Description

Technical Field

[0001] The utility model relates to the technical field of paper processing, and particularly relates to a paper waste cleaning device. Background Art

[0002] During the process of paper printing and conveying, generally the whole paper is placed on the conveying device and conveyed to the designated processing position via the conveying device. During this process, it is necessary to use a cutting device (usually a trimming knife) to cut off the waste paper edge at the head end of the paper. Since the paper is fully laid on the conveying device, the cut waste paper edge will also be conveyed. In order to clean the waste paper edge on the conveying device, the general method is to add a material removing roller on the basis of the conveying device. After the conveying device drives the waste paper edge to the corresponding position, the material removing roller descends to clean the waste paper edge. After the cleaning is completed, the material removing roller makes an upward movement to reset.

[0003] During the above cleaning process, it is necessary to stop the conveying device to clean the waste paper edge. Each time a new conveying operation is carried out, a cutting operation is required, that is, the total downtime is related to the total number of paper conveyances. If the amount of paper conveyed per unit time is large, the downtime will be longer. The longer downtime will not only delay the production progress, but also make some machines in an idle state, reducing their service life.

[0004] Therefore, we propose a paper waste cleaning device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a paper waste cleaning device to solve the problems in the prior art. By switching the connecting block between the transition state and the flipping state, when blanking is required, the connecting block is in the flipping state, and when normal conveying is carried out, the connecting block is in the transition state. The mutual switching of the two states can complete the corresponding blanking and conveying work without stopping the machine, ensuring the production efficiency and prolonging the working life of the machine.

[0006] To solve the above problems, the utility model provides the following technical solution:

[0007] A paper waste cleaning device includes a first conveying member and a second conveying member arranged in sequence along the conveying direction, and there is a blanking gap between the first conveying member and the second conveying member. A connecting block capable of making a flipping movement is filled in the blanking gap. The connecting block has a transition state and a flipping state. When the connecting block is in the transition state, both ends of the connecting block are flush with the terminal of the first conveying member and the starting end of the second conveying member respectively, and the blanking gap is blocked. When the connecting block is in the flipping state, the connecting block is in an inclined state, and both ends of the connecting block are higher than the terminal of the first conveying member and lower than the starting end of the second conveying member respectively, and the blanking gap is opened.

[0008] As a further solution of the present utility model: The connecting block is movably hinged to the second conveying member, and a driving member for driving the connecting block to perform a flipping action around its hinge point is provided on the second conveying member.

[0009] As a further solution of the present utility model: It further includes a limiting member. The limiting member includes a retaining belt hanging above the first conveying member and the second conveying member, and a limiting area is formed between the retaining belt and the first conveying member and the second conveying member. The limiting area is used to limit the vertical movement of the paper on the first conveying member and the second conveying member.

[0010] As a further solution of the present utility model: It further includes an adjusting cylinder located above the retaining belt, and the retaining belt is installed on the piston end of the adjusting cylinder so that the size of the limiting area is adjustable.

[0011] As a further solution of the present utility model: It further includes a working machine tool for carrying the first conveying member and the second conveying member, and a guide cylinder is fixedly arranged at a position below the blanking gap of the working machine tool.

[0012] As a further solution of the present utility model: The guide cylinder is arranged in a conical shape, and the small-diameter end and the large-diameter end of the guide cylinder are respectively located above and below.

[0013] As a further solution of the present utility model: The driving member is an electric telescopic rod. The electric telescopic rod is arranged on the second conveying member, and the piston rod of the electric telescopic rod is movably connected to the bottom of the connecting block.

[0014] As a further solution of the present utility model: It further includes a suction member. The suction member includes a main pipe arranged on the connecting block, and a negative pressure hose is communicated with the main pipe. A branch pipe is arranged on one side of the connecting block facing the terminal of the first conveying member, and the branch pipe is communicated with the main pipe.

[0015] As a further solution of the present utility model: One side of the connecting block facing the terminal of the first conveying member is arranged in an arc shape. The branch pipes are arranged in multiple numbers, and the multiple branch pipes are arranged in a stepped manner along the arc side of the first conveying member.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. By setting the blanking gap and the connecting block, the connecting block has two working states on the blanking gap. During the process of sequentially conveying waste paper edges and normal paper on the first conveyor to the second conveyor, the connecting block corresponds to the waste paper edge and the normal paper respectively, showing corresponding working states. The two working states are switched according to the types of the waste paper edge and the normal paper, without the need for the first conveyor and the second conveyor to stop, which can not only clean the waste paper edge, but also keep the conveying device running without stopping, ensuring production efficiency and extending the service life of the machine;

[0018] 2. By setting the retaining belt, a limiting area is formed between the retaining belt, the first conveyor and the second conveyor. The limiting area is used to restrict the vertical movement of the paper on the first conveyor and the second conveyor. That is, by setting the limiting area, the longitudinal movement of the paper is restricted, ensuring that the longitudinal movement amplitude of the paper is small and there will be no large swinging on the first conveyor and the second conveyor;

[0019] 3. By setting the adsorbing component, during operation, the connecting block in the flipping state opens the blanking gap, and multiple branch pipes generate negative pressure suction. This negative pressure suction can exert a guiding force on the waste paper edge towards the blanking gap, enabling the waste paper edge to fall into the blanking gap more quickly, accelerating the blanking action of the waste paper edge, shortening the action time, and then the connecting block can change to the transition state faster without affecting the subsequent movement of the normal paper.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0027] As Figures 1-3 shown, a paper waste cleaning device includes a working machine tool 8 and a first conveyor 1 and a second conveyor 2 arranged in sequence along the conveying direction. Among them, both the first conveyor 1 and the second conveyor 2 are arranged on the working machine tool 8. As Figure 1 shown, the first conveyor 1 and the second conveyor 2 are linearly arranged, that is, the two are at a 180-degree angle. In actual use, the first conveyor 1 and the second conveyor 2 can also be arranged at an acute angle or a right angle, etc., and their corresponding layout settings are made according to the installation terrain and the conveying situation. After installing the first conveyor 1 and the second conveyor 2 in the corresponding positions, there is a blanking gap 3 between them, and a guide cylinder 9 is fixedly arranged at the position of the working machine tool 8 below the blanking gap 3. Preferably, the guide cylinder 9 is arranged in a conical shape, and the small-diameter end and the large-diameter end of the guide cylinder 9 are respectively located above and below. The blanking gap 3 is filled with an adapter block 4 that can perform a flipping action. Specifically, the adapter block 4 is movably hinged to the second conveyor 2, and a driving member 5 for driving the adapter block 4 to perform a flipping action around its hinge point is arranged on the second conveyor 2.

[0028] As Figures 2-3 shown, the adapter block 4 has two working states, namely a transition state and a flipping state, and the specific manifestations are as follows:

[0029] (1) When the adapter block 4 is in the transition state, this state can be represented by Figure 2 , at this time, both ends of the adapter block 4 are flush with the terminal of the first conveyor 1 and the starting end of the second conveyor 2 respectively, the blanking gap 3 is blocked, and the adapter block 4 can be used to normally convey the paper on the first conveyor 1 and the second conveyor 2.

[0030] (2) When the adapter block 4 is in the flipping state, this state can be represented by Figure 3 , the adapter block 4 is in an inclined state, and both ends of the adapter block 4 are respectively higher than the terminal of the first conveyor 1 and lower than the starting end of the second conveyor 2, and the blanking gap 3 is opened.

[0031] During normal use, waste paper edges and normal paper are sequentially conveyed from the first conveyor 1 to the second conveyor 2. When the waste paper edge walks to the blanking gap 3, the adapter block 4 is in Figure 3In the shown inverted state, the waste paper edge will fall from the blanking gap 3, and then the driving member 5 is used to drive the connecting block 4 to immediately change to Figure 2 the shown transition state, which is used to enable normal paper to travel onto the second conveying member 2. During this cleaning process, there is no need to stop the machine, and only the working state of the connecting block 4 needs to be changed, which is convenient to use and does not delay the production progress.

[0032] For the driving member 5 used to drive the connecting block 4 to make action changes, the driving member 5 can be an electric telescopic rod, a cylinder, an oil cylinder, etc. When an electric telescopic rod is selected, the electric telescopic rod is arranged on the second conveying member 2, and the piston rod of the electric telescopic rod is movably connected to the bottom of the connecting block 4.

[0033] As Figure 1 shown, in order to ensure that both the first conveying member 1 and the second conveying member 2 can convey the paper smoothly, the present utility model further includes a limiting member. The limiting member includes a retaining belt 6 hanging above the first conveying member 1 and the second conveying member 2, and a limiting area is formed between the retaining belt 6 and the first conveying member 1 and the second conveying member 2. The limiting area is used to limit the vertical movement of the paper on the first conveying member 1 and the second conveying member 2, that is, through the setting of the limiting area, the longitudinal movement of the paper is restricted, ensuring that the longitudinal movement amplitude of the paper is small and there will be no large swinging situation on the first conveying member 1 and the second conveying member 2. At the same time, in order to adapt to different types of paper, an adjusting cylinder 7 can be arranged above the retaining belt 6, and the retaining belt 6 is installed on the piston end of the adjusting cylinder 7 so that the size of the limiting area is adjustable.

[0034] As Figure 4 shown, in order to ensure that the waste paper edge can accurately fall into the blanking gap 3, the present utility model further includes a suction attachment. The suction attachment includes a main pipe 10 arranged on the connecting block 4, and a negative pressure hose 11 is communicated with the main pipe 10. A branch pipe 12 is arranged on one side of the connecting block 4 facing the terminal of the first conveying member 1, and the branch pipe 12 is communicated with the main pipe 10; one side of the connecting block 4 facing the terminal of the first conveying member 1 is set to be arc-shaped, and a plurality of branch pipes 12 are arranged, and the plurality of branch pipes 12 are arranged in a stepped manner along the arc-shaped side of the first conveying member 1. When working, the connecting block 4 in the inverted state opens the blanking gap 3, and a plurality of branch pipes 12 generate negative pressure suction force, and this negative pressure suction force can exert a guiding force on the waste paper edge to move towards the blanking gap 3, so that the waste paper edge can fall into the blanking gap 3 more quickly, accelerating the blanking action of the waste paper edge, shortening the action time, and then the connecting block 4 can change to the transition state faster without affecting the subsequent normal paper walking.

[0035] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as defining the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
