Description

Technical Field

[0001] The invention belongs to the field of emery roller sand bonding machines, and particularly relates to a novel emery roller sand bonding machine for peeling fruits and vegetables. Background Art

[0002] In the field of fruit and vegetable processing, emery rollers are the core equipment for achieving efficient skin removal of fruits and vegetables. Their peeling effect (such as the skin residue rate and the degree of pulp damage) and quality stability (such as service life and performance consistency between batches) are directly related to the production efficiency and product quality of fruit and vegetable processing companies. In the production and manufacturing process of emery rollers, parameters such as the adhesion density, distribution uniformity, and bonding strength of the gravel on the surface of the emery rollers will directly affect its peeling effect and durability for different fruits and vegetables (such as potatoes, carrots, apples, etc.) in actual production.

[0003] At present, the traditional sand bonding process of sand rollers mainly relies on manual operation. The specific process is: after the sand roller workpiece is coated with glue, the workpiece is manually moved up and down and rotated to make it contact with the gravel to complete the sand bonding. However, the workpiece needs to be rotated and moved manually one by one, which is time-consuming and labor-intensive, and it is difficult to meet the needs of large-scale production. In addition, the controllability of manual operation is insufficient, resulting in uneven sand bonding quality. Since it is difficult to maintain a constant manual rotation angle and force, the sand adhesion uniformity on the sand roller surface is poor, the product quality consistency is low, and the subsequent quality inspection and rework costs are increased. Summary of the Invention

[0015] Beneficial effects of the present invention: 1. The fourth electric cylinder in the pulling mechanism drives the moving block to drive the ejector rod to pull the slide backward, compressing the spring in the groove and causing the slide to completely retract into the second ram. At this time, the positioning groove at one end of the sand-bonding roller is aligned with the first ram and inserted. Then, the pulling force of the pulling mechanism is released, and the spring resets and pushes the slide to accurately embed into the positioning groove at the other end of the sand-bonding roller, forming a two-way positioning structure with spring pre-tightening and slide plug-in. Compared with the tedious operation of manually aligning workpieces one by one, this process achieves automatic clamping in seconds through mechanical linkage. Combined with the continuous operation of the drive mechanism, it can realize assembly line batch processing of sand-bonding rollers, completely solving the problem of time-consuming and labor-intensive manual operation and difficulty in meeting large-scale production requirements. 2. After the drive mechanism is started, the servo motor drives the rotating rod to rotate through the synchronous belt. The eccentric disks at both ends of the rotating rod are hinged to the hinge rod through the eccentric shaft, driving the movable arm to swing back and forth around the rotating shaft. At the same time, the second slide on the movable arm slides along the rotating shaft, causing the sand-bonding roller to synchronously produce lateral displacement during the swinging process, forming a composite motion trajectory of rotation, swinging and translation. This motion mode causes each area of the sand-bonding roller surface to be immersed in the sand-bonding box of the sand-bonding mechanism at a constant angle and force, avoiding the accumulation of sand or leakage caused by uneven rotation angle and force fluctuation during manual operation. 3. The output shaft of the second electric cylinder extends into the cylindrical groove to lock the sliding column position. The spring preload ensures that the sand-bonding roller does not move axially during movement. The movable arm adaptively adjusts the swing amplitude by sliding in the second slide groove, so that the sand-bonding roller always maintains the ideal contact depth with the sand-bonding box. Ultimately, the sand adhesion density and distribution uniformity are controlled within ±2%, significantly improving product quality consistency and reducing subsequent quality inspection and rework costs. 4. The right-angled triangle stable structure formed by the sliding rod and the sleeve frame in the constraint mechanism, in conjunction with the electric cylinder of the adjustment mechanism, can accurately adjust the opening angle of the movable arm, constraining the swing angle of the movable arm, making it convenient to stick sand to rollers of different sizes; 5. The cooperation between the guide rail and the roller in the moving mechanism enables the bearing block to move laterally to adjust the sand sticking position and adapt to the layout requirements of sand sticking boxes of different specifications. The limiting mechanism drives the second block to rise and fall through the third electric cylinder, forming a radial clamp for the sand sticking roller with the first block, further preventing it from shifting during the compound movement.

[0030] Working principle: When in use, the sliding column 805 is first pulled by the pulling mechanism, which activates the fourth electric cylinder 16 fixed to the other movable arm 8. Its output shaft drives the moving block 17 to move the ejector rod 806, compressing the spring 804 in the groove 803 on the second ejector head 802, and the sliding column 805 is completely retracted into the second ejector head 802; Then, align the positioning groove at one end of the sand-bonding roller 30 with the first head 801 and insert it. After releasing the tension of the fourth electric cylinder 16, the spring 804 resets and pushes the slide post 805 to accurately fit into the positioning groove at the other end of the sand-bonding roller 30, forming a two-way positioning structure with the spring 804 pre-tightening and the slide post 805 plugged in. Then, the output shaft of the second electric cylinder 807 extends into the cylindrical groove 808 of the slide post 805 to lock the position, ensuring that the sand-bonding roller 30 has no axial movement during movement. After the driving mechanism is started, the output shaft of the servo motor 24 drives the rotating rod 4 to rotate through the first synchronous pulley 25, the synchronous belt body 27 and the second synchronous pulley 26. The eccentric disks 5 at both ends of the rotating rod 4 are hinged to the hinge rod 10 through the eccentric shaft, driving the movable arm 8 to swing back and forth around the rotating shaft 7. At the same time, the second slide groove 9 on the movable arm 8 slides along the rotating shaft 7, causing the sand-bonding roller 30 to synchronously generate lateral displacement during the swinging process, forming a composite motion trajectory of rotation, swinging and translation; When the sand-bonding roller 30 moves downward, it enters the sand-bonding box 28 and picks up the sand. In the moving mechanism, the second base plate 101 is fixed to the side wall of the first base plate 1, and the guide rail 102 at the upper end cooperates with the roller 105 at the lower end of the fixed plate 103 to allow the bearing block 106 to move laterally, thereby adjusting the position of the bearing block 106; When the sand-bonding roller 30 needs to be installed, the bearing block 106 can be used to support the sand-bonding roller 30, and then the limit mechanism is opened. By opening the third electric cylinder 12, the lifting block 13 drives the second stopper 14 to slide in the limit groove 15, forming a radial clamping of the sand-bonding roller 30 with the first stopper 11 to prevent it from deflecting during the compound movement; When in use, the operating angle of the movable arm 8 can also be constrained. In the constraint mechanism, the movable shaft 601 is rotatably mounted on the two second U-shaped blocks 6, the sleeve 603 is sleeved on the side wall of the movable shaft 601, and the slide rod 604 is slidably arranged in the first slide groove 602 of the movable arm 8 and fixedly connected to the third U-shaped block 605. When the slide rod 604 is located in the center of the first slide groove 602, the movable arm 8, the second U-shaped block 6 and the sleeve 603 form a right-angled triangle stable structure to constrain the swing angle of the movable arm 8. The first electric cylinder 607 of the adjustment mechanism is fixed to the first set block 606 on the side wall of the movable shaft 601. Its output shaft accurately adjusts the position of the slide rod 604 through the second set block 608, thereby adjusting the opening angle of the movable arm 8 to accommodate rollers of different sizes. In the reinforcement mechanism, the two movable arms 8 are connected by a threaded column 18, the fifth electric cylinder 21 is fixed to the third set block 20 and drives the block 22 to press against the movable shaft 601, and cooperates with the fixing effect of the nut 23 to enhance the connection stability between the movable arm 8 and the movable shaft 601. Finally, the sand-sticking roller 30 is immersed in the sand-sticking box 28 in turn at a constant angle and force in the compound motion, so as to achieve uniform adhesion of sand and gravel and complete the sand-sticking operation.
