Description

Technical Field

[0001] The utility model relates to the technical field of glassine paper production, in particular to a single-side coating production device for glassine paper. Background Art

[0002] Glassine paper is a kind of industrial paper. Glassine base paper is made into glassine paper after coating. Glassine paper is a common material for making barcode labels, stickers, tapes or sticky industrial products, especially suitable for rotary and flat die cutting; Glassine paper has the functions of high temperature resistance, moisture resistance, oil resistance, etc., and is generally used for packaging in food, medicine and other industries.

[0003] A Chinese patent with authorization announcement number CN215629023U discloses a single-sided coating production equipment for glassine paper for medical purposes, including a roller, a discharge box, a storage box, a fixed plate, a rotating plate, two groups of racks, two groups of gears and two groups of first springs; the storage box is provided with a feed port; the discharge box is provided with a discharge port, and the discharge box is provided with a retreat component; both ends of the roller are provided with a first rotating shaft; the two groups of first rotating shafts are rotatably connected to the discharge box; the fixed plate is installed in the discharge box, the fixed plate is provided with a first through hole, and the fixed plate is provided with two groups of mounting holes; one end of the rotating plate is rotatably connected to the fixed plate; the rotating plate is provided with a second through hole; the two groups of gears are respectively installed on the two groups of first rotating shafts; the two groups of racks are respectively slidably connected to the inner walls of the two groups of mounting holes, and are slidably connected to the lower end surface of the rotating plate; the two ends of each group of first springs are respectively connected to each group of racks and the inner wall of the discharge box.

[0004] The above-mentioned disclosed patent still has the following technical defects: 1. There is a certain gap between the roller and the discharge port (otherwise the paint cannot be evenly applied to the roller). After the coating work is completed, the excess paint inside the storage box will flow into the working area along the gap, causing pollution and waste; 2. Since the surface of glassine paper is relatively smooth and the angle between it and the roller is small, slippage is likely to occur between the glassine paper and the roller, and the roller cannot be driven to rotate smoothly.

DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1-Figure 3 As shown, the glassine paper single-side coating production equipment proposed in this embodiment includes a coating box a1, a coating roller 3, a mounting frame a4 and a pressure roller 5.

[0021] The upper end of the paint box a1 has an opening 101; the paint roller 3 is rotatably mounted on the paint box a1 and located inside the opening 101; a scraper 17 is mounted on the paint box a1, and the scraper 17 is located inside the opening 101. The paint on the surface of the glassine paper can be scraped flat by the scraper 17.

[0022] The pressure roller 5 is rotatably mounted on the mounting frame a4, and the pressure roller 5 is located directly above the coating roller 3. Both ends of the mounting frame a4 are connected with elastic components, which include a guide slide bar 13, a spring 15 and a limit ring b16. The guide slide bar 13 is vertically arranged on the coating box a1, and the mounting frame a4 is slidably arranged on the guide slide bar 13. The limit ring b16 is installed on the upper end of the guide slide bar 13, and the spring 15 is sleeved on the guide slide bar 13; a threaded portion 131 is arranged on the upper end of the guide slide bar 13, and the upper end of the guide slide bar 13 is threadedly connected to the limit ring b16 through the threaded portion 131. Through the arrangement of the above structure, the height position of the limit ring b16 can be adjusted. When the limit ring b16 moves downward, the spring 15 is compressed, thereby increasing the pressure of the pressure roller 5 on the glassine paper.

[0023] In this embodiment, during operation, the mounting frame a4 is pulled upward to separate the pressure roller 5 from the coating roller 3, and then the glassine paper is placed between the coating roller 3 and the pressure roller 5, and then the mounting frame a4 is released, and the pressure roller 5 is driven to return to its original position and press on the upper end surface of the glassine paper under the elastic force of the spring 15, so as to increase the friction between the glassine paper and the surface of the coating roller 3. In the process of driving the glassine paper to move, the movement of the glassine paper drives the rotation of the coating roller 3 and the pressure roller 5, and the coating roller 3 contacts the coating box a1 at its bottom end during the rotation, and as the coating roller 3 continues to rotate, its surface is covered with coating, and the glassine paper contacts the coating roller 3 so that its surface is coated with coating, and the excess coating on the coating roller 3 flows into the interior of the coating box a1.

[0024] Embodiment 2

[0025] like Figure 1 As shown, a glassine paper single-sided coating production equipment proposed in this embodiment, compared with the first embodiment, in this embodiment, further includes a coating box b2, a discharge pipe 11 is provided between the coating box b2 and the coating box a1, and a solenoid valve 10 is installed on the discharge pipe 11; an ultrasonic liquid level sensor (not shown) is installed on the top wall of the coating box a1, and a controller 12 is installed on the coating box b2, and the controller 12 is electrically connected to the solenoid valve 10 and the ultrasonic liquid level sensor. The ultrasonic liquid level sensor can detect the liquid level height of the coating inside the coating box a1. When the liquid level inside the coating box a1 drops to the set position, the ultrasonic liquid level sensor feeds back a signal to the controller 12, and the controller 12 controls the opening of the solenoid valve 10. At this time, the coating stored in the coating box b2 flows into the coating box a1 through the discharge pipe 11, thereby realizing automatic replenishment of the coating inside the coating box a1.

[0026] Embodiment 3

[0027] like Figure 1 and Figure 2 As shown, a glassine paper single-sided coating production equipment proposed in this embodiment, compared with the first embodiment, an anti-deviation mechanism is installed on the coating box a1, and the anti-deviation mechanism includes a mounting frame b14, a limiting roller 6, a driving member and two limiting rings a7. The mounting frame b14 is arranged at the end of the coating box a1, the limiting roller 6 is rotatably installed on the mounting frame b14, and the two limiting rings a7 are both sleeved on the limiting roller 6. The driving member is installed on the mounting frame b14 and is used to drive the two limiting rings a7 to move closer to or away from each other. The driving member includes a bidirectional screw rod 9 and a rotating handle 91. The bidirectional screw rod 9 is rotatably installed on the mounting frame b14, and the rotating handle 91 Installed at the end of the bidirectional screw rod 9, two limit rings a7 are connected with connecting sliders 8, and the two connecting sliders 8 are symmetrically arranged on the bidirectional screw rod 9 and are threadedly connected to the bidirectional screw rod 9. The glassine paper is placed on the limit roller 6 and placed between the two limit rings a7. The two limit rings a7 can be used to limit the glassine paper to prevent the glassine paper from being displaced in position during movement. The rotating handle 91 is used to drive the bidirectional screw rod 9 to rotate, so that the two limit rings a7 can be driven to move closer or farther away from each other, thereby achieving the limiting work of glassine paper of different sizes.

[0028] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
