Description

Technical Field

[0001] This invention relates to the field of paper box forming technology, and more specifically to a paper box forming machine. Background Technology

[0002] Cardboard packaging plays a vital role in the sales of goods, especially in attracting consumers, increasing product added value, satisfying consumers' spiritual needs, and consolidating brand and corporate image. This is increasingly recognized. In addition, cardboard boxes protect the products they contain and facilitate product placement and storage.

[0003] As the demand for cardboard boxes increases, and manual production requires a large workforce and is inefficient, making it difficult to balance the consumption of cardboard boxes, cardboard box forming machines have emerged. Using cardboard box forming machines to produce cardboard boxes not only frees up labor but also improves production efficiency to meet the demand for cardboard boxes.

[0004] Most existing paper box forming machines are assembly line processes, requiring manual addition of paper shells, which are then transported one by one to the forming mechanism via suction. After the paper box is formed, it is transported away while waiting for the next paper shell to be added. Therefore, the waiting time during production is long and the actual forming time is short, resulting in a significant waste of time. Thus, there is considerable room for improvement in the production efficiency of paper box forming machines. Summary of the Invention

[0005] This invention addresses the problem that existing paper box forming machines are mostly assembly line processes, requiring manual addition of paper sheets, which are then transported one by one to the forming mechanism via adsorption. After the paper box is formed, it is transported away while waiting for the next paper sheet to be added. As a result, the waiting time during production is long and the actual forming time is short, leading to a significant waste of time. Therefore, there is considerable room for improvement in the production efficiency of paper box forming machines. This invention provides a paper box forming machine.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A paper box forming machine includes a forming section, the forming section comprising a frame for fixing a first linear drive device, the frame being mounted on a fixed base, the output end of the first linear drive device being provided with an extrusion head, and a forming mold for cooperating with the extrusion head to form a paper box being provided below the extrusion head, and a feeding section for feeding the paper shell by rotation being mounted on the frame.

[0008] Furthermore, the bottom of the molding die is provided with a demolding structure.

[0009] Furthermore, the feeding unit includes an L-frame fixed to the frame body. An arc-shaped rod is mounted on one end of the L-frame away from the frame body via a shaft. A paper feeding roller that feeds the paperboard by rotation is mounted on one end of the arc-shaped rod via a mounting bracket. The other end of the arc-shaped rod is mounted on the L-frame via a first spring. This end of the arc-shaped rod is located above the extrusion head.

[0010] Furthermore, the frame is equipped with a support part for holding cardboard boxes. The support part includes a support plate, which is mounted on a fixed base frame. A tray for placing cardboard boxes is mounted on the upper end surface of the support plate via a second spring. Limiting plates are provided on both sides of the support plate.

[0011] Furthermore, the lower end of the support plate is provided with at least one stop bar, the upper end of the stop bar is provided with a chamfer, and the lower end of the stop bar is mounted on the support plate by a third spring.

[0012] Furthermore, an adjustment part is installed on the side wall of the pallet, the adjustment part includes no less than two gantry frames, the two ends of the gantry frames are installed on the side wall of the pallet, and the gantry frames are connected by a connecting plate.

[0013] Furthermore, a U-shaped frame is fitted in the middle of the connecting plate, and limit posts are provided on both sides of the U-shaped frame, with the limit posts fixedly installed on the connecting plate.

[0014] Furthermore, a connecting rope is provided at the bottom of the U-shaped frame, and the connecting rope is connected to a pulley. The pulley is mounted on a fixed base frame via a mounting bracket.

[0015] Furthermore, a paper feeding part is installed on the upper end face of the fixed base frame. The paper feeding part includes an upper paperboard installed by a second linear drive device, and side plates for fixing the position of the paperboard are provided on both sides of the upper paperboard.

[0016] Furthermore, the end of the connecting rope away from the U-shaped frame is mounted on the upper cardboard.

[0017] The beneficial effects of this invention are:

[0018] This device can control the feeding of paper sheets by driving the paper feeding roller through the extrusion head, and can complete the feeding of a single paper sheet through the paper feeding roller during one reciprocating motion of the extrusion head;

[0019] This device changes the original assembly line processing of the paper box forming device, so that the extrusion head can work continuously, avoiding waiting during the paper box feeding and transportation process;

[0020] This device controls the feeding of single sheets of paper by using the chamfered cooperation of the paper feeding roller and the stop bar, which changes the original suction-type paper feeding.

[0021] This device eliminates the traditional manual paper feeding method and achieves a higher degree of automation.

[0022] This device can automatically lower the tray during the paper feeding process, making it convenient to add paper sheets. Attached Figure Description

Detailed Implementation Example 1

[0034] like Figures 1-5As shown, this embodiment discloses a cardboard box forming machine, including a forming section 1. The forming section 1 includes a frame 11 for fixing a first linear drive device 12. The frame 11 is mounted on a fixed base frame 5. The frame 11 has a portal frame structure, and the linear drive device 12 is mounted on its horizontal end. The first linear drive device 12 can be hydraulically driven, screw driven, or electric push rod, etc. The output end of the first linear drive device 12 is provided with an extrusion head 13. The extrusion head 13 is made of a material with a hardness greater than that of the cardboard shell, preferably stainless steel, cast iron, etc. Below the extrusion head 13 is a forming mold 14 for cooperating with the extrusion head 13 to form the cardboard box. The forming mold 14 has a box structure, and its internal dimensions are slightly smaller than the dimensions of the extrusion head 13. The lower end face of the forming mold 14 is fixedly mounted on the mounting base plate via the base frame 15. The mounting base plate is provided with a baffle 16 for limiting the position of the cardboard. The baffle 16 ensures that the center position of the cardboard is on the same straight line as the center of the forming mold 14. A feeding part 17 is mounted on the frame 1 to feed the cardboard by rotation. A demolding structure is provided at the bottom of the forming mold 14 to facilitate the removal of the cardboard box after forming. Preferably, the demolding structure has an electric door at the bottom of the forming mold 14. The electric door is made of a material with a hardness greater than that of the cardboard, such as stainless steel or cast iron. The electric door is driven by a sensor and controller. When the cardboard box is formed, the sensor detects changes in pressure... The signal is transmitted to the controller, which drives the electric door to open and then close. The electric door can open in the following ways: a double door on opposite sides, a double door on one side, or a pull-out door. It opens completely to ensure the paper box falls out. The feeding unit 17 includes an L-frame 171 fixed to the frame 11. The L-frame 171 is fixedly installed at the horizontal end of the frame 11, and its installation method can be welding or bolt connection, etc. An arc-shaped rod 172 is mounted on the end of the L-frame 171 away from the frame 11 via a shaft. The connection point is located in the middle of the arc-shaped rod 172, which can rotate freely around the connection point. One end of the arc-shaped rod 172 is mounted on a paper feeding roller 174 that feeds the paper box by rotation via a mounting bracket 173. The rotation of the arc-shaped rod 172 allows... The height of the paper feed roller is controlled to determine whether it contacts the paper shell. The paper feed roller 174 can rotate freely on the mounting frame 173. A matching motor is installed on the paper feed roller 174. To increase the friction between the paper feed roller 174 and the paper shell, the outside of the paper feed roller 174 is covered with a friction layer, preferably made of rubber or silicone. During the rotation of the paper feed roller 174, it contacts the paper shell, and the torque generated by the rotation of the paper feed roller 174 drives the paper shell to move, thus feeding the paper shell. The other end of the arc-shaped rod 172 is mounted on the L-frame 171 through a first spring 175. The first spring 175 is a thrust spring, which ensures that the paper feed roller 174 is separated from the paper shell under normal conditions.One end of the arc-shaped rod 172, connected to the first spring 175, is located above the extrusion head 13. During the upward movement of the extrusion head 13, the upper surface of the extrusion head 13 contacts the arc-shaped rod 172, compressing the first spring 175. This causes the first spring to store energy and simultaneously drive the arc-shaped rod 172 to swing, bringing the paper feed roller 174 into contact with the paper shell, thus feeding the paper shell. During the downward movement of the extrusion head 13, the extrusion head 13 separates from the arc-shaped rod 172, and the first spring 175 releases energy, causing the paper feed roller 174 to separate from the paper shell, stopping the paper shell feeding and thus preventing the paper shell feeding from affecting the operation of the extrusion head 13.

[0035] Example 2

[0036] Based on Example 1, such as Figure 6 , Figure 7As shown, in this embodiment, a support part 2 for holding cardboard boxes is installed on the frame 11. The support part 2 includes a support plate 21, which is mounted on a fixed base frame 5. The support plate 21 is inclined, which facilitates the removal of cardboard boxes. A tray 23 for placing cardboard boxes 24 is installed on the upper end surface of the support plate 21 via a second spring 22. The second spring 22 is a thrust spring, which applies a thrust to the tray 23, thereby pushing the cardboard boxes 24. To prevent the cardboard boxes 24 from falling off the support part 2 due to the thrust of the tray 23, the... Limiting plates 25 are provided on both sides of the support plate 21. The limiting plates 25 are L-shaped, and their vertical ends are fixedly installed on the support plate 21. The connection method can be bolt connection or welding. The horizontal end contacts the upper end surface of the uppermost cardboard shell 24 to prevent the cardboard shell from falling off. To prevent the cardboard shell 24 from sliding off the bottom of the support plate 23, at least one stop bar 26 is provided at the bottom of the support plate 21. The upper end of the stop bar 26 is chamfered, and the size of the chamfer depends on the thickness of the cardboard shell 24, so that the cardboard shell 24 can push the stop bar 26 downward through the chamfer. The lower end of the stop bar 26 is connected by a third spring 2. 7. Mounted on the support plate 21, the support plate 21 has a groove for mounting the stop rod 26 to ensure linear movement. The groove is a blind groove, and its size is the same as that of the stop rod 26, allowing the stop rod 26 to slide freely within it. The two ends of the third spring 27 are respectively mounted on the lower end of the stop rod 26 and the bottom surface of the groove. The third spring 27 is a thrust spring, which pushes the stop rod 26 to block the paper shell 24. When the paper shell 24 is subjected to friction from the paper feed roller 174, it pushes the stop rod 26 to compress the third spring 27, ensuring the passage of the paper shell 24. After the cardboard 24 is fed, the third spring 27 releases energy, causing the stop bar 26 to return to the state of blocking the cardboard 24. An adjustment part 3 is installed on the side wall of the pallet 23. The adjustment part 3 includes no less than two gantry frames 31. The two ends of the gantry frames 31 are installed on the side wall of the pallet 23. The middle position of the horizontal end of the gantry frames 31 is connected by a connecting plate 32. The gantry frames 31 can be used to pull the pallet 23 from below the support plate 21 to facilitate the addition of cardboard. Multiple gantry frames 31 can be driven at the same time through the connecting plate 32. Setting no less than two gantry frames 31 can make the pallet 23 bear force evenly.

[0037] Example 3

[0038] Based on Example 2, such as Figure 8 , Figure 9As shown, in this embodiment, a U-shaped frame 34 is fitted in the middle of the connecting plate 32. The U-shaped frame 34 can be replaced by an O-shaped frame, and its internal space is greater than the thickness of the connecting plate 32. The U-shaped frame 34 can pull the connecting plate 32 to move, thereby controlling the movement of the support plate 23. Limiting posts 33 are provided on both sides of the U-shaped frame 34. The limiting posts 33 are fixedly installed on the connecting plate 32. The limiting posts 33 are cylindrical and are tangent to the U-shaped frame 34 or have a small gap with the U-shaped frame 34. When the U-shaped frame 34 is under force, the limiting posts 33 contact the U-shaped frame 34 through their curved surfaces. The contact is line contact, so the U-shaped frame can swing on the connecting plate 32. At this time, the force applied to the U-shaped frame 34 can be at a certain angle to the vertical direction of the connecting plate 32, making the direction of the applied force more extensive. A connecting rope 35 is provided at the bottom of the U-shaped frame 34, and the connecting rope 35 is connected to a pulley 36. The pulley 36 is equivalent to a fixed pulley, which can change the direction of the applied force. The pulley 36 is mounted on the fixed base 5 via a mounting bracket. Through the connecting rope 35 and the pulley 36, the support plate 23 can be adjusted and controlled from outside the device, making the adjustment position of the support plate 23 more extensive. A paper feeding section 4 is installed on the upper end face of the base frame 5. The paper feeding section 4 includes an upper cardboard 41 mounted on it via a second linear drive device 43. The second linear drive device 43 can be hydraulically driven, screw driven, or electric push rod, etc. Side plates 42 for fixing the position of the cardboard are provided on both sides of the upper cardboard 41. The cardboard is placed on the upper cardboard 41. The placement method can be a forklift or crane. The second linear drive device can drive the upper cardboard 41 to move upward. When the height of the upper cardboard 41 is not less than the height of the pallet, it is convenient to load the cardboard. The connecting rope 35 is away from the U-shaped frame 34. The tray 23 is mounted on the upper cardboard 41. With this configuration, when the cardboard is used up, the tray 23 is at its highest point. During the upward movement of the upper cardboard 41, the pulley 36 can pull the tray 23 downward via the connecting rope 35. When the upper cardboard 41 rises to its highest point, the tray 23 is at its lowest point, which facilitates the loading of the cardboard. After the cardboard is loaded, the upper cardboard 41 is controlled to descend by the second linear drive device 43. At this time, the tray 23 is still at its lowest point due to the pressure of the cardboard. In this state, the connecting rope 35 is in a slack state. As the tray 23 gradually rises, the connecting rope 35 is gradually tightened.

[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
