[0052] Next, in combination with the attached drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0053] Please refer to Figures 1-9 , in the embodiments of the present utility model, a knitting electronic stretching machine includes

[0054] A transmission component 4, and the transmission component 4 for driving the sliding fabric clamping component 6 is installed inside the machine housing 1;

[0055] The fixed fabric clamping component 5, which is used for fixing knitted fabrics and is fixed at one end outside the machine housing 1, is used in cooperation with the sliding fabric clamping component 6. The sliding fabric clamping component 6 is slidably connected to the outside of the machine housing 1 and is in transmission connection with the transmission component 4.

[0056] The measuring tape 7, which is used to measure the elongation length of the knitted fabric, is arranged inside the machine housing 1, and the measuring tape 7 expands or contracts following the movement of the sliding fabric clamping component 6.

[0057] By adopting the above technical solution, when in use, first clamp one end of the knitted fabric on the fixed fabric clamping component 5 and the other end on the sliding fabric clamping component 6. Then, drive the sliding fabric clamping component 6 to slide through the transmission component 4 to realize the stretching of the knitted fabric. While the knitted fabric is being stretched, the measuring tape 7 gradually expands, and the measuring tape 7 extends as long as the knitted fabric is stretched, which greatly facilitates the staff to read the value.

[0058] In this embodiment, the machine housing 1 has three chambers inside, namely a measuring tape chamber 13, a driving chamber 14, and a transmission chamber 15. A rectangular slot for the measuring tape to pass through is opened on the partition between the measuring tape chamber 13 and the transmission chamber 15.

[0059] Specifically, the measuring tape 7 is a steel measuring tape or a belt measuring tape. The whole measuring tape 7 is installed by the cooperation of a torsion spring and a movable shaft, and can be expanded under the drive of the transmission component 4. When moving in the reverse direction, with the cooperation of the torsion spring, the measuring tape can be wound up (due to the prior art, it will not be elaborated here).

[0060] In this embodiment, the transmission component 4 includes two slide bars 42. The two slide bars 42 are fixed inside the transmission chamber 15, and a lead screw 41 is arranged between the two slide bars 42. Both ends of the lead screw 41 are installed on the end walls at both ends of the transmission chamber 15 through bearings, and one end penetrates into the driving chamber 14 and is installed with a bevel gear 45 in cooperation. There are two bevel gears 45, and the other bevel gear 45 is installed on the output shaft of the driving motor 46, and the two bevel gears 45 are meshed at a 90-degree angle.

[0061] A slide block 44 for driving the sliding fabric clamping component 6 is threadedly connected to the lead screw 41, and both ends of the slide block 44 are slidably connected to the slide bars 42. A slide block 44 for clamping the measuring tape 7 is fixed on the top of the slide block 44.

[0062] Specifically, the driving motor 46 is electrically connected to the power supply module 8 and the controller 3. The controller 3 is also electrically connected to the power supply module 8.

[0063] By adopting the above technical solution, when working, the power supply module 8 provides power for the whole device. After turning on the controller 3, the driving motor 46 drives the screw rod 41 to rotate under the cooperation of two bevel gears 45. The sliding seat 44 converts the rotational motion of the screw rod 41 into a linear motion and slides along the slide bar 42. While driving the sliding fabric clamping component 6 to slide, the tape measure 7 is extended through the clamping seat 43 arranged at the top.

[0064] In this embodiment, the controller 3 is embedded in the top cover 2, and an observation window 10 is provided on the top cover 2 for facilitating the reading of the elongated length of the knitted fabric.

[0065] Further, the controller 3 can be, but is not limited to, a BLD-70 type controller.

[0066] The setting of the observation window 10 facilitates the reading of the scale after the knitted fabric is elongated.

[0067] In this embodiment, upper sliding grooves 11 and lower sliding grooves 12 for facilitating the sliding of the sliding fabric clamping component 6 are provided on the outer side of the machine shell 1, and a rectangular groove penetrates between the upper sliding groove 11 and the driving cavity 14.

[0068] The fixed fabric clamping component 5 and the sliding fabric clamping component 6 are composed of the same structure; among them, the fixed fabric clamping component 5 is fixed to the machine shell 1 by bolts; the sliding fabric clamping component 6 is fixedly connected to the sliding seat 44 through a connecting block;

[0069] Specifically, the sliding fabric clamping component 6 includes a first slider 61 slidably connected to the upper sliding groove 11. A top fixing handle 62 is fixed on the outer side of the first slider 61, and an arc-shaped clamping plate 63 is fitted and connected below the top fixing handle 62; the bottom of the arc-shaped clamping plate 63 is movably connected to an adjusting screw rod 64 through a bearing, and the other end of the adjusting screw rod 64 is threadedly connected to a wire drum 65.

[0070] By adopting the above technical solution, when fixing the knitted fabric, the fixing methods of the fixed fabric clamping component 5 and the sliding fabric clamping component 6 are the same; now, the fixing method of the knitted fabric by the sliding fabric clamping component 6 will be elaborated in detail:

[0071] Pull out one end of the knitted fabric and pass it through between the top fixing handle 62 and the arc-shaped clamping plate 63. Then rotate the adjusting screw rod 64, and use the cooperation degree of the adjusting screw rod 64 and the wire drum 65 to clamp and fix the knitted fabric between the top fixing handle 62 and the arc-shaped clamping plate 63;

[0072] When the sliding seat 44 slides, the first slider 61 and the second slider 69 can slide along the upper sliding groove 11 and the lower sliding groove 12.

[0073] Further, the lower end of the wire reel 65 is movably connected to the movable rod 66. The movable rod 66 is fixed inside the U-shaped seat 68, and a spring 67 is sleeved on the movable rod 66.

[0074] The inner side of the U-shaped seat 68 is fixedly connected to the second slider 69 that is slidably connected in the lower chute 12. The second slider 69 is also fixedly connected to the first slider 61 through a connecting plate.

[0075] By adopting the above technical solution, when clamping and fixing some knitted fabrics with smaller or too narrow widths, it is necessary to adjust the relative positions of the top fixing handle 62 and the arc-shaped clamping plate 63. The wire reel 65 can compress the spring 67 and slide outward. After sliding to a suitable position, directly rotate the adjusting screw rod 64 to tightly fix the top fixing handle 62 and the arc-shaped clamping plate 63.

[0076] In this embodiment, the power supply module 8 is fixed below one end of the machine shell 1, and a support 9 is provided below the other end of the machine shell 1.

[0077] The working principle of the present utility model is as follows: When in use, first fix one end of the knitted fabric to the fixed fabric clamping component 5, and the other end to the sliding fabric clamping component 6. When fixing, pull out one end of the knitted fabric and pass it through between the top fixing handle 62 and the arc-shaped clamping plate 63, and then rotate the adjusting screw rod 64. Utilize the cooperation degree between the adjusting screw rod 64 and the wire reel 65 to clamp and fix the knitted fabric between the top fixing handle 62 and the arc-shaped clamping plate 63.

[0078] After fixing, the power supply module 8 provides power for the entire device. After turning on the controller 3, the driving motor 46 drives the screw rod 41 to rotate under the cooperation of the two bevel gears 45. The sliding seat 44 converts the rotational motion of the screw rod 41 into a linear motion and slides along the sliding rod 42. When the sliding seat 44 slides, the first slider 61 and the second slider 69 can slide along the upper chute 11 and the lower chute 12 to achieve the elongation of the knitted fabric. While the knitted fabric is being stretched, the measuring tape 7 gradually unfolds. The length by which the knitted fabric is stretched is the same as the length by which the measuring tape 7 extends, which greatly facilitates the staff's reading.
