Description

Technical Field

[0001] This invention relates to the field of corrugated paper production equipment technology, and more specifically, to a corrugated paper composite equipment for corrugated carton processing. Background Technology

[0002] In the corrugated cardboard box manufacturing process, corrugated paper laminating equipment is the key equipment for achieving the bonding and forming of multiple layers of corrugated paper. Its core component is the pressing roller, which, through the pressing action of the roller, tightly bonds the multiple layers of corrugated paper, ensuring the structural strength of the cardboard box. Existing corrugated paper laminating equipment mostly uses integrally structured pressing rollers, equipped with only a single rotary drive source and adjustment mechanism, which can meet the processing requirements of conventional full-width uniform pressing.

[0003] However, in some special customized processing needs, such as home appliance packaging, where it is necessary to thicken corrugated paper locally (such as the long side load-bearing area) and perform conventional differential pressing on the remaining areas, the existing integral pressing roller structure cannot meet such needs. It is difficult to achieve targeted pressing on different areas of corrugated paper, resulting in the need to add auxiliary processing steps and increasing the processing complexity.

[0004] Therefore, there is an urgent need for a corrugated paper composite equipment that can adapt to the above-mentioned special processing requirements and achieve localized differentiated pressing. Summary of the Invention

Detailed Implementation

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or mechanisms may be omitted, substituted, or added as needed in the various examples. Furthermore, features described in some examples may be combined in other examples.

[0029] Please refer to the following: Figures 1 to 5A corrugated paper composite equipment for corrugated cardboard box processing includes: a frame 10, a rolling mechanism 20, a detection mechanism 30, and a control terminal; the frame 10 is the installation foundation of the equipment and is used to support the rolling mechanism 20, the detection mechanism 30, and other components. It is made of high-strength steel welded together to ensure the structural stability of the equipment during operation.

[0030] The pressing mechanism 20 is mounted on the frame 10 and includes a pressing assembly and a conveying assembly. The pressing assembly includes an upper pressing roller and a lower pressing roller 210. The lower pressing roller 210 is rotatably mounted on the frame 10, with its axis perpendicular to the corrugated paper conveying direction, and is used to cooperate with the upper pressing roller to press the corrugated paper. The upper pressing roller includes at least two roller segments of different lengths (preferably two, a long roller segment and a short roller segment, to adapt to the local thickening requirements of different packaging). Each roller segment is equipped with an independent rotary drive, a telescopic drive, and a lateral drive assembly. The rotary drive is used to drive... The corresponding roller segment rotates around its own axis, and the friction between the roller segment and the corrugated paper drives the corrugated paper to move along the conveying direction. The telescopic drive component is used to drive the corresponding roller segment to rise and fall in a direction perpendicular to the conveying direction of the corrugated paper, thereby adjusting the pressing gap between the upper and lower pressing rollers 210. The transverse drive component is used to drive each roller segment to switch between splicing and separation states. In the splicing state, the outer circumference of each roller segment is flush, forming a complete pressing surface, which meets the conventional full-width pressing requirements. In the separation state, each roller segment is staggered along the axial direction, and the pressing parameters can be adjusted independently for different areas.

[0031] Specifically, each roller segment includes a slide block 201 slidably mounted on the frame 10, a guide rod 202 rotatably mounted on the slide block 201, and a roller body 203 slidably mounted on the guide rod 202. The frame 10 is provided with a vertical groove adapted to the slide block 201 to realize the lifting and lowering of the roller segment along the direction perpendicular to the corrugated paper conveying direction. The guide rod 202 is a regular hexagonal prism, and the inner hole of the roller body 203 is a regular hexagonal hole adapted to the guide rod 202. Through the cooperation of the hexagonal structure, the roller body 203 is restricted from rotating independently relative to the guide rod 202, ensuring that the guide rod 202 drives the roller body 203 to rotate synchronously. The guide rod 202 is rotatably connected to the slide block 201, and its axis coincides with the axis of the roller body 203. It is used to provide guidance for the lateral movement of the roller body 203 and restrict the independent rotation of the roller body 203. The roller body 203 is slidably sleeved on the guide rod 202 and can move along the axial direction of the guide rod 202 to realize splicing or separation with other roller segments.

[0032] The rotary drive is a servo motor 204 mounted on the slide 201. The output end of the servo motor 204 is connected to one end of the guide rod 202. When the servo motor 204 starts, it drives the guide rod 202 to rotate, and the guide rod 202 drives the roller body 203 to rotate synchronously, realizing the conveying and rolling of corrugated paper. Since each roller section is equipped with an independent servo motor 204, the speed of each roller section can be adjusted through the control terminal to ensure the synchronization of conveying.

[0033] The telescopic drive component is a first servo electric cylinder 205 mounted on the frame 10. The telescopic end of the first servo electric cylinder 205 is fixedly connected to the slide block 201 through a flange. When the first servo electric cylinder 205 telescopically extends or retracts, it drives the slide block 201 to rise and fall along the linear slide rail of the frame 10, thereby driving the roller body 203 to rise and fall synchronously, so as to realize the adjustment of the pressing gap.

[0034] The lateral movement drive assembly includes a second servo cylinder 206 mounted on a slide block 201 and a connecting ring 207 rotatably sleeved on the end of the roller body 203. The telescopic end of the second servo cylinder 206 is fixedly connected to the connecting ring 207. The connecting ring 207 is rotatably engaged with the end of the roller body 203 through a bearing to ensure that the roller body 203 does not drive the second servo cylinder 206 to rotate synchronously when it rotates. When the second servo cylinder 206 telescopically extends or retracts, it pushes the roller body 203 to move axially along the guide rod 202 through the connecting ring 207, thereby realizing the splicing or separation of each roller segment.

[0035] The conveying assembly includes an upper limit roller 208 with adjustable height that is rotatably mounted on the frame 10, and multiple conveying rollers 209 that are rotatably mounted side by side on the frame 10. The multiple conveying rollers 209 are driven by a synchronous drive source 211 (such as a geared motor). The upper limit roller 208 is connected to the frame 10 through an adjustment mechanism and its height can be adjusted according to the thickness of the corrugated paper. Together with the conveying rollers 209, it can achieve stable conveying of the corrugated paper and avoid deviation or wrinkles during the conveying process.

[0036] The detection mechanism 30 is used to collect corrugated paper parameters and roller segment operating parameters. Specifically, it includes pressure sensors 301 installed on each roller segment and thickness sensors 302 installed at the input end of the corrugated paper. The pressure sensors 301 are embedded in the outer circumferential surface of the roller body 203 or installed in the bearing seat of the roller body 203 to collect the pressing force between the roller body 203 and the corrugated paper in real time. The thickness sensor 302 is a laser thickness sensor 302, installed on the frame 10 at the input end of the corrugated paper, to collect the thickness of the corrugated paper entering the pressing area in real time. In addition, the detection mechanism 30 also includes speed sensors installed at the output end of each servo motor to collect the speed parameters of each roller segment in real time and transmit them to the control terminal.

[0037] The control terminal is connected to the rolling mechanism 20 and the detection mechanism 30 respectively (the connection can be achieved through a data cable or wireless communication module). It has a preset parameter template library and is configured to: control the telescopic drive of each roller segment to adjust the pressing gap of the corresponding roller segment according to the parameter template library and the acquisition signal of the detection mechanism 30, and perform closed-loop adjustment of the operating parameters of each roller segment based on the feedback signal of the detection mechanism 30.

[0038] The parameter template library pre-stores the roller segment status (splicing / separation), roller segment pressing gap, and roller segment pressing force parameters corresponding to different corrugated cardboard specifications. For example, the "refrigerator packaging long side thickened template" corresponds to "long roller segment separation, pressing gap 2mm, pressing force 0.35MPa; short roller segment splicing, pressing gap 3mm, pressing force 0.2MPa". At the same time, the control terminal supports user-defined parameter templates and updates them to the parameter template library to adapt to personalized production needs.

[0039] The closed-loop adjustment at the control end specifically includes: correcting the pressing gap of the corresponding roller segment based on the acquisition signal of the thickness sensor 302 (if the acquired corrugated paper thickness is greater than the preset value, the telescopic drive is controlled to drive the roller body 203 to rise, increasing the pressing gap; if the thickness is less than the preset value, the roller body 203 is controlled to fall, decreasing the pressing gap); and correcting the output torque of the telescopic drive of the corresponding roller segment based on the acquisition signal of the pressure sensor 301 (if the acquired pressing force is less than the preset value, the output torque of the first servo cylinder 205 is increased, increasing the pressing pressure; if the pressing force is greater than the preset value, the output torque is decreased to avoid crushing the corrugated paper).

[0040] Furthermore, a roll material mounting mechanism 40 is provided on one side of the frame 10. The roll material mounting mechanism 40 includes an unwinding drive assembly 401 mounted on the frame 10 and a movable mounting frame 402 detachably mounted on one end of the frame 10. One end of the mounting frame 402 is connected to the unwinding drive assembly 401 for transmission. The mounting frame 402 is used to mount the corrugated paper roll. The unwinding drive assembly 401 (such as an unwinding motor) drives the movable mounting frame 402 to rotate, thereby achieving stable unwinding of the corrugated paper. The detachable design facilitates the replacement of the roll material.

[0041] The specific working process of the corrugated paper composite equipment designed in this invention is as follows:

[0042] Step 1, Equipment Debugging and Template Selection:

[0043] The operator installs the lower corrugated paper roll onto the movable mounting frame 402 of the roll installation mechanism 40. Before entering the pressing area, the free end of the lower corrugated paper roll is pre-bonded to the free end of the upper corrugated paper roll by the guide mechanism. The roll passes sequentially between the conveying roller 209 and the upper limit roller 208 of the conveying assembly, and below the thickness sensor 302 at the corrugated paper input end. Finally, the roll is delivered between the upper pressing roller and the lower pressing roller 210 of the rolling assembly. Then, the corresponding control parameters are selected on the operation interface of the control terminal.

[0044] Step 2, Roll segment status switching and parameter initialization:

[0045] After receiving the template selection signal, the control terminal first sends a control command to the transverse drive component: control the second servo electric cylinder 206 corresponding to the long roller segment to retract, push the long roller segment to move axially along the guide rod 202, and form a preset distance with the short roller segment, while the short roller segment maintains the splicing reference position unchanged;

[0046] Subsequently, the control terminal sends instructions to the first servo cylinder 205 of each roller segment: drive the slide block 201 of the long roller segment to descend along the slide rail of the frame 10, so that the gap between the long roller segment and the lower pressing roller 210 is adjusted to a preset distance; drive the slide block 201 of the short roller segment to descend, so that the gap between the short roller segment and the lower pressing roller 210 is adjusted to a preset distance; at the same time, start the rotation drive of each roller segment, and the control terminal collects the real-time rotation speed of each roller segment through the speed sensor, and adjusts the rotation speed of the long roller segment and the short roller segment to be consistent to ensure the synchronous conveying.

[0047] Step 3, Real-time Detection and Closed-Loop Adjustment:

[0048] The equipment is started for composite processing. The drive source of the conveying component drives multiple conveying rollers 209 to rotate synchronously, which, together with the upper limit roller 208, smoothly conveys the corrugated paper to the rolling area. During this process:

[0049] The thickness sensor 302 collects the thickness parameters of the corrugated paper in real time and transmits the collected signal to the control terminal. The control terminal compares the collected thickness with the preset thickness of the template. If the actual thickness is found to deviate from the preset value, it immediately sends an adjustment command to the first servo cylinder 205 of the long roller section to control the long roller section to rise by the corresponding distance, and adapts and corrects the pressing gap to avoid the double-layer corrugated paper being crushed.

[0050] The pressure sensors 301 of the long and short roller sections collect the pressing force signal in real time. If the real-time pressing force of the long and short roller sections is found to deviate from the preset pressure value, the control terminal immediately controls the output torque of the corresponding first servo cylinder 205 until the pressure value of the long and short roller sections meets the preset value and the parameters remain stable.

[0051] Step 4, Continuous processing and parameter recording:

[0052] Once the equipment enters continuous processing mode, the control terminal continuously receives signals from the detection mechanism 30 and dynamically adjusts the pressing gap and pressing force of each roller segment in a closed loop. During processing, if there is fluctuation in the corrugated paper thickness or abnormal pressing force, the control terminal immediately corrects the parameters and issues an early warning. After production is completed, the control terminal automatically records the batch information of this processing, the adjustment parameters of each roller segment, and the finished product qualification rate, and updates them to the parameter template library to provide optimized parameters for subsequent processing of the same specifications.

[0053] Step 5, Specification Switching and Equipment Shutdown:

[0054] When it is necessary to switch to processing other specifications of corrugated paper, the operator only needs to select the corresponding template on the control terminal, and the equipment will automatically repeat the process of steps two to four to complete the switching of roller segment status and parameters; after processing is completed, the control terminal issues a stop command, all drive components stop running, and the operator can remove the remaining roll material on the roll material installation mechanism 40.

[0055] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
