Description

Technical Field

[0001] The present application relates to the field of cartons and pertains to a fully automatic folding and sealing machine. Background Art

[0002] Cartons are widely used in packaging, such as the packaging structure shown in publication number CN114590450A, which consists of a conveyor belt and a folding mechanism. The cardboard at the top opening of the carton is vertically erected on the carton. When in use, items are put into the carton and placed on the conveyor belt. When the carton is transported to the bottom of the folding mechanism, the four pieces of cardboard on the top of the carton are folded and sealed with adhesive tape through the folding mechanism to complete the sealing.

[0003] However, in actual production, workers may inadvertently press the cardboard on the top of the carton when loading goods, causing the cardboard to bend downward. When passing through the folding mechanism, the cardboard is not within the movement range of the folding arm, resulting in the folding mechanism being unable to fold the cardboard.

[0004] Therefore, in order to solve the above technical problems, it is necessary to provide an innovative carton upper folding and packaging mechanism to overcome the above defects in the prior art. Utility Model Content

[0005] The utility model aims to provide a carton upper part folding and packing mechanism which can automatically reset the carton paperboard.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a first conveyor belt and a folding mechanism, and also includes two folding rods, a front roller, a rear roller and a second conveyor belt. The second conveyor belt is located at the front end of the first conveyor belt. The two folding rods are respectively installed on both sides of the front end of the first conveyor belt to limit the movement range of the carton. One end of the folding rod is located between the first conveyor belt and the second conveyor belt, and the other end is located above the first conveyor belt. The front roller and the rear roller are installed on the folding rod. The length of the front roller is greater than the length of the rear roller. The front roller is linearly connected with the rear roller. The distance between the front roller and the rear roller is greater than the length of the carton. Limiting parts are installed on both sides of the first conveyor belt to limit the contact between the front roller and the rear roller and the first conveyor belt.

[0007] By adopting the above technical solution, the carton moves forward through the first conveyor belt and is linked to the front roller located on the folding rod to move. The front roller pushes the front plate of the carton to a suitable position while moving upward. The front roller is linked to the rear roller, and the rear roller pushes the rear plate of the carton to a suitable position, so that the folding mechanism can fold the front and rear plates of the carton.

[0008] The upper folding and packaging mechanism of the carton of the utility model is further configured as follows: the limiting part includes a support platform fixedly connected to both sides of the first conveyor belt, and support columns are fixedly connected to the support platform. The spacing between the two support columns is greater than the length of the rear roller and less than the length of the front roller. The support columns and the folding rod cooperate with each other to limit the front roller above the first conveyor belt.

[0009] By adopting the above technical solution, when the front roller pushes the front plate of the carton and returns to the bottom of the folding rod along the folding rod, the support column is used to limit the movement range of the front roller to prevent the front roller from contacting the first conveyor belt.

[0010] The upper folding and packaging mechanism of the carton of the utility model is further configured as follows: the limiting part also includes a support column and a slide, the support column is installed on the support platform, the slide is installed on the support column, the top surface of the slide is higher than the top surface of the first conveyor belt, the end of the slide is located between the first conveyor belt and the second conveyor belt, and the slide is used to limit the contact between the rear roller and the first conveyor belt.

[0011] By adopting the above technical solution, after the rear roller pushes the rear plate, it returns to the bottom of the retracting rod along the retracting rod, and the slide is used to limit the movement range of the rear roller to prevent the rear roller from contacting the first conveyor belt.

[0012] The carton upper folding and packing mechanism of the utility model is further configured as follows: a clamping groove for limiting the movement of the rear roller is provided at the end of the folding rod.

[0013] By adopting the above technical solution, the clamping groove is used to limit the moving range of the rear roller, thereby preventing the rear roller from sliding on the retracting rod.

[0014] The carton upper folding and packing mechanism of the utility model is further configured as follows: an inclined surface of a guide slot is provided at the end of the slide.

[0015] By adopting the above technical solution, the inclined surface facilitates the rear roller to be moved out of the slot.

[0016] The carton upper folding and packaging mechanism of the utility model is further configured as follows: a roller one is rotatably connected to the front roller, and the roller one is rotatably connected to the upper part of the folding rod.

[0017] By adopting the above technical solution, when the front roller is located on the folding rod and the carton and moves, the rotation direction of the roller one is opposite to the rotation direction of the front roller one, thereby reducing the friction of the front roller on the carton.

[0018] The carton upper folding and packing mechanism of the utility model is further configured as follows: a front roller is rotatably connected to a front drum, a rear roller is rotatably connected to a rear drum, and the front drum and the rear drum are linearly connected.

[0019] By adopting the above technical solution, the front roller and the rear roller can reduce the friction between the front roller and the rear roller.

[0020] The carton upper folding and packing mechanism of the utility model is further configured as follows: a folding rod is rotatably connected to a supporting platform through a torsion spring.

[0021] By adopting the above technical solution, the folding rod is rotated toward the first conveyor belt by the torsion spring, so that the folding rod can position the carton, and can move the left and right plates of the carton to appropriate positions and then fold them through the folding mechanism.

[0022] The carton upper folding and packaging mechanism of the utility model is further configured as follows: the folding rod is arc-shaped.

[0023] By adopting the above technical solution, it is convenient to push the front roller to the top end of the folding rod.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] 1. The front roller and the rear roller of the folding and packing mechanism on the upper part of the carton in the utility model can push the front plate and the rear plate to a suitable position so that the folding structure can fold the carton.

[0033] Please refer to the instruction manual Figure 1 To Attachment Figure 5As shown, the utility model is a carton upper folding and packaging mechanism, the second conveyor belt 2 is located at the front end of the first conveyor belt 1, and the carton 4 is transported to the first conveyor belt 1 through the second conveyor belt 2.

[0034] Two folding rods 3 are respectively installed on both sides of the front end of the first conveyor belt 1 to limit the moving range of the carton 4. One end of the folding rod 3 is located between the first conveyor belt 1 and the second conveyor belt 2, and the other end is located above the first conveyor belt 1. The folding rod 3 pushes the left plate 41 and the right plate 42. After being pushed to a suitable position, the carton 4 is folded by the folding mechanism. In this embodiment, the folding rod 3 is rotatably connected to the supporting platform 71 through the torsion spring 31. The folding rod 3 is rotated toward the direction of the first conveyor belt 1 by the torsion spring 31, so that the folding rod 3 can position the carton 4. The folding rod 3 is arc-shaped, which is convenient for pushing the front roller 5 to the top of the folding rod 3.

[0035] A front roller 5 and a rear roller 6 are installed on the folding rod 3. The length of the front roller 5 is greater than that of the rear roller 6. The front roller 5 is linearly connected to the rear roller 6. When the front roller 5 moves, it can drive the rear roller 6 to move. The distance between the front roller 5 and the rear roller 6 is greater than the length of the carton 4, so that the front roller 5 drives the rear roller 6 to move. When the carton 4 moves forward through the first conveyor belt 1, the front roller 5 is linked to move on the folding rod 3. When the front roller 5 moves upward, it pushes the front plate 43 of the carton 4 to a suitable position, and the front roller 5 is linked to the rear roller 6 to move. The rear roller 6 can push the rear plate 44 of the carton 4 to a suitable position, so that the folding mechanism can fold the front plate 43 and the rear plate 44 of the carton 4.

[0036] Limiting members 7 are installed on both sides of the first conveyor belt 1 to limit the contact between the front roller 5 and the rear roller 6 and the first conveyor belt 1. The limiting members 7 include support platforms 71 fixedly connected to both sides of the first conveyor belt 1, and support columns 72 are fixedly connected to the support platforms 71. The spacing between the two support columns 72 is greater than the length of the rear roller 6 and less than the length of the front roller 5. The support columns 72 cooperate with the folding rod 3 to limit the front roller 5 above the first conveyor belt 1. When the front roller 5 pushes the front plate 43 of the carton 4 and returns to the bottom of the folding rod 3 along the folding rod 3, the support columns 72 are used to limit the movement range of the front roller 5 to prevent the front roller 5 from contacting the first conveyor belt 1.

[0037] The limiting member 7 also includes a support column 72 and a slide 73. The support column 72 is installed on the support platform 71, and the slide 73 is installed on the support column 72. The top surface of the slide 73 is higher than the top surface of the first conveyor belt 1, and the end of the slide 73 is located between the first conveyor belt 1 and the second conveyor belt 2. The slide 73 is used to limit the contact between the rear roller 6 and the first conveyor belt 1. After the rear roller 6 pushes the rear plate 44, it returns to the slot 30 at the bottom of the retracting rod 3 along the retracting rod 3. The slide 73 is used to limit the movement range of the rear roller 6 to prevent the rear roller 6 from contacting the first conveyor belt 1. The end of the slide 73 is provided with an inclined surface 730 of the guiding slot, and the inclined surface 730 facilitates the removal of the rear roller 6 from the slot 30.

[0038] The front roller 5 is rotatably connected to a roller 51, which is rotatably connected above the folding rod 3. When the front roller 5 moves on the folding rod 3 and the carton 4, the rotation direction of the roller 51 is opposite to the rotation direction of the front roller 5, thereby reducing the friction of the front roller 5 on the carton 4.

[0039] The front roller 5 is rotatably connected to a front drum 52 , and the rear roller 6 is rotatably connected to a rear drum 53 . The front drum 52 and the rear drum 53 are linearly connected, and the front drum 52 and the rear drum 53 can reduce friction between the front drum 5 and the rear drum 6 .

[0040] The working principle of the carton upper folding and packing mechanism of the utility model is as follows:

[0041] First, place the carton 4 on the second conveyor belt 2, start the second conveyor belt 2 and the first conveyor belt 1, and transfer the carton 4 to the top of the first conveyor belt 1. While the carton 4 moves forward, the folding rod 3 pushes the carton 4 to the specified position, and pushes the left plate 41 and the right plate 42 to be perpendicular to the ground. The carton 4 is linked with the front roller 5, so that the front roller 5 moves on the path of the folding rod 3, and the front roller 5 pushes the front plate 43 to be perpendicular to the ground. At the same time, the front roller 5 is linked with the rear roller 6, so that the rear roller 6 is close to the front plate 43. The back of the carton 4 moves upward, and at the same time, the rear roller 6 pushes the rear plate 44 to be perpendicular to the ground, and then the front roller 5 moves to the top of the left plate 41 and the right plate 42, and the folding mechanism folds the front plate 43 and the rear plate 44, and then folds the left plate 41 and the right plate 42, so that the front roller 5 falls onto the folding rod 3 and returns to the support column 72 along the path of the folding rod 3, and the rear roller 6 returns to the card slot 30 along the path of the folding rod 3 through the slide 73, and repeats the above steps to complete the process of folding the upper part of the carton 4.
