Problems solved by technology

However, the existing strap-type mask machines only set two groups of separation mechanisms, and the length of the ear straps is controlled by controlling the distance of the separation mechanisms. When the inner ear straps are wrinkled, the length of the ear straps will be very large The deviation does not meet the relevant product standards and affects the quality of the product

Embodiment 1

[0029] In this example, if figure 1 As shown, the present invention is used for welding and fixed-distance separation of the ear straps of the strap-type mask. Specifically, the present invention is installed between the feed line 3 and the discharge line 4, and the feed line 3 is used to provide The mask sheet body of the earband, the mask sheet body is covered with upper earbands on both sides in the feeding mechanism 2, and the welding is completed in the traction mechanism 5, and then the fixed distance separation of the earbands is realized by the separation mechanism 6, and the separated belts The mouth mask sheet body that ear band is arranged enters next process by discharge line 4.

[0030] In this example, if Figure 1~3 As shown, a mechanical fixed-distance separation device includes a mounting base 1, a feeding mechanism 2, a traction mechanism 5, a separation mechanism 6 and a controller 7. Two vertical plates 11 are arranged on the mounting base 1, and the tract...

Embodiment 2

[0042] This embodiment provides an optional solution for the specific structure of the separation mechanism 6 on the basis of the first embodiment.

[0043] In this example, if image 3 As shown, both sides of the outlet end of the traction mechanism 5 are equipped with a separation mechanism 6. The separation mechanism 6 includes a cutting drive mechanism 61 and a cutter 62. The middle part of the cutter 62 is rotatably mounted on the mounting seat 1 through a connecting piece 63. One end of the cutter 62 It is connected with the cutting drive mechanism 61 , the other end of the cutter 62 is the cutting end, and the connecting piece 63 is located at both ends of the discharge port of the traction mechanism 5 .

[0044] In this embodiment, specifically, the cutting driving mechanism 61 is an air cylinder, and several support frames are arranged at the bottom of the installation base 1 , the air cylinder is installed on the support frames, and the movable shaft of the air cylin...

Embodiment 3

[0048] This embodiment provides an optional solution for the specific structure of the feeding mechanism 2 on the basis of any of the above embodiments.

[0049] In this example, if figure 1 As shown, the feeding mechanism 2 includes a feeding tray 21 and a material guide rail 22. The center of the feeding tray 21 is provided with a rotating shaft, and the material is sleeved on the rotating shaft. Turn and rotate the discharging, and the guide rail 22 is used to guide the material.

[0050] In this embodiment, specifically, the material guide rail 22 gradually narrows from one end of the tray 21 to one end of the third traction roller 53, and the material is an ear belt, and the ear belt enters the material guide rail 22 before the ear belt It is a wide single-layer ear strap. As the material guide rail 22 gradually narrows, the ear strap that enters the traction mechanism 5 is folded into a double-layer ear strap, and the mask sheet enters the double-layer ear strap from th...

Abstract

The invention discloses a mechanical fixed-distance separation device, and relates to the field of non-standard automation equipment. The mechanical fixed-distance separation device comprises a mounting seat, a feeding mechanism, a traction mechanism, a separation mechanism and a controller, the traction mechanism draws materials through a first traction roller, a second traction roller and a third traction roller, the conditions of wrinkles and the like in the ear belt traction process can be effectively prevented, the advancing distance of an ear belt can be well determined by controlling the number of rotation turns of traction rollers, then the traction mechanism and the separation mechanism are controlled through the controller, when the first traction roller of the traction mechanism rotates by a certain number of turns, the separation mechanism conducts cutting once, the length of the ear belt completely depends on the number of rotation turns of the traction mechanism, the number of rotation turns of the traction roller is completely controllable, so that the accuracy is higher, and the length of the ear belt is more accurately controlled.

Description

technical field [0001] The invention belongs to the field of non-standard automation equipment, and in particular relates to a separation device with mechanical fixed distance. Background technique [0002] A mask is a kind of hygiene product, which generally refers to wearing on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper and other materials. [0003] Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Masks can be divided into air filter masks and air supply masks. [0004] The mask machine is a multi-layer non-woven fabric through hot pressing, folding forming, ultrasonic welding, waste removal, ear strap nose bridge welding and other processes to produce various masks with certain filte...
