Description

Technical Field

[0001] This utility model relates to a beam adjustment device for a fabric splitting machine. Background Technology

[0002] Fabric slitting machines are crucial equipment in the textile, garment, and nonwoven fabric processing industries, used to cut rolls of fabric along their width to the required dimensions. In actual production, different fabric specifications have varying requirements for slitting position, tension control, and the spacing of the crossbeam supports (i.e., the opening distance). Especially when dealing with thick, high-tension, or easily deformable fabrics, if the crossbeams cannot adjust their height and spacing synchronously according to the fabric's condition, it can easily lead to fabric wrinkles, misalignment, or even fabric breakage, affecting slitting quality and yield.

[0003] Traditional fabric splitting machines typically employ a fixed beam installation structure, making it difficult to adjust once its position is set, thus hindering flexibility in handling fabrics of varying widths. While some improved models have introduced manual adjustment devices (such as bolt-locking sliders and lead screw handwheels), these suffer from low adjustment efficiency, poor precision, and high labor intensity, and are difficult to integrate with automated production lines. Furthermore, changing fabric rolls or switching process parameters often requires machine downtime, severely impacting production continuity and equipment utilization. Utility Model Content

[0004] The purpose of this invention is to provide a crossbeam adjustment device for a fabric splitting machine to solve the technical problems mentioned in the background section.

[0005] The technical solution to achieve the purpose of this utility model is: a crossbeam adjustment device for a fabric splitting machine, comprising: wall panels at both ends, a first crossbeam, a second crossbeam, a lifting assembly, a translation assembly, and an opening adjustment assembly. The first crossbeam and the second crossbeam are disposed between the two side wall panels. The lifting assembly is fixed on the wall panel. The translation assembly is disposed on the lifting assembly. The opening adjustment assembly is disposed on the lifting assembly. The opening adjustment assembly adjusts the opening distance between the first crossbeam and the second crossbeam.

[0006] Furthermore, the lifting assembly includes a lifting base and a lifting machine. The lifting base is fixed to the wall panel, and the translation component is located at the output end of the lifting machine. The lifting machine drives the translation component to move up and down.

[0007] Furthermore, the translation component includes a lifting bridge plate, a translation motor, a ball screw, and a translation slider. The lifting bridge plate is located at the output end of the elevator, the translation motor is fixed on the lifting bridge plate, the ball screw is located at the output end of the translation motor, and the translation slider is located on the ball screw. The translation motor drives the translation slider to move horizontally in a direction parallel to the wall panel, and the translation slider drives the opening adjustment component to move horizontally.

[0008] Furthermore, it also includes a lifting auxiliary component, which includes a lifting slide rail, a lifting slide base, and a lifting connecting block. The lifting slide rail is fixed to the wall panel, the lifting slide base is disposed on the lifting slide rail and slidably connected to the lifting slide rail along the length direction of the lifting slide rail, and the lifting connecting block is fixed on the lifting slide base and fixedly connected to the lifting bridge plate.

[0009] Furthermore, the opening adjustment assembly includes an opening motor, an opening lead screw, an opening lead screw bearing seat, a translation slide rail, a first slider, and a second slider. The opening motor and the translation slide rail are fixed to the lifting bridge plate. The opening lead screw is located at the output end of the opening motor. The opening lead screw bearing seat is located at the end of the opening lead screw and is slidably connected to the translation slide rail. The opening lead screw bearing seat is connected to the translation slider. The first slider and the second slider are located on the opening lead screw and are slidably connected to the translation slide rail. The first slider is connected to the first crossbeam, and the second slider is connected to the second crossbeam.

[0010] Furthermore, the opening screw is telescopic.

[0011] Furthermore, the opening screw is provided with two sections of thread, and the two sections of thread have opposite directions.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] (1) By integrating the lifting component, the translation component and the opening adjustment component, this utility model can simultaneously or independently complete the vertical lifting, horizontal translation and opening distance adjustment of the crossbeam, meet the process requirements of different widths, thicknesses and tensions of the fabric, and is especially suitable for flexible production scenarios with multiple varieties and small batches.

[0014] (2) The opening screw of this utility model is telescopic. When the translation motor drives the opening screw to extend or retract through the translation slider, it can drive the first crossbeam to move horizontally alone or simultaneously drive the first crossbeam and the second crossbeam.

[0015] (3) In the opening adjustment assembly of this utility model, the threads on both sides of the opening screw are opposite. With the opening motor drive, the first slider and the second slider move automatically and symmetrically towards or away from each other on the translation slide rail. No additional synchronization mechanism is required, which effectively avoids the synchronization error caused by the traditional dual motor or linkage structure, and ensures that the two crossbeams always remain parallel, thus improving the flattening quality of the fabric.

[0016] (4) The lifting auxiliary component of this utility model is provided with a lifting slide rail and a lifting connecting block, forming a double guide support structure with the lifting machine, which significantly enhances the rigidity and stability of the lifting bridge plate during vertical movement; the translation component adopts a ball screw and a translation slider in combination with the translation slide rail guide to achieve high precision and low friction horizontal movement, ensuring the repeatability of the beam position.

[0026] (Example 1)

[0027] See Figure 1 A crossbeam adjustment device for a fabric splitting machine includes: wall panels 1 on both sides, a first crossbeam 2, a second crossbeam 3, a lifting assembly 4, a translation assembly 5, and an opening adjustment assembly 6. The first crossbeam 2 and the second crossbeam 3 are positioned between the two wall panels 1. The lifting assembly 4 is fixed to the wall panel 1, the translation assembly 5 is mounted on the lifting assembly 4, and the opening adjustment assembly 6 is mounted on the lifting assembly 4. The opening adjustment assembly 6 adjusts the opening distance between the first crossbeam 2 and the second crossbeam 3. In this embodiment, two lifting assemblies 4, two translation assemblies 5, and two opening adjustment assemblies 6 are provided, respectively located at both ends of the crossbeam. Templates are mounted on both the first crossbeam 2 and the second crossbeam 3, and an adjustment mechanism for moving the templates is also provided.

[0028] The lifting assembly 4 includes a lifting base 41 and a lifting machine 42. The lifting base 41 is fixed on the wall panel 1, and the translation assembly 5 is set at the output end of the lifting machine 42. The lifting machine 42 drives the translation assembly 5 to rise and fall.

[0029] The translation component 5 includes a lifting bridge plate 51, a translation motor 52, a ball screw 53, and a translation slider 54. The lifting bridge plate 51 is located at the output end of the elevator 42, and can drive the lifting bridge plate 51 to rise and fall when the elevator 42 is running. As a preferred embodiment, two lifting seats 41 and elevators 42 are provided, which simultaneously drive the two ends of the lifting bridge plate 51 to move synchronously. At the same time, the elevators 42 at both ends of the crossbeam are connected by a coupling, so that the elevators 42 at both ends can run synchronously. Of course, they can also be controlled separately. The translation motor 52 is fixed on the lifting bridge plate 51, the ball screw 53 is located at the output end of the translation motor 52, and the translation slider 54 is located on the ball screw 53. The ball screw 53 is horizontally arranged parallel to the wall panel 1. The translation motor 52 drives the translation slider 54 to move horizontally on the ball screw 53, and the translation slider 54 drives the opening adjustment component 6 to move horizontally.

[0030] The system also includes a lifting auxiliary component 7, which comprises a lifting slide rail 71, a lifting slide base 72, and a lifting connecting block 73. The lifting slide rail 71 is fixed to the wall panel 1. The lifting slide base 72 is disposed on the lifting slide rail 71 and slidably connected to the lifting slide rail 71 along its length. The lifting connecting block 73 is fixed to the lifting slide base 72 and is fixedly connected to the lifting bridge plate 51. The lifting auxiliary component 7, with its lifting slide rail 71 and lifting connecting block 73, forms a double-guide support structure with the elevator 42, significantly enhancing the rigidity and stability of the lifting bridge plate 51 during vertical movement.

[0031] The opening adjustment assembly 6 includes an opening motor 61, an opening lead screw 62, an opening lead screw bearing seat 63, a translational slide rail 64, a first slider 65, and a second slider 66. The opening motor 61 and the translational slide rail 64 are fixed on the lifting bridge plate 51. The opening lead screw 62 is located at the output end of the opening motor 61. The opening lead screw bearing seat 63 is located at the end of the opening lead screw 62 and is slidably connected to the translational slide rail 64. The opening lead screw bearing seat 63 is connected to the translational slider 54. In this embodiment, the opening lead screw 62 adopts a telescopic structure. Telescopic opening lead screw 62 is a relatively mature technology in the industry and will not be described in detail here. The first slider 65 and the second slider 66 are located on the opening lead screw 62 and are slidably connected to the translational slide rail 64. The first slider 65 is connected to the first crossbeam 2, and the second slider 66 is connected to the second crossbeam 3. When the translation motor 52 drives the translation slider 54 to move, the translation slider 54 drives the opening screw bearing seat 63 to move, thereby causing the opening screw 62 to extend and retract. The opening screw 62 has two threaded sections, which respectively engage with the first slider 65 and the second slider 66. Different relative positions of the threaded section and the extension section of the opening screw 62 can achieve different movement modes. In one embodiment, when the extension section is located between the two threaded sections, the extension and retraction of the opening screw 62 causes the first slider 65 to move axially along the opening screw 62, allowing for independent adjustment of the position of the first crossbeam 2. In another embodiment, when the extension section is located between the opening motor 61 and the threaded section, the extension and retraction of the opening screw 62 can simultaneously cause the first slider 65 and the second slider 66 to move axially along the opening screw 62, thus causing the first crossbeam 2 and the second crossbeam 3 to move simultaneously.

[0032] In this embodiment, the opening screw 62 is provided with two sections of thread, and the two sections of thread are in opposite directions. With the drive of the opening motor 61, the first slider 65 and the second slider 66 automatically move symmetrically towards or away from each other on the translation slide rail 64. No additional synchronization mechanism is required, which effectively avoids the synchronization error caused by the traditional dual motor or linkage structure, and ensures that the two crossbeams always remain parallel, thereby improving the flattening quality of the fabric.

[0033] This utility model integrates a lifting component 4, a translation component 5, and an opening adjustment component 6, which can simultaneously or independently complete the vertical lifting, horizontal translation, and opening distance adjustment of the crossbeam, meeting the process requirements of fabrics with different widths, thicknesses, and tensions, and is especially suitable for flexible production scenarios with multiple varieties and small batches.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
