Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying air box for laundry sheets. Background Technology

[0002] Laundry detergent sheets are products made by crushing, mixing, shaping, and drying various components. The current production methods, primarily manual brushing and natural air drying, are overly traditional, inefficient, and fail to meet market demand, posing a significant obstacle to their widespread use. Furthermore, the internal structure of current laundry detergent sheet drying ovens is relatively simple, consisting of multiple layers. This design results in uneven heating of the sheets, making them prone to deformation and cracking. Since laundry detergent sheets need good support during drying to prevent deformation while minimizing drying time, a suitable drying oven for laundry detergent sheets is required. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a laundry sheet drying air box to solve the problem of drying laundry sheets in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A laundry detergent drying box, comprising:

[0006] The housing contains a conveyor frame with a conveyor belt. A hot air frame is located below the conveyor frame, and multiple hot air chambers are evenly distributed along the conveying direction of the conveyor belt on the hot air frame. A hot air blower is located on one side of the housing, and the output end of the hot air blower is connected to the hot air chamber. The opening of the hot air chamber faces the conveyor belt to heat the surface of the conveyor belt. An air outlet is located on the upper side of the housing to exhaust the hot air from inside the housing.

[0007] To achieve the above technical solution, a hot air frame is installed under the conveyor frame. The hot air chamber on the hot air frame heats the conveyor belt on the conveyor frame, thereby increasing the surface temperature of the conveyor belt to meet the drying requirements of the laundry sheets conveyed on the conveyor belt. The opening of the hot air chamber is set towards the conveyor belt to heat the surface of the conveyor belt. The hot air output from the hot air blower can heat the conveyor belt under the conveyor frame. As the conveyor belt runs, the heated conveyor belt under the conveyor frame will move to the upper side to receive the formed laundry sheets and perform heat exchange drying on the laundry sheets. After the temperature of the conveyor belt carrying the laundry sheets drops, it will move back to the lower side of the conveyor frame to receive drying from the hot air chamber. This process is repeated to achieve a continuous drying effect on the laundry sheets.

[0008] In one embodiment of the present invention, the hot air chamber has a trumpet-shaped cross-section, and an upwardly extending connecting plate is provided on the upper side of the hot air chamber, the connecting plate being connected to the hot air frame.

[0009] To achieve the above technical solution, by making the cross-section of the hot air chamber funnel flared, the uniformity of the hot air output from the hot air chamber heating the conveyor belt can be improved. The setting of the connecting plate can improve the stability of the hot air chamber in use, and can also guide the hot air flow, so that the hot air can flow fully to the conveyor belt.

[0010] In one embodiment of the present invention, the hot air chamber is spaced apart from the box body on both sides, and a baffle plate is provided in the spaced space.

[0011] To achieve the above technical solution, by matching the spaced sides of the hot air chamber with the box body, the size of the conveyor belt can be better matched, the heating effect of the hot air output from the hot air chamber on the conveyor belt can be improved, and the setting of the baffle plate can reduce the dispersion of hot air.

[0012] In one embodiment of the present invention, a support plate is provided on the lower side of the wind baffle, and the support plate is supported between the side wall of the box and the bottom surface of the wind baffle.

[0013] To achieve the above technical solution, the installation of the support plate can improve the support stability of the wind baffle and enhance the reliability of the wind baffle's support for the hot air chamber.

[0014] In one embodiment of the present invention, a barrier net is provided inside the opening surface of the hot air chamber, a support rod is provided on the lower side of the barrier net, and the barrier net is circumferentially attached to the inner wall of the hot air chamber.

[0015] To achieve the above technical solution, the barrier net can prevent external debris from falling into the hot air chamber, while also dispersing the hot air output from the hot air chamber evenly, thereby improving the heating effect on the surface of the conveyor belt.

[0016] In one embodiment of the present invention, the air outlet is provided in multiple sets, and each set of air outlets is located on the upper side of the hot air box.

[0017] To achieve the above technical solution, each set of air outlets is located on the upper side of the hot air box, which can improve the air outlet effect and prevent the temperature inside the box from getting too high.

[0018] In one embodiment of the present invention, a hot air duct is provided between the hot air blower output end and the hot air chamber, and a set of air inlet ducts is also provided at the hot air blower output end, with the air inlet of the air inlet ducts located on the upper side of the conveyor belt.

[0019] To achieve the above technical solution, the air inlet duct can recycle the hot air from the upper side of the conveyor belt, thereby improving the heating effect of the hot air blower.

[0020] As described above, the laundry sheet drying air box of this utility model has the following beneficial effects: by setting a hot air frame on the lower side of the conveyor frame, the hot air chamber on the hot air frame heats the conveyor belt on the conveyor frame, thereby increasing the surface temperature of the conveyor belt to meet the subsequent drying effect of the laundry sheets conveyed on the conveyor belt. The hot air chamber opening is set towards the conveyor belt to heat the surface of the conveyor belt. The hot air output of the hot air blower can be used to heat the conveyor belt on the lower side of the conveyor frame. As the conveyor belt runs, the heated conveyor belt located on the lower side of the conveyor frame will run to the upper side to receive the formed laundry sheets and perform heat exchange drying on the laundry sheets. After the temperature of the conveyor belt carrying the laundry sheets drops, it will move back to the lower side of the conveyor frame to receive the drying of the hot air chamber. This process is repeated to achieve a continuous drying effect on the laundry sheets. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figures 1 to 5 This utility model provides a laundry sheet drying air box, including a box body 1 with a conveyor frame 2 inside, a conveyor belt 3 on the conveyor frame 2, a hot air frame 4 on the lower side of the conveyor frame 2, and multiple sets of hot air chambers 5 evenly distributed on the hot air frame 4 along the conveying direction of the conveyor belt 3. A hot air fan is provided on one side of the box body 1, and the output end of the hot air fan is connected to the hot air chamber 5. The opening of the hot air chamber 5 faces the conveyor belt 3 to heat the surface of the conveyor belt 3. An air outlet 6 is provided on the upper side of the box body 1 to discharge the hot air inside the box body 1.

[0030] By installing a hot air frame 4 on the lower side of the conveyor frame 2, the hot air chamber 5 on the hot air frame 4 heats the conveyor belt 3 on the conveyor frame 2, thereby increasing the surface temperature of the conveyor belt 3 to meet the subsequent drying effect of the laundry sheets conveyed on the conveyor belt 3. The opening of the hot air chamber 5 is set facing the conveyor belt 3 to heat the surface of the conveyor belt 3. The hot air output from the hot air blower can heat the conveyor belt 3 on the lower side of the conveyor frame 2. As the conveyor belt 3 runs, the heated conveyor belt 3 located on the lower side of the conveyor frame 2 will run to the upper side to receive the formed laundry sheets and perform heat exchange drying on the laundry sheets. After the temperature of the conveyor belt 3 carrying the laundry sheets drops, it will move back to the lower side of the conveyor frame 2 to receive drying from the hot air chamber 5. This process is repeated to achieve a continuous drying effect on the laundry sheets.

[0031] The hot air chamber 5 has a funnel-shaped cross-section, and an upwardly extending connecting plate 7 is provided on the upper circumference of the hot air chamber 5. The connecting plate 7 is connected to the hot air frame 4. By making the cross-section of the hot air chamber 5 funnel-shaped, the uniformity of the hot air output from the hot air chamber 5 in heating the conveyor belt 3 can be improved. The setting of the connecting plate 7 can improve the stability of the hot air chamber 5 in use, and can guide the hot air flow so that the hot air can flow fully to the conveyor belt 3.

[0032] The hot air chamber 5 is spaced apart from the housing 1 on both sides, and a baffle plate 8 is provided in the space. By spaced apart between the hot air chamber 5 and the housing 1, the size of the conveyor belt 3 can be better matched, and the heating effect of the hot air output from the hot air chamber 5 on the conveyor belt 3 can be improved. The baffle plate 8 can reduce the dispersion of hot air.

[0033] A support plate 9 is provided on the lower side of the wind deflector 8. The support plate 9 is supported between the side wall of the housing 1 and the bottom surface of the wind deflector 8. The support plate 9 can improve the support stability of the wind deflector 8 and improve the support reliability of the wind deflector 8 to the hot air chamber 5.

[0034] A barrier net 10 is provided inside the opening of the hot air chamber 5. A support rod is provided on the lower side of the barrier net 10. The barrier net 10 is circumferentially attached to the inner wall of the hot air chamber 5. The barrier net 10 can prevent external debris from falling into the hot air chamber 5, while also dispersing the hot air output from the hot air chamber 5 evenly, thereby improving the heating effect on the surface of the conveyor belt 3.

[0035] There are multiple sets of air outlets 6, and each set of air outlets 6 is located on the upper side of the hot air box. This arrangement improves the air outlet efficiency and prevents the temperature inside the box 1 from getting too high.

[0036] A hot air duct is configured between the hot air blower output end and the hot air chamber 5. An air inlet duct 11 is also set at the hot air blower output end. The air inlet of the air inlet duct 11 is located on the upper side of the conveyor belt 3. The air inlet duct can circulate the hot air on the upper side of the conveyor belt, realize the circulation of hot air, and improve the heating effect of the hot air blower.

[0037] This invention features a hot air frame installed under the conveyor frame. The hot air chamber on the hot air frame heats the conveyor belt, increasing its surface temperature to ensure optimal drying of the laundry sheets. The hot air chamber opening faces the conveyor belt to heat its surface. Hot air from the hot air blower heats the conveyor belt under the conveyor frame. As the conveyor belt moves, the heated belt moves to the top to receive the formed laundry sheets and dry them through heat exchange. Once the temperature of the conveyor belt carrying the laundry sheets drops, it moves back to the bottom of the conveyor frame to receive further drying from the hot air chamber. This process repeats to achieve continuous drying of the laundry sheets.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
