Description

Technical Field

[0001] This utility model relates to the technical field of anti-scalding protection mechanisms for hot-drilling machines, specifically an anti-scalding protection mechanism for hot-drilling machines. Background Technology

[0002] As a core hot-pressing equipment in the light industrial manufacturing sectors such as clothing, footwear, and bags, the core function of a hot-pressing machine is to melt the hot-melt adhesive layer of hot-pressing rhinestones (such as resin rhinestones, water rhinestones, and metal rhinestones) using heating components, allowing the rhinestones to firmly adhere to the substrate surface, thus enabling the mass production of decorative patterns. With the increasing demand for personalized product appearance in the consumer market, the application scenarios of hot-pressing machines have expanded from traditional garment processing to fields such as cultural and creative products and home decorations, significantly increasing the frequency of equipment use and operational intensity.

[0003] Currently, Chinese patent CN214782862U discloses a hot-pressing machine for strip drills. The key technical features include a frame, a hot-pressing component axially rotatably connected to the frame, a drive device for rotating the hot-pressing component, and a guide frame on the frame for guiding the strip drills and strip-shaped workpieces towards the hot-pressing component. The hot-pressing component has a cylindrical structure with a circular hot-pressing working surface on its outer contour. An electric heating element is provided on the hot-pressing component. The frame also includes a hot-pressing strip for pressing the strip drills and workpieces onto the hot-pressing working surface, and feed rollers and discharge rollers axially rotatably connected to the frame for winding the hot-pressing strip. Multiple guide rollers are provided, and each guide roller cooperates with the feed and discharge rollers to form a C-shaped annular structure around the hot-pressing strip. This improves the applicability and processing effect of the hot-pressing machine.

[0004] The aforementioned hot-drill strip machine still has some problems in actual use. Because its outlet directly receives the hot-pressed strip drills and strip-shaped materials to be processed, it is easy to form a local high-temperature area. When the operator picks up the materials, it is easy to directly touch the high-temperature finished product, resulting in skin burns. Utility Model Content

[0005] The purpose of this utility model is to provide a heat protection mechanism for a hot rhinestone machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A heat protection mechanism for a hot rhinestone machine includes L-shaped plates fixedly installed on both sides of the outlet of the hot rhinestone machine. The upper parts of the two sets of L-shaped plates are connected by a rotating connector to a protective cover for covering the outlet of the hot rhinestone machine. The lower parts of the two sets of L-shaped plates are connected by a detachable U-shaped groove. The bottom of the U-shaped groove has an outlet for the processed material to pass through. The outer inner wall of the U-shaped groove is provided with an air blowing component for blowing gas onto the surface of the processed material. The inner inner wall of the U-shaped groove is provided with an air extraction component for extracting heat from the processed material and discharging it to the outside.

[0007] As a preferred technical solution, the air blowing component includes a rectangular mounting tube fixedly inserted into the upper surface of the front side of the U-shaped groove. The outer opening of the rectangular mounting tube is connected to two sets of rectangular barrels, and the ends of the two sets of rectangular barrels are each inlaid with a second axial flow fan.

[0008] As a preferred technical solution, the air extraction component includes a square tube embedded in the upper inner wall of the U-shaped groove. The surface of the square tube in contact with the workpiece has several sets of air intake holes. The several sets of air intake holes are distributed in a rectangular array on the surface of the square tube. The two ends of the square tube are connected to rectangular tubes. The outer ends of the two sets of rectangular tubes are bent outward and abut against the corresponding side ends of the U-shaped groove. The outer ends of the two sets of rectangular tubes are each embedded with a first axial flow fan.

[0009] As a preferred technical solution, the rotating connector includes a transition rod fixedly installed between the upper ends of the two sets of L-shaped plates, and a fixing ring is rotatably connected to the surface of the transition rod, and the surfaces of the two sets of fixing rings are respectively fixedly connected to the surface of the protective cover.

[0010] As a preferred technical solution, the detachable component includes fixing plates that are fixedly connected to the bottom of the outer side of the L-shaped plate. Fixing bolts are provided on the surfaces of both sets of fixing plates. The fixing bolts pass through the corresponding side fixing plates and are threaded to the surface of the U-shaped groove.

[0011] As a preferred technical solution, the front surface of the protective cover is provided with an observation window, and the bottom of both sides of the protective cover is provided with abutment strips, the bottom of the two sets of abutment strips contacting the surface of the corresponding L-shaped plate.

[0012] As a preferred technical solution, the surface of the L-shaped plate is provided with several sets of mounting holes for connecting a hot-drilling machine.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a protective cover that, when closed, effectively prevents the heat inside the discharge port from spreading disorderly to the surrounding environment. This avoids direct high-temperature radiation to the operator's work area, reducing the risk of burns to operators who are near the discharge port and improving operational safety. At the same time, it reduces the impact of heat on the surrounding environment temperature, preventing a decrease in work comfort due to localized high temperatures.

[0014] This invention utilizes a combination of a blowing component and an extraction component. A second axial flow fan draws in external gas, which is then directionally blown onto the surface of the workpiece just exiting the drilling machine through a rectangular barrel and rectangular mounting pipe. This quickly removes a large amount of heat from the surface of the workpiece, preventing localized high-temperature accumulation due to direct exposure of the workpiece to the exit area. Subsequently, the rectangular pipe adheres to the surface of the workpiece, and the rectangular array of suction holes, under the negative pressure of the first axial flow fan, not only extracts residual heat from the deeper layers of the workpiece but also simultaneously removes the hot air carried by the blowing component during the blowing process. The hot air is then discharged to the outside, away from the material handling area, through the rectangular pipe. This combination forms a dual cooling mode that first lowers the surface temperature and then removes deep heat, significantly accelerating the cooling speed of the workpiece. This allows the workpiece to reach a safe touch temperature before the operator handles it, eliminating the risk of burns caused by the operator's hands touching the high-temperature finished product.

[0015] This invention utilizes an observation window and abutment strips. An observation window on the front surface of the protective cover allows operators to observe the material conveying process at the hot-drilling machine's outlet in real time without opening the cover. This enables timely detection of any abnormalities during material conveying, facilitating rapid response and preventing damage to the material or escalation of equipment malfunctions due to delayed observation. This enhances the convenience and timeliness of operational monitoring. Furthermore, abutment strips are located at the bottom of both sides of the protective cover. When the cover is closed to cover the outlet, the bottom of the abutment strips makes close contact with the corresponding L-shaped plate surface, filling the gap between the cover and the L-shaped plate. This improves the sealing of the cover, further reducing the possibility of external debris entering the outlet and internal heat dissipation, thus enhancing the protective effect of the cover.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This embodiment provides a scalding protection mechanism for a hot rhinestone machine, including L-shaped plates 100 fixedly installed on both sides of the outlet of the hot rhinestone machine. A protective cover 104 for covering the material outlet 109 of the hot rhinestone machine is connected between the upper parts of the two sets of L-shaped plates 100 via a rotating connector. A U-shaped groove 106 is detachably connected between the lower parts of the two sets of L-shaped plates 100 via a detachable connector. The bottom of the U-shaped groove 106 has an outlet 109 for the processed material to pass through. An air blowing mechanism for blowing gas onto the surface of the processed material is provided on the inner wall of the outer side of the U-shaped groove 106. The inner wall of the U-shaped groove 106 is equipped with an air extraction device for extracting heat from the processed material and discharging it to the outside. With the protective cover 104 installed, the protective cover 104 can effectively prevent the heat inside the discharge port 109 from spreading disorderly to the surrounding environment after it is closed, avoid the direct radiation of high temperature to the operator's work area, reduce the risk of the operator being burned by high temperature due to proximity to the discharge port 109, improve operational safety, and at the same time reduce the impact of heat on the surrounding temperature, avoiding a decrease in the comfort of the working environment due to local high temperature.

[0020] The air blowing component includes a rectangular mounting tube 301 fixedly inserted into the upper front surface of the U-shaped groove 106. The outer opening of the rectangular mounting tube 301 is connected to two sets of rectangular barrels 300, and the ends of the two sets of rectangular barrels 300 are each inlaid with a second axial flow fan 302. The extraction component includes a square tube 200 embedded in the upper inner wall of the U-shaped groove 106. Several sets of suction holes 203 are formed on the surface of the square tube 200 that contacts the workpiece. These suction holes 203 are arranged in a rectangular array on the surface of the square tube 200. Rectangular tubes 201 connect to both ends of the square tube 200. The outer ends of the two sets of rectangular tubes 201 are bent outwards and abut against the corresponding ends of the U-shaped groove 106. A first axial flow fan 202 is embedded in the outer ends of both sets of rectangular tubes 201. Through the cooperation of the blowing component and the extraction component, the second axial flow fan 302 draws in external gas, which is then directionally blown onto the surface of the workpiece just delivered from the outlet of the hot-drilling machine via the rectangular barrel 300 and the rectangular mounting pipe 301. This can quickly remove a large amount of heat from the surface of the processed material, preventing the processed material from being directly exposed to high temperatures in the outlet area and forming local high-temperature accumulation. Subsequently, the square tube 200 fits against the surface of the processed material, and the rectangular array of suction holes 203, under the negative pressure of the first axial flow fan 202, not only extracts the residual heat deep in the processed material, but also simultaneously sucks away the hot air carried by the blowing component during the blowing process. The hot air is then discharged to the outside away from the material picking area through the rectangular tube 201. The two work together to form a dual cooling mode of first reducing the surface temperature and then removing the deep heat, which greatly accelerates the cooling speed of the processed material, so that the processed material can be reduced to a safe touch temperature before the operator picks it up, eliminating the risk of burns caused by the operator's hands touching the high-temperature finished product.

[0021] Among them, the first axial fan 202 and the second axial fan 302 can be selected from one of the following: German Ziehl-Robbins FN050-4EK.4I.V7, Ningbo Langwei Electric LWAE series, and hicoolfans axial fan series.

[0022] The rotating connector includes a transition rod 101 fixedly installed between the upper ends of the two sets of L-shaped plates 100. A fixing ring 102 is rotatably connected to the surface of the transition rod 101. The surfaces of the two sets of fixing rings 102 are fixedly connected to the surface of the protective cover 104. Through the rotating connector, the two sets of fixing rings 102 are rotatably connected to the surface of the transition rod 101 and fixedly connected to the protective cover 104, allowing the protective cover 104 to rotate flexibly around the transition rod 101. This ensures smooth rotation of the protective cover 104, preventing damage or operational inconvenience due to poor rotation. Simultaneously, operators can easily rotate the protective cover 104 to open and close it according to actual needs. When open, it facilitates inspection, maintenance, or handling of abnormal material conveying inside the hot-drilling machine's outlet 109. When closed, it reliably covers the outlet 109 to provide protection, enhancing the flexibility and reliability of the protective cover 104.

[0023] The detachable components include fixing plates 108 that are fixedly connected to the bottom outer side of the L-shaped plate 100. Fixing bolts 107 are threaded through the surfaces of both fixing plates 108. The fixing bolts 107 penetrate the corresponding fixing plates 108 and are threaded onto the surface of the U-shaped groove 106. Through the detachable components, the two fixing plates 108 are fixed to the bottom outer side of the L-shaped plate 100, providing a stable mounting carrier for the fixing bolts 107. The fixing bolts 107 penetrate the fixing plates 108 and are threaded onto the surface of the U-shaped groove 106. The tightness of the threaded connection ensures a secure connection between the U-shaped groove 106 and the L-shaped plate 100, preventing loosening or displacement of the U-shaped groove 106 during material handling and component operation. Simultaneously, the detachable nature of the threaded connection makes disassembly of the U-shaped groove 106 convenient. When internal components of the U-shaped groove 106 need maintenance or replacement, or when the U-shaped groove 106 itself needs cleaning, simply removing the fixing bolts 107 allows the U-shaped groove 106 to be removed, simplifying the maintenance process.

[0024] The protective cover 104 has an observation window 103 on its front surface and abutment strips 105 on both sides of its bottom. The bottoms of the two sets of abutment strips 105 contact the surfaces of the corresponding L-shaped plates 100. Through the observation window 103 and the abutment strips 105, the operator can observe the material conveying process inside the hot-drilling machine's outlet 109 in real time without opening the protective cover 104. This allows for timely detection of any abnormalities in the material conveying process, facilitating rapid response and preventing delays caused by insufficient response time. This allows for timely observation of potential damage to processed materials or escalation of equipment malfunctions, enhancing the convenience and timeliness of operation monitoring. Furthermore, the bottom of both sides of the protective cover 104 is equipped with abutment strips 105. When the protective cover 104 is closed to cover the discharge port 109, the bottom of the abutment strips 105 can make close contact with the surface of the corresponding L-shaped plate 100, filling the gap between the protective cover 104 and the L-shaped plate 100, improving the sealing performance of the protective cover 104, further reducing the possibility of external debris entering the discharge port 109 and internal heat dissipation, and enhancing the protective effect of the protective cover 104.

[0025] The protective cover 104 can be made of stainless steel or aluminum alloy, and has an internal cavity filled with one of glass fiber cotton or aerogel felt, while the outer surface is coated with one of ceramic heat insulation coating or silicone high temperature heat insulation coating.

[0026] The L-shaped plate 100 has several sets of mounting holes 110 for connecting to the hot-drilling machine. By setting the mounting holes 110, the L-shaped plate 100 has several sets of mounting holes 110, providing multiple mounting points for the fixed connection between the L-shaped plate 100 and the hot-drilling machine. The operator can select the appropriate mounting holes 110 for fixing according to the actual installation conditions on both sides of the hot-drilling machine's outlet 109, ensuring that the L-shaped plate 100 can be stably and firmly installed on the hot-drilling machine, adapting to different installation scenario requirements.

[0027] Working principle; Two sets of L-shaped plates 100 are fixedly installed on both sides of the outlet of the hot-drilling machine through the mounting holes 110 on the surface of the L-shaped plate 100, providing a stable installation base for the entire device. The adapter rod 101 in the rotating connector is fixed at the upper end of the two sets of L-shaped plates 100. The protective cover 104 is rotatably connected to the adapter rod 101 through the fixing ring 102 on the surface. The operator can rotate the protective cover 104 to cover the outlet 109 of the hot-drilling machine, thereby protecting the outlet 109 and preventing external debris from entering or internal heat from spreading disorderly. Meanwhile, the observation window 103 on the front of the protective cover 104 allows operators to observe the conveying of the processed material in the discharge port 109 in real time, while the abutment strips 105 on the bottom of both sides of the protective cover 104 can abut against the surface of the L-shaped plate 100 when the protective cover 104 is closed, thereby improving the sealing performance of the protection. Meanwhile, the U-shaped groove 106 is fixed to the bottom outer side of the L-shaped plate 100 by the fixing plate 108, and the fixing bolt 107 passes through the fixing plate 108 and is threaded to the U-shaped groove 106, so as to achieve the stable installation of the U-shaped groove 106 and subsequent disassembly and maintenance. When the processed material after hot rhinestone processing is sent out from the discharge port 109 and enters the U-shaped groove 106 area, and passes out from the discharge port 109, the air blowing component and the air extraction component on the U-shaped groove 106 are activated in coordination to process the processed material. Regarding the air blowing component, the rectangular mounting tube 301, which is fixedly inserted into the upper front surface of the U-shaped groove 106, serves as a gas delivery channel. After the second axial flow fan 302, which is embedded at the ends of the two sets of rectangular barrels 300 connected to its outer opening, is started, it draws in external gas and delivers it through the rectangular barrels 300 to the rectangular mounting tube 301. Finally, the rectangular mounting tube 301 blows gas onto the surface of the processed material, which can initially cool the surface of the processed material. The air extraction components work synchronously. The square tube 200, which is embedded in the upper inner wall of the U-shaped groove 106, fits against the surface of the workpiece. Several sets of air extraction holes 203 are opened on the surface of the square tube 200 and are distributed in a rectangular array to ensure that the air extraction range evenly covers the surface of the workpiece. Under the negative pressure of the first axial flow fan 202 at the end of the rectangular tube 201, the residual heat on the surface of the workpiece and the hot air carried by the air blowing component are drawn into the square tube 200. Then, the hot air is drawn in through the rectangular tube 201 connected at both ends of the square tube 200, and finally the hot air is discharged to the outside by the first axial flow fan 202, so as to achieve deep cooling of the workpiece and rapid heat discharge.

[0028] 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.
