Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paperboard processing equipment, in particular to a paperboard processing equipment cutter beam assembly with angle and position adjustment functions. BACKGROUND

[0002] In the field of paperboard processing, such as slotting machines, slitting machines and other paperboard processing equipment, the performance of the cutter beam assembly is crucial to the efficiency and quality of the entire production process. For example, in the actual operation process of a traditional paperboard slotting machine, due to errors in paper size and shape, the cutter position needs to be adjusted, which is called cutter adjustment. In the early days, manual cutter adjustment was commonly used, and the operator adjusted the cutter position manually to adapt to different paper requirements. However, this method has many drawbacks. First, manual adjustment takes a long time, which seriously affects production efficiency and cannot meet the needs of modern high-efficiency production. Second, the accuracy of manual adjustment is poor, making it difficult to ensure the accuracy of slotting and resulting in uneven product quality. Third, manual cutter adjustment during equipment operation poses a significant safety risk to operators, and any carelessness can lead to safety accidents.

[0003] To solve these problems of manual cutter adjustment, a selective cutter adjustment method was developed. The principle is to use a displacement assembly that can selectively cooperate with different cutters in the cutter beam to control the movement of the cutters. In theory, this method can better meet production needs. However, in actual application, because it cannot achieve synchronous movement of multiple cutters, the flexibility and convenience of adjustment are greatly compromised. For example, during adjustment, when the position of the first cutter is adjusted, the position of the second cutter may need to be adjusted again, and this process is repeated, making the entire adjustment process lengthy and making it difficult to ensure the final adjustment accuracy, which greatly limits the improvement of production efficiency and the stability of product quality.

[0004] Currently, the cutter beam advances (i.e., makes contact with the paperboard for processing) and retreats (i.e., does not contact the paperboard) by direct drive of the air cylinder, i.e., the main shaft of the air cylinder is directly connected and driven by the cutter beam. This direct drive method has some problems. On the one hand, if the air cylinder is unstable, it may cause instability of the cutter beam position, affecting processing accuracy and product quality. On the other hand, direct drive causes the air cylinder to be under heavy stress, which not only accelerates wear and tear of the air cylinder but also may shorten its service life, increasing maintenance costs and downtime of the equipment. In view of the above-mentioned deficiencies of the prior art, it is particularly urgent to develop a new cutter beam assembly, CONTENT OF THE INVENTION

[0005] The purpose of this application is to overcome at least one deficiency in the existing technology and provide a cutter beam assembly for cardboard processing equipment with angle and position adjustment functions. This cutter beam assembly can achieve precise displacement of the cutter beam in both the lateral and longitudinal directions, improving processing accuracy and efficiency. Specifically, through the coordinated operation of the lateral displacement mechanism and the longitudinal displacement actuator, the cutter beam assembly can flexibly adjust the position and angle of the cutter beam to meet different processing requirements. Furthermore, this cutter beam assembly also has advantages such as compact structure, simple operation, and convenient maintenance, effectively reducing equipment downtime and maintenance costs, and improving production efficiency and product quality.

[0006] To achieve the above objectives, this application discloses a blade beam assembly for a cardboard processing equipment with angle and position adjustment functions. The blade beam assembly includes: a load-bearing base, a transverse displacement mechanism, and at least one set of longitudinal displacement actuators.

[0007] The longitudinal displacement actuator is mounted on the support base, and at least one machining tool is provided on it;

[0008] The longitudinal displacement actuator includes a guide assembly, a load-bearing unit that slides along the guide assembly, and a transmission assembly that drives the load-bearing unit to reciprocate.

[0009] The lateral displacement mechanism is linked to the supporting base to achieve linear displacement along the lateral direction.

[0010] The lateral displacement mechanism is provided with a lateral slide rail pair between itself and the bearing base, which is used to constrain the bearing base to make linear displacement in the lateral direction perpendicular to the longitudinal direction.

[0011] Furthermore, the lateral displacement mechanism includes a rigid base assembly fixedly connected to an external mechanism, with a horizontally arranged linear guide rail on its surface. The working surface of the guide rail forms a sliding pair with the bearing base. A cylinder fixed to the side wall of the base cooperates with a wedge-shaped slider connected to the end of the piston rod and a slanted guide block provided on the bearing base. The cylinder drives the wedge-shaped slider to move vertically relative to the bearing base, decomposing the vertical driving force into a horizontal thrust, thereby realizing the lateral displacement of the bearing base.

[0012] Furthermore, the transmission component of the longitudinal displacement actuator includes a ball screw pair and a drive servo motor. The ball screw pair is connected to the output end of the drive servo motor via a coupling, and its screw thread is kinematically coupled with the ball nut of the bearing unit. The longitudinal fine-tuning and positioning of the bearing unit is achieved by controlling the speed and direction of the servo motor. The guide component is a linear guide rail that cooperates with the bearing unit. When there are multiple longitudinal displacement actuators, the linear guide rails of each actuator are arranged in parallel with the ball screw pair. The bearing unit is equipped with a quick-change tool mounting base, which forms a detachable assembly connection with the machining tool.

[0013] Further, the bearing base has multiple longitudinal displacement execution mechanisms arranged in mirror symmetry in the same axial position interval; the bearing unit of each longitudinal displacement execution mechanism is independently configured with a machining tool, and the differential programming control of the tool position is realized through an independent servo driving system, so that the tool density in the single axial position interval is significantly increased and the movement is interference-free.

[0014] The adjustable paperboard processing equipment tool beam assembly of the present application can realize accurate displacement of the tool beam in the transverse and longitudinal directions through the arrangement of the transverse displacement mechanism and the longitudinal displacement execution mechanism, thereby improving the processing precision and efficiency. At the same time, the mirror symmetry arrangement of the bearing base and the independent servo driving system significantly increase the tool density and realize interference-free movement, thereby further improving the processing quality and production efficiency. In addition, the design of the quick-change tool mounting base facilitates the replacement and maintenance of the tools and reduces the downtime of the equipment.

[0027] The following is an example of the adjustable cardboard slotting machine blade assembly:

[0028] See attached document Figs. 1 to 4 This embodiment provides an adjustable cardboard slotting machine blade beam assembly, mainly composed of a supporting base 1, a transverse displacement mechanism 2, and at least one set of longitudinal displacement actuators 3. These components cooperate with each other to achieve precise cardboard slotting. The specific structure and working principle of this embodiment will be described in detail below.

[0029] In this embodiment, the supporting base 1 serves as the fundamental support structure for the entire cutter beam assembly. It is made of steel or aluminum alloy, possessing good rigidity and stability, capable of withstanding various mechanical forces generated during the cutter beam assembly process, ensuring the operational accuracy of the entire device. The shape of the supporting base 1 is designed as a long strip based on the actual installation space and usage requirements of the grooving machine.

[0030] The transverse displacement mechanism 2 is arranged in linkage with the carrying base 1, and is used to realize linear displacement of the carrying base 1 in the transverse direction, i.e. to realize feeding and retreating. The transverse displacement mechanism 2 comprises a rigid base assembly 201 fixedly connected with an external rack (not shown in the figure), the surface of the base assembly 201 is provided with linear guides arranged in the transverse direction, and the working surface of the linear guides forms a sliding pair with a sliding block provided on the carrying base 1. A gas cylinder 202 is fixed to the side wall of the base assembly 201, and the piston rod of the gas cylinder 202 is connected with a wedge-shaped sliding block 203 at the end, which cooperates with a slant groove guide block 101 provided on the carrying base 1. The wedge-shaped sliding block 203 is driven by the gas cylinder 202 to move vertically relative to the carrying base 1, and the slant groove of the slant groove guide block 101 is used to decompose the vertical driving force into horizontal thrust, so as to push the carrying base 1 to accurately displace along the transverse linear guide 202. The transverse guide rail pair restricts the carrying base 1 to move only in the transverse direction, and avoids deflection or deviation.

[0031] In actual implementation, two transverse displacement mechanisms 2 are provided symmetrically at both ends of the carrying base 1, and the two transverse displacement mechanisms 2 work synchronously.

[0032] In the embodiment, at least one set of longitudinal displacement execution mechanism 3 is arranged on the carrying base 1, which is used to realize slitting or partial paperboard processing.

[0033] Further, the longitudinal displacement execution mechanism 3 is arranged in mirror symmetry in the longitudinal direction of the carrying base 1, two or more longitudinal displacement execution mechanisms 3 are arranged in the same axial position interval, and the guide assembly and the transmission assembly of each execution mechanism are distributed in radial symmetry along the carrying base 1. This symmetrical arrangement can realize independent adjustment of high-density cutters.

[0034] The longitudinal displacement execution mechanism 3 is movably connected with the carrying base 1, and the number of the longitudinal displacement execution mechanism 3 in the transverse direction is set to one or more according to actual processing requirements. When multiple sets of longitudinal displacement execution mechanisms 3 are arranged, each execution mechanism is independent of each other and does not interfere with each other, and can realize simultaneous longitudinal displacement adjustment of multiple processing cutters 4, thereby improving the slitting efficiency.

[0035] More specifically, the longitudinal displacement execution mechanism 3 comprises a guide assembly 303, a carrying unit 301 sliding along the guide assembly 303, and a transmission assembly 304 driving the carrying unit 301 to reciprocate. Each carrying unit 301 is independently arranged with at least one working cutter 4, and the differential adjustment of the longitudinal position of each cutter is realized by an independently controlled driving servo motor 302. Specifically, the carrying unit 301 is provided with a quick-change cutter mounting base (aluminum alloy material), which is detachably connected with the working cutter 4 through a bolt pair. The working cutter 4 is made of hard alloy material, which ensures the cutting performance.

[0036] The guide assembly 303 adopts linear guide rails, the guide rail surface is in low friction cooperation with the sliding part of the bearing unit; the transmission assembly 304 contains a ball screw pair and a driving servo motor 302. The ball screw pair is connected to the output end of the servo motor 302 through a shaft coupling, and the screw thread part is in motion coupling with the ball nut of the bearing unit 301. By controlling the rotating speed and direction of the servo motor 302, the bearing unit 301 is driven to move longitudinally along the guide rail, realizing accurate positioning of the tool. When multiple sets of actuators 3 are arranged in parallel, the linear guide rails and the ball screw pairs are arranged in parallel, ensuring independent movement without interference.

[0037] While exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are intended to be included within the scope of the present disclosure as defined by the claims.
