Intermittent paper pattern roll-coating printing and dyeing mechanism

Abstract

The utility model relates to an intermittent paper pattern roller coating printing and dyeing mechanism which comprises a supporting piece with the upper end rotationally connected with a follower plate through a supporting shaft I. A cam is rotationally connected to the middle section of the follower plate, a positioning groove is formed in the side, away from the supporting shaft I, of the follower plate in a penetrating mode, and one side of the cam is rotationally connected with a driven plate. The side, away from the cam, of the driven plate is movably connected with a linkage rod and a printing and dyeing roller which are vertically arranged through a through hole, and the limiting groove is inserted into the through groove. In the actual use process, along with continuous rotation of the cam, the up-down swinging process of the follower plate can be intermittently completed by means of the structural characteristics of the cam, that is, although the printing and dyeing roller is driven by the cam to continuously do linear motion relative to the positioning groove, a user can replace the processing position on paper when the follower plate swings upwards. Compared with a device in the prior art, the device is simple in structure, and the machining time can be controlled more accurately.

Description

Technical Field

[0001] The utility model relates to the technical field of paper roller coating and dyeing, in particular to an intermittent paper pattern roller coating and dyeing mechanism. Background Art

[0002] Paper can be divided into many types according to the process, materials used and application, such as transfer paper, coated paper, facial tissue, plastic paper, etc.

[0003] Under the current processing mode, most papers need to be rolled by printing and dyeing rollers during the production process. Rolling the paper surface with printing and dyeing rollers can not only form characteristic patterns on the paper as needed to increase the aesthetics, but also for some papers, the indentation produced by rolling can be beneficial to subsequent processing and facilitate paper cutting.

[0004] In the prior art device, if it is necessary to intermittently (balance the paper feed speed and the rolling area) roll the paper with the printing roller, it is generally divided into two processing steps. The first step is to use the thrust mechanism to achieve the relative movement of the printing roller and the paper. At this time, the paper and the printing roller are tightly fitted. The second step is to use the lifting mechanism to lift the printing roller. At this time, there is a gap between the paper and the printing roller. The operator can move the paper to change the processing position. Repeating the above steps can complete the intermittent rolling process of the paper.

[0005] The existing device uses multiple mechanisms to complete the intermittent rolling process of paper. Although it has better adjustability and a wider range of applications, we found in the actual production process that more production equipment involved means that the device damage rate increases, the processing time is uncertain due to operator technical problems, and the mass production process does not require a larger adjustment range.

[0006] Therefore, we believe that we need an intermittent paper pattern roller coating and dyeing mechanism with a simpler structure and the ability to accurately control the processing time. Summary of the invention

[0007] In view of the shortcomings of the prior art, the utility model proposes an intermittent paper pattern roller coating printing and dyeing mechanism, which has the advantages of simple structure and controllable processing time, and solves the shortcomings of the prior art device such as uncontrollable processing time and high maintenance cost due to the large number of involved processing equipment.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] The invention relates to an intermittent paper pattern roller coating and dyeing mechanism, comprising a support member, the upper end of the support member is rotatably connected to a follower plate through a support shaft I, a positioning groove is provided on the follower plate through the front and rear, and the positioning groove and the support shaft I are respectively located on the left and right sides of the follower plate. The upper end of the support member is fixedly connected to a limiting shaft, and a front and rear axial cam is arranged on the upper end of the limiting shaft, and a driving mechanism is arranged on one side of the cam, and the cam and the follower plate are rotatably connected. The cam comprises a main body of a cylindrical structure, an extension part is coaxially fixedly connected to the outer side of the main body, and the cam abuts against the limiting shaft. A follower plate is rotatably connected to one side of the cam, and the follower plate and the cam extension part are symmetrically arranged with the cam center axis as the symmetry line. A through hole is respectively provided at the upper and lower ends of the follower plate away from the cam, and a linkage rod is inserted in the relatively upper through hole, and a printing and dyeing roller is inserted in the relatively lower through hole. The two axial ends of the linkage rod are inserted in the positioning groove, and the linkage rod and the positioning groove are clearance-matched.

[0010] Preferably, two limit shafts are arranged in parallel at the front and rear ends of the upper end of the support member, a cam is abutted against the upper end of each limit shaft, and each cam is equipped with a corresponding driving mechanism and a driven plate. The two driven plates are respectively located at the two axial ends of the printing and dyeing roller, and the smaller diameter parts of the two axial ends of the printing and dyeing roller are respectively inserted into the corresponding through holes on the two driven plates.

[0011] Preferably, the driving mechanism includes a driving motor fixedly connected to the follower plate, a driven gear is arranged on one side of the driving motor, the output shaft of the driving motor is transmission-connected to the driven gear, the middle section of the follower plate is rotationally connected to a support shaft II, the support shaft II is rotationally connected to the corresponding cam, and the driven gears corresponding to the remote ends of the two cams are coaxially and fixedly connected.

[0012] Preferably, a driving gear is coaxially fixedly connected to the output shaft of the driving motor, the driving gear is meshingly transmission-connected with the driven gear, and the diameter of the driving gear is smaller than the diameter of the driven gear, and the transmission ratio between the driving gear and the driven gear is not equal to one.

[0013] Preferably, when the cam body abuts against the limiting shaft, the lower end surface of the positioning groove is parallel to the horizontal plane.

[0014] Preferably, the angle of the fan-shaped structure corresponding to the cam extension is not less than 100° and not more than 150°, and the outer wall of the cam has a smooth transition.

[0015] Preferably, a bearing is sleeved on the outer side of each limiting shaft, and the bearing abuts against the cam.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model arranges a limiting shaft on the support member and constrains one end of the follower plate to be rotatably connected to the support member. Then, by utilizing the structural characteristics of the cam itself, the distance between the central axis of the cam and the limiting shaft can be changed during the rotation of the cam, thereby realizing the upward swinging process of the follower plate. This enables the printing and dyeing roller to continuously make a linear motion relative to the positioning groove, but the positioning groove can swing upward out of the processing position to allow the operator to replace the processing paper. Compared with the prior art device, this device not only has a simple structure, but also can more effectively control the processing time. It only needs to keep the cam rotating continuously to continuously complete the intermittent roller coating printing and dyeing work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] Please refer to Figure 1-5 An intermittent paper pattern roller printing and dyeing mechanism includes a support member 1 which plays a major supporting role. In practice, the support member 1 can be replaced by a corresponding workbench, and the support member 1 can be regarded as a reference point of the device.

[0027] It should be noted that the device is provided with a printing roller 6 on one side of the support 1. When the printing roller 6 makes horizontal linear motion, the paper to be processed can be subjected to a roller coating printing and dyeing process. When the printing roller 6 is lifted upward, the operator can move the paper, change the processing position, and realize an intermittent processing process.

[0028] Specifically, the device is rotatably connected to a follower plate 3 on one side of the support member 1 via a support shaft Ⅰ2, and the follower plate 3 can rotate relative to the support member 1 through the rotatable connection.

[0029] At the same time, the device is provided with a driven plate 11 on one side of the follower plate 3. Through holes 12 are respectively formed at the upper and lower ends of the driven plate 11 away from the support shaft, and the linkage rod 5 is inserted into the relatively upper through hole 12.

[0030] Therefore, the device can constrain the printing and dyeing roller 6 to be inserted into the relatively lower through hole 12, so that the linkage rod 5 can drive the printing and dyeing roller 6 to move up and down synchronously through the driven rod.

[0031] Therefore, the axial end of the constraint linkage rod 5 of the device is inserted into the positioning groove 4, and the position constraint effect of the positioning groove 4 on the linkage rod 5 is synchronously realized to constrain the motion trajectory of the printing and dyeing roller 6.

[0032] That is, by rotating the follower plate 3 so that the lower end surface of the positioning groove 4 is parallel to the horizontal plane, the printing roller 6 can make a left and right linear motion. When the rotating follower plate 3 makes the two ends of the positioning groove 4 not at the same height, the printing roller 6 tilts and the operator can move the paper.

[0033] Furthermore, the device constrains the number of follower plates 3 and driven plates 11 to be two, which can effectively avoid unilateral force imbalance of the linkage rod 5 by simultaneously constraining the positions of the two axial ends of the linkage rod 5 through the two follower plates 3.

[0034] Specifically, in order to control and realize the intermittent swinging process of the follower plate 3, the device is rotatably connected to a cam 7 at the near end of each of the two follower plates 3, and a corresponding limit shaft 8 is provided on the support member 1 for the cam 7 to constrain the cam 7 to abut against the limit shaft 8. Therefore, the height of the lower end surface of the follower plate 3 can be changed by rotating the cam 7 to change the distance between the central axis of the cam 7 and the limit shaft 8. The rotation process of the follower plate 3 can be realized in conjunction with the existence of the support shaft Ⅰ2.

[0035] Specifically, the cam 7 includes a main body 702 of a cylindrical structure, and an extension portion 701 is coaxially fixedly connected to the outer side of the main body 702 .

[0036] Therefore, by constraining the distance between the central axis of the cam 7 and the upper end surface of the limiting shaft 8 to be equal to the diameter of the main body 702 of the cam 7, the central axis of the cam 7 can be at the lowest height when the main body 702 of the cam 7 abuts against the limiting shaft 8. At this time, it is only necessary to ensure that the lower end surface of the corresponding positioning groove 4 is parallel to the horizontal plane, so that when the extension 701 of the cam 7 contacts the limiting shaft 8, the follower plate 3 can swing upward accordingly.

[0037] Furthermore, in order to reduce the friction caused by the relative movement between the cam 7 and the limit shaft 8, which leads to a reduction in the service life of the device, a bearing 9 is provided on the outer sleeve of the limit shaft 8 to constrain the bearing 9 to abut against the cam 7. The rolling connection between the bearing 9 and the cam 7 can fully reduce the friction resistance generated during the movement.

[0038] Furthermore, the angle of the fan-shaped structure corresponding to the extension 701 of the cam 7 is constrained by the device to be not less than 100° and not more than 150°, and the outer wall of the cam 7 has a smooth transition, which can fully ensure the stable duration of the follower plate 3 in the two forms. That is, this can ensure that when the main body 702 of the cam 7 abuts against the limit shaft 8, the linkage rod 5 can stably drive the printing and dyeing roller 6 to make left and right linear movements.

[0039] Furthermore, in order to obtain continuous intermittent roller printing and dyeing, the device is provided with a corresponding driving mechanism on one side of the cam 7 to drive the cam 7 to rotate continuously.

[0040] Specifically, the driving mechanism includes a support shaft II 10 which is coaxially fixedly connected to the cam 7 , and the support shaft II 10 is rotationally connected to the follower plate 3 .

[0041] A driven gear 13 is coaxially fixedly connected to the outer side of the support shaft II 10, and a drive motor 15 is provided on one side of the driven gear 13. When the output shaft of the drive motor 15 is transmission-connected to the driven gear 13, the drive motor 15 can drive the driven gear 13 and then drive the cam 7 to achieve continuous rotation.

[0042] Furthermore, in the device, a driving gear 14 is coaxially fixedly connected to the output shaft of the driving motor 15, and the driving gear 14 is constrained to be meshingly connected with the driven gear 13. By constraining the transmission ratio of the driving gear 14 to the driven gear 13 to be not equal to one, the driven gear 13 can rotate more slowly, and the rotation speed of the cam 7 driven by the driven gear 13 can meet the needs.

[0043] It should be noted that there are two follower plates 3 in the present device, and therefore, two sets of cams 7, limit shafts 8, and drive mechanisms with the same structure are provided in conjunction with the device.

[0044] Therefore, in practice, the two drive motors 15 can maintain the same movement trend through series connection and other related technologies, which can fully avoid the unbalanced force on one side of the printing and dyeing roller 6.

[0045] In actual use, the utility model:

[0046] First, the corresponding driving motor 15 is turned on, and at this time, the cam 7 rotates continuously (assuming that the cam 7 rotates clockwise at this time, and the main body 702 of the cam 7 abuts against the bearing 9);

[0047] Afterwards, as the cam 7 rotates continuously, driven by the driven plate 11, the printing roller 6 moves linearly from left to right;

[0048] Then, as the cam 7 rotates continuously until the extension 701 of the cam 7 contacts the bearing 9, the height of the central axis of the cam 7 is raised, and the follower plate 3 swings upward, and the printing roller 6 moves toward the support member 1 along the length direction of the positioning groove 4 for a short time and then moves in the opposite direction, and the printing roller 6 continues to rotate in the direction away from the support member 1;

[0049] Afterwards, as the cam 7 rotates continuously, the follower plate 3 swings upward to the top and then swings downward. At this time, the printing roller 6 continues to run in the direction away from the support member 1 along the length direction of the positioning groove 4;

[0050] Finally, as the cam 7 rotates, the main body 702 of the cam 7 is reset to a state of contact with the bearing 9, and at this time, the printing roller 6 moves linearly from left to right.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
