Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment technology, specifically a sheet material feeding and separating device. Background Technology

[0002] In automated production processes, the separation and feeding of sheet materials (such as metal sheets, plastic sheets, cardboard, silicone sheets, magnetic sheets, etc.) is a common process. In existing technologies, sheet materials are usually stored in a hopper in a stacked manner. The top sheet material is removed by means of suction cups, friction wheels or air blowing, or the sheet material is dropped one by one under the action of gravity by means of bottom tray removal.

[0003] In traditional sheet material stacking and feeding methods, when the bottom pallet is removed, the bottom sheet material often cannot be separated from the top sheet material in time due to electrostatic adsorption, oil film adhesion, or edge burrs hooking between the sheets, causing multiple sheets to fall at the same time. When the pallet is reinserted, if the clamping is not released in time, the edge of the pallet will collide with or get stuck with the sheet material, causing feeding interruption or equipment failure. Utility Model Content

[0004] The purpose of this utility model is to provide a sheet material feeding separator, which solves the problem in the traditional sheet material stacking feeding method. When the bottom pallet is removed, the bottom sheet material cannot be separated from the top sheet material in time due to electrostatic adsorption, oil film adhesion, or edge burrs hooking between the sheets material, resulting in multiple sheets falling at the same time. When the pallet is reinserted, if the clamping is not released in time, the edge of the pallet will collide with or get stuck with the sheet material, causing feeding interruption or equipment failure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sheet material feeding and separating device, including a base, a material discharge port on the upper surface of the base, four sets of support legs fixedly installed at the bottom of the base, a sheet material receiving cavity fixedly installed on the upper surface of the base, the interior of the sheet material receiving cavity is connected to the interior of the material discharge port, and a sheet material separating mechanism is provided on the upper surface of the base, with the separating end of the sheet material separating mechanism located inside the sheet material receiving cavity.

[0007] The sheet separation mechanism includes a moving part and a clamping part, and two sets of clamping parts are installed on the moving part;

[0008] The clamping part includes a mounting frame, a connecting rod is fixedly installed inside the mounting frame, and a baffle is slidably connected to the inner bottom of the mounting frame;

[0009] The baffle has a sliding groove inside, and the connecting rod is slidably connected to the sliding groove. The upper surface of the baffle is provided with a clamping plate, and the clamping plate has an arc-shaped groove inside, and the connecting rod is slidably connected to the arc-shaped groove.

[0010] Furthermore, the moving part includes a fixing plate, the upper surface of the base is fixedly mounted with the fixing plate, the upper surface of the fixing plate is fixedly mounted with a cylinder, and the upper surface of the base is symmetrically mounted with guide rails.

[0011] Furthermore, a sliding plate is fixedly installed at the output end of the cylinder, the bottom of the sliding plate is slidably connected to the upper surface of the guide rail, a mounting bracket is symmetrically installed on one outer surface of the sliding plate, and a fixed seat is symmetrically installed on the upper surface of the base, and the mounting bracket and the fixed seat are slidably connected.

[0012] Furthermore, a rectangular groove is formed on one outer surface of each of the two fixing seats, and the connecting rod is located in the rectangular groove.

[0013] Furthermore, a guide plate is fixedly installed on the inner wall of the material discharge port.

[0014] This utility model has the following beneficial effects:

[0015] (1) This utility model drives the baffle and clamping plate simultaneously through the connecting rod, and with the difference in trajectory between the straight slide and the arc slide, it realizes the precise sequential action of "first clamping the upper sheet material and then withdrawing the bottom support" and "first extending into the tray and then releasing the clamping". This mechanical linkage sequential control ensures that only the bottom sheet material falls under the action of gravity each time, while the remaining sheet material above is always stably clamped, effectively avoiding the problem of multiple sheets falling or jamming at the same time due to static electricity, oil film or edge adhesion, and significantly improving the reliability and consistency of single sheet separation.

[0016] (2) The guide plate fixedly installed on the inner wall of the material discharge port of this utility model provides a smooth and clearly guided sliding path for the bottom sheet. By reasonably designing the tilt angle and surface finish of the guide plate, the separated sheet can slide into the next process in a stable posture, preventing the sheet from flipping, deviating or hitting the inner wall of the material discharge port during the falling process.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0051] Guide plate 413: Fixedly installed on the inner wall of the discharge port 101, used to guide the falling sheet material to slide out to the next process.

[0052] Working principle: In the initial state, the stacked sheets are placed in the sheet receiving cavity 3. At this time, the baffle 409 is in the retracted state, and the clamping plate 411 is in the lifted and released state. The cylinder 402 is activated, and its output end pushes the sliding plate 404 to slide forward along the guide rail 403. The sliding plate 404 drives the mounting frame 405 to move forward. The connecting rod 408, which is fixed inside the mounting frame 405, moves forward synchronously. The connecting rod 408 passes through the sliding groove 410 of the baffle 409 and the arc groove 412 of the clamping plate 411. Therefore, when the connecting rod 408 moves forward, it will simultaneously drive the baffle 409 and the clamping plate 411. The trajectory shapes of 10 and the arc-shaped groove 412 are different, resulting in a relative motion between them. When the connecting rod 408 moves forward, it first slides within the arc-shaped groove 412, driving the two clamping plates 411 to move from both sides towards the middle, clamping and fixing all the upper sheets except the bottom sheet from both sides. At this time, the bottom sheet is not clamped and is still supported from the bottom by the baffle 409. After the clamping plates 411 are clamped in place, the connecting rod 408 continues to move forward, driving the baffle 409 to retract backward within the straight groove 410. The baffle 409 exits from under the bottom sheet, and the bottom sheet loses its bottom support and is then subjected to gravity. The material falls into the discharge port 101 and slides out along the guide plate 413 fixedly installed on the inner wall of the discharge port 101, entering the next process. At this time, the bottom sheet has finished falling, and the remaining sheet above is clamped and fixed from both sides by two clamping plates 411, keeping it suspended. The cylinder 402 retracts in the reverse direction, pulling the sliding plate 404 and the mounting bracket 405 to move backward. The connecting rod 408 moves backward synchronously. The connecting rod 408 once again drives the baffle 409 and the clamping plate 411 simultaneously. Due to the difference in trajectory between the sliding groove 410 and the arc groove 412, a reverse sequence of actions occurs again. When the connecting rod 408 moves backward, it first moves along the straight section... The drive baffle 409 moves forward within the chute 410, extending back into the bottom of the stack of sheets held in place by the two clamping plates 411. After the baffle 409 moves forward into position, the connecting rod 408 continues to move backward, sliding in the opposite direction within the arc-shaped groove 412. This drives the two clamping plates 411 to retract and release from both sides. The stack of sheets loses the clamping force from both sides and moves downward one unit. The bottom sheet falls onto the upper surface of the baffle 409, becoming the new bottom sheet, which is supported from the bottom by the baffle 409. At this point, the equipment returns to its initial state, and the entire stack of sheets falls onto the baffle 409 again, awaiting the next separation cycle.
