Description

Technical Field

[0001] The invention belongs to the technical field of RFID label production, and in particular relates to a slitting device for RFID label production. Background Art

[0002] Amid the booming development of modern IoT technology, RFID (Radio Frequency Identification) has gained widespread application as a key means of information collection and identification. RFID tags are an integral component of RFID systems, and their production quality and efficiency directly impact the performance and effectiveness of the entire RFID system.

[0003] In the production process of RFID tags, slitting is a crucial process. Traditional RFID tag slitting equipment has exposed many problems in practical applications.

[0004] 1. If the adhesion between the label surface material and the base material is not well controlled, adhesion may occur during slitting, resulting in incomplete slitting and making it difficult to separate the labels after slitting, affecting production efficiency and product quality;

[0005] 2. During the slitting process, friction between the material and the cutting tools and equipment can easily generate static electricity. This static electricity can attract dust and other impurities, making the label surface unclean and affecting subsequent printing and packaging processes. In severe cases, it can also damage electronic components, affecting the performance of RFID tags and even cause sparks, posing a safety hazard.

[0006] In summary, the development of a slitting device for RFID tag production that can improve slitting accuracy, increase production efficiency and reduce the impact of static electricity has important practical significance and market value. Summary of the Invention

[0007] The purpose of the present invention is to provide a slitting device for producing RFID tags to solve the problem that existing RFID tags are not completely slit and are easy to stick together.

[0008] The present invention is achieved through the following technical solutions:

[0009] A slitting device for RFID tag production includes a frame, the upper end of the frame is arranged on a workbench, the upper end of the workbench is provided with a support frame, the upper end of the support frame is provided with two unwinding rolls at the left upper end, and two taking-up rolls at the lower end, a slitting top plate is provided at the upper right end of the support frame, and a slitting mechanism is provided below the slitting top plate for automatically cutting RFID tags on the RFID tag roll, and the support frame is provided with a discharging mechanism below the slitting mechanism for conveying the cut RFID tags out; a plurality of guide rollers are provided on the support frame, and after the RFID tag roll is unwound from the unwinding roll, it passes through the plurality of guide rollers in sequence and is wound onto the taking-up roll, and the RFID tag roll passes between the slitting top plate and the slitting mechanism, and a winding motor is provided on the outer side of the taking-up roll, which drives the taking-up roll to rotate by the winding motor to realize the winding and unwinding action.

[0010] Preferably, the slitting mechanism includes fixed brackets symmetrically arranged on both sides of the support frame, a sliding rod and a bidirectional threaded rod are respectively provided between the two fixed brackets, the two ends of the sliding rod are respectively fixedly connected to the two fixed brackets, and the two ends of the bidirectional threaded rod are respectively rotatably connected to the two fixed brackets; a movable seat is symmetrically sleeved on the sliding rod and the bidirectional threaded rod, the movable seat is slidably arranged between the sliding rod and is threadedly connected to the bidirectional threaded rod; one end of the bidirectional threaded rod passes through the fixed bracket and is connected to a driving wheel; a telescopic cylinder is installed on each of the movable seats, and a cutter head assembly is provided at the movable end of the telescopic cylinder, and the cutter head assembly is a double-cutter head arrangement.

[0011] When in use, the bidirectional threaded rod can be driven to rotate by rotating the driving wheel, thereby adjusting the position of the movable seat and the cutter head assembly. The telescopic cylinder drives the cutter head assembly up and down to cut the RFID tag on the RFID tag roll.

[0012] Preferably, the cutter head assembly comprises an outer cutter head and an inner cutter head, the inner cutter head being movably arranged in the inner cavity of the outer cutter head, and the cutting edge of the inner cutter head is lower than the cutting edge of the outer cutter head; the middle part of the lower end of the outer cutter head is connected to an outer sleeve, the middle part of the lower end of the inner cutter head is connected to an inner rod, the inner rod extends downward through the outer sleeve and is connected to the movable end of the telescopic cylinder; a limit plate is provided on the lower outer wall of the inner rod, and a first spring is sleeved on the outer side of the outer sleeve, the lower end of the first spring is in contact with the limit plate, and the upper end is in contact with the lower end surface of the outer cutter head, and the first spring is in a compressed state;

[0013] A spring plate is provided in the inner cavity of the inner cutter head. The spring plate is arranged at an angle, and the lower end of the spring plate is connected to the bottom of the inner cavity of the inner cutter head via a spring matrix composed of a plurality of second springs. The spring length on one side of the spring matrix is ​​greater than the spring length on the other side, thereby ensuring that the spring plate is in an inclined state.

[0014] When in use, the telescopic cylinder drives the inner rod, inner cutter head, and outer cutter head to rise synchronously. Since the blade of the outer cutter head is at a high position, it first contacts the RFID tag roll and directional cuts the RFID tag roll to the top plate, thereby cutting the RFID tag on the RFID tag roll. The telescopic cylinder continues to rise, the first spring is compressed, and the inner rod drives the inner cutter head upward to perform a second cut on the RFID tag roll, thereby fully cutting off the connection between the RFID tag and the base material, avoiding incomplete cutting and adhesion.

[0015] At the same time, during the rising process of the inner cutter head, the spring plate contacts the RFID tag roll and the second spring is compressed. When the slitting is completed, when the cutter head assembly descends, due to the different elastic forces of the second springs on both sides of the lower end of the spring plate, the spring plate is subjected to the elastic force of the second spring and the cut RFID tag is bounced to one side, so that it falls onto the discharge mechanism below.

[0016] Preferably, a plurality of air outlet holes are provided at the bottom of the inner cutter head, and a rectangular through hole is provided on the higher side of the spring plate.

[0017] When the inner cutter head rises, a cavity is formed between the outer cutter head and the inner cutter head. When the cutter head assembly descends, the outer cutter head moves upward relative to the inner cutter head under the action of the first spring, thereby squeezing the cavity between the outer cutter head and the inner cutter head, causing the internal gas to instantly eject from the air outlet and pass through the edge of the spring plate and the rectangular through-hole, blowing the cut RFID tag to one side, further allowing the RFID tag to smoothly fall onto the discharge mechanism below.

[0018] Preferably, the discharging mechanism includes a conveyor belt, a conveyor motor and a conveyor bracket. The conveyor brackets are symmetrically provided on both sides of the fixed bracket. The upper end of the conveyor bracket is rotatably provided with a rotating shaft. The two ends of the conveyor belt are rotatably sleeved on the two rotating shafts. The conveyor motor is installed on the outside of one of the conveyor brackets, and the output end of the conveyor motor is connected to the end of the rotating shaft. When in use, the conveyor belt is driven to rotate by the rotation of the conveyor motor, thereby conveying out the RFID tag that falls on the conveyor belt.

[0019] Preferably, a baffle is provided at the right end of the fixed bracket, and the lower end of the baffle is at the same height as the upper end surface of the conveyor belt, which is used to block the RFID tag ejected by the ejection plate and make it fall smoothly onto the conveyor belt.

[0020] Preferably, a humidity control mechanism is further provided in the middle of the fixed bracket, and the humidity control mechanism includes a humidifier, a connecting pipe, a support plate, a drive box, a spray pipe, and a spray pipe bracket; the humidifier is mounted on the lower part of the fixed bracket through a mounting bracket, and the two ends of the support plate are connected to the two sides of the fixed bracket, and spray pipe brackets are symmetrically provided on both sides of the upper end of the support plate, and the two ends of the spray pipe are rotatably mounted on the two spray pipe brackets, the drive box is cylindrical and fixedly mounted on the outer wall of one of the spray pipe brackets, and an air inlet is provided at the lower end of the drive box, and the air inlet is connected to the air outlet of the humidifier through the connecting pipe;

[0021] One end of the injection pipe is sealed, and the other end passes through the injection pipe bracket and extends into the drive box, with a gap retained between the injection pipe and the interior of the drive box. The injection pipe is provided with multiple fan plates on the outside of the inner end of the drive box; and a plurality of spray holes are provided on the outer wall of the injection pipe.

[0022] When the humidified gas enters the drive box from the humidifier, it will drive the fan plate to rotate, thereby driving the injection tube to rotate. At the same time, the gas entering the drive box will enter the inner cavity from the end opening of the spray pipe, and finally flow out from the nozzle of the injection tube. The humidified gas is used to maintain the humidity around the slitting mechanism to avoid static electricity generated by drying and damage to the RFID tag product.

[0023] Preferably, a cover plate is further provided at the upper end of the rack, and the lower end of the cover plate is connected to the four corners of the rack through four connecting columns to provide safety protection and prevent dust from falling onto the equipment.

[0024] Preferably, a controller is provided on the front of the frame, and the controller is electrically connected to the winding motor, the telescopic cylinder, the conveying motor and the humidifier respectively, and controls their operation.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The present invention integrates the unwinding reel and the receiving reel on a single frame and arranges them in an up-down staggered arrangement, thereby reducing the overall space occupied by the slitting equipment. The slitting equipment can also slit two rolls of RFID tag material at the same time, thereby improving work efficiency.

[0027] 2. The cutter head assembly in the present invention consists of an outer cutter head and an inner cutter head, which can perform primary cutting and secondary cutting on the RFID tag roll, thereby fully cutting off the connection between the RFID tag and the base material, avoiding incomplete cutting and adhesion.

[0028] 3. The present invention sets an inclined spring plate in the inner cavity of the inner cutter head. Under the action of the second spring, the cut RFID tag can be bounced to one side and fall onto the discharge mechanism below to avoid affecting the next cutting.

[0029] 4. The present invention provides an air outlet at the bottom of the inner cutter head and a rectangular through hole on the higher side of the spring plate. By squeezing the cavity between the outer cutter head and the inner cutter head, the internal gas is instantly ejected from the air outlet, passes through the edge of the spring plate and the rectangular through hole, and blows the cut RFID tags to one side, further allowing the RFID tags to smoothly fall onto the discharge mechanism below.

[0030] 5. The present invention maintains humidity around the slitting mechanism by setting a humidity control mechanism to avoid static electricity generated by drying and damaging RFID tag products. The flowing gas drives the spray pipe to rotate automatically, so that the moist gas can be blown evenly, thereby increasing the moistening effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Among them, see Figure 3 The slitting mechanism 3 includes fixed brackets 301 symmetrically arranged on both sides of the support frame 11, and a sliding rod 303 and a bidirectional threaded rod 304 are respectively provided between the two fixed brackets 301, and the two ends of the sliding rod 303 are respectively fixedly connected to the two fixed brackets 301, and the two ends of the bidirectional threaded rod 304 are respectively rotatably connected to the two fixed brackets 301; a movable seat 302 is symmetrically sleeved on the sliding rod 303 and the bidirectional threaded rod 304, and the movable seat 302 is slidably arranged between the sliding rod 303 and the bidirectional threaded rod 304, and is threadedly connected to the bidirectional threaded rod 304; one end of the bidirectional threaded rod 304 passes through the fixed bracket 301 and is connected to a driving wheel 307; a telescopic cylinder 305 is installed on each movable seat 302, and a cutter head assembly 306 is provided at the movable end of the telescopic cylinder 305, and the cutter head assembly 306 is a double-cutter head arrangement.

[0053] When in use, the bidirectional threaded rod 304 can be driven to rotate by rotating the driving wheel 307, thereby adjusting the position of the movable seat 302 and the cutter head assembly 306, and the telescopic cylinder 305 drives the cutter head assembly 306 to move up and down to cut the RFID label on the RFID label roll 12.

[0054] See also Figures 6-10The cutter head assembly 306 includes an outer cutter head 3061 and an inner cutter head 3062. The inner cutter head 3062 is movably arranged in the inner cavity of the outer cutter head 3061, and the cutting edge of the inner cutter head 3062 is lower than the cutting edge of the outer cutter head 3061; the middle part of the lower end of the outer cutter head 3061 is connected to an outer sleeve 3065, and the middle part of the lower end of the inner cutter head 3062 is connected to an inner rod 3066. The inner rod 3066 extends downward through the outer sleeve 3065 and is connected to the movable end of the telescopic cylinder 305; a limit plate is provided on the lower outer wall of the inner rod 3066, and a first spring 3064 is provided on the outer surface of the outer sleeve 3065.

[0055] A spring plate 3063 is provided within the inner cavity of the inner cutter head 3062. The spring plate 3063 is tilted, and the lower end of the spring plate 3063 is connected to the bottom of the inner cavity of the inner cutter head 3062 via a spring matrix composed of a plurality of second springs 3067. The spring length on one side of the spring matrix is ​​greater than the spring length on the other side, thereby ensuring that the spring plate 3063 is tilted.

[0056] When in use, the telescopic cylinder 305 drives the inner rod 3066, the inner cutter head 3062, and the outer cutter head 3061 to rise synchronously. Since the blade of the outer cutter head 3061 is at a high position, it first contacts the RFID tag roll 12 and directionally cuts the RFID tag roll 12 into the top plate 4, thereby cutting the RFID tag on the RFID tag roll 12. The telescopic cylinder 305 continues to rise, the first spring 3064 is compressed, and the inner rod 3066 drives the inner cutter head 3062 upward to cut the RFID tag roll 12 a second time, thereby fully cutting off the connection between the RFID tag and the base material, avoiding incomplete cutting and adhesion.

[0057] At the same time, during the rising process of the inner cutter head 3062, the spring plate 3063 contacts the RFID tag roll 12, and the second spring 3067 is compressed. When the cutting is completed, when the cutter head assembly 306 descends, due to the different elastic forces of the second springs 3067 on both sides of the lower end of the spring plate 3063, the spring plate 3063 is subjected to the elastic force of the second spring 3067, and the cut RFID tag is bounced to one side, so that it falls onto the discharge mechanism 10 below.

[0059] When the inner cutter head 3062 rises, a cavity is formed between the outer cutter head 3061 and the inner cutter head 3062. When the cutter head assembly 306 descends, the outer cutter head 3061 moves upward relative to the inner cutter head 3062 under the action of the first spring 3064, thereby squeezing the cavity between the outer cutter head 3061 and the inner cutter head 3062, causing the internal gas to instantly eject from the air outlet 3069, and pass through the edge of the elastic plate 3063 and the rectangular through hole, blowing the cut RFID tag to one side, further allowing the RFID tag to smoothly fall onto the discharge mechanism 10 below.

[0061] A baffle 13 is provided at the right end of the fixed bracket 301 , and the lower end of the baffle 13 is at the same height as the upper end surface of the conveyor belt 1001 , and is used to block the RFID tag ejected by the ejection plate 3063 so that it falls smoothly onto the conveyor belt 1001 .

[0062] Example 2

[0063] In order to reduce the risk of static electricity generated by the slitting equipment during slitting and damaging the RFID tags, this embodiment adds the following solutions based on the first embodiment:

[0064] See also Figure 11 and Figure 12 , a humidity control mechanism 9 is also provided in the middle of the fixed bracket 301, and the humidity control mechanism 9 includes a humidifier 901, a connecting pipe 902, a support plate 903, a drive box 904, a spray pipe 905, and a spray pipe bracket 906; the humidifier 901 is installed on the lower part of the fixed bracket 301 through a mounting frame, and the two ends of the support plate 903 are connected to the two sides of the fixed bracket 301. Spray pipe brackets 906 are symmetrically provided on both sides of the upper end of the support plate 903, and the two ends of the spray pipe 905 are rotatably mounted on the two spray pipe brackets 906. The drive box 904 is cylindrical and fixedly mounted on the outer wall of one of the spray pipe brackets 906. The lower end of the drive box 904 is provided with an air inlet, and the air inlet is connected to the air outlet of the humidifier 901 through the connecting pipe 902;

[0065] One end of the injection pipe 905 is sealed, and the other end passes through the injection pipe bracket 906 and extends into the drive box 904, with a gap retained between the injection pipe 905 and the interior of the drive box 904. A plurality of fan plates 907 are provided on the outside of the inner end of the injection pipe 905 located in the drive box 904; a plurality of spray holes 908 are provided on the outer wall of the injection pipe 905.

[0066] When the humidified gas enters the drive box 904 from the humidifier 901, it will drive the fan plate 907 to rotate, thereby driving the injection tube 905 to rotate. At the same time, the gas entering the drive box 904 will enter the inner cavity from the end opening of the spray pipe, and finally flow out from the nozzle 908 of the injection tube 905. The humidified gas is used to maintain the humidity around the slitting mechanism 3 to avoid static electricity generated by drying and damage to the RFID tag product.

[0067] A cover plate 102 is located at the top of the frame 1. The bottom of the cover plate 102 is connected to the four corners of the frame 1 via four connecting posts, providing safety protection and preventing dust from falling onto the equipment. A controller 101 is located on the front of the frame 1. This controller 101 is electrically connected to the winding motor 8, telescopic cylinder 305, conveying motor 1002, and humidifier 901, controlling their operation.

[0068] Working principle of the present invention:

[0069] When in use, the RFID tag roll 12 is mounted on the unwinding roll 6, and the end of the RFID tag roll 12 is passed through the five guide rollers 5 (such as Figure 3The RFID tag on the RFID tag roll 12 is wound on the reel 7, and the reeling motor 8 is started. The reeling motor 8 drives the reel 7 to reel and unwinds the unwinding roll 6 at the same time. The controller 101 controls the telescopic cylinder 305 to extend, driving the inner rod 3066, the inner cutter head 3062, and the outer cutter head 3061 to rise synchronously. Since the blade of the outer cutter head 3061 is at a high position, it first contacts the RFID tag roll 12 and directionally cuts the RFID tag roll 12 into the top plate 4, thereby cutting the RFID tag on the RFID tag roll 12. The telescopic cylinder 305 continues to rise, the first spring 3064 is compressed, and the inner rod 3066 drives the inner cutter head 3062 to cut the RFID tag roll 12 a second time, thereby fully cutting off the RFID tag. The connection between the tag and the base material is to avoid incomplete cutting and adhesion. At the same time, during the rising process of the inner cutter head 3062, the spring plate 3063 contacts the RFID tag roll 12, and the second spring 3067 is compressed. When the cutting is completed, the cutter head assembly 306 descends. Due to the different elastic forces of the second springs 3067 on both sides of the lower end of the spring plate 3063, the spring plate 3063 is subjected to the elastic force of the second spring 3067, and the cut RFID tag is bounced to one side, so that it falls onto the discharge mechanism 10 below. The conveying motor 1002 then rotates to drive the conveyor belt 1001 to rotate, thereby conveying the RFID tag that falls on the conveyor belt 1001 out.

[0070] At the same time, the humidifier 901 is working. After the humidified gas enters the drive box 904 from the humidifier 901, it will drive the fan plate 907 to rotate, thereby driving the injection tube 905 to rotate. At the same time, the gas entering the drive box 904 will enter the inner cavity from the end opening of the water spray pipe, and finally flow out from the nozzle 908 of the injection tube 905. The humidified gas is used to maintain the humidity around the slitting mechanism 3 to avoid static electricity generated by drying and damage to the RFID tag product; and the flowing gas drives the injection tube 905 to rotate automatically, so that the humidified gas can be blown away evenly, thereby increasing the wetting effect.
