Abstract
Description
Technical Field
[0001] This application relates to the technical field of irregularly shaped mat processing, and in particular to a precision digital automatic spraying equipment and its construction process for irregularly shaped mat production lines. Background Technology
[0002] In the production of sanitary napkins, panty liners, and other similar products, the precise and uniform spraying of chemicals onto their surfaces is a crucial step. The quality of this step directly determines the comfort, functionality, and consistency of the finished product.
[0003] Currently, automated spraying equipment has been widely adopted in the production lines of these hygiene and care products to replace the earlier, inefficient, and unstable manual spraying methods. The basic workflow of the automated spraying equipment is as follows: the conveyor module transports the irregularly shaped pads sequentially to the preset spraying stations, and then the spraying module starts to spray the irregularly shaped pads with the chemical solution.
[0004] However, in actual production, existing automated spraying equipment still has a significant technical flaw. Due to uneven material feeding, overlapping of individual irregularly shaped pads during conveying, or intermittent supply of raw materials, the designated pad-bearing positions on the conveyor belt may not actually be supporting the pads, resulting in a material shortage. In existing equipment, even if a station is short of material, the spraying program will still start as usual, causing the spray solution to be sprayed directly onto the empty conveyor belt. This wastes the spray solution and increases production costs; furthermore, the sprayed solution contaminates the equipment surface, potentially requiring frequent shutdowns for cleaning and impacting overall production efficiency. Summary of the Invention
[0005] In order to accurately control the spraying action at the spraying station and reduce the waste of chemical solution and equipment pollution, this application provides a precision digital automatic chemical spraying equipment and its construction process for irregularly shaped pad production lines.
[0006] On the one hand, this application provides a precision digital automatic spraying equipment for irregularly shaped pad production lines, which adopts the following technical solution, including: frame, The conveying mechanism includes a spray liquid conveying line and a discharge conveying line mounted on the frame; The feeding mechanism includes a hopper and a feeding module. The hopper is located at one end of the spray liquid transmission line. The hopper is provided with multiple inclined storage channels. The feeding module is used to transfer the irregularly shaped pads in the storage channels one by one to the spray liquid transmission line. The liquid spraying mechanism includes a control module, a spraying module, and a material shortage detection unit. The spraying module includes a spraying bracket and an infusion pump. The spraying bracket is positioned above the liquid transmission line. Multiple infusion pumps are spaced apart on the spraying bracket, and each infusion pump is connected to a sprayer. The outlet end of the sprayer faces the liquid transmission line. Each infusion pump corresponds to a material storage tank. The material shortage detection unit is positioned on the side of the spraying bracket near the material hopper, and multiple material shortage detection units are provided corresponding to the infusion pumps. Both the material shortage detection unit and the infusion pumps are electrically connected to the control module.
[0007] By adopting the above technical solution, after the equipment starts up, the spraying liquid transmission line carries the irregularly shaped pads. When the irregularly shaped pads pass under the material shortage detection unit, each detection unit checks whether there are irregularly shaped pads at its corresponding station and transmits the detection signal to the control module in real time. The control module makes a judgment based on the received signal: if a station detects that there is material, it controls the corresponding infusion pump to start in the next sequence, and performs precise spraying through the sprayer; if a station detects that there is a material shortage, it controls the corresponding infusion pump to remain in the off state to avoid dry spraying. This solves the problems of liquid waste and equipment contamination, significantly reduces production costs, and reduces the frequency of cleaning and maintenance.
[0008] Optionally, a material separation module is provided at one end of the hopper near the pesticide transmission line. The material separation module includes a material separation plate and a driving unit. A material separation port is provided on the bottom wall of the storage channel. The material separation plate is slidably provided at each of the material separation ports. The driving unit is used to drive the material separation plate to slide. The feeding module includes a transfer plate, a negative pressure source, and a rotation source. The transfer plate is rotatably positioned above the spray liquid transmission line, and the rotation source drives the transfer plate to rotate. The transfer plate has multiple sets of adsorption holes, each of which corresponds to a storage channel. The negative pressure source is connected to each of the adsorption hole sets.
[0009] By adopting the above technical solution, the rotary source drives the transfer plate to rotate to the discharge end of the hopper to support the shaped pads. The negative pressure source is activated, causing the adsorption pore group to generate negative pressure to adsorb the shaped pads. Subsequently, the drive unit drives the separator plate to penetrate into the storage tank from the outside along the separator port, separating two adjacent shaped pads. Next, the rotary source drives the transfer plate to rotate above the spray liquid conveyor line, the negative pressure is released, and the shaped pads are placed flat on the spray liquid conveyor line. The separator plate ensures that only the bottom shaped pad is removed at a time, avoiding the problem of simultaneous feeding of two or more pads. Through the cooperation of the separator module and the negative pressure adsorption feeding module, the orderly transfer of shaped pads from the hopper to the spray liquid conveyor line is achieved.
[0010] Optionally, the frame is also provided with a counting module, which includes a counting bracket and a counting sensor element; the counting bracket is disposed above the spray liquid transmission line, and multiple counting sensors are disposed at intervals on the counting bracket, with each counting sensor element corresponding to one of the infusion pumps.
[0011] By adopting the above technical solution, after being sprayed, the irregularly shaped pads move along the spray liquid conveyor line to the area below the counting module. Each counting sensor element detects the irregularly shaped pads on its corresponding channel. Each time an irregularly shaped pad is detected passing through, a counting signal is generated and sent to the control module. The counter in the control module accumulates the signals for easy production statistics.
[0012] Optionally, the discharge conveyor line is arranged perpendicular to the spray liquid conveyor line, and the frame is also provided with a discharge transfer mechanism, which is used to transfer the irregular pad on the spray liquid conveyor line to the discharge conveyor line.
[0013] By adopting the above technical solution, the material discharge transfer mechanism and the material discharge transfer line perpendicular to the spray liquid transmission line achieve a 90-degree turning discharge of the material. This helps optimize the production line space, making the equipment layout more compact, and also facilitates the turning and conveying of the finished sprayed irregularly shaped pads to the next process.
[0014] Optionally, the discharge transfer mechanism includes a discharge moving module, a discharge adsorption frame, and a vacuum source. The discharge moving module is used to drive the discharge adsorption frame to move. The discharge adsorption frame includes a discharge frame body and a plurality of suction shells spaced apart at the bottom of the transfer frame body. The suction shells are arranged one-to-one with the storage channel. Each of the suction housings is connected to the vacuum source, and each of the suction housings has a negative pressure hole group at its bottom. The negative pressure hole group includes multiple negative pressure holes, and the distribution shape of the negative pressure holes is adapted to the edge contour of the irregular pad.
[0015] By adopting the above technical solution, when the irregularly shaped pad reaches the end of the spray liquid transmission line, the discharge transfer mechanism starts to operate. The discharge moving module drives the discharge adsorption rack to move above the irregularly shaped pad at the end of the spray liquid transmission line; then, the discharge adsorption rack uses a vacuum source to pick up the irregularly shaped pads on all channels using negative pressure adsorption; then, the discharge moving module drives the discharge adsorption rack with the adsorbed irregularly shaped pads to move laterally above the discharge transmission line; finally, the negative pressure is released, and the irregularly shaped pad is placed on the discharge transmission line. The shape of the negative pressure holes is adapted to the edge contour of the irregularly shaped pad, which can avoid the spraying area to adsorb the irregularly shaped pad, effectively preventing the negative pressure adsorption from damaging or contaminating the sprayed liquid.
[0016] Optionally, a quality detection system is provided between the liquid spraying mechanism and the counting module, and the quality detection system includes a weighing module; The weighing module includes a weighing bracket and multiple checkweighers spaced apart on the weighing bracket. Each checkweigher corresponds to a storage trough and is electrically connected to the control module.
[0017] By adopting the above technical solution, the checkweigher weighs each irregularly shaped pad and transmits the weight data to the control module in real time. The control module compares the measured value with the preset standard weight range to determine the quality status of each irregularly shaped pad. Since the weight of the liquid medicine is constant, the weight of the finished product can directly reflect whether the amount of liquid medicine sprayed meets the standard. The weighing module can promptly detect unqualified products with excessive or insufficient spraying, and can also promptly inspect and adjust abnormal liquid injection in the spraying module.
[0018] Optionally, the quality inspection system further includes a screening material transfer mechanism, which includes a screening material moving module and a screening material adsorption frame. The screening material moving module is used to drive the screening material adsorption frame to move. The material screening and adsorption frame includes a material screening frame body and a plurality of material screening shells spaced apart at the bottom of the material screening frame body. The material screening shells are arranged in a one-to-one correspondence with the material storage channel, and the structure of the material screening shell is the same as that of the material suction shell. Each of the screen housings is connected to a gas supply pipe, and each gas supply pipe is connected to the vacuum source. Each gas supply pipe is equipped with a flow control device, and the flow control device is electrically connected to the control module.
[0019] By adopting the above technical solution, a screening and transfer mechanism was added and linked with the weighing module, enabling automatic sorting of defective irregularly shaped pads. The screening and transfer mechanism adsorbs the irregularly shaped pads sprayed with the pesticide onto the checkweigher and transmits the weighing result to the control module. Based on the weighing result, the control module controls the working state of each flow control component. For irregularly shaped pads that do not meet the quality standards, their corresponding flow control components are closed, and the screening housing does not perform the adsorption action; for qualified irregularly shaped pads, the control module controls the corresponding flow control components to open, creating negative pressure in the screening housing to adsorb the qualified irregularly shaped pads. Then, driven by the screening moving module, the qualified irregularly shaped pads are transferred back to the pesticide spraying transmission line for the next counting process.
[0020] Optionally, the quality inspection system further includes a waste material conveying line, which is located above the spray liquid conveying line, and the screening material transfer mechanism is also used to transfer the irregular pad on the checkweigher to the waste material conveying line.
[0021] By adopting the above technical solution, after the screening and conveying mechanism has transferred the qualified irregularly shaped pads, it will then adsorb the unqualified irregularly shaped pads and transport them to the top of the waste conveyor line. The unqualified irregularly shaped pads will fall onto the waste conveyor line and be collected or processed.
[0022] Optionally, the sprayer includes a sprayer body, an infusion tube connected to the sprayer body, and a spray head connected to one end of the infusion tube, wherein the infusion tube is configured as a universal bamboo joint tube.
[0023] By adopting the above technical solution, during equipment debugging or production changeover, operators can manually bend and shape the universal bamboo tube to adjust the orientation and height of the spray head, thereby ensuring that the liquid can be sprayed at the optimal angle onto the target area of the irregularly shaped pad surface, improving the accuracy and uniformity of spraying.
[0024] On the other hand, this application provides a construction process for a precision digital automatic spraying liquid equipment for irregularly shaped mat production lines, including the following steps: S1, Automatic feeding: Place the irregularly shaped pads into the storage channel of the hopper and start the equipment; S2, Transmission and Positioning: The spray liquid transmission line transports the irregularly shaped pad to the bottom of the liquid spraying mechanism. The material shortage detection unit detects whether each station is short of material in real time. If a material shortage is detected, the control module controls the corresponding infusion pump to stop discharging liquid; if there is no material shortage, the infusion pump sprays the liquid onto the irregularly shaped pad through the sprayer. S3, the counting module's counting sensor element counts the passing irregularly shaped pads and counts the production number; S4, turn to discharge, the discharge conveyor line transports the irregularly shaped pad to the next process.
[0025] In summary, this application includes at least one of the following beneficial effects: 1. When the material shortage detection unit in this application detects a material shortage at the spraying station where the corresponding material pump is located, the control module controls the liquid pump to stop discharging liquid, thereby avoiding the liquid being sprayed directly onto the empty conveyor belt, reducing the waste of liquid and lowering production costs; 2. The hopper in this application is equipped with an inclined storage channel, which, together with the feeding module, facilitates the storage of irregularly shaped pads and the transfer and feeding of each piece, thereby improving feeding efficiency; 3. This application includes a counting module with counting sensors that correspond one-to-one with each infusion pump, which can accurately count the number of irregularly shaped pads sprayed for each infusion pump, facilitating production data management. 4. The weighing module in this application can detect the quality of the irregularly shaped pads, and the screening and conveying mechanism can transfer the unqualified irregularly shaped pads to the waste conveying line according to the detection results, so as to ensure product quality.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail.
[0028] Example 1
[0029] The precision digital automatic spraying equipment for irregularly shaped pad production lines provided in this application includes a frame 1, a conveying mechanism 2, a feeding mechanism, and a spraying mechanism 5. The conveying mechanism 2, the feeding mechanism, and the spraying mechanism 5 are all mounted on the frame 1. The conveying mechanism 2 is used for transporting the irregularly shaped pads, the feeding mechanism transfers the irregularly shaped pads to the conveying mechanism 2, and the spraying mechanism 5 sprays the irregularly shaped pads on the conveying mechanism 2.
[0030] Reference Figure 1 The conveying mechanism 2 includes a spray liquid conveying line 21 and a discharge conveying line 22. The discharge conveying line 22 is located at the end of the spray liquid conveying line 21 and is arranged perpendicular to the spray liquid conveying line 21. In this embodiment, both the spray liquid conveying line 21 and the discharge conveying line 22 are vacuum belt conveyors. (Refer to...) Figure 1 The feeding mechanism includes a hopper 3 and a feeding module 4. The hopper 3 is located at the end of the spray liquid transmission line 21 away from the discharge transmission line 22. Specifically, the hopper 3 is a rectangular trough with one open end. The hopper 3 is inclined downwards towards the spray liquid transmission line 21, and the opening of the hopper 3 is close to the spray liquid transmission line 21. The inclined arrangement facilitates the downward sliding of the irregularly shaped pad under the action of gravity. Multiple partitions are fixed at intervals inside the hopper 3, dividing the hopper 3 into multiple storage channels 31.
[0031] Reference Figure 1 and Figure 2 A material separating module 6 is provided at one end of the material hopper 3 near the spray liquid transmission line 21. The material separating module 6 includes a material separating plate 61 and a drive unit 62. A material separating port 311 is provided on the bottom wall of the storage channel 31. A material separating plate 61 slides in each material separating port 311. One end of each material separating plate 61 is tapered and conical. A connecting strip 63 is provided at the bottom of the material hopper 3. The end of each material separating plate 61 located outside the storage channel 31 is fixedly connected to the connecting strip 63. Multiple drive units 62 are fixedly fixed at intervals on the frame 1. The drive units 62 can be cylinders or electric push rods. One end of the telescopic rod of the drive unit 62 is fixed to the connecting strip 63 and is used to drive the connecting strip 63 to slide, thereby causing the material separating plate 61 to slide into or out of the storage channel 31 to control the discharge of the irregularly shaped pad.
[0032] Reference Figure 1 and Figure 3The feeding module 4 includes a transfer carrier plate 41, a negative pressure source 42, and a rotation source 43. The transfer carrier plate 41 is located above the spraying conveyor line, and its two ends are rotatably connected to the frame 1 via rotating shafts. The rotation source 43 can be a motor used to drive the transfer carrier plate 41 to rotate. The transfer carrier plate 41 is specifically configured as a strip-shaped hollow shell, and multiple sets of adsorption holes are opened on the side wall of the transfer carrier plate 41, with each adsorption hole corresponding to a storage channel 31. The adsorption hole set includes multiple adsorption holes 411 arranged in a rectangular array. The negative pressure source 42 can be a vacuum pump, which is connected to the transfer carrier plate 41 via a hose. When it is necessary to transfer the irregularly shaped pad on the hopper 3 to the spray liquid conveyor line 21, the rotation source 43 drives the side wall of the transfer carrier plate 41 with the adsorption hole set to rotate so that it is opposite to the opening of the hopper 3. The vacuum pump is started to generate negative pressure at each adsorption hole set to adsorb the irregularly shaped pad. Subsequently, the rotating source 43 continues to drive the transfer plate 41 to rotate to a horizontal state, which moves the irregular pad to above the spray liquid transmission line 21. Then, the pressure of each adsorption hole group is released, and the irregular pad falls flat onto the spray liquid transmission line 21 under the action of gravity.
[0033] Refer to Figure 1 and Figure 4 The liquid spraying mechanism 5 includes a control module 51, a spraying module 52, and a material shortage detection unit 53. The spraying module 52 includes a spraying bracket 521 and a delivery pump 522. The spraying bracket 521 is positioned above the liquid transmission line 21 and fixedly connected to the frame 1. Multiple delivery pumps 522 are evenly spaced on the spraying bracket 521 along a direction perpendicular to the liquid transmission line 21, with each delivery pump 522 corresponding to a material storage channel 31. Each delivery pump 522 is connected to a sprayer 523. The sprayer 523 includes a sprayer body 5231, a delivery pipe 5232 connected to the sprayer body 5231, and a spray head 5233 connected to one end of the delivery pipe 5232. In this embodiment, the delivery pipe 5232 is a universal bamboo-joint pipe, facilitating adjustment of the angle and position of the spray head 5233 to achieve precise spraying. The liquid outlet of the spray head 5233 is positioned facing the liquid transmission line 21.
[0034] Reference Figure 1 and Figure 4A material shortage detection unit 53 is located on the side of the spraying bracket 521 near the material hopper 3, and multiple material shortage detection units 53 are provided for corresponding infusion pumps 522. The material shortage detection unit 53 can be a photoelectric sensor or an infrared sensor, used to detect whether the irregularly shaped pad is short of material. Both the material shortage detection unit 53 and the infusion pumps 522 are electrically connected to the control module 51. The control module 51 includes an electrical control cabinet fixed on the frame 1 and an industrial touch screen, which is electrically connected to the electrical control cabinet. The control module 51 controls the working status of each infusion pump 522 according to the detection result of the material shortage detection unit 53. When the material shortage detection unit 53 detects that the spraying station where the corresponding infusion pump 522 is located is short of material, it controls the corresponding infusion pump 522 to stop infusion.
[0035] Reference Figure 1 A counting module 7 is installed on the side of the spraying frame 1 away from the hopper 3. The counting module 7 includes a counting bracket 71 and counting sensors 72. The counting bracket 71 is located above the spray liquid transmission line 21 and is fixedly connected to the frame 1. Multiple counting sensors 72 are fixed at equal intervals on the counting bracket 71 along a direction perpendicular to the spray liquid transmission line 21, and each counting sensor 72 corresponds to a delivery pump 522. The counting sensors 72 can be photoelectric counters or Hall sensors, used to count the passing irregularly shaped pads to determine the production quantity.
[0036] Reference Figure 1 and Figure 5 The frame 1 is also equipped with a discharge transfer mechanism 8. The discharge transfer mechanism 8 includes a discharge moving module 84, a discharge suction frame 81, and a vacuum source 82. The discharge suction frame 81 includes a discharge frame body 811 and multiple suction housings 812 evenly spaced and fixed to the bottom of the transfer frame body. Each suction housing 812 corresponds to a storage channel 31. Each suction housing 812 is connected to the vacuum source 82 via an air pipe, and each air pipe is equipped with an opening and closing element 83; the opening and closing element 83 is used to control the connection and disconnection between the suction housing 812 and the vacuum source 82. In this embodiment, the opening and closing element 83 is an electromagnetic valve, and each electromagnetic valve is electrically connected to the control module 51. (Refer to...) Figure 6 Each suction housing 812 has a negative pressure hole group at its bottom, comprising multiple negative pressure holes 8121. The distribution shape of the negative pressure holes 8121 is adapted to the edge contour of the irregularly shaped pad, allowing it to avoid the spraying area and adsorb the irregularly shaped pad. The discharge moving module 84 is specifically configured as a two-dimensional moving module, including a discharge slider 841. The discharge slider 841 is fixedly connected to one end of the discharge frame 811, enabling the discharge moving module 84 to drive the discharge suction frame 81 to move horizontally and vertically. The discharge moving module 84 can be made of two sets of linear guide rail modules or a motor screw module.
[0037] When the irregularly shaped pad reaches the end of the spray liquid conveyor line 21, the discharge transfer mechanism 8 starts to operate. The discharge moving module 84 drives the discharge adsorption rack 81 to move above the irregularly shaped pad at the end of the spray liquid conveyor line 21; then, the discharge adsorption rack 81 uses the vacuum source 82 to pick up the irregularly shaped pads on all channels by negative pressure adsorption; then, the discharge moving module 84 drives the discharge adsorption rack 81 with the adsorbed irregularly shaped pad to move laterally to the top of the discharge conveyor line 22; after the discharge moving module 84 drives the discharge adsorption rack 81 to a suitable height, the negative pressure is released, and the irregularly shaped pad is placed on the discharge conveyor line 22, and moves to the next process under the action of the discharge conveyor line 22.
[0038] The implementation principle of this embodiment is as follows: the feeding mechanism transfers the irregularly shaped pads from the hopper 3 to the spray liquid transmission line 21, and the conveying mechanism 2 transports the irregularly shaped pads to the area below the spray liquid mechanism 5. The material shortage detection unit 53 detects whether each station is short of material in real time. If a material shortage is detected, the control module 51 controls the corresponding infusion pump 522 to stop dispensing liquid, avoiding waste of liquid and equipment contamination; if there is no material shortage, the infusion pump 522 sprays the liquid onto the irregularly shaped pads through the sprayer 523. This design effectively improves production efficiency, reduces production costs, solves problems existing in the prior art, and makes a significant improvement to the prior art.
[0039] Example 2
[0040] Reference Figure 7 The difference between this embodiment and the above embodiments is that a quality detection system 9 is provided between the liquid spraying mechanism 5 and the counting module 7. The quality detection system 9 includes a weighing module 91, a screening and conveying mechanism, and a waste conveying line 94. The weighing module 91 includes a weighing bracket 911 and a checkweigher 912. The weighing bracket 911 is fixed on the frame 1. Multiple checkweighers 912 are equally spaced along a direction perpendicular to the liquid spraying conveying line 21, and each checkweigher 912 corresponds to a storage tank 31. Each checkweigher 912 is electrically connected to the control module 51.
[0041] Reference Figure 7 and Figure 8The screening and transfer mechanism includes a screening moving module 92 and a screening suction frame 93. The screening moving module 92 drives the screening suction frame 93 to move, and the screening moving module 92 has the same structure as the discharge moving module, also being a two-dimensional moving module. The screening moving module 92 includes a screening slider 921. The screening suction frame 93 includes a screening frame body 931 and multiple screening housings 932 fixed at intervals to the bottom of the screening frame body 931. The screening frame body 931 is fixedly connected to the screening slider 921, allowing the screening moving module 92 to drive the screening suction frame 93 to move horizontally and vertically. The screening housings 932 are arranged one-to-one with the storage channels 31, and the structure of the screening housings 932 is the same as that of the suction housing 812. Each screen housing 932 is connected to a gas supply pipe 933, and each gas supply pipe 933 is connected to a vacuum source 82. Each gas supply pipe 933 is equipped with a flow control device 934. The flow control device 934 is specifically selected as an electromagnetic flow control valve, and each electromagnetic flow control valve is electrically connected to the control module 51.
[0042] The screening material moving module 92 is activated, driving the screening material adsorption frame 93 to move and adsorb the irregularly shaped pads sprayed with liquid medicine onto the checkweigher 912. The screening material transfer mechanism adsorbs the irregularly shaped pads sprayed with liquid medicine onto the checkweigher 912, which weighs each irregularly shaped pad and transmits the weight data to the control module 51 in real time. Based on the weighing results, the control module 51 compares the measured value with the preset standard weight range to determine the quality status of each irregularly shaped pad, and then controls the working status of each flow control component 934 according to the corresponding quality status. For irregularly shaped pads that do not meet the quality standards, their corresponding flow control component 934 is turned off, and the screening material housing 932 does not perform the adsorption action; for qualified irregularly shaped pads, the control module 51 controls the corresponding flow control component 934 to turn on, so that the screening material housing 932 generates negative pressure, adsorbing the qualified irregularly shaped pads, and then, driven by the screening material moving module, the qualified irregularly shaped pads are transferred back to the liquid medicine transmission line 21 for the next counting process.
[0043] The waste conveyor line 94 is located above the spray liquid conveyor line 21 and is fixed to the frame 1. After the screening and transfer mechanism transfers the qualified irregularly shaped pads to the spray liquid conveyor line 21, the screening and moving module 92 continues to drive the screening and adsorption rack 93 to move above the checkweigher 912. The control module 51 controls the working status of each flow control component 934 again based on the previous weighing results. For checkweighers 912 with qualified quality, the corresponding flow control component 934 is closed, and the screening housing 932 does not perform adsorption. For checkweighers 912 with unqualified quality, the control module 51 controls the corresponding flow control component 934 to open, so that the screening housing 932 generates negative pressure, adsorbing the unqualified irregularly shaped pads on the checkweigher 912. Then, driven by the screening and moving module 92, the qualified irregularly shaped pads are transferred to the waste conveyor line 94 for subsequent centralized processing of the unqualified irregularly shaped pads.
[0044] During the subsequent process of the material transfer mechanism 8 transferring the qualified irregular pad to the material transfer line 22, the control module 51 also controls the opening and closing part 83 corresponding to the qualified irregular pad to open according to the weighing result, so that only the suction shell 812 corresponding to the qualified irregular pad performs the adsorption action.
[0045] Example 3
[0046] The precision digital automatic spraying process for irregularly shaped mat production lines provided in this application includes the following steps: The precision digital automatic spraying equipment for irregularly shaped mat production lines described in Example 1 is used to spray pesticide onto the irregularly shaped mats. S1, Automatic feeding: Place the irregularly shaped pads into the storage channel 31 of the hopper 3 and start the equipment. Operators need to neatly arrange the irregularly shaped pads into the storage channel 31. Due to the inclined design of the storage channel 31, the irregularly shaped pads will naturally slide down to the separating plate 61 under gravity. After starting the equipment, the separating module 6 and the feeding module 4 begin to work. The separating plate 61 slides under the drive of the drive unit 62, controlling the individual discharge of the irregularly shaped pads. The transfer plate 41 of the feeding module 4 rotates under the drive of the rotating source 43. The negative pressure source 42 generates negative pressure through the adsorption hole group to adsorb the irregularly shaped pads and transfer them to the spray liquid transmission line 21.
[0047] S2, Transmission and Positioning: The spray liquid transmission line 21 transports the irregularly shaped pad to the area below the spray liquid mechanism 5. The material shortage detection unit 53 detects in real time whether each station is short of material. If a material shortage is detected, the control module 51 controls the corresponding infusion pump 522 to stop dispensing liquid; if there is no material shortage, the infusion pump 522 sprays the liquid onto the irregularly shaped pad through the sprayer 523. The spray liquid transmission line 21 is driven by a motor, stably transporting the irregularly shaped pad to the designated position.
[0048] The material shortage detection unit 53 can use a photoelectric sensor or an infrared sensor to monitor the presence of the irregularly shaped pad in real time and transmit the signal to the control module 51.
[0049] S3, the counting sensor element 72 of the counting module 7 counts the passing irregularly shaped pads and calculates the production quantity. When an irregularly shaped pad passes by, the counting sensor element 72 records the number of irregularly shaped pads, which is convenient for calculating production progress and output.
[0050] S4, turning to discharge, the discharge conveyor line 22 transports the irregularly shaped pad to the next process. The discharge moving module of the discharge transfer mechanism 8 drives the discharge adsorption rack 81 to move. The discharge adsorption rack 81 adsorbs the irregularly shaped pad through the negative pressure hole group at the bottom of the suction housing 812, and transfers it from the spray liquid conveyor line 21 to the vertically set discharge conveyor line 22. The discharge conveyor line 22 transports the irregularly shaped pad to the next process for subsequent processing.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
