[0031] As attached Figures 1-7 As shown, this utility model includes: a frame 1, with a plurality of conveying rollers 101 disposed inside the frame 1, and a conveying mechanism body 2 disposed on the frame 1. The conveying mechanism body 2 includes two support plates 201, both of which are disposed above the plurality of conveying rollers 101. Conveying components are disposed on both support plates 201. Adjusting components are disposed between the bottom of the two conveying mechanism bodies 2 and the frame 1. The adjusting components include two bidirectional lead screws 209 disposed inside the frame 1, and the outer surfaces of the two bidirectional lead screws 209 are threaded with two The top of each of the four sliders 208 is fixedly connected to a connecting post 207. The top of each of the four connecting posts 207 is fixedly connected to the bottom of the two support plates 201. One end of one of the bidirectional lead screws 209 is provided with a first handwheel 212, and the outer surfaces of the two bidirectional lead screws 209 are provided with first synchronous pulleys 210. A first synchronous belt 211 is connected between the two first synchronous pulleys 210. The first synchronous belt 211 and the first synchronous pulley 210 cooperate with each other to enable the two bidirectional lead screws 209 to rotate synchronously.

[0032] A visual inspection camera 5 is installed on one side of the top of the rack 1, and the height of the visual inspection camera 5 is higher than the protective cover 202. The position of the packaging box can be confirmed by the visual inspection camera 5 working in conjunction with the existing visual inspection.

[0033] Furthermore, such as Figures 1-4 As shown, the bidirectional lead screw 209 is located at the bottom of the support plate 201, and the connecting column 207 passes through the gap between the two conveying rollers 101. The connecting column 207 can connect the slider 208 to the support plate 201, so that when the slider 208 moves, it can drive the support plate 201 to move, thereby adjusting the distance between the two support plates 201.

[0034] During adjustment, the first handwheel 212 is rotated, and the first synchronous wheel 210 and the first synchronous belt 211 work together to drive the two bidirectional lead screws 209 to rotate synchronously. When each bidirectional lead screw 209 rotates, it drives the two sliders 208 on it to move closer or further away from each other, thereby driving the two support plates 201 to move closer or further away from each other, so as to realize the adjustment of the distance between the two support plates 201 to meet the needs of different sized packaging boxes.

[0035] Furthermore, such as Figure 3 and Figure 4 As shown, the conveying component includes a protective cover 202 installed on the top of the support plate 201. A first motor 203 is provided at the bottom of the support plate 201 and located below the conveying roller 101. Both the output shaft of the first motor 203 and the top of the support plate 201 are provided with drive wheels 204. A drive belt 205 located inside the protective cover 202 is connected between the two drive wheels 204. The first motor 203 can drive the drive belt 205 to rotate through the drive wheels 204. After the two sides of the packaging box are respectively attached to the two drive belts 205, the packaging box can move on the top of the conveying roller 101 under the drive of the drive belts 205.

[0036] The top of the support plate 201 is provided with several support rollers 206, which are all located inside the drive belt 205. The support rollers 206 can support and limit the drive belt 205 to improve the stability of the drive belt 205 during use.

[0037] Furthermore, such as Figures 1-2 As shown, a lifting mechanism 3 is provided on the frame 1. The lifting mechanism 3 includes two uprights 301 that are fixedly installed on both sides of the frame 1. Each of the two uprights 301 has a lifting screw installed in it through a bearing. Each of the two uprights 301 has a sliding groove on the side that is close to each other. A lifting beam 305 is slidably connected between the two sliding grooves. The lifting beam 305 is threaded between the two lifting screws. A second handwheel 304 is provided at the top of each of the two lifting screws. The second handwheel 304 facilitates the rotation of the lifting screw. During the rotation of the lifting screw, the lifting beam 305 can be raised and lowered. Adjusting the height of the lifting beam 305 can further adjust the height of the film sealing mechanism 4.

[0038] The bottom ends of the two lifting screws are connected to the second synchronous pulleys 302, and the two second synchronous pulleys 302 are connected to the second synchronous belt 303. The cooperation between the second synchronous belt 303 and the second handwheel 304 enables the two lifting screws to rotate synchronously.

[0039] Furthermore, such as Figure 1 , Figures 5-7As shown, a film sealing mechanism 4 is provided on the lifting beam 305. The film sealing mechanism 4 includes a support frame 401 provided on the lifting beam 305. A second connecting plate 419 is installed inside the support frame 401. A cylinder 402 is installed on the top of the second connecting plate 419. The piston rod of the cylinder 402 passes through the second connecting plate 419 and is fixedly connected to a first connecting plate 403. A hot press head 404 is provided at the bottom of the first connecting plate 403. A film cutting knife is provided on the outer periphery of the bottom of the hot press head 404. The support frame 401 and the second connecting plate 419 cooperate with each other to support the cylinder 402. The cylinder 402 can drive the hot press head 404 to rise and fall through the first connecting plate 403. The hot press head 404 can heat seal the packaging film onto the packaging box to achieve packaging. When the lifting beam 305 rises and falls, it can drive the support frame 401 to rise and fall.

[0040] Furthermore, such as Figure 6 As shown, a number of mounting bolts 406 are provided between the top of the hot press head 404 and the first connecting plate 403. A spring 407 is sleeved on the outer surface of the mounting bolts 406 and located between the first connecting plate 403 and the hot press head 404. The mounting bolts 406 are interlocked with the first connecting plate 403 and threaded with the hot press head 404. The hot press head 404 can be replaced after the mounting bolts 406 are unscrewed. The force of the spring 407 can buffer the hot press head 404 when it descends to seal the packaging box, reducing the impact on the packaging box.

[0041] Furthermore, such as Figure 6 As shown, a hot press head 404 is fixedly installed on the top of the first connecting plate 403. The top of the hot press head 404 passes through the second connecting plate 419 and extends above the second connecting plate 419. The hot press head 404 can limit the first connecting plate 403 to improve the stability of the first connecting plate 403 when it is raised or lowered.

[0042] Furthermore, such as Figure 5 As shown, two support seats 409 are fixedly installed on the top of the support frame 401. Each support seat 409 has a groove 410 on its top. A second threaded rod 418 is inserted between the two grooves 410. Two clamps 411 are threadedly connected to the outer surface of the second threaded rod 418. The support seat 409 and the second threaded rod 418 cooperate to support the membrane roll. Pulling the second threaded rod 418 upward separates it from the groove 410. After unscrewing one of the clamps 411, the second threaded rod 418 is inserted into the center of the membrane roll. Then, the two clamps 411 are tightened to limit the membrane roll. Finally, the clamps 411 are put back between the two grooves 410 to complete the installation of the membrane roll.

[0043] Furthermore, such as Figure 5As shown, a second motor 412 is installed on the top of the support frame 401. The output shaft of the second motor 412 is connected to a first screw 413. A fixed plate 414 is fixedly sleeved on the outer surface of the first screw 413, and a movable plate 415 is threadedly connected to the outer surface of the first screw 413. After winding and sealing, the roll of waste film material is fixed between the first screw 413, the fixed plate 414 and the movable plate 415, and is driven by the second motor 412 to wind up the waste film material. Specifically, after unscrewing the movable plate 415, the roll of waste film material is sleeved on the outer surface of the first screw 413, and then the movable plate 415 is tightened so that the movable plate 415 and the fixed plate 414 clamp the roll.

[0044] Furthermore, such as Figures 5-7 As shown, the support frame 401 is provided with two rollers 417. The two rollers 417 are located below the first screw 413 and the second threaded rod 418, respectively, and are located on both sides of the hot press head 404. The rollers 417 can support and guide the film material so that the film material can be placed stably on the packaging box.

[0045] In use, turn the first handwheel 212 to adjust the distance between the two drive belts 205, turn the second handwheel 304 to drive the lifting screw to rotate and drive the lifting beam 305 to rise and fall. After adjusting the height of the film sealing mechanism 4, the packaging box containing the material is conveyed by the drive belt 205 on the top of the conveyor roller 101, and the position of the packaging box is detected by the visual inspection camera 5. When the packaging box reaches directly below the hot press head 404, the cylinder 402 pushes the first connecting plate 403 to descend, so as to drive the hot press head 404 and the film cutter to descend, so that the hot press head 404 and the film cutter cooperate to cut the film material and heat seal it on the packaging box to complete the packaging.
