Description

Technical Field

[0001] This utility model relates to the field of adhesive tape production technology, specifically to a low-allergy medical adhesive tape production equipment. Background Technology

[0002] Medical tapes typically consist of a substrate, an adhesive layer, and release paper.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-6 This utility model provides a new technical solution: a low-allergy medical tape production equipment, including a drying box 1, with a first rectangular groove 4 communicating with the interior of the drying box 1 on both the front and rear surfaces, a first partition 20 fixedly connected inside the drying box 1, two second partitions 21 fixedly connected to the upper surface of the first partition 20, both second partitions 21 being fixedly connected to the drying box 1, and a second rectangular groove 24 being opened on both first partitions 20, and a drying assembly, which is set on the drying box 1, and the drying assembly includes eight first fixing plates 10, which are respectively fixedly connected to the left and right sides of the drying box 1;

[0040] Two second air supply pipes 8 are provided on both the left and right sides of the drying box 1. The front and rear ends of the four second air supply pipes 8 are respectively fixedly connected to the corresponding first fixing plate 10.

[0042] Furthermore, the drying oven 1 is equipped with multiple air outlet boxes 18 arranged vertically and vertically. The multiple air outlet boxes 18 are used to preheat the medical tape, initially evaporate the moisture, and prevent the substrate from deforming due to sudden heat.

[0045] Furthermore, four second hot air blowers 22 are fixedly installed inside the drying oven 1, and the air outlets of the four second hot air blowers 22 are all fixedly connected to a third air supply pipe 9;

[0046] Among them, the ends of the four third air supply pipes 9 that are away from the second hot air blower 22 all penetrate through the outer surface of the drying box 1;

[0048] Furthermore, the drying oven 1 is equipped with multiple rotating tubes 19 inside, and the opposite sides of the multiple rotating tubes 19 are all fixedly connected to an air outlet box that communicates with the interior of the tubes 19.

[0049] Among them, the left and right sides of the multiple rotating tubes 19 are fixedly connected to the conveying rotating tubes 15 that communicate with their interiors, and the ends of the multiple conveying rotating tubes 15 that are away from the rotating tubes 19 rotate through the outer surface of the drying box 1.

A rack 11 is slidably connected to the concave part of the two concave plates 12.

[0051] Among them, the two racks 11 are respectively meshed with the corresponding gears 13, and two cylinders 14 are fixedly installed on the left side of the drying box 1. The extension and retraction ends of the two cylinders 14 are respectively fixedly connected to the corresponding racks 11.

[0052] Furthermore, two second fixing plates 17 are fixedly connected to both the right side and the upper surface of the drying box 1, and two first air supply pipes 5 are provided on the right side of the drying box 1.

[0053] The front and rear ends of the two first gas pipes 5 are respectively fixedly connected to the corresponding second fixing plates 17.

[0054] Furthermore, multiple L-shaped connecting pipes 16 that communicate with the interior of each of the two first gas pipes 5 are fixedly connected to their opposite sides.

[0055] Among them, multiple L-shaped connecting pipes 16 are rotatably connected to the corresponding conveying rotating pipes 15, and multiple L-shaped connecting pipes 16 are connected to the corresponding conveying rotating pipes 15.

[0056] Furthermore, two first hot air blowers 6 are fixedly installed on the upper surface and inside of the drying oven 1, and the air outlet pipes of the four first hot air blowers 6 are fixedly connected to the corresponding first air supply pipes 5 respectively.

[0057] The front and rear surfaces of the drying box 1 are fixedly connected with concave frames 2, and auxiliary rollers 3 are rotatably connected to the concave parts of the two concave frames 2.

[0058] Furthermore, when using this hypoallergenic medical tape production equipment, with the adhesive side of the hypoallergenic medical tape facing upwards, during the drying process, the front end of the hypoallergenic medical tape is first passed through the inner walls of the first rectangular groove 4 and the second rectangular groove 24, and then connected to the winding machine. Subsequently, the winding machine is started, causing the hypoallergenic medical tape to move slowly forward.

[0059] Subsequently, four second hot air blowers 22 and four first hot air blowers 6 are started, and two cylinders 14 are started to move back and forth continuously;

[0060] The hot air generated by the four second hot air blowers 22 enters the second air supply pipe 8 through the third air supply pipe 9, and is then transported to the multiple air outlet boxes 18 inside the drying oven 1 through the fourth air supply pipe 23. The air outlet boxes 18 blow hot air onto the surface of the tape to preheat the tape, initially evaporate the moisture, and prevent the substrate from deforming due to sudden heat.

[0061] Meanwhile, the hot air generated by the two first hot air blowers 6 enters the conveying rotating pipe 15 and rotating pipe 19 through the first air supply pipe 5 and the L-shaped connecting pipe 16, and finally sprays high-temperature hot air from the air outlet box opposite to the rotating pipe 19 to deeply dry the tape and ensure that the moisture in the adhesive layer is fully evaporated.

[0062] The drying components enable the drying chamber 1 to form a preheating zone and a main drying zone. The preheating zone preheats the tape and initially evaporates the moisture to prevent the substrate from deforming due to sudden heating. The main drying zone deeply dries the tape to ensure that the moisture in the adhesive layer is fully evaporated, thereby improving the drying quality of hypoallergenic medical tape.

[0063] Among them, two cylinders 14 are activated. The telescopic end of the cylinder 14 drives the rack 11 to move back and forth in the concave plate 12. The rack 11 drives the left conveying rotating tube 15 to rotate through the meshing gear 13, thereby making the rotating tube 19 and the air outlet box rotate synchronously. The air outlet box can adjust the hot air spray angle during rotation to ensure that the upper and lower surfaces of the tape are heated evenly and to avoid local overheating that could lead to carbonization of the adhesive layer or deformation of the substrate.

[0064] Among them, the auxiliary roller 3 is rotatably connected to the front and rear surfaces of the drying box 1 through the concave frame 2, which plays a supporting and guiding role for the moving tape, and works with the winding machine to keep the tape tension stable and prevent the tape from running off track or wrinkling during the drying process.

[0065] When the tape passes through the channel between the first partition 20 and the second partition 21, the corresponding upper and lower air outlet boxes form a three-dimensional drying area. The front air outlet box is preheated at a low temperature, and the rear air outlet box is dried at a high temperature, forming a gradient drying process to improve drying efficiency and tape quality. After drying, the tape passes through the first rectangular groove 4 on the other side and is wound into a roll by a winding machine. Throughout the process, hot air is circulated through the air supply pipe, and excess moisture is discharged through the exhaust port at the top of the drying box 1 to ensure the stability of the drying environment.
