Description

Technical Field

[0001] This application relates to the technical field of feed guiding structures, and in particular to a feed guiding structure for a hot melt machine. Background Technology

[0002] Hot melt adhesive is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, and store. It is solvent-free, pollution-free, non-toxic, and has advantages such as simple production process, high added value, high bonding strength, and fast speed. Hot melt machines are mainly automated application equipment used to apply hot melt adhesive.

[0003] Existing hot melt machines mostly use rigid guide plates with fixed angles for feeding and guiding. However, different specifications of materials require the replacement of corresponding fixed guide plates. The replacement requires manual disassembly and adjustment, which takes a long time and leads to a reduction in production efficiency. Summary of the Invention

[0004] To improve the feeding efficiency of different materials, this application provides a feeding guide structure for a hot melt machine.

[0005] This application provides a feeding guide structure for a hot melt machine, which adopts the following technical solution:

[0006] A feeding guide structure for a hot melt machine includes a hot melt machine body, a mounting frame installed on one side of the hot melt machine body, a rotating roller rotatably connected between the two sides of the mounting frame, a pressure roller rotatably connected to the top of the mounting frame, movable grooves opened on the top surfaces of the two sides of the mounting frame, the movable grooves being arranged vertically along the mounting frame, the two ends of the pressure roller being located in the movable grooves close to it, the outer wall of the pressure groove abutting against the outer wall of the rotating roller, the feeding port of the hot melt machine body being aligned between the pressure roller and the rotating roller, a guide plate installed between the two sides of the mounting frame, the guide plate being located at the bottom of the rotating roller, the output end of the guide plate being aligned with the feeding port, the guide plate being inclined, and the inclined direction of the guide plate being from top to bottom from the discharge port to the feeding port.

[0007] By adopting the above technical solution, when the material is thin, the guide plate guides the material from the feed inlet into the hot melt machine body. When the material is thick, the rotating roller and the pressure roller guide the material, placing it between the pressure roller and the rotating roller. The material exerts an upward force on the pressure roller, causing the pressure roller to move upward along the moving groove. This allows the space between the pressure roller and the rotating roller to change according to the material thickness, thus adapting to materials of different thicknesses and uneven material thickness. This allows the pressure roller to better press the material, thereby better limiting the material and guiding it into the hot melt machine body. Compared to existing technologies where different specifications of materials require the replacement of corresponding guide plates, this application can save the time of manually disassembling and adjusting the guide plates, and can improve the feeding efficiency of different materials.

[0008] Preferably, each end of the pressure roller is provided with a movable block for installation. The two movable blocks are slidably connected to the top two sides of the mounting frame, and the two movable blocks are located in the movable grooves close to them.

[0009] By adopting the above technical solution, when the moving block moves up and down along the moving groove, it can drive the pressure roller to move up and down. Under the action of the moving block, the moving block can move up and down along the mounting frame more stably, reducing the deviation and swaying of the pressure roller when it moves up and down.

[0010] Preferably, each of the two movable blocks has a movable groove, and the two ends of the pressure roller are respectively movably inserted into the movable grooves that are close to it.

[0011] By adopting the above technical solution, the material applies an upward force to the pressure roller, causing the pressure roller to move upward along the movable groove. When the pressure roller is at the top of the movable groove, the moving block moves upward along the movable groove. Under the action of the movable groove, the upward movement distance of the pressure roller can be increased, thereby allowing thicker materials to pass between the pressure roller and the rotating roller, further improving the applicability of the guiding structure.

[0012] Preferably, limit plates are fixed at both ends of the top surface of the guide plate, with the long side of the limit plate parallel to the wide side of the guide plate, and a limiting space for placing materials is reserved between the bottom surface of the limit plate and the top surface of the guide plate.

[0013] By adopting the above technical solution, under the action of the limiting plate, when the material is placed on the top surface of the guide plate, both ends of the material are located in the limiting space close to it, thereby limiting the two ends of the material and reducing the deviation of the material when it moves along the guide plate.

[0014] Preferably, the guide plate and the limiting plate are made of conductive plastic plates.

[0015] By adopting the above technical solution, the guide plate and the limiting plate are made of conductive plastic plates. When the material rubs against the guide plate and the limiting plate, the static electricity between the material and the guide plate and the limiting plate can be reduced, thereby further reducing the deviation of the material during movement.

[0016] Preferably, the outer wall of the mounting frame is provided with a rotation drive component, which is installed on one side of the mounting frame. The end of the rotating roller near the rotation drive component extends out of the side wall of the mounting frame, and the part of the rotating roller extending out of the side wall of the mounting frame is assembled with the output end of the rotation drive component.

[0017] By adopting the above technical solution, when one end of the material is inserted between the pressure roller and the rotating roller, the rotation drive is activated. The motor rotates the drive to drive the rotating roller to rotate, and the rotating roller moves the material, thereby better guiding the material.

[0018] Preferably, the top surface of the guide plate has ventilation holes, and there are multiple ventilation holes, which are distributed in an orderly manner along the top surface of the guide plate.

[0019] By adopting the above technical solution, when the material is placed on the top surface of the guide plate, gas enters between the guide plate and the material through the ventilation hole, thereby forming an air layer between the material and the guide plate. This reduces friction and electrostatic adsorption between the material and the guide plate, and further reduces the possibility of the material shifting during movement.

[0020] Preferably, the guide plate has a flow cavity inside, the ventilation hole is connected to the flow cavity, and a blower is provided at the bottom of the guide plate. The output end of the blower is inserted into the bottom of the guide plate and is located in the flow cavity.

[0021] By adopting the above technical solution, the blowing component is activated, and the gas enters the flow cavity through the output end of the blowing component. Then, the gas is discharged from the ventilation hole and enters the space between the material and the guide plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the material is thin, it is guided from the feed inlet into the hot melt machine body by a guide plate. When the material is thick, it is guided by a rotating roller and a pressure roller, placing the material between the pressure roller and the rotating roller. The material exerts an upward force on the pressure roller, and the pressure roller moves upward along the moving groove. This allows the space between the pressure roller and the rotating roller to change according to the material thickness, thus adapting to materials of different thicknesses and uneven material thickness. This allows the pressure roller to better press the material, thereby better limiting the material and guiding it into the hot melt machine body. Compared with the prior art, where different specifications of materials require the replacement of corresponding guide plates, this application can save the time of manually disassembling and adjusting the guide plates, and can improve the feeding efficiency of different materials.

[0024] 2. When the material is placed on the top surface of the guide plate, gas enters between the guide plate and the material through the ventilation holes, thereby forming an air layer between the material and the guide plate. This reduces friction and electrostatic adsorption between the material and the guide plate, and further reduces the possibility of the material shifting during movement. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] This application discloses a feeding guide structure for a hot melt machine.

[0030] Reference Figure 1 and Figure 2A feeding guide structure for a hot melt machine includes a hot melt machine body 1. A feeding port 11 is provided on one side of the hot melt machine body 1, through which material 6 enters the hot melt machine body 1. Correspondingly, a discharge port is provided on the other side of the hot melt machine body 1. The feeding port 11 and the discharge port are distributed opposite to each other on both sides of the hot melt machine body 1. After the material 6 enters the hot melt machine body 1, the hot melt machine body 1 coats the surface of the material 6 with hot melt adhesive. Then, the material 6 is output from the discharge port of the hot melt machine body 1. A traction device pulls the output material 6, thereby pulling the material 6 from one end of the feeding port 11 to the other end of the discharge port.

[0031] A mounting frame 2 is installed on one side of the hot melt machine body 1. The mounting frame 2 is located at the end of the hot melt machine body 1 near the feed port 11. The long side of the mounting frame 2 is parallel to the wide side of the hot melt machine body 1. A rotating roller 31 is arranged between the two sides of the mounting frame 2. The two ends of the rotating roller 31 are rotatably connected to the side wall of the mounting frame 2 that is close to it. A rotating drive component is provided on the outer wall of the mounting frame 2. In this embodiment, the rotating drive component is a motor 32. The motor 32 is installed on one side of the mounting frame 2. The end of the rotating roller 31 near the motor 32 extends out of the side wall of the mounting frame 2. The part of the rotating roller 31 that extends out of the side wall of the mounting frame 2 is assembled with the output end of the motor 32. When the motor 32 is started, the motor 32 can drive the rotating roller 31 to rotate.

[0032] The top of the mounting frame 2 is provided with a pressure roller 41, and each end of the pressure roller 41 is provided with a movable block 42 for installation. Movable grooves 21 are opened on the top surfaces of both sides of the mounting frame 2. The movable grooves 21 are arranged vertically along the mounting frame 2. The two movable blocks 42 are slidably connected to the top sides of the mounting frame 2. The two movable blocks 42 are located in the movable grooves 21 that are close to them. Correspondingly, movable grooves 421 are opened in the two movable blocks 42. The two ends of the pressure roller 41 are movably inserted into the movable grooves 421 that are close to them. The outer wall of the pressure roller 41 abuts against the outer wall of the rotating roller 31. The feed port 11 is aligned between the pressure roller 41 and the rotating roller 31.

[0033] Reference Figure 1 and Figure 2When the material 6 is thick and difficult to bend, insert one end of the material 6 between the pressure roller 41 and the rotating roller 31, start the motor 32, the motor 32 drives the rotating roller 31 to rotate, the rotating roller 31 drives the material 6 to move, at the same time, the material 6 applies an upward force to the pressure roller 41, so that the pressure roller 41 moves upward along the movable groove 421. When the pressure roller 41 is at the top of the movable groove 421, the moving block 42 moves upward along the movable groove 21, so that the space between the pressure roller 41 and the rotating roller 31 can be changed according to the thickness of the material 6, thereby adapting to materials 6 of different thicknesses and to the situation where the thickness of the material 6 is uneven, so that the pressure roller 41 can better press the material 6, thereby better limiting the material 6 and guiding the material 6 into the hot melt machine body 1, reducing the positional deviation of the material 6 when entering the hot melt machine body 1, and thus allowing the hot melt machine body 1 to better apply glue to the material 6.

[0034] A guide plate 5 is installed between the two sides of the mounting frame 2. The guide plate 5 is located at the bottom of the rotating roller 31. The output end of the guide plate 5 is aligned with the feed port 11. The guide plate 5 is inclined. The inclination direction of the guide plate 5 is from top to bottom from the discharge port to the feed port 11. When the material 6 is thin, it is easy for the material 6 to be attracted to the outer wall due to static electricity when it rubs against the pressure roller 41 and the rotating roller 31, which makes it easy for the position of the material 6 to be offset. Therefore, the thinner material 6 is placed on the top surface of the guide plate 5. Then, the material 6 enters the hot melt machine body 1 from the feed port 11. The hot melt machine body 1 coats the material 6 with hot melt adhesive.

[0035] Limiting plates 51 are fixed at both ends of the top surface of the guide plate 5. The long side of the limiting plate 51 is parallel to the wide side of the guide plate 5. A limiting space for placing material 6 is reserved between the bottom surface of the limiting plate 51 and the top surface of the guide plate 5. When material 6 is placed on the top surface of the guide plate 5, both ends of material 6 are located in the limiting space close to it, thereby limiting the two ends of material 6 and reducing the possibility of material 6 deviating when moving along the guide plate 5.

[0036] Reference Figure 1 and Figure 2 In this embodiment, the guide plate 5 and the limiting plate 51 are conductive plastic plates. When the material 6 rubs against the guide plate 5 and the limiting plate 51, the static electricity between the material 6 and the guide plate 5 and the limiting plate 51 can be reduced, thereby further reducing the displacement of the material 6 during movement.

[0037] The guide plate 5 has a flow cavity inside, and a ventilation hole 52 is provided on the top surface of the guide plate 5. The ventilation hole 52 communicates with the flow cavity. There are multiple ventilation holes 52, which are arranged in an orderly manner along the top surface of the guide plate 5. A blower is provided at the bottom of the guide plate 5. In this embodiment, the blower is a blower 53. The output end of the blower 53 is inserted into the bottom of the guide plate 5. The output end of the blower 53 is located in the flow cavity. When the blower 53 is started, gas enters the flow cavity through the output end of the blower 53. Then, the gas is discharged from the ventilation hole 52, thereby forming an air layer between the material 6 and the guide plate 5. This reduces the friction and electrostatic adsorption between the material 6 and the guide plate 5, thereby further reducing the displacement of the material 6 during movement.

[0038] When material 6 is thin, it is guided by guide plate 5 from feed port 11 into the hot melt machine body 1. When material 6 is thick, it is guided by rotating roller 31 and pressure roller 41 so that material 6 enters the hot melt machine body 1 from feed port 11. Furthermore, the rotation roller 31 and pressure roller 41 can be adjusted according to the thickness of material 6. Compared with the prior art, where different specifications of material 6 require the replacement of corresponding guide plates, this application can save the time of manually disassembling and adjusting the guide plates and improve the feeding efficiency of different materials 6.

[0039] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
