Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-4, the embodiment of the present invention discloses a leather embossing device, which comprises a frame 1, wherein a lower press roller 2 and an upper press roller 3 are rotatably arranged on the frame 1, and the leather passes between the lower press roller 2 and the upper press roller 3, and is embossed through the rolling of the lower press roller 2 and the upper press roller 3.

Referring to fig. 2, the upper press roll 3 can slide up and down and is disposed on the frame 1, a first chute 11 is disposed on the frame 1, a first slider 8 can slide up and down in the first chute 11, and the upper press roll 3 can rotatably penetrate through the first slider 8.

Referring to fig. 2, the frame 1 is rotatably provided with the swing frame 6, the right end of the swing frame 6 is rotatably hinged to the frame 1 along a horizontal axis, the swing frame 6 is provided with the counterweight 7 in a left-right sliding manner, the left end of the swing frame 6 can be abutted against the upper end face of the first slider 8, and the pressure of the swing frame 6 on the upper press roll 3 can be adjusted along with the left-right sliding of the counterweight 7, namely the pressure between the upper press roll 3 and the lower press roll 2 is changed.

In order to enable the first sliding block 8 to slide more stably in the first sliding groove 11 and conveniently place new leather between the lower compression roller 2 and the upper compression roller 3, the frame 1 is located in the first sliding groove 11 and fixedly provided with the stabilizer bar 9, the first sliding block 8 is provided with a through hole for the stabilizer bar 9 to pass through, the stabilizer bar 9 is sleeved with a spring 10, and two end faces of the spring 10 respectively abut against the bottom surface of the first sliding groove 11 and the lower end face of the first sliding block 8.

When the balancing weight 7 slides rightwards, the upward elastic force of the spring 10 is larger than the downward pressure applied to the first sliding block 8 by the swing frame 6, the upper press roller 3 is lifted upwards, and at the moment, leather can be placed between the lower press roller 2 and the upper press roller 3.

In order to avoid the stabilizer bar 9 conveniently, two lower pressing rods 26 are fixedly arranged on the lower end face of the swing frame 6, and the lower end face of each lower pressing rod 26 abuts against the upper end face of the first sliding block 8.

Referring to fig. 3, a sliding rod 15 is slidably disposed on the swing frame 6 in a left-right direction, the counterweight 7 is fixedly disposed on the sliding rod 15, a first threaded rod 12 and a second threaded rod 13 are rotatably disposed on the swing frame 6, central axes of the first threaded rod 12 and the second threaded rod 13 extend in the left-right direction, threaded sleeves 14 are disposed at two ends of the sliding rod 15, and the two threaded sleeves 14 are respectively sleeved on the first threaded rod 12 and the second threaded rod 13.

The first threaded rod 12 and the second threaded rod 13 are both fixedly provided with a second bevel gear 18, the swing frame 6 is rotatably provided with a rotating shaft 16, the rotating shaft 16 is fixedly provided with two first bevel gears 17, one first bevel gear 17 corresponds to one rotating shaft 16 for meshing transmission, and the swing frame 6 is provided with a motor 19 for driving the rotating shaft 16 to rotate.

When the motor 19 drives the rotating shaft 16 to rotate, the rotating shaft 16 drives the first threaded rod 12 and the second threaded rod 13 to simultaneously rotate, so that the counterweight block 7 is driven to slide left and right on the swing frame 6, and the mode drives the counterweight block 7 to slide more stably and is convenient to finely adjust.

In order to make the pressure between the upper press roller 3 and the lower press roller 2 more balanced, when avoiding the lower press roller 2 and the rolling of the upper press roller 3, because of the deformation of the lower press roller 2 and the upper press roller 3, the edge that leads to is inconsistent with the middle part rolling effect. A plurality of second pressing wheels 5 are arranged on the swinging frame 6, and the second pressing wheels 5 are matched with the upper pressing roller 3.
