Description
Technical Field
[0001] This application relates to the field of filling technology, and in particular to a filling device. Background Technology
[0002] Filling is the process of injecting contents into a container through a pipe or nozzle. The contents can be liquid, semi-solid, or powdered. Containers can be plastic, glass, or metal bottles. Filling is widely used in the beverage, food, cosmetics, and pharmaceutical industries, and can be tailored to the characteristics of the product and packaging requirements to meet the needs of different industries and consumers.
[0003] The existing filling equipment includes a conveying mechanism, a weighing mechanism, and a filling mechanism. The weighing mechanism is mounted on the conveying mechanism. The filling mechanism is located above the conveying mechanism. First, the conveying mechanism transports multiple empty containers downwards to the filling mechanism. Then, the filling mechanism fills each of the empty containers with their contents. Next, the weighing mechanism weighs each of the filled containers. Finally, the conveying mechanism transports the multiple filled containers to the next process. When the weighing mechanism weighs the multiple filled containers, a certain distance should be maintained between each adjacent container to ensure accurate weight measurement. Therefore, a certain distance should be maintained between each adjacent empty container during transport.
[0004] The existing technical solutions mentioned above have the following drawbacks: when multiple empty containers are being transported, a certain distance needs to be reserved between each two adjacent empty containers, resulting in low filling efficiency. Summary of the Invention
[0005] To improve filling efficiency, this application provides a filling device.
[0006] This application provides a filling device, which adopts the following technical solution: A filling device, comprising: The first conveying mechanism is used to convey empty containers; The second conveying mechanism is located on one side of the first conveying mechanism and has the same conveying direction as the first conveying mechanism. It is used to convey filling containers. A weighing mechanism is located between the first conveying mechanism and the second conveying mechanism, and is used to weigh the filling containers; A filling mechanism, located above the weighing mechanism, is used to fill empty containers with contents; A position transfer mechanism is located on the side of the first conveying mechanism away from the second conveying mechanism. It is used to transfer empty containers on the first conveying mechanism to the weighing mechanism and to transfer filling containers on the weighing mechanism to the second conveying mechanism.
[0007] By adopting the above technical solution, empty containers are transported by the first conveying mechanism, eliminating the need for pre-reserved spacing between adjacent empty containers. A position transfer mechanism then transfers one of each pair of adjacent empty containers to the weighing mechanism. Next, the filling mechanism fills the multiple empty containers on the weighing mechanism with contents, and the weighing mechanism weighs each filled container. Afterward, the position transfer mechanism transfers the multiple filled containers on the weighing mechanism to the second conveying mechanism, which then transports the filled containers. Then, the first conveying mechanism moves the remaining empty containers slightly, a distance equal to the width of a single empty container. The position transfer mechanism then transfers the remaining empty containers to the weighing mechanism. The filling mechanism then fills the multiple empty containers on the weighing mechanism with contents, and the weighing mechanism weighs each filled container. Finally, the position transfer mechanism transfers the multiple filled containers on the weighing mechanism to the second conveying mechanism. This significantly improves filling efficiency, thereby increasing production cycle time.
[0008] This application further specifies that the weighing mechanism includes: The first support frame is disposed between the first conveying mechanism and the second conveying mechanism; Multiple weighing devices are evenly installed on the top of the first support frame along the length of the first support frame. The guide components, in multiple units, are installed on top of the weighing devices in a one-to-one correspondence to the weighing devices, and are used to restrict the direction of movement of empty / filled containers.
[0009] By adopting the above technical solution, the first support frame provides support. Multiple weighing devices can simultaneously weigh multiple filling containers, ensuring weighing efficiency. A certain distance is reserved between each pair of adjacent weighing devices to ensure weighing accuracy. During container movement, the guiding component not only guides the container but also prevents it from tipping to one side, making the container's position transfer smooth and stable.
[0010] This application further specifies that each guiding component includes: The base plate is installed on top of the weighing device; The first guide plate consists of two plates, each installed on a common side of the top of the base plate; There are two second guide plates, which are installed on the common other side of the top of the base plate and are set directly opposite the two first guide plates; the distance between each second guide plate and the corresponding first guide plate is adjustable.
[0011] By adopting the above technical solution, the distance between each second guide plate and its corresponding first guide plate can be adjusted to regulate the width of the channel. The channel width can be adjusted according to the width of a single container, improving the versatility of the weighing mechanism. Simultaneously, adjusting the channel width allows for adjustment of the forces exerted by the second and first guide plates on the container's sidewalls, thereby adjusting the frictional force acting on the container as it moves forward, thus preventing the container from tipping over.
[0012] This application further specifies that the weighing mechanism also includes: Multiple blocking components are evenly installed on the top of the first support frame along the length of the first support frame, and the multiple blocking components and multiple weighing devices are alternately arranged along the length of the first support frame. Multiple rolling components are evenly installed on the top of the first support frame along the length of the first support frame, and the multiple rolling components and multiple weighing devices are alternately arranged along the length of the first support frame.
[0013] By adopting the above technical solution, when the position transfer mechanism transfers one of two adjacent empty containers to the weighing mechanism, multiple blocking components can prevent the other empty container from moving or rotating due to friction, which helps to ensure the smoothness of subsequent production. When the position transfer mechanism transfers the filling container on the weighing mechanism to the second conveying mechanism, each rolling component not only reduces the moving friction of the corresponding filling container, but also provides support and guidance. This ensures the smooth movement of the filling container, prevents the filling container from tipping over or rotating at the outlet of the channel, and can also adjust the distance between two adjacent filling containers.
[0014] This application further specifies that each blocking component includes: The first support base is fixed to the top of the first support frame; There are two first support rods, both horizontally arranged, and each can be axially movable and mounted on the first support base. The support plate is fixed to the common end of the two first support rods and moves with the first support rods; Two baffles are installed on the side of the support plate away from the first support rod, which can be moved towards or away from each other.
[0015] This application further specifies that each scrolling component includes: The second support is fixed to the top of the first support frame; The second support rod is vertically installed and can be moved along the Y-axis direction on the second support base; The roller is rotatably mounted on the top of the second support rod and moves with the second support rod.
[0016] This application further specifies that the location transfer mechanism includes: The second support frame is located on the side of the first conveying mechanism away from the second conveying mechanism; Multiple push cylinders are evenly installed on the top of the second support frame along the length of the second support frame, and each cylinder can move along the length of the second support frame. There are multiple push plates, which are fixedly connected to the output shafts of multiple push cylinders one by one. They are used to push the corresponding empty containers on the first conveying mechanism to the weighing mechanism, and to push the corresponding filling containers on the weighing mechanism to the second conveying mechanism.
[0017] By adopting the above technical solution, the position of each push cylinder on the X-axis can be adjusted as needed to ensure the position transfer effect and efficiency. Multiple push plates are fixedly connected to the output shafts of multiple push cylinders in a one-to-one correspondence. Multiple push cylinders drive the corresponding push plates to move, pushing the corresponding empty containers on the first conveying mechanism onto the weighing mechanism, and can also push the corresponding filling containers on the weighing mechanism onto the second conveying mechanism.
[0018] This application further specifies that the filling mechanism includes: The third support frame is movable along the Z-axis and is positioned above the weighing mechanism; There are two first position adjustment components; one first position adjustment component is connected to one end of the third support frame, and the other first position adjustment component is connected to the other end of the third support frame; the two first position adjustment components are used to drive the corresponding ends of the third support frame to move along the Z-axis direction. The fourth support frame is movably mounted on the third support frame along the Z-axis. There are two lifting cylinders, which are respectively installed at opposite ends of the third support frame. The output shafts are respectively fixedly connected to opposite ends of the fourth support frame, and are used to drive the corresponding ends of the fourth support frame to move along the Z-axis. The fifth support frame is movably mounted on the fourth support frame along the Y-axis. There are two second position adjustment components, each mounted on the fourth support frame. One second position adjustment component is connected to one end of the fifth support frame, and the other second position adjustment component is connected to the other end of the fifth support frame. The two second position adjustment components are used to drive the corresponding ends of the fifth support frame to move along the Y-axis. Multiple mounting bases are evenly installed on the fifth support frame along the length of the fifth support frame, and each base can move along the length of the fifth support frame. There are multiple filling nozzles, each corresponding to a different mounting base. The liquid storage tank is located above the third support frame and is connected to multiple filling nozzles through multiple filling valves.
[0019] By adopting the above technical solution, each filling valve can precisely control the filling volume, and in conjunction with the weighing device, greatly improves filling accuracy. Two first position adjustment components can adjust the relative positions of the two ends of the third support frame in the Z-axis direction, thereby adjusting the initial positions of the fifth support frame, multiple mounting seats, and multiple filling nozzles in the Z-axis direction. Two second position adjustment components can adjust the relative positions of the two ends of the fifth support frame in the Y-axis direction, thereby adjusting the positions of the multiple mounting seats and multiple filling nozzles in the Y-axis direction. Two lifting cylinders drive the relative ends of the fourth support frame to move up and down, thereby moving the fifth support frame and multiple mounting seats up and down, and thus moving the multiple filling nozzles up and down, allowing each filling nozzle to insert into or detach from its corresponding empty container to complete the filling task. As needed, the position of each mounting seat in the X-axis direction can be adjusted to adjust the position of each filling nozzle in the X-axis direction. This ensures both filling efficiency and filling effect, and improves the versatility of the filling mechanism, making it compatible with various container models.
[0020] This application further specifies that the filling mechanism also includes: The sealing head consists of multiple sealing heads, each corresponding to a filling nozzle and installed inside the filling nozzle. Each sealing head can move up and down to open or close the corresponding filling nozzle. There are multiple sealing cylinders, each corresponding to a different mounting base. The output shaft is fixedly connected to a corresponding sealing head, and is used to drive the corresponding sealing head to move up and down.
[0021] By adopting the above technical solution, the opening and closing efficiency of the filling nozzle is guaranteed.
[0022] This application further specifies that: first stop bars are respectively provided on both opposite sides of the entrance of the first conveying mechanism; A second stop is provided on the side of the second conveying mechanism away from the first conveying mechanism.
[0023] In summary, the beneficial technical effects of this application are as follows: 1. Empty containers are transported by a first conveying mechanism, eliminating the need for spacing between adjacent containers. A position transfer mechanism then transfers one of the two adjacent empty containers to a weighing mechanism. The filling mechanism then fills the contents into the multiple empty containers on the weighing mechanism, and the weighing mechanism weighs each filled container. Next, the position transfer mechanism transfers the multiple filled containers from the weighing mechanism to a second conveying mechanism, which then transports them. The first conveying mechanism then moves the remaining empty containers slightly, a distance equal to the width of a single empty container. The position transfer mechanism then transfers the remaining empty containers to the weighing mechanism. The filling mechanism then fills the contents into the multiple empty containers on the weighing mechanism, and the weighing mechanism weighs each filled container. Finally, the position transfer mechanism transfers the multiple filled containers from the weighing mechanism to the second conveying mechanism. This significantly improves filling efficiency and, consequently, increases production cycle time.
[0024] 2. The first support frame provides support. Multiple weighing devices can simultaneously weigh multiple filling containers, ensuring weighing efficiency. A certain distance is reserved between each pair of adjacent weighing devices to ensure weighing accuracy. During container movement, the guide component not only guides the container but also prevents it from tipping to one side, making the container's position transfer smooth and stable.
[0025] 3. When the position transfer mechanism transfers one of two adjacent empty containers to the weighing mechanism, multiple blocking components prevent the other empty container from moving or rotating due to friction, thus ensuring smooth subsequent production. When the position transfer mechanism transfers the filling containers from the weighing mechanism to the second conveying mechanism, each rolling component reduces the moving friction of the corresponding filling container, provides support, and guides it. This ensures smooth movement of the filling containers, prevents them from tipping over or rotating at the channel exit, and adjusts the spacing between adjacent filling containers.
[0026] 4. Each filling valve can precisely control the filling volume, and in conjunction with the weighing device, greatly improves filling accuracy. Two first position adjustment components can adjust the relative positions of the two ends of the third support frame in the Z-axis direction, thereby adjusting the initial positions of the fifth support frame, multiple mounting seats, and multiple filling nozzles in the Z-axis direction. Two second position adjustment components can adjust the relative positions of the two ends of the fifth support frame in the Y-axis direction, thereby adjusting the positions of the multiple mounting seats and multiple filling nozzles in the Y-axis direction. Two lifting cylinders drive the relative ends of the fourth support frame to move up and down, thereby moving the fifth support frame and multiple mounting seats up and down, and thus moving the multiple filling nozzles up and down, allowing each filling nozzle to insert into or detach from its corresponding empty container to complete the filling task. As needed, the position of each mounting seat in the X-axis direction can be adjusted to adjust the position of each filling nozzle in the X-axis direction. This ensures both filling efficiency and effect, and improves the versatility of the filling mechanism, making it compatible with various container models. Attached Figure Description

[0029] It should be noted that an empty container refers to the container before filling. A filled container refers to the container after filling. After filling, subsequent processes such as labeling, boxing, and coding are carried out.
[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a filling device, including a first conveying mechanism 110, a second conveying mechanism 120, a weighing mechanism 130, a filling mechanism 140, and a position transfer mechanism 150. The first conveying mechanism 110 is used to convey empty containers. The second conveying mechanism 120 is disposed on one side of the first conveying mechanism 110, with the same conveying direction as the first conveying mechanism 110, and is used to convey filling containers. The weighing mechanism 130 is disposed between the first conveying mechanism 110 and the second conveying mechanism 120, and is used to weigh the filling containers. The filling mechanism 140 is disposed above the weighing mechanism 130, and is used to fill the empty containers on the weighing mechanism 130 with contents. The position transfer mechanism 150 is disposed on the side of the first conveying mechanism 110 away from the second conveying mechanism 120, and is used to transfer the empty containers on the first conveying mechanism 110 to the weighing mechanism 130, and to transfer the filling containers on the weighing mechanism 130 to the second conveying mechanism 120.
[0032] The working process and principle of the filling equipment are as follows: Empty containers are conveyed by the first conveying mechanism 110, without requiring any spacing between adjacent empty containers. The position transfer mechanism 150 transfers one of each pair of adjacent empty containers to the weighing mechanism 130. Then, the filling mechanism 140 fills the multiple empty containers on the weighing mechanism 130 with contents, and the weighing mechanism 130 weighs each filled container. Afterwards, the position transfer mechanism 150 transfers the multiple filled containers on the weighing mechanism 130 to the second conveying mechanism 120, which then conveys the filled containers. Next, the first conveying mechanism 110 moves the remaining empty containers slightly, by a distance equal to the width of a single empty container. Then, the position transfer mechanism 150 transfers the remaining empty containers to the weighing mechanism 130. Afterwards, the filling mechanism 140 fills the multiple empty containers on the weighing mechanism 130 with contents, and the weighing mechanism 130 weighs each filled container. Finally, the position transfer mechanism 150 transfers multiple filling containers from the weighing mechanism 130 to the second conveying mechanism 120. This significantly improves filling efficiency and, consequently, increases production cycle time.
[0033] Preferably, both the first conveying mechanism 110 and the second conveying mechanism 120 are chain conveyors.
[0034] Reference Figure 5 In one embodiment, the weighing mechanism 130 includes a first support frame 131, a plurality of weighing devices 132, and a guide assembly 133. The first support frame 131 is disposed between the first conveying mechanism 110 and the second conveying mechanism 120, serving a supporting function. The plurality of weighing devices 132 are evenly installed on the top of the first support frame 131 along its length, enabling simultaneous weighing of multiple filling containers and ensuring weighing efficiency. A certain distance is reserved between each pair of adjacent weighing devices 132 to ensure weighing accuracy. The plurality of guide assemblies 133 are installed on the top of the weighing devices 132 in a one-to-one correspondence, used to restrict the movement direction of empty / filled containers. During container movement, the guide assembly 133 serves both a guiding function and prevents the container from tipping to one side, making the container's position transfer smoother and more stable.
[0035] Reference Figure 5 and Figure 6In one embodiment, each guide assembly 133 includes a base plate 1331, two first guide plates 1332, and two second guide plates 1333. The base plate 1331 is fixed to the top of the weighing device 132. The two first guide plates 1332 are respectively installed on a common side of the top of the base plate 1331. The two second guide plates 1333 are respectively installed on the other common side of the top of the base plate 1331, facing each of the two first guide plates 1332. Each second guide plate 1333 and its corresponding first guide plate 1332 form a channel for the container to pass through. The spacing between each second guide plate 1333 and its corresponding first guide plate 1332 is adjustable to adjust the width of the channel. The width of the channel can be adjusted according to the width of a single container, improving the versatility of the weighing mechanism 130. At the same time, by adjusting the width of the channel, the force exerted by the second guide plates 1333 and the first guide plates 1332 on the sidewall of the container can be adjusted, thereby adjusting the friction force on the container's forward movement to prevent the container from tipping over. It should be noted that when weighing the filling container using the weighing device 132, the weight of the guide assembly 133 should be removed.
[0036] Preferably, two adjustment holes are formed on opposite sides of the base plate 1331. The bottom ends of the two first guide plates 1332 each have a first support foot, and each first support foot has a first mounting hole. Bolts and nuts are used to connect each first guide plate 1332 to the base plate 1331 through the first mounting holes and adjustment holes. The bottom ends of the two second guide plates 1333 each have a second support foot, and each second support foot has a second mounting hole. Bolts and nuts are used to connect each second guide plate 1333 to the base plate 1331 through the second mounting holes and adjustment holes. This allows the distance between each second guide plate 1333 and its corresponding first guide plate 1332 to be adjustable.
[0037] Preferably, the opposite sides of each first guide plate 1332 are bent away from the corresponding second guide plate 1333, and the opposite sides of each second guide plate 1333 are bent away from the corresponding first guide plate 1332. In this way, the sides of the first guide plate 1332 / second guide plate 1333 can be prevented from contacting the outer wall of the container, so as to avoid the sides from creating resistance to the movement of the container, and the container can be guided to slide smoothly into or out of the channel.
[0038] Reference Figure 5 and Figure 6In one embodiment, the weighing mechanism 130 further includes a plurality of blocking components 134 and a plurality of rolling components 135. The plurality of blocking components 134 are evenly mounted on the top of the first support frame 131 along its length, and the plurality of blocking components 134 and the plurality of weighing devices 132 are alternately arranged along the length of the first support frame 131. Each blocking component 134 is positioned near the entrance end of the channel formed by the corresponding guide component 133. When the position transfer mechanism 150 transfers one of two adjacent empty containers to the weighing mechanism 130, the plurality of blocking components 134 can prevent the other empty container from moving or rotating due to friction, thus ensuring smooth subsequent production. The plurality of rolling components 135 are evenly mounted on the top of the first support frame 131 along its length, and the plurality of rolling components 135 and the plurality of weighing devices 132 are alternately arranged along the length of the first support frame 131. Each rolling assembly 135 is positioned near the exit end of the channel formed by the corresponding guide assembly 133. When the position transfer mechanism 150 transfers the filling container on the weighing mechanism 130 to the second conveying mechanism 120, each rolling assembly 135 serves to reduce the moving friction of the corresponding filling container, provide support, and guide it. This ensures the smooth movement of the filling container, prevents the filling container from tipping over or rotating at the exit of the channel, and also adjusts the spacing between each pair of adjacent filling containers.
[0039] Preferably, such as Figure 5 and Figure 6 As shown, each blocking assembly 134 includes a first support base 1341, two first support rods 1342, a support plate 1343, and two blocking plates 1344. The first support base 1341 is fixed to the top of the first support frame 131. Both first support rods 1342 are horizontally arranged and axially movable on the first support base 1341. The support plate 1343 is fixed to the common end of the two first support rods 1342 and moves with them. The two blocking plates 1344 are movably mounted on the side of the support plate 1343 away from the first support rods 1342, facing each other or moving away from each other. The position of the two blocking plates 1344 in the Y-axis direction and the spacing between them can be adjusted as needed to accommodate containers of different lengths and widths. This effectively improves the versatility of the blocking assembly 134 and ensures effective interception.
[0040] Preferably, such as Figure 5 and Figure 6As shown, each rolling assembly 135 includes a second support base 1351, a second support rod 1352, and a roller 1353. The second support base 1351 is fixed to the top of the first support frame 131. The second support rod 1352 is vertically arranged and movably mounted on the second support base 1351 along the Y-axis. The roller 1353 is rotatably mounted on the top of the second support rod 1352 and moves with the second support rod 1352. This effectively improves the versatility of the rolling assembly 135.
[0041] Reference Figure 7 In one embodiment, the position transfer mechanism 150 includes a second support frame 151, a plurality of push cylinders 152, and a plurality of push plates. The second support frame 151 is disposed on the side of the first conveying mechanism 110 away from the second conveying mechanism 120, and serves as a support. The plurality of push cylinders 152 are evenly installed on the top of the second support frame 151 along the length direction of the second support frame 151, and are each movable along the length direction of the second support frame 151. In this way, the position of each push cylinder 152 on the X-axis can be adjusted as needed to ensure the position transfer effect and efficiency. The plurality of push plates are fixedly connected to the output shafts of the plurality of push cylinders 152 in a one-to-one correspondence. The plurality of push cylinders 152 drive the corresponding push plates to move, so as to push the corresponding empty containers on the first conveying mechanism 110 onto the weighing mechanism 130, and can push the corresponding filling containers on the weighing mechanism 130 onto the second conveying mechanism 120.
[0042] Reference Figure 8 and Figure 9In one embodiment, the filling mechanism 140 includes a third support frame 141, two first position adjustment components 142, a fourth support frame 143, two lifting cylinders 144, a fifth support frame 145, two second position adjustment components 146, multiple mounting seats 147, multiple filling nozzles 148, and a liquid storage tank 1491. The third support frame 141 is movably disposed above the weighing mechanism 130 along the Z-axis. One of the first position adjustment components 142 is connected to one end of the third support frame 141, and the other first position adjustment component 142 is connected to the other end of the third support frame 141. The two first position adjustment components 142 are respectively used to drive the corresponding ends of the third support frame 141 to move along the Z-axis. The fourth support frame 143 is movably mounted on the third support frame 141 along the Z-axis. Two lifting cylinders 144 are respectively installed at opposite ends of the third support frame 141, and their output shafts are respectively fixedly connected to opposite ends of the fourth support frame 143, for driving the corresponding ends of the fourth support frame 143 to move along the Z-axis. A fifth support frame 145 is movably installed on the fourth support frame 143 along the Y-axis. Two second position adjustment components 146 are respectively installed on the fourth support frame 143. One second position adjustment component 146 is connected to one end of the fifth support frame 145, and the other second position adjustment component 146 is connected to the other end of the fifth support frame 145. The two second position adjustment components 146 are respectively used to drive the corresponding ends of the fifth support frame 145 to move along the Y-axis. Multiple mounting seats 147 are evenly installed on the fifth support frame 145 along its length, and are each movable along the length of the fifth support frame 145. Multiple filling nozzles 148 are installed on the mounting seats 147 one-to-one with the multiple mounting seats 147. The storage tank 1491 is used to store liquid products. The storage tank 1491 is positioned above the third support frame 141 and is connected to multiple filling nozzles 148 via multiple filling valves 1492. Each filling valve 1492 can precisely control the filling volume, and in conjunction with the weighing device 132, greatly improves filling accuracy. Two first position adjustment components 142 can adjust the relative positions of the two ends of the third support frame 141 in the Z-axis direction to adjust the initial positions of the fifth support frame 145, multiple mounting seats 147, and multiple filling nozzles 148 in the Z-axis direction. Two second position adjustment components 146 can adjust the relative positions of the two ends of the fifth support frame 145 in the Y-axis direction to adjust the positions of the multiple mounting seats 147 and multiple filling nozzles 148 in the Y-axis direction. Two lifting cylinders 144 drive the opposite ends of the fourth support frame 143 to move up and down, thereby driving the fifth support frame 145 and multiple mounting seats 147 to move up and down, which in turn drives multiple filling nozzles 148 to move up and down, so that each filling nozzle 148 can be inserted into or removed from the corresponding empty container to complete the filling task.The position of each mounting base 147 in the X-axis direction can be adjusted as needed to adjust the position of each filling nozzle 148 in the X-axis direction. In this way, filling efficiency and filling effect are guaranteed, and the versatility of the filling mechanism 140 is improved, making the filling mechanism 140 compatible with a variety of container models.
[0043] Preferably, as shown in Figure 9, the filling mechanism 140 further includes multiple sealing heads (not shown) and multiple sealing cylinders 1493. The multiple sealing heads are installed in the filling nozzles 148 in a one-to-one correspondence with the multiple filling nozzles 148, and are capable of moving up and down to open or close the corresponding filling nozzle 148. The multiple sealing cylinders 1493 are installed on the mounting seats 147 in a one-to-one correspondence with the multiple mounting bases 147, and the output shafts are fixedly connected to the multiple sealing heads in a one-to-one correspondence, used to drive the corresponding sealing heads to move up and down to open or close the corresponding filling nozzles 148. This ensures the opening and closing efficiency of the filling nozzles 148.
[0044] Preferably, refer to Figure 2 and Figure 7 First baffles 111 are respectively provided on both sides of the entrance of the first conveying mechanism 110. The first baffles 111 guide the movement of the empty container and prevent the empty container from tipping over, thus preventing the empty container from detaching from the first conveying mechanism 110. A second baffle 121 is provided on the side of the second conveying mechanism 120 away from the first conveying mechanism 110. When the filling container moves along the width direction of the second conveying mechanism 120, the second baffle acts as an interceptor to prevent the filling container from detaching from the second conveying mechanism 120. When the filling container moves along the length direction of the second conveying mechanism 120, the second baffle 121 guides the movement of the filling container.
[0045] The implementation principle of this embodiment is as follows: An empty container is conveyed by a first conveying mechanism 110, with no additional spacing required between adjacent empty containers. A position transfer mechanism 150 transfers one of the two adjacent empty containers to a weighing mechanism 130. Then, a filling mechanism 140 fills the contents of the multiple empty containers on the weighing mechanism 130, and the weighing mechanism 130 weighs each filled container. Afterward, the position transfer mechanism 150 transfers the multiple filled containers on the weighing mechanism 130 to a second conveying mechanism 120, which then conveys the filled containers. Next, the first conveying mechanism 110 moves the remaining empty containers slightly, the distance being the width of a single empty container. Then, the position transfer mechanism 150 transfers the remaining empty containers to the weighing mechanism 130. Afterward, the filling mechanism 140 fills the contents of the multiple empty containers on the weighing mechanism 130, and the weighing mechanism 130 weighs each filled container. Finally, the position transfer mechanism 150 transfers multiple filling containers from the weighing mechanism 130 to the second conveying mechanism 120. This significantly improves filling efficiency and, consequently, increases production cycle time.
