Description

Technical Field

[0001] This invention belongs to the field of fabric splicing machine technology, specifically, it relates to a fabric splicing machine and a splicing processing method. Background Technology

[0002] The tarpaulin splicing machine is a specialized piece of equipment used for splicing, sealing, and binding the widths of thermoplastic coated tarpaulins, knife-coated tarpaulins, and plastic-coated fabrics such as PVC, PE, and EVA. It seamlessly welds two pieces of tarpaulin together by heating and melting and then cooling under pressure, forming a high-strength, waterproof, and airtight weld that completely replaces traditional glue or sewing.

[0003] Tarpaulin splicing machines are divided into handheld hot air splicing machines, automatic walking hot air splicing machines, and high-frequency tarpaulin machines. Among them, the handheld hot air splicing machine is more widely used. When using it, the staff places two tarpaulins on a table, then places the splicing machine on the tarpaulins. The staff pushes the splicing machine back and forth to continuously heat-melt the splicing surfaces of the two tarpaulins.

[0004] However, since the bottom of the splicing machine is supported by the moving wheels, when the operator manually pushes the splicing machine on the table, the machine's path is easily deviated due to uneven force applied by the hand or insufficient guidance. This can cause the tarpaulin seams to misalign, directly affecting the splicing accuracy and quality. Summary of the Invention

[0005] The purpose of this invention is to provide a tarpaulin splicing machine and a splicing processing method, which solves the technical problem in related technologies that the splicing machine is prone to deviation when the operator moves the splicing machine by hand.

[0006] At least one embodiment of the present invention provides a tarpaulin splicing machine, including a splicing machine body, a guide frame, a guide rail, a lateral fixing component, and a horizontal adjustment and pressing component. Two guide frames are provided, each mounted on the side of the splicing machine body via two telescopic mounting components. Two guide rails are provided, each with a guide frame slidably mounted on one of the guide rails. The guide rails limit the movement of the guide frames, allowing the splicing machine body to move vertically back and forth. The lateral fixing components are provided on both sides of each guide frame, configured to securely place the guide frame on a table when it is placed on the table. Two horizontal adjustment and pressing components are provided, each positioned between the two guide rails, configured to both adjust the distance between the two guide rails equidistantly and press down the tarpaulin on the table.

[0007] In order to enable the guide frame to be installed on the side of the splicing machine body and to be adjusted synchronously with the guide rail, the installation telescopic assembly further includes a mounting cover and a telescopic cover. The mounting cover is fixedly installed on the side of the splicing machine body, and the telescopic cover is detachably installed inside the mounting cover by bolts. The guide frame is slidably installed on the side of the telescopic cover.

[0008] To ensure the guide rail is fixed when placed on a table, the lateral fixing assembly includes an adjusting plate, an adjusting frame, a friction plate, and a horizontal adjusting assembly. The adjusting plate is fixedly installed on the side of the guide rail, the adjusting frame is slidably installed on the side of the adjusting plate, the friction plate is fixedly installed at the bottom of the adjusting frame, and the horizontal adjusting assembly is disposed on the adjusting plate. The horizontal adjusting assembly includes a reciprocating screw, a slider, a moving frame, and a handwheel. The reciprocating screw is rotatably installed on the top of the adjusting plate via a mounting plate, the slider is installed on the reciprocating screw, one end of the moving frame is fixedly installed on the side of the slider, and the handwheel is coaxially fixedly installed on the reciprocating screw. A groove is provided at the top of the adjusting plate, and a sliding rod is slidably installed in the groove. The bottom end of the slider is fixedly connected to the top end of the sliding rod. A through groove is provided on the side of the adjusting plate, and the other end of the moving frame passes through the through groove and is fixedly connected to the side of the adjusting frame.

[0009] When adjusting the two guide rails for tarpaulins of different widths, the horizontal adjustment and pressing assembly further includes an adjusting rod, a pressing plate, and a limiting and fixing assembly. An adjusting rod is fixedly installed on the side of each guide rail. The pressing plate is positioned between the two adjusting rods, and the other ends of the two pressing plates are slidably installed on both sides of the adjusting rods. The limiting and fixing assembly is located on the pressing plate and includes a limiting frame and limiting posts. The limiting frame is fixedly installed on the top of the pressing plate, and two limiting posts are provided. The two limiting posts are respectively installed on both sides of the limiting frame via connecting ropes. Limiting holes are provided at the top of both the limiting frame and the pressing plate, and a limiting groove is provided at the top of the adjusting rod. The limiting posts are adapted to the limiting holes and the limiting grooves.

[0010] A method for processing fabric webs using a fabric web-splitting machine, comprising the following steps: Step 1: Equipment Installation: When splicing tarpaulins, first place two tarpaulins to be spliced ​​on the table. Then, install the telescopic cover inside the mounting cover with bolts. Next, slide the guide frame into the telescopic cover. Then, place the two guide frames horizontally on the table and press down the non-splicing parts of the tarpaulins. Then, the worker holds the splicing machine body and places it on the table. At this time, the bottom ends of the two guide frames are inserted into the guide grooves of the two guide rails respectively. Step 2, Adjusting the Spacing: Adjust the distance between the two guide frames according to the length of the tarpaulin to make it easier for the splicing machine to move. During adjustment, the operator first moves one of the guide frames to the side. The guide frame drives the side adjustment rod to move outward in the lower pressure plate. After moving to the appropriate position, stop. At this time, the limiting groove of the adjustment rod is aligned with one of the limiting holes of the limiting frame and the lower pressure plate. Then, the limiting post is inserted into the limiting hole and the limiting groove to fix the adjustment rod. At the same time, the other guide frame moves to the same position and distance, and the lower pressure plate presses down on the tarpaulin to fix it. Step 3: Stabilize the guide frame: The staff then turns the handwheel, which drives the reciprocating screw to rotate, thereby causing the slider to move the adjustment frame back and forth within the adjustment plate, and in turn, to move the friction plate until the friction plate is in contact with the side of the table, thus fixing the guide frame. Step 4: Splicing the tarpaulin: After all the installation is completed, the staff starts the splicing machine and pushes it to splice the tarpaulin at the connection points.

[0011] The tarpaulin splicing machine provided in this embodiment of the invention, through the cooperation between the guide frame, guide rail, lateral fixing component and horizontal adjustment and pressing component, can limit the left and right movement of the splicing machine body when the operator pushes the splicing machine body to move and splice at the joint of the tarpaulin, so that it can only move back and forth, thereby avoiding the problem of the splicing machine body shifting due to manual pushing by the operator. When splicing tarpaulins, the movement of the guide frame on the guide rail can limit the left and right movement of the splicing machine body. The guide rail and the lower pressure plate can press down on the tarpaulin, so that the tarpaulin can be placed stably on the table. When the splicing machine body moves on the tarpaulin, it can also prevent the tarpaulin from wrinkling or shifting. In addition, the guide frame can be fixedly installed on the table by the lateral fixing component, thereby reinforcing the placement of the guide rail on the table. This not only presses down the tarpaulin, but also prevents the splicing machine body from driving the guide rail to shift synchronously when guiding and limiting the splicing machine body.

[0023] Example 1 illustrates a tarpaulin splicing machine according to an embodiment of the present invention, such as... Figure 1As shown, the machine includes a web-splitting machine body 1, a guide frame 2, a guide rail 3, a lateral fixing component, and a horizontal adjustment and pressing component. There are two guide frames 2, which are respectively mounted on the side of the web-splitting machine body 1 via two telescopic mounting components. There are two guide rails 3, which are respectively slidably mounted on the two guide frames 2. The guide rails 3 limit the movement of the web-splitting machine body 1 vertically back and forth. Each guide frame 2 has a lateral fixing component on both sides, which is configured to securely place the guide frame 2 on the table. There are two horizontal adjustment and pressing components, which are both located between the two guide rails 3 and are configured to both adjust the distance between the two guide rails 3 at equal intervals and press down the tarpaulin on the table.

[0024] When splicing the tarpaulin, place it on a table, such as... Figure 2 As shown, the two guide frames 2 are then installed on both sides of the splicing machine body 1 by installing the telescopic assembly. The telescopic assembly includes a mounting cover 4 and a telescopic cover 5. The mounting cover 4 is fixedly installed on the side of the splicing machine body 1, and the telescopic cover 5 is detachably installed inside the mounting cover 4 by bolts. The guide frame 2 is slidably installed on the side of the telescopic cover 5. Specifically, the operator inserts the side of the telescopic cover 5 into the mounting cover 4, and then fixes the telescopic cover 5 and the mounting cover 4 together by bolts. Then the guide frame 2 is slid into the side of the telescopic cover 5.

[0025] After installing the guide frame 2 on the side of the splicing machine body 1, place the two guide rails 3 on the table, and then adjust the two guide rails 3 according to the width of the tarpaulin using the horizontal adjustment and pressing component, such as... Figure 4 and Figure 6 As shown, the horizontal adjustment and pressing assembly includes an adjusting rod 13, a pressing plate 14, and a limiting and fixing assembly. An adjusting rod 13 is fixedly installed on the side of each guide rail 3. The pressing plate 14 is located between two adjusting rods 13, and the other ends of the two pressing plates 14 are slidably installed on both sides of the adjusting rods 13. The limiting and fixing assembly is located on the pressing plate 14. The limiting and fixing assembly includes a limiting frame 15 and a limiting post 16. The limiting frame 15 is fixedly installed on the top of the pressing plate 14. There are two limiting posts 16, and the two limiting posts 16 are respectively installed on both sides of the limiting frame 15 through connecting ropes.

[0026] Specifically, if the width of the tarpaulin is short, it can push the two guide rails 3 to move relative to each other. The two guide rails 3 then drive the side adjusting rods 13 to move, thereby moving the adjusting rods 13 within the lower pressure plate 14. At this time, the lower pressure plate 14 can be placed on the tarpaulin. It should be noted that the lower pressure plate 14 presses down on the width of the tarpaulin because the top of both the limiting frame 15 and the lower pressure plate 14 has limiting holes, and the top of the adjusting rod 13 has a limiting groove. The limiting post 16 is adapted to the limiting holes and limiting grooves, thus moving one of the guide rails 3 to the appropriate position. When the position is correct, the limiting groove of the adjusting rod 13 is aligned with the limiting hole of the limiting post 16 and the limiting groove of the lower pressure plate 14. Then, the limiting post 16 is inserted into the limiting hole and the limiting groove to fix the adjusting rod 13. Simultaneously, the guide rail 3 on the other side moves to the same distance. It should be noted that the limiting holes and limiting grooves of the limiting frame 15 and the lower pressure plate 14 are symmetrical with respect to the central axis. The distance between the number of limiting holes and limiting grooves on both sides is consistent. Therefore, the distance that the guide rail 3 on one side moves can be measured by aligning the limiting holes and limiting grooves.

[0027] After the distance was adjusted, both guide rails 3 and the lower pressure plate 14 pressed down on the tarpaulin, as... Figure 3 and Figure 5 As shown, the two guide rails 3 are then stably placed using a lateral fixing assembly. The lateral fixing assembly includes an adjusting plate 6, an adjusting frame 7, a friction plate 8, and a horizontal adjusting assembly. The adjusting plate 6 is fixedly installed on the side of the guide rail 3, the adjusting frame 7 is slidably installed on the side of the adjusting plate 6, the friction plate 8 is fixedly installed at the bottom of the adjusting frame 7, and the horizontal adjusting assembly is set on the adjusting plate 6. The horizontal adjusting assembly includes a reciprocating screw 9, a slider 10, a moving frame 11, and a handwheel 12. The reciprocating screw 9 is rotatably installed on the top of the adjusting plate 6 via a mounting plate, the slider 10 is installed on the reciprocating screw 9, one end of the moving frame 11 is fixedly installed on the side of the slider 10, and the handwheel 12 is coaxially fixedly installed on the reciprocating screw 9.

[0028] Specifically, during the fixing process, the operator rotates the handwheel 12, causing the reciprocating screw 9 to rotate at the top of the adjusting plate 6. Subsequently, the slider 10 moves on the reciprocating screw 9. Because the top of the adjusting plate 6 has a groove, a slide rod 17 is slidably installed in the groove. The bottom end of the slider 10 is fixedly connected to the top end of the slide rod 17, so the slider 10 can move back and forth on the reciprocating screw 9. Furthermore, the side of the adjusting plate 6 has a through groove, and the other end of the moving frame 11 passes through the through groove and is fixedly connected to the side of the adjusting frame 7. Thus, the slider 10 can drive the moving frame 11 to move back and forth, and the moving frame 11 in turn drives the adjusting frame 7 and the friction plate 8 to move back and forth, so that the side of the friction plate 8 is in contact with the side of the table. Because the friction force is greater after the side of the friction plate 8 is in contact with the table, the guide rail 3 can be placed stably on the table.

[0029] The staff then held the splicing machine body 1 and placed it on the tarpaulin on the table. At this time, the bottom ends of the two guide frames 2 were inserted into the two guide rails 3 and could slide. When the staff pushed the splicing machine body 1 to move, the guide frames 2 could slide in the guide rails 3 in sync, thereby limiting the left and right movement of the splicing machine body 1.

[0030] Working principle: When splicing the tarpaulin, first place the tarpaulin on the table. Then, the staff inserts the side of the telescopic cover 5 into the mounting cover 4. Then, the telescopic cover 5 and the mounting cover 4 are fixed together with bolts. Then, the guide frame 2 is slid into the side of the telescopic cover 5. After the guide frame 2 is installed on the side of the splicing machine body 1, the two guide rails 3 are placed on the table.

[0031] After placement, adjust the two guide rails 3 according to the width of the tarpaulin. During adjustment, if the tarpaulin is short, the two guide rails 3 can be pushed to move relative to each other. The two guide rails 3 will then drive the side adjustment rods 13 to move, thereby moving the adjustment rods 13 within the lower pressure plate 14. At this time, the lower pressure plate 14 can be placed on the tarpaulin. When one of the guide rails 3 is moved to the appropriate position, the limiting groove of the adjustment rod 13 is aligned with the limiting hole of the limiting post 16 and the limiting groove of the lower pressure plate 14. Then, the limiting post 16 is inserted into the limiting hole and the limiting groove to fix the adjustment rod 13. Simultaneously, the other guide rail 3 moves to the same distance. If the tarpaulin is long, it can be stretched outward.

[0032] After adjustment, the operator turns the handwheel 12, which drives the reciprocating screw 9 to rotate at the top of the adjustment plate 6. Then the slider 10 moves on the reciprocating screw 9. The slider 10 can move back and forth on the reciprocating screw 9, and the slider 10 can drive the moving frame 11 to move back and forth. The moving frame 11 then drives the adjustment frame 7 and the friction plate 8 to move back and forth, so that the side of the friction plate 8 fits against the side of the table, and the guide rail 3 is placed stably on the table.

[0033] Finally, the staff member holds the splicing machine body 1 and places it on the tarpaulin on the table. At this time, the bottom ends of the two guide frames 2 are inserted into the two guide rails 3 respectively and can slide with the splicing machine body 1. When the guide frame 2 is moved down into the guide rail 3, the telescopic cover 5 can be pulled. Thus, when adjusting the position of the guide rail 3, the guide frame 2 is moved above the guide rail 3 by pulling the telescopic cover 5.

[0034] At this time, the hot air nozzle and pressure roller of the splicing machine body 1 are aligned with the overlap seam of the two tarpaulins. Then, the splicing machine body 1 is started, and the hot air system starts to work, heating the overlap seam of the tarpaulin to melt and soften the thermoplastic coating on the surface of the tarpaulin. At the same time, the pressure roller applies pressure to the molten area, making the two layers of tarpaulin fit tightly together. The operator holds the handle of the splicing machine body 1 and pushes the splicing machine forward at a uniform speed along the tarpaulin seam, continuously heating and pressing the overlap area to achieve continuous and seamless splicing of the tarpaulin. When the splicing machine body 1 moves forward, it can drive the guide frames 2 on both sides to slide forward in the guide rails 3, so that the splicing machine body 1 can only move back and forth.

[0035] After most of the tarpaulin has been spliced, the remaining small unspun sections at the front and back of the tarpaulin can be moved back by moving the entire device to expose or position the other parts of the tarpaulin on the main body 1 of the splicing machine, and then splicing can be performed.

[0036] Example 2: A method for processing fabric webs using a fabric web-splitting machine, comprising the following steps: Step 1, Equipment Installation: When splicing tarpaulins, first place two tarpaulins to be spliced ​​on the table. Then, install the telescopic cover 5 inside the mounting cover 4 with bolts. Next, slide the guide frame 2 into the telescopic cover 5. Then, place the two guide frames 2 horizontally on the table and press down the non-sponging parts of the tarpaulins. Then, the worker holds the splicing machine body 1 and places it on the table. At this time, the bottom ends of the two guide frames 2 are respectively inserted into the guide grooves of the two guide rails 3. Step 2, Adjusting the Spacing: Adjust the distance between the two guide frames 2 according to the length of the tarpaulin, so that the main body 1 of the splicing machine can move more easily. During the adjustment, the operator first moves one of the guide frames 2 to the side. The guide frame 2 drives the side adjustment rod 13 to move outward in the lower pressure plate 14. After moving to the appropriate position, stop. At this time, the limiting groove of the adjustment rod 13 is aligned with one of the limiting holes of the limiting frame 15 and the lower pressure plate 14. Then, the limiting post 16 is inserted into the limiting hole and the limiting groove to fix the adjustment rod 13. At the same time, the other guide frame 2 moves to the same position and distance, and at this time, the lower pressure plate 14 presses down on the tarpaulin to fix it. Step 3: Stabilize the guide frame 2: Then, the staff turns the handwheel 12, which drives the reciprocating screw 9 to rotate, thereby causing the slider 10 to move the adjusting frame 7 back and forth within the adjusting plate 6, and in turn, to move the friction plate 8 until the friction plate 8 is in contact with the side of the table, thereby fixing the guide frame 2. Step 4: Splicing the tarpaulin: After all the installation is completed, the staff starts the splicing machine body 1 and pushes it to splice the tarpaulin at the connection points.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
