Description

[0001] PRODUCTION PROCESS OF TENNIS BALLS WITH WHISTLE

[0002] I. The technical fields mentioned

[0003] The invention refers to the production process tennis balls with whistle for pets from recycled rubber.

[0004] IL Technical status of the invention

[0005] During the vulcanization process to create the product, a portion of the vulcanized glue that must remain in the couplers of the two and a half molds, which is called bavia in production. After the vulcanization process, bavia will be removed.

[0006] The main waste is the removed Bavia part. In addition, during the production process, there are some products unqualified products (explosive scars, damage, etc.), which are are also called rubber waste.

[0007] Through the vulcanization process of rubber products as network connection between the polymer circuits in the rubber material. Thanks to this process, the material becomes sturdy and meets the physical claims of the rubber product.

[0008] Currently in Vietnam, tennis balls for pets are made from natural rubber or synthetic rubber and some other materials.

[0009] Compared to using primary natural rubber materials, we can utilize a part of its own waste sources in list formula to protect the environment, reduce waste in the production process, besides, still ensuring the functionality and durability of the product.

[0010] III. Technical nature of the invention

[0011] The production process tennis balls with whistle includes the following steps: a) Collect rubber waste; b) Perform to re-check rubber waste to remove strange objects mixed inside; c) Take rubber waste and crushed them into small particles (A batch of 20 kg of waste is rolled in 30 minutes); d) Perform to re-check a second time to remove strange objects again; e) Rolling and mixing rubber waste in step (d) in a closed smelting machine with the following ingredients: 10% natural rubber; 80% rubber waste; 5% coffee grounds and 5% other chemicals; f) Vulcanize the tennis ball core at a temperature of about 150 °C; g) Atach the whistle and stick the felt shell outside the ball core; h) Vulcanization of products; i) Check the finished products.

[0024] V. Detailed invention Description a) Collection of rubber waste products

[0025] Purpose: to receive Bavia parts and non-conforming products (exploded scars, damaged, etc.);

[0026] Operation: Find and remove objects that are not rubber waste;

[0027] Ciaims: Operate quickly and accurately; b) Check

[0028] Purpose: Remove foreign objects inside;

[0029] Operation: Put rubber waste products through the scanner to remove strange objects mixed inside; Claims: operate quickly, avoiding loss; c) Crushed into small grains

[0030] Purpose: Crashed rubber products into small particles. A batch of 20 kg of waste products is rolled in 30 minutes;

[0031] Operation: rolling by specialized industrial machines;

[0032] Claims: operate correctly and quickly, avoid accidents with the rolling machine; d) Second check

[0033] Purpose: Remove strange objects mixed inside;

[0034] Operation: Put rubber waste products that have been rolled into small particles through the scanner to remove strange objects mixed inside.

[0035] Claims: operate quickly, avoiding loss; e) Rolling together with other ingredients in the list formula

[0036] Purpose: Create vulcanized glue for the next step;

[0037] Operation: Rolling and mixing rubber waste and ingredients: 10% natural rubber; 80% rubber waste; 5% coffee grounds and 5% other chemicals;

[0038] Claims: Operation should be accurate and correct quantity within the prescribed time;

[0039] 1) Vulcanization of tennis ball core

[0040] Purpose: Create a tennis ball core;

[0041] Claims: Need to monitor the temperature of the vulcanization process. Operations must be quick and accurate; g) Attach the whistle and stick the felt layer to the outside of the ball core

[0042] Purpose: Attach the whistle directly to the tennis ball core, then stick the felt;

[0043] Claims: Fast, accurate; h) Products vulcanization

[0044] Purpose: ensure the whistle and the outer felt shell cover are securely attached;

[0045] Claims: quickly, avoiding loss; i) Check finished products

[0046] Purpose: ensure products brought to market meet standards;

[0047] Claims: fast, accurate, avoid missing defective products.

[0048] VI. Example of invention implementation a) Raw Materials:

[0049] Raw materials used for production are Bavia parts and unqualified products (exploded scars, damaged, etc.) called rubber waste. Rubber waste after collection is transferred to the production site. Here workers classify, remove object that are not rubber waste; b) Check:

[0050] Check process to remove strange objects mixed inside such as soil, rocks, etc., mixed in rubber waste and retain the rubber waste;

[0051] Rubber waste products are passed through the scanner by workers. The scanner will remove impurities that are not rubber waste products and retain the rubber waste products; c) Crushed into small granules:

[0052] A batch of 20 kg of waste products is rolled granu 30 minutes to form small particles; d) Second review to ensure complete elimination impurities that are not rubber waste products. e) Rolling and mixing rubber waste and components: 10% natural rubber; 80% rubber waste; 5% coffee grounds and 5% other chemicals; f) Vulcanization of tennis ball core; g) Attach the whistle and stick the felt to the outside of the ball core; h) Vulcanization of products; i) Check finished products.
