Description

Technical Field

[0001] This utility model relates to the technical field of carton sealing, and in particular to a carton side sealing structure. Background Technology

[0002] In the production process of packaging cartons, in order to facilitate the forming of the packaging cartons and prevent the cartons from becoming loose, it is necessary to seal the edges of the cartons to form the carton.

[0003] In factory carton sealing production lines, the carton input conveyor is perpendicular to the conveying direction of the sealing machine. Traditionally, a pushing mechanism is installed at the input conveyor to change the direction and push the carton into the sealing machine. Because the input conveyor is in a continuous conveying state, the pushing mechanism needs to maintain a relatively precise pushing speed and posture, which is difficult to control and makes it hard to ensure that the carton enters the sealing machine with the correct posture. During edge sealing, the sealing machine needs to simultaneously adhere tape to the top and sides of the carton. When the tape is adhered to the top of the carton, because the conveyor is constantly conveying, the pushing mechanism cannot ensure that the carton enters the sealing machine with the correct posture. It is even more difficult to ensure that the tape adheres correctly to the corners of the carton. The tape is prone to deviation and lifting during edge sealing, resulting in poor sealing quality. Utility Model Content

[0004] To overcome the technical problem in existing technologies where cartons cannot enter the sealing machine in the correct direction, resulting in misalignment during sealing and poor sealing effect, this utility model provides a carton side sealing structure, including a pressing part, a support, a transmission part, and an auxiliary part. The pressing part is located at the bottom end of the transmission part, and both the pressing part and the transmission part are slidably connected to the support. The transmission part drives the pressing part to move up and down in the vertical direction. The auxiliary part is located at the front end of the pressing part. The pressing part includes a pressing block, and the auxiliary part includes a first guide rod connected to the pressing block. The first guide rod can change the direction of the carton and transport it to the bottom end of the pressing block.

[0005] Furthermore, the auxiliary part is provided with two first guide rods, which are arranged in parallel and their lengths extend to both sides of the pressing block.

[0006] Furthermore, the auxiliary part also includes a second guide rod, which is located beside the first guide rod, and the height of the second guide rod in the vertical direction is lower than that of the first guide rod.

[0007] Furthermore, both the first guide rod and the second guide rod are provided with an abutment section, which is arranged in an arc shape and faces upward.

[0008] Furthermore, the pressing part also includes a sliding plate, which is fixedly connected to the pressing block. A first slide rail is provided on one side of the bracket, and the sliding plate is matched and connected to the first slide rail.

[0009] Furthermore, it also includes a drive cylinder, the two ends of which are respectively connected and fixed to the slide plate and the bracket.

[0010] Furthermore, the driving cylinder is a tension cylinder.

[0011] Furthermore, the transmission unit includes a mounting bracket, the mounting bracket is provided with a sliding rod, and a second slide rail is provided on the other side of the bracket, the sliding rod being matched and connected with the second slide rail.

[0012] Furthermore, the transmission unit also includes a drive motor and a sprocket transmission mechanism. The drive motor is fixedly mounted on the mounting bracket and connected to the sprocket transmission mechanism. The bracket is provided with a connecting plate, and both ends of the sprocket transmission mechanism are connected to the connecting plate.

[0013] Beneficial effects:

[0014] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0015] The side sealing structure is located in the carton sealing machine on the carton conveying mechanism. This side sealing structure is perpendicular to the carton conveying mechanism. The transmission part, support, and pressing part of the side sealing structure are connected sequentially from top to bottom, while the auxiliary part is located at the front end of the pressing part and is positioned opposite to the carton conveying direction. The transmission part and the pressing part are connected by the support, which can drive the support to slide, allowing the support to drive the pressing part to move up and down in the vertical direction of the sealing machine. The auxiliary part is positioned opposite to the carton conveying direction, and its first guide rod is connected to the pressing block of the pressing part. When the carton is conveyed to the sealing machine along the conveying mechanism, the sealing machine's pushing mechanism pushes the carton. In this side sealing structure, the transmission unit drives the pressing part to move up and down in the vertical direction, but the conveying mechanism continues to convey the carton. As the pressing part moves downward, the first guide rod intercepts the carton. After being intercepted, the carton contacts the pushing mechanism of the sealing machine. The pushing mechanism of the sealing machine continues to push the carton, causing it to change direction and move towards the bottom of the pressing block. This achieves the reversal of the carton's direction and avoids the problem of the carton not entering the sealing machine in the correct direction due to conveying errors, parallelism errors, slippage, etc., caused by the conveying mechanism located at the bottom. This ensures the sealing quality and solves the defect in the background technology where the carton cannot enter the sealing machine in the correct direction, resulting in offset during sealing and poor sealing effect.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are partial embodiments of this utility model, not embodiments of the entire utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Please refer to Figures 1 to 4A side sealing structure for a carton includes a pressing part 1, a support 2, a transmission part 3, and an auxiliary part 4. The pressing part 1 is located at the bottom end of the transmission part 3. Both the pressing part 1 and the transmission part 3 are slidably connected to the support 2. The transmission part 3 drives the pressing part 1 to move up and down in the vertical direction. The auxiliary part 4 is located at the front end of the pressing part 1. The pressing part 1 includes a pressing block 11. The auxiliary part 4 includes a first guide rod 41. The first guide rod 41 is connected to the pressing block 11. The first guide rod 41 can change the direction of the carton and transport it to the bottom end of the pressing block 11.

[0025] In this technical solution, the side sealing structure is located in the sealing machine on the carton conveying mechanism. The side sealing structure is perpendicular to the carton conveying mechanism. The transmission part 3, support 2, and pressing part 1 of the side sealing structure are connected sequentially from top to bottom. The auxiliary part 4 is located at the front end of the pressing part and is positioned opposite to the carton conveying direction. The transmission part 3 and the pressing part 1 are connected by the support 2. The transmission part 3 can drive the support 2 to slide, allowing the support 2 to drive the pressing part 1 to move up and down in the vertical direction of the sealing machine. The auxiliary part 4 is positioned opposite to the carton conveying direction. The first guide rod 41 of the auxiliary part 4 is connected to the pressing block 11 of the pressing part 1. When the carton is conveyed to the sealing machine along the conveying mechanism, the sealing machine pushes... The moving mechanism pushes the carton into the side sealing structure. The transmission unit 3 drives the pressing part 1 to move up and down in the vertical direction. However, the conveying mechanism continues to convey the carton. The pressing part 1 moves downward, and the first guide rod 41 intercepts the carton. After the carton is intercepted, it comes into contact with the pushing mechanism of the sealing machine. The pushing mechanism of the sealing machine continues to push the carton, causing the carton to change direction and move towards the bottom of the pressing block 11. This achieves the reversal of the carton's direction and avoids the problem of the carton not entering the sealing machine in the correct direction due to the conveying error, parallelism error, slippage, etc. of the conveying mechanism located at the bottom. This ensures the sealing quality and solves the defect in the background technology that the carton cannot enter the sealing machine in the correct direction, resulting in offset during sealing and poor sealing effect.

[0026] Preferably, by Figure 1 and Figure 2 As shown, the auxiliary part 4 is provided with two first guide rods 41, which are arranged in parallel and their lengths extend to both sides of the pressing block 11, thereby increasing the interception function and making the carton less likely to be punctured.

[0027] Further from Figure 1 and Figure 2As shown, the auxiliary part 4 also includes a second guide rod 42, which is located beside the first guide rod 41. The height of the second guide rod 42 in the vertical direction is lower than that of the first guide rod 41. In this embodiment, the second guide rod 42 is fixedly connected to the wall of the carton sealing machine, and the position of the second guide rod 42 is controlled by an angle adjustment mechanism. Alternatively, the outer side of the pressing block 11 can be extended outward to form the second guide rod 42. The installation method of the second guide rod 42 is not limited, and its installation method is a conventional technical means, which will not be described in detail here. However, the second guide rod 42 can always be kept beside the two first guide rods 41 to enhance the interception of the carton. At the same time, because the height of the second guide rod 42 is slightly lower than that of the first guide rod 41, when the carton is intercepted by the first guide rod 41 and the second guide rod 42, the height difference between the first guide rod 41 and the second guide rod 42 will hold the corner of the carton, so that the tape can adhere to the corner of the carton. To further explain, both the first guide rod 41 and the second guide rod 42 are provided with an abutment section 400. The abutment section is arranged in an arc shape and is set upward, which reduces friction and contact with the carton and effectively reduces the risk of the carton being scratched or punctured by the auxiliary part 4, thus affecting the appearance of the carton.

[0028] The specific assembly relationship between the pressing part 1 and the bracket 2 is as follows: Figure 1 and Figure 2As shown, the pressing part 1 also includes a sliding plate 12, which is fixedly installed on the pressing block 11. The pressing block 11 is used to press down the carton so that the tape can adhere to the carton. A first slide rail 21 is provided on one side of the bracket 2, and the sliding plate 12 is matched and connected to the first slide rail 21. In this embodiment, the slide rail 12 is vertically fixedly connected to the pressing block 11, and the first slide rail 21 is provided on one side of the bracket 2. The sliding plate 12 moves up and down adaptively along the length of the first slide rail 21 so that the pressing block 11 can press down the carton. The user can flexibly change the height position of the pressing part 1 according to the size of the carton. Specifically, the pressing part 1 and the bracket 2 are connected by a driving cylinder 5, and the two ends of the driving cylinder 5 are respectively connected and fixed to the sliding plate 12 and the bracket 2. When the transmission unit 3 drives the bracket 2 to move upward, the drive cylinder 5 is in a compressed state, applying an upward force to the pressing edge part 1, allowing the sliding plate 12 of the pressing edge part 1 to move upward along the length direction of the first slide rail 21 of the bracket 2. When the transmission unit 3 drives the bracket 2 to move downward, the drive cylinder 5 is in a stretched state, applying a downward force to the pressing edge part 1, allowing the sliding plate 12 of the pressing edge part 1 to move downward along the length direction of the first slide rail 21 of the bracket 2. Preferably, the drive cylinder 5 is a stretching cylinder, which mainly consists of a cylinder barrel, piston, piston rod, front and rear end caps, and seals. During the operation of the stretching cylinder, compressed air enters the cylinder through the air hole, pushing the piston to move, thereby causing the piston rod to extend or retract. When compressed air enters the rodless chamber of the stretching cylinder, pressure acts on the piston, pushing the piston outward and causing the piston rod to extend. The stretching cylinder is a conventional technical means and will not be described in detail here.

[0029] The specific assembly relationship between the transmission part 3 and the bracket 2 is as follows: Figures 2 to 4As shown, the transmission unit 3 includes a mounting frame 31, which is provided with a sliding rod 311. A second slide rail 22 is provided on the other side of the bracket 2, and the sliding rod 311 is matched and connected to the second slide rail 22. When the transmission unit 3 is driven, the sliding rod 311 reciprocates up and down along the length of the second slide rail 22 of the bracket 2. Specifically, the transmission unit 3 also includes a drive motor 32 and a sprocket transmission mechanism 33. The drive motor 32 is fixedly mounted on the mounting frame 31 and connected to the sprocket transmission mechanism 33. A connecting plate 23 is provided at the top of the slide plate 12, and both ends of the sprocket transmission mechanism 33 are connected to the connecting plate 23. In this embodiment, the drive motor 32 is fixedly mounted on the mounting bracket 31, and the sliding rod 311 of the mounting bracket 31 moves up and down along the length of the bracket 2. The other side of the bracket 2 is slidably connected to the sliding plate 12 of the pressing edge part 1. Both ends of the sprocket transmission mechanism 33 are connected to the connecting plate 23. When the drive motor 32 drives the sprocket transmission mechanism 33 to operate, the sprocket transmission mechanism 33 drives the bracket 2 to move up and down. The drive cylinder 5 is activated to assist the bracket 2 in moving up and down, thereby driving the pressing edge part 1 to move up and down. Specifically, this is achieved by... Figure 4 As shown. When the drive motor 32 starts, the sprocket transmission mechanism 33 uses the meshing of the chain and sprocket teeth to transmit power and drive the rotation. The second slide rail 22 of the bracket 2 can move up and down along the length of the sliding rod 311. Then, the drive cylinder 5 drives the slide plate 12 of the pressing part 1 to move synchronously, realizing the height adjustment of the pressing block 11 of the pressing part 1 to adapt to different carton sizes. There is no need for the drive motor 32 to move together, which increases the service life of the drive motor 32. The sprocket transmission mechanism 33 is a conventional technical means and will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
