Description

Return gum conveying device

Technical Field

The utility model relates to a tire manufacturing equipment part mechanism specifically is a return and glue conveyor.

Background

The extrusion production of the inner liner in the tire manufacturing process is to extrude a rubber raw material through an extruder and then press the rubber material into a rubber sheet through a calender, and the rubber sheet is conveyed to a subsequent procedure after being cut into a qualified size.

The waste rubber strips after the rubber sheets are cut need to be sent back to the extruder for reprocessing through the rubber return conveying belt, but for rubber materials with low part viscosity, the rubber materials can be adhered to the rubber return conveying belt due to high viscosity of the returned rubber materials, the rubber sheets can often cause the rubber return conveying belt to be blocked, accumulated rubber is generated to cause the rubber return conveying belt to stop, the rubber needs to be cleaned in an artificial assistance manner, the problems are eliminated through monitoring at any time, the labor intensity is high, the danger is large, and the production efficiency is low.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model aims to solve the technical problem that a replace artifical glue removing return to glue conveyor is provided.

Can solve above-mentioned technical problem return to glue conveyor, its technical scheme includes the scrap rubber strip after will calendering the film cutting to the extruder return to glue conveying mechanism, the institute is different:

1. the glue returning conveying mechanism comprises glue returning conveying belts arranged on front and rear conveying rollers, the front and rear conveying rollers are arranged on the front and rear end parts of the left and right frames, and the waste glue strips are conveyed forwards from back to back on the glue returning conveying belts.

2. An unpowered roller is arranged in front of an outlet of the glue returning conveying belt, the unpowered rollers are mounted on the left and right supports, and the upper roller surface of the unpowered roller is flush with the belt surface of the glue returning conveying belt.

Furthermore, the left and right brackets are respectively arranged on the front end surfaces of the left and right frames.

Conventionally, the front-end conveying roller is set as an active roller driven by a reduction motor.

The utility model has the advantages that:

1. the utility model discloses return and glue among the conveyor structure, be equipped with unpowered roller in the exit of returning gluey conveyer belt, because the area of contact of useless adhesive tape and unpowered roller is little, therefore useless adhesive tape is difficult to paste on unpowered roller and realize that the pay-off is unobstructed.

2. The utility model discloses in the structure, under the combined action of the quick rotatory tensile force that produces of weight of scrap rubber strip itself and unpowered roller for the difficult adhesion of scrap rubber strip is on returning the gluey conveyer belt, thereby has reduced artificial intervention and has glued clearly, has alleviateed intensity of labour, has improved production efficiency.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a top view of the embodiment of fig. 1.

And (3) identifying the figure number: 1. a conveying roller; 2. a glue returning conveying belt; 3. a frame; 4. a support; 5. an unpowered roller; 6. a speed reducing motor.

Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The utility model discloses return and glue conveyor, include the waste adhesive tape after will rolling the film cutting return from what the calender carried to the extruder and glue conveying mechanism.

The glue returning conveying mechanism comprises a glue returning conveying belt 2, the glue returning conveying belt 2 is wound and installed on a front conveying roller 1 and a rear conveying roller 1, the left and right shaft ends of the front conveying roller 1 are respectively installed on the front end parts of a left frame 3 and a right frame 3 through a left bearing and a right bearing, the left and right shaft ends of the rear conveying roller 1 are respectively installed on the rear end parts of the left frame 3 and the right frame 3 through a left bearing and a right bearing, one shaft end of the front conveying roller 1 is connected with an output shaft of a speed reducing motor 6 through a shaft coupling in an installing mode, the speed reducing motor 6 is installed on the frames 3 on the same side through a machine base, the speed reducing motor 6 serves as power to drive the front conveying roller 1 to rotate, and the glue returning conveying belt 2 moves forwards to drive waste adhesive tapes to be conveyed from the rear end to the front end, as shown in fig. 1 and 2.

An unpowered roller 5 (capable of freely rotating easily) close to one side of the extruder is arranged at an outlet of the front end of the adhesive return conveying belt 2, the left and right shaft ends of the unpowered roller 5 are mounted at the front end parts of the left and right brackets 4 through left and right bearings, the rear end parts of the left and right brackets 4 are mounted on the front end surfaces of the left and right frames 3 respectively, a set short distance is kept between the unpowered roller 5 and the adhesive return conveying belt 2, and the upper roller surface of the unpowered roller 5 is flush with the belt surface of the adhesive return conveying belt 2 or is slightly lower than the belt surface of the adhesive return conveying belt 2, as shown in fig. 1 and fig. 2.

The utility model discloses an operation mode does:

1. the speed reducing motor 6 is started to drive the adhesive returning conveyer belt 2 to convey the waste adhesive tape on the adhesive returning conveyer belt from the calender to the extruder.

2. When the waste rubber strips are conveyed to the outlet of the rubber returning conveying belt 2, the waste rubber strips are manually pulled to be lapped on the unpowered roller 5, and the unpowered roller 5 rotates under the pull of the gravity of the waste rubber strips.

3. The falling waste rubber strip is pulled into the feeding port after being torn off by the extruder.
