Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field, concretely relates to a kind of white liquor packing sheet material efficient edge sealing equipment. BACKGROUND

[0002] At present, white liquor packing sheet material edge sealing equipment structure is relatively simple, and most of them use traditional mechanical transmission manual edge sealing mode. The edge sealing part is generally sealed by a person holding a spraying edge device. The edge sealing material is applied by a nozzle, and it is difficult to accurately control the amount of glue. The pressing mechanism is not stable in pressure application and maintenance. In terms of process conditions, the edge sealing speed is generally slow, with a thickness of about 0.3-0.5 meters per minute, and the adaptability to white liquor packing sheet materials of different thickness and material is limited, usually only applicable to sheet materials with a thickness of 0.2-0.5mm and a single paper material. The main problems are as follows:

[0003] 1. Low edge sealing efficiency: manual feeding and single edge sealing result in long idle time of the equipment, and the overall edge sealing speed is limited, which cannot meet the needs of large-scale white liquor packaging production.

[0005] 3. Poor equipment adaptability: it is difficult to handle sheet materials of different thickness and material, and the edge sealing effect of new composite sheet materials or sheet materials with thickness beyond the conventional range is not good or even impossible. INVENTION CONTENTS

[0046] Referring to Fig. 1 , the edge sealing assembly 7 includes: guide rail 11, U-shaped baffle 3, telescopic rod 4, pressing plate 5 unit, two guide rails 11 are respectively arranged on the two sides of material loading table 1;The U-shaped baffle 3 is slidably arranged on the guide rail 11;Telescopic rod 4 is arranged on one side of U-shaped baffle 3, for pushing the U-shaped baffle 3 along guide rail 11 to move to edge sealing assembly 7;Telescopic rod 4 is equipped with servo motor.

[0047] The pressing plate 5 unit is arranged on one side of the U-shaped baffle 3, and is used for clamping and fixing a plurality of pieces of material and the U-shaped baffle 3. The pressing plate 5 unit comprises a pneumatic cylinder 6 arranged on the U-shaped baffle 3, and a pressing plate 5 connected with the telescopic end of the pneumatic cylinder 6.

[0048] The material loading table 1 is driven by a high-precision linear guide rail 11 and a servo motor, and the positioning accuracy can reach ±0.1 mm, so as to ensure the accuracy of the material feeding position. A plurality of pneumatic cylinders 6 with independently adjustable pressure are arranged by using a pneumatic pressing mode. The pressing force is monitored in real time by a pressure sensor, and the pneumatic cylinder 6 pressure is automatically adjusted by a control system according to the thickness and material of the material, so as to ensure the stability of the pressure in the edge sealing process.

[0049] In some embodiments, the edge sealing assembly 7 comprises a top ink box 8, a bottom ink box 10, an upper grinding roller unit, a lower grinding roller unit, and two top ink boxes 8 arranged above the material loading table 1 by a support 2; the bottom ink box 10 is arranged below the material loading table 1; the upper grinding roller unit cooperates with the top ink box 8 to realize edge sealing on the upper side of the material; and the lower grinding roller unit cooperates with the bottom ink box 10 to realize edge sealing on the lower side of the material.

[0050] Referring to Fig. 2 , the upper grinding roller unit comprises a first top grinding roller 706, a second top grinding roller 707, and a third top grinding roller 708, two first top grinding rollers 706 are respectively arranged in rotation in the two top ink boxes 8, two second top grinding rollers 707 are respectively arranged obliquely above the two first top grinding rollers 706, and the two second top grinding rollers 707 do not contact each other, and the third top grinding roller 708 is arranged in rotation between the two top ink boxes 8, and the two second top grinding rollers 707 are respectively used for transferring ink from the first top grinding roller 706 to the third top grinding roller 708.

[0051] Still referring to Fig. 2 , the lower grinding roller unit comprises a first bottom grinding roller 704, a second bottom grinding roller 705, and two first bottom grinding rollers 704 are respectively arranged in rotation in the bottom ink box 10, and the two first bottom grinding rollers 704 do not contact each other, and the second bottom grinding roller 705 is arranged in rotation above the two first bottom grinding rollers 704, and the two first bottom grinding rollers 704 are respectively used for transferring ink from the bottom ink box 10 to the second bottom grinding roller 705.

[0052] The edge sealing part adopts a wheel shaft rotating ink belt mode, rolls out the edge sealing ink, and transfers it to the material to be sealed. In order to control the amount of ink, a two-stage and three-stage grinding roller mode is adopted.

[0053] The ordinary paper liquor packaging sheet material with a thickness of 0.3 mm is selected for edge sealing operation. Firstly, a plurality of sheet materials are placed on the loading table 1, and the sheet materials are accurately positioned by the included angle formed by the baffle 3 and the telescopic rod 4. At this time, the air pipe ventilation driving cylinder 6 starts to work, and the cylinder 6 pushes the pressing plate 5 to firmly fix the sheet material. During the fixing process, the pressure sensor monitors the pressing force in real time. Since the sheet material is 0.3 mm ordinary paper, the control system automatically adjusts the pressure of the cylinder 6 to a proper value according to the preset program, so that the displacement of the sheet material during the edge sealing process is avoided, and the damage of the sheet material caused by excessive pressure is avoided.

[0054] Then, the cylinder 6 is extended by the telescopic rod 4, slides along the slide rail, and stably transports the sheet material into the edge sealing assembly 7 fixed on the support 2. In the edge sealing assembly 7, eight grinding rollers are driven to rotate by a servo motor (not shown in the figure). Two first top grinding rollers 706 rotate in the top ink box 8 to dip the appropriate amount of ink, and two first bottom grinding rollers 704 rotate in the bottom ink box 10 to dip the appropriate amount of ink. Then, two second top grinding rollers 707 uniformly dip the ink on the first top grinding rollers 706, the second bottom grinding rollers 705 uniformly dip the ink on the first bottom grinding rollers 704, and the third top grinding rollers 708 uniformly dip the ink on the second top grinding rollers 707. The sheet material passes between the rotating third top grinding rollers 708 and the second bottom grinding rollers 705 at a constant speed to complete the double-side high-speed edge sealing.

[0055] It should be noted that the loading table 1 is provided with a notch, and the second bottom grinding roller 705 is exposed through the notch to realize the bottom edge sealing of the sheet material by the second bottom grinding roller 705.

[0056] During the edge sealing process, since the wheel shaft rotating ink and the multi-stage grinding roller control ink amount are adopted, the ink is uniformly applied, the color of the edge sealing part is consistent, and there is no ink overflow and white edge phenomenon. After detection, the qualified rate of the edge sealing quality of the batch of paper liquor packaging sheet materials reaches 97%, and the edge sealing speed is stably maintained at 3.2 meters per minute. Compared with the traditional equipment, the edge sealing efficiency is significantly improved, and the large-scale production demand is completely met. After the edge sealing, the edge of the sheet material is combined with the main part tightly, the paper fibers do not separate when the edge sealing part is torn by hand, the edge sealing is firm and reliable, the edge sealing line is straight and uniform in width, there is no obvious unevenness under light irradiation, and good flatness is presented, which greatly improves the appearance quality of the product.

[0057] The above only describes the preferred embodiments of the present application, and is used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
