Description

Technical Field

[0001] The present invention relates to the technical field of sound insulation strip processing, and more specifically, to a sound insulation strip processing device for door and window processing. Background Art

[0002] The demand for soundproof doors and windows is gradually increasing. Soundproof doors and windows use special materials and structural designs to effectively block the spread of external noise and improve the comfort of the indoor environment. The principle of sound insulation technology is mainly based on the sound absorption, sound insulation and reflection properties of the material. In soundproof doors and windows, sound insulation strips are key components, and their performance directly affects the sound insulation effect of doors and windows. At present, special cutting devices are required to cut the sound insulation strips during the processing of sound insulation strips.

[0003] The current sound insulation strip cutting device usually includes a workbench, a clamping block, a cutting device, a driving device and other structures. The sound insulation strip to be cut is released from the sound insulation strip reel, and the sound insulation strip is pulled onto the workbench and placed. The driving device drives the clamping block to clamp and limit the sound insulation strip, and the cutting device is used to cut the sound insulation strip at the appropriate position to cut the sound insulation strip into a suitable length.

[0004] Currently, during the cutting process, the sound insulation strip needs to be pulled out from the roll. The pulled out sound insulation strip may be in a twisted state. The twisted sound insulation strip is not convenient for subsequent cutting. The sound insulation strip needs to be straightened in time before cutting. Moreover, since the sound insulation strip has a large twisting force, when the twisting force is too large, the clamping block needs to be released to release the clamping block from clamping the sound insulation strip so that the sound insulation strip can be restored to a naturally straight state. However, the current sound insulation strip cutting equipment cannot automatically straighten and restore the sound insulation strip. After recovery, the sound insulation strip needs to be pulled back to the position of the clamping block to clamp and limit the sound insulation strip, resulting in the overall sound insulation strip cutting operation being more cumbersome.

[0044] Reference Fig. 9, two third L-shaped plates 60 are fixedly connected to the bottom of the connecting plate 5, the first toggle plate 31 and the second toggle plate 52 are respectively rotatably connected to the corresponding third L-shaped plates 60, the bottoms of the first toggle plate 31 and the second toggle plate 52 are in contact with the bottoms of the corresponding third L-shaped plates 60, and a seventh spring 61 is fixedly connected between the first toggle plate 31 and the second toggle plate 52 and the corresponding third L-shaped plates 60; when the electric push rod 4 drives the cutting device 6 and the connecting plate 5 to move downward, the connecting plate 5 drives the first toggle plate 31 through the third L-shaped plate 60. The movable plate 31 and the second toggle plate 52 move downward, and the first toggle plate 31 and the second toggle plate 52 contact the pull block 30 and the sliding plate 56 respectively. The first toggle plate 31 and the second toggle plate 52 rotate and pass over the pull block 30 and the sliding plate 56, and the seventh spring 61 is compressed and reset. During the upward reset process of the connecting plate 5, since the bottoms of the first toggle plate 31 and the second toggle plate 52 are in contact with the bottoms of the corresponding third L-shaped plate 60, the first toggle plate 31 and the second toggle plate 52 can pull the pull block 30 and the sliding plate 56 to move upward.

[0045] Working principle: When in use, pull the sound insulation strip to be cut from the reel, extend the sound insulation strip into the shell 2, straighten the sound insulation strip through the straightening component, straighten the sound insulation strip through the pad 7, the first limiting wheel 8 and the two first rotating wheels 14, and facilitate cutting. Start the cutting device 6 and the electric push rod 4, the electric push rod 4 drives the connecting plate 5 and the cutting device 6 to move downward, and the blade of the cutting device 6 enters the avoidance port to cut the sound insulation strip. After the cutting is completed, the sound insulation strip outside the shell 2 needs to be continuously transported into the shell 2, and the shell The sound insulation strip outside the housing 2 may be in a twisted state. It is necessary to first release the limit of the sound insulation strip by straightening the assembly through the release assembly. The sound insulation strip will automatically release the twisted state and return to a straight state, and then the sound insulation strip will be transported into the housing 2. During the recovery process of the sound insulation strip, the anti-detachment clamping assembly can clamp the sound insulation strip to prevent the sound insulation strip from escaping from the first limiting wheel 8 and the first rotating wheel 14 during the recovery process; the sound insulation strip to be cut is extended into the housing 2, and the bottom, top and two side walls of the sound insulation strip are respectively limited by the pad 7, the first limiting wheel 8 and the first rotating wheel 14. The first limiting wheel 8 and the first rotating wheel 14 prevent the sound insulation strip from entering the shell 2 in a distorted state, thereby realizing that the sound insulation strip entering the shell 2 is stopped. The purpose of straightening the sound insulation strips; in the process of conveying the sound insulation strips, the motor 21 is started, the motor 21 drives the third rotating shaft 22 to rotate, the third rotating shaft 22 drives another third rotating shaft 22 to rotate through two gears 23, the two third rotating shafts 22 drive the corresponding second rotating shafts 17 to rotate, the second rotating shaft 17 drives the other second rotating shafts 17 and the first rotating shaft 16 to rotate through the transmission wheel 24 and the transmission belt 25, so that the first rotating wheel 14 and the second rotating wheel 15 rotate, and the first rotating wheel 14 and the second rotating wheel 15 can convey the sound insulation strips to move;The electric push rod 4 can be started to drive the cutting device 6 to descend through the connecting plate 5 to cut the sound insulation strip. When the cutting device 6 is reset upward after cutting, the connecting plate 5 drives the pull block 30 to move upward through the first toggle plate 31. The pull block 30 pulls the third connecting rope 29. The third connecting rope 29 pulls the two third U-shaped plates 18 to move to both sides through the first connecting rope 26. The third U-shaped plate 18 drives the two first rotating wheels 14 to move to both sides so that the first rotating wheels 14 are not in contact with the sound insulation strip. The second spring 19 is compressed, and the third connecting rope 29 is connected to the second connecting rope 26. The connecting rope 28 can pull the first U-shaped plate 10 to move upward, and the first U-shaped plate 10 drives the first limiting wheel 8 to move upward, so that the first limiting wheel 8 is not in contact with the sound insulation strip, and the first spring 13 is compressed. When the first limiting wheel 8 and the first rotating wheel 14 are not in contact with the sound insulation strip at the same time, the twisted section of the sound insulation strip located outside the shell 2 will return to a straight state. When the first toggle plate 31 is not in contact with the pulling block 30, under the action of the first spring 13 and the second spring 19, the first limiting wheel 8 and the first rotating wheel 14 are in contact with the sound insulation strip again and limit it. During the movement of the rotating wheel 14, the first rotating wheel 14 will drive the first rotating shaft 16 and the transmission wheel 24 to move, thereby changing the position of the transmission belt 25. By setting the fixing column 62, the transmission belt 25 can be prevented from not contacting other transmission wheels 24. Since the transmission belt 25 is elastic, the first rotating wheel 14 can move and reset normally without affecting the subsequent work of the transmission wheel 24 and the transmission belt 25. During the resetting process of the cutting device 6 and the connecting plate 5, one end of the first toggle plate 31 contacts the pulling block 30, and the first toggle plate 31 can drive the pulling block The pull block 30 slides on the arc surface of the semicircular block 33, the pull block 30 slides in the two arc-shaped limit plates 35, and the third spring 37 is compressed. At this time, the pull block 30 can drive the first limit wheel 8 and the first rotating wheel 14 to not contact the sound insulation strip. When the pull block 30 is brought to a certain position, the first toggle plate 31 is not in contact with the pull block 30. Under the action of the third spring 37, the pull block 30 returns to the initial position, the first limit wheel 8 and the first rotating wheel 14 are also in contact with the sound insulation strip again, and the second guide wheel 34 can make the upper section of the third connecting rope 29 fit with the arc surface of the semicircular block 33;Before the first toggle plate 31 makes the first limiting wheel 8 and the first rotating wheel 14 not contact the sound insulation strip, the connecting plate 5 can pull the lifting plate 51 upwards through the second toggle plate 52, and the lifting plate 51 drives the two limiting blocks 40 to move toward the middle through the two connecting rods 50, and the fourth spring 42 is compressed. The two limiting blocks 40 are combined to form a circular opening, so that the two rollers 49 are in contact with the circular opening. Since the distance between the two rollers 49 is greater than the diameter of the circular opening, the circular opening can press the rollers 49 toward the middle, and the connecting block 46, the moving column 45 and the clamping block 48 move toward the middle, and the sound insulation strip is clamped by the clamping block 48. Clamping, when the first toggle plate 31 makes the first limiting wheel 8 and the first rotating wheel 14 not contact with the sound insulation strip, there is no limiting force to limit the sound insulation strip, the sound insulation strip will rotate and restore to a straight state, and the sound insulation strip will drive the annular plate 43 to rotate through the clamping block 48, so that the sound insulation strip will not be displaced in the axial direction, and the sound insulation strip is prevented from being separated from the first limiting wheel 8 and the first rotating wheel 14. By setting the sponge block 44, the surface of the sound insulation strip can be wiped and cleaned during the transportation process; in the process of resetting the connecting plate 5, compared with the contact between the first toggle plate 31 and the pulling block 30, the second toggle plate 52 will first contact with the sliding plate 56, and the second toggle plate 54 will first contact with the sliding plate 56, and the second toggle plate 54 will first contact with the sliding plate 56. The plate 52 can drive the sliding plate 56 to move upward, and the sliding plate 56 moves along the guide rod 57. The sliding plate 56 will gradually insert into the limiting groove 54. The sixth spring 55 is compressed, and the sliding plate 56 can drive the lifting plate 51 to move upward. The lifting plate 51 can make the two limiting blocks 40 move toward the middle to form a circular opening, and the sound insulation strip is clamped by the roller 49 and the clamping block 48. When the two limiting blocks 40 drive one end of the plug plate 59 to just enter the slot 58, the first toggle plate 31 can pull the pull block 30 to release the limit on the sound insulation strip, and the sound insulation strip can begin to restore the straight state. During the process of moving the pull block 30, the insert plate 59 is gradually inserted into the slot 58, and the sliding of the roller 49 in the circular opening is not affected during this process. After the first toggle plate 31 leaves the pull block 30, the sliding plate 56 gradually enters the limit groove 54 until the second toggle plate 52 is no longer in contact with the sliding plate 56. Under the action of the sixth spring 55, the sliding plate 56 is reset. Under the action of the fourth spring 42, the two limiting blocks 40 are reset, thereby releasing the clamping of the clamping block 48 on the sound insulation strip, so that the sound insulation strip can continue to be transported. The time when the first toggle plate 31 pulls the pull block 30 is fully covered by the time when the second toggle plate 52 pulls the sliding plate 56.When the electric push rod 4 drives the cutting device 6 and the connecting plate 5 to move downward, the connecting plate 5 drives the first toggle plate 31 and the second toggle plate 52 to move downward through the third L-shaped plate 60. The first toggle plate 31 and the second toggle plate 52 are in contact with the pull block 30 and the sliding plate 56 respectively. The first toggle plate 31 and the second toggle plate 52 rotate and pass over the pull block 30 and the sliding plate 56. The seventh spring 61 is compressed and reset. When the connecting plate 5 is reset upward, the bottoms of the first toggle plate 31 and the second toggle plate 52 are in contact with the bottoms of the corresponding third L-shaped plate 60, so that the first toggle plate 31 and the second toggle plate 52 can pull the pull block 30 and the sliding plate 56 to move upward. ;
