Description

Technical Field

[0001] This utility model relates to the field of sheet fabric technology, and in particular to a feeding device for dry granule fabric. Background Technology

[0002] To improve the decorative effect of decorative panels, existing technologies involve applying dry granules of different colors or sizes to the surface of the panels. These granules melt under the high temperature during panel forming, and the cooled granules form decorative particles or lines protruding from the panel surface.

[0003] When applying dry pellets, the existing technology uses a frame mold, which is placed in the feeding area. Then, the hopper is moved to the feeding area, and the dry pellets in the hopper are fed into the frame of the mold in one go.

[0004] When dry granules are fed into the fabric application area from the hopper through the discharge port in one go, it is easy for excessive amounts of dry granules to accumulate in some areas, exceeding the preset fabric application space. This results in a significant difference between the fabric application effect and the design effect. Utility Model Content

[0045] A feeding device for dry granular fabric includes a hopper 1, a base 2, multiple baffle drive units 5 and multiple baffles 6;

[0046] The hopper 1 is provided with a feed inlet and a discharge outlet 10; the hopper 1 is inserted into the base 2, the feed inlet is located on the top surface of the hopper 1 and faces upward, and the discharge outlet 10 is located at the bottom of the hopper 1 and is exposed on the bottom surface of the base 2.

[0047] Multiple baffles 6 are arranged along the length of the discharge port 10 on one side of the discharge port 10, and multiple baffle driving units 5 are arranged adjacently and mounted on one side of the discharge port 10; one end of each baffle 6 is used to block and close the discharge port 10, and the other end of each baffle 6 is connected to the output end of the corresponding baffle driving unit 5; the baffle driving unit 5 drives the baffle 6 to move closer to or further away from the discharge port 10.

[0048] Figure 1 This is a schematic diagram of one embodiment of a feeding device for dry granular fabric according to the present invention. Figure 2 This is a schematic diagram of the cross-sectional structure of the feeding device of this utility model.

[0049] The present invention provides a feeding device for dry granular fabric, which is movably mounted above the fabric working surface of the sheet production process.

[0050] like Figure 1-4 As shown, after the dry granules to be distributed are put into the hopper 1, when the feeding device for dry granule distribution of this utility model moves above the area to be distributed, the baffle 6 located directly above the point to be distributed moves away from the discharge port 10 under the drive of the corresponding baffle driving unit 5, opening the corresponding part of the discharge port 10, so that the dry granules in the hopper 1 are distributed at the corresponding point through the corresponding part of the discharge port 10, thereby completing the fixed-point distribution of dry granules. Furthermore, the amount of dry granules distributed can be limited by controlling the movement stroke of the baffle 6 and the opening time of the corresponding part of the discharge port 10.

[0051] Furthermore, it also includes an adjustment plate drive unit 3 and an adjustment plate 4;

[0052] The regulating plate drive unit 3 and the baffle drive unit 5 are respectively mounted on both sides of the discharge port 10;

[0053] The adjusting plate 4 is disposed above the baffle 6, and the top surfaces of the plurality of baffles 6 respectively abut against the bottom surface of the adjusting plate 4; one end of the adjusting plate 4 extends into the discharge port 10, and a discharge gap 101 is formed between the end face of one end of the adjusting plate 4 and the inner wall surface of the opposite discharge port 10; the other end of the adjusting plate 4 is connected to the adjusting plate driving unit 3, and the adjusting plate driving unit 3 drives the adjusting plate 4 to move to adjust the spacing of the discharge gap 101.

[0054] like Figure 2 and Figure 4 As shown, the spacing of the discharge gap 101 can be adjusted by the cooperation of the adjusting plate 4 and the adjusting plate driving unit 3, thereby adjusting the discharge width of the dry granules output from the discharge port 10, and thus controlling the actual amount of material distributed at the material distribution point and the corresponding dry granule distribution width, so as to further improve the positioning and material distribution accuracy of the feeding device.

[0055] Furthermore, it also includes a sealing plate 9;

[0056] The sealing plate 9 is made of elastic material, and the sealing plate 9 is installed on the bottom surface of the base 2 and located on the other side of the discharge port 10;

[0057] When one end of the baffle 6 closes the discharge port 10, one end of the baffle 6 abuts against the sealing plate 9.

[0058] like Figure 2 and Figure 4As shown, by having one end of the sealing plate 9 abut against the sealing plate 9 of the elastic material, the tightness of the baffle 6 in sealing the discharge port 10 can be improved, thus preventing the leakage of dry granular material.

[0059] Furthermore, a plurality of magnetic blocks 21 are embedded in the bottom surface of the base 2;

[0060] The adjusting plate 4 is a magnetic conductor, and the bottom surface of the magnetic suction block 21 is attracted to the top surface of the adjusting plate 4.

[0061] like Figure 5 and Figure 6 As shown, multiple magnetic blocks 21 provide upward suction to the adjusting plate 4, which can reduce the pressure of the adjusting plate 4 on the baffle 6, prevent the baffle 6 from sinking during operation, and thus ensure the operational stability of the positioning and fabric distribution device 3.

[0062] Furthermore, the baffle drive unit 5 includes a plurality of pneumatic solenoid valves 51 and a plurality of piston rods 52;

[0063] The pneumatic solenoid valves 51 and the piston rods 52 are in one-to-one correspondence, and the piston rods 52 extend horizontally along the length direction perpendicular to the discharge port 10;

[0064] The pneumatic solenoid valve 51 controls the extension and retraction of the corresponding piston rod 52; the other end of the baffle 6 is connected to the output end of the piston rod 52.

[0065] like Figure 2-6 As shown, the baffle drive unit 5 can be a pneumatic solenoid valve. The baffle drive unit 5 with a pneumatic solenoid valve includes multiple pneumatic solenoid valves 51 and multiple piston rods 52. The corresponding piston rod 52 can be extended or retracted by any pneumatic solenoid valve 51, thereby moving the corresponding baffle 6, opening the corresponding part of the discharge port 10 for positioning and material distribution, or closing the corresponding part of the discharge port 10 after the material distribution is completed.

[0066] The piston rod 52 extends horizontally along the length direction perpendicular to the discharge port 10, which can prevent the moving baffle 6 from tilting and not perpendicular to the discharge port 10, and help improve the tightness of the baffle 6 in covering and sealing the discharge port 10.

[0067] Furthermore, it also includes multiple guide rods 7;

[0068] The other end of the baffle 6 is provided with a connecting part 61, which extends upward in a direction perpendicular to the baffle 6; the connecting part 61 is provided with a guide hole 610, which penetrates the connecting part 61 in a horizontal direction;

[0069] The connecting part 61 is connected to the output end of the piston rod 52;

[0070] One end of the guide rod 7 is inserted into the side of the base 2 opposite to the baffle drive unit 5, and the other end of the guide rod 7 extends horizontally and passes through the guide hole 610.

[0071] like Figure 3 and Figure 7 As shown, the guide rod 7 guides the connecting part 61, which improves the smoothness of the movement of the baffle 6.

[0072] Preferably, two adjacent piston rods 52 are arranged in a staggered manner.

[0073] like Figure 2-6 As shown, since the width of the baffle 6 in the horizontal direction is limited, if multiple piston rods 52 are arranged on the same horizontal plane, interference may easily occur between two adjacent piston rods 52 due to insufficient installation space. Setting the two adjacent piston rods 52 vertically offset can avoid interference and improve the installation convenience of the baffle 6 and piston rods 52.

[0074] Furthermore, the guide rod 7 is provided with a limiting ring 71;

[0075] The outer circumference of the limiting ring 71 protrudes outward from the middle of the guide rod 7;

[0076] One end of the limiting ring 71 is used to abut against the connecting part 61.

[0077] like Figure 2-4 As shown, by limiting the distance between the connecting part 61 and the base 2 by the limiting ring 71, the stroke of the baffle 6 can be limited to adapt to the fabric requirements of different application amounts.

[0078] Furthermore, it also includes cover plate 8;

[0079] The cover plate 8 is located near the side of the base 2 and is installed above the baffle driving unit 5. The cover plate 8 covers the top surface of the baffle driving unit 5 and the top surfaces of the plurality of baffles 6.

[0080] like Figure 1 and Figure 2 As shown, when feeding material into hopper 1, the cover plate 8 can prevent dry granules from falling into the gap between baffle drive unit 5 and baffle 6, thus avoiding affecting the stroke of baffle 6 and consequently affecting the blocking and sealing effect on discharge port 10.

[0081] Furthermore, the cover plate 8 is divided into two parts and is fitted with hinges 81;

[0082] The portion of the cover plate 8 that covers the baffle drive unit 5 and the baffle 6 can be folded upwards via the hinge 81.

[0083] like Figure 1 and Figure 2 As shown, when maintenance of the baffle drive unit 5 or the baffle 6 is required, the portion of the cover plate 8 that covers the baffle drive unit 5 and the baffle 6 can be folded upwards, thereby improving the convenience of maintenance operations.

[0084] In summary, such as Figure 1-7 The embodiment of the present invention shown includes a feeding device for dry granule fabric, comprising multiple baffles 6 that can be moved by multiple baffle drive units 5. During the movement, any baffle 6 can open the corresponding part of the discharge port 10 to achieve fixed-point feeding of dry granule fabric. The amount of dry granule fabric applied can be limited by controlling the movement stroke of the baffle 6 and the opening and closing time of the corresponding part of the discharge port 10, thereby reducing the difference between the fabric application effect and the design effect.

[0085] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
