Description

Technical Field

[0001] This application relates to the technical field of printing equipment, and in particular to a label silver coating screen printing apparatus. Background Technology

[0002] Scratch-off silver anti-counterfeiting labels, also known as scratch-off digital anti-counterfeiting labels, refer to labels where the corresponding query code is obtained by scratching off the silver coating. The label works on the principle of digital anti-counterfeiting. After obtaining the anti-counterfeiting code, the authenticity of the label can be verified through the specified query method on the label. The silver coating is applied to the anti-counterfeiting label through a screen printing production line.

[0003] Currently, the aforementioned screen printing production line mainly includes an unwinding mechanism, a screen printing machine, a first drying mechanism, a text printing mechanism, a second drying mechanism, and a rewinding mechanism. After unwinding, the anti-counterfeiting label is fed into the screen printing machine, which prints a silver coating onto the anti-counterfeiting label. Then, the first drying mechanism dries the silver coating, and text is printed on the dried silver coating surface. After the text printing is completed, the second drying mechanism dries the ink on the text. This completes the processing of the silver coating on the anti-counterfeiting label. Finally, the rewinding mechanism rewinds the processed anti-counterfeiting label.

[0004] Regarding the aforementioned technologies, since the silver coating has not yet been fixed to the anti-counterfeiting label after screen printing, it is impossible to use conveyor rollers to transport the anti-counterfeiting label. Similarly, after the text printing is completed, the ink has not yet been fixed to the silver coating, so it is impossible to use conveyor rollers to transport the anti-counterfeiting label. For this reason, currently in screen printing production lines, the anti-counterfeiting label is driven through the screen printing mechanism, the first drying mechanism, the text printing mechanism, and the second drying mechanism only by a rewinding mechanism. However, when the production line is too long, relying solely on the rewinding mechanism to provide the conveying power for the anti-counterfeiting label roll will lead to instability in the movement of the anti-counterfeiting label within the production line, which will also affect the printing quality of the silver coating or text on the anti-counterfeiting label. Summary of the Invention

[0005] This application provides a screen printing device for applying silver coating to labels, the purpose of which is to increase the stability of anti-counterfeiting label conveying in screen printing equipment.

[0006] The label silver coating screen printing device provided in this application adopts the following technical solution:

[0007] A screen printing apparatus for label silver coating includes a screen printing machine, the screen printing machine having an inlet and an outlet, and a conveying mechanism being provided on the side of the screen printing machine having the outlet.

[0008] The conveying mechanism includes a combined roller and an auxiliary roller. The combined roller is coaxially connected to a conveying motor. The axes of the combined roller and the auxiliary roller are both arranged in the horizontal direction, and the combined roller is located above the auxiliary roller.

[0009] The combined roller is provided with a plurality of rolling wheels, which are coaxially connected to the combined roller, and the plurality of rolling wheels are arranged sequentially at intervals along the axial direction of the combined roller;

[0010] A plurality of abutment blocks are provided on the outer wall of the rolling wheel, and the plurality of abutment blocks are arranged sequentially at intervals along the circumference of the rolling wheel.

[0011] By adopting the above technical solution, firstly, in the screen printing machine, the anti-counterfeiting label is moved into the screen printing machine through the feed port for screen printing. After the printing is completed, the anti-counterfeiting label with silver coating can be sent out from the discharge port.

[0012] Then, a conveying mechanism is set at the discharge port of the screen printing machine. The conveying mechanism, through the cooperation of combined rollers and auxiliary rollers and driven by the conveying motor, can convey the anti-counterfeiting label outward after it is discharged from the screen printing machine from the discharge port, thereby improving the stability of the conveying in the anti-counterfeiting label production line.

[0013] Several rolling wheels are arranged on the outer side of the combined rollers, and several abutment blocks are arranged sequentially along the outer wall of the rolling wheels along their own axial direction. Therefore, when the anti-counterfeiting label is conveyed by the rolling wheels, the abutment blocks can abut against the anti-counterfeiting label for conveying, and the gap between adjacent abutment blocks can span the silver coating on the anti-counterfeiting label. Therefore, the combined rollers with rolling wheels can convey the anti-counterfeiting label on the side with the silver coating.

[0014] In summary, the combination of rollers in the conveying mechanism enables the transport of anti-counterfeiting labels, thereby increasing the stability of anti-counterfeiting label transport within the production line.

[0015] Optionally, a plurality of abutting rods are provided on the outer side of the combined roller, and the plurality of abutting rods are arranged sequentially at intervals along the circumference of the combined roller. The abutting blocks are arranged in one-to-one correspondence with the abutting rods. The length direction of the abutting rods is arranged parallel to the axial direction of the combined roller. The abutting rods are detachably connected to the plurality of corresponding abutting blocks along their own length direction.

[0016] By adopting the above technical solution and setting the long rod, the contact area between the combined roller and the anti-counterfeiting label can be increased while ensuring the normal conveying of the anti-counterfeiting label by the combined roller, thus further increasing the conveying stability of the anti-counterfeiting label.

[0017] Optionally, the abutment block is slidably connected to the outer wall of the rolling wheel along the circumference of the rolling wheel.

[0018] By adopting the above technical solution, since the contact block and the rolling wheel are slidably connected, the distance between the contact blocks can be adjusted as needed, so that the rolling wheel can meet the requirements of different anti-counterfeiting label printing.

[0019] Optionally, the abutment block is detachably connected to the roller.

[0020] By adopting the above technical solution, since the contact block and the rolling wheel are detachably connected, the number of contact blocks on the rolling wheel can be changed, thus further increasing the adjustment distance of the contact blocks on the rolling wheel, enabling the rolling wheel to meet the requirements of printing more types of anti-counterfeiting labels.

[0021] Optionally, a sliding annular groove is provided on the outer wall of the rolling wheel, and the sliding annular groove is coaxially arranged with the rolling wheel;

[0022] A sliding block is provided on the side of the abutment block facing the rolling wheel. The sliding block is connected to the abutment block, and the sliding block is inserted into the sliding ring groove. The sliding block is slidably connected to the inner wall of the sliding ring groove along the circumference of the rolling wheel.

[0023] The rolling wheel has a plurality of first holes on one axial side, and the plurality of first holes are arranged at intervals along the circumference of the rolling wheel. The first holes are connected to the sliding annular groove.

[0026] By adopting the above technical solution, firstly, a sliding ring groove is provided on the outer side of the rolling wheel, and a sliding block is provided on the side of the abutment block facing the rolling wheel. The sliding block is inserted into the sliding ring groove and slides along the circumference of the rolling wheel and is connected to the inner wall of the sliding ring groove. Therefore, the position of the abutment block on the rolling wheel can be adjusted.

[0027] Secondly, since the rolling wheel has several first holes and the sliding block has a second hole, there is a first hole and a second hole that are coaxially connected. An adjusting bolt is inserted into the first hole and the second hole. Therefore, when the adjusting bolt is inserted, the contact block and the rolling wheel can be connected. When the adjusting bolt is pulled out, the contact block and the rolling wheel can be disassembled.

[0028] Optionally, the roller has an adjustment hole that extends through the roller along the axial direction of the combined roller. The combined roller is inserted into the adjustment hole and slides along its own axial direction against the inner wall of the adjustment hole.

[0029] By adopting the above technical solution, since the rolling wheel has an adjustment hole, and the combined roller is inserted into the adjustment hole, and the combined roller slides along its own axis to the inner wall of the adjustment hole, the position of the rolling wheel and the distance between adjacent rolling wheels can be adjusted along the axis of the rolling wheel.

[0030] Optionally, the combined roller is provided with a locking screw, the locking screw is arranged axially parallel to the combined roller, and both ends of the locking screw are connected to the combined roller;

[0031] A locking hole is provided on one axial side of the rolling wheel, and the locking hole passes through the rolling wheel;

[0032] The locking screw is inserted into the locking hole, and the locking screw slides along its own axial direction with the inner wall of the locking hole;

[0033] The rolling wheel is provided with a nut assembly, which includes a first nut and a second nut. Both the first nut and the second nut are threadedly connected to the locking screw. The rolling wheel is located between the first nut and the second nut along its own axial direction.

[0034] By adopting the above technical solution, firstly, the setting of the locking screw, in conjunction with the locking hole on the rolling wheel, can guide the sliding of the rolling wheel on the combined roller.

[0035] Secondly, the nut assembly allows the first nut and the second nut to be threadedly connected to the locking screw, and the corresponding rolling wheel to be fixed between the first nut and the second nut. Therefore, the nut assembly can fix the position of the rolling wheel along the axial direction of the combined roller.

[0036] Optionally, the combined roller includes a main shaft, one end of which is provided with a fixed disk, and the fixed disk is coaxially connected to the conveying motor;

[0037] A movable disk is coaxially provided at the other end of the main shaft, and the movable disk is detachably connected to the main shaft;

[0038] The rolling wheel is sleeved on the main shaft, and the rolling wheel is slidably connected to the main shaft along its own axial direction.

[0039] By adopting the above technical solution, the combined roller includes a main shaft, which is used to install rolling wheels, and the rolling wheels can be slidably sleeved on the main shaft through their own adjustment holes.

[0040] A fixed plate is installed at one end of the spindle. The fixed plate is fixedly connected to the spindle and coaxially connected to the output motor, which enables the spindle to be driven.

[0041] The other end of the main shaft is coaxially connected to a movable disc, which is detachably connected to the main shaft. Therefore, after removing the movable disc, the rollers can be removed from the main shaft, or new rollers can be installed on the main shaft. Thus, the number of rollers can be changed.

[0042] Optionally, the conveying mechanism further includes an installation assembly, which includes a first installation plate and a second installation plate, the first installation plate and the second installation plate being arranged in parallel, and both the first installation plate and the second installation plate being connected to the screen printing machine;

[0044] The conveyor motor is mounted on the first mounting plate;

[0045] The auxiliary roller is located between the first mounting plate and the second mounting plate along its own axial direction, and the auxiliary roller is rotatably connected to both the first mounting plate and the second mounting plate.

[0046] By adopting the above technical solution, the first mounting plate and the second mounting plate in the mounting assembly can provide mounting positions for the combined roller and the auxiliary roller, and realize the connection between the combined roller and the auxiliary roller and the screen printing machine.

[0047] Optionally, a first driving component is provided on the first mounting plate, and a second driving component is provided on the second mounting plate, wherein the driving directions of the first driving component and the second driving component are both arranged in the vertical direction.

[0048] Both the first mounting plate and the second mounting plate are slidably connected to the combined rollers in the vertical direction;

[0050] By adopting the above technical solution, the first driving component and the second driving component are set up, and the combined roller is slidably connected to the first mounting plate and the second mounting plate in the vertical direction. Therefore, the position of the combined roller can be adjusted in the vertical direction by the first driving component and the second driving component, thereby changing the resistance of the combined roller to the anti-counterfeiting label and adjusting the conveying stability of the anti-counterfeiting label.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. This application incorporates a conveying mechanism on a screen printing machine. Through the combination of rollers in the conveying mechanism, the anti-counterfeiting labels can be conveyed, thereby increasing the stability of the anti-counterfeiting label conveying process within the production line.

[0053] 2. When the silver coating of the anti-counterfeiting label roll is set along the length of the anti-counterfeiting label roll, this application uses the cooperation of several rolling wheels on the combined roller to make the gap between adjacent rolling wheels able to span the silver coating of the anti-counterfeiting label roll, so that the combined roller can transport the corresponding anti-counterfeiting label, thereby increasing the transport stability of the anti-counterfeiting label.

[0054] 3. When the length direction of the silver coating of the anti-counterfeiting label roll is set along the width direction of the anti-counterfeiting label roll, this application uses the cooperation of several abutment blocks on the rolling roller to make the gap between adjacent abutment blocks able to cross the silver coating of the anti-counterfeiting label roll, so that the combined roller can transport the corresponding anti-counterfeiting label, thereby increasing the transport stability of the anti-counterfeiting label.

[0065] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0066] A label silver coating screen printing apparatus, as described above Figure 1 The system includes a screen printing machine 1, which comprises a base 11. A screen printing groove 111 is formed on the upper side of the base 11. An inlet 112 and an outlet 113 are respectively formed through opposite side walls of the screen printing groove 111. A screen plate 12 is mounted on the upper side of the base 11, and a scraper 13 is mounted on the upper side of the screen plate 12. A transmission assembly 14 is mounted on the scraper 13. Therefore, when the anti-counterfeiting label moves into the screen printing groove 111 through the inlet 112, the scraper 13, driven by the transmission assembly 14, scrapes the silver coating material on the screen plate 12 onto the anti-counterfeiting label, thereby attaching a silver coating to the upper side of the anti-counterfeiting label. After printing is completed, the anti-counterfeiting label with the attached silver coating is conveyed out of the screen printing machine 1 through the outlet 113.

[0067] Reference Figure 1 and Figure 2A conveying mechanism 2 is provided on one side of the base 11 where the feed inlet 112 is provided. The conveying mechanism 2 includes a combined roller 21 and an auxiliary roller 22. The combined roller 21 and the auxiliary roller 22 are arranged parallel to each other and are both arranged in the horizontal direction. The combined roller 21 is located on the upper side of the auxiliary roller 22. The outer wall of the combined roller 21 and the outer wall of the auxiliary roller 22 are in contact with each other or spaced apart. A conveying motor 23 is coaxially connected to one end of the combined roller 21.

[0068] Therefore, driven by the conveyor motor 23, after the anti-counterfeiting label is discharged from the screen printing machine 1 through the discharge port 113, the anti-counterfeiting label can be conveyed outward with the cooperation of the auxiliary roller 22 and the combination roller 21, thereby improving the stability of the conveying in the anti-counterfeiting label production line.

[0069] Reference Figure 2 and Figure 3 The conveying mechanism 2 also includes a mounting assembly 24, which includes a first mounting plate 241 and a second mounting plate 242. The first mounting plate 241 and the second mounting plate 242 are arranged parallel to each other and are located on both sides of the axial direction of the combined roller 21. Both ends of the combined roller 21 are rotatably connected to the corresponding first mounting plate 241 and the corresponding second mounting plate 242, respectively. Both ends of the auxiliary roller 22 are rotatably connected to the corresponding first mounting plate 241 and the corresponding second mounting plate 242, respectively. Both the first mounting plate 241 and the second mounting plate 242 are detachably connected to the base 11, and the conveying motor 23 is mounted on the first mounting plate 241. Therefore, the mounting assembly 24 enables the mounting of the combined roller 21 and the auxiliary roller 22.

[0070] Reference Figure 2 and Figure 3 The conveying mechanism 2 also includes a pitch adjustment assembly 25, which includes a first drive member 251 and a second drive member 252. The combined roller 21 is slidably connected to both the first mounting plate 241 and the second mounting plate 242 in a vertical direction. The first drive member 251 is disposed on the first mounting plate 241, and the second drive member 252 is disposed on the second mounting plate 242. Both the first drive member 251 and the second drive member 252 are connected to a corresponding end of the combined roller 21, and their driving directions are both vertical. Therefore, the pitch adjustment assembly 25 can adjust the gap between the auxiliary roller 22 and the combined roller 21.

[0071] Reference Figure 3 and Figure 4The first driving component 251 includes a first sliding groove 2511, which extends through the first mounting plate 241 along its thickness direction. The length of the first sliding groove 2511 is vertically oriented. A first sliding block 2512 is inserted into the first sliding groove 2511, and the first sliding block 2512 is slidably connected to the inner wall of the first sliding groove 2511 in the vertical direction. The end of the first sliding groove 2511 corresponding to the combined roller 21 is detachably connected. Therefore, the combined roller 21 can move up and down vertically while rotating normally.

[0072] Reference Figure 3 and Figure 4 The first driving component 251 also includes a mounting base 2513, a driving base 2514, a driving screw 2515, and a driving source 2516. The mounting base 2513 is mounted on the first mounting plate 241. The driving base 2514 is disposed on the first mounting plate 241 and is slidably connected to the mounting base 2513 in the vertical direction. The driving screw 2515 is axially arranged in the vertical direction and is threadedly connected to the driving base 2514. The driving source 2516 is connected to one end of the driving screw 2515, and the driving base 2514 is connected to the first slide block 2512. Therefore, driven by the driving source 2516, the driving screw 2515 can drive the driving base 2514 to move, thereby controlling the combined roller 21 to move in the vertical direction.

[0073] Reference Figure 3 and Figure 4 The drive base 2514 has a first drive hole 2517, which extends through the drive base 2514 and the first slide block 2512 along the axial direction of the combined roller 21. One end of the combined roller 21 is inserted into the first drive hole 2517, and the combined roller 21 is rotatably connected to the inner wall of the first drive hole 2517. The conveyor motor 23 is mounted on the drive base 2514, and the output shaft of the conveyor motor 23 is coaxially connected to the combined roller 21. Therefore, the first drive hole 2517 enables the connection between the conveyor motor 23 and the combined roller 21.

[0074] Reference Figure 3 and Figure 5 The second driving component 252 includes a second slide groove 2521, which extends through the second mounting plate 242 along its thickness direction. The length of the second slide groove 2521 is vertically oriented. A second slide block 2522 is inserted into the second slide groove 2521, and the end of the second slide block 2522 corresponding to the combined roller 21 is detachably connected. Therefore, the cooperation between the second slide groove 2521 and the second slide block 2522, in conjunction with the first driving component 251, enables the combined roller 21 to rise and fall vertically.

[0075] Reference Figure 3 and Figure 5 The second driving component 252 also includes a driving module 2523. The driving module 2523 is a linear module, and its driving direction is set vertically. The driving module 2523 is detachably connected to the second mounting plate 242 and connected to the second slide block 2522. Therefore, the driving module 2523 can actively drive the second slide block 2522 to move up and down vertically.

[0076] Reference Figure 3 and Figure 5 The second slide block 2522 has a second drive hole 2524 on the side facing the combined roller 21. One end of the combined roller 21 is inserted into the second drive hole 2524 and the combined roller 21 is rotatably connected to the inner wall of the second drive hole 2524. Therefore, the setting of the second drive hole 2524 can realize the connection between the second slide block 2522 and the combined roller 21, and can also ensure the rotation of the combined roller 21 itself. At the same time, it is also convenient for the combined roller 21 to be disassembled from the second slide block 2522.

[0077] Therefore, by cooperating with the first drive member 251 and the second drive member 252, the vertical position of the combined roller 21 can be adjusted.

[0078] Reference Figure 5 and Figure 6 The combined roller 21 includes a main shaft 211, with a fixed disk 212 and a movable disk 214 respectively provided at both ends of the main shaft 211. The fixed disk 212, the movable disk 214 and the main shaft 211 are all coaxially arranged.

[0079] Reference Figure 3 and Figure 4 The fixed disk 212 is fixedly connected to the main shaft 211 on one side of the axis, and a connecting shaft 213 is coaxially connected on the other side. The connecting shaft 213 is inserted into the first drive hole 2517 and is rotatably connected to the inner wall of the first drive hole 2517. Therefore, the setting of the connecting shaft 213 can realize the connection between the main shaft 211 and the first drive component 251.

[0080] Reference Figure 4 and Figure 5 A movable hole 2141 is provided through one axial side of the movable disk 214. The main shaft 211 is inserted into the movable hole 2141 along its own axial direction, and the main shaft 211 is rotatably connected to the inner wall of the movable hole 2141. A positioning sleeve 215 is coaxially connected to the side of the movable disk 214 away from the fixed disk 212. The positioning sleeve 215 is sleeved on the outside of the main shaft 211, and the positioning sleeve 215 is slidably connected to the main shaft 211 along its own axial direction. One end of the positioning sleeve 215 is fixedly connected to the movable disk 214.

[0081] Reference Figure 4 and Figure 5A fixing member 216 is provided between the positioning sleeve 215 and the main shaft 211. The fixing member 216 includes a first positioning hole 2161, which is formed on the outer wall of the positioning sleeve 215 and penetrates through the positioning sleeve 215. A second positioning hole 2162 is formed on the side wall of the main shaft 211. When the positioning sleeve 215 is inserted into the main shaft 211, the first positioning hole 2161 and the second positioning hole 2162 are coaxially connected. A positioning bolt 2163 is inserted into the first positioning hole 2161 and engages with the second positioning hole 2162. The positioning bolt 2163 is threadedly connected to the inner wall of the second positioning hole 2162. Therefore, the movable plate 214 can be detached from the main shaft 211.

[0082] Reference Figure 4 and Figure 5 The positioning sleeve 215 is inserted into the second drive hole 2524 along its own axial direction, and the positioning sleeve 215 is rotatably connected to the inner wall of the second drive hole 2524, and the positioning sleeve 215 is also slidably connected to the inner wall of the second drive hole 2524 along its own axial direction. Therefore, the positioning sleeve 215 can realize the connection between the main shaft 211 and the second drive component 252.

[0083] Reference Figure 6 The main shaft 211 has several rolling wheels 3 arranged along its own axial direction. The rolling wheels 3 are coaxial with the main shaft 211 and are spaced apart sequentially along the axial direction of the main shaft 211. The rolling wheels 3 are located between the fixed disk 212 and the movable disk 214 along the axial direction of the main shaft 211. The fixed disk 212 and the movable disk 214 have the same diameter, which is smaller than the diameter of the rolling wheels 3. Therefore, the anti-counterfeiting labels passing between the combined roller 21 and the auxiliary roller 22 can be conveyed by the rolling wheels 3.

[0084] Reference Figure 6 and Figure 7 An adjustment assembly 31 is provided on the rolling wheel 3. The adjustment assembly 31 includes an adjustment hole 311, which is located on one axial side of the rolling wheel 3 and extends through the rolling wheel 3. The adjustment hole 311 is coaxially arranged with the rolling wheel 3. The main shaft 211 is inserted into the adjustment hole 311 along its own axial direction and is slidably connected to the inner wall of the adjustment hole 311 along its own axial direction. Therefore, the position of the rolling wheel 3 can be adjusted along the length direction of the main shaft 211.

[0085] Reference Figure 6 and Figure 7The rolling wheel 3 is also equipped with a locking assembly 32, which includes several locking screws 321. The axial direction of the locking screws 321 is parallel to the axial direction of the main shaft 211. The locking screws 321 are arranged at intervals along the circumference of the main shaft 211. One end of the locking screw 321 is fixedly connected to the fixed disk 212. The movable disk 214 has a rod insertion hole 322 on the side facing the fixed disk 212. The rod insertion hole 322 is arranged one-to-one with the locking screw 321. The locking screw 321 is inserted into the rod insertion hole 322 along its own axial direction and is also slidably connected to the inner wall of the rod insertion hole 322 along its own axial direction. Therefore, the locking screw 321 and the movable disk 214 can be detachably connected.

[0086] Reference Figure 7 and Figure 8 The rolling wheel 3 has several locking holes 323 extending along its own axial direction. Each locking hole 323 corresponds to a locking screw 321. The locking screw 321 is inserted into the corresponding locking hole 323 along its own axial direction, and the locking screw 321 is also slidably connected to the inner wall of the corresponding locking hole 323 along its own axial direction. Therefore, the setting of the locking holes 323 can ensure that the rolling wheel 3 can be adjusted in position on the main shaft 211 along its own axial direction.

[0087] Reference Figure 6 and Figure 7 The rolling wheel 3 is provided with several nut sets 324, each nut set 324 including a first nut 3241 and a second nut 3242. The first nut 3241 and the second nut 3242 are coaxially arranged and located on opposite sides of the rolling wheel 3. Each nut set 324 corresponds to a locking screw 321, and both the first nut 3241 and the second nut 3242 are threadedly connected to their respective locking screws 321. The rolling wheel 3 is located between the first nut 3241 and the second nut 3242. Therefore, the nut sets 324 can fix the position of the rolling wheel 3.

[0088] Reference Figure 6 and Figure 7 The rolling wheel 3 includes a first wheel cover 33 and a second wheel cover 34, which are coaxially arranged and detachably connected by bolts.

[0089] Reference Figure 7 and Figure 8A sliding annular groove 35 is formed between the first wheel cover 33 and the second wheel cover 34, and the sliding annular groove 35 is coaxially arranged with the first wheel cover 33. A plurality of abutment blocks 36 are provided on the outer side of the first wheel cover 33, and the abutment blocks 36 are evenly spaced along the circumference of the first wheel cover 33. A sliding block 312 is provided on the side of the abutment block 36 facing the first wheel cover 33. The sliding block 312 is inserted into the sliding annular groove 35 and slides along the circumference of the first wheel cover 33 against the inner wall of the sliding annular groove 35. Therefore, the position of the abutment block 36 can be adjusted along the circumference of the rolling wheel 3.

[0090] Reference Figure 7 and Figure 8 The first wheel cover 33 has several first holes 313 extending through its circumference, and these first holes 313 are evenly spaced along the circumference of the first wheel cover 33. The sliding block 312 has a second hole 314 extending through its axial direction along the main shaft 211. The second wheel cover 34 has several third holes 315 extending through its axial direction, and each third hole 315 corresponds to one of the first holes 313, and the third hole 315 communicates with the corresponding first hole 313 along its own axial direction.

[0091] Reference Figure 7 and Figure 8 There is a second hole 314 that is connected to the corresponding first hole 313 and the corresponding third hole 315. An adjusting bolt 316 is inserted into the corresponding first hole 313. The adjusting bolt 316 passes through the second hole 314 and the third hole 315 at the same time, so that the position of the abutment block 36 can be fixed.

[0092] Reference Figure 7 and Figure 9 The rolling wheel 3 is also provided with several abutting rods 4, which are arranged sequentially at intervals along the circumference of the rolling wheel 3. The length direction of the abutting rods 4 is parallel to the axial direction of the main shaft 211. The abutting rods 4 are arranged in a one-to-one correspondence with the abutting blocks 36. A connecting groove 41 is opened on the side of the abutting rod 4 facing the rolling wheel 3. The connecting groove 41 passes through both ends of the abutting rod 4 along the length direction of the abutting rod 4. The connecting groove 41 of the abutting rod 4 is inserted and engaged with the corresponding abutting blocks 36 sequentially along the length direction of the abutting rod 4. The two ends of the abutting rod 4 abut against the movable disk 214 and the fixed disk 212 respectively.

[0093] Therefore, the setting of the long rod 4 can increase the contact area between the combined roller 21 and the anti-counterfeiting label, thereby facilitating a more stable conveying of the anti-counterfeiting label.

[0094] The implementation principle of this application embodiment is as follows: Before using the screen printing device, firstly, the distance between the rollers 3 and the distance between the contact blocks 36 on the rollers 3 are adjusted by adjusting component 31. Then, the rollers 3 are fixed by locking component 32. After that, the contact rod 4 is installed on the outside of the rollers 3. Finally, the movable plate 214 is assembled and the position of the combined roller 21 in the vertical direction is adjusted so that the interval between the combined roller 21 and the auxiliary roller 22 can meet the requirements of anti-counterfeiting label conveying.

[0095] When the length of the silver coating of the anti-counterfeiting label roll is set along the width of the anti-counterfeiting label roll, the applicable abutment rod 4 can increase the conveying stability of the anti-counterfeiting label.

[0096] When the length of the silver coating of the anti-counterfeiting label roll is set along the length of the anti-counterfeiting label roll, the abutment rod 4 is removed, and the abutment block 36 on the roller 3 is used to transport the anti-counterfeiting label, thereby increasing the transport stability of the anti-counterfeiting label.

[0097] In summary, the screen printing equipment of this application can meet the printing requirements of silver coating on different anti-counterfeiting labels.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
