Description

Technical Field

[0001] The utility model belongs to the technical field of leather inspection machines, in particular to an improved desktop leather inspection machine. Background Art

[0002] The leather inspection machine is used to stretch the surface of leather, so that users can observe whether there are scars, nodules, holes and other surface quality problems. The clamping and stretching mechanism of the leather inspection machine replaces the traditional manual inspection method and improves the efficiency of leather inspection. At present, the devices used to clamp the edge of leather in the leather inspection machine mostly adopt the clamping roller type or the downward pressure type. These two methods have the following disadvantages:

[0003] 1. When a clamping roller mechanism is used as a clamping device, in order to save installation space, the support plate for supporting the leather is usually made into an inclined structure, such as the prior art with announcement number (CN204832062U). When the leather needs to be inspected, it is quite laborious to put the leather on the inclined support plate. If the leather is not pre-clamped, the inclined leather is easy to slide off, which is not conducive to convenient loading for users.

[0004] 2. When a downward pressing mechanism is used as a clamping device, the leather is placed on the support plate during use, and then the downward pressing mechanism is lowered to press the leather. For example, in the prior art with announcement number (CN211005446U), the initial state of the downward pressing mechanism must be set to a height higher than the mounting frame of the leather inspection machine, that is, the downward pressing mechanism is at a height of a part of the protruding mounting frame to achieve the downward pressing function. This setting takes up space. In the initial state, the support plate and the downward pressing mechanism form a stepped structure of varying heights, which cannot meet the demand for convenient loading. For larger pieces of leather, it is not convenient for users to easily lay them on the support plate.

[0005] Therefore, there is an urgent need for a leather inspection machine that is convenient for loading and clamping leather. Utility Model Content

The clamping device 2 includes a first rectangular frame 201. The four corners of the first rectangular frame 201 are respectively connected to the output ends of four first lifting drive mechanisms 202. The first rectangular frame The two mutually parallel first side strips 203 of the frame 201 are respectively located below the two mutually parallel second side strips 103 of the upper rectangular frame 101, and the first side strips 203 are respectively parallel to the corresponding second side strips 103 above them, and the length of the first side strip 203 is less than the length of the second side strip 103. The lifting device 3 includes a second rectangular frame 301, and the four corners of the second rectangular frame 301 are respectively connected to the output end of the second lifting drive mechanism 302, and an arc-shaped top plate 4 is installed on the second rectangular frame 301.

[0028] The clamping device 2 uses the first rectangular frame 201 and the upper rectangular frame 101 of the mounting frame 1 to form a clamp for clamping the edge of the leather, and controls the first lifting drive mechanism 202 to push the first rectangular frame 201 up to the bottom of the upper rectangular frame 101, so that the first side strip 203 and the second side strip 103 are pressed against each other.

[0029] Furthermore, a first soft rubber strip 5 is provided on one side of the first side strip 203 close to the second side strip 103 , and a second soft rubber strip 6 is provided on one side of the second side strip 103 close to the first side strip 203 . This arrangement plays a role in clamping the leather and preventing damage to the leather.

[0030] Further, the first lifting drive mechanism 202 may be a linear cylinder or a hydraulic cylinder, and the second lifting drive mechanism 302 may be a linear cylinder or a hydraulic cylinder. In this embodiment, the first lifting drive mechanism 202 is a first linear cylinder, and the output rods of the four linear cylinders are respectively connected to the four corners of the first rectangular frame 201, and the first rectangular frame 201 is smoothly raised or lowered by controlling the four first linear cylinders to rise or fall synchronously. The second lifting drive mechanism 302 is a second linear cylinder, and the output rods of the four second linear cylinders are respectively connected to the four corners of the second rectangular frame 301, and the second rectangular frame 301 is smoothly raised or lowered by controlling the four second linear cylinders to rise or fall synchronously.

[0031] Furthermore, a sponge or a soft rubber pad is provided on a side of the arc-shaped top plate 4 away from the second rectangular frame 301 , and this setting is used to prevent the leather back from being damaged when the arc-shaped top plate 4 rises to tighten the leather.

[0032] Furthermore, a control box 7 is installed between the upper rectangular frame 101 and the lower rectangular frame 102 , and a control module is arranged in the control box 7 .

[0036] When in use, the leather to be inspected is placed in the arc-shaped top plate 4, and the two opposite edges of the leather are placed between the first edge 203 and the second edge 103 respectively. The first lifting drive mechanism 202 is started through the control panel or the remote control. The first lifting drive mechanism 202 pushes the first rectangular frame 201 to rise in the direction of the upper rectangular frame 101, so that the first side strip 203 and the second side strip 103 are pressed against each other, thereby clamping the two sides of the leather; at this time, the second lifting drive mechanism 302 is started through the control panel or the remote control.
