Description

Technical Field

[0001] The utility model belongs to the technical field of looms, and particularly relates to a loom edge trimming mechanism. Background Art

[0002] When weaving geotextiles or base fabrics for some other purposes, plastic flat filaments are often used as warp and weft yarns in a loom. Among them, the plastic flat filaments of some materials have high hardness and poor flexibility, resulting in frayed edges in the weft direction of the cloth woven by the loom, which affects the appearance of the product. Moreover, the normal operation of the loom is generally to weave the cloth while winding the woven cloth. It is very difficult to deal with the burrs on the weft edge of the wound cloth.

[0003] Therefore, how to trim the frayed edges after the loom weaves the cloth and before the cloth is wound is an urgent problem to be solved in this field. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a loom edge trimming mechanism for solving the technical problem that the existing loom cannot process the weft frayed edges of the woven fabric after weaving and before winding.

[0005] The technical solution of the utility model for solving the above technical problems is as follows: A loom edge trimming mechanism is provided on a loom, and includes:

[0006] A mounting block, which is arranged on the side of the shuttle box of the loom;

[0007] A shearing assembly, which is arranged on the bottom surface of the mounting block, and the cutting edge of the shearing assembly is aligned with the weft edge of the woven fabric;

[0008] A driving link assembly, one end of which is connected to the shearing assembly, and the other end of which is connected to the middle frame of the loom.

[0009] The utility model utilizes the original middle frame of the loom as a power source. During the operation of the loom, the middle frame will regularly move up and down reciprocally, which can drive the driving link assembly to work. The driving link assembly drives the shearing assembly to shear the frayed edges of the weft of the woven fabric to achieve the purpose of shaping.

[0010] Further: The shearing assembly includes a moving block and a static block;

[0011] The static block is arranged below the weft edge of the woven fabric and is arranged on a fixed seat on the bottom surface of the mounting block;

[0012] The moving block is arranged in a limiting hole opened on the mounting block. The opposite edges of the moving block and the static block are cutting edges, and the moving block is connected to one end of the driving link assembly.

[0013] Further: The shearing component is a pair of scissors, the cutting edge of the scissors faces the weft edge of the fabric, the stationary handle of the scissors is fixedly connected to the mounting block, and the moving handle of the scissors is connected to one end of the driving link assembly.

[0014] Beneficial effects of the above two steps: Different types of structures of the shearing component.

[0015] Further: The driving link assembly includes:

[0016] A fixing frame, which is installed on the side of the shuttle receiving box of the loom and above the mounting block;

[0017] A driving link, one end of the driving link is hinged to the middle frame, and the other end of the driving link is hinged to the fixing frame;

[0018] A shearing link, one end of the shearing link is hinged to the rod body of the driving link, and the other end of the shearing link is hinged to the shearing component.

[0019] Beneficial effects of this step: The reciprocating up and down movement of the shearing link is realized by the swinging of the driving link, so as to realize the shearing function of driving the shearing component.

[0020] Further: A stabilizing block is provided on the rod body of the driving link, and the stabilizing block is pivotally connected to the fixing frame;

[0021] The shearing link is pivotally connected to the stabilizing block.

[0022] Beneficial effects of this step: The stabilizing block is to improve the running stability of the driving link assembly.

[0023] Further: The two ends of the shearing link are provided with spherical plain bearings.

[0024] Beneficial effects of this step: The spherical plain bearings can maintain the movement precision and have a certain freedom margin at the same time.

[0025] Further: The middle part of the mounting block is connected to the shuttle receiving box by bolts, and the tail of the mounting block is pivotally connected to the shuttle receiving box.

[0026] Beneficial effects of this step: When the cutting edge of the shearing component becomes blunt and the shearing component needs to be disassembled for replacement or regrinding, this mounting block is easier to disassemble; specifically, only one bolt needs to be removed, and the mounting block can be turned upwards to facilitate the disassembly of the shearing component.

[0027] Further: A guiding block is also provided at the front end of the bottom surface of the mounting block. A guiding groove is formed on the side surface of the guiding block. The guiding groove engages with the weft edge of the woven fabric, and the outlet of the guiding groove is aligned with the shearing assembly.

[0028] Beneficial effects of this step: The guiding groove of the guiding block can guide the weft edge to accurately enter the cutting edge of the shearing assembly.

[0029] The beneficial effects of the present utility model are:

[0030] The structure of this application is simple and does not require an additional power source. It can synchronously trim the frayed edges of the weft direction of the woven fabric before winding only under the drive of the middle frame, and has no impact on the normal operation of the loom itself.

[0045] Embodiment

[0046] As Figure 1 and Figure 2 shown, a loom edge - cutting mechanism provided by the present utility model is arranged on a loom and includes:

[0047] A mounting block 1, and the mounting block 1 is arranged on the side of the shuttle - receiving box 2 of the loom;

[0048] A cutting assembly 3, and the cutting assembly 3 is arranged on the bottom surface of the mounting block 1, and the cutting edge of the cutting assembly 3 is aligned with the weft - wise edge of the fabric 6;

[0049] A driving link assembly 4, one end of the driving link assembly 4 is connected to the cutting assembly 3, and the other end of the driving link assembly 4 is connected to the middle frame 5 of the loom.

[0050] In the present utility model, the middle frame 5 and the shuttle - receiving box 2 are both original components of the loom. There is enough space between the shuttle - receiving box 2 and the weft - wise edge of the fabric 6 to install the structure of this application. Using the original middle frame 5 of the loom as the power source, the middle frame 5 will regularly move up and down reciprocally during the operation of the loom, which can drive the driving link assembly 4 to work. The driving link assembly 4 drives the cutting assembly 3 to cut the frayed edge of the weft - wise edge of the fabric 6, so as to achieve the purpose of shaping without affecting the normal production and normal winding of the fabric 6.

[0051] As Figure 3 shown, the first embodiment of the cutting assembly 3 includes a moving block 31 and a static block 32;

[0052] The static block 32 is arranged below the weft - wise edge of the fabric 6, and the static block 32 is arranged on the fixed seat 11 on the bottom surface of the mounting block 1;

[0053] The moving block 31 is arranged in the limiting hole 12 opened on the mounting block 1. The edge of the moving block 31 opposite to the static block 32 is a cutting edge, and the moving block 31 is connected to one end of the driving link assembly 4.

[0054] As Figure 1 shown, the second embodiment of the cutting assembly 3 is a pair of scissors. The cutting opening of the scissors faces the weft - wise edge of the fabric 6. The static handle of the scissors is fixedly connected to the mounting block 1, and the moving handle of the scissors is connected to one end of the driving link assembly 4.

[0055] As described above, the shearing component 3 has various implementation structures, including shearing, punching, etc. Specifically, when the shearing component 3 is as described in Embodiment 1, the moving block 31 can move up and down in the matching limiting hole 12, or can be connected to the side surface of the mounting block 1 through a linear slide rail or the like. The moving block 31 can be hinged or pivoted to one end of the driving link assembly 4; when the shearing component 3 is as described in Embodiment 2, the two handles of the scissors can also be directly driven by the driving link assembly 4 to perform opening and closing actions simultaneously, but this will increase the complexity of the structure.

[0056] As Figure 1 and Figure 2 shown, the driving link assembly 4 includes:

[0057] A fixed frame 41, the fixed frame 41 is installed on the side surface of the shuttle receiving box 2 of the loom and above the mounting block 1;

[0058] A driving link 42, one end of the driving link 42 is hinged to the middle frame 5, and the other end of the driving link 42 is hinged to the fixed frame 41;

[0059] A shearing link 43, one end of the shearing link 43 is hinged to the rod body of the driving link 42, and the other end of the shearing link 43 is hinged to the shearing component 3.

[0060] By swinging the driving link 42, the up-and-down reciprocating movement of the shearing link 43 is realized, so as to realize the shearing function of driving the shearing component 3.

[0061] On the basis of the above technical solution, a stabilizing block 44 is provided on the rod body of the driving link 42, and the stabilizing block 44 is pivotally connected to the fixed frame 41;

[0062] The shearing link 43 is pivotally connected to the stabilizing block 44.

[0063] The degree of freedom of pivotal connection is smaller than that of hinge connection, and it can only rotate around the central axis. Therefore, the stabilizing block 44 is to improve the running stability of the driving link assembly 4.

[0064] On the basis of the above technical solution, spherical plain bearings 45 are provided at both ends of the shearing link 43.

[0065] Threads are provided at both ends of the shearing link 43, and the threads are connected to the spherical plain bearings 45. The spherical plain bearings 45 can not only adjust the total length of the shearing link 43 to ensure the motion accuracy and shearing accuracy of the shearing component 3, but also have a certain free margin while maintaining the motion accuracy, allowing a certain angular deviation of the shearing link 43, and enabling a certain machining error and installation error of the components of the present application.

[0066] On the basis of the above technical solution, the middle part of the mounting block 1 is connected to the shuttle receiving box 2 by bolts, and the tail of the mounting block 1 is pivotally connected to the shuttle receiving box 2.

[0067] When the cutting edge of the cutting component 3 becomes blunt and the cutting component 3 needs to be disassembled for replacement or regrinding of the cutting edge, this mounting block 1 is easier to disassemble; specifically, only one bolt needs to be removed to turn the mounting block 1 upwards, facilitating the disassembly of the cutting component 3.

[0068] As Figure 1 and Figure 4 shown, a guide block 7 is further provided at the front end of the bottom surface of the mounting block 1. A guide groove 71 is formed on the side surface of the guide block 7. The weft edge of the woven fabric 6 is inserted into the guide groove 71, and the outlet of the guide groove 71 is aligned with the cutting component 3.

[0069] The guide groove 71 of the guide block 7 can guide the weft edge to accurately enter the cutting edge of the cutting component 3, ensuring the cutting accuracy.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
