DETAILED DESCRIPTION

[0036] (Example 1)

[0037] See Figures 1 to 7 The automatic switching filling machine for the feeding nozzle of this embodiment, which can perform filling and cleaning at the same time, comprises a frame 1 and a filling conveying line 2, a filling mechanism 3 and a cleaning mechanism 4 arranged on the frame 1.

[0038] The cleaning mechanism 4 includes a liquid inlet and a collection box 4-1. The filling mechanism 3 and the liquid inlet are each provided with two. The filling mechanism 3 includes a feeding part 3-1 and a feeding part 3-2 connected to the feeding part 3-1. The two liquid inlets are respectively connected to the feeding parts 3-1 of the two filling mechanisms 3. The feeding parts 3-2 of the two filling mechanisms 3 are both rotatably arranged on the frame 1, and each feeding part 3-2 is driven to operate by a feeding part driving mechanism 5. The collection box 4-1 is provided with a cleaning liquid receiving pipe 3-3 corresponding to the feeding parts 3-2 of the two filling mechanisms 3.

[0039] The feeding part 3-1 of the filling mechanism 3 includes a feeding pipe 3-1-1 and a feeding control valve 3-1-2 arranged on the feeding pipe 3-1-1. The feeding pipe 3-1-1 is connected to the distribution pipe 3-1-3. The distribution pipe 3-1-3 is connected to the unloading part 3-2 through a unloading hose, so that multiple unloading nozzles 3-2-3 can be used for filling, thereby improving work efficiency.

[0040] The material discharge part 3-2 includes a mounting seat 3-2-1, a fixed bracket 3-2-2 and a material discharge nozzle 3-2-3 connected to the distribution pipe 3-1-3. The mounting seat 3-2-1 is arranged on the frame 1 with adjustable height to be suitable for filling products of different specifications. One end of the fixed bracket 3-2-2 is rotatably mounted on the mounting seat 3-2-1. The material discharge nozzle 3-2-3 is fixed to the other end of the fixed bracket 3-2-2.

[0041] Slide rails 1-1 are provided on both sides of the frame 1. The two ends of the mounting seat 3-2-1 are respectively slidably connected in the two slide rails 1-1 to ensure the stability of the movement of the mounting seat 3-2-1. The top of the frame 1 is provided with a mounting seat lifting mechanism 6 for driving the mounting seat 3-2-1 to rise and fall, so as to facilitate the adjustment of the height of the mounting seat 3-2-1.

[0042] The mounting seat lifting mechanism 6 includes a driving rod 6-1 rotatably mounted on the top of the frame 1, and a driving motor 6-2 for driving the driving rod 6-1 to operate. Both ends of the driving rod 6-1 are provided with driving gears. Driven gears corresponding to the positions of the two driving gears are rotatably mounted on both sides of the frame 1. The driving gear and the driven gear are driven by a chain. The two sides of the mounting seat 3-2-1 are fixedly connected to the two chains respectively. This embodiment uses a chain drive to drive the mounting seat 3-2-1 to rise and fall, so as to further ensure the stability of the mounting seat 3-2-1 when it is lifted and lowered.

[0043] The unloading driving mechanism 5 includes a driving cylinder 5-1. The fixed bracket 3-2-2 is rotatably mounted on the mounting seat 3-2-1 through the rotating shaft 5-2. A driving arm 5-3 is provided at the bottom of the rotating shaft 5-2. One end of the driving cylinder 5-1 is fixed on the mounting seat 3-2-1, and the other end is hinged to the driving arm 5-3. The driving cylinder 5-1 is used to drive the driving arm 5-3 to operate, which not only has a simpler structure but also has a good driving effect.

[0044] The mounting seat 3-2-1 is provided with a limit block 5-4 for limiting the initial position and the terminal position of the driving arm 5-3. The bottom of the limit block 5-4 is threadedly connected with a limit screw suitable for abutting against the driving arm 5-3 to ensure the stability of the position of the feed nozzle 3-2-3 after switching.

[0045] The collecting box 4-1 has a discharge port 4-1-1 and a discharge port 4-1-2. The discharge port 4-1-1 is connected to a circulation pump, through which the cleaning liquid in the collecting box 4-1 can be discharged back to the customer's circulation cleaning system in time.

[0046] A liquid level meter is provided in the collection box 4-1. The liquid level meter is electrically connected to the circulation pump. When the liquid level in the collection box 4-1 reaches a high level, the circulation pump starts to discharge the cleaning liquid in the collection box 4-1 back to the customer's circulation cleaning system in time. When the liquid level is too low, the customer is reminded to replenish the cleaning liquid in time. In this way, the problem of overflow due to too much cleaning liquid and the problem of equipment running empty due to too little cleaning liquid can be avoided. The signal fed back by the liquid level meter can also be connected to the customer's circulation cleaning system to achieve the linkage between the filling machine cleaning and the customer's circulation cleaning system, thereby improving the automation level of the entire factory.

[0047] The working process of the automatic switching filling machine capable of filling and cleaning at the same time in this embodiment is as follows: the material passes through the feed pipe 3-1-1 of one set of the filling mechanism 3, is divided into several paths by the distribution pipe, reaches the discharge nozzle 3-2-3 through the discharge hose, and is then filled into the packaging material by the discharge nozzle 3-2-3. During the filling, the cleaning liquid can pass through the feed pipe 3-1-1 of another set of the filling mechanism 3, is divided into several paths by the distribution pipe, reaches the discharge nozzle 3-2-3 through the discharge hose, and then is flushed into the cleaning liquid receiving pipe 3-3 by the discharge nozzle 3-2-3, and is collected in the collection box 4-1. The collection box 4-1 has a discharge port 4-1-1 and a discharge port 4-1-2. The discharge port 4-1-1 is connected to a circulation pump, and the discharge port 4-1-1 is connected to the cleaning liquid circulation system at the customer's place; the discharge port 4-1-2 is used as a discharge port to facilitate the emptying of residual liquid. At the same time, a liquid level meter is provided in the collection box 4-1, which can provide real-time feedback on the level of the liquid in the collection box 4-1 and give a signal to the circulation pump and the customer's circulation system. When the liquid level reaches a high level, the circulation pump in the circulation cleaning system starts to discharge the cleaning liquid in the collection box 4-1 back to the customer's circulation cleaning system in time. When the liquid level is too low, the customer is reminded to replenish the cleaning liquid in time, so as to avoid the problem of overflow due to too much cleaning liquid, and to avoid the problem of equipment running empty due to too little cleaning liquid. The signal fed back by the liquid level meter can also be connected to the customer's circulation cleaning system to achieve the linkage between the filling machine cleaning and the customer's circulation cleaning system, and improve the automation level of the entire factory.

[0048] The automatic switching filling machine for the feeding nozzle capable of filling and cleaning at the same time in this embodiment has the following advantages compared with the prior art:

[0049] 1. Improved production efficiency: The feeding nozzle 3-2-3 is driven to rotate by the feeding part driving mechanism 5, so that the feeding nozzle 2-3-2 is switched and seamlessly connected, and the material switching is seamlessly connected, thereby improving production efficiency.

[0050] 2. Improved automation: No need to manually replace the feeding nozzle 2-3-2 and reconnect the feeding pipe, which reduces the labor intensity of the operator.

[0051] 3. Improve the effective operation rate of equipment: Cleaning and disinfection operations can be carried out while filling, which increases the effective operation time of the equipment.

[0052] 4. Improve cleaning cleanliness: Cleaning operation does not take up filling operation time, so the cleaning operation time can be appropriately extended to obtain a relatively high cleanliness.

[0053] 5. Protecting the operator: The filling machine of this embodiment does not require the operator to come into contact with the material and the cleaning liquid during the filling and cleaning and disinfection processes.

[0054] 6. Improve the utilization rate of the internal space of the equipment and reduce the equipment cost: In the past, in order to enable automatic cleaning, the filling machine also needed to be equipped with a cleaning trolley. The filling machine of this embodiment can collect the cleaning liquid into the collection box, so there is no need to equip it with an additional cleaning trolley.

[0055] 7. Reduce the error rate and avoid leakage at the pipe connection: In the past, when replacing the feed nozzle 3-2-3 or changing the material, the pipe needs to be reconnected, which may cause pipe connection errors and leakage at the connection. The filling machine of this embodiment does not need to reconnect the pipe, which fundamentally avoids these problems.

[0056] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
