Description

Technical Field

[0001] This utility model relates to the technical field of glass bottle drying equipment, and in particular to a hot air dryer for cosmetic glass bottles. Background Technology

[0002] In the cosmetics production process, glass bottles serve as the core packaging container, bearing the dual functions of protecting the product and enhancing the brand image. The cleanliness and dryness of their surface not only directly affect the quality and safety of the product, but also relate to the sealing after filling and the shelf display effect.

[0003] The hot air dryer for cosmetic glass bottles mainly consists of a conveyor, a fan, a heating device, and a drying hood. The conveyor transports the glass bottles via a conveyor belt, the fan draws in outside air, and after being heated by the heating elements in the heating device, hot air is blown out by the drying hood. The glass bottles move on the conveyor belt and pass through the hot air zone in sequence. The hot air carries away the moisture on the surface of the bottle, thus achieving drying.

[0004] However, the glass bottle positioning devices in existing dryers lack flexibility, mostly consisting of fixed-size rods and limiting structures that cannot adapt to glass bottles of different diameters. When producing products of various specifications, companies need to frequently replace the entire drying equipment or invest a lot of manpower in complex mechanical adjustments. This is not only costly but also prone to problems such as the glass bottles shaking and tipping over during the drying process due to inaccurate positioning, resulting in uneven drying and equipment damage. This greatly restricts the efficiency and diversity requirements of cosmetic packaging production. Furthermore, the filtration system design is inadequate, often using non-removable or difficult-to-remove filter structures. When the filter becomes clogged with dust, it takes a lot of time to disassemble the entire air duct for cleaning, seriously affecting the continuous operating efficiency of the equipment. Some equipment even lacks activated carbon adsorption function, failing to effectively remove odors from the drying air, resulting in residual impurities or odors in the glass bottles, affecting product quality.

[0005] Therefore, a hot air dryer for cosmetic glass bottles is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a hot air dryer for cosmetic glass bottles, which aims to improve the problem that the existing technology cannot adapt to glass bottles of different diameters and that the filter screen needs to be disassembled and cleaned in a lot of time after it becomes clogged with dust.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot air dryer for cosmetic glass bottles, including a conveyor, a conveyor belt inside the conveyor, a mounting seat on the surface of the conveyor belt, a mounting head threadedly connected to the upper side of the mounting seat, a rod fixedly connected to the upper side of the mounting head, fixing plates fixedly connected to the upper sides of the conveyor, an adjusting rod threadedly connected to the inside of the fixing plate, a limit rod fixedly connected to the inner side of the adjusting rod, a rotating block fixedly connected to the side of the adjusting rod away from the limit rod, a fixing frame fixedly installed on the upper side of the conveyor, a filter box fixedly installed on the upper side of the fixing frame, a filter assembly inside the filter box, a fan fixedly installed on the right side of the filter box, and a heating and blowing assembly on the side of the filter box away from the fan.

[0008] Furthermore, the filter assembly includes a sealing plate, which is disposed on the filter box. A sealing gasket is fixedly installed on the lower side of the sealing plate, and a filter screen and an activated carbon screen are fixedly installed on the lower side of the sealing plate. A slot is provided at the bottom of the filter box.

[0009] Furthermore, the heating and blowing assembly includes a heating box, which is fixedly installed on the side of the filter box away from the fan. The heating box is connected to the filter box, and a heating wire is fixedly installed inside the heating box. A connecting pipe is fixedly connected to the left side of the heating box, and a drying hood is fixedly connected to the side of the connecting pipe away from the heating box.

[0010] Furthermore, the filter screen is positioned directly to the right of the activated carbon mesh, and the filter screen and the lower side of the activated carbon mesh are slidably connected inside the slot.

[0011] Furthermore, the lower sides of the filter screen and activated carbon screen are slidably connected inside the slot.

[0012] Furthermore, the drying hood is disposed on both sides inside the fixed frame, and the limiting rod is disposed on the lower side of the drying hood.

[0013] Furthermore, the limiting rod is slidably connected to the upper side of the conveyor.

[0014] Furthermore, a controller is fixedly installed on the front side of the fixed frame, and the controller is electrically connected to the conveyor, the fan and the heating wire.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by using a threaded connection between the insert rod and the mounting base, and in conjunction with a horizontally adjustable limiting rod, it is possible to quickly adapt to glass bottles of different diameters. By rotating the rotating block to drive the adjusting rod, the limiting rod can accurately position the bottle body, preventing shaking during the drying process. At the same time, replacing the insert rod only requires a threaded turning operation, without the need for additional tools. Compared with the traditional fixed insert rod design, this greatly improves production flexibility.

[0017] 2. In this utility model, by setting a detachable filter screen and activated carbon screen inside the filter box, and utilizing the cooperation of the slot and the sealing plate, the filter screen assembly can be quickly disassembled and assembled. When it is necessary to clean or replace the filter screen, the filter screen can be pulled out as a whole simply by removing the sealing plate, without the need for complicated tools or disassembling pipes. Compared with the traditional dryer that requires disassembling the entire air duct for maintenance, it significantly shortens the maintenance time. Moreover, the design of the sealing gasket ensures that there is no air leakage during the filtration process, thereby improving the purification efficiency. Attached Figure Description

[0027] 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.

[0028] Reference Figures 1-3 An embodiment of this utility model provides a hot air dryer for cosmetic glass bottles, including a conveyor 1, a conveyor belt 2 inside the conveyor 1, a mounting seat 3 on the surface of the conveyor belt 2, a mounting head 4 threadedly connected to the upper side of the mounting seat 3, a plug rod 5 fixedly connected to the upper side of the mounting head 4, fixing plates 6 fixedly connected to the upper two sides of the conveyor 1, an adjusting rod 7 threadedly connected to the inside of the fixing plate 6, a limit rod 8 fixedly connected to the inner side of the adjusting rod 7, the limit rod 8 slidably connected to the upper side of the conveyor 1, a rotating block 9 fixedly connected to the side of the adjusting rod 7 away from the limit rod 8, a fixing frame 10 fixedly installed on the upper side of the conveyor 1, a filter box 14 fixedly installed on the upper side of the fixing frame 10, a filter assembly 11 inside the filter box 14, a fan 12 fixedly installed on the right side of the filter box 14, and a heating and blowing assembly 13 on the side of the filter box 14 away from the fan 12.

[0029] Specifically, the open end of the glass bottle is vertically inserted into the top of the insert rod 5. The insert rod 5 is threadedly connected to the mounting base 3 via the mounting head 4, ensuring a stable and wobbly position. Then, rotating the rotating block 9 causes the adjusting rod 7 to rotate within the fixed plate 6. The limiting rod 8 on the inner side of the adjusting rod 7 moves laterally accordingly. The distance between the two limiting rods 8 is adjusted according to the diameter of the glass bottle, allowing them to lightly touch the outer wall of the bottle for stable positioning. When drying glass bottles of different sizes, the insert rod 5 is replaced first. Since the mounting base 3 and the mounting head 4 are threadedly connected, rotating the insert rod 5 counterclockwise will remove it from the bottle. Remove from mounting base 3. Select the appropriate insertion rod 5 according to the bottle mouth size of the new glass bottle, align its mounting head 4 with the threaded hole of mounting base 3, and turn clockwise until tightened. Then, turn the rotating block 9 again to drive the adjusting rod 7 to rotate, so that the limiting rod 8 moves inward or outward until the distance between the two limiting rods 8 matches the diameter of the new glass bottle. Lightly touch the bottle body to achieve positioning, so that the device can quickly adapt to glass bottles of different diameters to meet diverse drying needs, while ensuring that the glass bottle remains stable during the drying process and avoiding uneven contact of hot air due to shaking.

[0030] Reference Figures 4-7 The filter assembly 11 includes a sealing plate 113, which is disposed on the filter box 14. A sealing gasket 114 is fixedly installed on the lower side of the sealing plate 113. A filter screen 111 and an activated carbon screen 112 are fixedly installed on the lower side of the sealing plate 113. The lower sides of the filter screen 111 and the activated carbon screen 112 are slidably connected to the inside of the slot 115. The slot 115 is provided at the bottom of the filter box 14. The filter screen 111 is disposed on the right side of the activated carbon screen 112. The lower sides of the filter screen 111 and the activated carbon screen 112 are slidably connected to the inside of the slot 115. The heating and blowing assembly 13 includes a heating box 1. 32. The heating box 132 is fixedly installed on the side of the filter box 14 away from the fan 12. The heating box 132 is connected to the filter box 14. The heating wire 131 is fixedly installed inside the heating box 132. The left side of the heating box 132 is fixedly connected to the connecting pipe 133. The side of the connecting pipe 133 away from the heating box 132 is fixedly connected to the drying hood 134. The drying hood 134 is set on both sides inside the fixed frame 10. The limiting rod 8 is set on the lower side of the drying hood 134. The controller 15 is fixedly installed on the front side of the fixed frame 10. The controller 15 is electrically connected to the conveyor 1, the fan 12 and the heating wire 131.

[0031] Specifically, after the limit is completed, the controller 15 is activated, and the conveyor belt 2 of the conveyor 1 starts to operate, driving the mounting base 3 to move along the conveying direction. At the same time, the fan 12 starts, drawing outside air into the filter box 14. The air first passes through the filter screen 111 to remove dust, debris, and other particulate impurities, and then passes through the activated carbon screen 112 to adsorb odors and trace pollutants in the air. The purified air enters the heating box 132. The heating wire 131 in the heating box 132 heats up after being energized, heating the air to the set temperature. The hot air is evenly blown out from the drying hood 134 through the connecting pipe 133, cleaning and drying the surface of the glass bottles conveyed to the bottom of the drying hood 134. The conveyor belt 2 continues to operate. The glass bottle passes through the hot air zone sequentially to evaporate and dry the surface moisture. When it is necessary to disassemble the filter screen 111 and activated carbon screen 112, first turn off the power of the equipment through the controller 15 to ensure that the fan 12, heating wire 131 and conveyor 1 stop running; then unscrew the fixing bolts of the sealing plate 113 and the filter box 14, and pull the sealing plate 113 upward to separate it from the filter box 14, while taking out the sealing gasket 114; then smoothly pull out the filter screen 111 and activated carbon screen 112 under the sealing plate 113 along the direction of the slot 115 at the bottom of the filter box 14 for cleaning or replacement; after completion, reinsert the filter screen assembly into the slot 115 to ensure the filtration effect.

[0032] Working principle: When using this device, firstly, insert the glass bottle into the insertion rod 5. By rotating the rotating block 9, the adjusting rod 7 is rotated, causing the limiting rod 8 to move laterally, thereby adjusting the limiting position of the glass bottle to ensure its stability during the drying process. After the controller 15 is started, the conveyor belt 2 of the conveyor 1 runs, driving the mounting base 3 and the glass bottle to move. At the same time, the fan 12 draws outside air into the filter box 14. The air first passes through the filter screen 111 to remove dust and other particulate impurities, and then passes through the activated carbon screen 112 to adsorb odors, thus purifying the air. The purified air enters the heating box 132, is heated into hot air by the heating wire 131, and blown out from the drying hood 134 through the connecting pipe 133 to evenly dry the surface of the glass bottle. During the drying process, the conveyor belt 2 continuously transports the glass bottle, allowing it to pass through the hot air area in sequence to complete the drying operation.

[0033] When different types of glass need to be dried, the insert rod 5 can be rotated because the mounting base 3 and the mounting head 4 are threaded together, so the insert rod 5 can be disassembled. By rotating the mounting head 4 of the new-size insert rod 5 inside the mounting base 3, and at the same time rotating the rotating block 9, the rotating block 9 drives the adjusting rod 7 to rotate, which drives the limiting rod 8 to move inward, thus limiting the glass bottle of the new size to meet different needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
