Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of material filling devices, specifically a hot melt glue machine that facilitates material filling. Background Technology
[0002] A hot melt adhesive machine typically consists of a silo, a heating system, a conveying system, and nozzles. The silo stores the hot melt adhesive, heats it to a suitable flow state through the heating system, and then conveys it to the nozzles for bonding.
[0003] An automatic feeding device for a hot melt glue machine, with announcement number CN213435418U, is disclosed. It belongs to the technical field of feeding devices. The automatic feeding device for the hot melt glue machine includes a storage tank, a tank body, and a melting machine box. The top of the tank body is fixed with a tank cover by bolts. A conveying mechanism is provided on the top of the tank body. A crushing mechanism is provided inside the tank body. A fixed base is fixed to the bottom of the tank body by bolts. A pulse dust removal mechanism is provided on one side of the outer wall of the tank body. A gravity sensor is fixed to the inner wall of the tank body by bolts. A controller is fixed to the outer circumference of one side of the tank body by bolts.
[0004] The aforementioned device detects the liquid level inside the hot melt adhesive container using a liquid level sensor inside the discharge pipe. When the liquid level inside the container is too low, the liquid level sensor transmits a signal to the controller, which then controls the delivery of hot melt adhesive, thus achieving automatic feeding. This device relies on external equipment, such as the liquid level sensor and controller, to perform the feeding task. This means that if the external equipment malfunctions, the system may not function properly, affecting production efficiency. Secondly, the accuracy of the liquid level sensor is crucial to the system's stability. If the sensor's response is not sensitive enough or if errors occur, it may lead to untimely adhesive replenishment, or even excessive or insufficient adhesive, thus affecting the quality of the final product. Furthermore, while the automatic feeding system can improve work efficiency, it also increases the system's complexity. If problems arise in actual production, maintenance and debugging may be more cumbersome and costly. Therefore, improvements or optimizations are needed. Utility Model Content

Detailed Implementation
[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] like Figures 1 to 5 As shown, this utility model provides a hot melt adhesive machine that facilitates material addition, comprising:
[0027] Support frame 1, and tank 2 is fixedly installed on the inner wall of support frame 1;
[0028] Tank 2, from top to bottom, consists of an addition tank 21, an addition and mixing tank 22 and a hot melt tank 23. A conveying pipe 231 is fixedly installed on the outer wall of the hot melt tank 23.
[0029] An automatic feeding mechanism is installed inside the tank 2;
[0030] The automatic dispensing mechanism includes a drive assembly, a cleaning assembly, and a filling assembly. The filling assembly includes a partition 222 fixedly installed on the inner wall of the tank 2. A telescopic channel 2212 is fixedly installed at the top center of the partition 222. A movable plate 221 is fixedly installed at the top of the telescopic channel 2212. Multiple connecting rods 4 are fixedly installed at the top of the movable plate 221, and connecting blocks 41 are fixedly installed at the top of each of the multiple connecting rods 4. The multiple connecting blocks 41 are all bent to fit the top of the mixing tank 22, and the multiple connecting rods 4 are equidistantly distributed with the axis of the mixing tank 22 as the center. The drive assembly includes a motor 3 fixedly installed on the top of the support frame 1. A rotating rod 31 is fixedly installed on the output shaft of the motor 3, and the bottom end of the rotating rod 31 extends into the hot melt tank 23. The bottom of the movable plate 221 and the top of the partition 222 are connected by multiple springs 2211. The system is designed with multiple springs 2211 arranged in a circular array at equal intervals around the axis of the mixing tank 22. The cleaning components include a triangular cleaner 311 and a four-corner rotator 312 fixedly sleeved on the outer wall of the rotating rod 31. The triangular cleaner 311 is located on the inner wall of the mixing tank 21 and is slidably connected to the inner wall of the mixing tank 21. The four-corner rotator 312 is located inside the mixing tank 22, and four telescopic columns 3121 are provided at the bottom of the four four-corner rotator 312. Four stirring columns 3122 are fixedly installed on the outer wall of the four telescopic columns 3121, and the bottom of the four telescopic columns 3121 is rotatably connected to the top of the moving plate 221. An auger 313 is fixedly installed on the outer wall of the rotating rod 31 and is rotatably connected to the telescopic channel 2212. The inner surfaces of the mixing tank 21, the mixing tank 22, and the hot melt tank 23 are all coated with a nano non-stick coating.
[0031] The above solution achieves automatic addition of hot melt adhesive raw materials through the design of the filler assembly via an automatic adding mechanism. By automating the conveying, mixing, and transporting of hot melt adhesive raw materials, the tediousness of manual operation is avoided, making the whole process more efficient and convenient. Especially under the action of the connecting block 41, driven by its own weight, the connecting rod 4 and the moving plate 221 automatically adjust the size of the channel, ensuring the smooth flow and accurate filling of the hot melt adhesive material; driven by the motor 3, the triangular cleaner 311 can effectively scrape off the hot melt adhesive material adhering to the inner wall of the addition tank 21, thereby reducing the possibility of hot melt adhesive material adhesion and reducing the workload and difficulty in the cleaning process; the four-corner rotator 312 drives the telescopic column 3121 and the stirring column 3122 to rotate, which can effectively stir the hot melt adhesive material in the addition mixing tank 22, avoiding processing problems caused by material sticking or unevenness; when the hot melt adhesive material in the addition mixing tank 22 is transported to the hot melt tank 23, the spring 2211 will rebound according to the weight and pressure of the hot melt adhesive material, automatically adjusting the position of the moving plate 221; the automated compression and rebound design can accurately control the opening and closing of the feeding channel, ensuring the stable operation of the system; through the rotation of the auger 313, the hot melt adhesive material can be evenly transported to the hot melt tank 23, ensuring the maximum utilization rate of the material.
[0032] Working principle and usage process of this utility model:
[0033] Initially, with the elastic support of spring 2211, the height of connecting block 41 is at the middle of the filling tank 21, so that the channel between the filling tank 21 and the mixing tank 22 is open. Hot melt adhesive material is put into the filling tank 21, and the hot melt adhesive material can smoothly pass through the support frame 1 into the mixing tank 22. As the hot melt adhesive material continuously enters the mixing tank 22, the weight of the hot melt adhesive material itself causes the connecting block 41 to drive multiple connecting rods 4 to move downward. The connecting block 41 drives the moving plate 221 to move together. The moving plate 221 squeezes the spring 2211 and the telescopic channel 2212 to make them contract, so that the gap between the filling tank 21 and the mixing tank 22 becomes smaller and smaller. When enough hot melt adhesive material enters the mixing tank 22, the connecting block 41 is located in the middle of the channel between the filling tank 21 and the mixing tank 22, which can prevent the hot melt adhesive material from continuing to enter the mixing tank 22.
[0034] Then start motor 3. The output shaft of motor 3 rotates and drives the triangular cleaner 311, the four-corner rotator 312 and the auger 313 to rotate in sequence. The rotation of the triangular cleaner 311 scrapes off the hot melt adhesive material on the inner wall of the addition tank 21 to prevent the hot melt adhesive material from adhering to the inner wall of the addition tank 21 and increasing the cleaning burden.
[0035] The four corner rotators 312 drive the four telescopic columns 3121 and the stirring column 3122 to rotate, thereby stirring and breaking up the hot melt adhesive material inside the mixing tank 22 to prevent sticking.
[0036] By rotating the auger 313, the hot melt adhesive raw material in the mixing tank 22 can be evenly transported to the hot melt tank 23 for heating and then transported to the next stage through the conveying pipe 231.
[0037] The continuous conveying by the auger 313 reduces the amount of hot melt adhesive material in the mixing tank 22, thereby reducing the compression of the spring 2211. This causes the spring 2211 to rebound, driving the moving plate 221, connecting rod 4, and connecting block 41 to move upward. Since the telescopic column 3121 can extend and retract, the vertical movement of the moving plate 221 does not affect the rotation and mixing operation of the telescopic column 3121 and the stirring column 3122. The rise of the connecting block 41 reopens the feeding channels of the mixing tank 22 and the adding tank 21, allowing the hot melt adhesive material in the adding tank 21 to smoothly enter the mixing tank 22 for automatic filling.
