Description

Technical Field

[0001] This utility model relates to the technical field of medical dressing filler devices, and in particular to an automatic feeding mechanism for marker pens in a three-dimensional packaging machine. Background Technology

[0002] In the medical device manufacturing industry, 3D packaging machines are core equipment for the post-packaging of consumables such as medical markers. As specialized instruments used for surgical marking and other scenarios, medical markers must meet stringent requirements for sterility and precision. The efficiency, cleanliness, and automation level of the packaging process directly determine product quality and production line compliance.

[0003] Currently, most companies still use manual or semi-automated material handling. Manual handling requires workers to wear gloves and protective clothing in a cleanroom and operate according to aseptic procedures. This involves placing each pen individually and accurately counting them to match the fixed quantity requirements for each package. Semi-automation relies on a vibratory feeder for sorting, followed by manual adjustment of the orientation and quantity. Neither method achieves full automation, and manual operation suffers from significant efficiency bottlenecks.

[0004] The traditional model has significant drawbacks: First, it is both inefficient and inaccurate. The manual feeding rate is far lower than the packaging machine's capacity, and the long-term repetitive counting and feeding can easily lead to fatigue, resulting in incorrect placement of the pen bodies, requiring rework and verification, which further slows down the production pace. Second, there is an objective risk to quality. Although contamination can be controlled through protection during manual operation, the pen tips are still prone to deformation and damage due to improper handling. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that manual feeding is inefficient, prone to counting errors, and can cause damage due to improper placement.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic feeding mechanism for marker pens in a three-dimensional packaging machine, including a housing, a material bin arranged in an array within the housing, and a discharge hopper fixed at the bottom of the material bin; a fixed plate is fixedly installed at the bottom of the housing, and the fixed plate has a second feeding groove that is directly opposite the bottom outlet of the discharge hopper; a first baffle is horizontally slidably installed on the top of the fixed plate to switch the communication state between the second feeding groove and the discharge hopper; a discharge groove corresponding to the second feeding groove is opened on the bottom plate of the housing; and a second baffle is horizontally slidably installed on the bottom of the fixed plate to receive material at the second feeding groove and transfer the marker pens to the discharge groove.

[0007] Preferably, a support is fixedly installed inside the shell, and the hopper is vertically fixed to the side wall of the support.

[0008] Preferably, a first cylinder is horizontally fixed inside the housing, and a first connecting block is fixedly connected to the output end of the first cylinder, and the first connecting block is fixedly connected to the first baffle. The first baffle is attached to the top surface of the fixed plate.

[0009] Preferably, the first baffle is provided with a first feeding trough, and the bottom opening of the discharge hopper, the first feeding trough, the second feeding trough and the discharge trough are of the same size.

[0010] Preferably, a second cylinder is horizontally fixed inside the housing, and a second connecting block is fixed to the output end of the second cylinder and fixedly connected to the second baffle through the second connecting block. A third feeding groove for conveying marker pens is opened on the second baffle. The bottom ends of both ends of the fixed plate are fixed to the bottom plate of the housing through pads. The second baffle is slidably arranged between the fixed plate and the bottom plate of the housing.

[0011] Preferably, the cross-sections of the bottom openings of the first feeding trough, the second feeding trough, the third feeding trough, the discharge trough, and the discharge hopper are all adapted to the external shape of the marker pen.

[0012] Preferably, the inner bottom of the housing is provided with a cavity.

[0013] This utility model provides an automatic feeding mechanism for marker pens in a three-dimensional packaging machine, which has the following beneficial effects.

[0014] 1. Through the combined design of array-type hoppers and automated feeding structure, manual feeding and counting operations are completely replaced. The array-distributed hoppers can simultaneously store multiple specifications or multiple sets of markers. The first cylinder drives the first baffle to slide, and the material is discharged from the hopper through the precise docking of the first and second feeding troughs. The second cylinder drives the second baffle to complete the receiving and transfer of materials. The entire process requires no manual intervention, which improves the feeding efficiency and perfectly matches the high-efficiency operation rhythm of the three-dimensional packaging machine. It solves the problem of the imbalance between the traditional manual feeding rate and the packaging machine's capacity, and greatly improves the turnover efficiency of the entire production line.

[0015] 2. Precise control of material feeding quantity is achieved through quantitative storage in the hopper and precise switching of baffles. The first discharge chute of the first baffle is perfectly matched with the dimensions of the discharge hopper and the second discharge chute. Only a fixed number of markers are allowed to fall into the third discharge chute of the second baffle at a time, avoiding quantity deviations caused by fatigue and distraction during manual counting. This mechanism achieves zero counting error through the rigid constraints of the mechanical structure, eliminating the need for subsequent rework and verification, completely eliminating packaging defects caused by quantity errors, and improving the production qualification rate.

[0021] like Figures 1 to 4 As shown, this utility model provides an automatic feeding mechanism for marker pens in a three-dimensional packaging machine, including a housing 1, a material bin 3 arranged in an array within the housing 1, and a discharge hopper 4 fixed at the bottom of the material bin 3; a fixing plate 8 is fixedly installed at the bottom of the housing 1, and the fixing plate 8 has a second feeding groove 13 that is directly opposite the bottom outlet of the discharge hopper 4; a first baffle 7 is horizontally slidably installed on the top of the fixing plate 8 to switch the communication state between the second feeding groove 13 and the discharge hopper 4; a discharge groove 15 corresponding to the second feeding groove 13 is opened on the bottom plate of the housing 1; and a second baffle 11 is horizontally slidably installed on the bottom of the fixing plate 8 to receive material at the second feeding groove 13 and transfer the marker pens to the discharge groove 15.

[0022] Place the marker pen into the hopper 3, ensuring its orientation aligns with the bottom outlet of the discharge hopper 4 to allow it to fall smoothly. Before loading the marker pen, the first baffle 7 is in a closed position, blocking the bottom outlet of the discharge hopper 4. Then, control the movement of the first baffle 7 until it connects the first discharge trough 12 with the second discharge trough 13 on the fixed plate 8. The marker pen then passes through the first baffle 7 and enters the second discharge trough 13. And maintain the connection, then control the third feeding trough 14 in the second baffle 11 to connect with the second feeding trough 13, so that the marker pen enters the third feeding trough 14, control the second baffle 11 to move, so that the third feeding trough 14 drives a fixed number of marker pens inside it to the state of connecting with the discharge trough 14, and the marker pens in the third feeding trough 14 fall through the discharge trough 15, and realize automatic feeding; control the third feeding trough 14 to move back and forth, so as to continuously feed a fixed number of marker pens.

[0023] like Figure 1As shown. A bracket 2 is fixedly installed inside the housing 1, and the hopper 3 is vertically fixed to the side wall of the bracket 2. The hopper 3 is installed in an array through the bracket 2. The first discharge trough 12, the second discharge trough 13 and the third discharge trough 14 on the first baffle 7, the fixing plate 8 and the second baffle 11 are arranged corresponding to the hopper 3, which enables accurate batch feeding of marker pens.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a first cylinder 5 is horizontally fixed inside the housing 1. The output end of the first cylinder 5 is fixedly connected to a first connecting block 6, and is fixedly connected to the first baffle 7 through the first connecting block 6. The first baffle 7 is attached to the top surface of the fixed plate 8. The first cylinder 5 drives the first baffle 7 to move horizontally, and the feeding state of the discharge hopper 4 can be switched during the reciprocating movement of the first baffle 7.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a second cylinder 9 is horizontally fixed inside the housing 1. A second connecting block 10 is fixed to the output end of the second cylinder 9 and is fixedly connected to the second baffle 11 through the second connecting block 10. A third feeding groove 14 for conveying marker pens is opened on the second baffle 11. The bottom ends of the fixed plate 8 are fixed to the bottom plate of the housing 1 through pads. The second baffle 11 is slidably arranged between the fixed plate 8 and the bottom plate of the housing 1. The second cylinder 9 drives the second baffle 11 to move. During the reciprocating movement of the second baffle 11, the third feeding groove 14 inside the second baffle 11 continuously loads and unloads materials. Due to the fixed volume of the third feeding groove 14, the quantity of materials unloaded each time is accurate.

[0026] like Figure 4 As shown, to ensure that the marker in the hopper 4 can smoothly enter the third discharge trough 14 in the second baffle 11, and that the marker is continuously fed into the discharge trough 15 via the third discharge trough 4, the cross-sections of the first discharge trough 12, the second discharge trough 13, the third discharge trough 14, the discharge trough 15, and the bottom end of the discharge hopper 4 are all adapted to the external shape of the marker.
