[0001] This utility model relates to the technical field of textile processing equipment, specifically to a textile processing and dyeing equipment that facilitates material feeding. Background Technology

[0002] Textile printing and dyeing equipment is used to process textiles through printing and dyeing. In textile printing and dyeing production, the feeding process is crucial. Proper feeding design can improve the efficiency of textile printing and dyeing equipment, and the design of the roll-changing device is a vital part of the feeding design. Traditional printing and dyeing equipment requires sequentially disassembling empty rolls and installing new rolls, which is inefficient and causes prolonged downtime. Therefore, developing a high-efficiency, accurate, cost-effective, and conveniently feeding textile processing and printing and dyeing equipment has become an urgent problem to be solved in the industry. Utility Model Content

[0003] The purpose of this invention is to provide a textile processing and dyeing equipment with convenient feeding, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A textile processing and dyeing equipment with convenient feeding includes a dyeing box, wherein a four-station roll changing device is provided at the feed inlet of the dyeing box, and the four-station roll changing device includes:

[0006] The rotating frame is composed of two sets of parallel ring supports that are fixedly connected by a central shaft and axial reinforcing rods.

[0007] The drive assembly includes a motor, which is connected to the annular support via a gear set and drives the rotating frame to rotate intermittently by 90 degrees.

[0008] The clamping mechanism includes a directional shaft assembly and a tapered guide head;

[0009] The directional shaft assembly is provided in four groups, evenly distributed at 90-degree intervals. Each group of directional shaft assembly includes two coaxially opposite directional shafts. The directional shafts are rotatably connected to the piston rod of the double-acting cylinder. The piston rod of the double-acting cylinder is slidably connected to the annular bracket through an axial sliding groove.

[0010] The tapered guide head is fixedly mounted on the end face of the orientation shaft, and it mates with the tapered cavity provided on the end face of the fabric core.

[0011] Preferably, a fixed baffle and a movable pressure plate are also sequentially provided on the directional shaft;

[0012] The fixed baffle is fixedly fitted onto the directional shaft;

[0013] The movable pressure plate slides with the keyway of the directional shaft, and a spring is provided between the movable pressure plate and the fixed stop plate.

[0014] Preferably, the end face of the movable pressure plate is provided with a radial first sawtooth, the first sawtooth is adapted to a second sawtooth, and the second sawtooth is provided on the end face of the core.

[0015] Preferably, the tooth profile angle of the first and second saw teeth is 60 degrees.

[0016] Preferably, the central shaft is rotatably connected to the support plate, and the gear set includes a gear ring disposed on any one of the annular bracket circumferential surfaces, the gear ring meshing with the gear, and the gear transmission connecting to the motor.

[0017] Preferably, an airflow chamber is formed inside the central shaft, the airflow chamber is connected to the double-acting cylinder through a pipe, and a solenoid valve is provided on the pipe; the airflow chamber is connected to an external air pressure source through a rotary joint.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This equipment features a four-station roll-changing device, achieving fully automatic roll changing with each 90-degree rotation. The four stations work in tandem; when the fabric at the unwinding station is depleted, a full roll of fabric from the preparation station is quickly transferred to the unwinding station, where a new roll immediately begins unwinding. Then, the fabric is detached from the core at the core-unwinding station, and finally, a new full roll of fabric is clamped at the clamping station. Compared to traditional manual roll changing, this significantly increases dyeing and printing output per unit time.

[0020] 2. By setting up the clamping assembly, the robotic arm delivers the core to the clamping station. Then, driven by a double-acting cylinder, the directional shaft causes the tapered guide head to insert into the tapered cavity of the core, while the movable pressure plate contacts the end face of the core. Once the tapered surfaces are tightly fitted, a spring pushes the radial serrations of the movable pressure plate to engage and lock tightly with the toothed grooves on the end face of the core.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution:

[0031] See Figure 1 A textile processing and dyeing equipment with convenient feeding, comprising a take-up shaft, a pinch roller, a guide roller, and a dyeing box 1. A four-station roll-changing device is installed at the feed inlet of the dyeing box 1. The four-station roll-changing device includes:

[0032] See Figure 2 , Figure 3 The rotating frame 2 includes two sets of parallel ring supports 21, which are fixedly connected by a central shaft 22 and an axial reinforcing rod 23.

[0033] See Figure 3 , Figure 4 , Figure 5 The drive component 3 includes a motor 31, which is connected to the ring bracket 21 through a gear 33 set and drives the rotating frame 2 to rotate intermittently by 90 degrees.

[0034] Clamping mechanism 4 includes a directional shaft 41 assembly and a tapered guide head 44;

[0035] The directional shaft 41 assembly is provided in four groups, evenly distributed at 90-degree intervals. Each group of directional shaft 41 assemblies includes two coaxial and opposite directional shafts 41. The directional shafts 41 are rotatably connected to the piston rod 42 of the double-acting cylinder. Specifically, the end face of the piston rod 42 is provided with an installation cavity. The directional shafts 41 are rotatably installed in the installation cavity through two sets of bearings 43. The piston rod 42 of the double-acting cylinder is slidably connected to the annular bracket 21, and a long strip-shaped slider is provided along the axial direction of the piston rod 42. A groove is provided on the annular bracket 21 corresponding to the slider to prevent the piston rod 42 from rotating during normal operation.

[0036] The tapered guide head 44 is fixedly set on the end face of the orientation shaft 41. It engages with the tapered cavity 51 set on the end face of the fabric core 5. While clamping the core 5, the tapered guide head 44 and the tapered cavity 51 of the core 5 can automatically correct the coaxiality.

[0037] The four-station roll changing device rotates clockwise one revolution starting from the side closest to dyeing box 1, as follows:

[0038] At the unwinding station, the fabric is unwound under the drive of the take-up shaft.

[0039] At the core unloading station, the corresponding double-acting cylinder moves, the piston rod 42 retracts and drives the directional shaft 41 to move, and the empty core 5 is released from the clamping mechanism 4 under the action of gravity.

[0040] At the clamping station, the robotic arm conveys a full roll and aligns it with the clamping mechanism 4. Then, the corresponding double-acting cylinder moves, and the opposite conical guide head 44 inserts into the conical cavity 51 of the roll core 5. The clamping work is completed through the conical surface cooperation. The robotic arm and its alignment and positioning technology with the clamping mechanism 4 used in this application are existing knowledge of robotic arms in automated equipment.

[0041] The standby station is in standby mode, with a full roll of fabric in the ready position.

[0042] See Figure 4 , Figure 5 and Figure 6 The directional shaft 41 is also provided with a fixed baffle 45 and a movable pressure plate 46 in sequence.

[0043] The fixed baffle 45 is fixedly mounted on the directional shaft 41;

[0044] The movable pressure plate 46 is slidably fitted with the keyway of the directional shaft 41, and a spring 47 is provided between the movable pressure plate 46 and the fixed stop plate 45. One end of the spring 47 is fixedly connected to the end face of the movable pressure plate 46, and the other end is fixedly connected to the end face of the fixed stop plate 45.

[0045] The end face of the movable pressure plate 46 is provided with a radial first sawtooth 48, which is adapted to the second sawtooth 52. The second sawtooth 52 is provided on the end face of the core 5. After clamping, the spring 47 is compressed, and the first sawtooth 48 and the second sawtooth 52 are kept in a tightly meshed state under the action of the spring 47, thereby further preventing relative rotation between the core 5 and the directional shaft 41 or the movable pressure plate 46.

[0046] The tooth profile angles of the first sawtooth 48 and the second sawtooth 52 are 60 degrees, balancing strength and meshing sensitivity.

[0047] The central shaft 22 is rotatably connected to the support plate 6. The gear 33 group includes a gear ring 32 set on the circumferential surface of any one set of annular brackets 21. The gear ring 32 meshes with the gear 33, and the gear 33 is connected to the motor 31 for transmission.

[0048] See Figure 7 An airflow chamber is opened inside the central shaft 22. The airflow chamber is connected to a double-acting cylinder through a pipe 7, and a solenoid valve 8 is provided on the pipe 7.

[0049] The airflow chamber is connected to an external air pressure source via a rotary joint.

[0050] Using this utility model:

[0051] The status of each workstation during normal operation:

[0052] Workstation A (i.e., preparatory workstation): Loaded with a full roll of fabric, ready for use.

[0053] Station B (i.e., unwinding station): Fabric is being unwound.

[0054] Station C (i.e., core unloading station): Unloaded (core 5 disengages from clamping mechanism 4)

[0055] Station D (i.e., clamping station): Loaded with a full roll of fabric, ready for use.

[0056] Volume swap trigger:

[0057] When the fabric at workstation B is exhausted, control motor 31 activates, driving the frame to rotate 90 degrees.

[0058] Workstation A is moved to the unwinding workstation, and the new roll begins to be unwound. Workstation D is moved to the preparation workstation.

[0059] Workstation B is switched to the core unloading 5 workstation, and the corresponding double-acting cylinder is controlled to retract the piston rod 42, and the core 5 is dislodged;

[0060] Workstation C transitions to the clamping station to perform fabric clamping. The specific process for clamping a full roll of fabric is as follows:

[0061] The robotic arm delivers the core 5 to the winding station, and the core 5 is aligned with the center line of the orientation axis 41;

[0062] The double-acting cylinder actuates, pushing the directional shaft 41 to insert the tapered guide head 44 into the mounting hole. After the movable pressure plate 46 contacts the end face of the core 5, it stops moving. The directional shaft 41 continues to move forward to compress the spring 47. When the tapered surfaces are tightly fitted, the spring 47 pushes the radial serrations of the movable pressure plate 46 to tightly mesh and lock with the tooth grooves on the end face of the core 5. At the same time, the tapered guide head 44, in conjunction with the tapered cavity 51 of the core 5, can automatically correct the coaxiality.

[0063] In this way, a fully automatic roll change is achieved every 90 degrees of rotation, with four workstations working together to greatly improve the efficiency of roll changing.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
