Description

Technical Field

[0001] This application relates to the field of packaging weighing, specifically a packaging weighing device. Background Technology

[0002] Drugs play a very important role in medicine. They can be used to treat diseases. Their main active ingredients are active pharmaceutical ingredients (APIs). After the APIs are produced, they need to be quantitatively packaged into barrels and bags for storage and awaiting shipment. To ensure accurate packaging weight, packaging weighing devices are usually used to quantitatively package various materials.

[0003] An automatic packaging weighing device is proposed in utility model patent CN219097038U, including a fixed frame and a base frame. A material box for loading materials is fixed to the top of the fixed frame with screws. A pipe for conveying materials into the material box is inserted into the bottom of the outer side of the material box. A connecting frame for fixing a threaded rod is screwed to the outer side of the fixed frame. Support sleeve A and support sleeve B are threaded to the outer side of the threaded rod, with support sleeve A located to the left of support sleeve B. Support block A for fixing connecting plate A is welded to the outer side of support sleeve A. Support block B for fixing connecting plate B is welded to the outer side of support sleeve B. A weighing device for weighing is fixed to one side of the base frame with screws. This device solves the problem that existing automatic packaging weighing devices are inconvenient for fixing the filling bags and unfolding the filling bags, which cannot improve the filling efficiency and affects the use.

[0004] The device is equipped with a fixed frame, and a connecting frame is connected to the outside of the fixed frame. When packaging and weighing, the staff needs to pull the horizontal plates on the connecting plates A and B, and then open the two sides of the filling bag and place it on the connecting plates A and B. The filling bag is fixed by springs and pressure plates. However, the staff needs to manually load and unload the filling bag before and after packaging, which is cumbersome and the packaging efficiency is low. Utility Model Content

[0005] To address the problem of low packaging efficiency in existing technologies, this utility model provides a packaging weighing device.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a packaging weighing device, including a base, a fixed frame fixedly mounted on the base, a storage tank fixedly mounted on the top of the fixed frame, a discharge pipe mounted on one side of the storage tank, an mounting frame slidably mounted on the side of the fixed frame near the discharge pipe, a sliding groove provided in the mounting frame, two sets of connecting rods slidably mounted in the sliding groove, one end of the connecting rod located outside the mounting frame and fixedly mounted with a fixed rod, a vertical plate fixedly mounted at the bottom of the fixed rod, a clamping plate rotatably mounted on the side of the fixed rod, a motor fixedly mounted on one side of the fixed rod, the output shaft of the motor being drivenly connected to one end of the clamping plate, and a weighing platform mounted on the base below the discharge pipe;

[0008] It also includes a drive mechanism, which is mounted on the fixed frame;

[0009] It also includes an adjustment mechanism, which is mounted on the mounting bracket.

[0010] Preferably, the driving mechanism includes a second motor, a first screw, and a slider. The second motor is fixedly mounted on the bottom of the fixed frame, the first screw is rotatably connected to the fixed frame, and the output shaft of the second motor is fixedly connected to one end of the first screw. The fixed frame has a through hole, and the slider is fitted onto the first screw. One end of the slider passes through the through hole and is fixedly connected to the mounting frame. When the operator starts the second motor, the second motor drives the first screw to rotate. When the first screw rotates, it drives the slider and the mounting frame to move vertically. The through hole limits the movement of the slider to ensure the stability of the slider's sliding.

[0011] Preferably, the adjusting mechanism includes a third motor and a second screw. The third motor is fixedly mounted on the side of the mounting bracket. The second screw is located in the first slide groove and is rotatably connected to the mounting bracket. The two ends of the second screw have threaded sections in opposite directions. Two sets of connecting rods are each sleeved on one side of the second screw. The output shaft of the third motor is fixedly connected to one end of the second screw. When the operator starts the third motor, the third motor drives the second screw to rotate, which in turn causes the second screw to drive the two sets of connecting rods to move closer or further apart through the opposite threaded sections on both sides. During the sliding process of the two sets of connecting rods, the first slide groove limits their movement to ensure the stability of the sliding and facilitates operation.

[0012] Preferably, the two sets of vertical plates are both set with an arc surface on the opposite side, and the clamping plate is provided with a groove that matches the arc surface. By setting the arc-shaped vertical plates and the clamping plate with the groove, the bag can be better clamped and fixed, ensuring the stability of the clamping.

[0013] Preferably, a sleeve is slidably fitted at the bottom of the discharge pipe, and an insert rod is fixedly installed on the outer wall of the sleeve. One end of the insert rod is fixedly connected to the mounting frame. When the mounting frame drives the vertical plate to rise and fall, the sleeve slides synchronously along the discharge pipe. The discharge height of the discharge pipe is adjusted by the sleeve to ensure the accuracy of the discharge.

[0014] Preferably, the fixed frame is provided with a second sliding groove, and the mounting frame is fixedly provided with a locking block that matches the second sliding groove. By setting the second sliding groove and the locking block, the mounting frame is further limited, ensuring the stability of the mounting frame during the sliding process.

[0015] Preferably, a control terminal is fixedly installed on the weighing platform, wherein control components such as motor one, motor two, and motor three are all electrically connected to the control terminal, which facilitates convenient operation of each component by the staff.

[0016] The advantages of adopting the above technical solution are:

[0017] This utility model includes a base with a fixed frame on it. A storage tank is fixedly mounted on the top of the fixed frame, and a discharge pipe is located on one side of the storage tank. A mounting frame is slidably mounted on the side of the fixed frame near the discharge pipe.

Detailed Implementation

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

[0024] like Figure 1-3 As shown in the figure, this utility model embodiment discloses a packaging weighing device, including a base 1, a drive mechanism, and an adjustment mechanism. A fixed frame 2 is fixedly installed on the base 1, and a storage tank 3 is fixedly installed on the top of the fixed frame 2. A discharge pipe 301 is provided on one side of the storage tank 3. An installation frame 4 is slidably installed on the side of the fixed frame 2 near the discharge pipe 301. A sliding groove 401 is provided in the installation frame 4. Two sets of connecting rods 5 are slidably arranged in the sliding groove 401 at intervals. One end of the connecting rod 5 is located outside the installation frame 4 and a fixed rod 6 is fixedly installed. A vertical plate 601 is fixedly installed at the bottom of the fixed rod 6. A clamping plate 602 is rotatably installed on the side of the fixed rod 6. A motor 7 is fixedly installed on one side of the fixed rod 6. The output shaft of the motor 7 is connected to one end of the clamping plate 602. A weighing platform 8 is provided on the base 1 below the discharge pipe 301. The drive mechanism is installed on the fixed frame 2, and the adjustment mechanism is installed on the installation frame 4.

[0025] In at least one embodiment, the driving mechanism includes a second motor 9, a first screw 901, and a slider 902. The second motor 9 is fixedly mounted on the bottom of the fixed frame 2. The first screw 901 is rotatably connected to the fixed frame 2. The output shaft of the second motor 9 is fixedly connected to one end of the first screw 901. The fixed frame 2 is provided with a through hole 201. The slider 902 is fitted onto the first screw 901. One end of the slider 902 passes through the through hole 201 and is fixedly connected to the mounting frame 4. When the operator starts the second motor 9, the second motor 9 drives the first screw 901 to rotate. When the first screw 901 rotates, it drives the slider 902 and the mounting frame 4 to move vertically. The through hole 201 limits the movement of the slider 902 to ensure the stability of the slider 902's sliding.

[0026] In at least one embodiment, the adjusting mechanism includes a third motor 402 and a second screw 403. The third motor 402 is fixedly mounted on the side of the mounting bracket 4. The second screw 403 is located in the first slide groove 401 and is rotatably connected to the mounting bracket 4. The two ends of the second screw 403 are provided with threaded sections in opposite directions. Two sets of connecting rods 5 are each sleeved on one side of the second screw 403. The output shaft of the third motor 402 is fixedly connected to one end of the second screw 403. When the operator starts the third motor 402, the third motor 402 drives the second screw 403 to rotate, thereby causing the second screw 403 to drive the two sets of connecting rods 5 to move closer or further apart through the opposite threaded sections on both sides. During the sliding process of the two sets of connecting rods 5, the first slide groove 401 limits them to ensure the stability of the sliding and facilitates operation.

[0027] In at least one embodiment, the two sets of vertical plates 601 are both set as arc surfaces on opposite sides, and the clamping plate 602 is provided with a groove that matches the arc surface. By setting the arc-shaped vertical plates 601 and the clamping plate 602 with the groove, the filling bag can be better clamped and fixed, ensuring the stability of the clamping.

[0028] In at least one embodiment, a sleeve 302 is slidably fitted at the bottom of the discharge pipe 301, and an insert rod is fixedly installed on the outer wall of the sleeve 302. One end of the insert rod is fixedly connected to the mounting frame 4. When the mounting frame 4 drives the vertical plate 601 to rise and fall, the sleeve 302 slides synchronously along the discharge pipe 301. The discharge height of the discharge pipe 301 is adjusted by the sleeve 302 to ensure the accuracy of the discharge.

[0029] In at least one embodiment, the fixed frame 2 is provided with a second sliding groove 202, and the mounting frame 4 is fixedly provided with a locking block that matches the second sliding groove 202. By setting the second sliding groove 202 and the locking block, the mounting frame 4 is further limited, ensuring the stability of the mounting frame 4 during the sliding process.

[0030] In at least one embodiment, a control terminal is fixedly installed on the weighing platform 8, wherein control components such as motor 1 7, motor 2 9, and motor 3 402 are all electrically connected to the control terminal, which facilitates convenient operation of each component by the staff.

[0031] During packaging and weighing, the raw materials are placed in the storage tank 3 on the fixed frame 2. Then, the worker places the filling bag on the weighing platform 8 on the base 1 and opens it. The worker then controls the mounting frame 4 to slide vertically according to the bag's specifications via a drive mechanism. This causes the mounting frame 4 to move the vertical plate 601 to a height suitable for the filling bag, inserting the vertical plate 601 into the bag's opening. The worker then uses an adjustment mechanism to move two sets of connecting rods 5 within the slide groove 401, causing them to separate. This allows the connecting rods 5 to drive the vertical plate 601 to expand the bag's opening outwards. Once the bag opening is tightly fitted against the outside of the vertical plate 601, the worker starts the motor 7. Two sets of motors 7 drive two sets of clamping plates 602 to rotate along the fixed rod 6, ultimately causing the clamping plates 602 and the vertical plate 601 to clamp the opening of the filling bag, ensuring stability during subsequent packaging operations. A control valve is installed on the discharge pipe 301, which can then be activated by the operator to allow the storage tank 3 to fill the filling bag. The operator can monitor the weight of the filling in real time through the weighing platform 8. Once the appropriate weight is reached, the filling stops, and then the clamping plates 602 are rotated in the opposite direction by motor 7, causing the two sets of vertical plates 601 to move closer together, thus disengaging the clamping plates 602 and the vertical plate 601 from the bag opening. The filled bag can then be removed. The operation is convenient and improves packaging efficiency.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
