After the welded part cools down, use a specific die cutter to cut off the protruding part to meet the size requirements of the PET material in the subsequent process. If the production line personnel do not do a good job of shaping after welding, it is easy to cause the problem of blocking the sleeve in the later stage, affecting production efficiency and yield;

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0029] As shown in the figure, this embodiment provides a seamless welding device, including a workbench 1, a supporting component, a driving component, a moving component and a heating head 2, wherein:

[0030] The supporting components are provided in two groups, and the two groups of supporting components are symmetrically distributed on the workbench 1, and are used to support the PET panels to be welded;

[0031] The driving assembly is arranged between the supporting assemblies, and two heating heads 2 are arranged, and both of the two heating heads 2 face the PET panels to be welded, and are symmetrically installed on the driving end of the driving assembly, and are used to move toward or away from the PET panels to be welded under the action of the driving assembly;

[0032] The moving assembly is installed on the back of the driving assembly and is used to drive the heating head 2 on the driving assembly to move along the welding line.

[0033] In the above technical scheme, a pair of upper and lower symmetrical heating heads 2 are adopted, and the heating heads 2 are both facing the PET board to be welded on the supporting assembly, and cooperate with the driving assembly and the moving assembly, so that when welding is performed, the driving assembly can drive the two heating heads 2 to move toward the PET board until they contact the welding end, and the heating heads 2 are started for heating. During heating, the moving assembly drives the heating heads 2 to move back and forth in the direction of the welding line, so that while ensuring the heating effect, the heating heads 2 can simultaneously de-convex the weld to ensure the welding effect.

[0034] In order to realize the driving assembly driving the two heating heads 2, the driving assembly includes a driving motor 3, a threaded shaft 4, a synchronous sleeve 5 and a connecting column 6, wherein:

[0035] The threaded shaft 4 is fixedly mounted on the driving end of the driving motor 3. The threaded shaft 4 is provided with two groups of threads with opposite thread directions. A synchronous sleeve 5 is threadedly mounted on both groups of threads. The front side of the synchronous sleeve 5 is connected to the heating head 2 via a connecting column 6. When the driving motor 3 drives the threaded shaft 4 to rotate, the synchronous sleeves 5 on the two groups of threads with opposite thread directions approach or move away from each other, so as to drive the heating head 2 connected thereto via the connecting column 6 to move synchronously.

[0036] In order to ensure the stability of the heating head 2 connected to the synchronous sleeve 5 when moving, Figure 2 As shown, it also includes a stabilizing sleeve 7 and a stabilizing column 8. The stabilizing sleeve 7 is fixed to the back of the synchronous sleeve 5 and is sleeved on the outer surface of the stabilizing column 8. The stabilizing column 8 is fixed to the upper surface of the driving motor 3. By arranging the stabilizing sleeve 7 and the stabilizing column 8, the synchronous sleeve 5 can be restricted from moving along the axial direction of the stabilizing column 8 when it moves, thereby ensuring the stability of the heating head 2 connected to the synchronous sleeve 5 when it moves.

[0037] In order to realize the driving of the moving assembly to move the heating head 2 in the welding line direction, the moving assembly includes a first cylinder 9 and a moving seat 10, wherein:

[0038] The moving seat 10 is slidably mounted on the workbench 1, and the upper surface of the moving seat 10 is fixed to the driving motor 3;

[0039] The first cylinder 9 is disposed on the back side of the moving base 10 , and the extended end of the first cylinder 9 is fixed to the moving base 10 .

[0040] In order to realize the support assembly to support the PET plate to be welded, the support assembly includes a support column 11, a support plate 12, a second cylinder 13 and a push plate 14, wherein:

[0041] The support column 11 is disposed on the workbench 1, and one end of the support column 11 is fixed to the workbench 1, and the other end is fixed to the support plate 12;

[0042] The second cylinder 13 is disposed on the support plate 12, and the extended end of the second cylinder 13 faces the heating head 2 and is fixed to the push plate 14;

[0043] The support plates 12 on the two groups of supporting components are respectively used to support two PET plates to be welded. When welding, the second cylinder 13 can drive the push plate 14 to push the end of the PET plate to be welded to the corresponding position of the heating end of the heating head 2, and the second cylinders 13 on the two groups of supporting components exert force synchronously, which can play a role of fixed support for the two PET plates to ensure the welding effect.

[0044] Although the thickness of a pair of PET plates to be welded each time is matched, it cannot be guaranteed that the thickness of the PET plates to be welded each time is of the same specification. Therefore, it is necessary to adjust the height of the support plate 12 so that the two heating heads 2 can fully contact the upper and lower surfaces of the heated ends of the PET plates when moving toward the PET plates to be welded on the support plate 12. In this embodiment, the support column 11 is an electric push rod to adjust the height of the support plate 12, thereby meeting the welding requirements of PET plates of different thicknesses.

[0045] To sum up, the seamless welding equipment provided in this embodiment adopts a pair of symmetrical heating heads 2, and the heating heads 2 are both facing the PET panels to be welded on the supporting assembly, and cooperate with the driving assembly and the moving assembly, so that when welding, the two heating heads 2 can be driven by the driving assembly to move toward the PET panels until they contact the welding ends, and the heating heads 2 are started for heating. During heating, the heating heads 2 are driven by the moving assembly to reciprocate in the direction of the welding line, so that while ensuring the heating effect, the heating heads 2 can synchronously de-convex the welded parts to ensure the welding effect; by setting the stabilizing sleeve 7 and the stabilizing column 8, when the synchronous sleeve 5 moves, it can be limited to move along the axial direction of the stabilizing column 8, thereby ensuring the stability of the heating head 2 connected to the synchronous sleeve 5 when moving; by setting the support column 11 as an electric push rod, the height of the support plate 12 can be adjusted to meet the welding requirements of PET panels of different thicknesses.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
