Description

Technical Field

[0001] The present application relates to the technical field of foaming machine design, and in particular to a raw material weighing device for a foaming machine. Background Art

[0002] Pre-foaming is to expand the expandable beads 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] When foaming raw materials, it is usually necessary to control the total amount of raw materials delivered to the foaming machine. The common raw material weighing device adopts a structure in which a funnel is placed on a weighing bucket. When the funnel discharges the material into the weighing bucket, due to the height difference between the two, part of the raw materials fall and remain in the weighing bucket, and the other part of the raw materials collide with the weighing bucket and pop out of the weighing bucket. After multiple weighings, the total amount of raw materials popped out of the weighing bucket is relatively large, resulting in a waste of raw materials. Summary of the invention

[0027] Reference Figure 1-3 ,

[0028] A raw material weighing device for a foaming machine comprises: a foaming machine body 1, a weighing bucket 2, a valve 3, a filling cover 4 and a moving assembly 5. The foaming machine body 1 is a product of the prior art, and is used for foaming the raw materials. The foaming machine body 1 forms a material feeding interface for receiving the raw materials. The weighing bucket 2 is a product of the prior art, and has a bucket mouth formed at the upper end and a discharge port formed at the lower end, and the discharge port faces the material feeding interface. The valve 3 is a slide valve, and the valve 3 is installed at the discharge port, and is used to control the discharge of the weighing bucket 2. A filling port is formed at the lower end of the filling cover 4, and the filling port cooperates with the bucket mouth. The filling cover 4 is externally connected to a raw material pump through a pipeline, and the raw material pump pumps the raw material into the filling cover 4. The moving assembly 5 enables the filling cover 4 to reciprocate between a first position and a second position. When the filling cover 4 is in the first position, the filling port is docked with the bucket mouth, and at this time, the filling cover 4 and the weighing bucket 2 are tightly docked to prevent the raw material from popping out of the weighing bucket 2 during the filling process. When the filling cover 4 is located at the second position, the filling port is separated from the bucket port, so that the worker can directly observe that the filling cover 4 is not currently filling the weighing bucket 2 with raw materials.

[0029] Specifically, the foaming machine body 1 includes: a hopper 11, a foaming cabinet 12 and a fluidized bed 13. The hopper 11 forms a material feeding interface, the hopper 11 is connected to the foaming cabinet 12, and the foaming cabinet 12 is connected to the fluidized bed 13. After the raw materials are weighed, the worker opens the valve 3, and the raw materials fall from the weighing hopper 2 into the hopper 11, and then enter the foaming cabinet 12 from the hopper 11 for foaming, and finally are processed in the fluidized bed 13 to become finished products.

[0030] Specifically, the moving assembly 5 includes: a guide rail 51 and a slider 52. The guide rail 51 is a magnetic rail, the slider 52 is slidably connected to the guide rail 51, the upper end of the filling cover 4 is fixed to the slider 52 by bolts, and the external power supply supplies power to the guide rail 51 to generate a magnetic field, thereby pushing the slider 52 to slide along the guide rail 51. When the slider 52 moves to one end of the guide rail 51, the filling cover 4 is located at the first position. When the slider 52 moves to the other end of the guide rail 51, the filling cover 4 is located at the second position.

[0031] In one embodiment, the filling cover 4 includes: a cover body 41 and a conical sleeve 42. The side of the cover body 41 is externally connected to a raw material pump through a pipeline, and the lower end of the cover body 41 forms a filling port. The upper end of the conical sleeve 42 forms a large opening, and the lower end has a small opening. The large opening of the conical sleeve 42 is docked with the filling port and fixed by gluing. When the cover body 41 moves to the first position, the filling port is docked with the bucket mouth, and the conical sleeve 42 extends into the interior of the weighing bucket 2. The raw material pumped into the cover body 41 by the raw material pump enters the funnel 11 through the conical sleeve 42, further improving the airtightness of the docking between the filling cover 4 and the weighing bucket 2 to prevent the raw material from leaking out.

[0032] Specifically, the guide rail 51 is horizontally placed on the opposite side of the bucket mouth, and the length direction of the guide rail 51 is parallel to the plane where the bucket mouth is located, that is, the guide rail 51 is horizontally placed above the bucket mouth and parallel to the ground, and the conical sleeve 42 is made of a flexible material, which is rubber in this embodiment. When the cover body 41 moves laterally relative to the weighing bucket 2, staggers and docks, the conical sleeve 42 undergoes elastic deformation to avoid damage.

[0033] Specifically, it also includes: a box body 6. The guide rail 51 is fixed to the upper part of the box body 6 by bolts, the weighing bucket 2 is welded and fixed to the middle part of the box body 6, and the funnel 11 is welded and fixed to the lower part of the box body 6. When the filling cover 4 moves between the first position and the second position, the filling port is always opposite to the funnel 11, so that when the filling cover 4 and the weighing bucket 2 are staggered, the remaining raw materials in the filling cover 4 will fall into the funnel 11, and then be used by the foaming cabinet 12, thereby avoiding the waste of raw materials.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
