Description

Technical Field

[0001] This invention relates to the field of industrial production technology, specifically to a pressure-balanced hobbing cutter. Background Technology

[0002] A pressure-balanced roller cutter is a mechanical device used for cutting, pressing, and processing materials. It typically consists of a rotating roller and a corresponding pressure block. By applying appropriate pressure and rotational force, the pressure-balanced roller cutter can perform cutting operations efficiently and maintain stable cutting quality when processing different types of materials. It is used for automatic cutting or pressing operations on production lines. Due to its efficiency and reliability, the pressure-balanced roller cutter is widely used in industrial production. Currently, existing pressure-balanced hobs accumulate a large amount of heat in their internal cavities during prolonged continuous operation, generating pressure that causes the hob to overheat. This leads to material degradation of the hob and its components, reducing their performance, cutting effect, and cutting quality, as well as wear on the fixtures. It also causes the surrounding environment to heat up, posing certain safety risks and requiring shutdown for cooling. However, these methods cannot guarantee the standardization of internal pressure during operation and cannot release pressure when it becomes too high to reduce the hob temperature, which has certain shortcomings. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a pressure-balanced hob, which has the advantages of automatically releasing pressure, reducing the temperature and pressure inside the hob cavity during operation, keeping it at standard temperature and pressure values, reducing the hob damage rate, and improving production efficiency. It solves the problems of the current stage where the hob needs to be stopped to cool down when it overheats during continuous operation, which is cumbersome to operate and has low production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pressure-balanced roller cutter, comprising a roller cutter assembly and a release assembly. The roller cutter assembly includes a roller cutter body, in which a hollow cavity is formed. A partition plate is fixed inside the hollow cavity, and a connecting button is fixed on the partition plate. A connecting rod is threaded onto the connecting button. The roller cutter body is used to cut materials, and the hollow cavity inside provides storage space for the generated pressurized gas. The partition plate is fixed at the center of the roller cutter body, thus forming two hollow cavities inside. Each hollow cavity is movably fitted with an exhaust pipe. When internal pressure is generated, the exhaust pipe is pushed outward, thereby releasing excess pressurized gas.

[0005] The release assembly includes an exhaust cylinder movably fitted inside a hollow cavity. A stabilizing sleeve hole is provided at one end of the exhaust cylinder, and a connecting rod is movably fitted inside the stabilizing sleeve hole. The side of the exhaust cylinder matches the diameter inside the hollow cavity, which improves the sealing performance and allows the exhaust cylinder to move smoothly in and out. The connecting rod is used to connect with the drive assembly to drive the entire device to rotate. During the rotation, the roller cutter body applies pressure to cut the material.

[0006] When the pressure-balancing roller needs to release internal pressure during installation and operation, exhaust pipes are movably fitted into the hollow cavities at both ends of the roller body, ensuring that the stabilizing sleeve is movably fitted into the side of the stabilizing sleeve rod. Simultaneously, both ends of the spring rod are fixed to the side of the partition plate and one end of the stabilizing sleeve. The limit button fixed on the connecting rod is connected to the fixed seat on the output end of the drive assembly. The drive assembly operates, causing its output end to rotate the fixed seat, thus rotating the pressure-balancing roller to cut the material. During prolonged operation, pressure builds up inside the hollow cavity. When the pressure exceeds the tension of the spring rod, the exhaust pipe moves outward from the hollow cavity, allowing the pressure to be discharged from the exhaust groove. Once the pressure inside the hollow cavity reaches the normal standard pressure, the exhaust pipe returns to its initial position under the pulling force of the spring rod, ready to be released again when the pressure exceeds the standard pressure in subsequent operations.

[0007] As a further improvement to the above solution, a stabilizing protrusion is fixed in the hollow cavity along its length, and a stabilizing groove is opened on the side of the exhaust pipe along its length, with the stabilizing protrusion slidably connected in the stabilizing groove.

[0008] With the above technical solution, when the exhaust pipe moves in and out of the hollow cavity, the stabilizing groove slides on the side of the stabilizing protrusion, increasing the stability of the exhaust pipe movement.

[0009] As a further improvement to the above solution, a limit button is fixed to one end of the connecting rod.

[0010] Through the above technical solution, the diameter of the limit button is larger than that of the stabilizing sleeve hole, which can limit the distance that the exhaust pipe moves outward and prevent the exhaust pipe from leaving the hollow cavity.

[0011] As a further improvement to the above solution, the partition plate is provided with an air supply groove that communicates with the hollow cavity.

[0012] Through the above technical solution, air is supplied between the two hollow cavities via an air supply channel, thereby improving the pressure uniformity within the two cavities.

[0013] As a further improvement to the above solution, a stabilizing sleeve is fixed on the partition plate, and a stabilizing sleeve is fixed inside the exhaust pipe, with the stabilizing sleeve movably sleeved on the stabilizing sleeve.

[0014] Through the above technical solution, when the exhaust pipe moves telescopically, the stabilizing sleeve moves to the side of the stabilizing sleeve rod, which improves the stability of the exhaust pipe under internal pressure impact and avoids tilting to one side, thus preventing jamming.

[0015] As a further improvement to the above solution, a spring rod is fixed to one end of the stabilizing sleeve, the spring rod is movably sleeved on the side of the stabilizing sleeve rod, and one end is fixed to the partition plate.

[0016] Through the above technical solution, the spring rod has a pulling force, which pulls the stabilizing sleeve to move to the tail end of the stabilizing sleeve rod, so that the exhaust pipe is completely inserted into the hollow cavity. After pressure is formed in the hollow cavity, and the pressure is greater than the tension of the spring rod, the spring rod is pulled open, and the exhaust pipe moves outward from the hollow cavity.

[0017] As a further improvement to the above solution, a limiting ring is fixed at one end of the exhaust pipe, and a limiting groove is opened at the interface of the hollow cavity, with the limiting ring fitting inside the limiting groove.

[0018] Through the above technical solution, the limiting ring is made of rubber and is used to limit the depth of the exhaust pipe moving into the hollow cavity, reduce the impact force when the exhaust pipe moves into the hollow cavity after the pressure is released, and at the same time, the side fits into the inner side of the limiting groove to improve the sealing of the interface and avoid air leakage when the internal pressure is at the standard value.

[0019] As a further improvement to the above solution, the side of the exhaust pipe is provided with multiple exhaust grooves, and the width of the exhaust grooves gradually increases in sequence.

[0020] With the above technical solution, the side of the exhaust pipe has multiple exhaust grooves equidistantly opened from the front end to the rear end, and the width of the exhaust grooves gradually increases from the front end to the rear end. When the pressure inside the cavity exceeds the standard pressure, the exhaust pipe is pushed according to the magnitude of the excess pressure, so that the exhaust groove that matches the excess pressure value is removed and releases air at the same time as the front exhaust groove, thereby achieving rapid air release and enabling the internal pressure to be quickly balanced.

[0021] Compared with the prior art, the present invention provides a pressure-balanced hob, which has the following beneficial effects: 1. This pressure-balanced roller cutter features two hollow cavities separated by a partition plate within the cutter body. A gas channel connects the two cavities, allowing pressure to be balanced. An exhaust pipe is movably fitted inside each hollow cavity, while a stabilizing rod is fixed within the cavity. A stabilizing sleeve is fixed inside the exhaust pipe, movably fitted onto the side of the stabilizing rod. When the pressure within the cavity exceeds the standard pressure value, the pressure pushes the exhaust pipe outward from the hollow cavity, allowing gas to escape through the side exhaust channel. Under the tension of an internal spring rod, the exhaust pipe automatically resets, achieving autonomous pressure and temperature release, effectively improving production efficiency and extending the roller cutter's service life.

[0022] 2. This pressure-balanced roller cutter features a spring rod movably connected to the side of a stabilizing sleeve. Both ends of the spring rod are fixed to one end of the stabilizing sleeve and a partition plate. Under the tension of the spring rod, when the cavity is at the standard pressure value, the exhaust pipe is fully fitted inside the hollow cavity. When the internal pressure exceeds the standard pressure value, the pressure pushes the exhaust pipe, causing it to extend and allowing the pressure to be discharged through the exhaust groove on the side of the exhaust pipe. When the internal pressure returns to the standard value, the exhaust pipe automatically resets under the tension of the spring rod. This achieves automatic temperature and pressure release based on the roller cutter's own temperature and pressure during operation. The excess pressure beyond the standard value pushes the exhaust pipe, causing the wider exhaust groove to leak out for venting, thus enabling rapid pressure and temperature release and further improving production efficiency and the service life of the roller cutter.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0026] Please see Figure 1-4 As shown, the pressure-balanced roller cutter proposed in this embodiment includes a roller cutter assembly 1 and a release assembly 2. The roller cutter assembly 1 includes a roller cutter body 101, a hollow cavity 102 is formed inside the roller cutter body 101, a partition plate 104 is fixed inside the hollow cavity 102, a connecting button 105 is fixed on the partition plate 104, and a connecting rod 106 is threadedly connected to the connecting button 105. The roller cutter body 101 is used to cut materials, and the hollow cavity 102 inside is used to provide storage space for the generated pressurized gas. The partition plate 104 is fixed at the center position inside the roller cutter body 101, thereby forming two hollow cavities 102 inside, and each of the two hollow cavities 102 is movably sleeved with a discharge valve. When air pressure is generated inside the air cylinder 201, it pushes the exhaust cylinder 201 outward to release excess gas. The release component 2 includes the exhaust cylinder 201 movably fitted inside the hollow cavity 102. One end of the exhaust cylinder 201 has a stabilizing sleeve hole 203. The connecting rod 106 is movably fitted inside the stabilizing sleeve hole 203. The side of the exhaust cylinder 201 matches the diameter inside the hollow cavity 102, which improves the sealing performance and allows the exhaust cylinder 201 to move smoothly. The connecting rod 106 is used to connect with the drive component to drive the entire device to rotate. During the rotation, the roller cutter body 101 applies pressure to cut the material.

[0027] The working principle of the pressure-balanced roller cutter proposed in this embodiment is as follows: During use, exhaust pipes 201 are movably sleeved in the hollow cavities 102 at both ends of the roller cutter body 101, ensuring that the stabilizing sleeve 205 is movably sleeved on the side of the stabilizing rod 109. At the same time, both ends of the spring rod 206 are fixed to the side of the partition plate 104 and one end of the stabilizing sleeve 205. Then, by connecting the limit button 107 fixed on the connecting rod 106 to the fixed seat on the output end of the drive component, the drive component operates, causing its output end to drive the fixed seat to rotate, thereby causing the pressure-balanced roller cutter to rotate and cut the material. Under long-term operation, pressure is formed in the hollow cavity 102. When the pressure is greater than the tension of the spring rod 206 (spring rod 209), the pressure increases. The tension of spring rod 206 is matched with the pressure inside hollow cavity 102. When the pressure reaches its maximum, spring rod 206 can be fully stretched. When the pressure meets the minimum tension of spring rod 206, the exhaust pipe 201 moves slowly outward. As the exhaust pipe 201 moves outward from hollow cavity 102, the pressure is discharged from the exhaust groove 207 until the pressure inside hollow cavity 102 is at the normal standard pressure. Then, under the pulling force of spring rod 206, the exhaust pipe 201 returns to its initial position (the side of the exhaust pipe 201 is completely inserted into hollow cavity 102, so that the exhaust groove 207 fits against the inner wall of hollow cavity 102, sealing the groove). In subsequent operations, if the pressure exceeds the standard pressure, it can be released again. Example

[0028] Please see Figure 1-4 As shown, the pressure balancing cutter proposed in this embodiment, based on Embodiment 1, further includes, in addition to, a stabilizing protrusion 103 fixed along the length of the hollow cavity 102, and a stabilizing groove 202 formed along the length of the side of the exhaust pipe 201. The stabilizing protrusion 103 is slidably connected within the stabilizing groove 202. One end of the connecting rod 106 is fixed with a limit button 107. An air delivery groove 108 communicating with the hollow cavity 102 is formed on the partition plate 104. A stabilizing sleeve rod 109 is fixed on the partition plate 104. Meanwhile, the exhaust pipe 201 is fixed with... A stabilizing sleeve 205 is fixedly fitted onto a stabilizing rod 109. A spring rod 206 is fixed to one end of the stabilizing sleeve 205. The spring rod 206 is movably fitted onto the side of the stabilizing rod 109 and one end is fixed to the partition plate 104. A limiting ring 208 is fixed to one end of the exhaust pipe 201. At the same time, a limiting groove 1021 is opened at the interface of the hollow cavity 102. The limiting ring 208 fits into the limiting groove 1021. Multiple exhaust grooves 207 are opened on the side of the exhaust pipe 201, and the width of the exhaust grooves 207 gradually increases.

[0029] In this design, when the exhaust pipe 201 extends and retracts within the hollow cavity 102, the stabilizing groove 202 slides on the side of the stabilizing protrusion 103, increasing the stability of the exhaust pipe 201's movement. The diameter of the limiting button 107 is larger than that of the stabilizing sleeve hole 203, thus limiting the outward movement distance of the exhaust pipe 201 and preventing it from detaching from the hollow cavity 102. Air is supplied between the two hollow cavities 102 via the air supply groove 108, improving the pressure uniformity within the two cavities. During the extension and retraction of the exhaust pipe 201, the stabilizing sleeve 205 moves on the side of the stabilizing sleeve rod 109, improving the stability of the exhaust pipe 201 under internal pressure impact and preventing it from tilting to one side and causing jamming. The spring rod 206 provides tension, pulling the stabilizing sleeve 205 towards the tail end of the stabilizing sleeve rod 109, allowing the exhaust pipe 201 to fully enter the hollow cavity 102. After pressure is formed within the hollow cavity 102, and the pressure... When the tension is greater than that of the spring rod 206, the spring rod 206 is pulled open. At this time, the exhaust pipe 201 moves outward from the hollow cavity 102. The limiting ring 208 is made of rubber and is used to limit the depth of the exhaust pipe 201 moving into the hollow cavity 102, reducing the impact force when the exhaust pipe 201 moves into the hollow cavity 102 after pressure release. At the same time, the side fits against the inner side of the limiting groove 1021, improving the sealing of the interface and preventing air leakage when the internal pressure is at the standard value. The side of the exhaust pipe 201 has multiple exhaust grooves 207 evenly spaced from the front end to the rear end, and the width of the exhaust grooves 207 from the front end to the rear end increases. When the pressure in the cavity exceeds the standard pressure, the exhaust pipe 201 is pushed according to the magnitude of the excess pressure, so that the exhaust groove 207 that matches the excess pressure value is removed and the exhaust is released at the same time as the front exhaust groove 207, thereby achieving rapid air release and allowing the internal pressure to be quickly balanced.

[0030] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
