DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 11, the present invention provides a technical solution: Embodiment 1, a sealing component cutting and processing device, comprises: a mounting plate 1 and a discharge cylinder 6 .

[0021] Specifically, a rubber tube workpiece 2 is arranged outside the front of the mounting plate 1, and a support tube 3 is movably inserted into the inner cavity of one end of the rubber tube workpiece 2, and the inner diameter of the support tube 3 is smaller than the diameter of the rubber tube workpiece 2. Figure 2 As shown, the support tube 3 is eccentric to the rubber tube workpiece 2, the upper surface of the support tube 3 is fitted with the upper inner wall of the rubber tube workpiece 2, the support tube 3 is movably connected with the mounting plate 1, and the support tube 3 and the mounting plate 1 can both rotate relative to each other and move relative to each other. When the support tube 3 slides along its own length direction, it can be inserted into the inner cavity of the rubber tube workpiece 2 or separated from the rubber tube workpiece 2. A cutting assembly 4 driven by a clamping cylinder 7 to move up and down is arranged directly above the support tube 3, and the lower end of the cutting assembly 4 is just opposite to the fitting connection between the rubber tube workpiece 2 and the support tube 3. The cutting assembly 4 is mainly used for cutting the rubber tube workpiece 2, and clamping rollers 5 are arranged on both sides of the cutting assembly 4. A clamping frame 52 for positioning the clamping roller 5 is installed on the outer side of the clamping roller 5. The clamping frame 52 is fixedly connected to the movable end of the clamping cylinder 7 through a crossbeam. When the clamping cylinder 7 extends downward, the cutting assembly 4 and the clamping roller 5 move simultaneously. The clamping roller 5 presses down the rubber tube workpiece 2 from both sides of the joint between the rubber tube workpiece 2 and the support tube 3. The rubber tube workpiece 2 itself is flexible and can undergo elastic deformation. Therefore, the rubber tube workpiece 2 can be deformed and increase the fitting area between the support tube 3. When the clamping roller 5 presses the rubber tube workpiece 2, the cutting assembly 4 contacts the rubber tube workpiece 2. At this time, the support tube 3 rotates and drives the rubber tube workpiece 2 to rotate through friction, and the cutting assembly 4 can realize the cutting of the rubber tube workpiece 2. In addition, a plurality of annular grooves 51 are provided on the surface of the pressure roller 5 and are distributed at equal intervals along the axial direction thereof. When the pressure roller 5 presses the upper side of the rubber tube workpiece 2 against the surface of the support tube 3, the annular grooves 51 can limit the rubber tube workpiece 2 to prevent the rubber tube workpiece 2 from being displaced in its own axial direction. At the same time, the annular grooves 51 pre-press grooves on the surface of the rubber tube workpiece 2 to facilitate cutting by the cutting assembly 4. In addition, a plurality of friction patterns 32 are provided on the surface of the support tube 3 and are distributed in an annular array around its axis. The setting of the friction patterns 32 can increase the friction force between the support tube 3 and the rubber tube workpiece 2, and ensure that when the support tube 3 rotates, the support tube 3 can drive the rubber tube workpiece 2 to rotate through the friction force. Furthermore, the unloading cylinder 6 is fixedly mounted on the back of the mounting plate 1 through a stand 61. The unloading cylinder 6 is concentric with the support tube 3. The movable end of the unloading cylinder 6 is inserted into the inner cavity at one end of the support tube 3 and is rotatably connected to the support tube 3 through a bearing 62. The setting of the unloading cylinder 6 enables the support tube 3 to only rotate around its own axis without positional displacement in its own radial direction. A driving component for driving the support tube 3 to rotate is installed on the back of the mounting plate 1. When the driving component is working, it drives the support tube 3 to rotate, thereby driving the rubber tube workpiece 2 to rotate. When the unloading cylinder 6 is closed, the support tube 3 is rotated. When contracted, the unloading cylinder 6 can drive the support tube 3 to move along its own axial direction through the bearing 62 until the support tube 3 moves to the outside of the back side of the mounting plate 1, and the support tube 3 can be separated from the rubber tube workpiece 2. After the cutting assembly 4 completes the cutting of the rubber tube workpiece 2, the rubber ring obtained by cutting will be sleeved on the outside of the support tube 3. Therefore, the sealing ring can be separated from the support tube 3 by contracting the unloading cylinder 6, and the sealing ring can fall naturally under the action of gravity. After that, the unloading cylinder 6 extends to drive the support tube 3 to reinsert into the inner cavity of the rubber tube workpiece 2, and then the next cutting work can be carried out.

[0022] In order to describe the structure of the driving component in detail, the driving component of the present application includes a sliding cover shell 9, and a notch is opened on the side of the sliding cover shell 9, and the notch is opposite to the support cylinder 3. A driving gear 91 is rotatably installed in the inner cavity of the sliding cover shell 9, and an outer gear ring 31 is fixed to one end of the support cylinder 3 and the diameter of the outer gear ring 31 is larger than the diameter of the support cylinder 3. The outer gear ring 31 fits the back of the mounting plate 1 and the outer gear ring 31 is meshed with the driving gear 91 for transmission. The setting of the outer gear ring 31 is used on the one hand to limit the sliding of the support cylinder 3 to prevent the support cylinder 3 from being separated from the front of the mounting plate 1, and on the other hand, it is meshed with the driving gear 91 and can be driven to rotate by the driving gear 91. Since the outer gear ring 31 and the driving gear 91 are on the public surface, when the unloading cylinder 6 contracts, the support cylinder 3 and the outer gear ring 31 can move synchronously, and the outer gear ring 31 can be separated from the driving gear 91. In other words, the driving gear 91 will not hinder or interfere with the sliding of the support cylinder 3.

[0023] In order to prevent partial overlap between the driving gear 91 and the external gear ring 31, which may cause the driving gear 91 and the external gear ring 31 to be unable to mesh with each other, the present application further has a driving motor 93 fixed on the surface of the sliding housing 9 to drive the driving gear 91 to rotate. A guiding ring 92 is fixed at the edge of the side of the driving gear 91 away from the mounting plate 1. The outer sidewall of the guiding ring 92 is inclined. A fixing seat 94 is arranged outside the sliding housing 9. The fixing seat 94 is fixed to the back of the mounting plate 1. An elastic telescopic rod 95 is fixedly installed on the fixing seat 94. The length direction of the elastic telescopic rod 95 is consistent with the diameter direction of the external gear ring 31, and the movable end of the elastic telescopic rod 95 is fixedly connected to the sliding housing 9. The elastic telescopic rod 95 is internally provided with a spring, and the elastic telescopic rod 95 is always in an extended state, which can be used to press the driving gear 91 outside the external gear ring 31 to ensure that the two are always in a tightly fitting state. When the unloading cylinder 6 contracts to drive the external gear ring 31 to move and错开 from the driving gear 91, the driving gear 91 will move slightly towards the direction close to the support cylinder 3 under the action of the elastic telescopic rod 95. At this time, when the unloading cylinder 6 extends to drive the support cylinder 3 and the external gear ring 31 to reset, there will be a partially overlapping area between the external gear ring 31 and the driving gear 91. The setting of the guiding ring 92 can make the guiding ring 92 contact the external gear ring 31 before the driving gear 91. At this time, the external gear ring 31 contacts the guiding ring 92 and exerts extrusion on its outer sidewall, causing the driving gear 91 to move away from the support cylinder 3, and the elastic telescopic rod 95 can be compressed, thereby preventing partial overlap between the driving gear 91 and the external gear ring 31 from affecting the movement of the external gear ring 31 close to the mounting plate 1. When the external gear ring 31 moves to fit the back of the mounting plate 1, the external gear ring 31 can be re-meshed with the driving gear 91.

[0024] In order to cut and process the rubber tube workpiece 2, the cutting assembly 4 of the present application includes a mounting frame 41. The mounting frame 41 is in a "C" shape with an opening facing downwards. A scale shaft rod 42 and a guiding shaft rod 43 parallel to each other are fixed between the two ends of the mounting frame 41. A plurality of cutting knives 45 are arranged below the mounting frame 41 in an equally spaced linear distribution, and an adjusting plate 44 is fixed to the upper end of the cutting knife 45. Circular holes 442 are opened at both the upper and lower ends of the adjusting plate 44, and the scale shaft rod 42 and the guiding shaft rod 43 respectively pass through and are movably connected to the two circular holes 442. Figure 7 、 Figure 8 和 Fig. 9 As can be seen from the figures shown, the adjusting plate 44 can slide along the length directions of the scale shaft rod 42 and the guiding shaft rod 43, and the scale shaft rod 42 and the guiding shaft rod 43 cooperate to position the adjusting plate 44, so that the adjusting plate 44 can always be kept vertical and will not tilt or deflect. Therefore, the cutting knives 45 can always coincide with the radial direction of the support cylinder 3. When the support cylinder 3 rotates, the cutting knives 45 can cut the rubber tube workpiece 2, and a plurality of cutting knives 45 can simultaneously cut and form a plurality of sealing rings, thereby improving the cutting and processing efficiency.

[0025] In order to adjust the distance between two adjacent adjustment plates 44, the present application also has a magnet block 441 fixedly installed in the middle of the adjustment plate 44, and the magnet blocks 441 on the two adjacent adjustment plates 44 repel each other. Figure 8 and Fig. 9 As shown, two adjacent magnet blocks 441 repel each other, so that the two adjacent adjustment plates 44 always have a tendency to move away from each other, and because the models and performances of the multiple magnet blocks 441 are completely consistent, the spacing between the multiple adjustment plates 44 can be kept consistent. Since the spacing between two adjacent cutters 45 is small, the present device uses a non-contact magnet block 441 to control the spacing between the two adjacent adjustment plates 44. Compared with traditional springs or "X"-shaped frames and other structures, the occupied volume is smaller. A boss 412 is fixed to the inner wall of one end of the mounting frame 41, and the boss 412 is attached to an adjustment plate 44, such as Figure 8 As shown, the boss 412 abuts against the surface of the rightmost adjusting plate 44 to limit its position. An adjusting member 411 is connected to the other end of the mounting frame 41 through a thread. One end of the adjusting member 411 abuts against another adjusting plate 44. The staff can change the position of the leftmost adjusting plate 44 by adjusting the position of the adjusting member 411. With the repulsive force of the magnet block 441, the positions of multiple adjusting plates 44 other than the rightmost adjusting plate 44 can be changed synchronously. The spacing between adjacent multiple adjusting plates 44 is consistent. The adjusting member 411 can be as follows Figure 8 The screw rod and knob shown may also be existing known structures with telescopic functions such as air cylinders and oil cylinders.

[0026] In order to drive the cutter 45 to move downward, the present application also has a connecting horizontal plate 46 and a lower pressure plate 47 arranged in sequence from top to bottom above the scale shaft 42, and both ends of the connecting horizontal plate 46 and the lower pressure plate 47 are fixedly provided with guide protrusions 461, and the inner walls of both ends of the mounting frame 41 are provided with guide vertical grooves 413, and the guide protrusions 461 are slidably installed in the inner cavity of the guide vertical grooves 413 at the corresponding position and adapted thereto, combined with Figure 7 , Figure 8 and Fig.10As shown, the connecting cross plate 46 and the lower pressure plate 47 can only slide up and down along the vertical direction inside the mounting frame 41. A compression spring 48 is fixedly installed between the connecting cross plate 46 and the lower pressure plate 47. The compression spring 48 provides a thrust to push the connecting cross plate 46 and the lower pressure plate 47 away from each other, and the movable end of the compression cylinder 7 moves through the middle of the mounting frame 41 and is fixedly connected to the connecting cross plate 46. The compression cylinder 7 can limit the mounting frame 41 on the one hand to prevent the mounting frame 41 from tilting, and on the other hand, it can push the connecting cross plate 46 downward; when the cutting assembly 4 of the device is in the initial position, the mounting frame 41 will move downward under the action of gravity, so that the scale The shaft rod 42 and the guide shaft rod 43 will move away from the connecting cross plate 46. When the clamping cylinder 7 extends and drives the cutting assembly 4 to move downward as a whole, the cutter 45 first contacts the rubber tube workpiece 2 and is blocked by the support tube 3. At this time, the position of the mounting frame 41 is stable, and the clamping cylinder 7 continues to move downward and drives the connecting cross plate 46 and the lower pressure plate 47 to move downward until the lower pressure plate 47 is pressed on the upper end of the adjusting plate 44 to maintain a stable position, while the connecting cross plate 46 continues to move downward and increases the compression degree of the clamping spring 48. The thrust of the clamping spring 48 on the lower pressure plate 47 acts on the adjusting plate 44, thereby realizing the downward pressure of the cutter 45, so that the cutter 45 can cut the rubber tube workpiece 2.

[0027] In order to prevent the adjustment plate 44 from shifting in position, the present application also has guide posts 472 fixedly installed at both ends of the lower pressure plate 47, and the guide posts 472 movably penetrate the ends of the connecting cross plates 46, and the setting of the guide posts 472 is used to limit the distance between the connecting cross plates 46 and the lower pressure plate 47, and an anti-skid layer 471 is bonded to the lower surface of the lower pressure plate 47, and a plurality of tooth grooves 443 are linearly distributed at equal intervals along the length direction of the scale shaft 42 on the upper end surface of the adjustment plate 44, which are used to increase the contact friction between the lower pressure plate 47 and the adjustment plate 44. After being pressed, the two can remain relatively fixed, avoiding the position displacement of the adjustment plate 44 in the length direction of the scale shaft 42, thereby ensuring that the sizes of the multiple sealing rings obtained by the cutter 45 are more consistent, and when the clamping cylinder 7 contracts and drives the connecting cross plate 46 and the lower pressure plate 47 to move upward, the adjustment plate 44 will be in a state of being away from the lower pressure plate 47 and separated from the lower pressure plate 47 under the action of gravity, so it is easy to adjust its own position. The outer side of the clamping spring 48 is provided with a flexible sleeve 481 which is mainly used to protect the clamping spring 48 to avoid rusting due to long-term use and affecting its service life.

[0028] In order to improve the connection stability between the unloading cylinder 6 and the support tube 3, the present application also has a chamfer 33 provided at the other end of the support tube 3, which can facilitate the support tube 3 to be inserted into the inner cavity of the rubber tube workpiece 2, and a positioning retaining ring 34 is fixed on the inner wall of the support tube 3. The positioning retaining ring 34 is set in two groups, and the two positioning retaining rings 34 of a group are respectively located on both sides of the bearing 62, such as Figure 6 As shown, the positioning retaining ring 34 can be used to position the bearing 62, on the one hand to avoid tilting between the unloading cylinder 6 and the supporting tube 3, and on the other hand to avoid relative displacement between the two.

[0029] In order to transport the rubber tube workpiece 2, the present application also has a guide frame 11 arranged on the front side of the mounting plate 1, and the cross-section of the guide frame 11 is in a "V" shape. The rubber tube workpiece 2 is placed in the inner cavity of the guide frame 11 from top to bottom, and the rubber tube workpiece 2 is transported by an external conveying device and moved in the inner cavity of the guide frame 11. A gap is left between the guide frame 11 and the mounting plate 1. When the rubber tube workpiece 2 is cut, the formed sealing ring is sleeved on the outside of the support tube 3, and the unloading cylinder 6 contracts to drive the support tube 3 to move to the back side of the mounting plate 1. The sealing ring is larger than the support tube 3 in size, so the sealing ring will be blocked by the mounting plate 1 and remain on the front side of the mounting plate 1 until the support tube 3 is completely separated from the sealing ring. The sealing ring can fall from the gap between the guide frame 11 and the mounting plate 1 under the action of gravity. A bracket is fixed on the side of the guide frame 11, and one end of the bracket is fixed to the front side of the mounting plate 1. The bracket is used to fix the guide frame 11.

[0030] In order to protect the cutting assembly 4 and the pressing roller 5, the present application also has a protective cover 8 arranged directly above the rubber tube workpiece 2. The cutting assembly 4 and the pressing roller 5 are both located in the inner cavity of the protective cover 8. The protective cover 8 is used to provide dust protection for the cutting assembly 4 and the pressing roller 5. A window is provided on the surface of the protective cover 8, and a through groove is opened on the front of the protective cover 8. The window allows the staff to observe the inner cavity condition of the protective cover 8. The position of the through groove corresponds to the adjusting member 411. When the adjusting member 411 needs to be manually adjusted, the staff can extend their hands into the inner cavity of the protective cover 8. The protective cover 8 is fixed to the front of the mounting plate 1. A horizontal plate is fixedly installed on the upper surface of the protective cover 8, and the pressing cylinder 7 is fixedly installed on the horizontal plate.

[0031] The present invention also discloses a processing method according to the above-mentioned sealing member cutting processing device, which specifically comprises the following steps: Step 1: transport the rubber tube workpiece 2 to the vicinity of the mounting plate 1, extend the unloading cylinder 6 and drive the supporting cylinder 3 to insert into the inner cavity of the rubber tube workpiece 2, start the pressing cylinder 7 to move the cutting assembly 4 and the pressing roller 5 downward until the cutting assembly 4 and the pressing roller 5 are pressed on the surface of the rubber tube workpiece 2; Step 2: The support cylinder 3 is driven to rotate by the driving assembly, and the support cylinder 3 drives the rubber tube workpiece 2 to rotate by friction.
