Technical Field

[0002] An embossing machine is a device used to emboss or texture the surface of a material. Usually, the stacked pad, paper, and die cutter are placed between two rollers, and the rollers apply pressure to the surface of the material and the rotation of the rollers drives the pad, paper, and die cutter to move, eventually forming a variety of patterns, designs, or textures on the paper, giving the material a richer decorative effect.

[0003] At present, in order to adapt to the different types and thicknesses of pads and cutting dies, as well as to control the depth of the cutting pattern, the embossing machine mostly adopts a fixed roller spacing design, and the versatility of the embossing machine is improved by selecting pads of different thicknesses. This type of embossing machine is more troublesome to operate. Recently, some embossing machines that adjust the spacing between the upper and lower rollers have appeared on the market. The two rollers on the embossing machine are mainly driven to roll by the transmission between the gears. When the spacing between the two rollers changes, the center distance of the gears on the two rollers changes, causing the position of the meshing point of the gears to change, resulting in poor gear meshing, causing noise, vibration, tooth surface wear and other problems, and even failure to transmit, affecting the normal use and life of the embossing machine. Therefore, it is necessary to provide an embossing machine with adjustable relative spacing between rollers that does not affect the smooth transmission of the gears. Utility Model Content

[0026] See also Figure 1 As shown, an embossing machine includes a main frame 1, an upper roller 2, a lower roller 3 and a power device 4 for driving the upper roller 2 and the lower roller 3 to rotate.

[0027] Specifically, a first cavity 101 is provided on both sides of the main frame 1, and a fixing seat 5 is provided in the first cavity 101, which can slide in the vertical direction along the side wall of the first cavity 101. Both ends of the upper roller 2 are rotatably mounted on the fixing seat 5, and one end of the upper roller 2 is connected to a first rotating gear 9 through a slider coupling 8. When the fixing seat 5 slides in the vertical direction along the side wall of the first cavity 101, the upper roller 2 follows the fixing seat 5 and slides up and down in the vertical direction, so that the position of the upper roller 2 moves in the vertical direction and deviates from the center of the first rotating gear 9 through the slider coupling 8.

[0028] A plurality of return springs 10 are provided between the fixing seat 5 and the bottom of the first cavity 101, and the two ends of the return spring 10 are respectively in contact with the bottom of the fixing seat 5 and the bottom of the first cavity 101. By applying different forces to the top of the fixing seat 5 or limiting the position of the fixing seat 5, the return spring 10 can be compressed or extended, so that the fixing seat 5 can move in the vertical direction along the side wall of the first cavity 101.

[0029] Preferably, a plurality of spring tubes 502 are provided at the bottom of the fixing seat 5 , and the return spring 10 is installed in the spring tube 502 and abuts against the bottom of the first cavity 101 .

[0030] Preferably, a groove is provided on both sides of the fixing seat 5, and the side wall of the first cavity is provided with a boss slidably matched with the groove. The fixing seat 5 cooperates with the boss through the groove, so as to be slidably connected in the first cavity, and a plurality of spring tubes 502 are provided at its bottom. The reset spring 10 is installed in the spring tube 502 and abuts against the bottom of the first cavity 101.

[0031] A first circular hole 503 is provided in the middle of the fixed seat 5, and a first bearing 6 is provided in the first circular hole 503, and both ends of the upper roller 2 are respectively mounted on the first bearing 6; a baffle 11 is provided on the main frame 1, and a first slide groove (not marked in the figure) is formed between the baffle 11 and the fixed seat 5, and a top plate 12 is provided in the first slide groove, and the top plate 12 includes a top plate body 1201 and a slope 1202 distributed at both ends of the top plate body 1201; the slope 1202 is respectively in contact with an inclined surface 501 on the top of the fixed seat 5 on the same side; a driving device 13 is provided on the top plate 12, and the driving device 13 is used to drive the top plate 12 to move horizontally in the first slide groove. In this embodiment, the slope 1202 has the same slope as the slope 501 , the slope 1202 decreases in height from left to right, and the slope 501 increases in height from left to right. The slope 1202 is arranged opposite to the slope 501 and is in close contact with it.

[0032] The driving device 13 includes a rotating knob 1301 rotatably mounted on the baffle 11 and a third rotating gear 1302 connected to the rotating knob 1301. A second cavity 1203 is provided on the top plate body 1201. A gear 1204 is provided on one side of the second cavity 1203 in the horizontal direction. The third rotating gear 1302 is meshed and connected with the gear 1204, and drives the top plate 12 to slide in the horizontal direction in the first slide groove through the rotation of the rotating knob 1301. Preferably, a plurality of scales 1101 are provided on the baffle 11 along the circumference of the rotating knob, and the scales 1101 correspond to the distance that the top plate 11 slides in the first slide groove in the horizontal direction. By rotating the corresponding angle selection scale 1101 through the rotary knob 1301, the sliding distance of the top plate 11 in the first slide groove in the horizontal direction can be accurately adjusted, so that the upper roller 2 can be controlled to move a certain distance in the vertical direction, and the spacing between the upper roller 2 and the lower roller 3 can be precisely adjusted. The pressure received by the embossing die can be adjusted by adjusting the spacing, and the depth of the embossing pattern can be controlled to achieve precise embossing operation.

[0033] When the rotating knob 1301 is rotated to drive the third rotating gear 1302 to rotate, the gear teeth 1204 of the third rotating gear meshing with each other drive the top plate 12 to move to the left in the first slide slot in the horizontal direction, so that the slope 1202 moves along the left side of the inclined surface 501, and the height of the part where the slope 1202 abuts against the inclined surface 501 becomes smaller, so that the reset spring 10 is extended, and then the fixed seat 5 slides upward in the vertical direction, and the upper roller 2 follows the fixed seat 5 to slide upward, and deviates upward from the center of the first rotating gear 9 through the slider coupling 8. When the top plate 12 moves to the right in the first slide slot in the horizontal direction, the slope 1202 moves along the right side of the inclined surface 501, and the height of the part where the slope 1202 abuts against the inclined surface 501 becomes larger, so that the reset spring 10 is compressed, and then the fixed seat 5 slides downward in the vertical direction, and the upper roller 2 follows the fixed seat 5 to slide downward, and deviates downward from the center of the first rotating gear 9 through the slider coupling 8.

[0034] The slider coupling 8 includes a left half coupling 801, a right half coupling 802 and a slider 803 slidably arranged between the left half coupling 801 and the right half coupling 802. The left half coupling 801 is fixedly connected to the rotating shaft 201 of the upper roller 2, and the right half coupling 802 is fixedly connected to the first rotating gear 9 through a transmission shaft 15. The slider 803 slides on the left half coupling 801 or the right half coupling 802 as the upper roller 2 slides in the vertical direction.

[0035] The end surfaces of the left half coupling 801 and the right half coupling 802 are both provided with arc-shaped shock-absorbing gaskets (not shown in the figure). The arc-shaped shock-absorbing gaskets are made of elastic material and can absorb and buffer the vibration and impact force generated when the coupling is working, thereby protecting the normal operation of the coupling and reducing the noise level.

[0036] The left half coupling 801 is provided with a second slide groove 8011 which cooperates with the slider 803, and the slider 803 is provided with a third slide groove 8031 ​​which cooperates with the right half coupling 802; when the rotating shaft 201 rotates, the slider coupling 8 transmits torque, and the slider 803 rotates with the rotating shaft 201 and slides in the first slide groove 8011 or the third slide groove 8031. The sliding and rotation of the slider are carried out simultaneously, and the torque is transmitted from a rotating shaft 201 to the transmission shaft 15 through friction.

[0037] The walls of the second slide groove 8011 and the third slide groove 8031 ​​are both provided with oil storage grooves (not shown in the figure), and lubricating grease is provided in the oil storage grooves. By providing the oil storage grooves to store a certain amount of lubricating grease and keeping it on the contact surface of the slider coupling 8 through an oil seal or other structure, the friction heat and friction loss generated when the slider 803 slides relative to the left half coupling 801 and the right half coupling 802 can be reduced, and the service life of the slider coupling 8 can be extended. At the same time, the oil storage groove can also play the role of cooling the slider 803 and reducing shock, ensuring the normal operation of the slider coupling 8.

[0038] The lower roller 3 is rotatably mounted on both sides of the main frame 1 below the first cavity 101, and one end of the lower roller 3 is fixedly connected to a second rotating gear 14; the first rotating gear 9 is meshed and connected with the second rotating gear 14; a transmission gear shaft 15 is also rotatably mounted on the main frame 1 on one side of the first rotating gear 9, and the transmission gear shaft 15 is meshed and connected with the second rotating gear 14 and connected with the power device 4. The power device 4 provides power to rotate the transmission gear shaft 15, driving the first rotating gear 9 meshed with the transmission gear shaft and the second rotating gear 14 meshed with the first rotating gear 9 to rotate, thereby driving the upper roller 2 and the lower roller 3 to rotate in the same direction.

[0039] Wherein, second circular holes 102 are provided on both sides of the main frame 1 below the first cavity 101 , second bearings 7 are provided in the second circular holes 102 , and both ends of the lower roller 3 are respectively mounted on the second bearings 7 .

[0040] The power device 4 is a driving motor (not shown in the figure) or a rocking handle 41 .

[0041] The working principle of the embossing machine provided by the utility model is as follows: when the user operates, first according to the demand for the spacing between the upper roller 2 and the lower roller 3, the rotary knob 1301 is turned to drive the top plate 12 to slide in the first slide groove in the horizontal direction. When it is necessary to increase the spacing between the upper roller 2 and the lower roller 3, the rotary knob 1301 is turned to drive the top plate 12 to move to the left along the horizontal direction, at this time, the reset spring 10 is stretched, so that the fixed seat 5 rises in the vertical direction, driving the upper roller 2 to rise in the vertical direction, so that the spacing between the upper roller 2 and the lower roller 3 is increased; when it is necessary to reduce the spacing between the upper roller 2 and the lower roller 3, the rotary knob 1301 is turned to drive the top plate 12 to move to the right in the horizontal direction, at this time, the reset spring 10 is compressed, so that the fixed seat 5 descends in the vertical direction, driving the upper roller 2 to move first in the vertical direction, so that the spacing between the upper roller 2 and the lower roller 3 is reduced.

[0042] At the same time, the slider 803 slides on the left half coupling 801 or the right half coupling 802 as the upper roller 2 slides up and down in the vertical direction, so that the upper roller 2 deviates upward or downward from the center of the first rotating gear 9 while moving upward or downward in the vertical direction. At this time, the center distance between the first rotating gear 9 and the second rotating gear 14 remains unchanged, and a normal meshing state is maintained; after the upper roller 2 and the lower roller 3 are adjusted to a certain distance according to the use requirements, the transmission gear shaft 15 is driven to rotate by the power device 4, thereby driving the first rotating gear 9 meshed with the rotating gear shaft 15 to rotate, and then driving the second rotating gear 14 meshed with the first rotating gear 9 to rotate, thereby realizing the gear transmission between the first rotating gear 9, the second rotating gear 14 and the transmission gear shaft 15, driving the upper roller 2 and the upper roller 3 to roll, and realizing embossing and transmission operations.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which should all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
