[0025] Example:

[0026] Reference Figure 1-Figure 4A material receiving funnel device for hot melt adhesive production includes a material receiving funnel body 1, a material discharge pipe 102 is fixedly arranged at the bottom of the material receiving funnel body 1, and a heating channel 103 with a spiral structure is opened in the material receiving funnel body 1, and an inlet pipe and a discharge pipe are fixedly arranged on the outer wall of the material receiving funnel body 1, and the two ends of the heating channel 103 are respectively connected with the inlet pipe and the discharge pipe, and valves are fixedly arranged on the inlet pipe and the discharge pipe, so that hot water, steam or hot oil can be introduced into the inlet pipe, and then the heating medium flows along the heating channel 103, which can heat and keep the inside of the material receiving funnel body 1 warm, and finally flow out from the discharge pipe, thereby improving the use effect, and a heat preservation layer 101 is fixedly arranged in the material receiving funnel body 1, which can improve the heat preservation effect and reduce the heat loss. It also includes a rotating shaft 3 that is rotatably arranged in the receiving funnel body 1, and a spiral blade 301 is fixedly arranged on one end of the rotating shaft 3 that extends into the discharge pipe 102, and the outer wall of the spiral blade 301 away from the rotating shaft 3 is abutted against the inner wall of the discharge pipe 102. When in use, by rotating the spiral blade 301 in the discharge pipe 102, on the one hand, the raw materials adhering to the inner wall of the discharge pipe 102 can be scraped off to prevent the raw materials from clogging the discharge pipe 102 after solidification, thereby affecting normal use. On the other hand, during the discharge process, the rotation speed of the spiral blade 301 can be controlled to adjust the discharge speed and improve the use effect.

[0027] Reference Figure 1 , Figure 2 and Figure 4 A top cover 2 is removably provided on the top of the receiving funnel main body 1, and the top cover 2 is fixed to the top of the receiving funnel main body 1 by bolts or buckles. Here, we use a buckle method to fix the top cover 2 to the top of the receiving funnel main body 1, and the fixing effect is reliable and the assembly and disassembly are convenient. A first sealing gasket 204 is fixedly provided on the inner wall of the top cover 2, and the bottom of the first sealing gasket 204 is abutted against the top of the receiving funnel main body 1, and a handle 201 is fixedly provided on the top cover 2. When in use, by assembling and disassembling the top cover 2 on the top of the receiving funnel main body 1, dust and the like can be reduced from entering the receiving funnel main body 1, thereby improving the use effect.

[0028] Reference Figure 1 and Figure 2 A motor 303 is fixedly arranged on the top of the top cover 2, and the rotating shaft 3 is fixedly connected to the output end of the motor 303, and a first scraper 302 is fixedly arranged on the rotating shaft 3 through a fixing rod 304, and the first scraper 302 is against the inner wall of the receiving funnel body 1. There is at least one group of first scrapers 302, and here we symmetrically arrange two groups. When in use, by driving the spiral blade 301 to rotate by the rotating shaft 3, the first scraper 302 can be brought to clean the inner wall of the receiving funnel body 1 at the same time, which can avoid the raw material solidifying on the inner wall of the receiving funnel body 1 and reduce the waste of raw materials.

[0029] Reference Figure 1 , Figure 2 and Figure 4 A feed pipe 202 is fixedly arranged on the top cover 2, a sealing cover 203 is threadedly connected to the top of the feed pipe 202, and a second sealing gasket 205 is fixedly arranged on the inner wall of the sealing cover 203, and the bottom of the second sealing gasket 205 is abutted against the top of the feed pipe 202.

[0030] Reference Figure 2 and Figure 4 An annular seat 4 is rotatably arranged on the outer wall of the output end of the feed pipe 202. The upper end of the annular seat 4 forms a limit connection with the outer wall of the feed pipe 202, so that the annular seat 4 can be rotated on the outer wall of the feed pipe 202, and the axial displacement of the annular seat 4 is constrained. The lower end of the annular seat 4 is arranged at the lower end of the feed pipe 202, so that the structure inside the feed pipe 202 can be connected to the annular seat 4.

[0031] A second scraper 401 is rotatably arranged in the feed pipe 202, and one end of the second scraper 401 extending out of the feed pipe 202 is fixedly connected to the inner wall of the valve of the annular seat 4 through a connecting rod 403. One end of the connecting rod 403 is vertically fixed to the second scraper 401, and the other end is fixedly connected to the lower end of the annular seat 4. In this way, when the annular seat 4 rotates, the second scraper 401 can be driven to rotate in the feed pipe 202.

[0032] A driving unit for driving the annular seat 4 to rotate is provided in the receiving hopper body 1, and two groups of second scrapers 401 are symmetrically provided, and the other ends of the two groups of second scrapers 401 are fixedly connected by a crossbar. When in use, the annular seat 4 is driven to rotate by the driving unit, and when the annular seat 4 is driven, the second scraper 401 can be driven to rotate coaxially, thereby cleaning the inner wall of the feed pipe 202, preventing the raw material from adhering to the inner wall of the feed pipe 202, causing the feed pipe 202 to be blocked, and affecting normal use.

[0033] Reference Figure 2 and Figure 4, the driving part can use a motor to drive the annular seat 4 to rotate. Here, we design the driving part as follows: a gear 402 is fixedly arranged on the outer wall of the annular seat 4, and the gear 402 is coaxially fixed to the annular seat 4. A transfer rod 501 is vertically fixedly arranged on the fixed rod 304, and a gear ring 5 is fixedly arranged on the top of the transfer rod 501, and the gear ring 5 is meshed with the gear 402, and the gear ring 5 is a quarter circle, and the axis of the gear ring 5 coincides with the axis of the rotating shaft 3. When in use, when the rotating shaft 3 rotates, the gear ring 5 can be driven to rotate around the axis of the rotating shaft 3. When the gear ring 5 rotates to mesh with the gear 402, the annular seat 4 can be driven to rotate intermittently, so that the second scraper 401 can be driven to clean the inner wall of the feed pipe 202, thereby improving the use effect.
