Description

Technical Field

[0001] The utility model relates to the technical field of paper pasting machines, in particular to a positioning structure for a high-speed paper pasting machine. Background Technique

[0002] The paper pasting machine belongs to the field of paper product manufacturing machinery. In particular, it is a paper pasting machine used for pasting two pieces of paper together. It is composed of a paper feeding mechanism, a paper pasting mechanism, and a paper pressing mechanism. Two air heads are arranged in parallel on the paper feeding mechanism. An intermediate positioning mechanism is arranged on the paper pasting mechanism, which divides the paper pasting mechanism into two paper feeding channels. Wing-shaped spring pieces are arranged on both sides of the paper pasting mechanism. The intermediate positioning mechanism is composed of an intermediate positioning guide block and a lifting mechanism. The structure is simple and the production efficiency is improved. During the paper pasting process of the paper pasting machine, in order to improve the paper pasting quality, it is necessary to center and position the face paper and the bottom cardboard and then press them together to align their edges. Therefore, during the operation of the paper pasting machine, such a positioning structure plays a very important role.

[0003] In view of this, Chinese Patent No. CN216300335U proposes a positioning structure for a high-speed paper pasting machine. The utility model greatly improves the positioning effect of the high-speed paper pasting machine during use, facilitates the transmission of paper, and improves the paper pasting efficiency of the paper. However, the existing positioning structures of paper pasting machines generally perform positioning during the paper transmission process. This positioning method still cannot ensure whether the papers are stacked and aligned during the paper pressing process. At the same time, when the paper is transmitted to the pressing area, due to its own weight, there is a certain inertial effect, which may cause it to deviate from the pressing area by a certain distance, resulting in skewed paper pasting and affecting the paper pasting quality. In response to this, a positioning structure for a high-speed paper pasting machine is proposed in this design scheme. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a positioning structure for a high-speed paper pasting machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model proposes a positioning structure for a high-speed paper pasting machine, including a transmission base and a positioning mechanism installed on the top of the transmission base;

[0006] The positioning mechanism includes a support backing plate installed at one end of the inner wall of the transmission base. At both ends on one side of the support backing plate, limit grooves are provided. First positioning bars are slidably arranged on the inner walls of the two limit grooves, and both sides of the two first positioning bars are in contact with both sides of the support backing plate respectively. An installation groove is provided on one side of the top of the support backing plate. A fixing plate is fixedly arranged on the inner wall of the installation groove. A first conveyor belt is installed on the inner wall of the installation groove. Chutes are provided on both sides at one end of the transmission base. A second positioning bar is inserted between the inner walls of the two chutes. Electric telescopic rods are fixedly arranged on one side of the inner walls of the two chutes, and the output ends of the two electric telescopic rods are fixedly connected to both sides of the second positioning bar respectively.

[0007] In one example, a bidirectional lead screw is rotatably arranged at the bottom of the inner wall of the transmission base where the support backing plate is located, and the outer walls at both ends of the bidirectional lead screw are respectively threadedly connected to the inner walls of the two first positioning bars.

[0008] In one example, a servo motor is installed at the bottom of the inner wall of the transmission base. Pulley wheels are fixedly arranged on the outer wall of the bidirectional lead screw and the output end of the servo motor respectively. A belt strip is provided for transmission between the outer walls of the two pulley wheels.

[0009] In one example, an installation bracket is fixedly arranged on one side of the second positioning bar. A pressure sensor is fixedly arranged on one side of the installation bracket, and the servo motor is electrically connected to the pressure sensor.

[0010] In one example, a contact shaft is inserted through one side of the second positioning bar, and one end of the contact shaft is in contact with one side of the pressure sensor. A second conveyor belt is installed at the other end of the inner wall of the transmission base.

[0011] In one example, a switch panel is fixedly arranged on one side of the transmission base, and the electric telescopic rods, the first conveyor belt, and the second conveyor belt are all electrically connected to an external power supply through the switch panel.

[0012] The positioning structure for a high-speed paper pasting machine proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For the positioning structure for a high-speed paper pasting machine, a positioning mechanism is arranged on the transmission base. The electric telescopic rod drives the second positioning bar to move in the chute to limit the front and rear positions of the paper. The position can be adjusted according to papers of different sizes to keep it centered front and back during pressing. When the paper presses against the second positioning bar, the servo motor is controlled by the pressure sensor to move the first positioning bar to press both sides of the paper to make it centered left and right and ensure that the papers are stacked neatly, so that the four peripheral edges will not shift after paper pasting, improving the quality of paper pasting.

Specific embodiments

[0020] In order to more clearly explain the overall concept of the present utility model, the following is a detailed description by way of example in conjunction with the attached drawings of the specification.

[0021] The embodiments are as follows:

[0022] The present utility model provides a positioning structure for a high-speed paper pasting machine as Figures 1-4 shown, including a transmission base 1 and a positioning mechanism 2 installed on the top of the transmission base 1;

[0023] The positioning mechanism 2 includes a support backing plate 201 installed at one end of the inner wall of the transmission base 1. Limiting grooves 202 are provided at both ends on one side of the support backing plate 201. First positioning bars 203 are slidably arranged on the inner walls of the two limiting grooves 202, and both sides of the two first positioning bars 203 are in contact with both sides of the support backing plate 201 respectively. An installation groove 204 is provided on one side of the top of the support backing plate 201. A fixed plate 205 is fixedly arranged on the inner wall of the installation groove 204. A first conveyor belt 206 is installed on the inner wall of the installation groove 204. Sliding grooves 207 are provided on both sides at one end of the transmission base 1. A second positioning bar 208 is inserted between the inner walls of the two sliding grooves 207. Electric telescopic rods 209 are fixedly arranged on one side of the inner walls of the two sliding grooves 207, and the output ends of the two electric telescopic rods 209 are fixedly connected to both sides of the second positioning bar 208 respectively. The second positioning bar 208 slides in the sliding groove 207 by the telescopic movement of the electric telescopic rod 209, mainly to adjust the position of the second positioning bar 208 according to the pressing of papers with different sizes and lengths, so that the paper remains centered front and back after being intercepted by it, and the top of the first conveyor belt 206 is just flush with the support backing plate 201. In the later stage, when pressing the paper, the paper will not sink into the installation groove 204 due to the support of the fixed plate 205, preventing indentations from appearing on the pressed paper, and the surface friction coefficient of the first conveyor belt 206 is sufficient, and the paper will be driven and conveyed when it contacts it;

[0024] Further, a bidirectional lead screw 210 is rotatably arranged at the bottom of the inner wall of the transmission base 1 where the support backing plate 201 is located, and the outer walls of both ends of the bidirectional lead screw 210 are respectively threadedly connected to the inner walls of the two first positioning bars 203.

[0025] A servo motor 211 is installed at the bottom of the inner wall of the transmission base 1. Pulley wheels 212 are fixedly arranged on the outer wall of the bidirectional lead screw 210 and the output end of the servo motor 211 respectively. A belt strip 213 is provided for transmission between the outer walls of the two pulley wheels 212, and one end of the first positioning bar 203 is in contact with the bottom of the support backing plate 201. Through the threaded connection with the bidirectional lead screw 210, the first positioning bars 203 can be passively moved closer to or away from each other after the servo motor 211 is started;

[0026] Further, an installation bracket 3 is fixedly arranged on one side of the second positioning bar 208. A pressure sensor 4 is fixedly arranged on one side of the installation bracket 3, and the servo motor 211 is electrically connected to the pressure sensor 4.

[0027] A contact shaft 5 is inserted through one side of the second positioning bar 208, and one end of the contact shaft 5 is in contact with one side of the pressure sensor 4. A second conveyor belt 6 is installed at the other end of the inner wall of the transmission base 1. Once the paper conveyed by the first conveyor belt 206 contacts the contact shaft 5, the pressure received by the pressure sensor 4 can be increased, and the servo motor 211 can be driven immediately, and then the first positioning bar 203 can be driven to move and position.

[0028] Working principle: When using the positioning structure for the high-speed paper mounting machine in this design solution, first, the paper for paper mounting is conveyed to the support backing plate 201 through the second conveyor belt 6 and waits for lamination. Before lamination, centering positioning is performed through the positioning mechanism 2. After the paper is conveyed from the second conveyor belt 6 to the support backing plate 201, it continues to be conveyed by contacting the first conveyor belt 206 in the mounting groove 204 until it is blocked by the second positioning strip 208 and cannot move forward. When contacting the second positioning strip 208, it will squeeze the contact shaft 5, which in turn squeezes the pressure sensor 4 on the mounting bracket 3, thereby starting the servo motor 211. The bidirectional lead screw 210 is driven to rotate in conjunction with the pulley 212 and the belt 213. The bidirectional lead screw 210 drives the first positioning strips 203 at both side edges of the support backing plate 201 to move closer to the center and squeeze the paper to push it to the center position in the lamination area, enabling the paper for paper mounting to be centered horizontally through the first positioning strip 203 and centered front and back through the blocking of the second positioning strip 208 in the lamination area. It can ensure that when paper mounting, the paper is not only centered but also kept flush with each other, improving the quality of paper mounting.
