Description

Technical Field

[0001] This application relates to the field of paper box production technology, specifically to a bottom unit for an irregularly shaped paper box. Background Technology

[0002] Paper box production is a manufacturing sector involving multiple processes. Its core lies in the fine processing of various raw materials into various types of paper packaging boxes. As a professional manufacturer in this field, paper box factories focus on producing a variety of paper packaging products such as cartons, paper boxes, paper bags, playing cards, paper pallets, and paper cards. These products have been widely used and recognized in many industries such as food, medicine, daily necessities, and electronics due to their good protective performance and environmental protection characteristics.

[0003] In the process of paper box production and processing, cardboard needs to be bent to facilitate subsequent paper box assembly. Existing cardboard bending devices can generally only bend individual cardboard pieces, resulting in low efficiency and room for improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a peripheral bottom unit for irregularly shaped paper boxes, which has the advantages of being able to complete the bending operation of paperboard during the paperboard conveying process, improving the bending efficiency of paperboard, and thus improving the overall production and processing speed of paper boxes. It solves the problem that existing paperboard bending devices can generally only bend individual paperboards, resulting in low operating efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a bottom unit for an irregularly shaped paper box, comprising a base, two conveyor rollers rotatably connected inside the base, a first conveyor belt drivingly connected between the two conveyor rollers, equidistantly arranged brackets fixedly connected to the upper surface of the base, a first cylinder fixedly connected to the top of each bracket, a frame fixedly connected to the output end of the first cylinder, equidistantly arranged drive wheels rotatably connected inside the frame, a second conveyor belt drivingly connected to the outer circumferential surfaces of the drive wheels, a bending plate provided on the upper surface of the base, the bending plate comprising a horizontal section, a transition bending section and a vertical section, the bottom surface of the horizontal section fixedly connected to the upper surface of the base, a fixing plate fixedly connected to the outer surface of the base, a lead screw rotatably connected inside the fixing plate, a threaded tube threadedly connected to the outer circumferential surface of the lead screw, the side of the threaded tube away from the lead screw fixedly connected to the outer surface of the vertical section, two second cylinders provided on the upper surface of the frame located on one side of the bending plate, a limiting plate fixedly connected to the output end of the two second cylinders, and equidistantly arranged cardboard on the upper surface of the first conveyor belt.

[0006] The above solution addresses the issue that existing cardboard bending devices can only bend individual cardboard pieces, resulting in low efficiency. By installing a bending plate and a limiting plate consisting of a horizontal section, a transition bending section, and a vertical section, the bending process can be completed during cardboard conveying, improving cardboard bending efficiency and thus increasing the overall production speed of cardboard boxes.

[0007] Furthermore, the bottom surface of the limiting plate is slightly higher than the bottom surface of the second conveyor belt, and the corners of the limiting plate are all arc-shaped structures.

[0008] The above solution avoids the limiting plate from squeezing the cardboard and affecting the cardboard conveying operation. The arc-shaped structure at the corners of the limiting plate can prevent scratching the cardboard.

[0009] Furthermore, each of the frames has two guide rods fixedly connected to its upper surface, and the outer circumferential surface of the guide rods is slidably inserted into the interior of the bracket.

[0010] The above scheme restricts the frame, causing it to move longitudinally up and down continuously, thus improving the stability of the frame's movement and consequently the stability of the second conveyor belt's movement.

[0011] Furthermore, a sprocket is fixedly fitted onto the outer circumferential surface of each drive wheel, and multiple sprockets are connected by chain drive. A motor is fixedly connected to the outer surface of each frame, and the output end of the motor is connected to one of the drive wheels.

[0012] The above scheme allows a motor to drive a drive wheel to rotate, and the linkage between the drive wheels is achieved through sprockets and chains, enabling the drive wheels to move synchronously, thereby driving the second conveyor belt to operate.

[0013] Furthermore, the bending plate is made of a metal material with a certain elastic deformation capability, and the outer surface of the bending plate is coated with an anti-rust coating.

[0014] Through the above solution, the metal material with a certain degree of elastic deformation enables the bending plate to meet the movement requirements of the vertical section, thereby adjusting the bending position of the cardboard as needed. The anti-rust coating on the outer surface of the bending plate can protect the bending plate, prevent it from easily rusting, and extend its service life.

[0015] Furthermore, two limiting rings are fixedly sleeved on the outer circumferential surface of the lead screw, and the side of the limiting rings closest to the fixed plate contacts the outer surface of the lead screw.

[0016] The above method restricts the lead screw, preventing it from slipping and deviating, and improving the stability of the lead screw's movement.

[0017] Furthermore, two limiting rods are fixedly connected to the outer surface of the vertical segment, and the outer circumferential surface of the limiting rods is slidably inserted into the interior of the fixing plate.

[0018] The above scheme restricts the threaded tube, preventing it from rotating with the lead screw and ensuring that the threaded tube always drives the vertical section to move laterally. It also supports the vertical section and improves its stability.

[0019] Furthermore, a support plate is fixedly connected to the inner wall of the base, and the upper surface of the support plate is in contact with the inner top wall of the first conveyor belt.

[0020] The above solution supports the first conveyor belt, preventing it from denting and affecting the normal transport of the cardboard.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This irregularly shaped cardboard box peripheral unit, by setting a bending plate and a limiting plate consisting of a horizontal section, a transition bending section and a vertical section, can complete the bending operation of the cardboard during the cardboard conveying process, improve the efficiency of cardboard bending operation, and thus improve the overall production and processing speed of the cardboard box. By rotating the lead screw to drive the vertical section to move under the action of the threaded tube, and by driving the limiting plate to move through the second cylinder, the bending position of the cardboard can be adjusted as needed, improving the flexibility and practicality of the device.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, a peripheral unit for an irregularly shaped cardboard box includes a base 1. Two conveyor rollers 3 are rotatably connected inside the base 1, and a first conveyor belt 4 is driven between the two conveyor rollers 3. Equally spaced brackets 5 are fixedly connected to the upper surface of the base 1. A first cylinder 6 is fixedly connected to the top of each bracket 5. A frame 7 is fixedly connected to the output end of the first cylinder 6. Equally spaced drive wheels 8 are rotatably connected inside the frame 7. A second conveyor belt 9 is drivenly connected to the outer circumference of the multiple drive wheels 8. A bending plate 10 is provided on the upper surface of the base 1. The bending plate 10 includes a horizontal section 1001 and a... The bottom surface of the bending section 1002 and the vertical section 1003 and the horizontal section 1001 are fixedly connected to the upper surface of the base 1. The outer surface of the base 1 is fixedly connected to the fixing plate 11. The fixing plate 11 is rotatably connected to the lead screw 12. The outer circumferential surface of the lead screw 12 is threadedly connected to the threaded tube 13. The side of the threaded tube 13 away from the lead screw 12 is fixedly connected to the outer surface of the vertical section 1003. Two second cylinders 14 are provided on the upper surface of the frame 7 located on one side of the bending plate 10. A limiting plate 15 is fixedly connected to the output end of the two second cylinders 14. The upper surface of the first conveyor belt 4 is provided with cardboard 21 arranged at equal intervals.

[0032] Please see Figure 1 and Figure 2 The bottom surface of the limiting plate 15 is slightly higher than the bottom surface of the second conveyor belt 9. The corners of the limiting plate 15 are all arc-shaped to avoid the limiting plate 15 squeezing the cardboard 21 and affecting the conveying operation of the cardboard 21. The arc-shaped structure at the corners of the limiting plate 15 can prevent scratching the cardboard 21.

[0033] Please see Figure 1, Figure 2 and Figure 5 Two guide rods 16 are fixedly connected to the upper surface of each frame 7. The outer circumferential surface of the guide rods 16 is slidably inserted into the inside of the bracket 5 to restrict the frame 7, so that the frame 7 always moves longitudinally, thereby improving the stability of the frame 7's movement and thus improving the stability of the second conveyor belt 9's movement.

[0034] Please see Figure 1 and Figure 5 Each drive wheel 8 has a sprocket 17 fixedly fitted on its outer circumference. Multiple sprockets 17 are connected by chain drive. Each frame 7 has a motor 18 fixedly connected to its outer surface. The output end of the motor 18 is connected to one of the drive wheels 8. The motor 18 can drive one drive wheel 8 to rotate. The sprocket 17 and the chain realize the linkage between the drive wheels 8, so that the drive wheels 8 can move synchronously, thereby driving the second conveyor belt 9 to operate.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The bending plate 10 is made of metal with a certain elastic deformation capability. The outer surface of the bending plate 10 is coated with an anti-rust coating. The metal with a certain elastic deformation capability enables the bending plate 10 to meet the movement requirements of the vertical section 1003, thereby adjusting the bending position of the cardboard 21 as needed. The anti-rust coating on the outer surface of the bending plate 10 can protect the bending plate 10, prevent the bending plate 10 from easily rusting, and extend the service life of the bending plate 10.

[0036] Please see Figure 1 , Figure 2 and Figure 4 Two limiting rings 19 are fixedly sleeved on the outer circumferential surface of the lead screw 12. The side of the limiting rings 19 closest to the fixed plate 11 contacts the outer surface of the lead screw 12 to restrict the lead screw 12, prevent the lead screw 12 from sliding and deviating, and improve the stability of the movement of the lead screw 12.

[0037] Please see Figure 1 , Figure 2 and Figure 4 Two limiting rods 20 are fixedly connected to the outer surface of the vertical section 1003. The outer circumferential surface of the limiting rods 20 is slidably inserted into the inside of the fixing plate 11 to restrict the threaded tube 13, prevent the threaded tube 13 from rotating with the lead screw 12, and ensure that the threaded tube 13 always drives the vertical section 1003 to move laterally. At the same time, it can also support the vertical section 1003 and improve the stability of the vertical section 1003.

[0038] Please see Figure 1 and Figure 3A support plate 2 is fixedly connected to the inner wall of the base 1. The upper surface of the support plate 2 contacts the inner top wall of the first conveyor belt 4 to support the first conveyor belt 4 and prevent the first conveyor belt 4 from sinking, which would affect the normal conveying of the cardboard 21.

[0039] In this embodiment, an irregularly shaped cardboard box bottom unit, by setting a bending plate 10 composed of a horizontal section 1001, a transition bending section 1002, and a vertical section 1003, and a limiting plate 15, can complete the bending operation of the cardboard 21 during the conveying process, improve the bending efficiency of the cardboard 21, and thus improve the overall production and processing speed of the cardboard box. By rotating the lead screw 12 to drive the vertical section 1003 to move under the action of the threaded tube 13, and by driving the limiting plate 15 to move through the second cylinder 14, the bending position of the cardboard 21 can be adjusted as needed, improving the flexibility and practicality of the device.

[0040] It should be noted that the bending plate 10 is integrally formed, and the transition bending section 1002 is the curved transition area formed by folding between the horizontal section 1001 and the vertical section 1003.

[0041] The working principle of the above embodiments is as follows:

[0042] The first cylinder 6 can be activated to drive the frame 7 to move downwards. The frame 7 drives the second conveyor belt 9 to move downwards via the drive wheel 8, causing the second conveyor belt 9 to press the cardboard 21 down onto the first conveyor belt 4. Then, the motor 18 can be activated to drive one of the drive wheels 8 to rotate. The drive wheel 8 can be linked with the chain via the sprocket 17, thereby driving the second conveyor belt 9 to operate. The second conveyor belt 9 then moves the cardboard 21 forward with the cooperation of the first conveyor belt 4, conveying the cardboard 21. When conveying the cardboard 21, one end of the cardboard 21 needs to rest on the upper surface of the horizontal section 1001. When the cardboard 21 passes through the transition bending section 1002, it will be gradually bent and lifted by the curved structure of the transition bending section 1002. The cardboard 21 is lifted, and the limiting plate 15 can abut against the bending position of the cardboard 21, causing the cardboard 21 to bend with the limiting plate 15 as the reference. When the cardboard 21 reaches the vertical section 1003, the cardboard 21 in the conveying process is in a completely vertical state under the action of the limiting plate 15 and the vertical section 1003. At this time, creases appear on the cardboard 21, and the bending operation is completed. With the continuous conveying of the second conveyor belt 9, the cardboard 21 continues to move forward for subsequent processing operations. The rotatable screw 12 drives the vertical section 1003 to move through the threaded tube 13. At the same time, the second cylinder 14 is activated to drive the limiting plate 15 to move the vertical section 1003 by the same distance, thereby adjusting the bending position of the cardboard 21 as needed.
