[0002] The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable to daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. Existing rubber gaskets are generally produced by vulcanization molding. During production, the rubber strip is generally placed on the top of the lower mold of the vulcanizer, and then pressed, heated and vulcanized by the upper mold.

The demoulding ejector rod is provided on the vulcanizer to push the rubber product to separate from the lower mold, and an air jet mechanism is provided on the demoulding ejector rod.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figure 1-Figure 7 As shown, an automatic unloading device for a rubber molding vulcanizing machine proposed in one embodiment of the present application includes:

[0036] The fixed plate 1 is horizontal after installation, and two mounting plates 2 are installed on the top of the fixed plate 1. The two mounting plates 2 are vertically connected to the fixed plate 1. The two mounting plates 2 are located at both ends of one side of the fixed plate 1. The tops of the two mounting plates 2 are hinged with movable plates 3. The movable plates 3 rotate on the top of the fixed plate 1 with their own hinge axes as the center. It should be specifically stated that a collection box for collecting rubber workpieces can be placed on one side of the fixed plate 1 close to the axis of the movable plate 3;

[0037] A rotating rod 4 is rotatably mounted on the two mounting plates 2. The rotating rod 4 is located below the movable plate 3. A first gear 5 is mounted on the rotating rod 4. The first gear 5 is located between the two mounting plates 2. A second gear 6 is mounted on the hinge axis of the movable plate 3 and meshes with the first gear 5. When the movable plate 3 rotates along its hinge axis, it can be driven to rotate by the first gear 5 and the second gear 6 meshing with each other;

[0038] A plurality of through grooves 7, in the present application, the number of through grooves 7 is preferably two, which are spaced apart and distributed on the top of the movable plate 3. The through grooves 7 are strip-shaped, and the spacing between adjacent through grooves 7 is consistent with their groove spacing, and there are plug blocks 8 slidingly matched therein, and the plug blocks 8 slide in the vertical direction of the through grooves 7. The movable plate 3 and the plug blocks 8 are matched to form a mold groove 9 on the top, and the movable plate 3 and the plug blocks 8 are matched to form a lower mold. When the fixed plate 1 and the movable plate 3 are parallel to each other, and the movable plate 3 and the plug blocks 8 are coplanar, the rubber strip can be placed on the mold groove 9, and then, the existing The vulcanization upper mold is pressed, heated and vulcanized to form a rubber workpiece. A first transmission mechanism 10 is installed at the bottom of the movable plate 3, which is linked with the rotating rod 4. After the vulcanization process is completed, the movable plate 3 can be turned over to drive the rotating rod 4 to rotate. The first transmission mechanism 10 can drive multiple plug blocks 8 to slide synchronously. At this time, the multiple plug blocks 8 can slide in a direction away from the top of the movable plate 3, so that the rubber workpiece can be separated from the plug blocks 8, thereby reducing the contact area between the rubber workpiece and the mold, facilitating its demoulding and falling into the collection box;

[0039] The box body 11 is arranged at the bottom of the fixed plate 1, and a piston plate 12 is slidably matched therein. The piston plate 12 is fitted with the inner wall of the box body 11. A second transmission mechanism 13 is arranged on the piston plate 12, which is linked with the rotating rod 4. When the movable plate 3 is flipped in the direction away from the fixed plate 1, the rotating rod 4 rotates forward, and the piston plate 12 can be driven to slide in the box body 11 through the second transmission mechanism 13. A one-way air intake valve 14 is installed on one side of the box body 11. At this time, the piston plate 12 can slide toward the one-way air intake valve 14. A flow channel 15 is constructed in the movable plate 3, which is connected to the box body 11 through a hose 16. It is on the same side as the hose 16, and multiple channels are distributed on the flow channel 15. There is an air jet hole 17, and the air jet hole 17 is arranged at the top of the flow channel 15. When the piston plate 12 slides, the air in the box body 11 can pass through the hose 16, the flow channel 15 and the air jet hole 17 in sequence. At this time, the gas can enter the gap between the rubber workpiece and the movable plate 3, and then the rubber workpiece can be blown away from the movable plate 3 while being cooled by the gas, so that it can fall into the collection box. When the movable plate 3 turns toward the fixed plate 1 and is parallel to the fixed plate 1, the rotating rod 4 is reversed, and the piston plate 12 is driven by the second transmission mechanism 13 to slide in the box body 11 in the direction away from the one-way air intake valve 14, and the outside air can enter the box body 11 at this time;

[0040] A driving mechanism 18, which is disposed at the bottom of the fixed plate 1 and is used to drive the movable plate 3 to rotate along the hinge point;

[0041] After the rubber strip is vulcanized and molded on the top of the movable plate 3 and the plug block 8, the movable plate 3 parallel to the fixed plate 1 can be driven to flip along the hinge axis by the driving mechanism 18, and the rotating rod 4 can be driven to rotate clockwise by the first gear 5 and the second gear 6 that are meshed with each other, and then the multiple plug blocks 8 and the piston plate 12 can be driven to slide by the first transmission mechanism 10 and the second transmission mechanism 13 respectively, so that the multiple plug blocks 8 can be separated from the rubber workpiece, and the piston plate 12 can slide toward the one-way air intake valve 14, so that the contact area between the rubber workpiece and the mold can be reduced while the gas in the box body 11 can be removed from the mold through the piston plate 12. The multiple jet holes 17 at the top of the flow channel 15 eject gas, and when the gas fills the gap between the rubber workpiece and the movable plate 3, that is, cools it, it can also blow the rubber workpiece away from the movable plate 3 close to the collection box, so that it can fall into the collection box, thereby completing the automatic unloading operation. Then, the fixed plate 1 can be driven to flip in the opposite direction along the hinge axis by the driving mechanism 18. At this time, the rotating rod 4 can be driven to rotate in the opposite direction, and then the multiple plug blocks 8 can be driven to slide toward the top of the movable plate 3 by the first transmission mechanism 10, and the piston plate 12 can be driven to slide in the direction away from the one-way air intake valve 14 by the second transmission mechanism 13 to reset;

[0042] The present application adopts the design of a rotating rod 4. When the movable plate 3 rotates along the hinge point, the first transmission mechanism 10 and the second transmission mechanism 13 can respectively drive multiple plug blocks 8 and the piston plate 12 to slide, so that the multiple plug blocks 8 can be separated from the rubber workpiece, and the piston plate 12 can slide toward the one-way air intake valve 14. In this way, the contact area between the rubber workpiece and the mold can be reduced, and the gas in the box body 11 can be squeezed out from the multiple jet holes 17 at the top of the flow channel 15 through the piston plate 12. When the gas fills the gap between the rubber workpiece and the movable plate 3, it can cool the gas and blow the rubber workpiece away from the movable plate 3 close to the collection box so that it falls into the collection box, thereby completing the automatic unloading operation. Compared with the prior art, it has the advantage of strong linkage, which can simplify the structure of the unloading device, reduce production costs, and make it easier to operate.

[0043] like Figure 3 , Figure 6 and Figure 7As shown, in some embodiments, the first transmission mechanism 10 includes a connecting plate 1001 that is slidably matched with the bottom of the movable plate 3, and a plurality of plug blocks 8 are connected to the top of the connecting plate 1001. When the connecting plate 1001 slides, it can drive the plurality of plug blocks 8 to slide. A first rack 1002 is vertically connected to one side of the connecting plate 1001. A driving gear 1003 is rotatably installed at the bottom of the movable plate 3, which meshes with the first rack 1002. When the driving gear 1003 rotates clockwise, the first rack 1002 can be driven to drive the connecting plate 1001 to slide in a direction away from the top of the movable plate 3. A first sprocket 1004 is coaxially connected to the driving gear 1003, and a rotating rod 4 is fixedly installed on the side thereof. A second sprocket 1005 is installed, and a third sprocket 1006 is rotatably installed on the hinge shaft of the movable plate 3, which is connected to the first sprocket 1004 through a first chain 1007, and a fourth sprocket 1008 is coaxially connected to the third sprocket 1006, and the fourth sprocket 1008 is connected to the third sprocket 1006, and is connected to the second sprocket 1005 through a second chain 1009. When the rotating rod 4 rotates clockwise under the action of the movable plate 3, the fourth sprocket 1008 can be driven to rotate clockwise through the second sprocket 1005 and the second chain 1009, and at the same time, the first sprocket 1004 can be driven to rotate clockwise through the third sprocket 1006 and the first chain 1007.

[0044] like Figure 1 and Figure 4 As shown, in some embodiments, a U-shaped frame 19 is connected to the bottom of the movable plate 3, and the connecting plate 1001 is slidably installed on the inner side of the U-shaped frame 19. When the movable plate 3 and the fixed plate 1 are parallel to each other, and the bottom of the U-shaped frame 19 is in contact with and overlaps the top of the fixed plate 1, the U-shaped frame 19 can protect the first rack 1002 on the one hand, so that it is not easy to collide with the fixed plate 1 and be damaged. On the other hand, the movable plate 3 can be protected, so that it is not easy to bend and be damaged when the vulcanization mold is pressed.

[0045] like Figure 1 , Figure 3 and Figure 6As shown, in some embodiments, the second transmission mechanism 13 includes a connecting column 1301 constructed on the piston plate 12, the connecting column 1301 is located on the side of the piston plate 12 away from the one-way air intake valve 14, the connecting column 1301 slides through the box body 11, and a second rack 1302 is slidably matched on the outer side of the fixed plate 1, which is connected to the connecting column 1301. When the second rack 1302 slides, the piston plate 12 can be driven to slide through the connecting column 1301. The end of the rotating rod 4 is connected to the third gear 1303, and a small gear 1304 is rotatably installed on the fixed plate 1, on which a large gear 1305 is coaxially connected. The number of teeth on gear 1304 is smaller than that on large gear 1305, and small gear 1304 and large gear 1305 are respectively meshed with third gear 1303 and second rack 1302. It should be specifically noted here that the number of teeth on third gear 1303 is larger than that on small gear 1304, and small gear 1304 can be driven to rotate faster, so that when movable plate 3 drives rotating rod 4 to flip, third gear 1303 can drive small gear 1304 to rotate counterclockwise for several circles, so that large gear 1305 can drive second rack 1302 to drive connecting column 1301 and piston plate 12 to slide in the direction away from one-way intake valve 14.

[0046] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, there are two second transmission mechanisms 13, which are symmetrically arranged on opposite sides of the fixed plate 1. This design allows the piston plate 12 to slide more smoothly in the box body 11, which can effectively reduce the wear between the two, thereby increasing their service life.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a plurality of jet holes 17 are evenly distributed on the relative inner walls of a plurality of through grooves 7, and the air outlets of the jet holes 17 are close to the top of the movable plate 3. With such a design, during the vulcanization process, the movable plate 3 and the plug block 8 are coplanar, and the plug block 8 can block the jet holes 17 at this time, so that the jet holes 17 are not easily blocked by the rubber. When the movable plate 3 rotates and the plug block 8 is separated from the rubber workpiece, the air outlet of the jet hole 17 can be exposed, and then the rubber workpiece can be separated from the movable plate 3 by airflow.

[0048] like Figure 3 and Figure 6As shown, in some embodiments, the driving mechanism 18 includes a screw rod 1801 rotatably mounted at the bottom of the fixed plate 1, the axis of the screw rod 1801 is perpendicular to the hinge axis of the movable plate 3, one end of the screw rod 1801 is connected to a motor 1802, the motor 1802 is mounted at the bottom of the fixed plate 1, and is located outside the box 11 and between the two connecting columns 1301, one end of the fixed plate 1 is connected to two guide rods 1803, the guide rods 1803 and the screw rod 1801 are parallel to each other, a driving plate 1804 is slidably fitted thereon, and the driving plate 1804 is threadedly fitted with the screw rod 1801, and when the motor 1802 is working, the screw rod 1803 can be used to move the movable plate 3. 01 drives the driving plate 1804 to slide on the guide rod 1803, and the top of the driving plate 1804 is symmetrically hinged with two hinged plates 1805, the hinged parts of the hinged plates 1805 and the driving plate 1804 are far away from the fixed plate 1, and the ends of the two hinged plates 1805 are hinged to the bottom of the movable plate 3, and the ends of the hinged plates 1805 are close to the hinge axis of the movable plate 3. When the driving plate 1804 moves toward the fixed plate 1, the movable plate 3 can be pushed to flip along its own hinge axis under the action of the hinged plates 1805. When the driving plate 1804 is away from the fixed plate 1, the movable plate 3 can flip in the opposite direction to be parallel to the fixed plate 1.

[0049] like Figure 3-Figure 5 As shown, in some embodiments, a valve mechanism 20 is installed on the hose 16, and the valve mechanism 20 can limit the discharge of gas in the box 11 when the piston plate 12 moves toward the one-way air intake valve 14, so that the gas in the box 11 can be compressed. After the movable plate 3 is rotated to be close to the collection box, the valve mechanism 20 can be opened. Under the action of pressure, the gas is quickly ejected through the injection hole 17, thereby improving the demolding efficiency of the rubber workpiece and the movable plate 3.

[0050] like Figure 3-Figure 5As shown, in some embodiments, the valve mechanism 20 includes a first vertical groove 2001 and a second vertical groove 2002, which are arranged in a staggered state in the U-shaped frame 19, the first vertical groove 2001 and the second vertical groove 2002 are staggered up and down, and the opposite ends of the two are respectively connected to the flow channel 15 and the hose 16, a transverse groove 2003 is opened in the U-shaped frame 19, the opposite ends of the first vertical groove 2001 and the second vertical groove 2002 are connected to the transverse groove 2003, the first vertical groove 2001 and the second vertical groove 2002 are connected through the transverse groove 2003, and the connecting openings are paved with sealing pads 2004, the sealing pads 2004 are silicone pads, and the transverse grooves A blocking column 2005 is slidably matched in 2003. When the blocking column 2005 contacts the sealing gasket 2004, the connection between the first vertical groove 2001 and the second vertical groove 2002 can be disconnected. A through hole 2006 is obliquely opened on the top of the blocking column 2005. When the two ends of the through hole 2006 are respectively opposite to the connecting openings of the first vertical groove 2001 and the second vertical groove 2002, the first vertical groove 2001 is connected to the second vertical groove 2002. A cylinder 2007 is connected to the end of the blocking column 2005. The end of the cylinder 2007 slides through the U-shaped frame 19, and an annular plate 2008 is constructed thereon.

The end of the cylinder 2007 is connected to the arc surface 201 11 movable interference, the arc center of the arc surface 20111 is located on the axis of the rotating rod 4, when the movable plate 3 is parallel to the fixed plate 1, the end of the cylinder 2007 is in conflict with the arc surface 20111, when the movable plate 3 rotates along its own hinge axis, the end of the cylinder 2007 can slide on the arc surface 20111, and after the movable plate 3 is close to the collection box, the end of the cylinder 2007 contacts the inclined surface 20112, at this time, under the interference of the inclined surface 20112, the cylinder 2007 can drive the blocking column 2005 to slide toward the inside of the horizontal groove 2003, and at this time the first vertical groove 2001 and the second vertical groove 2002 can be connected through the through hole 2006.

[0051] like Figure 4 and Figure 5 As shown, in some embodiments, a ball 20071 is rotatably installed at the end of the cylinder 2007, which rolls and overlaps with the arc surface 20111. By adopting the design of the ball 20071, the sliding wear between the cylinder 2007 and the block 2010 can be effectively reduced, thereby extending the service life of the device.

[0052] The present invention also includes the following automatic control method:

[0053] 1. After the vulcanization molding process is completed;

[0054] When the rubber strip is vulcanized and molded on the top of the movable plate 3 and the plug block 8, the sensor detects a signal indicating that the vulcanization is completed and transmits the signal to the PLC controller.

[0055] The PLC controller instructs the driving mechanism 18 to drive the movable plate 3 to flip along the hinge axis so that it is parallel to the fixed plate 1, ready for the unloading operation.

[0056] 2. driving the rotating rod;

[0057] During the turning process of the movable plate 3, the first gear 5 and the second gear 6 mesh with each other, driving the rotating rod 4 to rotate clockwise. The PLC controller monitors the angle of the rotating rod 4 through the encoder to ensure accurate control.

[0058] The rotation of the rotating rod 4 is driven by a servo motor, and the movement of the servo motor is controlled by a PLC to ensure that the rotation process is smooth and accurate.

[0059] 3. The insert and the piston plate slide;

[0060] The PLC controller instructs the first transmission mechanism 10 to drive the plurality of inserting blocks 8 to slide along the guide rails, so that the inserting blocks 8 are gradually separated from the rubber workpiece.

[0061] At the same time, the PLC controller instructs the second transmission mechanism 13 to drive the piston plate 12 to slide toward the one-way intake valve 14. The second transmission mechanism 13 includes a connecting rod device connected between the piston plate 12 and the rotating rod 4 to ensure synchronous sliding.

[0062] 4. Jet cooling and workpiece separation;

[0063] When the piston plate 12 slides, it pushes the gas in the box body 11 to be ejected from the multiple jet holes 17 at the top of the flow channel 15. The gas ejection pressure is monitored by the air pressure sensor.

[0064] The gas fills the gap between the rubber workpiece and the movable plate 3, cools the rubber workpiece, and blows it away from the movable plate 3. The cooling process is achieved by adding a coolant in the gas flow channel, and the amount of the coolant is automatically adjusted by the coolant injection system.

[0065] Under the action of gas pressure, the rubber workpiece detaches from the movable plate 3 and falls into the collection box below. The collection box is provided with a buffer device to prevent the rubber workpiece from being damaged when it falls. The PLC controller monitors the pressure of the gas ejection through the pressure sensor to ensure that the jetting process is stable and effective.

[0066] 5. Reset the movable plate;

[0067] After the unloading operation is completed, the PLC controller instructs the driving mechanism 18 to reversely drive the movable plate 3 to flip in the opposite direction along the hinge axis so that it returns to the initial position.

[0068] The PLC controller instructs the rotating rod 4 to rotate in the opposite direction, and drives the plurality of inserting blocks 8 to slide toward the top of the movable plate 3 through the first transmission mechanism 10 to ensure that the inserting blocks 8 are reset.

[0069] At the same time, the PLC controller instructs the second transmission mechanism 13 to drive the piston plate 12 to slide in a direction away from the one-way air intake valve 14 to achieve the reset of the piston plate 12 .

[0070] Related devices and auxiliary devices include but are not limited to the following:

[0071] 1. Temperature sensors are installed inside the box 11 and at the flow channel 15 to monitor the gas temperature and ensure the cooling effect. The sensor data is transmitted to the PLC controller in real time.

[0072] The control system automatically adjusts the coolant injection amount based on the temperature sensor feedback to ensure the best cooling effect.

[0073] 2. An air pressure sensor is provided at the air jet hole 17 to monitor the air jet pressure and ensure that the air pressure is sufficient to blow the rubber workpiece away from the movable plate 3.

[0074] The sensor data is transmitted to the PLC controller in real time, and when the pressure is insufficient, the gas source output is automatically adjusted.

[0075] 3. The buffer device is installed in the collection box to buffer the impact force when the rubber workpiece falls and prevent the workpiece from being damaged. The buffer device is made of elastic material to ensure the safe fall of the workpiece.

[0076] The buffer device includes a buffer pad and a shock absorbing mechanism to ensure that the workpiece will not be damaged during the falling process.

[0077] 4. A coolant injection system is provided at the inlet of the flow channel 15 and is used to inject coolant to reduce the temperature of the ejected gas. The type and amount of the coolant are automatically adjusted by the PLC controller according to the feedback from the temperature sensor.

[0078] The coolant injection system includes a storage tank, delivery pipeline and injection valve to ensure a stable supply of coolant.

[0079] 5. The connecting rod device is connected between the rotating rod 4 and the piston plate 12, and is used to transmit the power of the rotating rod 4 to drive the piston plate 12 to slide synchronously. The connecting rod device is made of high-strength material to ensure stability and durability.

[0080] The connecting rod device is designed with an adjustment mechanism, which can adjust the sliding stroke as needed to ensure flexibility and adaptability.

[0081] 6. The control system includes: PLC controller and human-machine interface (HMI), which are used to monitor and adjust the entire vulcanization molding and unloading process. The operator sets and adjusts various parameters such as temperature, air pressure and coolant injection amount through HMI to ensure the best working condition.

[0082] The control system has data recording and fault diagnosis functions, which can record operation data in real time and automatically alarm when a fault occurs, making maintenance and troubleshooting easier.

[0083] The present invention also has the following beneficial effects:

[0084] 1. Strong linkage: The design of the rotating rod 4 enables multiple inserts 8 to slide synchronously with the piston plate 12, thereby achieving effective separation and cooling of the rubber workpiece and the mold.

[0085] 2. Automatic unloading: The rubber workpiece is cooled by gas ejection and blown off the movable plate 3, so that it automatically falls into the collection box, simplifying the unloading operation.

[0086] 3. Simplified structure: This design simplifies the structure of the feeding device, reduces production costs, and makes operation more convenient.

[0087] 4. Safe and reliable: The application of temperature sensors and air pressure sensors ensures the safety and reliability of the cooling and jetting process, reducing the risk of damage to the workpiece.
