Technical Field

[0001] The utility model relates to the technical field of trademark paper processing, and more specifically, to a trademark paper steel printing roller and a device. Background Art

[0002] During the transportation of small box trademark paper, there is a pair of steel printing rollers in the trademark paper transportation channel. When the small box trademark paper is transported horizontally, this pair of steel printing rollers presses a string of production codes at the bottom of the small box packaging for product traceability.

[0003] The outer edge of the existing steel stamp roller has a cam arc, and the steel stamp is installed and fixed in the middle position of the cam stroke. The cam and the wheel body are integrally formed. Its function is to cooperate with the steel roller below to transport the small box trademark paper forward through the action of friction. At the same time, when it rotates to the steel stamp position, the steel stamp contacts the small box trademark paper to imprint the production code. Since the cam and the wheel body are integrally formed, the position between the cam and the steel stamp cannot be adjusted, resulting in the steel stamp roller being unable to adapt to the steel stamp requirements of the small box trademark paper in other positions.

[0004] The prior art Chinese patent CN201920879320.7 discloses a steel roller for printing trademark paper, comprising a center piece, both sides of which are provided with limit plates, and a center hole is opened on one side of the center piece and the limit plate, a first fixing hole is opened on one side of the center piece, and the first fixing hole is connected to the center hole, a mounting hole is opened on one side of the limit plate, and the mounting hole is located directly below the center hole, the diameter of the mounting hole is smaller than the diameter of the center hole, a limit fixing surface is opened on one side of the center piece, and a flattening wheel is provided at the edge of the limit plate. The utility model can facilitate the steel stamp shaft and the steel stamp, facilitate the work of printing and stamping trademark paper, is easy to install, can facilitate the installation of the steel stamp operation, and ensure that the digital code of the steel stamp will not be confused, improve the working effect of the device, can transport the trademark paper during the rotation of the center piece, and can assist in flattening the paper to prevent the unevenness of the trademark paper from affecting the effect of printing and stamping. However, the flattening wheel (cam) and the center piece (wheel body) of this technical solution are fixed structures, and the printing position cannot be adjusted. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiency of the existing technology that the position of the steel printing roller cam cannot be adjusted, and to provide a trademark paper steel printing roller and device, which can meet the printing pressure requirements of different positions of the trademark paper and has strong compatibility.

[0006] In order to achieve the above-mentioned purpose, the technical solution provides a trademark paper steel stamp roller, including a steel stamp assembly, a steel stamp and two conveying cams, the two conveying cams are respectively rotatably connected to the two ends of the steel stamp assembly, each conveying cam is coaxially arranged with the steel stamp assembly and one side of each conveying cam protrudes from one side of the steel stamp assembly, the two ends of the steel stamp assembly are respectively detachably connected with a number of fasteners for fixing each conveying cam, the steel stamp is connected to the steel stamp assembly and corresponds to the protruding side position of each conveying cam.

[0007] In this technical solution, the steel stamp assembly rotates and drives the protruding side of the two conveying cams to intermittently convey the trademark paper. The steel stamp corresponds to the position of the protruding side of each conveying cam. When the steel stamp contacts the trademark paper, it prints and presses. When the position of the steel stamp needs to be adjusted, the fasteners are loosened and the two conveying cams are rotated at the same time to adjust their relative positions with the steel stamp. Then the fasteners are tightened to complete the adjustment of the steel stamp position. This can meet the steel stamp requirements at different positions of the trademark paper, and the adjustment process is simple and convenient.

[0008] As a preferred solution, in order to stably convey the trademark paper, the two conveying cams are symmetrically arranged about the steel printing assembly, and the protruding sides of the two conveying cams correspond to ensure the horizontal conveyance of the trademark paper.

[0009] As a preferred solution, the steel stamp assembly includes a connecting shaft and two turntables respectively fixed at both ends of the connecting shaft. Each of the conveying cams is respectively connected to the end face of each turntable away from the connecting shaft. The conveying cam is rotatably connected to the turntable and the conveying cam and the turntable are coaxially arranged. The position of the printing pressure can be adjusted by rotating and adjusting the relative position of the conveying cam and the turntable.

[0010] As a preferred solution, in order to convey the trademark paper, each of the conveying cams has an arc-shaped protrusion protruding from the edge of the turntable part, and the steel stamp corresponds to the position of each protrusion. When the steel stamp roller rotates, the protrusion conveys the trademark paper while the steel stamp is pressed on the trademark paper at the same time. The trademark paper is divided into multiple sheets, and the arc length of the protrusion corresponds to the length of each sheet of trademark paper. Since the protrusion protrudes from the edge of the turntable part, when the steel stamp roller rotates to the point where the protrusion no longer contacts the trademark paper, the trademark paper is not conveyed, thereby realizing intermittent conveying of the trademark paper.

[0011] As a preferred solution, in order to ensure the coaxiality of the conveying cam and the turntable, one side of each conveying cam is recessed inward to form a receiving groove adapted to the shape of each turntable, and each turntable is installed in each receiving groove so that each protrusion covers part of the side surface of each turntable.

[0012] As a preferred solution, in order to realize the rotation adjustment of the conveying cam, three arc-shaped waist holes are respectively provided on the end face of each conveying cam and are arranged at intervals along its rotation direction. The fasteners are screws adapted to the waist holes. The three screws pass through the waist holes respectively and are fixed on the end face of the turntable. After loosening the screws, the conveying cam can be rotated under the limit of the waist holes, and the screws slide relatively in the waist holes. After the adjustment is completed, the screws are tightened.

[0013] As a preferred solution, in order to further limit the screws to ensure the coaxiality of the conveying cam and the turntable, each cam is provided with three limiting grooves corresponding to the positions of each waist hole, each waist hole is respectively provided at the bottom of each limiting groove, and the head of each screw is placed in the limiting groove.

[0014] As a preferred solution, in order to install the screws, each turntable is embedded with three internal thread plugs that are compatible with each screw, the screw rod of the screw is threadedly connected to the internal thread plug, and the end face of the internal thread plug is flush with the end face of the turntable.

[0015] As a preferred solution, the two ends of the steel stamp are respectively connected to the end faces of the two turntables close to the connecting shaft, and one end of the steel stamp protrudes from one side of each raised portion. Since the raised portion is used to convey the trademark paper, the steel stamp is set at the corresponding position of the raised portion, and the relative position of the raised portion and the steel stamp is adjusted by adjusting the position of the conveying cam to achieve adjustment of the printing pressure position.

[0016] To achieve the above-mentioned purpose, a trademark paper steel stamping device of the present technical solution includes the above-mentioned trademark paper steel stamping roller, and also includes a front roller, a support seat and two contrast rollers. The support seat is provided with two relative driving shafts and two driven shafts. The front roller and the steel stamping assembly are respectively connected to the two driving shafts, and the two contrast rollers are respectively connected to the two driven shafts.

[0017] In this technical solution, the two driving shafts have the same rotation direction and speed. The front roller and the opposite contrast roller cooperate to intermittently transport the trademark paper one by one, and the steel printing roller and the opposite contrast roller cooperate to intermittently transport the trademark paper while printing and pressing at the corresponding position.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The stamp assembly of the trademark paper stamp roller of the utility model drives the conveying cam to intermittently convey the trademark paper and stamps the stamp during the conveying process. By adjusting the relative position of the conveying cam and the stamp, the stamping position can be adjusted to meet the requirements of various stamping positions of trademark paper.

[0020] 2. The conveying cam and the steel stamp assembly of the utility model are separated structures. After the position of the conveying cam is adjusted, it is fixed by fasteners, which makes the adjustment convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment provides a trademark paper steel stamp roller, including a steel stamp assembly 1, a steel stamp 2 and two conveying cams 3, the two conveying cams 3 are respectively rotatably connected to the two ends of the steel stamp assembly 1, each conveying cam 3 is coaxially arranged with the steel stamp assembly 1 and one side of each conveying cam 3 protrudes from one side of the steel stamp assembly 1, and the two ends of the steel stamp assembly 1 are respectively detachably connected with a number of fasteners for fixing each conveying cam 3, the steel stamp 2 is connected to the steel stamp assembly 1 and corresponds to the protruding side position of each conveying cam 3.

[0033] In this embodiment, the steel stamp assembly 1 and the two conveying cams 3 are split structures. The steel stamp assembly 1 serves as the main support of the steel stamp roller and can transmit torque. The steel stamp 2 is fixed on the steel stamp assembly 1. The surface of the steel stamp 2 has raised characters. When the steel stamp 2 presses over the trademark paper 9, a recessed steel stamp will be left on the trademark paper 9. The steel stamp assembly 1 does not contact the trademark paper 9, that is, the steel stamp assembly 1 directly conveys the trademark paper 9, but contacts the trademark paper 9 through the protruding parts of the conveying cams 3 on both sides for conveying. The part of the conveying cam 3 only protrudes from one side of the steel stamp assembly 1, so the conveying mode of the conveying cam 3 for the trademark paper 9 is intermittent conveying. After loosening the fasteners on the steel stamp assembly 2, the conveying cams 3 on both sides of the steel stamp assembly 1 are rotated and adjusted at the same time to adjust the relative position of the conveying cam 3 and the steel stamp 2, thereby realizing the adjustment of the printing pressure position of the trademark paper 9.

[0034] Specifically, such as Figure 1 、 2 As shown, the two conveying cams 3 are symmetrically arranged with respect to the steel stamping assembly 1 .

[0035] In this embodiment, in order to transport the trademark paper 9 horizontally, the two transport cams 3 must be symmetrically arranged with respect to the steel stamp assembly 1 after being fixed by fasteners.

[0036] Specifically, such as Figure 4 As shown, the steel stamp assembly 1 includes a connecting shaft 11 and two turntables 12 respectively fixed at both ends of the connecting shaft 11 , and each of the conveying cams 3 is respectively connected to the end surface of each of the turntables 12 away from the connecting shaft 11 .

[0037] In this embodiment, the two turntables 12 are disc structures, which are integrated with the connecting shaft 11. The connecting shaft 11 is used to connect to the power output end of the conveying device to transmit torque.

[0038] Specifically, each of the conveying cams 3 has an arc-shaped protrusion 31 protruding from the edge of the turntable 12 , and the steel stamp 2 corresponds to the position of each of the protrusions 31 .

[0039] In this embodiment, if Figure 5 As shown, the raised portion 31 can be obtained by milling the conveying cam 3, which can ensure the overall structural strength. The raised portion 31 directly contacts the trademark paper 9 to achieve intermittent conveying of the trademark paper 9. The arc length of the raised portion 31 is equal to the length of a piece of trademark paper 9, so that when the steel printing roller rotates one circle, it can just convey a piece of trademark paper 9 and complete the printing work of the trademark paper 9.

[0040] Specifically, one side of each conveying cam 3 is recessed inward to form a receiving groove 32 adapted to the shape of each turntable 12 , and each turntable 12 is installed in each receiving groove 32 so that each protrusion 31 covers part of the side surface of each turntable 12 .

[0041] In this embodiment, if Figure 1 、 5 As shown, the width of the capacity groove 32 is equal to the width of the turntable 12, so that the protrusion 31 covers part of the side surface of the turntable 12. The design of this structure allows the force borne by the protrusion 31 during the conveying process to be transmitted to the turntable 12, thereby avoiding deformation of the protrusion 31 due to long-term work.

[0042] Specifically, each conveying cam 3 has three arc-shaped waist holes 33 spaced apart along its rotation direction on its end face, and the fasteners are screws 4 adapted to the waist holes 33 . The three screws 4 pass through the waist holes 33 and are fixed to the end face of the turntable 12 .

[0043] In this embodiment, if Figure 1 、 2 As shown, the conveying cam 3 on each side is fixed by three screws 4 to ensure that the conveying cam 3 does not move during operation, thereby ensuring the accuracy of the printing position.

[0044] Specifically, such as Figure 3 As shown, each cam is provided with three limiting grooves 34 corresponding to the positions of each waist hole 33, each waist hole 33 is respectively provided at the bottom of each limiting groove 34, and the head of each screw 4 is placed in the limiting groove 34.

[0045] In this embodiment, the head width of the screw 4 is adapted to the slot width of the limiting slot 34. During the process of loosening the screw 4, it is sufficient to ensure that the conveying cam 3 can rotate, and the head of the screw 4 does not need to be separated from the limiting slot 34. During the adjustment of the conveying cam 3, the head of the screw 4 moves relative to the inner walls on both sides of the limiting slot 34. This process can ensure the coaxiality of the conveying cam 3 and the steel stamp assembly 1.

[0046] Specifically, three inner thread plugs 5 adapted to the screws 4 are respectively embedded on each of the turntables 12 , and the screw rods of the screws 4 are threadedly connected to the inner thread plugs 5 .

[0047] In this embodiment, the female thread plug 5 is used to install the screw 4 .

[0048] Specifically, such as Figure 1 、 2 As shown, both ends of the steel stamp 2 are respectively connected to the end surfaces of the two turntables 12 close to the connecting shaft 11 , and one end of the steel stamp 2 protrudes from one side of each of the protruding portions 31 .

[0049] In this embodiment, the raised portion 31 completes the printing work on the trademark paper 9 while conveying the trademark paper 9 .

[0050] Example 2:

[0051] This embodiment is similar to embodiment 1, except that, in this embodiment, the steel stamp 2 can be a rotating body structure having an axis, and is provided with a plurality of centrally symmetrical surfaces relative to the axis, and each surface is provided with different raised characters, so that the steel stamp 2 can print different characters. The steel stamp 2 can be rotatably installed on the end faces of the two turntables 12 close to the connecting shaft 11, and the switching of the printed characters can be achieved by rotating the steel stamp 2.

[0052] Example 3:

[0053] like Figure 6 As shown, this embodiment provides a trademark paper steel stamping device, including the above-mentioned trademark paper steel stamping roller, and also includes a front roller 7, a support seat 6 and two contrast rollers 8, the support seat 6 is provided with two opposite driving shafts 61 and two driven shafts 62, the front roller 7 and the steel stamping assembly 1 are respectively connected to the two driving shafts 61, and the two contrast rollers 8 are respectively connected to the two driven shafts 62.

[0054] In this embodiment, the steel stamp assembly 1 , the front roller 7 and the two contrast rollers 8 are all provided with mounting holes for mounting the driving shaft 61 or the driven shaft 62 .
