Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic baffle devices, specifically a pneumatic baffle device for a feed roller conveyor. Background Technology

[0002] On continuous production lines for engineered wood products (such as particleboard and fiberboard) or sheet metal, the sheets need to be transported to hot presses, cooling equipment, or stacking stations via roller conveyors.

[0003] Existing pneumatic baffles lack sufficient positioning accuracy. Rigid baffles directly obstruct the sheet material, easily causing edge collisions and deformation, and cannot adapt to the flexible buffering requirements of sheets of different thicknesses. During high-speed conveying, relying solely on mechanical obstruction is insufficient for smooth deceleration, easily causing the sheet material to bounce or slip. Furthermore, when the baffle is not in operation and retracts, it cannot fulfill its function of conveying the raw sheet material, and may even affect the normal transport of the raw sheet material.

[0004] To address the aforementioned issues, we propose a pneumatic baffle device for a feed roller conveyor. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution for a pneumatic baffle device for a feed roller conveyor, including a main frame 1, an integrated baffle 2, casters 4, a slide rail 5, and a cylinder 7; the slide rail 5 and the cylinder 7 are disposed in the body of the device; the main frame 1 is slidably connected to the slide rail 5, and its bottom surface is connected to the pushing end of the cylinder 7, so that the main frame can move up and down along the slide rail by being driven by the cylinder; the integrated baffle 2 is disposed on the side wall of the main frame 1, and the casters 4 are disposed on the top surface of the main frame 1 to reduce frictional resistance.

[0026] The integrated baffle 2 includes a baffle frame 21, an intermediate layer 22, a baffle 23, and a buffer layer 24.

[0027] The baffle frame 21 has one side wall connected to the main frame 1 and the other side wall has a slot; the intermediate layer 22 is elastically connected to the slot of the baffle frame 21 by an elastic element such as a spring, forming a primary buffer structure;

[0028] The baffle 23 is connected to the intermediate layer plate 22 by an elastic element to form a two-stage buffer structure;

[0029] The buffer layer 24 is disposed on the outer wall of the baffle 23 and is made of rubber or polyurethane material, directly contacting the board to absorb impact force. The buffer layer 24 is made of high-density rubber or silicone composite material, possessing both high elasticity and wear resistance, effectively absorbing the impact kinetic energy of the wooden board. The buffer layer 24 can also employ a layered design. The primary buffer layer of the buffer layer 24 uses a softer material (such as low-hardness silicone) to quickly disperse impact force and reduce local stress concentration. The secondary buffer layer of the buffer layer 24 uses a harder material (such as high-density rubber) to provide stable support and prevent excessive sagging of the wooden board.

[0030] The integrated adsorption plate 3 is rotatably connected to the bottom of the integrated baffle 2, and includes the hinge plate 31 and the gas flow channel 32. Multiple suction ports are opened on the top surface of the hinge plate 31, and the suction ports are arranged in an array to expand the adsorption area. The gas flow channel 32 is built into the hinge plate 31, and the gas outlet of the gas flow channel 32 is connected to the vacuum pump 6 through a corrugated pipe. When the vacuum pump 6 is started, a negative pressure is formed at the suction port, achieving downward adsorption and fixation of the plate. Figure 3As shown, when the main frame 1 rises upward, the hinge plate 31 abuts against the bottom of the roller shaft inside the device body, and the hinge plate 31 is pushed downward, allowing the structure of this application to more easily reach the designated working position through the gap between the roller shafts. When the structure of this application reaches the designated position, because the hinge plate 31 and the integrated baffle 2 are in a hinged state, the hinge plate 31 springs upward back to the initial state.

[0031] When it is necessary to recycle the adsorption integrated plate 3, first raise the adsorption integrated plate 3, then press down the hinge plate 31 to make the hinge plate 31 rotate downward, and the pushing end of the cylinder 7 drives the lowering adsorption integrated plate 3, thereby completing the recycling.

[0032] It should be noted here that the hinge plate 31 is initially in a horizontal position with the bottom surface.

[0033] like Figure 5 As shown, the gas flow channel 32 is arranged around the hinge plate 31.

[0034] When the cylinder 7 drives the main frame 1 to rise to the blocking position, the edge of the primary buffer plate first contacts the buffer layer 24, and absorbs part of the kinetic energy through compression of the elastic element.

[0035] The adsorption integrated plate 3 rises with the main frame to be close to the bottom surface of the plate, the vacuum pump 6 is started, the suction port adsorbs the bottom surface of the plate, and the negative pressure further decelerates and fixes the plate.

[0036] The precision positioning casters 4 and the slide rails 5 work together to ensure the smooth lifting of the main frame. Combined with the synergistic effect of the buffer layer and the adsorption force, millimeter-level positioning accuracy of the sheet metal is achieved.

[0037] Working principle:

[0038] Initial state: The piston rod of cylinder 7 retracts, the main frame 1 is lowered to its lowest position, and the adsorption integrated plate 3 is away from the material conveying path;

[0039] Blocking stage: When the plate is about to be in place, the piston rod of the cylinder 7 extends, the main frame 1 rises along the slide rail 5, and the integrated baffle 2 contacts the edge of the plate;

[0040] Buffer adsorption: The buffer layer 24 and the elastic element compress and absorb the impact force, while the vacuum pump 6 is started and the adsorption integrated plate 3 adsorbs the bottom surface of the plate.

[0041] Reset phase: After the plate is processed, the vacuum pump 6 is turned off, the adsorption integrated plate 3 rises first, and then the hinge plate 31 is pressed down to rotate downwards, and the pushing end of the cylinder 7 drives the descending adsorption integrated plate 3 to complete the recycling.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
