Description

Technical Field

[0001] This utility model relates to the field of laminator technology, and in particular to a top cover lifting device for an independent multilayer laminator. Background Technology

[0002] Independent multi-layer laminators are widely used equipment in lamination production processes. During operation, the multi-layer loading mechanism of the laminator needs to perform periodic lifting and lowering movements to load and unload materials or perform equipment maintenance.

[0003] Existing lifting devices typically employ multiple lifting points (such as hydraulic cylinders or lead screws) distributed below or at the four corners of a multi-layer upper box mechanism, achieving lifting through the combined action of multiple power sources.

[0004] However, due to the significant weight and volume of the multi-layer upper box mechanism, relying solely on multiple lifting points for synchronous control during the lifting process is far from sufficient. On one hand, minute motion differences can easily arise between multiple lifting power sources, leading to asynchronous lifting and tilting of the upper box mechanism. On the other hand, the lack of an effective and reliable guiding structure makes the upper box mechanism susceptible to lateral force interference during lifting, resulting in swaying and deviation.

[0005] This asynchronous lifting and swaying during the lifting process not only seriously affects the smoothness and stability of the equipment operation, but also causes jamming between the upper box mechanism and the support frame, and even damages the equipment, reducing production efficiency and equipment reliability.

[0006] Therefore, this utility model proposes a top cover lifting device for an independent multi-layer laminator to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology of the top cover lifting device of the independent multi-layer laminator, such as the difficulty in ensuring the synchronization of multi-point lifting during the lifting of the multi-layer upper box mechanism and the lack of an effective guiding structure, which leads to easy deviation and shaking and low reliability, this utility model aims to provide a top cover lifting device for the independent multi-layer laminator with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a top cover lifting device for an independent multi-layer laminator, including: a support frame, a multi-layer upper box mechanism, a lifting mechanism, and a guiding mechanism.

[0009] The lifting mechanism includes a drive assembly, a cylinder connecting rod, and a lifting rod. The drive assembly includes a hydraulic cylinder and a drive rod. The drive rod is telescopically mounted in the hydraulic cylinder and drives the cylinder connecting rod. The cylinder connecting rod and the lifting rod are connected in sections. The lifting rod carries the multi-layer upper box mechanism. The lifting mechanism is used to drive the multi-layer upper box mechanism to rise and fall.

[0010] The guiding mechanism is connected to the multi-layer upper box mechanism and provides guidance during the lifting and lowering of the multi-layer upper box mechanism. The guiding mechanism includes a support block, a support plate, a guide frame, and guide wheels. The support block is fixed to the left and right sides of the top of the multi-layer upper box mechanism, the support plate is fixedly connected to the support block, the guide frame is fixed to the support plate, and the guide wheels are rotatably installed inside the guide frame. The guide wheels can roll along the inner wall of the support frame.

[0011] The lifting mechanism and the guiding mechanism work together, with the lifting mechanism providing synchronous and stable vertical lifting power and the guiding mechanism providing precise rolling limit and guiding function, thereby ensuring that the multi-layer upper box mechanism can maintain high synchronization and good stability during the lifting process.

[0012] Preferably, the lifting mechanism further includes a cylinder locking ring, which is sleeved on the cylinder connecting rod and used to fix the cylinder connecting rod after the position is adjusted, so as to ensure precise locking of the lifting stroke.

[0013] Preferably, the drive rod is connected to the hydraulic cylinder connecting rod via an external thread. This threaded connection method is characterized by convenient installation and reliable connection.

[0014] Preferably, the hydraulic cylinder connecting rod and the lifting rod are connected in sections using an internal and external thread structure. This structure facilitates multi-segment length adjustment and assembly of the lifting rod to adapt to laminators with different numbers of layers.

[0015] Preferably, each connection point between the hydraulic cylinder connecting rod and the lifting rod is provided with a metal washer and a retaining ring. The retaining ring is used to lock the connection point from top to bottom to prevent the upper box mechanism from sliding unexpectedly on the lifting rod, thereby further improving positioning accuracy and safety.

[0016] Preferably, the guide frame has a groove inside, and the guide wheel is installed inside the guide frame by bolts passing through the groove. The bolts are used to adjust and fix the position of the guide wheel, thereby allowing precise adjustment of the guide clearance during the equipment commissioning phase.

[0017] Preferably, the lifting mechanism comprises four sets, which are respectively arranged at the four corners of the support frame. The driving component is driven by a synchronous motor. This symmetrical layout at the four corners and the use of synchronous drive maximizes the synchronization of the lifting of the multi-layer upper box mechanism and avoids tilting caused by uneven load.

[0018] Preferably, the guide frame is welded from a thicker steel plate to provide sufficient strength and rigidity, ensuring that it will not deform significantly when subjected to lateral guiding forces, thereby improving the reliability of the guide.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problems of poor synchronization and lack of effective guidance in the existing multi-layer upper box mechanism during lifting and lowering, which leads to easy deviation, shaking and poor stability. It achieves the technical effect of smooth lifting, high synchronization, accurate guidance and good stability.

[0020] 2. This utility model achieves the technical effect of reliable structural connection, convenient adjustment, and firm fixation by connecting the driving rod of the lifting mechanism and the oil cylinder connecting rod through external thread and fixing them with oil cylinder locking ring. At the same time, the oil cylinder connecting rod and the lifting rod are connected in sections with internal and external thread structure and metal washers and fixing rings are set for upper and lower locking.

[0021] 3. This utility model installs the guide wheel of the guide mechanism by bolting it through a groove opened inside the guide frame, making the position of the guide wheel adjustable. This solves the problem of fixed gaps and difficulty in adjustment of the guide structure in the prior art, and achieves the technical effect of convenient adjustment and strong adaptability of the guide mechanism.

[0024] Example: Reference Figures 1 to 4This utility model provides a lifting device for the top cover of an independent multi-layer laminator, which aims to solve the problems in the prior art where the synchronization of multi-point lifting during the lifting process of the multi-layer upper box mechanism is difficult to guarantee, and the lack of an effective guiding structure leads to easy deviation and shaking during lifting, resulting in poor stability.

[0025] like Figure 1 As shown, a lifting device for the top cover of an independent multi-layer laminator includes a support frame 1, which provides basic support for the multi-layer upper box mechanism located inside the support frame 1. It also includes a lifting mechanism 2 and a guiding mechanism 3. The lifting mechanism 2 is mounted on the support frame 1. Specifically, the lifting mechanism 2 includes four sets, which are respectively located at the four corners of the support frame 1. The lifting mechanism 2 is driven by a synchronous motor and is used to drive the multi-layer upper box mechanism to achieve synchronous lifting and lowering movements. The guiding mechanism 3 is connected to the multi-layer upper box mechanism and provides guidance when the multi-layer upper box mechanism is lifted and lowered, ensuring the stability of the lifting process and preventing deviation.

[0026] The drive rod 212 is connected to the cylinder connecting rod 23 via an external thread. The lifting mechanism 2 also includes a cylinder locking ring 22, which is sleeved on the cylinder connecting rod 23. When the cylinder connecting rod 23 is adjusted to a suitable position, the cylinder connecting rod 23 is fixed by the cylinder locking ring 22, thereby achieving a reliable connection and position adjustment between the drive rod 212 and the cylinder connecting rod 23.

[0027] The hydraulic cylinder connecting rod 23 and the lifting rod 24 are connected in sections with internal and external threads, which facilitates the assembly and length adjustment of the lifting rod 24. Each section of the hydraulic cylinder connecting rod 23 and the lifting rod 24 is equipped with a metal washer 25 and a fixing ring 26. When the position of each upper box mechanism is adjusted, the connection is locked by the fixing ring 26 to prevent the upper box mechanism from sliding on the connecting rod 23.

[0028] The guide frame 33 is welded from a thick steel plate. A groove is provided inside the guide frame 33. The guide wheel 34 is installed inside the guide frame 33 by passing through the groove with bolts 35. The guide wheel 34 can slide inside the guide frame 33 and is fixed in position by bolts 35. The relative position between the guide wheel 34 and the guide frame 33 can be changed by adjusting the bolts 35, thereby enhancing the structural strength and adjustment flexibility of the guide mechanism 3.

[0029] The lifting mechanism 2 is configured as four sets, which are respectively installed at the four corners of the device. The drive component 21 is driven by a synchronous motor, which works with the external hydraulic station and hydraulic pipeline to achieve power output. The drive rod 212 of the four sets of lifting mechanisms 2 drives the oil cylinder connecting rod 23 and the lifting rod 24 to perform synchronous lifting and lowering movements, thereby ensuring the overall lifting and lowering is stable and synchronous.

[0030] The working principle is as follows: Before operation, the relative position of the guide wheel 34 and the guide frame 33 is changed and fixed by adjusting the bolt 35 passing through the guide frame 33 groove. At the same time, after the drive rod 212 and the cylinder connecting rod 23 are connected to the appropriate position through the external thread, they are fixed by the cylinder locking ring 22. The cylinder connecting rod 23 and the lifting rod 24 are connected in sections with internal and external thread structure, and the metal washer 25 set at the connection part is locked by the fixing ring 26 to fix the position of the multi-layer upper box mechanism.

[0031] During operation, the hydraulic cylinders 211 in the four sets of drive components 21 are started by the synchronous motor. The hydraulic cylinders 211 drive the drive rods 212 to move. The drive rods 212 drive the cylinder connecting rods 23 and the lifting rods 24 to move synchronously, thereby realizing the synchronous lifting of the multi-layer upper box mechanism. As the multi-layer upper box mechanism is raised and lowered, the support block 32, support plate 31 and guide frame 33 fixed on the multi-layer upper box mechanism move accordingly. The guide wheel 34 inside the guide frame 33 rolls along the inside of the support frame 1 to provide guidance for the multi-layer upper box mechanism, ensure its stability during the raising and lowering process and prevent deviation.

[0032] By providing synchronous power through the lifting mechanism 2 and stable guidance through the guiding mechanism 3, the problem of poor synchronization and easy swaying and deviation during the lifting and lowering of multi-layer upper box mechanisms in the prior art is solved.
