Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, specifically to a positioning device for printing in paper cup production. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are shaped like cups. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can withstand temperatures above 90℃, even boiling water. Paper cups are characterized by safety, hygiene, lightness, and convenience. They can be used in public places, restaurants, and eateries and are disposable items.

[0003] Announcement No. CN217395984U discloses a positioning device for paper cup production and printing, including a base plate, a support frame, a first cylinder, a second cylinder, a rotary motor, and a turntable. The support frame is located on one side of the base plate, and the first cylinder is located on the inner top side of the support frame. The output end of the first cylinder is connected to a first connecting plate. A rotating column is located on the side of the first connecting plate away from the first cylinder. The rotating column is rotatably connected to the first connecting plate via a rotating shaft. A connecting column is fixedly connected to the end of the rotating column away from the first connecting plate, and a pressure plate is connected to the end of the connecting column away from the rotating column. A rotary motor is located on one side of the base plate below the pressure plate, and the drive shaft of the rotary motor is connected to the turntable. A placement plate is located on the side of the turntable near the pressure plate. This invention provides good fixing effect and eliminates the need for workers to manually rotate the paper cups, reducing the workload of workers.

[0004] Traditional paper cup production positioning devices mostly use fixed-size molds or clamps to fix paper cups. When faced with paper cups of different sizes, fixed-size positioning devices cannot adaptively adjust their clamping or support structures. For paper cups with smaller diameters, the positioning device is too large and cannot fit tightly against the surface of the paper cup, causing the paper cup to easily shift during the printing process, resulting in the printed pattern being misaligned. Therefore, a positioning device for paper cup production and printing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for printing in paper cup production, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A positioning device for paper cup production and printing includes a support leg, a support plate fixedly connected to the outer wall of the support leg, a paper cup disposed on the top of the support plate, and a positioning component for positioning paper cups of different sizes. The positioning component includes a fixed plate, the outer wall of the fixed plate being fixedly connected to the outer wall of the support leg, a rotating rod rotatably connected inside the fixed plate, a worm gear fixedly connected to the outer wall of the rotating rod, a fixed block fixedly connected to the top of the fixed plate, and a motor fixedly installed inside the fixed block.

[0008] The above technical solution involves the coordinated operation of a support plate, paper cup, fixed plate, rotating rod, worm gear, fixed block, and motor. The motor provides the power source for the entire positioning process. Through the connection between the rotating rod and the worm gear, the rotational motion of the motor can be transmitted, thereby achieving automated positioning of the paper cup, improving production efficiency, and adapting to the needs of fast and accurate positioning of paper cups of different sizes.

[0009] A further improvement of this utility model is that: a limiting block is fixedly connected to the top of the fixed disk, a worm gear is rotatably connected inside the limiting block, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and one end of the worm gear is fixedly connected to the output end of the motor.

[0010] The above technical solution utilizes a combination of a limiting block, a worm gear, and a motor. The meshing transmission structure of the worm gear and worm wheel is self-locking, ensuring that the rotating parts remain in their current position when the motor stops rotating. This prevents the positioning device from shifting due to external forces, guaranteeing the positioning accuracy of the paper cup during the printing process. Furthermore, this transmission method allows for a larger transmission ratio, enabling the low-speed rotation of the motor to be converted into an appropriate rotational speed for the rotating rod, facilitating precise control of the positioning action and improving the accuracy and reliability of the positioning.

[0011] A further improvement of the present invention is that: a rotating disk is fixedly connected to the outer wall of the rotating rod, an arc-shaped groove is provided inside the rotating disk, a sliding column is slidably connected inside the arc-shaped groove, and a linkage block is fixedly connected to the outer wall of the sliding column.

[0012] The above technical solution utilizes a rotating disk, an arc-shaped groove, a sliding column, and a linkage block. The rotating rod drives the rotating disk to rotate, and the arc-shaped groove on the rotating disk cooperates with the sliding column, allowing the sliding column to reciprocate along the trajectory of the arc-shaped groove. This, in turn, drives the linkage block to move, converting rotational motion into linear reciprocating motion. This ingeniously achieves the driving of the positioning block, automatically adjusting its position according to the size of the paper cup. It provides suitable positioning force for paper cups of different diameters, improving the versatility and adaptability of the positioning device.

[0013] A further improvement of this utility model is that: a connecting plate is fixedly connected to the outer wall of the support leg, a sliding groove is provided inside the connecting plate, a sliding rod is slidably connected inside the sliding groove, and the bottom of the sliding rod is fixedly connected to the top of the linkage block.

[0014] The above technical solution involves the cooperation of a connecting plate, a sliding groove, a sliding rod, and a linkage block. The sliding groove on the connecting plate and the sliding rod provide guidance for the movement of the positioning block, ensuring that the positioning block moves stably closer to or further away from the paper cup in the horizontal direction. This prevents the positioning block from shifting or shaking during movement, thus ensuring the accuracy and stability of the positioning.

[0015] A further improvement of this utility model is that: a connecting block is fixedly connected to the outer wall of the slide rod, a spring is fixedly connected inside the connecting block, a positioning block is fixedly connected to one side of the spring, and the inner wall of the positioning block is in contact with the outer wall of the paper cup.

[0016] The above technical solution involves the cooperation of a connecting block, a spring, a positioning block, and a paper cup. When the positioning block contacts the paper cup, the spring automatically adjusts the clamping force of the positioning block according to the actual size and shape of the paper cup. This ensures the stable fixation of the paper cup during the printing process, preventing displacement, and avoids damage to the paper cup due to excessive clamping. It is suitable for paper cups of different materials and thicknesses, further improving the applicability and reliability of the positioning device, and ensuring the integrity of the paper cup and the printing quality during the printing process.

[0017] A further improvement of this utility model is that: there are four sets of arc-shaped grooves and four sets of positioning blocks.

[0018] By adopting the above technical solution, the four sets of arc grooves and four sets of positioning blocks work together to enable the positioning device to uniformly position the paper cup from multiple directions, ensuring the force balance of the paper cup in the circumferential direction, avoiding uneven local force that could cause the paper cup to tilt or shift, and improving the stability of the paper cup during the printing process.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is that it can automatically adjust the position of the positioning block according to the size of the paper cup, and can provide a suitable positioning force for paper cups of different diameters, thereby improving the versatility and adaptability of the positioning device.

[0020] 1. This utility model provides a positioning device for paper cup production and printing. By setting a limit block, a worm gear and a motor in cooperation, the meshing transmission structure of the worm gear and worm wheel has self-locking property. When the motor stops rotating, it can keep the rotating parts in the current position, preventing the positioning device from being displaced by external force, and ensuring the positioning accuracy of the paper cup during the printing process. At the same time, this transmission method can achieve a large transmission ratio, so that the low speed of the motor can be converted into the appropriate speed of the rotating rod, which is convenient for precise control of the positioning action and improves the accuracy and reliability of positioning.

[0021] 2. This utility model provides a positioning device for paper cup production and printing. By setting up a rotating disk, an arc groove, a sliding column, and a linkage block in cooperation, the rotating rod drives the rotating disk to rotate. The arc groove on the rotating disk cooperates with the sliding column, so that the sliding column can reciprocate along the trajectory of the arc groove, thereby driving the linkage block to move. It can convert rotational motion into linear reciprocating motion, cleverly realizing the driving of the positioning block. It can automatically adjust the position of the positioning block according to the size of the paper cup, and provide appropriate positioning force for paper cups of different diameters, thus improving the versatility and adaptability of the positioning device.

[0022] 3. This utility model provides a positioning device for paper cup production and printing. By setting up a connecting block, a spring, a positioning block and a paper cup in cooperation, when the positioning block contacts the paper cup, the spring can automatically adjust the clamping force of the positioning block according to the actual size and shape of the paper cup. This ensures the stable fixation of the paper cup during the printing process and prevents its displacement, while also avoiding damage to the paper cup due to excessive clamping. It is suitable for paper cups of different materials and thicknesses, further improving the applicability and reliability of the positioning device, and ensuring the integrity of the paper cup and the printing quality during the printing process.

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-4 As shown, this utility model provides a positioning device for paper cup production and printing, including a support leg 1, a support plate 2 fixedly connected to the outer wall of the support leg 1, a paper cup 3 disposed on the top of the support plate 2, and a positioning component for positioning paper cups 3 of different sizes on the support plate 2. The positioning component includes a fixed plate 4, the outer wall of the fixed plate 4 is fixedly connected to the outer wall of the support leg 1, a rotating rod 5 is rotatably connected inside the fixed plate 4, a worm gear 6 is fixedly connected to the outer wall of the rotating rod 5, a fixed block 7 is fixedly connected to the top of the fixed plate 4, a motor 8 is fixedly installed inside the fixed block 7, a limit block 9 is fixedly connected to the top of the fixed plate 4, a worm 10 is rotatably connected inside the limit block 9, the outer wall of the worm 10 meshes with the outer wall of the worm gear 6, and one end of the worm 10 is fixedly connected to the output end of the motor 8.

[0031] In this embodiment, the support plate 2, paper cup 3, fixed plate 4, rotating rod 5, worm gear 6, fixed block 7, and motor 8 are arranged in a coordinated manner. The motor 8 provides the power source for the entire positioning process. Through the connection between the rotating rod 5 and the worm gear 6, the rotational motion of the motor 8 can be transmitted, realizing the automated positioning of the paper cup 3, improving production efficiency, and adapting to the needs of fast and accurate positioning of paper cups 3 of different sizes. Through the coordination of the limit block 9, worm gear 10, and motor 8, the meshing transmission structure of worm gear 10 and worm gear 6 has self-locking properties. When the motor 8 stops rotating, the rotating parts can be kept in the current position, preventing the positioning device from being displaced by external forces, ensuring the positioning accuracy of the paper cup 3 during the printing process. At the same time, this transmission method can achieve a large transmission ratio, so that the low-speed rotation of the motor 8 can be converted into the appropriate speed of the rotating rod 5, which facilitates precise control of the positioning action and improves the accuracy and reliability of positioning.

[0032] Example 2

[0033] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a rotating disk 11 is fixedly connected to the outer wall of the rotating rod 5, an arc-shaped groove 12 is provided inside the rotating disk 11, a sliding column 13 is slidably connected inside the arc-shaped groove 12, a linkage block 14 is fixedly connected to the outer wall of the sliding column 13, a connecting disk 15 is fixedly connected to the outer wall of the support leg 1, a sliding groove 16 is provided inside the connecting disk 15, a sliding rod 17 is slidably connected inside the sliding groove 16, the bottom of the sliding rod 17 is fixedly connected to the top of the linkage block 14, a connecting block 18 is fixedly connected to the outer wall of the sliding rod 17, a spring 19 is fixedly connected inside the connecting block 18, a positioning block 20 is fixedly connected to one side of the spring 19, the inner wall of the positioning block 20 contacts the outer wall of the paper cup 3, there are four sets of arc-shaped grooves 12, and four sets of positioning blocks 20.

[0034] In this embodiment, by setting up the mutual cooperation of the rotating disk 11, the arc groove 12, the sliding column 13, and the linkage block 14, the rotating rod 5 drives the rotating disk 11 to rotate. The arc groove 12 on the rotating disk 11 cooperates with the sliding column 13, so that the sliding column 13 can reciprocate along the trajectory of the arc groove 12, thereby driving the linkage block 14 to move. This can convert rotational motion into linear reciprocating motion, cleverly realizing the driving of the positioning block 20. It can automatically adjust the position of the positioning block 20 according to the size of the paper cup 3, and provide appropriate positioning force for paper cups 3 of different diameters, improving the versatility and adaptability of the positioning device. By setting up the mutual cooperation of the connecting disk 15, the sliding groove 16, the sliding rod 17, and the linkage block 14, the sliding cooperation between the sliding groove 16 on the connecting disk 15 and the sliding rod 17 provides a guiding effect for the movement of the positioning block 20, ensuring that the positioning block 20 stably approaches or moves away from the paper cup 3 in the horizontal direction, and avoiding the positioning block 20 from moving during the movement. The positioning device ensures accuracy and stability by mitigating offset or wobbling. Through the interaction of connecting block 18, spring 19, positioning block 20, and paper cup 3, when positioning block 20 contacts paper cup 3, spring 19 automatically adjusts the clamping force of positioning block 20 according to the actual size and shape of paper cup 3. This ensures the stable fixation of paper cup 3 during printing, preventing displacement, and avoids damage to paper cup 3 due to excessive clamping. It is suitable for paper cups 3 of different materials and thicknesses, further improving the applicability and reliability of the positioning device, ensuring the integrity and printing quality of paper cup 3 during printing. The interaction of arc groove 12 and positioning block 20, with four sets of arc grooves 12 and four sets of positioning blocks 20, allows the positioning device to uniformly position paper cup 3 from multiple directions, ensuring force balance in the circumferential direction and preventing uneven local force that could cause tilting or offset of paper cup 3, thus improving the stability of paper cup 3 during printing.

[0035] The working principle of the positioning device for printing paper cup 3 will be explained in detail below.

[0036] like Figure 1-4 As shown, during the paper cup 3 production and printing process, when positioning of the paper cup 3 is required, the motor 8 inside the fixing block 7 is activated. The output end of the motor 8 drives the worm gear 10 to rotate. Since the worm gear 10 meshes with the worm wheel 6 on the outer wall of the rotating rod 5 on the fixed disk 4, the rotation of the worm gear 10 drives the worm wheel 6 and the rotating rod 5 to rotate together. When the rotating rod 5 rotates, the rotating disk 11 on its outer wall also rotates accordingly. The arc groove 12 in the rotating disk 11 drives the sliding column 13 to perform reciprocating linear motion. The sliding column 13 drives the linkage block 14 to move synchronously. The movement of the linkage block 14 is achieved by the sliding rod 17, which is fixedly connected to it, sliding in the groove 16 of the connecting disk 15. Now, the connecting block 18 on the slide bar 17 and the spring 19 between the connecting block 18 and the positioning block 20 also move, eventually making the positioning block 20 contact the outer wall of the paper cup 3. The four sets of positioning blocks 20 are driven by the four sets of arc grooves 12 to position the paper cup 3 from different directions. The elasticity of the spring 19 ensures that the positioning block 20 can stably fix the paper cup 3 without excessive compression. In this way, the positioning device can automatically adjust the position and clamping force of the positioning block 20 according to the size of the paper cup 3, realize the accurate positioning of paper cups 3 of different sizes, provide a stable foundation for subsequent printing processes, and ensure the quality and efficiency of printing the paper cup 3.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
