[0045] Example

[0046] Please refer to Figure 1-Figure 7 The utility model provides a tea bag packaging machine, including a mounting base 1, a winding roller 2, a folding belt structure 3, an annular guide plate 4, a rotating structure 5, a bag sealing and cutting structure 6, a material guide cylinder 7, a blocking structure 8, and a material storage box 9.

[0047] Furthermore, the belt roller 2 includes a main roller 201 and at least one auxiliary roller 202. The main roller 201 and the auxiliary roller 202 are both vertically rotatably arranged on the mounting base 1 and are used to roll up tea bags for packaging tea leaves to provide tea bags for the device.

[0048] The tea bag rolled out from the auxiliary roller 202 enters the folding belt structure 3, which mainly folds the single-layer tea bag into a double-layer tea bag to facilitate the subsequent loading of tea leaves.

[0049] The belt folding structure 3 includes a belt folding frame 301 , a guide frame 302 , a guide groove plate 303 , and a belt dividing plate 304 .

[0050] One end of the tea bag extends from the auxiliary roller 202 into the folding belt frame 301. The folding belt frame 301 is composed of a frame body fixed on the mounting base 1 and a curved groove on the top of the frame body.

[0051] The long groove of the bending groove is arranged horizontally. When the tea bag passes through the bending groove through the vertically arranged auxiliary roller 202, the upper and lower ends of the tea bag will be restricted by the long groove of the bending groove and bend from the middle of the tea bag, thereby folding the tea bag symmetrically into a double layer. At this time, the folded tea bag belt surface is in the horizontal direction, and the opening of the double-layer belt surface of the tea bag faces the horizontal direction.

[0052] In order to make the opening of the double-layer belt surface of the tea bag face upwards and facilitate the loading of tea leaves, a guide frame 302 is provided at the next station of the belt folding frame 301 for adjusting the direction of the folded tea bag belt surface.

[0053] The bent tea bag passes through the guide frame 302, which is composed of a frame fixed on the mounting base 1 and a guide groove on the frame. The long groove direction of the guide groove is set along the vertical direction. When the tea bag passes through the guide groove, the horizontal bag surface will be deflected ninety degrees by the guide groove, so that the bag surface of the tea bag is in the vertical direction. At this time, the opening of the double-layer belt surface of the tea bag faces upward, which is convenient for the introduction of tea leaves.

[0054] The tea bag with the adjusted angle then enters the groove of the guide groove plate 303 , which is used to maintain the double-folded state of the tea bag (to prevent the tea bag from unfolding again).

[0055] The guide groove plate 303 is an arc-shaped groove plate. The groove at one end of the guide groove plate 303 corresponds to the position of the winding roller 2 and the folding belt structure 3, and is responsible for introducing the folded tea bag. The groove at the other end of the guide groove plate 303 corresponds to the annular guide direction of the annular guide plate 4 due to its curved arc. There is a notch on the annular guide plate 4 to facilitate the other end of the guide groove plate 303 to extend into the notch, so that the notch of the guide groove plate 303 is connected to the annular guide groove of the annular guide plate 4.

[0056] The tea bag is guided into the subsequent annular guide plate 4 through the guide groove plate 303 , and the guide groove plate 303 is fixed on the mounting base plate 1 .

[0057] A strip dividing plate 304 is further provided in the middle of the groove of the guide groove plate 303. The strip dividing plate 304 is fixed to the top of the guide groove plate 303. The length direction of the strip dividing plate 304 is along the through-direction of the groove of the guide groove plate 303. It is responsible for separating the bent strip surfaces on both sides of the tea bag passing through the guide groove plate 303 from the middle part to avoid adhesion and affecting the subsequent feeding of tea leaves. The strip dividing plate 304 does not contact the bottom of the groove of the guide groove plate 303, and only separates the tea bag from the bent opening, without interfering with the normal guiding movement of the tea bag.

[0058] Furthermore, the tea bag enters the annular guide plate 4 through the guide groove plate 303 , and the annular guide plate 4 includes an annular groove plate 401 and a partition plate 402 .

[0059] A rotating structure 5 is provided at the axis of the annular groove plate 401 . The rotating structure 5 includes a first motor 501 , a connecting rod 502 , and a clamping cylinder 503 .

[0060] There is an annular guide groove in the annular groove plate 401 . The bottom of the annular groove plate 401 is through. A partition plate 402 is provided in the guide groove of the annular groove plate 401 . The partition plate 402 is located at the bottom of the annular groove plate 401 .

[0061] The first motor 501 is fixed on the mounting base 1 , and the driving shaft of the first motor 501 is located at the axis center of the annular groove plate 401 , and the driving shaft is connected to one end of the connecting rod 502 , and the other end of the connecting rod 502 is connected to the clamping cylinder 503 , and the clamping cylinder 503 is located in the guide groove of the annular groove plate 401 .

[0062] Preferably, when packaging tea bags, the clamping claws of the clamping cylinder 503 clamp the end of the tea bag extending from the folding belt structure 3, and then rotate through the first motor 501, driving the clamped tea bag into the annular guide groove of the annular groove plate 401 through circular motion, which is convenient for subsequent bag sealing work.

[0063] Furthermore, a material guide barrel 7 is provided above the annular guide plate 4, in which tea leaves are stored. The shape of the outlet of the material guide barrel 7 matches the shape of the annular guide plate 4 below it, so that the tea leaves enter the bent tea bag in the annular guide plate 4 below through the outlet.

[0064] A bag cutting structure 6 is further provided on the inner side of the annular guide plate 4 . The bag cutting structure 6 includes a driving member, a slide plate 604 , a sealing plate 605 , a chute plate 606 and a cutter 610 .

[0065] Among them, the slide plate 606 is set at the axis center of the annular guide plate 4, and multiple slide grooves are evenly arranged on the slide plate 606. The slide grooves are arranged around the axis center of the annular guide plate 4. Each slide groove is correspondingly provided with a slide plate 604. A driving part is provided at one end of the slide plate 604 facing the axis center of the annular guide plate 4, and a sealing plate 605 is provided at the other end of the slide plate 604.

[0066] The top surface of the inner plate of the annular groove plate 401 is slidably connected to the bottom surface of the sealing plate 605 , and the outer surface of the sealing plate 605 abuts against the outer plate surface of the annular groove plate 401 .

[0067] Preferably, when sealing the tea bag, the driving member drives the slide plate 604 to slide, and the sealing plate 605 at one end of the slide plate 604 extends into the annular groove plate 401, abuts against the outer plate surface of the annular groove plate 401, and flattens and seals the top opening of the tea bag.

[0068] Vertical pressure plates 609 are provided at both ends of the bottom surface of the sealing plate 605, each corresponding to a partition 402 in the annular guide plate 4. Vertical slots are formed through the inner side of the annular groove plate 401 at positions corresponding to the partitions 402. The vertical pressure plates 609 follow the sealing plate 605 through the vertical slots and press into the annular groove plate 401, flattening and sealing the vertical ends of the tea bag.

[0069] By pressing the sealing plate 605 and the vertical pressing plate 609 , the entire tea bag in the shape of a ring in the annular groove plate 401 is sealed into individual tea bag spaces.

[0070] A cutter 610 is also provided at the outermost side of the vertical pressing plate 609. When the tea bag is flattened and sealed, the cutter 610 is used to vertically cut the individual tea bag spaces into individual tea bags by squeezing force. Multiple tea bags can be produced at one time by circumferentially arranged cutters 610.

[0071] It is worth noting that the sealing plate 605 and the vertical pressing plate 609 are both heat-conducting structures, and a heater (not shown in the figure) is fixed thereon to heat them so as to facilitate the airtight sealing of the tea bag.

[0072] Furthermore, the tea bag falls from the through-hole at the bottom of the annular groove plate 401 into the storage box 9 below. The storage box 9 is fixed below the mounting base 1 . The storage box 9 includes a finished product box 901 and a draw plate 902 .

[0073] There is a feeding opening on the top surface of the finished product material box 901 and the installation base plate 1. The shape of the feeding opening matches the bottom surface projection shape of the annular guide plate 4, which is convenient for the produced tea bags to fall directly into the finished product material box 901 for storage. A drawer 902 is slidingly provided in the finished product material box 901. When the external staff pulls out the drawer 902, the tea bags in the finished product material box 901 can be taken out.

[0074] In this embodiment, a sealing structure 8 is also included, which is used to periodically seal the tea leaves in the guide barrel 7 and the tea bags in the annular guide plate 4. The sealing structure 8 includes a bottom cylinder 801, a bottom sealing plate 802, a top cylinder 803, a top sealing plate 804, and a support seat 805.

[0075] Specifically, the bottom sealing plate 802 is slidably connected to the bottom surface of the annular guide plate 4 , and the bottom sealing plate 802 matches the bottom projection shape of the annular guide plate 4 .

[0076] The top sealing plate 804 is slidably connected to the outlet surface of the material guiding cylinder 7 , and the top sealing plate 804 matches the projection shape of the outlet of the material guiding cylinder 7 .

[0077] The push rod of the top cylinder 803 is fixedly connected to the top sealing plate 804 , and the push rod of the bottom cylinder 801 is fixedly connected to the bottom sealing plate 802 . Both the top cylinder 803 and the bottom cylinder 801 are fixedly set on the support seat 805 .

[0078] The blocking structure 8 is symmetrically arranged at both ends of the annular guide plate 4 to avoid the annular guide plate 4, the folding belt structure 3 and the guide barrel 7 from the support end of the mounting base 1. The top sealing plate 804 and the bottom sealing plate 802 in the blocking structure 8 are arc-shaped.

[0079] In this embodiment, the driving member includes a gear plate 601 , an arc-shaped slot 602 , a sliding post 603 , a gear 607 , and a second motor 608 .

[0080] Specifically, the gear plate 601 is coaxial with the drive shaft of the first motor 501, and the gear plate 601 is rotatably set on the drive shaft of the first motor 501. The gear plate 601 is meshed with the gear 607, and the gear 607 is fixed on the drive shaft of the second motor 608. The second motor 608 is fixed on the mounting base 1.

[0081] A plurality of arcuate slots 602 are evenly arranged on the gear plate 601 . The arcuate slots 602 are arranged around the axis of the first motor 501 . A sliding post 603 is slidably disposed in each arcuate slot 602 . The sliding post 603 is fixed on a slide plate 604 .

[0082] The gear plate 601 is driven to rotate by the second motor 608, and the arc groove 602 on the gear plate 601 also rotates. The arc groove 602 applies a force to the slide column 603, causing the slide plate 604 connected to the slide column 603 to slide in the slide plate 606, thereby extending into the annular groove plate 401 to perform the bag sealing function.
