Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a hot melt welding machine used for hot melt welding between an inner tank and a heating tube. Background Art

[0002] In the field of electrical appliance manufacturing, such as soymilk makers, the quality of the weld between the inner container and the heating element is directly related to the product's lifespan and safety. Traditionally, the heating element has been manually welded to the inner container. However, this production method often suffers from low welding efficiency and unstable welding quality, making it difficult to meet the needs of modern industrial production.

[0003] In order to solve this problem, the existing hot melt welding machine generally includes a lifting assembly, an upper hot pressing mold assembly and a lower hot pressing mold assembly, and the lifting assembly, the upper hot pressing mold assembly and the lower hot pressing mold assembly are used to form a hot melt welding station. However, the hot melt welding machine has only one or more side-by-side hot melt welding stations. Each hot melt welding station needs to complete the hot melt welding of the inner liner and the heating tube before it can proceed to the hot melt welding between the next inner liner and the heating tube. When the upper hot pressing mold assembly and the lower hot pressing mold assembly hot press the inner liner and the heating tube, it is necessary to wait for the hot pressing time, resulting in relatively low production efficiency, which is not conducive to the hot melt welding production between the inner liner and the heating tube.

DETAILED DESCRIPTION

[0033] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] like Figures 1 to 5 As shown, a hot melt welding machine for hot melt welding between an inner liner and a heating tube includes a workbench, a rotating motor 2, an I-shaped turret 3, a lower hot press die assembly 4, a lifting assembly 5, an upper hot press die assembly 6, and a safety clamping structure 7. The workbench 1 serves as the support platform for the entire welding machine, ensuring stable installation and operation of all components. The rotating motor 2 is mounted on the workbench 1; the I-shaped turret 3 is connected to the output shaft of the rotating motor 2 and rotates by the drive of the rotating motor 2; the rotating motor 2 provides power to the I-shaped turret 3, and by driving the output shaft of the rotating motor 2, the I-shaped turret 3 is rotated continuously or intermittently. The design of the I-shaped turret 3 allows the lower hot press die assembly 4, the lifting assembly 5, and the upper hot press die assembly to be evenly distributed, facilitating simultaneous operation of multiple welding stations. The lower hot press die assembly 4 is evenly arranged around the rotating motor 2 on the lower end of the I-shaped turret 3. The number of the lifting assemblies 5 is the same as the number of the lower hot pressing die assemblies 4 and they are arranged on the upper end of the I-shaped turret 3 in a one-to-one correspondence; preferably, the lifting assemblies 5 are air cylinders or hydraulic cylinders. The telescopic end of each lifting assembly 5 is connected to an upper hot pressing die assembly 6 that is hot-pressed with the lower hot pressing die assembly 4; the upper hot pressing die assembly 6 cooperates with the lower hot pressing die assembly 4 and is hot-pressed by the driving of the lifting assembly 5 to ensure a tight weld between the inner liner and the heating tube. The safety clamping structure 7 is used to clamp and take out the inner liner to ensure the stability of the inner liner during the welding process, while facilitating the operator to quickly take it out and improve production efficiency.

[0035] The hot melt welding machine for hot melt welding between the inner liner and the heating tube realizes the connection between the inner liner and the heating tube by arranging a workbench 1, a rotating motor 2, an I-shaped turret 3, a lower hot pressing die assembly 4, a lifting assembly 5, an upper hot pressing die assembly 6 and a safety clamping structure 7. The rotating motor 2 drives the I-shaped turret 3 to rotate, so that the lower hot pressing die assembly 4, the lifting assembly 5 and the upper hot pressing die assembly 6 rotate synchronously with the I-shaped turret 3. The lifting assembly 5 is used to adjust the position of the upper hot pressing die assembly 6, which is precisely matched with the lower hot pressing die assembly 4, ensuring that the inner liner and the heating tube are tightly welded by aluminum heat fusion welding. Under the rotation of the I-shaped turret 3, there is sufficient hot pressing fusion welding time, the connection between the inner liner and the heating tube is more stable, the welding quality is improved, and multiple welding stations can operate simultaneously, which significantly improves production efficiency.

[0036] In this embodiment, the I-shaped turret 3 comprises a lower turret plate 31, struts 32, and an upper turret plate 33. The lower turret plate 31 and the upper turret plate 33 are connected to each other via the upper and lower ends of the struts 32, respectively. The lower turret plate 31 serves as the foundation of the I-shaped turret 3, supporting the entire structure. The struts 32 connect the lower turret plate 31 and the upper turret plate 33, providing support and force transmission. The output shaft of the rotary motor 2 is connected to the struts 32. The lower hot press die assembly 4 is mounted on the lower turret plate 31, and the lifting assembly 5 is mounted on the upper turret plate 33. The rotary motor 2 drives the struts 32 to rotate, which in turn drives the upper turret plate 33 and the lower turret plate 31 to rotate together, thereby driving the lower hot press die assembly 4, the lifting assembly 5, and the upper hot press die assembly 6 to rotate together. This facilitates the switching of multiple welding stations. This not only ensures sufficient hot press welding time, ensuring a more stable connection between the liner and the heating tube, and improving welding quality, but also allows multiple welding stations to operate simultaneously, significantly increasing production efficiency.

[0037] In this embodiment, the lower hot pressing die assembly 4 includes an inner liner sleeve 41, a first heat shield 42, a first heating plate 43, and a first heat conducting plate 44. The lower end of the inner liner sleeve 41 is connected to the lower end of the I-shaped turret 3, providing support for the inner liner, which is inverted on the first heat conducting plate 44. The upper end of the inner liner sleeve 41 is connected to the first heat shield 42, the first heating plate 43, and the first heat conducting plate 44 in sequence from bottom to top. During this process, the first heat shield 42 functions to prevent heat loss and ensure effective heating. The lower hot pressing die assembly 4 is formed by the inner liner sleeve 41, the first heat shield 42, the first heating plate 43, and the first heat conducting plate 44. Heat is generated by the first heating plate 43, and then transferred to the inner liner via the first heat conducting plate 44, bringing the inner liner to the required temperature for hot pressing. This facilitates heating the aluminum heat welding plate between the inner liner and the heating tube to form a hot melt state, facilitating the hot melt welding between the inner liner and the heating tube.

[0038] The upper hot pressing mold assembly 6 includes a second heat insulation plate 61, an elastic shock absorber 62, a second heating plate 63 and a second heat conducting plate 64; the second heat insulation plate 61 is connected to the telescopic end of the lifting assembly 5;. This design of the second heat insulation plate 61 is to ensure that during the hot pressing process, heat can be effectively transferred to the material to be processed, while avoiding excessive heat diffusion to other parts that do not need to be heated, so as to maintain the accuracy and efficiency of the hot pressing process. The second heat insulation plate 61 is connected to the second heating plate 63 through the elastic shock absorber 62; the elastic shock absorber 62 is connected between the second heat insulation plate 61 and the second heating plate 63. Its main function is to reduce the vibration that may be generated during the hot pressing process, protect the equipment from damage, and improve the quality of hot pressing. The second heat conducting plate 64 is connected to the bottom end surface of the second heating plate 63. An upper hot pressing mold assembly 6 is formed by arranging a second heat insulation plate 61, an elastic shock-absorbing member 62, a second heating plate 63 and a second heat conducting plate 64. The second heating plate 63 is used to generate heat, and then the heat is transferred to the heating tube and the inner tank through the second heat conducting plate 64. Combined with the lower hot pressing mold assembly 4, it is convenient to heat the aluminum hot melt welding plate between the inner tank and the heating tube to form a hot melt state, which is conducive to achieving hot melt welding between the inner tank and the heating tube.

[0039] To better reduce vibrations that may occur during the hot pressing process, protect the equipment from damage, and improve the quality of the hot pressing, a plurality of elastic shock absorbers 62 are evenly distributed between the second heat insulation plate 61 and the second heating plate 63. Specifically, the elastic shock absorbers 62 include connecting posts 621 connected between the second heat insulation plate 61 and the second heating plate 63, and springs 622 mounted on the connecting posts 621.

[0040] In this embodiment, the safety clamping structure 7 includes a first clamp 71, a second clamp 72, a first hand-held rod 73, a second hand-held rod 74, a first material stop edge 75 and a second material stop edge 76; the front end of the first clamp 71 and the front end of the second clamp 72 are hinged and can be opened or closed relative to the left and right directions of the workbench 1; the first hand-held rod 73 and the second hand-held rod 74 are respectively connected to the rear end of the first clamp 71 and the rear end of the second clamp 72; the first material stop edge 75 and the second material stop edge 76 are respectively connected to the top of the first clamp 71 and the second clamp 72. By designing the first stop edge 75 and the second stop edge 76 on the top of the first clamp 71 and the second clamp 72 respectively, the inner liner is clamped upside down by manually operating the first hand-held rod 73 and the second hand-held rod 74. At this time, the first stop edge 75 and the second stop edge 76 form a stop space, which can better place the aluminum thermite welding plate and the heating tube on the bottom of the upside-down inner liner, play a good positioning role, facilitate the assembly of the aluminum thermite welding plate and the heating tube, and improve the assembly efficiency.

[0041] In order to better control the safety clamping structure 7, and facilitate the assembly and placement of the inner liner, the aluminum thermal welding plate and the heating tube, so as to improve production efficiency. A positioning support 8 is provided on the workbench 1; the bottom end of the positioning support 8 is provided with a first positioning slot 81 and a second positioning slot 82 that are respectively adapted to fit and position the first hand-held rod 73 and the second hand-held rod 74. First, manually operate the first hand-held rod 73 and the second hand-held rod 74 to clamp the inner liner upside down, and then respectively fit the first hand-held rod 73 and the second hand-held rod 74 into the first positioning slot 81 and the second positioning slot 82, so that the upside-down inner liner is suspended in the air, and then the aluminum thermal welding plate and the heating tube are assembled and placed, which is conducive to improving production efficiency.

[0042] In summary, the embodiment of the present invention provides a hot melt welding machine for hot melt welding between an inner liner and a heating tube, wherein the hot melt welding machine for hot melt welding between an inner liner and a heating tube has the following advantages:

[0043] 1. In the production of connection between the liner and the heating tube, a workbench 1, a rotating motor 2, an I-shaped turret 3, a lower hot pressing die assembly 4, a lifting assembly 5, an upper hot pressing die assembly 6 and a safety clamping structure 7 are set. The I-shaped turret 3 is driven by the rotating motor 2 to rotate, so that the lower hot pressing die assembly 4, the lifting assembly 5 and the upper hot pressing die assembly 6 rotate synchronously with the I-shaped turret 3. The lifting assembly 5 is used to adjust the position of the upper hot pressing die assembly 6, and accurately cooperates with the lower hot pressing die assembly 4 to ensure that the liner and the heating tube are tightly welded by aluminum heat fusion welding. With the rotation of the I-shaped turret 3, there is sufficient hot pressing fusion welding time, the connection between the liner and the heating tube is more stable, the welding quality is improved, and multiple welding stations can operate simultaneously, which significantly improves production efficiency.

[0044] 2. The combined design of the safety clamping structure 7 and the positioning support 8 makes assembly simple and convenient, and effectively prevents the inner liner from falling off or shifting during welding, ensuring the safety of the operator. At the same time, the operation of taking and placing the inner liner is simpler, reducing the difficulty of operation and improving work efficiency.

[0045] The above is only a preferred embodiment of the present application.
