Description

Technical Field

[0001] This utility model relates to the field of spandex yarn production technology, and in particular to a spandex yarn transport and fixing device. Background Technology

[0002] Spandex yarn, due to its excellent elasticity and stretchability, can be blended with different fibers as needed to create garments suitable for various occasions, making it widely used in textiles. After production, spandex yarn is generally collected into rolls using yarn bobbins. Workers typically collect it in collection baskets and place it on handcarts, or use carts with buckets to transport it to storage warehouses or textile production lines. However, using collection baskets or carts to stack spandex yarn rolls can easily cause localized deformation under pressure, affecting the quality of the spandex yarn.

[0003] To address the aforementioned technical problems, existing patent application number 201921082884.4 discloses a spandex yarn transport trolley. This device has multiple circumferentially fixed sleeves, and spandex yarn rolls are axially arranged side-by-side on these fixed sleeves, replacing the traditional stacking method. This avoids deformation of the spandex yarn under pressure. Furthermore, through the cooperation of a push rod motor and a piston push rod, the spandex yarn rolls can be pushed out of the fixed sleeves during unloading, reducing the workload of workers. In the above-mentioned prior art, the number of spandex yarn rolls that can be transported at one time is limited, resulting in relatively low transport efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a spandex yarn transport and fixing device to solve the problem of relatively low transfer efficiency of spandex yarn rolls.

[0005] To achieve the above objectives, this utility model provides a spandex yarn transport and fixing device, including a movable frame, on which two connecting mechanisms are arranged opposite each other, the connecting mechanisms including:

[0006] An L-shaped connecting arm is hinged to one side of the mobile frame, and one end of it is provided with a slot.

[0007] A locking block fixed to the mobile frame.

[0008] The elastic telescopic rod is vertically mounted on the movable frame and has a limiting groove at its top.

[0009] The fixing device also includes a reinforcing member located at the bottom of the mobile frame. The reinforcing member includes a U-shaped frame and an insert block fixed to the bottom of the mobile frame. The U-shaped frame and the mobile frame together form an insertion port.

[0010] During assembly, rotate the L-shaped connecting arm on one movable frame and engage its two ends with the limiting groove on it and the locking block on the other movable frame, respectively. At the same time, the insert block on one movable frame is inserted into the socket on the other movable frame to achieve fixed assembly.

[0011] Preferably, the width of the slot along the splicing direction of the movable frame is greater than the width of the top of the card block in the same direction, and the end of the slot away from the hinge point of the L-shaped connecting arm matches the card block on another movable frame.

[0012] Preferably, the boundary of the limiting groove and the boundary of the top of the elastic telescopic rod are rounded, and the shape and size of the limiting groove inside match the shape and size of the corresponding end of the L-shaped connecting arm.

[0013] Preferably, one end of the insert block located outside the movable frame matches the socket, and the orientation of the insert block is the same as the direction in which the movable frame is spliced ​​together.

[0014] Preferably, the elastic telescopic rod includes a sleeve rod and a slot axially disposed inside the sleeve rod. A slide rod is inserted inside the slot, and a compression spring is sleeved inside the slot. The two ends of the compression spring are respectively fixed to the slide rod and the inner wall of the slot.

[0015] Preferably, the fixing device further includes several vertical rods arranged horizontally in parallel within the movable frame, and several limiting parts are arranged in parallel along the axial direction on the outside of the vertical rods, the limiting parts being used to limit and fix the spandex yarn roll sleeved on the outside.

[0016] Preferably, the limiting part includes a horizontal support column fixed laterally to the vertical rod, and a through groove is provided radially at one end of the horizontal support column away from the vertical rod. A wedge block is slidably disposed in the through groove, and two elastic telescopic members are disposed opposite to each other between the two wedge blocks. The elastic telescopic members are used to radially push one end of the wedge block out of the through groove and limit and fix the spandex yarn roll.

[0017] Preferably, the structure of the elastic telescopic member is the same as that of the elastic telescopic rod, and the free end of the elastic telescopic member is fixed on the wedge block.

[0018] The beneficial effects of this utility model are:

[0019] This invention achieves rapid splicing of multiple mobile frames by rotating an L-shaped connecting arm on one frame downwards by 90°, so that one end of the L-shaped connecting arm is vertically engaged in the groove at the top of the limiting block on the mobile frame, and the other end of the L-shaped connecting arm is horizontally engaged in the top of the locking block on another mobile frame. At the same time, when two mobile frames are spliced ​​side by side, one end of the insert block at the bottom of one mobile frame is inserted into the U-shaped frame at the bottom of the other mobile frame, so that the connecting mechanism and the reinforcing member between the two spliced ​​mobile frames cooperate with each other, thereby increasing the number of spandex yarn rolls that can be transferred at one time, thus improving the overall transfer efficiency of spandex yarn rolls. It can also jointly constrain the degree of freedom and connection strength of adjacent two mobile frames in the horizontal direction during splicing. Attached Figure Description

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a spandex yarn transport and fixing device includes a movable frame 1. The movable frame 1 includes a support plate and casters located at the four corners of the bottom of the support plate. A gantry frame is fixedly mounted on the top of the support plate. Two connecting mechanisms 4 are arranged opposite each other on the movable frame 1, and the two connecting mechanisms 4 are respectively located on both sides of the gantry frame. The connecting mechanisms 4 include:

[0031] An L-shaped connecting arm 42 is hinged to one side of the movable frame 1, and one end of the arm is provided with a slot 43. The L-shaped connecting arm 42 is hinged to the gantry frame.

[0032] The locking block 41 is fixed on the movable frame 1. The locking block 41 and the L-shaped connecting arm 42 are located on the same side of the outside of the gantry frame and are arranged horizontally side by side. The end of the L-shaped connecting arm 42 with the locking groove 43 is initially vertically upward, which is the vertical end. The other end of the L-shaped connecting arm 42 is horizontal. When splicing, the vertical end of the L-shaped connecting arm 42 on one movable frame 1 deflects downward and drives the locking groove 43 to approach the locking block 41 on the other movable frame 1 until the locking groove 43 is fitted onto the top of the locking block 41 on the other movable frame 1. At this time, the opposing surfaces of the support plates of the two movable frames 1 are parallel and abut against each other.

[0033] An elastic telescopic rod 44 is vertically mounted on the movable frame 1. The elastic telescopic rod 44 includes a sleeve rod and a slot axially located inside the sleeve rod. The sleeve rod is vertically fixed to the outside of the gantry frame and is on the same plane as the L-shaped connecting arm 42. A sliding rod is inserted inside the slot. A compression spring is sleeved inside the slot. The two ends of the compression spring are fixed to the sliding rod and the inner wall of the slot, respectively. A limiting groove 45 is provided at the top of the spring. The free end of the sliding rod is always located outside the sleeve rod and vertically upward.

[0034] The fixing device also includes a reinforcing member 5 located at the bottom of the movable frame 1. The reinforcing member 5 includes a U-shaped frame 51 and a plug 53 fixed to the bottom of the movable frame 1. The U-shaped frame 51 and the movable frame 1 together form a socket 52. The orientation of the socket 52 is consistent with the direction of the two movable frames 1 being spliced ​​side by side. The U-shaped frame 51 and the plug 53 at the bottom of the same movable frame 1 are distributed opposite to each other.

[0035] During splicing, the L-shaped connecting arm 42 on one movable frame 1 is rotated so that its two ends are respectively engaged in the limiting groove 45 on it and the locking block 41 on the other movable frame 1. At the same time, the insertion block 53 on one movable frame 1 is inserted into the insertion port 52 on the other movable frame 1 to achieve fixed splicing. Through the mutual cooperation between the L-shaped connecting arm 42 on one movable frame 1 and the locking block 41 on the other movable frame 1, the degree of freedom between the two movable frames 1 in the lateral direction is constrained. Through the mutual cooperation between the insertion block 53 on one movable frame 1 and the insertion port 52 on the other movable frame 1, the degree of freedom between the two movable frames 1 in the longitudinal direction is constrained. This also makes the connecting mechanism 4 and the reinforcing member 5 between the two movable frames 1 interlock in the horizontal direction, improving the splicing connection firmness and stability between the two adjacent movable frames 1. Furthermore, multiple movable frames 1 can be spliced ​​together in sequence to achieve the transfer of more spandex yarn rolls at one time, thereby improving the overall transfer efficiency of spandex yarn rolls.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the width of the slot 43 along the splicing direction of the movable frame 1 is greater than the width of the top of the block 41 in the same direction. The end of the slot 43 away from the hinge point of the L-shaped connecting arm 42 matches the block 41 on another movable frame 1. With this design, when the vertical end of the L-shaped connecting arm 42 is deflected downward to a horizontal state, the slot 43 can be accurately fitted onto the top of the block 41 on another movable frame 1, and the block 41 is precisely engaged at the end of the slot 43 away from the hinge point of the L-shaped connecting arm 42. This improves the connection stability between the two adjacent movable frames 1 and avoids large gaps that would affect the splicing stability.

[0037] like Figure 4As shown, the boundary of the limiting groove 45 and the boundary of the top of the elastic telescopic rod 44 are rounded. The shape and size of the limiting groove 45 are matched with the shape and size of the corresponding end of the L-shaped connecting arm 42. This design is so that when the horizontal end of the L-shaped connecting arm 42 is deflected downward to a vertical state during splicing, the resistance of its horizontal end pressing down on the bottom end of the elastic telescopic rod 44 can be reduced. This allows the horizontal end of the L-shaped connecting arm 42 to be inserted into the limiting groove 45 at the top of the elastic telescopic rod 44, so that the deflected L-shaped connecting arm 42 is limited and fixed, its circumferential degree of freedom is constrained, and the L-shaped connecting arm 42 is locked, improving the connection firmness and stability between the two adjacent moving frames 1.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, one end of the insert 53 located outside the movable frame 1 matches the socket 52, and the orientation of the insert 53 is the same as the direction of the movable frame 1 when they are spliced ​​together. In this way, when multiple movable frames 1 are spliced ​​and fixed in sequence in a specified direction, the insert 53 can be inserted into the socket 52 on another adjacent movable frame 1 at the same time, which improves the neatness of the splicing and fixing of multiple movable frames 1 and works with the connecting mechanism 4 to constrain the degree of freedom and connection firmness between two adjacent movable frames 1 in the horizontal direction.

[0039] like Figures 1 to 3 As shown, the fixing device also includes several vertical rods 2 arranged horizontally in parallel within the movable frame 1. Several limiting parts 3 are arranged in parallel along the axial direction on the outside of the vertical rods 2. The limiting parts 3 are used to limit and fix the spandex yarn rolls sleeved on the outside.

[0040] The limiting part 3 includes a horizontal support column 31 fixed laterally to the vertical rod 2. The end of the horizontal support column 31 away from the vertical rod 2 is provided with a through groove 32. A wedge block 34 is slidably disposed in the through groove 32. The wedge block 34 is provided with an inclined surface, and the inclined surfaces on the two wedge blocks 34 are arranged to form a figure-eight shape. The end with the largest distance between the two inclined surfaces is close to the vertical rod 2. Two elastic telescopic members 33 are provided between the two wedge blocks 34. The elastic telescopic members 33 are used to radially push one end of the wedge block 34 out of the through groove 32 and limit and fix the spandex yarn roll.

[0041] The structure of the elastic telescopic member 33 is the same as that of the elastic telescopic rod 44, and the free end of the elastic telescopic member 33 is fixed on the wedge block 34.

[0042] With this design, when the spandex yarn roll is axially fitted onto the outside of the horizontal support 31, the horizontal thrust causes the spandex yarn roll to simultaneously press against the inclined surfaces of the two wedge blocks 34. This causes the wedge blocks 34 to contract into the groove 32 and compress the elastic telescopic member 33, accumulating elastic force until the wedge blocks 34 are completely retracted into the groove 32. At this point, the spandex yarn roll is completely fitted onto the outside of the horizontal support 31, and the inside of the spandex yarn roll passes completely through the port of the groove 32. Then, the wedge blocks 34 are pushed back to their original position by the accumulated elastic force of the elastic telescopic member 33, and the spandex yarn roll is fixed between the wedge blocks 34 and the outside of the vertical rod 2. This improves loading efficiency and also avoids direct contact between the spandex yarn rolls, which could affect the quality of the spandex yarn rolls, thus improving the protection effect of the spandex yarn rolls during transportation.

[0043] Working principle: Before transfer, the spandex yarn roll is axially fitted onto the outside of the horizontal support 31. Under the action of the horizontal thrust, the spandex yarn roll simultaneously squeezes the inclined surfaces on the two wedge blocks 34, causing the wedge blocks 34 to contract into the groove 32 and compress the elastic telescopic member 33, accumulating elastic force until the wedge blocks 34 are completely contracted into the groove 32. At this point, the spandex yarn roll is completely fitted onto the outside of the horizontal support 31, and the inside of the spandex yarn roll completely passes through the port of the groove 32. Then, the wedge blocks 34 are pushed back by the accumulated elastic force of the elastic telescopic member 33, thus limiting and fixing the spandex yarn roll between the wedge blocks 34 and the outside of the vertical rod 2. When it is necessary to remove the spandex yarn roll, the two wedge blocks 34 are pressed simultaneously and compressed. The spandex yarn roll can be fully retracted into the slot 32 and then pulled out. This increases the difficulty of loading or unloading the spandex yarn roll, improves the limiting and fixing effect of the spandex yarn roll, and can also avoid direct contact between spandex yarn rolls, which would affect the quality of the spandex yarn roll. It also improves the protection effect of the spandex yarn roll during the transfer process. After the mobile frame 1 is filled with spandex yarn rolls, multiple mobile frames 1 can be assembled side by side in a specified direction to increase the number of spandex yarn rolls transferred at one time and improve the overall transfer efficiency of spandex yarn rolls. The direction of the side-by-side assembly of multiple mobile frames 1 is as follows: the end of the L-shaped connecting arm 42 with the slot 43 is in a horizontal state with the opening of the slot 43 facing down. The direction pointed to by its end is the direction of the side-by-side assembly of multiple mobile frames 1.The specific assembly steps are as follows: First, place the two movable frames 1 side by side according to the assembly direction, aligning the L-shaped connecting arm 42 on one movable frame 1 with the locking block 41 on the other movable frame 1. Then, push the two movable frames 1 closer together and merge them. At this time, one end of the insert block 53 at the bottom of one movable frame 1 is inserted into the insert 52 at the bottom of the other movable frame 1. Then, deflect the L-shaped connecting arm 42 located between the two movable frames 1, and make its locking groove 43 gradually approach the top of the locking block 41 on the other movable frame 1 during the deflection, until the locking groove 43 on the L-shaped connecting arm 42 is fitted onto the top of the locking block 41, completing the locking between the two. At this time, the other end of the L-shaped connecting arm 42 abuts against the top of the elastic telescopic rod 44 in the latter half of the deflection action, and the top of the elastic telescopic rod 44 retracts downward under the action of the squeezing force, until the other end of the L-shaped connecting arm 42 is inserted into the limiting groove 45 at the top of the elastic telescopic rod 44. At the same time, the top of the elastic telescopic rod 44 springs back to its original position, realizing the locking of the L-shaped connecting arm 42. Locking: At this point, since the direction in which the insert block 53 is inserted into the socket 52 is consistent with the assembly direction of the moving frame 1, the socket 52 can constrain the degree of freedom of the insert block 53 in any horizontal direction other than the insertion direction. At the same time, the slot 43 constrains the degree of freedom of the slot block 41 in any horizontal direction other than the horizontal direction perpendicular to the splicing direction. In this way, the reinforcing member 5 and the connecting mechanism 4 can form an interlocking state, jointly constraining all degrees of freedom in the horizontal direction between two adjacent moving frames 1 after splicing, improving the connection firmness and stability between two adjacent moving frames 1 after splicing. Repeating this operation can assemble multiple moving frames 1 together in sequence, greatly increasing the number of spandex yarn rolls transferred at one time. During disassembly, simply press the top of the elastic telescopic rod 44 downward, so that one end of the L-shaped connecting arm 42 inserted at its top is disengaged from the inside of the limiting groove 45. Then, the L-shaped connecting arm 42 can be deflected in the opposite direction to reset, so that the slot 43 is deflected upward and disengaged from the top of the slot block 41. Then, the two moving frames 1 can be separated along the assembly direction.
