Description

Technical Field

[0001] This utility model relates to the field of mechanical packaging equipment technology, and in particular to a packing machine. Background Technology

[0002] Currently, the packaging process is an essential step in the production of medical packaging bags. Traditional packaging tables are usually fixed in design. Due to the low height of the lower packaging rack, workers need to maintain a bent-over posture for extended periods, which can easily lead to lower back fatigue and even occupational injuries. Furthermore, existing packaging tables often use hydraulic mechanisms to drive the upper packaging rack for clamping operations. Because hydraulic mechanisms pose a risk of oil leakage, and because they are typically located at the top to drive the upper packaging rack up and down to clamp the bags, this not only easily contaminates the working environment but may also affect the packaging quality.

[0003] With the improvement of medical supply production standards, higher requirements are placed on the efficiency, ergonomics, and environmental performance of packaging equipment. Therefore, this utility model proposes a packaging machine to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0014] Preferably, the second limiting component includes four limiting bolts, and the support frame is threaded with four limiting bolts, all of which are threadedly connected to the lower packing plate frame.

[0015] Preferably, a limiting strip is fixedly installed on the bottom side of the lower support strip, and multiple limiting slots are provided on the lower packing plate frame. The lower support strip is installed on the lower packing plate frame by the limiting strip and the limiting slots.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Reference Figure 1-7 The baling machine includes a support frame 1, a top plate 11, an upper baling plate frame 2, a lower baling plate frame 3, a hydraulic cylinder 4, multiple upper support bars 201 and multiple lower support bars 301;

[0032] The top plate 11 is fixedly installed on the top of the support frame 1. The upper packing plate frame 2 and the lower packing plate frame 3 are both slidably installed on the support frame 1 and arranged sequentially from top to bottom. Multiple upper support bars 201 are fixedly installed on the bottom side of the upper packing plate frame 2 and arranged parallel to each other. Multiple lower support bars 301 can be detachably installed on the lower packing plate frame 3 and arranged parallel to each other.

[0033] A screw sleeve 22 is rotatably mounted on the top plate 11, and a fixing stud 21 is fixedly mounted on the top side of the upper packing plate frame 2. The fixing stud 21 is threaded into the screw sleeve 22, which can adjust the height of the upper packing plate frame 2 when the screw sleeve 22 rotates. A rotating shaft 24 is rotatably mounted on the support frame 1. An adjusting wheel 241 and a bevel gear 25 are fixedly mounted on both ends of the rotating shaft 24, respectively. A bevel gear 23 that meshes with the bevel gear 25 is fixedly sleeved on the screw sleeve 22, which makes it easy for the operator to control the rotation of the screw sleeve 22 from the side of the support frame 1.

[0034] Two support pins are rotatably mounted on the support frame 1. The same strip plate 41 is fixedly mounted on one end of the two support pins that are close to each other. The hydraulic cylinder 4 is fixedly mounted on the strip plate 41. When the working end of the hydraulic cylinder 4 is disengaged from the lower packing plate frame 3, the tilt angle of the cylinder can be adjusted, which facilitates maintenance, disassembly and replacement.

[0035] A fixing seat 31 is fixedly installed at the center of the bottom side of the lower packing plate frame 3. The bottom side of the fixing seat 31 has an insertion groove. The working end of the hydraulic cylinder 4 is inserted into the insertion groove. The fixing seat 31 is threaded with a shoulder bolt 311 that passes through the working end of the hydraulic cylinder 4, which can effectively connect the working end of the hydraulic cylinder 4 to the lower packing plate frame 3 and also facilitate disassembly.

[0036] The support frame 1 is threaded with four limiting bolts 32, all of which are threaded to the lower packing plate frame 3. This limits the position of the lower packing plate frame 3 on the support frame 1, thereby facilitating the disassembly, assembly, and maintenance of the hydraulic cylinder 4.

[0037] In this embodiment, in order to prevent the fixing stud 21 from becoming disconnected from the screw sleeve 22, a limit block 211 is fixedly installed at the top of the fixing stud 21.

[0038] In this embodiment, in order to adjust the spacing between two adjacent lower support bars 301 according to the actual packaging needs, and at the same time ensure the installation stability of the lower support bars 301 after installation, a limiting strip 302 is fixedly installed on the bottom side of the lower support bar 301, and multiple limiting slots 303 are provided on the lower packaging plate 3. The lower support bar 301 is installed on the lower packaging plate 3 by the limiting strip 302 and the limiting slots 303.

[0039] The upper support bar 201 and the lower support bar 301 are provided with anti-slip textures 5 on the side that are close to each other to increase the friction between them and the packaged items. The anti-slip textures 5 are cross-shaped mesh protrusions.

[0040] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0041] To further improve the ergonomics of the equipment, the fixing stud 21 and the screw sleeve 22 in the first support adjustment assembly adopt a trapezoidal thread connection structure with a pitch of 4mm and a lead of 8mm. This ensures good self-locking performance during height adjustment and prevents the upper packing rack 2 from accidentally sinking due to gravity. Furthermore, a torque limiting mechanism is provided between the rotating shaft 24 and the second bevel gear 25. When the torque applied by the operator rotating the adjusting wheel 241 exceeds a preset value (e.g., 50 N·m), this mechanism will automatically slip, avoiding mechanical damage or the risk of misoperation due to excessive force.

[0042] A pressure sensor and a limit switch are installed in the control circuit of hydraulic cylinder 4 to detect the working status of hydraulic cylinder 4 and the position of lower packing rack 3. When hydraulic cylinder 4 pushes lower packing rack 3 to a set position (e.g., 50mm from the bottom of upper packing rack 2), the limit switch triggers a signal, and the control system automatically stops the hydraulic cylinder 4 to prevent overpressure damage to the equipment. At the same time, the pressure sensor continuously monitors the pressure changes of the hydraulic system. If the pressure rises abnormally (e.g., exceeding 10MPa), the system will automatically alarm and cut off the power source to ensure safe and reliable operation of the equipment.

[0043] Regarding the snap-fit ​​structure of the lower support strip 301, the limiting slots 303 are arranged at equal intervals along the transverse direction of the lower packaging plate 3, with a center distance of 50mm between two adjacent limiting slots 303, allowing for flexible adjustment of the installation position of the lower support strip 301 according to the size of the packaging bag. Each limiting strip 302 is 8mm wide and 60mm long, and has an elastic rubber pad layer with a thickness of 2mm on its bottom surface to enhance the friction between it and the limiting slot 303, preventing the lower support strip 301 from shifting or falling off during the packaging process.

[0044] To enhance the friction effect of the anti-slip texture 5, the cross-shaped mesh protrusion structure is composed of crisscrossing raised lines. Each raised line is 1.2 mm high and 2 mm wide, with a spacing of 5 mm, arranged orthogonally to form multiple diamond-shaped friction units. This structure has been experimentally verified to achieve a static friction coefficient of over 0.6 on the surface material of medical packaging bags (such as PET / PE composite film), significantly improving stability during packaging and effectively preventing slippage or misalignment of the packaging bag during compression.

[0045] During the initial debugging phase of the equipment, the operator can fine-tune the positioning of the lower packaging plate frame 3 using the limit bolts 32. Each limit bolt 32 is equipped with a scale ring, with a minimum adjustment accuracy of 0.5mm, to ensure that the lower packaging plate frame 3 and the upper packaging plate frame 2 remain parallel, with the error controlled within ±0.1°. This ensures uniform contact between the upper and lower support bars during the packaging process and avoids damage to the packaging bags caused by uneven local stress.

[0046] Furthermore, to address the issue of oil leakage and contamination in traditional hydraulic drive devices, the hydraulic cylinder 4 in this invention employs a closed-loop hydraulic circuit design and is equipped with a leakage detection device. This detection device includes a liquid collection tank located at the bottom of the hydraulic cylinder 4 and a liquid level sensor. When the detected leakage liquid volume exceeds 2ml, the system will issue a warning through the human-machine interface, reminding maintenance personnel to promptly check and replace the seals to prevent hydraulic oil from dripping into the packaging area and affecting product quality.

[0047] Working principle: When in use, first turn on the power, then control the limit bolt 32 to disengage from the lower packaging plate 3. Then, adjust the lower packaging plate 3 to a position that is easy to operate by using the hydraulic cylinder 4. Then, the operator can rotate the adjusting wheel 241 to drive the rotating shaft 24 to rotate. The rotating shaft 24 drives the second bevel gear 25 to rotate. The second bevel gear 25 drives the bevel gear 23 that meshes with it to rotate. The first bevel gear 23 drives the threaded sleeve 22 to rotate. The threaded sleeve 22 and the fixed stud 21 are connected by threads, so the fixed stud 21 can move up and down when the threaded sleeve 22 rotates. The fixed stud 21 drives the upper packaging plate 2 to adjust its height, so that the operator can operate according to the actual needs. After the adjustment is completed, place the medical packaging bag to be packaged on the multiple lower support bars 301 on the lower packaging plate 3. Then, start the hydraulic cylinder 4 to control the lower packaging plate 3 to move upward, so that it can cooperate with the upper packaging plate 2 to squeeze it, thus making it convenient for the operator to use the packaging rope to package it.

[0048] When the hydraulic cylinder 4 needs to be repaired or replaced, first adjust the lower packing plate frame 3 to a position where the limit bolt 32 can easily limit it, and then limit it with the limit bolt 32. Then, the operator can rotate the shoulder bolt 311 to disengage it from the working end of the hydraulic cylinder 4. At this time, control the hydraulic cylinder 4 to retract, so that it can be disengaged from the fixed seat 31. Then, rotate it based on the support pin as the center to adjust it to a state that is convenient for maintenance, so that the operator can easily repair or replace the hydraulic cylinder 4.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
