Technical Field

[0001] This application relates to the field of PP cutting technology, and specifically discloses a double-roll PP sheet stacking device. Background Technology

[0002] Prepreg, composed of resin and reinforcing materials, is used as a dielectric and adhesive material in multilayer board production. It softens under heat and pressure, and cures upon cooling, becoming a conductive material that connects circuit layers. With the trend towards miniaturization and high performance in electronic devices, the precision and quality requirements for multilayer boards are constantly increasing, necessitating the precise cutting of prepreg to meet the production needs of circuit boards of different sizes and shapes.

[0003] Existing cutting equipment is mostly single-roll cutting, which is obviously insufficient in practical use. It has low production efficiency and low cutting accuracy, and cannot meet people's needs. In view of the above, this application provides a double-roll PP sheet stacking equipment.

[0026] Example

[0027] To address the issues of low efficiency and low cutting accuracy in existing single-roll cutting equipment for PP, this paper refers to... Figure 1 As shown, this application discloses a double-roll PP sheet stacking device, including a feeding mechanism 10, a picking mechanism 20, a cutting mechanism 30 and a stacking mechanism 40;

[0028] The feeding mechanism 10 includes a first unwinding unit 11 and a second unwinding unit 12 arranged side by side along a first direction for releasing PP material. In actual implementation, the first unwinding unit 11 and the second unwinding unit 12 release PP material respectively and stack them together to be picked up by the picking mechanism 20.

[0029] The feeding mechanism 20 includes a body 21 located at the rear end of the second unwinding unit 12, an upper feeding wheel 23 located inside the upper part of the body 21 and driven to rise by the first lifting drive unit 22, and a lower feeding wheel 25 located inside the lower part of the body 21 and driven to rotate by the rotary drive unit 24. When the feeding head is being fed, the first lifting drive unit 22 drives the upper feeding wheel 23 to rise. At this time, the operator can pass the head of the PP material through the upper feeding wheel 23 and the lower feeding wheel 25. During actual feeding, the rotary drive unit 24 rotates the lower feeding wheel 25. At this time, the lower feeding wheel 25 cooperates with the upper feeding wheel 23 to pull out a set length of PP material.

[0030] The cutting mechanism 30 includes an upper guillotine 32 located above the interior of the machine body 21 at the rear end of the feeding mechanism 20 and driven to rise and fall by the second lifting drive unit 31, and a lower guillotine 33 located below the interior of the machine body 21. When the lower feeding wheel 25 and the upper feeding wheel 23 pull out a PP material of a set length, the second lifting drive unit 31 will drive the upper guillotine 32 to descend, and the PP material can be cut in cooperation with the lower guillotine 33.

[0031] The stacking mechanism 40 includes a lifting stacking platform 41 located at the rear of the machine body 21. When the PP material is cut, the operator can help pull the PP material onto the lifting stacking platform 41 for stacking. Each time the PP material is stacked, the lifting stacking platform 41 will be lowered to a set height to facilitate subsequent stacking work.

[0032] In addition to the above-mentioned structure, this application also includes a tension control unit 13. The tension control unit 13 includes two tension wheels 131 respectively located at the front of the machine body 21 for tension control of the PP material released by the first unwinding unit 11 and the second unwinding unit 12, and guide wheels 14 respectively located at the front of the machine body 21 below the two tension wheels 131 for guiding the PP material. After the first unwinding unit 11 and the second unwinding unit 12 release the PP material, it will be guided by the guide wheels 14 and then pass around the tension wheels 131. In this way, the tension of the PP can be kept constant during the cutting process, thus improving the cutting accuracy.

[0033] In one specific embodiment, the first unwinding unit 11 and the second unwinding unit 12 of this application respectively include a feeding rack 111, an air shaft 112 rotatably mounted on the feeding rack 111, and a magnetic powder brake 113 mounted on the air shaft 112 for controlling its rotation. In actual use, a PP unwinding drum is first fixedly mounted on each air shaft 112, and the magnetic powder brake 113 can control the air shaft 112 to stop rotating, thereby ensuring that the lead-out mechanism can lead out a set length of PP material each time.

[0034] In one specific embodiment, the first lifting drive unit 22 of this application consists of a cylinder 221 and a bracket 222. The upper feed wheel 23 is mounted on the machine body 21 via the bracket 222. The piston rod of the cylinder 221 is connected to the bracket 222. In a specific implementation, the cylinder 221 drives the bracket 222 to rise, and the upper feed wheel 23 can leave a gap with the upper and lower feed wheels 25, so that the operator can perform the feeding head operation.

[0035] In one specific embodiment, the rotary drive unit 24 of this application includes a first servo motor 241 disposed on the body 21 and connected to the lower traction wheel. Under the drive of the first servo motor 241, the lower traction wheel of this application can cooperate with the upper traction wheel to lead out a PP material of a set length.

[0036] In one specific embodiment, the second lifting drive unit 31 of this application includes a second servo motor 311, a cam 312 and a connecting rod 313. The second servo motor 311 is mounted on the machine body 21 and is connected to the upper guillotine 32 through the cooperation of the cam 312 and the connecting rod 313. The second servo motor 311 can drive the upper guillotine 32 to descend through the cooperation of the cam 312 and the connecting rod 313. When it cooperates with the lower guillotine 33, it can cut PP material.

[0037] As an example, the lifting and stacking platform 41 of this application is an electric lifting platform. In addition, in actual use, those skilled in the art can also choose other types of lifting and stacking platforms 41, such as hydraulic lifting platforms or pneumatic lifting platforms. The specific structure will not be described in detail here.
