Description

Technical Field

[0001] This invention relates to the field of sterilization equipment technology, and specifically to a multifunctional sterilization device for oral liquids. Background Technology

[0002] Danshen oral liquid is a traditional Chinese medicine, mainly composed of the Chinese medicinal herb Danshen, which has the effects of promoting blood circulation, removing blood stasis, nourishing the heart, and unblocking the meridians. It is primarily used to treat symptoms such as chest pain, chest tightness, and stabbing pain caused by qi stagnation and blood stasis, and is especially suitable for patients with angina pectoris due to coronary heart disease. The medicine is a brownish-red transparent liquid with a slightly sweet and slightly bitter taste. After production and preparation, Danshen oral liquid requires bottling to inject the liquid into bottles for convenient storage and transportation. To ensure the hygiene and safety of the oral liquid during production, the bottles are sterilized before bottling to ensure cleanliness and prevent any impact on the safety of the oral liquid for consumption.

[0003] Currently, most oral liquids are sterilized using tank-shaped autoclaves after bottling. After bottling, trolleys and racks are used to place the prepared oral liquids into the autoclave, where steam sterilization is performed. However, when using the autoclave, the oral liquids are neatly arranged on the trolley racks, resulting in them being too close together. This prevents the bottles from being fully sterilized by steam and causes uneven heating, posing a risk of bottle breakage. If they are placed separately, the oral liquids may tip over, causing bottle breakage and affecting the sterilization effect. Furthermore, the autoclaves need to be manually removed from the production line, impacting production efficiency and reducing economic benefits. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in which the sterilization of the outer side of the bottle after the oral liquid is filled is low and the sterilization is incomplete, and to provide a multifunctional sterilization device for oral liquids.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a multifunctional sterilization device for oral liquids, comprising a receiving tray disposed at the tail of a filling machine, wherein the output end of the receiving tray is provided with a variable-pitch auger for adjusting the distance between adjacent oral liquid bodies, the output end of the variable-pitch auger is provided with a first conveying component capable of adjusting the relative distance, the output end of the first conveying component is provided with a sterilization chamber, the sterilization chamber is provided with a conveying device for picking up oral liquid bodies one by one, the sterilization chamber includes a chamber body, and a spraying device is disposed inside the chamber body along the conveying path of the conveying device.

[0006] Furthermore, the first conveying component consists of two oppositely arranged conveyor belts, and the bottom of each conveyor belt is provided with a sliding plate along the conveying direction for sliding connection with the bottom of the oral liquid body. The length of the sliding plate is less than the length of the conveyor belt.

[0007] Furthermore, an electric push rod that outputs vertically downwards is provided above the conveyor belt. The output end of the electric push rod is provided with a mounting frame. The bottom surface of the mounting frame is provided with a roller assembly for pressing down the oral liquid body. The gap of the roller assembly is smaller than the diameter of the top of the oral liquid body.

[0008] Furthermore, the spraying device includes a steam pipe installed on the side wall of the housing, a nozzle facing the center is installed on the side wall of the steam pipe, and a regulating valve for adjusting the flow rate of the steam pipe is installed on the outer wall of the housing.

[0009] Furthermore, the steam pipes are arranged in two sets opposite each other.

[0010] Furthermore, an exhaust fan is provided on the top of the enclosure, and a drain pipe is provided at the bottom of the enclosure.

[0011] Furthermore, the conveying device includes sprockets disposed on the inner wall of the box, and multiple sets of sprockets are provided. A chain for conveying the oral liquid body is disposed between the sprockets, and the chain is arranged in a loop inside the box.

[0012] Furthermore, a connecting rod is fixedly provided on the side of the chain, and a gripping device for connecting the oral liquid body is provided at the other end of the connecting rod. The gripping device includes a functional can connected to the connecting rod, the end of the connecting rod is rotatably connected to the side wall of the functional can, and a suction cup for connecting the bottom of the oral liquid body is provided on the top of the functional can.

[0013] Furthermore, an upper piston is provided at the upper part of the functional tank, a movable block is provided at the upper part of the upper piston, a vacuum chamber for accommodating the movable block is provided at the bottom of the suction cup, a lower piston is provided at the lower part of the functional tank, hydraulic oil is filled between the upper piston and the lower piston, and a driving device is connected to the bottom of the lower piston.

[0014] Furthermore, the driving device includes a driving rod connected to the lower piston, a connecting ring at the bottom of the driving rod, the connecting ring being connected to a track on the inner wall of the box, the track being cyclically arranged along the rotation direction of the chain, a chute with the same direction being provided above the track, and a roller in rolling connection with the chute being provided at the lower part of the functional tank, the distance between the track and the chute changing according to the loading, unloading and sterilization process.

[0015] The beneficial effects of this invention are as follows: the distance between the two conveyor belts can be adjusted by the bottom adjustment plate, making the entire production line suitable for various types of oral liquids. The adjustment is simple and convenient. The chain ensures the conveying direction, and the distance between the track and the chute controls the adsorption and release, allowing the suction cup to connect to the bottom of the oral liquid body. This exposes most of the oral liquid body inside the chamber, increasing the contact area with steam during sterilization. Compared to existing methods where the oral liquid bodies are close together during sterilization, this method results in a larger sterilization area, greater gaps between the oral liquid bodies, and better steam envelopment, leading to more comprehensive sterilization, more uniform heating, reduced bottle breakage, improved production efficiency and sterilization effect, and ensured hygiene and safety during production.

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] See Figures 1 to 9 This invention discloses a multifunctional sterilization device for oral liquids, including a receiving tray 2 installed at the tail of a filling machine. The filled oral liquids are collected on the receiving tray 2. The receiving tray 2 is designed to be inclined or to be slowly conveyed forward by a conveyor belt 202, so that the oral liquid bottles can enter the auger for subsequent processing. The receiving tray 2 forms a space for temporarily storing the oral liquid body 4, and the material is gradually supplied according to the sterilization rate.

[0028] At the output end on the side of the receiving tray 2, a variable pitch auger 201 is installed. The function of the variable pitch auger 201 is to gradually disperse the adjacent oral liquid bottles by rotating its spiral blades, increase the spacing between adjacent bottles according to the needs of the sterilization equipment, and adjust the spacing between two adjacent oral liquid bodies 4 to be the same as the spacing required by the conveying device, so as to facilitate subsequent sterilization operations.

[0029] The output end of the variable-pitch auger 201 is connected to two oppositely arranged conveyor belts 202. These two conveyor belts 202 act as the first conveyor components, continuing to transport the oral liquid body 4, which has been adjusted in distance, forward. A sliding plate 203 of a certain length is provided at the bottom of each conveyor belt 202 along the conveying direction. The sliding plate 203 abuts against the edge of the bottom of the oral liquid body 4, with a hollowed-out center at the bottom to ensure the oral liquid bottles are stable during transport and do not collide with each other. This prevents the oral liquid body 4 from falling between the conveyor belts 202 during forward transport, ensuring optimal performance. Furthermore, the length of the sliding plate 203 is less than the length of the conveyor belt 202, allowing it to transport the oral liquid body 4 below the electric push rod 3 and roller assembly 301. The bottom of the housing 1 protrudes to one side. When a suction cup 5044 rotates with the chain 501 and reaches below the roller assembly 301, an oral liquid body 4 is conveyed out from above by the corresponding sliding plate 203. A vertically downward-facing electric push rod 3 is installed above the 2nd conveyor belt. The output end of the electric push rod 3 is connected to the mounting frame. The front end of the mounting frame drives the roller to protrude upward, causing a slight downward displacement when the oral liquid body 4 is conveyed forward. This allows the bottom of the oral liquid body 4 to move slightly towards the suction cup 5044, resulting in a tighter fit. The bottom surface of the mounting frame is equipped with a roller assembly 301. The gap of the roller assembly 301 is slightly smaller than the diameter of the top of the oral liquid bottle. By pressing down the electric push rod 3, the roller assembly 301 gently presses down the bottle. This, together with the suction cup 5044 at the bottom, also prevents the bottle from tipping over during conveying. The distance between the two conveyor belts 202 can be adjusted by the adjustment plate at the bottom, allowing the entire production line to be suitable for various types of oral liquids. Oral liquids are produced in sizes such as 10ml, 20ml, 100ml, and 200ml. The model of the variable pitch auger 201 must be adjusted according to the diameter of the oral liquid body 4. This allows for the production of various oral liquids with simple adjustment, convenient use, and improved performance.

[0030] The oral liquid body 4 is fed into the sterilization chamber via conveyor belt 202. The sterilization time is controlled by the rotation path of the oral liquid body 4 inside the sterilization chamber. At the exit of the sterilization chamber, there is also a conveyor belt 202. The outward rotation of these two conveyor belts 202 transports the sterilized oral liquid body 4 to the external receiving tray 2. The sliding plate 203 at the bottom prevents the oral liquid body 4 from falling and assists in the separation of the oral liquid body 4 from the suction cup 5044 to ensure the effectiveness of use. A manhole 104 is provided on the side of the chamber 1 to facilitate regular maintenance of the interior of the chamber 1.

[0031] The output end of the first conveyor is connected to the sterilization chamber, which conveys the oral liquid body 4 into the chamber 1. The sterilization chamber is designed with a conveying device for picking up the oral liquid bottles one by one, and a spraying device set along the conveying path.

[0032] The sterilization chamber is equipped with multiple sets of sprockets 5, which are connected by chains 501 to form a circulating conveying system. The sprockets 5 are driven by a motor 102 installed outside the chamber 1. The chains 501 are distributed in an S-shape inside the chamber 1. The sprockets 5 are arranged in a matching manner, with larger diameter sprockets 5 used to increase space when the oral liquid bodies 4 are arranged opposite each other, and smaller diameter sprockets 5 used when conveying back to back to reduce the space in the chamber 1. The conveying length and speed of the chains 501 are set according to the sterilization time, so that the sterilization time meets the sterilization requirements of 10-13 minutes. After passing through the input and output conveyor belts 202, the chains 501 are guided by the sprockets 5 to form a circulation, so that multiple oral liquid bodies 4 can be sterilized simultaneously inside the chamber 1. At the same time, two or more chambers 1 can be connected to the receiving tray 2 of the filling line, improving sterilization efficiency and production efficiency.

[0033] A connecting rod is fixed to the side of the chain 501, and the other end of the connecting rod is connected to a gripping device. The gripping device includes a functional tank 504 and a suction cup 5044. The suction cup 5044 is located on the top of the functional tank 504 and is used to adsorb the bottom of the oral liquid bottle. An upper piston 5041 and a lower piston 5042 are set inside the functional tank 504, and hydraulic oil is filled between them. The bottom of the lower piston 5042 is connected to a drive device. Through the action of the drive device, the lifting and lowering of the lower piston 5042 is controlled, thereby changing the vacuum degree in the suction cup 5044, realizing the gripping and release of the oral liquid bottle. When in use, when the lower piston 5042 moves downward, it drives the upper piston 5041 to move downward. When the lower piston 5042 moves downward, the upper piston 5041 drives the upper piston 5042 to move downward. As the moving block 5043 moves downward at the bottom of the suction cup 5044, the bottom of the oral liquid body 4 abuts against the suction cup 5044. When the moving block 5043 moves downward, the suction cup 5044 and the bottom of the oral liquid body 4 are tightly connected, causing the oral liquid body 4 to move along the conveying direction of the chain 501. Since the suction cup 5044 is connected to the bottom of the oral liquid body 4, most of the oral liquid body 4 is exposed inside the chamber 1, increasing the contact area with steam during sterilization. Compared with the existing situation where the oral liquid bodies 4 are close together during sterilization, the sterilization area is larger, the gap between the oral liquid bodies 4 is larger, the steam can better form a wrapping effect, the sterilization is more comprehensive, the heating is uniform, and the occurrence of bottle breakage is reduced.

[0034] The drive unit includes a drive rod 505 and a connecting ring 507. The top of the drive rod 505 is connected to the lower piston 5042, and the connecting ring 507 is connected to a track 503 set on the inner wall of the housing 1. The track 503 is arranged cyclically along the rotation direction of the chain 501. A sliding groove 502 with the same direction is provided above the track 503. A roller 506 is provided at the lower part of the functional tank 504 and is rolledly connected to the sliding groove 502. The roller 506 is engaged inside the sliding groove 502, so that the functional tank 504 can maintain extremely high stability when rotating along the chain 501. The track 503 has two opposite sides that are fixed to the inner wall of the housing 1 by fixing rods, which does not affect the passage of the drive rod 505. The drive rod 505 passes through the middle and is connected to the track 503 below. The connecting ring 507 is a sliding connection with a C-shaped structure, allowing the track 503 to be fixed to the side wall of the housing 1 by a fixing rod. During use, the chain 501 drives the functional can 504 and the drive rod 505 to rotate along the track 503. The roller 506 at the bottom of the functional can 504 supports the functional can 504 to maintain stability. By adjusting the distance between the track 503 and the slide 502, the drive rod 505 is controlled to drive the lower piston 5042 to move up and down. When the drive rod 505 moves down, the upper piston 5041 and the lower piston 5042 move down, increasing the suction force of the suction cup 5044. Throughout the sterilization process, as long as the distance between the slide 502 and the track 503 is maintained, the suction cup 5044 and the oral liquid body 4 can be kept in close contact. Sufficient suction is provided, and hydraulic oil is filled between the upper piston 5041 and the lower piston 5042 to reduce the impact of temperature changes on suction. This also ensures minimal impact on the suction of the suction cup 5044 even with small distance changes. Compared to using a metal piston directly, this provides greater stability and a certain buffering effect, ensuring the stability of the gripping device during transport. The distance between the track 503 and the chute 502 is transitioned using an arc-shaped track 503 during loading and unloading. During loading, the distance between the track 503 and the chute 502 below the roller assembly 301 gradually increases. As the oral liquid body 4 continues to be conveyed forward along the conveyor belt 202, the suction cup 5044 and the bottom of the oral liquid body 4... As the suction force gradually increases, the distance between the track 503 and the chute 502 remains constant after the oral liquid body 4 is output from the conveyor belt 202, enabling stable conveying. In the opposite direction during the unloading process, the sterilized oral liquid body 4 first enters between the two conveyor belts 202. After being clamped by the conveyor belts 202, the distance between the track 503 and the chute 502 gradually decreases. The upper piston 5041 and the lower piston 5042 drive the movable block 5043 to move upward, reducing the suction force of the suction cup 5044. At the same time, the suction cup 5044 turns under the drive of the chain 501 and disengages from the oral liquid body 4, completing the entire adsorption and sterilization release process. The entire structure is technically mature, easy to grasp and release, can be used for various oral liquids, and has significant economic benefits.

[0035] Multiple steam pipes are installed on the side wall inside the chamber 1, following the direction of movement of the oral liquid body 4. Multiple nozzles 6 are installed on the side wall of the steam pipes, facing the center, to ensure that the steam fully covers the oral liquid bottle. Preferably, the nozzles 6 face the bottle. A regulating valve 103 is installed on the outer wall of the chamber 1 to control the steam flow and temperature for optimal sterilization. Two sets of steam pipes are arranged opposite each other, with nozzles 6 evenly distributed on each set to ensure a balanced steam spray range and intensity, further improving sterilization efficiency.

[0036] An exhaust fan 101 is installed on the top of the sterilization chamber to remove excess steam and moisture from the chamber. The exhaust fan 101 is turned on intermittently to control the temperature inside the chamber. A drain pipe is installed at the bottom to facilitate the collection and drainage of condensate from the chamber.

[0037] Working principle: The filled oral liquid bottles fall from the filling machine into the receiving tray 2. After being dispersed by the variable pitch auger 201, they are conveyed to the sterilization chamber by the first conveyor. Inside the sterilization chamber, the gripping device grabs the oral liquid bottles one by one and moves them along the conveying path of the chain 501 to the spraying device. Steam is evenly sprayed onto the surface of the oral liquid bottles through the nozzle 6 to achieve comprehensive sterilization. After sterilization, the gripping device releases the oral liquid bottles to the next process, completing the entire sterilization process. This can realize automated sterilization treatment after oral liquid filling, improve production efficiency and sterilization effect, and ensure hygiene and safety in the production process.
