Description

Technical Field

[0001] This invention relates to the field of automatic sausage packaging machinery technology, specifically an automatic sausage packaging machine. Background Technology

[0002] During the production and processing of sausages, automatic packaging machines are required to package them. During packaging, depending on the packaging requirements, sausages can be placed inside the packaging bag in either single or multiple groups.

[0003] In the process of using an automatic packaging machine to feed and package multiple sets of sausages into a packaging bag, in order to ensure the normal feeding of multiple sets of materials onto the packaging bag, the opening length of the packaging bag is generally set to be large during the feeding process to ensure the gaps when the sausages are fed. However, due to the existence of gaps, after multiple sets of sausages are fed, the sausages are tilted and intertwined with each other, which affects the subsequent packaging effect. Therefore, we propose an automatic sausage packaging machine. Summary of the Invention

In addition, the robotic arm component 103 and the pressure-reducing heat-sealing component 104 are conventional components for picking up materials and pressing and heat-sealing packaging bags, and their working principle and operation method are existing technology in this application, so they will not be described in detail here.

[0019] Also includes: The clamping assembly is set on the rotary table 102 for clamping and fixing the packaging bag after feeding. There are multiple sets of clamping assemblies, and the multiple sets of clamping assemblies are arranged in a circular array around the rotary table 102. A centering pusher component is set on the clamping component to center and push the sausages after they are placed inside the packaging bag. The feeding assembly is located inside the packaging machine housing 101 and is used to assist in the feeding and conveying of the sausages to be packaged; Additionally, a positioning component installed inside the packaging machine housing 101 for assisting in the positioning of the sausage during the feeding process toward the inside of the packaging bag, and an adsorption component for assisting in pulling the sides of the packaging bag during the positioning process. It should be noted that during the automatic packaging machine's sausage packaging process, a circular feeding cavity can be formed during the feeding process. The existence of the circular feeding cavity ensures sufficient space for the sausages to fall into the packaging, facilitating the rapid and stable complete feeding of the sausages into the packaging belt during subsequent packaging. After the packaging bag is pulled to form the feeding cavity, two adjacent feeding cavities are separated by two sets of positioning pressure plates 805 to prevent the sausages from tilting or intersecting each other during the sausage feeding and conveying process. Furthermore, after feeding, by pulling the packaging bag to both sides and pushing the sausages in the center inside the packaging belt, it is further possible to avoid local wrinkles, bulges, or uneven stress on the packaging bag caused by sausage deviation, thereby improving the aesthetics and consistency of the product packaging and enhancing the consumer's visual experience.

[0020] Preferably, the feeding assembly includes a first L-shaped frame 701 fixed inside the packaging machine housing 101, a guide bin 702 fixed on the first L-shaped frame 701, the guide bin 702 being located above the rotary table 102, and the guide bin 702 having multiple sets of feeding holes 703 for conveying and feeding sausages.

It is worth noting here that the packaging machine casing 101 is equipped with a conveying component for conveying the sausages toward the inside of the feed hopper 702. In this application, the conveying component is a conventional material conveying component, and its working principle and operation method are known technologies and will not be described in detail here.

It should be noted here that: the upward movement of the U-shaped frame 801 positions the two sets of positioning components on both sides of the packaging bag. After the U-shaped frame 801 rises, the first cylinder 807 drives the moving plate 803 to move towards the outside of the packaging bag. During the movement of the moving plate 803, the connecting action of the telescopic components drives the mounting frame 804 to move. During the movement of the mounting frame 804, the sets of ball bearings 806 on one side of each set of positioning pressure plates 805 on the mounting frame 804 and the suction cover 1001 on one side of the mounting frame 804 abut against the outside of the packaging bag. Through the pressing action of the multiple sets of ball bearings 806 on the positioning pressure plates 805 on both sides of the packaging bag against the outside of the packaging bag, the packaging bag to be fed is squeezed and positioned. It is worth noting here that the lifting component 802 is a conventional lifting drive component, and its working principle and operation method are existing technology in this application, so they will not be described in detail here.

It should be noted here that: through transmission, the pressure suction cover 1001 is brought into contact with the outside of the packaging bag. After the pressure suction cover 1001 is brought into contact with the outside of the packaging bag, through the driving action of the pressure suction pump 1003 and the connecting action of the air pipe 1002, one side of the packaging bag is adsorbed onto the pressure suction cover 1001.

[0024] The sliding assembly includes a fixed frame 1101 fixed on the mounting bracket 804. Multiple sets of connecting rods 1102 are slidably connected on the fixed frame 1101.

During the relative movement, the connecting plate 1103 is pulled away from the fixed frame 1101 by the traction of the pull rope 1203 by the L-shaped pull plate 1202 and the support of the support roller 1204.

[0026] Preferably, the clamping assembly includes two sets of L-shaped mounting bases 201 arranged symmetrically. A connecting assembly for auxiliary connection is provided between the L-shaped mounting bases 201 and the rotary table 102. Two sets of fixing rods 202 are fixed to the front side of the L-shaped mounting bases 201. A support plate 203 for positioning against the packaging bag is fixed to the front end of the fixing rods 202. A clamping plate 204 for auxiliary clamping and fixing is provided on the front side of the support plate 203. A second cylinder 205 for driving the clamping plate 204 is provided on the L-shaped mounting bases 201. It should be noted that: the packaging bag is grasped and moved by the robotic arm component 103. After grasping, the packaging bag is moved between the support plate 203 and the clamping plate 204 of the clamping assembly with the opening facing upward. After moving, the clamping plate 204 is moved towards the support plate 203 by the driving action of the second cylinder 205. During the movement, the packaging bag is fixed between the support plate 203 and the clamping plate 204, thus completing the installation and fixation of the packaging bag on the rotary table 102.

[0027] Preferably, the connecting assembly includes multiple sets of first T-shaped rods 301 slidably connected to the L-shaped mounting base 201, one end of each set of first T-shaped rods 301 being fixed to the rotary table 102, and a third spring 302 being sleeved on the outer side of the first T-shaped rods 301; It should be noted that: multiple sets of first T-shaped rods 301 facilitate the sliding guide connection of the L-shaped mounting base 201, and the third spring 302 facilitates the reset of the L-shaped mounting base 201 after movement.

[0028] Preferably, the centering pusher assembly includes a U-shaped pusher plate 401 for centering the sausage inside the packaging bag, a clamping plate 204 and a support plate 203 located between the U-shaped pusher plate 401, a guide assembly for auxiliary guiding connection between the U-shaped pusher plate 401 and the clamping plate 204, a third L-shaped frame 402 fixed on the rotary table 102, a mounting shaft 403 fixed on the third L-shaped frame 402, a connecting rod 404 rotatably connected to the mounting shaft 403, one side of the connecting rod 404 abutting against the L-shaped mounting seat 201, a transmission groove 405 opened on the connecting rod 404, a transmission pin 406 slidably connected to the transmission groove 405, one end of the transmission pin 406 fixed to the U-shaped pusher plate 401, and a transmission assembly for transmitting power to the L-shaped mounting seat 201 between the third L-shaped frame 402 and the L-shaped mounting seat 201. It should be noted here that: through transmission, the two sets of L-shaped mounting seats 201 on the clamping assembly are subjected to force and move away from each other. During the movement of the L-shaped mounting seats 201, the L-shaped mounting seats 201 abut against one side of the connecting rod 404. During the abutment process, the connecting rod 404 is subjected to force and rotates around the mounting shaft 403. During the rotation of the connecting rod 404, through the interaction of the transmission groove 405 and the transmission pin 406, the U-shaped push plate 401 is pushed towards the packaging bag. During the movement of the U-shaped push plate 401, the sausage placed inside the packaging bag is pushed towards the middle position of the packaging bag.

[0029] Preferably, the transmission assembly includes an iron block 601 fixed on the L-shaped mounting base 201, and an electromagnet 602 for magnetic attraction with the iron block 601 after being energized is mounted on the third L-shaped frame 402. It should be noted here that when the electromagnet 602 is energized, the magnetic force between the electromagnet 602 and the iron block 601 causes the two sets of L-shaped mounting seats 201 on the clamping assembly to move away from each other.

[0030] Preferably, the guide assembly includes multiple sets of second T-shaped rods 501 slidably connected to the U-shaped push plate 401, one end of the second T-shaped rod 501 is fixed to one side of the clamping plate 204, and a fourth spring 502 is sleeved on the outside of the second T-shaped rod 501; It should be noted here that the second T-shaped rod 501 guides the movement of the U-shaped push plate 401 after being subjected to force, and the fourth spring 502 facilitates the reset of the U-shaped push plate 401 after movement.

[0031] This solution describes an automatic sausage packaging machine, which includes the following steps: During the packaging process of sausages using an automatic packaging machine, the robotic arm 103, in conjunction with the clamping component, picks up the packaging bags and installs them onto the rotating table 102 in sequence. As the rotating table 102 rotates during the installation and placement of the packaging bags, the installed and fixed packaging bags pass through the feeding component and the pressure-reducing heat-sealing component 104 in sequence. The feeding component delivers the sausages into the packaging bags in multiple batches, and then the pressure-reducing heat-sealing component 104 performs pressure-reducing heat-sealing on the packaging bags to complete the packaging process of the sausages. During the process of installing and fixing the packaging bag onto the rotary table 102, the robotic arm component 103 grasps and moves the packaging bag. After grasping, the packaging bag is moved between the support plate 203 and the clamping plate 204 of the clamping assembly with the opening facing upwards. After moving, the clamping plate 204 retracts towards the support plate 203 through the driving action of the second cylinder 205. During the movement, the packaging bag is fixed between the support plate 203 and the clamping plate 204, completing the installation and fixing of the packaging bag on the rotary table 102. After the packaging bag is installed and fixed, the rotation of the rotary table 102 positions the packaging bag below the guide hopper 702. After the packaging bag has moved, it is lifted by the lifting assembly. Component 802 causes the U-shaped frame 801 to rise. This rising motion positions the two sets of positioning components on either side of the packaging bag. After the U-shaped frame 801 rises, the first cylinder 807 drives the moving plate 803 to move towards the outside of the packaging bag. During the movement of the moving plate 803, the telescopic components connect and move the mounting frame 804. As the mounting frame 804 moves, the ball bearings 806 on one side of each positioning plate 805 on the mounting frame 804 and the suction cover 1001 on one side of the mounting frame 804 abut against the outside of the packaging bag. The multiple sets of ball bearings 806 on the positioning plates 805 on both sides of the packaging bag then contact the outside of the packaging bag. The opposing squeezing action on both sides compresses and positions the packaging bag to be fed. After the suction hood 1001 abuts against the outer side of the packaging bag, the driving action of the suction pump 1003 and the connection action of the air pipe 1002 cause one side of the packaging bag to be adsorbed onto the suction hood 1001. After the ball bearings 806 and the suction hood 1001 abut against the outer side of the packaging bag, the opposing and limiting action between the ball bearings 806 on both sides of the packaging belt and the opposing and limiting action between the suction hoods 1001 and the suction hood 1001, causes the mounting brackets 804 on both sides of the packaging bag to be opposed and limited. With the continued movement of the moving plate 803, relative movement occurs between the moving plate 803 and the mounting brackets 804. During the relative movement, the L-shaped pull plate 1202 pulls the pull rope 1203, and the support roller 1204 supports it, pulling the connecting plate 1103 away from the fixed frame 1101. During the movement of the connecting plate 1103, the connecting rod 1102 pulls the pressure-collecting cover 1001 towards the fixed frame 1101, causing it to retract. Because the pressure-collecting cover 1001 adheres to and resists the outer side of the packaging bag, the movement of the pressure-collecting cover 1001 pulls the packaging bag. Through the movement of the two sets of pressure-collecting covers 1001 on opposite sides of the packaging bag, a circular feeding chamber is formed between the two sets of pressure-collecting covers on opposite sides of the packaging bag (see...). Figure 14The circular feeding cavity ensures sufficient space for the sausages to be fed into the packaging bag, allowing them to be quickly and stably fed into the bag. After the bag is pulled to form the feeding cavity, the sausages to be packaged are guided by the feeding holes 703 and fed into the feeding cavity. During the feeding process, two adjacent feeding cavities are separated by two positioning plates 805 to prevent the sausages from tilting and intersecting each other during the feeding process. After the sausage is fed into the container, the electromagnet 602 is energized. The magnetic force between the electromagnet 602 and the iron block 601 causes the two sets of L-shaped mounting seats 201 on the clamping assembly to move away from each other. Because the support plate 203 and clamping plate 204 on the L-shaped mounting seats 201 maintain the clamping and fixing effect on the packaging bag, the mutual movement of the two sets of L-shaped mounting seats 201 pulls the packaging bag to both sides after the sausage is fed into it. This pulling action eliminates the gap between the packaging bag and the sausage during the feeding process, ensuring that the inner side of the packaging bag fully adheres to and is compressed with the sausage, guaranteeing the safety of the packaging bag after feeding. The sausages are positioned to further prevent them from tilting or interlacing. During the movement of the L-shaped mounting base 201, it abuts against one side of the connecting rod 404. This abutment causes the connecting rod 404 to rotate around the mounting shaft 403. As the connecting rod 404 rotates, the interaction between the transmission groove 405 and the transmission pin 406 pushes the U-shaped push plate 401 towards the packaging bag. During this movement, the U-shaped push plate 401 pushes the sausages placed inside the packaging bag towards the center of the bag (see...). Figure 8 (In the state of packaging), the sausage inside the packaging bag is pushed to the center. By centering, the local wrinkles, bulges or uneven stress of the packaging bag caused by the sausage shifting are avoided, which improves the aesthetics and consistency of the product packaging and enhances the visual experience of consumers. After feeding and centering, the pressure pump 1003 is disconnected from the pressure chamber 1001. The pressure chamber 1001, positioning plate 805, mounting frame 804 and moving plate 803 are reset through transmission. After reset, the U-shaped frame 801 is driven to descend through the lifting component 802. The descent of the U-shaped frame 801 does not interfere with the subsequent movement of the packaging bag after feeding. Subsequently, the packaging bag after feeding and centering is moved to the side of the pressure-reducing heat-sealing component 104 by the rotation of the rotary table 102.
