Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular to a cardboard processing weighing device. Background Art

[0002] Cardboard processing weighing equipment is a vital tool in the cardboard converting industry. It is specifically designed to accurately and efficiently weigh lightweight but potentially bulky materials such as cardboard and cartons. This equipment plays a key role in ensuring product quality, controlling raw material consumption, and improving production efficiency.

[0003] However, in actual applications, cardboard is usually moved on a flatbed cart when being weighed. When the flatbed cart carries the cardboard to the weighing equipment for weighing, the bottom of the flatbed cart is moved by wheels, so the cardboard usually shakes on the weighing equipment along with the flatbed cart. The shaking will lead to inaccurate weighing results, and after the weighing is completed, it is more laborious to initially push the flatbed cart.

[0004] Therefore, those skilled in the art provide a cardboard processing weighing device to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the present application provides a cardboard processing weighing device.

[0006] The paperboard processing and weighing equipment provided in this application adopts the following technical solutions:

[0007] A cardboard processing weighing device includes a mounting plate, a weighing device is mounted on the upper end of the mounting plate, a fixing component is mounted on the upper end of the mounting plate and located outside the weighing device, the fixing component includes a mounting frame, a bidirectional screw rod is movably connected to the center of the inner side of the mounting frame, a first motor is fixedly connected to the center of the front end of the mounting frame, the output end of the first motor is fixedly connected to one end of the bidirectional screw rod, a moving block is threadedly connected to the outer side of the bidirectional screw rod at both ends, a clamping block is fixedly connected to the top of the moving block, and a pushing component is mounted on the inner side of the clamping block.

[0008] Preferably, the pushing assembly includes a second motor, which is fixedly connected to the outer wall on the other side of the clamping block. The output end of the second motor is fixedly connected to a rotating rod, and the outer side of the rotating rod is fixedly connected to a plurality of first gears. The inner side of the clamping block is movably connected to a plurality of rollers through the side wall, and the bottom end of the roller is fixedly connected to a second gear in the center, and the second gear is meshed with the first gear.

[0009] Preferably, the interior of the mounting frame and the positions on both sides are fixedly connected to limit rods, the bottom end of the clamping block and the positions near the front and rear ends are fixedly connected to two other moving blocks, and the other two moving blocks are slidably connected to the limit rods.

[0010] Preferably, a second sleeve is fixedly connected to the bottom end of the mounting frame, a second connecting rod is fixedly connected to the upper end surface of the weighing plate of the weighing device, and the second connecting rod is plugged into the second sleeve.

[0011] Preferably, the bottom end of the mounting frame is fixedly connected to the first sleeves at the four corners, the mounting plate is fixedly connected to the cylinders at the four corners, the telescopic end of the cylinder is fixedly connected to the first connecting rod, and the first connecting rod is plugged into the first sleeve.

[0012] In summary, this application has the following beneficial technical effects:

[0013] 1. The pneumatic cylinder, in conjunction with the first connecting rod and first sleeve, lifts the mounting frame and flatbed cart, ensuring the mounting frame is clear of the weighing equipment. The first motor, in conjunction with the bidirectional screw, limit rod, moving block, and clamping block, secures the flatbed cart. Once the flatbed cart is stable, the cylinder lowers the mounting frame into contact with the weighing equipment, extracting the first connecting rod from the first sleeve.

This provides a stable grip on the flatbed cart, effectively preventing it from shaking during weighing, significantly improving weighing accuracy. Furthermore, the push assembly drives the flatbed cart, assisting in its propulsion. BRIEF DESCRIPTION OF THE DRAWINGS
