The four utility model patents applied for by Jiangxi Xinruifeng Biochemical Co., Ltd. were recently approved by the State Intellectual Property Office.

It is reported that they are: "a pump before the inhalation device" (patent number: ZL201220055382.4), "vacuum pipe self-closing device" (patent number: ZL201220506829.5), "air oil and water separator wear protection device" (patent No.: ZL201220506492.8), Resin Adsorption Experimental Device (patent number: ZL201220506866.6). In addition to the two utility model patents “Multifunctional Experimental Vehicle” and “Sealer” approved by the company in 2011, the company currently holds six utility model patents.

The acquisition of these six utility model patents has created favorable conditions for the company to continue to evaluate new and high-tech enterprises in 2013 and better solve the problem of enterprise declaration qualifications and threshold access. In order to increase the visibility of the company and expand its influence, the company strives for the national and local governments. Project establishment and financial support laid a good foundation.

In another development, the company has seven patent applications that have entered the substantive review of the first-instance review or the second-instance review reply period. Judging from the current feedback, Xinruifeng is expected to obtain at least one more patent in 2013.

Fittings and Parts of Crushing Machines

There are several fittings and parts commonly found in crushing machines, including:

1. Jaw Plates: These are the main wear-resistant parts of the crushing machine. They are fixed on the jaw body and provide the crushing surface for the material.

2. Toggle Plates: These plates are connected to the toggle beam and help in adjusting the opening of the crusher. They also protect the machine from overloading.

3. Eccentric Shaft: This is a critical component that provides the rotational motion to the jaw crusher. It is usually made of high-grade forged steel and is responsible for transmitting the crushing force to the material.

4. Flywheel: The flywheel is a heavy metal wheel attached to the eccentric shaft. It helps in maintaining the momentum of the crushing machine and reduces the load fluctuations during the crushing process.

5. Bearings: Bearings are used to support the rotating components of the crushing machine, such as the eccentric shaft and the flywheel. They ensure smooth operation and reduce friction.

6. Crushing Chamber: The crushing chamber is the space between the fixed jaw plate and the movable jaw plate. It is where the actual crushing of the material takes place.

7. Wedges: Wedges are used to adjust the gap between the fixed and movable jaw plates. They help in controlling the size of the crushed material.

8. Springs: Springs are used to provide the necessary force for the jaw plates to return to their original position after crushing the material.

9. Belt and Pulley System: This system is used to transmit power from the motor to the crushing machine. It consists of a belt connected to the motor and pulleys attached to the flywheel and eccentric shaft.

10. Guard Plates: Guard plates are used to protect the crushing machine from damage caused by foreign objects or excessive wear.
