Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to an intelligent conveyor for industrial food processing. Background Technology

[0002] Food conveyors are mainly used for transporting food raw materials or finished products. They come in various types, including belt conveyors, chain conveyors, mesh belt conveyors, and stainless steel belt conveyors. Some are inclined, and others have cleaning functions. Food conveyors are simple in structure, easy to maintain, have low energy consumption, and low operating costs. They are widely used in food, beverage, and fruit processing, filling, can production, cleaning, PET bottle blowing, and hardware parts manufacturing. Chain conveyors are available in POM, PVC, and 304 / 306 stainless steel. Complete machine designs include straight lines, single-row turning, multi-row, and partitioned lifting types. Food conveyors use specialized food-grade conveyor belts. It can meet the requirements of industries such as food, pharmaceuticals, and daily chemicals. The conveyor belt is made of various materials such as rubber, canvas, PVC, and PU. In addition to conveying ordinary materials, it can also convey materials with special requirements such as oil resistance, corrosion resistance, and antistatic properties. Furthermore, accessories such as push plates, side baffles, and skirts can be added to the conveyor belt to meet the requirements of different processes. The food conveyor provides smooth transport with no relative movement between the material and the conveyor belt, which can avoid damage to the conveyed items. Compared with other conveyors, it has lower noise and is more suitable for occasions where a quiet working environment is required.

[0018] This invention provides an intelligent conveyor for industrial food processing. It has the following advantages:

[0019] 1. This invention isolates food from the main conveyor belt by laying a thin film layer on the outside of the main conveyor belt, which can prevent the main conveyor belt surface from having residual debris and food residue, thus avoiding unsanitary problems. At the same time, the film layer can be replaced according to different types of food being conveyed, so as to avoid the problem of residual debris coming into contact with food and affecting the food safety when conveying different types of food.

[0020] 2. The present invention achieves the effect of pressing the two ends of the pressing plate by cooperating with the clamping strip and the extrusion shell, thereby pressing the two ends of the pressing plate and improving the pressing and limiting effect and stability of the film layer.

[0021] 3. When installing the film, the electric push cylinder 2 extends and presses down and pushes the clamping plate laterally, so that the clamping plate presses one end of the film. Then, the clamping plate is transported to the bottom of the shell by the conveyor and drives the film layer to move.

[0022] 4. This invention can achieve automatic film feeding and pressing operations by cooperating with the laying component and the pressing component. When the conveyor conveys the film in one revolution and closes it, the motor rotates to drive the cutting blade to move downward and cooperate with the cutting table to cut the film, thus realizing the automatic laying and breaking of the film.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides an intelligent conveyor for industrial food processing, comprising a frame 1 and a main conveyor belt 2. The frame 1 is equipped with a main roller, a driven roller, and a support cylinder. One end of the main roller is connected to the power transmission system of the conveyor to drive the main roller to rotate. The main conveyor belt 2 is fitted onto the main roller and the driven roller. An annular film layer 3 is fitted onto the outer surface of the main conveyor belt 2. The same end of the main roller, the driven roller, and the support cylinder respectively penetrates the frame 1 on that side. The ends of the main roller, the driven roller, and the support cylinder that extend out of the frame 1 are fitted together with a side conveyor belt 4. A pressing assembly 5 is installed on the outer side of the side conveyor belt 4. The pressing assembly 5 includes several mounting seats 51 that are equidistantly arranged around and fixedly installed on the outer surface of the side conveyor belt 4 and an extrusion shell 53 located on the outer side of the side conveyor belt 4. A pressing plate 52 is rotatably connected to the surface of the mounting seat 51 through a torsion spring shaft. A cylinder 58 is fixedly connected to the center of the extrusion shell 53. The driving end of the cylinder 58 is fixedly connected to the frame 1.

[0039] Specifically, before installation, the cylinder 58 is extended to misalign the extrusion shell 53 with the clamping plate 52. The clamping plate 52 rotates away from the main conveyor belt 2 due to the torque of the torsion spring shaft, thus opening the clamping plate 52 to facilitate the laying of the film layer 3 and making it easier to clean the clamping plate 52 later. After the film layer 3 is laid on the main conveyor belt 2, the cylinder 58 retracts, causing the extrusion shell 53 to move towards the clamping plate 52, thereby pushing the clamping plate 52 to rotate closer to the main conveyor belt 2 until the clamping plate 52 presses the film layer 3 firmly onto the main conveyor belt 2, thus fixing the film layer. The effect of layer 3 is that the main roller drives the main conveyor belt 2 to rotate while simultaneously driving the side conveyor belt 4 to rotate, thereby causing the pressing plate 52 to rotate synchronously and continuously press the film layer 3, improving the pressing effect on the film and preventing the film from being pulled and damaged. By laying the film layer 3 on the outside of the main conveyor belt 2, this device can avoid residual debris and food residue on the surface of the main conveyor belt 2, which would lead to unsanitary problems. At the same time, the film layer 3 can be replaced according to the different types of food being conveyed, avoiding the problem of residual debris coming into contact with the food and affecting the food safety when conveying different types of food.

[0040] Please see the appendix Figure 3 -Appendix Figure 5 Based on the above embodiments, since the extrusion shell 53 unidirectionally extrudes the pressing plate 52, the pressing effect of the area of ​​the pressing plate 52 away from the extrusion shell 53 on the film layer 3 is limited. Therefore, this embodiment proposes the following solution to solve the above problem: the mounting base 51 includes a base 511, and a groove is formed on the upper surface of the base 511. A sliding seat 512 is slidably connected to the groove. An elastic element 513 is fixedly connected to the opposite side of the sliding seat 512 and the groove. The elastic force of the elastic element 513 is greater than the torque of the torsion spring shaft, so that when the pressing plate 52 is extruded, it first rotates downward and then moves laterally. The elastic element 513 can be... Steel leaf springs, helical springs, torsion bar springs, rubber springs, etc., with helical springs being preferred. Universal balls 514 are fixedly installed at both ends of the clamping plate 52 on the opposite side of the main conveyor belt 2. The clamping assembly 5 includes an annular baffle 54 fixedly installed on the outside of the frame 1. The baffle 54 and the mounting base 51 are located on both sides of the frame 1. An annular retaining strip 55 is fixedly connected to the side wall of the baffle 54. When the clamping plate 52 rotates horizontally, the universal balls 514 on its surface fit against the inner side wall of the retaining strip 55. The extrusion shell 53 includes an outer shell 531. A pressure plate body 532 for pushing the sliding seat 512 to move laterally is fixedly installed inside the outer shell 531.

[0041] Specifically, the extrusion shell 53 presses the clamping plate 52 flat by abutting against the universal ball 514. Before the extrusion shell 53 presses the clamping plate 52, the sliding seat 512 moves away from the baffle 54 by the pulling force of the elastic element 513. When the extrusion shell 53 presses the clamping plate 52 to a horizontal position, the end of the clamping plate 52 near the baffle 54 is misaligned with the retaining strip 55. Then, as the extrusion shell 53 continues to move, the sliding seat 512 is pushed to move by the pressure plate body 532, so that one end of the clamping plate 52 abuts against the baffle 54 and is inserted into the retaining strip 55. The universal ball 514 abuts against the inner wall of the retaining strip 55, thereby achieving the effect of pressing the other end of the clamping plate 52. This results in both ends of the clamping plate 52 being pressed, improving the pressing and limiting effect and stability of the film layer 3.

[0042] Please see the appendix Figure 6 -Appendix Figure 7 The upper surface of the extrusion shell 53 has a cutting opening 533, dividing a portion of the outer shell 531 and the pressure plate body 532. The outer shell 531 is divided into a smaller sliding layer 534 through the cutting opening 533, and the pressure plate body 532 is divided into a smaller pressure plate 537 through the cutting opening 533. The sliding layer 534 is slidably connected to the cutting opening 533. An electric push cylinder 11 is fixedly connected to the side wall of the sliding layer 534, and the drive end of the electric push cylinder 11 is fixedly connected to the outer shell 531. A cutting opening 536 is provided on the surface of sliding layer 534 to divide a partial area of ​​sliding layer 534 and pressure plate 537. Sliding layer 534 is divided into a smaller sliding layer 535 through cutting opening 536. Sliding layer 535 is slidably connected to cutting opening 536. Pressure plate 537 is divided into a smaller pressure plate 538 through cutting opening 536. Electric cylinder 12 is fixedly connected to the upper side wall of sliding layer 534. The driving end of electric cylinder 12 is fixedly connected to sliding layer 535.

[0043] Specifically, before installing the film, the electric pusher cylinder 11 extends and drives the sliding layer 534 to slide outward, so that the clamping plate 52 rotates upward and opens when it reaches the cut 533 to place the film. When laying the film, the conveyor is first controlled to rotate the clamping plate 52 to the cut 536. Then, one end of the film is placed on the main conveyor belt 2 corresponding to the cut 536. Then, the electric pusher cylinder 12 extends and drives the sliding layer 535 to slide towards the side closer to the clamping plate 52. The sliding layer 535 cooperates with the pressure plate 538 to press down and push the clamping plate 52 laterally, so that the clamping plate 52 presses one end of the film. The pressing plate 52 is then transported to the underside of the outer shell 531 via a conveyor, which moves the film layer 3. Then, the electric push cylinder 12 retracts, causing the sliding layer 535 to slide into the inside of the cutting opening 536. The next set of pressing plates 52 is then transported to the cutting opening 536 via the conveyor. By repeating the above operations, the pressing plates 52 can be pressed down on the film in sequence, achieving the effect of quickly installing the film layer 3. After the conveyor rotates once, the electric push cylinder 12 retracts and the electric push cylinder 11 extends, so that the sliding layer 534 and the outer shell 531 form a pressing shell 53, thereby making the pressing plate 52 continuously press the film layer 3.

[0044] Please see the appendix Figure 8 -Appendix Figure 10Based on the above embodiments, manual film laying is time-consuming and labor-intensive. Therefore, this embodiment provides the following technical solution for intelligent automatic film laying. A mounting frame 6 is fixedly connected to the top of the frame 1. An L-shaped placement groove is formed on the surface of the mounting frame 6. A take-up drum 7 with film wound inside the placement groove is placed inside the groove. A film laying assembly 8 is located below the take-up drum 7. The film laying assembly 8 includes an upper rotating plate 801 and a lower rotating plate 802. The two ends of the upper rotating plate 801 and the lower rotating plate 802 are rotatably connected to the mounting frame 6 via shafts. Guide rollers 803 are rotatably connected to opposite sides of the upper rotating plate 801 and the lower rotating plate 802. A motor 9 is fixedly connected to the outer wall of the mounting frame 6. The motor 9 is a self-locking motor. The drive end of the motor 9 is fixedly connected to the shaft of the upper rotating plate 801. The same ends of the upper rotating plate 801 and the lower rotating plate 802 are connected by a gear mechanism 13. 3 includes two meshing gears, which are respectively fixed on the shaft ends of the upper rotating plate 801 and the lower rotating plate 802. The laying component 8 includes a U-shaped rotating frame 806, with both ends of the rotating frame 806 rotatably connected to the mounting frame 6. A motor 2 10 is fixedly connected to the outer wall of the mounting frame 6, and the drive end of the motor 2 10 is fixedly connected to the shaft of the rotating frame 806. A groove is provided on the surface of the rotating frame 806, and a miniature electric push cylinder 3 807 is fixedly connected to both sides of the groove. A clamping plate 808 is fixedly connected to the drive end of the electric push cylinder 3 807. A cutting blade 816 is fixedly connected to the side wall of the upper rotating plate 801. A cutting table 804 is provided below the cutting blade 816. Both ends of the cutting table 804 are fixedly connected to the mounting frame 6. An upper support platform 805 and a lower support platform 809 are provided between the cutting table 804 and the lower rotating plate 802. Both ends of the upper support platform 805 and the lower support platform 809 are fixedly connected to the mounting frame 6.

[0045] Specifically, the two ends of the winding drum 7 with the film wound are placed in the placement groove. Then, one end of the film is passed through the upper rotating plate 801 and the lower rotating plate 802 for limiting. To facilitate the film passing through, the upper rotating plate 801 is rotated by motor 9. The upper rotating plate 801 drives the lower rotating plate 802 to rotate through the gear mechanism 13, so that the upper rotating plate 801 and the lower rotating plate 802 rotate relative to each other, thereby increasing the distance between them to facilitate the worker's film installation. Then, motor 9 rotates in the opposite direction to make the two guide rollers 803 rotate to maintain the minimum distance. The guide rollers 803 guide the film. After the film passes through the gap between the two guide rollers 803, it is placed on the upper support platform 805. First, motor 10 drives the cutting blade 816 to rotate temporarily upward to avoid interfering with the rotation of the rotating frame 806. Then, motor 10 drives the rotating frame to rotate. Rotation of 806 causes the rotating frame 806 to rotate above the upper support platform 805 while maintaining a certain gap. The extension of electric push cylinder 807 drives the clamping plate 808 to move, and the two clamping plates 808 close to clamp the film above the upper support platform 805. After clamping, the motor 10 rotates in the opposite direction to the other side and pulls the film out through the clamping plate 808, so that one end of the film passes through the area corresponding to the cutting opening 536. Through cooperation with the pressing component 5, automatic film feeding and pressing operations can be realized. After the pressing plate 52 presses the front end of the film, the electric push cylinder 807 retracts to release the clamping of the film. When the conveyor completes one revolution and the film is laid and closed, the rotation of motor 10 drives the cutting blade 816 to move downward and cooperate with the cutting table 804 to cut the film. This realizes intelligent automatic film laying without manual laying.

[0046] Please see the appendix Figure 11 -Appendix Figure 12 Based on the above embodiments, since the film is laid flat on the upper support platform 805, the clamping effect of the clamping plate 808 on the film is limited. In order to grasp the film more accurately, this example provides the following technical solution: an electric push cylinder 810 is fixedly connected to the center of the lower support platform 809, and a connecting layer 811 is fixedly connected to the driving end of the electric push cylinder 810. Two top plates 812 are symmetrically fixedly connected to the upper surface of the connecting layer 811 along the center. The two top plates 812 penetrate the upper support platform 805. The two sides of the lower surface of the connecting layer 811 are respectively fixedly connected to... An airbag 814 is connected to the upper support platform 805, which has a cavity 815 inside. The cavity 815 is located between two top plates 812. Several air vents 813 are opened on the top of the cavity 815. Several air vents are provided on the surface of the airbag 814. The air vents are connected to the cavity 815 through the delivery pipe 14. The clamping plate 808 includes a vertical plate 8081. Several elastic telescopic rods 8082 are fixedly connected to the upper side wall of the plate 8081. A clamping piece 8083 is fixedly connected to the end of the elastic telescopic rod 8082 away from the plate 8081.

[0047] Specifically, the extension of the electric cylinder 810 causes the connecting layer 811 to rise, allowing the top plate 812 to pass through the upper support platform 805 and lift the film, causing it to bulge. When the film needs to be clamped, the rotating frame 806 is first rotated above the upper support platform 805. Then, the electric cylinder 810 is controlled to retract, causing the top plate 812 to descend. Simultaneously, the airbag 814 descends, and the connecting layer 811 and the lower support platform 809 work together to compress the airbag 814. The airflow inside the airbag 814 enters the cavity 815 through the delivery pipe 14 and then flows upward through the air outlet 813. The film layer 3 is blown up. At the same time, the plate 8081 is moved towards the top plate 812 by the electric push cylinder 3 807, so that the clamping piece 8083 abuts against the top plate 812. Through the extrusion force, the elastic telescopic rod 8082 gradually retracts. When the height of the top plate 812 is lower than that of the clamping piece 8083, the clamping piece 8083 is stretched by the elastic force of the elastic telescopic rod 8082 and can clamp the blown film. At the same time, the electric push cylinder 3 807 is controlled to extend so that the two clamping pieces 8083 close and the elastic telescopic rod 8082 retracts to the minimum amplitude, thereby achieving the effect of stabilizing the film clamping and improving the clamping accuracy of the film.

[0048] Please see the appendix Figure 13 The upper surface of the cutting table 804 is provided with a V-shaped cutting groove 817, which is located on the rotation trajectory of the cutting blade 816. Rubber pads 818 are fixedly provided on both sides of the cutting groove 817.

[0049] When the cutting blade 816 cuts the film, it rotates to the cutting groove 817 through the bottom end of the cutting blade 816 to cut. At the same time, the two sides of the bottom end of the cutting blade 816 cooperate with the rubber pad layer 818 to apply a certain clamping force to the rear end of the broken film and the front end of the wound film to keep them taut. This makes it easier for the rear end and the front end of the film to overlap relatively flat when the clamping plate 52 closes the rear end and the front end of the broken film after one rotation of the conveyor.

[0050] The workflow involves placing both ends of the film-wound roll 7 into the placement slots, then passing one end of the film through the upper rotating plate 801 and the lower rotating plate 802 for positioning. To facilitate film passage, motor 9 drives the upper rotating plate 801 to rotate, which in turn drives the lower rotating plate 802 to rotate via gear mechanism 13. This relative rotation of the upper and lower rotating plates 801 and 802 increases the distance between them, making it easier for workers to install the film. Subsequently, motor 9 rotates in the opposite direction, causing the two guide rollers 803 to rotate. Maintaining a minimum gap, the film is guided by guide roller 803. After passing through guide roller 803, the film is placed on upper support platform 805. First, motor 210 drives the cutting blade 816 to rotate temporarily upward to avoid interfering with the rotation of rotating frame 806. Then, motor 210 drives rotating frame 806 to rotate, so that rotating frame 806 rotates above upper support platform 805 while maintaining a certain gap. Electric push cylinder 31 extends to drive clamping plate 808 to move. The two clamping plates 808 close to clamp the upper support platform 805. After the film above 5 is clamped, the motor 10 rotates 180° in the opposite direction and pulls the film out through the clamping plate 808, so that one end of the film passes through the area corresponding to the cut 536. Then, the electric push cylinder 12 extends and drives the sliding layer 535 to slide towards the side close to the pressing plate 52. The sliding layer 535 cooperates with the pressure plate 538 to press down and push the pressing plate 52 laterally, so that the pressing plate 52 presses one end of the film. Then, the pressing plate 52 is transported to the bottom of the outer shell 531 by the conveyor and pulled. The film layer 3 moves, and then the electric push cylinder 12 retracts, causing the sliding layer 535 to slide into the inside of the cutting opening 536. The next set of pressing plates 52 is then conveyed to the cutting opening 536 by the conveyor. By repeating the above operation, the pressing plates 52 can be pressed down on the film in sequence, achieving the effect of quickly installing the film layer 3. After the conveyor rotates once, the electric push cylinder 12 retracts and the electric push cylinder 11 extends, so that the sliding layer 534 and the outer shell 531 form a pressing shell 53, thereby making the pressing plates 52 continuously press the film layer 3.

[0051] When clamping the film, the rotating frame 806 is first rotated above the upper support platform 805. Then, the electric push cylinder 810 is controlled to retract. The retraction of the electric push cylinder 810 causes the top plate 812 to descend, and at the same time, it causes the airbag 814 to descend. Through the cooperation of the connecting layer 811 and the lower support platform 809, the airbag 814 is squeezed. The airflow inside the airbag 814 enters the cavity 815 through the delivery pipe 14, and then flows upward through the air outlet 813 to blow air into the film layer 3. At the same time, the electric push cylinder 807 drives the plate 8081 to move upward. The top plate 812 moves to the side, causing the clamping piece 8083 to abut against the top plate 812. Under the pressure of the extrusion, the elastic telescopic rod 8082 gradually retracts. When the height of the top plate 812 is lower than that of the clamping piece 8083, the clamping piece 8083 is stretched by the elastic force of the elastic telescopic rod 8082 and can clamp the blown film. At the same time, the electric push cylinder 807 is controlled to extend, so that the two clamping pieces 8083 close and the elastic telescopic rod 8082 retracts to the minimum amplitude, thereby achieving the effect of stabilizing the clamping of the film and improving the clamping accuracy of the film.
