Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging compression bag production equipment, in particular to a shock absorbing mechanism of a vacuum packaging compression bag printing, composite molding integrated machine. Background Art

[0002] A multifunction printing machine is a machine that integrates multiple processes, including printing, die-cutting, laminating, sheet cutting, punching, and labeling. It is primarily used to produce a variety of packaging materials. This machine is commonly used to produce plastic bags, wrapping paper, composite films, and other packaging materials. Its versatility and high efficiency meet the production needs of packaging materials of varying specifications and materials. Furthermore, a multifunction printing machine can flexibly switch between multiple printing methods, ensuring printing quality and production efficiency. It is widely used in industries such as food and pharmaceuticals, not only improving product packaging quality and brand image, but also increasing production efficiency and reducing production costs, providing a significant boost to the development of various industries.

[0003] Based on the above, the inventors found that the following problems exist: in the process of die-cutting the current vacuum packaging compression bags using a printing compound machine, when the impact force of the upper die-cutting knife pressing down is too large and it is in continuous mechanical operation, the lower die-cutting knife and the workbench will vibrate, thereby reducing the accuracy of the die-cutting of the compression bag material.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a shock-absorbing mechanism of a vacuum packaging compression bag printing and composite molding all-in-one machine is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose of the utility model is to provide a shock absorbing mechanism for a vacuum packaging compression bag printing and composite molding all-in-one machine, so as to solve the problems raised in the above-mentioned background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] The shock-absorbing mechanism of the vacuum packaging compression bag printing and composite molding all-in-one machine includes a die-cutting mechanism, which includes a base, a square groove is opened at the inner center of the base, a square plate is provided inside the square groove, and shock-absorbing mechanisms are provided at the four corners of the bottom end of the square plate. The four shock-absorbing mechanisms all include a connecting tube, the bottom surface of the connecting tube is connected to the inner bottom end of the square groove, and a connecting rod is movably inserted in the upper end of the connecting tube, the bottom end of the connecting rod is connected to a piston, one side of the outer wall of the piston is pressed against the inner wall of the connecting tube, and the end of the connecting rod away from the piston is connected to a circular plate, the top surface of the circular plate is connected to the bottom surface of the square plate, and the outer sleeve of the connecting tube is provided with a shock-absorbing spring, and the two ends of the shock-absorbing spring are respectively connected to the bottom surface of the circular plate and the inner bottom surface of the square groove.

[0008] Furthermore, the interior of the connecting cylinder is filled with buffer oil, and both sides of the outer wall of the connecting cylinder are connected with flow pipes, and the flow pipes are away from the outer wall of the connecting cylinder and the inner wall of the shock-absorbing spring.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that since the interior of the connecting cylinder is filled with buffer oil, when the square plate, the placement seat and the lower die cutter are subjected to collision and vibration, the shock-absorbing spring will be compressed, and the connecting rod will be squeezed downward, causing the piston to squeeze the buffer oil. The squeezed buffer oil will enter the circulation tube through the oil inlet located below the connecting cylinder, and then enter the circulation tube through the oil outlet located above the connecting cylinder to flow out, so that the buffer oil is located above the piston, and the flow of the buffer oil is used to form damping, and cooperate with the shock-absorbing spring to absorb impact energy, thereby reducing the vibration of the square plate, the placement seat and the lower die cutter.

[0010] Furthermore, a sealing ring is provided at the inner upper end of the connecting tube, and the inner wall of the sealing ring is in contact with the outer wall of the connecting rod.

[0011] The beneficial effect of adopting the above further solution is that, by providing a sealing ring, leakage of the buffer oil inside the connecting cylinder is avoided.

[0012] Furthermore, the upper end surface of the square plate is connected to a placement seat, the interior of the placement seat is connected to a lower die cutter, the upper end surface of the base is connected to a portal frame, a hydraulic rod is provided at the center of the upper end surface of the portal frame, the movable end of the hydraulic rod passes through the portal frame and is connected to a connecting seat, the bottom end of the connecting seat is connected to a connecting block, and the bottom end of the connecting block is connected to an upper die cutter.

[0013] The beneficial effect of adopting the above further solution is that by providing a hydraulic rod, when the hydraulic rod is started, its movable end can push the connecting seat, the connecting block and the upper die cutting knife downward.

[0014] Furthermore, the upper end surface of the square plate is located on the front and back of the placement seat and is provided with clamping components, and the two clamping components each include a pair of electric telescopic rods, and the movable ends of the pair of electric telescopic rods are connected to a pressure plate.

[0015] The beneficial effect of adopting the above further solution is that by setting up the electric telescopic rod, when a pair of electric telescopic rods at the same level are working, it is easy to realize the lifting and lowering of the pressure plate connected between the upper end surfaces of the movable ends of the pair of electric telescopic rods.

[0016] Furthermore, one side of the bottom end of the pressing plate is in contact with the upper end surface of the placement seat, and the opposite ends of the two pressing plates are flush with one side of the inner wall of the placement seat close to the electric telescopic rod.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that when the pressure plate moves upward, it is convenient to place the compression bag material to be die-cut on the placement seat. When the pressure plate moves downward, the bottom end side of the pressure plate is in contact with the upper end surface of the placement seat, thereby facilitating the fixing of the compression bag material placed on the placement seat.

[0018] Furthermore, a circular hole is formed on the upper end surface of the square plate at the electric telescopic rod, the bottom end of the electric telescopic rod extends into the inside of the circular hole, and the outer wall of the electric telescopic rod is connected to the inner wall of the circular hole.

[0019] The beneficial effect of adopting the above further solution is that by setting a circular hole, the electric telescopic rod is inserted into the circular hole, and the outer wall of the end of the electric telescopic rod away from the movable end is connected to the inner wall of the circular hole, thereby facilitating the connection between the electric telescopic rod and the square plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the shock absorbing mechanism of the vacuum packaging compression bag printing and composite molding all-in-one machine, during the die-cutting process of the compression bag, when the hydraulic rod is started, the connecting seat, the connecting block and the upper die-cutting knife are moved downward, and then the compression bag material is die-cut. At the same time, the bottom of the upper die-cutting knife will contact the upper end surface of the lower die-cutting knife, and the pressure of the upper die-cutting knife will drive the square plate to press down. During the process of the square plate pressing down, the shock absorbing spring will be compressed, and the connecting rod will be squeezed downward, so that the piston will squeeze the buffer oil. The squeezed buffer oil will be located under the connecting cylinder through the circulation pipe. The oil inlet of the square enters the circulation pipe, and then flows out of the circulation pipe from the oil outlet located above the connecting cylinder, so that the buffer oil is located above the piston. The flow of the buffer oil forms damping, and cooperates with the shock-absorbing spring to absorb the impact energy, thereby reducing the vibration of the square plate, the placement seat and the lower die-cutting knife, and at the same time plays a buffering role for the upper die-cutting knife. When the die-cutting is completed, the upper die-cutting knife rises upward, and the square plate rises with the upper die-cutting knife under the elastic force of the shock-absorbing spring. During this process, the piston will also move upward, so that the square plate, the placement seat and the lower die-cutting knife return to their original position.
