Description

Technical Field

[0001] The utility model relates to the technical field of warp knitted fabric weighing equipment, and particularly relates to a warp knitted fabric falling and weighing device. Background Technique

[0002] The warp knitted fabric is a fabric knitted or woven through the warp knitting process, belonging to a textile process in the knitting field. It uses one or several groups of parallel arranged yarns to form loops simultaneously on all working needles fed into the machine in the warp direction to form a knitted fabric. This method is called warp knitting, and the formed knitted fabric is called a warp knitted fabric.

[0003] After production, the warp knitted fabric needs to be weighed. A warp knitted fabric falling and weighing mechanism is disclosed in Chinese Patent CN220508202U. In this device, the warp knitted fabric rolls from the feeding plate onto the panel, and the panel moves downward under the action of gravity to squeeze the sensing body, thereby realizing the weighing function. The setting of the transfer plate enables the warp knitted fabric to slide down in sequence;

[0004] Due to the lack of a positioning structure in the above patent, the warp knitted fabric roll cannot accurately stay at the center position of the panel. If the warp knitted fabric roll tilts towards one side of the panel, it will cause uneven stress on the panel. At this time, when the panel moves downward to squeeze the sensing body, due to the greater pressure between one side and the support, the friction is greater, thereby affecting the weighing effect and resulting in inaccurate weighing results.

[0005] Therefore, a warp knitted fabric falling and weighing device is proposed to solve the above-mentioned problems. Content of the Utility Model

[0006] Based on the above description, the utility model provides a warp knitted fabric falling and weighing device to solve the problem of inaccurate weighing results in the comparative patent.

The weighing sensor is arranged between the movable block and the bottom plate and is in contact with the lower surface of the stress block.

[0008] On the basis of the above technical solution, the utility model can be further improved as follows.

[0010] Furthermore, a guiding slide rail is provided at the bottom end of the main frame body. An opening is provided on the side of the vertical plate away from the sliding frame. The discharge port is communicated with the opening through the guiding slide rail.

[0011] Furthermore, the side cover includes a cover body. The cover body is arranged on both sides of the main frame body by screws. An installation groove is provided on the side of the cover body close to the roller groove, and a roller is arranged between the installation groove and the roller groove.

[0012] Furthermore, the bottom plate includes a plate body, and a convex block is provided at the top end of the plate body.

[0032] Please refer to Figure 1 、 Figure 5 and Figure 6 as shown, a warp knitting cloth-falling weighing device, comprising:

[0033] A conveying rack 1, which includes a main frame body 111, a sliding rack 112, a discharge port 114, a vertical plate 115, a guiding slide rail 116 and an opening 117;

[0034] A sliding rack 112, a discharge port 114 and a vertical plate 115 are arranged at the top of the main frame body 111. The discharge port 114 is arranged between the sliding rack 112 and the vertical plate 115. Roller grooves 113 are arranged on both side walls of the main frame body 111. Side covers 2 are arranged on both sides of the main frame body 111. A guiding slide rail 116 is arranged at the bottom of the main frame body 111. An opening 117 is arranged on the side of the vertical plate 115 away from the sliding rack 112. The discharge port 114 is communicated with the opening 117 through the guiding slide rail 116;

[0035] The side cover 2 includes a cover body 21. The cover body 21 is arranged on both sides of the main frame body 111 by screws. An installation groove 22 is arranged on the side of the cover body 21 close to the roller groove 113. A roller 3 is arranged between the installation groove 22 and the roller groove 113;

[0036] Based on the above, the warp knitted fabric roll can slide from the sliding rack 112 to the discharge port 114, and can slide along the direction of the guiding slide rail 116 towards the opening 117. Among them, the side cover 2 and the roller groove 113 cooperate with each other, so that rollers 3 can be arranged between the side cover 2 and the conveying rack 1. The arrangement of the rollers 3 makes the lateral movement of the weighing block smoother.

[0037] As Figure 1 shown, a hydraulic push rod 4 is arranged at the vertical plate 115;

[0038] Based on the above, the hydraulic push rod 4 plays the role of driving a weighing block, so that the distance between the two weighing blocks can be adjusted. On the one hand, the initial positions of the two weighing blocks can be adjusted, so that the device can weigh warp knitted fabric rolls with different diameters. On the other hand, after weighing, the distance between the two weighing blocks can be adjusted, so that the warp knitted fabric roll can fall from the discharge port 114.

[0039] As Figures 2 - 4 and Figure 7 shown, weighing blocks are respectively arranged at the top of the main frame body 111 and the output shaft of the hydraulic push rod 4, and include a movable block 5, a bottom plate 6, a stress block 7, a connecting frame 8, a ball 9, a connecting screw 10, a weighing sensor 11 and a support spring 12. Among them,

[0040] The movable block 5 and the stress block 7 are arranged at the top of the bottom plate 6 in sequence from bottom to top. The movable block 5 includes a block body 51. A movable hole 52 is arranged on the lower surface of the block body 51. The block body 51 is arranged at the top of the plate body 61 through a screw. The convex block 62 extends into the interior of the movable hole 52. The stress block 7 includes an isosceles right triangular prism 71. A hemispherical groove 72 is arranged on one side of the isosceles right triangular prism 71 close to the connecting frame 8. A connecting screw 10 is arranged at the bottom end of the isosceles right triangular prism 71. The connecting screw 10 is arranged in the movable hole 52. The diameter of the bottom of the connecting screw 10 is larger than the inner diameter of the top of the movable hole 52;

[0041] The bottom plate 6 includes a plate body 61, and a convex block 62 is arranged at the top of the plate body 61;

[0042] The connecting frame 8 includes a connecting frame body 81. The connecting frame body 81 is arranged between the stress block 7 and the movable block 5 through a screw. A through hole 82 is arranged on the surface of the connecting frame body 81. A ball 9 is arranged between the through hole 82 and the hemispherical groove 72. The ball 9 is in contact with the movable block 5;

[0043] The connecting screw 10 is arranged at the bottom end of the stress block 7 and extends into the interior of the movable block 5;

[0044] A support spring 12 is disposed between the connecting screw 10 and the bottom plate 6;

[0045] A weighing sensor 11 is disposed between the movable block 5 and the bottom plate 6 and is in contact with the lower surface of the force-receiving block 7;

[0046] Based on the above, the weighing block plays a role in weighing. Through the setting of the force-receiving block 7, when the warp knitting fabric roll slides between the two weighing blocks, the warp knitting fabric roll applies the same gravity to the two weighing blocks. Among them, the connecting screw 10 and the support spring 12 cooperate with each other to enable the force-receiving block 7 to move vertically, and after the movement, the weighing sensor 11 is squeezed. At this time, the weighing sensor 11 performs a weighing operation on the warp knitting fabric roll. When the weighing operation is completed, the force-receiving block 7 is reset under the upward elastic force of the support spring 12. The setting of the connecting frame 8 and the ball 9 enables the force-receiving block 7 to be sufficiently supported in the horizontal direction and enables the force-receiving block 7 not to get stuck or be affected by a large frictional force when moving vertically.

[0047] In actual use of this embodiment, through the setting of the hydraulic push rod 4, the distance between the weighing blocks can be adjusted, so as to ensure that the warp knitting fabric roll can be stuck between the two weighing blocks for weighing. Since the sizes of the two force-receiving blocks 7 on both sides are the same, when the warp knitting fabric roll is stuck between the two force-receiving blocks 7, the two force-receiving blocks 7 receive the same force, thereby ensuring uniform force during weighing of the device;

[0048] When the warp knitting fabric roll slides along the sliding rack 112 between the two weighing blocks, due to the action of gravity, the force-receiving block 7 moves downward. During this process, the connecting screw 10 moves downward to squeeze the support spring 12, causing the support spring 12 to generate a reverse elastic force while causing the weighing sensor 11 to be squeezed for weighing operation;

[0049] After weighing, when the hydraulic push rod 4 drives the weighing blocks to move, when the distance between the two weighing blocks is greater than the diameter of the warp knitting fabric roll, the warp knitting fabric roll drops from the discharge port 114 to the surface of the guiding slide rail 116 and slides along the guiding slide rail 116 and is discharged from the opening 117;

[0050] By changing the distance between the two weighing blocks, the device can not only achieve the function of discharging materials, but also can be adjusted according to the diameter of the warp knitting fabric roll to be weighed, so as to meet the effect that the device can weigh warp knitting fabric rolls with different diameters;

[0051] Compared with the comparative patent, the setting of the isosceles right triangular prism 71 makes the position where the warp knitting fabric roll stops constant, that is, between the two weighing blocks. Through the setting of the ball 6, the influence of the frictional force on the weighing result is minimized as much as possible, and the adjustable distance between the weighing blocks enables the warp knitting fabric roll not to be stuck and unable to be normally weighed.

[0052] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
