Figure 2 , Figure 3 The overall structure of the device provided in the embodiment of the present application is shown in FIG. Figure 3 , Figure 4 A schematic diagram of a partial structure of a seam tape storage box provided in an embodiment of the present application, Figure 5The schematic diagram of the cross-sectional structure at the third rotating drum provided in the embodiment of the present application. The pasting machine 100 applied to the seam tape includes a chassis 110, and the chassis 110 is used to install the remaining components, so the chassis 110 should have sufficient rigidity, and the chassis 110 can be made of a steel structure. The shape of the chassis 110 can be set according to the actual situation, and it only needs to meet the use requirements, and there is no restriction here. The bottom of the rear end of the chassis 110 is rotatably connected with a rolling wheel 111, and the rolling wheel 111 and the directional wheel 121 are jointly pressurized, and the rolling wheel 111 can tightly press the adhesive layer 210 separated and initially pasted on the road surface on the ground. The front end of the chassis 110 is connected to a mounting plate 120 through a rotating assembly 112, and the mounting plate 120 and the chassis 110 are connected through the rotating assembly 112, so the operator can rotate the mounting plate 120, the rotating armrest 130 and the directional wheel 121 by holding the rotating armrest 130, thereby changing the overall direction of travel of the equipment. The bottom of the mounting plate 120 is rotatably connected to a directional wheel 121, which is usually set as a double wheel. It is located at the front end of the equipment operation process and has the function of adjusting the overall direction of the equipment. At the same time, it and the rolling wheel 111 bear the weight together. The top of the mounting plate 120 is connected to a rotating handrail 130, which is for the operator to hold and implement direction control. The top of the chassis 110 is fixedly connected to a mounting support frame 113, which can be a steel frame. A seam tape storage box 140 is set on one side of the mounting support frame 113. A first rotating drum 145 is set in the seam tape storage box 140. After the seam tape is wound into a disk, it is connected to the first rotating drum 145. An opening 141 is set on one side of the seam tape storage box 140. After one end of the seam tape is led out along the opening 141 to the outside of the seam tape storage box 140, the adhesive layer 210 and the isolation film 220 can be separated. A second rotating drum 114 is fixed to the front end of the opening 141. The second rotating drum 114 is used to guide and support the adhesive layer 210. A recovery box 150 is provided between the mounting disk 120 and the rotating handle. The recovery box 150, the mounting disk 120 and the rotating handle can be provided as an integral structure. A recovery groove 151 is provided on the side of the recovery box 150 facing the opening 141. A third rotating drum 152 is rotatably provided in the recovery groove 151. The third rotating drum 152 is used to wind and roll up the isolation film 220. The third rotating drum 152 is coaxially connected to a driving device 153. The driving device 153 here is used to drive the third rotating drum 152 to rotate, thereby realizing the rolling up of the isolation film 220. The driving device 153 can be electric or manual. A drainage hole 115 is opened at the chassis 110, and a pressing cylinder 116 is arranged below the drainage hole 115. Both ends of the pressing cylinder 116 are rotatably connected to the chassis 110 through elastic members 160. After the adhesive layer 210 is separated from the isolation film 220 at the opening 141, the adhesive layer 210 is passed around the second rotating cylinder 114 so that it faces the ground and is attached.

[0030] In the embodiment of the present application, during operation, the rolled seam tape is placed on the first rotating drum 145 of the seam tape storage box 140, and then the head end of the seam tape is led out along the opening 141 to the outside of the seam tape storage box 140, and then the seam tape is layered. The isolation film 220 is stretched and fixed on the third rotating drum 152. During operation, the driving device 153 can roll the isolation film 220 onto the third rotating drum 152 while driving the third rotating drum 152 to rotate. The adhesive layer 210 is stretched and passed around the second rotating drum 114, and then stretched again and guided to the starting end of the ground crack and placed below the pressing drum 116. The operator can stand on the chassis 110 with one foot, hold the rotating armrest 130 with both hands to control the direction, and push the other leg back on the ground, relying on the reaction force to drive the equipment as a whole to move forward. During the movement, when the adhesive layer 210 passes through the pressing cylinder 116, the pressing cylinder 116 is abutted against the ground through the elastic member 160, and the adhesive layer 210 is located between the ground and the pressing cylinder 116. At this time, the adhesive layer 210 will be pressed down by the pressing cylinder 116 and thus adhere to the cracks in the ground. Subsequently, when the rolling wheel 111 passes by, since the rolling wheel 111 is the main load-bearing wheel, most of the operator's own weight and the overall weight of the equipment will act on the adhesive layer 210 through the rolling wheel 111, thereby pressing the adhesive layer 210 so that it can be tightly attached to the cracks in the road surface.

[0031] As can be seen from the above, in the embodiment of the present application, the seam tape storage box 140, the first rotating drum 145, the second rotating drum 114 and the third rotating drum 152 are provided to limit the seam tape, the adhesive layer 210 and the isolation film 220 respectively, so that the seam tape can be stably guided and limited after separation, the adhesive layer 210 can be adhered to the cracks in the ground, and the isolation film 220 can be rolled up, thereby realizing continuous operation. In the present application, the chassis 110, the rolling wheel 111, the directional wheel 121 and the covering cylinder 116 are arranged to cooperate with each other. On the one hand, since the covering cylinder 116 and the directional wheel 121 are located close to each other, and the adhesive layer 210 is positioned and initially adhered to the ground cracks by the covering cylinder 116, the operator can control the travel route of the equipment by observing the direction of the ground cracks and the relative position between the ground cracks and the directional wheel 121 after a short training, so as to achieve accurate adhesion. On the other hand, the rolling wheel 111 in the present application can both bear the weight and realize secondary rolling of the adhesive layer 210, so that the adhesive layer 210 can be tightly attached to the ground cracks by relying on the operator's own gravity and the equipment's gravity.

[0032] In some embodiments, the rotating armrest 130 includes at least one rotatable handle 131, the driving device 153 includes a first sprocket 153a coaxially connected to one end of the third rotating drum 152, a second sprocket 153b is coaxially connected to the handle 131, and a ring-shaped toothed chain 153c is meshed between the first sprocket 153a and the second sprocket 153b. In the present application, through the above-mentioned arrangement, the operator can conveniently rotate the handle 131 during the operation of the equipment, thereby further driving the second sprocket 153b through the handle 131, the second sprocket 153b drives the first sprocket 153a to rotate through the ring-shaped toothed chain 153c, and the first sprocket 153a further drives the third rotating drum 152 to rotate, so that the isolation membrane 220 can be tightened in time.

[0033] In some embodiments, the wheel diameter and the number of teeth of the second sprocket 153b are greater than the wheel diameter and the number of teeth of the first sprocket 153a. In the embodiment of the present application, through the above arrangement, when the handle 131 rotates one circle, the third drum 152 will rotate several circles, so as to facilitate the rapid winding of the isolation film 220 on the third drum 152. Specifically, the transmission ratio between the first sprocket 153a and the second sprocket 153b can be set and adjusted according to actual needs.

[0034] In some embodiments, the elastic member 160 includes a first mounting plate 161 rotatably connected to both ends of the pressure-coating cylinder 116, and a second mounting plate 162 corresponding to the first mounting plate 161 is provided at the chassis 110. The top of the first mounting plate 161 is penetrated by a limiting rod 163 and extends to the top of the second mounting plate 162, and a protrusion 163a is provided. The outer periphery of the limiting rod 163 is located between the first mounting plate 161 and the second mounting plate 162 and is sleeved with a compression spring 164. In the embodiment of the present application, through the above arrangement, when a steep slope appears on the road surface, the pressure-coating cylinder 116 located between the rolling wheel 111 and the directional wheel 121 will compress the compression spring 164 with the height of the road surface to achieve up and down fluctuations, ensuring that during the working process, the reaction force of the compression spring 164 on the pressure-coating cylinder 116 can compress the adhesive layer 210, so that the adhesive layer 210 is always close to the ground.

[0035] In some embodiments, a non-slip pedal 117 is provided on the top of the chassis 110 on one side of the mounting support frame 113, and an adjustable seat 113a is provided on the top of the mounting support frame 113. In the embodiment of the present application, through the above-mentioned setting, during the working process, the operator sits on the adjustable seat 113a, bends the right leg, places the foot on the non-slip pedal 117, and pushes the left leg backward to push the equipment. The adjustable seat 113a can achieve its height adjustability through various forms such as setting a lifting rod, and the setting of the above-mentioned adjustable seat 113a allows the operator to reduce physical energy consumption during the working process.

[0036] In some embodiments, the rotating assembly 112 includes a bent plate 112a fixed to the front end of the chassis 110, and the other end of the bent plate 112a is rotatably connected to the mounting plate 120 through a relatively large shaft 112b. For the convenience of description, the embodiment of the present application shows a specific setting method of the rotating assembly 112. During the working process, when the operator changes the direction by rotating the handrail 130, the bent plate 112a and the mounting plate 120 will rotate through the relatively large shaft 112b.

[0037] In some embodiments, a plurality of storage rods 118 are provided on the top of the chassis 110. In the embodiment of the present application, through the above arrangement, the spare seam tape can be sleeved on the storage rods 118, so as to facilitate the replacement and storage of the seam tape at any time.

[0038] In some embodiments, the rolling wheel 111 is connected to a motor, the motor is electrically connected to a battery and a control switch, and the control switch is arranged at the rotating armrest 130. In the embodiment of the present application, by arranging a motor (not shown in the figure), the rolling wheel 111 can be driven by the motor, thereby driving the whole device to move forward, further reducing the physical consumption of the operator and improving the working efficiency of the device.

[0039] In some embodiments, the storage box includes a box body 142 and a cover 143, the box body 142 and the cover 143 are hinged and tapped, and circular holes 144 are provided on opposite sides of the box body 142, and the circular holes 144 are surrounded by semicircular notches 152a provided on the cover 143 and the box body 142. The two ends of the first rotating drum 145 are rotatably connected to the two circular holes 144, and the opening 141 is surrounded by square holes provided on the cover 143 and the box body 142. In the embodiment of the present application, when the sealing tape needs to be replaced, the cover 143 is rotated to open the cover 143 and the box body 142, and then the first rotating drum 145 located in the semicircular notch 152a above the box body 142 is removed, and then a new sealing tape is replaced and connected to the first rotating drum 145, and the head end of the sealing tape is elongated and extended to the outside of the square hole, and finally the cover 143 is closed.

[0040] In some embodiments, a notch 152a is provided on the outer side of the third rotating drum 152, and a clamp 152b is provided at the notch 152a to fit in the notch 152a, and the clamp 152b is connected to the third rotating drum 152 through an elastic connector 152c. In the embodiment of the present application, through the above arrangement, after the replacement of the seam-seaming tape is completed, the isolation film 220 separated from the newly installed seam-seaming tape needs to be installed on the third rotating drum 152. At this time, a knife can be used to cut the isolation film 220 wound on the original third rotating drum 152, and then the clamp 152b is pushed. After the clamp 152b stretches the elastic connector 152c, a gap is formed between the notch 152a of the third rotating drum 152, and the head end of the new isolation film 220 is inserted into the above gap and the clamp 152b is released. At this time, the clamp 152b is reset under the action of the elastic connector 152c, and the isolation film 220 will be compressed.
