It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0015] The following is in conjunction with the instruction manual appendix. Figure 1-10 The present invention will be further described below.

[0016] A feeding device for a packaging machine includes a frame 1, a discharge platform assembly 4, a lifting assembly 5, a conveyor belt 2, and a pushing assembly 3. The front end of the frame 1 is provided with a conveyor belt 2, the rear end of the conveyor belt 2 is provided with a lifting assembly 5, and the discharge platform assembly 4 is provided at the rear end of the lifting assembly 5. The discharge platform assembly 4 includes a toothed guide 41 and a movable toothed platform 42. The toothed guide 41 is comb-shaped and fixedly mounted on the frame 1. The movable toothed platform 42 is "7"-shaped and is a comb-shaped structure adapted to the comb shape of the toothed guide 41. The movable toothed platform 42 also includes an adjusting wheel 421, a sliding screw 422, a slider 423, a guide rail 424, an adjusting arm 425, a bevel gear 246, and a bevel gear 427. One end of the adjusting arm 425 is fixedly connected to the movable toothed platform 427. At the bottom of the gear shaping table 42, the other end of the adjusting arm 425 is connected to the slider 423. The top of the slider 423 is slidably mounted on the guide rail 424. The slider 423 has a hole that matches the sliding screw 422. The tail end of the sliding screw 422 is provided with a bevel gear 426. The tail end of the adjusting wheel 421 is also provided with a bevel gear 427 that matches the bevel gear 426 at the tail end of the sliding screw 422. The adjusting wheel 421 is used to adjust the change in the axial length of the discharge table assembly 4. The lifting assembly 5 is equipped with a package inserting tooth platform 55, which is also comb-shaped. The package inserting tooth platform 55 meshes with the bottom inserting teeth of the movable inserting tooth platform 42. When the movable inserting tooth platform 42 is axially adjusted, the axial dimension of the platform surface of the movable inserting tooth platform 42 changes. Rotating the adjusting wheel 421 can drive the movable inserting tooth platform 42 to move horizontally. When packaging packages 8 of different widths, adjusting the movable inserting tooth platform 42 changes the distance between it and the conveyor belt 21, that is, the platform size of the package inserting tooth platform 55 can adapt to packages 8 of different sizes and specifications.

[0017] Furthermore, the lifting assembly 5 also includes a second base 51, a fixed plate 52, a transmission gear 53, a lifting slide rail 54, and a lifting rod 56. The second base 51 is fixedly mounted on the bottom surface of the frame 1. The fixed plate 52 is fixedly mounted on the top surface of the second base 51. The lifting slide rail 54 is located at the front end of the fixed plate 52. The transmission gear 53 is located on the side of the fixed plate 52. The lifting rod 56 is movably mounted on the lifting slide rail 54. The side of the lifting rod 56 has a toothed groove that meshes with the transmission gear 53. The transmission gear 53 is connected to a power mechanism. The top of the lifting rod 56 is fixedly mounted on a bag-holding toothed platform 55. The lowest horizontal height of the bag-holding toothed platform 55 is the same as the horizontal height of the conveyor belt 2, and the highest horizontal height of the bag-holding toothed platform 55 is the same as the horizontal height of the movable toothed platform 42. The power mechanism drives the transmission gear 53 to reciprocate on the toothed groove to achieve the lifting and lowering of the lifting assembly.

[0018] Furthermore, the material pushing assembly 3 includes a base 31, a rotating shaft 32, a swing arm 33, a transmission arm 34, a sliding plate 35, a pushing track 36, and a push plate 37.

The rotating shaft 32 passes through the side of the upright plates and is connected to the bottom surface of the swing arm 33 via a flange. The bottom end of the transmission arm 34 is movably mounted on the top surface of the swing arm 33. The top end of the transmission arm 34 is fixedly connected to the sliding plate 35. The sliding plate 35 is slidably mounted on the pushing track 36, and the front end of the sliding plate 35 has a push plate 37. The transmission mechanism connects the swing arm 33 via a transmission rod, causing it to reciprocate and thus drive the push plate 37 to perform the material pushing operation. The transmission mechanism connecting the swing arm 33 via a transmission rod is a common technical solution in this field and will not be elaborated further here.

[0019] Furthermore, a pair of baffles 7 are also mounted on the upper surface of the conveyor belt 2. Each baffle 7 has at least one baffle adjustment assembly 71 on one side.

The bracket 711 is mounted on the side of the conveyor belt 2, and the adjustment rod 712 passes through the side of the bracket 711. An adjustment hole is opened at the top of the bracket 711, and several holes matching the adjustment hole are opened on the surface of the adjustment rod 712. The adjustment knob 713 is located at the top of the bracket 711 and passes through the adjustment hole and the holes. One end of the adjustment rod 712 is connected to the baffle 7. The spacing between the baffles 7 can be adjusted according to the width of the packaged item 8. To adjust, remove the adjustment knob 713 to adjust the position of the adjustment rod 712, and then put the adjustment knob 713 back in.

[0020] Furthermore, the upper surface of the discharge platform assembly 4 is provided with an adjusting guide plate 43. The adjusting guide plate 43 includes a pair of guide plates 431 and an adjusting slider 432. The adjusting slider 432 is located at the tail of the guide plate 431, and a screw mounting slot is provided on the adjusting slider 432. The adjusting slider is detachably mounted on the surface of the discharge platform assembly 4. By moving the adjusting slider 432 and fixing it to the tooth guide 41 with screws passing through the screw mounting slot, it can accommodate different models of products.

[0021] Furthermore, the frame 1 is also equipped with a feeding and pressing assembly 6, which includes a U-shaped base 61, a lifting screw 62, an adjusting wheel 63, a cantilever 64, and a feeding pressure plate 65. The U-shaped base 61 is fixedly mounted on the frame 1. The bottom end of the lifting screw 62 is located on the bottom surface of the U-shaped base 61, and the top end of the lifting screw 62 penetrates the top surface of the U-shaped base 61. The top end of the lifting screw 62 is connected to the adjusting wheel 63. The tail end of the cantilever 64 is sleeved on the lifting screw 62, and the top end of the cantilever 64 is fixedly connected to the feeding pressure plate 65. The feeding pressure plate 65 is located below the push plate 37, and the front end of the feeding pressure plate 65 is at the same horizontal plane as the front end of the conveyor belt 21. By rotating the adjusting wheel 63, the height of the cantilever 64 can be adjusted via the lifting screw 62, thereby adjusting the height of the feeding pressure plate 65 to accommodate packages 8 of different heights.
