[0022] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please see Figure 1-6 As shown, the counting and packaging equipment of the present invention is used to count parts and package the counted components. It includes a frame and a counting device 01 and a packaging device 02 mounted within the frame. The counting device 01 is located directly below the packaging device 02. As parts pass through the counting device 01, the counting device 01 counts the passing parts. When a predetermined number of parts is reached, the parts move into the packaging device 02 for packaging. This ensures that the number of parts packaged each time is the same.

[0024] Please see Figure 2As shown, the counting device 01 includes a feeding hopper 03 fixedly installed on the frame and two feeding troughs 04. One end of the feeding trough 04 is connected to the feeding hopper 03, and the other end is connected to the receiving hopper 05. A visual counting component 06 for counting parts is provided between the feeding trough 04 and the receiving hopper 05. The visual counting component 06 is an externally purchased industrial camera. Two feeding troughs 04 are fixedly mounted on the frame via linear vibrators 07. One feeding trough 04 is wider than the other. During operation, one feeding trough 04 feeds parts into the receiving hopper 05. Feeding stops when the count by the visual counting unit 06 reaches a set value, and the other feeding trough 04 starts, feeding the remaining parts into the receiving hopper 05. For example, if one thousand parts need to be fed into the receiving hopper 05, one feeding trough 04 starts, and when the number of parts passing through the visual counting unit 06 reaches nine hundred, feeding stops. The other feeding trough 04 starts, continuing to feed one hundred parts into the receiving hopper 05. The two feeding troughs 04 cumulatively feed one thousand parts into the receiving hopper. Because one feeding trough 04 is wider than the other, the wider trough 04 is used to feed nine hundred parts, increasing the feeding speed, while the narrower trough 04 is used to feed one hundred parts, improving quantity accuracy. The design of the feeding trough 04, with one wide and one narrow section, ensures accurate quantity feeding each time.

[0025] The bottom of the receiving hopper 05 is provided with a discharge port 08, and a baffle 09 is provided at the discharge port 08. The two ends of the baffle 09 are connected to the outer surface of the receiving hopper 05 through a cylinder 10. When the number of parts entering the discharge hopper reaches a certain amount, the cylinder 10 starts to work, removing the baffle 09 from the discharge port 08. The parts inside the receiving hopper 05 then fall out of the discharge port 08.

[0026] A temporary storage hopper 11 with the same structure is located directly below the receiving hopper 05. A feeding channel 12 for supplying materials to the packaging device is located directly below the temporary storage hopper 11, and a collection hopper 13 is located on one side of the feeding channel 12. Through the temporary storage hopper 11, after parts enter the receiving hopper 05, the two feeding troughs 04 continue to convey parts into the receiving hopper 05, while the parts in the temporary storage hopper 11 are promptly fed back after the packaging device finishes its work, thus achieving continuous packaging. This solves the problem of the packaging device or feeding trough 04 stopping and waiting. A lifting component is fixed on the frame, and the temporary storage hopper 11 is fixedly mounted on the lifting component. When the number of parts in the receiving hopper 05 is incorrect, the lifting component pushes the temporary storage hopper 11 to move, causing the temporary storage hopper 11 to be misaligned with the feeding channel 12. This further ensures the accuracy of the quantity.

[0027] The lifting component includes a lifting seat 14 fixedly mounted on the frame. A cylinder 10 is horizontally mounted on the lifting seat 14. A lifting plate 15 is fixedly mounted on the output end of the cylinder 10. Guide shafts 16 are fixedly mounted on both ends of the lifting plate 15, and the guide shafts 16 are slidably connected to the lifting seat 14 via support bearings. The aforementioned temporary storage hopper 11 is fixedly mounted on the lifting plate 15. When the output end of the cylinder 10 extends, the temporary storage hopper 11 is connected to the collection hopper 13. When the output end of the cylinder 10 retracts, the temporary storage hopper 11 is connected to the feeding channel 12.

[0028] The packaging device 02 includes a packaging rack 17 installed within a frame, a fixing plate 18 fixedly mounted on the packaging rack 17, and a lifting device 19 disposed within the packaging rack 17. A feeding component 20 is fixedly mounted on the upper side of the fixing plate 18, and a pulling device 21 is slidably mounted on the lower side of the fixing plate 18. An auxiliary device 22 is provided on one side of the pulling device 21, and a unloading device 23 is provided directly below the feeding component 20.

[0029] The feeding component 20 includes a receiving rack 24 fixedly mounted above the fixed plate 18. A receiving hopper 25 is fixedly mounted on the receiving rack 24, and the receiving hopper 25 is connected to the aforementioned feeding channel 12. A sliding cylinder 26 is mounted on one side of the receiving hopper 25, and an extension tube 27 is fixedly mounted on the output end of the sliding cylinder 26, which is sleeved below the receiving hopper 25. During the feeding process, when the output end of the sliding cylinder 26 extends, it connects the packaging strap and the receiving hopper 25.

[0030] Please see Figure 3 As shown, the pulling device 21 includes a pulling plate 28 slidably mounted on the bottom surface of a fixed plate 18 via a sliding guide rail. A pen-shaped cylinder is fixedly mounted on the fixed plate 18 to drive the pulling plate 28 to reciprocate between the feeding component 20 and the lifting device 19 along the sliding guide rail. A through groove is provided in the middle of the pulling plate 28, and clamping plates 29 are slidably connected to both sides of the through groove. A cylinder is fixedly mounted on the pulling plate 28 to drive the clamping plates 29 to move on the pulling plate 28. A front plate 30 is fixedly mounted in the middle of the clamping plates 29, and an upper sealing strip 31 for sealing the packaging bag is designed directly below the front plate 30. A cylinder 10 is fixedly mounted on the clamping plates 29, and a rear plate 32 located directly in front of the front plate 30 is fixedly mounted on the output end of the cylinder.

[0031] In use, the packaging bag is placed between the front plate 30 and the rear plate 32. The output end of the cylinder mounted on the clamping plate 29 retracts, driving the rear plate 32 to move towards the front plate 30, thereby securing the packaging bag. Simultaneously, the output end of the cylinder mounted on the pull plate 28 retracts, driving the clamping plate 29 to move to both sides of the through slot, thereby opening the packaging bag. Subsequently, the extension tube 27 on the feeding component 20 moves downward and extends into the packaging bag. After all the components have entered the packaging bag through the receiving hopper 25, the output end of the cylinder mounted on the pull plate 28 extends, and then the electrically heated sealing strip is activated to seal the opening of the packaging bag.

[0032] Please see Figure 4 As shown, the auxiliary device 22 includes an auxiliary frame 33 fixedly mounted on a fixed plate 18. Two connecting seats 34 are slidably mounted on the bottom of the auxiliary frame 33 via a sliding guide rail. A drive shaft 35 is provided on one side of the auxiliary frame 33, with drive threads in opposite directions on the drive shaft 35. Each of the two connecting seats 34 is equipped with a drive rod adapted to the drive thread. When the drive shaft 35 rotates, the two connecting seats 34 are driven to move on the auxiliary frame 33 via the drive threads in opposite directions on the drive shaft 35. A slide cylinder 26 is mounted on each connecting seat 34. An auxiliary strip 36 is fixedly mounted on the output end of the slide cylinder 26, and a finger cylinder 37 is fixedly mounted on the auxiliary strip 36. An auxiliary plate is fixedly mounted on the output end of the finger cylinder 37. Before the sealing strip seals the packaging bag, the auxiliary plate clamps and straightens both sides of the packaging bag, facilitating the sealing strip's sealing of the packaging bag.

[0033] Please see Figure 5 As shown, the unloading device 23 includes a bracket 38 fixedly installed within the packaging frame 17. A horizontal plate 39 is slidably mounted vertically within the bracket 38. The horizontal plate 39 and the bracket 38 are connected by a sliding guide rail, and the horizontal plate 39 is driven to move up and down by a lead screw and a servo motor. A V-shaped unloading plate 40 is rotatably mounted below the horizontal plate 39 via a bearing. The bottom of the unloading plate 40 is fixedly connected to the horizontal plate 39 by a cylinder. When the output end of the cylinder extends, the unloading plate 40 is in a horizontal state. When the packaging bag contains parts, the unloading plate 40 lifts the packaging bag. After the packaging bag is sealed, the output end of the cylinder retracts, and the unloading plate 40 rotates to an inclined state. The packaging bag containing parts falls down.

[0034] Please see Figure 6As shown, the lifting device 19 includes a lifting frame fixedly installed within the packaging rack 17. A lifting plate 41 is slidably mounted vertically within the lifting frame, and the lifting plate 41 is connected to the lifting frame via a sliding guide rail. A drive screw is rotatably mounted on one side of the lifting plate 41 via a bearing. A nut adapted to the drive screw is mounted on the lifting plate 41. A servo motor that drives the drive screw to rotate is mounted at the bottom of the rack. During the rotation of the drive screw, the lifting plate 41 moves vertically through the cooperation of the drive screw and the nut. The lifting plate 41 has a square hole, and a sealing plate 42 and a clamping plate are slidably mounted on both sides of the square hole. The sealing plate 42 is located directly below the clamping plate. The sealing plate 42 and the clamping plate are slidably connected to the lifting plate 41 via the sliding guide rail. A groove is provided between the sealing plate 42 and the clamping plate, and a cutting blade 44 is installed in the groove. A cylinder that drives the cutting blade 44 to move is fixedly mounted on the clamping plate. The lifting plate 41 is fixedly equipped with cylinders that drive the clamping plate and sealing plate 42 to move respectively. The clamping plate is provided with a lower sealing strip 43 for electrically heating and sealing the packaging bag.

[0035] In use, the clamping plate 45, lower sealing strip 43, and cutting blade 44 are in the open state. The packaging bag is placed between the clamping plates 45, which then close to clamp the bag. A servo motor drives the lifting plate 41 to the top of the lifting frame. The bag is then gripped by the aforementioned pulling device 21. The clamping plate 45 reopens. The servo motor drives the lifting plate 41 to move downwards. After reaching the set position, the clamping plate and lower sealing strip 43 close, and the lower sealing strip 43 activates to seal the bag. Once sealed, the cutting blade 44 closes to cut the bag. The process is then repeated to produce the next packaging bag.

[0036] It should be noted that the opening and closing of the fixing plate 18, the lower sealing strip 43, and the cutting blade 44 are all achieved by the extension and retraction of the corresponding cylinder output ends.

[0037] It should be noted that, for clarity, the fasteners described in this application are any one of screws, bolts, and bolts. Different types of "cylinders" installed in different positions are identified by the same reference numeral "10". Different types of "slide cylinders" installed in different positions are identified by the same reference numeral "26".

[0038] If the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
