CN2478960Y - Sheet former for use in equipment of making degradable tableware - Google Patents

Abstract

The utility model relates to a production facility of packing products, in particular to a sheet former of manufacture equipments of dinner sets, and grain masses such as corn, rice, Chinese sorghum and the like are used as degradable raw materials of the manufacture equipment of dinner sets. An inlet end of the sheet former and an extrusion worm machine of materials are fixed tightly and connected with each other. The utility model is characterized in that the sheet former is formed by the connection of a squeezing and shooting body of materials 1 and a sheets squeezing-out body 2, wherein the inlet end of the squeezing and shooting body is of round shape, the outlet end is a slotted groove which is wide at both ends and narrow in the middle, and the groove width of the inlet end of the sheet squeezing-out body is larger than that of the outer end. The utility model has the advantages of simplification of devices and spontaneous foaming and the like.

Description

Device in blocks in the degradable dinner set production facilities

The utility model relates to the packing material manufacturing equipment, particularly is fit to starch based, does the degradable raw material as corn, rice, jowar etc. and makes sheet forming device in the tableware equipment.

Utilize degradable dinner set that plant straw or foodstuff starch make or packing material in order to substitute the non-degradable plastic product, become the environmental protection trend.In the common method for making, the raw material pulverized is added deliver to the rolling press top roll after auxiliary material such as adhesives stirs and be pressed into sheet material, deliver to compression molding on the make-up machine then.As 99122274.1 " all biological degradation type disposable tableware, its production technology and the specialized equipments " of applying for Chinese patent disclose this technical scheme, and its shortcoming is the equipment more complicated, need special-purpose rolling press in blocks.

The purpose of this utility model provide a kind of can be automatically in flakes and expanded sheet forming device with the degradable material through extruding.

The extruding end strength joint of the material extruser in entrance point of the present utility model and the production facilities, it is characterized in that forming by crowded beam of material and sheet material squeeze-up joint, it is rounded wherein to squeeze the beam entrance point, exit end is a slot shape, and the groove width of sheet material squeeze-up entrance point is greater than the groove width of exit end.

Squeeze middle narrow, two head breadths of slot of beam exit end.

The direct strength joint of the extruding end of the utility model and material extruser and directly in flakes, saved the rolling press in the conventional production equipment has improved work efficiency, has reduced productive costs.The exit end of especially crowded beam is narrow in the middle of making, the line of rabbet joint of two head breadths, make the middle part big to the material resistance, be forced to two and disperseed, make the crowded material that is mapped to the moulding squeeze-up become even, make that the sheet thickness of extruding from the squeeze-up exit end is even, solved from round mouth and entered directly the thin difficult problem in sheet material both sides when the vertical masonry joint groove is extruded.In addition, extruser can squeeze material because of rubbing and produce high temperature when high speed revolution advances material, when material is extruded a contact outside air from the formed body exit end, promptly can produce the expansion effect of puffed rice naturally, has omitted the foam process in the traditional handicraft.

In the accompanying drawing, Fig. 1 is the utility model embodiment section drawing, and Fig. 2 is Fig. 1 birds-eye view, and Fig. 3 squeezes the beam upward view among Fig. 1, and Fig. 4 is a moulding squeeze-up birds-eye view among Fig. 1, and Fig. 5 is Fig. 4 back view, and Fig. 6 is an A-A section drawing behind Fig. 5 half-twist.

Be described further below in conjunction with accompanying drawing.

Present embodiment squeezes beam 1 by material and sheet forming squeeze-up 2 joints form.The entrance point 4 that wherein squeezes beam 1 is rounded, closes in order to be connected with extruser round exit end spiral shell, squeezes the exit end of beam 1 and makes two head breadths, middle narrow slot 5.The rectangular inlet end 7 of sheet material squeeze-up 2 and exit end slot 5 tight joint of crowded beam 1 make the slurry that evenly ejects from slot 5 enter this entrance point 7 equably.The exit end 3 of squeeze-up 2 is made the rectangle slot, and its ratio with entrance point 7 groove widths is about 1: 10.Figure mesopore 6 is used for screw rod and extruser is spirally connected.

Claims (2)

1, device in blocks in a kind of degradable dinner set production facilities, the extruding end strength joint of entrance point and material extruser, it is characterized in that forming by crowded beam (1) of material and sheet material squeeze-up (2) joint, the entrance point (4) that squeezes beam (1) is rounded, exit end (5) is slot shape, and the groove width of the entrance point (7) of sheet material squeeze-up (2) is greater than the groove width of exit end (3).

2, device in blocks according to claim 1, middle narrow, two head breadths of exit end (5) slot that it is characterized in that squeezing beam (1).
