Abstract

The present application relates to the technical field of pot manufacturing, and discloses a polishing device for iron pot casting and a polishing method thereof, which comprises a base, a shell fixedly installed on the top of the base, a power chamber fixedly installed on one side of the outer surface of the shell, a dustproof chamber fixedly installed on the other side of the outer surface of the shell, and a conveying device fixedly installed on the outer surface of the shell, near both ends and inside the power chamber.

Description

Technical Field

[0001] This invention relates to the field of cookware manufacturing technology, specifically to a grinding device and grinding method for casting iron pots and pans. Background Technology

[0002] Iron pots are a very common type of kitchen cooking utensil. During the production of iron pots, sandblasting machines are used to polish their surfaces, creating a rougher surface that allows for better adhesion of the coating during subsequent spraying, thus ensuring the pot is non-stick. Existing traditional sandblasting machines consist of sandblasting equipment, a casing, and a conveyor belt. During operation, the sandblasting equipment starts and sprays high-speed abrasive sand, while the conveyor belt moves the pot forward, thus polishing it. This type of polishing equipment has the advantages of simple structure, ease of use, and low cost, making it the most widely used polishing equipment currently available.

[0003] Although existing grinding equipment has many advantages, it still has certain limitations in actual use. Because the position of the cookware on the conveyor belt is uncertain, it cannot be aligned with the sandblasting nozzle. The sandblasting equipment cannot completely cover the cookware, resulting in insufficient grinding of the cookware surface, which affects the subsequent spraying operation. In this regard, this application proposes a grinding equipment for casting iron pots and cookware, which aims to solve the above-mentioned problems. Summary of the Invention

[0004] In view of the shortcomings of existing grinding equipment for casting iron pots and cookware mentioned in the background art, the present invention provides a grinding equipment for casting iron pots and cookware that has the advantage of better covering the abrasive with the grinding sand sprayed by the sandblasting equipment, thus solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a grinding device for casting iron pots and pans, comprising a base, a shell fixedly installed on the top of the base, a power chamber fixedly installed on one side of the outer surface of the shell, a dustproof chamber fixedly installed on the other side of the outer surface of the shell, a transport device fixedly installed on one side of the outer surface of the shell near both ends and inside the power chamber, an acceleration device fixedly installed on one side of the outer surface of the shell inside the power chamber, one end of the output shaft of the acceleration device fixedly connected to the transport device, a partition plate fixedly installed on the top of the inner cavity of the shell, guide strips fixedly installed on both sides of the inner cavity of the shell and both sides of the partition plate, a telescopic machine fixedly installed on the top of the shell on both sides of the partition plate, the telescopic machines fixedly installed on the top of the shell in an array arrangement, and a sandblasting device fixedly installed on one end of the output shaft of the telescopic machine penetrating the shell.

[0006] Preferably, the transport device includes a rotating roller, with limit shafts fixedly installed at both ends of the rotating roller. The limit shafts are movably connected to the outer shell through bearings. The outer surface of the rotating roller is provided with trapezoidal grooves, which are arranged in an array along the axial direction of the rotating roller. A transport belt is movably connected to the outer surface of the rotating roller through the trapezoidal grooves.

[0007] Preferably, there are gaps between the conveyor belts, and these gaps correspond to the acceleration device.

[0008] Preferably, the acceleration device includes four mounting shafts. Both ends of the mounting shafts are movably connected to the housing via bearings. A transmission disc is fixedly mounted on one end of each mounting shaft. The transmission discs are connected to each other via a transmission belt. A drive motor is fixedly mounted on one end of each mounting shaft. One end of the output shaft of the drive motor is fixedly connected to the transmission disc. A sensing device is fixedly mounted on the outer surface of the mounting shaft.

[0009] Preferably, the sensing devices are arranged in an array along the axial direction of the mounting shaft, and the positions of the sensing devices correspond to the gaps between the conveyor belts.

[0010] Preferably, the sensing device includes a rotating base, and four telescopic sleeves are fixedly installed on the outer surface of the rotating base. The telescopic sleeves are arranged in a circular array. A telescopic rod is movably sleeved inside the telescopic sleeve. A rubber head is fixedly installed at one end of the telescopic rod. A return spring is fixedly installed at the bottom of the rubber head on the outside of the telescopic rod. A pressure sensor is fixedly installed at the top of the telescopic rod. The bottom of the return spring is fixedly connected to the pressure sensor. Synchronous rotating shafts are fixedly installed at both ends of the rotating base. Contact rods are fixedly installed on the outer surface of the synchronous rotating shafts.

[0011] Preferably, the positions of the synchronous rotating shaft and the contact rod correspond to those of the conveyor belt.

[0012] Preferably, the output shaft of the pressure sensor is connected to the input end of the telescopic machine via a signal connection.

[0013] Preferably, the total height of the telescopic sleeve, telescopic rod, and rubber head is greater than the distance between the rotating seat and the conveyor belt.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention uses a fixed connection between the bottom of a return spring and a pressure sensor. When the top of the rubber head contacts the cookware above the conveyor device, the return spring contracts under the weight of the cookware. At this time, the distance between the rubber head and the rotating seat decreases. The total height of the telescopic sleeve, telescopic rod, and rubber head is greater than the distance between the rotating seat and the conveyor belt. Therefore, when the cookware is lightweight, the return spring retracts less, and the distance between the rubber head and the rotating seat is larger, resulting in a higher linear velocity of the rubber head. This allows the lighter cookware to be lifted and moved at a higher speed, avoiding... This invention addresses the problem of excessively long polishing time for smaller or lighter cookware, leading to excessive surface roughness and affecting the quality of subsequent anti-stick coating application. When the cookware is heavier, the return spring has a higher degree of retraction, resulting in a smaller distance between the rubber head and the rotating base. This lowers the linear velocity of the rubber head, lifting the heavier cookware and moving it at a lower speed. This avoids the problem of insufficient polishing time for larger or harder cookware, which would result in insufficient surface roughness and prevent the anti-stick coating from adhering properly. This improves the practicality of the device.

[0016] 2. This invention aligns the positions of the synchronous rotating shaft and the contact rod with the conveyor belt. As the synchronous rotating shaft rotates together with the rotating seat, the contact rod continuously contacts and impacts the conveyor belt, causing the conveyor belt to oscillate up and down. This allows the abrasive sand falling above the conveyor belt to fall through the gaps between the belts under the oscillation, avoiding the problem of abrasive sand falling onto the outside of the equipment and causing waste due to the rotation of the conveyor belt, thus reducing the operating cost of the device.

[0017] 3. This invention connects the output shaft of the pressure sensor to the input end of the telescopic conveyor via a signal connection. This means that when a small pot passes through the device, the number of sensors in contact with it is small, resulting in a smaller total pressure sensed by the pressure sensors connected to the telescopic conveyor and fewer pressure sensors generating pressure signals. At this time, the telescopic conveyor controls the sandblasting equipment to move vertically downwards, reducing the distance between the sandblasting end and the pot. This avoids the problem of some sandblasting material not contacting the pot body due to the greater distance of the blasting nozzles when the pot is small, thus preventing waste. When a larger pot passes through the device, the number of sensors in contact with it is greater. This results in a larger total pressure sensed by the pressure sensors connected to the telescopic conveyor, and a greater number of pressure sensors generating pressure signals. At this time, the telescopic conveyor controls the sandblasting equipment to move vertically upward, increasing the distance between the sandblasting end and the pot. This avoids the problem of the sandblasting nozzles being too close together, preventing the outer surface of the pot from contacting the abrasive sand when the pot is large. This improves the stability of the device during operation. At the same time, when the sensing device is not in contact with the pot, the pressure sensed by the pressure sensor is zero. At this time, the pressure sensor controls the sandblasting equipment to stop sandblasting, avoiding the problem of the abrasive sand not contacting the pot and thus being wasted, reducing the operating cost of the device.

[0018] 4. The present invention has guide strips fixedly installed on both sides of the inner cavity of the outer shell and both sides of the partition plate. When the cookware enters the inner shell, the guide strips can push the cookware to the middle position of the transport device, thereby ensuring that the nozzle at the bottom of the sandblasting equipment can be aligned with the cookware. This avoids the problem that the cookware's position may be offset, which would prevent the device from fully sanding it, and further improves the stability of the device.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-4A grinding device for casting iron pots and cookware includes a base 1, a housing 2 fixedly mounted on the top of the base 1, a power chamber 3 fixedly mounted on one side of the outer surface of the housing 2, a dustproof chamber 4 fixedly mounted on the other side of the outer surface of the housing 2, a transport device 5 fixedly mounted on one side of the outer surface of the housing 2 near both ends and inside the power chamber 3, an acceleration device 6 fixedly mounted on one side of the outer surface of the housing 2 inside the power chamber 3, one end of the output shaft of the acceleration device 6 fixedly connected to the transport device 5, a partition plate 7 fixedly mounted on the top of the inner cavity of the housing 2, and fixed on both sides of the inner cavity of the housing 2 and both sides of the partition plate 7. Guide bars 8 are installed to ensure that when the cookware enters the interior of the outer shell 2, the guide bars 8 can push the cookware to the middle position of the transport device 5, thereby ensuring that the nozzle at the bottom of the sandblasting equipment 10 can be aligned with the cookware, avoiding the problem that the position of the cookware will be offset and the device will not be able to grind it sufficiently, and further improving the stability of the device. Telescopic machines 9 are fixedly installed on the top of the outer shell 2 on both sides of the partition plate 7. The telescopic machines 9 are fixedly installed on the top of the outer shell 2 in an array arrangement. The output shaft of the telescopic machine 9 passes through the outer shell 2, and the sandblasting equipment 10 is fixedly installed at one end of the output shaft of the telescopic machine 9.

[0032] Please see Figure 5 The transport device 5 includes a rotating roller 51. Limiting shafts 52 are fixedly installed at both ends of the rotating roller 51. The limiting shafts 52 are movably connected to the outer shell 2 through bearings. Trapezoidal grooves 53 are opened on the outer surface of the rotating roller 51. The trapezoidal grooves 53 are arrayed along the axial direction of the rotating roller 51. A transport belt 54 is movably connected to the outer surface of the rotating roller 51 through the trapezoidal grooves 53.

[0033] Please see Figure 5 There are gaps between the conveyor belts 54, and these gaps correspond to the acceleration device 6.

[0034] Please see Figures 6-7 The acceleration device 6 includes four mounting shafts 61. Both ends of the mounting shafts 61 are movably connected to the housing 2 via bearings. A transmission disc 62 is fixedly mounted on one end of each mounting shaft 61. The transmission discs 62 are connected to each other via a transmission belt. A drive motor 63 is fixedly mounted on one end of the mounting shaft 61. One end of the output shaft of the drive motor 63 is fixedly connected to the transmission disc 62. A sensing device 64 is fixedly mounted on the outer surface of the mounting shaft 61.

[0035] Please see Figures 6-7 The sensing devices 64 are arranged in an array along the axial direction of the mounting shaft 61, and the positions of the sensing devices 64 correspond to the gaps between the conveyor belts 54.

[0036] Please see Figures 8-10The sensing device 64 includes a rotating base 641. A telescopic sleeve 642 is fixedly installed on the outer surface of the rotating base 641. There are four telescopic sleeves 642 arranged in a circular array. A telescopic rod 643 is movably sleeved inside the telescopic sleeve 642. A rubber head 644 is fixedly installed at one end of the telescopic rod 643. A return spring 645 is fixedly installed at the bottom of the rubber head 644, located outside the telescopic rod 643. A pressure sensor 646 is fixedly installed at the top of the telescopic rod 643. The bottom of the return spring 645 is fixedly connected to the pressure sensor 646. When the top of the rubber head 644 contacts the pot above the transport device 5, the return spring 645 contracts under the weight of the pot. At this time, the distance between the rubber head 644 and the rotating base 641 decreases. Synchronous rotating shafts 647 are fixedly installed at both ends of the rotating base 641. A contact rod 648 is fixedly installed on the outer surface of the synchronous rotating shaft 647.

[0037] Please see Figures 8-10 The positions of the synchronous rotating shaft 647 and the contact rod 648 correspond to the conveyor belt 54. As the synchronous rotating shaft 647 rotates together with the rotating seat 641, the contact rod 648 will continuously contact and impact the conveyor belt 54, causing the conveyor belt 54 to continuously swing up and down. This allows the abrasive sand falling on the conveyor belt 54 to fall through the gaps between the conveyor belts under the action of swinging, avoiding the problem of abrasive sand falling to the outside of the equipment and causing waste during the rotation of the conveyor belt 54, and reducing the operating cost of the device.

[0038] Please see Figures 8-10The output shaft of pressure sensor 646 is connected to the input end of telescopic conveyor 9 via a signal connection. This means that when a small pot passes through the device, the number of sensors 64 in contact with it is small, resulting in a smaller total pressure sensed by the pressure sensors 646 connected to the telescopic conveyor 9 and fewer pressure sensors 646 generating pressure signals. At this time, the telescopic conveyor 9 controls the sandblasting equipment 10 to move vertically downwards, reducing the distance between the sandblasting end of the equipment and the pot. This avoids the problem of some abrasive sand not contacting the pot body due to the greater distance of the blasting nozzles when the pot is small, thus preventing waste. When a larger pot passes through the device, the number of sensors 64 in contact with it is larger, thus... The pressure sensors 646 connected to the telescopic conveyor 9 sense a large total pressure and generate a large number of pressure sensors 646. At this time, the telescopic conveyor 9 controls the sandblasting equipment 10 to move vertically upward, increasing the distance between the sandblasting end of the sandblasting equipment 10 and the pot. This avoids the problem that when the pot has a large volume, the sandblasting nozzles are too close together, causing the outer part of the pot surface to not be able to contact the abrasive. This improves the stability of the device during operation. At the same time, when the sensing device 64 is not in contact with the pot, the pressure sensed by the pressure sensor 646 is zero. At this time, the pressure sensor 646 controls the sandblasting equipment 10 to stop sandblasting, avoiding the problem of the sprayed abrasive not being able to contact the pot and thus being wasted. This reduces the operating cost of the device.

[0039] Please see Figures 8-10 The total height of the telescopic sleeve 642, telescopic rod 643, and rubber head 644 is greater than the distance between the rotating seat 641 and the conveyor belt 54. This means that when the cookware is lightweight, the return spring 645 has a lower degree of retraction, and the distance between the rubber head 644 and the rotating seat 641 is larger, resulting in a higher linear velocity of the rubber head 644. This allows the lighter cookware to be lifted and moved at a higher speed, avoiding the problem of excessive grinding time for small or lightweight cookware, which could lead to excessive surface roughness and affect the subsequent anti-stick coating spraying quality. Conversely, when the cookware is heavy, the return spring 645 has a higher degree of retraction, and the distance between the rubber head 644 and the rotating seat 641 is smaller, resulting in a lower linear velocity of the rubber head 644. This allows the heavier cookware to be lifted and moved at a lower speed, avoiding the problem of insufficient grinding time for large or hard cookware, which could lead to insufficient surface roughness and prevent the subsequent anti-stick coating from adhering properly. This improves the practicality of the device.

[0040] The method of using this invention is as follows:

[0041] During use, when the cookware is light, the return spring 645 retracts less, resulting in a larger distance between the rubber head 644 and the rotating seat 641. This causes the linear velocity of the rubber head 644 to be higher, lifting the lighter cookware and moving it at a higher speed. Conversely, when the cookware is heavy, the return spring 645 retracts more, resulting in a smaller distance between the rubber head 644 and the rotating seat 641. This causes the linear velocity of the rubber head 644 to be lower, lifting the heavier cookware and moving it at a lower speed. As the synchronous rotating shaft 647 rotates together with the rotating seat 641, the contact rod 648 continuously contacts and impacts the conveyor belt 54, causing the conveyor belt 54 to oscillate up and down. This allows the abrasive sand falling on the conveyor belt 54 to fall through the gaps between the belts under the oscillation. When a small cookware passes through the inside of the device, the number of contacts between the sensing device 64 and the device is small, thus activating the pressure sensor connected to the telescopic mechanism 9. When the total pressure sensed by pressure sensor 646 is relatively small and the number of pressure sensors 646 generating pressure signals is small, the telescopic machine 9 controls the sandblasting equipment 10 to move vertically downward, reducing the distance between the sandblasting end of the sandblasting equipment 10 and the pot. When a larger pot passes through the interior of the device, due to the large number of sensors 64 in contact with it, the total pressure sensed by pressure sensors 646 connected to the telescopic machine 9 is large, and the number of pressure sensors 646 generating pressure signals is large. At this time, the telescopic machine 9 controls the sandblasting equipment 10 to move vertically upward, increasing the distance between the sandblasting end of the sandblasting equipment 10 and the pot. When the sensors 64 do not contact the pot, the pressure sensed by pressure sensor 646 is zero. At this time, pressure sensor 646 controls the sandblasting equipment 10 to stop sandblasting. When the pot enters the interior of the outer shell 2, the guide bar 8 can push the pot to the middle position of the transport device 5, thereby ensuring that the nozzle at the bottom of the sandblasting equipment 10 can be aligned with the pot.
