Description

Technical Field

[0001] This utility model belongs to the technical field of door panel processing, specifically a door panel coating machine with a protective mechanism. Background Technology

[0002] In the door panel processing industry, lamination technology can effectively improve the aesthetics, moisture resistance, and durability of door panels, thus door panel laminating machines have been widely used. Traditional door panel laminating machines are often designed with an emphasis on the basic lamination function, paying insufficient attention to safety protection and ease of operation during the production process.

[0003] On the one hand, during the cutting process, the high-speed cutting blades are exposed, and if operators are not careful and get close, accidents can easily occur, posing a huge threat to the personal safety of workers. Moreover, due to the lack of accurate protective sensing devices, once the cutting action is triggered by misoperation, the consequences are unimaginable.

[0004] On the other hand, there are also defects in the placement and fixing of door panels before lamination. If the door panels cannot be accurately positioned and placed securely, displacement deviations are likely to occur in subsequent lamination, cutting and other processes, resulting in uneven lamination, inaccurate cutting dimensions, increased scrap rate and increased production costs.

[0005] In conclusion, traditional door panel laminating machines urgently need a complete set of protection and optimization mechanisms to meet the stringent requirements of modern production for safety, efficiency, and high precision. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a door panel laminating machine with a protective mechanism, which solves the technical problem that in the cutting process, the high-speed rotating cutting blades are exposed, and if the operator is not careful and gets close, an accidental injury is very likely to occur, which poses a great threat to the personal safety of the workers.

[0007] The present invention adopts the following solution: a door panel laminating machine with a protective mechanism, comprising a laminating machine body, characterized in that the laminating machine body includes a laminating section and a film loading section, a placement plate is slidably connected to the laminating machine body, the placement plate slides between the laminating section and the film loading section, the placement plate is driven by a first power device, a door panel punch is provided on the placement plate, a film loading assembly and a film cutting assembly are provided on the laminating machine body, the film cutting assembly includes a film cutting bracket fixedly connected to the laminating machine body, a cutting seat is slidably connected to the film cutting bracket, a cutting blade is detachably connected to the cutting seat, the cutting seat is driven by a second power device, an auxiliary bracket is provided on the cutting seat, and a light curtain sensor corresponding to the cutting blade is provided on the auxiliary bracket.

[0008] Preferably, the first power device includes a first lead screw rotatably connected to the laminating machine body, the first lead screw being threadedly connected to the placement plate, and a first electric motor fixedly connected to the laminating machine body, the lead screw being driven by the first electric motor.

[0009] Preferably, the second power device includes a second lead screw rotatably connected to the film cutting bracket, the second lead screw being threadedly connected to the cutting seat, a second motor being fixedly connected to the film cutting bracket, and the second lead screw being driven by the second motor.

[0010] Preferably, the film loading assembly includes two sets of fixed brackets, the two sets of fixed brackets are slidably connected to movable brackets, and the two sets of movable brackets are rotatably connected to a film roller. One set of fixed brackets is threadedly connected to an adjusting screw, one end of which is rotatably connected to the movable bracket, and the other end is fixedly connected to an adjusting handle.

[0011] Preferably, the film cutting bracket is rotatably connected to a plurality of first auxiliary rollers, the fixed bracket is provided with a film outlet, and the fixed bracket is slidably connected to two sets of second auxiliary rollers corresponding to the film outlet, the two sets of second auxiliary rollers being symmetrically arranged with respect to the center of the film outlet.

[0012] Preferably, the placement plate has a placement groove, a pressure plate is slidably connected in the placement groove, and a locking screw is threadedly connected to the placement plate. One end of the locking screw is rotatably connected to the pressure plate, and the other end is connected to a locking handle. Beneficial effects

[0013] I. Excellent safety protection performance: By setting up a light curtain sensor on the cutting seat corresponding to the cutting blade, a sensitive and reliable safety barrier is built. Once the operator's body part approaches the dangerous cutting area, the light curtain sensor instantly detects the change in light signal and immediately transmits a signal to the control system, causing the cutting seat to stop moving and simultaneously issuing an audible and visual alarm, effectively avoiding accidental injury accidents and creating a safe and worry-free working environment for the operator.

[0014] II. Convenient and Efficient Film Loading Experience: The film loading assembly features two sets of fixed supports paired with slidingly connected movable supports and a rotatable membrane roller, making membrane installation more flexible. Using adjusting screws and handles, operators can easily adjust the spacing of the movable supports according to the width of the membrane, ensuring appropriate membrane tension and stable installation. Simultaneously, the membrane outlet and symmetrically arranged second auxiliary rollers guide the membrane out smoothly and steadily, reducing wrinkles and jamming, significantly improving loading efficiency and reducing the error rate.

[0015] 3. Precise and stable door panel positioning: Driven by the first power unit, the placement plate can slide precisely between the film coating section and the film loading section. The door panel punch set on it works in conjunction with the placement groove and the pressure plate. After the door panel is placed in the placement groove, the locking screw is rotated and the pressure plate tightly presses the door panel. Combined with the limiting of the door panel punch, it effectively prevents the door panel from shifting or shaking during processing, providing a precise positioning basis for subsequent film coating, cutting and other processes, ensuring film coating quality and cutting accuracy, and reducing scrap rate.

[0016] IV. Precise Cutting Control: The second power unit drives the cutting seat to slide along the film cutting support. The combination of a high-precision lead screw and motor ensures smooth movement and accurate positioning of the cutting seat. Operators can flexibly control the position of the cutting blade according to the door panel size and film cutting requirements. With the replaceable cutting blade design, it meets diverse cutting needs, improves cutting quality and efficiency, and adapts to different production tasks. Attached Figure Description
