Description

Technical Field

[0001] The invention belongs to the field of automatic control systems, and in particular relates to an intelligent material inlet and outlet control system for printing wine bottle decals. Background Art

[0002] In the process of producing wine bottles, it is necessary to pre-print the decal paper of the wine bottle, and then paste the decal paper on the surface of the wine bottle. In the printing process, the decal paper tape can be printed in batches by a printing device. According to an intelligent printing device proposed in patent application publication number: CN111070893A, the invention relates to the field of printing technology and discloses an intelligent printing device, including a printing body and a support frame fixedly connected directly above the printing body, a paper filling device is fixedly connected inside the printing body, a transverse rod is fixedly connected to the bottom of the front side of the paper filling device, an inclined plate is movably sleeved at the bottom of the inner cavity of the paper filling device, the bottom end of the inclined plate passes through the paper filling device and is movably connected to the outer surface of the transverse rod, the outer surface of the inclined plate is movably connected to the inside of the paper filling device, and the left side of the inner cavity of the paper filling device is fixedly connected to the right side of the inclined plate through an anti-adhesion device. The intelligent printing device slowly rotates the tilting plate 30 degrees clockwise, causing the adjacent printing papers in the paper filling device to shift to the right by the same distance, thereby avoiding paper jams caused by the printing papers sticking to each other during the printing process, thereby improving the smoothness of the printing equipment in printing paper.

[0003] However, when the printing equipment in the prior art is in use, it is necessary to supply decal paper tape (feed) into the interior of the printer. During the movement of the decal paper tape inside the printer, the motor drives the rotating frame to reel in (discharge) the printed decal paper tape, and it cannot be tightly wound during the reeling process. The main reason is that during the reeling process, if there is a slight deviation (or the printed pattern causes a slight change in the thickness of part of the printed paper, and if periodic superposition occurs during the reeling process, it will further magnify the imbalance on the reel), it will cause the diameter of one side of the reel to become larger and larger. If the reeling continues, the surface of the decal paper will be easily damaged, affecting the product quality. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent material inlet and outlet control system for printing wine bottle decals, which solves the problem that the surface of the decal is easily damaged when the existing printed paper tape is rolled up, thereby affecting product quality.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an intelligent control system for feeding and discharging of wine bottle decals, comprising a base and a control module, wherein a printer is fixedly connected to the upper end of the base, a printing cover is hinged to the upper end of the printer, an auxiliary tensioning mechanism is arranged on the base, a fixing frame is arranged on both sides of the upper end and the left and right sides of the base, a rotating frame is installed inside a bracket on a side of the fixing frame away from the base through a bearing, a quick replacement mechanism is arranged on the outer side of the rotating frame, a decal tape is wound around the outer side of the rotating frame through a round tube, a supporting roller 1 is installed inside the upper end of the fixing frame through a bearing, a supporting roller 2 is installed on the lower part of the inner wall of the fixing frame through a bearing, a motor is fixedly installed on the back of the fixing frame at one end of the base, and the output shaft of the motor is fixedly connected to the rotating frame;

[0006] The fixing frame is rotatably connected to the upper surface of the base, and the upper surface of the base is provided with a mounting countersunk hole, and the mounting countersunk hole is provided with an electric drive unit for driving the fixing frame to rotate on the upper surface of the base;

[0007] Two first pressure detection units are respectively provided at both ends of the support roller 1, two second pressure detection units are respectively provided at both ends of the support roller 2, and a first Hall unit and a second Hall unit are respectively provided in the support roller 1 and the support roller 2;

[0008] The two first pressure detection units are used to collect pressure information on both ends of the support roller 1, and distinguish the pressure information into first left pressure information and first right pressure information; the two second pressure detection units are used to collect pressure information on both ends of the support roller 2, and distinguish the pressure information into second left pressure information and second right pressure information; the first Hall unit is used to collect first speed information of the support roller 1; the second Hall unit is used to collect second speed information of the support roller 2;

[0009] The motor, the electric drive unit, the two first pressure detection units, the two second pressure detection units, the first Hall unit and the second Hall unit are respectively connected to the control module signal;

[0010] The control module is used to receive first left pressure information, first right pressure information, second left pressure information, second right pressure information, first speed information and second speed information; the control module is also used to generate an angle adjustment instruction when the deviation value of the second left pressure information and the second right pressure information exceeds a preset value, the angle adjustment instruction includes a rotation direction, and send the angle adjustment instruction to the electric drive unit, the electric drive unit is used to adjust the relative angle between the fixed frame and the base after receiving the angle adjustment instruction; the control module is also used to generate a deceleration instruction and send it to the motor when either the first left pressure information or the first right pressure information exceeds a preset threshold value, and the motor reduces the rotation speed after receiving the deceleration instruction ; The control module is also used to generate a stop command after either the first left pressure information or the first right pressure information is lower than a preset warning value, and the motor stops rotating after receiving the stop command; the control module is also used to generate a pre-alarm message after the change speed of either the first left pressure information or the first right pressure information exceeds a preset value. At this time, if the change speeds of the second left pressure information and the second right pressure information do not exceed the preset value, and the deviation value of the first speed information and the second speed information does not exceed the preset range, the pre-alarm message is released; if the change speeds of the second left pressure information and the second right pressure information exceed the preset value, or the deviation value of the first speed information and the second speed information exceeds the preset range, an alarm message is generated.

[0011] Principle and effect of the invention: The core principle of the invention is to precisely control the feeding and discharging of wine bottle decals during printing through an intelligent control system to ensure the stability and quality of the decal tape during printing and winding. The system realizes real-time monitoring and adjustment of the tension, position and speed of the decal tape through the coordinated work of multiple sensors and control units.

[0012] The auxiliary tensioning mechanism can apply appropriate tension to the decal tape to ensure its flatness and stability during the printing process. The rotating frame is used to reel in the decal tape after printing, while the quick change mechanism facilitates the rapid replacement of the tape during the printing process, improving production efficiency.

[0013] Support roller 1 and support roller 2 are respectively installed at the upper end of the fixed frame and the lower part of the inner wall (the two form a certain angle, which can improve the accuracy of data collection of the detection object). The first and second pressure detection units collect pressure information at both ends to monitor the tension of the paper tape. The first Hall unit and the second Hall unit collect the rotation speed information of support roller 1 and support roller 2 respectively, which is used to monitor the moving speed of the paper tape.

[0014] The electric drive unit is used to drive the fixed frame to rotate on the upper surface of the base to adjust the winding angle of the paper tape to ensure the uniformity of the winding. The control module receives information from each detection unit and generates corresponding control instructions according to preset parameters and algorithms, such as angle adjustment instructions, deceleration instructions, stop instructions and alarm information.

[0015] Angle adjustment instruction: When the deviation value of the second left pressure information and the second right pressure information exceeds the preset value, the control module will generate an angle adjustment instruction. This instruction will instruct the electric drive unit to adjust the relative angle between the fixed frame and the base to correct the deviation or unevenness that may occur during the winding process of the decal paper tape. Through this adjustment, it can ensure that the decal paper tape is tightly and evenly wound on the rotating frame, avoiding paper tape damage or product quality problems caused by uneven winding.

[0016] Deceleration instruction: When either the first left pressure information or the first right pressure information exceeds a preset threshold, the control module generates a deceleration instruction and sends it to the motor. This instruction causes the motor to reduce its rotation speed, thereby reducing the feed speed of the decal tape. This deceleration can prevent excessive tape tension caused by excessive feed speed, thereby avoiding possible tape breakage or printing quality problems.

[0017] Stop command: When either the first left pressure information or the first right pressure information is lower than the preset warning value, the control module will generate a stop command. This command will stop the motor to prevent further damage to the tape or equipment. This stop operation is a protection mechanism to ensure that when a potential problem is detected, the system can respond in time to avoid further losses.

[0018] Pre-alarm information and alarm information, when the change speed of either the first left pressure information or the first right pressure information exceeds the preset value, the control module will generate a pre-alarm information. This is an early warning mechanism used to remind operators of possible problems so that they can be checked and adjusted in time. If the change speed of the second left pressure information and the second right pressure information does not exceed the preset value at this time, and the deviation value of the first speed information and the second speed information does not exceed the preset range, the control module will release the pre-alarm information and resume normal operation. It can avoid false alarms and improve the accuracy of alarms. If the change speed of either the second left pressure information and the second right pressure information exceeds the preset value, or the deviation value of the first speed information and the second speed information exceeds the preset range, the control module will generate an alarm message. This is an indication of an emergency situation, requiring the operator to take immediate action, such as stopping the equipment operation, checking and solving the problem that caused the alarm. This alarm mechanism is an important means to ensure equipment and production safety.

[0019] By precisely controlling the tension and position of the decal tape, the deviation in the printing process is reduced, and the accuracy and quality of the printed pattern are improved. The intelligent control system can monitor the winding of the tape in real time, and avoid damage to the tape due to uneven winding by adjusting the angle of the fixing frame and the speed of the motor.

[0020] The application of quick change mechanism and electric drive unit enables the rapid replacement of paper tape and adjustment of winding angle during printing, which reduces downtime and improves production efficiency. The system can automatically monitor and adjust key parameters in the printing process, reducing manual intervention and operating difficulty. At the same time, through the pre-alarm and alarm mechanism, potential problems can be discovered and handled in advance. The control system can adjust the control strategy according to different types of decal tapes and printing requirements, and has good flexibility and adaptability.

[0021] In summary, the present invention not only improves the quality and efficiency of wine bottle decal printing through the intelligent inlet and outlet material control system, but also reduces manual intervention and improves the automation level of production through real-time monitoring and automatic adjustment, thereby avoiding the problem of damaging the decal surface and affecting product quality.

[0024] Furthermore, the roller frame 1 is slidably connected to the fixed frame, the adjustment bar is slidably connected to the fixed frame, the screw rod is connected to the adjustment bar via a bearing, one end of the spring 1 is fixedly connected to the roller frame 1, and the other end of the spring 1 is fixedly connected to the adjustment bar, and the spring 1 can support the roller frame 1 through elastic force.

[0025] Furthermore, one end of the second spring is fixedly connected to the fixing pin, and the other end of the second spring is fixedly connected to the second roller frame, and both the first and second tensioning rollers are in contact with the decal paper tape, and the second spring can support the second roller frame through elastic force.

[0026] Furthermore, the auxiliary frame is slidably connected to an upper frame inside, a spring three is arranged on the outside of the sliding rod of the upper frame, one end of the spring three is fixedly connected to the auxiliary frame, and the other end of the spring three is fixedly connected to the upper frame, an arc rubber block is fixedly connected to the upper end of the upper frame, a rubber ring is rotatably connected to the inside of the arc groove of the arc rubber block, and the rubber ring is fixedly connected to the rotating frame, and the spring three can push the arc rubber block against the outside of the rubber ring through elastic force to increase the resistance between the rubber ring and the arc rubber block.

[0027] Furthermore, the quick-change mechanism includes a limit frame, the outer side of the rotating frame is slidably connected to the limit frame, the limit frame is in contact with the decal paper tape, the inner side of the limit frame is slidably connected to a moving rod, one end of the moving rod close to the rotating frame is fixedly connected to a limiting column, a spring four is provided on the outer side of the moving rod, and one end of the moving rod away from the limiting column is fixedly connected to a pull ring, the pull ring is slidably connected to the limit frame, and the limit frame can limit the decal paper tape.

[0028] Furthermore, one end of the spring four is fixedly connected to the limit column, the limit column is slidably connected to the rotating frame and the limit frame, the pull ring is slidably connected to the limit frame, and the spring four can drive the limit column to automatically reset through elastic force.

[0030] The principle of the optimization scheme of the present invention is that when in use, the pull ring is pulled, and the pull ring drives the limit column to move through the moving rod and presses the spring four. When the limit column is separated from the rotating frame, the limit frame can be removed from the rotating frame, and then the round tube in the disc of the decal paper tape is slid to the outside of the rotating frame. After the sliding is completed, the limit frame is slid to the outside of the rotating frame, and the decal paper tape is squeezed and limited. At the same time, the pull ring is released, and the spring four is reset. The spring four can drive the limit column to slide into the inside of the rotating frame through elastic force, so that the decal paper tape can be quickly replaced.

[0031] Then turn on the printer and start the motor at the same time. The motor drives the corresponding rotating frame to rotate. The rotating frame can reel in the printed decal paper tape during the rotation process. During the reeling process, the decal paper tape drives another rotating frame to rotate. During the rotation process, the rotating frame can drive the rubber ring to rotate. During the rotation process, the rubber ring can slow down the rotation of the rotating frame through the friction between the circular arc rubber block, and can apply resistance to the released decal paper tape. The resistance can tighten the decal paper tape, so that the rotating frame on one side of the motor can be reeled more tightly, and in the process of the decal paper tape moving, the tensioning roller 2 can be driven by the spring 2 to drive the decal paper tape to move to the inner side of the fixed frame. While moving, it can be tightened again by the supporting force of the support roller 1 and the support roller 2. When the decal paper tape enters the interior of the printer, the knob is turned, and the knob drives the screw to rotate. The screw can drive the adjustment bar to move by cooperating with the thread between the fixed frame, and adjust the length of the spring 1. After adjustment, it can be pushed downward by the tensioning roller 1, so that the decal paper tape can enter the interior of the printer in an unfolded manner, thereby effectively improving the printing quality.

[0032] The beneficial effects of the present invention are as follows: by adding structures such as a rubber ring, a first tensioning roller and a second tensioning roller on the base, the present invention can increase the release resistance of the decal paper tape through the friction between the rubber ring and the arc rubber block during use, which can effectively increase the winding force, and in the process of transmission, the decal paper tape can be further tightened by the first tensioning roller and the second tensioning roller, thereby effectively improving the printing quality of the decal paper tape, and the decal paper tape can be limited by a limit frame, and when replacement is needed, the decal paper tape can be conveniently replaced by simply disassembling the limit frame.

[0042] The fixing frame 7 is rotatably connected to the upper surface of the base 1. The upper surface of the base 1 is provided with a mounting countersunk hole, and the mounting countersunk hole is provided with an electric drive unit 101 for driving the fixing frame 7 to rotate on the upper surface of the base 1.

[0043] Two first pressure detection units 102 are respectively provided at both ends of the support roller 11, two second pressure detection units 103 are respectively provided at both ends of the support roller 2 12, and a first Hall unit 104 and a second Hall unit 105 are respectively provided in the support roller 1 11 and the support roller 2 12.

[0044] The two first pressure detection units 102 are respectively used to collect pressure information on both ends of the support roller 11, and distinguish the pressure information into first left pressure information and first right pressure information; the two second pressure detection units 103 are respectively used to collect pressure information on both ends of the support roller 2 12, and distinguish the pressure information into second left pressure information and second right pressure information; the first Hall unit 104 is used to collect first speed information of the support roller 11; the second Hall unit 105 is used to collect second speed information of the support roller 2 12;

[0045] The motor 14, the electric drive unit 101, the two first pressure detection units 102, the two second pressure detection units 103, the first Hall unit 104 and the second Hall unit 105 are respectively connected to the control module signal;

[0046] The control module is used to receive the first left pressure information, the first right pressure information, the second left pressure information, the second right pressure information, the first speed information and the second speed information; the control module is also used to generate an angle adjustment instruction when the deviation value of the second left pressure information and the second right pressure information exceeds a preset value, the angle adjustment instruction includes a rotation direction, and send the angle adjustment instruction to the electric drive unit 101, and the electric drive unit 101 is used to adjust the relative angle between the fixed frame 7 and the base 1 after receiving the angle adjustment instruction; the control module is also used to generate a deceleration instruction and send it to the motor 14 after either the first left pressure information or the first right pressure information exceeds a preset threshold value, and the motor 14 decelerates after receiving the deceleration instruction. Low rotation speed; the control module is also used to generate a stop command after either the first left pressure information or the first right pressure information is lower than a preset warning value, and the motor 14 stops rotating after receiving the stop command; the control module is also used to generate a pre-alarm message after the change speed of either the first left pressure information or the first right pressure information exceeds a preset value. At this time, if the change speeds of the second left pressure information and the second right pressure information do not exceed the preset value, and the deviation value of the first speed information and the second speed information does not exceed the preset range, the pre-alarm message is released; if the change speeds of the second left pressure information and the second right pressure information exceed the preset value, or the deviation value of the first speed information and the second speed information exceeds the preset range, an alarm message is generated.

[0047] When used specifically: the motor 14 can be a stepper motor or a servo motor, because they provide precise speed and position control. Power: Determined by the weight of the decal tape 10 and the winding speed, it may usually be between tens of watts and hundreds of watts. Speed: It should be able to support a wide range of speed regulation to accommodate different printing speeds and winding requirements. Torque: Sufficient torque is required to drive the rotating frame 8 and the decal tape 10, while taking into account the inertia during starting and stopping.

[0048] The electric drive unit 101 should be selected to support digital or analog signal control to receive instructions from the control module. Output power: needs to match the power of the motor 14 to ensure that sufficient driving force can be provided. Control accuracy: can accurately control the speed and position of the motor 14 to achieve fine winding control.

[0049] The first pressure detection unit 102 should be selected to cover the maximum and minimum pressures that may occur during normal printing of the decal paper strip 10. Accuracy: high sensitivity and accuracy to ensure that small changes in pressure can be accurately detected. Response time: fast response to adjust the speed of the motor 14 or the angle of the fixing frame 7 in time. The second pressure detection unit 103 is the same as the first pressure detection unit 102 to ensure consistency.

[0050] The first Hall element 104 (support roller 11) should be selected to cover the rotation speed range of the support roller 11 in normal operation. Resolution: high resolution to ensure that small changes in rotation speed can be accurately measured. Output signal: should be able to provide a clear digital or analog signal for the control module to read. The second Hall element 105 (support roller 2 12) is the same as the first Hall element 104.

[0051] Specifically, in this embodiment, the motor 14 is selected as a stepper motor. The specific model can be considered as NEMA 17 or NEMA 23 stepper motors. These motors 14 are widely used due to their cost-effectiveness and easy control. Servo motors can also be selected: such as Panasonic Minas A5 series or Siemens S1FU series. These motors 14 provide higher control accuracy and dynamic response. In this embodiment, a NEMA 23 stepper motor is selected.

[0052] The electric drive unit 101 may be a stepper motor driver, such as Trinamic TMC2130 or DRV8825, which provide micro-step control. Servo drivers may also be considered, such as Yaskawa SGDM or Baldor DPG series, which support advanced control algorithms and network communications. In this embodiment, the Yaskawa SGDM servo driver is selected (of course, the angles of the base 1 and the fixed frame 7 are adjusted by a lead screw after a reducer).

[0053] The first pressure detection unit 102 (support roller 1 11, both left and right) may consider strain gauge sensors: such as Honeywell SS93A or Meggitt Sensing LL series, which can accurately measure pressure changes. Capacitive pressure sensors may also be considered: such as TE Connectivity 46FRA series, which are suitable for applications requiring high sensitivity and fast response. In this embodiment, the Honeywell SS93A strain gauge sensor is selected. The second pressure detection unit 103 (support roller 2 12) is the same as the first pressure detection unit 102.

[0054] The first Hall unit 104 (support roller 11, both left and right) can be an incremental encoder, such as Sick LIDAR TiM series or Baumer ODS series, to provide high-precision position and speed feedback. Or an absolute encoder, such as Renishaw RESOLUTE series, to provide single-turn and multi-turn position information. In this embodiment, the Sick LIDAR TiM incremental encoder is used. The second Hall unit 105 (support roller 2 12) can be the same as the first Hall unit 104.

[0055] After the system is started, the control module is initialized and ready to receive signals from various sensors.

[0056] Then, the decal tape 10 is fed into the printer 2 through the auxiliary tensioning mechanism 6, at which time the first pressure detection unit 102 and the second pressure detection unit 103 begin to monitor the pressure information at both ends of the support roller 1 11 and the support roller 2 12. The control module receives the first left pressure information, the first right pressure information, the second left pressure information, and the second right pressure information in real time.

[0057] The printer 2 starts printing the decal tape 10. At this time, the first Hall unit 104 and the second Hall unit 105 monitor the rotation speed information of the support roller 1 11 and the support roller 2 12. The decal tape 10 after printing is rolled up by the rotating frame 8. The electric drive unit 101 adjusts the relative angle between the fixed frame 7 and the base 1 according to the command of the control module to ensure that the decal tape 10 is rolled up evenly.

[0058] The control module continuously receives information from the pressure detection unit and the Hall unit and analyzes it.

[0059] If the deviation between the second left pressure information and the second right pressure information exceeds a preset value, the control module generates an angle adjustment instruction to adjust the angle of the fixing frame 7 through the electric drive unit 101 to correct the deviation during the winding process.

[0060] If either the first left pressure information or the first right pressure information exceeds a preset threshold, the control module will generate a deceleration instruction to reduce the rotation speed of the motor 14 to reduce the tension of the paper tape.

[0061] If any pressure information is lower than the preset warning value, the control module will generate a stop command and the motor 14 will stop rotating to prevent the paper tape from being damaged.

[0062] When the change speed of the first left pressure information and the first right pressure information exceeds a preset value, but other conditions do not trigger an alarm, the control module will generate a pre-alarm message to alert the operator.

[0063] If the change speed of the second left pressure information and the second right pressure information exceeds a preset value, or the deviation value of the first speed information and the second speed information exceeds a preset range, the control module will generate an alarm message to instruct the operator to take immediate action. During the printing process, if the decal tape 10 needs to be replaced or maintenance is required, the quick change mechanism 9 can quickly complete the replacement of the tape to reduce downtime.

[0064] After the printing task is completed, the system can be safely shut down according to the predetermined procedure, all mechanical parts stop working and wait for the next start-up.

The spring three 606 can push the arc rubber block 607 to the outside of the rubber ring 603 through elastic force to increase the resistance between the rubber ring 603 and the arc rubber block 607.

[0066] like Figure 1 , Figure 3 , Figure 6As shown, the quick change mechanism 9 includes a limit frame 91, the outer side of the rotating frame 8 is slidably connected to the limit frame 91, the limit frame 91 is in contact with the decal paper tape 10, the inner side of the limit frame 91 is slidably connected to a moving rod 92, the end of the moving rod 92 close to the rotating frame 8 is fixedly connected to a limiting column 93, a spring four 94 is arranged on the outer side of the moving rod 92, the end of the moving rod 92 away from the limiting column 93 is fixedly connected to a pull ring 95, the pull ring 95 is slidably connected to the limit frame 91, the limit frame 91 can limit the decal paper tape 10, one end of the spring four 94 is fixedly connected to the limit column 93, the limit column 93 is slidably connected to both the rotating frame 8 and the limit frame 91, and the spring four 94 can drive the limit column 93 to automatically reset through elastic force.

[0067] The specific implementation process of the present invention is as follows: when in use, pull the pull ring 95, the pull ring 95 drives the limit column 93 to move through the moving rod 92, and presses the spring four 94. When the limit column 93 is separated from the rotating frame 8, the limit frame 91 can be removed from the rotating frame 8, and then the round tube in the disc of the decal paper tape 10 is slid to the outside of the rotating frame 8. After the sliding is completed, the limit frame 91 is slid to the outside of the rotating frame 8, and the decal paper tape 10 is squeezed and limited. At the same time, the pull ring 95 is released, and the spring four 94 is reset. The spring four 94 can drive the limit column 93 to slide into the inside of the rotating frame 8 through elastic force, so that the decal paper tape 10 can be quickly replaced;

[0068] Then, the printer 2 is turned on, and the motor 14 is started at the same time. The motor 14 drives the corresponding rotating frame 8 to rotate. The rotating frame 8 can reel in the printed decal tape 10 during the rotation. During the reeling process, the decal tape 10 drives another rotating frame 8 to rotate. The rotating frame 8 can drive the rubber ring 603 to rotate during the rotation. The rubber ring 603 can slow down the rotation of the rotating frame 8 through the friction between the circular arc rubber block 607 during the rotation, and can apply resistance to the release of the decal tape 10. The resistance can tighten the decal tape 10, so that the rotating frame 8 on one side of the motor 14 can be reeled more tightly, and the decal tape 10 can be rolled up. During the movement, the spring 2 60 can drive the tensioning roller 2 602 to drive the decal paper tape 10 to move toward the inner side of the fixed frame 7. While moving, it can be tightened again through the supporting force of the support roller 11 and the support roller 2 12. When the decal paper tape 10 enters the interior of the printer 2, the knob 67 is turned, and the knob 67 drives the screw 66 to rotate. The screw 66 can drive the adjustment bar 65 to move through the threaded cooperation with the fixed frame 61, and adjust the length of the spring 1 68. After adjustment, it can be pushed downward by the tensioning roller 1 64, so that the decal paper tape 10 can enter the interior of the printer 2 in an unfolded manner, thereby effectively improving the printing quality.

[0069] By adding structures such as a rubber ring 603, a tensioning roller 1 64 and a tensioning roller 2 602 on the base 1, the present invention can increase the release resistance of the decal paper tape 10 through the friction between the rubber ring 603 and the arc rubber block 607 during use, which can effectively increase the winding force, and in the process of transmission, the decal paper tape 10 can be further tightened by the tensioning roller 1 64 and the tensioning roller 2 602, thereby effectively improving the printing quality of the decal paper tape 10, and the decal paper tape 10 can be limited by the limit frame 91. When replacement is needed, the decal paper tape 10 can be conveniently replaced by simply removing the limit frame 91.

[0070] In another embodiment, a strain gauge is provided between the spring 68 and the roller frame 63, and the strain gauge is bonded and fixed to the roller frame 63. The interior of the tensioning roller 64 is hollow and filled with a number of evenly distributed heating resistors. A power receiving coil is provided at one end of the tensioning roller 64, and a thermistor is provided on the roller frame 63. A power supply coil is provided at a position of the roller frame 63 opposite to the power receiving coil (in this embodiment, it is located at the end where the roller frame 63 contacts the tensioning roller 64, and non-contact power supply is achieved through the coil to increase the temperature of the heating resistor). The strain gauge, the power supply coil, the heating resistor and the thermistor are connected to a control module (either a PLC or a single-chip microcomputer, and a PLC is selected in this embodiment).

[0071] The working / control logic of this embodiment is to collect the close contact degree between the tension roller 164 and the decal paper tape 10 through the strain gauge. Since some existing decal paper tapes 10 are water transfer decals, which are a kind of paper with particularly strong water absorption, and the surface is all hydrosol (dissolved only in water, and not sticky in dry state), after printing is completed, the printed decal paper is soaked in water, and after the paper absorbs water, the hydrosol on the surface is dissolved, and the printed pattern remains on the water surface (similar to water transfer technology).

[0072] Therefore, the power supply coil supplies power, the power receiving coil receives the power, and then the power is converted into heat energy through the heating resistor to pre-dry the decal tape 10 (and dry it after printing). The reading of the strain gauge can characterize the force of the decal tape 10 on the tension roller 64, which can be used as a basis for adjusting the warning force of the decal tape 10. It can also be used as a basis for adjusting the power of the power supply coil. The main reason is that the contact area between the decal tape 10 and the tension roller 64 is small (ideally a line, but actually a rectangle with width), resulting in very fast temperature transfer. Even if a thermistor is added as feedback, the time lag characteristics of the temperature control process (closed-loop automatic control system) cannot be ignored. That is, if the temperature of the power supply coil is constant, when the interaction force between the decal tape 10 and the tension roller 64 is insufficient, the temperature transfer is slow and the drying effect is weak; or if the interaction force between the decal tape 10 and the tension roller 64 is large, the temperature transfer is fast, so that the decal tape 10 is over-dried, affecting the product quality. Furthermore, by printing after drying, the ink pattern can be better combined with the decal paper tape 10, thereby improving product quality.

[0073] Therefore, in this embodiment, the strain gauge is also used as the input of the temperature control system, the thermistor is used as the feedback of the temperature control system (according to the deformation of the strain gauge, an adjustment coefficient is made for the parameters of the thermistor), and the power of the power supply coil is used as the output. In this way, the drying effect of the product can be guaranteed, the printing quality of the product can be improved, and the consistency of product quality can be ensured.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
