Description

Technical Field

[0001] The invention belongs to the technical field of plastic plate processing, in particular to a soft plastic plate cutting device and process. Background Art

[0002] With the development of modern industry, plastic materials are widely used in various fields, such as construction, automobiles, home appliances, packaging, etc. Plastic sheets have become important engineering materials due to their good processability, light weight, strong corrosion resistance, etc. Plastic sheets usually need to be cut into sections during processing. When cutting, the rapid friction between the plastic and the cutting knife generates heat, which can easily cause the temperature of the plastic sheet to be too high and deform. In particular, some plastic sheets with softer materials are more likely to be overheated and produce uneven surfaces at the cut section, causing the quality of the plastic sheet to decline or even become scrapped.

[0003] A Chinese patent application CN221622334U discloses a plastic plate cutting device, the main points of its technical solution are: it includes a horizontal first supporting table and a second supporting table, there is a gap between the first supporting table and the second supporting table, a cutting disc is arranged in the gap, the cutting disc is connected to a rotating shaft, the rotating shaft is connected to a cutting drive mechanism, the cutting drive mechanism and the rotating shaft are mounted on a movable bracket, and the movable bracket is connected to a feed drive mechanism; a cooling trough is arranged below the gap, coolant is arranged in the cooling trough, the top of the cutting disc is above the first supporting table and the second supporting table, and the bottom of the cutting disc is located in the coolant; a pushing mechanism is arranged at one end of the first supporting table in accordance with the gap, and limiting mechanisms are arranged on both sides of the first supporting table.

[0004] However, the above technology often has the following defects: it immerses the bottom of the cutting knife in water, and then during the rotation of the cutting knife, the water can cool it down and avoid the cutting knife from being too hot, so as to prevent the cut of the plastic plate from being deformed due to heat. However, when the cutting knife of this technology rotates, its bottom will be hindered by the water, thereby increasing the rotation resistance of the cutting knife and reducing the cutting efficiency of the plastic plate. In addition, after the bottom of the cutting knife enters the water, a large amount of water remains on the surface of the cutting knife and is thrown outward with the centrifugal force of rotation, resulting in the problem of excessive residual water on the surface of the plastic plate, affecting the subsequent processing technology of the plastic plate.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 6 As shown, a soft plastic plate cutting device according to the present invention comprises a machine tool 1, a fixing seat 2 and a cutting assembly; a cutting groove 3 is provided on the surface of the machine tool 1;

[0039] The fixing seats 2 are provided with a pair and are distributed on both sides of the cutting groove 3; a screw rod 4 is rotatably connected between the fixing seats 2, and the screw rod 4 is driven by a motor 5;

[0040] The cutting assembly is used to move along the cutting groove 3 and cut the plastic plate 6; the cutting assembly includes a moving box 7; a coupling member 8 is fixedly connected to the bottom of the moving box 7; the screw rod 4 passes through the coupling member 8 and is connected to the coupling member 8 through a screw rod nut pair; a cutting knife 9 is rotatably connected to the top of the moving box 7, and the rotating shaft 10 of the cutting knife 9 is driven by a motor 11; the top of the cutting knife 9 protrudes from the upper side of the moving box 7 and is located inside the cutting groove 3;

[0041] A submersible pump 12 is fixedly connected to the bottom of the mobile box 7; a group of atomizing nozzles 13 are fixedly connected to the inner wall of the mobile box 7; a conduit 14 is connected between the atomizing nozzle 13 and the submersible pump 12; a porous cover 15 is arranged outside the atomizing nozzle 13, and the holes of the porous cover 15 and the atomizing nozzle 13 are staggered.

[0042] The plastic plate 6 cutting device in the prior art immerses the bottom of the cutting knife 9 in water, and then during the rotation of the cutting knife 9, the water can cool it down to avoid the cutting knife 9 from being too hot, so as to prevent the incision of the plastic plate 6 from being deformed by heat. However, when the cutting knife 9 of this technology rotates, its bottom will be hindered by water, thereby increasing the rotation resistance of the cutting knife 9 and reducing the cutting efficiency of the plastic plate 6. In addition, after the bottom of the cutting knife 9 enters the water, a large amount of water remains on the surface of the cutting knife 9 and is thrown outward with the centrifugal force of rotation, resulting in the problem of excessive residual water on the surface of the plastic plate 6, affecting the subsequent processing technology of the plastic plate 6.

[0043] The present invention adds cooling water to the inside of the moving box 7 before use, and makes the water level lower than the bottom of the cutting knife 9 and the atomizing nozzle 13. During cutting, the screw rod 4 is controlled to rotate by the motor 1 5 to drive the moving box 7 to move along the cutting groove 3. At the same time, the cutting knife 9 is driven to rotate by the motor 2 11, so that the cutting knife 9 moves inside the cutting groove 3 and cuts the plastic plate 6. In this process, the cooling water inside the moving box 7 is pumped into the atomizing nozzle 13 by the submersible pump 12 to spray mist water droplets. The atomizing nozzle 13 first hits the inner side of the porous cover 15 when spraying water to prevent the water droplets from directly contacting the cutting knife 9. After the water droplets hit and splash, their particle size can be reduced, and the fineness and generation efficiency of the water mist can be improved. Then the water mist escapes outward through the holes on the surface of the porous cover 15, so that a large amount of diffuse water mist can be formed in the top of the moving box 7, and then the water mist can be cooled after contacting the cutting knife 9 to prevent the soft plastic plate 6 from overheating and deformation during the cutting process.

[0044] The cutting knife 9 in the present invention does not come into direct contact with the cooling water during the rotation process, but is cooled by water mist, which can improve the cooling uniformity of the cutting knife 9, reduce the movement resistance of the cutting knife 9, and no large amount of water will remain on the surface of the cutting knife 9 and be thrown out by it. In addition, part of the water mist escapes outward through the top of the moving box 7, thereby capturing the plastic powder generated during the cutting process and reducing the degree of dust pollution to the working environment.

[0045] It is worth noting that in order to improve the cutting efficiency of the plastic plate 6, a pushing mechanism, a limiting mechanism, etc. are preferably set on the surface of the machine tool 1, which are all existing technologies. The detailed technical solution can be referred to CN221622334U, and will not be elaborated here.

[0046] As a preferred embodiment of the present invention, a dust shield shell 16 is fixedly connected to the upper side of the movable box 7, and the cutting knife 9 is located inside the dust shield shell 16, and the dust shield shell 16 is located inside the cutting groove 3; processing boxes 17 are fixedly connected on both sides of the movable box 7; a dust suction pipe 18 is connected between the processing box 17 and the dust shield shell 16; a filter screen 19 and absorbent cotton 20 are arranged in sequence from top to bottom inside the processing box 17; a negative pressure component is connected to the bottom of the processing box 17; the negative pressure component is used to suck the dust generated during the cutting process.

[0047] The negative pressure assembly includes a negative pressure cylinder 21, and the negative pressure cylinder 21 is connected to the bottom of the processing box 17; a spiral auger 22 is rotatably connected inside the negative pressure cylinder 21; one end of the rotating shaft 10 extending outside the moving box 7 is fixedly connected to a driving wheel 23; the end of the spiral auger 22 is fixedly connected to a driven wheel 24; the driving wheel 23 and the driven wheel 24 are connected through a belt 25.

[0048] During the cutting process, the dust shield 16 can move in the cutting groove 3, and a relatively closed space is formed between the dust shield 16 and the plastic plate 6, thereby blocking the generated plastic powder and reducing the powder from spreading into the surrounding air. When the rotating shaft 10 rotates, the driving wheel 23, the belt 25, and the driven wheel 24 drive the spiral auger 22 to rotate inside the negative pressure cylinder 21, and then the spiral auger 22 pushes the airflow and generates negative pressure, so that the air and water mist inside the dust shield 16 entrain the powder, and the powder is sucked into the processing box 17 through the dust suction pipe 18, and is processed by the filter screen 19 and the absorbent cotton 20 in turn. The filter screen 19 can filter the solid debris in the airflow, and the absorbent cotton 20 can absorb the water mist in the airflow.

[0049] As a preferred embodiment of the present invention, a storage chamber 26 is provided on the side of the processing box 17, and the top of the storage chamber 26 is connected to the processing box 17; the filter 19 is inclined toward the storage chamber 26; an opening is provided at the bottom of the storage chamber 26, and a slide 27 is slidably connected inside the opening. Solid debris intercepted by the surface of the filter 19 can automatically enter the storage chamber 26 along the inclined surface, thereby collecting impurities, maintaining the functionality of the filter 19, and reducing its clogging phenomenon. When the storage chamber 26 needs to be cleaned, the slide 27 can be pulled outward to open the opening at the bottom of the storage chamber 26, and the impurities will fall downward and be discharged.

[0050] As a preferred embodiment of the present invention, one end of the spiral auger 22 extending into the processing box 17 is fixedly connected to a wheel disc 28; a group of guide wheels 29 are evenly distributed at the edge of the wheel disc 28; an upper grid plate 30 and a lower grid plate 31 are fixedly connected on both sides of the absorbent cotton 20; the upper grid plate 30 is fixedly connected to the inside of the processing box 17, and the lower grid plate 31 is slidably connected to the inside of the processing box 17; a compression spring is fixedly connected between the upper grid plate 30 and the lower grid plate 31; a return pipe 32 is connected between the bottom of the processing box 17 and the movable box 7, and a one-way valve is arranged inside the return pipe 32. When the spiral auger 22 rotates, it drives the wheel disc 28 to rotate together. The guide wheel 29 on the surface of the wheel disc 28 intermittently rolls on the surface of the lower grid plate 31 and cooperates with the compression spring to cause the lower grid plate 31 to continuously reciprocate up and down, thereby squeezing out the moisture inside the absorbent cotton 20 to maintain a high water absorption efficiency. The squeezed water flows back into the mobile box 7 along the return pipe 32 to recycle the cooling water and reduce water resource consumption.

[0051] The upper side of the lower grid plate 31 is fixedly connected with a connecting rod 33; one end of the connecting rod 33 extending to the lower side of the filter screen 19 is fixedly connected with a pressing cap 34, and the connecting rod 33 penetrates the absorbent cotton 20 and the upper grid plate 30 and slides with them; the filter screen 19 is made of elastic material, such as nylon, rubber, etc. When the lower grid plate 31 moves upward, it can drive the pressing cap 34 to squeeze the filter screen 19 through the connecting rod 33, causing the filter screen 19 to creep and deform upward, thereby promoting the impurities on its surface to fall along its inclined surface to the storage chamber 26, and improving the separation efficiency between the impurities and the filter screen 19.

[0052] As a preferred embodiment of the present invention, the surface of the machine tool 1 is provided with grooves at both sides of the cutting groove 3; a filling sleeve 35 is fixedly connected inside the groove, and the top of the filling sleeve 35 is flush with the upper surface of the machine tool 1; and a coolant is provided inside the filling sleeve 35. By providing the filling sleeve 35, the plastic plate 6 can contact the filling sleeve 35 after being placed on the surface of the machine tool 1, and then during the cutting process, the coolant inside the filling sleeve 35 is used to exchange heat with the cutting seam of the plastic plate 6, further cooling the plastic plate 6 and preventing it from overheating and deformation, thereby improving the cutting quality of the plastic plate 6 and reducing the uneven cross-section phenomenon caused by cutting.

[0053] A magnetic plate 36 is fixedly connected to the inner wall of the top of the moving box 7; a group of follower blocks 37 are evenly distributed inside the filling sleeve 35; a tension spring 38 is fixedly connected between the follower block 37 and the top of the filling sleeve 35; a wave plate 39 is fixedly connected to the surface of the follower block 37; the magnetic plate 36 and the follower block 37 attract each other when they are close. As the moving box 7 gradually moves along the cutting groove 3, when the magnetic plate 36 reaches below the follower block 37, the follower block 37 is driven downward by the magnetic attraction, and the tension spring 38 is stretched to store energy, and when the magnetic plate 36 gradually moves away, the tension spring 38 drives the follower block 37 and the wave plate 39 to swing up and down inside the filling sleeve 35, which plays a role in disturbing the coolant, promoting the coolant between different positions to flow and exchange with each other, so that the heat is evenly distributed, thereby further improving the heat absorption efficiency of the coolant to the plastic plate 6.

[0054] like Figure 7 As shown, a soft plastic plate cutting process according to the present invention, which adopts the above-mentioned soft plastic plate cutting device, comprises the following steps:

[0055] S1: The screw 4 is controlled to rotate by the motor 1 5, driving the moving box 7 to move along the cutting groove 3, and the rotating shaft 10 and the cutting knife 9 are controlled to rotate by the motor 2 11 to cut the plastic plate 6;

[0056] S2: The water level inside the moving box 7 is lower than the bottom of the cutting blade 9 and the atomizing nozzle 13, and the cooling water is pumped into the atomizing nozzle 13 by the submersible pump 12, so that it sprays out mist-like water droplets;

[0057] S3: The mist water droplets hit the inner side of the porous cover 15 and splash around to disperse, and then the water mist escapes outward through the holes on the surface of the porous cover 15, forming a large amount of diffuse water mist on the top of the moving box 7, and the water mist contacts the cutting knife 9 and cools it down;

[0058] S4: When the rotating shaft 10 rotates, the driving wheel 23, the belt 25, and the driven wheel 24 drive the spiral auger 22 to rotate inside the negative pressure cylinder 21, and then the spiral auger 22 pushes the airflow and generates negative pressure, so that the air and water mist inside the dust shield 16 entrain the powder, and the powder is sucked into the processing box 17 through the dust suction pipe 18;

[0059] S5: The solid debris in the airflow is filtered through the filter 19, and the water mist in the airflow is absorbed by the absorbent cotton 20 to reduce the influence of the airflow discharged by the negative pressure cylinder 21 on the air.

[0060] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0061] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
