Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to an air extraction device for corrugated board processing. Background Technique

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper with a waveform formed by processing through a corrugating roll. Generally, it is divided into two categories: single corrugated board and double corrugated board. Because of its light weight, low price, wide application, simple production, and recyclability, the application of corrugated paper has increased significantly, and it has been comprehensively popularized, promoted, and applied for making packages for various commodities.

[0003] For example, the application number: CN201922059282.3. The utility model relates to the technical field of corrugated paper processing, especially to a dust removal device for corrugated paper production. When the existing corrugated board is cut and processed, a large amount of waste chips and dust will be generated, resulting in more dust inside the cross-cutting machine, which will affect the normal operation of the cross-cutting machine. This solution includes a frame, a cross-cutting machine body is arranged on the frame, a conveyor belt is arranged on the frame, the conveyor belt passes through the cross-cutting machine body, an adsorption component and a collection component are arranged on the cross-cutting machine body. The adsorption component includes a suction hood covering the upper part of the conveyor belt. The body of the suction hood is hollow, and a number of suction holes are opened on the end wall of the suction hood facing the conveyor belt. A ventilation pipe is arranged on the suction hood, and an exhaust fan is arranged on the cross-cutting machine. The exhaust fan is connected to the ventilation pipe. This solution can remove dust inside the cross-cutting machine and reduce the influence of dust on the inside of the cross-cutting machine.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problem that a large amount of waste chips and dust are often generated when the corrugated board is cut and processed. Because there is no good dust removal device in the general cross-cutting machine, there is more dust inside the cross-cutting machine, which will affect the normal operation of the cross-cutting machine and even cause problems such as machine damage. However, in the process of use, although the corrugated paper processing device can remove dust inside the cross-cutting machine, there are also a lot of paper scraps and dust in the space of corrugated paper production. Since the blower continuously sucks in outside air and discharges it into the filter box, and since the exhaust fan is not provided with a dust-proof device, foreign objects are easily introduced into the exhaust fan, which is likely to damage the exhaust fan. Content of the Utility Model

[0005] To solve the problems raised in the above-mentioned background art, the purpose of the present utility model is to provide an air extraction device for corrugated cardboard processing, which has the advantage of auxiliary protection, and solves the problem that although the corrugated paper processing device can remove the dust inside the cross-cutting machine, there will still be a lot of paper scraps and dust in the corrugated paper production space. Since the blower continuously sucks in and discharges the outside air into the filter box, and since the air extraction fan is not provided with a dust-proof device, foreign objects are likely to enter the air extraction fan, which is likely to cause damage to the air extraction fan.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions: An air extraction device for corrugated cardboard processing, including a support frame, a conveyor, a cross-cutting machine, a filter box and a fan. Both sides inside the support frame are fixedly connected to both sides of the left and right sides of the conveyor. The top of the support frame is fixedly connected to the bottom of the cross-cutting machine. The top of the cross-cutting machine is fixedly connected to the bottom of the filter box. The rear side of the top of the cross-cutting machine is movably connected to the bottom of the fan. A connecting plate is fixedly connected to the rear side of the top of the cross-cutting machine. A connecting groove is opened on the front surface of the connecting plate. The connecting groove is communicated with the rear side of the inner wall of the filter box through a conduit. A fixing frame is movably connected to the right side of the fan. A filter cylinder is slidably connected to the inner wall of the fixing frame. An installation component is fixedly connected to the bottom of the fan. A connecting component is fixedly connected to the back surface of the connecting plate.

[0007] Preferably, the installation component includes an installation block. The top of the installation block is fixedly connected to the bottom of the fan. An installation groove is opened on the rear side of the top of the cross-cutting machine. An installation strip is slidably connected to the inner wall of the installation groove. The top of the installation strip is fixedly connected to the bottom of the installation block.

[0008] Preferably, the connecting component includes a connecting block. The front surface of the connecting block is fixedly connected to the back surface of the connecting plate. The inner wall of the connecting block is communicated with the connecting groove. A connecting sleeve is threadedly connected to the surface of the connecting block. The output end of the fan is fixedly connected to a conveying hose. The connecting sleeve is movably sleeved on the surface of the conveying hose. A reinforcing block is fixedly connected to the end of the conveying hose away from the fan.

[0009] Preferably, a limiting groove is opened on the rear side of the top of the cross-cutting machine. A limiting strip is slidably connected to the inner wall of the limiting groove.

[0010] Preferably, a connecting ring is fixedly connected to the right side of the fan. The left side of the surface of the fixing frame is threadedly connected to the inner wall of the connecting ring.

[0011] Preferably, auxiliary strips are fixedly connected to the surface of the connecting sleeve. There are several auxiliary strips and they are evenly distributed in a ring at equal intervals.

[0012] Preferably, a support block is fixedly connected to the back surface of the limit bar, and the support block is trapezoid-shaped.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a fixing frame and a filter cylinder, the present utility model enables the user to easily install the filter cylinder on the right side of the fan using the fixing frame. Then, the filter cylinder can block foreign objects from entering the interior of the fan, thereby extending the service life of the fan. This solves the problem that although the corrugated paper processing device can remove dust inside the cross cutter, there are still a large number of paper scraps and dust in the corrugated paper production space. Since the blower continuously inhales and discharges external air into the filter box, and the blower is not equipped with a dust-proof device, foreign objects are likely to enter the blower, easily causing damage to the blower, achieving an auxiliary protection effect.

[0015] 2. By providing an installation component, when the user needs to install the fan on the top of the cross cutter, first align the installation strip at the bottom of the installation block with the installation groove, and then move the fan towards the right side of the cross cutter, so that the installation strip moves to the rightmost side of the inner wall of the installation groove. The installation groove can restrict the movement direction of the installation strip, making it difficult for the fan to break away from the cross cutter, and then the fan can be installed on the top of the cross cutter, thus achieving the effect of facilitating the user to install the fan.

[0016] 3. By providing a connection component, when the user needs to connect the fan to the filter box, first align the delivery hose at the output end of the fan with the connection block, then move the connection sleeve to the connection block and rotate the connection sleeve to thread the connection sleeve with the connection block. During the connection process between the connection sleeve and the connection block, the rear side of the inner wall of the connection sleeve is easily in contact with the reinforcement block. The reinforcement block restricts the final connection position of the connection sleeve, and at the same time, the reinforcement block is also squeezed by the connection sleeve, making the connection between the delivery hose and the connection plate tighter, thus achieving the effect of assisting the connection between the fan and the connection plate.

[0024] Refer to Figure 2 , the mounting component 10 includes a mounting block 101. The top of the mounting block 101 is fixedly connected to the bottom of the fan 5. A mounting groove 102 is opened on the rear side of the top of the cross cutter 3. The inner wall of the mounting groove 102 is slidably connected to a mounting strip 103. The top of the mounting strip 103 is fixedly connected to the bottom of the mounting block 101.

[0025] As a technical optimization solution of the present utility model, by setting the installation component 10, when the user needs to install the fan 5 on the top of the cross-cutting machine 3, first align the installation strip 103 at the bottom of the installation block 101 with the installation groove 102, and then move the fan 5 towards the right side of the cross-cutting machine 3, so that the installation strip 103 moves to the rightmost side of the inner wall of the installation groove 102. The movement direction of the installation strip 103 can be restricted by the installation groove 102, making it difficult for the fan 5 to break away from the cross-cutting machine 3, and then the fan 5 can be installed on the top of the cross-cutting machine 3, thus achieving the effect of facilitating the user to install the fan 5.

[0026] Reference Figure 3 , the connection component 11 includes a connection block 111. The front surface of the connection block 111 is fixedly connected to the back surface of the connection plate 6. The inner wall of the connection block 111 is communicated with the connection groove 7. The surface of the connection block 111 is threadedly connected with a connection sleeve 112. The output end of the fan 5 is fixedly connected with a delivery hose 113. The connection sleeve 112 is movably sleeved on the surface of the delivery hose 113. One end of the delivery hose 113 far from the fan 5 is fixedly connected with a reinforcement block 114.

[0027] As a technical optimization solution of the present utility model, by setting the connection component 11, when the user needs to connect the fan 5 to the filter box 4, first align the delivery hose 113 at the output end of the fan 5 with the connection block 111, then move the connection sleeve 112 to the connection block 111 and rotate the connection sleeve 112 to threadedly connect the connection sleeve 112 with the connection block 111. During the connection process of the connection sleeve 112 and the connection block 111, the rear side of the inner wall of the connection sleeve 112 is convenient to contact with the reinforcement block 114. The final connection position of the connection sleeve 112 is restricted by the reinforcement block 114. At the same time, the reinforcement block 114 will also be squeezed by the connection sleeve 112, making the connection between the delivery hose and the connection plate 6 tighter, thus achieving the effect of assisting the connection between the fan 5 and the connection plate 6.

[0028] Reference Figure 4 , a limiting groove 12 is opened at the rear side of the top of the cross-cutting machine 3, and a limiting strip 13 is slidably connected to the inner wall of the limiting groove 12.

[0029] As a technical optimization solution of the present utility model, by setting the limiting groove 12 and the limiting strip 13, after the user connects the fan 5 to the cross-cutting machine 3, take out the limiting strip 13 and align it with the limiting groove 12, and then move the limiting strip 13 towards the cross-cutting machine 3, so that the limiting strip 13 completely moves into the interior of the limiting groove 12. The installation groove 102 can be blocked by the limiting strip 13, making it impossible for the installation strip 103 to move out of the installation groove 102, and avoiding the situation that the installation strip 103 breaks away from the installation groove 102 due to the vibration of the fan 5, thus achieving the effect of restricting the movement of the installation strip 103.

[0030] ReferenceFigure 1 , a connecting ring 14 is fixedly connected to the right side of the fan 5, and the left side of the surface of the fixed frame 8 is threadedly connected to the inner wall of the connecting ring 14.

[0031] As a technical optimization scheme of the present utility model, by providing the connecting ring 14, when the user needs to install the filter cartridge 9 on the right side of the fan 5, first align the left side of the fixed frame 8 with the connecting ring 14, and then rotate the fixed frame 8 so that the fixed frame 8 is threadedly connected to the connecting ring 14. The connecting ring 14 can be used to limit the moving direction of the fixed frame 8, so that the fan 5 is connected to the filter cartridge 9, thereby achieving the effect of facilitating the user to install the filter cartridge 9.

[0032] Reference Figure 3 , auxiliary strips 15 are fixedly connected to the surface of the connecting sleeve 112, and a plurality of auxiliary strips 15 are provided and distributed at equal intervals in a ring shape.

[0033] As a technical optimization scheme of the present utility model, by providing the auxiliary strips 15, when the user rotates the connecting sleeve 112, the plurality of auxiliary strips 15 can be used to increase the friction between the user and the connecting sleeve 112, making it easier for the user to rotate the connecting sleeve 112 and avoiding the situation where it is difficult for the user to rotate the connecting sleeve 112 due to slippery hands, thereby achieving the effect of facilitating the user to rotate the connecting sleeve 112.

[0034] Reference Figure 4 , an auxiliary block 16 is fixedly connected to the back surface of the limiting strip 13, and the auxiliary block 16 is trapezoidally arranged.

[0035] As a technical optimization scheme of the present utility model, by providing the auxiliary block 16, when the user needs to pull out the limiting strip 13 from the limiting groove 12, the auxiliary block 16 can be used to increase the contact area between the user and the limiting strip 13. At the same time, the trapezoidal shape of the auxiliary block 16 can be used to increase the friction between the user and the auxiliary block 16, and also provide a point for the user to apply force conveniently, thereby achieving the effect of facilitating the user to move the limiting strip 13.

[0036] Working principle and usage process of the utility model: The fixed frame 8 facilitates the user to install the filter cartridge 9 on the right side of the fan 5. Then, the filter cartridge 9 can block foreign objects from entering the interior of the fan 5, thereby extending the service life of the fan 5. When the user needs to install the fan 5 on the top of the cross-cutting machine 3, first align the installation strip 103 at the bottom of the installation block 101 with the installation groove 102, and then move the fan 5 towards the right side of the cross-cutting machine 3, so that the installation strip 103 moves to the rightmost side of the inner wall of the installation groove 102. The installation groove 102 can limit the moving direction of the installation strip 103, making it difficult for the fan 5 to break away from the cross-cutting machine 3, and thus the fan 5 can be installed on the top of the cross-cutting machine 3. After the user connects the fan 5 to the cross-cutting machine 3, take out the limiting strip 13 and align it with the limiting groove 12, and then move the limiting strip 13 towards the cross-cutting machine 3, so that the limiting strip 13 completely moves into the interior of the limiting groove 12. The limiting strip 13 can cover the installation groove 102, making it impossible for the installation strip 103 to move out of the installation groove 102, avoiding the situation where the installation strip 103 breaks away from the installation groove 102 due to the vibration of the fan 5. When the user needs to connect the fan 5 to the filter box 4, first align the delivery hose 113 at the output end of the fan 5 with the connection block 111, then move the connecting sleeve 112 to the connection block 111 and rotate the connecting sleeve 112 to thread-connect the connecting sleeve 112 with the connection block 111. During the connection process of the connecting sleeve 112 and the connection block 111, the rear side of the inner wall of the connecting sleeve 112 is easy to come into contact with the reinforcement block 114. The reinforcement block 114 restricts the final connection position of the connecting sleeve 112. At the same time, the reinforcement block 114 will also be squeezed by the connecting sleeve 112, making the connection between the delivery hose and the connecting plate 6 tighter, thus achieving the effect of auxiliary protection.

[0037] In summary: For the exhaust equipment used in corrugated cardboard processing, by setting the fixed frame 8 and the filter cartridge 9, the fixed frame 8 facilitates the user to install the filter cartridge 9 on the right side of the fan 5. Then, the filter cartridge 9 can block foreign objects from entering the interior of the fan 5, thereby extending the service life of the fan 5, solving the problem that although the corrugated paper processing device can remove the dust inside the cross-cutting machine, there are still a lot of paper scraps and dust in the corrugated paper production space. Since the blower continuously inhales and discharges the outside air into the filter box, and since the exhaust fan is not equipped with a dust-proof device, foreign objects are likely to enter the interior of the exhaust fan, which is likely to cause damage to the exhaust fan.
