Technical Field

[0001] This utility model relates to the field of composite film production technology, and in particular to a tooling for disassembling and assembling composite pressure rollers on a laminating machine. Background Technology

[0002] As a key piece of equipment in modern packaging, printing, and composite material production, laminating machines are constantly improving in terms of automation and production efficiency with the development of the industry. In the lamination process of composite films, the laminating roller, as a core component, is prone to wear due to friction caused by long-term high-pressure operation, requiring regular replacement to ensure product quality and equipment stability.

[0003] The existing technology for disassembling and installing composite pressure rollers has the following shortcomings:

[0004] 1. Structural design issues: Due to the heavy weight of the composite pressure roller and the limited installation position on the laminating machine, existing equipment generally relies on manual handling of the composite pressure roller, usually requiring 3 adult operators and a stacker forklift to complete the assembly and disassembly of the composite pressure roller entirely by manpower.

[0005] 2. Low operating efficiency: Due to the lack of specialized equipment, the disassembly or installation of the composite pressure roller is complicated and usually takes 2 hours, which seriously affects the production cycle and increases downtime costs.

[0006] 3. Significant safety hazards exist. During handling, due to the large weight of the composite pressure roller and the narrow operating space, safety accidents such as squeezing and crushing injuries to operators are very likely to occur, posing a high operational risk. Therefore, improvements are needed. Utility Model Content

[0007] The main technical problem solved by this utility model is to provide a tooling for disassembling and assembling composite pressure rollers on a laminating machine, with optimized structural design to assist in the quick and safe disassembly and assembly of composite pressure rollers.

[0008] To solve the above-mentioned technical problems, the present invention provides a tooling for disassembling and assembling composite pressure rollers on a laminating machine, comprising: a bracket, a pin, and a shaft support. The bottom of the bracket is provided with a slot corresponding to the fork teeth of a stacker. The bottom of the slot is provided with a baffle. The baffle is provided with a positioning hole corresponding to the pin. The pin vertically penetrates the fork teeth and extends into the positioning hole. The top two sides of the bracket are provided with forward-extending support arms, and the shaft support is located at the front end of the support arms.

[0009] In a preferred embodiment of this utility model, the pin adopts a stepped shaft structure.

[0010] In a preferred embodiment of the present invention, the composite pressure roller is provided with journals at both ends, and the top surface of the shaft support is provided with a positioning groove corresponding to the journal.

[0011] In a preferred embodiment of this utility model, the positioning groove adopts an arc structure.

[0012] In a preferred embodiment of the present invention, a pin mounting plate is further included. The pin mounting plate is detachably disposed above the slot, and the pin mounting plate is provided with mounting holes corresponding to the pins.

[0013] In a preferred embodiment of this utility model, a handle is provided on the pin mounting plate.

[0014] The beneficial effects of this utility model are as follows: The tooling for disassembling and assembling composite pressure rollers on a laminating machine, as indicated by this utility model, allows the fork teeth of the stacker to be inserted into the corresponding slots and locked by pins to ensure the safety of the operation process. The stacker moves the shaft support to below the journals at both ends of the composite pressure roller, assisting in the rapid disassembly and assembly of the composite pressure roller. This improves the adaptability to the installation space in the laminating machine. A single person can complete the disassembly or assembly within 15 minutes, significantly improving work efficiency and safety, reducing labor intensity and downtime losses, and eliminating the safety hazards caused by traditional manual handling.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 and Figure 2 The embodiments of this utility model include:

[0020] like Figure 1 and Figure 2 The tooling shown is used for disassembling and assembling the composite pressure roller on the laminating machine. It works in conjunction with a stacker trolley to disassemble and assemble the composite pressure roller 5. The tooling includes: a bracket 1, a pin 4, a shaft support 3, and a pin mounting plate 6. The bottom of the bracket 1 is provided with slots 11 corresponding to the forks 8 of the stacker trolley, guiding the forks of the stacker trolley to quickly insert into the corresponding slots 11. The bracket 1 adopts a square frame structure welded from angle steel and square tubing, which is lightweight and has high structural strength.

[0021] A baffle 12 is provided at the bottom of the slot 11. The baffle 12 is provided with a positioning hole 13 corresponding to the pin 4. The pin 4 vertically passes through the fork tooth 8 and extends into the positioning hole 13 to limit the position of the fork tooth 8, improve the stability and safety of the bracket 1 on the fork tooth 8, and avoid the problem of detachment.

[0022] To facilitate the disassembly of the pin 4, in this embodiment, the pin mounting plate 6 is detachably disposed above the slot 11, and the pin mounting plate 6 is provided with mounting holes 7 corresponding to the pin 4, such as... Figure 2 As shown, this facilitates the installation of the pin 4 and the removal of the pin mounting plate 6.

[0023] In this embodiment, the pin 4 adopts a stepped shaft structure, which can axially limit the pin 4 in the mounting hole 7 and prevent the pin 4 from falling off. The pin mounting plate 5 is provided with a handle 14. By holding the handle 14, the pin mounting plate 5 and the pin 4 can be moved simultaneously, thereby improving the convenience of assembling and disassembling the pin 4.

[0024] like Figure 1 As shown, the bracket 1 has forward-extending support arms 2 on both sides of its top, and the shaft support 3 is located at the front end of the support arm 2. The support arm 2 is made of square tubing, and the shaft support 3 is fixed to the front end of the support arm 2 with bolts. The structure is stable and easy to replace.

[0025] A journal 10 is provided at both ends of the composite pressure roller 5. A positioning groove 9 corresponding to the journal 10 is provided in the concave top surface of the bearing support 3. In this embodiment, the positioning groove 9 adopts an arc structure, which has a high degree of fit with the bearing on the journal 10, improves the stability during disassembly and assembly, and avoids tilting and falling during transportation.

[0026] The process of disassembling the laminating roller on the laminating machine:

[0027] First, insert the forks of the stacker truck into the corresponding slots 11 and lock them with the pins 4 to ensure safety during operation.

[0028] The stacker truck moves the bearing support 3 to below the journals 10 at both ends of the composite pressure roller to form a reliable support and prevent the pressure roller 5 from falling.

[0029] After opening the bearing cover corresponding to journal 10 in the laminating machine, the stacker is jogged to raise the bearing support 3, so that the bearing in journal 10 gradually separates from the bearing seat. The whole process is smooth and controllable, avoiding impact damage.

[0030] Once the bearing has risen to the point of being completely detached from the bearing housing, the stacker can be directly removed, and the composite pressure roller 5 can be moved out of the equipment as a whole, achieving rapid disassembly, enabling single-person operation, significantly reducing labor intensity, and improving safety and work efficiency.

[0031] In summary, the tooling for disassembling and assembling the composite pressure roller on the laminating machine, as indicated by this utility model, has undergone structural optimization design, has good compactness, and improves adaptability to the installation space in the laminating machine, enabling rapid disassembly and assembly of the composite pressure roller on the laminating machine.
