Description

Technical Field

[0001] This utility model relates to the technical field of door frame production equipment, and in particular to a device for automatically attaching expansion seals during the door frame covering process. Background Technology

[0002] Currently, with the increasing demands for building safety and fire resistance, fire doors, as crucial fire protection facilities, are gradually gaining widespread attention and popularity. Among them, wooden fire doors, due to their excellent thermal insulation and decorative effects, are increasingly being used in high-rise residential and commercial buildings. However, existing production and processing methods for wooden fire door frames still present the following problems: 1. To improve fire resistance, currently produced wooden fire door frames generally use high-density organic wood combined with inorganic fire-retardant materials. However, this results in excessively heavy overall weight of the door frame, affecting the difficulty of handling; 2. Traditional production methods typically involve employees manually attaching fire-resistant expansion seals. In actual operation, the door frame needs to be moved multiple times to complete the application of the seal, which not only increases the labor cost of the production line, but also significantly reduces production efficiency. In addition, manual operation is prone to inaccurate bonding position or loose seal, affecting the consistency of product quality. 3. Most of the existing fireproof expansion seals are designed with adhesive backing, which requires manual removal of the release paper before use. This operation is time-consuming and complicated, and the resulting release paper waste is difficult to handle or recycle quickly, which can easily lead to a messy production environment, affecting the cleanliness of the workshop and the convenience of subsequent operations.

Figure 1-5As shown, the system includes a door frame conveying module 1, an expansion seal bonding module 3, and a core paper winding module 4. A coating machine is located at the top of the door frame conveying module 1 and the expansion seal bonding module 3. Several coating machine conveyor wheels 101 are rotatably connected to the middle of the coating machine. A door frame 2 is conveyed on the top of the coating machine conveyor wheels 101. Support components are located on both sides of the coating machine, and door frame conveyor wheels 102 are located at the side ends of the support components and the bonding area between the support components and the door frame 2. The door frame 2 includes a door frame without a seal and a door frame with a seal 407. A door frame seal groove is located at the top of the door frame 2. The core paper winding module 4 is fixed to the top of the expansion seal bonding module 3, and the core paper is wound... The roll module 4 is rotatably connected to a fixed shaft 404. The bottom of the core paper winding module 4 is provided with a core paper winding module pressure roller 406 rotatably connected to the top of the support assembly. The core paper winding module pressure roller 406 is tangent to the top surface of the door frame 2. The door frame conveying module 1 is used to accurately position and convey the door frame without sealing to the sealing station. The expansion sealing module 3 realizes the automatic cutting, peeling of core paper 402, application and compaction of sealing 401. The core paper winding module 4 adopts an active drive mode, and the peeled core paper 402 is concentrated and wound up through an automated system to ensure the cleanliness of the production line and facilitate subsequent waste disposal.

[0026] like Figure 3 and Figure 4 As shown, the bottom of the expansion seal bonding module 3 is equipped with an expansion seal bonding module motor 301. The rotor of the expansion seal bonding module motor 301 is equipped with a belt, and a worm gear 302 is sleeved on the other side of the belt. The worm gear 302 meshes with a worm wheel, and the worm wheel is fixedly connected to a drive shaft. One end of the drive shaft is fixedly connected to the coating machine conveyor wheel 101, and the other end of the drive shaft is rotatably connected to one side of the coating machine. The coating machine conveyor wheel 101 includes two conveyor wheels, and a shaft is fixedly connected between the two conveyor wheels. A support rod is rotatably connected to the center of the shaft.

[0027] The expansion seal bonding module 3 transmits power to the worm gear 302 via a belt driven by the motor 301. The gear on the worm gear drives the worm wheel on the wrapping machine, which in turn drives the conveyor wheel 101 of the wrapping machine to transport the door frame 2 to the expansion seal bonding module 3. The seal 401 is then automatically bonded into the door frame seal groove by the bonding device. The pressure roller 303 has an adjustable pressure function, and by adjusting the position of the pressure roller 303, the seal 401 is pressed firmly into the door frame seal groove.

[0034] Step 1: Place the door frame 2 to be processed into the door frame conveying module 1. After detection by the sensor, it will be automatically conveyed to the covering station and the surface will be covered.

[0035] Step 2: After the covering is completed, the door frame 2 is directly conveyed to the expansion sealing component bonding module 3;

[0036] Step 3: In the expansion seal bonding module 3, after the seal 401 is cut by the seal conveying unit, the core paper 402 is peeled off and attached to the surface of the door frame 2.

[0037] Step 4: Press the sealing element 401 firmly by using the expansion sealing element bonding module pressure roller 303 and the core paper winding module pressure roller 406 to ensure a firm bond;
