Description

Technical Field

[0001] This invention relates to the field of non-stick cookware technology, and in particular to an aluminum non-stick cookware and its production equipment. Background Technology

[0002] Aluminum non-stick pans are pans with an aluminum base and a non-stick coating evenly sprayed inside and out. Combining the good heat conductivity of aluminum with the non-stick coating properties, they are very popular among consumers. However, uneven coating often occurs during the non-stick coating process, especially on the curved outer wall. When the rotation speed and spraying speed are the same for pans of different diameters, the coating thickness of the larger diameter pans is less than that of the smaller diameter pans.

[0003] Meanwhile, the spraying speed is the same on the upper large diameter and the lower small diameter of the same pot body. Therefore, the thickness of the coating on the circumference of the large diameter is less than the thickness of the coating on the circumference of the small diameter, resulting in different coating thicknesses on the surface of the pot body, which affects the heat conduction performance of the pot body. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an aluminum non-stick pan and its production equipment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a production equipment for aluminum non-stick pans, comprising an aluminum non-stick pan, the pan body being uniformly coated with a coating on its circumference, and production equipment for coating application. The production equipment includes a conveyor line, a telescopic device, and a spraying device. The conveyor line includes a sliding track, a pan body clamp, and a rotating motor. The pan body is clamped in the pan body clamp, which is guided and slidably mounted on the sliding track. A rotating shaft is mounted on the pan body clamp, and a first gear is mounted at the bottom of the rotating shaft. The rotating motor is mounted on the side of the sliding track, and a second gear is mounted on the motor shaft. The pan body clamp slides on the sliding track, and the first gear meshes with the second gear. The conveyor line is used for continuous conveying of the pan body. The telescopic device includes a telescopic cylinder, a sliding frame, and a base frame. The base frame is mounted on the sliding track of the conveyor line, the telescopic cylinder is mounted on the base frame, the sliding frame is guided and slidably mounted on the base frame, and the telescopic rod of the telescopic cylinder is connected to the sliding frame. The spraying device includes a spray gun head, a spacer sleeve, and a speed regulating device. The spray gun head is guided and slidably mounted on a sliding frame, and the spacer sleeve is guided and slidably mounted on the spray gun head. A first electromagnet is mounted on the spray gun head, and an adsorption block is mounted on the spacer sleeve. A first elastic element is positioned between the first electromagnet and the adsorption block. When the first electromagnet is energized, it can attract the adsorption block, causing the spacer sleeve to extend beyond the front end of the spray gun head. The speed regulating device includes a sliding rheostat, which is mounted on the sliding frame, and a sliding block is mounted on the spray gun head. When the conveyor belt moves the pot clamp to the spraying area, the first gear can mesh with the second gear, the first electromagnet is energized, the spacer sleeve extends forward, and the telescopic device pushes the sliding frame to move towards the pot clamp. The spacer sleeve stops moving forward when it touches the side of the pot, and the sliding frame continues to move forward. The sliding block slides on the sliding rheostat, which is connected to the rotating motor circuit to change the rotation speed of the rotating motor.

[0006] Its beneficial effect is that when spraying begins, the maximum diameter of the pot is automatically identified, and the rotation speed of the pot is automatically adjusted during spraying. This ensures that the linear velocity at the maximum diameter is basically the same for pots of different sizes during spraying, thereby improving the uniformity of the coating on the surface of the pot and ensuring that the coating thickness on the surface of pots of different sizes is basically the same.

[0007] In the above scheme, preferably, the sliding block slides towards the sliding frame, and the larger the resistance value of the sliding rheostat connected to the circuit, the slower the rotation speed of the rotating motor.

[0008] In the above scheme, preferably, the sliding frame is equipped with a brake pad. When the telescopic cylinder is fully extended, the brake pad clamps and locks the spray gun head, while simultaneously controlling the first electromagnet to be de-energized.

[0009] Its beneficial effect is that it allows the spray gun head to have an optimal spraying distance during spraying.

[0010] In the above-mentioned scheme, preferably, a feeding device is also included. The feeding device includes a feeding box and an inclined track. The feeding box and the inclined track are set on the base frame. An inclined surface is provided on the inclined track, and a flexible hose is laid on the inclined surface. One end of the flexible hose is connected to the feeding box, and the other end is connected to the feed inlet at the rear end of the spray gun head. A roller is provided at the rear end of the spray gun head. The roller presses against the flexible hose. When the spray gun head moves forward, it drives the roller to move forward. At the same time, in cooperation with the inclined surface, the cross-sectional area of ​​the flexible hose at the position where the roller presses against the spray gun head gradually decreases as the spray gun head moves forward.

[0011] In the above scheme, preferably, the sliding frame is uniformly provided with multiple sets of spray gun heads and inclined rails in the vertical direction.

[0012] In the above scheme, preferably, the telescopic cylinder is fully extended, and the front end of the spray gun head can reach the axis of rotation. At this time, the roller also moves to the front end and cooperates with the inclined surface to completely seal the internal pipe of the hose.

[0013] The beneficial effects of this invention are as follows: This invention provides an aluminum non-stick pan and its production equipment, which can automatically identify pans of different diameters and allocate speeds to pans of different diameters, so that the linear velocity at the maximum diameter of pans of the same size is basically consistent during spraying, thereby improving the uniformity of the coating on the pan surface. The coating thickness on the surface of pans of different sizes is basically consistent. At the same time, the flow rate of each nozzle is automatically adjusted according to the curvature of the pan, so that the coating on the sides of the pans of different diameters is basically consistent at the same rotation speed, further improving the uniformity of the coating on the pan surface.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-7 An aluminum non-stick pan and its production equipment are disclosed. The non-stick pan includes a pan body 1, which is uniformly coated with a coating on its circumference. The production equipment includes a production line 2, a telescopic device 3, a spraying device 4, and a feeding device 5. The production line 2 includes a sliding track 21, a pan body clamp 22, a rotating motor 23, and a locking device. The pan body clamp 22 includes a rotating shaft 221 and a load-bearing guide block 223. The load-bearing guide block 223 is slidably mounted on the sliding track 21. The rotating shaft 221 is rotatably mounted within the load-bearing guide block 223. A tensioning disc 224 is provided at the upper end of the rotating shaft 221 for clamping the pan body 1, and a first gear 222 is provided at the lower end. A speed-multiplying chain 211 is provided within the sliding track 21. The movement of the speed-multiplying chain 211 can drive the load-bearing guide block 223 to move on the sliding track 21. The rotating motor 23 is located on one side of the sliding track 21. Furthermore, a second gear 231 is provided on the rotating shaft of the rotating motor 23, and a locking device is provided on one side of the sliding rail 21 opposite the rotating motor 23.

[0022] When the double-speed chain 211 drives the load-bearing guide block 223 to the rotating motor 23, the locking device automatically extends and locks the load-bearing guide block 223. At this time, the second gear 231 on the rotating motor 23 meshes with the first gear 222.

[0023] The telescopic device 3 includes a telescopic cylinder 31, a sliding frame 32, and a base frame 33. The base frame 33 is disposed on the side of the sliding track 21, the telescopic cylinder 31 is disposed on the base frame 33, the sliding frame 32 is guided and slidably disposed on the base frame 33, and the telescopic rod 311 of the telescopic cylinder 31 is connected to the sliding frame 32. The telescopic rod 311 moves back and forth, causing the sliding frame 32 to move back and forth.

[0024] The spraying device 4 includes a spray gun head 41, a limiting sleeve 42, and a speed regulating device 43. The spray gun head 41 is guided and slidably mounted on a sliding frame 32. A second elastic element 44 is sleeved on the spray gun head 41. A countersunk hole is provided on the sliding frame 32. One end of the second elastic element 44 abuts against the bottom surface of the countersunk hole in the sliding frame 32, and the other end abuts against the limiting block of the spray gun head 41. The limiting sleeve 42 is slidably mounted at the front end of the spray gun head 41. A first electromagnet 411 is provided on the spray gun head 41. An adsorption block 421 is provided on the limiting sleeve 42. A first elastic element 422 is provided between the first electromagnet 411 and the adsorption block 421, and a countersunk hole is provided on the adsorption block 421.

[0025] When the first electromagnet 411 is energized, it can attract the adsorption block 421, thereby causing the limiting sleeve 42 to extend beyond the front end of the spray gun head 41. At the same time, the first elastic element 422 is completely submerged in the countersunk hole on the adsorption block 421. The speed regulating device 43 is a sliding rheostat 431, which is set on the sliding frame 32. The spray gun head 41 is provided with a sliding block 412. When the spray gun head 41 slides relative to the sliding frame 32, the sliding block 412 moves on the sliding rheostat 431. The sliding rheostat 431 is connected to the circuit of the rotating motor 23. The more the sliding block 412 slides towards the sliding frame 32, the greater the resistance of the sliding rheostat 431 connected to the circuit, thereby slowing down the rotation speed of the rotating motor 23.

[0026] Brake pads 321 are installed on the sliding frame 32 and located on both sides of the spray gun head 41. When the brake pads 321 are clamped, the spray gun head 41 is locked. When the conveyor belt 2 moves the pot body clamp 22 to the spraying area, the locking device locks the pot body clamp 22, and the first gear 222 can mesh with the second gear 231. At this time, the spray gun head 41 is directly facing the axis of the rotating shaft 221. At the same time as the locking device locks the pot body clamp 22, the first electromagnet 411 is energized, causing the limiting sleeve 42 to extend forward. At this time, the telescopic cylinder 31 starts to work, pushing the sliding frame 32 to move forward. The spray gun head 41 moves towards the pot body clamp 22. After the front end of the limiting sleeve 42 touches the side of the pot body 1, the spray gun head 41 stops moving forward. At this time, the telescopic cylinder 31 continues to move forward, so that the sliding frame 32 moves relative to the spray gun head 41, and the sliding block 412 moves relative to the rear end of the sliding rheostat 431. When the telescopic cylinder 31 is fully extended, the brake pad 321 clamps and locks the spray gun head 41. At the same time, the first electromagnet 411 is de-energized, and the limiting sleeve 42 retracts under the action of the first elastic element 422. At this time, the spray gun head 41 maintains a suitable spraying distance from the pot body 1.

[0027] Depending on the diameter of the pot body 1, the position where the spray gun head 41 stops is also different. The larger the diameter of the pot body 1, the earlier the spray gun head 41 stops moving forward, that is, the greater the sliding distance of the sliding block 412. This results in a greater resistance connected to the rotating motor 23, which in turn makes the rotation speed slower during spraying. This ensures that the linear velocity of the edge of the pot body 1 remains basically consistent, thereby improving the uniformity of the coating on the surface of the pot body.

[0028] The feeding device 5 includes a feeding box 51 and an inclined track 52. The feeding box 51 and the inclined track 52 are mounted on the base frame 33. An inclined surface 521 is provided on the inclined track 52, and a flexible hose 522 is laid on the inclined surface 521. One end of the flexible hose 522 is connected to the feeding box 51, and the other end is connected to the rear feed port of the spray gun head 41. A roller 413 is provided at the rear end of the spray gun head 41, and the roller 413 presses against the flexible hose 522. Multiple sets of spray gun heads 41 and inclined tracks 52 are evenly arranged in the vertical direction of the sliding frame 32.

[0029] The diameter of the rim of the ordinary pot body 1 is the largest. Therefore, a sliding rheostat 431 is provided on the side of the bottom spray gun head 41 so that the bottom end contacts the part with the largest diameter of the pot body 1, thereby determining the rotation speed of the rotating motor 23.

[0030] As the telescopic cylinder 31 extends forward, the spray gun head 41 moves forward, thereby driving the roller 413 to move forward. The further forward the roller 413 moves, the smaller the distance between it and the inclined surface 521 becomes, thus making the cross-sectional area of ​​the roller 413 pressing against the hose 522 smaller. When the spray gun head 41 is fully extended, the roller 413 and the inclined surface 521 cooperate to completely seal the internal pipe of the hose 522, that is, no paint is sprayed out at the spray gun head 41 at this time.

[0031] Multiple sets of spray gun heads 41 and inclined rails 52 are evenly arranged in the vertical direction of the sliding frame 32. Therefore, the spray gun head 41 at each vertical position will stop at different positions according to the curvature of the side wall of the pot body 1. The smaller the distance between the spray gun head 41 and the rotating shaft 221, the smaller the flow section of the hose 522 connected to it. As a result, the flow rate of the spray gun head 41 at the larger diameter position of the pot body 1 is greater than that of the spray gun head 41 at the smaller diameter position. This ensures that the paint sprayed on the large and small diameters of the side of the pot body 1 is basically consistent at the same rotation speed.

[0032] The spray gun head 41 that does not touch the pot body 1 will automatically shut off and will not perform spraying operations.

[0033] Its working principle or usage method is as follows:

[0034] When the batch of pot body 1 begins to be sprayed, the double speed chain 211 starts to rotate, driving the first load-bearing guide block 223 to move to the rotating motor 23. The laser detection device detects that the workpiece has entered the station, thereby controlling the locking device to automatically extend and lock the load-bearing guide block 223. At this time, the second gear 231 on the rotating motor 23 meshes with the first gear 222.

[0035] At this time, the spray gun head 41 is aligned with the axis of the rotating shaft 221. While the locking device locks the pot clamp 22, the first electromagnet 411 is energized, causing the distance sleeve 42 to extend forward. At this time, the telescopic cylinder 31 starts to work, pushing the sliding frame 32 to move forward. The movement of the sliding frame 32 drives the spray gun head 41 to move towards the pot clamp 22. After the front end of the distance sleeve 42 touches the side of the pot 1, the spray gun head 41 stops moving forward. At this time, the telescopic cylinder 31 continues to move forward, causing the sliding frame 32 and the spray gun head 41 to move relative to each other. The sliding block 412 moves relative to the rear end of the sliding rheostat 431. When the telescopic cylinder 31 is fully extended, the brake pad 321 clamps and locks the spray gun head 41. At the same time, the first electromagnet 411 is de-energized, and the distance sleeve 42 retracts under the action of the first elastic element 422. At this time, the spray gun head 41 maintains a suitable spraying distance from the pot 1.

[0036] Multiple sets of spray gun heads 41 and inclined rails 52 are evenly arranged in the vertical direction of the sliding frame 32. Therefore, the spray gun head 41 at each vertical position will stop at different positions according to the curvature of the side wall of the pot body 1. The smaller the distance between the spray gun head 41 and the rotating shaft 221, the smaller the flow section of the hose 522 connected to the spray gun head 41. As a result, the flow rate of the spray gun head 41 at the position with a larger diameter of the pot body 1 is greater than that of the spray gun head 41 at the position with a smaller diameter. This ensures that the paint sprayed on the side of the pot body 1 at the same rotation speed is basically consistent on both the large and small diameters.

[0037] The rim of the ordinary pot body 1 is the largest diameter position. Therefore, a sliding rheostat 431 is set on the side of the bottom spray gun head 41 so that the bottom end contacts the largest diameter of the pot body 1. The stop position of the spray gun head 41 is different depending on the diameter of the pot body 1. The larger the diameter of the pot body 1, the earlier the spray gun head 41 stops moving forward, that is, the greater the sliding distance of the sliding block 412. This results in a greater resistance connected to the rotating motor 23. Thus, the rotation speed of the rotating motor 23 can be automatically adjusted according to the different sizes of the pot body 1 entering the spraying station. The larger the diameter of the pot body 1, the slower the rotation speed during spraying, thereby improving the uniformity of the spraying on the surface of the pot body.

[0038] After the rotating motor 23 has been rotating for a certain period of time, it stops rotating and the locking device is unlocked, allowing the pot body clamp 22 that has been sprayed to move forward under the action of the speed-multiplying chain 21. Since it is a batch spraying, the telescopic device 3 does not retract at this time, so the spray gun head 41 at each position does not move. The unsprayed pot body clamp 22 on the sliding track 21 automatically enters the spraying station, the locking device locks again, and the rotating motor 23 starts rotating again.

[0039] After a batch of spraying is completed, the telescopic device 3 retracts and everything returns to its initial position. When the next batch of pot 1 is sprayed, the telescopic device 3 extends again and automatically adjusts the rotation speed of the rotating motor 23 according to the size of the pot 1. At the same time, it automatically adjusts the flow rate of the spray gun head 41 at each spraying position according to the arc surface of the pot 1, so that the coating thickness of the finished product after spraying is basically consistent.
