Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, and particularly relates to a rubber conveyor belt cutting machine. Background Technique

[0002] As a main structural part of a transmission device, a rubber conveyor belt is a key structure for realizing the transmission of goods. Therefore, improving the quality of the rubber conveyor belt is a condition for ensuring the normal operation of the transmission device.

[0003] When a rubber conveyor belt is processed, it is usually realized through a rubber extrusion structure and a calendering mechanism. For example, a manufacturing device for a rubber conveyor belt disclosed in Patent CN201559959U adds raw materials into an extrusion mechanism and transports them to a calendering mechanism by a spiral extrusion mechanism for sheet pressing and cooling. Since the processing equipment is located in a limited space such as a processing workshop, during processing, the manufactured rubber conveyor belt is usually cut into multiple strip-shaped belts of a predetermined length and wound into a belt roll. In addition, since the produced rubber conveyor belt is usually a single-layer strip, its two ends need to be spliced together later to form a ring-shaped rubber conveyor belt for use. In addition, since the transmission strokes in different specifications and models of transmission devices are different, the lengths of the rubber conveyor belts used are also different. Therefore, the rubber conveyor belt needs to be cut into the required length according to the need and then spliced. It can be seen that during the processing of the rubber conveyor belt, it needs to be cut frequently to meet different processing requirements. However, the existing methods for cutting rubber conveyor belts are relatively traditional, and usually the method of manually holding scissors or a cutter is used for cutting. Although the above manual cutting method can meet the cutting requirements, during the manual cutting process, problems such as uneven cutting surfaces are likely to occur due to hand shaking and differences in the magnitude of the applied force. In addition, during the cutting process, when the rubber conveyor belt with a certain elasticity is not completely cut off, the cut end surface will interfere with the cutter and other components, affecting the movement of the cutter, resulting in a deviation of the cutting trajectory, making the cross-section uneven. In addition, it also increases the cutting resistance and the labor burden is heavier, which is not conducive to the cutting of the rubber conveyor belt. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the present invention aims to provide a rubber conveyor belt cutting machine, which is provided with clamping seats arranged side by side and at intervals on a frame, and a telescopic cutting assembly is arranged on the frame and between the two clamping seats. The two ends of the rubber conveyor belt to be cut are clamped by the two clamping seats respectively, and then the middle part of the clamped rubber conveyor belt is cut by the telescopic cutting assembly. Moreover, a yawing assembly is installed on each clamping seat, and through the yawing assembly, the two ends of the rubber conveyor belt to be cut can be gradually pulled apart during the cutting process, which can not only make the cutting more labor-saving, but also reduce the cutting error and ensure the flatness of the cross-section. Compared with manual cutting, it not only improves the cutting efficiency and quality, but also reduces the labor burden and meets the large-scale cutting and processing requirements of rubber conveyor belts.

Detailed Description of the Preferred Embodiment

[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following embodiments are combined with the attached Figure 1 to the attached Figure 5A detailed description of the technical solution provided by the present utility model is given below, but the following content is not a limitation of the present utility model.

[0029] Figure 1 It is a structural diagram of an embodiment of a rubber conveyor belt cutting machine of the present utility model; Figure 2 It is a structural diagram of a rubber conveyor belt cutting machine of the present utility model after the outer cover is opened. As Figure 1 and Figure 2 shown, the rubber conveyor belt cutting machine provided in this embodiment includes: a frame 1, a clamping seat 2, a telescopic cutting assembly 3, and a yaw assembly 4.

[0030] Specifically, the frame 1 is of a frame structure, so that it has both a supporting ability and a sufficiently large inner cavity, facilitating the built-in installation of other structural parts. In addition, the frame 1 includes two spaced-apart mounting rods 11, so that there is a space between the two mounting rods 11 to facilitate the installation and movement of other structural parts. At the same time, the two mounting rods 11 also serve as connection and mounting structures for other structural parts to be mounted on the frame 1.

[0031] Figure 3 It is a combined installation diagram of the clamping seat and the yaw assembly of a preferred embodiment of the present utility model. As Figure 2 and Figure 3 shown, two clamping seats 2 are provided on the frame 1. At this time, the two clamping seats 2 are arranged side by side and spaced apart on the frame 1, so that the arrangement directions of the two clamping seats 2 are the same. Preferably, each clamping seat 2 is arranged along the width direction of the rubber conveyor belt to be cut, which is convenient for fully pressing the rubber conveyor belt to be cut, providing conditions for subsequent transverse cutting of the rubber conveyor belt. In addition, the two clamping seats 2 can respectively press the two ends of the rubber conveyor belt to be cut, ensuring the stability of the rubber conveyor belt during the cutting process, and thus ensuring the quality of the cut surface. At this time, each clamping seat 2 further includes a carrier plate 21, a lower clamping block 22, an upper clamping block 23, and a pressing driver 24. During installation, the two ends of the carrier plate 21 are respectively installed on the two mounting rods 11, realizing the installation of the carrier plate 21 on the frame 1. At the same time, the lower clamping block 22 is installed on the carrier plate 21, and the pressing driver 24 is installed on the carrier plate 21, so that the driving shaft of the pressing driver 24 can move relative to the lower clamping block 22 on the carrier plate 21. In addition, the upper clamping block 23 is arranged above the lower clamping block 22 and is power-connected to the driving shaft of the pressing driver 24. In the initial state, the driving shaft of the pressing driver 24 extends, so that the upper clamping block 23 is far from the lower clamping block 22, and there is a gap between the upper clamping block 23 and the lower clamping block 22, facilitating the smooth insertion of the rubber conveyor belt to be cut between the upper clamping block 23 and the lower clamping block 22. Before cutting is required, the retraction of the driving shaft of the pressing driver 24 drives the upper clamping block 23 to move towards the lower clamping block 22, and the upper clamping block 23 and the lower clamping block 22 press the end of the rubber conveyor belt to be cut located between the two, providing conditions for subsequent cutting.

[0032] Figure 4 This is a structural diagram of the telescopic cutting assembly of a preferred embodiment of the present utility model. As Figure 2 and Figure 4 shown, the telescopic cutting assembly 3 for cutting the rubber conveyor belt further includes a cutting driver 31, a tool holder 32, and a blade 33. During installation, the cutting driver 31 is arranged along a direction parallel to the carrier plate 21, such that the moving direction of the cutting driver 31 is the width direction of the rubber conveyor belt. At this time, the tool holder 32 is power-connected to the drive shaft of the cutting driver 31, and the blade 33 is installed on the tool holder 32, such that when the blade 33 is driven to move by the cutting driver 31 and the tool holder 32 subsequently, the blade 33 can move along the width direction of the rubber conveyor belt, thereby transversely cutting the rubber conveyor belt to meet the cutting requirement. Moreover, it can also avoid the problem that the cross-section to be cut is too large when the blade 33 feeds, making the cutting easier.

[0033] Specifically, each clamping seat 2 corresponds to a yaw assembly 4, such that each clamping seat 2 can deflect under the action of the corresponding yaw assembly 4, thereby pulling apart the two ends of the rubber conveyor belt, facilitating cutting and ensuring the cutting quality. At this time, the yaw assembly 4 further includes a turntable 41, a swing arm 42, a guide plate 43, and a lifting driver 44. During installation, the turntable 41 is arranged at both ends of the carrier plate 21 of the corresponding clamping seat 2 and installed on the two mounting rods 11, that is, both ends of the carrier plate 21 are installed on the two mounting rods 11 through the turntable 41, so that the carrier plate 21 can rotate through the turntable 41, providing the condition for the subsequent yaw of the clamping seat 2. In addition, one end of the swing arm 42 is connected to the carrier plate 21 of the corresponding clamping seat 2, such that the swing arm 42 can drive the corresponding carrier plate 21 to yaw. Moreover, a guide shaft 421 is provided at the other end of the swing arm 42, such that the other end of the swing arm 42 can be used in cooperation with other structures through the guide shaft 421. At this time, the lifting driver 44 is installed on the frame 1, and a guide plate 43 is installed on the lifting shaft of the lifting driver 44. A guide groove 431 inclined in the vertical direction is provided on the guide plate 43, and the guide shaft 421 is slidably arranged in the corresponding guide groove 431. That is, when the lifting shaft of the lifting driver 44 drives the guide plate 43 to move up and down in the vertical direction, the guide shaft 421 slides into different positions in the guide groove 431. Since the guide groove 431 is inclined in the vertical direction, when the guide shaft 421 slides in the guide groove 431, the position of the guide shaft 421 in the horizontal direction will gradually change, thereby driving the swing arm 42 to deflect, and then driving the carrier plate 21 connected to the swing arm 42 to rotate around the turntable 41, realizing the yaw of the corresponding clamping seat 2. It is worth noting that the yaw direction of the swing arm 42 is controlled by the inclination direction of the guide groove 431 on the guide plate 43, so as to meet the requirement that the two clamping seats 2 yaw towards the opposite sides to achieve the purpose of pulling apart the rubber conveyor belt, and the structural design is more reasonable.

[0034] Figure 5 The structural diagram of the material pushing assembly of a preferred embodiment of the present utility model is shown as follows. As Figure 1 , Figure 2 and Figure 5 shown, each clamping seat 2 also corresponds to a material pushing assembly 5, so that the position of the rubber conveyor belt to be cut can be adjusted by the material pushing assembly 5 before it is pressed, ensuring that the position of the rubber conveyor belt to be cut can be more accurate. The two material pushing assemblies 5 are arranged in parallel on the side of the carrier plate 21 corresponding to the clamping seat 2. The material pushing assembly 5 includes a support plate 51, a positioning stop block 52, a material pushing driver 53 and a pushing block 54. The support plate 51 is horizontally arranged and parallel to the corresponding carrier plate 21, and the bottom of the support plate 51 is installed on the frame 1. At this time, a positioning stop block 52 is fixedly installed at one end of the support plate 51. At the same time, the material pushing driver 53 is installed at the other end of the support plate 51 and arranged towards the positioning baffle, and the pushing block 54 is installed on the driving shaft of the material pushing driver 53, so that when the material pushing driver 53 expands and contracts, it can drive the pushing block 54 to approach or move away from the positioning stop block 52, that is, when the rubber conveyor belt to be cut passes through the material pushing assembly 5 and the corresponding clamping seat 2, before the clamping seat 2 is pressed, the rubber conveyor belt to be cut is pushed towards the positioning stop block 52 through the movement of the pushing block 54, so as to realize the position adjustment of the rubber conveyor belt to be cut, ensure that the rubber conveyor belt can be accurately positioned when pressed, and thus ensure the quality of the cut section.

[0035] More specifically, the turntable 41 of the yaw assembly 4 further includes a fixed seat 411, a rotating shaft 412 and a support seat 413. At this time, the fixed seat 411 is installed on the mounting rod 11, the rotating shaft 412 is arranged along the length direction of the carrier plate 21 and one end is rotatably installed on the fixed seat 411, and one end of the support seat 413 is installed on the other end of the rotating shaft 412, and the other end of the support seat 413 is connected to the corresponding carrier plate 21, so that the carrier plate 21 can rotate through the rotating shaft 412, and the carrier plate 21 rotates around the axis in its length direction to meet the use requirements. Preferably, the support seat 413 is arranged in an "L" shape. One side of the vertical end of the support seat 413 is connected to the rotating shaft 412, and the horizontal end of the support seat 413 supports the end of the corresponding carrier plate 21, providing a larger bearing area for the installation of the carrier plate 21 and making the installation of the carrier plate 21 more stable and reliable.

[0036] More specifically, two pressing drivers 24 are provided for each clamping seat 2. At this time, the two pressing drivers 24 are respectively arranged at both ends of the corresponding carrier plate 21, and the driving shafts of the two pressing drivers 24 are respectively connected to both ends of the upper pressing block, so that both ends of the upper pressing block are connected with driving structures, so that the upper pressing block can be balanced in force, ensuring that the rubber conveyor belt to be cut can be more stable and reliable after being pressed.

[0037] More specifically, anti-slip teeth 221 are further provided on the upper pressing block and / or the lower pressing block and on the opposite sides. By adding the anti-slip teeth 221 on the upper pressing block and / or the lower pressing block, the friction force can be increased when the rubber conveyor belt to be cut is pressed by the upper pressing block and the lower pressing block, the pressing effect is better, and it is not easy to loosen.

[0038] More specifically, the telescopic cutting assembly 3 further includes a sliding frame 34. The tool holder 32 is supported by the sliding frame 34 to improve the stability of the tool holder 32 when it moves. At this time, the sliding frame 34 further includes a guide rail 341 and a sliding carriage 342. During installation, both ends of the guide rail 341 are respectively installed on the two mounting rods 11 and arranged parallel to the carrier plate 21, so that the arrangement direction of the guide rail 341 is also the width direction of the rubber conveyor belt to be cut, meeting the cutting requirements. And, the sliding carriage 342 is slidably disposed on the guide rail 341, and the tool holder 32 is installed on the sliding carriage 342. That is, the sliding carriage 342 provides support for the tool holder 32 and at the same time adapts to the movement requirements of the tool holder 32, making the tool holder 32 move more stably and further ensuring the quality of the cross-section formed after cutting.

[0039] More specifically, the tool holder 32 for installing the blade 33 further includes an upper support arm 321, a lower support arm 322 and an intermediate block 323. During installation, the upper support arm 321 and the lower support arm 322 are arranged at intervals in the vertical direction in an upper and lower layer manner. At the same time, both the upper support arm 321 and the lower support arm 322 are arranged parallel to the carrier plate 21, and an intermediate block 323 is provided between one ends of the upper support arm 321 and the lower support arm 322, so that there is an interval between the upper support arm 321 and the lower support arm 322, providing conditions for the subsequent passage of the rubber conveyor belt to be cut. When installing the blade 33, the blade 33 is installed between the other ends of the lower support arm 322 of the upper support arm 321, so that both ends of the blade 33 can be respectively located above and below the rubber conveyor belt to be cut, thus providing conditions for the blade 33 to cut the rubber conveyor belt horizontally. In addition, both ends of the blade 33 are supported, maintaining the stability of the blade 33 during cutting, and the structural design is more reasonable. Preferably, the bottom of the lower support arm 322 is installed on the sliding carriage 342, so that the sliding carriage 342 can support the tool holder 32. When the tool holder 32 is driven by the drive shaft of the cutting driver 31 to expand and contract, the sliding of the sliding carriage 342 on the guide rail 341 can provide support and guidance for the tool holder 32, ensuring that the blade 33 can be more stable during the cutting process.

[0040] More specifically, the guide plate 43 for driving the swing of the swing arm 42 is arranged in a "U" shape. At this time, both sides of the open end of the guide plate 43 are arranged towards the swing arms 42 of the two swing assemblies 4, so that one guide plate 43 can act on the two swing arms 42 at the same time, enabling the two clamping seats 2 to swing simultaneously, reducing the swing stroke of each clamping seat 2 and making it easier to achieve. In addition, guide grooves 431 are provided on both sides of the open end of the guide plate 43, and the two guide grooves 431 respectively correspond to the guide shafts 421 of one swing arm 42. The middle part of the non-open end of the guide plate 43 is connected to the lifting shaft of the lifting driver 44. When the lifting driver 44 drives the guide plate 43 to lift and lower, the two guide grooves 431 on the guide plate 43 can simultaneously push the corresponding guide shafts 421 to slide, thereby realizing the swing of the corresponding swing arm 42. The structural utilization rate is higher, and at the same time, the synchronous movement of the two clamping seats 2 is ensured, ensuring the quality of the cut section.

[0041] More specifically, an outer cover 6 is further provided on the frame 1. At this time, the outer cover 6 is covered outside the clamping seat 2, the telescopic cutting assembly 3 and the swing assembly 4, realizing outer protection through the outer cover 6 and having higher safety guarantee. In addition, an inlet and an outlet are opened on the outer cover 6, and the inlet and outlet respectively correspond to the two clamping seats 2, facilitating the entry and exit of the rubber conveyor belt to be cut. And one side of the outer cover 6 is hinged to the frame 1, and a handle 61 is provided on the other side of the outer cover 6, enabling the operator to flip the outer cover 6 through the handle 61 to realize the opening and closing of the outer cover 6. At the same time, a plurality of telescopic struts are provided between the outer cover 6 and the frame 1. Preferably, the telescopic struts are hydraulic support rods, which can temporarily support the outer cover 6 through the telescopic struts when the outer cover 6 is turned up and opened. Since the telescopic struts are common structures on the market, such as the telescopic struts on the rear door of a car, appropriate telescopic struts can be selected and used in this embodiment, so their specific structures will not be described in detail here.

[0042] More specifically, an observation window 62 is further opened on the outer cover 6. The observation window 62 corresponds to the interval between the two clamping seats 2, and a transparent cover is provided on the observation window 62, enabling the operator to observe the cutting state in real time through the observation window 62 during the cutting process to ensure the smooth progress of the cutting process.

[0043] The rubber conveyor belt cutting machine provided in this embodiment includes a frame 1, a clamping seat 2, a telescopic cutting assembly 3 and a yaw assembly 4. Two clamping seats 2 are arranged in parallel and at intervals on the frame 1, and the telescopic cutting assembly 3 is arranged between the two clamping seats 2. In addition, a yaw assembly 4 is installed on each clamping seat 2. The two clamping seats 2 can be used to clamp both ends of the rubber conveyor belt to be cut. Then, the blade 33 of the telescopic cutting assembly 3 is used to cut the clamped rubber conveyor belt to be cut. During the cutting process, the corresponding clamping seat 2 is pushed by the yaw assembly 4 to yaw and pull open the cut rubber conveyor belt, which can not only make the cutting more labor-saving, but also reduce the cutting error, make the cut section smoother, facilitate the splicing of the later section. Moreover, the cutting process is realized by a mechanical structure, with higher cutting efficiency and better quality. At the same time, it also reduces the labor burden and meets the processing requirements of high-precision cutting and large-batch cutting of rubber conveyor belts.

[0044] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention.
