Description

Technical Field

[0001] This application relates to the field of fabric printing and dyeing technology, specifically to a filter inspection door structure for a baking machine and a baking machine. Background Technology

[0002] A baking machine is a type of equipment used for high-temperature treatment of polyester fabrics for hot melt dyeing with disperse dyes, anti-wrinkle and anti-shrink finishing of fiber fabrics, water repellency, stain resistance, flame retardancy and other related finishing processes. It is usually composed of a flat fabric feeding device, a pre-drying machine, a heating device and a heat transfer medium circulation pipeline system, a cooling device, a transmission mechanism and a fabric discharge device, etc., and uses high-temperature air or flue gas as the heating medium.

[0003] The existing baking machine's filter is located inside the machine. The filter primarily filters dust and other impurities from the air to prevent fabric contamination. During maintenance, the access door needs to be opened to enter the baking machine for filter removal and replacement. Due to the 200-degree Celsius environment inside the baking machine, burns are a risk during maintenance. Therefore, maintenance typically requires waiting for the machine to cool to a suitable temperature, which prolongs maintenance time and makes restarting the machine time-consuming, hindering production. Therefore, the filter structure needs to be improved to allow operators to move the filter from outside the casing. This requires an additional access door on the casing. However, due to the high temperature inside the baking machine, opening the access door can cause hot gases to escape and burn maintenance personnel. Utility Model Content

[0004] This application provides a filter inspection door structure for a baking machine and a baking machine. By designing the inspection door, the high-temperature gas inside the baking machine can basically overflow in a preset direction when the inspection door is opened, thereby solving the problem that high-temperature gas easily overflows in all directions when the inspection door is opened, causing burns to maintenance personnel.

[0005] This application is achieved through the following technical solution:

[0006] In a first aspect, this application provides a maintenance door structure for a baking machine filter, comprising:

[0007] The maintenance door body is equipped with a door handle and is rotatably connected to the baking machine housing to close the maintenance opening on the housing.

[0008] Two flexible corrugated plates are respectively connected to both ends of the width direction of one of the plates of the inspection door body, and magnetic strips for adsorbing the shell are provided on the flexible corrugated plates.

[0009] The baking machine filter access door structure and baking machine provided in this application, through the setting of elastic corrugated plates, ensure that after the access door body is rotated open to a certain angle, the access door body will not detach from the shell due to the elastic extension of the elastic corrugated plates and the magnetic attraction of the magnetic strip. The gap between one end of the access door body in the length direction and the shell is greater than the gap between the other end and the shell, while the two ends of the access door body in the width direction are connected to the shell through elastic corrugated plates. Thus, the high-temperature gas in the baking machine basically overflows from one end of the access door body in the length direction. In the working state, this end can be configured vertically upward, thereby greatly reducing the probability of high-temperature gas causing burns to maintenance personnel. After continuing to rotate the access door body, the magnetic strip can be disengaged from the shell, thereby realizing the complete opening of the access door body, which facilitates the replacement and maintenance of the filter.

[0010] In some alternative embodiments, a sealing layer is provided on the side of the access door body.

[0011] In some alternative embodiments, the side of the access door body is configured as a wedge.

[0012] In some alternative embodiments, the door handle is connected to the access door body via an insulation layer.

[0013] In some alternative embodiments, the surface of the access door body connected to the resilient corrugated plate is configured as an arc-shaped surface.

[0014] In some alternative embodiments, a bolt mechanism is also included, the bolt mechanism having a first engaging component and a second engaging component, wherein the first engaging component is connected to the access door body, and the second engaging component is used to connect to the housing of the baking machine.

[0015] In some alternative embodiments, the first engaging component is configured as an L-shaped plate, with one end of the first engaging component connected to the plate surface of the access door body to form an engaging cavity with the access door body;

[0016] The second card engagement component includes:

[0017] A connecting post for connecting to the housing of the baking machine;

[0018] A locking rod is rotatably connected to the connecting column, and the locking rod can enter the locking cavity during rotation.

[0019] In some optional embodiments, the engaging rod is elastically rotatably connected to the connecting post, and the connecting post is further provided with a limit post to restrict the rotation of the engaging rod;

[0020] When the engaging rod contacts the limiting post, the engaging rod is located in the engaging cavity.

[0021] In some alternative embodiments, one end of the locking rod is connected to a reinforcing rod, and one end of the reinforcing rod is used to contact the housing of the baking machine;

[0022] In the working state, the first engaging component and the reinforcing rod are located on both sides of the second engaging component.

[0023] Secondly, this application provides a baking machine, including a housing and any of the baking machine filter access door structures described in the first aspect;

[0024] The housing is provided with a countersunk hole to form an inspection port;

[0025] One end of the inspection door body along its length is rotatably connected to the inspection opening, and a magnetic adsorption part is provided on the stepped surface inside the inspection opening for magnetic strips to be adsorbed.

[0026] Compared with the prior art, this application has the following advantages and beneficial effects:

[0027] The oven filter access door structure provided in this application, through the setting of elastic corrugated plates, ensures that after the access door body is rotated open to a certain angle, it will not detach from the housing due to the elastic extension of the elastic corrugated plates and the magnetic attraction of the magnetic strip. The gap between one end of the access door body and the housing in the length direction is greater than the gap between the other end and the housing, while both ends of the access door body in the width direction are connected to the housing through elastic corrugated plates. Thus, the high-temperature gas inside the oven basically overflows from one end of the access door body in the length direction. In the working state, this end can be configured vertically upward, thereby greatly reducing the probability of burns to maintenance personnel caused by high-temperature gas. Continuing to rotate the access door body allows the magnetic strip to detach from the housing, thereby enabling the access door body to be fully opened, which facilitates the replacement and maintenance of the filter.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0038] like Figures 1-2 As shown, in a first aspect, this application provides a baking machine filter maintenance door structure, including a maintenance door body 1 and an elastic corrugated plate 2; the maintenance door body 1 is provided with a door handle 4, and the maintenance door body 1 is rotatably connected to the baking machine housing 6 to close the maintenance opening 61 on the housing 6; two elastic corrugated plates 2 are respectively connected to the two ends in the width direction of one of the plates of the maintenance door body 1, and the elastic corrugated plates 2 are provided with magnetic strips 3 for adsorbing the housing 6.

[0039] In this embodiment, the inspection door body 1 is generally rectangular in shape, and two pivots 5 can extend from one end of the inspection door body 1 in the length direction to both sides in the width direction so as to be rotatably connected to the housing 6 of the baking machine.

[0040] After the inspection door body 1 rotates a certain angle on the shell 6 of the baking machine, due to the setting of the elastic corrugated plate 2 and the magnetic strip 3, the two sides of the inspection door body 1 in the width direction will not detach from the shell 6. That is, after the high-temperature gas inside the baking machine impacts the plate surface of the inspection door body 1, it will not overflow to the two sides of the width direction of the inspection door body 1. Furthermore, since the inspection door body 1 is opened by rotation, the rotation radii at both ends of the length direction of the inspection door body 1 are different. The gap between one end of the inspection door body 1 in the length direction and the shell 6 is different from the gap between the other end of the inspection door body 1 in the length direction and the shell 6. Therefore, after the inspection door is opened, the high-temperature gas inside the baking machine will overflow from one end of the length direction of the inspection door body 1. In specific implementation... With this end installed at the top, combined with the characteristic of hot air rising, the high-temperature gas inside the baking machine basically overflows from the top of the inspection door body 1, greatly reducing the probability of maintenance personnel being burned. Continuing to rotate the inspection door body 1, the elastic corrugated plate 2 reaches its limit of elastic deformation. At this point, the inspection door body 1, through the elastic corrugated plate 2, pulls the magnetic strip, causing the magnetic strip to detach from the housing 6, thus allowing the inspection door body 1 to be fully opened, facilitating filter replacement. After the filter is replaced, the inspection door body 1 is rotated in the opposite direction to allow the magnetic strip 3 to re-attach to the housing 6. Under the elastic action of the elastic corrugated plate 2, the inspection door body 1 can adhere to the housing 6 to prevent the high-temperature gas inside the baking machine from leaking out.

[0041] In the above description, under working conditions, the elastic corrugated plate 2 does not necessarily need to reach the limit of elastic deformation. Instead, by configuring the elastic coefficient of the elastic corrugated plate 2, the force required for the elastic corrugated plate 2 to elastically deform to a certain extent is greater than the magnetic attraction force between the magnetic strip 3 and the housing 6. In this way, when the inspection door body 1 rotates at a certain angle and then the force is applied to rotate it, the magnetic strip 3 can be disengaged from the housing 6, and the elastic corrugated plate 2 does not need to reach the limit of elastic deformation. The advantage of doing so is that it can prevent the elastic corrugated plate 2 from frequently being in the state of elastic deformation limit and thus losing elasticity.

[0042] After the inspection door body 1 is closed, in order to ensure the sealing between the inspection door body 1 and the housing 6, in some optional embodiments, a sealing layer is provided on the side of the inspection door body 1; in actual implementation, the sealing layer can be set as a glass fiber layer to adapt to the high temperature environment of the baking machine and prevent the sealing layer from deforming under high temperature environment and affecting the sealing performance.

[0043] In this embodiment, the elastic corrugated plate 2 can be made of thin steel sheet. In other embodiments, the elastic corrugated plate 2 can also be replaced by a spring and a curtain, that is, the magnetic strip 3 is connected to the access door body 1 by a spring, and the magnetic strip 3 and the access door body 1 are also connected by a curtain to prevent high-temperature gas from leaking from between the magnetic strip 3 and the access door body 1.

[0044] In some optional embodiments, the side of the access door body 1 is configured as a wedge surface; in actual implementation, the housing 6 of the baking machine is also provided with a wedge surface adapted to the side of the access door body 1. The access door body 1 and the housing 6 achieve a seal through wedge surface contact, which can provide a better sealing effect.

[0045] The ambient temperature inside the baking machine is high, and the temperature of the access door body 1 is also usually high. To prevent burns to maintenance personnel when opening the access door body 1, in some optional embodiments, such as... Figure 6 As shown, the door handle 4 is connected to the access door body 1 via the heat insulation layer 8; in actual implementation, the door handle 4 can be connected to the access door body 1 via a ceramic fiber board. In other embodiments, a protective sleeve can be fitted onto the door handle 4.

[0046] In some alternative embodiments, the surface of the access door body 1 connected to the resilient corrugated plate 2 is configured as an arc-shaped surface.

[0047] In this embodiment, the arc-shaped surface can guide the high-temperature gas inside the baking machine, and can prevent the high-temperature gas from causing a large frontal impact on the inspection door body 1, thus preventing the inspection door body 1 from vibrating.

[0048] In some alternative embodiments, see [reference]. Figure 4 and Figure 5 The oven filter inspection door structure also includes a door bolt mechanism 7, which has a first engaging component 71 and a second engaging component. The first engaging component 71 is connected to the inspection door body 1, and the second engaging component is used to connect to the oven housing 6.

[0049] In this embodiment, after the second engaging component engages with the first engaging component 71, the second engaging component contacts the maintenance door body 1. Through the setting of the door bolt mechanism 7, the maintenance door body 1 can be rotated and limited, preventing the maintenance door body 1 from being opened accidentally and causing a safety accident.

[0050] Specifically, in some optional embodiments, the first engaging component 71 is configured as an L-shaped plate. One end of the first engaging component 71 is connected to the plate surface of the access door body 1 to form an engaging cavity with the access door body 1. That is, one plate segment of the first engaging component 71 is connected to the plate surface of the access door body 1, and there is a gap between the other plate segment and the plate surface of the access door body 1. This gap serves as the engaging cavity. The second engaging component includes a connecting post 72 and an engaging rod 74. The connecting post 72 is used to connect the housing 6 of the baking machine. The engaging rod 74 is rotatably connected to the connecting post 72. The length direction of the engaging rod 74 is perpendicular to the length direction of the connecting post 72. The engaging rod 74 can enter the engaging cavity during rotation. In the working state, the engaging rod 74 enters the engaging cavity in a top-to-bottom direction.

[0051] In some optional embodiments, the locking rod 74 can be elastically rotatably connected to the connecting post 72 using a torsion spring. The locking rod 74 can be held within the locking cavity under elastic action, thus preventing it from disengaging from the cavity due to vibrations generated during the operation of the baking machine. A limiting post is also provided on the connecting post 72 to restrict the rotation of the locking rod 74. Correspondingly, a corresponding annular limiting groove can be provided on the locking rod 74 to cooperate with the limiting post. The central angle of the annular limiting groove is at least greater than 90 degrees, meaning the locking rod 74 can rotate to a position where its length is parallel to the length of the inspection door body 1. When the locking rod 74 contacts the limiting post, it is located within the locking cavity. When the inspection door body 1 is opened, the maintenance personnel apply force to the locking rod 74 to overcome the elastic action between the locking rod 74 and the connecting post 72, thereby rotating the locking rod 74 and disengaging it from the locking cavity.

[0052] In some optional embodiments, one end of the locking rod 74 is connected to a reinforcing rod 73, and one end of the reinforcing rod 73 is used to contact the housing 6 of the baking machine. A bullseye can be connected to the end of the reinforcing rod 73 to contact the housing 6 to ensure that the sliding of the reinforcing rod 73 on the housing 6 is relatively smooth. In actual implementation, the reinforcing rod 73 is vertically connected to the locking rod 74. The housing 6 is provided with a receiving groove for the installation of the connecting column 72 and an annular sliding groove for the rotation of the reinforcing rod 73. In this way, after the locking rod 74 is installed, it can be closer to the housing 6 or directly contact the housing 6, that is, the locking rod 74 can be closer to the inspection door body 1 or directly contact the inspection door body 1. In the working state, the first locking assembly 71 and the reinforcing rod 73 are respectively located on both sides of the second locking assembly.

[0053] In this embodiment, the reinforcing rod 73 can offset part of the torque applied by the inspection door body 1 to the locking rod 74, thereby preventing the locking rod 74 from breaking or deforming.

[0054] Secondly, this application provides a baking machine, which can be referred to in the following embodiments. Figure 3 and Figure 4The baking machine includes a housing 6 and any of the baking machine filter access door structures of the first aspect; the housing 6 has a countersunk hole to form an access port 61, the countersunk hole is divided into a large diameter section and a small diameter end, the cross-sectional shape of the large diameter section is adapted to the shape of the access door body 1, that is, the cross-sectional shape of the large diameter section is also rectangular. In other embodiments, if the side of the access door body 1 is constructed as a wedge, the edge of the opening of the large diameter section is chamfered to form a wedge, so that when the access door body 1 is closed, the side of the access door body 1 can fit well with the inner wall of the large diameter section; one end of the access door body 1 in the length direction is rotatably connected to the access port 61, and a magnetic adsorption part is provided on the stepped surface inside the access port 61 for magnetic strip 3 to be adsorbed. If the baking machine housing 6 itself can be magnetically adsorbed, the stepped surface serves as the magnetic adsorption part. If the baking machine itself cannot be magnetically adsorbed, then a strip-shaped object such as iron, chromium, or nickel that can be adsorbed by the magnetic strip 3 needs to be attached to the stepped surface.
