[0003] The filter screen in the existing baking machine is located in the interior of the baking machine, and the filter screen is mainly used to filter dust and other impurities in the air to prevent the fabric from being contaminated. During the maintenance process, the maintenance door needs to be opened to enter the interior of the baking machine to disassemble and replace the filter screen. Since the interior of the baking machine has an environment temperature of 200 degrees, scalding is likely to occur during the maintenance process. Therefore, the baking machine usually needs to be cooled to an appropriate temperature during maintenance, which will prolong the maintenance time, and it will also take more time to start the baking machine again, which is not conducive to production. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the present application clearer, further detailed description of the present application is made below in combination with embodiments and drawings, the illustrative embodiments and their descriptions of the present application are only used to explain the present application, and do not limit the present application.

[0051] As shown in Figures 1-2 The present application provides a roaster convenient to maintain, which comprises a shell 1, a slide 2, a mounting frame 4, a sealing frame 6 and a driving member 9; the shell 1 is provided with an access hole 3, and a maintenance door is arranged in the access hole 3 to communicate / insulate the inside and outside of the shell 1; the slide 2 is located in the shell 1, wherein one end of the slide 2 corresponds to the position of an air inlet port 8 of an air duct 7, and the other end corresponds to the position of the access hole 3; the mounting frame 4 is in sliding cooperation with the slide 2, and the mounting frame 4 is used for detachably connecting a filter screen 5; the sealing frame 6 is connected to the edge of the air inlet port 8 of the air duct 7; the driving member 9 is connected with the shell 1 and in transmission connection with the mounting frame 4; in a working state, the mounting frame 4 can slide back and forth on the slide 2 under the driving of the driving member 9 and can form a sliding sealing cooperation with the sealing frame 6.

[0052] The roaster convenient to maintain provided by the present application can make the filter screen 5 reach the corresponding position of the air inlet port 8 of the air duct 7 after the filter screen 5 is installed on the mounting frame 4 through the cooperation of the slide 2 and the mounting frame 4, so as to filter the dust in the air, and when it is necessary to dismount and replace, the filter screen 5 can reach the access hole 3 from the corresponding position of the air inlet port 8 of the air duct 7, so that the maintenance personnel can conveniently dismount the filter screen 5 outside the roaster, and the probability of safety accidents is greatly reduced; since the maintenance personnel no longer need to enter the inside of the roaster, it is no longer necessary to wait for a long time for the roaster to cool down; at the same time, through the setting of the sealing frame 6, the sealing property between the mounting frame 4 and the air duct 7 when the mounting frame 4 reaches the corresponding position of the air inlet port 8 can be ensured, so as to prevent the dust from leaking into the roaster, and the finished product quality of the fabric can be ensured.

[0053] In the present application, the extension direction of the access hole 3 opened on the shell 1 is perpendicular to the extension direction of the air inlet port 8 of the air duct 7, that is, after the slide 2 is connected perpendicularly to the inner wall of the shell 1, the mounting frame 4 can move on the slide 2 along a direction perpendicular to the extension direction of the air inlet port 8 of the air duct 7, and at the same time, the filter screen 5 installed in the mounting frame 4 moves in a sliding process, and the filter screen 5 and the surface where the air inlet port 8 of the air duct 7 is located are parallel to each other.

[0054] In the embodiment of the present application, the slide 2 can adopt a channel steel and be fixedly connected with the inner wall of the shell 1, and the outer side of the mounting frame 4 is provided with a protrusion 41 adapted to the channel structure of the channel steel. The number of the slide 2 is two, which respectively form a sliding fit with the two sides of the mounting frame 4, one end of the two slides 2 is respectively located on the two sides of the access hole 3, and the other end is respectively located on the two sides of the air inlet port 8 of the air duct 7. The end of the slide 2 close to the access hole 3 can not be provided with a limiting piece, that is, the mounting frame 4 can slide out of the shell 1 from the slide 2, thereby facilitating the operation, and the end of the slide 2 close to the air inlet port 8 of the air duct 7 is provided with a limiting structure, which can be achieved by providing a limiting block in the groove structure, thereby enabling the filter screen 5 in the mounting frame 4 to correspond to the position of the air inlet port 8 of the air duct 7.

[0055] In some optional embodiments, the overall shape of the mounting frame 4 can be a rectangular frame, and the mounting frame 4 can specifically include a first retaining rod, a second retaining rod and a third retaining rod. One end of each of the two second retaining rods is perpendicularly connected with two ends of the first retaining rod, and each of the two second retaining rods is provided with a protrusion 41 to form a sliding fit with the groove structure in the slide 2. Two protrusions 41 can be provided on each second retaining rod. One end of the third retaining rod is rotationally connected with the other end of one of the second retaining rods, and the other end of the third retaining rod is detachably connected with the other end of the other second retaining rod. In actual implementation, a commonly used lock catch structure on a window can be used to achieve the detachable connection between the third retaining rod and the second retaining rod for easy operation, and the rotational connection between the third retaining rod and the other second retaining rod can be achieved by a hinge connection. The inner sides of the first retaining rod, the second retaining rod and the third retaining rod are provided with sealing grooves adapted to the retaining frame of the filter screen 5.

[0056] In the embodiment of the present application, the mounting frame 4 can be opened by releasing the connection between the third retaining rod and the second retaining rod, thereby facilitating the disassembly and assembly of the filter screen 5 and improving the operation convenience. Meanwhile, the sealing grooves can ensure the assembly sealing between the filter screen 5 and the mounting frame 4, and avoid the leakage of dust due to the large gap between the filter screen 5 and the mounting frame 4.

[0057] In some optional embodiments, steel balls 42 are provided on the second retaining rod or the slide 2 by a groove ball process.

[0058] In the embodiment of the present application, the provision of the steel balls 42 can improve the smoothness of the sliding between the mounting frame 4 and the slide 2. Preferably, the steel balls 42 are provided on the second retaining rod, which is more convenient to implement, requires less amount of steel balls 42 and has relatively low implementation cost compared to providing the steel balls 42 on the slide 2.

[0059] In some optional embodiments, reference can be made to Figure 4The driving member 9 can specifically include a rotating handle 91, a gear set, a ball screw 92, and a ball nut 93. The rotating handle 91 is rotationally connected with the shell 1. Specifically, the rotating handle 91 has a rotating shaft, one end of the rotating shaft is movably arranged through the shell 1 and located inside the shell 1, and the other end is located outside the shell 1 as an operating end of the maintenance personnel. The rotating handle 91 and the shell 1 are respectively provided with a latch hole, so that the relative positioning of the rotating handle 91 and the shell 1 can be realized by using a latch to cooperate with the two latch holes. The gear set is located inside the shell 1 and is in transmission connection with the rotating handle 91, that is, the gear set is in transmission connection with one end of the rotating shaft located inside the shell 1. By rotating the rotating handle 91, driving force can be transmitted to the gear set. The ball screw 92 is arranged in parallel with the slide 2 inside the shell 1. In actual implementation, one end of the ball screw 92 can be rotationally connected with the slide 2, and the other end can be rotationally connected with the inner wall of the shell 1. The ball screw 92 is in transmission connection with the gear set, so that when the rotating handle 91 is rotated, the transmission of driving force is realized through the gear set, and finally the ball screw 92 can be driven to rotate. The ball nut 93 is connected with the mounting frame 4. The ball nut 93 is in transmission cooperation with the ball screw 92. When the ball screw 92 is driven to rotate, the ball nut 93 can drive the mounting frame 4 to slide back and forth on the slide 2.

[0060] In some optional embodiments, the gear set can specifically include an intermediate transmission rod 94, a first bevel gear pair 95, and a second bevel gear pair 96. The intermediate transmission rod 94 can be rotationally connected with the inner wall of the shell 1. One end of the intermediate transmission rod 94 is in transmission connection with the ball screw 92 through the first bevel gear pair 95. The other end of the intermediate transmission rod 94 is in transmission connection with the rotating handle 91 through the second bevel gear pair 96.

[0061] In the embodiments of the present application, by arranging the intermediate transmission rod 94, the first bevel gear pair 95, and the second bevel gear pair 96, the rotating handle 91 and the slide 2 can have a larger spacing in the length direction of the slide 2. Meanwhile, the spacing can be flexibly adjusted by replacing the intermediate transmission rod 94 with different lengths. In this way, the rotating handle 91 can be arranged at a position above the shell 1 which is convenient for operation, such as a position away from the maintenance opening 3, to avoid interference with the rotating handle 91 when the maintenance door is opened.

[0062] In some alternative embodiments, the sealing frame 6 is slidingly connected with the housing 1 to enable the sealing frame 6 to approach or move away from the air inlet port 8 of the air duct 7, the inner side edge of the sealing frame 6 is connected with the edge of the air inlet port 8 through the elastic corrugated plate 10 to enable the sealing frame 6 to have a tendency to approach the air inlet port 8, so that the sealing frame 6 and the air inlet port 8 can be kept in a sealed state through the elastic expansion of the elastic corrugated plate 10 during the sliding of the sealing frame 6 relative to the housing 1, and the sealing frame 6 is further provided with a sealing action member 11, the sealing action member 11 has a controlled end; in the working state, the mounting frame 4 can apply force to the controlled end to drive the sealing frame 6 to approach the mounting frame 4 when the mounting frame 4 slides to the position corresponding to the air inlet port 8.

[0063] In the embodiments of the present application, the sealing frame 6 can be elastically and sealingly slid relative to the housing 1 under the action of the elastic corrugated plate 10, and in the initial stage, the sealing frame 6 has a small spacing with the air inlet port 8, that is, when the mounting frame 4 slides to the position, the mounting frame 4 has a large spacing with the sealing frame 6, and this large spacing can allow the sealing frame 6 to expand to a certain extent in a high-temperature environment, thereby avoiding interference between the mounting frame 4 and the sealing frame 6 during sliding of the mounting frame 4, and during the sliding of the mounting frame 4, force can be applied to the controlled end to enable the sealing frame 6 to approach the mounting frame 4, and after the mounting frame 4 is in place, the sealing frame 6 can be in close contact with the mounting frame 4 and has a certain contact pressure to realize the sealing of the two.

[0064] In some alternative embodiments, reference can be made to Figure 3The sealing moving part 11 can specifically include a first fixed pulley 111, a second fixed pulley 112, a pulley seat 113, a driving rope 114, and a striker 115. The second fixed pulley 112 is fixed relative to the first fixed pulley 111. In actual implementation, the first fixed pulley 111 can be connected to the shell 1 through a connecting seat, and the first fixed pulley 111 can rotate freely on the connecting seat. The connecting seat is located on one side of the sealing frame 6, and the height of the first fixed pulley 111 relative to the shell 1 is higher than that of the sealing frame 6. The pulley seat 113 is connected to the shell 1, and the second fixed pulley 112 is connected to the pulley seat 113. The height of the second fixed pulley 112 relative to the shell 1 is equal to that of the first fixed pulley 111. One end of the driving rope 114 is sequentially wound around the first fixed pulley 111, the second fixed pulley 112, and the pulley seat 113, and the other end is connected to the sealing frame 6. The striker 115 is in sliding fit with the driving rope 114 between the pulley seat 113 and the second fixed pulley 112. The striker 115 can be in sliding fit with the pulley seat 113, and the length direction of the striker 115 is perpendicular to the segment between the one end of the driving rope 114 and the second fixed pulley 112. The other end of the striker 115 is used to contact the mounting frame 4. The sealing frame 6 is movably inserted into the shell 1 through the guide rod 12. When the striker 115 contacts the mounting frame 4, the striker 115 can continuously push the driving rope 114 to make the segment between the one end of the driving rope 114 and the second fixed pulley 112 bend during the continuous sliding of the mounting frame 4, so that the other end of the driving rope 114 can drive the sealing frame 6 to move. The sealing frame 6 slides to approach the mounting frame 4 under the guidance of the guide rod 12, and finally the sealing frame 6 and the mounting frame 4 are attached to realize sealing. It should be noted that the deformation amount of the sealing frame 6 caused by temperature change can be different, so the sliding distance required by the sealing frame 6 is also different. This means that the mounting frame 4 does not necessarily slide to a fixed position, as long as the sealing frame 6 and the mounting frame 4 can be attached to realize sealing. When the sealing frame 6 and the mounting frame 4 are attached, they only need to be in communication, and the specific attachment position of the sealing frame 6 and the mounting frame 4 is not limited.

[0065] In some optional embodiments, the surface of the access door corresponding to the access opening 3 is configured as an arc surface.

[0066] In the embodiments of the present application, the lower end of the access door is rotationally connected to the access opening 3. In this way, when the access door is opened, the high-temperature air in the baking machine can be discharged from above the access opening 3, avoiding the risk of scalding for the maintenance personnel. In the closed state of the access door, the axis corresponding to the arc surface is vertical, so that when the access door is opened, the high-temperature air in the baking machine rapidly spreads to the left and right under the guidance of the arc surface, avoiding the high-temperature air directly out of the baking machine to cause scalding to the maintenance personnel.

[0067] In some optional embodiments, an observation window is arranged on the access door.

[0068] In the embodiment of the present application, the observation window can facilitate the maintenance personnel to observe the inside of the roasting machine, so as to roughly judge the working state of the filter screen 5. Correspondingly, after the observation window is arranged, a lighting lamp can be additionally arranged at a position close to the filter screen 5 inside the roasting machine to facilitate observation.
