[0028] The utility model provides Figure 1-7 A chain conveyor with automatically changing edge protection spacing as shown in the figure comprises:

[0029] A fuselage 100, with tensioning assemblies 101 provided at both ends of the fuselage 100, the tensioning assemblies 101 comprising a tensioning block 1011 fixedly connected to the fuselage 100 and a tensioning wheel 1012 rotatably connected to the tensioning block 1011, a chain groove 102 provided inside the fuselage 100, a chain 103 sleeved on the tensioning wheel 1012 provided inside the chain groove 102, and the spacing between the tensioning wheels 1012 at both ends of the fuselage 100 can be changed by adjusting the inclination of the tensioning block 1011, thereby achieving tensioning of the chain 103;

[0030] The driving assembly 200 includes an installation box 201 fixed to the bottom of the fuselage 100. A motor 202 and a transmission shaft 203 connected to the motor 202 are arranged in the installation box 201. Sprocket wheels 204 meshing with the chain 103 are fixed at both ends of the transmission shaft 203. The transmission shaft 203 is driven to rotate by the motor 202, and the transmission shaft 203 drives the chain 103 to rotate through the sprocket wheel 204, thereby providing power support for the transportation of the pallet 600 and the goods.

[0031] The guardrail assembly 300 includes a guide guardrail 301 and a cylinder fixing plate 302 arranged on one side of the guide guardrail 301. The longitudinal section of the cylinder fixing plate 302 is an L-shaped structure. The cross plate of the cylinder fixing plate 302 is fixedly connected to the mounting frame at the bottom of the guide guardrail 301. A slider assembly 303 is provided at the bottom of the guide guardrail 301. A cylinder 304 is fixed on the cylinder fixing plate 302. The piston rod of the cylinder 304 is fixedly connected to the guide guardrail 301. The extension and retraction of the piston rod of the cylinder 304 can drive the guide guardrail 301 to move, thereby changing the distance between the two guide guardrails 301.

[0032] The barcode scanner assembly 400 includes a barcode scanner 401, a fixing bracket 402 for mounting the barcode scanner 401, and a mounting plate 403 for mounting the fixing bracket 402, wherein the mounting plate 403 is fixed between the fuselage 100.

[0033] In addition, it also includes a support assembly 500, which is arranged at the bottom of the fuselage 100 and the guardrail assembly 300, and can provide support for the fuselage 100 and the guardrail assembly 300. The support assembly 500 includes a support leg 501 and an adjustment foot 502 fixed at the bottom of the support leg 501, so as to facilitate the adjustment of the height of the support leg 501 according to actual needs.

[0034] Specifically, it also includes a pallet 600, which is arranged on the top of the fuselage 100. The length of the pallet 600 is not less than the distance between the two chains 103 and not greater than the distance between the two guide guardrails 301, ensuring that the pallet 600 can be transported to the designated position through the chain 103, and at the same time ensuring that the guide guardrail 301 can guide the pallet 600.

[0035] It is worth mentioning that fixed blocks 205 are provided at the four corners of the top of the installation box 201, and guide wheels 206 are rotatably connected to the fixed blocks 205, so that the chain 103 can enter the installation box 201 through the guide wheels 206 and engage with the sprocket 204 to ensure that the power output by the motor 202 can be transmitted to the chain 103.

[0036] Specifically, the slider assembly 303 is arranged at the two ends of the bottom of the guide guardrail 301. The slider assembly 303 includes a slide rail 3031, a slider 3032 slidably connected to the top of the slide rail 3031, and a slider block 3033 fixedly connected to the two ends of the slide rail 3031. The slider 3032 is fixedly connected to the guide guardrail 301, so that the guide guardrail 301 can make a linear reciprocating motion on the slide rail 3031 through the slider 3032. By setting the slider block 3033, the slider 3032 can be effectively prevented from detaching from the slide rail 3031.

[0037] It should be noted that the top horizontal height of the guide guardrail 301 is not lower than the bottom horizontal height of the pallet 600, and the bottom horizontal height of the guide guardrail 301 is not higher than the top horizontal height of the pallet 600, to ensure that the guide guardrail 301 can push the pallet 600 to move when making a linear motion along the slide rail 3031. When the two guide guardrails 301 are respectively attached to the two sides of the pallet 600, pallets 600 of different sizes can be guided.

[0038] Specifically, a barcode matching the barcode scanner 401 is provided on one side of the tray 600. The barcode scanner 401 and the cylinder 304 are both electrically connected to the external control device. The barcode scanner 401 obtains the specification information of the tray 600 by scanning the barcode on the tray 600, and sends the information to the external control device for processing. The external control device then controls the cylinder 304 accordingly based on the processed information, so that the piston rod of the cylinder 304 extends or contracts a specified length.

[0039] Working principle: When the chain conveyor that automatically changes the spacing of the edge guards is used, first place the pallet 600 at one end of the fuselage 100, and then place the goods on the pallet 600. At this time, start the motor 202, the motor 202 drives the transmission shaft 203 to rotate, and drives the chain 103 to move through the sprocket 204 on the transmission shaft 203. The pallet 600 moves toward the other end of the fuselage 100 driven by the chain 103. When the pallet 600 passes the barcode scanner 401, the barcode scanner 401 obtains the specification information of the pallet 600 by scanning the barcode on the pallet 600, and then the cylinder 304 makes a corresponding action to drive the guide guardrail 301 to move, completing the spacing adjustment of the guide guardrail 301. Finally, the pallet and the goods are guided and transported to a specific position through the chain 103. The chain conveyor that automatically changes the spacing of the edge guards has an advanced design, a compact structure, and is easy to use. By setting a barcode scanner 401, it can scan the code to identify the specifications of the pallet 600, and then the cylinder 304 makes a corresponding action to push or pull the guide guardrail 301 to move, thereby adjusting the spacing of the guide guardrail 301, and then it can adaptively convey and guide pallets 600 of various specifications, with a wider range of applications and strong adaptability.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to 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 utility model shall be included in the protection scope of the present utility model.
