[0024] Please specifically refer to Figures 1-4 , a pressing device, comprising a frame 1, a screw 2, a connecting block 3, a mounting plate 4, a motor 5, and a pressing assembly. The frame 1 is composed of an upper plate, a lower plate, and steel profiles arranged around the upper and lower plates for connecting the upper and lower plates. One end of the screw 2 is installed on the top of the frame 1, that is, on the upper plate of the frame 1. The connecting block 3 is installed on the screw 2, and a threaded hole cooperating with the screw 2 is provided on the connecting block 3. When the screw 2 is rotated, the connecting block 3 can be driven to move up and down on the screw 2. The mounting plate 4 is fixedly connected to the connecting block 3. The motor 5 is installed on the back of the mounting plate 4. The pressing assembly is installed on the output shaft of the motor 5. When the connecting block 3 moves up and down, the mounting plate 4, the motor 5, and the pressing assembly can be driven to move up and down together, that is, the height of the pressing assembly can be adjusted to adapt to different products.

[0025] Further, the pressing-down assembly includes an eccentric wheel 6, a connecting member 8, a connecting plate 9, an upper support plate 10, three guide posts 11, a pressing-down connecting plate 12, a first slider 13, a first guide rail 14, a support plate 15, and a pressing plate 16. The eccentric wheel 6 is installed on the output shaft of the motor 5. The connecting member 8 is installed on the eccentric wheel 6. The connecting plate 9 is installed on the connecting member 8. The connecting member 8 is provided with connecting heads at both ends. The two connecting heads are respectively connected to the eccentric wheel 6 and the connecting plate 9 to form an eccentric-wheel connecting-rod mechanism. The upper support plate 10 is installed on the connecting plate 9. The guide posts 11 are installed on the upper support plate 10. The pressing-down connecting plate 12 is installed on the guide posts 11. The first slider 13 is installed on the pressing-down connecting plate 12. The first guide rail 14 is adapted to the first slider 13. The support plate 15 is installed on the first slider 13. The pressing plate 16 is installed on the support plate 15. When the motor 5 works, the output shaft rotates to drive the eccentric wheel 6 to rotate together, thereby driving the connecting member 8 to move up and down and rotate relatively, and then driving the pressing plate 16 to move to press the product down.

[0026] Further, two second guide rails 17 are installed on the front surface of the mounting plate 4. The second guide rails 17 are provided with second sliders 18 adapted to the second guide rails 17. The connecting plate 9 is connected to the second sliders 18. The second guide rails 17 and the second sliders 18 limit the movement direction of the connecting plate 9, so that the connecting plate 9 can only move up and down, and thus the pressing plate 16 can move up and down.

[0027] Further, a plurality of connecting holes 19 are provided on the eccentric wheel 6. The distance between the center of each connecting hole 19 and the center of the eccentric wheel 6 is different. The connecting member 8 can be connected to different connecting holes, so as to finely adjust the moving height of the pressing plate 16.

[0028] Further, spring fixing plates 20 are provided on both sides of the same end of the pressing-down connecting plate 12 and the support plate 15. Springs 21 are installed on the spring fixing plates 20 of the pressing-down connecting plate 12 and the support plate 15.

[0029] This device is applied to the assembly line to press and finish the products on the assembly line. Therefore, when this device presses down, when the pressing plate 16 contacts the product, mutual forces will be generated, affecting the progress of the product. Due to the design of the first slider 13 and the first guide rail 14, the pressing plate 16 can follow the assembly line to move forward and then reset. At this time, it will not affect the forward movement of the product. And due to the design of the spring 21, the pressing plate 16 can be reset.

[0030] Further, a spring 22 is sleeved on the guide post 11.

[0031] Further, two strengthening and fixing supports 23 are installed between the connecting plate 9 and the upper support plate 10, strengthening the stability between the connecting plate 9 and the upper support plate 15.

[0032] Further, a third slider (not shown in the figure) is also installed on the back of the mounting plate 4. The third slider is adapted to the frame 1 and is hidden inside the frame 1 (section steel). Under the action of the third slider, the mounting plate 4 can move up and down along the frame 1 when the screw 2 is rotated.

[0033] Further, a handle 24 is installed at one end of the screw 2. The handle 24 makes it more convenient for the user to rotate the screw 2 and adjust the height of the pressing component.

[0034] In this embodiment, the pressing plate 16 is made of rubber. The pressing plate 16 is a replaceable type and is fixed to the support plate 15 through fasteners.

[0035] The present utility model is a pressing device, and its working principle is described in conjunction with the accompanying drawings of the specification:

[0036] This device is installed on the assembly line. After adjusting the height of the pressing plate 16, the product is placed on the square bar of the assembly line by a manipulator or manually. The product moves forward along the assembly line to below the pressing plate 16. The motor 5 works to drive the deflection wheel to rotate, driving the connecting member 8 to move up and down and rotate around the center of the deflection wheel. Furthermore, the second slider 18 and the connecting plate 9 make reciprocating up and down movements on the second guide rail 17, so that the pressing plate 16 can automatically make reciprocating up and down movements to press the product, making the heights of all products flush, which is convenient for spraying the products.

[0037] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
