Description

Technical Field

[0001] The utility model relates to an automatic V-belt cutting machine. Background Art

[0002] A cutting machine is a mechanical device used to cut materials. It can cut various raw materials such as rubber, fabric, leather, paper, plastic, etc. into specific shapes and sizes. In the production process of V-belts, the cutting machine is mainly used to cut the calendered rubber sheets into the required width and length for subsequent molding and vulcanization processes. The type and function of the cutting machine can vary depending on the specific application and cutting requirements.

[0003] Existing V-belts are generally made by first extruding a rubber sheet and cutting the rubber sheet into a rubber belt, and then cutting it into a suitable length by a cutting machine, and then vulcanizing and surface treating it to obtain a finished V-belt.

[0004] The existing cutting machine's cutter and rubber belt stretching machine both need to be independently driven by a cylinder or other driving device. After the stretching device stretches the rubber belt to a certain length, the cutter moves down to cut the rubber belt to obtain a V-belt of a certain specification. The above process needs to be intelligently controlled, and the testing and design costs required for its operation are high, and it is prone to failure. Utility Model Content

[0005] The utility model aims to provide an automatic V-belt cutting machine, which has the characteristics of low testing cost and low failure rate.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] The cam-type transmission mechanism is a kind of V-belt automatic cutting machine, comprising: a frame; a winding reel arranged on one side of the frame; a fixed column arranged in the middle of the frame; a slide seat slidably arranged on the fixed column; a cutting knife arranged at the bottom of the slide seat; a knife pad arranged on the frame and located below the cutting knife; a hydraulic cylinder connected to the knife pad; two clamping blocks arranged on the frame and located on one side of the cutting knife; a cylinder for driving the two clamping blocks to move towards each other; a sliding seat fixedly connected to the bottom of the cylinder; a conveyor belt arranged on one side of the sliding seat and used to make the sliding seat slide back and forth; a motor connected to the conveyor belt; and further comprising: a connecting plate arranged on one side of the sliding seat; a driving rod fixedly connected to the connecting plate; a driving wheel meshed with the top of the driving rod; a rotating shaft fixedly penetrated through the middle of the driving wheel, and the rotating shaft and the frame are connected by a bearing; a driven wheel arranged at one end of the rotating shaft, and the diameter of the driven wheel is smaller than the diameter of the driving wheel; a driven rod meshed with one side of the driven wheel; a connecting seat fixedly connected to the driven rod, and the connecting seat is fixedly connected to the sliding seat.

[0008] The utility model is further configured as follows: the angular velocity of the driven wheel is equal to that of the driving wheel.

[0009] The utility model is further configured as follows: the hydraulic cylinder is used to drive the knife pad to move upwards until it abuts against the cutting knife.

[0010] The utility model is further configured that: the motor is used to drive the clamping block to move horizontally.

[0011] The utility model is further configured that a rubber belt can be wound around the winding reel.

[0012] The utility model is further configured as follows: the driving rod moves to drive the driving wheel to rotate, so that the rotating shaft rotates, the rotating shaft rotates to drive the driven wheel to rotate, so that the driven rod moves downward, and the movement of the driven rod drives the cutter to move downward.

[0013] The utility model is further configured that: when the rubber belt is stretched to the end of the frame, the cutter reaches the cutting position of the rubber belt.

[0014] The utility model is further arranged that: the knife pad moves upward under the action of the hydraulic cylinder to cut the rubber belt.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. Low testing cost: By synchronizing the downward movement of the cutter with the stretching process of the rubber belt, the program steps required for testing are reduced, thereby reducing the cost of CNC testing.

[0017] 2. Low failure rate: Compared with the existing technology, this design simplifies the control process and reduces the number of independent drive devices, thereby reducing the possibility of failure in subsequent use.

[0018] 3. High cutting precision: The design of the driving wheel and the driven wheel ensures that when the rubber belt is stretched to the end of the frame, the cutter reaches the cutting position just in time, ensuring that the length of the rubber belt is consistent each time it is cut.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0026] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 As shown, an automatic V-belt cutting machine includes a frame 1. A winding disk 2 is arranged on one side of the frame 1. A rubber belt can be wound on the winding disk 2. Correspondingly, a fixed column 3 is arranged in the middle of the frame 1. A slide 4 is slidably arranged on the fixed column 3. A cutter 5 is arranged at the bottom of the slide 4. Corresponding to the lower part of the cutter 5, a knife pad 6 is also arranged on the frame 1. The knife pad 6 is connected to a hydraulic cylinder 7 for driving the knife pad 6 to move upward to abut against the cutter 5.

[0029] The frame 1 is provided with two clamping blocks 8 on one side of the cutter 5. The two clamping blocks 8 are driven by a cylinder 9 to move toward each other to clamp one end of the rubber belt. A sliding seat 10 is fixedly connected to the bottom of the cylinder 9. A conveyor belt 11 is provided on one side of the sliding seat 10 to enable the sliding seat 10 to slide back and forth. The conveyor belt 11 is connected to a motor 12 to drive the clamping blocks 8 to move horizontally.

[0030] The above is prior art and will not be described in detail.

[0031] The core technical solution of this application is as follows:

[0032] like Figure 3 , Figure 4 As shown, in order to achieve the technical purpose of making the process of the cutter 5 and the clamping block 8 clamping the rubber belt and stretching the rubber belt simultaneously, the failure rate is reduced.

[0033] The present application provides a connecting plate 13 on one side of the sliding seat 10. The connecting plate 13 is fixedly connected to a driving rod 14. A driving wheel 15 is meshed on the top of the driving rod 14. A rotating shaft 16 is fixedly penetrated through the middle of the driving wheel 15. The rotating shaft 16 is connected to the frame 1 by a bearing. Among them, a driven wheel 17 is connected to one end of the rotating shaft 16. The diameter of the driven wheel 17 is smaller than the diameter of the driving wheel 15. A driven rod 18 is meshed on one side of the driven wheel 17. The driven rod 18 is fixedly connected to a connecting seat 19. The connecting seat 19 is fixedly connected to the sliding seat 4.

[0034] Through the above arrangement, the rubber belt on the winding disk 2 is pulled out to the side of the cutter 5. After that, the clamping block 8 clamps the rubber belt through the cylinder 9. The motor 12 is started to move the conveyor belt 11, and the conveyor belt 11 moves, which drives the driving rod 14 to move. The movement of the driving rod 14 drives the driving wheel 15 to rotate, thereby rotating the rotating shaft 16. The rotation of the rotating shaft 16 drives the driven wheel 17 to rotate, so that the driven rod 18 moves downward, and the movement of the driven rod 18 drives the cutter 5 to move downward.

[0035] As described above, since the angular velocities of the driven wheel 17 and the driving wheel 15 are equal, when they rotate the same number of times, the driving wheel 15 travels a longer distance, so that when the rubber belt is stretched to the end of the frame 1, the cutter 5 reaches the cutting position of the rubber belt. At this time, the knife pad 6 moves up under the action of the hydraulic cylinder 7 to cut the rubber belt.

[0036] Repeating the above steps ensures that the length of the rubber belt cut each time remains consistent, and reduces the number of program steps required for testing, thereby reducing the cost of CNC testing. In subsequent use, the failure rate is reduced compared to the prior art.

[0037] 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, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
