Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic particle processing, in particular to a hot-melt device for plastic particle processing. Background Art
[0002] Plastic pellet processing, also known as plastic granulation, is an important process in plastic processing. This process involves mixing, melting, and extruding polymer resins (such as plastics) with various additives and auxiliaries in a certain proportion, and finally cutting them into granular plastics. The process of plastic pellet processing includes multiple steps, such as screening, cleaning, and drying of raw materials, as well as mixing with other ingredients such as plasticizers and pigments. In addition, the use of granular plastic raw materials can also help reduce bubbles and pollution in production, improve production efficiency and product quality, and the processing of plastic pellets also involves the processing of recycled materials. These pellets can be further used in molding processes such as injection molding, extrusion, and blow molding to manufacture various plastic products. In the process of plastic pellet processing, it is sometimes necessary to hot-melt the plastic pellets, which involves a plastic pellet processing hot-melt device.
[0003] However, when the existing hot melt device is processing plastic particles, it is necessary to manually place the plastic particles into the hot melt machine, which is very inconvenient. In addition, the temperature inside the hot melt machine can easily burn the operator's hands, which poses a certain safety hazard. After the particles are hot-melted, the hot-melted colloid needs to be discharged. Most plastic particle hot melt devices cannot control the flow rate of the discharged colloid, which results in a large area of the colloid being exposed to the outside air, resulting in the consequence of too rapid cooling.

When the plastic particles need to be processed, the operator opens the cover plate 36 by the handle 37, and then pours the plastic particles into the silo 34. The plastic particles are screened by the sieve plate 39, and the uneven plastic particles are retained on the sieve plate 39. The plastic particles sink to the conveying port 381 through the silo 34. The material level position is observed through the observation port 35, and the first motor 32 is started. The output end of the first motor 32 drives the conveying port 381 to rotate, and the rotating conveying roller 382 pushes the descending plastic particles upward through the spiral blades, and pushes the plastic particles to be transmitted to the other end of the feeding tube 38 through the feeding tube 38. The fixed sleeve 321 and the fixed seat 33 on the outer surface of the feeding tube 38 play a role in stably supporting the feeding tube 38, and finally flows into the hot glue machine 2 through the other end of the feeding tube 38, thereby achieving the purpose of convenient feeding.
[0018] The automatic opening and closing device 4 includes a valve body 41, a fixing member 43 is fixedly connected to the top of the valve body 41, a rotating shaft 44 is inserted and rotatably connected to the outer surface of the fixing member 43, one end of the rotating shaft 44 passes through the valve body 41 and is fixedly connected to the valve core 42, a worm wheel groove 45 is provided on the outer surface of the rotating shaft 44, a worm 46 is meshedly connected to the outer surface of the worm wheel groove 45, a valve housing 40 is sleeved on the outer surface of the rotating shaft 44, a second motor 47 is fixedly installed on the inner wall of one end of the valve housing 40, the output end of the second motor 47 is fixedly connected to one end of the worm 46, one end of the worm 46 is rotatably connected to the inner wall of the other side of the valve housing 40, a spare wheel disc 48 is fixedly connected to the top of the rotating shaft 44, when it is necessary to discharge the hot-melt plastic, the operator opens the feed port 21 by sliding the sliding plate 22, so that The plastic particles fall into the hot melt chamber in the hot glue machine 2. The plastic particles in the hot melt chamber are heated and melted by the heating pump to form liquid, and finally flow out from one end of the hot glue machine 2. The automatic opening and closing device 4 at one end of the hot glue machine 2 starts the second motor 47. The output end of the second motor 47 drives the worm 46 to rotate. The rotating worm 46 drives the rotating shaft 44 to rotate through the worm gear groove 45 on the outer surface of the rotating shaft 44, so that the valve core 42 fixedly connected to the rotating shaft 44 is horizontally rotated in the valve body 41 with the rotating shaft 44 as the axis. When the valve core 42 rotates to the maximum opening, the hot-melted plastic can flow out at the maximum flow rate. The spare wheel disc 48 at the top of the rotating shaft 44 plays a role in that the spare wheel disc 48 can be manually rotated and reset when the second motor 47 fails or the valve core 42 is stuck.
[0019] A sieve plate 39 is fixedly clamped on the inner surface of the silo 34, and a plurality of filter grooves distributed in a rectangular array are provided on the outer surface of the sieve plate 39. An observation port 35 is provided at one end of the silo 34, and an observation glass is fixedly connected between the inner walls of the observation port 35. The feeding pipe 38 and the first motor 32 are both inclined, and the feeding pipe 38 is "L"-shaped. The sieve plate 39 mainly plays a role in filtering irregular or large-sized plastic particles to ensure the melting effect of the hot glue machine 2. The operator can judge the material level in the silo 34 through the observation glass of the observation port 35 in order to replenish the material in time. The inclined first motor 32 and the feeding pipe 38 are for facilitating a more stable flow of the rising plastic particles to avoid clogging of the material pipe due to excessive flow rate of the material in the material pipe. The "L"-shaped feeding pipe 38 is for facilitating the plastic particles to flow from the other end of the feeding pipe 38 into the feed port 21.
[0020] The outer surface of the conveying roller 382 is fixedly connected with a spiral blade, and the outer surface of the spiral blade is slidingly fitted with the inner surface of the feeding tube 38. The spiral blade on the surface of the conveying roller 382 is used to continuously push the plastic particles to the output end through rotation. During the conveying process, the material is subjected to the friction between the spiral blade and the outer shell, thereby generating axial movement.
[0021] The diameter of the valve core 42 is the same as the inner diameter of the valve body 41 , and the outer surface of the valve core 42 is slidably fitted with the inner surface of the valve body 41 . The valve core 42 is rotated to adjust the opening and closing degree of the valve core 42 , so that the flowing colloid flows out through the valve body 41 .
[0022] Working principle: When it is necessary to process the plastic particles, the operator opens the cover plate 36 by the handle 37, and then pours the plastic particles into the silo 34. The plastic particles are screened by the sieve plate 39, and the plastic particles with uneven particles are retained on the sieve plate 39. The plastic particles sink to the conveying port 381 through the silo 34, and the material level position is observed through the observation port 35. The first motor 32 is started, and the output end of the first motor 32 drives the conveying port 381 to rotate. The rotating conveying roller 382 pushes the descending plastic particles upward continuously through the spiral blades, and pushes the plastic particles to be transmitted to the other end of the feeding tube 38 through the feeding tube 38. The fixed sleeve 321 and the fixed seat 33 on the outer surface of the feeding tube 38 play a role in stably supporting the feeding tube 38, and finally flow into the hot glue machine 2 through the other end of the feeding tube 38, thereby achieving the purpose of convenient feeding;
[0023] When it is necessary to discharge the hot-melt plastic, the operator opens the feed port 21 by sliding the sliding plate 22, so that the plastic particles fall into the hot-melt bin in the hot-glue machine 2. The plastic particles in the hot-melt bin are heated and melted by the heating pump to form liquid, and finally flow out from one end of the hot-glue machine 2. The automatic opening and closing device 4 at one end of the hot-glue machine 2 starts the second motor 47, and the output end of the second motor 47 drives the worm 46 to rotate. The rotating worm 46 drives the rotating shaft 44 to rotate through the worm gear groove 45 on the outer surface of the rotating shaft 44, so that the valve core 42 fixedly connected to the rotating shaft 44 is horizontally rotated in the valve body 41 with the rotating shaft 44 as the axis. When the valve core 42 rotates to the maximum opening, the hot-melt plastic can flow out at the maximum flow rate. The spare wheel disc 48 at the top of the rotating shaft 44 plays a role in that the spare wheel disc 48 can be manually rotated and reset when the second motor 47 fails or the valve core 42 is stuck.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
