Description

Technical Field

[0001] The utility model relates to the technical field of leather, in particular to a leather softening machine. Background Art

[0002] There are both chemical and physical methods of leather tanning. The physical method in the tanning process includes increasing the softness and strength of the leather through mechanical means such as stretching and rubbing. These physical treatments help make the leather more supple while maintaining its structural stability and durability.

[0003] Leather stretching usually uses a fixed-position wheel. The leather is first fed under the wheel and then pulled out. During the pulling process, the leather is stretched by the rotation of the wheel. Since the wheel is in a fixed position, after each set of stretching actions, the leather feeding position needs to be moved manually, and then manually fed and stretched using the wheel. That is, the three actions of position adjustment, feeding and stretching occur alternately, which makes the stretching process time-consuming.

[0004] The present invention provides a leather softening machine, which combines position adjustment and feeding actions into one time period and completes them synchronously through structural setting, so as to improve the overall efficiency. Utility Model Content

[0005] The utility model aims at least to solve the problem in the prior art that, due to the fixed position of the rotating wheel, the position adjustment action of the leather needs to be performed before feeding, which makes the stretching process time-consuming.

[0006] The present invention provides a leather softening machine, which is achieved by the following specific technical means: it comprises a base and a turntable rotatably mounted on the base, a mounting frame extending to the top of the turntable is fixed on the base, a horizontal frame is fixed on the mounting frame, a transverse seat is laterally slidably mounted on the horizontal frame, a vertical frame is vertically slidably mounted on the transverse seat, a wheel seat is fixed at the bottom end of the vertical frame, a rotating wheel rotates in the wheel seat, and the position change of the leather and the feeding action can be synchronously realized in coordination with the rotation of the turntable during the forward movement of the rotating wheel.

[0007] Preferred technical solution 1: A push-pull control mechanism is provided on the mounting frame, and the push-pull control mechanism is used to drive the transverse seat to move forward and backward on the transverse frame.

[0008] Preferred technical solution two: the push-pull control mechanism includes a swing arm hingedly mounted on a mounting frame at the top end, a slide groove being provided at the bottom end of the swing arm, a protrusion rotating on the rear wall of the transverse shift seat being inserted into the slide groove, and during the swinging process of the swing arm, the protrusion slides in the slide groove to drive the transverse shift seat to move forward and backward on the cross frame.

[0009] Preferred technical solution three: A fixed plate parallel to the horizontal frame is fixed on the horizontal frame, a parallelogram slide groove is opened on the fixed plate, and the protrusion three fixed on the vertical frame is inserted into the parallelogram slide groove and slides, and the protrusion three can only slide in a one-way cycle in the parallelogram slide groove.

[0010] Preferred technical solution four: The parallelogram slide groove is composed of a top groove, an inclined front groove, a bottom groove and an inclined rear groove connected in sequence, the top groove is parallel to the bottom groove, the inclined front groove is parallel to the inclined rear groove, the top end of the inclined front groove is connected to the top groove, and the bottom end is connected to the bottom groove.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. The structure is set to change the rotating wheel from a fixed position state to a variable position state, so that the position change and feeding action of the leather are completed in one time period, which greatly reduces the stretching tanning time;

[0013] 2. The parallelogram slide groove is used to enable the transverse shift seat to independently complete the lifting and lowering action of the rotating wheel during the forward and backward movement, thereby realizing the linkage control of the action. BRIEF DESCRIPTION OF THE DRAWINGS

After the transverse moving seat 5 moves to the front side, the vertical frame 6 moves down so that the rotating wheel 8 is close to the turntable 2 and contacts the leather placed on the turntable 2. During the backward movement of the transverse moving seat 5, the rotating wheel 8 maintains the contact state with the leather and rotates, and the rotating wheel 8 rotates to stretch the leather backward; during the forward movement of the rotating wheel 8, the rotation of the turntable 2 can synchronously realize the synchronous position change of the leather and the feeding action.

The push-pull control mechanism 9 includes a swing arm 91 hingedly mounted on the mounting frame 3 at the top, and a slide groove 911 is provided at the bottom of the swing arm 91. A protrusion 51 rotating on the rear wall of the transverse shift seat 5 is inserted into the slide groove 911, and during the swinging process of the swing arm 91, the protrusion 51 slides in the slide groove 911 to drive the transverse shift seat 5 to move forward and backward on the transverse frame 4. A motor 2 is fixed on the mounting frame 3, and a crank 92 is fixed on the output shaft of the motor 2, and a protrusion 2 93 is rotated at the end of the crank 92, and the protrusion 2 93 is inserted into the slide groove 2 912 provided in the middle part of the swing arm 91 and slides along the slide groove 2 912. The rotation of the motor 2 drives the crank 92 to rotate, and then the protrusion 2 93 slides in the slide groove 2 912 to achieve the technical effect of driving the swing arm 91 to swing back and forth.

[0023] See also Figure 2-Figure 4, leather softening machine, a fixed plate 10 parallel to the horizontal frame 4 is fixed on the horizontal frame 4, a parallelogram slide 11 is opened on the fixed plate 10, and the protrusion 3 61 fixed on the vertical frame 6 is inserted into the parallelogram slide 11 and slides. When the horizontal shift seat 5 moves forward, the protrusion 3 61 slides on the upper part of the parallelogram slide 11, so that the rotating wheel 8 is in a state of being lifted up and away from the leather. When the horizontal shift seat 5 moves backward, the protrusion 3 61 slides on the lower part of the parallelogram slide 11, so that the rotating wheel 8 is in a state of being pressed down and in contact with the leather;

[0024] The parallelogram slide 11 is composed of a top groove 111, an inclined front groove 112, a bottom groove 113 and an inclined rear groove 114 which are connected in sequence.

During the forward movement of the transverse shift seat 5, the projection 61 first slides along the top groove 111, then slides into the inclined front groove 112, and then enters the bottom groove 113 to complete the forward movement and downward pressing action of the rotating wheel 8. During the forward movement of the rotating wheel 8, the turntable 2 rotates to change the position of the leather; during the backward movement of the transverse shift seat 5, the projection 61 The three 61 first moves backward along the bottom groove 113, then slides into the inclined rear groove 114, and then enters the rear end of the top groove 111, completing the forward and backward movement and then lifting action of the rotating wheel 8. When moving backward, the rotating wheel 8 contacts the leather, and the depth of the bottom end of the inclined front groove 112 is less than the depth of the front end of the bottom groove 113. At the same time, the depth of the top end of the inclined rear groove 114 is less than the depth of the rear end of the top groove 111, so as to prevent the three 61 from moving back from the bottom groove 113 to the inclined front groove 112 when moving backward, or from the top groove 111 to the inclined rear groove 114 when moving forward, so as to ensure that the three 61 can only circulate in one direction in the parallelogram slide groove 11.
