Description

TECHNICAL FIELD

[0001] The present application relates to the field of paperboard processing equipment, in particular to a belt pulley assembly with position adjustment function for paperboard processing equipment. BACKGROUND

[0002] In the modern paperboard processing industry, the performance and efficiency of paperboard processing equipment (such as slitting machines, slotting machines, etc.) have an important impact on the entire production process. Among them, the belt type paperboard conveying device is widely used in various paperboard processing equipment due to its simple structure, low cost and easy maintenance. The device mainly drives the belt to run through the belt pulley, so as to convey the paperboard to be processed or the processed paperboard, so as to realize the continuous processing of the paperboard. However, with the continuous improvement of the production efficiency, product quality and automation degree of the paperboard processing industry, the existing belt type paperboard conveying device gradually exposes some problems.

[0003] The existing belt pulley assembly for paperboard processing equipment mostly adopts manual adjustment mode, which has many shortcomings in actual operation. First, in terms of the personal safety of the operator, when manually adjusting the position of the belt pulley, the operator needs to directly contact the moving parts of the equipment, which increases the risk of injury. Especially when adjusting during the operation of the equipment, the operator may be injured due to negligence or equipment failure. Secondly, in terms of adjustment accuracy, manual adjustment mode is difficult to achieve high-precision positioning. Due to the differences in experience and skill level of the operators, as well as the mechanical clearance and elastic deformation in the process of manual adjustment, the position adjustment accuracy of the belt pulley is low, which cannot meet the needs of high-precision paperboard processing. In addition, the manual adjustment mode also affects the automation degree of the paperboard processing equipment. In modern paperboard processing production lines, the automation degree is directly related to the stability of production efficiency and product quality. Manually adjusting the position of the belt pulley not only increases the working intensity of the operator, but also may increase the downtime during production, thereby affecting the running efficiency of the entire production line.

[0024] The following is an example of a pulley assembly for a cardboard slotting machine:

[0025] See attached document Figs. 1-3 This embodiment relates to a pulley assembly for a cardboard processing equipment with a position adjustment function. Its overall structure is ingenious and its function is practical. It is mainly composed of a first linear guide rail 1 and a second linear guide rail 2 arranged in parallel with each other. The components cooperate with each other to achieve precise position adjustment and stable transmission function.

[0026] In this embodiment, the first linear guide 1 adopts a rectangular cross-section design. In the working state, the radial load direction of the sliding base 3 is orthogonal to the axial direction of the first linear guide 1. This ingenious design can form a self-locking effect, effectively maintain the positional stability of the sliding base 3, and prevent the sliding base 3 from being displaced due to external forces during operation, thereby ensuring the operating accuracy of the entire device.

[0027] Specifically, the sliding base 3 forms a sliding pair with the first linear guide rail 1 through a linear bearing. The use of the linear bearing enables the sliding base 3 to slide smoothly and stably on the first linear guide rail 1, while also having sufficient load-bearing capacity to adapt to the various forces generated by cardboard processing equipment such as cardboard slotting machines and slitting machines during operation.

[0028] In this embodiment, at least one pulley 4 is provided on the sliding base 3. The pulley 4 is used to adjust the position of the belt used for conveying the cardboard. Its material is usually high-strength engineering plastic or metal material, such as nylon or aluminum alloy, to ensure good wear resistance and reliability at high speed.

[0029] In this embodiment, at least one set of axially displaceable wheel position adjustment mechanisms 5 are provided on the second linear guide rail 2. These wheel position adjustment mechanisms 5 are the key part of this component to realize the position adjustment function. They include an axial movement unit 7 controlled by a drive device 6.

[0030] It should be understood that, in practice, the drive device 6 has various specific forms in different embodiments. Specifically, the drive device 6 shown in the accompanying drawings of this embodiment is a synchronous belt linear module, with the following specific structure: a motor 601 fixed to the end of the second linear guide rail 2, the motor 601 being firmly connected to the end of the guide rail via a mounting base, and its output shaft being coaxially driven with the active synchronous pulley 602; the active synchronous pulley 602 and the driven synchronous pulley 603 being respectively mounted on both ends of the second linear guide rail 2 via bearing seats, and the axes of the two pulleys being parallel to the second linear guide rail 2; a synchronous belt 604 being sleeved between the active synchronous pulley 602 and the driven synchronous pulley 603, and being rigidly connected to the axial movement unit 7 via a synchronous belt pressure plate; when the motor 601 is driven, the synchronous belt 604 drives the axial movement unit 7 to perform linear displacement along the second linear guide rail 2, thereby providing the motion basis for adjustment.

[0031] In another embodiment not shown in the accompanying drawings, the drive device 6 is a combination of a servo motor and a ball screw pair. The servo motor is fixed to the end of the second linear guide 2 via a flange, and the output shaft is coaxially connected to the ball screw via a coupling. The ball screw and nut pair is mounted on the ball screw, and the internal thread of the ball screw and nut pair matches the external thread of the ball screw. The two achieve a tight mechanical connection through the meshing of the threads. The ball screw and nut pair is rigidly connected to the axial movement unit 7. This structure can provide higher precision and rigidity and is suitable for occasions with high position adjustment accuracy requirements.

[0032] In another embodiment not shown in the accompanying drawings, the drive device 6 is an electric push rod or a telescopic cylinder connected to the axial movement unit 7. It has a simple structure and low cost, but it is slightly inferior to the first two in terms of control accuracy and stability. It is suitable for some application scenarios where the adjustment accuracy requirements are not particularly high.

[0033] In this embodiment, the wheel adjustment mechanism 5 further includes a telescopic actuator 8 disposed on the axial movement unit 7, and a drive block 9 connected to the end of the telescopic actuator 8. The telescopic actuator 8 can be an electric cylinder, a pneumatic cylinder, or other similar linear drive device, and its function is to drive the drive block 9 to perform telescopic movement in the axial direction to achieve connection and engagement with the sliding base 3.

[0034] To achieve wheel position adjustment, the sliding base 3 and the drive block 9 are provided with complementary fitting structures at corresponding positions. These complementary fitting structures consist of mutually cooperating protrusions and grooves. The protrusions are guide ribs with trapezoidal cross-sections, and the grooves are matching dovetail groove structures. This design enables precise positioning and reliable connection between the sliding base 3 and the drive block 9. During wheel position adjustment, the drive block 9 engages with the groove of the sliding base 3 through its protrusions. When the wheel position adjustment mechanism 6 moves, it drives the sliding base 3 to move axially along the first linear guide rail 1, thereby achieving wheel position adjustment.

[0035] In practical applications, when slotting or slitting of cardboard is required, the axial movement unit 7 of the wheel position adjustment mechanism 5 is first moved to a suitable position by the drive device 6, based on the cardboard's dimensions and the slotting or slitting requirements. Then, the telescopic actuator 8 is activated, causing the protrusion of the drive block 9 to engage with the groove of the sliding base 3, thus moving the sliding base 3 along the first linear guide rail 2 and adjusting the relative position of the pulleys. During the adjustment process, the self-locking effect of the first linear guide rail 1 ensures the positional stability of the sliding base 3, allowing it to be positioned in the desired location after adjustment.

[0036] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
