Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically a traditional Chinese medicine rehabilitation exercise device. Background Technology

[0002] In the production of topical preparations (such as ointments, creams, gels, eye drops, ear drops, etc.), filling and capping are crucial post-packaging processes. Traditional production processes generally use filling machines and capping machines as two separate pieces of equipment, connected by a conveyor belt to form a production line. This separate operation mode has gradually revealed several prominent technical bottlenecks in long-term practice: Large footprint: Independent single equipment requires its own foundation support and operating space, the entire production line is long and the layout is loose, resulting in low utilization of workshop space; In terms of filling: the quantitative accuracy and liquid level control of traditional filling machines are easily affected by human factors (such as operator rhythm) or mechanical fluctuations, resulting in deviations in the filling volume of a single bottle; Regarding the screw cap: The tightness of the screw cap depends entirely on the worker's feel or simple mechanical adjustment, and the torque cannot be controlled. This can easily lead to the screw cap being too tight and damaging the bottle cap threads, or the screw cap being too loose and not sealing properly, affecting the product's shelf life and user experience.

[0003] Therefore, a filling and capping machine for external preparations is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing equipment layout is scattered, resulting in low workshop space utilization and the product is easily contaminated by manual capping.

[0005] To address the aforementioned technical problems, a filling and capping integrated machine for external preparations is proposed. This is achieved through the following technical solution: A filling and capping integrated machine for external preparations includes a support frame, a filling component, a cap placement and pressing component, a capping component, and a conveying component. The support frame is placed on the ground, and the filling component is fixed to the support frame, primarily for filling the bottles with medication. The bottles are conveyed to the various parts for assembly via the conveying component. The cap placement and pressing component is fixed to the support frame, placing and pressing the cap at the bottle opening. The capping component screws the cap onto the bottle opening, ensuring the cap is securely attached.

[0006] In a preferred embodiment of the present invention, the filling assembly includes a first cylinder, a lifting frame, a filling head, and a support rod. The support rod is fixed on the support frame, and the first cylinder is mounted on the support rod. The first cylinder is connected to the lifting frame and drives the lifting frame to move up and down. The filling head is mounted on the lifting frame. Driven by the cylinder, the filling head can be raised and lowered quickly and smoothly, ensuring that the filling head can be accurately inserted into the bottle mouth and maintain a suitable height to prevent liquid splashing or dripping.

[0007] In a preferred embodiment of the present invention, the cap feeding and pressing assembly includes a mounting frame, a second cylinder, a cap storage tube, and a pressure plate. The mounting frame is fixed on a support frame, one end of the second cylinder is fixed on the mounting frame, and the other end is fixed to the pressure plate. One end of the pressure plate is fixed to the cap storage tube, thereby realizing automatic cap feeding and initial pressing of the caps, creating the necessary conditions for subsequent capping and improving the continuity of the capping process.

[0008] In a preferred embodiment of the present invention, a capping assembly is further provided on the mounting frame. The capping assembly includes a first motor and a capping head. The first motor is mounted on the mounting frame and is fixedly connected to the capping head. By integrating the capping assembly onto the mounting frame of the capping and pressing assembly, the equipment layout becomes more compact and reasonable, reducing independent support structures and saving costs and production space.

[0009] In a preferred embodiment of the present invention, the conveying assembly includes a second motor, a conveyor belt structure, a fixed plate, a turntable, a small support column, and a pallet. The second motor is mounted on the conveyor belt structure, fixed plates are mounted on both sides of the conveyor belt structure, a pallet is fixed at one end of the conveyor belt structure, a small support column is fixed at the bottom of the pallet, the small support column is fixed on a support frame, and the turntable is mounted on a mounting frame. Through the combination of the conveyor belt and the turntable, the bottles are automatically and smoothly transferred between different workstations, forming a continuous production line.

[0010] In a preferred embodiment of the present invention, the conveyor belt structure consists of two parts: a material conveying structure and a material discharging structure. The material discharging structure is equipped with a suction cup for absorbing the bottle, thus dividing the conveying process into two parts: "material conveying" and "material discharging," making the material flow direction clear and easy to control.

[0011] In a preferred embodiment of the present invention, a third motor is provided at the bottom of the mounting frame. The third motor controls the turntable to move the bottle to the lower component, providing power to the turntable on the mounting frame.

[0012] In a preferred embodiment of the present invention, the filling head is provided with a feed inlet, which is connected to a feed pipe, and the feed pipe is connected to an external storage tank to achieve a continuous supply of liquid medicine.

[0013] The advantages of this utility model compared with the prior art are: Compact structure and flexible layout: It integrates the four originally separate processes of filling, capping, pressing, and screwing on the cap into one machine, realizing "one-stop" processing from empty bottle to finished product; High space utilization: By integrating functions such as the capping assembly onto the mounting frame, the equipment has a compact structure and a small footprint, saving valuable space in the production workshop; Adaptable to different bottle sizes: The filling, capping, and screw capping components are relatively independent, making it easy to quickly adjust and replace them for different bottle and cap types (such as replacing filling heads and capping heads of different sizes), thus enhancing the equipment's versatility and flexibility. Non-destructive feeding: The discharge end uses a suction cup to pick up the bottle, avoiding scratches or squeezing deformation that mechanical grippers may cause to the bottle body (especially finished products with labels), thus protecting the product appearance; Automated operations reduce direct contact between people and materials during the production process, thus lowering the risk of contamination from microorganisms, dust, and other contaminants.

[0022] The support frame 1 is mainly composed of a rectangular panel and rectangular support legs, on which the filling component 2, capping and pressing component 3, capping component 4 and conveying component 5 are fixed.

[0023] Definition: In this embodiment, with the ground as the reference point, the support frame 1 is placed on the ground. The direction perpendicular to the ground and upward is called "up," and the corresponding direction perpendicular to the ground and downward is called "down."

[0024] like Figure 4 As shown, the filling assembly 2 includes a first cylinder 21, a lifting frame 22, a filling head 23, and a support rod 24. The support rod 24 is welded to the panel of the support frame 1. The first cylinder 21 is fixed to the top of the support rod 24. The first cylinder 21 is fixedly connected to the lifting frame 22.

One end of the pressure plate 34 is fixed to the cap storage tube 33.

[0029] The mounting frame 31 consists of two rectangular plates and a support column. The four corners of the two rectangular plates are connected by a second cylinder 21. Each plate has three holes. The support column passes through the middle hole and is fixed to the support frame 1. The other two holes are connected to the cap-pressing assembly 3 and the cap-screwing assembly 4, respectively. The second cylinder 32 is preferably a cylinder in the prior art.

[0030] The mounting bracket 31 has a cap-pressing assembly 3 and a cap-screwing assembly 4 fixed on its two sides, respectively.

[0031] The pressure plate 34 is a plate with a "Z" shaped cross-section. A bottle cap storage tube 33 is fixed to the higher end of the pressure plate 34. Multiple bottle caps are placed at an angle inside the bottle cap storage tube 33. A hole is opened at the junction of the pressure plate 34 and the bottle cap storage tube 33. A sensing rotating head 37 is inside the hole. A sensor 38 is fixed near the bottom of the pressure plate 34 near the sensing rotating head 37. When a bottle is sensed to arrive, the sensing rotating head 37 opens, and the bottle cap in the bottle cap storage tube 33 falls to the bottle mouth.

[0032] The capping assembly 4 is located at the lower end of the mounting bracket 31. The capping assembly 4 includes a first motor 41 and a capping head 42. The first motor 41 is fixed to the top of the mounting bracket 31 and is connected to the capping head 42. The capping head 42 is preferably a capping head structure in the prior art.

[0033] Near the support frame 1, the support column of the mounting bracket 31 has a turntable 59 fixed on it. The turntable 59 is a disc with a serrated outer side and a hole in the middle. A rotating bushing 510 is fixed in the hole. The rotating bushing 510 is screwed onto the support column of the mounting bracket 31. There are two turntables 59 in total. The two turntables 59 are parallel and about 5-8 cm apart. The serrated outer side is mainly for conveying the bottle during the capping process.

[0034] like Figure 6 and 7 As shown, the conveying assembly 5 includes a second motor 53, a conveyor belt structure 54, a fixing plate 55, a turntable 56, a small support column 57, and a pallet 58. The second motor 53 is fixed on the conveyor belt structure 54. The fixing plates 55 are welded to both sides of the conveyor belt structure 54. The pallet 58 is fixed to one end of the conveyor belt structure 54. The small support column 57 is fixed to the bottom end of the pallet 58. The small support column 57 is fixed on the support frame 1. The turntable 56 is fixed on the support column of the mounting frame 31.

[0035] A support plate 58 is fixed at the bottom of the bottle, 2-4 cm away from the bottom turntable 56. The support plate 58 is a ring and its diameter is slightly larger than that of the turntable 56.

[0036] A small support column 57 is fixed between the bottom of the tray 58 and the support frame 1. The small support column 57 is cylindrical, and the diameter of the bottom near the support frame 1 is slightly larger than that of the upper cylinder. A fixing block 511 is fixed at the top of the small support column 57, and a baffle ring support column 512 is fixed on the fixing block 511.

[0037] The baffle ring support 512 is much shorter than the small support 57. A baffle ring 513 is fixed on the baffle ring support 512 to prevent the bottle from falling.

[0038] There are two conveyor belt structures 54, namely a material conveying structure 51 and a material discharging structure 52. Both conveyor belt structures 54 are preferably the conveyor belt structures in the prior art. The material discharging structure 52 is fixed with a suction cup 59 for picking up the bottle.

[0039] like Figure 7 As shown, suction cup 59 is connected to third cylinder 514, third cylinder 514 is fixedly connected to mounting plate 515, mounting plate 515 is fixedly connected to discharge structure 52, mounting plate 515 is shaped like "7", one side is fixed to discharge structure 52, and the other side is fixed to third cylinder 514, which can transport bottles with screw caps out.

[0040] The process of using this device: Feeding: Empty bottles are placed sequentially on the conveyor belt of the feeding structure 51, while a large number of bottle caps are stacked into the bottle cap storage tube 33.

[0041] Filling: The empty bottle moves forward with the conveyor belt. When it passes under the filling head 23, the first cylinder 21 is activated, pushing the lifting frame 22 to move downward, so that the filling head 23 descends and approaches the bottle mouth. The external feeding system (shown in the figure) supplies the medicine to the filling head 23 through the feed port 25, and the medicine is quantitatively injected into the bottle.

[0042] After filling is completed, the first cylinder 21 resets, driving the filling head 23 to rise and leave the bottle mouth.

[0043] The filled bottles are transported to the capping and sealing assembly 3.

[0044] Capping and capping: The turntable 56 rotates, sending the bottle filled with medicine directly below the capping and capping assembly 3. The second cylinder 32 is activated, pushing the pressure plate 34 and the bottle cap storage tube 33 downward as a whole. The bottom bottle cap of the bottle cap storage tube 33 is put on the bottle mouth. Then, the pressure plate 34 presses down on the top of the bottle cap, applying a downward pressure to make the bottle cap and the bottle mouth initially fit together, preparing for subsequent capping. The second cylinder 32 drives the pressure plate and the bottle cap storage tube to rise and reset.

[0045] Turntable 56 continues to rotate, sending the pre-capped bottle directly below capping head 42. First motor 41 starts, driving capping head 42 to rotate. As second cylinder 21 drives mounting bracket 31 to descend, capping head 42 moves downward to clamp the bottle cap. Under the combined action of rotation and downward pressure, the bottle cap is tightened on the bottle mouth. After capping is completed, capping head 42 stops rotating and rises to reset together with capping assembly 3.

[0046] The turntable 56 rotates for the last time, transferring the finished bottle to the interface of the discharge structure 52. The suction cup 59, under pneumatic action, picks up the finished bottle and places it smoothly onto the conveyor belt of the discharge structure 52.

[0047] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
