Description

Technical Field

[0001] This utility model relates to a transmission mechanism for a weaving machine, used to form knitted fabrics (such as sweaters and plackets), and belongs to the field of textile machinery technology. Background Technology

[0002] There are many types of electrically controlled ribbon weaving machines, and the weaving heads also come in single-head, double-head, and multi-head configurations, with various transmission methods. A common transmission method uses multiple sets of pulleys for speed regulation. However, this method cannot adjust the weaving speed for wide and narrow widths, consumes a lot of electricity, and is no longer suitable for modern needs. Furthermore, in traditional ribbon weaving machine transmission systems, the pulleys, sprockets, and chain rods—the moving connecting components of the weaving head—are separately assembled and installed on the front and rear sides of the machine. In particular, these components, especially those located on the front, occupy a large amount of space, making maintenance inconvenient and posing safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a transmission mechanism for a ribbon weaving machine that is compact, saves on consumables, and is safe and convenient to operate.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The transmission mechanism of the ribbon weaving machine includes a head assembly located on the front guide rail and the rear guide rail. The head assembly has one or more heads. When the head assembly has two or more heads, adjacent heads are connected together. Any head (rear triangular seat) is eccentrically connected to a sprocket via a chain rod. The sprocket is installed on the rear side of the ribbon weaving machine. When the sprocket rotates, it drives the head connected to it to move left and right via the chain rod. The sprocket is driven to rotate by a motor.

[0006] This invention integrates the transmission system, the speed-reducing pulley, and the sprocket of the adjustable weaving width mechanism into one optimized combination. This reduces the number of multiple speed-reducing pulleys, decreases intermediate transmission links, and reduces ineffective energy consumption. The optimized combination of belt sprockets, chain rods, and other head drive connecting components is installed at the rear of the weaving machine, efficiently utilizing the space at the rear and freeing up space at the front, making operation convenient and safe.

[0007] Preferably, the motor drives the sprocket to rotate via a belt. Specifically, the sprocket has a triangular groove on its side, the belt is a V-belt, and the motor drives the sprocket to rotate via the V-belt.

[0008] In order to adjust the left and right movement of the machine head (which can adjust the weaving speed to a certain extent), the sprocket is provided with a waist-shaped hole extending from the inside to the outside, and the connection point between the chain rod and the sprocket is located inside the waist-shaped hole.

[0009] The yarn guiding mechanism of the ribbon weaving machine is located on the front triangle seat of the machine head (or the rear triangle seat).

[0010] This utility model is easy to operate and maintain, safe and compact. It is equipped with a variable frequency motor control, adjustable weaving speed, and saves on consumables. It is more suitable for single-head, double-head and multi-head ribbon weaving machines. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] Figure 1 This is a rear view of the ribbon weaving machine.

[0013] Figure 2 This is a front view of a ribbon weaving machine. Detailed Implementation

[0014] like Figure 1 , 2 As shown, the transmission mechanism of the ribbon weaving machine includes a head assembly located on the front guide rail 3 and the rear guide rail 3'. The head assembly has two heads, left and right, which are connected together. The head is composed of a front triangular seat and a rear triangular seat. The front triangular seat on the front guide rail 3 and the rear triangular seat on the rear guide rail 3' are connected by a connector (such as the head connection method disclosed in patent document CN2486571Y).

[0015] Taking the rear view as an example, the rear triangular seat transmission connection component 5 of the right head 2 is eccentrically connected to the sprocket 7 via the chain rod 4. The sprocket 7 is installed on the rear side of the weaving machine. When the sprocket 7 rotates, it drives the head 2 connected to it (connected via the transmission component 5) to move left and right through the chain rod 4. At this time, both heads 2 on the front guide rail 3 and the rear guide rail 3' move.

[0016] The sprocket 7 is driven to rotate by a motor 8 (such as a variable frequency motor), and the motor 8 drives the sprocket 7 to rotate via a belt 9. Specifically, the sprocket 7 has a triangular groove on its side, the belt 9 is a V-belt, and the motor 8 drives the sprocket 7 to rotate via the V-belt.

[0017] To adjust the left-right movement range of the knitting head 2 (i.e., to adjust the weaving width), the sprocket 7 is provided with a waist-shaped hole 6 extending from the inside out. The connection point between the chain rod 4 and the sprocket 7 is located within the waist-shaped hole 6. The different connection points of the chain rod 4 and the sprocket 7 within the waist-shaped hole 6 determine the range of movement of the knitting head 2. At the same rotational speed, different connection points of the chain rod 4 and the sprocket 7 within the waist-shaped hole 6 result in different speeds for the knitting head 2, thus adjusting the weaving speed.

[0018] At this time, the yarn guiding mechanism 10 of the weaving machine is located on the front triangular seat of the machine head 2 (i.e., on the side of the front needle bed 1), and the installation position of the yarn guiding mechanism 10 is changed from the rear triangular seat of the machine head 2 to the front triangular seat of the machine head 2.

[0019] This invention optimizes the transmission system by combining the speed-redirecting pulley with a sprocket featuring an adjustable weaving width into a single belt sprocket. This belt sprocket directly drives the head unit via a chain rod. The head unit's transmission mechanism is located on the rear side of the weaving machine, allowing for unrestricted left-to-right or right-to-left oscillation. The transmission mechanism utilizes space at the rear of the weaving machine, freeing up space at the front and resulting in a compact design. The use of frequency converter control enables adjustable weaving speed, saving materials and ensuring safe and convenient operation. It can be adjusted to the optimal high-speed weaving state according to yarn and fabric requirements, improving weaving efficiency.

[0020] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
