[0002] Sealing strips are products used to seal gaps between objects, and have the functions of internal and external sound insulation, heat insulation, water insulation, dustproof, fixation, and shock absorption. They are commonly used in various sealed containers, doors and windows, etc. Silicone foam sealing strips are soft and elastic, light and tough, highly heat-insulating and water-insulating, and have excellent impact resistance. They have good high and low temperature resistance, and are environmentally friendly and non-toxic. They can be used in a variety of fields and are a commonly used sealing strip choice.

[0003] Since direct cutting and forming is difficult and wasteful, sealing strips are usually produced by cutting them into single strips and then splicing them together. The sealing strip splicing device in the prior art is provided with a base for splicing. After the two sealing strips are glued and spliced ​​at the interface, they are placed in a groove of the base, and then a heating head is pressed from the top to heat and splice them.

DETAILED DESCRIPTION

[0027] Example 1

[0028] The following is a further explanation of the present invention in conjunction with specific embodiments. Figure 1 As shown, this embodiment is a device for the splicing process of sealing strips, especially silicone foam sealing strips, which mainly includes a base 1, a splicing structure is set on the base 1, and after the sealing strips are glued and spliced ​​through the splicing structure, as shown in FIG. Figure 2 As shown, after the top is hot-pressed at 150-180° C. by a heating block 8, the splicing of the sealing strip can be completed.

[0029] In this embodiment, a cross-shaped splicing rail 11 is provided on the base 1. The splicing rail 11 includes four rails, each of which is of equal length, and a sliding seat 2 is slidably connected in the rail; the sliding seat 2 can slide in the splicing rail 11, and a splicing seat 3 is provided on the sliding seat 2. Figure 3 As shown, a splicing groove is provided on the splicing seat 3, which can be used to place the sealing strip 5.

[0030] The splicing seat 3 includes a pair of symmetrically arranged splicing seats, namely a left splicing seat 31 and a right splicing seat 32; the left splicing seat 31 and the right splicing seat 32 are symmetrically arranged on the same sliding seat 2, and the difference between the two is that the left splicing seat 31 is provided with a protrusion at the outer end of the splicing groove, which is used to cooperate with the protrusion used for connection in the sealing strip 5; the left splicing seat 31 on each sliding seat 2 is provided with a protrusion, while the right splicing seat 32 is not provided, so it can be matched with the protrusions of the four sealing strips 5 respectively.

[0031] The left splicing seat 31 and the right splicing seat 32 cooperate with each other through the adjustment device set in the sliding seat 2, so that they can slide horizontally symmetrically synchronously; the structure of the adjustment device is as follows Figure 5As shown, it includes a pair of screw rods 23; the screw rods 23 are arranged inside the adjusting slide rail 27 through the fixing plate 25, and the screw rods 23 are rotatably connected to the fixing plate 25 so that the screw rods 23 can rotate around the axis; an adjusting shaft 28 is rotatably connected on the outer side of the sliding seat 2, and the adjusting shaft 28 passes through the side wall of the sliding seat 2 and extends into the adjusting slide rail 27, and one end of the outer side is connected to the adjusting turntable 21, and the inner end is connected to the two screw rods 23 respectively through a gear set 26.

[0032] The inner ends of the two screw rods 23 are fixedly connected to driven bevel gears. Figure 6 As shown, a driving bevel gear is fixedly connected to one end of the inner side of the adjusting shaft 28; the driving bevel gear is meshed with the two driven bevel gears at the same time, and is arranged between the two driven bevel gears. When the driving bevel gear rotates, the two driven bevel gears will rotate synchronously in opposite directions, and drive the two screw rods 23 to rotate synchronously in the opposite direction; Figure 4 As shown, threaded holes 33 cooperating with the screw rods are provided on the left splicing seat 31 and the right splicing seat 32. When the two screw rods 23 rotate in opposite directions, the left splicing seat 31 and the right splicing seat 32 will slide synchronously in opposite directions due to the restriction of the adjustment guide rail 27.

[0033] In this embodiment, the four sliding seats 2 are controlled by a synchronization device disposed in the splicing slide rail 11. When one of the sliding seats 2 slides, the other three sliding seats 2 will also slide synchronously. Figure 7 As shown, the synchronization device mainly includes a synchronization shaft 12 vertically arranged at the center position of the splicing slide rail 11; a pair of synchronization gears 13 are fixedly arranged on the synchronization shaft 12, and four racks 6 are arranged to cooperate with the two synchronization gears 13; the synchronization gears 13 and the synchronization shaft 12 are fixedly connected so that the three rotate synchronously.

[0034] The four racks 6 are fixedly connected to the four sliding seats 2 respectively. Figure 6 As shown, a slider portion 24 cooperating with the splicing slide rail 11 is provided at the bottom of the sliding seat 2, and two pairs of four rack mounting holes 29 are provided on the inner side of the slider portion 24; the rack mounting holes 29 are divided into two pairs, the upper and lower pairs, and the spacing of each pair is matched with a synchronous gear 13, so that the rack 6 installed therein can mesh with the synchronous gear 13; the rack 6 can be fixedly installed in the rack mounting hole 29, and the rack 6 can be fixed by means of buckles, pins, etc., and the length of the rack 6 extending out of the rack mounting hole 29 can be adjusted.

[0035] In this embodiment, the racks 6 of the pair of opposing sliding seats 2 are installed at the same position, that is, Figure 6The middle rack 6 is installed in the rack mounting hole 29 at the lower right corner, and the rack 6 on the opposite sliding seat 2 is also installed in the corresponding rack mounting hole 29 at the lower right corner; at this time, the opposite pair of racks 6 can be engaged with the synchronous gear 13 below from both sides at the same time. When one of the sliding seats 2 slides, the rack 6 slides accordingly, and the synchronous gear 13 engaged with it rotates at the same time, driving the other rack 6 to slide in the opposite direction, thereby driving the opposite sliding seat 2 to slide in the opposite direction synchronously.

[0036] The racks 6 of a pair of adjacent sliding seats 2 are installed in rack installation holes 29 at different heights on the same side, such as Figure 6 If the rack 6 is installed in the rack mounting hole 29 in the lower right corner, the adjacent sliding seat 2 needs to install the rack 6 in the rack mounting hole 29 in the upper right corner; this can prevent the racks 6 installed on adjacent sliding seats 2 from crossing and conflicting with each other; and when one sliding seat 2 is pushed, the rack 6 drives the synchronous gear 13 to rotate, and when the synchronous gear 13 rotates, it drives the synchronous rotating shaft 12 and another synchronous gear 13 to rotate together; when the other synchronous gear 13 rotates, it will drive the adjacent rack 6 meshing with it and set at different heights on the same side to slide, that is, it drives the adjacent sliding seat 2 to slide; and when the adjacent sliding seat 2 slides, it will also drive the other sliding seat 2 opposite to it to slide, so that by pushing one of the four sliding seats 2, the four sliding seats 2 can be driven to slide inward or outward synchronously.

[0037] When the present embodiment is actually used, firstly, according to the length of the sealing strip to be spliced, the spacing between the two splicing seats 3 is adjusted by rotating the adjusting dial 21 to change the length of the splicing groove; a scale line 22 is provided on the top surface of the sliding seat 2, which can be used to accurately control the length of the splicing groove; after adjusting the spacing between the splicing seats 3 on the four sliding seats 2 respectively, the sealing strips 5 coated with glue at the splicing position are respectively placed into the four splicing grooves; after placing the sealing strips 5, one of the sliding seats 2 is pushed inward, and the four sliding seats 2 slide inward synchronously, and when the adjacent splicing seats 3 are butted, the four sealing strips 5 can be butted neatly; then the top heating block 8 is pressed down, as shown in FIG. Figure 2 As shown, after hot pressing at 150-180° C., the splicing of the four sealing strips 5 is completed; in this embodiment, an anti-scalding film is provided at the splicing groove, which can play an anti-scalding role when removing the sealing strip 5 after hot pressing, and when placing the sealing strip 5 for continuous work, to avoid scalding the user.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that Figure 8As shown, an anti-scalding handle 7 is provided on the outer side of the sliding seat 2; the anti-scalding handle 7 can play a role in heat insulation and anti-scalding when the sliding seat 2 is pushed, and it is convenient to pull the sliding seat 2 back to its original position after completing one splicing.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 2 is that Fig. 9 As shown, this embodiment is a method of using the utility model when splicing a rectangular sealing strip 5 .

[0042] When the device suitable for the square sealing strip 5 is adjusted to be suitable for the rectangular shape, the length of the splicing groove needs to be changed according to the specific size so that the lengths of the adjacent long sides and short sides are different; after the splicing groove is adjusted, the upper synchronous gear 13 needs to be removed, and then each sliding seat 2 is manually pushed to the splicing state, such as Fig. 9 As shown, the upper synchronous gear 13 is installed in place; then the sliding seat 2 is pushed outward, and the rectangular sealing strip 5 can be spliced ​​as described in Example 1.
