Description

Technical Field

[0001] The invention relates to the field of irradiation, and in particular to an irradiation box positioning mechanism and an irradiation device. Background Art

[0002] Irradiation is a chemical technology that uses the radiation of radioactive elements to change the molecular structure. It has significant effects in sterilization, extending the shelf life, improving quality, treating cancer, and safety and environmental protection. It is widely used in many fields such as food and medical care. For example, irradiation can effectively kill microorganisms such as bacteria, viruses, fungi and parasites in food, thereby reducing the number of pathogenic bacteria and fungi in food and extending the shelf life of food. With the demand of industrial production, there are more and more types of irradiation equipment, such as a disclosed irradiation box positioning mechanism (publication number CN113593746A). This type of irradiation equipment, with the help of a driving member in the clamping and fixing member, drives the two jaws to move toward or away from each other at the same time to fix and clamp the side wall of the irradiation box, and then uses a conveying mechanism to dynamically transport the clamped irradiation box to make the irradiation of the irradiation box uniform and improve the effect of irradiation treatment.

[0026] 1. This design is based on the positioning mechanism as the support platform of the irradiation box. After the irradiation box is placed on the positioning mechanism, the gravity of the irradiation box is used to press down and push out the brake gear in the positioning mechanism as a driving source. Then, when the items inside the irradiation box are irradiated, based on the drive of the reciprocating actuator, the combined displacement of the positioning mechanism and the irradiation box is promoted. At the same time, the meshing transmission of the brake gear and one set of gear row tooling is used to generate a self-locking thrust to push the positioning mechanism to self-clamp and position the irradiation box. Then, after the irradiation is completed, the meshing transmission of the brake gear and another set of gear row tooling is used to generate an unlocking thrust to self-unlock the positioning mechanism and the irradiation box, remove the irradiation box, and control the positioning mechanism to reset, so as to realize the self-positioning of the irradiation box and promote the integrated irradiation work. Its braking has good integrated linkage, and the braking is faster, which is beneficial to improve the irradiation efficiency.

[0027] 2. When the positioning mechanism is used to clamp and position the irradiation box and irradiate it, the braking length of the transmission rack in the two sets of gear row tooling can be adjusted based on the opposite drive adjustment of the two sets of propulsion slides by the propulsion braking mechanism to maintain a suitable braking length with the brake gear in the positioning mechanism, drive the positioning mechanism to maintain different clamping states, and perform self-clamping and positioning on irradiation boxes of different sizes, thereby improving flexibility and adaptability.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-3 The present invention provides a technical solution for an irradiation box positioning mechanism: an irradiation box positioning mechanism, comprising an irradiation box 1 and a positioning mechanism 2 for clamping the irradiation box 1, the positioning mechanism 2 comprising a support table 21, a plurality of groups of opposing screw rods 22 are circumferentially arranged inside the support table 21, and an opposing slide 24 is arranged on the outer side of the shaft of each group of opposing screw rods 22, a clamping arm 25 for clamping the irradiation box 1 is arranged on the upper end of the frame of the opposing slide 24, an opposing slide rail 23 is arranged directly below the shaft of each group of opposing screw rods 22, and the opposing slide rail 23 and the opposing slide 24 are slidably connected to each other, and when the opposing screw rod 22 rotates, the opposing slide 24 is driven to slide along the guide rail direction of the opposing slide rail 23, and then the clamping arm 25 is pushed to contract in opposite directions to clamp and fix the irradiation box 1.

[0039] A compression brake assembly for driving multiple groups of opposing screw rods 22 is arranged in the middle of the box frame of the irradiation box 1. The compression brake assembly includes a guide sleeve 211 installed in the middle of the support platform 21. A telescopic guide rod 28 is connected to the inside of the guide sleeve 211. A top support seat 27 extending from the support platform 21 is arranged at the top of the arm of the telescopic guide rod 28, and a brake gear 212 extending from the support platform 21 is arranged at the bottom end of the arm of the telescopic guide rod 28. A bevel gear A26 is arranged at one end of the shaft of each group of opposing screw rods 22, and a bevel gear B29 for pressing the bevel gear A26 is arranged at the upper end of the arm of the telescopic guide rod 28. When the telescopic guide rod 28 moves downward, the bevel gear B29 is driven to move downward and maintain meshing transmission with the bevel gear A26. Then, when the brake gear 212 is used as a driving source to drive the telescopic guide rod 28 to rotate, the bevel gear B29 is driven to move downward and maintain meshing transmission with the bevel gear A26, thereby promoting the linkage operation of multiple groups of opposing screw rods 22.

[0040] The outer ring sleeve of the telescopic guide rod 28 is provided with a compression spring 210 which elastically presses against the guide sleeve 211. The elastic compression force of the compression spring 210 is less than the self-weight of the irradiation box 1. When the irradiation box 1 is placed on the positioning mechanism 2, its self-weight is greater than the elastic supporting force of the compression spring 210. Therefore, the combination of the top support seat 27 and the telescopic guide rod 28 is pressed down to push the brake gear 212 down and push it out, keeping it horizontally aligned with the two sets of gear row tooling 7, serving as a driving source to drive the positioning mechanism 2 to clamp. After the irradiation box 1 on the subsequent positioning mechanism 2 is removed, the brake gear 212 moves up again under the reset of the compression spring 210, and is offset from the gear row tooling 7 up and down, so that the positioning mechanism 2 can be reset by reciprocating translation.
