Description

TECHNICAL FIELD

[0001] The application relates to the technical field of PET production equipment, in particular to a turnover clamp for efficient transportation in PET production. BACKGROUND

[0002] PET is polyethylene terephthalate, which is the most important variety of thermoplastic polyester, commonly known as polyester resin. It is synthesized by dimethyl terephthalate and glycol exchange or by esterification of terephthalic acid and glycol to synthesize bisphenol A, and then subjected to polycondensation reaction.

[0003] The existing materials in PET production, such as PET chips, semi-finished block or columnar materials, etc., have certain differences in shape and size. In the process of transporting the materials, traditional equipment is usually used for transportation, such as forklifts.

[0004] The existing technical solutions in the above have the following defects: due to the limitations of traditional transportation equipment, a lot of time is needed for adjustment and positioning during the loading, unloading and transfer of materials, which undoubtedly reduces the overall efficiency of PET production. CONTENT OF THE UTILITY MODEL

[0005] The application provides a turnover clamp for efficient transportation in PET production in order to improve the overall efficiency of PET production.

[0006] The above technical purpose of the application is achieved through the following technical solutions:

[0007] A turnover clamp for efficient transportation in PET production, comprising a connecting structure, a turnover structure and a clamping structure, one side of the connecting structure is connected with a transportation device, the other side of the connecting structure is connected with the turnover structure, and the side of the turnover structure away from the connecting structure is fixedly connected with the clamping structure; the clamping structure comprises a connecting frame, clamping plates are arranged on both sides of the connecting frame, and the two clamping plates jointly clamp the material; a driving member is arranged between the connecting structure and the turnover structure, the driving member is fixedly connected with the connecting structure, the output end of the driving member is connected with the turnover structure, and the driving member is used for driving the turnover structure to rotate.

[0008] By adopting the above scheme, the material is placed between the two clamping plates, and the two clamping plates can clamp the material. Because the driving member is arranged, the driving member can drive the clamping structure to rotate, and the clamping structure drives the material to rotate. Therefore, the position of the material can be adjusted in time during the transportation of the material by the transportation device, and the purpose of improving the overall efficiency of PET production is achieved.

[0009] Further, the side, away from the overturning structure, of the connecting frame is provided with a first pushing member and a second pushing member, the first pushing member and the second pushing member are arranged in parallel, the first pushing member and the second pushing member are connected at positions close to the two ends of the connecting frame respectively, the extension directions of the output ends of the first pushing member and the second pushing member are opposite, and the output ends of the first pushing member and the second pushing member are fixedly connected with the two clamping plates respectively, and the first pushing member and the second pushing member jointly drive the two clamping plates to move close to or away from each other.

[0010] By adopting the above scheme, the first pushing member and the second pushing member can control the distance between the two clamping plates, and thus different specifications of materials can be clamped.

[0011] Further, the side, away from the overturning structure, of the connecting frame is provided with a first pushing member and a second pushing member, the first pushing member and the second pushing member are arranged in parallel, the first pushing member and the second pushing member are connected at positions close to the two ends of the connecting frame respectively, the extension directions of the output ends of the first pushing member and the second pushing member are opposite, and the output ends of the first pushing member and the second pushing member are fixedly connected with the two clamping plates respectively, and the first pushing member and the second pushing member jointly drive the two clamping plates to move close to or away from each other.

[0012] By adopting the above scheme, in the process that the first pushing member and the second pushing member drive the two clamping plates to move close to or away from each other, the two supporting rods slide along the slide bar synchronously, the purpose of supporting the two clamping plates is achieved, the stress of the first pushing member and the second pushing member is dispersed, and the service life of the first pushing member and the second pushing member is enhanced.

[0013] Further, the side, away from the overturning structure, of the connecting frame is provided with a first pushing member and a second pushing member, the first pushing member and the second pushing member are arranged in parallel, the first pushing member and the second pushing member are connected at positions close to the two ends of the connecting frame respectively, the extension directions of the output ends of the first pushing member and the second pushing member are opposite, and the output ends of the first pushing member and the second pushing member are fixedly connected with the two clamping plates respectively, and the first pushing member and the second pushing member jointly drive the two clamping plates to move close to or away from each other.

[0014] By adopting the above scheme, the setting of the buffer plate can avoid that the clamping force between the two clamping plates is too large to cause the buffer plate to be extruded and deformed.

[0015] Further, each of the fixing assemblies comprises a placing rod and an elastic member, the placing rod is fixedly connected with the side wall of the clamping plate, placing grooves are formed at the two ends of the placing rod, and one elastic member is connected in each of the placing grooves, the sides, away from each other, of the two elastic members are fixedly connected with fixing plates, and the two fixing plates jointly clamp the buffer plate.

[0016] By adopting the above scheme, two fixed plates are pulled in directions away from each other, and the two elastic members are elongated under the driving of the fixed plates. At this time, the distance between the two fixed plates is larger, and the buffer plate can be placed between the two fixed plates. Because the elastic members have elasticity, after the buffer plate is placed between the two fixed plates, the two elastic members are retracted under the elastic action of themselves, and then the two fixed plates are pulled in directions close to each other, so as to complete the clamping of the buffer plate.

[0017] Further, the side of each of the two fixed plates close to each other is fixedly connected with a plurality of thimbles, and each thimble is inserted and matched with a corresponding anti-dropping groove on the side of the buffer plate.

[0018] By adopting the above scheme, when the two fixed plates clamp the buffer plate, each thimble is inserted and matched with a corresponding anti-dropping groove, which can avoid the buffer plate from falling off between the two fixed plates due to road bumps during transportation of the transportation device.

[0019] Further, the circumferential side of the inner wall of each anti-dropping groove is provided with an anti-skid line.

[0020] By adopting the above scheme, the anti-skid line increases the friction between the thimble and the inner wall of the anti-dropping groove.

[0021] Further, the groove of each anti-dropping groove is provided with a bevel inclined from the groove bottom to the groove opening.

[0022] By adopting the above scheme, the bevel facilitates the insertion of the thimble into the anti-dropping groove.

[0023] In summary, the present application has the following technical effects:

[0024] 1. By setting the clamp, the material is placed between the two clamping plates, and the two clamping plates can clamp the material. Because the driving member is provided, the driving member can drive the clamping structure to rotate, and the clamping structure rotates the material. Therefore, during the transportation of the transportation device, the position of the material can be adjusted in time, and the overall efficiency of PET production is improved.

[0025] 2. By setting the buffer plate, the clamping force between the two clamping plates can be avoided to be too large to cause the buffer plate to be deformed by extrusion.

[0026] 3. By setting the elastic member, after the buffer plate is placed between the two fixed plates, the two elastic members are retracted under the elastic action of themselves, and then the two fixed plates are pulled in directions close to each other, so as to complete the clamping of the buffer plate.
