Description

Technical Field

[0001] This utility model relates to the field of food packaging machinery technology, and in particular to a packaging machine with a debris suction device. Background Technology

[0002] In the meat processing industry, after meat is packaged as a whole (usually using plastic film), it needs to be further cut into multiple independent products according to commercial specifications (e.g., cutting one row into several products). This cutting process is usually completed by the cutting mechanism of the packaging machine. However, the packaging film easily generates plastic waste during the cutting process. This waste is random and scattered, and if it is not cleaned up in time, it will cause many problems: on the one hand, the waste will fall onto the production table, conveyor mechanism and product surface, polluting the production environment and affecting the hygiene quality of the product; on the other hand, the accumulated waste may jam the moving parts of the cutting mechanism or conveyor mechanism, leading to equipment failure and reducing production efficiency; at the same time, manual cleaning of waste at regular intervals requires interrupting the production process, increasing labor costs and further affecting the continuity of production.

[0003] Chinese utility model patent CN210311209U discloses a packaging film divider for a multi-row packaging machine, belonging to the field of packaging film dividing. It achieves efficient dividing of packaging film by setting up an anti-film-retraction roller mechanism, a one-way wheel, an adjusting wheel, and multiple sets of dividing circular blades, solving problems such as uneven cutting surfaces and complex operation. Furthermore, the dividing circular blades are made of ultra-hard alloy material, resulting in a long service life. However, this existing technology only focuses on optimizing the dividing function of the packaging film and does not consider the problem of cleaning up waste during the cutting process. Long-term use will still face defects such as environmental degradation, equipment failure, and decreased production efficiency caused by the accumulation of such waste, failing to meet the requirements of clean production. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes a packaging machine with a debris suction device, which solves the problem that the waste generated during the cutting process of existing packaging machines cannot be cleaned up in real time.

[0005] The technical solution of this utility model is implemented as follows: A packaging machine with a debris suction device includes a machine body, a support shaft on the machine body, and dividers evenly spaced on the support shaft; the machine body is provided with a double-headed dust suction pipe, and a plurality of dust suction hoods that cooperate with the dividers are provided on the double-headed dust suction pipe; both ends of the double-headed dust suction pipe are connected to a dust collection bin, the dust collection bin is connected to a negative pressure unit, and a filter assembly is provided inside the dust collection bin; the machine body is provided with a plurality of supports that correspond to the dividers respectively, and a conveying mechanism is provided on the machine body.

[0006] Preferably, the divider includes several pairs of cutter holders sleeved on the support shaft. Each cutter holder is equipped with a hob and a set screw that mates with the support shaft. The spacing between the cutter holders can be adjusted by adjusting the set screws to accommodate different cutting requirements.

[0007] Preferably, the upper end of the dust hood is connected to a double-headed dust suction pipe, and the bottom of the dust hood has an opening that mates with the blade holder and the rotary cutter. The side wall of the opening has a U-shaped groove that mates with the support shaft. A gap is left between the U-shaped groove and the side wall of the support shaft. The U-shaped groove allows the dust hood to avoid the support shaft, ensuring that the dust hood fits tightly against the cutting area of ​​the divider.

[0008] Preferably, the support includes several support seats fixedly mounted on the machine body, each support seat having a support block, and each support block having a cutting groove. The cutting groove cooperates with a roller cutter, with the lower end of the roller cutter extending into the cutting groove to cut and segment the packaged product. The conveying mechanism includes several bottom conveyor belts mounted on the base, with the bottom conveyor belts respectively positioned between adjacent supports.

[0009] Preferably, the dual-head suction pipe includes a U-shaped pipe body, which is fixedly mounted on the machine body. Several suction ports are opened on one side of the U-shaped pipe body, and the suction hoods correspond one-to-one with the suction ports. Both open ends of the U-shaped pipe body are provided with connecting flanges, which are respectively connected to connecting pipes. The connecting pipes are all connected to the dust collection bin. The structural design of the U-shaped pipe body enables the negative pressure suction to be evenly distributed to each suction hood, ensuring consistent dust removal effect.

[0010] Preferably, the dust collection bin includes a bin body with a lid. The lid has a pair of first connection ports for connecting to respective connecting pipes. The bottom side wall of the bin body has a second connection port for connecting to a negative pressure unit. The filter assembly includes an inner support shell fixedly disposed within the bin body. The inner support shell communicates with the inner end of the second connection port, and an inclined filter screen is disposed on the inner support shell. The negative pressure unit includes a negative pressure fan connected to the second connection port.

[0011] The beneficial effects of this utility model are: While the cutter is cutting the packaged products, the negative pressure unit uses suction to capture the waste generated during cutting in real time through the dust hoods. This waste is then transported to the dust collection bin via a dust extraction pipe, where a filter assembly intercepts and collects it. This effectively solves the core problem of timely waste removal in existing technologies, eliminating the need for regular manual cleaning, preventing production interruptions, and significantly improving production continuity and efficiency. It also prevents waste from clogging moving parts, reducing equipment failures, extending equipment lifespan, and further enhancing production continuity and efficiency. Furthermore, the dual-head suction pipes ensure even distribution of negative pressure suction to each dust hood. The compact overall structure requires no major modifications to existing equipment, making installation and maintenance convenient and applicable to a wide range of applications.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 , 5 As shown in Embodiment 1, a packaging machine with a debris suction device includes a body 1, a support shaft 2 on the body 1, and dividers 3 evenly spaced on the support shaft 2. The body 1 has a double-headed suction pipe 4, with several suction hoods 5 that cooperate with the dividers 3. Both ends of the double-headed suction pipe 4 are connected to a dust collection bin 6, which is connected to a negative pressure unit. A filter assembly 7 is installed inside the dust collection bin 6. The body 1 also has several supports 8 corresponding to the dividers 3, and a conveying mechanism 9. In this embodiment, while the dividers are cutting the packaged product, the negative pressure suction provided by the negative pressure unit captures the debris generated during cutting in real time through the suction hoods and transports it to the dust collection bin via the suction pipe. The filter assembly then intercepts and collects the debris, achieving timely cleaning.

[0016] Specifically in this embodiment, such as Figure 3 As shown, the divider 3 includes four pairs of cutter holders 31 sleeved on the support shaft 2, adapted to the need to divide three rows of product packaging into three rows. Each cutter holder 31 is equipped with a hob 32, which is made of conventional carbide material and features a sharp and wear-resistant blade. Each cutter holder 31 is equipped with a set screw that mates with the support shaft 2. The end of the set screw abuts against the side wall of the support shaft 2 to fix the cutter holder 31. Loosening the set screw allows adjustment of the spacing between the cutter holders 31 along the axial direction of the support shaft 2, adapting to the cutting of products of different widths.

[0017] As a further optional implementation, the support shaft is rotatably connected to the machine body 1 via bearings. A drive motor is fixedly installed on the machine body. The output end of the drive motor is connected to the end of the support shaft via a belt drive pair, so that the support shaft can be driven to rotate by the drive motor, which in turn drives the cutter holder and the hob to rotate, thereby making it easier to divide the product packaging.

[0018] Example 2, based on Example 1, such as Figure 2 As shown, the upper end of the dust hood 5 is connected to the double-headed dust suction pipe 4. The dust hood 5 is an inverted trapezoidal cover, made of thin plate, and welded and fixed to the double-headed dust suction pipe 4. The bottom of the dust hood 5 is provided with an opening 51 that cooperates with the blade holder 31 and the roller cutter 32. The size of the bottom opening is adapted to the shape of the blade holder and the roller cutter to meet the installation space requirements.

[0019] Furthermore, the side wall of the opening 51 is provided with a U-shaped groove 52 that mates with the support shaft 2. A gap is left between the U-shaped groove 52 and the side wall of the support shaft 2. This gap ensures that the normal rotation of the support shaft is not interfered with, and also reduces the leakage of negative pressure suction, thus ensuring the dust collection effect.

[0020] In addition, such as Figure 4 As shown, the support 8 includes several support seats 81 fixedly mounted on the machine body 1. Each support seat 81 corresponds to a divider. Support blocks 82 are provided on the support seats 81. Cutting grooves 83 are provided on the support blocks 82. The cutting grooves 83 cooperate with the roller cutter 32. Specifically, in this embodiment, the support blocks are made of polyurethane material. Cutting grooves are provided on their top surfaces. The width of the cutting grooves is slightly larger than the thickness of the roller cutter. The lower end of the roller cutter extends into the cutting grooves and cooperates with the support blocks to cut and divide the packaged products.

[0021] In addition, the conveying mechanism 9 includes several bottom conveyor belts 91 disposed on the base, and the bottom conveyor belts 91 are respectively disposed between adjacent supports 8. Specifically, in this embodiment, the bottom conveyor belts are made of conventional PU material and are driven by a geared motor. The three sets of bottom conveyor belts are respectively disposed between adjacent supports, and the top surface of the bottom conveyor belts is flush with the top surface of the support blocks to ensure stable product conveying.

[0022] In Example 3, based on Example 2, the dual-head suction pipe 4 includes a U-shaped pipe body 41 made of stainless steel pipe bent into shape. The U-shaped pipe body 41 is fixedly mounted on the machine body 1. Several suction ports are opened on one side of the pipe body of the U-shaped pipe body 41, and the number of suction ports is consistent with the number of suction hoods and corresponds one-to-one. Both open ends of the U-shaped pipe body 41 are provided with connecting flanges 42, and are respectively connected to connecting pipes 43 through connecting flanges 42. The connecting pipes 43 are both connected to the dust collection bin 6.

[0023] In addition, such as Figure 5 As shown, the dust collection bin 6 includes a bin body 61, and a bin lid 62 is provided on the bin body 61. In this embodiment, the bin body is made of stainless steel, and the bin lid is detachably connected to the bin body by bolts or threads. The bin lid 62 is provided with a pair of first connection ports 63, which are respectively sealed to two connecting pipes 43. A second connection port 64 is provided at the bottom of the side wall of the bin body 61. The negative pressure unit includes a negative pressure fan 10. The second connection port 64 is sealed to the air inlet of the negative pressure fan 10 through a pipe. The negative pressure fan is a centrifugal negative pressure fan with appropriate power, and the air outlet is provided with a conventional fan silencer to reduce noise.

[0024] As a further specific embodiment, the filter assembly 7 includes an inner support shell 71 fixedly disposed within the barrel 61. The inner support shell 71 communicates with the inner end of the second connection port 64. The inner support shell 71 has an inclined opening, and a filter screen 72 is disposed at the opening. The filter screen is made of stainless steel or nylon, and the edge of the filter screen is sealed to the inner wall of the barrel, ensuring that airflow must pass through the filter screen before entering the inner support shell. In addition, the inclined opening of the inner support shell and the filter screen disposed at the inlet of the inner support shell allow some of the impurities or debris adsorbed on the filter screen to slide down to the bottom of the barrel under gravity when the negative pressure fan stops working, facilitating the restart of the equipment and the cleaning of debris.

[0025] The working process of this embodiment is as follows: Before starting the equipment, adjust the blade spacing of the divider according to the product cutting specifications, and fix the blade holders with set screws to ensure precise fit between the roller blade and the blade groove of the support block. Start the negative pressure fan and conveyor mechanism. The negative pressure fan generates negative pressure, creating a negative pressure environment inside the double-headed dust collection pipe and dust collection hood. Place the packaged meat product on the bottom conveyor belt, which transports the product between the support block and the roller blade. Driven by a motor, the support shaft rotates the roller blade, which, in conjunction with the blade groove of the support block, cuts the product into multiple individual specifications.

[0026] Plastic waste generated during the cutting process is sucked in through the opening of the dust hood under negative pressure, and then enters the dust collection bin through the U-shaped tube and connecting pipe. Inside the dust collection bin, the waste is intercepted by the filter screen and slides down the inclined screen to the bottom of the bin. Clean air enters the negative pressure fan through the inner support shell and the second connecting port, and is discharged from the outlet. The cut products continue to be conveyed to the next process by the bottom conveyor belt.

[0027] After the equipment has been running for a period of time, turn off the negative pressure fan, remove the lid of the dust collection bin, clean the waste collected inside the bin, and reinstall the lid after cleaning to continue operation.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
