Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding processing equipment, in particular to horizontal rotational molding equipment. Background Technique

[0002] Rotational molding is a plastic processing technology. After uniformly heating and melting plastic particles or powders, they are roll-pressed and formed in a specific mold to finally obtain the required plastic products. Rotational molding equipment is used to manufacture polymer products and is usually used to produce plastic products. The rotational molding equipment manufactures plastic products of various shapes and sizes by pressing heated plastic materials into the mold and then cooling and shaping.

[0003] At present, during the processing of rotational molding equipment on the market, in order to adapt to different process requirements, it is necessary to adjust and replace the rotational molding barrel. Since most rotational molding equipment uses a fixed clamping method to fix the rotational molding barrel, this fixing method limits the user's ability to flexibly adjust according to the actual size of the rotational molding barrel. In addition, considering the differences in weight among rotational molding barrels of different sizes, when the rotational molding barrel is installed at a higher position, it undoubtedly increases the working difficulty and potential safety risks of the operator. Therefore, the utility model provides horizontal rotational molding equipment to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and the proposed horizontal rotational molding equipment can, after the fixing mechanisms are movably arranged on both sides of the upper end surface of the base, drive the fixing mechanisms to move and adjust through a bidirectional screw under the action of a first servo motor, so as to clamp and fix rotational molding barrels of different specifications and sizes. At the same time, the support mechanisms movably arranged on both sides of the upper end surface of the base can support the rotational molding barrel placed at the upper end, thereby reducing the working difficulty of the operator.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] The horizontal rotational molding equipment includes a base. A bidirectional screw is rotatably arranged at the midpoints of the inner walls on both sides of the base. Fixing mechanisms are threadedly sleeved on both sides of the outer surface of the bidirectional screw. One side of one of the two fixing mechanisms is fixedly provided with an adjusting plate at the upper end. A movable block is movably arranged on the upper end surface of the adjusting plate, and a second servo motor is fixedly arranged on the upper end surface of the movable block;

[0007] Sliding rods are fixedly arranged at the front end and the rear end of the upper end surface of the base. Support mechanisms are slidably arranged on both sides of the outer surfaces of the two sliding rods. The two fixing mechanisms both include clamping plates, fixing plates, sliding blocks and clamping parts. The two support mechanisms both include support plates, two electric telescopic rods, a plurality of rotating blocks and movable plates;

[0008] Through the above technical solution, the bidirectional screw rotatably arranged on the inner walls of both sides of the base drives the fixed mechanism sleeved with threads under the drive of the first servo motor to move and adjust, so that the rotational molding barrel placed on the upper end surface of the support mechanism can be clamped and fixed. At the same time, a threaded rod is rotatably arranged in the adjusting plate fixedly arranged on one side of a fixed mechanism, which can drive the movable plate and the second servo motor to move and adjust, so that the cross-shaped insertion block fixed at the output end of the second servo motor can be inserted and connected with one side of the rotational molding barrel, and starting the second servo motor can drive the rotational molding barrel to rotate.

[0009] Furthermore, the clamping plate is hinged to one side of the upper end surface of the fixing plate, the clamping member is fixedly arranged at the connection between the clamping plate and one side of the fixing plate, and the fixing plate is fixedly arranged on the upper end surface of the sliding block;

[0010] Through the above technical solution, after the clamping plate and the fixing plate are hinged, the rotational molding barrel clamped on the upper end surface of the fixing plate can be clamped and fixed to prevent the rotational molding barrel from falling off. At the same time, the bidirectional screw can drive the sliding block to move and adjust.

[0011] Furthermore, fixed rods are fixedly arranged at the front end and the rear end of the inner walls of both sides of the base, and the sliding block is movably sleeved on the outer surfaces of the two fixed rods and the bidirectional screw;

[0012] Through the above technical solution, the two fixed rods fixedly arranged can play an auxiliary role in the movement and adjustment of the sliding block.

[0013] Furthermore, a plurality of the rotating blocks are rotatably arranged inside the upper end surface of the support plate, two electric telescopic rods are respectively fixedly arranged on both sides of the lower end surface of the support plate, and the movable plate is fixedly arranged on the lower end surfaces of the two electric telescopic rods;

[0014] Through the above technical solution, after a plurality of rotating blocks are rotatably arranged on the upper end surface of the support plate, while supporting the rotational molding barrel, it can also play an auxiliary role in rotating the rotational molding barrel. At the same time, the rotational molding barrel placed on the upper end surface of the support plate can be adjusted in height under the action of the electric telescopic rods.

[0015] Furthermore, the front end and the rear end of the lower end surface of the movable plate are respectively sleeved on the outer surfaces of two sliding rods, and the two support mechanisms are movably arranged between the two fixed mechanisms;

[0016] Through the above technical solution, after the support mechanism is slidably arranged on the outer surfaces of the two sliding rods through the movable plate, the support mechanism can be pushed to move and adjust according to requirements. After the support mechanism is arranged between the fixed mechanisms, the height of the rotational molding barrel can be adjusted first, and then the rotational molding barrel can be fixed by the fixed mechanism.

[0017] Further, threaded rods are rotatably arranged at the midpoints of the inner walls on both sides of the adjusting plate. The threaded rods and the lower ends of the movable blocks are threadedly sleeved. A bottom plate is fixedly arranged at the lower end of one side of the base. A first servo motor is fixedly arranged on the upper end surface of the bottom plate. The output end of the first servo motor is fixedly connected to one side of a bidirectional screw;

[0018] Through the above technical solution, the threaded rods rotatably arranged in the adjusting plate can drive the movable blocks fixed with the second servo motor to move and adjust. The first servo motor fixedly arranged on the upper end surface of the fixedly arranged bottom plate can drive the bidirectional screw to rotate.

[0019] Further, a rotomolding barrel is rotatably and snap-connected between the upper ends of the two fixing mechanisms. A cross-shaped embedding block is fixedly arranged at the output end of the second servo motor. The cross-shaped embedding block is fitted and connected with one side of the rotomolding barrel;

[0020] Through the above technical solution, after the rotomolding barrel is rotatably and snap-connected to the upper end of the fixing mechanism, the second servo motor can be fitted with the rotomolding barrel through the cross-shaped embedding block to drive the rotomolding barrel to rotate.

At the same time, the two fixedly arranged electric telescopic rods can adjust and move the position height of the placed rotomolding barrel, so as to effectively adjust and support different sizes of rotomolding barrels.

[0023] 2. For the horizontal rotomolding equipment proposed by the utility model, by rotatably arranging a bidirectional screw at the midpoints of the inner walls on both sides of the base, it can drive the two fixing mechanisms sleeved with threads to move and adjust during rotation.

[0038] Working principle: When in use, first, the operator can move the two support mechanisms 7 according to the size of the rotational molding barrel 5 to be used. After adjustment, the rotational molding barrel 5 is placed on the upper ends of the two support mechanisms 7. Starting the electric telescopic rod 702 can drive the rotational molding barrel 5 to adjust its height.
