Description

Technical Field

[0001] The utility model relates to the technical field of cut pile and loop pile equipment, in particular to a head assembly of cut pile and loop pile equipment. Background Art

[0002] The cut pile loop pile equipment is a device used to root the pile yarn into the base cloth. In the process of the cut pile loop pile equipment currently on the market rooting the pile yarn into the base cloth, the needle in the head assembly of the cut pile loop pile equipment can root the pile yarn into the base cloth. After the pile yarn is rooted into the base cloth, the scissors in the head assembly of the cut pile loop pile equipment can cut the pile yarn between the base cloth and the needle. Through the continuous movement of the needle and the scissors, the head assembly can continuously root the pile yarn into the base cloth. However, in the head assembly of the cut pile loop pile equipment currently on the market, the drive of the needle and the scissors by the head assembly is realized by two independent drive components, so that there are disadvantages of complex structure of the head assembly and poor synchronization when the needle and the scissors move.

Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0014] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0015] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0016] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] See also Figure 1-4 As shown, the embodiment of the present application discloses a head assembly of a pile cutting and looping equipment, including a support sleeve 1, a support disk 2, scissors 3, a needle 4, a wire tube 5, a driving mechanism and two sliders 6; the support disk 2 is located below the support sleeve 1 and is fixed to the support sleeve 1, the wire tube 5 is passed through the support sleeve 1 and the support disk 2 and is used for the wool thread to pass through, the two sliders 6 are horizontally spaced and the two sliders 6 are vertically slidably connected between the support sleeve 1 and the support disk 2, the driving mechanism is connected to the support sleeve 1 and is used to drive the two sliders 6 to slide vertically alternately, and the upper end of the needle 4 is connected to one of them. A slider 6 is fixed, a through hole 41 is provided on the needle 4 for the wool thread from the wire tube 5 to pass through, a guide frame 7 is fixed on the support plate 2, the scissors 3 are vertically slidably connected to the guide frame 7, one of the rotating arms of the scissors 3 is fixed to the inner side of the other slider 6, and a protrusion 71 is provided on the side wall of the guide frame 7. When the slider 6 drives the scissors 3 to move downward, the protrusion 71 is used to squeeze the other rotating arm of the scissors 3 inward to close the scissors 3 and make the scissors 3 cut the wool thread between the base cloth and the needle 4. A presser foot 8 for pressing the base cloth is also fixed at the lower end of the support plate 2.

[0018] When the utility model is working, the presser foot is used to press tightly on the base cloth, and when the driving mechanism drives the slider connected to the needle to slide downward, the needle can penetrate into the base cloth and root the wool thread from the wire tube into the base cloth (at the same time, the slider connected to the scissors can slide upward and drive the scissors to move upward and reset). When the driving mechanism drives the slider connected to the scissors to slide downward, the scissors can first move downward with the slider, and when the lower end of the scissors moves to the wool thread between the base cloth and the needle, in the process of the scissors continuing to move downward, the other rotating arm of the scissors can move with the protruding part. When the two sliders are pressed against each other, the protrusion can press the other rotating arm of the scissors inward to close the scissors and cut the wool thread between the base cloth and the needle (at the same time, the slider connected to the needle can slide upward and drive the needle to move up and reset); in the process of the driving mechanism continuously driving the two sliders to slide back and forth alternately vertically, the needle and the scissors can move up and down alternately, and after the head assembly is assembled to the driving end of the moving mechanism, in the process of the moving mechanism driving the head assembly to move horizontally, the head assembly can continuously root the wool thread into the base cloth according to the pattern.

The two connecting rods 104 are dynamically connected, and the other end of each transmission rod 104 is rotationally connected to the other end of the connecting rod 103 on the corresponding side. By adopting this driving mechanism, when the driving motor is working, the driving motor can reliably drive the rotating shaft to rotate through the bevel gear set. Since one end of each connecting rod is respectively fixed to one end of the rotating shaft, and the two connecting rods are centrally symmetrically arranged relative to the rotating shaft, the angle difference between the two connecting rods can be kept at 180 degrees. When the two connecting rods drive the two sliders to slide via the two transmission rods, the two sliders can slide vertically back and forth alternately.

[0021] The driving mechanism also includes an encoder 106 and a controller; the encoder 106 is fixed on the support sleeve 1, and the encoder 106 is coaxially connected to the output shaft of the driving motor 101, and the driving motor 101 and the encoder 106 are both electrically connected to the controller; through the setting of the encoder, under the action of the encoder, when the driving motor needs to stop rotating, the controller can control the driving motor to stop after each rotation to a specific angle, so that the driving motor stops working after the needle moves to the bottom, so that the staff can pass the wool thread through the through hole on the needle.
