Description

Technical Field

[0001] The utility model relates to the field of vibration molding, in particular to a vibration device and an artificial stone press comprising the vibration device. Background Art

[0002] Artificial quartz slab presses are equipped with vibration motors arranged in multiple groups within the ram. Each group of vibration motors is connected in series using couplings to ensure synchronized operation. The excitation force generated by the vibration motors is the driving force for the ram's reciprocating pressing motion. This excitation force is generated by the rotation of the eccentric blocks driven by the main shaft. The excitation force can be varied by changing the angle, radius, or mass of the inner and outer eccentric blocks at either end of the main shaft. In the actual production of artificial quartz slabs, the excitation force of the series-connected vibration motors must be properly distributed to achieve optimal pressing results due to factors such as the type of raw material, material distribution conditions, and structural layout. In existing artificial quartz slab presses, the movable eccentric blocks of the series-connected vibration motors in the same group rotate in unison around the main shaft, creating the same angle with the fixed eccentric block. This ensures that each vibration motor receives the same percentage of excitation force. However, this adjustment method, which involves synchronously changing the angle of the eccentric blocks, fails to achieve a reasonable distribution of the excitation force. Some artificial stone slab presses solve this problem by increasing or decreasing the mass of the counterweight block on the eccentric block and changing the eccentric radius. However, this problem has disadvantages such as complex manufacturing, large amount of materials, high cost, low efficiency, and insecurity, and is not conducive to the precise control and efficient operation of the press.

[0034] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0035] See also Figure 1-11 The utility model discloses a vibration device, which includes a plurality of vibration mechanisms 1 and a coupling mechanism, wherein two adjacent vibration mechanisms 1 are connected by the coupling mechanism.

[0036] The vibration mechanism 1 includes a vibration body 11 and a rotating shaft 12 arranged on the vibration body 11. A fixed eccentric block 13 and a movable eccentric block 14 are sleeved on the rotating shaft 12. The fixed eccentric block 13 and the rotating shaft 12 are relatively fixed in the circumferential direction, and the movable eccentric block 14 can rotate around the rotating shaft 12.

[0037] The coupling mechanism includes a coupling assembly, which includes an offset adjustment member 2 and a coupling member 3. The offset adjustment member 2 is disposed at the end of a rotating shaft 12 and is relatively fixed to the rotating shaft 12 in the circumferential direction. The offset adjustment member 2 and the coupling member 3 are relatively movable in the circumferential direction. The rotating shaft 12, the offset adjustment member 2, and the coupling member 3 are coaxially disposed.

[0038] The fixed eccentric mass 13 is rotated by a first preset angle by the deflection adjusting member 2 , and the movable eccentric mass 14 is rotated by a second preset angle in the opposite direction around the rotating shaft 12 , so that a preset angle is formed between the fixed eccentric mass 13 and the movable eccentric mass 14 .

[0039] The vibration device of the utility model utilizes an adjustment member that can rotate relative to the coupling member, thereby driving the rotation shaft to rotate, and then the rotation shaft drives the fixed eccentric block to rotate, so that the fixed eccentric block rotates by a first preset angle. Then, the connection between the movable eccentric block and the rotation shaft is loosened, so that the movable eccentric block rotates around the rotation shaft in the opposite direction by a second preset angle, so that a preset angle is formed between the fixed eccentric block and the movable eccentric block to obtain a corresponding excitation force. In the artificial stone press, the vibration mechanisms at different positions of the same group of pressure heads connected in series can adjust the angle between the fixed eccentric block and the movable eccentric block through this adjustment method to obtain different percentages of excitation force, so that the excitation force is reasonably distributed and synchronously excited to achieve the best pressing state. In addition, the structure is simple, the adjustment is convenient, the cost is low, the efficiency is high, and the installation is high, which is also conducive to the precise control and efficient operation of the press.

[0040] Preferably, the vibration mechanism 1 is a vibration motor.

[0041] Specifically, such as Figure 3 、 6 As shown, the shaft 12 is fixed relative to the circumference of the deflection adjusting member 2 via a flat key 15. The end surface of the shaft 12 is provided with an end groove, the deflection adjusting member 2 is provided with an axis groove 23, and the bottom wall of the axis groove 23 is provided with a key groove 24. The flat key 15 is respectively embedded in the end groove and the key groove 24.

[0042] Preferably, if Figure 8-9 As shown, the alignment groove 21 is provided on the deflection adjusting member 2, and the alignment platform 31 is provided on the coupling 3. The alignment platform 31 is embedded in the alignment groove 21 to ensure coaxial alignment between the deflection adjusting member 2 and the coupling 3. Specifically, the alignment groove 21 is provided on the side of the deflection adjusting member 2 facing the coupling 3, and the alignment platform 31 is provided on the side of the coupling 3 facing the deflection adjusting member 2. The coordination of the alignment groove and the alignment platform allows the deflection adjusting member and the coupling to be automatically and quickly aligned, ensuring coaxiality between the two, and facilitating easy and efficient installation.

[0043] More preferably, if Figure 8-9 As shown, the inner wall of the alignment groove 21 is provided with a first tapered surface 211, and the outer wall of the alignment platform 31 is provided with a second tapered surface 311. The first tapered surface 211 and the second tapered surface 311 are arranged in close contact with each other. The arrangement of the tapered surfaces further enables automatic and rapid alignment of the alignment member and the coupling. The close contact between the first and second tapered surfaces further ensures the coaxiality of the alignment member and the coupling and prevents radial relative movement of the alignment member and the coupling.

[0044] Preferably, if Figure 7-10 As shown, the deflection adjusting member 2 is provided with a plurality of deflection adjusting holes 22, and the deflection adjusting holes 22 are arranged at intervals along the circumference of the deflection adjusting member 2; the coupling member 3 is provided with a plurality of coupling holes 32, and the coupling holes 32 are arranged at intervals along the circumference of the coupling member 3; the positions of the deflection adjusting holes 22 and the coupling holes 32 are relatively fixed, so that the deflection adjusting member 2 and the coupling member 3 are fixedly connected. Particularly, the deflection adjusting holes 22 and the coupling holes 32 are arranged correspondingly. More preferably, the deflection adjusting holes 22 are arranged at intervals and evenly distributed along the circumference of the deflection adjusting member 2, and the coupling holes 32 are arranged at intervals and evenly distributed along the circumference of the coupling member 3. Specifically, the deflection adjusting holes 22 are screw holes, and the coupling holes 32 are through holes, and the positions of the deflection adjusting holes 22 and the coupling holes 32 can be relatively fixed by bolts, so that the deflection adjusting member and the coupling member are fixedly connected. Rotating the deflection adjustment member allows the deflection adjustment holes to connect to different coupling holes. That is, the deflection adjustment member can rotate relative to the coupling member, causing the fixed eccentric mass to rotate by the same angle via the rotating shaft. More specifically, the angle between two adjacent deflection adjustment holes 22 is 15°, and the angle between two adjacent coupling holes 32 is 15°.

[0045] Specifically, such as Figure 5-6As shown, the vibration mechanism includes a first vibration mechanism 1a and a second vibration mechanism 1b, which are connected by a coupling mechanism; the coupling assembly includes a first coupling assembly and a second coupling assembly, the first coupling assembly includes a first deflection adjusting member 2a and a first coupling member 3a, and the second coupling assembly includes a second deflection adjusting member 2b and a second coupling member 3b; the first vibration mechanism 1a, the first deflection adjusting member 2a, the first coupling member 3a, the second coupling member 3b, the second deflection adjusting member 2b, and the second vibration mechanism 1b are connected in sequence, and the first coupling member 3a and the second coupling member 3b are relatively fixed in circumferential direction. Therefore, the present invention enables multiple vibration mechanisms to be synchronously excited through the coupling mechanism.

[0046] Preferably, if Figure 1 、 10 As shown, the coupling 3 is provided with limit platforms 33 spaced along the circumference of the coupling 3. Specifically, the limit platform 33 of the first coupling 3a is arranged between the limit platforms 33 of the two adjacent second couplings 3b, so that the circumference of the first coupling 3a and the second coupling 3b are relatively fixed. In other words, the limit platforms of the first coupling and the second coupling are staggered, that is, the limit platform of the first coupling is placed between the two adjacent limit platforms of the second coupling, and the limit platform of the second coupling is placed between the two adjacent limit platforms of the first coupling. The first coupling and the second coupling are driven by the limit platforms to rotate synchronously, that is, the two adjacent vibration mechanisms rotate synchronously, and synchronous excitation is achieved.

[0047] Further, if Figure 3 、 4 As shown in Figures 6 and 11, the coupling mechanism further includes a buffer member 4. A buffer cavity 34 is formed between the adjacent limiting platforms 33 of the first coupling member 3a and the limiting platforms 33 of the second coupling member 3b, and the buffer member 4 is embedded in the buffer cavity 34. The provision of the buffer member can prevent collision between the two adjacent limiting platforms, reduce friction, and also provide shock absorption and buffering effects.

[0048] Preferably, if Figure 4 、 11 As shown, the buffer member 4 includes a connecting portion 41 and a plurality of buffer portions 42 disposed on the connecting portion 41. The buffer portions 42 are embedded in the buffer cavity 34. The connecting portion 41 is annular, and the buffer portions 42 are evenly spaced along the circumference of the connecting portion 41. Each buffer portion is disposed in a corresponding buffer cavity, making the connection structure between the first coupling and the second coupling compact and reliable.

[0049] Preferably, the buffer member 4 is a polyurethane elastomer.

[0050] It should be noted that the fixed and movable eccentric masses are symmetrically positioned at either end of the rotating shaft of the same vibration mechanism. The angle between the fixed and movable eccentric masses must be identical. As the shaft rotates, the movable eccentric mass clamps the shaft and rotates with it. To adjust the angle between the fixed and movable eccentric masses, loosen the bolts on the movable eccentric mass to allow it to rotate. Once the angle is adjusted, tighten the bolts again. The central plane of symmetry for the fixed and movable eccentric masses within the same vibration mechanism must be identical.

[0051] In the initial state, the fixed eccentric mass 13 and the movable eccentric mass 14 on both ends of the rotating shaft 12 of the two adjacent vibration mechanisms 1 overlap, that is, the angle between the fixed eccentric mass 13 and the movable eccentric mass 14 is 0°. At this time, the excitation force of the two vibration mechanisms 1 is 100% of the maximum excitation force. Figure 5-6 As shown, loosen the connecting bolts of the first deflection adjusting member 2a and the first coupling member 3a, rotate the rotating shaft 12 of the first vibration mechanism 1a, rotate the first deflection adjusting member 2a by one hole position, i.e., 15°, and then loosen the connection between the movable eccentric block and the rotating shaft, and then rotate the movable eccentric blocks 14 at both ends of the rotating shaft 12 of the first vibration mechanism 1a in opposite directions by 30°, so that the angle between the fixed eccentric block 13 and the movable eccentric block 14 of the first vibration mechanism 1a is 30°. At this time, the first vibration mechanism 1a obtains a cos15° (96.6%) exciting force. Similarly, the first adjustment member 2a rotates 2 holes, i.e. 30°, 3 holes, i.e. 45°, 4 holes, i.e. 60°, and 5 holes, i.e. 75°, and the corresponding movable eccentric block 14 rotates 60°, 90°, 120°, and 150° in the opposite direction, i.e. the angle between the fixed eccentric block 13 and the movable eccentric block 14 is adjusted to 60°, 90°, 120°, and 150°, and the first vibration mechanism 1a obtains cos30° (86.6%), cos45° (70.7%), cos60° (50%), and cos75° (25.9%) exciting forces, respectively. In an artificial stone press, the vibration mechanisms at different positions of the same group of press heads connected in series can use this adjustment method to adjust the angle between the fixed eccentric block and the movable eccentric block to obtain different percentages of exciting force, so that the exciting force is reasonably distributed and the excitation is synchronized to achieve the optimal pressing state. In addition, the structure is simple, the adjustment is convenient, the cost is low, the efficiency is high, and the installation is easy, which is also conducive to the precise control and efficient operation of the press.

[0052] Preferably, the first preset angle is 15°, 30°, 45°, 60° or 75°, but not limited thereto. The second preset angle is 30°, 60°, 90°, 120° or 150°, but not limited thereto. Correspondingly, the preset angle is 30°, 60°, 90°, 120° or 150°. It should be noted that, since the rotating shaft drives the movable eccentric mass to rotate together when the fixed eccentric mass is rotated, the fixed eccentric mass and the movable eccentric mass simultaneously rotate by the first preset angle of 15°, 30°, 45°, 60° or 75°. Then, when the connection between the movable eccentric mass and the rotating shaft is released, and the movable eccentric mass rotates in the opposite direction around the rotating shaft by the second preset angle, the second preset angle should be 30°, 60°, 90°, 120° or 150° accordingly. Only in this way can the fixed eccentric block and the movable eccentric block be symmetrically arranged on the original center line, thereby ensuring the stability and reliability of the vibration mechanism operation.

[0053] Correspondingly, the present invention also discloses an artificial stone press, comprising the above-mentioned vibration device. The specific structure of the vibration device is as described above and will not be repeated here.

[0054] The vibration device of the utility model utilizes an adjustment member that can rotate relative to the coupling member, thereby driving the rotation shaft to rotate, and then the rotation shaft drives the fixed eccentric block to rotate, so that the fixed eccentric block rotates in one direction by a first preset angle. Then, the connection between the movable eccentric block and the rotation shaft is loosened, so that the movable eccentric block rotates around the rotation shaft in the opposite direction by a second preset angle, so that a preset angle is formed between the fixed eccentric block and the movable eccentric block to obtain a corresponding excitation force. In the artificial stone press, the vibration mechanisms at different positions of the pressure heads connected in series in the same group can adjust the angle between the fixed eccentric block and the movable eccentric block through this adjustment method to obtain different percentages of excitation force, so that the excitation force is reasonably distributed and synchronously excited to achieve the best pressing state. In addition, the structure is simple, the adjustment is convenient, the cost is low, the efficiency is high, and the installation is high, which is also conducive to the precise control and efficient operation of the press.

[0055] In summary, the utility model provides a vibration device and an artificial stone press including the vibration device, which can reasonably distribute the exciting force and has a simple structure.

[0056] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
