[0035] In this embodiment, as Figure 1 and Figure 2As shown in the figure, an auxiliary calibration device for a laser scanner during the transportation of packaged rice includes a conveyor body 1 and a laser scanner body 2. A trigger assembly 3 is installed on the conveyor body 1. The trigger assembly 3 is used to expand the triggering range of the bagged rice on the laser scanner body 2. The trigger assembly 3 includes a support frame 31, a connecting piece 32, a rotating shaft 33, a trigger plate 34, and a resetting piece 35. The bottom end of the support frame 31 is inserted into the card slot of the conveyor body 1. The support frame 31 is connected to the conveyor body 1 through the connecting piece 32. The rotating shaft 33 is rotatably connected to the support frame 31 through a bearing. The top protrusion of the trigger plate 34 is fixedly connected to the rotating shaft 33. The resetting piece 35 is used to drive the trigger plate 34 to reset.

[0036] Thus, the support frame 31 is installed in the card slot of the conveyor body 1 through the connecting piece 32. When the conveyor body 1 is used to transport the bagged rice, as the bagged rice moves horizontally, it pushes the trigger plate 34. Under the action of the thrust of the bagged rice, the trigger plate 34 rotates clockwise in the support frame 31 through the rotating shaft 33. When the trigger plate 34 deflects to the bottom of the laser scanner body 2, it triggers the laser scanner body 2. The laser scanner body 2 is intermittently triggered by the trigger plate 34 to count the bagged rice. The bottom width of the trigger plate 34 is adapted to the conveyor body 1. When the bagged rice is transported on the conveyor body 1, it will push the trigger plate 34 to rotate, thereby preventing the laser scanner body 2 from missing the count of the bagged rice.

[0037] Furthermore, the conveyor body 1 is used to transport the bagged rice, and the laser scanner body 2 is used to scan the barcodes on the packaging bags of the bagged rice.

[0038] In some embodiments, as Figure 3 shown, the resetting piece 35 includes a fixing plate 351, a sliding rod 352, a circular plate 353, a rack plate 354, a gear 355, and an elastic member 356. The bottom end of the fixing plate 351 is fixedly connected to the support frame 31. The sliding rod 352 is inserted into the through hole of the fixing plate 351. The central hole of the circular plate 353 is fixedly connected to the sliding rod 352. The rack plate 354 is fixedly connected to the end of the sliding rod 352 away from the circular plate 353. The gear 355 is meshed with the rack plate 354. The central hole of the gear 355 is fixedly connected to the rotating shaft 33. The elastic member 356 is sleeved on the outer periphery of the sliding rod 352. The elastic member 356 is located between the circular plate 353 and the fixing plate 351.

[0039] Furthermore, the fixing plate 351 is in a right-angled shape. A through hole adapted to the sliding rod 352 is machined on the fixing plate 351. The circular plate 353 is fixed to one end of the sliding rod 352. The design of the circular plate 353 prevents the elastic member 356 from separating from the sliding rod 352. The sliding rod 352 and the rack plate 354 move together. The design of the elastic member 356 is used to drive the sliding rod 352 to reset in the fixing plate 351.

[0040] In some embodiments, as Figure 2 shown, the connecting member 32 includes a right-angle plate 321 and a bolt 322. The right-angle plate 321 is fixedly connected to the support frame 31, and the right-angle plate 321 is connected to the conveyor body 1 through the bolt 322.

[0041] Furthermore, two right-angle plates 321 are symmetrically arranged on both sides of the support frame 31. After the bolt 322 connects the right-angle plate 321 and the conveyor body 1, the support frame 31 is then positioned in the card slot on the top of the conveyor body 1.

[0042] In some embodiments, as Figure 1 shown, a roller 11 is installed in the conveyor body 1, and a conveyor belt 12 is installed on the roller 11. The conveyor belt 12 is used to convey bagged rice.

[0043] Furthermore, the roller 11 rotates in the conveyor body 1 through bearings. The roller 11 supports the conveyor belt 12. The roller 11 and the conveyor belt 12 are components of the conveyor body 1 and are used to transport bagged rice.

[0044] In some embodiments, as Figure 4 shown, a loosening prevention component 4 is installed on the conveyor body 1. The loosening prevention component 4 is used to enhance the connection strength between the conveyor belt 12 and the roller 11. The loosening prevention component 4 includes a sliding seat 41, a strip-shaped plate 42, a pressing roller 43, and an adjusting member 44. The sliding seat 41 is fixedly connected to the feeding end of the conveyor body 1. The strip-shaped plate 42 is inserted into the sliding groove of the sliding seat 41. The pressing roller 43 is rotatably connected to the strip-shaped plate 42 through a pin shaft. The outer circumference of the pressing roller 43 abuts against the conveyor belt 12. The adjusting member 44 is used to fix the position of the strip-shaped plate 42 in the sliding seat 41.

[0045] Furthermore, the sliding seat 41 is U-shaped. Two strip-shaped plates 42 are arranged on both sides of the pressing roller 43. A sliding groove is machined on the outer wall of the strip-shaped plate 42. By pressing the conveyor belt 12 tightly with the pressing roller 43, the conveyor belt 12 is prevented from loosening.

[0046] In some embodiments, as Figure 5 shown, the adjusting member 44 includes a connecting pin 441 and a nut 442. The connecting pin 441 is inserted into the sliding groove of the strip-shaped plate 42. One end of the connecting pin 441 is fixedly connected to the conveyor body 1. The nut 442 is connected to the end of the connecting pin 441 away from the conveyor body 1.

[0047] Furthermore, the outer wall of the connecting pin 441 is machined with threads. The nut 442 is used to determine the position of the strip-shaped plate 42 on the outer wall of the connecting pin 441.

[0048] In some embodiments, as Figure 3As shown, a guiding rod 354a is fixedly connected to the rack plate 354, and the guiding rod 354a is inserted into the circular hole of the fixed plate 351.

[0049] Furthermore, the guiding rod 354a and the sliding rod 352 are designed in parallel, and the use of the guiding rod 354a restricts the lateral movement of the sliding rod 352 in the fixed plate 351.

[0050] In some embodiments, such as Figure 3 As shown, the elastic member 356 is a compression spring.

[0051] Furthermore, the elastic member 356 is designed as a compression spring, which is convenient for driving the sliding rod 352 to reset in the fixed plate 351.

[0052] In some embodiments, such as Figure 2 As shown, the bottom of the trigger plate 34 is processed into an arc shape.

[0053] Furthermore, the bottom of the trigger plate 34 is designed to be arc-shaped, which is convenient for the bagged rice to pass between the trigger plate 34 and the conveyor belt 12.

[0054] In some embodiments, such as Figure 1 As shown, the surface of the conveyor belt 12 is processed with abrasive patterns 121, and the abrasive patterns 121 are used to increase the friction between the bagged rice and the conveyor belt 12.

[0055] Furthermore, the abrasive patterns 121 are processed into strips, and the abrasive patterns 121 prevent the bagged rice from shifting arbitrarily on the conveyor belt 12.

[0056] The working principle of the present application will be described below with a relatively preferred embodiment:

[0057] First, insert the support frame 31 into the card slot of the conveyor body 1. Subsequently, use the bolt 322 to connect the right-angle plate 321 and the conveyor body 1. Then, install the trigger plate 34 directly above the conveyor belt 12. When using the conveyor body 1 to transport bagged rice, the bagged rice is placed on the reciprocating conveyor belt 12. When the bagged rice abuts against the outer wall of the trigger plate 34, as the conveyor belt 12 moves, the bagged rice pushes the trigger plate 34 to rotate clockwise in the support frame 31 through the rotating shaft 33. At this time, the gear 355 rotates with the rotating shaft 33 to drive the rack plate 354 to move horizontally. When the rack plate 354 drives the slide rod 352 to move in the fixed plate 351, the slide rod 352 drives the circular plate 353 to compress the elastic member 356. When the trigger plate 34 rotates clockwise to the bottom of the laser scanning unit body 2, the laser scanning unit body 2 is triggered. After the bagged rice is separated from the trigger plate 34, the trigger plate 34 automatically resets under the action of the elastic member 356. The laser scanning unit body 2 is intermittently triggered by the trigger plate 34, and then the laser scanning unit body 2 counts the bagged rice. When the conveyor belt 12 becomes loose, move the strip plate 42 in the slide seat 41. The strip plate 42 drives the pressure roller 43 to move towards the conveyor belt 12. The outer circumference of the pressure roller 43 abuts tightly against the outer wall of the conveyor belt 12. Then, rotate the nut 442 on the connecting pin 441 to fix the position of the strip plate 42 on the connecting pin 441. Thus, the conveyor belt 12 is tightened by using the pressure roller 43 pressing against it.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
