Description

Technical Field

[0001] The utility model specifically relates to a mold for producing PVC tablecloths. Background Art

[0002] Tablecloths are a kind of daily necessities. For environmental protection, practical tablecloths are usually used in families, generally made of plastic, with relatively single colors, and most practical tablecloths are made of PVC texture. PVC tablecloths are popular in our country because of their characteristics of low price and good quality, and are welcomed by many families.

[0003] Therefore, in order to make PVC tablecloths more beautiful, printing equipment is needed to emboss corresponding patterns on the surface of PVC tablecloths, so that the produced clothing is more popular with consumers. The common embossing equipment is to install a roller-shaped embossing mold in the frame. However, for different patterns, it is necessary to frequently disassemble and assemble the roller-shaped embossing mold, which easily causes the roller-shaped embossing mold to deform and damage, so it is not conducive to the production of PVC tablecloths. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a mold for producing PVC tablecloths.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A mold for producing PVC tablecloths includes a rolling roller, several mold sleeve shells embedded on the surface of the rolling roller for producing PVC tablecloths, and a clamp for clamping the mold sleeve shells in cooperation with the rolling roller. The rolling roller includes a rolling roller body, several T-shaped grooves equidistantly opened around the central axis of the rolling roller body for embedding the mold sleeve shells, annular protrusions integrally formed at both ends of the rolling roller body for clamping the clamp, assembly grooves equidistantly opened on the annular protrusions around the central axis of the rolling roller body and communicating with the T-shaped grooves, and fixed shaft heads integrally formed on the central axes at both ends of the rolling roller body.

[0007] Preferably, there are three T-shaped grooves.

[0008] Preferably, the protruding height of the annular protrusion is lower than the radius of the rolling roller body.

[0009] Preferably, the mold sleeve shell includes a sleeve body in an arc shape that can be closely attached to the rolling roller body, a T-shaped embedding strip integrally formed at the center position below the inner part of the sleeve body, a clamping head extending from both ends of the T-shaped embedding strip and capable of being embedded in the assembly groove, and a semi-circular convex block integrally formed on the clamping head.

[0010] Preferably, the clamp includes a first clamp body, a second clamp body hinged to the first clamp body, and a nut for fixedly assembling in cooperation with the first clamp body and the second clamp body.

[0011] Further, a perforation is provided at the abutting end of the first clamp body and the second clamp body, and a stud that can pass through the perforation is welded and installed at the abutting end of the second clamp body and the first clamp body.

[0012] The beneficial effects of the present utility model are as follows: Through the design of the mold casing, the mold can be quickly replaced and adjusted to adapt to the production of PVC tablecloths of different specifications. The cooperation of the T-shaped grooves and the assembly grooves ensures the precise positioning of the mold casing, improves the production accuracy, and the design of the annular protrusion and the fixed shaft head enhances the stability of the mold, reducing vibration and error during the production process.

[0018] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not used as a limitation to the present utility model.

[0019] Embodiment

[0020] A mold for producing PVC tablecloths, as Figures 1-5 shown, includes a rolling roller 1, a plurality of mold casings 2 embedded on the surface of the rolling roller 1 for the production of PVC tablecloths, and a clamp member 3 for clamping the mold casings 2 in cooperation with the rolling roller 1.

[0021] The rolling roller 1 includes a rolling roller body 11, a plurality of T-shaped grooves 12 provided at equal intervals around the central axis of the rolling roller body 11 for embedding the mold casings 2, an annular protrusion 13 integrally formed at both ends of the rolling roller body 11 for clamping the clamp member 3, assembly grooves 14 provided at equal intervals around the central axis of the rolling roller body 11 on the annular protrusion 13 and communicating with the T-shaped grooves 12, and a fixed shaft head 15 integrally formed on the central axes of both ends of the rolling roller body 11.

[0022] In this embodiment, three T-shaped grooves 12 are provided.

[0023] The height of the annular protrusion 13 is lower than the radius of the rolling roller body 11. Specifically, after the clamp 3 is conveniently clamped on the annular protrusion 13 to fix the mold casing 2, the clamp 3 does not exceed the surface of the rolling roller body 11, avoiding scratching the PVC tablecloth by the clamp 3.

[0024] The mold casing 2 includes a casing body 21 arranged in an arc shape and capable of closely fitting with the rolling roller body 11, a T-shaped fitting strip 22 integrally formed at the center position below the interior of the casing body 21, a clamping head 23 extending from both ends of the T-shaped fitting strip 22 and capable of being fitted into the fitting groove 14, and a semi-circular convex block 24 integrally formed on the clamping head 23. Specifically, the casing body 21 is fixed to the rolling roller body 11 after the T-shaped fitting strip 22 passes through the T-shaped groove 12. At the same time, the clamping head 23 extends into the fitting groove 14 and is filled with the semi-circular convex block 24, which cooperates with the annular protrusion 13 to enable the clamp 3 to simultaneously clamp the annular protrusion 13 and the semi-circular convex block 24, thereby fastening the mold casing 2.

[0025] The clamp 3 includes a first clamp body 31, a second clamp body 32 hingedly installed with the first clamp body 31, and a nut 33 for fixedly assembling in cooperation with the first clamp body 31 and the second clamp body 32. A perforation 311 is provided at the abutting end of the first clamp body 31 and the second clamp body 32, and a stud 321 that can pass through the perforation 311 is welded to the abutting end of the second clamp body 32 and the first clamp body 31. Specifically, after the stud 321 passes through the perforation 311 and is screwed into the nut 33, the first clamp body 31 and the second clamp body 32 can be fixed, which is beneficial to clamping the mold casing 2 in cooperation with the rolling roller 1.

[0026] The above embodiments of the present invention do not limit the protection scope of the present invention. The implementation manners of the present invention are not limited to this. All these, based on the above content of the present invention, according to the common technical knowledge and conventional means in the art, without departing from the above basic technical idea of the present invention, various other forms of modifications, substitutions or changes made to the above structure of the present invention shall fall within the protection scope of the present invention.
