Abstract
Description
Technical Field
[0001] This utility model relates to the field of PET sheet production technology, specifically to a glue drying device for a PET sheet extrusion production line. Background Technology
[0002] In the production process of PET sheets, it is sometimes necessary to coat the surface of the PET sheets with adhesive to achieve specific functions. In order to make the adhesive solidify quickly, it is generally necessary to dry the adhesive after coating.
[0003] A search revealed Chinese patent CN214984000U, which discloses a glue drying device for a PET sheet extrusion production line. The device includes a worktable with a movable frame slidably connected to its top. A drying ring tube is sleeved on the outside of the worktable, and an air guide pipe is connected to one side of the drying ring tube. An electric heating tube is fixedly installed on the outside of the air guide pipe. This invention places the PET sheet body on the movable frame. The movable frame moves downwards under the weight of the PET sheet body, pushing a first straight rod downwards. Two pistons then drive a second straight rod upwards, causing a clamping rod to rotate around the fixed frame. Multiple plates clamp the PET sheet body. Heated airflow passes through the drying ring tube and connects to multiple air outlets, drying the PET sheet body. The weight of the clamping rod reduces the workload of the workers. The clamping rod does not obstruct the outside of the PET sheet body, avoiding blind spots during the drying process.
[0004] However, existing technologies still have certain shortcomings in use. For example, existing adhesive drying equipment can usually only dry one side of PET sheets. After one side is dried, it needs to be re-fixed and installed before the other side is dried. The drying efficiency is low. At the same time, the drying process of existing technologies is cumbersome and cannot be applied to mass production lines.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0026] Example:
[0027] Please see Figure 1-3 A PET sheet extrusion production line adhesive drying device includes a drying chamber 1 and a conveyor belt 2. A controller 3 is fixedly installed on the surface of the drying chamber 1, and a drying mechanism 4 is provided in the inner cavity of the drying chamber 1. A feeding trough 5 and a discharging trough 6 are respectively opened on both sides of the drying chamber 1. The conveyor belt 2 is installed in cooperation with the drying chamber 1 through the feeding trough 5 and the discharging trough 6. An air inlet 7 and an air outlet 8 are respectively opened on both sides of the drying chamber 1. An air supply mechanism 9 is provided on the drying chamber 1 at a position relative to the air outlet 8. A humidity sensor 10 is fixedly installed on the inner wall of the drying chamber 1. When the PET sheet adhesive is dried, the PET sheet is placed on the conveyor belt 2 and conveyed to the drying chamber through the feeding trough 5. Inside the drying chamber 1, the drying mechanism 4 is opened by the controller 3, allowing both sides of the PET sheet to be dried simultaneously. The humidity sensor 10 detects the humidity inside the drying chamber 1. When the set value is reached, the air supply mechanism 9 and the air outlet 7 blow air into the drying chamber 1, thereby removing the moisture generated on the surface of the PET sheet during the drying process. By circulating the airflow, the difference between dry and wet surfaces of the PET sheet is reduced, ensuring the uniformity of drying and improving the drying effect. The dried PET sheet is transported to the next step through the discharge chute 6, thus realizing the streamlined processing of PET sheets and improving the efficiency of the entire production line.
[0028] The conveyor belt 2 has multiple protrusions 21 on its surface and multiple ventilation slots 22 on its surface. By setting the protrusions 21, the friction between the PET sheet and the conveyor belt 2 can be increased, preventing the PET sheet from shifting. At the same time, during drying, the PET sheet is lifted up, creating a gap between the PET sheet and the conveyor belt 2, thereby improving the drying effect. By setting the ventilation slots 22, hot air can circulate, drying both sides of the PET sheet and improving the drying efficiency.
[0029] Furthermore, the drying mechanism 4 includes a first heating pipe 41 fixedly installed at the top of the inner cavity of the drying chamber 1, and a second heating pipe 42 fixedly installed at the bottom of the inner cavity of the drying chamber 1. A temperature sensor 43 is installed inside the drying chamber 1. When the PET sheet is transported into the drying chamber 1, the first heating pipe 41 and the second heating pipe 42 are turned on by the temperature sensor 43. The heat generated by the second heating pipe 42 is directly applied to the bottom of the PET sheet through the ventilation slot 22, which can dry both the top and bottom of the PET sheet, thereby improving the drying efficiency of the PET sheet.
[0030] In this drying chamber 1, air guide hoods 44 are fixedly installed on the inner wall of the drying chamber 1 at positions relative to the first heating tube 41 and the second heating tube 42. The air guide hoods 44 are V-shaped. By setting the air guide hoods 44, heat can be concentrated to various positions of the PET sheet, avoiding heat loss, shortening the drying time, and improving the drying efficiency of the PET sheet. A support rod 45 is fixedly connected to the surface of the air guide hood 44, and one end of the support rod 45 is fixedly connected to the inner wall of the drying chamber 1. By setting the support rod 45, the air guide hood 44 can be supported and connected, increasing the stability of the air guide hood 44.
[0031] Furthermore, the air supply mechanism 9 includes a blower pump 91 installed on the side of the drying chamber 1, and an air inlet pipe 92 and a delivery pipe 93 installed on the blower pump 91. One end of the delivery pipe 93 is fixedly connected to the air outlet 7. When blowing air into the drying chamber 1, the blower pump 91 is turned on, and with the connection of the air inlet pipe 92, outside air can be introduced into the interior of the drying chamber 1 through the delivery pipe 93. At the same time, a filter screen is provided at the bottom of the air inlet pipe 92 to prevent dust from contaminating the adhesive on the PET sheet. An air outlet plate 94 is fixedly installed on the inner wall of the drying chamber 1. An air outlet groove 95 is opened on the side of the air outlet plate 94. One end of the delivery pipe 93 passes through the interior of the air outlet groove 95. The air outlet groove 95 is located inside the two air guide hoods 44. By setting the air outlet groove 95, the contact area between the outside airflow and the PET sheet can be increased, thereby carrying away as much moisture generated during the drying process of the PET sheet as possible, ensuring the uniformity of drying and improving the drying effect.
[0032] The drying chamber 1 is fixedly equipped with an air pump 11 on its side. The air outlet pipe of the air pump 11 is fixedly equipped with an exhaust pipe 12, and the air inlet pipe of the air pump 11 is fixedly equipped with an air extraction pipe 13. The air extraction pipe 13 is fixedly sleeved inside the air outlet 8. When the air supply mechanism 9 is opened, in order to realize the air circulation as soon as possible, the air pump 11 is turned on. With the connection of the air extraction pipe 13, the air in the drying chamber 1 can be extracted and discharged to the outside through the exhaust pipe 12, thereby achieving the purpose of quickly removing moisture.

[0034] The above description is only a preferred embodiment of the present utility model.
