Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a double-sided environmentally friendly printing equipment and a method thereof. Background Art

[0002] Double-sided environmentally friendly printing is a printing method that uses environmentally friendly materials to print on both sides of the product. It produces less pollution during the printing process, and the printed products are easy to recycle and reuse after being discarded. It is a printing method that can be naturally degraded and has little impact on the ecological environment. During the production and manufacturing process of woven bags, it is necessary to print patterns or characters on the front and back sides of the woven bags. During processing, the formed woven bags are placed between the printing roller and the receiving roller or the receiving plate. As the woven bags are transmitted between the printing roller and the receiving plate, the pattern on the printing roller can be transferred to the front side of the woven bag. In order to transfer the pattern to both sides of the woven bag, after the printing on one side of the woven bag is completed, the woven bag will be turned over and passed through the printing roller for a second time to realize printing on the other side of the woven bag.

[0003] Although some double-sided printing equipment arranges a printing roller at the top and bottom of the woven bag, and then the two printing rollers can print on both sides of the woven bag at the same time when the woven bag passes through the two printing rollers, in the actual printing process, because the woven bag contains two layers of woven materials stacked together, the woven materials at the top and bottom of the woven bag are prone to loosening and misalignment, resulting in misalignment of the printed patterns on the two sides of the woven bag. In addition, the woven bag itself has a certain length, and the transmission and conveying of the woven bag for printing cannot ensure that the woven bag is always in a taut state. When the wrinkles of the woven bag are loose, blank areas may appear in the wrinkled areas after printing, thus affecting the printing effect on both sides of the woven bag. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a double-sided environmentally friendly printing device and method thereof, wherein the woven bag is tensioned and arranged by a tensioning roller and an active roller, the motor rotates with the gear, and the gear engages with multiple transmission columns to enable the movable panel 2 to move linearly with the connecting rod and the fixed rod at different heights, and the printing roller on the fixed rod can roll on the top and bottom sides of the tensioned woven bag, so that the printing roller can print the two sides of the top and bottom of the woven bag. During the printing process, the receiving block can move inside the woven bag with the fixed rod, so that the woven bag can be supported on the outside of the printing roller, thereby improving the printing effect of the woven bag. As the printing roller moves on the top and bottom of the woven bag, the woven bag can be printed on both sides, and the woven bag is in a tensioned state during the printing process, which can effectively prevent the woven bag from having blanks in the wrinkled area after printing due to loose wrinkles.

[0015] A method for double-sided environmentally friendly printing equipment, the method specifically comprising the following steps:

[0016] Step 1: Put the woven bag between the tensioning roller and the driving roller, and place the receiving block inside the woven bag.

[0017] Step 2: Motor 3 drives the bidirectional screw to rotate, causing the movable seat to move the tensioning roller away from the active roller, tightening the woven bag between the tensioning roller and the active roller;

[0018] Step 3: Motor 2 drives the active roller to rotate so that the woven bag is transmitted between the tension roller and the active roller, so that the unprinted area near the two edges of the outer side of the woven bag is transmitted to the outer side of the tension roller or the active roller;

[0019] Step 4: Motor 1 drives the gear to mesh and rotate on the outside of the transmission column.

[0022] Step 7: The motor drives the corresponding synchronous pulley to rotate, so that the synchronous belt is transmitted between the two synchronous pulleys. The sponge block on the outside of the synchronous belt abuts against the outside of the printing roller and transfers the ink at the bottom of the ink tank to the outside of the printing roller.

[0023] Step 8: The printing roller coated with ink is scraped by a scraper during its rotation, so that the ink is evenly applied to the outside of the printing roller and the excess ink on the outside of the printing roller is scraped off.

[0024] Beneficial effects of the present invention:

[0025] 1. A support seat 2 is fixed on the top surface of the base, and the top of the support seat 2 is rotatably connected to the active roller. The inside of the base is rotatably connected to a bidirectional screw rod. Both ends of the bidirectional screw rod are screwed and connected to a movable seat that is slidably connected to the base. The top of the movable seat is rotatably connected to the tensioning roller. The woven bag to be printed is sleeved between the active roller and the tensioning roller. The rotation of the bidirectional screw rod causes the movable seat to move the tensioning roller away from the active roller, so that the active roller and the tensioning roller cooperate to tension and display the woven bags of different sizes (widths) that are not sewn at the bottom. The outer side of the support panel is slidably connected to the movable panel 1. The outer side of the movable panel 1 A movable panel 2 is slidably connected, and the gear on the top of the support seat 1 is driven by the motor 1 to engage with multiple transmission columns on the outside of the movable plate 2, thereby driving the movable panel 2 to move linearly with the connecting rod at different heights. The connecting rod drives the printing roller to roll on the top and bottom sides of the stretched woven bag through the fixed rod. During the rolling process, the printing roller prints the pattern on the woven bag, and as the printing roller moves on the top and bottom of the woven bag, the woven bag is printed on both sides. The woven bag is in a tensioned state during the printing process, which can effectively prevent the woven bag from having blanks in the wrinkled area after printing due to the relaxation of wrinkles.

[0026] 2. Two traction springs are arranged on the outside of the driving rod, one end of the traction spring is fixed to the outside of the fixed rod, and the other end of the traction spring is fixed to the outside of the driving rod. A receiving block is slidably connected to the top of the base, and the receiving block is arranged inside the woven bag. During the printing process, the connecting rod moves the printing roller on the fixed rod, and the fixed rod moves synchronously with the driving rod. The bottom end of the driving rod moves synchronously with the receiving block inside the woven bag through the limiting column, and the receiving block abuts against the printing roller, so that the woven material of the woven bag is arranged between the receiving block and the printing roller, and the receiving block plays a role in supporting the woven bag. The function of the bag is to allow the printing roller to smoothly print the pattern on the woven bag. When one end of the receiving block moves to the position abutting the tensioning roller, the driving rod no longer moves with the receiving block. At this time, the driving rod rotates on the fixed rod, and one of the traction springs is gradually pulled up. The driving rod rotates to its bottom end and passes through the limit column. Then, it rotates to a vertical position under the elastic force of the traction spring. Then, during the reverse linear movement of the connecting rod, the driving rod again carries the receiving block from the other side of the limit column and moves synchronously with the printing roller, so that the printing roller is moved to different positions outside the woven bag. There is always a receiving block supporting the woven bag;

[0027] 3. The woven bag is tensioned and arranged by the active roller and the tensioning roller. The second motor drives the active roller to rotate so that the woven bag can be transmitted between the active roller and the tensioning roller, so that the edge positions on both sides of the woven bag are transmitted to the outside close to the active roller or the tensioning roller, so that the side of the woven bag to be printed with the pattern can be transmitted to the side that contacts the printing roller later, so as to adjust the position of the printed pattern of the woven bag according to needs. Connecting rods are fixed at both ends of the movable panel 2, and the ends of the connecting rods are rotatably connected to the printing rollers, so that the two printing rollers can print patterns on the two woven bags synchronously. Two synchronous pulleys are connected by rotating inside the ink tank. The two synchronous pulleys drive with the synchronous belt, so that the sponge block outside the synchronous belt can transfer the ink at the bottom of the ink tank to the outside of the printing roller. The printing roller moves to the instruction manual during the printing process. Figure 6 The printing roller rotates in the direction of the arrow, so that the excess ink can be scraped off after passing the scraper, and the ink is evenly applied to the printing roller. Moreover, when the printing roller is transferred to the bottom of the woven bag for rolling printing, the printing roller can still rotate in the direction of the arrow for printing, so that the printing roller can rotate in the same direction when printing on the top or bottom side of the woven bag.

A woven bag is placed between the active roller 121 and the tensioning roller 511, and a receiving block 600 is arranged in the middle of the woven bag. A driving mechanism 700 is provided between the receiving block 600 and the fixed rod 300 at the corresponding position.

[0040] The ink supply module 400 includes a fixing plate 410 fixedly connected to the fixing rod 300, an ink tank 420 is fixed at one end of the fixing plate 410, an ink cartridge 430 is fixed inside the ink tank 420, an ink coating assembly 440 for coating ink on the printing roller 310 is provided inside the ink tank 420, a scraper 450 in contact with the printing roller 310 is fixed at the inner top of the ink tank 420, the ink tank 430 is convenient for temporarily storing ink and releasing the ink to the inner bottom of the ink tank 420 for use by the printing roller 310, and the scraper 450 can scrape off excess ink on the printing roller 310; a supply pipe 431 is fixed to the top of one end of the ink cartridge 430, and a plurality of ink cartridges 430 are fixed to the bottom surface of the ink cartridge 430 for supplying ink to the ink cartridge 310. The ink tank 420 releases the ink through the oil outlet pipe, and the supply pipe 431 facilitates the delivery of ink to the ink tank 430. The oil outlet pipe can transfer the ink inside the ink tank 430 into the ink tank 420; the top surface of the fixed plate 410 is fixed with a motor 460 for driving the corresponding position synchronous pulley 441 to rotate, and the outer side of the movable panel 2 230 is fixed with a groove-shaped limit bar 1 231 and a limit bar 2 232.

[0041] The inking assembly 440 includes two synchronous pulleys 441, both of which are rotatably connected to the ink box 420. A synchronous belt 442 is connected between the two synchronous pulleys 441. A sponge block is fixed to the outside of the synchronous belt 442. A through hole is opened on the side of the ink box 420 close to the printing roller 310. The sponge block at the through hole position abuts against the printing roller 310. The synchronous belt 442 drives the sponge block and transfers the ink on the sponge block to the printing roller 310 at the through hole position. The driving mechanism 700 includes a driving rod 710 rotatably connected to the fixed rod 300. Two traction springs 72 are arranged on the outside of the top of the driving rod 710. 0, the two ends of the traction spring 720 are respectively fixed with a connecting plate 1 730 and a connecting plate 2 740, the connecting plate 1 730 is fixedly connected to the fixed rod 300, and the connecting plate 2 740 is fixedly connected to the driving rod 710, and the traction spring 720 pulls the driving rod 710. When the limiting column 610 on the receiving block 600 does not move, the driving rod 710 can rotate on the fixed rod 300 and leave the limiting column 610, so that the traction spring 720 is in a stretched state. After the driving rod 710 leaves the limiting column 610, the elastic force of the traction spring 720 enables the rotated driving rod 710 to rotate to a vertical state.

[0042] One end of the receiving block 600 is fixed with a limiting column 610 that is in contact with the driving rod 710. The inner top and inner bottom of the receiving block 600 are embedded with a heating block. Both sides of the receiving block 600 are provided with an arc-shaped notch. The heating block uses a resistance wire to heat, which is a prior art. The heating block enables the woven bag to dry the ink in time after printing.

[0043] A method for double-sided environmentally friendly printing equipment, the method specifically comprises the following steps:

[0044] Step 1: The woven bag is conveniently placed between the tensioning roller 511 and the active roller 121, and the receiving block 600 is also arranged inside the woven bag;

[0045] Step 2: The motor 3 130 drives the bidirectional screw 500 to rotate, causing the movable seat 510 to move the tensioning roller 511 away from the active roller 121, thereby tightening the woven bag between the tensioning roller 511 and the active roller 121;

[0046] Step 3: The second motor 122 drives the active roller 121 to rotate so that the woven bag is transmitted between the tensioning roller 511 and the active roller 121, so that the unprinted areas near the two edges of the outer side of the woven bag are transmitted to the outer side of the tensioning roller 511 or the active roller 121;

[0047] Step 4: The motor 111 drives the gear 112 to engage and rotate on the outside of the transmission column 240. At this time, the transmission column 240 on the movable panel 230 is driven to the bottom of the gear 112. The printing roller 310 rolls and moves on the woven bag. The printing roller 310 prints the pattern on the bottom surface of the woven bag.

[0048] Step 5: The printing roller 310 is transferred to the top of the woven bag. The printing roller 310 moves outside the top of the woven bag to print the pattern on the top side of the woven bag.

[0049] Step 6: The bottom end of the driving rod 710 outside the fixing rod 300 moves synchronously with the receiving block 600 inside the woven bag through the limiting column 610. The sliding seat 620 on the receiving block 600 slides on the base 100, so that the woven material of the woven bag is arranged between the receiving block 600 and the printing roller 310.

[0050] Step 7: The motor 460 rotates the corresponding synchronous pulley 441, causing the synchronous belt 442 to transmit power between the two synchronous pulleys 441. The sponge block on the outside of the synchronous belt 442 abuts against the outside of the printing roller 310, and transfers the ink at the bottom of the ink tank 420 to the outside of the printing roller 310.

[0051] Step eight: The printing roller 310 coated with ink is scraped by the scraper 450 during its rotation, so that the ink is evenly coated on the outside of the printing roller 310 and excess ink on the outside of the printing roller 310 is scraped off.

[0052] Working principle: When using, in the initial state, refer to the instructions Figure 9, the printing roller 310 is arranged on one side of the woven bag, and the motor three 130 drives the bidirectional screw rod 500 to rotate so that the movable seat 510 moves toward the direction close to the support seat 2 120, so that the distance between the tensioning roller 511 and the active roller 121 is smaller. At this time, the woven bag can be conveniently sleeved between the tensioning roller 511 and the active roller 121, and the receiving block 600 is also arranged inside the woven bag, wherein the bottom end of the woven bag is not sewn and connected, and then the motor three 130 drives the bidirectional screw rod 500 to rotate in the opposite direction to make the movable seat 510 move closer to the support seat 2 120, so that the distance between the tensioning roller 511 and the active roller 121 is smaller. The seat 510 moves the tensioning roller 511 in the direction away from the active roller 121, tightening the woven bag between the tensioning roller 511 and the active roller 121, and then the motor 2 122 rotates the active roller 121 to transmit the woven bag between the tensioning roller 511 and the active roller 121, so that the unprinted area near the two edges of the outer side of the woven bag is transmitted to the outside of the tensioning roller 511 or the active roller 121, and then the motor 1 111 drives the gear 112 to engage and rotate on the outside of the transmission column 240, refer to the instructions Figure 10 At this time, the transmission column 240 on the movable panel 230 is driven to the bottom of the gear 112, and the fixed rod 300 on the connecting rod 250 of the movable panel 230 moves the printing roller 310 to the bottom of the woven bag. As the printing roller 310 rolls and moves on the woven bag, the printing roller 310 prints the pattern on the bottom surface of the woven bag. As the gear 112 continues to drive the multiple transmission columns 240 to move the movable panel 230, and the movable panel 1 220 moves on the supporting panel 210, the printing roller 310 is transferred to the top of the woven bag (refer to the instructions Figure 1), as the printing roller 310 moves on the top outside of the woven bag, a pattern is printed on the top side of the woven bag. In the process of moving the printing roller 310 on the fixed rod 300 with the connecting rod 250, the bottom end of the driving rod 710 on the outside of the fixed rod 300 moves synchronously with the receiving block 600 inside the woven bag through the limiting column 610. The sliding seat 620 on the receiving block 600 slides on the base 100, and the receiving block 600 abuts against the printing roller 310, so that the woven material of the woven bag is arranged between the receiving block 600 and the printing roller 310. The receiving block 600 plays the role of supporting the woven bag so that the printing roller 310 can smoothly print the pattern on the woven bag. When one end of the receiving block 600 moves to the position abutting the tensioning roller 511, the driving rod 710 no longer moves with the receiving block 600. At this time, the driving rod 710 rotates on the fixed rod 300, and one of the traction springs 720 is gradually pulled up, and the driving rod 710 rotates to its The bottom end passes through the limit column 610, and then the driving rod 710 is rotated to the vertical position under the elastic force of the traction spring 720. Then, during the reverse linear movement of the connecting rod 250, the driving rod 710 again carries the receiving block 600 from the other side of the limit column 610 to move synchronously with the printing roller 310, so that the receiving block 600 supports the woven bag when the printing roller 310 moves to different positions outside the woven bag. During the rolling of the printing roller 310, the motor 460 drives the corresponding position synchronous pulley 441 to rotate, so that the synchronous belt 442 is transmitted between the two synchronous pulleys 441. The sponge block on the outside of the synchronous belt 442 abuts against the outside of the printing roller 310 and transfers the ink at the bottom of the ink box 420 to the outside of the printing roller 310. The printing roller 310 coated with ink is scraped by the scraper 450 during the rotation, which facilitates the ink to be evenly applied to the outside of the printing roller 310 and scrapes off the excess ink on the outside of the printing roller 310.
