Description

Technical Field

[0001] The present invention relates to the technical field of eraser processing, in particular to a kneading and forming device and method for eraser processing. Background Art

[0002] An eraser is a tool used to erase pencil marks. Generally, erasers are made by softening polyvinyl chloride and adding plasticizers. However, now erasers are made by adding auxiliary materials to the elastomer of environmentally friendly plastic styrene and pressing them. In order to ensure that the auxiliary materials and plastic plastic styrene are mixed more evenly, it is often necessary to knead the plastic plastic styrene and the auxiliary materials, which requires the use of a kneading molding device.

[0003] A kneading and molding device for eraser processing disclosed in a patent application with reference announcement number CN211640714U has kneading rods connected to the two side walls of a kneading barrel in an interlaced sliding manner, and a driving wheel is driven to rotate under the drive of a servo motor, so that the rack moves toward the center of the kneading barrel. At this time, the kneading head completes the kneading operation of the eraser raw material. The use of multiple kneading heads for interlaced kneading makes the plastic styrene and the auxiliary materials mixed more evenly, thereby ensuring the processing quality of the eraser.

[0004] Comprehensive analysis of the above reference patents shows the following defects:

[0023] Beneficial Effects

[0024] The present invention provides a kneading and forming device and method for processing an eraser. Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. A kneading and forming device and method for processing erasers. Through the mutual cooperation among a kneading frame mechanism, a driving rod mechanism, a driven gear and a first push rod, the driving rod mechanism can drive the kneading frame mechanism during operation, so that the kneading frame mechanism kneads the eraser raw material in the kneading cylinder mechanism. Under the cooperation of the driven gear and the first push rod, the driving rod mechanism simultaneously pushes the kneading cylinder mechanism to swing back and forth within a preset angle. During the reciprocating swing of the kneading cylinder mechanism, the position of the internal eraser raw material can be continuously changed, so that the eraser raw material can be fully kneaded. During the process, the position of the kneading frame mechanism in the kneading cylinder mechanism is continuously changed. With the change of the kneading frame mechanism, the raw materials at different positions can be further kneaded, thereby increasing the flexibility of kneading and ensuring that all parts of the raw material can be evenly kneaded to avoid the problem of local excess or deficiency.

[0026] 2. A kneading and forming device and method for processing erasers. Through the mutual cooperation among the adjusting rod assembly, the square rod, the kneading rod assembly and the first servo motor, the first servo motor is started regularly to drive the adjusting rod assembly to rotate. Under the limiting action of the annular groove, the left spiral groove and the right spiral groove, multiple kneading rod assemblies can be synchronously approached or synchronously moved away from each other, thereby realizing flexible adjustment of the position of the kneading rod assembly. As the position of the kneading rod assembly changes, raw materials at different positions can be further kneaded, avoiding the problem of uneven processing caused by a single kneading point and optimizing the overall kneading effect.

[0027] 3. A kneading and forming device and method for processing erasers. Through the mutual cooperation between the transverse axis, cams, top plate, kneading rods and springs, when the second servo motor drives the transverse axis to rotate, each cam rotates accordingly. Since adjacent cams are alternately distributed on the upper and lower parts of the transverse axis, as the cams rotate, each kneading rod assembly can be driven to work, so that the adjacent kneading rod assemblies can achieve the purpose of alternately moving up and down. The kneading rod assembly that moves downward can knead the eraser raw material below, and the operation process is simple and convenient.

[0028] 4. A kneading and forming device and method for processing an eraser. Through the mutual cooperation among a driving gear, a second push rod, a driven gear, a first push rod, a first baffle and a second baffle, as the horizontal axis rotates, the driving gear and the second push rod rotate accordingly. During the rotation of the second push rod, the first baffle can be intermittently moved, so that the cylinder body rotates within a preset angle. During the rotation of the driving gear, the driven gear is driven to rotate, and the first push rod rotates accordingly. During the rotation of the first push rod, the second baffle can be intermittently moved, so that the cylinder body rotates in the opposite direction within a preset angle. There is no need to set up a separate driving mechanism to drive the kneading cylinder mechanism to swing. Under the drive of the second servo motor, the kneading cylinder mechanism can achieve the purpose of reciprocating swing within a preset angle, thereby improving energy utilization.

[0051] The embodiment of the invention also provides a kind of kneading and pressing forming method for eraser processing, adopts the kneading and pressing forming device for eraser processing, and concrete method comprises the following steps:

[0052] Step 1, open the sealing cover 46, put the eraser raw material into the cylinder 41, wherein the eraser raw material is plastic styrene and auxiliary materials. After putting it in, close the sealing cover 46, and then start the second servo motor 63. The second servo motor 63 drives the horizontal shaft rod 61 to rotate, and each cam 62 rotates accordingly during the process. Since the adjacent cams 62 are alternately distributed on the upper and lower parts of the horizontal shaft rod 61, as the cams 62 rotate, the top plate 556 can be pushed down intermittently, so that the kneading rod 557 moves down, and the kneading rod 557 that moves down can knead the eraser raw material below.

During the process, as the horizontal axis rod 61 rotates, the driving gear 64 and the second push rod 65 rotate accordingly. During the rotation of the second push rod 65, the first baffle 44 can be intermittently dialed, so that the cylinder body 41 rotates within a preset angle. During the rotation of the driving gear 64, the driven gear 8 is driven to rotate, and the first push rod 9 rotates accordingly. During the rotation of the first push rod 9, the second baffle 45 can be intermittently dialed, so that the cylinder body 41 rotates in the opposite direction within a preset angle, and finally the kneading cylinder mechanism 4 achieves the purpose of reciprocating swing within a preset angle.

[0053] Step 2: During the reciprocating swing of the kneading cylinder mechanism 4, the position of the eraser material inside is constantly changed, and the eraser material is fully kneaded in cooperation with the kneading frame mechanism 5. During the process, the first servo motor 56 operates intermittently according to a preset program to drive the adjusting rod assembly 53 to reciprocate within a set angle range;

[0054] Step three, during the process, the first servo motor 56 is started regularly to drive the adjusting rod assembly 53 to rotate. Under the limiting action of the annular groove 532, the left spiral groove 533 and the right spiral groove 534, the multiple kneading rod assemblies 55 can be synchronously approached or synchronously moved away from each other, so as to realize the flexible adjustment of the position of the kneading rod assembly 55. As the position of the kneading rod assembly 55 changes, the raw materials at different positions can be further kneaded to avoid the problem of uneven processing caused by a single kneading point. During the movement of the kneading rod assembly 55, the top of the top plate 556 is always in contact with the bottom of the corresponding cam 62 to ensure that the top plate 556 can be pushed normally during the rotation of the cam 62. After the kneading is completed, the raw materials are taken out and put into the extruder, and the raw materials are extruded and formed by the extruder, wherein the extruder belongs to the prior art known to those skilled in the art.
