[0002] A rubber ring cutting machine is a machine used to cut rubber materials into rubber rings of specific shapes. It is widely used in rubber product manufacturing, machinery manufacturing, and automotive parts industries to produce rubber rings of various specifications to meet the needs of different fields. It features high-efficiency production and can quickly cut rubber rings, thereby improving production efficiency.

[0003] A search revealed Chinese patent publication number CN217751604U, which relates to the technical field of cutting devices, particularly a high-stability rubber ring cutting device. The device includes a base and a roller assembly. The roller assembly is mounted on the base, and the rubber ring is hung on the outer wall of the roller assembly. A cutter wheel seat is located near the roller assembly on the base, and a cutter wheel is detachably mounted on the cutter wheel seat, aligning with the outer wall of the rubber ring. A cutter wheel leveling component is mounted at the bottom of the cutter wheel seat, and a cutter wheel height adjusting component is mounted on the side wall of the cutter wheel seat. This application provides a high-stability rubber ring cutting device to improve the cutting efficiency of the rubber ring, thereby increasing the cutting accuracy. However, during the cutting process, due to the strong extensibility of rubber, the excess material produced during cutting tends to stick together. This excess material easily adheres to the rubber ring or the cutter wheel, negatively impacting product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rubber ring cutting machine, which aims to improve the problem in the prior art where the leftover material produced during cutting sticks together, resulting in adverse effects on product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rubber ring cutting machine, comprising a worktable, a bracket fixedly connected to the top rear end of the worktable, a hydraulic column fixedly connected to the top of the bracket, the output end of the hydraulic column penetrating the interior of the bracket and fixedly connected to a pre-extrusion mold, a mounting plate fixedly connected to the top of the rear side of the worktable, an electric telescopic rod fixedly connected to the top of the mounting plate, a rotating shaft fixedly connected to the output end of the electric telescopic rod, a placement plate fixedly connected to the front side of the rotating shaft, the pre-extrusion mold and the placement plate engaging with each other, movable slide grooves provided on the left and right sides of the top of the worktable, movable plates slidably connected inside the two movable slide grooves, an extended handle fixedly connected to the top of the movable plate, a scraper fixedly connected to the bottom of the movable plate, the bottom end of the scraper abutting against the top of the placement plate, a discharge port provided in the center of the top of the worktable, and a weight warning mechanism provided on the front and rear sides of the inner wall of the worktable.

[0006] The above technical solution involves using a handle to push a moving plate and scraper to clean up the excess rubber ring material that has already been cut on the top of the placement plate. This achieves precise cutting of the rubber ring, ensuring that the size and shape meet the requirements, while also facilitating the cleaning of excess material, thus improving work efficiency and product quality.

[0007] As a further description of the above technical solution:

[0008] The weight warning mechanism includes two mounting grooves, which are respectively located on the lower middle part of the front and rear sides of the inner wall of the workbench. A limit trapezoidal block is fixedly connected to the front side of the bottom of each of the two mounting grooves. A loading box is slidably connected inside each of the two mounting grooves. Multiple fixing plates are fixedly connected to the bottom of the workbench. Two weight sensing blocks are fixedly connected to the bottom of each of the multiple fixing plates. Tension springs are fixedly connected to the top of each of the multiple weight sensing blocks. Ball bearings are fixedly connected to the top of each of the multiple tension springs. An alarm light is fixedly connected to the front side of the top of the bracket. The alarm light is electrically connected to the multiple weight sensing blocks.

[0009] The above technical solution involves placing the loading box in the installation groove. The weight sensor block inside the fixing plate weighs the loading box through a tension spring and ball bearings. When the weight reaches a predetermined threshold, the weight sensor block transmits a signal to the alarm light, thus realizing real-time monitoring of the loading box's weight and avoiding the problem of difficulty in handling due to excessive weight.

[0010] As a further description of the above technical solution:

[0011] A control console is fixedly connected to the top front end of the workbench, and control buttons are fixedly connected to the top of the control console.

[0012] The above technical solution provides a mounting location for the control buttons on the control console, which can control the hydraulic column and electric telescopic rod in the rubber ring cutting machine.

[0013] As a further description of the above technical solution:

[0014] A weight indicator is fixedly connected to the top left side of the workbench, and the weight indicator is electrically connected to multiple weight sensing blocks.

[0015] Through the above technical solution, the weight indicator can display the weight of the items in the loading box in real time, allowing operators to intuitively understand the weight of the loading box without having to obtain it through other complicated methods.

[0016] As a further description of the above technical solution:

[0017] The workbench is fixedly connected to four corners at the bottom, and the bottoms of all the anti-slip legs are designed with a frosted finish.

[0018] The above technical solution involves installing anti-slip support legs at the four corners of the bottom of the workbench. The frosted bottom provides stable support for the workbench and prevents the equipment from sliding due to vibration or external forces during operation.

[0019] As a further description of the above technical solution:

[0020] A buzzer is fixedly connected to the front of the alarm light, and the buzzer is electrically connected to the alarm light.

[0021] With the above technical solution: when the alarm light comes on, indicating that the weight of the loading box has reached the set threshold, the buzzer will also sound an alarm. This sound alarm can more intuitively remind the operator to pay attention to the overloading of the loading box, based on the visual alarm.

[0022] As a further description of the above technical solution:

[0023] The bottom of the mounting plate is fixedly connected to two diagonal braces, and the bottom ends of the two diagonal braces are fixedly connected to the middle of the rear side of the workbench.

[0024] Through the above technical solution, the diagonal brace can ensure that the mounting plate will not deform or shake when subjected to these forces, thereby ensuring the positioning accuracy of the plate.

[0025] As a further description of the above technical solution:

[0026] The outer wall of the loading box is fixedly connected to multiple handles, and the outer walls of the multiple handles are all designed to be non-slip.

[0027] The above technical solution enables operators to easily pull the loading box, and its anti-slip design on the outer wall can prevent accidents caused by slipping hands during operation, thus improving the safety and convenience of operation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the leftover rubber ring material after being cut on the top of the placement plate is cleaned by pushing the moving plate and scraper with the handle, which realizes the precise cutting of the rubber ring, ensures that the size and shape meet the requirements, and facilitates the cleaning of the leftover material, thereby improving work efficiency and product quality.

[0030] 2. In this utility model, the loading box is placed in the mounting groove, and the weight sensing block inside the fixing plate weighs the loading box through the tension spring and ball bearings. When the weight reaches the predetermined threshold, the weight sensing block transmits a signal to the alarm light, realizing real-time monitoring of the weight of the loading box and avoiding the problem of difficulty in handling due to excessive weight.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a rubber ring cutting machine, including a worktable 1. A bracket 3 is fixedly connected to the top rear end of the worktable 1, which provides a support position for subsequently installed components to ensure the stability of the entire structure. A hydraulic column 4 is fixedly connected to the top of the bracket 3, which provides power to enable the pre-extrusion mold 5 to move up and down. The output end of the hydraulic column 4 passes through the interior of the bracket 3 and is fixedly connected to the pre-extrusion mold 5. The pre-extrusion mold 5 is used to cut rubber material placed on a placement plate 9. A mounting plate 6 is fixedly connected to the top rear side of the worktable 1, which provides an installation position for an electric telescopic rod 7. The electric telescopic rod 7 is fixedly connected to the top of the mounting plate 6, which can control the front and rear position of the placement plate 9 to better cooperate with the pre-extrusion mold 5. A rotating shaft 8 is fixedly connected to the output end of the electric telescopic rod 7, which connects the electric telescopic rod 7 and the placement plate 9 and allows the placement plate 9 to rotate around the rotating shaft 8 at a certain angle. The placement plate 9 is fixedly connected to the front side of the rotating shaft 8. 9 is used to place rubber material for cutting operations. The pre-extrusion mold 5 and the placement plate 9 mesh with each other to ensure that the rubber material can be accurately cut during the cutting process. The top left and right sides of the workbench 1 are provided with movable slide grooves 10, which provide sliding tracks for the movable plate 11. The movable plate 11 is slidably connected inside the two movable slide grooves 10. The movable plate 11 can slide in the movable slide grooves 10, driving the scraper 13 to move. The top of the movable plate 11 is fixedly connected with an extension handle 12, which facilitates operation. The operator holds the movable plate 11 to push it. A scraper 13 is fixedly connected to the bottom of the movable plate 11. The scraper 13 is used to clean the residual material on the placement plate 9. The bottom end of the scraper 13 is attached to the top of the placement plate 9 to ensure that the residual material can be effectively cleaned. A discharge port 14 is opened in the center of the top of the workbench 1. The discharge port 14 is used to discharge the residual material after cleaning. A weight warning mechanism 2 is provided on the front and rear sides of the inner wall of the workbench 1. The weight warning mechanism 2 is used to monitor the weight of the items in the loading box 203 and issue an alarm when the weight is too high.

[0040] Specifically, the hydraulic column 4 is activated, and its output end pushes the pre-extrusion mold 5 downward. Because the pre-extrusion mold 5 and the placement plate 9 mesh with each other, the placement plate 9 remains stable under the action of the pre-extrusion mold 5. The hydraulic column 4 provides strong and stable downward pressure to ensure accurate matching between the pre-extrusion mold 5 and the placement plate 9, laying the foundation for cutting. At the same time, the placement plate 9 is connected to the output end of the electric telescopic rod 7 through the rotating shaft 8. The electric telescopic rod 7 can control the front and rear position of the placement plate 9, improving the accuracy of the matching between the pre-extrusion mold 5 and the placement plate 9, which helps to cut rubber rings that meet the requirements. The rubber material is placed on the placement plate 9, and the hydraulic column 4 drives the pre-extrusion mold 5 to press down for cutting. The downward pressure of the hydraulic column 4 causes the pre-extrusion mold 5 to engage with the rubber. Sufficient pressure is applied to the rubber material to achieve precise cutting, ensuring that the size and shape of the rubber ring meet the requirements. The cut rubber ring is left on the placement plate 9, and the excess material will remain on the surface. After the placement plate 9 falls into the discharge port 14, the top surface will flip forward with the rotating shaft 8. Then, by extending the handle 12, the moving plate 11 is pushed so that the scraper 13 is in contact with the top surface of the placement plate 9, which can effectively scrape off the excess material. The scraped excess material is discharged through the discharge port 14 at the top center of the worktable 1. The discharge port 14 provides a convenient channel for the discharge of excess material to avoid accumulation and affect subsequent cutting. This makes the rubber ring cutting machine complete the cutting work efficiently and accurately, and facilitates the cleaning of excess material, thereby improving work efficiency and product quality.

[0041] Reference Figure 2 , Figure 4 and Figure 5 The weight warning mechanism 2 includes two mounting grooves 201, which are respectively located on the lower middle part of the front and rear sides of the inner wall of the workbench 1. Their function is to provide space for the installation and sliding of the loading box 203. A limiting trapezoidal block 202 is fixedly connected to the front side of the bottom of each mounting groove 201. The limiting trapezoidal block 202 is used to limit the sliding range of the loading box 203, ensuring its stable sliding in a specific position. The loading box 203 is slidably connected inside each of the two mounting grooves 201. The loading box 203 is used to place items, and its weight changes will be monitored. Multiple fixing plates 204 are fixedly connected to the bottom of the workbench 1. The fixing plates 204 provide installation positions for the weight sensing block 205. The bottom of the multiple fixing plates 204 are fixedly connected to... Two weight sensing blocks 205 are connected to the support 3. The weight sensing blocks 205 are used to sense the weight pressure transmitted by the loading box 203. Tension springs 206 are fixedly connected to the top of each weight sensing block 205. The tension springs 206 deform according to the pressure on the weight sensing blocks 205, which plays the role of transmitting and buffering the weight pressure. Ball bearings 207 are fixedly connected to the inner top of each tension spring 206. The ball bearings 207 move with the deformation of the tension springs 206 to help judge the weight change. An alarm light 208 is fixedly connected to the top front of the support 3. The alarm light 208 is used to issue a visual alarm when the weight exceeds the limit. The alarm light 208 is electrically connected to the multiple weight sensing blocks 205 to ensure that the alarm light 208 can be triggered in time when the weight exceeds the limit.

[0042] Specifically, two mounting grooves 201 are respectively located on the lower middle part of the front and rear sides of the inner wall of the workbench 1. This provides specific positional and spatial guidance for the installation and sliding of the loading box 203. The limiting trapezoidal block 202 fixedly connected to the front bottom of the mounting groove 201 plays a key positioning and limiting role. It ensures that the loading box 203 can slide stably in the groove and is restricted in a specific position to prevent it from sliding excessively or falling out of the groove, thereby ensuring the stability and reliability of the entire mechanism. The loading box 203 slides in the two mounting grooves 201. It is a container for placing items. When an item is placed in the loading box 203, its weight will affect the entire mechanism. The bottom of the multiple fixed plates 204 fixedly connected to the bottom of the workbench 1 is fixedly connected to two weight sensing blocks 205. These weight sensing blocks 205 are the core detection components of the entire early warning mechanism. When there is an item in the loading box 203, the weight of the item will be transmitted to the mounting groove 201 through the loading box 203, and then through the mounting groove 201. The relevant structure of the contact ultimately transmits the pressure to the weight sensor block 205. The tension spring 206, which is fixedly connected to the top of the weight sensor block 205, will deform accordingly according to the pressure it receives. Since the weight of the loading box 203 is different, the pressure transmitted to the weight sensor block 205 is also different, and the compression degree of the tension spring 206 will be different. The ball bearing 207 at the top of the tension spring 206 will change position as the spring is compressed. When the weight of the loading box 203 reaches the set threshold, the weight sensor block 205 can accurately detect the change in pressure and quickly transmit this signal to the alarm light 208 that is electrically connected to it. The alarm light 208 is fixed to the top front side of the bracket 3. After receiving the signal, it will light up, thereby issuing a weight warning information to the operator. The weight sensor block 205 weighs and calculates the weight of the loading box 203 and the items inside the loading box 203, and issues an alarm in time through the alarm light 208 when the weight reaches the warning value, effectively avoiding the problem of difficulty in handling due to overloading.

[0043] Reference Figure 1 and Figure 2A control console 15 is fixedly connected to the top front end of the workbench 1. The control console 15 provides an installation position for the control buttons 16. Its function is to facilitate the operation of related equipment by the operator. The control buttons 16 are fixedly connected to the top of the control console 15. The control buttons 16 are used to control various operations of the rubber ring cutting machine, such as starting or stopping the equipment. A weight indicator 17 is fixedly connected to the top left side of the workbench 1. The weight indicator 17 is used to display the weight information of the items in the loading box 203. Its function is to allow the operator to intuitively understand the loading weight. The weight indicator 17 is electrically connected to multiple weight sensing blocks 205 to ensure accurate acquisition and display of weight data. Anti-slip legs 18 are fixedly connected to the four corners of the bottom of the workbench 1. The anti-slip legs 18 provide stable support for the workbench 1. Their function is to prevent the equipment from sliding during operation. The bottom of multiple anti-slip legs 18 is designed with a frosted finish. The frosted finish further enhances the anti-slip effect and ensures that the equipment is placed more stably.

[0044] Specifically, the control console 15 provides an installation position for the control button 16, which can control the hydraulic column 4 and the electric telescopic rod 7 in the rubber ring cutting machine. The weight indicator 17 can display the weight of the items in the loading box 203 in real time, so that the operator can intuitively understand the weight of the loading box 203 through the weight indicator 17 without having to obtain it through other complicated methods. The anti-slip support legs 18 are installed at the four corners of the bottom of the workbench 1. The bottom of the legs is designed with a frosted finish to provide stable support for the workbench 1 and prevent the equipment from sliding due to vibration or external force during operation.

[0045] Reference Figure 1 , Figure 2 and Figure 3 A buzzer 19 is fixedly connected to the front of the alarm light 208. The buzzer 19 is used to sound an alarm when the alarm light 208 is lit. Its function is to enhance the overload warning effect and make it easier for operators to notice. The buzzer 19 is electrically connected to the alarm light 208 to ensure that sound and visual alarms can be triggered simultaneously when the weight exceeds the limit. Two diagonal braces 20 are fixedly connected to the bottom of the mounting plate 6. The diagonal braces 20 are used to enhance the stability of the mounting plate 6. Their function is to prevent the mounting plate 6 from deforming or shaking during equipment operation. The bottom ends of the two diagonal braces 20 are fixedly connected to the middle of the rear side of the workbench 1 to ensure that the diagonal braces 20 can effectively support the mounting plate 6. Multiple handles 21 are fixedly connected to the outer wall of the loading box 203. The handles 21 facilitate the operation of the loading box 203 by the operator. Their function is to facilitate pulling or moving the loading box 203. The outer walls of the multiple handles 21 are all designed with anti-slip to prevent the operator's hands from slipping and ensure operation safety.

[0046] Specifically, when the alarm light 208 illuminates, indicating that the weight of the loading box 203 has reached the set threshold, the buzzer 19 will simultaneously emit an audible alarm. This audible alarm, in addition to the visual alarm, provides a more intuitive reminder to the operator that the loading box 203 is overloaded. Since the electric telescopic rod 7 is installed on the mounting plate 6 and generates a certain force during operation, the diagonal brace 20 ensures that the mounting plate 6 will not deform or shake when bearing these forces, thereby ensuring the positional accuracy of the placement plate 9. The handle 21 facilitates the operator in pulling the loading box 203, and its anti-slip design on the outer wall prevents accidents caused by the operator's slipping hands during operation, improving the safety and convenience of operation.

[0047] Working principle: When the hydraulic column 4 is activated, its output end pushes the pre-extrusion mold 5 downward. Because the pre-extrusion mold 5 and the placement plate 9 mesh with each other, the placement plate 9 remains stable under the action of the pre-extrusion mold 5. The hydraulic column 4 provides strong and stable downward pressure, ensuring accurate matching between the pre-extrusion mold 5 and the placement plate 9, laying the foundation for cutting. Simultaneously, the placement plate 9 is connected to the output end of the electric telescopic rod 7 via the rotating shaft 8. The electric telescopic rod 7 can control the front and rear position of the placement plate 9, improving the accuracy of the matching between the pre-extrusion mold 5 and the placement plate 9, which helps to cut rubber rings that meet the requirements. The rubber material is placed on the... On the placement plate 9, the hydraulic column 4 drives the pre-extrusion mold 5 to press down and cut. The hydraulic column 4 presses down so that the pre-extrusion mold 5 applies sufficient pressure to the rubber material to achieve precise cutting and ensure that the size and shape of the rubber ring meet the requirements. The cut rubber ring is left on the placement plate 9, and the excess material will remain on the surface. After the placement plate 9 falls into the discharge port 14, the top surface will flip forward with the rotating shaft 8. Then, by extending the handle 12, the moving plate 11 is pushed so that the scraper 13 is in contact with the top surface of the placement plate 9, which can effectively scrape off the excess material. The scraped excess material is discharged through the discharge port 14 at the top center of the worktable 1.

[0048] Furthermore, two mounting grooves 201 are respectively formed on the lower middle part of the front and rear sides of the inner wall of the workbench 1. This provides specific position and spatial guidance for the installation and sliding of the loading box 203. The limiting trapezoidal block 202 fixedly connected to the front bottom of the mounting groove 201 plays a key positioning and limiting role. It ensures that the loading box 203 can slide stably in the groove and is restricted in a specific position to prevent it from sliding excessively or falling out of the groove, thereby ensuring the stability and reliability of the entire mechanism. The loading box 203 slides in the two mounting grooves 201. It is a container for placing items. When the items are put into the loading box 203, their weight will affect the entire mechanism. The bottom of the multiple fixed plates 204 fixedly connected to the bottom of the workbench 1 is fixedly connected to two weight sensing blocks 205. It is the core detection component of the entire early warning mechanism. When there are items in the loading box 203, the weight of the items will be transmitted to the mounting slide 201 through the loading box 203, and then to the weight sensing block 205 through the related structure in contact with the mounting slide 201. The tension spring 206 fixedly connected to the top of the weight sensing block 205 will deform accordingly according to the pressure it receives. Since the weight of the loading box 203 is different, the pressure transmitted to the weight sensing block 205 is also different, and the degree of compression of the tension spring 206 will be different. The ball 207 on the top of the tension spring 206 will change position as the spring is compressed. When the weight of the loading box 203 reaches the set threshold, the weight sensing block 205 can accurately detect the pressure change and quickly transmit this signal to the alarm light 208 that is electrically connected to it.
