Description

Technical Field

[0001] This utility model relates to the field of edge frame technology for flat knitting machines, and more specifically, to edge frame for computer flat knitting machines. Background Technology

[0002] Currently, the selvage frame of a computerized flat knitting machine is a device for adjusting the yarn tension. Computerized flat knitting machines are further divided into various needle types according to coarse needles and fine needles, and the yarn tension of each needle type is different.

[0003] Modern edge thread frames are all installed facing upwards, that is, above the yarn thread opening. The tension of the yarn is mainly adjusted by the tensioning parts and elastic parts on the edge thread frame. Due to the limitation of the height of the flat knitting machine, the size of the edge thread frame cannot be significantly modified.

[0004] The current yarn breakage alarm on the edge frame mainly relies on a pull rod, a stop bar, and a sensor. The pull rod is equipped with a stop bar on top, and a magnet is installed on one side of the stop bar. The sensor is installed on the side with the magnet. When the yarn breaks, the pull rod will rotate upward, which will push the stop bar to rotate as well. When the magnet on the stop bar reaches the sensor position, the alarm is triggered. The force for the pull rod to rotate is provided by an elastic element. If the force of the elastic element is too small, it will not be able to push the stop bar to the sensor position, and the alarm action will not be completed. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a side frame for a computerized flat knitting machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a side thread frame for a computerized flat knitting machine, comprising a side thread frame plate, a sensor, an elastic element, a thread pulling assembly, a baffle, and a mounting shaft. The thread pulling assembly is movably mounted on the side thread frame plate for pulling the yarn. The thread pulling assembly includes a thread pulling element and a mounting base. The mounting base is movably mounted on the side thread frame plate. The baffle and the mounting shaft are both mounted on the side thread frame plate. The mounting base is rotatably sleeved outside the mounting shaft. One end of the elastic element is fixed to the bottom of the mounting base, and the other end is connected to the side thread frame plate, and the elastic element is in a stretched state. The sensor is mounted on the baffle for detecting the displacement of the mounting base after yarn breakage. The bottom end of the thread pulling element is fixed to the mounting base, and its top end is provided with a thread-passing hole. The elastic element can be a tension spring or an elastic rope.

[0007] By adopting the above technical solution, the yarn passes through the threading hole. The puller and the mounting base are maintained in a relatively stable state and away from the baffle through the combined action of the yarn and the elastic element. When the yarn breaks, the elastic element resets and drives the mounting base to rotate outward. The mounting base rotates directly to fit against the baffle. At this time, the sensor directly detects the mounting base, thereby realizing the alarm action.

[0008] The present invention is further configured such that the sensor is a through-beam sensor, with its transmitter and receiver respectively installed at both ends of the baffle, and the mounting base is located between the transmitter and receiver of the sensor. When the mounting base is in contact with the baffle, the receiver of the sensor cannot receive the signal emitted by the transmitter. When the mounting base is away from the baffle, the receiver of the sensor can receive the signal emitted by the transmitter.

[0009] The present invention is further configured such that the side frame also includes an adjustment component, which includes an adjustment slider and a first fastener. The adjustment slider has a first threaded hole that mates with the first fastener, and the side frame plate has a through groove. The head of the first fastener and the adjusting slider are respectively attached to the two sides of the edge frame plate, and the rod of the first fastener passes through the through groove and mates with the first threaded hole of the adjusting slider. The rod of the first fastener passes through the first threaded hole and is connected to the top of the elastic element. The first fastener can be a bolt, screw, or screw.

[0010] The present invention is further configured such that there are several mounting seats and pull wire components, and several mounting seats are spaced apart and sleeved on the outside of the mounting shaft. Both sides of the mounting seat are provided with snap rings, and the mounting shaft is provided with snap ring grooves corresponding to the snap rings. The snap rings and snap ring grooves are engaged and cooperated to limit the mounting seats in the axial direction of the mounting shaft.

[0011] The present invention is further provided that the outer sleeve of the pull wire component is provided with a sleeve.

[0012] The present invention is further configured such that the adjusting slider has a limiting part on the side facing the through groove, and the limiting part is located inside the through groove and fits against the inner wall of the through groove.

[0013] The present invention is further configured such that both ends of the baffle are rotatably sleeved outside the mounting shaft, and there is a fixing component between the baffle and the side frame plate for fixing the baffle.

[0014] The present invention is further configured such that the fixing component includes a second fastener, a second threaded hole is provided on the edge frame plate, an arc-shaped groove corresponding to the second threaded hole is provided on the baffle plate, the rod portion of the second fastener passes through the arc-shaped groove and is threadedly connected to the second threaded hole, and the baffle plate is clamped between the edge frame plate and the head of the second fastener. The second fastener can be a bolt, screw, or screw.

[0015] Compared with the prior art, this utility model provides a side frame for a computerized flat knitting machine, which has the following advantages: 1. The sensor directly detects the mounting base. Once the yarn breaks, the mounting base rotates directly to the sensor position under the action of the elastic element, reducing the probability of alarm failure.

[0016] 2. The edge thread frame provided in this utility model increases the size of the edge thread frame by installing it below the yarn thread opening, extends the length of the pull thread component and the elastic component, and increases the tensile force.

[0017] 3. The lever design has been eliminated in this utility model. The elastic element only needs to pull the mounting base to rotate, which further reduces the possibility of the alarm not working. Attached Figure Description

Example 1

[0024] A side frame for a computerized flat knitting machine includes a side frame plate 1, a sensor 2, an adjustment assembly 3, an elastic element 9, a pull wire component 4, a mounting base 5, a baffle 6, and a mounting shaft 7. Both the baffle 6 and the mounting shaft 7 are mounted on the side frame plate 1. The transmitter and receiver of the sensor 2 are correspondingly mounted at opposite ends of the baffle 6 to detect the mounting base 5. The mounting base 5 is rotatably sleeved around the mounting shaft 7. When the mounting base 5 is in contact with the baffle 6, the receiver of the sensor 2 cannot receive the signal emitted by the transmitter. When the mounting base 5 is away from the baffle 6, the receiver of the sensor 2 can receive the signal emitted by the transmitter. One end of the elastic element 9 is fixed to the bottom of the mounting base 5, and the other end is mounted on the side frame plate 1, with the elastic element 9 in a stretched state. The bottom end of the pull wire component 4 is fixed to the mounting base 5, and its top end has a thread hole 8. The pull wire component 4 is covered with a sleeve 10. Preferably, the elastic element 9 is a tension spring.

[0025] In specific applications, sensor 2 can be a through-beam photoelectric sensor, whose transmitter emits infrared light and the receiver receives the infrared light. Sensor 2 is electrically connected to the peripheral control device and exchanges signals. When the yarn breaks, the elastic element 9 drives the mounting base 5 to rotate. The mounting base 5 rotates directly to fit against the baffle 6 and is located between the transmitter and receiver of the through-beam photoelectric sensor. The receiver cannot receive the infrared light emitted by the transmitter, and the peripheral control device obtains the signal and issues an alarm.

[0026] In specific applications, sensor 2 can also be a through-beam ultrasonic sensor, whose transmitter emits ultrasonic signals and the receiver receives the ultrasonic signals. Sensor 2 is electrically connected to the external control device and exchanges signals. When the yarn breaks, the mounting base 5 rotates directly to fit against the baffle 6. At this time, the ultrasonic signal emitted by the transmitter of the through-beam ultrasonic sensor is blocked by the mounting base 5, and the receiver cannot receive the ultrasonic signal emitted by the transmitter. The external control device obtains the signal and triggers an alarm.

[0027] In this embodiment, the adjustment component 3 includes an adjustment slider 301 and a first fastener 302. The adjustment slider 301 has a first threaded hole 303 that mates with the first fastener 302. The side frame plate 1 has a through groove 304. The head of the first fastener 302 and the adjustment slider 301 are respectively attached to the two sides of the side frame plate 1. The rod of the first fastener 302 passes through the through groove 304 and mates with the first threaded hole 303 of the adjustment slider 301. The rod of the first fastener 302 passes through the first threaded hole 303 and is connected to the top of the elastic member 9. The side of the adjustment slider 301 facing the through groove 304 has a limiting part 305, and the limiting part 305 is located in the through groove 304 and is attached to the inner wall of the through groove 304. The first fastener 302 can be a screw, bolt, or bolt.

[0028] In practical applications, the tension of the elastic element 9 is adjusted according to the requirements of the yarn type to adjust the tension of the yarn puller 4 on the yarn. When it is necessary to adjust the tension of the elastic element 9, the first fastener 302 is loosened, the adjusting slider 301 is moved up and down until it moves to the appropriate position, and then the first fastener 302 is tightened. By adjusting the friction between the head of the slider 301, the first fastener 302 and the edge wire frame plate 1, the adjusting slider 301 is fixed.

[0029] In this embodiment, several mounting bases 5 and pull wire parts 4 are provided, and several mounting bases 5 are spaced out on the outside of the mounting shaft 7. Both sides of the mounting base 5 are provided with snap rings 1302, and the mounting shaft 7 is provided with snap ring grooves 1301 corresponding to the snap rings 1302. The snap rings 1302 and snap ring grooves 1301 cooperate to form a limiting structure, which is used to limit the mounting base 5 in the axial direction of the mounting shaft 7.

[0030] In practical applications, the snap ring 1302 is fixed in the snap ring groove 1301 on both sides of the mounting base 5 to limit the mounting base 5 in the axial direction of the mounting shaft 7.

[0031] In this embodiment, the two ends of the baffle 6 are rotatably sleeved on the mounting shaft 7. There is a fixing component 11 between the baffle 6 and the side frame plate 1 for fixing the baffle 6. The fixing component 11 includes a second fastener 1101. The side frame plate 1 has a second threaded hole 1102. The baffle 6 has an arc-shaped groove 1103 corresponding to the second threaded hole 1102. The rod of the second fastener 1101 passes through the arc-shaped groove 1103 and is threadedly connected to the second threaded hole 1102. The baffle 6 is clamped between the side frame plate 1 and the head of the second fastener 1101. The second fastener 1101 can be a screw, bolt or bolt.

[0032] In practical applications, the distance between the baffle 6 and the mounting base 5 is adjusted according to the requirements. When adjusting, first loosen the second fastener 1101, move the baffle 6 to rotate around the mounting shaft 7. At this time, the position of the second fastener 1101 is fixed, and the second fastener 1101 moves relative to the baffle 6 in the arc groove 1103 until the baffle 6 moves to the appropriate position. Then tighten the second fastener 1101 to fix the baffle 6. Example 2

[0033] The difference from Embodiment 1 is that the sensor 2 is a pressure sensor, which is installed on the side of the baffle 6 facing the mounting base 5. When the yarn breaks, the mounting base 5 shifts and adheres to the surface of the baffle 6. At this time, the pressure sensor receives a pressure signal and triggers an alarm.

[0034] In all the solutions mentioned above, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
