Description

Technical Field

[0001] This application relates to the field of golf ball core processing equipment, and in particular to an automatic loading and unloading device for a vulcanizing machine. Background Technology

[0002] In the manufacturing process of golf balls, the molding quality of the core directly determines the overall performance of the ball, such as elasticity, flight trajectory, and durability. The vulcanization process, as the core step in golf ball core preparation, primarily functions to subject the rubber strip raw material to a cross-linking reaction within a vulcanizing machine under specific temperature, pressure, and time conditions, thereby forming a core blank or finished core with stable physical properties.

[0003] Currently, the industry generally uses traditional vulcanizing machines for the vulcanization of golf ball cores. During core processing, operators first place the cut rubber strips one by one into the mold cavity of the vulcanizing machine. After loading, the machine is started for vulcanization. Once vulcanization is complete, the mold opens, and the operator manually removes the formed core from the mold, completing the unloading process, before proceeding to the next production cycle.

[0004] Manual loading and unloading in production is not only inefficient, but also suffers from poor consistency and accuracy, as well as high labor intensity and safety hazards. With the continuous growth of the golf ball market and the trend towards automation and intelligence in manufacturing, traditional manual loading and unloading has become a key bottleneck restricting the improvement of vulcanizing machine production efficiency and product quality stability. Therefore, developing a device that can automatically load and unload vulcanizing machines to replace manual operation, improve production efficiency, ensure product quality stability, and reduce labor intensity and safety risks has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] In order to replace the traditional manual feeding and unloading of belts, improve production efficiency, ensure product quality stability, and reduce labor intensity and safety risks, this application provides an automatic feeding and unloading device for a vulcanizing machine.

[0006] The automatic loading and unloading device for a vulcanizing machine provided in this application adopts the following technical solution: An automatic loading and unloading device for a vulcanizing machine includes a support frame mounted on one side of the vulcanizing machine. A loading box is mounted on the support frame. A positioning plate is fixedly connected inside the loading box. Multiple loading cylinders are mounted inside the positioning plate. The loading cylinders are vertically oriented and open at both ends. Multiple elastic arc-shaped baffles are mounted at the bottom of the loading cylinders. The arc-shaped baffles are evenly spaced along the circumference of the loading cylinders. The tops of the arc-shaped baffles are hinged to the bottoms of the loading cylinders, and the bottoms of the arc-shaped baffles are free ends. The width of the arc-shaped baffles decreases sequentially from top to bottom. The bottom of the baffle forms a closed receiving cavity. The positioning plate is equipped with a drive assembly that drives the arc-shaped baffle to slide outward to expand and open the receiving cavity or to contract inward to close the receiving cavity. The side wall of the feeding cylinder is equipped with a venting ring with a venting hole communicating with the inside of the feeding cylinder. The venting ring is connected to an exhaust assembly. The lower mold of the vulcanizing machine is equipped with a ejector mechanism, which is used to lift the ball core to achieve demolding. The support is equipped with a drive mechanism that drives the feeding box to reciprocate between the mold and the support of the vulcanizing machine.

[0007] By adopting the above technical solution, when using the equipment, the user adds a rubber strip to the feeding cylinder. The bottom of the rubber strip is located in the receiving cavity formed by the arc-shaped baffle. The drive mechanism drives the feeding box to move between the molds. After the feeding box slides above the lower mold, the drive component drives the arc-shaped baffle to flip outward, causing the arc-shaped plate to expand outward. The rubber strip automatically falls from between the arc-shaped baffles into the cavity of the lower mold, completing the automatic feeding. When the rubber strip forms a ball core on the vulcanizing machine, the drive component drives the arc-shaped baffle to expand outward, and the ejector mechanism lifts the ball, causing the ball core to be demolded from the lower mold. The exhaust component works, creating a negative pressure state inside the feeding cylinder, which adsorbs the processed ball core into the receiving cavity. The drive component drives the arc-shaped baffle to contract and close the bottom of the feeding cylinder, thereby automatically removing the processed ball core. This replaces the traditional manual feeding and unloading, improving production efficiency, ensuring product quality stability, and reducing labor intensity and safety risks.

[0008] Optionally, the drive assembly includes multiple positioning rods fixedly connected to the positioning plate. The bottom of the positioning rods is hinged to an arc-shaped baffle. A pull rod is fixedly connected to the arc-shaped baffle. A connecting ring is provided outside the feeding cylinder. The connecting ring is located outside the arc-shaped plate. A rotating shaft is rotatably connected to the end of the pull rod away from the arc-shaped baffle. A sliding groove is opened at the bottom of the connecting ring, and the rotating shaft is slidably connected to the sliding groove. A drive cylinder is fixedly connected to the top of the positioning plate. Multiple drive cylinders are configured. The drive cylinders are vertically arranged. The piston rod of the drive cylinder is upward and the end is fixedly connected to a connecting rod. A connecting column is fixedly connected to the bottom of the connecting rod. The axial direction of the connecting column is vertical. The connecting column passes through the positioning plate and is fixedly connected to the connecting ring.

[0009] By adopting the above technical solution, when the user uses the device, the piston rod of the drive cylinder extends, pushing the connecting rod upward. The connecting rod drives the connecting ring upward, which in turn drives the arc-shaped baffle to flip outward through the pull rod, thus expanding the cylinder and facilitating the discharge of the rubber strip or ball core from the feeding cylinder. When the piston rod of the drive cylinder retracts, it pushes the connecting ring downward, which in turn pushes the arc-shaped baffle to flip inward, sealing the bottom of the feeding cylinder. This automatically opens and closes the bottom of the feeding cylinder, facilitating feeding and discharging.

[0010] Optionally, the exhaust assembly includes exhaust pipes fixedly connected to both sides of the feeding box, an exhaust pump connected to the exhaust pipes, multiple air guide pipes provided on the exhaust pipes, the air guide pipes extending to the feeding cylinder, and branch pipes fixedly connected to the air guide pipes, the branch pipes communicating with the ventilation ring.

[0011] By adopting the above technical solution, when the ball core is processed, the exhaust pump works and draws air through the exhaust pipe and air guide pipe to create a negative pressure state inside the loading cylinder, which slides the loading box to the top of the lower mold and adsorbs the ball core in the cavity of the lower mold into the loading cylinder, thus realizing automatic material discharge.

[0012] Optionally, a notch is provided in the middle of the feeding cylinder, which divides the feeding cylinder into upper and lower parts. A baffle is provided in the notch, which is located above the air inlet pipe. The baffle is used to divide the feeding cylinder into a material preparation trough and a receiving cavity. The upper and lower parts of the feeding cylinder are connected and fixed by a connecting plate. A power component is provided on the feeding box to drive the baffle to slide outward.

[0013] By adopting the above technical solution, when the user uses the baffle, the exhaust space inside the feeding cylinder can be reduced, making it easier to attract the ball core into the feeding cylinder during exhaust. At the same time, it is convenient to put spare rubber strips into the preparation trough. After the ball core is discharged, the baffle is controlled to slide outward, so that the rubber strip automatically falls into the receiving cavity for feeding, saving feeding time.

[0014] Optionally, each baffle includes a left baffle and a right baffle. A baffle rod is fixedly connected to the side of all left baffles away from the right baffle, and a fixing rod is fixedly connected to the side of all right baffles away from the left baffle. The power assembly includes a left pusher cylinder and a right pusher cylinder fixedly connected to the symmetrical sides of the feeding box. Both the left and right pusher cylinders are horizontally arranged and their piston rods are arranged opposite each other. A left linkage rod and a right linkage rod are slidably connected to the feeding box. The left pusher cylinder and the left linkage rod are fixedly connected. The two left linkage rods are fixedly connected to both ends of the baffle rod. The right pusher cylinder and the right linkage rod are fixedly connected. The two right linkage rods are fixedly connected to both ends of the fixing rod.

[0015] By adopting the above technical solution, when the piston rods of the left and right push cylinders retract, they push the left and right baffle plates to move towards each other until they abut, blocking the notch of the upper cylinder. When it is necessary to unload the rubber strip in the spare slot, the piston rods of the left and right push cylinders are controlled to extend, pushing the left and right baffle plates to move in opposite directions, which facilitates the unloading of the rubber strip in the spare slot.

[0016] Optionally, the drive mechanism includes support rods on both sides of the top of the bracket, with a portal frame fixedly connected to the top of the support rods. The feeding box is detachably connected to the top of the connecting frame. The drive mechanism also includes two connecting rods connected to the bracket. An extension rod is fixedly connected to the side of the bracket near the vulcanizing machine. One end of each connecting rod is hinged to the bracket and the extension rod, respectively, and the other end of each connecting rod is hinged to the support rod. A power motor is fixedly connected to the bracket, and the output shaft of the power motor is fixedly connected to the hinge shaft of the connecting rod.

[0017] By adopting the above technical solution, when the user uses the device, the power motor works, driving the connecting rod to rotate around its hinge axis with the bracket. When the power motor drives the connecting rod to rotate inside the vulcanizing machine, so that the feeding box is directly above the upper mold, the power motor rotates in the opposite direction, driving the connecting rod to swing towards the vulcanizing machine, thereby realizing the feeding and unloading of rubber strips and ball cores.

[0018] Optionally, a reinforcing rod is fixedly connected to the bottom of the extension rod, and the end of the reinforcing rod away from the extension rod is fixedly connected to the bracket, forming a triangle between the reinforcing rod, the extension rod, and the side wall of the bracket.

[0019] By adopting the above technical solution, when the user uses the extension rod, it needs to bear part of the weight of the connecting rod. By utilizing the stability of the triangle, the extension rod can be more secure to the support rod and is less prone to deformation.

[0020] Optionally, two limiting posts are fixedly connected to the top of the connecting frame. The top of the limiting posts is rounded. A load-bearing rod is fixedly connected to the outer wall of the feeding box. The load-bearing rod has two insertion holes. The limiting posts are used to be inserted into the insertion holes.

[0021] By adopting the above technical solution, when using the device, the user can attach the load-bearing rod to the top of the connecting frame and insert the limiting post into the limiting hole, thereby connecting and fixing the feeding box and the bracket, which facilitates the disassembly and installation of the connecting frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A feeding box is equipped with multiple feeding cylinders, each with multiple elastic arc-shaped baffles at its bottom. These baffles are evenly spaced along the circumference of the feeding cylinder. A positioning plate is equipped with a drive assembly that drives the arc-shaped baffles to slide outward to expand and open the receiving cavity or to contract inward to close the receiving cavity. A venting ring is provided on the side wall of the feeding cylinder, with vent holes communicating with the inside of the feeding cylinder. An exhaust assembly is connected to the venting ring. A drive mechanism is provided on the support frame to drive the feeding box to reciprocate between the mold and the support frame of the vulcanizing machine. A rubber strip is added to the feeding cylinder, with its bottom located within the receiving cavity formed by the arc-shaped baffles. The drive mechanism drives the feeding box. The material moves between the molds. When the feeding box slides above the lower mold, the drive component drives the arc-shaped baffle to flip outward, causing the arc-shaped plate to expand outward. The rubber strip automatically falls from between the arc-shaped baffles into the cavity of the lower mold, completing the automatic feeding. After the rubber strip forms a ball core on the vulcanizing machine, the drive component drives the rubber strip to expand outward, and the exhaust component works to create a negative pressure state inside the feeding cylinder, adsorbing the processed ball core into the receiving cavity. The drive component drives the arc-shaped baffle to contract and seal the bottom of the feeding cylinder, thereby automatically removing the processed ball core. This replaces the traditional manual feeding and unloading, improving production efficiency, ensuring product quality stability, and reducing labor intensity and safety risks. 2. A notch is provided in the middle of the feeding cylinder, and a baffle is installed in the notch. The baffle includes a left baffle and a right baffle. A positioning rod is fixedly connected to the side of all left baffles away from the right baffle, and a fixing rod is fixedly connected to the side of all right baffles away from the left baffle. The power assembly includes a left pusher cylinder and a right pusher cylinder fixedly connected to the symmetrical sides of the feeding box. Both the left and right pusher cylinders are horizontally arranged and their piston rods are arranged opposite each other. A left linkage rod and a right linkage rod are slidably connected to the feeding box. The left pusher cylinder and the left linkage rod are fixedly connected. The two left linkage rods are fixedly connected to the two ends of the positioning rod. The right pusher cylinder and the right linkage rod are fixedly connected. The two right linkage rods are fixedly connected to the two ends of the positioning rod. The moving rod and the fixed rod are fixedly connected at both ends; the baffle can reduce the exhaust space in the feeding cylinder, making it easier to attract the ball core into the feeding cylinder during exhaust. At the same time, it is convenient to put spare rubber strips into the preparation trough. After the ball core is discharged, the baffle is controlled to slide outward, so that the rubber strip automatically falls into the receiving cavity for feeding, saving feeding time. When the piston rods of the left and right push cylinders retract, they push the left and right baffle plates to move towards each other until they abut, blocking the notch of the feeding cylinder. When it is necessary to unload the rubber strip in the spare trough, the piston rods of the left and right push cylinders are controlled to extend, pushing the left and right baffle plates to move in opposite directions, so that the rubber strip in the preparation trough can be unloaded.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0028] This application provides an automatic loading and unloading device for a vulcanizing machine, referring to... Figure 1 and Figure 2 The system includes a support 1, a feeding box 2, a drive assembly 23, a ventilation assembly, and a drive mechanism 3. The support 1 is located on one side of the vulcanizing machine 4, and the feeding box 2 is mounted on the support 1. A positioning plate 21 is fixedly connected inside the feeding box 2, and multiple feeding cylinders 22 are arranged inside the positioning plate 21. The drive assembly 23 is used to control the opening and closing of the bottom of the feeding cylinders 22. The ventilation assembly is used to adsorb the formed ball cores. The drive mechanism 3 is used to drive the feeding box 2 to reciprocate between the mold of the vulcanizing machine 4 and the support 1. This achieves the effect of automatic loading and unloading of the vulcanizing machine 4, improving production efficiency, ensuring product quality stability, and reducing labor intensity and safety risks. This is because automatic loading and unloading avoids the problems of low efficiency, poor consistency and accuracy, high labor intensity, and high safety hazards associated with manual operation.

[0029] Reference Figure 3 and Figure 4Specifically, the feeding cylinder 22 is vertically arranged with open ends, and its number corresponds one-to-one with the number of cavities on the mold of the vulcanizing machine 4. Multiple elastic arc-shaped baffles 222 are provided at the bottom of the feeding cylinder 22, and these baffles 222 are evenly spaced along the circumference of the feeding cylinder 22. The tops of the arc-shaped baffles 222 are hinged to the bottom of the feeding cylinder 22, while the bottoms are free-ends, with their width decreasing from top to bottom. The bottoms of the arc-shaped baffles 222 abut together to form a closed receiving cavity. The drive assembly 23 includes multiple positioning rods 231 fixedly connected to the bottom of the positioning plate 21. The bottom of the positioning rods 231 is hinged to the arc-shaped baffle 222. A pull rod 232 is fixedly connected to the arc-shaped baffle 222. A connecting ring 233 is provided outside the feeding cylinder 22. The connecting ring 233 is located outside the arc-shaped baffle. A rotating shaft 234 is rotatably connected to the end of the pull rod 232 away from the arc-shaped baffle 222. A sliding groove 235 is opened at the bottom of the connecting ring 233, and the rotating shaft 234 is slidably connected in the sliding groove 235. A drive cylinder 236 is fixedly connected to the top of the positioning plate 21. Multiple drive cylinders 236 are provided, and the drive cylinders 236 are arranged vertically. Their piston rods are upward and the end is fixedly connected to a connecting rod 237. A connecting column 238 is fixedly connected to the bottom of the connecting rod 237. The connecting column 238 is arranged vertically in the axial direction, passes through the positioning plate 21, and is fixedly connected to the connecting ring 233. The connecting column is slidably connected to the positioning plate 21. The drive cylinder 236 can be a single-acting cylinder or a double-acting cylinder. When the piston rod of the drive cylinder 236 extends, it pushes the connecting rod 237 to move upward. The connecting rod 237 drives the connecting ring 233 to move upward, which in turn drives the arc-shaped baffle 222 to flip outward through the pull rod 232, thus expanding the cylinder and facilitating the discharge of the rubber strip or ball core inside the feeding cylinder 22. When the piston rod of the drive cylinder 236 retracts, it pushes the connecting ring 233 to slide downward, which in turn pushes the arc-shaped baffle 222 to flip inward, closing the bottom of the feeding cylinder 22. This automatically opens and closes the bottom of the feeding cylinder 22, facilitating feeding and discharging.

[0030] The arc-shaped baffle 222 can be made of rubber, which has good elasticity and flexibility, or it can be made of spring steel, which has high strength and good elasticity. The arc-shaped baffle 222 can be hinged to the bottom of the feed cylinder 22, or it can be hinged with a pin.

[0031] Specifically, refer to Figure 3 and Figure 5The side wall of the feeding cylinder 22 is provided with a ventilation ring 24, and the ventilation ring 24 has a ventilation hole 241 communicating with the inside of the feeding cylinder 22. Exhaust pipes 242 are fixedly connected to both sides of the feeding box 2, and exhaust pumps are connected to the exhaust pipes 242. Multiple air guide pipes 243 are provided on the exhaust pipes 242, extending to the space between the feeding cylinders 22. Branch pipes 244 are fixedly connected to the air guide pipes 243, and the branch pipes 244 communicate with the inside of the ventilation ring 24. The exhaust pump can be a centrifugal exhaust pump or a Roots-type exhaust pump. After the ball core processing is completed...

[0032] Specifically, refer to Figure 6 The lower mold 42 of the vulcanizing machine 4 is equipped with an ejector mechanism 43. The lower mold 42 has cavities. The ejector mechanism 43 includes an ejector cylinder 431 fixedly connected to the cavity 421. The ejector cylinder 431 is vertically oriented. A top plate 432 is fixedly connected to the end of the piston rod of the ejector cylinder 431. An ejector rod 433 is fixedly connected to the top of the top plate 432. Each cavity of the lower mold 42 has an ejector hole 422, which communicates with the cavity 421. The ejector rod... 433 is slidably connected to the ejector hole 422; after the ball core is processed, the piston rod of the ejector cylinder 431 extends and pushes the ejector rod 433 upward. The ejector rod 433 pushes the ball core upward, causing the ball core and the cavity to be demolded. The exhaust pump works and exhausts air through the exhaust pipe 242 and the air guide pipe 243, making the upper material cylinder 22 under negative pressure. The upper material box 2 slides to the top of the lower mold 42 and adsorbs the ball core in the cavity of the lower mold 42 into the upper material cylinder 22, realizing automatic material discharge.

[0033] Specifically, refer to Figure 3 and Figure 7 The feeding cylinder 22 has a notch 2211 in the middle, which divides it into upper and lower parts. A baffle 25 is installed inside the notch 2211, located above the air inlet pipe, to separate the feeding cylinder 22 into a preparation trough and a receiving cavity. The upper and lower parts of the feeding cylinder 22 are connected and fixed by a connecting plate. The baffle 25 can be made of plastic, which is lightweight and easy to process, or it can be made of aluminum alloy, which is high in strength and corrosion resistant. The baffle 25 reduces the exhaust space inside the feeding cylinder 22, making it easier to draw the ball core into the feeding cylinder 22 during exhaust. At the same time, it facilitates the placement of spare rubber strips in the preparation trough. After the ball core is discharged, the baffle 25 is controlled to slide outward, causing the rubber strip to automatically fall into the receiving cavity for feeding, saving feeding time.

[0034] Specifically, refer to Figure 7 and Figure 8Each baffle 25 includes a left baffle 251 and a right baffle 252. All left baffles 251 are fixedly connected to a baffle rod 253 on the side away from the right baffle 252, and all right baffles 252 are fixedly connected to a fixing rod 254 on the side away from the left baffle 251. A left pusher cylinder 255 and a right pusher cylinder 256 are symmetrically fixedly connected to both sides of the feeding box 2. Both cylinders are horizontally positioned with their piston rods facing each other. A left linkage rod 257 and a right linkage rod 258 are slidably connected to the feeding box 2. The left pusher cylinder 255 and the left linkage rod 257 are fixedly connected, and both left linkage rods 257 are fixedly connected to both ends of the stop rod 253. The right pusher cylinder 256 and the right linkage rod 258 are fixedly connected, and both right linkage rods 258 are fixedly connected to both ends of the fixed rod 254. Relief grooves are provided on the outer wall of the feeding box 2 corresponding to the positions of the left and right linkage rods 257 and 258. The left pusher cylinder 255 and the right pusher cylinder 256 can be thin-type cylinders to save space. When the piston rods of the left pusher cylinder 255 and the right pusher cylinder 256 retract, they push the left baffle plate 251 and the right baffle plate 252 to move towards each other until they abut, blocking the notch 2211 of the upper material cylinder 22. When it is necessary to unload the rubber strips in the preparation trough, the piston rods of the left pusher cylinder 255 and the right pusher cylinder 256 are extended, pushing the left baffle plate 251 and the right baffle plate 252 to move in opposite directions, so as to facilitate the unloading of the rubber strips in the preparation trough.

[0035] Specifically, refer to Figure 9 The drive mechanism 3 includes two connecting rods 31 connected to the bracket 1 and a support rod 32 set on the connecting rods 31. An extension rod 34 is fixedly connected to the side of the bracket 1 near the vulcanizing machine 4. One end of the two connecting rods 31 is respectively hinged to the bracket 1 and the extension rod 34, and the other end of the connecting rods 31 is respectively hinged to the support rod 32. A power motor 33 is fixedly connected to the bracket 1, and the output shaft of the power motor 33 is fixedly connected to the hinge shaft of the connecting rod 31. A portal frame 35 is fixedly connected to the top of the support rod 32, and the feeding box 2 is detachably connected to the top of the connecting frame 35. The power motor 33 can be a stepper motor, which can precisely control the rotation angle, or a servo motor, which has a fast response speed and high control accuracy. When the power motor 33 operates, it drives the connecting rod 31 to rotate around its hinge axis with the bracket 1. When the power motor 33 drives the connecting rod 31 to rotate into the vulcanizing machine 4, so that the feeding box 2 is located directly above the upper mold 41, the power motor 33 rotates in the opposite direction, driving the connecting rod 31 to swing towards the vulcanizing machine 4, thereby realizing the feeding and unloading of rubber strips and ball cores.

[0036] Specifically, a reinforcing rod 341 is fixedly connected to the bottom of the extension rod 34. The end of the reinforcing rod 341 away from the extension rod 34 is fixedly connected to the bracket 1, forming a triangle with the reinforcing rod 341, the extension rod 34, and the side wall of the bracket 1. The reinforcing rod 341 can be made of steel pipe, which has high strength and low cost, or it can be made of I-beam, which has strong load-bearing capacity. Utilizing the stability of the triangle, the reinforcing rod 341 can strengthen the extension rod 34, making it more robust and less prone to deformation.

[0037] Specifically, two limiting posts 36 are fixedly connected to the top of the connecting frame 35. The top of the limiting posts 36 has rounded corners. A load-bearing rod 27 is fixedly connected to the outer wall of the feeding box 2. The load-bearing rod 27 has two insertion holes 271. The limiting posts 36 are used to insert into the insertion holes 271. The cooperation between the limiting posts 36 and the load-bearing rod 27 allows the feeding box 2 to be accurately installed on the connecting frame 35, and at the same time facilitates the disassembly and installation of the connecting frame 35.

[0038] The implementation principle of this embodiment is as follows: the automatic loading and unloading device moves the loading box 2 to a suitable position through the drive mechanism 3; the drive component 23 controls the opening and closing of the arc-shaped baffle 222 to realize the loading of rubber strips and the unloading of ball cores; the ejector mechanism 43 demolds the formed ball cores from the cavity; the exhaust pipe 242 uses negative pressure to adsorb the formed ball cores; and the power component controls the opening and closing of the baffle 25 to replenish spare rubber strips. Compared with the traditional manual loading and unloading method, this method improves production efficiency, ensures the stability of product quality, and reduces labor intensity and safety risks, representing a significant improvement over existing technologies.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
