Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a spraying device for rust prevention treatment of nail rack surfaces, comprising... The nail conveying mechanism 100 includes a housing 110, inside which a nail transmission assembly 120 is installed. The nail transmission assembly 120 includes two sets of chains 124, which are arranged in parallel and staggered. An electromagnet 126 is installed on the outer side of the chain 124 for limiting, and the electromagnet 126 is magnetically connected to the nails. The nail spraying mechanism 200 is respectively set with the two sets of chains 124. With the cooperation of the chain 124, electromagnet 126 and motor 121 in the nail conveying mechanism 100, the automatic feeding, conveying, flipping and unloading of nails can be realized without frequent manual intervention, which greatly improves production efficiency and is suitable for large-scale nail anti-rust treatment needs.

[0024] Please see Figure 3 and Figure 4 Two sets of chains 124 are driven by a sprocket set to achieve synchronous differential motion, ensuring smooth rotation of the nail pack; the electromagnet 126 has a built-in Hall sensor to provide real-time feedback on the magnetic attraction status, and works with the PLC controller to precisely control the power supply; the nail pack spraying mechanism 200 is equipped with a servo motor driven spray gun module, which can automatically adjust the spraying distance and angle according to the nail pack specifications to meet the anti-rust spraying needs of nail packs of different lengths and diameters.

[0025] The housing 110 includes a base plate 111. A first transmission housing 112 and a second transmission housing 114 are fixedly connected to the two opposite corners of the upper part of the base plate 111, respectively. A first spraying housing 113 and a second spraying housing 115 are fixedly installed at the other two opposite corners of the upper part of the base plate 111, respectively. The bottom of the base plate 111 integrates a shock-absorbing pad and a leveling foot. The shock-absorbing pad is made of nitrile rubber to reduce the transmission of vibration during equipment operation. The leveling foot supports ±5mm height fine adjustment to ensure the installation accuracy of the equipment.

[0026] The first spray shell 113 and the first transmission shell 112 are arranged in parallel, and the second transmission shell 114 and the second spray shell 115 are arranged in parallel. They also have built-in parallel baffles to prevent splashing during spraying.

[0027] The pin drive assembly 120 also includes a motor 121, which is fixedly mounted on one end of the top of the first drive housing 112 and the second drive housing 114. A drive sprocket 122 is mounted on the output end of the motor 121, and a guide sprocket 123 is sleeved on the other end of the drive sprocket 122. The top of the guide sprocket 123 is rotatably mounted on the other end of the first drive housing 112 and the second drive housing 114. The motor 121 is a servo motor with a planetary reducer and a reduction ratio of 1:20, achieving precise low-speed control of 0.1 r / min. Both the drive sprocket 122 and the guide sprocket 123 undergo carburizing and quenching treatment, achieving a hardness of HRC58-62, extending the service life of the chain meshing. The first drive housing 112 and the second drive housing 114 are L-shaped, rotating 90 degrees counterclockwise to prevent dust from entering.

[0028] The pin drive assembly 120 also includes a clamping plate 125, which is U-shaped and is clamped onto each link of the chain 124. An electromagnet 126 is installed on the outside of the clamping plate 125.

The limit bolt 127 adopts an anti-loosening nut structure and is used with pre-applied thread adhesive. The anti-loosening effect reaches level 9 under vibration. The top of the bolt is inlaid with a polyurethane buffer pad to avoid rigid contact damage to the chain surface.

[0030] Please see Figure 5 The nail-coating mechanism 200 includes a front-end coating component 210 and a rear-end coating component 220. The front-end coating component 210 is located at the outer end of the first coating shell 113, and is correspondingly positioned to the top and one side of the nails. The rear-end coating component 220 is located at the end of the second coating shell 115 near the first transmission shell 112. The front-end coating component 210 is equipped with a laser displacement sensor to detect the height of the nails in real time and automatically adjust the Z-axis height of the spray gun to adapt to the size fluctuations of different batches of nails. The rear-end coating component 220 is equipped with a flow closed-loop control system, with a paint flow control accuracy of ±1%, ensuring uniform coating thickness on both sides. The nail spraying mechanism 200 also includes a drying component 230, which is located at one end of the first spraying shell 113 near the second transmission shell 114 and at the other end of the second spraying shell 115 away from the first transmission shell 112. A storage drawer 260 is provided between the second spraying shell 115 and the second transmission shell 114. The drying component 230 uses infrared radiation heating, with a temperature uniformity of ±3℃ in the heating zone and a heating rate of 5℃ / s. It is used in conjunction with closed-loop control by temperature and humidity sensors to ensure the quality of coating drying. The storage drawer 260 is equipped with a photoelectric counting sensor, which triggers an audible and visual alarm when the drawer is full, reminding the user to change the drawer manually.

[0031] A collection tray 240 is provided directly below the front spraying assembly 210 and the rear spraying assembly 220. The collection tray 240 is inclined and passes through the first transmission housing 112 and the second transmission housing 114 respectively. A circulation pipe 250 is connected to one side of the collection tray 240. The inner wall of the collection tray 240 is coated with a Teflon coating with a thickness of 50μm and a surface roughness Ra≤0.8μm to reduce paint residue and adhesion. The circulation pipe 250 has a built-in gear pump with a flow rate of 5L / min. With the help of a filter (filtration accuracy of 50μm), the paint is recycled in a closed loop with a recovery rate of over 95%.

[0032] The equipment is equipped with a PLC controller (core control unit, with added necessary components), which acts as the "brain" for controlling the on / off state of the electromagnet. Through preset programs and sensor feedback, it precisely controls the timing of the electromagnet's current flow. The overall logic chain is as follows: Sensor detects signal → PLC logic operation → Relay / solid-state relay actuation → Electromagnet coil is energized or de-energized II. Triggering conditions and execution process of electromagnet switching at each stage 1. Feeding and adsorption stage (first set of chain electromagnets are energized) Triggering conditions: An external feeding robot transports the nails to the feeding end of the first transmission housing 112. A photoelectric sensor (newly added and installed at the feeding port) detects the nails in place and transmits an electrical signal (24V level signal) to the PLC.

[0033] PLC execution: The PLC calls a preset program and sends a "power-on command" to the corresponding relay module to control the relay coil of the electromagnet 126 on the outer side of the first chain 124 to be energized and the contacts to close.

[0034] Hardware execution: After the relay contacts close, the DC power supply (newly added, outputting a stable 24V DC) supplies power to the electromagnet coil, and the electromagnet generates magnetic force to attract the nails; at the same time, the Hall sensor built into the electromagnet feeds back an "attraction status signal" (such as a magnetic field strength up to standard signal) to the PLC to confirm successful attraction.

[0035] 2. Flip-over switching phase (first group powered off, second group powered on) Triggering conditions: As the pins move with the chain to the intersection of the two chains, the displacement sensor (newly added, installed on the chain track) detects that the pins have reached the flip position and sends a position signal (analog signal 0-10V) to the PLC.

[0036] PLC execution: The PLC starts the "flip timing program", first sending a "power off command" to the relay corresponding to the first group of electromagnets to disconnect their power supply; after a delay of 0.2s (to avoid magnetic interference), it sends a "power on command" to the relay of the second group of electromagnets.

[0037] Hardware execution: The first set of electromagnet relay contacts opens, de-energizing the coil and eliminating the magnetic force; the second set of electromagnet relay contacts closes, energizing the coil and generating a magnetic force that attracts the already flipped pins, completing the switching. During this process, a time relay (newly added to ensure precise timing) strictly controls a 0.2s delay to ensure the pins flip smoothly.

[0038] 3. Material release stage (second set of electromagnets de-energized) Triggering conditions: When the nails move above the storage drawer 260, the infrared sensor (newly added, installed at the feeding port) detects that the nails have reached the feeding position and sends a position signal to the PLC.

[0039] PLC execution: The PLC sends a "feeding command" to de-energize the second set of electromagnet relays.

[0040] Hardware execution: The second set of electromagnet relay contacts disconnect, the coil loses power, the magnetic force disappears, and the nails fall into the storage drawer due to gravity; at the same time, the counter records the quantity of material dispensed, and triggers an alarm when the limit is reached.

[0041] The aforementioned components and circuits are all conventional components and circuits in the existing technology and in this field. At the same time, some necessary components such as built-in pumps are also included to ensure the normal operation of the entire equipment. Front-end spraying: The pins enter the first spraying shell 113 along with the chain 124. The front-end spraying component 210 is started. The spray gun (newly added) is driven by the servo motor and sprays the top of the pins and the non-adsorbed side according to the preset program. The paint is transported from the external storage tank (newly added) to the spray gun through the circulation pipe 250 via the gear pump (newly added, flow rate 5L / min). The spraying pressure is stably controlled at 0.3-0.5MPa by the pressure regulating valve (newly added).

[0042] Front-end drying: After spraying, the nails are moved to the drying component 230 area. The infrared heating tube (newly added) is turned on to raise the temperature to 60-80℃. In conjunction with the hot air circulation system (newly added), the coating drying is accelerated. Temperature and humidity sensors provide real-time feedback data to ensure a stable drying environment.

[0043] Nail roll flipping: When the nail roll reaches the intersection of the two sets of chains 124, the electromagnet 126 of the first set of chains 124 is de-energized, and at the same time the electromagnet 126 of the second set of chains 124 is energized. The nail roll is attracted to the second set of chains 124, achieving a 180° flip, exposing the unpainted side.

[0044] Rear-end spraying and drying: The pins enter the second spraying shell 115, and the rear-end spraying component 220 repeats the front-end spraying process; then, it is dried a second time through the second drying component 230 to ensure that the coating is completely cured.

[0045] Material unloading and storage: After processing, the nails move with the chain 124 to the storage drawer 260. The electromagnet 126 is de-energized, and the nails fall into the storage drawer 260. The photoelectric counter (newly added) counts the quantity in real time and triggers an alarm when the drawer is full.

[0046] Paint recycling: Paint dripping during the spraying process is collected by the collection tray 240 and flows into the filter (newly added, 50μm precision) through the inclined channel. The filtered paint is returned to the storage tank through the circulation pipe 250. The gear pump continuously circulates the paint to ensure its fluidity.

[0047] Working principle: Nail feeding and conveying: The nails are aligned and attracted to the electromagnet 126 on the outside of the chain 124 by a robot or manual operation. The motor 121 is started, which drives the transmission sprocket 122 to rotate, thereby causing the chain 124 to move along the trajectory of the guide sprocket 123 in the first transmission housing 112 and the second transmission housing 114 to realize the conveying of the nails.

[0048] Front-end spraying and drying: The pins move along the chain 124 and pass through the front-end spraying component 210, which sprays the top and one side of the pins. After spraying, the pins continue to move to the drying component 230, which dries the pins to preliminarily set the coating.

[0049] Nail position switching: After drying, the nails are moved to a position where they contact another set of chains 124 that are set in parallel and intersecting. The electromagnet 126 on the front chain 124 is de-energized, and the electromagnet 126 on the rear chain 124 is energized. The nails are attracted to the rear chain 124, realizing the position change and preparing for the spraying on the other side.

[0050] Rear end spraying, drying and unloading: The nail pack moves along the rear end chain 124, passes through the rear end spraying component 220 to spray the other side, and then passes through the drying component 230 for secondary drying; the dried nail pack moves to the top of the storage drawer 260, the electromagnet 126 is de-energized, and the nail pack falls into the storage drawer 260 for collection.

[0051] Paint recycling: When the front spraying component 210 and the rear spraying component 220 are spraying, excess liquid drips into the inclined collection tray 240 and is transferred through the circulation pipe 250 to realize the recycling of paint.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
