Description

Technical Field

[0001] The utility model relates to the technical field of printing label sorting, in particular to a knocking device for sorting small-sized printing labels. Background Technique

[0002] With the acceleration of the globalization and informatization processes, labels, as an important information carrier, have been widely used in all walks of life. From product packaging, logistics management to identity recognition, labels are playing an irreplaceable role. As an important form of labels, printing labels are increasingly favored by people due to their exquisite appearance and rich information-carrying capacity. In this context, the manufacturing technology and applications of printing labels are also constantly developing and improving to meet the growing market demands.

[0003] In the label production process, the stamping and detachment of label hooks are indispensable steps. Hooks are usually stamped on plates for subsequent fixing of labels on products. However, after the hooks are stamped, they need to be detached from the plates for the next steps of label processing and packaging. Traditional detachment methods mainly rely on manual operations, where operators use tools such as hammers to knock the hooks to make them detach from the plates.

[0004] Such operation methods are not efficient. Each hook needs to be knocked separately, making the whole process time-consuming. In addition, operators need to continuously perform knocking actions, with a high labor intensity, which easily causes fatigue and may even cause harm to the body. During the process of knocking the hooks, it is difficult for operators to ensure that the force and position are accurate every time, which may result in incomplete detachment of the hooks, thereby causing unnecessary damage to the hooks. This will affect subsequent processing and use, and may even lead to material waste.

[0005] Based on this, the utility model designs a knocking device for sorting small-sized printing labels to solve the above problems. Content of the Utility Model

[0014] Furthermore, the plurality of knocking rods are adapted to the plurality of reciprocating shifting rods, and the reciprocating shifting rods are movably connected to the knocking rods;

[0015] Furthermore, the limiting mechanism includes a lower pressing plate, a connecting rod, a connecting plate and an electric push rod.

[0031] The "left", "right", "front", "rear", "upper" and "lower" mentioned in the following description are oriented in the perspective direction of the three-dimensional Figure 1 view.

[0032] Embodiment 1

[0033] In some embodiments, please refer to the accompanying drawings of the specification Figures 1-6, A knocking device for sorting small-sized printed labels, comprising a frame 1, a conveying mechanism 2, limiting rods 3, a knocking mechanism 4 and a limiting mechanism 5. The conveying mechanism 2 is fixedly installed inside the frame 1. Limiting rods 3 are fixedly connected to the edges on both the front and rear sides of the top of the conveying mechanism 2. The knocking mechanism 4 is connected to the front side of the frame 1. Two groups of limiting mechanisms 5 are connected to the top of the two limiting rods 3, and the two groups of limiting mechanisms 5 are respectively arranged on the left and right sides of the knocking mechanism 4;

[0034] The knocking mechanism 4 includes a first mounting frame 41, a fixed rod 42, a knocking rod 43, a rotating rod 46 and a reciprocating shifting rod 47. The first mounting frame 41 is fixedly installed on the front side wall of the frame 1. A fixed rod 42 is fixedly connected to the side of the first mounting frame 41 close to the frame 1. A plurality of knocking rods 43 are rotatably connected to the fixed rod 42. A rotating rod 46 is arranged on the front side of the fixed rod 42. The rotating rod 46 is rotatably connected to the first mounting frame 41. A plurality of reciprocating shifting rods 47 are fixedly connected to the rotating rod 46 at equal intervals.

[0035] The workpiece to be sorted is conveyed to the right by the conveying mechanism 2, and the workpiece is limited by the limiting rods 3 to avoid the problem of inaccurate knocking caused by the position deviation of the workpiece during the conveying process. When the knocking mechanism 4 works, the rotating rod 46 is driven to rotate by the driving assembly 48. The rotating rod 46 drives a plurality of reciprocating shifting rods 47 to rotate. The reciprocating shifting rods 47 push the tail ends of the knocking rods 43, causing the knocking rods 43 to make reciprocating motions, thereby driving the knocking heads 44 to knock the workpiece to achieve the purpose of sorting. The workpiece is pressed and limited by the limiting mechanism 5 to ensure the stability of the workpiece during knocking and sorting, prevent the workpiece from warping and causing inaccurate knocking, with high sorting efficiency, accurate sorting and strong practicability.

[0036] Furthermore, the conveying mechanism 2 includes a driving roller 21, a driven roller 22 and a conveying belt 23. The driving roller 21 is rotatably connected to the left side of the frame 1, and the driven roller 22 is rotatably connected to the right side of the frame 1. There are two conveying belts 23. Both of the two conveying belts 23 are sleeved on the driving roller 21 and the driven roller 22, and the two conveying belts 23 are respectively arranged at the front and rear ends of the driving roller 21 and the driven roller 22. The workpiece is conveyed by the two conveying belts 23 on both sides. While ensuring the stable conveying of the workpiece, there is a gap in the middle, which is convenient for the knocking mechanism 4 to knock the workpiece, and the sorted and dropped workpiece can fall into the receiving box 7 arranged at the bottom for collection, avoiding the problem of inaccurate knocking caused by the position deviation of the workpiece.

[0037] Furthermore, guiding blocks 31 are fixedly connected to the left sides of the limiting rods 3. The guiding blocks 31 are of a slope structure, which is convenient for guiding the workpiece between the two limiting rods 3, avoiding the skew of the workpiece conveying and improving the stability of the workpiece conveying.

[0038] Furthermore, the knocking mechanism 4 further includes a knocking head 44, a limiting block 45 and a driving assembly 48. The knocking heads 44 are fixedly connected to the bottom of the knocking rods 43 at equal intervals. The limiting block 45 is arranged between two adjacent knocking rods 43. The limiting block 45 is fixedly connected to the fixed rod 42. A driving assembly 48 is connected to the right side of the first mounting bracket 41. The knocking head 44 is used to knock the workpiece. The limiting block 45 is used to limit two adjacent knocking rods 43 to prevent interference between the knocking rods 43. The driving assembly 48 is used to drive the rotating rod 46 to rotate, and then drive the reciprocating lever 47 to rotate, so as to realize the reciprocating movement of the knocking rod 43.

[0039] Furthermore, the driving assembly 48 includes a driven wheel 481, a driving wheel 482, a transmission belt 483, a servo motor 484 and a second mounting bracket 485. The driven wheel 481 is fixedly connected to the right end of the rotating rod 46. The transmission belt 483 is sleeved on the driven wheel 481. The driving wheel 482 is connected inside the transmission belt 483. The driven wheel 481 is in transmission connection with the driving wheel 482 through the transmission belt 483. A servo motor 484 is arranged on the right side of the driving wheel 482. The output end of the servo motor 484 is fixedly connected to the driving wheel 482. The bottom of the servo motor 484 is fixedly connected to the second mounting bracket 485. The second mounting bracket 485 is fixedly connected to the front side of the frame 1. The servo motor 484 drives the driving wheel 482 to rotate. The driving wheel 482 drives the driven wheel 481 to rotate through the transmission belt 483. The driven wheel 481 drives the rotating rod 46 to rotate, so as to realize the reciprocating movement of the knocking rod 43. By controlling the rotation speed of the rotating rod 46 by the servo motor 484, the knocking frequency of the knocking rod 43 is controlled, so as to control the knocking force.

[0040] Furthermore, a plurality of knocking rods 43 are adapted to a plurality of reciprocating levers 47, and the reciprocating levers 47 are movably connected to the knocking rods 43. During the rotation of the reciprocating levers 47, the top ends thereof will contact the tail ends of the knocking rods 43, pushing the tail ends of the knocking rods 43 to move upward, and then driving the knocking heads 44 to move downward to knock the workpiece. When the reciprocating levers 47 continue to rotate, the top ends thereof gradually move away from the tail ends of the knocking rods 43. At this time, the knocking rods 43 move downward under the action of gravity, realizing the reciprocating movement of the knocking rods 43, and then realizing the continuous knocking action on the workpiece.

[0041] Further, the limiting mechanism 5 includes a lower pressing plate 51, a connecting rod 52, a connecting plate 53 and an electric push rod 54. The lower pressing plate 51 is arranged directly above the conveyor belt 23. The top of the lower pressing plate 51 is fixedly connected with the connecting rod 52. The top of the connecting rod 52 is fixedly connected with the connecting plate 53. An electric push rod 54 is arranged on the side of the connecting plate 53 away from the machine frame 1. The output end at the top of the electric push rod 54 is fixedly connected to the connecting plate 53. The electric push rod 54 is fixedly installed on the limiting rod 3, which can avoid the problem of warping when the workpiece is being knocked and sorted, and improve the accuracy of workpiece sorting.

[0042] Further, support frames 6 are fixedly connected to both the left and right sides of the bottom of the machine frame 1. The support frames 6 support the machine frame 1 to improve the stability of the machine frame 1. A receiving box 7 is arranged at the bottom of the machine frame 1. The receiving box 7 is arranged directly below the knocking mechanism 4. The receiving box 7 is used to collect the workpieces knocked off from the conveyor belt 23 by the knocking mechanism 4, which is convenient for subsequent collection work.

[0043] The working principle of the present utility model: When in use, first place the workpiece to be sorted on the conveyor belt 23. By rotating the driving roller 21 and the driven roller 22, the conveyor belt 23 is driven to rotate by the driving roller 21 and the driven roller 22, so as to convey the workpiece to the right. During the conveyance of the workpiece, the workpiece is guided between the two limiting rods 3 by the guiding block 31 to limit the workpiece and prevent the workpiece from being conveyed obliquely. Then the workpiece continues to be conveyed to the right to the lower part of the knocking mechanism 4. At this time, the rotating rod 46 is driven to rotate by the driving assembly 48. The rotating rod 46 drives a plurality of reciprocating rods 47 to rotate. When the top end of the reciprocating rod 47 contacts the tail end of the knocking rod 43, it pushes the tail end of the knocking rod 43 to move upward, and then drives the knocking head 44 to move downward to knock the workpiece. When the reciprocating rod 47 continues to rotate and its top end gradually moves away from the tail end of the knocking rod 43, at this time, the knocking rod 43 moves downward under the action of gravity, realizing the reciprocating movement of the knocking rod 43, and then realizing the continuous knocking action on the workpiece. When the workpiece is knocked to the preset strength, the workpiece falls from the conveyor belt 23 into the receiving box 7 for collection, realizing the sorting of the workpiece. At the same time, the electric push rod 54 drives the lower pressing plate 51 to move downward to press and limit the workpiece on the conveyor belt 23, avoiding the problem of warping when the workpiece is being knocked and sorted, and improving the accuracy of workpiece sorting. This device has a simple structure and is easy to use. It can realize the continuous knocking action on the workpiece, and can control the knocking strength, realize the sorting of different workpieces, improve the sorting efficiency and accuracy, and has strong practicability.
