Description

Technical Field

[0001] This utility model relates to the technical field of traffic facility testing equipment, and in particular to a device for measuring the adhesion performance of reflective film. Background Technology

[0002] Reflective film, as the most widely used retroreflective material, is an important facility for ensuring traffic safety on highways. It plays an irreplaceable warning and guidance function during high-speed vehicle travel. To ensure that reflective film effectively fulfills its safety warning role, strict quality control must be maintained during installation, with the adhesion strength between the adhesive and the substrate being a core technical indicator for evaluating product performance.

[0003] Currently, the common method for testing the adhesion performance of reflective film is to attach the reflective film to a base plate, then attach a plumb bob to the end of the reflective film and let it hang naturally. After a period of time, the length of the reflective film peeled off the base plate is measured. However, during the process of reading the length data, the reflective film will continue to peel off due to the lack of support from the plumb bob, resulting in certain errors in the measured data. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a device for measuring the adhesion performance of reflective films, which solves the problem that the lack of support for the plumb bob during the measurement of the adhesion performance of reflective films affects the measurement results.

[0005] According to an embodiment of this utility model, a reflective film adhesion performance testing device includes: a base plate, a counterweight, a top plate, and a support plate. Two mounting columns are symmetrically arranged on the top of the base plate, and the top plate is located on top of the two mounting columns. A horizontal adhesive plate is provided at the bottom of the top plate for adhering the reflective film. A binding frame is provided on the counterweight for binding the ends of the reflective film. Vertical rods are also symmetrically arranged on the top of the base plate. Sliding seats are provided at both ends of the support plate. The two sliding seats are slidably connected to the two vertical rods in the vertical direction, and the support plate is located below the adhesive plate. Each sliding seat is provided with a locking component for locking it to the corresponding vertical rod.

[0006] Compared with the prior art, this utility model has the following beneficial effects: By setting an adhesive plate at the bottom of the top plate, when testing the adhesion of the reflective film, one end of the reflective film is pasted to the bottom of the adhesive plate, and a counterweight is tied to the other end of the reflective film. The counterweight causes the end of the reflective film to hang down naturally. After one end is left still for a period of time, the sliding seat is released by controlling the locking assembly, and then the support plate is pushed to move in the vertical direction, so that the support plate supports the counterweight. Then the locking assembly locks the sliding seat and the vertical rod, thereby keeping the support plate at this height position. Finally, the length of the reflective film detached from the adhesive plate is measured. By installing the support plate in the above manner, it is easy to adjust the height position of the support plate, so that the support plate can support the counterweight at different height positions, and prevent the reflective film from being peeled off further when measuring the length of the reflective film detached from the adhesive plate.

[0007] Furthermore, the sidewalls of the adhesive board are provided with scale lines for marking length.

[0008] Furthermore, each of the locking components includes: a mounting base and an elastic locking member. The mounting base is fixed to the side wall of the sliding base. The side wall of the vertical rod is provided with a plurality of slots evenly distributed in the vertical direction. The side wall of the mounting base that is in close contact with the sliding base is provided with a mounting groove. The elastic locking member is disposed in the mounting groove, and one end of the elastic locking member is used to be inserted into the corresponding slot.

[0009] Furthermore, each of the aforementioned elastic locking components includes: a locking pin, a spring, and a pull rod. The locking pin is slidably disposed in the mounting groove, and the spring is also disposed in the mounting groove. Under the elastic force of the spring, the locking pin is inserted into the slot. The pull rod is fixedly connected to one end of the locking pin away from the slot, and its other end extends out of the mounting seat. The pull rod is slidably connected to the mounting seat.

[0010] Furthermore, each of the aforementioned pull rods has a handle fixedly installed at the end opposite to the locking pin.

[0011] Furthermore, one end of the top plate is rotatably connected to the top of one of the mounting columns, and the other end of the top plate is supported on the top of another mounting column. The side wall of the mounting column rotatably connected to the end of the top plate is provided with a support column for supporting the top plate. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown in the figure, this utility model embodiment proposes a device for measuring the adhesion performance of reflective film, including: a base plate 1, a counterweight 6, a top plate 3, and a support plate 9. Two mounting columns 2 are symmetrically arranged on the top of the base plate 1. The top plate 3 is arranged on the top of the two mounting columns 2. A horizontal adhesive plate 4 is arranged at the bottom of the top plate 3. The adhesive plate 4 is used for adhering the reflective film 5. A binding frame 7 is arranged on the counterweight 6. The binding frame 7 is used for binding the end of the reflective film 5. Vertical rods 8 are also symmetrically arranged on the top of the base plate 1. Sliding seats 11 are arranged at both ends of the support plate 9. The two sliding seats 11 are slidably connected to the two vertical rods 8 in the vertical direction, and the support plate 9 is located below the adhesive plate 4. Each sliding seat 11 is provided with a locking component for locking it to the corresponding vertical rod 8.

[0017] By setting an adhesive plate 4 at the bottom of the top plate 3, when testing the adhesion of the reflective film 5, one end of the reflective film 5 is attached to the bottom of the adhesive plate 4, and a counterweight 6 is tied to the other end of the reflective film 5. The counterweight 6 causes the end of the reflective film 5 to hang down naturally. After one end is left to stand for a period of time, the sliding seat 11 is released by controlling the locking assembly, and then the support plate 9 is pushed to move in the vertical direction, so that the support plate 9 supports the counterweight 6. Then the locking assembly locks the sliding seat 11 to the vertical rod 8, thereby keeping the support plate 9 at this height position. Finally, the length of the reflective film 5 separated from the adhesive plate 4 is measured. By installing the support plate 9 in the above manner, it is easy to adjust the height position of the support plate 9, so that the support plate 9 can support the counterweight 6 at different height positions, and prevent the reflective film 5 from being peeled off when measuring the length of the reflective film 5 separated from the adhesive plate 4.

[0018] Furthermore, such as Figure 1 As shown, a scale line 10 for marking the length is provided on the side wall of the adhesive plate 4, so as to facilitate reading the length distance between the reflective film 5 and the adhesive plate 4.

[0019] like Figure 2As shown, each locking assembly includes: a mounting base 12 and an elastic locking member. The mounting base 12 is fixed to the side wall of the sliding base 11. The side wall of the vertical rod 8 is provided with a plurality of slots 13 evenly distributed in the vertical direction. The side wall of the mounting base 12 that is in close contact with the sliding base 11 is provided with a mounting groove. The elastic locking member is disposed in the mounting groove, and one end of the elastic locking member is used to insert into the corresponding slot 13. Each elastic locking member includes: a locking pin 14, a spring 15, and a pull rod 16. The locking pin 14 is slidably disposed in the mounting groove, and the spring 15 is also disposed in the mounting groove. Under the elastic force of the spring 15, the locking pin 14 is inserted into the slot 13. The pull rod 16 is fixedly connected to the end of the locking pin 14 away from the slot 13, and its other end extends out of the mounting base 12. The pull rod 16 is slidably connected to the mounting base 12.

[0020] When it is necessary to adjust the vertical movement of the support plate 9, the pull rod 16 is pulled to pull the locking pin 14 out of the corresponding slot 13. After the locking pin 14 is separated from the slot 13, the locking pin 14 no longer restricts the vertical movement of the sliding seat 11, and can then push the support plate 9 to move vertically. After the height position of the support plate 9 is adjusted, the support plate 9 is continuously pushed vertically upward so that the locking pin 14 can be aligned with the nearest slot 13. When the locking pin 14 is aligned with the slot 13, the locking pin 14 is reinserted into the slot 13 under the elastic force of the spring 15, thereby fixing the sliding seat 11. Specifically, a handle 17 can be provided at the end of the pull rod 16 to facilitate pulling the pull rod 16 through the handle 17.

[0021] As one embodiment, one end of the top plate 3 is rotatably connected to the top of one of the mounting columns 2, and the other end of the top plate 3 is supported on the top of another mounting column 2. The side wall of the mounting column 2, which is rotatably connected to the end of the top plate 3, is provided with a support column 18 for supporting the top plate 3. The top of the support column 18 and the bottom of the top plate 3 are on the same horizontal plane, so that the top plate can be rotated 180°, that is, the top plate 3 can be flipped over, so that the workers can easily paste the reflective film 5 onto the pasting plate 4.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
