Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper card cutting technology, and in particular to a paper card cutting device with edge and corner polishing function. Background Technology
[0002] Paper cards are flat items with a specific shape, purpose, and function, made primarily of paper. They are typically made from cardstock, coated paper, white cardstock, or specialty paper, and are generally rectangular—the most common and practical shape, easy to make, store, and use. However, some paper cards are designed in other shapes to meet special needs, such as circles, triangles, hearts, polygons, or other irregular shapes, or feature special cuts or perforations to increase their interest and uniqueness. Cutting devices are used in mass production processes.
[0003] In the current field of paper card cutting, traditional cutting equipment has many limitations. On the one hand, traditional cutting equipment is single-function, only capable of cutting cards. If the cut cards require edge finishing, additional equipment or manual labor is needed for sanding, increasing subsequent processing costs, including equipment purchase, maintenance, and labor expenses. On the other hand, if manual sanding is used, different operators' techniques and pressure can lead to inconsistent sanding results, affecting the overall quality and aesthetics of the product. Furthermore, if machine sanding is used, traditional equipment still requires transporting the cut cards to a designated location, a process that consumes more time and manpower, resulting in low production efficiency. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a paper card cutting device with edge and corner polishing function.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a paper card cutting device with edge grinding function, comprising: a machine tool, a table fixedly installed on the upper end of the machine tool, positioning plates respectively engaged on both sides of the upper middle part of the table, limit posts fixedly installed around the upper circumference of the positioning plates, a cross-shaped insert rod one fixedly installed on one side of the upper end of the table, a cross-shaped insert rod two fixedly installed through the table on the other side of the upper end of the table, and a cross-shaped slot provided at the lower end of each positioning plate, the cross-shaped slot and the cross-shaped insert rod two... The tabletop is connected to the cross-shaped insert rod one. A mounting groove is provided in the middle of the other end of the tabletop. A grooved wheel is fixedly installed on one side of the middle of the mounting groove. The upper end of the grooved wheel is fixedly connected to the cross-shaped insert rod two. Guide grooves are provided around the grooved wheel. A motor is fixedly installed on the other side of the middle of the mounting groove. A transmission plate is fixedly installed on the output end of the motor. A pin is fixedly installed on one side of the upper end of the transmission plate. The pin is slidably engaged with the guide groove. Grinding components are fixedly installed at the two corners of the positioning plate that is connected to the cross-shaped insert rod two.
[0006] In a preferred embodiment, each positioning plate has four limiting posts at its upper end, wherein a guide hole is provided in the middle of every three limiting posts, and a screw hole is provided in the middle of the other limiting post.
[0007] In a preferred embodiment, the upper end of the positioning plate is provided with a cross pressure plate, and guide rods are fixedly installed below the three ends of the cross pressure plate. A screw is threadedly connected to the middle of the other end of the cross pressure plate.
[0008] In a preferred embodiment, the guide rod is inserted into the guide hole, and the screw is threaded into the screw hole.
[0009] In a preferred embodiment, the cross pressure plate is connected to the screw and positioning plate via a guide rod, and handles are fixedly installed on both sides of the upper middle part of the cross pressure plate.
[0010] In a preferred embodiment, a bracket is fixedly installed on the upper end of the tabletop, and a controller is fixedly installed on one end of the bracket.
[0011] In a preferred embodiment, a cylinder is fixedly installed on one side of the lower middle part of the bracket, and a cutting tool is fixedly installed on the output end of the cylinder. The cutting tool is located directly above the positioning plate at the bottom, which is connected to the cross-shaped insert.
[0012] In a preferred embodiment, lighting lamps are fixedly installed at the four corners of the lower end of the bracket.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In use, the two sets of grinding components are located diagonally opposite the positioning plate, and work in conjunction with the intermittent rotation of the grooved wheel. This allows the four corners of the paper card to be ground by rotating the grooved wheel half a turn. At the same time, the intermittent transmission allows the paper card to move rhythmically, ensuring that each corner is fully and consistently ground, greatly improving the grinding quality. More paper cards can be ground in the same unit of time, significantly improving production efficiency.
[0015] 2. In use, the positioning plate of this utility model is designed to be directly replaceable. Before and after the paper card is cut, the positioning plate can be quickly replaced and the paper card can be clamped and fixed by the insertion of the cross rod into the positioning plate, as well as the cooperation of the guide hole and screw hole on the cross pressure plate, guide rod, screw and limit post. This prevents the paper card from shifting during the processing, and the operation is simple, reducing labor intensity and improving the overall processing efficiency.
[0016] 3. When in use, the lights at the four corners of the lower end of the bracket can provide sufficient light, making it easy for operators to clearly observe the processing situation, make timely adjustments, ensure processing accuracy and quality, and also improve operational safety.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0029] Example 1: As Figure 1-4 As shown, this utility model provides a technical solution: a paper card cutting device with edge grinding function, comprising: a machine tool 1, a table 2 fixedly installed on the upper end of the machine tool 1, positioning plates 22 respectively clamped on both sides of the middle of the upper end of the table 2, limit posts 33 fixedly installed around the upper end of the positioning plates 22, a cross-shaped insert rod 21 fixedly installed on one side of the upper end of the table 2, a cross-shaped insert rod 24 fixedly installed through the table 2 on the other side of the upper end of the table 2, and a cross-shaped slot 32 opened at the lower end of the positioning plates 22, the cross-shaped slot 32, the cross-shaped insert rod 24, and the cross-shaped insert rod 21. The two sides are connected by an interlocking mechanism. A mounting groove 20 is provided in the middle of the other end of the tabletop 2. A grooved wheel 27 is fixedly installed on one side of the middle of the mounting groove 20. The upper end of the grooved wheel 27 is fixedly connected to the cross-shaped insert rod 24. Guide grooves 28 are provided around the grooved wheel 27. A motor 31 is fixedly installed on the other side of the middle of the mounting groove 20. A transmission plate 29 is fixedly installed on the output end of the motor 31. A pin 30 is fixedly installed on one side of the upper end of the transmission plate 29. The pin 30 is slidably engaged with the guide groove 28. Grinding components 25 are fixedly installed at the two corners of the positioning plate 22 that is connected to the cross-shaped insert rod 24.
[0030] In this embodiment, the positioning plate 22 adopts a replaceable design. One of the positioning plates 22 is used to hold the paper card before cutting. After cutting, the user can directly insert it into the upper end of the bracket 11, where the cross-shaped insert rod 24 is installed on the other side. The cross-shaped pressure plate 36 is connected to the screw hole 35 on the upper part of the positioning plate 22 through the handle 39 to press the cut paper card tightly, preventing the paper card from shifting during subsequent processing and causing uneven sanding. Then, the motor 31 is started to drive the transmission plate 29 to rotate. The pin 30 on the transmission plate 29 slides and engages with the guide groove 28 of the grooved wheel 27. The precise intermittent rotation and intermittent transmission method allow the paper cards to move intermittently according to a set rhythm, enabling the polishing component 25 to polish the edges and corners of the paper cards sequentially. This ensures that each edge and corner receives thorough and consistent polishing, effectively improving polishing quality. The polishing component 25 has two sets, which are fixed diagonally at the positioning plate 22. The polishing component consists of two rotating wheels and a polishing belt for transmission. This allows the grooved wheel 27 to polish the four corners of the paper card by rotating half a turn, meaning that more paper cards can be polished per unit time, greatly improving production efficiency.
[0031] Example 2: As Figure 1-3 As shown, each positioning plate 22 has four limiting posts 33 at its upper end. A guide hole 34 is provided in the middle of every three limiting posts 33, and a screw hole 35 is provided in the middle of the other limiting post 33. A cross-shaped pressure plate 36 is provided at the upper end of the positioning plate 22. Guide rods 37 are fixedly installed below the three ends of the cross-shaped pressure plate 36. A screw rod 38 is threadedly connected to the middle of the other end of the cross-shaped pressure plate 36. The guide rod 37 is inserted into the guide hole 34, and the screw rod 38 is threadedly connected to the screw hole 35. The cross-shaped pressure plate 36 is connected to the guide rods... 37 is connected to screw 38 and positioning plate 22. Handles 39 are fixedly installed on both sides of the upper middle part of cross pressure plate 36. A bracket 11 is fixedly installed on the upper end of table 2. A controller 12 is fixedly installed on one end of bracket 11. A cylinder 14 is fixedly installed on one side of the lower middle part of bracket 11. A cutting tool 15 is fixedly installed on the output end of cylinder 14. The cutting tool 15 is located directly above the positioning plate 22, which is inserted into the cross insertion rod 21 at the bottom. Lighting lamps 13 are fixedly installed at the four corners of the lower end of bracket 11.
[0032] In this embodiment, the paper card material to be processed is placed on the positioning plate 22 and positioned by the four upper limit posts 33. Then, the operator can precisely control the motor 31, cylinder 14 and other equipment through the controller 12. The control cylinder 14 drives the cutting tool 15 to move down, which can accurately cut the paper card. After cutting, the positioning plate 22 is connected to the cross pressure plate 36 and the cross pressure plate 36 through the cross pressure plate 36, the guide rod 37, the screw 38 and the guide hole 34 and screw hole 35 on the limit post 33, and the cut paper card is pressed tightly. Then, the entire positioning plate 22 is removed from the cross insertion rod 1 21 and installed on the cross insertion rod 2 24 for the next processing step by the handle 39. The lighting lamps 13 installed at the four corners of the lower end of the bracket 11 can provide sufficient light for the processing area, so that the operator can clearly observe the processing of the paper card, find problems in time and make adjustments. Good lighting conditions help improve processing accuracy and quality, and at the same time ensure the safety of the operator.
[0033] like Figure 1-4 As shown,
[0034] In operation, the paper card material to be processed is first placed on one of the positioning plates 22. The paper card is positioned using the four limiting posts 33 around the upper part of the positioning plate 22. Then, the operator can precisely control the cylinder 14 to move the cutting blade 15 downward through the controller 12. Since the cutting blade 15 is located directly above the positioning plate 22, which is connected to the cross rod 21 at the bottom, it can accurately cut the positioned paper card. After cutting, the cross pressure plate 36, guide rod 37, and screw 38 are used to cut the paper card. The positioning plate 22 is connected to the cross plate 36 and pressed tightly with the guide hole 34 and screw hole 35 on the limiting post 33. The entire positioning plate 22 is then removed from the cross insert 21 and installed on the cross insert 24 for further processing via the handle 39. Subsequently, the motor 31 is started by the controller 12, which drives the transmission plate 29 to rotate. The pin 30 at the upper end of the transmission plate 29 slides and engages with the guide groove 28 around the grooved wheel 27, achieving precise intermittent rotation of the grooved wheel 27. The upper end of the grooved wheel 27 is fixedly connected to the cross-shaped insert 24, and the positioning plate 22 is also inserted into the cross-shaped insert 24. Therefore, the intermittent rotation of the grooved wheel 27 will drive the paper card to move intermittently according to the set rhythm. At this time, the two sets of polishing components 25, which are fixed at opposite corners of the positioning plate 22, will polish the four corners of the paper card in turn. The polishing component 25 consists of two rotating wheels and a polishing belt for transmission. The grooved wheel 27 only needs to rotate half a turn to complete the polishing of the four corners of the paper card, realizing efficient polishing. During the entire processing, the lighting lamps 13 installed at the four corners of the lower end of the bracket 11 provide sufficient light for the processing area, enabling the operator to clearly observe the processing of the paper card, find problems in time and make adjustments, ensure processing accuracy and quality, and ensure the safety of the operator. The operation of the entire device, including the rotation of the motor 31 and the extension and retraction of the cylinder 14, is precisely controlled by the controller 12. The operator can set relevant parameters and monitor the operating status of the equipment through the controller 12.

[0036] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
