Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive production technology, and in particular to a double-sided adhesive coating device. Background Technology

[0002] Double-sided adhesive is a special type of adhesive whose main component is pressure-sensitive adhesive, usually made of acrylic polymers or rubber polymers. In the production of double-sided adhesive, the adhesive needs to be applied to a non-sticky sticker.

[0003] When applying double-sided adhesive, the melted double-sided adhesive and non-adhesive paper are placed between two rollers. The opposing rotation of the two rollers adheres the double-sided adhesive and non-adhesive paper together and transfers them, thus evenly applying the double-sided adhesive to the surface of the non-adhesive paper. Then, the paper is cooled and wound up.

[0004] When producing different double-sided adhesives, it is necessary to adjust the gap between the rollers. The traditional method is to adjust the gap by using screws on both sides of the rollers. This requires stopping the machine for adjustment, which affects production efficiency. Therefore, this application proposes a double-sided adhesive coating device. Utility Model Content

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-3 As shown, this utility model proposes a double-sided adhesive coating device, including a frame 1. A support sleeve 5 is fixedly connected inside the frame 1. A worm gear 4 is rotatably connected inside the support sleeve 5, ensuring the stability of the worm gear 4's rotation. A worm wheel 3 is rotatably connected outside the worm gear 4, and the worm wheel 3 is slidably connected inside the frame 1. The worm gear 4 can drive the worm wheel 3 to move outside the worm gear 4. A connecting rod 17 is rotatably connected inside the worm wheel 3. There are two connecting rods 17 arranged symmetrically. A lower pressure roller 2 is fixedly connected to one side of the connecting rod 17. A support roller 6 is arranged below the lower pressure roller 2. The mutual rotation of the lower pressure roller 2 and the support roller 6 can extrude the double-sided adhesive and non-adhesive paper. The worm gear 4 is further... A drive assembly is provided at one end of the support sleeve 5. The drive assembly includes a drive block 7, which can fix the wrench outside and rotate it, thereby driving the worm gear 4 to rotate. A rotating sleeve 8 is slidably connected to the outside of the drive block 7. A sliding block 9 is fixedly connected to the end of the rotating sleeve 8 away from the drive block 7. A drive sleeve 10 is fitted outside the sliding block 9. The sliding block 9 can slide inside the drive sleeve 10, thereby allowing the rotating sleeve 8 to disengage from the outside of the drive block 7. In this way, the wrench can be used to drive the drive block 7 and the worm gear 4 to rotate. A motor 14 is fixedly connected to the side of the drive sleeve 10 away from the sliding block 9. During normal use, the motor 14 can drive the drive sleeve 10, the sliding block 9, and the rotating sleeve 8 to drive the drive block 7 and the worm gear 4 to rotate.

[0022] also Figure 1 and Figure 3As shown, the rotating sleeve 8 is slidably connected inside the frame 1. The position of the rotating sleeve 8 can be adjusted inside the frame 1. The motor 14 is fixedly connected to a fixing frame 15, which is arranged in an "n" shape. The fixing frame 15 can stably support the motor 14, ensuring that the motor 14 can stably serve as a drive source. The fixing frame 15 is fixedly connected to the top of the frame 1. The top of the frame 1 is slidably connected to an insert plate 11. When the rotating sleeve 8 is pulled out from inside the frame 1, the insert plate 11 can be inserted under the rotating sleeve 8 to prevent the rotating sleeve 8 from affecting the manual operation of the drive block 7 and the worm gear 4. The insert plate 11 is slidably connected to a positioning frame 12, which is fixedly connected to the top of the frame 1. The positioning frame 12 can limit the sliding direction of the insert plate 11. The side of the insert plate 11 away from the frame 1 is fixedly connected to a limit block 13. There are two limit blocks 13 arranged symmetrically. The limit blocks 13 can limit the insert plate 11 and prevent the insert plate 11 from slipping out of the positioning frame 12.

[0023] in addition Figure 4 and Figure 5 As shown, a bearing 18 is rotatably connected to the connecting rod 17, which is away from the inside of the worm gear 3. The bearing 18 ensures the stable rotation of the connecting rod 17. A protective sleeve 19 is rotatably connected to the outside of the bearing 18 to protect the bearing 18 and prevent dust particles from entering the bearing 18. A lifting assembly is provided outside the protective sleeve 19. The lifting assembly includes a telescopic rod 20, which is fixedly connected to the outside of the protective sleeve 19. A sleeve 21 is slidably connected to the outside of the telescopic rod 20, away from the sliding block 9. The sleeve 21 can restrict the sliding and lifting position of the protective sleeve 19 to avoid unstable lifting of the lower pressure roller 2. The sleeve 21 is fixedly connected inside the frame 1. A drive plate 16 is fixedly connected to both ends of the support roller 6. The drive plate 16 can drive the support roller 6 to rotate, thereby cooperating with the lower pressure roller 2 to coat the double-sided adhesive on the non-stick side. The drive plate 16 is fixedly connected inside the frame 1.

[0024] In this embodiment, the opposing rotation of the pressure roller 2 and the support roller 6 can coat the double-sided adhesive and non-stick paper. It is necessary to increase the gap between the pressure roller 2 and the support roller 6. At this time, the motor 14 can be started. The motor 14 will drive the drive sleeve 10, the sliding block 9 and the rotating sleeve 8 to rotate under the support of the fixed frame 15. This will cause the rotating sleeve 8 to drive the drive block 7 and the worm gear 4 to rotate. In this way, the worm gear 3 will move outside the worm gear 4 and inside the frame 1. This allows the distance between the pressure roller 2 and the support roller 6 to be adjusted, so that double-sided adhesives of different materials can be coated.

[0025] When the lower pressure roller 2 is driven to rotate by the yarn tube paper driven by the support roller 6, the lower pressure roller 2 relies on the connecting rod 17 and the bearing 18 to ensure smooth rotation. The protective sleeve 19 can also prevent dust, particles or double-sided adhesive from entering between the rotating sleeve 8 and the connecting rod 17 during the rotation of the bearing 18, causing wear or resistance. The telescopic rod 20 outside the protective sleeve 19 will slide inside the sleeve 21, thereby cooperating with the worm gear 3 to make corresponding height changes, improving the stability of the lower pressure roller 2 during adjustment.

[0026] When the motor 14 malfunctions, the sliding block 9 can slide along the inside of the drive sleeve 10, thereby moving the rotating sleeve 8 upward and disengaging it from the drive block 7. Then, the limiting block 13 drives the insert plate 11 to slide along the inside of the positioning frame 12 to below the rotating sleeve 8, thus preventing the rotating sleeve 8 from falling back. Once the insert plate 11 has properly positioned the rotating sleeve 8, the drive block 7 can be rotated using a wrench, thereby causing the drive block 7 to rotate the worm gear 4, which in turn adjusts the position of the lower pressure roller 2 and the worm gear 3.

[0027] After adjustment, the drive plate 16 can drive the support roller 6 to rotate. In this way, the double-sided adhesive and non-stick paper will be transported along the upper part of the support roller 6. The non-stick material of the pressure roller 2 can prevent the double-sided adhesive from sticking to the surface of the pressure roller 2. The gap between the pressure roller 2 and the support roller 6 can allow the double-sided adhesive and non-stick paper to be squeezed through, thereby performing the coating process.

[0028] It should be noted that this device uses the worm gear 4 to drive the worm wheel 3 to rotate, which can control the distance between the lower pressure roller 2 and the support roller 6. The sliding mechanism of the rotating sleeve 8 and the drive block 7 allows the drive block 7 and the worm gear 4 to be manually adjusted even if the motor 14 fails, thereby controlling the height adjustment of the worm wheel 3 and the lower pressure roller 2. This solves the problem that adjusting the distance between the lower pressure roller 2 and the support roller 6 previously required replacing the lower pressure roller 2, which led to downtime and reduced production efficiency. This improves the convenience of adjusting the distance between the lower pressure roller 2 and the support roller 6.

[0029] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
