Technical Field
[0001] This utility model application relates to the field of basketball production and processing technology, and in particular to a basketball surface texture pressing device. Background Technology
[0002] In the basketball manufacturing industry, the surface texture pressing process plays a crucial role in the quality and performance of basketballs. A well-designed surface texture not only enhances the basketball's aesthetics but also significantly improves its grip, elasticity, and hand-feel, thereby enhancing the player's ball-handling experience. Traditional texture pressing processes primarily rely on a combination of molds and hot-pressing technology. Specific patterns are engraved on the mold surface, and the texture is then pressed onto the basketball surface under high temperature and pressure. This process can achieve relatively complex texture structures, meeting the design requirements of different types of basketballs.
[0003] Regarding the aforementioned technologies, the inventors believe that existing surface texture pressing devices are inefficient in the demolding process. Most devices use mechanical ejection or manual assistance for demolding, which not only consumes a lot of manpower and time, but also easily damages the surface texture of the basketball due to uneven force during the ejection process, affecting product quality. Therefore, a basketball surface texture pressing device is proposed to solve the above problems.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The basketball surface texture pressing device provided in this utility model application adopts the following technical solution:
[0007] A basketball surface texture pressing device includes a basketball texture hot pressing device. A base is fixedly connected to the outer wall of the basketball texture hot pressing device. A mold seat is fixedly connected to the outer wall of the base. A pressing mold is fixedly installed on the inner wall of the mold seat. The outer wall of the pressing mold has grooves arranged in a circumferential array. An ejector arc plate is provided on the outer wall of the pressing mold. An outer tube is fixedly connected to the inner wall of the mold seat. An air cavity is provided inside the outer tube. An inner tube is slidably connected to the outer tube through the air cavity, and the inner tube is fixedly connected to the ejector arc plate. A through groove is provided inside the outer tube. Guide grooves are provided on both outer walls of the inner tube. A radial air passage is provided inside the inner tube, and the radial air passage communicates with the guide groove. Multiple oblique holes are arranged in a circumferential array inside the ejector arc plate, and a connecting component is provided between the multiple oblique holes and the radial air passage.
[0008] Preferably, the connecting component includes a circular groove, a connecting air passage, and a uniform groove. The circular groove, the connecting air passage, and the uniform groove are all formed inside the ejector arc plate. The circular groove is connected to the radial air passage. The uniform groove is formed in an annular shape on the inner circumference of the circular groove. The circular groove is connected to the inclined hole through the connecting air passage. The diameter of the inlet end of the connecting air passage is larger than the diameter of the outlet end.
[0009] Preferably, the bottom of the outer tube has an air inlet that is connected to an external air supply source.
[0010] Preferably, the bottom outer wall of the ejector plate is fixedly connected with a plurality of limiting rods, and the plurality of limiting rods are evenly distributed in a circumferential array, and the plurality of limiting rods are slidably connected to the outer tube.

[0012] Preferably, the outer wall of the pressing mold has an air nozzle placement opening.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This device utilizes the cooperation of an outer tube, an inner tube, and an ejector plate to achieve automatic demolding of basketballs using gas drive. After an external air source supplies air to the air chamber, the gas pushes the inner tube to move the ejector plate, completing the initial ejection. At the same time, the unique design of the through groove, guide groove, and connecting components allows the gas to be ejected a second time, forming an air film on the surface of the basketball, achieving secondary ejection. This greatly reduces the friction between the ejector plate and the basketball, preventing damage to the surface texture of the basketball during demolding and ensuring the efficiency and accuracy of demolding.
[0015] 2. This device achieves stable gas transmission and uniform distribution through the design of the circular groove in the connecting component, the connecting air channel, and the uniform groove. The circular groove initially collects and buffers the gas, the uniform groove ensures uniform gas distribution, and the tapered structure of the connecting air channel accelerates gas ejection, ensuring that the gas can efficiently form an air film on the basketball surface, improving the demolding effect and guaranteeing the stability and reliability of gas transmission.

[0022] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.
[0023] A basketball surface texture pressing device includes a basketball texture hot pressing device 1. A base 2 is fixedly connected to the outer wall of the basketball texture hot pressing device 1. The basketball texture hot pressing device 1 is prior art and will not be described in detail here. A mold seat 3 is fixedly connected to the outer wall of the base 2. The base 2 is used to support the entire pressing device and ensure the stability of the pressing process. A mold base 3 is fixedly connected to the outer wall of the base 2. The mold base 3 serves to fix and install the pressing mold 4. The pressing mold 4 is fixedly installed on the inner wall of the mold base 3. The outer wall of the pressing mold 4 has grooves 5 arranged in a circular array. The grooves 5 are used to press the required texture pattern on the surface of the basketball. A matching mold is set above the pressing mold 4 to press the texture of the basketball. The outer wall of the pressing mold 4 is provided with an ejector plate 6, which can eject the basketball from the pressing mold 4 after pressing. An outer tube 7 is fixedly connected to the inner wall of the mold base 3. An air chamber 20 is provided inside the outer tube 7. An inner tube 10 is slidably connected to the outer tube 7 through the air chamber 20. The sliding connection between the outer tube 7 and the inner tube 10 is sealed to prevent gas leakage. The inner tube 10 is fixedly connected to the ejector plate 6. An external air source can supply air into the air chamber 20 through the air inlet 8. After the gas enters the air chamber 20, it pushes the inner tube 10 in the air chamber 20. The inner tube 10 slides inward, thereby moving the ejector plate 6. The outer tube 7 has a through groove 18 inside, which has a stepped structure that is wider at the top and narrower at the bottom. Its bottom diameter is the same as the inner diameter of the air chamber 20, and its top diameter is larger than the diameter of the air chamber 20. Guide grooves 13 are provided on both outer walls of the inner tube 10. When the inner tube 10 moves the ejector plate 6 to a certain height, the bottom of the inner tube 10 enters the wider part of the through groove 18, allowing the gas to move upward from both sides and enter the inner tube through the guide grooves 13. Inside the inner tube 10, a radial air passage 14 is provided, and the radial air passage 14 is connected to the guide groove 13. The inside of the ejector plate 6 has multiple oblique holes 16 arranged in a circular array, and a connecting component is provided between the multiple oblique holes 16 and the radial air passage 14. The gas is ejected from the oblique holes 16 of the ejector plate 6 through the radial air passage 14 and the connecting component of the inner tube 10, thereby ejecting the basketball a second time, separating the basketball from the ejector plate 6, and thus completing the demolding after the texture of the basketball is pressed.
[0024] The connecting component includes a circular groove 12, a connecting air passage 17, and a uniform groove 15. The circular groove 12, the connecting air passage 17, and the uniform groove 15 are all opened inside the ejector arc plate 6, and the circular groove 12 is connected to the radial air passage 14. The circular groove 12 allows the gas to be initially collected and buffered in it, ensuring the stability of the gas when it is delivered to the connecting air passage 17. The uniform groove 15 is opened in a ring on the inner circumference of the circular groove 12. The uniform groove 15 is arranged around the circular groove 12 to play a role in uniformly distributing the gas. The circular groove 12 is connected to the inclined hole 16 through the connecting air passage 17. The diameter of the inlet end of the connecting air passage 17 is larger than the diameter of the outlet end, forming a gas acceleration structure. When the gas enters the connecting air passage 17 from the circular groove 12, the gas velocity will gradually increase due to the gradual decrease in the diameter of the passage. The accelerated gas is ejected at high speed from the inclined hole 16.
[0025] The bottom of the outer tube 7 is provided with an air inlet 8 that is connected to an external air supply source. By connecting to an external high-pressure air source, high-pressure gas is introduced into the air chamber 20 of the outer tube 7. The air inlet 8 can be equipped with valves, pressure regulators and other devices of the external air source to precisely control the flow rate and pressure of the gas entering the air chamber 20.
[0026] Multiple limiting rods 9 are fixedly connected to the bottom outer wall of the ejector plate 6, and the multiple limiting rods 9 are evenly distributed in a circumferential array. The multiple limiting rods 9 are slidably connected to the outer tube 7. Through the slidable connection between the multiple limiting rods 9 and the outer tube 7, the stability of the ejector plate 6 moving up and down is ensured.
[0027] An outer groove 19 is provided inside the outer tube 7 on one side of the air cavity 20. The outer groove 19 has an annular groove structure and is located inside the tube wall of the outer tube 7 on the side close to the air cavity 20. It can accommodate the extension and retraction of the spring member 11. The inner wall of the outer groove 19 is fixedly connected to the spring member 11, and one end of the spring member 11 is fixedly connected to the ejector arc plate 6. When the ejector arc plate 6 moves upward, the spring member 11 receives the pulling force of the ejector arc plate 6. Thus, after the demolding is completed, the spring member 11 releases its elastic potential energy, causing it to drive the ejector arc plate 6 to return to its original position, which is convenient for the next texture pressing process.
[0028] The outer wall of the pressing mold 4 has an air nozzle placement port 21. Before pressing the basketball texture, the air tube is connected to the air nozzle of the basketball, so that the basketball becomes full and the surface of the basketball fits better with the groove 5 on the pressing mold 4.
[0029] The implementation principle of the basketball surface texture pressing device according to the present invention is as follows: Before pressing the basketball texture, the inflation tube is connected to the air valve of the basketball bladder to make the basketball fully inflated. Then, the basketball bladder is placed in the pressing mold 4, and the air valve is accurately placed in the air valve placement opening 21 opened on the outer wall of the pressing mold 4. The design of the air valve placement opening 21 can not only avoid the air valve being squeezed and damaged during the pressing process, but also ensure the accurate position of the air valve, which is convenient for subsequent assembly and inflation. At this time, the ejector plate 6 is tightly pressed by the spring member 11. The spring 11 is attached to the outer wall of the pressing mold 4. One end of the spring 11 is fixed to the inner wall of the outer groove 19 inside the outer tube 7, and the other end is connected to the bottom of the ejector arc plate 6. It is in a naturally extended state, thereby activating the basketball texture hot pressing device 1. This device heats and presses the pressing mold 4. The outer wall of the pressing mold 4 has grooves 5 arranged in a circumferential array. Under the action of pressure and temperature, the desired texture pattern is pressed onto the surface of the basketball. During this process, the base 2 provides stable support for the entire device, and the mold seat 3 firmly fixes the pressing mold 4 to ensure that the pressing process is stable and reliable.
[0030] After the basketball texture is pressed, the demolding process begins. An external air supply source is connected to the air inlet 8 at the bottom of the outer tube 7 via a pipe. The air inlet 8 can be used with valves, pressure regulators, and other equipment to precisely control the flow rate and pressure of the gas entering the air chamber 20. High-pressure gas enters the air chamber 20 of the outer tube 7 through the air inlet 8. Since the outer tube 7 and the inner tube 10 are slidably connected and the connection is sealed, the gas pushes the inner tube 10 to slide upward within the air chamber 20. The top of the inner tube 10 is fixedly connected to the ejector plate 6, which in turn drives the ejector plate 6 along the pressing mold. 4. The outer wall moves upward, initially pushing out the basketball. Because the through-slot 18 inside the outer tube 7 has a stepped structure that is wider at the top and narrower at the bottom, its bottom diameter is the same as the inner diameter of the air chamber 20, and its top diameter is larger than the diameter of the air chamber 20. When the inner tube 10 drives the ejector plate 6 to move upward to a certain height, the bottom of the inner tube 10 enters the wider part of the through-slot 18. At this time, the gas moves upward from both sides, passing through the guide slots 13 on both sides of the outer wall of the inner tube 10 and entering the radial air passages 14 inside the inner tube 10. The radial air passages 14 are connected to the guide slots 13, and the gas passes through the radial air passages 14. The gas enters the connecting assembly inside the ejector plate 6 via channel 14. The circular groove 12 in the connecting assembly is connected to the radial gas channel 14. Gas initially gathers and is buffered within the circular groove 12 to ensure stable gas delivery. A uniformly distributed groove 15 surrounds the circular groove 12 on its inner circumference, serving to distribute gas evenly. The circular groove 12 is connected to the inclined hole 16 via a connecting gas channel 17. The inlet diameter of the connecting gas channel 17 is larger than the outlet diameter, forming a gas acceleration structure. According to fluid mechanics principles, when gas enters the connecting gas channel 17 from the circular groove 12, the gas accelerates due to the change in channel diameter. The low flow rate increases, and the accelerated gas is ejected at high speed from multiple oblique holes 16 arranged in a circular array inside the ejector plate 6, forming an air film on the surface of the basketball. This achieves secondary ejection of the basketball, reduces the friction between the ejector plate 6 and the basketball, and separates the basketball from the ejector plate 6, completing the demolding operation. After demolding, the gas supply is stopped, and the gas pressure in the air chamber 20 disappears. At this time, the compressed spring 11 releases its elastic potential energy, pulling the ejector plate 6 and the inner tube 10 downwards to return to the initial position, waiting for the next basketball texture pressing process.
