Description

Technical Field

[0001] The utility model relates to the technical field of sticking adhesive strips on the top surface of a profile, in particular to a device for continuously sticking adhesive strips on a profile. Background Art

[0002] After a profile of a certain length is produced and formed, the process requires that a layer of adhesive strip 2 of a certain length be attached to the top surface of the profile 1. Figure 1 The figure shows a schematic diagram of the structure of the profile 1 with a rubber strip 2. The role of the rubber strip 2 is to prevent the profile 1 from hard contact with other parts when the finished product is assembled, thereby protecting the profile 1.

[0003] In the initial state, a continuous layer of release paper 3 is pasted on the adhesive layer of the adhesive strip 2. The release paper 3 protects the adhesive layer of the adhesive strip 2. The method for the workers in the workshop to paste the adhesive strip 2 with the release paper 3 on the profile 1 is as follows:

[0004] S1. The worker tears off the release paper 3 on the adhesive strip 2 in advance. After tearing it off, the worker can stick the adhesive layer of the adhesive strip 2 on the top surface of the profile 1, thereby sticking a first adhesive strip 2 on the first profile 1.

[0005] S2. The worker repeats step S1 multiple times to continuously stick a layer of adhesive strip 2 on multiple profiles 1.

[0006] However, although the film pasting method in the workshop can stick the adhesive strip 2 on the profile 1, it still has the following technical defects:

[0007] It is necessary to manually tear off the release paper 3 on the adhesive strip 2 before the adhesive layer of the adhesive strip 2 can be pasted on the profile 1. Both operations are performed manually, which undoubtedly increases the work intensity of the workers. At the same time, it takes a long time to paste a layer of adhesive strip 2 on each profile 1, thereby reducing the efficiency of adhesive strip pasting.

[0008] Therefore, there is an urgent need for a device that can greatly reduce the workload of workers and greatly improve the efficiency of adhesive strip application. Utility Model Content

[0042] An upper pressure wheel 19 and a lower pressure wheel 20 are rotatably mounted in the vertical plate 10 via the rotating shaft I17 and the rotating shaft II18 respectively. A left arcuate groove 21 and a right arcuate groove 22 are also provided in the vertical plate 10, which are respectively located on the left and right sides of the lower pressure wheel 20. A gap is formed between the upper pressure wheel 19 and the lower pressure wheel 20, and the height of the gap is equal to the total thickness of the adhesive strip 2 and the release paper 3. A pin 23 and a fixed column 24 are fixed on the back of the vertical plate 10, which are located above the rotating shaft I17. A straight plate 25 is rotatably mounted on the pin 23.

[0044] The automatic pasting mechanism 7 further comprises a mounting plate fixed on the top edge of the frame 9 , on the front end surface of which a reel 33 is rotatably mounted, and the reel 33 is wound with multiple turns of adhesive strip 2 pasted with release paper 3 .

[0045] The left connecting post 31 is slidably engaged with the left arcuate groove 21, and the right connecting post 27 is slidably engaged with the right arcuate groove 22. Two guide posts 35 are also fixedly provided on the front end surface of the vertical plate 10, and the two guide posts 35 are located above the upper pressing wheel 19.

[0046] The working process of this utility model is as follows:

[0047] S1. The worker first pulls the end portions of the adhesive strip 2 and the release paper 3 that are pasted together out from the roll 33, and then sequentially passes the end portions of the adhesive strip 2 and the release paper 3 through the area surrounded by the two guide posts 35, the area surrounded by the upper pressing wheel 19 and the lower pressing wheel 20, and the area surrounded by the lower pressing wheel 20 and the right pressing wheel 28. Then, the worker manually tears the end portions of the adhesive strip 2 and the release paper 3 apart, passes the torn end portion of the adhesive strip 2 through the square groove 16 in the fixing plate 15, and wraps it around the bottom of the roller 14, as shown in FIG. Figure 12 As shown, at this time, the adhesive strip 2 and the release paper 3 located between the lower pressing wheel 20 and the right pressing wheel 28 are pressed between the lower pressing wheel 20 and the right pressing wheel 28;

[0048] Then, the worker passes the leading end of the torn release paper 3 from bottom to top around the area surrounded by the lower pressing wheel 20 and the left pressing wheel 32, and then passes the leading end of the release paper 3 to the left around the top surface of the left pressing wheel 32. At this time, the release paper 3 between the lower pressing wheel 20 and the left pressing wheel 32 is pressed between the lower pressing wheel 20 and the left pressing wheel 32. Figure 12 As shown;

[0049] S2. The worker lifts the movable rod 12 upward along the length direction of the cylinder 11. The movable rod 12 compresses the spring A located in the cylinder 11. At the same time, the movable rod 12 drives the support plate 13 to move upward synchronously. The support plate 13 drives the roller 14 to move upward synchronously. Then, the worker takes out a profile 1 and embeds the left and right ends of the profile 1 into the two channel steels 34 respectively. Figure 13 As shown, the profile 1 is installed. Then, the worker releases the movable rod 12. Under the elastic restoring force of the spring A, the movable rod 12 moves away from the cylinder 11. The movable rod 12 drives the support plate 13, the roller 14 and the fixed plate 15 to move synchronously toward the profile 1. The roller 14 presses the head end of the rubber strip 2 onto the profile 1, thereby achieving the adhesion of the head end of the rubber strip 2 to the profile 1.

[0050] S3, the worker pushes the frame 9 of the automatic pasting mechanism 7 to the left along the horizontal guide rail 6 by hand, and the pushing direction is as follows Figure 13 As shown by the middle arrow, the automatic pasting mechanism 7 moves to the left along the length direction of the profile 1. During the movement, the roller 14 of the automatic pasting mechanism 7 gradually rolls the adhesive strip 2 onto the top surface of the profile 1. During the rolling process, the adhesive strip 2 and the release paper 3 are gradually released from the reel 33. Among them, the release paper 3 located between the right pressure wheel 28 and the lower pressure wheel 20 is released downward. The release paper 3 drives the lower pressure wheel 20 to rotate clockwise, and the lower pressure wheel 20 drives the left pressure wheel 32 to rotate counterclockwise. The left pressure wheel 32 peels the release paper 3 to the left side of the left pressure wheel 32, thereby achieving the adhesive strip 2 on the profile 1 while peeling the release paper 3 on the adhesive strip 2 to the left side of the left pressure wheel 32.

[0051] When the roller 14 moves to the left end of the profile 1, the worker cuts the adhesive strip 2, thereby pasting an adhesive strip 2 on the top surface of the first profile 1. The structure after pasting is as follows: Figure 1 As shown;

[0052] S4. The worker repeats steps S1 to S3 multiple times to continuously stick a layer of adhesive strip 2 on multiple profiles 1.

[0053] Among them, it can be seen from step S3 that the worker only needs to manually push the frame 9 of the automatic pasting mechanism 7 to the left along the horizontal guide rail 6, so that the roller 14 can gradually roll the adhesive strip 2 onto the top surface of the profile 1, and can tear the release paper 3 from the adhesive strip 2 through the cooperation of the left pressure wheel 32 and the lower pressure wheel 20, thereby completing the adhesive strip 2 on a profile 1. It can be seen that this device can achieve the goal of pasting the adhesive strip 2 on the profile 1 while peeling the release paper 3 on the adhesive strip 2 to the left side of the left pressure wheel 32, which not only greatly reduces the worker's workload, but also achieves the goal of pasting the adhesive strip 2 on the profile 1 in a short time, thereby greatly improving the efficiency of adhesive strip pasting.
