Abstract

The utility model discloses a silica gel product cutting machine capable of intermittently conveying, which comprises a support frame, a cutting device and a driving device, and the cutting device comprises a cutter. When the silica gel product is cut, the silica gel product is continuously conveyed to the position below the cutter through the conveying belt, and the cutter conducts reciprocating motion so as to cut the silica gel product into the silica gel product with the specific length or width. In the process, an output shaft of a driving motor drives a driving wheel to do constant-speed circular motion, and the driving wheel drives an inner gear to do intermittent circular motion, so that a first rotating shaft is driven to do intermittent circular motion, and then intermittent motion of a conveying belt is achieved, namely intermittent conveying of the silica gel products is achieved. In the cutting process that the cutter makes contact with the silica gel product and the cutter is separated from the silica gel product, the conveying belt stops moving, the silica gel product is prevented from being subjected to forward movement acting force under the action of the conveying belt when the silica gel product is cut, and therefore mechanical abrasion is reduced, the cutting precision of the silica gel product is improved, and deformation of a notch of the silica gel product is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of cutting silicone products, in particular to a silicone product cutting machine capable of intermittent transmission. Background Art

[0002] Products made with silicone as the main raw material are called silicone products. A silicone product cutting machine can cut silicone products into products of a specific width to meet the requirements of different working conditions. For example, silicone plates or silicone tubes can be made into silicone products of a specific length or width by placing the silicone plates or silicone tubes on a conveyor belt and cutting them in sections. These silicone products can be used for sealing, heat insulation, protection of electronic components and other industrial applications. When the existing silicone product cutting machine cuts silicone products (such as silicone plates or silicone tubes), it mainly places the silicone products to be cut on a conveyor belt, which is continuously transported to the cutter by the conveyor belt; the cutter is set above the conveyor belt and is used to cut silicone products. However, when the cutter moves downward and cuts the silicone product, the conveyor belt keeps moving. Although the silicone product is stationary due to the pressure of the cutter, the silicone product is still subjected to the force of moving forward under the action of the conveyor belt, which not only leads to increased mechanical wear, but also causes problems such as inaccurate cutting of silicone products, uneven edge cutting and deformation of silicone product cuts, thereby affecting the precision and product quality of silicone products. Therefore, a silicone product cutting machine with intermittent transmission is proposed. Utility Model Content

[0024] In order to make the purpose, features and advantages of the invention of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] Reference Figures 1 to 3 The embodiment of the utility model provides a silicone product cutting machine capable of intermittent transmission, comprising a support frame 10, a driving device 30 and a cutting device 20. The support frame 10 is provided with a conveyor belt 11 for conveying silicone products (such as silicone plates or silicone tubes), and first rotating shafts 12 are provided at both ends of the conveyor belt 11. By rotating the first rotating shaft 12, the conveyor belt 11 is driven to transport the silicone products.

[0028] The support frame 10 is provided with a first support plate 13, and the support plate is provided with a first vertical plate 14. The driving device 30 includes a driving motor 31 provided on the first vertical plate 14, a driving wheel 32 provided on the output shaft of the driving motor 31, and an internal gear 33 provided on the outer periphery of the driving wheel 32. The axis of the driving wheel 32 is not in a straight line with the axis of the internal gear 33, the diameter of the driving wheel 32 is smaller than the inner diameter of the internal gear 33, and a shifting tooth 34 is provided on the outer periphery of the driving wheel 32. When the shifting tooth 34 is close to the inner circumference of the internal gear 33, the shifting tooth 34 is meshed and connected with the internal gear 33; when the shifting tooth 34 is away from the inner circumference of the internal gear 33, the shifting tooth 34 is separated from the internal gear 33, so that the shifting tooth 34 can periodically shift the internal gear 33.

[0029] Specifically, an inner gear ring and a connecting rod are provided on the inner circumference of the inner gear 33. The output shaft of the driving motor 31 performs uniform circular motion, driving the driving wheel 32 to perform uniform circular motion, thereby driving the shifting tooth 34 to perform uniform circular motion. Since the diameter of the driving wheel 32 is smaller than the inner diameter of the inner gear 33, and the axis of the driving wheel 32 is not in a straight line with the axis of the inner gear 33, the shifting tooth 34 periodically contacts and separates with the inner gear ring of the inner gear 33 in the inner gear 33. When the shifting tooth 34 contacts with the inner gear ring of the inner gear 33, the inner gear 33 is shifted to drive the inner gear 33 to rotate; when the shifting tooth 34 separates from the inner gear ring of the inner gear 33, the inner gear 33 loses the driving wheel and stops rotating, thereby realizing the periodic rotation of the inner gear 33. One end of the connecting rod is fixed on the inner circumference of the inner gear 33, and the other end converges on the rotating shaft of the inner gear 33 and is fixedly connected to the first rotating shaft 12. The inner gear 33 rotates periodically, driving the first rotating shaft 12 to rotate periodically, thereby realizing intermittent movement of the conveyor belt 11, that is, realizing intermittent transmission of silicone products.

[0030] The cutting device 20 includes a mounting frame 22 and a first sliding rod 23 mounted on the supporting frame 10. The mounting frame 22 includes a plurality of first supporting rods 221 disposed on the supporting frame 10 and a second supporting plate 222 disposed on the first supporting rods 221. The first supporting rods 221 are located on both sides of the conveyor belt 11. The second supporting plates 222 are provided with first through holes, and the first sliding rods 23 are slidably connected to the second supporting plates 222 through the first through holes. A moving plate 241 is disposed at one end of the first sliding rod 23 close to the conveyor belt 11, and a knife seat 25 is disposed on the moving plate 241, and a cutting knife 21 is disposed on the knife seat 25. A connecting plate 242 is provided at one end of the first sliding rod 23 away from the conveyor belt 11, and a spring 26 is provided between the connecting plate 242 and the second support plate 222 of the first sliding rod 23. The spring 26 causes the connecting plate 242 to be subjected to an upward elastic force, thereby causing the first sliding rod 23 to move in a direction away from the conveyor belt 11, thereby causing the cutter 21 to move away from the conveyor belt.

[0031] The cutting device 20 further includes a second sliding rod 27. The second support plate 222 is further provided with a second through hole, the connecting plate 242 is provided with a third through hole, and the second sliding rod 27 passes through the second through hole and the third through hole and is connected to the moving plate 241. By pressing the second sliding rod 27 to compress the spring 26, the cutter 21 moves toward the direction of the conveyor belt, thereby cutting the silicone products on the conveyor belt 11. Specifically, the mounting frame 22 further includes a second support rod 223 disposed on the second support plate 222 and a second vertical plate 224 disposed on the second support rod 223. The second vertical plate 224 is rotatably connected with a second rotating shaft 28, and an eccentric block 291 corresponding to the second sliding rod 27 is disposed on the second rotating shaft 28. When the second rotating shaft 28 rotates, the eccentric block 291 periodically presses the second sliding rod 27, so that the cutter 21 periodically cuts the silicone products on the conveyor belt 11. Furthermore, a driving gear 35 is provided on the output shaft of the driving motor 31, and a driven gear 292 is provided on the second rotating shaft 28, and the driving gear 35 is connected to the driven gear 292 via a toothed belt 36. When the output shaft of the driving motor 31 performs uniform circular motion, the driving gear 35 is driven to perform uniform circular motion; the driving gear 35 drives the driven gear 292 to perform uniform circular motion via the toothed belt 36, and then drives the second rotating shaft 28 to perform uniform circular motion, so that the cutter 21 periodically cuts the silicone products on the conveyor belt 11.

[0032] The utility model discloses a silicone product cutting machine capable of intermittent transmission. The specific implementation method is as follows: when cutting silicone products, the silicone products (such as silicone plates or silicone tubes) are continuously transported to the bottom of the cutter 21 through the conveyor belt 11, and the cutter 21 performs reciprocating motion to cut the silicone products into silicone products of a specific length or width. In this process, the output shaft of the driving motor 31 drives the driving wheel 32 to perform uniform circular motion, and the driving wheel 32 drives the internal gear 33 to perform intermittent circular motion, thereby driving the first rotating shaft 12 to perform intermittent circular motion, thereby realizing the intermittent motion of the conveyor belt 11, that is, realizing the intermittent transmission of silicone products. When the cutter 21 contacts the silicone product and the cutter 21 separates from the silicone product during the cutting process, the conveyor belt 11 stops moving, thereby avoiding that the silicone product is subjected to the force of moving forward under the action of the conveyor belt 11 when cutting the silicone product, thereby reducing mechanical wear, improving the cutting accuracy of the silicone product and avoiding deformation of the silicone product cut.

[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
