Description

Technical Field

[0001] This utility model relates to the field of Christmas tree technology, and in particular to a Christmas tree tube production device. Background Technology

[0002] A Christmas tree is an evergreen tree, typically a fir or pine, decorated with lights and ornaments. As an important element of Christmas, it is one of the most famous traditions in Christmas celebrations. Traditionally, Christmas trees were made from trees felled from forests. However, due to environmental protection requirements, artificial Christmas trees made of plastic are now generally used. Besides being inexpensive and lightweight, they are also reusable. When placing an artificial Christmas tree, its bottom end needs to be inserted into a support bracket. Existing support bracket manufacturing devices, such as the patented (CN114952156A) automatic welding fixture for Christmas tree legs, use a split-type clamping system. The separate part of the welding fixture positions the central tube of the Christmas tree leg relative to the support leg. After welding, the entire product can be easily and quickly removed, shortening the product clamping cycle. However, its overall structure is relatively complex and inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Christmas tree pin production device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A Christmas tree tube production device is designed, comprising a base, a second electric cylinder on the upper surface of the base, a telescopic rod on the top of the second electric cylinder, a first electric cylinder at the end of the telescopic rod, a connecting rod connected to the bottom of the first electric cylinder, a second electrode on the connecting rod, the second electrode being connected to an external welding host via a wire, a third electrode on the upper surface of the base, the third electrode being connected to the external welding host via a wire, a tube support on the upper surface of the third electrode, and a Christmas tree tube clamped between the tube support and the second electrode.

[0006] Preferably, the pin bracket includes two pairs of arc-shaped supports, one pair of which has a slot at its end and the other pair of arc-shaped supports has a plug at its end that can be inserted into the slot.

[0007] Preferably, the upper end face of the tube bracket is provided with an annular groove for insertion into the Christmas tree sleeve.

[0008] Preferably, the upper surface of the base is provided with a welding bracket, and the tube foot bracket is snapped onto the welding bracket.

[0009] Preferably, the bottom of the connecting rod is connected to the first electrode via a spring, the first electrode is connected to an external welding host via a wire, and the first electrode abuts against the upper end face of the pin bracket.

[0010] Preferably, the outer wall of the telescopic rod is connected to a sliding rod, and a slip ring is slidably provided on the outer wall of the sliding rod. The slip ring is connected to a connecting sleeve through a crossbar, and the connecting sleeve is fitted onto the outer wall of the Christmas tree sleeve.

[0011] The present invention proposes a Christmas tree tube foot production device, which has the following advantages: by setting a first electrode, a second electrode, and a third electrode, the Christmas tree sleeve is clamped between the first electrode, the second electrode, and the third electrode. When the first electric cylinder drives the connecting rod to move down, the second electrode abuts against the top of the Christmas tree sleeve, and the tube foot bracket is clamped between the first electrode and the third electrode. This allows the welding and fixing work between the Christmas tree sleeve and the welding bracket to be completed when the first electric cylinder moves down. The entire welding process is relatively simple, easy to operate, and improves the processing efficiency of the Christmas tree tube feet. Attached Figure Description
