Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, specifically to an adjustable gap planar embossing conveyor mechanism. Background Technology
[0002] Flat embossing technology plays a vital role in paper processing. It primarily uses mechanical pressure to create raised or recessed textures on the paper surface, thereby enhancing the product's aesthetics and functionality. This process is widely used in high-end paper products such as packaging, decoration, and stationery. It not only enhances the paper's three-dimensionality and visual depth but also improves its tactile feel or anti-slip properties through specific textures. For example, embossing delicate geometric patterns on gift boxes can elevate the product's perceived quality, while embossing on specialty papers can simulate the effects of leather and fabric, meeting diverse design needs. Furthermore, the embossing process does not alter the paper's physical properties, making it an environmentally friendly surface treatment method.
[0003] In existing technologies, traditional embossing equipment generally suffers from poor adjustability. Most machines use a fixed-gap double-roller structure, requiring manual adjustment of the embossing roller gap when changing to different paper thicknesses. This is not only cumbersome but also makes it difficult to guarantee accuracy. Some machines with adjustment functions rely on complex hydraulic or gear systems, resulting in bulky structures and high maintenance costs. During continuous production, the lack of real-time adjustment capability easily leads to uneven embossing depth due to fluctuations in paper thickness. Furthermore, changing the embossing mold usually requires disassembling the entire roller shaft, which is time-consuming and labor-intensive. To address these issues, we propose an adjustable-gap planar embossing conveyor mechanism. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an adjustable gap planar embossing conveyor mechanism that can flexibly adjust the embossing gap and quickly change the embossing mold, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable gap planar embossing conveying mechanism, including a mounting platform and an adjustment component; Mounting platform: A groove is provided on the upper side, and a belt conveyor is installed inside the groove; Adjustment assembly: includes a mounting box, a mounting frame, a first motor, a movable frame, and a bidirectional screw. The mounting box is fixed to the left end of the front side of the mounting platform. The mounting frame is fixed to the upper side of the mounting box. The first motor is installed inside the mounting frame. Two corresponding movable frames are slidably connected to the front side inside the mounting box. The upper side of the movable frame has threaded holes with opposite threads. The two threaded holes are internally threaded with a bidirectional screw. The bidirectional screw is welded from two threaded rods with opposite threads. The bidirectional screw is rotatably connected inside the mounting box. The output shaft of the first motor is fixed to the upper end of the bidirectional screw. A rotating assembly is installed on the rear side of the movable frame. An embossing assembly is installed on the surface of the rotating assembly. A fixing assembly and an extrusion assembly are installed inside the rotating assembly. The fixing assembly and the extrusion assembly cooperate to adjust the distance between the two rotating barrels by setting the adjustment assembly. Wherein: the input ends of the first motor and the belt conveyor are both electrically connected to the output ends of an external control switch group.
[0006] Furthermore, the rotating assembly includes a fixed box, a second motor, and a rotating drum. The fixed box is fixed to the rear side of the moving frame. The second motor is installed inside the fixed box. The rotating drum is rotatably connected to the rear side of the fixed box. The output shaft of the second motor is fixed to the front end of the rotating drum. The input end of the second motor is electrically connected to the output end of an external control switch group. The rotating assembly drives the embossing assembly to rotate.
[0007] Furthermore, the embossing assembly includes a retaining strip and an embossing ring. Three corresponding strip grooves are formed on the circumferential surface of the rotating drum. A retaining strip is engaged inside the strip groove. An embossing ring is fitted onto the circumferential surface of the rotating drum. All three retaining strips are fixed inside the embossing ring. The embossing assembly is used to emboss the paper.
[0008] Furthermore, the fixing component includes a clamping plate, a connecting strip, and springs. The interior of the rotating barrel has three corresponding strip-shaped openings, and the clamping plate is slidably connected inside the strip-shaped openings. The side of the clamping strip has a slot, and the clamping plate is engaged inside the corresponding slot. The connecting strip is fixed to the side of the clamping plate inside the rotating barrel, and two corresponding springs are fixed to the side of the connecting strip. All the springs are fixed inside the two rotating barrels respectively. The embossing component is fixed by setting the fixing component.
[0009] Furthermore, the extrusion assembly includes an internal threaded ring, a threaded column, an extrusion cone, and a turntable. The internal threaded ring is fixed to the rear end inside the turntable. The internal threaded ring is connected to the threaded column by its internal thread. The front end of the threaded column is fixed to the extrusion cone. The extrusion cone is located between its three corresponding connecting strips. The rear end of the threaded column is fixed. The extrusion cone is used to extrude the three corresponding connecting strips.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable gap planar embossing conveyor mechanism has the following advantages: 1. By coordinating the bidirectional screw in the adjustment component with the first motor, the two moving frames can move synchronously in opposite directions, thereby precisely adjusting the distance between the two rotating drums. This design solves the drawback of traditional equipment requiring manual adjustment after stopping the machine. It not only significantly improves the adaptability to paper of different thicknesses, but also ensures the uniformity of pressure distribution during the embossing process, effectively avoiding the problem of inconsistent embossing depth caused by fluctuations in paper thickness, and greatly improving the stability of continuous production and the consistency of finished products. 2. The embossing assembly adopts a nested structure of the clamping strip and the embossing ring, combined with the clamping plate fixing mechanism driven by the spring inside the rotating drum. The clamping lock can be released by simply operating the extrusion cone. This modular design eliminates the cumbersome process of disassembling the roller shaft in the traditional way, simplifies the embossing ring replacement operation to the minute level, significantly shortens the equipment downtime, and improves the production efficiency.

The mounting box 21 is fixed to the left front end of the mounting platform 1. The mounting bracket 22 is fixed to the upper side of the mounting box 21. The first motor 23 is installed inside the mounting bracket 22. Two corresponding movable brackets 24 are slidably connected to the front side inside the mounting box 21. Threaded holes with opposite threads are opened on the upper side of the movable brackets 24. A bidirectional screw 25 is threaded into the two threaded holes. The bidirectional screw 25 is formed by welding two threaded rods with opposite threads. The bidirectional screw 25 is rotatably connected inside the mounting box 21. The output shaft of the first motor 23 is fixed to the bidirectional screw 25. At the upper end, a rotating assembly 3 is installed on the rear side of the movable frame 24. An embossing assembly 4 is installed on the surface of the rotating assembly 3. A fixing assembly 5 and an extrusion assembly 6 are installed inside the rotating assembly 3. The fixing assembly 5 and the extrusion assembly 6 cooperate with each other. The rotating assembly 3 includes a fixing box 31, a second motor 32, and a rotating drum 33. The fixing box 31 is fixed to the rear side of the movable frame 24. The second motor 32 is installed inside the fixing box 31. The rotating drum 33 is rotatably connected to the rear side of the fixing box 31. The output shaft of the second motor 32 is fixed to the front end of the rotating drum 33. The input end of the second motor 32 is electrically connected to the output end of an external control switch group. The embossing assembly 4 includes a retaining strip 41 and an embossing ring 42. The rotating drum 33 has a circumferential surface. The rotating drum 33 has three corresponding slots, with locking strips 41 engaged inside each slot. An embossed ring 42 is fitted onto the circumference of the rotating drum 33, and all three locking strips 41 are fixed inside the embossed ring 42. The fixing assembly 5 includes a locking plate 51, a connecting strip 52, and springs 53. The rotating drum 33 has three corresponding slots inside, with locking plates 51 slidably connected inside each slot. The locking strips 41 have slots on their sides, and the locking plates 51 engage with the corresponding slots. Connecting strips 52 are fixed to the side of the locking plates 51 inside the rotating drum 33, and two corresponding springs 53 are fixed to the side of the connecting strips 52. All springs 53 are fixed inside two rotating drums 33 respectively. The extrusion assembly 6 includes... The device includes an internal threaded ring 61, a threaded post 62, a pressing cone 63, and a turntable 64. The internal threaded ring 61 is fixed at the rear end inside the rotating drum 33. The internal threaded ring 61 is connected to the threaded post 62 by its internal thread. The pressing cone 63 is fixed at the front end of the threaded post 62. The pressing cone 63 is located between three corresponding connecting strips 52. The rear end of the threaded post 62 is fixed. The pressing cone 63 is used to press the three corresponding connecting strips 52. The embossing component 4 is fixed by the fixing component 5. The embossing component 4 is used to emboss the paper. The embossing component 4 is driven to rotate by the rotating component 3. The spacing between the two rotating drums 33 is adjusted by the adjusting component 2. Among them, the input terminals of the first motor 23 and the belt conveyor 7 are both electrically connected to the output terminals of an external control switch group.
[0015] The working principle of the adjustable gap planar embossing conveyor mechanism provided by this utility model is as follows: When in use, the first motor 23 can be started to drive the bidirectional screw 25 to rotate as needed. Since the threads at both ends of the bidirectional screw 25 are opposite, the two moving frames 24 are driven to move synchronously in opposite directions within the mounting box 21, thereby precisely adjusting the horizontal distance between the two rotating drums 33 to adapt to different paper thicknesses. When the paper is conveyed to the embossing area by the belt conveyor 7, the second motor 32 of the rotating component 3 drives the rotating drum 33 to rotate. The two rotating drums 33 rotate in opposite directions. In this case, the embossing ring 42 sleeved on the rotating drum 33 can be driven to emboss the paper. The embossing ring 42 is fixed to the strip groove of the rotating drum 33 by the three internal locking strips 41. The spring 53 of the fixing component 5 pushes the connecting bar 52 and the clamping plate 51 outward, so that the clamping plate 51 is embedded in the groove on the side of the clamping bar 41 to achieve initial locking. When it is necessary to replace the embossing ring 42, operate the extrusion component 6: rotate the turntable 64 at the rear end of the threaded column 62, so that the threaded column 62 moves backward along the inner threaded ring 61, driving the extrusion cone 63 to disengage from the extrusion of the connecting bar 52. The spring 53 retracts and pulls the clamping plate 51 out of the groove, so that the embossing ring 42 can be removed. After installing the new embossing ring 42, rotate the turntable 64 in the opposite direction. The extrusion cone 63 moves forward and weds into the three connecting bars 52, forcing the connecting bars 52 to expand radially. This drives the clamping plate 51 to re-clamp into the groove of the clamping bar 41 to fix the clamping bar 41. After fixing, the embossing can be performed again.
[0016] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with buttons corresponding to the first motor 23, the second motor 32 and the belt conveyor 7. The first motor 23, the second motor 32 and the belt conveyor 7 can be freely configured according to the actual application scenario. The external control switch group controls the operation of the first motor 23, the second motor 32 and the belt conveyor 7 using methods commonly used in the prior art.
