Detailed implementation manners

[0034] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation on the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] As Figure 1-13 shown, a loosening-proof stuffing machine includes a frame 1, a clamping module 2, a pressing module 3, a feeding and filling module 7, a bus bar 6, and a feed hopper 8; the clamping module 2 and the pressing module 3 are both arranged on the frame 1; a water baffle 12 is provided at the position where the feed hopper 8 is connected to the frame 1 to prevent water from entering the interior of the feed hopper 8;

[0036] As Figure 3 and 4 shown, the clamping module 2 includes a slide plate 21 and a locking device seat 22. The locking device seat 22 is provided with a sliding-in channel 221 and an embedding groove 222 that communicate with each other. The embedding groove 222 is located above the sliding-in channel 221. The slide plate 21 is fixedly connected to the locking device seat 22 so that the guiding channel 211 formed by the slide plate 21 faces the sliding-in channel 221; a fixed shaft 61 is provided on the side wall of the bus bar 6. The pressing module 3 is used to press the fixed shaft 61 into the embedding groove 222 so that the stuffing input port of the bus bar 6 is close to the output port of the feed hopper 8; wherein the cross-section of the fixed shaft 61 is a polygonal structure complementary to the inner wall of the embedding groove 222;

[0037] The bus bar 6 is provided with an insertion port and a stuffing output port. The feeding and filling module 7 extends into the bus bar 6 from the insertion port and faces the stuffing output port. The stuffing output port is provided with a discharge pipe 62 to facilitate the output of stuffing.

[0038] In the loosening-proof stuffing machine, since the slide plate 21 and the locking device seat 22 are fixedly connected structures, when the feeding and filling module 7 operates in the bus bar 6 to generate vibrations, it will not become loose like several swing arm parts 55 with traditional rotational connections. After the fixed shaft 61 of the bus bar 6 enters the sliding-in channel 221 along the guiding channel 211 and finally enters the embedding groove 222, the pressing module 3 acts on the bottom side of the bus bar 6 to press the fixed shaft 61 tightly in the embedding groove 222, and by means of the complementary polygonal structure, the rotation of the fixed shaft 61 is prevented, ensuring that the bus bar 6 is stable and does not become loose. When it is necessary to disassemble the bus bar 6, only need to loosen the pressing module 3, and the fixed shaft 61 can slide out along the sliding-in channel 221 and the guiding channel 211, thus facilitating disassembly. After disassembly, the bus bar 6 can be cleaned and maintained.

[0039] During use, the filling enters the manifold 6 from the feed hopper 8, and then passes through the feeding and filling module 7, so that the filling in the manifold 6 is sent out from the filling outlet of the manifold 6 and filled into the interior or on the surface of the dessert.

[0040] Preferably, as Figure 5 and 6 shown, the pressing module 3 includes a rocker 31, a connecting rod 32, a swing arm connecting block 33, a top shaft 34 and a top piece 35.

A top piece 35 is sleeved on the outer wall of the top shaft 34, and the top piece 35 faces the lower surface of the manifold 6.

[0041] Pull the other end of the rocker 31, and the middle of the rocker 31 will rotate, so that one end of the rocker 31 swings, which in turn drives the connecting rod 32 to swing, and then drives the swing arm connecting block 33 to swing; the top shaft 34 passes through the frame 1, and the frame 1 is provided with a guiding groove extending upward. The top shaft 34 passes through the guiding groove. Through the guiding action of the guiding groove, the top shaft 34 can move in the up and down directions, thereby driving the top piece 35 to move up and down. When the top piece 35 moves upward, the manifold 6 can be pressed, and when the top piece 35 moves downward, the manifold 6 can be released.

[0042] Specifically, the feeding and filling module 7 includes a connecting rod 71 and a feeding and filling member 72. One end of the connecting rod 71 is connected to one end of the feeding and filling member 72. The other end of the feeding and filling member 72 extends into the manifold 6 from the insertion port and faces the filling outlet.

[0043] The other end of the connecting rod 71 is connected to the linear feeding and filling driving module 4, so that the linear feeding and filling driving module 4 drives the feeding and filling member 72 to perform linear feeding movement, or the other end of the connecting rod 71 is connected to the dot feeding and filling driving module 5, so that the dot feeding and filling driving module 5 drives the feeding and filling member 72 to perform dot feeding movement.

[0044] This stuffing machine can switch between two structures of the linear feeding and filling driving module 4 and the dot feeding and filling driving module 5, so as to realize different feeding and filling driving modes.

[0045] The frame 1 is provided with a cantilever cover 11 for covering the linear feeding and filling drive module 4 and the dot feeding and filling drive module 5. A water baffle 12 is also provided around the linear feeding and filling drive module 4 and the dot feeding and filling drive module 5 to prevent water from entering the linear feeding and filling drive module 4 and the dot feeding and filling drive module 5. The frame 1 is provided with a shield 13 for covering the feeding and filling module 7, and a transparent hood 14 is provided in the middle of the shield 13 to facilitate observing the working condition of the feeding and filling module 7 from the outside.

A shaft inner gear sleeve 431 is provided at the end of the outer shaft 43. An inner tooth that cooperates with the cylindrical gear 421 is provided on one side of the end of the shaft inner gear sleeve 431 facing the end of the inner shaft 42. The cylindrical gear 421 is inserted into one side of the shaft inner gear sleeve 431;

[0047] A right-handed conical gear 44 is sleeved on the wall surface of the outer shaft 43. The other end of the connecting rod 71 of the feeding and filling module 7 is provided with a left-handed conical gear 45. The right-handed conical gear 44 and the left-handed conical gear 45 are perpendicular to each other and meshed;

[0048] As Figure 12 shows, the feeding and filling part 72 is a screw rod.

[0049] The first drive mechanism 41 is a motor. The output shaft of the first drive mechanism 41 is fixedly connected to the inner shaft 42 to drive the inner shaft 42 to rotate. When the inner shaft 42 rotates, it can drive the outer shaft 43 to rotate through the shaft inner gear sleeve 431, thereby driving the right-handed conical gear 44 to rotate. Then, the right-handed conical gear 44 drives the left-handed conical gear 45 to rotate, and further drives the connecting rod 71 to rotate. The connecting rod 71 will drive the feeding and filling part 72 to rotate in the bus bar 6, and use the characteristics of the screw rod to convey the filling to the filling outlet, realizing the linear feeding and filling method.

[0050] Preferably, as Figure 8As shown, the reverse conical gear 45 is rotatably connected to the frame 1. On one side of the reverse conical gear 45 near the other end of the connecting rod 71, there is a power output shaft 46. The power output shaft 46 is provided with a slot 461 and a through hole 462. The through hole 462 communicates with the slot 461. The other end of the connecting rod 71 is provided with a jack 711. After the other end of the connecting rod 71 is inserted into the slot 461, the jack 711 is aligned with the through hole 462, so that the other end of the connecting rod 71 is installed on the power output shaft 46 by inserting a pin 73 through the through hole 462 and the jack 711 at the same time.

[0051] Through the cooperation of the pin 73 with the jack 711 and the through hole 462, the purpose of detachable connection between the connecting rod 71 and the power output shaft 46 can be achieved. When the linear feeding and filling method is selected, the connecting rod 71 is installed in the power output shaft 46. When the dot feeding and filling method is selected, the connecting rod 71 is removed from the power output shaft 46.

[0052] Specifically, as Figure 7 、 10 and 11 show, the dot feeding and filling drive module 5 includes a second drive mechanism 51, an inner swing shaft 52, an outer swing shaft 53, an internal gear sleeve 54 and a swing arm member 55. The output end of the second drive mechanism 51 is provided with the inner swing shaft 52. Gear columns 521 are provided at the ends of the inner swing shaft 52 and the outer swing shaft 53. The inner wall of the internal gear sleeve 54 is provided with internal teeth. The gear columns 521 at the ends of the inner swing shaft 52 and the gear columns 521 at the ends of the outer swing shaft 53 are respectively inserted into the internal gear sleeve 54 from both sides of the internal gear sleeve 54, and the gear columns 521 are engaged with the internal teeth in the internal gear sleeve 54;

[0053] The outer swing shaft 53 is connected to one end of the swing arm member 55, and the other end of the swing arm member 55 is connected to the other end of the connecting rod 71;

[0054] As Figure 13 shows, the feeding and filling member 72 is a piston.

[0055] The second drive mechanism 51 is a cylinder. The output shaft of the second drive mechanism 51 is connected to the inner swing shaft 52 through the drive swing arm member 55. The forward and reverse rotations of the inner swing shaft 52 are realized by the extension and shortening of the telescopic shaft of the second drive mechanism 51. As Figure 7As shown, when the output shaft of the second driving mechanism 51 extends, it can push the inner swing shaft 52 to rotate clockwise, thereby driving the swing arm member 55 to swing away from the busbar 6. When the output shaft of the second driving mechanism 51 contracts, it can pull the inner swing shaft 52 to rotate counterclockwise, thereby driving the swing arm member 55 to swing towards the busbar 6, realizing the way of dot-shaped feeding and filling. In this way, by driving the feeding and filling member 72 to move through the swing arm member 55, the purpose of making the feeding and filling member 72 perform a piston-like movement in the busbar 6 can be achieved.

[0056] It should be noted that, as Figure 10 shown, an opening 551 is formed at the other end of the swing arm member 55, and a jack 711 is provided at the other end of the connecting rod 71, so that the other end of the connecting rod 71 can be installed at the other end of the swing arm member 55 by passing a pin shaft 74 through the opening 551 and the jack 711 simultaneously.

[0057] By the cooperation of the pin shaft 74 with the opening 551 and the jack 711, the purpose of detachable connection between the connecting rod 71 and the swing arm member 55 can be achieved. When the dot-shaped feeding and filling method is selected, the connecting rod 71 is installed on the swing arm member 55 through the pin shaft 74. When the linear feeding and filling method is selected, after removing the pin shaft 74, the connecting rod 71 is detached from the swing arm member 55.

[0058] Specifically, a pin hole 741 is formed at the end of the spool, and the pin hole 741 is adapted to the plug pin 73. After removing the plug pin 73 from the power output shaft 46, the plug pin 73 can be inserted into the pin hole 741, so as to prevent the plug pin 73 from detaching after being inserted into the opening 551 and the jack 711.
