A roller press and method for quartz stone plate raw materials

Abstract

This invention discloses a rolling mill and method for quartz stone slab raw materials, relating to the field of quartz stone raw material rolling. The invention utilizes a liftable pre-compression device installed upstream of the conveyor belt, coupled with a gear and rack linkage structure, to enable two sets of contact rollers to move in opposite directions and perform multi-position extended rolling with adjustable angles during the pre-compression process. This effectively improves the loose state and uneven thickness of the raw material before entering the main rolling process. Simultaneously, the angles of the contact rollers at both ends can be independently adjusted to accommodate quartz stone raw materials with different particle sizes, adhesive contents, and layer thicknesses, improving pre-compression density and uniformity. The pre-compressed material is then further rolled by two sets of rolling mechanisms that can move left and right, forming a graded rolling mode of "pre-compression + main rolling." This not only improves rolling stability and forming quality but also effectively reduces the internal porosity and edge defects of the slabs, enhancing the density, consistency, and subsequent slitting pass rate of the quartz stone slabs.

Description

Technical Field

[0001] This invention relates to the field of quartz stone raw material crushing, and more particularly to a crushing machine and method for quartz stone slab raw materials. Background Technology

[0002] Quartz stone slabs are typically made from quartz sand, quartz powder, and resin adhesives as the main raw materials. After mixing, spreading, and rolling, they are then cured and slit. In existing quartz stone slab production lines, the rolling process often uses a single rolling mechanism to directly roll the raw materials laid on the conveyor belt in one pass. Because the raw materials are prone to uneven thickness, local accumulation, or looseness during the spreading stage, direct rolling can easily cause uneven stress, resulting in significant differences in the internal density of the slabs. This can lead to voids, cracks, or unstable molding at the edges and in localized areas. In addition, traditional rolling devices are mostly fixed structures with limited rolling angles and application positions, making it difficult to effectively adjust them according to the particle size distribution, adhesive content, and spreading state of different quartz stone raw materials. This results in poor adaptability and processing stability. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a rolling mill and method for quartz stone slab raw materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rolling mill for quartz stone slab raw materials, including a support frame, a conveyor belt at the top of the support frame, a lifting mechanism body for lifting and lowering at the top left end of the conveyor belt, a pre-pressing device installed at the upper end of the lifting mechanism body that moves up and down with it, the pre-pressing device being used to pre-press the material passing below, a sliding device body at the front and rear positions of the conveyor belt, and a rolling mechanism at the top of the sliding device body.

[0005] Preferably, the pre-compression device includes a top plate for support and connected to the main body of the lifting mechanism on the back, a first motor located at the top center of the top plate, a rotating disk installed below the top plate and connected to the output shaft of the first motor at the center, a base frame connected to the bottom of the top plate, a limiting rod located at the front end of the base frame, a contact mechanism installed at the front and rear positions of the lower end of the base frame, a rotating shaft connected to the center of the rotating disk, a gear located at the lower end of the rotating shaft, a rack meshing with the left and right ends of the gear, and sliding members located at the front and rear ends inside the base frame, wherein the bottom of the sliding member is in contact with the contact structure.

[0006] Preferably, the limiting rod is threadedly connected to the base frame.

[0007] Preferably, the base frame has sliding grooves at both the front and rear ends, and sliding components are movably embedded inside the sliding grooves.

[0008] Preferably, the front sliding member corresponds to the limiting rod, and the right end of the limiting rod extends into the front sliding groove.

[0009] Preferably, the contact mechanism includes a fixed box connected to the bottom of the sliding member, a support at the bottom of the fixed box, a contact roller installed in the middle of the support, a second motor located at the right end inside the fixed box, a drive gear connected to the bottom output shaft of the second motor, a driven gear meshing with the driven gear, and a connecting shaft located in the middle of the driven gear. The bottom of the connecting shaft passes through the fixed box and connects to the support.

[0010] Preferably, the surface of the contact roller is smooth.

[0011] Preferably, the contact roller is in a movable state within the support.

[0012] The preferred compaction method has the following specific steps:

[0013] S1. Feeding and conveying steps: The mixed quartz stone slab raw material is evenly spread on the conveyor belt through the feeding equipment. The conveyor belt is started so that the quartz stone slab raw material is conveyed to the rolling station along the conveying direction.

[0014] S2. Pre-compression device lowering and contact positioning steps: Start the main body of the lifting mechanism to drive the pre-compression device to move downwards, so that the two sets of contact mechanisms at the bottom of the pre-compression device gradually contact the quartz stone slab raw material on the conveyor belt and form a pre-compression contact state at the set height position.

[0015] S3. Pre-compacting step: Start the first motor. The output shaft of the first motor drives the rotating disk to rotate. The rotating disk drives the rotating shaft to rotate synchronously. The rotating shaft drives the gear to rotate. During the rotation, the gear drives the front and rear racks to produce opposite displacement. The racks drive the two sets of contact mechanisms to slide in opposite directions along the slide groove in the base frame through the sliding parts. This allows the two sets of contact rollers to pre-compact the quartz stone slab raw material in opposite directions, thereby initially compacting and flattening the raw material.

[0016] S4. Multi-angle extension pre-compression step: During the pre-compaction process, the second motors in the two sets of contact mechanisms are started respectively. The second motors drive the drive gear to rotate, and the drive gear meshes with the driven gear, causing the driven gear to drive the connecting shaft to rotate, thereby driving the support to adjust the angle, so that the contact rollers produce rotational pre-compression at different angles, realizing multi-position and multi-directional extension and compaction of the quartz stone slab raw material; the angles of the contact rollers at both ends can be controlled independently to adapt to the differences in the laying state of the raw material;

[0017] S5. Main rolling step: After the pre-rolling is completed, the quartz stone slab raw material continues to be conveyed forward by the conveyor belt to the bottom of the rolling mechanism. The two sets of rolling mechanisms are started to roll the raw material into shape. At the same time, the main body of the sliding device is started so that the rolling mechanism can be adjusted to the left and right as needed to ensure uniform rolling force and improve the overall density and forming stability of the slab.

[0018] S6. Discharge and subsequent processing steps: After the main crushing is completed, the quartz stone slab raw material continues to be conveyed to the right end of the conveyor belt and enters the slitting equipment for automatic slitting, or is slitting manually to complete the crushing process of the quartz stone slab raw material.

[0019] The beneficial effects of this invention are:

[0020] This invention, by setting a liftable pre-compression device upstream of the conveyor belt and cooperating with a gear and rack linkage structure, enables two sets of contact rollers to move towards each other and extend and roll at multiple positions with adjustable angles during the pre-compression process. This effectively improves the loose state and uneven thickness of the raw materials before entering the main rolling process. At the same time, the angles of the contact rollers at both ends can be adjusted independently to adapt to quartz raw materials with different particle sizes, adhesive contents, and material thicknesses, improving the pre-compression density and uniformity. The pre-compressed material is then further rolled by a double-set rolling mechanism that can move left and right, forming a graded rolling mode of "pre-rolling + main rolling". This not only improves rolling stability and forming quality but also effectively reduces the internal porosity and edge defects of the slab, improving the density, consistency, and subsequent slitting qualification rate of the quartz slab, making it suitable for continuous and high-efficiency production.

[0029] Please see Figure 1 This invention provides a rolling mill for quartz slab raw materials, including a support frame 1 for support, a conveyor belt 2 installed on the top of the support frame 1, a lifting mechanism body 6 installed on the top left end of the conveyor belt 2, a pre-compression device 3 installed at the bottom of the lifting mechanism body 6, the pre-compression device 3 moving up and down with the lifting mechanism body 6 to pre-compress the material passing under the conveyor belt 2, and sliding device bodies 4 installed at the front and rear ends of the conveyor belt 2, two sets of rolling mechanisms 5 installed on the top of the sliding device bodies 4, the rolling mechanisms 5 moving left and right with the sliding device bodies 4 to roll the pre-compressed material.

[0030] Please see Figure 2-4 The preloading device 3 includes a top plate 31 for support. A first motor 32 is installed at the center of the top of the top plate 31. The four ends of the bottom of the top plate 31 are fixed to the base frame 34 by bolts. The back of both the top plate 31 and the base frame 34 are connected to the main body 6 of the lifting mechanism. A rotating disk 33 is installed at the center of the bottom of the top plate 31. The output shaft of the first motor 32 is connected to the center of the rotating disk 33. A limiting rod 35 is provided at the front end of the base frame 34. The limiting rod 35 is threadedly connected to the base frame 34. A set of contact mechanisms 36 is installed at each of the front and rear ends of the bottom of the base frame 34. The bottom of the contact mechanisms 36 can contact... The material has a rotating shaft 37 installed at the top center of the base frame 34. The top of the rotating shaft 37 is connected to the rotating disk 33, and the lower end of the rotating shaft 37 is connected to the gear 38. Each end of the gear 38 has a set of racks 39 meshing with it. The other end of the racks 39 is locked to the sliding member 310. The base frame 34 has sliding grooves at both the front and rear ends. The sliding member 310 is movably embedded in the sliding groove and can slide along the sliding groove. The bottom of the sliding member 310 is connected to the contact mechanism 36. The left end of the sliding member 310 corresponds to the limiting rod 35. The rear end of the limiting rod 35 extends into the front sliding groove.

[0031] Please see Figure 5-6 The contact mechanism 36 includes a fixed box 361 whose top is connected to the sliding member 310. A support 362 is provided at the bottom of the fixed box 361. A contact roller 363 is rotatably provided at the lower end of the support 362. The surface of the contact roller 363 is smooth. A second motor 364 is provided at the right end inside the fixed box 361. The bottom output shaft of the second motor 364 is connected to a drive gear 365. The left side of the drive gear 365 meshes with a driven gear 366. A connecting shaft 367 is provided in the middle of the driven gear 366. The bottom of the connecting shaft 367 passes through the fixed box 364 and connects to the support 362. The support 362 rotates with the connecting shaft 367 to adjust its angle. The contact roller 363 can rotate inside the support.

[0032] The specific implementation process is as follows:

[0033] When it is necessary to crush the quartz stone slab raw material, it is first fed onto the conveyor belt 2 by the feeding equipment. The conveyor belt 2 is started to transport it to the right end. Then, the lifting mechanism body 6 is started to move the pre-compression device 3 downward. During the movement, the two sets of contact rollers 363 inside the pre-compression device 3 come into contact with the quartz stone slab raw material to pre-crush it. At the same time, the first motor 32 is started to work. The first motor 32 drives the rotating disk 33 to rotate the rotating shaft 37. The rotating shaft 37 then drives the gear 38 to rotate. During the rotation of the gear 38, the rack 39 is engaged. During the displacement process, the sliding part 310 at the bottom moves relative to the two sets of contact mechanisms 36 to achieve crushing. It can also start the second motor 364 to work. The second motor 364 drives the drive gear 365 to rotate, and the drive gear 365 drives the driven gear 366 to rotate. During the rotation of the driven gear 366, the connecting shaft 367 causes the support 362 to adjust its angle, so that the contact roller 363 inside it can also adjust its angle. This allows for multi-position extension of the material passing below. The angles of the contact rollers 363 at both ends can be controlled independently for better pre-crushing.

[0034] After pre-compaction, the material is conveyed to the crushing mechanism 5 for crushing. It can be crushed by two sets of crushing mechanisms 5. At the same time, the sliding device body 4 is activated to adjust the left and right position of the crushing mechanism 5 for stable and efficient crushing. The crushed material is finally moved to the right end and conveyed to the cutting equipment, or it can be cut manually.
