Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filling equipment, and more specifically, to a filling mechanism. Background Art
[0002] During product production, most liquid products and some granular products are packaged in filling bodies. During packaging, filling equipment is generally used in the production line to improve production efficiency, among which the filling mechanism is the core mechanism of the filling mechanism.
[0003] The filling mechanism of common filling equipment is mostly simple in structure. In order to ensure the stability of the material amount during filling, most filling mechanisms will be equipped with a separate quantitative structure. The feeding equipment will not directly feed the material into the box tank packaging, but will first feed the material into the quantitative structure. After the quantitative structure is filled, the feeding will be stopped, and a fixed amount of material will be discharged from the quantitative structure into the tank, thereby ensuring quantitative filling. However, in this type of structure, the filling volume is affected by the quantitative structure. Common quantitative structures are mostly just containers with fixed structures. Therefore, the filling volume of the same equipment is uniform. When responding to the packaging needs of tanks of different specifications, different equipment needs to be replaced. For filling, the applicability of the equipment is not high and it is rather troublesome. In addition, when discharging the material in the quantitative structure, in order to avoid material residue, the piston structure is generally controlled to move by a power device to squeeze out the material, but the piston structure can only clean the residual material in the quantitative structure. Sometimes, when the material passes through the discharge port, it will remain on the pipe wall of the discharge port, affecting the accuracy of the filling amount. In addition, in the production line, the tank body is generally automatically transported by transportation equipment to participate in the filling. Sometimes the tank body may not be aligned with the discharge end of the filling equipment, which may cause the material to spray onto the equipment, and the material in the tank body is also easy to splash to the surrounding area and pollute the filling equipment.

[0016] (III) Beneficial effects
[0017] Compared with the prior art, the utility model provides a filling mechanism, which has the following beneficial effects:
[0018] 1. A quantitative structure is provided by arranging a metering cylinder, a piston block and a first cylinder. The movement of the first cylinder is controlled by the cooperation between the moving plate and the adjusting screw rod. The first cylinder moves, and the first cylinder drives the piston block to move together through the piston push rod.

When the tank block is full, the sealing plug contacts the tank mouth of the tank body to block the periphery of the discharge port and prevent the material from splashing out.

When the equipment is working, the internal space of the metering cylinder 2 is adjusted according to the filling demand, and the adjusting screw 6 is controlled to rotate so that the adjusting screw 6 cooperates with the moving plate 7 to provide power for the movement of the moving plate 7, so that the moving plate 7 moves with the first cylinder 8, and the first cylinder 8 drives the piston block 5 to move, changing the distance between the piston block 5 and the inner wall of the metering cylinder 2, thereby adjusting the volume of the metering cylinder 2, opening the control valve 4, and introducing the material into the metering cylinder 2 through the feeding structure, so that the material enters the metering cylinder 2 from the feed pipe 3, and under the restriction of the piston block 5, only a certain amount of material can enter. After the metering cylinder 2 is filled, the control valve 4 is closed.
[0033] More specifically, the first cylinder 8 cooperates with the piston block 5, and the first cylinder 8 pushes the piston block 5 to move, so that the piston block 5 cooperates with the metering cylinder 2 to discharge the material in the metering cylinder 2 from the discharge port 10, and the piston block 5 will ensure that the material remaining on the inner wall of the metering cylinder 2 is discharged. After the piston block 5 moves to the inner wall of the metering cylinder 2, the matching groove 11 is aligned with the discharge port 10, and the mobile piston 13 is driven to move by the second cylinder 12, so that the mobile piston 13 enters the discharge port 10 and pushes out the material on the inner wall of the discharge port 10.

[0042] Please refer to Figure 4 As a further implementation of the piston push rod: a conducting groove 22 is opened in the piston push rod 9, and the conducting groove 22 is connected with the matching groove 11.
[0043] Specifically, the space provided by the conducting groove 22 enables control structures such as electrical and air pipes to cooperate with the second cylinder 12 .

[0047] Specifically, the discharge of the material from the discharge port 10 is controlled by the ball valve 25. When the material is filled into the metering cylinder 2, the discharge port 10 is blocked by the ball valve 25 to prevent the material from flowing out. During filling, the ball valve 25 rotates and cooperates with the discharge port 10 through the through hole 26 to discharge the material from the discharge port 10. The specification of the through hole 26 is the same as the inner diameter of the discharge port 10, which is convenient for cooperating with the movable piston 13.
[0048] In summary, when the overall equipment is in use (or running):
[0049] When the device is used, the mounting frame 1 is mounted on the control device, the filling and filling mechanism is supported by the mounting frame 1, the feed pipe 3 is connected with the external feeding structure, and the first cylinder 8, the second cylinder 12, the control valve 4, the ball valve 25 and other devices are connected with the external control device. When the device is working, the internal space of the metering cylinder 2 is adjusted according to the filling requirements. By operating the rotating disk 21, the adjusting screw rod 6 can be controlled to rotate, so that the adjusting screw rod 6 cooperates with the moving plate 7 to provide power for the movement of the moving plate 7. The sliding ring 19 cooperates with the sliding rail 18, and the sliding ring 19 can only move along the sliding rail 18. , so that the sliding rail 18 guides the movement of the movable plate 7 to ensure that the movement of the movable plate 7 remains stable, and under the blocking of the support plate 20, the movable plate 7 can be prevented from separating from the sliding rail 18, so that the movable plate 7 moves with the first cylinder 8, and the first cylinder 8 drives the piston block 5 to move, and changes the distance between the piston block 5 and the inner wall of the metering cylinder 2, thereby adjusting the volume of the metering cylinder 2, and selecting a guide cover 14 with a suitable curvature according to the structure of the filling tank body, through the cooperation of the mounting ring 16 and the mounting plate 17, the guide cover 14 is fixed to the discharge port 10 by the mounting bolts, so that the guide cover 14 and the sealing plug 15 cooperate with the discharge port 10.
[0050] When performing the filling operation, the control valve 4 is opened, and the material is introduced into the metering cylinder 2 through the feeding structure, so that the material enters the metering cylinder 2 from the feeding pipe 3. Under the restriction of the piston block 5, a certain amount of material is filled, and during the filling process, the discharge port 10 is blocked by the ball valve 25 to prevent the material from flowing out. During the filling process, the filling mechanism is driven down by the control device, so that the discharge port 10 is inserted into the filling tank body, and during the descending process, the guide cover 14 contacts the tank body at the lower end, and the tank body mouth is not in contact with the discharge port. When the material port 10 is aligned, the can body is guided to make a fine adjustment based on its own curvature, so that the can body is aligned with the material port 10, and the front end of the material port 10 extends into the can body. When the material in the metering cylinder 2 is about to be filled, the equipment descends again, so that the sealing plug 15 blocks the other part of the can body port to prevent the material from splashing out during filling. In general filling processing, the can body will not be completely filled. Therefore, when the sealing plug 15 blocks the can body port, the filling is about to end. The can body material is generally tough, and there is no need to worry about air pressure problems. After the filling is completed, the control valve 4 is closed and the filling operation is performed. The ball valve 25 is rotated to cooperate with the discharge port 10 through the through hole 26 to discharge the material from the discharge port 10. The first cylinder 8 is driven to cooperate with the piston block 5. The first cylinder 8 pushes the piston block 5 to move through the piston push rod 9, so that the piston block 5 cooperates with the quantitative cylinder 2 to discharge the material in the quantitative cylinder 2 from the discharge port 10, and the piston block 5 will ensure that the residual material on the inner wall of the quantitative cylinder 2 is discharged. After the piston block 5 moves to the inner wall of the quantitative cylinder 2, The matching groove 11 is aligned with the discharge port 10, and the movable piston 13 is driven to move by the second cylinder 12, so that the movable piston 13 enters the discharge port 10, and the residual material on the inner wall of the discharge port 10 and the through hole 26 is pushed out, and the movable piston 13 contacts with the surrounding through the sliding sealing ring 23 to facilitate the discharge of the material in the discharge port 10, thereby ensuring that the material is completely discharged. In addition, when filling the material into the metering cylinder 2, the sliding sealing ring 23 cooperates with the sliding sealing groove 24 to prevent the material from entering the matching groove 11.
[0051] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
