Abstract
Description
Technical Field
[0001] This utility model relates to the field of PP packaging tape production equipment, and in particular to a PP packaging tape dehumidification dryer. Background Technology
[0002] In the production process of PP packaging tape, the degree of dryness plays a crucial role in its quality and subsequent performance. PP packaging tape often absorbs moisture due to environmental factors after manufacturing or during storage. If effective dehumidification and drying are not carried out, numerous problems can arise. For example, the presence of moisture can cause air bubbles to form inside the tape during molding, reducing its mechanical strength and making it prone to breakage during subsequent use, thus failing to meet the requirements for packaging heavy items. Furthermore, PP packaging tape with excessive moisture content may exhibit uneven coloring, affecting the product's appearance and reducing its competitiveness in the market.
[0003] Traditional drying methods have significant drawbacks. Some companies use natural air drying, which is heavily limited by weather and space. During humid and rainy seasons, drying efficiency is extremely low, failing to meet the demands of large-scale production. Furthermore, natural air drying requires substantial space to store the packaging tape, increasing the company's space costs and management complexity. Other methods use simple hot air drying equipment, but the drying effect is unsatisfactory. Firstly, the hot air distribution in these devices is uneven, failing to reach all parts of the packaging tape comprehensively and evenly, resulting in inconsistent drying levels and affecting product quality stability. Secondly, they cannot precisely control temperature and humidity; excessively high temperatures may deform the PP packaging tape, while excessively low temperatures fail to completely remove moisture, severely impacting the quality of the packaging tape and production efficiency.
[0004] There is an urgent need in the market for equipment that can efficiently and evenly dehumidify and dry PP packaging tapes, and can precisely control the drying process, in order to overcome the shortcomings of traditional drying methods and meet the needs of PP packaging tape manufacturers for high-quality and high-efficiency production.

[0027] Reference Figures 1 to 3 A PP packaging belt dehumidification dryer includes a frame 10, a hot air blower 20, a drying base 30, a first tensioning assembly 40, and a second tensioning assembly 50.
[0028] The hot air blower 20 is mounted on the frame 10 and is used to provide hot air;
[0029] The drying base 30 is mounted on the frame 10 and has a horizontally arranged drying channel 60. The air inlet 31 of the drying base 30 is connected to the hot air blower 20 and the air outlet 32 is connected to the drying channel 60.
[0030] The first tensioning assembly 40 and the second tensioning assembly 50 are located on the left and right sides of the drying seat 30, respectively;
[0031] One end of the packaging tape 70 is wrapped around the first tensioning component 40, and the other end passes through the drying channel 60 and is wrapped around the second tensioning component 50. The packaging tape 70 can move along the length of the drying channel 60 under the traction of the traction device.
[0032] In this utility model, the dehumidifying dryer is positioned between the shaping and winding processes on the packaging tape production line. Specifically, the shaped packaging tape is first wound around the first tensioning component 40, then passed through the drying channel 60 of the drying seat 30, and then wound around the second tensioning component 50. Finally, in the winding process, the traction device on the winding process drives the packaging tape forward and winds it up. When the packaging tape moves forward in the drying channel 60, the hot air generated by the hot air blower 20 is transported from the air inlet 31 of the drying seat 30 through the pipe into the drying seat 30, and then blown onto the packaging tape by the air outlet 32 of the drying seat 30. The high-speed hot air generated by the hot air blower 30 is used to quickly dehumidify and dry the packaging tape.
[0033] Reference Figures 1-3 In some embodiments, the drying seat 30 is U-shaped, and the air outlet 32 is located on the left and right sides of the drying seat 30; further, the drying seat 30 is U-shaped, and the air outlet 32 is located on the upper and lower sides of the drying seat 30; even further, there are four air outlets 32, located on the upper left, upper right, lower left and lower right of the drying seat 30 respectively, so as to dry the packaging strip from four angles in all directions, which greatly improves the drying efficiency and drying effect.
[0034] Reference Figures 1-3 In some embodiments, the air outlet 32 is strip-shaped and arranged along the width direction of the packaging belt 70; this arrangement can increase the speed of the hot air blown out from the air outlet 32, which is beneficial to further improve the drying efficiency and drying effect.
[0035] Reference Figures 1-3 In some embodiments, the first tensioning assembly 40 includes a first substrate 41, a second substrate 42, a first tensioning roller 43, and a second tensioning roller 44. The first substrate 41 and the second substrate 42 are mounted on the frame 10 and are arranged on the front and rear sides of the drying seat 30, respectively. The first tensioning roller 43 and the second tensioning roller 44 are rotatably disposed between the first substrate 41 and the second substrate 42 and are staggered in the height direction. Specifically, the first tensioning roller 43 and the second tensioning roller 44 are configured as two sets, located obliquely above and obliquely below the drying seat 30, respectively. The set of first tensioning rollers 43 and the second tensioning roller 44 located obliquely above can dry one set of packaging tapes, and the other set of first tensioning rollers 43 and the second tensioning roller 44 located obliquely below can dry another set of packaging tapes. Further, the second tensioning assembly 50 includes a third substrate 51, The fourth substrate 52, the third tension roller 53, and the fourth tension roller 54 are mounted on the frame 10 and arranged on the front and rear sides of the drying seat 30. The third tension roller 53 and the fourth tension roller 54 are rotatably arranged between the third substrate 51 and the fourth substrate 52 and are staggered in the height direction. Corresponding to the above embodiment, the third tension roller 53 and the fourth tension roller 54 are set in two groups, located obliquely above and obliquely below the drying seat 30, respectively. The group of third tension rollers 53 and the fourth tension roller 54 located obliquely above can dry one group of packaging tapes, and the other group of third tension rollers 53 and the fourth tension roller 54 located obliquely below can dry another group of packaging tapes. Each group of packaging tapes is preferably set to 2 tapes, so as to realize the simultaneous drying of 4 packaging tapes, which greatly improves the drying efficiency.
[0036] Reference Figures 1-3 In some embodiments, the drying seats 30 are configured as two and arranged at intervals along the length of the packaging belt 70. This configuration enables two-stage drying of the packaging belt, further improving drying efficiency and drying effect.
[0037] Reference Figures 1-3 In some embodiments, the frame 10 is provided with a first return air seat 81 and a second return air seat 82 that can be opened or closed relative to the first return air seat 81. The first return air seat 81 and the second return air seat 82 enclose a drying space 83 along the length of the packaging belt 70, and the drying seat 30 is located in the drying space 83. This arrangement allows the hot air blown out by the drying seat 30 to stay in the drying space 83 for a longer time, thereby improving the drying effect. It also serves to shield the drying seat 30 and prevent accidental burns.
[0038] Reference Figure 1 In some embodiments, a handle 90 is provided on the second return air seat 82.
[0039] The advantages of this invention are: the above structure can quickly dehumidify the packaging tape, and it can be adapted to existing packaging tape production lines. It has the advantages of simple structure and high dehumidification efficiency, and meets the needs of use.
