shaft of the second motor 61 is fixedly connected to the first gear 62. The output shaft of the second motor 61 drives the first gear 62 to rotate. The blocking mechanism 2 also includes a protective tube 21, a first rack 22, and a second gear 23.

[0045] Reference Figure 4 and Figure 5 , the first rack 22 is fixedly connected to the protective tube 21, and the second gear 23 is rotatably connected to the storage tray 12 and meshes with the first rack 22. The coupling mechanism 7 also includes a third gear 71, which is rotatably connected to the first crossbar 72. The first crossbar 72 pushes the third gear 71 to mesh with the first gear 62 and the second gear 23 at the same time. An elastic component is provided between the protective tube 21 and the storage tray 12. When the third gear 71 conflicts with the second gear 23, the second gear 23 will drive the protective tube 21 to move slightly downward through the first rack 22. The elastic component can support and buffer the protective tube 21.

[0046] Reference Figure 4 and Figure 5 The second motor 61 drives the third gear 71 to rotate through the first gear 62, and the third gear 71 further drives the second gear 23 to rotate. The third gear 71 drives the protective cylinder 21 to rise through the first rack 22, so that the upper end of the protective cylinder 21 is higher than the first guide rail 16, which can prevent the nuts on the first guide rail 16 from falling into the weighing barrel 17. At the same time, the protective cylinder 21 further drives the rotating plate to rotate, so that the rotating plate 24 blocks the nuts on the first guide rail 16.

[0048] Reference Figure 4 and Figure 6 The two ends of the bottom plate 41 along the length direction are fixedly connected to the blocking plate 42 and the blocking block 43 respectively. The blocking plate 42 and the blocking block 43 are both penetrated by the second guide rail 18 and are slidably connected to the second guide rail 18. The blocking plate 42 is provided with a material passing groove 46. When the push plate 64 pushes the bottom plate 41 to move vertically upward, the protective cylinder 21 also gradually moves upward, and the bottom plate 41 pushes the blocking plate 42 and the blocking block 43 to move upward. The nuts that collide with the blocking plate 42 will fall into the weighing bucket 17 through the material passing groove 46 (refer to Figure 2 ), the blocking block 43 will block other nuts on the second guide rail 18.

[0049] Reference Figure 4 and Figure 6 The two ends of the bottom plate 41 along the width direction are respectively fixedly connected with two limit rods 44, both limit rods 44 are penetrated by the second guide rail 18 and are slidably connected with the second guide rail 18, and two limit springs 45 are respectively sleeved on the corresponding limit rods 44, and the two ends of the limit springs 45 along the length direction are respectively fixedly connected with the second guide rail 18 and the bottom plate 41. When the bottom plate 41 moves upward, the bottom plate 41 and the second guide rail 18 cooperate to squeeze the limit springs 45, so that the limit springs 45 are deformed.

[0050] Reference Figure 4 and Figure 6 When the push plate 64 falls back, the bottom plate 41 moves down synchronously with the push plate 64 under the action of the limit spring 45, the blocking plate 42 falls back under the pull of the bottom plate 41 and conflicts with the second guide rail 18, the blocking block 43 moves down and separates from the nut, and the nut continues to conflict with the blocking plate 42, achieving the effect of nuts falling one by one, which is beneficial to reduce the deviation between the weighed mass of the nuts and the preset mass, and can improve the filling accuracy of the nuts.

[0051] Reference Figure 3 and Figure 4 The sealing mechanism 3 further includes a second cylinder 31, a first slider 32, a second connecting rod 33, a third connecting rod 34 and a support plate 35. The second cylinder 31 is fixedly arranged in the storage tray 12, and the output end of the second cylinder 31 is fixedly connected to the first slider 32. The first slider 32 is slidably connected to the storage tray 12 and is rotatably connected to the second connecting rod 33. When the weight of the nuts in the weighing barrel 17 reaches or slightly exceeds the weight required for packaging the nuts, the output shaft of the second motor 61 stops rotating, and the output end of the second cylinder 31 extends to push the first slider 32 to move.

[0052] Reference Figure 3 and Figure 4The second connecting rod 33 is rotatably connected to the third connecting rod 34, the first slider 32 drives the third connecting rod 34 to rotate through the second connecting rod 33, the support plate 35 is rotatably connected to the storage tray 12 and fixedly connected to the third connecting rod 34, the third connecting rod 34 pushes the support plate 35 to rotate, the support plate 35 is fixedly connected to the sealing cover 36, and the sealing cover 36 is adapted to the lower end of the weighing bucket 17. The support plate 35 pulls the sealing cover 36 to separate from the storage tray 12, and the support frame 1 is fixedly provided with a collecting bucket 19, which corresponds to the weighing bucket 17, and the nuts in the weighing bucket 17 fall into the collecting bucket 19.

[0053] Reference Figure 3 and Figure 4 After the nuts in the weighing barrel 17 fall into the collecting bucket 19, the sealing mechanism 3 reseals the weighing barrel 17. The first cylinder 74 drives the first crossbar 72 to move downward, so that the third gear 71 is separated from the second gear 23, and the protective cylinder 21 gradually falls back under the action of gravity, and the first guide rail 16 can add nuts into the weighing barrel 17.

[0054] Reference Figure 1 and Figure 2 The support frame 1 is provided with a packaging mechanism 5, which includes a feed tube 51, a folding plate 52, a feeding assembly 53, a first sealing mechanism 54 and a second sealing mechanism 55. The folding plate 52 is sleeved on the feed tube 51 and is fixedly connected to the support frame 1. The feeding assembly 53 transports the plastic film to the folding plate 52 for folding, and wraps the plastic mold around the feed tube 51. The first sealing mechanism 54 and the second sealing mechanism 55 are both arranged on the support frame 1, and the first sealing mechanism 54 performs transverse sealing on the plastic film.

[0055] Reference Figure 1 and Figure 2 The second sealing mechanism 55 seals the plastic film longitudinally, and the feeding tube 51 corresponds to the lower end of the collecting bucket 19. At this time, the nuts fall into the plastic mold through the feeding tube 51, and the second sealing mechanism 55 seals the plastic mold again to achieve the packaging effect of the nuts. The feeding assembly 53, the first sealing mechanism 54 and the second sealing mechanism 55 are all related to the prior art, and will not be described in detail in this embodiment.

[0056] The implementation principle of a nut filling device in the embodiment of the present application is as follows: nuts are transported to the feeding hopper 11 for temporary storage by a conveyor belt. The output shaft of the first motor 13 rotates intermittently to drive the feeding rod 14 and the spiral plate 15 to rotate, and the spiral plate 15 pushes the nuts in the feeding hopper 11 to the first guide rail 16 and the second guide rail 18. The width of the first guide rail 16 is greater than the width of the second guide rail 18. Nuts are quickly added to the weighing barrel 17 through the first guide rail 16, and the second guide rail 18 can arrange the nuts one by one.

[0057] The weighing sensor can be used to weigh the nuts in the weighing barrel 17. When the weight of the nuts in the weighing barrel 17 reaches or exceeds the first preset value, the output end of the first cylinder 74 extends to push the sliding rod 75 upward, and the sliding rod 75 pushes the first cross bar 72 to move. The output shaft of the second motor 61 drives the first gear 62 to rotate, and the first cross bar 72 drives the third gear 71 to mesh with the first gear 62 and the second gear 23 at the same time. The second motor 61 drives the third gear 71 to rotate through the first gear 62, and the third gear 71 further drives the second gear 23 to rotate. The third gear 71 drives the protective tube 21 to rise through the first rack 22, so that the upper end of the protective tube 21 is higher than the first guide rail 16, which can prevent the nuts on the first guide rail 16 from falling into the weighing barrel 17. At the same time, the protective tube 21 further drives the rotating plate to rotate, so that the rotating plate 24 blocks the nuts on the first guide rail 16.

[0058] The first gear 62 drives the push plate 64 to reciprocate through the first connecting rod 63. When the push plate 64 pushes the bottom plate 41 to move vertically upward, the protective tube 21 also gradually moves upward, and the bottom plate 41 pushes the blocking plate 42 and the blocking block 43 to move upward. The nuts that collide with the blocking plate 42 will fall into the weighing barrel 17 through the material trough 46, and the blocking block 43 will block other nuts on the second guide rail 18. When the bottom plate 41 moves upward, the bottom plate 41 and the second guide rail 18 cooperate to squeeze the limit spring 45, causing the limit spring 45 to deform.

[0059] When the push plate 64 falls back, the bottom plate 41 moves down synchronously with the push plate 64 under the action of the limit spring 45, the blocking plate 42 falls back under the pull of the bottom plate 41 and contacts the second guide rail 18, the blocking block 43 moves down and separates from the nut, and the nut continues to contact the blocking plate 42, achieving the effect of nuts falling one by one, which is beneficial to reduce the deviation between the weighed mass of the nuts and the preset mass, and can improve the filling accuracy of the nuts.

[0060] The embodiment of the present application also discloses a method for using a nut filling device, including: nuts are added from a feeding hopper 11 and fall onto a first guide rail 16 and a second guide rail 18; the nuts on the first guide rail 16 fall rapidly into a weighing barrel 17 under the push of a spiral plate 15; when the mass in the weighing barrel 17 reaches a first preset value, a blocking mechanism 2 prevents the nuts on the first guide rail 16 from falling into the weighing barrel 17; the nuts on the second guide rail 18 fall into the weighing barrel 17 one by one under the action of a limiting mechanism 4; when the mass in the weighing barrel 17 reaches the mass required for packaging the nuts, a sealing mechanism 3 opens the lower end of the weighing barrel 17 so that the nuts can fall into the packaging mechanism 5 for packaging, thereby achieving the filling and packaging of the nuts.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
