DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] At present, the osmosis membrane of the rolled water purification filter element is manufactured by the assembly line process. In the process, the membrane needs to be folded in half, and the folded position is the center seam of the membrane. In order to protect the membrane, it is necessary to stick tape on the center seam. The tape also needs to fix the coarse mesh to the membrane, so it is very important to stick tape. There is also equipment for sticking tape in the current process, which is to press the tape vertically to the center line of the membrane. When the tape is pressed down, the membrane and the coarse mesh need to stop and cannot move. Only after the tape is stuck can they move forward. This not only affects the production efficiency, but also requires adjustments to other processes, and the overall production process is not smooth.

[0019] Therefore, the present invention solves the technical problem that the membrane needs to be in a static state before the center seam tape can be attached during the existing permeable membrane production process, thereby improving production efficiency. Figure 1-4As shown, the following technical scheme is provided: an automatic tape-sticking device for a membrane of a roll-type water purification filter element, comprising a substrate 1, a linear guide 3 is horizontally arranged on the upper front side of the substrate 1, a tape gripper moving platform 4 is slidably arranged on the linear guide 3, a tape gripper assembly 7 is installed on the lower side of the tape gripper moving platform 4, the tape gripper moving platform 4 is driven by a translation drive assembly 12 to slide back and forth along the linear guide 3, a roller 9 is horizontally installed on the lower front side of the substrate 1, a tape adsorption strip 8 is axially installed on one side of the roller 9, vacuum adsorption holes are evenly distributed on the tape adsorption strip 8, the roller 9 is driven to rotate by a rotation drive assembly 10 installed on the substrate 1, and one end of the roller 9 is A tape cutting component 2 is installed on the side, a tape reel 5 is installed on the substrate 1 near the tape cutting component 2, a tape guiding component is arranged on the substrate 1 between the tape reel 5 and the tape cutting component 2, the tape guiding component guides the tape on the tape reel 5 to the position of the tape cutting component 2, the tape is grasped by the tape gripper component 7 and pulled flat to the other end of the roller 9, the tape cut by the tape cutting component 2 is adsorbed on the tape adsorption strip 8, and the tape is attached to the conveying membrane as the roller 9 rotates, the rotation of the roller 9 matches the moving rhythm of the tape gripper mobile platform 4, so that the tape can be continuously attached to the center position of the conveying membrane without stopping the production line, which greatly improves the production rhythm.

[0020] Specifically, the substrate 1 is a vertical plate-shaped structure and can be installed on a production line. The membrane and the coarse mesh both pass through the bottom of the drum 9, so the rotation of the drum 9 matches the transmission speed of the membrane and the coarse mesh. When the drum 9 drives the tape adsorption strip 8 to rotate to the bottom, it just corresponds to the center line position of the membrane, and the tape can be attached.

[0021] A side plate can be installed at one end of the base plate 1, and the translation drive assembly 12 and the rotation drive assembly 10 can both be installed on the side plate. At the same time, one end of the roller 9 can also be fixed by the side plate, and the other end of the roller 9 is fixed by a fixed bracket 6 installed on the base plate 1. A pad can be installed on the upper end of the fixed bracket 6, and a guide groove matching the width of the tape is provided on the upper end of the pad. After passing through the tape guide assembly, the tape passes horizontally from the guide groove. At the same time, a tape fixing pressing cylinder 11 is installed on the side of the tape cutting assembly 2 close to the tape reel 5 to press the end of the tape cut by the tape cutting assembly 2, so that each time the tape gripper assembly 7 can accurately grasp the end of the tape to ensure the continuous operation of the production line, the tape fixing pressing cylinder 11 can be installed on the upper side of the pad, and a pressure block is installed on the protruding rod of the tape fixing pressing cylinder 11. Pressing the end of the tape on the pad can keep the tape from moving.

The rotation of the roller 9 will not affect the normal use of the vacuum rotary air joint 22. A connecting pipeline can be set inside the roller 9 to connect the vacuum adsorption holes on the tape adsorption strip 8 with the vacuum rotary air joint 22.

A groove can be opened at the upper end of the tape adsorption strip 8 and the position of the tape cutter 14. When the tape cutter 14 cuts down, it just falls into the groove, so that the tape can be cut. The blade of the tape cutter 14 can be designed to be serrated.

Through the tape gripper upper and lower cylinders 71, the first gripper cylinder 72 and the second gripper cylinder The alternating use of 74 can realize the tape gripper 75 and the tape clamping wheel 76 to clamp, pull and release the end of the tape. Specifically, the upper and lower cylinders 71 of the tape gripper can drive the entire outer frame 73 and all components installed in the outer frame 73 to move up and down. When grabbing the tape and lowering the tape, the upper and lower cylinders 71 of the tape gripper will descend. When the tape needs to be grabbed, the first gripper cylinder 72 is extended and the second gripper cylinder 74 is also extended. When the end of the tape enters between the tape clamping wheel 76 and the tape gripper 75, the first gripper cylinder 72 retracts, so that the tape can be firmly clamped by the tape clamping wheel 76 and the tape gripper 75.

The tape coming out of the tape reel 5 can be first conducted downward, then conducted upward, and then enter between the tape cutting assembly 2 and the roller 9 in a horizontal state. The tape guide wheels 15 can be installed at the position where the tape needs to be turned, and the number can be adjusted as needed.

[0027] In this embodiment, a tape presence or absence detection sensor 21 is also installed at the position of the tape guide assembly. Once it is found that the tape being transmitted by the tape guide assembly is broken or used up, the production line can be stopped immediately.

[0028] As a specific implementation of the translation drive assembly 12, Figure 1 and 2 As shown, the translation drive assembly 12 includes a screw rod 127 parallel to the linear guide rail 3 and a screw rod slider 126 installed on the screw rod 127, the screw rod slider 126 is connected to the tape gripper moving platform 4, one end of the screw rod 127 is connected to the first driven wheel 124, one side of the first driven wheel 124 is provided with a first driving wheel 122, the first driven wheel 124 and the first driving wheel 122 are connected to each other through a first transmission belt 123, the first driving wheel 122 is driven by a first power motor 121, and one side of the first driven wheel 124 and the first driving wheel 122 is also provided with a first tensioning wheel 125 in contact with the first transmission belt 123, and the screw rod transmission enables the tape gripper moving platform 4 to move back and forth accurately.
