Description

Technical Field

[0001] This utility model relates to the technical field of strip die-cutting, and in particular to a device for precise tension control and synchronous feeding of foam materials for continuous die-cutting. Background Technology

[0002] Die-cutting is a processing technology that refers to the process of using a punch press or die-cutting machine to precisely indent and cut raw materials with molds or cutters to form parts of a specific shape; foam material is a porous elastic material made of plastic particles. It has the characteristics of high resilience, light weight, softness, ease of use, flexibility, ultra-thin size, and reliable performance. It is widely used in shock absorption, sealing, gap filling, packaging, sound insulation, heat insulation and other fields.

[0003] The existing Chinese utility model patent with application number CN202322704989.1 relates to a substrate-free foam material die-cutting device, including a material belt rotary drum, a die-cutting machine, a receiving rotary drum, a guide shaft, an auxiliary conveying component, a guide shaft and a conveyor belt, which can effectively improve defects such as size, deformation and bending, and greatly improve the product yield.

[0004] However, in actual use, the cutting area of ​​the device is deformed by pressure during the cutting process, resulting in insufficient flatness of the cut surface, which affects the quality of the product in subsequent use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a foam material tension precision control and synchronous feeding device for continuous die-cutting foam material. The device uses a feeding device to transport and fix foam, and an adjusting device to assist in squeezing the foam cutting area in conjunction with the feeding device. This keeps the foam in the cutting area flat during the fixing process, improves the cutting effect of the cutting device, and improves the practicality of the device by cutting the foam.

[0006] This utility model discloses a precision tension control and synchronous feeding device for continuous die-cutting foam materials; it includes a feeding device, an adjusting device, and a cutting device. The adjusting device is installed on the feeding device, and the cutting device is installed on the feeding device. The feeding device transports and fixes the foam, and the adjusting device, in conjunction with the feeding device, assists in squeezing the foam cutting area, thereby keeping the foam in the cutting area flat during the fixing process, improving the cutting effect of the cutting device, and improving the practicality of the device by cutting the foam.

[0007] Preferably, the feeding device includes a conveyor frame, conveyor rollers, a conveyor belt, a drive motor, a gantry, a first electric cylinder, and a pressure plate. Multiple sets of conveyor rollers are installed on the conveyor frame, and the conveyor belt is fitted onto these rollers. A drive motor is installed on the side of the conveyor frame, and its output end is connected to the rightmost conveyor roller. Two gantry frames are located in the middle of the upper surface of the conveyor frame, and a first electric cylinder is installed in the middle of the upper surface of each gantry. The moving end of the first electric cylinder extends through the upper surface of the gantry to the lower part of the gantry and connects to the pressure plate. Activating the drive motor transmits power to the connected conveyor rollers, causing them to rotate. The multiple sets of conveyor rollers, in conjunction with the conveyor belt, transport the foam. By controlling the extension of two sets of limit rods, two pressure plates are lowered, thus providing auxiliary fixation to both sides of the foam cutting area. This reduces the impact of foam displacement under pressure during cutting on the flatness of the cut surface, improving the practicality of the device.

[0008] Preferably, it also includes linear bearings and limiting rods. A set of linear bearings is provided at the front and rear of the upper end of the gantry, and a set of limiting rods is installed at the front and rear of the upper end of the pressure plate. The two sets of limiting rods extend through the two sets of linear bearings to the upper side of the gantry. The lifting and lowering process of the pressure plate is limited by the two sets of linear bearings and the limiting rods, which reduces the vibration amplitude of the pressure plate itself during the lifting and lowering process, thereby increasing the stability and practicality of the equipment.

[0009] Preferably, the adjusting device includes adjusting rollers and a geared motor. A set of adjusting rollers is horizontally installed on each of the two adjacent sides of the two sets of pressure plates. A geared motor is installed on the front end of the pressure plate, and the output end of the geared motor is connected to the adjusting roller on its respective pressure plate. When the geared motor is turned on, it transmits power to the adjusting rollers to drive them to rotate. When the pressure plate presses against the foam, the rotating adjusting roller pushes the foam in the cutting area to both sides, thereby reducing the surface tension and bulging angle of the foam in the cutting area during the pressing process, thus improving the flatness of the cut surface and improving the practicality of the device.

[0010] Preferably, the cutting device includes a rotating shaft, a blade holder, a blade, a fixed rotating shaft seat, and a second electric cylinder. A rotating shaft is installed at the middle of the upper part of the two sets of masts. The fixed end of the second electric cylinder is fitted onto the upper rotating shaft. Another rotating shaft is installed at the lower rear side of the two sets of masts. The rear part of the blade holder is fitted onto the rear rotating shaft. The blade is fixed to the middle of the blade holder by bolts. A fixed rotating shaft seat is installed at the front of the upper end of the blade holder. The moving end of the second electric cylinder is fitted onto the fixed rotating shaft seat. By controlling the extension of the second electric cylinder, the front part of the blade holder is pressed down, thereby cooperating with the blade to cut the foam. Different length blades can be replaced according to the size of the foam and installed in different positions on the blade holder, which improves the adaptability and practicality of the device.

[0011] Preferably, the device also includes a dual-output reducer, a motor, lead screws, and a lifting pallet. A set of dual-output reducers is installed at the lower part of the conveyor frame, and a motor is installed on the dual-output reducers. A set of rectangular slots is provided at the front and rear of the conveyor frame, and lead screws are vertically installed in the rectangular slots. The two output ends of the dual-output reducers are connected to the two sets of lead screws respectively. A lifting pallet is provided between the upper and lower layers of the conveyor belt. The front and rear of the lifting pallet are connected to the two sets of lead screws through a set of nuts respectively. When the motor is turned on, the power is transmitted to the two sets of lead screws through the dual-output reducers, which drives the two sets of lead screws to rotate, thereby driving the lifting pallet to move up and down. During cutting, the lifting pallet is controlled to rise, thereby providing auxiliary support for the conveyor belt, reducing the impact of conveyor belt deformation under pressure during cutting on the flatness of the cut surface, and improving the practicality of the device.

[0012] Preferably, it also includes a pressure sensor, which is installed on the moving end of the second electric cylinder; the pressure sensor monitors the pressure on the moving end of the second electric cylinder to prevent excessive pressure from damaging the surface of the conveyor belt during the cutting process, thereby improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the foam is transported and fixed by the feeding device, and the foam cutting area is assisted by the adjusting device in conjunction with the feeding device, so that the foam in the cutting area remains flat during the fixing process, thereby improving the cutting effect of the cutting device. The cutting device cuts the foam, thereby improving the practicality of the device. Attached Figure Description
