Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hot melt filler equipment, and specifically to a hot melt filler device. Background Technology
[0002] Hot melt adhesive melting is the process of heating solid hot melt adhesive to a liquid state. Typically, hot melt adhesive granules are fed into a melting furnace for melting. The melted hot melt adhesive can then be shaped according to production needs. Mechanical intervention is required for feeding during this process, with mechanical tilting being a common method. This method significantly reduces manual intervention and improves production efficiency. Patent number CN202421367356.4 discloses a hot melt adhesive feeding device that uses an electric heating cylinder to feed the hot melt adhesive into a guide cylinder. The process involves heating the granules and simultaneously starting a motor to drive a rotating shaft, which in turn rotates the auger within the guide cylinder. With the support of auxiliary components, the rotating auger ensures uniform conveying of the hot melt adhesive granules. Combined with heating from the electric heating cylinder, this ensures even heating of the granules during conveying, maintaining a consistent temperature at discharge and preventing batch variations or differences in entry time from affecting the uniformity of melting. However, during the use of the hot melt filler equipment, a filter screen is used to filter the material passing through the guide cylinder. Impurities can easily become trapped in the filter screen's mesh, affecting its operation. Therefore, we propose a hot melt filler device. Utility Model Content
[0003] To address the problems in the prior art, this utility model provides a hot-melt filler device.
[0004] The technical solution adopted by this utility model to solve its technical problem is a hot melt filling device, including a furnace body. The feeding end of the outer wall of the furnace body is equipped with a straight pipe for feeding, and a collection box is equipped on the outer periphery of the straight pipe. One end of the straight pipe located inside the box has an opening, and an arc-shaped screen plate that fits the opening is embedded on the outer periphery of the straight pipe. The arc-shaped screen plate is located inside the box. The outer wall surface of the arc-shaped screen plate and the outer wall surface of the straight pipe are equipped with corresponding lugs, and there are multiple sets of lugs. Fastening bolts for limiting and fixing are installed between two sets of lugs. The inner side of the air outlet end of the outer periphery of the box is equipped with a ring frame for support, and the outer wall surface of the ring frame is equipped with a turbine fan for dust collection. The outer wall surface of the box is equipped with a ring seat that communicates with the ring frame, and the outer periphery of the ring seat is screwed with a ring seat for support. The end of the ring seat away from the ring seat is equipped with a dust collection bag, and the outer wall surface of the ring seat is equipped with a convex rod for rotation, and there are multiple sets of convex rods.
[0005] By adopting the above technical solution, during the use of the hot melt filling equipment, the material can be transported into the furnace body for hot melting by the feeding auger inside the straight pipe. The arc-shaped screen plate in the opening on the outer periphery of the straight pipe facilitates the filtering of the passing material, and the impurities in the material can easily fall into the box. Then, the arc-shaped screen plate embedded in the opening can be disassembled by simply unscrewing the fastening bolts on the lug, which is convenient for cleaning or replacement. This allows the arc-shaped screen plate to screen the material more stably and facilitates the hot melting of the material. When impurities in the material fall into the box through the holes of the arc-shaped screen plate, the turbine fan on the outside of the ring frame on the box can operate and suck up the dust mixed in with the impurities, so that the dust is collected and processed. The dust can easily pass through the ring seat and fall into the cloth bag on the outside of the ring seat. The cloth bag facilitates the collection and centralized processing of the dust. Afterwards, the cloth bag can be disassembled simply by unscrewing the ring seat that is screwed on the outer circumference of the ring seat, which makes it easy to process the collected dust. At the same time, the protruding rod on the outer circumference of the ring seat makes the ring seat easier to disassemble and assemble.
[0006] Specifically, a filter screen for protection is fitted at one end of the ring frame near the housing.
[0007] By adopting the above technical solution, the filter plate on the frame can easily intercept non-dust or dust debris, which can reduce the impact of debris on the turbine fan and enable the turbine fan to more stably suck up dust and particulate matter.
[0008] Specifically, the outer wall surface of the box is bolted with a cover plate for maintenance, and a collection tray is inserted into the inner side of the box.
[0009] By adopting the above technical solution, the tray can easily collect the debris filtered by the arc-shaped screen plate, which is convenient for subsequent processing. It can be easily removed by simply pulling the tray. The cover plate on the outside of the box is easy to disassemble and install, making it convenient to replace or clean the arc-shaped screen plate.
[0010] Specifically, the outer wall surface of the tray is fitted with a grille for ventilation.
[0011] By adopting the above technical solution, the grille on the outside of the tray facilitates ventilation, enabling the turbine fan to stably suck up dust and grime.
[0012] Specifically, the top surface of the arc-shaped sieve plate is integrally constructed with convex strips that fit into the inner wall of the opening, and there are two sets of convex strips.
[0013] By adopting the above technical solution, the convex strips on the arc-shaped screen plate and the grooves on the inner wall of the opening fit together, which facilitates the improvement of the tightness of the connection between the arc-shaped screen plate and the opening.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of this application, through the design of straight pipe, box body, opening, arc-shaped screen plate, lug seat and fastening bolts, allows the material to be transported into the furnace body for hot melting during the use of the hot melting filling equipment by the feeding auger inside the straight pipe. The arc-shaped screen plate in the opening on the outer periphery of the straight pipe facilitates the filtration of the passing material, and the impurities in the material can easily fall into the box body. Then, simply unscrew the fastening bolts on the lug seat to disassemble the arc-shaped screen plate embedded in the opening, which is convenient for cleaning or replacement. This allows the arc-shaped screen plate to screen the material more stably and facilitate the hot melting of the material.
[0015] 2. The technical solution of this application, through the design of a ring frame, a turbine fan, a ring seat, a bag body, and a protruding rod, allows the turbine fan on the outside of the ring frame on the box to operate and suck up the dust mixed in with the dust when the impurities in the material fall through the holes of the arc-shaped screen plate into the box. This allows the dust to be centrally processed, and the dust can easily pass through the ring seat and fall into the bag body on the outside of the ring seat. The bag body facilitates the collection and centralized processing of the dust, and the bag body can be disassembled by simply unscrewing the ring seat that is screwed on the outer circumference of the ring seat, making it easy to process the collected dust. At the same time, the protruding rod on the outer circumference of the ring seat makes the ring seat easier to disassemble and assemble. Attached Figure Description

A fastening bolt 7 for limiting and fixing is installed between the ear seats 6; a ring frame 8 for support is installed on the inner side of the air outlet end of the outer periphery of the box body 3, and a turbine fan 9 for dust collection is installed on the outer wall surface of the ring frame 8; a ring seat 10 connected to the ring frame 8 is installed on the outer wall surface of the box body 3, and a ring seat 11 for support is screwed on the outer periphery of the ring seat 10; a dust collection bag body 12 is installed at the end of the ring seat 11 away from the ring seat 10, and a convex rod 15 for rotation is installed on the outer wall surface of the ring seat 11, and there are multiple sets of convex rods 15.
[0020] During use, the material can be conveyed into the furnace body 1 by the feeding auger inside the straight pipe 2 for hot melting. The arc-shaped screen plate 5 in the opening 4 on the outer periphery of the straight pipe 2 can easily filter the passing material, and the impurities in the material can easily fall into the box 3. Then, simply unscrew the fastening bolt 7 on the ear seat 6 to disassemble the arc-shaped screen plate 5 embedded in the opening 4 for easy cleaning or replacement, so that the arc-shaped screen plate 5 can screen the material more stably and facilitate the hot melting of the material. When impurities in the material fall into the box 3 through the holes of the arc-shaped screen plate 5, the turbine fan 9 on the outside of the ring frame 8 on the box 3 can operate and suck up the dust mixed in with the impurities, so that the dust is concentrated and processed. The dust can easily pass through the ring seat 10 and fall into the bag body 12 on the outside of the ring seat 11. The bag body 12 can easily collect the dust and process it in a concentrated manner. In addition, the bag body 12 can be disassembled by simply unscrewing the ring seat 11 that is screwed on the outer periphery of the ring seat 10, which makes it easy to process the collected dust. At the same time, the protruding rod 15 on the outer periphery of the ring seat 11 makes the ring seat 11 easier to disassemble and assemble.
[0021] like Figure 3 As shown, a filter screen 14 for protection is installed at one end of the frame 8 near the housing 3.
[0022] When in use, the filter plate 14 on the frame 8 can easily intercept non-dust or dust debris, which can reduce the impact of debris on the turbine fan 9, and enable the turbine fan 9 to more stably suck up dust and particulate matter.
[0023] like Figure 1 and Figure 3As shown, a cover plate 18 for maintenance is bolted to the outer wall surface of the box 3, and a tray 16 for collection is inserted into the inner side of the box 3.
[0024] When in use, the tray 16 is convenient for collecting the debris filtered by the arc-shaped screen plate 5, which is convenient for subsequent processing. The tray 16 can be pulled out by force. The cover plate 18 on the outside of the box 3 is easy to disassemble and install, which is convenient for replacing or cleaning the arc-shaped screen plate 5.
[0025] like Figure 1 and Figure 3 As shown, the outer wall surface of the tray 16 is fitted with a grille 17 for ventilation.

[0028] When in use, the protrusions 13 on the arc-shaped screen plate 5 fit into the grooves on the inner wall of the opening 4, which facilitates the tightness of the connection between the arc-shaped screen plate 5 and the opening 4.
[0029] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. During the use of the hot-melt filling equipment, the controller on the outer periphery of the furnace body 1 can control the feeding auger inside the straight pipe 2 to transport the material into the furnace body 1 for hot melting. The arc-shaped screen plate 5 in the opening 4 on the outer periphery of the straight pipe 2 facilitates the filtration of the passing material, and impurities in the material easily fall into the housing 3. Then, simply unscrew the fastening bolts 7 on the lug 6 to disassemble the arc-shaped screen plate 5 embedded in the opening 4 for easy cleaning or replacement. This allows the arc-shaped screen plate 5 to more stably screen the material, facilitating the material intake. During the hot-melt process, when impurities in the material fall into the housing 3 through the holes of the arc-shaped screen plate 5, the turbine fan 9 on the outer side of the ring frame 8 on the housing 3 can operate and suck up the dust mixed in with the impurities, so that the dust is concentrated and processed. The dust can easily pass through the ring seat 10 and fall into the bag body 12 on the outer side of the ring seat 11. The bag body 12 can easily collect the dust and process it in a concentrated manner. In addition, the bag body 12 can be disassembled by simply unscrewing the ring seat 11 that is screwed on the outer circumference of the ring seat 10, which is convenient for processing the collected dust. At the same time, the protruding rod 15 on the outer circumference of the ring seat 11 makes the ring seat 11 easier to disassemble and assemble, thus making the hot-melt filling equipment more convenient to use.
