Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to an adaptive counterweight device for a loom. Background Technology

[0002] Currently, the winding operation of looms usually adopts a pair of rollers for friction winding. The surface linear speed of the rollers is relatively easy to control and keep constant, which can correspond well with the constant speed of the machine.

[0003] However, this method has a persistent drawback: when the fabric roll is very small, the friction between the roll and the roller is minimal, leading to slippage because the roll is very light. This results in a loose core, making the roll too small to roll properly, and the resulting wrinkles and creases become permanent and difficult to remove, thus limiting its applicability. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing an adaptive counterweight device for a loom with high applicability and stability.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An adaptive counterweight device for a weaving machine includes a frame, on which roller one and roller two are axially fixed. An upper section for rolling fabric is formed between roller one and roller two. The device is characterized by further including a connecting plate, a pressure roller, and a counterweight roller. The connecting plate is triangular, with connecting parts one, two, and three at its triangular bends. The pressure roller is axially fixed to connecting part one, the counterweight roller is connected to connecting part two, and connecting part three is movably connected to the side of the frame. Initially, the pressure roller is located directly below the counterweight roller. Under the weight of the counterweight roller, the pressure roller presses tightly against the outside of the fabric roll in the working section. As the diameter of the fabric roll increases, the fabric roll pushes the pressure roller upwards. With the oscillation of the connecting plate, the height of the pressure roller is between the height of the counterweight roller and the height of connecting part three.

[0007] In the adaptive counterweight device of this loom, the pressure roller always tends to press against the working section under the action of gravity. Therefore, uneven placement in the working section can be stably compressed by the pressure roller.

[0008] As the outer diameter of the fabric roll continuously increases at the working section, the pressure roller moves upward and swings accordingly. At the same time, under the action of the counterweight roller, the pressure roller can always stably press against the fabric roll.

[0009] As the pressure roller moves upward, the counterweight roller moves away from the working area. In other words, the larger the diameter of the fabric roll, the smaller the pressure applied by the pressure roller to the roll; that is, the larger the fabric roll, the less friction between the roll and rollers one and two. This ensures the fabric roll is stably wound.

[0010] In the aforementioned adaptive counterweight device for the loom, the connecting plate is an isosceles triangle, with connecting part one and connecting part two located at the two base angles of the isosceles triangle, and connecting part three located at the vertex angle of the isosceles triangle.

[0011] In the aforementioned adaptive counterweight device for a loom, the counterweight roller is a solid metal roller.

[0012] Solid metal rollers allow counterweight rollers to have a relatively large weight.

[0013] In the aforementioned adaptive counterweight device for the loom, the pressure roller is cylindrical.

[0014] In the aforementioned adaptive counterweight device for the loom, the frame has a vertically arranged guide rail, one end of the pressure roller is axially fixed to the connecting part, and the other end of the pressure roller is embedded in the guide rail.

[0015] Because the pressure roller is connected to the guide rail, it can move straight up and down when pushed by the fabric roll.

[0016] In the aforementioned adaptive counterweight device for the loom, the guide rail is located directly above the space between roller one and roller two.

[0017] This structure allows the pressure roller to press stably directly above the fabric roll.

[0018] In the aforementioned adaptive counterweight device for the loom, a horizontally arranged support plate is fixedly connected to the side of the frame, and the aforementioned connecting part is movably connected to the support plate.

[0019] The support plate provides support for the connecting part three, ensuring that the connecting part three will not move up and down during the swinging process.

[0020] In the aforementioned adaptive counterweight device for a loom, the support plate has a horizontal and elongated limiting groove, and the connecting part has connecting pins fixedly connected to its three sides, with the connecting pins embedded in the limiting groove.

[0021] The connection between the connecting pin and the limiting groove enables the connecting plate to swing stably, while the connecting part three always moves in a horizontal position during the swing.

[0022] Compared with existing technologies, the smaller the fabric roll in the adaptive counterweight device of this loom, the greater the friction between the fabric roll and rollers one and two; the larger the fabric roll, the smaller the friction between the fabric roll and rollers one and two. This ensures that there is sufficient friction between the fabric roll and the rollers when the fabric roll has a small diameter, and the friction between the fabric roll and the rollers is appropriately reduced when the fabric roll has a large diameter, effectively improving the rolling stability of the fabric roll.

[0023] Meanwhile, the counterweight roller and the pressure roller are both connected to the connecting plate, and the entire device has a relatively compact structure and high practical value. Attached Figure Description

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1 and Figure 2 As shown, the adaptive counterweight device of this loom includes a frame 1, on which roller 2 and roller 3 are axially fixed. An operating section for rolling fabric is formed at the upper part between roller 2 and roller 3.

[0031] It also includes a connecting plate 4, a pressure roller 5, and a counterweight roller 6. The connecting plate 4 is triangular, and the triangular bends of the connecting plate 4 are respectively connecting part 1 4a, connecting part 2 4b, and connecting part 3 4c. The pressure roller 5 is axially fixed at connecting part 1 4a, the counterweight roller 6 is connected at connecting part 2 4b, and connecting part 3 4c is movably connected to the side of the frame 1. In the initial state, the pressure roller 5 is located directly below the counterweight roller 6. Under the gravity of the counterweight roller 6, the pressure roller 5 can press tightly against the outside of the fabric roll at the working part. When the diameter of the fabric roll increases, the fabric roll can push the pressure roller 5 upward. After the entire connecting plate 4 swings, the height position of the pressure roller 5 is between the height position of the counterweight roller 6 and the height position of connecting part 3 4c.

[0032] The connecting plate 4 is an isosceles triangle, with the first connecting part 4a and the second connecting part 4b located at the two base angles of the isosceles triangle, and the third connecting part 4c located at the vertex angle of the isosceles triangle.

[0033] The counterweight roller 6 is a solid metal roller.

[0034] The pressure roller 5 is cylindrical.

[0035] The frame 1 has a vertically arranged guide rail 7. One end of the pressing roller 5 is axially fixed to the connecting part 4a, and the other end of the pressing roller 5 is embedded in the guide rail 7.

[0036] The guide rail 7 is located directly above the space between roller 1 2 and roller 2 3.

[0037] A horizontally arranged support plate 8 is fixedly connected to the side of the frame 1, and the aforementioned connecting part 3 4c is movably connected to the support plate 8.

[0038] The support plate 8 has a horizontal and elongated limiting groove 8a, and the connecting part 4c is fixedly connected to the side with a connecting pin 9, which is embedded in the limiting groove 8a.

[0039] In the adaptive counterweight device of this loom, the pressure roller always tends to press against the working section under the action of gravity. Therefore, uneven placement in the working section can be stably compressed by the pressure roller.

[0040] As the outer diameter of the fabric roll continuously increases at the working section, the pressure roller moves upward and swings accordingly. At the same time, under the action of the counterweight roller, the pressure roller can always stably press against the fabric roll.

[0041] As the pressure roller moves upward, the counterweight roller moves away from the working area. In other words, the larger the diameter of the fabric roll, the smaller the pressure applied by the pressure roller to the roll; that is, the larger the fabric roll, the less friction between the roll and rollers one and two. This ensures the fabric roll is stably wound.

[0042] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
