Description

Technical Field

[0001] The utility model relates to the field of extrusion, and more specifically, to a solid glue production extrusion device. Background Art

[0002] A solid glue extrusion device is a device used to extrude or shape solid glue (such as solid glue sticks, crayons, soaps, etc.) from its container. The solid glue extrusion device generally includes a feeding system, a heating system, an extrusion system and a cooling system. The raw materials enter the device through the feeding system, and the raw materials are softened or even melted by the heating system. The softened raw materials are then extruded through the extrusion system. During the extrusion process, the raw materials are cooled by the cooling system to solidify them into the desired shape. Since most products are a mixture of multiple raw materials and additives, before being extruded through the solid glue extrusion device, most of the raw materials need to be mixed in advance through a mixing device, and then transported to the extrusion device to wait for processing. During this process, most of the raw materials have been cooled, which increases the burden on the heating system in the extrusion device and reduces production efficiency to a certain extent. In addition, during the cooling process of the raw materials by the cooling system, the heat energy on the raw materials is not recycled, which also results in a certain amount of energy loss.

[0003] Based on the above, the purpose of the present invention is to provide a solid glue production extrusion device to solve the above problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a solid glue production extrusion device. The present invention sets a feed hopper and a cooling pipe, and then sets a heating pipe and a cooling pipe in the feed hopper and the cooling pipe respectively, and then connects the heating pipe and the cooling pipe to each other to form a loop. The coolant circulates between the cooling pipe and the heating pipe through the drive of a water pump. With this arrangement, the cooling pipe will absorb the heat energy on the extruded raw materials, and then cool the raw materials, and then supply these raw materials to the raw materials in the feed hopper to achieve a preheating effect, thereby realizing heat energy recovery and improving production efficiency.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a solid glue production extrusion device, including a feeding system, a heating system, an extrusion system and a cooling system, the heating system including a heating barrel, the discharge port of the heating barrel is connected to the extrusion system, a heater is provided in the heating barrel, the feeding system includes a feed hopper, a feed pipe is provided between the feed hopper and the heating barrel, a valve is provided on the feed pipe, a spirally arranged heating pipe is provided on the feed hopper, the cooling system includes an extrusion pipe connected to the discharge port of the extrusion system, a cooling jacket is provided on the extrusion pipe, a spirally arranged cooling pipe is provided on the cooling jacket, both ends of the cooling pipe are respectively connected to the two ends of the heating pipe, and a water pump is provided on the cooling pipe.

[0006] By adopting the above technical solution, when an extruder is used for solid glue extrusion, the heater and the water pump are turned on, the heater will melt the raw materials, the melted raw materials will enter the extrusion system and be extruded, and the extruded raw materials will pass through the extrusion tube. In this process, the coolant flowing in the cooling tube will take away the heat energy on the raw materials, thereby cooling the raw materials. Subsequently, the coolant carrying heat energy will enter the heating tube, and the raw materials to be processed in the feed hopper will be preheated through the heating tube, thereby realizing the recovery of the heat energy carried by the raw materials in the cooling system. The preheated raw materials can also reduce the heating time in the heating barrel, thereby improving production efficiency.

[0027] Furthermore, the water inlet end of the cooling pipe 8 is arranged in a spiral or circuitous shape.

[0028] Working principle: When using the extrusion equipment to extrude solid glue, turn on the motor 10, heater 2 and water pump 9, the heater 2 will melt the raw materials, the heating plate 13 and the filter 14 will separate the inner cavity of the heating barrel 1 into a heating cavity and a storage cavity, the melted raw materials will pass through the filter 14 and flow into the storage cavity, the filter 14 will filter the impurities in the raw materials, the motor 10 will drive the stirring rod 12 and the scraper 15 to rotate through the rotating shaft 11, the stirring rod 12 will stir the raw materials in the heating cavity and the raw material solution in the storage cavity respectively, so that the raw materials are mixed more evenly and the bubbles in the raw material solution are reduced.
