Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and specifically discloses a bagging device for packaging skinless sausages. Background Technology

[0002] Skinless sausages (such as Frankfurt sausages and hot dogs) are a common type of meat product. They are characterized by the absence of a traditional casing, resulting in a more delicate texture. Compared to sausages wrapped in traditional casings, skinless sausages eliminate the need for natural or artificial casings during production, reducing costs and avoiding quality issues caused by casing breakage or shrinkage. However, due to the lack of casing protection, skinless sausages are more susceptible to mechanical damage or contamination during subsequent packaging, thus placing higher demands on packaging processes.

[0003] The production of skinless sausages typically involves filling, shaping, cooking, and cooling, culminating in packaging. Packaging not only affects the product's appearance and shelf life but also directly impacts the convenience of transportation, storage, and end-user sales. Currently, skinless sausage packaging primarily relies on manual bagging. Workers manually place each sausage into a pre-made bag and then seal it with a sealing machine. While this method offers high flexibility and is suitable for small-batch production, it is inefficient, limited by the speed of manual operation, and difficult to integrate with modern high-speed production lines, thus hindering capacity expansion. Furthermore, human contact with the product can easily introduce contamination, failing to meet food processing hygiene standards. Therefore, a bagging device for skinless sausage packaging is needed to address this issue. Utility Model Content

[0004] This utility model proposes a bagging device for skinless sausage packaging. Through clamping, conveying, bag supporting and unloading mechanisms, it significantly improves the packaging efficiency of skinless sausages and reduces manual contact, ensuring hygiene and safety.

[0005] This utility model is implemented as follows: a bagging device for packaging skinless sausages includes a workbench. The upper surface of the workbench is provided with a clamping and conveying mechanism, a bag supporting mechanism, and a feeding mechanism. The bag supporting mechanism includes two support plates fixedly connected to the upper surface of the workbench. A lead screw is rotatably connected between the two support plates. A first servo motor with its output end fixedly connected to the lead screw is installed on the outer wall of one of the support plates. Slide plates are threaded to both ends of the outer wall of the lead screw. Air chambers are provided on the outer walls of the two slide plates facing each other. Multiple suction cups are connected to the outer walls of the two air chambers facing each other. Air pumps with air inlets connected to the air chambers are installed on the outer walls of the two air chambers facing away from each other. An infrared sensor is installed on the inner wall of one of the support plates.

[0006] As a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, the feeding mechanism includes a hopper, the discharge port of the hopper is fixedly connected to a feeding plate via a connecting rod, and the other end of the feeding plate is provided with a feeding pipe located above the bag supporting mechanism.

[0007] As a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, the clamping and conveying mechanism includes four rotating rollers rotatably connected to the upper surface of the workbench via rotating shafts, a conveyor belt sleeved on the outer wall of the four rotating rollers, two third servo motors installed on the lower surface of the workbench with their output ends fixedly connected to two rotating rollers on one side, two limiting blocks fixedly connected to the upper surface of the workbench and respectively located inside the two conveyor belts, and two limiting rods fixedly connected to the upper surface of the limiting blocks via connecting rods.

[0008] As a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, the bag-supporting mechanism further includes a slide bar fixedly connected between two support plates, and both slide plates are slidably connected to the slide bar.

[0009] As a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, the feeding mechanism further includes a distributing roller rotatably connected to the inside of the hopper via a rotating shaft, and a second servo motor with its output end fixedly connected to the distributing roller is installed on the outer wall of the hopper.

[0010] In a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, the threads at both ends of the outer wall of the lead screw are in opposite directions.

[0011] In a preferred embodiment of the bagging device for packaging skinless sausages according to this utility model, a control panel is provided on the outer wall of one of the support plates, and the first servo motor, the second servo motor, the third servo motor and the infrared sensor are all electrically connected to the control panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the linkage design of the clamping conveyor mechanism, infrared sensor and bag opening mechanism, the bag opening can be accurately opened; combined with the quantitative feeding mechanism of the dispensing roller, the skinless sausage can be continuously and quickly put into the packaging bag. Compared with the traditional manual bagging method, the operation process of this device is seamlessly connected, which can match the high-speed production rhythm, effectively solve the bottleneck problem of low efficiency of manual operation, and greatly improve the production capacity.

[0014] 2. The device adopts a fully mechanical operation mode. From opening the bag to dispensing the skinless sausages, no manual intervention is required, avoiding direct contact between operators and the product or the inner wall of the packaging bag.

[0023] Please see Figure 1-5 A bagging device for packaging skinless sausages includes a workbench 1. The upper surface of the workbench 1 is provided with a clamping and conveying mechanism, a bag supporting mechanism, and a feeding mechanism. The bag supporting mechanism includes two support plates 6 fixedly connected to the upper surface of the workbench 1. A lead screw 7 is rotatably connected between the two support plates 6. A first servo motor 9 with its output end fixedly connected to the lead screw 7 is installed on the outer wall of one of the support plates 6. Slide plates 10 are threaded to both ends of the outer wall of the lead screw 7. Air chambers 11 are provided on the outer walls of the two slide plates 10 facing each other. Multiple suction cups 12 are connected to the outer walls of the two air chambers 11 facing each other. Air pumps 13 with air inlets connected to the air chambers 11 are installed on the outer walls of the two air chambers 11 facing away from each other. An infrared sensor 20 is installed on the inner wall of one of the support plates 6.

[0024] In this embodiment: the operator puts the packaging bags into the clamping and conveying mechanism in sequence, and the clamping and conveying mechanism conveys the packaging bags to the right. When the infrared sensor 20 detects that the packaging bag has been conveyed to the bag opening mechanism, the bag opening mechanism opens the bag opening, and then the unloading mechanism puts the skinless sausage into the packaging bag, which reduces the labor intensity of the operator.

[0025] The bag-holding mechanism operates as follows: the first servo motor 9 is started, which drives the lead screw 7 to rotate, thereby causing the two slide plates 10 to slide relative to each other along the slide rod 8, which in turn causes the two air chambers 11 to move relative to each other, so that the suction cup 12 is pressed against both sides of the bag opening. The two air pumps 13 are started, and the air pumps 13 generate negative pressure in the air chambers 11, which in turn sucks the bag opening through the suction cup 12. The first servo motor 9 drives the lead screw 7 to rotate in the opposite direction, which in turn causes the two slide plates 10 to move in opposite directions. The two slide plates 10 further drive the two air chambers 11 to move in opposite directions, which in turn opens the bag opening through the suction cup 12.

[0026] As a technical optimization of this utility model, the feeding mechanism includes a hopper 14, and the discharge port of the hopper 14 is fixedly connected to a feeding plate 15 through a connecting rod. The other end of the feeding plate 15 is provided with a feeding pipe 16 located above the bag support mechanism.

[0027] In this embodiment: the operator puts the skinless sausage into the hopper 14 along the width direction of the hopper 14. The skinless sausage is rotated by the material distribution roller 18 and falls downward onto the material feeding plate 15, and then falls into the material feeding pipe 16. It then falls into the packaging bag through the material feeding pipe 16. The operation is simple.

[0028] As a technical optimization of this utility model, the clamping and conveying mechanism includes four rotating rollers 2 rotatably connected to the upper surface of the workbench 1 via rotating shafts, conveyor belts 3 sleeved on the outer walls of the four rotating rollers 2, two third servo motors 19 installed on the lower surface of the workbench 1 with their output ends fixedly connected to two rotating rollers 2 on one side, two limiting blocks 4 fixedly connected to the upper surface of the workbench 1 and respectively located inside the two conveyor belts 3, and two limiting rods 5 fixedly connected to the upper surface of the limiting blocks 4 via connecting rods.

[0029] In this embodiment: two third servo motors 19 are started synchronously (the rotation of the two third servo motors 19 is in opposite directions). The third servo motors 19 drive one of the rollers 2 to rotate, which in turn drives the two conveyor belts 3 to rotate (the opposite sides of the two conveyor belts 3 are tightly abutted together). The packaging bag is placed between the two conveyor belts 3, thereby clamping the lower end of the packaging bag and conveying it to the right. The upper side of the packaging bag is limited by two limiting rods 5 to prevent the packaging bag from tipping over.

[0030] As a technical optimization of this utility model, the bag-supporting mechanism also includes a slide bar 8 fixedly connected between two support plates 6, and both slide plates 10 are slidably connected to the slide bar 8.

[0031] In this embodiment, the slide bar 8 is used to limit the sliding plate 10, so that the sliding plate 10 moves back and forth stably.

[0032] As a technical optimization of this utility model, the feeding mechanism also includes a distributing roller 18 that is rotatably connected to the inside of the hopper 14 via a rotating shaft, and a second servo motor 17 with its output end fixedly connected to the distributing roller 18 is installed on the outer wall of the hopper 14.

[0033] In this embodiment: the second servo motor 17 is started, and the second servo motor 17 drives the material distribution roller 18 to rotate. The outer wall of the material distribution roller 18 is provided with multiple grooves that match the skinless sausage, so that the skinless sausage is fed out one by one.

[0034] As a technical optimization of this utility model, the thread directions at both ends of the outer wall of the lead screw 7 are opposite.

[0035] In this embodiment, by setting the thread directions at both ends of the outer wall of the lead screw 7 to be opposite, the lead screw 7 can drive the two slide plates 10 to move synchronously relative to each other or in opposite directions when it rotates.

[0036] As a technical optimization of this utility model, a control panel is provided on the outer wall of one of the support plates 6, and the first servo motor 9, the second servo motor 17, the third servo motor 19 and the infrared sensor 20 are all electrically connected to the control panel.

[0037] In this embodiment: The control panel facilitates the normal operation of the first servo motor 9, the second servo motor 17, and the third servo motor 19. The control panel can be an industrial-grade programmable logic controller (PLC), such as the Siemens SIMATIC S7-1200 series.

[0038] The working principle and usage process of this utility model are as follows: First, the skinless sausage is placed into the hopper 14 along its width. Then, two third servo motors 19 are started simultaneously. The third servo motors 19 drive one side roller 2 to rotate, which in turn drives the two conveyor belts 3 to rotate. Next, the packaging bag is placed between the two conveyor belts 3, thus clamping the lower end of the packaging bag and conveying it to the right. Two limiting rods 5 are used to limit the upper side of the packaging bag to prevent it from tipping over. When the infrared sensor 20 detects that the packaging bag has been conveyed to the bag-supporting mechanism, the infrared sensor 20 transmits a signal to the control panel. The control panel starts the first servo motor 9, which drives the lead screw 7 to rotate, thereby driving the two slide plates 10 along the slide rod 8. The sliding mechanism causes the two air chambers 11 to move relative to each other, causing the suction cups 12 to press against both sides of the bag opening. Then, the control panel activates the two air pumps 13, which generate negative pressure in the air chambers 11, thereby sucking the bag opening through the suction cups 12. Then, the first servo motor 9 drives the lead screw 7 to rotate in the opposite direction, thereby causing the two sliding plates 10 to move in opposite directions. The two sliding plates 10 further drive the two air chambers 11 to move in opposite directions, thereby opening the bag opening through the suction cups 12. Then, the control panel continues to activate the second servo motor 17, which drives the distributing roller 18 to rotate. The skinless sausage falls downward onto the feeding plate 15 through the rotation of the distributing roller 18, and then falls into the feeding pipe 16, and then into the packaging bag through the feeding pipe 16, reducing the labor intensity of the operators.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
