Detailed implementation manners

[0029] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0030] Such as Figures 1 to 2As shown in the figure, a hammer head pressing mechanism includes a mounting frame 1. The mounting frame 1 is provided with a guide rail assembly 2. The guide rail assembly 2 is provided with a driving assembly 3. A connecting rod 4 is vertically arranged below the driving assembly 3. The connecting rod 4 is slidably connected with a hammer head assembly 5. A buffer assembly 6 is arranged between the connecting rod 4 and the hammer head assembly 5, so that the hammer head assembly 5 buffers the force applied perpendicular to the connecting rod 4, so that when the hammer head assembly 5 presses the material package, the material package will not be damaged.

[0031] Specifically, as Figures 3 to 4 shown, the driving assembly 3 includes a cylinder 301. An installation seat 302 is arranged at the end of the cylinder rod of the cylinder 301. A connecting plate 303 is arranged below the installation seat 302. A support seat 304 is arranged below the connecting plate 303. The connecting rod 4 is arranged below the support seat 304. The telescopic movement of the cylinder rod of the cylinder 301 will drive the installation seat 302 to move up and down. The installation seat 302 will drive the support seat 304 to move up and down through the connecting plate 303. The support seat 304 will drive the connecting rod 4 and the hammer head assembly 5 to perform lifting operations.

[0032] The guide rail assembly 2 includes a frame 201. The frame 201 is fixedly connected with the mounting frame 1. The frame 201 is provided with a slider seat 202. The slider seat 202 is provided with an installation position 203. The cylinder 301 is arranged at the installation position 203. A plurality of second linear bearings 204 are arranged on both sides inside the slider seat 202. The second linear bearings 204 are slidably connected with a guide rod 205. A fixing plate 206 is arranged at the upper end of the guide rod 205. The lower end of the guide rod 205 is arranged on the installation seat 302. The slider seat 202 and the second linear bearings 204 are fixed. When the installation seat 302 moves up and down, it will drive the guide rod 205 to slide on the second linear bearings 204, so that the lifting of the driving assembly 3 is more stable.

[0033] Two first limit members 2021 are arranged at the upper end of the slider seat 202. Two second limit members 2022 are arranged at the lower end of the slider seat 202. The first limit members 2021 correspond to the fixing plate 206. The second limit members 2022 correspond to the installation seat 302.

The upper end of the buffer assembly 6 abuts against the bottom end of the connecting rod 4, and the lower end of the buffer assembly 6 abuts against the upper surface of the gasket 5032. The buffer assembly 6 is a compression spring. When the hammer head 503 moves downward and contacts the material package, under the action of the compression spring, the sliding cylinder 501 and the hammer head 503 will be driven to slide upward accordingly, so as to buffer the impact force generated when the hammer head 503 descends, so that while the hammer head 503 achieves the effect of pressing the material package, the material package will not be damaged.

[0036] As Figures 7 to 8 shown, a plurality of first mounting holes 5012 and second mounting holes 5013 are provided at the lower end of the sliding cylinder 501. A plurality of first fixing holes 5033 are provided at the upper end of the hammer head 503. A plurality of second fixing holes 5034 are provided on the gasket 5032.
