Description

Technical Field

[0001] This utility model relates to the field of automatic filling equipment technology, and in particular to a quick-change filling and feeding section and a filling machine. Background Technology

[0002] In the liquid filling industry, to meet market demands and balance economic efficiency, a single filling machine typically needs to accommodate various bottle sizes to meet the needs of small-batch production of multiple specifications. For bottle sizes of different heights, automatic adjustment of the nozzle height is generally achieved. However, for bottle sizes with different lateral dimensions, the spacing between adjacent bottles varies. The current mainstream adjustment methods are generally as follows:

[0003] The first method involves manually disassembling and assembling the feeding nozzles, adjusting the spacing between adjacent feeding nozzles, and simultaneously adjusting the spacing of the bottle mouth clamps corresponding to each feeding nozzle to meet the filling requirements of bottles of different sizes. This adjustment method is time-consuming and labor-intensive, especially when there are a large number of feeding nozzles, resulting in long production changeover times.

[0004] The second method is to keep the distance between the dispensing nozzles constant and adjust the distance between the bottles by adding splicing brackets so that they correspond one-to-one with the dispensing nozzles. This adjustment method increases the distance between adjacent bottles, which will inevitably sacrifice some conveying efficiency and affect the overall filling capacity.

[0005] Therefore, it is necessary to optimize the structure of the existing filling and feeding section. Utility Model Content

[0037] like Figures 1 to 5 The filling machine shown includes a frame 1, a material bin 2 located at the top of the frame 1, and a filling section 3, a conveying section 4, and a discharging section located within the frame 1. The discharging section includes a pitch-changing module 5 and multiple discharging components 6 arranged along the length of the pitch-changing module 5. Each discharging component 6 includes a mounting base 6-1, a discharging nozzle 6-2, and a bottle neck clamp 6-3. The filling section 3 has an inlet connected to the material bin 2 and multiple outlets corresponding to and connected to the discharging nozzles 6-2. The conveying section 4 is located below the discharging section and extends horizontally through the frame 1, used to convey bottles to be filled. Mounting base 6-1 is fixedly mounted on the corresponding movable module of the pitch-changing module 5, enabling rapid pitch adjustment under the drive of the pitch-changing module 5. The discharge nozzle 6-2 is vertically mounted on mounting base 6-1 and is used to insert into the corresponding bottle below for automatic filling. A pair of bottle neck clamps 6-3 are provided, positioned on either side of the lower end of the discharge nozzle 6-2, and are horizontally openable and closable on mounting base 6-1. These clamps are used to clamp the bottle neck during filling, preventing the bottle from tipping over. By mounting the bottle neck clamps 6-3 and the discharge nozzle 6-2 on the same mounting base 6-1, and moving synchronously with the movable module of the pitch-changing module 5, rapid adjustment is truly achieved, improving changeover efficiency and ensuring overall filling capacity.

[0038] Specifically, a screw jack 7 driven by a motor is fixedly installed at the bottom of the frame 1. A lifting plate 8 is fixedly installed at the top of the movable end of the screw jack 7. The variable pitch module 8 is a module with an equally spaced variable structure, which is installed on the lifting plate 8 to realize the lifting and adjustment of the entire feeding section and meet the filling needs of bottles of different heights.

[0039] A base plate 9 is fixedly mounted in the middle of the frame 1, and a base frame 10 is fixedly mounted on the base plate 9. A handwheel screw adjustment assembly 11 is provided on the base frame 10, extending through the conveying section 4 perpendicular to the bottle conveying direction. Guide rod assemblies 12 are arranged parallel to both sides of the handwheel screw adjustment assembly 11, and a cleaning tank 13 is fixedly connected to the moving nut of the handwheel screw adjustment assembly 11. The bottom of the cleaning tank 13 is located between the conveying plane of the conveying section 4 and the unloading section, and is fixedly connected to the moving blocks of the two guide rod assemblies 12. This allows the cleaning tank 13 to move smoothly when the handwheel is turned, and during production changes, it can be moved directly to below the unloading section, facilitating the placement of the unloading nozzle 6-2 into the cleaning tank 13 for cleaning.

[0040] The conveying section 4 has adjustable guardrails 14 on both sides and bottle-stopping assemblies 15 at both ends that are adjustable along the bottle conveying direction to meet the limiting conveying requirements of bottles of different sizes. Specifically, the conveying section 4 has multiple connecting seats 16 along its length on both sides. Each connecting seat 16 has a column 17 with a through hole. An adjusting rod 18 is inserted into the through hole. One end of the adjusting rod 18 is fixed to the guardrail 14 on the same side, and the other end has a limiting pin. The top of the column 17 has a locking screw 19, which is radially arranged along the adjusting rod 18 and abuts against the adjusting rod 18. By loosening the locking screw 19, the spacing of the guardrails 14 can be quickly adjusted. Guide rods 20 extending along the bottle conveying direction are fixedly installed at both ends of the side of the conveying section 4. Clamping blocks 21 are fixedly installed on the guide rods 20 by screws. Bottle-stopping assemblies 15 are fixed to the clamping blocks, and the bottle-stopping assemblies 15 can be moved by loosening the screws. The area where the guardrail on the side near the cleaning tank 13 overlaps with the cleaning tank 13 has a notch to allow passage through the cleaning tank. In non-cleaning mode, the side wall of the cleaning tank 13 can be used as a guardrail to prevent bottles from falling. The structure is compact and easy to use.

[0041] Mounting base 6-1 includes a first mounting plate 6-1-1 and a second mounting plate 6-1-2 that are vertically fixed together. The first mounting plate 6-1-1 is fixedly mounted on the movable module of the variable pitch module 5. A lifting cylinder 6-4 is fixedly mounted on the top of the second mounting plate 6-1-2. The piston rod of the lifting cylinder 6-4 is set vertically upward and fixedly connected to a third mounting plate 6-5. The discharge nozzle 6-2 is fixedly mounted on the third mounting plate 6-5. A double-clamp cylinder 6-6 is fixedly mounted on the bottom of the second mounting plate 6-1-2. The two piston ends of the double-clamp cylinder 6-6 are horizontally positioned and respectively fixed to L-shaped connecting plates 6-7. The bottom of the connecting plate 6-7 has a downward-facing slot, and the side has a limiting screw 6-8. The bottle neck clamp 6-3 is inserted into the corresponding slot with a gap. The end of the limiting screw 6-8 abuts against the side wall of the bottle neck clamp. By loosening the limiting screw 6-8, the bottle neck clamp 6-3 can be adjusted horizontally onto the connecting plate 6-7, thereby adjusting the clamping distance between the two bottle neck clamps to meet the clamping requirements of different bottle neck sizes, offering better versatility. The surface of the bottle neck clamp 6-3 has graduations for quick adjustment during production changes. A lifting cylinder 6-4 drives the discharge nozzle 6-2 to be raised and lowered onto the mounting base. Simultaneously, the double-clamp cylinder 6-6 moves the two bottle neck clamps closer and further apart, resulting in a simple structure and rapid response.

[0042] This utility model uses a variable pitch module 5 to adjust the spacing of the arranged feeding components 6, eliminating the need for manual disassembly and assembly. At the same time, the structure of the feeding components 6 is optimized by placing the bottle mouth clamp 6-3 for clamping the bottle mouth and the feeding nozzle 6-2 for filling on the same mounting base 6-1, which moves synchronously with the movable module of the variable pitch module 6, truly achieving rapid adjustment, improving production changeover efficiency, and ensuring overall filling capacity.
