Description

Technical Field

[0001] The present invention relates to a production device for buffer pads, and more particularly to a cutting device for buffer pads. Background Art

[0002] High-temperature resistant fibers generally refer to fibers that can be safely used at temperatures above 250°C. Polytetrafluoroethylene fibers, certain aromatic polyamide fibers, polyimide fibers, etc. can be safely used between 250 and 500°C. Fibers that can be safely used above 500°C are usually inorganic fibers, such as asbestos fibers, glass fibers, metal fibers, boron nitride fibers, ceramic fibers, etc. Carbon fibers and graphite fibers can withstand high temperatures of 1500 to 3000°C. High-temperature resistant fibers have heat and corrosion resistance and are used for fire and corrosion prevention.

[0003] The buffer pads made of high-temperature resistant fibers have the characteristics of fire prevention and high-temperature resistance and can adapt to harsh usage scenarios. After the buffer pads are manufactured, a cutting machine cuts them into blocks of a predetermined size. After cutting, a blanking mechanism discharges the buffer pads. According to the prior art, the blanking method of the blanking mechanism is as follows: obtain the product, and then displace it horizontally and vertically to transfer it to a predetermined station. For example, a crossbeam processing device for a photovoltaic module disclosed in a patent document with the authorization announcement number CN 206297249 U, in which a handling device is the blanking mechanism, including a horizontal guide rail mounted on the surrounding frame and a lifting manipulator vertically installed on the horizontal guide rail. The horizontal guide rail is horizontally arranged, and the lifting manipulator is vertically arranged and fixedly connected to the horizontal guide rail at the bottom, so that the lifting manipulator can achieve horizontal displacement along the horizontal guide rail. The lifting manipulator can achieve vertical displacement, and its bottom is used to grasp the product and transport the product to the finished product station.

[0004] The blanking mechanism in the prior art includes a manipulator with longitudinal and transverse displacements, a product acquisition device, and a corresponding control system, which has a relatively complex structure, high cost, and occupies a large working space. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a blanking device for a high-temperature resistant fiber buffer pad cutting machine, which is expected to have a simple structure and small occupied space.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A blanking device on a high-temperature fiber buffer pad cutting device, including a blanking plate hinged at one end to a bracket and a lifting mechanism movably connected to the other end of the blanking plate. The lifting mechanism includes a quadrilateral frame and a motor provided on the quadrilateral frame. A first coiled steel wire and a second coiled steel wire are wound around the motor shaft. The first coiled steel wire is connected to a pair of opposite corners of the quadrilateral frame, and the second coiled steel wire is connected to the other pair of opposite corners of the quadrilateral frame. The tightening directions of the first coiled steel wire and the second coiled steel wire are opposite; the blanking plate is movably connected to the top of the lifting mechanism.

[0007] When the motor rotates forward, it drives the first coiled steel wire and the second coiled steel wire. Since the tightening directions of the first coiled steel wire and the second coiled steel wire are opposite, when the first coiled steel wire tightens, the second coiled steel wire relaxes. The tightened first coiled steel wire makes a pair of opposite corners in the left-right direction of the quadrilateral frame approach each other, while a pair of opposite corners in the up-down direction move away from each other. The pair of opposite corners moving away from each other lift the blanking plate.

[0008] When the motor rotates in the reverse direction, it drives the first coiled steel wire and the second coiled steel wire. Since the tightening directions of the first coiled steel wire and the second coiled steel wire are opposite, when the second coiled steel wire tightens, the first coiled steel wire relaxes. The tightened second coiled steel wire makes a pair of opposite corners in the up-down direction of the quadrilateral frame approach each other, while a pair of opposite corners in the left-right direction move away from each other. The pair of opposite corners approaching each other lower the blanking plate.

[0009] The conveyor line on the cutting machine transports the cut buffer pads to the blanking plate. Driven by the motor, a pair of opposite corners in the up-down direction of the quadrilateral frame approach each other, and the blanking plate rotates downward around its hinge axis with the bracket. The buffer pads on the blanking plate slide down along the blanking plate, pass by one side of the quadrilateral frame, and then fall onto the bottom plate.

[0010] Functions of the quadrilateral frame: First, it drives the blanking plate to rotate for blanking or resetting the blanking plate. Compared with a cylinder, the lifting amplitude is large, and the blanking plate can be placed very low; Second, during blanking, one side of the deformed quadrilateral frame serves as an extended part of the blanking plate, and the buffer pads sliding down from the blanking plate slide through one side of the quadrilateral frame and then fall to the working position on the bottom plate.

[0011] The lifting mechanism adopted by the present invention is composed of a quadrilateral frame, a motor, and steel wires. Compared with the manipulator in the prior art, it has a simple structure, low cost, small occupied space, and low precision requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Combined with Figures 1 to 3A blanking device on a high-temperature fiber buffer pad cutting device includes a blanking plate 10 hinged on a bracket at one end and a lifting mechanism 20 movably connected to the other end of the blanking plate, the lifting mechanism includes a quadrilateral frame 201 and a motor 202 arranged on the quadrilateral frame, a first roll of steel wire 21 and a second roll of steel wire 22 are wound on the motor shaft, the first roll of steel wire is connected to a pair of diagonals of the quadrilateral frame, the second roll of steel wire is connected to another pair of diagonals of the quadrilateral frame, and the tightening directions of the first roll of steel wire and the second roll of steel wire are opposite; the blanking plate is movably connected to the top of the lifting mechanism.

[0030] Combination Figure 1 , Figure 4 , the conveyor line 50 on the cutting machine conveys the cut cushion 60 to the blanking plate 10. Driven by the motor 202, the second coil of steel wire 22 is tightened and the first coil of steel wire 21 is released. The pair of diagonal angles of the quadrilateral frame 201 in the vertical direction are close to each other, while the pair of diagonal angles in the left and right directions are far away from each other. The blanking plate 10 rotates downward around the hinge axis 13 between it and the bracket. The cushion 60 on the blanking plate 10 slides down along the blanking plate, passes the upper left side of the quadrilateral frame 201, and then falls on the bottom plate 40.

[0031] like Figure 5 After the unloading is completed, the motor 202 rotates in the opposite direction, the first coil of steel wire 21 is tightened and the second coil of steel wire 22 is released, the left and right diagonal pairs of the quadrilateral frame 201 are close to each other, and the up and down diagonal pairs are away from each other. The unloading plate 10 rotates upward around the hinge shaft 13 with the bracket and resets.

[0032] like Figure 2 The number of the lifting mechanisms 20 is a pair, and the pair of lifting mechanisms are arranged in parallel and are both movably connected to the blanking plate 10. In actual operation, the pair of lifting mechanisms act synchronously to drive the blanking plate 10 to rotate upward or downward. The buffer pad 60 slides down through the upper left side of the pair of lifting mechanisms 201.

[0033] like Figure 1 The quadrilateral frame 201 includes an upper left plate 231, an upper right plate 232, a lower left plate 233, and a lower right plate 234. The upper left plate and the lower left plate are hinged by a first hinge shaft 235, the upper right plate and the lower right plate are hinged by a second hinge shaft 236, the upper left plate and the upper right plate are hinged by a third hinge shaft 237, and the lower left plate and the lower right plate are hinged by a fourth hinge shaft 238. The first steel wire 21 passes through the second hinge shaft, and the free end of the first steel wire is connected to the first hinge shaft. The second steel wire 22 passes through the third hinge shaft, and the free end of the second steel wire is connected to the fourth hinge shaft. The motor 202 is installed on the upper right plate 232. When unloading, the buffer block slides down along the unloading plate 10, passes through the upper left plate 231 of a pair of lifting mechanisms, and continues to slide down.

[0034] like Figure 2 ,Figure 3 At the bottom of the blanking plate 10, there is a chute 11, in which a first bearing seat 12 is fitted, and the third hinge shaft 237 is fitted with the first bearing seat. Driven by the motor 202, the quadrilateral frame 201 deforms, and the top of the quadrilateral frame acts on the blanking plate 10. When the blanking plate rotates, the first bearing seat 12 rotates relative to the third hinge shaft 237, and at the same time, the first bearing seat slides along the chute 11.

[0035] On the bottom plate 40, there is a second bearing seat, and the fourth hinge shaft 238 is fitted with the second bearing seat. The quadrilateral frame 201 is supported on the bottom plate by the second bearing seat.

[0036] As Figure 3 shown, a first sheave 241 and a second sheave 242 are installed on the motor shaft. The first steel wire coil 21 is wound around the first sheave, and the second steel wire coil 22 is wound around the second sheave. When the motor shaft rotates unidirectionally, of the two steel wire coils, one steel wire coil is tightened while the other is released.

[0037] As Figure 1 shown, on one side of the quadrilateral frame 201, there is a slider 30, which can slide along the bottom plate 40. A telescopic spring 31 is connected to the side of the slider close to the quadrilateral frame. The telescopic spring 31 is connected to a fixing member, and this fixing member is installed on the bottom plate 40. The slider 30 is located beside the lower left plate 233 of the quadrilateral frame 201. When a pair of upper and lower diagonals of the quadrilateral frame 201 approach each other, the angle between the lower left plate 233 and the bottom plate 40 becomes smaller, the lower left plate presses the slider 30, and the slider is extruded out of the angle between the lower left plate 233 and the bottom plate 40, and the telescopic spring 31 is stretched to accumulate elastic potential energy. The buffer pad 60 slides down along the blanking plate 10, then slides down along the upper left plate 231 of a pair of lifting mechanisms 20, and then slides down along the slider 30 to the bottom plate 40. At this time, the slider acts as an extension of the blanking plate 10.

[0038] As Figure 4 shown, the lower end of the buffer pad 60 sliding down along the slider 30 presses against the bottom plate 40 and leans on the slider 30. Then, when a pair of upper and lower diagonals of the quadrilateral frame 201 move away from each other, the angle between the lower left plate 233 and the bottom plate 40 becomes larger, and the slider 30 is pulled back to its original position by the telescopic spring 31. The buffer pad 60 leaning on the slider 30 leaves the slider, as Figure 5 shown, and lies flat on the bottom plate 40. Then, when a pair of upper and lower diagonals of the quadrilateral frame 201 approach each other, when the next buffer pad slides down along the blanking plate 10, the lower left plate 233 pushes the slider 30 out, as Figure 6 shown, and the slider pushes the buffer pad that has already been laid flat on the bottom plate 40 forward. The bottom end of the next buffer pad sliding down along the blanking plate 10 lands on the buffer pad that has already been laid flat, and at the same time, leans on the slider 30. After the quadrilateral frame 201 and the slider 30 are reset, the next buffer pad lies flat on the first buffer pad, but is misaligned with the first buffer pad.Figure 7 , there is no vertical alignment. When the slider 30 is pushed out again, the next cushion is pushed forward by the slider 30 and vertically aligned with the first cushion, that is, the two cushions are stacked vertically, as Figure 8 . At this time, the third cushion falls on the second cushion. After the slider 30 completes a reciprocating motion, the third cushion is again stacked vertically with the second cushion. Repeating this process, the cushions sliding down along the blanking plate 10 are successively stacked on the bottom plate 40, facilitating the workers to take them away.

[0039] As an improvement, a slide rail is provided on the bottom plate 40, and a sliding groove cooperating with the slide rail is provided on the slider 30. A roller 32 is provided on the top of the slider, and the lower left plate 233 acts on the roller 32 to drive the slider 30 to displace along the bottom plate 40.

[0040] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
