Description

Technical Field

[0001] This utility model relates to the field of paint drum manufacturing and processing, and in particular to a feeding mechanism for installing the bottom cover of a paint drum. Background Technology

[0002] Paint drums mainly consist of a drum body, an upper lid, and a lower bottom lid. When installing the bottom lid, multiple lids are stacked together and placed in a conveying mechanism at the top of the processing equipment. This mechanism has a discharge port and a slide rail connected to the discharge port. Supports are located below both the discharge port and the slide rail. The bottom lid is placed on the support rail below the discharge port. The conveying mechanism pushes the bottommost bottom lid along the slide rail into the processing mechanism, where it is installed on the drum body. After the conveying mechanism returns, the second-to-last bottom lid falls onto the support rail, and the conveying continues. However, when conveying the bottommost bottom lid, the other bottom lids are pressed on top of it, resulting in significant resistance and affecting the conveying process. Utility Model Content

[0003] The purpose of this invention is to provide a feeding mechanism for installing the bottom cover of an iron drum, which has the advantages of reducing the pressure on the drum cover and facilitating its conveying.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A feeding mechanism for installing a bottom cover of an iron drum includes a mounting frame with a conveying mechanism. The mounting frame has a discharge port at its top, and four vertical limiting rods are fixedly connected around the discharge port. The inner wall of the discharge port has a step. A slide rail is located at the top of the mounting frame and connected to the discharge port. Grooves are formed on the inner walls of both sides of the slide rail. The mechanism is characterized by two fixed support seats at the top of the mounting frame, with both ends of the support seats extending across the discharge port and fixedly connected to the mounting frame. The discharge port is located below the support seats. Each support seat has a driving mechanism at its upper part, and an end face cam is rotatably connected below each support seat. The end face cam is connected to the driving mechanism. The driving mechanism includes a cylinder, a gear, and a rack. The gear is rotatably connected to the support seat, located above the end face cam, and fixedly connected to the end face cam via a rotating shaft. The cylinder is fixedly connected to the side of the support seat, and the rack is fixedly connected to the cylinder's output shaft. The rack passes through the support seat and is slidably connected to it, meshing with the gear.

[0006] Using the above technical solution, the stacked bottom covers are placed on the uppermost contour of the end face cams of the two support seats to support them. A cylinder extends and pushes a connecting plate, causing two racks to move. The racks, through meshing gears, drive the end face cams on the two support seats to rotate 360 ​​degrees. When the end face cams rotate to 180 degrees, their top contours separate from the bottom covers, and the bottom contour of the end face cam rotates to below the bottom covers. The bottom cover loses the support of the end face cams and falls off, landing on the step of the discharge port. The second-to-last bottom cover descends to the bottommost end of the end face cam, contacting the hubs on both sides of its bottommost end. The end face cams continue to rotate, and the hubs of the end face cams exert force on the second-to-last bottom cover. The force generated by the action of the end cam causes the bottom cover to rise, which in turn causes the other bottom covers above to rise. The end cam moves the second-to-last bottom cover to its top surface contour, separating it from the bottom cover. The conveying mechanism pushes the bottom cover into the processing mechanism and installs it at the bottom of the barrel. The conveying mechanism returns, and at the same time, the cylinder output shaft retracts, causing the end cam to rotate again. The second-to-last bottom cover falls down onto the step of the discharge port. The bottom cover above it separates from it under the action of the end cam. Then the conveying mechanism again drives the end cover into the processing mechanism. During the conveying process, the bottom cover is separated from the bottom cover above it to avoid putting pressure on the bottom cover, making it easier to drive the bottom cover into the processing mechanism.

[0007] Preferably, the support base includes an upper base plate and a lower base plate. The lower base plate is fixedly connected to the top of the mounting frame. The upper base plate is fixedly connected to the lower base plate via a support shaft. The gear is located between the upper and lower base plates, with both ends rotatably connected to the upper and lower base plates respectively. The end face cam is located below the lower base plate and is fixedly connected to the gear. The rack passes between the upper and lower base plates and meshes with the gear.

[0008] By adopting the above technical solution, the rack and pinion can be driven to move and the gears to rotate more stably.

[0009] Preferably, the conveying mechanism includes a synchronous belt with a motor, which is located below the top side of the mounting frame and connected to the side of the mounting frame. A mounting plate is slidably connected to the bottom of the top of the mounting frame, and the mounting plate is fixedly connected to the conveyor belt of the synchronous belt. A push block is fixedly connected to the upper part of the mounting plate. A slot is opened at the top of the mounting frame, which is connected to the discharge port. The push block is located in the slot, and the height of the top surface of the push block is greater than the height of the lower surface of the discharge port step.

[0010] Using the above technical solution, the synchronous belt rotates, pulling the mounting plate to move. The mounting plate drives the pusher block to move, and the pusher block pushes the bottom cover on the feed port step into the slide. The edge of the bottom cover is embedded in the groove on the inner wall of the slide, and the bottom cover is pushed into the processing mechanism along the slide.

[0011] Preferably, the rack is cylindrical.

[0012] The above technical solution increases the stability of the motion.

[0013] Preferably, the pusher is made of nylon.

[0014] The above technical solution improves the durability and strength of the push block, while also making it easier to push the bottom cover. Attached Figure Description

[0024] See Figures 1 to 6A feeding mechanism for installing a bottom cover of an iron drum includes a mounting frame 1 with a conveying mechanism. The top of the mounting frame 1 has a discharge port 2, and the inner wall of the discharge port 2 has steps 4. Four vertical limiting rods 3 are fixedly connected to the mounting frame 1 around the discharge port 2. A slide rail 5 is located at the top of the mounting frame 1 and connects to the discharge port 2. The inner walls of both sides of the slide rail 5 have slots. A synchronous belt 11 is connected to the side of the mounting frame 1. The synchronous belt 11 includes two pulleys and a belt. The mounting frame 1 is rotatably connected to the side of the mounting frame 1. The belt is fitted onto the pulley, one of which is connected to a motor. The synchronous belt 11 is located on the lower side of the top of the mounting frame 1. The mounting plate 12 is slidably connected to the lower top of the mounting frame 1. The mounting plate 12 is fixedly connected to the conveyor belt of the synchronous belt 11. The upper part of the mounting plate 12 is fixedly connected to the push block 13. The top of the mounting frame 1 has a slot, which is connected to the discharge port 2. The push block 13 is located in the slot, and the height of the top surface of the push block 13 is greater than the height of the lower surface of the step 4 of the discharge port 2.

[0025] See 2 to Figure 7 The mounting frame 1 has two fixed support seats 6 at its top. The two ends of the support seats 6 span the discharge port 2 and are fixedly connected to the mounting frame 1. The discharge port 2 is located below the support seats 6. The support seats 6 include an upper base plate and a lower base plate. The lower base plate is fixedly connected to the top of the mounting frame 1, and the upper base plate is fixedly connected to the lower base plate through a support shaft. The support seats 6 also include gears 7, which are located between the upper and lower base plates and are rotatably connected to the upper and lower base plates at both ends. Each support seat 6 is connected to two gears 7. The gears 7 are fixedly connected to the rotational connection shaft of the lower base plate with an end face cam 8. The end face cam 8 is located below the lower base plate. The two support seats 6 are fixedly connected to horizontal cylinders 9 on their sides. The output shafts of the two cylinders 9 are fixedly connected to cylindrical racks 10. The two racks 10 pass through the upper and lower base plates of the two support seats 6 respectively, and each rack 10 meshes with the two gears 7 on its support seat 6.

[0026] Working principle: The stacked bottom covers are placed on the uppermost contour of the end face cams 8 of the two support seats 6 to support the bottom covers. The cylinder 9 extends and pushes the connecting plate to drive the two racks 10 to move. The racks 10 drive the end face cams 8 on the two support seats 6 to rotate 360 ​​degrees through the gears 7 meshing with them. When the end face cams 8 rotate to 180 degrees, the top contour of its top separates from the bottom cover, and the bottom contour of the end face cam 8 rotates to be below the bottom cover. The bottom cover loses the support of the end face cams 8 and falls off the end face cams 8, landing on the step 4 of the discharge port 2. The second to last bottom cover descends to the bottom of the end face cam 8 and contacts the hubs on both sides of its bottom end. The end face cam 8 continues to rotate, and the hubs of the end face cam 8 exert a force on the second to last bottom cover, causing it to rise, thereby causing the other bottom covers above to rise. The end face cam 8 drives the second to last bottom cover to rise. The bottom cover of the first layer moves to the outline of its top surface and separates from the bottom cover of the lowest layer. The synchronous belt 11 rotates, pulling the mounting plate 12 to move. The mounting plate 12 drives the push block 13 to move. The push block 13 pushes the bottom cover on the step 4 of the discharge port 2 into the slide 5. The edge of the bottom cover is embedded in the groove on the inner wall of the slide 5. The bottom cover is pushed into the processing mechanism along the slide 5 and installed at the bottom of the barrel. The synchronous belt 11 reverses and pulls the push block 13 back. At the same time, the output shaft of the cylinder 9 retracts and drives the end face cam 8 to rotate again. The bottom cover of the second to last layer descends and falls on the step 4 of the discharge port 2. The bottom cover of the upper layer separates from it under the action of the end face cam 8. Then the conveying mechanism drives the end cover into the processing mechanism again. During the conveying, the bottom cover of the lowest layer is separated from the bottom cover above it to avoid pressure on the bottom cover of the lowest layer, thus making it easier to drive the bottom cover into the processing mechanism.
