Description

Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, and in particular relates to an adjustable paper pushing device for cardboard box processing. Background Technology

[0002] In the packaging industry, cardboard boxes are a widely used packaging material. With the continuous growth of market demand for cardboard boxes and the increasing requirements for their quality and precision, how to efficiently and accurately complete cardboard box processing has become a problem that needs to be solved in the industry.

[0003] The processing of cardboard boxes usually starts with cardboard and involves several key processes. Among them, the cutting process is an important step in determining the size and shape accuracy of the cardboard box. Before cutting, the cardboard must be accurately positioned at the cutting position to ensure that the cut cardboard box meets the design specifications.

[0004] Currently, in existing technologies, most equipment uses a method of directly setting a cylinder to drive a pusher plate on the cutting equipment to achieve cardboard positioning. This traditional method has many obvious drawbacks. Specifically, the movement of the cylinder is usually based on a fixed stroke and a preset action pattern. This makes it difficult for the existing cylinder pusher plate system to make flexible adjustments when dealing with cardboard of different specifications and sizes. Secondly, in the complex carton processing flow, there are usually multiple other components and devices around the cutting equipment, such as conveying systems and positioning sensors. Since the cylinder pusher plate is directly installed on the cutting equipment, its movement space is limited. During the pusher plate process, it is very easy to interfere with other surrounding components. This interference not only causes the pusher plate movement to be hindered, affecting the positioning accuracy of the cardboard, but may also damage equipment components, increase equipment maintenance costs and downtime, and reduce production efficiency and equipment lifespan.

[0005] In summary, the existing cardboard positioning method based on cylinder-driven pusher plate can no longer meet the needs of the modern carton processing industry for efficient, flexible and precise production. Therefore, practitioners have developed an adjustable paper pushing device for carton processing. Utility Model Content

[0006] The purpose of this invention is to solve the problems of poor flexibility when dealing with different sizes of cardboard and easy interference with surrounding parts in complex processing procedures by using a cylinder to drive a push plate to position the cardboard on the existing cutting equipment. Therefore, this invention provides an adjustable paper pushing device for carton processing.

[0007] The present invention achieves the above objectives through the following technical solution: an adjustable paper pushing device for carton processing, including a supporting base, a supporting platform above the supporting base, a lifting assembly on the front surface of the supporting platform, a horizontal pushing assembly on the lifting assembly, an extension arm on the horizontal pushing assembly, and a leveling push plate assembly at the end of the extension arm.

A pushing motor that drives the rotation of the grooved wheel is arranged on the outer wall of the horizontal pushing body located at one of the grooved wheels. The two sets of grooved wheels are connected by a rubber belt. Pushing guide rails are arranged on both outer walls of the horizontal pushing body. Pushing sliders that cooperate with the two sets of pushing guide rails are arranged on the two sets of pushing guide rails. A pushing base plate is arranged between the two sets of pushing sliders. The bottom of the pushing base plate is fixed to the rubber belt by a connecting plate.

[0009] Furthermore, the bottom of the support base is provided with multiple fixing feet, and the fixing feet are provided with fixing threaded holes.

[0010] Furthermore, the lifting assembly is provided with two sets of lifting guide rails on the support base, each set of lifting guide rails is provided with a corresponding lifting slider, and a lifting base plate is provided between the two sets of lifting sliders. The horizontal pushing assembly is fixed to the top of the lifting base plate. Two sets of bearing platforms are provided between the two sets of lifting guide rails, and a lifting screw is rotatably provided between the two sets of bearing platforms. A lifting motor that drives the lifting screw to rotate is provided at one of the bearing platforms. A ball nut seat is provided on the lifting screw, and the ball nut seat is fixed to the lifting base plate by a connecting piece.

[0011] Furthermore, a protective plate is provided on the support base located at the lifting assembly.

[0012] Furthermore, the outer circumference of the grooved wheel is provided with anti-slip tooth grooves, and the inner surface of the rubber pull belt is provided with a convex ridge structure that cooperates with the anti-slip tooth grooves.

[0013] Furthermore, a tensioning plate is provided on the inner wall of the horizontal pushing body between the two sets of grooved wheels, the tensioning plate being used to cooperate with the rubber belt.

[0014] Furthermore, the alignment push plate assembly includes an alignment motor disposed at the end of the extension arm, the rotation shaft of the alignment motor passes through the extension arm and is provided with a push plate body, and a retaining plate is provided at the bottom of the push plate body.

[0015] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0016] 1. Flexible height adjustment: Through the coordinated action of the lifting component, the horizontal pushing component, and the rotatable leveling push plate component, this device can adapt to cardboard of different specifications and sizes. The lifting component can precisely control the lifting height of the horizontal pushing component to meet the pushing needs of cardboard of different heights. The horizontal pushing component achieves smooth and adjustable horizontal pushing. The leveling motor of the leveling push plate component can drive the push plate body to rotate, and the bottom clamping plate can firmly clamp the edge of the cardboard and effectively adjust the angle of the cardboard, which greatly improves the adaptability of the device to various types of cardboard and solves the problem of poor flexibility of traditional cylinder push plates.

[0017] 2.

The support base is firmly installed with fixed feet, providing a stable foundation for the entire device. The protective plate is set at the lifting assembly to further prevent interference between the internal structure of the device and the outside world, ensuring smooth paper pushing process, reducing the risk of equipment damage, reducing downtime caused by interference, and extending the service life of the equipment.

[0018] 3. Improved positioning accuracy: In the horizontal pushing assembly, the anti-slip grooves on the outer circumference of the grooved wheel and the raised ridges on the inner surface of the rubber belt fit tightly together to prevent transmission slippage. The tensioning plate tensions the rubber belt to ensure stable power transmission, making the movement of the pushing base plate more precise. This results in more accurate horizontal pushing of the cardboard. The aligning push plate assembly can finely adjust the angle of the cardboard to ensure that the cardboard is in the correct position before cutting, meeting the high precision requirements of the modern carton processing industry, reducing scrap rate, and improving product quality.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Combination Figure 1-3 The adjustable paper pushing device for carton processing shown mainly consists of a support base 1 as the basic load-bearing part of the entire device. The support base 1 is made of high-strength steel in one piece, which has good stability and load-bearing capacity. A support platform 2 is firmly set on top of it. The surface of the support platform 2 has extremely high flatness to ensure the installation accuracy of subsequent components.

[0027] It is worth noting that a lifting assembly 3 is provided on the front surface of the support base 2. The lifting assembly 3 includes two parallel and perpendicular lifting guide rails 301 installed on the front surface of the support base 2. The surfaces of these two lifting guide rails 301 are subjected to high-precision grinding to ensure smooth movement. Lifting sliders 302 are fitted and installed on the two lifting guide rails 301 respectively, and the two sets of lifting sliders 302 are connected and fixed by a thick lifting base plate 303. The lifting base plate 303 is also made of high-quality steel and has sufficient strength and rigidity to provide a reliable support platform for the subsequent installation of the horizontal pushing assembly 4. The system is equipped with two sets of bearing platforms 304, each containing its own bearings. A high-precision lifting screw 305 is rotatably mounted between the two sets of bearing platforms 304. A lifting motor 306 is installed at one of the bearing platforms 304 to drive the lifting screw 305. A ball nut seat 307 is fitted onto the lifting screw 305 and is precisely matched with it. The ball nut seat 307 is firmly fixed to the lifting base plate 303 by a carefully designed connector 308. When the lifting motor 306 drives the lifting screw 305 to rotate, the ball nut seat 307 drives the lifting base plate 303 and the horizontal push assembly 4 mounted on it to achieve precise lifting and lowering movements.

[0028] A horizontal pushing component 4 is mounted on top of the lifting component 3. The core of the horizontal pushing component 4 is a hollow horizontal pushing body 401, which is made of high-strength aluminum alloy. This material effectively reduces the overall weight while ensuring structural strength. Both ends of the horizontal pushing body 401 have grooved wheels 402 that rotate via high-precision bearings. These wheels are injection molded from special engineering plastics, making them lightweight, high-strength, and wear-resistant. Anti-slip grooves are carefully designed and machined on their outer circumference. A pushing motor 403 is mounted on the outer wall of the horizontal pushing body 401 at one of the grooved wheels 402. The pushing motor 403 is fixed to the horizontal pushing body 401 via a specially designed motor mounting bracket. A shock-absorbing rubber pad is placed between the motor mounting bracket and the horizontal pushing body 401 to reduce the impact of vibrations generated during motor operation. A special rubber strap connects the two sets of grooved wheels 402. The inner surface of the rubber belt 404 is provided with a convex rib structure that matches the anti-slip tooth groove of the grooved wheel 402, ensuring that slippage will not occur during transmission and achieving stable and reliable power transmission. High-precision push guide rails 405 are installed on both outer side walls of the horizontal push body 401. The surface of the push guide rails 405 is hardened to further improve its wear resistance. Each of the two sets of push guide rails 405 is provided with a push slider 406 that fits closely with it. A push base plate 407 is installed between the two sets of push sliders 406. The push base plate 407 has sufficient strength and rigidity to support and push the extension arm 5 to be connected later. The bottom of the push base plate 407 is fixed to the rubber belt 404 by a sturdy connecting plate 408. When the push motor 403 drives the grooved wheel 402 to rotate, the rubber belt 404 drives the connecting plate 408 and the push base plate 407 to make a smooth horizontal linear movement along the push guide rail 405.

[0029] An extension arm 5 is installed on the horizontal pushing component 4. The extension arm 5 is firmly connected to the pushing base plate 407 of the horizontal pushing component 4 through a specially designed connection structure. The connection structure adopts a double fixing method of bolts and positioning pins to ensure the stability and reliability of the connection.

[0030] A straightening push plate assembly 6 is provided at the end of the extension arm 5. The straightening push plate assembly 6 includes a straightening motor 601 installed at the end of the extension arm 5. The rotation shaft of the straightening motor 601 passes through the extension arm 5. A push plate body 602 is fixedly installed at the end of the rotation shaft. The push plate body 602 is made of high-strength plastic and the surface is treated with anti-slip. A clamping plate 603 is also provided at the bottom of the push plate body 602. The clamping plate 603 is made of elastic rubber material, which can firmly clamp the edge of the cardboard when pushing it, without damaging the cardboard. Driven by the straightening motor 601, the push plate body 602 can achieve precise angle adjustment, thereby performing a precise straightening operation on the cardboard.

[0031] In this embodiment, the bottom of the support base 1 is evenly distributed with multiple carefully designed fixing feet. These fixing feet are made of high-strength cast steel in one piece, which has excellent pressure resistance and deformation resistance. The bottom surface of each fixing foot has been finely machined to ensure that the contact area with the ground is large enough and fits tightly, thereby providing stable support. Multiple fixing threaded holes are precisely opened on the top of the fixing feet to fit high-strength anchor bolts, which can firmly fix the support base 1 to the ground, effectively preventing displacement or shaking due to vibration or external force during equipment operation, and providing a solid and reliable foundation for the stable operation of the entire adjustable paper pushing device for carton processing.

[0032] In this embodiment, a protective plate 7 is provided in the area of ​​the support base 2 corresponding to the lifting component 3. The protective plate 7 is made of acrylic material, which has good transparency, making it convenient for operators to observe the operation status of the lifting component 3 in real time. At the same time, it has excellent impact resistance and can effectively resist accidental collisions of foreign objects to the lifting component 3.

[0033] In this embodiment, a tensioning plate 409 is specially provided on the inner wall of the horizontal pushing body 401 between the two sets of grooved wheels 402.

[0034] The tension plate 409 and the rubber belt 404 are matched in bending curvature during normal operation. This ensures that if the rubber belt 404 becomes loose after prolonged use and is not maintained in time, it will be interfered with by the tension plate 409 and will not sink excessively, thus affecting subsequent operation. This provides sufficient time for maintenance and improves the reliability of the entire adjustable paper pusher.
