Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, specifically a two-piece alignment calibration device for a three-dimensional two-piece nailing machine. Background Technology

[0002] A carton stapler is one of the finishing processes for cardboard boxes. Its principle is the same as that of a regular stapler, except that it uses a toothed plate as a backing plate, specifically for sealing cardboard boxes. A search reveals that Chinese Patent Publication No. CN116330736A discloses a correction mechanism for a double-plate carton stapler, belonging to the field of packaging technology. It includes: a frame, a first conveying component, a longitudinal drive component, a lifting drive component, and a correction plate. The first conveying component is rotatably connected to the frame; the longitudinal drive component is fixed to the inner top of the frame, and its drive end can reciprocate along the front and rear ends of the frame; the lifting drive component is fixed to the drive end of the longitudinal drive component, and its drive end can reciprocate up and down; the correction plate is fixed to the drive end of the lifting drive component.

[0003] The above technical solution can correct paper during transportation by fixing the correction plate to the drive end of the lifting drive assembly. However, the rigid contact between the correction plate and the paper can easily cause damage to the paper edges. The longitudinal drive assembly adopts a crank-connecting rod structure, which is not accurate enough when running at high speed. The length of the correction plate is fixed, which cannot be adapted to paper of different widths, thus affecting the correction effect. Utility Model Content

[0022] like Figure 1 and Figure 2As shown, a two-piece alignment and correction device for a three-dimensional two-piece nailing machine includes two mounting plates 1 fixedly installed on the frame of the three-dimensional two-piece nailing machine. A first servo motor 2 is installed on one side of any one of the mounting plates 1. The output shaft of the first servo motor 2 is fixedly connected to a first lead screw 3 rotatably connected to the two mounting plates 1. A first mounting seat 4 is threadedly connected to the outer surface of the first lead screw 3. A first guide rod 7 is fixedly connected between the two mounting plates 1. The first guide rod 7 is slidably connected to the inside of the first mounting seat 4. A longitudinal moving mechanism 5 is installed on the outer surface of the first mounting seat 4. The rotation of the first servo motor 2 drives the first lead screw 3 to rotate, and the first mounting seat 4 can be moved through the thread, which can change the lateral position of the correction mechanism 6.

[0023] like Figure 1 and Figure 2 As shown, the longitudinal movement mechanism 5 includes a second lead screw 51 rotatably connected to the first mounting base 4 via a bearing. The outer surface of the second lead screw 51 is threadedly connected to a second mounting base 52, which is slidably connected to the outer surface of the first mounting base 4. The correction mechanism 6 is mounted on the second mounting base 52. A second servo motor 53 for driving the second lead screw 51 to rotate is fixedly mounted on the top of the first mounting base 4. Two slide rails 54 are symmetrically fixedly connected to one side of the outer surface of the first mounting base 4, and the second mounting base 52 is slidably connected to the two slide rails 54.

[0024] The rotation of the second servo motor 53 drives the rotation of the second lead screw 51. With the cooperation of the threaded slide rail 54, the second mounting base 52 and the correction mechanism 6 can move up and down, changing the longitudinal position of the correction mechanism 6. The combination of servo motor and lead screw can improve the adjustment accuracy and meet the needs of high-speed operation.

[0025] like Figures 1 to 4 As shown, a correction mechanism 6 for aligning and correcting the two pieces is installed on the outer surface of the longitudinal moving mechanism 5. The correction mechanism 6 includes a cylinder 61 fixedly installed on the second mounting base 52. A U-shaped frame 62 is fixedly connected to the bottom end of the cylinder 61. A main baffle 63 is fixedly connected to the bottom end of the U-shaped frame 62. A secondary baffle 64 is provided on both sides of the main baffle 63. A silicone buffer plate 65 is glued to one side of the outer surface of the main baffle 63 and the secondary baffle 64.

[0026] When aligning and correcting the carton, the cylinder 61 moves the U-shaped frame 62 downward, which in turn moves the main baffle 63 and the secondary baffle 64 downward, thereby blocking and aligning one side of the carton. When the carton touches the main baffle 63 or the secondary baffle 64, the silicone buffer plate 65 can cushion and protect the carton, avoiding damage caused by rigid contact.

[0027] A third servo motor 66 is fixedly mounted on the top of the main baffle 63. A gear 67 is fixedly connected to the output shaft of the third servo motor 66. Two racks 68, which are symmetrically meshed with the outer surface of the gear 67 and are slidably connected to the U-shaped frame 62, are respectively fixedly connected to the top of the corresponding auxiliary baffle 64. Two second guide rods 69 are symmetrically fixedly connected to one side of the auxiliary baffle 64. The second guide rods 69 are slidably connected to the inside of the main baffle 63.

[0028] Before use, the third servo motor 66 can be started according to the width of the carton. The rotation of the third servo motor 66 drives the gear 67 to rotate. With the cooperation of the two racks 68, the auxiliary baffles 64 on both sides can be moved to both sides, which can adjust the length of the entire blocking alignment part to adapt to different widths of paper and ensure full width correction.

[0029] It should be noted that this technical solution also includes a controller, which can be installed on the mounting plate or the frame of the three-dimensional double-piece nailing machine. The controller facilitates the control of the first servo motor 2, the second servo motor 53, the third servo motor 66 and the cylinder 61. Controlling by a controller is a common technical means used by those skilled in the art and belongs to the prior art.

[0030] Working principle: When in use, the device is installed on the frame of the three-dimensional double-piece nailing machine through the mounting plate 1, so that the correction mechanism 6 corresponds to the moving direction of the carton. The first servo motor 2 rotates and drives the first lead screw 3 to rotate. Through the thread, the first mounting base 4 can be moved, which can change the lateral position of the correction mechanism 6.

[0031] The rotation of the second servo motor 53 drives the rotation of the second lead screw 51. With the cooperation of the threaded slide rail 54, the second mounting base 52 and the correction mechanism 6 can move up and down, changing the longitudinal position of the correction mechanism 6. The combination of servo motor and lead screw can improve the adjustment accuracy and meet the needs of high-speed operation.

[0032] When aligning and correcting the carton, the cylinder 61 moves the U-shaped frame 62 downward, which in turn moves the main baffle 63 and the secondary baffle 64 downward, thereby blocking and aligning one side of the carton. When the carton touches the main baffle 63 or the secondary baffle 64, the silicone buffer plate 65 can cushion and protect the carton, avoiding damage caused by rigid contact.

[0033] Before use, the third servo motor 66 can be started according to the width of the carton. The rotation of the third servo motor 66 drives the gear 67 to rotate. With the cooperation of the two racks 68, the auxiliary baffles 64 on both sides can be moved to both sides, which can adjust the length of the entire blocking alignment part to adapt to different widths of paper and ensure full width correction.

[0034] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
