DETAILED DESCRIPTION

[0020] The technical scheme in the utility model will be further described in connection with the drawings and embodiments.

[0021] As shown in the drawings, Figs. 1-3 The utility model discloses a large-chain driven ring-shaped refrigerator door body foaming line, which comprises:

[0022] The chain 5 is a transmission chain on the foaming line and is prior art.

[0023] The base 1 has two drive components 7 installed on it. The drive components 7 are electric push rods, cylinders or hydraulic cylinders. The output ends of the two drive components 7 are equipped with detachable brackets 2. The brackets 2 are U-shaped plates. The operation of the drive components 7 can drive the brackets 2 to move up or down.

[0024] Two drive rollers 4 are rotatably mounted on the bracket 2. The two drive rollers 4 are connected by a conveyor belt 3. The chain 5 abuts against the upper end of the conveyor belt 3 and is relatively stationary. A motor 6 is mounted on the bracket 2. The output end of the motor 6 is fixedly connected to the drive rollers 4. When the motor 6 works, it drives the drive rollers 4 to rotate. Under the transmission of the drive rollers 4 and the conveyor belt 3, the conveyor belt 3 can move. The chain 5 abuts against the conveyor belt 3 and moves synchronously. Therefore, the two are relatively stationary. This can stably support the chain 5 and reduce the friction on the conveyor belt 3. It mainly supports the chain 5 in the linear direction of movement. When turning or changing direction, there is sprocket support, so this device is not needed.

[0025] When it is necessary to adjust the tension of the support for the chain 5, the drive unit 7 can control the bracket 2 and the conveyor belt 3 to move up and down.

[0026] As the support frame 2 and conveyor belt 3 are used for a long time, they need to be disassembled for maintenance. Therefore, how to install the support frame 2 and the drive component 7? To achieve this, a connecting block 8 is fixedly connected to the bottom of the support frame 2. The bottom of the connecting block 8 is provided with a connecting groove 10. A positioning block 9 is slidably connected in the connecting groove 10. The positioning block 9 is fixedly connected to the output end of the drive component 7. The positioning block 9 is provided with a positioning groove 11. The connecting block 8 is provided with a positioning rod 14. The positioning rod 14 is slidably connected in the positioning groove 11 to lock the positioning block 9 in the connecting groove 10. A pull block 12 is fixedly fixed on the positioning rod 14. A spring 13 is fixedly fixed on the pull block 12. The other end of the spring 13 is fixedly connected to the connecting block 8. The spring 13 is in a stretched state. In this way, the spring 13, the pull block 12 and the positioning rod 14 generate a pulling force, so that the positioning rod 14 is stably locked in the positioning groove 11.

[0027] When maintenance is required on the bracket 2 and conveyor belt 3, the staff can manually pull the pull block 12 to move the positioning rod 14 out of the positioning groove 11. At this time, the positioning block 9 is no longer locked, so the bracket 2 can be moved up to remove it. This is simple and quick, making maintenance easier.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
