[0050] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0051] Example 1: Reference Figures 1 to 3 As shown, a feeding device of a three-dimensional packaging device includes: a feeding box 1, a feeding cavity 11 is provided along the vertical direction of the feeding box 1, a through groove 13 is provided along the vertical direction of the side wall of the feeding box 1, a feeding port 12 is provided on the side wall at the bottom end of the feeding box 1, and a conveying mechanism is provided at the bottom end of the feeding box 1.

[0052] The conveying mechanism is provided with a feeding belt 2 along the opening direction of the feeding port 12, and the feeding belt 2 is driven to rotate by a motor.

[0053] Usually, the cartons that need to be film-coated are neatly stacked in the box. In this embodiment, during operation, Figure 3As shown, the cartons are stacked in the loading chamber 11, and the opening height of the feeding port 12 is higher than the height of the cartons and lower than the height of the two cartons. When loading, the worker can directly put multiple cartons neatly stacked in the box into the loading chamber 11. When loading, the feeding belt 2 rotates, driving the bottom cartons to move toward the feeding port 12, and the cartons are sent out of the loading box 1 by the feeding port 12. The cartons fall onto the conveyor belt of the three-dimensional packaging device 7, and then the three-dimensional packaging device 7 performs three-dimensional film packaging on the cartons. The setting of the through groove 12 can facilitate workers to put cartons in the loading chamber 11.

[0054] Example 2: Reference Figures 1 to 9 As shown, the structure of this embodiment is similar to that of embodiment 1, except that the structure of the conveying mechanism is different. Since the surface of the uncoated carton has a certain viscosity, when the conveyor belt delivers the carton, the friction between the lowest carton and the conveyor belt is less than the friction between the lowest carton and the upper carton, causing slippage between the carton and the conveyor belt, so that the carton cannot be delivered from the loading chamber 11. Therefore, the conveying mechanism is improved, and the specific improvement measures are as follows:

[0055] The conveying mechanism includes a material tapping mechanism 4 arranged on the side of the bottom of the loading box 1, a material tapping box 3 is arranged on the side wall of the bottom of the loading box 1, the material tapping mechanism 4 is arranged in the material tapping box 3, the material tapping mechanism 4 includes a material tapping shaft 41, a material tapping rod 42 is arranged on the material tapping shaft 41, and a material tapping groove 14 is arranged on the peripheral wall of the bottom of the loading box 1 for facilitating the material tapping rod 42 to rotate into the loading cavity 11.

[0056] A guide ring groove 31 is provided at the top of the material shifting box 3, and the material shifting rod 42 includes a first shifting rod 421 fixedly arranged with the material shifting shaft 41, a sliding hole is provided in the first shifting rod 421, and a second shifting rod 422 is slidably arranged in the sliding hole, and a contraction spring 424 is connected between the second shifting rod 422 and the bottom of the sliding hole. The contraction spring 424 has a contraction force to maintain the tendency of pulling the second shifting rod 422 toward the output shaft 611, and a guide block 423 is provided on the second shifting rod 422, and the guide block 423 is slidably arranged in the guide ring groove 31.

[0057] The guide ring groove 31 includes a first arc segment 311 and a second arc segment 312. The first arc segment 311 is arranged on a side away from the loading box 1, and the second arc segment 312 is arranged on a side close to the loading box 1; the first arc segment 311 and the second arc segment 312 have the same radius, and the opening direction of the second arc segment 312 is opposite to the opening direction of the second arc segment 312; the first arc segment 311 is a major arc, and the second arc segment 312 is a minor arc, and the connecting line between the two ends of the second arc segment 312 is parallel to the feeding direction of the feeding port 12.

[0058] In this embodiment, in order to enable the paper box to be conveniently and efficiently sent out from the loading chamber 11 through the conveying mechanism, the conveying mechanism is modified. The working principle is that the material-pickup shaft 41 is driven by the motor to rotate the material-pickup shaft 41, and the rotation of the material-pickup shaft 41 drives the material-pickup rod 42 to rotate. When the material-pickup rod 42 rotates through the material-pickup groove 14 and enters the loading chamber 11, the bottom paper box is pulled out from the feeding port 12; in addition, when the material-pickup shaft 41 rotates, it drives the first lever 421 to rotate. Since a guide block 423 is provided on the second lever 422, the guide block 423 will move along the guide ring groove 31 with the rotation of the first lever 421. When the guide block 423 moves to the second arc segment 312, the end of the guide block 423 will not make a circular motion around the material-pickup shaft 41, but will be guided by the second arc segment 312, as shown in FIG. Figure 8 As shown by the dotted line, the material discharging direction of the feeding port 12 is similar to a straight arc motion, so that the paper box can be pushed more stably. At the same time, due to the effect of the guide block 23, the material lever 42 can be supported.

[0059] Example 3: Reference Figures 1 to 9 As shown, this embodiment is similar in structure to the embodiment 2, except that, in order to enable the material-dispensing mechanism to more stably push the paper box out of the loading chamber 11, two material-dispensing boxes 31 are provided, and the two material-dispensing boxes are provided on both sides of the width direction of the loading box 1.

A slider is provided at the bottom of the loading box 1. A slide groove cooperating with the slider is provided on the bottom box 5. The slide groove is provided along the width direction of the feeding port 12, so that the material digging box 3 can slide in the width direction of the feeding port 12. The sliding direction of the loading box 1 is perpendicular to the feeding direction of the feeding port 12.

A bottom box slider 52 is arranged in the bottom box slide groove 51, and the output motor 61 is fixedly arranged in the bottom box slider 52; a first output wheel 612 and a second output wheel 613 are arranged on the output shaft 611 of the output motor 61, the first output wheel 612 is fixedly arranged on the output shaft 611, and the second output wheel 613 is rotatably arranged on the output shaft 611, a first side gear 614 is arranged on the side wall of the first output wheel 612 close to the second output wheel 613, and a second side gear 615 is arranged on the side wall of the second output wheel 613 close to the first output wheel 612, and a first side gear 614 is arranged between the first side gear 614 and the second side gear 615. A transmission side gear 616 meshing with the two is arranged, and a mounting shaft 521 is arranged on the bottom box slider 52, and the transmission side gear 616 is rotatably arranged on the mounting shaft 521; the transmission chain includes a first chain 62 and a second chain 63, and the material-pickup shafts 41 in the two loading boxes are respectively the first material-pickup shaft 411 and the second material-pickup shaft 412, and the first material-pickup shaft 411 is fixedly provided with a first material-pickup wheel 413, and the first material-pickup wheel 413 is a gear structure, and the first material-pickup wheel 412 and the first output wheel 612 are driven by the first chain 62, and the second material-pickup wheel 414 is fixedly provided on the second material-pickup wheel shaft 412, and the second material-pickup wheel 414 is a gear structure, and the second material-pickup wheel 414 and the second output wheel 613 are driven by the second chain 63;

[0063] The first connecting rod 64, both ends of the first connecting rod 64 are provided with a rotating sleeve, the rotating sleeve at one end of the first connecting rod 64 is sleeved on the output shaft 611, and the rotating sleeve at the other end of the first connecting rod 64 is sleeved on the first material-selecting shaft 411, one end of the first connecting rod 64 is rotatably connected to the output shaft 611 through the rotating sleeve, and the other end of the first connecting rod 64 is rotatably connected to the first material-selecting shaft 411 through the rotating sleeve;

[0064] The second connecting rod 65, both ends of the second connecting rod 65 are provided with a rotating sleeve, the rotating sleeve at one end of the second connecting rod 65 is sleeved on the output shaft 611, and the rotating sleeve at the other end of the second connecting rod 65 is sleeved on the second material shifting shaft 412, one end of the second connecting rod 65 is rotatably connected to the output shaft 611 through the rotating sleeve, and the other end of the second connecting rod 65 is rotatably connected to the second material shifting shaft 412 through the rotating sleeve.

[0065] The side wall of the bottom box 5 is fixedly provided with an adjusting cylinder 53, the output end of which is fixedly connected to the bottom box slider 52, and the output end of which can push the bottom box slider 52 to slide along the bottom box slide 51. The bottom box slide 51 is arranged on the mid-perpendicular line of the line connecting the first material-dispensing rotating shaft 411 and the second material-dispensing rotating shaft 412.

[0066] The working principle of this embodiment is as follows: the rotation of the output motor 61 drives the output shaft 611 to rotate, and drives the first output wheel 612 to rotate. The rotation of the first output wheel 612 is driven by the first chain 62 to rotate the first material-pickup wheel 413. The first material-pickup wheel 413 drives the first material-pickup shaft 411 to rotate, thereby driving the material-pickup rod 42 on the first material-pickup shaft 411 to rotate, and the material-pickup rod 42 rotates to pull the paper box out of the loading chamber 11; in addition, the working principle of the second material-pickup shaft 412 to realize the rotation is that when the first output wheel 612 rotates, the first output wheel 612 drives the first material-pickup shaft 411 to rotate. The dynamic transmission side gear 616 rotates, so that the transmission side gear 616 drives the second output wheel 613 to rotate, and the transmission side gear 616 makes the rotation direction of the second output wheel 613 opposite to the rotation direction of the first output wheel 612, and then the second output wheel 613 drives the second material tapping wheel 414 to rotate through the second chain 63, and the second material tapping wheel 414 drives the second material tapping shaft 412 to rotate, and the second material tapping shaft 412 drives the material tapping rod 42 connected thereto to rotate, so that the two material tapping rods 42 simultaneously push out the paper box on both sides of the paper box, making the paper box tapping efficiency higher.

[0067] At the same time, when it is necessary to adjust the width between the guide plates 15 according to the size of the paper box, the bottom box slider 52 is driven to slide along the bottom box slide groove 51 by adjusting the cylinder 53, so that the output motor 61 slides along the bottom box slide groove 51, and the output shaft 611 of the output motor 61 pulls the two loading boxes 1 closer to or away from each other through the first connecting rod 64 and the second connecting rod 65, so that the distance between the two guide plates 15 can be easily adjusted without affecting the transmission.

[0068] In this embodiment, two material-dispensing boxes 3 are arranged on both sides of the loading box 1, so that when the paper box is pushed out of the loading chamber 11, the material-dispensing boxes 3 on both sides can act at the same time, so that the two material-dispensing rods 42 can stably displace the paper box at the same time; at the same time, by arranging the adjusting cylinder 53, the distance between the two material guide plates 15 can be adjusted, so that paper boxes of different widths can be conveniently placed in the loading chamber 11. In addition, the structure in this embodiment is an independent structure, which means that the loading box 1, the bottom box 5, and the material-dispensing box 3 are an independent device, so that the loading device of a three-dimensional packaging device of the present invention can be easily moved and placed on the side of various conveyor belts, which is very convenient to install and use.
