Technical Field

[0001] The utility model relates to the technical field of epoxy resin preparation, in particular to a heating and melting device for preparing modified epoxy resin. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a class of polymers containing two or more epoxy groups in the molecule. In order to obtain modified epoxy resin of better quality, it is necessary to go through multiple production experiments, in which the equipment and machines used include heating and melting devices.

[0003] When the existing hot melting device is working, the raw materials are generally first introduced into the melting tank, and then the heating mechanism and the stirring mechanism are started. The heating mechanism heats the raw materials for hot melting, and the stirring mechanism stirs the raw materials. However, due to the large amount of raw materials, the stirring speed of the stirring mechanism is also hindered, and there are also dead corners for stirring, which makes the melting efficiency low and affects the preparation efficiency.

[0008] Furthermore, a control panel is installed on the other side of the top of the mounting frame, and the control panel is electrically connected to the heating plate and the motor respectively.

[0009] By adopting the above technical solution, the staff can control the heating plate and the motor through the control panel.

[0010] Furthermore, the lower part of the interior of the storage bin is inclined toward the lower material opening.

[0011] By adopting the above technical solution, the inclined setting plays a diversion role, allowing the raw materials to slide down along the slope.

[0012] Furthermore, a slide rail is provided at the lower part of the interior of the mounting frame, a slide groove is provided at the bottom of the hot melt groove, and the slide groove is slidably matched with the slide rail.

[0013] By adopting the above technical solution, with the cooperation of the slide rail and the slide groove, the left and right movement of the hot melt groove is made more stable.

[0014] Furthermore, a discharge port is provided on the outer surface of the hot melt tank.

[0015] By adopting the above technical solution, the hot-melted raw materials can be quickly discharged from the discharge port.

[0020] Furthermore, one end of the spring is fixed to the inner wall of the mounting frame, and the spring is made of manganese steel.

[0021] By adopting the above technical solution, the spring can push the baffle plate to reset, and the manganese steel material makes the spring have a longer service life.

[0022] In summary, the utility model mainly has the following beneficial effects: the utility model is provided with a storage bin, a feeding port, a spring, a baffle plate, a reciprocating screw and a threaded block. When hot melting is performed, the motor rotates to rotate the drive shaft, thereby causing the second active bevel gear to drive the second driven bevel gear to rotate, thereby causing the reciprocating screw to rotate. The rotation of the reciprocating screw causes the threaded block to drive the hot melting groove to move left and right. During the movement, the storage bin will squeeze the baffle plate, thereby causing the spring to contract. When the baffle plate is squeezed and moved, the feeding port is opened, and the raw material falls from the feeding port. When the hot melting groove moves to the left, the spring pushes the baffle plate to move. The material plate is reset, and then the feed port is sealed, so as to achieve the purpose of intermittent feeding, avoiding too much feeding at one time to affect the heating and melting efficiency. At the same time, since the hot melt tank moves back and forth left and right, the stirring blade can evenly stir the raw materials, avoiding dead corners of stirring, and making the raw materials heated more evenly. At the same time, the rotation of the first active bevel gear can rotate the first driven bevel gear, so that the rotating shaft drives the crushing knife to rotate, and the crushing knife can further crush the raw materials. The crushed raw materials can be heated and melted faster, further improving the melting efficiency of the device and improving the production effect. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the first active bevel tooth 10 can cause the first driven bevel tooth 11 to rotate, and the rotation of the second active bevel tooth 12 can cause the second driven bevel tooth 13 to rotate. A discharge port 7 is provided at the bottom of the storage bin 2, and a baffle plate 9 is provided inside the discharge port 7. A spring 8 is provided on one side of the baffle plate 9. Heating plates 17 are installed on both sides of the hot melt groove 22. The heating plate 17 can heat the raw material and then melt the raw material. A discharge port 20 is provided on the outer surface of the hot melt groove 22, and the melted raw material can be quickly discharged from the discharge port 20.

[0031] See also Figure 1-Figure 2 In the above embodiment, a control panel 5 is installed on the other side of the top of the mounting frame 1, and the control panel 5 is electrically connected to the heating plate 17 and the motor 3 respectively. The staff can control the heating plate 17 and the motor 3 through the control panel 5.

[0032] See also Figure 2 In the above embodiment, the lower part of the interior of the storage bin 2 is inclined toward the lower material port 7, and the inclined setting plays a guiding role, so that the raw materials can slide down along the slope.

[0033] See also Figure 2 In the above embodiment, a plurality of stirring blades 23 are provided, and the plurality of stirring blades 23 are arranged equidistantly from top to bottom. The plurality of stirring blades 23 can stir the raw materials evenly, so that the raw materials are heated more evenly.

[0034] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, one end of the spring 8 is fixed to the inner wall of the mounting frame 1, and the spring 8 is made of manganese steel. The spring 8 can push the baffle plate 9 to reset, and the manganese steel material makes the spring 8 have a longer service life.

[0035] Embodiment 2: In order to make the left and right movement of the hot melt tank more stable, the embodiment 2 is improved on the basis of the embodiment 1. Figure 1-Figure 2 A slide rail 15 is provided at the lower part of the mounting frame 1, and a slide groove 16 is provided at the bottom of the hot melt groove 22, and the slide groove 16 is slidably matched with the slide rail 15. With the cooperation of the slide rail 15 and the slide groove 16, the hot melt groove 22 moves left and right more stably.

[0036] Embodiment 3: In order to make the raw material melt faster, embodiment 3 is improved on the basis of embodiment 1. Figure 2-Figure 3 A rotating shaft 14 is provided inside the storage bin 2, and a crushing knife 19 is provided on the outer surface of the rotating shaft 14.

[0037] The implementation principle of the utility model is as follows: when hot melting is performed, the staff temporarily stores the raw materials in the storage bin 2, and then the staff starts the motor 3 and the heating plate 17. The rotation of the motor 3 causes the drive shaft 4 to rotate, thereby causing the second active bevel gear 12 to drive the second driven bevel gear 13 to rotate, thereby causing the reciprocating screw 6 to rotate, and the rotation of the reciprocating screw 6 causes the threaded block 18 to drive the hot melting groove 22 to move left and right. During the movement, the storage bin 2 will squeeze the baffle plate 9, thereby causing the spring 8 to contract. When the baffle plate 9 is squeezed and moved, the discharge port 7 is opened, and the raw materials fall from the discharge port 7. When the hot melting groove 22 moves to the left, the spring 8 pushes the baffle plate 9 to return to its original position, thereby causing the discharge of the raw materials. The opening 7 is sealed to achieve the purpose of intermittent feeding, avoiding too much feeding at one time to affect the heating and melting efficiency. At the same time, since the hot melt groove 22 reciprocates left and right, the stirring blade 23 can evenly stir the raw material, avoiding the stirring dead angle, and making the raw material heated more evenly. At the same time, the rotation of the first active bevel gear 10 can make the first driven bevel gear 11 rotate, so that the rotating shaft 14 drives the crushing knife 19 to rotate, and the crushing knife 19 can further crush the raw material. The crushed raw material can be heated and melted faster, and the heating plate melts the raw material. After the hot melting is completed, the staff opens the discharge port 20, and the hot-melted raw material is discharged from the discharge port 20.
