A screw 10 is disposed inside the cylindrical barrel 20, and the screw 10 is rotatable relative to the barrel 20 and is advanced and retracted in the front-rear direction. The rear end portion of the screw 10 is connected to an actuator 410 of the driving unit 40 constituted by a cylinder or the like. The screw 10 advances and retreats in the front-rear direction by the driving of the actuator 410. The gear 151 fixed to the screw 10 in a flange shape is provided in the middle of the screw 10. The gear 151 is engaged with a pinion 421, and the pinion 421 is fixed to an output shaft of a rotary unit 420 of a driving unit 40 configured by a motor or the like.

As shown in fig. 1, the hopper 50 is connected to a hopper connection portion 210, and the hopper connection portion 210 is provided on the peripheral surface of the rear portion of the tub 20 at the hopper connection portion 210. The internal space of the hopper 50 communicates with a material conveying space 204 (see fig. 2 and the like) formed between the outer peripheral surface of the screw 10 and the inner peripheral surface of the barrel 20, and a resin material as a powder is supplied from the hopper 50 to the material conveying space 204. The fluid supply portion 60 is connected to the rear end portion of the screw 10. The fluid supply unit 60 supplies temperature-controlled water as a fluid to the flow paths (the inflow side flow paths 121 and 171 and the outflow side flow paths 131 and 161) formed in the screw 10, and discharges the temperature-controlled water flowing through the flow paths. The cutter portion 30 has a shutter type cutter 310, and cuts off the resin material fed to the tip end portion of the material feeding space 204.
Next, the screw 10 is specifically described. As shown in fig. 2 and the like, the screw 10 has a front end 110 and a base 150. As shown in fig. 3, the distal end portion 110 includes a spiral portion 1101 and a spiral distal end portion 1102 detachably fixed to the distal end portion of the spiral portion 1101 by a sealing member 1103. Spiral teeth are formed on the outer peripheral surface of the spiral portion 1101. The front end of the base 150 is connected to the rear end of the front end 110, and the base 150 has an enlarged diameter compared to the front end 110. As shown in fig. 2, the pipe member 140 is fixedly disposed at an axial center position of the base 150 with respect to the base 150. The tip 110 and the pipe member 140 have inflow side flow passages 121 and 171 and outflow side flow passages 131 and 161 described later, and the inflow side flow passages 121 and 171 and the outflow side flow passages 131 and 161 rotate integrally with the screw 10.
The gear 151 protruding in a flange shape from the base 150 is provided at a position near the rear of the front end portion of the base 150 connected to the front end portion 110 so as to be rotatable integrally with the base 150. The portion of the screw 10 on the rear side of the gear 151 of the base 150 is rotatably supported by a rotation support portion 650 via a bearing, and the rotation support portion 650 is fixed to a supply base 610 in which a supply flow passage 621, which is a temperature-adjusting flow passage, is formed in the fluid supply portion 60.
The screw 10 includes an internal temperature adjustment portion having an internal flow passage for circulating temperature adjustment water formed inside the screw 10. As shown in fig. 2, the internal flow path extends from the base 150 to the tip 110 of the screw 10, and includes inflow side flow paths 121 and 171 and outflow side flow paths 131 and 161. The inflow side flow passages 121, 171 extend from the end of the base 150 of the screw 10 to the vicinity of the tip 113 having a pointed shape in the outer shape of the tip 110 of the screw 10 in the axial center position of the screw 10.
More specifically, in the front end 110 of the screw 10, an inflow-side flow channel 121 is formed at the axial position of the front end 110, and in the rear of the screw 10, an inflow-side flow channel 171 is formed at the axial position of the pipe member 140 fixed to the base 150, and the rear end of the inflow-side flow channel 121 is connected to the front end of the inflow-side flow channel 171. As shown in fig. 7, the rear end portion of the inflow side flow passage 171 communicates with a flow passage 175 extending in the diameter direction of the pipe member 140.
As shown in fig. 7, the flow passage 175 is opposed to the supply flow passage 621 which constitutes the fluid supply portion 60 and is formed in the supply base portion 610 by rotation of the screw 10. When the flow passage 175 is not opposed to the supply flow passage 621, the flow passage 175 and the supply flow passage 621 communicate with each other via a coating groove 176, and the coating groove 176 is formed so as to circumferentially surround the circumferential surface of the pipe member 140 of the screw 10, and communicates one opening of the flow passage 175 extending in the diameter direction with the other opening. The coating groove 176 forms a part of the inflow side flow passage 121. Therefore, the supply flow path 621 and the inflow side flow path 171 are always in communication, and when the screw 10 rotates, the temperature-controlled water can always flow from the supply flow path 621 into the inflow side flow path 171, and when the screw 10 rotates, the flow path 175 faces the supply flow path 621, and the temperature-controlled water flows from the supply flow path 621 into the inflow side flow path 171.
As shown in fig. 2 to 7, the outflow side flow paths 131 and 161 are formed at positions radially outward of the screw 10 of the inflow side flow paths 121 and 171, and extend from the same position as the front end 110 of the inflow side flow path 121 to a position closer to the front end 110 of the screw 10 than the rear end of the tube member 140 of the base 150 of the screw 10 as shown in fig. 2, as shown in fig. 2 and 3.
More specifically, as shown in fig. 3, 4, and the like, in the front end portion 110 of the screw 10, the outflow side flow passage 131 communicates with the inflow side flow passage 121 via 4 through holes 125. As shown in fig. 4, the outflow side flow path 131 is formed around the inflow side flow path 121 in a coaxial positional relationship with the inflow side flow path 121 as a center. And the outflow-side flow passage 131 extends to the rear end portion of the front end portion 110. At the rear of the screw 10, as shown in fig. 6 and the like, 4 outflow side flow channels 161 are formed so as to surround the inflow side flow channel 171 in a coaxial positional relationship with the inflow side flow channel 171 as the center, and so as to be parallel to the axial center of the screw 10, and the inflow side flow channel 171 is formed at the axial center position of the pipe member 140 fixed to the base 150. The 4 outflow side flow passages 161 are arranged at equal intervals in the circumferential direction of the pipe member 140, and the rear end portions of the outflow side flow passages 161 extend to a position closer to the front end than the rear end portions of the inflow side flow passages 171.
The rear end portions of the 4 outflow side passages 161 are connected to and communicate with the discharge concave portions 165 recessed inward in the radial direction of the pipe member 140, respectively. As shown in fig. 6, by rotation of the screw 10, the discharge recess 165 is opposed to a discharge flow path 631 which constitutes the fluid supply unit 60 and is formed on the supply base 610. When the discharge concave portion 165 is not opposed to the discharge flow path 631, the discharge concave portion 165 and the discharge flow path 631 communicate with each other via the coating groove 166, and the coating groove 166 is formed so as to surround the pipe member 140 by one round and communicates the openings of the 4 discharge concave portions 165. Therefore, the discharge flow path 631 and the discharge concave portion 165 are always in communication, and when the screw 10 rotates, the temperature-controlled water can always flow out from the discharge concave portion 165 to the discharge flow path 631, and when the screw 10 rotates, the discharge concave portion 165 faces the discharge flow path 631, and the temperature-controlled water flows out from the discharge concave portion 165 to the discharge flow path 631. The coating groove 166 forms a part of the outflow-side flow passage 161.
In the material measuring instrument 1 having the above configuration, the resin material supplied as follows is stirred, soaked, transported, and measured.
First, the granular resin material is supplied to the hopper portion 50, the temperature-controlled water is supplied to the external tank 201, and the temperature-controlled water is supplied from the supply flow passage 621 of the fluid supply portion 60 to the inflow side flow passage 171 through the flow passage 175 and the coating groove 176. The temperature-adjusting water supplied to the inflow side flow passage 171 flows forward in the inflow side flow passage 171 and flows into the inflow side flow passage 121. The temperature-controlled water flows into the outflow side flow path 131 through the through hole 125 at the front end portion of the inflow side flow path 121, flows backward, and flows into the 4 outflow side flow paths 161. The temperature-controlled water further flows rearward, flows out through the discharge recess 165 and the coating groove 166 to the discharge flow path 631 formed in the supply base 610, and is discharged from the fluid supply unit 60 to the outside of the material meter 1.
Next, the gear 151 and the screw 10 are integrally rotated by the rotation of the pinion 421 of the rotation section 420 of the driving section 40. The granular resin material supplied to the material conveying space 204 is conveyed forward while being cut and stirred by the rotation of the helical rib 111 of the tip 110 of the screw 10.
At this time, as described above, since the temperature-adjusting water is supplied to the external tank 201 and the temperature-adjusting water flows through the inflow side flow passage 121 and the outflow side flow passage 131, the resin material conveyed by the screw 10 in the material conveying space 204 is heated and adjusted from both the barrel 20 side and the screw 10 side by the heat of the temperature-adjusting water, and the internal temperature of the resin material is equalized. In this way, the resin material becomes a solidified powder in a semi-molten state.
Then, by driving the actuator 410 of the driving unit 40, the screw 10 advances forward, and the resin material conveyed to a state where the resin material is cured forward of the screw 10 is pushed forward and conveyed to the shutter type cutter 310 of the cutter unit 30. Then, the resin material is cut by the shutter blade 310, and a sheet of the resin material in a cured state is formed, which is measured to be a predetermined amount.
According to the material meter 1 of the conveying device of the present embodiment having the above-described structure, the following effects can be obtained.
The material gauge 1 of the present embodiment includes: the screw 10 is a screw 10 to which a material is supplied, and the material is supplied while being stirred by rotation of the screw 10; and an internal temperature adjustment unit (an inflow side flow path 121 and an outflow side flow path 131) provided inside the screw 10, for adjusting the internal temperature of the material conveyed by the screw 10 to thereby homogenize the temperature of the material. With this structure, the resin material conveyed by the screw 10 in the material conveying space 204 can be heated from the screw 10 side and adjusted in temperature, and the internal temperature of the resin material can be equalized. That is, by the screw metering method by the screw 10, heat can be uniformly transferred to the pellets.
Furthermore, the apparatus for forming the sheet does not need to be preheated in advance. Further, the heat uniformity can be achieved by directly preheating the screw 10. Further, by changing the diameter of the screw 10, the diameter and the capacity of the plurality of kinds of sheet bodies can be adjusted. In addition, by changing the screw material, a plurality of materials can be corresponded.
The internal temperature adjusting portion includes an inflow side flow path 121 and an outflow side flow path 131 which are flow paths for adjusting temperature water, which is a fluid for adjusting temperature, formed inside the screw 10. With this structure, the temperature of the resin material on the screw 10 side can be easily adjusted by the temperature-adjusting water flowing through the flow passage.
Further, the inflow side flow path 121 and the outflow side flow path 131 rotate integrally with the screw 10. With this configuration, when the granular resin material is heated while stirring, the resin material can be reliably heated and temperature-controlled following the rotation of the resin material, and the uniformity of the temperature of the resin material can be easily achieved.
The flow passage has an inflow side flow passage 121 formed at the axial center position of the screw 10; and an outflow side flow path 131 formed at a position radially outward of the screw 10 of the inflow side flow path 121. With this structure, the temperature-adjusting water can be continuously circulated in the screw 10, and the temperature adjustment of the resin material can be stably and continuously performed.
When the screw 10 rotates, fluid can always flow into the inflow-side flow path 121, and when the screw 10 rotates, fluid can always flow out of the outflow-side flow path 131. With this structure, the continuous circulation of the temperature-adjusting water can be ensured in the screw 10, and the temperature adjustment of the resin material can be performed more stably and continuously.
The plurality of outflow-side flow passages 161 are formed parallel to the axial center of the screw 10. With this configuration, the temperature-controlled water flowing into the annular outflow-side flow passage 131 can be split into the plurality of outflow-side flow passages 161.
The inflow side flow passage 171 includes a coating groove 176, which is a groove that surrounds the circumferential direction of the screw 10. With this structure, it is possible to easily realize a structure in which the temperature-adjusting water can always flow into the inflow side flow passage 171 when the screw 10 rotates.
Further, an external temperature adjusting portion (external groove 201, cover portion 202) for adjusting the external temperature of the resin material is provided. In this way, the resin material can be heated and adjusted in the material conveying space 204 from the external temperature adjusting portion (the external tank 201, the cover portion 202), and the external temperature of the resin material can be equalized similarly to the internal temperature.
The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the claims.
For example, in the present embodiment, the fluid is temperature-adjusting water, but is not limited thereto. The structures of the screw, the flow path, the external temperature adjusting portion, and the like are not limited to those of the screw 10, the inflow side flow path 121, the outflow side flow path 131, the external groove 201, the cover portion 202, and the like in the present embodiment.
