Description

Technical Field

[0001] This utility model relates to the field of sporting goods technology, specifically to a positioning and pressing mechanism for curved water transfer printing film for sporting goods. Background Technology

[0002] Sporting goods refer to a general term for various equipment, gear, and supplies specifically designed for use in sports. During the design and manufacturing process, these sporting goods often need to consider the needs of athletes, the characteristics of the sport, and the durability and safety of the product. In this utility model, we pay particular attention to the positioning and pressing mechanism of the water transfer printing film on curved surfaces of sporting goods. This mechanism is designed to improve the adhesion and stability of the water transfer printing film on the curved surfaces of sporting goods, thereby ensuring the aesthetic appeal and durability of the sporting goods.

[0003] According to patent document CN216969028U, a water transfer printing laminating device is disclosed, including a water tank with a drain outlet on one side. Fixed frames are fixedly connected to both ends of the top of the water tank, and a device pipe is fixedly connected between the two fixed frames. A motor is fixedly connected to the side of the fixed frame away from the device pipe. The motor drive shaft passes through the fixed frame and is fixedly connected to a lead screw. A slider is threaded onto the outer wall of the lead screw, and mounting frames are fixedly connected to both ends of the bottom of the slider. A cleaning component is arranged between the two mounting frames. This invention utilizes the cooperation between the motor, lead screw, slider, and cleaning component. The motor drives the lead screw to rotate, causing the movable frame and movable plate in the cleaning component to move inside the water tank. This allows residual transfer printing paper to be adsorbed and adhered to the movable frame and movable plate, thereby achieving rapid cleaning of the transfer printing water tank without manual cleaning, saving a significant amount of time and manpower, and facilitating better laminating of the next workpiece.

[0004] In the manufacturing of some rackets, a film is often applied to the racket to enhance its appearance. The traditional method involves placing the water transfer film in a water tank and then manually immersing the part of the racket to be printed into the water to allow the film to adhere to the racket surface. However, this method is not only inefficient, but the printing effect is also often difficult to guarantee, as it is hard to achieve a complete adhesion by manually pressing the film onto the racket.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2 This utility model provides a technical solution: including a water tank 1, with a membrane track plate 2 movably connected to the top of the water tank 1, and a pressure boosting mechanism 3 fixedly connected to the top left side of the membrane track plate 2.

[0024] Please see Figure 2-4 The water tank 1 includes a main body 11. A concave support block 12 is fixedly connected to the middle of the left side of the top of the main body 11. Side plates 13 are fixedly connected to the front and rear sides of the right side of the top of the main body 11. Connecting plates 14 are fixedly connected to the top and bottom of the inner sides of the two side plates 13. A core plate 15 is fixedly connected to the inner side of the two sets of connecting plates 14. A second concave support block 16 is fixedly connected to the left side of the core plate 15. A hydraulic push rod 17 is fixedly connected to the right side of the core plate 15. A bidirectional hinge block 18 is rotatably connected to the top of the hydraulic push rod 17. The membrane track plate 2 includes a main body 21. A concave support block 12 is fixedly connected to the top right side of the top of the concave support block 12. An inverted L-shaped rotating rod 22 is rotatably connected to the inner side of the shaft plate 15 at the middle of its right side. An inverted L-shaped rotating rod hinge block 23 is fixedly connected to the right side of the inverted L-shaped rotating rod 22. The outer wall of the inverted L-shaped rotating rod hinge block 23 is rotatably connected to the top of the inner side of the bidirectional hinge block 18.

The outer wall of the positioning block 24 is movably connected to the inner side of the concave support block 12.

[0025] When water transfer printing is needed on the curved surface of the racket, first, the racket handle is fixed to the bottom of the lifting mechanism 3. Then, the hydraulic push rod 17 is activated. The hydraulic push rod 17 pushes the bidirectional hinge block 18 to move. The bidirectional hinge block 18 drives the inverted L-shaped rotating rod hinge block 23 to move. The inverted L-shaped rotating rod hinge block 23 drives the membrane track plate body 21 to flip through the inverted L-shaped rotating rod 22. When the membrane track plate body 21 flips to above the water tank 1, the hydraulic push rod 17 stops working. At this time, the curved groove 27 on the racket shaft of the membrane track plate body 21 fits against the curved surface of the racket. Then, the water transfer printing is carried out by the lifting mechanism 3. The pressing mechanism 3 presses the curved surface of the racket onto the water transfer film. At the same time, the concave support block 12 and the positioning block 24 cooperate to limit the position of the main body 21 of the film track plate, ensuring the stability of the main body 21 of the film track plate during the flipping process. After pressing, the curved surface of the racket is evenly covered with the water transfer film. Then, the pressure is slowly released by the pressure-raising mechanism 3 to remove the racket from the water transfer film, completing the entire water transfer process. The hydraulic push rod 17 is activated again to drive the main body 21 of the film track plate to flip back to its original position, making it convenient to remove the racket and place a new racket for film printing.

The inner wall of the guide rod 32 is slidably connected with a semi-circular rack rod 38. The inner sides of the front and rear sets of semi-circular rack rods 38 are meshed with the outer walls of the two sets of gears 37. The top of the front and rear sets of semi-circular rack rods 38 is fixedly connected with a lifting rod connecting block 39. The inner wall of the two lifting rod connecting blocks 39 is fixedly connected with a lifting rod 310. The bottom end of the two lifting rods 310 extends to the bottom of the outer wall of the control plate 31, and the outer wall of each lifting rod is fixedly connected with a guide ring inner guide tube 3112. The bottom of the two guide ring inner guide tubes 3112 is fixedly connected with a lever clamping plate 317.

A second hydraulic push rod 319 is fixedly connected to the inner side of the two racket handle clamping discs 317. The top of the second hydraulic push rod 319 is fixed to the middle part of the bottom of the push-pull crossbar 318. V-shaped rotating rods 3110 are rotatably connected to the middle of the left and right sides of the two racket handle clamping discs 317. The top inner sides of the two sets of V-shaped rotating rods 3110 are rotatably connected to the outer walls of the two lifting collars 3111. Racket handle clamping plates 3113 are rotatably connected to the left and right sides of the bottom of the two racket handle clamping discs 317. The outer sides of the two sets of racket handle clamping plates 3113 are rotatably connected to the bottom inner sides of the two sets of V-shaped rotating rods 3110. C-shaped connecting plates 311 are fixedly connected to the four sides of the control plate 31. Two sets of C-shaped connecting plates are also fixedly connected to the left and right sides. The inner side of the outer side of the connecting plate 311 is fixedly connected with columnar uprights 312. The bottom of the outer side of the left and right C-shaped connecting plates 311 is fixedly connected with support uprights 315.

[0027] When it is necessary to secure the racket, first place the racket handle inside the two shaft clamping plates 3113 at the bottom of the two shaft clamping discs 317. Then, activate the second hydraulic push rod 319, which drives the shaft clamping discs 317 to rise and fall. The shaft clamping discs 317 clamp and secure the racket through the cooperation of the V-shaped rotating rod 3110 and the shaft clamping plates 3113. Simultaneously, activate the dual-axis motor 33, which drives the two bevel gears 34 to rotate. The two bevel gears 34 drive the two second bevel gears 35 to rotate, which in turn drive the two gear rods 36 to rotate. The two gear rods 36 then drive the two sets of gears 37 to move forward. As the racket rotates, two sets of gears 37 drive two sets of semi-circular rack rods 38 to slide on the inner wall of the semi-circular guide rod 32. The two sets of semi-circular rack rods 38 drive two lifting rod connecting blocks 39 to rise and fall. The two lifting rod connecting blocks 39 drive two lifting rods 310 and two guide ring inner tubes 3112 to rise and fall. The two guide ring inner tubes 3112 drive two racket shaft clamping plates 317 and two rackets to rise and fall, thus realizing the raising and lowering operation of the rackets. At the same time, the T-shaped slider 314 slides on the inner wall of the C-shaped connecting plate guide groove 313 to guide the raising and lowering process of the racket shaft clamping plate 317, ensuring the stability of the racket shaft clamping plate 317 during the raising and lowering process.

[0028] Working principle: When water transfer printing is required on the curved surface of a racket, the racket handle is first fixed to the bottom of the pressure-lifting mechanism 3. Then, the hydraulic push rod 17 is activated, which pushes the bidirectional hinge block 18 to move. The bidirectional hinge block 18 drives the inverted L-shaped rotating rod hinge block 23 to move. The inverted L-shaped rotating rod hinge block 23 drives the membrane track plate body 21 to flip through the inverted L-shaped rotating rod 22. When the membrane track plate body 21 flips to above the water tank 1, the hydraulic push rod 17 stops working. At this time, the curved groove 27 on the racket shaft of the membrane track plate body 21 fits against the curved surface of the racket. The pressure-boosting mechanism 3 presses the curved surface of the racket onto the water transfer film. At the same time, the concave support block 12 and the positioning block 24 work together to limit the position of the main body 21 of the film track plate, ensuring the stability of the main body 21 of the film track plate during the flipping process. After pressing, the curved surface of the racket is evenly covered with the water transfer film. Then, the pressure is slowly released by the pressure-boosting mechanism 3 to remove the racket from the water transfer film, completing the entire water transfer process. The hydraulic push rod 17 is activated again to drive the main body 21 of the film track plate to flip back to its original position, making it convenient to remove the racket and place a new racket for film printing.

[0029] When it is necessary to secure the racket, first place the racket handle inside the two shaft clamping plates 3113 at the bottom of the two shaft clamping discs 317. Then, activate the second hydraulic push rod 319, which drives the shaft clamping discs 317 to rise and fall. The shaft clamping discs 317 clamp and secure the racket through the cooperation of the V-shaped rotating rod 3110 and the shaft clamping plates 3113. Simultaneously, activate the dual-axis motor 33, which drives the two bevel gears 34 to rotate. The two bevel gears 34 drive the two second bevel gears 35 to rotate, and the two second bevel gears 35 drive the two gear rods 36 to rotate. The rotation of the two gear rods 36 drives the two sets of gears 37 to rotate. The two sets of gears 37 drive the two sets of semi-circular rack rods 38 to slide on the inner wall of the semi-circular guide rod 32. The two sets of semi-circular rack rods 38 drive the two lifting rod connecting blocks 39 to rise and fall. The two lifting rod connecting blocks 39 drive the two lifting rods 310 and the two guide ring inner guide tubes 3112 to rise and fall. The two guide ring inner guide tubes 3112 drive the two racket clamping plates 317 and the two rackets to rise and fall, thereby realizing the raising and lowering operation of the rackets. At the same time, the T-shaped slider 314 slides on the inner wall of the C-shaped connecting plate guide groove 313.
