Description

Technical Field

[0001] This utility model belongs to the field of reflective fabric processing technology, specifically relating to a high-precision edge trimming mechanism for reflective fabric that is easy to automatically adjust. Background Technology

[0002] Reflective fabric, also known as reflective cloth or retroreflective fabric, is made by applying glass microbeads to the fabric. It utilizes the optical principle that light is refracted and reflected within the glass microbeads and then returns to its original direction. Even if the reflected light returns to the direction of the light source in the direction of the incident light, this fabric is a safety-functional fabric. During the processing of reflective fabric, before rolling it up, the processing personnel need to trim the edges of the reflective fabric.

[0003] For example, in the Chinese utility model patent with announcement number CN214882555U, entitled "An Automatic Edge Trimming Device for Reflective Fabric", it specifically includes a worktable. Both ends of the top of the worktable are fixedly connected to baffles. A first motor is provided on one side of the top of the worktable. A rotating rod is provided at the output end of the first motor. The rotating rod passes through one of the baffles. Although the height of the edge trimming mechanism can be adjusted according to different sizes of the weaving machine using the above-mentioned prior art, the width of the reflective fabric is inconsistent for different batches, and the cutting width is also inconsistent. Therefore, there is a need for a high-precision edge trimming mechanism for reflective fabric that is easy to automatically adjust. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision edge-cutting mechanism for reflective fabric that is simple in structure, reasonably designed, and easy to automatically adjust in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A high-precision edge trimming mechanism for reflective fabric that is easy to automatically adjust includes a base. The base has two first sliding grooves along the edge of the reflective fabric. A first sliding plate is slidably arranged on the inner side of each of the two first sliding grooves. A through groove is vertically opened on each of the two first sliding plates. Support rods are fixedly arranged on the upper sides of the four corners of the base. A top plate is fixedly arranged on the upper ends of the multiple support rods. Two edge trimming components are arranged on the top plate, which respectively cooperate with the first sliding plates. An adjustment mechanism is arranged on the upper side of the top plate to drive the two edge trimming components to move.

[0007] As a further optimization of this utility model, the adjustment mechanism includes a second slide groove opened on the upper side of the top plate, a second slide plate slidably disposed on the inner side of the second slide groove, a first electric telescopic rod for driving the second slide plate to slide fixedly disposed on the upper side of the top plate, suspension rods fixedly disposed at both ends of the lower side of the second slide plate, a lifting plate slidably disposed on the two suspension rods, a second electric telescopic rod for driving the lifting plate to move up and down fixedly disposed on the upper side of the second slide plate, and the trimming assembly slidably disposed on the lifting plate.

[0008] As a further optimization of this utility model, the trimming assembly includes a limiting groove formed on the lifting plate, a lead screw rotatably arranged inside the limiting groove, a threaded sleeve threaded on the lead screw and slidably connected to the limiting groove, a trimming motor fixedly arranged on the lower side of the threaded sleeve, a trimming knife fixedly arranged at the output end of the trimming motor, a driving mechanism for driving the lead screw to rotate is arranged at one end of the lifting plate, and a pressing mechanism is arranged on both sides of the lifting plate.

[0009] As a further optimization of this utility model, the driving mechanism includes a servo motor fixedly mounted on the upper side of the lifting plate, a drive gear fixedly mounted on the output end of the servo motor, and a driven gear fixedly mounted on the lead screw meshing on one side of the drive gear.

[0010] As a further optimization of this utility model, the pressing mechanism includes a sliding rod that slides through the lifting plate, a pressing spring connected to the lifting plate is fixedly provided at the upper end of the sliding rod, and a pressure plate located below the lifting plate is fixedly provided at the lower end of the sliding rod.

[0011] As a further optimization of this utility model, a connecting rod is fixedly provided on one side of the second skateboard and fixedly connected to one side of the first skateboard. The connecting rod adopts a "U" shaped structure.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a first electric telescopic rod to drive a second sliding plate to move along the width direction of the reflective fabric. This allows the suspension rod on the lower side of the second sliding plate and the lifting plate on the suspension rod to move together, causing the cutting blade on the lifting plate to move along the width direction of the reflective fabric. This adjusts the distance between the cutting blade and the edge of the reflective fabric in the width direction, allowing for the cutting of different batches of reflective fabric. Furthermore, the second electric telescopic rod drives the lifting plate to descend, which in turn drives the pressure plates on both sides of the lifting plate to descend. This causes the pressure plates to press the two sides of the cut part of the reflective fabric tightly, preventing the reflective fabric from shifting during subsequent cutting and affecting the cutting quality.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a high-precision edge-cutting mechanism for reflective fabric that is easy to automatically adjust includes a base 1. Two first sliding grooves 4 are formed on the base 1 along the edge of the reflective fabric. First sliding plates 5 are slidably mounted on the inner sides of both first sliding grooves 4. The first sliding plates 5 slide horizontally inside the first sliding grooves 4, providing a support surface for edge cutting of the reflective fabric. Vertical through grooves 6 are formed on the two first sliding plates 5, facilitating the raising of the cutting channel for the reflective fabric and the discharge of cutting waste. Support rods 2 are fixedly mounted on the upper sides of the four corners of the base 1. A top plate 3 is fixedly mounted on the upper ends of the multiple support rods 2. The top plate 3 is located above the base 1 and has two supports respectively connected to the first sliding plates 5. The matching trimming assembly 14 has two second sliding grooves 7 on the front and rear of the top plate 3. The two second sliding grooves 7 are located directly above the two first sliding grooves 4. A second sliding plate 8 is slidably arranged inside the second sliding groove 7. The second sliding plate 8 is horizontally slidable. A connecting rod 15 is fixedly arranged on one side of the second sliding plate 8 and fixedly connected to one side of the first sliding plate 5. The connecting rod 15 adopts a "U" shape structure. The first sliding plate 5 and the second sliding plate 8 can be connected together through the connecting rod 15, so that the first sliding plate 5 and the second sliding plate 8 move synchronously, so that the first sliding plate 5 is always directly below the second sliding plate 8. A first electric telescopic rod 9 is fixedly arranged on the upper side of the top plate 3 to drive the second sliding plate 8 to slide. The lower ends of the second sliding plate 8 are respectively A suspension rod 11 is fixedly installed, and a lifting plate 12 is slidably installed on both suspension rods 11. A second electric telescopic rod 10 for driving the lifting plate 12 to move up and down is fixedly installed on the upper side of the second sliding plate 8. An edge trimming assembly 14 is slidably installed on the lifting plate 12. The edge trimming assembly 14 includes a limiting groove 1404 opened on the lifting plate 12. A lead screw 1405 is rotatably installed inside the limiting groove 1404. A threaded sleeve 1403 that is slidably connected to the limiting groove 1404 is threaded on the lead screw 1405. An edge trimming motor 1401 is fixedly installed on the lower side of the threaded sleeve 1403. An edge trimming knife 1402 is fixedly installed at the output end of the edge trimming motor 1401. A servo motor 140 is fixedly installed on the upper side of the lifting plate 12. 8. A drive gear 1407 is fixedly installed at the output end of the servo motor 1408. A driven gear 1406 fixedly sleeved on the lead screw 1405 meshes with one side of the drive gear 1407. During trimming, the servo motor 1408 drives the drive gear 1407 to rotate, which in turn drives the driven gear 1406 to rotate, causing the lead screw 1405 to rotate inside the limiting groove 1404. This causes the threaded sleeve 1403 to slide inside the limiting groove 1404, which in turn drives the trimming blade 1402 under the threaded sleeve 1403 to move along the edge of the reflective fabric. During the movement, the trimming motor 1401 drives the trimming blade 1402 to rotate, which allows the edge of the reflective fabric to be trimmed.

[0022] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, pressing mechanisms 13 are provided on both sides of the lifting plate 12. The pressing mechanism 13 includes a slide rod 1301 that slides through the lifting plate 12. A pressing spring 1302 connected to the lifting plate 12 is fixedly provided at the upper end of the slide rod 1301. A pressure plate 1303 located below the lifting plate 12 is fixedly provided at the lower end of the slide rod 1301. When the pressure plate 1303 is in its initial position, its bottom surface is lower than the bottom edge of the cutting blade 1402. In use, the lifting plate 12 is lowered by the second electric telescopic rod 10. This causes the lifting plate 12 to lower the pressure plates 1303 on both sides, which in turn press the two sides of the reflective fabric cutting area tightly. During the pressing process, the sliding rod 1301 drives the pressure spring 1302 to stretch. The reaction force of the pressure spring 1302 causes the sliding rod 1301 to press down, which in turn causes the pressure plate 1303 at the lower end of the sliding rod 1301 to press tightly onto the reflective fabric, preventing the reflective fabric from shifting during the subsequent edge cutting process and affecting the edge cutting quality.

[0023] It should be noted that this high-precision edge-cutting mechanism for reflective fabric, which is easy to adjust automatically, works as follows: When the reflective fabric passes through the upper side of the base 1, the first electric telescopic rod 9 drives the second slide plate 8 to move along the width direction of the reflective fabric. This causes the suspension rod 11 on the lower side of the second slide plate 8 and the lifting plate 12 on the suspension rod 11 to move together. This causes the edge-cutting blade 1402 on the lifting plate 12 to move along the width direction of the reflective fabric, thereby adjusting the distance between the edge-cutting blade 1402 and the edge of the reflective fabric in the width direction. This allows for edge cutting of different batches of reflective fabric. Then, the second electric telescopic rod 10 drives the lifting plate 12 to descend, causing the lifting plate 12 to drive the pressure plates 1303 on both sides to descend. This causes the pressure plates 1303 to press the two sides of the cut part of the reflective fabric tightly. During the pressing process, the sliding rod 1301 drives the compression spring 1302 to stretch. The reaction force of the compression spring 1302 causes the sliding rod 1301 to press down, thereby causing the pressure plate 1303 at the lower end of the sliding rod 1301 to press tightly onto the reflective cloth. Then, the servo motor 1408 drives the drive gear 1407 to rotate, which in turn drives the driven gear 1406 to rotate, causing the lead screw 1405 to rotate inside the limiting groove 1404. This causes the threaded sleeve 1403 to slide inside the limiting groove 1404, which in turn drives the trimming knife 1402 on the lower side of the threaded sleeve 1403 to move along the edge of the reflective cloth. During the movement, the trimming motor 1401 drives the trimming knife 1402 to rotate, which allows the edge of the reflective cloth to be trimmed.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
