DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figures 1 to 7 , is an improved laminating machine box pushing device as the best embodiment of the utility model, comprising:

[0040] The conveyor belt mechanism 10 includes a frame 11, a belt surface 12, and a conveying motor 13 that drives the belt surface 12 to circulate along the frame 11. In this embodiment, a lower material level 14 is formed along the conveying path of the belt surface 12, and the lower material level 14 is specifically arranged on the horizontal side of the discharge end of the conveyor belt. In addition, in this embodiment, the frame 11 is located on one side of the belt surface 12 to form a baffle structure that is higher than the belt surface 12, and the baffle structure forms an outlet side flush with the belt surface 12 on one side of the lower material level 14 (not marked in the figure), thereby facilitating the smooth unloading of the packaging box from this position.

[0041] The unloading stop mechanism 20 is arranged at one side of the unloading position 14, and includes a pair of adjustment seats 21 distributed in sequence along the conveying direction of the belt surface 12 and a first horizontal driving device 22 driving the two adjustment seats 21 to move toward each other along the conveying direction of the belt surface 12. The adjustment seat 21 away from the feeding position of the conveyor belt mechanism 10 is provided with a stop rod 23 extending horizontally to the upper end of the belt surface 12. The two adjustment seats 21 enclose a box pushing channel 24 for the packaging box to be embedded and flush with the belt surface 12;

[0042] The first box pushing mechanism 30 includes a push rod 31 and a second horizontal driving device 32 driving the push rod 31 to move in a direction close to or away from the box pushing passage 24;

[0043] The second box pushing mechanism 40 includes a pair of parallel arranged forks 50, a fork device 60 for driving the forks 50 to move toward each other along the conveying direction of the belt surface 12, a vertical driving device 70 for driving the forks 50 to move vertically, and a third horizontal driving device 80 for driving the forks 50 to move in a direction close to or away from the box pushing channel 24.

[0044] Preferably, Figure 2 , 3 As shown, the first horizontal driving device 22 includes a first guide rail 221 parallel to the belt surface 12, a pair of first sliders 222 slidably arranged on the first guide rail 221, a pair of linear first racks 223 and a first driving motor 224. The two adjustment seats 21 are respectively arranged on a first slider 222 and a fixing plate 211 is extended downward along both sides of the first guide rail 221. The two linear first racks 223 are respectively fixed on the fixing plate 211 in parallel and the sides with the tooth grooves are arranged opposite to each other. The end of the first driving motor 224 is provided with a first driving gear 225, and the first driving gear 225 is meshed between the two oppositely arranged first racks 223. Specifically, a pair of support rods 226 are symmetrically arranged at the bottom of both ends of the first guide rail 221, which are used to move the first guide rail 221 as a whole. Fixed to the working surface to be installed, the two first racks 223 are respectively arranged at positions of the two fixing plates 211 beyond the bottom of the first guide rail 221 and are distributed parallel to the first guide rail 221, and the two first racks 223 extend in opposite directions. The first drive motor 224 is arranged at the lower end of the first guide rail 221 through the motor mounting plate 227 and is located between the two support rods 226. Therefore, when the first drive motor 224 is working, it drives the first drive gear 225 to rotate, and the two first racks 223 meshing with the first drive gear 225 move linearly in opposite directions, thereby driving the two adjustment seats 21 to realize opposite movements on the first guide rail 221, so as to facilitate the adjustment of the spacing of the box pushing channel 24 between the two adjustment seats 21, that is, to facilitate the adaptive adjustment of the box width.

[0045] Further, such as Figure 3As shown, a fitting groove 212 is recessed on one side where the two adjustment seats 21 are close to each other, and a box pushing channel 24 is formed between the two fitting grooves 212. Thus, the box pushing channel 24 formed by the fitting grooves 212 can guide the packaging box along the inner wall of the fitting groove 212 when the packaging box is pushed in, so that it can smoothly transition into the corresponding packaging film bag.

[0046] Preferably, Figure 1 , 4 As shown, the second horizontal driving device 32 includes a second guide rail 321 distributed along the length direction of the stop rod 23 and located on one side of the belt surface 12, a second slider 322 slidably arranged on the second guide rail 321, a first connecting seat 323 detachably fixed to the second slider 322, a first driving belt 324 cyclically transmitted along the length direction of the second guide rail 321, and a second driving motor 325 for driving the first driving belt 324 to cyclically transmit, the second driving motor 325 and the first driving belt 324 are synchronous motors and synchronous belts respectively, one side of the first connecting seat 323 is detachably fixed to the first driving belt 324, and the push rod 31 is arranged on the first connecting seat 323. The first drive belt 324 is clamped on one side of the first connecting seat 323 and is parallel to the transmission direction of the belt surface 12. In this embodiment, a clamping channel 326 is formed on one side of the first connecting seat 323. The first driving belt 324 passes through the clamping channel 326 and is clamped and fixed by the two side walls of the clamping channel 326. Therefore, when the second driving motor 325 is working, it drives the first driving belt 324 to circulate. During the transmission process, the first driving belt 324 drives the first connecting seat 323 to translate along the length direction of the second guide rail 321, thereby driving the push rod 31, so that it can realize reciprocating movement along the length direction of the stop rod 23, and further achieve the purpose of pushing the packaging box from the belt surface 12 to the box pushing channel 24.

[0047] In particular, in this embodiment, the stopper rod 23 is disposed in close contact with the belt surface 12, and the push rod 31 is disposed in close contact with the upper end of the stopper rod, thereby facilitating the pushing process of the packaging box.

[0048] Preferably, Figure 2 , 4 As shown, a vertical side plate 34 is provided on the side of the second guide rail 321 away from the unloading stop mechanism 20, and the side plate 34 is located above the second guide rail 321 and is provided with a first position detection device 35 for detecting whether the first connecting seat 323 is in place. In this embodiment, the first position detection device 35 is a photoelectric sensor, so that when the first connecting seat 323 moves to the bottom thereof, it is sensed, thereby facilitating the detection of the initial position of the push rod 31.

[0049] Furthermore, a square toggle block 33 is provided at the end of the push rod 31. The cross-section of the toggle block 33 is square and its area is larger than the cross-sectional area of ​​the push rod 31. In this embodiment, the position of the toggle block 33 is opposite to the center line of the two adjustment seats 21. Therefore, the packaging box can be easily pushed by the toggle block 33 so that it can fall smoothly into the box pushing channel 24.

[0050] Preferably, Figure 5 , 6 As shown, the fork device 60 includes a fork plate 61, a fork motor 62, a third guide rail 63, a pair of third sliders 64 sliding on the third guide rail 63, a pair of second connecting seats 65 and a pair of linear second racks 66, the two forks 50 are vertically fixed to the bottom of the two second connecting seats 65, the two second racks 66 are respectively and parallelly fixed at different heights on the top of the two second connecting seats 65, the two third sliders 64 are fixed at the same horizontal height position of the second connecting seats 65, the output shaft of the fork motor 62 is transmission-connected to the second drive gear 67, and the second drive gear 67 is meshed on the tooth groove between the two parallel second racks 66.

[0051] In this embodiment, the two shift forks 50 are distributed in parallel and are both vertically fixed to the bottom of the two second connecting seats 65, thereby forming two L-shaped structures. The top heights of the second connecting seats 65 are inconsistent, which facilitates the staggered installation of the two second racks 66. The two second racks 66 extend in opposite directions toward the other second connecting seat 65. The two third sliders 64 are fixed to the part below the installation position of the second rack 66, thereby forming an upper end driven and lower end guided structure. When the fork motor 62 is working, the second driving gear 67 drives the two second racks 66 to transmit linearly in opposite directions, thereby driving the two shift forks 50 to move in opposite directions, and finally realizing the spacing control of the shift forks 50. When the two shift forks 50 are closed and close, they can further push the packaging box from the box pushing channel 24 into the packaging film bag. Then the two shift forks 50 move away from each other and open, shaping the bag opening of the packaging film bag so that it maintains a linear flat structure, which is convenient for subsequent hot-melt sealing of the bag opening.

[0052] Preferably, Figure 5 , 6As shown, the vertical drive device 70 includes a vertically arranged base plate 71, a pair of fourth guide rails 72 which are parallel and vertically fixed on the same side of the base plate 71, a fourth slider 73 which slides on the two fourth guide rails 72, a vertical motor 74 and a linear third rack 75. One end of the fork plate 61 in the horizontal direction is fixed on the two fourth sliders 73. The third rack 75 is vertically fixed on the fork plate 61. The vertical motor 74 is fixed on one side of the base plate 71 and its output shaft is provided with a third driving gear 76 which meshes with the tooth grooves of the third rack 75. Therefore, when the vertical motor 74 is working, the third driving gear 76 drives the third rack 75 to move in the up and down direction, and then drives the fork plate 61 to realize the up and down movement through the movement of the third rack 75. The fourth guide rail 72 stably guides the movement of the third rack 75, so as to facilitate the stable up and down driving of the fork plate 61 and the two forks 50.

[0053] Preferably, Figure 5 , 6 As shown, the third horizontal driving device 80 includes a top plate 81 horizontally arranged and perpendicular to the belt surface 12, a pair of fifth guide rails 82 arranged parallel to the lower end surface of the top plate 81, a fifth slider 83 slidably arranged along the two fifth guide rails 82, a second driving belt 84 circulating along the length direction of the top plate 81, and a third driving motor 85 driving the second driving belt 84 to circulate, the fifth guide rail 82 is arranged in parallel along the length direction of the top plate 81, a connecting plate 711 extends horizontally from the top of the base plate 71, and the connecting plate 711 is slidably arranged in the length direction of the two fifth guide rails 82 through two fifth sliders 83, and one of the fifth sliders 83 is clamped and fixed on the second driving belt 84.

[0054] Specifically, Figure 6 As shown, a movable block 86 is provided on one side of the fifth slider 83, a clamping channel 87 is formed between the inner side of the movable block 86 and the fifth slider 83, a plurality of limit meshing grooves (not marked in the figure) are formed on one side of the fifth slider 83 of the clamping channel 87, and the second drive belt 84 is a synchronous toothed belt with a convex tooth portion (not marked in the figure) matched with the limit meshing groove, so that the second drive belt 84 is clamped by the movable block 86, so as to achieve the purpose of driving the fifth slider 83 to slide back and forth along the fifth guide rail 82 through the transmission of the second drive belt 84.

[0055] In this embodiment, the second driving belt 84 is arranged between the two fifth guide rails 82. In addition, an L-shaped third sensing plate 88 is fixed to the side of the connecting plate 711. The upper end of the third sensing plate 88 extends beyond the upper end surface of the top plate 81. Two third sensing elements 89 are arranged on the edge of the top plate 81 on one side of the third sensing plate 88. The third sensing element 89 is a photoelectric sensor, and the third sensing plate 88 is a metal sheet that can cooperate with the photoelectric sensor, so that the travel distance of the fork 50 to push the packaging box can be more accurately controlled.

[0056] In particular, if Figure 7 As shown, an L-shaped first sensing plate 68 is extended from one side of the fork plate 61, a first sensing member 681 is provided on the top of the base plate 71 located on the same side as the sensing plate, another L-shaped second sensing plate 69 is provided on the back of the second connecting seat 65, and a second sensing member 691 is provided on the back of the fork plate 61 and located at the initial position where the two forks 50 are closed. In this embodiment, the first sensing member 681 and the second sensing member 691 are both photoelectric sensors, and the first sensing plate 68 and the second sensing plate 69 are both metal sheets that can be sensed and cooperated with photoelectric sensors. Therefore, through the cooperation of the sensing member and the sensing plate, it is possible to conveniently detect whether the fork 50 and the fork plate 61 have moved into place.

[0057] The working process and beneficial effects of the utility model are as follows:

[0058] First, the packaging box is placed on the belt surface 12 at the entrance end of the conveyor belt mechanism 10, and is driven to the unloading position 14 along with the transmission of the belt surface 12. At this time, the packaging box is blocked by the stop rod 23, and its edge is in contact with the stop rod 23. Then, the second horizontal driving device 32 on the first box pushing mechanism 30 works, and the packaging box is pushed to the position of the box pushing channel 24 along the edge of the stop rod 23 through the horizontal movement of the push rod 31. At this time, another packaging film bag transfer mechanism is cooperated to move the packaging film bag to the position of the box pushing channel 24, so that the packaging box can be partially bagged, and then the push rod 31 reset, the two forks 50 are driven by the vertical drive device 70 and the third horizontal drive device 80 to move to one side of the packaging box, and the two forks 50 are in a closed state. If they continue to move forward, the packaging box can be completely pushed into the packaging film bag. Then the fork device 60 drives the two forks 50 away from each other, so that the opening position of the packaging film bag is flattened, so that it forms a linear flat structure, which is convenient for the subsequent hot-melt sealing of the bag opening. Finally, the two forks 50 horizontally withdraw from the packaging film bag along the opening direction of the bag opening and reset again, completing the box pushing process of the packaging box. In this process, according to the size of the packaging box, the spacing of the two adjustment seats 21 is adjusted in advance by the first horizontal drive device 22, so that the spacing of the box pushing channel 24 is just adapted to the width of the packaging box, thereby realizing the adaptation process of the packaging box.

[0059] The utility model realizes automatic adaptation to packaging boxes of different sizes by introducing an adjustable unloading stop mechanism 20 and a multi-stage drive device, significantly improving the flexibility and versatility of the laminating machine, and can meet the diverse packaging needs on the market without the need for frequent replacement or adjustment of equipment, thereby reducing production conversion costs.

[0060] In addition, the fine design of the first box pushing mechanism 30 and the second box pushing mechanism 40, especially the position detection device on the second guide rail 321 and the toggle block 33 at the end of the push rod 31, ensures the precise control and stable transmission of the packaging box during the pushing process, improves the packaging quality, and reduces packaging defects caused by inaccurate positioning.

[0061] In particular, through modular design, such as the integration of the bifurcated device 60 and the vertical drive device 70, the device not only achieves efficient execution of complex actions, but also maintains the compactness of the overall structure, which is convenient for maintenance and adjustment.

[0062] The adjustable design enables quick adjustment to different packaging box sizes, while the clear modular structure simplifies daily maintenance and troubleshooting, reducing long-term operating costs.

[0063] In summary, the improved laminating machine box pushing device of the utility model can automatically adapt to the box pushing process of packaging boxes of different sizes by setting the spacing of the adjustment seat 21 to control the size of the box pushing channel 24, thereby effectively solving the limitations of traditional laminating machines in adapting to packaging boxes of different sizes, and in conjunction with the first box pushing mechanism 30 and the second box pushing mechanism 40, it can stably push the packaging box into the packaging film bag, fully improving the accuracy, flexibility and packaging quality of box pushing.

[0064] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
