Description

Technical Field

[0001] This utility model relates to the field of chemical fiber cake clamping equipment, specifically an adaptive clamping mechanism for processing chemical fiber cakes. Background Technology

[0002] In the chemical fiber textile industry, chemical fiber cakes are a key intermediate product in the processing of chemical fiber filaments, and their processing quality directly affects the quality of subsequent textile products. The processing of chemical fiber cakes involves multiple stages, including winding, clamping, fixing, dyeing, and drying of the chemical fiber filaments. Among these, the clamping mechanism is the core component that enables precise positioning and stable transfer of the chemical fiber cake between each processing step. The production of chemical fiber cakes typically relies on automated winding machines to wind the chemical fiber filaments onto a drum, forming a cake with specific inner and outer diameters. After winding, the clamping mechanism is needed to transfer the chemical fiber cake from the winding station to subsequent processing stations (such as inspection, packaging, dyeing pretreatment, etc.), or to fix the chemical fiber cake in specific processing steps to ensure smooth processing.

[0003] Currently, most mainstream chemical fiber cake clamping mechanisms on the market are rigid clamping structures with fixed dimensions. These mechanisms are usually designed and manufactured according to the inner diameter of the chemical fiber cake roll of a specific specification, and their clamping range and clamping force cannot be adjusted according to the actual size of the chemical fiber cake being processed.

[0004] Furthermore, in pursuit of clamping stability, traditional fixed-size clamping mechanisms employ rigid contact clamping methods, which can easily generate hard friction with the inner wall of the chemical fiber cake roll during the clamping process. This can lead to damage to the roll surface and may even squeeze the outer layer of chemical fiber cake, causing problems such as cake deformation and filament breakage, which seriously affect the processing quality of the chemical fiber cake. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive clamping mechanism for processing chemical fiber cakes, which aims to improve the problems of poor adjustment flexibility and easy damage to chemical fiber filaments in existing chemical fiber cake clamping equipment.

[0006] This utility model is implemented as follows: An adaptive clamping mechanism for processing chemical fiber cakes includes a connecting frame. A multi-head seat plate is installed at the head of the connecting frame. Both ends of the multi-head seat plate are fixedly connected to the connecting frame. Several sets of clamping rods are inserted into the multi-head seat plate. One end of each clamping rod is fixedly connected to the multi-head seat plate. A clamping assembly is sleeved on the other end of each clamping rod. The clamping assembly includes a fixed end, a movable ring, and an X-shaped inner support frame. The fixed end is fixedly installed on the outer end of the clamping rod. The movable ring is sleeved on the clamping rod and slidably connected to it. The X-shaped inner support frame is disposed between the fixed end and the movable ring, and both ends of its bottom are rotatably connected to the fixed end and the movable ring, respectively. A driving assembly for driving the movable ring to move radially along the clamping rod is also installed on the multi-head seat plate.

[0007] Preferably, the connecting frame includes a connecting middle seat and a bent bracket for mounting the multi-head seat plate. The bent bracket is symmetrically installed on both sides of the connecting middle seat and is fixedly connected to the connecting middle seat.

[0008] Preferably, the multi-head seat plate includes a horizontal plate portion and a collar for mounting the clamping rod. The two ends of the horizontal plate portion are fixedly connected to the bending bracket. The collar is evenly installed on the outer side of the horizontal plate portion, and the collar is integrally formed with the horizontal plate portion.

[0009] Preferably, the fixed end includes an outer plate seat and a first connecting shaft for rotatably mounting the X-shaped inner support frame. The outer plate seat is evenly provided with several sets of side grooves along the circumferential direction, and the first connecting shaft is fixedly installed in the side grooves.

[0010] Preferably, the movable ring includes a ring seat and a second connecting shaft for rotatably mounting the X-shaped inner support frame. The ring seat is provided with several sets of transverse grooves evenly distributed along the circumferential direction, and the second connecting shaft is fixedly installed in the transverse grooves.

[0011] Preferably, the X-shaped inner support frame includes a first diagonal rod and a second diagonal rod, the middle part of the first diagonal rod is rotatably connected to the middle part of the second diagonal rod, and the lower end of the first diagonal rod is rotatably mounted on a first connecting shaft, the lower end of the second diagonal rod is rotatably mounted on a second connecting shaft, and a rubber ball is fixed to the head of both the first diagonal rod and the second diagonal rod.

[0012] Preferably, the drive assembly includes a push-pull frame, a positioning seat, and a support spring. The push-pull frame is slidably mounted on the horizontal plate, and an electric cylinder for driving the push-pull frame to move is fixedly mounted at the lower end of the horizontal plate. The positioning seat is inserted into the push-pull frame, and the support spring is installed between the positioning seat and the ring seat, with both ends of the support spring fixedly connected to the positioning seat and the ring seat, respectively.

[0013] Preferably, the push-pull frame includes a guide frame, a horizontal frame, and a U-shaped frame that cooperates with the positioning seat. The guide frame is slidably mounted on the horizontal plate, the horizontal frame is fixedly mounted on the outer end of the guide frame, and the U-shaped frame is evenly fixed on the horizontal frame.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application drives the movable ring to move through a drive component, enabling the X-shaped inner support frame to automatically adjust the clamping force and range according to the inner diameter of the chemical fiber cake roll, achieving adaptive clamping of chemical fiber cakes of different sizes and improving the versatility and applicability of the equipment. Simultaneously, the rubber ball at the head of the X-shaped inner support frame increases friction, preventing the cake from slipping and ensuring the stability and reliability of the clamping, thus improving the quality of chemical fiber cake processing. The elasticity of the rubber ball also prevents damage to the product, and the buffering effect of the support spring reduces the impact force during clamping. This clamping mechanism is simple to operate, can quickly and accurately clamp multiple sets of chemical fiber cakes, reduces the labor intensity of workers, and improves the efficiency of chemical fiber cake processing.

[0024] Example 1

[0025] Reference Figure 1 , Figure 2 and Figure 3An adaptive clamping mechanism for processing chemical fiber cakes includes a connecting frame 1. A multi-head seat plate 2 is installed at the head of the connecting frame 1. Both ends of the multi-head seat plate 2 are fixedly connected to the connecting frame 1. Several sets of clamping rods 3 are inserted into the multi-head seat plate 2. One end of the clamping rod 3 is fixedly connected to the multi-head seat plate 2. A clamping assembly 4 is sleeved on the other end of the clamping rod 3. The clamping assembly 4 includes a fixed end 41, a movable ring 42, and an X-shaped inner support frame 43. The fixed end 41 is fixedly installed on the outer end of the clamping rod 3. The movable ring 42 is sleeved on the clamping rod 3 and is slidably connected to the clamping rod 3. The X-shaped inner support frame 43 is disposed between the fixed end 41 and the movable ring 42. Both ends of the bottom of the X-shaped inner support frame 43 are rotatably connected to the fixed end 41 and the movable ring 42, respectively. A driving assembly 5 for driving the movable ring 42 to move radially along the clamping rod 3 is also installed on the multi-head seat plate 2. The connecting frame 1 is used to connect to external equipment, such as a robotic arm, for easy gripping and flexible transfer of the chemical fiber cake. A multi-head seat plate 2 is fixedly installed at the head, allowing for the installation of several sets of clamping rods 3 as needed. A sliding movable ring 42 and an X-shaped inner support frame 43 are provided on the clamping rod 3. The movable ring 42 is driven by the drive assembly 5, allowing the X-shaped inner support frame 43 to expand or contract. In actual use, it can be inserted into the roll of the chemical fiber cake. Driven by the drive assembly 5, the X-shaped inner support frame 43 is supported on the inner side of the roll, achieving stable clamping without damaging the wound chemical fiber. During use, the position of the movable ring 42 can be adjusted according to the inner diameter of the cake roll roll, thereby adjusting the clamping force and range, ensuring clamping stability and reliability, avoiding insecure clamping due to differences in cake size, and improving the quality and efficiency of chemical fiber cake processing. The connecting frame 1 includes a connecting base 11 and a bent bracket 12 for mounting the multi-head base plate 2. The bent bracket 12 is symmetrically installed on both sides of the connecting base 11 and is fixedly connected to the connecting base 11. The connecting frame 1, with its structural design of the connecting base 11 and bent bracket 12, provides a stable mounting foundation for the multi-head base plate 2. This structure enhances the overall strength and stability of the connecting frame 1, ensuring that it will not deform or shake due to uneven force during clamping, thus guaranteeing the normal operation of the entire clamping mechanism and improving the service life of the equipment.

[0026] Reference Figure 1 , Figure 2 and Figure 3The multi-head seat plate 2 includes a horizontal plate portion 21 and collars 22 for mounting the clamping rods 3. Both ends of the horizontal plate portion 21 are fixedly connected to the bending bracket 12. The collars 22 are evenly installed on the outer surface of the horizontal plate portion 21 and are integrally formed with the horizontal plate portion 21. This integral design of the horizontal plate portion 21 and collars 22 in the multi-head seat plate 2 not only ensures the integrity and stability of the structure, but also facilitates the installation and positioning of the clamping rods 3 by evenly distributing the collars 22 on the outer surface of the horizontal plate portion 21. During use, the clamping rods 3 can be evenly distributed on the multi-head seat plate 2, allowing each clamping component 4 to evenly clamp the chemical fiber cake, improving the balance and stability of the clamping, and thus improving the processing accuracy of the chemical fiber cake.

[0027] Example 2

[0028] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 An adaptive clamping mechanism for processing chemical fiber cakes includes a connecting frame 1. A multi-head seat plate 2 is installed at the head of the connecting frame 1. Both ends of the multi-head seat plate 2 are fixedly connected to the connecting frame 1. Several sets of clamping rods 3 are inserted into the multi-head seat plate 2. One end of the clamping rod 3 is fixedly connected to the multi-head seat plate 2. A clamping assembly 4 is sleeved on the other end of the clamping rod 3. The clamping assembly 4 includes a fixed end 41, a movable ring 42, and an X-shaped inner support frame 43. The fixed end 41 is fixedly installed on the outer end of the clamping rod 3. The movable ring 42 is sleeved on the clamping rod 3 and is slidably connected to the movable ring 42. The X-shaped inner support frame 43 is disposed between the fixed end 41 and the movable ring 42. Both ends of the bottom of the X-shaped inner support frame 43 are rotatably connected to the fixed end 41 and the movable ring 42, respectively. A driving assembly 5 for driving the movable ring 42 to move radially along the clamping rod 3 is also installed on the multi-head seat plate 2.

[0029] Reference Figure 4 and Figure 5 The fixed end 41 includes an outer plate seat 411 and a first connecting shaft 412 for rotatably mounting the X-shaped inner support frame 43. The outer plate seat 411 has several sets of side grooves evenly distributed along the circumference, and the first connecting shaft 412 is fixedly installed in the side grooves. The design of the outer plate seat 411 and the first connecting shaft 412 of the fixed end 41 provides reliable support and connection points for the rotation of the X-shaped inner support frame 43. The side grooves on the outer plate seat 411 can effectively limit the position of the first connecting shaft 412, ensuring the stability and accuracy of the X-shaped inner support frame 43 during rotation, so that the X-shaped inner support frame 43 can unfold and retract in a predetermined manner, achieving effective clamping of the chemical fiber cake.

[0030] Reference Figure 3 and Figure 5The movable ring 42 includes a ring seat 421 and a second connecting shaft 422 for rotatably mounting the X-shaped inner support frame 43. The ring seat 421 has several sets of transverse grooves evenly distributed along the circumference, and the second connecting shaft 422 is fixedly installed in the transverse grooves. The design of the ring seat 421 and the second connecting shaft 422 of the movable ring 42 allows the movable ring 42 to be flexibly connected to the X-shaped inner support frame 43 and to slide smoothly on the clamping rod 3. The transverse grooves on the ring seat 421 provide an installation position for the second connecting shaft 422, ensuring the stability of the rotational connection between the X-shaped inner support frame 43 and the movable ring 42. This allows the movement of the movable ring 42 to be accurately transmitted to the X-shaped inner support frame 43, achieving adaptive clamping of the chemical fiber cake.

[0031] Reference Figure 3 and Figure 5 The X-shaped inner support frame 43 includes a first inclined rod 431 and a second inclined rod 432. The middle part of the first inclined rod 431 is rotatably connected to the middle part of the second inclined rod 432, and the lower end of the first inclined rod 431 is rotatably mounted on a first connecting shaft 412. The lower end of the second inclined rod 432 is rotatably mounted on a second connecting shaft 422. Rubber balls 433 are fixed to the heads of both the first inclined rod 431 and the second inclined rod 432. The rotatable connection between the middle parts of the first inclined rod 431 and the second inclined rod 432 of the X-shaped inner support frame 43 allows the X-shaped inner support frame 43 to flexibly unfold and retract. The rubber balls 433 at the heads of the first inclined rod 431 and the second inclined rod 432 can increase the friction with the inner wall of the chemical fiber cake roll, preventing the cake from slipping during clamping. At the same time, the rubber balls 433 have a certain degree of elasticity, which can avoid damage to the cake and protect the quality of the chemical fiber cake.

[0032] Example 3

[0033] Reference Figure 3 and Figure 5 The drive assembly 5 includes a push-pull frame 51, a positioning seat 52, and a support spring 53. The push-pull frame 51 is slidably mounted on the horizontal plate 21, and an electric cylinder 20 for driving the push-pull frame 51 is fixedly mounted at the lower end of the horizontal plate 21. The positioning seat 52 is inserted into the push-pull frame 51, and the support spring 53 is installed between the positioning seat 52 and the ring seat 421, with both ends of the support spring 53 fixedly connected to the positioning seat 52 and the ring seat 421, respectively. The design of the push-pull frame 51, positioning seat 52, and support spring 53 in the drive assembly 5 allows the electric cylinder 20 to drive the push-pull frame 51 to move, thereby driving the movable ring 42 to move. The support spring 53 can buffer the impact force during the clamping process to a certain extent, protecting the equipment and the chemical fiber cake. At the same time, the support spring 53 can also automatically adjust the clamping force according to the actual situation of the yarn cake, realizing adaptive clamping and improving the flexibility and reliability of clamping.

[0034] Reference Figure 3 and Figure 5The push-pull frame 51 includes a guide frame 511, a transverse frame 512, and a U-shaped frame 513 that cooperates with the positioning seat 52. The guide frame 511 is slidably mounted on the horizontal plate 21, the transverse frame 512 is fixedly mounted on the outer end of the guide frame 511, and the U-shaped frame 513 is evenly fixed on the transverse frame 512. The structural design of the guide frame 511, transverse frame 512, and U-shaped frame 513 of the push-pull frame 51 ensures the accuracy of the sliding direction of the push-pull frame 51 on the horizontal plate 21. The transverse frame 512 provides the mounting base for the U-shaped frame 513. The U-shaped frame 513 cooperates with the positioning seat 52 to accurately transmit driving force, enabling the movable ring 42 to move in a predetermined manner, thereby ensuring the normal operation of the entire drive assembly 5 and achieving effective clamping of the chemical fiber cake.

[0035] Working Principle: In actual use, after the chemical fiber filaments are wound onto the spool, they form a chemical fiber cake. To avoid damaging the chemical fiber filaments, this equipment uses an internal clamping mechanism on the spool to hold the cake. When clamping the chemical fiber cake, the clamping rod 3 drives the clamping assembly 4 to insert into the spool of the chemical fiber cake. The electric cylinder 20 is activated, driving the push-pull frame 51 to slide on the horizontal plate 21. The push-pull frame 51, through the positioning seat 52 and the support spring 53, drives the movable ring 42 to move on the clamping rod 3. The movement of the movable ring 42 causes the X-shaped inner support frame 43 to unfold. When the rubber ball 433 of the X-shaped inner support frame 43 contacts the inner wall of the chemical fiber cake, the support spring 53 can adaptively clamp according to the inner diameter of the cake. After processing, the electric cylinder 20 reverses the drive of the push-pull frame 51, causing the movable ring 42 to move in the opposite direction, and the X-shaped inner support frame 43 to retract, releasing the clamp on the chemical fiber cake.

Various modifications and variations can be made to this utility model by those skilled in the art.
