[0002] The automatic folding and unfolding machine is used for folding single sterilization tray into a stack or unfolding the stack of sterilization tray into single automatic equipment. The sterilization tray enters the automatic folding and unfolding machine from other stations and is conveyed backward through the guide wheels on both sides. In order to ensure the normal lifting action of the sterilization tray, the sterilization tray is accurately positioned and stopped in the middle position of the automatic folding and unfolding machine, and then the folding and unfolding operation is performed. In the prior art, the folding and unfolding machine mainly has the following defects:

[0003] The positioning and blocking of the sterilization tray adopt a blocking stop mechanism, which is generally composed of a cylinder seat and a cylinder. The cylinder rod of the stop cylinder directly blocks the sterilization tray. The cylinder rod is subjected to collision for a long time, which causes inaccurate positioning and shortens the service life.

[0004] The lifting mechanism of the folding and unfolding machine is generally controlled by multiple screw jacks. The screw jacks are below the lifting platform. The screw jacks are connected with the lifting platform through flanges. The screw jacks are very inconvenient to disassemble during daily maintenance and repair. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0029] The utility model will be further explained in combination with the drawings and specific embodiments. It should be understood that these embodiments are only used for explaining the utility model and are not used for limiting the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the present application.

[0030] The embodiment provides a sterilization tray unfolding and folding machine, which mainly comprises a rack 1, a lifting platform 3, a guide wheel 4, a screw elevator 2, a flange assembly 7 and a blocking mechanism 5.

[0031] The rack 1 is used for main support, the lifting platform 3 is connected to the screw elevator 2 below through the flange assembly 7, and the lifting movement of the lifting platform 3 is driven by the screw elevator 2. The guide wheels 4 are arranged in two rows on both sides of the lifting platform 3 and are used for conveying sterilization trays.

[0032] A set of blocking mechanisms 5 is arranged on both sides of the lifting platform 3 corresponding to each row of guide wheels 4, and the blocking and positioning of the sterilization tray are realized through the blocking mechanisms 5 on both sides. As shown in the figure, the blocking mechanism 5 is arranged between the two adjacent guide wheels 4 at the end, and the blocking mechanism 5 mainly includes a cylinder seat 51, a lifting cylinder 52, a blocking column 54, and a limiting guide plate 55. Among them, the corresponding mounting hole is arranged on the cylinder seat 51 for fixing the blocking mechanism 5, and the cylinder seat 51 is fixed on the guide wheel support 6. A guide sleeve 53 is fixedly arranged on the cylinder seat 51, and the blocking column 54 is located in the guide sleeve 53 and can move up and down. Specifically, the blocking column 54 is in a column structure as a whole, hollow inside, and provided with a mounting hole 542 at the bottom. The lower end of the blocking column 54 passes through the guide sleeve 53 and is connected to the output rod of the lifting cylinder 52 through the screw passing through the mounting hole 542. The lifting cylinder 52 is fixed to the cylinder seat 51, and the lifting cylinder 52 drives the blocking column 54 to lift. When the limiting guide plate 55 on the blocking column 54 rises, it can stop and limit the sterilization tray.

[0033] As shown in the figure, in the embodiment, an inner plane 531 is arranged on the inner wall of the guide sleeve 53, and an outer plane 541 is arranged on the outer circle of the blocking column 54. The inner plane 531 is attached to the outer plane 541, which can limit the rotation of the blocking column 54 in the circumferential direction while not affecting the normal lifting of the blocking column 54.

[0034] In a preferred scheme provided in the embodiment, the limiting guide plate 55 is welded to the top end of the blocking column 54, that is, an installation plane is arranged on the upper part of the blocking column 54 in the circumferential direction, and the limiting guide plate 55 is welded to the installation plane to ensure the stability and firmness of the structure. At the same time, the limiting guide plate 55 is arranged to have an outwardly inclined guide slope structure, so that the two limiting guide plates 55 on both sides form a horn mouth structure, which is convenient for positioning the sterilization tray.

[0035] In a specific embodiment provided in the embodiment, the spiral elevator 2 and the lifting platform 3 are connected through a flange assembly 7, which is designed as a structure that can be easily disassembled.

[0036] Referring to the drawings, the flange assembly 7 comprises two half circular flanges 72 and a small flange 71, the small flange 71 is connected to the screw elevator 2, the upper surface of the two half circular flanges 72 is provided with clamping grooves 721, after the butt joint of the two half circular flanges 72, the small flange 71 is covered through the clamping grooves 721, at the same time, the two half circular flanges 72 are fixed to the lower side of the lifting platform 3 through screws. In the above structure, the lifting movement of the screw elevator 2 is transmitted to the lifting platform 3 through the small flange 71 and the half circular flanges 72 to drive the lifting platform 3 to move. When disassembly and maintenance are needed, only the two half circular flanges 72 need to be opened to realize the separation of the screw elevator 2 and the lifting platform 3, which has the advantages of convenient and quick disassembly.
