Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical technical field relates to a medicine box cover closing mechanism. BACKGROUND

[0002] The medicine bottles generally need to be packaged with medicine boxes before leaving the factory, and the medicine boxes are generally rectangular paper boxes. The two ends of the paper box are respectively provided with two pieces of oppositely arranged inner covers and one piece of outer cover, and the free end edge of the outer cover has a flange. When sealing the paper box, the outer cover is turned inward by the paper box sealing mechanism, and the flange is inserted into the paper box. Since it cannot be guaranteed that the included angle between the flange and the outer cover is always 90°, that is, the included angle between the flange and the outer cover is slightly larger than 90° or slightly smaller than 90°, the flange cannot be inserted into the paper box by the existing paper box sealing mechanism, resulting in sealing failure.

[0003] Therefore, the applicant has invented a paper box sealing mechanism [authorized publication number CN 216443849U], which comprises a base, a conveying belt arranged on the base, and a push rod driven by a power unit arranged on the base. The extension direction of the push rod is perpendicular to the conveying direction of the conveying belt. The upper part of the base is provided with a guide seat. The bottom of the guide seat has a first guide surface flush with the inner surface of the upper side of the paper box. The guide seat also has a second guide surface located on the side away from the paper box and extending upwardly and obliquely. The included angle between the second guide surface and the horizontal plane is less than or equal to 45°, which can accurately insert the flange into the paper box.

[0004] The above-mentioned paper box sealing mechanism can insert the flange with an included angle of about 90° between the outer cover into the paper box, but it needs to stop the paper box before performing the flange insertion operation, which is low in efficiency. When the flange is coplanar with the outer cover, the above-mentioned mechanism cannot operate it. UTILITY MODEL CONTENTS

[0005] The utility model aims at the above-mentioned problems existing in the prior art and provides a medicine box cover closing mechanism which can fold the flange first and then close the cover.

During transportation, the outer cover is first transported below the limiting block and then contacts the first flange block. The specific working process is as follows: the conveying belt drives the medicine box to move forward, the outer cover enters the second gap under the action of the second guide surface, then the flange enters the first guide surface from the upper surface of the mounting platform, is lifted upwardly by the first flange block and enters the first gap, and the flange is shaped by the first gap and the second gap arranged perpendicularly to each other, so that the flange is perpendicular to the outer cover in the subsequent process.

When the two are separated from the first gap, the flange still maintains a perpendicular state with the outer cover, ensuring that the subsequent closing action can be smoothly performed. The spring has moderate elasticity, and when the outer cover and the flange enter, the pressing wheel can be lifted, and the spring is compressed at this time.

DETAILED DESCRIPTION

[0023] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the accompanying drawings, but the present application is not limited to these embodiments.

[0024] As shown in Figure 1 and Figure 2 , the medicine box cover closing mechanism comprises a conveying belt 1 for conveying a medicine box a and a mounting platform 2 arranged at the side of the conveying belt 1, a plurality of vertical columns are arranged on the conveying belt 1 for limiting the position of the medicine box a, so as to ensure that the position of the medicine box a does not change relative to the conveying belt 1 during the cover closing process. As shown in Figure 1 , a first folding block 3 extending along the conveying direction of the conveying belt 1 is arranged on the mounting platform 2, the first folding block 3 is provided with a first guide surface 31 extending upwardly and obliquely from the upper surface of the mounting platform 2 along the length direction of the conveying belt 1, a limiting block 4 is further arranged on the mounting platform 2 and located at the side of the first folding block 3 close to the conveying belt 1, the limiting block 4 and the first folding block 3 have a first gap 5 with a thickness equal to that of the folding edge a2, the limiting block 4 and the mounting platform 2 have a second gap 6 with a thickness equal to that of the folding edge a2, the first gap 5 and the second gap 6 are perpendicular and connected, in order to suspend the limiting block 4, the limiting block 4 is connected to the first folding block 3 through a connecting block, the connecting block is located at the top of the limiting block 4 and the first folding block 3, and the distance from the connecting block to the upper surface of the mounting platform 2 is greater than the width of the folding edge a2, when the folding edge a2 stands up, it can pass through the first gap 5 without any obstruction.

[0025] In order to facilitate the outer cover a1 to enter the second gap 6, as shown in Figure 1As shown, a second guide surface 41 for guiding the outer cover a1 into the second gap 6 is provided at the lower part of the limiting block 4. The second guide surface 41 extends downward at an incline along the conveying direction of the conveyor belt 1 to the lower surface of the limiting block 4.

[0026] The upper surface of the mounting platform 2 is flush with the upper surface of the conveyor belt 1. The outer cover a1 of the medicine box a, which is conveyed by the conveyor belt 1, is parallel to the upper surface of the mounting platform 2. The distance from the first gap 5 to the medicine box a on the conveyor belt 1 is equal to the length of the outer cover a1. During transportation, the outer cover a1 is first transported to below the limiting block 4 before contacting the first folding block 3. The specific working process is as follows: The conveyor belt 1 drives the medicine box a forward, and the outer cover a1 enters the second gap 6 under the action of the second guide surface 41; then the flange a2 enters the first guide surface 31 from the upper surface of the mounting platform 2, and is lifted upward by the first folding block 3 and enters the first gap 5. The flange a2 is shaped by the mutually perpendicular first gap 5 and second gap 6, so that the flange a2 is perpendicular to the outer cover a1 in the subsequent process. The limiting block 4 is fixed on the first folding block 3, and the fixing point is located at the upper part of the first gap 5.

[0027] like Figure 1 As shown, the limiting block 4 has a third guide surface 42 on the side facing the first folding block 3, and the distance from the third guide surface 42 to the first folding block 3 gradually decreases along the conveying direction. Due to the presence of the third guide surface 42, the flange a2 with an angle of less than 90° with the outer cover a1 can be guided to the first gap 5, thereby increasing the applicability of this cover closing mechanism.

[0028] like Figure 3 and Figure 4 As shown, the limiting block 4 is located at the intersection of the first gap 5 and the second gap 6 and has a guide cavity extending perpendicular to the conveying direction and at a 45° angle to the upper surface of the mounting platform 2. A slide block 71 and a spring 72 acting on the slide block 71 are slidably provided in the guide cavity. A pressure roller 73 with a cutting edge is rotatably provided on the slide block 71. Under the action of the elastic force of the spring 72, the cutting edge of the pressure roller 73 presses against the intersection of the outer cover a1 and the flange a2.

[0029] The cutting edge of the pressure roller 73 can press against the intersection of the outer cover a1 and the flange a2. That is, the intersection is shaped by the cutting edge of the pressure roller 73. When the intersection of the flange a2 and the outer cover a1 passes the pressure roller 73, the cutting edge applies external force at the intersection, causing deformation and shaping of the internal structure. When the two parts separate from the first gap 5, the flange a2 remains perpendicular to the outer cover a1, ensuring smooth subsequent closing. The spring 72 has moderate elasticity; when the outer cover a1 and the flange a2 enter, it can lift the pressure roller 73, at which point the spring 72 is compressed.

[0030] In the embodiment, the first guide surface 31 is provided with a rounded corner at the intersection with the side of the first folding block 3 facing the limiting block 4. The rounded corner is contacted by the flange a2 during movement, so as to avoid scratching the flip cover.

[0031] As shown in Figure 1 and Figure 2 The installation platform 2 is provided with the second folding block 8, the height of the second folding block 8 gradually increases along the conveying direction of the conveying belt 1, and the distance between the second folding block 8 and the conveying belt 1 gradually decreases along the conveying direction of the conveying belt 1. The outer cover a1 can be folded to the side of the medicine box a by the second folding block 8, so as to achieve the purpose of conveying and closing the cover at the same time.

[0032] As shown in Figures 1-3 The upper side of the second folding block 8 is provided with the first guide block 9 extending along the conveying direction of the conveying belt 1, the lower side of the first guide block 9 is provided with the fourth guide surface 91 extending downwardly and obliquely along the direction perpendicular to the conveying direction of the conveying belt 1 to the insertion opening of the flange a2 of the medicine box a, the lower side of the first guide block 9 is provided with the second guide block 10, the upper side of the second guide block 10 is provided with the fifth guide surface 101 extending upwardly and obliquely along the direction perpendicular to the conveying direction of the conveying belt 1 to the insertion opening of the flange a2 of the medicine box a, the width of the second guide block 10 gradually decreases along the length direction of the conveying belt 1, and the minimum width of the second guide block 10 is smaller than the width of the flange a2.

[0033] The paper box moves along the conveying direction of the conveying belt 1 under the action of the conveying belt 1, the outer cover a1 is gradually lifted by the second folding block 8 and is turned to the side of the paper box, when the outer cover a1 is turned upwardly to a certain angle, the flange a2 slightly outwardly inclined on the outer cover a1 contacts the fourth guide surface 91 / the flange a2 slightly inwardly inclined contacts the fifth guide surface 101, and the flange a2 is introduced into the insertion opening of the flange a2 of the medicine box a under the action of the fourth guide surface 91 and the fifth guide surface 101.
