Description

Technical Field

[0001] This invention relates to the field of roll end cap pressing equipment, and in particular to an automatic roll end cap pressing device and its usage method. Background Technology

[0002] With the acceleration of urbanization and the continuous development of building structures, waterproof membranes are widely used in waterproofing projects in the construction industry. They are an indispensable part of infrastructure such as tunnel waterproofing, highway waterproofing, and landfill waterproofing, and also play an important role in waterproofing aquatic ecosystems. In the automated production of membranes, holes often appear at both ends of the membrane, requiring plugs to press in the outer packaging paper to ensure packaging integrity. However, this is currently still done manually. Due to the large volume and heavy weight of the membranes, manual operation is inefficient and poses safety hazards, and there is also the possibility of misalignment during transportation. Therefore, the design and development of an automatic plug-in device is of great significance for improving production efficiency and safety.

[0003] However, achieving automatic insertion of the roll end cap still faces many challenges. The primary goal is to ensure that the kraft paper can be gradually flattened, but due to the rigidity of kraft paper, it is difficult to insert it all at once. Therefore, how to press the kraft paper into the hole needs to be carefully considered to ensure that the designed device has stability, reliability, and safety.

[0004] Preliminary progress has been made in domestic research on roll packaging and automatic end-pressing devices, but this mainly focuses on softer materials such as pearl cotton and woven film, while kraft paper packaging is still largely done manually. With the booming development of trade globalization, the demand for packaging products of different sizes and specifications has expanded, and many companies' packing line workers are under long-term high-intensity work. Therefore, my country's packaging industry has an increasing demand for highly adaptable packaging equipment. Intelligent packaging equipment can shorten the packaging time for a single product, especially the time required for packaging products of different sizes in the same batch, reducing the workload of packing line workers and lowering the skill requirements. Therefore, digital optimization of packaging equipment operations and the intelligent transformation of equipment are imperative.

[0005] With rapid urbanization and continuous improvement and innovation in building structures, the demand for roll materials, an indispensable part of waterproof infrastructure construction, is steadily increasing. To extend the effective lifespan of roll materials while ensuring they resist moisture, corrosion, and damage, packaging is crucial. However, current manual packaging of roll materials still suffers from low efficiency, high cost, and significant safety hazards, thus urgently requiring a more intelligent and efficient kraft paper packaging solution. Traditional roll material end cap insertion relies heavily on manual operation, resulting in extremely high labor intensity. Automated devices can achieve continuous high-speed operation, significantly reducing production cycles, dependence on manual labor, and lowering enterprise labor costs. Since manual operation is susceptible to fatigue and varying skill levels, there is a possibility of deviations in end cap insertion or insufficient sealing. Automated devices, employing precise positioning and constant pressure control, ensure standardized end cap installation, reducing the proportion of defective products. Furthermore, the research process involves breakthroughs in key technologies such as high-precision sensing, adaptive control, and mechanical structure optimization, which can accumulate experience in the field of industrial automation, facilitate the technological upgrading of intelligent equipment, and help break foreign technological monopolies. In industrial automated production chains, the automatic roll end cap pressing device is a crucial link, and its development directly impacts production efficiency and product quality stability. By using high-precision pressing technology to achieve rapid and accurate bonding between the end cap and the roll material, errors from manual operation can be reduced, significantly improving the automation level of the production line and assisting traditional manufacturing in its transformation towards intelligent manufacturing. Therefore, the automatic roll end cap pressing device has significant production and promotion value.

[0006] In summary, designing an automatic roll end cap pressing device that features high efficiency, simple structure, low cost, and high degree of automation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic roll end cap pressing device and its usage method. This device features high efficiency, simple structure, low price, and high degree of automation. Through high-precision pressing technology, it enables the end cap and roll material to be quickly and accurately combined, reducing errors caused by manual operation, significantly improving the automation level of the production line, and assisting traditional manufacturing industries in their transformation towards intelligent manufacturing.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automatic roll end cap pressing device, comprising a frame, a kraft paper flattening device disposed on the frame, a kraft paper and end cap insertion device, and a pneumatic hammer impact pressing device; the kraft paper flattening device is disposed at the lower end of the frame, and the kraft paper and end cap insertion device and the pneumatic hammer impact pressing device are respectively disposed on the left and right sides of the kraft paper flattening device;

[0009] The kraft paper flattening device includes upper and lower plate support plates, and the upper and lower plate support plates are provided with multiple cylinder flattening components.

[0010] Preferably, the upper and lower support plates are disc-shaped, and multiple cylinder flattening components are distributed circumferentially and at equal intervals on the upper and lower support plates; each cylinder flattening component includes screws, cylinder connecting plates, first cylinders, cylinder piston rods, half hinges, hinge pins, cylinder connectors and cover plates;

[0011] The cylinder connecting plate is fixedly connected to the upper and lower plate support plates by screws and bolts. The first cylinder is installed on the cylinder connecting plate, which restricts the first cylinder to only move vertically. The front end of the first cylinder is connected to the cylinder piston rod. The two half-hinges are spliced ​​together to form a whole and fixed to the upper and lower plate support plates by hinge pins. The two half-hinges are spliced ​​together to form a whole and connected to the cover plate by hinge pins, so that the cover plate can move by opening and closing the half-hinges. The front end of the cylinder piston rod is connected to the cover plate through the cylinder connector. The movement of the cylinder piston rod in the first cylinder drives the movement of the cover plate, so that the cover plate can press the kraft paper, thereby completing the flattening of the kraft paper.

[0012] Preferably, the kraft paper and plug insertion device includes a first motor, a reducer, a motor bracket, a coupling, a bearing seat, a guide rail, a conversion device connecting rod, a connecting plate, a screw slide mechanism, a conversion connecting plate, a second cylinder, a rubber rod, a slide cylinder, and an automatically adjusting clamping claw;

[0013] The first motor is connected to the connecting rod of the conversion device through a reducer and a coupling to form a whole, and then fixed to the bearing seat, guide rail and screw slide mechanism through the motor bracket and connecting plate respectively; the lower end of the connecting rod of the conversion device is connected to the conversion connecting plate through a flange; one end of the conversion connecting plate is fixedly connected to the second cylinder in the vertical direction; the other end of the conversion connecting plate is fixedly connected to the slide cylinder; the piston rod of the cylinder in the second cylinder is connected to the rubber rod; and the slide cylinder is fixedly connected to the automatic adjustment jaw through its own connecting plate.

[0014] By adopting the above technical solution, the workflow is as follows: First, the motor in the screw slide mechanism drives the kraft paper and end-inserting device to move left and right via the screw slide mechanism and guide rail, allowing the rubber rod to move to the corresponding position. Under the action of the second cylinder, the rubber rod moves, initially inserting the kraft paper into the hole in the middle of the roll material. After the kraft paper is inserted, the screw slide mechanism and guide rail move to the left and stop. Then, the first motor rotates the connecting rod of the conversion device, causing the conversion connecting plate to rotate as well. This causes the automatic adjusting jaws to rotate to a certain position and stop. Then, the movement of the slide cylinder causes the automatic adjusting jaws to move downward, simultaneously inserting the end-inserting device into the kraft paper, thus completing the initial insertion of the end-inserting device.

[0015] Preferably, the automatically adjusting jaws include an outer plate, a third cylinder, a cylinder head, a slide groove, a cylindrical pin, a connecting jaw, and a V-jaw; the two outer plates are connected to each other to form the outer shell of the automatically adjusting jaws, the third cylinder is located between the two outer plates, the third cylinder is connected to the cylinder head, the cylinder head is connected to the slide groove, the slide groove is connected to the connecting jaw through the cylindrical pin, and the connecting jaw is connected to the V-jaw through a flat-head rivet.

[0016] By adopting the above technical solution: the cylinder head in the third cylinder moves to drive the slide groove to move. Since the slide groove is fixed to the connecting claw by the cylindrical pin, and the connecting claw and V claw are fixed to form a whole by the flat-head rivet, when the slide groove moves, it can drive the whole formed by the connecting claw and V claw to move, thus completing the gripping of the plug.

[0017] Preferably, the pneumatic hammer impact pressing device includes a ball screw, a second motor, a cylinder connecting rod, an impact cylinder, and a rubber hammer; the end of the ball screw is provided with a second motor, the ball screw is connected to the cylinder connecting rod, the lower end of the cylinder connecting rod is connected to the impact cylinder, and the impact cylinder is connected to the rubber hammer through a cylinder piston rod.

[0018] By adopting the above technical solution: the ball screw drives the air hammer impact pressing device to move left and right. When the rubber hammer reaches the corresponding position, the impact cylinder drives the rubber hammer to impact and press the inserted plug.

[0019] The present invention also provides a method for using an automatic roll end cap pressing device, the method comprising the following steps:

[0020] Step S1: First, wrap the waterproof membrane with kraft paper;

[0021] Step S2: The kraft paper is then flattened by the kraft paper flattening device. The movement of the cylinder piston rod in the first cylinder drives the movement of the cover plate, so that the cover plate can press the kraft paper tightly, thereby completing the flattening of the kraft paper.

[0022] Step S3: Then, the motor in the screw slide mechanism drives the kraft paper and the plug insertion device to move left and right through the screw slide mechanism and guide rail, so that the rubber rod can move above the kraft paper. Through the action of the second cylinder, the rubber rod is driven to move up and down, thereby pressing the kraft paper above the roll hole into the hole.

[0023] Step S4: Next, the motor in the screw slide mechanism drives the kraft paper and plug insertion device to move to the left, and then controls the automatic adjustment jaws to complete the clamping of the plug.

[0024] Step S5: The next step is to drive the kraft paper and plug insertion device to the right through the screw slide mechanism and guide rail by the motor in the screw slide mechanism. After stopping, the first motor causes the connecting rod of the conversion device to rotate, which in turn drives the conversion connecting plate to rotate. This causes the automatic adjusting jaws to rotate until they are aligned with the kraft paper and stop. Then, the movement of the slide cylinder causes the automatic adjusting jaws to move downward, and at the same time, the plug is inserted into the hole in the middle where the kraft paper has already been inserted, thus completing the placement of the plug.

[0025] Step S6: Next, the motor in the screw slide mechanism drives the kraft paper and plug insertion device to move to the left through the screw slide mechanism and guide rail, returning to the initial position, and the plug can be seen to be successfully placed.

[0026] Step S7: Move the air hammer impact clamping device to the left by the ball screw. After the rubber hammer reaches the corresponding position, the impact cylinder drives the rubber hammer to perform up and down impact to complete the clamping of the plug.

[0027] Step S8: The air hammer impact clamping device is moved to the right by the ball screw, so that the air hammer impact clamping device returns to its original position, the plug is successfully clamped, and the whole process ends.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. This invention employs a kraft paper flattening device, a kraft paper and end-insertion device, and a pneumatic hammer impact pressing device working together to achieve rapid and precise bonding of the end-insertion and roll material through high-precision pressing technology. This reduces errors from manual operation, significantly improves the automation level of the production line, and assists traditional manufacturing industries in their transformation towards intelligent manufacturing.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that those skilled in the art can better understand the advantages and features of the present invention, thereby making a clearer definition of the scope of protection of the present invention. The embodiments described in this invention are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] like Figure 1 As shown, an automatic roll end cap pressing device includes a frame 1, a kraft paper flattening device 2 disposed on the frame 1, a kraft paper and end cap insertion device 3, and a pneumatic hammer impact pressing device 4; wherein, the frame 1 is an aluminum alloy frame with high structural strength and light weight, the kraft paper flattening device 2 is disposed at the lower end of the frame 1, and the kraft paper and end cap insertion device 3 and the pneumatic hammer impact pressing device 4 are respectively disposed on the left and right sides of the kraft paper flattening device 2;

[0050] The kraft paper flattening device 2 includes upper and lower plate support plates 5, and the upper and lower plate support plates 5 are provided with multiple cylinder flattening components.

[0051] Specifically, such as Figure 2 As shown, the upper and lower plate support plates 5 are disc-shaped, and multiple cylinder flattening components are distributed circumferentially and at equal intervals on the upper and lower plate support plates 5; each cylinder flattening component includes screws 6, cylinder connecting plate 7, first cylinder 8, cylinder piston rod 9, half hinge 10, hinge pin 11, cylinder connector 12 and cover plate 13.

[0052] The cylinder connecting plate 7 is fixedly connected to the upper and lower plate support plates 5 by screws and bolts 6. The first cylinder 8 is installed on the cylinder connecting plate 7. Here, the cylinder connecting plate 7 restricts the first cylinder 8, allowing it to only move freely up and down. The front end of the first cylinder 8 is connected to the cylinder piston rod 9. The two half hinges 10 are spliced ​​together to form a whole and are fixed to the upper and lower plate support plates 5 by hinge pins 11. The two half hinges 10 are spliced ​​together to form a whole and are connected to the cover plate 13 by hinge pins 11, so that the cover plate 13 can move by opening and closing the half hinges 10. The front end of the cylinder piston rod 9 is connected to the cover plate 13 by the cylinder connector 12. The movement of the cylinder piston rod 9 in the first cylinder 8 drives the movement of the cover plate 13, so that the cover plate 13 can press the kraft paper, thereby completing the flattening of the kraft paper.

[0053] Specifically, such as Figure 3As shown, the kraft paper and plug insertion device 3 includes a first motor 14, a reducer 15, a motor bracket 16, a coupling 17, a bearing seat 18, a guide rail 19, a conversion device connecting rod 20, a connecting plate 21, a screw slide mechanism 22, a conversion connecting plate 23, a second cylinder 24, a rubber rod 25, a slide cylinder 26, and an automatic adjusting clamp 27;

[0054] The first motor 14 is connected to the conversion device connecting rod 20 through the reducer 15 and the coupling 17 to form a whole, and then fixed to the bearing seat 18, the guide rail 19 and the lead screw slide mechanism 22 through the motor bracket 16 and the connecting plate 21 respectively; the lower end of the conversion device connecting rod 20 is connected to the conversion connecting plate 23 through the flange; one end of the conversion connecting plate 23 is fixedly connected to the second cylinder 24 in the vertical direction; the other end of the conversion connecting plate 23 is fixedly connected to the slide cylinder 26; the cylinder piston rod in the second cylinder 24 is connected to the rubber rod 25; and the slide cylinder 26 is fixedly connected to the automatic adjustment jaw 27 through its own connecting plate.

[0055] The workflow of this embodiment is as follows: First, the motor in the screw slide mechanism 22 drives the kraft paper and end-insertion device 3 to move left and right via the screw slide mechanism 22 and guide rail 19, thereby moving the rubber rod 25 to the corresponding position. Under the action of the second cylinder 24, the rubber rod 25 is moved to initially insert the kraft paper into the hole in the middle of the roll material. After the insertion of the kraft paper is completed, the screw slide mechanism 22 and guide rail 19 move to the left and stop. Then, the first motor 14 causes the connecting rod 20 of the conversion device to rotate, which in turn causes the conversion connecting plate 23 to rotate. This causes the automatic adjusting jaw 27 to rotate to a certain position and stop. Then, the movement of the slide cylinder 26 causes the automatic adjusting jaw 27 to move downward, simultaneously inserting the end into the kraft paper, thus completing the initial insertion of the end.

[0056] Specifically, such as Figure 4 As shown, the automatically adjusting jaw 27 includes an outer plate 28, a third cylinder 29, a cylinder head 30, a sliding groove 31, a cylindrical pin 32, a connecting jaw 33 and a V-jaw 34, and a flat-head rivet 40. The two outer plates 28 are connected to each other to form the outer shell of the automatically adjusting jaw 27. The third cylinder 29 is located between the two outer plates 28 and is connected to the cylinder head 30. The cylinder head 30 is connected to the sliding groove 31. The sliding groove 31 is connected to the connecting jaw 33 via the cylindrical pin 32. The connecting jaw 33 is connected to the V-jaw 34 via the flat-head rivet 40. Figure 5 As shown, the slide groove 31 is in the shape of an "eight". The upper part of the slide groove 31 is connected to the cylinder head 30, and the lower left and right ends of the slide groove 31 are connected to the connecting claws 33 on both sides respectively.

[0057] In this embodiment: the cylinder head 30 in the third cylinder 29 moves to drive the slide 31 to move. Since the slide 31 is fixed to the connecting claw 33 by the cylindrical pin 32, and the connecting claw 33 and the V claw 34 are fixed together by the flat-head rivet 40, when the slide 31 moves, it can drive the whole formed by the connecting claw 33 and the V claw 34 to move, thus completing the gripping of the plug.

[0058] Specifically, such as Figure 6 As shown, the air hammer impact pressing device 4 includes a ball screw 35, a second motor 36, a cylinder connecting rod 37, an impact cylinder 38, and a rubber hammer 39; the end of the ball screw 35 is provided with the second motor 36, the ball screw 35 is connected to the cylinder connecting rod 37, the lower end of the cylinder connecting rod 37 is connected to the impact cylinder 38, and the impact cylinder 38 is connected to the rubber hammer 39 through the cylinder piston rod.

[0059] In this embodiment: the ball screw 35 drives the air hammer impact pressing device 4 to move left and right. When the rubber hammer 39 reaches the corresponding position, the impact cylinder 38 drives the rubber hammer 39 to impact and press the inserted plug.

[0060] Reference Figure 7-17 The present invention also provides a method for using an automatic roll end cap pressing device, the method comprising the following steps:

[0061] Step S1: First, wrap the waterproof membrane with kraft paper, such as... Figure 7 As shown;

[0062] Step S2: The kraft paper flattening device 2 then flattens the kraft paper. The movement of the piston rod 9 in the first cylinder 8 drives the movement of the cover plate 13, allowing the cover plate 13 to press the kraft paper firmly, thus completing the flattening process. Figure 8 As shown;

[0063] Step S3: Then, driven by the motor in the screw slide mechanism 22, the kraft paper and the plug insertion device 3 move left and right through the screw slide mechanism 22 and the guide rail 19, so that the rubber rod 25 moves above the kraft paper. Through the action of the second cylinder 24, the rubber rod 25 moves up and down, thereby pressing the kraft paper above the hole of the roll material into the hole. Figure 9 , Figure 10 As shown;

[0064] Step S4: Next, the motor in the lead screw slide mechanism 22 drives the kraft paper and plug insertion device 3 to move to the left, and then controls the automatic adjusting jaws 27 to complete the clamping of the plug, as shown. Figure 11 As shown,;

[0065] Step S5: The next step involves driving the kraft paper and plug insertion device 3 to the right via the screw slide mechanism 22 and guide rail 19. After stopping, the first motor 14 rotates the connecting rod 20 of the conversion device, causing the conversion connecting plate 23 to rotate as well. This rotates the automatic adjusting jaws 27 until they are aligned with the kraft paper. Then, the movement of the slide cylinder 26 causes the automatic adjusting jaws 27 to move downwards, simultaneously inserting the plug into the hole in the center where the kraft paper has already been inserted, thus completing the placement of the plug. Figure 12 , Figure 13 As shown;

[0066] Step S6: Next, the motor in the screw slide mechanism 22 drives the kraft paper and plug insertion device 3 to move to the left via the screw slide mechanism 22 and guide rail 19, returning to the initial position. The plug can be seen to be successfully placed. Figure 14 As shown;

[0067] Step S7: The ball screw 35 drives the air hammer impact clamping device 4 to move to the left. After the rubber hammer 39 reaches the corresponding position, the impact cylinder 38 drives the rubber hammer 39 to perform up-and-down impact action, completing the clamping of the plug. Figure 15 , Figure 16 As shown;

[0068] Step S8: The ball screw 35 drives the air hammer impact clamping device 4 to move to the right, causing the air hammer impact clamping device 4 to return to its original position, successfully clamping the plug, and the entire process ends. Figure 17 As shown.

[0069] In summary, this invention employs a kraft paper flattening device, a kraft paper and end-insertion device, and a pneumatic hammer impact pressing device working together. Through high-precision pressing technology, it facilitates the rapid and accurate bonding of the end-insertion and the roll material, reducing errors from manual operation, significantly improving the automation level of the production line, and assisting traditional manufacturing in its transformation towards intelligent manufacturing.

Step S5: The next step is to drive the kraft paper and plug insertion device (3) through the motor in the screw slide mechanism (22) to move to the right through the screw slide mechanism (22) and the guide rail (19). After stopping, the first motor (14) causes the conversion device connecting rod (20) to rotate, which in turn drives the conversion connecting plate (23) to rotate, thereby causing the automatic adjustment jaw (27) to rotate to be aligned with the kraft paper and stop. Then, the movement of the slide cylinder (26) causes the automatic adjustment jaw (27) to move downward, and at the same time, the plug is inserted into the hole in the middle where the kraft paper has been inserted, thus completing the placement of the plug. Step S6: Next, the motor in the screw slide mechanism (22) drives the kraft paper and plug insertion device (3) to move to the left through the screw slide mechanism (22) and the guide rail (19) and return to the initial position, and the plug can be seen to be successfully placed. Step S7: Drive the air hammer impact pressing device (4) to move to the left by the ball screw (35). After the rubber hammer (39) reaches the corresponding position, drive the rubber hammer (39) to perform up and down impact by the impact cylinder (38) to complete the pressing of the plug. Step S8: The air hammer impact pressing device (4) is moved to the right by the ball screw (35) so that the air hammer impact pressing device (4) returns to its original position and the plug is successfully pressed, and the whole process ends.
