Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of cardboard box processing technology, and more specifically, to an adjustable corrugating machine for cardboard box production. Background Technology
[0002] Traditional corrugating machines, as the core equipment in carton production, have gradually revealed many limitations in the face of current market demands. In the cardboard conveying process, the feeding rollers of conventional corrugating machines often use a fixed transmission method. The feeding speed and force are difficult to adjust flexibly according to the material of the cardboard (such as paper of different weights or special materials), thickness, and production process requirements. When handling thin and soft cardboard, the feeding rollers are prone to causing the cardboard to wrinkle or even break due to excessive force. When conveying thick and hard cardboard, insufficient power may cause the feeding to be obstructed or jammed, which seriously affects production efficiency and cardboard processing quality.
[0003] Furthermore, traditional corrugating machines have relatively simple limiting and adjustment functions for the feeding rollers. During operation, the feeding rollers are easily affected by factors such as mechanical vibration and uneven friction of the cardboard, resulting in deviation and jumping. This not only leads to unstable cardboard conveying paths, causing alignment deviations and poor corrugation in subsequent processing and reducing product qualification rates, but also may damage other parts of the equipment due to abnormal movement of the feeding rollers, increasing equipment maintenance costs and downtime. When it is necessary to change cardboard specifications for production, the adjustment process of traditional corrugating machines is cumbersome and complicated, often requiring manual adjustment of multiple parts one by one, which consumes a lot of time and manpower and cannot meet the needs of modern carton manufacturers for rapid order switching and efficient production. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an adjustable corrugating machine for carton production, which solves the technical problems of conventional corrugating machines in the prior art, where the feeding rollers often adopt a fixed transmission method, making it difficult to flexibly adjust the feeding speed and force according to the material, thickness and production process requirements of the cardboard. When processing thin and soft cardboard, the feeding rollers are prone to causing the cardboard to wrinkle or even break due to excessive force; while when conveying thick hard cardboard, insufficient power may cause the feeding to be obstructed or jammed, seriously affecting production efficiency and cardboard processing quality.
[0005] According to one aspect, at least one embodiment of this disclosure provides an adjustable corrugating machine for carton production, comprising:
[0006] The corrugating machine body has a feeding roller on its side wall;

A rotating shaft is disposed on the drive frame. A rotating wheel is disposed at the end of the rotating shaft. An extension block is disposed on the side wall of the rotating wheel. A drive shaft is disposed on the extension block. A positioning sleeve is fitted on the drive shaft. A linkage frame is disposed on the lower end face of the positioning sleeve. The bottom of the linkage frame is fixedly connected to the feeding roller.
[0010] As a further technical solution, a connecting piece is provided at the end of the drive shaft, and the connecting piece is movably fitted with the rotating shaft.
[0011] As a further technical solution, the drive limiting component includes a support plate, which is disposed on the side wall of the corrugating machine body. The support plate is fixedly connected to the drive frame, and a pressure plate is disposed on the inner side wall of the support plate. The feeding roller is in contact with the pressure plate.
[0012] As a further technical solution, the inner sidewall of the support plate is provided with a limiting slide, and both ends of the feeding roller are embedded in the limiting slide.
[0013] As a further technical solution, the side wall of the drive frame is provided with a drive slide rail, the drive slide rail is provided with a sliding hole, the sliding hole is connected to the drive frame, and the end of the rotating shaft is inserted into the sliding hole.
[0014] As a further technical solution, a locking nut is provided inside the drive slide, and the locking nut is fixedly connected to the rotating shaft.
[0015] As a further technical solution, both ends of the rotating shaft are embedded in the drive hole, and one side of the rotating shaft is connected to the locking nut by a bolt. The bolt and the rotating shaft are movably connected by a bearing.
[0016] As a further technical solution, there are two of each of the mounting plate, the drive frame, and the support plate, and several of the mounting plates, the drive frame, and the support plate are located on opposite side walls of the same side of the corrugating machine body.
[0017] The beneficial effects of the embodiments disclosed herein are as follows:
[0018] In this disclosure, the drive feeding assembly of the adjustable corrugating machine, through a unique structural design, enables precise adjustment of the feeding speed and force of the feeding rollers. The coordinated operation of the rotating shaft, rotating wheel, extension block, drive shaft, and positioning sleeve allows the operator to flexibly adjust the position of the positioning sleeve on the drive shaft according to the material, thickness, and production process requirements of the cardboard. This, in turn, changes the motion parameters transmitted from the linkage frame to the feeding rollers. When handling thin and soft paper, the feeding force of the feeding rollers can be reduced to prevent cardboard wrinkles and damage; while for thick and hard cardboard, the feeding power can be increased to ensure smooth feeding. This effectively solves the adaptability problem of traditional corrugating machines in the cardboard conveying process, greatly improving the equipment's adaptability to different cardboard types. The processing capacity of the same specification cardboard meets diverse production needs. The drive limiting component provides stable and reliable limiting and guiding functions for the feeding roller. The pressure plate is in close contact with the feeding roller, using its own elastic material properties to buffer the vibration and impact of the feeding roller during operation and limit its excessive vertical movement. The limiting slide further constrains the movement trajectory of the feeding roller, ensuring its stable operation in the horizontal direction. This dual limiting mechanism effectively avoids the problem of unstable cardboard conveying path caused by the offset and jumping of the feeding roller, so that the cardboard can be accurately aligned in subsequent corrugating, printing and other processing stages, reducing the scrap rate caused by conveying deviation and greatly improving the quality and pass rate of carton products.

[0030] like Figures 1-3 As shown, it illustrates an adjustable corrugating machine for carton production according to this disclosure, comprising:
[0031] The corrugating machine body 1 has a feeding roller 2 installed on its side wall;
[0032] Drive plate feeding assembly 3, which is installed on the side wall of the corrugating machine body 1;
[0033] Drive limit component 4 is installed on the corrugating machine body 1;
[0034] The drive feeding assembly 3 includes a mounting plate 3-1, which is set on the side wall of the corrugating machine body 1. A drive frame 3-2 is set at the lower end of the mounting plate 3-1. A rotating shaft 3-3 is set on the drive frame 3-2. A rotating wheel 3-4 is set at the end of the rotating shaft 3-3. An extension block 3-5 is set on the side wall of the rotating wheel 3-4. A drive shaft 3-6 is set on the extension block 3-5. A positioning sleeve 3-7 is fitted on the drive shaft 3-6. A linkage frame 3-8 is set on the lower end face of the positioning sleeve 3-7. The bottom of the linkage frame 3-8 is fixedly connected to the feeding roller 2.
[0035] The drive limiting assembly 4 includes a support plate 4-1, which is disposed on the side wall of the corrugating machine body 1. The support plate 4-1 is fixedly connected to the drive frame 3-2. The inner side wall of the support plate 4-1 is provided with a pressure plate 4-2, and the feeding roller 2 is in contact with the pressure plate 4-2.
[0036] In some examples, the main structure of the entire equipment, providing the installation foundation and operating platform for various components, must be designed to meet the strength and stability requirements of the carton production process. It must be able to withstand the various forces generated during operation by the feeding roller 2, the drive feeding assembly 3, and the drive limiting assembly 4. Installed on the side wall of the corrugating machine body 1, it is used to convey cardboard into the corrugating machine for subsequent processing. The feeding roller 2 must have suitable surface roughness and friction to ensure that the cardboard does not slip or deviate during conveying, stably feeding the cardboard into the processing area of the corrugating machine. Simultaneously, the material of the feeding roller 2 should have a certain degree of wear resistance to withstand long-term wear. In the cardboard conveying operation, the mounting plate 3-1 is fixed to the side wall of the corrugating machine body 1, serving to support and position the drive frame 3-2. The drive frame 3-2 is installed at the lower end of the mounting plate 3-1, and its shape and structural design should be adapted to the mounting plate 3-1. It is firmly fixed to the mounting plate 3-1 by welding, bolting, or other methods. The drive frame 3-2 provides an installation position for components such as the rotating shaft 3-3, ensuring the structural stability of the entire drive board feeding assembly 3. The rotating shaft 3-3 is installed on the drive frame 3-2 and can rotate flexibly through bearings and other components. A rotating wheel 3-4 is installed at the end of the rotating shaft 3-3. The diameter and material of the rotating wheel 3-4 are specified. The dimensions need to be determined based on actual production requirements. For example, if a faster feeding speed is required, the diameter of the rotating wheel 3-4 can be appropriately increased. Regarding the material, metal can be used to ensure its strength and wear resistance. The rotating wheel 3-4 moves in a circular motion under the drive of the rotating shaft 3-3, providing power to the extension block 3-5 and subsequent components. The extension block 3-5 is located on the side wall of the rotating wheel 3-4 and moves in a circular motion as the rotating wheel 3-4 rotates. The drive shaft 3-6 is mounted on the extension block 3-5, with one end fixedly connected to the extension block 3-5 and the other end fitted with a positioning sleeve 3-7. The positioning sleeve 3-7 can slide to a certain extent on the drive shaft 3-6. To adapt to different work requirements, the lower end face of the positioning sleeve 3-7 is connected to the linkage frame 3-8. By adjusting the position of the positioning sleeve 3-7, the movement trajectory and force of the linkage frame 3-8 can be changed, thereby achieving fine adjustment of the feeding action of the feeding roller 2. The bottom of the linkage frame 3-8 is fixedly connected to the feeding roller 2 by welding, bolt connection or other methods. The linkage frame 3-8 accurately transmits the motion and power transmitted by the positioning sleeve 3-7 to the feeding roller 2, so that the feeding roller 2 performs the feeding operation in a predetermined manner and speed. During the connection process, it is necessary to ensure the strength and stability of the connection part to prevent loosening, breakage or other situations during operation.
[0037] Support plate 4-1 is installed on the side wall of the corrugating machine body 1 and is fixedly connected to the drive frame 3-2, serving to support and stabilize the drive frame 3-2. The shape and size of support plate 4-1 need to be designed according to the structure of drive frame 3-2 and corrugating machine body 1. It is firmly fixed to drive frame 3-2 by welding, bolt connection, etc. Support plate 4-1 also provides installation position for components such as pressure plate 4-2, and is an important support structure of drive limit assembly 4. Pressure plate 4-2 is installed on the inner side wall of support plate 4-1. The feeding roller 2 is in contact with pressure plate 4-2. The material of pressure plate 4-2 should have a certain elasticity and wear resistance, such as rubber, polyurethane, etc. 4-2 Through contact with the feeding roller 2, it plays a role in limiting and buffering the feeding roller 2, preventing excessive deviation or jumping of the feeding roller 2 during operation, and ensuring the stability of paperboard conveying. Connection between the rotating shaft 3-3 and the drive hole and bolt: Both ends of the rotating shaft 3-3 are embedded in the drive hole. One side of the rotating shaft 3-3 is connected to the locking nut 5 by a bolt. The bolt and the rotating shaft 3-3 are connected by a bearing. This connection method makes the rotating shaft 3-3 more stable during rotation. At the same time, through the cooperation of the bolt and the bearing, the position of the rotating shaft 3-3 can be better fixed and adapt to the angle change of the rotating shaft 3-3 during the adjustment process.
[0038] During actual installation, it is necessary to ensure that the components on both sides are installed accurately and symmetrically in order to achieve the best working effect. The number of each component can be reasonably determined according to the size of the corrugating machine body 1, the length of the feeding roller 2, and the actual production needs. Generally speaking, under the premise of ensuring structural stability and working effect, the number of components should be reduced as much as possible to reduce costs and complexity.
[0039] like Figures 1-3 As shown, this embodiment proposes that the end of the driving shaft 3-6 is provided with a connecting piece 3-9, and the connecting piece 3-9 and the rotating shaft 3-3 are movably fitted together.
[0040] In some examples, a connecting piece 3-9 is provided at the end of the drive shaft 3-6. The connecting piece 3-9 is movably fitted with the rotating shaft 3-3. The connecting piece 3-9 plays the role of connecting and transmitting power. At the same time, due to its movable fitting, it can buffer and adjust the impact force and angular deviation during the rotation process to a certain extent, ensuring the smooth operation of the entire drive plate feeding assembly 3.
[0041] For example, such as Figure 1 As shown, the inner sidewall of the support plate 4-1 is provided with a limiting slide 4-3, and both ends of the feeding roller 2 are embedded in the limiting slide 4-3.
[0042] In some examples, the inner wall of the support plate 4-1 is provided with a limiting slide 4-3. Both ends of the feeding roller 2 are embedded in the limiting slide 4-3. The shape and size of the limiting slide 4-3 should be adapted to the end of the feeding roller 2. Its function is to further restrict the movement trajectory of the feeding roller 2, so that the feeding roller 2 can only move within the range specified by the limiting slide 4-3, thereby ensuring the accuracy and stability of the paperboard conveying. The surface of the limiting slide 4-3 should be smooth to reduce the friction of the feeding roller 2 during the movement.
[0043] For example, such as Figure 3 As shown, the side wall of the drive frame 3-2 is provided with a drive slide 4-4, and the inside of the drive slide 4-4 is provided with a sliding hole 4-5. The sliding hole 4-5 is connected to the drive frame 3-2, and the end of the rotating shaft 3-3 is inserted into the inside of the sliding hole 4-5.
[0044] In some examples, the side wall of the drive frame 3-2 is provided with a drive slide 4-4, and the drive slide 4-4 is provided with a sliding hole 4-5 inside. The sliding hole 4-5 is connected to the drive frame 3-2. The shape and size of the drive slide 4-4 need to be designed according to the movement requirements of components such as the rotating shaft 3-3. Its function is to provide sliding space for the end of the rotating shaft 3-3, so that the rotating shaft 3-3 can move within a certain range within the drive slide 4-4, thereby realizing the adjustment of the feeding speed and position of the feeding roller 2.
[0045] For example, such as Figure 3 As shown, a locking nut 5 is provided inside the drive slide 4-4, and the locking nut 5 is fixedly connected to the rotating shaft 3-3.
[0046] In some examples, a locking nut 5 is provided inside the drive slide 4-4. The locking nut 5 is fixedly connected to the rotating shaft 3-3. When it is necessary to adjust the position of the rotating shaft 3-3, the locking nut 5 can be loosened so that the rotating shaft 3-3 can slide into the drive slide 4-4 to a suitable position. Then, the locking nut 5 is tightened to fix the rotating shaft 3-3 in that position. The tightness of the locking nut 5 needs to be adjusted according to the actual working requirements to ensure that the rotating shaft 3-3 is firmly fixed while allowing for flexible adjustment when needed.
[0047] For example, such as Figure 1 As shown, both ends of the rotating shaft 3-3 are embedded in the drive hole. One side of the rotating shaft 3-3 is connected to the locking nut 5 by a bolt. The bolt and the rotating shaft 3-3 are connected by a bearing. There are two mounting pieces 3-1, two drive frames 3-2 and two support pieces 4-1. Several mounting pieces 3-1, two drive frames 3-2 and two support pieces 4-1 are located on opposite side walls of the same side of the corrugating machine body 1.
[0048] In some examples, there are several mounting plates 3-1, drive frames 3-2 and support plates 4-1, and these mounting plates 3-1, drive frames 3-2 and support plates 4-1 are located on opposite side walls of the same side of the corrugating machine body 1. This layout allows the feeding roller 2 to be driven and limited on both sides at the same time, ensuring the balance and stability of the feeding roller 2 during operation.
[0049] In use, the drive feeding assembly 3 is the core power source for conveying cardboard in this adjustable corrugating machine. The power is first transmitted to the rotating shaft 3-3, which is mounted on the drive frame 3-2 and rotates flexibly through the bearing. When the rotating shaft 3-3 rotates, it drives the rotating wheel 3-4 at the end to make a circular motion. The extension block 3-5 on the side wall of the rotating wheel 3-4 moves together with the rotating wheel 3-4, and its circular motion drives the drive shaft 3-6 connected to the extension block 3-5 to move.
[0050] The drive shaft 3-6 is fitted with a positioning sleeve 3-7, which can slide on the drive shaft 3-6 to a certain extent. The linkage frame 3-8 connected to the lower end of the positioning sleeve 3-7 converts the motion transmitted by the positioning sleeve 3-7 into linear motion or a specific trajectory motion, and transmits it to the feeding roller 2. Since the position of the positioning sleeve 3-7 on the drive shaft 3-6 is adjustable, changing the position of the positioning sleeve 3-7 can change the motion trajectory and force of the linkage frame 3-8, thereby precisely controlling the feeding speed, frequency and displacement of the feeding roller 2 to adapt to the conveying needs of different specifications of cardboard. The connecting piece 3-9 at the end of the drive shaft 3-6 is movably fitted with the rotating shaft 3-3, which can buffer the impact force and angular deviation during the rotation process and ensure the smoothness of power transmission.
[0051] The main function of the drive limiting assembly 4 is to ensure the stable operation of the feeding roller 2 and prevent it from deviating or jumping during operation. The support plate 4-1 is fixed to the side wall of the corrugating machine body 1 and connected to the drive frame 3-2, providing stable support for the entire limiting structure. The pressure plate 4-2 on the inner side wall of the support plate 4-1 is in contact with the feeding roller 2. The pressure plate 4-2 is made of elastic and wear-resistant materials, such as rubber and polyurethane. Through elastic buffering, it limits the excessive movement of the feeding roller 2 in the vertical direction and prevents the feeding roller 2 from leaving the normal working position due to vibration and other factors.
[0052] Meanwhile, the limiting slide 4-3 on the inner side wall of the support plate 4-1 further constrains the movement trajectory of the feeding roller 2. The two ends of the feeding roller 2 are embedded in the limiting slide 4-3, so that it can only move in a specific direction within the range specified by the slide, ensuring the accuracy of the cardboard conveying. The cooperation between the drive slide 4-4, sliding hole 4-5, locking nut 5 and rotating shaft 3-3 on the side wall of the drive frame 3-2 realizes the function of adjusting the position and feeding speed of the feeding roller 2. Loosening the locking nut 5 allows the rotating shaft 3-3 to move within the sliding hole 4-5 of the drive slide 4-4. After adjusting to the appropriate position, tightening the locking nut 5 fixes the rotating shaft 3-3, thereby changing the movement radius of the rotating wheel 3-4 and the movement parameters of the feeding roller 2, realizing flexible adjustment of the feeding speed and position.
[0053] In actual operation, the corrugating machine body 1 serves as the basic frame, bearing and fixing all components. The drive feeding assembly 3 continuously provides power to the feeding roller 2, enabling the feeding roller 2 to stably transport the cardboard to the processing area of the corrugating machine. The drive limiting assembly 4 constantly limits and adjusts the feeding roller 2 to ensure that the feeding roller 2 runs according to the predetermined trajectory and parameters.
[0054] When different sizes of cardboard need to be processed, the operator can adjust the position of the rotating shaft 3-3 inside the drive slide 4-4 to change the transmission ratio of the drive feeding assembly 3, thereby adjusting the feeding speed and force of the feeding roller 2. At the same time, the pressure plate 4-2 of the drive limiting assembly 4 and the limiting slide 4-3 will continue to play a limiting role according to the adjustment of the feeding roller 2, ensuring the stability and reliability of the feeding process, and realizing the efficient and accurate completion of the cardboard conveying work in carton production by the adjustable corrugating machine.
