Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic rubber, in particular to a grinding machine for improving the output of thermoplastic rubber. Background Art

[0002] Thermoplastic rubber, also known as thermoplastic elastomer, is a material that has the properties of both rubber and thermoplastic plastics. When processing thermoplastic rubber, the rubber raw materials can be ground into powder through a grinder.

[0003] When the existing thermoplastic rubber grinding machines on the market are used to grind rubber raw materials, generally after one grinding, the ground powder needs to be taken out from the equipment, and then put into the equipment again for secondary grinding until the ground powder meets the demand. Each time the grinding process is performed, the powder needs to be manually taken out and then manually added to the equipment, which will affect the grinding efficiency during processing, thereby reducing the output of rubber. For this reason, we propose a grinding machine that can increase the output of thermoplastic rubber. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A grinding machine for improving the output of thermoplastic rubber, comprising a chassis 1, a grinding chamber 2 is provided inside the chassis 1, a transmission shell 3 is fixedly installed on the right side of the top of the chassis 1, a first motor 4 is fixedly installed on the outside of one side of the transmission shell 3, gears are arranged at both ends of the inside of the transmission shell 3, the two gears are meshed, the output shaft of the first motor 4 is fixedly connected to the right gear, and a grinding roller 5 is arranged at one end of the two gears located inside the grinding chamber 2; a conveying shell 6 is fixedly installed on the outside of the side of the chassis 1 away from the first motor 4, a circulation mechanism 7 is arranged inside and outside the top of the conveying shell 6, and the circulation mechanism 7 includes a third motor 701, an auger 702 and a return port 703; an adjusting mechanism 8 is provided at the inner bottom end of the chassis 1, and the adjusting mechanism 8 includes a feed chute 801, a material guide chamber 802 and a material guide plate 803; a second motor 9 is provided on the outer side of the chassis 1 close to the material guide plate 803, and the output shaft of the second motor 9 passes through the chassis 1 and is fixedly connected to the middle part of one side of the material guide plate 803; a third motor 701 is fixedly installed on the top of the conveying shell 6, and an auger 702 is provided at one end of the inner part of the conveying shell 6; a return port 703 is penetrated between the conveying shell 6 and the top of the chassis 1, and the bottom end of the conveying shell 6 is connected to the material guide chamber 802;

[0027] In this embodiment, after one grinding, the electric push rod 10 is started. After the electric push rod 10 is started, the baffle 12 is retracted from the storage groove 11 until the discharge groove 801 is opened. At this time, the powder after one grinding falls into the guide chamber 802 along the discharge groove 801, and then slides into the conveying shell 6 on the left through the guide plate 803. The third motor 701 drives the auger 702 inside the conveying shell 6 to rotate synchronously. After the auger 702 rotates, the powder after one grinding is sent from the return port 703 to the grinding chamber 2 for secondary grinding. In this way, when performing multiple grindings, there is no need to take the powder out of the equipment, which improves the grinding efficiency and thus the output.

[0028] like Figure 4 As shown, a material guide chamber 802 is provided at the bottom end of the chassis 1, and the material guide chamber 802 is connected to the middle of the grinding chamber 2 through a material discharge chute 801, and a material guide plate 803 is movably installed at the bottom end of the material discharge chute 801;

[0029] In this embodiment, when the secondary grinding is completed, the second motor 9 is started. After the second motor 9 is started, it drives the guide plate 803 in the middle of the guide chamber 802 to flip to the right until the guide plate 803 blocks the left side of the guide chamber 802, and then the baffle 12 is opened again to open the top of the discharge chute 801. In this way, the powder after the secondary grinding will slide along the right side of the guide chamber 802 to the position of the discharge port 14, and finally the powder can be taken out from the position of the discharge port 14, thereby achieving the purpose of facilitating discharge.

[0030] like Figure 4As shown, an electric push rod 10 is fixedly installed on the outside of the bottom end of the chassis 1 near the transmission housing 3, and storage grooves 11 are opened on both sides of the top of the chassis 1 located at the feeding trough 801. A baffle 12 is movably installed inside the storage groove 11, and the output shaft of the electric push rod 10 is fixedly connected to the right side of the baffle 12.

[0031] In this embodiment, when the electric push rod 10 is started, it controls the baffle 12 to move forward and backward in the storage groove 11. When the baffle 12 moves forward, the top of the feed chute 801 is closed. When the feed chute 801 moves backward, the top of the feed chute 801 is opened. This makes it easier to prevent powder from falling into the feed chute 801 during grinding.

[0032] like Figure 1 and Figure 2 As shown, a hopper 13 is fixedly installed at the middle of the top of the chassis 1, and a material guide chamber 802 is provided with a material discharge port 14 at one end on the right side of the chassis 1, and both sides of the material guide chamber 802 are inclined downward;

[0033] In this embodiment, the upper hopper 13 is used to put the rubber raw material into the chassis 1, and the lower feed port 14 is used to take out the powder material on the right side of the guide chamber 802.

[0034] Working principle: During operation, the rubber raw material is placed from the position of the upper hopper 13 into the grinding chamber 2 inside the chassis 1, and then the first motor 4 is started. After the first motor 4 is started, it drives the gear on the right side of the transmission shell 3 to rotate. After the gear on the right rotates, it drives the meshing gear on the left to rotate. After the two gears rotate in opposite directions, they drive the two grinding rollers 5 inside the grinding chamber 2 to grind the rubber raw material that has entered. After one grinding, the electric push rod 10 is started. After the electric push rod 10 is started, the baffle 12 is retracted from the receiving groove 11 until the discharge trough 801 is opened. At this time, the powder after one grinding falls into the guide chamber 802 along the discharge trough 801, and then slides into the conveying shell 6 on the left through the guide plate 803. At this time, the third motor 701 is started, and the third motor 701 is started Then it drives the auger 702 inside the conveying shell 6 to rotate synchronously. After the auger 702 rotates, the powder ground once is sent back into the grinding chamber 2 from the return port 703 for secondary grinding. During the secondary grinding, it is necessary to insert the baffle 12 into the receiving groove 11 in advance to close the top of the discharge chute 801. When the secondary grinding is completed, the second motor 9 is started. After the second motor 9 is started, it drives the guide plate 803 in the middle of the guide chamber 802 to flip to the right until the guide plate 803 blocks the left side of the guide chamber 802, and then open the baffle 12 again to open the top of the discharge chute 801. In this way, the powder ground twice will slide along the right side of the guide chamber 802 to the position of the discharge port 14, and finally the powder can be taken out from the position of the discharge port 14.
