Description

Technical Field

[0002] Plastic molding refers to the mixing of different plastic particles in a certain ratio. After the mixed plastic particles are dried to remove moisture, they are transported to the extrusion molding equipment.

[0003] In the related art, in order to improve work efficiency, a temporary storage hopper is often set above the drying equipment. The material in the storage hopper is transported through a connecting pipeline and falls into the drying equipment.

[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0074] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0076] The research found that the disadvantages of the existing technology are: in the related technology, in order to improve work efficiency, a temporary storage hopper is often set above the drying equipment, and the material in the storage hopper is transported through the connecting pipeline and dropped into the drying equipment. When the drying equipment is drying the material, the moisture in the material evaporates due to heat to form water vapor, and the water vapor will flow to the temporary storage hopper along the connecting pipeline.

[0077] The opening and closing valves in traditional connecting pipelines have poor sealing effects, and steam will flow into the temporary storage hopper along the connecting pipeline, causing the material to clump in the connecting pipeline. The two sealing plates arranged opposite to each other need to have a certain thickness so that they can support the material. When the thick sealing plates are flipped upward with the hinge point as the axis, the end walls will interfere with each other. Therefore, in order to avoid interference, there will be a certain gap between the two sealing plates, and the steam will flow upward along the gap.

[0078] Therefore, how to prevent the steam in the drying equipment from flowing into the temporary storage hopper is a technical problem that urgently needs to be solved in the art.

[0079] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0080] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0081] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0082] like Figures 1 to 6 As shown, some embodiments provide an environmentally friendly injection molding central feeding system, including:

[0083] A drying cylinder 1 is provided with a stirring paddle for rotation; the drying cylinder 1 is provided on a support frame, and a driving motor is provided on one side, the driving motor is connected to the stirring paddle for transmission, when the material falls into the drying cylinder 1, the driving motor drives the stirring paddle to rotate to stir the material, accelerate the drying of the material and ensure the balanced drying of the material. A storage cylinder 2 is provided above the drying cylinder 1 and is connected to the drying cylinder 1 through a connecting pipe 3; the storage cylinder 2 is suitable for temporarily storing the material to be dried. The sealing component 4, whose outer end is hinged on the inner wall of the connecting pipeline 3, and the two sealing components 4 are arranged oppositely; the sealing component 4 includes a flip plate 40; the adjusting component 5, which is arranged in the connecting pipeline 3 and is linked with the sealing component 4; after the sealing component 4 is opened, the material is suitable for passing through the adjusting component 5 and falling downward; wherein, when the two sealing components 4 are in a horizontal state, the flip plates 40 arranged oppositely abut against each other to seal the gap between the two sealing components 4; the adjusting component 5 moves upward to push the sealing component 4 to flip upward with the hinge point as the axis to open the connecting pipeline 3; the flip head 50 of the adjusting component 5 flips outward to slow down the material discharge speed in the connecting pipeline 3. Through the setting of the sealing component 4, after it closes the connecting pipeline 3, the steam flows upward along the inner wall of the connecting pipeline 3, and the steam is absorbed by the water absorbing member 43, and the water absorbing member 43 expands and deforms to push the flip plate 40 to flip outward, and the two flip plates 40 are suitable for sealing the gap between the two sealing components 4, thereby preventing the steam from flowing into the storage barrel 2 along the gap between the two sealing components 4. The setting of the adjusting component 5 can adjust the material feeding speed when it pushes open the sealing component 4 to feed the material, thereby avoiding the problem of uneven drying or increased drying time caused by the material being concentrated in a local position in the drying cylinder 1 due to the excessive feeding speed, thereby improving work efficiency.

[0084] Reference Figure 3 The sealing assembly 4 includes: a sealing plate 41, one end of which is hinged to the inner wall of the connecting pipe 3; a torsion spring is sleeved on the outer wall of the hinge axis between the sealing plate 41 and the inner wall of the connecting pipe 3, and the torsion spring is suitable for pushing the sealing plate 41 to make it horizontal, and the two sealing plates 41 arranged opposite to each other are suitable for avoiding the material discharge channel of the connecting pipe 3 to avoid the material in the storage cylinder 2 from being continuously transported to the drying cylinder 1.

[0085] The outer side walls of the sealing plate 41 are adapted to the inner wall of the connecting pipe 3, and the steam will not flow upward along the gap between the sealing plate 41 and the connecting pipe 3; the sealing plate 41 has an accommodating chamber 42 at one end away from the hinge axis, and the accommodating chamber 42 is in the shape of a long strip, and a baffle 44 is slidably arranged in the accommodating chamber 42; a plurality of springs are arranged in the accommodating chamber 42, one end of the spring is fixed to the side wall of the baffle 44, and the spring is suitable for pushing the baffle 44 to move toward the water absorbing member 43.

[0086] The flip plate 40 is hinged on the side of the accommodating chamber 42 away from the inner wall of the connecting pipe 3; the water absorbing member 43 is arranged in the accommodating chamber 42, and the two sides are respectively in contact with the baffle 44 and the flip plate 40; wherein, when the steam in the drying drum 1 flows upward, the water absorbing member 43 absorbs the steam and expands; when the water absorbing member 43 expands, it is suitable for pushing the flip plate 40 to flip outward, so that the two flip plates 40 arranged opposite to each other abut against each other. When the steam does not flow upward, the water absorbing member 43 abuts against the side wall of the flip plate 40, so that the two flip plates 40 arranged opposite to each other fit each other; and when the water absorbing member 43 absorbs the steam and expands and deforms, the water absorbing member 43 squeezes the flip plate 40 to continue flipping outward, so that the two flip plates 40 arranged opposite to each other abut against each other, further improving the air tightness between the two flip plates 40.

[0087] Reference Figure 4 The water absorbing member 43 is in the shape of a long strip and is parallel to the baffle plate 44. The bottom wall of the sealing plate 41 is provided with a plurality of air holes, which are connected to the accommodating cavity 42. When steam passes through the air holes, the water absorbing member 43 is suitable for absorbing steam. Preferably, the water absorbing member 43 can be a sponge or a foamed silicone tube.

[0088] Reference Figure 3 , a support platform 30 is arranged in the connecting pipeline 3, and the support platform 30 is sleeved on the outer wall of the adjustment component 5, and the adjustment component 5 is suitable for moving up and down relative to the support platform 30. The support platform 30 is arranged horizontally, and a through hole is opened in the middle of the support platform 30, and the positioning cylinder 51 is slidably arranged in the through hole; when the sealing plate 41 is opened and the turning head 50 protrudes from the support platform 30, the material in the storage barrel 2 falls downward, and some materials will be accumulated at the support platform 30; and when the positioning cylinder 51 moves downward until the horizontal height of the turning head 50 is lower than the support platform 30, at this time, the material accumulated at the support platform 30 will fall downward along the positioning cylinder 51. When the storage barrel 2 stops conveying materials into the drying cylinder 1, the sealing plate 41 is manually turned over to open it, and the lifting drive drives the positioning cylinder 51 so that the upper surface of the turning head 50 is flush with the support platform 30, and the residual material at the support platform 30 is manually pushed to fall downward along the positioning cylinder 51. Furthermore, the positioning cylinder 51 is a rectangular inscribed circle, so less material can be docked at the support platform 30. In order to reduce the accumulation of materials on the support platform 30, a slope can be set on the upper surface of the support platform 30, and the slope gradually slopes downward from the side of the support platform 30 close to the connecting pipeline 3 to the side of the positioning cylinder 51. Therefore, when the flip head 50 moves downward to a point not higher than the lowest point of the support platform 30, the remaining materials on the support platform 30 will fall down along the slope.

[0089] Reference Figure 2The adjustment assembly 5 includes: a positioning cylinder 51, which is arranged in the connecting pipe 3 for lifting and lowering, and the positioning cylinder 51 is slidably sealed with the through hole; the two flip heads 50 are symmetrically hinged at the upper end of the positioning cylinder 51; an adjustment bar 52, whose bottom wall is arranged on the upper end wall of the positioning cylinder 51, and whose two ends are respectively arranged on the side walls of the two flip heads 50; the adjustment bar 52 is a flexible member, and it is in an arc shape. When the flip head 50 flips outward, the flip head 50 is suitable for stretching the adjustment bar 52, so that the two adjustment bars 52 are formed from a circular shape to an elliptical shape.

[0090] When the material in the drying drum 1 exceeds two-thirds of its storage volume, the turning head 50 turns outward, at which time, the opening between the two adjustment bars 52 is reduced, and the material feeding speed is reduced. The reduced material feeding speed avoids the problem that the material is concentrated at a local position in the drying drum 1 due to the excessive feeding speed; if the material is fed too quickly and concentrated at a local position in the drying drum 1, the stirring paddle needs more stirring time to evenly spread the material in the drying drum 1, and the drying drum 1 also needs more time to dry the accumulated material, thus causing a waste of time and cost damage; however, this embodiment can adjust the feeding speed of the material passing through the positioning drum 51, thereby improving work efficiency.

[0091] When the positioning cylinder 51 moves upward, the flipping head 50 abuts against the bottom wall of the sealing plate 41. The flipping head 50 is suitable for pushing the sealing plate 41 to flip it upward with the hinge point as the axis to open the channel of the connecting pipeline 3 so that the material in the storage cylinder 2 can fall into the drying cylinder 1.

[0092] Furthermore, the outer wall of the connecting pipe 3 is provided with a lifting drive, which is in transmission connection with the positioning cylinder 51, and is suitable for driving the positioning cylinder 51 to move up and down. Two motors are provided at the upper end of the positioning cylinder 51, one motor corresponds to one flip head 50, and the motor is suitable for driving the flip head 50 to flip inward or outward with the hinge point as the axis.
