Description

Technical Field

[0001] The utility model relates to a transport mechanism for production equipment such as printing, film pasting, label pasting, etc., in particular to an intermittent feeding device with high production efficiency. Background Art

[0002] The printing equipment (or film or labeling equipment) is equipped with multiple functional rollers. The production materials are transported to the printing roller through the transmission roller for printing, and then pass through the drying device to dry the ink. Finally, it is rolled up by the receiving roller. According to different printing sizes, spacing, etc., it is necessary to select printing rollers (plate rollers) of different diameters, and the production operation is more troublesome.

[0003] Therefore, a current production method is to use a printing roller with a larger diameter, and to attach different printing templates according to production needs. For example, the attached printing template can completely cover the outer wall of the printing roller, or the attached printing template can only cover 3 / 4 of the outer wall of the printing roller, and the remaining 1 / 4 of the outer wall will become a non-working area. Therefore, a traction roller is installed at the front and rear ends of the transport device. When the working area of ​​3 / 4 of the printing roller rotates to the printing position, the traction roller rotates forward and normally pulls the production material forward. When the non-working area of ​​1 / 4 of the printing roller rotates to the printing position, the printing roller is equivalent to a non-working area. The traction roller reverses and pulls the production material backward, causing the production material to move backward until 3 / 4 of the working area of ​​the printing roller rotates back to the printing position, and the traction roller pulls the production material forward normally again (at this time, the production material is required to be exactly aligned with the previously printed pattern). This method does not require frequent replacement of the traction roller, and only requires the corresponding printing template to be installed (the actual speed needs to be adjusted according to the corresponding production, including the forward and backward speed of the traction roller, the rotation speed of the printing roller, etc.). At that time, due to the process of reversing the traction roller, this resulted in lower efficiency than the production method of only forward transportation. Summary of the invention

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0024] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-4 , an intermittent feeding device with high production efficiency, comprising a frame 1, on which a plate roller 2, a bottom roller 3 and a traction roller 4 are installed, a pressing area is formed between the plate roller 2 and the bottom roller 3, and a production material (such as Figure 1 , 2 The first floating roller 5 and the second floating roller 6 are respectively installed at the inlet and outlet ends of the embossing zone on the frame 1, and the sliding speeds of the first floating roller 5 and the second floating roller 6 are the same and the directions are opposite. The first floating roller 5 is installed at the feeding end of the first floating roller 5, and the second floating roller 6 is installed at the feeding end of the second floating roller 6. The production material is changed in direction by the first reversing roller 7, bypasses the lower side of the first floating roller 5, penetrates the embossing zone, and then changes in direction by the second reversing roller 8 and bypasses the second floating roller. 6, and finally, it is continuously pulled forward by the traction roller 4. The plate roller 2 can be mounted with embossing templates of different sizes to form corresponding working areas and non-working areas on the plate roller. There is no need to replace the entire plate roller according to production needs. The operation is simple and convenient. By sliding the first floating roller and the second floating roller upward or downward, the production materials outside the first floating roller and the second floating roller are normally transported forward at a uniform speed. The production materials between the first floating roller and the second floating roller are switched between forward and backward transportation to match the working area and the non-working area, thereby effectively improving the production efficiency of embossing.

[0026] When the non-working area of ​​the plate roller 2 rotates to the embossing area, the production material stops, and while waiting for the working area of ​​the plate roller 2 to rotate back to the embossing area, the production material continues to be transported forward to be paired with the previous embossing pattern. However, since it takes a certain amount of time for the production to stop and match the speed of the rotation of the plate roller 2, problems with the contrast of the embossing patterns may easily occur. Therefore, when the non-working area of ​​the plate roller 2 rotates to the embossing area, the production material needs to retreat a certain distance. Before the non-working area of ​​the plate roller 2 switches to the working area, the production material needs to start transporting forward until the production material is accelerated to the same speed as the rotation speed of the plate roller 2 (the embossing work is only performed when the speed of the plate roller 2 is consistent with the speed of the production material and is uniform), and the uniform speed is maintained. At this time, the working area of ​​the plate roller 2 just rotates to the embossing area.

[0027] When the working area of ​​the plate roller 2 leaves the embossing area, the production material decreases from a uniform forward speed to 0 speed, at which time it moves forward a short distance, then speeds up from 0 speed and moves in the opposite direction, at which time it moves backward a short distance, and this distance is greater than the distance the production material moves forward when it decreases from a uniform forward speed to 0 speed. At this time, it slows down to 0 speed again, then speeds up again, and moves forward at this time. When the production material speeds up to the same speed as the rotation speed of the plate roller 2, at this time, the working area of ​​the plate roller 2 just rotates to the embossing area again, and so on.

[0028] A fixed shaft 9 is installed on the frame 1, and a symmetrical mounting bracket 10 is rotatably mounted on the fixed shaft 9. The first floating roller 5 and the second floating roller 6 are respectively mounted at both ends of the mounting bracket 10. Similar to the principle of a seesaw, as long as the first floating roller 5 moves upward or downward, the second floating roller 6 will move in the opposite direction, and can effectively ensure that the speeds of the two are consistent.

[0029] The frame 1 is provided with a first driving wheel 11 located below the second floating roller 6 and a second driving wheel 12 located below the fixed shaft 9. A first reversing wheel 13 and a second reversing wheel 14 are provided on both sides of the second driving wheel 12, and the centers of the first reversing wheel 13 and the second reversing wheel 14 are lower than the center of the second driving wheel 12. A third reversing wheel 15 is provided below the first floating roller 5. A first driven wheel and a second driven wheel are provided on the first floating roller 5 and the second floating roller 6. The transmission belt 16 sequentially passes around the lower side of the first driving wheel 11, the lower side of the third reversing wheel 15, the upper side of the first driven wheel, the lower side of the first reversing wheel 13, the upper side of the second driving wheel 12, the lower side of the second reversing wheel 14, the upper side of the second driven wheel, and finally returns to the first driving wheel 11 to form a closed loop. Figure 2-4 shown.

[0030] The frame 1 is also provided with a fourth reversing wheel 25, and the transmission belt 16 passes around the lower side of the first driving wheel 11 and the upper side of the fourth reversing wheel 25 in sequence, and enters the lower side of the third reversing wheel 15, and the rest is consistent with the above description, such as Figure 2-4 As shown, the position of the first driving wheel 11 can be adjusted according to the installation space of the frame 1.

[0031] refer to Figure 3 , 4 , from the first driven wheel to the first reversing wheel 13 to the second driving wheel 12 is section B of the transmission belt, from the second driving wheel 12 to the second reversing wheel 14 to the second driven wheel is section C of the transmission belt, from the second driven wheel to the first driving wheel 11 is section D of the transmission belt, and from the first driving wheel 11 to the third reversing wheel 15 to the first driven wheel is section E of the transmission belt.

[0032] refer to Figure 3 When the first driving wheel 11 rotates clockwise (and always rotates clockwise at a constant speed) and the second driving wheel 12 stops rotating, sections B and C are stopped, and section D is transmitted to section E, thereby reducing the total length of sections C and D, and increasing the total length of sections B and E, the second floating roller 6 descends, and the first floating roller 5 rises.

[0033] When the second driving wheel 12 also rotates clockwise and its rotation speed is consistent with that of the first driving wheel 11, the second driving wheel 12 can be regarded as a reversing wheel, and the positions of the first floating roller 5 and the second floating roller 6 do not change (that is, it can be regarded as: the positions of all the reversing wheels, driven wheels, and driving wheels are fixed, and the driving wheel rotates, driving all the reversing wheels and driven wheels to rotate through the transmission belt 6).

[0034] refer to Figure 4 When the speed of the second driving wheel 12 is greater than that of the first driving wheel 11, segment D is transmitted to segment E, and segment B is transmitted to segment C at the same time, and the speed is higher than the speed of segment D to segment E, thereby increasing the total length of segments C and D, and reducing the total length of segments B and E, the second floating roller 6 rises, and the first floating roller 5 falls.

[0035] In addition, this product can also adopt other methods to achieve the effect that the sliding speeds of the first floating roller 5 and the second floating roller 6 are the same and the sliding directions are opposite, such as each is equipped with a linear motor, or a servo motor is used, and it is achieved through the transmission relationship between gears and racks.

[0036] Similarly, the positions of the first driving wheel 11, the second driving wheel 12 and each reversing wheel can be adjusted according to the actual installation space, and it is only necessary to ensure that the sliding speeds of the first floating roller 5 and the second floating roller 6 are the same and in opposite directions.

[0037] Two symmetrical first slide rails 17 are installed on the frame 1 along the vertical direction. First sliders 18 are slidably installed on the first slide rails 17. The first floating roller 5 and the second floating roller 6 are installed on the corresponding first sliders 18 respectively.

[0038] refer to Figure 2A third reversing roller 19 is installed at the discharge end of the first floating roller 5, the first reversing roller 7 and the third reversing roller 19 are tangent to the first floating roller 5, and the tangent line is in the vertical direction, the second reversing roller 8 is located directly above the second floating roller 6, the left side of the second reversing roller 8 and the left side of the second floating roller 6 are located on the same vertical line, the right side of the second floating roller 6 is tangent to the left side of the traction roller 4, and the tangent line is in the vertical direction, so that the production materials on both sides of the first floating roller 5 and the production materials on both sides of the second floating roller 6 are transported in the vertical direction, which is convenient for measuring the up and down moving distance of the first floating roller 5 and the second floating roller 6, thereby calculating the relationship between the rotation speed of the traction roller 4 and the transportation speed of the production materials.

[0039] In this embodiment, when the first floating roller 5 rises and the second floating roller 6 falls, it is a normal printing operation; during the overall operation of this product, the rotation speeds of the plate roller 2 and the traction roller 4 are uniform, and the speed at which the production material enters the first floating roller 5 and the speed at which the production material leaves the second floating roller 6 are also uniform and constant, and are consistent with the rotation speed of the traction roller 4. Since the moving directions of the first floating roller 5 and the second floating roller 6 are switched between up and down, the speeds of the first floating roller 5 and the second floating roller 6 are variable, namely: 0 speed - positive speed - 0 speed - reverse speed - 0 speed, and so on, positive and reverse are indications of the speed direction, and the positive speed and the reverse speed have acceleration, not uniform speed, and the relationship between the positive speed and the reverse speed is also variable. Therefore, what is more important is: the time required for the first floating roller 5 to rise from the lowest point to the highest point (due to the reciprocating motion, the positions of the lowest point and the highest point are unchanged, the first floating roller 5 descends in the same way, and the corresponding second floating roller 6 changes synchronously, and the first floating roller 5 is taken as an example below), which is related to the ratio of the working area to the non-working area on the plate roller 2. When the proportion of the working area is larger, that is, the proportion of normal printing time is longer, the first floating roller 5 rises longer, and the positive speed is slower. Correspondingly, the shorter the proportion of abnormal printing time is, the faster the first floating roller 5 descends, and the faster the reverse speed is. Therefore, it is necessary to adjust according to the actual situation (such as the size of the imprint template, the rotation speed of the plate roller 2 and the traction roller 4, etc.).

[0040] In this embodiment, the first floating roller 5 is similar to the second floating roller 6 in a movable pulley structure. When the first floating roller 5 descends, its descending height is H. Since there are production materials on both sides of the first floating roller 5, that is, the production materials need to provide a length of 2H for the first floating roller 5 to make the first floating roller 5 descend normally. Therefore, when the descending speed of the first floating roller 5 is half the speed of the traction roller 4, the production materials between the first floating roller 5 and the second floating roller 6 are stopped. When the descending speed of the first floating roller 5 is greater than half the speed of the traction roller 4, the length provided by the production materials is not enough to meet the descent of the first floating roller 5, so that the production materials from the embossing area to the second floating roller 6 are compensated to the first floating roller 5 to the embossing area, so that the production materials between the first floating roller 5 and the second floating roller 6 will retreat.

[0041] A steering roller 20 is installed between the embossing area and the third reversing roller 19 to adjust the angle of the protruding material entering the embossing area to ensure the embossing effect.

[0042] A drying mechanism 26 is installed between the discharge end of the embossing area and the second reversing roller 8. When the material to be embossed is ink or the like, the material is dried by the drying mechanism 26 to ensure the quality of the embossing effect.

[0043] A fourth reversing roller 21 is installed between the discharge end of the stamping area and the feed end of the drying mechanism 26, and a fifth reversing roller 22 is installed between the discharge end of the drying mechanism 26 and the second reversing roller 8. The fifth reversing roller 22 and the second reversing roller 8 are both used to adjust the angle of the production material entering the second floating roller 6 after leaving the drying mechanism 26.

[0044] A second slide rail 23 is installed on the frame 1 in the vertical direction, and a second slider 24 driven by a cylinder to slide is installed on the second slide rail 23. The plate roller 2 is installed on the second slider 24. When replacing the imprinting template, the plate roller 2 is raised by the cylinder, and after replacement, the plate roller 2 is lowered by the cylinder, thereby providing sufficient operating space for replacing the imprinting template, reducing the difficulty of operation, and improving the efficiency of replacement.

[0045] In this product, the plate roller 2, the traction roller 4 and each driving wheel can adopt a servo motor as a driving device.
