Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging box processing, and specifically relates to an oiling machine for cardboard in paper packaging box processing. Background Technique

[0002] In the processing of paper packaging boxes, the cardboard oiling machine is an important device. It is mainly used to coat a layer of grease or similar protective layer on the surface of the cardboard to improve the waterproof, moisture-proof, wear-resistant, stain-resistant and other properties of the cardboard, so as to protect the items in the packaging box from being damaged during transportation and storage. The cardboard oiling machine is usually connected to the printing, cutting and other processes of the cardboard through an automated production line. After the cardboard enters the oiling machine, the machine will use an oiling roller or a spraying device to evenly coat the special grease or protective coating on the surface of the cardboard.

[0003] Before the cardboard oiling machine in the processing of paper packaging boxes performs oiling processing on the cardboard through the oiling roller, it is usually necessary to evenly add grease or protective coating on the oiling roller. The cardboard of the paper packaging box has different sizes. If the entire oiling roller is fully coated with grease or protective coating, the grease or protective coating in the unused position will be wasted. Therefore, an oiling machine for cardboard in paper packaging box processing is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an oiling machine for cardboard in paper packaging box processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An oiling machine for cardboard in paper packaging box processing, including a frame, a conveyor belt and an oiling roller. A servo motor is installed on the top of one side of the frame. The end of the output shaft of the servo motor is fixedly connected with a positive and reverse threaded screw. Symmetrically arranged screw sleeves are spirally connected to the outside of the positive and reverse threaded screw. A connecting block is fixedly connected to the outside of the screw sleeve. A storage box is fixedly connected to the bottom of the connecting block. A feed pipe with a sealing cover is fixedly connected to one side of the storage box. A through pipe is fixedly connected to the bottom of the storage box. The end of the through pipe away from the storage box is fixedly connected with an arc-shaped installation shell. An outlet pipe is fixedly connected to the inside of the installation shell. An arc-shaped sponge block is fixedly connected to the inside of the installation shell. A guide block is fixedly connected to the outside of the connecting block. A guide rod is slidably connected to the inside of the guide block. Installation blocks are fixedly connected to both ends of the guide rod. A controller electrically connected to the servo motor is installed on the upper end surface of the frame.

[0007] Preferably, the sponge blocks are symmetrically arranged and the sponge blocks are in contact with the oiling roller.

[0008] Preferably, the lower end face of the mounting block is fixedly connected to the upper end face of the frame. A pointer is fixedly connected to the upper end face of the guiding block, and a scale is fixedly connected to the upper end face of the mounting block. The pointers are symmetrically arranged.

[0009] Preferably, one end of the left - hand and right - hand screw rod away from the output shaft of the servo - motor is rotatably connected to a limiting block, and the lower end face of the limiting block is fixedly connected to the upper end face of the frame.

[0010] Preferably, the feed pipe is communicated with the storage box, the storage box is communicated with the through - pipe, the through - pipe is communicated with the installation shell, and the installation shell is communicated with the discharge pipe.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a structure composed of a servo - motor, a left - hand and right - hand screw rod, a nut sleeve, a connecting block, a storage box, a feed pipe, a through - pipe, an installation shell, a discharge pipe, and a sponge block is provided. Remove the sealing cover at the feed pipe, add the paint into the storage box through the feed pipe. The paint in the storage box will flow into the installation shell along the through - pipe, and then enter the sponge block from the discharge pipe at the installation shell. The sponge block contacts the oiling roller. The output shaft of the servo - motor drives the left - hand and right - hand screw rod to rotate. The left - hand and right - hand screw rod drives the nut sleeve to move spirally. The nut sleeve drives the connecting block to move relatively. The connecting block drives the guiding block to move. The guiding block slides relatively with the guiding rod. Under the guidance of the guiding block and the guiding rod, the connecting block drives the storage box, the through - pipe, the installation shell, and the sponge block to move. The driving device in the frame can drive the oiling roller to rotate. Thus, the paint can be evenly applied on the oiling roller through the sponge block. When the total displacement of the connecting block is slightly longer than the cardboard to be oiled, stop starting the servo - motor. In this process, the sponge block acts on the oiling roller and continuously oils it evenly, realizing the ability of the cardboard oiling machine for paper packaging box processing to adjust the oiling range of the oiling roller according to the size of the cardboard, thereby minimizing the waste of paint.

[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0024] A cardboard oiling machine for processing paper packaging boxes, comprising a frame 1, a conveyor belt 2 and an oiling roller 3. A servo motor 4 is installed at the top of one side of the frame 1. The end of the output shaft of the servo motor 4 is fixedly connected to a positive and negative thread screw rod 5. Symmetrically arranged screw sleeves 6 are spirally connected to the outside of the positive and negative thread screw rod 5. A connecting block 7 is fixedly connected to the outside of the screw sleeve 6. A storage box 8 is fixedly connected to the bottom of the connecting block 7. A feed pipe 9 with a sealing cover is fixedly connected to one side of the storage box 8. A through pipe 10 is fixedly connected to the bottom of the storage box 8. The end of the through pipe 10 away from the storage box 8 is fixedly connected to an arc-shaped installation housing 11. An outlet pipe 12 is fixedly connected to the inside of the installation housing 11. A sponge block 13 in an arc shape is fixedly connected to the inside of the installation housing 11. A guide block 14 is fixedly connected to the outside of the connecting block 7. A guide rod 15 is slidably connected to the inside of the guide block 14. Installation blocks 16 are fixedly connected to both ends of the guide rod 15. A controller 19 electrically connected to the servo motor 4 is installed on the upper end surface of the frame 1.

[0025] The sponge blocks 13 are symmetrically arranged and the sponge blocks 13 are in contact with the oiling roller 3. This setting enables the paint entering the sponge blocks 13 to be evenly applied to the outside of the oiling roller 3. The lower end surface of the installation block 16 is fixedly connected to the upper end surface of the frame 1. A pointer 17 is fixedly connected to the upper end surface of the guide block 14. A scale 18 is fixedly connected to the upper end surface of the installation block 16. The pointers 17 are symmetrically arranged. This setting enables the guide block 14 to drive the pointer 17 to move when moving. The pointer 17 points to the scale 18 installed through the installation block 16, so that the moving length of the guide block 14 and the connecting block 7 can be judged through the scale 18. The end of the positive and negative thread screw rod 5 away from the output shaft of the servo motor 4 is rotatably connected to a limit block 20. The lower end surface of the limit block 20 is fixedly connected to the upper end surface of the frame 1. This setting enables the output shaft of the servo motor 4 to drive the positive and negative thread screw rod 5 to rotate stably. The feed pipe 9 is communicated with the storage box 8, the storage box 8 is communicated with the through pipe 10, the through pipe 10 is communicated with the installation housing 11, and the installation housing 11 is communicated with the outlet pipe 12. This setting enables the sealing cover at the feed pipe 9 to be removed, and the paint is added to the storage box 8 through the feed pipe 9. The paint in the storage box 8 will enter the installation housing 11 along the through pipe 10, and then enter the sponge blocks 13 from the outlet pipe 12 at the installation housing 11.

[0026] Workflow: All the electrical appliances in this utility model are provided with an external power supply or a built-in battery. Before oiling the cardboard, the servo motor 4 is started through the controller 19. The output shaft of the servo motor 4 drives the left and right hand threaded lead screw 5 to rotate. The left and right hand threaded lead screw 5 rotates relative to the limit block 20. The left and right hand threaded lead screw 5 drives the nut sleeve 6 to screw, so that the nut sleeve 6 moves in the direction of approaching each other. The nut sleeve 6 drives the connecting block 7 to move relatively. The connecting block 7 drives the guide block 14 to move. The guide block 14 slides relative to the guide rod 15. Under the guidance of the guide block 14 and the guide rod 15, the connecting block 7 drives the material storage box 8, the through pipe 10, the installation shell 11 and the sponge block 13 to move. When the installation shells 11 contact each other, the servo motor 4 is stopped. Then, the sealing cover at the feed pipe 9 is removed, and the paint is added to the material storage box 8 through the feed pipe 9. The paint in the material storage box 8 will enter the installation shell 11 along the through pipe 10, and then enter the sponge block 13 from the discharge pipe 12 at the installation shell 11. The sponge block 13 contacts the oiling roller 3. The frame 1 is arranged on both sides of the oiling roller 3. The driving device in the frame 1 can drive the oiling roller 3 to rotate, so that the paint can be evenly applied on the oiling roller 3 through the sponge block 13. When the device in the frame 1 drives the oiling roller 3 to rotate, the servo motor 4 is started through the controller 19, so that the output shaft of the servo motor 4 can drive the nut sleeve 6 to move in the direction of moving away from each other. The guide block 14 will drive the pointer 17 to move when moving. The pointer 17 points to the scale 18 installed through the installation block 16, so that the moving length of the guide block 14 and the connecting block 7 can be judged through the scale 18. When the moving length of the connecting block 7 is slightly longer than the cardboard to be oiled, the output shaft of the servo motor 4 is rotated in the reverse direction through the controller 19, so that the total maximum displacement of the connecting block 7 is slightly longer than the cardboard to be oiled. During this process, the sponge block 13 acts on the oiling roller 3 and continuously oils it evenly. After the oiling roller 3 is oiled, the cardboard is placed on the conveyor belt 2 at the bottom of the oiling roller 3, and the oiling roller 3 will evenly apply the paint on the cardboard.
