DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 An automated column production line shown includes a conveyor chain 1 and a mounting frame 2. The conveyor chain 1 is installed on a conveyor track, and a motor and a sprocket drive the conveyor chain 1 to move, so that the conveyor chain 1 drives the columns to move to various workstations for processing. The conveyor chain 1 is an integrated production line of epoxy zinc-based polyester composite coating based on general chain conveying. Compared with traditional hot-dip galvanizing production lines and production lines of sporadic column manufacturers, it has the characteristics of stable product quality, high degree of automation, simple work flow, environmentally friendly raw materials, excellent anti-corrosion performance, etc. The mounting frame 2 is fixedly installed on the conveying path of the conveyor chain 1, and the interior of the mounting frame 2 is slidably connected to a connecting frame 3. The interior of the connecting frame 3 is rotatably installed with an adjusting wheel 4 for adjusting the tension of the conveyor chain 1. The adjusting wheel 4 follows the connecting frame 3, and the interior of the connecting frame 3 is fixedly installed with a fixed frame 8. One side of the fixing frame 8 is rotatably connected with a mounting shaft 9, and the outer wall of the mounting shaft 9 is rotatably sleeved with the adjusting wheel 4. A driving cylinder 5 is installed on the top of the mounting frame 2, and the output end of the driving cylinder 5 is transmission-connected with a limiting frame 6, and the limiting frame 6 is slidably connected to the inside of the mounting frame 2. A tension adjustment component 7 is arranged between the limiting frame 6 and the connecting frame 3, that is, the driving cylinder 5 drives the limiting frame 6 to move inside the mounting frame 2, so that the limiting frame 6 can drive the connecting frame 3 to move inside the mounting frame 2 through the tension adjustment component 7, thereby changing the position of the adjusting wheel 4, and then changing the distance of the conveying chain 1 passing through the path, so as to adjust the tension of the conveying chain 1, and the conveying chain 1 is provided with the mounting frame 2, the connecting frame 3, the adjusting wheel 4, the driving cylinder 5, the limiting frame 6 and the tension adjustment component 7 at multiple locations.

[0023] In particular, the tension adjustment assembly 7 includes a fixed rod 72 and a strong spring 71, the fixed rod 72 is installed at the bottom of the limit frame 6, the outer wall of the fixed rod 72 is slidably interlaced with the connecting frame 3, the strong spring 71 is slidably sleeved on the outer wall of the fixed rod 72, and the number of fixed rods 72 and strong springs 71 between the limit frame 6 and the connecting frame 3 is four, the limit frame 6 gives the connecting frame 3 an upward elastic tensile force through the strong spring 71, that is, when the conveying chain 1 is in a relaxed state, the limit frame 6 can drive the connecting frame 3 to rise through the strong spring 71, so that the connecting frame 3 drives the adjusting wheel 4 to rise inside the mounting frame 2, increasing the path of the conveying chain 1, thereby making the conveying chain 1 in a tensioned state, conversely, when the tension of the conveying chain 1 is too large, the adjusting wheel 4 can drive the connecting frame 3 to descend inside the mounting frame 2, so that the connecting frame 3 compresses the strong spring 71.

[0024] In particular, a fixing block 73 is fixedly connected to the bottom of the limit frame 6, and the bottom of the fixing block 73 is fixedly connected to the fixing rod 72. The bottom of the fixing rod 72 is fixedly connected to the limiting plate 74. The strong spring 71 is located between the limiting plate 74 and the connecting frame 3. The top of the limiting plate 74 is symmetrically fixedly connected with a positioning plate 75. The distance between the fixing block 73 and the positioning plate 75 is the movement distance of the connecting frame 3 relative to the limiting frame 6. A pressure sensor can be installed at the corresponding position of the positioning plate 75 and the fixing block 73 on the connecting frame 3. The model of the pressure sensor is JHBM-M1. The pressure sensor is squeezed to transmit an electrical signal, so that the electrical control system on the automated column production line controls the driving cylinder 5 to work through the received electrical signal, that is, when the bottom of the fixing block 73 is connected to the top of the connecting frame 3 When the top of the positioning plate 75 fits with the connecting frame 3 and squeezes the pressure sensor, the pressure sensor sends an electrical signal. At this time, the strong spring 71 is relaxed, so that the distance between the connecting frame 3 and the limit frame 6 is minimized, that is, the conveying chain 1 is still in a relaxed state, and the driving cylinder 5 can be used to drive the limit frame 6 to rise, thereby increasing the distance between the limit frame 6 and the connecting frame 3, thereby adjusting the tension of the conveying chain 1. When the top of the positioning plate 75 fits with the connecting frame 3 and squeezes the pressure sensor, the pressure sensor sends an electrical signal. At this time, the compression of the strong spring 71 reaches the maximum, and the distance between the connecting frame 3 and the limit frame 6 reaches the maximum. The conveying chain 1 is in an over-tensioned state, so the driving cylinder 5 can drive the limit frame 6 to descend, thereby reducing the distance between the limit frame 6 and the connecting frame 3.

[0025] Furthermore, the sides of the connecting frame 3 and the sides of the limiting frame 6 are fixedly connected with a connecting shaft 10, and the outer wall of the connecting shaft 10 is rotatably sleeved with a guide roller 11, which is rotatably set on the outside of the installation frame 2. The guide roller 11 can ensure the stability of the limiting frame 6 and the connecting frame 3 sliding up and down inside the installation frame 2.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
