Description

Technical Field

[0001] The utility model relates to the technical field of rubber film break detection, in particular to a device for detecting chloroprene rubber film break. Background Art

[0002] Neoprene is a synthetic rubber produced by α-polymerization of chloroprene as the main raw material. It is widely used in weather-resistant products, viscose soles, coatings and rocket fuels. It has good physical and mechanical properties, and is resistant to oil, heat, flame, sunlight, ozone, acid and alkali, and chemical reagents. Its disadvantages are poor cold resistance and storage stability. It has high tensile strength, elongation, reversible crystallinity, and good adhesion.

[0003] During the production process of chloroprene rubber, a frozen film is formed through freezing and conversion. At this time, the chloroprene latex is transformed from a liquid to a solid film. This film is washed with water and extruded to form a soft film with a thickness of about 0.2 mm. This film has the characteristics of multiple micropores, low strength, and easy adhesion. It is very easy to be wrapped around the extrusion roller. If it is not discovered in time, it will cause damage to the equipment. Manual monitoring is generally used in the production of chloroprene rubber. Manual monitoring is inefficient and the effect is not ideal. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model discloses a device for detecting a broken belt of a chloroprene rubber film, comprising a mounting frame 1 on which a squeezing roller 2 is installed, two mounting rods 3 are installed on the top of the mounting frame 1, the ends of the two mounting rods 3 are fixedly connected to the same connecting rod 4, at least two movable frames 5 are detachably provided on the connecting rod 4, and a photoelectric detection switch 12 for detecting whether the chloroprene rubber film is broken is installed on the front side of each movable frame 5 in a liftable manner.

[0018] The photoelectric detection switch 12 is a diffuse reflection photoelectric switch.

[0019] The photoelectric detection switch 12 is electrically connected to a controller that controls the emergency stop device.

[0020] A plurality of diffuse reflection type photoelectric switches are used to illuminate the rubber film. When the photoelectric switch receives the light reflected by the rubber film, it is considered that the rubber film is intact and no rubber is entangled with the squeeze roller 2. When the photoelectric switch does not receive the light reflected by the rubber film, it is considered that the rubber film is broken and the squeeze roller 2 is entangled with rubber.

[0021] Since the rubber film has microporous properties, it may happen that the rubber film is intact, but the light from the photoelectric switch passes through the micropores without reflecting light, which may lead to a misjudgment that the rubber film is broken. Therefore, the program uses the fact that two adjacent photoelectric switches cannot receive reflected light as a basis for judgment. The relevant equipment is interlocked and stopped urgently based on this signal.

[0022] Specifically, the movable frame 5 is in a U-shape as a whole, and a clamping slot 6 is formed at the bottom thereof. The movable frame 5 is clamped on the connecting rod 4 through the clamping slot 6 .

[0023] One side of the movable frame 5 is threadedly connected with an adjusting screw 13 whose end extends into the clamping slot 6 .

[0024] In this embodiment, when the movable frame 5 is clamped on the connecting rod 4 through the clamping slot 6, the position of the movable frame 5 on the connecting rod 4 can be adjusted to adjust the distance between adjacent photoelectric detection switches 12 to avoid interference.

[0025] When the position of the movable frame 5 is adjusted, the adjusting screw 13 is tightened, and the end of the adjusting screw 13 can press against the connecting rod 4, so that the movable frame 5 is not easy to slide relative to the connecting rod 4, so that the position of the movable frame 5 and the photoelectric detection switch 12 is maintained.

[0026] Specifically, a fixing rod 7 is fixedly connected to the front side of the movable frame 5, a through hole 8 is formed at the end of the fixing rod 7, and a strip groove 9 connected to the through hole 8 is formed at the top and bottom of the fixing rod 7. The through hole 8 is movably connected to a lifting rod 10 whose two ends pass through the strip groove 9 and the through hole 8, and the bottom end of the lifting rod 10 is fixedly connected to a photoelectric detection switch 12. The through hole 8 is formed with an internal thread, and the through hole 8 is connected to a stud 11 for clamping the lifting rod 10 through its internal thread.

[0027] In this embodiment, a hexagonal hole or a cross slot is provided at the end of the stud 11. When the stud 11 is loosened, the height of the lifting rod 10 can be adjusted, so that the height of the photoelectric detection switch 12 is adjusted. After the height adjustment is completed, the stud 11 can be tightened.

[0028] Specifically, a strip hole 14 is formed on the top of one end of the mounting rod 3 away from the connecting rod 4 , and the mounting rod 3 is mounted on the mounting frame 1 through the cooperation between the strip hole 14 and the bolt.

[0029] In this embodiment, the arrangement of the strip-shaped hole 14 can adjust the distance between the connecting rod 4 and the squeezing roller 2 when the bolts are used for installation.

[0030] In summary, the device for detecting a broken chloroprene rubber film detects the extruded chloroprene rubber film through a plurality of photoelectric detection switches 12 to determine whether the film is broken, thereby improving the efficiency of detecting a broken chloroprene rubber film.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
