Description

TECHNICAL FIELD

[0001] This utility patent relates to the technical field of fabric drying equipment, and specifically, to an electrically liftable and expandable fabric heating or drying cylinder.TECHNICAL BACKGROUND

[0002] A fabric drying cylinder, commonly referred to as a drying cylinder in the textile printing and dyeing industry, is one of main components of a cylinder drying machine. A main function of the fabric drying cylinder is to efficiently dry the fabric after washing or printing and dyeing. Heat is generated inside the drying cylinder through electric or steam heating. With rotation of the drying cylinder, the fabric tumbles continuously to ensure uniform heating. In addition, hot air comes into full contact with the fabric, to effectively remove moisture from the fabric, thereby improving drying efficiency.

[0003] To ensure that interiors of existing fabric drying cylinders can accommodate a large amount of fabric or be suitable for fabric with large sizes, the existing fabric drying cylinders are usually designed to have relatively large volumes, which are characterized by a considerable cylinder heights. Such large and tall structural design causes high transportation costs, occupies large space when not in use, making it inconvenient for storage. Therefore, in view of the foregoing problems, an electrically liftable and expandable fabric heating or drying cylinder is proposed.SUMMARY

[0004] To resolve technical problems, this utility patent provides an electrically liftable and expandable fabric heating or drying cylinder, a liftable cylinder body of the fabric drying equipment includes an upper cylinder and a lower cylinder, and the upper cylinder is slidably disposed in the lower cylinder. This structure endows the liftable cylinder body with a characteristic of expansion after being lifted. That is, during packaging for storage, the upper cylinder is lowered, to reduce an overall height of the liftable cylinder body, thereby reducing occupied space, further reducing transportation costs and facilitating storage. When in use, the upper cylinder is lifted, so that large accommodation space can be obtained. The electric lifting mechanism can drive the upper cylinder to automatically descend or ascend. Specifically, the electric lifting slide moves vertically along the lifting rail cylinder, to drive the lifting rod to lift and further jack up or lower the upper cylinder, thereby resolving technical problems in the prior art where fabric drying cylinders typically feature excessive bulkiness, leading to elevated transportation costs and user storage difficulties.

[0005] Technical solutions adopted to resolve the technical problems in the embodiments of this application are as follows:

[0006] An electrically liftable and expandable fabric heating or drying cylinder includes a heating cylinder bottom mounted with a liftable cylinder body, where a cylinder cover is rotatably connected to the liftable cylinder body, a drying rod is disposed in the liftable cylinder body, the liftable cylinder body includes an upper cylinder and a lower cylinder, and the upper cylinder is slidably disposed in the lower cylinder. The liftable cylinder body of the fabric drying equipment includes the upper cylinder and the lower cylinder, the upper cylinder is slidably disposed in the lower cylinder, and therefore, this structure endows the liftable cylinder body with a characteristic of expansion after being lifted. That is, during packaging for storage, the upper cylinder is lowered, to reduce an overall height of the liftable cylinder body, thereby reducing occupied space, further reducing transportation costs and facilitating storage. When in use, the upper cylinder is lifted, so that large accommodation space can be obtained.

[0007] In addition, the electrically liftable and expandable fabric heating or drying cylinder further includes an electric lifting mechanism mounted on an outer wall of the lower cylinder and configured to drive the upper cylinder to slide vertically in the lower cylinder, where the electric lifting mechanism includes a lifting rail cylinder in which a lifting rod is slidably disposed, a top end of the lifting rod is connected to the upper cylinder, and an electric lifting slide is disposed at a bottom end of the lifting rod.

When the drive motor works, the transmission gear can be driven to rotate, and the entire electric lifting slide can be driven to move vertically along the lifting rack in the lifting rail cylinder under a meshing effect between the transmission gear and the lifting rack, to complete lifting work of the upper cylinder.

[0009] In a possible implementation, the lower cylinder includes a lower thermal insulation shell whose top end is fixedly connected to a lower cylinder frame and whose outer cover is provided with a lower cylinder shell, and the upper cylinder includes an upper thermal insulation shell whose top end is fixedly connected to an upper cylinder frame and whose outer cover is provided with an upper cylinder shell. The foregoing structure can form a liftable cylinder body with a stable structure. The lower thermal insulation shell and the upper thermal insulation shell have a heat preservation and insulation function, and the lower cylinder shell and the upper cylinder shell have a protection and isolation function.

[0010] In a possible implementation, a roller base is fixedly arranged at a center of an outer wall of the lower cylinder shell, and a roller is rotatably installed at the roller base, where the roller is in rolling contact with an inner wall of the upper cylinder shell. The foregoing structure can resolve a balance problem in a lifting process of the upper cylinder through the roller and also significantly reduce friction between the upper cylinder and the lower cylinder.

[0011] In a possible implementation, the heating cylinder bottom includes a base mounted with a mounting baffle, a PTC heater is mounted on a lower end surface of the mounting baffle, and a heating fan is mounted at a lower end of the PTC heater. During operation, the heating fan can blow upward heat released by the PTC heater during its operation, so that hot air passes through the fabric inside the cylinder, thereby implementing a heating and drying effect. A middle air outlet net is erected on an upper end surface of the mounting baffle. The middle air outlet net can avoid scald and damage to the fabric caused due to direct contact between the fabric and the PTC heater. In addition, a drip-proof tray covering the PTC heater is mounted below the middle air outlet net. The structure can prevent water droplets on the fabric from falling onto the PTC heater and causing a short circuit.

[0012] In a possible implementation, a height restraint structure is fixedly disposed at the top end of the lifting rail cylinder, namely a height restraint Hall plate, and is configured to restrain the maximum movement distance of the electric lifting slide. The foregoing structure can avoid a failure of the connection between the lifting rod and the lifting rail cylinder caused because the electric lifting slide moves upward excessively.

[0013] In a possible implementation, a locking bolt is fixedly disposed on the cylinder cover, and a locking hole matching the locking bolt is disposed on the upper cylinder frame. The foregoing structure can implement the connection between the cylinder cover and the liftable cylinder body.

[0014] In a possible implementation, the drying rod is a U-shaped bent rod, a corresponding clamping groove is disposed on the inner wall of the upper cylinder frame, and two ends of the drying rod are clamped into the clamping groove of the upper cylinder frame. This structure can have a function of hanging the fabric, which can prevent the fabric from blocking the airflow and also ensure more uniform heating of the fabric, so that the drying is more efficient.

A middle air outlet net 16 is erected on an upper end surface of the mounting baffle 12. The middle air outlet net 16 can avoid scald and damage to the fabric caused due to direct contact between the fabric and the PTC heater 13. In addition, a drip-proof tray 15 covering the PTC heater 13 is mounted below the middle air outlet net 16. The structure can prevent water droplets on the fabric from falling onto the PTC heater 13 and causing a short circuit.

The foregoing structure can implement the connection between the cylinder cover 4 and the liftable cylinder body 2.

[0033] The drying rod 5 is a U-shaped bent rod, a corresponding clamping groove is disposed on the inner wall of the upper cylinder frame 24, and two ends of the drying rod 5 are clamped into the clamping groove of the upper cylinder frame 24. This structure can have a function of hanging the fabric, which can prevent the fabric from blocking the airflow and also ensure more uniform heating of the fabric, so that the drying is more efficient.

[0034] Use principle and use process of this utility patent:

[0035] The liftable cylinder body 2 of the fabric drying equipment includes the upper cylinder and the lower cylinder, the upper cylinder is slidably disposed in the lower cylinder, and therefore, this structure endows the liftable cylinder body 2 with a characteristic of expansion after being lifted. That is, during packaging for storage, the upper cylinder is lowered, to reduce an overall height of the liftable cylinder body 2, thereby reducing occupied space, further reducing transportation costs and facilitating storage. When in use, the upper cylinder is lifted, so that large accommodation space can be obtained. The electric lifting mechanism 3 can drive the upper cylinder to automatically descend or ascend. Specifically, the electric lifting slide 33 moves vertically along the lifting rail cylinder 31, to drive the lifting rod 32 to lift and further jack up or lower the upper cylinder.

[0036] A lifting principle of the electric lifting mechanism 3 is as follows: When the drive motor 34 works, the transmission gear 35 can be driven to rotate, and the entire electric lifting slide 33 can be driven to move vertically along the lifting rack 36 in the lifting rail cylinder 31 under a meshing effect between the transmission gear and the lifting rack 36, to complete lifting work of the upper cylinder.

[0037] In addition, during operation, the heating fan 14 can blow upward heat released by the PTC heater 13 during its operation, so that hot air passes through the fabric inside the cylinder, thereby implementing a heating and drying effect. A middle air outlet net 16 is erected on an upper end surface of the mounting baffle 12. The middle air outlet net 16 can avoid scald and damage to the fabric caused due to direct contact between the fabric and the PTC heater 13. In addition, a drip-proof tray 15 covering the PTC heater 13 is mounted below the middle air outlet net 16. The structure can prevent water droplets on the fabric from falling onto the PTC heater 13 and causing a short circuit.

For persons of ordinary skills in the art, other changes or modifications in different forms may also be made on the basis of the above descriptions. It is unnecessary and impossible to exhaust all embodiments. Obvious changes or modifications derived therefrom shall still fall within the protection scope of the utility patent.
