Description

Technical Field

[0001] The utility model relates to the technical field of blank grinding machines, in particular to a reciprocating blank grinding machine. Background Art

[0002] During the ceramic tile production process, tiny particles of dust and impurities inevitably accumulate on the surface of the ceramic tile after it undergoes high-pressure pressing. If these particles aren't removed promptly, they can cause a series of problems in subsequent processes. Especially during the glazing process, if the ceramic tile surface isn't cleaned, dust and impurities can mix directly into the glaze, causing surface defects like impurities and spots. This not only diminishes the aesthetics of the ceramic tile but also seriously impacts its overall quality and market competitiveness.

[0003] To address this issue, traditional press sweepers typically use disc grinders for surface cleaning. However, disc grinders struggle to ensure uniformity during the grinding process, often resulting in over-grinding of some areas of the product surface and under-grinding of others, leading to poor surface flatness and a poor aesthetic appearance. Furthermore, the grinding components of disc grinders are relatively hard, making them prone to scratching the surface during the grinding process, further reducing product quality. Furthermore, disc grinders generate considerable noise at high speeds, which not only impacts the work environment but can also damage the operator's hearing. Utility Model Content

[0004] In view of the above defects, the utility model proposes a reciprocating blank grinding machine, which solves the problems of uneven blank grinding, easy scratching of product surface and high noise in traditional disc blank grinding machines.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The reciprocating drive mechanism includes a driving member, a crank, a swing arm and a fixed block;

[0008] The driving member is installed on the frame, the output end of the driving member is fixedly connected to the inner ring of the crank, the head end of the swing arm is hinged to the outer ring of the crank, the tail end of the swing arm is hinged to the fixed block, and the fixed block is installed on the top of the skateboard.

[0009] The position limiting guide mechanism includes a slide rail and a pulley. The slide rail is installed on the top of the frame. The slide rail is slidably connected to the pulley. The pulley is installed on the bottom of the slide.

[0010] The height adjustment mechanism includes a screw, a first nut and a second nut;

[0012] The fixing block includes a horizontal portion, a vertical portion and a mounting portion. The vertical portion is arranged around the horizontal portion, the top of the vertical portion is vertically connected to the horizontal portion, and the bottom of the vertical portion is fixedly connected to the mounting portion.

[0016] The technical solutions provided by the embodiments of the present application may have the following beneficial effects:

[0017] 1. A sponge is installed at the bottom of the slide, so that the reciprocating drive mechanism can drive the slide and the sponge to move together. When the sponge is in reciprocating motion, the lower surface of the sponge will be in close contact with the upper surface of the blank. Due to the good softness, wear resistance and resilience of the sponge, it can effectively absorb and disperse the impact force generated during the grinding process, so that the sponge can form a uniform contact with the upper surface of the blank, thereby achieving fine grinding of the blank surface, removing burrs, uneven parts and excess impurities on the blank surface, making the blank surface smoother and flatter, and solving the problem of uneven grinding and easy scratching of the product surface in traditional disc-type blank grinding machines.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means more than two.

[0027] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installation," "splicing," and "connection" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] The following combination Figures 1 to 4 , describing a reciprocating blank grinding machine according to an embodiment of the present utility model.

[0029] A reciprocating blank grinding machine includes a frame 1, a reciprocating drive mechanism 2, a limit guide mechanism 3, a slide 4, a height adjustment mechanism 5 and a sponge 6. The frame 1 is equipped with the limit guide mechanism 3, the limit guide mechanism 3 is fixedly connected to the slide 4, the reciprocating drive mechanism 2 is installed on the frame 1, the driving end of the reciprocating drive mechanism 2 is hinged to the slide 4, the reciprocating drive mechanism 2 is used to drive the slide 4 to slide, the limit guide mechanism 3 is used to limit the sliding direction and sliding range of the slide 4, and the sponge 6 is provided at the bottom of the slide 4.

[0030] In this scheme, a reciprocating blank grinding machine is provided. When the reciprocating drive mechanism 2 is started, the slide plate 4 can be driven to move on the frame 1. At this time, the limiting guide mechanism 3 on the frame 1 can limit the sliding direction and sliding range of the slide plate 4, so that the slide plate 4 can reciprocate on the frame 1.

[0031] A sponge 6 is mounted on the bottom of the slide 4, allowing the reciprocating drive mechanism 2 to drive the slide 4 and the sponge 6 to move together. During the reciprocating motion, the lower surface of the sponge 6 will closely adhere to the upper surface of the blank. Due to the good softness, wear resistance and resilience of the sponge 6, it effectively absorbs and disperses the impact force generated during the grinding process, allowing the sponge 6 to form a uniform contact with the upper surface of the blank, thereby achieving fine grinding of the blank surface, removing burrs, uneven parts and excess impurities on the blank surface, making the blank surface smoother and flatter, and solving the problem of uneven grinding and easy scratching of the product surface in traditional disc-type blank grinding machines.

[0032] In order to better grind the blank, the moving direction of the slide plate 4 in this solution is perpendicular to the conveying direction of the blank, so as to ensure that the sponge 6 can grind the blank in all directions.

[0033] Moreover, the present solution adopts the sponge body 6 for grinding blanks, which can effectively reduce the noise and vibration generated during the grinding process, improve the comfort of the working environment, extend the service life of the reciprocating drive mechanism 2 and the slide 4, and solve the problem of high noise in traditional disc-type blank grinding machines.

[0034] The reciprocating drive mechanism 2 includes a driving member 21, a crank 22, a swing arm 23 and a fixing block 24;

[0035] The driving member 21 is installed on the frame 1, the output end of the driving member 21 is fixedly connected to the inner ring of the crank 22, the head end of the swing arm 23 is hinged to the outer ring of the crank 22, and the tail end of the swing arm 23 is hinged to the fixed block 24, and the fixed block 24 is installed on the top of the slide 4.

[0036] It is worth noting that the drive is a reduction motor. When the drive element 21 is activated, the drive element 21 drives the crank 22 in circular motion. Because the outer ring of the drive is hinged to the head end of the swing arm 23, and the tail end of the swing arm 23 is hinged to the fixed block 24, the rotation of the crank 22 can drive the swing arm 23 and the fixed block 24 to move back and forth. The fixed block 24 is mounted on the top of the slider, allowing the reciprocating drive mechanism 2 of this solution to drive the slider to slide back and forth on the frame 1, ensuring that the sponge 6 moves back and forth to grind the brick body.

[0037] In addition, by adjusting the geometric parameters of the crank 22, the motion range and frequency of the swing arm 23 can be conveniently changed to meet the grinding requirements of different production lines.

[0038] The position limiting guide mechanism 3 includes a slide rail 31 and a pulley 32 . The slide rail 31 is installed on the top of the frame 1 . The slide rail 31 is slidably connected to the pulley 32 . The pulley 32 is installed on the bottom of the slide plate 4 .

[0039] The pulley 32 is installed at the bottom of the skateboard 4, and the pulley 32 is slidably connected to the slide rail 31, so that the pulley 32 can drive the skateboard 4 to slide on the slide rail 31. At this time, the pulley 32 limits the sliding path of the skateboard 4, so that the skateboard 4 can move along a predetermined trajectory, thereby ensuring precise position control.

[0040] Moreover, the sliding connection between the slide rail 31 and the pulley 32 can reduce the friction and resistance during the movement, making the slide plate 4 more stable and smooth when moving, which helps to reduce the wear and failure rate of the grinding machine of this solution and extend its service life.

[0041] The height adjustment mechanism 5 includes a screw 51, a first nut 52 and a second nut 53;

[0042] The top of the screw rod 51 is vertically installed on the bottom of the slide 4. The bottom of the screw rod 51 is threadedly connected with the first nut 52, the fixing block 24 and the second nut 53 in sequence. The first nut 52 and the second nut 53 clamp the fixing block 24 with each other.

[0043] The screw rod 51 and the first nut 52, as well as the screw rod 51 and the second nut 53, are connected by a threaded connection, allowing operators to quickly and easily achieve very precise height adjustments. Simply by rotating the corresponding nut, the height of the fixed block 24 can be fine-tuned or significantly adjusted, making height adjustment of the fixed block 24 simple and efficient.

[0044] Furthermore, the first nut 52 and the second nut 53 mutually clamp the fixing block 24, which effectively ensures the stability of the fixing block 24 after the height is adjusted. Even when subjected to external forces or vibrations, the fixing block 24 can maintain its set position without shaking or shifting.

[0045] If a component is damaged or needs to be replaced, the staff can easily disassemble and replace it by simply unscrewing the corresponding nut, which greatly reduces the difficulty and cost of maintenance and replacement of the grinding machine of this solution.

[0046] The fixing block 24 includes a horizontal portion 241, a vertical portion 242, and a mounting portion 243. The vertical portion 242 is arranged around the horizontal portion 241. The top of the vertical portion 242 is vertically connected to the horizontal portion 241, and the bottom of the vertical portion 242 is fixedly connected to the mounting portion 243. The cross-section of the fixing block 24 is a quadrilateral structure.

[0047] The screw rod 51 is threadedly connected to the horizontal portion 241 , the first nut 52 and the second nut 53 clamp the horizontal portion 241 with each other, and the sponge 6 is fixedly mounted on the bottom of the mounting portion 243 .

[0048] The top of the vertical portion 242 is vertically connected to the horizontal portion 241, and the bottom of the vertical portion 242 is connected to the mounting portion 243 above the top, thereby forming a stable quadrilateral frame. The quadrilateral structure can greatly enhance the overall structural stability of the fixing block 24, enabling it to withstand greater pressure and load while maintaining its shape.

[0049] Moreover, a gap is left between the horizontal portion 241 and the mounting portion 243 , which can effectively prevent the screw from passing through the mounting portion 243 and causing damage to the sponge 6 .

[0050] An adhesive layer 244 is provided at the bottom of the mounting portion 243 , and the sponge 6 is adhered to the bottom of the adhesive layer 244 .

[0051] It is worth noting that the adhesive layer 244 is a self-adhesive cloth. Both sides of the self-adhesive cloth are sticky, so that the upper surface of the self-adhesive cloth is adhered to the fixing block 24, and the lower surface of the self-adhesive cloth is adhered to the sponge 6, thereby ensuring that the sponge 6 can be fixedly installed on the fixing block 24, reducing the complexity and time required for the installation of the sponge 6.

[0052] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
