Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light transmission detection, and specifically relates to a label paper light transmission detector. BACKGROUND

[0002] Label paper is a material widely used in the fields of commodity packaging, logistics transportation, office documents and the like.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0025] In one embodiment, referring to Figures 1-9 A label paper light transmittance detector includes a fixed base 1, which is a flat plate structure for fixing different devices. A suction cup is arranged on the lower surface of the fixed base 1, or fixed bolt holes are arranged at the four corners of the fixed base 1. The fixed base 1 is stably fixed on the workbench by the suction cup or bolt connection, so that the subsequent detection process will not vibrate, and the change of the detection data caused by the change of the distance between the label paper and the light measurement sensor 20 due to vibration is avoided. The fixed base 1 is sequentially provided with a split mechanism 2, a light measurement 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 with the fixed base 1. The first vertical plate 7 is vertically arranged at the left side of the rear side edge of the fixed base 1. A plurality of perforated rollers 8 are arranged at the upper and lower sides of the first vertical plate 7 and face forward and backward. The perforated rollers 8 are hollow structures and the side walls are uniformly provided with a plurality of holes for air permeation. A placing rack 5 is arranged at the left end of the first vertical plate 7. The placing rack 5 is an L-shaped structure. The vertical rod of the placing rack 5 is fixed to the rear side edge of the fixed base 1 and is inclined upward to the left. The horizontal rod of the placing rack 5 faces forward and backward and is arranged at the upper end of the vertical rod. By arranging the vertical rod of the placing rack 5 to be inclined to the left and upward, the detection instrument can maximize the operation space above while keeping the occupied volume of the fixed base 1 small. The label paper can be pulled out stably. The connection between the placing rack 5 and the fixed base 1 is designed as a rotary connection. Angle locking devices are arranged at the connection part. When detection is needed, the placing rack 5 is rotated to the left so as to be unfolded, thereby facilitating the subsequent placement of the to-be-detected roll 6. However, when the device is not needed, the placing rack 5 can be rotated to the right and closed on the first vertical plate 7, thereby reducing the volume of the detection instrument and facilitating the storage of the detection instrument. The to-be-detected roll 6 with the label paper wound thereon can be sleeved on the placing rack 5 from front to back. At this time, the label paper can be pulled out from the to-be-detected roll 6 and passed through the gap between the upper and lower perforated rollers 8. The upper and lower perforated rollers 8 can clamp the label paper. In order to improve the clamping efficiency, a circle of rubber rings 16 can be arranged on the front and rear sides of the perforated rollers 8 to increase the friction. The lower perforated roller 8 rotates clockwise, and the upper perforated roller 8 rotates counterclockwise. At this time, the display layer 23 of the label paper is attached to the lower surface of the upper perforated roller 8, and the base layer 24 of the label paper is attached to the lower surface of the perforated roller 8. A suction head 9 that can generate negative pressure is arranged in the perforated roller 8. The suction force of the suction head 9 is transmitted to the label paper through the air permeation holes in the surface of the perforated roller 8, so that the perforated roller 8 can adsorb the label paper, thereby separating the display layer 23 and the base layer 24 of the label paper;

[0028] The winding mechanism 4 comprises a third vertical plate 32 fixedly arranged on the right side of the fixed base 1, the third vertical plate 32 is vertically arranged at the right end of the rear side edge of the fixed base 1, and a rotating shaft 33 is arranged in the middle of the third vertical plate 32 and arranged front-to-back, the winding roller 35 is sleeved on the outside of the rotating shaft 33 and rotates synchronously with the rotating shaft 33, after the display layer 23 and the base layer 24 of the label paper complete the light transmission detection, the display layer 23 and the base layer 24 are again adhered together, at this time, the label paper after being adhered is wound on the outside of the winding roller 35, the winding roller 35 can drive the movement of the label paper in the detector with the rotation of the rotating shaft 33, and the power for winding is provided.

[0029] In one case of the embodiment, the upper end of the first vertical plate 7 is rotationally connected with a rotating seat 17, the rotating seat 17 can rotate forward and backward relative to the first vertical plate 7, and the rear end of the upper porous roller 8 is rotationally connected with the side of the rotating seat 17, the porous roller 8 can rotate left and right relative to the rotating seat 17, thus when the rotating seat 17 rotates forward, the upper porous roller 8 can fall on the lower porous roller 8, and the label paper is pressed tightly by the action of gravity, and the limiting support 18 is arranged above the rear side of the first vertical plate 7, when it is needed to clamp the label paper, the upper porous roller 8 can be turned to the rear side, at this time the limiting support 18 can support the porous roller 8, at this time the two porous rollers 8 are separated, providing a larger space for the operator to process the label paper clamping.

[0030] In one case of the embodiment, the support wheel 48 is arranged directly below the lower porous roller 8, the support wheel 48 is rotationally connected with the upper surface of the fixed base 1, the support wheel 48 can support the lower porous roller 8, avoiding that the porous roller 8 is in the state of cantilever beam affecting normal rotation, the side of the suction head 9 adhering to the inner wall of the porous roller 8 is arranged as a curved surface, and in order to reduce the demand for negative pressure strength, only the arc surface corresponding to 90° central angle is arranged, thus the upper suction head 9 is rightward toward the position directly below, and the lower suction head 9 is rightward toward the position directly above, so that the position of the porous roller 8 contacting the label paper can generate negative pressure, but the surface of the porous roller 8 not contacting the label paper has no negative pressure, reducing the demand for negative pressure of the suction head 9, and in order to facilitate the turning of the porous roller 8, the fixed block 13 fixedly connected with the fixed base 1 is arranged on the left and right sides of the lower porous roller 8, the fixed block 13 is slidingly connected with the front and back arranged extension sliding rod 14, the front end of the extension sliding rod 14 is fixedly connected with the transverse moving seat 15, and the gripper is arranged on the front side of the transverse moving seat 15, through the gripper, the operator can conveniently pull the transverse moving seat 15 to move forward and backward, the transverse moving plate 11 is vertically arranged on the upper surface of the transverse moving seat 15, the fixed air pipe 10 is arranged on the upper and lower sides of the transverse moving plate 11, the rear end of the fixed air pipe 10 is in communication with the suction head 9, the three-way pipe 12 is arranged on the front side of the transverse moving plate 11, the front ends of the two fixed air pipes 10 are connected with the three-way pipe 12, and the external air source is connected with the three-way pipe 12, so that the two suction heads 9 can be connected with one air source, thus only one air pressure control device is needed, when the air source is opened, due to the arrangement of the three-way pipe 12, the upper and lower suction heads 9 can generate negative pressure at the same time, reducing the operation difficulty of the whole device, and also making it only need to provide one external air pipe to be connected with the three-way pipe 12 when installing the whole detector, reducing the installation difficulty of the whole detector, and making the air pressure control of the suction head 9 more convenient.

[0031] In one of the embodiments, the left end of the deflection plate 26 is fixedly connected to the rear end of the main shaft 31, 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 the front and rear limiting slide rods 28, and the limiting holes 29 are arranged above the second vertical plate 25. When the pull plate 27 is pulled upward, the limiting slide rods 28 are inserted into the limiting holes 29, and the rotating plate 19 is in the right and upward state, so that the display layer 23 can be better transferred from the left multi-hole roller 8 to the right winding roller 35.

[0032] In one of the embodiments, the clamping assembly 34 is arranged on the outer side of the rotating shaft 33. When the winding roller 35 is sleeved on the outer side of the rotating shaft 33, the clamping assembly 34 can tightly press the inner wall of the winding roller 35, so that the winding roller 35 is fixed on the outer side of the rotating shaft 33 and rotates synchronously with the rotating shaft 33. The pressing assembly 36 is arranged above the third vertical plate 32, and the pressing assembly 36 provides a pressing force to the winding roller 35, so that the label paper wound by the winding roller 35 can be more closely attached, and the display layer 23 and the base layer 24 that are reattached together are more closely attached. The driving motor 37 is arranged below the rear side of the third rotating shaft 33. The output shaft of the driving motor 37 is fixedly connected to the first bevel gear 38. The first bevel gear 38 is meshingly connected to the second bevel gear 39. The second bevel gear 39 is fixedly connected to the rear end of the rotating shaft 33. Therefore, the driving motor 37 can drive the rotating shaft 33 to rotate through gear transmission, thereby achieving the effect of rotating the winding roller 35.

[0033] In one of the embodiments, the clamping assembly 34 includes the sleeves 41 arranged on the front and rear sides of the rotating shaft 33. The rear sleeve 41 is fixedly connected to the rotating shaft 33, and the front sleeve 41 slides along the rotating shaft 33. The clamping springs 43 are arranged between the front and rear sleeves 41. The clamping springs 43 are sleeved on the outer side of the rotating shaft 33. The connecting plates 42 are rotatably connected to the outer side of the sleeves 41. The three connecting plates 42 are uniformly distributed on the outer side of the sleeves 41 along the center of the rotating shaft 33. The ends of the connecting plates 42 away from the sleeves 41 are rotatably connected to the clamping plates 44. Therefore, when the winding roller 35 is sleeved on the outer side of the clamping plates 44, the clamping springs 43 push the sleeves 41 away from each other, so that the clamping plates 44 tightly press the inner wall of the winding roller 35. When one of the clamping plates 44 tightly presses the inner wall of the winding roller 35, the clamping of the winding roller 35 is completed by the same clamping spring 43 due to the arrangement of the connecting plates 43 on the front and rear sides. At this time, the three clamping plates 44 are tightly attached to the outer side of the winding roller 35, so that the winding roller 35 is in a parallel state with the rotating shaft 33, thereby completing the clamping effect of the winding roller 35. The handles 40 are arranged on the front side of the front sleeve 41. The operator can pull the front sleeve 41 forward through the handles 40, so that the clamping plates 44 are close to each other, thereby facilitating the sleeving of the winding roller 35 on the outer side of the clamping plates 44.

[0034] In one case of the embodiment, the pressing assembly 36 comprises 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 a mounting frame 45, the mounting frame 45 is rotatably connected to a pressing roller 46, when the hanging plate 47 rotates to the front side, the pressing roller 46 can fall above the winding roller 35 under the action of gravity, the pressing roller 46 exerts pressure on the winding roller 35 through the gravity, and the pressing roller 46 is designed as a roller body externally sleeved with a rubber layer, so that when the pressing roller 46 falls outside the winding roller 35 wound with the label paper, the pressing roller 46 and the winding roller 35 have a large enough friction, so that the pressing roller 46 rotates synchronously with the winding roller 35, so that the pressing roller 46 only provides effective pressure and does not affect the winding of the label paper to the outside of the winding roller 35, when the hanging plate 47 rotates to the rear side, the hanging plate 47 rotates to the state of abutting against the upper end of the third vertical plate 32, at this time the mounting frame 45 is blocked to the rear side of the third vertical plate 32, at this time the pressing roller 46 is completely separated from the winding roller 35, which can facilitate the installation process of the winding roller 35.

[0035] In the implementation process of the embodiment, a controller is arranged on the upper surface of the fixed base 1, the controller controls the normal operation of the light measuring sensor 20, the light emitter 22, the driving motor 37 and the suction head 9, and the front end of the three-way connector 12 is connected with the air source, and the entire detector is connected with the power supply.

[0036] The label paper is installed, first, the pressing roller 46 is turned over to the rear side, so that the pressing roller 46 rotates to the rear side of the third vertical plate 32, the left hand of the operator pulls the handle 40 to the front side, the clamping plate 44 abuts against the outside of the rotating shaft 33, at this time the right hand of the operator presses the clamping plate 44, the left hand of the operator holds up the winding roller 35, the winding roller 35 is sleeved on the outside of the clamping plate 44 from front to back, the right hand of the operator is released, the winding roller 35 is sleeved on the middle part of the rotating shaft 33, the winding roller 35 is fixed, the measured winding drum 6 to be detected is taken from the front and is sleeved on the placing frame 5 from front to back, the transverse seat 15 is pulled to the front side, the suction head 9 moves to the front side of the multi-hole roller 8, the multi-hole roller 8 above is rotated to the upper side of the first vertical plate 7, at this time the free end of the label paper is pulled out, the label paper is placed on the multi-hole roller below, the label paper at the free end is manually torn, so that the display layer 23 and the base layer 24 are separated, the display layer 23 passes through the gap between the light measuring sensor 20 and the light emitter 22, the base layer 24 passes through below the second guide rod 30, and then the display layer 23 and the base layer 24 are abutted together and fixed on the outside of the winding roller 35.

[0037] The label paper is fixed, the forward side is turned over the pressing roller 46, the pressing roller 46 falls outside the fixed label paper winding roller 35, at this time the forward side is turned over the porous roller 8, the upper porous roller 8 is pressed on the upper side of the label paper, the horizontal moving seat 15 is pushed to the rear side, the suction head 9 moves to the inside of the porous roller 8, the pull plate 27 is pulled up, and the limiting slide rod 28 is inserted into the limiting hole 29, at this time the rotating plate 19 is inclined to the right upper side, at this time the display layer 23 and the base layer 24 of the label paper are separated, the display layer 23 is attached to the lower surface of the upper porous roller 8, the base layer 24 is attached to the upper surface of the lower porous roller 8, and the label paper completes the fixing process.

[0038] The detection process is started, the light sensor 20 and the light emitter 22 are started, and the related data of the light sensor 20 and the light emitter 22 are connected to the computer, data collection is carried out, the suction head 9 is first opened, the suction head 9 generates negative pressure, the porous roller 8 adsorbs the display layer 23 and the base layer 24 of the label paper, then the driving motor 37 is started, the driving motor 37 drives the winding roller 35 to rotate clockwise through the gear transmission, the label paper is wound in the winding roller 35, so the label paper is transferred from the outside of the to-be-detected winding roller 6 to the outside of the winding roller 35 from left to right, in the process of moving the label paper, the label paper is separated due to the adsorption of the porous roller 8, the display layer 23 passes through the position of the light sensor 20 and the light emitter 22 to carry out the light transmission detection process, and because the label paper is manually torn at the free end at the beginning, the second guide rod 30 pulls the base layer 24 downward, the winding roller 35 is above to wind the display layer 23, so the label paper that has been opened can be easily separated by the suction force of the porous roller 8, 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 light sensor 20 and the light emitter 22 relatively flat.

[0039] When the label paper completes the detection, the label paper that completes the detection needs to be taken out, and the entire detector needs to be arranged and fixed.
