[0027] like Figure 1-5 As shown, as an embodiment of the utility model, a transmission structure 100 for separating and rotating a mold 200 is disclosed, wherein the mold 200 includes a plurality of horizontally arranged mold strips 20, and each mold strip 20 is arranged along its width direction. The transmission structure 100 includes a driving device 1, a rotating device 2, and a separating device 3. The driving device 1 includes a driving seat 13, a driving shaft 11 rotatably connected to the driving seat 13, and a driving motor 12 for driving the driving shaft 11 to rotate. The driving seat 13 is used to install and position the driving shaft 11 on an external frame, and both ends of the driving shaft 11 extend out of the driving seat 13 respectively. The rotating device 2 is connected to one end of the driving shaft 11 through a first transmission mechanism 4, and can rotate with the rotation of the driving shaft 11. The rotating device 2 is used to grab the mold strip 20 and drive the mold strip 20 to flip to an upright state. The separation device 3 is connected to the other end of the driving shaft 11 through the second transmission mechanism 5, and can be raised and lowered with the rotation of the driving shaft 11. The separation device 3 is arranged below the rotating device 2, and is used to sequentially drive a mold bar 20 arranged at the end to rise and be installed on the rotating device 2. In the transmission structure 100 of this embodiment, since the rotating device 2 and the separation device 3 are respectively connected to the two ends of the driving shaft 11, and the rotating device 2 can rotate with the rotation of the driving shaft 11, and the separation device 3 can be raised and lowered with the rotation of the driving shaft 11, the rotating device 2 and the separation device 3 can be driven to operate at the same time by a driving motor 12, which greatly reduces the production and manufacturing costs of the manufacturer, and eliminates the process of installing, debugging and maintaining the coordination of the two motors in the prior art, which is convenient for installation and maintenance.

[0028] In some specific embodiments, the driving shaft 11 rotates one stroke to drive the separation device 3 to rise and fall one stroke, and drives the rotating device 2 to rotate one stroke, and the rotating device 2 is in a stationary state when the separation device 3 rises, and starts to rotate when the separation device 3 descends or after it descends, thereby reserving sufficient time for the mold strip 20 to be installed on the rotating device 2, so that the separation device 3 can push the mold strip 20 to rise until it is accurately installed on the rotating device 2.

[0029] like Figure 2As shown, in some specific embodiments, the first transmission mechanism 4 includes a transmission member 41 for converting rotational motion into intermittent rotational motion. The input end of the transmission member 41 is transmission-connected to the end of the drive shaft 11, and can rotate with the rotation of the drive shaft 11. The output end of the transmission member 41 is transmission-connected to the rotating device 2, and can drive the rotating device 2 to rotate a stroke when or after the separation device 3 is lowered. The setting of the transmission member 41 facilitates the control of the rotation direction, angle, and start and stop time of the rotating device 2, and further facilitates the control of the linkage operation of the rotating device 2 and the separation device 3. In this embodiment, the transmission member 41 adopts a cam divider commonly seen on the market, which is convenient for assembly. In other embodiments, the transmission member 41 can also adopt other structures such as gear assemblies that can convert rotational motion into intermittent rotational motion.

[0030] like Figure 3 As shown, in some specific embodiments, the driving device 1 is arranged below the separation device 3, the driving shaft 11 is arranged in the horizontal direction, and the first transmission mechanism 4 further includes a first transmission shaft 42 arranged in the vertical direction, a first bevel gear 44 fixed relative to the end of the driving shaft 11, and a second bevel gear 45 fixed relative to the lower end of the first transmission shaft 42. The second bevel gear 45 is meshedly connected with the first bevel gear 44, and is used to drive the first transmission shaft 42 to rotate with the rotation of the driving shaft 11. The upper end of the first transmission shaft 42 is transmission-connected with the input end of the transmission member 41, and can drive the input end of the transmission member 41 to rotate with the rotation of the first transmission shaft 42, thereby driving the input end of the transmission member 41 to rotate with the rotation of the driving shaft 11.

[0031] In some specific embodiments, the first transmission mechanism 4 further includes a second transmission shaft 43 arranged perpendicularly to the drive shaft 11 and the first transmission shaft 42, a third bevel gear 46 fixed relative to the upper end of the first transmission shaft 42, and a fourth bevel gear 47 fixed relative to the second transmission shaft 43. The fourth bevel gear 47 is meshedly connected with the third bevel gear 46, and is used to drive the second transmission shaft 43 to rotate with the rotation of the first transmission shaft 42. The end of the second transmission shaft 43 is relatively fixedly connected to the input end of the transmission member 41, and is used to drive the input end of the transmission member 41 to rotate with the rotation of the second transmission shaft 43.

[0032] like Figure 2As shown, in some specific embodiments, the rotating device 2 includes a rotating seat 23, a rotating shaft 21 arranged parallel to the driving shaft 11, and one or more rotating disks 22 arranged coaxially with the rotating shaft 21 and relatively fixed. One end of the rotating shaft 21 is relatively fixedly connected to the output end of the transmission member 41, and the other end is rotatably connected to the rotating seat 23. The rotating seat 23 is used to install and position the rotating shaft 21 on an external frame. The rotating shaft 21 can rotate with the rotation of the output end of the transmission member 41, and the rotating disk 22 can rotate with the rotation of the rotating shaft 21. The rotating disk 22 is provided with a plurality of positioning grooves 221 for grabbing the mold strips 20 along its circumferential direction. The positioning grooves 221 are arranged along the radial direction of the rotating disk 22. When one of the positioning grooves 221 rotates to the top of the separation device 3, the separation device 3 can drive a mold strip 20 arranged at the end to extend into the positioning groove 221 and be installed in the positioning groove 221. The positioning groove 221 grabs the mold strip 20 and can drive the mold strip 20 to flip from a horizontal state to a vertical state as the rotating disk 22 rotates. The angle of one rotation of the rotating device 2 is the same as the angle formed between two adjacent positioning grooves 221, so that the separation device 3 drives multiple mold strips 20 to sequentially extend into the positioning grooves 221 on the rotating disk 22, thereby realizing the continuous flipping of multiple mold strips 20.

[0033] In some specific embodiments, eight positioning grooves 221 are arranged along the circumferential direction of the rotating disk 22, and the positioning grooves 221 are arranged along the radial direction of the rotating disk 22. The eight positioning grooves 221 are evenly spaced, that is, the angle between two adjacent positioning grooves 221 is 45°. When the driving shaft 11 rotates one circle, the rotating shaft 21 rotates one stroke, that is, when the driving shaft 11 rotates one circle, the rotating shaft 21 and the rotating disk 22 rotate 45°, and the mold strip 20 in the positioning groove 221 can be turned over by 90° with the rotating disk 22 turning over two strokes, so that the water When flipping from a flat state to an upright state, when flipping multiple mold strips 20 continuously, the rotating disk 22 can drive the previous mold strip 20 to flip to 90° each time it rotates one stroke, and at the same time drive the next mold strip 20 to flip to 45°. Compared with only four positioning grooves 221, when flipping multiple mold strips 20 continuously, the rotating disk 22 only flips one mold strip 20 and needs to flip 90° each time it rotates one stroke. The flipping speed of this embodiment is faster and the continuous flipping efficiency is higher. Of course, in other embodiments, the positioning groove 221 can also be set to four. In this embodiment, the first bevel gear 44, the second bevel gear 45, the third bevel gear 46 and the fourth bevel gear 47 have the same number of teeth, that is, the transmission ratio of the first bevel gear 44, the second bevel gear 45, the third bevel gear 46 and the fourth bevel gear 47 is 1:1:1:1, so that the rotation speed of the input end of the transmission member 41 is the same as the rotation speed of the drive shaft 11, that is, when the drive shaft 11 rotates one circle, the input end of the transmission member 41 also rotates one circle. By setting the parameters of the transmission member 41 or selecting the transmission member 41 with the corresponding input-output ratio, the output end of the transmission member 41 can be rotated 45° in a preset direction when or after the separation device 3 descends.

[0034] like Figure 4 As shown, in some specific embodiments, the second transmission mechanism 5 includes a first rotating wheel 51 fixed relative to the other end of the driving shaft 11, a lower rocker arm 52 rotatably connected to the first rotating wheel 51 through a horizontally arranged first connecting shaft 54, and an upper rocker arm 53 rotatably connected to the separation device 3 through a horizontally arranged second connecting shaft 55. The first rotating wheel 51 can rotate with the rotation of the driving shaft 11. The first connecting shaft 54 ​​and the second connecting shaft 55 are arranged in parallel with the driving shaft 11, and the first connecting shaft 54 ​​is arranged in a staggered manner with the driving shaft 11, so that when the driving shaft 11 rotates, the first connecting shaft 54 ​​on the first rotating wheel 51 makes a circular motion around the driving shaft 11. The upper rocker arm 52 is connected to the lower rocker arm 53 in transmission connection. When the driving shaft 11 rotates one circle, the lower rocker arm 53 rotates one circle around the driving shaft 11 and drives the upper rocker arm 52 to rise and fall one stroke, and the upper rocker arm 52 drives the separation device 3 to rise and fall one stroke.

[0035] In some specific embodiments, the second transmission mechanism 5 further includes a third transmission shaft, the lower end of the third transmission shaft is relatively fixedly connected to the lower rocker arm 53, and the upper end of the third transmission shaft is relatively fixedly connected to the upper rocker arm 52, so that when the lower rocker arm 52 makes a circular motion around the drive shaft 11, the upper rocker arm 53 and the separation device 3 are driven to move up and down relative to the drive device 1 through the third transmission shaft. In this embodiment, the third transmission shaft is set as a straight rod structure with a simple structure. In other embodiments, the third transmission shaft can also be set as other shapes such as an arc rod, a bent rod, or the upper rocker arm 53 and the lower rocker arm 52 can also be connected to each other through other transmission structures such as a connecting rod assembly that can drive the upper rocker arm 53 to move with the lower rocker arm 52.

[0036] like Figure 4 As shown, in some specific embodiments, the separation device 3 includes a lifting seat 34, a connecting seat 32, a separating seat 33, and a plurality of lifting shafts 31 that can be lifted and connected to the lifting seat 34. In other embodiments, only one lifting shaft 31 can be provided. The two ends of the lifting shaft 31 extend out of the upper and lower sides of the lifting seat 34, respectively, and the lower ends of the plurality of lifting shafts 31 are respectively connected to the connecting seat 32, and the upper ends are respectively connected to the separating seat 33. The lifting seat 34 is used to install and position the lifting shaft 31 on an external frame. The upper rocker arm 53 is rotatably connected to the connecting seat 32 through a second connecting shaft 55, the mold bar 20 is arranged parallel to the rotating shaft 21, and the separating seat 33 includes a connecting rod portion 333 connected to the upper end of each lifting shaft 31, and a first separating portion 331 and a second separating portion 332 arranged on one side of the rotating disk 22, and the first separating portion 331 and the second separating portion 332 are arranged on the connecting rod portion 333. The first separation portion 331 is arranged in the horizontal direction and perpendicular to the mold strip 20, and is used to abut against the bottom of a mold strip 20 arranged at the end of the mold 200 before separation, and push the mold strip 20 to be installed in the positioning groove 221. The second separation portion 332 is arranged in the vertical direction and connected to the lower side of the first separation portion 331 close to the end of the mold 200, and is used to limit a mold strip 20 arranged at the end of the mold 200 after separation to be directly below the positioning groove 221, so that the first separation portion 331 can abut against its bottom and push the mold strip 20 to be installed in the positioning groove 221, thereby realizing continuous separation of each mold strip 20 in the mold 200.

[0037] like Figure 2 As shown, in some specific embodiments, the first transmission shaft 42 is mounted and positioned on the external frame through a first mounting seat 48 , and the transmission member 41 is mounted and positioned on the external frame through a second mounting seat 49 .

[0038] like Figure 5As shown, in some specific embodiments, the mold 200, the transmission member 41 and the rotating device 2 are correspondingly arranged in two groups, one end of the second transmission shaft 43 is relatively fixedly connected to the input end of one of the transmission members 41, and the other end is relatively fixedly connected to the input end of the other transmission member 41. The separation seat 33 can simultaneously push the mold strips 20 of the molds 200 on both sides to be installed in the positioning grooves 221 of the rotating disks 22 in the two rotating devices 2. The two sides of the connecting rod part 333 are respectively provided with a first separation part 331 and a second separation part 332 arranged corresponding to the two molds 200. The two rotating devices 2 are arranged in opposite directions, so that the separation device 3 and the two rotating devices 2 can be driven to work at the same time by a driving motor 12. The mold strips 20 arranged at the ends of the molds 200 on both sides can be turned 90° toward the middle area of ​​the two rotating devices 2 through the separation device 3 and the two rotating devices 2, respectively, so that the two mold strips 20 are turned at the same time, which improves the turning efficiency. Of course, in other embodiments, the rotating device 2 and the mold 200 can also be set in only one group.
