Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and more specifically, it relates to a carpet fabric composite processing equipment. Background Technology

[0002] Carpets, widely used in homes, cars, offices, and public spaces, are typically made by laminating a surface fabric with a backing substrate (such as non-woven fabric, rubber, foam, or anti-slip coating). Lamination is a key process for enhancing the carpet's structural strength, sound insulation, anti-slip properties, and lifespan. Currently, carpet fabric lamination often employs a pressing method, where the surface layer and the adhesive-coated backing are overlapped, and pressure is applied using rollers to bond and cure them.

[0003] A search revealed a Chinese patent document with authorization announcement number CN 217414926 U, which discloses a composite pressing device for carpet processing. The existing technology described above has the following drawbacks in use: The height adjustment of this device relies on manual rotation of the grip, making it impossible to precisely control the pressing force or gap. This can easily lead to over-pressing (damaging the fabric) or over-pressing (poor adhesion). Manual rotation depends on the operator's feel and visual inspection, making it impossible to accurately set or repeat the pressing gap, resulting in low adjustment precision and reduced product quality.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a carpet fabric composite processing equipment, which aims to solve the technical problems of low adjustment accuracy and low product quality.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a carpet fabric composite processing equipment, including a workbench, a fabric placement platform for carrying carpet fabric to be composited is fixedly installed on the upper end of the workbench, a feeding roller and a winding roller driven by a motor are respectively provided on the left and right sides of the upper end of the workbench, a through groove is opened in the horizontal direction at the front end of the fabric placement platform, a horizontally movable slide plate is slidably connected in the through groove, a fixing plate is fixedly installed on the front and rear sides of the upper end of the slide plate and on the front and rear sides of the fabric placement platform respectively, and vertical sliding grooves are fixedly installed on the opposite inner surfaces of the two fixing plates, a vertically arranged lead screw is movably connected in each sliding groove, a servo motor is fixedly connected to the top of the lead screw, an adjusting plate is threadedly connected to the outer surface of the two lead screws, a pressing wheel is fixedly installed at the lower end of the adjusting plate, a displacement sensor is provided on the front side of the pressing wheel, and a pressure sensor is fixedly installed at the lower end of the adjusting plate and directly above the pressing wheel.

[0007] The present invention is further configured such that: an electric cylinder is fixedly installed at the right end of the fabric placement platform, and the output end of the electric cylinder passes through the through groove and is fixedly connected to the slide plate.

[0008] The present invention is further configured such that: two guide rods are fixedly installed in the through groove, and the slide plate is slidably connected to the guide rods.

[0009] The present invention is further configured such that a dustproof plate is fixedly installed on the lower part of the groove.

[0010] The present invention is further configured such that: a positioning rod is rotatably connected to both the upper left and right sides of the workbench, which is located on the left and right sides of the fabric placement table.

[0011] The present invention is further configured such that the skateboard is made of wear-resistant engineering plastic.

[0012] The present invention is further configured such that the outer surface of the pressing wheel is covered with a silicone layer or a polyurethane layer.

[0013] In summary, this utility model has the following beneficial effects:

[0014] Two servo motors synchronously drive the lead screw to raise and lower the adjustment plate, replacing the manual grip and bevel gear mechanism in the original patent. With the help of a displacement sensor to detect the pressing gap in real time and a pressure sensor to monitor the pressing force in real time, the PLC controls the execution of a dual closed-loop strategy of "coarse position adjustment + fine pressure control". The pressing height and pressure can be set according to the process requirements and executed automatically. The adjustment accuracy is high, which solves the problem of pressing too tightly (damaging the fabric) or too loosely (poor adhesion) caused by manual adjustment errors, and significantly improves product consistency and yield.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] A carpet fabric composite processing equipment, such as Figures 1 to 2 As shown, the system includes a workbench 1, with a fabric placement platform 2 fixedly installed on the upper end of the workbench 1 to support the carpet fabric to be laminated. On the left and right sides of the upper end of the workbench 1, there are motor-driven feeding rollers 3 and take-up rollers 4, respectively. A horizontally oriented through groove 5 is formed at the front end of the fabric placement platform 2, within which a horizontally movable slide plate 6 is slidably connected. A fixing plate 7 is fixedly installed on the front and rear sides of the upper end of the slide plate 6, respectively, located on the front and rear sides of the fabric placement platform 2. Vertical sliding grooves 8 are fixedly installed on the opposing inner surfaces of the two fixing plates 7, and a vertically arranged lead screw 9 is movably connected within each sliding groove 8. The top of each lead screw 9... A servo motor 10 is fixedly connected, and an adjusting plate 11 is threadedly connected to the outer surfaces of two lead screws 9. A pressure wheel 12 is fixedly installed at the lower end of the adjusting plate 11. A displacement sensor 13 is provided on the front side of the pressure wheel 12. A pressure sensor 14 is fixedly installed at the lower end of the adjusting plate 11 and directly above the pressure wheel 12. An electric heating tube is embedded inside the pressure wheel 12, and flexible high-temperature resistant wires are led out from both ends of the tube. The wires are led out through the wire holes on the adjusting plate 11 and connected to an external power supply through a quick-connect connector. Since the pressure wheel 12 is fixedly installed at the lower end of the adjusting plate 11 and does not rotate, the wires do not need slip rings or rotary connectors, thus avoiding the risk of tangling.

[0023] like Figure 1 As shown, an electric cylinder 15 is fixedly installed at the right end of the fabric placement platform 2. The output end of the electric cylinder 15 passes through the through groove 5 and is fixedly connected to the slide plate 6. The electric cylinder 15 is an actuator that converts the rotary motion of an electric motor into linear push-pull motion. When its output end extends or retracts, it directly drives the slide plate 6, which is fixed to it, to move horizontally along the through groove 5, thereby realizing the overall horizontal movement of the pressing mechanism (including the pressing roller 12, adjusting plate 11, etc.) and adjusting the pressing position of the pressing roller 12 on the carpet fabric.

[0024] like Figure 1 As shown, two guide rods 16 are fixedly installed in the through groove 5. The slide plate 6 is slidably connected to the guide rods 16. The guide rods 16 are high-precision linear cylindrical rods. The slide plate 6 is fitted on them through linear bearings or sliding sleeves to form a low-friction, high-rigidity sliding pair, which provides the slide plate 6 with a stable and unbiased horizontal movement trajectory, preventing it from shaking or jamming under the push of the electric cylinder.

[0025] A dustproof plate 17 is fixedly installed at the bottom of the groove 8. The dustproof plate 17 is a thin plate structure that prevents fiber debris, dust or adhesive particles generated during carpet processing from entering the interior of the groove 8.

[0026] On the upper left and right sides of the workbench 1, and on the left and right sides of the fabric placement table 2, there is a positioning rod 18 that is rotatably connected. After the fabric is laid, the positioning rod 18 rotates downward and presses lightly on the left and right edges of the carpet to achieve lateral positioning and prevent the fabric from shifting during feeding or pressing.

[0027] The skateboard 6 is made of wear-resistant engineering plastics. Wear-resistant engineering plastics (such as polyoxymethylene POM, reinforced nylon PA66, polytetrafluoroethylene PTFE composite materials, etc.) have low coefficient of friction, high hardness, self-lubrication and fatigue resistance. When it is used with the guide rod 16, it forms a low-wear sliding pair. Long-term reciprocating motion is not prone to scratches or deformation.

[0028] The outer surface of the pressing roller 12 is covered with a silicone or polyurethane layer. Silicone or polyurethane (PU) is a highly elastic polymer material with a Shore hardness typically between A30 and A80. This buffers the pressing force, distributes the pressure evenly, and prevents the hard metal roller from directly contacting the carpet, causing indentations, carpet collapse, or fiber damage.

[0029] Working principle: The working process of the carpet fabric composite processing equipment described in this utility model is as follows: all components operate collaboratively under the unified coordination of a PLC controller (not shown in the figure, using an existing industrial PLC, such as Siemens S7-1200 or Mitsubishi FX5U):

[0030] The carpet top layer and bottom substrate (e.g., the top layer is nylon fleece, and the bottom layer is non-woven fabric coated with hot melt adhesive) are pre-wound on the feeding roller 3. After the drive motor of the feeding roller 3 is started, the top layer and bottom layer are released synchronously and laid flat on the upper surface of the fabric placement table 2. Since the two layers of materials share the same feeding roller, their initial alignment is good, reducing the risk of misalignment.

[0031] Positioning rods 18, driven by independent small motors, are installed on the upper left and right sides of the fabric placement platform 2. Once the top and bottom layers are laid in place, the PLC controls the positioning rods 18 to rotate downwards synchronously and gently press against the left and right edges of the carpet. The rotation of the positioning rods 18 not only achieves lateral positioning to prevent material displacement during subsequent pressing, but also initially bonds the top and bottom layers together through gentle pressure, eliminating air from the edges and providing a good foundation for subsequent hot-pressing lamination.

[0032] After the fabric is spread and laterally positioned, the PLC issues a command to extend the electric cylinder 15. The output end of the electric cylinder 15 is fixedly connected to the slide plate 6, pushing the slide plate 6 to slide horizontally along the two guide rods 16 in the through groove 5, so that the entire pressing mechanism (including the fixed plate 7, lead screw 9, servo motor 10, adjusting plate 11, and pressing roller 12) moves from the standby position to the pressing position directly above the fabric placement table 2.

[0033] The pressing roller 12 integrates an electric heating element (not shown) which is connected to an external power source via a flexible wire. Because the pressing roller 12 is designed as a non-rotatable structure (fixed to the lower end of the adjusting plate 11), it effectively avoids the problems of entanglement, wear, or breakage caused by the power cord moving with the traditional rotating pressure roller, thus improving the reliability of the equipment.

[0034] Before pressing, the PLC activates the electric heating element according to preset process parameters (such as a target temperature of 120°C) to raise the surface temperature of the pressing roller 12 to the set value. Subsequently, the PLC controls two servo motors 10 to rotate synchronously in the forward direction, driving two lead screws 9 to rotate, which in turn causes the adjusting plate 11 and the pressing roller 12 to descend vertically.

[0035] Displacement sensor 13: The optoNCDT ILR1191-2 laser displacement sensor from Micro-Epsilon, Germany, is installed on the front side of the pressing roller 12. The probe is vertically downward and aligned with the surface of the fabric placement table 2. It outputs the distance signal between the bottom of the pressing roller and the table surface in real time (sampling frequency ≥1kHz) through the laser triangulation measurement principle, which is used to accurately control the initial pressing gap.

[0036] Pressure sensor 14: It adopts the MFG series spoke-type load cell (model: MFG-500, range 0–500N) from Interface Corporation of the United States. It is fixed at the lower end of the adjustment plate 11 and directly above the mounting base of the pressing wheel 12. When the pressing wheel 12 contacts the carpet, the reaction force is transmitted to the pressure sensor 14 through the pressing wheel bracket. Its output analog voltage signal (0–10V) reflects the actual pressing force.

[0037] The PLC receives displacement and pressure signals and executes a dual closed-loop control strategy: In the coarse position adjustment stage, displacement sensor 13 acts as the main controller, quickly lowering the pressing roller 12 to near the target gap; in the fine pressure control stage, feedback is switched to pressure sensor 14, and the position of the servo motor 10 is finely adjusted using a PID algorithm to stabilize the pressing force at the set value (e.g., 350N±5N), achieving constant force hot pressing. This process ensures that carpets of different thicknesses achieve consistent bonding strength, avoiding damage from overpressure or delamination from underpressure.

[0038] After the pressing is completed (the holding time can be set), the servo motor 10 reverses and lifts the pressing roller 12; the electric cylinder 15 retracts and drives the slide plate 6 out of the pressing area; the take-up roller 4 starts to take up the carpet that has been laminated and prepares for the next cycle.

[0039] In summary, the invention employs two servo motors 10 to synchronously drive the lead screw 9 to raise and lower the adjusting plate 11, replacing the manual grip and bevel gear mechanism in the original patent. Combined with a displacement sensor 13 to detect the pressing gap in real time and a pressure sensor 14 to monitor the pressing force in real time, the PLC controls the execution of a dual closed-loop strategy of "coarse position adjustment + fine pressure control." Both the pressing height and pressure can be set according to process requirements and executed automatically, resulting in high adjustment accuracy. This solves the problems of excessively tight (damaging the fabric) or excessively loose (poor adhesion) pressing caused by manual adjustment errors, significantly improving product consistency and yield.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
