Description

Technical Field

[0001] The utility model relates to the technical field of cold wrapping tape laminating, in particular to an alignment device for laminating the adhesive surface of a cold wrapping tape. Background Art

[0002] Cold wrapping tape refers to adhesive tape used for anti-corrosion wrapping. Cold wrapping tape is suitable for the anti-corrosion and repair of straight pipes, elbows, storage tanks, guides and other parts of pipelines in oil, natural gas, chemical industry, water supply and drainage. Cold wrapping tape is generally composed of a base film and an adhesive layer. The base film is a polyethylene film and the adhesive layer is butyl rubber, which has good mechanical strength and bonding and sealing properties. However, in actual processing, in order to prevent the adhesive layer from being damaged, aging and losing adhesion, or affecting the unwinding and use, a film is usually covered on the adhesive layer to protect the adhesive surface and facilitate the later unwinding and use.

[0003] There are many specifications of cold wrap tape. The factor that affects the coating mainly lies in the width of the tape surface. When the production specifications change, the film roller and the cold wrap tape need to be aligned to ensure that the cold wrap tape surface is completely coated. When aligning, the centering alignment method is basically the main method. Each time, it is necessary to calculate the width of the tape surface, calculate the position of the center line, and then adjust the film roller position to keep the centers of the two in the same vertical plane. This alignment method is more troublesome and requires higher operator skills. Utility Model Content

[0024] Embodiment 1:

[0025] In this embodiment, Figure 1 As shown, an alignment device for laminating the adhesive surface of a cold wrap tape comprises a conveying roller 1, on which passes a cut cold wrap tape 2 with the adhesive surface facing upward, a laminating alignment device 3 is arranged between the conveying rollers 1, and the laminating alignment device 3 comprises a vertical plate 4, a sliding column 5, a first screw rod 6, a side plate 7, a motor 8, a rotating shaft 9 and a positioner 10, the side plate 7 is slidably connected to the vertical plate 4 through the sliding column 5, the first screw rod 6 is mounted on the vertical plate 4 through a threaded structure, and one end of the first screw rod 6 is rotatably connected to the side plate 7, the rotating shaft 9 is rotatably mounted on the side plate 7, the motor 8 and the positioner 10 are both mounted on the side plate 7, the output end of the motor 8 is connected to the rotating shaft 9, the sensing end of the positioner 10 corresponds to the side of the cold wrap tape 2, and the positioner 10 is electrically connected to the motor 8 through a PLC controller.

[0026] First, select a film roll 21 of appropriate length and install it on the rotating shaft, then adjust the length of the positioner 10 protruding from the side plate 7, that is, control the width of the film roll 21 protruding from the side of the cold wrap 2, and then rotate the first screw 6 to press the positioner 10 against one side of the cold wrap 2 after trimming. At this time, the other side of the film roll 21 should also protrude outside the cold wrap 2 to ensure that the film layer completely covers the rubber surface, and finally start production. The alignment device uses the side of the cold wrap as a reference, and alignment is quick and simple.

[0027] Embodiment 2:

[0028] Based on the above embodiments, this embodiment Figure 2 and Figure 3 As shown, the positioner 10 includes a transverse plate 11, a baffle 12, a spring 13, a nut 14, a second screw 15, a rotating wheel 16 and an acceleration sensor 17. The transverse plate 11 is slidably mounted on the side plate 7, the baffle 12 is mounted on the bottom of the transverse plate 11, the second screw 15 is mounted on the side of the side plate 7 and passes through the transverse plate 11, the nut 14 is mounted on the second screw 15 through a threaded structure, the spring 13 is sleeved on the second screw 15, and the two ends of the spring 13 are respectively pressed against the baffle 12 and the nut 14, the rotating wheel 16 is rotatably mounted on the transverse plate 11, and the acceleration sensor 17 is mounted on the transverse plate 11 and corresponds to the rotating wheel 16.

[0029] Turn the nut 14 to control the position of the spring 13, thereby ensuring the distance between the rotating wheel 16 on the cross plate 11 and the side plate 7. When the continuously transmitted cold wrap tape 2 rotates with the rotating wheel 16, the acceleration sensor 17 is normal, ensuring normal lamination production, and the operator also knows that the alignment device is adjusted in place at this time.

[0030] Because the cold wrap tape 2 has been trimmed by the rotating wheel 16, it is generally neat. When the cold wrap tape conveying device (such as the conveying roller 1) works normally, the acceleration sensor 17 also works normally. Once the cold wrap tape conveying device does not work normally, the acceleration sensor 17 is stimulated to control the coating alignment device 3 and even the conveying roller 1 to stop working in time, check the cause, and prevent waste of raw materials.

[0031] Preferably, a washer 18 is provided between the nut 14 and the spring 13 .

[0032] When the nut 14 rotates, the washer 18 can prevent the spring 13 from interfering with it.

[0033] Preferably, the side surface of the rotating wheel 16 is provided in a groove 19 adapted to the side surface of the cold wrapping belt 2 .

[0034] The groove 19 is used to accommodate the side surface of the cold wrapping belt 2 to prevent the side surface of the cold wrapping belt 2 from deviating, thereby ensuring that the rotating wheel 16 rotates normally and stably.

[0035] Preferably, an indicator light 20 electrically connected to the PLC controller is provided on the side panel 7 .

[0036] The indicator light 20 is used to give employees an alarm or other indication so that they can understand the work situation in a timely manner.

[0037] Preferably, the rotating shaft 9 is mounted with two baffles 22 for clamping the film roll 21 by means of bolts.

[0038] The working process of the utility model is as follows: first select a film roll 21 of appropriate length and install it on the rotating shaft, then adjust the length of the positioner 10 protruding from the side plate 7, turn the nut 14, control the position of the spring 13, and then ensure the distance between the rotating wheel 16 on the cross plate 11 and the side plate 7. When the continuously transmitted cold wrap 2 rotates with the rotating wheel 16, the acceleration sensor 17 is normal, ensuring normal film coating production, and the operator also knows that the alignment device is adjusted in place at this time, that is, the width of the film roll 21 protruding from the side of the cold wrap 2 is controlled, and then the first screw is turned, 6 to press the positioner 10 against one side of the cold wrap 2 after trimming. At this time, the other side of the film roll 21 should also protrude outside the cold wrap 2 to ensure that the film layer completely covers the rubber surface. Finally, start the production. The alignment device takes the side of the cold wrap as a reference, and alignment is quick and simple.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
