[0041] Example 1

[0042] like Figure 1 and 2 As shown, a fully automatic stamping forming machine is pre-set with a feeding station, a stamping station and a discharging station, including:

[0043] The turntable mechanism 300 includes a multi-station turntable 310 and a rotary drive assembly 320. Multiple lower forming molds 330 are evenly spaced on the same circumference of the multi-station turntable 310. The rotary drive assembly 320 is connected to and drives the multi-station turntable 310 to rotate, so that the rotation of the multi-station turntable 310 sequentially moves each lower forming mold 330 to a respective station.

[0044] A feeding mechanism 400 is located at the feeding station and is used to inject raw materials into the lower forming mold 330 moved to the feeding station;

[0045] A stamping mechanism 500 is located at the stamping station and is used to stamp the raw material in the forming lower die 330 moved to the stamping station;

[0046] The discharge mechanism 600 is located at the discharge station and is used to take out the molded product in the lower molding die 330 that has moved to the discharge station.

[0047] The fully automatic stamping and forming machine drives the multi-station turntable 310 to rotate, and moves the various forming lower molds 330 located on the multi-station turntable 310 to the feeding station, stamping station and discharging station in sequence, so as to automatically complete the steps of raw material feeding, stamping and forming, and finished product discharging at the feeding station, stamping station and discharging station through the feeding mechanism 400, stamping mechanism 500 and discharging mechanism 600 respectively. It can be used for fully automatic stamping and forming of bath salts or other powder products, and greatly improves the efficiency of stamping and forming.

[0048] The fully automatic stamping machine includes the following steps when working:

[0049] The turntable mechanism 300 moves one of the lower forming molds 330 to the feeding station by rotating the multi-station turntable 310;

[0050] The feeding mechanism 400 injects raw materials into the lower forming mold 330 moved to the feeding station;

[0051] The turntable mechanism 300 moves the lower forming die 330 injected with raw materials to the stamping station by rotating the multi-station turntable 310;

[0052] The stamping mechanism 500 stamps and forms the raw material in the lower forming die 330 moved to the stamping station;

[0053] The turntable mechanism 300 moves the stamped lower die 330 to the discharge station by rotating the multi-station turntable 310;

[0054] The discharging mechanism 600 takes out the molded product in the lower molding die 330 which is moved to the discharging station;

[0055] Repeat the above steps.

[0056] Preferably, the number of forming lower molds 330 on the multi-station turntable 310 is consistent with the preset number of stations of the fully automatic stamping and forming machine, and one forming lower mold 330 corresponds to one station, so that the multi-station turntable 310 rotates and moves the previous forming lower mold 330 to the next station while rotating and moving the next forming lower mold 330 to the previous station. For example, the multi-station turntable 310 moves the previous forming lower mold 330 from the stamping station to the discharging station while moving the next forming lower mold 330 from the feeding station to the stamping station.

[0057] like Figure 3As shown, the rotation drive assembly 320 includes a first drive shaft 321, a second drive shaft 322 and a third drive shaft 323. The first drive shaft 321 is parallel to the second drive shaft 322 and is connected to the second drive shaft 322 through a first transmission assembly 326. The third drive shaft 323 is perpendicular to the first drive shaft 321 and the second drive shaft 322 and is connected to the second drive shaft 322 through a second transmission assembly. The third drive shaft 323 is perpendicular to the multi-station turntable 310 and is fixedly connected to the center of the multi-station turntable 310.

[0058] The power output by the first drive shaft 321 is transmitted to the second drive shaft 322 through the first transmission assembly 326, and then the second drive shaft 322 transmits the power to the third drive shaft 323 through the second transmission assembly (not shown in the figure), and finally the third drive shaft 323 drives the multi-station turntable 310 to rotate.

[0059] In this embodiment, the first drive shaft 321 is the output shaft of the servo motor 324, the second drive shaft 322 and the third drive shaft 323 are the input shaft and output shaft of the cam divider 325 respectively; the first transmission assembly 326 is a belt transmission assembly, and the second transmission assembly is a gear transmission assembly.

[0060] like Figure 4 As shown, the lower molding die 330 includes a fixing portion 331 and a molding portion 332. The fixing portion 331 is arranged on the periphery of the molding portion 332 for being installed and fixed with the multi-station turntable 310. A molding channel 334 extending vertically to the top is provided in the molding portion 332, and the cross-section of the molding channel 334 is the same at all locations along the vertical direction.

[0061] The same cross-section of the forming channel 334 at all locations along the vertical direction mentioned here means that the shape and size of the cross-section of the forming channel 334 at all locations along the vertical direction are the same.

[0062] like Figure 2 As shown, the stamping mechanism 500 is located above the multi-station turntable 310 at the stamping station, and includes a stamping upper die 510 and a stamping lifting assembly 520. The cross-section of the stamping upper die 510 is adapted to the cross-section of the forming channel 334 in the forming lower die 330. The stamping lifting assembly 520 is connected to drive the stamping upper die 510 to rise and fall so that the stamping upper die 510 enters or leaves the forming channel 334 of the forming lower die 330; when the stamping upper die 510 enters the forming channel 334 of the forming lower die 330, the raw material in the forming channel 334 is stamped and formed.

[0063] During stamping, the stamping lifting assembly 520 drives the stamping upper die 510 to descend so that the stamping upper die 510 enters the molding channel 334 of the molding lower die 330, and the stamping upper die 510 is pressed on the raw material located in the molding lower die 330, and then cooperates with the molding lower die 330 to press the raw material into shape, wherein the lower surface pressed by the stamping upper die 510 and the bottom surface and channel wall of the molding channel 334 together enclose a molding cavity for the raw material; after the stamping is completed, the stamping lifting assembly 520 drives the stamping upper die 510 to rise so that the stamping upper die 510 leaves the molding channel 334 of the molding lower die 330.

[0064] The cross-section of the stamping upper die 510 mentioned here is adapted to the cross-section of the molding channel 334 in the molding lower die 330, which means that the cross-sectional shape of the stamping upper die 510 is the same as the cross-sectional shape of the molding channel 334, and the cross-sectional size of the stamping upper die 510 is slightly smaller than the cross-sectional size of the molding channel 334, so that after the stamping upper die 510 enters the molding channel 334, it can fit tightly with the molding channel 334, but will not produce too much friction with the channel wall of the molding channel 334.

[0065] The stamping lifting assembly 520 includes a fixed frame 521, a lifting frame 522 and a stamping driver 523, the stamping driver 523 is arranged on the fixed frame 521, and the stamping upper die 510 is arranged on the lifting frame 522; the fixed frame 521 and the lifting frame 522 are arranged relative to each other in an upper and lower direction, and a plurality of sliding sleeves 524 surrounding the stamping driver 523 are provided on the fixed frame 521, and the lifting frame 522 is movably connected to the fixed frame 521 through a plurality of sliding shafts 525 inserted into the corresponding sliding sleeves 524; the output shaft of the stamping driver 523 is connected to drive the lifting frame 522 to rise and fall relative to the fixed frame 521, and then the stamping upper die 510 is driven to rise and fall through the lifting of the lifting frame 522.

[0066] In this embodiment, the punching driver 523 may be, but is not limited to, a cylinder.

[0067] like Figure 4 and 5 As shown, the lower molding die 330 also includes a support portion 333 and a support plate 335. The cross-section of the support plate 335 is adapted to the cross-section of the molding channel 334, and can be raised and lowered in the molding channel 334 of the molding portion 332. The support portion 333 is arranged at the bottom of the molding portion 332, and is used to support the support plate 335 in the molding channel 334, and is provided with a top outlet 336 connected to the molding channel 334.

[0068] During stamping, the support plate 335 serves as the bottom of the forming channel 334 , and the lower surface of the stamping upper die 510 , the upper surface of the support plate 335 and the channel wall of the forming channel 334 together enclose a forming cavity for the raw material.

[0069] The cross-section of the support plate 335 mentioned here is adapted to the cross-section of the forming channel 334, which means that the cross-sectional shape of the support plate 335 is the same as the cross-sectional shape of the forming channel 334, and the cross-sectional size of the support plate 335 is slightly smaller than the cross-sectional size of the forming channel 334, so that the support plate 335 can fit tightly with the forming channel 334 in the forming channel 334, but will not generate too much friction with the channel wall of the forming channel 334.

[0070] like Figure 2 As shown, the discharge mechanism 600 is located below the multi-station turntable 310 at the discharge station, and includes an ejector pin 610 and an ejector lifting assembly 620. The ejector lifting assembly 620 is connected to drive the ejector pin 610 to rise and fall, so that the ejector pin 610 enters or leaves the molding channel 334 of the molding lower mold 330 through the ejection outlet 336; when the ejector pin 610 enters the molding channel 334 of the molding lower mold 330, it lifts the support plate 335 in the molding channel 334.

[0071] During discharge, the ejector lifting assembly 620 drives the ejector pin 610 to rise, so that the ejector pin 610 enters the molding channel 334 of the molding lower mold 330 through the ejection outlet 336. The ejector pin 610 first presses against the support plate 335 in the molding channel 334, and then pushes the support plate 335 upward to rise in the molding channel 334. The lifting of the support plate 335 drives the molded product on the support plate 335 to leave the molding channel 334 and rise to the desired position. The molded product on the lower mold 330 is then removed manually by a production worker, or automatically by a robot. After the molded product is removed, the ejector lifting assembly 620 drives the ejector pin 610 to descend, so that the ejector pin 610 leaves the molding channel 334 of the lower mold 330 through the ejection outlet 336, and the support plate 335 in the molding channel 334 automatically descends and returns to the support portion 333 under the action of its own gravity.

[0072] The ejection lifting assembly 620 includes an ejection driver, and the ejector pin 610 is connected to the output shaft of the ejection driver. In this embodiment, the ejection driver can be, but is not limited to, a cylinder.

[0073] like Figure 6 and 7As shown, the feeding mechanism 400 includes:

[0074] A feed silo 410 is provided with a feed port 411 at the bottom thereof;

[0075] The screw shaft 420 and the rotating shaft 430 are vertically arranged in the silo 410. The lower end of the screw shaft 420 extends into the feed port 411 of the silo 410, and the upper end is coaxially connected to the lower end of the rotating shaft 430. The upper end of the rotating shaft 430 extends to the outside of the top of the silo 410.

[0076] The feeding drive assembly 440 is disposed outside the silo 410 and is connected to drive the rotating shaft 430 to rotate, so that the rotation of the rotating shaft 430 drives the screw shaft 420 to rotate simultaneously.

[0077] During feeding, the feeding drive assembly 440 drives the rotating shaft 430 to rotate, so as to drive the spiral shaft 420 to rotate simultaneously through the rotating shaft 430. When the spiral shaft 420 rotates, the spiral blades on its outer periphery drive the raw material in the silo 410 to move forward, so as to discharge the raw material in the silo 410 from the feeding port 411 and inject it into the molding channel 334 of the molding lower mold 330 moved to the feeding station.

[0078] The feeding drive assembly 440 includes a feeding drive 441 , and the feeding drive 441 is in transmission connection with the rotating shaft 430 via a third transmission assembly 442 .

[0079] In this embodiment, the feeding driver 441 can be but is not limited to a stepper motor. The stepper motor is a motor driven by a pulse signal. One pulse signal corresponds to a predetermined angular displacement or linear displacement. By presetting the amount of pulse signals required for each drive of the stepper motor, the feeding amount of the screw shaft 420 each time can be accurately controlled; the third transmission component 442 is a belt transmission component.

[0080] The silo 410 includes an upper silo 413 and a lower silo 414 that are connected to each other. The diameter of the storage cavity of the upper silo 413 is constant, and the diameter of the storage cavity of the lower silo 414 gradually decreases from top to bottom. The feeding port 411 is opened at the bottom of the lower silo 414.

[0081] A feeding baffle 412 is provided at the feeding port 411 at the bottom of the silo 410. Figure 9 As shown, the feeding baffle 412 includes multiple blocking areas 4121 and multiple opening areas 4122, and the multiple blocking areas 4121 and multiple opening areas 4122 are spaced apart in sequence around the spiral shaft 420 on the feeding baffle 412, and the width of each opening area 4122 gradually increases from the center to the periphery.

[0082] During feeding, when the spiral shaft 420 rotates to discharge the raw materials in the silo 410 from the feeding port 411, the blocking area 4121 on the feeding baffle 412 forms a blockage for the raw materials at the feeding port 411, which increases the pressure of the raw materials at the feeding port 411 to a certain extent. On the one hand, the moisture in the raw materials can be squeezed out to prevent the raw materials from being affected by moisture and affecting subsequent stamping and forming. On the other hand, the raw materials that have agglomerated due to moisture can be crushed to prevent the agglomerated raw materials from affecting the accuracy of the feeding amount.

[0083] The ratio of the blocking area 4121 to the opening area 4122 on the feeding baffle 412 may vary according to the different raw materials. In order to facilitate the replacement of the feeding baffle 412, it is preferred that Figure 8 As shown, the lower material bin 414 includes a first bin portion 4141 and a second bin portion 4142 arranged opposite to each other on the left and right sides, and a first storage trough 4143 and a first discharge trough 4144 are provided on the side of the first bin portion 4141 facing the second bin portion 4142, and the first discharge trough 4144 is connected to the bottom of the first storage trough 4143, and the first discharge trough 4144 is provided with a first clamping groove 4147; the second bin portion 4142 is provided with a second storage trough 4145 and a second discharge trough 4146 on the side facing the first bin portion 4141, and the second discharge trough 4146 is connected to the bottom of the second storage trough 4145, and the second discharge trough 4146 is provided with a second clamping groove 4148; the first bin portion 41 One side of 41 is rotatably connected to one side of the second bin part 4142, and the other side of the first bin part 4141 is detachably connected to the other side of the second bin part 4142, and the first bin part 4141 and the second bin part 4142 can be relatively closed and opened through the rotatable connection and the detachable connection; when the first bin part 4141 and the second bin part 4142 are relatively closed, the first storage trough 4143 and the second storage trough 4145 together constitute the storage cavity of the lower bin 414, the first discharge trough 4144 and the second discharge trough 4146 together constitute the discharge port of the lower bin 414, and the first clamping groove 4147 and the second clamping groove 4148 together constitute the clamping limit groove for installing the feeding baffle 412; Figure 9 As shown, the feed baffle 412 extends a cylindrical portion 4123 in the axial direction, and is provided with a clamping boss 4124 surrounding the outer periphery of the cylindrical portion 4123 and cooperating with the clamping limiting groove.

[0084] When replacing the feeding baffle 412, first disassemble the detachable end between the first bin portion 4141 and the second bin portion 4142 through the detachable connection, then rotate the second bin portion 4142 relative to the first bin portion 4141 to open the first bin portion 4141 and the second bin portion 4142, then remove the old feeding baffle 412, and insert one side of the snap-fitting boss 4124 of the new feeding baffle 412 into the first snap-fitting groove 4147 of the first bin portion 4141 or the second bin portion 4142. One of the second snap-fit ​​grooves 4148, and then the second bin part 4142 is rotated relative to the first bin part 4141 to cover the first bin part 4141 and the second bin part 4142, so that the other side of the snap-fit ​​protrusion 4124 of the new feeding baffle 412 is embedded in the first snap-fit ​​groove 4147 of the first bin part 4141 or the other of the second snap-fit ​​groove 4148 of the second bin part 4142, and finally the detachable end between the first bin part 4141 and the second bin part 4142 is connected through the detachable connection.

[0085] The detachable connection between the first compartment 4141 and the second compartment 4142 may be, but is not limited to, a block connection, a screw connection, or the like.

[0086] In order to prevent the raw materials in the silo 410 from agglomerating due to moisture and to ensure that the various components in the raw materials are fully mixed, Figure 6 and 7 As shown, the feeding mechanism 400 further includes:

[0087] A rotating sleeve 450 is vertically disposed in the silo 410 and sleeved outside the rotating shaft 430 , rotatable relative to the rotating shaft 430 , with its upper end extending outside the top of the silo 410 ;

[0089] The stirring drive assembly 470 is disposed outside the silo 410 and is connected to drive the rotating sleeve 450 to rotate, so that the rotation of the rotating sleeve 450 drives the stirring arms 460a and 460b to rotate simultaneously.

[0090] During stirring, the stirring drive assembly 470 drives the rotating sleeve 450 to rotate, so as to drive the stirring arms 460a and 460b to rotate simultaneously through the rotating sleeve 450, and the stirring arms 460a and 460b stir the raw materials in the silo 410 when rotating; since the rotating sleeve 450 can rotate relative to the rotating shaft 430, the stirring drive assembly 470 drives the stirring arms 460a and 460b to rotate without affecting the feeding of the spiral shaft 420. Similarly, when the feeding drive assembly 440 drives the spiral shaft 420 to rotate, it also does not affect the stirring of the stirring arms 460a and 460b.

[0093] Preferably, the fifth arm portion 463 b is parallel to the wall surface of the storage cavity of the lower hopper 414 .

[0094] The length of the first arm portion 461a is smaller than that of the third arm portion 461b, so that the distance between the second arm portion 462a and the spiral sleeve 450 is smaller than the distance between the fourth arm portion 462b and the spiral sleeve 450; the length of the second arm portion 462a is greater than that of the fourth arm portion 462b.

[0105] The discharging mechanism 600 takes out the molded product in the lower molding die 330 which is moved to the discharging station;

[0106] Repeat the above steps.

[0107] The support mechanism 800 is located below the multi-station turntable 310 at the stamping station, and includes a support platform 810 and a support lifting assembly 820. The support lifting assembly 820 is connected to drive the support platform 810 to rise and fall, and the support platform 810 can support the bottom of the forming lower mold 330 after being raised; the support platform 810 is raised to support the bottom of the forming lower mold 330 before the stamping mechanism 500 stamps the raw material in the forming lower mold 330.

[0108] Before stamping, the support lifting assembly 820 drives the support platform 810 to rise so that the support platform 810 supports the bottom of the forming lower mold 330, and then the stamping lifting assembly 520 drives the stamping upper mold 510 to descend so that the stamping upper mold 510 enters the forming channel 334 of the forming lower mold 330 to stamp the raw material. After the stamping is completed, the stamping lifting assembly 520 drives the stamping upper mold 510 to rise so that the stamping upper mold 510 leaves the forming channel 334 of the forming lower mold 330, and the support lifting assembly 820 drives the support platform 810 to descend.

[0109] The support lifting assembly 820 includes a support driver, and the ejector pin is connected to the output shaft of the ejector driver. In this embodiment, the support driver can be, but is not limited to, a cylinder.

[0110] In this embodiment, the support mechanism 800 is mounted and fixed on the base plate 102 .

[0111] Example 3

[0112] As an optimization solution of the first or second embodiment, in order to prevent the support plate 335 from being unable to automatically reset due to the friction between the support plate 335 and the channel wall of the forming channel 334 after being lifted up by the discharge mechanism 600, in this embodiment, Figure 1 As shown, the fully automatic stamping and forming machine is also preset with a reset station, which is located between the discharging station and the feeding station; the fully automatic stamping and forming machine also includes:

[0113] The reset mechanism 700 is located at the reset station and is used to press down and reset the support plate 335 in the lower molding die 330 that has moved to the reset station.

[0114] The fully automatic stamping machine includes the following steps when working:

[0115] The turntable mechanism 300 moves one of the lower forming molds 330 to the feeding station by rotating the multi-station turntable 310;

[0116] The feeding mechanism 400 injects raw materials into the lower forming mold 330 moved to the feeding station;

[0120] The turntable mechanism 300 moves the stamped lower die 330 to the discharge station by rotating the multi-station turntable 310;

[0121] The discharge mechanism 600 removes the molded product from the lower molding die 330 that has been moved to the discharge station. During discharge, the ejection lifting assembly 620 drives the ejector pin 610 to rise, so that the ejector pin 610 enters the molding channel 334 of the lower molding die 330 through the ejection outlet 336. The ejector pin 610 first presses against the support plate 335 in the molding channel 334, and then pushes the support plate 335 upward to rise in the molding channel 334. The rising support plate 335 drives the molded product on the support plate 335 to leave the molding channel 334 and rise above the lower molding die 330. The molded product on the lower molding die 330 is then removed manually by a production worker, or automatically by a robot.

[0122] The turntable mechanism 300 moves the lower mold 330 for removing the molded product to the reset position by rotating the multi-station turntable 310;

[0123] The reset mechanism 700 presses down and resets the support plate 335 in the lower molding die 330 that has moved to the reset station.

[0124] Repeat the above steps.

[0125] like Figure 2 As shown, the reset mechanism 700 is located above the reset station, and includes a reset pressure head 710 and a reset lifting assembly 720. The reset lifting assembly 720 is connected to drive the reset pressure head 710 to rise and fall so that the reset pressure head 710 enters or leaves the molding channel 334 of the molding lower mold 330; when the reset pressure head 710 enters the molding channel 334 of the molding lower mold 330, it presses down the support plate 335 in the molding channel 334 to reset it.

[0126] During resetting, the reset lifting assembly 720 drives the reset pressure head 710 to descend so that the reset pressure head 710 enters the molding channel 334 of the molding lower mold 330, and the reset pressure head 710 is pressed on the support plate 335 located in the molding lower mold 330, thereby pressing the support plate 335 in the molding channel 334 down and resetting it; after the reset is completed, the reset lifting assembly 720 drives the reset pressure head 710 to rise so that the reset pressure head 710 leaves the molding channel 334 of the molding lower mold 330.
