Description

Technical Field

[0001] This utility model relates to the field of card pressing machine technology, and in particular to a rotatable PVC card pressing machine. Background Technology

[0002] A card embossing machine is a device used to make cards with specific shapes and patterns. There are various types of card embossing machines, including manual and automatic ones. Manual embossing machines are usually smaller and suitable for personal or small-batch use, while automatic embossing machines are more efficient and suitable for large-scale production. The working principle of a card embossing machine is mainly to press the material with a mold. When the embossing machine is working, the mold applies downward pressure to press the material into a specific shape.

[0003] Traditional PVC card molding machines require a fixed mold and sequential mold opening, closing, and demolding processes. These steps are executed sequentially, resulting in a long operation cycle and reduced processing efficiency. Furthermore, manual mold disassembly and maintenance take a long time, and the equipment idles during mold changes, leading to significant resource waste. Therefore, a rotatable PVC card molding machine is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotatable PVC card molding machine to solve the problems mentioned in the background section.

The front side is provided with a guide groove 322 that matches the movement trajectory of the guide block 321. A guide post 323 that passes through the guide block 321 is fixedly installed between the upper and lower sides of the inner wall of the guide groove 322. A pressure mold 33 is installed at the bottom of the pressure plate 32 by bolts. A guide sleeve rod 34 located on both sides of the electric push rod 31 is movably installed between the pressure plate 32 and the inner top wall of the support base 2. The guide sleeve rod 34 constrains the vertical movement trajectory of the pressure plate 32 to prevent swaying. The guide block 321 on the rear side of the pressure plate 32 slides along the guide groove 322 of the support base 2, and works with the guide post 323 to further ensure the vertical alignment of the pressure mold 33.

[0029] A rotary table 4 is movably mounted on the top of the workbench 1 and located in front of the support base 2. A slip ring 41 is fixedly mounted on the bottom of the rotary table 4. A slide rail 42, which is fixedly connected to the workbench 1, is slidably mounted inside the slip ring 41. Several limit grooves 43 are provided on the top of the rotary table 4 and are distributed in a ring at equal intervals. The sliding cooperation between the slip ring 41 and the slide rail 42 ensures that the rotary table 4 rotates smoothly.

[0030] A lower mold assembly 5 is movably mounted on the top of the rotary table 4. The rotary table 4 supports the lower mold assembly 5, realizing the function of rotating and switching workstations. The lower mold assembly 5 includes several mold bases 51. The mold bases 51 are movably mounted on the rotary table 4 and distributed on several limiting grooves 43. A lower mold 52 is fixedly mounted inside the mold base 51.

The two bevel gears 64 mesh with each other. The two sets of meshing gears convert the horizontal rotational power into the horizontal rotational motion of the rotary table 4. This rotatable PVC card pressing machine drives the rotary table 4 to rotate through the control mechanism 6. The rotary table 4 then drives several lower mold components 5 on its top to rotate and adjust, so that the card can be pressed in the mold and then demolded, while the pressing process is carried out simultaneously, enabling continuous production.

[0032] The rotary table 4 is internally fitted with a limiting component 7 that extends outward and engages with the lower mold assembly 5. The limiting component 7 includes several bidirectional screws 71, each rotatably mounted within several limiting grooves 43 and extending to the outer side of the rotary table 4. A rotating block 72 is fixedly mounted at one end of each bidirectional screw 71 located on the outer side of the rotary table 4. The rotating block 72 allows for manual control of rotation by the user. Two threaded blocks 73 are threaded onto the outer side of each bidirectional screw 71. The limiting grooves 43 are internally fitted with a limiting component that extends into the recess 54 and... The limiting plates 74 are located on both sides of the bidirectional screw 71. An inclined push-pull rod 75 is rotatably installed between the limiting plates 74 and the threaded block 73. Two positioning pins 76 are fixedly installed on the side of the limiting plates 74 near the engaging hole 55, extending into it. The engagement hole 55 and the positioning pins 76 cooperate to limit the lower mold assembly 5, so that the lower mold assembly 5 can be quickly fixed and locked. When the user needs to disassemble, repair and maintain this rotatable PVC card molding machine, the lower mold assembly 5 can be quickly disassembled and assembled through the limiting assembly 7, which effectively reduces the downtime of the equipment and avoids the waste of idle running of the equipment.

[0033] The working process of this utility model:

[0034] Step 1: By controlling the motor 63 to drive the bevel gear 64 to mesh and transmit, the rotating shaft 62 rotates, thereby driving the rotating table 4 to rotate horizontally. The rotating table 4 then drives the lower mold 52 on the lower mold assembly 5 to rotate directly below the pressure mold 33.

[0035] Step 2: After the rotary table 4 rotates to the specified angle, the electric push rod 31 drives the pressure plate 32 to press down vertically. The pressure mold 33 and the lower mold 52 close to form a cavity. The positioning pin 53 and the positioning groove 531 cooperate to ensure the mold is aligned. After pressing is completed, the electric push rod 31 drives the pressure plate 32 to reset. At this time, the rotary table 4 is controlled to rotate again, so that the mold that has not been pressed can be pressed. The lower mold 52 that has been pressed can drive the formed card to perform demolding and other operations.

[0036] Step 3: When the rotating block 72 drives the bidirectional screw 71, the threaded block 73 drives the limiting plate 74 to move through the push-pull rod 75, so that the positioning pin 76 can be moved out of the locking hole 55, thus realizing the quick disassembly of the lower mold assembly 5. Conversely, it can be used for quick positioning and fixing.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
