Description

Technical Field

[0001] The present invention relates to the technical field of thermos cup manufacturing equipment, and in particular to a bottom welding machine for special-shaped thermos cups. Background Art

[0002] The thermos cup is mainly composed of a thermos cup shell and a thermos cup base. During production, the thermos cup base and the thermos cup shell need to be welded together. At present, welding work in the thermos cup industry is mainly manual welding, and the shape of the thermos cup shell is mostly a regular cylinder. When aligning the thermos cup shell and the thermos cup base, you only need to press down the center of the thermos cup shell and the thermos cup base. However, as people's functional requirements for thermos cups continue to change, the shape of thermos cups has also changed. This results in the pressure plate tilting when pressing down the thermos cup shell and the thermos cup base when aligning the special-shaped thermos cup shell and the thermos cup base, resulting in poor neatness of the docking of the thermos cup shell and the thermos cup base. Therefore, previous welding equipment cannot manufacture new thermos cups.

[0003] Chinese patent CN216462810U discloses an automatic bottom welding machine for thermos cups. This welding machine has the following problems when used:

[0004] 1. When aligning the thermos cup shell and the thermos cup base, the accuracy is poor.

[0005] 2. It is impossible to produce thermos cups with special shapes, and it is impossible to press down the shell of the thermos cup stably. Summary of the Invention

[0006] The purpose of this technical solution is to provide a special-shaped thermos cup bottom welding machine, which uses a supporting device to achieve accurate alignment of the thermos cup shell and the thermos cup base, and uses a clamping device to stably clamp the thermos cup shell, thereby solving the problem of poor balance when producing special-shaped thermos cups.

[0007] The purpose of this technical solution is achieved in this way:

[0008] A special-shaped thermos cup bottom welding machine comprises: a frame; a supporting device, which is arranged on the frame, the supporting device includes a placement seat, the placement seat is used to support the thermos cup shell; and a pressing device, which is arranged on the frame and is used to press the thermos cup shell; wherein, the pressing device includes a pressing mechanism and a balancing mechanism, and the pressing mechanism includes a pressing part; the balancing mechanism includes: at least two balancing driving members; and at least two balancing abutting parts, which are both arranged at the output end of the balancing driving member and are symmetrically arranged on the pressing part; wherein, all the balancing abutting parts are synchronously lifted and lowered and movably abut the pressing part to maintain the pressing part to steadily press the thermos cup shell.

[0009] Preferably, the clamping mechanism includes: a clamping drive member, which is arranged on the frame; and a clamping rod, which is arranged at the output end of the clamping drive member; wherein the clamping portion is arranged at the lower end of the clamping rod.

[0010] Preferably, the clamping mechanism further includes a clamping mounting frame, which is arranged on the frame; the clamping rod is inserted into the clamping mounting frame through a clamping sleeve; the balancing drive member is arranged on the clamping mounting frame, and the balancing abutment portion is arranged through the clamping mounting frame.

[0011] Preferably, the surface of the pressing portion is provided with a plurality of recesses adapted to the balancing abutting portion; when the balancing abutting portion abuts against the pressing portion, the lower end of the balancing abutting portion is placed in the recess.

[0012] Preferably, the lower end of the pressing portion is concave to form a limiting groove adapted to the shell of the thermos cup.

[0013] Preferably, the supporting device includes: a supporting base, on which a placement seat is provided, and the placement seat is provided with a through hole; and a lifting mechanism, which is provided on the frame, and the lifting mechanism includes a lifting rod, and the lifting rod is movably placed in the through hole; wherein, the upper end of the lifting rod abuts against the base of the thermos cup.

[0014] Preferably, a countersunk hole is opened on the surface of the placement seat, the countersunk hole is connected to the through hole, and the countersunk hole is used to place the base of the thermos cup.

[0015] Preferably, the lifting mechanism includes: a lifting drive member, which is arranged on the frame; and a lifting rod, which is arranged at the output end of the lifting drive member and is used to push the thermos cup base upward out of the countersunk hole.

[0016] Preferably, the lifting mechanism further includes a lifting mounting frame, which is arranged on the frame; the lifting rod is inserted into the lifting mounting frame through a lifting shaft sleeve.

[0017] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0018] 1. During the descent of the clamping device designed in this technical solution, the balancing mechanism can ensure that the clamping part falls smoothly, and the phenomenon of xx caused by the center of gravity shifting when pressing down the special-shaped thermos cup will not occur, thereby improving the accuracy of alignment between the thermos cup shell and the thermos cup base.

[0019] 2. When the supporting device designed in this technical solution is working, it first completes the docking of the thermos cup shell and the thermos cup base in the countersunk hole, and then the thermos cup shell and the thermos cup base are pushed out as a whole by the lifting rod, leaving the connection seam to facilitate subsequent welding, thereby ensuring the alignment of the thermos cup shell and the thermos cup base.

[0026] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, a special-shaped thermos cup bottom welding machine is used to dock and press the special-shaped thermos cup shell 24 and the thermos cup base 25. It mainly includes a frame 1, a supporting device 2 and a pressing device 4. When in use, the thermos cup shell 24 and the thermos cup base are placed on the supporting device 2 and placed under the pressing device 4. After the pressing device 4 gradually descends and abuts the thermos cup shell 24, the two are pressed together with the supporting device 2.

[0028] like Figure 2 As shown, the clamping device 4 includes a clamping mechanism 5 and a balancing mechanism 6. The clamping mechanism 5 can be lifted and lowered vertically to press the thermos cup shell 24 onto the thermos cup base 25. The balancing mechanism 6 moves as a whole following the clamping mechanism 5 to assist the clamping mechanism 5 in lifting and lowering.

[0029] Furthermore, the clamping mechanism 5 includes a clamping drive 10, a clamping rod 11 and a clamping portion 7. The clamping drive portion is arranged above the frame 1. The clamping rod 11 is used to connect the clamping drive 10 and the clamping portion 7. The clamping portion 7 is cylindrical. When the thermos cup shell 24 is placed between the clamping portion 7 and the supporting device 2, the clamping portion 7 is vertically lifted and lowered and movably abuts against the upper end of the thermos cup shell 24.

[0030] Furthermore, the balancing mechanism 6 includes at least two balancing driving members 8 and at least two balancing abutting portions 9. In the present embodiment, the number of balancing driving members 8 and balancing abutting portions 9 is set to two, each balancing abutting portion 9 is arranged at the output end of the corresponding balancing driving member 8, and the two balancing abutting portions 9 are symmetrically arranged on the clamping portion 7. Since the thermos cup shell 24 is irregular in shape, when the clamping portion 7 is clamping the thermos cup shell 24, it may be offset, so the two symmetrically arranged balancing abutting portions 9 can effectively assist the clamping portion 7 to rise and fall smoothly.

[0031] like Figure 2 and Figure 3 As shown, the clamping mechanism 5 also includes a clamping mounting frame 12, which is arranged on the frame 1, and the clamping rod 11 is movably inserted into the clamping mounting frame 12 through the clamping sleeve 13. At the same time, the balancing drive member 8 is arranged on the clamping mounting frame 12, and the balancing abutment portion 9 is arranged through the clamping mounting frame 12.

[0032] Furthermore, the surface of the clamping portion 7 is provided with a plurality of recesses 14 adapted to the balancing abutment portion 9. When the balancing abutment portion 9 abuts against the clamping portion 7, the lower end of the balancing abutment portion 9 is placed in the recess 14. When the balancing abutment portion 9 and the recess 14 cooperate, the deviation of the balancing abutment portion 9 can be effectively prevented, thereby improving the stability of the lifting and lowering of the clamping portion 7.

[0033] Furthermore, the lower end of the pressing portion 7 is concave to form a limiting groove 15 adapted to the thermos cup shell 24 , and the limiting groove 15 is adapted to the shape of the upper end of the thermos cup shell 24 .

[0034] like Figure 4 and Figure 5 As shown, the supporting device 2 includes a supporting base 16 and a lifting mechanism 18. The supporting base 16 is arranged on the frame 1, and the placing seat 3 is arranged at the upper end of the supporting base 16. A countersunk hole 20 is opened on the surface of the placing seat 3. When the thermos cup base 25 and the thermos cup shell 24 are processed, both are first placed in the countersunk hole 20. At this time, the connecting seam between the two is also placed in the countersunk hole 20, which can ensure the accuracy of the docking between the two. The lifting mechanism 18 is used to push the thermos cup base 25 and the thermos cup shell 24 upward out of the countersunk hole 20 before welding them.

[0035] Furthermore, the placement seat 3 is provided with a through hole 17 , the countersunk hole 20 and the through hole 17 are connected to each other, and the lifting rod 19 of the lifting mechanism 18 is movably placed in the through hole 17 , and the lifting rod 19 is used to push the thermos cup base 25 out of the countersunk hole 20 .

[0036] Furthermore, the lifting mechanism 18 includes a lifting drive 21 and a lifting rod 19. The lifting drive 21 is arranged on the frame 1, and the lifting rod 19 is arranged at the output end of the lifting drive 21. In order to improve the stability of the lifting rod 19 during operation, a lifting mounting frame 22 is also provided. The lifting mounting frame 22 is arranged on the frame 1, and the lifting rod 19 is inserted into the lifting mounting frame 22 through a lifting shaft sleeve 23.
