Description

Technical Field

[0001] This utility model relates to the field of silicone rubber production technology, specifically a cutting device used in the silicone rubber production process. Background Technology

[0002] In the production of silicone rubber, the cutting process is crucial. However, traditional cutting methods face many challenges. Due to its strong flexibility and good elasticity, silicone rubber is widely used in industrial production, medical devices and consumer electronics. However, these characteristics also make it difficult to cut using traditional mechanical methods.

[0003] Traditional cutting methods mainly rely on blades with sharp edges. By applying pressure to the material being cut, the pressure is concentrated at the blade edge. When the pressure exceeds the shear strength of the material, the molecular bonds are broken, thus achieving cutting. However, for soft and elastic materials such as silicone rubber, traditional cutting methods are not very efficient. During the cutting process, silicone rubber is prone to problems such as sticking to the blade, burrs, and uneven edges. This not only affects the processing accuracy of the product, leading to dimensional deviations and poor edge quality, which cannot meet the needs of high-precision applications, but also increases production costs because additional manpower and materials are needed to deal with the problems caused by cutting, while also reducing production efficiency.

[0004] In the existing silicone rubber production process, ultrasonic cutters are mostly used to quickly cut silicone rubber. However, when cutting thicker and larger silicone rubber, conventional cutters cause the silicone rubber to bounce back against the cutter during the cutting process, resulting in unsatisfactory cutting results. Furthermore, most existing ultrasonic cutters cut silicone rubber vertically, which means that larger cutters are needed for the production of thicker and larger silicone rubber. Therefore, a cutting device for silicone rubber production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for use in the production process of silicone rubber, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for use in the production process of silicone rubber, comprising: a transmission frame, a cutting fixing frame fixedly connected to the transmission frame, a movable module fixedly connected to the side of the cutting fixing frame near the transmission frame, a positioning plate connected to the sliding seat of the movable module by bolts, a telescopic cylinder fixedly connected below the positioning plate, and a cutting structure installed at the end of the telescopic rod of the telescopic cylinder;

[0007] The cutting structure includes a cutting blade, which is connected to the end of the telescopic rod of the telescopic cylinder via an ultrasonic structure, and a guide positioning structure is connected to the bottom of the cutting blade;

[0008] Two positioning brackets are fixedly connected to the transmission frame. Two downward pushing cylinders are fixedly connected to the side of the positioning brackets near the transmission frame. An arc-shaped plate is fixedly connected below the downward pushing cylinders. A top pressing structure is connected below the transmission frame. The top pressing structure is used to cooperate with the downward pushing cylinders and the arc-shaped plate to tension the silicone rubber.

[0009] As a further preferred embodiment of this technical solution: the frame of the transmission frame has two placement grooves, the placement grooves are parallel to the cutting blade, and the cutting blade is slidably connected to the inside of the placement grooves.

[0010] As a further preferred embodiment of this technical solution: the guide positioning structure includes two fixing plates, which are respectively fixedly connected to the inside of the placement groove. A guide rod is fixedly connected to the fixing plate, and a support seat is slidably connected to the outside of the guide rod. The support seat has a sliding groove, and a support rod is slidably connected inside the sliding groove. The support rod is fixedly connected to the bottom of the cutting blade.

[0011] As a further preferred embodiment of this technical solution: the ultrasonic structure includes an ultrasonic connector, which is fixedly connected to the end of the telescopic rod of the telescopic cylinder, and the ultrasonic emission of the ultrasonic connector is fixedly connected to the top of the cutting blade.

[0012] As a further preferred embodiment of this technical solution: the top pressing structure includes a lower mounting base, on which two upper top pressing cylinders are fixedly connected. The piston rod end of each upper top pressing cylinder is fixedly connected to a U-shaped rolling seat. A top pressing roller is rotatably connected to the outside of the U-shaped rolling seat. The top pressing roller is located between two positioning and fixing frames.

[0013] As a further preferred embodiment of this technical solution: multiple insertion slots are provided on both sides of the cutting blade, an electromagnet adsorption block is inserted into the inside of the insertion slot, and a replacement blade is fixedly connected to the outside of the electromagnet adsorption block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, after the top pressing structure and the downward pushing cylinder are activated, the arc plate moves down to squeeze and limit the silicone rubber on the transmission roller. At the same time, the top pressing roller in the top pressing structure moves up to press the silicone rubber. The two work together to keep the silicone rubber in a tensioned state. The tensioned state can effectively reduce the rebound phenomenon caused by the elasticity of the silicone rubber, ensuring that the cutting blade can stably and accurately slide and cut the silicone rubber during the lateral movement. This avoids the cutting deviation caused by the rebound of silicone rubber in the traditional cutting method and improves the flatness and accuracy of the cutting edge.

[0016] 2. In this utility model, when cutting large and thick silicone rubber laterally, an ultrasonic connector is used to transmit ultrasonic vibrations to the cutting blade to form ultrasonic cutting. The energy of the ultrasonic waves is used to assist the cutting process, making the cutting process smoother, reducing cutting resistance, and reducing the probability of cutting misalignment. This improves the overall cutting effect and reduces cutting misalignment during the lateral cutting process. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1-6 This utility model provides a technical solution: a cutting device for the production process of silicone rubber, comprising: a transmission frame 1, a cutting fixing frame 2 fixedly connected to the transmission frame 1, a moving module 3 fixedly connected to the side of the cutting fixing frame 2 near the transmission frame 1, a positioning plate 4 bolted to the sliding seat of the moving module 3, a telescopic cylinder 6 fixedly connected below the positioning plate 4, and a cutting structure installed at the end of the telescopic rod of the telescopic cylinder 6.

[0027] The cutting structure includes a cutting blade 8, which is connected to the end of the telescopic rod of the telescopic cylinder 6 via an ultrasonic structure. A guide positioning structure is connected to the bottom of the cutting blade 8.

[0028] Two positioning brackets 13 are fixedly connected to the transmission frame 1. Two downward pushing cylinders 14 are fixedly connected to the side of the positioning brackets 13 near the transmission frame 1. An arc-shaped plate 15 is fixedly connected below the downward pushing cylinders 14. A top pressing structure is connected below the transmission frame 1. The top pressing structure is used to cooperate with the downward pushing cylinders 14 and the arc-shaped plate 15 to tension the silicone rubber.

[0029] In this embodiment, specifically: during use, the transmission frame 1 is connected to the outlet of the silicone rubber production discharge machine. After the silicone rubber discharge machine discharges, it flows onto the transmission frame 1. As the transmission rollers on the transmission frame 1 rotate, the silicone rubber is transported. After the silicone rubber is transported to below the cutting and fixing frame 2, a laser positioner is used to locate the position where the silicone rubber needs to be cut. After the position where the cutting needs to be done is located, the top pressure structure and the lower push cylinder 14 are activated. After the lower push cylinder 14 is activated, it can drive the arc plate 15 to move downward. Then, the silicone rubber on the transmission roller can be squeezed and limited. After squeezing and limiting, the top pressure structure will further squeeze the silicone rubber from below, thereby tensioning the silicone rubber. After the silicone rubber is tensioned, the moving module 3 can be started to drive the positioning plate 4, telescopic cylinder 6 and cutting blade 8 to move laterally. First, a cutting opening is cut on one side of the silicone rubber, and then cutting is carried out along the cutting opening. During the lateral movement of the cutting blade 8, the tensioned silicone rubber can be slid-cut, resulting in a faster overall cutting speed. After tensioning, the phenomenon of silicone rubber rebounding from the blade can also be reduced.

[0030] like Figure 2As shown, two placement grooves 5 are provided on the frame of the transmission frame 1. The placement grooves 5 are parallel to the cutting blade 8, and the cutting blade 8 is slidably connected inside the placement grooves 5.

[0031] In this embodiment, specifically: when not cutting, the cutting blade 8 is stored inside the placement grooves 5 on both sides of the frame to avoid affecting the transmission of the silicone rubber.

[0032] As shown in the figure - Figure 3 As shown, the guide positioning structure includes two fixing plates 9, which are fixedly connected to the inside of the placement groove 5. A guide rod 10 is fixedly connected to the fixing plate 9. A support seat 11 is slidably connected to the outside of the guide rod 10. The support seat 11 has a sliding groove. A support rod 12 is slidably connected inside the sliding groove. The support rod 12 is fixedly connected to the bottom of the cutting blade 8.

[0033] In this embodiment, specifically: during the movement of the cutting blade 8, relying solely on the telescopic cylinder 6 to fix the cutting blade 8 would only fix the upper part, while the lower part of the cutting blade 8 is connected to the support base 11 via the support rod 12. The support base 11 is located outside the guide rod 10. When the cutting blade 8 slides laterally to cut the rubber, the lower support base 11 can cooperate with the guide rod 10 to guide the cutting blade 8.

[0034] like Figures 1-4 As shown, the top pressing structure includes a lower mounting base 16, on which two upper top pressing cylinders 17 are fixedly connected. The piston rod end of the upper top pressing cylinder 17 is fixedly connected to a U-shaped rolling seat 18. The outside of the U-shaped rolling seat 18 is rotatably connected to a top pressing roller 19, which is located between two positioning and fixing frames 13.

[0035] In this embodiment, specifically: in the top-pressing structure, by activating the upper top-pressing cylinder 17, the U-shaped rolling seat 18 and the top-pressing roller 19 can be moved upward. When the upper top-pressing cylinder 17 moves the U-shaped rolling seat 18 and the top-pressing roller 19 upward, the silicone rubber located on the top-pressing roller 19 can be pressed. After the curved plate 15 fixes the two sides of the silicone rubber, the top-pressing roller 19 can press the silicone rubber to form a certain tension, reducing the phenomenon of silicone rubber rebounding from the cutting tool during the cutting process.

[0036] Example 2

[0037] Considering that during use, when cutting large and thick silicone rubber, the cutting speed is slow when using a single blade, and the lateral movement force of the moving module 3 to drive the cutting blade 8 is insufficient during transverse cutting, an ultrasonic structure is added to solve the above technical problems, specifically:

[0038] like Figures 1-3As shown, the ultrasonic structure includes an ultrasonic connector 7, which is fixedly connected to the end of the telescopic rod of the telescopic cylinder 6, and the ultrasonic emission of the ultrasonic connector 7 is fixedly connected to the top of the cutting blade 8.

[0039] In this embodiment, specifically: when cutting larger and thicker silicone rubber, the ultrasonic connector 7 can be activated to transmit the ultrasonic vibration generated by the ultrasonic generator to the outside of the cutting blade 8. The cutting blade 8 and the ultrasonic connector 7 together form an ultrasonic cutting mechanism. At this time, it is easier to make transverse cuts on larger and thicker silicone rubber. Furthermore, the cutting blade 8 moves laterally, which further reduces the phenomenon of cutting misaligned layers. During the slow cutting process, the cutting blade 8 can also be moved up and down by the telescopic cylinder 6, so that the cutting blade 8 forms a sawing state for cutting larger and thicker silicone rubber. In addition, the cutting blade 8 can be disconnected from the support rod 12 below and tilted, so that when cutting larger and thicker silicone rubber, only a portion of the thickness is cut each time, forming a parallel tilted sliding cut back and forth.

[0040] like Figure 6 As shown, multiple insertion slots 803 are provided on both sides of the cutting blade 8. An electromagnet adsorption block 802 is inserted into the insertion slot 803, and a replacement blade 801 is fixedly connected to the outside of the electromagnet adsorption block 802.

[0041] In this embodiment, specifically: during the use of the cutting blade 8, replacement blades 801 can be magnetically connected to both sides of the cutting edge of the cutting blade 8, so that the replacement blades 801 are inserted into the insertion slot 803 through the electromagnet adsorption block 802, forming a replaceable side blade, which makes it convenient to directly replace the replacement blades 801 when the cutting edge of the cutting blade 8 is worn.

[0042] Working principle: During use, the transmission frame 1 is connected to the outlet of the silicone rubber production discharge machine. After the silicone rubber is discharged, it flows onto the transmission frame 1, and is driven by the rotation of the transmission rollers on the transmission frame 1. When the silicone rubber is driven to the bottom of the cutting and fixing frame 2, the laser positioner is used to locate the position where the silicone rubber needs to be cut.

[0043] After positioning, the top pressing structure and the lower pushing cylinder 14 are activated. The lower pushing cylinder 14 drives the arc plate 15 to move downward, squeezing and limiting the silicone rubber on the transmission roller. At the same time, the upper pressing cylinder 17 in the top pressing structure is activated, driving the U-shaped rolling seat 18 and the top pressing roller 19 to move upward, pressing the silicone rubber. It works with the arc plate 15 to tension the silicone rubber, reducing the phenomenon of silicone rubber rebounding from the cutting tool during the cutting process. After the silicone rubber is tensioned, the moving module 3 is activated, driving the positioning plate 4, the telescopic cylinder 6 and the cutting blade 8 to move laterally. During the movement of the cutting blade 8, its bottom is connected to the support seat 11 through the support rod 12. The support seat 11 is slidably connected to the outside of the guide rod 10. The guide rod 10 is fixed on the fixed plate 9. The fixed plate 9 is located in the placement groove 5 of the transmission frame 1. The placement groove 5 is parallel to the cutting blade 8. In this way, the support seat 11 and the guide rod 10 can guide the cutting blade 8, ensuring the stability of the lateral movement of the cutting blade 8.

[0044] The cutting blade 8 first makes a cutting opening on one side of the silicone rubber, and then slides along the cutting opening to make a faster overall cutting speed. When cutting larger and thicker silicone rubber, the ultrasonic connector 7 is activated to transmit the ultrasonic vibration generated by the ultrasonic generator to the outside of the cutting blade 8, so that the cutting blade 8 and the ultrasonic connector 7 together form an ultrasonic cutting blade. At this time, it is easier to make transverse cuts on larger and thicker silicone rubber, and the transverse movement of the cutting blade 8 can reduce the phenomenon of cutting misalignment.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
