Description
Technical Field
[0001] This utility model relates to the field of food packaging machinery technology, specifically a sterilization machine for bottled sauce bottles. Background Technology
[0002] Bottled sauces, such as chili sauce, ketchup, and salad dressing, often require sterilization during the production process to kill pathogenic and spoilage bacteria inside the bottles, effectively extending the product's shelf life. At the same time, the sterilization process can prevent microbial fermentation and gas production, avoiding the risk of bottle bulging or explosion during storage and transportation, thus ensuring food safety and product value.
[0003] In the production process of bottled sauces, empty bottles may become contaminated with bacteria, mold, and other microorganisms during storage and transportation. If they are not effectively sterilized before filling, these microorganisms will contaminate the sauce, causing it to spoil and deteriorate within its shelf life, resulting in problems such as bloating and mold growth, posing food safety risks. Traditional methods of sterilizing empty bottles, such as rinsing with disinfectant, pose a risk of chemical residues and require subsequent drying, making the process complex. Thermal sterilization is energy-intensive and unsuitable for empty plastic bottles. Ultraviolet (UV) sterilization, as a non-thermal, residue-free "cold sterilization" technology, is very suitable for sterilizing empty bottles. However, existing UV sterilization equipment often has a single irradiation angle, which can easily create blind spots at the bottom of the bottle and in shadow areas on the bottle body for sauce bottles that are deep or have complex shapes, leading to incomplete sterilization.
[0004] Therefore, a specialized sterilization device is needed that can irradiate all surfaces inside and outside the empty bottle from all angles without any blind spots. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a sterilization machine for bottled sauce bottles, which has the advantage of being able to sterilize sauce bottles in all directions without dead angles, thus solving the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: a sterilizer for bottled sauce bottles, including a support frame, a mesh conveyor belt for conveying the sauce bottles at the top of the support frame, a sterilization chamber fixedly mounted at the top of the support frame, a short-wave ultraviolet lamp at the top of the sterilization chamber, a sliding support assembly at the top of the short-wave ultraviolet lamp for supporting it, and a reciprocating drive assembly at the top of the sterilization chamber for driving the sliding support assembly. The reciprocating drive assembly drives the sliding support assembly and the short-wave ultraviolet lamp to reciprocate in the horizontal plane, thereby changing the irradiation position of the top ultraviolet light.
[0007] The sterilization chamber has side panels installed on both the front and back. The inner walls of the sterilization chamber and the inner walls of the side panels are coated with a UV reflective coating to reflect and enhance the intensity of ultraviolet light inside the chamber. Short-wave ultraviolet lamps are fixedly installed on the inner walls of the side panels to irradiate the sauce bottles from both sides. Short-wave ultraviolet lamps are fixedly installed on the inner walls at the bottom of the sterilization chamber to irradiate upwards from the bottom.
[0008] As a preferred embodiment of this utility model, the sliding support assembly includes a support plate, a short-wave ultraviolet lamp tube fixed to the bottom end of the support plate, a UV sensor for monitoring ultraviolet light intensity fixedly installed at the bottom end of the support plate for real-time monitoring of light intensity to ensure sterilization effect, sliding sleeves fixedly provided on both sides of the top end of the support plate, a guide rod slidably connected to the sliding sleeve, the guide rod being fixedly connected to the inside of the bracket to provide guidance for the horizontal movement of the support plate, a pad fixedly provided in the middle of the top end of the support plate, a guide post fixedly provided in the middle of the top end of the pad, and a ball bearing rotatably provided at the top end of the guide post.
[0009] As a preferred technical solution of this utility model, the reciprocating drive assembly includes a housing, the bottom end of which is fixedly connected to the middle of the top of the sterilization chamber. A cam is provided inside the housing, and a guide groove is provided on the surface of the cam. The top end of the guide post is slidably connected to the guide groove of the cam through a ball bearing. A support shaft that is rotatably connected to the housing is fixedly provided in the middle of the cam. A motor that drives the support shaft is fixedly installed on one side of the housing. By driving the cam with the motor, the rotational motion of the cam can be converted into the horizontal reciprocating motion of the support plate. The ball bearing can reduce friction.
[0010] As a preferred technical solution of this utility model, the top of the shell is fixedly connected to a top cover by screws, which facilitates the inspection and maintenance of internal structures such as cams. A channel is opened in the middle of the top of the sterilization chamber, and the cam and the channel are located on the same vertical plane, which can ensure the transmission between the cam and the guide column.
[0011] As a preferred technical solution of this utility model, the sterilization chamber is installed outside the mesh belt conveyor belt. The mesh size of the mesh belt conveyor belt is smaller than the diameter of the bottle cap of the bottled sauce to prevent the bottle from falling. Its material is stainless steel or Teflon that allows ultraviolet light to pass through, ensuring that the light emitted by the short-wave ultraviolet lamp tube at the bottom can effectively penetrate the mesh belt and illuminate the bottom of the bottle. The top of both sides of the support is equipped with rotatable drive rollers. The two drive rollers are connected by the mesh belt conveyor belt. A motor is fixedly installed on the top of one side of the support to drive one of the drive rollers.
[0012] As a preferred technical solution of this utility model, the sterilization chamber has inspection ports on both the front and back. A baffle is fixedly installed inside the inspection port, and rubber strips are embedded on the four sides of the baffle to enhance the sealing. The side plate is fixedly connected to the baffle by screws, which facilitates the disassembly and maintenance of the short-wave ultraviolet lamp tube on the side plate. The inlet and outlet of the sterilization chamber are equipped with curtains to prevent ultraviolet leakage and prevent ultraviolet light from leaking out and causing harm to the human body. Positioning strips are fixedly installed on both sides of the top of the sterilization chamber by screws. A support strip is fixedly installed on the bottom of one side of the positioning strip by screws. The top of the curtain is fixedly connected to the bottom of the support strip.
[0013] As a preferred embodiment of this utility model, a reinforcing frame is fixedly provided at the bottom of the bracket, and a number of reinforcing rods are fixedly provided inside the reinforcing frame to improve the stability of the overall structure. A number of foot pads are fixedly provided on both sides of the bottom of the reinforcing frame, and rubber pads are fixedly provided at the bottom of the foot pads to play the role of shock absorption and anti-slip.
[0014] As a preferred technical solution of this utility model, a first upright plate is fixedly provided in the middle of both sides of the bottom end of the sterilization chamber, and a second upright plate is fixedly provided in both sides of the top end of the reinforcing frame. The second upright plate and the first upright plate are located on the same vertical plane. The bottom end of the first upright plate and the top end of the second upright plate are fixedly connected to the support. The sterilization chamber, the support and the reinforcing frame are firmly connected into a whole by the first upright plate and the second upright plate.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This sterilizer for bottled sauce bottles, by setting up a short-wave ultraviolet lamp tube 1 that can move back and forth at the top, short-wave ultraviolet lamp tubes 2 fixed on both sides, and short-wave ultraviolet lamp tube 3 fixed at the bottom, combined with the UV reflective coating inside, creates a multi-angle, all-round, high-intensity and dead-angle-free ultraviolet light irradiation environment. The movement of the top lamp tube can dynamically cover the bottle mouth area, effectively solving the problem of insufficient irradiation of the bottom of the bottle due to the limitation of the bottle mouth size, ensuring that even the inside of deep or irregularly shaped bottles can be fully sterilized.
[0016] 2. This sterilizer for bottled sauce bottles achieves stable and smooth reciprocating motion of the top UV lamp tube through the design of sliding support components and cam-type reciprocating drive components. It has a compact structure and reliable operation. It adopts a mesh belt conveyor belt with light-transmitting material that allows the bottom UV rays to shine upwards while ensuring smooth conveying. The side plate design that can be easily disassembled ensures safe use and facilitates daily maintenance and lamp replacement. Attached Figure Description

[0021] In use, firstly, the mesh belt conveyor 9 is started by motor 211, so that the mesh belt conveyor 9 starts to run slowly. Next, motor 1504 of the reciprocating drive assembly 5 is started. Motor 1504 drives cam 502, which can convert the rotational motion of cam 502 into the horizontal reciprocating motion of support plate 401. The ball bearing 406 can reduce the friction, so that the short-wave ultraviolet lamp 13 at the top can start to move horizontally. Finally, short-wave ultraviolet lamp 27 and short-wave ultraviolet lamp 38 are turned on, so that the sterilization chamber 2 is filled with ultraviolet light. At this time, the UV reflective coating on the inner wall of sterilization chamber 2 and the inner wall of side plate 6 will begin to reflect and enhance the intensity of ultraviolet light. Bottled sauce bottles to be sterilized are placed evenly on the running mesh conveyor belt 9 with the caps facing upwards. The sauce bottles pass through the inlet curtain 12 of the sterilization chamber 2, enter the sterilization chamber 2, and are finally sent out from the outlet curtain 12. During this process, the reciprocating short-wave ultraviolet lamp 3 dynamically irradiates the top and mouth area of the bottle, ensuring that the inside of the bottle mouth is fully covered, solving the problem of insufficient irradiation at the bottom of deep bottles. The short-wave ultraviolet lamp 7 fixed on the side plates 6 irradiates from the sides of the bottle. The ultraviolet light emitted by the short-wave ultraviolet lamp 8 fixed at the bottom of the sterilization chamber 2 penetrates the mesh of the mesh conveyor belt 9 and irradiates the bottom of the bottle from bottom to top. Throughout the process, the UV reflective coating continuously reflects light, forming a high-intensity, multi-directional ultraviolet sterilization environment with no dead angles. After the sterilized sauce bottles are sent out from the outlet curtain 12, the next packaging process can begin. After all the sauce bottles have been sent out of the sterilization chamber 2, first turn off all the short-wave ultraviolet lamps, then turn off motor 1 504 to stop the reciprocating motion of the top lamp tubes, and finally turn off motor 2 11 to stop the conveyor belt from running.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
