Abstract
Description
Technical Field
[0001] This utility model relates to the field of label production equipment technology, and specifically discloses a drying device for label processing. Background Technology
[0002] The origins of trademarks can be traced back to ancient times, when artisans imprinted their signatures or "marks" on their artworks or utilitarian products. Today, these marks have evolved into the trademark registration and protection system used worldwide. Paper trademarks, as a common type of trademark, are often used on clothing tags. Existing paper trademarks require drying equipment to clean them during the printing process.
[0003] Chinese patent CN211251775U discloses a label dryer, including a workbench and a housing. The housing is located on the upper side of the workbench. Support legs are arranged around the bottom of the workbench, and the upper sides of the support legs are fixed to the bottom of the workbench with bolts. Two guide shafts and one outlet shaft are arranged inside the housing on the upper side of the workbench, evenly distributed on the upper side of the workbench. Bearings are fitted at both ends of the guide shafts and outlet shaft, and the bearings are embedded inside the support frame. The bottom end of the support frame is fixed to the upper side of the workbench with bolts. A heating tube is arranged on the upper side of the housing, and the heating tube is fixed to the upper side of the housing with bolts. A fan is arranged inside the housing at the bottom end of the heating tube, and the fan is fixed to the housing with bolts. This invention uses heating tubes for heating. Although the heating efficiency of the heating tubes is relatively low, it can quickly generate heat to dry the labels, improving the drying quality of the labels.
[0004] The label dryer disclosed in the aforementioned document has a drying mechanism fixedly located on the top side of the label, which results in uneven drying of the top and bottom sides of the label and poor performance. Therefore, a drying device for label processing is needed to solve this problem. Utility Model Content

[0022] Please see Figure 1-3 A drying device for label processing includes a housing 1, with two electromagnetic heating rollers 4 installed inside the housing 1, labels installed on the outer walls of the two electromagnetic heating rollers 4, and two drying mechanisms installed inside the housing 1.
[0023] The drying mechanism includes a turntable 5, with an air cavity inside the turntable 5. Multiple air outlets 6 connected to the air cavity are opened on the lower end face of the turntable 5. An air inlet pipe 7 is connected to the upper end face of the turntable 5. A connecting pipe 9 is rotatably connected to the upper end of the air inlet pipe 7 through a rotating joint 8. A hot air blower 10 is installed on the outer wall of the housing 1. The air outlet of the hot air blower 10 is connected to the connecting pipe 9.
[0024] The drive mechanism is installed inside the housing 1.
[0025] In this embodiment: the label is flipped over by two electromagnetic heating rollers 4 so that the front and back sides of the label face the drying mechanism respectively, and the label can be dried by the electromagnetic heating rollers 4 (the electromagnetic heating rollers 4 are existing technology and will not be described in detail here). The hot air blower 10 is started, and the hot air blower 10 blows hot air into the air cavity in the turntable 5 and blows it out evenly from multiple air outlets 6. The turntable 5 can be rotated by the drive mechanism so that the hot air comes into even contact with the label and the drying is more uniform.
[0026] As a technical optimization of this utility model, the drive mechanism includes two worm gears 11 rotatably connected to the inner wall of the housing 1, and worm wheels 12 that mesh with the worm gears 11 are fixedly connected to the outer walls of the two air inlet pipes 7.
[0027] In this embodiment: Rotating the worm gear 11 causes the worm wheel 12 to rotate, which in turn causes the air inlet pipe 7 to rotate along the rotating joint 8 (the rotating joint 8 is existing technology, which can keep the two pipes rotating and sealed, and will not be described in detail here).
[0028] As a technical optimization of this utility model, a drive motor 14 with its output end fixedly connected to one of the worm gears 11 is installed on the rear end face of the housing 1. The front ends of both worm gears 11 extend to the outside of the housing 1 and are fixedly connected to pulleys 13. The two pulleys 13 are connected by belt drive.
[0029] In this embodiment: the drive motor 14 is started, and the drive motor 14 drives one of the worm gears 11 to rotate, which in turn drives the other worm gear 11 to rotate synchronously through the pulley 13 and the belt, thereby driving the two turntables 5 to rotate synchronously.
[0030] As a technical optimization of this utility model, two support plates 15 are fixedly connected between the front and rear end faces inside the box 1 and the air inlet pipe 7 through bearings.
[0031] In this embodiment, the support plate 15 facilitates the installation and support of the air inlet pipe 7.
[0032] As a technical optimization of this utility model, the left and right end faces of the box body 1 are respectively provided with a feed inlet 2 and a discharge outlet 3.
[0033] In this embodiment, by setting the inlet 2 and the outlet 3 on the left and right ends of the box 1 respectively, it is convenient to feed and discharge materials.
[0034] As a technical optimization of this utility model, a controller is provided on the outer wall of the box 1, and the electromagnetic heating roller 4, hot air blower 10 and drive motor 14 are all electrically connected to the controller.
[0035] In this embodiment, the controller facilitates the normal operation of the electromagnetic heating roller 4, the hot air blower 10, and the drive motor 14.
[0036] The working principle and usage process of this utility model are as follows: When in use, the hot air blower 10 and the drive motor 14 are started. The hot air blower 10 blows hot air into the air cavity inside the turntable 5 and blows it out evenly from multiple air outlets 6. The drive motor 14 drives one of the worm gears 11 to rotate, which in turn drives the other worm gear 11 to rotate synchronously through the pulley 13 and the belt. The worm gear 11 further drives the worm wheel 12 to rotate, which in turn drives the air inlet pipe 7 to rotate along the rotating joint 8. The air inlet pipe 7 further drives the turntable 5 to rotate, so that the hot air comes into even contact with the label. The label is flipped over by two electromagnetic heating rollers 4, so that the front and back sides of the label face the drying mechanism respectively. The electromagnetic heating rollers 4 can also assist in drying the label, making the drying more even.
