Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to a powder roll packaging machine. Background Technology

[0002] A granular packaging machine is a specialized device for the automatic, quantitative packaging of granular materials. It is widely used in the food, pharmaceutical, and chemical industries, and is suitable for packaging granular or small-lump products such as pharmaceutical granules and fertilizers. Typically, the feeding system supplies the granular material to the packaging machine, and a metering mechanism precisely controls the amount of material packaged each time. If roll film is used, this device forms the bag shape, and then seals the bag containing the material. For continuous packaging, the bag needs to be cut and separated after each packaging step. Currently, the sealing mechanism of this type of packaging machine is usually fixedly installed on the machine frame. A roller-type pull-down mechanism is set below the heat sealing mechanism to pull the packaging bag downwards. The pull-down and heat sealing actions are alternated to achieve continuous heat sealing packaging. This method requires high precision in the coordination between the pull-down mechanism and the hot air mechanism. In addition, the existing packaging machines are usually suitable for packaging granular materials of various sizes. When changing the packaging size of the product, the height and tilt angle of the conical hopper need to be adjusted to match the inlet of the packaging bag. However, the conical hopper and the machine frame are usually connected by bolts and flange plates, which does not allow for precise adjustment of angle and height and makes the operation relatively cumbersome.

[0029] Example 1, see appendix Figure 1-39-11, A powder roll film packaging machine, the packaging machine includes a conical hopper, a film feeding bracket 05, a dual-station heat sealing device 01, and a bag cutting device 02 installed on a frame 07. The conical hopper is set at the upper end of the frame 07 by a bidirectional support 04. The film feeding bracket 05 is set on one side of the conical hopper. The film roll of the packaging bag is installed on the film feeding bracket 05. The packaging film is automatically fed offline by the film feeding bracket 05. The dual-station heat sealing device 01 is installed in the middle of the frame 07. The bag cutting device 02 is set below the dual-station heat sealing device 01. A back sealing device 03 is provided above the dual-station heat sealing device 01. The back sealing device 03 seals the back of the strip-shaped packaging film. Then, the dual-station heat sealing device 01 seals the bottom and end of the packaging film. The dual-station heat sealing device 01 includes a rocker arm drive mechanism 1 and a heat sealing mechanism 2 mounted on a frame 07. Two vertical guide rails 31 are symmetrically arranged on both sides inside the frame 07. The two sides of the heat sealing mechanism 2 are connected to the two guide rails 31 through sliders 21. The heat sealing mechanism 2 can slide along the guide rails 31 through the sliders 21. The rocker arm drive mechanism 1 includes a motor 11, a rocker arm 12 and a connecting rod 13. A motor support 111 is provided at the bottom of the frame 07. The motor 11 is installed in the motor support 111.

The lower end of the connecting rod 13 is hinged to the upper end of the rocker arm 12, and the upper end of the connecting rod 13 is hinged to the middle of the heat sealing mechanism 2. The rocker arm drive mechanism 1 drives the rocker arm 12 to rotate via the motor 11. When the rocker arm 12 rotates to the upper part, it pushes the heat sealing mechanism 2 upward via the connecting rod 13, causing it to slide upward along the guide rail 31. When the rocker arm 12 rotates to the lower part, it pulls the heat sealing mechanism 2 downward via the connecting rod 13, causing it to slide downward along the guide rail 31.

[0030] The upper end of the main rod of the connecting rod 13 is connected to the upper bearing seat 131. The middle part of the heat sealing mechanism 2 is connected to the upper bearing seat 131 through a short shaft, and the lower end is connected to the lower bearing seat 132. The upper end of the rocker arm 12 is connected to the lower bearing seat 132 through a short shaft. Both ends of the main rod of the connecting rod 13 are provided with threaded shafts, and the threaded shafts at both ends are threadedly connected to the two bearing seats respectively. The main rod can be rotated to adjust the connection length of the bearing seats through the threads, thereby adjusting the length of the main rod, which is beneficial for assembly and subsequent debugging and maintenance operations.

[0031] The main body 32 of the heat sealing mechanism 2 is slidably connected to both ends of guide posts 33. A sliding seat 22 is connected between the middle of the two guide posts 33 on one side of the main body 32. The sliding seat 22 can slide freely back and forth along the two guide posts 33. An inner heating block 221 is provided on the inner side of the sliding seat 22. A movable seat 23 is fixedly connected between the ends of the two guide posts 33 on the outer side of the sliding seat 22. The movable seat 23 can slide along the main body 32 integrally with the guide posts 33. An outer heating block 231 is provided on the side of the movable seat 23, which is directly opposite the inner heating block 221. The outer heating block 231 and The inner heating blocks 221 move towards each other and come into contact to achieve heat sealing of the packaging bag; the main body 32 is provided with cylinder A 24 and cylinder B 25 in the middle. The piston rod A 241 of cylinder A 24 is connected to the middle of the sliding seat 22. Cylinder A 24 pushes and pulls the sliding seat 22 and the heating blocks to slide along the guide post 33. A connecting plate 26 is provided between the outer ends of the two guide posts 33 on the other side of the main body 32. The piston rod B 251 of cylinder B 25 is connected to the middle of the connecting plate 26. Cylinder B 25 pushes and pulls the connecting plate 26 and the guide post 33 to slide along the main body 32.

[0032] A U-shaped auxiliary bracket 27 is provided between the two ends of the main body 32. The piston rod 251 passes through the through hole in the middle of the U-shaped auxiliary bracket 27, and the guide post 33 slides through the end of the U-shaped auxiliary bracket 27. The U-shaped auxiliary bracket 27 provides auxiliary support for the guide post 33 and improves the sliding stability of the guide post 33.

[0033] The bottom surface of the inner heating block 221 is provided with an inner exhaust pressure plate 28, and the bottom surface of the outer heating block 231 is provided with an outer exhaust pressure plate 29. During the closing process of the inner heating block 221 and the outer heating block 231, the two exhaust pressure plates can press the packaging bag from both sides to expel the air inside the packaging bag and improve the packaging quality.

[0034] When the rocker arm type 12 dual-station packaging bag heat sealing device of this embodiment is working, the rocker arm drive mechanism 1 drives the heat sealing mechanism 2 to move up and down reciprocally. After the heat sealing mechanism 2 heat seals the bottom of the packaging bag, it keeps the bag in a clamped state and pulls the packaging bag downward. When the upper end of the packaging bag moves to the heat sealing position, the heat sealing mechanism 2 releases the packaging bag and moves upward to the heat sealing position to heat seal the bag opening. The reciprocating movement of the heat sealing mechanism 2 realizes the continuous heat sealing packaging operation of the packaging bag. When the heat sealing mechanism 2 is working, cylinder A 24 and cylinder B 25 are started simultaneously. Cylinder A 24 drives the sliding seat 22 and the inner heating block 221 to slide outward along the two guide posts 33. Cylinder B 25 drives the guide post 33 to slide along the main body 32 through the connecting plate 26. The moving seat 23 at the end of the guide post 33 and the outer heating block 231 slide inward. The two heating blocks slide towards each other and contact each other to realize the heat sealing of the packaging bag.

The reinforcing plate has a threaded hole in the middle, and an auxiliary bolt 46 is connected in the threaded hole. The inner end of the auxiliary bolt 46 is pressed against the lower surface of the support plate 42. The auxiliary bolt 46 supports the support plate 42 and provides support force for the conical storage hopper 06. The auxiliary bolt 46 also assists the support rod 43 in supporting the conical storage hopper 06, ensuring the stability of the conical storage hopper 06.

[0037] The lifting and adjusting mechanism includes a rotating support 411, a lead screw 412, and a nut sleeve 413 disposed at the lower part of the support plate 42. A lifting plate 414 is fixedly disposed at the upper part of the conical storage hopper 06. The nut sleeve 413 is disposed at the lower part of the lifting plate 414.

The support rod 43 remains connected between the two. After the angle of the conical storage hopper 06 is adjusted to the correct position, the locking screw 45 is turned to tighten and lock the support rod 43. The support rod 43 is then fixedly supported on the adjusting support 4 and the conical storage hopper 06. Between, then tighten the auxiliary bolt 46 so that its end abuts against the surface of the support plate 42, providing auxiliary support force for the conical storage hopper 06 and ensuring the assembly stability of the conical storage hopper 06; when the lifting mechanism of this embodiment is in use, rotate the handwheel 425 to drive the horizontal shaft 423 and the active bevel gear 424 to rotate, the active bevel gear 424 drives the driven bevel gear 421 and the lead screw 412 to rotate, and the lead screw 412 drives the nut sleeve 413 through the thread to raise or lower the lifting plate 414, thereby realizing the height adjustment of the conical storage hopper 06.
