[0010] Preferably, a pair of rollers are connected to both inner side walls of the connecting table through bearing seats. The length of the rollers is less than the width of the connecting table. The installation heights between the pair of rollers installed on the same side of the connecting table are different.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) In this utility model, a weighing platform is mainly used to weigh capsules individually. A capsule accommodating plate is provided on the weighing platform, and a plurality of evenly distributed capsule accommodating holes are opened on the plate. The filled capsules are put into the capsule accommodating holes. A tray is provided on the lower surface of the capsule accommodating holes, and a pressure sensing patch is installed on the tray. When the capsule enters the capsule accommodating hole of the capsule accommodating plate, it is lifted by the tray, and the gravity of the capsule acts entirely on the pressure sensing patch, thereby realizing the weighing of a single capsule. When weighing the capsules through the above technical solution, since each pressure sensing patch exists independently, each capsule can be numbered.

In this way, each weighing platform can have enough time to stand still after the capsules are filled, so that the pressure sensing patch can provide a stable reading.

[0017] (3) In order to ensure that the capsules can be accurately put into the capsule accommodating holes of the capsule accommodating plate, a lead screw slide table and a connecting table are also provided in this utility model. Through the lead screw slide table and the connecting table, two-direction movement of the weighing platform can be realized. The weighing platform can move in two directions, so that different capsule accommodating holes on the capsule accommodating plate can be aligned with the output port of the filling machine, enabling the capsules to be accurately put into the capsule accommodating holes of the capsule accommodating plate and fall on the tray.

[0018] (4) Further, in order to facilitate the understanding of the working of the weighing platform, a conveying mechanism is also provided in this utility model. The conveying mechanism can be connected to the discharge port of the filling machine in the prior art, so as to intermittently convey the filled capsules to the weighing mechanism through the conveying mechanism. On the one hand, this can make the capsules be evenly put into the capsule accommodating holes of the capsule accommodating plate on the weighing platform, and on the other hand, the intermittent input can also provide a certain amount of time for the weighing and replacement of the weighing platform.

Specific embodiments

[0029] To make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0032] Figures 1-5This is the structural diagram of the filling and weighing device for the soft capsule filling machine in this embodiment. The weighing device in this embodiment includes a weighing mechanism 200, and the weighing mechanism 200 includes a plurality of weighing platforms 203. In this embodiment, the weighing platforms 203 in the weighing mechanism 200 can weigh the capsules. The specific structure is as follows: The weighing platform 203 includes a connecting plate 2031. Columns 2032 are provided at the four corners of the upper surface of the connecting plate 2031. A movable plate 2033 is slidably sleeved on the columns 2032. A plurality of trays 2034 are equidistantly distributed on the movable plate 2033. A capsule receiving plate 2035 is installed at the upper end of the column 2032, and a plurality of capsule receiving holes are evenly opened on the capsule receiving plate 2035. The capsule receiving holes coincide with the projections of the trays 2034. The capsules filled by the filling machine enter the capsule receiving holes of the capsule receiving plate 2035 and are lifted by the trays 2034, so that the capsules stay in the capsule receiving holes. A pressure sensing patch is provided on the upper surface of the tray 2034, and the gravity of the capsule acts entirely on the pressure sensing patch, thereby realizing the weighing of a single capsule. When weighing the capsules through the above technical solution, it is set that filling the capsule receiving holes of the capsule receiving plate 2035 with capsules is one stroke. Since each pressure sensing patch exists independently and each capsule can be numbered, when the pressure value of one capsule fluctuates greatly from other pressure values, it can be marked on the computer, and then removed manually or by a robot during the existing production process. At the same time, two or more weighing platforms 203 can be set in the weighing platform 203 of the present invention for replacement. When the capsule receiving holes of the capsule receiving plate 2035 on one weighing platform 203 are filled with capsules, another weighing platform 203 is replaced, and the replaced weighing platform 203 has time to weigh the capsules, preventing the reading of the pressure sensing patch from being affected by inertia when the capsules are dropped from the filling machine. By rotating and operating two or more weighing platforms 203, it is possible to let the capsules stand still after all the capsule receiving holes of the capsule receiving plate 2035 are filled with capsules, so that the pressure sensing patch obtains a stable reading. Further, in order to meet the requirement of the weighing platform 203 in this embodiment to receive capsules, the weighing mechanism 200 in this embodiment further includes a lead screw slide 201, and a connecting table 202 is slidably connected to the lead screw slide 201. The weighing platform 203 is slidably connected to the connecting table 202. The lead screw slide 201 and the connecting table 202 can realize the two-direction movement of the weighing platform 203. The weighing platform 203 can move in two directions, so that different capsule receiving holes on the capsule receiving plate 2035 can be aligned with the output port of the filling machine, and the capsules can be accurately put into the capsule receiving holes of the capsule receiving plate 2035 and fall on the trays 2034. Further, in order to prevent the plurality of weighing platforms 203 from interfering with each other during operation, the weighing platforms 203 in this embodiment are arranged front and back relative to the connecting table 202, and there is a height difference between a pair of front and back arranged weighing platforms 203.

[0033] Refer to Figure 6 Figure 6 , after the weighing of the capsules is completed, in order to facilitate the discharge of the capsules from the capsule receiving holes of the capsule receiving plate 2035, in this embodiment, a telescopic rod 2036 is further assembled on the upper surface of the connecting plate 2031, and a pin connecting piece is centrally provided on the lower surface of the movable plate 2033. The output end of the telescopic rod 2036 is connected to the pin connecting piece by a pin. The telescopic rod 2036 is used to push the movable plate 2033 to move towards the capsule receiving plate 2035, so that the tray 2034 enters the capsule receiving hole to eject the capsules.

[0034] Refer to Figure 3 Figure 3 , in order to realize the movement of the weighing platform 203, in this embodiment, a screw rod 2012 is connected to one side inside the lead screw slide 201 by a bearing, and one end of the screw rod 2012 penetrates through the side wall of the lead screw slide 201 and is connected to a motor 2011. A limiting rod is provided on the other side inside the lead screw slide 201; screw sleeves 2021 are symmetrically provided on the lower surface of the connecting table 202, and the screw sleeve 2021 on one side of the lower surface of the connecting table 202 is threadedly connected to the screw rod 2012, and the screw sleeve 2021 on the other side of the lower surface of the connecting table 202 is sleeved on the limiting rod. By driving one of the screw rods 2012 to rotate by the motor 2011, the screw sleeve 2021 sleeved on this screw rod 2012 can perform a threaded movement. Synchronously, the other screw sleeve 2021 on the lower surface of the connecting table 202 is sleeved on the limiting rod, and the inner diameter of the screw sleeve 2021 is larger than the diameter of the limiting rod, so as to play a constraining role on the screw sleeve 2021 on the screw rod 2012, thereby realizing the lateral movement of the connecting table 202 in one direction.

[0035] Refer to Figure 3 and Figure 4, in order to realize the lateral movement of the connecting table 202 in another direction, in this embodiment, a pair of rollers 2022 are connected to both inner side walls of the connecting table 202 through bearing seats. The length of the rollers 2022 is less than the width of the connecting table 202. The installation heights between a pair of rollers 2022 installed on the same side of the connecting table 202 are different. A crawler 2023 is sleeved between the rollers 2022 with the same height in the connecting table 202. A pair of weighing tables 203 are respectively fixedly connected to the two crawlers 2023. In this embodiment, the reciprocating movement of the crawler 2023 with different heights is used to realize the lateral movement of the weighing table 203 fixed on the crawler 2023 in another direction. The operation of the crawler 2023 is mainly achieved by fixedly connecting a second gear 2024 to the end of the roller 2022 on one side of the connecting table 202, and a third gear 2026 is engaged with the lower end of the second gear 2024. A driver 2025 is provided at the center of the third gear 2026, and the driver 2025 is fixed on the side of the connecting table 202. The third gear 2026 is driven to rotate by the driver 2025, and the rotating third gear 2026 drives the second gear 2024 to rotate synchronously. The second gear 2024 is connected to the roller 2022 to realize the operation of the crawler 2023 sleeved on the roller 2022.

[0036] Refer to Figure 1 , Figure 2 and Figure 7 , in the present utility model, a conveying mechanism 100 is further provided. The conveying mechanism 100 can be connected to the output port of an existing filling machine, so as to intermittently convey the filled capsules to the weighing mechanism 200 through the conveying mechanism 100. And in order to facilitate the conveying of the capsules, the conveying mechanism 100 is located below the output end of the weighing mechanism 200. The conveying mechanism 100 includes a feeding box 101, which is of a hollow structure inside. A dividing plate 1011 is rotatably connected inside the feeding box 101. An inlet hopper 102 is provided at the upper end of the feeding box 101, and the upper end of the inlet hopper 102 is located at the discharging opening of the soft capsule filling machine. An outlet 103 is provided at the lower end of the feeding box 101, and the outlet 103 is located above the weighing table 203. A motor is fixedly installed on the feeding box 101, and a fourth gear is fixedly sleeved on the driving end of the motor; a first gear 1012 meshing with the fourth gear is connected to the center of the dividing plate 1011 through a cylinder. The fourth gear driven by the motor drives the first gear 1012 to rotate. Since the diameter of the first gear 1012 is larger than that of the fourth gear, the dividing plate 1011 connected to the first gear 1012 rotates uniformly in the feeding box 101 and rotates relatively slowly. Thus, the capsules received through the inlet hopper 102 are collected in the disk grooves of the dividing plate 1011, and the capsules are discharged from the outlet 103 and enter the capsule receiving holes of the capsule receiving plate 2035 of the weighing table 203 as the dividing plate 1011 rotates.

[0037] The above content is a further detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present utility model.
