DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] See also Figure 1-6 To illustrate the present embodiment, an electric control door includes a universal shaft 1, a first rotating shaft 4, a second rotating shaft 6, a connecting rod 10 and a reducer 14, wherein the first rotating shaft 4 is connected to the output shaft of the reducer 14 through the universal shaft 1, a branch pipe component is symmetrically installed on the first rotating shaft 4, a first shaft sleeve 5 is sleeved on the outer side of the branch pipe component, the second rotating shaft 6 is installed at one end of the control door body 17, a second shaft sleeve 8 corresponding to the position of the first shaft sleeve 5 is provided on the second rotating shaft 6, a connecting rod 10 is installed between the second shaft sleeve 8 and the first shaft sleeve 5, a bearing 12 is installed at the bottom of the first rotating shaft 4, and the bearing 12 is installed in a bearing support 11.

[0030] The connecting rod 10 is connected to the second rotating shaft 6 via a pin 7 and a fisheye joint 9 .

[0031] The branch pipe component includes a second branch pipe 2 and a third branch pipe 3 which are connected to each other at upper and lower ends. The second branch pipe 2 and the third branch pipe 3 are both sleeved on the outside of the first rotating shaft 4 .

[0032] The output shaft of the reducer 14 is hollow.

[0033] The reducer 14 of the device adopts a K series reducer. The output shaft of the reducer 14 is a hollow shaft type and can be directly used with the first rotating shaft 4. The first rotating shaft 4 only needs to be inserted into the output shaft of the reducer 14, thereby achieving the purpose of convenient operation and fast assembly. Then the reducer 14 starts to drive the first rotating shaft 4 to rotate, and then the first rotating shaft 4 can drive the connecting rod 10, so that the connecting rod 10 drives the second rotating shaft 6 to rotate. Through the rotation of the second rotating shaft 6, the opening of the control door body 17 is realized, and then the reducer 14 starts to drive the first rotating shaft 4 to rotate in the opposite direction. Through the above-mentioned operation method, the closing of the control door body 17 is realized. The opening and closing of the control door body 17 is controlled by the reducer 14, which avoids the risk of excessive temperature of the control door body 17 and scalding to the staff.

[0034] A travel switch positioning block is fixed on the clamp component on the upper part of the first sleeve 5 which is concentric with the outer end of the output shaft of the reducer 14. The position of the travel switch positioning block is the extreme position of the closed state and the open state of the control door body 17. The electrical signal generated by the collision of its contact with the contact head of the travel switch is activated, and the control reducer 14 drives the control door body 17 to turn to the closed or open position.

[0035] The upper and lower ends of the universal shaft 1 are both provided with universal joints 20, the middle outer side of the universal shaft 1 is sleeved with a hexagonal sleeve 22, the outer side of the universal shaft 1 between the hexagonal sleeve 22 and the universal joint 20 is sleeved with a connecting pipe 21, and the universal shaft 1 is made of hexagonal steel.

[0036] Since the reducer 14 drives a relatively long portal shaft, a pair of universal joints 1 for upper and lower alignment are provided at the end of the output shaft of the reducer 14. A universal joint 20 is installed at each end of the universal joint 1 to prevent the first rotating shaft 4 from getting stuck.

[0037] The device has a compact structure and flexible driving. It uses high-quality carbon steel profile 45# round steel to make the output shaft of the reducer 14 and ordinary carbon steel pipe profiles to make the first rotating shaft 4 and the second rotating shaft 6. The amount of mechanical processing and forming during assembly is small, and it is firmly welded to the steel structure door body. It is not only flexible to drive but also has an overall weight similar to that of a manual inspection door. The device has a travel switch limit function, that is, it controls the door body 17 to open to 90° or close to 0°. The travel switch interlocks and drives the reducer 14 to cut off the power and stop, and controls the door body 17 to close.

[0038] A wire feeding machine device comprises an electric control door, wherein the control door body 17 is mounted on the wire feeding machine device body, the reducer 14 is mounted on the reducer seat 15, the reducer seat 15 is mounted on the wire feeding machine device body through a flange plate 16, a protective shell 13 is installed on the outer side of the reducer 14, and the protective shell 13 is mounted on the wire feeding machine device body.

[0039] Since there is much dust on site, in order to make the device durable, the closing buffer 18 and the reducer 14 are both installed in the protective shell 13 to be sealed and dustproof.

[0040] A closing buffer 18 is installed in the protective shell 13 to reduce the vibration force generated on the wire feeding machine equipment frame when the control door body 17 is closed.

[0041] The embodiments of the utility model disclosed above are only used to help explain the utility model. The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
