Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging box processing, in particular to an automatic bonding device for paper packaging box processing. Background Technique

[0002] Paper packaging boxes are a widely used packaging solution, mainly used to protect and transport various products. During the processing of paper packaging boxes, the automatic bonding device plays a crucial role. It can continuously and stably perform the bonding operation in a high-speed production line, reducing the dependence on manual labor and lowering the labor cost. However, after the bonding is completed, a pressing step is usually required to ensure the firmness of the bonding part and the overall packaging quality, preventing loosening or cracking during transportation and handling.

[0003] The traditional automatic bonding device for paper packaging boxes usually places the paper packaging box to be pressed in the pressing area after the bonding area, and then starts the electric push rod. The telescopic end of the electric push rod pushes the pressing plate forward to make the pressing plate contact the packaging box. At this time, the action of the electric push rod will push the pressing plate to apply uniform pressure. After the pressing is completed, the electric push rod automatically retracts to release the pressure on the packaging box.

[0004] The traditional automatic bonding device for paper packaging boxes has the following problems: The electric push rod is prone to unstable power supply voltage, which makes the movement of the push rod unstable or intermittent. This instability will affect the downward pressing process of the push rod, resulting in discontinuous actions, making the bonding quality of each cardboard box inconsistent, requiring more time to process each cardboard box, and reducing the production efficiency. For this reason, we propose an automatic bonding device for paper packaging box processing. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic bonding device for paper packaging box processing, which can realize a relatively high continuity of pressing the paper packaging box, making the pressing force received by each cardboard box more uniform and consistent, which greatly improves the consistency of the bonding quality of the cardboard box and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: An automatic bonding device for paper packaging box processing, including an electric conveyor belt and a pressing mechanism;

[0007] Electric conveyor belt: The front and rear ends of its upper surface are respectively fixedly connected with mounting frames, and the tops of the mounting frames are fixedly connected with the lower surface of an installation shell;

[0008] Pressing mechanism: It includes a connecting rod, a rotating shaft, a cam and a lower pressing plate. The rotating shaft is rotatably connected between the left and right inner walls of the installation housing. A cam is fixedly sleeved in the middle of the rotating shaft. The connecting rod is slidably connected in the sliding opening on the lower surface of the installation housing. The bottom end of the connecting rod is fixedly connected with the lower pressing plate. The lower pressing plate slides vertically between the inner sides of the installation frame. The top end of the connecting rod is cooperatively installed with the cam;

[0009] Among them: It also includes a single-chip microcomputer. The single-chip microcomputer is arranged at the right end of the front side of the electric conveyor belt. The output end of the single-chip microcomputer is electrically connected to the input end of the electric conveyor belt, which can realize the pressing of paper packaging boxes with high continuity, making the pressing force received by each carton more uniform and consistent. This greatly improves the consistency of the carton bonding quality and significantly improves the production capacity and the utilization rate of the production line.

[0010] Furthermore, it also includes support legs. The support legs are fixedly connected to the front and rear ends of the lower surface of the electric conveyor belt respectively, which is convenient for supporting the stable transportation of the electric conveyor belt.

[0011] Furthermore, the pressing mechanism also includes an avoidance groove. The avoidance groove is opened at the rear end of the cam. The avoidance groove is cooperatively installed with the connecting rod to ensure the accurate return of the cam during rotation.

[0012] Furthermore, the pressing mechanism also includes a first spring, a support rod and a sliding groove. The sliding grooves are respectively opened on the inner sides of the installation frame. Support rods are fixedly connected between the upper and lower inner walls of the sliding grooves. The middle parts of the support rods are slidably connected to the adjacent ends of a lower pressing plate. First springs are fixedly connected between the left and right ends of the upper surface of the lower pressing plate and the top walls of the adjacent sliding grooves. The first springs are sleeved on the outer surfaces of the support rods respectively, which can ensure accurate return to the predetermined position through the continuity of pressing.

[0013] Furthermore, the pressing mechanism also includes a motor. The motor is installed on the right side of the installation housing through bolts. The left end of the output shaft of the motor is fixedly connected to the right end of the rotating shaft. The input end of the motor is electrically connected to the output end of the single-chip microcomputer to drive the pressing mechanism.

[0014] Furthermore, it also includes an elastic pressing plate mechanism. The elastic pressing plate mechanism includes sliding columns, sliding holes, a pressing plate and rubber pads. The sliding holes are respectively opened at the four corners of the lower surface of the lower pressing plate. The inner walls of the sliding holes are slidably connected with the sliding columns. The bottom ends of the sliding columns are fixedly connected to the four corners of the upper surface of a pressing plate. Rubber pads are arranged on the lower surface of the pressing plate for the sliding limit of the pressing plate.

[0015] Furthermore, the elastic pressing plate mechanism also includes a second spring. The second springs are fixedly connected between the four corners of the upper surface of the pressing plate and the adjacent ends of the lower surface of the lower pressing plate respectively. The second springs are sleeved on the outer surfaces of the sliding columns respectively, which can self-adjust the pressing force to ensure uniform applied pressure.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The automatic bonding device for processing paper packaging boxes has the following advantages:

[0017] The motor is controlled by a single-chip microcomputer. The rotation of the motor drives the rotation of the cam. The cam pushes the connecting rod, and then the lower pressing plate drives the rubber pad on the pressing plate to apply pressure to the paper packaging box. During the downward pressing process, the first spring stretches to store energy, and the pressing plate self-adjusts the pressing force through the sliding hole and the compression of the second spring to ensure that the applied pressure is uniform, thus avoiding over-pressing or under-pressing during the pressing process. After the cam rotation is completed, the first spring and the second spring return to their original positions, driving the lower pressing plate and the pressing plate back to the initial position. Therefore, the continuous pressing action of the pressing plate can be controlled by the cam to ensure that the bonding quality of each paper packaging box is consistent and improve production efficiency.

Place the glued paper packaging box at the left starting point of the electric conveyor belt 2 and prepare to enter the pressing area. Control the operation of the electric conveyor belt 2 through the single-chip microcomputer 7. The electric conveyor belt 2 starts to run, transports the paper packaging box from the starting point to the pressing area. After pressing is completed, control the electric conveyor belt 2 to start again through the single-chip microcomputer 7, move the pressed paper packaging box to the right end point, and a new paper packaging box enters the pressing area, and repeat the above steps for pressing;

[0026] Pressing mechanism 3: It includes a connecting rod 31, a rotating shaft 34, a cam 35 and a lower pressing plate 37. The rotating shaft 34 is rotatably connected between the left and right inner walls of the mounting housing 4. A cam 35 is fixedly sleeved in the middle of the rotating shaft 34. The connecting rod 31 is slidably connected in the sliding opening on the lower surface of the mounting housing 4. The bottom end of the connecting rod 31 is fixedly connected with a lower pressing plate 37. The lower pressing plate 37 slides vertically between the inner sides of the mounting frame 5. The top end of the connecting rod 31 is cooperatively installed with the cam 35. It also includes an elastic pressing plate mechanism 6. The elastic pressing plate mechanism 6 includes sliding columns 61, sliding holes 62, a pressing plate 64 and rubber pads 65. The sliding holes 62 are respectively opened at the four corners of the lower surface of the lower pressing plate 37. The inner walls of the sliding holes 62 are all slidably connected with sliding columns 61. The bottom ends of the sliding columns 61 are fixedly connected with the four corners of the upper surface of a pressing plate 64. Rubber pads 65 are provided on the lower surface of the pressing plate 64. The elastic pressing plate mechanism 6 also includes second springs 63. The second springs 63 are fixedly connected between the four corners of the upper surface of the pressing plate 64 and the adjacent ends of the lower surface of the lower pressing plate 37. The second springs 63 are all sleeved on the outer surfaces of the sliding columns 61. The pressing mechanism 3 also includes an avoidance groove 33. The avoidance groove 33 is opened at the rear end of the cam 35. The avoidance groove 33 is cooperatively installed with the connecting rod 31. The pressing mechanism 3 also includes first springs 36, support rods 38 and sliding grooves 39. The sliding grooves 39 are respectively opened on the inner sides of the mounting frame 5. Support rods 38 are fixedly connected between the upper and lower inner walls of the sliding grooves 39. The middle parts of the support rods 38 are slidably connected with the adjacent ends of a lower pressing plate 37. First springs 36 are fixedly connected between the left and right ends of the upper surface of the lower pressing plate 37 and the top walls of the adjacent sliding grooves 39. The first springs 36 are all sleeved on the outer surfaces of the support rods 38. The pressing mechanism 3 also includes a motor 32. The motor 32 is installed on the right side of the mounting housing 4 by bolts. The left end of the output shaft of the motor 32 is fixedly connected with the right end of the rotating shaft 34. The input end of the motor 32 is electrically connected to the output end of the single-chip microcomputer 7. When the paper packaging box reaches the predetermined pressing area, the single-chip microcomputer 7 controls the electric conveyor belt 2 to stop running. At this time, the paper packaging box is stationary in the pressing area and is ready for pressing operation. By controlling the motor 32 to operate through the single-chip microcomputer 7, the output shaft of the motor 32 drives the rotating shaft 34 to rotate. The rotating shaft 34 drives the cam 35 to rotate, so that its eccentric end contacts the top end of the connecting rod 31, applying a downward extrusion force. The connecting rod 31 is subjected to the extrusion force applied by the cam 35 and pushes the lower pressing plate 37 and the pressing plate 64 to move in the sliding groove 39 along the axis of the support rod 38. During the downward pressing process, the first spring 36 is stretched and stores a certain amount of elastic potential energy. At the same time, the rubber pad 65 on the pressing plate 64 contacts the paper packaging box and applies an extrusion force to it. The pressing plate 64 slides on the inner wall of the sliding hole 62 and compresses the second spring 63. The second spring 63 plays a role in adaptively adjusting the pressing force to prevent over-pressing or under-pressing during the pressing process. As the cam 35 continues to rotate, the eccentric end cancels contact with the connecting rod 31. At this time, the first spring 36 and the second spring 63 recover their elasticity and push the connecting rod 31 back into the avoidance groove 33 on the cam 35.The resilience of spring one 36 and spring two 63 brings the lower pressing plate 37 and the pressing plate 64 back to the initial position, preparing for the next pressing. However, the continuity of pressing is limited by the rotational speed of the cam 35. Increasing the speed can increase the pressing frequency.

[0027] Among them: It also includes a single-chip microcomputer 7. The single-chip microcomputer 7 is arranged at the right end of the front side of the electric conveyor belt 2. The output end of the single-chip microcomputer 7 is electrically connected to the input end of the electric conveyor belt 2. The operating speed and time of the electric conveyor belt 2 are precisely controlled by the single-chip microcomputer 7 according to the production rhythm.

[0028] The working principle of an automatic bonding device for paper packaging box processing provided by the present utility model is as follows: First, place the bonded paper packaging box at the left starting point of the electric conveyor belt 2 and prepare to enter the pressing area. Control the operation of the electric conveyor belt 2 through the single-chip microcomputer 7. The electric conveyor belt 2 starts to run and conveys the paper packaging box from the starting point to the pressing area. However, the operating speed and time of the electric conveyor belt 2 are precisely controlled by the single-chip microcomputer 7 according to the production rhythm. When the paper packaging box reaches the predetermined pressing area, the single-chip microcomputer 7 controls the electric conveyor belt 2 to stop running. At this time, the paper packaging box is stationary in the pressing area and prepares for the pressing operation. Control the operation of the motor 32 through the single-chip microcomputer 7. The output shaft of the motor 32 drives the rotating shaft 34 to rotate. The rotating shaft 34 drives the cam 35 to rotate, making its distal end contact the top of the connecting rod 31 and applying a downward extrusion force. The connecting rod 31 is subjected to the extrusion force applied by the cam 35 and pushes the lower pressing plate 37 and the pressing plate 64 to move along the axis of the support rod 38 in the sliding groove 39. During the downward pressing process, spring one 36 is stretched and stores a certain amount of elastic potential energy. At the same time, the rubber pad 65 on the pressing plate 64 contacts the paper packaging box and applies an extrusion force to it. The pressing plate 64 slides on the inner wall of the sliding hole 62 and compresses spring two 63. Spring two 63 plays a role in adaptively adjusting the pressing force to prevent over-pressing or under-pressing during the pressing process. As the cam 35 continues to rotate, the distal end cancels contact with the connecting rod 31. At this time, spring one 36 and spring two 63 recover their elasticity and push the connecting rod 31 back into the avoidance groove 33 on the cam 35. The resilience of spring one 36 and spring two 63 brings the lower pressing plate 37 and the pressing plate 64 back to the initial position, preparing for the next pressing. However, the continuity of pressing is limited by the rotational speed of the cam 35. Increasing the speed can increase the pressing frequency. After pressing is completed, control the electric conveyor belt 2 to start again through the single-chip microcomputer 7, move the pressed paper packaging box to the right end point, and a new paper packaging box enters the pressing area and repeats the above steps for pressing.

[0029] It should be noted that the specific model of the single-chip microcomputer 7 disclosed in the above embodiments is S7-200. For the electric conveyor belt 2, it is recommended to select dl-1132, and for the motor 32, Y180L-615 can be selected. The single-chip microcomputer 7 controls the operation of the electric conveyor belt 2 and the motor 32 by using the commonly used methods in the prior art.

[0030] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
