Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a cutting equipment for processing ceramic hanging pieces. Background Art

[0002] Ceramic hanging clay is a special clay material used to make ceramic hangings. This kind of clay usually has high plasticity and adhesion, and can bond ceramic materials well. When making ceramic hangings, the clay must first be cut into blocks of appropriate size, and then kneaded and fired.

[0003] The Chinese invention patent with the announcement number CN118288403B discloses a production and cutting device for ceramic hanging pieces, including a conveyor belt device, the conveyor belt device is provided with a cutting device for cutting ceramic hanging piece clay, the conveyor belt device is provided with an adjustment mechanism for adjusting the cutting length, the conveyor belt device is provided with a collection mechanism for collecting the cut material, the cutting device includes a cross bar and a cutting knife, and the adjustment mechanism includes a fixed circular plate, a push rod and an L-shaped slider. The device is provided with an adjustable push rod, so that when the ceramic hanging piece clay is cut, the size of the ceramic hanging piece clay cut can be adjusted according to the production requirements of the hanging piece. If the gap between the push rods is adjusted to be larger, the ceramic hanging piece clay cut out will be larger, and if the gap between the push rods is adjusted to be smaller, the ceramic hanging piece clay cut out will be smaller. It can meet diverse production needs and has high adaptability.

[0004] However, the above patent still has the following shortcomings in actual use: the patent drives the circular plate to rotate through the driving force of the conveyor belt, and the circular plate drives the push rod to rotate synchronously with it. The push rod gradually contacts the arc block as the circular plate rotates, and then drives the cutting knife downward through the arc height difference of the arc block. During the downward movement of the cutting knife, the transmission belt still drives the ceramic hanging clay to move forward, and the forward movement distance is exactly the arc length of the arc block. It can be seen that this moving distance is relatively long. The cutting knife cuts the moving ceramic hanging clay, which will cause the cut surface of the ceramic hanging clay to be very uneven, thereby affecting the processing quality of the ceramic hanging. Summary of the invention

[0035] The present invention can drive the push frame 2 to move forward by pushing the electric push rod 112 horizontally. The stability of the movement of the push frame 2 can be ensured by the cooperation of the guide groove 13 and the guide block 22. The push frame 2 can push the ceramic hanging clay forward. During the pushing process, the knocking mechanism 3 passes through all the lifting blocks 4 in sequence. The knocking mechanism 3 cooperates with the lifting block 4 to knock all the transmission blocks 43 in sequence. The transmission block 43 can transmit the knocking force to the force-bearing plate 5, and the force-bearing plate 5 can then move downward. After the two force-bearing plates 5 move downward, they can drive the L-axis frame, the mounting plate 55, the fixing mechanism 7 and the cutting knife 8 to move downward to complete the cutting operation. The interval of the cutting operation is determined by the distance between the two transmission blocks 43. The distance between the two adjacent transmission blocks 43 can be adjusted, so that the cutting length of the ceramic hanging clay can be adjusted. When the cutting knife 8 moves downward, the ceramic hanging clay is in a relatively static state, thereby improving the flatness of the incision surface of the ceramic hanging clay.

[0036] In order to facilitate the transportation of the cut ceramic hanging piece clay, a transmission belt connected to the head end of the cutting table 1 can be provided to carry the cut part of the ceramic hanging piece clay by the transmission belt.

[0037] When in use, first place the ceramic hanging clay in the containing groove 12, then push the electric push rod 112 horizontally to drive the push frame 2 to move forward, and the forward movement of the push frame 2 drives the knocking mechanism 3 to move synchronously, the knocking mechanism 3 includes a synchronization plate 31, two electromagnets 32 and a proximity sensor 33, the synchronization plate 31 is provided with two symmetrically arranged guide holes, the top of the synchronization plate 31 is provided with two symmetrically arranged driven magnets 34, both sides of the bottom of the synchronization plate 31 are fixed with knocking rollers 35 by clamps, the top of the push frame 2 is provided with two symmetrically arranged first windows, a second window is provided between the two first windows, two guide rods 23 that cooperate with the guide holes are provided in the mounting groove 21, the tail end of the lifting block 4 is provided with a guiding wedge surface 431 that cooperates with the knocking roller 35, the two electromagnets 32 are respectively arranged at the two first windows, the proximity sensor 33 is arranged at the second window, and the starting block 57 can also be removably provided on the force plate 5.

[0038] The push frame 2 drives the synchronous plate 31 to move forward synchronously, and the synchronous plate 31 drives the two knocking rollers 35 to move forward synchronously, and the knocking rollers 35 gradually hit the guide wedge surface 431 of the lifting block 4, and then the knocking rollers 35 are guided by the guide wedge surface 431 to move upward, and the synchronous plate 31 is driven by the knocking rollers 35 to move upward, and the two driven magnets 34 also move upward synchronously with the synchronous plate 31, and then the synchronous plate 31 gradually approaches the proximity sensor 33, and then the synchronous plate 31 hits the proximity sensor 33, at this time the knocking rollers 35 move up along the guide wedge surface 431 to the top of the lifting block 4, and then the two electromagnets 32 work to generate a magnetic field that is the same as the magnetic field of the driven magnet 34. Due to the repulsion of the same poles, the driven magnet 34 is then subjected to a downward driving force, and the driven magnet 34 transmits the driving force to the synchronous plate 31. At this time, the knocking roller 35 is separated from the lifting block 4, Therefore, the synchronous plate 31 can be driven by the driving force to move downward rapidly, and the synchronous plate 31 drives the two knocking rollers 35 to move downward synchronously. The knocking rollers 35 knock on the transmission block 43, and the transmission block 43 moves downward rapidly. The transmission block 43 drives the force plate 5 to move downward. After the two force plates 5 move downward, they can drive the cutting knife 8 to move downward, and the cutting knife 8 can cut the ceramic hanging clay. At this time, all the first springs 53 are compressed. After cutting, the electric push rod 112 is pushed horizontally to drive the knocking roller 35 to move forward, and the knocking roller 35 can immediately disengage from the transmission block 43. The elastic force of the first spring 53 drives the force plate 5 to move upward, and the cutting knife 8 also returns to its original position. After that, the knocking roller 35 gradually contacts the guide wedge surface 431 of the next lifting block 4. In this cycle, the ceramic hanging clay can be cut into multiple ceramic hanging clay blocks, and the transmission belt can transport the ceramic hanging clay blocks away.

[0039] The starting block 57 is used to limit the starting position of the knocking roller 35 .

[0040] Furthermore, a rubber buffer block 24 is provided on the inner bottom wall of the mounting groove 21 , and the rubber buffer block 24 can avoid limiting the downward position of the synchronization plate 31 , and also provide a buffer force to prevent the synchronization plate 31 from hitting the rubber buffer block 24 and causing damage.

[0041] The length of the ceramic hanging clay block is determined by the spacing between the two transmission blocks 43. The transmission block 43 can be positioned by the positioning mechanism 6. The positioning mechanism 6 includes a pull rod 61 and a second spring 62. The bottom tail end of the pull rod 61 is provided with a pull handle 63. The head end of the pull rod 61 is provided with a first positioning block 64. The head end of the first positioning block 64 is provided with a first wedge surface 641. The bottom of the transmission block 43 and the starting block 57 are both provided with an insert block 432. The side wall of one end of the insert block 432 is provided with a first plug-in groove 4321 that is plugged and matched with the first positioning block 64. The first plug-in groove 4321 is provided on the side wall of the first plug-in groove 4321. A second wedge surface 4322 cooperating with the first wedge surface 641 is provided directly below the groove 4321, and a plurality of second plug-in grooves 56 are provided on the top of the force-bearing plate 5, which are evenly spaced along its length direction and plug-inly cooperate with the plug block 432.

[0042] The insert block 432 at the bottom of the transmission block 43 is inserted into one of the second insertion grooves 56. During the insertion process, the second wedge surface 4322 of the insert block 432 contacts the first wedge surface 641 of the first positioning block 64. The first wedge surface 641 cooperates with the second wedge surface 4322 to drive the first positioning block 64 to move backward in the horizontal sliding groove 561. The first positioning block 64 drives the pull rod 61 and the handle 63 to move backward, the second spring 62 is stretched, and then the first wedge surface 641 is disengaged from the second wedge surface 4322, and the second positioning block 734 is completely retracted into the horizontal sliding groove 561, and the first insertion groove is connected. After 4321 is docked with the horizontal sliding groove 561, the elastic force of the second spring 62 drives the pull handle 63 to move forward, and the pull handle 63 drives the pull rod 61 and the first positioning block 64 to move forward. Then the first positioning block 64 is inserted into the first plug-in groove 4321, and the first positioning block 64 cooperates with the first plug-in groove 4321 to realize the positioning of the plug-in block 432, that is, the transmission block 43 completes the quick fixation. When it is necessary to release the positioning of the plug-in block 432, it can be achieved by pulling the pull handle 63, and then the transmission block 43 can change the installation position, and the installation method of the starting block 57 is the same as the installation method of the transmission block 43.

[0043] If the transmission block 43 is positioned but the lifting block 4 is not positioned, the lifting block 4 is prone to displacement and has poor stability. Therefore, an L-shaped connecting plate 44 is provided at one end of the bottom of the lifting block 4, and a hand-tightening bolt 441 is screwed on the L-shaped connecting plate 44.

A fifth wedge surface 722 which cooperates with the third wedge surface 7341 is provided on the top of the connecting rod 72. The U-shaped sliding frame 731 and the connecting block 732 are respectively arranged on the left and right sides of the plugging hole 551. The two third springs 733 are symmetrically arranged on the front and rear sides of the plugging hole 551, and the two ends of the third spring 733 are respectively connected to the synchronization block 735 and the connecting block 732.
