[0002] Firefighting gloves are a kind of labor protection products, which are often used in the field of firefighting. Such gloves need to achieve special fire resistance and burning resistance. In addition, according to different use occasions, the required performances are also different, such as corrosion resistance, impact resistance, pressure resistance, etc. Therefore, most of the current firefighting gloves are made by extruding and compounding multiple materials at the same time. For the preparation of such composite materials, surface heat treatment process needs to be applied, and surface heat treatment can effectively improve the material performance and enhance the strength of the material.

[0003] Among the current firefighting gloves, there is an impact-resistant fabric similar to Kevlar. This type of fabric needs to be surface hardened to make its surface alloyed, making it more suitable for the composite preparation of firefighting gloves. However, during the surface heating process of such substrates, it is difficult to quickly control the temperature, and the substrate is prone to overheating, resulting in excessive heating of the substrate surface, which not only affects the subsequent use of the material, but also during the continuous heating process, the surface of the hot roller will be contaminated with more thermal residues, affecting the subsequent continuous heating operation.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a driving roller driven by a thermal control mechanism to swing on one side of the hot melt roller. When it is detected that the heating temperature of the substrate is too high, the threaded rod can directly drive the pushing groove plate to move to one side through the threaded tube, and a pushing pin slides inside the pushing groove plate. The pushing pin is forced to swing with the axis rod as the center of the circle. The swing rod and the driving roller also swing synchronously. During the swinging process of the driving roller, the top of the substrate is squeezed to move downward, thereby reducing the contact area between the substrate and the hot melt roller. In this way, under the condition of a constant rotation speed, the contact time between the substrate and the hot melt roller is shorter, thereby achieving the effect of controlling the degree of heating. Compared with the temperature control in the prior art, the effect is faster.

[0021] The present invention arranges a scraper plate above one side of the hot melt roller, and the scraper plate directly engages with the meshing groove on the outer surface of the threaded barrel through meshing teeth. When the threaded barrel is forced to move and drive the roller to swing, the meshing teeth are forced to rotate and drive the scraper plate to rotate a certain angle, so that the edge position of the scraper plate fits with the surface of the hot melt roller, thereby scraping off the slag on the surface of the hot melt roller, preventing the accumulation of slag on the surface of the hot melt roller from affecting the subsequent chemical heat treatment of the substrate;

[0022] The present invention provides a clutch mechanism, whereby the active motor can directly drive the cleaning brush to rotate on the top of the support platform under normal circumstances to clean the surface of the scraper plate, and the cleaned slag will fall into the collecting bin for collection, while the electric rod will drive the pressure wheel to rise a certain distance, so that the blocking belt and the pulley on the output shaft of the active motor are loosened to cause slippage, so that the driving effect of the active motor will only drive the cleaning brush to rotate to clean the scraper plate, while the blocking belt does not move, so that the blocking wheel will not drive the threaded rod to rotate, thereby fixing the position of the driving roller.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] refer to Figure 1 , comprising a heat treatment cabinet 1, wherein a hot melt roller 2 and a pressure roller 3 are rotatably arranged inside the heat treatment cabinet 1, a substrate 4 is wound between the hot melt roller 2 and the pressure roller 3, one end of the hot melt roller 2 is directly driven by a motor to rotate in the heat treatment cabinet 1, and the hot melt roller 2 heats the substrate 4 on its surface through an electric heating component at the other end;

[0037] A scraping mechanism 5 is arranged above one side of the hot melt roller 2, and the scraping mechanism 5 includes a scraping plate 51 and a support 52. The support 52 fixed inside the heat treatment cabinet 1 is provided with a plurality of cleaning brushes 53 on its top surface, and the cleaning brushes 53 clean the surface of the scraping plate 51. A collecting drawer 10 is arranged below the cleaning brushes 53 inside the heat treatment cabinet 1, and the plurality of cleaning brushes 53 are drivingly connected to an active motor 6 fixed on one side of the heat treatment cabinet 1.

[0038] The output shaft of the active motor 6 is also connected to a clutch mechanism 7. The active motor 6 directly drives the two sets of thermal control mechanisms 8 to move laterally on both sides of the heat treatment cabinet 1 through the clutch mechanism 7. The clutch mechanism 7 can realize the transmission separation between the active motor 6 and the thermal control mechanism 8.

[0039] A driving roller 9 is also provided at one side of the hot melt roller 2, and the driving roller 9 is located at the top of the substrate 4. The thermal control mechanism 8 includes a pushing groove plate 81, a rocker assembly 82, a threaded cylinder 83 and a threaded rod 84. The threaded rod 84 is transmission-connected to the clutch mechanism 7, and the threaded cylinder 83 is fixed on one side of the pushing groove plate 81. The pushing groove plate 81 drives the driving roller 9 to swing in an arc inside the heat treatment cabinet 1 through the rocker assembly 82.

[0040] In this embodiment, the hot melt roller 2 and the pressure roller 3 are located inside the heat treatment cabinet 1 and are movably supported by a support frame. The pressure roller 3 can ensure that a high pressure is generated between the hot melt roller 2 through a pressing component, thereby squeezing the substrate 4 and achieving the effect of high-pressure heat treatment. In this way, when the hot melt roller 2 is driven to rotate by the motor component, the substrate 4 subjected to the force will be driven to move forward, thereby achieving the effect of continuous heat treatment;

[0041] The scraper plate 51 on one side of the hot melt roller 2 is not in contact with the surface of the hot melt roller 2 under normal circumstances. When the hot melt roller 2 overheats the substrate 4 during the heat treatment, a part of the molten slag particles of the substrate 4 will adhere to the hot melt roller 2. At this time, the scraper plate 51 will be rotated by force to fit the surface of the hot melt roller 2, so that the scraper plate 51 can achieve a cleaning effect under the rotation operation of the hot melt roller 2. The cleaned slag particles are driven to rotate to fit the cleaning brush 53, so that they fall under the rotation cleaning of the cleaning brush 53 and finally fall into the collecting bin 10 for collection.

[0042] The rotation of several groups of cleaning brushes 53 is directly driven by the active motor 6, and the active motor 6 can simultaneously drive the thermal control mechanism 8 to move laterally inside the heat treatment cabinet 1 through the clutch mechanism 7. Specifically, when the threaded rod 84 is driven to rotate by the clutch mechanism 7, the threaded cylinder 83 is forced to move to one side, and at this time, the pushing groove plate 81 synchronously moves the pushing swing arm assembly 82, and the swing arm assembly 82 is forced to drive the driving roller 9 to rotate inside the heat treatment cabinet 1, and the driving roller 9 is located above the substrate 4, so that the driving roller 9 can drive the substrate 4 to separate from the hot melt roller 2, so that the actual contact area between the substrate 4 and the hot melt roller 2 is reduced. In this way, when there is no contact and the hot melt roller 2 rotates constantly, the actual heat treatment time of the substrate 4 is greatly reduced, thereby effectively controlling the temperature of the surface of the substrate 4 to prevent excessive heat treatment from causing damage to the material structure of the substrate 4.

[0043] refer to Figure 1 The threaded rod 84 is threadedly connected with the threaded barrel 83. The threaded barrel 83 slides horizontally on the inner wall of the heat treatment cabinet 1 through the slider, and the extension rod 85 is fixed on the side of the pushing slot plate 81 away from the threaded barrel 83. The surface of the extension rod 85 is slidably connected to the sliding seat 87. The side of the surface of the extension rod 85 close to the sliding seat 87 is sleeved with a return spring 86. The bottom of the sliding seat 87 is rotatably connected to the resistance roller 88. The rotation of the threaded rod 84 drives the threaded barrel 83 to slide to one side, and at the same time drives the resistance roller 88 to fit the substrate 4 on one side of the hot melt roller 2. The surface of the extension rod 85 is provided with a convex ring for limiting the specific position of the sliding seat 87.

[0044] In this embodiment, during the rotation of the threaded rod 84, the threaded barrel 83 is limited by sliding with the heat treatment cabinet 1, and the threaded barrel 83 and the threaded rod 84 are threadedly connected, so that the threaded barrel 83 is forced to move to one side, and one side of the threaded barrel 83 is fixed to the pushing groove plate 81, and the pushing groove plate 81 moves to one side synchronously;

[0045] At the same time, an extension rod 85 is fixed to the other side of the pushing groove plate 81, and the surface of the extension rod 85 is slidably sleeved on the sliding seat 87. At the same time, the extension rod 85 is elastically connected to the sliding seat 87 through the return spring 86. When the extension rod 85 drives the resistance roller 88 under the sliding seat 87 to move to contact with the hot melt roller 2, at this time, under the resistance of the resistance roller 88, the substrate 4 can maintain good contact with the hot melt roller 2, thereby preventing excessive separation of the substrate 4 and the hot melt roller 2, which will lead to insufficient contact area between the actual substrate 4 and the hot melt roller 2. The continuous movement of the extension rod 85 allows the sliding seat 87 to squeeze the return spring 86 on the surface of the extension rod 85, so that the resistance roller 88 can better resist the surface of the hot melt roller 2 under the elastic resistance force of the return spring 86, thereby limiting the minimum contact position of the substrate 4.

[0046] refer to Figure 1 The swing rod assembly 82 includes a swing rod 821, an axis rod 822 and a push pin 823. The axis rod 822 is fixed at a position near one end of the swing rod 821. The swing rod 821 rotates inside the heat treatment cabinet 1 through the axis rod 822. The push pin 823 is fixed at one end of the swing rod 821 away from the axis rod 822. The push pin 823 is slidably connected to the inner wall of the push slot plate 81. The slot surface of the push slot plate 81 is inclined. The driving roller 9 is movably arranged at one end of the swing rod 821 away from the push pin 823 through a shaft sleeve. The axis position of the axis rod 822 is located in the first quadrant of the end surface of the hot melt roller 2.

[0047] In the present embodiment, when the pushing groove plate 81 moves to one side, the pushing pin 823 slides inside it, and the pushing pin 823 is fixed to the swing rod 821. In this way, after the pushing pin 823 is subjected to force, the swing rod 821 as a whole will swing with the axis rod 822 as the center. The axis position is located in the first quadrant of the end face of the hot melt roller 2, so that when the swing rod 821 rotates to be perpendicular to the ground, the substrate 4 can be driven by the roller 9 to expand to the maximum angle, thereby achieving a better separation effect and preventing the hot melt roller 2 from excessively heat treating the substrate 4.

[0048] refer to Figure 1 The clutch mechanism 7 includes a blocking belt 72 and two groups of blocking wheels 71. The blocking belt 72 is sleeved on the surfaces of the two groups of blocking wheels 71. A threaded rod 84 is directly fixed on one side of the blocking wheel 71. The output shaft of the active motor 6 is sleeved with the upper position of the blocking belt 72 through a pulley. A pressure wheel 73 is pressed on the lower side of the outer side of the blocking belt 72 near the left and right sides of the active motor 6. The pressure wheel 73 is movably connected to the output rod of the electric rod 74 through a connecting seat. The electric rod 74 is fixed on the surface of the heat treatment cabinet 1. The electric rod 74 drives the pressure wheel 73 to tension the blocking belt 72. A tensioning wheel 75 is sleeved at the lower position of the blocking belt 72. One side of the tensioning wheel 75 is movably connected to the movable seat 76 through a shaft rod. An L-shaped frame 77 is fixed at a position of the heat treatment cabinet 1 near the movable seat 76. The movable seat 76 slides in the L-shaped frame 77 through a spring elasticity.

[0049] In this embodiment, the threaded rod 84 is fixed to the blocking wheel 71, the surface of the blocking wheel 71 is sleeved with the blocking belt 72, and the blocking belt 72 is sleeved with the output shaft of the active motor 6 through the pulley, so that when the active motor 6 rotates, the blocking wheel 71 can be driven to rotate, thereby achieving the basic transmission purpose;

[0050] At the same time, the outer position of the blocking belt 72 close to the left and right sides of the active motor 6 is pressurized by two sets of pressure wheels 73. At this time, the blocking belt 72 is tightened to drive the blocking wheel 71 to rotate, and the pressure wheel 73 is controlled by the electric rod 74 to move up and down on one side of the heat treatment cabinet 1. When the electric rod 74 drives the pressure wheel 73 to rise, the blocking belt 72 loses its grip on the active motor 6, causing slippage between the pulley of the active motor 6 and the blocking belt 72. In this way, the active motor 6 only needs to drive the cleaning brush 53 to rotate to achieve cleaning, and the threaded rod 84 will not be driven, thereby stabilizing the position of the driving roller 9.

[0051] refer to Figure 1 The end position of one side of the scraper plate 51 is set in the heat treatment cabinet 1 through a shaft connection, and the surface of the shaft connection is fixedly connected to the meshing teeth 57. The meshing teeth 57 are meshed with the bite grooves on the surface of the threaded tube 83. The threaded tube 83 moves laterally and drives the scraper plate 51 to flip inside through the meshing teeth 57.

[0052] In this embodiment, the meshing teeth 57 mesh with the bite grooves on the surface of the threaded tube 83. When the threaded rod 84 rotates to drive the threaded tube 83 to move horizontally, the meshing teeth 57 rotate to synchronously drive the scraper plate 51 to flip over inside the heat treatment cabinet 1, so that the scraper plate 51 docks with the surface of the hot melt roller 2. At this time, the scraper plate 51 can scrape and clean the slag generated by excessive hot melting on the surface of the hot melt roller 2, and the cleaned slag accumulates on the surface of the scraper plate 51. After the scraper plate 51 is flipped again, the scraper plate 51 can dock with the cleaning brush 53 in the rotating state. At this time, the rotating cleaning brush 53 can clean up the slag and collect it in the collection bin 10.

[0053] refer to Figure 1 A plurality of groups of transmission teeth 54 are also provided between the cleaning brush 53 and the support platform 52. The plurality of groups of transmission teeth 54 mesh with each other. A single group of cleaning brushes 53 is fixed to a single group of transmission teeth 54. The bottom of the single group of transmission teeth 54 is fixed to a reversing tooth 55 through a connecting shaft. The transmission teeth 54 are connected to a transmission belt assembly 56 through the reversing tooth 55. The top of the transmission belt assembly 56 is connected to an output shaft of an active motor 6 through a pulley. The active motor 6 directly drives the plurality of groups of cleaning brushes 53 to rotate on the top of the support platform 52.

[0054] In this embodiment, a plurality of groups of cleaning brushes 53 correspond to a plurality of groups of transmission teeth 54, and the transmission teeth 54 are meshed and connected with each other. A single group of transmission teeth 54 and cleaning brushes 53 are connected to the reversing teeth 55 through a connecting shaft, so that when a single group of reversing teeth 55 rotates, a plurality of groups of cleaning brushes 53 will rotate synchronously, thereby cleaning the slag on the surface of the scraper plate 51.

[0055] The specific structure of the reversing tooth 55 can be composed of two sets of mutually meshing bevel gears, which only provide a transmission purpose. At the same time, the other side of the reversing tooth 55 is connected to the bottom pulley of the transmission belt assembly 56, and the top pulley of the transmission belt assembly 56 is connected to the output shaft of the active motor 6. In this way, the drive of the active motor 6 can directly drive the transmission tooth 54 to rotate through the reversing tooth 55 and the transmission belt assembly 56, and then drive the cleaning brush 53 to rotate on the support platform 52 to achieve the cleaning of the slag on the surface of the scraper plate 51.

[0056] Working principle: when excessive hot melting is detected on the surface of the substrate 4, the active motor 6 is first started, and the output shaft of the active motor 6 drives the blocking belt 72 to move through the driving wheel. The two sets of blocking wheels 71 respectively drive the threaded rods 84 in the two sets of thermal control mechanisms 8 to rotate, and the threaded rods 84 are threadedly connected with the threaded cylinder 83. At the same time, the threaded cylinder 83 is slidably limited by the heat treatment cabinet 1, so that the threaded cylinder 83 pulls the pushing slot plate 81 and the extension rod 85 to move to one side. During the movement of the pushing slot plate 81, the pushing pin 823 inside it is forced to drive the swing rod 821 to swing with the shaft rod 822 as the center, and the driving roller 9 at one end of the swing rod 821 is driven to swing, driving the substrate 4 to move downward, so that it is partially separated from the hot melt roller 2, reducing the contact area. At the same time, the extension rod 85 drives the contact roller 88 at the bottom of the sliding seat 87 to contact the other side of the hot melt roller 2, ensuring the contact effect of the contact roller 88 and the substrate 4, thereby ensuring the minimum contact area size;

[0057] When the threaded barrel 83 moves laterally, the meshing teeth 57 in the scraping mechanism 5 mesh with the biting grooves on the surface of the threaded barrel 83, so that the meshing teeth 57 rotate synchronously, thereby driving the scraping plate 51 to rotate until it fits with the surface of the hot melt roller 2. At this time, the hot melt roller 2 in the rotating state can cooperate with the scraping plate 51 to scrape off the slag on the surface of the hot melt roller 2, and the scraped slag docks on the surface of the scraping plate 51.

[0058] After the temperature adjustment of the hot melt roller 2 is completed, the active motor 6 is reversed to reset all components. At this time, the scraper plate 51 is driven by the reverse movement of the threaded cylinder 83 so that it contacts the cleaning brush 53 on the top of the support platform 52. Then, the electric rod 74 in the clutch mechanism 7 is started to drive the pressure wheel 73 to move upward for a distance. After the blocking belt 72 loses the resistance force of the pressure wheel 73, the gripping force between it and the pulley of the active motor 6 disappears, thereby slipping. At this time, the drive of the active motor 6 will drive the reversing gear 55 to rotate through the transmission belt assembly 56, and the reversing gear 55 directly drives several groups of cleaning brushes 53 to rotate on the top of the support platform 52 through the transmission gear 54, thereby cleaning the scraper plate 51, and the cleaned slag falls into the collecting bin 10 for collection.
