[0008] Preferably, a groove is provided inside the right end of the processing table and is located directly below the guide roller, and both ends of the auxiliary roller are rotatably mounted on inner bearings of the groove through bearings.

[0009] Preferably, both the front and rear ends of the guide roller are fixedly connected with a first gear, and the first gear is transmission-connected to the polishing assembly.

[0010] Preferably, a fixing bracket is fixedly provided on the rear end outer wall of the mounting bracket, a driving motor is fixedly installed on the inner wall of the fixing bracket, and an output end of the driving motor is fixedly connected to the center of the first gear located at the rear.

[0011] Preferably, the polishing assembly includes a polishing roller, a second gear, a connecting rod, a third gear and a pull rod. The polishing roller is located on the left side of the guide roller and the two are linked. The front and rear ends of the polishing roller are fixedly connected to the second gear. The outer sides of the front and rear ends of the polishing roller are respectively connected to two connecting rods with bearings. The middle part of the two connecting rods facing away from each other is equipped with a third gear with bearings. The upper ends of the two connecting rods are hinged to the pull rod, and the ends of the two pull rods away from the connecting rod are hinged to the two outer tubes respectively.

[0015] Preferably, the polishing roller and the guide roller have the same rotation direction, and the rotation speed of the polishing roller is greater than the rotation speed of the guide roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the solution of the present invention, two electric telescopic rods are used to control the synchronous vertical downward movement of the cross bar, outer tube, inner rod, guide assembly and polishing assembly.

DETAILED DESCRIPTION

[0027] The embodiments described below are only a portion of the embodiments of the present invention and do not represent all embodiments consistent with the present invention. The exemplary embodiments are described below in conjunction with the accompanying drawings:

[0028] like Figure 1-5 As shown in Figure 1, the utility model is a polishing machine for leather manufacturing, which includes a processing table 1 and a polishing assembly 9. A support frame 2 is fixedly provided on the upper right side of the processing table 1. Two electric telescopic rods 3 are symmetrically fixedly installed on the top of the support frame 2. A cross bar 4 is provided between the telescopic ends of the two electric telescopic rods 3 for fixed connection. Two outer tubes 5 are fixed on the front and rear ends of the cross bar 4 respectively. The interiors of the two outer tubes 5 are slidably connected with inner rods 6. A spring 7 is fixedly connected between the outer tubes 5 and the inner rod 6. A guide assembly 8 is fixedly connected to the bottom of the inner rod 6. A polishing assembly 9 is provided on the left side of the guide assembly 8. The polishing assembly 9 is linked to the guide assembly 8.

[0029] As a preferred embodiment, on the basis of the above structure, preferably, the guiding assembly 8 includes a mounting frame 81, a guide roller 82 and a drive motor 85. The mounting frame 81 is fixedly connected to the bottom end of the inner rod 6. The inner bearing of the mounting frame 81 is installed with a guide roller 82, and the guide roller 82 is driven by the drive motor 85. An auxiliary roller 11 is installed inside the right end of the processing table 1 to rotate corresponding to the guide roller 82. The auxiliary roller 11 and the guide roller 82 cooperate with each other to convey leather.

[0030] In this embodiment, the guide assembly 8 is controlled to move downward by the electric telescopic rod 3, so that the guide roller 82 can press the leather above the auxiliary roller 11. Then, the drive motor 85 is turned on to control the guide roller 82 to rotate, thereby realizing a compact transmission of the leather, which can avoid the problem of leather displacement during the polishing process and ensure the stable transmission and polishing of the leather during the polishing process.

[0031] On the basis of the above structure, the guiding assembly 8 further includes a first gear 83 and a fixed frame 84. The front and rear ends of the guide roller 82 are fixedly connected with the first gear 83. The first gear 83 is transmission-connected to the polishing assembly 9. The rear end outer wall of the mounting frame 81 is fixed with a fixed frame 84. The inner wall of the fixed frame 84 is fixedly installed with a drive motor 85. The output end of the drive motor 85 is fixedly connected to the center of the first gear 83 at the rear.

[0032] On the basis of the above structure, a groove 10 is further provided inside the right end of the processing table 1 and directly below the guide roller 82 , and both ends of the auxiliary roller 11 are rotatably mounted on the inner side of the groove 10 through bearings.

[0033] As a preferred embodiment, on the basis of the above structure, preferably, the polishing assembly 9 includes a polishing roller 91, a second gear 92, a connecting rod 93, a third gear 94 and a pull rod 95. The polishing roller 91 is located on the left side of the guide roller 82 and the two are linked. The front and rear ends of the polishing roller 91 are fixedly connected with the second gear 92. The outer sides of the front and rear ends of the polishing roller 91 are respectively bearing-connected with two connecting rods 93. The middle part of the side of the two connecting rods 93 facing away from each other is bearing-mounted with a third gear 94. The upper ends of the two connecting rods 93 are hinged with a pull rod 95, and the ends of the two pull rods 95 away from the connecting rod 93 are respectively hinged to the two outer tubes 5.

[0034] On the basis of the above structure, preferably, the end of the connecting rod 93 away from the polishing roller 91 is bearing-sleeved on the outer side of the end of the guide roller 82 .

[0035] On the basis of the above structure, preferably, both the second gear 92 and the first gear 83 are engaged with the third gear 94 .

[0036] On the basis of the above structure, preferably, the second gear 92 and the third gear 94 have the same diameter and length, and both are half the diameter and length of the first gear 83 .

[0037] On the basis of the above structure, preferably, the polishing roller 91 and the guide roller 82 have the same rotation direction, and the rotation speed of the polishing roller 91 is greater than the rotation speed of the guide roller 82 .

[0038] In this embodiment, when the guide roller 82 drives the first gear 83 to rotate, the second gear 92 and the polishing roller 91 can be driven to rotate through the third gear 94. Since the diameter of the first gear 83 is larger than that of the third gear 94 and the second gear 92, the polishing roller 91 can rotate in the same direction as the guide roller 82 at a faster speed, and the polishing roller 91 can fully cover the leather, thereby facilitating more thorough and efficient polishing of the leather in transmission.

[0039] The working principle of this utility model is as follows:

[0040] When in use, first place one end of the leather just above the auxiliary roller 11, then start the two electric telescopic rods 3 located on the top of the support frame 2 to control the crossbar 4, outer tube 5, inner rod 6, guide assembly 8 and polishing assembly 9 to move vertically downward synchronously. At this time, under the action of the spring 7, the guide assembly 8 and polishing assembly 9 are in a relatively static state, and the downward-moving guide roller 82 can be used to press the polished leather above the auxiliary roller 11. By pressing the leather, it is convenient to conduct the leather in a compact manner when the drive motor 85 is started to control the guide roller 82 to rotate, so as to avoid the problem of leather displacement during the polishing process and ensure the stable transmission and polishing of the leather during the polishing process.

[0041] After the guide roller 82 presses the leather tightly against the auxiliary roller 11, it is in a stationary state. When the electric telescopic rod 3 is controlled to continue to extend, the outer tube 5 can be moved downward relative to the inner rod 6, and the spring 7 can be compressed and contracted. When the outer tube 5 moves downward, the connecting rod 93 can be pushed by the pull rod 95 to rotate counterclockwise around the guide roller 82, so that the polishing roller 91 can be closely fitted to the leather surface, facilitating subsequent polishing.

[0042] When the connecting rod 93 is controlled to drive the polishing roller 91 to rotate and fit closely with the leather surface, the second gear 92 and the first gear 83 can always be meshed with the third gear 94. Since the diameter of the first gear 83 is larger than that of the second gear 92 and the third gear 94, the third gear 94 can transmit the power while the guide roller 82 and the first gear 83 rotate, so that the second gear 92 drives the polishing roller 91 to rotate in the same direction as the guide roller 82 at a faster speed. In addition, the polishing roller 91 can fully cover the leather, so that the leather being transported can be polished more fully and efficiently.

[0043] In the technical solution of the present invention, by linking the polishing assembly 8 and the guide assembly 9 so that the two share the same driving source, the number of installed motors can be reduced, the rational use of energy and the reduction of device costs can be achieved, and the practicality is higher.

[0044] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
