Description

Technical Field

[0001] The present invention relates to the technical field of sheet polishing, and particularly relates to an equipment for polishing and waxing the surface of packaging box sheets. Background Art

[0002] In the processing industry of packaging box sheets, the polishing and waxing treatment of the sheet surface is a crucial link, which is directly related to the appearance quality, durability and market acceptance of the packaging box. However, a series of problems exist in the traditional polishing and waxing equipment during the processing, which limit the further improvement of production efficiency and product quality.

[0003] Firstly, during the waxing process, the wax liquid is often difficult to be evenly applied on the sheet surface, resulting in poor waxing effect. The wax layer is too thick in some areas, too thin in some areas, and there are even areas without waxing. This uneven waxing treatment not only affects the aesthetics of the sheet, but also may reduce its waterproof and moisture-proof properties. In addition, most equipment requires manual pushing of the sheet into the polishing and waxing area, which not only increases the labor intensity of the operator, but also may cause the sheet to shift in position due to improper operation, affecting the polishing and waxing effect. At the same time, manual pushing of the sheet also limits the automation degree of the equipment and reduces the production efficiency. After processing one area, it is necessary to manually adjust the position of the sheet for polishing and waxing treatment in the next area, which is not only time-consuming and laborious, but also may result in poor treatment effect due to inaccurate position adjustment. Summary of the Invention

[0004] The present invention relates to an equipment for polishing and waxing the surface of packaging box sheets, aiming to solve the problems of uneven distribution of wax liquid, unreasonable sequence of waxing and polishing treatment, and backward sheet conveying mode existing in the traditional polishing and waxing equipment when processing packaging box sheets.

Above the middle between the second conveying roller and the third conveying roller is a pressing roller. The controller is hung on the outer wall of the plate feeding frame to control each electrical component. The packaging box plate slides through under the pressing roller from the first conveying roller and reaches between the driving rod and the driven roller for polishing and waxing.

[0007] Optionally, a pressing and moving hole is vertically opened on the plate feeding frame at the position corresponding to the pressing roller. The rotating shafts at both ends of the pressing roller are slidably placed in the pressing and moving holes. A pressing seat is arranged on the side wall of the plate feeding frame inside the pressing and moving hole. A pressing rod is vertically slidably arranged in the pressing seat. The lower end of the pressing rod is fixedly connected with a sleeve block. The sleeve block is rotatably sleeved with the rotating shaft of the pressing roller. One side wall of the sleeve block is always tangent to the side wall of the plate feeding frame. A third spring for always providing a downward thrust to the sleeve block is arranged on the pressing rod.

[0008] Optionally, an enlarged companion retaining disc is fixedly arranged at the outer end of the driven gear.

[0009] Optionally, retaining rings for preventing the driving gears from coming off are respectively fixedly arranged at both ends of the spline shaft. A first spring is sleeved on the spline shaft between the driving gear and the retaining ring at the outer end.

A follower gear is fixedly provided at the upper end of the uniform distribution shaft. The follower gear is always engaged with the rack. A uniform distribution impeller is fixedly provided at the lower end of the uniform distribution shaft. The blades of the uniform distribution impeller are sponge cloth. During the process of the polishing and waxing moving module reciprocating with the reciprocating lead screw, the follower gear drives the uniform distribution shaft so that the uniform distribution impeller rotates reciprocally.

[0011] Optionally, the tooth groove length of the rack is greater than the wheel thickness of the follower gear.

[0012] Optionally, the upper groove wall of the card slot of the directional suspension block is a structure that extends outward, and an atomizing nozzle is fixedly provided on the extended part. The lower end of the atomizing nozzle faces the uniform distribution impeller.

[0014] Optionally, when the motor works, the driving rod rotates, and the reciprocating lead screw drives the polishing and waxing moving module to move left and right reciprocally, synchronously driving the grinding machine and the uniform distribution impeller to polish and evenly spray wax liquid. When the polishing and waxing moving module moves to the end position, the contact rod squeezes the driving gear on the corresponding side to move outward, and the corresponding first spring is compressed. The driving gear meshes with the driven gear below and bites in. The driven roller rotates to drive the sheet material to advance.

The blades of the evenly distributed impeller are made of sponge cloth, which has good liquid absorption and uniform spraying properties. When the polishing and waxing moving module moves to a specific position, the atomizing nozzle starts to work, and the wax liquid in the wax liquid storage tank is transported to the nozzle through a pump and a delivery hose, and then atomized and sprayed onto the evenly distributed impeller. During the rotation of the evenly distributed impeller, the wax liquid is evenly applied to the surface of the board, realizing the pre-treatment of waxing, making the wax liquid evenly distributed, facilitating the full polishing and waxing treatment by the grinding machine. The grinding machine installed on the movable seat moves along with the polishing and waxing moving module, and polishes the surface of the board between the driving rod and the driven roller. During this process, the saw blade of the grinding machine rotates, removing the defects on the surface of the board through physical friction and evenly grinding the wax liquid into the board, making its surface smoother. It can realize the pre-spraying and even distribution of the wax liquid first and then the polishing and waxing treatment, which can effectively protect the board.

[0016] When the polishing and waxing moving module moves to the end position, the touch rod will squeeze the driving gear on the corresponding side, causing it to move outward and mesh with the driven gear below. At this time, the driven roller rotates under the drive of the driving gear, and then drives the board to move forward a distance equal to the diameter of the saw blade of the grinding machine. When the driving gear is separated from the driven gear, the driven roller stops rotating and the board stops moving, and the polishing and waxing treatment of the next area of the board is carried out, which can realize the automatic advancement and full waxing treatment of the board.

[0023] Among them, the first conveying roller 3, the second conveying roller 4, the third conveying roller 5 and the driven roller 6 are horizontally installed from one end of the sheet feeding rack 1 to the other end in sequence.

A large distance interval is left between the first conveying roller 3 and the second conveying roller 4. Edge guide wheels 102 for guiding the straight travel of the sheet are respectively arranged on the left and right inner side walls of the sheet feeding rack 1 at the positions between the first conveying roller 3 and the second conveying roller 4. Above the middle between the second conveying roller 4 and the third conveying roller 5 is a pressure roller 14. The controller 2 is hung on the outer wall of the sheet feeding rack 1 to control each electrical component. The packaging box sheet slides through below the pressure roller 14 from the first conveying roller 3 and travels to between the driving rod 8 and the driven roller 6 for polishing and waxing.

[0024] Among them, a pressing movable hole 101 is vertically opened on the sheet feeding rack 1 at the position corresponding to the pressure roller 14. The rotating shafts at both ends of the pressure roller 14 are slidably placed in the pressing movable hole 101.

[0027] Among them, four contact rods 901 are distributed on each side centered on the reciprocating lead screw 801, and the ends of the contact rods 901 are smooth ball head structures; one side wall of one end of the movable seat 902 is in vertical sliding tangency with the polishing and waxing moving module 9, and the upper end of the movable seat 902 extends horizontally to one side of the polishing and waxing moving module 9 as a horizontal extension plate. Two guide rods 904 are vertically provided at the upper end of the polishing and waxing moving module 9. The guide rods 904 vertically pass through the extension plate. Plugs are provided at the upper ends of the guide rods 904, and a second spring 905 is provided on the guide rods 904 between the plugs and the extension plate.

During the process of the polishing and waxing moving module 9 reciprocatingly moving along with the reciprocating lead screw 801, the follower gear 907 drives the distribution shaft 906 to make the distribution impeller 908 rotate reciprocally.

[0028] Among them, the tooth groove length of the rack 11 is greater than the wheel thickness of the follower gear 907, which can always ensure that the follower gear 907 is in a meshed connection state during the up and down movement, ensuring the continuity of the transmission.

[0029] Embodiment 2, on the basis of Embodiment 1, the upper end wall of the card slot 9091 of the directional suspension block 909 is a structure extending outward, and an atomizing nozzle 1303 is fixedly provided on the extended part. The lower end of the atomizing nozzle 1303 faces the distribution impeller 908.

[0030] Among them, the wax liquid storage tank 13 is hung on the side wall of one end of the feeding plate frame 1 away from the motor 7. A pump 1301 for pumping and sending wax liquid is provided on the wax liquid storage tank 13. A delivery hose 1302 is connected between the pump 1301 and the atomizing nozzle 1303. The delivery hose 1302 is spirally wound around the wire guiding rod 12.

[0031] Among them, when the motor 7 works, the driving rod 8 rotates, the reciprocating lead screw 801 drives the polishing and waxing moving module 9 to reciprocate left and right, synchronously driving the grinding machine 903 and the distribution impeller 908 to polish and evenly spray wax liquid. When the polishing and waxing moving module 9 moves to the end position, the contact rod 901 squeezes the driving gear 803 on the corresponding side to move outward, and the corresponding first spring 804 is compressed. The driving gear 803 meshes and engages with the lower driven gear 601. The driven roller 6 rotates to drive the sheet material to advance. Until the driving gear 803 is separated from the driven gear 601, the driven roller 6 stops rotating, and the sheet material advances a distance equal to the diameter of one saw blade. The polishing and waxing moving module 9 drives the grinding machine 903 and the distribution impeller 908 to continue polishing and evenly spraying wax liquid.

[0032] Working principle: After the device starts, the motor 7 begins to work, and its power is transmitted to the drive rod 8 through the transmission mechanism. The middle part of the drive rod 8 is a reciprocating lead screw 801, and the polishing and waxing moving module 9 installed on the reciprocating lead screw 801 can move left and right reciprocally along the lead screw. During the movement, the directional suspension block 909 at one end of the polishing and waxing moving module 9 slides stably along the rail 10, ensuring the accuracy and stability of the movement path.

[0033] The evenly distributed shaft 906 realizes synchronous rotation with the reciprocating movement of the polishing and waxing moving module 9 through the meshing of the follower gear 907 and the rack 11. The blades of the evenly distributed impeller 908 are made of sponge cloth, with good liquid absorption and uniform spraying properties. When the polishing and waxing moving module 9 moves to a specific position, the atomizing nozzle 1303 starts to work, and the wax liquid in the wax liquid storage tank 13 is transported to the nozzle through the pump 1301 and the delivery hose 1302, and is atomized and sprayed onto the evenly distributed impeller 908. During the rotation of the evenly distributed impeller 908, the wax liquid is evenly smeared on the surface of the board, realizing the pre-treatment of waxing, making the wax liquid evenly distributed, and facilitating the full polishing and waxing treatment by the polishing machine 903.

[0034] At the same time, the polishing machine 903 installed on the movable seat 902 polishes the surface of the board between the drive rod 8 and the driven roller 6 as the polishing and waxing moving module 9 moves. During this process, the saw blade of the polishing machine 903 rotates, removing the defects on the surface of the board through physical friction and evenly polishing the wax liquid into the board, making its surface smoother.

[0035] In addition, when the polishing and waxing moving module 9 moves to the end position, the touch rod 901 will squeeze the corresponding side drive gear 803, causing it to move outward and mesh with the lower driven gear 601. At this time, the driven roller 6 rotates driven by the drive gear 803, and then drives the board to move forward a distance equal to the diameter of the saw blade of the polishing machine 903. When the drive gear 803 separates from the driven gear 601, the driven roller 6 stops rotating and the board stops moving, and the polishing and waxing treatment of the next area of the board is carried out, realizing the automatic advancement and full waxing treatment of the board.

[0036] During the whole working process, the controller 2 is responsible for controlling the start, stop of the motor 7 and the working state of the wax liquid pump 1301, ensuring the stable operation and efficient processing of the device. At the same time, through the adjustment of the pressure roller 14 by the pressure rod 1402 and the third spring 1404, the appropriate pressure on the board is always maintained, ensuring the stability of the board during transportation and the polishing and waxing effect.

[0037] In this article, the following points need to be noted: 1. The attached drawings of the embodiments of the present invention only relate to the structures involved in the embodiments of the present invention, and other structures can refer to the general design.

[0038] 2. Without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0039] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
