Description

Technical Field

[0001] The present application relates to the field of drying technology, and in particular to a carrier device for a tunnel drying machine. Background Art

[0002] Existing clothing is prone to moisture during storage and transportation, and thus it is easy for clothing to mold before being sold. Clothing needs to go through an ironing process during the production process, and after ironing, the clothing will carry a lot of moisture, and then it is easy to mold during the storage of clothing, resulting in the quality of the clothing being unable to be guaranteed. Therefore, the clothing needs to be dried.

[0003] During the drying process, the relative positions of the conveyor line and the dryer are fixed. The larger the direct heating surface of the garment inside the dryer, the better the drying effect. Therefore, the hanging posture of the garment on the conveyor line of the dryer will have a greater impact on the drying effect of the garment. However, due to the limited drying space of the dryer and the continuous drying requirements, the hanging density of the garment on the conveyor line should be considered. A smaller density is more conducive to drying.

[0004] When ready-made clothes are transported on the hanging production line, the hanging density is relatively high due to considerations of work efficiency and transportation efficiency. The hanging production line cannot be directly used as the transportation line of the dryer. Not only can the best drying effect within the effective space of the dryer not be achieved, but overly dense ready-made clothes will also seriously delay the drying efficiency. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present application provides a transport device for a tunnel dryer, which uses a load-bearing self-deflecting hook to hang the finished clothes, and hangs the finished clothes in a deflected posture to enter the drying tunnel of the dryer for drying. While ensuring the drying effect of the finished clothes, the space utilization rate of the dryer can also be guaranteed.

[0016] Furthermore, the distribution speed of the distribution device matches the running speed of the brush, so that the carrier separated and released by the distribution device and the brush can correspond one to one.

[0017] Furthermore, the spacing between the drive chain and the guide rail and the temporary storage rail matches the length of the brush, so that the brush can separate and push the carrier (hanger) thereon.

[0023] Furthermore, a secondary inclined surface is provided at the top angle of the triangular plate, and the slope of the secondary inclined surface is smaller than the slope of the rear inclined surface of the isotope plate, so that after the carrier is unhooked from the deflection hook and passes over the highest point of the isotope plate, it can slide down immediately without generating a secondary mounting connection with the deflection hook.

[0024] Furthermore, a plane is provided at the top corner of the triangular plate and is smoothly connected to the inclined planes on the waists on both sides.

[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0065] In order to solve the above problems, the present application proposes a transport device for a tunnel dryer, see Figure 1-Figure 20 , mainly including an entry device 1, an exit device 2, and a carrier rail 3. A chain 7 that can circulate is arranged in the carrier rail 3. A plurality of self-deflecting deflection hooks 4 with loads are fixed at equal intervals on the lower side of the chain 7; the carrier rail 3 corresponds to the tunnel setting of the dryer, and the entry device 1 and the exit device 2 are arranged on the carrier rails 3 on both sides of the dryer. The front end of the entry device 1 is docked with the distribution device 8, and the rear end of the entry device 1 is matched with the deflection hook 4 for mounting, so that the carrier released by the distribution device 8 can be mounted and combined with the deflection hook 4, so that the load-bearing deflection hook 4 enters the drying tunnel in a deflected posture; the rear end of the exit device 2 is docked with the slide rail 5, and the front end of the exit device 2 is unhooked and matched with the deflection hook 4, so that the deflection hook 4 in the deflected posture is unhooked from the carrier, thereby releasing the carrier to the slide rail 5, and at the same time releasing the load of the deflection hook 4 to restore it to a normal posture.

[0066] The present application is applied to a tunnel-type dryer, where the garments pass through the tunnel of the dryer to achieve drying of the garments; the carrier can be a hanger. When on a hanging production line, the hanging density of the garments is relatively high based on production requirements. If the garments are directly connected to the dryer for drying, it is not conducive to the effective drying of the garments. Therefore, the carrier of the present application is designed as a bridge branch on the production hanging line, which transfers the garments on the hanging production line to the branch of the dryer for drying and then transfers them to the next process.

[0067] Considering the drying efficiency of the dryer and the drying effect of the clothes, the present application adopts a deflection hook 4 to hang the clothes carrier on the branch line of the dryer, so that the posture of the clothes is deflected to expand the direct contact area between the clothes and the hot air flow to prompt the drying effect; adjusting the distribution density of the deflection hook 4 on the carrier rail 3 can fully utilize the limited space inside the dryer to improve the drying efficiency while ensuring that a single piece of clothes is fully dried.

[0068] In the embodiment of the present application, the deflection hook 4 is a load-bearing self-deflecting hook, that is, when the deflection hook 4 is loaded with the above-mentioned carrier and garments, the deflection hook 4 automatically deflects, and the hanging posture of the garments deflects accordingly; when the deflection hook 4 is unloaded, the deflection hook 4 automatically returns to its initial state.

[0069] In the present application, the posture when the deflection hook 4 does not deflect is the normal posture, that is, the deflection angle of the initial state is 0°; the posture when the deflection hook 4 deflects is the deflection posture, and the preferred deflection angle is 45°.

[0070] It can be understood that a deflection of 45° is the limit deflection angle of the deflection hook 4, and the weight reference standard of the load can be the weight of the carrier without carrying clothes; that is, when only one carrier is loaded on the deflection hook 4, the resulting deflection angle is 45°.

[0071] In the present application, the basic transport line of the transport branch of the dryer is the transport rail 3, on which are arranged a carrier input device bridged with the hanging production line and a carrier output device after drying is completed. The carrier input device is an entry device 1, and the carrier output device is an exit device 2. The space between the entry device 1 and the exit device 2 is used to set up the dryer, and the transport track of the transport rail 3 is parallel to the tunnel alignment of the dryer.

[0072] In the embodiment of the present application, the transport rail 3 includes a main rail, a chain 7, and a driving end 34 and a tensioning end 35 respectively arranged at both ends of the main rail. The deflection hook 4 is fixed at equal intervals to the lower side of the chain 7 to form a mounting combination with a connected carrier. The carrier can be in the form of a hanger, and the upper end of the hanger is hung with a hook and the deflection hook 4, and the lower end of the hanger is loaded with clothes.

[0073] The main rail includes a steel section 31 and a channel rail for passing the chain 7. The two channel rails are symmetrically snapped on both sides of the steel section 31. The steel section 31 and the channel rails have the same length. Fastening devices 36 can be set on the upper surfaces of the two channel rails and the steel section 31 for fixation, and the snap-on structures on both sides form a stable main rail structure.

[0074] The channel rail can be specifically divided into a first branch rail 32 and a second branch rail 33. A limited position channel is provided in each of the first branch rail 32 and the second branch rail 33, thereby forming two parallel track spaces, which can form a reciprocating running track in conjunction with the driving end 34 and the tensioning end 35.

[0075] Specifically, the limiting channel is provided with a limiting rib corresponding to the middle roller of the chain 7, so that the chain 7 can be slidably inserted into the limiting channel corresponding to the limiting rib and run in a horizontal posture, such as Figure 5 The lower side of the limiting channel is communicated with the outside world for installing and fixing the deflection hook 4.

[0076] Furthermore, a driving gear is set at the driving end 34 corresponding to the channel rail, and a driven gear is set at the tensioning end 35 corresponding to the channel rail. The chain 7 connected end to end into a ring can be sleeved on the driving gear and the driven gear and form the required transport track along the limiting channel.

[0077] The driving gear is equipped with a driving motor for driving the chain 7. A telescopic tensioning structure is provided between the tensioning end 35 and the main rail for tightening the chain 7.

[0078] The driving gear and the driven gear are respectively arranged horizontally at the two ends of the main rail. The diameters of the driving gear and the driven gear are the same and match the spacing between the limiting channels of the two branch rails, so that the chain 7 does not produce unnecessary friction, jamming, etc. with the ports of the limiting channels during operation.

[0079] In the embodiment of the present application, the driving end 34 is provided with a card sleeve cover to fit on the upper side of the main rail, which can not only fix the drive gear and the drive motor, but also strengthen the structural stability of the end of the main rail. Fig.12 As shown in . One half of the ferrule is covered and fixed on the end of the main rail, and the other half is suspended. The lower side of the suspended ferrule is used to install the driving gear, and the driving motor is placed on the upper side of the ferrule. The driving motor is connected to the driving gear by transmission. The position between the driving end 34 and the main rail is fixed.

[0080] In the embodiment of the present application, the tensioning end 35 is provided with a sliding sleeve, which can also cover and sleeve the upper side of the main rail, and can also strengthen the structural stability of the end of the main rail while fixing the driven gear. Figure 8 , Fig. 9 As shown in . One half of the sliding sleeve is covered on the end of the main rail and slidably fixed, and the other half is suspended in the air. The lower side of the suspended sliding sleeve is used to install the driven gear, and the driven gear and the sliding sleeve are rotatably connected.

[0081] Since the position between the driving end 34 and the main rail is fixed, when installing the chain 7 , a telescopic space is required to complete the installation more conveniently. Therefore, a corresponding tensioning structure can be provided at the tensioning end 35 .

[0082] In the embodiment of the present application, the telescopic tensioning structure is arranged between the sliding sleeve and the steel section 31, and is used to push the sliding sleeve to tighten the chain 7. The telescopic tensioning structure includes a tensioning block 351 and a tensioning bolt 352. The tensioning block 351 is embedded and fixed to the steel section 31 behind the slideway sleeve. The tensioning block 351 is provided with a screw hole facing the slideway sleeve, so that the tensioning bolt 352 can be screwed into the screw hole and abut against the rear end surface of the slideway sleeve. The position of the slideway sleeve on the steel section 31 can be adjusted by rotating the tensioning bolt 352, thereby tightening or loosening the chain 7.

[0083] Furthermore, the slideway sleeve is slidably fixed between the fixed strip 353 and the steel 31. After adjusting the tension of the chain 7, it can be completely fixed so that the sliding sleeve does not slide, and the tensioning effect of the driven gear on the chain 7 is stabilized. When disassembling, the tensioning bolt 352 is rotated to loosen the chain 7.

[0084] In the embodiment of the present application, the deflection hook 4 includes a mounting tube, a mounting hook 43, and a deflection shaft 44. The deflection shaft 44 is coaxially built into the mounting tube, and a deflection notch is provided on the side wall of the mounting tube. The mounting hook 43 includes a deflection tube 431 sleeved on the deflection shaft 44, a hook located on the outside of the mounting tube, and a connecting body 432 that fixes the deflection tube 431 to the hook through the deflection notch. A spring 45 is sleeved on the deflection shaft 44 below the deflection tube 431. The upper and lower end surfaces of the connecting body 432 and the deflection notch are inclined to be annular cross-sections. When the hook is loaded, the deflection tube 431 can compress the spring 45 and rotate downward along the annular cross-section, so that relative deflection is generated between the mounting hook 43 and the mounting tube.

[0085] It should be clear that the length of the upper and lower end faces of the deflection notch is greater than the length of the upper and lower end faces of the connecting body 432, so that there is a sliding deflection space for the connecting body 432 in the deflection notch; the upper end face of the connecting body 432 corresponds to and abuts against the upper end face of the deflection notch, and the lower end face of the connecting body 432 corresponds to and abuts against the lower end face of the deflection notch, so that the connecting body 432 can only rotate and slide up and down when in the deflection notch, thereby realizing the relative deflection between the mounting hook 43 and the mounting tube.

[0086] As another embodiment, the upper and lower end faces of the connector 432 do not abut against the upper and lower end faces of the deflection notch, and the connector 432 will first move straight up and down, and then produce a deflection effect along the inclined annular section, but this form of deflection will cause vibration.

[0087] Based on the structural design of the deflection hook 4 in the present application, when the mounting hook 43 is loaded, the mounting hook 43 automatically deflects; when the mounting hook 43 is unloaded, the mounting hook 43 automatically resets.

[0088] In an embodiment of the present application, the mounting tube includes a fixed tube 41 and a docking tube 42. An upper notch is opened on the lower end ring wall of the fixed tube 41, and a lower notch is opened on the upper end ring wall of the docking tube 42. The fixed tube 41 and the docking tube 42 are aligned and docked and fixed through a deflection shaft 44, so that the upper notch and the lower notch are aligned and docked to form a deflection notch.

[0089] Furthermore, a docking groove is provided on the docking end surface of the remaining structure of the ring wall at the lower end of the fixed tube 41, and a docking rib is correspondingly provided on the docking end surface of the remaining structure of the ring wall at the upper end of the docking tube 42. The ports on both sides of the docking groove are closed, so that after the docking rib is inserted into the docking groove, the axial position between the fixed tube 41 and the docking tube 42 is fixed.

[0090] A fixing block is provided at the lower end of the deflection shaft 44, an axial hole for inserting the deflection shaft 44 is provided at the bottom of the docking cylinder 42, a fixing portion is provided at the upper end of the deflection shaft 44, and a fixing sleeve 412 is provided at the upper end of the fixing cylinder 41 to be fixed to the fixing portion. When the fixing portion at the upper end of the deflection shaft 44 is inserted from the axial hole and fixed to the fixing sleeve 412 of the fixing cylinder 41, the fixing of the lower end of the deflection shaft 44 can lock the alignment and docking relationship between the docking cylinder 42 and the fixing cylinder 41.

[0091] In the embodiment of the present application, the upper and lower ends of the outer wall of the fixing sleeve 412 are provided with teeth, so that the fixing sleeve 412 can stably carry the deflection shaft 44 and fix it to the fixing tube 41. The fixing method between the fixing sleeve 412 and the fixing part can be threaded connection, interference fit, etc.

[0092] In the embodiment of the present application, the upper end face of the deflection notch is an upper annular section 411, and the lower end face is a lower annular section 421. The upper annular section 411 and the lower annular section 421 have the same length and the same circumference ratio; the upper and lower end faces of the connector 432 have the same length and the same circumference ratio, and the circumference ratio of the upper and lower end faces of the deflection notch is greater than the circumference ratio of the upper and lower end faces of the connector 432. Fig.19 As shown in , the proportional value can be adjusted according to the deflection angle actually required.

[0093] In the embodiment of the present application, a gasket is provided between the spring 45 and the deflection tube 431, and the gasket is sleeved on the deflection shaft 44. When the mounting hook 43 is unloaded, the spring 45 can be in a compressed state to prevent the mounting hook 43 from vibrating.

[0094] In the embodiment of the present application, the upper end of the fixing cylinder 41 is provided with a fixing arm extending horizontally from one side of the deflection notch for fixing and mounting with the chain 7. Two adjacent extension shafts 71 can be arranged on the chain 7 at equal intervals toward the lower side, and the extension shafts 71 can be extended based on the existing shaft body in the chain 7. The fixing arm is provided with docking holes corresponding to the two adjacent extension shafts 71, and the two extension shafts 71 are inserted into and passed through the docking holes and fixed by calipers 72, so that the deflection hook 4 is fixed at equal intervals on the lower side of the chain 7, and then cyclically operates.

[0095] It is understandable that the load support of the deflection hook 4 is provided by the chain 7, and the chain 7 is subject to the horizontal limiting effect of the limiting channel, and can always maintain a relatively horizontal posture and circulate, thereby ensuring that the height of the clothes in the dryer does not change. Furthermore, the overall weight of the clothes and the carrier is relatively low, the number of clothes loaded and dried at a single time is limited, and the channel rails and drive motors can meet actual needs.

[0096] In the present application, the front end of the station entry device 1 is docked with the distribution device 8, and the rear end of the station entry device 1 is matched with the deflection hook 4, so that the carrier released by the distribution device 8 is transferred to the conveying line of the dryer for drying. After the deflection hook 4 is loaded with the carrier, it deflects and cooperates with the dryer to perform the drying operation.

[0097] It can be understood that the distribution device 8 is connected to the hanging production line to release the carriers on the hanging production line one by one onto the entry track of the entry device 1, and cooperate with the deflection hooks 4 distributed at equal intervals to mount them one by one and enter the transport line of the dryer for drying operations.

[0098] The front end of the exit device 2 is unhooked and matched with the deflection hook 4, and the rear end of the exit device 2 is docked with the slide rail 5, so that the carrier on the deflection hook 4 is transferred to the slide rail 5 and enters the subsequent production line track.

[0099] In an embodiment of the present application, the entry device 1 includes a guide rail 11, a temporary storage rail 12, and a driving device 13. The guide rail 11 is docked with the distribution device 8. The temporary storage rail 12 is placed directly below the running track of the deflection hook 4 and is provided with a groove. The front end of the groove is smoothly docked to the guide rail 11. The driving device 13 is arranged on the inner side of the guide rail 11 and the temporary storage rail 12, and the driving track of the driving device 13 corresponds to the rear section of the guide rail 11 and the front section of the groove, so that the carrier distributed to the guide rail 11 can be pushed to the rear section of the groove by the driving device 13; when the deflection hook 4 passes through the rear section of the groove, the bent hook of the deflection hook 4 is below the upper end surface of the groove.

[0100] The temporary storage rail 12 is arranged in parallel with the carrying rail 3, and the deflection hook 4 can pass through the groove along the center line of the groove.

[0101] In the embodiment of the present application, the front section of the guide rail 11 is raised and provided with a docking joint and a warping portion, and the rear section of the guide rail 11 is horizontally provided with a right-angled bending portion, the front end of the bending portion is docked and fixed with the warping portion, and the front end of the warping portion is fixed with the docking joint, and the docking joint is used to dock to the output end of the distribution rail of the distribution device 8; the rear end of the bending portion is docked with the temporary storage rail 12.

[0102] The temporary storage rail 12 and the bent portion are in the same plane, and the groove is opened on the upper surface of the temporary storage rail 12, so that after the distribution device 8 distributes and releases the carrier, the carrier needs external power to move to the rear section of the groove.

[0103] Specifically, slopes are provided on the two groove walls at the front section of the groove, and the slopes are provided along the direction of the temporary storage rail 12, and the lengths and slopes of the two slopes are the same; the bottom of the slopes is flush with the upper surface of the guide rail 11, so that when the carrier on the guide rail 11 is driven, it can be hung on the two groove walls and climb along the slopes to the rear section of the groove.

[0104] It should be clear that when the deflection hook 4 is in a normal posture, the hook faces straight ahead; when the deflection hook 4 is in a deflection posture, the hook produces a relative deflection; when the deflection hook 4 in a normal posture passes through the rear section of the groove, it can push the carrier located on the rear section of the groove forward until it is separated from the fall and the mounting combination is completed, thereby the load-bearing deflection hook 4 is in a deflected posture and runs along the carrier rail 3.

[0105] It can be understood that the power for the vehicle to climb along the slope is provided by the driving device 13, and after the vehicle is in the rear section of the groove, the power for its forward movement is provided by the deflection hook 4 in a normal posture.

[0106] In an embodiment of the present application, the driving device 13 includes a gear group, a positioning plate 131, a driving chain 132, and a brush 134. The positioning plate 131 is horizontally fixed to the inner side of the guide rail 11 and the temporary storage rail 12. The gear group is installed on the lower side of the positioning plate 131 to drive the driving chain 132 to circulate. A plurality of brushes 134 are horizontally fixed to the outside of the driving chain 132, and the plurality of brushes 134 are evenly spaced along the driving chain 132. The gear group includes a plurality of gears, and the plurality of gears are distributed along the direction of the guide rail 11 and the temporary storage rail 12, so that the driving trajectory of the brush 134 on the driving chain 132 can match the direction of the guide rail 11 and the temporary storage rail 12, thereby pushing the carrier thereon to slide through the brush 134.

[0107] In the present application, the spacing between the drive chain 132 and the guide rail 11 and the temporary storage rail 12 matches the length of the brush 134, so that the brush 134 can separate and push the carriers (hangers) thereon. The sorting speed of the sorting device 8 matches the running speed of the brush 134, so that the carriers separated and released by the sorting device 8 correspond to the brushes 134 one by one, that is, there is only one carrier between the two brushes 134.

[0108] The running speed and interval of the deflection hook 4 should match the distribution speed of the carrier, so that each deflection hook 4 only corresponds to one carrier for mounting at a time to avoid the phenomenon of multiple loads falling. When adjusting the running speed and interval of the deflection hook 4, the driving delay of the driving device 13 on the carrier should be considered.

[0109] Specifically, the running speed and distribution spacing of the deflection hooks 4 on the carrier rail 3 can be adjusted so that the running interval of the deflection hooks 4 can be staggered with the interval of the carrier reaching the rear section of the groove, and only one deflection hook 4 is matched for each carrier.

[0110] In an embodiment of the present application, the exit device 2 includes a base 21 and a isotope plate 22. The base 21 is placed directly below the running track of the deflection hook 4. Both sides of the base 21 are provided with docking notches for aligning the isotope plate 22, so that the deflection hook 4 can pass between the isotope plates 22; both sides of the isotope plate 22 are symmetrically sloped downward, and the highest point of the isotope plate 22 is higher than the mounting combination limit of the deflection hook 4 and the vehicle; the front end of the base 21 is inclined downward and is provided with a guide head, so that the guide head can be located below the deflection hook 4 and inserted into the inside of the bent hook of the vehicle, thereby guiding the bent hook of the vehicle to be hung on the isotope plate. When the deflection hook 4 loads the vehicle and runs to the highest point of the isotope plate 22, the vehicle can be unhooked from the deflection hook 4.

[0111] In an embodiment of the present application, the front end of the guide head is offset outward to facilitate docking and insertion into the hanger hook in a deflected posture. The offset structure adopts an arc-shaped smoothing treatment, and the inner offset arc of the front end of the guide head is greater than the outer offset arc, so that the front end structure of the guide head gradually shrinks, and the height of the upper surface of the guide head gradually decreases, and the height of the front end is the lowest, so as to facilitate the insertion of the guide head into the hook; the lower surface of the guide head is flush with the lower surface of the base 21.

[0112] When the guide head is inserted into the hook of the hanger, the hanger is in a deflected posture. As the deflection hook 4 runs, the posture of the hanger is gradually restored by the limiting effect between the guide head and the hook of the hanger. The upper surface of the guide head gradually approaches the bottom of the deflection hook 4 but never touches it. One side of the hanger rod of the hanger is located on the outside of the guide head until the deflection hook 4 passes between the isotropic plates 22. At this time, the hook of the hanger is simultaneously hung on the two plates of the isotropic plates 22.

[0113] In the present application, the mounting combination limit of the deflection hook 4 and the hanger is based on the mounting limit height of the deflection hook 4 and the hanger. The height of the deflection hook 4 is fixed. When the height of the hanger gradually rises and the limiting effect of the deflection hook 4 on the hanger fails, it is the mounting combination limit. At this time, the hanger can be horizontally taken out from the hook of the deflection hook 4. In the embodiment of the present application, the highest point height of the same position plate 22 exceeds the mounting combination limit. When the hanger reaches the highest point, its height also exceeds the mounting combination limit. At this time, the hanger is no longer limited by the front section inclined surface of the same position plate 22 and the hook of the deflection hook 4. It has been unhooked and can slide directly along the rear section inclined surface.

[0114] The same position plate 22 includes two triangular plates, which are fixed on both sides of the base 21 in parallel and aligned, and the deflection hook 4 passes between the same position plates 22. The top angle is the highest point of the same position plate 22, and the carrier is unhooked and separated at a height exceeding the mounting combination limit. The thickness of the triangular plate is the same as the depth of the docking notch, so that the same position plate 22 can smoothly transition with the guide head. Furthermore, the two bottom angles of the triangular plate can be cut into vertical structures to facilitate flush docking in the docking notch.

[0115] A secondary slope is provided at the top corner of the triangular plate, the lower end of the secondary slope is smoothly connected with the slope on the rear waist of the triangular plate, and the higher end of the secondary slope is connected with the slope on the front waist of the triangular plate. The slope of the secondary slope is smaller than the slope of the rear waist, so that the highest point of the same-position plate 22 is forward, and when the clothes hanger passes the highest point, it can slide down immediately. At this time, the mounting hook 43 of the deflection hook 4 is still within the shielding range of the same-position plate 22, which can effectively avoid the occurrence of secondary mounting combination.

[0116] As another embodiment, a plane structure can be opened at the top corner of the triangular plate to smoothly connect with the inclined surfaces on both sides of the waist, which can extend the running path of the deflection hook 4 after it is unhooked from the hanger, which is beneficial for the same position plate 22 to block the mounting hook 43, and avoid secondary mounting combination between the carrier and the deflection hook 4.

[0117] The exit device 2 also includes a guide body 23, which is provided with a bending structure inclined downward in the direction away from the carrier rail 3. The front end of the guide body 23 is connected to the rear end of the base 21, and the rear end of the guide body 23 is connected to the slide rail 5, so that the carrier can slide down along the rear section of the inclined surface of the isotropic plate 22 onto the slide rail 5.

[0118] Specifically, the guide body 23 includes a docking section, a guide section, and a plug-in section, wherein the guide section is the main structure, which is inclined downward and is arranged as a bending structure, and its bending direction deviates from the carrying track of the carrying rail 3, so that the subsequent running path of the hanger can be separated from the carrying line of the dryer. The docking section is arranged at the front end of the guide section for docking with the rear end of the base 21 and fixed, and the plug-in section is arranged at the rear end of the guide section for docking with the slide rail 5 and plugging and fixing. The upper surfaces of the docking section, the guide section, and the plug-in section are all smoothly docked, so that after the rear section of the hanger slides onto the guide body 23, it can slide down smoothly.

[0119] The slide rail 5 includes a slide rib 51 and a support body 52. ​​A snap-fit ​​strip is arranged in parallel at the lower part of the slide rib 51 and a snap-fit ​​groove is arranged in parallel at the upper part of the support body 52, so that the slide rib 51 can be snap-fitted and installed on the support body 52; the upper surface of the slide rib 51 is not higher than the upper surface of the guide body 23. The slide rail 5 is designed to be sunken so that the carrier on it can slide down automatically.

[0120] When the deflection hook 4 carries the vehicle to the guide head, the guide head is inserted into the inside of the curved hook of the vehicle. At this time, the vehicle and the deflection hook 4 are still in a mounted combination state; when the deflection hook 4 continues to move forward, the curved hook of the vehicle is guided and limited by the guide head, so that the curved hook of the vehicle is simultaneously hooked to the isotope plates 22 on both sides of the base 21, and climbs upward along the inclined surface of the front section of the isotope plate 22. During the climbing process, the mounting combination of the deflection hook 4 and the vehicle is gradually unhooked; when reaching the highest point of the isotope plate 22, the vehicle and the deflection hook 4 have been unhooked, and the vehicle can slide down along the inclined surface of the rear section of the isotope plate 22. At this time, the hanging structure of the deflection hook 4 is within the shielding range of the isotope plate 22, and will not produce a secondary mounting combination with the vehicle.

[0121] Furthermore, the slopes of the front and rear inclined surfaces of the isotropic plate 22 can be adjusted so that when the vehicle is at the highest point and is sliding down, the hanging structure of the deflection hook 4 cannot complete the secondary hanging combination with the sliding vehicle while continuing to operate.

[0122] It can be understood that when the guide head is inserted into the curved hook of the carrier, it will affect the deflection angle of the deflection hook 4. Since the carrier has completed the drying of the garments at this time, the deflection of the carrier will no longer have any effect. As the carrier moves upward along the front inclined surface, the load on the deflection hook 4 is reduced, and the hanging structure will automatically deflect in the opposite direction, reset, and rise to a certain height. This rising height will no longer change after the unhooking is completed.

[0123] In the embodiment of the present application, a tensioning device may be provided for the driving device 13, and the tensioning device is installed between the positioning plate 131 and the gear set to tension the driving chain 132. The driving motor 135 is located on the upper side of the positioning plate 131 and establishes a transmission relationship with the gears in the gear set except the tensioning gear 133.

[0124] The gear set includes a main gear, two secondary gears and a tensioning gear. The main gear is installed in the bending area of ​​the bending portion, and the two secondary gears are correspondingly arranged at both ends of the bending portion. The tensioning gear 133 can be located between the two secondary gears. The running trajectory of this section of the drive chain 132 belongs to the invalid driving range.

[0125] The tensioning device specifically includes an arc-shaped tensioning hole opened on the positioning plate 131, and a tensioning connecting rod located on the upper side of the positioning plate 131, wherein the tensioning connecting rod includes a cross-shaped rotating rod and a limit rod, one end of the rotating rod is connected to the upper side of the positioning plate 131, and the other end is connected to the tensioning gear 133 in the gear group through the tensioning hole, so that when the rotating rod rotates, the tensioning gear 133 synchronously generates a deflection displacement, thereby tightening the drive chain 132 connected to the gear group.

[0126] The rotation rod is located on the upper side of the positioning plate 131, and a limit plate is vertically arranged upward. The limit plate is provided with a limit hole, and the limit rod is fixed on the upper side of the positioning plate 131 and inserted into the limit hole. When the drive chain 132 is tensioned, the limit rod can be inserted into the limit hole first, so that the tensioning gear 133 carried by the rotation rod can be in the horizontal position of other gears in the gear set, and the rotation angle of the rotation rod is adjusted to achieve the tensioning of the drive chain 132. At the same time, the rotation rod is fixed for tensioning and locking, and the limit relationship between the limit rod and the limit plate is used for secondary locking.

[0127] In the embodiment of the present application, the supporting frame required for the carrier rail 3, the slide rail 5, the inbound device 1, the outbound device 2, etc. is as follows: Figure 1 As shown in , additions can be made according to actual needs. For example, the driving device 13 of the station entry device 1 can be fixed by setting a hanging frame on the upper side of the positioning plate 131 attached to the frame on the right side to fix the driving device 13 and the station entry rail structure in the same plane to implement an effective driving function.

[0128] The fastening device 36 in the present application includes a horizontal plate, a nut, and a fastener. The fastener is embedded in the upper clamping channel of the steel section 31 and is fixed through the horizontal plate and the nut. The two sides of the horizontal plate are respectively covered on the channel rails on both sides of the steel section 31 and fixed by fastening nails. The side of the channel rail corresponds to the clamping channel of the steel section 31 to set a clamping structure.

[0129] In an embodiment of the present application, the exit device 2 also includes an exit plate 24 for fixing the base 21. The exit plate 24 includes a base plate and a fixed plate. The upper end of the fixed plate is fixed to the steel section, and the lower end of the fixed plate is provided with a sinking structure fixed to the horizontally arranged base plate. The base plate is docked under the base 21 to support the base 21 and the front guide head. The bottom plate of the sinking structure is lower than the base 21, reserving space for the unhooking operation of the hanger.

[0130] The station entry device 1 also includes an entry plate 14 for fixing the temporary storage rail 12. The entry plate 14 includes an upper fixed plate, a vertical plate, and a lower base plate. The upper fixed plate is fixed to the steel section 31, and the vertical plate is perpendicular to the upper fixed plate and the lower base plate respectively. The end of the lower base plate corresponds to the transport track on one side, so that the temporary storage rail 12 fixed on the lower base plate can be located directly below the transport track, thereby matching the running track of the deflection hook 4 with the groove.

[0131] The setting of the sinking structure can lift the base 21, the same position plate 22, and the guide rail 11 in space, and the two sides are open and do not interfere with the sliding of the hanger, which helps the hanger to be unhooked smoothly.

[0132] The steel section 31 in the present application can be made of conventional plastic steel section material, and the four sides can be provided with clamping channels, which will not be described in detail here.

[0133] The basic structures of the chain 7 and the drive chain 132 in the present application are common chain structures and will not be described in detail here.

Docking notches are provided on both sides of the base body (21) for installing the co-positioning plate (22) in position, so that the deflection hook (4) can pass through between the co-positioning plates (22); slopes are symmetrically provided downward on both sides of the co-positioning plate (22), and the highest point of the co-positioning plate (22) is higher than the mounting combination limit of the deflection hook (4) and the carrier; the front end of the base body (21) is inclined downward and converged with a guiding head, so that the guiding head can be inserted into the hook of the carrier below the deflection hook (4), thereby guiding the hook of the carrier to hang on the co-positioning plate. When the deflection hook (4) carries the carrier to run to the highest point of the co-positioning plate (22), the carrier can be decoupled from the deflection hook (4).

9. A carrier device for a tunnel dryer according to claim 8, wherein, the outbound device (2) further includes a guiding body (23). The guiding body (23) is inclined downward with a bending structure in a direction deviating from the carrier track (3). The front end of the guiding body (23) is docked to the rear end of the base body (21), and the rear end of the guiding body (23) is docked to the slide rail (5), so that the carrier can slide down along the rear inclined surface of the co-positioning plate (22) onto the slide rail (5).

10. A carrier device for a tunnel dryer according to claim 8, wherein, the co-positioning plate (22) includes two triangular plates. The two triangular plates are fixed in parallel in position on both sides of the base body (21). The thickness of the triangular plate is the same as the depth of the docking notch, so that the co-positioning plate (22) can have a smooth transition with the guiding head.

11. A carrier device for a tunnel dryer according to claim 10, wherein, a secondary inclined surface is provided at the apex angle of the triangular plate, and the slope of the secondary inclined surface is smaller than the slope of the rear inclined surface of the co-positioning plate (22), so that after the carrier is decoupled from the deflection hook (4) and passes over the highest point of the co-positioning plate (22), it can immediately slide down without generating a secondary mounting combination with the deflection hook (4).

12. A carrier device for a tunnel dryer according to claim 1, wherein, The lengths of the upper and lower end faces of the deflection notch are greater than the lengths of the upper and lower end faces of the connecting body (432). The upper end face of the connecting body (432) is correspondingly abutted against the upper end face of the deflection notch, and the lower end face of the connecting body (432) is correspondingly abutted against the lower end face of the deflection notch, so that the mounting hook (43) can automatically deflect when bearing a load and can automatically reset when the mounting hook (43) is unloaded.

13. A conveying device for a tunnel dryer according to claim 1, characterized in that the mounting cylinder includes a fixed cylinder (41) and a docking cylinder (42). An upper notch is formed in the lower annular wall of the fixed cylinder (41), and a lower notch is formed in the upper annular wall of the docking cylinder (42). The fixed cylinder (41) and the docking cylinder (42) are aligned and docked and fixed by the deflection shaft (44), so that the upper notch and the lower notch are aligned and docked and communicated to form the deflection notch.

14. A conveying device for a tunnel dryer according to claim 13, characterized in that a fixed arm horizontally extends from the upper end of the fixed cylinder (41) on the side where the deflection notch is formed. Two adjacent extension shafts (71) are arranged at equal intervals on the lower side of the chain (7). Docking holes are formed in the fixed arm corresponding to the two adjacent extension shafts (71). After the two extension shafts (71) pass through the docking holes, they are fixed by calipers (72), so that the deflection hooks (4) are fixed to the lower side of the chain (7) at equal intervals.
