A paper guide structure for reducing space

Abstract

The utility model discloses a paper guiding and avoiding structure of small space, which is characterized by comprising a paper feeding assembly, a paper table and a guide piece arranged at the back side of the paper table to avoid the collision and damage of paper during the backward movement of the paper after being rubbed by the rubber roller on the paper table, and to reduce the collision sound during the contact. The utility model adopts the height difference of paper feeding, and the next paper can be prepared in advance, which improves the production efficiency without increasing the length of the machine, the floor space and the manufacturing cost. Meanwhile, through the arrangement of the guide piece, the contact process of the paper tail end with the guide piece changes from point to line and then to surface during the backward movement of the paper, and the paper produces arc bending along the guide piece, thereby eliminating the impact sound during the backward movement of the paper and avoiding the damage of the paper and the influence on the cutting precision of the paper.

Description

Technical Field

[0001] This utility model relates to a die-cutting machine, specifically a paper guide and avoidance structure that reduces space requirements. Background Technology

[0002] Current digital die-cutting machines do not require molds. They use sensors to detect the beginning and end positions of the paper and CCD vision to recognize the image for numerical control die-cutting. Since the paper comes in different lengths, existing technologies typically employ two methods: 1. During paper cutting, the paper rolls back and forth above the paper table. This technology does not require lengthening the machine, but the next sheet cannot be prepared in advance. The next sheet can only be prepared after the previous sheet is cut. However, the vacuuming, blowing, and table lifting for the next sheet take 5-8 seconds, which greatly reduces production efficiency. 2. The distance between the paper feeding assembly and the rollers is extended according to the length of the paper. This technology limits the paper length to the distance between the paper feeding assembly and the rollers. Lengthening the space does not allow for the processing of shorter paper sizes, and it also greatly increases the machine's footprint and cost.

[0003] If a paper drop height difference is used without increasing the machine length, a baffle needs to be installed on the machine to block the previous sheet. After the end of the previous sheet passes the baffle, the paper feed sensor on the CNC die-cutting machine detects the end of the paper and drives the die-cutting machine's rubber roller to move the paper backward until the end of the paper is only held down by a single rubber roller before cutting begins. However, during this backward movement, even slightly thicker or harder sheets of paper will cause a significant impact noise when hitting the baffle, potentially damaging the paper and affecting cutting accuracy. Therefore, a space-saving paper guiding and avoidance structure is proposed. Utility Model Content

[0004] The purpose of this invention is to propose a space-saving paper guide and avoidance structure to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper guide and avoidance structure that reduces space, characterized by including a paper feeding assembly, a paper table, and a guide component disposed on the rear side of the paper table to prevent the paper from being damaged by collisions caused by friction during the backward movement of the rubber rollers on the paper table, while also reducing the collision noise during contact.

[0006] In a further preferred embodiment, the upper end of the guide is arc-shaped or inclined, so that when the tail end of the paper comes into contact with the guide, it guides the paper and causes the paper to move along the guide.

[0007] In a further preferred embodiment, the guide is inclined and forms an angle with the axis of the rubber roller, so that the paper contacts the guide during the backward movement, forming a contact process from point to line to surface, thereby reducing the impact noise generated when the paper contacts the guide.

[0008] A further preferred embodiment includes a paper guide disposed between the paper feeding assembly and the paper table, which serves to guide the paper feeding assembly when it is transported to the paper table.

[0009] A further preferred embodiment includes guide portions disposed at both ends of the paper guide to guide the paper onto the paper table and are arranged at an angle.

[0010] A further preferred embodiment includes an inclined portion disposed on the end of the guide portion on one side of the rubber roller, which guides the paper during its backward movement and prevents the paper from being interfered with by the guide portion.

[0011] The beneficial effects of this utility model are as follows: By using the height difference of the paper feeding device, the next sheet of paper can be prepared in advance, which improves production efficiency without increasing the length of the machine, the floor space, or the manufacturing cost. At the same time, by setting up the guide, the paper makes a point-to-line-to-surface contact process when the paper comes into contact with the guide at the end of the paper during the backward movement, and bends in an arc along the guide, thereby eliminating the impact noise generated during the backward movement of the paper, and preventing damage to the paper and affecting the accuracy of paper cutting.

[0014] The paper guide and avoidance structure for reducing space according to the present invention will be further described below with reference to the accompanying drawings.

[0015] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] See Figures 1-3 As shown, a space-saving paper guiding and avoidance structure is characterized by including a paper feeding assembly 1, a paper table 2, and a guide 4 disposed on the rear side of the paper table 2 to prevent the paper from being damaged by collision with the rubber roller on the paper table 2 during the frictional retraction process, while reducing the collision noise when in contact. The upper end of the guide 4 is arc-shaped or inclined so that when the tail end of the paper comes into contact with the guide 4, it guides the paper and makes the paper move along the guide 4. By using the height difference of the paper feeding device, the next sheet of paper can be prepared in advance, which improves production efficiency without increasing the length of the machine, the floor space, or the manufacturing cost. By setting the guide 4, and setting the upper end of the guide 4 in an arc shape or at an angle, the paper can bend in an arc shape along the guide 4 when the tail end of the paper contacts the guide 4 during the backward movement, so as to avoid damaging the paper and affecting the paper cutting accuracy during the backward movement.

[0018] In one embodiment, the guide 4 is inclined and forms an angle with the axis of the rubber roller, so that the paper contacts the guide 4 during the backward movement, forming a contact process from point to line to surface, thereby reducing the impact sound generated when the paper contacts the guide 4. By setting the guide 4 at an angle, there is an angle between the guide 4 and the axis of the rubber roller. This causes the contact between the tail end of the paper and the guide 4 during the paper's backward movement to change from point contact to line contact, then to surface contact, and finally to an arc-shaped bend along the guide 4. This eliminates the impact noise when the paper contacts the guide 4 during its backward movement, and also prevents damage to the paper and affects the accuracy of paper cutting.

[0019] In one embodiment, a paper guide 3 is provided between the paper feeding assembly 1 and the paper table 2 to guide the paper feeding assembly 1 to the paper table 2. By setting the paper guide 3, the paper is guided when it is fed to the paper table 2 through the paper feeding assembly 1.

[0020] In one embodiment, it further includes guide portions 31 disposed at both ends of the paper guide 3 to guide the paper to the paper table 2 and are inclined. Through the arrangement of the guide portions 31, the paper is contacted by the guide portions 31 when it is conveyed forward and is guided by the inclined guide portions 31.

[0021] In one embodiment, an inclined portion 32 is provided on the end of the guide portion 31 on one side of the rubber roller for guiding the paper during the backward movement and preventing the paper from being interfered with by the guide portion 31. By providing an upwardly curved inclined portion 32 on the guide portion 31 on the side of the rubber roller, the paper is guided during the paper retraction process, while avoiding interference with the paper retraction and preventing the paper from retracting normally.

[0022] When this utility model is in use: when the current sheet of paper is retracted by the friction of the rubber roller, the tail end of the paper first forms a point contact with the guide 4 during the retraction process. During the continuous retraction of the paper, the tail end of the paper bends in an arc along the guide 4. During this process, the contact between the tail end of the paper and the guide 4 changes from point contact to line contact, and then to surface contact. Then, when the paper is driven forward by the rubber roller and cut, the paper feeding assembly 1 can advance the next sheet of paper to the paper guide 3 to wait for the previous sheet to be cut.

[0023] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
