[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In one embodiment, see Figure 1-Figure 9 , a label paper light transmittance detector, including a fixed base 1, the fixed base 1 is a flat structure for fixing different devices, a suction cup is arranged on the lower surface of the fixed base 1 or fixing bolt holes are arranged at the four corners of the fixed base 1, and the fixed base 1 is stably fixed on the workbench by the suction cup or bolt connection, so that no vibration occurs in the subsequent detection process, and the change of the detection data caused by the change of the distance between the label paper and the light measuring sensor 20 caused by the vibration is avoided. The fixed base 1 is provided with a splitting mechanism 2, a light measuring mechanism 3 and a winding mechanism 4 from left to right;

[0026] The splitting mechanism 2 is arranged at the left end of the fixed base 1, and includes a first vertical plate 7 fixedly connected to the fixed base 1. The first vertical plate 7 is vertically arranged on the left side of the rear side of the fixed base 1. A porous roller 8 arranged in a front-to-back direction is respectively arranged on the upper and lower sides of the first vertical plate 7. The porous roller 8 is a hollow structure and a plurality of holes for ventilation are evenly distributed on the side wall. A placement rack 5 is arranged at the left end of the first vertical plate 7. The placement rack 5 is an L-shaped structure. The vertical rod of the placement rack 5 is fixed to the rear side of the fixed base 1 and is tilted to the upper left. The cross bar of the placement rack 5 is arranged at the upper end of the vertical rod in a front-to-back direction. By setting the vertical rod of the placement rack 5 to an angle facing the upper left, the detector can increase the upper operating space as much as possible while keeping the occupied volume of the fixed base 1 small, so that the label paper can be pulled out stably, and the connection relationship between the placement rack 5 and the fixed base 1 can also be designed to be a rotating connection, and an angle locking device is designed at the connection position. When detection is required, the placement rack 5 is rotated to the left so that the placement rack 5 is unfolded, thereby facilitating subsequent testing. The roll 6 can be put in, but when the whole device is not needed, the placement frame 5 can be rotated to the right and close to the first vertical plate 7, which reduces the volume of the whole detector and facilitates the storage of the detector. The roll 6 to be tested with the label paper wound on it can be put on the placement frame 5 from front to back. At this time, the label paper can be pulled out from the roll 6 to be tested, and the label paper can be passed through the gap between the upper and lower porous rollers 8. The upper and lower porous rollers 8 can just clamp the label paper, and in order to improve the clamping efficiency, two holes can be set on the front and back sides of the porous rollers 8. A circle of rubber ring 16 increases the friction force, the lower porous roller 8 rotates clockwise, and the upper porous roller 8 rotates counterclockwise. At this time, the display layer 23 above the label paper is attached to the lower surface of the upper porous roller 8, and the base layer 24 below the label paper is attached to the lower surface of the porous roller 8. A suction head 9 that can generate negative pressure is arranged inside the porous roller 8. The suction force of the suction head 9 is transmitted to the label paper through the air holes on the surface of the porous roller 8, so that the porous roller 8 can absorb the label paper, thereby separating the display layer 23 and the base layer 24 of the label paper;

[0027] The photometric mechanism 3 includes a second vertical plate 25 fixedly connected to the fixed base 1, the second vertical plate 25 is vertically arranged in the middle of the rear side of the fixed base 1, and is rotatably connected to a main shaft 31 arranged in a front-to-back direction above the second vertical plate 25, the front end of the main shaft 31 is fixedly connected to the rotating plate 19, and a photometric sensor 20 arranged in a front-to-back direction is arranged in the middle of the upper part of the rotating plate 19, and the left and right sides of the photometric sensor 20 are chamfered so that the surface of the display layer 23 can better fit on the photometric sensor 20, and in order to improve the guiding effect, first guide rods 21 are arranged on the left and right sides of the photometric sensor 20, and the height of the first guide rods 21 is higher than the photometric sensor 20, so that after the first guide rods 21 transfer the display layer 23 to the lower surface of the photometric sensor 20, the photometric sensor 20 can be tightly attached to the upper surface of the display layer 23, and rotate. A light emitter 22 facing forward and backward is provided in the middle of the lower part of the board 19, and a light emitting groove facing forward and backward is provided in the middle of the upper surface of the light emitter 22, so that the light emitter 22 can generate uniform and parallel light to illuminate the display layer 23 above, and the light can pass through the display layer 23 to reach the light measuring sensor 20, so that the light transmission effect of the display layer 23 can be judged by the light measuring sensor 20. A second guide rod 30 is provided at the lower middle part of the second vertical plate 25, and the second guide rod 30 is arranged in a forward and backward direction. The base layer 24 of the label paper will pass through the second guide rod 30 from below the second guide rod 30. On the one hand, the light measuring process of the label paper display layer 23 can be completed by the light measuring mechanism 3, and on the other hand, the separated display layer 23 and the base layer 24 are separated by a certain distance by the first guide rod 21 and the second guide rod 30 for easy light transmission detection.

[0028] The winding mechanism 4 includes a third vertical plate 32 fixed to the right side of the fixed base 1. The third vertical plate 32 is vertically arranged at the right end of the rear side of the fixed base 1, and a rotating shaft 33 arranged in a front-to-back direction is arranged in the middle of the third vertical plate 32. A winding roller 35 that rotates synchronously with the rotating shaft 33 is sleeved on the outer side of the rotating shaft 33. When the display layer 23 and the base layer 24 of the label paper complete the light transmittance detection, they will be bonded together again. At this time, the bonded label paper will be wound on the outside of the winding roller 35. The winding roller 35 can drive the label paper to move in the detector as the rotating shaft 33 rotates, providing the power for winding.

[0029] In one case of the present embodiment, the upper end of the first vertical plate 7 is rotatably connected to a rotating seat 17, and the rotating seat 17 can rotate forward and backward relative to the first vertical plate 7, and is rotatably connected to the rear end of the upper porous roller 8 on the side of the rotating seat 17, and the porous roller 8 can rotate left and right relative to the rotating seat 17. Therefore, when the porous roller 8 rotates forward together with the rotating seat 17, the upper porous roller 8 can fall on the lower porous roller 8, and the label paper is pressed by gravity. In addition, a limiting bracket 18 is provided above the rear side surface of the first vertical plate 7. When the label paper needs to be clamped, the upper porous roller 8 can be flipped to the rear side. At this time, the limiting bracket 18 can support the porous roller 8. At this time, the two porous rollers 8 are separated, providing the operator with a larger space for clamping the label paper.

[0030] In one case of the present embodiment, a support wheel 48 is arranged directly below the porous roller 8 below, and the support wheel 48 is rotatably connected to the upper surface of the fixed base 1. The support wheel 48 can support the porous roller 8 below to prevent the porous roller 8 from being in a cantilever beam state and affecting normal rotation. The side of the suction head 9 that is in contact with the inner wall of the porous roller 8 is arranged to be an arc surface, and in order to reduce the demand for negative pressure strength, only an arc surface corresponding to a 90° central angle is arranged. Therefore, the upper suction head 9 is facing the position directly below and to the right, and the lower suction head 9 is facing the position directly above and to the right, so that the position of the porous roller 8 that contacts the label paper can generate negative pressure, but the surface of the porous roller 8 that does not contact the label paper has no negative pressure, thereby reducing the demand for negative pressure of the suction head 9. In order to facilitate the flipping of the porous roller 8, fixed blocks 13 fixedly connected to the fixed base 1 are arranged on the left and right sides of the lower porous roller 8, and the fixed blocks 13 are slidably connected to the protruding slide rod 14 arranged in a front-to-back direction. The end is fixedly connected to the transverse shift seat 15, and a gripper is provided on the front side of the transverse shift seat 15, by which the operator can conveniently pull the transverse shift seat 15 forward and backward, and a transverse shift plate 11 is vertically provided in the middle of the upper surface of the transverse shift seat 15, and fixed air pipes 10 are provided on the upper and lower sides of the transverse shift plate 11, and the rear end of the fixed air pipe 10 is connected to the suction head 9, and a three-way valve 12 is provided in the middle of the front side of the transverse shift plate 11, and the front ends of the two fixed air pipes 10 are connected to the three-way valve 12, and the external air source is connected to the three-way valve 12, so that the two suction heads 9 can be connected to one air source, so only one air pressure control device is needed, when the air source is turned on, due to the provision of the three-way valve 12, the upper and lower suction heads 9 can generate negative pressure at the same time, which reduces the operating difficulty of the entire device, and also makes it only necessary to provide an external air pipe to be connected to the three-way valve 12 when installing the entire detector, which reduces the installation difficulty of the entire detector and makes the air pressure control of the suction head 9 more convenient.

[0031] In one case of the present embodiment, the left end of the deflection plate 26 is fixedly connected to the rear end of the main shaft 31, and the right end of the deflection plate 26 is rotatably connected to the lower end of the pull plate 27. The upper end of the pull plate 27 is slidably connected to a limit slide bar 28 set in the front and rear directions, and a limit hole 29 is set above the second vertical plate 25. After pulling the pull plate 27 upward and inserting the limit slide bar 28 into the limit hole 29, the rotating plate 19 is in a state facing the upper right, so that the display layer 23 can be better transferred from the porous roller 8 on the left to the winding roller 35 on the right.

[0032] The first bevel gear 38 is meshed with the second bevel gear 39, and the second bevel gear 39 is fixed to the rear end of the shaft 33. Therefore, the driving motor 37 can drive the shaft 33 to rotate by means of gear transmission, thereby realizing the effect of rotating the winding roller 35.

[0033] In one case of this embodiment, the clamping assembly 34 includes rings 41 arranged on the front and rear sides of the rotating shaft 33, the rear ring 41 is fixedly connected to the rotating shaft 33, and the front ring 41 slides forward and backward along the rotating shaft 33. A clamping spring 43 is arranged between the front and rear rings 41, and the clamping spring 43 is sleeved on the outside of the rotating shaft 33. A connecting plate 42 is rotatably connected to the outside of the ring 41. The three connecting plates 42 are evenly distributed on the outside of the ring 41 along the center of the rotating shaft 33. The end of the connecting plate 42 away from the ring 41 is rotatably connected to the clamping plate 44. Therefore, when the winding roller 35 is sleeved on the outside of the clamping plate 44, the clamping spring 43 will push the ring 4 1 are away from each other, so that the clamping plate 44 is pressed against the inner wall of the winding roller 35. After the clamping plate 44 is pressed against the inner wall of the winding roller 35, since the connecting plates 43 are provided on both the front and rear sides, the fixing process is completed by the same clamping spring 43. At this time, the three clamping plates 44 are all tightly attached to the outside of the winding roller 35, so that the winding roller 35 is in a state parallel to the rotating shaft 33, and the fixing effect of the winding roller 35 is completed. A handle 40 is provided on the front side of the front side ring 41. The operator can pull the front side ring 41 forward by the handle 40, so that the clamping plates 44 are close to each other, which is convenient for the winding roller 35 to be sleeved on the outside of the clamping plates 44.

[0034] In one case of this embodiment, the clamping assembly 36 includes a hanging plate 47 rotatably connected to the front side above the third vertical plate 32, the end of the hanging plate 47 is rotatably connected to the mounting frame 45, and the mounting frame 45 is rotatably connected to the pressure roller 46. When the hanging plate 47 rotates toward the front side, the pressure roller 46 can fall above the winding roller 35 under the action of gravity, and the gravity of the pressure roller 46 applies pressure to the winding roller 35. The pressure roller 46 is designed to be a roller body with a rubber layer on the outside, so that the pressure roller 46 falls outside the winding roller 35 on which the label paper is wound. After the part is installed, there is a sufficiently large friction between the pressure roller 46 and the winding roller 35, so that the pressure roller 46 rotates synchronously with the winding roller 35, so that the pressure roller 46 only provides effective pressure and will not affect the winding of the label paper onto the outside of the winding roller 35. When the hanging plate 47 rotates to the rear side, the hanging plate 47 will rotate to a state of being in contact with the upper end of the third vertical plate 32. At this time, the mounting frame 45 will rotate to the rear side of the third vertical plate 32 and be blocked. At this time, the pressure roller 46 is completely disengaged from the winding roller 35, which can facilitate the installation of the winding roller 35.

[0035] During the implementation of this embodiment, a controller is set on the front side of the upper surface of the fixed base 1, and the normal operation of the light measuring sensor 20, the light emitter 22, the drive motor 37 and the suction head 9 is controlled by the controller, and the front end of the tee 12 is connected to the air source to connect the entire detector to electricity.

[0036] To install the label paper, first flip the pressure roller 46 to the rear side so that the pressure roller 46 rotates to the rear side of the third vertical plate 32. The operator pulls the handle 40 to the front side with his left hand, and the clamping plate 44 is pressed against the outside of the shaft 33. At this time, the operator presses the clamping plate 44 with his right hand, and picks up the winding roller 35 with his left hand, and puts the winding roller 35 on the outside of the clamping plate 44 from front to back. The operator releases his right hand and puts the winding roller 35 on the middle part of the shaft 33. The winding roller 35 is fixed, and the roll 6 to be tested is taken out and put on the placement rack from front to back. 5, pull the transverse shift seat 15 forward, move the suction head 9 to the front side of the porous roller 8, rotate the porous roller 8 above the first vertical plate 7, then pull out the free end of the label paper, put the label paper on the porous roller below, manually tear off the label paper at the free end, so that the display layer 23 and the base layer 24 are separated, the display layer 23 passes through the gap between the photometric sensor 20 and the light emitter 22, and the base layer 24 passes from under the second guide rod 30, and then the display layer 23 and the base layer 24 are attached together again and fixed to the outside of the winding roller 35.

[0037] The label paper is fixed, and the pressure roller 46 is flipped forward. The pressure roller 46 falls on the outside of the winding roller 35 of the fixed label paper. At this time, the porous roller 8 is flipped forward, and the upper porous roller 8 is pressed on the top of the label paper. The transverse shift seat 15 is pushed backward, and the suction head 9 moves to the inside of the porous roller 8. The pull plate 27 is pulled upward, and the limiting slide bar 28 is inserted into the limiting hole 29. At this time, the rotating plate 19 is tilted to the upper right. At this time, the display layer 23 and the base layer 24 of the label paper are separated, and the display layer 23 is attached to the lower surface of the upper porous roller 8, and the base layer 24 is attached to the upper surface of the lower porous roller 8. The label paper is fixed.

[0038] Detection processing, start the photometric sensor 20 and the light emitter 22, and connect the relevant data of the photometric sensor 20 and the light emitter 22 to the computer for data collection. First, open the suction head 9, the suction head 9 generates negative pressure, and the porous roller 8 absorbs the display layer 23 and the base layer 24 of the label paper. Then start the drive motor 37. The drive motor 37 drives the winding roller 35 to rotate clockwise through the gear transmission. The label paper is wound in the winding roller 35. Therefore, the label paper is transferred from the outside of the roll 6 to the outside of the winding roller 35 from left to right. During the movement of the label paper, the label paper is separated due to the adsorption of the porous roller 8. Effect, the display layer 23 is subjected to light transmittance detection after passing the positions of the photometric sensor 20 and the light emitter 22, and because the label paper is initially torn open at the free end manually, and the second guide rod 30 pulls the base layer 24 downward, and the winding roller 35 is at the top to wind up the display layer 23, the suction force of the porous roller 8 can be used to relatively easily separate the opened label paper, and because the porous roller 8 is passively rotated with the label paper, the label paper is always in a taut state, ensuring that the label paper passes through the photometric sensor 20 and the light emitter 22 in a relatively straight manner.

[0039] After the label paper has been tested, it is necessary to take out the tested label paper and organize and fix the entire detector.

[0040] The winding roller 35 is disassembled and the pressure roller 26 is flipped backward again so that the mounting frame 25 is against the rear side of the third vertical plate 32. The winding roller 35 is directly pulled outward, one of the clamping plates 44 is rotated to the top, and the pressure roller 26 is rotated to the front again. At this time, the pressure roller 26 falls on the clamping plate 44 above. The rotating shaft 33 is slightly rotated so that the side of the mounting frame 45 is fitted against the side of the clamping plate 44. At this time, the clamping plate 44 and the mounting frame 45 are fixed by binding tape, so that the entire winding mechanism 4 is limited in position, and the pressure roller 26 is in an unloaded state and is not pressed, thereby ensuring the surface roundness of the pressure roller 26.

[0041] The light measuring mechanism 3 is fixed, and the limit slide bar 28 is pulled out from the limit hole 29. At this time, the rotating plate 19 rotates to a horizontal state under the action of gravity, and the elastic strap is put on the outside of the first guide rod 21 and the second guide rod 30. The angle of the rotating plate 19 is also locked, and the limit slide bar 28 is slightly pushed to the front side. The limit slide bar 28 is against the rear side of the third vertical plate 32, and the pull plate 27 will be slightly deflected to the rear side, and the pull plate 27 is fixed to the deflection plate 26 by the strap. At this time, the angles of the pull plate 27 and the deflection plate 26 are fixed, and the angle of the rotating plate 19 on the front side is also fixed. At this time, the entire light measuring mechanism 3 is locked, and there will be no shaking problem.

[0042] The splitting mechanism 2 is fixed, and the transverse shift seat 15 is pulled forward to disengage the suction head 9 and the porous roller 8. At this time, the upper porous roller 8 is slightly lifted, and a rubber pad for buffering is taken out and placed between the upper and lower porous rollers 8, and a strap is taken out to bind the upper and lower porous rollers 8 together, and the transverse shift seat 15 is moved in the opposite direction, and the suction head 9 is inserted into the porous roller 8, and some foam for buffering is taken out and stuffed into the porous roller 8, so that the gap between the suction head 9 and the porous roller 8 is stuffed with foam, and the suction head 9 and the porous roller 8 cannot be relatively displaced. The empty roll 6 to be tested is pulled out from the placement rack 5. The placement rack 5 can be rotated clockwise at this time so that the placement rack 5 is leaning against the left side of the first vertical plate 7. The placement rack 5 and the first vertical plate 7 are tied together by a strap. If the placement rack 5 is designed to be fixed, the step of fixing the placement rack 5 here can be omitted. At this time, the entire detector is fixed and can be placed in a storage cabinet. If long-distance transportation or handling is required, the entire fixed detector can be placed in a transfer box for movement. Since each component is effectively fixed, the shaking during transportation will not damage the detector.

[0043] The present invention is applicable to a label paper light transmittance detector, which is provided with a porous roller 8 to absorb the label paper, so that the label paper is separated into a display layer 23 and a base layer 24 after passing through the porous roller 8, so that the light measuring sensor 20 can perform light transmittance detection processing on the display layer 23, and after the entire display layer 23 is separated, only the upper surface is in contact with the light measuring sensor 20 and the first guide rod 21, so that the side surface of the display layer 23 coated with glue below does not contact other components, so it will not affect the subsequent viscosity of the display layer 23, that is, the label paper can be pasted normally after the detection is completed, and the performance will not be affected.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
