Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically a flip-type baffle suitable for carton side sealing equipment. Background Technology

[0002] The working process of fully automatic carton side sealing equipment (such as carton gluing machines and carton nailing machines) includes paper feeding, paper positioning, side sealing, sorting and output. The entire process is completed through the cooperation of a precise control system and actuators, thereby achieving a highly efficient and accurate carton side sealing production process.

[0003] A double-sheet carton side sealing machine is a specialized device for sealing the sides of two sheets of paper, A and B. The workpiece is transported via a belt conveyor. Once the workpiece is conveyed to the side sealing station, the front end of the paper sheet is first positioned, then the ends are aligned and the sides are pressed together. Finally, the sealing area is connected by gluing or binding. During this process, the front-end positioning uses a stop gauge to switch between blocking and releasing the workpiece. Furthermore, the stop gauge needs to be adjusted forward and backward for different sizes of paper sheets. To ensure the accuracy of the front-end positioning, the stop gauge structure needs to be optimized. Utility Model Content

[0004] This utility model provides a flip-type baffle suitable for carton side sealing equipment. It aims to match paper workpieces of different specifications and sizes by optimizing the front and rear position adjustment mechanism and the eccentric crank flip mechanism of the baffle, and realize the conversion between the blocking and releasing states of the baffle on the workpiece, so as to ensure the accuracy of the front end positioning of the workpiece and improve the sealing quality of the carton side.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flip-type baffle suitable for carton side sealing equipment, equipped with a baffle front and rear position adjustment mechanism and an eccentric crank flip-type mechanism;

[0007] The front and rear position adjustment mechanism of the guide rail is installed on the wall panel of the sealing equipment on the side of the carton. It includes an adjustment motor, a lead screw and nut assembly and a movable seat. The adjustment motor drives the lead screw to rotate to realize the movement of the nut in the front and rear direction. The movable seat is fixedly assembled on the nut.

[0008] The eccentric crank flap mechanism includes a main motor, an eccentric wheel, a main swing arm, a small swing arm, and a baffle. The main motor is mounted on the movable seat of the gauge front and rear position adjustment mechanism. The central axis of the main motor is perpendicular to the central axis of the lead screw. The eccentric wheel is mounted on the output shaft of the main motor. One end of the main swing arm is rotatably fitted over the eccentric wheel, and the other end of the main swing arm is assembled with the small swing arm. L-shaped connecting seats are provided at both ends of the small swing arm. The horizontal arm of one end of the L-shaped connecting seat is hinged to the main swing arm, and the vertical arm of the L-shaped connecting seat is fitted with the movable seat of the gauge front and rear position adjustment mechanism through a rotating shaft. The baffle includes two parts arranged on the left and right sides, and the baffle is fixed on the vertical arms of the L-shaped connecting seats at both ends of the small swing arm.

[0009] The aforementioned flip-type baffle, suitable for carton side sealing equipment, has a servo motor in both the adjusting motor of the baffle front and rear position adjustment mechanism and the main motor of the eccentric crank flip mechanism.

[0010] The aforementioned flap-type stop, suitable for carton side sealing equipment, has a bearing assembled between the main swing rod and the eccentric wheel of the eccentric crank flap mechanism.

[0011] The aforementioned flip-type baffle suitable for carton side sealing equipment, wherein the baffle front and rear position adjustment mechanism is further provided with a guide component, the guide component including a guide slide shaft and a guide slide sleeve; the two ends of the guide slide shaft are fixed on the front and rear support seats of the carton side sealing equipment wall panel, and the guide slide sleeve is fixedly assembled with the movable seat and fitted outside the guide slide shaft.

[0012] This invention provides a flip-plate type stop suitable for carton side sealing equipment. Utilizing the dead-point structure of an eccentric crank flip-plate mechanism, the stop is vertical when the main motor reaches the dead-point position, achieving both blocking and reliable front-end positioning of the paper, ensuring the accuracy of rear-end alignment, side-side pressing, and side sealing. After completing the side sealing, the main motor rotates a set angle, releasing the dead-point of the eccentric crank flip-plate mechanism, and the stop flips at a certain angle, providing clearance for the paper and allowing the workpiece to pass. This invention also includes a stop-plate front-to-back position adjustment mechanism to accommodate paper workpieces of different sizes. In summary, through optimized design of the stop-plate front-to-back position adjustment mechanism and the eccentric crank flip-plate mechanism, this invention can accommodate paper workpieces of different sizes and achieves the switching between blocking and releasing states of the stop, thereby ensuring the accuracy of workpiece front-end positioning and improving the quality of carton side sealing.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] See Figure 1. Figure 2This utility model provides a flip-type stop gauge suitable for carton side sealing equipment, especially for fully automatic carton stapling machines in the carton production process. A double-sheet carton stapling machine is a device specifically designed to seal the sides of two sheets of paper, A and B. The workpiece is transported via belt conveyor. After the workpiece is transported to the stapling station, the front end of the paper sheet is positioned, the rear end is aligned, and both sides are pressed tightly. Then, the sealed parts of the paper sheets are connected by stapling. During this process, the front end positioning is achieved through a stop gauge, which controls the switching between blocking and releasing states of the workpiece. Furthermore, the stop gauge needs to be adjusted forward and backward for different sizes of paper workpieces. To match different sizes of paper workpieces and achieve the switching between blocking and releasing states, this utility model includes a stop gauge forward and backward position adjustment mechanism 1 and an eccentric crank flip-plate mechanism 2. The stop gauge forward and backward position adjustment mechanism 1 is installed on the wall panel 3 of the carton side sealing equipment, and the eccentric crank flip-plate mechanism 2 is fitted with the stop gauge forward and backward position adjustment mechanism 1.

[0029] See Figure 3 , Figure 4 The front and rear position adjustment mechanism 1 of this utility model includes an adjustment motor 1-1, a lead screw and nut assembly, a movable seat 1-4, and a guide assembly. The adjustment motor 1-1 drives the lead screw 1-2 to rotate, thereby moving the nut 1-3 in the front and rear direction. The movable seat 1-4 is fixedly mounted on the nut 1-3. The guide assembly includes a guide slide shaft 1-5 and a guide sleeve 1-6. The two ends of the guide slide shaft 1-5 are fixed to the front and rear support seats 3-1 of the side sealing device wall panel 3 of the carton. The guide sleeve 1-6 is fixedly mounted to the movable seat 1-4 and is fitted over the guide slide shaft 1-5.

[0030] See Figure 5 , Figure 6 , Figure 7 The eccentric crank flap mechanism 2 of this utility model includes a main motor 2-1, an eccentric wheel 2-2, a main swing rod 2-3, a small swing rod 2-4, and a baffle 2-5. The main motor 2-1 is mounted on the movable seat 1-4 of the front and rear position adjustment mechanism 1 of the stop gauge, and its central axis is perpendicular to the central axis of the lead screw 1-2. The eccentric wheel 2-2 is mounted on the output shaft of the main motor 2-1. One end of the main swing rod 2-3 is rotatably fitted outside the eccentric wheel 2-2. The main swing rod 2-3 and the eccentric wheel 2-2 cooperate to form a crank-connecting rod structure. A bearing 2-7 is assembled between the main swing rod 2-3 and the eccentric wheel 2-2, and the other end of the main swing rod 2-3 is assembled with the small swing rod 2-4; L-shaped connecting seats are provided at both ends of the small swing rod 2-4, and the horizontal arm of one end of the L-shaped connecting seat is hinged to the main swing rod 2-3. The vertical arm of the L-shaped connecting seat is fitted with the moving seat 1-4 of the stop gauge front and rear position adjustment mechanism 1 through the rotating shaft 2-6. The baffle 2-5 includes two parts arranged on the left and right, and the baffle 2-5 is fixed on the vertical arm of the L-shaped connecting seat at both ends of the small swing rod 2-4.

[0031] See Figure 2 , Figure 4 , Figure 8 The flip-type baffle, suitable for carton side sealing equipment, as described in this utility model, adjusts the front and rear positions of the baffle through the baffle front and rear position adjustment mechanism 1 to accommodate paper workpieces of different sizes. During the operation of the fully automatic carton stapler, when the paper workpiece is conveyed to the binding station, the main motor 2-1 rotates to the dead point position of the eccentric crank flip mechanism 2. At this time, the baffle is in a vertical state. Since the eccentric crank flip mechanism 2 is in a dead point state, the impact force of the paper workpiece 4 cannot cause the baffle 2-5 to flip. This achieves the blocking effect of the baffle 2-5 on the paper workpiece 4 and reliable positioning of the front end, ensuring the accuracy of rear end alignment, side pressing, and side binding operations. After the side binding operation is completed, the main motor 2-1 rotates by a set angle α, the dead point state of the eccentric crank flip mechanism 2 is released, and the baffle 2-5 flips by a certain angle, allowing the paper workpiece 4 to pass through the clearance space and realize the release of the workpiece.
