Description

Technical Field

[0001] The invention relates to the field of conveying devices, in particular to a paperboard conveying device for processing medicine packaging boxes. Background Art

[0002] Pharmaceutical packaging paperboard is a commonly used material in pharmaceutical packaging. It plays an important role in protecting drugs and ensuring the safety and effectiveness of drugs during circulation and use. Among them, white paperboard is made from waste paper pulp, and is divided into white-bottomed whiteboard and gray-bottomed whiteboard. The front and back of white-bottomed whiteboard are both white, while the front of gray-bottomed whiteboard is white and the back is gray. The front is smoother and the back is rougher. The paperboard materials fed into the packaging machine are in the shape of plates and stacked together. They can be handled or transported at one time, reducing the number of handling times and improving transportation efficiency. It can reduce the deformation of the paperboard caused by external forces (such as extrusion and collision), maintain the flatness and strength of the paperboard, facilitate quantity statistics and inventory management, and help improve logistics efficiency.

[0003] The pharmaceutical packaging cardboard conveying device is used to transport packaging cardboard in warehouses. At present, the entry and exit of cardboard goods in warehouses are mainly manual operations. For stacked packaging cardboard, a material tray is used to convey the cardboard. When the cardboard is heavy, the material tray is placed on the conveyor belt, and then the stacked cardboard is put in for transportation. However, in order to improve the transportation efficiency and save effort, the cardboard will hit the material tray during transportation, causing the material tray to shift on the conveyor belt surface, resulting in unstable transportation. Therefore, a cardboard feeding device for processing pharmaceutical packaging boxes is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a paperboard feeding device for processing medicine packaging boxes.

[0005] To achieve the above purpose, the technical scheme adopted by the present invention is: a cardboard paper feeding device for processing pharmaceutical packaging boxes, comprising a conveying platform, a plurality of conveyor belts are arranged on the upper surface of the conveying platform, two side edges of the upper surface of the conveying belt are respectively fixedly connected with side plates, a bending plate is connected with the upper side of the side plate through a distance adjustment mechanism, one side edge of the bending plate is fixedly connected with a limiting rod, a side of the two side plates close to each other is respectively connected with a square rod through a pulling mechanism, and a transverse rod is respectively fixedly connected with one end of the square rods on both sides close to each other, a rolling ring is rotatably connected with the side surface of the side plate, the rolling ring is sleeved on the outer side of the transverse rod, an inner ring is rotatably embedded with the inner side of the rolling ring through a friction mechanism, a guide rod is fixedly connected with the inner surface of the inner ring, a guide block is fixedly connected with the lower end of the guide rod, a spiral groove is opened on the outer surface of the transverse rod, the guide block slides into the inner side of the spiral groove, soft blocks are respectively fixedly connected with one end of the transverse rods on both sides close to each other, a material tray is arranged on the upper surface of the conveying platform, and the soft blocks on both sides clamp the two side surfaces of the material tray.

[0006] Preferably, the distance adjustment mechanism includes an adjusting screw threadedly penetrating the side surface of the bending plate, one end of the adjusting screw is rotatably connected to the side surface of the side plate, and a plurality of guide pillars are slidably penetrated through the side surface of the bending plate, and one end of the guide pillar is fixedly connected to the side surface of the side plate. By rotating the adjusting screw, the bending plate is transversely moved relative to the side plate. After the adjusting screws on both sides are adjusted respectively, the limit rods on both sides are moved closer or farther away from each other, which plays a role in limiting the material tray and preventing the material tray from excessively deviating during transportation. During the transverse movement of the bending plate, the guiding effect of the guide pillar can ensure that the bending plate moves smoothly. Obviously, one end of the adjusting screw can be fixedly connected to the polygonal head to facilitate the staff to perform the rotating action.

[0007] Preferably, the pulling mechanism comprises an extension plate fixedly connected to one end of the lower surface of the square rod, and a tension spring is fixedly connected between the side surface of the extension plate and the side plate. The tension of the tension spring makes the traverse rod have a tendency to move toward one side of the material tray, ensuring that the soft blocks on both sides can clamp the material tray. The soft block can be made of hard rubber material, which generates a large friction force with the material tray and will not scratch the surface of the material tray.

[0008] Preferably, two connecting frames are fixedly connected to the side surface of the side plate, and a snap-in edge is provided at the end of the connecting frame. A connecting ring is fixedly connected to the side surface of the rolling ring close to the side plate, and a bent edge is provided at the edge of the connecting ring, and the snap-in edge slides and snaps into the inner side of the connecting ring. When the rolling ring rotates, the bent edge rotates relative to the snap-in edge, and the problem of the rolling ring being separated from the connecting frame will not occur. Connecting frames are provided at the upper and lower positions for guidance to ensure stability when rotating with the rolling ring.

[0009] Preferably, the friction mechanism comprises a convex groove formed on the inner top surface of the rolling ring, a convex block is slidably inserted into the inner side of the convex groove, a plurality of compression springs are fixedly connected to the upper surface of the convex block, the upper end of the compression spring is fixedly connected to the inner top surface of the convex groove, and the lower surface of the convex block contacts the surface of the inner ring. The convex block is subjected to the elastic force of the compression spring, and the lower end surface of the convex block will be tightly pressed against the surface of the inner ring, and when the rolling ring just starts to rotate, it can rotate synchronously with the inner ring.

[0010] Preferably, the lower surface of the conveyor belt is fixedly connected to a support frame on both sides, and the lower end of the support frame is fixedly connected to the upper surface of the conveyor platform. The support frame raises the conveyor belt to prevent the lower surface of the conveyor belt from contacting the surface of the conveyor platform, thereby affecting the rotation of the conveyor belt.

[0011] Preferably, a base frame is fixedly mounted on the lower surface of the conveyor platform, and retaining frames are fixedly mounted on both sides of the lower surface of the base frame, and the front and rear ends of the retaining frames are slidably connected to tracks, and the lower surfaces of the two tracks are fixedly connected to a plurality of intermediate frames. When the base frame moves laterally, the retaining frames will move laterally along the tracks.

[0012] Preferably, the front and rear ends of the retaining frame are rotatably connected to contact wheels, the contact wheels are stuck in the inner side of the track, a motor is fixedly installed on the lower surface of the base frame, the output shaft of the motor is fixedly connected to a transmission gear, a rack is fixedly installed on the rear surface of the front track through a mounting frame, and the transmission gear is meshed with the rack. When the base frame moves horizontally, the contact wheels roll along the inner side of the track to ensure the stability of the horizontal movement of the base frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When cardboard is placed in the tray of the present invention, the clamping effect of the soft blocks on both sides can prevent the tray from being loosened due to impact, and effectively prevent the tray from tipping over when it is placed.

[0014] 2. In the present invention, when the conveyor belt drives the material tray to move backward, the conveyor belt will cause the rolling ring to rotate, and then the guide rod will rotate around the transverse rod, and the guide block will move along the inner side of the spiral groove, and then the transverse rod will move toward the side away from the material tray. The square rod moves horizontally to pull the tension spring, and the soft block no longer clamps the material tray. At this time, it is ensured that the conveyor belt can drive the material tray to move. When the guide rod continues to rotate until the guide block abuts against one end of the spiral groove close to the soft block, the inner ring is relatively still, and the rolling ring continues to rotate relative to the inner ring, and the problem of mechanism jamming will not occur. Therefore, with the start of transportation, the clamping and positioning of the material tray can be automatically relaxed to ensure rapid transportation.

[0015] 3. In the present invention, the operation of the motor causes the transmission gear to roll along the surface of the rack, thereby driving the conveyor table to move horizontally to achieve the transfer of cardboard. When it reaches one end of the track, the conveyor belt drives the material tray to move backward to complete the transfer of a certain amount of cardboard. After the conveyor table is reset, the staff applies external force to clamp the new batch of material trays between the soft blocks on both sides, and then the next cardboard can be put in and transferred.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-Figure 9The paper feeding device for processing a medicine packaging box shown in the figure comprises a conveying platform 1, and a plurality of conveyor belts 3 are arranged on the upper surface of the conveying platform 1. The conveyor belt 3 is a servo conveyor belt, and a conveying device that uses a servo motor and a related control system to accurately control the speed and position of the conveyor belt is used. It is a prior art and will not be described in detail. The two side edges of the upper surface of the conveyor belt 3 are respectively fixedly connected with side plates 5, and the upper part of the side plate 5 is connected with a bending plate 6 through a distance adjustment mechanism. One side edge of the bending plate 6 is fixedly connected with a limit rod 7, and the adjacent sides of the two side plates 5 are respectively connected with square rods 24 through a pulling mechanism, and the adjacent ends of the square rods 24 on both sides are divided into The side plate 5 is fixedly connected with a transverse rod 21, and the side surface of the side plate 5 is rotatably connected with a rolling ring 14, which is sleeved on the outer side of the transverse rod 21, and the inner side of the rolling ring 14 is rotatably embedded with an inner ring 15 through a friction mechanism, and the inner surface of the inner ring 15 is fixedly connected with a guide rod 19, and the lower end of the guide rod 19 is fixedly connected with a guide block 20, and the outer surface of the transverse rod 21 is provided with a spiral groove 22, and the guide block 20 slides into the inner side of the spiral groove 22, and the ends of the transverse rods 21 on both sides are fixedly connected with soft blocks 23 respectively, and a material tray 4 is provided on the upper surface of the conveying platform 1, and the soft blocks 23 on both sides clamp the two side surfaces of the material tray 4.

[0020] like Figure 4 As shown, the distance adjustment mechanism includes an adjusting screw 8 threadedly penetrating the side surface of the bending plate 6, one end of the adjusting screw 8 is rotatably connected to the side surface of the side plate 5, and a plurality of guide pillars 9 are slidably penetrating the side surface of the bending plate 6, and one end of the guide pillar 9 is fixedly connected to the side surface of the side plate 5. The user rotates the adjusting screw 8 to make the bending plate 6 move laterally relative to the side plate 5. After the adjusting screws 8 on both sides are adjusted respectively, the limit rods 7 on both sides approach or move away from each other, which plays a role in limiting the material tray 4 and preventing the material tray 4 from excessively deviating during transportation. During the lateral movement of the bending plate 6, due to the guiding effect of the guide pillar 9, the bending plate 9 can be ensured to move smoothly. Obviously, one end of the adjusting screw 8 can be fixedly connected to the polygonal head to facilitate the staff to perform the rotation action.

[0021] like Figure 5 , Figure 6 , Figure 7 As shown, the pulling mechanism includes an extension plate 25 fixedly connected to one end of the lower surface of the square rod 24, and a tension spring 26 is fixedly connected between the side surface of the extension plate 25 and the side plate 5. The tension of the tension spring 26 makes the traverse rod 21 have a tendency to move toward the side of the material tray 4, ensuring that the soft blocks 23 on both sides can clamp the material tray 4. The soft blocks 23 can be made of hard rubber material, which generates a large friction force with the material tray 4 and will not scratch the surface of the material tray 4.

[0022] Two connecting frames 10 are fixedly connected to the side surface of the side plate 5, and a snap-in edge 13 is provided at the end of the connecting frame 10. A connecting ring 11 is fixedly connected to the side surface of the rolling ring 14 close to the side plate 5, and a bent edge 12 is provided at the edge of the connecting ring 11, and the snap-in edge 13 slides and snaps into the inner side of the connecting ring 11. When the rolling ring 14 rotates, the bent edge 12 will rotate relative to the snap-in edge 13, and the problem of the rolling ring 14 being separated from the connecting frame 10 will not occur. Connecting frames 10 are respectively provided at the upper and lower positions for guidance to ensure stability when rotating with the rolling ring 14.

[0023] The friction mechanism includes a convex groove 16 formed on the inner top surface of the rolling ring 14, a convex block 18 is slidably inserted into the inner side of the convex groove 16, a plurality of compression springs 17 are fixedly connected to the upper surface of the convex groove 16, the upper end of the compression spring 17 is fixedly connected to the inner top surface of the convex groove 16, and the lower surface of the convex block 18 contacts the surface of the inner ring 15. The convex block 18 is subjected to the elastic force of the compression spring 17, and the lower end surface of the convex block 18 will be tightly pressed against the surface of the inner ring 15, and when the rolling ring 14 just starts to rotate, it can rotate synchronously with the inner ring 15.

[0024] like Figure 3 As shown, the two sides of the lower surface of the conveyor belt 3 are fixedly connected with a support frame 2, and the lower end of the support frame 2 is fixedly connected to the upper surface of the conveyor platform 1. The support frame 2 raises the conveyor belt 3 to prevent the lower surface of the conveyor belt 3 from contacting the surface of the conveyor platform 1, thereby affecting the rotation of the conveyor belt 3.

[0025] like Figure 1 , Figure 2 As shown, a bottom frame 27 is fixedly mounted on the lower surface of the conveyor 1, and retaining frames 28 are fixedly mounted on both sides of the lower surface of the bottom frame 27, and the front and rear ends of the retaining frames 28 are slidably connected to rails 34, and the lower surfaces of the two rails 34 are fixedly connected to a plurality of intermediate frames 35. When the bottom frame 27 moves laterally, the retaining frames 28 will move laterally along the rails 34.

[0026] The front and rear ends of the retaining frame 28 are rotatably connected with contact wheels 29 respectively, and the contact wheels 29 are stuck in the inner side of the track 34. A motor 30 is fixedly installed on the lower surface of the base frame 27, and the output shaft of the motor 30 is fixedly connected with a transmission gear 31. A rack 32 is fixedly installed on the rear surface of the front track 34 through a mounting frame 33, and the transmission gear 31 is meshed with the rack 32. When the motor 30 rotates, the transmission gear 31 rolls along the surface of the rack 32, thereby driving the conveyor 1 to move horizontally to realize the transfer of cardboard. When it reaches one end of the track 34, the conveyor belt 3 drives the material tray 4 to move backward to complete the transfer of a certain amount of cardboard. When the base frame 27 moves horizontally, the contact wheel 29 rolls along the inner side of the track 34 to ensure the stability of the horizontal movement of the base frame 27.

[0027] During use, when the staff puts the cardboard into the tray 4, the clamping effect of the soft blocks 23 on both sides can prevent the tray 4 from being loosened due to impact, and effectively prevent the tray 4 from tipping over when it is placed. The soft blocks 23 are made of hard rubber material, which can effectively prevent the tray 4 from being scratched.

[0028] When the conveyor belt 3 drives the material tray 4 to move backward, the backward movement of the conveyor belt 3 will cause the rolling ring 14 to rotate, and then the guide rod 19 will rotate around the transverse rod 21, and the guide block 20 will move along the inner side of the spiral groove 22, so that the transverse rod 21 will move toward the side away from the material tray 4, and the square rod 24 will move laterally to pull the tension spring 26, and the soft block 23 will no longer clamp the material tray 4. At this time, it is ensured that the conveyor belt 3 can drive the material tray 4 to move. When the guide rod 19 continues to rotate, until the guide block 20 rests on one end of the spiral groove 22 close to the soft block 23, the inner ring 15 is relatively stationary, and the rolling ring 14 continues to rotate relative to the inner ring 15, and the problem of mechanism jamming will not occur. Therefore, with the start of transportation, the clamping and positioning of the material tray 4 can be automatically relaxed to ensure rapid transportation.

[0029] Through the operation of the motor 30, the transmission gear 31 rolls along the surface of the rack 32, thereby driving the conveyor platform 1 to move horizontally to achieve the transfer of cardboard. When it reaches one end of the track 34, the conveyor belt 3 drives the material tray 4 to move backward to complete the transfer of a certain amount of cardboard. After the conveyor platform 1 is reset, the staff applies external force to clamp the new batch of material trays 4 between the soft blocks 23 on both sides, and then the next cardboard can be put in and transferred.
