Description

TECHNICAL FIELD

[0001] The utility model relates to a hot plasticity rubber ball, in particular to a hot plasticity rubber ball applied to the field of baseball. BACKGROUND

[0002] In addition to the ball used is cheaper than traditional baseball, the ball bat material used in soft baseball can also be selected to be lighter, and the ball bat is less likely to cause breakage, and the glove is mostly used to be cheaper, so soft baseball is more popular among young people, and its safety is relatively high, and it is more suitable for young people. At present, the main users of soft baseball are usually pupils aged 8 to 12 or older people, and the use of soft baseball can reduce the possibility of sports injuries, so soft baseball has a certain market in modern society.

[0003] In addition, the traditional soft baseball is usually made of natural rubber, which must be placed in a semicircular ball-shaped mold to form two hollow hemispheres, and then combined by adhesive, and then trimmed to complete. However, such soft baseball has the following defects:

[0004] Because the two hemispheres must be bonded by adhesive, the bonding surface of the two hemispheres cannot be stably matched, so it cannot be ensured that the two hemispheres can be stably combined with each other. Moreover, the cost of adhesive itself is a considerable expense, and the adhesive effect may be reduced due to the influence of external factors such as use period, external force and environment. When the adhesive effect is reduced, the two hemispheres may be offset, affecting the use feeling, and more seriously, the soft baseball may disintegrate due to the loss of adhesive effect.

[0005] In addition to soft baseball in modern society, there is also soft tennis. The manufacturing method of soft tennis is the same as that of soft baseball. The current process is to first use a mold to make a hemisphere, then use adhesive to bond the two hemispheres, and then trim. However, it also has the problems of reduced adhesive effect and high cost.

[0006] Therefore, the present inventor has invested a lot of time in researching related knowledge, developing and researching related products, and has undergone many experiments and tests, and finally a hot plasticity rubber ball with simple and fast manufacturing, no adhesive and stable structure after forming is developed, so as to improve the above defects and meet the needs of the public. UTILITY MODEL CONTENTS

[0007] Therefore, in order to achieve the above-mentioned purpose and improve the shortcomings of the prior art, the main purpose of the present application is to provide a thermoplastic rubber ball, which can quickly and stably complete the combination of each structure during the manufacturing process, and the process does not require any adhesive, which avoids the combination of the structure through the adhesive, so that the quality is unstable, and the cost of the adhesive is high.

[0008] The utility model provides a thermoplastic rubber ball, wherein the thermoplastic rubber ball has two hemispherical parts, each hemispherical part has an arc surface on the side not facing each other, and there is an ultrasonic fusion part between each hemispherical part.

[0009] Each arc surface has a plurality of concave lines.

[0010] Each hemispherical part has a groove on the side facing each other, and each groove is connected to each other.

[0011] Each arc surface has a plurality of convex blocks, each convex block is arranged at a distance from each other, and each convex block is arranged in a suture shape.

[0012] Each arc surface has at least one mark block.

[0013] According to the above-mentioned technical definition of the utility model technology, the advantage is that the thermoplastic rubber ball is fused by the ultrasonic fusion machine, the two hemispherical parts are fused with each other, the structure of the formed thermoplastic rubber ball is more stable, which avoids the huge cost of using adhesive for bonding, and the bonding effect is easily affected by external factors and reduced, so that the ball body has the possibility of splitting at any time, which proves that the utility model indeed has practicality and progressiveness, and is worth popularizing in the industry.

[0023] In order to clearly illustrate the above objects and advantages of the present application, and to further show the features and advantages of the present application, the embodiments of the present application will be described in detail hereinafter with reference to the drawings, in which Figures 1 to 8 The present application provides a thermoplastic rubber ball 1, wherein the thermoplastic rubber ball 1 has two hemispherical portions 11, each of the hemispherical portions 11 has an arc surface 112 on the side not facing each other, and an ultrasonic melting portion 12 is provided between the hemispherical portions 11.

[0024] The utility model discloses a half sphere part 11 is fused through ultrasonic fusion machine 2, and before the melting process has not ended, ultrasonic fusion machine 2 will continuously pressurize two half sphere parts 11, simultaneously, high temperature is generated by high frequency vibration and is in molten state to two half sphere parts 11, after cooling, two half sphere parts 11 will solidify again and melt each other and form, the position of each half sphere is formed ultrasonic fusion part 12, and continuously pressurizing can avoid the loosening caused by removing pressure when not completely fusing, so that two half sphere parts 11 can more stably complete the fusion, and when two half sphere parts 11 are combined, only the position of mutual adhesion is in molten state and solidifies again, not all of the whole is in molten state and solidifies again, using ultrasonic fusion machine 2 to combine two half sphere parts 11, in addition to reducing the cost, it can produce efficiently and stably and quickly without needing adhesive and without needing the assistance of multiple molds, to save the cost, and using thermoplastic rubber raw material particles as material, it is beneficial to subsequent operation, so that the formed thermoplastic rubber ball 1 is more stable after two half sphere parts 11 solidify and combine again, and it is not easy to disintegrate under external force, and it can also avoid the situation that natural rubber is used as the main material, and the natural rubber needs to be collected, so as to cause environmental pollution, in addition, the natural rubber may become too soft and sticky due to too much heat in summer, and it becomes too hard in winter, and the process is relatively difficult to control, on the contrary, the thermoplastic rubber has high heat resistance, and it will not become soft and sticky before reaching the melting point, and it will not become hard due to too cold weather, so it is more controllable in the process, furthermore, the thermoplastic rubber ball 1 made of thermoplastic rubber raw material particles can be recycled and reused when the ball is split and damaged due to excessive external force, which is more environmentally friendly than using natural rubber, as shown in Figures 1 to 8 .

[0025] In addition, in order to respond to the special design of part of the ball, each arc surface 112 further has a plurality of protrusions 1121, each protrusion 1121 is arranged at intervals between each other, and each protrusion 1121 is arranged in a seam line shape, the protrusions 1121 arranged in a seam line shape can make the hand feeling of the formed thermoplastic rubber ball 1 more close to different balls with seam lines, and can make the rotation of the thermoplastic rubber ball 1 affected by air resistance and other factors, so that the tail of the ball is better, and the bounce amplitude is larger, as shown in Figure 1 and Figure 4 .

[0026] Further, since some ball types have special specifications, such as the regulation that the soft baseball must be a hollow ball, each of the hemispherical portions has a groove 111 on the side facing the other hemispherical portion. The grooves 111 of the two hemispherical portions 11 correspond to each other during the melting process, so that the formed thermoplastic rubber ball 1 is a hollow ball. This thermoplastic rubber ball 1 can be used in the field of soft baseball. Conversely, if the thermoplastic rubber ball 1 is used in other ball types, such as tennis, the hemispherical portions 11 do not have grooves 111, i.e., the finished product is a solid thermoplastic rubber ball 1. The user can decide whether to make grooves 111 in the hemispherical portions 11 by using a mold before performing the subsequent melting operation by the ultrasonic melting machine 2, as shown in Figure 2 , Figure 3 , Figure 5 and Figure 6 .

[0027] Further, in order to make the formed thermoplastic rubber ball 1 have greater distance and stability during flight, and to make the user's feel closer to the partial ball types with grooves, each of the curved surfaces 112 further has a plurality of grooves 1122. The grooves 1122 can reduce the resistance and increase the lift during flight, and improve the controllability of the thermoplastic rubber ball 1, as shown in Figure 1 and Figure 4 .

[0028] In addition, since many ball types have different specifications according to different competitions or different age groups of users, the sizes of various specifications of balls differ slightly, and it is difficult to distinguish them with the naked eye. In order to facilitate the user to distinguish, each of the curved surfaces 112 further has at least one marking block 1123. The marking block 1123 can be used to mark the size of the ball, making it easy for the user to select and use, and can also be used to mark the trademark for the user to refer to when purchasing, as shown in Figure 1 and Figure 4 .
