It is necessary to expand the groove of the connecting joint to facilitate the insertion of a polyethylene rod, then apply silicone sealant, and finally cover it with a waterproof cloth to achieve the effect of waterproof treatment.

[0003] However, the current treatment of connecting joints of exterior walls of prefabricated panel buildings mainly has the following problems: 1. When installing a polyethylene rod in a connecting joint, it is often done manually with one hand holding the polyethylene rod and the other hand pressing the polyethylene rod into the expanded groove of the connecting joint. Since this operation needs to be carried out at a high place, the occupation of both hands affects the safety during the processing operation and also affects the installation efficiency.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0032] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0033] See also Figure 1 , Figure 2 and Figure 3 A device for processing joint seams of exterior wall of assembled board building comprises a shell 10; rollers 11 are evenly arranged on the right end surface of the shell 10, a feeding mechanism 2 is arranged at the lower part of the inner cavity of the shell 10, a pressing mechanism 3 is arranged above the feeding mechanism 2, a square hole 12 is opened on the right side of the upper part of the shell 10, and the pressing mechanism 3 is installed in the square hole 12, and a limiting mechanism 4 is arranged at the right end of the lower part of the shell 10.

[0034] See also Figure 1 , Figure 2 and Figure 4, the limiting mechanism 4 includes square grooves 40. On the lower right side of the housing 10, two square grooves 40 are symmetrically arranged front and back. A bidirectional screw 41 is jointly hinged in the two square grooves 40. The two spiral sections of the bidirectional screw 41 are respectively located in the two square grooves 40. A shaft seat 42 is slidably connected in the square groove 40, and the shaft seat 42 is connected to the bidirectional screw 41. A ball 43 is installed on the opposite side of each of the two shaft seats 42.

[0035] During specific operation, manually fit the roller 11 against the wall surface, and then rotate the bidirectional screw 41 to move the two shaft seats 42 away from each other, so that the balls 43 move against the inner wall of the widened groove on the connecting seam between the ball 43 and the exterior wall of the prefabricated building, thereby realizing the limitation of the moving direction of the present invention and enabling the polyethylene rod to be accurately pressed into the widened groove.

[0036] Refer to Figure 3 , the feeding mechanism 2 includes a U-shaped plate 20. The U-shaped plate 20 is slidably connected to the lower part of the inner cavity of the housing 10. A push-pull rod 21 is hinged to the left vertical section of the U-shaped plate 20. One side of the push-pull rod 21 away from the U-shaped plate 20 is hinged with a cam 22, and the cam 22 is rotationally connected to the housing 10 through a pin shaft 25. A limiting groove 23 is opened in the corresponding part of the inner cavity of the housing 10 and the right vertical section of the U-shaped plate 20. A clamping unit 5 is slidably connected in the limiting groove 23. A fixing unit 6 is arranged above the clamping unit 5, and a reset member 24 is arranged in the limiting groove 23 above the fixing unit 6.

[0037] During specific operation, first fit the roller 11 against the wall and limit the movement of the housing 10 through the limiting mechanism 4. Then, an existing motor drives the pin shaft 25 to rotate, the pin shaft 25 drives the cam 22 to rotate, and the cam 22 drives the U-shaped plate 20 to reciprocate up and down through the push-pull rod 21. During the upward movement of the U-shaped plate 20, it will contact the fixing unit 6, so that the clamping unit 5 first clamps the polyethylene rod and then moves upward for feeding, and then the polyethylene rod is pressed into the widened groove of the connecting seam of the exterior wall of the prefabricated building through the pressing mechanism 3. When the U-shaped plate 20 moves downward, the fixing unit 6 first moves away from the polyethylene rod through the reset member 24 and then moves downward to reset.

[0038] Refer to Figure 3 and Figure 5 , the clamping unit 5 includes an L-shaped block 50. The L-shaped block 50 is slidably connected in the limiting groove 23, and a slot hole 51 is opened in the vertical section of the L-shaped block 50. The right vertical section of the U-shaped plate 20 is slidably matched with the slot hole 51. A T-shaped rod 52 is arranged at the end of the U-shaped plate 20 in the slot hole 51, and the T-shaped rod 52 sequentially passes through the L-shaped block 50 and the fixing unit 6. A push rod 53 is slidably connected to the horizontal section of the L-shaped block 50. A driving member 7 is arranged between the push rod 53 and the T-shaped rod 52, and an extrusion member 8 is arranged on the side of the push rod 53 away from the L-shaped block 50.

[0039] Refer to Figure 5 The driving member 7 includes a through groove 70. The T-shaped rod 52 is provided with the through groove 70. One end of a connecting rod 71 is hinged to the inner wall of the through groove 70. A square opening is formed in one side of the push rod 53 close to the T-shaped rod 52. The other end of the connecting rod 71 away from the T-shaped rod 52 is hinged to the inner wall of the square opening of the push rod 53.

[0040] During specific operation, when the cam 22 rotates to pull the U-shaped plate 20 upward through the push-pull rod 21, the T-shaped rod 52 moves upward along with the U-shaped plate 20. At the same time, the T-shaped rod 52 will push the push rod 53 to move towards the pressing member 8 through the connecting rod 71, so as to drive the pressing member 8 to clamp and fix the polyethylene rod. Then, the fixing unit 6 is driven, so that the polyethylene rod can be fixed by the clamping unit 5 first and then moved upward for feeding.

[0041] Refer to Figure 5 and Figure 6 The pressing member 8 includes a fixing plate 80. One fixing plate 80 is respectively arranged at the front and rear ends of the horizontal section of the L-shaped block 50, and the fixing plate 80 is in an L-shaped structure. A driving plate 81 connected to the push rod 53 is slidably connected between the two fixing plates 80, and the driving plate 81 is in a U-shaped structure. Two contact plates 82 are installed at the ends of the two horizontal sections of the driving plate 81. A through hole is formed in the middle of the contact plate 82. The two sides of the opposite surfaces of the two contact plates 82 are inclined surfaces. An extrusion plate 83 is installed between the contact plate 82 and the fixing plate 80 through a spring column, and an inclined convex surface in contact with the inclined surface of the driving plate 81 is arranged on one side of the extrusion plate 83 close to the driving plate 81.

[0042] Refer to Figure 3 and Figure 7 The reset member 24 includes a notch 240. The notch 240 is formed in the inner part of the limiting groove 23 away from the limiting block 60. A stopper 241 is slidably installed in the notch 240 through a compression spring, and the end face of one side of the stopper 241 away from the compression spring is in an isosceles triangle structure.

[0043] During specific operation, when the push rod 53 pushes towards the pressing member 8, the driving plate 81 moves towards the contact plate 82, and at the same time, the two contact plates 82 are pushed. The contact plates 82 push the extrusion plates 83 to approach each other to clamp the polyethylene rod. Then, the fixing unit 6 is driven. The polyethylene rod will move upward with the U-shaped plate 20 for feeding. At this time, the fixing unit 6 moves above the stopper 241. During the process of the U-shaped plate 20 moving downward, when the fixing unit 6 contacts the stopper 241, the push rod 53 will move downward first to make the extrusion plate 83 away from the polyethylene rod, and then the fixing unit 6 and the clamping unit 5 move downward to reset.

[0044] Refer to Figure 3 、 Figure 5 and Figure 8The fixing unit 6 includes a limit block 60, a limit block 60 is arranged above the L-shaped block 50, and the limit block 60 is slidably matched with the limit groove 23, a through hole 61 is opened in the middle of the limit block 60, and a fixing rod 62 is symmetrically arranged on the inner wall of the through hole 61, and the fixing rod 62 is inserted into the shell 10, and the fixing rod 62 is slidably connected to the limit block 60 through a compression spring, and an inclined groove 63 is opened on the side of the fixing rod 62 close to the axis of the through hole 61, and an inclined block 64 matching the inclined groove 63 is arranged on the push rod 53 between the L-shaped block 50 and the fixing rod 62.

[0045] During specific operation, the T-shaped rod 52 moves upward and pushes the push rod 53 first, so that the extrusion piece 8 clamps the polyethylene rod, and then the T-shaped rod 52 moves upward, the inclined block 64 is inserted into the inclined groove 63, and the fixed rod 62 is pulled toward the T-shaped rod 52, so that the fixed rod 62 is separated from the shell 10, so that the U-shaped plate 20 can drive the polyethylene rod to move upward for feeding through the feeding mechanism 2. At this time, the limit block 60 moves to the top of the stop block 241. When the feeding mechanism 2 moves downward and resets, the limit block 60 will be blocked by the stop block 241, so that the inclined block 64 moves out of the inclined groove 63, thereby keeping the fixed unit 6 away from the polyethylene rod. At the same time, the fixed rod 62 contacts the shell 10 under the action of the compression spring. At this time, the horizontal section of the T-shaped rod 52 contacts the limit block 60, so that the limit block 60 can be pulled, so that the limit block 60 moves downward and pushes the stop block 241 into the slot 240, so that the feeding mechanism 2 can first loosen the polyethylene rod and then move downward and reset.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Fig. 9 The pressing mechanism 3 includes a fixed block 30, and the fixed block 30 is installed on the upper part of the inner cavity of the shell 10. A V-shaped rod 31 is installed on the right side of the fixed block 30. The other end of the V-shaped rod 31 is hinged to a limiting wheel 32, and the cross-section of the limiting wheel 32 is an H-shaped structure. A connecting rod 33 is hinged to the right end face of the fixed block 30 away from the limiting wheel 32, and a supporting rod 34 is hinged to the side of the connecting rod 33 away from the fixed block 30. A pressing wheel 35 is hinged at one end of the support rod 34 away from the connecting rod 33, and an adjusting member 9 is provided on the side of the connecting rod 33 away from the limiting wheel 32, and the limiting wheel 32 and the pressing wheel 35 extend to the outside of the shell 10 through the square hole 12.

[0047] During specific operation, when the feeding mechanism 2 pulls the polyethylene rod upward, the shell 10 is manually moved downward, and the limiting wheel 32 rolls on the expansion groove of the connecting seam, thereby pre-pressing the polyethylene rod into the expansion groove of the connecting seam. At the same time, the pressure presses the polyethylene rod pre-pressed into the expansion groove into place to ensure the subsequent waterproof effect. The adjusting rod can control the extension and retraction amount of the pressing wheel 35 to the outside of the shell 10 to ensure the installation quality of the polyethylene rods in the expansion grooves of connecting seams of different depths.

[0048] See also Fig. 9 The adjusting member 9 includes a threaded rod 90, and a threaded rod 90 is arranged on the upper part of the shell 10. The threaded rod 90 is rotatably connected to a support plate 91 on the side close to the fixed block 30. The support plate 91 is hinged to the connecting rod 33 on the side away from the screw rod, and the support plate 91 is slidably connected to the connecting rod 33. A waist groove is opened on the support rod 34, and a slider 92 is slidably connected in the waist groove. A push spring 93 is arranged between the slider 92 and the upper inner cavity of the shell 10.

[0049] During specific operation, the threaded rod 90 is manually rotated, and the threaded rod 90 will move to the outside of the shell 10. At the same time, the connecting rod 33 is pulled upward to rotate through the support rod 34, and the pressure wheel 35 is first extended to the outside through the support rod 34 to ensure the installation quality of the polyethylene rod in the expansion groove of the deeper connecting seam. At the same time, the push spring 93 will keep the support rod 34 pushed downward, thereby increasing the pressure of the pressure wheel 35 on the polyethylene rod.

[0050] When the present invention is used to process the joint seams of the exterior walls of assembled board buildings, the polyethylene rod is first manually inserted into the shell 10, and then the upper end of the polyethylene rod is fixed in the expanded groove of the joint seams of the exterior walls of the assembled board buildings. The roller 11 is then fitted to the wall surface, and the limiting mechanism 4 is fitted to the inner wall of the expanded groove of the joint to limit the movement of the shell 10. Then, the clamping unit 5 is first clamped by the fixing unit 6 and then moved upward to feed the material. During the feeding process, the shell 10 is manually pushed downward, and the pressing mechanism 3 at this time presses the polyethylene rod pulled by the feeding mechanism 2 into the expanded groove of the joint.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
