[0045] 10. Guide wheel; 11. Support leg. Detailed Implementation

[0046] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0047] Example 1

[0048] like Figures 1-6 As shown in this embodiment, a telescopic conveyor is provided, including a fixed frame 1, which is supported by support legs 11. A movable frame 2 is slidably attached to one end of the fixed frame 1. The fixed frame 1 and the movable frame 2 are provided with a wheel set 3. The wheel set 3 includes a drive wheel 301, a fixed guide wheel 302, a first movable wheel 303, and a second movable wheel 304. The drive wheel 301 and the fixed guide wheel 302 are rotatably connected to the fixed frame 1. The first movable wheel 303 and the second movable wheel 304 are rotatably connected to both ends of the movable frame 2, respectively. A conveyor belt 4 forming a closed loop is wound around the drive wheel 301, the fixed guide wheel 302, the first movable wheel 303, and the second movable wheel 304. The conveyor belt 4 between the fixed guide wheel 302 and the second movable wheel 304 is horizontally arranged and is used to transport items.

[0049] The conveyor belt 4 between the fixed guide wheel 302 and the first movable wheel 303, the conveyor belt 4 between the first movable wheel 303 and the second movable wheel 304, and the conveyor belt 4 between the drive wheel 301 and the second movable wheel 304 are arranged in parallel.

[0050] like Figure 1 As shown, in order to drive the conveyor belt 4 to rotate, a first motor 8 is fixedly installed on the side wall of the fixed frame 1. The output shaft of the first motor 8 is connected to one end of the drive wheel 301 through a coupling. When the first motor 8 starts, the conveyor shaft of the first motor 8 drives the drive wheel 301 to rotate, thereby driving the conveyor belt 4 to rotate.

[0051] Work process:

[0052] When the telescopic conveyor needs to be started for transporting goods, the first motor 8 is started first. The output shaft of the first motor 8 is connected to one end of the drive wheel 301 via a coupling. Therefore, when the first motor 8 starts, its output shaft rotates, thereby driving the drive wheel 301 to rotate. The rotation of the drive wheel 301 is transmitted to the fixed guide wheel 302, the first movable wheel 303, and the second movable wheel 304 through the friction of the conveyor belt 4, causing the entire conveyor belt 4 to begin cyclical motion.

[0053] Because the conveyor belt 4 between the fixed guide wheel 302 and the movable wheel 303 is horizontally positioned, items can be placed smoothly on this conveyor belt for transport. The continuous movement of the conveyor belt 4 transports items from one end to the other, achieving continuous transport of items.

[0054] When the movable frame 2 needs to be adjusted in length, the length of the conveyor is changed by sliding the position of the movable frame 2. During the adjustment, the movable wheels 303 and 304 move with the movable frame 2, but the continuity and movement of the conveyor belt 4 are not affected, ensuring the stability and reliability of the conveyor.

[0055] The entire telescopic conveyor works smoothly and efficiently and is suitable for various occasions requiring continuous conveying of articles.

[0056] Embodiment Two

[0057] As shown in Figures 1-5 , based on Embodiment One, in order to enable the movable frame 2 to slide on the fixed frame 1, two oil cylinders 5 are symmetrically and fixedly installed on the side walls of the fixed frame 1, and the output shaft ends of the two oil cylinders 5 are fixedly connected to the side walls of the movable frame 2; when the output shaft of the oil cylinder 5 extends or retracts, the movable frame 2 can slide on the fixed frame 1.

[0058] The movable frame 2 includes two side rods 201, which are respectively arranged on the two sides of the fixed frame 1, and a fixed sleeve 6 is fixedly connected to each side of the fixed frame 1. The two side rods 201 respectively slide in the same side fixed sleeve 6.

[0059] The movable frame 2 includes an inner support 202, which is slidingly connected to the inside of the fixed frame 1. The inner support 202 is provided with at least one support roller 7 for supporting the conveyor belt 4.

[0060] Embodiment Three

[0061] As shown in Figure 2 and Figure 5 , based on the above embodiments, in order to tension the conveyor belt 4, a tensioning assembly 9 is arranged on the fixed frame 1. The tensioning assembly 9 includes a sliding frame 901, which is slidingly connected to the inside of the fixed frame 1. A tensioning wheel 902 for tensioning the conveyor belt 4 is rotatably connected to the sliding frame 901. Two guide rods 903 are fixedly connected to the side walls of the fixed frame 1. Two slide sleeves 904 are fixedly connected to the side walls of the sliding frame 901 and are respectively slidingly sleeved on the two guide rods 903.

[0062] The tensioning assembly 9 further includes a pull plate 905, which is slidingly sleeved on the two slide sleeves 904. A threaded sleeve 906 is fixedly connected to the pull plate 905. A screw rod 907 is rotatably connected to the fixed frame 1 by a second motor 908, and is meshingly connected in the inside of the threaded sleeve 906, as shown in Figure 5As shown, the second motor 908 is fixedly installed on the fixed frame 1, and the output shaft of the second motor 908 is fixedly connected with one end of the screw rod 907, so that the output shaft of the second motor 908 can drive the screw rod 907 to rotate when the second motor 908 is started; the sliding sleeve 904 is provided with a spring 909 for pressing the pull plate 905; the fixed frame 1 is rotatably connected with a guide wheel 10 for guiding the conveying belt 4.

[0063] Working process:

[0064] When it is necessary to adjust the tension of the conveying belt 4, the second motor 908 is started. The output shaft of the second motor 908 rotates to drive the screw rod 907 fixedly connected therewith to rotate. Since the screw rod 907 is in meshing connection with the threaded sleeve 906, the rotation of the screw rod 907 drives the threaded sleeve 906 to move. The movement of the threaded sleeve 906 is transmitted to the sliding frame 901 through the pull plate 905, so that the sliding frame 901 slides in the fixed frame 1 under the guidance of the guide rod 903. The sliding of the sliding frame 901 drives the tensioning wheel 902 to move, so as to exert a tensioning force on the conveying belt 4.

[0065] During the sliding of the sliding frame 901, the pull plate 905 compresses the spring 909. The compression force of the spring 909 is transmitted to the sliding frame 901 through the pull plate 905 and the sliding sleeve 904, so as to elastically tension the conveying belt 4. This elastic tensioning mode can increase the service life of the conveying belt 4 and avoid damage of the conveying belt 4 due to excessive tightness or relaxation.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present application can still be modified or replaced equivalently without departing from the spirit and scope of the present application, and any modification or partial replacement should be covered in the scope of the claims of the present application.
