Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock wool board processing, and particularly relates to a feeding and conveying device for rock wool board processing. BACKGROUND

[0002] Rock wool is an inorganic material made of basalt, diabase and other natural minerals as main raw materials, fibers made by high-temperature melting through centrifugal process, and a proper amount of binder and solidification forming. It has excellent fireproof performance (A-grade non-combustible), excellent heat and sound insulation effect, and high compressive strength and long durability, and is widely used in building external wall insulation system, roof insulation layer, fireproof isolation belt, industrial equipment insulation structure and ship cabin partition, and other fields with high safety and energy saving requirements.

[0003] In the production process of rock wool board, the pre-arranged rock wool blocks need to be transferred to the processing conveying belt. This process is usually completed by a rock wool feeding machine. The feeding machine inserts the tines into the rock wool block to achieve grabbing and transferring. However, since different specifications of rock wool boards correspond to different sizes of rock wool blocks, and multiple closely fitted rock wool blocks need to be transported at the same time during feeding, the tines are easily aligned with the edge area of the rock wool block when positioning. When the tines are inserted into the edge part, the local stress is concentrated, which easily causes damage to the edge of the rock wool block, resulting in fragmentation or falling. This physical damage not only affects the overall integrity of the rock wool block, but also reduces the density uniformity and structural consistency of the subsequent pressed board, thereby weakening the mechanical properties and thermal insulation effect of the final rock wool board, and adversely affecting the product quality stability. SUMMARY

[0004] In order to overcome the shortcomings mentioned in the background art, the present application provides a feeding and conveying device for rock wool board processing.

[0005] Technical scheme: A feeding and conveying device for rock wool board processing, comprising a supporting carriage, a sliding lifting module slidingly connected to the supporting carriage, a supporting frame fixedly connected to the lifting end of the sliding lifting module, and a grabbing module symmetrically distributed on the supporting frame. The grabbing module comprises symmetrically distributed first driving members, the fixed parts of the symmetrically distributed first driving members are rotationally connected to the supporting frame, the supporting frame is rotationally connected to a deflection rod rotationally connected to the telescopic ends of the symmetrically distributed first driving members, the deflection rod is provided with an adjusting shaft, and a plurality of fixed claw groups are spline-connected to the adjusting shaft.

[0006] More preferably, the plurality of fixed claw groups on the same adjusting shaft are rotationally connected to a telescopic frame, and the telescopic frame is used to make the distance between any two adjacent fixed claw groups in the corresponding plurality of fixed claw groups the same.

[0007] More preferably, the fixing claw groups at both ends of the adjusting shaft are threadedly connected with locking bolts for pressing the adjusting shaft to fix the fixing claw groups.

[0008] More preferably, the deflection rod is spline-connected with the adjusting shaft for adjusting the positions of all the fixing claw groups.

[0009] More preferably, the support frame is fixedly connected with a second driving member, the telescopic end of the second driving member is fixedly connected with a connecting frame, and all the adjusting shafts are limitingly rotationally connected with the connecting frame.

[0010] More preferably, the fixing claw group is slidingly connected with two single claws symmetrically distributed.

[0011] More preferably, the two single claws on the same fixing claw group are provided with elastic members for applying opposite forces to the two single claws.

[0012] More preferably, the fixing claw group is provided with two sliding grooves symmetrically distributed, the single claw is fixedly connected with a clamping block, and the clamping block slides in the corresponding sliding groove.

[0013] More preferably, the rotation connection between the telescopic frame and the fixing claw group is located at the middle part of the fixing claw group, and the rotation connection between the telescopic frame and the fixing claw group is fixedly connected with a pressing block for limiting the two adjacent single claws.

[0014] More preferably, the outer contour of the pressing block has two arc surfaces symmetrically distributed, and the arc surfaces gradually approach the rotation axis of the pressing block from one side to the other side.

[0015] Compared with the prior art, the present application has the following advantages: 1. The present application fixes the middle side of the corresponding rock wool block by the freely sliding fixing claw groups, so that the fixing claw groups are in the centered state relative to the rock wool block, and the edge position of the rock wool block is not damaged, ensuring the integrity of the shape of the rock wool block.

[0016] 2. The second driving member drives the movement of the fixing claw groups, so that the fixing claw groups in the working state are in the centered state relative to the support frame, ensuring that the support frame is uniformly and stably stressed during the transfer process, and reducing the maintenance frequency of the support frame.

[0017] 3. When the distance between the two adjacent fixing claw groups is reduced, the single claws on both sides of the fixing claw group move synchronously and oppositely, ensuring the distance between the single claw and the edge of the rock wool block, reducing the probability of damage to the rock wool block by the single claw, and ensuring the integrity of the shape of the rock wool block.

[0018] 4. By simultaneously causing the two single claws to deflect upwards around the fixed claw group during their opposing movements, the insertion depth of the two single claws into the rock wool block is reduced, further reducing the probability of the rock wool block falling off at the edge and ensuring the integrity of the rock wool block's shape.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0028] During the production of rock wool boards, neatly stacked rock wool blocks need to be transferred to a processing conveyor belt. Typically, a feeding machine uses rakes inserted into the rock wool blocks to grasp them. Because different specifications of rock wool boards correspond to different sizes of rock wool blocks, and multiple tightly fitted blocks are often handled simultaneously during feeding, the rakes tend to align with the edges of the rock wool blocks. When the rakes insert into the edge area, localized stress concentration can easily cause edge damage, leading to breakage or material detachment, affecting the integrity of the rock wool blocks and consequently reducing the quality of subsequent molding.

[0029] Example 1

[0030] This embodiment provides a material conveying device for processing rock wool boards, used for transferring rock wool blocks.

[0031] like Figures 1-5 As shown, the system includes a support slide 1, a sliding lifting module 2 slidably connected to the support slide 1, the sliding lifting module 2 consisting of an electric slider and a lifting device, and a support frame 3 fixedly connected to the lifting end of the lifting device of the sliding lifting module 2. The sliding lifting module 2 is used to drive the support frame 3 to slide left and right along the support slide 1, and can also move up and down. The support frame 3 is provided with two symmetrically distributed gripping modules, which are located on the front and rear sides of the support frame 3 respectively. The gripping module includes two symmetrically distributed first driving members 4, which are located on the left and right sides of the support frame 3 respectively. The fixed parts of the two symmetrically distributed first driving members 4 are rotatably connected to the support frame 3. The support frame 3 is rotatably connected to a deflection rod 5, which is rotatably connected to the telescopic ends of the corresponding two first driving members 4. The deflection rod 5 is provided with an adjusting shaft 6, and the connection relationship between the deflection rod 5 and the adjusting shaft 6 is fixed. However, this embodiment is limited to the present embodiment. The adjusting shaft 6 is splined with several fixed claw groups 7. In this embodiment, the fixed claw group 7 consists of three equally spaced rake claws and a sliding cylinder. The number of fixed claw groups 7 can be freely set. The upper part of the several fixed claw groups 7 on the same adjusting shaft 6 is rotatably connected to a telescopic frame 8. The telescopic frame 8 is used to ensure that the distance between any two adjacent fixed claw groups 7 is the same. The several fixed claw groups 7 are respectively fixed to the corresponding rock wool blocks. The fixing position of the several fixed claw groups 7 on the rock wool blocks is located on the middle side of the rock wool blocks. The fixed claw groups 7 will not damage the edge position of the rock wool blocks, ensuring the integrity of the rock wool block shape. The fixed claw groups 7 at both ends of the adjusting shaft 6 are threaded with locking bolts 9. The locking bolts 9 are used to press the adjusting shaft 6 to fix the fixed claw groups 7. In the initial state, the locking bolts 9 lock the corresponding fixed claw groups 7.

[0032] Working principle: before the rock wool is needed to be fed and processed, the staff rotates the locking bolt 9 on the left side of the two fixed jaw groups 7 of the support frame 3, so that the locking bolt 9 is released from the extrusion of the adjusting shaft 6, and then the locking bolt 9 is fixed on the left side of the two fixed jaw groups 7. At this moment, the left two fixed jaw groups 7 can slide freely along the adjacent adjusting shaft 6, and then the staff pulls the left two fixed jaw groups 7 in turn, so that the left fixed jaw group 7 slides along the adjacent adjusting shaft 6. The left fixed jaw group 7 drives several fixed jaw groups 7 to slide along the adjacent adjusting shaft 6 through the telescopic frame 8. In this way, the distance between the middle of the two adjacent fixed jaw groups 7 is the same as the width of the rock wool block, and then the left fixed jaw group 7 is stopped from sliding. Then the locking bolt 9 is rotated again, so that the locking bolt 9 is rotated into the adjacent fixed jaw group 7 and contacts with the adjusting shaft 6, and the adjustment of several fixed jaw groups 7 is completed.

[0033] When the fixed jaw group 7 is adjusted, the staff starts the sliding lifting module 2, and the sliding lifting module 2 drives the support frame 3 to slide along the support slide 1. The support frame 3 moves to the upper side of the rock wool block, and the fixed jaw group 7 is located at the corresponding middle of the rock wool block. Then the sliding lifting module 2 stops sliding, and then the sliding lifting module 2 drives the support frame 3 on it to move downward until the fixed jaw group 7 is in contact with the upper side of the rock wool block. Then the sliding lifting module 2 no longer drives the support frame 3 to move downward. At this moment, all the first driving parts 4 are started, and the telescopic end of the first driving part 4 drives the corresponding deflection rod 5 to rotate along the support frame 3. The deflection rod 5 drives the fixed jaw group 7 on it to deflect through the adjusting shaft 6, so that several fixed jaw groups 7 are deflected and inserted into the middle of the corresponding rock wool block, so as to complete the fixation of the rock wool block. Then the sliding lifting module 2 drives several rock wool blocks to move upward synchronously through the support frame 3, the deflection rod 5, the adjusting shaft 6 and the fixed jaw group 7. When the support frame 3 moves to the initial height, it stops. Then the sliding lifting module 2 slides along the support slide 1, so that the rock wool block on it moves to the upper side of the conveying belt.

[0034] When the rock wool block moves to the upper side of the conveying belt, the sliding lifting module 2 stops moving and drives the support frame 3 to move downward. In this way, it stops when the rock wool block is about to contact the conveying belt. Then the telescopic end of all the first driving parts 4 resets and drives the deflection rod 5 to reset the deflection, so that all the fixed jaw groups 7 are released from the fixed state of the rock wool plate. At this moment, the rock wool plate falls onto the conveying belt, and then the above steps are continuously repeated to continuously feed the rock wool block to the conveying belt. In this way, the feeding of the rock wool block is stopped. Through the fixation of several fixed jaw groups 7 to the corresponding rock wool block respectively, and the fixed position of the fixed jaw group 7 to the rock wool block is located at the middle side of the rock wool block, so that the fixed jaw group 7 will not damage the edge position of the rock wool block, and the integrity of the shape of the rock wool block is ensured.

[0035] Example 2

[0036] The embodiment provides a feeding and conveying device for rock wool board processing, which is further improved on the basis of embodiment 1.

[0037] When the rock wool blocks are transported, the models of the rock wool blocks spliced into the rock wool board are different, so that the width, thickness and splicing quantity of the rock wool blocks are different, when the quantity of the rock wool blocks changes from odd to even, the distribution of the rock wool blocks is changed synchronously, that is, the rock wool blocks are not in the centered state relative to the support frame 3, and when the rock wool blocks are transported, the support frame 3 is subjected to uneven stress, and after long-time use, the support frame 3 is subjected to eccentric wear.

[0038] As shown in Figure 2 , the deflection rod 5 is connected with the adjusting shaft 6 in the form of spline connection, the adjusting shaft 6 can slide along the deflection rod 5, that is, the adjusting shaft 6 drives synchronous movement of all the fixing claw groups 7 on the adjusting shaft 6, for adjusting the positions of all the fixing claw groups 7, the right side of the support frame 3 is fixedly connected with a second driving member 201, the telescopic end of the second driving member 201 is fixedly connected with a connecting frame 202, all the adjusting shafts 6 are limitingly rotationally connected with the connecting frame 202, the second driving member 201 can independently modify the positions of all the adjusting shafts 6 through the connecting frame 202, and then synchronously change the fixing positions of the fixing claw groups 7 on the rock wool blocks, so that the several fixing claw groups 7 in the working state are in the centered state relative to the support frame 3, the stress on the support frame 3 is uniform and stable during the transportation process, and the maintenance frequency of the support frame 3 is reduced.

[0039] Working principle: after the adjustment of the fixing claw groups 7 is completed, the workers determine the fixing claw groups 7 that need to work according to the quantity of the rock wool blocks, and Figure 2 five fixing claw groups 7 are shown in the middle, and the carrying quantity of the rock wool blocks is four, since the quantity of the fixing claw groups 7 is more than the quantity of the rock wool blocks, no matter whether the workers select the right four or the left four fixing claw groups 7 to fix the rock wool blocks, the several rock wool blocks are in the eccentric state relative to the support frame 3, so after the adjustment of the fixing claw groups 7 is completed, the second driving member 201 is started, the telescopic end of the second driving member 201 drives synchronous movement of the two adjusting shafts 6 through the connecting frame 202, the adjusting shaft 6 drives synchronous movement of the several fixing claw groups 7 on the adjusting shaft 6, the four fixing claw groups 7 for fixing the rock wool blocks are in the centered state relative to the support frame 3, then the second driving member 201 is stopped, and the several fixing claw groups 7 are driven to move together through the second driving member 201, so that the several fixing claw groups 7 in the working state are in the centered state relative to the support frame 3, the stress on the support frame 3 is uniform and stable during the transportation process, and the maintenance frequency of the support frame 3 is reduced.

[0040] Embodiment 3

[0041] The embodiment provides a feeding and conveying device for rock wool board processing, which is further improved on the basis of embodiment 2.

[0042] When this device is used to fix a rock wool block with a small width, the distance between the fixing position of the fixing claw group 7 and the edge of the rock wool block becomes smaller. The fixing claw group 7 will still cause damage to the edge of the rock wool block, thus affecting the shape stability of the rock wool block.

[0043] like Figures 3-7 As shown, in this embodiment, the fixing claw assembly 7 consists of a rake claw and a sliding cylinder, with the rake claw located in the middle of the sliding cylinder. The fixing claw assembly 7 is slidably connected to two symmetrically distributed single claws 301, which replace the original rake claw to fix the rock wool block. Figure 3 The state shown represents the maximum distance between the two fixed claw groups 7, i.e., the two symmetrically distributed single claws 301 in the initial state are located at both ends of the adjacent fixed claw groups 7. An elastic element 302 is provided between the two single claws 301 on the same fixed claw group 7. The elastic element 302 is a tension spring and is always in a stretched state. The elastic element 302 is used to apply a counterforce to the two single claws 301, causing the two single claws 301 to slide in opposite directions along the fixed claw group 7, maintaining the distance between the single claw 301 and the edge of the rock wool block. The fixed claw group 7 is provided with two symmetrically distributed sliding grooves 303. A locking block 304 is fixedly connected to the inner side of the single claw 301. The locking block 304 slides in the corresponding sliding groove 303. When the two single claws 301 move in opposite directions, the locking block 304 drives the adjacent single claw 301 to deflect upward, which is used to reduce the insertion depth of the single claw 301 into the rock wool block. When the distance between the two adjacent fixed claw groups 7 decreases, the rotational connection between the telescopic frame 8 and the fixed claw group 7 rotates counterclockwise (towards...). Figure 6 (Described from a top view) When the distance between two adjacent fixed claw groups 7 increases, the rotational connection between the telescopic frame 8 and the fixed claw group 7 rotates clockwise. The rotational connection between the telescopic frame 8 and the fixed claw group 7 is located in the middle of the fixed claw group 7. A pressing block 305 is fixedly connected to the rotational connection between the telescopic frame 8 and the fixed claw group 7. When adjusting the distance between two adjacent fixed claw groups 7, the rotational connection between the telescopic frame 8 and the fixed claw group 7 will drive the pressing block 305 to rotate synchronously. The pressing block 305 is used to limit the two adjacent single claws 301. The outer contour of the pressing block 305 has two symmetrically distributed arc surfaces 3051. The arc surfaces 3051 gradually approach the rotation axis of the pressing block 305 from one side to the other. The rotation of the pressing block 305 drives the arc surfaces 305 to rotate synchronously, changing the contact position between the single claw 301 and the arc surface 3051, thereby realizing the equidistant opposing movement of the two single claws 301.

[0044] Working principle: When the distance between two adjacent fixed claw groups 7 is reduced, the connection between the telescopic frame 8 and the fixed claw will rotate counterclockwise (towards...). Figure 6When the two single claws 301 move towards each other, the single claw 301 drives the internal clamping block 304 to move synchronously, at this moment, the clamping block 304 slides along the adjacent sliding groove 303, so that the clamping block 304 drives the single claw 301 to deflect upwards. Since the deflection directions of the two single claws 301 are consistent, i.e., the elastic members 302 between the two single claws 301 rotate synchronously, but do not twist, so as to reduce the insertion depth of the two single claws 301 to the rock wool block, further reduce the probability of falling off at the edge of the rock wool block, and ensure the integrity of the shape of the rock wool block.

[0045] When the two single claws 301 move towards each other, the single claw 301 drives the internal clamping block 304 to move synchronously, at this moment, the clamping block 304 slides along the adjacent sliding groove 303, so that the clamping block 304 drives the single claw 301 to deflect upwards. Since the deflection directions of the two single claws 301 are consistent, i.e., the elastic members 302 between the two single claws 301 rotate synchronously, but do not twist, so as to reduce the insertion depth of the two single claws 301 to the rock wool block, further reduce the probability of falling off at the edge of the rock wool block, and ensure the integrity of the shape of the rock wool block.

[0046] The above has carried out the detailed introduction to the present application, the principle and the implementation mode of the present application have been set forth by applying the specific example in this paper, the above embodiment is only used for helping understanding the method of the present application and its core idea, simultaneously, for the general technical personnel of the field, according to the idea of the present application, in the specific implementation mode and the application range, will have the change, the above-mentioned, the content of the specification should not be understood as the limitation of the present application.
