Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a lifting mechanism for feeding in the grinding production of offset printing inks. Background Art
[0002] Offset printing ink is a complex ink specially designed for offset printing machines. It occupies an important position in the printing industry due to its high-quality printing effect, high printing speed, low cost, and wide applicability. The production of offset printing ink includes processes such as mixing and grinding and dispersion. After the raw materials are mixed, they need to be added to the grinding and dispersion equipment. However, due to the relatively high feeding port of the grinding and dispersion equipment, the traditional manual feeding method is not only inconvenient to operate but also has certain safety hazards.
[0003] Therefore, the current feeding method is that the operator drives a manual forklift to clamp the material bucket containing the mixed materials, uses the lifting mechanism of the manual forklift to lift the material bucket to a corresponding height and tilt the material bucket so that the mixed materials in the material bucket are put into the grinding and dispersion equipment, thereby replacing manual feeding. Although using this feeding method can reduce the labor intensity, there are still many problems in the feeding process. Due to the lack of fixing components for the material bucket, the material bucket is prone to jitter or overturn during lifting and tilting, resulting in the overflow and scattering of the mixed materials. This not only affects the smoothness of feeding but also may pollute the production environment and even cause safety accidents. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.
[0020] A lifting mechanism for feeding in the grinding production of offset printing ink in this embodiment, referring to the attached Figure 1 , includes a gantry 1, a lifting component 2, a locking component 3, a swinging component 4, a lifting bracket 5 and a barrel fixing bracket 6. The lifting component 2 is arranged inside the gantry 1. The lifting end of the lifting bracket 5 is connected to the lifting component 2. The two sides of the lifting bracket 5 are slidably matched with the inner side of the gantry 1. The swinging component 4 is arranged on the lifting bracket 5. The barrel fixing bracket 6 is arranged at the movable end of the swinging component 4. A fixing cavity matching the shape of the material barrel is arranged inside the barrel fixing bracket 6. A telescopic fastening component 7 is arranged at the top of the barrel fixing bracket 6. The fastening component 7 is used for fastening the upper edge of the fixed material barrel. The locking component 3 is arranged on both sides of the lifting bracket 5. When the lifting bracket 5 is lifted to the feeding position driven by the lifting component 2, the locking component 3 is locked with the inner side of the gantry 1.
[0021] On the fixed barrel bracket 6 of this embodiment, a fixed cavity matching the material barrel is provided, and a telescopic fastening component 7 is provided at the top of the fixed barrel bracket 6. When placing the material barrel, the fastening component 7 can extend out to avoid interfering with the material barrel. After the material barrel is completely placed in the fixed cavity, the fastening component 7 is pressed against the material barrel, thereby fastening the upper edge of the fixed material barrel. Thus, the radial and axial limits of the material barrel are achieved through the fastening component 7 and the fixed cavity, solving the problem of the safety hazard caused by the easy displacement, loosening of the clamping position, and thus easy slipping of the material barrel in the prior art. Driven by the lifting component 2 and the swinging component 4, the stable lifting and pouring of the material barrel can be realized.
[0022] Preferably, the fastening component 7 includes a telescopic rod 71 and a reverse hook portion 72. The telescopic rod 71 is arranged outside the fixed barrel bracket 6, and the reverse hook portion 72 is arranged at the top of the telescopic rod 71. The reverse hook portion 72 extends along the inner side of the fixed barrel bracket 6. The reverse hook portion 72 is used to abut against the upper edge of the material barrel. The telescopic rod 71 can be telescoped and fixed in the up and down direction.
[0023] By arranging the reverse hook portion 72 at the top of the telescopic rod 71 and making the reverse hook portion 72 extend along the inner side of the fixed barrel bracket 6, it can closely abut against the upper edge of the material barrel. Thus, the reverse hook portion 72 and the bottom of the fixed barrel bracket 6 respectively abut against the upper edge and the bottom of the material barrel, effectively preventing the material barrel from shaking or shifting during the feeding process. By setting the telescopic rod 71, the fastening component 7 can adapt to material barrels of different heights, and has a wider application range.
[0024] Further, the fastening component 7 further includes a limiting cylinder 73 and a fixed pin 74. The limiting cylinder 73 is arranged outside the fixed barrel bracket 6, the telescopic rod 71 is arranged in the limiting cylinder 73 and is in sliding fit with the inner wall of the limiting cylinder 73. At least one first limiting hole is provided at the bottom of the limiting cylinder 73, and a second limiting hole is provided at the bottom of the telescopic rod 71. The fixed pin 74 is detachably connected to the first limiting hole and the second limiting hole. Thus, through the sliding fit of the telescopic rod 71 and the limiting cylinder 73, the lifting movement of the reverse hook portion 72 is realized, so that the reverse hook portion 72 is far away from the fixed barrel bracket 6 when placing the material barrel to avoid interference, and the fixation of material barrels of different heights can be realized. Through the correspondence of the fixed pin 74 with the first limiting hole and the second limiting hole, the fixation of the reverse hook portion 72 is realized, so that the reverse hook portion 72 can abut against the upper edge of the material barrel to ensure the stability of the fixation of the material barrel.
[0025] Preferably, the locking component includes two anti-falling components, the two anti-falling components are respectively arranged on both sides of the lifting bracket, and the locking ends of the anti-falling components cooperate with the gantry.
[0026] In this embodiment, the force for the lifting bracket 5 to hover at the feeding height is provided by the lifting assembly 2. The anti-falling assembly is only used for anti-falling to prevent the material bucket from falling due to the loss of power caused by the failure of the lifting assembly 2, ensuring the safety of the operator's feeding operation. When the lifting assembly 2 drives the lifting bracket 5 and the bucket-fixing bracket 6 to rise to the feeding position, through the cooperation of the anti-falling assembly and the gantry 1, the anti-falling function is achieved, ensuring the stability of the material bucket during the feeding process. If a fall occurs, the anti-falling assembly plays a limiting role on the lifting bracket to achieve the anti-falling effect. Thus, after the feeding is completed, the operator needs to first unlock the two-sided anti-falling assembly by pulling the unlocking handle 31 of the anti-falling assembly, and then the lifting assembly 2 drives the lifting bracket 5 to descend, thereby ensuring that the material bucket can only descend after the operator confirms the safe state.
[0027] Preferably, the lifting assembly 2 includes a hydraulic cylinder 21, a first sprocket 22, a second sprocket 23, a first chain 24 and a second chain 25. The hydraulic cylinder 21 is arranged on one side of the gantry 1, the first sprocket 22 is arranged on the side of the gantry 1 close to the hydraulic cylinder 21, the second sprocket 23 is arranged on both sides of the gantry 1, the starting ends of the first chain 24 and the second chain 25 are both connected to the telescopic end of the hydraulic cylinder 21, the first chain 24 meshes with the first sprocket 22, and the end of the first chain 24 is connected to the side of the lifting bracket 5 close to the hydraulic cylinder 21. The second chain 25 meshes with the two second sprockets 23 in sequence, and the end of the second connection is connected to the side of the lifting bracket 5 far from the hydraulic cylinder 21. Thus, by driving the first chain 24 and the second chain 25 to mesh with the first sprocket 22 and the second sprocket 23 respectively through the telescopic movement of the hydraulic cylinder 21, the lifting and lowering movement of the lifting bracket 5 can be controlled.
[0028] Preferably, the swinging assembly 4 includes a swinging motor 41 and a gear transmission component 42. The swinging motor 41 is arranged on one side of the lifting bracket 5, the rotating shaft end of the swinging motor 41 is connected to the input end of the gear transmission component 42, and the output end of the gear transmission component 42 is connected to the bucket-fixing bracket 6. Thus, through the cooperation of the swinging motor 41 and the gear transmission component 42, the bucket-fixing bracket 6 rotates relative to the lifting bracket 5, and the control of the tilting action of the material bucket can be realized to complete the feeding.
[0029] Furthermore, the swinging assembly 4 further includes a swinging shaft and a bearing seat 43. The bearing seat 43 is fixed on the other side of the lifting bracket 5. The swinging shaft is coaxial with the output end of the gear transmission component 42 and is arranged on the other side of the bucket-fixing bracket 6, and the swinging shaft is connected to the movable end of the bearing seat 43.
[0030] Preferably, it further includes a bucket-fixing strap, and the bucket-fixing strap is arranged on the bucket-fixing bracket 6. With the bucket-fixing strap, when fixing the material bucket, the outer side of the material bucket can be fastened to the bucket-fixing bracket 6 through the bucket-fixing strap, further improving the stability of fixing the material bucket.
[0031] Preferably, it also includes guide rails 81 and pulleys 82, wherein the guide rails 81 are arranged on both sides of the gantry 1, and the pulleys 82 are arranged on both sides of the lifting bracket 5, and the pulleys 82 are slidably matched with the guide rails 81. Thus, the lifting bracket 5 and the gantry 1 are slidably matched, which plays a role in guiding the lifting movement of the lifting bracket 5.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
