[0020] Wherein, the feed channel is connected with the feed port through the feed inlet channel; the adjusting core column is slidably connected in the feed channel and the feed inlet channel along the vertical direction.

[0021] Exemplarily, the aperture of the feed channel gradually decreases from the lower end of the feed channel to the feed port.

[0038] Please also read Figures 1 to 3The rapid prototyping equipment for plastic products provided by the present invention is now described. The rapid prototyping equipment for plastic products comprises a support table 1, a melting device 3, a material storage box 6, a material feeding assembly 4 and an adjusting core column 5; a molding device 2 is arranged on the top surface of the support table 1; the melting device 3 is arranged on the support table 1 and is connected to the molding device 2; a material feed port 31 is arranged on the top of the melting device 3; the material storage box 6 is placed above the material feed port 31 and is connected to the support table 1; the material feeding assembly 4 is placed between the melting device 3 and the material storage box 6 and is connected to the support table 1; a material feeding channel 411 extending in the vertical direction is arranged in the material feeding assembly 4, and the material feeding channel 411 The upper and lower ends are connected with the storage box 6 and the feed port 31 respectively; the adjusting core column 5 is slidably arranged in the feed channel 411 along the vertical direction; an adjusting block 51 is arranged on the adjusting core column 5, and the adjusting block 51 has a resting state of sliding upward to block the feed channel 411, and also has a feeding state of sliding downward to have a discharge gap with the feed channel 411; wherein, when the adjusting block 51 is in the resting state, the lower end of the adjusting core column 5 is placed above the feed port 31; when the adjusting block 51 is in the feeding state, the lower end of the adjusting core column 5 slides downward into the feed port 31.

[0039] It should be noted that the melting device 3 used in the present application can melt the transported plastic particles, and the molding device 2 can injection mold the melted liquid plastic; and the specific structures of the melting device 3 and the molding device 2 belong to the prior art and will not be repeated here.

[0040] Specifically, a connecting frame is provided on the support platform 1, wherein the feeding assembly 4 and the material storage box 6 are fixed on the support platform 1 through the connecting frame; further, the material storage box 6 and the feeding assembly 4, as well as the melting device 3 are provided between the molding device 2 and the connecting frame to facilitate material transfer and transportation. Optionally, the side of the melting device 3 away from the feeding port 31 is connected to the feeding end of the molding device 2.

[0041] It should be noted that when the adjusting block 51 is in a rest state, the material gradually accumulates at the top of the adjusting block 51. When the adjusting block 51 slides downward to a feeding state, the material is transported downward to a position close to the feed port 31. At this time, the lower end of the adjusting core column 5 penetrates into the feed port 31 to divert any clogged material. Moreover, after the adjusting core column 5 slides upward to a rest state again, the material can enter the melting device 3 through the channel diverted by the adjusting core column 5.

[0042] It should be understood that by intermittently sliding the adjusting core column 5 into the feed port 31 , the feed port 31 can be intermittently dredged to avoid the occurrence of blockage of the feed port 31 .

[0043] Compared with the prior art, the plastic product rapid prototyping equipment provided by the present invention is characterized in that the plastic particles in the storage box 6 are transported to the melting device 3 for melting through the feeding component 4, and then enter the molding device 2 for injection molding; since the feeding component 4 is provided with an adjusting core column 5 and an adjusting block 51, the adjusting core column 5 can be used to drive the adjusting block 51 to slide up and down in the feeding channel 411, so that the adjusting block 51 can be switched between a rest state and a feeding state, and, in the feeding state, the lower end of the adjusting core column extends into the feed port 31, so that the plastic particles accumulated in the feed port 31 can be diverted to avoid clogging the feed port 31, thereby ensuring the smooth transportation of the plastic particle material, saving maintenance and diversion time, and ensuring the injection molding processing speed and processing efficiency.

[0044] As a specific implementation of the above-mentioned feed channel 411 and the adjusting block 51, a first inlet for material to enter is arranged at the upper end of the feed channel 411, and the adjusting block 51 is blocked at the first inlet. When the adjusting core column 5 drives the adjusting column to move upward, the adjusting block 51 moves away from the first inlet, so that the first inlet is exposed to the material, so that the material enters the feed channel 411 from the first inlet; at this time, the discharge gap is equivalent to the first inlet.

[0045] Optionally, a telescopic cylinder is provided at the upper end of the adjusting stem 5, and the telescopic cylinder is used to drive the adjusting stem 5 and the adjusting block 51 to move up and down, thereby realizing the switching of the adjusting block 51 between the rest state and the feeding state. Optionally, the telescopic cylinder is set to be timed to extend and retract, so that the lower end of the adjusting stem 5 intermittently slides into the feeding port 31 for dredging.

[0046] See also Figure 2 In some possible embodiments, the feed channel 411 includes a first feed hole 4111 and a second feed hole 4112 which are connected in sequence from top to bottom, and the aperture of the second feed hole 4112 is larger than the aperture of the first feed hole 4111; the adjustment block 51 is a conical block whose radial dimension gradually increases from top to bottom, and the conical block slides in the vertical direction and is arranged at the step surface where the first feed hole 4111 and the second feed hole 4112 communicate; wherein, when the outer peripheral surface of the conical block is connected to the step surface, the adjustment block 51 is in a rest state, and when the conical block slides downward to form an annular gap between the outer peripheral surface and the step surface, the adjustment block 51 is in a feeding state.

[0047] It should be noted that the annular gap is the above-mentioned discharge gap.

[0048] Specifically, when the outer circumferential surface of the conical block is in contact with the step surface, the adjusting block 51 blocks the feeding channel 411, and the material cannot be transported downward, entering a stop state; when the conical block slides downward to form an annular gap between the outer circumferential surface and the step surface, the material can be transported downward from the annular gap, entering a feeding state.

[0049] It should be understood that when the adjusting block 51 is in a rest state, the conical block is sealed at the step surface, and the first batch of materials gradually accumulates on the top of the conical block, and when the accumulated mass reaches a preset value, the conical block is pressed to slide downward, thereby forming an annular gap between the outer peripheral surface of the conical block and the step surface, so that the accumulated first batch of materials can be transported downward from the annular gap to near the feed port 31. At this time, the lower end of the adjusting core column 5 penetrates into the feed port 31 to guide the materials that may be blocked, and after the adjusting core column 5 drives the conical block to slide upward until the annular gap is closed, the adjusting block 51 is in a rest state again. At this time, the second batch of materials accumulates on the top surface of the conical block again, and the first batch of materials falling from the annular gap can enter the melting device 3 through the channel guided by the adjusting core column 5.

[0050] It should be noted that the lower end of the adjusting core column 5 can slide up and down at the feed port 31, and the radial dimension of the feed port 31 is larger than the radial dimension of the adjusting core column 5. When the feed port 31 is not blocked, even if the adjusting core column 5 slides into the feed port 31, the material can still enter the melting device 3 through the annular gap between the lower end of the adjusting core column 5 and the feed port 31.

[0051] See also Figure 2 As a specific installation method of the adjusting core column 5, the upper end of the adjusting core column 5 passes through the feeding assembly 4 and is connected to the bottom of the storage box 6; the bottom of the storage box 6 is provided with a first sliding hole 61 arranged along the vertical direction, and a first elastic member 62 is fixed to the bottom of the first sliding hole 61, and the lower end of the first elastic member 62 is fixed to the upper end of the adjusting core column 5.

[0052] By setting the first elastic member 62, after the first batch of materials accumulated on the adjusting block 51 falls down, the first elastic member 62 can drive the adjusting core column 5 to reset, so that the second batch of materials can be accumulated on the adjusting block 51 on the one hand; on the other hand, the lower end of the adjusting core column 5 can make way for the feed port 31 to expand the feed area.

[0053] Specifically, a through hole suitable for adjusting the upward and downward sliding of the core column 5 is provided on the top of the material feeding assembly 4, and the lower end of the through hole is connected with the first material feeding hole 4111 so as to allow the upper end of the adjusting core column 5 to pass through.

[0054] As another specific installation method of the adjusting core column 5 , a second sliding hole arranged along the vertical direction is provided on the top of the feeding component 4 , a second elastic member is fixed to the bottom of the second sliding hole, and the lower end of the second elastic member is fixed to the upper end of the adjusting core column 5 .

[0055] Similarly, by providing a second elastic member, the second elastic member can drive the adjusting stem 5 and the adjusting block 51 to return to the rest state.

[0056] Optionally, a feed inlet of the feed assembly 4 is provided above the first feed hole 4111 , and the feed inlet is placed on one radial side of the adjusting core column 5 ; optionally, a plurality of feed inlets are provided, and are distributed at intervals along the circumference of the adjusting core column 5 .

[0057] See also Figure 2 In some possible embodiments, the feeding assembly 4 includes a first feeding barrel 41 and a second feeding barrel 42; the first feeding barrel 41 is arranged below the storage box 6; a feeding channel 411 is provided in the first feeding barrel 41; the second feeding barrel 42 is placed between the first feeding barrel 41 and the feeding port 31; a feeding channel 421 extending in the vertical direction is provided inside the second feeding barrel 42; wherein the feeding channel 411 is connected to the feeding port 31 through the feeding channel 421; the adjusting core column 5 is slidably connected in the feeding channel 411 and the feeding channel 421 along the vertical direction.

[0058] A feeding channel 411 composed of a first feeding hole 4111 and a second feeding hole 4112 is provided in the first feeding barrel 41 . A feeding channel 421 is provided below the feeding channel 411 to guide the material so that the material enters the feeding port 31 through the feeding channel 421 .

[0059] See also Figure 2 , illustratively, the aperture of the feed channel 421 gradually decreases from the lower end of the feed channel 411 to the feed port 31 .

[0060] Specifically, the feed channel 421 includes an upper channel, a middle channel and a lower channel, wherein the upper channel has an aperture equal to that of the second feed hole 4112, the middle channel is a conical structure with decreasing radial dimensions, and the lower channel has a structure equal to the aperture of the feed port 31, so that the material can transition in the feed channel 421 and be transported to the feed port 31.

[0061] See also Figure 2 In some embodiments, the upper and lower ends of the second feed barrel 42 are rotatably connected to the bottom of the first feed barrel 41 and the top of the melting device 3 respectively; a plurality of groups of stirring rods 422 are arranged at intervals on the inner wall of the feed channel 421, and one end of the stirring rod 422 extends toward the adjusting core column 5.

[0062] By rotating the second feed barrel 42 so that there is relative rotation between the second feed barrel 42 and the feed port 31, the possibility of material adhering to the feed channel 421 is reduced; further, by setting a stirring rod 422 to stir the material and transport it downward to the feed port 31, material adhesion is avoided.

[0063] See also Figure 3In some embodiments, the plastic product rapid prototyping equipment also includes a driving motor 71, a driving wheel 72 and a driven wheel 73; the driving motor 71 is arranged on the support platform 1 and is placed on one side of the melting device 3; the driving wheel 72 is arranged at the power output end of the driving motor 71; the driven wheel 73 is sleeved and fixed on the outer side of the second feed barrel 42, and is meshed with the driving wheel 72 for transmission.

[0064] Specifically, the driving wheel 72 and the driven wheel 73 are mutually meshing gear sets; the power output end of the drive motor 71 extends upward to the lower section of the second feed barrel 42, and the driven wheel 73 is arranged on the lower section of the second feed barrel 42, so that the driving wheel 72 and the driven wheel 73 are meshed for transmission; the drive motor 71 drives the second feed barrel 42 to rotate through the mutually meshing driving wheel 72 and the driven wheel 73, so that the stirring rod 422 in the feeding channel 421 stirs the material, thereby reducing material adhesion.

[0065] See also Figure 3 Exemplarily, a containing box 7 is arranged between the feeding assembly 4 and the melting device 3, and a driving motor 71, a driving wheel 72, a driven wheel 73, and a second feeding barrel 42 are arranged in the containing box 7, and one end of the second feeding barrel 42 extends upward out of the containing box 7 and is rotatably connected to the lower end of the first feeding barrel 41.

[0066] By providing the accommodating box 7 , the driving motor 71 , the driving wheel 72 and the driven wheel 73 are covered in the accommodating box 7 , so as to prevent external dust from entering and causing wear of the driving wheel 72 and the driven wheel 73 .

[0067] See also Figure 2 In some possible embodiments, a discharge port 63 communicating with the feeding channel 411 is provided at the bottom of the storage box 6 , and the bottom wall of the storage box 6 is inclined and extended toward the discharge port 63 .

[0068] By extending the bottom of the material storage box 6 obliquely to the discharge port 63 , it is convenient for the material in the material storage box 6 to enter the material conveying channel 411 from the discharge port 63 .

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
