Description

TECHNICAL FIELD

[0001] The present application relates to a full-automatic robot for rubber V-belt. BACKGROUND

[0002] As an important power transmission component in industrial transmission systems, the cutting process of rubber V-belt directly affects the quality and performance of the product. The existing rubber V-belt cutting mainly uses cutting tools for cutting, which has been widely used in the industry.

[0003] The existing rubber V-belt cutting process is usually as follows: first, fix the continuous rubber belt on the cutting platform; then start the cutting equipment, and make the cutter cut according to the preset cutting line; control the feeding speed of the rubber belt through the feeding mechanism to realize continuous cutting operation. During the cutting process, the speed of the cutter is usually kept at a high level to ensure the flatness and cutting efficiency of the cut.

[0004] However, the existing rubber V-belt cutting equipment has obvious technical defects. The most important problem is that the heat generated during the cutting process is difficult to dissipate in time. Due to the intense friction between the cutter and the rubber material, the temperature in the cutting area continues to rise. The heat accumulation phenomenon is more significant during long-time continuous operation.

[0005] The negative effects of heat accumulation are mainly as follows:

[0006] First, the excessively high temperature will cause the cutting tool to produce thermal deformation. The microstructure of the cutting tool changes under high temperature, affecting its hardness and toughness, thereby reducing the cutting precision. Under long-time work, the geometric size of the cutting tool may change slightly, directly affecting the cutting quality.

[0007] Secondly, the high temperature in the cutting area will cause thermal damage to the rubber material. The rubber material is easy to soften, deform, and partially decompose under high temperature, which not only affects the appearance quality of the cut, but also changes the physical properties of the rubber at the cut edge, reducing the service life of the product.

[0008] Finally, the temperature rise will also cause the cutting precision to decrease. When the temperature of the cutter and the workpiece rises, the deformation of the material will change, i.e. thermal expansion effect, causing the deviation between the actual cutting size and the designed size, resulting in poor product consistency.

[0009] In terms of production efficiency, in order to avoid the problems caused by overheating, the operator needs to stop cooling regularly, which not only reduces the utilization rate of the equipment, but also increases the production cost.

[0010] Therefore, the rubber V-belt cutting device capable of effectively controlling the cutting temperature can solve the heat accumulation problem, ensure that the cutter is kept in a suitable working temperature range, thereby improving the cutting quality, prolonging the service life of the cutter and improving the production efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] The present application will be further described in detail below in conjunction with the drawings.

[0038] AsFigure 1 As shown, a rubber triangular belt fully automatic robot includes a frame 1.

[0039] like Figure 1 、 Figure 2 As shown, in order to solve the problem of rubber belt feeding movement, the frame 1 described in this application is provided with a plurality of rollers 2 arranged in sequence on the rear side. The rollers 2 are connected to the frame 1 by bearings. The frame 1 is fixedly provided with a bracket 3 above the rollers 2. The bracket 3 is connected to a plurality of rollers 4 that cooperate with the rollers 2 by bearings. The rollers 4 are connected to a motor 5 for driving the rollers 4 to rotate, thereby causing the rubber belt to move between the rollers 4 and the rollers 2, driven by friction.

[0040] like Figure 2 、 Figure 3 、 Figure 4 As shown, in order to solve the problem of cutting the rubber belt into a V-belt. The present application is provided with a positioning plate 6 on one side of the bracket 3. The positioning plate 6 is fixedly connected to the frame 1. The positioning plate 6 is used as a cutting workbench when the rubber belt moves onto the positioning plate 6. Correspondingly, a transversely arranged guide rail 7 is fixedly provided on the frame 1. A sliding seat 8 is slidably connected to the guide rail 7. A fixed seat 9 is fixedly provided on one side of the sliding seat 8. A tool holder 10 is slidably penetrated on one side of the fixed seat 9. A tool 11 is provided at the end of the tool holder 10. The tool 11 is used to cut the rubber belt, and the tool 11 is adjusted and replaced to the corresponding shape according to the required V-belt shape.

[0041] Optimally, a screw rod 12 is provided between the two ends of the guide rail 7, and the screw rod 12 is connected to the sliding seat 8. The end of the screw rod 12 is connected to a second motor 13. The second motor 13 is used to drive the screw rod 12 to rotate, thereby driving the sliding seat 8 on the guide rail 7 to slide along the guide rail 7 in the horizontal direction.

[0042] A positioning rod 14 is fixedly provided at one end of the tool holder 10. A spring 15 is provided between the positioning rod 14 and the fixing seat 9 for resetting the tool holder 10 after it slides.

[0043] Through the above arrangement, when the tool 11 moves obliquely downward with the tool holder 10 to contact the conveyed rubber belt, the motor 2 13 drives the sliding seat 8 to move along the guide rail 7, thereby cutting the rubber belt horizontally to obtain the corresponding V-belt.

[0044] like Figure 5 、 Figure 6As shown in the drawings, in order to solve the problem of fixing the rubber belt when cutting the triangular belt. The positioning plate 6 is provided with a positioning frame 16 on one side. The positioning frame 16 is arranged below the cutter 11 and above the positioning plate 6. One end of the positioning frame 16 is connected with the bearing between the rack 1. The other end of the positioning frame 16 is connected with a rotating shaft 17. The rotating shaft 17 is connected with a motor three 18. The motor three 18 is a stepping motor. The rotating shaft 17 can be driven to rotate by the motor three 18, and then the positioning frame 16 fixedly connected with the rotating shaft 17 is driven to rotate. When the positioning frame 16 rotates, the end of the positioning frame 16 abuts against the edge position of the positioning plate 6, so as to fix the rubber belt, which is convenient for subsequent cutting of the triangular belt.

[0045] As shown in the drawings, Figure 5 , Figure 6 In order to solve the problem that the cutter 11 reaches the position of the rubber belt for cutting while the positioning frame 16 rotates to fix the rubber belt. The application is provided with a push plate 19 on one side of the positioning frame 16. The push plate 19 is provided with a push groove 20 in the middle. The positioning rod 14 connected with the cutter holder 10 is arranged in the push groove 20. The width of the push groove 20 is greater than the width of the positioning rod 14.

[0046] When the positioning frame 16 rotates, the obliquely arranged push plate 19 is driven to rotate, and the positioning rod 14 in the push groove 20 is moved in the push groove 20 under the action of the push plate 19, so as to drive the cutter holder 10 to move obliquely downward, and the cutter 11 moves to the position of the rubber belt. The rubber belt is cut into a triangular belt by driving the lead screw 12 to rotate by the motor two 13.

[0047] In the above process, the spring 15 is compressed, and then the elastic potential energy is accumulated, which is convenient for subsequent reset of the cutter 11. When preparing for cutting each time, the motor three 18 is driven to fix the rubber belt for cutting on one hand, and to drive the cutter 11 to move downward to the position of the rubber belt on the other hand, so as to complete the cutting preparation work and improve the work efficiency. There is no need to additionally set a fixing air cylinder, which reduces the program design cost.

[0048] As shown in the drawings, Figure 7 , Figure 8 In order to solve the technical problem of removing the heat accumulation of the cutter 11 after each cutting. The gear 21 is fixedly arranged on the rotating shaft 17. The driving rod 22 is engaged above the gear 21. The driving rod 22 is extended and fixedly connected with the machine shell 23 on one end. The machine shell 23 is provided with at least two fans 24 on one side. The fans 24 are opposite to the position of the cutter 11 and do not affect the movement of the cutter 11 and the rubber belt.

[0049] Correspondingly, the rack 1 is provided with a sliding groove 25. The driving rod 22 passes through the sliding groove 25 and is connected with the machine shell 23, so as to limit the moving direction of the machine shell 23 and play a supporting role.

[0050] A sliding switch 26 is fixedly mounted at the bottom of the housing 23. A slider 27 is mounted at the bottom of the sliding switch 26. A sliding groove 28 is provided in the sliding switch 26 corresponding to the slider 27. When the slider 27 is in different positions in the sliding groove 28, the fan 24 electrically connected to the sliding switch 26 has different operating powers.

[0051] The slider 27 is fixedly connected to a fixing rod 29. The fixing rod 29 is fixedly connected to the frame 1 so that the slider 27 is in a stable and fixed state.

[0052] As described above, when the motor 3 18 is working to fix the rubber belt and the cutter 11 moves down to the point where it can cut the rubber belt, the gear 21 rotates, driving the drive rod 22 to move in a direction away from the cutter 11. While the drive rod 22 slides in the slide groove 25, the slider 27 is fixed, and the housing 23 moves, so that the slider 27 is in the closed position of the sliding switch 26. In the process of moving to the end of the slide groove 28, the power of the fan 24 gradually decreases, causing the wind speed to decrease until it is turned off. At this time, the normal cutting process of the rubber V-belt will not be affected by the wind speed, thereby improving the cutting accuracy. In addition, the housing 23 is away from the cutter 11, so that the movement of the cutter 11 will not be affected by the housing 23, thereby improving the cutting stability.

[0053] Correspondingly, after the rubber strip is cut once, it continues to be fed by motor 1 5. At this time, motor 3 18 rotates to reset the positioning frame 16, and under the action of spring 15, the cutter 11 is reset. The drive rod 22 drives the housing 23 to reset. At this time, the housing 23 moves so that the slider 27 of the sliding switch 26 gradually resets relative to the sliding groove 28. The power of fan 24 gradually increases, and the wind speed increases. The accumulated heat on the cutter 11 after the cut is quickly dissipated by the wind force of fan 24. In addition, the fan 24 is close to the cutter 11, which improves the heat dissipation effect.

[0054] In summary, the present invention arranges a push plate 19 with a push groove 20 on the positioning frame 16, and inserts the positioning rod 14 at the end of the tool holder 10 into the push groove 20, so that the positioning frame 16 can rotate the fixed rubber belt while driving the tool 11 to move to the cutting position, thereby solving the problem of low work efficiency caused by the need to perform positioning and cutting in steps in the prior art.

[0055] At the same time, by setting a structure in which a gear 21 and a drive rod 22 are meshed on the rotating shaft 17, the casing 23 can automatically move back and forth with the rotation of the positioning frame 16, and the power of the fan 24 is controlled by changing the relative position of the slider 27 at the bottom of the sliding switch 26 in the sliding groove 28. During cutting, the casing 23 automatically moves away to avoid affecting the cutting, and automatically moves closer to dissipate heat after the cutting is completed, thereby solving the problem in the prior art that heat accumulation of the tool 11 affects the cutting accuracy and service life.

[0056] Finally, the application adopts control positioning frame 16 rotation, cooperation with the push slot 20 to the positioning rod 14 guide effect, improve the positioning accuracy of rubber belt cutting. The overall structure will be better combined with the positioning, cutting, heat dissipation three functions.

[0057] The specific embodiment is only an explanation of the application, which is not a limitation of the application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the application, it is protected by the patent law.
