Description

Technical Field

[0001] This invention relates to the field of waterstop splicing technology, specifically to an auxiliary bonding device for adhesive rubber waterstops. Background Technology

[0002] In existing technologies, auxiliary bonding equipment for rubber waterstops is mainly used for bonding rubber waterstops using adhesive or hot-melt methods. This equipment typically includes a fixed frame, a base plate, a cover plate, and a hydraulic cylinder for applying pressure. During use, the cover plate is fastened to the base plate along a pre-fabricated position, and the hydraulic cylinder, housed within the frame, presses the cover plate down. Manually placing the hydraulic cylinder firmly presses the rubber waterstop joint between the base plate and the cover plate, as well as the raw material used for bonding, in the vertical direction. However, this method has some problems; existing auxiliary devices have shortcomings in actual operation. For example, manual placement of the hydraulic cylinder may lead to misalignment, uneven pressure on the cover plate, and pressing deviations, thus affecting the bonding quality of the rubber waterstops. Furthermore, most existing auxiliary devices can only provide vertical compressive force to the rubber waterstop, and their functionality is insufficient to address the issue of material displacement during the bonding process. Therefore, how to better solve this problem and improve the efficiency and accuracy of bonding equipment is an important direction for current technological development. Summary of the Invention

[0003] The present invention aims to solve the above problems, thereby providing an auxiliary bonding device for adhesive rubber waterstops.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: An auxiliary bonding device for adhesive rubber waterstops includes a fixed frame, a base plate located within the fixed frame, and a cover plate fastened to the top of the base plate. A pressure plate assembly is provided within the fixed frame and above the cover plate for pressing the cover plate. Grooves are formed on the opposing surfaces of the base plate and the cover plate. An extrusion seat that can move linearly in the horizontal direction is provided in the groove. Horizontal extrusion assemblies that control the movement of the extrusion seat are provided on the side walls at both ends of the base plate and the cover plate. The extrusion seat and the horizontal extrusion assembly are connected by a connecting block. The extrusion seat can move horizontally to the center under the drive of the horizontal extrusion assembly. Grooves adapted to the shape of the rubber waterstop are formed on the upper surfaces of both the base plate and the extrusion seat. The pressure plate assembly includes a horizontally placed pressure plate that is slidably connected to a fixed frame, allowing the pressure plate to slide up and down within the fixed frame. A pressure rod is rotatably connected to the center of the top surface of the pressure plate via a connecting seat. The top of the pressure rod extends upward through the fixed frame and has an external thread structure, which is threadedly connected to a threaded seat on the fixed frame. An insertion block is provided at the top of the pressure rod, with a horizontal insertion hole on the insertion block into which an insertion rod is inserted. Multiple extrusion columns are evenly distributed on the bottom surface of the pressure plate.

[0005] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: This invention, through the setting of the pressure plate assembly, can provide a multi-point contact effect on the cover plate, and the contact points are at the correct force angle relative to the cover plate. The operation process is simple, convenient and easy, and can effectively prevent the problems of pressing angle deviation and improper force position caused by the use of additional hydraulic cylinders in the prior art. At the same time, through the cooperation of the horizontal extrusion assembly and the extrusion seat, the automatic horizontal positioning and extrusion of the waterstop are effectively realized. This allows the material to be subjected to multi-angle pressure in both vertical and horizontal directions during the shaping and holding process, thereby maximizing the contact and bonding effect between materials and adhesives and significantly improving the bonding accuracy.

[0006] As a preferred embodiment, a further technical solution of the present invention is: There are four horizontal extrusion assemblies. Each horizontal extrusion assembly includes a force-bearing part and a limiting part. The four force-bearing parts are fixedly installed at both ends of the two side walls of the cover plate, and the four limiting parts are fixedly installed at both ends of the side walls of the bottom plate. The positions of the force-bearing parts and the limiting parts correspond to each other. The force-bearing parts act on both ends of an extrusion seat in pairs, pushing the two extrusion seats synchronously toward the center. The limiting parts limit the cover plate to prevent cross-movement during the extrusion process.

[0007] The force-bearing part includes a hollow fixing block, which is fixedly installed on the side wall of the cover plate. A limit strip is provided at the bottom center of the fixing block, and two drive strips are provided on both sides of the limit strip. The top of the drive strips extends upward into the inner cavity of the fixing block and connects with a lifting block provided in the inner cavity of the fixing block. Two drive columns are provided on the outer wall of the lifting block facing the extrusion seat. The drive columns are inserted into drive grooves opened on the connecting block connected to the end of the extrusion seat. The drive grooves are inclined, with the top inclined outward. Because the drive grooves are inclined, the vertical movement of the drive strips can be converted into the horizontal movement of the extrusion seat. The extrusion seat drives the rubber waterstop between the bottom plate and the cover plate to move towards the center position, thereby achieving a further horizontal material extrusion effect.

[0008] The limiting part includes a limiting block, which is fixedly installed on the side wall of the base plate. A limiting groove is provided in the middle of the limiting block to cooperate with the limiting strip; the limiting part limits the cover plate to prevent movement during the extrusion process.

[0009] The top edge of the limiting groove is arc-shaped, and its arc-shaped surface is the contact surface that abuts against the drive bar; this facilitates the entry of the limiting bar into the limiting groove.

[0010] Both ends of the cover plate have through holes in the middle. A small air pump and a pressure gauge are respectively installed at the bottom of the pressure plate above the two through holes. Air needles are installed below the small air pump and the pressure gauge. U-shaped air-blocking strips are installed on both sides of the top surface of the base plate, with the U-shaped openings of the two air-blocking strips facing each other. The installation of the small air pump and the pressure gauge can detect whether there are gaps at the joint position during the bonding and shaping process, and detect the reliability of the bonding material and position in advance.

[0012] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0013] See Figures 1-7An auxiliary bonding device for adhesive rubber waterstops includes a fixed frame 1, a base plate 2 located within the fixed frame 1, and a cover plate 3 fastened to the top of the base plate 2. A pressure plate assembly 4 is provided within the fixed frame 1 and above the cover plate 3 for pressing the cover plate 3. Grooves are formed on the opposing surfaces of the base plate 2 and the cover plate 3. An extrusion seat 13 that can move linearly in the horizontal direction is provided in the groove. Horizontal extrusion assemblies 6 that control the movement of the extrusion seat 13 are provided on the side walls at both ends of the base plate 2 and the cover plate 3. The extrusion seat 13 and the horizontal extrusion assembly 6 are connected by a connecting block 15. The extrusion seat 13 can move horizontally to the center under the drive of the horizontal extrusion assembly 6. Grooves adapted to the shape of the rubber waterstop are formed on the upper surfaces of both the base plate 2 and the extrusion seat 13. See Figure 2 The pressure plate assembly 4 includes a horizontally placed pressure plate 41, which is slidably connected to the fixed frame 1, allowing the pressure plate 41 to slide up and down within the fixed frame 1. A pressure rod 43 is rotatably connected to the center of the top surface of the pressure plate 41 via a connecting seat 42. The top end of the pressure rod 43 extends upward through the frame of the fixed frame 1. The pressure rod 43 has an external thread structure and is threadedly connected to a threaded seat 8 on the fixed frame 1. An insert block 44 is provided at the top end of the pressure rod 43. A horizontal insertion hole is opened on the insert block 44 and an insert rod 45 is inserted therein. Multiple extrusion columns 10 are evenly distributed on the bottom surface of the pressure plate 41.

[0014] See Figure 3-4 Four horizontal extrusion components 6 are provided. Each horizontal extrusion component 6 includes a force-receiving part 61 and a limiting part 62. The four force-receiving parts 61 are fixedly installed at both ends of the two side walls of the cover plate 3, and the four limiting parts 62 are fixedly installed at both ends of the side walls of the base plate 2. The positions of the force-receiving parts 61 and the limiting parts 62 are corresponding. The force-receiving parts 61 act on both ends of an extrusion seat 13 in pairs. When the cover plate 3 is pressed down, the two extrusion seats 13 are pushed towards the center at the same time. The limiting parts 62 limit the cover plate 3 to prevent cross-movement during the extrusion process.

[0015] See Figure 5-7The force-bearing part 61 includes a hollow fixing block 611, which is fixedly mounted on the side wall of the cover plate 3. A limit strip 612 is provided at the bottom center of the fixing block 611. Two drive strips 613 are provided on both sides of the limit strip 612. The top of the drive strip 613 extends upward into the inner cavity of the fixing block 611 and is connected to a lifting block 614 provided in the inner cavity of the fixing block 611. Two drive columns 615 are provided on the outer wall of the lifting block 614 facing the extrusion seat 13. The drive columns 615 are inserted into the extrusion seat 13. The drive groove 616 on the connecting block 15 at the end is inclined with the top tilted outward; the fixed block 611 has an inclined opening on the side wall near the extrusion seat 13 to accommodate the movement of the drive column 615. Since the drive groove 616 is inclined, the vertical movement of the drive bar 615 can be converted into the horizontal movement of the extrusion seat 13. The extrusion seat 13 drives the rubber waterstop between the bottom plate 2 and the cover plate 3 to move towards the center position, thereby achieving a further horizontal material extrusion effect.

[0016] The limiting part 62 includes a limiting block 621, which is fixedly installed on the side wall of the base plate 2. A limiting groove 622 is provided in the middle of the limiting block 621 to cooperate with the limiting strip 612; the limiting part limits the cover plate 3 to prevent movement during the extrusion process.

[0017] The top edge of the limiting groove 622 is arc-shaped, and its arc-shaped surface is the contact surface 623 that abuts against the drive bar 613; this facilitates the entry of the limiting bar 612 into the limiting groove 622.

[0018] Both ends of the cover plate 3 have through holes 9 in the middle. A small air pump 5 and a pressure gauge 11 are respectively installed at the bottom of the pressure plate 41 and above the two through holes 9. Air needles 12 are respectively installed below the small air pump 5 and the pressure gauge 11. U-shaped air blocking strips 14 are installed on both sides of the top surface of the bottom plate 2, and the U-shaped openings of the two air blocking strips 14 are opposite each other. The installation of the small air pump 5 and the pressure gauge 11 can detect whether there are gaps at the joint position during the bonding and shaping process, and detect the reliability of the bonding material and position as early as possible.

[0019] The fixed frame 1 is equipped with reinforcing ribs 7 to increase the overall strength of the fixed frame.

[0020] When using this invention, the rubber waterstops on both sides are placed flat, then the end faces are ground, and adhesive rubber strips or rubber strips are applied and placed in the adhesive gap. Then, the device is used to press and wait for the adhesive to solidify.

[0021] After the air needle at the end of the small air pump is inserted into the inflation area on the left, the inflation area will be pressurized. Due to poor adhesion or the presence of gaps, the airflow will pass through the unsecured position, penetrate the waterstop strip, and reach the pressure gauge sensing area on the right. If the pressure gauge displays a reading or the pointer shakes, it indicates that the current waterstop strip is not waterproof and requires further treatment or re-adhesion.

[0022] This invention, through the setting of the pressure plate assembly, can provide a multi-point contact effect on the cover plate, and the contact points are at the correct force angle relative to the cover plate. The operation process is simple, convenient and easy, and can effectively prevent the problems of pressing angle deviation and improper force position caused by the use of additional hydraulic cylinders in the prior art. At the same time, through the cooperation of the horizontal extrusion assembly and the extrusion seat, the automatic horizontal positioning and extrusion of the waterstop are effectively realized. This allows the material to be subjected to multi-angle pressure in both vertical and horizontal directions during the shaping and holding process, thereby maximizing the contact and bonding effect between materials and adhesives and significantly improving the bonding accuracy.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
