Description

Technical Field

[0001] The present application relates to a grinding device, and in particular to a rubber ball mold line positioning grinding device. Background Art

[0002] In the manufacture of industrial rubber products, spherical rubber parts are often used, such as ball valves, etc. Rubber balls are a widely used product. These spheres are usually made of multiple rubber sheets, and the molded products often form a prominent mold line at the seam. In order to ensure the appearance and performance of the product, especially in the competitive or professional fields, these mold lines must be removed or polished smooth.

[0003] Traditionally, the parting line grinding of rubber balls is done manually. Workers use sandpaper or other abrasives to manually grind these parting lines to achieve the desired smoothness. The main steps of this method are generally to manually locate the exact position of the parting line. Then use sandpaper to repeatedly rub the parting line until the line is no longer obvious. Finally, check and correct any uneven or incompletely processed parts.

[0004] Although the method of manually grinding the mold line still has its applicability in small-scale production or craft production, this method has significant disadvantages in large-scale production environments. Specifically, because the grinding work is completely dependent on the skills and experience of individual workers, the quality between different products may vary significantly. Worker fatigue and distraction can cause fluctuations in grinding quality. Manual grinding is a labor-intensive and time-consuming process. In large-scale production, this process will significantly slow down production and increase production costs. In addition, long-term manual grinding may affect the health of workers, especially the health of their hands and lungs. Continuous physical labor may cause occupational diseases such as musculoskeletal diseases, and the dust generated by the grinding process may cause respiratory diseases.

[0005] Therefore, there is an urgent need to develop an automated rubber ball mold line grinding device to solve the problems caused by the above-mentioned manual grinding. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a rubber ball mold line positioning and polishing device. The device should be able to quickly operate to align the mold line and perform polishing in an efficient and consistent manner, thereby improving production efficiency, reducing labor costs, and improving the consistency of product quality.

[0007] To achieve the above-mentioned purpose, the present application discloses a rubber ball mold line positioning and polishing device, comprising a machine platform, a driving mechanism, a manual elastic pressing mechanism and a manual polishing assembly, wherein the driving mechanism and the manual elastic pressing mechanism are horizontally installed on the table of the machine platform opposite to each other, forming a polishing position for placing the rubber ball, and driving the rubber ball to rotate; the manual polishing assembly is hinged on the table of the machine platform through an elastic rotating shaft and is located on the side of the polishing position, and the manual polishing assembly is moved close to the polishing position around the hinge shaft under manual operation; the machine platform is also provided with a chip removal port opposite to the polishing position.

[0008] Furthermore, the driving mechanism includes a motor and a first chuck mounted on the main shaft of the motor.

[0009] Furthermore, the hand-controlled elastic pressing mechanism comprises a base mounted on the table of the machine, a guide rod horizontally passing through the base, and a material pressing lever hinged on the machine and opposite to the tail end of the guide rod; a spring is installed between the guide rod and the base to realize the reset of the guide rod after horizontal extension and contraction; a second chuck opposite to the driving mechanism is installed on the front end of the guide rod; the guide rod is pushed to move in the horizontal direction by operating the material pressing lever to form a grinding position

[0010] Furthermore, the first chuck and the second chuck are both bowl-shaped.

[0011] Furthermore, the manual grinding assembly includes a base frame hinged on the table top of the machine through an elastic hinge shaft, a driving motor installed on the base frame, a belt rack installed on the frame, and a grinding operating rod for driving the belt rack to rotate around the elastic hinge shaft. The belt rack has multiple guide wheels and at least one driving wheel that cooperates with the driving motor and is driven by the driving motor. A grinding belt is provided on the guide wheel and the driving wheel.

[0012] Furthermore, a laser marker is installed on the machine through a bracket. The laser marker faces the grinding position, and the laser line emitted by the laser marker is used to control the matching position of the rubber ball mold line and the manual grinding component.

[0013] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0014] 1. The driving mechanism in the device drives the rubber ball to rotate at the grinding position, ensuring that the ball can be evenly polished and improving the consistency of the grinding quality. At the same time, the application of the laser marker further improves the positioning accuracy of the grinding part, ensuring that each grinding is accurately aligned with the mold line.

[0015] 2. The design of the manual elastic pressing mechanism and the manual grinding assembly allows the operator to finely control the grinding process through simple manual operation. At the same time, the spring device ensures that the guide rod can automatically reset after use, which is convenient for continuous use and reduces the physical burden of the operator.

[0024] Example:

[0025] Figure 1 An exemplary structure for achieving the technical purpose of the present application is disclosed. As shown in the figure, this embodiment provides a detailed structure of a rubber ball parting line positioning and polishing device. The device is intended to improve the polishing quality and efficiency of the rubber ball parting line, and is particularly suitable for the needs of mass production in the sporting goods and children's toy manufacturing industries. The device includes a machine 1, a drive mechanism 2 on the table mounted on the machine 1, a hand-controlled elastic top-pressing mechanism 3 also mounted on the table 1 and horizontally opposite to the drive mechanism 2, and a hand-controlled polishing assembly 12. The drive mechanism 2 and the hand-controlled elastic top-pressing mechanism 3 are spaced and matched to form a polishing position 6.

[0026] More specifically, in the rubber ball mold line positioning and polishing device, the machine 1 serves as a support and mounting platform for the entire device, taking into account stability, durability, and ease of operation. The machine 1 is usually made of high-strength steel or cast iron to ensure sufficient stability and shock resistance. These materials can effectively reduce vibration during operation and improve processing accuracy.

[0027] In this embodiment, the driving mechanism 2 is responsible for providing the rotational power of the rubber ball to ensure that the rubber ball keeps rotating evenly during the grinding process, so as to achieve the purpose of evenly grinding the parting line. In terms of composition, the driving mechanism 2 includes a motor 4 and a first chuck 5. More specifically, the motor 4 has a main shaft, and a bowl-shaped first chuck 5 is installed on the main shaft.

[0028] It should be understood that the first chuck 5 is designed to be bowl-shaped so as to better fit and fix the spherical workpiece. As a more optimal solution, the first chuck 5 has an anti-skid texture inside to increase the friction when clamping the rubber ball and prevent the ball from sliding during processing.

[0029] In this embodiment, as one of the components constituting the grinding position 6, the manual elastic pressing mechanism 3 is used to fix and position the rubber ball so as to perform precise grinding operation. Specifically, in terms of structure, it includes a base 7, a guide rod 8, a spring 9, a second chuck 10 and a material pressing lever 11. The base 7 is fixed on the table of the machine table to form the installation foundation of the mechanism. The guide rod 8 is designed as a horizontal rod passing through the center of the base 7. The material selection is usually hardened steel or other wear-resistant materials to resist wear and stress during operation. One end of the guide rod 8 is relatively matched with the material pressing lever 11, and the other end is equipped with the second chuck 10. This structure allows the guide rod 8 to move horizontally in the base 7 to achieve precise positioning and pressing of the rubber ball. In order to achieve the reset of the guide rod 8, the spring 9 is installed between the guide rod 8 and the base 7 to achieve automatic reset of the guide rod. The material pressing lever 11 is located at the tail end of the guide rod 8. The operator controls the position of the guide rod 8 and the second chuck 10 by pushing and pulling this rod. After the material pressing lever 11 is manually pushed for grinding, the spring 9 helps the guide rod to return to the initial position, which is convenient for material unloading and continuous operation.

[0030] As a further description of this embodiment, during implementation, after the rubber ball is placed on the grinding position 6, the operator manually operates the material pressing lever 11 to push the guide rod 8 to make the second clamp 10 approach the first clamp 5, thereby clamping the rubber ball. This clamping ensures the stability of the rubber ball during the grinding process.

[0031] On the basis of the above structure, the manual grinding assembly 12 is a key part specially used to perform grinding operations. The assembly can be manually adjusted to adapt to the precise grinding of rubber balls of different sizes and mold lines. Structurally, the manual grinding assembly 12 has a base frame 13, a drive motor 14, a belt frame 15 and a grinding operating rod 16, wherein the base frame 13 is hinged on the table of the machine 1 through an elastic hinge shaft, allowing the manual grinding assembly 12 to rotate around the hinge shaft during operation to facilitate the adjustment of the grinding angle. The base frame 13 has a stable structure, and the material selection is usually steel or aluminum alloy to support the strength and long-term use during the grinding process.

[0032] The driving motor 14 mounted on the base frame 13 is responsible for driving the movement of the grinding belt 17. The grinding operating rod 16 is connected to the base frame 13, allowing the operator to manually adjust the position and pressure of the grinding assembly 12 to meet different grinding requirements.

[0033] It should be understood that, as a preferred embodiment, the drive motor 14 is connected to a speed regulating system, allowing the operator to adjust the grinding speed according to different grinding requirements.

[0034] As one of the components of the manual grinding assembly 12, a belt frame 15 mounted on the base frame 13 is provided with a plurality of guide wheels and at least one driving wheel, and these wheels cooperate with a grinding belt 17 to complete the grinding action. The grinding belt 17 is a special abrasive belt suitable for high-speed grinding and long-term use.

[0035] It is understandable that the manual grinding assembly 13 can be manually moved closer to or away from the rubber ball through the grinding operating rod 16, allowing precise control of the grinding pressure and position. The operator can adjust the grinding angle and pressure as needed to ensure that the mold line is evenly and finely processed.

[0036] As an important auxiliary component, the laser marker 18 is used to provide an accurate indication line to help the operator locate the parting line of the rubber ball to ensure the accuracy of grinding. The laser marker 18 is installed on a bracket above the machine 1, and the bracket can adjust the position and angle of the laser marker 18 to align the grinding position. The laser marker 18 can emit a small and high-brightness laser line, which is directly projected onto the rubber ball to mark the exact position of the parting line.

[0037] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
