Description

Technical Field

[0001] The utility model belongs to the technical field of irradiation sterilization devices, and more specifically, particularly relates to an irradiation sterilization device. Background Art

[0002] An irradiation sterilization device is a device that uses a radiation source (such as γ-rays or electron beams) to sterilize or disinfect materials. Its main function is to eliminate or inhibit microorganisms in the materials, including bacteria, fungi, viruses, etc., so as to achieve the purpose of sterilization, disinfection or extending the shelf life of the materials.

[0003] At present, both ends of the irradiation chamber of some irradiation sterilization devices are blocked by installation curtains to prevent the irradiation light from emitting, so as not to affect the health of the staff. However, the texture of the curtains is relatively soft and is easily damaged during long-term friction with the goods. Therefore, it needs to be replaced regularly, which not only takes time and effort but also increases the cost. At the same time, the curtains are prone to curling during long-term use, so gaps are likely to occur between the curtains, resulting in a reduced shielding effect of the curtains, which will further affect the health of the staff.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an irradiation sterilization device is provided in order to achieve a more practical value purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an irradiation sterilization device, which is achieved by the following specific technical means:

[0006] An irradiation sterilization device includes a workbench. A conveying mechanism is installed on the upper end surface of the workbench. An irradiation chamber is installed on the upper end surface of the workbench. A pair of chute 1s are provided on one inner wall of the irradiation chamber. The chute 1s are rotatably connected to a lead screw 1. A slider 1 is threadedly connected to the periphery of the lead screw 1. A pair of chute 2s are provided on the inner wall of the irradiation chamber far from the pair of chute 1s. A limiting rod is installed in the chute 2s. A slider 2 is slidably connected to the periphery of the limiting rod. A baffle is installed between the slider 1 and the slider 2. A pair of through slots are provided at the top of the irradiation chamber. The top ends of the pair of baffles penetrate through the through slots and extend above the through slots. A chute 3 is provided between the pair of chute 2s on one inner wall of the irradiation chamber. A lead screw 2 is rotatably connected in the chute 3. A slider 3 is threadedly connected to the periphery of the lead screw 2. A rotary clamping cylinder is installed on one side of the slider 3.

[0007] Furthermore, a motor 1 is installed on one side of the upper end surface of the irradiation chamber close to one of the through slots. The output end of the motor 1 is installed with a driving synchronous pulley. The top end of one of the lead screws 1 penetrates through the upper end surface of the irradiation chamber and is connected to the driving synchronous pulley.

[0008] Further, the top end of another one of the lead screws passes through the upper end face of the irradiation chamber and is connected with a driven synchronous pulley, and the driving synchronous pulley is connected with the driven synchronous pulley through a synchronous belt.

[0009] Further, a second motor is installed on one side of the upper end face of the irradiation chamber away from the first motor, and the top end of the second lead screw passes through the upper end face of the irradiation chamber and is connected with the output end of the second motor.

[0010] Further, an irradiation light emitter is installed on the top of the irradiation chamber.

[0011] Further, a feeding sensor is installed on the inner wall of one side of the irradiation chamber away from the rotary clamping cylinder.

[0012] Further, a controller is installed on the outer wall of one side of the irradiation chamber.

[0013] Further, the baffle is made of aluminum.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the combined use of the feeding sensor, the first motor, the driving synchronous pulley, the driven synchronous pulley, the first lead screw, the first slider and the baffle, when the conveying mechanism sends an article into the irradiation chamber, after the feeding sensor detects the entry of an article, the first motor is started. The first motor drives the driving synchronous pulley to rotate, and the driving synchronous pulley drives the driven synchronous pulley to rotate through the synchronous belt, thereby driving a pair of first lead screws to rotate. Since the first lead screw is in threaded connection with the first slider, when the first lead screw rotates, it drives the first slider to move downward, and the first slider drives the baffle to move downward, so as to effectively block the irradiation light from shooting out of the irradiation chamber and avoid affecting the body of the staff. At the same time, the baffle is made of aluminum, which is not only relatively durable, but also has a good shielding effect on the irradiation light.

[0016] Through the combined use of the second motor, the second lead screw, the third slider and the rotary clamping cylinder, when the irradiation light emitter finishes the irradiation sterilization work on the upper part of the article, the second motor is started. The second motor drives the second lead screw to rotate. Since the second lead screw is in threaded connection with the third slider, when the second lead screw rotates, it drives the third slider to move downward, and the third slider drives the rotary clamping cylinder to move downward and clamp the article. Then, the article is controlled to move upward, and the article is driven to rotate 180° by the rotary clamping cylinder to turn the article over, and then the article is placed on the conveying mechanism, so that the irradiation light emitter performs the irradiation sterilization work on the lower part of the article, thereby improving the sterilization effect of the article.

A second slider 501 is slidably connected to the periphery of the limiting rod 5. A baffle 10 is installed between the first slider 401 and the second slider 501. A pair of through slots 303 are provided on the top of the irradiation box 3. The top ends of the pair of baffles 10 penetrate through the through slots 303 and extend above the through slots 303. A third chute 304 is provided on one inner wall of the irradiation box 3 between the pair of second chutes 302. A second lead screw 6 is rotatably connected to the third chute 304.

[0029] Wherein, a first motor 7 is installed on one side of the upper end surface of the irradiation box 3 close to one of the through slots 303. A driving synchronous pulley 402 is installed at the output end of the first motor 7. The top end of one of the first lead screws 4 penetrates through the upper end surface of the irradiation box 3 and is connected to the driving synchronous pulley 402.

[0030] Wherein, the top end of the other first lead screw 4 penetrates through the upper end surface of the irradiation box 3 and is connected to a driven synchronous pulley 403. The driving synchronous pulley 402 is connected to the driven synchronous pulley 403 through a synchronous belt.

[0031] Wherein, a second motor 8 is installed on one side of the upper end surface of the irradiation box 3 away from the first motor 7. The top end of the second lead screw 6 penetrates through the upper end surface of the irradiation box 3 and is connected to the output end of the second motor 8.

[0036] The working principle of this embodiment:

[0037] Through the combined use of the feeding sensor 12, the first motor 7, the driving synchronous pulley 402, the driven synchronous pulley 403, the first lead screw 4, the first slider 401 and the baffle 10, when the conveying mechanism 2 feeds an article into the irradiation chamber 3, after the feeding sensor 12 detects the entry of an article, the first motor 7 is started. The first motor 7 drives the driving synchronous pulley 402 to rotate. The driving synchronous pulley 402 drives the driven synchronous pulley 403 to rotate through the synchronous belt, thereby driving a pair of first lead screws 4 to rotate. Since the first lead screw 4 is threadedly connected to the first slider 401, when the first lead screw 4 rotates, it drives the first slider 401 to move downward.

At the same time, the material of the baffle 10 is aluminum, which is not only relatively durable but also has a good shielding effect on the irradiation light. During the downward movement of the baffle 10, it drives the second slider 501 to move downward on the limiting rod 5. When the baffle 10 blocks both ends of the irradiation chamber 3, the irradiation light emitter 9 is started. After the irradiation light emitter 9 completes the irradiation sterilization work on the upper part of the article, the second motor 8 is started. The second motor 8 drives the second lead screw 6 to rotate. Since the second lead screw 6 is threadedly connected to the third slider 601, when the second lead screw 6 rotates, it drives the third slider 601 to move downward. The third slider 601 drives the rotary clamping cylinder 11 to move downward and clamp the article, then controls the article to move upward, and then drives the article to rotate 180° through the rotary clamping cylinder 11 to turn over the article, and then places the article on the conveying mechanism 2, so that the irradiation light emitter 9 performs the irradiation sterilization work on the lower part of the article, thereby improving the sterilization effect of the article.
