Description

Technical Field

[0001] This utility model relates to the technical field of sheet surface treatment equipment, specifically to a sheet embossing machine. Background Technology

[0002] Embossing is a common decorative packaging material processing technique. Based on the embossing method, it is divided into flat embossing and roller embossing. Flat embossing machines operate on an intermittent molding process: the sheet is fixed to the lower die, the upper die moves downwards to close and apply pressure, and after embossing, the upper die rises back to remove the workpiece. This method produces high pressure and deep textures, but its production efficiency is low, with each embossing cycle including a significant amount of idle time. Roller embossing machines are a high-efficiency, continuous material surface treatment device. Their core structure includes a pair of parallel and relatively rotatable embossing rollers, one with the desired pattern and the other typically a smooth pressure roller. During operation, the roll of material to be processed passes through the pressure zone between the two rollers. Under certain temperature and pressure conditions, the texture on the pattern roller is transferred to the material surface, forming a permanent raised and recessed pattern.

[0003] Patent document CN113119527A discloses an embossing machine, including a support frame, a dual-station roller feeding mechanism, a heating device, an embossing device, and a dual-station roller take-up mechanism. This invention, by setting up a feeding support frame and a take-up support frame, enables dual-station operation of the feeding and take-up mechanisms. Whether feeding or taking up, the machine can switch between roll materials without stopping operation, greatly improving the machine's efficiency.

[0004] However, it can only perform roller embossing on continuous rolls and cannot perform roller embossing on multi-layer stacked sheets. In the existing technology, the processing of multi-layer stacked sheets is mostly done by flat embossing machines, which have low production efficiency and low degree of automation. Summary of the Invention

[0005] This invention aims to solve the technical problem that existing embossing machines cannot emboss multi-layered stacked sheets using rollers.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A sheet embossing machine is provided, comprising a frame, on which a feeding area, an embossing area, and a discharging area are sequentially arranged. A feeding mechanism is provided in the feeding area, an embossing mechanism is provided in the embossing area, and a sorting mechanism is provided in the discharging area. The feeding mechanism includes a picking component and a conveying component, which are arranged adjacent to each other on the frame. The embossing mechanism includes a steel sheet roller assembly and a rubber sheet roller assembly rotatably arranged parallel to each other on the frame, and the embossing mechanism is arranged adjacent to the conveying component. A power transmission component is also provided on the frame to drive the steel sheet roller assembly and the rubber sheet roller assembly to rotate. The sorting mechanism includes left and right correction components arranged opposite to each other on both sides of the frame and a rear sway blocking component located on one side of the left and right correction components. A transmission conveying component is provided on the frame, connecting the rubber sheet roller assembly and the sorting mechanism through the transmission conveying component, thereby driving the sorting mechanism to operate and conveying the sheet material in the embossing area to the discharging area.

[0007] This solution involves placing the sheet material from the feeding area onto the conveying component via a material handling assembly. The conveying component then transports the sheet material to the embossing area, where it is embossed by steel and rubber roller assemblies. After embossing, the sheet material is then transported to the discharge area via a transmission conveying assembly. In the discharge area, the sheet material is straightened by left and right correction and rear sway blocking components before being directly conveyed away. The entire process is highly automated, saving labor costs, and the embossing of the sheet material using rotating roller structures significantly improves efficiency. Attached Figure Description

Detailed Implementation

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0010] like Figures 1 to 7 As shown, a sheet embossing machine includes a frame 1, on which a feeding area 100, an embossing area 200 and an output area 300 are arranged in sequence. A feeding mechanism 10 is provided in the feeding area 100, an embossing mechanism 20 is provided in the embossing area 200, and a sorting mechanism 30 is provided in the output area 300.

[0011] The feeding mechanism 10 includes a picking component 101 and a conveying component 102, which are arranged adjacent to each other on the frame 1.

[0012] The embossing mechanism 20 includes a steel plate roller assembly 201 and a rubber roller assembly 202 that are rotatably mounted on the frame 1. The embossing mechanism 20 is arranged adjacent to the conveying assembly 102. A power transmission assembly 11 that drives the steel plate roller assembly 201 and the rubber roller assembly 202 to rotate is also provided on the frame 1.

[0013] The sorting mechanism 30 includes left and right correction components 301 arranged opposite to each other on both sides of the frame 1 and a rear sway blocking component 302 arranged on one side of the left and right correction components 301. A transmission conveying component 12 is provided on the frame 1. The transmission conveying component 12 connects the rubber roller assembly 202 and the sorting mechanism 30, thereby driving the sorting mechanism 30 to operate and conveying the sheet material in the embossing area 200 to the discharge area 300.

[0014] A first lifting assembly 103 is also provided in the feeding area 100. The first lifting assembly 103 is connected to a feeding plate 104. The feeding plate 104 is located below the picking assembly 101. In the initial state, the feeding plate 104 is flush with the ground. The sheet to be embossed is transported to the feeding plate 104. The first lifting assembly 103 pulls the feeding plate 104 up until the sheet can be picked up by the picking assembly 101. In this embodiment, the picking assembly 101 is a vacuum suction cup. The picking assembly 101 picks up the sheet and transfers it to the conveying assembly 102. As the sheet is continuously picked up and transferred to the conveying assembly 102, the first lifting assembly 103 continuously pulls the feeding plate 104 up, so that the sheet on the feeding plate 104 can be continuously picked up by the picking assembly 101.

[0015] The conveying assembly 102 includes a feed plate 1021. After the sheet is gripped by the picking assembly 101, it is placed on the feed plate 1021. Multiple feed belts 1022 are fitted on the feed plate 1021 and run on the feed plate 1021. Below the feed plate 1021, a tensioning assembly 1023 is provided to tighten the feed belts 1022. The tensioning assembly 1023 ensures that all feed belts 1022 have appropriate tension, prevents slippage between the belt and the drive roller, reduces belt vibration and abnormal wear, ensures smooth operation, and extends the service life of the belts and bearings. Multiple sets of pressure rollers 1024 are rotatably arranged above the feed belts 1022, increasing the effective traction force of the feed belts 1022 on the sheet and preventing the sheet from bouncing and drifting due to vibration or airflow.

[0016] A pressing roller 1025 is arranged parallel to and rotatably in front of the feed plate 1021. After the picking component 101 picks up the sheet, the sheet is placed on the pressing roller 1025. The pressing roller 1025 rotates to transport the sheet to the feed plate 1021. The movement of the picking component 101 is point-to-point. It needs to pick up the sheet from the stationary stockpile and move it to the conveyor line. If the sheet is placed directly on a high-speed conveyor belt, it will generate a huge inertial impact, causing the sheet to slip, misposition, or even tip over. The pressing roller 1025 plays an active handover role. It takes the sheet from the picking component 101 and then, through its own rotation, smoothly accelerates the sheet to a linear speed that matches the subsequent process before feeding it into the feed plate 1021, achieving a smooth transition from stationary to moving without impact.

[0017] like Figure 5 As shown, a feeding mechanism 40 is provided between the feed plate 1021 and the embossing mechanism 20. The feeding mechanism 40 includes a feeding pull gauge adjustment assembly 401, a feeding blocking shaft assembly 402, and a feeding deflection shaft adjustment assembly 403. The feeding blocking shaft assembly 402 is rotatably disposed above the feeding pull gauge adjustment assembly 401, and the feeding deflection shaft adjustment assembly 403 is rotatably disposed above the feeding blocking shaft assembly 402.

[0018] The sheet material is conveyed on the feed plate 1021 by the feed belt 1022 to the feed gauge adjustment assembly 401. It is then blocked and positioned by the feed blocking shaft assembly 402 at the edge of the feed gauge adjustment assembly 401 near the embossing mechanism 20. The feed gauge adjustment assembly 401 then finely adjusts the position of the sheet material to ensure that the side of the sheet material is parallel to the axis of the embossing roller. Subsequently, the feed deflection shaft adjustment assembly 403, located above the feed blocking shaft assembly 402, swings towards the sheet material to clamp the sheet material blocked by the feed blocking shaft assembly 402. The feed blocking shaft assembly 402 releases its obstruction of the sheet material. After clamping the sheet material, the feed deflection shaft adjustment assembly 403 swings towards the rubber roller assembly 202, placing the sheet material on the rubber roller assembly 202. The sheet material rotates with the rubber roller assembly 202 and is embossed by the pressing of the steel plate roller assembly 201 and the rubber roller assembly 202.

[0019] like Figure 7 and Figure 8 As shown, in this embodiment, both ends of the steel plate roller assembly 201 are connected to the left and right frames 1 respectively via bearing rings 203. The bearing ring 203 has an annular mounting portion 2031 and a flange portion 2032 connected to one end of the annular mounting portion 2031. The outer circumference of the annular mounting portion 2031 is clearance-fitted with the frame 1. An eccentric hole 2033 is provided inside the annular mounting portion 2031, and the steel plate roller assembly 201 is rotatably disposed in the eccentric hole 2033. An adjustment device 204 is provided on the frame 1 to allow the bearing ring 203 to rotate around the center of the outer circumference of the annular mounting portion 2031.

[0020] When the bearing ring 203 is rotated, the position of the axis of the steel sheet roller assembly 201 will change because the centers of the inner and outer circumferences of the bearing ring 203 do not coincide, thereby changing the gap width with the rubber sheet roller assembly 202. An adjustment device 204 for adjusting the posture of the bearing ring 203 is also provided on the frame 1. Controlling the adjustment device 204 can make the bearing ring 203 rotate around the center of the outer circumference of its annular mounting part 2031. When changing sheets of different thicknesses or different embossing depths, the operator can quickly and accurately adjust the roller gap, greatly reducing downtime for debugging.

[0021] like Figure 5 and Figure 6As shown, the power transmission assembly 11 includes a drive motor 111 and a transmission shaft assembly 112. The drive motor 111 drives the transmission shaft assembly 112 to rotate. A drive gear 113 is provided on one side of the transmission shaft assembly 112. The two ends of the rubber roller assembly 202 are respectively connected to the frame 1, and one end of the rubber roller assembly 202 is provided with a first driven gear 2021, which meshes with the drive gear 113. A second driven gear 2011 is provided at one end of the steel plate roller assembly 201, which meshes with the first driven gear 2021. The drive motor 111 drives the transmission shaft assembly 112 to rotate, and the drive gear 113 meshes with the first driven gear 2021, and the second driven gear 2011 meshes with the first driven gear 2021, thereby driving the steel plate roller assembly 201 and the rubber roller assembly 202 to rotate.

[0022] The transmission and conveying assembly 12 includes sprocket sets 121 fixed on the left and right sides of the frame 1. A drive shaft 122 is connected between the sprockets on the side near the rubber roller assembly 202. A drive chain 123 is connected between the sprockets in the sprocket sets 121. The connection between the sprockets in one sprocket set 121 and the rubber roller assembly 202 drives the transmission and conveying assembly 12 to rotate. Chain guide plates 13 are provided on both sides of the frame 1, and the drive chains 123 are movably mounted on the chain guide plates 13. Multiple sets of take-up teeth 124 are provided between the drive chains 123 on the left and right sides. The take-up teeth 124 move together with the drive chains 123 between the sprocket sets 121.

[0023] One sprocket in the sprocket assembly 121 of the transmission and conveying assembly 12 meshes with the first driven gear 2021 of the rubber roller assembly 202. This causes the rubber roller assembly 202, the steel plate roller assembly 201, and the transmission and conveying assembly 12 to move synchronously. After the sheet is pressed by the rubber roller assembly 202 and the steel plate roller assembly 201, it is picked up by the receiving tooth bar 124 and conveyed to the discharge area 300 via the transmission chain 123. The chain guide plate 13 provides reliable support and guidance for the chain, which greatly increases the rigidity and stability of the entire system, prevents the sheet from falling or shifting position during conveying due to chain vibration, and ensures a smooth conveying process.

[0024] like Figure 9As shown, the sorting mechanism also includes a stop cam 14 rotatably and relatively disposed on the left and right sides of the frame 1, the stop cam 14 being connected to the transmission and conveying assembly 12; the left and right correction assembly 301 includes a side push assembly 3011 disposed on the left and right sides of the frame 1, the side push assembly 3011 and the stop cam 14 abutting against a transmission assembly 303, and the transmission assembly 303 also abutting against a rear swing stop assembly 302, the stop cam 14 rotating to drive the transmission assembly 303, thereby driving the side push assembly 3011 and the rear swing stop assembly 302 to reciprocate; a receiving assembly 304 is disposed below the left and right correction assembly 301, the receiving assembly 304 including a second lifting assembly 3041 disposed on the left and right sides of the frame 1, the second lifting assembly 3041 being connected to a bearing plate 3042.

[0025] After the receiving jaws 124 clamp the sheet material to the discharge area 300, the sheet material is placed on the support plate 3042. Due to the rotation of the abutment cam 14, the transmission component 303 reciprocates. The side push component 3011, which abuts against the transmission component 303, is driven by the transmission component 303 to perform reciprocating linear motion, and the rear swing abutment component 302, which abuts against the transmission component 303, is driven by the transmission component 303 to perform reciprocating swing motion. The side push component 3011 is set on the left and right sides of the support plate 3042, and the rear swing abutment component 302 is set at the rear of the support plate 3042. The sheet material on the support plate 3042 is sorted by the side push component 3011 on the left and right sides and the rear swing abutment component 302 on the rear side. Then, the support plate 3042 is raised and lowered by the second lifting component 3041 to facilitate the continuous stacking of the sheet material on the support plate 3042, and also to facilitate the subsequent removal of the sheet material from the support plate 3042.

[0026] The above solution, through the cooperation of the feeding mechanism 10, the embossing mechanism 20 and the finishing mechanism 30, embosses multi-layer stacked sheets through rotating rollers, which greatly improves production efficiency. The whole process is highly automated, requires no excessive manual labor, and saves labor costs.
