[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up an automatic packaging component and a transmission component, places a bag containing the object to be weighed on a weighing platform. After weighing, the bag opening is placed in a packaging slot. An infrared sensor detects the bag and, through the control system on the weighing device itself, the electric push rod piston rod extends, causing the rack to slide in the movable slot. This causes the rack to mesh with the drive gear, rotating the drive gear through shaft A in gear slot A. The drive gear then meshes with the incomplete gear, causing the incomplete gear to rotate through the rotating shaft A. Shaft B rotates within gear groove B, causing the rotating plate to rotate closer to the fixed plate until sealing block A and sealing block B symmetrically contact the heavy bags and seal them. Then, the control system on the weighing device body controls the electric push rod, causing the piston rod of the electric push rod to shorten, thus rotating the rotating plate back to its original position. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. The rotating plate can not only restrict the opening of the heavy bags symmetrically within the packaging groove, but also automatically realize the packaging of the symmetrical heavy bags, resulting in high packaging efficiency.

[0015] 2. By setting up an extension component, when the rotating plate rotates into the receiving groove and contacts the inner wall of the receiving groove, the rack disengages from the drive gear, causing the extension block to contact the drive gear teeth. Since the rotating plate contacts the inner wall of the receiving groove, it acts as a limit, allowing the extension block to drive the movable block to slide on the connecting rod, causing the spring to stretch under force until the sealing block A and sealing block B are symmetrically sealed. This allows the present invention to seal and package weighing bags of different thicknesses and sizes, thereby improving the practicality of the present invention. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a weighing device with an automatic packaging structure, including a weighing device body 1, an automatic packaging component 2, and a transmission component 3; the weighing device body 1 includes a weighing platform 101, a support frame 102, and a display screen 103; the support frame 102 is fixedly connected to the weighing platform 101, and a recognition camera is provided on the support frame 102; the display screen 103 is fixedly connected to the support frame 102; a control system is provided on the weighing device body 1;

[0025] The automatic packaging assembly 2 is arranged on the support frame 102. The automatic packaging assembly 2 includes a fixed plate 201, a packaging slot 202, a movable slot 203, an electric push rod 204, a rotating plate 205, a receiving slot 206, a sealing block A 207, and a sealing block B 208. The fixed plate 201 is fixedly connected to the support frame 102. The packaging slot 202 is opened on the side of the fixed plate 201 near the support frame 102, and an infrared sensor is installed in the packaging slot 202. The movable slot 203 is opened in the packaging slot 202. The electric push rod 204 is fixedly connected in the movable slot 203. The rotating plate 205 is connected to the piston rod of the electric push rod 204 through the transmission assembly 3. The receiving slot 206 is opened in the movable slot 203. The sealing block A 207 is fixedly connected in the movable slot 203. The sealing block B 208 is arranged on the transmission assembly 3. The end of the rotating plate 205 does not contact the inner wall of the receiving slot 206 to facilitate the rotation of the rotating plate 205.

[0026] The transmission assembly 3 includes a gear groove A301, a gear groove B302, a rack 303, a drive gear 304, and an incomplete gear 305; the movable groove 203 has a gear groove A301; the gear groove A301 has a gear groove B302; the rack 303 is fixedly connected to the piston rod of the electric push rod 204 and is also fixedly connected to the sealing block B208; the drive gear 304 is rotatably disposed in the gear groove A301 via the rotating shaft A and meshes with the rack 303; the incomplete gear 305 is rotatably disposed in the gear groove B302 via the rotating shaft B and is fixedly connected to the rotating plate 205, and meshes with the drive gear 304.

[0027] This invention, through the setting of an automatic packaging component 2 and a transmission component 3, places a bag containing the object to be weighed on a weighing platform 101 for weighing. After weighing, the bag opening is placed in a packaging slot 202. An infrared sensor detects the bag, and the control system on the weighing device body 1 causes the piston rod of the electric push rod 204 to extend, causing the rack 303 to slide in the movable slot 203. This causes the rack 303 to mesh with the drive gear 304, causing the drive gear 304 to rotate through the rotating shaft A in the gear slot A301. This causes the drive gear 304 to mesh with the incomplete gear 305, causing the incomplete gear 305 to rotate. The rotating shaft B rotates within the gear groove B302, causing the rotating plate 205 to rotate closer to the fixed plate 201 until the sealing block A207 and sealing block B208 symmetrically contact the weighted bag and seal it. Then, the control system on the weighing device body 1 controls the electric push rod 204 to shorten its piston rod, causing the rotating plate 205 to rotate back to its original position. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. The rotating plate 205 can not only restrict the opening of the weighted bag symmetrically within the packaging groove 202, but also automatically realize the packaging of the weighted bag opening symmetrically, resulting in high packaging efficiency.

[0028] As a preferred embodiment, the device further includes an extension component 4; the extension component 4 is arranged on the rack 303; the extension component 4 includes a groove 401, a fixing block 402, a connecting rod 403, a movable block 404, a spring 405, and an extension block 406; the rack 303 has two grooves 401 symmetrically formed on the side away from the sealing block B208; the fixing block 402 is fixedly connected to the groove 401; the connecting rod 403 is fixedly connected to the fixing block 402; the movable block 404 is slidably sleeved on the two connecting rods 403; the spring 405 is sleeved on the connecting rod 406. The spring 405 is fixedly connected to the fixed block 402 and the movable block 404 at both ends on the rod 403; the extension block 406 is fixedly connected to the movable block 404 on the side near the drive gear 304, and the extension block 406 contacts the tooth block of the drive gear 304; the connecting rod 403 has a T-shaped structure, and the dimension of the connecting rod 403 on the side near the fixed block 402 is smaller than the dimension of the connecting rod 403 on the side away from the fixed block 402, so as to facilitate limiting the movement distance of the movable block 404; the height dimension of the movable block 404 is smaller than the height dimension of the rack 303.

[0029] This invention, by setting an extension component 4, allows the rotating plate 205 to rotate into the receiving groove 206 and contact the inner wall of the receiving groove 206. At this point, the rack 303 disengages from the drive gear 304, causing the extension block 406 to contact the teeth of the drive gear 304. Since the rotating plate 205's contact with the inner wall of the receiving groove 206 acts as a limiting force, the extension block 406 can drive the movable block 404 to slide on the connecting rod 403, causing the spring 405 to stretch under force until the sealing blocks A207 and B208 symmetrically seal the weighted bag. This allows the invention to seal and package weighted bags of different thicknesses and sizes, thus improving its practicality.

[0030] Working Principle: In use, firstly, the bag containing the object to be weighed is placed on the weighing platform 101 for weighing. After weighing, the bag opening is placed in the packaging slot 202. The infrared sensor detects the bag and, through the control system on the weighing device body 1, the piston rod of the electric push rod 204 extends, causing the rack 303 to slide in the movable slot 203. This causes the rack 303 to mesh with the drive gear 304, rotating the drive gear 304 through the rotating shaft A in the gear slot A301. The drive gear 304 then meshes with the incomplete gear 305, causing the incomplete gear 305 to rotate through the rotating shaft B in the gear slot B302. This causes the rotating plate 205 to rotate towards the fixed plate 201 until the rotating plate 205 rotates into the receiving slot 206 and contacts the inner wall of the receiving slot 206. At this point, the rack 303 disengages from the drive gear. The meshing of gear 304 causes the extension block 406 to contact the toothed block of the drive gear 304. Since the rotating plate 205 contacts the inner wall of the receiving groove 206, it acts as a limit, allowing the extension block 406 to drive the movable block 404 to slide on the connecting rod 403. This causes the spring 405 to stretch until the sealing block A207 and sealing block B208 contact the symmetrical weight bag and seal it. Then, the control system on the weighing device body 1 controls the electric push rod 204 to shorten the piston rod of the electric push rod 204. Under the elastic force of the spring 405, the extension block 406 will always be in contact with the toothed block of the drive gear 304, causing the extension block 406 to drive the movable block 404 to slide in the opposite direction on the connecting rod 403 until the rack 303 meshes with the drive gear 304 and rotates. At this time, the rotating plate 205 rotates in the opposite direction until it returns to its original position.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
