Description

Technical Field

[0001] The utility model relates to the technical field of tensioning devices, in particular to a cloth tension regulating mechanism. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, needle-punched cotton, etc., is composed of directional or random fibers. It is called cloth because it has the appearance and certain properties of cloth. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable. Non-woven fabric needs to be cut when used. The traditional cutting method is manual cutting. The advantage is that it can be cut into any shape. The disadvantage is that it is time-consuming, labor-intensive and inefficient. In normal industrial production, non-woven fabrics are often cut by non-woven fabric cutting machines to obtain a large number of non-woven fabrics of a certain shape.

[0003] When non-woven fabrics are fed, a tensioning mechanism is required to adjust the tension of the fabric, especially at the discharge end of the roll. The utility model with application number CN201922142595.5 discloses a fabric tension adjustment mechanism, which has a frame, on which a first motor and a second motor are rotatably mounted, the first motor is connected to a first guide roller by transmission, the second motor is connected to a second guide roller by transmission, and a plurality of driven guide rollers and a movable roller are arranged between the first guide roller and the second guide roller, the connecting end of the movable roller is placed in a movable groove on the frame, a servo motor is mounted on the frame, the servo motor drives the movable roller to move up and down, and the first motor, the second motor and the servo motor are connected to a programmable controller.

[0004] The utility model can adjust the tension of the fabric in actual use, but a driven guide roller needs to be set for guiding, which increases the setting length; in addition, when adjusting, the gear needs to be rotated to adjust the height of the movable roller, thereby adjusting the tension of the fabric, which is inconvenient to operate.

[0030] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-Figure 3 This embodiment discloses a cloth tension adjustment mechanism, including a first rotating shaft 101 and a second rotating shaft 102, both of which are connected to a support block 103, and both ends of the support block 103 connected to the first and second rotating shafts are connected by a support rod 104;

[0033] The first rotating shaft 101 and the second rotating shaft 102 are both connected to a bearing seat 105. The first and second rotating shafts are used to be installed on a frame 106 of the feeding equipment through the bearing seat 105.

[0034] A locking assembly 107 is provided between the first rotating shaft 101 and the frame 106. The locking assembly 107 includes a mounting plate 108, a ratchet 109 and a pawl 110. The ratchet 109 is mounted on the first rotating shaft 101. The mounting plate 108 is used to be mounted on the frame 106. The pawl 110 is rotatably mounted on the mounting plate 108 via a rotating shaft 111. A torsion spring is provided on the rotating shaft 111. Both ends of the torsion spring are respectively connected to the mounting plate 108 and the pawl 110. The ratchet 109 is mounted on the first rotating shaft 101 and cooperates with the pawl 110.

[0035] The present embodiment is mainly used for being installed on the frame 106 of the feeding equipment to adjust the tension of the cloth. In actual use, the cloth is pulled out from the roll and fed to the subsequent equipment. At this time, the first rotating shaft 101 and the second rotating shaft 102 need to be rotated so that the support rod 104 follows the rotation of the first rotating shaft 101 and the second rotating shaft 102 and contacts the cloth. Then the first rotating shaft 101 and the second rotating shaft 102 are rotated again so that the cloth is slightly lifted to adjust the tension of the cloth. When the tension is adjusted to a suitable tension, the first rotating shaft 101 and the second rotating shaft 102 are fixed after the ratchet 109 and the ratchet 110 are matched. If the tension needs to be adjusted again, it is only necessary to disengage the ratchet 109 and the ratchet 110 and rotate the first rotating shaft 101 and the second rotating shaft 102 again. The present invention can be directly installed on the frame 106 without increasing the length of the equipment. At the same time, the first rotating shaft 101 or the second rotating shaft 102 can be directly rotated during adjustment, which is more convenient to operate.

[0036] It should be noted that the cooperation between the pawl 110 and the ratchet 109 is mainly used to fix the first rotating shaft 101. In actual use, the first rotating shaft 101 can also be locked and fixed by means of locking screws to fix the first and second rotating shafts.

[0037] A rotating wheel 112 is disposed on the first rotating shaft 101 , so that it is more convenient to rotate the first rotating shaft 101 .

[0038] The support rod 104 is rotatably connected to the support block 103; a wear-resistant layer is provided on the outer side of the support rod 104. In actual use, the support rod 104 is connected to the support block 103 through a bearing. This allows the cloth to move more smoothly.

[0039] In some specific implementation cases, an adjustment unit 113 is arranged between the support rod 104 and the support block 103. The adjustment unit 113 includes a mounting seat 114, a screw 115 and a sliding assembly 116. The mounting seat 114 is installed on the support block 103 through the sliding assembly 116. The support rod 104 is rotatably installed on the mounting seat 114. The screw 115 is rotatably installed on the support block 103. After the screw 115 extends out of the support block 103, it is threadedly connected to a threaded hole provided on the mounting seat 114.

[0040] The position of the support rod 104 can be adjusted by the setting of the adjustment unit 113. When the height of the support rod 104 is higher, the tension of the fabric will be greater. The setting of the adjustment unit 113 can achieve fine adjustment of the tensioning force. By rotating the screw 115, the mounting seat 114 is moved, and then the support rod 104 is moved to achieve tension adjustment.

[0041] In actual use, the support rod 104 can be brought into contact with the cloth by adjusting the inclination angle of the support block 103, and then the cloth tension can be further adjusted by rotating the screw 115, so that different tensions can be adjusted as needed.

[0042] Furthermore, the sliding assembly 116 includes a first guide rod 117 and a second guide rod 118, and a guide hole 119 is provided on the support block 103. The first guide rod 117 and the second guide rod 118 are fixedly arranged on the support block 103, and the first and second guide rods are slidably matched with the guide hole 119. In this way, the mounting seat 114 can be more stable when moving.

[0043] The screw rod 115 is rotatably mounted on the support block 103 via a bearing, and the threads at both ends of the screw rod 115 have opposite rotation directions.

[0044] Furthermore, a first hand wheel 120 is provided on the screw rod 115, which makes adjustment more convenient.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
