Description

Technical Field

[0001] The utility model relates to the technical field of felt conveyor belt processing and production, in particular to a composite device for producing half-hole felt conveyor belts. Background Art

[0002] Felt conveyor belt is a conveyor belt with PVC as base belt and soft felt on the surface. It has the advantages of no linting, not easy to scratch products, anti-static, etc. It is suitable for electronics, LCD display and other industries.

[0003] In the current technology, filter holes are opened on the felt conveyor belt to achieve the effect of material separation. For example, a filter hole with a diameter of 25mm is punched on the felt conveyor belt. During operation, the material larger than 25mm can be filtered out of the filter hole. The material smaller than 25mm needs to be collected again, which is a lot of work.

[0004] With the development of technology in the conveying industry, a method of punching half holes in felt conveyor belts has been proposed to collect small materials separately. For example, the diameter of the holes on the surface of the felt conveyor belt is 25mm, the thickness is 8mm, the punching depth is 5.5mm, and 2.5mm of the bottom belt is retained. In this way, when the belt is running, small materials can enter the holes and be effectively separated and collected separately.

[0005] The method for punching half holes on the felt conveyor belt is to first select the thickness of two felt products according to customer requirements (for example: one is 8mm thick and the other is 2.5mm thick), then fully punch the first product and then laminate the two products. During this operation, a laminating machine is needed to apply glue and laminate the two felts.

[0006] The width of the glue coating roller of the existing composite machine is larger than the width of the felt product. Therefore, when gluing, there will always be glue on the outside of the parts of the glue coating roller that extend beyond the flat part of the felt, and no gluing operation will be performed. This part of the glue is prone to solidification, which is not conducive to the composite operation of the felt. Based on this, a composite device for the production of semi-hole felt conveyor belts is provided. Utility Model Content

The double-roller gluing assembly 102, the guide roller assembly 103, and the composite pressure roller assembly 104 are sequentially installed on the inner side of the composite machine chassis main body 101 in the horizontal direction. The reel 105 is provided with two and is respectively rotatably installed on the composite machine chassis main body 101 through a support frame. At the front and rear ends of the box body 101, the outer sides of the two unwinding shafts 105 are respectively wound with a bottom felt 2 and an open-pore felt 3. The top of the compound machine chassis body 101 is located directly above the double-roller gluing assembly 102 and is provided with a glue adding assembly 4. The glue adding assembly 4 is used to add glue to the double-roller gluing assembly 102. The inner side of the compound machine chassis body 101 is located on the upper surface of the double-roller gluing assembly 102 and is provided with a limiting glue assembly 5. The limiting glue assembly 5 is used to limit the glue application area on the double-roller gluing assembly 102.

[0035] The glue adding component 4 includes an n-shaped bracket 401, a glue box 403, and a limit block 409;

[0036] The n-shaped bracket 401 is fixed to the top of the compound machine chassis body 101 and is located directly above the double-roller glue coating assembly 102. The glue box 403 is distributed on the top of the n-shaped bracket 401. Four limit blocks 409 are provided. The four limit blocks 409 are symmetrically fixed on both sides of the outer wall of the glue box 403 in pairs.

[0037] The glue limiting component 5 includes a glue blocking piece 501, a fixed arm 502, a bidirectional threaded rod 503, a second hand wheel 504, and a guide rod 505;

[0038] Two glue baffles 501 are provided. The two glue baffles 501 are symmetrically distributed on the inner side of the compound machine chassis body 101 and are attached to the upper surface of the double-roller glue coating assembly 102. The fixed arms 502 are symmetrically fixed to the top of the glue baffles 501 and extend above both sides of the n-shaped bracket 401.

[0039] The bidirectional threaded rod 503 and the guide rod 505 are symmetrically distributed with the center line of the glue baffle 501 as the center and both pass through the glue baffle 501 and the two fixed arms 502 on the fixed arm 502.

[0040] The second hand wheel 504 is symmetrically fixed to both ends of the bidirectional threaded rod 503. The second hand wheel 504 drives the bidirectional threaded rod 503 to move the two glue baffles 501 and the fixed arm 502 closer to or away from each other, thereby limiting the glue area on the double-roller gluing assembly 102.

[0041] The top of the fixed arm 502 is used to define the moving area of the limit block 409, so that the moving area for adding glue to the n-type bracket 401 is located between the two glue blocks 501;

[0042] The two fixed arms 502 in contact with the bidirectional threaded rod 503 are provided with internal threads matching the external threads of the bidirectional threaded rod 503;

[0043] The two fixed arms 502 in contact with the guide rod 505 are provided with through holes matching the outer wall of the guide rod 505;

[0044] The glue adding assembly 4 further includes a moving groove 402, a moving wheel 404, a glue adding valve 405, a moving seat 406, a single threaded rod 407, and a first hand wheel 408;

[0045] The moving groove 402 is formed on the top of the n-shaped bracket 401, and four moving wheels 404 are provided. The four moving wheels 404 are fixed to the bottom of the glue box 403 in a matrix arrangement and are rollingly connected to the inner side of the moving groove 402;

[0046] The glue adding valve 405 is fixed to the middle of the bottom of the glue tank 403 and is in communication with the inner cavity of the glue tank 403. The movable seat 406 is fixed to the bottom of the glue tank 403 and is distributed on one side of the glue adding valve 405. The single-threaded rod 407 completely penetrates both ends of the movable seat 406 and penetrates the end surface fixing plate of the N-shaped bracket 401. The single-threaded rod 407 is fixedly connected to the end surface of the N-shaped bracket 401 in a rotatable manner. The interior of the movable seat 406 is provided with an internal thread that matches the outer wall thread of the single-threaded rod 407.

[0047] The first hand wheel 408 is symmetrically fixed to both ends of the single threaded rod 407;

[0048] Two glue adding valves 405 are provided, and the two glue adding valves 405 are aligned with the two limit blocks 409 on one side of the glue tank 403 respectively.

[0049] In this embodiment, it should be noted that the dual-roller gluing assembly 102 includes two horizontally distributed gluing rollers, wherein the diameter of the gluing roller at the front end is larger than that of the gluing roller at the rear end, and the composite pressing roller assembly 104 includes two vertically distributed pressing rollers, and a drive assembly is provided inside the main body 1 of the composite machine chassis to respectively drive the two gluing rollers and the two pressing rollers to rotate synchronously in opposite directions. This structure is a conventional structure in the prior art, and therefore it will not be described in detail.

[0050] When the felt is composited, the lower layer of felt is distributed at the front end of the equipment, and one end of the lower layer of felt 2 passes through the bottom of the front end glue coating roller, the top of the guide roller assembly, the rear end surface of the upper pressure roller and the middle of the two pressure rollers in sequence, while the open-pore felt 3 is located at the rear end of the equipment, and one end of the open-pore felt 3 enters the middle of the two pressure rollers and is distributed on the lower surface of the lower layer of felt 2 at this position, so that the two felts are bonded to each other, and finally the composite bonded felt passes through the lower pressure roller and is transported to the next process;

[0051] In the above process, the gluing area of the double-roller gluing assembly 102 can be limited by the gluing limiting assembly 5 to match the width of the bottom felt 2. The operation steps are as follows:

[0052] By rotating the second hand wheel 504, the bidirectional threaded rod 503 is driven to rotate, and the bidirectional threaded rod 503 drives the two fixed arms 502 in contact with it to move closer to or away from each other, thereby achieving the approach and separation of the two glue blocking pieces 501. When the distance between the two glue blocking pieces 501 matches the width of the bottom felt 2, the rotation of the second hand wheel 504 can be stopped.

[0053] Then, the glue adding valve 405 can be opened to allow the glue inside the glue tank 403 to flow downward to the middle of the two glue coating rollers. At the same time, the first hand wheel 408 can be rotated to drive the one-way threaded rod 407 to rotate, and the one-way threaded rod 407 drives the moving base 406 and the glue tank 403 to move as a whole.

[0054] When the movement of the glue box 403 drives the limit block 409 to contact one fixed arm 502, the glue box 403 cannot move further. At this time, the second hand wheel 408 can be rotated in the opposite direction to move the glue box 403 in the opposite direction. When the other limit block 409 contacts the other fixed arm 502, the rotation direction of the first hand wheel 408 is reversed again. In this way, the glue is added more evenly and the glue is located between the two glue blocking pieces 501.

[0055] By cooperating with the above parts, the gluing area of the double-roller gluing assembly 102 can be matched with the width of the bottom felt 2, avoiding the situation where the glue condenses in the non-gluing area due to the gluing area being too large.

[0056] Please refer to Figures 1 to 4 The bottom of the glue baffle 501 is formed with an arc-shaped groove that matches the top outer walls of the two rollers in the double-roller gluing assembly 102, and the bottoms on both sides of the glue baffle 501 extend downward and contact the bottom felt 2, and the edges on both sides of the glue baffle 501 are in an arc structure.

[0057] In this embodiment: this structure can prevent the glue blocking piece 501 and the double-roller glue coating assembly 102 from interfering with each other;

[0058] Furthermore, the glue blocking piece 501 can also provide a certain limiting function for the movement of the bottom felt 2 to prevent the bottom felt 2 from deflecting.

[0059] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
