Description

Technical Field

[0001] The present application relates to the field of rubber vulcanization equipment, and in particular to a feeding system for a vulcanization bladder vulcanization furnace. Background Art

[0002] Vulcanization is an important process in the production of rubber products such as tires. Under the action of high-temperature media, the raw rubber undergoes a series of complex chemical reactions, losing the plasticity of the mixed rubber and gaining the high elasticity of cross-linked rubber, thereby obtaining excellent physical and mechanical properties, heat resistance, solvent resistance and corrosion resistance. The vulcanization bladder is a tool for tire vulcanization. Depending on the vulcanizer and fixture, the vulcanization bladder is divided into different models. The vulcanization bladder is equivalent to the inner mold of the tire mold. During the tire vulcanization process, it is mainly filled with compressed air, nitrogen or superheated water to stretch it, support the tire rubber blank and form an internal pressure vulcanized tire.

[0003] Vulcanization bladders are usually made of butyl rubber, which also needs to be vulcanized during the production process of vulcanized rubber. The vulcanization process of vulcanization bladders is usually completed in a shaping vulcanizer. The raw rubber is extruded through an extruder to form a ring of set weight, which is placed in a tray and transported to a set position on the side of the vulcanizer. The ring is then placed in the trough of the vulcanizer manually or with the help of tools for mold forming and hot pressing vulcanization.

[0004] The feeding operation of the existing curing bladder curing furnace material ring is mostly carried out manually with the help of auxiliary tools, which not only has high labor intensity and low production efficiency, but also the placement state of the raw material in the material trough is easily affected by manual operation, the quality fluctuation of the produced curing bladder is large, and the consistency of the product is poor. Recently, some mechanical devices for curing furnace feeding have also appeared, such as the Chinese utility model patent with the authorization announcement number CN210308604U, which discloses a curing machine feeding device, which uses a claw mechanism to grab the tire, and uses a rotating mechanism to drive the manipulator grabbing device to rotate to load and unload the tire. However, the device can only grab the tires transmitted separately on the conveyor belt, and a complete tire circulation and transportation line needs to be laid out, and the equipment investment is large. Moreover, the tire grabbed on the claw mechanism needs to be rotated before it can be placed in the processing station. The large-diameter rotation requires a large space, and the stability and safety are poor, and it is easy to interfere with the curing machine. Summary of the invention

[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] An embodiment of the curing bladder curing furnace feeding system of the present application is as follows Figure 1 and Figure 2 As shown, it includes a transfer device and a grabbing device. The transfer device is used to transfer the material ring from the previous process to the vulcanization furnace for vulcanization treatment; the grabbing device is used to grab the material ring at a specified position in the transfer device and put it into the material trough of the vulcanization furnace for molding and vulcanization treatment, and grab the vulcanization capsule after vulcanization treatment and place it at the specified position.

[0041] The transfer device can be a vehicle-like structure of various forms, and a running wheel is arranged at the bottom of the transfer device to facilitate the movement of the transfer device between different processing stations. The transfer device is provided with a feeding cavity 1 and a receiving cavity 2 arranged adjacent to each other, and a plurality of material trays 3 are stacked and placed in the feeding cavity 1 or the receiving cavity 2. Usually, a material ring is placed in each material tray 3. By using a plurality of stacked material trays 3, a plurality of material rings can be transported at a time by the transfer device, thereby improving the transfer efficiency of the material rings.

[0042] A loading lifting plate 11 is provided in the loading chamber 1. The loading lifting plate 11 can be slidably connected to the wall of the loading chamber 1, or supported in the loading chamber 1 by a lifting support mechanism, or suspended in the loading chamber 1 by a lifting suspension mechanism, so that the loading lifting plate 11 can move up and down in the loading chamber 1. A plurality of material trays 3 with material rings are stacked on the loading lifting plate 11, so that the plurality of material trays 3 and the material rings placed on the material trays 3 are all located in the loading chamber 1. A lifting drive mechanism 4 is provided on the transfer device, and the lifting drive mechanism 4 can drive the loading lifting plate 11 to rise and fall in the loading chamber 1. When a material tray 3 is taken out from the loading chamber 1, the lifting drive mechanism 4 drives the loading lifting plate 11 to rise a certain distance, so that the material tray 3 below rises to the original position of the removed material tray 3, and keeps the material tray 3 on the top of the loading lifting plate 11 always in the fixed position set at the opening of the loading chamber 1, thereby ensuring that the grasping device can grasp the material ring from a fixed position, thereby improving the convenience of grasping the material ring.

[0043] The grabbing device can grab the raw rubber material ring placed in the material tray 3 from the material tray 3 on the top of the upper cavity 1, put it into the material trough of the vulcanizing furnace, and after being extruded by a mold, it is heated and vulcanized in the material trough. During the vulcanization process, cross-links are formed between the raw rubber molecules to form a three-dimensional network structure to form a vulcanization capsule.

[0044] In some embodiments of the curing bladder curing furnace feeding system of the present application, as Figures 1 to 3 As shown, a lifting slide rail is vertically arranged on the wall of the loading chamber 1, and a sliding groove matched with the lifting slide rail is arranged at the corresponding position of the loading lifting plate 11. The loading lifting plate 11 is slidably connected to the wall of the loading chamber 1 through the cooperation of the sliding groove and the lifting slide rail, thereby ensuring the position stability of the loading lifting plate 11 during the lifting process.

[0045] A material receiving lifting plate 21 is arranged in the material receiving chamber 2, a lifting slide rail is vertically arranged on the wall of the material receiving chamber 2, a sliding groove matched with the lifting slide rail is arranged at the corresponding position on the material receiving lifting plate 21, and the material receiving lifting plate 21 is slidably connected to the wall of the material receiving chamber 2 through the cooperation of the sliding groove and the lifting slide rail, thereby ensuring the position stability of the material receiving lifting plate 21 during the lifting process.

[0046] The material tray 3 includes a tray surface 31 and supporting feet 32. The supporting feet 32 ​​are fixed at the corners of the bottom surface of the tray surface 31 and are used to support the tray surface 31 at a certain height, so that a certain height gap is formed between the tray surfaces 31 of the stacked material trays 3, which is used to accommodate the material rings placed on the tray surface 31 and prevent the upper layer of the tray surface 31 from squeezing the material rings on the lower layer of the tray surface 31. The bottom of the supporting feet 32 ​​arranged at the corners of the tray surface 31 is supported on the edge of the feeding lifting plate 11, the receiving lifting plate 21 or the tray surface 31 of the lower layer, and will not affect the placement of the material in the middle position.

[0047] A material grabbing avoidance groove 311 extending from the center to the peripheral area is provided in the middle part of the disk surface 31. Usually, the material grabbing avoidance groove 311 is six long rectangular through grooves, and the six material grabbing avoidance grooves 311 are evenly arranged on the disk surface 31. The material grabbing avoidance groove 311 can allow the material claws of the grabbing device to enter a position below the disk surface 31 to grab the material placed on the disk surface 31.

[0048] A foot positioning groove 312 is provided at the corner of the top surface of the disk surface 31. At the same time, a foot positioning groove 312 is also provided at the corresponding position on the loading lifting plate 11 and the receiving lifting plate 21. The foot positioning groove 312 is provided corresponding to the support foot 32, and is usually a blind groove formed by stamping on the disk surface 31, the loading lifting plate 11 or the receiving lifting plate 21. When the material tray 3 is placed on the loading lifting plate 11 or the receiving lifting plate 21, or stacked with each other, the support foot 32 of the upper material tray 3 is supported in the foot positioning groove 312 on the lower disk surface 31, the loading lifting plate 11 or the receiving lifting plate 21, so as to ensure the accurate positioning of the placement position of the material tray 3. The foot positioning groove 312 can be set to a conical shape, and accordingly, the bottom of the support foot 32 is also set to a corresponding conical shape. The conical foot positioning groove 312 can guide the support foot 32, which is conducive to the stacking of multiple material trays 3.

[0049] While driving the loading lifting plate 11 to rise and fall, the lifting drive mechanism 4 also drives the receiving lifting plate 21 to rise and fall synchronously. Moreover, under the drive of the lifting drive mechanism 4, when the loading lifting plate 11 rises, the receiving lifting plate 21 falls at the same speed; conversely, when the loading lifting plate 11 falls, the receiving lifting plate 21 rises at the same speed and rises in the opposite direction synchronously. In this way, after the material ring on the material tray 3 in the loading chamber 1 is taken out, the material tray 3 can be placed in the receiving chamber 2. As the receiving lifting plate 21 falls, a new accommodating space for placing the feeding tray 3 is formed at the opening of the receiving chamber 2, so that the material trays 3 taken out from the loading chamber 1 can be stacked in the receiving chamber 2 in sequence.

[0050] In a preferred embodiment of the curing bladder curing furnace feeding system of the present application, as Figure 2 As shown, the lifting drive mechanism 4 includes a first feeding wheel group 41, a second feeding wheel group 42, a lifting drive shaft 43, a lifting drive motor 44, a first receiving wheel group 45, a second receiving wheel group 46 and a plurality of lifting drive chains 47. The feeding chamber 1 and the receiving chamber 2 are arranged on the left and right sides of the transfer device, that is, arranged in a direction parallel to the length direction of the vulcanizing furnace; the first feeding wheel group 41 and the second feeding wheel group 42 are respectively arranged on the left and right sides of the feeding chamber 1. The first feeding wheel group 41 and the second feeding wheel group 42 each include two sprockets, and the two sprockets in each group are respectively arranged on the front and rear sides above the opening of the feeding chamber 1, that is, respectively located on the sides adjacent to the vulcanizing furnace and away from the vulcanizing furnace.

[0051] The first material receiving wheel group 45 and the second material receiving wheel group 46 are respectively arranged on the left and right sides of the material receiving chamber 2, and the first material receiving wheel group 45 and the second material receiving wheel group 46 each include two sprockets, and the two pulleys in each group are respectively arranged on the front and rear sides above the opening of the material receiving chamber 2, and the first feeding wheel group 41 and the first material receiving wheel group 45 are correspondingly arranged in the front and rear direction, and the second feeding wheel group 42 and the second material receiving wheel group 46 are correspondingly arranged in the front and rear direction, and the sprockets on the front and rear sides of the first feeding wheel group 41 and the first material receiving wheel group 45 are respectively staggered with the sprockets on the front and rear sides of the second feeding wheel group 42 and the second material receiving wheel group 46 in the front and rear direction.

[0052] The lifting drive shaft 43 is arranged between the feeding chamber 1 and the receiving chamber 2, and is arranged in the front-to-back direction. The second feeding wheel set 42 and the first receiving wheel set 45 are both arranged on the lifting drive shaft 43. There are four lifting drive chains 47, wherein the left ends of the two lifting drive chains 47 respectively cross the sprockets on the first feeding wheel set 41 to connect to the left front corner and the left rear corner of the feeding lifting plate 11, and the right ends respectively cross the sprockets on the first receiving wheel set 45 to connect to the left front corner and the left rear corner of the receiving lifting plate 21; the left ends of the two lifting drive chains 47 respectively cross the sprockets on the second feeding wheel set 42 to connect to the right front corner and the right rear corner of the feeding lifting plate 11, and the right ends respectively cross the sprockets on the second receiving wheel set 46 to connect to the right front corner and the right rear corner of the receiving lifting plate 21.

[0053] The lifting drive motor 44 is fixed on the transfer device, and its output shaft is connected to the lifting drive shaft 43. The depth of the feeding chamber 1 and the receiving chamber 2 is the same, and the length of the lifting drive chain 47 is set so that when the feeding lifting plate 11 is located at the bottom position of the feeding chamber 1, the receiving lifting plate 21 is located at the top position of the receiving chamber 2.

[0054] As a specific embodiment of the feeding system of the vulcanization capsule vulcanization furnace of the present application, a first material tray sensor for detecting the position of the top material tray 3 on the feeding lifting plate 11 is provided on the side wall of the feeding chamber 1. When the feeding lifting plate 11 rises so that the top material tray 3 above it rises to the position corresponding to the first material tray sensor, the first material tray sensor generates a trigger signal to control the lifting drive motor 44 to stop rotating, thereby ensuring that the top material tray 3 on the feeding lifting plate 11 is located at a fixed height position at the opening of the feeding chamber 1.

[0055] A material sensor for detecting the material rings on the top material tray 3 on the loading lifting plate 11 is also provided on the side wall of the loading chamber 1. When the material sensor detects that the material rings on the top material tray 3 are taken away by the grabbing device, the first material sensor generates a trigger signal to notify the removal of the material tray 3 on the top layer of the loading lifting plate 11, or controls the corresponding mechanism to move the material tray 3 on the top layer of the loading lifting plate 11, such as transferring it to the receiving lifting plate 21, or stacking it to the top layer of the material tray 3 on the receiving lifting plate 21. When the material sensor detects that a material ring is placed on the top material tray 3, the first material sensor generates a trigger signal to control the loading lifting plate 11 to descend, notifying the placement of another material tray 3 on the top layer of the loading lifting plate 11, or controlling the corresponding mechanism to place a material tray 3 on the top layer of the loading lifting plate 11, such as transferring the material tray 3 on the top layer of the receiving lifting plate 21 to the top layer of the receiving lifting plate 21.

[0056] A second material tray sensor is provided on the side wall of the material receiving chamber 2 for detecting the position of the top material tray 3 on the material receiving lifting plate 21. When the material receiving lifting plate 21 rises so that the top material tray 3 above it rises to the position corresponding to the second material tray sensor, the second material tray sensor generates a trigger signal to control the lifting drive motor 44 to stop rotating, thereby ensuring that the top material tray 3 on the material receiving lifting plate 21 is located at a fixed height at the opening of the material receiving chamber 2, and the top material tray 3 on the loading lifting plate 11 is located at a fixed height at the opening of the loading chamber 1.

[0057] In some embodiments of the curing bladder curing furnace feeding system of the present application, as Figure 2 , Figure 4 and Figure 5 As shown, the transfer device also includes a tray transfer mechanism 5, which includes a transfer slide 51, a sliding drive screw 52, ​​a telescopic lifter 53 and a lift driver 54. A slide rail mounting bar is provided on the front and rear sides of the feeding chamber 1 and the receiving chamber 2, respectively. The transfer slide 13 is horizontally arranged on the slide rail mounting bar and extends from the feeding chamber 1 to the receiving chamber 2, and the transfer slide 51 is slidably connected to the transfer slide 13. The sliding drive screw 52 is arranged between the transfer slide 13 and the transfer slide 51, and is used to drive the transfer slide 51 to slide along the transfer slide 13 between the feeding chamber 1 and the receiving chamber 2. A proximity switch can also be provided at the set position of the feeding chamber 1 and the receiving chamber 2 on the slide rail mounting bar, so that the transfer slide 51 stops at the set position of the feeding chamber 1 or the receiving chamber 2.

[0058] The telescopic lifter 53 is arranged on the transfer slide 51, and can be extended under the drive of the lift driver 54, and supported under the top material tray 3 in the upper material chamber 1, so that the top material tray 3 rises and separates from the next material tray 3, and is transferred from the upper material chamber 1 to the receiving material chamber 2 with the movement of the transfer slide 51, and is placed on the receiving material lifting plate 21, or stacked on the top layer of the material tray 3 on the receiving material lifting plate 21, so as to transfer the material tray 3 from the upper material chamber 1 to the receiving material chamber 2. Of course, similar actions can also be used to transfer the material tray 3 from the receiving material chamber 2 to the upper material chamber 1.

[0059] In a preferred embodiment of the curing bladder curing furnace feeding system of the present application, as Figures 4 to 6 As shown, the telescopic lifter 53 includes a telescopic screw 531, a telescopic lifting sleeve 532 and a lifting block 533. A lifting sleeve hole 511 is provided on the transfer slide 51, and the telescopic screw 531 is provided in the lifting sleeve hole 511. The lifting driver 54 usually uses a servo motor, and the lifting driver 54 is provided in the transfer slide 51, and can be provided at the bottom of the lifting sleeve hole 511, and the output shaft of the lifting driver 54 is connected to the telescopic screw 531. An axial slide 5111 is provided on the side wall of the lifting sleeve hole 511 adjacent to the bottom of the hole, and an axial slide groove 5321 corresponding to the axial slide is provided on the outer side wall of the telescopic lifting sleeve 532, and the telescopic lifting sleeve 532 is slidably provided in the lifting sleeve hole 511, so that the axial slide 5111 is located in the axial slide groove 5111. A lifting sleeve inner hole 5322 is provided in the middle of the outer end of the telescopic lifting sleeve 532, a polygonal clamping hole 5323 is provided in the middle of the bottom wall of the lifting sleeve inner hole 5322, a lifting sleeve threaded hole 5324 is provided coaxially at the bottom of the clamping hole 5323, and the lifting sleeve threaded hole 5324 is threadedly connected with the telescopic screw 531. The end of the telescopic screw 531 is set as a square optical axis 5311, a polygonal clamping block 534 and a conical push block 535 are sleeved on the square optical axis, the conical push block 535 has a conical surface facing the clamping block 534 and is fixedly connected with the clamping block 534, the conical push block 535 is located on the outer side of the clamping block 534, a spring retaining ring 5312 is provided at the end of the square optical axis 5311, and a clamping block spring 536 is provided between the spring retaining ring 5312 and the conical push block 535.

[0060] When the fixed lifting driver 54 rotates, the telescopic screw 531 is driven to rotate, driving the telescopic lifting sleeve 532 located at the bottom of the lifting sleeve hole 511 to slide outward, so that the telescopic lifting sleeve 532 extends out and enters the bottom of the material tray 3.

[0061] The lifting block 533 is fixedly arranged on one side of the telescopic lifting sleeve 532. When the axial slide bar 5111 is located in the axial slide groove 5111, the lifting block 533 is located at a horizontal position on one side of the telescopic lifting sleeve 532. As the telescopic lifting sleeve 532 slides outward in the lifting sleeve hole 511, the axial slide bar 5111 escapes from the axial slide groove 5111. At this time, the lifting block 533 is pressed by the material tray 3, and the telescopic lifting sleeve 532 still slides outward under the drive of the telescopic screw 531 until the clamping block 534 is clamped into the clamping hole 5323.

[0062] At this time, the telescopic lifting sleeve 532 will rotate with the rotation of the telescopic screw rod 531, and the lifting block 533 will also push the top pusher tray 3 from below with the rotation of the telescopic lifting sleeve 532, so that the support foot 32 of the tray 3 leaves the support foot positioning groove 312 on the lower tray 3 or the loading lifting plate 11. At this time, the sliding drive screw rod 52 rotates, driving the transfer slide bar 51 to move toward the receiving chamber 2, driving the tray 3 to move toward the receiving chamber 2 along with the transfer slide bar 51.

[0063] When the transfer slide bar 51 moves to the set position above the material receiving chamber 2, the sliding drive screw 52 stops rotating. At this time, the lifting driver 54 rotates in the opposite direction, and the lifting block 533 gradually rotates to the horizontal position on one side of the telescopic lifting sleeve 532. The height of the material tray 3 supported on the lifting block 533 gradually decreases, and the horizontal position also produces a certain degree of translation, so that the support foot 32 of the material tray 3 is directly opposite to the support foot positioning groove 312 on the material receiving lifting plate 21 below or the material tray 3 on the top thereof, and the material tray 3 is placed on the material receiving lifting plate 21 or the material tray 3 on the top thereof, so that the support foot 32 is supported in the support foot positioning groove 312 below.

[0064] A push rod hole 5331 extending toward the inner hole 5322 of the lifting sleeve is provided on the outer side of the lifting block 533. A conical push rod 537 is slidably provided in the push rod hole 5331. One end of the conical push rod 537 passes through the side wall of the telescopic lifting sleeve 532 and abuts against the conical surface of the conical pushing block 535. The other end of the conical push rod 537 extends out of the end of the lifting block 533 and is fixedly connected to the side push rod 538. When the lifting block 533 is located in a horizontal position laterally of the telescopic lifting sleeve 532, the side push rod 538 extends downward from the end of the conical push rod 537. A push rod inclined surface 5381 is provided on the outer side of the lower end of the side push rod 538. A lifting block stop rod 12 is provided on the side wall of the feeding chamber 1 and the receiving chamber 2 on one side of the lifting block 533. A thrust slope corresponding to the push rod slope 5381 is provided at the position where the lifting block stop rod 12 is opposite to the side push rod 538. When the lifting block 533 rotates to a nearly horizontal state, the push rod slope 5381 on the side push rod 538 contacts the thrust slope on the lifting block stop rod 12, pushing the side push rod 538 and the conical push rod 537 to slide toward the inner hole 5322 of the lifting sleeve. The conical push rod 537 squeezes the conical surface of the conical push block 535 so that the conical push block 535 moves on the square optical axis 5311 in a direction away from the clamping hole 5323, driving the clamping block 534 to leave the clamping hole 5323. At this time, the telescopic lifting sleeve 532 no longer rotates with the telescopic screw 531. The rotation of the telescopic screw 531 drives the telescopic lifting sleeve 532 to slide into the lifting sleeve hole 511. The axial sliding groove 5321 on the telescopic lifting sleeve 532 engages with the axial sliding bar 5111 on the lifting sleeve hole 511, and the telescopic lifting sleeve 532 further slides into the lifting sleeve hole 511, so that the telescopic lifting sleeve 532 retracts to the outside of the range of the material trough 3 without affecting the up and down movement of the material tray 3.

[0065] After the telescopic lifting sleeve 532 is retracted, the sliding drive screw 52 rotates in the opposite direction, driving the transfer slide bar 51 to move in the opposite direction back to the set position above the loading chamber 1, preparing to transfer the next material tray 3.

[0066] A positioning baffle is provided on the bottom surface of the side of the vulcanizing furnace to limit the parking position of the transfer device and ensure the consistency of the parking positions of different transfer devices on the side of the vulcanizing furnace. A power socket is provided on the positioning baffle, and a power plug is provided at the corresponding position on the transfer device. When the transfer device is parked at the set position, the power plug on the transfer device is inserted into the power socket on the positioning baffle to supply power to the transfer device.

[0067] In some embodiments of the curing bladder curing furnace feeding system of the present application, as Figures 7 to 9As shown, the grabbing device includes a grabbing installation mechanism 6, a lifting and translation mechanism 7 and a material grabbing mechanism 8. The grabbing installation mechanism 6 is arranged on one side of the vulcanizing furnace, and is used to install and fix the lifting and translation mechanism 7 and the material grabbing mechanism 8, and locate the position of the material grabbing mechanism 8; the lifting and translation mechanism 7 is arranged between the grabbing installation mechanism 6 and the material grabbing mechanism 8, so that the material grabbing mechanism 8 can be lifted and translated relative to the grabbing installation mechanism 6, so that the material grabbing mechanism 8 can move to a suitable position, grab the material ring on the transfer device and transfer it to the material trough of the vulcanizing furnace, or grab the vulcanized capsule after vulcanization processing in the material trough of the middle vulcanizing furnace.

[0068] The material grabbing mechanism 8 includes a base connecting rod 81, a gripper base 82, a rotation driving plate 83, a rotation driving motor 84 and a plurality of material grippers 85. The base connecting rod 81 is fixedly connected to the lifting and translation mechanism 7, so that it can perform lifting and / or translational motion under the drive of the lifting and translation mechanism 7. Usually, the upper end of the base connecting rod 81 is fixed to the lifting and translation mechanism 7, and the gripper base 82 is fixed to the lower end of the base connecting rod 81.

[0069] A plurality of gripper grooves 821 are dispersedly arranged on the gripper substrate 82. Usually, the plurality of gripper grooves 821 are evenly arranged on the gripper substrate 82 on a circle with the center of the gripper substrate 82 as the center. The rotation drive plate 83 is arranged above the gripper substrate 82 and is rotationally connected to the gripper substrate 82. The rotation drive motor 84 is fixed on the gripper substrate 82, or can be fixed on the substrate connecting rod 81. The rotation drive motor 84 is drivingly connected to the rotation drive plate 83, so that the rotation drive plate 83 can rotate on the gripper substrate 82 under the drive of the rotation drive motor 84. A plurality of rotation drive grooves 831 are arranged on the rotation drive plate 83. The number of the plurality of rotation drive grooves 831 is the same as the number of the gripper grooves 821, and the positions thereof also correspond to the positions of the gripper grooves 821. The rotation drive grooves 831 are usually arranged in an involute shape. As the rotation drive plate 83 rotates, the gripper grooves 821 and the rotation drive grooves 831 intersect each other at different radial positions.

[0070] The material gripper 85 includes a gripper mounting rod 851 and an outer support gripper 852. The top of the gripper mounting rod 851 is slidably mounted in the gripper slide groove 821, so that it can slide radially in the gripper slide groove 821. A driving rod 8511 is arranged on the top of the gripper mounting rod 851, and the driving rod 8511 is inserted into the rotation driving groove 831. When the rotation driving plate 83 rotates, a radial driving force can be applied to the driving rods 8511 on multiple material grippers 85 at the same time through multiple rotation driving grooves 831, so as to drive the gripper mounting rods 851 of multiple material grippers 85 to synchronously slide radially on the gripper base plate 82.

[0071] The external support gripper 852 is fixed on the outside of the gripper mounting rod 851. When the multiple material grippers 85 are driven by the rotary drive motor 84 to move synchronously to the outside of the gripper base plate 82, the multiple external support grippers 852 are synchronously moved to the outside and supported in the inner hole of the material ring or the vulcanization capsule, so that the material ring or the vulcanization capsule is supported on the multiple external support grippers 852 at the same time, and the material gripper 85 completes the grasping of the material ring or the vulcanization capsule. When the multiple material grippers 85 are driven by the rotary drive motor 84 to move synchronously to the inside of the gripper base plate 82, the multiple external support grippers 852 are synchronously moved inward, leaving the inner wall of the material ring or the vulcanization capsule, and putting the material ring or the vulcanization capsule down from the material gripper 85.

[0072] In a preferred embodiment of the curing bladder curing furnace feeding system of the present application, as Fig. 9 As shown, the gripper mounting rod 851 includes a vertical mounting rod 8512, a horizontal mounting rod 8513 and a gripper stopper 8514. The horizontal mounting rod 8513 is fixed to the lower end of the vertical mounting rod 8512, and supports the outer support gripper 852 at a distance from one end outside the vertical mounting rod 8512, so that multiple outer support grippers 852 can grab materials that are larger than the diameter of the gripper base plate 82, reducing the possible interference between the gripper base plate 82 and the materials. The gripper stopper 8514 is fixed to the outer end of the upper side of the horizontal mounting rod 8513.

[0073] The external support gripper 852 includes a gripper side rod 8521 and a gripper foot 8522. The lower part of the gripper side rod 8521 is rotatably connected to the outer end of the horizontal mounting rod 8513, and a blocking structure is provided below the outer end of the horizontal mounting rod 8513, so that the gripper side rod 8521 can only rotate from the vertical position to the upper end toward the inner side. The gripper foot 8522 is fixed to the outer side of the bottom of the gripper side rod 8521. When the horizontal mounting rod 8513 pushes the gripper side rod 8521 to move outward, so that the gripper side rod 8521 contacts the inner side of the material, if the volume of the material is large, the material will contact the upper position of the gripper side rod 8521, pushing the upper end of the gripper side rod 8521 inward, and the lower end and the gripper foot 8522 to rotate outward, so that the gripper foot 8522 can extend into the outer position below the material, thereby supporting the bottom of the material and improving the stability of the grasped material.

[0074] As the gripper side rod 8521 rotates, the upper part of the gripper side rod 8521 conflicts with the gripper limit block 8514, limiting the rotation angle of the gripper side rod 8521, ensuring the support of the gripper side rod 8521 on the inner side of the material, limiting the radial movement of the material on the outer support gripper 852, and ensuring the stability of the gripped material.

[0075] In some embodiments of the curing bladder curing furnace feeding system of the present application, as Figure 7 and Fig.10 As shown, the lifting and translation mechanism 7 includes a telescopic lifting rod 71, a lifting rod bottom plate 72, a lateral slide plate 73 and a gripper slide seat 74. One end of the telescopic lifting rod 71 is fixedly connected to the gripping and mounting mechanism 6, and the other end is fixed to the middle of the top surface of the lifting rod bottom plate 72, so that the lifting rod bottom plate 72 is fixed at a set height below the gripping and mounting mechanism 6, and the fixed height of the lifting rod bottom plate 72 can be adjusted. The telescopic lifting rod 71 can use various suitable commercial hydraulic lifting rods, electric lifting rods, etc.

[0076] A pair of slide rails are provided on the upper and lower sides of the lateral slide 73, and the lifting rod bottom plate 72 and the gripper slide seat 74 are respectively slidably connected to the slide rails on the upper and lower sides of the lateral slide 73, so that they can slide along the slide rails on the lateral slide 73. The lifting rod bottom plate 72 slides on the lateral slide 73, so that the lateral slide 73 slides toward the material trough of the vulcanizing furnace, or slides toward the material loading chamber 1 of the transfer device; the gripper slide seat 74 slides on the lateral slide 73, so that the gripper slide seat 74 slides toward the end of the lateral slide 73 where the material trough is located, or slides toward the end of the material loading chamber 1 of the lateral slide 73. A bottom plate screw rod 731, a slide screw rod 732 and a screw driving motor 733 are arranged on the lateral slide 73. The bottom plate screw rod 731 and the slide screw rod 732 are arranged parallel to the upper and lower sides of the lateral slide 73 along the length direction of the lateral slide 73, and are rotatably connected to the lateral slide 73. The lifting rod bottom plate 72 and the gripper slide 74 are fixedly connected to the sliders on the bottom plate screw rod 731 and the slide screw rod 732 respectively. A linkage gear 734 is fixedly arranged at the relative position of one end of the bottom plate screw rod 731 and the slide screw rod 732. The two linkage bearings 734 have the same size and number of teeth and are meshed with each other. The screw driving motor 733 is fixed on the lateral slide 73, and its output shaft is interconnected with any one of the bottom plate screw rod 731 and the slide screw rod 732.

[0077] By rotating the screw drive motor 733, the bottom plate screw 731 and the slide screw 732 can be driven to rotate synchronously in opposite directions, and the lifting rod bottom plate 72 and the gripper slide 74 can be driven to slide in opposite directions on the upper and lower sides of the lateral slide 73. When the lifting rod bottom plate 72 slides on the lateral slide 73 toward the end where the vulcanizing furnace is located, since the lifting rod bottom plate 72 is fixed on the telescopic lifting rod 71 and cannot move laterally, the actual effect is that the lateral slide 73 slides on the lifting rod bottom plate 72 toward the upper material chamber 1. At this time, the gripper slide 74 also slides synchronously on the lateral slide 73 toward the upper material chamber 1, which increases the moving speed and moving distance of the gripper slide 74.

[0078] When the vulcanizing furnace is loaded with materials, the screw drive motor 733 rotates to drive the lateral slide plate 73 to slide toward the upper material chamber 1. When the lifting rod bottom plate 72 moves to the end of the lateral slide plate 73 where the vulcanizing furnace is located, the gripper slide 74 also moves to the end of the lateral slide plate 73 where the upper material chamber 1 is located, so that the material gripper 85 is located directly above the material tray 3 in the upper material chamber 1. The telescopic lifting rod 71 is extended to make the material gripper 85 drop to a height equivalent to the material on the material tray. When the rotating drive motor 84 drives multiple material grippers 85 to move outward synchronously, multiple external support grippers 852 support the inner side of the material ring, so as to conveniently grab the material ring on the material tray 3. At this time, the telescopic lifting rod 71 shrinks, and the material gripper 85 rises to lift the material. The screw drive motor 733 rotates in the opposite direction to drive the lateral slide plate 73 to slide toward the material trough of the vulcanizing furnace, and the gripper slide 74 also moves synchronously to the end of the lateral slide plate 73 where the material trough is located, so that the material gripper 85 is located directly above the material trough of the vulcanizing furnace. The telescopic lifting rod 71 is extended to make the material gripper 85 drop to a suitable height, and the rotary drive motor 84 is driven to drive multiple material grippers 85 to move inward synchronously, so that the material ring on the material gripper 85 is placed in a fixed position in the material trough of the vulcanizing furnace.

[0079] In a preferred embodiment of the curing bladder curing furnace feeding system of the present application, as Figure 7 As shown, the grabbing and mounting mechanism 6 includes a track bracket 61, a grabbing and mounting track 62, a grabbing mechanism mounting seat 63 and a mounting seat driving motor 64. The track bracket 61 is fixed to one side of the vulcanizing furnace, and the grabbing and mounting track 62 is fixed to the track bracket 61, and usually extends to the processing station of the next process of the vulcanization process of the vulcanizing bladder. The grabbing mechanism mounting seat 63 is slidably mounted on the grabbing and mounting track 62, and the mounting seat driving motor 64 is fixed to the grabbing mechanism mounting seat 63 and can drive the grabbing mechanism mounting seat 63 to slide along the grabbing and mounting track 62. The upper end of the telescopic lifting rod 71 is fixed to the grabbing mechanism mounting seat 63, so that the lifting and translation mechanism 7 and the material grabbing mechanism 8 move together with the grabbing mechanism mounting seat 63.

[0080] After the vulcanization of the vulcanization capsule in the trough of the vulcanization furnace is completed, the material gripper 85 grabs the vulcanization capsule in the trough of the vulcanization furnace, and the mounting seat driving motor 64 drives the grabbing mechanism mounting seat 63 together with the vulcanization capsule on the material gripper 85 to move along the grabbing mounting track 62 to the next processing step, and the vulcanization capsule is placed on the next station for processing in the next step. The mounting seat driving motor 64 drives the grabbing mechanism mounting seat 63 back to the set position on the side of the vulcanization furnace, grabs the material ring from the upper material chamber 1 and puts it into the trough of the vulcanization furnace for molding and vulcanization.
