Description

Technical Field

[0001] This utility model relates to the field of vacuum forming edge pressing technology, and more specifically, to a high-precision vacuum forming rapid edge pressing device. Background Technology

[0002] The high-precision thermoforming rapid edge-pressing device primarily utilizes a precise temperature control system and pressure regulation device to accurately control pressure parameters. This ensures that the sealing and edge-pressing effect of each product meets design requirements, enhancing the overall aesthetics and market competitiveness of the product.

[0003] Among the existing publicly available documents, patent publication number CN211843168U discloses a rapid vacuum forming device for plastic processing. This technology uses a conveyor belt and forming cavity to quickly process plastic sheets, forming a continuous operation. A hydraulic column and pressure plate cover tightly seal the forming cavity, improving the vacuum forming effect. An air pump, along with pipes, a heating plate, and a suction plate, quickly softens the plastic sheet and performs vacuum forming. A pressure device compresses the plastic sheet, and the suction plate further accelerates the product formation. However, this technology still has the following problems.

[0004] When using a high-precision thermoforming rapid edge pressing device, it is difficult to achieve large-area limited pressing at the edge during the pressing process. This can lead to either over-pressing or under-pressing, resulting in poor edge pressing accuracy of the thermoformed product. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a high-precision thermoforming rapid edge pressing device, comprising a sleeve support plate, an electric cylinder, and a push rod. The electric cylinder is fixed on the upper surface of the sleeve support plate, and the push rod is fixed at the output end of the electric cylinder. The push rod is slidably connected to the sleeve support plate, and an edge pressing precision limiting mechanism is installed at the bottom end of the push rod. The edge pressing precision limiting mechanism includes a connecting plate fixedly installed at the bottom end of the push rod. A frame plate is fixedly connected to one side of the connecting plate, and multiple connecting shafts are fixedly installed at the bottom end of the frame plate. An edge pressing strip is installed at the bottom end of the connecting shaft, and the multiple connecting shafts are fixedly connected to the edge pressing strip.

[0006] Both sides of the pressing strip are fixedly connected to pressure plates, and the bottom of each pressure plate is fixedly connected to multiple extrusion columns. Corner blocks are fixedly connected to the outer wall of the pressing strip and near its four corners. The bottom of each corner block is fixedly connected to a corner pressing column. A limiting frame is provided below the corner pressing column, and a pressing positioning seat is fixedly connected to the inner wall of the limiting frame.

[0007] Preferably, the multiple connecting shafts are arranged in a rectangular, equidistant distribution, and the cross-sectional shape of the connecting shafts is circular. A pressing groove is formed on the upper surface of the pressing edge positioning seat, and the pressing edge strip is inserted into the pressing edge positioning seat. Multiple extrusion columns are arranged equidistantly from left to right, and the bottom surface of the extrusion columns and the bottom surface of the corner pressing columns are on the same horizontal plane. The corner block has an L-shaped cross-section, and the pressure plate has a rectangular cross-section.

[0008] In use, the edge of the blister pack is attached to the upper surface of the pressing groove. The electric cylinder pushes the push rod downward, which in turn moves the connecting plate downward. The frame plate moves multiple connecting shafts downward synchronously, and the pressing strip moves multiple corner blocks downward. The corner pressing columns are pressed against the upper surface of the limiting frame strip. The pressure plate moves each of the multiple extrusion columns downward, and the multiple extrusion columns can press against the upper surface of the limiting frame strip. The limiting frame strip can precisely press the corner pressing columns and extrusion columns.

[0009] Preferably, the upper surface of the frame plate is provided with a guide assembly; the guide assembly includes two guide posts fixedly disposed on the upper surface of the frame plate, both guide posts being slidably connected to a sleeve support plate, a concave plate being installed at the top of each guide post, and a sliding ring being slidably connected to the outer wall of each guide post away from the concave plate, the sliding ring being slidably connected to the sleeve support plate; a sleeve slider is fixedly installed on one side of the inner wall of the concave plate, and a guide rod is slidably connected to the inner wall of the sleeve slider; a support block for supporting the guide rod is provided on one side of the sleeve support plate, and both the sleeve support plate and the guide rod are fixedly connected to the support block. The outer wall of the guide rod and the inner wall of the sleeve slider are both smooth surfaces, the cross-sectional shape of the guide rod is circular, and the cross-sectional shape of the support block is rectangular.

[0010] In use, the frame plate moves the two guide posts downwards, and the guide posts slide down along the inner wall of the sleeve support plate. The concave plate moves the sleeve slider downwards, and the sleeve slider slides down along the outer wall of the guide rod. The support block supports the guide rod, so that the downward movement of the frame plate can stably guide and press the edge.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This utility model utilizes a precise edge-pressing limiting mechanism. An electric cylinder pushes a push rod downwards, which moves along the inner wall of the sleeve support plate. The connecting plate then moves the frame plate downwards, and the edge-pressing strip moves multiple corner blocks downwards. These corner blocks then move corner pressing columns downwards. The limiting frame strip limits the multiple corner pressing columns, and the multiple extrusion columns can be pressed against the upper surface of the limiting frame strip. The limiting frame strip limits the corner pressing columns and extrusion columns, achieving precise edge-pressing and significantly improving edge-pressing accuracy.

[0013] 2. This utility model adopts a guide assembly. The frame plate drives two guide columns to move down. The guide columns slide down along the inner wall of the sleeve support plate, and the sleeve slider slides down along the outer wall of the guide rod. The guide rod provides guidance and support for the sleeve slider. The downward movement of the frame plate can stably guide and press the edge, making the pressing more stable.
