Description

Technical Field

[0001] The utility model relates to a PEUD cloth trimming tool. Background Art

[0002] PEUD cloth is a high-performance fiber material widely used in composite materials and structural reinforcement fields. Its production and processing require extremely high precision and consistency. During the trimming process, traditional cutting equipment usually uses manual operation or hot cutting knives to trim the cloth, but these methods expose multiple defects in modern high-demand production environments.

[0003] Existing manual trimming equipment relies on manual adjustment of the fabric position. The left and right positions of the reels are difficult to control accurately, resulting in misalignment of the two sides of the fabric during winding, which ultimately affects the quality of the finished product. This is especially true when multiple rolls of UD fabric are processed simultaneously. The problem of left-right misalignment is more prominent, which not only makes it impossible to guarantee trimming accuracy, but also increases the scrap rate and reduces production efficiency.

[0004] Traditional hot knife trimming equipment has the disadvantages of high energy consumption and uneven cutting. Hot knives cut fabric by heating the blade. Although they can complete trimming, the operation process imposes large thermal stress on the fabric, which can easily cause material damage. At the same time, the operation is complicated and requires the operator to have a high level of technical skills. More importantly, there are high safety risks when operating hot knives, especially when cutting under high temperature conditions. The high degree of manual participation poses a potential risk of burns and equipment failure.

[0005] Therefore, those skilled in the art urgently need a PEUD cloth trimming tool with high trimming quality and production efficiency and high degree of automation. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the above-mentioned existing technologies and provide a PEUD fabric trimming tool that is highly precise, easy to operate, and highly automated. By combining left and right limiters with a photoelectric correction device, this tool solves the inaccuracy, high energy consumption, and low safety issues associated with traditional manual operation and hot-cutting equipment during the trimming process, achieving automated and efficient production of multi-roll UD fabric trimming. The following is a specific solution:

[0007] A PEUD cloth trimming tool comprises at least two oppositely arranged frames and at least three pneumatic shafts, the frames being provided with positioning holes, a main mounting seat and a secondary mounting seat, the pneumatic shafts being passed through the positioning holes, the pneumatic shafts being arranged on the frames through the main mounting seat and the secondary mounting seat, the main mounting seat being respectively provided with a pressing block in the horizontal direction and the vertical direction, the pressing blocks being both movable in the inward direction, one end of the pressing block being in contact with the main mounting seat, the other end of the pressing block being provided with a handle, the handles being connected to a motor control module, the outer surface of the pneumatic shaft being circumferentially provided with scale lines, the extension direction of the scale lines being horizontal, a level ruler corresponding to the scale lines being provided in the frame, the level ruler comprising an optical sensing device, and the optical sensing device being electrically connected to the motor control module.

[0008] The pneumatic shaft is fixed to the frame through the main mounting seat and the auxiliary mounting seat, which ensures the stability of the fabric reel during the trimming process. The pneumatic shaft is accurately positioned through the positioning hole. The outer surface of the pneumatic shaft is provided with scale lines. The spirit level and its optical sensing device can read the position changes of the scale lines, so as to detect and adjust the fabric position in real time to ensure high precision during fabric trimming; the top pressure blocks are respectively arranged in the horizontal and vertical directions of the main mounting seat, and can move inward. The movement of the top pressure blocks is controlled by the motor control module, and the pressure of the top pressure blocks can be adjusted according to the thickness and position of the fabric to ensure that the fabric is always in the best condition during the trimming process. The advantage of this setting is that it can automatically adapt to fabrics of different specifications and widths, thereby improving the applicability and operational flexibility of the equipment.

[0009] The spirit level cooperates with the scale lines on the inflatable shaft. The optical sensing device on the spirit level can read the position information of the scale lines in real time and transmit the data to the motor control module. The motor control module automatically adjusts the angle and position of the inflatable shaft based on this data. This automated design avoids the errors caused by manual adjustment and ensures high-precision alignment of the fabric during the trimming process. At the same time, it greatly improves production efficiency and reduces operational difficulty and labor intensity.

[0010] Furthermore, both ends of the inflatable shaft are provided with limit blocks, which are used to fix the cloth rolling position to prevent the cloth from moving axially during the trimming process, thereby further ensuring the alignment and trimming accuracy of the cloth.

[0011] Furthermore, the height of the frame is 2-3m, and there are three inflatable shafts. The distance between the inflatable shafts is 0.7-1m. Setting three inflatable shafts can accommodate and process multiple rolls of PE UD cloth at the same time, greatly improving the trimming efficiency and adapting to large-scale production needs. The spacing between the inflatable shafts allows the cloth to be unfolded smoothly without interfering with each other.

[0012] Furthermore, the length of the inflatable shaft is 1-1.3m.

[0013] Furthermore, the frame is provided with a receiving groove, and the top pressure block is arranged in the receiving groove. The frame is provided with a receiving groove, and the top pressure block is arranged in the receiving groove, which can prevent the top pressure block from being offset due to external force during operation. The adjustment rod in the receiving groove moves through the through hole, allowing the operator to adjust the position of the top pressure block as needed, thereby further improving the trimming accuracy. This design ensures the stability and flexibility of the cloth during the trimming process and adapts to a variety of working environments and needs.

[0014] Furthermore, a pressure cover is provided on the top of the frame, which is used to fix and protect the inflatable shaft, ensure that the shaft does not move or vibrate when rotating at high speed, and maintain the overall stability of the device.

[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0025] A PEUD cloth trimming tool comprises at least two oppositely arranged frames 1 and at least three pneumatic shafts 2. The frame 1 is provided with a positioning hole 6, a main mounting seat 3 and a secondary mounting seat 4. The pneumatic shaft 2 is passed through the positioning hole 6. The pneumatic shaft 2 is arranged on the frame 1 through the main mounting seat 3 and the secondary mounting seat 4. A top pressure block 11 is respectively provided in the horizontal direction and the vertical direction of the main mounting seat 3. The top pressure block 11 can be moved inward. One end of the top pressure block 11 contacts the main mounting seat 3, and the other end of the top pressure block 11 is provided with a handle 7. The handles 7 are all connected to the motor control module. The outer surface of the pneumatic shaft 2 is circumferentially provided with scale lines 9, and the extension direction of the scale lines 9 is horizontal. A level ruler 13 corresponding to the scale lines 9 is provided in the frame 1. The level ruler 13 includes an optical sensing device, and the optical sensing device is electrically connected to the motor control module.

[0026] Both ends of the inflatable shaft 2 are provided with limit blocks. The height of the frame 1 is 2-3m, and there are three inflatable shafts 2. The distance between the inflatable shafts 2 is 0.7-1m, and the length of the inflatable shaft 2 is 1-1.3m. The frame 1 is provided with a accommodating groove 10, and the top pressure block 11 is arranged in the accommodating groove 10. The top pressure block 11 also includes an adjusting rod 12, and the accommodating groove 10 also includes a through hole. The adjusting rod 12 can move in the through hole. The top of the frame 1 is provided with a pressure cover 5, the diameter of the positioning hole 6 is 8cm, and the diameter of the inflatable shaft 2 is 5cm.

[0027] For the purpose of greater clarity, the present invention is described in detail with reference to the following examples.

[0028] The frame 1 is made of high-strength carbon steel and is sprayed with anti-rust paint on the surface to ensure that it is not easily corroded in a long-term working environment. The frame 1 is 2 meters high and 1.5 meters wide, which can stably support the entire trimming device. The frame 1 includes two oppositely arranged support columns, each of which is provided with multiple positioning holes 6 for the inflatable shaft 2, with a hole diameter of 8 cm, which is convenient for the installation of the inflatable shaft 2.

[0029] The inflatable shaft 2 is made of 6061-T6 aluminum alloy, which is lightweight, high-strength and corrosion-resistant, ensuring stability during high-speed operation. The tooling is equipped with three inflatable shafts 2, each of which is 1.2 meters long and 5 centimeters in diameter. There are horizontal scale lines 9 on the circumference. The scale lines 9 are formed by laser etching to ensure that they will not wear out during long-term use. The inflatable shaft 2 is used to install PE UD cloth rolls. Limit blocks are provided at both ends of each shaft. The limit blocks are made of highly wear-resistant plastic to ensure the stability of the cloth roll during the trimming process and prevent axial movement of the cloth.

[0030] The main mounting seat 3 and the auxiliary mounting seat 4 are both made of stainless steel with strong corrosion resistance and high strength, ensuring that they are not easily deformed during operation. The main mounting seat 3 and the auxiliary mounting seat 4 are fixed to the frame 1 by bolts to form a stable support structure. The main mounting seat 3 is provided with a top pressure block 11 in the horizontal direction and the vertical direction respectively. The top pressure block 11 is made of polyamide plastic with excellent wear resistance and self-lubricating properties, reducing the friction loss between the inflatable shaft 2 and the top pressure block 11.

[0031] One end of the top pressure block 11 is in contact with the main mounting seat 3, and the other end is connected to the motor control module through the handle 7. An elastic gasket is provided in the top pressure block 11, which can be fine-tuned through the adjustment rod 12 to adapt to fabrics of different thicknesses. The adjustment rod 12 is moved through a through hole provided in the accommodating groove 10. The diameter of the through hole is 1.5 cm, ensuring that the adjustment rod 12 can move smoothly. The motor control module drives the top pressure block 11 to move along the inner direction through the handle 7 to ensure that the fabric remains in close contact and does not deviate during trimming.

[0032] The optical sensing device's housing is made of high-heat-resistant glass, housing a high-precision photoelectric sensor. The motor control module is driven by a stepper motor and includes a built-in microcontroller unit for receiving feedback signals from the optical sensing device. The optical sensing device is mounted on a level 13 and is used to read the scale lines 9 on the inflatable shaft 2. The optical sensing device is connected to the motor control module. When fabric deviation is detected, the motor control module automatically adjusts the position and angle of the inflatable shaft 2 to ensure trimming accuracy. The level 13 is made of a carbon fiber composite material, offering lightweight, high rigidity, and a low coefficient of thermal expansion, ensuring measurement accuracy under varying temperature conditions. The level 13 is positioned along the extension direction of the inflatable shaft 2 and aligns with the horizontal scale lines 9 on the shaft. The optical sensing device monitors the status of the shaft 2 in real time. In general, the optical sensing device detects the difference between the level 13 and the scale lines 9, and automatically controls the orientation of the inflatable shaft 2 based on this difference.

[0033] The following is a specific implementation method:

[0034] Install the PE UD fabric roll to be trimmed on the air shaft 2, ensuring that the center of the fabric is aligned with the center of the air shaft 2. The limit blocks on both sides lock the fabric roll to prevent it from axial movement during rotation. By adjusting the limit devices, it can adapt to fabrics of different widths.

[0035] According to the thickness of the fabric, the operator fine-tunes the pressure of the pressing block 11 through the motor control module. The pressing block 11 automatically moves along the inner side through the motor control module to ensure close contact between the fabric and the inflatable shaft 2. At the same time, the optical sensing device of the level 13 starts to read the scale line 9 on the inflatable shaft 2 to monitor the alignment status of the fabric in real time.

[0036] After the trimming equipment is started, the pneumatic shaft 2 begins to rotate, and the PEUD fabric roll is also unrolled. The optical sensing device detects the position of the scale line 9 and feeds back the deviation data of the fabric position to the motor control module. The motor control module automatically adjusts the position of the pneumatic shaft 2 according to the feedback signal to ensure that the fabric always remains horizontal and aligned during the trimming process.

[0037] During the trimming process, the top pressure block 11 maintains a stable pressure to ensure that the cloth is tightly attached to the inflatable shaft 2. The automatic control system makes fine adjustments based on the feedback information from the optical sensing device to achieve trimming of the cloth.

[0038] After the trimming work is completed, the air shaft 2 stops rotating, and the operator can loosen the limit block, unload the trimmed cloth roll, and prepare to trim the next roll of cloth.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
