Description

Technical Field

[0001] This utility model relates to the field of fire blanket processing technology, specifically a hot pressing device for fire blanket production. Background Technology

[0002] Fire blankets, also known as fire-extinguishing blankets, fire-fighting blankets, flame-retardant blankets, or escape blankets, are fabrics woven from materials such as fiberglass through special treatment. They serve to isolate heat sources and flames. Fire blankets possess the characteristics of ordinary fibers, such as softness, elasticity, and a certain tensile strength, while also exhibiting high-temperature resistance and corrosion resistance not found in ordinary fibers. As a fire-resistant and heat-insulating material, they have been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace, and other industrial sectors.

[0003] Fire blankets are typically manufactured by layering multiple layers of flame-retardant materials. The processing involves impregnating the flame-retardant materials with adhesive, followed by hot pressing, cooling, and other steps to complete the fabrication. Existing hot pressing equipment uses a heating plate to press and heat the flame-retardant material layers, resulting in long heating times and low production efficiency. During the hot pressing process, the conveyor belt must remain stationary, pausing its transport of the flame-retardant material layers. Conversely, when the conveyor belt rotates to transport the flame-retardant material, the heating plate must remain raised to ensure smooth transport. Therefore, ensuring the coordinated adaptation of the conveyor belt rotation and heating plate movement in existing hot pressing equipment is crucial for improving the hot pressing efficiency of fire blankets. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a hot pressing device for fire blanket production, thereby solving the problems of low production efficiency and poor coordination between the rotation of the conveyor belt and the lifting of the heating plate in existing fire blanket hot pressing production.

An I-shaped pressing slide is slidably mounted on the guide plate. One end of the pressing slide has a drive groove, and the drive column is engaged and slidably mounted in the drive groove. The other end of the pressing slide is correspondingly mounted to the button switch.

[0016] Furthermore, a heat collection box is provided above the conveyor belt, the lifting cylinder is fixedly installed on the inner top wall of the heat collection box, a guide cylinder is provided on the inner top wall of the heat collection box, a guide column is slidably provided inside the guide cylinder, and the guide column is connected to the heating plate.

[0018] Furthermore, the auxiliary processing mechanism includes a mounting frame and an auxiliary processing roller. The two ends of the auxiliary processing roller are rotatably mounted on the mounting frame via a rotating shaft. Both the auxiliary processing roller and the rotating shaft are hollow structures.

[0019] Furthermore, an air pump is provided on the side wall of the heat collection box. The inlet pipe of the air pump extends through the side wall of the heat collection box into the heat collection box.

[0031] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a hot pressing device for fire blanket production, comprising:

[0034] Conveyor belt 1, with an external intermittent rotation mechanism connected to conveyor belt 1, which drives conveyor belt 1 to rotate intermittently;

[0035] A button control mechanism is connected to an intermittent rotation mechanism.

[0036] Push button switch 2 is configured in correspondence with push button control mechanism, which is used to control the open and closed state of push button switch 2.

[0037] Lifting cylinder 3 is electrically connected to button switch 2. Button switch 2 controls the lifting action of lifting cylinder 3. When button switch 2 is pressed, lifting cylinder 3 extends. When button switch 2 is released, lifting cylinder 3 retracts.

[0038] Heating plate 4 is connected to the free end of lifting cylinder 3. The extension and retraction of lifting cylinder 3 drives heating plate 4 to rise and fall.

[0039] When in use, the lifting cylinder 3 is in a retracted state when the conveyor belt 1 rotates and transports the fireproof blanket. At this time, the heating plate 4 is away from the fireproof blanket, so that the conveyor belt 1 can transport the fireproof blanket smoothly. When the conveyor belt 1 stops rotating, the lifting cylinder 3 is in an extended state. At this time, the heating plate 4 is driven to press onto the fireproof blanket to perform hot pressing processing on the fireproof blanket.

[0040] Specifically, see Figure 1 , Figure 2 and Figure 5 In this embodiment, the conveyor belt 1 includes a support frame, a drive roller, a driven roller, and a belt body. The drive roller and the driven roller are rotatably mounted on the support frame, and the two ends of the belt body are sleeved on the drive roller and the driven roller. The belt body is driven to rotate by the cooperation of the drive roller and the driven roller, thereby realizing the conveying of the stacked fireproof blankets.

[0041] The intermittent rotation mechanism includes an intermittent rotation motor 5, an incomplete gear 6 fixedly mounted on the output shaft of the intermittent rotation motor 5, a drive shaft rotatably mounted on the support frame, the drive shaft being connected to the drive roller, a drive gear 7 fixedly mounted on the drive shaft, the drive gear 7 intermittently meshing with the incomplete gear 6, and as the incomplete gear 6 rotates, it drives the drive gear 7 to rotate intermittently, thereby driving the conveyor belt 1 to rotate intermittently, thus realizing the intermittent feeding of the fireproof blanket.

[0042] It should be noted that the number of serrations on the incomplete gear 6 is equal to the number of serrations on the drive gear 7. Each rotation of the incomplete gear 6 causes the drive gear 7 to rotate one revolution.

[0043] Specifically, see Figure 1 and Figure 2 In this embodiment, a limiting boss 8 is fixedly provided on the incomplete gear 6, and a limiting baffle 9 is fixedly provided on the drive shaft. An arc-shaped groove 10 is provided on the limiting baffle 9. The arc-shaped groove 10 is adapted to the curvature of the limiting boss 8. When the non-gear arc surface of the incomplete gear 6 rotates to be close to the drive gear 7, the limiting boss 8 just fits with the arc-shaped groove 10, ensuring the stability of the relative rotation between the incomplete gear 6 and the drive gear 7.

[0044] Specifically, see Figure 1 and Figure 2 In this embodiment, a protruding plate 11 is fixedly provided on the support frame, a mounting plate 12 is provided on the protruding plate 11, a push-button switch 2 is provided on the mounting plate 12, and a guide plate 13 is provided on the mounting plate 12.

[0045] The button control mechanism includes a disc 14, which is fixed on the drive shaft. A drive column 15 is eccentrically mounted on the disc 14. An I-shaped pressing slide plate 16 is slidably mounted on the guide plate 13. One end of the pressing slide plate 16 has a drive groove 17, and the drive column 15 is engaged and slidably mounted in the drive groove 17. The other end of the pressing slide plate 16 is correspondingly mounted to the button switch 2. When the drive shaft rotates, the driving column 15 drives the pressing slide plate 16 to slide along the guide plate 13. When the pressing slide plate 16 is driven to press the button switch 2, the lifting cylinder 3 extends, driving the heating plate 4 to press onto the fireproof blanket, thus heat-pressing the fireproof blanket.

[0046] Specifically, see Figure 1 , Figure 4 and Figure 5 In this embodiment, a heat collection box 18 is provided above the conveyor belt 1. The lifting cylinder 3 is fixedly installed on the inner top wall of the heat collection box 18. A guide cylinder 19 is provided on the inner top wall of the heat collection box 18. A guide column 20 is slidably provided inside the guide cylinder 19. The guide column 20 is connected to the heating plate 4. The stability of the lifting cylinder 3 driving the heating plate 4 to rise and fall is improved by the cooperation of the guide cylinder 19 and the guide column 20.

[0047] Specifically, see Figure 1 and Figure 4 In this embodiment, auxiliary processing mechanisms are provided on both sides of the heat collection box 18. The auxiliary processing mechanisms include a preheating mechanism 21 and a cooling mechanism 22. The preheating mechanism 21 is located on the front side of the heat collection box 18, and the cooling mechanism 22 is located on the rear side of the heat collection box 18. The preheating mechanism 21 is used to preheat the fireproof blanket before hot pressing to improve the hot pressing efficiency. The cooling mechanism 22 is used to cool the fireproof blanket after hot pressing.

[0048] Specifically, see Figure 1 , Figure 3 and Figure 4 In this embodiment, the auxiliary processing mechanism includes a mounting frame 23 and an auxiliary processing roller 24. The two ends of the auxiliary processing roller 24 are rotatably mounted on the mounting frame 23 via a rotating shaft 25. Both the auxiliary processing roller 24 and the rotating shaft 25 are hollow structures. Through the hollow structure, hot air or coolant is introduced into the auxiliary processing roller 24 to preheat the fireproof blanket or cool it after hot pressing.

[0049] It should be noted that the auxiliary processing roller 24 provided in this embodiment is fixed. If it is necessary to perform hot pressing treatment on fire blankets of different thicknesses, the height of the auxiliary processing roller 24 can be set to adjustable. Specifically, the auxiliary processing roller 24 can be raised and lowered by a cylinder so that the fire blanket passes under the auxiliary processing roller 24 and can be stably pressed onto the fire blanket during the conveying process.

[0050] Specifically, see Figure 1 and Figure 5 In this embodiment, a vacuum pump 26 is provided on the side wall of the heat collection box 18. The inlet pipe of the vacuum pump 26 extends through the side wall of the heat collection box 18 and into the heat collection box 18. The outlet pipe 27 of the vacuum pump 26 is connected to a set of rotating shafts 25 of the preheating mechanism 21. The rotating shafts 25 are rotatably arranged relative to the outlet pipes 27. The other set of rotating shafts 25 of the preheating mechanism 21 is connected to the outside. Under the action of the vacuum pump 26, the hot air in the heat collection box 18 is extracted into the auxiliary processing roller 24 of the preheating mechanism 21. The surface of the fireproof blanket being transported is preheated by the auxiliary processing roller 24.

[0051] Specifically, see Figure 1 and Figure 4 In this embodiment, the rotating shafts 25 at both ends of the auxiliary processing roller 24 of the cooling mechanism 22 are connected to the inlet and outlet of the cooling water circulation pump through water pipes 28, respectively. The water pipes 28 are rotatably connected to the rotating shafts 25. Under the action of the cooling water circulation pump, coolant is input into the auxiliary processing roller 24 of the cooling mechanism 22 to cool the fireproof blanket after hot pressing.

[0052] This embodiment provides a hot pressing device for fire blanket production, the specific working principle of which is as follows:

[0053] (1) First, place the stacked fireproof blankets on the conveyor belt 1 and pass them under the auxiliary processing rollers 24 of the preheating mechanism 21 and the cooling mechanism 22 in sequence. The stacked fireproof blankets are conveyed under the action of the conveyor belt 1.

[0054] (2) Start the intermittent rotating motor 5, which drives the incomplete gear 6 to rotate. When the incomplete gear 6 meshes with the drive gear 7, it drives the drive gear 7 to rotate. The drive gear 7 drives the conveyor belt 1 to rotate through the drive shaft, thereby realizing the conveying of the fireproof blanket. As the incomplete gear 6 rotates, when the incomplete gear 6 rotates to the point where it no longer meshes with the drive gear 7, the incomplete gear 6 no longer drives the drive gear 7 to rotate, and at this time the conveyor belt 1 stops rotating. When the incomplete gear 6 drives the drive gear 7 to rotate, the drive shaft drives the limit baffle 9 and the disc 14 to rotate synchronously with it. During this process:

[0055] ① When the incomplete gear 6 rotates to a state where it is not meshed with the drive gear 7, the limiting baffle 9 rotates with the drive shaft to a state where the arc groove 10 faces the incomplete gear 6 and remains stationary. When the incomplete gear 6 rotates, the limiting boss 8 of the incomplete gear 6 slides against the arc groove 10.

[0056] ② When the incomplete gear 6 rotates to a state where it is not engaged with the drive gear 7, the disc 14, through the cooperation of the drive column 15 and the drive groove 17, drives the pressing slide plate 16 to approach the button switch 2 and presses the button switch 2. The button switch 2 drives the lifting cylinder 3 to extend, and the lifting cylinder 3 drives the pressure plate to press onto the fire blanket, performing heat pressing treatment on the fire blanket. As the incomplete gear 6 rotates, when the incomplete gear 6 rotates to engage with the drive gear 7, under the action of the disc 14, it drives the pressing slide plate 16 away from the button switch 2. The lifting cylinder 3 automatically retracts, driving the heating plate 4 away from the fire blanket, and the conveyor belt 1 can smoothly transport the fire blanket forward.

[0057] (3) The heat generated by the heating plate 4 is transported to the auxiliary processing roller 24 of the preheating mechanism 21 by the air pump 26. The fire blanket is preheated by the auxiliary processing roller 24, which improves the hot pressing efficiency. After the hot pressing is completed, the fire blanket output from the heat collection box 18 is cooled by the auxiliary processing roller 24 of the cooling mechanism 22.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, material, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, material, or apparatus.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
