DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A speed-adjustable tarpaulin heat sealing machine comprises a feeding platform 1, two mounting plates 3 are mounted on the feeding platform 1, heating components 14 are mounted on the two mounting plates 3, a cleaning belt 2 is arranged on the feeding platform 1 through two rotating rollers 13, a brush is arranged on the surface of the cleaning belt 2, feeding wheels 4 are arranged on the feeding platform 1 and the mounting plate 3, the two upper feeding wheels 4 are connected through a rotating shaft 7, and the upper and lower feeding wheels 4 are connected through a rotating mechanism, one end of the rotating roller 13 extends to one side of the feeding platform 1, one of the rotating rollers 13 is connected to the rotating shaft 7 through a transmission mechanism, a mounting frame 18 is arranged on the feeding platform 1 through a mounting groove 12, a plurality of extrusion grooves 15 are arranged on the mounting frame 18, a positioning block 16 is arranged in the extrusion groove 15 through an extrusion mechanism, a plurality of positioning holes are arranged on the bottom wall of the feeding platform 1, a speed regulating motor 8 is arranged on the mounting frame 18, and the speed regulating motor 8 is connected to the rotating shaft 7 through a plug-in mechanism.

[0022] The rotating mechanism includes a rotating pulley 5 installed on the feeding platform 1 and the rotating shaft 7 and connected to the feeding wheel 4. The two rotating pulleys 5 on the same side are connected by a rotating belt 6. The transmission mechanism includes a transmission pulley 10 installed on the rotating shaft 7 and the rotating roller 13. The two transmission pulleys 10 are connected by a transmission belt 11. With the help of the above components, after the speed regulating motor 8 is started, the feeding wheel 4 and the cleaning belt 2 can be rotated synchronously.

[0023] The extrusion mechanism includes a spring 17 arranged in the extrusion groove 15, and the two ends of the spring 17 are elastically connected to the inner wall of the extrusion groove 15 and the outer wall of the positioning block 16 respectively. The spring 17 realizes the extrusion operation of the positioning block 16, and can squeeze it into the positioning hole to achieve a stable connection of the mounting frame 18 relative to the feeding platform 1.

[0024] The plug-in mechanism includes a plug-in shaft 9 installed on the output shaft of the speed regulating motor 8, and a plug-in groove corresponding to the plug-in shaft 9 is provided on the end of the rotating shaft 7. The vertical cross-sectional views of the plug-in shaft 9 and the plug-in groove are both regular hexagons, which facilitates the synchronous rotation of the two after plugging together, and facilitates the two to disengage.

[0025] The mounting plate 3 is U-shaped, and the upper inner wall and the inner bottom wall of the mounting plate 3 are inclined. The inner bottom wall of the feeding platform 1 is also inclined. Figure 4As shown, the inner bottom wall of the mounting plate 3 is tilted downward from right to left, the upper inner wall of the mounting plate 3 is also tilted downward from right to left, and the inner bottom wall of the feeding platform 1 is tilted upward from right to left. The above-mentioned right side refers to one side of the cleaning belt 2, and the above-mentioned left side refers to the side away from the cleaning belt 2.

[0026] When the utility model is used, the two sides of the tarpaulin are U-shaped and enter the feeding platform 1 and the mounting plate 3. The tarpaulin is moved toward the left with the help of the feeding wheel 4. It is heated by the heating component 14 and moves toward the left. The U-shaped part of the tarpaulin will gradually approach and finally fit together, thereby completing the processing of the tarpaulin. In this process, the cleaning belt 2 rotates and cooperates with the brush to achieve the cleaning process of the tarpaulin, ensuring the cleanliness of the contact part, and its turning direction is opposite to the forward direction of the tarpaulin, ensuring the cleaning effect.

[0027] In this solution, the speed of the speed regulating motor 8 is adjustable (the model of the speed regulating motor 8 is: DR-3-10), and the contact time between the tarpaulin and the heating component 14 can be determined according to the material of the tarpaulin (tarpaulins of different materials have different melting points, thermal conductivity and other properties, so the heating time required to achieve a good heat sealing effect will also be different). The contact time can be achieved by adjusting the moving speed of the tarpaulin relative to the feeding platform 1.

[0028] In this solution, the positioning block 16 in the positioning hole on the bottom wall of the feeding platform 1 is pressed, and the positioning block 16 squeezes the spring 17 and then disengages from the positioning hole, thereby releasing the fixed installation of the mounting frame 18. The mounting frame 18 can be moved horizontally to drive the speed regulating motor 8 to complete the disassembly operation, making it easy to move to an open area or a maintenance platform for inspection and maintenance.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
