Description

Technical Field

[0001] This utility model relates to the field of carding machines, and in particular to a fixed carding plate for a carding machine. Background Technology

[0002] The carding process is a crucial step in the spinning process, and its quality directly affects the quality of the finished yarn. The main working components of a carding machine include the cylinder, doffer, movable cover plate, and fixed cover plate (fixed carding plate). Among them, the fixed carding plate is usually installed in the area of ​​the front and rear cover plates of the cylinder or at the junction of the cylinder and the licker-in roller. Its main function is to pre-card, sort, and remove impurities from the fibers, reduce the burden on the movable cover plate, and improve the overall carding effect and fiber transfer rate.

[0003] The structure of a traditional carding machine's fixed carding plate (fixed cover plate) mainly includes the fixed cover plate body and fixed cover plate strips (carding strips) with needle teeth or serrations installed on it. In existing technology, the installation and fixation between the fixed cover plate strips and the fixed cover plate body generally adopts the bolt fastening method. Specifically, each fixed cover plate strip usually needs to be tightened at both ends and the middle position using 4 to 6 Allen bolts (or similar fasteners) through the pre-set mounting holes of the fixed cover plate strip or the fixed cover plate body;

[0004] When it is necessary to replace, clean, or maintain the fixing cover strips, operators must disassemble and install a large number of bolts one by one. Especially for the entire carding machine, it is often necessary to replace multiple fixing carding plates, and the total number of bolts to be disassembled can reach dozens or even hundreds. This process is extremely tedious and time-consuming, usually requiring downtime of 1-2 hours or even longer. This seriously affects the production efficiency of the carding machine, increases unplanned downtime, reduces equipment utilization, and further increases the labor intensity of operators.

[0006] To achieve the above objectives, this utility model provides a carding machine fixed combing plate, including a fixed cover plate and a fixed cover plate strip disposed thereon, with fixed blocks detachably installed at both ends of the fixed cover plate;

[0007] The fixed cover strip consists of a comb strip and a U-shaped frame fixed thereon. The U-shaped frame overlaps the fixed cover strip to form a movable compartment between the two.

[0008] The top of the fixed cover plate has multiple through holes, through which the limiting member slides through the holes;

[0009] The top wall of the U-shaped frame is symmetrically fixed with L-shaped reinforcing ribs, and a gap is formed between the two reinforcing ribs. The upper end of the limiting member extends into the movable compartment through the gap.

[0010] The adjusting rod is horizontally rotatably installed inside the fixed cover plate, and multiple adjusting blocks are threaded at equal intervals on the surface of the adjusting rod.

[0011] The side wall of the adjusting block is provided with a movable groove, and the slider is fixed at an inclination inside the groove.

[0012] The lower end of the limiting member is fixedly connected to a connecting block, and the connecting block is slidably sleeved on the slider through a sliding groove.

[0013] Rotating the adjusting rod drives the adjusting block to move horizontally, and through the cooperation of the slider and the inclined surface of the connecting block, it drives all the limiting parts to rise and fall synchronously.

[0014] Preferably, the top of the limiting member is provided with a tapered end that passes through the gap between the two L-shaped reinforcing ribs.

[0015] Preferably, a limiting groove is provided at the bottom inner side of the L-shaped reinforcing rib, and its outline matches the conical surface of the conical end.

[0016] Preferably, the surface of the adjusting rod is provided with external threads in segments, and adjacent adjusting blocks respectively engage with different thread segments.

[0017] Preferably, a guide block is fixed to the top of the adjusting block, and a guide groove that cooperates with the guide block is provided on the top wall of the fixed cover plate.

[0018] Preferably, the inclination angle of the groove of the connecting block is consistent with the inclination angle of the slider.

[0019] Preferably, the adjusting rod is rotatably mounted inside the fixed cover plate via multiple support seats. The bottom of the support seats is fixed to the bottom wall of the fixed cover plate. A bearing is provided between the inside of the support seat and the surface of the adjusting rod. The inner ring of the bearing is fixedly connected to the surface of the adjusting rod, and the outer ring of the bearing is fixedly connected to the inside of the support seat.

[0020] Preferably, one end of the adjusting rod is fixed with a hexagonal head bolt, and the corresponding fixing block has a hexagonal through groove adapted to the hexagonal head bolt.

[0021] The beneficial effects of this utility model are as follows: By using a carding machine fixed carding plate of this utility model, through the setting of components such as adjusting rod, limiting parts and adjusting blocks, during the assembly and disassembly of the carding machine fixed carding plate, the rotation of the adjusting rod can realize the synchronous lifting and lowering of all limiting parts, so as to fix and disassemble the fixed cover plate and the fixed cover plate strip, which can improve the assembly and disassembly efficiency between the fixed cover plate and the fixed cover plate strip, realize fast and efficient overall assembly and disassembly, significantly shorten downtime, and reduce the labor intensity of operators;

[0022] By incorporating components such as the adjusting rod, hexagonal head bolts, and fixing blocks, the adjusting rod can be mechanically locked after the fixing blocks are fully installed, thus preventing the adjusting rod from shifting and further improving the stability of the installation between the fixing cover plate and the fixing cover plate strip.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] The first aspect of this utility model proposes a carding machine with a fixed carding plate, such as... Figure 1-7 As shown, it includes a fixed cover plate 1 and a fixed cover plate strip 2 disposed thereon, and fixed blocks 3 can be detachably installed at both ends of the fixed cover plate 1; it should be added that the fixed blocks 3 can be detachably installed at the ends of the fixed cover plate 1 by means of bolts on both sides.

[0036] The fixed cover strip 2 consists of a combing strip and a U-shaped frame fixed thereon. The U-shaped frame overlaps the fixed cover strip 1, so that a movable compartment is formed between the two.

[0037] The top of the fixed cover plate 1 has multiple through holes, through which the limiting piece 5 slides through;

[0038] The top wall of the U-shaped frame is symmetrically fixed with L-shaped reinforcing ribs 4, and a gap is formed between the two reinforcing ribs. The upper end of the limiting piece 5 passes through the gap and extends into the movable chamber. When installing the fixed cover strip 2, the limiting piece 5 is first moved up to the position, and then the movable chamber is formed between the bottom U-shaped frame of the fixed cover strip 2 and the fixed cover plate 1, which facilitates the sliding installation of the fixed cover strip 2 by pushing it from the fixed cover plate 1.

[0039] An adjusting rod 6 is horizontally rotated and installed inside the fixed cover plate 1. Multiple adjusting blocks 7 are connected to the surface of the adjusting rod 6 by equidistant threads.

[0040] The side wall of the adjusting block 7 is provided with a movable groove 701, and the sliding block 7011 is fixed in an inclined position in the groove. It should be added that, according to the number of fixed cover strips 2 installed on the fixed cover plate 1, a corresponding number of movable grooves 701 can be opened on the side wall of the adjusting block 7. When one fixed cover strip 2 is installed, one movable groove 701 can be opened on one side of the adjusting block 7. When two fixed cover strips 2 are symmetrically installed on the fixed cover plate 1, movable grooves 701 can be opened on both sides of the adjusting block 7 respectively.

[0041] The lower end of the limiting member 5 is fixedly connected to the connecting block 501, and the connecting block 501 is slidably sleeved on the slider 7011 through the sliding groove 5011.

[0042] Rotating the adjusting rod 6 drives the adjusting block 7 to move horizontally. Through the cooperation of the slider 7011 and the inclined surface of the connecting block 501, all the limiting parts 5 are moved up and down synchronously.

[0043] After the installation of the fixed cover strip 2 is completed, the adjustment rod 6 is rotated to move the multiple threaded horizontal adjustment blocks 7 on the surface of the adjustment rod 6. At this time, the slider 7011, which is fixed at an inclination in the movable groove 701 on one side of the adjustment block 7, moves horizontally through the adjustment block 7, causing the connecting block 501 on the surface of the slider 7011 to move the limiting member 5 downward. At this time, the top of the limiting member 5 moves closer to the bottom of the inner side of the two symmetrical L-shaped reinforcing ribs 4. When the limiting member 5 moves to the bottom, the top of the limiting member 5 presses the bottom of the inner side of the L-shaped reinforcing rib 4, thereby realizing that the limiting member 5 presses synchronously on the bottom wall of the L-shaped reinforcing rib 4. This avoids the traditional structure of using 4-6 internal hex bolts to fix each combing plate, which affects the replacement time of the whole machine and reduces production efficiency.

[0044] In this embodiment: the top of the limiting member 5 is provided with a tapered end, which passes through the gap between the two L-shaped reinforcing ribs 4.

[0045] In this embodiment, a limiting groove 401 is formed at the bottom inner side of the L-shaped reinforcing rib 4, the outline of which matches the conical surface of the conical end. With the conical end of the limiting member 5 at the top, and under the action of the limiting groove 401 matching the conical surface of the conical end, when the limiting member 5 moves down into place, the conical end of the limiting member 5 presses against the bottom inner side of the L-shaped reinforcing rib 4, allowing the conical end to embed into the limiting groove 401, so that the conical surface of the conical end fits tightly against the inner wall of the limiting groove 401, further improving the stability of the fixed cover strip 2 installation.

[0046] In this embodiment, the surface of the adjusting rod 6 is segmented with external threads, and adjacent adjusting blocks 7 engage with different thread segments respectively. It should be noted that when the adjusting rod 6 is rotated, the adjusting rod 6 can simultaneously drive multiple adjusting blocks 7 on its surface to engage synchronously, so that all limiting parts 5 can rise and fall synchronously, improving the disassembly and assembly efficiency between the fixed cover plate 1 and the fixed cover plate strip 2, realizing fast and efficient overall disassembly and assembly, significantly shortening downtime, and reducing the labor intensity of operators.

[0047] In this embodiment: a guide block is fixed to the top of the adjusting block 7, and a guide groove that cooperates with the guide block is opened on the top wall of the fixed cover plate 1. When the adjusting rod 6 rotates and drives the adjusting block 7 to move horizontally, the guide block at the top of the adjusting block 7 slides on the top wall of the fixed cover plate 1, which further improves the stability of the movement of the adjusting block 7.

[0048] In this embodiment, the tilt angle of the groove 5011 of the connecting block 501 is the same as the tilt angle of the slider 7011. This allows the adjusting block 7 to move vertically by driving the corresponding connecting block 501 through the slider 7011 on the side wall, thereby realizing the lifting and lowering of the limiting member 5.

[0049] In this embodiment: the adjusting rod 6 is rotatably mounted inside the fixed cover plate 1 via multiple support seats 8. The bottom of the support seats 8 is fixed to the bottom wall of the fixed cover plate 1. A bearing is provided between the inside of the support seat 8 and the surface of the adjusting rod 6. The inner ring of the bearing is fixedly connected to the surface of the adjusting rod 6, and the outer ring of the bearing is fixedly connected to the inside of the support seat 8. It should be noted that the support seats 8 further improve the stability of the rotation of the adjusting rod 6.

[0050] In this embodiment: one end of the adjusting rod 6 is fixed with a hexagonal head bolt 601, and the corresponding fixing block 3 has a hexagonal through groove that matches the hexagonal head bolt 601.

[0051] To prevent the adjusting rod 6 from shifting under high-speed vibration during the use of the carding machine's fixed combing plate, and to avoid the possibility of the needle teeth on the fixed cover strip 2 damaging the cylinder, a hexagonal head bolt 601 fixed at the end of the adjusting rod 6 and a corresponding fixed block 3 with a hexagonal through groove are provided for the fit. This allows the adjusting rod 6 to be mechanically locked after the fixed block 3 is installed, thereby preventing the adjusting rod 6 from shifting and further improving the stability of the installation between the fixed cover plate 1 and the fixed cover strip 2.
