Description

Technical Field

[0001] This application belongs to the field of machinery, apparatus or equipment for packaging objects or materials, and particularly relates to a packaging bag machine for powdered phenolic resin. Background Technology

[0002] Powdered phenolic resin is a 200-300 mesh powder formed by pulverizing flaky or granular phenolic resin. It is stored in a dedicated phenolic resin storage tank. During the production process, the powdered phenolic resin does not leak into the workshop due to the sealed equipment. However, during the packaging process, the powdered phenolic resin flows out along the discharge pipe. Since there is no seal between the discharge pipe and the packaging bag, a large flow of powdered phenolic resin from the discharge pipe causes leakage between the discharge pipe and the packaging bag. Due to its powdery nature, powdered phenolic resin causes serious dust pollution in the packaging workshop.

[0003] In addition, when packaging powdered phenolic resin, it is necessary to first sort the packaging bags, fill them into bags, and then transfer the filled packaging bags. The efficiency of a single transport vehicle carrying packaging bags is low when transferring these bags between these workstations. Utility Model Content

[0004] In order to solve the above problems, this application provides a powdered phenolic resin packaging bag machine.

[0005] The purpose of this application is to provide a packaging machine for powdered phenolic resin, which uses a bag sealing device to seal the bag opening and the discharge pipe, and uses at least two packaging bag carriers to improve packaging efficiency.

[0006] To achieve the purpose of this application, the technical solution of this application is as follows:

[0007] A powdered phenolic resin packaging bag making machine includes at least two packaging bag carriers connected together by a connector. The packaging bag carriers move along a track. A bag opening sealing device is provided on the discharge pipe of the powdered phenolic resin. The bag opening sealing device includes a clamping plate fixed on the discharge pipe, a connecting plate on the clamping plate, a locking plate at the lower end of the connecting plate, and an air bladder on the inner circumference of the locking plate. The air bladder is connected to an air intake and extraction device through a venting connector.

[0008] Furthermore, the clamping plate includes two pieces, which are connected together by bolts so that the clamping plate and the discharge pipe are interference fit. Each clamping plate is provided with a connecting plate, which is hinged to the clamping plate. The locking plate includes two pieces, and a locking plate is provided at the lower end of each connecting plate. Each locking plate has an air bladder on its inner circumference.

[0009] Furthermore, one locking plate has an insert plate at one end with a notch, and another locking plate has a slot at one end that mates with the insert plate. The third locking plate has a locking pin, which includes a locking pin and a return spring supporting the locking pin. The insert plate is inserted into the slot, and under the action of the return spring, the locking pin is inserted into the notch of the insert plate.

[0010] Furthermore, each card plate is equipped with a fixing plate, and the fixing plate is equipped with a tension spring, the other end of which is connected to the connecting plate.

[0011] Furthermore, the fixing plate is provided with multiple through holes, and one end of the tension spring is arranged in different through holes so that the tension spring generates different tensions.

[0012] Furthermore, the packaging bag carrier includes a base plate, on which a guardrail is installed, and on the guardrail are opening and closing doors.

[0013] Furthermore, the connector includes a bottom connecting plate for connecting the base plate and a connecting bracket for connecting the guardrail.

[0014] Furthermore, positioning posts are installed on the track to fix a packaging bag carrier vehicle on the track.

[0015] Furthermore, the positioning post includes a connecting stud, with a hexagonal end at the upper end of the connecting stud, a central sleeve at the hexagonal end, a compression spring inside the central sleeve, and a movable column around the outer periphery of the central sleeve. One end of the compression spring is connected to the central sleeve or the hexagonal end, and the other end of the compression spring is connected to the movable column. A lower wing plate is provided at the lower end of the movable column, an upper wing plate is provided at the upper end of the central sleeve, and a buffer pad is provided at the lower end of the upper wing plate.

[0016] Furthermore, each packaging bag carrier is equipped with a pull rod, which is connected to a pulling device.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] 1. This application utilizes a bag-sealing device to lock and seal the connection between the bag opening and the discharge pipe. When powdered phenolic resin is conveyed into the bag along the discharge pipe, the air bladder of the locking plate squeezes the bag opening against the discharge pipe, preventing the powdered phenolic resin from leaking out from the connection between the bag opening and the discharge pipe, reducing the amount of dust in the packaging workshop, and also avoiding the impact of powdered phenolic resin on the bagging personnel.

[0019] 2. The bag sealing device of this application has an insert plate on one of its locking plates. After the insert plate is inserted into the slot, the locking pin fixes the insert plate in the slot. The insert plate can only be disengaged from the slot by lifting the locking pin, thus avoiding the phenomenon of the two locking plates suddenly separating due to accidental contact.

[0020] 3. This application uses at least two packaging bag carriers. The packaging bags can be placed in the packaging bag carriers. Each time, the packaging bags in one packaging bag carrier will cooperate with the discharge pipe to complete the filling. The other packaging bag carrier can perform the operation of placing packaging bags or transferring the packaging bags that have been filled, which improves efficiency. The positioning column on the track will fix the position of the packaging bag carrier, so that the packaging bag carrier can perform the filling and other operations in a fixed position.

[0035] Example 1

[0036] This embodiment is a bagging machine for powdered phenolic resin, located in the packaging workshop. It is used for bagging powdered phenolic resin and is a bagging machine for powdered phenolic resin. Powdered phenolic resin is a 200-300 mesh powder material formed by crushing flaky or granular phenolic resin into powder after being crushed by a pulverizer. It is generally stored in a special phenolic resin storage tank. The storage tank has a discharge pipe 10 with a control valve. When the control valve is opened, the powdered phenolic resin flows out along the discharge pipe 10. At this time, the powdered phenolic resin is carried in a packaging bag, sewn, packaged, and transferred to complete the shipment of the powdered phenolic resin.

[0037] Currently, due to its powdery nature, powdered phenolic resin causes severe dust pollution in packaging workshops. There is no seal between the discharge pipe 10 and the packaging bag, and a large flow of powdered phenolic resin flows out from the discharge pipe 10, causing leakage of phenolic resin between the discharge pipe 10 and the packaging bag. This embodiment focuses on solving this problem.

[0038] In this embodiment, a bag sealing device is installed on the discharge pipe 10 of powdered phenolic resin. The bag sealing device includes a clamping plate 1 fixed on the discharge pipe 10, a connecting plate 2 installed on the clamping plate 1, a locking plate 3 at the lower end of the connecting plate 2, and an airbag 4 on the inner circumference of the locking plate 3. The airbag 4 is connected to the air intake and exhaust device through an air connector 5 and a flexible air supply pipe. The switch for controlling the inflation or deflation of the airbag 4 is installed on a bracket next to the workstation.

[0039] As one implementation scheme, the card plate 1 is a single piece. The card plate 1 is fitted around the outer periphery of the discharge pipe 10 and fixedly connected to the discharge pipe 10 with bolts. The airbag 4 on the locking plate 3 is a single piece. When in use, the packaging bag is placed between the locking plate 3 and the discharge pipe 10. However, this scheme is relatively troublesome, especially when the packaging bag is in use, it is inconvenient to put the bag on and takes a long time.

[0040] In another implementation, the bag sealing device of this embodiment is divided into two parts. The clamping plate 1 includes two pieces, which are bolted together to form an annular plate. The bolts bring the clamping plates 1 close together, thus ensuring an interference fit between the clamping plates 1 and the discharge pipe 10, allowing the bag sealing device to be fixed to the discharge pipe 10. Each clamping plate 1 is equipped with a connecting plate 2, which is hinged to the clamping plate 1. Specifically, the clamping plate 1 has a hinge seat, and the connecting plate 2 is hinged to the hinge seat via a hinge shaft, enabling the connecting plate 2 to... It can move within a certain range. The locking plate 3 includes two pieces. Each connecting plate 2 has a locking plate 3 at its lower end. The locking plate 3 is fixedly connected to the connecting plate 2. Each locking plate 3 has an airbag 4 arranged on its inner circumference. Ribs are arranged on the clamping plate 1 and the locking plate 3 to enhance the structural strength of both. When it is necessary to install the packaging bag, the two locking plates 3 are separated, the bag opening of the packaging bag is put on the outside of the discharge pipe 10, and then the two locking plates 3 are joined together. The airbag 4 is inflated so that the airbag 4 squeezes the bag opening of the packaging bag and the discharge pipe 10 together.

[0041] Specifically, in this embodiment, an insert plate 7 is installed at the end of one locking plate 3, referred to as the first locking plate 3. The insert plate 7 has a notch. A slot is provided at the end of another locking plate 3 to mate with the insert plate 7. A locking pin 6 is installed on the other locking plate 3, referred to as the second locking plate 3. The locking pin 6 includes a locking pin and a return spring supporting the locking pin. When the insert plate 7 is inserted into the slot, the insert plate 7 compresses the locking pin, causing the return spring to deform. When the locking pin is inserted into the notch of the insert plate 7, in… Under the pulling action of the return spring, the locking pin is inserted into the notch of the insert plate 7 and no longer moves, so that the two locking plates 3 are joined together. When the two locking plates 3 need to be separated, the locking pin is pulled, so that the return spring is stretched, the locking pin is separated from the insert plate 7, and the two locking plates 3 can be separated. This embodiment adopts the method of pulling out the locking pin to avoid the use of the pressing method. The insert plate 7 can only be disengaged from the slot by lifting the locking pin, which avoids the phenomenon of the two locking plates 3 suddenly separating due to accidental contact.

[0042] As a more specific implementation, this embodiment has a fixing plate 8 installed on each card plate 1. For example, the fixing plate 8 can be fixed to the outside of the hinge seat of the card plate 1 by bolts. A tension spring 9 is installed on the fixing plate 8, and the other end of the tension spring 9 is connected to the connecting plate 2. When the two locking plates 3 are separated, under the action of the tension spring 9, after the locking pin is pulled out, the two locking plates 3 will immediately separate. The operator only needs to pull out the locking pin and does not need to manually separate the locking plates 3. After pulling out the locking pin, the bag opening can be tied immediately, and the packaged bag can be transferred by the packaging bag carrier. As a further implementation, this embodiment can open multiple through holes on the fixing plate 8, and one end of the tension spring 9 is arranged in different through holes so that the tension spring 9 forms different tensions, thereby adjusting the magnitude of the force when the two locking plates 3 are separated.

[0043] This embodiment utilizes packaging bag carriers to carry packaging bags. There are at least two packaging bag carriers; for example, this embodiment has a first carrier 12 and a second carrier 13. This allows one carrier to handle bagging while the other handles placing or transferring packaging bags. The packaging bag carriers are connected together via connector 14. Specifically, each packaging bag carrier includes a base plate with a guardrail. An opening / closing door is installed on the guardrail and is hinged to the guardrail. The base plate, guardrail, and opening / closing door are all constructed using square steel tubing to form an integrated frame structure. Connector 14 includes a bottom connecting plate connecting the base plate and a connecting bracket connecting the guardrail. This bottom and middle connection allows the two packaging bag carriers to be stably connected. Each packaging bag carrier is equipped with a pull rod. The rod is connected to a pulling device, such as a winch that pulls the packaging bag carrier by pulling a rope. Alternatively, in this embodiment, a drive device can be installed on the wheels of the packaging bag carrier to move the packaging bag carrier. When the packaging bag carrier is in the middle position (i.e., the second carrier 13 is in the middle position) and the other packaging bag carrier is in the left position (i.e., the first carrier 12 is in the left position), the packaging bag carrier in the left position can perform operations such as placing packaging bags. When one packaging bag carrier is in the middle position (i.e., the first carrier 12 is in the middle position) and the other packaging bag carrier is in the right position (i.e., the second carrier 13 is in the right position), the packaging bag carrier in the right position can perform operations such as transferring packaging bags, while the packaging bag carrier in the middle position can perform operations such as filling bags or placing and then filling bags.

[0044] In this embodiment, the packaging bag carrier moves along track 11, which is laid on the ground. Specifically, as a positioning structure, this embodiment positions and limits the wheels of the packaging bag carrier. A positioning post 15 is installed on track 11, which fixes the packaging bag carrier to track 11. In a more specific implementation, the positioning post 15 includes a connecting stud 16, the upper end of which has a hexagonal end 17. The hexagonal end 17 can be rotated using a wrench or the like, thereby connecting the connecting stud 16 to the corresponding structural component. The hexagonal end 17 has a central sleeve 19, inside which is a compression spring 20. The outer periphery of the central sleeve 19 has a movable column 18. One end of the compression spring 20 is connected to the central sleeve 19 or the hexagonal end 17, compressing... The other end of the spring 20 is connected to the movable column 18. The movable column 18 consists of two parts, which are connected as a whole by bolts. The lower end of the movable column 18 has a lower wing plate 22, and the upper end of the central sleeve 19 has an upper wing plate 21. The lower wing plate 22 moves between the hexagonal end 17 and the upper wing plate 21. The lower end of the upper wing plate 21 has a buffer pad 23 to prevent the upper wing plate 21 from rigidly contacting the lower wing plate 22. When the wheel passes the positioning post 15, the wheel squeezes the movable column 18, which in turn compresses the compression spring 20. After the wheel passes the positioning post 15, the movable column 18 returns to its original position under the action of the compression spring 20, thus blocking the wheel. Therefore, in this embodiment, the positioning posts 15 are arranged in pairs, blocking the wheels on both sides of the two wheels to achieve the positioning of the packaging bag carrier vehicle.
