[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In the description of the present utility model, "several" refers to one or more, and "multiple" refers to two or more. If there is a description of "first" or "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Reference Figure 1 As shown, due to the limitation of the installation space of the boat-beating device 1000, the telescopic component 100 and the vibration component 300 can only be arranged in parallel. In the related art, the roller component 200, the buffer component 400 and the vibration component 300 are located in the same vertical direction, and the action line of the telescopic component 100 is parallel to the action line of the roller component 200 and is arranged at intervals. When the force application point of the telescopic component 100 is taken as the origin, the reaction force F of the roller component 200 and the distance L from the reaction force point of the roller component 200 to the origin form a moment, so that the force application point of the telescopic component 100 has a bending moment. During long-term use, the force application point of the telescopic component 100 is long-term subjected to the influence of the bending moment, which makes the force application point of the telescopic component 100 easy to bend or be damaged, affecting the normal use of the boat-beating device 1000 and reducing the boat-beating effect.

[0046] Reference Figures 2 to 4As shown, the first embodiment of the utility model proposes a boat-beating device 1000, including: a telescopic component 100, a roller component 200, a vibration component 300 and N buffer components 400, the telescopic component 100 includes a telescopic part 110 that can be telescoped along a first direction and a connecting plate 120 connected to the telescopic part 110; the roller component 200 includes a fixed plate 210 and a roller 220 distributed along the first direction, the fixed plate 210 and the connecting plate 120 are opposite and spaced apart, the roller 220 is located on the side of the fixed plate 210 away from the connecting plate 120, and along the second direction The first direction is connected to the fixed plate 210, and the second direction intersects the first direction; the vibration component 300 is arranged in parallel with the telescopic component 100 and connected to the fixed plate 210 to vibrate the roller 220; the buffer component 400 connects the fixed plate 210 and the connecting plate 120 along the first direction to buffer the pressure applied to the fixed plate 210 by the telescopic part 110; wherein, the distance from the connection position of the buffer component 400 and the connecting plate 120 to the connection position of the telescopic part 110 and the connecting plate 120 is L, and the force of the buffer component 400 along the first direction is F, and the boat-beating device 1000 satisfies:

[0047]

[0048] It should be noted that, due to the limitation of the installation space of the boat-beating device 1000, the telescopic component 100 and the vibration component 300 are still arranged in parallel to save the installation space in the vertical direction, and the lines of force of the telescopic component 100, the roller component 200 and the buffer component 400 coincide on the same straight line in the vertical direction, so that the telescopic action line of the telescopic component 100 and the reaction line of the roller component 200 are on the same straight line, so as to avoid the telescopic component 100 from being subjected to additional bending moment and improve the stability of the connection position between the telescopic component 100 and the fixed plate 210.

[0049] It should also be noted that the graphite boat equipment includes a frame, a graphite boat 2000 and a boat-beating device 1000, the boat-beating device 1000 is fixedly connected to the top of the frame and is located above the graphite boat 2000, the roller 220 of the roller assembly 200 of the boat-beating device 1000 can be lowered to abut against the top of the graphite boat 2000, the graphite boat 2000 in the frame can move along the third direction, and when the graphite boat 2000 moves, the roller 220 in contact with the top of the graphite boat 2000 rotates. Among them, the first direction, the second direction and the third direction are perpendicular to each other.

[0050] In this embodiment, the telescopic assembly 100 is a telescopic cylinder or a lead screw slider structure. When the telescopic assembly 100 is a telescopic cylinder, the telescopic assembly 100 includes a driving unit 130, a telescopic rod with one end connected to the driving unit 130, and a telescopic unit 110 at the other end of the telescopic rod. The driving unit 130 is connected to an air source. Under the pressure control of the air source, the driving unit 130 drives the telescopic rod to telescope along a first direction, thereby driving the telescopic unit 110 to telescope along the first direction, so as to drive the roller 220 of the roller assembly 200 to abut against the top of the graphite boat 2000. The driving unit 130 is fixedly connected to the top of the frame through a mounting plate. As another embodiment, when the telescopic assembly 100 is a screw slider structure, the telescopic assembly 100 includes a motor, a rotating screw connected to the motor, a slider threadedly sleeved on the rotating screw, and a telescopic part 110 connected to the slider. The motor drives the rotating screw to rotate around its axis, so that the slider moves along the axis of the rotating screw and drives the telescopic part 110 to move along the axis of the rotating screw. The axis of the rotating screw is set along the first direction. The connecting plate 120 is connected to the telescopic part 110 to telescope along the first direction.

[0051] The fixed plate 210 of the roller assembly 200 is a square plate. A roller 220 is arranged on one side of the fixed plate 210 away from the telescopic part 110. The roller 220 is connected to the fixed plate 210 by rotation along the second direction so as to rotate around the second direction. The force applied to the roller 220 by the movement of the graphite boat 2000 is eliminated by rotation, so that the boat-beating device 1000 can remain relatively still with the graphite boat 2000, and the damage of the boat-beating device 1000 caused by the additional force is avoided. Among them, when the first direction is perpendicular to the second direction, the roller 220 is generally cylindrical, so that the outer peripheral surface of the roller 220 can be attached to the top surface of the graphite boat 2000. In addition, when the second direction intersects the first direction and is inclined with the horizontal, the roller 220 can also be in an oblique cone shape, wherein the inclination angle of the oblique cone of the roller 220 is consistent with the inclination angle of the second direction to the horizontal plane, so that the bottom of the outer peripheral surface of the roller 220 can be kept horizontal, and then the outer peripheral surface of the roller 220 can be attached to the top surface of the graphite boat 2000.

[0052] The vibration assembly 300 is arranged in parallel with the telescopic assembly 100 to adapt to the narrow installation space on the frame. The vibration assembly 300 is used to apply a vibration force to the roller 220 along the first direction, so that the roller 220 can vibrate along the first direction, and then apply the vibration force to the graphite boat 2000, so that the graphite boat 2000 vibrates along the first direction, achieving the effect of simulating a person's hand hitting the boat.

[0053] The buffer assembly 400 is arranged between the connecting plate 120 and the fixing plate 210 to buffer the pressure applied by the telescopic assembly 100 to the roller assembly 200. When the telescopic assembly 100 drives the roller assembly 200 to abut against the top of the graphite boat 2000, the buffer assembly 400 is located between the telescopic assembly 100 and the roller assembly 200, so that the pressure applied by the telescopic assembly 100 to the roller assembly 200 can be linearly increased through the buffer assembly 400, the pressure is more controllable, and it can be ensured that the roller assembly 200 is completely abutted against the top of the graphite boat 2000. Even when the graphite boat 2000 vibrates up and down along the first direction, the roller 220 of the roller assembly 200 can always be attached to the top of the graphite boat 2000 under the elastic force of the buffer assembly 400.

[0054] The distance between the connection position of the buffer assembly 400 and the connection plate 120 and the connection position of the telescopic portion 110 and the connection plate 120 is L, the force of the buffer assembly 400 along the first direction is F, and the boat-racing device 1000 satisfies:

[0055]

[0056] That is, the connection position between the telescopic part 110 and the connecting plate 120 is taken as the origin, the connection position between the buffer assembly 400 and the connecting plate 120 is taken as the force application point, N buffer application points, that is, there are N force application points, the distance from the force application point to the origin forms a lever arm L, the force along the first direction at the force application point is F, F*L is the moment, when the buffering force of each buffer assembly 400 is equal, the boat-beating device 1000 satisfies that the resultant moment on the connecting plate 120 is 0 (considering the influence of errors such as production errors and installation errors, the specific values ​​of F and L should be averaged, and the resultant moment should be regarded as equal to 0 when it is extremely small), which is specifically achieved by the following method:

[0057] 1. When N=1, the connection position between the buffer assembly 400 and the connection plate 120 and the connection position between the telescopic assembly 100 and the connection plate 120 are located on the same straight line along the first direction;

[0058] 2. When N=2, the connection positions of the two buffer components 400 and the connection plate 120 are arranged symmetrically with respect to the connection position of the telescopic component 100 and the connection plate 120;

[0059] 3. When N≥3, the connection positions of all buffer components 400 and the connection plate 120 are symmetrically arranged about the center of the connection position of the telescopic component 100 and the connection plate 120, or are evenly distributed around the circumference of the connection position of the telescopic component 100 and the connection plate 120.

[0060] For example, when the number of buffer components 400 is three, the three buffer components 400 can be distributed in a straight line, the connection position between the middle buffer component 400 and the connecting plate 120, and the connection position between the telescopic component 100 and the connecting plate 120 are located on the same straight line along the first direction, and the connection positions between the buffer components 400 and the connecting plate 120 at both ends are symmetrically arranged about the center of the connection position between the telescopic component 100 and the connecting plate 120; or, the three buffer components 400 are evenly distributed around the connection position between the telescopic component 100 and the connecting plate 120 in a circle, the angle corresponding to the fan-shaped area between the two buffer components 400 is 120°, and the connecting lines of the three buffer components 400 form an equilateral triangle.

[0061] In addition, when the buffering force of each buffer component 400 is different, it is necessary to perform adaptive adjustment according to the buffering force size and position of each buffer component 400 to meet the requirement that the resultant moment is 0.

[0062] It is worth understanding that the telescopic component 100 is arranged in parallel with the vibration component 300, and the telescopic component 100 is connected to the roller component 200 through the buffer component 400. On the connecting plate 120 of the telescopic component 100, the connecting position between the telescopic part 110 and the connecting plate 120 is taken as the force center. When the resultant moment formed from the connecting position between the buffer component 400 and the connecting plate 120 to the force center is 0, no bending moment is generated between the telescopic component 100 and the buffer component 400, and the telescopic component 100 and the roller component 200 are distributed in a straight line along the first direction, so that no bending moment is generated between the telescopic component 100 and the roller component 200, so that the telescopic force action line of the telescopic component 100 and the reaction force line of the roller 220 are on the same straight line, and the telescopic force of the telescopic component 100 can be directly transmitted to the roller 220 of the roller assembly 200, thereby improving the service life of the boat-beating device 1000, reducing the probability of equipment damage, and reducing maintenance costs.

[0063] Reference Figure 2 As shown, in some specific embodiments of the present invention, the vibration assembly 300 includes a vibration source 310 connected to the fixed plate 210, and the vibration source 310 is spaced apart from the telescopic assembly 100 along a third direction to vibrate the fixed plate 210 along a first direction, and the third direction is perpendicular to the first direction and the second direction.

[0064] It is worth understanding that the vibration source 310 vibrates the fixed plate 210, thereby driving the roller 220 connected to the fixed plate 210 to vibrate to achieve the boat-beating effect, and the vibration source 310 is arranged parallel to and at intervals with the telescopic component 100 along the third direction to install the boat-beating device 1000 in a limited installation space.

[0065] The vibration assembly 300 further includes a vibration plate 320, the vibration plate 320 includes a connection portion and an extension portion connected to the connection portion, the connection portion is connected to the fixed plate 210, the extension portion extends from the fixed plate 210 along the third direction, and the telescopic portion 110 is provided with a vibration source 310. The vibration source 310 is suspended and connected to the fixed plate 210 through the vibration plate 320, so that the vibration source 310 is parallel to the telescopic assembly 100 along the third direction and is arranged at intervals.

[0066] In this embodiment, the connection portion is connected to the middle of the fixing plate 210. It is worth noting that the connection portion is connected to the middle of the fixing plate 210, so that the two ends of the fixing plate 210 can be symmetrical about the center of the connection position of the connection portion and the fixing plate 210, and the vibration source 310 passes through the middle of the fixing plate 210 to evenly distribute the vibration force to the two ends of the fixing plate 210, and then transmits it to the roller 220 of the roller assembly 200, so that the force on the roller 220 is more balanced.

[0067] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some specific embodiments of the present invention, the buffer assembly 400 includes a guide rod 410 and an elastic member 420 sleeved on the outer peripheral surface of the guide rod 410. Along the first direction, one end of the guide rod 410 is slidably passed through the connecting plate 120, and the other end is connected to the fixing plate 210. The elastic member 420 is located between the connecting plate 120 and the fixing plate 210, and the two ends of the elastic member 420 are respectively abutted against the connecting plate 120 and the fixing plate 210.

[0068] Specifically, when the telescopic assembly 100 drives the roller 220 of the roller assembly 200 to abut against the top of the graphite boat 2000, the guide rod 410 of the buffer assembly 400 passes through the connecting plate 120 in a direction away from the fixed plate 210, and the distance between the connecting plate 120 and the fixed plate 210 is reduced, so that the elastic member 420 is compressed along the first direction to achieve a buffering effect. At the same time, the elastic member 420 applies a reaction force to the connection position between the elastic member 420 and the connecting plate 120. This reaction force is the reaction force F applied by the buffer assembly 400 to the connecting plate 120.

[0069] In this embodiment, the structure and material of each elastic member 420 of each buffer assembly 400 are the same, so that under the same force condition, the reaction force of each elastic member 420 is the same.

[0070] In addition, the buffer assembly 400 further includes a guide sleeve 430 , through which the guide rod 410 is inserted into the connecting plate 120 , and the guide sleeve 430 is fixed on the connecting plate 120 , so that the guide rod 410 can slide more smoothly and reduce the influence of friction.

[0071] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of the utility model, the fixed plate 210 includes a base plate 211 and a rotating shaft 212 connected to the base plate 211, the base plate 211 is connected to the buffer assembly 400, and a side of the base plate 211 away from the connecting plate 120 is provided with two protrusions 2111 spaced apart along the second direction, the rotating shaft 212 is provided between the two protrusions 2111, and the two ends of the rotating shaft 212 are respectively connected to the two protrusions 2111, and the outer circumferential surface of the rotating shaft 212 is provided with a roller 220.

[0072] It is worth understanding that the rotating shaft 212 is fixed by the protrusion 2111 of the fixed plate 210, and the base plate 211 of the fixed plate 210 is connected to the buffer assembly 400, so that the force applied by the buffer assembly 400 is concentrated on the fixed plate 210, and the force applied to the rotating shaft 212 by the roller 220 is concentrated on the protrusion 2111, and the force is applied at different positions of the base plate 211 to avoid damage caused by long-term stress concentration and improve the service life.

[0073] In this embodiment, the protrusion 2111 is integrally formed with the base plate 211 or is detachably connected. Alternatively, two protrusions 2111 are respectively provided at both ends of the base plate 211 along the second direction, and the protrusions 2111 are integrally formed with the base plate 211 or are detachably connected. The two axial ends of the roller 220 are disposed on the rotating shaft 212 through the rotating shaft 212 bearing sleeves.
