DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] See also Figures 1 to 5The utility model provides a technical solution: a conveyor belt with a follow-up pressing function, comprising a pressing frame 1 and a conveying frame 2, at least one pressing frame 1 is arranged on one side of the conveying frame 2, the pressing frame 1 comprises a shell 10, two groups of pressing arms 11 are arranged on the shell 10, the ends of the pressing arms 11 are provided with cylinders 12, the output shaft ends of the cylinders 12 are provided with claw arms 13 for pressing, and the bottom of the shell 10 is also provided with a telescopic rod 100 for pushing the shell 10 to move up and down;

[0030] The height of the housing 10 can be adjusted by the telescopic rod 100 so that the device can be suitable for assembling bottles of different heights. The cylinder 12 on the pressing arm 11 can push the claw arm 13 to move downward, thereby pressing and assembling the handle placed on the bottle.

[0031] See also Figures 2 to 5 A driving module 3 is provided in the housing 10 for driving the pressing arm 11 to move left and right respectively; the driving module 3 includes a driving screw 30, a sliding seat 31 is provided on the driving screw 30, and the sliding seat 31 is fixedly connected to the side wall of the pressing arm 11 by screws, and positioning rails 32 are provided on both sides of the housing 10, and positioning seats 33 engaged with the positioning rails 32 are provided at both ends of the pressing arm 11. A servo motor 300 is provided on the housing 10, and a transmission belt 301 is provided at the output shaft end of the servo motor 300, and the other end of the transmission belt 301 is sleeved on the end of the driving screw 30;

[0032] The servo motor 300 drives the driving screw 30 through the transmission belt 301, so that the driving screw 30 drives the positioning seat 33 to move left and right in the shell 10, thereby adjusting the left and right position of the pressing arm 11, so that the working range of the single pressing arm 11 is expanded, and the pressing arm 11 can still perform the handle assembly work with the bottle body during movement. At the same time, the structure of the combination of two pressing arms 11 is adopted to further increase the working range of the pressing frame 1. Compared with the manual and single robot arm processing in the prior art, the processing efficiency of a single device in this structure is higher.

[0033] See also Figures 10 to 11 , symmetrically placed positioning side fences 20 are provided on both sides of the top of the conveying frame 2, an auxiliary moving belt 202 is provided inside the positioning side fence 20, and positioning shafts 203 penetrating the outer wall of the positioning side fence 20 are provided at two opposite side ends of the auxiliary moving belt 202, and a control motor 204 is provided on one of the positioning shafts 203;

[0034] The control motor 204 can drive the auxiliary moving belt 202 to rotate through the positioning shaft 203, so that when the positioning side rail 20 clamps the bottle body, the bottle body can move on the conveying frame 2. Therefore, during processing, there is no need to stop the conveying frame 2. Through the follow-up of the pressing arm 11 and the clamping effect of the positioning side rail 20, the assembly work of the handle placed on the bottle body can continue without stopping, thereby improving the processing efficiency of a single pressing frame 1, so that a single pressing frame 1 can assemble more handles per unit time.

[0035] See also Figures 6 to 9 A plurality of translation slides 21 are provided at the bottom of the positioning side rail 20, and the translation slides 21 correspond to each other in pairs, and left and right screw rods 22 are provided between the two corresponding translation slides 21, and a positioning rod 210 for mobile positioning is provided between the translation slides 21, and a direction-changing gear box 23 is provided in the center of the left and right screw rods 22, and a driving shaft 24 is provided on the direction-changing gear box 23, and a plurality of driving shafts 24 and the direction-changing gear box 23 are connected in series to all the left and right screw rods 22, and a coupling 25 is provided between the driving shaft 24 and the direction-changing gear box 23, and a driving belt 200 is provided on one side of the driving shaft 24 at the end, and a driving motor 201 is connected to the other end of the driving belt 200;

[0036] The driving motor 201 drives the driving shaft 24 to rotate through the driving belt 200. The driving shaft 24 drives the changing gear box 23 and drives the next driving shaft 24 to rotate through the coupling 25, so that all the changing gear boxes 23 in the device rotate synchronously, and then the spacing between the positioning side rails 20 is adjusted, so that the device can be suitable for the assembly of bottles with different diameters.

[0037] The working principle and use process of the utility model are as follows: first, the telescopic rod 100 is adjusted according to the height of the bottle body to which the handle is to be assembled, so that the housing 10 is moved to a suitable height, and at the same time, the translation slide 21 is adjusted according to the diameter of the bottle body to which the handle is to be assembled. When the driving motor 201 is started, the driving belt 200 drives the driving shaft 24 to rotate, so that the direction-changing gear box 23 drives the left and right screw rods 22 to rotate, so that the translation slide 21 at the corresponding position moves synchronously in different directions, thereby making the spacing between the positioning side rails 20 able to pass through bottles with different diameters;

[0038] Then, the bottle body is placed on the conveying rack 2, and the control motor 204 drives the auxiliary moving belt 202 to rotate through the positioning shaft 203, so as to move and push the bottle body between the positioning side rails 20. During the movement of the bottle body, a handle is placed on the bottle cap of the bottle. At this time, since the two positioning side rails 20 are not parallel to each other but have different inclination angles with the same center point, the moving direction of the bottle body can be adjusted by the cooperation of the positioning side rails 20 on both sides and the conveying rack 2, so that the bottle body can be moved to the right below the pressing arm 11.

[0039] Then, when the bottle body moves with the handle to the right below the pressing arm 11, the cylinder 12 pushes the claw arm 13 to assemble the handle. When performing this assembly action, the servo motor 300 can drive the driving screw 30 to rotate through the transmission belt 301, so that the sliding seat 31 moves on the driving screw 30, so that the pressing arm 11 moves along the positioning slide rail 32 with the bottle body through the positioning seat 33, so that the handle on the bottle body is assembled without stopping the conveying state of the conveying frame 2. After completing this assembly action, the driving motor 201 can be reversed or accelerated to rotate so that the pressing arm 11 can assemble the handle of the previous bottle body or the next bottle body. At the same time, the structure of the combination of two pressing arms 11 can further increase the working range of the pressing frame 1, and two groups of pressing arms 11 are set on a single pressing frame 10, so that the pressing work can be divided into two times to reduce the completion time of the pressing action of a single pressing arm 11, thereby further improving the assembly efficiency on the entire pressing frame 10.

[0040] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
