Description

Technical Field

[0001] This utility model relates to the field of rotational molding product processing technology, specifically to rotational molding product cut trimming equipment. Background Technology

[0002] Rotational molding, also known as rotational molding, is a common molding process for hollow thermoplastics. The process involves adding plastic raw material into a mold, which is then rotated and heated along two vertical axes. Under the influence of gravity and heat, the plastic raw material gradually and evenly coats, melts, and adheres to the entire surface of the mold cavity, forming the desired shape. After cooling and solidification, the product is formed.

[0003] Because of their low cost, rotational molding dies can easily produce parts of different sizes within a reasonable cost range. Therefore, they are widely used in the molding process of hollow, double-layer, and complex plastic products. The rotational molded products often require subsequent cutting. However, the existing technology does not have a structure for trimming the cuts, which makes the cuts of the products prone to unevenness, warping, and corner warping, thus affecting the subsequent processing and use of the products.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we proposed a rotational molding product cutting and trimming equipment that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting trimming device for rotational molding products, so as to solve the problem that the prior art mentioned in the background does not have a structure for trimming the cutting, which leads to problems such as unevenness, curling edges, and curling corners of the product cutting, which in turn affects the subsequent processing and use of the product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotational molding product cutting and trimming equipment, including a frame, a fixed frame installed inside the frame, and an mounting frame installed on the fixed frame. A rotating worktable is rotatably mounted on the mounting frame, and a motor driving the rotation of the rotating worktable is installed at the rear end of the rotating worktable. Several inner cylinders are installed on the rotating worktable. Three trimming worktables are arranged on the outside of the rotating worktable on the mounting frame. The three trimming worktables are a large-mouth trimming worktable located at the top, a side-mouth trimming worktable located on both sides, and a small-mouth trimming worktable at the end. Each trimming worktable includes a sliding platform movably mounted on the mounting frame, and several trimming spindles are movably mounted on the sliding platform. The trimming spindle is composed of a driving rotation part and a trimming shaft part.

[0007] Preferably, the end face of the frame is provided with an opening to facilitate the maintenance and adjustment of the internal components of the frame by the staff, and two symmetrically distributed sliding doors are slidably provided at the opening to block the opening when the equipment is in operation, so as to prevent product debris from the cutting and trimming from flying everywhere, which would be inconvenient to clean and could easily cause personal injury.

[0008] Preferably, the end face of the rotary worktable is formed with two protruding plates, and the protruding plates are formed with grooves that are compatible with the inner liner. This allows the inner liner to be snapped into the grooves, which can effectively increase its installation stability.

[0009] Preferably, the sliding platform consists of a drive source, a lead screw, and a sliding seat. The drive source drives the lead screw to rotate, and the sliding seat is threaded to the outside of the lead screw. By driving the lead screw to rotate using the drive source, the sliding seat can be moved along the lead screw, thereby adjusting the distance between the cutting spindle and the inner liner to achieve precise cutting operations.

[0010] Preferably, the drive source is a servo motor, which is mounted on a mounting bracket. By utilizing the advantages of high precision, good stability, and high speed of the servo motor, stable operation of the equipment can be achieved.

[0011] Preferably, symmetrically distributed guide rails are fixedly installed on the end face of the mounting bracket, and the sliding seat is limited to slide on its outer side to increase the sliding stability of the sliding seat and the cutting spindle.

[0012] Preferably, the sliding platform is detachably mounted on the mounting bracket by bolts to facilitate the replacement of the sliding platform model and specifications. Similarly, the cutting spindle is detachably mounted on the sliding seat by bolts to facilitate manual adjustment of the position and height of the cutting spindle according to the change of the sliding platform model and specifications, making the cutting operation more precise.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This rotational molding product cutting and trimming equipment, through the coordinated arrangement of a rotating worktable, an inner liner, and three trimming worktables, uses a motor to drive the rotating worktable to rotate, so that the inner liner is sequentially aligned with the trimming spindles on the three trimming worktables. Then, a sliding platform drives the trimming spindles to move, and the drive rotation unit is activated to make the trimming shaft rotate at high speed, which can grind and trim the trimmed edges of various parts of the product, effectively avoiding problems such as unevenness, warping, and corner warping, which is beneficial to the subsequent processing and use of the product. Specifically... The contents are as follows: (1) By coordinating the rotating worktable, the inner liner and the three cutting worktables, the rotating worktable is driven by a motor to rotate, so that the inner liner on it is aligned with the cutting spindles on the three cutting worktables in sequence. Then, the cutting spindle is moved by the sliding platform, so that the cutting shaft of the cutting spindle contacts the product on the inner liner. At this time, the drive rotation unit is started, so that the cutting shaft rotates at high speed, and the cutting edges of the product can be ground and trimmed, so as to effectively avoid unevenness, warping, and warping of the cutting edges, which is beneficial to the subsequent processing and use of the product.

[0014] The openings on the end face of the frame allow staff to easily inspect and adjust the internal components. The two sliding doors at the openings can be used to seal the openings during operation, preventing product debris from flying everywhere and causing inconvenience in cleaning and potential personal injury.

[0015] By coordinating the drive source, lead screw, and sliding seat, the drive source drives the lead screw to rotate, which in turn moves the sliding seat along the lead screw. This allows for adjustment of the distance between the cutting spindle and the inner liner, enabling precise cutting operations. Furthermore, the drive source uses a servo motor, which leverages the advantages of high precision, good stability, and high speed to ensure stable operation of the equipment.

[0016] By detachably mounting the sliding platform onto the mounting bracket, the model and specifications of the sliding platform can be easily changed. Similarly, by detachably mounting the cutting spindle onto the sliding base, the position and height of the cutting spindle can be manually adjusted according to the change of the sliding platform model and specifications, making the cutting operation more precise.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a rotational molding product cutting and trimming equipment, including a frame 1; a fixed frame 3 is installed inside the frame 1, and an mounting frame 4 is installed on the fixed frame 3. A rotating worktable 5 is rotatably mounted on the mounting frame 4, and a motor driving the rotation of the rotating worktable 5 is provided at the rear end of the rotating worktable 5. Several inner liner 6 are installed on the rotating worktable 5. Two protruding plates are formed on the end face of the rotating worktable 5, and grooves adapted to the inner liner 6 are formed on the protruding plates. In this way, the inner liner 6 can be snapped into the grooves, which can effectively increase its installation stability.

[0026] Furthermore, three trimming worktables are provided on the outside of the rotating worktable 5 on the mounting frame 4. The three trimming worktables are the large-mouth trimming worktable 7 located at the top, the side-mouth trimming worktable 8 located on both sides, and the small-mouth trimming worktable 9 at the end. Each trimming worktable includes a sliding platform 10 movably mounted on the mounting frame 4. Several trimming spindles 11 are movably mounted on the sliding platform 10. The trimming spindle 11 is composed of a drive rotation part and a trimming shaft part.

[0027] In use, the rotating worktable 5 is driven by a motor to rotate, so that the inner liner 6 on it is aligned with the cutting spindles 11 on the three cutting worktables in sequence. Then, the cutting spindles 11 are moved by the sliding platform 10, so that the cutting shaft of the cutting spindle 11 contacts the product on the inner liner 6. At this time, the drive rotation unit is activated, so that the cutting shaft rotates at high speed, which can grind and trim the cutting edges of the product, effectively avoiding problems such as unevenness, warping, and warping of the cutting edges, which is beneficial to the subsequent processing and use of the product.

[0028] In practice, the cycle time of this cutting workstation is 5 seconds for clamping, 20 seconds for cutting, 5 seconds for releasing the clamp, and 20 seconds for the robot to run, for a total of 50 seconds. If dual robot arms are used for loading and unloading, the parallel time can be reduced by 10 seconds, totaling 40 seconds. Six machines are needed to achieve an 8-second cycle time.

[0029] Example 2: Based on Example 1, the end face of the frame 1 is provided with an opening to facilitate the maintenance and adjustment of the internal components of the frame 1 by the staff. Two sliding doors 2 are symmetrically distributed at the opening to block the opening when the equipment is in operation, so as to prevent the product debris from the cutting and trimming from flying everywhere, which would be inconvenient to clean and could easily cause personal injury.

[0030] Furthermore, the sliding platform 10 consists of a drive source, a lead screw 13, and a sliding seat 15. The drive source drives the lead screw 13 to rotate, and the sliding seat 15 is threaded to the outside of the lead screw 13. Through the cooperative arrangement of the drive source, the lead screw 13, and the sliding seat 15, the drive source drives the lead screw 13 to rotate, which in turn drives the sliding seat 15 to move along the lead screw 13. This allows for the adjustment of the distance between the cutting spindle 11 and the inner liner 6, thus achieving precise cutting operations. The drive source is a servo motor 12, which is mounted on the mounting bracket 4. Utilizing the advantages of the servo motor 12, such as high precision, good stability, and high speed, stable operation of the equipment can be achieved.

[0031] In addition, symmetrically distributed guide rails 14 are fixedly installed on the end face of the mounting bracket 4, and the sliding seat 15 is limited to slide on its outer side to increase the sliding stability of the sliding seat 15 and the cutting spindle 11. Furthermore, the sliding platform 10 is detachably installed on the mounting bracket 4 by bolts to facilitate the replacement of the model and specifications of the sliding platform 10. Similarly, the cutting spindle 11 is detachably installed on the sliding seat 15 by bolts to facilitate manual adjustment of the position and height of the cutting spindle 11 according to the replacement of the model and specifications of the sliding platform 10, so as to make the cutting operation more precise.
