Description

Technical Field

[0001] The utility model relates to the field of filling equipment, in particular to a multi-head leak-proof filling machine. Background Art

[0002] Filling machines are a small category of packaging machines, which are mainly used to fill liquid into multiple packaging bottles through filling heads. When filling liquid, existing multi-head filling machines may leak due to the sealing of the filling heads, which will cause liquid dripping, resulting in dirty countertops and waste.

[0003] The prior art discloses a multi-head sauce filling machine with application number: CN202023039670.4. By installing an industrial camera to monitor the filling head in real time, it is convenient for technicians to retrieve video recordings and quickly identify leaking filling heads, saving time and effort and facilitating maintenance. The sauce dripping from the filling head passes through the conveyor belt into the collecting cover and is collected in the collecting trough of the waste box, which is convenient for unified treatment and keeps the upper surface of the machine base clean.

[0004] However, the existing technology cannot promptly identify empty spaces during bottle conveying, resulting in empty liquid filling. Although excess liquid can pass through the conveyor belt into the collecting hood, the storage space of the collecting trough is limited, which will still lead to liquid waste and increase production costs. Utility Model Content

[0005] In view of the above problems, the utility model provides a multi-head leak-proof filling machine, which provides a slidable outer shell at the liquid outlet pipe and the liquid outlet. During filling, the bottle mouth resists the outer shell, so that the barrier plate is separated from the bottom of the liquid outlet to fill the liquid. The machine can also identify empty spaces, avoid liquid waste, and ensure the orderly progress of the filling work.

[0006] The technical solution of the utility model is as follows:

[0007] A multi-head leak-proof filling machine comprises a base and a conveyor belt, wherein a support frame is mounted on the base, a filling box is mounted on the support frame, and a filling device is provided at the bottom of the filling box;

[0008] The filling device comprises a transmission pipeline connected to the filling box, a lifting pipe is slidably sleeved on the transmission pipeline, a shunt pipe is fixedly connected at the bottom of the lifting pipe, and the shunt pipe is connected to the transmission pipeline, and a plurality of filling heads are provided at the bottom of the shunt pipe;

[0009] The filling head includes a liquid outlet pipe connected to the diverter pipe and a liquid outlet provided at the bottom of the liquid outlet pipe, the liquid outlet pipe and the liquid outlet are slidably connected to the outside of an outer shell body matching their shapes, a group of fixed blocks are respectively provided on the outer wall of the liquid outlet pipe and the inner wall of the outer shell body, the two groups of fixed blocks are arranged up and down, and a spring is provided between the two groups of fixed blocks, a baffle plate is slidably installed in the liquid outlet, a steel mesh is fixedly installed at the bottom of the outer shell body, a connecting rod is provided between the steel mesh and the baffle plate, and the bottom of the liquid outlet is truncated cone-shaped, the outer diameter of the baffle plate is larger than the inner diameter of the bottom of the liquid outlet, and smaller than the maximum inner diameter of the liquid outlet.

[0010] The working principle of the above technical solution is as follows:

[0011] When the utility model is used, a multi-head leak-proof filling machine is transported to the bottom of the filling device via a conveyor belt, and the lifting tube moves downward so that the outer shell is against the bottle mouth of the packaging bottle, and the liquid outlet continues to move downward, the spring is compressed, the blocking plate and the connecting rod remain stationary, and the blocking plate is away from the bottom of the liquid outlet, and the liquid flows into the packaging bottle from the liquid outlet to complete the filling of the liquid, and the outer shell is consistent with the liquid outlet tube and the liquid outlet tube in shape, and the bottom of the outer shell and the bottom of the liquid outlet tube are both truncated cone-shaped, and the bottom of the outer shell can be extended into the bottle mouth to prevent the liquid from flowing out. When there is no packaging bottle below, the outer shell will not be against the bottle mouth, and the liquid will not flow out. After the liquid filling is completed within the set time, the lifting tube rises, thereby driving the liquid outlet to move upward until the blocking plate is located at the bottom of the liquid outlet. Under the action of the spring, the blocking plate is fixed at the bottom of the liquid outlet to block the liquid from flowing out. Then, as the filling device moves upward and resets, the conveyor belt continues to work to transport the packaging bottles. This device will repeat the above operations to perform filling work, and the filled liquid is transmitted to the other side, where the staff will perform the next step of processing.

[0012] The utility model blocks the outer shell body with the bottle mouth during filling, so that the blocking plate is separated from the bottom of the liquid outlet to carry out liquid filling. When a vacant space appears, the outer shell body is not blocked, so that the blocking plate is always located at the bottom of the liquid outlet, thereby avoiding liquid waste and ensuring the orderly progress of the filling work.

[0013] In a further technical solution, the bottom of the outer shell is slidably and sealedly connected to the liquid outlet to prevent liquid from flowing into the outer shell during filling, thereby reducing waste and pollution.

[0014] In a further technical solution, a fixing rod is provided on the support frame, a motor 1 is installed on the fixing rod, a gear is provided at the output end of the motor 1, the gear is accommodated between the transmission pipe and the lifting tube, a rectangular rack matching the gear is provided on the lifting tube, the bottom end of the transmission pipe is slidingly and sealingly connected to the inside of the lifting tube, the gear is driven to rotate by the motor 1, thereby driving the lifting tube to move up and down, so as to realize the outer shell supporting and releasing the bottle mouth.

[0015] In a further technical solution, a hemispherical guide roller is provided at the upper end of the transmission pipe, and a second motor for driving the guide roller to rotate is fixedly installed on the outside of the transmission pipe. The second motor drives the hemispherical guide roller to rotate, thereby controlling the time for liquid to flow into the transmission pipe, thereby maintaining quantitative filling.

[0016] In a further technical solution, the conveyor belt is provided with a plurality of limit grooves for placing bottle bodies, the center spacing of the limit grooves is the same as the spacing between adjacent filling heads, fixed plates are provided on both sides of the conveyor belt, the fixed plates are mounted on the base, a plurality of rollers are provided on the inner side of the fixed plates, the limit grooves are provided for placing bottle bodies, and the fixed plates keep the packaging bottles in a straight line, which can effectively prevent the problem of bottle displacement during transportation causing subsequent misalignment of the bottle mouth with the filling head, and the provision of rollers can facilitate the transportation of packaging bottles.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model blocks the outer shell with the bottle mouth during filling, so that the blocking plate is separated from the bottom of the liquid outlet to fill the liquid. When there is a vacancy, the outer shell is not blocked, so that the blocking plate is always located at the bottom of the liquid outlet, thereby avoiding liquid waste and ensuring the orderly progress of the filling work;

[0019] 2. The bottom of the liquid outlet pipe is in a truncated cone shape, and the outer shell is consistent with the shape of the liquid outlet pipe and the liquid outlet pipe, so that when the outer shell and the bottle mouth are against each other, the bottom of the outer shell can extend into the bottle mouth to prevent the liquid from flowing out;
