Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0028] First embodiment:

[0029] Figure 1 The figure shows a left side structural schematic diagram of the rubber sealing strip bonding device according to the first embodiment of the present utility model. Figure 2 The figure shows the main structural diagram of the pressing block and the clamping block of the first embodiment of the present invention. Figure 1 and Figure 2 As shown, the utility model discloses a rubber sealing strip bonding device.

[0030] The rubber sealing strip bonding device includes: a pressing block 1 respectively arranged at both ends of the cross-section of the rubber sealing strip, a clamping block 2 arranged on the pressing block 1, a hot mold heating system 3 for heating the cross-section of the rubber sealing strip, and a hot mold temperature control system 4 for detecting the temperature of the pressing block 1.

[0031] The heating end of the hot mold heating system 3 and the temperature measuring end of the hot mold temperature control system 4 are installed within the compression block 1. The clamping block 2 is installed horizontally above the compression block 1. The cross-section of the rubber sealing strip is placed within the compression block 1, and the clamping block 2 compresses the cross-section of the rubber sealing strip within the compression block 1. When the compression blocks 1 are connected, the cross-sections of the rubber sealing strips align with each other.

[0032] The hot mold heating system 3 heats the compression block 1, raising the temperature of the rubber seal section, melting the adhesive applied there, and completing the bonding. The hot mold temperature control system 4 monitors the temperature of the compression block 1 to prevent it from being overheated and affecting the bonding process.

[0033] The pressing block 1 is formed with a space 11 to accommodate the cross-section of the rubber sealing strip. The pressing block 1 is opened toward the clamping block 2.

[0034] An opening is formed at the upper end of the space 11. The cross-section of the rubber sealing strip is placed into the space 11 from above. The inner surface of the space 11 fits the cross-section of the rubber sealing strip, completing the accommodation restriction of the cross-section of the rubber sealing strip.

[0035] The clamping block 2 is secured to the compression block 1 via a first fixing member 21. For example, the first fixing member 21 is a bolt. The first fixing member 21 is threaded into the clamping block 2 and the compression block 1 from top to bottom. After tightening the first fixing member 21, the clamping block 2 presses down on the upper end of the rubber sealing strip section, securely clamping the section within the space 11.

[0036] The compression blocks 1 are connected to each other via a second fixing member 12. Exemplarily, the second fixing member 12 is a bolt. The second fixing member 12 is screwed into one compression block 1 in a forward-backward direction, and then into the other compression block 1, completing the connection between the two compression blocks 1. Turning the second fixing member 12 causes the compression blocks 1 to move the two ends of the rubber sealing strip's cross-section closer together, bringing them into contact and facilitating bonding.

[0037] The hot mold heating system 3 includes a heating pipe 31 and a heating controller 32. The heating pipe 31 is arranged in the compression block 1 near the rubber sealing strip. The heating controller 32 is electrically connected to the heating pipe 31.

[0038] The hot mold temperature control system 4 includes a temperature sensor 41 and a temperature controller 42. The temperature sensor 41 is disposed in the compression block 1. The temperature sensor 41 and the heating controller 32 are electrically connected to the temperature controller 42.

[0039] In this application, electrical connection can be understood as a form of connection between different components in a circuit structure through physical circuits such as PCB copper foil or wires that can transmit electrical signals.

[0040] After the rubber sealing strip bonding device brings the cross-sections of the rubber sealing strips into contact with each other, it is necessary to heat the compression block 1 to a temperature of 110-130°C, then maintain the temperature for 20 minutes. After that, the heating is stopped and the temperature of the compression block 1 is lowered to 40°C. The first and second fixing members 21 and 12 are unscrewed, and the compression block 1 and clamping block 2 are removed. The cross-sections of the rubber sealing strips are now bonded.

[0041] The temperature controller 42 transmits a signal to the heating controller 32 according to the temperature detected by the temperature sensor 41 , and the heating controller 32 controls the heating tube 31 to complete the opening and closing, heating and heat preservation actions.

[0042] Second embodiment:

[0043] Figure 3 A schematic diagram of the main structure of the pressing block and the clamping block in the second embodiment of the present utility model is shown. Figure 4 The left side structural diagram of the bottom plate and the reference plate of the second embodiment of the present invention is shown. Figure 1-Figure 4 As shown,

[0044] The compression blocks 1 are provided with latches 13. For example, there are two sets of latches 13. Latches 13 are located on the side of one compression block 1 that is adjacent to the other. When the compression blocks 1 are connected, one compression block 1 gradually approaches the other, and the latches 13 are inserted into the adjacent compression block 1. The latches 13 act as guides, ensuring accurate connection between the compression blocks 1 and preventing positional deviation.

[0045] The rubber sealing strip bonding device also includes a reference plate 5. The reference plate 5 is horizontally disposed. A groove 51 is formed in the upper surface of the reference plate 5 in a horizontal direction. The lower end of the pressure block 1 forms a base plate 14. When the pressure block 1 is slidably mounted on the reference plate 5, the base plate 14 is positioned within the groove 51 and slides horizontally.

[0046] Slide the clamping block 1 over the cross-section of the rubber sealing strip so that the cross-section of the rubber sealing strip is inside the clamping block 1, and then clamp it with the clamping block 2. The clamping block 1 and the clamping block 2 may be offset during clamping, and the clamping block 1 may not be accurately connected. The clamping block 1 and the clamping block 2 may need to be clamped multiple times to achieve accurate clamping.

[0047] In the second embodiment, the pressing blocks 1 are placed on the reference plate 5, and the positions of the pressing blocks 1 are accurate. Then, the cross-section of the rubber sealing strip is placed in the pressing blocks 1 and clamped and fixed by the clamping blocks 2. The connection between the pressing blocks 1 is accurate and convenient to operate.

[0048] First inclined surfaces 15 are formed on both sides of the bottom plate 14. Second inclined surfaces 52 are formed on both sides of the groove 51. The first inclined surfaces 15 and the second inclined surfaces 52 are fitted together to increase the contact area between the bottom plate 14 and the reference plate 5, so that the pressing block 1 can slide smoothly.

[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
