Description

Technical Field

[0001] The present invention relates to the technical field of hose processing, and more particularly to an automatic cutting device for hoses. Background Art

[0002] A hose is a tubular rubber product used to transport gases, liquids, slurries, or granular materials. It consists of inner and outer rubber layers and a skeleton layer. The skeleton layer can be made of cotton fiber, various synthetic fibers, carbon fiber, or asbestos. The inner and outer layers of hoses are typically made of natural rubber, styrene-butadiene rubber, or butadiene rubber. Common hoses include water pipes, hot water pipes, steam pipes, food and beverage pipes, air pipes, welded pipes, gas pipes, ventilation pipes, and oil pipes.

[0030] Example 1:

[0031] See also Figure 1-5 and Figure 6-7, an automatic cutting device for a rubber hose, comprising a support base 1 and a cutting mechanism 2, wherein the upper end of the support base 1 is fixedly connected to two fixing rings 3, a rotating ring 4 is slidably connected between the two fixing rings 3, the cutting mechanism 2 mainly comprises an electric push rod mounted on the inner wall of the rotating ring 4, a cutting knife and a motor for driving the cutting knife to rotate are mounted on the telescopic end of the electric push rod, a driving mechanism 5 for driving the rotating ring 4 to rotate is provided at the upper end of the support base 1, a support column 6 is provided inside the fixing ring 3, the support column 6 is connected to an adjustable telescopic rod, and two inner support plate groups are provided on the side wall of the support column 6, each inner support plate group comprises a plurality of inner support plates 7 distributed in a ring array, and a transmission cavity 10 is opened inside the support column 6 The inner wall of the transmission cavity 10 is provided with multiple supporting mechanisms 8 connected to the inner support plates 7. The interior of the transmission cavity 10 is provided with a transmission mechanism 9 that drives the multiple inner support plates 7 to move up and down. A circular slide groove 34 is provided on the side of the fixed ring 3 close to the rotating ring 4. The inner wall of the circular slide groove 34 is slidably connected with multiple sliding arc plates 35. The end of the sliding arc plate 35 away from the circular slide groove 34 is fixedly connected to the outer wall of the rotating ring 4. The rotating ring 4 can slide along the circular slide groove 34 through the sliding arc plate 35. The outer wall of the support column 6 is provided with an annular cutting groove 33. The annular cutting groove 33 is located between the two inner support plate groups. The annular cutting groove 33 facilitates the cutting of the hose by the cutting mechanism 2 while avoiding damage to the support column 6.

[0032] When using this device, the open end of the hose to be cut is placed into the inner ring of the fixed ring 3 and the rotating ring 4, and the open end of the hose is inserted into the outside of the support column 6. At this time, the support column 6 is located inside the hose, and the position of the annular cutting groove 33 of the support column 6, that is, the incision position, is located in the middle position of the fixed rings 3 on both sides, and is also located at the cutting position of the cutting mechanism 2. When the position of the hose to be cut is moved to the incision position of the support column 6, that is, the annular cutting groove 33, the inner support plate 7 contacts the inner wall of the hose through the cooperation of the transmission mechanism 9 and the support mechanism 8, thereby supporting the inner walls on both sides of the hose cutting position, thereby ensuring the stability of the hose cutting position. The cutting knife is then rotated by the cutting mechanism 2 and extended to contact the cutting position of the hose, and then the driving mechanism 5 drives the rotating ring 4 to rotate. When the rotating ring 4 rotates, it drives the cutting mechanism 2 to rotate and cut the hose around one circle, so that the cutting part of the hose can be completely cut off. The cutting is simple and convenient, avoiding the current situation of pressing down to cut the hose by the cutting knife. At the same time, by supporting the inner walls on both sides of the cutting part of the hose, the deformation problem of the hose at a limited position when the hose is currently cut can be avoided. At the same time, the deformation problem of the hose when the hose is currently pressed down to cut is avoided, and the situation of uneven incision and deviation in cutting position is greatly avoided, thereby improving the cutting effect and cutting quality of the hose; at the same time, by supporting and fixing the inner walls on both sides of the cutting part of the hose, the hose is fixed firmly, which greatly avoids the situation that the hose will be displaced during cutting, thereby greatly improving the stability and accuracy of cutting, and meeting the cutting requirements for the hose.

[0033] In this embodiment, preferably, please refer to Figure 1 The drive mechanism 5 includes a drive motor 501 fixedly mounted on the upper end of the support base 1. The output end of the drive motor 501 is fixedly connected to a driving gear 502. The outer wall of the rotating ring 4 is fixedly sleeved with a driven ring gear 503 that meshes with the driving gear 502. When the drive motor 501 is started, the driving gear 502 moves. The driving gear 502, in turn, drives the rotating ring 4 to rotate through the cooperation with the driven ring gear 503. The rotation of the rotating ring 4 drives the cutting mechanism 2 to rotate in a circular motion, thereby enabling the cutting mechanism 2 to perform rotary cutting on a circumference of the hose.

[0034] In this embodiment, preferably, please refer to Figure 5 and Figure 6-7 The support mechanism 8 includes a first spring 801 fixedly connected to the inner wall of the transmission chamber 10, the movable end of the first spring 801 is fixedly connected to the first wedge block 802, the outer wall of the first wedge block 802 is fixedly connected to the first connecting rod 803, the other end of the first connecting rod 803 movably passes through the outer wall of the support column 6 and is connected to the inner support plate 7, the transmission mechanism 9 includes an electric telescopic rod 901 fixedly installed on the inner wall of the transmission chamber 10, the telescopic end of the electric telescopic rod 901 is fixedly connected to the transmission rod 902, and the outer wall of the transmission rod 902 is fixedly connected to two groups of second wedge blocks 903, and each second wedge block 903 is slidably adapted to its corresponding first wedge block 802. The electric telescopic rod 901 is started to extend the transmission rod 902, and the transmission rod 902 will drive the second wedge block 903 to move to the left. The second wedge block 903 will make the first wedge block 802 move away from the transmission rod 902. At the same time, the first wedge block 802 will compress the first spring 801 and drive the first connecting rod 803 to move toward the outside of the support column 6. That is, the first connecting rods 803 on both sides will drive the two sets of inner support plates 7 to move away from the support column 6. Figure 7 As shown, the inner support plates 7 will move toward the inner wall of the hose, and eventually the inner support plates 7 will contact the inner wall of the hose, thereby supporting the inner walls on both sides of the hose cutting position through the two groups of inner support plates 7.

[0035] Example 2:

[0036] Based on Example 1, please refer to Figure 4-7, the inner wall of the transmission cavity 10 is fixedly connected to a plurality of second springs 11, the movable end of the second spring 11 is fixedly connected to a third wedge block 12, the outer wall of the transmission rod 902 is fixedly connected to a plurality of fourth wedge blocks 13 that are slidably adapted to the third wedge blocks 12, the outer wall of the third wedge block 12 is fixedly connected to a second connecting rod 14, the other end of the second connecting rod 14 movably passes through the outer wall of the support column 6 and is provided with a mounting bracket 15, and a guide wheel 16 is rotatably connected to the mounting bracket 15. Initially, when the hose is not inserted, the fourth wedge block 13 on the transmission rod 902 will pass through the third wedge block 12 to move the second connecting rod 14 and the guide wheel 16 away from the outer wall of the support column 6. At this time, the distance between the guide wheel 16 and the support column 6 is greater than the distance between the inner support plate 7 and the support column 6, such as Figure 4-5 As shown, when the hose is inserted into the outer surface of the support column 6, the inner wall of the hose opening first contacts the guide wheel 16. At this time, the guide wheel 16 facilitates the insertion of the hose, greatly avoiding the situation where the hose will bend during insertion, which makes it difficult to insert the hose. This greatly reduces the time and effort required to insert the hose, while making the insertion more stable, further improving the effect and efficiency of the hose cutting. When the hose is moved to the designated position, the electric telescopic rod 901 drives the transmission rod 902 to move. When the transmission rod 902 moves, it also drives the fourth wedge block 13 to move. Then, the action of the second spring 11 causes the third wedge block 12 and the second connecting rod 14 to move toward the transmission rod 902, which in turn drives the mounting bracket 15 and the guide wheel 16 toward the outer wall of the support column 6. Finally, when the inner wall of the hose is supported by the inner support plate 7, the guide wheel 16 does not contact the inner wall of the hose, which greatly avoids the instability of the hose during cutting.

[0037] Example 3:

[0038] Based on Example 1, please refer to Figure 4-5 and Figure 8-11A connecting assembly 21 is provided between the first connecting rod 803 and the inner support plate 7 and between the second connecting rod 14 and the mounting bracket 15. The connecting assembly 21 includes a mounting seat 22 and a plug column 23 slidably connected to the inner wall of the mounting seat 22. A plurality of third springs 24 are fixedly connected to the bottom of the inner cavity of the mounting seat 22. The movable end of the third spring 24 is fixedly connected to the support plate 25. The outer wall of the mounting seat 22 is symmetrically provided with a limit assembly for limiting the plug column 23. The limit assembly includes a slide penetrating the mounting seat 22. 2. A limiting rod 26 is formed on the outer wall of the plug post 23. A limiting groove 27 adapted to the limiting rod 26 is formed on the outer wall of the plug post 23. An auxiliary block 28 is fixedly connected to the outer end of the limiting rod 26. A plurality of fourth springs 29 are fixedly installed between the auxiliary block 28 and the outer wall of the mounting seat 22. Two grooves 30 are formed on the outer wall of the limiting rod 26. A blocking rod 31 is hingedly connected to the side wall of the groove 30. A fifth spring 32 is fixedly installed between the blocking rod 31 and the inner wall of the groove 30. Two limiting grooves 17 are symmetrically formed on the left and right walls of the mounting seat 22.

[0039] When the inner wall of the hose is supported by the inner support plate 7, the supporting force of the inner support plate 7 on the hose also causes the hose to generate a reaction force on the inner support plate 7, which can drive the plug column 23 connected to the inner support plate 7 to move to a certain extent. The plug column 23 will compress the support plate 25 and the third spring 24, which can buffer the inner support plate 7 and prevent the rigid supporting force of the inner support plate 7 on the hose from causing large deformation of the hose.

[0040] When the supporting force of the inner support plate 7 on the rubber tube is greater at this time, the reaction force will cause the plug post 23 to move more toward the inside of the mounting seat 22, and the plug post 23 will move downward to squeeze the limiting rod 26 through the upper end of the limiting groove 27, and finally cause the limiting rod 26 to move toward the outside. When the supporting force of the inner support plate 7 on the rubber tube exceeds the allowable value within the range, the limiting rod 26 will disengage from the limiting groove 27. Figure 10As shown, at this time, the fifth spring 32 in the groove 30 will make the blocking rod 31 pop out, and then the blocking rod 31 will contact the outer wall of the mounting seat 22 and enter the limiting groove 17, and the limiting groove 17 will limit the return of the limiting rod 26. After cutting, when the support of the inner support plate 7 for the hose is contacted, that is, when the inner support plate 7 moves away from the hose, the plug post 23 loses the limitation of the limiting rod 26 and falls out of the mounting seat 22. At this time, it can be known that the inner support plate 7 is not suitable for the support of the current hose, so it is necessary to replace it with a shorter inner support plate 7 for use. Then insert the plug post 23 on the replaced inner support plate 7 into the mounting seat 22, pull the limit rod 26 outward and then press the blocking rod 31 to make it enter the groove 30, and then the limit rod 26 will be moved by the fourth spring 29, and finally enter the limit groove 27 of the plug post 23, and the replacement is completed. It can clearly and intuitively remind the operator to replace the inner support plate 7, avoiding the use of inappropriate inner support plate 7 to cause greater deformation damage to the hose and affect the cutting accuracy, and the use effect is good; at the same time, different inner support plates 7 can also be replaced according to the cutting of different hoses.

[0041] Working principle: When using this device, the open end of the hose to be cut is placed into the inner ring of the fixed ring 3 and the rotating ring 4. At this time, the support column 6 is located inside the hose, and the position of the annular cutting groove 33 of the support column 6, that is, the cutting position, is located in the middle position of the fixed rings 3 on both sides, and is also located at the cutting position of the cutting mechanism 2. When the position of the hose to be cut is moved to the cutting position of the support column 6, that is, the annular cutting groove 33, the electric telescopic rod 901 is started to drive the transmission rod 902 to extend, and the transmission rod 902 will drive the second wedge block 903 to move to the left, and the second wedge block 903 will cause the first wedge block 802 to move in the direction away from the transmission rod 902. The first wedge block 802 will also compress the first spring 801 and drive the first connecting rod 803 to move toward the outside of the support column 6, that is, the first connecting rods 803 on both sides will drive the two groups of inner support plates 7 to move in the direction away from the support column 6. Figure 7 As shown, the inner support plate 7 will move toward the inner wall of the hose, and eventually the inner support plate 7 will contact the inner wall of the hose, thereby supporting the inner walls on both sides of the hose cutting position through the two sets of inner support plates 7, which can ensure the stability of the hose cutting position. Then, the cutting knife is rotated by the cutting mechanism 2 and extended to contact the cutting position of the hose. At the same time, the driving motor 501 is started to drive the driving gear 502 to move. The driving gear 502 will drive the rotating ring 4 to rotate by cooperating with the driven gear ring 503. When the rotating ring 4 rotates, it will drive the cutting mechanism 2 to rotate in a circle, so that the cutting mechanism 2 can rotate and cut the hose around one circle, that is, the cutting position of the hose can be completely cut off. The cutting is simple and convenient, and can avoid the deformation, uneven incision and cutting position deviation of the hose during the current hose cutting, greatly improving the cutting effect and cutting quality of the hose.

[0042] Initially, when the hose is not inserted, the fourth wedge block 13 on the transmission rod 902 will move the second connecting rod 14 and the guide wheel 16 away from the outer wall of the support column 6 through the third wedge block 12. At this time, the distance between the guide wheel 16 and the support column 6 is greater than the distance between the inner support plate 7 and the support column 6. When the hose is put on the outside of the support column 6, the inner wall of the hose opening first contacts the guide wheel 16. At this time, the guide wheel 16 can facilitate the insertion of the hose, greatly reducing the time and effort required for inserting the hose, and making the insertion more stable. When the hose moves to the specified position, the transmission rod 902 is driven to move by the electric telescopic rod 901. When the transmission rod 902 moves, the fourth wedge block 13 is driven to move at the same time. Then, the third wedge block 12 and the second connecting rod 14 are moved toward the direction close to the transmission rod 902 through the action of the second spring 11, which drives the mounting frame 15 and the guide wheel 16 to move toward the outer wall of the support column 6. Finally, when the inner wall of the hose is supported by the inner support plate 7, the guide wheel 16 does not contact the inner wall of the hose.

[0043] When the inner wall of the hose is supported by the inner support plate 7, the support force of the inner support plate 7 on the hose also causes the hose to generate a reaction force on the inner support plate 7, which can drive the plug 23 connected to the inner support plate 7 to move to a certain extent. The plug 23 will compress the support plate 25 and the third spring 24, which can cushion the inner support plate 7 and prevent the rigid support force of the inner support plate 7 on the hose from causing a large deformation of the hose. When the support force of the inner support plate 7 on the hose is relatively large at this time, the plug 23 will be displaced more toward the inside of the mounting seat 22 through the reaction force. The downward movement of the plug 23 will squeeze the limit rod 26 through the upper end of the limit groove 27, and eventually the limit rod 26 will move toward the outside. When the support force of the inner support plate 7 on the hose exceeds the allowable value within the range, the limit rod 26 will be separated from the limit groove 27. Figure 10-11 As shown, at this time, the fifth spring 32 in the groove 30 will cause the blocking rod 31 to pop out, and then the blocking rod 31 will contact the outer wall of the mounting seat 22 and enter the limit groove 17, and the limit groove 17 will be used to limit the return of the limit rod 26. After cutting, after contacting the support of the inner support plate 7 for the hose, that is, when the inner support plate 7 moves away from the hose, the plug post 23 loses the limitation of the limit rod 26 and will fall out of the mounting seat 22. At this time, it can be known that this inner support plate 7 is not suitable for the support of the current hose. Then, the plug post 23 on the replaced inner support plate 7 is inserted into the mounting seat 22, and the limit rod 26 is pulled outward and then the blocking rod 31 is pressed to make it enter the groove 30. Then the limit rod 26 is moved by the fourth spring 29, and finally enters the limit groove 27 of the plug post 23, and the replacement is completed. At the same time, the auxiliary block 28 can be manually pulled to disengage the limiting rod 26 from the limiting groove 27, and then the plug post 23 and the inner support plate 7 can be pulled out for manual replacement.
