Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, specifically a cardboard feeding mechanism for cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, usually made of corrugated cardboard or single-layer cardboard, used to protect goods. They are widely used in various industries. During the production of cardboard boxes, the raw cardboard often needs to be processed. Feeding mechanisms are often used to feed the raw cardboard. However, existing feeding mechanisms are difficult to adjust significantly because the loading frame is difficult to adjust, making it difficult to feed cardboard of different specifications and affecting the normal feeding of the mechanism. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a cardboard feeding mechanism for carton production, which solves the problem that the feeding mechanism is difficult to feed cardboard of different specifications due to the difficulty in making significant adjustments to the loading frame, thus affecting the normal feeding of the mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cardboard feeding mechanism for carton production, comprising a support frame, a movable groove on one side of the support frame, two bidirectional threaded rods rotatably connected inside the support frame, one of the bidirectional threaded rods being rotatably connected to the inner wall of the movable groove, one end of each of the two bidirectional threaded rods passing through the support frame and fitted with a linkage belt structure, a torque fixedly connected to one side of the linkage belt structure, two movable blocks externally threaded to the bidirectional threaded rods, the movable blocks being slidably connected to the inner wall of the movable groove, a movable plate installed on one side of each movable block, a movable frame slidably connected to one end of the top of the movable plate, several through grooves on one side of the movable frame, a baffle slidably connected inside the movable frame, and a pin installed on the side of the movable frame near the through groove, the pin passing through the through groove and corresponding to the position of the baffle.

[0005] As a further embodiment of this utility model: a fixed frame is fixedly connected to the top end of the movable plate away from the movable frame, and the movable plate is provided with a sliding groove.

[0006] As a further embodiment of this utility model: a return spring is installed on the inner wall of the slide groove, and one end of the return spring is fixedly connected to the movable frame.

[0007] As a further embodiment of this utility model: the bottom of the support frame is fixedly connected to a base, and several rotating wheels are rotatably connected to one side of each movable plate.

[0008] As a further embodiment of this utility model: a motor is fixedly connected to the bottom of the support frame, an output wheel is mounted on the motor through an output shaft, and a transmission belt is movably connected to the output wheel.

[0009] As a further embodiment of this utility model: a transmission wheel is installed on the side of the transmission belt away from the output wheel, the transmission wheel is rotatably connected to the support frame, and several rubber blocks are installed on the outside of the transmission belt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This cardboard feeding mechanism for carton production comprises a rotary knob, a bidirectional threaded rod, a movable plate, and a movable frame. Rotating the rotary knob causes the bidirectional threaded rod to rotate within the movable slot, which in turn causes the movable block outside the threaded rod to move the movable plate. This allows the movable plate to adjust its spacing according to the required width of the cardboard, enabling it to smoothly adapt to cardboard of different widths. Subsequently, pulling the movable frame moves it away from the fixed frame and simultaneously stretches the return spring, thereby adjusting the spacing between the fixed frame and the movable frame. This facilitates the placement of the cardboard between the fixed frame and the movable frame. The return spring, through its elasticity, pulls the movable frame, allowing it to adhere to one side of the cardboard, thus limiting the cardboard's movement and preventing it from tipping over during feeding, thereby improving the stability of the feeding mechanism.

[0012] 2. This cardboard feeding mechanism for carton production, through the setting of a pin, a baffle, an output wheel and a motor, allows the pin to be pulled out to remove the baffle limit before feeding, and the baffle to be pulled so that the height of the baffle can be adjusted according to the thickness of the cardboard. The pin limits the baffle, and then the motor drives the output wheel to rotate, so that the output wheel can drive the transmission belt and make the rubber block outside the transmission belt rub against the bottom of the cardboard to transmit it, thereby stably feeding cardboard of different thicknesses and improving the practicality of the mechanism.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a cardboard feeding mechanism for carton production, including a support frame 1, a base 15 fixedly connected to the bottom of the support frame 1, and several rotating wheels 16 rotatably connected to one side of each movable plate 6. By setting the rotating wheels 16, when the motor 17 drives the transmission belt 19 to feed the cardboard through the output wheel 18, the rotating wheels 16 can rest on both sides under the cardboard, making the movement of the cardboard more stable.

[0019] A motor 17 is fixedly connected to the bottom of the support frame 1. An output wheel 18 is mounted on the motor 17 via an output shaft. A transmission belt 19 is movably connected to the output wheel 18. A transmission wheel 20 is mounted on the side of the transmission belt 19 away from the output wheel 18. The transmission wheel 20 is rotatably connected to the support frame 1. Several rubber blocks 21 are mounted on the outside of the transmission belt 19. By setting the rubber blocks 21, when the motor 17 drives the transmission belt 19 to move via the output wheel 18, the rubber blocks 21 on the outside of the transmission belt 19 can contact the bottom of the cardboard, thereby driving the cardboard to move and facilitating feeding of the cardboard.

[0020] A movable groove 2 is provided on one side of the support frame 1. Two bidirectional threaded rods 3 are rotatably connected inside the support frame 1. One of the bidirectional threaded rods 3 is rotatably connected to the inner wall of the movable groove 2. One end of the two bidirectional threaded rods 3 passes through the support frame 1 and is installed with a linkage belt structure 14. A rotating knob 4 is fixedly connected to one side of the linkage belt structure 14. By setting the rotating knob 4 and rotating the rotating knob 4, the rotating knob 4 can control the movement of the two movable blocks 5 through the bidirectional threaded rods 3, thereby facilitating the adjustment of the distance between the movable plates 6 on one side of the two movable blocks 5.

[0021] The bidirectional threaded rod 3 has two movable blocks 5 connected by external threads. The movable blocks 5 are slidably connected to the inner wall of the movable groove 2. A movable plate 6 is installed on one side of each movable block 5. A fixed frame 7 is fixedly connected to the top of the movable plate 6 away from the movable frame 8. The movable plate 6 has a sliding groove 12. A return spring 13 is installed on the inner wall of the sliding groove 12. One end of the return spring 13 is fixedly connected to the movable frame 8. By setting the return spring 13, the return spring 13 can be stretched as the movable frame 8 moves, so that the return spring 13 generates a relative elastic force through stretching. This makes it convenient for the return spring 13 to drive the movable frame 8 to reset through the elastic force after the feeding is completed, and it is convenient to adjust the position of the movable frame 8 next time.

[0022] A movable frame 8 is slidably connected to one end of the top of the movable plate 6. Several through slots 9 are opened on one side of the movable frame 8. A baffle 11 is slidably connected inside the movable frame 8. A pin 10 is installed on the side of the movable frame 8 near the through slots 9. The pin 10 passes through the through slots 9 and corresponds to the position of the baffle 11. By setting the through slots 9, the pin 10 is inserted into different through slots 9, and the pin 10 fixes the baffle 11 in different positions of the through slots 9, which makes it convenient to limit the adjustment of the baffle 11.

[0023] The working principle of this utility model is as follows:

[0024] In use, rotating the knob 4 causes the double-threaded rod 3 to rotate, which in turn moves the two movable blocks 5 together. The two movable blocks 5 then move the movable plate 6 to adjust the spacing according to the required width of the cardboard, pulling the movable frame 8 so that it slides away from the fixed frame 7 within the groove 12. Simultaneously, as the movable frame 8 slides, the return spring 13 is stretched, generating a relative elastic force. Then, the cardboard to be fed is placed between the fixed frame 7 and the movable frame 8, so that the cardboard rests against one side of the fixed frame 7 and simultaneously rests on the top of the rotating wheel 16 and the transmission belt 19. Release the movable frame 8, allowing the return spring 13 to reset the movable frame 8 through its elastic force, so that the movable frame 8 rests against the side of the cardboard away from the fixed frame 7, thus completing the limitation of the cardboard. Pull out the pin 10, so that the pin 10 disengages from the baffle 11 and cancels the limitation of the baffle 11. Pull the baffle 11, so that the baffle 11 can adjust the extension length according to the thickness of the cardboard. Insert the pin 10 to limit and fix the baffle 11. Start the motor 17, so that the motor 17 drives the transmission belt 19 to slide on the surface of the transmission wheel 20 and the output wheel 18 through the output wheel 18, so that the rubber block 21 on the surface of the transmission belt 19 can drive the cardboard to feed.
