Description

Technical Field

[0001] This utility model belongs to the technical field of carpet laminating machines, specifically relating to a storage rack for carpet laminating and cutting lines. Background Technology

[0002] A carpet composite cutting line is a production line used for processing carpets. It mainly consists of a guide fabric storage rack, a conveyor belt, a cutting device, and a mold changing system. The guide fabric storage rack includes two parts: guide and storage. Guide is used to ensure accurate carpet cutting by feeding the carpet from the storage rack. A common guide device has a pair of rollers that move left and right in the middle according to the infrared signal to achieve correct cutting. The guide range is 0-200mm. The storage device is used to receive the carpet from the composite machine. The function of the storage rack is to feed the carpet intermittently during cutting. Since the composite material is continuous, a storage device is needed to ensure normal cutting. The storage length is set to 10 meters. However, infrared correction devices occupy a large area and are inconvenient. At the same time, existing fabric storage racks require the carpet to be passed through the storage shafts that are arranged alternately on the rack, which is cumbersome, time-consuming and labor-intensive. In addition, during the process of feeding and threading the fabric, the tension on each part of the carpet is uneven due to the manual operation, which can easily damage the carpet. Common fabric storage racks are fixed racks, which cannot control the tension on different thicknesses and quantities of fabric, nor can they control the feeding speed.

[0003] In summary, existing technologies suffer from problems such as large size of the correction device, inconvenience of use, uneven tension in the fabric storage device, and inability to control the feeding speed. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-6 This utility model will be described in further detail below.

[0025] Example 1, refer to Figure 1-6 In this embodiment, to address the problems of existing technologies such as large size of the correction device, inconvenience of use, uneven tension of the fabric storage device, and inability to control the feeding speed, this utility model discloses a fabric storage rack for carpet composite cutting lines. The rack includes a correction device and a fabric storage device. The fabric storage device includes a frame 6. An adjustment device 4 is connected to a fixing block 1 on the side of the frame 6 via an L-shaped support frame. A main covering roller 14 and a feeding shaft 13 are provided between two adjacent adjustment devices 4 on the side. An upper support frame 8 and a lower support frame 2 are connected to a guide rail with an aluminum base on the inner side of the frame 6 via a slider. A box 7 is provided above the frame 6. A gear shaft 11 is located inside the box 7, connected to a sprocket. A chain is connected to the sprocket, and the chain rests on a platform where the slider is located. A position sensor is also located on the platform. The correction device includes a support frame 20, with correction bases 22 on both sides of the support frame 20, connected in the middle by a first correction roller 19 and a second correction roller 21. The correction base 22 has a correction structure. The outer side where the housing 7 and the gear shaft 11 intersect is a cover 10. Two pairs of symmetrical bearing seats 9 are provided above the frame 6. There are multiple fixed connecting blocks inside the upper support frame 8 and the lower support frame 2. The upper covering roller 5 and the lower covering roller 3 are fixedly connected to the connecting blocks.

[0026] The position sensor is connected to the PLC controller. The position sensor generates a corresponding current by sensing the position of the upper support frame 8 and the lower support frame 2 and feeds it back to the PLC controller. The PLC controller adjusts the distance between the upper support frame 8 and the lower support frame 2 according to the amount of fabric. When the current generated by the position sensor is constant, the PLC controller controls the adjustment device 4 to make adjustments. This equipment is equipped with multiple upper covering rollers 5 and lower covering rollers 3 to ensure the tension of the carpet.

[0027] The main covering roller 14 is located above the feeding shaft 13. An L-shaped support frame has a sliding groove on its side, on which a driven roller seat 17 is mounted. The driven roller seat 17 is connected to the first cylinder 18 on top and to the main covering roller 14 on its inner side. A through hole is located below the sliding groove, and one side of the feeding shaft 13 is connected to a worm gear reducer 16 through the through hole. The worm gear reducer 16 is connected to a servo motor 15 on its lower side. A protective cover 12 is mounted above the covering roller 14 and is bolted to the L-shaped support frame.

[0028] Servo motor 15 drives worm gear reducer 16 to move, worm gear reducer 16 drives feeding shaft 13 to rotate, thereby driving carpet movement. Worm gear reducer 16 plays the role of matching speed and transmitting torque. The torque is transmitted to PLC controller through worm gear reducer 16. Position sensor feeds current back to PLC controller. PLC controller automatically adjusts the pneumatic precision pressure regulating valve according to current parameters to adjust the pressure of first cylinder 18 to complete the initial speed control. PLC controller compares the speeds of the two and controls first cylinder 18 to drive driven roller seat 17 to move up and down. Driven roller seat 17 drives main covering roller 14 to apply different forces to feeding shaft 13, further controlling speed and adjusting carpet tension. This ensures that carpet is fed with constant rated tension during traction, ensuring the qualified rate of cut finished products.

[0029] The straightening base 22 is offset outward at an angle of 45 degrees. Inside the straightening base 22, there are guide rods 23 on both sides. A movable block 25 is fitted onto the guide rod 23. The movable block 25 has an inverted U-groove in the middle. A piston rod 26 passes through the inverted U-groove and is fixed by a nut. The other side of the piston rod 26 is connected to the second cylinder 24 on the outside of the straightening base 22. A rotating seat 28 is movably connected above the movable block 25. The first straightening roller 19 and the second straightening roller 21 are fixed to the inner side of the rotating seat 28. The rotating seat 28 is connected to the straightening slide plate 29 below via a thrust ball bearing 27. The straightening slide plate 29 is mounted above the movable block 25.

[0030] Sensing materials are installed on the sides of the main covering roller 14, upper covering roller 5, and lower covering roller 3. When the sensing materials detect carpet deviation, they transmit data to the PLC controller. The PLC controller then adjusts the movement of the second cylinder 24. When the second cylinder 24 is activated, the movable rod 26 drives the edge-correcting slide plate 29 to move. The thrust ball bearing 27 on the edge-correcting slide plate 29 shifts due to the force, causing the rotating seat 28 to rotate. Because the rotating seat 28 is fixedly connected to the first edge-correcting roller 19 and the second edge-correcting roller 21, the first edge-correcting roller 19 and the second edge-correcting roller 21 will shift, thus ensuring that the carpet is centered on the cutting machine when it enters the storage rack. This equipment uses a 45-degree correction base 22, which is the maximum angle, facilitating the movement of the correction structure.

[0031] Specific implementation principle: When using this utility model, the position sensor feeds back the current to the PLC controller. The PLC controller drives the upper support frame 8 and the lower support frame 2 to move on the guide rail via sliders. When the upper covering roller 5 and the lower covering roller 3 sense the fabric data and transmit it to the PLC controller to determine the position, a constant current is generated between the position sensors. At this time, the PLC controller automatically adjusts the pneumatic precision pressure regulating valve to regulate the pressure of the first cylinder 18, initially limiting the distance between the main covering roller 14 and the feeding shaft 13, and activating the servo motor. Machine 15, feeding shaft 13 starts to rotate, real-time monitoring worm gear reducer 16 understands the rotation speed on both sides and adjusts it in real time. When the fabric deviates, the sensing materials on the sides of the main covering roller 14, upper covering roller 5 and lower covering roller 3 can sense the direction of deviation. The PLC controller will start the second cylinder 24 to extend and retract. When extending, the first edge-correcting roller 19 and the second edge-correcting roller 21 will shift to the right. When retracting, the first edge-correcting roller 19 and the second edge-correcting roller 21 will shift to the left to ensure that the carpet can be centered in the cutting machine when it enters the storage rack.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
