Description

Technical Field

[0001] The present invention relates to the field of industrialized food processing and intelligent manufacturing, and in particular to a packaging plastic box conveying mechanism based on industrialized food processing and intelligent manufacturing. Background Art

[0002] In the field of industrialized food processing and intelligent manufacturing, efficient and precise conveying of plastic packaging boxes is critical to ensuring production continuity and automation. With the rapid development of the food industry, production lines are increasingly demanding on the pace of the packaging process, and traditional box conveying equipment is gradually exposing its many shortcomings.

[0003] At present, the box conveying mechanism used in most food processing production lines is mostly a linear conveying structure. This type of structure can often only realize single-directional conveying. When the box needs to be turned, cached or the conveying path needs to be adjusted, multiple sets of independent steering equipment and cache devices are required. Not only does it take up a large amount of production space, but it is also easy to reduce the conveying efficiency due to connection problems between equipment, and even cause the box to get stuck, collide, etc., affecting the quality and hygiene safety of food packaging.

[0004] At the same time, existing buffer mechanisms generally suffer from limited storage capacity and poor synchronization of lifting and lowering. During peak production periods, when subsequent processes are temporarily stalled, the boxes cannot be evacuated in time and tend to accumulate on the conveyor belt. However, when subsequent processes speed up, the cached boxes are difficult to supply quickly and orderly, disrupting the rhythm of the production line. Furthermore, traditional push mechanisms have low pushing accuracy, and positioning errors are prone to occur when pushing boxes into or out of the buffer mechanism, causing the boxes to tilt or fall, further affecting production efficiency.

[0005] In addition, in a multi-process collaborative production scenario, the box body needs to be transported in reverse between different processing stations. Traditional reversing mechanisms mostly use chain transmission or direct drive of gear sets, which have problems such as insufficient steering accuracy and poor operating stability. It is difficult to meet the requirements of intelligent manufacturing for high precision and high reliability of conveying equipment.

[0006] Therefore, in order to address the problems of low space utilization, insufficient buffering capacity, poor switching accuracy, and lack of pushing stability in the transportation of packaging plastic boxes in food industrial processing, it is urgent to design a highly integrated, efficient and stable conveying mechanism to meet the automation and intelligent development needs of modern food production lines.

[0031] like Figure 4 As shown, the ejection device 7 has the same structure as the pushing device 5, and the pushing device 5 includes a guide groove seat 51, a guide groove 52, a second screw 53, a movable block 54, a pushing mechanism 55 and a second motor 56; transverse guide grooves 52 are provided at the front and rear positions of the left side interior of the guide groove seat 51, and a second motor 56 is fixedly connected to the center of the right side interior of the guide groove seat 51, and the second motor 56 is a servo motor or a stepping motor; the second screw 53 is movably connected to the center of the left side interior of the guide groove seat 51, and the right center of the second screw 53 is fixedly connected to the left output shaft of the second motor 56; the front and rear exteriors of the movable block 54 are respectively movably connected to the corresponding guide groove 52, the threaded hole arranged in the center of the movable block 54 is connected to the second screw 53, and a pushing mechanism 55 is provided on the movable block 54.

[0034] Wherein, the motor three 61 is a servo motor or a stepping motor; the input belt 4 and the output belt 8 are both conveyor belts.

[0035] The use state of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost, and easy installation. In the initial state, the rotating seat 2 is movably connected to the upper side of the fixed seat 1 through the reversing mechanism 6, and several lifting and caching mechanisms 3 around the outside are in a waiting state. The input belt 4 starts to convey the packaging plastic box body. When the box body is conveyed to the upper right side position of the input belt 4, the pushing device 5 is started, and the motor 2 56 of the pushing device 5 runs, driving the screw 2 53 to rotate. Since the threaded hole in the center of the movable block 54 is connected to the screw 2 53, and the front and rear parts of the movable block 54 are movable in the guide groove 52 of the guide groove seat 51, the movable block 54 moves from right to left along the guide groove 52. When the movable block 54 moves to the appropriate position, the pushing mechanism 5 The two cylinders 551 of 5 extend and push the pushing plate 552 to move downward until the pushing plate 552 is located on the left side of the box body. Then, under the drive of the motor 2 56, the movable block 54 continues to move to the right and pushes the box body onto the placement table 32. After the pushing is completed, the cylinder 551 contracts and drives the pushing plate 552 to reset. The motor 2 56 reverses and returns the movable block 54 to the initial position. After the box body enters the lifting cache mechanism 3, if caching is required, the synchronous lifting mechanism 33 starts to work, the motor 1 333 is started, and its output shaft drives the screw 1 334 connected to it to rotate. Through the transmission of the pulley 335 and the synchronous belt 336, the other screw 1 334 rotates synchronously, and the slider 332 cooperates with the screw 1 334 in the slide groove 331. As the screw 1 334 rotates, the slider 332 drives the placement table 32 to move downward, and the box body is stored in the storage slot 31. The protective plate 35 prevents the box body from falling from the outside. When the cached box body needs to be sent out, the motor 3 61 of the reversing mechanism 6 is started, driving the driving gear 63 to rotate. The driving gear 63 engages with the internal gear 62, so that the internal gear 62 drives the rotating base 2 to rotate around the fixed base 1, and the lifting cache mechanism 3 with the box body is rotated to the corresponding position of the ejection device 7 on the right side. Then the motor 1 333 is reversed, the placement table 32 moves upward, and the box body is transported to the upper opening of the storage slot 31. Then the ejection device 7 starts to work. Its structure is consistent with that of the pushing device 5. The motor 2 56 drives Screw 2 53 rotates to move the movable block 54 to the left, and the cylinder 551 of the pushing mechanism 55 extends to drive the pushing plate 552 to move down and insert into the insertion slot 34 on the left side of the box body. Then the movable block 54 moves to the right, pushing the box body out of the storage slot 31 of the lifting and caching mechanism 3, and the box body is pushed onto the output belt 8, which conveys the box body to the next process. After that, the various components of the pushing device 7 are reset. During the whole process, the input belt 4 continues to convey the box body to the left, and the output belt 8 continues to convey the box body to the right. The lifting and caching mechanism 3 can temporarily store the box body according to actual needs. The rotation of the rotating seat 2 realizes the conversion of the box body conveying direction. The various devices cooperate tacitly to ensure the high efficiency and stability of the packaging plastic box conveying.
