[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1) The present invention first starts the work of the vibrating feeding device to output the tea cakes to the conveying device in a certain direction and at a certain interval, and then transports the tea cakes into the inner side of the frame through the conveying device. At this time, the feeding mechanism rises to receive the tea cakes. While receiving the tea cakes, the bag supply and bag opening mechanism synchronously grabs the packaging bags one by one to the bottom of the feeding mechanism and automatically completes the bag opening. At this time, the feeding mechanism reverses and descends to insert into the packaging bag, and pushes the tea cakes into the packaging bag to complete the entire feeding. Finally, the sealing mechanism heat-seals one end of the packaging bag to complete the packaging of the tea cakes.

[0025] 3) The present invention drives the material receiving chute to rise through the first driving source, providing enough space for the bag supply and opening mechanism to open the bag after conveying the bag to the designated position; then the first driving source reverses and moves the material receiving chute downward and inserts it into the opened packaging bag. At the same time, the conveying device starts to convey the tea cake to the material receiving chute. Due to the weight and the initial velocity of the tea cake, the tea cake slides along the material receiving chute and gets stuck at the bottom. At this time, the second driving source pushes the material pushing component to insert into the material receiving chute, pushing the tea cake into the packaging bag, completing one feeding of the tea cake. The above design can effectively reduce the space occupied by the equipment, thereby improving work efficiency and further improving the packaging efficiency of the tea cake.

[0033] Please refer to the attached drawings: a tea cake packaging machine includes a feeding mechanism 100, a frame 200, a vibrating feeding device 300, a conveying device 110, a bag supply and opening mechanism 400 and a sealing mechanism 500, wherein: the frame 200 can be generally made of metal materials such as steel, aluminum, etc., and is used to support the feeding mechanism 100, the conveying device 110, the bag supply and opening mechanism 400 and the sealing mechanism 500. The vibrating feeding device 300 is arranged on the left side of the frame 200, and the output end is connected to the conveying device 110, and is used to arrange the tea cakes according to a certain rule and then convey them to the conveying device 110. The conveying device 110 is arranged on the frame 200, and is used to carry and convey the tea cakes conveyed by the vibrating feeding device 300. The feeding mechanism 100 is arranged on the right side of the conveying device 110, and is used to cooperate with the conveying device 110 to put the tea cakes into the packaging bag. The bag supply and opening mechanism 400 is arranged on the frame 200, and is used to convey the packaging bags one by one to the bottom of the receiving chute 130 and open them. The sealing mechanism 500 is arranged on the frame 200, and is used to heat and seal the packaging bags. When the tea cake is pushed into the packaging bag by the feeding mechanism 100, the sealing mechanism 500 seals the packaging bag.

[0034] Wherein: when working, the vibration feeding device 300 starts working and outputs the tea cake to the conveying device 110 in a certain direction and at a certain interval, and the tea cake is transported into the inner side of the frame 200 by the conveying device 110. At this time, the feeding mechanism 100 rises to receive the tea cake. While receiving the tea cake, the bag supply and opening mechanism 400 synchronously grabs the packaging bags one by one to the bottom of the feeding mechanism 100 and automatically completes the bag opening. At this time, the feeding mechanism 100 moves in the opposite direction and descends to insert into the packaging bag, and pushes the tea cake into the packaging bag to complete the entire feeding. Finally, the sealing mechanism 500 heat-seals one end of the packaging bag to complete the packaging of the tea cake. By adopting the above technical solution, the present invention realizes a continuous process of automatic feeding, transitional receiving, bag opening, pushing and heat sealing of tea cakes in the entire packaging process, with a high degree of automation and a production efficiency of up to 2800 PCS / H. It effectively reduces labor costs and labor intensity, has low production costs, good product quality, high yield rate, and high equipment utilization. The feeding mechanism 100 , the conveying device 110 , the bag supplying and opening mechanism 400 , and the sealing mechanism 500 are described in detail below.

[0035] The feeding mechanism 100 includes a first driving source 120, a material receiving chute 130, a second driving source 140 and a material pushing component 150. Among them: the first driving source 120 is arranged on the frame 200 to provide power. In this embodiment, the first driving source 120 is a servo motor; the servo motor is installed on the frame 200 through a motor mounting plate. When working, the servo motor drives the synchronous belt to rotate, and then drives the material receiving chute 130 fixedly connected thereto to move up and down. A sensor is provided at the output end of the servo motor to sense the position of the material receiving chute 130. In this way, the use of a synchronous belt can achieve rapid response and improve efficiency. Of course, in other embodiments, the first driving source 120 can also be a cylinder or a connecting rod mechanism or a straight-moving mechanical structure. The material receiving chute 130 can be arranged on the right side of the conveying device 110 to receive the tea cakes conveyed by the conveying device 110. The first driving source 120 can drive the material receiving chute 130 to move back and forth in the vertical direction. The second driving source 140 is arranged on the frame 200 to provide power. The second driving source 140 is a servo motor. The servo motor is installed on the frame 200 through a motor mounting plate. When working, the servo motor drives the synchronous belt to rotate, and then drives the pusher component 150 fixedly connected thereto to move up and down. A sensor is provided at the output end of the servo motor to sense the position of the pusher component 150. In this way, the use of a synchronous belt can achieve a quick response and improve efficiency. Of course, in other embodiments, the second driving source 140 can also be a cylinder or a connecting rod mechanism or a straight-moving mechanical structure. The pusher component 150 can be slidably arranged on the frame 200, and the second driving source 140 can drive the pusher component 150 to move. When in use, the first driving source 120 drives the material receiving chute 130 to rise, providing enough space for the bag supply and opening mechanism 400 to open the bag after conveying the bag to the designated position; then the first driving source 120 reverses and moves the material receiving chute 130 downward to insert it into the opened packaging bag. At the same time, the conveying device 110 starts to convey the tea cake to the material receiving chute 130. Due to the weight and the initial velocity of the tea cake, the tea cake slides along the material receiving chute 130 and gets stuck at the bottom. At this time, the second driving source 140 moves to push the material pushing component 150 to insert into the material receiving chute 130, pushing the tea cake into the packaging bag, and completing the feeding of the tea cake. The above design can effectively reduce the space occupied by the equipment, thereby improving the work efficiency and further improving the packaging efficiency of the tea cake.

[0036] Based on the above embodiment, the material receiving chute 130 has a first slide arc surface 131 with a smooth surface and protective surfaces 132 connected to both sides of the first slide arc surface 131. As the conveying device 110 conveys the tea cake, the first driving source 120 drives the material receiving chute 130 to rise, so as to provide movement space for loading and opening the packaging bag; the material receiving chute 130 is driven to descend, so as to insert the material receiving chute 130 into the packaging bag, and the other end is connected to the end of the conveying device 110, so that the tea cake slides along the first slide arc to the bottom of the material receiving chute 130. At this time, the second driving source 140 drives the pushing component 150 to move downward to push the product into the packaging bag to complete the feeding action.

[0037] Based on the above embodiment: the receiving chute 130 further includes a connecting seat 133 and a tea cake inlet 134; the tea cake inlet 134 is arranged below the connecting seat 133 and connected to the end of the first slide arc surface 131 to form a receiving cavity for temporarily storing tea cakes. The first slide arc surface includes a circular arc surface and a vertical surface; the circular arc surface and the vertical surface have a smooth transition.

[0038] The bag supply and opening mechanism 400 includes a bag storage box 410, a third driving source 420, a flipping mechanism 430, a lifting cylinder 440 and a suction cup component 450; the third driving source 420 is arranged below the bag storage box 410; the output end of the third driving source 420 forms a transmission connection with the flipping mechanism 430; the lifting cylinder 440 is arranged at the output end of the flipping mechanism 430; the suction cup component 450 is arranged on the output push shaft of the lifting cylinder 440.

[0039] Specifically, when in use, the packaging bag is placed in the bag storage box 410. In this embodiment, the size of the bag storage box 410 can be adjusted according to the size of the packaging bag, so that it is more practical. After being placed, the suction cup component 450 is lifted up by the lifting cylinder 440 and sucks the packaging bag. Then, the third driving source 420 drives the flipping mechanism 430 to work and realizes the 90° flipping of the packaging bag. The whole process is simple, which can effectively shorten the bag supply and opening time and further improve the packaging efficiency. In addition, the bag supply and opening mechanism 400 of the present invention integrates multifunctional mechanical structures such as adsorption bag supply, bag opening, bag support, and import filling. It adopts a vacuum adsorption conveyor belt to supply the packaging bag, upper and lower vacuum adsorption bag opening, and import filling packaging process methods, so that the packaging bag can be transported in a dynamic state and maintain a good position and state, overcomes the wrinkles and movement on the packaging bag conveyor belt, and makes it difficult to cause the undesirable phenomenon of warping and bending when opening the bag. It has a novel design, a unique structure, a compact process, a wide adaptability of product packaging, good packaging quality, high production efficiency, and improves the automation of product packaging.

[0040] The sealing mechanism 500 includes a heat sealing box 510 for completing heat sealing, a heat sealing driving source 520, a heat sealing box closing power source 530 and a material dragging mechanism 540; the heat sealing driving source 520 is connected to the heat sealing box 510, and is used to drive the heat sealing knife inside the heat sealing box 510 to heat seal the packaging bag; the heat sealing box closing power source 530 is connected to the heat sealing box 510, and is used to drive the heat sealing box 510 to open and close; the material dragging mechanism 540 is arranged on the heat sealing box 510, and is used to drag the packaging bag to assist in heat sealing.

[0041] Among them: the heat sealing box 510 is a prior art and is well known to those skilled in the art, and will not be described in detail here. When working, the heat sealing box closing power source 530 pushes the heat sealing box 510 open, so that the packaging bag containing the tea cake enters the inner side of the heat sealing box 510, and at the same time the dragging mechanism 540 closes and drags the packaging bag from the bottom, and then the heat sealing driving source 520 and the heat sealing box closing power source 530 act at the same time to complete the heat sealing of the packaging bag, and then the heat sealing driving source 520 and the heat sealing box closing power source 530 act again to remove the heat seal and open the heat sealing box 510, and then the dragging mechanism 540 is opened again, and the heat-sealed packaging bag falls out of the heat sealing box 510. The whole process is simple to operate and does not require manual participation, thereby improving production efficiency. In addition, the sealing mechanism 500, the packaging bag falling guide device, the supporting mechanism and the fixed height mechanism are independent of each other but connected, so that the actions of each mechanism do not interfere with each other; the volume of the heat sealing box is reduced to a minimum, thereby improving work efficiency; the double-sided heat sealing mechanism adopts double-sided heating sealing technology to improve work efficiency, effectively reduce the large load of electrical components, and save energy; and each component adopts a humanized design, and the wearing parts adopt quick-disassembly and convenient installation components, so that users can use it more easily. The utility model adopts an outer bag falling guide device, a supporting mechanism, and a limiting mechanism to perform multi-directional positioning of the outer bag containing tea cakes, ensuring that the outer bag of tea cakes falling from the bag dropping port of the mainboard will not be skewed, thereby making the sealing more neat and more beautiful.

[0042] Based on the above embodiment, the material dragging mechanism 540 includes a driving cylinder 541 , a connecting rod mechanism 542 and a claw 543 ; the claw 543 is symmetrically and rotatably arranged on the connecting rod mechanism 542 ; and the output end of the driving cylinder 541 is connected to the connecting rod mechanism 542 .

[0043] Based on the above embodiment, the sealing mechanism 500 further includes a discharge tray 550 ; the discharge tray 550 is arranged on the heat sealing box 510 through fasteners.

[0044] In summary, the present invention first starts the work of the vibrating feeding device to output the tea cakes to the conveying device in a certain direction and at a certain interval, and then transports the tea cakes into the inner side of the frame through the conveying device. At this time, the feeding mechanism rises to receive the tea cakes. While receiving the tea cakes, the bag supply and bag opening mechanism synchronously grabs the packaging bags one by one to the bottom of the feeding mechanism and automatically completes the bag opening. At this time, the feeding mechanism reverses and descends to insert into the packaging bag, and pushes the tea cakes into the packaging bag to complete the entire feeding. Finally, one end of the packaging bag is heat-sealed by the sealing mechanism to complete the packaging of the tea cakes. By adopting the above technical scheme, the present invention realizes a continuous process of automatic feeding, transitional receiving, bag opening, pushing and heat sealing of tea cakes in the entire packaging process, with a high degree of automation and a production efficiency of up to 2800 PCS / H. It effectively reduces labor costs and labor intensity, has low production costs, good product quality, high yield rate, and high equipment utilization.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, the technicians can still modify or replace the specific implementation mode of the present invention with equivalents, but these modifications or changes do not deviate from the scope of protection of the pending claims of the present application.
