Description

Technical Field

[0001] The present invention relates to the technical field of industrial instruments, and particularly to a small electric hand-held expandable low-power adjustable-speed labeling instrument and method. Background Art

[0002] A label paper labeling instrument is a label paper pasting machine widely used in industry and is widely applied in industrial sites. With the rapid development of the consumer market, the application of label paper labeling instruments in consumer goods is also increasing, especially in the process of pasting labels on fruits and small commodities, and the demand for small electric hand-held expandable low-power adjustable-speed labeling instruments is gradually emerging.

[0003] Patent document CN207312015U discloses a hand-held labeling instrument which needs to "pinch" by hand to eject labels, belonging to a mechanical labeling instrument. After using this mechanical labeling instrument for a long time, the human hand will ache. At the same time, this mechanical labeling instrument has disadvantages such as slow label ejection speed, small capacity for carrying label paper, and inability to expand to load label paper of different widths.

[0004] Compared with the patent document CN207312015U, another patent document CN212606411U discloses an electric handheld labeling instrument. It controls the sticking of label paper through an electric switch and has the advantage of semi - automation. However, this electric handheld labeling instrument has the following deficiencies: (1) Its storage wheel, feeding component, peeling board, pressing roller, and collecting wheel are all of a certain fixed length, which restricts the width of the label paper used within this fixed length, thus limiting the versatility of this handheld labeling instrument; (2) The battery it loads is not modularly designed, resulting in a cumbersome and time - consuming process of loading the batteries one by one. At the same time, when the battery runs out of power, the battery must be removed and placed on a battery charger for charging. This requires the user to specifically equip a charger for charging the batteries one by one for separation, resulting in many accessories and inconvenient use of this electric handheld labeling instrument. At the same time, it also cannot meet the user's need to continue using the labeling instrument while charging; (3) Different users of the labeling instrument have different requirements for the sticking speed of the label. For example, skilled users generally hope to stick the label faster to improve work efficiency. However, the faster the label is stuck, it is directly related to the rotation speed of the motor. The higher the rotation speed of the motor, the faster the label paper can come out, and thus it is possible for the user to stick the label faster. This requires the labeling instrument to be able to adjust the rotation speed of the motor. However, the handheld labeling instrument disclosed in the patent document CN212606411U does not have a motor speed regulation module and cannot achieve motor speed adjustment; (4) Since the electric labeling instrument is powered by a battery and the battery capacity is limited, low - power consumption design is required to make the use time of the labeling instrument longer under a single charge. However, the patent document CN212606411U does not consider this requirement and has not carried out relevant designs. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a small - sized electric handheld expandable low - power - consumption adjustable - speed labeling instrument and method. It is used to achieve the automatic sticking of label paper by hand; compared with traditional handheld labeling instruments, it has strong expandability, convenient battery disassembly and charging, adjustable speed for recycling label paper, low standby power consumption, various triggering methods, label face paper paper - out counting and other functions.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A small - sized electric handheld expandable low - power - consumption adjustable - speed labeling instrument, comprising a housing, a storage wheel, an automatic paper - stop sensor, a label paper peeling board, a label - pressing wheel, a collecting wheel, a paper - guiding column, a power switch, a rotating lever, a support rod, a lever support column, a battery module, a motor, a control circuit module, a paper - out induction module, a label paper baffle, and a slide rail;

[0008] On the outer wall of the housing, there are installed a storage wheel, an automatic paper stop sensor, a label paper peeling plate, a paper guiding column, a power switch, a rotating lever, a battery module, a motor, and a slide rail. Inside the housing, there are installed a lever support column and a control circuit module;

[0009] The storage wheel is used to load the roll of label paper;

[0010] The automatic paper stop sensor is movably connected to the slide rail through a positioning bolt. The automatic paper stop sensor is used to sense the change in the thickness of the label paper. When the thickness change exceeds the threshold, a trigger signal is generated to trigger the motor to stop rotating;

[0011] The label paper peeling plate is used to realize the peeling of the label face paper and the label backing paper;

[0012] The rotating lever is rotatably installed at the head of the housing through a lever support column. There is a handle at the tail of the housing, and the battery module is installed at the end of the handle;

[0013] The front end of the rotating lever is connected with the support rod, and the paper output induction module is installed at the end of the rotating lever. The support rod is used to support the label paper pressing wheel; the label paper pressing wheel is used to press the peeled label face paper onto the object to be pasted;

[0014] The rotating shaft of the motor is fixedly connected to the take-up wheel and drives the take-up wheel to rotate; the take-up wheel recovers the generated label backing paper by rotating;

[0015] The paper guiding column is used to guide the moving path of the label paper;

[0016] The power switch is electrically connected to the battery module and the control circuit module;

[0017] The control circuit module is electrically connected to the automatic paper stop sensor, the motor, and the paper output induction module;

[0018] The label paper baffle is arranged at one end of the storage wheel and is used to prevent the roll of label paper from slipping out of the storage wheel;

[0019] The paper output induction module uses a switch sensor or a distance sensor. When the paper output induction module uses a switch sensor, the switch sensor is installed at the end of the rotating lever, and the rotating lever rotates with the lever support column as the rotation axis; when the paper output induction module uses a distance sensor, the distance sensor is connected to the control circuit module through a wire, and the distance sensor is installed on the platform where the conveyor belt is located.

[0020] Further, the housing is composed of two detachable sub-housings that are snap-connected to each other. The housing is also provided with a motor speed regulator and a sensitivity regulator that are electrically connected to the control circuit module. The motor speed regulator is used to adjust the rotation speed of the motor, and the sensitivity regulator is used to adjust the sensing sensitivity of the automatic paper stop sensor.

[0021] Further, the control circuit module is composed of a microprocessing circuit and a motor drive circuit. When the output state of the paper feeding induction module changes, the microprocessor circuit drives the motor to start rotating through the motor drive circuit; at the same time, when the output state of the automatic paper stop sensor changes, the microprocessor circuit drives the motor to stop rotating through the motor drive circuit; when each label paper is finished, the control circuit module automatically sets the motor and the motor drive circuit to the sleep state to reduce the standby power consumption of the labeling machine.

[0022] Further, the housing is also provided with an indicator. The indicator includes a power indicator and a count indicator that are electrically connected to the control circuit module. The power indicator and the count indicator are integrally integrated in the indicator or separately provided. The power indicator is used to display the remaining power, and the count indicator is used to display the number or the remaining number of the peeled label face papers.

[0023] Further, the switch sensor includes, but is not limited to, a mechanical switch sensor, a leaf spring opening and closing switch sensor, a photoelectric switch sensor, a microswitch sensor, and a push-button switch sensor; when the switch sensor contacts the end of the rotating lever, a trigger signal is generated to the control circuit module, and the control circuit module controls the motor to start rotating; the sensing distance sensor is used to sense the change in the distance between the object to be labeled on the conveyor belt and the sensing distance sensor. When the distance change exceeds the threshold, the distance sensor outputs a trigger signal to the control circuit module, and the control circuit module controls the motor to start rotating.

[0024] Further, the paper guide posts include a first paper guide post, a second paper guide post, a third paper guide post, and a fourth paper guide post located between the material storage wheel and the label paper peeling plate.

[0025] Further, the empty ends of the material storage wheel, the paper guide posts, and the material collection wheel are respectively provided with expansion interfaces. By splicing the corresponding expansion posts of the material storage wheel, the paper guide posts, and the material collection wheel through the expansion interfaces, different widths of label papers can be adapted. Different widths of label papers can be adapted by replacing the label paper peeling plate and the label paper pressing wheel with different lengths.

[0026] Further, the end of the handle is detachably connected to the battery module. A groove that fits the shape of the battery module is provided in the cavity at the end of the handle of the housing, and a buckle for fixing the battery module is provided on the groove.

[0027] Further, the label paper is composed of a label base paper and a label face paper, and the automatic paper stop sensor is composed of a light emission module and a light receiving module; when the part of the label base paper with the label face paper attached is between the light emission module and the light receiving module, the automatic paper stop sensor outputs state P1. On the other hand, when only the part of the label base paper is between the light emission module and the light receiving module, the automatic paper stop sensor outputs state P2, and state P1 is different from P2; when the control circuit module detects each time that the state output by the automatic paper stop sensor changes from P1 to P2, it means that a label face paper has passed through the automatic paper stop sensor at the current moment. The control circuit module will stop the rotation of the motor through a control signal, stop the feeding of the feeding wheel at the same time, and count the number of label face papers discharged through an indicator at the same time.

[0028] The present invention also provides a method for using a labeling machine, based on the above-mentioned high-speed labeling machine, including:

[0029] S1. Load the battery module in the handle;

[0030] S2. Place the roll of label paper on the storage wheel;

[0031] S3. Install the label paper baffle on the storage wheel to prevent the label paper from slipping off the storage wheel;

[0032] S4. Draw out the label paper from the roll of label paper, and then load the drawn label paper on the labeling machine in the following order: the paper guide column, the gap between the automatic paper stop sensors, the paper guide column, the paper guide column, the upper surface of the label paper peeling board, the lower surface of the label paper peeling board, the paper guide column, the feeding wheel;

[0033] S5. Adjust the speed of the motor to a speed recognized by the user of the labeling machine through the motor speed regulator;

[0034] S6. Adjust the sensing sensitivity of the automatic paper stop sensor through the sensitivity regulator. The adjustment process is as follows: when the label face paper passes through the automatic paper stop sensor, the motor does not stop rotating, and when the subsequent label base paper of the label face paper passes through the automatic paper stop sensor, the motor immediately stops rotating, then the sensing sensitivity adjustment of the automatic paper stop sensor is completed;

[0035] S7. When the user of the labeling machine places the label paper pressing wheel on the object to be labeled so that the label paper pressing wheel is lifted from below to above, based on the lever principle, the tail contact of the rotating lever displaces from above to below. At this time, the tail contact will trigger the paper output induction module to output a trigger signal to the control circuit module, and the control circuit module drives the motor to start rotating and feed materials;

[0036] When the part of the label backing paper with the label face paper attached is between the light emitting module and the light receiving module of the automatic paper stop sensor, the automatic paper stop sensor outputs state P1. Immediately afterwards, when only the part of the label backing paper is between the light emitting module and the light receiving module of the automatic paper stop sensor, the automatic paper stop sensor outputs state P2; each time the control circuit module detects that the state output by the automatic paper stop sensor changes from P1 to P2, the control circuit module drives the motor to stop rotating, that is, stops receiving materials; at the same time, the number of sheets of the label face paper is counted through an indicator.

[0037] S8. The labeler user replaces the battery module at any time according to the remaining power displayed in the indicator.

[0038] S9. After the labeler is used up, close the power switch to turn off the labeler.

[0039] Compared with the prior art, the beneficial effects brought by the technical solution of the present invention are:

[0040] 1. Strong scalability: It can replace or splice storage wheels, guide components, peeling plates, pressure sticking rollers, receiving wheels, etc. with appropriate lengths according to the width of the label paper used, thereby greatly enhancing the versatility of the handheld labeler.

[0041] 2. Convenient battery disassembly, charging: Using a modular battery as the power supply, it is convenient for disassembly, replacement, and charging.

[0042] 3. The speed of the labeler for recycling label paper can be adjusted: Through the design of the motor speed control circuit, the speed of the motor is adjusted by an adjustable rheostat, thereby further realizing the flexible adjustment of the paper output speed of the label paper.

[0043] 4. Low standby power consumption: The motor and the motor drive chip are the main power consumption sources of the entire system. Therefore, by adopting the method of automatically putting the motor and the motor drive chip into the sleep state after each label paper is ejected, the standby power consumption of the entire labeler is greatly reduced, realizing low-power design.

[0044] 5. The triggering method of the paper output induction module can be selected as needed, and the triggering method can be various.

[0045] 6. It has the function of counting the paper output of the label face paper and can count the label face paper passing through the automatic paper stop sensor A3. Description of the Drawings

[0074] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0075] SeeFigures 1 to 4 , the small electric hand-held expandable low-power adjustable-speed labeling instrument provided in this embodiment includes a housing A1, a material storage wheel A2, an automatic paper stop sensor A3, a label paper peeling plate A4, a label paper pressing wheel A5, a material collection wheel A6, paper guide columns A7 to A10, a power switch A11, a rotating lever A12, a support rod A13, a lever support column A14, a motor speed adjustment rheostat A15, a sensitivity adjustment rheostat A16, a battery module A17, a power indicator A18, a counting indicator A19, a motor A20, a control circuit module A21, a paper output induction module A22, and a label paper baffle D1;

[0076] The housing A1 is composed of a sub-housing Aa1 and a sub-housing Aa2; a cavity is formed between the sub-housing Aa1 and the sub-housing Aa2. On the outer wall of the sub-housing Aa1, a material storage wheel A2, an automatic paper stop sensor A3, a label paper peeling plate A4, a material collection wheel A6, paper guide columns A7 to A10, a power switch A11, a rotating lever A12, a battery module A17, a power indicator A18, a counting indicator A19, a motor A20, and a slide rail D2 are installed; inside the cavity formed between the sub-housing Aa1 and the sub-housing Aa2, a lever support column A14, a control circuit module A21, and a paper output induction module A22 are installed.

[0077] The material storage wheel A2 is installed in the upper right of the side wall of the sub-housing Aa1 for loading a roll of label paper; the automatic paper stop sensor A3 is installed above the side wall 6 of the sub-housing Aa1 for sensing the change in the thickness of the label paper. When the thickness change exceeds the threshold, a trigger signal for controlling the motor to stop rotating is generated; the label paper peeling plate A4 is installed in the front of the side wall of the sub-housing Aa1 for realizing the peeling of the label face paper and the label base paper; the label paper pressing wheel A5 is installed at the front end of the housing A1 through the rotating lever A12 for pressing the peeled label face paper on the object to be labeled; the material collection wheel A6 is installed below the middle of the sub-housing Aa1 for recycling the generated label base paper by rotation; the paper guide columns A7, A8, and A9 are installed on the side wall of the sub-housing Aa1 between the material storage wheel A2 and the label paper peeling plate A4 from top to bottom in sequence, and A10 is installed on the lower sub-housing Aa1 between the paper guide columns A8 and A9 for guiding the moving path of the label paper.

[0078] The battery module A17 is used to supply power to the control circuit module A21; the power switch A11 is installed on the upper surface of the sub-housing Aa1 for controlling the battery module A17 to supply power to the control circuit module A21; when the power switch A11 is closed, the battery module A17 supplies power to the control circuit module A21, and when the power switch A11 is opened, the battery module A17 does not supply power to the control circuit module A21.

[0079] The front end of the rotating lever A12 is fixed to the support rod A13, and the middle is rotatably connected to the lever support column A14; the support rod A13 is used to support the label pressing wheel A5; the lever support column A14 is installed on the inner wall of the sub-housing Aa1 as the fulcrum of the rotating lever A12.

[0080] Openings are made on the side wall of the sub-housing Aa1, and a motor speed regulating rheostat A15 and a sensitivity regulating rheostat A16 are respectively installed. In this embodiment, the sensitivity regulating rheostat A16 can adopt a 3362P precision adjustable resistor or a 3296W precision adjustable resistor. The motor speed regulating rheostat A15 is used to regulate the rotation speed of the motor; the sensitivity regulating rheostat A16 is used to regulate the sensing sensitivity of the automatic paper stop sensor A3.

[0081] In this implementation, the power indicator A18 and the counting indicator A19 are separately set. Installation holes for installing the power indicator A18 and the counting indicator A19 are opened at the top of the sub-housing Aa1. The power indicator A18 is used to indicate the remaining power of the battery module A17; the counting indicator A19 is used to indicate the number of peeled label face papers.

[0082] The rotating shaft of the motor A20 is fixedly connected to the material receiving wheel A6 and drives the material receiving wheel A6 to rotate.

[0083] The control circuit module A21 is composed of a microprocessing circuit A21-1 and a motor drive circuit A21-2, and the control circuit module A21 is respectively electrically connected to the power indicator A18, the sensitivity regulating rheostat A16, the motor speed regulating rheostat A15, the automatic paper stop sensor A3, the paper output induction module A22, the motor A20, the power indicator A18, the counting indicator A19, the power switch A11 and the paper output induction module A22; the battery module A17 is electrically connected to the power switch A11, as Figure 4 shown;

[0084] When the output state of the paper output induction module A22 changes, the microprocessor circuit A21-1 drives the motor A20 to start rotating through the motor drive circuit A21-2; at the same time, when the output state of the automatic paper stop sensor A3 changes, the microprocessor circuit A21-1 drives the motor A20 to stop rotating through the motor drive circuit A21-2;

[0085] The paper output induction module A22 is placed near the end of the rotating lever A12. When the rotating lever A12 rotates around the lever support column A14, the end of the rotating lever A12 triggers the paper output induction module A22 to output a trigger signal for controlling the motor to start rotating; a handle A24 is provided at the tail of the housing A1, and the battery module A17 is detachably installed at the end of the handle A24.

[0086] The label paper baffle D1 is used to prevent the rolled label paper K1 from slipping off the storage wheel A2; the automatic paper stop sensor A is movably connected to the slide rail D2 through a positioning bolt, and the slide rail D2 is used for the automatic paper stop sensor A3 to slide and be fixed on it.

[0087] Preferably, the first feature of this embodiment is strong scalability. Specifically:

[0088] In this embodiment, the label applicator can change the widths of the storage wheel A2, the paper guide columns A7 to A10, and the take-up wheel A6 by means of splicing and expansion according to the width of the label paper actually required. At the same time, the widths of the label paper peeling plate A4 and the label paper pressing wheel A5 are changed by replacement to match the width of the label paper;

[0089] More specifically, the splicing and expansion method for changing the width of the storage wheel A2 is as follows: The right-end boss of the storage wheel extension column A2-1 is spliced with the left-end groove of the storage wheel A2 by an interference fit method (as Figure 5-1 shown), so as to realize the expansion of the width of the storage wheel A2. The result after splicing is as Figure 5-2 shown. At the same time, the width of the storage wheel extension column A2-1 can be selected according to actual needs;

[0090] The splicing and expansion method for changing the widths of the paper guide columns A7 to A10 is as follows: The right-end bosses of the paper guide column extension columns A7-1, A8-1, A9-1, and A10-1 are spliced with the left-end grooves of the paper guide columns A7 to A10 by an interference fit method (as Figure 6-1 shown), so as to realize the expansion of the widths of the paper guide columns A7 to A10. The result after splicing is as Figure 6-2 shown. At the same time, the widths of the paper guide column extension columns A7-1, A8-1, A9-1, and A10-1 can be selected according to actual needs;

[0091] The splicing and expansion method for changing the width of the take-up wheel A6 is as follows: The right-end boss of the take-up wheel extension column A6-1 is spliced with the left-end groove of the take-up wheel A6 by an interference fit method (as Figure 7-1 shown), so as to realize the expansion of the width of the take-up wheel A6. The result after splicing is as Figure 7-2 shown. At the same time, the width of the take-up wheel extension column A6-1 can be selected according to actual needs;

[0092] The method for expanding the width of the label paper pressing wheel is as follows (as Figure 8 shown): After removing the screw A23, the support rod A13 and the label paper pressing wheel A5 can be taken out, and then the wider support rod A13-2 and the wider label paper pressing wheel A5-2 are fixed on the rotating lever A12 by the screw A23, and the expansion of the width of the label paper pressing wheel can be completed;

[0093] The method for expanding the width of the label paper peeling board is as follows (as Figure 9 shown): After removing the screws in the screw holes Aa2-1 and Aa2-2, the label paper peeling board A4 can be taken out from the sub-housing Aa1. Then, fix the label paper peeling board A4-1 with a larger width in the screw holes Aa2-1 and Aa2-2 through screws, and the expansion of the width of the label paper peeling board can be completed;

[0094] Preferably, the second feature of this embodiment is that the battery can be disassembled, assembled and charged conveniently. Specifically:

[0095] The battery module A17 is a complete modular battery, rather than separate single batteries. A groove A25 and a buckle A26 matching the outer shape of the battery module A17 are designed at the handle A24 of the small electric handheld expandable low-power adjustable-speed labeling machine. The battery module A17 can be installed in the handle A24 along the Figure 10 arrow direction in the figure and clamped by the buckle A26. At the same time, when the battery of the battery module A17 is exhausted, the battery module A17 can be taken out from the handle A24, replaced with other battery modules of the same model, and the removed battery module A17 can be charged. This modular disassembly and assembly design of the battery can bring the following advantages: Only by alternately using and charging two battery modules, the uninterrupted power supply of the small electric handheld expandable low-power adjustable-speed labeling machine can be realized, which is convenient for users to use continuously for a long time;

[0096] Preferably, the third feature of this embodiment is that the speed of the label paper recovery of the labeling machine can be adjusted:

[0097] By changing the size of the motor speed regulating rheostat A15 to control the change of the rotation speed of the motor A20. Since the rotating shaft of the motor A20 is fixedly connected to the material receiving wheel A6, the rotation speed of the material receiving wheel A6 also changes with the change of the rotation speed of the motor A20. With the change of the rotation speed of the material receiving wheel A6, the adjustment of the speed of the label paper recovery of the labeling machine can be realized. Further, an embodiment of the adjustment of the speed of the label paper recovery of the labeling machine is given here, but the actual implementation process is not limited to this embodiment; as Figure 11 shown, the motor speed regulating rheostat A15 can realize the motor speed adjustment according to the following principle (as Figure 11 shown): First, Figure 11The resistor R2 therein is the motor speed regulating rheostat A15 mentioned above. The resistor R2 is connected in series with another resistor R1 and connected to a power supply with an output voltage of VCC. The voltage V1 between the resistors R1 and R2 is output to the signal conditioning circuit A21-3, and the signal conditioning circuit A21-3 is used to amplify, filter, and transform the voltage V1 signal. Further, the voltage signal output from the signal conditioning circuit A21-3 is transmitted to the analog-to-digital converter A21-4. The analog-to-digital converter A21-4 converts the input analog voltage signal into a digital voltage signal V2 and then transmits it to the microprocessor circuit A21-1. The microprocessor circuit A21-1 adjusts parameters such as the frequency and duty cycle of the output PWM (Pulse Width Modulation) signal according to the magnitude of the voltage signal V2. By changing the PWM signal parameters and through the motor drive circuit A21-2, the rotation speed of the motor A20 is adjusted.

[0098] Preferably, the fourth feature of this embodiment is low standby power consumption:

[0099] The motor A20 and the motor drive circuit A21-2 are the main power-consuming parts of the whole system. Therefore, when each label paper is ejected, the motor A20 and the motor drive circuit A21-2 are automatically set to the sleep state, which can greatly reduce the standby power consumption of the whole labeling machine, thus realizing the low-power design. Further, the low standby power consumption of the present invention is achieved as follows: Once the motor A20 stops rotating, the microprocessor circuit A21-1 controls the motor drive circuit A21-2 to enter the sleep state to reduce the energy consumption of the motor drive circuit A21-2 and achieve the goal of low standby power consumption.

[0100] Preferably, the fifth feature of this embodiment is that the triggering mode of the paper ejection induction module can be selected as needed, and the triggering modes can be various:

[0101] The first triggering mode of the paper ejection induction module A22 is as Figure 12 shown. When the user of the labeling machine places the label pressing wheel A5 on the object to be labeled so that the label pressing wheel A5 is lifted from below upwards, based on the lever principle, the tail contact A12-2 of the rotating lever A12 will displace from above downwards. At this time, the tail contact A12-2 will trigger the switch sensor A22-1 to output the state M1. On the other hand, when the label pressing wheel A5 falls from above downwards, based on the lever principle, the tail contact A12-2 of the rotating lever A12 will displace from below upwards. At this time, the tail contact A12-2 will trigger the switch sensor A22-1 to output the state M2. Further, when the microprocessor circuit A21-1 (see Figure 4)When it is detected that the state output by the paper output induction module A22 changes from M2 to M1, the microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to rotate for material collection; further, the switch sensor A22-1 can be a mechanical switch sensor, a leaf spring opening and closing switch sensor, a micro switch sensor, a button switch sensor, etc., or it can be an opto-switch sensor;

[0102] Further, when the switch sensor A22-1 is an opto-switch sensor, the front view of the triggering structure of the paper output induction module is as Figure 13 shown. The switch sensor A22-1 is composed of a light emission module A22-2 and a light reception module A22-3. When the user of the labeling machine places the label pressing wheel A5 on the object to be labeled so that the label pressing wheel A5 is lifted from below to above, based on the lever principle, the tail baffle A12-3 of the rotating lever A12 will displace from above to below. At this time, the tail baffle A12-3 will block the light emitted from the light emission module A22-2 to the light reception module A22-3. At this time, the paper output induction module A22 outputs the state E1. On the other hand, when the light between the light emission module A22-2 and the light reception module A22-3 is not blocked, the paper output induction module A22 outputs the state E2; further, when the microprocessor circuit A21-1 (see Figure 4 ) detects that the state output by the paper output induction module A22 changes from M1 to M2, the microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to rotate for material collection;

[0103] Further, the second triggering method of the paper output induction module A22 is as Figure 14 shown. The paper output induction module A22 is composed of a distance sensor B5. The paper output induction module A22 is connected to the control circuit module A21 through a long wire B4. The paper output induction module A22 can be installed on the housing A1 or on the platform where the conveyor belt B3 is located; further, the objects B1, B2 to be labeled have a certain height and move on the conveyor belt B3. When the object B1 or B2 to be labeled is at a distance L1 from the distance sensor B5, the paper output induction module A22 outputs the state Q1. When the object B1 or B2 to be labeled is at a distance L2 from the distance sensor B5, the paper output induction module A22 outputs the state Q2; further, when the microprocessor circuit A21-1 (see Figure 4 ) detects that the state output by the paper output induction module A22 changes from Q1 to Q2 (or Q2 to Q1), the microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to rotate for material collection;

[0104] Further, the triggering method of the paper output induction module A22 can also be other methods. As long as the output state of the paper output induction module A22 changes in other methods, different states output by the paper output induction module A22 can be transmitted to the microprocessor circuit A21-1 (see Figure 4 ), the microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to rotate or stop, thereby completing the material collection or stopping of the material collection of the material collection wheel A6;

[0105] Preferably, the sixth feature of this embodiment is that it has a function of counting the output of the label face paper, which can count the label face paper passing through the automatic paper stop sensor A3:

[0106] The label paper K1 is composed of a label base paper K1-1 and a label face paper K1-2, as Figure 15 shown; the automatic paper stop sensor A3 is composed of a light emission module A3-1 and a light reception module A3-2; further, when the part of the label base paper K1-1 attached with the label face paper K1-2 is between the light emission module A3-1 and the light reception module A3-2, the automatic paper stop sensor A3 outputs a state P1. On the other hand, when only the part of the label base paper K1-1 is between the light emission module A3-1 and the light reception module A3-2, the automatic paper stop sensor A3 outputs a state P2; since the thickness of the part of the label base paper K1-1 attached with the label face paper K1-2 is different from the thickness of only the part of the label base paper K1-1, the two states P1 and P2 output by the automatic paper stop sensor A3 are also different; when the control circuit module A21 detects each time that the state output by the automatic paper stop sensor A3 changes from P1 to P2, it means that at this time, a label face paper K1-2 has passed through the automatic paper stop sensor A3. At this time, the control circuit module A21 will stop the rotation of the motor A20 through a control signal, that is, stop the material collection of the material collection wheel A6. At the same time, the display quantity of the counting indicator A19 is increased by 1 or decreased by 1 to realize the function of counting the output of the label face paper, as Figure 16 shown;

[0107] Specifically, the function of counting the output of the label face paper of the counting indicator A19 is not an essential function, and whether this function is available can be selected according to actual needs; when this function is not required, the counting indicator A19 can be removed;

[0108] To make the invention content, principle and working process of this application clearer, the following further takes the usage method of the above labeler as a specific embodiment:

[0109] The first step: Load the battery module A17 into the handle A24;

[0110] The second step: Place the roll of label paper K1 on the storage wheel A2;

[0111] Step 3: Install the label paper baffle D1 on the material storage wheel A2 to prevent the label paper K1 from slipping off the material storage wheel A2;

[0112] Step 4: Draw out a certain length of label paper from the roll of label paper K1, and then load the drawn label paper onto the labeling machine in the following order (as Figure 15 shown): the paper guide column A7 → the gap between the automatic paper stop sensor A3 (that is, between the light emitting module A3-1 and the light receiving module A3-2) → the paper guide column A8 → the paper guide column A9 → the upper surface of the label paper peeling plate A4 → the lower surface of the label paper peeling plate A4 → the paper guide column A10 → the material receiving wheel A6;

[0113] Step 5: Turn on the power switch A11;

[0114] Step 6: Adjust the speed of the motor A20 (that is, the material receiving wheel A6) to the speed recognized by the labeling machine user through the motor speed regulating rheostat A15;

[0115] Step 7: Adjust the sensing sensitivity of the automatic paper stop sensor A3 through the sensitivity regulating rheostat A16. The adjustment process is as follows: when the label face paper K1-2 passes through the automatic paper stop sensor A3, the motor A20 (that is, the material receiving wheel A6) does not stop rotating, and when the subsequent label base paper K1-1 of the label face paper K1-2 passes through the automatic paper stop sensor A3, the motor A20 (that is, the material receiving wheel A6) immediately stops rotating, which indicates that the sensing sensitivity adjustment of the automatic paper stop sensor A3 is completed;

[0116] Step 8: The labeling machine can start normal use: when the user of the labeling machine places the label paper pressing wheel A5 on the object to be labeled so that the label paper pressing wheel A5 is lifted from the bottom to the top, based on the lever principle, the tail contact A12-2 of the rotating lever A12 will displace from the top to the bottom. At this time, the tail contact A12-2 will trigger the switch sensor A22-1 to output the state M1. At this time, the microprocessor circuit A21-1 (see Figure 4)The state output by the detected paper output induction module A22 is changed from M2 to M1. The microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to start rotating for material collection. Further, when the part of the label backing paper K1-1 with the label face paper K1-2 attached thereto is between the light emission module A3-1 and the light receiving module A3-2, the automatic paper stop sensor A3 outputs the state P1. Immediately afterwards, when only the part of the label backing paper K1-1 is between the light emission module A3-1 and the light receiving module A3-2, the automatic paper stop sensor A3 outputs the state P2. When the control circuit module A21 detects each time that the state output by the automatic paper stop sensor A3 changes from P1 to P2, the microprocessor circuit A21-1 controls the motor drive circuit A21-2, and further drives the motor A20 to stop rotating, that is, to stop material collection. If the label applicator is designed with a function of counting the output of the label face paper, at this time, the displayed quantity of the counting indicator A19 will be increased or decreased by 1 to achieve the counting of the output of the label face paper;

[0117] Step 9: When the power indicator A18 shows low power, it can prompt the user of the label applicator to replace the battery module A17;

[0118] Step 10: When the label applicator is used up, close the power switch A11 to turn off the label applicator.
