[0025] The technical solution of the present invention is further described in detail below through specific embodiments in combination with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way. The accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding and are not intended to limit the present invention in any way.

[0026] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of the present invention. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0027] As described in the background technology, the existing carton stitching machine is not convenient for adjusting the position of the positioning plate at the conveying head end during use, resulting in that when stapling cartons of different sizes, it is difficult to position them due to the different sizes of the cardboards, resulting in the position of the nailing box cannot be fixed and affecting the accuracy of the nailing box.

[0028] For the reasons mentioned above, please refer to the attached Figure 1 -Attached Figure 2 The utility model provides a carton stapling device which is convenient for positioning and conveying, comprising a conveying frame 1, two parallel conveying belts 2 are arranged inside and a gap is maintained between the conveying belts 2;

[0029] The guide mechanism is movably arranged at the conveying front end of the conveying frame 1;

[0030] The pressing mechanism is arranged above the conveying frame 1 and corresponds to the conveyor belt 2;

[0031] The box stapling mechanism is arranged above the conveying frame 1 and performs a box stapling operation on the cardboard being conveyed through the pressing mechanism.

[0032] Specifically, side baffles 3 are provided at both ends of the top of the conveying frame 1 , and the guiding mechanism, the pressing mechanism and the nailing box mechanism are all installed on the side baffles 3 across the conveyor belt 2 .

[0033] Specifically, the clamping mechanism includes two rollers 4 arranged above the conveying frame 1 and kept parallel, and two clamping belts 5 tensioned between the rollers 4. The clamping belts 5 are consistent with the conveying direction of the conveyor belt 2 and are located directly above the conveyor belt 2.

[0034] Furthermore, the roller is rotatably mounted above the side baffle and is driven to rotate by a driving motor.

[0035] Specifically, the conveying speeds of the conveying belt 2 and the pressing belt 5 are consistent and their conveying directions are adapted to each other.

[0036] Specifically, the nailing mechanism includes a door-shaped support frame 6 and a nailing machine head 8 telescopically arranged on the door-shaped support frame 6. The door-shaped support frame 6 spans the conveyor belt 2 and is fixed on the side baffle 3. A linear telescopic device 7 is provided on the door-shaped support frame 6. The telescopic end of the linear telescopic device 7 passes vertically downward through the gap between the door-shaped support frame 6 and the two compression belts 5. The nailing mechanism 8 is fixed on the telescopic end of the linear telescopic device 7.

[0037] Furthermore, the linear telescopic device can be configured as an existing air cylinder, electric push rod, etc. that is easy to automatically control and has a fast telescopic speed, so as to facilitate the rapid nailing operation. The nailing machine head is composed of the head of an existing conventional nailing machine, which can realize the functions of automatic nailing and automatic loading of nails. A visual sensor is also installed at the nailing mechanism position. When it senses that there is cardboard below, it automatically sends a signal to the external PLC control system to control the nailing mechanism and the linear telescopic device to move once, and perform a nailing operation. This method is the conventional working method of the existing nailing machine and will not be repeated here.

[0038] Please refer to the attached Figure 4 Specifically, strip holes parallel to the conveying direction are opened on the top of both sides of the conveying head end of the conveying frame body 1, and the guide mechanism is movably installed on the strip holes and the side baffles 3.

[0039] Please continue to refer to the attached Figure 4Specifically, the guide mechanism includes a guide plate 9, a push plate 10 and an adjusting rod 11. A mounting rod inserted into a strip hole is provided at the bottom of one end of the guide plate 9. The guide plate 9 is fixed by screwing the end of the mounting rod into the fastener and contacting the conveying frame 1. The other end of the guide plate 9 is rotatably connected to the push plate 10. The adjusting rod 11 passes through the side baffle 3 and maintains a threaded connection. A connecting block 13 is rotatably connected to the end of the adjusting rod 11. The connecting block 13 is slidably connected to the push plate 10 and keeps the sliding direction consistent with the conveying direction.

[0040] As described in the previous paragraph, the specific structure of the guide mechanism and its connection form can facilitate the adjustment and fixation of the position of the guide plate and the push plate above the conveyor belt through fasteners and adjustment rods, thereby facilitating the matching of cardboards of different sizes for nailing boxes.

[0041] Please see the attached Figure 3 Specifically, a pad 12 is provided in the gap between the conveyor belt 2 at the lower end of the nail box mechanism. The pad 12 is flush with the top of the conveyor belt 2 and maintains a rounded corner on the top of the side close to the conveying head end.

[0042] As mentioned in the previous paragraph, the spacer is provided to facilitate the nailing operation.

[0043] Before using the box nailing device, the fasteners under the guide plate 9 are loosened in advance according to the size of the cardboard and the position of the nail box so that the guide plate 9 can move and rotate in the strip hole of the conveying frame 1. Then, the adjusting rod 11 is rotated, and the connecting block 13 is pushed or pulled to move linearly in the direction perpendicular to the conveying direction under the action of the screw thread. Since the connecting block 13 is slidably connected to the push plate 10, it will simultaneously push the push plate 10 to move linearly in the direction perpendicular to the conveying direction. After the adjustment is completed, the guide plate 9 can be fixed with fasteners.

[0044] During use, the cardboard is placed on the conveyor belt 2 from the guide mechanism. Under the action of the guide plate 9, the cardboard is automatically positioned and conveyed along the conveyor belt 2. When it reaches the position of the compression belt 5, it is compressed and conveyed to prevent the cardboard from deviating. When it is conveyed to the position of the nailing mechanism, the visual sensor senses the cardboard and sends a control signal to control the linear telescopic device 7 to extend, driving the nailing machine head 8 to descend. After the nailing machine head 8 is lowered, the nails are nailed into the cardboard and contacted with the pad 12 to fix the cardboard together, thereby completing the nailing operation. Then the linear telescopic device 7 retracts to drive the nailing machine head 8 to rise, load the nails and wait for the subsequent nailing of the box, and the nailing process is completed.

[0045] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
