Description

Technical Field

[0001] The utility model relates to the technical field of toilet paper pressure point mechanisms, in particular to a pressure point mechanism for toilet paper production. Background Art

[0002] In order to make multiple layers of toilet paper tight during the production process, two embossing rollers are often used to press the multiple layers of paper. The pressing points can form a variety of patterns to ensure that the toilet paper is not only beautiful, but also can make the multiple layers of paper relatively tight. The problem with the prior art is that during the process of the existing embossing rollers pressing the paper, toilet paper debris or dust and debris in the workshop are often attached to the embossing rollers. The debris remaining on the embossing rollers will affect the quality of embossing. The traditional solution is to contact the embossing roller with a brush so that the embossing roller contacts the brush during its rotation, so as to achieve the effect of cleaning the debris on the surface of the embossing roller. However, the brush will wear out after long-term use, and the debris attached to the brush is also easy to re-adhere to the embossing roller. Based on the above situation, it is necessary to design a pressing point mechanism for toilet paper production to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0024] Reference Figure 1-Figure 5 As shown, a pressure point mechanism for toilet paper production includes two embossing rollers installed on a frame 1 and a driving member 4 for driving the two embossing rollers to rotate. The frame 1 is also provided with a dust blowing assembly for cleaning the surface of the embossing rollers. The dust blowing assembly includes an air supply member 6 arranged on the frame 1 and a dust blowing pipe arranged at the output end of the air supply member 6. The output end direction of the dust blowing pipe 7 is the same as the horizontal tangent direction of the embossing roller. The frame 1 is provided with multiple air supply members 6 with dust blowing pipes 7 at the output ends, and the multiple air supply members 6 are evenly spaced and linearly arranged along the width direction of the frame 1.

[0025] Specifically, Figure 1 and Figure 2As shown, the two embossing rollers on the frame 1 are driven to rotate by the driving member 4, and the toilet paper is transported between the two embossing rollers. The two embossing rollers are provided with dot patterns, and the two embossing rollers are respectively the first embossing roller 2 and the second embossing roller 3. When rotating, the toilet paper is squeezed, and a pattern consistent with the dot pattern is pressed out on the toilet paper. The toilet paper after the pressing point is not only beautiful, but also can ensure that the multiple layers of toilet paper are tightly connected. The problem with the existing technology is that when the existing first embossing roller 2 and the second embossing roller 3 press the toilet paper, debris will be generated on the embossing roller. If the debris is not cleared in time, it will cause the toilet paper to be pressed. The quality is low. Based on the above situation, the utility model sets an air supply part 6 and a dust blowing pipe 7 on the frame 1 to blow dust on the surface of the embossing roller, so that the debris on the embossing roller can be cleared in time, and the output direction of the dust blowing pipe 7 is consistent with the horizontal tangent direction of the embossing roller, which can ensure that the debris attached to the embossing roller is subjected to force along the horizontal direction and is easier to separate from the embossing roller. It should be further explained that the air supply part 6 can adopt an air pump, a blower or other equipment that can provide air with a flow rate. Considering that the greater the air pressure provided, the debris on the embossing roller is easier to be blown away, the use of an air pump with adjustable pressure is more effective.

[0026] Furthermore, a guide air tube 8 is provided at the output end of the dust blowing tube 7, the cross-section of the guide air tube 8 is triangular, the input end of the guide air tube 8 connected to the dust blowing tube 7 is at the bottom edge of the triangular guide air tube 8, the output end of the guide air tube 8 with a triangular cross-section is arranged at the tip position, and the input end of the guide air tube 8 and the straight line where the input end of the guide air tube 8 is located are in the same direction as the horizontal tangent of the embossing roller.

[0027] Specific as Figure 3 and Figure 4 As shown, the flowing air enters the guide air tube 8 from the center position of a bottom edge of the triangular guide air tube 8, and is discharged from a tip position of the triangular guide air tube 8, blowing in the horizontal tangent direction of the embossing roller, so that the debris is separated from the embossing roller. The guide air tube 8 is arranged in a triangle, which can accelerate the airflow as the guide air tube 8 gradually closes, and has a better impact effect on the debris.

[0028] Further, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an arc-shaped cover 5 is provided at the output end of the guide air tube 8, a connecting port 501 is provided on the side where the arc-shaped cover 5 is connected to the guide air tube 8, an accommodating port 502 for accommodating part of the embossing roller is provided below the arc-shaped cover 5, a dust collecting port 503 is provided on the side of the arc-shaped cover 5 away from the guide air tube 8, and a storage mesh cover 9 is provided on the dust collecting port 503.

[0029] Specifically, an arc-shaped cover 5 is provided at the output end of the guide air duct 8 to prevent debris from escaping. At the same time, a receiving opening 502 is provided below the arc-shaped cover 5 to accommodate part of the embossing roller. After the airflow enters the interior of the arc-shaped cover 5, it is guided by the arc-shaped cover 5 and the entrained debris can more easily enter the interior of the storage mesh cover 9. The interior of the storage mesh cover 9 can facilitate the collection of debris.

[0030] Furthermore, the bottom of the storage net cover 9 has a winding and extending ridge-shaped storage portion 903.

[0031] Among them, Figure 8 and Fig. 9 As shown, the bottom of the storage mesh cover 9 has a ridged storage portion 903 that extends in a circuitous manner, which can prevent debris from entering the mesh cover and remaining in a dispersed state inside the storage mesh cover 9. A moistened sponge strip 904 can be provided inside the ridged storage portion 903 so that the debris can be adhered to the inside of the ridged storage portion 903.

[0032] Furthermore, the guide air tube 8 and the arc-shaped cover 5 are fixed by welding.

[0033] The guide air duct 8 and the arc-shaped cover 5 are fixed by welding, which can ensure that the arc-shaped cover 5 and the guide air duct 8 form a solid integral structure and avoid shaking of the two, thereby causing changes in the direction of the airflow.

[0034] Furthermore, the guide air tube 8 and the storage net cover 9 are detachably connected.

[0035] Among them, Figure 8 As shown, the storage net cover 9 and the guide air tube 8 are detachable, which can facilitate the pouring out of the debris inside the storage net cover 9. Figure 8 In one detachable implementation, the input port of the guide air duct 8 is provided with a rim 901, and a fixing hole 902 is provided on the rim 901. The storage net cover 9 can be fixed to the guide air duct 8 through bolts and the fixing hole 902. When there are a lot of debris inside the storage net cover 9, the debris inside can be taken out by disassembling the guide air duct 8.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
