Description

Technical Field

[0001] The utility model relates to the technical field of PVC tablecloth production, in particular to a flattening device for PVC tablecloth production. Background Art

[0002] Tablecloth is an item that covers the table or desktop to prevent dirt or increase its beauty. It is also called: tablecloth. Because it is customary to cover the table, it is also called tablecloth. Due to domestic and foreign usage habits and table specifications, the shapes and names are different. There are square table covers, round table covers, tea table covers, dining table covers, etc. They are mainly used for display, banquets, and dining. They are generally suitable for elegant places such as restaurants, hotels, and teahouses.

[0003] For example, the patent document with the announcement number CN 210916663 U discloses a steam ironing device for billiard table cloth production, comprising: a mounting base, two groups of support columns, a positioning plate, a conveying part mounted on the positioning plate, an ironing part and two groups of limiting mechanisms, wherein the two groups of support columns are fixedly arranged on both sides of the upper surface of the mounting base, and the positioning plate is fixedly arranged on the top of the two groups of support columns. The utility model is provided with two groups of limiting mechanisms, which can adjust the telescopic length of the sliding plate, thereby increasing the cross-over area between the sliding plate and the conveyor belt, and thus can synchronously limit the billiard table cloths of different sizes, thereby ensuring the stability of the overall operation, and at the same time, by providing a driving part, the active roller at the head end of the sliding plate can be synchronously driven to rotate, and the rotation direction of the active roller is consistent with the working direction of the conveyor belt, thereby stably conveying the billiard table cloth, and avoiding the friction between the active roller and the billiard table cloth being too large to affect the movement of the billiard table cloth.

[0004] However, due to the limitation of its own structure, this structure can only perform the flattening and ironing operation for the production of PVC tablecloths. However, the ironed PVC tablecloths cannot be properly cooled, which affects the flattening and shaping effect and the subsequent normal production. At the same time, the equipment cannot perform the adaptive flattening operation for the production of PVC tablecloths and cannot meet the daily use needs. Therefore, it is urgent to design a flattening device for the production of PVC tablecloths to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a flattening device for PVC tablecloth production, so as to solve the problem that the existing structure mentioned in the above background technology can only perform the flattening and ironing operation for PVC tablecloth production due to its own structural limitations, but the ironed PVC tablecloth cannot be properly cooled, which affects its flattening and shaping effect and subsequent normal production. At the same time, the equipment cannot perform the adaptability flattening operation for PVC tablecloth production and cannot meet the daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flattening device for producing PVC tablecloths, comprising a flattening frame, the top end of the flattening frame is fixedly connected to a top shrinking frame, the bottom end of the flattening frame is fixedly connected to a bottom shrinking frame, a heating unit is arranged at one end of the bottom of the flattening frame, and a refrigeration unit is arranged at the other side of the bottom of the flattening frame;

[0007] Guide frames, both ends of the flattening sleeve are fixedly connected with guide frames, one end of the two groups of guide frames away from each other is fixedly connected with a limiting frame, and a central rolling ball is arranged at the inner center of the limiting frame.

[0008] Preferably, adjustment slide grooves are provided on both sides of the interior of the limiting frame, and side rolling balls are provided inside the adjustment slide grooves.

[0009] Preferably, temperature control frames are provided at the upper and lower ends of the guide frame, and a temperature control tube is provided inside the temperature control frame.

[0010] Preferably, a connecting valve seat is provided at one end of the heating unit and the refrigeration unit, and a circulation pipe is provided on the top of the connecting valve seat.

[0011] Preferably, shrinkage grooves are provided inside the top shrinkage frame and the bottom shrinkage frame, and shrinkage airbags are provided on the surfaces of the shrinkage grooves.

[0012] Preferably, one end of the shrink airbag is fixedly connected to an arc-shaped cover, and a flattening roller is arranged inside the arc-shaped cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The flattening device for PVC tablecloth production can make the equipment perform rapid heat softening and cold setting operations on the PVC tablecloth during the production and flattening of the PVC tablecloth by means of the flattening frame, heating unit, refrigeration unit, guide frame, temperature control frame, temperature control pipe, connecting valve seat, circulation pipe and flattening roller. In actual use, the staff first inserts the PVC tablecloth to be flattened from the inside of the guide frame on one side, and then passes through the flattening frame into the inside of the guide frame on the other side, and the upper and lower sets of flattening rollers inside the flattening frame are used to perform stable production of the PVC tablecloth. During the production flattening operation, the heating unit and the refrigeration unit on both sides of the bottom of the flattening rack can be started, and they cooperate with their respective connecting valve seats and circulating pipes to connect with the temperature control racks and temperature control pipes at the upper and lower ends of the guide rack. The cold and hot water are circulated inside the temperature control racks and temperature control pipes of the guide racks on both sides, so that the PVC tablecloth can be softened by heat before entering the flattening rack to improve the flattening effect. After the flattening is completed, it enters the guide rack for cold setting operation, which greatly improves the final PVC tablecloth production flattening and retention effect, reflecting the practicality of the equipment design.

[0015] The flattening device for PVC tablecloth production further improves the overall use effect of the equipment by means of the flattening frame, top shrinking frame, bottom shrinking frame, limiting frame, center rolling ball, adjusting chute, side rolling ball, shrinking groove, shrinking airbag, arc cover and flattening roller. In daily use, before the PVC tablecloth enters the two sets of guide frames, it needs to be inserted inside the limiting frame. At this time, the center rolling ball in the center of the limiting frame limits the position of the PVC tablecloth, and the side rolling balls in the adjusting chute on both sides can be adjusted to adjust the position of the PVC tablecloth on both sides. At the same time, the top shrinking frame and the bottom shrinking frame at the upper and lower ends of the flattening frame are respectively adjusted to be more adaptable and retractable through the shrinking airbags in the shrinking groove, so that the flattening roller inside the arc cover always performs a more adaptable and tightening flattening operation at the upper and lower positions of the PVC tablecloth, which reflects the comprehensiveness of the equipment design.
