Description

Technical Field

[0001] The utility model relates to the technical field of semi - cured sheet cutting, in particular to a semi - cured sheet cutting device. Background Technique

[0002] The semi - cured sheet, also known as "PP sheet", is one of the main materials in the production of multi - layer boards. It is mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as fiberglass cloth, paper base, and composite materials. Most of the semi - cured sheets used in the production of multi - layer printed boards use fiberglass cloth as the reinforcing material. The fiberglass cloth after treatment is impregnated with resin glue, and then through heat treatment, the resin enters the B - stage to form a thin sheet material called semi - cured sheet, which is one of the main materials in the production of multi - layer boards. During the processing of semi - cured sheets, cutting operations need to be performed on the processing materials.

[0003] After retrieval, as disclosed in a Chinese patent document for a semi - cured sheet cutting device [Application No.: CN201922236514.8]. This semi - cured sheet cutting device includes a support mechanism and a cutting mechanism. A material mechanism is arranged on the left side of the support mechanism, and a guiding mechanism is arranged above the support mechanism. A cutting mechanism is arranged on the right side of the guiding mechanism. The cutting mechanism includes a pressure - bearing seat, a limiting cutting edge, a hob, a fixed seat, a limiting shaft, a threaded rod, and an electric shaft. A limiting cutting edge is arranged above the pressure - bearing seat, a hob is arranged above the limiting cutting edge, a limiting shaft is arranged inside the fixed seat, and an electric shaft is arranged at the rear end of the threaded rod.

[0004] When the device disclosed in this patent is in use, the semi - cured sheet can be guided and limited through the limiting panel, so that the semi - cured sheet will not easily have a large - amplitude position deviation during the movement. However, the position of the limiting panel is not adjustable, resulting in that when the device cuts semi - cured sheets of different sizes, the limiting panel cannot guide and limit the semi - cured sheet, reducing the applicability of the device during use;

[0005] At the same time, the device adjusts the tension of the semi - cured sheet through the guiding shaft to improve the accuracy of the cutting size of the semi - cured sheet. However, the position of the guiding shaft cannot be adjusted arbitrarily with the tension of the semi - cured sheet, resulting in a poor adjustment effect of the device on the tension of the semi - cured sheet and inaccurate cutting size of the semi - cured sheet.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figures 1-4As shown in the figure, a semi-cured sheet cutting device includes a frame 1. On one side of the frame 1, a feeding mechanism 2 is installed. The feeding mechanism 2 is used to limit the semi-cured sheet to be cut, so as to facilitate the subsequent cutting of the semi-cured sheet. On both sides of one side of the frame 1, support plates 3 are fixedly connected. On one side of the support plate 3, an adjustment mechanism 4 is installed. On one side of the support plate 3, a guide rod 5 is rotatably connected. Under this action, when moving the semi-cured sheet on the surface of the feeding mechanism 2, the semi-cured sheet can be unfolded under the action of the guide rod 5, so that the semi-cured sheet can be smoother. With the cooperation of the adjustment mechanism 4, the semi-cured sheet can be limited, so that the semi-cured sheet will not easily have a large position deviation during the movement, effectively improving the stability of the semi-cured sheet during movement, avoiding the instability of the semi-cured sheet during movement and affecting the accuracy of cutting the semi-cured sheet. Moreover, under the action of the adjustment mechanism 4, its position can be adjusted arbitrarily according to the size of the semi-cured sheet, so that the adjustment mechanism 4 can guide semi-cured sheets of different sizes, effectively improving the applicability of the device. The surface of the guide rod 5 is provided with scale lines 6. With the cooperation of the scale lines 6, the position of the adjustment mechanism 4 can be more accurate during movement, effectively improving the limiting effect on the semi-cured sheet. On both sides of the top of the frame 1, mounting brackets 7 are fixedly connected. On one side of the mounting bracket 7, a positioning groove 8 is opened. The inner cavity of the positioning groove 8 is slidably connected with a positioning block 9. The bottom of the positioning block 9 is fixedly connected with a compression spring 10. The other end of the compression spring 10 is fixedly connected with the inner wall of the positioning groove 8. On one side of the positioning block 9, an adjustment rod 11 is rotatably connected. Under the action of the adjustment rod 11, the semi-cured sheet can be guided. Moreover, with the cooperation of the compression spring 10 and the positioning block 9, the position of the adjustment rod 11 can be adjusted, so that the adjustment rod 11 can adjust the tension of the semi-cured sheet, so that the surface of the semi-cured sheet is smoother, avoiding the lack of tightness of the semi-cured sheet and affecting the accuracy during cutting. On one side of the mounting bracket 7, a cutting mechanism 12 is installed. The cutting mechanism 12 is composed of a servo motor, a threaded rod, a cutting knife and other structures. Under this action, it is convenient to cut the semi-cured sheet. A positioning rod 13 is fixedly connected to the inner cavity of the positioning groove 8. The other end of the positioning rod 13 penetrates to the other side of the positioning block 9 and is slidably connected with the inner wall of the penetration part. Under this action, the positioning block 9 can be guided when it moves, so that the positioning block 9 moves more stably during movement, avoiding the instability of the positioning block 9 during movement and affecting the adjustment of the tension of the semi-cured sheet by the adjustment rod 11. The positioning rod 13 is located inside the compression spring 10 and is used in cooperation with the compression spring 10. Under this action, the compression spring 10 can be guided during the compression or rebound process of the compression spring 10, so that the compression spring 10 is more stable during use, avoiding the instability of the compression spring 10 during movement and affecting the movement of the positioning block 9.

[0024] The adjustment mechanism 4 includes a bidirectional threaded rod 41 disposed on one side of the support plate 3. Both sides of the surface of the bidirectional threaded rod 41 are threadedly connected with sleeves 42. One side of the sleeve 42 is fixedly connected with a movable sleeve 43. The inner wall of the movable sleeve 43 is slidably connected with the surface of the guide rod 5. The movable sleeve 43 is used in cooperation with the scale line 6. Under this action, by rotating the bidirectional threaded rod 41, it can drive the two sleeves 42 to move in opposite or opposite directions simultaneously under the action of the surface threads, so that the movable sleeve 43 can be adjusted arbitrarily according to the size of the semi-cured sheet, effectively improving the applicability of the device. And with the cooperation of the guide rod 5, the movable sleeve 43 can be guided, so that its position will not be easily offset. And with the cooperation of the scale line 6, the position of the movable sleeve 43 can be more accurate when moving. One end of the bidirectional threaded rod 41 is fixedly connected with a bearing seat 14, and the other side of the bearing seat 14 is fixedly connected with one side of the support plate 3. Under this action, the bidirectional threaded rod 41 can be supported, so that the bidirectional threaded rod 41 can rotate more stably, avoiding the instability of the bidirectional threaded rod 41 during rotation and affecting the accuracy of the position of the movable sleeve 43 after movement.

[0025] It should be noted that: the technical features such as the frame 1, the feeding mechanism 2, and the cutting mechanism 12 proposed in this technical solution should be regarded as the technologies in the comparative cases. The specific structures, working principles, and possible control methods and spatial layout methods involved in these technical features can be selected conventionally in this field, and this technical solution will not be further specifically elaborated.

[0026] Working principle: First, install the semi-cured sheet to be cut on the surface of the feeding mechanism 2, then pull out the semi-cured sheet so that it contacts the surface of the guide rod 5, then move above the adjusting rod 11 and then move into the cutting mechanism 12. Immediately afterwards, the staff rotates the bidirectional threaded rod 41 to drive the sleeve 42 and the movable sleeve 43 to move under the action of the surface threads, so that the movable sleeve 43 limits the semi-cured sheet. And with the cooperation of the scale line 6, it can make the staff more accurate when adjusting the movable sleeve 43, effectively reducing the situation of the position offset of the semi-cured sheet. At the same time, with the cooperation of the compression spring 10 and the positioning block 9, the adjusting rod 11 can be driven to move, so that the adjusting rod 11 can push the semi-cured sheet upward. Under the action of the compression spring 10, the semi-cured sheet can always be in a taut state, avoiding the situation that the semi-cured sheet is too loose and affects the cutting accuracy.
