Description

Technical Field

[0001] The invention belongs to the technical field of plastic product processing, in particular to an automatic annular edge trimming device for plastic products. Background Art

[0002] Plastic products are a general term for daily and industrial products made from plastic as the main raw material, including products made from all processes such as injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials that are indispensable in daily life.

[0003] After cutting the thickened plastic pipe, the existing electric pipe cutting machine needs to use sandpaper to polish the cut edge and perform chamfering to reduce burrs on the edge. However, when the pipe body is being polished, the pipe body is prone to vibrate due to friction, and the fixed position and the cutting position may deviate, which may lead to uneven cuts or excessive polishing resulting in the pipe body being shortened and not meeting the standards. Therefore, improvements are needed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: an automatic circular edge trimming device for plastic products, comprising: Fixed base, set on the ground, made of heavy board; Long plastic tube, the part that needs to be cut is at the right end, such as Figure 1 As shown, the right end of the long plastic tube is cut; The main body component is arranged on the upper portion of the outer surface of the fixed base plate and is used to move the relevant cutting equipment; The docking component is combined with the main component to form a chuck to fix the tube body; The main body component includes: A fixed main plate, wherein the right side of the outer surface of the fixed main plate is fixedly connected with a splicing guide rail; A fixed ring sleeve, the outer surface of which is fixedly connected to the back of the outer surface of the fixed main plate; A movable inner plate, wherein the outer surface of the fixed ring sleeve is fixedly connected to the outer surface of the movable inner plate; A scale guide box, wherein the outer surface of the movable inner plate is slidably connected to the inner wall of the scale guide box, and tractors are symmetrically provided on both sides of the outer surface of the scale guide box, and the inner cavity of the tractor is connected to the side of the movable inner plate through a traction rope; The docking component includes: Docking plate shell, the docking plate shell has the same structure as the fixed main plate. After the docking plate shell and the fixed main plate are docked and merged, the long plastic tube can be clamped at the axis position, and a docking guide rail is installed on the right side of the outer surface of the docking plate shell. After the splicing guide rail of the fixed main plate and the docking guide rail of the docking plate shell are docked, Figure 1 As shown, a completed guide rail can be formed; The middle portion of the outer surface of the traction rotating rod is fixedly connected to the back of the outer surface of the docking disk shell, and the outer surface of the traction rotating rod is rotatably connected to the inner wall of the fixed ring sleeve.

[0005] Furthermore, it also includes: Composite tool for cutting and grinding long plastic pipes; The clamping component is arranged on the left side of the fixed base plate and is used for clamping the center of gravity of the long plastic tube.

[0006] Furthermore, the composite tool comprises: A matching riser, wherein the bottom of the outer surface of the matching riser is slidably connected to the inner wall of the splicing guide rail, and a reserved groove is opened on the side of the matching riser close to the long plastic tube; The saw blade is rotated, and the axis center of the inner wall of the saw blade is rotatably connected to the front end of the inner cavity of the matching vertical plate through the rotating shaft. Since the saw blade is inside the matching vertical plate, after the saw blade cuts the long plastic tube, the cross section of the long plastic tube will not fit perfectly with the side of the matching vertical plate, but will be squeezed against the side of the matching vertical plate and slightly deformed. Therefore, a reserved groove is provided on the matching vertical plate to compensate for the reserved length of the long plastic tube, so that the cross section of the long plastic tube can fit perfectly with the inner wall of the reserved groove; A rotating grinding rod, wherein the outer surface of the rotating grinding rod is rotatably connected to the inner cavity of the mating vertical plate, and one side of the grinding surface of the rotating grinding rod extends to the outside of the reserved groove. The side of the outer surface of the rotating grinding rod away from the reserved groove is rotatably connected to the outer surface of the mating vertical plate via a control wheel. The mating vertical plate drives the rotating grinding rod to rotate along its axis via the control wheel on the right side. The left side of the rotating grinding rod is a rough grinding surface, which grinds the contacted object when rotating at high speed, and the area of the grinding surface is larger than the cross-section of the long plastic pipe. There are two adsorption sleeves, and one side of the air inlet of the adsorption sleeve extends to the outside of the reserved groove.

[0007] Furthermore, the main body component also includes: A control motor, wherein the outer surface of the output shaft of the control motor is plugged into the axis center of the inner cavity of the traction rotating rod, and the outer surface of the control motor is fixedly connected to the outer surface of the movable inner plate through a fixed shell; A bottom connecting plate, the top end of which is fixedly connected to the outer surface of the fixed ring sleeve, and the bottom of the inner cavity of the bottom connecting plate is slidably connected to a traction connecting rod; A bending connecting plate, the back of which is fixedly connected to the front end of the traction connecting rod, and the top of which is fixedly connected to the front face of the matching vertical plate through a push plate.

[0008] Furthermore, the docking tray housing includes: A cross-sectional shell, wherein a matching circular groove is provided at the axis of the cross-sectional shell, and the outer surface of the long plastic tube fits perfectly with the inner wall of the matching circular groove; The filling arc plate has an inner cavity evenly provided with pressure-sensitive sliding balls. When the pressure-sensitive sliding balls contact the outer surface of the long plastic tube, they will be squeezed and contracted toward the inside of the cross-sectional shell. The outer surface of the filling arc plate is fixedly connected to the inner cavity of the cross-sectional shell through an adapting circular groove.

[0009] Furthermore, the docking tray housing further comprises: The conductive inner box has a front end fixedly connected to a pressure-sensitive pad, the outer surface of the pressure-sensitive sliding ball is fixedly connected to the inner cavity of the pressure-sensitive pad through a connecting spring, the rear end of the conductive inner box is fixedly connected to a display panel, and the display panel is located outside the cross-sectional shell, and the outer surface of the pressure-sensitive sliding ball and the outer surface of the long plastic tube are squeezed against each other.

[0010] Furthermore, the clamping component includes: A supporting slide plate, wherein the bottom of the outer surface of the supporting slide plate is slidably connected to the inner cavity of the fixed base plate through a slot; The bottom push rod box has an outer surface fixedly connected to the right side of the outer surface of the fixed bottom plate, and an inner cavity of the bottom push rod box is plugged into the bottom of the inner cavity of the supporting slide plate through a push rod.

[0011] Furthermore, the clamping component further includes: The outer ring shell has a middle portion of its outer surface plugged into the top of the inner cavity of the support slide, and friction balls are rollingly connected on both sides of the inner cavity of the outer ring shell. The opening diameter at the axis of the outer ring shell is larger than the outer diameter of the long plastic tube, so it needs to be changed to maintain the ability to clamp a tube with a smaller outer diameter; An internal rotating ring, the outer surface of which is rotatably connected to the axis of the inner cavity of the outer ring shell; A pressurized inner ring, the outer surface of which is fixedly connected to the inner wall of the built-in rotating ring, and segmented push rods are symmetrically arranged on both sides of the inner cavity of the pressurized inner ring. The pressurized inner ring can pressurize the segmented push rods on both sides, causing the distal rod bodies of the segmented push rods to slide and achieve a traction effect; The outer surface of the arc-shaped pad is fixedly connected to the end of the segmented push rod away from the pressurized inner ring, and the outer surface of the arc-shaped pad and the outer surface of the long plastic tube are pressed against each other.

[0012] The beneficial effects of the present invention are as follows: 1. The device can perform circular cutting on long plastic pipes. Since the composite tool has the functions of circular cutting and grinding the cutting surface at the same time, there is no need to remove the cut pipe body for separate grinding, thereby ensuring that the cutting point and the grinding point are always the same for calibration. In the process of grinding, since the cross-sectional end of the pipe body is located inside the reserved cutting groove, the plastic chips ground by the rotating grinding rod are easily concentrated inside the reserved cutting groove. The adsorption sleeves on both sides can recover the debris flying around the rotating grinding rod while ensuring that the debris does not spread to the outside, thereby making the workbench tidier and avoiding the problem of debris entering the relevant rotating joints and causing the device to jam.

[0013] 2. After the fixed main disk and the docking disk shell are combined, it can not only fix the end of the long plastic pipe, but also form a guide rail so that the matching vertical plate can slide stably and straight, ensuring the high flatness of the cutting plane. The rotating saw blade is always located inside the guide rail for cutting, so the rotating saw blade will not hurt people. The rear end of the inner wall of the guide rail is an arc-shaped buffer surface. After the high-speed rotating saw blade cuts the plastic pipe, it may continue to slide for a distance due to the propulsion effect. At this time, the inner wall of the guide rail can prevent the rotating saw blade from contacting related components such as the scale guide box, avoiding the problem of tool cutting device components causing damage to the tool and the device at the same time.

[0014] 3. The fixed main disk and docking disk shell of the device have been modified, and a conductive inner box is set inside. If the long plastic tube is thin and cannot adapt to the clamping effect of the docking parts, or the saw surface of the rotating saw blade is blunt, the long plastic tube cannot be cut smoothly. The pressure sensitivity displayed by the conductive inner box is large, and the cutting work needs to be stopped in time. The circular cutting work can only be carried out after the problem is eliminated to avoid the problem of uneven cross-section of the processed long plastic tube and easy processing of defective pipe fittings.

[0015] 4. During the ring cutting and grinding work, the friction balls on both sides of the outer ring shell will drive the built-in rotating ring to rotate through rolling friction. At this time, the arc pad that clamps the long plastic tube will also rotate synchronously, thereby changing the cutting point of the long plastic tube and the rotating saw blade, so that the cut line of the cross section of the long plastic tube will not shift to the side away from the rotating saw blade, avoiding the problem of serious deformation of the long plastic tube due to shear stress.

DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0019] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: an automatic circular trimming device for plastic products, comprising: The fixed base plate 1 is set on the ground and is made of thick and heavy plates; The long plastic tube 4, the part that needs to be cut is located at the right end, such as Figure 1 As shown, the right end of the long plastic tube 4 is cut; The main body part 2 is arranged on the upper part of the outer surface of the fixed base plate 1 and is used to move related cutting equipment; The docking component 3 is combined with the main component 2 to form a chuck for fixing the pipe body; The main body part 2 includes: A fixed main plate 26, the right side of the outer surface of which is fixedly connected with a splicing guide rail 27; A fixed ring sleeve 25, the outer surface of which is fixedly connected to the back of the outer surface of the fixed main plate 26; The outer surface of the movable inner plate 22 and the fixed ring sleeve 25 are fixedly connected to the outer surface of the movable inner plate 22; The outer surface of the scale guide box 21 and the movable inner plate 22 are slidably connected to the inner wall of the scale guide box 21. The tractors 23 are symmetrically provided on both sides of the outer surface of the scale guide box 21. The inner cavity of the tractor 23 is connected to the side of the movable inner plate 22 through a traction rope. The docking component 3 includes: The docking shell 31 has the same structure as the fixed main plate 26. After the docking shell 31 and the fixed main plate 26 are docked and merged, the long plastic tube 4 can be clamped at the axis position, and a docking guide rail 32 is installed on the right side of the outer surface of the docking shell 31. After the splicing guide rail 27 of the fixed main plate 26 and the docking guide rail 32 of the docking shell 31 are docked, Figure 1 As shown, a completed guide rail can be formed; The traction rotating rod 33 has a middle portion of an outer surface thereof fixedly connected to the back portion of the outer surface of the docking plate housing 31 , and an outer surface of the traction rotating rod 33 is rotatably connected to the inner wall of the fixed ring sleeve 25 .

[0020] Also includes: The composite cutter 5 is used for cutting and grinding the long plastic tube 4; The clamping component 6 is arranged on the left side of the fixed base plate 1 and is used to clamp the center of gravity of the long plastic tube 4.

[0021] The composite tool 5 comprises: The bottom of the outer surface of the matching riser 51 is slidably connected to the inner wall of the splicing guide rail 27, and a reserved groove 53 is opened on the side of the matching riser 51 close to the long plastic tube 4; The saw blade 52 is rotated, and the axis of the inner wall of the saw blade 52 is rotatably connected to the front end of the inner cavity of the mating vertical plate 51 through the rotating shaft. Since the saw blade 52 is inside the mating vertical plate 51, after the saw blade 52 cuts the long plastic tube 4, the cross section of the long plastic tube 4 will not fit perfectly with the side of the mating vertical plate 51, but will be squeezed by the side of the mating vertical plate 51 and slightly deformed. Therefore, a reserved groove 53 is opened on the mating vertical plate 51 to compensate for the reserved length of the long plastic tube 4, so that the cross section of the long plastic tube 4 can fit perfectly with the inner wall of the reserved groove 53; The grinding rod 54 is rotated, and the outer surface of the grinding rod 54 is rotatably connected to the inner cavity of the mating riser 51. One side of the grinding surface of the grinding rod 54 extends to the outside of the reserved groove 53. The side of the outer surface of the grinding rod 54 away from the reserved groove 53 is rotatably connected to the outer surface of the mating riser 51 via a control wheel. The mating riser 51 drives the grinding rod 54 to rotate around its axis via the control wheel on the right side. The left side of the grinding rod 54 is a rough grinding surface. When rotating at high speed, it will grind the contacted object, and the area of the grinding surface is larger than the cross-section of the long plastic tube 4. There are two adsorption sleeves 55 , and one side of the air inlet of the adsorption sleeve 55 extends to the outside of the reserved groove 53 .

[0022] The main body part 2 also includes: The control motor 24 has an outer surface of an output shaft of the control motor 24 plugged into the axis of the inner cavity of the traction rotating rod 33, and the outer surface of the control motor 24 is fixedly connected to the outer surface of the movable inner plate 22 through a fixed shell; A bottom connecting plate 28, the top of which is fixedly connected to the outer surface of the fixing ring 25, and a traction connecting rod 29 is slidably connected to the bottom of the inner cavity of the bottom connecting plate 28; The bent connecting plate 210 has its back fixedly connected to the front end of the traction link 29 , and its top end fixedly connected to the front face of the mating vertical plate 51 via a push plate.

[0023] Before using the device to cut the long plastic tube 4, control the motor 24 to rotate the traction rod 33 to deflect the docking disk shell 31 upward, thereby opening the slot at the axis of the disk shell, insert the left end of the long plastic tube 4 into the clamping component 6, adjust the position of the center of gravity so that the right side of the long plastic tube 4 is clamped in the slot of the fixed main disk 26, and then control the motor 24 to rotate the docking disk shell 31 in the opposite direction so that the docking disk shell 31 docks with the fixed main disk 26, and the right side of the long plastic tube 4 is clamped at the axis of the main disk.

[0024] After the long plastic tube 4 is clamped, the cutting point of the composite tool 5 is adjusted. The tractors 23 on both sides pull the movable inner plate 22 to slide along the scale guide box 21 through the internal traction rope. According to the scale data of the scale guide box 21, the sliding effect of the movable inner plate 22 is accurately controlled. Since the left side of the long plastic tube 4 is fixed by the clamping component 6, the disc slides relative to the outer surface of the long plastic tube 4 at this time, and the composite tool 5 also slides synchronously under the traction of the bottom connecting plate 28, thereby changing the cutting point.

[0025] When the composite cutter 5 performs the circular cutting work, since the splicing guide rail 27 and the docking guide rail 32 have been combined to form a complete slide rail, the upper and lower sides of the matching vertical plate 51 are both located inside the slide rail, and the bottom connecting plate 28 pulls the bent connecting plate 210 toward the side close to the long plastic tube 4 through the traction connecting rod 29. At this time, the matching vertical plate 51 slides along the inner wall of the slide rail toward the side close to the long plastic tube 4, and the matching vertical plate 51 drives the rotating saw blade 52 to rotate at high speed through the internal motor, thereby circularly cutting off the right end of the long plastic tube 4, and then continuing to cut the matching vertical plate 51. The plate 51 is pushed toward the side close to the scale guide box 21. At this time, the cross-section of the right end of the long plastic tube 4 will face the rotating grinding rod 54 inside the reserved groove 53. Then the rotating grinding rod 54 rotates at high speed under the action of the outer wheel of the vertical plate 51, and the cross-section of the right end of the long plastic tube 4 is flattened and chamfered through the grinding surface. Since the right end of the long plastic tube 4 is located inside the reserved groove 53, the plastic chips ground by the rotating grinding rod 54 are easily concentrated inside the reserved groove 53. At this time, the adsorption sleeves 55 on both sides absorb the debris flying around the rotating grinding rod 54.

[0026] After the long plastic tube 4 is processed, the matching vertical plate 51 is pulled back to its original position, the docking plate shell 31 is opened, the clamping component 6 releases the clamping force on the long plastic tube 4, the long plastic tube 4 is pulled out, and the next long plastic tube 4 is replaced to realize continuous processing.

[0027] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: Based on embodiment 1, the docking tray housing 31 includes: The cross-section shell 311 has an adapting circular groove at its axis, and the outer surface of the long plastic tube 4 fits perfectly with the inner wall of the adapting circular groove; The filling arc plate 312 has its inner cavity evenly provided with pressure-sensitive sliding balls 313. When the pressure-sensitive sliding balls 313 come into contact with the outer surface of the long plastic tube 4, they will be squeezed and contracted toward the inside of the cross-sectional shell 311. The outer surface of the filling arc plate 312 is fixedly connected to the inner cavity of the cross-sectional shell 311 through an adapting circular groove.

[0028] The docking housing 31 further comprises: The conductive inner box 315 has a front end fixedly connected to a pressure-sensitive pad 314, and the outer surface of the pressure-sensitive sliding ball 313 is fixedly connected to the inner cavity of the pressure-sensitive pad 314 through a connecting spring. The rear end of the conductive inner box 315 is fixedly connected to a display panel, and the display panel is located outside the cross-sectional shell 311. The outer surface of the pressure-sensitive sliding ball 313 and the outer surface of the long plastic tube 4 are squeezed against each other.

[0029] The clamping member 6 comprises: A supporting slide 61, wherein the bottom of the outer surface of the supporting slide 61 is slidably connected to the inner cavity of the fixed base plate 1 through a slot; The bottom push rod box 62 has an outer surface fixedly connected to the right side of the outer surface of the fixed bottom plate 1, and an inner cavity of the bottom push rod box 62 is plugged into the bottom of the inner cavity of the supporting slide 61 through a push rod.

[0030] The clamping member 6 further comprises: The outer ring shell 63 has the middle of its outer surface plugged into the top of the inner cavity of the support slide 61, and friction balls 64 are rollingly connected on both sides of the inner cavity of the outer ring shell 63. The opening diameter at the axis of the outer ring shell 63 is larger than the outer diameter of the long plastic tube 4, so it needs to be changed to maintain the ability to clamp a tube with a smaller outer diameter; An internal rotating ring 65, the outer surface of which is rotatably connected to the axis of the inner cavity of the outer ring shell 63; The pressurized inner ring 66 has an outer surface fixedly connected to the inner wall of the built-in swivel 65, and segmented push rods 67 are symmetrically provided on both sides of the inner cavity of the pressurized inner ring 66. The pressurized inner ring 66 can pressurize the segmented push rods 67 on both sides, causing the distal ends of the segmented push rods 67 to slide and achieve a traction effect; The outer surface of the arc-shaped pad 68 is fixedly connected to the end of the segmented push rod 67 away from the pressurized inner ring 66, and the outer surface of the arc-shaped pad 68 and the outer surface of the long plastic tube 4 are pressed against each other.

[0031] After the cross-section shell 311 is connected to the outer surface of the long plastic tube 4 through the notch at the axis, the outer surface of the long plastic tube 4 will fit the inner wall of the arc plate 312 and the axis of the cross-section shell 311. At this time, the pressure-sensitive sliding balls 313 on both sides will apply pressure to the pressure-sensitive pad 314 through the pressing spring. Under normal circumstances, the pressure applied by the long plastic tube 4 to the pressure-sensitive sliding balls 313 is constant. However, when the ring cutting work is performed, the clamped side of the long plastic tube 4 is closer to the cross section, and when the long plastic tube 4 is ring cut, the closer it is to the rotating saw blade 52, the greater the vibration force it receives. Therefore, the clamped part of the cross-section shell 311 will be subjected to a strong vibration force. At this time, the long plastic tube 4 will be squeezed and deformed at the axis of the cross-section shell 311 due to the vibration. Since the deformation amplitude is small, Therefore, the conductive inner box 315 and other related pressure-sensing components are used to amplify the amplitude of the long plastic tube 4, and the stability of the end of the long plastic tube 4 during cutting is displayed in the form of an external screen. If the rotating saw blade 52 is relatively sharp and the long plastic tube 4 is stably placed, the pressure-sensing amplitude displayed by the conductive inner box 315 is smaller. At this time, the cutting state of the long plastic tube 4 is relatively stable, which is an ideal working condition; if the long plastic tube 4 is thinner and cannot adapt to the clamping effect of the matching component 3, or the saw surface of the rotating saw blade 52 is blunt, the long plastic tube 4 cannot be cut smoothly, and the pressure-sensing amplitude displayed by the conductive inner box 315 is larger. It is necessary to stop the cutting work in time and eliminate the problem before performing the ring cutting work. Otherwise, the cut cross-section of the long plastic tube 4 cannot remain smooth, and it is easy to process defective pipe fittings.

[0032] When the clamping component 6 clamps the long plastic tube 4, the long plastic tube 4 is inserted into the axis of the outer ring shell 63, and then the inner ring 66 is pressurized to pressurize the segmented push rods 67 on both sides, so that the arc-shaped pads 68 on both sides clamp the outer surface of the long plastic tube 4. When performing ring cutting and grinding work, the friction balls 64 on both sides of the outer ring shell 63 will drive the built-in rotating ring 65 to rotate through rolling friction. At this time, the arc-shaped pads 68 that clamp the long plastic tube 4 will also rotate synchronously, thereby changing the cutting point of the long plastic tube 4 and the rotating saw blade 52, so that the cut line of the cross section of the long plastic tube 4 will not deviate to the side away from the rotating saw blade 52, thereby avoiding the problem of serious deformation of the long plastic tube 4 due to shear stress.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
