Description

Technical Field

[0001] This invention relates to the field of filling and conveying mechanisms, and in particular to an automatic intelligent filling and conveying mechanism for processing environmentally friendly water-based paints. Background Technology

[0002] The filling and conveying mechanism is an automated equipment that integrates conveying, filling, and testing. It is mainly used in the production process of water-based paints to automatically transport paint buckets to the filling station and complete accurate filling.

[0003] In existing technology: When operators add water-based paint to the buckets, they first need to adjust the overall height of the filling platform according to the bucket height. Then, the empty buckets are placed one by one onto the chain conveyor belt, which transports the buckets. Once a sensor detects that a bucket has reached its position, it triggers a positioning mechanism to clamp the bucket and pauses the chain conveyor belt. Subsequently, the filling head descends to begin filling. During the filling process, some equipment is equipped with a pressure sensor that monitors the filling volume in real time. Filling stops when a preset value is reached. After filling is complete, the stop mechanism resets, the chain conveyor belt restarts, and the finished bucket is delivered.

[0004] Regarding the above-mentioned issues, the following technical defects exist: When the paint buckets move to the filling station along the chain conveyor belt, the paint buckets need to be positioned to prevent them from shifting during transportation. However, the existing positioning mechanisms are limited in effectiveness. The paint buckets themselves have a high center of gravity, and the chain conveyor belt is prone to shaking, shifting, or tipping over during start-up, stopping, and acceleration. This can cause the filling nozzle of the paint bucket to misalign with the filling gun, resulting in misalignment. During filling, the filling gun may dispense paint outside the bucket. In particular, if the paint bucket tipps over, it can cause the entire production line to stop, seriously affecting filling efficiency and production continuity.

[0005] Therefore, it is necessary to provide a new type of automatic intelligent filling and conveying mechanism for environmentally friendly water-based paint processing to solve the above-mentioned technical problems. Summary of the Invention

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, when the paint bucket moves to the filling station with the chain conveyor belt, it is necessary to adjust the conveying position of the paint bucket on the chain conveyor belt to prevent the paint bucket surface from abutting against the side wall of the mounting frame of the conveyor belt during the conveying process, which would cause the bucket body to shift or even tilt. Existing positioning mechanisms can be used to accomplish this. However, the positioning effect of existing positioning mechanisms is limited. In addition, the paint bucket itself has a high center of gravity. During the start-up, stop and acceleration of the chain conveyor belt, the bucket mouth will be tilted and misaligned. The bucket mouth and the filling gun cannot be aligned, causing water-based paint to overflow during subsequent filling, which seriously affects filling efficiency and production continuity. The limiting mechanism can contact the bottom of the paint bucket with the upper part of the lifting plate. When the lifting plate descends, it drives the limiting plates on both sides to move towards the middle in a coordinated manner through the gear and rack linkage, thereby achieving automatic centering and clamping of the paint bucket. The rubber contact strip makes elastic contact with the bucket body, which can prevent damage to the bucket body and provide stable clamping force. After the paint bucket is clamped, the limiting mechanism automatically locks the lifting plate by inserting the positioning rod into the positioning hole, so that the limiting plate maintains a continuous clamping state on the paint bucket without the need for external power. When the paint bucket is conveyed to the end of the chain conveyor belt, the contact plate and the roller automatically unlock and reset, realizing the automatic release of the limiting mechanism at the end of the chain conveyor belt without manual intervention, thus reducing the labor intensity of operators. The limiting mechanism also enables rapid adjustment of the paint bucket opening angle through a quick-adjustment component. When it is found that the bucket opening is not aligned with the filling gun during the filling process, the operator only needs to pull the handle to release the locking of the lifting plate and easily rotate between the two limiting plates to adjust the bucket opening angle. After adjustment, pressing down the paint bucket again will lock it again without having to remove the paint bucket from the limiting mechanism. This effectively solves the problem of inaccurate filling alignment caused by bucket opening angle deviation, further improving filling accuracy and ease of operation.

[0018] 2. In this invention, during the filling process, the existing funnel lacks a positioning detection function. When the funnel is tilted from the mouth of the bucket, it cannot be detected in time and the filling cannot be stopped. This can easily cause water-based paint to overflow from the mouth of the paint bucket, which not only wastes materials but also pollutes the equipment and working environment. The material guiding mechanism can work with a micro switch via a detection rod. When the funnel and the barrel opening are misaligned, the spherical block at the lower end of the detection rod contacts the edge of the barrel opening and cannot enter the barrel. The button of the micro switch is triggered by the squeezing contact with the trigger block, which disconnects the circuit of the filling equipment and immediately stops the extension and retraction of the filling gun and the filling operation. This effectively prevents water-based paint from overflowing and being wasted due to barrel opening misalignment, and avoids paint contamination of the equipment and working environment. When the funnel and the barrel opening are properly aligned, the lower end of the funnel, along with the detection rod, can smoothly enter the inside of the paint barrel opening. When the lifting arm descends to the set position, the trigger rod triggers the proximity switch to close, which connects the control circuit of the filling gun drive element. After the drive element is energized, it drives the valve core rod to move upward to open the feeding channel and start filling. This realizes automatic linkage control between the funnel's positioning and the start of filling, without the need for manual intervention, thus improving the automation and reliability of the filling operation. During the descent of the funnel, after the force plate contacts the upper surface of the paint bucket, the meshing transmission of the adjusting rack and adjusting gear drives the closed ball valve to automatically rotate 90 degrees to open the discharge port at the lower end of the funnel, making the inner cavity of the funnel connected to the inner cavity of the paint bucket. After filling is completed, the funnel rises, and the fifth spring releases potential energy to drive the closed ball valve to rotate 90 degrees in the opposite direction to reset, sealing the lower end of the funnel. This effectively solves the problem of residual water-based paint from the filling gun dripping from the bottom of the funnel, avoiding paint dripping and contaminating the chain conveyor belt, mounting frame, and paint bucket body, thus improving the clean production level of the filling process.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, such as Figures 1-24 As shown, the present invention provides an automatic intelligent filling and conveying mechanism for processing environmentally friendly water-based paint, including a mounting frame 1, a chain plate conveyor belt 4, and a paint bucket 5. The chain plate conveyor belt 4 is composed of several chain plates that are hinged together in sequence. Adjacent chain plates are hinged together. Two sprockets are installed on both sides of the inner wall of the mounting frame 1. The same traction chain is provided on each pair of sprockets. Several chain plates are fixedly installed on the two chains. Among the several chain plates, every three adjacent chain plates form a group. The same limiting mechanism 2 is provided on the surface of the three chain plates in each group. The upper surface of the mounting frame is provided with a material guiding mechanism 3. The automatic intelligent filling conveyor belt for environmentally friendly water-based paint processing is an automated conveying equipment used to transport paint buckets 5 to the filling station. It is usually composed of a mounting frame 1, two parallel traction chains set on the side wall of the mounting frame 1, several chain plates installed on the chains, and sprockets that drive the chain movement. The chain plate conveyor belt 4 is used to carry and transport the paint buckets 5, enabling them to move along the direction of the production line. The chain plates, as a carrying platform, can provide stable support for the paint buckets 5. Paint bucket 5 is a closed-top paint bucket. The body of the closed-top paint bucket 5 is formed by rolling and welding steel plates. All welding related to sealing, such as the longitudinal seams of the bucket body and the connection between the bottom and the body, is completed at this stage. The lid and the body are an integral sealed structure and cannot be disassembled. When using the water-based paint inside the bucket, it can be pumped out through the small hole at the top. During the production and filling operation, paint can be added through the small hole at the top of the paint bucket 5. After filling, the lid can be used to seal the bucket. The closed-top paint bucket 5 has stronger sealing performance than the ordinary open-top paint bucket 5, making it suitable for long-distance transportation and storage. When the paint bucket 5 moves to the filling station along the chain conveyor belt 4, the conveying position of the paint bucket 5 on the chain conveyor belt 4 needs to be adjusted to prevent the surface of the paint bucket 5 from abutting against the side wall of the mounting frame 1 of the chain conveyor belt 4 during the conveying process, which would cause the bucket to shift or even tilt. The existing positioning mechanism can be used to accomplish this, but the existing positioning mechanism has limited effectiveness and often causes the filling nozzle and the filling gun to not be aligned, resulting in filling overflow. Once the bucket tilts, it will cause the production line to stop, which will seriously affect the filling efficiency and production continuity. At this time, the above problems can be solved by the limiting mechanism 2. The limiting mechanism 2 can automatically limit the paint bucket 5 to prevent the paint bucket 5 from shifting or even tilting during the transportation process. In addition, the limiting mechanism 2 also makes it convenient for workers to adjust the feeding angle between the filling port of the paint bucket 5 and the filling gun. During the processing and filling of environmentally friendly water-based paint, the laser beam sensor group 38 consists of a laser emitter and a laser receiver, which are respectively set on both sides of the support frame plate 31. When the paint bucket 5 is transported to the filling station, and the outer peripheral wall of the paint bucket 5 blocks the laser emitted by the laser emitter, the laser receiver cannot receive the signal. At this time, it means that the paint bucket 5 is in place. The laser receiver will transmit the paint bucket 5 arrival signal to the control device 37. The control device 37 will control the chain plate conveyor belt 4 to stop working. At this time, the paint bucket 5 will be directly below the filling equipment. When the filling equipment is started, it will drive the filling gun to rise and fall. The filling gun injects water-based paint into the bucket through the funnel 33. However, the existing filling equipment lacks a positioning detection function for the funnel 33, which cannot determine whether the funnel 33 is aligned with the mouth of the paint bucket 5. This will cause the filling process to be unable to be cut off in time when the funnel 33 is misaligned with the mouth of the bucket, resulting in a large amount of water-based paint not flowing into the bucket along the mouth of the paint bucket 5, causing waste. After the filling is completed, the bottom of the funnel 33 will remain open and will not close automatically. The water-based paint residue at the nozzle of the filling gun will easily drip from the bottom of the funnel 33, which will not only waste materials, but also contaminate the chain conveyor belt 4, the mounting frame 1 and the paint bucket 5, increasing the difficulty of subsequent cleaning. At this time, the above problem can be solved by the material guiding mechanism 3. The material guiding mechanism 3 cooperates with the micro switch 341 through the detection rod 343. When the funnel 33 is misaligned with the barrel opening, it can automatically cut off the filling program of the filling gun to solve the problem that water-based paint overflows when the funnel 33 is not aligned with the barrel opening and cannot be detected and stopped in time. After the filling is completed, the bottom of the funnel 33 can be automatically closed by the material guiding mechanism 3 to solve the problem that the water-based paint remaining in the nozzle of the filling gun will drip from the bottom of the funnel 33, causing material waste and contamination of the chain conveyor belt 4.

[0024] The following section will explain the specific settings and functions of the limiting mechanism 2 and the guiding mechanism 3.

[0025] like Figures 2-16As shown, the limiting mechanism 2 includes multiple working grooves 21 equidistantly opened on the outside of the chain plate conveyor belt 4. The same working groove 21 is opened on the surface of every three adjacent chain plates. The working groove 21 is composed of a first groove segment, a second groove segment and a third groove segment. The three groove segments are opened on three chain plates respectively. The bottom wall of the working groove 21 is provided with a telescopic groove 211. The same guide strip 222 is fixedly connected to both sides of the inner wall of the telescopic groove 211. The two ends of the guide strip 222 are slidably connected with sliding racks 221. The sliding racks 221 are slidably sleeved on the outside of the guide strips 222. The upper surface of the sliding racks 221 is fixedly connected with a limiting plate 22. The side wall of the limiting plate 22 is fixedly connected with several fixing rods 224. Every two fixing rods 224 form a group. The same mounting rod is rotatably connected between each group of fixing rods 224. A contact strip 223 is fixedly connected to the arc surface of the mounting rod. The contact strip 223 is a rubber strip. Both ends of the arc surface of the mounting rod are fitted with coil springs. The two ends of the coil springs are fixedly connected to the contact strip 223 and the top wall of the fixing rod 224, respectively. The inner wall of the telescopic groove 211 slides through a lifting plate 23. Lifting racks 231 are fixedly connected to both sides of the lifting plate 23. Connecting gears 232 mesh with the tooth surfaces of the lifting racks 231. A transmission gear 233 is fixedly connected to one side of the connecting gear 232. The two transmission gears 233 mesh with the tooth surfaces of the two sliding racks 221 respectively. The transmission gears 233 and the connecting gears 232 are jointly sleeved on a power rod. The transmission gears 233 and the connecting gears 232 are fixedly connected to one of the chain plates through a connecting rod. Both ends of the power rod are fixedly connected to one of the chain plates. An adjustment component is provided at the end of the lifting plate 23 away from the telescopic groove 211. When paint bucket 5 is in the initial bucket delivery area: Initial state of limiting mechanism 2: The two limiting plates 22 together with the sliding rack 221 are set at a position far apart from each other in the working groove 21. The pointed end of the positioning rod 252 is in the positioning hole 251 below. The positioning rod 252 can lock the sliding state of the positioning plate 25 and the lifting plate 23 in the telescopic groove 211. One end of the lifting plate 23 and the positioning plate 25 will protrude from inside the telescopic groove 211 and between the two limiting plates 22. When the three trough segments are in the straight conveying position of the three chain plates, they can be combined to form a complete working trough 21. At this time, the bottom of the paint bucket 5 contacts the lifting plate 23 extending from the inner wall of the telescopic trough 211, and the paint bucket 5 is pressed down. The lifting plate 23 will move downward under the force, and drive the lifting racks 231 installed on both sides to move together. The movement of the lifting racks 231 will drive the connecting gear 232 and the transmission gear 233 to rotate. The movement of the connecting gear 232 and the transmission gear 233 will rotate on the connecting rod. In addition, the transmission gear 233 meshes with the sliding rack 221, so that the lifting plate 23 can drive the lifting rack 231 to move downward. Through the connecting gear 232 and the transmission gear 233 as the medium, the downward movement is converted into the horizontal movement of the sliding rack 221 on the guide bar 222, so that the two sliding racks 221 drive the two limiting plates 22 to move closer to each other, so that the sliding racks 221 can drive the limiting plates 22 to contact the outer peripheral wall of the paint bucket 5. When the limiting plate 22 contacts the outer peripheral wall of the paint bucket 5, the contact strip 223 on the fixing rod 224 will contact the paint bucket 5 first. The cross section of the contact strip 223 is arc-shaped. When the contact strip 223 is under force, it will rotate on the mounting rod. The rotation of the contact strip 223 will make its arc surface contact the paint bucket 5 better. In addition, the contact strip 223 is a rubber strip, so it can restrict the paint bucket 5. When the contact strip 223 rotates, it will squeeze the coil spring on the mounting rod and the fixing rod 224. The coil spring will twist and store elastic potential energy, so that the contact strip 223 can be reset when the paint bucket 5 is removed from the chain plate. The adjustment assembly includes an adjustment plate 24, which is fixedly connected to one end of a lifting plate 23. Sliding holes 241 are provided at both ends of the side of the adjustment plate 24. An inner rod 243 slides through the inner wall of the sliding hole 241 and passes through it. A first spring is sleeved on the outside of the inner rod 243. The inner rod 243 is located inside a sliding cylinder 242, and its two ends are fixedly connected to the top and bottom of the inner cavity of the sliding cylinder 242. The two ends of the first spring are fixedly connected to the top wall of the adjustment plate 24 and the top wall of the sliding cylinder 242, respectively. The first spring applies tension to the adjustment plate 24. The sliding cylinder 242 is hollow, and a strip groove is provided on its side. The sliding cylinder 242 is slidably disposed within the adjustment plate 24. A retaining ring 244 is fixedly connected to the middle section of the sliding cylinder 242. One end of the sliding cylinder 242 is fixedly connected to the side of an adjacent chain plate. A positioning assembly is provided on the side of the lifting plate 23 away from the transmission gear 233. During the process of the paint bucket 5 contacting the lifting plate 23 and pushing the lifting plate 23 to move downward in the telescopic groove 211, the lifting plate 23 will drive the adjusting plate 24 fixed thereto to move together. The adjusting plate 24 can slide downward on the surface of the inner rod 243 through the sliding hole 241. The adjusting plate 24 itself will also move downward along the surface of the sliding cylinder 242. During the sliding process, the adjusting plate 24 can gradually pull the first spring, so that the first spring stores elastic potential energy. When the paint bucket 5 is removed from the chain conveyor belt 4, the first spring releases its elastic potential energy, which pulls the adjusting plate 24 upward. The adjusting plate 24 then moves the lifting plate 23 upward, pushing the lifting plate 23 out of the telescopic groove 211 for subsequent use. The retaining ring 244 installed on the slide cylinder 242 limits the sliding of the adjusting plate 24 when the first spring releases its elastic potential energy. The retaining ring 244 improves the accuracy and stability of the adjusting plate 24 in resetting the lifting plate 23. The positioning assembly includes two positioning plates 25, which are slidably connected to the chain plate. The two positioning plates 25 are symmetrically fixedly connected to the two sides of the lifting plate 23. Two positioning holes 251 are opened on the top section of the side of the positioning plate 25. A guide block is fixedly connected to the top wall of the lower positioning hole 251. The guide block facilitates the positioning rod 252 to slide out of the positioning hole 251. The end of the positioning rod 252 inserted into the positioning hole 251 is conical. A fixing cylinder 253 is slidably inserted through the outer side of the middle section of the positioning rod 252. The fixing cylinder 253 is fixedly connected to the side of one of the chain plates. A sliding piece 2531 is slidably provided at the end of the inner cavity of the fixing cylinder 253 near the positioning plate 25. The sliding piece 2531 is fixedly sleeved on the outer peripheral wall of the adjacent positioning rod 252. A second spring is sleeved on the arc surface of the positioning rod 252. The two ends of the second spring abut against the sliding piece 2531 and the end of the inner cavity of the fixing cylinder 253 away from the positioning plate 25, respectively. A release assembly is provided on the side of the positioning rod 252 away from the positioning plate 25. The release assembly includes a connecting plate 254, which is L-shaped. The long arm end of the connecting plate 254 is fixedly connected to one end of the positioning rod 252, and the short arm end of the connecting plate 254 is fixedly connected to a contact plate 2541. One side of the contact plate 2541 is sloped. Both sides of the inner wall of the mounting frame 1 are fixedly connected to connecting rods 2542. One end of the connecting rod 2542 is fixedly connected to a roller 2543. The adjusting plate 24 is provided with a quick-adjustment assembly on the side near the lifting plate 23. The roller 2543 is located on the moving path of the contact plate 2541, and the connecting rod 2542 will not hinder the normal movement of the contact plate 2541 during its movement. When the operator presses down on the paint bucket 5 and confines it within the limiting mechanism 2, the bottom of the paint bucket 5 contacts the top of the lifting plate 23. The downward pressure on the lifting plate 23 causes the adjusting plate 24 to move, and the positioning plate 25 mounted on the lifting plate 23 moves accordingly. The positioning plate 25 causes the two positioning holes 251 to move downwards. The guide block in the lower positioning hole 251 contacts the conical slope of one end of the positioning rod 252. Therefore, during the downward movement of the lifting plate 23, the guide block can push the positioning rod 252 out of the positioning hole 251. After being pushed out, the positioning rod 252 will be on one side of the positioning plate 25. When the positioning rod 252 is pushed out of the positioning hole 251, it will cause the sliding piece 2531 to slide within the fixed cylinder 253. The sliding sliding piece 2531 will compress the second spring. The second spring stores elastic potential energy in the fixed cylinder 253. When the operator continues to apply downward pressure, the lifting plate 23 and the positioning plate 25 continue to move downward. When the positioning rod 252 is aligned with the positioning plate 25 in the upper positioning hole 251, the second spring will release elastic potential energy instantly and drive the slider 2531 and the positioning rod 252 to move back to reset. The second spring will drive the pointed end of the positioning rod 252 to insert into the upper positioning hole 251. After the positioning rod 252 passes through the positioning hole 251, it can limit the movement of the positioning plate 25. In addition, the positioning plate 25 is fixedly connected to the lifting plate 23, so it can be locked together with the lifting plate 23. At this time, the sliding between the two sets of gears and racks can be limited by fixing the lifting plate 23. Therefore, the two limiting plates 22 can firmly clamp and limit the paint bucket 5. After the paint bucket 5 is restricted to the chain plate by the limiting plate 22, the chain plate conveyor belt 4 can be started. The chain plate conveyor belt 4 will smoothly drive the paint bucket 5 to the filling area under the action of the limiting plate 22. After reaching the filling area, the paint bucket 5 can be filled by the filling equipment set in the filling area. At this time, the next paint bucket 5 to be filled can be placed in the limiting mechanism 2 at the front end of the mounting frame 1. After the filling equipment completes the filling task for paint bucket 5 in the filling area: The chain conveyor belt 4 can be restarted, and its movement will continue to drive the filled paint buckets 5 towards the end of the chain conveyor belt 4, thereby transporting the filled paint buckets 5 to the next material handling area. When the paint bucket 5 is at the end of the chain conveyor belt 4, the paint bucket 5 to be filled will move to the filling area under the conveyor belt 4: Meanwhile, the slope of the contact plate 2541 on the end limiting mechanism 2 will contact the surface of the roller 2543. The roller 2543 is installed at the end of the mounting frame 1 via the connecting rod 2542. The contact between the roller 2543 and the slope of the contact plate 2541 will gradually stretch the positioning rod 252. When the roller 2543 contacts the middle section of the contact plate 2541, the pointed tip of the positioning rod 252 will completely slide out of the positioning hole 251. During the movement of the positioning rod 252, the second spring continues to store elastic potential energy. At this time, the positioning rod 252 can be pulled out from the positioning hole 251 at the upper end, thereby... The positioning rod 252 automatically releases the lock on the positioning plate 25 and the lifting plate 23. At this time, the paint bucket 5 can be taken out from the working groove 21, the upper surface of the lifting plate 23, and the two limit plates 22. The first spring will release its elastic potential energy first, driving the adjusting plate 24, the lifting plate 23 and the positioning plate 25 to move upward. The retaining ring 244 can limit the upward stroke. The positioning hole 251 at the lower end will be on one side of the pointed end of the positioning rod 252. The lifting plate 23 will slide out from the telescopic groove 211 again, waiting for the chain plate conveyor belt 4 to transport the limiting mechanism 2 of this area to the initial bucket feeding area for reuse. After the paint bucket 5 in the filling area is filled, the limiting mechanism 2 at the end of the mounting frame 1 removes the paint bucket 5. At this time, the movement of each component of the limiting mechanism 2 at the end of the mounting frame 1 is as follows: The chain conveyor belt 4 will continue to drive the contact plate 2541 to press against the roller 2543. The contact plate 2541 will continue to move away from the positioning plate 25 due to the pressing against the roller 2543. At this time, the positioning rod 252 in the fixed cylinder 253 will press the second spring through the sliding plate 2531. At this time, the roller 2543 in the middle of the contact plate 2541 will press against the contact plate 2541 again as the chain conveyor belt 4 starts. When the roller 2541 and the contact plate 2543 come into contact, they will slide relative to each other. The contact plate 2541 will gradually separate from the roller 2543. When the roller 2543 and the contact plate 2541 are in the extreme position, the ends of the roller 2543 and the contact plate 2541 are in contact, and the chain conveyor belt 4 has not stopped moving. At this time, the roller 2543 and the contact plate 2541 will disengage. At this time, the second spring releases elastic potential energy and drives the positioning rod 252, the connecting plate 254 and the contact plate 2541 to reset. The pointed tip of the positioning rod 252 will slide out from the positioning hole 251 at the lower end of the positioning plate 25, thereby fixing the reset positioning plate 25 and the lifting plate 23. The quick-adjustment assembly includes a connecting cylinder 26 and a guide rod 261. An adjusting plate 24 has a guide hole corresponding to the position of the guide rod 261. One end of the guide rod 261 slides through the wall of the guide hole, and the other end is fixedly connected to a lifting seat 262. The inner wall of the connecting cylinder 26 is slidably connected to the outer peripheral wall of the guide rod 261. The lower end of the connecting cylinder 26 is fixedly connected to the adjusting plate 24. An adjusting plate is fixedly connected to the lower end of the outer peripheral wall of the guide rod 261, and the adjusting plate is slidably connected to the inner cavity of the connecting cylinder 26. A third spring is sleeved on the outer peripheral wall of the guide rod 261, and both ends of the third spring are fixedly connected to the adjusting plate and the side of the lifting seat 262, respectively. An abutment cylinder 263 is rotatably connected to the side wall of the lifting seat 262. A connecting groove 27 is provided on the side of a chain plate adjacent to the lifting seat 262. A support plate 271 is fixedly connected to the bottom wall of the connecting groove 27. A through hole is provided on the side of the support plate 271. A steel rope 273 slides through the inner wall. One end of the steel rope 273 is fixedly connected to a handle 275. A guide tube 272 is fixedly connected to the support plate 271 at the corresponding through hole. The steel rope 273 slides in contact with the inner cavity of the guide tube 272 and passes through the inner cavity of the guide tube 272. One end of the steel rope 273 is fixedly connected to a handle 275. Two slots are opened on the side of the handle 275 near the support plate 271. A protrusion is fixedly connected to the support plate 271 at the position corresponding to the two slots. The other end of the steel rope 273 is fixedly connected to a lifting frame 274. The lifting frame 274 is fixedly connected to the lifting seat 262. A connecting ring 255 is fixedly connected to the outer peripheral wall of the pointed cone end of the two positioning rods 252. A round rod is fixedly connected to one end of the outer peripheral wall of the connecting ring 255. A quick-adjusting rod 2551 is fixedly connected to the arc surface of the round rod. The quick-adjusting rod 2551 is a bent rod, and the inner angle of the bend is an acute angle. If, during the filling process, it is discovered that the opening of paint bucket 5 is not aligned with the filling gun of the filling equipment, and the angle of the opening of paint bucket 5 needs to be adjusted, the operator can directly pull the handle 275 inside the connecting groove 27. The movement of handle 275 will cause the steel cable 273 to move within the through hole of the support plate 271. The steel cable 273 will then pull the lifting frame 274 upward through the guide cylinder 272. The upward movement of the lifting frame 274 will cause the lifting seat 262 to move. The lifting seat 262 will then pull the guide rod 261 within the connecting cylinder 26. The guide rod 261 will slide within the guide hole wall on the adjusting plate 24. Simultaneously, the guide rod 261 will cause the adjusting plate to move upward, compressing the third spring. The compression of the third spring will store elastic potential energy. When the lifting seat 262 pulls the guide rod 261, it will cause the abutment cylinder 263 inside to contact one side of the quick-adjustment rod 2551. The abutment cylinder 263 will then push the quick-adjustment rod 2551 upward. Because the quick-adjustment lever 2551 is inclined, when the steel rope 273 is pulled, the two quick-adjustment levers 2551 will drive the two sets of connecting rings 255 and positioning rods 252 to move away from each other. Therefore, the positioning rod 252 can slide out of the current positioning hole 251. At this time, the operator can pull the paint bucket 5 upward in the two limit plates 22 and adjust the bucket opening angle by rotating the paint bucket 5. The operator can release the handle 275, and the steel rope 273 will release the contact effect between the connecting cylinder 26 and the quick-adjustment lever 2551. The third spring releases elastic potential energy and pushes the adjusting plate and the lifting seat 262 downward to reset. With the help of the third spring, the angle of the handle 275 can be adjusted in the connecting groove 27, and the slot installed on the handle 275 will contact the protrusion on the support plate 271. Under the action of the protrusion and the slot engaging, the stability of the handle 275 on the support plate 271 and in the connecting groove 27 can be improved. After adjusting the angle of the paint bucket 5 opening, pressing down on the paint bucket 5 will again secure it to the chain plate. like Figures 17-23 As shown, the material guiding mechanism 3 includes a support frame plate 31, which is fixedly connected to the mounting frame by bolts. A motor 32 is fixedly connected to the side of the support frame plate 31 away from the mounting frame. The output end of the motor 32 is fixedly connected to a drive rod 321. A threaded section is provided at the lower end of the outer peripheral wall of the drive rod 321. A lifting arm 323 is connected to the threaded external thread of the drive rod 321. A guide arm 324 is slidably provided through the inner wall of the lifting arm 323. The upper end of the guide arm 324 is fixedly connected to the top wall of the support frame plate 31. A support rod 322 is rotatably connected to one end of the drive rod 321 through a bearing. A guide hole is provided on the lifting arm 323 corresponding to the position of the support rod 322. The guide hole is slidably connected to the outer peripheral wall of the support rod 322. One end of the support rod 322 is fixedly connected to the top wall of the support frame plate 31. A funnel 33 is fixedly connected to one side of the lifting arm 323. A detection component is provided on the outer peripheral wall of the funnel 33. When the motor 32 starts, it can drive the drive rod 321 to move through the output end. The drive rod 321 will rotate on the support rod 322 under the action of the bearing. The movement of the drive rod 321 will drive the lifting arm 323 to move downward along the angle of the guide arm 324, thereby driving the funnel 33 to move towards the position of the mouth of the paint bucket 5. The filling equipment is installed on the side of the mounting frame 1. The nozzle of the filling gun is directly above the funnel 33. During filling, the filling gun descends to align the nozzle with the mouth of the bucket. The filling gun is equipped with a driving element, which can drive the valve core rod inside the filling gun to move upward to open the channel. The paint enters the inlet and internal flow channel of the filling gun through the outlet of the paint storage device and the paint pipe. The nozzle sends the paint into the funnel 33. The paint flows down the funnel 33 into the paint bucket 5. After the set amount is reached, the valve core rod moves down and the plug closes the nozzle. The detection assembly includes two fixing blocks 34, which are symmetrically fixed at both ends of the outer peripheral wall of the funnel 33. A micro switch 341 is fixedly connected to one side of the fixing block 34. A fixing plate 342 is fixedly connected to the lower end of the funnel 33. The fixing plate 342 is located below the micro switch 341. The fixing plate 342 has detection holes corresponding to the positions of the two micro switches 341. An outer sleeve is fixedly installed at the bottom of the detection hole. A detection rod 343 is slidably installed inside the outer sleeve. The upper end of the detection rod 343 passes through the detection hole and is fixedly connected to a trigger block. An annular plate is fixedly sleeved on the outside of the detection rod 343. The annular plate is slidably installed in the inner cavity of the outer sleeve. A fourth spring is sleeved on the outside of the detection rod 343. The two ends of the fourth spring abut against the fixing plate 342 and the annular plate, respectively. The fourth spring applies a downward elastic force to the annular plate, so that the annular plate drives the detection rod 343 to always maintain a downward trend. A spherical block is integrally formed at the lower end of the detection rod 343. A sealing assembly is installed at the lower end of the inner cavity of the funnel 33. The micro switch 341 is a normally closed switch, and it is connected in series in the start / stop circuit of the filling gun of the filling equipment. Under normal circumstances, the micro switch 341 is not triggered and is in the connected state. When the button of the micro switch 341 is pressed and triggered, the micro switch 341 is opened, thus disconnecting the circuit connected to it. The sealing assembly includes a valve seat fixedly installed at the lower end of the inner cavity of the funnel 33. A closing ball valve 365 is rotatably installed in the inner cavity of the valve seat. An adjusting rod 36 is symmetrically fixedly connected to the side of the closing ball valve 365. The adjusting rod 36 passes through the valve seat and the funnel 33 in sequence and extends to the outside. The adjusting rod 36 is rotatably connected to the valve seat and the funnel 33 respectively. A discharge port is opened through the side of the closing ball valve 365. Two adjusting rods 36 are fixedly connected to adjusting gears 361 at their opposite ends. A positioning rod is rotatably connected to the side of the adjusting gear 361 away from the adjusting rod 36 via a connecting bearing. One end of the positioning rod is fixedly connected to the bottom of a fixed disk 342. Adjusting racks 362 mesh with the teeth of the adjusting gears 361. A through slot is provided on the fixed disk 342 corresponding to the position of the adjusting racks 362. The adjusting racks 362 are slidably connected to the through slot. The lower ends of both adjusting racks 362 are fixedly connected to a force-bearing disk 366. The upper ends of the adjusting racks 362 are fixed by a bracket. Two adjusting rings 363 are connected. A cylinder rod is slidably inserted into the inner wall of the adjusting ring 363. A reset cylinder 364 is sleeved on the outside of the adjusting ring 363. The cylinder rod is set in the inner cavity of the reset cylinder 364. The lower end of the cylinder rod is fixedly connected to the fixed plate 342. A fifth spring is sleeved on the outer peripheral wall of the cylinder rod. The two ends of the fifth spring are fixedly connected to the top wall of the adjusting ring 363 and the reset cylinder 364, respectively. The fifth spring applies a downward elastic force to the adjusting ring 363, so that the adjusting ring 363 always maintains a downward movement tendency. The adjusting ring 363 drives the adjusting rack 362 to maintain a downward movement tendency through the bracket. The side of the reset cylinder 364 has a vertical groove for the bracket to pass through, and the bracket is slidably connected to the vertical groove. A trigger rod 351 is fixedly connected to one side of the lifting arm 323. A proximity switch 35 is fixedly connected to the side of the guide arm 324 at the position corresponding to the trigger rod 351. The proximity switch 35 is connected in series with the driving element of the filling gun. A control device 37 is fixedly connected to one end of the guide arm 324. The control device 37 is electrically connected to the proximity switch 35. A laser beam sensor group 38 is fixedly connected to the side of the support frame plate 31. The proximity switch 35 is a normally open switch, and the proximity switch 35 is connected in series in the control circuit of the filling gun drive element. Under normal circumstances, when the lifting arm 323 has not descended to the set position, the trigger rod 351 has not approached the proximity switch 35. At this time, the proximity switch 35 is in the open state, the drive element is not energized, and the valve core rod can keep the feeding channel closed. When the lifting arm 323 lowers the funnel 33 to the position, the trigger rod 351 moves to the trigger range of the proximity switch 35. The proximity switch 35 is triggered by the trigger rod 351 to close, thereby connecting the control circuit of the drive element. After the drive element is energized, it drives the valve core rod to move upward, opens the feeding channel, and starts filling. During the movement of funnel 33 toward the mouth of paint bucket 5, if the position of the bucket mouth shifts: Motor 32 drives funnel 33 to move towards the mouth of paint bucket 5. At this time, the spherical block at the lower end of detection rod 343 will be misaligned with the mouth of the bucket, causing detection rod 343 to be unable to extend into the mouth of the bucket. During the downward movement of detection rod 343, the spherical block at the lower end will contact the surface of the mouth of paint bucket 5. The spherical block is blocked by the upper end of paint bucket 5 and cannot move further down. At this time, detection rod 343 and trigger block also cannot move down. Funnel 33 drives reset cylinder 364 to continue to move down through fixed plate 342. At this time, fixed plate 342 and annular plate cooperate to compress the fourth spring. At the same time, funnel 33 moves down and drives micro switch 341 to move down synchronously through fixed block 34. At this time, micro switch 341 gradually approaches trigger block. The button of micro switch 341 presses against trigger block and micro switch 341 is triggered to disconnect the circuit of filling equipment. At this time, filling equipment cannot operate normally, stops the extension and retraction of filling gun, and suspends filling work. When a reset is required, the motor 32 is first reversed to raise the funnel 33. After the funnel 33 rises, it moves the micro switch 341 away from the trigger block until the spherical block moves away from the upper surface of the paint bucket 5 opening. The fourth spring will push the detection rod 343 to reset through the annular plate, causing the trigger block and the micro switch 341 to separate. The detection rod 343 will then be back in the ready-to-trigger state. After the operator adjusts the angle of the paint bucket 5 opening, the filling task can be continued by manually operating the control device 37. During the movement of funnel 33 toward the mouth of paint bucket 5, assuming no shift in the position of the bucket mouth: Motor 32 drives funnel 33 to move towards the opening of paint bucket 5. The lower end of funnel 33, together with the lower end of detection rod 343, enters the opening of paint bucket 5. The movement of motor 32 will drive lifting arm 323 to move downward through drive rod 321. The movement of lifting arm 323 will drive trigger rod 351 to move downward and contact proximity switch 35. Trigger rod 351 will trigger proximity switch 35. The triggering of proximity switch 35 will transmit the signal that funnel 33 has reached the position to control device 37. Control device 37 will control filling gun to descend to perform filling task. Under normal conditions, the outlet end of the ball valve is retracted into the valve seat, and the lower end of the funnel 33 is closed to prevent the paint residue in the funnel 33 from dripping downwards. During normal filling, the lower end of the funnel 33 is aligned with the mouth of the paint bucket 5. The funnel 33 drives the force plate 366 to move downward. When the force plate 366 comes into contact with the upper surface of the paint bucket 5, the adjusting rack 362 can no longer move downward. The funnel 33 will drive the adjusting rod 36 and the adjusting gear 361 to continue moving downward through the fixed plate 342, so that the adjusting gear 361 rolls downward along the adjusting rack 362 until the lower end of the funnel 33 extends into the mouth of the bucket, completing the connection. During this process, the adjusting gear 361 rolls downward along the adjusting rack 362 for a certain distance. At this time, the adjusting gear 361 drives the adjusting rod 36 to rotate 90 degrees. The adjusting rod 36 drives the closed ball valve 365 to rotate 90 degrees, so that the outlet of the ball valve rotates to the vertical position. The lower end of the funnel 33 opens, and the outlet connects the inner cavity of the funnel 33 with the inner cavity of the paint bucket 5. During the descent of the fixed plate 342, the fixed plate 342 drives the reset cylinder 364, the cylinder rod, and the fifth spring to move continuously downward. At this time, the adjusting ring 363 and the adjusting rack 362 cannot move downward. The reset cylinder 364 and the adjusting ring 363 cooperate to squeeze the fifth spring. The fifth spring stores elastic potential energy. After the feeding ends and the funnel 33 rises, the fifth spring releases elastic potential energy and drives the adjusting rack 362 to reset through the adjusting ring 363. During the upward movement of the fixed plate 342, the adjusting rack 362 remains stationary. At the same time, the fixed plate 342 drives the adjusting gear 361 to roll in the opposite direction along the adjusting rack 362. Through the adjusting rod 36, the closed ball valve 365 is reset. The outlet of the closed ball valve 365 retracts into the valve seat to seal the lower end of the funnel 33. At this time, if the fixed plate 342 continues to move upward, it will drive the adjusting rack 362 and the force plate 366 to move upward synchronously to reset. The sealing assembly will also activate if the mouth of paint bucket 5 is not aligned with funnel 33.

[0026] Its overall working principle is as follows: The initial state of the limiting mechanism 2 is as follows: the two limiting plates 22 are far apart from each other in the working groove 21, the pointed cone end of the positioning rod 252 is inserted into the positioning hole 251 at the lower end of the positioning plate 25, locking the lifting plate 23 in the low position in the telescopic groove 211, and the upper end of the lifting plate 23 extends out from the telescopic groove 211. The operator places the paint bucket 5 on the lifting plate 23 in the working slot 21, so that the bottom of the paint bucket 5 contacts the lifting plate 23 and presses the paint bucket 5 down. The lifting plate 23 will slide down along the telescopic slot 211 under the force, thereby driving the lifting racks 231 on both sides to descend synchronously. The lifting racks 231 drive the connecting gear 232 and the transmission gear 233 to rotate. The transmission gear 233 drives the sliding rack 221 to slide along the guide strip 222 toward the middle. The sliding rack 221 drives the limiting plate 22 to move closer to the paint bucket 5. The rubber contact strip 223 on the limiting plate 22 elastically abuts against the outer peripheral wall of the paint bucket 5, clamping and positioning the paint bucket 5. During the downward movement of the lifting plate 23, the lifting plate 23 drives the adjusting plate 24 to slide downward, and the first spring is stretched to store potential energy. At the same time, the lifting plate 23 drives the positioning plate 25 to move downward. The guide block in the positioning hole 251 at the lower end of the positioning plate 25 contacts the slope of the pointed end of the positioning rod 252, pushing the positioning rod 252 out of the positioning hole 251. The positioning rod 252 drives the sliding piece 2531 to compress the second spring to store potential energy. When the positioning plate 25 continues to move downward until the upper positioning hole 251 is aligned with the positioning rod 252, the second spring releases potential energy to push the positioning rod 252 into the upper positioning hole 251, thereby locking the lifting plate 23 and keeping the limiting plate 22 clamped to the paint bucket 5. After the paint bucket 5 is clamped, the chain conveyor belt 4 starts and smoothly transports the paint bucket 5 to the filling area for filling. After filling, the chain conveyor belt 4 can continue to move the paint bucket 5 to the end. When the limiting mechanism 2 moves to the end of the chain conveyor belt 4, the slope of the contact plate 2541 contacts the roller 2543. The slope of the contact plate 2541 slides along the surface of the roller 2543 and gradually pulls the positioning rod 252 out of the positioning hole 251, thereby releasing the lock on the lifting plate 23. At this time, the filled paint bucket 5 can be removed from the working groove 21. The first spring releases potential energy to drive the lifting plate 23 to reset upward. At the same time, the slope of the contact plate 2541 continues to slide on the surface of the roller 2543 until the contact plate 2541 and the roller 2543 are separated. The second spring resets and drives the positioning rod 252 to re-insert into the positioning hole 251 at the lower end of the positioning plate 25, fixing the lifting plate 23 in the initial state, waiting for the next use.

[0027] When the angle of the paint bucket 5 opening is misaligned with the nozzle of the filling gun, and the angle of the paint bucket 5 opening needs to be adjusted, the operator pulls the handle 275, which pulls the lifting frame 274 and the lifting seat 262 upward via the steel cable 273. The lifting seat 262 drives the abutment cylinder 263 to push the quick-adjustment rod 2551 to rotate. The quick-adjustment rod 2551 drives the two sets of connecting rings 255 and the positioning rod 252 to move outward, so that the positioning rod 252 exits from the positioning hole 251, releasing the lock on the lifting plate 23. At this time, the operator can lift the paint bucket 5 upward between the two limit plates 22 and rotate it to adjust the opening angle. After the adjustment is completed, the handle 275 is released, and all parts are reset to lock the paint bucket 5 again.

[0028] The material guiding mechanism 3 is activated after the paint bucket 5 is conveyed to the filling area. The motor 32 drives the drive rod 321 to rotate. The drive rod 321 drives the lifting arm 323 to move downward along the guide arm 324 through the threaded section. The lifting arm 323 drives the funnel 33 to descend to the position of the mouth of the paint bucket 5. When the lower end of the funnel 33 deviates from the position of the mouth of the bucket during the descent, the spherical block at the lower end of the detection rod 343 will contact the edge of the mouth of the bucket and will not be able to enter the mouth. At this time, the funnel 33 continues to descend, and the micro switch 3 is activated through the fixed plate 342. 41 moves downwards, and the detection rod 343 and the trigger block at its upper end are blocked by the barrel opening and remain stationary. The trigger block will make squeezing contact with the button of the micro switch 341, and the micro switch 341 will be triggered, disconnecting the circuit of the filling equipment and stopping the extension and retraction of the filling gun. After the operator adjusts the barrel opening angle, the motor 32 rotates in the opposite direction to drive the funnel 33 to rise. The fourth spring pushes the detection rod 343 to reset, the micro switch 341 returns to the normally closed state, the circuit of the filling equipment is reconnected, and the filling task can be restarted. If the bucket opening is in the correct position during the descent of the funnel 33, the lower end of the funnel 33, together with the detection rod 343, smoothly enters the inside of the paint bucket 5. When the lifting arm 323 descends to the set position, the trigger rod 351 on the lifting arm 323 moves into the trigger range of the proximity switch 35, and the proximity switch 35 is triggered to close. Since the proximity switch 35 is connected in series in the control circuit of the filling gun drive element, the drive element is energized after the circuit is turned on. The drive element drives the valve core rod to move up to open the feeding channel, and the filling gun starts filling. During the descent of the funnel 33, the force plate 366 contacts the upper surface of the paint bucket 5 and is blocked by the bucket opening, preventing it from moving further down. As the funnel 33 continues to descend, the adjusting rack 362 and the fixed plate 342 move relative to each other. The adjusting rack 362 drives the adjusting gear 361 to rotate. The adjusting gear 361 drives the closed ball valve 365 to rotate 90 degrees through the adjusting rod 36, rotating the ball valve's outlet from a horizontal closed state to a vertical open state, so that the inner cavity of the funnel 33 is connected to the inner cavity of the paint bucket 5. The filling gun injects water-based paint into the bucket through the funnel 33. After the filling is completed, the funnel 33 rises, the fixed plate 342 drives the reset cylinder 364 to move upward, the fifth spring releases potential energy to drive the adjusting rack 362 to reset, the adjusting rack 362 drives the adjusting gear 361 to rotate in the opposite direction, and through the adjusting rod 36 drives the closed ball valve 365 to rotate in the opposite direction by ninety degrees to reset, so that the discharge port of the ball valve retracts into the valve seat, sealing the lower end of the funnel 33 to prevent residual paint from dripping.
