Description

Technical Field

[0001] The invention relates to the technical field of plastic barrel processing, in particular to a plastic barrel mouth deburring structure. Background Art

[0002] In the production process of plastic barrels, blow molding is one of the common manufacturing methods. However, this process often produces excess plastic material on the edge of the barrel mouth, the so-called "flash". These flash are the waste materials generated during the processing of plastic barrels. After the plastic barrel is formed, it needs to be removed to ensure the integrity of the plastic barrel and facilitate use with the barrel cover.

[0003] The traditional method of removing flash is to directly cut off the flash tail with a cutting machine or an angle grinder. However, this treatment method will produce a large number of burrs at the cutting position, and the barrel mouth cutting position needs to be trimmed to remove the burrs. Therefore, this processing method will make the plastic barrel processing more complicated, with more steps, resulting in a lot of waste of time and manpower. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a plastic barrel mouth deburring structure, and the specific technical solution adopted is:

[0013] A moving seat is slidably arranged on the inner side wall of the moving column, the second motor is fixed on the moving seat, a first cylinder is arranged on the moving seat, and a fixed end of the first cylinder is mounted on the inner side wall of the moving column;

[0014] Among them, the length direction of the slot plate is parallel to the moving direction of the moving seat.

Compared with traditional cutting machines or angle grinders, this method reduces the direct impact on the mouth of the barrel and realizes the simultaneous cutting and trimming, thereby reducing processing steps and improving efficiency. Since the arc-shaped cutter uses two sliding cutting methods to remove flash instead of the traditional straight cutting method, the generation of burrs and debris can be significantly reduced. The sliding cutting method makes the contact between the cutting edge and the plastic surface smoother, reducing material tearing and fragmentation caused by severe friction.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are 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 referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figures 1 to 7 As shown, a plastic barrel mouth deburring structure of the present invention comprises a support barrel 2 with an opening downward, a slide seat 3 is arranged at the bottom opening position of the support barrel 2, the slide seat 3 performs circular motion along the opening track of the support barrel 2, a moving column 4 is inserted and slidably inserted along the radial direction of the support barrel 2 on the slide seat 3, and an arc-shaped cutter 5 is arranged at the end of the moving column 4 facing the axis of the support barrel 2, and the arc-shaped cutter 5 is used to remove the flash at the barrel mouth position of the plastic barrel 1;

[0035] Among them, the shape of the arc cutter 5 is arc-shaped, and the end and side of the arc cutter 5 are provided with cutting edges. The opening of the arc cutter 5 faces the axis of the supporting barrel 2. When the arc cutter 5 is close to the plastic barrel 1, the cutting edge at the end of the arc cutter 5 reciprocates along the axis direction of the arc cutter 5 and cuts the burrs on the plastic barrel 1, realizing horizontal sliding cutting of the burrs. When the end of the arc cutter 5 cuts into the plastic barrel 1, the arc cutter 5 reciprocates along its own arc trajectory, and the arc cutter 5 performs a circular motion around the plastic barrel 1, realizing circular sliding cutting of the burrs.

[0036] In detail, the support barrel 2 is buckled outside the plastic barrel 1, and the axis of the support barrel 2 is in line with the axis of the barrel mouth of the plastic barrel 1. The slide 3 can move along the opening trajectory of the bottom of the support barrel 2, so that the slide 3 can perform a circular motion. At this time, the slide 3 will carry the moving column 4 and the arc cutter 5 to perform a circular motion synchronously. The support barrel 2 mainly provides support for its upper structure. The shape of the arc cutter 5 is arc-shaped, and the distance between the upper end of the arc cutter 5 and the axis of the support barrel 2 is smaller than the distance between the lower end of the arc cutter 5 and the axis of the support barrel 2. In this way, the upper end of the arc cutter 5 is closer to the outer wall of the barrel mouth of the plastic barrel 1, and the cutting edge at the end of the arc cutter 5 is used to cut into the barrel mouth of the plastic barrel 1. The arc cutter The cutting edge on the side of the arc cutter 5 is used to make a circular motion around the plastic barrel 1 after the end of the arc cutter 5 cuts into the mouth of the plastic barrel 1. At this time, the side cutting edge of the arc cutter 5 realizes the circumferential removal of the flash at the mouth of the plastic barrel 1. Since the shape of the arc cutter 5 is an arc, when the upper end of the arc cutter 5 cuts into the mouth of the plastic barrel 1 and uses the side cutting edge of the arc cutter 5 to perform circular removal, the arc opening of the arc cutter 5 faces downward. At this time, a convex arc surface can be formed at the mouth of the plastic barrel 1 after the removal, thereby directly achieving the trimming and cutting work at the mouth of the plastic barrel 1, that is, when the flash at the mouth of the plastic barrel 1 is removed, a synchronous trimming working mode is achieved to avoid burrs and debris residues.

[0037] When in use, the conveyor belt conveys the blow-molded plastic barrel 1 to the bottom of the support barrel 2, and the external pushing structure can push the support barrel 2 downward and buckle it outside the barrel mouth of the plastic barrel 1. At this time, the opening of the arc cutter 5 is horizontally facing the barrel mouth of the plastic barrel 1, and the movable column 4 slides on the slide seat 3 and moves the arc cutter 5 toward the barrel mouth of the plastic barrel 1. The arc cutter 5 reciprocates along the axis of the arc cutter 5 on the movable column 4. The upper end of the arc cutter 5 contacts the outer wall of the barrel mouth of the plastic barrel 1 and slides and cuts the barrel mouth of the plastic barrel 1 horizontally. When the end of the arc cutter 5 cuts into the barrel mouth of the plastic barrel 1, the arc cutter 5 stops It works by reciprocating along its own axis, so that the arc cutter 5 moves along its own arc trajectory, that is, the arc cutter 5 is continuously inserted into the barrel mouth of the plastic barrel 1. When the opening of the arc cutter 5 is downward, the arc cutter 5 stops inserting, and the arc cutter 5 reciprocates along the arc trajectory of the arc cutter 5 on the moving column 4, and controls the slide seat 3 to perform circular motion on the supporting barrel 2. At this time, the arc cutter 5 will perform circular motion at the opening position of the plastic barrel 1, and the arc cutter 5 uses the cutting edge of its side and the reciprocating motion of the arc cutter 5 to achieve circular sliding cutting of the barrel mouth position of the plastic barrel 1, thereby achieving the removal of the flash.

[0038] It should be pointed out here that since the arc cutter 5 uses a sliding cutting method to cut the flash of the mouth of the plastic barrel 1, the generation of burrs and debris can be effectively reduced. Combined with the special processing shape of the mouth of the plastic barrel 1 caused by the arc shape of the arc cutter 5 itself, the generation of burrs and debris can be further reduced.

[0039] Through the cutting edge design at the end and side of the arc-shaped cutter 5, combined with the reciprocating motion and circular motion of its arc-shaped trajectory, the flash at the mouth of the plastic barrel 1 can be efficiently removed, and the cut shape at the mouth of the barrel can be made into an outwardly convex arc. Compared with traditional cutting machines or angle grinders, this method reduces the direct impact on the mouth of the barrel and realizes the simultaneous cutting and trimming, thereby reducing the processing steps and improving efficiency. Since the arc-shaped cutter 5 uses two sliding cutting methods to remove flash instead of the traditional straight cutting method, the generation of burrs and debris can be significantly reduced. The sliding cutting method makes the contact between the cutting edge and the plastic surface smoother, reducing material tearing and fragmentation caused by severe friction.

[0040] Furthermore, the movable column 4 is provided with a through opening extending vertically and horizontally on one side of the axis of the supporting barrel 2, and the arc-shaped cutter 5 passes through the through opening, and a first slider 6 is slidably provided on the inner wall of the through opening, and the sliding direction of the first slider 6 is along the axis direction of the arc-shaped cutter 5, and the arc-shaped cutter 5 is slidably installed on the first slider 6 along its own shape trajectory;

[0041] The movable column 4 has a chamber inside, a first motor 10 is arranged on the inner wall of the chamber, a first rotating disk 7 is arranged at the output end of the first motor 10, the first rotating disk 7 is located in the through opening, a first shifting post 8 is eccentrically arranged on the end surface of the first rotating disk 7, an arcuate chute 9 is arranged on the outer wall of the arcuate cutter 5, the arcuate chute 9 is coaxial with the arcuate cutter 5, and the first shifting post 8 is slidably arranged in the arcuate chute 9;

[0042] The moving column 4 is provided with a power unit for providing power for the arc cutter 5 to slide on the first sliding block 6 .

[0043] In detail, the first motor 10 can push the arc cutter 5 to reciprocate along the axial direction of the arc cutter 5 through the first turntable 7, the first shifting column 8 and the arc chute 9. At this time, the arc cutter 5 performs reciprocating sliding cutting in the horizontal direction, and the arc cutter 5 drives the first slider 6 to slide on the inner wall of the opening. The power unit can drive the arc cutter 5 to perform an arc motion along its own trajectory, that is, the arc cutter 5 can slide on the first slider 6. At this time, the arc chute 9 on the arc cutter 5 moves relative to the first shifting column 8, and the first shifting column 8 and the arc chute 9 can maintain a mutual transmission state.

[0044] Furthermore, the power unit comprises a rotating column 11 rotatably mounted on the inner side wall of the through hole, a prism 12 is slidably inserted in the rotating column 11, a spur gear 13 is arranged at the end of the prism 12, a tooth groove 14 is opened on the outer wall of the arc-shaped cutter 5, and the spur gear 13 meshes with the teeth in the tooth groove 14;

[0045] The rotating column 11 is provided with a first bevel gear 15 , and the first bevel gear 15 is meshed with a second bevel gear 16 . A second motor 17 is provided inside the moving column 4 , and the second motor 17 is connected to the second bevel gear 16 via a transmission structure.

[0046] In detail, the axis of the spur gear 13 is parallel to the axis of the arc cutter 5. When the first shifting column 8 pushes the arc cutter 5 to move, the arc cutter 5 will use the inner wall of the tooth groove 14 on it to push the spur gear 13 to move. The spur gear 13 drives the prism 12 to slide on the rotating column 11. The rotating column 11 and the prism 12 maintain a transmission state. The second motor 17 can drive the second bevel gear 16 to rotate through the transmission structure. The second bevel gear 16 drives the spur gear 13 to rotate through the first bevel gear 15, the rotating column 11 and the prism 12, thereby driving the arc cutter 5 to slide on the first slider 6, and the second motor 17 can also drive the arc cutter 5 to perform an arc reciprocating motion along its own trajectory.

[0047] Furthermore, the transmission structure includes a second rotating disk 18 mounted on the output end of the second motor 17, a second shifting post 19 is eccentrically arranged on the second rotating disk 18, a slot plate 20 is sleeved on the outer side of the second shifting post 19, a transmission shaft 21 is arranged on the slot plate 20, and the transmission shaft 21 is transmission-connected to the second bevel gear 16;

[0048] A moving seat 23 is slidably disposed on the inner side wall of the moving column 4, the second motor 17 is fixed on the moving seat 23, a first cylinder 22 is disposed on the moving seat 23, and a fixed end of the first cylinder 22 is mounted on the inner side wall of the moving column 4;

[0049] Among them, the length direction of the slot plate 20 is parallel to the moving direction of the movable seat 23. When the second turntable 18 is coaxial with the transmission shaft 21, the second motor 17 drives the transmission shaft 21 to rotate. When the second turntable 18 is eccentrically located on one side of the transmission shaft 21, the second motor 17 drives the transmission shaft 21 to rotate reciprocatingly.

[0050] In detail, the first cylinder 22 can drive the second motor 17 to move through the moving seat 23, thereby adjusting the relative positions of the second turntable 18, the second shifting post 19 and the transmission shaft 21. When the second turntable 18 is coaxial with the transmission shaft 21, the second turntable 18 in a rotating state will drive the transmission shaft 21 to rotate through the second shifting post 19 and the slot plate 20. At this time, the second turntable 18 and the transmission shaft 21 rotate synchronously. When the first cylinder 22 contracts and drives the second turntable 18 to deviate from the axis of the transmission shaft 21, the second shifting post 19 moves to one side of the transmission shaft 21, and when the second turntable 18 rotates, the second shifting post 19 only moves on this side of the transmission shaft 21. In this way, the second shifting post 19 pushes the slot plate 20 to swing back and forth, the transmission shaft 21 rotates back and forth, and the arc cutter 5 slides back and forth on the first slider 6.

[0051] Based on the above structure, the relative position of the second shifting post 19 and the transmission shaft 21 can be adjusted to realize the double motion mode of the arc cutter 5 cutting into the mouth of the plastic barrel 1 and the arc cutter 5 reciprocating along its own trajectory.

[0052] Furthermore, a support column 24 is rotatably inserted in the middle position of the bottom of the support barrel 2, a cross bar 25 is fixed on the outer wall of the support column 24 inside the support barrel 2, an adjustment sleeve 26 is slidably sleeved on the cross bar 25, and the adjustment sleeve 26 is fixedly connected to the movable column 4 by a connecting rod 27.

[0053] In detail, when the support column 24 rotates, it will drive the movable column 4 and the slide 3 to perform circular motion through the cross bar 25, the adjustment sleeve 26 and the connecting rod 27. When the adjustment sleeve 26 slides on the cross bar 25, the adjustment sleeve 26 can push the movable column 4 to slide on the slide 3 through the connecting rod 27, thereby adjusting the position of the arc cutter 5.

[0054] It should be pointed out here that, since the circular motion radius of the arc-shaped cutter 5 can be adjusted, plastic barrels 1 of different calibers can be processed.

[0055] Furthermore, a support frame 28 is provided on the top of the support barrel 2, and a second cylinder 29 is vertically provided on the support frame 28. A connecting plate 30 is rotatably provided on the lower movable end of the second cylinder 29, and a plug plate 31 is provided at the bottom of the connecting plate 30. The bottom of the plug plate 31 slides through the support column 24 and extends into the support barrel 2. The plug plate 31 is rotatably connected to the connecting rod 27 through an adjusting arm 32.

[0056] In detail, the support frame 28 provides support for the second cylinder 29. When the second cylinder 29 performs telescopic movement, the second cylinder 29 will drive the connecting rod 27 to move through the connecting plate 30, the plug plate 31 and the adjusting arm 32, thereby adjusting the distance between the arc cutter 5 and the axis of the support barrel 2. Since the support column 24 needs to rotate, the connecting plate 30 needs to be rotatably connected to the output end of the second cylinder 29.

[0057] Furthermore, a third motor 33 is fixed on the top of the support barrel 2, a third bevel gear 34 is provided on the outer wall of the support column 24 on the upper side of the support barrel 2, a fourth bevel gear 35 is meshed on the third bevel gear 34, and the fourth bevel gear 35 is installed on the output end of the third motor 33.

[0058] In detail, the third motor 33 can drive the support column 24 to rotate through the third bevel gear 34 and the fourth bevel gear 35, thereby providing power for the circular motion of the arc cutter 5.

[0059] Furthermore, an annular guide rail 36 is provided on the inner wall of the support barrel 2 , and a second slider 37 is slidably provided on the annular guide rail 36 , and the second slider 37 is fixedly connected to the end of the cross bar 25 .

[0060] In detail, the cross bar 25 can drive the second slider 37 to slide on the annular guide rail 36, so that the annular guide rail 36 and the second slider 37 can achieve auxiliary support effect for the cross bar 25 and the connecting rod 27, thereby improving the stability of equipment operation.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
