Description

Technical Field

[0001] This utility model relates to the field of adhesive backing processing technology, and in particular to a die-cutting adhesive backing device. Background Technology

[0002] Die-cut adhesive backing equipment is an automated device that uses precision die-cutting technology to cut adhesive backing materials into the designed shape and attach them to the surface of the target substrate. It is widely used in component bonding and functional packaging in the fields of electronics, packaging, and automobiles.

[0003] Currently, existing die-cutting and adhesive-backing equipment typically only has basic die-cutting and adhesive-backing functions. Although it can complete the processing of conventional roll materials, it cannot be adjusted and limited according to roll materials of different widths. This results in poor adaptability when dealing with roll materials of different specifications, frequent roll material deviation during processing, which in turn leads to increased defect rate, increased production costs, reduced production efficiency, and difficulty in ensuring processing stability and product quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to adjust and limit the width of rolls, resulting in poor adaptability to rolls of different specifications and frequent roll offset during processing. This invention proposes a die-cutting adhesive backing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A die-cutting adhesive backing device, comprising: The machine body has a bracket I fixedly installed on the rear side. The top of the bracket I has two support columns fixedly installed symmetrically. The top of the two support columns is fixedly installed with the same bracket II. Mounting frames can be slidably installed in the sliding grooves of the bracket I and the bracket II. Rollers are rotatably installed on one side of the multiple mounting frames. Each of the multiple rollers is equipped with a limiting mechanism, which is used to adjust according to the width of different rolls. The machine body is equipped with an exhaust assembly, which is used to remove air bubbles during the process of foaming and adhesive backing.

[0006] In one possible design, the limiting mechanism includes a bidirectional lead screw rotatably disposed inside the roller, with baffles sleeved on the outer sides of both ends of the roller, and movable frames disposed inside both ends of the roller. The bottoms of the two movable frames pass through the roller and are fixedly connected to the two baffles respectively. The two movable frames are threadedly connected to different threaded ends on the outer sides of the bidirectional lead screw, and a rectangular adjusting block is fixedly disposed at the outer end of the bidirectional lead screw.

[0007] In one possible design, the exhaust assembly includes an inverted U-shaped frame fixedly mounted on the top of the machine body. Sliders are slidably mounted on both sides of the inverted U-shaped frame. A common roller is rotatably mounted on the side of the two sliders that are close to each other. Support rods are threaded through both sides of the top of the inverted U-shaped frame. The bottom ends of the two support rods are fixedly connected to the tops of the two slides, respectively. A common connecting plate is fixedly mounted on the top of the two support rods. A screw is threaded through the top of the connecting plate. The bottom end of the screw is rotatably connected to the top of the connecting plate. A handwheel is fixedly mounted on the top of the screw.

[0008] In one possible design, one side of each of the mounting brackets is threaded with a knob bolt.

[0009] In one possible design, a motor is fixedly mounted on one side of one of the mounting brackets on the bracket I, and the output shaft of the motor is fixedly connected to the roller on the mounting bracket.

[0010] In one possible design, a guide frame is adjustablely fixed to the side of the machine body away from the motor by bolts.

[0011] In this application, when starting to use the machine, first connect the entire machine to the power supply, then select an appropriate number of mounting brackets, and then slide the mounting brackets with the rollers and motors into the grooves of bracket I and bracket II respectively. After the mounting brackets are slid into the appropriate positions, rotate the threaded knob bolts on one side of the mounting brackets so that the rod end of the knob bolts abuts against one side of bracket I or bracket II, thereby firmly fixing the position of the mounting brackets and ensuring that the rollers remain stable during processing. For the guide brackets on the side of the machine away from the motor, since they are adjustable and fixed by bolts, the operator can loosen the bolts and adjust the position and angle of the guide brackets according to the direction of the roll material and processing requirements, so that they can accurately guide the roll material. After adjustment, tighten the bolts to fix the guide brackets. Subsequently, the limiting mechanism on the roll is adjusted according to the different widths of the roll material. The operator holds or drives the rectangular adjusting block to rotate using a tool. Since the rectangular adjusting block is fixed to the outer end of the bidirectional lead screw, rotating the rectangular adjusting block will drive the bidirectional lead screw to rotate together. The moving frames inside both ends of the roll are respectively threaded to the different threaded ends outside the two ends of the bidirectional lead screw. When the bidirectional lead screw rotates, the two moving frames will move in opposite or opposite directions along the inside of the roll. Since the bottom of the moving frame passes through the roll and is fixedly connected to the baffle, the movement of the moving frame will drive the baffle to move synchronously outside both ends of the roll, thereby adjusting the two baffles to the appropriate position according to the width of the roll material, realizing the limiting of the roll material and preventing it from deviating during processing. Next, the exhaust assembly is adjusted. The operator first turns the handwheel, which drives the screw to rotate. When the screw rotates, the connecting plate moves up and down along the screw, which in turn drives the slide to slide up and down on both sides of the inverted U-shaped frame through the support rod. The movement of the slide will drive the roller to move up and down. According to the thickness of the roll material and the adhesive backing, the roller is adjusted to a suitable height so that it can effectively expel air bubbles. After completing the above preparations and parameter adjustments, first pull the adhesive-backed roll material onto the roller connected to the motor output shaft. Then start the motor. After the motor starts, it drives the connected roller to rotate and begin winding the adhesive-backed roll material. The remaining rollers automatically release the foam and adhesive paper under the pull of the roll material when the motor is working. During the release process, the roll material is guided by the guide frame and accurately enters the processing area (die-cutting area). During the adhesive application of the foam and adhesive paper, the roller of the venting component crushes the roll material to remove air bubbles and ensure the quality of the adhesive application. As the motor continues to run, the entire die-cutting and adhesive application operation proceeds in an orderly manner until the production task is completed.

[0012] This utility model has the following beneficial effects: In this invention, a limiting mechanism is used to rotate a rectangular adjusting block, which drives a bidirectional lead screw to rotate. This causes a movable frame, threaded to both ends of the bidirectional lead screw, to move the baffles synchronously at both ends of the roll. The position of the two baffles can be flexibly adjusted according to different widths of roll material. This not only achieves precise limiting of the roll material and effectively prevents the roll material from shifting during processing, but also improves the equipment's adaptability to roll materials of different specifications, reduces the defect rate caused by roll material shifting, lowers production costs, improves production efficiency, and ensures processing stability and product quality.

[0013] In this invention, the venting assembly allows the operator to rotate the screw by turning the handwheel, which in turn causes the connecting plate to move up and down via the support rod, moving the slide and the roller up and down. This allows for flexible adjustment of the roller height based on the thickness of the roll material and the adhesive backing. Simultaneously, during the adhesive bonding process between the foam and the adhesive paper, the roller effectively crushes the roll material, fully expelling air bubbles. This effectively avoids problems such as weak adhesive bonding and uneven surface caused by residual air bubbles, greatly improving the quality of the adhesive backing and ensuring the overall quality of the product.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment Reference Figure 1-4 An apparatus comprising: The main body 1 serves as the supporting structure for the entire equipment. A bracket I2 is securely fixed to its rear side. Two support columns 3 are symmetrically fixed to the top of the bracket I2, supporting the bracket II4 above. This creates a stable spatial structure between the bracket I2 and the bracket II4. Mounting frames 5 can be slidably installed in the grooves of both the bracket I2 and the bracket II4. The number of mounting frames 5 can be flexibly increased or decreased according to actual production needs. A roller 6 is rotatably installed on one side of each mounting frame 5. The roller 6 is used to place foam, adhesive paper, and roll up the adhesive-backed roll material.

[0018] To achieve precise positioning of rolls of different widths, a limiting mechanism is installed on multiple rolls 6. This includes a bidirectional lead screw 7 rotatably mounted inside the roll 6, baffles 9 fitted on the outer ends of both ends of the roll 6, and movable frames 8 installed inside both ends of the roll 6. The bottoms of the two movable frames 8 pass through the roll 6 and are fixedly connected to the two baffles 9 respectively. The two movable frames 8 are threadedly connected to different threaded ends on the outer ends of the bidirectional lead screw 7. A rectangular adjusting block 10 is fixedly mounted on the outer end of the bidirectional lead screw 7. When the position of the baffles 9 needs to be adjusted, the operator only needs to hold or use a tool to rotate the rectangular adjusting block 10, and the bidirectional lead screw 7 will rotate accordingly. Due to the threaded connection between the two movable frames 8 and the bidirectional lead screw 7, the two movable frames 8 will move in opposite or opposite directions along the inside of the roll 6, thereby driving the baffles 9 to move synchronously on the outer ends of the roll 6. This adapts to rolls of different widths and prevents the rolls from shifting during processing.

[0019] During the adhesive bonding process between foam and adhesive paper, air bubbles can occur, affecting the adhesive quality. Therefore, an venting assembly is installed on the machine body 1. The inverted U-shaped frame 13 of the venting assembly is fixedly mounted on the top of the machine body 1, providing stable support for the entire venting structure. Slide carriages 14 are slidably mounted on both sides of the inverted U-shaped frame 13. A common roller 15 is rotatably mounted on the side of the two slide carriages 14 that are close together. The roller 15 is used to crush the roll material to remove air bubbles. Support rods 16 are threaded through the top of the inverted U-shaped frame 13 on both sides. The bottom ends of the two support rods 16 are respectively connected to the top of the two slide carriages 14. The two support rods 16 are fixedly connected with the same connecting plate 17 at their top ends. The top of the connecting plate 17 is threadedly connected to a screw 18. The bottom end of the screw 18 is rotatably connected to the top of the connecting plate 17. A handwheel 19 is fixedly installed at the top of the screw 18. When the operator turns the handwheel 19, the screw 18 will rotate, and the connecting plate 17 will move up and down along the screw 18. This will drive the slide 14 to slide up and down on both sides of the inverted U-shaped frame 13 through the support rods 16, so that the roller 15 can be moved to a suitable height to meet the air release requirements of rolls of different thicknesses.

[0020] A motor 11 is fixedly installed on one side of one of the mounting brackets 5 on the bracket I2. The output shaft of the motor 11 is fixedly connected to the roller 6 on the mounting bracket 5. The roller 6 on the mounting bracket 5 where the motor 11 is installed is used to wind up the adhesive-backed roll material. The other rollers 6 automatically release the foam and adhesive paper by pulling the roll material when the motor 11 is working.

[0021] This application can be used in the field of die-cutting adhesive backing device technology, and can also be used in other fields applicable to this application.

[0022] In another embodiment Reference Figure 1-2 A die-cutting adhesive backing device is applied to the field of die-cutting adhesive backing device technology. Multiple mounting brackets 5 have threaded connections of knob bolts 12 on one side. When the mounting bracket 5 is slid into the bracket I2 or bracket II4, the knob bolts 12 are rotated so that the rod end of the knob bolt 12 abuts against one side of the bracket I2 or bracket II4, thereby firmly fixing the position of the mounting bracket 5 and ensuring the stability of the roller 6 during the processing.

[0023] A guide frame 20 is fixedly installed on the side of the machine body 1 away from the motor 11 by bolts. The operator can loosen the bolts and flexibly adjust the angle of the guide frame 20 according to the direction of the roll material and the processing requirements, so that it can accurately guide the roll material into the processing area. After adjustment, tighten the bolts to fix the guide frame 20.

[0024] However, as is well known to those skilled in the art, the working principle and wiring method of motor 11 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
