Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a fully automatic powder filling and capping machine. Background Technology

[0002] A powder filling and capping machine is an automated device for filling and capping powder products. Its main function is to quantitatively fill powder products into containers and seal the containers through a capping device. It is characterized by high efficiency and automation, which can improve the production efficiency and packaging quality of powder products. It is widely used in the filling and sealing processes of powder products in the food, cosmetics and pharmaceutical industries.

[0003] Currently, for powder filling, there are generally three stations: a filling station, a capping station, and a capping station. At the filling station, a screw-driven powder filling mechanism performs the filling. After filling, at the capping station, a manual / automatic cap feeding mechanism places the cap onto the bottle mouth, which then proceeds to the capping station where the capping mechanism tightens the cap. This method, where bottles enter from one side of the machine, are filled, capped, and then exit from the other side, requires a larger space and necessitates a larger work area. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic powder filling and capping machine. It adopts a bottle inlet and outlet method on the same side, has a compact overall structure, realizes the miniaturization design of the equipment, saves space, and has a wider range of applications.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A fully automatic powder filling and capping machine includes a frame, a rotating worktable mounted on the frame, and a bottle infeed conveying section, a powder filling section, a cap hanging section, a capping section, and a bottle outfeed conveying section arranged sequentially along the circumference of the rotating worktable. The bottle infeed conveying section and the bottle outfeed conveying section are arranged parallel to each other on the same side of the frame and are connected to the rotating worktable. The rotating worktable is adapted to sequentially deliver bottles from the bottle infeed conveying section to the powder filling section, the cap hanging section, and the capping section, and then deliver them out by the bottle outfeed conveying section. A first bottle blocking section and a second bottle blocking section are respectively provided directly below the powder filling section and the capping section to allow the bottles to stop at the corresponding worktables.

[0007] Furthermore, the rotating workstation includes an arc-shaped stop composed of an arc-shaped base plate and an arc-shaped top plate that are distributed vertically and fixedly arranged, and a bottle-feeding star wheel plate that rotates around itself. The inner circle of the arc-shaped base plate extends to the bottom of the bottle-feeding star wheel plate, and there is a gap between the inner circle of the arc-shaped top plate and the outer circle of the bottle-feeding star wheel plate, forming a rotating bottle channel with multiple bottle-holding positions evenly distributed along the circumference. The bottle-feeding conveying part and the bottle-outflow conveying part are respectively connected to the inlet and outlet of the rotating bottle channel.

[0008] Furthermore, a motor mounting plate is fixedly installed at the bottom of the frame, and a servo geared motor is fixedly installed on the motor mounting plate.

The bottle inlet star wheel plate is circumferentially adjustable and mounted on the adjustment seat.

[0009] Furthermore, a star wheel pressure plate is provided between the bottle inlet star wheel plate and the adjusting seat. The star wheel pressure plate is provided with a quick locking mechanism and is circumferentially adjustable on the adjusting seat. The bottle inlet star wheel plate is fixedly connected to the star wheel pressure plate through the quick locking mechanism.

[0010] Furthermore, the adjusting seat has multiple arc-shaped through grooves evenly distributed along the circumference, and the area where the star wheel pressure plate overlaps with the arc-shaped grooves is provided with through holes, and the through holes are provided with locking bolts that pass through the arc-shaped grooves and are tightened.

[0011] Furthermore, the inner ring of the bottle inlet star wheel plate is symmetrically provided with notches adapted to the locking mechanism along the circumferential direction. The locking mechanism includes a connecting column fixedly installed on the star wheel pressure plate and a rotating pressure block rotatably installed on the connecting column. The outer ring of the notch is provided with a locking groove corresponding to the rotating pressure block. When the locking pressure block rotates to press against the locking groove, the bottle inlet star wheel plate is connected to the star wheel pressure plate. When the locking pressure block rotates to overlap with the notch, the bottle inlet star wheel plate is separated from the star wheel pressure plate.

[0012] Furthermore, the star wheel pressure plate is provided with a positioning pin, and the bottle inlet star wheel plate is provided with a positioning hole that matches the positioning pin.

[0013] Furthermore, the cap-hanging part includes a cap-feeding channel extending to the bottle mouth of the conveyed bottle body. The end of the cap-feeding channel is inclined, and cap-stopping claws are symmetrically and rotatably installed at the outlet. A spring is connected between the two cap-stopping claws.

[0014] Furthermore, a forward-extending baffle plate is fixedly installed above the outlet of the cover delivery channel.

[0015] Furthermore, the inlet of the bottle conveying unit is provided with a pair of staggered and oppositely arranged bottle-blocking baffles. The bottle-blocking baffles are provided with arc-shaped extensions extending into the conveying channel of the bottle conveying unit, and a channel suitable for the bottle to pass through is formed between the two arc-shaped extensions.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] (1) This utility model changes the structural design of the traditional powder filling and capping machine, and uses a rotating workstation to realize the integrated setting of each processing station. At the same time, the bottle inlet conveying unit and the bottle outlet conveying unit are set on the same side of the frame, which facilitates the planning of the conveying line. The overall structure is compact, realizing the miniaturization design of the equipment, saving space, and having a wider range of applications.

[0018] (2) This utility model, through the cooperation of the bottle inlet star wheel plate and the arc-shaped stop, forms a structure that is suitable for driving the bottle body to move stably along the circumference to each processing station, and has a simple structure.

[0019] (3) This utility model drives the bottle inlet star plate to rotate by a motor and realizes the circumferential adjustment of the bottle inlet star plate by an adjustment seat, which facilitates equipment debugging and enables the bottle inlet conveying section and the bottle outlet conveying section to be properly connected with the bottle clamping position, thereby improving the stability of bottle inlet and bottle outlet.

[0020] (4) This utility model uses a star wheel pressure plate to transition between the adjustment seat and the bottle inlet star wheel plate, and uses a quick locking mechanism to fix the bottle inlet star wheel plate, so as to realize quick disassembly of the bottle inlet star wheel plate and facilitate the replacement of bottle inlet star wheel plates with different specifications to meet the conveying needs of bottles of different specifications.

[0021] (5) The adjustment seat of this utility model realizes circumferential adjustment with the star wheel pressure plate through the arc groove structure. The structure is simple and the adjustment is convenient.

[0024] (8) The cap hanging part of this utility model blocks the bottle cap sent to the outlet by gravity through the cap clamp. Since the two cap clamps are elastically connected, when the bottle passes by, the bottle cap hangs on the bottle mouth, the cap clamp is opened by force, realizes automatic cap delivery, and resets to clamp the next bottle cap.

[0025] (9) The cap part of this utility model is equipped with a baffle plate to prevent the bottle cap from falling off due to jumping, thereby improving the stability of the cap.

[0026] (10) This utility model provides two bottle-blocking baffles at the entrance of the bottle conveying section, which effectively prevents the bottle from tipping over due to inertia when it enters the bottle outlet channel from the rotating workstation, thereby improving the stability of the bottle conveying.

Detailed Implementation

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] (Example 1)

[0036] like Figures 1 to 4 The fully automatic powder filling and capping machine shown includes a frame 1, a rotating worktable 2 mounted on the frame 1, and a bottle infeed conveying section 3, a powder filling section 4, a cap hanging section 5, a capping section 6, and a bottle outfeed conveying section 7 arranged sequentially along the circumference of the rotating worktable 2. The bottle infeed conveying section 3 and the bottle outfeed conveying section 7 are arranged parallel to each other on the same side of the frame 1 and are connected to the rotating worktable 2. The rotating worktable 2 conveys the bottles on the bottle infeed conveying section 3 to the powder filling section 4, the cap hanging section 5, and the capping section 6 in sequence, and finally sends them out from the bottle outfeed conveying section 7. The powder filling section 4 and the capping section 6 are respectively provided with a first bottle blocking section 8 and a second bottle blocking section 9 directly below them. The bottle blocking sections stop the bottles at the corresponding workstations for processing.

[0037] Specifically, in order to improve filling efficiency, two powder filling sections 4 and two capping sections 6 are provided in the frame. The first bottle blocking section 8 and the second bottle blocking section 9 both adopt a cylinder-driven baffle structure to fix the bottle body.

[0038] The rotating worktable 2 includes an arc-shaped stop 2-1, a bottle inlet star wheel plate 2-2, a motor mounting plate 2-3, a servo geared motor 2-4, an adjusting seat, and a star wheel pressure plate 2-5. The arc-shaped stop 2-1 consists of an arc-shaped bottom plate and an arc-shaped top plate that are distributed vertically and fixedly arranged. The bottle inlet star wheel plate 2-2 rotates around itself. The inner circle of the arc-shaped bottom plate extends to the bottom of the bottle inlet star wheel plate 2-2. There is a gap between the inner circle of the arc-shaped top plate and the outer circle of the bottle inlet star wheel plate 2-2, forming a rotating bottle channel with multiple bottle clamping positions evenly distributed along the circumference. The bottle inlet conveying unit 3 and the bottle outlet conveying unit 7 are respectively connected to the inlet and outlet of the rotating bottle channel.

[0039] Specifically, the motor mounting plate 2-3 is fixedly mounted on the frame 1, the servo geared motor 2-4 is fixedly mounted on the frame 1, and the output shaft of the servo geared motor 2-4 is vertically upward. The adjusting seat is coaxially fixed on the output shaft of the servo geared motor 2-4. Multiple arc-shaped through slots are evenly distributed circumferentially on the adjusting seat. The area where the star wheel pressure plate 2-5 overlaps with the arc-shaped slots has through holes. Locking bolts that pass through the arc-shaped slots and are tightened are installed in the through holes, thereby realizing the circumferential adjustment of the adjusting seat and the star wheel pressure plate 2-5. The structure is simple, the adjustment is convenient, and the equipment debugging is easy. This allows the bottle inlet conveyor and bottle outlet conveyor to be precisely aligned with the bottle clamping position, improving the stability of bottle inlet and outlet.

[0040] The star wheel pressure plate 2-5 is equipped with a positioning pin and a quick locking mechanism 2-6. The bottle inlet star wheel plate 2-2 is equipped with a positioning hole 2-2-1 that matches the positioning pin. The inner ring is symmetrically provided with a notch that matches the locking mechanism 2-7. The locking mechanism 2-7 includes a connecting column fixedly installed on the star wheel pressure plate 2-5 and a rotating pressure block rotatably installed on the connecting column. The outer ring of the notch is provided with a locking groove 2-2-2 corresponding to the rotating pressure block. When the locking pressure block rotates to press against the locking groove, the bottle inlet star wheel plate is connected to the star wheel pressure plate. When the locking pressure block rotates to overlap with the notch, the bottle inlet star wheel plate is separated from the star wheel pressure plate, thereby achieving quick locking, convenient disassembly and assembly, and improving the production changeover efficiency when switching specifications.

[0041] The cap-hanging part 5 includes a cap-feeding channel 5-1 extending to the bottle mouth of the conveyed bottle. The end of the cap-feeding channel 5-1 is inclined, and cap-stopping claws 5-2 are symmetrically and rotatably installed at the outlet. A spring 5-3 connects the two cap-stopping claws 5-2. The cap-stopping claws 5-2 stop the bottle caps that are sent to the outlet by gravity. Due to the elastic connection between the two cap-stopping claws 5-2, when the bottle passes by, the bottle cap hangs on the bottle mouth, the cap-stopping claws 5-2 are opened by force, realizing automatic cap feeding, and then resetting to clamp the next bottle cap. In order to prevent the bottle cap from being dragged due to bouncing, a forward-extending cap plate 5-4 is fixedly installed above the outlet of the cap-feeding channel, which plays a good auxiliary role and helps the bottle cap to be better placed on the bottle mouth.

[0042] The inlet of the bottle conveying unit 7 is provided with a pair of staggered and oppositely arranged bottle-blocking baffles 7-1. The bottle-blocking baffles 7-1 are provided with arc-shaped extensions extending into the conveying channel of the bottle conveying unit 7. The two arc-shaped extensions form a channel suitable for the bottle to pass through, effectively preventing the bottle from tipping over due to inertia when it enters the bottle outlet channel from the rotating worktable, and improving the stability of the bottle conveying.

[0043] This utility model changes the structural design of traditional powder filling and capping machines. It uses a rotating worktable 2 to integrate the various processing stations. At the same time, the bottle inlet conveyor and bottle outlet conveyor are set on the same side of the frame, which facilitates the planning of the conveying line. The overall structure is compact, realizing the miniaturization of the equipment, saving space, and making it more widely applicable.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
