Description

Technical Field

[0002] Chalk is a widely used tool in daily life, generally used for writing on blackboards. The main component of chalk is calcium sulfate, a white precipitate that is not easy to decompose and has particles larger than dust.

[0003] When making chalk, the raw materials need to be mixed, and then the evenly mixed materials are introduced into a mold and dried to obtain the finished chalk. However, when traditional equipment is stirring and mixing the raw materials, the raw materials are easily unevenly dispersed and agglomerated into small particles. After being injected into the mold to make chalk, when the chalk is used for writing, the agglomerated small particles on the chalk are prone to breakage, affecting its use. Utility Model Content

[0023] As shown in the figure, the embodiment of the utility model is described in detail:

[0024] A chalk processing device comprises a mixing box 1, a transverse plate 2, a mixing shaft 5, a mixing plate 6, a discharge pipe 4 and a filter plate 8; the mixing box 1 is used for mixing raw materials, the transverse plate 2 is fixed at the upper end of the mixing box 1, the mixing shaft 5 rotates on the transverse plate 2, a plurality of mixing plates 6 are fixed on the mixing shaft 5, the discharge pipe 4 is arranged at the lower end of one side of the mixing box 1, and the filter plate 8 is arranged in the mixing box 1 and is located between the mixing shaft 5 and the discharge pipe 4;

[0025] When in use, all the raw materials of chalk are added into the mixing box 1, and then the first motor installed on the horizontal plate 2 is started, so that the first motor drives the mixing shaft 5 to rotate, and then drives the multiple mixing plates 6 to rotate in the mixing box 1, so as to form the mixing of the raw materials. After the mixing is completed, the valve on the discharge pipe 4 is opened, and the evenly mixed material will pass through the filter plate 8 and be discharged from the discharge pipe 4, and then be transported to the mold for the next step of preparation;

[0026] By setting the filter plate 8, the mixed raw materials can be filtered when they are discharged from the mixing box 1, so that the small particles that are not evenly dispersed in the raw materials are intercepted in the mixing box 1, thereby preventing the small particles agglomerated in the raw materials from flowing out with the raw materials and affecting the quality of the chalk.

[0027] Further:

[0028] By arranging the filling pipe 3 at the upper end of the mixing box 1 and away from the discharge pipe 4, the added raw materials can be directly dropped into the rotating range of the mixing plate 6, thereby achieving better mixing.

[0029] As shown in the figure:

[0030] The lower part of the filter plate 8 is provided with a plurality of filter holes, and the baffle 12 slides on the filter plate 8 close to the stirring shaft 5 ; the screw 13 rotates on the upper end of the baffle 12 , and the screw 13 is threadedly connected with the upper end of the filter plate 8 .

[0031] The baffle 12 is provided to block the multiple filter holes on the filter plate 8, thereby preventing the raw material from initially passing through the filter holes and moving to the other side of the filter plate 8, thereby preventing the raw material from contacting the stirring plate 6 and affecting the stirring effect of the stirring plate 6 on the raw material.

[0032] After the stirring is completed, when the material is discharged, the screw 13 is rotated, and the screw 13 threadably drives the baffle 12 to make the baffle 12 rise on the filter plate 8, so that multiple filter holes leak out, forming a filtration of the stirred raw materials, preventing small particles agglomerated in the raw materials from flowing out with the raw materials, thereby affecting the quality of the chalk.

[0033] As shown in the figure:

[0034] The frame 9 is sleeved on the mixing box 1, and the frame 9 passes through the mixing box 1 and is fixedly connected to the filter plate 8; the spring 10 is arranged between the frame 9 and the outer side of the mixing box 1, and the elastic force of the spring 10 makes the filter plate 8 press against the side plate of the mixing box 1 where the discharge pipe 4 is arranged.

[0035] When the raw materials are being stirred and the baffle 12 blocks the multiple filter holes, the frame 9 is pushed to squeeze the spring 10, and the frame 9 will drive the filter plate 8 and the baffle 12 to slide in the stirring box 1, thereby squeezing the space where the raw materials are located. When the frame 9 is released, the elastic force of the spring 10 will push the frame 9 to drive the filter plate 8 and the baffle 12 to return to their original positions in the stirring box 1, even if the size of the space where the raw materials are located is restored, the frame 9 is pushed back and forth to squeeze or restore the space where the raw materials are located, so that the raw materials can flow horizontally and further contact with the multiple stirring plates 6, thereby improving the stirring efficiency.

[0036] As shown in the figure:

[0037] The lower end of the stirring shaft 5 passes through the stirring box 1 and is fixed with an eccentric wheel 7 . The frame 9 is provided with an arm plate at the end away from the discharge pipe 4 , and the arm plate is slidably connected with the eccentric wheel 7 .

[0038] When the stirring shaft 5 rotates, the eccentric wheel 7 will be driven to rotate with the stirring shaft 5 as the axis. When the eccentric wheel 7 rotates to the support arm plate and contacts the support arm plate, it will squeeze the support arm plate, so that the support arm plate drives the frame 9 to move, thereby forming the movement of the filter plate 8 and the baffle 12. After the eccentric wheel 7 is separated from the support arm plate, the elastic force of the spring 10 will restore the support arm plate to its original position so that it can contact again next time, thereby forming the stirring shaft 5 rotating while being able to drive the filter plate 8 and the baffle 12 to move, thereby increasing the kinetic energy output of the first motor.

[0039] Further:

[0040] The rotating wheel 11 rotates on the arm plate, and the rotating wheel 11 is rollingly connected with the eccentric wheel 7.

[0041] The rolling contact between the rotating wheel 11 and the eccentric wheel 7 replaces the original sliding contact between the eccentric wheel 7 and the support arm plate, so that the eccentric wheel 7 can drive the filter plate 8 and the baffle plate 12 to move, thereby avoiding energy loss.

[0042] Further:

[0043] The four corners of the lower end of the mixing box 1 are all provided with legs. The four legs support the mixing box 1, providing installation and movement space for the eccentric wheel 7 and the runner 11.
