Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical technical field relates to a medicine bottle packing carton sealing mechanism. BACKGROUND

[0002] The medicine bottle is generally packaged by medicine box before leaving factory, and the medicine box generally adopts the paper box of cuboid. 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 turn-up. When the paper box is sealed, the outer cover is turned inwards by the paper box sealing mechanism, and the turn-up is inserted into the paper box. Since the included angle between the turn-up and the outer cover cannot be guaranteed to be always 90°, that is, the included angle between the turn-up and the outer cover is slightly greater than 90° or slightly less than 90°, the turn-up 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. A guide seat is arranged above the base. 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 turn-up into the paper box.

[0004] Since the push rod is located on the side of the conveying belt, the outer cover needs to be inserted into the paper box after the paper box is stopped, which is low in efficiency. Moreover, the guide block needs to be withdrawn after the outer cover is inserted into the paper box for a distance, which also reduces the sealing efficiency. UTILITY MODEL CONTENTS

[0005] The utility model aims at the above-mentioned problems existing in the prior art and provides a medicine bottle packing carton sealing mechanism with high sealing efficiency.

[0006] The utility model can be realized by the following technical scheme:

[0007] The medicine bottle packing carton sealing mechanism comprises a conveying belt and a positioning structure arranged on the conveying belt and used for positioning the paper box. A turn-up block is arranged on the side of the conveying belt. The height of the turn-up block gradually increases along the conveying direction of the conveying belt. The distance between the turn-up block and the conveying belt gradually decreases along the conveying direction of the conveying belt. A first guide block is arranged above the turn-up block and extends along the conveying direction of the conveying belt. The bottom of the first guide block has a first guide surface flush with the inner surface of the upper side of the paper box. The side away from the paper box of the first guide surface is connected with a second guide surface. The second guide surface extends upwardly and obliquely from the intersection line between the first guide surface and the second guide surface to the side away from the paper box.

[0008] The cartons move towards the conveying direction of the conveying belt under the action of the conveying belt, the outer cover on the cartons is gradually lifted by the edge folding block and turns to the side of the carton, when the outer cover turns up to a certain angle, the edge of the outer cover contacts the second guide surface, and moves below the first guide surface under the guidance of the second guide surface, and finally is inserted into the carton.

[0009] The included angle between the second guide surface and the horizontal plane is less than or equal to 45°, which is beneficial to guide the outwardly turned edge to be perpendicular to the outer cover, and facilitates the insertion of the edge into the carton.

[0010] In the above sealing mechanism of the carton for medicine bottles, the lower side of the first guide block is provided with a second guide block extending along the conveying direction of the conveying belt, the top of the second guide block is provided with a third guide surface opposite to the first guide surface, the side of the third guide surface away from the side edge of the carton is connected with a fourth guide surface, the fourth guide surface extends downwardly and obliquely from the intersection line of the third guide surface to the side away from the carton, and the front end of the second guide block is separated from the inner side of the outer cover when the edge of the outer cover is inserted into the carton for a distance.

[0011] The minimum width of the second guide block is the width of the edge, the length direction of the edge is the conveying direction of the conveying belt, and the width direction of the edge is perpendicular to the outer cover. The included angle between the fourth guide surface and the horizontal plane is less than or equal to 45°, when the included angle between the edge and the outer cover is less than 90°, the edge contacts the fourth guide surface under the action of the edge folding block, and the edge turns outwardly relative to the outer cover under the action of the fourth guide surface, so as to increase the included angle between the edge and the outer cover, and the edge can be accurately inserted into the carton in cooperation with the second guide surface, the first guide surface and the third guide surface. The distance between the first guide surface and the third guide surface is equal to or slightly greater than the thickness of the edge.

[0012] In the above sealing mechanism of the carton for medicine bottles, the width of the second guide block gradually decreases along the length direction of the conveying belt, and the minimum width of the second guide block is less than the width of the edge. During the conveying of the carton, the outer cover is gradually closed to the carton.

[0013] In the above sealing mechanism of the carton for medicine bottles, the side of the second guide block close to the conveying belt has a first side surface extending along the conveying direction and vertically downward, the side of the second guide block away from the conveying belt has a second side surface, and the distance between the first side surface and the second side surface gradually decreases along the conveying direction of the conveying belt.

[0014] In the above sealing mechanism of the carton for medicine bottles, the second side surface extends gradually from top to bottom and close to the side of the conveying belt. The second side surface arranged obliquely provides a space for the closing of the outer cover, so that the edge can effectively contact the fourth guide surface.

[0015] In the above medicine bottle packaging carton sealing mechanism, the lowest point of the upper surface of the folding block is lower than the upper surface of the conveying belt. The purpose of this arrangement is to lift the outer cover in a horizontal state upward and fold the outer cover to the side of the carton.

[0016] In the above medicine bottle packaging carton sealing mechanism, the rear end of the first guide block is provided with a first connecting block, and the rear end of the second guide block is connected to the first connecting block.

[0017] The first guide block and the second guide block are connected through the first connecting block, which ensures the relative position between the first guide block and the second guide block. In order to adapt to the different thickness of the flange, the distance between the first guide block and the second guide block can be adjusted. The adjustment method is that the first guide block and / or the second guide block can slide on the first connecting block, and after adjustment, it can be locked by bolts.

[0018] In the above medicine bottle packaging carton sealing mechanism, the side of the folding block away from the conveying belt is provided with a second connecting block, and the first guide block is connected to the second connecting block.

[0019] In the above medicine bottle packaging carton sealing mechanism, the positioning structure includes a limiting column provided on the conveying belt.

[0020] Each carton is provided with at least five limiting columns: two limiting columns are respectively arranged on the two sides of the carton, and one limiting column is arranged on the side of the carton away from the folding block. The width direction and the length direction of the carton are limited by the at least five limiting columns.

[0021] When the conveying belt works, it drives the carton positioned by the limiting column to move along the conveying direction of the conveying belt. The outer cover on the carton is gradually lifted up by the folding block. When the outer cover is lifted to a certain angle, the flange on the outer cover is pressed on the fourth guide surface. With the conveying of the conveying belt, the flange moves forward along the fourth guide surface and gradually approaches the carton direction under the action of the folding block. When the flange abuts against the second guide surface, the flange is guided between the first guide surface and the third guide surface under the joint action of the second guide surface and the fourth guide surface. Throughout the process, the outer cover does not contact the second guide block. When the flange is just inserted into the carton, the front end of the second guide block has not yet come out from the inner side of the outer cover. When the flange is inserted for a distance, the front end of the second guide block comes out from the inner side of the outer cover. With the continuous conveying of the conveying belt, the folding block pushes the outer cover, so that the flange is completely inserted into the carton.

[0022] Compared with the prior art, the medicine bottle packaging carton sealing mechanism has the following advantages:

[0023] During the process of inserting the outer cover's flange into the cardboard box, the cardboard box is constantly being conveyed, greatly improving work efficiency; the flange is guided by the second and fourth guide surfaces, and limited by the first and third guide surfaces, so that the flange can be accurately inserted into the cardboard box; the whole process does not require manual supervision and has a high degree of automation.

Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figure 1 The sealing mechanism for the medicine bottle packaging carton a shown includes a conveyor belt 1 and a positioning structure on the conveyor belt 1 for positioning the carton a. In this embodiment, the positioning structure includes limiting posts 7 on the conveyor belt 1, with five limiting posts 7 for each carton a: two limiting posts 7 on each side of the carton a, and one limiting post 7 on the side of the carton a away from the side to be sealed. The five limiting posts 7 limit the width and length of the carton a, preventing displacement of the carton a relative to the conveyor belt 1.

[0031] like Figure 1 As shown, a folding block 2 is provided on the side of the conveyor belt 1. The height of the folding block 2 gradually increases along the conveying direction of the conveyor belt 1, and the distance between the folding block 2 and the conveyor belt 1 gradually decreases along the conveying direction of the conveyor belt 1. The lowest point of the upper surface of the folding block 2 is lower than the upper surface of the conveyor belt 1, which can lift the outer cover a1, which is in a horizontal state, and fold the outer cover a1 towards the side of the cardboard box a. The folding block 2 and the conveyor belt 1 are fixed on the same base.

[0032] As shown in Figures 1-3 , the upper side of the folding block 2 is provided with a first guide block 3 extending along the conveying direction of the conveying belt 1, the bottom of the first guide block 3 is provided with a first guide surface 31 flush with the inner surface of the upper side of the carton a, the second guide surface 32 is connected to the side of the first guide surface 31 away from the carton a, and the second guide surface 32 extends upwardly and away from the carton a. The angle between the second guide surface 32 and the horizontal plane is less than or equal to 45°, which is conducive to guiding the outwardly folded flange a2 to be perpendicular to the outer cover a1, and facilitating the insertion of the flange a2 into the carton a.

[0033] As shown in Figure 2 and Figure 3 , the lower side of the first guide block 3 is provided with a second guide block 4 extending along the conveying direction of the conveying belt 1, the top of the second guide block 4 is provided with a third guide surface 41 opposite to the first guide surface 31, the fourth guide surface 42 is connected to the side of the third guide surface 41 away from the carton a, and the fourth guide surface 42 extends downwardly and away from the carton a. When the flange a2 on the outer cover a1 is inserted into the carton a for a distance, the front end of the second guide block 4 is separated from the inner side of the outer cover a1. The minimum width of the second guide block 4 is equal to the width of the flange a2, the length direction of the flange a2 is the conveying direction of the conveying belt 1, and the width direction of the flange a2 is perpendicular to the outer cover a1. The angle between the fourth guide surface 42 and the horizontal plane is less than or equal to 45°. When the angle between the flange a2 and the outer cover a1 is less than 90°, the flange a2 is brought into contact with the fourth guide surface 42 under the action of the folding block 2, and the flange a2 is turned outwardly relative to the outer cover a1 under the action of the fourth guide surface 42, thereby increasing the angle between the flange a2 and the outer cover a1, and cooperating with the second guide surface 32, the first guide surface 31 and the third guide surface 41 to accurately insert the flange a2 into the carton a. The distance between the first guide surface 31 and the third guide surface 41 is equal to or slightly greater than the thickness of the flange a2.

[0034] As shown in Figure 2 and Figure 4 , the width of the second guide block 4 gradually decreases along the length direction of the conveying belt 1, and the minimum width of the second guide block 4 is less than the width of the flange a2. During the forward conveying of the carton a, the outer cover a1 is gradually brought closer to the carton a.

[0035] In this embodiment, the second guide block 4 is provided with a first side surface extending along the conveying direction and vertically downwardly on the side close to the conveying belt 1, and the second guide block 4 is provided with a second side surface on the side away from the conveying belt 1, and the distance between the first side surface and the second side surface gradually decreases along the conveying direction of the conveying belt 1.

[0036] As shown in Figure 2 andFigure 3 As shown, the second side gradually extends from top to bottom towards the side closer to the conveyor belt 1. The inclined second side provides clearance for the outer cover a1 to close, allowing the flange a2 to effectively contact the fourth guide surface 42.

[0037] like Figure 2 and Figure 4 As shown, the rear end of the first guide block 3 is provided with a first connecting block 5, and the rear end of the second guide block 4 is connected to the first connecting block 5. The first guide block 3 and the second guide block 4 are connected by the first connecting block 5, ensuring the relative position between the first guide block 3 and the second guide block 4. To accommodate flanges a2 of different thicknesses, the distance between the first guide block 3 and the second guide block 4 can be adjusted. The adjustment method is that the first guide block 3 and / or the second guide block 4 can slide on the first connecting block 5, and after adjustment, it can be locked with bolts.

[0038] like Figure 2 and Figure 4 As shown, a second connecting block 6 is provided on the side of the folded edge block 2 away from the conveyor belt 1, and the first guide block 3 is connected to the second connecting block 6.

[0039] When conveyor belt 1 is working, it drives the cardboard box a, which is positioned by the limiting post 7, to move along the conveying direction of conveyor belt 1. The outer cover a1 on cardboard box a is gradually lifted upward by the folding block 2. When the outer cover a1 is lifted to a certain angle, the flange a2 on the outer cover a1 presses against the fourth guide surface 42. As the conveyor belt 1 is conveyed, the flange a2 moves forward along the fourth guide surface 42 and gradually moves towards cardboard box a under the action of the folding block 2. When the flange a2 touches the second guide surface 32, the flange a2 is lifted by the combined action of the second guide surface 32 and the fourth guide surface 42. Edge a2 is led between the first guide surface 31 and the third guide surface 41. Throughout the process, the outer cover a1 does not contact the second guide block 4, or the outer cover a1 contacts the second guide block 4 in the front section and gradually separates from the second guide block 4 in the rear section. When the flange a2 is just inserted into the paper box a, the front end of the second guide block 4 has not yet come out from the inside of the outer cover a1. After the flange a2 is inserted a certain distance, the front end of the second guide block 4 comes out from the inside of the outer cover a1. As the conveyor belt 1 continues to convey, the folding block 2 pushes the outer cover a1, so that the flange a2 is fully inserted into the paper box a.
