Description

Technical Field

[0001] This utility model belongs to the field of tobacco processing machinery technology, and relates to a series diffuse reflection photoelectric switch bracket for an air-filled roller conveyor. Background Technology

[0002] Air-filled roller conveyors are roller conveyor equipment that combines pneumatic technology or air pressure environment control. They are mainly used for the efficient and stable transportation of tobacco shreds, finished cigarettes, or other packaging materials in the tobacco production process. The series-type diffuse reflection photoelectric switch on the air-filled roller conveyor provides signal and control support for functions such as temporary storage and stacking of goods on the conveyor. The series-type diffuse reflection photoelectric switch used in tobacco production sites uses two infrared detection mirrors for photoelectric reaction signal detection and transmission. Therefore, the proper functioning of the series-type diffuse reflection photoelectric switch on the air-filled roller conveyor depends on strict installation requirements: both infrared detection mirrors must be transparent (non-detection objects must not be obstructed). The distance between the two detection mirrors is 50mm. Due to the divergence of the detection light source, on-site measurements show that the distance between the two rollers must be ≥80mm.

[0003] However, due to various complex situations that may arise during the installation, adjustment, and tensioning of air-supported roller conveyors, the spacing between each pair of smooth rollers may not be exactly the same. When the spacing between the two smooth rollers containing the series-connected diffuse reflection photoelectric switch is less than 60mm, the series-connected diffuse reflection photoelectric switch will not function properly.

[0004] Therefore, a device is needed to determine the spacing between the pairs of smooth rollers in an air-supported roller conveyor to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical solution adopted by this utility model to solve the technical problem is: a series diffuse reflection photoelectric switch bracket for an air-supported roller conveyor, comprising: a horizontal plate and a vertical plate, the end face of the horizontal plate being connected to the side face of the vertical plate to form an L-shaped curved plate; the horizontal plate is provided with at least two sets of parallel elongated first mounting holes, the first mounting holes being used for detachable connection to the roller conveyor; the vertical plate is provided with a second mounting hole for detachable connection to the series diffuse reflection photoelectric switch, and the vertical plate is provided with a through hole for mounting the transmitter and / or receiver of the series diffuse reflection photoelectric switch; the length of the first mounting hole is not less than 30mm.

[0006] Preferably, the second mounting hole is two parallel elongated holes, and the length direction of the second mounting hole is set in the vertical direction.

[0007] More preferably, the orifice of the through hole is a U-shaped groove with an open top, and the through hole is located between the two second mounting holes.

[0008] Preferably, the length direction of the first mounting hole is perpendicular to the surface of the vertical plate.

[0009] Preferably, the horizontal plate is connected to the vertical plate by welding, riveting, or bolting.

[0010] The beneficial effects of this utility model are:

[0011] This invention solves the problem that the distance between two rollers in a roller conveyor cannot be fixed (due to issues with initial installation, subsequent adjustment, and tensioning of the roller drive chain), and reduces the installation distance between two rollers from >60mm to >30mm. This invention also makes the installation, maintenance, and adjustment of series diffuse reflection photoelectric switches simpler, more convenient, and faster. Attached Figure Description

[0017] The relevant technologies of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1-4 As shown, a series diffuse reflection photoelectric switch bracket for an air-filled roller conveyor according to this embodiment includes: a horizontal plate 1 and a vertical plate 2. The end face of the horizontal plate 1 is connected to the side face of the vertical plate 2 to form an L-shaped curved plate. The horizontal surface of the L-shaped curved plate can be used to connect with the roller conveyor, and the vertical surface of the L-shaped curved plate can be used to install the series diffuse reflection photoelectric switch 5.

[0019] The horizontal plate 1 is provided with at least two sets of parallel elongated first mounting holes 3. The first mounting holes 3 are used for detachable connection of the roller conveyor. The elongated first mounting holes 3 can adjust the installation position and installation distance between the horizontal plate 1 and the roller conveyor, thereby adjusting the light irradiation stroke length between the series diffuse reflection photoelectric switches 5.

[0020] The vertical plate 2 is provided with a second mounting hole 4 for detachable connection of the series diffuse reflection photoelectric switch 5, and the vertical plate 2 is provided with a through hole 6 for mounting the transmitter and / or receiver of the series diffuse reflection photoelectric switch 5.

[0021] The length of the first mounting hole 3 is not less than 30mm. The length of the first mounting hole 3 can increase the installation distance between the two roller tracks, thereby increasing the adjustable distance of the original installation distance. Therefore, the installation distance between the two roller tracks can be reduced from a minimum of 60mm to a minimum of 30mm.

[0022] Furthermore, the second mounting hole 4 consists of two parallel elongated holes, with the length of the second mounting hole 4 set vertically. The elongated design of the second mounting hole 4 allows for adjustment of the mounting height of the series-connected diffuse reflection photoelectric switch 5, and makes installation more convenient and faster.

[0023] Furthermore, the orifice 6 is a U-shaped groove with an open top. The through hole 6 is located between the two second mounting holes 4. The U-shaped through hole 6 can meet the installation requirements of the transmitter and / or receiver when adjusting the installation height of the series diffuse reflection photoelectric switch 5. On the other hand, it can quickly install the transmitter and / or receiver from top to bottom during installation, making installation and debugging more convenient and faster.

[0024] Furthermore, the length direction of the first mounting hole 3 is perpendicular to the surface of the vertical plate 2.

[0025] Furthermore, the horizontal plate 1 can be connected to the vertical plate 2 by welding, riveting, or bolting.

[0026] Example

[0027] In this embodiment, considering the mechanical structure of the air-supported roller conveyor and the reflective physical characteristics of the optical rollers, and taking advantage of the design requirement that the series-type diffuse reflection photoelectric switch reflectors are installed on an installation line with a width of 20mm, this embodiment is divided into two parts: By welding the horizontal plate 1 and the vertical plate 2 into an L-shaped curved plate photoelectric switch bracket, the photoelectric switch bracket is installed between two pairs of optical rollers of the air-supported roller conveyor through the first mounting hole 3 on the horizontal plate 1. Then, the series-type diffuse reflection photoelectric switch 5 is set between two pairs of optical rollers through the vertical plate 2. Using the elongated hole installation method of the first mounting hole 3, the position of the photoelectric switch between two pairs of optical rollers can be adjusted left and right in the horizontal direction. Using the elongated hole and through hole 6 of the second mounting hole 4, the height of the photoelectric switch can be adjusted in the vertical direction by lifting and lowering, thus eliminating the signal interference of the optical rollers on the diffuse reflection light waves.

[0028] In summary, this utility model solves the problem of determining the distance between two rollers of a roller conveyor during the initial installation, subsequent adjustment, and tensioning of the roller conveyor drive chain by setting horizontal and vertical elongated holes on the horizontal and vertical plates of the L-shaped curved plate switch bracket, making the installation, maintenance, and adjustment of the series diffuse reflection photoelectric switch simpler, more convenient, and faster.

[0029] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
