Description

Technical Field

[0001] This invention relates to the field of gypsum board cutting technology, and more specifically to a negative pressure slag collection gypsum board cutting system. Background Technology

[0002] The dried and shaped gypsum boards are cut into different specifications and models as needed by a cutting machine. After the cut gypsum boards are packaged and inspected, the final products can be transported and sold.

[0003] However, during the cutting process, the cutter generates a large amount of waste residue while cutting the gypsum board. This waste residue not only splashes but also spills onto the surface of the gypsum board. The gypsum board with the waste residue stuck to it is easily crushed by the subsequent belt and roller conveyor, causing the residue to stick tightly to the surface and affecting the quality of the finished product.

[0004] Although existing technologies clean the surface of gypsum board after cutting using equipment such as roller brushes, the roller brushes can scratch the surface of the gypsum board in order to remove material residue. At the same time, they cannot completely clean the material residue adhering to the surface of the gypsum board, resulting in scratches and small gypsum board residues on the surface of the gypsum board after drying, which greatly affects the appearance quality of the product. Summary of the Invention

[0005] The purpose of this invention is to provide a negative pressure slag collection gypsum board cutting system to solve the technical problem of difficult and non-destructive cleaning of slag adhering during gypsum board cutting in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A negative pressure slag collection gypsum board cutting system includes a rotary cutting mechanism and a rotary cutting support position. Two sets of cutters are arranged in parallel on the rotary cutting support position. The gypsum board is moved between the two sets of cutters by a conveying mechanism for cutting. A collection cover is fixedly installed on the outer wall of the rotary cutting mechanism, and a rotating channel is fixedly installed on the outer wall of the collection cover. The rotating channel rotates synchronously with the rotary cutting mechanism with the axis of the rotary cutting mechanism as the center. One end of the rotating channel is connected to a negative pressure fan through a negative pressure pipe to form a negative pressure collection structure. The two ends of the rotating channel are respectively connected to the collection hood and the negative pressure pipe. A diversion loading position is provided on the rotating channel, and a slag recovery channel is provided on the diversion loading position. A slag recovery pool is provided at the output end of the negative pressure pipe. The slag enters the rotating channel, is diverted by the slag recovery channel, and is sent to the slag recovery pool.

[0007] In a preferred embodiment of the present invention, the slag recovery channel is vertically inserted through one end of the negative pressure pipe and connected to the negative pressure fan, and a filter is provided at the connection position between the slag recovery channel and the negative pressure fan; The slag recycling channel is constructed using a cloth bag slag recycling channel.

[0008] In a preferred embodiment of the present invention, the discharge end of the rotating channel is rotatably connected to the feed end of the negative pressure pipe, and the rotating channel has a Z-shaped structure. The rotary channel has a disturbance component fixedly installed at the discharge end. The disturbance component is movably inserted through the inner wall of the slag recovery channel, and one end of the disturbance component is rotatably connected to the discharge end of the slag recovery channel.

[0009] In a preferred embodiment of the present invention, one end of the disturbance component is rotatably connected to the negative pressure pipe via a rotating ring. The rotating ring is provided with a sliding groove that matches the disturbance component. The rotating channel drives the disturbance component to rotate on the inner wall of the slag recovery channel and to move and abut against the slag recovery channel.

[0010] As a preferred embodiment of the present invention, the disturbance component includes a disturbance rod, one end of which is provided with a cleaning rod that movably abuts against the filter sheet, and the outer wall of the cleaning rod movably abuts against one side of the filter sheet; The outer wall of the disturbance rod is provided with multiple sets of protrusions at equal intervals. The height of the protrusions increases from the end near the rotating channel to the end near the negative pressure pipe. When the disturbance rod rotates, it drives the protrusions to squeeze the inner wall of the slag recovery channel, causing one end of the slag recovery channel to expand into a trumpet-shaped structure. A brush is provided on the side of the cleaning rod that contacts the filter plate.

[0011] As a preferred embodiment of the present invention, the slag recovery channel is provided with a conveying pipe connected to the slag recovery pool at one end near the negative pressure fan, and a recovery port is provided at the connection position between the slag recovery channel and the conveying pipe.

[0012] In a preferred embodiment of the present invention, the outer wall of the rotary cutting mechanism is provided with a frame, and the frame is provided with an annular slide rail with the rotary cutting mechanism as the center. A main bearing is provided at one end of the rotary cutting mechanism, and auxiliary bearings are provided on the outer wall of the rotating channel and the inner wall of the annular slide rail. The main bearing is slidably connected to the annular slide rail through the auxiliary bearings.

[0013] In a preferred embodiment of the present invention, the collecting cover has a semi-enclosed structure on the outer wall of the cutter, and the bottom end of the collecting cover is in movable contact with the plasterboard. An extended nozzle is movably provided at the bottom of the collection hood. A spring is provided at the contact position between the extended nozzle and the collection hood to form an elastic telescopic structure. An anti-wear pad is provided on the lower surface of the extended nozzle.

[0014] Compared with the prior art, the present invention has the following advantages: This invention constructs a negative pressure collection structure through a movable contact mechanism. While the gypsum board is being rotary-cut, the collection hood abuts against the board surface to form a closed space and uses negative pressure kinetic energy to collect the slag. This allows for the collection and processing of slag during the cutting process. The collected slag is filtered, and the rotary cutting mechanism drives the agitation component to rotate and guide the slag, reducing slag blockage at the negative pressure port and its impact on the collection effect. At the same time, fine dust is separated from the slag by the negative pressure fan and discharged, facilitating the recycling of gypsum slag and reducing costs and losses.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 and Figure 2 As shown, the present invention provides a gypsum board cutting system with negative pressure slag collection, including a rotary cutting mechanism 10 and a rotary cutting carrier. Two sets of cutters 11 are arranged in parallel on the rotary cutting carrier. The gypsum board is moved between the two sets of cutters 11 by a conveying mechanism 12 for cutting. A collection cover 20 is fixedly provided on the outer wall of the rotary cutting mechanism 10. A rotating channel 30 is fixedly installed on the outer wall of the collection cover 20. The rotating channel 30 rotates synchronously with the rotary cutting mechanism 10 with the axis of the rotary cutting mechanism 10 as the center. One end of the rotating channel 30 is connected to the negative pressure fan 50 through the negative pressure pipe 40 to form a negative pressure collection structure. The two ends of the rotating channel 30 are respectively connected to the collection hood 20 and the negative pressure pipe 40. The rotating channel 30 is provided with a diversion loading position, and a slag recovery channel 31 is provided on the diversion loading position. A slag recovery pool 34 is provided at the output end of the negative pressure pipe 40. The slag enters the rotating channel 30 and is diverted by the slag recovery channel 31 before being sent to the slag recovery pool 34.

[0020] This invention constructs a negative pressure collection structure through a movable contact mechanism. While the gypsum board is being rotary-cut, the collection hood abuts against the board surface to form a closed space and uses negative pressure kinetic energy to collect the slag. This allows for the collection and processing of slag during the cutting process. The collected slag is filtered, and the rotary cutting mechanism drives the agitation component to rotate and guide the slag, reducing slag blockage at the negative pressure port and its impact on the collection effect. At the same time, fine dust is separated from the slag by the negative pressure fan and discharged, facilitating the recycling of gypsum slag and reducing costs and losses.

[0021] The collection hood 20 surrounds both sides of the cutter 11 and forms a relatively closed state with contact with the panel. While the cutter 11 is cutting, the collection hood 20 is driven to enclose and seal the cutting position. The negative pressure fan 50 provides negative pressure kinetic energy through the rotating channel 30 to the collection hood 20. This can suck the debris generated during cutting into the collection hood 20 and process it in a centralized manner, which can reduce the problem of debris sticking to the board surface during cutting and affecting the board surface quality.

[0022] like Figure 2 and Figure 3 As shown, the slag recovery channel 31 is vertically inserted through one end of the negative pressure pipe 40 and connected to the negative pressure fan 50. A filter is provided at the connection position between the slag recovery channel 31 and the negative pressure fan 50. The slag recycling channel 31 is constructed using a cloth bag slag recycling channel.

[0023] The debris is isolated through the slag recovery channel 31, and the debris and dust are separated and treated separately. The debris can be recycled and reused. The dust in the air is filtered through the filter and discharged by the negative pressure fan 50.

[0024] like Figure 2 As shown, the discharge end of the rotating channel 30 is rotatably connected to the feed end of the negative pressure pipe 40, and the rotating channel 30 has a Z-shaped structure; The rotary channel 30 has a disturbance component 32 fixedly installed at the discharge end. The disturbance component 32 is movably inserted through the inner wall of the slag recovery channel 31, and one end of the disturbance component 32 is rotatably connected to the discharge end of the slag recovery channel 31.

[0025] The negative pressure channel is formed by connecting the negative pressure pipe 40 and the collection cover 20 through the rotating channel 30. At the same time, the collection cover 20 drives the rotating channel 30 to rotate together. While the cutter 11 is cutting, it drives the disturbance component 32 to rotate on the inner wall of the slag recovery channel 31.

[0026] like Figure 2 and Figure 3 As shown, one end of the disturbance component 32 is rotatably connected to the negative pressure pipe 40 through a rotating ring 41. The rotating ring 41 has a sliding groove that matches the disturbance component 32. The rotating channel 30 drives the disturbance component 32 to rotate on the inner wall of the slag recovery channel 31 and to move and abut against the slag recovery channel 31.

[0027] While the cutter 11 is cutting, the disturbance component 32 rotates and rubs within the slag recovery channel 31, which helps to cause the debris in the slag recovery channel 31 to fall off, thus reducing the situation where debris sticks to the inner wall of the slag recovery channel 31 and causes blockage, affecting the slag removal effect.

[0028] like Figure 3 and Figure 4 As shown, the disturbance component 32 includes a disturbance rod 321, one end of which is provided with a cleaning rod 322 that movably abuts against the filter sheet, and the outer wall of the cleaning rod 322 movably abuts against one side of the filter sheet; The outer wall of the disturbance rod 321 is provided with multiple sets of protrusions 323 at equal intervals. The height of the protrusions 323 increases from the end near the rotating channel 30 to the end near the negative pressure pipe 40. When the disturbance rod 321 rotates, it drives the protrusions 323 to squeeze the inner wall of the slag recovery channel 31, causing one end of the slag recovery channel 31 to expand into a trumpet-shaped structure. A brush is provided on the side of the cleaning rod 322 that contacts the filter plate.

[0029] The friction between the agitator rod 321 and the inner wall of the slag recovery channel 31 is increased, causing the debris to fall off. The cleaning rod 322 rubs one side of the filter plate, reducing the problem of blockage on one side of the filter plate affecting the negative pressure slag removal effect.

[0030] Meanwhile, the progressively increasing protrusions 323 help guide the direction of the debris, facilitate the transfer of the debris, and make it easier to recycle and process the debris.

[0031] like Figure 2 As shown, the material slag recovery channel 31 is provided with a conveying pipe 33 connected to the slag recovery pool 34 at one end near the negative pressure fan 50, and a recovery port is opened at the connection position between the material slag recovery channel 31 and the conveying pipe 33.

[0032] The debris in the slag recycling channel 31 moves through the recycling port to the conveying pipeline 33, and finally enters the slag recycling pool 34 for recycling, which is conducive to the recycling and utilization of gypsum debris and reduces waste.

[0033] like Figure 2 and Figure 5 As shown, the outer wall of the rotary cutting mechanism 10 is provided with a frame 13, and the frame 13 is provided with an annular slide rail 14 with the rotary cutting mechanism 10 as the center. A main bearing 141 is provided at one end of the rotary cutting mechanism 10. A secondary bearing 142 is provided on the outer wall of the rotating channel 30 and the inner wall of the annular slide rail 14. The main bearing 141 is slidably connected to the annular slide rail 14 through the secondary bearing 142.

[0034] The rotary cutting mechanism 10 rotates and cuts within the frame 13, simultaneously driving the collection cover 20 to move in a circle around the rotary cutting mechanism 10. The annular slide rail 14 provides rotation space for the collection cover 20, and the auxiliary bearing 142 rotatably connects the annular slide rail 14 and the main bearing 141, which helps maintain the stability of the rotary cutting mechanism 10 rotating inside the frame 13. This allows the rotary cutting mechanism 10 to drive the collection cover 20 to rotate synchronously, which in turn helps to further drive the disturbance component 32 to rotate, thus improving efficiency.

[0035] like Figure 2 and Figure 6 As shown, the collection cover 20 has a semi-enclosed structure on the outer wall of the cutter 11, and the bottom end of the collection cover 20 is in movable contact with the plasterboard. An extended nozzle 21 is movably provided at the bottom end of the collection cover 20. A spring is provided at the contact position between the extended nozzle 21 and the collection cover 20 to form an elastic telescopic structure. An anti-wear pad 211 is provided on the lower surface of the extended nozzle 21.

[0036] By semi-enclosing the outer wall of the cutter 11 with the collection cover 20, it is easier to control the range of debris during cutting and prevent debris from splashing. At the same time, the bottom of the collection cover 20 can elastically abut against the plate surface to form a relatively closed space, thereby creating a negative pressure environment to facilitate the removal of debris generated during cutting.

[0037] Meanwhile, the collection cover 20 facilitates the elastic contact between the cutter 11 and the board surface, and the anti-wear pad 211 reduces damage to the board surface, which helps to maintain a relatively closed state while following the cutting of the cutter 11, thereby ensuring the negative pressure slag removal effect.

[0038] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
