Abstract
The invention provides a powder conveying mechanism, which comprises a cylinder and a conveying screw arranged in the cylinder. A feeding hole is arranged at one end of the cylinder. A discharging hole is arranged at the other end of the cylinder. A homogenization section screw edge head is arranged on the conveying screw at the discharging end. The homogenization section screw edge head is composed of four strands of screw edges that screws are in mutual 90 DEG. The homogenization section screw edge head at the head part of the screw is uniformly divided into the four strands of screw edges that the screws are in mutual 90 DEG, so that powder sent from the previous section is uniformly divided into four strands of fine branches through the four screw edges and then uniformly output from a material hole at the front end of the cylinder. The periodic conveying disadvantage of the conveying screw in every rotating cycle in the original single-screw edge conveying process is eliminated; therefore, the powder can be uniformly discharged from the front end of the cylinder; and the ideal powder conveying mode is achieved.
Description
Technical field
The present invention relates to a kind of multi-layer co-extruded heat shrinkage film powder transport, relate in particular to a kind of single screw rod powder conveying mechanism.
Background technology
At present; In the multi-layer co-extruded heat shrinkage film equipment; Need powder is carried and feeding, to realize goods processing, because traditional single screw feeder structure is the feeding of single spiral shell rib at the screw front end outgoing position; Will inevitably cause the swing circle property blanking of powder, follow-up raw material mixed bring totally unfavorable influence with screw rod.
Therefore, how realize the even conveying of powder, to the manufacturing process important influence of entire equipment through single screw feeder.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of multi-layer co-extruded heat shrinkage film powder conveying mechanism is provided.
The object of the invention is realized through following technical scheme:
The powder conveying mechanism; Comprise machine barrel and the feeding spiro rod that places machine barrel, an end is provided with charging aperture on the said machine barrel, and the other end is provided with discharging opening; Characteristics are: the feeding spiro rod of discharge end position is provided with homogenizing zone spiral shell rib head, and said homogenizing zone spiral shell rib head is made up of the spiral shell rib that four strands of spiral shell elements are mutually 90 degree.
Further, above-mentioned powder conveying mechanism, wherein, said feeding spiro rod is single screw-rod structure.
The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:
Be divided into the spiral shell rib that four spiral shell elements are mutually 90 degree through the homogenizing zone spiral shell rib head with screw head, the powder that leading portion is sent here is divided into four strands of ramuscule streams by four spiral shell ribs, evenly exports from machine barrel front end material mouth; Eliminated the defective of the defeated material of feeding spiro rod revolution one cycle property in the defeated material process of the single spiral shell rib of script; Powder can be seen off from the machine barrel front end equably; Reach desirable powder transport model; Promoted the uniformity that the grain powder mixes in powder and the tube effectively, the quality of end article has been played sound assurance.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: structural representation of the present invention;
Fig. 2: the structural representation of feeding spiro rod.
The specific embodiment
As shown in Figure 1, the powder conveying mechanism comprises machine barrel 2 and the feeding spiro rod 1 that places machine barrel; Feeding spiro rod 1 is single screw-rod structure, and an end is provided with charging aperture on the machine barrel 2, and the other end is provided with discharging opening; The feeding spiro rod of discharge end position is a homogenizing zone spiral shell rib head; As shown in Figure 2, homogenizing zone spiral shell rib head is made up of the spiral shell rib that four strands of spiral shell elements are mutually 90 degree, i.e. the first spiral shell rib 4, the second spiral shell rib 5, the 3rd spiral shell rib 6 and the 4th spiral shell rib 7.
During the defeated material of feeding spiro rod 1 rotation, the powder of leading portion is divided into four strands, exports powder equably, promoted the uniformity that a powder mixes in powder and the tube effectively, the quality of end article has been played sound assurance by four spiral shell rib grooves through four spiral shell ribs.
Be divided into the spiral shell rib that four spiral shell elements are mutually 90 degree through the homogenizing zone spiral shell rib head with screw head, the powder that leading portion is sent here is divided into four strands of ramuscule streams by four spiral shell ribs, evenly exports from machine barrel front end material mouth; Eliminate the defective of the defeated material of feeding spiro rod revolution one cycle property in the defeated material process of the single spiral shell rib of script, powder can be seen off from the machine barrel front end equably, reached desirable powder transport model.
What need understand is: the above only is a preferred implementation of the present invention; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
Claims (2)
1. powder conveying mechanism; Comprise machine barrel and the feeding spiro rod that places machine barrel; An end is provided with charging aperture on the said machine barrel; The other end is provided with discharging opening, it is characterized in that: the feeding spiro rod of discharge end position is provided with homogenizing zone spiral shell rib head, and said homogenizing zone spiral shell rib head is made up of the spiral shell rib that four strands of spiral shell elements are mutually 90 degree.
2. powder conveying mechanism according to claim 1 is characterized in that: said feeding spiro rod is single screw-rod structure.
