Description

Technical Field

[0001] This utility model relates to a hot melt adhesive heat transfer device, belonging to the field of hot melt adhesive technology. Background Technology

[0002] Hot melt adhesive is a type of malleable adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. It is highly favored due to its solid nature, ease of packaging, transportation, and storage; solvent-free, pollution-free, and non-toxic properties; simple production process; high added value; and advantages such as strong and fast bonding.

[0003] Existing hot melt adhesive heat transfer equipment mostly involves preheating the hot melt adhesive to a liquid state before placing it on the production line for product coating. However, as time goes on, the temperature of the hot melt adhesive itself will gradually decrease, making it prone to becoming thick and even solidifying before coating, which affects production. The surface of the coating equipment is also prone to solidified hot melt adhesive, which is difficult to clean.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this invention is to solve the problem that as the temperature of hot melt adhesive gradually decreases over time, it tends to thicken and may even solidify before being applied, affecting production and causing solidified hot melt adhesive to easily form on the surface of the coating equipment, making it difficult to clean. Therefore, this invention provides a hot melt adhesive heat transfer device.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A hot melt adhesive heat transfer device includes a base and a transfer mechanism and a mating mechanism mounted on the upper surface of the base. The transfer mechanism and the mating mechanism are staggered. The transfer mechanism includes a heat insulation box, an adhesive roller rotatably connected to the inner wall of the heat insulation box, a connecting column fixedly connected to one end of the adhesive roller, an insulating frame fixedly connected to the upper surface of the base, the inner wall of the insulating frame rotatably connected to the connecting column, a grounding groove formed on the surface of the connecting column, a current-carrying ring provided on the inner wall of the grounding groove, a connecting pipe fixedly connected to the inner wall of the insulating frame, a spring provided on the inner wall of the connecting pipe, a sliding plate slidably connected to the inner wall of the connecting pipe, a grounding socket fixedly connected to the upper surface of the sliding plate, and a grounding ball provided on the inner wall of the grounding socket.

[0008] Preferably, a heating tube is fixedly connected to the inner wall of the adhesive roller, and the heating tube is electrically connected to the energized ring.

[0009] Preferably, a partition cover is fixedly connected to the inner wall of the glue-applying roller, and a wear-resistant layer is provided on the surface of the glue-applying roller.

[0010] Preferably, the front of the heat insulation box is provided with an outer shell, and a drive motor is fixedly connected to the surface of the outer shell.

[0011] Preferably, a rotating rod is rotatably connected to the inner wall of the heat insulation box, and the surface of the rotating rod is provided with stirring blades.

[0012] Preferably, one end of the gluing roller and the rotating rod are both fixedly connected to pulleys through the heat insulation box, and the pulleys are connected to each other by belt drive.

[0013] Preferably, a partition is fixedly connected to the inner wall of the heat insulation box, and an electric heating wire is fixedly connected to the inner wall of the heat insulation box and inside the partition.

[0014] Preferably, the mating mechanism includes a collection basin, and a mounting bracket is fixedly connected to the upper surface of the collection basin.

[0015] Preferably, a pressure roller is rotatably connected to the inner wall of the mounting frame, and an electric push rod is fixedly connected to the inner wall of the mounting frame.

[0016] Preferably, a scraper is fixedly connected to the output end of the electric push rod.

[0017] The beneficial technical effects of this utility model are as follows: Under the elastic force of the spring, the sliding plate applies an upward thrust to the contact seat, causing the contact ball and the energizing ring to fit tightly together. This allows the current to continuously pass through the contact seat, the contact ball, and the energizing ring, supplying power to the heating tube, thereby continuously heating the glue roller. This prevents the hot melt adhesive on the glue roller from solidifying. When cleaning the hot melt adhesive on the glue roller, the heating tube heats the glue roller, making it easier to clean as the hot melt adhesive on the surface of the glue roller does not solidify. Heating is achieved through the heating wire and heat conduction through the partition, which heats the hot melt adhesive inside the heat insulation box, preventing the hot melt adhesive from solidifying. The rotating rod drives the stirring blade to rotate, causing the hot melt adhesive inside the heat insulation box to flow, facilitating the adhesion of the hot melt adhesive to the glue roller.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-6As shown, this embodiment provides a hot melt adhesive heat transfer device, including a base 1 and a transfer mechanism 2 and a mating mechanism 3 mounted on the upper surface of the base 1. The transfer mechanism 2 and the mating mechanism 3 are staggered. The transfer mechanism 2 includes a heat insulation box 201, which reduces the cooling rate of the hot melt adhesive inside. An adhesive application roller 202 is rotatably connected to the inner wall of the heat insulation box 201. A connecting column 203 is fixedly connected to one end of the adhesive application roller 202. An insulating frame is fixedly connected to the upper surface of the base 1. 204. The inner wall of the insulating frame 204 is rotatably connected to the connecting column 203. A current-connecting groove 205 is formed on the surface of the connecting column 203. A current-conducting ring 206 is provided on the inner wall of the current-connecting groove 205. A connecting pipe 207 is fixedly connected to the inner wall of the insulating frame 204. A spring 211 is provided on the inner wall of the connecting pipe 207. A sliding plate 208 is slidably connected to the inner wall of the connecting pipe 207. A current-connecting base 209 is fixedly connected to the upper surface of the sliding plate 208. The inner wall of the current-connecting base 209 is provided with… A heating tube 216 is fixedly connected to the inner wall of the glue-applying roller 202, and the heating tube 216 is electrically connected to the energized ring 206. Hot melt adhesive is placed in the heat-insulating box 201, and the energized base 209 is connected to an external circuit. When the glue-applying roller 202 rotates, the energized ring 206 rotates, and the spring 211 is compressed. Therefore, the spring 211 generates elastic force. Under the action of the elastic force of the spring 211, the sliding plate 208 applies an upward push to the energized base 209. The force ensures that the contact ball 210 and the energizing ring 206 are tightly fitted, allowing current to continuously pass through the contact base 209, contact ball 210, and energizing ring 206 to supply power to the heating tube 216, thereby continuously heating the glue roller 202. This prevents the hot melt adhesive on the glue roller 202 from solidifying. When cleaning the hot melt adhesive on the glue roller 202, the heating tube 216 heats the glue roller 202, making it easier to clean as the hot melt adhesive on the surface of the glue roller 202 is less likely to solidify.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a partition cover 215 is fixedly connected to the inner wall of the top glue roller 202, and a wear-resistant layer 217 is provided on the surface of the top glue roller 202. An outer shell 212 is provided on the front of the heat insulation box 201, which covers the pulley 214 to prevent it from injuring workers. A drive motor 213 is fixedly connected to the surface of the outer shell 212. A rotating rod 218 is rotatably connected to the inner wall of the heat insulation box 201, and a stirring blade 219 is provided on the surface of the rotating rod 218. The top glue roller 202 and the rotating rod 218... One end of each rod 218 passes through the heat insulation box 201 and is fixedly connected to a pulley 214. The pulleys 214 are connected by a belt drive. The drive motor 213 drives the glue roller 202 to rotate. The glue roller 202 drives the rotating rod 218 to rotate through the cooperation of the pulleys 214 and the belt. The rotating rod 218 rotates to coat the material to be coated. The rotating rod 218 drives the stirring blade 219 to rotate, which drives the hot melt adhesive inside the heat insulation box 201 to flow, so that the hot melt adhesive can adhere to the glue roller 202.

[0028] In this embodiment, as Figure 4 As shown, a partition 221 is fixedly connected to the inner wall of the heat insulation box 201. An electric heating wire 220 is fixedly connected to the inner wall of the heat insulation box 201 and inside the partition 221. The partition 221 separates the hot melt adhesive inside the heat insulation box 201, making it difficult for hot melt adhesive to adhere to the electric heating wire 220. Heating is carried out through the electric heating wire 220. The material of the partition 221 is a heat-conducting material. The partition 221 conducts heat to heat the hot melt adhesive inside the heat insulation box 201 and prevents the hot melt adhesive from solidifying.

[0029] In this embodiment, as Figure 1 and Figure 6 As shown, the cooperating mechanism 3 includes a collection basin 301, a mounting frame 302 is fixedly connected to the upper surface of the collection basin 301, a pressure roller 303 is rotatably connected to the inner wall of the mounting frame 302, an electric push rod 304 is fixedly connected to the inner wall of the mounting frame 302, and a scraper 305 is fixedly connected to the output end of the electric push rod 304. First, the electric push rod 304 is retracted to draw the material to be coated out between the scraper 305 and the pressure roller 303. Then, the electric push rod 304 is extended so that the scraper 305 fits against the material to be coated and scrapes off the excess hot melt adhesive on the material to be coated.

[0030] In this embodiment, as Figures 1-6 As shown in the figure, the working principle of the hot melt adhesive heat transfer device provided in this embodiment is as follows:

[0031] Step 1: Place the hot melt adhesive into the heat insulation box 201;

[0032] Step 2: The lower surface of the material to be coated is attached to the glue roller 202 and pulled out, and then the material to be coated is pulled out between the scraper 305 and the pressure roller 303;

[0033] Step 3: Move the material to be coated. Drive motor 213 drives the coating roller 202 to rotate. The coating roller 202 drives the rotating rod 218 to rotate through the cooperation of pulley 214 and belt. The coating roller 202 rotates to coat the material to be coated.

[0034] Step 4: The rotating rod 218 drives the stirring blade 219 to rotate, which in turn causes the hot melt adhesive inside the heat insulation box 201 to flow, making it easier for the hot melt adhesive to adhere to the glue roller 202.

[0035] Step 5: Extend the electric push rod 304 so that the scraper 305 fits against the material to be coated and scrapes off the excess hot melt adhesive on the material to be coated.

[0036] Step six: When the glue roller 202 rotates, the energized ring 206 rotates, and the spring 211 is compressed. Therefore, the spring 211 generates elastic force. Under the action of the elastic force of the spring 211, the sliding plate 208 applies an upward pushing force to the electrode base 209, so that the electrode ball 210 and the energized ring 206 are tightly attached. This allows the current to continuously pass through the electrode base 209, the electrode ball 210 and the energized ring 206, supplying power to the heating tube 216, thereby continuously heating the glue roller 202 and making the hot melt adhesive on the glue roller 202 less likely to solidify.

[0037] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
