Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to an auxiliary paper feeding device for the paper feeding mechanism of a laminating machine. Background Technology

[0002] Laminating machines can be divided into two main categories: instant laminating machines and pre-coated laminating machines. This is a specialized laminating machine for paper, board, and laminated products. It combines paper and laminated products by applying pressure with rubber rollers and heated rollers. The laminating machine is often used in conjunction with a paper feeding mechanism. Stacked sheets of paper to be laminated are placed on a paper placement table. A suction mechanism picks up the sheets one by one and pushes them out. Then, a pressing mechanism on a conveyor belt presses the pushed-out portion onto the conveyor belt, effectively removing the paper from the stack. However, there is often a gap between the paper placement table and the conveyor belt, and their end faces are at different angles. Furthermore, the speed at which a portion of the paper is pushed out to the pressing mechanism is much faster than the conveyor belt's running speed. This makes the process of the paper crossing the gap between the paper placement table and the conveyor belt and being pressed by the pressing mechanism uncontrollable. In existing equipment, the paper arches upwards when pressed by the pressing mechanism due to the angle and speed, causing some bending and wrinkling in the pushed-out portion. This can damage some thinner sheets, requiring improvement. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an auxiliary paper feeding device for a laminating machine's paper feeding mechanism. The device includes a mounting frame and an auxiliary transfer device. The mounting frame is positioned between the paper placement table and the conveyor belt of the paper feeding mechanism. The auxiliary transfer device is mounted on the mounting frame and includes a fan, a connecting duct, a lower air outlet rod, an adjusting beam, a suspension rod, and a pair of blocking rollers. Both the fan and the air outlet rod are mounted on the mounting frame. The air outlet rod is located below the gap between the paper placement table and the conveyor belt. The connecting duct of the air outlet rod is connected to the fan. The top of the lower air outlet rod has several evenly spaced air holes. The adjusting beam is mounted on the mounting frame and located above the air outlet rod. A pair of symmetrical adjusting telescopic rods are provided at both ends of the adjusting beam, and both pairs of adjusting telescopic rods are movably connected to the mounting frame. The suspension rod is located below the adjusting beam, and the pair of blocking rollers are mounted on the suspension rod and movably engage with it.

[0004] By adopting the above technical solution, an auxiliary transmission device including a fan, connecting air duct, lower air outlet rod, adjusting beam, suspension rod, and a pair of blocking rollers is installed at the gap between the paper placement table and the conveyor belt. The lower air outlet rod blows air upward to prevent the part of the paper pushed out by the paper feeding mechanism from drooping under the action of gravity, thus avoiding the situation where the paper droops and then hits the conveyor belt, causing the paper to bend and bulge due to the speed mismatch between the paper and the conveyor belt. Furthermore, by setting up a pair of blocking rollers, when the part of the paper protruding from the air hole of the lower air outlet rod tends to bend upward, the pair of blocking rollers prevent the paper from bending excessively upward. At the same time, since the blocking rollers and the suspension rod can roll, the blocking rollers also have rolling contact with the paper surface, avoiding damage to the paper surface when blocking.

[0005] A further feature of this invention is that the adjusting beam is also provided with a pressing mechanism, which includes a fan, a connecting duct, a bend duct, and an upper outlet duct. The fan is mounted on the mounting frame, and the bend duct is mounted on the adjusting beam. One end of the bend duct is connected to the fan connecting cylinder through the connecting duct, and the other end is connected to the upper outlet duct. The bottom of the upper outlet duct has several air holes evenly distributed.

[0006] By adopting the above technical solution, since the adjusting beam is also equipped with a pressing mechanism, the pressing mechanism includes a fan, a connecting air duct, a folded air duct, and an upper air outlet duct. The fan is mounted on the mounting frame, and the folded air duct is mounted on the adjusting beam. One end of the folded air duct is connected to the fan connecting cylinder through the connecting air duct, and the other end is connected to the upper air outlet duct. The bottom of the upper air outlet duct has several air holes evenly opened. By blowing air downward through the upper air outlet duct, the paper can be directly and lightly attached to the surface of the conveyor belt after the extended part of the paper reaches the position of the conveyor belt. This avoids the situation where the paper touches the paper pressing mechanism on the conveyor belt when the paper is suspended in the air, which would cause the edges of the paper to be crushed or arched, thus further protecting the paper.

[0007] A further feature of this invention is that the angled duct and the upper exhaust duct are connected by a section of corrugated metal pipe.

[0008] By adopting the above technical solution, since the angled air duct and the upper air outlet duct are connected by a section of corrugated metal pipe, the air outlet angle of the upper air outlet duct can be adjusted according to the actual angle between the conveyor belt and the paper placement table.

[0009] A further feature of this invention is that the mounting bracket includes a base and a frame, and the frame and the base are tunably connected.

[0010] By adopting the above technical solution, since the mounting frame includes a base and a frame body, and the frame body and the base are adjustablely connected, the height of the mounting frame can be adjusted according to the installation height of the conveyor belt and the paper placement table, thereby improving the applicability of the auxiliary paper feeding device.

Detailed Implementation

[0015] like Figure 1-3 As shown, an auxiliary paper feeding device for a laminating machine's paper feeding mechanism includes a mounting frame 1 and an auxiliary transfer device 2. The mounting frame is disposed between the paper placement platform 3 and the conveyor belt 4 of the paper feeding mechanism. The auxiliary transfer device is disposed on the mounting frame and includes a fan 5, a connecting air duct 6, a lower air outlet rod 7, an adjusting beam 8, a suspension rod 9, and a pair of blocking rollers 10. The fan and the air outlet rod are both disposed on the mounting frame. The air outlet rod is located below the gap between the paper placement platform and the conveyor belt. The air outlet rod is connected to the fan via the connecting air duct. The top of the lower air outlet rod has several air holes 11 evenly distributed. The adjusting beam is disposed on the mounting frame and located above the air outlet rod. A pair of adjusting telescopic rods 12 are symmetrically provided at both ends of the adjusting beam. The pair of adjusting telescopic rods are movably connected to the mounting frame. The suspension rod is disposed below the adjusting beam. The pair of blocking rollers are disposed on the suspension rod and movably cooperate with the suspension rod.

[0016] An auxiliary conveying device, including a fan, connecting duct, lower air outlet rod, adjusting beam, suspension rod, and a pair of blocking rollers, is installed at the gap between the paper placement table and the conveyor belt. The lower air outlet rod blows air upwards to prevent the portion of the paper 19 pushed out by the paper feeding mechanism from drooping under gravity. This avoids the situation where the paper droops and then hits the conveyor belt, causing it to bend and bulge due to a mismatch between its speed and the conveyor belt's running speed. Furthermore, by installing a pair of blocking rollers, when the extended portion of the paper tends to bend upwards under the airflow from the air outlet of the lower air outlet rod, the blocking rollers prevent the paper from bending excessively upwards. At the same time, since the blocking rollers and the suspension rod can roll, the blocking rollers also make rolling contact with the paper surface, avoiding damage to the paper surface when blocking.

[0017] The adjusting beam is also provided with a pressing mechanism 13, which includes a fan, a connecting duct, a bend duct 14 and an upper outlet duct 15. The fan is mounted on the mounting frame, the bend duct is mounted on the adjusting beam, one end of the bend duct is connected to the fan connecting cylinder through the connecting duct, and the other end is connected to the upper outlet duct. The bottom of the upper outlet duct has several air holes evenly distributed.

[0018] Because the adjusting beam is also equipped with a pressing mechanism, the pressing mechanism includes a fan, a connecting air duct, a folded air duct, and an upper air outlet duct. The fan is mounted on the mounting frame, and the folded air duct is mounted on the adjusting beam. One end of the folded air duct is connected to the fan connecting cylinder through the connecting air duct, and the other end is connected to the upper air outlet duct. The bottom of the upper air outlet duct has several air holes evenly distributed. By blowing air downward through the upper air outlet duct, the paper can be directly and lightly placed on the surface of the conveyor belt after the extended part of the paper reaches the position of the conveyor belt. This avoids the situation where the paper touches the paper pressing mechanism on the conveyor belt when the paper is suspended in the air, which would cause the edges of the paper to be crushed or arched, thus further protecting the paper.

[0019] The angled duct and the upper air outlet duct are connected by a section of corrugated metal pipe 16.

[0020] Since the angled air duct and the upper air outlet duct are connected by a section of corrugated metal pipe, the air outlet angle of the upper air outlet duct can be adjusted according to the actual angle between the conveyor belt and the paper placement table.

[0021] The mounting bracket includes a base 17 and a frame 18, which are adjustablely connected to the base.

[0022] Since the mounting frame includes a base and a frame body, and the frame body is adjustablely connected to the base, the height of the mounting frame can be adjusted according to the installation height of the conveyor belt and the paper placement table, thereby improving the applicability of the auxiliary paper feeding device.
