Description

TECHNICAL FIELD

[0001] The present application relates to the field of label code spraying, in particular to a label automatic code spraying device. BACKGROUND

[0002] Commodity labels are one of the ways to identify product information. They are classified according to different industries, materials, etc. For example, clothing hang tag labels, agricultural product labels, beverage labels, fruit labels, vegetable labels, logistics labels, and anti-counterfeit labels that we encounter in our daily life. In order to print relevant product information on the labels, label automatic code spraying devices are often used.

[0003] In related technologies, a label code spraying mechanism for a label code spraying machine is disclosed in Chinese Patent No. CN215321509U. The mechanism includes a base plate, a code spraying machine body disposed on the base plate, a nozzle disposed on one side of the code spraying machine body, and a support frame that fixes the nozzle to the base plate. During operation, the workpiece to be sprayed is placed in front of the nozzle, and the nozzle is turned on to spray the workpiece. When spraying a large number of workpieces in the same batch, the workpieces are continuously replaced and the nozzle is aimed at the workpieces. However, the workpieces are prone to move during spraying, resulting in low spraying accuracy. Therefore, improvements are needed. SUMMARY

[0004] To improve the problem of workpiece movement during spraying and low spraying accuracy, the present application provides a label automatic code spraying device.

[0005] The label automatic code spraying device provided by the present application adopts the following technical solution:

[0006] A label automatic code spraying device includes:

[0007] A workbench;

[0008] A transmission conveyor belt is rotatably connected to the workbench and is used to transport labels to be sprayed.

[0009] A receiving table is provided on the workbench and located at one end of the length direction of the transmission conveyor belt.

[0010] A driving assembly is provided on the workbench to drive the transmission conveyor belt to rotate and transport the labels to be sprayed to the receiving table.

[0011] A positioning plate is provided on the workbench and is driven by a positioning driving member to fix the labels to be sprayed on the receiving table.

[0012] A positioning driving member is provided on the workbench, and the output end of the positioning driving member is fixed to the positioning plate to drive the positioning plate to move along the width direction of the workbench.

[0013] The inkjet printer is arranged on one side of the workbench, and the inkjet printer is connected with a nozzle. The nozzle is arranged on the workbench and used for inkjet printing on the label on the supporting table.

[0014] By adopting the above technical scheme, when the label to be inkjet printed is placed on the transmission conveying belt and arranged in sequence along the length direction of the transmission conveying belt, the driving assembly is started to drive the transmission conveying belt to rotate, thereby driving the label to be inkjet printed to move to the supporting table. Then, the position of the positioning driving part on the workbench is adjusted, and then the positioning driving part is started to drive the positioning plate to abut against the side wall arranged along the width direction of the supporting table, thereby limiting the movement of the label on the supporting table, i.e. fixing the label on the supporting table. Then, the nozzle is opened to perform inkjet printing on the label to be inkjet printed on the supporting table. In this process, the position of the nozzle is fixed, and the label is limited by the positioning plate and is not easy to move, thereby improving the accuracy of inkjet printing of the nozzle on the label.

[0015] Optionally, the driving assembly comprises:

[0016] The rotating wheel is vertically arranged and rotationally connected to the workbench, and the rotating wheel is located above the transmission conveying belt.

[0017] The motor is arranged on the workbench, the output end of the motor is coaxially fixed with the rotating wheel, and the motor is used for driving the rotating wheel to rotate.

[0018] The pushing rod is slidingly connected to the rotating wheel and moves along the diameter direction of the rotating wheel. The top wall of the transmission conveying belt is provided with a plurality of pushing holes. The pushing holes are arranged along the length direction of the transmission conveying belt. The pushing holes are used for determining the position of the label on the transmission conveying belt. The pushing rod is inserted into the pushing hole and used for pushing the transmission conveying belt to rotate and limiting the deviation of the transmission conveying belt.

[0019] The pushing spring is arranged on the rotating wheel and used for pushing the pushing rod away from the center of the rotating wheel.

[0020] By adopting the above technical scheme, when the label to be inkjet printed is placed on the transmission conveying belt, the label can be placed in sequence in alignment with the pushing hole, thereby facilitating the determination of the position of the label. The motor is started to drive the rotating wheel to rotate, so that the pushing rod rotates around the center of the rotating wheel. In this process, the end of the pushing rod away from the center of the rotating wheel first abuts against the transmission conveying belt. The pushing rod pushes the pushing spring to move to the center of the rotating wheel. At the same time, the pushing rod also slides on the conveying belt under the driving of the rotating wheel, until the pushing rod moves to the pushing hole. The pushing rod is inserted into the pushing hole under the pushing of the pushing spring, the side wall of the pushing rod abuts against the inner wall of the pushing hole, and the rotating wheel continues to drive the pushing rod to move, thereby driving the pushing rod to move the transmission conveying belt and conveying the label on the transmission conveying belt to the supporting table.

[0021] And the rotating wheel is still rotating, when the distance between the propelling spring and the propelling hole is greater than the length of the propelling rod, the propelling rod is pulled out of the propelling hole, so that the transmission belt stops moving. In the process of starting the motor, the propelling rod repeatedly performs the above steps, that is, the propelling rod is inserted into the next propelling hole, and the transmission belt is pushed to move again. The label corresponds to the propelling hole, and the intermittent movement of the transmission belt is realized, and then the labels on the transmission belt are placed on the receiving table in turn.

[0022] Optionally, a rotating assembly for driving the receiving table to rotate is arranged on the working frame, and the rotating assembly comprises:

[0023] A rotating rod is vertically arranged, the top end of the rotating rod is coaxially fixed with the bottom of the receiving table, a positioning rod is vertically fixed on the working frame, the bottom end of the rotating rod is sleeved on the positioning rod and rotates on the positioning rod, a rotating groove is formed in the side wall of the rotating rod, and a sliding groove is formed in the side wall of the rotating rod in the vertical direction, the top end of the sliding groove is communicated with the top end of the rotating groove;

[0024] A sliding block is fixed on the working frame, the sliding block is inserted into the rotating groove, when the rotating rod rotates, the sliding block moves in the rotating groove to drive the rotating rod to move up and down, and the sliding block is inserted into the sliding groove and moves in the sliding groove.

[0025] A supporting spring is arranged at the bottom of the rotating rod and used for pushing the rotating rod upward.

[0026] By adopting the above technical scheme, when the label is conveyed to the receiving table by the transmission belt, the positioning plate is first separated from the side wall of the label by using the positioning driving element, and then the rotating rod is driven to rotate, that is, the rotating rod rotates on the positioning rod with the central axis of the positioning rod as the axis, at the same time, the inner wall of the rotating groove slides on the side wall of the sliding block, and the sliding block is fixed, so that the rotating rod rotates and also moves downward spirally, that is, the receiving table rotates in the gap between the receiving table and the transmission belt first, when the receiving table rotates to the limit position in the gap, the downward movement distance of the receiving table is just equal to the thickness of the receiving table, so that the receiving table is located below the transmission belt as a whole, and the receiving table can continue to rotate below the transmission belt, so that the transmission belt does not interfere with the rotation of the receiving table.

[0027] When the sliding block moves to the top end of the rotating groove, i.e. is located at the top end of the sliding groove, the receiving table rotates 90° below the conveying belt, realizing the change of the angle of the label on the receiving table. In the process of moving down, the receiving table continuously extrudes the supporting spring downward, and the sliding block abuts against the inner wall of the rotating groove, limiting the supporting spring from pushing the rotating rod upward. However, at this time, the sliding block is located at the top end of the sliding groove, and the supporting spring loses the limitation and pushes the rotating rod upward, i.e. the sliding block moves downward relative to the sliding groove until the bottom wall of the sliding groove abuts against the sliding block. At this time, the receiving table returns to the initial state of the highest point.

[0028] Then the sliding positioning drive member is adjusted to the distance of the receiving table, and the positioning drive member is started again, so that the positioning plate abuts against both sides of the label arranged along the length direction of the receiving table, so that the label is moved and positioned on all sides, realizing the positioning of the label on the receiving table, and increasing the accuracy of the inkjet head in printing the code on the label.

[0029] Optionally, the working frame is provided with a linkage assembly for driving the rotating rod to rotate, and the linkage assembly comprises:

[0030] The incomplete gear is vertically arranged and rotationally connected to the working frame. The incomplete gear is connected to the motor through a linkage transmission belt. One end of the linkage transmission belt is coaxially fixed to the output end of the motor, and the other end is coaxially fixed to the incomplete gear.

[0031] The crown gear is rotationally connected to the working frame. The crown gear is sleeved on the rotating rod. A guide block is fixed to the inner wall of the crown gear. A guide groove is formed in the side wall of the rotating rod in the vertical direction. The guide block is inserted into the guide groove and can move in the guide groove. The crown gear is engaged with the incomplete gear to drive the rotating rod to rotate.

[0032] By adopting the above technical scheme, when the motor is started, the linkage transmission belt is also driven to rotate, so that the incomplete gear rotates. After the positioning plate pushes the label on the receiving table and completes the positioning, the positioning plate is reset, the incomplete gear rotates to engage with the crown gear, the crown gear is driven to rotate, the guide block also rotates, the side wall of the guide block abuts against the inner wall of the guide groove, so as to drive the rotating rod to rotate around the central axis of the rotating rod. In the process of rotating, the rotating rod also moves vertically, so that the inner wall of the guide groove slides on the guide block, realizing the rotation and vertical movement of the rotating rod.

[0033] Optionally, a fixing groove is formed in the working frame in the width direction of the working frame. A fixing bolt is inserted into the fixing groove. One end of the fixing bolt penetrates through the working frame, and the other end is rotationally connected to the inner wall of the fixing groove. A fixing block is fixed to the positioning drive member. The fixing block is sleeved on the fixing bolt. The fixing block is threadedly connected with the fixing bolt. The fixing bolt rotationally drives the fixing block to move in the fixing groove.

[0034] By adopting the technical scheme, the fixed bolt is rotated to move the fixed block in the fixed groove along the width direction of the working frame, so that the distance between the positioning driving member and the receiving table is adjusted to adapt to the limiting of labels of different sizes, and if the position to be sprayed on the label changes, the position of the label on the receiving table moved by the positioning plate can also be changed, so that the position to be sprayed on the label can be aligned with the nozzle, that is, the nozzle can spray on the specified position, thereby improving the accuracy of spraying.

[0035] Optionally, the receiving table comprises:

[0036] The mounting frame is horizontally arranged, and the rotating rod is fixed to the mounting frame.

[0037] A plurality of mounting rollers are arranged on the mounting frame, and the ends of the mounting rollers are rotatably connected to the mounting frame. The plurality of mounting rollers are arranged along the width direction of the mounting frame and uniformly distributed along the length direction of the mounting frame.

[0038] A transmission assembly is arranged on the mounting frame and used to drive the plurality of mounting rollers to rotate synchronously.

[0039] In the initial state, the rotating roller is parallel to the moving direction of the conveying belt, so that when the label is conveyed to the receiving table by the conveying belt, the label will not move on the mounting roller under the driving of the conveying belt, and the mounting roller is driven to rotate, so that the label will not move out of the receiving table. When the positioning of the label on the receiving table is completed, that is, the label is rotated by 90° and the periphery of the label is positioned by the positioning plate, the rotating roller is perpendicular to the moving direction of the conveying belt at this time, and the plurality of mounting rollers are driven to rotate simultaneously by the transmission assembly, so that the label after spraying is conveyed out of the receiving table.

[0040] Optionally, the transmission assembly comprises:

[0041] A plurality of transmission gears are in one-to-one correspondence with the mounting rollers. One end of the mounting roller penetrates through the mounting frame and is fixed coaxially with the transmission gear.

[0042] A transmission rack is slidably connected to the outer side wall of the mounting frame. The transmission rack moves along the length direction of the mounting frame, and the transmission rack is engaged with the transmission gear.

[0043] By adopting the technical scheme, when the label is sprayed on the mounting roller, the transmission rack is driven to move along the length direction of the mounting frame, so that the plurality of transmission gears are driven to rotate synchronously, thereby driving the plurality of mounting rollers to rotate, and the label after spraying is conveyed.

[0044] Optionally, the working frame is provided with a resetting assembly for resetting the receiving table, and the resetting assembly comprises:

[0045] A reset drive is arranged on the workbench;

[0046] A moving block is fixed on the output end of the reset drive, and the reset drive is used to drive the moving block to move along the length direction of the workbench, and a plug hole is arranged on the side of the moving block close to the mounting frame;

[0047] A plug block is inserted into the plug hole and moves in the plug hole towards or away from the mounting frame, a moving groove is arranged on the outer side wall of the mounting frame, and the end of the moving groove away from the conveying belt is arranged to be inclined downward, so that when the plug block is inserted into the moving groove and moves in the moving groove towards the conveying belt, the mounting frame is driven to move downward;

[0048] A mounting spring is arranged in the plug hole and used to push the plug block towards the mounting frame.

[0049] By adopting the above technical scheme, when the label is completed and transported out of the receiving table after the code is sprayed on the receiving table, the bottom end of the moving groove is in the moving direction of the plug block, then the reset drive is started to drive the moving block to move the plug block, when the plug block moves to the bottom end of the moving groove, the mounting spring pushes the plug block to be inserted into the moving groove, then the reset drive drives the plug block to reset, the side wall of the plug block abuts against the inner wall of the moving groove to limit and guide, so that the plug block can only move along the track of the moving groove, and the plug block is limited by the reset drive, and finally the mounting frame moves downward.

[0050] In this process, the sliding block moves in the sliding groove, when the plug block moves to the top end of the moving groove, the sliding block also moves to the top end of the sliding groove, which is also the top end of the rotating groove, at this time the reset drive stops moving, the supporting spring restores the deformation to push the rotating rod upward, that is, the sliding block relatively moves in the rotating groove, so as to realize the spiral upward movement of the mounting frame, and the reset of the receiving table, that is, the mounting roller restores to the state of being flush with the conveying belt. Further, the code spraying work on the next label is realized.

[0051] Optionally, a guide surface is arranged on the side of the plug block away from the conveying belt, and the end of the guide surface away from the mounting spring is arranged to be inclined towards the conveying belt.

[0052] By adopting the above technical scheme, when the rotating rod spirally moves downward with the central axis of the rotating rod as the axis, the inner wall of the moving groove abuts against and presses the guide surface, and the guide surface plays a guiding role. The guide surface slides on the inner wall of the moving groove, so as to press the mounting spring, until the plug block relatively moves out of the moving groove, so that the plug block does not interfere with the rotation of the rotating rod.

[0053] Optionally, the working frame is provided with a reset spring, one end of the reset spring is fixed with the working frame, and the other end is fixed with one end of the transmission rack, which is used to push the transmission rack to the direction close to the transmission conveying belt, the end of the moving block close to the transmission rack is provided with an abutting block, the abutting block abuts with the other end of the transmission rack and drives the transmission rack to move along the length direction of the mounting frame.

[0054] By adopting the technical scheme, when the reset driving part starts, the moving block is driven to push and move, the abutting block abuts with one end of the transmission rack, and the transmission rack is pushed to move to the direction away from the transmission conveying belt, the reset spring is compressed, the rotation of the mounting roller is realized, and then the transportation of the label after code spraying is realized. When the plug block moves to the bottom end of the moving groove and is inserted into the moving groove, the reset driving part drives the moving block to reset, so that the plug block moves relatively in the moving groove, the reset of the receiving table is realized, and at this time, the transmission rack is reset under the action of the reset spring, which is convenient for next movement.

[0055] In summary, the present application has at least one of the following beneficial effects:

[0056] 1. The label to be sprayed is placed on the transmission conveying belt and is arranged in sequence along the length direction of the transmission conveying belt, then the driving assembly is started to drive the transmission conveying belt to rotate, so as to drive the label to be sprayed to move to the receiving table, then the position of the positioning driving part on the working frame is adjusted, then the positioning driving part is started to drive the positioning plate to abut with the side wall of the label arranged along the width direction of the receiving table, so as to limit the movement of the label on the receiving table, that is, the label is fixed on the receiving table, so that the accuracy of the code spraying of the nozzle to the label is higher.

[0070] With reference to Figure 1 and Figure 3 , the pushing rod 43 is located on the end face of the rotating wheel 41, the pushing rod 43 is fixed with a sliding block, the end face of the rotating wheel 41 is provided with a sliding groove in the diameter direction, the sliding block is inserted into the sliding groove and can move in the sliding groove, the pushing spring 44 is arranged in the sliding groove, one end of the pushing spring 44 is fixed with the inner wall of the sliding groove, and the other end is fixed with the end of the pushing rod 43 close to the center of the rotating wheel 41, and the transmission conveyor belt 20 is provided with a plurality of pushing holes 21, which are uniformly arranged along the length direction of the transmission conveyor belt 20.

[0071] When the labels to be coded are placed on the transmission conveyor belt 20, they can be placed in sequence in alignment with the pushing holes 21, which facilitates the determination of the position of the labels, the motor 42 is started to drive the rotating wheel 41 to rotate, so that the pushing rod 43 rotates with the center of the rotating wheel 41 as the axis, in this process, the end of the pushing rod 43 away from the center of the rotating wheel 41 first abuts against the transmission conveyor belt 20, the pushing rod 43 pushes the pushing spring 44 to move towards the center of the rotating wheel 41, at the same time, the pushing rod 43 also slides on the conveyor belt under the driving of the rotating wheel 41, until the pushing rod 43 moves to the pushing hole 21. The pushing rod 43 is inserted into the pushing hole 21 under the pushing of the pushing spring 44, the side wall of the pushing rod 43 abuts against the inner wall of the pushing hole 21, and the rotating wheel 41 continues to drive the pushing rod 43 to move, so that the pushing rod 43 pushes the transmission conveyor belt 20 to move, and the labels on the transmission conveyor belt 20 are transported to the receiving table 30.

[0072] And the rotating wheel 41 is still in rotation, when the distance between the push spring 44 and the push hole 21 is greater than the length of the push rod 43, so that the push rod 43 is extracted from the push hole 21, so that the transmission conveyor belt 20 stops moving. In the process of starting the motor 42, the push rod 43 repeatedly above steps, that is, the push rod 43 is inserted into the next push hole 21, and the transmission conveyor belt 20 is moved again, realizing the intermittent movement of the transmission conveyor belt 20, and the label is one-to-one corresponding to the push hole 31, and then the label on the transmission conveyor belt 20 is placed on the receiving table 30 in turn.

[0073] With reference to Figure 1 And Figure 4 In order to increase the accuracy of the label on the receiving table 30, that is, to prevent the label from moving on the receiving table 30, two positioning driving members 90 are arranged on the working frame 10. In the embodiment of the application, the positioning driving member 90 adopts an electric push rod, both of the positioning driving members 90 are arranged along the width direction of the working frame 10, and the output ends of the positioning driving members 90 are both fixed with positioning plates 80.

The bottom wall of the positioning plate 80 is on the same horizontal plane as the top wall of the receiving table 30.

[0074] With reference to Figure 4 A fixed block 91 is fixed on the bottom wall of the positioning driving member 90. A fixed groove 11 is arranged on the working frame 10 along the width direction of the working frame 10. The fixed block 91 is inserted into the fixed groove 11 and can move in the fixed groove 11. A fixed bolt 110 is inserted into the fixed groove 11.

The fixed bolt 110 penetrates through the fixed block 91 and is threadedly connected with the fixed block 91.

[0075] Before the label on the receiving table 30 is coded, the fixed bolt 110 is rotated to move the fixed block 91 in the fixed groove 11 along the width direction of the working frame 10, that is, the distance between the positioning driving member 90 and the receiving table 30 can be adjusted to adapt to the positioning of labels of different sizes. At the same time, if the position of the label to be coded changes, the position of the label pushed by the positioning plate 80 on the receiving table 30 can also be changed so that the position of the label to be coded can be aligned with the nozzle 121. Then the nozzle 121 is started to code the label. At this time, the relatively two sides of the label are clamped and fixed by the positioning plate 80 and will not move, so that the coding accuracy is higher.

[0076] With reference to Figure 1 And Figure 5In order to enable the label to be positioned on the receiving table 30, that is, the label can be adjusted and moved in all directions, and to increase the accuracy of the position of the label to be sprayed on the label to the alignment of the spray head 121, a rotating assembly 50 is arranged on the working frame 10, and the rotating assembly 50 is used to drive the receiving table 30 to rotate. The rotating assembly 50 comprises a rotating rod 51, a sliding block 52 and a supporting spring 53. The rotating rod 51 is vertically arranged, and the top end of the rotating rod 51 is fixed to the bottom wall of the receiving table 30. A positioning rod 130 is vertically fixed to the bottom wall of the working frame 10, and the bottom end of the rotating rod 51 is coaxially inserted into the positioning rod 130. The rotating rod 51 can rotate around the central axis of the rotating rod 51 on the positioning rod 130, and can also move vertically on the positioning rod 130.

After the label is conveyed to the receiving table 30 by the conveying belt 20, the positioning plate 80 is first driven by the positioning driving part 90 to abut against the side wall of the label and then separate. At this time, the distance between the side wall of the label and the side wall of the receiving table 30 in the width direction is adjusted, that is, the position of the label in the width direction of the receiving table 30 is positioned. Then the rotating rod 51 is driven to rotate, that is, the rotating rod 51 rotates around the central axis of the positioning rod 130 on the positioning rod 130. At the same time, the inner wall of the rotating groove 511 slides on the side wall of the sliding block 52, while the sliding block 52 is fixed, so that the rotating rod 51 rotates and also moves downward in a spiral, that is, the receiving table 30 first rotates in the gap between the receiving table 30 and the conveying belt 20. When the receiving table 30 rotates to the limit position in the gap, the distance of the downward movement of the receiving table 30 is just equal to the thickness of the receiving table 30, so that the receiving table 30 is located below the conveying belt 20 as a whole, and the receiving table 30 can continue to rotate below the conveying belt 20, so that the conveying belt 20 does not interfere with the rotation of the receiving table 30.

[0079] When the sliding block 52 moves to the top of the rotating groove 511, i.e. to the top of the sliding groove 512, the receiving table 30 rotates 90° below the conveying belt 20, and the label on the receiving table 30 is aligned with the positioning plate 80 on the other two sides. During the downward movement of the receiving table 30, the supporting spring 53 is continuously pressed downward, and the sliding block 52 abuts against the inner wall of the rotating groove 511, limiting the supporting spring 53 from pushing the rotating rod 51 upward. However, at this time, the sliding block 52 is located at the top of the sliding groove 512, and the supporting spring 53 loses the limitation and pushes the rotating rod 51 upward, i.e. the sliding block 52 moves downward in the sliding groove 512 until the bottom wall of the sliding groove 512 abuts against the sliding block 52. At this time, the receiving table 30 returns to the highest point of the initial state.

[0080] Then, the fixed bolt 110 is rotated to adjust the distance between the positioning driving member 90 and the receiving table, and the positioning driving member 90 is started again, so that the positioning plate 80 abuts against the two sides of the label arranged along the length direction of the receiving table 30, thereby moving and limiting the four sides of the label, achieving the positioning of the label on the receiving table 30, and increasing the accuracy of the label code sprayed by the nozzle 121.

[0081] Referring to Figure 2 and Figure 6 , in order to drive the rotating rod 51 to rotate, the linkage assembly 60 is arranged on the working frame 10, and the linkage assembly 60 includes an incomplete gear 61 and a crown gear 62. The incomplete gear 61 is vertically arranged and rotationally connected to the working frame 10. The motor 42 is connected to the incomplete gear 61 through a linkage transmission belt 611. The output end of the motor 42 is coaxially fixed to the driving wheel of the linkage transmission belt 611, and the driven wheel of the linkage transmission belt 611 is coaxially fixed to the incomplete gear 61.

[0082] Referring to Figure 2 and Figure 6 , the crown gear 62 is horizontally arranged and rotationally connected to the working frame 10. The crown gear 62 is sleeved on the rotating rod 51 and coaxial with the rotating rod 51. The inner wall of the crown gear 62 is integrally formed with a guide block 621, and the sidewall of the rotating rod 51 is provided with a guide groove 513 in the vertical direction. The guide block 621 is inserted into the guide groove 513 and can move in the guide groove 513. The crown gear 62 is engaged with the incomplete gear 61.

[0083] The motor 42 is started, and the linkage transmission belt 611 is also driven to rotate, so that the incomplete gear 61 rotates. When the positioning plate 80 pushes the label on the receiving table 30 and positioning is completed, the positioning plate 80 is reset, the incomplete gear 61 rotates to mesh with the crown gear 62, drives the crown gear 62 to rotate, so that the guide block 621 also rotates, the side wall of the guide block 621 abuts against the inner wall of the guide groove 513, thereby driving the rotating rod 51 to rotate about the central axis of the rotating rod 51. In the rotating process, the rotating rod 51 also moves vertically, so that the inner wall of the guide groove 513 slides on the guide block 621, and the rotating rod 51 rotates and moves up and down.

[0084] With reference to Figure 5 In order to facilitate the label on the receiving table 30 after the code is sprayed to be transported out of the receiving table 30, the receiving table 30 comprises a mounting frame 31 and a plurality of mounting rollers 32. The mounting frame 31 is horizontally arranged, and the bottom wall of the mounting frame 31 is fixed to the top wall of the rotating rod 51. The plurality of mounting rollers 32 are arranged in the mounting frame 31. The mounting rollers 32 are horizontally arranged and rotatably connected to the mounting frame 31 at the ends. The top end of the mounting roller 32 is on the same horizontal plane as the transmission belt 20. The plurality of mounting rollers 32 are arranged along the width direction of the mounting frame 31 and uniformly distributed along the length direction of the mounting frame 31.

[0085] In the initial state, the rotating roller is parallel to the moving direction of the transmission belt 20. That is, when the transmission belt 20 transports the label to the receiving table 30, the label will not move on the mounting roller 32 under the driving of the transmission belt 20, and the mounting roller 32 is driven to rotate, so that the label will not move out of the receiving table 30. When the label is positioned on the receiving table 30, that is, the label rotates 90°, the label is positioned by the positioning plate 80 around the label. At this time, the rotating roller is perpendicular to the moving direction of the transmission belt 20. Then, the plurality of mounting rollers 32 are driven to rotate at the same time, so that the label after the code is sprayed is transported out of the receiving table 30. In order to facilitate the label transported out of the receiving table 30, a transportation belt is rotatably connected to the workbench 10. The transportation belt is arranged along the length direction of the workbench 10 and used to transport the label after the code is sprayed.

[0086] With reference to Figure 5 and Figure 7The receiving table 30 further comprises a transmission assembly 33 for driving the mounting rollers 32 to rotate synchronously, the transmission assembly 33 comprising a transmission rack 332 and a plurality of transmission gears 331, the transmission gears 331 corresponding to the mounting rollers 32 one by one, and one end of the mounting rollers 32 penetrating through the mounting frame 31 and fixed coaxially with the transmission gears 331. The transmission rack 332 is arranged along the length direction of the receiving table 30, wherein the length direction of the mounting frame 31 is the length direction of the whole receiving table 30. The transmission rack 332 is engaged with the transmission gears 331, and the side wall of the transmission rack 332 is fixed with a positioning block, and the side wall of the mounting frame 31 is provided with a positioning groove, the positioning groove being arranged along the length direction of the mounting frame 31, and the positioning block is inserted into the positioning groove and can move in the positioning groove.

[0087] When the label is completed with the code spraying on the mounting rollers 32, the transmission rack 332 is driven to move, so that the positioning block moves in the positioning groove, i.e. the transmission rack 332 moves along the length direction of the mounting frame 31, thereby driving the plurality of transmission gears 331 to rotate synchronously, driving the plurality of mounting rollers 32 to rotate simultaneously, and further realizing the transportation of the label completed with the code spraying.

[0088] Referring to Figure 5 and Figure 7 , in order to limit the transmission rack 332 from moving out of the mounting frame 31 completely, and in order to enable the transmission rack 332 to reset quickly, a reset spring 3321 is fixed on the side wall of the mounting frame 31, one end of the reset spring 3321 being fixed with the working stand 10, and the other end being fixed with one end of the transmission rack 332.

[0089] Referring to Figure 5 and Figure 7 , when the label completed with the code spraying on the receiving table 30 is transported completely, in order to enable the receiving table 30 to reset to receive the next label for code spraying, a reset assembly 70 is arranged on the working stand 10, the reset assembly 70 comprising a reset driving member 71, a moving block 72, an insertion block 73 and a mounting spring 74, the reset driving member 71 being fixed on the working stand 10, in the embodiment of the application, the reset driving member 71 adopting a pneumatic cylinder, the moving block 72 being fixed on the output end of the reset driving member 71, the reset driving member 71 being used to drive the moving block 72 to move along the length direction of the working stand 10, the side of the moving block 72 close to the mounting frame 31 being provided with an insertion hole 721, the insertion block 73 being inserted into the insertion hole 721 and being movable in the insertion hole 721, the mounting spring 74 being inserted into the insertion hole 721, and one end of the mounting spring 74 being fixed with the inner wall of the insertion hole 721, and the other end being fixed with the insertion block 73.

[0090] Referring to Figure 1 and Figure 7The side wall of the mounting frame 31 is fixed with a moving plate, the moving plate is provided with a moving slot 311, the moving slot 311 is inclined downward away from one end of the transmission conveying belt 20, the insertion block 73 can be inserted in the moving slot 311 and can move in the moving slot 311, the insertion block 73 is provided with a guide surface 731 away from one end of the mounting spring 74, the guide surface 731 is inclined to the direction of the transmission conveying belt 20.

[0091] When the label is completed and transported out of the receiving table 30, the bottom end of the moving slot 311 is in the moving direction of the insertion block 73, then the reset driving part 71 is started, drives the moving block 72 to move the insertion block 73, when the insertion block 73 moves to the bottom end of the moving slot 311, the mounting spring 74 pushes the insertion block 73 to be inserted into the moving slot 311, then the reset driving part 71 resets the insertion block 73, the side wall of the insertion block 73 abuts against the inner wall of the moving slot 311, which limits the guide, so that the insertion block 73 can only move along the track of the moving slot 311, and the insertion block 73 is limited by the reset driving part 71, finally the mounting frame 31 moves downward.

[0092] In this process, the sliding block 52 moves in the sliding slot 512, when the insertion block 73 moves to the top end of the moving slot 311, the sliding block 52 also moves to the top end of the sliding slot 512, which is also the top end of the rotating slot 511, at this time the reset driving part 71 stops moving, the supporting spring 53 restores the deformation, pushes the rotating rod 51 upward, that is, the sliding block 52 moves relatively in the rotating slot 511, so as to realize the spiral upward movement of the mounting frame 31, and the reset of the receiving table 30, in this process, the guide surface 731 slides on the inner wall of the moving slot 311, so as to press the mounting spring 74, until the insertion block 73 relatively separates from the moving slot 311, so that the insertion block 73 does not interfere with the rotation of the rotating rod 51. Finally, the mounting roller 32 restores to the state of being flush with the transmission conveying belt 20. Further, the next label is realized for the code printing work.

[0093] The implementation principle of the label automatic code spraying device is as follows: during work, the labels to be sprayed are placed on the transmission conveying belt 20 and are arranged in sequence along the length direction of the transmission conveying belt 20, then the driving assembly 40 is started to drive the transmission conveying belt 20 to rotate, thereby driving the labels to be sprayed to move to the receiving table 30, then the position of the positioning driving part 90 on the working frame 10 is adjusted, then the positioning driving part 90 is started to drive the positioning plate 80 to abut against the side wall of the label arranged along the width direction of the receiving table 30, thereby limiting the movement of the label on the receiving table 30, that is, the label is fixed on the receiving table 30, then the nozzle 121 is opened to spray the label on the receiving table 30, during the process, the nozzle 121 is fixed in position, and the label is not easy to move due to the limitation of the positioning plate 80, thereby the accuracy of the nozzle 121 spraying the label is high.
