Description

Technical Field

[0001] This utility model relates to the field of glass fiber mat cutting technology, and more specifically, to a glass fiber mat cutting machine. Background Technology

[0002] In both industrial and manual production of fiberglass mat, the cutting process faces numerous significant challenges that urgently need to be addressed. Fiberglass mat, a flexible material composed of continuous glass fibers interwoven randomly and without orientation, is soft and possesses a certain degree of elasticity and extensibility. This characteristic makes it highly susceptible to slack during cutting. Once the fiberglass mat is in a slack state, the cutting process becomes extremely difficult.

[0003] During actual cutting operations, loose fiberglass mats are prone to wrinkling. When the cutting tool contacts these wrinkles, it not only damages the original structure of the fiberglass mat but also causes the cutting path to deviate from the pre-set trajectory. Furthermore, due to the lack of effective fixing and tension, the fiberglass mat is highly susceptible to shifting during cutting, making precise control of the cutting position difficult. This shift not only leads to dimensional deviations, resulting in fiberglass mat products that do not meet specifications, but also wastes material. More seriously, these problems ultimately result in uneven cut surfaces, significantly impacting the quality of fiberglass mat products. For applications with high precision and surface quality requirements, such as aerospace and automotive manufacturing, uneven cut surfaces can render products unusable, affecting the efficiency of the entire production process and product performance, increasing production costs and timelines. Moreover, under traditional cutting methods, operators need to spend considerable time and effort adjusting the position of the fiberglass mat to ensure cutting accuracy, which undoubtedly reduces production efficiency and limits the development of the fiberglass mat processing industry.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a glass fiber mat cutting machine. Utility Model Content

[0005] The purpose of this invention is to provide a glass fiber mat cutting machine to solve the problems mentioned in the background art.

[0007] A second cutter is provided on the base corresponding to the position of the first cutter, and a pad A and a pad B are provided on the base corresponding to the position of the second cutter. The pad A and the pad B are symmetrically arranged corresponding to the position of the second cutter.

[0008] Multiple tensioning mechanisms are symmetrically arranged on both sides of the first cutter. Each tensioning mechanism is arranged corresponding to the position of pad A and pad B. Each tensioning mechanism includes a support rod and a tensioning element. Each support rod is rotatably connected to one side of the first cutter, and a torsion spring is installed between each support rod and the first cutter. The torsion spring can provide a supporting force to the support rod. In the static state, the support rod will form a certain angle with the first cutter due to the elastic force of the torsion spring.

[0009] Preferably, the tensioning mechanism is further provided with an adjustment mechanism, which includes a movable block, a threaded groove, a guide groove, a screw, and a knob;

[0010] Each of the support rods has a guide groove, and each support rod is rotatably connected to a screw. One end of the screw extends into the guide groove, and the other end of the screw is provided with a knob. Here, the screw can be rotatably mounted on the support rod through a bearing.

[0011] Preferably, the bearing seat and the first cutter are rotatably connected via a hinge mechanism.

[0012] Preferably, the first cutter is provided with a handle.

[0013] Preferably, the tensioning element is a roller, each roller surface is covered with a rubber layer, and the surfaces of pad A and pad B are provided with rubber layers.

[0014] Compared with the prior art, the beneficial effects of this utility model are: through the unique tensioning mechanism design, the tensioning element is used to stretch the loose glass fiber mat from both ends during the cutting process, so that it fits tightly against the pad, effectively avoiding problems such as wrinkles and displacement caused by the loose glass fiber mat, ensuring a smooth cutting process, and significantly improving the flatness of the cutting surface and the cutting quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides an embodiment of a fiberglass mat cutting machine. This device is mainly used for cutting fiberglass mat. In actual industrial production or related manual operation scenarios, fiberglass mat cutting often encounters problems such as loose fiberglass mat, leading to cutting difficulties and poor cutting results. The emergence of this device can effectively solve the problem of loose fiberglass mat making cutting difficult, and it also has the function of flexibly adjusting for different types and thicknesses of fiberglass mat, greatly improving the efficiency and quality of cutting operations. The following is a detailed implementation of the device:

[0022] The device mainly consists of a base 1, a bearing 4, a first cutter 5, a second cutter 6, a pad A2, a pad B3, and a tensioning mechanism 8. The base 1, as the fundamental support component of the entire device, plays a crucial role in stabilizing it. It needs to possess a certain weight and stability to ensure that the device will not shake or shift due to external forces during the cutting process, thus guaranteeing cutting accuracy and safety. The bearing 4 is fixed to the base 1, and the first cutter 5 is rotatably connected to the bearing 4. The bearing 4 and the first cutter 5 are connected by a hinge mechanism, which generally consists of a pin and two rods with holes. The pin passes through the holes in the two rods, connecting them together, allowing the two rods to rotate relative to each other around the pin's axis. This connection method cleverly achieves the flexible rotation of the first cutter 5 on the bearing 4, providing the necessary conditions for subsequent cutting operations.

[0023] On the base 1, a second cutter 6 is positioned corresponding to the first cutter 5. The first cutter 5 and the second cutter 6 work together to cut the fiberglass mat. Pads A and B are positioned symmetrically about the second cutter 6, corresponding to the second cutter 6. Both pads A and B have a rubber layer on their surfaces, a design of significant importance. The rubber layer provides high friction, effectively reducing the risk of the fiberglass mat slipping on pads A and B. During cutting, slippage of the fiberglass mat can lead to deviation in the cutting position, inaccurate cutting dimensions, and even damage to the fiberglass mat. The rubber layer provides a stable "resting place" for the fiberglass mat, allowing it to stay firmly on the pads and creating favorable conditions for precise cutting.

[0024] The first cutting blade 5 is equipped with multiple tensioning mechanisms 8, which are symmetrically arranged on both sides of the first cutting blade. Each tensioning mechanism 8 is positioned corresponding to the positions of the pad A2 and the pad B3. Each tensioning mechanism 8 includes a support rod 81 and a tensioning element 82. Each support rod 81 is rotatably connected to one side of the first cutting blade 5, and a torsion spring is installed between each support rod 81 and the first cutting blade 5. Figure 1 As shown, in a stationary state, the torsion spring causes the support rod 81 to form an angle with the first cutter 5, and the end of the support rod 81 away from the first cutter 5 is closer to the base 1 than the end of the support rod 81 that is closer to the first cutter 5.

[0025] Each support rod 81 is rotatably connected to the first cutter 5 by a hinge. This hinge allows the support rod 81 to rotate freely within a certain range, providing flexibility for subsequent tensioning actions.

[0026] In use, the fiberglass mat is placed on pads A2 and B3, and the first cutter 5 is pressed down, at which point the tensioning element 82 comes into contact with the fiberglass mat. As the first cutter 5 continues to descend, the tensioning element 82, under the reaction force of pads A2 and B3 and the driving force of the first cutter 5, will cause the support rod 81 to rotate based on the first cutter 5. At this time, the support rod 81 will compress the torsion spring, and the torsion spring will accumulate elastic force. This process will continue until the first cutter 5 finishes cutting the fiberglass mat, or until the support rod 81 is flush with the first cutter 5. During this process, the tensioning element 82 will slide on pads A and B, thereby stretching the fiberglass mat laid on pads A2 and B3 from both ends, making the fiberglass mat taut. Imagine that the originally loose fiberglass mat is like a soft, limp piece of cloth, which is gradually stretched and tightened under the action of the tensioning element 82, becoming flat and firm. In this way, the fiberglass mat can adhere tightly to the pad, facilitating cutting by the first cutter 5 and the second cutter 6, and avoiding the problem of loose fiberglass mats hindering cutting. If the fiberglass mat is loose, wrinkles and misalignment are likely to occur during cutting, resulting in an uneven cut surface and significantly reduced cutting quality. However, by tensioning the fiberglass mat through the tensioning mechanism 8, the cutting process becomes smoother, and the cutting effect is significantly improved.

[0027] Considering the varying widths of the fiberglass mat, multiple tensioning mechanisms 8 are typically evenly arranged on the first cutter 5 to achieve better tensioning. As the first cutter 5 moves, the tensioning mechanisms 8 tension the fiberglass mat sequentially, thereby achieving a better cutting effect.

[0028] Considering the varying thicknesses of different types of fiberglass mats, an adjustment mechanism 9 is incorporated into the tensioning mechanism 8 to allow for tension adjustment. The adjustment mechanism 9 includes a movable block 91, a threaded groove 92, a guide groove 93, a screw 94, and a knob 95. The guide groove 93 is formed on the support rod 81, and the screw 94 is rotatably connected to the support rod 81. One end of the screw 94 extends into the guide groove 93, and the other end is fitted with the knob 95. The tensioning element 82 has a movable block 91 with a threaded groove 92 threadedly connected to the screw 94. The movable block 91 is slidably connected within the guide groove 93. By rotating the knob 95, the screw 94 rotates, causing relative movement between the tensioning element 82 and the movable rod, thereby adjusting the distance between the tensioning element 82 and the support rod 81. This adjustable design is highly practical because different types and thicknesses of fiberglass mats require different levels of tension. For thicker fiberglass mats, the distance between the tensioner 82 and the support rod 81 may need to be increased to generate greater tension; while for thinner fiberglass mats, the distance can be decreased to avoid over-tensioning and damage to the fiberglass mat. Through this targeted adjustment, the device can be applied to various types and thicknesses of fiberglass mats, greatly improving its versatility and applicability.

[0029] To facilitate operation of the first cutter 5, a handle 7 is provided on it. The handle 7 is designed with ergonomic principles in mind; its shape, size, and position are carefully considered, allowing the operator to perform cutting actions more conveniently and comfortably. By gripping the handle 7, the operator can easily control the descent and ascent of the first cutter 5, improving operational convenience and efficiency.

[0030] The tensioning element 82 can be configured as a slider that can slide on the pads A2 and B3 where the fiberglass mat is laid.

[0031] In addition, for some fiberglass mats with relatively rough surfaces, to facilitate the sliding of the tensioning element 82 on the surface of the fiberglass mat and prevent tearing, the tensioning element 82 can be set as a roller, and each roller surface is covered with a rubber layer. The presence of rollers changes the contact mode between the tensioning element 82 and the fiberglass mat from sliding friction to rolling friction, greatly reducing the frictional force and allowing the tensioning element 82 to slide more smoothly on the surface of the fiberglass mat. The rubber layer on the roller surface further increases the frictional force between the roller and the fiberglass mat, reducing the risk of slippage when the roller moves and ensuring the smooth operation of the tensioning action. In addition, in some cases, a resistance torque can be set between the roller and the support rod 81 to increase the frictional force received by the roller when it rotates.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
