Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, in particular to a detachable printing roller for printing wine boxes. Background Art

[0002] Wine boxes are one of the main packaging for wine. Wine boxes are usually printed with different patterns to improve recognition. Wine boxes are generally printed with patterns through a printing press, among which the transmission roller is the main part of the printing press. Different brands or different types of wine boxes need to be printed with different patterns or colors, so different transmission rollers are required for printing.

[0003] When printing different patterns on different printed materials, the existing technical means require frequent replacement of different transmission rollers. When replacing the transmission roller, it is necessary to remove multiple connecting parts at both ends of the transmission roller separately, and then replace the transmission roller as a whole or replace the printing roller on the transmission roller. Disassembly and replacement are inconvenient. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a detachable printing roller for printing wine boxes.

[0005] The technical solution of this utility model is as follows:

[0006] A detachable printing roller for wine box printing is arranged on a printing platform and comprises a transmission roller, and two ends of the transmission roller are rotatably supported on the printing platform by a fixed support plate and an adjustable support plate respectively;

[0007] The driving roller is provided with a first frustum body, a printing outer sleeve and a second frustum body coaxially arranged therewith in sequence, and both the first frustum body and the second frustum body are provided with an outer cylindrical clamping surface capable of contacting with the end of the printing outer sleeve, the first frustum body is arranged close to the fixed support plate, the second frustum body is slidably connected with one end of the driving roller away from the fixed support plate, the sliding direction is consistent with the direction of the axis of the driving roller, and the side of the second frustum body away from the first frustum body is rotatably connected with the adjustment support plate;

[0008] The adjusting support plate is slidably connected to the printing platform, the sliding direction is consistent with the axis direction of the driving roller, and is pressed against one side of the second truncated table body through a pressing piece.

[0009] The transmission roller is rotatably arranged on the printing platform, and one end of the transmission roller is rotatably connected to the fixed support plate through a bearing, and can pass through the fixed support plate to be connected to an external driving motor for rotation. The transmission roller is detachably provided with a printing outer sleeve for printing, and both ends of the printing outer sleeve are arranged between the first frustum body and the second frustum body, and are tightened on the outer cylindrical clamping surfaces of the first frustum body and the second frustum body through a tightening member. By adjusting the position of the support plate, the printing outer sleeve can be disassembled and tightened, and different types or patterns of printing outer sleeves can be quickly replaced to meet the surface printing requirements of different wine boxes.

[0010] Regarding the structure of the first frustum and the second frustum, both the first frustum and the second frustum have outer cylindrical clamping surfaces, the two outer cylindrical clamping surfaces are arranged opposite to each other, and the maximum outer cylindrical size of the outer cylindrical clamping surfaces is larger than the maximum outer diameter of the drive roller, which is convenient for clamping printing outer sleeves of different diameters to meet different printing needs.

[0011] In order to ensure that the printing outer sleeve is coaxially installed with the driving roller when it is sleeved on the driving roller, a plurality of guide members are provided on the outer circumferential surface of the driving roller, and the upper ends of the guide members can abut against the inner wall of the printing outer sleeve.

[0012] The sliding connection between the above-mentioned second frustum body and one end of the transmission roller is that both ends of the transmission roller are provided with a central axis coaxial therewith, and the second frustum body is plugged into the central axis along the axial direction and cannot rotate relative to each other, thereby preventing the second frustum body and the transmission roller from affecting the clamping of the printing outer sleeve due to relative rotation.

[0013] When the printing outer sleeve is sleeved on the driving roller, it may rotate, which will affect the guiding function of the guide member. For this reason, a sliding groove arranged opposite to the guide member is provided on the inner wall of the printing outer sleeve along its axial direction.

[0014] If the maximum outer circle dimension of the outer circle clamping surface is close to the inner diameter of the printing outer sleeve, it is inconvenient to install the printing outer sleeve, and the outer diameters of the first frustum and the second frustum increase from the inside to the outside, and the thickness decreases, resulting in that the outermost sides of the first frustum and the second frustum may be easily deformed when they are pressed against the printing outer sleeve. For this reason, the maximum outer circle dimension of the outer circle clamping surface is set to be 0.1-1 times larger than the inner diameter of the printing outer sleeve, and the sizes of the first frustum and the second frustum become larger to reduce deformation.

[0015] Regarding the connection relationship between the top tightening member and the printing platform and the adjusting support plate, at least two top tightening members are provided, the top tightening member passes through the printing platform along the axis direction of the driving roller and is rotatably connected to the adjusting support plate, and the top tightening member is threadedly connected to the printing platform.

[0016] In order to further ensure that the adjustment support plate is subjected to uniform force and can play a tightening role on the second truncated table body 7, a vertical plate located on one side of the adjustment support plate is provided on the printing platform, and two tightening members are distributed up and down, one tightening member passes through the adjustment support plate and presses against the upper part of the adjustment support plate, and the other tightening member passes through the printing platform and presses against the lower part of the adjustment support plate.

[0017] In order to facilitate the tightening member to tighten the printing outer sleeve onto the first truncated cone body through the second truncated cone body when tightening, an adjustment groove is opened on the printing platform, the bottom plate of the adjustment support plate is slidably connected in the adjustment groove, and the tightening member is located on the side of the adjustment support plate away from the fixed support plate.

[0018] The connection structure between the second frustum body and the adjustment support plate is that a connecting sleeve is provided on the side of the second frustum body away from the first frustum body, the connecting sleeve is coaxial with the transmission roller, and one end of the transmission roller is inserted into the connecting sleeve, and the connecting sleeve is rotatably connected to the adjustment support plate through a bearing.

[0019] The beneficial effects of the utility model are:

[0020] The printing outer sleeve is used to print patterns or colors on the surface of the wine box. The printing outer sleeve is detachably connected to the transmission roller. When the pattern or color needs to be changed, one end of the transmission roller is fixed on the fixed support plate, and the other end can be used to disassemble the second frustum. The printing outer sleeve can be quickly replaced without completely disassembling the transmission roller.

[0021] The second frustum body is rotatably connected to the adjusting support plate, and the tightening member is arranged on the outer side of the adjusting support plate. When tightened, the tightening member can tighten the printing outer sleeve onto the first frustum body through the second frustum body. When the printing outer sleeve is clamped, it will not affect the rotation of the printing outer sleeve following the transmission roller. BRIEF DESCRIPTION OF THE DRAWINGS

The plug-in method of the above-mentioned second frustum body 7 and one end of the transmission roller 2 is that both ends of the transmission roller 2 are provided with a center axis 21 coaxial therewith, which is used to be sleeved on the center axis 21. The outer cylindrical surface of the center axis 21 is provided with a slide bar 71 or a slide groove 23. The middle part of the second frustum body 7 has a center hole. In this embodiment, slide bars 71 are symmetrically arranged on the center hole. The length direction of the slide bar 71 is the same as the axial direction of the second frustum body 7. The outer cylindrical surface of the center axis 21 is symmetrically provided with a slide groove 23. The slide groove 23 is adapted to the slide bar 71. The slide bar 71 can be slidably connected in the slide groove 23, so that the second frustum body 7 can move along the axial direction of the transmission roller 2, which is convenient for disassembling the second frustum body 7, and realizing the disassembly and replacement of the printing outer sleeve 6 from one end where the second frustum body 7 is set.

[0035] A printing outer sleeve 6 for printing is detachably provided on the driving roller 2. Both ends of the printing outer sleeve 6 are arranged between the first frustum body 5 and the second frustum body 7, and are tightened on the outer cylindrical clamping surfaces 8 of the first frustum body 5 and the second frustum body 7 through a tightening member 9. By adjusting the position of the support plate 4, the printing outer sleeve 6 can be removed and tightened, and the printing outer sleeve 6 of different types or patterns can be quickly replaced to meet the surface printing requirements of different wine boxes.

[0036] According to the above specific structure, the beneficial effects that can be achieved by the utility model are as follows: the printing outer sleeve 6 is a tool used to contact the printing liquid of the printing equipment and print on the surface of the wine box. Different patterns or colors require different types of printing outer sleeves 6. In order to achieve rapid disassembly of the printing outer sleeve 6, the printing outer sleeve 6 is detachably connected to the drive roller 2. There is no need to completely disassemble the heavy drive roller 2, and the effect of quickly replacing the printing outer sleeve 6 can be achieved; and the second frustum body 7 is rotatably connected to the adjustment support plate 4, and the tightening member 9 is arranged on the outside of the adjustment support plate 4. When tightened, the tightening member 9 can tighten the printing outer sleeve 6 to the first frustum body 5 through the second frustum body 7. When the printing outer sleeve 6 is clamped, it does not affect the rotation of the printing outer sleeve 6 following the drive roller 2.

[0037] See also Figure 5 As shown, regarding the specific structure of the first frustum 5 and the second frustum 7, the first frustum 5 and the second frustum 7 are both frustum shaped structures, and a penetrating center hole is provided in the middle of the first frustum 5 and the second frustum 7, the first frustum 5 is fixedly connected to the center axis 21 at one end of the transmission roller 2 through the center hole, and the second frustum 7 is slidably connected to the center axis 21 at the other end of the transmission roller 2 through its center hole, and the outer cylindrical clamping surfaces 8 of the first frustum 5 and the second frustum 7 are arranged opposite to each other, and the maximum outer cylindrical size of the outer cylindrical clamping surface 8 is larger than the maximum outer diameter of the transmission roller 2, which is convenient for clamping printing outer sleeves 6 of different diameters to meet different printing requirements.

[0038] See also Figure 4 As shown, the printing outer sleeve 6 is sleeved on the driving roller 2, so the inner diameter is larger than the outer diameter of the driving roller 2. In order to make the printing outer sleeve 6 coaxially installed with the driving roller 2 when sleeved on the driving roller 2, a plurality of guide members 11 are provided on the outer circumferential surface of the driving roller 2. The guide members 11 are cylindrical bodies, and the upper end faces are arc-shaped surfaces. The upper ends of the guide members 11 can reach the inner wall of the printing outer sleeve 6. In this embodiment, at least three groups of guide members 11 are provided, and two guide members 11 symmetrically arranged relative to the axis of the driving roller 2 are one group. The three groups of guide members 11 are distributed at equal intervals along the axis direction of the driving roller 2, so as to facilitate the guiding support of the entire printing outer sleeve 6 and facilitate the printing outer sleeve 6 to rotate stably following the driving roller 2.

[0039] When the printing outer sleeve 6 is mounted on the driving roller 2 , it may rotate, which will affect the guiding function of the guide member. For this reason, a sliding groove 61 arranged opposite to the guide member 11 is opened on the inner wall of the printing outer sleeve 6 along its axial direction, and the upper end of the guide member 12 is slidably connected in the sliding groove 61 .

[0040] The outer cylindrical clamping surface 8 is in direct contact with the end of the inner wall of the printing outer sleeve 6.
