Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figs. 1 to 3 This utility model provides a technical solution: a positioning and pressing mechanism for a nailing machine, including a base plate 1, two supports 2 fixedly connected to the top of the base plate 1, two rollers 3 rotatably inserted between the two supports 2, the two rollers 3 being horizontally arranged, two supports 4 above the supports 2, two rollers 5 rotatably inserted between the two supports 4, a positioning frame 6 fixedly connected between the two supports 4, two vertically arranged guide rods 7 fixedly connected to the top of the base plate 1, the upper end of the guide rods 7 movably passing through the positioning frame 6, a driving component fixedly installed on the top of the guide rods 7, the driving component being used to drive the positioning frame 6 to move vertically.

[0023] The drive assembly includes a main bracket 8 fixed to the top of two guide rods 7. A bidirectional lead screw 9 is rotatably inserted between the two main brackets 8. Two symmetrically distributed nut blocks 11 are threaded on the bidirectional lead screw 9. A horizontally placed limiting rod 10 is fixedly connected between the inner walls of the main brackets 8. The limiting rod 10 is movably inserted through the nut block 11. A connecting rod 12 is rotatably connected to the bottom of the nut block 11. The lower end of the connecting rod 12 is rotatably connected to the positioning frame 6. A handwheel 13 is fixedly connected to the end of the bidirectional lead screw 9.

[0024] By turning the handwheel 13, the double-acting lead screw 9 is driven to rotate. The double-acting lead screw 9 drives the two nut blocks 11 to move closer to each other. The two nut blocks 11 drive the positioning frame 6 to descend through the connecting rod 12. The positioning frame 6 drives the two rollers 5 to move downward through the bracket 2 4, so that the distance between roller 2 5 and roller 1 3 becomes smaller. This adjusts the degree of pressure on the cardboard, making the pressure effect more ideal and ensuring that the subsequent nailing work is completed smoothly.

[0025] Roller 3 and roller 5 have the same specifications. Roller 5 is located directly above roller 3. Firstly, having the same specifications facilitates unified production and maintenance. Secondly, the positional relationship between roller 5 and roller 3 helps to better limit the cardboard.

[0026] A feeding plate 14 is fixedly connected to the base plate 1, and the feeding plate 14 is located in the gap between roller 3 and roller 5.

[0027] The top of the feeding plate 14 is fixedly connected to two symmetrically distributed auxiliary pressing components 15, which are used to press the carton board.

[0028] The auxiliary pressing assembly 15 includes a support 151 fixed to the top of the feeding plate 14. At least two vertically arranged positioning rods 153 are fixedly connected to the end of the support 151. A guide block 154 is slidably sleeved on the positioning rod 153. An arc-shaped pressure plate 155 is fixedly connected to one end of the guide block 154. A spring 152 is fixedly connected between the support 151 and the guide block 154. When the cardboard is pushed in the horizontal direction, the end of the cardboard will squeeze the arc-shaped pressure plate 155, causing the arc-shaped pressure plate 155 to move upward, so that the spring 152 is in a compressed state. The positioning rods 153 guide the guide block 154 in a straight line, so that the guide block 154 and the arc-shaped pressure plate 155 can only move in the vertical direction.

[0029] The bent cardboard is first placed on top of the feed plate 14. Since the feed plate 14 has a U-shaped structure, it can limit the cardboard in the horizontal direction. Then it is pushed towards the roller 2 5 and roller 1 3. At this time, the end of the cardboard is inserted under the arc-shaped pressure plate 155. Under the elastic force of the spring 152, the arc-shaped pressure plate 155 presses and limits the cardboard in the vertical direction, which achieves the purpose of initial limiting.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
