Description

TECHNICAL FIELD

[0001] The application relates to the technical field of valve bag making machines, in particular to a paper feeding mechanism of an intelligent bottom pasting machine. BACKGROUND

[0002] The valve bag bottom pasting machine is a device specially used for producing valve bags, and the valve bags are widely used for filling powdery materials, granular materials and the like, such as cement, chemical fertilizer and grain. The bottom of the valve bag is usually closed through a bottom pasting process, so that the bottom of the bag is firm and can bear weight. Unlike ordinary paper bag making machines, the bottom of the valve bag needs special treatment to ensure its sealing, so as to prevent material leakage.

[0003] The working principle of the valve bag bottom pasting machine is similar to that of an ordinary paper bag bottom pasting machine, and the specific process is as follows: paper (usually paperboard or synthetic material) is fed into the bag making machine to ensure that the paper is transmitted to the bottom pasting device as required. The bottom of the paper bag is pre-folded into the shape required by the valve bag through a folding device. Glue is evenly applied to the bottom of the bag and the valve port area to ensure firm adhesion of the bag bottom and the valve port. The device is specially designed with a valve port device to form an opening at the bag port for filling materials. The valve port is usually reinforced by a hot or cold pressing device. The bag bottom is bonded by the hot or cold pressing device to ensure firm closure of the valve bag bottom and make the filling of materials more convenient. Finally, the complete valve bag is formed and cut into the required length by a cutting device, ready for loading.

[0004] In view of the above related technology, the paper feeding mechanism of the valve bag bottom pasting machine is fixed as a whole on the bottom pasting machine when segmenting the pasting paper, so when the paper is cut into different sizes, the original cutting part needs to be completely removed and replaced with a matching cutting part, which consumes a lot of time and reduces the installation efficiency of the paper feeding mechanism of the bottom pasting machine, thereby reducing the working efficiency of the bottom pasting machine.

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings attached to the specification Figures 1-10 and specific embodiments.

[0031] Reference Figure 1 and Figure 2The application discloses an intelligent pasting machine paper feeding mechanism, which comprises a mounting seat 1, a paper cutting assembly 2, a paper breaking assembly 3 and a scrap cleaning assembly 4. The paper cutting assembly 2 is installed on the upper end face of the mounting seat 1 and close to the edge, and the paper cutting assembly 2 is located at a position of the pasting machine far from the pasting mechanism. The paper breaking assembly 3 is installed on the upper end of the mounting seat 1 and close to the paper cutting assembly 2, and the paper breaking assembly 3 is located at a position of the pasting machine close to the pasting mechanism. The scrap cleaning assembly 4 is installed on the upper end face of the mounting seat 1 and close to the paper breaking assembly 3.

[0032] Paper is transported to the paper feeding mechanism, and the paper is pretreated, the paper cutting assembly 2 performs pre-segmentation on the paper, and the paper is pre-cut according to the requirements of the pasting machine. Then the paper breaking assembly 3 completely breaks the pre-segmented paper, so that the paper feeding mechanism can conveniently feed the single-section paper into the lower end of the bag body. The scrap cleaning assembly 4 cleans the debris on the surface of the single-section paper. The paper fed into the valve port bag body is in a clean and flat state.

[0033] Reference Figure 2 、 Figure 3 and Figure 4 The paper cutting assembly 2 comprises a first gear set 21, a first rotating drum 22, a cutter 23, a first fastening part 24 and a second rotating drum 25. The first gear set 21 is rotatably installed on the upper end of the mounting seat 1 and close to the edge, and the first gear set 21 comprises two same-specification gears which are in mesh with each other and rotate synchronously. The first rotating drum 22 is fixedly installed on the upper end of one of the gears, and the second rotating drum 25 is fixedly installed on the upper end of the other gear. A first plug-in groove 221 is formed in the outer side wall of the first rotating drum 22, and a plurality of first plug-in grooves 221 are uniformly distributed along the circumference of the first rotating drum 22. A butt joint groove 251 is formed in the outer side wall of the second rotating drum 25, and a plurality of butt joint grooves 251 are uniformly distributed along the circumference of the second rotating drum 25. The cutter 23 can be embedded in the butt joint groove 251, thereby protecting the blade of the cutter 23 and improving the paper cutting efficiency. The cutter 23 is plugged into the first plug-in groove 221 of the first rotating drum 22, and according to the requirements of the pasting paper size, the corresponding cutter 23 is plugged into the first plug-in groove 221, so as to control the length of the pasting paper. The cutter 23 is arranged in a break-point type, so that part of the paper at the breaking point is still in a connected state, thereby facilitating subsequent breaking and ensuring normal conveying of the paper. The first fastening part 24 is installed on the upper end of the first rotating drum 22 and used for pressing and fixing the cutter 23.

[0034] The first fastening part 24 comprises a fastening cover 241 and a pressing block 243. The fastening cover 241 is rotatably installed on the upper end of the first rotating drum 22. A plurality of through grooves 242 are formed on the upper end of the fastening cover 241 and are uniformly distributed along the circumferential direction of the fastening cover 241. The through grooves 242 are in communication with the first plug-in grooves 221 on the first rotating drum 22, facilitating the plug-in of the cutter 23. A plurality of pressing blocks 243 are arranged on the lower end of the fastening cover 241 and are uniformly distributed along the circumferential direction of the fastening cover 241. A plurality of receiving grooves 222 are formed on the upper end face of the first rotating drum 22 and are uniformly distributed along the circumferential direction of the first rotating drum 22. The pressing blocks 243 can be plugged into the receiving grooves 222. The pressing blocks 243 are arranged as elastic members.

[0035] Before formal work, the fastening cover 241 on the upper end of the first rotating drum 22 is rotated, so that the through grooves 242 on the fastening cover 241 are in alignment with the first plug-in grooves 221 on the first rotating drum 22, and the cutter handle of the cutter 23 can pass through the through grooves 242 and be plugged into the first plug-in grooves 221. When the fastening cover 241 is rotated, the pressing blocks 243 between the fastening cover 241 and the first rotating drum 22 are moved from the position of the first plug-in grooves 221 to the position of the receiving grooves 222. When the compressed pressing blocks 243 are moved to the position of the receiving grooves 222, they will restore their original shape and then be embedded in the receiving grooves 222, thereby reducing the possibility of accidental rotation of the fastening cover 241, aligning the through grooves 242 with the first plug-in grooves 221, and improving the efficiency of the cutter 23 installation. When installing the cutter 23, the corresponding cutter 23 should be installed on the corresponding position of the first rotating drum 22 according to the size requirement of the paper segmentation, and then the cutter 23 is plugged into the corresponding first plug-in groove 221. It is necessary to ensure that the distance between two adjacent cutters 23 is the same, and the more the number of cutters 23 on the first rotating drum 22, the smaller the length of the segmented paper. Since the cutter 23 is arranged as a breakpoint type blade, when the cutter 23 is plugged into the corresponding plug-in groove 251, the blade of the cutter 23 penetrates the local surface of the paper and cuts a discontinuous fracture on the paper. After the cutter 23 is plugged into the first plug-in groove 221, the fastening cover 241 is controlled to rotate back, so that the pressing blocks 243 slide out of the receiving grooves 222 and then move to the upper end of the first plug-in groove 221. The compressed pressing blocks 243 can abut against the upper end of the cutter 23, thereby improving the stability of the cutter 23 after installation;

[0036] In formal work, the first gear set 21 rotates to control the synchronous and reverse rotation of the first rotating drum 22 and the second rotating drum 25, the first rotating drum 22 drives the cutter 23 to move in the circumferential direction, when the first rotating drum 22 rotates to the cutter 23 can be inserted into the corresponding butt joint groove 251, the cutter 23 blade penetrates the paper, cuts the local position of the paper, so that the paper becomes a state convenient for complete disconnection. Because a plurality of cutters 23 can be quickly installed on the first rotating drum 22, the paper cutting assembly 2 can quickly switch between different paper segmentation specifications, improve the cutter 23 assembly speed of the paper feeding mechanism, and further improve the working efficiency of the paper feeding mechanism and the bottom pasting machine for valve port bags.

[0037] Reference Figure 1 、 Figure 2 and Figure 6 , the paper cutting assembly 3 includes a second gear set 31, a third rotating drum 32, a fourth rotating drum 33, a second fastening part 34, and a paper cutting part 35. The second gear set 31 is installed at the upper end of the mounting seat 1 and close to the first gear set 21, the second gear set 31 also includes two same specification gears meshing with each other, and the two gears rotate synchronously. The third rotating drum 32 is fixedly installed on one of the gears, and the fourth rotating drum 33 is fixedly installed on the other gear. Through the synchronous rotation of the two gears in the second gear set 31, the synchronous rotation of the third rotating drum 32 and the fourth rotating drum 33 is controlled. The outer side wall of the third rotating drum 32 is provided with a second insertion groove 321, and a plurality of second insertion grooves 321 are uniformly distributed along the circumferential direction of the third rotating drum 32. The paper cutting part 35 is inserted into the second insertion groove 321. The fourth rotating drum 33 has the same structure as the third rotating drum 32, and the fourth rotating drum 33 also has the paper cutting part 35 inserted thereon. The position of the paper cutting part 35 on the fourth rotating drum 33 is the same as that of the paper cutting part 35 on the third rotating drum 32, so as to ensure that the paper cutting parts 35 can abut each other. The second fastening part 34 is installed at the upper end of the third rotating drum 32 and the fourth rotating drum 33, and the structure of the second fastening part 34 is the same as that of the first fastening part 24. The second fastening part 34 is used to compress and fix the paper cutting part 35.

[0038] The paper cutting part 35 includes an insertion plate 351, a clamping plate 352 and a telescopic spring piece 353. The insertion plate 351 is inserted into the second insertion groove 321. The telescopic spring piece 353 is inserted into the outer side of the insertion plate 351, and a plurality of telescopic spring pieces 353 are uniformly distributed along the length direction of the insertion plate 351. The clamping plate 352 is fixedly installed at one end of the telescopic spring piece 353 away from the insertion plate 351. The clamping plate 352 located on the third rotating drum 32 can abut against the clamping plate 352 located on the fourth rotating drum 33. When the two clamping plates 352 abut against each other, the telescopic spring piece 353 can be retracted into the insertion plate 351.

[0039] Before formal work, according to the method of installing the cutter 23, according to the size requirement of the paper segmentation, the corresponding paper breaking part 35 is inserted into the second insertion slot 321, the paper breaking part 35 is fixed by the second fastening part 34, and the installation position of the paper breaking part 35 on the third rotating drum 32 and the fourth rotating drum 33 is the same, which ensures that the paper breaking part 35 on the third rotating drum 32 and the fourth rotating drum 33 can smoothly abut. When installing, rotate the second fastening part 34, and then insert the insertion plate 351 of the paper breaking part 35 into the corresponding second insertion slot 321. Then rotate the second fastening part 34 to fix the insertion plate 351, complete the debugging and installation of the paper breaking assembly 3;

[0040] After the paper is segmented and pretreated at the paper cutting assembly 2, the paper is conveyed between the third rotating drum 32 and the fourth rotating drum 33. With the rotation of the second gear set 31, the third rotating drum 32 and the fourth rotating drum 33 rotate synchronously and reversely, thereby driving the clamping plates 352 of the paper breaking part 35 to rotate circumferentially. When the clamping plates 352 on the third rotating drum 32 and the fourth rotating drum 33 are in contact with the surface of the paper synchronously, the expansion spring 353 is extruded, one end of the expansion spring 353 is inserted into the insertion plate 351, and with the conveying of the paper, the clamping plates 352 on both sides of the paper always abut against the surface of the paper. When the two clamping plates 352 are perpendicular to the paper, the expansion spring 353 cannot continue to stretch into the insertion plate 351. With the continuous movement of the paper, the expansion spring 353 can stretch out from the insertion plate 351, and the clamping plate 352 moves from one side of the second gear set 31 to the other side. At this time, the expansion spring 353 is extruded out of the insertion plate 351 due to the elastic force, and since the clamping plates 352 on both sides clamp the paper, when the expansion spring 353 is extruded out of the insertion plate 351, the paper is disconnected by the traction force generated by the displacement of the clamping plate 352, and the segmentation of the paper is completed.

[0041] Reference Figure 1 , Figure 2 and Figure 6The scrap removing assembly 4 comprises a fixed plate 41, a first guide rod 42, a second guide rod 43, a felt plate 44, a mounting portion 45, an air blower 46 and a dust collecting tray 47. The fixed plate 41 is mounted on the upper end of the mounting base 1. Two vertically distributed fixed plates 41 form a group, and two groups of fixed plates 41 are symmetrically distributed about the mounting base 1. The first guide rod 42 and the second guide rod 43 are mounted between the two vertically distributed fixed plates 41. The first guide rod 42 is fixedly mounted on one end of the fixed plate 41, and the second guide rod 43 is fixedly mounted on the other end of the fixed plate 41. The felt plate 44 is also mounted between the two vertically distributed fixed plates 41, and the felt plate 44 is located between the first guide rod 42 and the second guide rod 43. The mounting portion 45 is mounted on the upper end of the felt plate 44 and close to the first guide rod 42. The air blower 46 is fixedly mounted on the upper end of the mounting base 1 and close to the felt plate 44, and is used to suck paper scraps. The detachable dust collecting tray 47 is mounted on the lower end of the mounting base 1 and close to the air blower 46, and the dust collecting tray 47 is in communication with the air blower 46 and is used to accommodate the paper scraps sucked by the air blower 46.

[0042] The mounting portion 45 comprises a reset spring 451, a sleeve rod 452, a displacement plate 453 and a limiting rod 454. The sleeve rod 452 is fixedly mounted on both ends of the first guide rod 42, and two sleeve rods 452 are symmetrically distributed about the first guide rod 42. One end of the sleeve rod 452 is fixedly connected with the first guide rod 42, and the other end of the sleeve rod 452 is fixedly connected with the fixed plate 41. The reset spring 451 is sleeved on the outside of the sleeve rod 452, and one end of the reset spring 451 is fixedly connected with the fixed plate 41. The displacement plate 453 is sleeved on the outside of the sleeve rod 452, and the displacement plate 453 is fixedly connected with the other end of the reset spring 451. The limiting rod 454 is fixedly mounted on the displacement plate 453 and away from one end of the sleeve rod 452. The upper and lower ends of the felt plate 44 and close to the limiting rod 454 are provided with plug-in holes 456, and one end of the limiting rod 454 is plugged into the plug-in hole 456 on the felt plate 44. The fixed plate 41 is provided with a limiting slot 455, and the other end of the limiting rod 454 is plugged into the limiting slot 455 on the fixed plate 41, and the end of the limiting rod 454 plugged into the fixed plate 41 slides in the limiting slot 455.

[0043] Before formal work, the installation of the felt plate 44 is completed first. First, the displacement plate 453 is pulled towards the fixed plate 41, so that the reset spring 451 is compressed, and then the spacing between the upper and lower limiting rods 454 is increased. Then the plug-in hole 456 at the lower end of the felt plate 44 is sleeved on the lower limiting rod 454, the displacement plate 453 is loosened, the upper limiting rod 454 is plugged into the plug-in hole 456 at the upper end of the felt plate 44, and then the installation of the felt plate 44 is completed.

[0044] During operation, the paper cut by the paper-cutting assembly 3 moves between the two felt plates 44. The paper rubs against the felt plates 44, and the side of the felt plate 44 in contact with the paper smooths out wrinkles on the paper surface and removes debris and dust, improving the adhesion of the adhesive. The limiting rod 454 can slide within the limiting groove 455 on the fixed plate 41. Since the displacement plate 453 is fixedly connected to the return spring 451, and the return spring 451 is fixedly connected to the fixed plate 41, the return spring 451 can bring the two felt plates 44 together, increasing the contact area between the felt plates 44 and the paper, thereby increasing the debris removal effect. The debris removed by the felt plates 44 is sucked into the dust collection tray 47 by the blower 46. When debris accumulates in the dust collection tray 47, the dust collection tray 47 is disassembled and replaced to further clean the debris.

[0045] A method for using the paper feeding mechanism of an intelligent bottom gluing machine based on the above includes the following steps:

[0046] S1. Adjust the paper cutting assembly 2, rotate the fastening cover 241 of the first fastening part 24, and insert the cutter 23 into the corresponding first insertion slot 221 according to the paper segment size requirements. Then rotate the fastening cover 241 and use the clamping block 243 to fix the cutter 23.

[0047] S2. Adjust the paper cutting assembly 3, rotate the second fastening part 34, and according to the position of the cutter 23 installed on the paper cutting assembly 2, insert the insert plate 351 of the paper cutting part 35 into the second insertion slot 321, and at the same time make the insert plate 351 on the fourth rotating drum 33 and the insert plate 351 on the third rotating drum 32 in the same position. Then rotate the second fastening part 34 to fix the insert plate 351 of the paper cutting part 35.

[0048] S3. Install the chip removal assembly 4, lift the displacement plate 453 to compress the return spring 451, and then put the felt plate 44 between the upper and lower limit rods 454. Use the return spring 451 to limit the position of the felt plate 44 to complete the installation of the chip removal assembly 4.

[0049] S4. The first gear set 21 drives the first rotating drum 22 and the second rotating drum 25 to rotate. The paper is pre-segmented using the cutter 23 and the docking groove 251. The second gear set 31 drives the third rotating drum 32 and the fourth rotating drum 33 to rotate. The paper is clamped using the clamping plate 352. The clamping plate 352 is quickly moved using the telescopic spring 353, thereby quickly breaking the paper in the paper's forward direction and completing the paper segmentation process. The paper is then smoothed using the felt plate 44, and debris on the paper surface is cleaned. The debris is sucked into the dust collection tray 47 by the blower 46, completing the pre-treatment of the glued paper.

[0050] The working principle of this application embodiment:

[0051] Firstly, the debugging of the mechanism is completed, the fastening cover 241 of the first fastening part 24 is rotated to make the through slot 242 communicate with the first plug-in slot 221, then the cutter 23 is inserted into the corresponding first plug-in slot 221 according to the requirement of paper segmentation. Similarly, the second fastening part 34 is rotated to insert the paper breaking part 35 into the corresponding second plug-in slot 321. Then the displacement plate 453 is pulled to compress the return spring 451, the felt plate 44 is plugged into the lower end limiting rod 454, and then the displacement plate 453 is released to make the upper end limiting rod 454 plugged into the plug-in hole 456 on the felt plate 44. The debugging work of the paper feeding mechanism is completed;

[0052] In work, the first gear set 21 rotates to drive the first rotating drum 22 and the second rotating drum 25 to rotate synchronously and reversely, when the cutter 23 is embedded into the butt joint slot 251, the paper is penetrated by the cutter 23, and then the virtual line break is cut on the paper.
