Description

Technical Field

[0001] This utility model relates to a glue supply structure for a hot melt glue machine, and belongs to the technical field of hot melt glue machines. Background Technology

[0002] Hot melt glue machines are mainly used for automated applications of hot melt glue spraying, scraping, rolling, coating, and dispensing. When using a hot melt glue machine, a glue supply structure is required, which is generally a glue tank. When using it, you only need to pour the hot melt glue block into the glue tank and heat it to melt it before you can start the operation.

[0003] However, existing glue buckets still have many problems. When using them, hot melt glue blocks generally need to be melted and filtered. Because there are some impurities and gel particles inside the hot melt glue blocks, the existing glue buckets do not have a filtration function. Long-term use may cause the glue inside the bucket to clog the spray gun when it is delivered to the spray gun, making it impossible to apply glue normally. Secondly, glue buckets are generally fixed, and cleaning requires operation on the hot melt glue machine, which is difficult. In view of the above shortcomings, this utility model proposes a glue supply structure for a hot melt glue machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hot melt glue machine glue supply structure to solve the existing problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot melt glue machine supply structure, comprising a frame, an outer casing assembly on the top surface of the frame, and a base assembly connected to the bottom surface of the outer casing assembly cavity. A constant temperature heater is provided on the top surface of the base assembly, and a material tank is elastically abutted against the top surface of the constant temperature heater. The lower end of the material tank is threadedly sealed to the base assembly, and a hot melt frame is placed on the top surface of the material tank. A hot melt heating lamp is provided along the upper periphery of the outer casing assembly cavity. A first discharge pipe connected to the material tank is threadedly connected to the middle of the bottom surface of the base assembly, and a valve is connected to the first discharge pipe.

[0006] A further improvement is that the outer box assembly includes an outer box body, the top surface of which is hinged with a box cover, and the bottom surface of the outer box body has an opening in the middle.

[0007] A further improvement is that the base assembly includes a base body, and a threaded locking hole is provided in the center of the top surface of the base body, and a discharge screw hole is provided in the center of the bottom surface of the threaded locking hole. An annular buffer groove is provided around the top surface of the base body, and multiple springs and annular support plates are movably sleeved in the annular buffer groove.

[0008] A further improvement is that the material tank includes a material tank body, and a second discharge pipe is connected to the middle of the bottom surface of the material tank body. A sealing ring is embedded around the bottom surface of the second discharge pipe. A material rack clamping edge for holding the hot melt rack is provided around the top surface of the material tank body. Multiple twisting blocks are provided on the left and right sides of the top surface of the material rack clamping edge.

[0009] A further improvement is that the hot melt frame includes a hot melt frame body, and the top surface of the hot melt frame body has multiple filter holes arranged in a circular array, and the periphery of the top surface of the hot melt frame body is provided with a leak-proof edge, and the periphery of the bottom surface of the hot melt frame body is provided with a sleeve edge.

[0010] A further improvement is that the frame is fixedly mounted on the hot melt glue machine, and the other end of the first discharge pipe is connected to the hot melt glue machine.

[0011] The beneficial effects of the utility model are:

[0012] This utility model provides a glue supply structure for a hot melt glue machine. Through the structural combination design of a frame, outer casing assembly, base assembly, constant temperature heater, material tank, hot melt frame, hot melt heating lamp, first discharge pipe, and valve, a glue supply structure for a hot melt glue machine is formed. The filter holes on the hot melt frame, in conjunction with the leak-proof edge, filter the hot melt glue block after it has been melted into a liquid state at high temperature by the hot melt heating lamp and prevent side leakage. The constant temperature heater maintains a constant temperature for heating the liquid hot melt glue in the material tank to prevent re-condensation. Furthermore, the threaded sealing connection between the material tank and the base assembly, and the buffering design between the constant temperature heater and the material tank, allow for easy assembly and disassembly of the material tank with simple rotation. Additionally, the hot melt frame is designed to fit over the top of the material tank, allowing for easy removal of the frame to clean impurities and glue particles, making it highly practical.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1-5 The present invention provides a schematic diagram of the adhesive supply structure of a hot melt glue machine. The structure includes a frame 1, with an outer casing 2 on the top surface of the frame 1. A base assembly 3 is connected to the bottom surface of the outer casing 2. A constant temperature heater 4 is mounted on the top surface of the base assembly 3. A material tank 5 is elastically abutted against the top surface of the constant temperature heater 4. The lower end of the material tank 5 is threadedly sealed to the base assembly 3. A hot melt frame 6 is placed on the top surface of the material tank 5. A hot melt heating lamp 7 is arranged around the upper periphery of the outer casing 2. A first discharge pipe 8, connected to the material tank 5, is threadedly connected to the middle of the bottom surface of the base assembly 3. A valve 9 is connected to the first discharge pipe 8.

[0020] The outer box assembly 2 includes an outer box body 21, and a box cover 22 is hinged to the top surface of the outer box body 21, and an opening 23 is provided in the middle of the bottom surface of the outer box body 21.

[0021] The base assembly 3 includes a base body 31, and a threaded locking port 32 is provided in the middle of the top surface of the base body 31, and a discharge screw port 33 is provided in the middle of the bottom surface of the threaded locking port 32. An annular buffer groove 34 is provided around the top surface of the base body 31, and multiple springs 35 and an annular support plate 36 are movably sleeved in the annular buffer groove 34.

[0022] The material tank 5 includes a material tank body 51, and a second discharge pipe 52 is connected to the middle of the bottom surface of the material tank body 51. A sealing ring 53 is embedded around the bottom surface of the second discharge pipe 52. A material rack clamping edge 54 for holding the hot melt frame 6 is provided around the top surface of the material tank body 51. Multiple twisting blocks 55 are provided on the left and right sides of the top surface of the material rack clamping edge 54.

[0023] The hot melt frame 6 includes a hot melt frame body 61, and the top surface of the hot melt frame body 61 is provided with a plurality of filter holes 62 in a circular array, and the periphery of the top surface of the hot melt frame body 61 is provided with a leak-proof edge 63, and the periphery of the bottom surface of the hot melt frame body 61 is provided with a sleeve edge 64.

[0024] Working principle:

[0025] In use, open the lid 22 and place the hot melt adhesive block on the top surface of the hot melt frame body 61. At this time, the hot melt heating lamp 7 is at the same level as the hot melt adhesive block. Then, the hot melt heating lamp 7 is activated to heat at high temperature, causing the hot melt adhesive block to melt into liquid and flow out from each filter hole 62. Impurities and gel particles in the hot melt adhesive block will remain on the top surface of the hot melt frame body 61, and the anti-leakage edge 63 can prevent the liquid hot melt adhesive from leaking to the side. Then, the liquid hot melt adhesive flows into the material tank body 51. Then, the constant temperature heater 4 heats the liquid hot melt adhesive in the material tank body 51 at a constant temperature of 50-70 degrees Celsius, which can prevent the liquid hot melt adhesive from solidifying again. Then, open the valve 9 to allow the liquid hot melt adhesive in the material tank body 51 to flow out and supply adhesive to the hot melt glue machine.

[0026] When cleaning the tank body 51, open the cover 22, then rotate the torsion block 55 to disengage the threaded connection between the threaded lock 32 and the second discharge pipe 52, and disengage the buffer between the top surface of the constant temperature heater 4 and the bottom surface of the tank body 51, so that the tank 5 and the hot melt rack 6 can be directly taken out for external cleaning.
