Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a hot melt adhesive particle drying device. Background Technology
[0002] In the production process of hot melt adhesive, the hot melt adhesive is extruded and cut into blocks by an extruder and then cooled and shaped to ensure its physical properties and appearance quality. In the existing technology, the cooling device for hot melt adhesive is usually a water cooling device. After the hot melt adhesive is cooled and shaped, it needs to be dried.
[0003] Existing hot melt adhesive drying equipment uses rotating rods, spiral blades, and heating rods to dry evenly, and is equipped with a sieve plate. The stirring rod inside the drying cylinder has a brush structure to prevent particles from getting stuck in the gaps and improve drying uniformity.
[0004] However, the drying device has a perforated mesh plate underneath the bed, and an air duct below the mesh plate. Hot air from the air duct passes through the mesh plate and heats the hot melt adhesive, removing moisture. Existing hot melt adhesive granule drying devices, due to the relatively high thickness of the hot melt adhesive, exhibit significant differences in the dehydration rate between the lower and middle layers of the drying bed. The lower layer dehydrates faster, while the upper layer dehydrates slower, increasing drying time, wasting more energy, and damaging the structure of the hot melt adhesive. Utility Model Content
[0005] The purpose of this utility model is to provide a hot melt adhesive granule drying device to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: it includes a feeding shell and a feeding machine installed in the feeding shell, and also includes a drying shell and a feeding device disposed in the drying shell. A connecting cover is connected to the top surface of one side of the drying shell, and the top of the connecting cover is connected to the feeding shell. A pre-drainage shell is provided on the feeding shell, and a water removal device is provided inside the pre-drainage shell. A hot air drying shell is provided on the drying shell, and a drying device is provided inside the hot air drying shell.
[0006] The dewatering device includes a compressor installed in the pre-dewatering shell and a filter device set at the top of the pre-dewatering shell. The output end of the compressor is connected to several air nozzles, one end of which is inserted into the feeding shell.
[0007] It should be noted in the solution that the air drying device includes a hot air drying shell connected to the air drying shell and several fans installed inside the hot air drying shell. Above the fans is a filter fixedly connected to the hot air drying shell, and below the fans is a heat pipe fixedly connected to the hot air drying shell.
[0008] It should be noted in the solution that a first baffle and a second baffle are fixedly connected inside the connecting cover, and the first baffle is located above the second baffle.
[0009] It should be noted in the design that the end of the first baffle facing the second baffle is provided with a movable baffle.
[0010] It should be noted in the solution that the drying shell has a discharge port connected to the drying shell at one end away from the feeding shell, and a feeding plate is provided inside the drying shell. One end of the feeding plate abuts against one end of the feeding device, and the other end of the feeding plate abuts against the discharge port.
[0011] Compared with the prior art, the hot melt adhesive granule drying device provided by this utility model has at least the following beneficial effects:
[0012] (1) By setting up a dehydration device and an air-drying device, in actual use, the hot melt adhesive particles first enter the feeding shell and are conveyed to the connecting cover by the feeding machine. During the conveying process, the dehydration device is activated, which blows most of the moisture off the surface of the hot melt adhesive particles. After the first dehydration treatment, the hot melt adhesive particles enter the air-drying shell and fall onto the feeding device. The feeding device is activated to convey the hot melt adhesive particles, and the air-drying device is activated to air-dry the hot melt adhesive particles. After two dehydration treatments, the moisture on the hot melt adhesive particles can be effectively evaporated without damaging the structure of the hot melt adhesive particles.
[0013] (2) With the setting of the first baffle, when the hot melt adhesive particles enter the connecting cover, they first fall onto the first baffle, and then fall onto the second baffle. After passing through the gap between the first baffle and the second baffle, they enter the drying shell. By adjusting the movable baffle at the end of the first baffle, the rate at which the hot melt adhesive particles enter the drying shell can be controlled, which can ensure that the hot melt adhesive particles are evenly distributed and that the hot melt adhesive particles can be dried.

[0017] 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.
[0018] Please see Figure 1-2 A hot melt adhesive granule drying device includes a feeding shell 1 and a feeding machine 6 installed inside the feeding shell 1. The device further includes a drying shell 2 and a feeding device 12 disposed inside the drying shell 2. A connecting cover 4 is connected to the top surface of one side of the drying shell 2, and the top of the connecting cover 4 is connected to the feeding shell 1. A pre-drainage shell 5 is provided on the feeding shell 1, and a dehydration device is provided inside the pre-drainage shell 5. A hot air drying shell is provided on the drying shell 2, and a drying device is provided inside the hot air drying shell.
[0019] With the addition of a dehydration device and a drying device, in actual use, the hot melt adhesive particles first enter the feeding housing 1 and are then conveyed to the connecting cover 4 by the feeding machine 6. During the conveying process, the dehydration device is activated, blowing away most of the moisture from the surface of the hot melt adhesive particles. The moisture that leaves the surface of the hot melt adhesive particles is collected below the feeding machine 6 for easy collection. After the first dehydration treatment, the hot melt adhesive particles enter the drying housing 2 through the connecting cover 4. The hot melt adhesive particles fall onto the feeding device 12, which is then activated to convey the hot melt adhesive particles. The drying device is then activated to dry the hot melt adhesive particles. Through two dehydration treatments, the moisture on the hot melt adhesive particles can be effectively evaporated without damaging the structure of the hot melt adhesive particles.
[0020] Furthermore, referring to Figure 1-2 As shown, it is worth noting that the water removal device includes a compressor 8 installed in the pre-water removal shell 5 and a filter device 7 set at the top of the pre-water removal shell 5. The output end of the compressor 8 is connected to several air nozzles 9, and one end of the air nozzles 9 is inserted into the feeding shell 1.
[0021] With the dehydration device in place, during actual use, the hot melt adhesive particles are conveyed to the connecting cover 4 by the feeder 6. During the conveying process, the dehydration device is activated. The compressor 8 draws in the air filtered by the air nozzle 9 and discharges it through the air nozzle 9. Several air nozzles 9 work together to blow away the moisture on the surface of the hot melt adhesive particles on the feeder 6. After the first dehydration treatment, the subsequent drying time can be effectively reduced.
[0022] Furthermore, referring to Figure 1-2As shown, it is worth noting that the air drying device includes a hot air drying shell connected to the air drying shell 2 and several fans 13 installed inside the hot air drying shell. Above the fans 13 is a filter 15 fixedly connected to the hot air drying shell, and below the fans 13 is a heat pipe 14 fixedly connected to the hot air drying shell. The filter 15 is a high-efficiency air filter, and the heat pipe 14 is a finned electric heating tube.
[0023] With the drying device in place, when in use, the heat pipe 14 and fan 13 are turned on. The fan 13 blows the air filtered by the filter 15 onto the feeding device 12. The air is heated by the heat pipe 14 as it passes through the heat pipe 14. The hot air passes through the hot melt adhesive particles on the feeding device 12 and carries away the residual moisture on the hot melt adhesive particles, which can effectively dry the hot melt adhesive particles.
[0024] Furthermore, referring to Figure 1-2 As shown, it is worth noting that the connecting cover 4 is fixedly connected with a first baffle 10 and a second baffle 11 that are inclined. The first baffle 10 is located above the second baffle 11, and the end of the first baffle 10 facing the second baffle 11 is provided with a movable baffle.
[0025] With the setting of the first baffle 10, when the hot melt adhesive particles enter the connecting cover 4, they first fall onto the first baffle 10, and then fall onto the second baffle 11. After passing through the gap between the first baffle 10 and the second baffle 11, they enter the drying shell 2. By adjusting the movable baffle at one end of the first baffle 10, the speed at which the hot melt adhesive particles enter the drying shell 2 can be controlled, which can ensure that the hot melt adhesive particles are evenly distributed and that the hot melt adhesive particles can be dried.
[0026] Furthermore, referring to Figure 1-2 As shown, it is worth noting that the drying shell 2 is provided with a discharge port 16 connected to the drying shell 2 at one end away from the feeding shell 1. The drying shell 2 is provided with a feeding plate 17. One end of the feeding plate 17 abuts against one end of the feeding device 12, and the other end of the feeding plate 17 abuts against the discharge port 16.
[0027] With the inlet and outlet 16 set, after drying, the hot melt adhesive particles enter the outlet 16 through the feeding plate 17, which can effectively discharge the drying shell 2.
[0028] The above describes a hot melt adhesive particle drying device provided by this utility model. Specific preferred embodiments have been used to illustrate the principle and implementation of this utility model. These embodiments are only used to help understand the principle and core idea of this utility model. It should be noted that for those skilled in the art, the implementation schemes in the above embodiments can be further combined or replaced without departing from the design concept of this utility model, and several improvements and modifications can be made to this utility model. These improvements and modifications also fall within the protection scope of the claims of this utility model.
