Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding machine technology, and in particular to an automatic folding machine. Background Technology
[0002] Cardboard, also known as paperboard, can be made into cartons. The process of making cartons requires bending the cardboard to form a four-sided box structure, so a folding machine is needed.
[0003] While existing folding machines can achieve automatic folding, they lack a mechanism to limit the position of the cardboard. As a result, when the cardboard is subjected to an upward lifting force during the folding process, its position is prone to tilting or even shifting. This reduces the folding effect of existing folding machines and also decreases the stability of the cardboard during the folding process. Therefore, we propose an automatic folding machine. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing an automatic folding machine that solves the problem of low stability during the cardboard folding process.
[0005] To solve the above-mentioned technical problems, this utility model solves the problem of low stability during the cardboard folding process through the following technical solution.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic folding machine includes a base with grooves on both outer walls. A motor is fixedly mounted on the outer wall of the base, and a lead screw is fixedly mounted on the output shaft of the motor. A movable seat is threadedly connected to the outer wall of the lead screw. A support plate is fixedly mounted on the outer wall of the movable seat. A rotating groove is formed on the outer wall of the support plate, and a rotating plate is rotatably connected to the inner wall of the rotating groove. A motor is fixedly mounted on both outer walls of the support plate, and a fixed plate is fixedly mounted on the inner wall of the mounting groove. A fixed frame is fixedly mounted on the top of the fixed plate, and an electric telescopic rod is fixedly mounted on the top of the fixed frame. A pressure plate is fixedly mounted on the output shaft of the electric telescopic rod. A movable frame is fixedly mounted on the outer wall of the movable seat, and an electric telescopic rod is fixedly mounted on the top of the movable frame. A pressure plate is fixedly mounted on the output shaft of the electric telescopic rod. A reinforcing rod is fixedly mounted on the outer wall of the movable frame. The main body is placed on top of the support plate.
[0008] As a preferred technical solution of this utility model: the output shaft of the second motor is fixedly assembled with the outer wall of the support plate, and the top of the rotating plate and the support plate are tightly fitted with the bottom of the body.
[0009] As a preferred technical solution of this utility model: the outer wall of the rotating plate is fixedly equipped with a positioning rod, and the support plate rotates 90° around the positioning rod as the axis.
[0010] As a preferred technical solution of this utility model: the main body is fixedly connected to the rotating plate through the second electric telescopic rod and the first pressure plate, and both the first pressure plate and the second electric telescopic rod are made of rubber.
[0011] As a preferred technical solution of this utility model: the number of electric telescopic rods is two, and the two electric telescopic rods are symmetrically distributed along the top of the fixed frame.
[0012] As a preferred technical solution of this utility model: the inner wall of the slide groove is slidably connected to the outer wall of the movable seat, and the outer wall of the movable seat is slidably connected to the outer wall of the base.
[0013] As a preferred technical solution of this utility model: the outer wall of the second pressure plate is slidably connected to the outer wall of the movable frame, and when the top of the first pressure plate is in contact with the outer wall of the fixed frame, there is a 5cm gap between the first pressure plate and the second electric telescopic rod.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This automatic folding machine, through its base, fixed plate, fixed frame, pressure plate one, and pressure plate two structure, allows the user to extend the output shafts of electric telescopic rod one and electric telescopic rod two to make pressure plate one and pressure plate two contact the top of the main body during operation. This clamps the unfolded part of the main body, ensuring that the main body does not tilt or shift position during the rotation and folding process, thereby improving the stability of the main body and the folding effect of the machine.
[0016] This automatic folding machine, through its structure consisting of a lead screw, motor, slide, slide block, moving frame, support plate, and fixed frame, allows the user to adjust the height of pressure plate one and pressure plate two during operation. This, combined with the movement of the moving frame, adjusts the distance between the main body and the fixed frame, enabling folding operations on bodies of different thicknesses. It also ensures that folding operations can be performed on different positions of the main body, thereby increasing the applicability of the device. Attached Figure Description

A support plate 14 is fixedly mounted on the outer wall of the movable seat 9. A rotating groove 17 is formed on the outer wall of the support plate 14. A rotating plate 12 is rotatably connected to the inner wall of the rotating groove 17. Mounting grooves 16 are formed on both outer walls of the support plate 14. A second motor 11 is fixedly mounted on the inner wall of the mounting groove 16. Both sides of the outer wall of the 1 are fixedly fitted with fixing plates 5. The top of the fixing plate 5 is fixedly fitted with a fixing frame 6. The top of the fixing frame 6 is fixedly fitted with an electric telescopic rod 7. The output shaft of the electric telescopic rod 7 is fixedly fitted with a pressure plate 8. The outer wall of the movable seat 9 is fixedly fitted with a movable frame 10. The top of the movable frame 10 is fixedly fitted with an electric telescopic rod 18. The output shaft of the electric telescopic rod 18 is fixedly fitted with a pressure plate 19. The outer wall of the movable frame 10 is fixedly fitted with a reinforcing rod 13. The body 15 is placed on the top of the support plate 14.
[0029] In the above structure, the base 1, slide 2, motor 1 3, lead screw 4, fixing plate 5, fixing frame 6, electric telescopic rod 1 7, pressure plate 1 8, and moving seat 9 allow the user to adjust the distance between pressure plate 2 19 and rotating plate 12 by retracting the output shafts of electric telescopic rod 1 7 and electric telescopic rod 2 18 during the use of the bending machine. This facilitates the user to place the body 15 of different thicknesses into the bending machine for clamping and bending operations. At the same time, the pressure plate 1 8 and pressure plate 2 19 are used to clamp the body 15, thereby ensuring the stability of the body 15 during the bending process.
[0030] In a preferred embodiment: the output shaft of motor 11 is fixedly assembled with the outer wall of the support plate 14, and the top of both the rotating plate 12 and the support plate 14 are tightly fitted with the bottom of the body 15.
[0031] In the above structure, the rotating plate 12 and the support plate 14 structure enable the device to automatically flip one end of the body 15 that is attached to the support plate 14 by rotating the support plate 14 during use, so that the user does not need to manually fold the edge of the body 15, thereby improving the automation of the device and the user's work efficiency.
[0032] In a preferred embodiment, a positioning rod is fixedly mounted on the outer wall of the rotating plate 12, and the support plate 14 rotates 90° about the positioning rod as the axis.
[0033] In the above structure, the positioning rod structure allows the body 15 to automatically bend at one end near the pallet 14 during the flipping process, thereby enabling the device to automatically complete the folding operation and ensuring the normal operation of the device.
[0034] In a preferred embodiment, the main body 15 is fixedly connected to the rotating plate 12 via an electric telescopic rod 18 and a pressure plate 8, and both the pressure plate 8 and the electric telescopic rod 18 are made of rubber.
[0035] In the above structure, the rubber material has the characteristics of elasticity and toughness, which can effectively reduce the friction of the body 15 when the pressure plate 18 and the pressure plate 2 19 are attached to the body 15, thereby avoiding the situation where the body 15 is severely worn and its quality decreases, and thus ensuring the folding effect of the device on the body 15.
[0036] In a preferred embodiment, there are two electric telescopic rods 7, and both electric telescopic rods 7 are symmetrically distributed along the top of the fixing frame 6.
[0037] In the above structure, the two electric telescopic rods 7 are designed so that both ends of the pressure plate 8 can be driven to fit tightly against the top of the body 15, so that the unbent part of the body 15 will not tilt or even shift in position, thus ensuring that the bent part of the body 15 will not shift in position, thereby improving the stability of the device during the bending process of the body 15.
[0038] In a preferred embodiment: the inner wall of the slide groove 2 is slidably connected to the outer wall of the movable seat 9, and the outer wall of the movable seat 9 is slidably connected to the outer wall of the base 1.
[0039] In the above structure, the base 1 and the movable seat 9 allow the user to adjust the position of the main body 15 by moving the movable seat 9 during operation, thereby achieving the effect of bending the main body 15 at different positions and thus improving the working range of the device.
[0040] In a preferred embodiment: the outer wall of the second pressure plate 19 is slidably connected to the outer wall of the movable frame 10, and when the top of the first pressure plate 8 is in contact with the outer wall of the fixed frame 6, there is a 5cm gap between the first pressure plate 8 and the second electric telescopic rod 18.
[0041] In the above structure, the pressure plate 8 ensures that the moving frame 10 will not come into contact with the electric telescopic rod 7 and the pressure plate 8 during operation. This prevents the electric telescopic rod 18 from being obstructed during movement, thus ensuring that the position of the main body 15 can be flexibly adjusted. This allows the user to adjust the distance between the bending point of the main body 15 and the pressure plate 8, thereby enabling the device to bend the main body 15 at different positions.
[0042] Working principle: After assembling the device, the user can adjust the height of the pressure plate 18 and pressure plate 29 by operating the electric telescopic rod 17 and electric telescopic rod 28, thereby achieving the effect of clamping the body 15 of different thicknesses. This ensures that the device can bend the body 15 of different thicknesses, thus increasing the range of applications of the device. During the bending process, the user can adjust the distance between the body 15 and the pressure plate 18 by moving the movable seat 9, thereby adjusting the position of the body 15 to bend the body 15 at different positions, improving the bending effect of the device and thus improving its practicality.
[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
