[0023] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described.

[0024] As Figures 1-3 shown, a trimming mechanism for the skin of a plastic suction bathtub includes a bathtub body 1 and a cutting part 11 provided on the bathtub body 1, and further includes:

[0025] A bottom plate 5, which is provided with a second chute 51 along its edge, and the bathtub body 1 is fixed on the bottom plate 5;

[0026] A clamping unit 4, which is symmetrically arranged on the bottom plate 5 and cooperates with the bathtub body 1;

[0027] A support frame 30, which is slidably arranged in the second chute 51, and a cutting unit 31 and a transmission unit 32 are arranged on the support frame 30. The cutting unit 31 includes a cutting blade 312, a first motor 310 and a slide block 311 slidably arranged on the support frame 30. The first motor 310 is fixed on the slide block 311, and its output end cooperates with the cutting blade 312. The transmission unit 32 controls the sliding of the slide block 311 so that the cutting blade 312 approaches the cutting part 11.

[0028] Specifically, the bathtub body 1 is an acrylic bathtub, and the cutting part 11 is the surplus material produced during the production of the bathtub body 1. The bathtub body 1 is placed at the center of the bottom plate 5 and fixed by the clamping unit 4. The first motor 310 controls the rotation of the cutting blade 312, and at the same time the transmission unit 32 controls the slide block 311 to slide in the first chute 302, so that the cutting blade 312 approaches and contacts the cutting part 11 of the bathtub body 1, and the support frame 30 slides along the second chute 51, that is, around the bottom plate 5 for one circle, removing the cutting part 11 of the bathtub body 1. The automatic sliding cutting method improves the cutting efficiency and also ensures the flatness of the cutting surface of the bathtub body 1.

[0029] As a further embodiment provided by the present utility model, the transmission unit 32 includes a transmission wheel 328, a second motor 326, and a first pulley 323 disposed at the output end of the second motor 326. The second motor 326 is fixed to the support frame 30 through a bracket 325, and a rotating shaft 322 is clamped on its output shaft. The rotating shaft 322 cooperates with the first pulley 323 and the second bevel gear 321. The transmission wheel 328 is rotatably connected to the support frame 30, and a second pulley 327 is rotatably connected to one end of the transmission wheel 328. A synchronous belt 324 is disposed between the first pulley 323 and the second pulley 327. A toothed groove 52 is formed on the bottom plate 5. The transmission wheel 328 meshes with the toothed groove 52. One end of the transmission wheel 328 slides in the toothed groove 52, and the other end cooperates with the second pulley 327. The output of the second motor 326 is used to control the first pulley 323 to rotate the second pulley 327 through the synchronous belt 324, so that the transmission wheel 328 continuously meshes with the toothed groove 52, and the support frame 30 automatically surrounds the bottom plate 5 for one circle to complete the cutting of the bathtub body 1.

[0030] As a further embodiment provided by the present utility model, the cutting unit 31 further includes a first screw 315, a first bevel gear 316, and a second bevel gear 321 meshing with the first bevel gear 316. One end of the first screw 315 cooperates with the first bevel gear 316, and a concave block 314 is disposed at the other end thereof. A spring 313 for pushing the slider 311 is disposed on the concave block 314. The second bevel gear 321 cooperates with the transmission unit 32. When the second motor 326 of the transmission unit 32 operates, the second bevel gear 321 meshes with the first bevel gear 316 to rotate, so as to control the first screw 315 to rotate and drive the concave block 314 to push the slider 311 to slide through the spring 313, so that the cutting blade 312 contacts the bathtub body 1. When the size of the bathtub body 1 changes, the extrusion force of the concave block 314 on the slider 311 can be controlled, so as to adapt to the bathtub body 1 with a small part of the size changed.

[0031] As a further embodiment provided by the present utility model, the clamping unit 4 includes a clamping block 42 fixed to the bottom plate 5. A second screw 41 is rotatably disposed on the clamping block 42. A top block 43 is threadedly connected to the second screw 41. When the bathtub body 1 is placed on the bottom plate 5, the second screw 41 is rotated to continuously move the top block 43 closer to the bathtub body 1 until the bathtub body 1 is fixed to the bottom plate 5.

[0032] As a further embodiment provided by the present utility model, an extrusion block 44 is disposed on the top block 43. The extrusion block 44 is a rubber block. The rubber material improves the effect of the extrusion block 44 and the bathtub body 1, increases the friction force between the two, and makes the bathtub body 1 more firmly fixed to the bottom plate 5.

[0033] As a further embodiment provided by the present utility model, a material cleaning hole 53 is opened at the axis of the bottom plate 5, and an inclined surface 54 is provided on the material cleaning hole 53. After cutting the bathtub body 1, the remaining materials after cutting can be swept into the material cleaning hole 53, improving the efficiency of cleaning waste materials. The inclined surface 54 forms an angle of 30° with the upper plane, causing some waste materials to fall into the material cleaning hole 53 along the inclined surface 54.

[0034] As a further embodiment provided by the present utility model, ball bearings 301 are linearly arrayed on the support frame 30. The ball bearings 301 are located in the second sliding groove 51 and slide therein. The ball bearings 301 are in point contact with the inner surface of the second sliding groove 51. When the support frame 30 slides in the first sliding groove 302, the sliding smoothness of the support frame 30 is improved through the ball bearings 301.

[0035] As a further embodiment provided by the present utility model, a chassis 2 is provided at the bottom of the bottom plate 5. The chassis 2 has four support rods, improving the stability of cutting the bathtub body 1.

[0036] As a further embodiment provided by the present utility model, a protective plate 303 is clamped on the support frame 30. The protective plate 303 is located between the slider 311 and the second belt pulley 327 and is fixed to the support frame 30 through a pin shaft, thereby protecting the first motor 310 and the second belt pulley 327.

[0037] Working principle: First, place the bathtub body 1 on the bottom plate 5. By rotating the second screw rod 41, the top block 43 slides on the second screw rod 41 and approaches the bathtub body 1 until the extrusion block 44 comes into contact with the bathtub body 1, thereby completing the fixation of the bathtub body 1. Then, start the first motor 310 and the second motor 326. The first motor 310 controls the rotation of the cutting blade 312. The first function of starting the second motor 326 is: the second bevel gear 321 is engaged with the first bevel gear 316 through the rotating shaft 322 at the output end of the second motor 326 to synchronously rotate the first screw rod 315, thereby controlling the concave block 314 to slide in the first sliding groove 302, and the cutting blade 312 on the slider 311 is pushed close to the bathtub body 1 through the elastic force of the spring 313 to cut the cutting part 11 of the bathtub body 1. The second function is: when the rotating shaft 322 rotates, it will drive the first belt pulley 323 to rotate, and then the second belt pulley 327 rotates through the synchronous belt 324. Since the transmission wheel 328 at the end of the second belt pulley 327 is engaged in the toothed groove 52, the support frame 30 rotates around the bottom plate 5 for one circle to remove the cutting part 11 of the bathtub body 1. The automated cutting method improves the cutting efficiency and makes the cutting surface of the bathtub body 1 flat, facilitating subsequent grinding.

[0038] The above technical solution of the present utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single. For the parts not involved in the technical solution of this application, they are the same as the prior art or can be implemented using the prior art, and will not be elaborated herein.

[0039] The technical solutions in the above embodiments have clearly and completely described the content of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
