Description

Technical Field

[0001] The present application relates to the technical field of foaming machine design, and in particular to a foaming machine feeding system. Background Art

[0002] Pre-foaming is to expand the expandable raw materials to a certain extent by heating, so that the density of the product can be lower during molding, and the density gradient can be reduced, so that the foamed product is uniform. The heating methods for the pre-foaming process include water vapor, hot water, hot air and infrared rays.

[0003] Since the refilling barrel of the foaming machine is usually set at a relatively high position, it is difficult for workers to directly reach it while standing on the ground. The raw materials will be sent to the refilling barrel by the auger conveyor for temporary storage before foaming. In order to meet the total amount of foamed materials in a batch of foaming, excess raw materials are usually sent to the refilling barrel, so the excess raw materials will remain in the refilling barrel. The auger conveyor is generally unable to reverse the raw materials from the high place downward, so the raw materials in the refilling barrel cannot be extracted and transported back to the ground for recycling, resulting in a waste of raw materials. When the raw materials of another material are input into the refilling barrel, the raw materials of different materials will be mixed together, affecting the quality of the foamed finished product. Summary of the invention

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below.

[0027] Reference Figure 1-3 ,

[0028] A foaming machine feeding system includes: a weighing device 1, a temporary storage bucket 2, a foaming machine body 3, a first pipeline 4, a blower 5 and a second pipeline 6. The weighing device 1 forms a raw material input port with an upward opening and a raw material output port with a downward opening. Workers add raw materials into the weighing device 1 from the raw material input port, and the weighing device 1 is used to weigh the raw materials added by the workers. The temporary storage bucket 2 forms a bucket mouth and a discharge port, and the bucket mouth faces upward and docks with the raw material output port. The weighed raw materials are added to the temporary storage bucket 2 through the raw material output port and the bucket mouth for standby use. The foaming machine body 3 uses an existing integrated feed barrel 31 and foaming tank 32 product, and the lower end of the feed barrel 31 docks with the foaming tank 32. One end of the first pipeline 4 is in airtight communication with the discharge port of the temporary storage bucket 2, and the other end is in airtight communication with the feed barrel 31. The blower 5 forms a first vent 51 and a second vent 52. The second vent 52 is connected to the outside air. The outside air refers to the air around the blower 5. The first vent 51 is in air-tight communication with one end of the second pipe 6, and the other end of the second pipe 6 is in air-tight communication with the replenishing barrel 31. The blower 5 is an existing product with a two-way blowing capability. When it is necessary to add raw materials to the replenishing barrel 31, the blower 5 sucks out the gas in the replenishing barrel 31 through the second pipe 6, and the gas is finally discharged to the outside through the second vent 52. The air pressure in the replenishing barrel 31 is reduced to form a pressure difference with the outside air, and the outside air presses the raw materials in the temporary storage bucket 2 into the replenishing barrel 31 through the first pipe 4. When it is necessary to return the raw materials remaining in the replenishing barrel 31 to the temporary storage bucket 2, the blower 5 inhales the outside air through the second air vent 52 and presses the air into the replenishing barrel 31 through the second pipe 6. The air pressure in the replenishing barrel 31 increases to exceed the outside air pressure, so as to press the raw materials in the replenishing barrel 31 back to the temporary storage bucket 2 through the first pipe 4.

[0029] Specifically, the feed barrel 31 includes: a barrel body 311 and a first connecting pipe 312. One end of the first connecting pipe 312 forms a plurality of sieve holes 3121, and extends into the barrel body 311 to communicate with the barrel body 311. The other end of the first connecting pipe 312 is connected to the second pipeline 6. When the blower 5 sucks gas from the feed barrel 31, the raw material moves under the action of the wind. The sieve holes 3121 on the first connecting pipe 312 ensure the flow of gas and prevent the raw material from moving into the blower 5 through the second pipeline 6 to damage the blower 5.

[0030] Specifically, the feed barrel 31 further includes: a second connecting pipe 313. One end of the second connecting pipe 313 is connected to the lower part of the barrel body 311, and the other end of the second connecting pipe 313 is connected to the first pipeline 4 in a sleeve connection. The second connecting pipe 313 and the barrel body 311 form a communicating vessel, and the first connecting pipe 312 is connected to the upper end of the barrel body 311. Therefore, when the first connecting pipe 312 is as far away as possible from the raw material at the lower part of the feed barrel 31, the gas can press the raw material from the second connecting pipe 313 into the first pipeline 4 as completely as possible.

[0031] Specifically, the first pipe 4 and the second pipe 6 are both flexible pipes, so that when arranging the feeding device, workers can arbitrarily bend the first pipe 4 and the second pipe 6 to reduce the space occupied by the feeding device.

[0032] Specifically, the weighing device 1 includes: a raw material storage hopper 11 and a weighing hopper 12. The raw material storage hopper 11 is a funnel with a valve at the output port, and the weighing hopper 12 uses an existing product. The output port of the raw material storage hopper 11 is connected to the input port of the weighing hopper 12, and the output port of the weighing hopper 12 forms a raw material output port. When a worker adds raw materials to the raw material storage hopper 11, the valve at its output port is closed. When weighing is required, the worker opens the valve, and the raw materials enter the weighing hopper 12 through the output port. After weighing, the weighing hopper 12 outputs the raw materials to the temporary storage hopper 2.

[0033] Specifically, the raw material storage bucket 11 , the weighing bucket 12 and the temporary storage bucket 2 are arranged one by one from top to bottom to reduce the horizontal space occupied by the weighing device 1 .

[0034] Specifically, it also includes: a bracket 7. The bracket 7 is placed on the ground, the raw material storage bucket 11 and the weighing bucket 12 are respectively fixed to the bracket 7 by bolts, and the temporary storage bucket 2 is placed on the ground. After the raw materials are sent back to the temporary storage bucket 2 from the replenishing bucket 31 through the first pipeline 4, the worker can pick up the temporary storage bucket 2 and then pour the raw materials in the temporary storage bucket 2 back into the raw material storage bucket 11 for standby use.
