Description

Technical Field

[0001] This utility model relates to the field of tea packaging technology, specifically to an anti-clogging feeding device. Background Technology

[0002] Triangular packaging machines are automated precision equipment that can seal green tea, black tea, flower tea, coffee, health tea, herbal tea, and granules in triangular bags. They are suitable for packaging in the food and pharmaceutical industries. Among these, the vertical bag forming-filling-sealing machine is the most widely used packaging machinery. Its principle is that the material to be packaged passes through the forming cylinder, and the bag forming and filling proceed vertically from top to bottom. The packaging material wraps around the outer surface of the forming cylinder and is gradually rolled into a cylindrical shape from top to bottom. It is then heat-sealed by a longitudinal heat sealer to obtain a sealed tube, and then moved to a lower transverse heat sealer for horizontal sealing. This type of packaging machinery is widely used in the packaging production of tea bags.

[0003] A search revealed Chinese patent application number "CN201720227482.3", which discloses a triangular packaging machine. By setting a support frame that can rotate around an axis, and a first slide rail on the support frame, the sealing assembly is movable. The ultrasonic welding gun of the sealing assembly is fixed to the connecting plate, and the cutter head is mounted on the connecting plate through a cutter head driving device.

[0004] In the process of implementing this utility model, the inventors discovered the following problems with the existing technology:

[0005] In the packaging process, existing technology continuously feeds materials into the forming machine through a feeding mechanism. The material at the bottom enters the rolled-up packaging material from the bottom of the forming machine and is then heat-sealed by a heat sealer. However, other materials accumulate in the forming machine, which can easily cause blockages. As a result, workers need to constantly observe and clear the remaining material accumulated in the forming machine, increasing their workload.

[0006] Therefore, the present invention urgently needs to solve the problem of providing an anti-blocking feeding device that can clear the material inside the molding machine through an anti-blocking mechanism during use, avoids the need for manual clearing of the material inside the molding machine during the packaging process, and has a simple structure, small size, and reduced use and maintenance costs. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the shortcomings of existing technologies where the feeding mechanism continuously feeds materials into the forming device. The bottom portion of the material enters the rolled-up packaging material from the bottom of the forming device and is then heat-sealed by a heat sealer, while other materials accumulate inside the forming device, potentially causing blockages. This necessitates constant monitoring by staff to clear any remaining material, increasing their workload. Therefore, this invention provides an anti-blocking feeding device that uses an anti-blocking mechanism to clear material from the forming device during use. This prevents blockages during packaging, avoiding the need for manual clearing. Furthermore, the anti-blocking mechanism is simple in structure, small in size, and reduces operating and maintenance costs.

[0008] To achieve the above objectives, this utility model provides an anti-clogging feeding device, which includes: a bracket fixed on the frame, a feeding hopper forming device, and an anti-clogging mechanism;

[0009] The molding device is vertically fixed on the support. A feed hopper is vertically fixed on the support next to the molding device. The discharge end of the feed hopper is connected to the molding device. The anti-blocking mechanism includes a vibrator and a guide rod.

[0010] A vibrator is fixedly installed on the top of the bracket located next to the molding machine. At least one guide rod is fixedly installed on the vibrator, which can extend into the molded machine from the slot on the top of the molding machine and drive it to vibrate.

[0011] Preferably, the bottom end of the guide rod is provided with a plurality of feeding components at equal intervals and at an incline along its circumference.

[0012] Preferably, the feed hopper is connected to the discharge end of the feeding mechanism.

[0013] Preferably, the forming device comprises, from top to bottom, an inclined portion and a tubular portion; wherein,

[0014] The bottom end of the inclined portion is connected and fixed together with the tubular portion, and the diameter of the groove of the inclined portion gradually decreases from top to bottom. The discharge end of the bottom of the feed hopper extends from the top opening of the tubular portion into its interior and communicates with its interior.

[0015] Preferably, the device further includes a guiding mechanism to allow the packaging material unwound from the unwinding mechanism to descend from above the forming device and wrap around its outer surface; the guiding mechanism includes a first guide roller and a second guide roller; wherein,

[0016] On the frame located above the forming machine, there are two guide rollers, a first guide roller and a second guide roller, spaced apart and horizontally and rotatably arranged to guide the packaging material as it passes between them.

[0017] Preferably, at least one conveyor roller is horizontally and rotatably arranged on the frame between the unwinding mechanism and the guiding mechanism.

[0018] Preferably, the conveying roller and the first guide roller are respectively provided with C-shaped limiting members that are spaced apart and coaxially snapped together.

[0019] According to the above technical solution, the beneficial effects of the anti-clogging feeding device provided by this utility model in use are as follows:

[0020] (1) In use, the material enters the interior of the forming device through the feed hopper, while the packaging material wraps around the outer surface of the forming device from top to bottom and is gradually rolled into a cylindrical shape. It is then heat-sealed by a longitudinal heat sealer to obtain a sealed tube. The material falls from the bottom of the forming device into the packaging material inside the sealed tube, and then moves to the lower transverse heat sealer for transverse sealing, thus completing the material packaging process. During the packaging process, a vibrator drives the guide rod to vibrate inside the forming device to prevent blockage of the material entering the forming device, avoiding the need for constant observation by staff to clear any remaining material accumulated inside the forming device. This saves time and effort and improves work efficiency.

[0021] (2) The anti-blocking mechanism consisting of the vibrator and the guide rod is small in size and low in cost, which reduces the cost of use and maintenance.

[0022] In summary, this utility model can clear the material inside the molding machine through the anti-blocking mechanism, avoiding blockages inside the molding machine during the packaging process that would require manual clearing by staff. Moreover, the anti-blocking mechanism has a simple structure and small size, reducing the cost of use and maintenance.

[0023] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] Example 1:

[0034] like Figures 1-4 As shown, the present invention provides an anti-clogging feeding device, which includes: a bracket 1 fixed on the frame, a feeding hopper 2, a forming device 3, and an anti-clogging mechanism;

[0035] The molding device 3 is vertically fixed on the support 1. A feed hopper 2 is vertically fixed on the support 1 next to the molding device 3. The discharge end of the feed hopper 2 is connected to the molding device 3. The anti-blocking mechanism includes a vibrator 4 and a guide rod 5.

[0036] A vibrator 4 is fixedly installed on the top of the support 1 located next to the molding machine 3. At least one guide rod 5 is fixedly installed on the vibrator 4, which can extend into the interior of the molding machine 3 from the slot on the top and drive it to vibrate.

[0037] In the above scheme, during use, the material enters the interior of the forming device 3 through the feed hopper 2. The packaging material wraps around the outer surface of the forming device 3 from top to bottom and is gradually rolled into a cylindrical shape. It is then heat-sealed by a longitudinal heat sealer to obtain a sealed tube. The material falls from the bottom of the forming device 3 into the packaging material inside the sealed tube, and then moves to the lower transverse heat sealer for transverse sealing, completing the material packaging process. During the packaging process, the vibrator 4 drives the guide rod 5 to vibrate inside the forming device 3 to prevent blockage of the material entering the forming device 3. This eliminates the need for workers to constantly observe and clear any remaining material accumulated in the forming device. This saves time and labor, improving work efficiency.

[0038] In addition, the anti-blocking mechanism composed of the vibrator 4 and the guide rod 5 is small in size and low in cost, which reduces the cost of use and maintenance.

[0039] Furthermore, this embodiment does not modify the molding device 3 and uses existing technology. Since the molding device 3 is common technical knowledge in the current field, its specific operating principle will not be described in detail here.

[0040] In a preferred embodiment of this utility model, the feed hopper 2 is connected to the discharge end of the feeding mechanism.

[0041] In the above scheme, the material enters the molding machine 3 through the feed hopper 2 via a feeding mechanism disclosed in the prior art.

[0042] In a preferred embodiment of this utility model, the forming device 3 comprises, from top to bottom: an inclined portion 301 and a tubular portion 302; wherein,

[0043] The bottom end of the inclined portion 301 is connected and fixed together with the tubular portion 302, and the diameter of the groove of the inclined portion 301 gradually decreases from top to bottom. The discharge end of the bottom of the feed hopper 2 extends from the top opening of the tubular portion 302 into its interior and communicates with its interior.

[0044] In the above scheme, when in use, the packaging material is included on the forming device 3, which consists of the inclined part 301 and the tubular part 302, whose groove diameter gradually decreases from top to bottom, so that the packaging material is gradually rolled into a cylindrical shape from top to bottom to hold the material and to package the material.

[0045] In a preferred embodiment of this utility model, the device further includes a guiding mechanism to allow the packaging material unwound from the unwinding mechanism to descend from above the forming device 3 and wrap around the outer surface of the forming device 3. The guiding mechanism includes a first guide roller 6 and a second guide roller 7.

[0046] On the frame above the forming machine 3, there are a first guide roller 6 and a second guide roller 7 spaced apart, horizontally and rotatably arranged to guide the packaging material as it passes between them.

[0047] In the above scheme, when in use, the packaging material wound on the unwinding mechanism in the prior art can pass between the first guide roller 6 and the second guide roller 7 located above the forming device 3 and wrap around the forming device 3 from top to bottom, so that the packaging material wrapped around the forming device 3 is gradually rolled into a cylindrical shape from top to bottom to hold the material discharged from the bottom of the forming device 3, thereby facilitating the packaging of the material.

[0048] In a preferred embodiment of this utility model, at least one conveyor roller 8 is horizontally and rotatably arranged on the frame between the unwinding mechanism and the guiding mechanism.

[0049] In a preferred embodiment of this utility model, C-shaped limiting members 9 are respectively and coaxially fixedly arranged on the shafts of the conveying roller 8 and the first guide roller 6.

[0050] In the above scheme, the distance between the two limiting members 9 on the conveying roller 8 or the first guide roller 6 is equal to the width of the packaging material, so as to limit the packaging material and prevent the packaging material from shifting after passing through the conveying roller 8 and the first guide roller 6 during the packaging process, thus affecting the packaging effect.

[0051] In addition, the spacing of the notches on the limiting member 9 is smaller than the diameter of the first guide roller 6 or the conveying roller 8, so that each limiting member 9 can tightly hold the first guide roller 6 or the conveying roller 8. The limiting member 9 has notches to make it C-shaped, so as to facilitate its assembly on the first guide roller 6 and the conveying roller 8.

[0052] Example 2

[0053] like Figures 1-5 As shown, the difference between Example 2 and Example 1 is that:

[0054] In a preferred embodiment of this utility model, the bottom end of the guide rod 5 is provided with a plurality of material feeding components 10 at equal intervals and at an incline along its circumference.

[0055] In the above scheme, the guide rod 5 extends from the opening at the top of the forming device 3 into the interior of its tubular portion 302, and several unblocking components 10 are fixedly and inclined at equal intervals along its circumference at the bottom of the guide rod 5 located inside the tubular portion 302. The bottom end of each unblocking component 10 has a certain gap with the inner wall of the tubular portion 302, the gap ranging from 1 to 2 cm.

[0056] In use, the vibrator 4 drives the guide rod 5 and all the unblocking parts 10 to vibrate. In addition, by setting multiple unblocking parts 10, more contact with the material can be achieved, which can better drive the material to vibrate, so as to facilitate the material to be discharged from the pipe opening at the bottom of the tubular part 302 of the forming device 3.

[0057] The rest of Example 2 is the same as Example 1.

[0058] In summary, the anti-clogging feeding device provided by this utility model overcomes the problem that in the prior art, the feeding mechanism continuously conveys materials into the forming device, and the material at the bottom enters the rolled-up packaging material from the bottom of the forming device and is heat-sealed by the heat sealer, while other materials accumulate in the forming device, which may easily cause blockage. This requires the staff to constantly observe and clear the remaining material accumulated in the forming device, which increases the workload of the staff.

[0059] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0061] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
