[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood. It should be noted that when a component is referred to as "fixed to" another component, it can be directly on the other component or there can also be a central component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and are not intended to be the only implementation method. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] See also Figures 1 to 4 As shown, in this embodiment, an automatic weighing mechanism of a car roof PU rubber rolling line includes a frame 1, a material pulling movable frame 2 and an automatic weighing frame 3, two sets of synchronous belt drive modules 4 are installed on both sides of the frame 1, one end of the two sets of synchronous belt drive modules 4 is connected to a transmission shaft 5, and a servo motor 6 is connected to the transmission shaft 5 through a coupling, and both sides of the material pulling movable frame 2 are fixed to the synchronous belts of the two sets of synchronous belt drive modules 4 through clamping plates respectively, and the servo motor 6 drives the transmission shaft 5 to rotate, thereby driving the material pulling movable frame 2 to reciprocate along the frame 1.

[0021] Two lifting cylinders 8 are installed on the material pulling movable frame 2 at intervals through a mounting plate 7. The piston rods of the two lifting cylinders 8 are arranged downward and a connecting block 9 is arranged at the end of the piston rod. A clamping cylinder 10 is fixed on the connecting block 9. The clamping cylinder 10 is used to clamp and feed the canopy products. By adjusting the installation spacing of the two lifting cylinders 8 on the material pulling movable frame 2, it can adapt to the feeding of canopy products of different widths.

[0022] The four corners of the frame 1 are fixed with support platforms 11. The automatic weighing frame 3 includes a base frame 30. The four corners of the base frame 30 are placed on the support platforms 11. Pressure sensors for weighing are arranged between the support platforms 11 and the four corners of the base frame 30. A plurality of support rods 31 are arranged in parallel and at intervals above the base frame 30. A vertical rod 32 is connected to the bottom of the support rod 31. The vertical rod 32 can be detachably installed on the base frame 30 through a connecting seat 33. Both ends of the support rod 31 are bent downward to facilitate the smooth entry and exit of the canopy product. The design of the automatic weighing frame 3 mainly takes into account the particularity of the large surface area and light weight of the canopy product. The support structure using multiple support rods 31 is not only conducive to the accuracy of weighing, but also greatly reduces the surface area of ​​the canopy product and the support structure, and prevents the glue on the canopy product from sticking to the support structure.

[0023] A receiving groove 12 for collecting the residual materials dropped during the material pulling process is installed at the bottom of the frame 1.

[0024] During operation, the servo motor 6 drives the material pulling movable frame 2 to the material pulling station, and the lifting cylinder 8 drives the clamping cylinder 10 to descend to the clamping position, and one end of the ceiling product is clamped by the clamping cylinder 10. Then the servo motor 6 drives the material pulling movable frame 2 to return to its position, and the clamping cylinder 10 is released, and the ceiling product is moved to the automatic weighing frame 3. After the weighing is completed, the external equipment moves the weighed ceiling product to the next process.
