Description

Technical Field

[0001] This utility model relates to the technical field of rock wool production and processing equipment, specifically to a rock wool cross-cutting device. Background Technology

[0002] Rock wool products are made primarily from basalt, dolomite, and other raw materials. These materials are melted at high temperatures, centrifuged at high speeds to form fibers, and then processed through collection and curing. Finally, they undergo a cutting process to produce products of different specifications. In the rock wool production process, the cross-cutting equipment is crucial for achieving fixed-length cutting of rock wool, and its performance directly affects the cut quality and production efficiency of the rock wool products.

[0003] In the prior art, Chinese Patent CN219076116U discloses a cross-cutting device for rock wool strip production, which fixes the rock wool through a rock wool strip clamping mechanism and cuts it using a cross-cutting device. However, this type of device has obvious drawbacks: the lifting and lowering action of the cutting saw relies on multiple sets of telescopic rods for driving, while the reciprocating cutting action of the saw blade requires a separate motor, resulting in the need for multiple drive components. This increases the manufacturing cost of the equipment and reduces the product's competitiveness in the market; furthermore, the increased number of drive components makes the equipment structure complex, significantly increasing the difficulty and cost of later maintenance, which is not conducive to large-scale promotion and application. Utility Model Content

[0004] The purpose of this utility model is to provide a rock wool cross-cutting device with a simplified structure, lower cost and convenient maintenance, so as to solve the problems of redundant drive components and excessive cost in the prior art.

[0005] This utility model is achieved through the following technical solution: a rock wool cross-cutting device, comprising:

[0006] The workbench has a mounting frame fixedly connected to its top, and a movable box is slidably disposed within the mounting frame along the vertical direction.

[0007] A cutting saw is movably mounted within the mounting frame, with the top of the cutting saw slidingly engaged with the bottom of the movable box in a horizontal direction;

[0008] A drive mechanism is provided on the movable box, and one end of the drive mechanism is connected to the cutting saw for driving the cutting saw to reciprocate in the horizontal direction.

[0009] The drive mechanism includes a drive assembly, a mounting plate, a mounting rod, and a movable frame. The drive assembly is mounted on the movable frame. The mounting plate is connected to the output end of the drive assembly. The top end of the mounting rod is eccentrically fixed to the bottom of the mounting plate. One end of the movable frame is fixedly connected to the cutting saw. The mounting rod passes through the movable frame and slides with the movable frame.

[0010] A lifting mechanism is provided on the mounting frame. One end of the lifting mechanism is fixedly connected to the mounting frame, and the other end extends into the movable box and is connected to the drive mechanism for driving the movable box to move the cutting saw up and down in the vertical direction.

[0011] A limiting mechanism is provided on the movable box. There are two sets of the limiting mechanism, which are located on both sides of the cutting saw, and are used to limit the rock wool.

[0012] The working principle of this technical solution is as follows: the worktable provides a supporting foundation for the equipment, and the mounting frame on top provides a vertical movement track for the movable box; the movable box achieves overall lifting and lowering through a sliding engagement with the mounting frame. The cutting saw slides horizontally with the bottom of the movable box, allowing it to reciprocate horizontally under the action of the drive mechanism, meeting the cutting action requirements. In the drive mechanism, the mounting plate obtains rotational power through the drive assembly, and its eccentrically fixed mounting rod at the bottom rotates with the mounting plate, converting the rotational motion into the horizontal reciprocating motion of the cutting saw through a sliding engagement with the movable frame (the eccentric structure is the key to achieving reciprocating motion). The lifting mechanism is connected to the drive mechanism, converting the power of the drive mechanism into the vertical lifting power of the movable box, enabling the cutting saw to move up and down simultaneously during reciprocating motion, completing the cutting feed. Two sets of symmetrically distributed limiting mechanisms act synchronously on both sides of the cutting saw, applying pressure to the rock wool through mechanical contact to prevent the rock wool from shifting during the cutting process.

[0013] To better realize this utility model, the driving assembly further includes a driving motor and a driving rod; the driving motor is fixedly connected to the inner wall of the movable box, one end of the driving rod is fixedly connected to the output end of the driving motor, the other end passes through the bottom of the movable box and is rotatably connected to the movable box through a bearing, and the end of the driving rod away from the driving motor is fixedly connected to the center of the mounting plate.

[0014] To better realize this utility model, the lifting mechanism further includes a threaded rod, a threaded sleeve, and a transmission assembly; one end of the threaded rod is rotatably connected to the bottom of the inner wall of the movable box via a bearing, and the other end passes through the top of the movable box and the top of the mounting frame in sequence and extends to the outside of the mounting frame; the threaded sleeve is fixedly connected to the top of the mounting frame, and the threaded sleeve is threadedly engaged with the threaded rod; the transmission assembly is disposed inside the movable box, one end of which is fixedly connected to the drive rod of the drive mechanism, and the other end is fixedly connected to the threaded rod.

[0015] To better realize this utility model, the transmission assembly further includes a driving wheel and a driven wheel; the driving wheel is fixedly connected to the drive rod, the driven wheel is fixedly connected to the threaded rod, and the driving wheel and the driven wheel mesh with each other.

[0016] To better realize this utility model, each set of limiting mechanisms further includes a movable rod, a limiting plate, and a buffer spring; multiple movable rods are provided, each movable rod passes through the movable box in the vertical direction and slides with the movable box; the limiting plate is fixedly connected to the bottom end of each movable rod; multiple buffer springs are provided and correspond one-to-one with each movable rod; one end of each buffer spring is fixedly connected to the upper surface of the limiting plate, and the other end is fixedly connected to the lower surface of the bottom of the movable box.

[0017] To better realize this utility model, further, guide rails are fixedly connected to both sides of the inner wall of the mounting frame, and guide grooves adapted to the guide rails are opened at corresponding positions on both sides of the movable box, and the guide rails and guide grooves are slidably engaged.

[0018] To better realize this utility model, the upper surface of the workbench is provided with scale lines for marking the cutting length of rock wool, and the scale lines extend along the reciprocating motion direction perpendicular to the cutting saw.

[0019] To better realize this utility model, the saw blade of the cutting saw is further provided with a protective cover, which is fixedly connected to the top of the cutting saw, and the bottom of the protective cover is provided with an opening for the saw blade to extend out.

[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0021] (1) This utility model achieves the reciprocating motion and lifting motion of the cutting saw by using a single drive motor through the coordinated design of the drive mechanism and the lifting mechanism. The power output by the drive motor is transmitted to the reciprocating drive structure and the lifting structure of the cutting saw through the transmission components. There is no need to set up multiple sets of telescopic rods or independent drive sources, which greatly reduces the number of drive components, optimizes the overall structure of the equipment, and reduces the production and manufacturing costs and the later maintenance costs.

[0022] (2) This utility model uses two sets of limiting mechanisms symmetrically set on both sides of the cutting saw. During the cutting process, the rock wool can be stably limited to prevent it from shifting due to the reciprocating motion of the cutting saw, thus ensuring a neat cut. At the same time, the buffer spring in the limiting mechanism can buffer the impact force when the limiting plate comes into contact with the rock wool, ensuring the limiting effect and preventing the rock wool from being damaged by pressure.

[0023] (3) The present invention provides precise guidance for the lifting and lowering movement of the movable box by means of the mounting frame and the movable box sliding cooperation through the guide rail and guide groove, so as to avoid the movable box tilting or jamming during the movement; the sliding connection between the cutting saw and the bottom of the movable box ensures the stability of the reciprocating motion and further improves the cutting accuracy.

[0024] (4) The equipment of this utility model has a compact overall structure and is easy to operate. It can be adapted to the cutting needs of rock wool products of different specifications. Furthermore, by simplifying the drive components, the reliability of the equipment is improved and the service life is extended. It is suitable for large-scale rock wool production scenarios.

[0034] Example 1:

[0035] The main structure of this embodiment is as follows: Figures 1-3 As shown, it includes:

[0036] The workbench 1 has a mounting frame 2 fixedly connected to its top, and a movable box 7 is slidably arranged in the vertical direction inside the mounting frame 2;

[0037] The cutting saw 6 is movably disposed within the mounting frame 2, and the top of the cutting saw 6 slides horizontally with the bottom of the movable box 7.

[0038] A drive mechanism is provided on the movable box 7, and one end of the drive mechanism is connected to the cutting saw 6 for driving the cutting saw 6 to reciprocate in the horizontal direction.

[0039] The drive mechanism includes a drive assembly, a mounting plate 41, a mounting rod 42, and a movable frame 43. The drive assembly is mounted on the movable box 7. The mounting plate 41 is connected to the output end of the drive assembly. The top end of the mounting rod 42 is eccentrically fixedly connected to the bottom of the mounting plate 41. One end of the movable frame 43 is fixedly connected to the cutting saw 6. The mounting rod 42 passes through the movable frame 43 and slides with the movable frame 43.

[0040] A lifting mechanism is provided on the mounting frame 2. One end of the lifting mechanism is fixedly connected to the mounting frame 2, and the other end extends into the movable box 7 and is connected to the driving mechanism for driving the movable box 7 to drive the cutting saw 6 to rise and fall in the vertical direction.

[0041] A limiting mechanism is provided on the movable box 7. There are two sets of the limiting mechanism, which are located on both sides of the cutting saw 6, and are used to limit the rock wool.

[0042] The specific implementation process is as follows: Place the rock wool to be cut on the workbench 1 and adjust its position so that the cutting line is directly below the cutting saw 6. Start the equipment, and the drive mechanism begins to work. Through the cooperation of the mounting plate 41, mounting rod 42, and movable frame 43, the cutting saw 6 is driven to reciprocate horizontally to simulate a sawing action. At the same time, the lifting mechanism is activated under the power transmission of the drive mechanism, driving the movable box 7 to slide vertically downward along the mounting frame 2, driving the cutting saw 6 to descend synchronously to achieve cutting feed. During the descent of the movable box 7, the limiting mechanisms on both sides first contact the surface of the rock wool, fixing the rock wool with mechanical pressure. The cutting saw 6 continues to descend and maintain reciprocating motion until the rock wool is cut; after the cutting is completed, the lifting mechanism reverses its action, driving the movable box 7 and the cutting saw 6 to rise and reset, and the limiting mechanisms disengage from the rock wool, completing one cutting cycle.

[0043] Example 2:

[0044] This embodiment further defines the structure of the driving component based on the above embodiments, such as... Figure 3 , Figure 4 As shown, the drive assembly includes a drive motor 441 and a drive rod 442. The drive motor 441 is fixedly connected to the inner wall of the movable box 7. One end of the drive rod 442 is fixedly connected to the output end of the drive motor 441, and the other end passes through the bottom of the movable box 7 and is rotatably connected to the movable box 7 through a bearing. The end of the drive rod 442 away from the drive motor 441 is fixedly connected to the center of the mounting plate 41. The drive motor 441 is fixed to the inner wall of the movable box 7 and outputs rotational torque as a power source. One end of the drive rod 442 is rigidly connected to the output end of the motor, transmitting the torque to the mounting plate 41.

[0045] The drive rod 442 is rotatably connected to the bottom of the movable box 7 via a bearing, which ensures smooth rotation and provides radial support for the drive rod 442, preventing it from shifting due to force.

[0046] The drive rod 442 is fixedly connected to the center of the mounting plate 41, ensuring that the mounting plate 41 rotates stably around the drive rod 442 as the axis, ensuring that the eccentric motion trajectory of the mounting rod 42 is uniform, thereby making the reciprocating motion of the cutting saw 6 stable and controllable.

[0047] The specific implementation process is as follows: When the equipment is started, the drive motor 441 is energized and rotates, and the output end drives the drive rod 442 to rotate synchronously with the bearing to reduce rotational friction. The end of the drive rod 442 away from the motor drives the mounting plate 41 to rotate around the axis of the drive rod 442, and the mounting rod 42 at the bottom of the mounting plate 41 performs an eccentric circular motion accordingly. The mounting rod 42, through sliding engagement with the movable frame 43, converts the eccentric circular motion into a horizontal reciprocating sawing action of the cutting saw 6. At the same time, the drive rod 442 transmits the rotational power to the lifting mechanism, as described in the transmission components of the subsequent embodiments, to provide power for the lifting of the movable box 7. The other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0048] Example 3:

[0049] This embodiment further defines the structure of the lifting mechanism based on the above embodiments, such as... Figure 1 As shown in Figure 4, the lifting mechanism includes a threaded rod 31, a threaded sleeve 32, and a transmission assembly. One end of the threaded rod 31 is rotatably connected to the bottom of the inner wall of the movable box 7 via a bearing, and the other end passes through the top of the movable box 7 and the top of the mounting frame 2, extending to the outside of the mounting frame 2. The threaded sleeve 32 is fixedly connected to the top of the mounting frame 2, and the threaded sleeve 32 is threadedly engaged with the threaded rod 31. The transmission assembly is disposed inside the movable box 7, with one end fixedly connected to the drive rod 442 of the drive mechanism, and the other end fixedly connected to the threaded rod 31. One end of the threaded rod 31 is rotatably connected to the bottom of the movable box 7 via a bearing, allowing it to rotate freely relative to the movable box 7. The other end passes through the movable box 7 and the mounting frame 2, forming a helical pair with the threaded sleeve 32 fixed to the top of the mounting frame 2. When the threaded rod 31 rotates, since the threaded sleeve 32 remains stationary, the relative movement of the helical pair causes the threaded rod 31 to undergo axial displacement, rising or falling, thereby driving the movable box 7 to rise and fall synchronously. The transmission assembly transmits the rotational power of the drive rod 442 to the threaded rod 31, synchronizing the rotation of the threaded rod 31 with the action of the drive mechanism, ensuring that the reciprocating motion and lifting motion of the cutting saw 6 are coordinated.

[0050] The specific implementation process is as follows: When the drive rod 442 rotates, it drives the threaded rod 31 to rotate around its own axis through the transmission assembly, and the bearing cooperation reduces the friction between the threaded rod 31 and the movable box 7. The threaded rod 31 and the threaded sleeve 32 engage in threaded movement. Since the threaded sleeve 32 is fixed on the mounting frame 2, the threaded rod 31 moves axially downwards during cutting feed while rotating. The axial movement of the threaded rod 31 drives the movable box 7 to slide vertically downwards along the guide structure on the inner wall of the mounting frame 2. The cutting saw 6 descends synchronously with the movable box 7, approaches and contacts the rock wool. After cutting is completed, the drive mechanism reverses its action. The drive rod 442 drives the threaded rod 31 to rotate in the opposite direction, and the threaded rod 31 moves axially upwards, driving the movable box 7 and the cutting saw 6 to rise and reset. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0051] Example 4:

[0052] This embodiment further defines the structure of the transmission assembly based on the above embodiments, such as... Figure 3 , Figure 4 As shown, the transmission assembly includes a driving wheel 331 and a driven wheel 332. The driving wheel 331 is fixedly connected to the drive rod 442, and the driven wheel 332 is fixedly connected to the threaded rod 31, with the driving wheel 331 and the driven wheel 332 meshing together. The driving wheel 331 is fixedly sleeved on the drive rod 442 and rotates synchronously with the drive rod 442, serving as the power input end; the driven wheel 332 is fixedly sleeved on the threaded rod 31, serving as the power output end. The driving wheel 331 and the driven wheel 332 mesh with each other, and the rotational power of the driving wheel 331 is transmitted to the driven wheel 332 through the mechanical contact of the gear teeth, thereby driving the threaded rod 31 to rotate. The gear meshing transmission has the characteristics of stable transmission ratio and high efficiency, which can ensure the synchronization of the rotational motion of the drive rod 442 and the threaded rod 31, and ensure the matching accuracy of the reciprocating motion and lifting motion of the cutting saw 6.

[0053] The specific implementation process is as follows: the drive motor 441 drives the drive rod 442 to rotate, and the driving wheel 331 fixed on the drive rod 442 rotates synchronously with it. The driving wheel 331 drives the driven wheel 332 to rotate through tooth surface meshing, and the driven wheel 332 drives the threaded rod 31 to rotate synchronously in the opposite direction to the driving wheel 331. After the threaded rod 31 rotates, it cooperates with the threaded sleeve 32 to generate axial displacement, which drives the movable box 7 to rise and fall. By adjusting the tooth ratio of the driving wheel 331 and the driven wheel 332, the speed ratio of the threaded rod 31 and the drive rod 442 can be adjusted, thereby controlling the lifting speed of the movable box 7 to adapt to the cutting requirements of rock wool of different thicknesses. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0054] Example 5:

[0055] This embodiment further defines the limiting mechanism based on the above embodiments, such as... Figure 2 , Figure 3 As shown, each set of limiting mechanisms includes a movable rod 51, a limiting plate 52, and a buffer spring 53. Multiple movable rods 51 are provided, each penetrating the movable box 7 vertically and slidingly engaging with it. The limiting plate 52 is fixedly connected to the bottom end of each movable rod 51. Multiple buffer springs 53 are provided, each corresponding to one of the movable rods 51. One end of each buffer spring 53 is fixedly connected to the upper surface of the limiting plate 52, and the other end is fixedly connected to the lower surface of the bottom of the movable box 7. Multiple movable rods 51 penetrate the movable box 7 vertically, providing guidance for the limiting plate 52 and ensuring smooth lifting and lowering. The limiting plate 52 is fixedly connected to the bottom end of the movable rods 51, forming a pressure surface that contacts the rock wool. The buffer spring 53 is sleeved on the outside of the movable rods 51, with both ends connected to the limiting plate 52 and the bottom of the movable box 7, respectively. The elastic deformation of the spring absorbs the impact force when the limiting plate 52 contacts the rock wool, preventing damage to the rock wool. When the movable box 7 descends, the limiting plate 52 contacts the rock wool first, the movable rod 51 slides upward relative to the movable box 7, the buffer spring 53 is compressed and generates elastic force, so that the limiting plate 52 applies continuous and stable pressure to the rock wool, and achieves reliable fixation.

[0056] The specific implementation process is as follows: During the descent of the movable box 7, the limiting plate 52 contacts the rock wool surface before the cutting saw 6. As the movable box 7 continues to descend, the movable rod 51 slides upward relative to the movable box 7, and the spring force of the buffer spring 53 increases with the amount of compression. The spring force of the buffer spring 53 is transmitted to the rock wool through the limiting plate 52, pressing the rock wool firmly onto the worktable 1. At this time, the spring is in a slightly compressed state, which ensures the fixing effect while avoiding excessive compression that could damage the rock wool. During the cutting process, the limiting plate 52 always applies stable pressure to the rock wool to prevent it from shifting due to the reciprocating motion of the cutting saw 6. After the cutting is completed, the movable box 7 rises, the buffer spring 53 elastically resets, and pushes the limiting plate 52 to rise synchronously with the movable box 7, detaching it from the rock wool surface. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0057] Example 6:

[0058] This embodiment further defines the structure of the mounting frame 2 based on the above embodiment, such as... Figures 1-3 As shown, guide rails 8 are fixedly connected to both sides of the inner wall of the mounting frame 2. Guide grooves 9, adapted to the guide rails 8, are provided on corresponding positions on both sides of the movable box 7. The guide rails 8 and guide grooves 9 are in sliding engagement. The guide rails 8 on both sides of the inner wall of the mounting frame 2 are protruding structures, while the guide grooves 9 on both sides of the movable box 7 are matching groove structures. The two form a sliding pair, restricting the lateral displacement of the movable box 7. The symmetrically distributed guide rails 8 and guide grooves 9 can balance the lateral force during the lifting and lowering of the movable box 7, preventing it from tilting or jamming due to center of gravity shift or cutting reaction force, ensuring smooth lifting and lowering movement.

[0059] The specific implementation process is as follows: When the movable box 7 is raised or lowered, the guide grooves 9 on both sides slide along the guide rails 8 on the inner wall of the mounting frame 2. The guide rails 8 are embedded in the guide grooves 9, restricting the horizontal displacement of the movable box 7. When the cutting saw 6 performs cutting operations, the reaction force of the rock wool on the saw blade will generate a lateral force. The cooperation between the guide rails 8 and the guide grooves 9 can counteract this lateral force and prevent the movable box 7 from shaking. The guide structure reduces the friction area between the movable box 7 and the mounting frame 2, reduces the resistance of the lifting movement, makes the lifting of the movable box 7 smoother, and reduces mechanical wear. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0060] Example 7:

[0061] This embodiment, based on the above embodiment, further adds scale lines. The upper surface of the worktable 1 is provided with scale lines for marking the cutting length of the rock wool. The scale lines extend along the reciprocating motion direction perpendicular to the cutting saw 6. The scale lines on the worktable 1 provide the operator with an intuitive length reference. Since they extend along the direction perpendicular to the reciprocating motion of the cutting saw 6, which is the feed direction of the rock wool, the cutting position of the rock wool can be directly marked, realizing fixed-length cutting.

[0062] The specific implementation process is as follows: The operator, based on the required cutting length of the rock wool, aligns one end of the rock wool with the corresponding scale value, referring to the scale lines on workbench 1. The position of the rock wool is adjusted so that the cutting line coincides with the scale mark, ensuring that the length of the rock wool after cutting meets the requirements. The equipment is then started to complete the cutting. The presence of the scale lines reduces errors from manual measurement and improves dimensional consistency during batch cutting. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0063] Example 8:

[0064] This embodiment, based on the above embodiment, further adds a protective cover. A protective cover is fitted over the outside of the saw blade of the cutting saw 6. The protective cover is fixedly connected to the top of the cutting saw 6, and the bottom of the protective cover has an opening for the saw blade to extend out. The protective cover is fixedly connected to the top of the cutting saw 6 and moves synchronously with the saw blade. Its bottom opening only allows the working part of the saw blade to extend and contact the rock wool; the non-working part is blocked by the cover. The protective cover can block rock wool debris that splashes during cutting, protecting the operator from injury, and at the same time preventing external debris from contacting the saw blade and affecting cutting accuracy.

[0065] The specific implementation process is as follows: When the cutting saw 6 is working, both the reciprocating and lifting movements of the saw blade occur within the protective cover, with only the saw blade at the bottom opening contacting the rock wool. Rock wool debris generated during cutting is blocked by the protective cover, preventing it from splashing in all directions. When operators are working near the equipment, the protective cover prevents their limbs from accidentally contacting the high-speed moving saw blade. The protective cover rises and falls synchronously with the cutting saw 6, always maintaining its shielding over the saw blade, ensuring effective protection throughout the entire cutting process. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0066] It is understood that the working principle and working process of the rock wool cross-cutting equipment structure according to one embodiment of the present utility model, such as the workbench 1 and the cutting saw 8, are existing technologies and are well known to those skilled in the art, and will not be described in detail here.
