Description

Technical Field

[0001] This utility model relates to the field of protective technology for laminating machines, and in particular to a protective mechanism for a laminating machine. Background Technology

[0002] Laminating machines can be broadly classified into two categories: instant-coating laminating machines and pre-coating laminating machines. They are specialized equipment used for laminating paper, boards, and other materials. The laminating process involves pressing the materials together using rubber rollers and heated rollers to form a paper-plastic composite product. However, existing laminating machines, during high-speed lamination, suffer from the following drawbacks due to the rapid rotation of components such as the film feeding roller and the hot press roller, and the lack of protective mechanisms:

[0003] 1. Safety hazard: When an operator's hand or tools accidentally enter the film-coating area, there is a lack of a rapid response protection mechanism, which can easily lead to mechanical pinching accidents.

[0004] 2. Foreign object interference: Foreign objects entering the coating area can easily cause uneven coating or equipment jamming, requiring machine shutdown for cleaning and reducing production efficiency.

[0005] Therefore, a protective mechanism for a laminating machine needs to be designed. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective mechanism for a laminating machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A protective mechanism for a laminating machine includes a frame and a laminating machine body mounted on the frame. Two vertical plates are fixed to the upper end of the frame, and the two vertical plates are respectively located on both sides of the laminating machine body. A horizontal plate is fixedly connected between the two vertical plates. A protective cover is provided below the horizontal plate. A lifting cylinder is installed at the upper end of the horizontal plate. The telescopic end of the lifting cylinder passes downward through the horizontal plate and is fixedly connected to the top of the protective cover. Two safety light curtain mechanisms are provided between the two vertical plates, and the two safety light curtain mechanisms are respectively located on both sides of the laminating machine body.

[0009] As a further improvement of this utility model, the safety light curtain mechanism includes a light emitter and a light receiver, which are respectively installed on the side walls of two vertical plates.

[0010] As a further improvement of this utility model, each of the two vertical plates is provided with a sliding groove on its side wall, and a slider is fixedly connected to each of the opposite side walls of the protective cover, with the two sliders respectively slidably connected inside the two sliding grooves.

[0011] As a further improvement of this utility model, a rubber block is fixed to the lower end of the slider.

[0012] As a further improvement of this utility model, a locking cylinder is installed on the side wall of the vertical plate, and a locking rod is fixedly connected to the telescopic end of the locking cylinder. The locking rod passes through the side wall of the vertical plate and extends into the interior of the slide groove. A locking hole that cooperates with the locking rod is provided on the side wall of the slider.

[0013] As a further improvement of this utility model, the protective cover is made of polycarbonate material.

[0014] The beneficial effects of this utility model are:

[0015] By utilizing a safety light curtain mechanism, it is possible to monitor the intrusion of foreign objects or human body parts in real time. When the intrusion of foreign objects or human body parts is detected, the lifting cylinder is activated and extended, and the protective cover is lowered and placed on the outside of the laminating machine body, thus solving the problem of equipment damage and safety hazards caused by operators accidentally touching or foreign objects entering during the laminating operation.

[0016] When the protective cover descends to provide protection, the locking cylinder extends and drives the locking rod to insert into the locking hole on the slider, locking the slider in place. This ensures that the protective cover is fixed in position after it is closed, maintaining the stability of the protective state. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A protective mechanism for a laminating machine includes a frame 1 and a laminating machine body 2 mounted on the frame 1. Two vertical plates 3 are fixed to the upper end of the frame 1, and the two vertical plates 3 are respectively located on both sides of the laminating machine body 2. A horizontal plate 6 is fixedly connected between the two vertical plates 3. A protective cover 8 is provided below the horizontal plate 6. The protective cover 8 is made of polycarbonate, which is a transparent and high-temperature resistant material, so that the status of the laminating machine body 2 can be observed through the protective cover 8. A lifting cylinder 7 is installed at the upper end of the horizontal plate 6. The extension end of the lifting cylinder 7 passes through the horizontal plate 6 downward and is fixedly connected to the top of the protective cover 8. Two safety light curtain mechanisms are provided between the two vertical plates 3, and the two safety light curtain mechanisms are respectively located on both sides of the laminating machine body 2.

[0024] In this utility model, the safety light curtain mechanism includes a light emitter 4 and a light receiver 5. The light emitter 4 and the light receiver 5 are respectively installed on the side walls of two vertical plates 3. Light is emitted by the light emitter 4 and received by the light receiver 5. When the light is blocked by a foreign object or a human body part, the intrusion of the foreign object or human body part can be monitored in real time.

[0025] Both vertical plates 3 have grooves 9 on their side walls, and sliders 10 are fixedly connected to the opposite side walls of the protective cover 8. The two sliders 10 are slidably connected inside the two grooves 9. A rubber block 11 is fixed to the lower end of the slider 10. The rubber block 11 can buffer the impact force of the slider 10 when it slides down inside the groove 9, effectively protecting the slider 10. Furthermore, a locking cylinder 13 is installed on the side wall of the vertical plate 3. A locking rod 14 is fixedly connected to the telescopic end of the locking cylinder 13. The locking rod 14 passes through the side wall of the vertical plate 3 and extends into the groove 9. The side wall of the slider 10 is provided with a locking hole 12 that cooperates with the locking rod 14.

[0026] When this utility model is in use, the safety light curtain mechanism can monitor the intrusion of foreign objects or human body parts in real time. When the intrusion of foreign objects or human body parts is detected, the lifting cylinder 7 starts to extend and drives the protective cover 8 to descend and cover the outside of the laminating machine body 2. The protective cover 8 provides protection and solves the problem of equipment damage and safety hazards caused by accidental contact by the operator's limbs or the entry of foreign objects during the laminating operation. Then, the locking cylinder 13 starts to extend and drives the locking rod 14 to insert into the locking hole 12 on the slider 10, locking the slider 10. This ensures that the position of the protective cover 8 is fixed after it is closed, and maintains the stability of the protective state.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
