[0058] Please refer to Figures 1 to 18 A specific implementation of a steamer according to an embodiment of the present invention is shown.

[0059] like Figure 1 and Figure 2 As shown, this embodiment provides a steamer, which may include a steamer housing 10, with a feed inlet 103 and a discharge outlet 103' formed on both sides of the steamer housing 10. A feed roller 201 (such as Fig. 9 ), and a discharging roller 201' opposite to the discharging port 103'. Specifically, a feed box 103a connected to the steamer housing 10 and having a feed port 103 and a discharging box 103'a having a discharging port 103' are formed above both sides of the steamer housing 10. The feed roller 201 is located in the feed box 103a and above the feed port 103, and the discharging roller 201' is located in the discharging box 103'a and above the discharging port 103'. The feed box 103a provided with the feed port 103 is used to allow the fabric 20 to enter the steamer housing 10, and the discharging box 103'a provided with the discharging port 103' is used to allow the fabric 20 to be discharged from the steamer housing 10.

[0060] Multiple transmission sprocket groups for installing two endless chains 102 are arranged in the steamer housing 10. Specifically, four transmission sprocket groups for installing two endless chains 102 are arranged in the steamer housing 10, which are the target transmission sprocket group 101 arranged near the feed port 103, the transmission sprocket group 115 arranged below the target transmission sprocket group 101, the transmission sprocket group 117 arranged near the discharge port 103', and the transmission sprocket group 116 arranged below the transmission sprocket group 117. Each transmission sprocket group is coaxially arranged, and each endless chain 102 is installed on four transmission sprockets located on the same target surface in the four transmission sprocket groups to form two chain transmission paths. Among them, the target surface refers to a plane parallel to the front surface 10a of the steamer housing 10. In addition, the transmission sprocket group 117 arranged near the discharge port 103' is a driving sprocket group, and the target transmission sprocket group 101, the transmission sprocket group 115 and the transmission sprocket group 116 are driven sprocket groups, so that the transmission of the transmission sprocket group 117 drives each driven sprocket group to drive, thereby realizing the circular transmission of the two endless chains 102 arranged on the four transmission sprocket groups. A cloth feeding roller 104 is also arranged in the steamer housing 10 near the feed port 103 and above the target transmission sprocket group 101.

[0061] Combination Figures 2 to 4 For explanation, the steamer of this embodiment includes: a cloth-laying roller 105 horizontally placed between two endless chains 102, with crank assemblies 106 connected to the two endless chains 102 on both sides of the cloth-laying roller 105, so that the cloth-laying roller 105 gradually droops when it is transferred to the position corresponding to the curvature change part, and the curvature change part is the part of the chain formed by the target transmission sprocket group 101 when the endless chain 102 moves along the C direction; a toggle member 107 located above the side of the target transmission sprocket group 101, and a support plate 108 for supporting the gradually drooping cloth-laying roller 105 is arranged below the toggle member 107, and the toggle member 107 is controlled to flip laterally when the drooping height of the fabric 70 reaches a preset value after passing through the cloth feeding roller 104 and entering the steamer housing 10, so as to push the cloth-laying roller 105 on the support plate 108 to above the two endless chains 102 and enable the cloth-laying roller 105 to receive the fabric 70.

[0062] Specifically, continue to Figure 4 To illustrate, the inner side plate of the steamer housing 10 is provided with a track support 1022, the free end of which is connected with a longitudinally extending loop plate 1023, and one side of the track support 1022 is formed with a track 1021 for the ring chain 102 to move. The loop plate 1023 is configured to receive the cloth-laying roller 105 when the toggle member 107 is controlled to flip laterally to push the cloth-laying roller 105 on the support plate 108 upward. Figure 5As shown, the crank assembly 106 is composed of a roller 1061 connected to the end of the cloth-laying roller 105, a movable crank 1062 connected to the roller 1061, and a connecting portion 1063 pivotally connected to the movable crank 1062, and the connecting portion 1063 is connected to the endless chain 102. The connecting portion 1063 is formed with at least one rolling portion 1064 that moves along the track 1021. It is worth noting that when the toggle member 107 flips horizontally to push the cloth-laying roller 105, the movable crank 1062 rotates with the first axis 100 as the axis, so as to drive the cloth-laying roller 105 to rotate along the first axis 100 as the axis through the roller 1061, thereby, the roller 1061 of the crank assembly fixedly connected to the end of the cloth-laying roller 105 is pushed to the top of the ring-forming plate 1023, so that the roller 1061 of the crank assembly is supported by the ring-forming plate 1023 to support the cloth-laying roller 105.

[0063] In this embodiment, the steamer moves the cloth-laying roller 105 to the position corresponding to the curvature change portion through the crank assembly 106 connected to both sides of the cloth-laying roller 105, and gradually droops, and supports the gradually drooping cloth-laying roller 105 through the support plate 108. When the drooping height of the fabric 70 after entering the steamer housing 10 reaches a preset value, the toggle member 107 arranged on the upper side of the target transmission sprocket group 101 is controlled to flip horizontally, so as to push the cloth-laying roller 105 on the support plate 108 to the top of the two ring chains 102 through the lateral flipping of the toggle member 107, so that the cloth-laying roller 105 can bear and form a ring-shaped fabric. It can be seen that the looping mechanism of this embodiment can be timely flipped horizontally according to the drooping height of the fabric after entering the steamer housing 10 by the toggle member 107, which can not only effectively realize the automatic looping of the fabric to save the structural space in the steamer, but also ensure the neatness of the fabric looping, improve the effect of the fabric looping, and ensure the uniformity of the fabric steaming.

[0064] Reference Figures 1 to 3 For explanation, the steamer of this embodiment also includes: a loop-forming fan 109, which is formed with a blowing duct 110 located above the cloth-laying roller 105, and the air outlet of the blowing duct 110 is directly facing the fabric between the cloth-feeding roller 104 and the target cloth-laying roller; wherein the target cloth-laying roller is configured to be pushed to the first cloth-laying roller on the two ring chains by the toggle member 107.

[0065] It should be understood that after the cloth feeding roller 104 conveys the fabric 70 to the steamer housing 10, due to the support of the target cloth-resting roller and the cloth feeding roller 104, the fabric 70 suspended between the cloth feeding roller 104 and the target cloth-resting roller is directly opposite to the air outlet of the blowing duct 110, and the airflow generated by the working of the ring-forming fan 109 blows toward the fabric suspended between the cloth feeding roller 104 and the target cloth-resting roller through the blowing duct 110, not only making the fabric gradually ring-shaped, but also making the fabric between the cloth feeding roller 104 and the target cloth-resting roller gradually droop, so that the toggle member 107 flips when the drooping height reaches a preset value. Among them, the preset value can be set according to the actual working condition requirements of the steamer, and its specific value is a technology well known to those skilled in the art, and will not be described in detail.

[0066] Continue to refer to Figures 1 to 3 To illustrate, in any of the above embodiments, a support seat 111 is arranged below the support plate 108, one side of the support plate 108 is hinged to the support seat 111, and a longitudinally arranged return spring 112 is arranged between the target position of the support plate 108 and the corresponding position of the support seat 111. Among them, the target position of the support plate 108 is a position close to the free end of the support plate 108 or a position close to the center of the support plate 108. In this way, when the crank assembly 106 moves to the curvature change portion with the ring chain 102, the crank assembly 106 drives the cloth-laying roller 105 to gradually sag along the support plate 108, and the return spring 112 between the support plate 108 and the support seat gradually shrinks under the gravity of the cloth-laying roller 105, until the toggle member 107 flips horizontally to push the cloth-laying roller 105 onto the ring plate 1023, the return spring 112 automatically extends, and the support plate 108 automatically resets to wait for the next cloth-laying roller 105.

[0067] It should be noted that the horizontal cross section of the support plate 108 is configured in an arc shape, and the concave portion of the support plate 108 faces the drooping cloth-laying roller 105, that is, the support plate 108 has a structure with high ends and low middle. Therefore, the configuration structure of the support plate 108 is adapted to the drooping trajectory of the cloth-laying roller 105, so that the toggle member 107 pushes the cloth-laying roller 105 along the arc surface of the support plate 108 onto the ring-forming plate 1023.

[0068] Reference Figures 1 to 3 , Figure 6 to Figure 7As shown, a toggle member 107 is arranged correspondingly on the upper side of each transmission sprocket in the target transmission sprocket group 101, and a toggle shaft 107' is arranged in the steamer housing 10, which passes through the centers of the two toggle members 107 along the target direction, and the two ends of the toggle shaft 107' extend from the front 10a and the back 10b of the steamer housing 10 respectively, and are connected to the front 10a and the back 10b of the steamer housing 10 through the bearing seat 113. Among them, the toggle member 107 may specifically include a finger 1071, a finger shaft cam 1072 and a transmission mechanism 1073, and the finger shaft cam 1072 is connected to a sensor (not shown in the figure) for detecting the sagging height of the fabric after entering the steamer housing 10, so that when the sagging height of the fabric reaches a preset value, the transmission mechanism 1073 controls the finger 1071 to flip horizontally. In addition, a motor 114 connected to the toggle shaft 107' is disposed on the outer front side or the outer back side of the steamer housing 10, so that the toggle shaft 107' is driven to rotate by the motor 114, thereby controlling the transmission mechanism 1073 to drive the toggle claw 1071 to rotate along the direction B. In this way, by the lateral flipping of the toggle member 107 to push the cloth-laying roller 105 hanging down on the support plate 108 to the looping plate 1023, not only can the automatic looping of the fabric be effectively realized to save the structural space in the steamer, but also the neatness of the fabric looping is ensured, the effect of the fabric looping is improved, and the uniformity of the fabric steaming is ensured.

[0069] Combination Figure 1 , Figure 2 , Figures 8 to 11For illustration, the steamer of this embodiment includes: an anti-drip plate 203 which is arranged obliquely above the feed roller 201 and / or the discharge roller 201' and has a preset gap 2031 with the top of the steamer housing 10, that is, the corresponding anti-drip plate 203 can be arranged above both the feed roller 201 and the discharge roller 201', or the anti-drip plate 203 can be arranged above one of the feed roller 201 and the discharge roller 201'. Preferably, the corresponding anti-drip plate 203 is arranged above both the feed roller 201 and the discharge roller 201'. Specifically, the anti-drip plate 203 can be arranged in the feed box 103a and the discharge box 103'a, and has a preset gap 2031 with the top of the steamer housing 10. An oil discharge hole 2032 is formed at the lower end of the anti-drip plate 203. The steamer also includes an oil drain pipe 205 arranged below the oil drain hole 2032 and used to receive the oil smoke and discharge the oil smoke to the outside of the steamer housing 10. The air outlet of the second circulation fan 304 penetrates the drip plate 203, so that the hot air circulation space 200 is formed on the upper side of the drip plate 203, so that the gas flowing from the air outlet to the hot air circulation space 200 flows from the preset gap 2031 to the steamer housing 10. Specifically, the second circulation fan 304 is formed with two bifurcated air ducts (i.e., branch pipes 305') that are attached to the corresponding inner wall 10' of the steamer housing 10, and the air outlet ends of the two air ducts (i.e., branch pipes 305') penetrate the drip plate 203, so that the gas in the air duct (i.e., branch pipes 305') flows from the air outlet to the hot air circulation space 200 along the D direction, and flows from the preset gap 2031 to the steamer housing 10 along the D' direction. The air (the air temperature is lower than the gas temperature in the steamer housing 10) entering the steamer housing 10 from the feed port 103 can reduce the temperature in the steamer housing 10 to improve the steaming quality of the fabric in the steamer housing 10. The cleaning steam pipe 204 is arranged in the hot air circulation space 200 above the side of the anti-drip plate 203, so as to clean the anti-drip plate 203 and the oil drain pipe 205 located below, so as not to affect the steaming quality of the fabric.

[0070] It should be understood that the steamer of this embodiment is provided with a drip plate 203 with a preset gap 2031 formed with the top of the steamer housing, so that the oil smoke generated in the steamer housing 10 slides along the inclination direction of the drip plate 203 to the oil drain hole 2032 formed at the lower end of the drip plate 203, and drips along the oil drain hole 2032 to the oil drain pipe 205 located below the oil drain hole 2032, so that the oil smoke is discharged from the steamer housing 10 through the oil drain pipe 205. In addition, since the air outlet end of the second circulation fan 304 passes through the drip plate 203, a hot air circulation space 200 is formed on the upper side of the drip plate 203, so that the gas generated by the second circulation fan is not affected to flow from the preset gap 2031 into the steamer housing 10 to dry the fabric. It can be seen that the steamer of this embodiment can timely discharge the oil smoke generated during the operation of the steamer without affecting the second circulation fan circulating the gas in the steamer housing, so as to improve the production quality of the fabric.

[0071] The two sides of the anti-drip plate 203 are fitted with the inner wall of the steamer housing 10, the top of the anti-drip plate 203 is in contact with the inner side wall of the steamer housing 10, and the free end of the anti-drip plate 203 opposite to the top of the anti-drip plate forms a preset gap 2031 with the top of the steamer housing 10. Specifically, the two sides of the anti-drip plate 203 are fitted with the inner wall of the feed box 103a or the discharge box 103'a, the top of the anti-drip plate 203 is in contact with the inner side wall of the feed box 103a or the discharge box 103'a, and the free end of the anti-drip plate 203 forms a preset gap 2031 with the top of the steamer housing 10.

[0072] The top of the anti-drip plate 203 is lower than the free end of the anti-drip plate 203, and an oil drain hole 2032 is formed at the top of the anti-drip plate 203. Further, the anti-drip plate 203 has a plurality of oil drain holes 2032 evenly arranged along its length, and the inlet of the oil drain pipe 205 faces the plurality of oil drain holes 2032. The oil drain pipe 205 is attached to or close to the inner side wall of the steamer housing 10 and extends to the feed port 103 or the discharge port 103' of the steamer housing 10, and extends out from the feed port 103 or the discharge port 103'. For the steamer housing 10 formed with the feed box 103a and the discharge box 103'a, the oil drain pipe 205 arranged at the feed box 103a is attached to or close to the inner side wall of the feed box 103a and extends to the feed port 103 so as to extend out from the feed port 103, and the oil drain pipe 205 arranged at the discharge box 103'a is attached to or close to the inner side wall of the discharge box 103'a and extends to the discharge port 103' so as to extend out from the discharge port 103'. Such a configuration facilitates the oil smoke falling on the anti-drip plate 203 in the steamer housing 10 to slide to the top of the anti-drip plate 203 under the action of gravity, and drips into the oil drain pipe 205 located below the oil drain hole 2032 through the oil drain hole 2032 formed at the top of the anti-drip plate, so as to discharge the oil smoke out of the steamer housing. The feed box 103a and the discharge box 103'a may both be provided with an oil discharge outlet 2051, and the oil discharge outlet of the oil discharge pipe 205 is directly opposite to the oil discharge outlet 2051, so as to replace the oil discharge pipe 205 extending from the feed port 103 or the discharge port 103' of the steamer housing 10.

[0073] It is worth noting that the drip plate 203 forms an acute angle α with the horizontal axis 200a of the steamer housing 10, or the drip plate 203 forms an acute angle α with a straight line 200a' parallel to the horizontal axis 200a, and the drip plate 203 is perpendicular to the inner wall of the front 10a and the inner wall of the back 10b of the steamer housing 10. The value range of the acute angle α can be 30 to 75 degrees, preferably, the value range of the acute angle α can be 35 to 60 degrees. Further preferably, the value range of the acute angle α can be 40 to 45 degrees. Thus, by setting the acute angle α, the oil smoke generated in the steamer housing 10 falls on the anti-drip plate 203, slides along the inclined surface of the anti-drip plate 203 to the top of the anti-drip plate 203, and drips into the oil drain pipe 205 located below the oil drain hole 2032 through the oil drain hole 2032 formed at the top of the anti-drip plate, so as to improve the sliding effect of the oil smoke dripping on the anti-drip plate 203. It should be noted that the value of the acute angle α can be set according to the specific actual working conditions, and is not limited to the range defined in this embodiment.

[0074] Combination Figure 1 , Fig.12To illustrate, the steamer also includes: a heat circulation ventilation pipeline 301 arranged at the bottom of the steamer housing 10, a plurality of first circulation fans 302 are arranged above the heat circulation ventilation pipeline 301, and the plurality of first circulation fans 302 are all formed with a first air duct pipeline 303 connected to the heat circulation ventilation pipeline 301; second circulation fans 304 are arranged on both sides of the steamer housing 10, and the second circulation fans 304 are formed with a second air duct pipeline 305 connected to the heat circulation ventilation pipeline 301; a combustion furnace 50 connected to the steamer housing 10, and the combustion furnace 50 is respectively connected to the first air duct pipeline 303 and the heat circulation ventilation pipeline 301 in the steamer housing 10. Among them, the air inlet end 501 of the combustion furnace 50 is connected to the steamer housing 10, and the air outlet end 502 of the combustion furnace 50 is connected to the heat circulation ventilation pipeline 301. The target side of the vaporizer housing 10 is provided with an air inlet 502' connected to the air outlet end 502 of the combustion furnace 50, and an air outlet 501' connected to the air inlet end 501 of the combustion furnace 50. The vertical height of the air inlet 502' on the target side of the vaporizer housing 10 is generally lower than the vertical height of the air outlet 501'. The target side of the vaporizer housing 10 may be the front side 10a or the back side 10b of the vaporizer housing 10.

[0075] Specifically, the first air duct 303 is arranged closely to the inner wall of the front side 10a and the inner wall of the back side 10b of the steamer housing 10, and the first air duct 303 is formed with two branch ducts 303' extending longitudinally to the top of the steamer housing and having a preset distance d1 from the top of the steamer housing. The first circulation fan 302 forms an airflow H flowing from bottom to top along the first air duct 303 into the steamer housing 10. The airflow H forms a branch airflow H1 and a branch airflow H2 through the two branch ducts 303' to flow into the steamer housing 10. The second air duct 305 is arranged closely to the inner wall of the side of the steamer housing 10, and the second air duct 305 is formed with two branch ducts 305' extending longitudinally to the top of the steamer housing and having a preset gap 2031 from the top of the steamer housing. The second circulation fan 304 generates an airflow M from bottom to top and flows into the steamer housing 10 along the second air duct 305. The airflow M is sequentially formed into an airflow M1 and an airflow M2 through two branch pipes 305' to flow into the steamer housing 10.

[0076] The first air duct 303 has a first opening 3031, and the heat circulation ventilation duct 301 is connected to the first air duct 303 through the first opening 3031. The second air duct 305 has a second opening 3051, and the heat circulation ventilation duct 301 is connected to the second air duct 305 through the second opening 3051.

[0077] It should be noted that the size of the preset gap 2031 formed between the air outlet ends of the two branch pipes 305' of the second air duct 305 and the top of the steamer housing can be set to ensure that the gas flowing out of the two branch pipes 305' can effectively flow into the steamer housing 10. The specific size can be set according to the actual working conditions, and no detailed description is given for this. The preset distance d1 formed between the air outlet ends of the two branch pipes 303' of the first air duct 303 and the top of the steamer can be set according to the actual working conditions, as long as it can ensure that the gas flowing out of the two branch pipes 303' can effectively flow into the steamer housing 10. No detailed description is given for this. Among them, the air outlet ends of the two branch pipes 305' are generally higher than the air outlet ends of the two branch pipes 303'.

[0078] It can be understood that the hot gas N1 generated by the combustion furnace 50 flows into the air inlet 502' of the vaporizer housing 10 through its air outlet 502 to flow into the heat cycle ventilation pipeline 301, and the hot gas N1 flowing into the heat cycle ventilation pipeline 301 flows into the first air duct pipeline 303 through the first open port 3031, and the gas H flowing into the first air duct pipeline 303 forms a branch airflow H1 and a branch airflow H2 through two branch pipes 303' to flow into the vaporizer housing 10. At the same time, the hot gas N1 in the heat cycle ventilation pipeline 301 flows into the second air duct pipeline 305 through the second open port 3051, and the gas M in the second air duct pipeline 305 forms a branch airflow M1 and a branch airflow M2 through two branch pipes 305' to flow into the vaporizer housing 10. Thus, the gas N2 flowing into the vaporizer housing 10 through the first air duct 303 and the second air duct 305 flows into the combustion furnace 50 .

[0079] As can be seen, the heat circulation supply system of this embodiment is connected to the first air duct 303 and the heat circulation ventilation duct 301 in the steamer housing 10, respectively, and the combustion furnace 50 provides circulating hot air to the steamer, and the multiple groups of first circulation fans 302 arranged above the heat circulation ventilation duct 301 disperse the hot air provided by the combustion furnace into the steamer housing 10 through the first air duct 303, and the second circulation fans 304 arranged on both sides of the steamer housing 10 disperse the hot air into the steamer housing 10 through the second air duct 305. In this way, the heat circulation supply system can effectively heat the fabric in the steamer housing, thereby effectively improving the effect of steaming the fabric in the steamer housing, and it does not need to consume too much electric energy to reduce the consumption of electric energy.

[0080] In this embodiment, combined with Figure 1 and Fig.13For illustration, the front 10a outer wall and the back 10b outer wall of the steamer housing 10 are both provided with an oil exhaust fan 306, and the oil exhaust fan 306 extracts the oil smoke in the steamer housing 10 in the R1 direction and discharges it outside the steamer housing 10 in the R2 direction. The oil exhaust fan 306 can be configured as two, and the two oil exhaust fans are respectively close to the feed box 103a and the discharge box 103'a of the steamer housing. The oil exhaust fan 306 can be configured as multiple, and the multiple oil exhaust fans are evenly arranged in the length direction of the steamer housing 10. Of course, the number of the oil exhaust fans 306 can be configured according to the actual working conditions, and is not limited to the scope defined in this embodiment.

[0081] In any of the above embodiments, Figures 14 to 16 To explain, the combustion furnace 50 includes a combustion chamber shell 500, in which a combustion tube 503 is arranged along a first direction to fit the inner side of the combustion chamber shell 500, specifically, the bottom of the combustion tube 503 fits the inner side of the combustion chamber shell 500. The combustion chamber shell 500 is penetrated along the first direction to extend into the combustion tube 503, so that a flame 5041 is generated in the combustion tube 503 by igniting the burner 504. The free end 5031 of the combustion tube 503 is directly opposite to the blades of the third circulation fan 505. Among them, a blocking plate 506 is arranged between the free end 5031 of the combustion tube 503 and the third circulation fan 505, which is used to change the flow direction of the hot gas from the combustion tube 503 to the combustion chamber 500'.

[0082] It should be understood that the combustion furnace 50 ignites the burner 504 so that the hot gas of the flame generated in the combustion tube 503 is emitted into the combustion chamber 500'. Since a blocking plate 506 is arranged between the free end 5031 of the combustion tube 503 and the third circulation fan 505, the hot gas emitted from the combustion tube 503 is blocked by the blocking plate 506 and flows along the outer direction of the blocking plate 506 to the air duct 5051 of the third circulation fan 505, so as to avoid the hot gas emitted from the combustion tube 503 directly flowing to the blades of the third circulation fan 505 and causing damage to the blades. In this way, this embodiment can solve the problem of the hot gas emitted from the combustion chamber burning the circulation fan blades in the prior art.

[0083] Furthermore, the first direction cross section of the blocking plate 506 is configured as a triangle, and the triangular top of the blocking plate 506 is arranged opposite to the free end 5031 of the combustion tube 503. In this way, the hot air emitted from the combustion tube 503 flows along the triangular inclined surface of the blocking plate 506, i.e., in the direction P toward the air duct 5051 of the third circulation fan 505, so as to prevent the hot air from directly flowing to the blades of the third circulation fan 505 and causing damage to the blades.

[0084] Specifically, the blades of the third circulation fan 505 are connected to a connecting shaft 507 that penetrates the combustion chamber housing 500 along the first direction, and the connecting shaft 507 is arranged on a bearing seat 508 located outside the combustion chamber housing 500, and a base 509 is arranged at the end of the bearing seat 508, and a driving motor 510 for driving the blades to rotate is arranged on the base 509. Thus, the driving motor 510 drives the third circulation fan 505 to operate, so as to blow the hot gas N1 in the combustion chamber 500' into the heat circulation ventilation pipeline 301 at the bottom of the vaporizer housing 10, and then radiate it into the vaporizer housing 10 through two branch pipelines 303' and two branch pipelines 305' in sequence, and the gas N2 in the vaporizer housing 10 flows into the combustion furnace 50, so as to supply the hot circulation gas to the vaporizer housing in the next step.

[0085] The side wall of the combustion tube 503 is evenly arranged with a plurality of air outlet holes 5032 for heat supply gas to flow into the combustion chamber 500'. The air inlet end 501 of the combustion chamber shell 500 is directly opposite to the side wall of the combustion tube 503, and the air outlet end 502 of the combustion chamber shell 500 is connected to the air duct 5051 of the third circulation fan 505. In this way, after the hot air in the combustion tube 503 flows out through the plurality of air outlet holes 5032, it can be mixed with the gas N2 entering the combustion chamber 500' from the air inlet end 501, so that the hot air flowing out of the plurality of air outlet holes 5032 can be cooled by the gas N2, so that when the cooled hot air flows to the third circulation fan 505, the blades of the third circulation fan 505 will not be burned, so as to achieve the purpose of further protecting the blades of the third circulation fan 505.

[0086] In addition, the combustion chamber housing 500 is provided with an inspection hole 511 , so that maintenance personnel can repair various components in the combustion chamber 500 ′ (such as the combustion tube 503 , the third circulation fan 505 , the baffle plate 506 , etc.) through the inspection hole 511 , so as to increase the service life of the combustion furnace 50 .

[0087] Combination Figure 1 , Figure 2 , Figure 17 to Figure 18 To illustrate, each of the four transmission sprocket groups in the steamer housing of this embodiment is connected through a transmission shaft assembly. The transmission shaft assembly includes: a transmission shaft 40 that transversely penetrates the transmission sprocket group (target transmission sprocket group 101, transmission sprocket group 115, transmission sprocket group 116, and transmission sprocket group 117) located in the steamer housing 10 and extends to the inner wall of the steamer housing 10. Among them, the target transmission sprocket group 101 is used as an example for illustration, and the target transmission sprocket group 101 has a transmission sprocket 101a and a transmission sprocket 101b. Since the structures of the four transmission sprocket groups are the same, for the convenience of description, this embodiment is described by taking the transmission sprocket group 101 as an example.

[0088] One of the transmission sprockets 101a of the target transmission sprocket assembly 101 is embedded with a tightening sleeve 401 sleeved on the transmission shaft 40, and a first key pin 402 is arranged between the other transmission sprocket 101b and the transmission shaft 40. Among them, the end of the transmission shaft 40 is sleeved with a first bearing seat 403, the first bearing seat 403 penetrates the side wall of the steamer housing 10 and extends to the outside of the steamer housing 10, and the transmission shaft 40 is sleeved with a second bearing seat 404 at a position close to the top end opposite to the end, and the second bearing seat 404 penetrates the side wall of the steamer housing 10 and extends to the outside of the steamer housing 10. Specifically, the side wall of the transmission shaft 40 is formed with a first key groove 402' for installing the first key pin 402, and the tightening sleeve 401 is embedded in the central shaft hole of one of the transmission sprockets 101a and fits with the inner wall of the central shaft hole.

[0089] It can be understood that the transmission shaft assembly of this embodiment passes through the target transmission sprocket set 101 horizontally through the transmission shaft 40. Since the transmission shaft 40 passes through the expansion sleeve 401 embedded in one of the transmission sprockets 101a, the transmission shaft 40 can be connected to the transmission sprocket 101a, and a first key pin 402 is arranged between the transmission shaft 40 and the other transmission sprocket 101b, so that the position between the transmission shaft 40 and the transmission sprocket 101b cannot be changed. In this way, after the transmission shaft 40 passes through the target transmission sprocket set 101 and extends outside the steamer housing 10, the position of the transmission shaft 40 is circumferentially adjusted through the expansion sleeve 401 between the transmission shaft 40 and one of the transmission sprockets 101a to ensure that the positions of the two transmission sprockets of the target transmission sprocket set 101 correspond to each other, avoiding the problem that the positions of the two transmission sprockets do not correspond to each other due to the circumferential error caused by processing at the position where the transmission shaft 40 is connected to the two transmission sprockets, thereby making the motion trajectories of the two ends of the cloth-laying roller asynchronous. Therefore, the cloth-laying roller drives the fabric to move neatly and regularly in the steaming machine housing, thereby improving the steaming effect of the fabric.

[0090] It should be noted that the circumferential direction involved in this embodiment refers to the annular direction along the side wall of the transmission shaft 40 with the axis 400 of the transmission shaft 40 as the axis.

[0091] In the above further embodiment, the first bearing seat 403 and the second bearing seat 404 are both embedded with sleeves 405 respectively fitting with the bottom of the corresponding bearing seat and sleeved on the transmission shaft 40, and the position corresponding to the sleeve 405 in the transmission shaft 40 is formed with a second keyway 406' for installing the second key pin 406. The outer wall of the sleeve 405 and the inner side wall of the first bearing seat 403 and the second bearing seat 404 are respectively provided with retaining rings 411. Among them, the end of the transmission shaft 40 is embedded in the first bearing seat 403, and the top of the transmission shaft 40 passes through the bottom of the second bearing seat 404. The outer bottom end surface of the first bearing seat 403 is covered with a pressure plate 407, and the outer bottom end surface of the first bearing seat 403 is covered with a pressure plate 407, and the pressure plate 407 is provided with a bolt 407', and the bolt 407' passes through the first bearing seat 403 and extends to the end of the transmission shaft 40.

[0092] The first bearing seat 403 and the second bearing seat 404 are both embedded with bearings 408 sleeved on the transmission shaft 40, and sealing rings 409 are arranged between the first bearing seat 403 and the second bearing seat 404 and the side wall of the transmission shaft 40. At least one oil receiving pipe 410 for adding lubricating medium is formed on the outer side of the first bearing seat 403 and the second bearing seat 404 to ensure the normal operation of the bearings in the first bearing seat 403 or the second bearing seat 404.

[0093] In addition, the top end of the transmission shaft 40 passes through the side wall of the steamer housing 10 and extends outside the steamer housing 10 and is connected to a motor (not shown in the figure). The connection method between the motor and the transmission shaft 40 and the driving process or driving method of the motor driving the transmission shaft 40 are all technologies well known to those skilled in the art and will not be described in detail.

[0094] It should be noted that the transverse direction in this embodiment refers to the x-axis direction, the longitudinal or vertical direction refers to the y-axis direction, and the target direction or first direction refers to the z-direction. In addition, the inner wall of the steamer housing 10 in this embodiment is made of heat-insulating material.

They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
