Description

Technical Field

[0001] The utility model relates to the technical field of cardboard slotting, in particular to a cardboard slotting waste collection device. Background Technique

[0002] Slotting machines are used in the production and processing of cardboard. They are specialized machines for slotting various boards such as industrial cardboard, grey cardboard, and density board. Generally, they include a cardboard conveying mechanism, a wire pressing mechanism, a cutting mechanism, etc., and have the characteristics of high precision, high speed, and durable cutting tools.

[0003] Most of the existing cardboard slotting machines do not have a waste collection device. Usually, after slotting, workers need to manually collect the generated waste together, which increases the labor intensity of workers and the cleaning speed is not high enough, affecting the production efficiency of cardboard. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a cardboard slotting waste collection device is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A cardboard slotting waste collection device includes a throat pipe. One end of the throat pipe is fixedly connected with a contraction pipe. The end of the contraction pipe away from the throat pipe is fixedly connected with an air inlet pipe. Two groups of first mounting brackets are fixedly connected inside the air inlet pipe. Two groups of first motors are fixedly connected in the middle of the first mounting brackets, and the output ends of the first motors face the contraction pipe. The output ends of the first motors are fixedly connected with fan blades. The end of the throat pipe away from the contraction pipe is fixedly connected with a diffuser pipe. The end of the diffuser pipe away from the throat pipe is fixedly connected with an extension pipe. The end of the extension pipe away from the diffuser pipe is fixedly connected with a second filter screen. The lower end of the throat pipe is fixedly connected with an absorption pipe.

[0006] As a further description of the above technical scheme:

[0007] One end of the air inlet pipe away from the contraction pipe is fixedly connected with a first filter screen, and the first filter screen can prevent dust from entering the inside of the air inlet pipe.

[0008] As a further description of the above technical scheme:

[0009] One side of the upper end of the absorption pipe is fixedly connected with a second mounting bracket. A second motor is fixedly connected in the middle of the second mounting bracket. The output end of the second motor is fixedly connected with a synchronous pulley, and the synchronous pulley is driven to rotate by the second motor.

[0010] As a further description of the above technical scheme:

[0011] A rotating shaft is rotatably connected to the middle of the absorption tube. A plurality of blades are fixedly connected to the surface of the rotating shaft. One end of the rotating shaft passing through the absorption tube is fixedly connected to a synchronous pulley, and the two synchronous pulleys are meshed with each other. The second motor drives the rotating shaft to rotate through the two synchronous pulleys, so that the blades cut the waste material entering the interior of the absorption tube, thereby facilitating the collection of the waste material.

[0012] As a further description of the above technical solution:

[0013] Mounting seats are fixedly connected to both ends on both sides of the lower end of the absorption tube. Fixed shafts are fixedly connected to the lower ends of the two mounting seats on the same side of the absorption tube. Rubber rollers are rotatably connected to the surface of the fixed shafts. The rubber rollers are in contact with the cardboard. When the cardboard moves, it will drive the rubber rollers to rotate, thereby reducing the friction between the absorption tube and the cardboard, and at the same time making the sealing between the cardboard and the absorption tube better.

[0014] As a further description of the above technical solution:

[0015] Fixing plates are fixedly connected to both sides of the lower end of the extension tube. Sliding plates are slidably connected to the interiors of the fixing plates. Collecting grooves are fixedly connected to the opposite ends of the two sliding plates, and the collecting grooves are located at the lower end of the extension tube. The collecting grooves are communicated with the interior of the extension tube. Through the fixing plates, the sliding plates can be clamped inside the fixing plates, so as to install the collecting grooves below the extension tube.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, first of all, the device is installed on a grooving machine. The lower part of the absorption tube is on the conveyor belt of the grooving machine, and the length of the absorption tube is the same as the width of the cardboard. The two first motors drive the fan blades to rotate, so that the outside air enters the air inlet tube and flows along the contraction tube into the throat tube, increasing the air flow rate and decreasing the pressure in the throat tube. The air in the throat tube flows at high speed towards the diffuser tube and the extension tube, causing the air inside the absorption tube to flow at high speed towards the throat tube, reducing the internal pressure. The waste material on the cardboard passing through the lower end of the absorption tube will be absorbed into the interior. After being crushed by the blades, the crushed waste material will follow the air into the collecting groove, thereby completing the collection of the waste material. The device crushes and collects the waste material on each cardboard passing through the absorption tube, so that the collection of the waste material is completed during the movement of the cardboard, improving the efficiency of waste material collection and reducing the production cost.

[0018] 2. In the present utility model, the rubber roller is in contact with the cardboard. When the cardboard moves, the rubber roller will rotate accordingly, thereby reducing the friction between the rubber roller and the cardboard, making it smoother for the cardboard to pass through the absorption tube from the lower end. At the same time, the sealing performance between the cardboard and the absorption tube is improved, so that the outside air can only enter the interior of the absorption tube through both ends of the absorption tube and the slots opened on the cardboard, thereby increasing the air flow rate passing through the cardboard and enabling the air to drive the waste materials in the slots to move upward.

[0019] 3. In the present utility model, workers do not need to manually clean the waste materials. After the waste materials in the collection tank are full, workers only need to remove the collection tank from the extension tube and insert the sliding plate on the new collection tank into the fixed plate, thereby installing the collection tank below the extension tube to complete the work, reducing the labor intensity.

[0029] Referring to Figures 1-5 , an embodiment provided by the present utility model: a cardboard slotting waste collection device, including a throat pipe 3, one end of the throat pipe 3 is fixedly connected to a contraction pipe 2, the end of the contraction pipe 2 far from the throat pipe 3 is fixedly connected to an air inlet pipe 1, two groups of first mounting brackets 9 are fixedly connected inside the air inlet pipe 1, two groups of first motors 10 are fixedly connected to the middle of the first mounting brackets 9, and the output end of the first motor 10 faces the contraction pipe 2. A fan blade 11 is fixedly connected to the output end of the first motor 10. The end of the throat pipe 3 far from the contraction pipe 2 is fixedly connected to a diffuser pipe 5, the end of the diffuser pipe 5 far from the throat pipe 3 is fixedly connected to an extension pipe 6, the end of the extension pipe 6 far from the diffuser pipe 5 is fixedly connected to a second filter screen 20, and the lower end of the throat pipe 3 is fixedly connected to an absorption pipe 4.

[0030] Both sides of the lower end of the extension pipe 6 are fixedly connected with fixing plates 21. Sliding plates 22 are slidably connected inside the fixing plates 21. Opposite ends of the two groups of sliding plates 22 are fixedly connected with collecting grooves 7, and the collecting grooves 7 are located at the lower end of the extension pipe 6. The collecting grooves 7 and the inside of the extension pipe 6 are connected. Through the fixing plates 21, the sliding plates 22 can be stuck inside the fixing plates 21, so as to install the collecting grooves 7 below the extension pipe 6. Both ends of both sides of the lower end of the absorption pipe 4 are fixedly connected with mounting seats 17. Fixed shafts 18 are fixedly connected to the lower ends of the two groups of mounting seats 17 on the same side of the absorption pipe 4. Rubber rollers 19 are rotatably connected to the surfaces of the fixed shafts 18. The rubber rollers 19 are attached to the cardboard. When the cardboard moves, it will drive the rubber rollers 19 to rotate, thereby reducing the friction between the absorption pipe 4 and the cardboard and making the sealing between the cardboard and the absorption pipe 4 better. A rotating shaft 14 is rotatably connected to the middle of the absorption pipe 4. A number of blades 15 are fixedly connected to the surface of the rotating shaft 14. One end of the rotating shaft 14 passing through the absorption pipe 4 is fixedly connected with a synchronous pulley 16, and the two synchronous pulleys 16 are meshed with each other. The second motor 13 drives the rotating shaft 14 to rotate through the two synchronous pulleys 16, so that the blades 15 cut the waste material entering the inside of the absorption pipe 4, thus facilitating the collection of waste material. One side of the upper end of the absorption pipe 4 is fixedly connected with a second mounting bracket 12. A second motor 13 is fixedly connected to the middle of the second mounting bracket 12. The output end of the second motor 13 is fixedly connected with a synchronous pulley 16. The second motor 13 drives the synchronous pulley 16 to rotate. One end of the air inlet pipe 1 far from the contraction pipe 2 is fixedly connected with a first filter screen 8. Through the first filter screen 8, dust can be prevented from entering the inside of the air inlet pipe 1.

[0031] Working principle: The device is installed on the cardboard slotting device through an externally connected mounting bracket. The sliding plate 22 is inserted into the fixed plate 21, so that the collection tank 7 is installed below the extension pipe 6. The second motor 13 drives the rotation of the rotating shaft 14 through the synchronous pulley 16 and the synchronous belt. The rotating shaft 14 drives the rotation of the blade 15, enabling the outside air to pass through the first filter screen 8 and enter the air inlet pipe 1. The air flows along the contraction pipe 2 into the throat pipe 3 and flows along the throat pipe 3 towards the diffuser pipe 5. The air flowing into the diffuser pipe 5 finally enters the extension pipe 6 and flows to the outside from the second filter screen 20. During the process of the air flowing in the throat pipe 3, the rubber roller 19 is in contact with the cardboard. When the cardboard moves, it will drive the rotation of the rubber roller 19, thereby reducing the friction between the absorption pipe 4 and the cardboard, making the cardboard pass more smoothly under the lower end of the absorption pipe 4, and at the same time making the sealing between the cardboard and the absorption pipe 4 better, so that the outside air can only enter the absorption pipe 4 from both ends of the absorption pipe 4 and the slots opened on the cardboard, thereby increasing the air flow through the slots opened on the cardboard, enabling the air to drive the waste in the slots to move upward. When the waste passes through the middle of the rotating shaft 14, it is chopped by the blade 15, so that the chopped waste flows along the air from the throat pipe 3 through the diffuser pipe 5 into the extension pipe 6. The waste is blocked by the second filter screen 20 and finally falls into the collection tank 7. When the waste in the collection tank 7 accumulates too much, the sliding plate 22 can be pulled out from the fixed plate 21 to pour out the waste, and then the collection tank 7 is installed back below the extension pipe 6.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
