Description

Technical Field

[0001] This utility model relates to the field of warp beam installation technology, and specifically discloses a quick loading and unloading structure for warp beams of a fiber warp car. Background Technology

[0002] The warp drive is a key piece of equipment in textile preparation, used to draw yarn from the bobbins on the bobbins and wind it onto the warp beam in a specified length and order, preparing it for the weaving process. As the core component that carries a large amount of yarn, the loading and unloading efficiency of the warp beam directly affects the production efficiency of the equipment and the labor intensity of the operators.

[0003] Traditional warp beam installation on fiber optic trolleys typically involves directly fixing the warp beam flange to the drive shaft flange using multiple bolts. This method is cumbersome, time-consuming, labor-intensive, requires tools, and demands high alignment precision from operators. Therefore, a quick-load and unload structure for the warp beams of fiber optic trolleys is needed to solve this problem. Utility Model Content

[0004] This invention proposes a quick-load and unload structure for warp beams on a fiber optic warp cart. Installation can be completed through a simple "push-rotate-lock" action. Disassembly only requires power off to demagnetize the electromagnet and rotate it slightly in the opposite direction to pop it out, which greatly improves the efficiency of warp beam replacement and reduces downtime.

[0005] This utility model is implemented as follows: a quick loading and unloading structure for the warp shaft of a warp cart includes a warp cart body. Mounting seats are provided on both the left and right sides of the inner wall of the warp cart body. Both mounting seats are rotatably connected to the warp cart body through bearings. One of the mounting seats is connected to the output end of an external drive motor. A warp shaft is provided between the two mounting seats. Mounting discs are fixedly connected to both the left and right sides of the warp shaft. Shaft heads are fixedly connected to the opposite sides of the two mounting discs. The two shaft heads and the mounting seats are detachably connected through a connecting structure.

[0006] The connection structure includes two slots on the outer wall of the shaft head, a hollow cavity on one side of the mounting base and adapted to the shaft head, two mounting slots on the inner wall of the hollow cavity, a locking rod inside the mounting slot and matching the slot, and a spring installed between one end of the locking rod and the mounting slot.

[0007] Electromagnets that can attract each other are embedded on the side of the mounting base near the shaft head and the side of the mounting plate.

[0008] As a preferred embodiment of the quick loading and unloading structure of the warp beam of the warp car of this utility model, a positioning block is fixedly connected to the opposite side of each of the two mounting discs, and a positioning groove matching the positioning block is opened on the opposite side of each of the two mounting seats.

[0009] As a preferred embodiment of the quick loading and unloading structure of the warp shaft of the warp car according to this utility model, both the end of the clamping rod and the opening of the clamping groove are arc-shaped.

[0010] As a preferred embodiment of the quick loading and unloading structure of the warp beam of the warp car according to this utility model, a storage battery for powering the electromagnet is embedded in the side of the mounting base near the mounting plate.

[0011] As a preferred embodiment of the quick loading and unloading structure of the warp beam of the fiber warping cart according to this utility model, the fiber warping cart body is provided with a switch for controlling the on and off of the electromagnet.

[0012] As a preferred embodiment of the quick loading and unloading structure of the warp shaft of the fiber warp cart according to the present invention, the depth of the hollow cavity is greater than the length of the shaft head insertion end, and one of the mounting seats has an opening on the front end face that communicates with the hollow cavity.

[0013] The beneficial effects of this utility model are:

[0014] Insert one end of the warp beam into the hollow cavity through the opening on the mounting base, and insert the other end into the hollow cavity on the mounting base and push it in. The end of the beam head presses against the arc-shaped end of the locking rod, causing it to compress the spring and retract into the mounting groove. When the locking groove on the beam head is rotated to align with the locking rod, the locking rod quickly pops out under the elastic force of the spring and locks into the locking groove. When the electromagnet is energized, the two attract each other, ensuring that the mounting plate and the mounting base fit tightly together, thus completing the installation of the warp beam. The installation can then be completed by connecting the structure and the electromagnet. When disassembling, simply turn off the power to demagnetize the electromagnet and rotate it slightly in the opposite direction to pop it out. This greatly improves the efficiency of replacing the warp beam and reduces downtime. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A quick-load and unload structure for the warp beam of a fiber warping cart includes a fiber warping cart body 1. Mounting seats 2 are provided on both the left and right sides of the inner wall of the fiber warping cart body 1. Both mounting seats 2 are rotatably connected to the fiber warping cart body 1 through bearings. One of the mounting seats 2 is connected to the output end of an external drive motor. A warp beam 3 is provided between the two mounting seats 2. Mounting discs 301 are fixedly connected to both the left and right sides of the warp beam 3. Shaft heads 302 are fixedly connected to the opposite sides of the two mounting discs 301. The two shaft heads 302 and the mounting seats 2 are detachably connected through a connecting structure.

[0022] The connection structure includes two slots 303 on the outer wall of the shaft head 302, a hollow cavity 201 on one side of the mounting base 2 and adapted to the shaft head 302, two mounting grooves 202 on the inner wall of the hollow cavity 201, a locking rod 204 inside the mounting groove 202 and matched with the slots 303, and a spring 203 installed between one end of the locking rod 204 and the mounting groove 202;

[0023] Electromagnets 4 that can attract each other are embedded in the side of the mounting base 2 near the shaft head 302 and the side of the mounting plate 301.

[0024] In this embodiment: when the warp shaft 3 needs to be installed, the operator inserts one end of the warp shaft 3 into the hollow cavity 201 through the opening on the mounting base 2, and inserts the other end into the hollow cavity 201 on the mounting base 2. At this time, the end of the shaft head 302 will squeeze the arc-shaped end of the locking rod 204, causing it to compress the spring 203 and retract into the mounting groove 202. During this process, when the locking groove 303 on the shaft head 302 rotates to align with the locking rod 204, the locking rod 204 will quickly pop out and lock into the locking groove 303 under the elastic force of the spring 203. In step 3, the electromagnet 4 on the mounting plate 301 and the electromagnet 4 on the mounting base 2 are brought close together. The operator energizes the electromagnet 4 through a switch, and the two attract each other, ensuring that the mounting plate 301 and the mounting base 2 are tightly fitted, thus completing the installation of the warp beam 3. After the warp beam 3 is installed, the drive motor can be started to work, and the installation can be completed by the connection structure and the electromagnet 4. When disassembling, it is only necessary to disconnect the power to demagnetize the electromagnet 4 and rotate it slightly in the opposite direction to pop it out, which greatly improves the efficiency of replacing the warp beam 3 and reduces downtime.

[0025] As a technical optimization of this utility model, positioning blocks 304 are fixedly connected to the opposite sides of the two mounting plates 301, and positioning grooves 205 matching the positioning blocks 304 are opened on the opposite sides of the two mounting seats 2.

[0026] In this embodiment, the positioning block 304 and the positioning groove 205 work together to ensure that the warp shaft 3 plays an auxiliary guiding role during installation.

[0027] As a technical optimization of this utility model, the end of the locking rod 204 and the opening of the locking groove 303 are both arc-shaped.

[0028] In this embodiment, the arc-shaped design ensures that when the shaft head 302 is inserted into the hollow cavity 201, the locking rod 204 contacts the outer wall of the shaft head 302 or the edge of the slot 303 with a smooth line contact or point contact. This allows the locking rod 204 to be easily squeezed back or guided into the slot, greatly reducing the operating force required for insertion and rotation.

[0029] As a technical optimization of this utility model, a storage battery for powering the electromagnet 4 is embedded in the side of the mounting base 2 near the mounting plate 301.

[0030] In this embodiment, a built-in battery is used to power the electromagnet 4, making the entire quick-change structure an independent module, thus avoiding safety hazards such as tangling, pulling, wear and leakage that may be caused by dragging the external power cord.

[0031] As a technical optimization of this utility model, the main body 1 of the fiber warp car is provided with a switch for controlling the on and off of the electromagnet 4.

[0032] In this embodiment: when installing or removing the warp beam 3, simply reach out and touch the special switch on the warp beam body 1 to turn the electromagnet 4 on or off.

[0033] As a technical optimization of this utility model, the depth of the hollow cavity 201 is greater than the length of the insertion end of the shaft head 302, and an opening communicating with the hollow cavity 201 is provided on the front end face of one of the mounting seats 2.

[0034] In this embodiment, the depth of the hollow cavity 201 is greater than the length of the insertion end of the shaft head 302, ensuring that even if the shaft head 302 is pushed all the way to the bottom, its end will not have a hard collision with the bottom of the hollow cavity 201, thus protecting the internal structure of the shaft head and the hollow cavity. The opening facilitates the removal of the warp shaft 3.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to install the warp shaft 3, the operator inserts one end of the warp shaft 3 into the hollow cavity 201 through the opening on the mounting base 2, and inserts the other end into the hollow cavity 201 on the mounting base 2. At this time, the end of the shaft head 302 will squeeze the arc-shaped end of the clamping rod 204, causing it to compress the spring 203 and retract into the mounting groove 202 (the opening diameter of the mounting groove 202 is smaller than the length of the end of the clamping rod 204 connected to the spring 203, which can prevent the clamping rod 204 from disengaging from the mounting groove 202). When the clamping groove 303 on the shaft head 302 rotates to align with the clamping rod 204, the clamping rod 204 is under the elastic force of the spring 203. Under the action of the mechanism, the warp beam 3 is quickly ejected and inserted into the slot 303. At the same time, the electromagnet 4 on the mounting plate 301 and the electromagnet 4 on the mounting base 2 approach each other. The operator energizes the electromagnet 4 through the switch, and the two attract each other, ensuring that the mounting plate 301 and the mounting base 2 fit tightly together, thus completing the installation of the warp beam 3. After the warp beam 3 is installed, the drive motor can be started to work. Then, the installation can be completed by connecting the structure and the electromagnet 4. When disassembling, it is only necessary to disconnect the power to demagnetize the electromagnet 4 and rotate the warp beam 3 in the opposite direction, so that the locking rod 204 pops out of the slot 303. Then, the warp beam 3 can be taken out with the opening. This greatly improves the efficiency of replacing the warp beam 3 and reduces downtime.
