The output end of the second motor 24 is fixedly connected to one end of the first transmission shaft 25, the outer surface of the first transmission shaft 25 is fixedly connected to a cam 53, and a discharge chute 54 is provided on the side of the cooling box 18 close to the collecting box 19. The interior of the cooling box 18 is rotatably connected to a rotating screen plate 41, and the cam 53 is arranged at the bottom of the rotating screen plate 41. The cam 53 is driven to rotate by the first transmission shaft 25, which can The rotating screen plate 41 can be rotated up and down. The top of the rotating screen plate 41 is fixedly connected to a partition plate 42, and the top of the rotating screen plate 41 is divided into two parts by the partition plate 42. A rotating groove 43 is provided inside the rotating screen plate 41. There are multiple rotating grooves 43. The inside of the rotating groove 43 is rotatably connected to a power shaft 47 extending to the outside of the rotating screen plate 41. The outer surface of the power shaft 47 is fixedly connected to four tipping racks 44. The four tipping racks 44 are equidistantly arranged on the power shaft 47 in a circular array.

[0035] A transmission groove 50 is provided inside the gear 46, and the power shaft 47 is located inside the transmission groove 50. A slide groove 51 is provided inside the power shaft 47. A trapezoidal groove 48 communicating with the interior of the transmission groove 50 is provided inside the gear 46. The cross-section of the trapezoidal groove 48 is a right-angled trapezoid.

[0036] When the workpiece falls on the top of the rotating screen plate 41, the staff starts the second motor 24, and the second motor 24 drives the first transmission shaft 25 to rotate, and the first transmission shaft 25 drives the cam 53 to rotate, so that the rotating screen plate 41 can be rotated up and down. At the same time, the rotating screen plate 41 is rotated upward, so that the gear 46 rotates with the cooperation of the arc groove 45. At the same time, the cross-section of the trapezoidal groove 48 is trapezoidal, so that the right angle of the trapezoidal groove 48 faces the positioning rod 49 to block, so that the gear 46 can drive the power shaft 47 to rotate, and after the workpiece slides to the top of the baffle 55 under the action of gravity, the power shaft 47 drives the workpiece to flip and move downward through the turning rack 44, so that the workpiece can be more evenly exposed to the air, and the cooling speed of the workpiece is accelerated, so that the workpiece can be cooled more smoothly. The cooled workpiece is discharged from the inside of the discharge chute 54 to the inside of the collection box 19 for classification and collection.

[0037] At the same time, the cross-section of the trapezoidal groove 48 is trapezoidal. During the downward movement of the gear 46, the inclined surface of the trapezoidal groove 48 pushes the positioning rod 49 to slide out of the interior of the trapezoidal groove 48, and the gear 46 cannot drive the power shaft 47 to rotate, thereby avoiding the reverse rotation of the tipping rack 44 to squeeze the workpiece and causing the device to get stuck, and at the same time allowing the device to run more smoothly.

[0038] The transmission material distribution assembly includes a material transfer plate 56, the surface of the material transfer plate 56 is fixedly connected to the interior of the classification box 20, and the material transfer plate 56 is arranged in an inclined shape inside the classification box 20, so that the workpiece can move more smoothly. The interior of the classification box 20 is rotatably connected to two symmetrical second transmission shafts 30, and a second screening roller 35 is fixedly connected between the two second transmission shafts 30. The interior of the classification box 20 is rotatably connected to two third transmission shafts 31 and two transmission rods 57, and a first screening roller 34 is fixedly connected between the two transmission rods 57.

A transmission roller 36 is fixedly connected therebetween, and the second screening roller 35 is arranged between the first screening roller 34 and the transmission roller 36. Screening grooves are provided on the first screening roller 34 and the second screening roller 35, and the screening grooves on the first screening roller 34 are larger than the screening grooves on the second screening roller 35, and the length, width and height of the screening grooves are different. A diverter plate 37 is fixedly connected to the top of the transfer plate 56. There are multiple diverter plates 37. Through two adjacent diverter plates 37, the two diverter plates 37 can limit and guide the workpiece, and enable the workpiece to be screened and classified more smoothly.

[0039] Specifically, a partition 39 is fixedly connected to the bottom of the material transfer plate 56, and a first guide plate 38 and a second guide plate 40 are fixedly connected to the interior of the classification box 20. The partition 39 is arranged between the first guide plate 38 and the second guide plate 40. The first guide plate 38 and the partition 39 are arranged at a relative inclination, so that the workpieces falling on the second guide plate 40 and the first guide plate 38 can move to both sides and realize the classification and diversion of the workpieces.

[0040] The surfaces of the first transmission shaft 25 and the rear second transmission shaft 30 are fixedly connected with active transmission wheels 27, and the two active transmission wheels 27 are connected to the first belt 26 for transmission. The rear transmission rod 57 and the rear third transmission shaft 31 are fixedly connected with the first driven transmission wheel 28, and the two first driven transmission wheels 28 are connected to the second belt 29 for transmission.

[0041] The staff starts the second motor 24, and the second motor 24 drives the second transmission shaft 30 to rotate through the active transmission wheel 27 and the first belt 26. The second transmission shaft 30 drives the third transmission shaft 31 to rotate through the third transmission wheel 32 and the third belt 33. The third transmission shaft 31 drives the transmission rod 57 to rotate through the second belt 29 and the first driven transmission wheel 28, so that the two workpieces falling on the material transfer plate 56 are adjusted to be parallel to the axial direction of the transmission roller 36 under the obstruction of the transmission roller 36 and the tilt setting of the material transfer plate 56. When the workpiece is parallel to the axial direction of the transmission roller 36, the friction between the workpiece and the transmission roller 36 is maximized, so that The transmission roller 36 drives the workpiece to move to the second screening roller 35. Due to the restriction of the diverter plate 37, when the workpiece coincides with the screening groove on the second screening roller 35, the workpiece falls on the first guide plate 38 through the screening groove on the second screening roller 35. The workpiece larger than the screening groove on the second screening roller 35 moves to the first screening roller 34 driven by the second screening roller 35, falls on the second guide plate 40 through the screening groove of the first screening roller 34, and through the inclined setting of the first guide plate 38 and the second guide plate 40, the workpieces are classified and fall on both sides of the rotating screen plate 41, and the classified collection of the workpieces is realized, so that the staff can use the device more conveniently.

[0042] Working principle: An injection molding mechanism for the production of stapler cartridges. When in use, the staff starts the extruder 2, and after the extruder 2 performs injection molding on the inside of the left mold 14 and the right mold 15, the staff starts the first motor 4, and the first motor 4 drives the rotating shaft 5 to rotate. The rotating rod 7 is arranged on the side away from the rotating plate 6, so that the rotating shaft 5 can drive the rotating rod 7 to rotate eccentrically through the rotating plate 6, and the transmission plate 8 and the fan-shaped plate 11 are driven to rotate back and forth by the rotating rod 7, and the knocking ball 13 can knock on the left mold 14 to a certain extent. At the same time, the knocking of the left mold 14 by the knocking ball 13 causes the solution inside the left mold 14 to vibrate to a certain extent, and the material inside the molding chamber of the left mold 14 is squeezed more tightly, which reduces the occurrence of bubbles in the material inside the molding chamber of the left mold 14 to a certain extent, and ensures the molding quality of the workpiece to a certain extent.

[0043] The staff starts the cylinder 16 to move the left mold 14 away from the right mold 15 and realize the mold opening of the device. At the same time, the molded mold can be discharged from the interior of the left mold 14 and the right mold 15 through the ejector in the prior art mold. The two discharged workpieces fall on the transfer plate 56 through the guide of the receiving plate 22. The staff starts the second motor 24, and the second motor 24 drives the second transmission shaft 30 to rotate through the active transmission wheel 27 and the first belt 26. The second transmission shaft 30 drives the third transmission shaft 31 to rotate through the third transmission wheel 32 and the third belt 33. The third transmission shaft 31 drives the transmission rod 57 to rotate through the second belt 29 and the first driven transmission wheel 28, so that the two workpieces falling on the transfer plate 56 are blocked by the transmission roller 36. The material transfer plate 56 is adjusted to be parallel to the axial direction of the transmission roller 36 under the inclined setting. When the workpiece is parallel to the axial direction of the transmission roller 36, the friction between the workpiece and the transmission roller 36 is maximized, so that the transmission roller 36 drives the workpiece to move to the second screening roller 35. Through the restriction of the diverter plate 37, when the workpiece coincides with the screening groove on the second screening roller 35, the workpiece falls on the first guide plate 38 through the screening groove on the second screening roller 35. The workpiece larger than the screening groove on the second screening roller 35 is driven by the second screening roller 35 to move to the first screening roller 34, and falls on the second guide plate 40 through the screening groove of the first screening roller 34. The inclined setting of the first guide plate 38 and the second guide plate 40 allows the workpieces to be classified and fall on both sides of the rotating screen plate 41, thereby realizing the classified collection of the workpieces.

[0044] When the workpiece falls on the top of the rotating screen plate 41, the second motor 24 drives the first transmission shaft 25 to rotate, and the cam 53 is driven to rotate by the first transmission shaft 25, so that the rotating screen plate 41 can be rotated up and down. At the same time, the rotating screen plate 41 is rotated upward, so that the gear 46 rotates in cooperation with the arc groove 45. At the same time, the cross section of the trapezoidal groove 48 is trapezoidal, so that the right angle of the trapezoidal groove 48 faces the positioning rod 49 to block, so that the gear 46 can drive the power shaft 47 to rotate, and after the workpiece slides to the top of the stop rod 55 under the action of gravity, the power shaft 47 drives the workpiece to flip and move downward through the turning rack 44, so that the workpiece can be more evenly exposed to the air, and the cooling speed of the workpiece is accelerated, so that the workpiece can be cooled more smoothly. The cooled workpiece is discharged from the inside of the discharge chute 54 to the inside of the collection box 19 for classification and collection;

[0045] At the same time, the cross-section of the trapezoidal groove 48 is trapezoidal. During the downward movement of the gear 46, the inclined surface of the trapezoidal groove 48 pushes the positioning rod 49 to slide out of the interior of the trapezoidal groove 48, and the gear 46 cannot drive the power shaft 47 to rotate, thereby avoiding the reverse rotation of the tipping rack 44 to squeeze the workpiece and causing the device to get stuck, and at the same time allowing the device to run more smoothly.

[0046] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
