[0031] Please refer to Figures 1-9 , the present invention provides a technical solution:

[0032] An adjustable chain storage conveyor belt, comprising a conveyor line frame 2, a positioning mechanism 12 and a control box 17. At least two parallel and width-adjustable conveying mechanisms are installed on the conveyor line frame 2. The width-adjustable conveying mechanism includes a conveying chain motor assembly 11. The positioning mechanism 12 is installed at the end of the conveyor line frame 2. The control box 17 is installed inside the conveyor line frame 2 and is controllably connected to the conveying chain motor assembly 11 and the positioning mechanism 12.

[0033] Specifically, each of the width-adjustable conveying mechanisms further includes a chain fixing line 3 and a sprocket chain assembly 6 parallel thereto, wherein: the chain fixing line 3 is fixedly installed on the conveyor line frame 2 through a plurality of groups of L-shaped support plates 1, and the sprocket chain assembly 6 is movably installed on the conveyor line frame 2. The chain fixing line 3 includes a sprocket fixing plate I 32, and the sprocket chain assembly 6 includes a sprocket fixing plate II 65. The sprocket fixing plate I 32 and the sprocket fixing plate II 65 are sleeved on a T-shaped screw rod 8. Both ends of the T-shaped screw rod 8 are installed on the conveyor line frame 2 through screw rod supports 18, and the end of the T-shaped screw rod 8 located at the L-shaped support plate 1 is installed on the sprocket fixing plate I 32 through a bearing 19. Movable sprockets 31 are installed at the front ends of the sprocket fixing plate I 32 and the sprocket fixing plate II 65, and fixed sprockets 31 are installed at the tail ends. The two sprockets 31 are driven by a chain 119, and a chain conveyor belt 16 is installed outside the sprockets 31. The sprocket fixing plate I 32 is fixedly installed on the conveyor line frame 2 through a plurality of groups of L-shaped support plates 1, and the sprocket fixing plate II 65 is sleeved on the T-shaped screw rod 8 through a T-shaped nut 61. A guide shaft 5 is also sleeved on the sprocket fixing plate I 32 and the sprocket fixing plate II 65 through linear bearings 66. Both ends of the guide shaft 5 are installed on the conveyor line frame 2 through guide shaft supports 4. A hand wheel 7 is installed at one end of the T-shaped screw rod 8. Chain lifting plates 62 are also provided on the sprocket fixing plate I 32 and the sprocket fixing plate II 65. The sprocket 31 at the tail end is sleeved on the input power shaft 10 through a bearing sleeve 67 and a bearing end cover 68. As Figures 2-5As shown in the figure, by rotating the handwheel 7 clockwise or counterclockwise, the T-shaped lead screw 8 is driven to rotate. Since the sprocket fixing plate I 32 is fixedly installed on the conveying line frame 2 by an array of L-shaped support plates 1, and a T-shaped nut 61 is provided on the sprocket fixing plate II 65, the sprocket fixing plate II 65 can move along the axial direction of the T-shaped lead screw 8 and the guide shaft 5 through the threaded fit between the T-shaped lead screw 8 and the T-shaped nut 61. Furthermore, the distance between the sprocket fixing plate I 32 and the sprocket fixing plate II 65 can be adjusted, achieving the function of adjusting according to the length of the product 125 and being applicable to multiple products, with extremely high versatility. By setting the chain supporting plate 62, the chain 119 can be supported, enabling the chain 119 on the first and last sprockets 31 to have a smoother running trajectory. By setting the linear bearing 66, the frictional resistance is reduced when adjusting the distance between the sprocket fixing plate I 32 and the sprocket fixing plate II 65, making the adjustment easier and more labor-saving.

[0034] Specifically, adjustment slots 33 are provided at the first ends of the sprocket fixing plate I 32 and the sprocket fixing plate II 65. The sprocket 31 at the first end is adjustably installed at the first ends of the sprocket fixing plate I 32 and the sprocket fixing plate II 65 through the idler adjustment block I 64 and the idler adjustment block II 63. The sprocket 31 at the last end is installed on the conveying line frame 2 through the input power shaft 10. As Figures 4-5 shown in the figure, the idler adjustment block II 63 is installed on the sides of the sprocket fixing plate I 32 and the sprocket fixing plate II 65. Among them, the idler adjustment block I 64 is coaxially installed with the sprocket 31 at the first end. By installing an adjustment bolt (not shown in the figure) between the idler adjustment block I 64 and the idler adjustment block II 63, the bolt can be rotatably fixed to either the idler adjustment block I 64 or the idler adjustment block II 63. Rotating the adjustment bolt can adjust the distance between the first and last sprockets 31 to adjust the tension of the chain 119 (and the chain conveyor belt 16).

[0035] Specifically, the conveying chain motor assembly 11 includes a motor 118, a motor support plate 113, and a motor adjustment bolt 116. A motor fixing plate 111 is installed on the motor support plate 113, and the motor 118 is installed on the motor fixing plate 111. A motor adjustment block 114 is installed on the top of the motor support plate 113. The motor adjustment bolt 116 threadedly penetrates through the motor adjustment block 114 and is in threaded linkage with the motor fixing plate 111. The motor 118 is drivingly connected to the input power shaft 10 and is fixed on the conveying line frame 2. A fixing plate 115 is vertically installed at the bottom of the motor support plate 113. The fixing plate 115 is fixed on the conveying line frame 2 through a motor fixing bracket 20. The output shaft of the motor 118 penetrates through the motor fixing plate 111 to install a gear I 120. A gear II 112 is installed in the middle of the input power shaft 10. The gear I 120 and the gear II 112 are linked by a chain. The control box 17 is control-connected to the motor 118. A motor support plate reinforcing rib 117 is installed between the motor support plate 113 and the fixing plate 115. The two ends of the input power shaft 10 are installed on the conveying line frame 2 through input shaft fixing plates 9. As Figures 6-7 shown, the control box 17 controls the operation of the motor 118. The rotation of the motor 118 causes the gear I 120 to drive the gear II 112 to rotate through the chain, thereby realizing the drive of the input power shaft 10. In this way, the two sprockets 31 at the tail end can be driven, and then the product 125 is transmitted between the head and tail sprockets 31 through the cooperation of the sprockets 31 and the chain. Due to the setting of the motor adjustment block 114 and the motor adjustment bolt 116 penetrating it, by rotating the motor adjustment bolt 116, the motor fixing plate 111 and the motor 118 can be adjusted and positioned up and down on the motor support plate 113.

[0036] Specifically, the positioning mechanism 12 includes a rodless cylinder 131, a lifting cylinder 129, and a feeding clamping cylinder fixing plate 123.

The control box 17 is control-connected to the lifting cylinder 129, the rodless cylinder 131, and the parallel clamp 130. As Figures 8-9As shown, when the product 125 is conveyed from the head end to the tail end by the chain conveyor belt 16 at the head end, it is detected by a sensor (not shown in the figure) and the control box 17, and then the rodless cylinder 131 is controlled to slide to the corresponding position, and adjusted to the appropriate height position by the lifting cylinder 129, and then the two parallel clamps 130 are controlled to clamp, so as to realize grasping the product 125 by lifting the claw 124 through two round bars.

[0037] Specifically, bolt lifting legs 14 and universal wheels 13 with brakes are installed at the four corners of the bottom of the conveyor line frame 2, and frame angle irons 15 are installed on the side of the conveyor line frame 2. As Figure 2 shown, installing the universal wheels 13 with brakes facilitates the movement of the conveyor belt, setting the bolt lifting legs 14 facilitates the height adjustment of the conveyor belt, and by setting the frame angle irons 15, it is convenient to install the conveyor belt to other places or equipment for work.

[0039] Specifically, for the present invention, only the product 125 needs to be placed on two adjacent chain conveyors 16 at the front end of the conveyor belt. The conveying chain motor assembly 11 controls the rotation of the chain fixing line 3 and the sprocket chain assembly 6 to feed the product to the end. After an inductor (not shown in the figure) senses the product 125, the control box 17 controls the positioning mechanism 12 to grasp the product 125 to achieve precise positioning of the product, waiting for the robot to grasp the product for loading and unloading. Among them, the handwheel 7 and the T-shaped screw rod 8 can control the left and right movement of the sprocket chain assembly 6; it can be adjusted according to the length of the product, and has the function of being applicable to multiple products, with extremely high versatility; Equipment part analysis: The sprocket chain assembly 6 is composed of a T-shaped nut 61, a chain support plate 62, an idler adjustment block II 63, etc. Among them, the conveying chain motor assembly 11 is controlled by a motor fixing plate 111, a chain, etc. Among them, the motor support plate reinforcing rib 117 and the motor support plate 113 are installed at the fixing plate 115, the motor fixing plate 111 is installed on the motor support plate 113, the motor 118, the motor adjustment plate (i.e., the motor adjustment block 114), and the chain are installed at the motor fixing plate 111, the gear II 112 is installed at the chain, and the gear I 120 is installed on the output shaft of the motor; the T-shaped nut 61 and the linear bearing 66 are both installed on the sprocket fixing plate II 65; the chain fixing line 3 is composed of a sprocket 31, a chain support plate 62, etc. Among them, the sprocket 31, the idler adjustment block II 63, and the idler adjustment block I 64 are all installed on the sprocket fixing plate I 32; the positioning mechanism 12 is composed of a rodless cylinder fixing plate 121, a lifting cylinder adapter plate 122, etc. Among them, the rodless cylinder 131 is installed on the rodless cylinder fixing plate 121, the bottom fixing plate 126 of the lifting cylinder, the side fixing plate 127 of the lifting cylinder, and the reinforcing rib 128 of the lifting cylinder fixing plate are installed on the rodless cylinder 131, the TCL25*75S cylinder (lifting cylinder 129) is installed on the side fixing plate 127 of the lifting cylinder, the lifting cylinder adapter plate 122 is installed on the TCL25*75S cylinder, the feeding clamping cylinder fixing plate 123 is installed on the lifting cylinder adapter plate 122, the SGM16*10 parallel clamp 130 is installed on the feeding clamping cylinder fixing plate 123, and two round rod lifting claws 124 are respectively installed on the SGM16*10 parallel clamp 130.
