Description

Technical Field

[0001] This utility model relates to the field of paint bucket processing, specifically to a bucket wall pressing mechanism for paint bucket processing. Background Technology

[0002] Paint buckets are containers used for storing and transporting paint. In existing technology, when labels need to be affixed to the outer wall of the paint bucket, a bucket wall clamping device is required. The bucket wall clamping device mainly includes a rotating roller, a lifting device, a fixed plate, a pressure plate, and a drive motor. The drive motor is installed at the rear end of the rotating roller. During operation, one open end of the paint bucket needs to be fitted onto the rotating roller. Then, the lifting device can drive the fixed plate and the pressure plate to descend and clamp onto the upper outer wall of the paint bucket. Next, the label can be affixed to the outer wall from one side of the paint bucket. Finally, the drive motor can drive the rotating roller and the paint bucket outside it to rotate through the connecting shaft, while the pressure plate above the paint bucket remains stationary, pressing the paint bucket and the label on its surface to ensure that the label is adhered more tightly and flatly during the rotation of the paint bucket.

[0003] However, paint buckets come in various diameters. When the inner diameter of a paint bucket is larger than that of the roller, the roller cannot make full contact with the inner wall of the paint bucket. The paint bucket will fall, causing the upper part of its inner wall to contact the top of the roller, but the bottom part will not. This results in the paint bucket not being able to rotate synchronously when the roller is driven to rotate, because the top of the paint bucket is pressed down by the pressure plate, which affects the overall processing effect.

[0004] Therefore, it is necessary to invent a barrel wall clamping mechanism for processing paint buckets. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a barrel wall pressing mechanism for processing paint barrels, comprising a rotating roller, a fixed plate, a pressure plate, and a drive motor. A fixed plate is disposed above the rotating roller, and a pressure plate is connected to the lower end of the fixed plate. A drive motor is connected to the rear end of the rotating roller. A ring-shaped array of positioning components is disposed outside the rotating roller. A driving gear and a driven gear are installed in the inner cavity of the rotating roller. The driven gear is located on one side of the driving gear, and a limit component is disposed on the side of the driven gear away from the driving gear.

[0007] Based on the above features: the driven gear meshes with the driving gear, and the limiting component can limit the driven gear to prevent the driven gear and the driving gear from rotating on their own.

[0008] Preferably, a connecting shaft is fixedly installed at the center of the rear end of the roller, a movable groove is formed on one side surface of the rear end of the roller, the movable groove is aligned with the limiting component, and an annular array of through grooves is formed on the surface of the roller.

[0009] Based on the above features: the rotating roller is connected to the output end of the drive motor via a connecting shaft, which facilitates the drive motor to drive the rotating roller to rotate.

[0010] Preferably, the positioning component includes a positioning plate and a connecting rod fixedly connected to one side of the positioning plate, and a protrusion is provided on the side of the connecting rod away from the positioning plate.

[0011] Based on the above features: the connecting rod moves through the through slot, which facilitates the extension and retraction adjustment of the positioning plate driven by the connecting rod.

[0012] Preferably, the surface of the drive gear is provided with an annular array of arc-shaped holes, and bearings are provided at both ends of the center of the drive gear.

[0013] Based on the above features: the bearing is fixed at the inner wall of the center of both ends of the inner cavity of the roller, so that the driving gear is located at the center of the inner cavity of the roller.

[0014] Preferably, a damping shaft is mounted at the center of the driven gear, and a knob is provided at the end of the damping shaft away from the driven gear, the knob being located outside the rear end of the roller.

[0015] Based on the above characteristics: when the operator rotates the knob at the outer end, the knob will drive the driven gear to rotate through the damping shaft, and at the same time the driven gear will drive the driving gear to rotate.

[0016] Preferably, the limiting component includes a sleeve and an insertion hole on one side of the sleeve. A limiting rod is movably connected inside the sleeve. A baffle is installed at one end of the limiting rod, and a buffer spring is installed at the other end of the baffle.

[0017] Based on the above characteristics: when the limit rod moves away from the driven gear, the limit rod will deform by squeezing the buffer spring through the baffle. When the limit rod is released, the buffer spring will rebound the baffle and the limit rod. At this time, the limit rod will extend outward through the insertion hole and insert into the tooth groove on the surface of the driven gear, thereby improving the protection effect.

[0018] Preferably, the baffle and the buffer spring are located in the inner cavity of the sleeve, and a pull plate is fixedly connected to one side of the baffle.

[0019] Based on the above features: the pull plate can extend outward through the movable slot, making it convenient for staff to pull the baffle to drive the limit rod to extend and retract.

[0020] The beneficial effects of this utility model are:

[0021] 1. By setting up the positioning components, main gear, and driven gear, the size of the entire device can be adjusted according to the inner diameter of different paint buckets. When the forward knob drives the driven gear to rotate, the driven gear will drive the drive gear to rotate. The arc-shaped hole on the surface of the drive gear will push the protrusion to move away from the center of the drive gear. The protrusion will also drive the connecting rod to extend outward through the through groove, so that the positioning plate moves away from the roller. At this time, the overall diameter will increase. When the reverse knob is turned, the driven gear will drive the drive gear to reverse, so that the arc-shaped hole pulls the protrusion back. The protrusion will also drive the connecting rod to retract inward through the through groove, so that the positioning plate moves back and fits against the surface of the roller. At this time, the overall diameter will decrease, improving the overall adjustability.

[0022] 2. The limit component can limit the driven gear to prevent the driven gear and the driving gear from rotating on their own. When the limit rod is moved away from the driven gear by the pull plate, the limit rod will deform the buffer spring by squeezing it through the baffle. When the pull plate is released, the buffer spring will rebound the baffle and the limit rod. At this time, the limit rod will extend out through the insertion hole and insert into the tooth groove on the surface of the driven gear, thus improving the protection effect.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] See attached document Figure 1-4 This utility model provides a barrel wall pressing mechanism for processing paint buckets, including a rotating roller 1, a fixed plate 2, a pressure plate 3, and a drive motor 4. The fixed plate 2 is positioned above the rotating roller 1 (the rear end of the fixed plate 2 is connected to a lifting device, such as a cylinder or lifting screw, which is not specifically limited in this application). The pressure plate 3 is connected to the lower end of the fixed plate 2 and is located between the fixed plate 2 and the rotating roller 1. The drive motor 4 is connected to the rear end of the rotating roller 1, and a connecting shaft 11 is fixedly installed at the center of the rear end of the rotating roller 1. The rotating roller 1 is connected to the output end of the drive motor 4 through the connecting shaft 11. In the prior art, one open end of the paint bucket needs to be fitted onto the rotating roller 1, and then the lifting device can drive the fixed plate 2 and the pressure plate 3 to descend and press against the upper outer wall of the paint bucket. Then, the label can be... The paint can is attached to its outer wall from one side. Finally, the drive motor 4 can drive the rotating roller 1 and the paint can outside it to rotate through the connecting shaft 11, while the pressure plate 3 above the paint can remains stationary, pressing the paint can and the label on its surface tightly to ensure that the label is attached more tightly and flatly during the rotation of the paint can. The rotating roller 1 is provided with a ring array of positioning components 5. The rotating roller 1 is equipped with a driving gear 6 and a driven gear 7 in its inner cavity. The driven gear 7 is located on one side of the driving gear 6 and is meshed with the driving gear 6. A limit component 8 is provided on the side of the driven gear 7 away from the driving gear 6. The limit component 8 can limit the driven gear 7 and prevent the driven gear 7 and the driving gear 6 from rotating on their own.

[0031] The surface of the rotating roller 1 is provided with annular array-shaped through grooves 13. The positioning component 5 includes a positioning plate 51 and a connecting rod 52 fixedly connected to one side of the positioning plate 51. The connecting rod 52 passes through the through grooves 13. The positioning plate 51 is located outside the rotating roller 1 and has a semi-arc structure. The whole structure forms a tubular structure covering the outside of the rotating roller 1. The connecting rod 52 can push the positioning plate 51 to extend or retract. A protrusion 53 is provided on the side of the connecting rod 52 away from the positioning plate 51. The surface of the drive gear 6 is provided with annular array-shaped arc holes 61. The protrusion 53 is slidably limited inside the arc holes 61. Bearings 62 are provided at both ends of the center of the drive gear 6. The bearings 62 are fixed to the inner wall at the center of both ends of the inner cavity of the rotating roller 1, so that the drive gear 6 is located at the center of the inner cavity of the rotating roller 1.

[0032] A damping shaft 71 is installed at the center of the driven gear 7. A knob 72 is provided at the end of the damping shaft 71 away from the driven gear 7. The knob 72 is located outside the rear end of the roller 1. When the operator rotates the knob 72 clockwise at the outer end, the knob 72 will drive the driven gear 7 to rotate through the damping shaft 71. At the same time, the driven gear 7 will drive the driving gear 6 to rotate. The arc-shaped hole 61 on the surface of the driving gear 6 will push the protrusion 53 to move away from the center of the driving gear 6. The protrusion 53 will also drive the connecting rod 52 to extend inward through the through groove 13, so that the positioning plate 51 is away from the roller 1. At this time, the overall diameter will increase. When the knob 72 is rotated counterclockwise, the driven gear 7 will drive the driving gear 6 to rotate counterclockwise, so that the arc-shaped hole 61 pulls the protrusion 53 back. The protrusion 53 will also drive the connecting rod 52 to retract inward through the through groove 13, so that the positioning plate 51 moves back and fits against the surface of the roller 1. This makes it convenient to adjust the size of the entire device according to the inner diameter of different paint buckets.

[0033] See attached document Figure 2-5 The limiting component 8 includes a sleeve 81 and an insertion hole 82 on one side of the sleeve 81. A limiting rod 83 is movably connected inside the sleeve 81. A baffle 84 is installed at one end of the limiting rod 83. The diameter of the baffle 84 is larger than that of the insertion hole 82 to prevent the limiting rod 83 from disengaging from the sleeve 81. A buffer spring 85 is installed at the other end of the baffle 84. The baffle 84 and the buffer spring 85 are located in the inner cavity of the sleeve 81. A pull plate 841 is fixedly connected to one side of the baffle 84. A groove is opened on the surface of the sleeve 81. A movable groove 12 is opened on one side of the rear end of the roller 1. The groove on the surface of the sleeve 81 is aligned with the movable groove 12. The pull plate 841 can extend outward through the movable groove 12, which makes it convenient for the operator to pull the baffle 84 to drive the limiting rod 83 to extend and retract.

[0034] When the limit rod 83 is moved away from the driven gear 7 by the pull plate 841, the limit rod 83 will deform by squeezing the buffer spring 85 through the baffle 84. When the pull plate 841 is released, the buffer spring 85 will rebound the baffle 84 and the limit rod 83. At this time, the limit rod 83 will extend forward through the insertion hole 82 and be inserted into the tooth groove on the surface of the driven gear 7 to prevent the driven gear 7 from rotating on its own.
