Description

Technical Field

[0001] The invention relates to the technical field of corrugated roller processing, in particular to a corrugated roller grinding device. Background Art

[0002] In the process of corrugated paper processing, corrugated rollers are needed to press and deform the paperboard to form a corrugated structure. The surface of the corrugated roller has corrugated grooves with a width of about 5mm, which determine the corrugated shape and strength of the corrugated paper.

[0003] In order to ensure the accuracy of the corrugated grooves pressed by the corrugated roller, each corrugated groove of the corrugated roller needs to be accurately ground and polished during processing. At present, the main method for grinding the corrugated grooves of the corrugated roller is "bottom positioning and top grinding". Specifically, the corrugated roller is first set up, and then a positioning block is set on the bottom side of the corrugated roller. The positioning block is inserted into the bottom side corrugated groove of the corrugated roller to position the corrugated roller circumferentially, and then the corrugated groove on the opposite side of the positioning block is ground; after completing the grinding of one corrugated groove, rotate a certain angle, reposition the other bottom side corrugated groove, and grind the corrugated groove on the opposite side of the positioning block again, and the grinding of each corrugated groove is completed in this cycle.

[0004] When the grinding disc is positioned using a conventional three-axis grinder, the system error of the three-axis grinder causes deviations in the contact force between the grinding disc and the corrugated groove when processing different corrugated grooves. When the cutting depth between the grinding disc and the corrugated groove is too large, the grinding disc wears more, and the surface quality and shape and position accuracy of the corrugated groove are reduced.

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0044] Combine the following Figures 1 to 7 Embodiments of the present invention are described.

[0045] This embodiment relates to a corrugated roller grinding device, and the grinding disc 44 has a high consistency in the amount of cutting each time when grinding the corrugated groove, which can better ensure the consistency of each corrugated groove. Among them, the corrugated roller refers to a tool used to press corrugated paper.

[0046] A corrugated roller grinding device in this embodiment includes:

[0047] frame;

[0048] A clamping roller mechanism 1, used for clamping the corrugated roller;

[0049] A driving motor 2, used to drive the clamping roller mechanism 1 to rotate;

[0050] The orientation mechanism 3 includes an orientation linear driver 31 disposed on the frame and an orientation plug 32 driven by the orientation linear driver 31 to move up and down;

[0051] The grinding mechanism 4 comprises a slide rail 41 arranged on a frame, a slide seat 42 sliding along the slide rail 41, a grinding motor 43 arranged on the slide seat 42, and a grinding disc 44 driven by the grinding motor 43. When the grinding disc 44 moves to the lower end of the sliding stroke along with the slide seat 42, the grinding disc 44 completes the grinding process of the corrugated groove;

[0052] The loading mechanism 5 includes a reel 51, a sling 52, and a load block 53 connected to the reel 51 through the sling 52, the load block 53 is placed on the slide 42 to provide pressure to the grinding disc 44 on the corrugated groove, and the reel 51 is used to lift the load block 53;

[0053] The feeding mechanism drives the driving motor 2 and the clamping roller mechanism 1 to feed along the axial direction of the corrugating roller.

[0054] When the grinding disc 44 is grinding the corrugated groove, since the weight of the load block 53 is constant, when the grinding disc 44 of the grinding device is working, the maximum contact force between the grinding disc 44 and the corrugated groove is consistent each time the grinding disc 44 grinds the corrugated groove, the maximum cutting amount between the grinding disc 44 and the corrugated groove is consistent, the grinding disc 44 is not easy to wear, and the surface quality of the corrugated groove after processing is good.

[0055] When the grinding disc 44 of the grinding device is used to grind the corrugated groove, the cutting amount of the corrugated groove driven by the feeding mechanism to grind the grinding disc 44 in a single time is determined by the loading force of the load block 53 on the slide 42 and the grinding disc 44, and the final grinding amount of the corrugated groove is determined by the bottom end position of the sliding stroke of the slide 42.

[0056] In addition, the corrugated roller grinding device disclosed in the present invention is loaded by the load block 53 when the grinding disc 44 is grinding, which can effectively reduce the vibration amplitude of the grinding disc 44 when it is working, improve the grinding accuracy, and improve the grinding efficiency. Compared with the structure that uses a cylinder, an oil cylinder, etc. to maintain a fixed structure through a compressible medium, it can effectively reduce the overall vibration of the grinding disc 44 during the grinding process.

[0057] Generally speaking, when determining the single cutting amount, the single cutting amount is set to 1 / 3 to 1 / 4 of the final grinding amount to cover the accumulated error of the corrugated groove of the corrugated roller in the previous process. Finally, it takes 3 to 4 reciprocating processes to make the slide 42 reach the bottom of the sliding stroke, so that the grinding amount of the corrugated groove surface reaches the final grinding amount, and the grinding of a single corrugated roller is completed.

[0058] The specific steps of using the corrugated roller grinding device include:

[0059] Positioning steps: the reel 51 reels the sling 52 to lift the load block 53; the corrugated roller to be sharpened is clamped by the roller clamping mechanism 1, the driving motor 2 is started to slightly rotate the corrugated roller, so that the bottom corrugated groove of the corrugated roller is aligned with the directional insert block 32, and the directional linear drive 31 of the directional mechanism 3 inserts the directional insert block 32 into the bottom corrugated groove to perform circumferential positioning of the corrugated roller;

[0060] Grinding steps: start the grinding motor 43, and at the same time, the reel 51 unwinds the sling 52, so that the load block 53 descends and presses the slide 42. At this time, the grinding disc 44 contacts the corrugated groove under the action of the load block 53, the maximum contact force between the grinding disc 44 and the corrugated groove is constant, the maximum cutting amount is constant, and the feeding mechanism drives the grinding disc 44 and the corrugated roller to move relatively along the axis direction of the corrugated roller;

[0061] Reset step: lift the load block 53 through the reel 51 to make the grinding disc 44 leave the corrugated groove being processed this time.

[0062] At this point, the positioning step, the grinding step, and the resetting step have completely completed the action of grinding the corrugated groove. The above-mentioned action of grinding the corrugated groove needs to be repeated several times for a corrugated roller so that the corrugated groove can reach the final grinding amount.

[0063] For the grinding of the remaining corrugated grooves, slightly rotate the corrugated roller so that the positioning block takes the other bottom corrugated groove on the side as the positioning target, and then repeat the positioning step, grinding step, and reset step again. Repeat this process to complete the processing of all the corrugated grooves.

[0064] It should be noted that when the remaining grinding amount is less than the grinding amount of a single processing, for example, the number of grinding times is set to 4 times, and the final grinding amount is set to 4μm, when the remaining grinding amount of the corrugated groove is less than 1μm, since the slide 42 has reached the bottom of the sliding stroke, the position of the grinding wheel is limited by the position of the slide 42, and the actual grinding amount of the corrugated groove by the grinding wheel 44 in this grinding process is small.

[0065] When the corrugated roller is loaded, in order to improve the convenience of installation, the grinding mechanism 4 also includes a cable 54, and the reel 51 is connected to the slide 42 through the cable 54. In this way, when the reel 51 lifts the load block 53, the slide 42 can also be lifted at the same time, so as to make enough space for the corrugated roller to be loaded into the clamping roller mechanism 1. In order to ensure that the reel 51 can lift the slide 42 and the load block 53 in an orderly manner and reduce the load when the reel 51 starts to lift, the length of the sling 52 and the cable 54 should be designed as follows: when the reel 51 is reeled, the load block 53 is first lifted to leave the slide 42 by the sling 52, and then the load block 53 and the slide 42 are lifted together by the cable 54 and the sling 52.

[0066] During actual processing, since a single corrugated groove needs to be ground multiple times, in order to improve the grinding efficiency, in the grinding device disclosed in the present invention, the number of the grinding mechanisms 4 is two groups, and the two groups of grinding mechanisms 4 are mirror-symmetrically arranged about the vertical plane passing through the axis of the corrugated roller, so that the grinding device disclosed in the present invention can grind two corrugated grooves at the same time, thereby improving the grinding efficiency.

[0067] Of course, in the grinding device including two sets of grinding mechanisms, the rotation of the corrugating roller may not be the same angle every time. The following takes a corrugating roller including 12 corrugating grooves as an example to illustrate the processing principle of this grinding device, as follows:

[0068] Before the actual processing, the corrugated grooves are numbered in sequence, specifically c1, c2, c3...c12, and the processing spacing is set to 2 corrugated grooves. Assume that the first round processes corrugated grooves c1 and c4; before the second round of processing, the corrugated roller rotates one grid to process corrugated grooves c2 and c5; before the third round of processing, the corrugated roller rotates one grid again to process corrugated grooves c3 and c6. Before the fourth round of processing, the corrugated roller needs to rotate 4 grids to process corrugated grooves c7 and c10. And so on, until one of the rounds (called the end round) completes the processing of the last numbered corrugated groove c12, that is, the processing of all the corrugated grooves is completed. It should be noted that in order to complete the processing of all the corrugated grooves when the end round is completed, the relationship between the number of corrugated grooves n and the processing spacing d should be that n can be divided by d.

[0069] Ideally, the two top side corrugated grooves are mirror-symmetrical about the vertical plane passing through the axis of the corrugated roller, and the depths of the two top side corrugated grooves are consistent, and the grinding time required is consistent. However, due to processing errors and the order of processing, the depths of the two top side corrugated grooves may be different during actual processing.

[0070] In order to conveniently identify whether the depths of the two top side corrugated grooves are different, the grinding device also includes a gravity detection component 6. The top sides of the two slide seats 42 are provided with installation grooves. The number of the gravity detection components 6 is two groups, and the two groups of gravity detection components 6 are respectively arranged at the two installation grooves. The gravity detection component 6 includes a first spring column 61, a first spring 62, a first push plate 63 and a pressure sensor 64. The first spring column 61, the first spring 62, the first push plate 63, and the pressure sensor 64 are placed in the installation groove from the outside to the inside in sequence. The first spring column 61 is supported by the first spring 62 to above the notch of the installation groove. The first spring column 61 supports the load block 53, and the load block 53 slides in the up and down directions.

[0071] When the depths of the two top side corrugated grooves are inconsistent, the top side corrugated groove with a shallower depth lifts the first spring column 61 higher through the first spring 62, and the load block 53 is placed on the slide 42. When the pressure sensor 64 is pressed by the first spring column 61, the first spring 62, and the first push plate 63, since the grinding disc 44 on the shallower side is shorter than the bottom surface of the load block 53, the compression amount of the first spring 62 on the shallower side is larger, and the detection value of the pressure sensor 64 on the shallower side is larger than the detection value of the pressure sensor 64 on the other side, so that the situation of different depths of the two top side corrugated grooves can be quickly identified. If the depth difference of the two top side corrugated grooves is too large, the operator is reminded to check and intervene in time by means of alarms. The gravity detection component 6 is equipped with a controller and a display screen in the prior art, and the numerical values ​​of the two pressure sensors 64 are displayed on the display screen, so that the operator can intuitively know the situation of different depths of the two top side corrugated grooves.

[0072] Specifically, Figure 5 As shown, when the depth of the top corrugated groove on the right side is shallow, the interference between the first elastic column 61 on the right side and the load block 53 increases, forcing the compression of the first spring 62 below to increase, thereby increasing the value fed back by the pressure sensor 64 on the right side.

[0073] In the case of only one grinding mechanism 4, the maximum single cutting amount is determined by the weight Gz of the load block 53. The load block 53 causes the grinding disc 44 to exert a force Fz=Gz on the grinding surface of the corrugated groove through the slide 42.

[0074] When the two top side corrugated grooves are different, the value Fs fed back by the pressure sensor 64 on the side with shallower top side corrugated groove depth is larger, while the value Fd fed back by the pressure sensor 64 on the side with deeper top side corrugated groove depth is smaller. At this time, Fs+Fd=Gz, the cutting amount and grinding amount of the side with shallower top side corrugated groove depth are larger, and the cutting amount and grinding amount of the side with deeper top side corrugated groove depth are smaller. Under the premise that the grinding disc 44 on the side with shallower top side corrugated groove depth and the grinding disc 44 on the side with deeper top side corrugated groove depth maintain the same rotation speed and feed speed, after completing the grinding of the corrugated groove, the depth difference of the two top side corrugated grooves can be reduced. In this way, the structure of two mirror-symmetrical grinding mechanisms 4 is adopted, which can improve the grinding efficiency and reduce the depth difference of the two top side corrugated grooves during subsequent grinding. In this way, at the last grinding (that is, the remaining grinding amount is less than the grinding amount of a single processing), the depth difference of the two top side corrugated grooves is basically eliminated, and finally the grinding effects of the two top side corrugated grooves tend to be consistent.

[0075] The aforementioned controller can be a mature product on the market such as STM32, 51 single chip microcomputer, PLC controller, etc. After obtaining the values ​​of the two gravity detection components 6, in addition to manual intervention to increase the grinding time, the grinding time can also be increased by automatic control.

[0076] In order to ensure that the center of gravity of the load block 53 remains on the aforementioned vertical plane after being repeatedly lifted and lowered by the sling 52, so as to improve the accuracy of gravity detection by the gravity detection component 6, a limit block 531 is provided on the lateral side of the load block 53, and a limit groove 8 is provided on the frame. The limit block 531 enables the load block 53 to slide along the limit groove 8, thereby ensuring that when the load block 53 is suspended, the bottom surface of the load block 53 remains in a horizontal state, thereby ensuring that the side of the pressure sensor 64 where the signal first appears can accurately correspond to the side of the corrugated groove of the corrugated roller with a shallower depth.

[0077] In order to further ensure the stability of the sliding of the load block 53, the limit slot 8 is in a "T" shape, and the limit block 531 is a "T"-shaped block, and the limit block 531 slides along the limit slot 8. Specifically, the "T"-shaped limit slot 8 is symmetrical about the vertical plane, and the center of gravity of the load block 53 also falls on the vertical plane, so as to ensure that when the limit block 531 slides along the limit slot 8, the center of gravity of the load block 53 remains on the vertical plane. The cross section of the limit block 531 is in a "T" shape, which matches the shape of the limit slot 8, so that the load block 53 only has the freedom to slide up and down, ensuring the accuracy of the repeated movement of the load block 53.

[0078] The structure of the corrugated roller is a cylinder with corrugated grooves (corrugated grooves) uniformly distributed on the surface. In actual production, the groove width and groove depth required for a single corrugated groove are different according to the thickness and material of the cardboard, resulting in different wrap angles of each corrugated groove. In order to ensure that the grinding device can adapt to grinding corrugated rollers with different wrap angles of corrugated grooves, the grinding device also includes an angle adjustment mechanism, which enables the two slides 42 to swing symmetrically around the axis of the corrugated roller, and the grinding disc 44 is detachably connected to the grinding motor 43.

[0079] like Figure 6As shown, taking a corrugated roller with 30 corrugated grooves as an example, since the corrugated grooves are arranged on the corrugated roller in a uniform arrangement, the wrap angle of each corrugated groove is 12°. At this time, when the angle between the two grinding discs 44 is a multiple of 12°, the two top side corrugated grooves can be aligned respectively. When switching to a corrugated roller with 36 corrugated grooves, the wrap angle of each corrugated groove is 10°. At this time, the angle between the two grinding discs 44 is adjusted to a multiple of 10° to align the two top side corrugated grooves respectively, so that the grinding device can adapt to grinding corrugated rollers with different numbers of corrugated grooves. In addition, the grinding disc 44 and the grinding motor 43 are detachable. When grinding different corrugated grooves, the grinding disc 44 with matching shape can be replaced to improve the grinding accuracy.

[0080] Specifically, the angle adjustment mechanism includes an angle adjustment telescopic rod 73, an angle adjustment guide groove 71, and an angle adjustment slider 72; the angle adjustment guide groove 71 is fixedly connected to the frame, and the angle adjustment guide groove 71 is an arc groove with the axis of the corrugated roller as the axis; the angle adjustment slider 72 is fixedly connected to the slide rail 41, and the angle adjustment slider 72 is an arc block with the same shape as the angle adjustment guide groove 71, and the angle adjustment slider 72 slides along the angle adjustment guide groove 71, and the angle adjustment telescopic rod 73 includes a drive seat 732 and a drive rod 731, the drive seat 732 is hinged to the frame, and the drive rod 731 is hinged to the slide rail 41;

[0081] There are two angle adjustment mechanisms, and the angle adjustment sliders 72 of the two angle adjustment mechanisms are respectively connected to a corresponding slide rail 41. The two angle adjustment mechanisms are arranged mirror-symmetrically about the vertical plane, and the angle adjustment telescopic rods 73 of the two angle adjustment mechanisms move synchronously in the same direction. In this embodiment, the back of the slide rail 41 is connected to the angle adjustment slider 72, and the angle adjustment slider 72 slides along the angle adjustment guide groove 71, so that the entire slide rail 41 can swing along the angle adjustment guide groove 71; the angle adjustment guide groove 71 is an arc groove with the axis of the corrugated roller as the axis center, so that the axis of the corrugated roller is the center when the slide rail 41 swings, simplifying the calculation of the adjustment angle and the required operation steps. When the angle of the slide rail 41 needs to be adjusted, the two angle adjustment telescopic rods 73 are started synchronously and in the same direction, so that the two angle adjustment drive rods 731 that are mirror-symmetrical to each other drive the two slide rails 41 to swing in opposite directions respectively, that is, the angles of the two slide rails 41 can be adjusted symmetrically, so that the grinding disc 44 can adapt to the corrugated grooves with different wrap angles for adjustment.

[0082] In this embodiment, the feeding mechanism is a linear module to ensure the accuracy of the feeding movement of the corrugating roller.

[0083] The driving motor 2 is a servo motor to ensure the accuracy of driving the corrugating roller to rotate.

[0084] The clamping roller mechanism 1 uses two cylinders to drive two core shafts to be inserted into the two ends of the axial hole of the corrugated roller to clamp the roller. One of the core shafts is connected to the drive motor 2, and the other core shaft is hinged to the cylinder. The cylinder and the drive motor 2 are both arranged on the feed mechanism and driven by the feed mechanism.

[0085] The angle-adjusting telescopic rod 73 adopts an electric push rod, which has the advantage of high movement accuracy.
