Description

Technical Field

[0001] This utility model relates to the field of integrated weighing and packaging technology, and in particular to a packaging device that is accurate in weighing and highly efficient. Background Technology

[0002] In modern industrial production, integrated weighing and packaging platforms have emerged to improve efficiency and reduce costs. Traditional material weighing and packaging processes are independent, and manual operation is cumbersome, error-prone, and inefficient. Integrated weighing and packaging platforms combine weighing and packaging functions to realize automated and continuous operation from weighing to packaging, which greatly improves production efficiency and reduces labor costs. However, in actual production, there are still some special bottles and cans, such as those with irregular shapes or special materials. The characteristics of these materials make it difficult for automated weighing and packaging to be completed accurately, and manual intervention is still required to ensure the accuracy of material weighing and the quality of packaging.

[0003] In the existing technology, automatic weighing packaging machines use pressure scales to weigh materials and use a sewing mechanism to make weighing and sewing work simultaneously. However, if the weight of the material to be packaged is insufficient, additional material needs to be added. Current automatic weighing packaging machines do not have the corresponding equipment. In addition, the size of the packaging boxes is not uniform, and current automatic weighing packaging machines fail to fix the packaging boxes of different sizes to prevent them from shaking during feeding. Furthermore, there is also the problem that the tape is usually placed in various places during the packaging process, making it difficult to find the tape when needed.

[0004] To address the aforementioned issues, an existing patent (publication number: CN221624191U) proposes a packing device that offers accurate weighing and high efficiency. This device features a weighing sensor mounted on the top of an automatic weighing base plate, with a pressure sensor positioned on the side of the weighing sensor. A fixing plate is fixedly connected to the top of the pressure sensor, and a packing box weighing and fixing assembly is mounted on the top of the fixing plate. This invention, by incorporating the packing box weighing and fixing assembly, facilitates the fixing of packing boxes according to their different sizes. The length of the packing box can be adjusted by changing the position of the bolts in the adjustment holes, thereby changing the placement space of the packing box. Additionally, a positioning component facilitates the installation of tape on the device, preventing the tape from being scattered and difficult to find when needed. Furthermore, a device for holding a cutting blade is included, allowing for the cutting of the tape after packing, making it convenient and practical.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when packaging particulate matter such as nuts and candies, special packaging bottles, such as five-pointed stars, may be used due to commercial factors, requiring manual intervention for packaging. However, manual packaging involves separate processes for ingredient preparation, weighing, and packaging, resulting in slow speed and low efficiency. Furthermore, when filling the packaging bottles, even with a fast equipment response, the high material discharge rate can lead to overflow and waste after sufficient material is added.

[0006] Therefore, a packing device that is accurate in weighing and highly efficient is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a packaging device that is accurate in weighing and highly efficient, which can solve the problems of slow manual speed, low efficiency, and easy overflow and waste during filling when packaging special bottles of particulate matter.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a packaging device with accurate and efficient weighing, comprising an integrated weighing and packaging platform, wherein a pressure scale is movably connected to the front side of the top of the integrated weighing and packaging platform, a self-service material replenishment mechanism is movably connected to the top of the integrated weighing and packaging platform, and an aperture adjustment mechanism is movably connected to the inner side of the self-service material replenishment mechanism.

[0009] The self-service replenishment mechanism includes a support base, an electric telescopic support column, a support beam, a storage tank, and a quick-adaptive positioning component. The support base is fixedly connected to the rear side of the top of the weighing and packaging integrated platform. The electric telescopic support column is fixedly connected to the top of the support base. The support beam is fixedly connected to the top of the electric telescopic support column. The storage tank is movably connected to the front side of the support beam. The quick-adaptive positioning component is movably connected to the top of the pressure scale.

[0010] Preferably, the aperture adjustment mechanism includes an electric rotating shaft, a support block, an electric stirring roller, a shielding disc, and a discharge hole.

[0011] Preferably, the electric rotating shaft is movably connected to the top of the inner side of the storage tank, the top cover disc is fixedly connected to the bottom of the electric rotating shaft, the top cover disc is movably connected to the inner side of the storage tank, the bottom cover disc is fixedly connected to the inner side of the storage tank, and the bottom cover disc is disposed at the bottom of the top cover disc.

[0012] Preferably, the support block is fixedly connected to the outside of the electric rotating shaft, the electric stirring roller is movably connected to the outside of the support block, and the electric stirring roller and the support block are arranged on the top of the top cover disc.

[0013] Preferably, the quick-adaptive positioning assembly includes a carrier box, an electric arc-shaped guide plate, a sliding block, a connecting rod, a positioning rod, and an elastic clamping pad.

[0014] Preferably, the carrier box is fixedly connected to the top of the pressure scale, the electric arc-shaped guide plate is movably connected to the bottom of the inner side of the carrier box, the sliding block is movably connected to the inner side of the electric arc-shaped guide plate, the linkage rod is fixedly connected to the top of the sliding block, the linkage rod is slidably connected to the top of the carrier box, the positioning rod is fixedly connected to the top of the linkage rod, the positioning rod is set on the top of the carrier box, and the elastic clamping pad is movably connected to the outer side of the positioning rod.

[0016] Preferably, a conveying pipe is movably connected to the bottom of the storage tank, and the conveying pipe is located at the bottom of the sensing valve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a self-service material replenishment mechanism, can realize the integration of material preparation, weighing, and packaging, which greatly saves the overall workflow and time. Through the coordinated operation of storage tanks, electric arc guide plates, electric telescopic support columns, and other devices, it can automatically adapt to packaging bottles of different shapes, such as special five-pointed star shaped bottles. During packaging, the operator only needs to adjust the material preparation parameters in advance and place the bottles. The equipment can automatically complete the positioning, material conveying, weighing, and other operations without the need for manual intervention in each step. This effectively solves the problem of slow speed and low efficiency caused by the separate operation of each step in the previous manual packaging, and significantly improves packaging efficiency.

[0019] 2. This application effectively avoids material overflow and waste by setting an orifice adjustment mechanism, while also preventing material blockage. The fit between the top and bottom shielding discs' discharge holes is controlled by an electric rotating shaft. Initially, the holes are completely shielded to prevent material from falling. During replenishment, the flow rate can be adjusted to full discharge. As replenishment is nearing completion, the orifice diameter can be gradually reduced to precisely control the discharge volume. Furthermore, the electric rotating shaft drives an electric stirring roller to agitate the material, preventing material accumulation and blockage. This design effectively solves the problem of overflow and waste caused by high discharge flow rate when filling baled bottles. It improves material utilization efficiency and reduces production costs while ensuring efficient replenishment. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A packing device with accurate and efficient weighing includes a weighing and packing integrated platform 1, a pressure scale 2 is movably connected to the front side of the top of the weighing and packing integrated platform 1, a self-service feeding mechanism 3 is movably connected to the top of the weighing and packing integrated platform 1, and an aperture adjustment mechanism 4 is movably connected to the inner side of the self-service feeding mechanism 3.

[0029] The self-service replenishment mechanism 3 includes a support base 31, an electric telescopic support column 32, a support beam 33, a storage tank 34, and a quick-adaptive positioning component 35. The support base 31 is fixedly connected to the rear side of the top of the weighing and packaging integrated platform 1. The electric telescopic support column 32 is fixedly connected to the top of the support base 31. The support beam 33 is fixedly connected to the top of the electric telescopic support column 32. The storage tank 34 is movably connected to the front side of the support beam 33. The quick-adaptive positioning component 35 is movably connected to the top of the pressure scale 2.

[0030] In this embodiment: the storage tank 34 can be supported by the support base 31 and the support beam 33 to ensure that it is located above the quick-adaptive positioning component 35, and the height of the support beam 33 can be adjusted by the electric telescopic support column 32 to adapt to the height of different packaging bottles, thereby cooperating with the sensor at the bottom of the pressure scale 2 for automatic material replenishment.

[0031] Specifically, such as Figure 5 As shown, the aperture adjustment mechanism 4 includes an electric rotating shaft 41, a support block 42, an electric stirring roller 43, a shielding disc 44, and a discharge hole 45.

[0032] Specifically, such as Figure 5 As shown, the electric rotating shaft 41 is movably connected to the top of the inner side of the storage tank 34, the top cover disc 44 is fixedly connected to the bottom of the electric rotating shaft 41, the top cover disc 44 is movably connected to the inner side of the storage tank 34, the bottom cover disc 44 is fixedly connected to the inner side of the storage tank 34, and the bottom cover disc 44 is disposed at the bottom of the top cover disc 44.

[0033] Specifically, such as Figure 5 As shown, the support block 42 is fixedly connected to the outside of the electric rotating shaft 41, and the electric stirring roller 43 is movably connected to the outside of the support block 42. The electric stirring roller 43 and the support block 42 are set on the top of the top cover disk 44.

[0034] In this embodiment: During the feeding process, the sensor controls the electric rotating shaft 41 to adjust the discharge flow rate. Initially, the top cover disc 44 completely covers the bottom cover disc 44, and the material cannot fall to the bottom of the storage tank 34 through the discharge port. The sensing valve 5 also cannot feed. During feeding, the electric rotating shaft 41 rotates the top cover disc 44 so that its discharge hole 45 is in contact with the discharge hole 45 of the bottom cover disc 44, achieving the maximum discharge flow rate. The drive motor of the electric rotating shaft 41 is located in the non-feeding area at the top of the storage tank 34. When the pressure scale 2 sensor is about to complete feeding, the electric rotating shaft 41 gradually rotates the top cover disc 44 to reduce the diameter of the discharge hole 45 and avoid excessive discharge and overflow.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the quick-adaptive positioning assembly 35 includes a carrier box 35a, an electric arc-shaped guide plate 35b, a sliding block 35c, a connecting rod 35d, a positioning rod 35e, and an elastic clamping pad 35f.

[0036] Specifically, such as Figure 3 , Figure 4As shown, the carrier box 35a is fixedly connected to the top of the pressure scale 2, the electric arc guide plate 35b is movably connected to the bottom of the inner side of the carrier box 35a, the sliding block 35c is movably connected to the inner side of the electric arc guide plate 35b, the linkage rod 35d is fixedly connected to the top of the sliding block 35c, the linkage rod 35d is slidably connected to the top of the carrier box 35a, the positioning rod 35e is fixedly connected to the top of the linkage rod 35d, the positioning rod 35e is set on the top of the carrier box 35a, and the elastic clamping pad 35f is movably connected to the outer side of the positioning rod 35e.

[0037] In this embodiment: by activating the electric arc guide plate 35b and the electric telescopic support column 32, the packaged bottle is positioned and the height of the conveying pipe 6 is adjusted. The drive motor of the electric arc guide plate 35b is installed at the bottom of the carrier box 35a. When it rotates, it will drive the inner sliding block 35c to slide along the inner arc groove. The connecting rod 35d moves inward accordingly, pulling the positioning rods 35e in four directions to move inward at the same time. During the movement, the elastic clamping pad 35f on the outside of the positioning rod 35e first contacts the packaged bottle to adapt to its shape, such as special shapes like commercial sugar jars, and then slowly pushes it to prevent the packaged bottle from tipping over. When the packaged bottle is positioned at the center of the carrier box 35a, the conveying pipe 6 is exactly above the packaged bottle.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, a sensing valve 5 is movably connected to the bottom of the inner side of the storage tank 34.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a conveying pipe 6 is movably connected to the bottom of the storage tank 34, and the conveying pipe 6 is located at the bottom of the sensing valve 5.

[0040] In this embodiment: the closing state of the storage tank 34 can be controlled by the sensing valve 5 to avoid material leakage caused by misalignment of the shielding disc 44, and the material replenishment can be guided by the conveying pipe 6.

[0041] Working Principle: When bottling granular materials, such as nuts and gummy candies, the corresponding granules are first filled into the storage tank 34 through the inlet at the top. Then, the operator adjusts the mixing parameters according to the bottle size and places the bottle near the center of the top of the carrier box 35a. Simultaneously, the electric arc-shaped guide plate 35b and the electric telescopic support column 32 are activated to position the bottle and adjust the height of the conveying pipe 6. The drive motor of the electric arc-shaped guide plate 35b is located at the bottom of the carrier box 35a. When the electric arc-shaped guide plate 35b rotates, it drives... The sliding block 35c on its inner side slides along its inner arc groove, and in conjunction with it, causes the connecting rod 35d to move inward simultaneously, thereby pulling the positioning rods 35e in all four directions to move inward simultaneously. During the movement, the elastic clamping pads 35f on the outer side of the positioning rods 35e will preferentially contact the packaging bottle and adapt to its outer shape, such as the unique shape of some commercial sugar containers, and simultaneously align and slowly push inward to prevent tipping. Finally, after the packaging bottle is positioned at the center of the carrier box 35a, the conveying pipe 6 is just above the packaging bottle. According to the parameters set in advance on the right-side operating platform, when the overall weight of the pressure scale 2 does not reach the required height of the packaging bottle, the bottom of the pressure scale 2... The sensor in the storage tank 34 will respond to the sensing valve 5 inside the storage tank to quickly discharge material, and close it quickly after the weight is appropriate. After the replenishment is completed, the personnel will restore the equipment, remove the packaging bottles for capping and collection, and proceed to the next round of packaging. This integrates batching, weighing, and packaging, saving the overall workflow and time. Secondly, during the replenishment process, the sensor can control the electric rotating shaft 41 to adjust the discharge flow rate. In the initial state, the top shielding disc 44 completely covers the bottom shielding disc 44, preventing material from falling through the discharge port to the bottom of the storage tank 34 and being replenished through the sensing valve 5. When replenishing, the sensor will control the electric rotating shaft 41 to adjust the discharge flow rate. The electric rotating shaft 41 rotates the top cover disk 44 so that it fits into the discharge hole 45 of the bottom cover disk 44 to achieve a complete discharge flow rate. The drive motor of the electric rotating shaft 41 is located in the non-feeding part at the top of the storage tank 34. When the pressure scale 2 sensor is about to complete the replenishment, the top cover disk 44 is gradually rotated to reduce the diameter of the discharge hole 45 to avoid excessive discharge and overflow. While the electric rotating shaft 41 is rotating, the electric stirring roller 43 supported by its outer support block 42 agitates the material. The drive motor of the electric stirring roller 43 is located inside the support block 42 to prevent them from squeezing and accumulating against each other, forming stress, making it difficult to discharge and causing blockage.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
