Description

Technical Field

[0001] This invention relates to the field of hot pot manufacturing equipment technology, and in particular to a hot pot welding device and its usage method. Background Technology

[0002] An existing type of hot pot has the following structure: Figure 14 As shown, the hot pot 1 includes a pot body 1-1 and a partition 1-2 disposed inside the pot body. The partition 1-2 is S-shaped and divides the interior of the pot body 1-1 into two independent cooking spaces, which can realize the simultaneous cooking of two different flavored soup bases.

[0003] In the existing hot pot manufacturing process, a partition 1-2 needs to be placed inside the pot body, and then welded to the connection between the partition 1-2 and the pot body 1-1 to fix the partition 1-2 and the pot body 1-1 together. However, the following problems exist in actual welding: local heating and cooling during the welding process can cause uneven expansion and contraction of the materials of the partition 1-2 and the pot body 1-1, which can easily lead to serious deformation of the entire pot body 1-1 or the partition 1-2, seriously affecting the quality of the hot pot. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a hot pot welding device and its usage method.

[0005] The objective of this invention is achieved through the following technical solution: a hot pot welding device, comprising a welding apparatus and a positioning base plate for placing the pot body; a side clamping device for fixing the pot body is provided on the positioning base plate; a contour clamping component that can move up and down is provided above the positioning base plate; during the welding process, the contour clamping component clamps the partition and supports the inner side of the pot body.

[0006] Preferably, the contour clamping component is mounted on the lifting device, which includes a guide frame, a lifting plate slidably connected to the guide frame, the contour clamping component being fixedly connected to the lifting plate, and a lifting driver being provided at the upper end of the guide frame, the lifting driver being connected to the lifting plate.

[0007] Preferably, the contouring clamping component includes a contouring inner support block and a clamping plate. A clamping driver is provided between the contouring inner support block and the clamping plate. A third contouring surface adapted to the partition is provided on one side of the clamping plate. The contouring inner support block is provided with a first contouring surface adapted to the shape of the partition and a second contouring surface adapted to the inner wall of the pot. When the contouring clamping component clamps the partition, the partition is clamped between the first contouring surface and the second contouring surface.

[0008] Preferably, the contoured inner support block is provided with a first guide groove, and a first top block is slidably disposed in the first guide groove. The first top block moves between an extended state and a retracted state. The contoured inner support block is provided with a first driving mechanism, which includes a mounting cavity disposed on the contoured inner support block. The mounting cavity is located at one end of the first guide groove, and a first driving member is disposed in the mounting cavity. The first driving member includes a main body, and a first protrusion is provided on one side of the main body. A first groove is provided at the end of the first top block near the first driving member. The first driving member is connected to a first ejector driver and is driven to move upward by the first ejector driver. When the first protrusion is embedded in the first groove, the first top block is in a retracted state, at which time the first top block is not higher than the first contoured surface. When the first protrusion is disengaged from the first groove, the first top block... In the ejected state, one end of the first top block is higher than the first contouring surface; a second guide groove is provided on the clamping plate, and a second top block is slidably disposed in the second guide groove. The second top block moves between the extended state and the retracted state. A second driving mechanism is provided on the contouring inner support block; the second driving mechanism includes a second driving member disposed at one end of the second top block, and a second protrusion is provided on the second driving member. A second groove is provided at the end of the second top block near the second driving member; the second driving member is connected to a second ejection driver and is driven to move up and down by the second ejection driver; when the second protrusion is embedded in the second groove, the second top block is in the retracted state, and at this time the second top block is not higher than the third contouring surface; when the second protrusion is disengaged from the second groove, the second top block is in the ejected state, and at this time the second top block is higher than the third contouring surface.

[0009] Preferably, when the contour clamping component is in the initial clamping state, the first top block on the contour inner support block and the second top block on the clamping plate are both in the ejected state, and the first top block and the second top block are respectively pressed against the two sides of the partition. The first top block and the second top block are alternately pressed to increase the bending degree of the partition. When the contour clamping component is in the final clamping state, the first top block on the contour inner support block and the second top block on the clamping plate are both in the retracted state, and the two sides of the partition are respectively in contact with the first contour surface and the third contour surface.

[0010] Preferably, the contoured inner support block is provided with a limiting plate for limiting the position of the partition, and the clamping plate is provided with an avoidance groove corresponding to the limiting plate.

[0011] Preferably, the positioning base plate is disposed on the base plate, the base plate is provided with a guide rail, and the positioning base plate is slidably connected to the guide rail; a lead screw is rotatably disposed on the base plate, the lead screw is parallel to the guide rail, a lead screw nut is disposed on the positioning base plate, and the lead screw and the lead screw nut are threadedly engaged; an adjustment handle is provided at one end of the lead screw.

[0012] Preferably, the positioning base plate is provided with a positioning groove; the side clamping device is provided on both sides of the positioning groove, and the side clamping device includes a first cylinder and a clamping block connected to the first cylinder.

[0013] A method of using a hot pot welding equipment includes the following steps: S1, placing the pot body on the positioning base plate and clamping the pot body using the side clamping device;

[0014] S2. The partition is clamped between the clamping plate and the contouring inner support block. The contouring clamping component is switched to the initial clamping state. The first top block on the contouring inner support block and the second top block on the clamping plate are both in the extended state. The first top block and the second top block press against the two sides of the partition respectively. Then the contouring clamping component moves downward and sends the partition into the welding position inside the pot.

[0015] S3. The contour clamping component switches to the final clamping state, so that the two sides of the partition plate are respectively attached to the first contour surface and the third contour surface, and the two ends of the partition plate are in contact with the inner wall of the pot.

[0016] S4. Weld the connection between the partition and the pot body using a welding device.

[0017] The beneficial effects of this invention are:

[0018] 1. During the welding process, the present invention uses the clamping and fixing action of the contour clamping component to stably position the partition in the preset position of the pot body, ensuring a uniform welding gap at the connection between the partition and the pot body. This avoids uneven heat distribution caused by fluctuating gap size, fundamentally reducing problems such as partition bending and displacement caused by uneven welding stress. Furthermore, the contour clamping component acts as an internal support for the pot body. During the welding process, the contour clamping component is placed inside the pot body, and its contour structure design allows it to completely conform to the contour of the inner wall of the pot and the partition during the welding process. The tendency of the pot body to "shrink inward" or "protrude locally" due to uneven thermal expansion and contraction during welding is offset by the supporting force of the contour clamping component, thereby suppressing the deformation of the pot body and the partition and reducing the degree of product deformation.

[0019] 2. In the initial clamping state, both the first and second top blocks of the contour clamping component are in an extended position, and they alternately press against both sides of the partition. The localized pressure exerted by the first and second top blocks on specific points on the partition forces it to undergo further controllable and uniform bending deformation, thereby increasing the degree of bending and reducing the maximum lateral width of the partition. This allows the bent partition to easily pass through the pot opening and be inserted into the welding position inside the pot, completely avoiding friction and interference between the two ends and the inner wall of the pot, thus thoroughly solving the problem of partition installation. The difficult problem is that after the contour clamping component descends to its position, it switches to the final clamping state. The partition is clamped by the third contour surface on the clamping plate and the first contour surface on the contour inner support block. The two sides of the partition are completely in contact with the first contour surface of the contour inner support block and the third contour surface of the clamping plate. The distance between the two ends of the partition is extended, and the distance between the two ends of the partition is restored to the design width and consistent with the internal width of the pot body. The two ends of the partition will press against the inner wall of the pot body, greatly reducing the gap between the two ends of the partition and the pot body, thus ensuring the welding quality of the two ends of the partition.

Detailed Implementation

[0035] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0036] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0037] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0038] like Figures 1 to 13 As shown, a hot pot welding device includes a welding device 3 and a positioning base plate 4 for placing the pot body 1-1; a side clamping device 6 for fixing the pot body 1-1 is provided on the positioning base plate 4; a contour clamping component 10 that can move up and down is provided above the positioning base plate 4; during the welding process, the contour clamping component 10 clamps the partition 1-2 and supports the inner side of the pot body 1-1.

[0039] The welding device 3 and the positioning base plate 4 are both mounted on the frame 2. During welding, the pot body 1-1 is placed on the positioning base plate 4 and fixed in place by the side clamping device 6.

[0040] The vertically movable contour clamping component 10 can accurately clamp the partition 1-2 and send it into the designated welding position inside the pot body 1-1. During the welding process, the clamping and fixing effect of the contour clamping component 10 on the partition 1-2 ensures that the "S"-shaped partition 1-2 is stably positioned in the preset position of the pot body 1-1, ensuring that the welding gap at the connection between the partition 1-2 and the pot body 1-1 is uniform, avoiding uneven distribution of welding heat caused by sudden changes in the gap, and fundamentally reducing problems such as bending and displacement of the partition 1-2 caused by uneven welding stress. Secondly, the contour clamping component 10 provides internal support for the pot body 1-1. During the welding process, the contour clamping component 10 is placed inside the pot body 1-1. Its contour structure design allows it to completely conform to the inner wall contour of the pot body 1-1 and the partition 1-2 during the welding process. The tendency of the pot body 1-1 to "shrink inward" or "protrude locally" due to uneven thermal expansion and contraction during welding will be offset by the supporting force of the contour clamping component 10. This is equivalent to adding a "rigid support skeleton" inside the pot body 1-1, thereby suppressing the deformation of the pot body 1-1 and the partition 1-2 and reducing the degree of product deformation.

[0041] The welding positions of the partition plate 1-2 and the pot body 1-1 are always precisely aligned through the coordinated positioning of the side clamping device 6 and the contour clamping component 10, avoiding problems such as incomplete welding, missing welding or welding deviation caused by component displacement, and ensuring the welding quality of the connection.

[0042] The contour clamping component 10 is installed on the lifting device, which includes a guide frame 7, a lifting plate 8 is slidably connected to the guide frame 7, the contour clamping component 10 is fixedly connected to the lifting plate 8, and a lifting driver 9 is provided at the upper end of the guide frame 7, which is connected to the lifting plate 8.

[0043] The lifting plate 8 and the guide frame 7 are slidably engaged, allowing the lifting plate 8 to move up and down under the guidance of the guide frame 7. The lifting driver 9 serves as the power source for lifting and is used to drive the contour clamping component 10 to move up and down. Before welding, the partition 1-2 is first clamped by the contour clamping component 10. Then, the lifting driver 9 drives the contour clamping component 10 and the partition 1-2 to move downward together so that the partition 1-2 enters the designated welding position within the pot body 1-1. The continuous clamping action of the contour clamping component 10 keeps the partition 1-2 stable during the welding process, improving the welding quality.

[0044] In this embodiment, the lifting driver 9 is a cylinder.

[0045] The contour clamping component 10 includes a contour inner support block 10-1 and a clamping plate 10-2. A clamping driver 10-3 is provided between the contour inner support block 10-1 and the clamping plate 10-2. A third contour surface 10-2a adapted to the partition 1-2 is provided on one side of the clamping plate 10-2. The contour inner support block 10-1 is provided with a first contour surface 10-1a adapted to the shape of the partition 1-2 and a second contour surface 10-1b adapted to the inner sidewall of the pot body 1-1. When the contour clamping component 10 clamps the partition 1-2, the partition 1-2 is clamped between the first contour surface 10-1a and the third contour surface 10-2a.

[0046] The first contouring surface 10-1a and the third contouring surface 10-2a are both adapted to the surfaces on both sides of the partition 1-2, and are both "S"-shaped curved surface structures. The first contouring surface 10-1a and the third contouring surface 10-2a are located on the contouring inner support block 10-1 and the clamping plate 10-2, respectively. When the clamping driver 10-3 drives the clamping plate 10-2 to move closer to the contouring inner support block 10-1, the two contouring surfaces will approach from both sides of the partition 1-2 and clamp the partition 1-2, which can effectively prevent the partition 1-2 from shifting during clamping, and ultimately ensure that the partition 1-2 is fixed in the preset welding position with the pot body 1-1, completely eliminating problems such as weld misalignment and uneven welding gap caused by inaccurate positioning of the partition 1-2. During welding, the second contouring surface 10-1b will fit against the inner wall of the pot body 1-1, thereby providing internal support for the pot body 1-1 and suppressing the deformation of the pot body 1-1.

[0047] Furthermore, the contour clamping component 10 can also correct the shape of the partition 1-2 during the clamping process. Since the partition 1-2 is typically made of stainless steel and is a thin-walled component, it is easily subjected to uncontrollable bending deformation under external forces during transportation and storage, causing its shape to deviate from the design shape. In this invention, during the welding process, the partition 1-2 is firmly clamped between the first contour surface 10-1a and the third contour surface 10-2a. The compression action of the contour surfaces corrects the bent and deformed partition 1-2, allowing it to return to its design shape during welding.

[0048] In this embodiment, the clamping actuator 10-3 is a cylinder. The cylinder body of the clamping actuator 10-3 is fixed on the contoured inner support block 10-1, and the telescopic rod of the clamping actuator 10-3 is connected to the clamping plate 10-2. The clamping actuator 10-3 drives the clamping plate 10-2 to move horizontally.

[0049] Furthermore, a first guide groove 10-1d is provided on the contoured inner support block 10-1, and a first top block 10-6 is slidably disposed in the first guide groove 10-1d. The first top block 10-6 moves between an extended state and a retracted state. A first driving mechanism is provided on the contoured inner support block 10-1. The first driving mechanism includes a mounting cavity 10-1c disposed on the contoured inner support block 10-1. The mounting cavity 10-1c is located at one end of the first guide groove 10-1d. A first driving member 10-5 is disposed in the mounting cavity 10-1c. The first driving member 10-5 includes a main body portion 10-5a. A first protrusion 10-5b is provided on one side of the first top block 10-6, and a first groove 10-6a is provided at one end of the first top block 10-6 near the first driving member 10-5. The first driving member 10-5 is connected to the first ejector driver 10-4 and is driven to move upward by the first ejector driver 10-4. When the first protrusion 10-5b is inserted into the first groove 10-6a, the first top block 10-6 is in a retracted state, at which time the first top block 10-6 is not higher than the first contour surface 10-1a. When the first protrusion 10-5b is disengaged from the first groove 10-6a, the first top block 10-6 is... In the ejected state, one end of the first top block 10-6 is higher than the first contouring surface 10-1a; the clamping plate 10-2 is provided with a second guide groove 10-2c, and a second top block 10-10 is slidably disposed in the second guide groove 10-2c. The second top block 10-10 moves between the extended state and the retracted state. The contouring inner support block 10-1 is provided with a second driving mechanism; the second driving mechanism includes a second driving member 10-9 disposed at one end of the second top block 10-10, and a second protrusion 10-9a is provided on the second driving member 10-9. The second top block 10-10 is close to the second driving member 10-10. -9 has a second groove 10-10a at one end; the second driving member 10-9 is connected to the second ejector driver 10-8 and drives the second driving member 10-9 to move up and down through the second ejector driver 10-8; when the second protrusion 10-9a is embedded in the second groove 10-10a, the second top block 10-10 is in a retracted state, at which time the second top block 10-10 is not higher than the third contour surface 10-2a; when the second protrusion 10-9a is disengaged from the second groove 10-10a, the second top block 10-10 is in an ejected state, at which time the second top block 10-10 is higher than the third contour surface 10-2a.

[0050] When the contour clamping component 10 is in the initial clamping state, the first top block 10-6 on the contour inner support block 10-1 and the second top block 10-10 on the clamping plate 10-2 are both in the ejected state. The first top block 10-6 and the second top block 10-10 are respectively pressed against the two sides of the partition plate 1-2. The first top block 10-6 and the second top block 10-10 are alternately pressed to increase the bending degree of the partition plate 1-2. When the contour clamping component 10 is in the final clamping state, the first top block 10-6 on the contour inner support block 10-1 and the second top block 10-10 on the clamping plate 10-2 are both in the retracted state. The two sides of the partition plate 1-2 are respectively in contact with the first contour surface 10-1a and the third contour surface 10-2a.

[0051] The cross-sections of the first protrusion 10-5b, the second protrusion 10-9a, the first groove 10-6a, and the second groove 10-10a are all semi-circular.

[0052] Since the partition 1-2 is designed to be consistent with the internal width of the pot body 1-1, when the partition 1-2 is fed into the pot body 1-1 by the contour clamping component 10, the width of the two ends of the partition 1-2 is just right with the inner diameter of the pot body 1-1. If the lateral clamping position of the partition 1-2 is slightly off, or if the lateral width of the partition 1-2 is slightly larger during processing, the two ends of the partition 1-2 can easily interfere with the pot body 1-1, making it difficult to insert into the pot body 1-1.

[0053] The contour-following clamping component 10 of the present invention effectively solves the above-mentioned problems. For example... Figure 13 As shown, when the contour clamping component 10 is in the initial clamping state, both the first top block 10-6 (contour inner support block side) and the second top block 10-10 (clamping plate 10-2 side) are in the ejected state and are alternately clamped to both sides of the partition 1-2. Through the localized pressure exerted by the first top block 10-6 and the second top block 10-10 on specific points on the partition 1-2, the partition 1-2 (S-shaped thin-walled structure) is forced to undergo further controllable and uniform bending deformation, thereby increasing the degree of bending of the partition 1-2. When the degree of bending of the partition 1-2 increases, it will... The maximum lateral width of the partition 1-2 is reduced to be smaller than the internal width of the pot body 1-1. This ensures that when the partition 1-2 is inserted into the pot body 1-1, there is sufficient space between the two ends of the partition 1-2 and the inner wall of the pot body 1-1, preventing interference between the two ends of the partition 1-2 and the pot body 1-1. This allows the bent partition 1-2 to easily pass through the opening of the pot body 1-1 and be inserted into the welding position inside the pot body 1-1, completely avoiding scraping and interference between the two ends and the inner wall of the pot body 1-1, and thoroughly solving the problem of difficulty in installing the partition 1-2.

[0054] After the contour clamping component 10 descends to its final position, it switches to the final clamping state. During this switch, the first ejector driver 10-4 and the second ejector driver 10-8 actuate, causing the first protrusion 10-5b of the first driver 10-5 to move to a position directly opposite the first groove 10-6a, and causing the second protrusion 10-9a of the second driver 10-9 to move to a position directly opposite the second groove 10-10a. Then, the clamping driver 10-3 drives the clamping plate 10-2 to further engage. The partition 1-2 loses the clamping force of the first top block 10-6 and the second top block 10-10. The partition 1-2 is clamped by the third contouring surface 10-2a on the clamping plate 10-2 and the first contouring surface 10-1a on the contouring inner support block. The two sides of the partition 1-2 are completely in contact with the first contouring surface 10-1a of the contouring inner support block and the third contouring surface 10-2a of the clamping plate 10-2. The first top block 10-6 and the second top block 10-10 retract to the retracted state of "not higher than the contouring surface". During this process, the partition 1-2 recovers its designed shape under the clamping action of the first contour surface 10-1a and the second contour surface 10-1b, its bending degree is reduced, the distance between the two ends of the partition 1-2 is lengthened, the distance between the two ends of the partition 1-2 is restored to the designed width and is consistent with the internal width of the pot body 1-1, and the two ends of the partition 1-2 will press against the inner wall of the pot body 1-1, so that the gap between the two ends of the partition 1-2 and the pot body 1-1 is greatly reduced, ensuring the welding quality of the two ends of the partition 1-2.

[0055] The first driving member 10-5 has a connecting body 10-5c on its main body 10-5a, which connects it to the second ejector driver 10-8. One side of the main body 10-5a is in close contact with the side wall of the mounting cavity 10-1c, which guides the first driving member 10-5 to move vertically.

[0056] In this embodiment, both the first ejector driver 10-4 and the second ejector driver 10-8 are cylinders.

[0057] The contoured inner support block is provided with a limiting plate 10-7 for limiting the position of the partition 1-2, and the clamping plate 10-2 is provided with a relief groove 10-2b corresponding to the limiting plate 10-7. When the partition 1-2 is placed on the contoured clamping component 10, the upper end of the partition 1-2 contacts the limiting plate 10-7, and the limiting plate 10-7 limits the height of the partition 1-2.

[0058] The positioning base plate 4 is mounted on the base plate 5, and the base plate 5 is provided with a guide rail 11. The positioning base plate 4 is slidably connected to the guide rail 11. A lead screw 12 is rotatably mounted on the base plate 5. The lead screw 12 is parallel to the guide rail 11. A lead screw nut 13 is provided on the positioning base plate 4. The lead screw 12 and the lead screw nut 13 are threaded together. An adjustment handle is provided at one end of the lead screw 12.

[0059] The lead screw 12 is threadedly engaged with the lead screw nut 13 on the positioning base plate 4, and the lead screw 12 is parallel to the guide rail 11. When the adjustment handle is rotated, the lead screw 12 drives the lead screw nut 13 and the positioning base plate 4 to move linearly along the guide rail 11, thereby adjusting the position of the positioning base plate 4. By adjusting the position of the positioning base plate 4, this device can be adapted to pots of different sizes 1-1: for pots 1-1 with larger diameters, the lead screw 12 can be rotated by adjusting the handle to move the positioning base plate 4 away from the contour clamping component 10, expanding the placement space of the pot 1-1; for pots 1-1 with smaller diameters, the positioning base plate 4 can be adjusted in the opposite direction to bring it closer to the contour component; thus improving the versatility and applicable scenarios of the device.

[0060] The positioning base plate 4 is provided with a positioning groove 4-1; the side clamping device 6 is provided on both sides of the positioning groove 4-1, and the side clamping device 6 includes a first cylinder and a clamping block connected to the first cylinder. When fixing the pot body 1-1, the clamping block is driven to extend by the side clamping device 6 to tighten the pot body 1-1.

[0061] A method for using a hot pot welding device includes the following steps:

[0062] S1. Place the pot body 1-1 onto the positioning base plate 4 and clamp the pot body 1-1 using the side clamping device 6.

[0063] S2. Clamp the partition 1-2 between the clamping plate 10-2 and the contouring inner support block. Switch the contouring clamping component 10 to the initial clamping state. The first top block 10-6 on the contouring inner support block and the second top block 10-10 on the clamping plate 10-2 are both in the extended state. The first top block 10-6 and the second top block 10-10 press against the two sides of the partition 1-2 respectively. Then, the contouring clamping component 10 moves downward and sends the partition 1-2 into the welding position inside the pot body 1-1.

[0064] S3. The contour clamping component 10 switches to the final clamping state, so that the two sides of the partition 1-2 are respectively attached to the first contour surface 10-1a and the third contour surface 10-2a, and the two ends of the partition 1-2 are in contact with the inner wall of the pot body 1-1.

[0065] S4. Weld the connection between the partition plate 1-2 and the pot body 1-1 using the welding device 3.

However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
