Description

Technical Field

[0001] The invention relates to a fully automatic robot with a rubber triangular belt. Background Art

[0002] As an important power transmission component in industrial transmission systems, the cutting process of rubber V-belts in the manufacturing process directly affects the quality and performance of the product. Existing rubber V-belt cutting mainly uses knives for cutting, and this processing method has been widely used in the industry.

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

[0004] However, existing rubber V-belt cutting equipment has obvious technical defects. The main 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 of the cutting area will continue to rise. The heat accumulation phenomenon is more significant during long-term continuous operation.

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

[0006] First, excessively high temperatures can cause thermal deformation of the cutting tool. The tool undergoes microstructural changes at high temperatures, affecting its hardness and toughness, thereby reducing cutting accuracy. Over long periods of time, the tool's geometric dimensions may change slightly, directly affecting cutting quality.

[0007] Secondly, the high temperature in the cutting area will cause thermal damage to the rubber material. Rubber materials are prone to softening, deformation, and partial decomposition at high temperatures, which not only affects the appearance quality of the cut, but also changes the physical properties of the rubber at the edge of the cut, reducing the service life of the product.

[0008] Finally, the increase in temperature will also lead to a decrease in cutting accuracy. When the temperature of the tool and the workpiece increases, the deformation of the material will change accordingly, that is, the thermal expansion effect, causing a 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 problems caused by overheating, operators need to stop the machine regularly for cooling, which not only reduces equipment utilization but also increases production costs.

[0010] Therefore, developing a rubber V-belt cutting device that can effectively control the cutting temperature can solve the problem of heat accumulation and ensure that the tool remains within the appropriate operating temperature range, thereby improving the cutting quality, extending the tool life, and improving production efficiency. Summary of the invention

[0011] The purpose of the present invention is to provide a fully automatic rubber V-belt robot which can solve the problem of heat accumulation of cutting tools, thereby extending the service life of the cutting tools, improving production efficiency and ensuring product consistency.

[0012] The above technical objectives of the present invention are achieved through the following technical solutions:

[0013] A fully automatic robot for rubber V-belts comprises: a frame; a roller shaft and a roller wheel arranged on the frame, the roller wheel is driven by a motor; a positioning plate arranged on the frame; a guide rail arranged transversely on the frame, a sliding seat being slidably connected to the guide rail; a tool holder arranged on the sliding seat, a tool being installed at the end of the tool holder; a positioning frame connected to the frame bearing, the positioning frame being connected to a rotating shaft driven by a motor; a push plate arranged on one side of the positioning frame, a push groove being provided on the push plate; a gear fixedly sleeved on the rotating shaft; a driving rod meshing with the gear and having an end connected to a housing, a fan being provided in the housing; a sliding switch arranged at the bottom of the housing; the gear drives the driving rod to move as the rotating shaft rotates, so that the housing is away from the tool during cutting; a slider is provided at the bottom of the sliding switch, and the slider is fixed to the frame; when the slider moves relatively in the sliding groove of the sliding switch, the fan power is controlled to change; the fan power is reduced during cutting, and the fan power is increased to dissipate heat when the housing is close to the tool after the cutting is completed.

[0014] The present invention is further configured as follows: the rubber belt is conveyed between the roller wheel and the roller shaft by friction; the roller shaft comprises a plurality of roller shafts arranged in sequence, and the roller shaft is connected to the frame by bearings.

[0015] The present invention is further configured as follows: screw rods are arranged at both ends of the guide rail; the screw rods are connected to motor 2 and are used to drive the sliding seat to move laterally along the guide rail for cutting.

[0016] The present invention is further configured as follows: a positioning rod is provided at the end of the tool holder, and the positioning rod is inserted into the push groove; a spring is provided between the positioning rod and the fixing seat for resetting the tool.

[0017] The present invention is further configured as follows: the positioning frame is arranged below the tool and above the positioning plate; when the positioning frame rotates, the end thereof abuts against the edge of the positioning plate to fix the rubber belt; and the motor three is a stepping motor for accurately controlling the rotation angle of the positioning frame.

[0018] The present invention is further configured that: when the positioning frame rotates to fix the rubber belt, the push plate drives the positioning rod to move in the push groove to move the tool down to the cutting position; after the cutting is completed, the spring drives the tool to reset.

[0019] The present invention is further configured as follows: at least two fans are provided and arranged opposite to the position of the cutter; the casing moves in a slide groove provided on the frame through a driving rod; and the slide groove is used to limit the moving direction of the casing.

[0020] The present invention is further configured such that the width of the push groove is greater than the width of the positioning rod, so that the positioning rod has a guiding effect when moving in the push groove.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The present invention arranges a push plate with a push groove on the positioning frame, and inserts the positioning rod at the end of the tool holder into the push groove, so that the positioning frame can rotate and fix the rubber belt while driving the tool to move to the cutting position, thereby solving the problem of low work efficiency caused by the need to perform positioning and cutting step by step in the prior art.

[0023] At the same time, by arranging a structure in which a gear and a driving rod are meshed on the rotating shaft, the casing can automatically reciprocate with the rotation of the positioning frame, and the fan power is controlled by changing the relative position of the slider at the bottom of the sliding switch in the sliding groove. During cutting, the casing 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 the heat accumulation of the tool affects the cutting accuracy and service life.

[0024] Finally, the present invention adopts the control of the rotation of the positioning frame and the guiding effect of the push groove on the positioning rod to improve the positioning accuracy of the rubber belt cutting. The overall structure combines the three functions of positioning, cutting and heat dissipation well. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0038] like Figure 1 As shown, a rubber V-belt fully automatic robot comprises a frame 1.

[0039] like Figure 1 , Figure 2 As shown, in order to solve the problem of rubber belt feeding movement. The rear side of the frame 1 described in the present application is provided with a plurality of roller shafts 2 arranged in sequence. The roller shafts 2 are connected to the frame 1 by bearings. The frame 1 is fixedly provided with a bracket 3 above the roller shaft 2. The bracket 3 is connected with a plurality of roller wheels 4 that cooperate with the roller shaft 2 by bearings. The roller wheels 4 are connected with a motor 5 for driving the roller wheels 4 to rotate, so that the rubber belt is driven to move between the roller wheels 4 and the roller shaft 2 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 holder 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 a 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 with the sliding seat 8. The end of the screw rod 12 is connected with a motor 2 13. The motor 2 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 arranged at one end of the tool holder 10. A spring 15 is arranged between the positioning rod 14 and the fixing seat 9 for resetting the tool holder 10 after the tool holder 10 slides.

[0043] With 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 transversely to obtain the corresponding V-belt.

[0044] like Figure 5 , Figure 6As shown, in order to solve the problem of fixing the rubber belt when cutting the V-belt. The present application is provided with a positioning frame 16 on one side of the positioning plate 6. The positioning frame 16 is arranged below the tool 11 and above the positioning plate 6. One end of the positioning frame 16 is connected to the frame 1 by a bearing. The other end of the positioning frame 16 is connected to a rotating shaft 17. The rotating shaft 17 is connected to 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, thereby driving the positioning frame 16 fixedly connected to the rotating shaft 17 to rotate. When the positioning frame 16 rotates, the end of the positioning frame 16 abuts against the edge of the positioning plate 6, thereby fixing the rubber belt and facilitating the subsequent cutting of the V-belt.

[0045] like Figure 5 , Figure 6 As shown, in order to solve the problem of making the cutter 11 reach the position of the rubber belt for cutting while the positioning frame 16 rotates to fix the rubber belt, the present application provides a push plate 19 on one side of the positioning frame 16. A push groove 20 is provided in the middle of the push plate 19. The positioning rod 14 connected to the end of the tool holder 10 is inserted into 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, it drives the obliquely arranged push plate 19 to rotate, and the positioning rod 14 in the push groove 20 moves in the push groove 20 due to the force of the push plate 19, thereby driving the tool holder 10 to move obliquely downward, and the tool 11 moves to the position of the rubber belt. The motor 2 13 drives the screw rod 12 to rotate to cut the rubber belt into a V-belt.

[0047] In the above process, the spring 15 is compressed, thereby accumulating elastic potential energy, which facilitates the subsequent resetting of the cutter 11. Each time the cutting preparation work is performed, the motor 3 18 is driven to fix the rubber belt for easy cutting, and the cutter 11 can be driven to move down to the rubber belt position, and the cutting preparation work is completed at the same time, thereby improving work efficiency, eliminating the need to set up an additional fixed cylinder, and reducing program design costs.

[0048] like Figure 7 , Figure 8 As shown, in order to solve the technical purpose of removing the heat accumulation of the cutter 11 after each cutting, the present application has a gear 21 fixedly sleeved on the rotating shaft 17. A driving rod 22 is meshed above the gear 21. One end of the driving rod 22 extends and is fixedly connected to a housing 23. At least two fans 24 are arranged on one side of the housing 23. The fan 24 is directly opposite to the position of the cutter 11 and does not affect the movement of the cutter 11 and the rubber belt.

[0049] Correspondingly, a slide slot 25 is provided on the frame 1. The driving rod 22 passes through the slide slot 25 and is connected to the housing 23, thereby limiting and supporting the moving direction of the housing 23.

[0050] A sliding switch 26 is fixedly arranged at the bottom of the housing 23. A slider 27 is arranged at the bottom of the sliding switch 26. A sliding groove 28 is arranged at the sliding switch 26 corresponding to the slider 27. When the slider 27 is at different positions of 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 with a fixing rod 29. The fixing rod 29 is fixedly connected with the frame 1, so that the slider 27 is in a stable and fixed state.

[0052] As mentioned above, when the motor 3 18 works to fix the rubber belt and the cutter 11 moves down to be able to 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, since the slider 27 is fixed, 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 sliding 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 belt is cut once, the rubber belt continues to be fed under the action of the motor 1 5. At this time, the motor 3 18 rotates to reset the positioning frame 16, and the tool 11 is reset under the action of the spring 15. The driving 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 the fan 24 is gradually increased, and the wind speed is increased. The heat accumulated on the tool 11 after cutting is accelerated to dissipate heat under the action of the wind force of the fan 24. In addition, the fan 24 is close to the tool 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 and drive the tool 11 to move to the cutting position at the same time, thereby solving the problem of low work efficiency caused by the need to perform positioning and cutting step by step in the prior art.

[0055] At the same time, by setting a structure in which a gear 21 and a driving rod 22 are meshed on the rotating shaft 17, the casing 23 can automatically reciprocate 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 the heat accumulation of the tool 11 affects the cutting accuracy and service life.

[0056] Finally, the present invention improves the positioning accuracy of the rubber belt cutting by controlling the rotation of the positioning frame 16 and cooperating with the guiding effect of the push groove 20 on the positioning rod 14. The overall structure combines the three functions of positioning, cutting and heat dissipation well.

[0057] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
