[0001] This utility model belongs to the field of filling, and in particular relates to a material weighing and buffering device. Background Technology
[0002] Filling machines are a small category of packaging machines. Based on their filling principle, they can be categorized into atmospheric pressure filling machines, pressure filling machines, liquid filling machines, oil filling machines, paste filling machines, sauce filling machines, granule / slurry filling machines, powder filling machines, large-volume water filling machines, and vacuum filling machines. Atmospheric pressure filling machines fill liquids or solids under atmospheric pressure using their own weight. These machines are further divided into timed filling and volumetric filling types, suitable for filling low-viscosity, non-carbonated liquids such as milk, spirits, mineral water, and fruits. Currently, filling processes often involve conveyor lines transporting bottles to preset positions for single-bottle filling or multiple bottles to a designated position for unified filling. This method cannot achieve continuous filling of multiple rows of bottles, resulting in low filling efficiency. Summary of the Invention

The conveyor line is used to transport multiple bottles being conveyed in a linear fashion. A bottle conveying component is located at one end of the conveyor line. The material dispatching component is located below the material weighing component. The bottle conveying component is used to clamp and transport the bottles one by one to the area below the material dispatching component, and the material dispatching component is used to guide the material flow within the material weighing component to the bottles.
[0006] Furthermore, the material weighing component includes a buffer unit, a weighing unit, and a memory unit, which are arranged sequentially from top to bottom on the support frame. The material falls into the weighing unit through the buffer unit via the feeding component. After the weighing unit weighs the material, it falls into the memory unit. The memory unit is used to distribute the material to the material delivery component. The bottle to be filled is located at the outlet end of the material delivery component. The material enters the bottle to be filled through the material delivery component. Multiple rollers are installed under the support frame, and the support frame can slide relative to each other through the rollers.
[0007] Furthermore, the conveyor line includes several conveyor positions for linearly conveying filled bottles, and each conveyor position corresponds to a bottle conveying assembly. The conveyor positions are used to guide the filled bottles to the bottle conveying assembly or to export the filled bottles from the bottle conveying assembly to the next process.
[0008] Furthermore, each conveyor line position is provided with a discharge plate at its outlet end, and a rotary cylinder is provided at the upper end of the discharge plate. The rotary cylinder is fixedly installed on the first frame. The discharge plate is used to block the passage between the conveyor line position and the bottle conveying assembly.
[0009] Furthermore, the bottle conveying assembly includes multiple bottle claws arranged in parallel to each other, and each bottle claw is mounted on a clamping conveyor line. The clamping conveyor line can open and close each bottle claw, and can drive each bottle claw to move linearly.
[0010] Furthermore, the bottle claw includes two claw bodies, which are symmetrically arranged. Each claw body has an arc-shaped clamping groove on one side, and the outer periphery of the filling bottle is located in the clamping groove. One end of the claw body is fixedly connected to one side of the clamping conveyor body.
[0011] Furthermore, multiple funnels are installed on the clamping and conveying line, and each funnel corresponds to a bottle claw. The funnels are used to guide the material into the filling bottle.
[0012] Furthermore, the material compaction assembly includes a first compression plug, one end of which is fixedly installed to the movable end of a first push rod cylinder. The first push rod cylinder is fixedly installed on a third frame and can push the first compression plug into the funnel or filling bottle.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] like Figures 1-12 As shown, the material weighing and buffering device includes a material weighing component 1, a material dispatching component 2, a conveyor line 3, and a bottle conveying component 4. The material weighing component is slidably mounted on the frame, and the conveyor line 3 is located below the frame. The conveyor line 3 is used to transport multiple bottles 6 in a linear manner, that is, the conveyor line 3 has multiple independently arranged conveyor lines 34, which enables one conveyor line 3 to complete the parallel conveying of multiple bottles 6, improving conveying efficiency and reducing equipment costs. The bottle conveying component 4 is located at one end of the conveyor line 3, and the material dispatching component is located below the material weighing component 1. The bottle conveying component 4 is used to clamp and transport the bottles 6 one by one to the bottom of the material dispatching component, and the material dispatching component is used to guide the material flow in the material weighing component to the bottles 6. This equipment can realize the parallel conveying and filling of multiple bottles 6, which can meet the production capacity requirements, and the equipment cost is low and the filling quality is stable.
[0036] The material weighing component 1 includes a buffer unit, a weighing unit, and a memory unit. The buffer unit, weighing unit, memory unit, and logistics delivery component are arranged sequentially from top to bottom on the support frame 111. The material falls from the feeding component through the buffer unit into the weighing unit. After the weighing unit weighs the material, it falls into the memory unit. The memory unit is used to distribute the material to the logistics delivery component. The bottle to be filled 6 is located at the outlet end of the logistics delivery component. The material enters the bottle to be filled 6 through the logistics delivery component. Multiple rollers 15 are installed below the support frame 11, and the support frame 11 can slide relative to each other through the rollers 15. The buffer unit is used to buffer the material to be filled, and then the material falls into the weighing unit for weighing. The memory unit is a storage device for the material below the logistics delivery component. After the material in multiple memory units is counterweighted, it is uniformly released to the logistics delivery component for filling to meet the filling weight requirements. At the same time, the buffer unit, weighing unit, and memory unit can continuously and quantitatively weigh and fill the material.
[0037] To meet the requirement of counterweight filling in multiple units, the buffer unit includes multiple buffer hoppers 12, the weighing unit includes multiple weighing hoppers 13, and the memory unit includes multiple memory hoppers 14. Each weighing hopper 13 has a buffer hopper 12 and a memory hopper 14 at both ends. The buffer hoppers 12, weighing hoppers 13 and memory hoppers 14 have the same structure and are all funnel-type structures.
[0038] Each of the three hoppers (buffer 12, weighing hopper 13, and memory hopper 14) has a small-mouthed end equipped with an insert plate. Each insert plate has a first linear module installed at one end, which is fixedly mounted on the support frame 11. The insert plate is used to open and close the passage at the small mouth of the hopper to facilitate the conveying of materials in the hopper 12, weighing hopper 13, memory hopper 14, and logistics delivery components. A torque sensor is installed on the first linear module located below the weighing hopper 13. The torque sensor is used to detect the mass of the material in the weighing hopper 13 and transmit it to the controller. In practice, if the two insert plates of the weighing hopper 13 and memory hopper 14 are in the closed state, the corresponding external material conveying device will stop rotating to prevent the hopper 12 from storing too much material and causing the filling line to be obstructed.
[0039] A logistics delivery component is set below the memory unit. The logistics delivery component includes a first belt 21, which is equipped with a drive wheel and a driven wheel. The drive wheel and the driven wheel rotate synchronously through the first belt 21. One end of the drive wheel is connected to the output end of a first motor. The first motor is fixedly installed on the support frame 11. A feeding hopper 22 is set at one end of the first belt 21. The bottle to be filled 6 is located below the feeding hopper 22. The first motor is used to drive the drive wheel and the driven wheel to rotate, thereby realizing the transfer of materials into the bottle to be filled 6.
[0040] To improve filling efficiency, the logistics delivery component includes two opposing first belts 21, and a first belt 21 is respectively arranged on both sides of the discharge hopper 22, and each first belt 21 is inclined. The discharge hopper 22 is located below each first belt 21. Similarly, the logistics delivery component includes two discharge hoppers 22, and the two discharge hoppers 22 are arranged parallel to each other. A discharge swing bucket 23 is arranged on the support frame 11, and the discharge swing bucket 23 is located above each first belt 21. The outlet end of the discharge swing bucket 23 can swing above each discharge hopper 22. The discharge swing bucket 23 is used to distribute materials into one discharge hopper 22.
[0041] The material feeding swing bucket 23 is provided with a first support rod and a second support rod respectively. The support frame 11 is equipped with a second linear module 24. The second linear module 24 is provided with a first baffle 25. The movable end of the second linear module 24 is equipped with a second baffle 26. The first baffle 25 and the second baffle 26 are respectively provided with opening slots 27. The first support rod and the second support rod are respectively located in an opening slot 27. The second linear module 24 can push the second baffle 26 to slide linearly, so that the second support rod moves in an arc along the axis of the first support rod. The opening slot 27 is used for the movement of the second support rod in the vertical direction.
[0042] A photoelectric sensor 28 is installed on the second linear module 24. The photoelectric sensor 28 is used to detect whether there is material in the discharge hopper 22. The photoelectric sensor 28 is existing technology. The photoelectric sensor 28 signal is connected to the controller. When the material enters the discharge hopper 22 via the first belt 21, the photoelectric sensor 28 can detect the presence of the material and transmit the signal to the controller so that the controller can record the completion of filling.
[0043] The conveyor line 3 includes a first transmission line 31 and a second transmission line 32. The first transmission line 31 is mounted on a first frame, and the second transmission line 32 is mounted on a second frame. The first transmission line 31 and the second transmission line 32 are arranged parallel to each other. A third frame 33 is arranged between the first frame and the second frame. A bottle conveying assembly 4 is mounted on the third frame 33. The first transmission line 31 has a plurality of conveyor positions 34 for linearly conveying filled bottles 6. Each conveyor position 34 corresponds to a bottle conveying assembly 4, and the conveyor position 34 is used to convey the filled bottles 6. The bottle conveying assembly 4 clamps and positions the bottles, guiding them to the second transmission line 32. The second transmission line 32 guides the filled bottles 6 to the next process. The first transmission line 31 provides the bottles 6 to be filled to the bottle conveying assembly 4. After being positioned, clamped, and conveyed by the bottle conveying assembly 4, the bottles are transported to the bottom of the logistics delivery assembly. After the bottles 6 are filled, they are transported to the second transmission line 32 and guided to external equipment. This automated process completes the filling of the bottles 6, reducing manpower consumption, lowering production costs, and ensuring stable filling quality.
[0044] Several dividing plates 35 are installed on the first frame. Each dividing plate 35 is located above the first transmission line 31. The dividing plate 35 is used to divide the first transmission line 31 into several conveying positions 34. The lower end of the dividing plate 35 does not contact the first transmission line 31. The dividing plate 35 is only used to limit the position of the filling bottle 6 and does not interfere with the first transmission line 31 to convey the filling bottle 6. The installation structure is simple and easy to implement. Each conveying position 34 has a first guide plate 36 at its outlet end. The first guide plate 36 has an arc-shaped structure. The first guide plate 36 is used to guide the filling bottle 6 from the conveying position 34 to the bottle conveying assembly 4 to ensure the stability of the initial position of the filling bottle 6 entering the bottle conveying assembly 4.
[0045] A limiting rod 37 is installed on the first frame. The limiting rod 37 is located above the first transmission line 31 and is higher than the upper end of the filling bottle 6. The first limiting rod 37 is a limiting structure for the height of the filling bottle 6, preventing the stacked filling bottles 6 from flowing into the bottle conveying assembly 4, and ensuring the quality and stability of the filling process.
[0046] The two ends of the limiting rod 37 are installed on the first frame through the support plate 38. The support plate 38 is provided with an elliptical elongated hole. The outer periphery of the limiting rod 37 can slide within the elliptical elongated hole. The limiting rod 37 is fixed to the support plate 38 by a locking nut. By sliding the limiting rod 37 within the elliptical elongated hole, the relative height of the limiting rod 37 on the first transmission line 31 can be adjusted to meet the use of different specifications of filling bottles 6 and improve the applicability of the device.
[0047] Each conveyor line 34 has a discharge plate 39 at its outlet end, and a rotary cylinder 310 is installed on the upper end of the discharge plate 39. The rotary cylinder 310 is fixedly installed on the first frame. The discharge plate 39 is used to block the passage between the conveyor line 34 and the bottle conveying assembly 4. The discharge plate 39 is an opening and closing structure for each conveying limit outlet end to prevent the filled bottles 6 from accumulating at the inlet end of the bottle conveying assembly 4. Through the cooperation of the discharge plate 39 and the first transmission line 31, it is possible to discharge each filled bottle 6 on each conveyor line 34 individually, and to center the position of the filled bottle 6 on the first transmission line 31 to ensure the stability of the position of the filled bottle 6 when it enters the bottle conveying assembly 4. In order to reduce the size of the discharge plate 39 and improve the compatibility between the discharge plate 39 and the filled bottle 6, the cross-section of the discharge plate 39 is an arc structure, and the width is smaller than the width of the conveying limit, and the inner arc is larger than the outer arc of the filled bottle 6.
[0048] To ensure that the filled bottle 6 enters the second transmission line 32 stably after filling, a second guide plate 311 is installed on the second frame. The second guide plate 311 has an arc-shaped structure and is used to guide the filled bottle 6 from the bottle conveying assembly 4 to the second transmission line 32.
[0049] In this embodiment, the first transmission line 31 and the second transmission line 32 have the same structure. The first transmission line 31 includes a first motor, which is fixedly mounted on a first frame. The conveying end of the first motor is equipped with an active roller, which is rotatably connected to the first frame. A driven roller is rotatably sleeved on the first frame. The outer periphery of the driven roller and the outer periphery of the active roller are connected by a belt to form a synchronous transmission structure. The filling bottle 6 is placed on the belt. The first motor can drive the driven roller to rotate through the active roller, thereby realizing that the belt drives the filling bottle 6 to move. When the filling bottle 6 is blocked by the feeding plate 39, the bottom of the filling bottle 6 slides relative to the surface of the belt.
[0050] The bottle conveying assembly 4 includes multiple bottle claws 41 arranged in parallel to each other, and each bottle claw 41 is mounted on the clamping conveyor line 3. The clamping conveyor line 3 is mounted on the third frame 33 via the fourth frame 42. The first transmission line 31 and the second transmission line 32 are located at the two ends of the clamping conveyor line 3, respectively. The bottle claws 41 are used to clamp the periphery of the filling bottle 6, and each bottle claw 41 is individually mounted on the clamping conveyor line 3. The clamping conveyor line 3 enables the assembly line clamping operation of the filling bottle 6, resulting in low maintenance costs and high production efficiency.
[0051] The clamping conveyor line 3 includes a second motor 43, which is fixedly mounted on a fourth frame 42. A first sprocket and a second sprocket are rotatably connected to the fourth frame 42. The first sprocket and the second sprocket are synchronously driven by a first chain. The drive shaft of the second motor 43 is fixedly mounted on the first sprocket. The clamping conveyor line 3 uses the first chain to convey the bottle claw 41, ensuring the stability of the bottle claw 41 installation. The bottle claw 41 is mounted on the chain link of the first material bar, and the installation structure is stable.
[0052] The bottle claw 41 includes two claw bodies 411, which are symmetrically arranged. Each claw body 411 is mounted on a chain link. Each claw body 411 has an arc-shaped clamping groove 412 on one side. The periphery of the filling bottle 6 is located within the clamping groove 412. One end of the claw body 411 is fixedly connected to one side of the first chain, such as... Figure 7 As shown, during implementation, the first chain is provided with a first arc-shaped segment 44, a first straight segment 45, a second arc-shaped segment 46, and a second straight segment connected end to end around the fourth frame 42. The bottle claws 41 on the first arc-shaped segment 44 are used to align the outer periphery of the filling bottle 6. The bottle claws 41 on the first straight segment 45 are used to clamp the filling bottle 6. The bottle claws 41 on the second arc-shaped segment 46 are used to release the filling bottle 6. The bottle claws 41 on the second straight segment are in a ready-to-clamp state. The first arc-shaped segment 44 is located at the discharge end of the first transmission line 31, the second arc-shaped segment 46 is located at the feed end of the second transmission line 32, and the first straight segment 45 and the second straight segment are located on the third frame 33. As the two symmetrical claws 411 move from the second straight segment to the first arc segment 44, influenced by the arc trajectory of the first arc segment 44, the two claws 411 open relative to each other. As the two claws 411 move, the filling bottle 6 gradually enters between the two claws 411. When the two claws 411 gradually move from the first arc segment 44 to the first straight segment 45, the two claws 411 gradually close, and the filling bottle 6 is clamped by the bottle claws 41, thus completing the clamping and positioning of the filling bottle 6. After the filling is completed, when the filling bottle 6 moves from the first straight segment 45 to the second arc segment 46, the two claws 411 gradually open and release the filling bottle 6 onto the second transmission line 32.
[0053] The fourth frame 42 is provided with multiple sliding holes, and a tensioning shaft 47 is slidably connected in each sliding hole. One end of each tensioning shaft 47 is fixedly connected to the periphery of the first central shaft. The first central shaft and the periphery of the first central shaft are rotatably connected to the second sprocket. The first tensioning shaft 47 is fixed to the fourth frame 42 by a tightening nut. The tensioning shaft 47 is a tensioning structure for the first chain and the second chain 48 described below, so as to ensure the stability of the power of the first chain and the second chain 48.
[0054] One end of the first central shaft is rotatably connected to the third sprocket, and the fourth sprocket is rotatably connected to the fourth frame 42. The periphery of the third sprocket and the fourth sprocket form a synchronous transmission structure through the second chain 48. Multiple funnels 49 are installed on the second chain 48, and each funnel 49 corresponds to a bottle claw 41. The funnels 49 are used to guide the material into the filling bottle 6. A funnel 49 is concentrically arranged above each bottle claw 41. The large diameter end of the funnel 49 faces the outlet end of the logistics delivery component, and the small diameter end of the funnel 49 faces the inlet end of the filling bottle 6 to prevent material leakage during filling.
[0055] A material compaction component 5 is provided on the bottle conveying assembly 4. The material compaction component 5 includes a first pressing plug 51. One end of the first pressing plug 51 is fixedly installed to the movable end of the first push rod cylinder 52. The first push rod cylinder 52 is fixedly installed on the third frame 33. The first push rod cylinder 52 can push the first pressing plug 51 to be inserted into the funnel 49 or the filling bottle 6. The first pressing plug 51 is located downstream of the logistics delivery assembly. When filling the filling bottle 6, the bottle conveying assembly 4 will pause for a preset time. During the pause, the first push rod cylinder 52 will drive the first pressing plug 51 to move down, ensuring that all the material in the funnel 49 enters the filling bottle 6, preventing leakage or blockage in the funnel 49, and ensuring stable filling.
[0056] The material compaction assembly 5 also includes a second compaction plug 53. One end of the second compaction plug 53 is fixedly installed to the movable end of the second push rod cylinder 54. The second push rod cylinder 54 is fixedly installed on the third frame 33. The second push rod cylinder 54 can push the second compaction plug 53 into the funnel 49. The first compaction plug 51 and the second compaction plug 53 are arranged sequentially along the travel direction of the filling bottle body 6. The outer diameter of the second compaction plug 53 is smaller than the outer diameter of the first compaction plug 51. The outer diameter of the second compaction plug 53 is smaller than the inner diameter of the large diameter end of the funnel 49. The outer diameter of the first compaction plug 51 is smaller than the inner diameter of the small diameter end of the funnel 49. The second compaction plug 53 is a segmented compaction structure of the first compaction plug 51, which improves the quality and efficiency of the drainage of the funnel 49.
