DETAILED DESCRIPTION
[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0031] The first embodiment, as Figure 1The resin feeding and discharging device shown includes: a resin silo 100 , a resin feeding mechanism 200 , a resin discharging mechanism 300 and a buffer return channel 400 .
[0032] The resin feeding mechanism 200 is disposed in the resin silo 100 , the resin discharging mechanism 300 is disposed at the end of the resin silo 100 , one end of the buffer return channel 400 is disposed on one side of the resin discharging mechanism 300 , and the other end thereof is communicated with the resin silo 100 .
[0033] One end of the resin feeding mechanism 200 extends to one side of the resin discharging mechanism 300 , and is used to transport the resin in the resin silo 100 to the resin discharging mechanism 300 .
[0034] The resin discharge mechanism 300 is used to arrange the resin at a certain angle.
[0035] The buffer return channel 400 includes a plurality of baffles, which are arranged in a stepped structure.
[0036] Regarding the buffer return channel 400, as Figure 2 The buffer return channel 400 shown includes: a first baffle 401, a second baffle 402 and a third baffle 403 arranged in sequence from top to bottom. The first baffle 401, the second baffle 402 and the third baffle 403 are inclined plates that form a predetermined angle with the horizontal plane.
[0037] As shown in the figure, the first baffle 401 forms an angle of about 60° with the horizontal plane, and the second baffle 402 forms an angle of about 45° with the horizontal plane.
[0038] The inclined plate can reduce the resin retention in the buffer return channel 400 .
[0039] Regarding the discharge mechanism, Figure 1 and 2 The discharge mechanism shown includes: a guide bracket 301 , a motor 302 , a synchronous belt mechanism 303 , a stopper 304 and a sensor 305 .
[0040] The guide bracket 301 is installed at the end of the resin silo 100, the motor 302, the synchronous belt mechanism 303, the block 304 and the sensor 305 are installed on the guide bracket 301, the synchronous belt mechanism 303 is connected to the motor 302, the block 304 and the sensor 305 are arranged above the synchronous belt mechanism 303, the buffer return channel 400 is arranged on one side of the synchronous belt mechanism 303, and the buffer return channel 400 is located below the block 304 and the sensor 305.
[0041] like Figure 1 The motor 302 and the synchronous belt mechanism 303 are installed above the resin silo 100 through a bracket.
[0042] Regarding the resin feeding mechanism 200, Figure 3 and 4 The resin feeding mechanism 200 shown includes: a power assembly 201, a base plate 202, a push plate 203 and a fixed plate 204. The push plate 300 is directly mounted on the base plate 200 by screws, which greatly simplifies the structure, reduces the volume and the difficulty of installation.
[0043] The power assembly 201 and the fixing plate 204 are installed on the resin silo 100 , the push plate 203 is connected to the bottom plate 202 , the push plate 203 and / or the bottom plate 202 are connected to the power assembly 201 , and the push plate 203 and the fixing plate 204 are obliquely arranged in the resin silo 100 .
[0044] The push plates 203 and the fixed plates 204 are staggered and matched, and the top height positions of the plurality of fixed plates 204 and the push plates 203 are arranged in a stepped structure.
[0045] The power assembly 201 is used to drive the push plate 203 to perform reciprocating linear motion, wherein the power assembly 201 is a cylinder, or a hydraulic cylinder, or a combination of a screw mechanism and a motor 302 , or a combination of a gear rack mechanism and a motor 302 .
[0046] When the power assembly 201 drives the push plate 203 to move to the lowest position, the height position of the top end of the push plate 203 is less than or equal to the height position of the top end of the adjacent fixing plate 204 .
[0047] When the power assembly 201 drives the push plate 203 to move to the highest position, the height position of the top end of the push plate 203 is greater than or equal to the height position of the top end of the adjacent fixed plate 204 .
[0048] All push plates 203 are fixed together by the bottom plate 202. When the power component 201 drives the bottom plate 202 or one of the push plates 203 to move, all the push plates 203 move together and cooperate with all the fixed plates 204, which greatly simplifies the structure of the resin feeding mechanism 200, reduces the volume of the resin feeding mechanism 200, solves the problem of the large overall volume of the existing resin feeding mechanism 200, reduces the distance between the resin discharge mechanism 300 and the bottom of the resin silo 100, and further reduces the deformation rate of the resin.
[0049] Moreover, since the fixed plate 204 is always stationary, the drop rate of the resin on the top of the fixed plate 204 is reduced, thereby improving the resin feeding efficiency.
[0050] In this embodiment, the bottom plate 202 is as follows Figure 3 and 4 The stepped structure, or base plate 202, is shown as a flat plate disposed at an angle.
[0051] The length of the push plate 203 can be reduced by using the stepped bottom plate 202 or the obliquely arranged bottom plate 202 .
[0052] In this embodiment, the resin feeding mechanism 200 includes: a first fixed plate 204, a second fixed plate 204 and a first push plate 203, and the first push plate 203 is arranged between the first fixed plate 204 and the second fixed plate 204. Figure 3 The top end height position of the first fixing plate 204 is shown to be smaller than the bottom end height position of the second fixing plate 204 .
[0053] When the power assembly 201 drives the first push plate 203 to move to the lowest position, the top height position of the first push plate 203 is between the top height position of the first fixing plate 204 and the bottom height position of the second fixing plate 204 .
[0054] The top height of the first fixed plate 204 is smaller than the bottom height of the second fixed plate 204 , so that the push plate 203 between the first fixed plate 204 and the second fixed plate 204 is always held between the two fixed plates 204 , further ensuring the working stability of the resin feeding mechanism 200 .
[0055] Working principle: First, the power assembly 201 of the resin feeding mechanism 200 drives the push plate 203 to move to the lowest position, and the top height position of the push plate 203 is less than or equal to the top height position of the upper adjacent fixed plate 204. Figure 3 The top height of the push plate 203 is smaller than the top height of the upper adjacent fixed plate 204 , so that the resin on the upper fixed plate 204 falls onto the push plate 203 due to gravity.
[0056] When the power assembly 201 drives the push plate 203 to move to the highest position, the top height position of the push plate 203 is greater than or equal to the top height position of the next adjacent fixed plate 204. Figure 4 The top height of the push plate 203 is greater than the top height of the adjacent fixing plate 204 of the next stage, so that the resin on the push plate 203 falls on the push plate 203 due to gravity.
[0057] Repeat the above steps to move the resin in the resin silo 100 layer by layer to the top resin discharge mechanism 300 position, and then the resin discharge mechanism 300 transports the resin from the end close to the resin feeding mechanism 200 to the end close to the buffer return channel 400. In this process, the resin is arranged at a certain angle. The resin that does not meet the angle requirement is blocked by the block 304 of the resin discharge mechanism 300 and returned to the buffer return channel 400, so that the resin falls into the resin silo 100 after being buffered by several baffles of the buffer return channel 400.
[0058] In the second embodiment, the structures of the resin silo 100 , the resin feeding mechanism 200 and the resin discharging mechanism 300 are changed on the basis of the first embodiment.
[0059] In this embodiment, the resin silo 100, the resin loading mechanism 200 and the resin discharging mechanism 300 constitute a vibration plate.
[0060] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
