DETAILED DESCRIPTION

[0047] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0048] like Figures 1 to 5 As shown, the driving device for adjusting the casting speed of the utility model includes:

[0049] The speed regulating box 1 has a transmission cavity provided inside.

[0050] The input shaft 21 is rotatably mounted in the transmission cavity of the speed regulating box 1 and is used to input power;

[0051] The output shaft 22 is rotatably mounted in the transmission cavity of the speed regulating box 1 and is used to output power;

[0052] The drive disc 23 is rotatably disposed in the transmission cavity of the speed regulating box 1 and is driven to rotate by the input shaft 21. A plurality of chutes are arranged circumferentially on the drive disc 23.

[0053] The driven disc 24 is rotatably arranged in the transmission cavity of the speed regulating box 1 and is driven to rotate by the output shaft 22. A plurality of chutes are arranged circumferentially on the driven disc 24. The driven disc 24 and the driving disc 23 are driven by a belt.

[0054] Two linkage rings 25 are respectively slidably mounted on the input shaft 21 and the output shaft 22 and rotate on the input shaft 21 and the output shaft 22;

[0055] Multiple speed regulating components, the number of which is equal to the number of chutes of the driving disc 23 and the driven disc 24, and a speed regulating component is slidably arranged in each chute;

[0056] Control assembly, controlling the two linkage rings 25 to slide on the input shaft 21 and the output shaft 22;

[0057] Among them, the speed control components include:

[0058] The belt clamping block 201 is slidably arranged in the slide groove, and a clamping slot is provided on the belt clamping block 201 for clamping the belt;

[0059] The connecting block 202 is swingably mounted on the belt clamping block 201;

[0060] The hinge block 203 is hinged to the connecting block 202;

[0061] The hinged slide 204 is slidably arranged on the outer end surfaces of the driving plate 23 and the driven plate 24 and is hingedly matched with the hinge block 203;

[0062] The linkage rod 205 is hinged to the hinge block 203, and the outer end of the linkage rod 205 is ball-connected to the linkage ring 25;

[0063] The working process and principle of the device are as follows: when the throwing speed needs to be adjusted, the control component will drive the linkage ring 25 to slide on the input shaft 21 and the output shaft 22; the sliding of the linkage ring 25 will drive the movement of the linkage rod 205, and then push the belt clamping block 201 to slide in the slide groove through the hinge block 203 and the connecting block 202; the sliding of the belt clamping block 201 will change the effective transmission radius of the belt between the driving disc 23 and the driven disc 24, thereby realizing the adjustment of the throwing speed; since the belt clamping block 201 clamps the belt through the slot, it can ensure that the belt maintains stable transmission during the adjustment process; by adjusting the position of the linkage ring 25, To achieve continuous and stepless adjustment of the throwing speed to meet the needs of different product specifications; at the same time, the device can also make real-time adjustments according to dynamic changes in the production process to improve production efficiency and product quality; by changing the position of the belt clamp on the driving disc and the driven disc, that is, changing the diameter of the belt winding, thereby changing the transmission ratio from the driving disc to the driven disc, and finally achieving continuous and adjustable control of the throwing speed; not only overcomes the limitations of the traditional fixed transmission ratio, but also provides a more flexible and more accurate speed control solution, and also has the ability to respond quickly, which can complete speed adjustment in a short time, ensuring the efficient operation of the production line.

[0064] A limit block 26 is provided on each slide; the limit block 26 is provided on each slide, which can limit the sliding range of the belt clamp 201. If the belt clamp 201 attempts to exceed the limit of the limit block 26, the limit block 26 will provide resistance to prevent it from sliding further, thereby avoiding equipment damage or speed loss due to excessive adjustment and improving usage stability.

[0065] like Figures 2 to 3 As shown, the control components include:

[0066] The rotating rod 2a is vertically mounted in the speed regulating box 1;

[0067] The rotating sleeve 2b is fixedly mounted on the rotating rod 2a;

[0068] Four transmission clamps 2c are fixedly mounted on the rotating sleeve 2b, and transmission guide grooves are provided on the transmission clamps 2c;

[0069] Two shaft collars 2d are respectively slidably matched with the input shaft 21 and the output shaft 22, and the input shaft 21 and the output shaft 22 are both rotatably inserted into the shaft collars 2d, and the shaft collars 2d are fixedly connected to the linkage ring 25;

[0070] Transmission pin 2e, each shaft collar 2d is provided with two transmission pins 2e opposite to each other, and the transmission pin 2e is slidably provided in the transmission guide groove of the transmission splint 2c;

[0071] A locking assembly, provided on the rotating rod 2a, for locking the rotating rod 2a;

[0072] The working process and principle of the control component are as follows: when the throwing speed needs to be adjusted, the operator rotates the rotating rod 2a; since the rotating sleeve 2b is fixedly mounted on the turning rod 2a, the rotating sleeve 2b rotates together with the turning rod 2a; as the rotating sleeve 2b rotates, the transmission guide groove on the transmission splint 2c begins to guide the transmission pin 2e to slide; since the transmission pin 2e is fixed on the shaft sleeve ring 2d, the sliding of the transmission pin 2e will drive the shaft sleeve ring 2d to slide on the input shaft 21 and the output shaft 22; since the shaft sleeve ring 2d and the linkage ring 25 are fixedly connected, the sliding of the shaft sleeve ring 2d will drive the linkage ring 25 to slide on the input shaft 21 and the output shaft 22; in this way, the linkage ring 25 changes the effective transmission radius of the belt between the driving disc 23 and the driven disc 24 through the speed regulation component, thereby adjusting the throwing speed; after adjusting to the required throwing speed, the operator can use the locking component to lock the rotation position of the turning rod 2a, thereby fixing the speed ratio and ensuring the stability of the throwing speed.

[0073] A limiting ring 27 is fixed on the input shaft 21 and the output shaft 22. During the operation of the drive device, the linkage ring 25 will slide on the input shaft 21 and the output shaft 22 according to the instructions of the control component to adjust the effective transmission radius of the belt. The presence of the limiting ring can prevent the linkage ring from detaching from the shaft sleeve ring or damaging the speed regulation component due to excessive movement during the sliding process. It provides a clear sliding boundary for the linkage ring, ensuring that it moves within the allowable range and maintaining the structural stability of the entire drive device.

[0074] like Figure 5 As shown, the locking assembly includes:

[0075] The handle 31 is fixedly connected to the rotating rod 2a and is arranged outside the speed regulating box 1;

[0076] The locking pin 32 is slidably inserted into the handle 31;

[0077] A plurality of lock holes 33 are arranged circumferentially on the top of the speed regulating box 1 for guiding the insertion of the locking pin 32;

[0078] The working process and principle of the locking assembly are as follows: after adjusting to the required throwing speed, the operator needs to lock the position of the rotating rod 2a to prevent it from accidentally rotating; the operator slides the locking pin 32 out from the handle 31 and aligns it with a locking hole 33 at the top of the speed regulating box 1; after the locking pin 32 is inserted into the locking hole 33, since the shape and size of the locking hole 33 match the locking pin 32, the locking pin 32 will be firmly fixed in the locking hole 33; in this way, the rotating rod 2a is firmly locked in the current rotation position and cannot rotate anymore, ensuring the stability and accuracy of the throwing speed.

[0079] The locking assembly also includes:

[0080] The sleeve 34 is fixedly mounted on the handle 31 and covers the locking pin 32;

[0081] The spring pressing piece 35 is fixedly sleeved on the locking pin 32;

[0082] The elastic spring 36 is sleeved on the locking pin 32, the bottom end of the elastic spring 36 is fixedly connected to the spring pressing plate 35, and the top end of the elastic spring 36 is in contact with the top end of the sleeve 34;

[0083] When the operator locks the position of the rotating rod 2a, the elastic spring 36 pushes the spring pressure plate 35 to move downward, and then the spring pressure plate 35 drives the locking pin 32 to move downward until the locking pin 32 is inserted into the corresponding locking hole 33. The elastic spring 36 can provide a certain pressure to the locking pin 32 to prevent the locking pin 32 from being accidentally pulled out of the locking hole 33, thereby improving operational stability.

[0084] A pull tab 37 is provided at the top of the locking pin 32; the pull tab 37 can increase the operating area and provide a point of force for easy application, so that the operator can complete the locking and unlocking actions more easily; the pull tab 37 makes the operator feel more comfortable and labor-saving during operation.

[0085] The bottom end of the locking pin 32 is set to be a spherical surface; the spherical surface has a smooth contour, which can more easily adapt to the edge of the lock hole 33, thereby reducing friction and resistance during insertion and removal; it helps to improve the reliability of locking and the convenience of operation; because the spherical surface has the same curvature radius in all directions, it can better adapt to the slight deviations or irregular shapes that may exist in the lock hole 33; this helps to ensure that the locking pin 32 can be smoothly inserted and removed from the lock hole.

[0086] The installation, connection or setting method of the driving device for adjusting the wheel throwing speed of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects.

[0087] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
