Description

Technical Field

[0001] This utility model relates to the field of electronic jacquard machine technology, specifically to an energy-saving and consumption-reducing variable frequency speed control electronic jacquard machine. Background Technology

[0002] An electronic jacquard machine is a textile equipment developed using advanced computer control technology and opto-mechatronics technology. It is mainly used to produce jacquard fabrics with complex patterns. It was developed based on the traditional jacquard machine. Although it no longer uses an actual pattern stencil, the principle is similar. The pattern stencil file is stored in the control system of the electronic jacquard machine. For each weft, the control system sends instructions to the electronic needles according to the pattern stencil file information, which determines whether the warp yarns are raised or lowered, thereby forming the designed jacquard pattern.

[0003] Chinese Patent No. CN205347678U discloses a transmission mechanism for an electronic jacquard machine, belonging to the field of electronic jacquard machinery. It includes a machine body with a drive shaft mounted on it; each end of the drive shaft is connected to a transmission mechanism; each transmission mechanism is connected to a driven shaft; the driven shaft is connected to a lever assembly; and the lever assembly has a knife-lifting extension rod connected to both ends.

[0004] This patent uses a driven shaft to connect and drive the lever assembly, ensuring that all lever assemblies rotate at the same speed without deviation. While this improves the equipment's operating accuracy to some extent, this structure does not monitor the operating speed in real time during the jacquard process. There is no real-time data on the operating efficiency of the lever structure during its movement, making it impossible to adjust the operating efficiency of the electronic jacquard machine according to actual usage. The constant power operation results in high energy consumption. Therefore, an energy-saving and consumption-reducing variable frequency speed control electronic jacquard machine is proposed. Utility Model Content

It solves the problem that traditional electronic jacquard machines cannot adjust their operating efficiency according to actual usage conditions, and that constant power operation leads to high energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and consumption-reducing variable frequency speed control electronic jacquard machine, comprising a machine body, a drive component provided on the top of the machine body, a jacquard component provided below the drive component, and a control component used in conjunction with the drive component on the side of the machine body;

[0007] The drive assembly includes two fixed wall plates fixed to the top sides of the machine body. A drive motor is fixed to the side of the right fixed wall plate. A transmission box is fixed to the opposite side of the two fixed wall plates. A transmission shaft is rotatably connected above the two transmission boxes. A drive shaft and a driven shaft are rotatably connected below the two transmission boxes. A drive chain is engaged on the outside of the drive shaft, and a driven chain is engaged on the outside of the driven shaft.

[0008] The control assembly includes a main control module fixed on the right side of the machine body. Two fixed seats are fixed on the top of the machine body, and a guide roller is rotatably connected between the two fixed seats. A transmission cover is fixed on the left side of the machine body. One end of the guide roller is inserted into the transmission cover and rotatably connected to the transmission cover. A rotating disk is fixed to one end of the guide roller inside the right fixed seat. A reflective mark is fixed to the outside of the rotating disk. A speed sensor for use with the reflective mark is fixed inside the fixed seat.

[0009] Furthermore, the jacquard assembly includes four eccentric wheels fixed at both ends of the drive shaft and the driven shaft. A connecting crank is rotatably connected to the opposite side of the left and right eccentric wheels, and a knife holder is rotatably connected to the bottom of the connecting crank.

[0010] Furthermore, the back of the machine body is provided with a wire groove that runs through its front and rear sides. The wire groove has a cross structure, and an electronic jacquard needle integrated assembly with a solenoid valve structure is provided inside the wire groove. The electronic jacquard needle integrated assembly is laid parallel to the bottom groove of the wire groove inside the machine body.

[0011] Furthermore, the output shaft of the drive motor extends laterally through the fixed wall panel into the transmission box, and the output shaft of the drive motor is fixedly installed with the transmission shaft. Both ends of the drive shaft are connected to both ends of the driven shaft via driven chain transmission.

[0012] Furthermore, both ends of the transmission shaft are connected to both ends of the drive shaft via drive chains. Both the drive shaft and the driven shaft pass through the transmission box to the opposite side of the two transmission boxes, and the eccentric wheel is located on the opposite side of the two transmission boxes.

[0013] Furthermore, one end of the drive shaft passes through the fixed wall panel to the inside of the drive cover, and a gear is fixed on the outside of the drive shaft. The end of the guide roller located inside the drive cover is connected to the drive shaft via a chain.

[0014] Furthermore, the main control module is externally fixed to a housing that is fixedly installed with the machine body, the drive motor is electrically connected to the main control module, and the control module of the drive motor is located inside the housing of the main control module.

[0015] Furthermore, the side of the eccentric wheel is provided with several annularly distributed through holes, and the side opposite to the connecting crank is inserted into the through holes. The bottom of the knife holder is fixed with several evenly distributed knife holders, and the bottom of the knife holders has a V-shaped structure.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. This energy-saving and consumption-reducing variable frequency speed control electronic jacquard machine uses a drive motor to drive the transmission shaft to rotate. The drive chain and driven chain synchronously drive the drive shaft and driven shaft to rotate synchronously, thereby driving the eccentric wheels on both sides to rotate synchronously. The two eccentric wheels drive two connecting cranks to control the height of the lifting knife seat. The speed sensor and the rotating disk work together to monitor the current rotation speed of the guide roller. The main control module dynamically adjusts the output power of the drive motor according to the jacquard operation requirements to achieve the purpose of reducing energy consumption.

[0018] 2. This energy-saving and consumption-reducing variable frequency speed control electronic jacquard machine maintains the same rotation speed of the drive shaft and driven shaft through the drive chain and driven chain. At the same time, the transmission shaft synchronously drives the guide roller to rotate, so that the working efficiency of the lifting knife seat and the rotation frequency of the guide roller are synchronized. This allows for accurate monitoring of the actual power of the current drive motor, thus better matching it with the actual operation. Attached Figure Description

[0029] Please see Figure 1 and Figure 3 In this embodiment, the control component 4 includes a main control module 41 fixed on the right side of the body 1. Two fixed seats are fixed on the top of the body 1, and a guide roller 42 is rotatably connected between the two fixed seats. A transmission cover 43 is fixed on the left side of the body 1.

[0030] It should be noted that the speed sensor 45 is a non-contact photoelectric speed sensor, which is existing technology, and its specific working principle will not be explained in detail here.

[0031] In this embodiment, one end of the drive shaft 24 passes through the fixed wall panel 21 to the inside of the drive cover 43, and a gear is fixed on the outside of the drive shaft 24.

[0036] The working principle of the above embodiments is as follows:

[0037] The drive motor 22 is started to drive the transmission shaft 24 to rotate. The rotation of the transmission shaft 24 drives the drive shaft 25 to rotate through the drive chain 27. The rotation of the drive shaft 25 causes the driven chain 28 to drive the driven shaft 26 to rotate. The rotation of the drive shaft 25 and the driven shaft 26 causes the connecting crank 32 to drive the lifting knife seat 33 to move back and forth to a certain extent. This pushes the lifting knife at the bottom of the lifting knife seat 33 to press the wire harness passing below. The speed sensor 45 emits a beam of light and receives the reflected light on the rotating disk 44. When the reflective and non-reflective areas alternate, pulses are generated, which can monitor the rotation speed of the guide roller 42. The faster the rotation speed of the guide roller 42, the higher the current jacquard speed and the greater the power of the drive motor 22. The main control module 41 adjusts the working power of the drive motor 22 in real time, thus solving the problem that traditional electronic jacquard machines cannot adjust the working efficiency of the electronic jacquard machine according to the actual use and the constant power operation leads to high energy consumption.
