Description

Technical Field

[0001] This utility model relates to a disc-rotating stamping device, belonging to the field of stamping equipment. Background Technology

[0002] In the meat processing industry, especially in the production and distribution of pork carcasses, stamping is a crucial operation used to identify product information, quality certifications, or traceability codes, ensuring food safety and compliance with market regulations. Traditionally, stamping pork carcasses is mostly done manually, with operators using a handheld stamp to individually imprint each piece of pork. This method suffers from high labor intensity, low efficiency, and inconsistent stamp placement, making it unsuitable for large-scale production. Furthermore, manual stamping can lead to blurred imprints due to uneven pressure, affecting the clarity and readability of the markings.

[0003] In recent years, some automated stamping equipment has been introduced into the meat processing industry, such as stamping devices based on conveyor belts and robotic arms. While these devices have improved efficiency to some extent, they generally suffer from drawbacks such as complex structure, large footprint, and high maintenance costs. Especially for stamping pork carcasses, existing equipment struggles to adapt to the irregular, soft, and deformable surface of pork, resulting in insufficient stamping accuracy, misaligned imprints, or uneven ink adhesion. Furthermore, ink replenishment in existing devices typically requires manual intervention, limiting automation and hindering continuous and efficient stamping operations.

[0004] Therefore, an automated stamping device with a compact structure, stable operation, and accurate stamping is designed specifically for the characteristics of pork carcasses. It can achieve efficient and continuous stamping operations while reducing manual intervention and improving production efficiency and labeling quality. Utility Model Content

[0005] The purpose of this invention is to provide a rotating disc stamping device that can effectively solve the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The device includes a frame fixed to the outer shell, and a rotating structure rotatably disposed within the outer shell. The rotating structure includes a turntable with sliding structures evenly distributed around its circumference. Each sliding structure consists of a mounting base fixed to the turntable, a slider with a groove fixed to one side of the mounting base, and a slide rail that slides in the groove. A stamping component is fixed on the slide rail. Furthermore, an ejection structure for pushing out the stamping component is also provided on the frame.

[0008] Further: The turntable is driven by a rotating motor, and the rotating motor is fixed to the outer shell through an inner shell; a "convex"-shaped mounting groove is provided on the circular end face of the turntable, and one end of the mounting seat is fixed in the mounting groove.

[0009] Further: The pushing structure includes a pushing cylinder. The cylinder body part of the pushing cylinder is fixed to the outer shell through a first fixing ring. A limiting block is provided at the piston end of the pushing cylinder. The limiting block is fixed to the outer shell through a second fixing ring, and the piston end of the pushing cylinder is slidably arranged in the limiting block.

[0010] Further: The stamping component includes a connecting seat fixed to the slide rail. One end of the connecting seat is connected with a stamping head through a spring, and a limiting rod is slidably arranged in the connecting seat. One end of the limiting rod is fixed to the stamping head, and the limiting rod is located inside the spring.

[0011] Further: A matching structure for cooperating with the connecting seat is also provided at the piston end of the pushing cylinder. The matching structure includes a clamping seat with a clamping groove fixed to the other end of the connecting seat and a clamping ring fixed to the piston end of the pushing cylinder. [[ID=ll]]

[0012] Further: A limiting ring for the connecting seat to rotate stably with the turntable is also provided between the connecting seat and the outer shell. The limiting ring and the second fixing ring are connected by four fixing rods; the framework includes the first fixing ring, the second fixing ring, and the limiting ring; the outer shell includes a first protection plate between the first fixing ring and the second fixing ring, a second protection plate between the second fixing ring and the limiting ring, a third protection plate fixed to the end face of the limiting ring, and a cover plate fixed to the third protection plate; the inner shell is fixed to the first fixing ring.

[0013] Further: An automatic ink filling structure is also provided on the end face of the cover plate. The automatic ink filling structure includes a first fixing block and a second fixing block fixed to the end face of the cover plate. A driving cylinder is hinged to the first fixing block. The piston end of the driving cylinder is rotatably connected with an extension arm. The middle part of the extension arm is rotatably arranged on the second fixing block through a rotating shaft, and an ink cover is fixed to the end of the extension arm.

[0014] The beneficial effects are as follows:

[0015] 1. Through the circumferential movement of the turntable and the radial sliding of the sliding structure for precise positioning on the surface of white-striped pork, and by using the spring of the stamping component, it adapts to the irregular and soft deformation characteristics of the pork surface, ensuring that the imprint position is accurate and clearly distinguishable.

[0016] 2. The synergistic effect of the ejection structure and the mating structure allows the stamping assembly to smoothly connect with the ejection structure after rotation, enabling the push cylinder to stably push the stamping head to stamp.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] See Figure 1-7 This is one embodiment of the rotary stamping device of this utility model, used to achieve efficient and accurate automated stamping operation. The overall structure of the device includes a shell 1, a frame 2 fixed on the shell 1, and a rotating structure 3 rotatably disposed within the shell 1.

[0034] like Figure 1 and Figure 2 As shown, the structure of the outer shell 1 and the frame 2 is as follows: the outer shell 1 is mainly used to protect the entire equipment, while the frame 2 is used to install some devices of the entire equipment.

[0035] The outer casing 1 consists of a first protective plate 11, a second protective plate 12, a third protective plate 13, and a cover plate 14, forming the external protection of the device. The frame 2 includes a first fixing ring 21, a second fixing ring 22, a limiting ring 23, and four fixing rods 24 connecting the limiting ring 23 and the second fixing ring 22. The first fixing ring 21 is used to fix the inner shell 33 of the rotating motor 32 and the cylinder body of the pushing cylinder 61. The second fixing ring 22 is used to fix the limiting block 62. The limiting ring 23 ensures that the stamping assembly 5 rotates stably with the turntable 31. The fixing rods 24 fix the second fixing ring 22 and the limiting ring 23 together.

[0036] like Figure 3 and Figure 4 As shown, the rotating structure 3 is the core component that controls the rotation of the stamping assembly 5. There are 10 stamping assemblies 5 in this device, and each stamping assembly 5 is equipped with different text, which is suitable for stamping pork with different markings. When the pork is conveyed to the front of the stamping assembly 5, the rotating structure 3 drives the stamping assembly 5 to rotate, and after the required text is rotated to the position where the stamping head 53 is pushed out, the pushing structure 6 is used to stamp the stamping head 53 onto the pork to complete the stamping. During this process, the stamping head 53 is restricted by the sliding structure 4 to achieve linear movement and achieve the function of accurately and stably stamping the pork.

[0037] The rotating structure 3 of this device includes a turntable 31, a rotating motor 32, and an inner shell 33. The turntable 31 is circular and driven by the rotating motor 32, which is fixed to the first fixing ring 21 via the inner shell 33. The circular end face of the turntable 31 is provided with multiple "U"-shaped mounting grooves 34, which are used to fix the mounting base 41 of the sliding structure 4. The rotating motor 32 is a servo motor with adjustable speed to ensure precise positioning of the turntable 31. The inner shell 33 is fixed to the first fixing ring 21 by bolts, providing stable support for the rotating motor 32.

[0038] like Figure 4 and Figure 6 As shown, the sliding structures 4 of this device are evenly distributed along the circumference of the turntable 31, corresponding to the number of stamping components 5, with ten sets in total, to improve stamping efficiency. Each set of sliding structures 4 includes a mounting base 41, a slider 42, and a slide rail 44. One end of the mounting base 41 is fixed to the mounting groove 34 of the turntable 31 by bolts, and the other end is connected to the slider 42. The slider 42 is provided with a groove, and the slide rail 44 slides within the groove. The inner wall of the groove is coated with a lubricating coating to ensure smooth sliding. The stamping components 5 are fixed on the slide rail 44, and the sliding distance meets the radial movement requirements of the stamping action.

[0039] like Figure 7As shown, the stamping assembly 5 of this device includes a connecting seat 51, a spring 52, a stamping head 53, and a limiting rod 54. The connecting seat 51 is fixed to the slide rail 44 by bolts, and one end of it is connected to the stamping head 53 via the spring 52. The spring 52 is a compression spring, providing elastic force for stamping and resetting. The limiting rod 54 is slidably disposed inside the connecting seat 51, and one end of the limiting rod 54 is welded to the stamping head 53, located inside the spring 52, to ensure stable operation of the stamping head 53. The surface of the stamping head 53 is engraved with text and patterns.

[0040] The ejection structure 6 of this device includes a push cylinder 61 and a limiting block 62. The cylinder body of the push cylinder 61 is fixed to the outer casing 1 by a first fixing ring 21. The push cylinder 61 is a double-acting cylinder. A limiting block 62 is provided at the piston end, and the limiting block 62 is fixed to the outer casing 1 by a second fixing ring 22. The piston end slides within the limiting block 62, and a guide groove is provided within the limiting block 62 to ensure smooth piston movement. The action of the push cylinder 61 is controlled by a PLC controller, providing a rapid response.

[0041] Since the pushing cylinder 61 in this device is in a fixed state, while the entire stamping assembly 5 is in a circular motion state, the stamping assembly 5 needs to rotate to a designated position before it can be acted upon by the pushing cylinder 61. Therefore, in order for the pushing cylinder 61 to push the stamping assembly 5 to move, a matching structure 7 is also provided in this device.

[0042] like Figure 5 As shown, the mating structure 7 includes a retaining seat 71 fixed on the connecting seat 51 and a retaining ring 73 fixed on the piston end. The retaining seat 71 has a retaining groove 72, and the retaining ring 73 matches the retaining groove 72. Through the engagement of the retaining ring 73 and the retaining groove 72, the push cylinder 61 precisely drives the connecting seat 51, ensuring the stable and reliable ejection of the stamping assembly 5. When the entire connecting seat 51 rotates to a certain position, the retaining ring 73 located at the end of the push cylinder 61 enters the retaining groove 72 of the retaining ring 73. At this time, the push cylinder 61 operates, pushing the entire connecting seat 51 to stamp the pork.

[0043] like Figure 7 As shown, the automatic inking structure can automatically ink the text on the stamp head 53, avoiding the situation where the stamp head 53 is out of ink and cannot stamp the text on the pork.

[0044] The automatic inking structure 8 includes a first fixing block 81, a second fixing block 82, a drive cylinder 83, an extension arm 84, a rotating shaft 85, and an ink cap 86. The first fixing block 81 and the second fixing block 82 are bolted to the cover plate 14. The drive cylinder 83, a single-acting cylinder, is hinged to the first fixing block 81. The piston end is connected to the extension arm 84 via a hinge. The middle of the extension arm 84 is rotatably mounted on the second fixing block 82 via the rotating shaft 85. The ink cap 86 is fixed to the end of the extension arm 84. The ink cap 86 has a built-in ink-absorbing sponge to replenish ink to the stamping head 53. When the drive cylinder 83 extends, the extension arm 84, constrained by the rotating shaft 85, can open or close the ink cap 86, thus replenishing ink to the stamping head 53.

[0045] Work process

[0046] 1. Initial positioning: The rotating motor 32 starts and drives the turntable 31 to rotate, positioning the stamping assembly 5 on a set of sliding structures 4 to the stamping station.

[0047] 2. Ink replenishment: The drive cylinder 83 is activated, which drives the extension arm 84 to rotate around the rotating shaft 85, so that the ink cap 86 contacts the stamp head 53 to replenish the ink.

[0048] 3. Stamping action: The cylinder 61 is activated, and the retaining ring 73 at the piston end engages with the groove 72 of the retaining seat 71, pushing the connecting seat 51 to slide outward along the slide rail 44. The stamping head 53 contacts the document surface under the elastic force of the spring 52, and the limiting rod 54 ensures smooth operation.

[0049] 4. Reset: Push the cylinder 61 to reset, the spring 52 drives the stamp head 53 to return to its original position, and the connecting seat 51 slides back to the initial position along the slide rail 44.

[0050] 5. Cyclic operation: Turntable 31 continues to rotate, and the next set of stamping components 5 enters the stamping station, repeating the above process to achieve continuous stamping.

[0051] Technical effects:

[0052] The rotary stamping device in this embodiment achieves precise positioning and stable operation of the stamping component 5 through the circular motion of the turntable 31 and the radial sliding of the sliding structure 4. The cooperating structure 7 and the ejection structure 6 ensure reliable operation, while the automatic inking structure 8 reduces manual intervention. The overall structure is compact and suitable for stamping pork carcasses.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
