Description

Technical Field

[0001] This utility model belongs to the field of slaughtering equipment technology, and in particular relates to an automatic packaging machine for chilled fresh meat. Background Technology

[0002] Pillow packaging machines are the latest type of automatic continuous packaging equipment in China. They are highly automated, with a simple and stable transmission system, easy parameter settings, and are safe and reliable. They can not only complete discharge, packaging, and sealing in one go, but also effectively improve packaging efficiency.

[0003] Existing pillow-type packaging machines' automatic feeding devices can only feed at a fixed angle, unable to adjust the feeding angle according to user needs. This is particularly problematic for feeding large pieces of fresh pork, such as cuts of fresh meat. When connected to the production line, they cannot buffer a large number of products. In case of equipment failure or excessive feeding, they cannot provide sufficient product buffering. Furthermore, different products have different shapes and postures, causing products to enter the packaging machine incorrectly, increasing the risk of film detachment, jamming, and product cutting. This requires manual intervention to remove the material and restore the packaging film, significantly reducing packaging efficiency and product quality. Additionally, pushing chilled fresh meat products directly off the ordinary feeding conveyor is laborious due to the high friction between the meat and the flat plate.

[0004] Therefore, how to solve the above problems has become a key research topic in the existing technology field. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an automatic packaging machine for chilled fresh meat, which solves the above problems.

[0006] To achieve the above objectives, this utility model discloses an automatic packaging machine for chilled fresh meat, comprising:

[0007] A feeding conveyor line is used to transport chilled fresh meat, and a material guiding and buffering mechanism is provided on the side of the feeding conveyor line;

[0008] The feeding and buffering mechanism includes a buffer roller for temporarily storing chilled fresh meat, a support fixing plate, and a guiding device. The guiding device is disposed on the buffer roller and is used to adjust the posture of the chilled fresh meat. The buffer roller is installed on the feeding conveyor line through the support fixing plate.

[0009] And a packaging mechanism for packaging chilled meat, the packaging mechanism including a packaging machine conveyor line that abuts against the feed conveyor line;

[0010] The discharge conveyor line is in contact with the packaging machine conveyor line.

[0011] Compared with existing technologies, this application has the following advantages: During the conveying of chilled meat, if equipment malfunctions or there is a large amount of material being fed, the chilled meat can be temporarily stored on a buffer roller. Simultaneously, when feeding is needed, the chilled meat on the buffer roller can be pushed onto the conveying line. Therefore, by setting up the buffer roller, not only can the chilled meat be temporarily stored, but the friction between the chilled meat and the buffer roller is also low during pushing, saving time and effort. Furthermore, the design of the guiding device allows for adjustment of the posture and position of the chilled meat on the conveying line, ensuring that the chilled meat enters the packaging mechanism at a suitable angle, thereby reducing problems such as mold detachment, material jamming in the center seal, and product cutting during packaging.

[0012] Furthermore, the buffer roller and the support fixing plate are quick-release fixed together.

[0013] Furthermore, the lower end of the support fixing plate is connected to the support slide rail, the support slide rail is connected to the side plate of the feeding conveyor line, and the support slide rail can move back and forth relative to the side plate.

[0014] Furthermore, the guiding device includes guide plates located on both sides of the feeding conveyor line, the guide plates being used to straighten the posture of the chilled meat and position the chilled meat in the middle of the feeding conveyor line.

[0015] Furthermore, the guide plate is a guide roller.

[0016] Furthermore, the guide roller is a flow bar.

[0017] Furthermore, in accordance with the feeding direction of the packaging machine conveyor line, a bag maker, a center sealing film mechanism, and an end sealing and cutting mechanism are sequentially arranged above the packaging machine conveyor line.

[0018] Furthermore, the sealing mechanism includes a sealing paper pressing assembly, a film drop detection support plate, a film drop detection sensor, and a sealing heating assembly. The film drop detection support plate is disposed between the sealing paper pressing assembly and the sealing heating assembly.

The film drop detection sensor detects whether the film material has fallen off based on the reflectivity of the film material. Alternatively, the film drop detection support plate is disposed at the front end of the sealing paper pressing assembly, and the film drop detection sensor is fixed on the film drop detection support plate.

[0019] Furthermore, the end-seal cutting mechanism includes an anti-cut sensor bracket and an end-seal module. An anti-cut sensor is provided on the anti-cut sensor bracket, and the anti-cut sensor bracket is installed on the end-seal module.

[0020] Furthermore, the bag maker is a PE film bag maker. Attached Figure Description

[0029] 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.

[0030] like Figure 1-2 As shown, this utility model discloses an automatic packaging machine for chilled fresh meat, comprising:

[0031] Feeding conveyor line 1 is used to transport chilled fresh meat. A material guiding and buffering mechanism is provided on the side of feeding conveyor line 1.

[0032] The feeding and buffering mechanism includes a buffer roller 2 for temporarily storing chilled fresh meat, a support fixing plate 3, and a guide device 4. The guide device 4 is installed on the buffer roller 2 to adjust the posture of the chilled fresh meat. The buffer roller 2 is installed on the feeding conveyor line 1 through the support fixing plate 3.

[0033] And a packaging mechanism for packaging chilled meat, the packaging mechanism including a packaging machine conveyor line 5, the packaging machine conveyor line 5 abutting the feeding conveyor line 1;

[0034] The discharge conveyor line 6 is in contact with the packaging machine conveyor line 5.

[0035] It should be noted that the chilled fresh meat is fed into the packaging machine conveyor line 5 via the feeding conveyor line 1. The packaging machine conveyor line 5 carries the chilled fresh meat through the packaging mechanism, where the product packaging is completed. The packaging machine conveyor line 5 then transports the packaged chilled fresh meat to the discharge conveyor line 6, which transports the product to the designated location.

[0036] Compared with the prior art, this application has the following advantages: During the conveying of chilled meat on the feeding conveyor line 1, if equipment failure occurs or there is a large amount of material being fed, the chilled meat can be temporarily stored on the buffer roller 2. Simultaneously, when feeding is needed, the chilled meat on the buffer roller 2 can be pushed onto the feeding conveyor line 1. Therefore, the buffer roller 2 not only enables temporary storage of the chilled meat, but also reduces friction between the chilled meat and the buffer roller 2 during pushing, saving time and effort. Furthermore, the guide device 4 allows adjustment of the posture and position of the chilled meat on the feeding conveyor line 1, ensuring that the meat enters the packaging mechanism at a suitable angle, thereby reducing problems such as mold detachment, material jamming in the center seal, and product cutting during packaging.

[0037] There can be two material guiding and buffering mechanisms, which are symmetrically arranged on both sides of the feeding conveyor line 1 to increase the amount of chilled meat that can be buffered. After buffering, the product can be pushed down directly, saving manpower and improving packaging efficiency. For irregular material products, the guiding device 4 of the material guiding and buffering mechanism can constrain the product to the middle of the packaging machine in a standardized manner, reducing the failure rate of the equipment and improving packaging efficiency.

[0038] Following the above embodiments, more specifically, as Figure 2As shown, the buffer roller 2 and the support fixing plate 3 are quick-release fixed together. The buffer roller 2 is fixed to the buffer roller support frame with flat-head hex bolts. The design of the flat-head hex bolts makes it difficult for dirt to accumulate and facilitates cleaning. At the same time, the buffer roller support frame and the support fixing plate 3 can be quickly released through a snap-fit ​​structure, which facilitates the disassembly and cleaning of the buffer roller 2.

[0039] Following the above embodiment, more specifically, the lower end of the support fixing plate 3 is connected to the support slide rail 7, and the support slide rail 7 is connected to the side plate of the feeding conveyor line 1. The support slide rail 7 can move back and forth relative to the side plate. The side plate may be provided with elongated holes, and the support slide rail 7 is adjusted by inserting bolts into these holes, thereby adjusting the position of the guide device 4 so that the chilled meat enters the packaging machine at a set position.

[0040] Following the above embodiment, more specifically, the guiding device 4 includes guide plates located on both sides of the feeding conveyor line 1. The guide plates are used to straighten the posture of the chilled meat and position it in the middle of the feeding conveyor line 1, thereby reducing the failure rate of the equipment and improving packaging efficiency.

[0041] Following the above embodiments, more specifically, the guide plate is a guide roller, and the guide roller can be made of materials with low friction, such as flow strips, to reduce the friction between the chilled meat and the guide plate. At the same time, the cooperation between the two-sided feeding guide plates can also straighten the material and maintain the stability of the product material.

[0042] Following the above embodiments, more specifically, as Figure 3 and Figure 4 As shown, following the feeding direction of the packaging machine conveyor line 5, a bag maker 8, a center-sealing and film-sealing mechanism 9, and an end-sealing and cutting mechanism 10 are sequentially arranged above the packaging machine conveyor line 5. The bag maker 8 uses sheet-like PE film to wrap the product inside the packaging bag. The center-sealing and film-sealing mechanism 9 is responsible for completing the intermediate sealing of the packaging material. It typically includes a center-sealing paper-pressing assembly 11 for pulling the paper and a center-sealing heating assembly 14 for heating and pressing. These parts work together to ensure that the packaging material is accurately and firmly sealed together. The end-sealing and cutting mechanism 10 is installed after sealing to automatically cut and repackage the sealed packaging bags. Generally, the packaging machine automatically cuts out sealed packaging bags according to a set length and separates them.

[0043] Furthermore, such as Figure 3As shown, in one embodiment, the sealing mechanism 9 includes a sealing paper pressing assembly 11, a film detachment detection support plate 12, a film detachment detection sensor 13, and a sealing heating assembly 14. The film detachment detection support plate 12 is disposed between the sealing paper pressing assembly 11 and the sealing heating assembly 14. The film detachment detection sensor 13 is fixed on the film detachment detection support plate 12. The film detachment detection sensor 13 detects whether the film material has detached based on the reflectivity of the film material. The film detachment detection sensor 13 uses a fiber optic sensor to detect whether the film material has detached, which has high accuracy and simple structure. Throughout the entire process from the sealing paper pressing assembly 11 to the sealing heating assembly 14, the film detachment detection sensor 13 can continuously detect the film material. If the film material detaches, the film detachment detection sensor 13 will trigger an alarm, the equipment will stop working, and the equipment will be restarted after the operator reinstalls the film material. The equipment can then work normally, allowing the packaging film 17 to complete the sealing process.

[0044] Or, such as Figure 4 As shown, in another embodiment, a film-drop detection support plate 12 is provided at the front end of the sealing and pressing paper assembly 11. A film-drop detection sensor 13 is provided on the film-drop detection support plate 12. The film-drop detection sensor 13 is a U-shaped sensor. This sensor is added before the packaging film 17 enters the sealing and pressing paper assembly 11. The packaging film 17 has two pieces of film in the opening direction, each passing through the U-shaped sensor. During normal operation, the film-drop detection sensor 13 continuously detects the film. If the film falls off, the U-shaped sensor will trigger an alarm, the equipment will stop working, and the operator will need to reinstall the film before restarting the equipment. The equipment will then function normally, allowing the packaging film 17 to complete the sealing process.

[0045] Following the above embodiments, more specifically, as Figure 5 As shown, the end-sealing cutting mechanism 10 includes an anti-cutting sensor bracket 15 and an end-sealing module 16. An anti-cutting sensor 18 is mounted on the anti-cutting sensor bracket 15 and installed on the end-sealing module 16. The design of the anti-cutting sensor 18 prevents the cutter of the end-sealing cutting mechanism 10 from cutting the product, thus avoiding damage to the cutter. Specifically, the anti-cutting sensor 18 is a through-beam anti-cutting sensor. When the packaging film 17 containing the item is properly packaged, the through-beam anti-cutting sensor detects no abnormality at the sealing point, and the end-sealing cuts the film normally without triggering a sealing alarm. Conversely, when the item is inside the upper and lower sealing and cutting mechanism, the anti-cutting sensor 18 of the sealing and cutting mechanism is triggered, sending a signal to the upper and lower sealing and cutting motors. The upper and lower sealing and cutting motors stop working, preventing the cutter from cutting the item, thereby effectively preventing accidental cutting.

[0046] Following the above embodiments, more preferably, the bag maker 8 is a PE film bag maker. In the prior art, the packaging film 17 used in packaging machines is a composite film, but composite films are expensive and thick. Therefore, in this application, PE film is used instead of composite film, which is not only cheaper but also more resilient, less likely to be punctured by chilled meat, and has better performance.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
