Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive film coating production, in particular to a hot melt adhesive film coating production line. Background Art

[0002] Hot melt adhesive film coating production is a process of applying hot melt adhesive on a substrate and cooling it to form a film. This process usually includes several steps such as pretreatment, coating, thickness determination and film formation. In the pretreatment stage, the substrate to be coated needs to be surface treated to ensure the quality of the coating. In the coating stage, the hot melt adhesive needs to be evenly coated on the substrate. Usually, the hot melt adhesive needs to be heated to a liquid state in advance before coating.

[0003] In the existing hot melt adhesive film coating production process, the coating substrate is usually directly driven into the coating machine for coating, and then dried and solidified. Before the coating work, the surface of the coating substrate may absorb a small amount of dust and hair, and the device is not convenient to complete the cleaning work before the coating substrate is coated, which will have a certain impact on the quality of the coating and lead to the problem of low practicality. For this reason, we provide a production line for producing hot melt adhesive film coating to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a coating production line for producing hot melt adhesive films.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a production line for producing hot-melt adhesive film coating, comprising a base plate, the upper surface of the base plate being fixedly connected to a fixing frame, a cleaning mechanism being arranged above the base plate, the cleaning mechanism comprising two limit frames, the bottom surface of each limit frame being fixedly connected to the upper surface of the base plate, the inner walls of the two limit frames being slidably connected to the limit plate together, the inner walls of the two limit frames being slidably connected to two support columns together, the outer surface of each support column being rotatably connected to a dust sticking cylinder, the outer surface of each support column being threadedly connected to two limit rings, the side surfaces of each group of limit rings being close to each other being in contact with the outer surface of the dust sticking cylinder, the inner wall of each limit frame being threadedly connected to two threaded pins, the outer surface of each threaded pin being threadedly connected to the inner wall of the limit plate, the inner wall of the limit plate being fixedly connected to two extrusion rings, the outer surface of each extrusion ring being slidably connected to the inner wall of the limit frame, and the inner wall of each extrusion ring being in contact with the outer surface of the support column.

[0006] Furthermore, four supporting legs are fixedly connected to the bottom surface of the bottom plate, and the bottom surface of each supporting leg is fixedly connected to a base.

[0007] Furthermore, two connecting frames are fixedly connected to the front side of the bottom plate, and the inner wall of each connecting frame is slidably connected to a fixing pin.

[0008] Furthermore, a nut is threadedly connected to the bottom end of each fixing pin, and an upper surface of each nut is in contact with the bottom surface of the connecting frame.

[0009] Furthermore, a fixing column is slidably connected to the inner wall of the fixing frame, and a rotating cylinder is rotatably connected to the outer surface of the fixing column.

[0010] Furthermore, two support blocks are fixedly connected to the upper surface of the bottom plate, and the inner walls of the two support blocks are rotatably connected to two rotation shafts.

[0011] Furthermore, a coating machine is fixedly connected to the upper surface of the base plate, and a supporting frame is fixedly connected to the upper surface of the base plate.

[0012] Furthermore, a cooling machine is fixedly connected to the front of the coating machine, and the bottom surface of the cooling machine is fixedly connected to the upper surface of the bottom plate.

[0013] Compared with the existing technology, the production line for producing hot melt adhesive film coating has the following beneficial effects:

[0014] The utility model provides a limit frame, a support column, a limit ring and a dust sticking cylinder, so that under the action of the dust sticking cylinder, when the production line drives the coated substrate to move for production, the coated substrate can pass through the gap between the two support columns and the dust sticking cylinder. In the process of the coated substrate passing through, the dust sticking cylinder on the surface of the support column can be driven to rotate, and the rotation of the dust sticking cylinder can contact the surface of the coated substrate. At the same time, since the coated substrate itself is not sticky, the dust sticking cylinder can quickly stick to the dust and hair on the surface of the coated substrate, thereby improving the cleanliness of the surface of the coated substrate and improving the quality of the coating film of the coated substrate.

[0015] The utility model is provided with a threaded pin, a limit plate and an extrusion ring, so that under the action of the limit plate, the limit plate can drive the extrusion ring to extrude and limit the support column, and further reinforce it through the threaded pin, thereby ensuring a stable cleaning state, and also facilitating the disassembly and replacement of the dust sticking cylinder.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] This embodiment provides a production line for producing hot melt adhesive film coating. The device is used to quickly clean dust and hair on the surface of the coating substrate before the coating substrate is coated.

By arranging the supporting legs 308 and the base 309, a good supporting effect can be provided for the device, so that it can be used stably.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 3 includes two limit frames 301, the bottom surface of each limit frame 301 is fixedly connected to the upper surface of the bottom plate 1, and the front of the bottom plate 1 is fixedly connected to two connecting frames 310. The inner wall of each connecting frame 310 is slidably connected to a fixed pin 311. By setting the connecting frame 310 and the fixed pin 311, the rear winding device can be easily connected to the bottom plate 1, thereby facilitating the winding work of the coating.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The inner walls of the two limit frames 301 are slidably connected to the limit plate 302, and the inner walls of the two limit frames 301 are slidably connected to the two support columns 303. The bottom end of each fixing pin 311 is threadedly connected to a nut 319, and the upper surface of each nut 319 is in contact with the bottom surface of the connecting frame 310. By setting the nut 319, the firmness of the fixing pin 311 can be further increased to avoid separation during use.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer surface of each support column 303 is rotatably connected to a dust sticking cylinder 304, and the outer surface of each support column 303 is threadedly connected to two limit rings 305. The inner wall of the fixed frame 2 is slidably connected to a fixed column 315, and the outer surface of the fixed column 315 is rotatably connected to a rotating cylinder 316. By setting the fixed column 315 and the rotating cylinder 316, the coated substrate can be conveniently placed for production work. At the same time, the two limit plates on the fixed column 315 can be removed to replace the rotating cylinder 316.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The side surfaces of each set of limiting rings 305 that are close to each other are in contact with the outer surface of the dust sticking cylinder 304. The inner wall of each limiting frame 301 is threadedly connected to two threaded pins 306. The upper surface of the bottom plate 1 is fixedly connected to two support blocks 312. The inner walls of the two support blocks 312 are rotatably connected to two rotating shafts 313. By setting the support blocks 312 and the rotating shafts 313, it is convenient to play a certain limiting role when the coated substrate is produced and processed.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer surface of each threaded pin 306 is threadedly connected to the inner wall of the limit plate 302, and the inner wall of the limit plate 302 is fixedly connected with two extrusion rings 307. The upper surface of the base plate 1 is fixedly connected with a coating machine 317, and the upper surface of the base plate 1 is fixedly connected with a support frame 314. By setting the coating machine 317, the key equipment of the hot melt adhesive film coating process can be realized. These machines can handle various high-viscosity hot melt adhesives or thermoplastic materials, and meet higher precision coating by replacing the melt adhesive pump and the coating head. By setting the support frame 314, the coating can be further supported to avoid the situation of pulling down during coating.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The outer surface of each extrusion ring 307 is slidably connected to the inner wall of the limit frame 301, and the inner wall of each extrusion ring 307 is in contact with the outer surface of the support column 303. The front of the coating machine 317 is fixedly connected to a cooler 318, and the bottom surface of the cooler 318 is fixedly connected to the upper surface of the base plate 1. By setting the cooler 318, the cooler 318 can quickly cool down and shape the coating substrate after the coating is completed.

[0030] Working principle: When in use, the staff first transports the device to a suitable location for use, then turns on the power of the coating machine 317 and the cooling machine 318 so that they can be in a stable power-on state, then the staff removes the fixing pin 311 on the connecting frame 310, and connects the winding device to the bottom plate 1 through the fixing pin 311 and the nut 319, and then passes the coated substrate through the equipment on the production line and fixes it on the winding device, and then drives the coated substrate through the winding device for production and processing. When the production line drives the coated substrate to move production, the coated substrate can pass through the gap between the two support columns 303 and the dust sticking cylinder 304. During the process of the coated substrate passing through, it can drive the dust sticking on the surface of the support column 303 The cylinder 304 rotates, and the sticky cylinder 304 can be in contact with the surface of the coating substrate. At the same time, since the coating substrate itself is not sticky, the sticky cylinder 304 can quickly stick to the dust and hair on the surface of the coating substrate. Then the coating substrate enters the coating machine 317. The coating machine 317 can evenly apply hot melt adhesive on the coating substrate, and then move to the cooling machine 318 for cooling and shaping, thereby completing the coating production. When there is a lot of dust stuck on the surface of the sticky cylinder 304, the staff will remove the four threaded pins 306, and at the same time pull out the limit plate 302 and the extrusion ring 307, so that the sticky cylinder 304 can be taken out for replacement, and the sticky cylinder 304 can be firmly fixed again in the opposite way.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
