Description

Technical Field

[0001] The utility model relates to the field of cloth stretching machines, and more specifically, to a cloth pressing device of a cloth stretching machine. Background Art

[0002] A cloth spreading machine (also known as a cloth pulling machine) can lay rolled cloth flat on a machine table, and then use other machines to cut and reprocess the flat cloth. It is divided into manual and automatic types. The former has a simple structure, and the cloth is spread by manually pushing and pulling the machine back and forth. The latter is controlled by a computer. After the manual pulling machine pulls the cloth to a specified length, it is necessary to use a corresponding pressing block to press the end of the cloth to ensure the accuracy during cutting. This results in the need to manually pick up and then put down the pressing block every time the cloth is pulled, which is inefficient and prone to fatigue. Commonly used pressing blocks are metal blocks. If they slip out of your hands when you pick them up and put them down back and forth, they may fall to the ground, causing damage to the ground, equipment, and even personnel. Utility Model Content

[0021] Example:

[0022] See also Figure 1 and Figure 2 As shown, the cloth pressing device of the cloth stretching machine includes a cloth spreading platform 1, a support frame 2 is symmetrically arranged on one side of the top of the cloth spreading platform 1, cloth rolls 3 are arranged on the top of the two support frames 2, extension plates 5 are symmetrically arranged on both sides of the cloth spreading platform 1, a track rod 6 is fixed between the two extension plates 5 on the same side, and limited tooth grooves 61 are evenly arranged on the upper surface of the track rod 6. A moving box 7 is slidably installed on the surface of the track rod 6. The position of the moving box 7 is controlled to control the distance between the pressing plate 9 and the guide cutting mechanism 4, so as to flexibly adapt to the cutting of cloths of different lengths. The height of the moving box 7 exceeds the upper surface of the cloth spreading platform 1, and a rotating shaft 8 is installed between the two moving boxes 7 through a bearing. The rotating shaft 8 spans the cloth spreading platform. Above the table 1, a cavity 71 is opened inside the movable box 7, and pressure plates 9 are evenly arranged on the surface of the rotating shaft 8. Multiple pressure plates 9 are placed between the two movable boxes 7. Controlling the rotation of the rotating shaft 8 can realize the control of multiple pressure plates 9. The pressure plates 9 tilt downward when not subject to force. The pressure plates 9 are placed on the side close to the cloth roll 3. Bumps 10 are symmetrically arranged at both ends of the rotating shaft 8. The bumps 10 are placed inside the cavity 71. A tension spring 11 is connected to the side of the bump 10 close to the support frame 2, and the end of the tension spring 11 facing away from the bump 10 is connected to the inner wall of the cavity 71. When the rotating shaft 8 rotates to drive the pressure plate 9 to tilt up, the tension spring 11 can be pulled by the bump 10 to store force, so as to automatically press down and fix after the adjustment is completed.

[0023] Please refer to Figure 3 and Figure 4 As shown, one side of the rotating shaft 8 passes through the moving box 7, and a control slide rod 12 is slidably passed through the end of the rotating shaft 8. A control wheel 13 is provided at the end of the control slide rod 12. The control wheel 13 is placed on the outside of the rotating shaft 8. The external control wheel 13 is used to facilitate the effective control of the rotating shaft 8. A slide groove 16 is provided on the surface of the rotating shaft 8. A moving ring 15 is provided on the end of the control slide rod 12 away from the control wheel 13. The moving ring 15 is placed on the outside of the rotating shaft 8 and inside the cavity 71. Two connecting blocks are provided between the control slide rod 12 and the moving ring 15. The connecting blocks pass through the slide groove 16 so that the moving ring 15 can only move along the track of the slide groove 16.

[0024] Among them, a spring 14 is sleeved on the surface of the control slide rod 12, and the spring 14 is placed on the outside of the rotating shaft 8. One end of the spring 14 contacts the surface of the control wheel 13. The elastic force of the spring 14 makes the movable ring 15 closer to the control wheel 13 when not subject to external force. At this time, the bottom of the movable rod 19 cooperates with the limiting tooth groove 61 to achieve fixation. A boss 17 is arranged inside one side of the cavity 71, and the movable rod 19 is installed on the end of the boss 17 through a pin shaft. A U-shaped fork rod 18 is arranged on the top of the movable rod 19, and the U-shaped fork rod 18 is stuck on the outside of the movable ring 15. The cooperation between the two does not affect the rotation of the rotating shaft 8, so as to control the pressing piece 9. The top of the movable rod 19 is adapted to the internal size of the limiting tooth groove 61.

[0025] Please refer to Figure 1 A guide cutting mechanism 4 is provided on one side of the upper surface of the spreading platform 1 close to the support frame 2. The guide cutting mechanism 4 can use a cylinder to control the pressure strip to press the cloth, and a cutting tool is provided on the front side to cut the cloth.

[0026] Working principle: When in use, place the cloth roll 3 on the support frame 2, keep the cloth roll 3 in a suspended state, then pull the cloth through the guide cutting mechanism 4, adjust the distance between the moving box 7 and the guide cutting mechanism 4 according to the size of the cut cloth, and the control wheel 13 has an outward thrust due to the existence of the spring 14, so that the moving ring 15 is placed on the leftmost side of the formation, and the movable rod 19 is rotated by the U-shaped fork rod 18, so that the bottom of the movable rod 19 cooperates with the limiting tooth groove 61 to achieve fixation, and the control wheel 13 is pushed inward during adjustment to simultaneously drive the moving rings 15 on both sides to move in the direction away from the control wheel 13, so that the movable rod 19 The movable rod 19 rotates clockwise, so that the bottom of the movable rod 19 disengages from the limiting tooth groove 61, so that the position of the rotating shaft 8 can be moved at the same time. After the adjustment is completed, the squeezing of the control wheel 13 is released to make the internal mechanism return to its original position and re-match, so as to keep the cloth being pulled stably to the position of the rotating shaft 8. Rotating the control wheel 13 can drive the rotating shaft 8 to rotate, and then make the multiple pressing plates 9 on the surface tilt up, so that the end of the cloth can be placed on the lower side of the pressing plate 9. When the rotating shaft 8 is rotated, the tension spring 11 can be pulled by the protrusion 10 to store force. The control wheel 13 is released to use the stored force of the tension spring 11 to make the rotating shaft 8 return to its original position, and then the end of the cloth is pressed down and fixed by the pressing plate 9.
