Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, and particularly to a cutting device applied to a heating plate. Background Technique

[0002] With the development of industrial technology, especially in some industries that require customized heating solutions, such as plastic processing, medical equipment, laboratory equipment, etc., the demand for heating technologies that can adapt to complex shapes and require rapid response is increasing. However, due to its metal structure, traditional metal heating plates are difficult to deform, resulting in limitations in their applications. Therefore, silicone rubber heating plates with elastic silicone rubber plates as carriers have been developed as a new heating technology with better adaptability and efficiency.

[0003] Silicone rubber heating plates are made of materials such as silicone rubber, metal, and electronic components that are not easily degradable. If not properly handled, they are likely to cause environmental pollution. Therefore, it is necessary to uniformly recycle scrapped or aged silicone rubber heating plates. To facilitate the separation of metals and electronic components such as resistance wires in the silicone rubber heating plate from two pressed silicone rubber plates, the silicone rubber heating plate is usually cut. However, due to the sticky and slippery surface of the silicone rubber plate, it is difficult to be pushed on the cutting platform, resulting in the need for workers to move it to the cutting position by pulling, making the position of the workers very close to the working position of the cutting knife, prone to safety accidents, and the conveying efficiency is also not high. Summary of the Utility Model

[0004] The utility model provides a cutting device applied to a heating plate, which solves the problem of easy occurrence of safety accidents in the cutting work of the heating plate in the related art.

[0005] The technical solution of the utility model is as follows:

[0006] A cutting device applied to a heating plate includes a cutting mechanism. The cutting mechanism includes a cutting seat, a cutting frame, and a cutting knife. The cutting frame is fixedly connected to the cutting seat, and the cutting knife is slidably connected to the cutting frame. The cutting seat has a plurality of conveying components, and each of the conveying components is symmetrically and evenly distributed around the cutting seat; each of the conveying components includes a transmission chain, a driving motor, a driving wheel, a driven wheel, and a plurality of clamping bodies.

[0007] Further, the cutting base is provided with a plurality of guide rails, each of the guide rails corresponds to each conveying component one by one, and each of the clamping bodies is slidably connected to the guide rail.

[0008] Further, the clamping body includes a connecting seat, a clamping plate, and a driving lead screw for driving the clamping plate to clamp the heating plate. The connecting seat is fixedly connected to the transmission chain and is slidably connected to the guide rail, and the driving lead screw is rotatably connected to the connecting seat.

[0009] Further, the connecting seat is provided with a plurality of rollers, each of the rollers is rotatably connected to the connecting seat and is symmetrically distributed on the connecting seat with the guide rail as the center. Both sides of the guide rail are provided with rolling grooves, and each of the rollers is located in the corresponding rolling groove.

[0010] Further, the cutting base has an installation platform, and the horizontal height of the clamping body is higher than the highest horizontal height of the installation platform.

[0011] Further, there are two clamping plates, the driving lead screw is a double-headed lead screw, and each of the clamping plates is symmetrically distributed at both ends of the driving lead screw with the driving lead screw as the center. The horizontal height of the lowest point of each clamping plate is higher than the highest point of the installation platform.

[0012] Further, baffles are provided on both sides of the installation platform, and each of the baffles is located at one end of the installation platform away from the cutting knife.

[0013] Further, a synchronizing shaft is provided between adjacent driven wheels, and both ends of the synchronizing shaft are fixedly connected to the end faces of adjacent driven wheels.

[0014] The working principle and beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the cutting mechanism completes the cutting work of the heating plate by sliding the cutting knife on the cutting frame. The cutting frame is fixedly arranged on the cutting base, and the cutting base has a plurality of conveying components, and each of the conveying components is symmetrically and evenly distributed with the cutting base as the center, ensuring that the conveying force of the present utility model can act on the heating plate evenly, sending the heating plate into the cutting area of the cutting knife for cutting work;

This transmission structure does not move the heating plate itself, but moves with the heating plate, which fundamentally avoids the problem of high friction when the heating plate moves; and the heating plate is driven to move by a mechanical transmission structure, which is safer than manual pulling and reduces the probability of safety accidents.

[0017] 2. The cutting seat in the utility model is provided with a cutting platform, which is fixedly connected to the cutting seat, so that when the cutting knife descends to the corresponding position, it will cooperate with the cutting platform, so that the cutting platform limits the heating plate to prevent the heating plate from being deformed when it is subjected to the force from the cutting knife, thereby affecting the normal cutting effect of the cutting knife and ensuring the cutting efficiency; and, by controlling the installation position of the clamping body on the transmission chain, when the clamping body sends the heating plate to the cutting position of the cutting knife, the clamping bodies in each conveying assembly can be located on both sides of the cutting knife to prevent the cutting knife from contacting the clamping body and preventing interference between the clamping body and the cutting knife.

[0029] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0030] As Figure 1 , Figures 3 to 6 shown, this embodiment proposes a cutting device applied to a heating plate, mainly including a cutting mechanism 1. The cutting mechanism 1 includes a cutting base 11, a cutting frame 12, and a cutting knife 13. The cutting frame 12 is fixedly connected to the cutting base 11, and the cutting frame 12 has a driving assembly for driving the cutting knife 13 to perform cutting; the driving assembly includes a rotating shaft and a rotating motor, the rotating shaft is linked with the output shaft of the rotating motor, a rotating eccentric wheel is provided on the rotating shaft, and the cutting knife 13 is linked with the rotating eccentric wheel; and the cutting knife 13 is slidably connected to the cutting frame 12, and the limit constraint of the cutting knife 13 on the cutting frame 12 is realized by means of the sliding connection between the cutting knife 13 and the cutting frame 12, so that the cutting knife 13 can only move up and down under the driving action of the driving assembly, and will not move left and right, so that the cutting knife 13 can perform reciprocating lifting movement on the cutting frame 12 under the action of the rotating eccentric wheel to complete the cutting work on the heating plate.

[0031] The cutting base 11 is provided with a plurality of conveying assemblies 2, that is, in this embodiment, a mechanical conveying method is adopted to send the heating plate to the cutting position of the cutting knife 13. Compared with pulling the heating plate into the cutting position of the cutting knife 13 by manpower, it is safer and greatly avoids safety accidents in the cutting work of the heating plate.

[0032] Specifically, each conveying component 2 includes a transmission chain 21, a driving motor 22, a driving wheel 23, a driven wheel 24, and a number of clamping bodies 25. The driving wheel 23 is linked to the output shaft of the driving motor 22. Both the driven wheel 24 and the driving wheel 23 are rotatably connected to the cutting seat 11. The transmission chain 21 links the driving wheel 23 and the driven wheel 24. Each clamping body 25 is fixedly connected to the transmission chain 21. That is, each clamping body 25 holding the heating plate will move along with the transmission chain 21 under the rotation of the driving wheel 23, and this movement is repeated cyclically along the circular structure track formed by the transmission chain 21, which is convenient for arranging workers to install or disassemble the heating plate at a certain position of the conveying component 2 for assembly line work and improve the cutting efficiency.

[0033] Moreover, this conveying method does not move the heating plate itself, but drives the heating plate to move by controlling the movement of the carrier of the heating plate, fundamentally avoiding the problem of large friction when the heating plate moves. At the same time, each conveying component 2 is symmetrically and evenly distributed around the cutting seat 11, so that the conveying force in this embodiment can act evenly on the heating plate to ensure the conveying effect. And each clamping body 25 is located between adjacent conveying components 2, that is, both sides of the heating plate can be clamped by the clamping body 25 to ensure the stability of the heating plate during the conveying and cutting processes.

[0034] Furthermore, considering that the silicone rubber heating plate will deform to relieve pressure due to the elastic characteristics of the silicone rubber plate when bearing the pressure (cutting force) from the cutting knife 13, the cutting seat 11 has a cutting platform 111 for cooperating with the cutting knife 13. The cutting platform 111 is fixedly connected to the cutting seat 11, so that the heating plate between the cutting knife 13 and the cutting platform 111 cannot deform due to the block of the cutting platform 111 during deformation, and thus can be smoothly cut off by the cutting knife 13 to ensure the cutting efficiency of this embodiment. At the same time, the adjacent clamping bodies 25 between the cutting platform 111 and the cutting knife 13 are symmetrically and evenly distributed around the cutting knife 13. That is, the installation position of each clamping body 25 on the transmission chain 21 should be controlled so that when the clamping body 25 brings the heating plate into the cutting position of the cutting knife 13, it can be located on both sides of the cutting knife 13, rather than directly below the cutting knife 13, to prevent the cutting knife 13 from interfering with the clamping body 25 and causing phenomena such as structural damage in this embodiment that affect the normal use of this embodiment.

[0035] As Figures 2 to 4 shown, the cutting seat 11 in this embodiment is provided with a number of guide rails 26. Each guide rail 26 corresponds to each conveying component 2 one by one. Each clamping body 25 is slidably connected to the guide rail 26. After each clamping body 25 is slidably connected to the guide rail 26, the position of the clamping body 25 can be restricted by the guide rail 26, and at the same time, the transmission chain 21 can be restricted to prevent the transmission chain 21 from swinging during transmission, improving the stability and reliability of the conveying component 2.

[0036] like Figures 7 to 8 As shown, the clamping body 25 in this embodiment includes a connecting seat 251, a clamping plate 252, and a driving screw 253 for driving the clamping plate 252 to clamp the heating plate. The connecting seat 251 is fixedly connected to the transmission chain 21 and is slidably connected to the guide rail 26. The driving screw 253 is rotatably connected to the connecting seat 251, and the clamping plate 252 is threadedly connected to the driving screw 253. That is, when it is necessary to clamp the heating plate, the clamping plate 252 can be driven to move by rotating the driving screw 253, so as to clamp the heating plate. The screw transmission structure is selected as the clamping structure of the heating plate. While ensuring the clamping efficiency, it also has a certain self-locking property, which effectively ensures the stability of the structure after the clamping body 25 clamps the heating plate.

[0037] like Figures 5 to 6 , Figure 8 As shown, the connecting seat 251 in this embodiment is provided with a plurality of rollers 254, each of which is rotatably connected to the connecting seat 251 and is symmetrically distributed on the connecting seat 251 with the guide rail 26 as the center. Rolling grooves 261 are provided on both sides of the guide rail 26, and each roller 254 is located in the rolling groove 261 corresponding thereto, that is, the sliding connection between the clamping body 25 and the guide rail 26 in this embodiment adopts the sliding structure of the roller 254, which effectively reduces the friction between the clamping body 25 and the guide rail 26 when the clamping body 25 moves under the action of the transmission chain 21, so that the sliding of the clamping body 25 is lighter and more labor-saving, and the smoothness of the sliding of the clamping body 25 is ensured; and through the mutual cooperation of the rollers 254 and the rolling grooves 261, the axial displacement of the clamping body 25 on the driving wheel 23 can be constrained, so as to prevent the clamping body 25 from being separated from the guide rail 26 due to the vibration of the equipment, and ensure the integrity of the overall structure of this embodiment.

[0038] like Figures 4 to 6 As shown, the cutting seat 11 in this embodiment has a mounting platform 112, and the horizontal height of the clamping body 25 is higher than the highest horizontal height of the mounting platform 112, that is, when the heating plate is installed on the clamping body 25, the mounting platform 112 can be used to make the heating plate be on a certain plane, and then a part of the heating plate is lifted up and clamped on the clamping body 25, which facilitates the clamping work of the heating plate and avoids the heating plate from sliding or falling due to the influence of gravity due to the lack of support at the bottom, affecting the normal clamping work of the heating plate and indirectly interfering with the cutting efficiency of the heating plate.

[0039] In this embodiment, there are two clamping plates 252. The driving lead screw 253 is a double-headed lead screw. Each clamping plate 252 is symmetrically distributed at both ends of the driving lead screw 253 with the driving lead screw 253 as the center. That is, by rotating the driving lead screw 253, the two clamping plates 252 can be simultaneously driven to move in opposite directions. With this synchronous movement characteristic, each clamping plate 252 can not only play the role of clamping the heating plate, but also play a role in lifting the heating plate to a certain extent, so that the heating plate automatically disengages from the installation platform 112, facilitating the installation work of the heating plate. When the installation work of the heating plate is completed, the horizontal height of the lowest point of each clamping plate 252 is higher than the horizontal height of the highest point of the installation platform 112, which not only avoids the problem of large friction of the heating plate, but also prevents the clamping plate 252 from interfering with the installation platform 112, ensuring the stability and safety of the operation of this embodiment.

[0040] As Figure 3 , Figures 5 to 6 shown, baffles 4 are provided on both sides of the installation platform 112 in this embodiment. Each baffle 4 is located at one end of the installation platform 112 away from the cutting knife 13. That is, with the cooperation of the two baffles 4 and the installation platform 112, an operation station is formed. Each baffle 4 plays a role in preventing the staff from contacting the transmission chain 21, improving the safety of this embodiment.

[0041] As Figures 2 to 3 shown, there is a synchronizing shaft 3 between adjacent driven wheels 24 in this embodiment. Both ends of the synchronizing shaft 3 are fixedly connected to the end faces of adjacent driven wheels 24 respectively. That is, with the synchronizing shaft 3, the adjacent driven wheels 24 can have a linkage relationship, enabling each conveying component 2 to only need to retain one driving motor 22 to achieve synchronous conveying work between each conveying component 2. Thus, there is no need to design a complex control program to control each driving motor 22 to run synchronously, reducing the operation cost of this embodiment; and, to prevent the synchronizing shaft 3 from interfering with the installation platform 112, the installation platform 112 should be located between adjacent driving wheels 23.

[0042] In this embodiment, the rotating motor and the driving motor 22 are both preferably servo motors because the servo motor can achieve highly precise position, speed, and acceleration control through a feedback mechanism, facilitating the implementation of the intermittent movement of each clamping body 25 so that the cutting mechanism 1 can cut the heating plate. For example, when the cutting knife 13 moves to the highest point under the action of the eccentric wheel, the driving motor 22 starts to drive each clamping body 25 to move, thus avoiding interference between the conveying component 2 and the cutting mechanism 1 during the working process and ensuring the stability and safety of the operation of this embodiment.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
