Description

Technical Field

[0001] This utility model relates to the field of packaging production technology, and more specifically to a heat shrink film drying tunnel device with adjustable wind speed. Background Technology

[0002] The heat shrink film drying tunnel device is a key piece of equipment in the packaging production line. It is mainly used to heat and shrink the heat shrink film (such as POF, PVC, PE and other materials) after the product is packaged, so that it fits tightly to the product surface to achieve the purpose of being beautiful, dustproof, moisture-proof or fixing the product.

[0003] However, in actual use, the heating wind speed of existing heat shrink film drying tunnel devices cannot be adjusted according to actual needs. Therefore, if the wind force is too strong, it will cause the film to break or if the wind force is insufficient, it will cause incomplete shrinkage. Furthermore, when heating the heat shrink film, a large amount of heat will be dissipated to the outside, resulting in a large waste of heat energy. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat shrink film drying tunnel device with adjustable wind speed to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a heat shrink film drying tunnel device with adjustable wind speed, comprising a heat drying oven, characterized in that: heat-conducting boxes are fixedly connected to the top of the heat drying oven and near its four corners; heat-conducting pipes are fixedly connected to one side of the surface of each heat-conducting box; protective shells are provided on the top of the heat drying oven and near its two edges; a drive shaft is movably connected to the adjacent side of the protective shell and located at the top of the heat drying oven; neatly arranged heat insulation curtains are provided on both sides of the surface of the heat drying oven; a hot air fan is fixedly connected to the heat drying oven and located on the side adjacent to the heat insulation curtains; and the interior of the heat drying oven... Each part is fixedly connected to a wind speed regulating component at the location of the fixed connection to the hot air fan. A servo motor is fixedly connected to the protective shell on the side away from the hot air oven. This utility model, by providing a wind speed regulating component, a servo motor, a transmission shaft, and a meshing gear, is beneficial to adjust the wind speed when needed. The servo motor starts and drives the transmission shaft and meshing gear to rotate, and the meshing gear drives the regulating plate to rotate. This causes the regulating holes on the surface of the regulating plate to intersect with the holes on the surface of the wind deflector, thereby changing the wind speed entering the hot air oven and avoiding excessive wind force causing membrane damage or insufficient wind force causing incomplete shrinkage.

[0006] Furthermore, the hot drying oven has a hot drying cavity inside, and a reflux box is fixedly connected to the bottom of the hot drying oven. The reflux box has regularly arranged reflux holes around its surface, and the end of the heat conduction pipe away from the heat conduction box is fixedly connected to the inside of the reflux holes.

[0007] Furthermore, the wind power regulating component includes a wind deflector, an adjusting disc is movably sleeved inside the wind deflector, a transmission gear is provided on the surface of the adjusting disc, a meshing gear is connected to the top of the transmission gear, the meshing gear is movably sleeved inside the protective shell, and the adjusting disc has regularly arranged adjusting holes.

[0008] Furthermore, the hot air oven has a rectangular hot air hole at the position where the hot air fan is fixedly connected, a transmission groove is provided on the top of the hot air oven at the position where the transmission shaft is movably connected, and a gear groove is provided on the top of the hot air oven at the position where the protective shell is fixedly connected.

[0009] Furthermore, a heat recovery chamber is provided inside the reflux box, and a series of regularly arranged circular holes are provided at the top of the reflux box. Heat conduction holes are provided at the locations where the heat conduction pipes are fixedly connected to the heat conduction box.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model, by incorporating a wind speed adjustment component, a servo motor, a transmission shaft, and meshing gears, facilitates the adjustment of wind speed when necessary. The servo motor drives the transmission shaft and meshing gears to rotate, which in turn drives the adjustment disc to rotate. This causes the adjustment holes on the surface of the adjustment disc to intersect with the holes on the surface of the wind deflector, thereby changing the wind speed entering the hot drying oven. This prevents excessive wind from damaging the membrane or insufficient wind from causing incomplete shrinkage.

[0012] 2. This utility model, by providing a heat-conducting box, heat-conducting pipe, reflux box, and heat insulation curtain, helps to block the heat inside the oven, reduce heat loss, and allow some heat energy to enter the reflux box through the heat-conducting box and heat-conducting pipe, thereby enabling the heat energy to be reused and avoiding waste.

[0019] Reference Figure 1 - Figure 4 As shown, this utility model provides a heat shrink film drying tunnel device with adjustable wind speed, including a heat drying oven 1. The device is characterized by: heat-conducting boxes 2 fixedly connected to the top of the heat drying oven 1 and near its four corners; heat-conducting pipes 3 fixedly connected to one side of each heat-conducting box 2; protective shells 4 opened on the top of the heat drying oven 1 and near its edges on both sides; a drive shaft 5 movably connected to the adjacent side of the protective shell 4 and located at the top of the heat drying oven 1; neatly arranged heat insulation curtains 8 opened on both sides of the surface of the heat drying oven 1; hot air fans 7 fixedly connected to the heat drying oven 1 and adjacent to the side where the heat insulation curtains 8 are located; and various heat insulation curtains 7 fixedly connected to the inside of the heat drying oven 1 at the locations where the hot air fans 7 are fixedly connected. A wind force regulating component 10 is fixedly connected, and a servo motor 6 is fixedly connected to the protective shell 4 on the side away from the hot oven 1. This utility model, by providing a wind force regulating component 10, a servo motor 6, a transmission shaft 5, and a meshing gear 11, is beneficial to adjust the wind speed when needed. The servo motor 6 starts and drives the transmission shaft 5 and the meshing gear 11 to rotate, and the meshing gear 11 drives the regulating plate 1002 to rotate, so that the regulating holes 12 on the surface of the regulating plate 1002 and the holes on the surface of the wind baffle 1001 are interlaced, thereby changing the wind speed entering the hot oven 1, avoiding excessive wind force causing membrane damage or insufficient wind force causing incomplete shrinkage.

[0020] The oven 1 has a hot drying cavity 101 inside, and a reflux box 9 is fixedly connected to the bottom of the oven 1. The reflux box 9 has reflux holes 901 arranged in a regular pattern around its surface. The end of the heat conduction pipe 3 away from the heat conduction box 2 is fixedly connected to the inside of the reflux hole 901.

[0021] The wind-powered regulating component 10 includes a wind deflector 1001, an regulating disc 1002 is movably sleeved inside the wind deflector 1001, a transmission gear 1003 is provided on the surface of the regulating disc 1002, a meshing gear 11 is connected to the top of the transmission gear 1003, the meshing gear 11 is movably sleeved inside the protective shell 4, and a regularly arranged regulating hole 12 is provided on the surface of the regulating disc 1002.

[0022] The hot oven 1 has a rectangular hot air hole 102 at the position where the hot fan 7 is fixedly connected, a transmission groove 103 at the top of the hot oven 1 and at the position where the transmission shaft 5 is movably connected, and a gear groove 104 at the top of the hot oven 1 and at the position where the protective shell 4 is fixedly connected.

[0023] The reflux box 9 has a heat recovery chamber 902 inside, and a regularly arranged circular hole is provided at the top of the reflux box 9. The heat conduction box 2 has heat conduction holes 201 at the position where it is fixedly connected to the heat conduction pipe 3.

[0024] The working principle of this utility model is as follows: First, when using the device, the object wrapped in heat-shrink film is placed through the heat insulation curtain 8. Then, the hot air fan 7 is turned on, sending heated air into the inner drying cavity 101. When the airflow speed needs to be adjusted, the servo motor 6 is activated, causing the transmission shaft 5 to rotate. The transmission shaft 5 then drives the meshing gear 11 inside the protective shell 4. The meshing gear 11, located in the gear groove 104, drives the transmission gear 1003. The transmission gear 1003 then drives the adjusting disc 1002 to rotate inside the windbreak cover 1001. At this time, the adjustment holes 12 on the surface of the adjustment plate 1002 and the holes on the surface of the wind baffle 1001 are intertwined. The hot air speed is changed by the size of the interlacing of the adjustment holes 12 and the holes on the surface of the wind baffle 1001. Then, the heat inside the hot drying cavity 101 is blocked by the heat insulation curtain 8, thereby reducing heat loss. Then, some of the heat energy reaches the position of the heat conduction pipe 3 through the heat conduction box 2. Then, the heat is conducted to the position of the return hole 901 through the heat conduction pipe 3. Then, the heat enters the heat recovery cavity 902 through the return hole 901. Then, the heat flows back to the inside of the hot drying cavity 101 through the top hole of the return box 9 for reuse, thus avoiding the waste of heat energy.

[0025] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
