Description
Technical Field
[0001] This utility model relates to the field of filling equipment technology, specifically to a weighing platform assembly for a filling machine and a semi-automatic filling machine. Background Technology
[0002] In the field of packaging machinery technology, filling machines are common equipment, mainly used to fill liquid or powdered materials into containers. Existing filling machines use a weighing platform to weigh the container during filling, so that when the specified weight is reached, feedback is sent to the filling system to stop filling. At the same time, in order to facilitate the removal of the container after filling, rollers are installed on the support platform supporting the container. For example, the bottled water filling and sterilization integrated machine disclosed in CN119750478A uses a support platform with rollers. This allows the container to be easily removed from the filling machine by dragging it outward after it is full. However, with the above structure, when the container is placed in the filling machine, it is not possible to accurately position the inlet of the container, especially for containers of different sizes, at the bottom of the filling gun. Utility Model Content
[0003] To address the problem of difficulty in positioning the container inlet to the bottom of the filling gun when placing containers, especially containers of different sizes, into a filling machine, this utility model provides a weighing platform assembly for a filling machine, and also provides a filling machine using the weighing platform assembly, which is applicable to containers of various sizes and facilitates positioning the container inlet to the bottom of the filling gun when placing the container into the filling machine.
[0004] The technical solution is as follows: a weighing platform assembly for a filling machine includes a support platform for supporting containers. The support platform is located below the filling gun and is equipped with rollers. When filling is required, the container is placed on the support platform in a front-to-back direction. The supporting platform is characterized by having a positioning assembly at its rear. The positioning assembly includes locking posts and limiting blocks. There are two or more locking posts, each fixedly connected to the support platform. The limiting blocks have connecting holes corresponding to the position and size of the locking posts. The locking posts are inserted into the connecting holes to mount the limiting blocks on the support platform. There are multiple limiting blocks, and the shape of each limiting block corresponds to the shape of containers of different sizes. When the container is placed into the filling machine, the limiting blocks abut against the rear of the container, positioning the container inlet directly below the filling gun.
[0005] Furthermore, the positioning component also includes a pad, the front end of which is provided with a positioning notch, the shape of which corresponds to the shape of the container, the pad is located at the bottom of the positioning notch, and the height of the pad is the same as the height of the roller.
[0006] Furthermore, the weighing platform assembly also includes a mounting platform and a weighing scale. The weighing scale is fixed inside the mounting platform through a connection hole on the side of the mounting platform. A baffle is provided on the top of the mounting platform. The length and width of the baffle are greater than the length and width of the mounting platform, respectively, and it is used to cover the connection hole on the side of the mounting platform in the vertical direction.
[0007] A semi-automatic filling machine includes a filling actuator, characterized in that it further includes the aforementioned weighing platform assembly.
[0008] Furthermore, the filling execution mechanism includes a material gun and a vertical displacement mechanism. The vertical displacement mechanism is used to drive the material gun to move vertically. The vertical displacement mechanism is connected to the material gun through a quick-release plate. A retaining plate is connected to the rear end of the material gun. The left and right sides and the bottom of the quick-release plate extend forward and bend to form retaining plate grooves. The retaining plate connects the material gun to the quick-release plate by inserting into the retaining plate grooves.
[0009] Furthermore, during filling, a waste gas recovery mechanism is provided above the container. The waste gas recovery mechanism includes an air intake pipe and an air baffle. The material gun passes through the air baffle and the air intake pipe. The air baffle is used to block the gas overflowing from the container inlet. The air intake pipe is located below the air baffle and its intake port is facing upwards to extract the blocked gas.
[0010] Beneficial effects: Different container sizes correspond to different limiting blocks, ensuring that when the container contacts the limiting block, the container inlet is positioned directly below the dispensing gun. Simply controlling the vertical displacement mechanism to lower the gun allows it to align with the container inlet for filling, simplifying the process. Additionally, the limiting blocks offer other advantages: the positioning notch of the limiting block corresponds to the container shape, increasing container stability; and the use of padding blocks fills any excessively large gaps after limiting block replacement, preventing gaps behind the rollers that could lead to container tipping due to lack of support.

[0017] like Figure 3 , Figure 4 The scale assembly 1 of a filling machine shown includes a support platform 101 for supporting a container 100. The support platform 101 is located below the filling gun 201. Rollers 102 are provided on the support platform 101. When filling is required, the container 100 is placed on the support platform 101 from front to back, that is, pushed into the filling machine. A positioning assembly is provided at the rear of the support platform 101. The positioning assembly includes locking pins 103 and limiting blocks 104. There are two or more locking pins 103, each of which is fixedly connected to the support platform 101. Next, the limiting block 104 is provided with a connecting hole corresponding to the position and size of the locking post 103. The locking post 103 is inserted into the connecting hole to install the limiting block 104 on the support platform 101. Two or more locking posts 103 can prevent the limiting block 104 from rotating. There are multiple limiting blocks 104, and the shape of each limiting block corresponds to the shape of different specifications of containers. When the container 100 is placed in the filling machine, the limiting block 104 abuts against the rear of the container 100 and makes the container inlet located directly below the material gun 201.
[0018] With this setup, the corresponding limiting block 104 can be selected according to the container specifications before filling. Since the limiting block 104 mainly serves a positioning function, it can be installed simply by fitting it onto the locking post 103, making it convenient to use. When pushing the container 100 into the filling machine, the use of rollers 102 reduces friction, making it easier to push the container 100 in, and also reduces fine particles generated by sliding friction, ensuring the purity of the packaged solution. The operator only needs to continue pushing the container 100 until it contacts the limiting block 104 and cannot be pushed any further. At this point, the pre-designed size of the limiting block 104 ensures that the container inlet is located below the material gun 201. The vertical displacement mechanism 202 directly drives the material gun 201 down for filling, eliminating the need for workers to manually adjust the position of the material gun. This is especially suitable for filling materials with high cleanliness or hazardous materials such as acids.
[0019] In addition, the positioning component also includes a pad 105. The front end of the limiting block 104 has a positioning notch, the shape of which corresponds to the shape of the container 100. The positioning notch can extend to the side of the container 100 to a certain extent, thereby increasing the stability of the container 100. The pad 105 is located at the bottom of the positioning notch, and the height of the pad 105 is the same as the height of the roller 102. When... Figure 3 Replace the limit block 104 in the middle with Figure 4When using the limiting block 104, the use of the pad block 105 can prevent the gap from appearing due to the expansion of the positioning gap, thereby preventing the bottom of the container from falling into the gap and causing it to tip over.
[0020] Meanwhile, when used for filling hazardous materials such as acids, the weighing platform assembly also includes a mounting platform 106 and a weighing scale. The weighing scale is fixed inside the mounting platform through a connection hole 108 on the side of the mounting platform. A baffle 107 is provided on the top of the mounting platform 106. The container 100 is pressed onto the weighing scale by rollers 102, a support platform 101, and the baffle 107 (preferably, the weighing scale is tare before use to remove the weight of the rollers 102, the support platform 101, and the baffle 107). The length and width of the baffle 107 are larger than the length and width of the mounting platform, and it is used to vertically cover the connection hole 108 on the side of the mounting platform 106. In this way, all screws are concealed and protected by the baffle 107. Even if the container tipps over, the packaging liquid cannot corrode the screws distributed under this structure. This mechanism makes the weighing platform surface free of screws and other holes, indirectly protecting the weighing platform from corrosion by the packaging liquid.
[0021] This solution also provides, for example Figure 1 , Figure 2 The semi-automatic filling machine shown includes a filling actuator 2 and a weighing platform assembly 1, combined with... Figure 5 , Figure 6 The filling actuator 2 includes a material gun 201 and a vertical displacement mechanism 202. Figure 1 , Figure 2 The feed gun 201 is not connected to the feed tube (in actual use, the feed tube is connected to the feed gun 201). The vertical displacement mechanism 202 (e.g., a cylinder) is used to drive the feed gun 201 to move vertically. The vertical displacement mechanism 202 is connected to the feed gun 201 through the quick-release plate 203. The rear end of the feed gun 201 is connected to the retaining plate 204. The left and right sides and the bottom of the quick-release plate 203 extend forward and bend to form retaining plate grooves 205. The retaining plate 204 connects the feed gun 201 to the quick-release plate 203 by inserting it into the retaining plate groove 205. With this design, when it is necessary to replace the feed gun, the feed gun 201 can be replaced by inserting the retaining plate 204 into the quick-release plate 203. It is very convenient to use. The retaining plate groove 205 also has a positioning function, so that the feed gun 201 remains vertical.
[0022] When used for filling hazardous materials such as acids, the top of container 100 is also equipped with... Figure 5The waste gas recovery mechanism 3 shown includes an intake pipe 301 and a baffle 302. The filling gun 201 passes through the baffle 302 and the intake pipe 301. The baffle 302 is used to block and collect the gas overflowing from the inlet of the container 100. The intake pipe 301 is located below the baffle 302 with its intake port facing upwards, used to extract the blocked gas, thereby protecting the production environment and preventing the overflowing gas from polluting the air. In addition, the filling machine is also equipped with a cleaning box 4, which serves to collect waste liquid when the gun head needs to be cleaned in preparation for production change. This allows for cleaning and filling simultaneously, greatly improving work efficiency. Preferably, the filling machine also adopts an intelligent control system. This system can monitor the working status of the gun in real time. Once an abnormality is detected, it can immediately issue an alarm and automatically adjust, thereby ensuring the stability of the gun head and improving the filling quality.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
