[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0034] See also Figure 1-2 The present invention provides a technical solution: a new sleeve-type packaging machine, which uses a product conveyor belt to convey a plurality of products to be packaged, including a frame 1, a peeling mechanism 2, a material receiving mechanism 3, a material feeding mechanism 4, a cutting mechanism 5, a film collecting mechanism 6, a film releasing mechanism 7, a material pressing mechanism 8 and a material discharge port 9;

[0035] Specifically: the peeling mechanism 2 is located in the product loading area and is connected to the conveying end of the product conveyor belt. It is used for peeling between the products to be packaged. The feeding mechanism 3 is used to sense whether the product is in place. The feeding mechanism 4 is superimposed on the upper part of the feeding mechanism 3 to push the product toward the discharge port 9 where the packaging film is located. The cutter mechanism 5 is located inside the discharge port 9 and is used to cut the packaging film after the product is coated. The pressing mechanism 8 is located at the rear of the discharge port 9 and is used to press down and constrain the product during the packaging film cutting process. There are two groups of film releasing mechanisms 7, and the two groups of film releasing mechanisms 7 are respectively located at the top and bottom of the frame 1 to release the packaging film. There are two groups of film collecting mechanisms 6, corresponding to the positions of the film releasing mechanisms 7, for connecting the packaging film released by the transition film releasing mechanism 7.

[0036] When the new cuff-type packaging machine is working, several tape products are conveyed one by one to the stripping mechanism 2 through an external product conveyor belt, and then conveyed to the feeding mechanism 3. After the feeding mechanism 3 detects that the tape products are in place, the feeding mechanism 4 pushes the tape products toward the discharge port 9 (for example, the feeding mechanism 4 can only push 5 tape products at a time, so the 6th and subsequent tape products are clamped by the stripping mechanism 2. When the feeding mechanism 4 pushes 5 tape products, the 5th tape product will be peeled off from the 6th tape product). At the same time, the two sets of film-releasing mechanisms 7 release the packaging film, and after passing through the film-receiving mechanism 6, it enters the discharge port 9. When the product is pushed over, the packaging film at the discharge port 9 just wraps the product, and then the pressing mechanism 8 presses down and fixes the product, and the cutting mechanism 5 cuts the packaging film.

[0037] See also Figure 3 The stripping mechanism 2 includes a stripping support 23 fixedly mounted on the outside of the frame 1, and the bottom end of the stripping support 23 is threadedly connected to a stripping screw pair 25, and the driven end of the stripping screw pair 25 is fixedly connected to the driving end of the first DC motor 21 through a first coupling 22. The two sides of the bottom end of the stripping support 23 are connected with stripping slide rails 24, and the stripping support 23 slides on the bottom plate through the stripping slide rails 24. The end of the bottom plate is connected to a first width adjustment plate 26 for clamping the product, and the end of the first width adjustment plate 26 is connected to a product guide plate 27. The stripping mechanism 2 also includes a stripping mounting base plate 202 fixedly mounted on the outside of the frame 1, and a stripping cylinder 201 and a stripping guide rod 29 are provided at the top of the stripping mounting base plate 202. The stripping guide rod 29 is movably connected to the stripping mounting base plate 202, and the telescopic end of the stripping cylinder 210 and the end of the stripping guide rod 29 are jointly connected to a second width adjustment plate 28 for clamping the product.

[0038] When the stripping mechanism 2 is working, the tape product passes between the first width adjustment plate 26 and the second width adjustment plate 28, and the stripping support 23 is fixed. Then, when the first DC motor 21 drives the stripping screw pair 25 to rotate, the base plate connected to the first width adjustment plate 26 moves under the reaction force, thereby driving the first width adjustment plate 26 to move. During the movement, the stripping cylinder 201 pushes the second width adjustment plate 28 close to the first width adjustment plate 26. According to the actual width of the tape product, the first width adjustment plate 26 and the second width adjustment plate 28 can be adjusted, and finally the tape product is clamped and fixed.

[0039] See also Figure 4 The feeding mechanism 3 includes a feeding mounting base plate 33 installed on the top of the frame 1, a second DC motor 31 is installed on the end of the feeding mounting base plate 33, and the feeding screw pair 39 is rotatably connected inside the feeding mounting base plate 33, and the driving end of the second DC motor 31 is connected to the feeding screw pair 39 through a second coupling 32, and the upper part of the feeding mounting base plate 33 is slidably connected to the slide mounting plate 34 through the feeding slide rail 38, and the top of the slide mounting plate 34 is connected to the feeding sensor support 36, and the feeding sensor 35 is installed inside the feeding sensor support 36, and the inside of the feeding sensor support 36 is located on both sides of the feeding sensor 35 and is slidably connected with the sensing guide rod 37 (the outside of the sensing guide rod 37 is covered with a spring), and the end of the sensing guide rod 37 is connected to the feeding baffle mounting block 302, and the end face of the feeding baffle mounting block 302 is connected to the feeding baffle 301 for contacting the product.

[0040] When the material arrival mechanism 3 is working, after the tape products pass through the stripping mechanism 2, under the pushing action, several tape products at the starting end will be pushed to the position of the material arrival baffle 301 and abut against the material arrival baffle 301, and a force will be applied to the material arrival baffle 301. After being subjected to the force, the material arrival baffle 301 will move toward the direction of the material arrival sensor 35 until it contacts the material arrival sensor 35. After contact, it indicates that the tape products are in place. According to the packaging specifications, the material arrival baffle 301 can also be adjusted. For example, when 5 tape products are selected as a group, the position of the material arrival baffle 301 can be the same as shown in the figure. If 3 tape products are selected as a group (the overall packaging length is reduced), the second DC motor 31 drives the material screw pair 39 to rotate, and then drives the slide mounting plate 34 to move, so that the initial position of the material arrival baffle 301 can be adjusted.

[0041] See also Figure 5The feeding mechanism 4 includes a feeding support 42 and a feeding base connecting plate 49 installed at the top of the frame 1. The top of the feeding base connecting plate 49 is connected to the feeding cylinder base 47, and the inner side of the feeding support 42 is connected to the feeding cylinder mounting plate 48. The end faces of the feeding cylinder base 47 and the feeding cylinder mounting plate 48 are jointly installed with the feeding cylinder 46. The inside of the feeding cylinder mounting plate 48 and the two sides of the feeding cylinder 46 are connected with the feeding bearing 45. The inside of the feeding bearing 45 is slidably connected with the feeding guide rod 44. The telescopic end of the feeding cylinder 46 and the end of the feeding guide rod 44 are jointly connected with the feeding push plate 43, and the end of the feeding push plate 43 is connected with the feeding baffle 41.

[0042] When the feeding mechanism 4 is working, after detecting that the tape products are in place, the feeding cylinder 46 pushes the feeding push plate 43 to move, and the feeding push plate 43 pushes several tape products in place to move synchronously toward the discharge port 9.

[0043] See also Figure 6 The cutter mechanism 5 includes a cutter cylinder mounting plate 52 mounted on the upper part of the frame 1 and a lower knife seat mounting plate 59 mounted on the lower part of the frame 1. A cutter cylinder 51 is mounted on the upper part of the cutter cylinder mounting plate 52, and a lower knife seat 57 is mounted on the upper part of the lower knife seat mounting plate 59. A high-temperature resistant silicone strip 58 is mounted on the top of the lower knife seat 57. A cutter guide shaft 53 is commonly connected between the cutter cylinder mounting plate 52 and the lower knife seat mounting plate 59. The outer part of the cutter guide shaft 53 is slidably connected to a cutter guide support 54. The end face of the cutter guide support 54 is connected to a bakelite connecting block 55. A cutter 56 is commonly connected between the two cutter guide supports 54. The telescopic end of the cutter cylinder 51 is fixedly connected to the cutter 56.

[0044] When the cutter mechanism 5 is working, the cutter cylinder 51 extends, pushing the cutter 56 downward. During the downward movement, the blade of the cutter 56 contacts the packaging film. When the cutter 56 abuts against the high-temperature resistant silicone strip 58, the packaging film is cut.

[0045] See also Figure 7 The film collecting mechanism 6 includes a film collecting support 61 installed at the bottom of the frame 1, and the film collecting supports 61 are commonly connected with a film collecting guide rod 62, and the outside of the film collecting guide rod 62 is slidably connected with a film collecting guide block 63, and a buffer spring 64 is connected between the film collecting support 61 and the film collecting guide block 63. A film collecting roller 66 is commonly connected between the two film collecting guide blocks 63, and the outside of the film collecting roller 66 is rotatably connected with a film collecting guide ring 67, and an induction sheet 65 is installed on the outside of one of the film collecting guide blocks 63.

[0046] When the film collecting mechanism 6 is working, the packaging film passes under the film collecting roller 66, and cooperates with the rotating film collecting guide ring 67 to reduce the resistance of the packaging film during movement. In addition, the sensor sheet 65 can also sense the tension of the packaging film.

[0047] See also Figure 8 The film unloading mechanism 7 includes a film unloading chain roller 71 rotatably connected to the inner wall of the frame 1, and film blocking rings 73 are installed at both ends of the film unloading chain roller 71, and film blocking rings 72 are installed on the outside of the film blocking rings 73 at both ends of the film unloading chain roller 71. The driven end of the film unloading chain roller 71 is connected to the driving end of the film unloading motor 74, and a film unloading protective cover 75 is installed at the connection between the film unloading chain roller 71 and the film unloading motor 74.

[0048] When the film releasing mechanism 7 is working, the film releasing motor 74 drives the film releasing chain roller 71 to rotate, and the packaging film can be released. During the releasing process, the film blocking ring 73 can prevent the packaging film from being released and deviating, and limit it. The film blocking ring 72 and the film blocking ring 73 are an integrated structure, and the film blocking ring 72 is equivalent to a nut. Threads are provided at both ends of the film releasing chain roller 71, and the film blocking ring 72 and the film blocking ring 73 are fixed to the film releasing chain roller 71 through the threads.

[0049] See also Figure 9 The pressing mechanism 8 includes a symmetrically arranged pressing mounting base plate 84, the top of the pressing mounting base plate 84 is rotatably connected to a pressing adjusting rod 83, and the inner side of the pressing mounting base plate 84 is rotatably connected to a driven shaft, the pressing adjusting rod 83 and the driven shaft are connected through a bevel gear set 82, the external thread of the driven shaft is connected to a pressing screw pair 85, the end of the pressing adjusting rod 83 is installed with a pressing handwheel 81, the two pressing screw pairs 85 are jointly installed with a pressing cylinder mounting plate 86, the pressing cylinder A pressing support plate 801 is installed at the front end of the mounting plate 86, and the bottom end of the pressing support plate 801 is connected to the cylinder locking plate 802. A pressing cylinder 88 is installed on the top of the cylinder locking plate 802, and the telescopic end of the pressing cylinder 88 is connected to the pressing connecting block 803. A slider bearing 87 is installed on the back side of the pressing cylinder mounting plate 86, and the internal sliding connection of the slider bearing 87 is connected to the pressing guide rod 89. The bottom ends of the pressing connecting block 803 and the pressing guide rod 89 are commonly connected to the pressing plate 804.

[0050] When the pressing mechanism 8 is working, the initial height of the pressing plate 804 can be adjusted by rotating the pressing handwheel 81. When the pressing handwheel 81 is rotated, the pressing adjustment rod 83 is driven to rotate. Under the action of the bevel gear set 82, the driven shaft rotates. Since the driven shaft and the pressing screw pair 85 are threadedly connected, the pressing screw pair 85 moves up and down, which can change the initial height of the pressing plate 804. When the product needs to be pressed down and fixed, the pressing cylinder 88 extends to drive the pressing plate 804 to move down until it contacts the upper surface of the product.

[0051] During use, multiple rolls of adhesive tape are delivered to the main machine's feeding mechanism 3 through a conveyor line (not shown in the figure). The feeding baffle 301 on the feeding mechanism 3 is subjected to pressure, causing the feeding baffle mounting block 302 connected to the feeding baffle 301 to retreat. The feeding baffle mounting block 302 is close to the feeding sensor 35, and the stripping mechanism 2 is activated to press the tape. The feeding push plate 43 of the feeding mechanism 4 pushes the tape to the film and reaches the discharging mechanism 9. The pressing mechanism 8 is activated to limit the tape's retreat through the pressing plate 804. The cutter mechanism 5 is activated to cut the film. The pressing mechanism 8 and the stripping mechanism 2 are reset to complete the packaging. The feeding mechanism 3 and the stripping mechanism 2 are electrically adjusted, making it easier to debug the machine. The pure steel material is not easily worn. The feeding mechanism 3 and the feeding mechanism 4 are staggered, which can achieve universal tape sizes and one machine for packaging single to multiple rolls of tape, greatly reducing the packaging cost of the tape industry.
