Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a servo-driven eight-station canning packaging machine. Background Art

[0002] Packaged products on the market now, such as nuts, snacks, granular seasonings, etc., are packaged in cans for easy storage and transportation, and can be used as gift boxes or some high-end products.

[0003] Most canning and packaging machines on the market use a common motor-frame divider with a complex structure, low positioning accuracy, and complex adjustments. The discharge hopper is fixed, and the opening of the discharge hopper must be a certain distance above the can opening for loading and unloading. This distance causes material to spill outside the can, resulting in unstable packaging weight and defective products. Material can also stick to the can opening, causing poor sealing during the inner capping process, resulting in high defective product production, resulting in canning losses, increased packaging costs, and waste.

[0012] The servo-driven eight-station canning packaging machine enables cans to enter the star tray can feeding trough through the can feeding chain plate. The star tray operates in an intermittent pause mode, rotating one station at a time. Since the star tray can feeding trough is a uniformly distributed slot, each time it rotates one station, the slots on the star tray will be aligned with the can feeding chain plate, and the cans will enter the star tray can feeding trough. The eight stations feed cans continuously and uninterruptedly. The cans entering the star tray from the can feeding chain plate are brought to the second station with the star tray, and the unloading funnel is inserted into the can mouth. The funnel rotates with the can and completes the filling of materials at the third station. Auxiliary functions can be added to the fourth to sixth stations. Before the can is transferred to the seventh station, the funnel rises with the track and leaves the can mouth. When the can pauses at the seventh station, the can stops on the output chain plate, and the output chain plate carries the can filled with materials The cans are pulled out of the star disk slot to complete the output. The rotation of the star disk is controlled by a servo motor. The servo motor has a stable speed and stops accurately, which is more accurate than ordinary motors. The star disk pause speed can be set arbitrarily according to the can feeding speed. There are many combination methods. For example, if the can feeding speed is slowed down, the intermediate transition operation speed can be accelerated to maximize the total production speed. If I unload a lot of materials, it takes enough time. Similarly, I can compensate for the time spent on the pause by accelerating the intermediate transition operation. The total production speed is also maximized. It is easy to adjust. Once adjusted, it can be called directly later. The entire transmission structure is stable and runs smoothly. Since the funnel mouth is inserted into the can mouth when unloading, the material will not be spilled outside when filling, and the packaging and filling accuracy is guaranteed without polluting the equipment.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a servo-driven eight-station canning and packaging machine includes a main frame 2, with a stainless steel upper frame 1 mounted on top. The four corner columns of the stainless steel upper frame 1 are bolted to the four corners of the main frame 2. The stainless steel upper frame 1 is a welded body, with the four corner columns having flat edges at the outer corners, forming an isosceles trapezoid when viewed from above. Stainless steel corner guards 1-2 are mounted on the four legs of the main frame 2. Their corner shape matches the shape of the four corner columns of the stainless steel upper frame and are bolted to the four legs of the main frame 2. Guard plates 1-1 are installed on all four sides of the main frame between the stainless steel corner guards 1-2 and the corner guards.

[0029] Example 2

[0030] like Figure 5 、 Figure 6As shown, a main transmission mechanism A is installed at the center of the main frame 2 table. The main transmission mechanism A includes a supporting main cylinder 50-1. The base flange of the main cylinder 50-1 is fixedly connected to the main frame 2 by bolts. A transmission shaft 50-2 is passed through the center of the inner hole of the main cylinder 50-1. A deep groove ball bearing 1 50-5 is installed at the bottom end of the transmission shaft 50-2 and the bottom end of the main cylinder 50-1 hole, and a deep groove ball bearing 2 50-4 is installed at the top thereof. In this way, the transmission shaft 50-2 can rotate freely in the center of the main cylinder 50-1 hole. Since the equipment main disk is installed at the top of the transmission shaft 50-2, it must withstand downward pressure. A thrust bearing 50-3 is provided at the installation position of the top of the transmission shaft 50-2 and the main cylinder 50-1 to play a lifting role. In this way, the transmission shaft 50-2 can withstand radial force and axial force. A connecting flange 106 is mounted on the bottom end of the transmission shaft 50-2. This half-jointed flange 106 is bolted to the transmission shaft 50-2. A flat key is installed between the transmission shaft 50-2 and connecting flange 106 to prevent axial displacement of connecting flange 106. The top of connecting flange 106 contacts the bottom surface of the main barrel deep groove ball bearing 50-5, also providing a limiter. A matching connecting flange 2 105 is mounted on the bottom end of connecting flange 106. The inner hole of the top surface of connecting flange 2 105 penetrates the bottom end of the transmission shaft 50-2 and is bolted to the bottom end surface of connecting flange 106. Due to the transition fit between the inner hole of the top surface of connecting flange 2 105 and the transmission shaft 50-2, excellent coaxiality is ensured. The bottom section of the second connecting flange 105 is bolted to the rotor of the harmonic reducer 103. The harmonic reducer 103 body is mounted on the bottom surface of the main cylinder 50-1 via a support base 104. The servo motor 100 drive shaft is located within the mounting hole of the harmonic reducer 103 rotor and secured via a fastening sleeve 102, creating a bolted, tightly packed structure. The servo motor 100 body is mounted on the bottom end surface of the harmonic reducer 103 body support base 104 via a column 101. This ultimately enables the servo motor 100 to drive the drive shaft 50-2 through the harmonic reducer 103.

[0031] Example 3

[0032] like Figure 7As shown, the main transmission mechanism A also includes a circumferential track 150 fixed to the top flange of the main cylinder 50-1. The track 150 has a high-point operation, a low-point operation and a transition. The low point controls the funnel to be inserted into the tank mouth, and the high point controls the funnel to be lifted out of the tank mouth. It includes a star disk fixing seat 211 installed on the bottom flange of the transmission shaft 50-2. The star disk fixing seat 211 has eight blanking column 60 mounting holes evenly distributed along the circumference. The outer circle of the star disk fixing seat 211 is machined with positioning steps to ensure that the star disk 200 is concentric with the star disk fixing seat 211 after installation. The main transmission mechanism A also includes a blanking column fixing plate 210 fixed to the top flange of the transmission shaft 50-2. The fixing plate 210 has eight blanking column 60 positioning holes evenly distributed along the circumference. After installation, the eight blanking column 60 mounting holes on the star disk fixing seat 211 are concentric with the eight positioning holes on the fixing plate 210.

[0033] There are eight blanking columns 60 installed on the star disk fixing seat 211. The blanking columns 60 include a support column 60-1, and a lifting shaft 60-3 is passed through the support column 60-1. A linear bearing 60-10 is installed at the upper and lower ends of the inner hole of the support column 60-1, which plays the role of positioning the lifting shaft 60-3. A dust cover 60-2 is installed on the top of the support column 60-1. The inner hole of the dust cover 60-2 is fixed on the lifting shaft 60-3 and moves up and down with the lifting shaft 60-3. A pair of symmetrical positioning slots are processed in the middle and lower position of the support column 60-1. The positioning block 60-4 passes through the slot on the support column 60-1 and is installed on the lifting shaft 60-3 to play a limiting role and prevent the lifting shaft 60-3 from rotating. A rolling bearing 60-6 is installed at the bottom end of the lifting shaft 60-3. The rolling bearing 60-6 is installed on the lifting shaft 60-3 through the bearing shaft 60-5;

[0034] like Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown, the rolling bearing 60-6 of the lifting shaft 60-3 is in contact with the upper end surface of the track 150, the support column 60-1 is mounted on the star disk fixing seat 211, and the star disk fixing seat 211 is mounted on the transmission shaft 50-2. In this way, the rotation of the transmission shaft 50-2 will drive the star disk fixing seat 211 to rotate, thereby rotating the blanking column 60 fixed thereon, and the lifting shaft 60-3 of the blanking column 60 will move up and down with the height of the track 150. The track 150 is fixed on the main cylinder 50-1 and does not move. A funnel fixing arm 11 is installed on the top of the blanking column 60. The fixing arm 11 is clamped on the lifting shaft 60-3 by bolts. The height position can be adjusted on the lifting shaft 60-3 by loosening the bolts. A blanking funnel 10 is installed outwardly of the fixed arm 11. Since the fixed arm 11 can be adjusted in height along the lifting shaft 60-3, the height of the blanking funnel 10 can be arbitrarily adjusted according to different tank heights. Finally, the lifting and lowering of the blanking funnel 10 is realized, and the track 150 is used to insert the blanking funnel into the tank opening and to raise the blanking funnel to remove the blanking funnel;

[0035] like Figure 12 As shown, a star plate 200 is installed on the star plate fixing seat 211. The outer circle of the star plate 200 is evenly distributed with eight can feeding slots according to different can types. After the packaged cans enter the can feeding slots of the star plate 200, the loading cans will be brought to the next station as the star plate 200 rotates. Its function is to realize the loading of packaged cans into the cans, and the star plate 200 drives the packaged cans to the unloading station to complete the filling, and then brings the cans filled with materials to the output station as it rotates;

[0036] The can inlet conveying chain plate E and the can outlet conveying chain plate F are installed at a 90-degree angle. A can supporting plate B is installed on the table of the main frame 2. The can supporting plate B is installed in a ring shape, supporting the can from the can inlet conveying chain plate E to the can outlet conveying chain plate F. An outer guardrail 201 is installed on the top surface of the outer edge of the can supporting plate F to ensure that the cans are loaded against the can inlet slot of the star plate 200 and rotate with the star plate 200.

[0037] Working principle: First, the star disk 200 operates in an intermittent pause mode, rotating one station 45 degrees each time. Since the star disk 200 has 8 evenly distributed slots for the can feed slot, each time it rotates one station, the slots on the star disk 200 will be aligned with the can feed chain plate E, and the canned packages will enter the star disk can feed slot. The eight stations feed cans continuously and uninterruptedly. The star disk cans entering from the can feed chain plate E are brought to the second station by the star disk 200, and the unloading funnel 10 is inserted into the can mouth. The funnel 10 rotates with the can and completes the filling of materials at the third station. Auxiliary functions can be added to the fourth to sixth stations. Before the can is transferred to the seventh station, the funnel 10 rises with the track and leaves the can mouth. When the can pauses at the seventh station, the can stops on the output chain plate F, and the output chain plate F pulls the can filled with materials out of the star disk 200 slot to complete the output. The rotation of the star disk 200 is controlled by a servo motor 100. This motor offers stable speed, precise stopping, and higher precision than conventional motors. Furthermore, the pause speed of the star disk 200 can be arbitrarily set based on the tank feed rate, allowing for multiple combinations. For example, if the tank feed rate is slowed, the intermediate transition speed can be accelerated, ultimately maximizing overall production speed. For example, if I'm unloading a large amount of material, which requires ample time, I can compensate for the pause time by accelerating the intermediate transition speed, thus maximizing overall production speed. Adjustment is also easy; once adjusted, it can be reused later. The entire transmission structure is stable and operates smoothly. Because the hopper is inserted into the tank opening during unloading, material is prevented from spilling during filling, ensuring precise packaging and filling without contaminating the equipment.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
