Description

Technical Field

[0001] The utility model relates to a facial tissue folding machine, and particularly to a paper embossing device for preventing dirt. Background Art

[0002] In the prior art, the base paper enters the embossing roller after uncoiling. Through the extrusion of the upper and lower embossing rollers, an embossing pattern is formed on the paper surface.

[0003] In order to prevent the paper from sticking to the embossing roller during the extrusion process, it is necessary to apply a thin oil film (transparent mineral oil, food grade, commonly known as white oil) on the surfaces of the upper and lower embossing rollers through an oiling cloth (in direct contact with the embossing roller).

[0004] The oiling cloth is always kept in a wet state. The oil supply system operates once every 20 minutes, each time for 20 seconds. The oil pump transports a certain dose of white oil evenly to the width of the oiling cloth through the pipeline and the fine holes of the pipeline to keep the oiling cloth wet.

[0005] During the production process, a mixture of oil and paper powder will fall onto the surface of the base paper at the place where the upper embossing roller (smooth roller) contacts the oiling cloth, resulting in product contamination and customer complaints. Summary of the Invention

[0006] Utility Model Objective: Aiming at the above-mentioned shortcomings, the utility model provides a paper embossing device for preventing dirt and ensuring the cleanliness of the paper.

[0007] Technical Solution: To solve the above problems, the utility model adopts a paper embossing device for preventing dirt, which includes an upper embossing roller, a lower embossing roller arranged directly below the upper embossing roller, and an oiling cloth arranged on the side of the upper embossing roller and in direct contact with the upper embossing roller. The base paper is located between the upper embossing roller and the lower embossing roller. A tray is arranged between the base paper and the oiling cloth. The length and width of the tray are both larger than those of the oiling cloth, and the vertical projection of the part of the oiling cloth in contact with the upper embossing roller is within the receiving range of the tray.

[0008] Further, four sides of the tray extend upward to form a dirt-containing space, and the cross-section of the tray is U-shaped.

[0009] Further, it also includes a tray support. The tray support includes a fixing part for fixing the whole tray support and a support part. The support part is fixedly connected to the fixing part. The support part is a V-shaped groove with an upward opening. Circular tubes extending outward are arranged at both ends of the tray, and the circular tubes are placed in the V-shaped groove to realize the installation of the tray.

[0010] Further, two long holes are opened in the fixing part of the tray support. The upper embossing roller and the lower embossing roller are supported by a support frame. The tray support is fixed to the support frame through bolts passing through the long holes, and the relative position between the tray support and the support frame is adjusted through the long holes.

[0011] Further, there is a gap between the edge of the tray close to the upper embossing roller and the upper embossing roller, and the gap range is 2-3 mm.

[0012] Further, a number of reinforcing ribs are fixedly connected along the length direction of the receiving space of the tray, and the extending direction of the reinforcing ribs is parallel to the width direction of the tray.

[0013] Further, the tray is made of stainless steel material. The tray bracket is made of carbon steel material.

[0014] Beneficial effects: Compared with the prior art, the utility model has the advantage that by installing a dust receiving tray under the oiling cloth of the embossing machine, it is possible to prevent the oil dust on the embossing machine and the oil dust on the oiling cloth from falling into the paper strip folding during the production process, and to avoid the production of finished products flowing into the market and causing dirty complaints.

[0019] As Figure 1 shown, in this embodiment, an anti-dirty paper embossing device is provided. In order to prevent pollutants from falling onto the surface of the base paper from the oiling cloth, a tray 5 is now designed and installed below the upper embossing roller 1 and the oiling cloth 3 and above the base paper 4. The vertical projection of the contact part between the oiling cloth and the upper embossing roller is located within the receiving range of the tray to collect the fallen pollutants.

[0020] The tray 5 is made of a 1.5-mm-thick stainless steel plate, and the four sides extend upward to form a space for accommodating dirt, with a shape similar to a "U" shape, a depth of 100 mm, a width of 300 mm, and a length of 3400 mm, which is slightly longer than the oiling cloth 3. Two DN25 round tubes 51 are welded on each side, and the distance between the two round tubes 51 is 180 mm and the length is 180 mm.

[0021] To prevent the tray from deforming, a varying number of reinforcing ribs 52 can be installed along the length direction in the groove. The extending direction of the reinforcing ribs 52 is parallel to the width direction of the tray. The distance between the reinforcing ribs 52 is about 700 mm, which is more appropriate, taking into account both the weight and the ease of cleaning.

[0022] The pallet support 6 is made of a carbon steel plate with dimensions of 300mm * 300mm * T14mm. Two long strip holes 62 with a width of 12mm and a length of 5cm are reserved in the horizontal direction at the upper part, which is convenient for fine-tuning the relative position between the support and the upper embossing roller. The lower half of the plate pallet support 6 is composed of two 5# carbon steel angle irons with a length of 180mm, and the openings face directly upward, forming a V-shaped groove 61 with an upward opening. This can facilitate the direct placement of the two side struts into the groove during pallet installation. While ensuring stability, it is also conducive to subsequent cleaning operations.

[0023] The two pallet supports 6 are respectively fixed on the support frames on both sides of the upper and lower embossing rollers using M10 nuts. Threads are tapped on the inner side of the support frames, and M10 * L35 bolts are used for fixation. The pallet support is fixed to the support frame by bolts passing through the long strip holes 62, and the relative position between the pallet support 6 and the support frame is adjusted through the long strip holes 62, thereby facilitating the adjustment of the gap between the pallet 5 and the upper embossing roller 1. The gap between the pallet 5 and the upper embossing roller 1 is controlled between 2 - 3mm, which can prevent friction with the roller surface while facilitating the collection of all pollutants as much as possible.

[0024] The cleaning of the pallet is preferably arranged during the shift handover to reduce the impact on production capacity, generally from 7 am to 8 am. The pallet is cleaned once every other day, and it can be lifted outside the machine for a deep cleaning once a week. After the dust collection pallet was fabricated and installed at the end of May, the number of customer complaints about oil stains decreased from 3 in May to 0 in June, preventing the oil dust on the embossing machine and the oil dust on the oiling cloth from falling into the paper folding during production, avoiding the situation where the produced finished products flow into the market and cause customer complaints about dirt, and enhancing the product image.
