Description

Technical Field

[0001] The utility model belongs to the field of glass production, and in particular relates to a wheel stop device for a calender. Background Art

[0002] The calender is the most core equipment in the production process of photovoltaic glass. The molten high-temperature glass liquid is pressed and cooled by the calender to form a glass strip of a certain thickness. The thickness is mainly determined by the pressure applied to the calender by the pressure bar system. The convex heads of the two pressure bars are pressed at nearly vertical angles into the grooves on the roller sleeves at both ends of the calender. However, in the production process, due to various reasons such as roller damage near the edge of the calender roller that cannot be removed, the position of the calender needs to be readjusted so that the force applied by the pressure bar is not vertical. The small angle generated will inevitably generate left and right thrusts, causing the position of the calender to change, resulting in pressure changes. In severe cases, the thickness of the glass plate may exceed the tolerance. Other reasons, such as machine vibration, may also cause changes in the position of the calender.

[0003] Therefore, the stability of the calender position is a project that must be controlled. The previous common practice is to make a piece of wood into a wedge shape or stuff it with a wooden board or cotton gloves, but one is that it is not firmly fixed and is easy to fall off, or it is made into a limit device but is not easy to adjust. Therefore, it is very necessary to find a method that is accurate in limiting and easy to adjust. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a calender wheel stopping device, which overcomes the problems of loose fixation and inconvenient adjustment in traditional methods of controlling the stability of the calender, and can effectively prevent the position of the machine from changing during the glass pressing process of the calender. It is more stable and effective than the original method, and is more convenient to install and disassemble.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A calender wheel stopping device is composed of a left and a right wheel stopping assembly, which are arranged in mirror symmetry. The left wheel stopping assembly includes a left wheel stopping block and a left wheel stopping clamp, and the right wheel stopping assembly includes a right wheel stopping block and a right wheel stopping clamp. The cross-sections of the left and right wheel stopping blocks are right-angled trapezoids, and the wheel stopping block inclined surfaces on the left and right wheel stopping blocks are arranged opposite to each other. The left and right wheel stopping clamps are U-shaped plates with openings arranged opposite to each other. The left and right wheel stopping clamps are provided with wheel stopping clamp inclined surfaces at one end on the same side thereof, and left and right connecting plates are vertically provided at the other ends. The left and right wheel stopping blocks are respectively arranged on the upper end surfaces of the left and right wheel stopping clamps, and the angles of the wheel stopping block inclined surfaces and the wheel stopping clamp inclined surfaces are consistent and located on the same inclined surface. The left and right wheel stopping assemblies are connected by left and right connecting plates.

[0007] Furthermore, the wheel stop block is provided with an adjustment long hole, and the wheel stop clamp is provided with a positioning wire hole corresponding to the adjustment long hole, and the wheel stop block is fixedly connected to the wheel stop clamp by inserting a locking positioning wire.

[0008] Furthermore, the connecting plate is welded and fixed to the wheel stopper, a connecting bolt is welded on the right connecting plate, a connecting through hole is provided at a corresponding position of the left connecting plate, and the left and right connecting plates are connected by tightening the connecting nut.

[0009] Furthermore, the wheel stopper is made of metal material, and the wheel stop block is made of polytetrafluoroethylene material.

[0010] The beneficial effects of the utility model are as follows: the utility model is designed with a left and right stopper combination, which is inserted between the travel wheel and the travel guide rail of the calender in the form of a "wedge", and the travel wheel is clamped and fixed, and connected into a whole through connecting bolts and nuts.

[0017] Example 1

[0018] The calender wheel stop device of the utility model is as follows Figure 1-4 As shown, the wheel stop block 1 and the wheel stop clamp 2 form a left and right wheel stop assembly, and the left and right wheel stop assemblies are arranged in mirror symmetry. The left wheel stop assembly includes a left wheel stop block 101 and a left wheel stop clamp 201, and the right wheel stop assembly includes a right wheel stop block 102 and a right wheel stop clamp 202. The cross-sections of the left and right wheel stop blocks are both right-angled trapezoids, and the material thereof is polytetrafluoroethylene material. Two adjustment long holes 103 are respectively provided on the left and right wheel stop blocks, and the wheel stop block inclined surfaces 104 on the left and right wheel stop blocks are arranged oppositely; the left and right wheel stop clamps are both U-shaped metal plates, and the opening directions of the U-shaped grooves 205 of the left and right wheel stop clamps are arranged oppositely, and the left and right wheel stop clamps are opposite at one end on the same side. A wheel stop clamp inclined surface 204 is provided, and two positioning wire holes 203 are provided corresponding to the adjustment long hole 103. The left and right wheel stop blocks are respectively arranged on the upper end surfaces of the left and right wheel stop clamps. The inclined surface 104 of the wheel stop block and the inclined surface 204 of the wheel stop clamp have the same inclined surface angle and are located on the same inclined surface. The wheel stop block 1 and the wheel stop clamp 2 are fixedly connected by inserting and locking the positioning wire; the other ends of the left and right wheel stop clamps are welded and fixed with vertical left and right connecting plates, and a connecting bolt 208 is welded on the right connecting plate 207. A connecting through hole 209 is provided at the corresponding position of the left connecting plate 206. The locking connecting nut 210 connects the left and right connecting plates and then connects the left and right wheel stop assemblies into one.

[0019] When in use, first install the wheel stopping device, place the left wheel stopping block 101 and the right wheel stopping block 102 on the left wheel stopping clamp 201 and the right wheel stopping clamp 202 respectively, adjust the wheel stopping block inclined surface 104 and the wheel stopping clamp inclined surface 204 so that they are located on the same inclined surface, then insert the positioning wire into the adjustment long hole 103 and lock it with the positioning wire hole 203 to form a left and right wheel stopping combination, and its end forms a "wedge" shape, and then insert the two wheel stopping combinations from the left and right sides of the running wheel 3 of the calender 4 respectively, so that the lower bottom surface of the wheel stopping clamp 2 is in close contact with the guide rail 5, and the inclined surface is in close contact with the running surface of the running wheel 3, so that the outer clamping plate of the running wheel 3 falls into the "U"-shaped groove 205, and finally tighten the connecting nut 210 to connect the left and right connecting plates and then connect the left and right wheel stopping combinations into one.

[0020] The left and right wheel stop assemblies of the present device have "wedge"-shaped ends which are inserted between the traveling wheel 3 and the guide rail 5, and are connected together and restrained from each other, so that the loosening and change of the previous positioning will not occur. The present device utilizes a combination of a wheel stop card inclined surface 204 and an elastic and wear-resistant polytetrafluoroethylene wheel stop block inclined surface 104, which is both firm and elastic, so that it can position firmly and well protect the traveling wheel 3 of the calender 4. When the device needs to be released, it is only necessary to loosen the connecting nut 210 to disassemble and take out the left and right wheel stop assemblies, so that installation and disassembly are more convenient.
