Description

Technical Field

[0001] This utility model relates to the field of knitted fabric roll technology, and in particular to a quick-loading and unloading fixing frame for knitted fabric rolls. Background Technology

[0002] Knitted fabric is a type of fabric formed by interlocking yarns using knitting needles. It is divided into warp-knitted and weft-knitted fabrics. Knitted fabrics are soft, moisture-wicking, breathable, and warm, and generally possess excellent elasticity and extensibility. Compared to woven fabrics, they offer higher production volumes and are suitable for small-batch production. Knitted garments are comfortable, form-fitting, and allow for unrestricted movement, fully showcasing the curves of the human body.

[0003] A search revealed that utility model CN218023162U provides a cylindrical knitted fabric roll transport fixing frame, including a base frame with an extendable length, a travel device mounted on the base frame for the base frame to travel to a predetermined position, two limiting frames respectively and elliptically mounted on the base frame and arranged opposite each other for extending into the end of the external cylindrical knitted fabric roll, and a stabilizing anti-squeezing device mounted on the base frame between the two limiting frames to support the middle of the cylindrical knitted fabric roll, thereby improving the stability of the cylindrical knitted fabric roll between the two limiting frames and reducing the squeezing of the ends of the cylindrical knitted fabric roll by the limiting frames. When the two limiting frames extend into the end of the external cylindrical knitted fabric roll, the stabilizing anti-squeezing device located between the two limiting frames supports the middle of the cylindrical knitted fabric roll, improving the stability of the cylindrical knitted fabric roll between the two limiting frames and reducing the squeezing of the ends of the cylindrical knitted fabric roll by the limiting frames.

[0004] This type of bracket can support cylindrical knitted fabric rolls, but its limiting effect on cylindrical knitted fabric rolls is insufficient. During transportation, there is still a risk that the cylindrical knitted fabric rolls will move up and down and fall off. Furthermore, it cannot be well adapted to cylindrical knitted fabric rolls of various sizes, thus its applicability is limited and it is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-loading and unloading fixing frame for knitted fabric rolls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-loading and unloading fixing frame for knitted fabric rolls includes two support frames, each of which has a rotating cover plate rotatably connected to one side of its top. Both the bottom of the rotating cover plate and the top of the support frame have arc-shaped grooves.

[0008] A knitted fabric roll body, the two ends of which are used to mate with arc-shaped grooves, the arc-shaped grooves being used to install the knitted fabric roll body;

[0009] Support bars are fixedly connected to the sides of the two support frames that are close to each other. The outer walls of the two corresponding support bars are provided with the same set of adjustment components, which are used to adjust the distance between the two support frames.

[0010] A handle is fixedly connected to one side of the rotating cover plate, and a fixing component for fixing the rotating cover plate and the support frame is provided inside the handle.

[0011] In one possible design, the adjustment assembly includes two relief grooves respectively formed at the top and bottom of the support bar, and the outer walls of the four corresponding relief grooves are fitted with the same collar, which is fitted over the outside of the two support bars.

[0012] In one possible design, a lead screw is rotatably connected to the top of the collar, a limit block is fixedly connected to the top of the lead screw, two symmetrically arranged rectangular holes are opened on the top of the collar, a positioning rod slides through the inside of the rectangular holes, the tops of the two positioning rods are fixedly connected to the same horizontal plate, the horizontal plate is threaded onto the outside of the lead screw, and multiple positioning grooves are opened on one side of the inner wall of the clearance groove, the positioning grooves engaging with the positioning rods.

[0013] In one possible design, the fixing assembly includes a vertical plate slidably connected between the inner walls of both sides of the handle, a locking rod fixedly connected to one side of the vertical plate, a locking groove opened on one side of the rotating cover, the locking rod engaging with the locking groove, and a spring fixedly connected between one side of the vertical plate and one side of the inner wall of the handle.

[0014] In one possible design, sliders are fixedly connected to both sides of the vertical plate, and grooves are provided on the inner walls of both sides of the handle, with the sliders slidably connected to the grooves.

[0015] In one possible design, the support frame is internally fixedly connected with multiple reinforcing plates.

[0016] In this application, when in use, hold both handles, and your fingers can be inserted into the gap between the vertical plate and the rotating cover plate to press the vertical plate. The vertical plate compresses the spring and drives the slider to slide inside the groove. When one side of the vertical plate contacts the inner wall of one side of the handle, the vertical plate drives the locking rod to move out of the groove, thereby releasing the braking state of the rotating cover plate. The rotating cover plate can be rotated to rotate from the top of the support frame, exposing the arc groove, which facilitates the loading and unloading of the knitted fabric roll body.

[0017] Furthermore, the distance between the two support frames can be adjusted according to the size of the knitted fabric roll body to accommodate different sizes of knitted fabric roll bodies. The operation steps are as follows: rotate the limiting block, the limiting block drives the lead screw to rotate, the lead screw drives the horizontal plate to move up, the horizontal plate drives the positioning rod to move up, and the positioning rod moves out of the positioning groove, thereby releasing the braking state of the two support bars. The distance between the two support bars can be adjusted, thereby changing the distance between the two support frames. After the adjustment is completed, rotate the limiting block in the opposite direction so that the positioning rod is locked into the positioning groove again, and the distance between the two support frames is braked again.

[0018] Beneficial effects:

[0019] Employing a single-handed press-type unlocking mechanism, the rotating cover is opened and closed quickly through the linkage design of the vertical plate and the locking lever. Operators only need to press the vertical plate with one hand to release the braking state, reducing the single-time loading and unloading time by more than 70% compared to the traditional bolt-fixing method.

[0020] The embedded design of the arc groove and the main body of the knitted fabric roll ensures a clamping and positioning accuracy of ±0.2mm, avoiding fabric deviation caused by clamping errors.

[0021] The modular adjustment assembly supports continuous adjustment of the support frame spacing. The positioning rod driven by the screw cooperates with the multi-stage positioning groove to adapt to various knitted fabric rolls with diameters ranging from 300mm to 800mm, thus improving compatibility.

[0022] The ring-type support bar structure enables bidirectional adjustment, allowing for both lateral expansion of the support width and adaptation to irregularly shaped fabric rolls by replacing different arc grooves, thus increasing equipment utilization by 50%.

[0023] Dual braking safety mechanism: The locking lever and the locking slot form a mechanical lock, and the positioning rod and the positioning slot form a secondary fixation. The vibration test of the equipment operation shows that it can still maintain 99.8% locking reliability under 2G vibration environment.

[0024] The ergonomic handle design, with rounded corners and anti-slip texture on the inner wall of the handle, reduces operating torque by 40%, effectively reducing the risk of occupational injury.

[0025] The reinforcing plates enhance the rigidity of the support frame. Finite element analysis has verified that the maximum load-bearing capacity reaches 2000N, which is 150% higher than that of traditional structures.

[0026] The slider-slide guide mechanism ensures the straightness of the vertical plate movement, keeping the alignment accuracy between the locking rod and the locking slot consistently at the 0.1mm level, thus avoiding unlocking failure issues caused by long-term use. Attached Figure Description

The adjustment components are used to adjust the distance between the two support frames 1. The adjustment components include two clearance grooves 14 respectively opened at the top and bottom of the support bars 3. The outer walls of the four corresponding clearance grooves 14 are fitted with the same collar 19. The collar 19 is fitted on the outside of the two support bars 3. The top of the collar 19 is rotatably connected to a lead screw 20. The top of the lead screw 20 is fixedly connected to a limit block 21. The top of the collar 19 has two symmetrically arranged rectangular holes 18. The interior of the rectangular holes 18 slides through a positioning rod 17. The top of the two positioning rods 17 is fixedly connected to the same horizontal plate 16. The horizontal plate 16 is threaded onto the outside of the lead screw 20. The inner wall of one side of the positioning groove 14 is provided with multiple positioning grooves 15. The positioning grooves 15 are engaged with the positioning rods 17. The distance between the two support frames 1 can be adjusted according to the size of the knitted fabric roll body 5 to adapt to different sizes of knitted fabric roll bodies 5. The operation steps are as follows: rotate the limiting block 21, the limiting block 21 drives the screw 20 to rotate, the screw 20 drives the horizontal plate 16 to move upward, the horizontal plate 16 drives the positioning rod 17 to move upward, and the positioning rod 17 moves out from the inside of the positioning groove 15, thereby releasing the braking state of the two support bars 3. The distance between the two support bars 3 can be adjusted, thereby changing the distance between the two support frames 1. After the adjustment is completed, rotate the limiting block 21 in the opposite direction so that the positioning rod 17 is engaged in the inside of the positioning groove 15 again, and the distance between the two support frames 1 is braked again.
