Description

Technical Field

[0001] The utility model relates to the technical field of edge straightening machines, in particular to a rear pressing plate for edge straightening machines. Background Art

[0002] The glass edge grinding machines on the market are generally glass straight edge machines, which have low working efficiency. Due to the imperfect design, the rear pressing plate of this type of glass straight edge machine generally uses two rear pressing plates to clamp the two planes of the glass. The rear pressing plate and the glass are transported by the conveyor belt while being edged by the straight edge machine. A lot of dust will be generated during edge grinding. Generally, circulating water is used to cool the grinding wheel and absorb dust. The existing patent application announcement number CN210909548U discloses a straight edge machine rear pressing plate. In order to solve the problems of glass powder circulating water not being able to be smoothly guided out of the rear pressing plate in the traditional glass edge grinding machine, and the machine vibrating during grinding, the rear pressing plate clamping the glass vibrates greatly, thereby reducing the processing accuracy of the whole machine, the processing efficiency is low, and the soft rubber plate clamping the glass is easy to fall off, thereby affecting its service life. The multi-layer mosaic of the soft rubber plate and the clamping plate achieves a multi-level shock absorption effect, so that the glass can be clamped more stably by the utility model, thereby improving the processing accuracy;

[0003] However, the soft rubber plate on the rear pressure plate of the straight edge machine is embedded with the clamping plate. When the soft rubber plate contacts the glass and the glass is subjected to force during edge grinding, the force borne is transmitted to the soft rubber plate, and the soft rubber plate will produce a certain deformation. Since the soft rubber plate and the clamping plate are embedded and assembled, the deformation of the soft rubber plate is very likely to cause the soft rubber plate to fall off the clamping plate, which affects the stability of the glass clamping and edge grinding operation and increases the defective rate of glass edge grinding.

[0004] Therefore, the utility model provides a rear pressing plate for a straight edge machine which can keep the soft rubber plate and the clamping plate stably assembled. Utility Model Content

[0005] The utility model aims to provide a rear pressing plate for a straight edge machine to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rear pressing plate for a straight edge machine, comprising a clamping plate connected to the straight edge machine and cooperating with a conveyor belt to convey glass or stone, and a supporting plate arranged on the clamping plate and cooperating with the clamping plate to receive the glass or stone, wherein an embedding groove matching the size of the supporting plate is arranged on the upper surface of the clamping plate, the supporting plate is embedded in the embedding groove, and a plurality of limit slots connected with the embedding groove and arranged above the supporting plate are arranged on the left side of the clamping plate;

[0008] The upper surface of the support plate is provided with a rectangular receiving groove, in which a soft rubber board is clamped, and a plurality of plastic plates on the left side of the soft rubber board are clamped in the limiting clamping groove to limit the soft rubber board in the rectangular receiving groove;

[0009] The soft rubber plate is provided with a plurality of glass clamping rubber blocks protruding from the surface of the soft rubber plate, and a circulating water guide groove is formed between the plurality of glass clamping rubber blocks.

[0010] Furthermore, a circulating water outlet groove connected to the circulating water guide groove is provided on the right side of the support plate. The circulating water outlet groove is used to cooperate with the circulating water guide groove to guide the glass powder circulating water for cooling the glass or stone out of the surface of the rear pressure plate, so as to avoid the problem that the glass powder circulating water stays on the surface of the rear pressure plate and affects the edge grinding process of the glass or stone.

[0011] Furthermore, the upper surface of the support plate is provided with a plurality of receiving grooves arranged in the rectangular receiving groove, and the bottom surface of the soft rubber board is provided with a plurality of limiting protrusions corresponding to the receiving grooves. The bottom surface of the soft rubber board is connected with the receiving grooves through the limiting protrusions and the position of the soft rubber board in the rectangular receiving groove is limited. When the rubber board is inserted into the rectangular receiving groove, the limiting protrusions on the bottom surface of the soft rubber board are inserted into the receiving grooves, so that the bottom surface of the soft rubber board is limited in the rectangular receiving groove in multiple directions and multiple points through the limiting protrusions and the receiving grooves after the clamping, thereby improving the stability of the connection between the soft rubber board and the support plate.

[0012] Furthermore, the back side of the plastic plate is fixed to the bottom side of the limiting protrusion and the end of the plastic plate extending out of the left side of the supporting plate is inserted into the limiting slot. The left end of the plastic plate extends out of the left side of the supporting plate. When the plastic plate is connected to the supporting plate, the end extending out of the supporting plate is inserted into the limiting slot, and the right side of the soft rubber plate is inserted into the limiting receiving slot, thereby achieving the effect of quickly and stably installing the soft rubber plate into the supporting plate.

[0013] Furthermore, front supporting side wings and rear supporting side wings are respectively provided at the front and rear ends of the bottom of the splint, and reinforcing ribs are provided at the inner sides of the front supporting side wings and the rear supporting side wings connected to the splint. The reinforcing ribs increase the strength of the front supporting side wings and the rear supporting side wings in cooperating with the splint to support the glass or stone and withstand pressure, thereby improving the splint's ability to resist deformation under pressure.

[0014] Furthermore, a transverse arc-shaped avoidance groove is provided in the middle portion of the rear supporting side wing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The straight edge machine uses a rear pressing plate, and a plastic plate corresponding to the upper limit slot of the support plate is arranged on the left side of the soft rubber plate. When the soft rubber plate is connected to the support plate, the plastic plate on the left side of the soft rubber plate is first inserted into the limit slot, and the other side of the soft rubber plate is inserted into the rectangular receiving slot as the soft rubber plate moves to the position of the rectangular receiving slot, so that the soft rubber plate and the rectangular receiving slot are completely embedded. When the glass clamping rubber block on the soft rubber plate cooperates with the glass for clamping and transmission, the left side of the soft rubber plate is limited and fixed by the plastic plate and the limit slot, and the right side of the soft rubber plate is closely fixed to the inner side of the rectangular receiving slot, so as to achieve the purpose of fixing the soft rubber plate in the rectangular receiving slot. Even if the glass or stone is subjected to the change of the grinding force angle of the edge grinding machine, the soft rubber plate will not tilt with the change of the force angle of the glass or stone, thereby improving the stability of the soft rubber plate and the clamping plate in clamping and transmitting the edge grinding of the glass or stone, and avoiding the problem of the glass or stone moving during the edge grinding process and increasing the defective rate.
