Description

Technical Field

[0001] The utility model relates to the technical field of paper carrier tape preparation, in particular to a punched paper tape scrap recovery device. Background Art

[0002] Paper carrier tapes are made by cutting base paper into long strips, and then using a punching device to punch the strips at equal intervals to generate square storage holes for carrying electronic components and traction holes for traction. Depending on whether the storage holes of the paper carrier tape are through holes, paper carrier tapes are divided into punched paper tapes (storage holes are not through) and perforated paper tapes (storage holes are through). When making perforated paper tapes, the problem of recycling paper scraps at the bottom of the through storage holes is involved.

[0003] To solve the above problems, Chinese patent application number 201520621436.2 discloses a centralized paper scrap processing device for punching electronic paper tapes. The centralized paper scrap processing device disclosed above includes a paper scrap discharge pipe, an induced draft fan and a water film dust collector. One end of a plurality of paper scrap discharge pipes is respectively connected to the paper scrap discharge port of each punching device, and the other end is respectively connected one-to-one with a plurality of interfaces provided on a centralized paper scrap recovery pipe. The centralized paper scrap recovery pipe is connected to a receiving hopper, and the air outlet of the receiving hopper is connected to the air inlet of the induced draft fan through the fan inlet pipe, and the outlet of the induced draft fan is connected to the inlet of the water film dust collector through the outlet pipe.

However, the above-mentioned recycling and processing device needs to work continuously for 24 hours when in use, which consumes a lot of energy, and all the punching devices are in series. If individual equipment fails and is shut down for maintenance, the recycling and processing device needs to be shut down, resulting in the inability to continue to recycle the paper scraps of all the punching devices. The paper scraps are blocked at the discharge port, affecting the preparation of the punched paper tape. Utility Model Content

[0006] In order to achieve the purpose of the above-mentioned utility model, the utility model adopts the following technical scheme: a paper scrap recovery device for a punched paper tape, comprising a temporary storage mechanism for temporarily storing paper scraps and a negative pressure collection mechanism connected to the temporary storage mechanism for conveying paper scraps, the temporary storage mechanism and the negative pressure collection mechanism are connected by a pipeline; the pipeline comprises a branch pipeline and a plurality of collecting tubes connected to the branch pipeline, the temporary storage mechanism comprises a plurality of storage tanks for temporarily storing paper scraps, and a plurality of the storage tanks are connected one by one with a plurality of the collecting tubes; a first valve for controlling the switch of the collecting tube is provided on the plurality of the collecting tubes, and a second valve for controlling the switch of the branch tube is provided on the branch pipeline; the negative pressure collection mechanism comprises a high-pressure fan for providing conveying power, and a recovery bin for recovering paper scraps is connected to the high-pressure fan.

[0007] The temporary storage mechanism can temporarily store paper scraps in several storage tanks, so that the paper scrap recovery device does not need to be opened 24 hours a day to save energy. In addition, the first valve and the second valve can be opened and closed manually or automatically. When a certain punching device fails and needs to be repaired, the paper scraps of other punching devices can be temporarily stored in the corresponding storage tank. At the same time, the first valve on the collection pipe corresponding to the storage tank can be closed separately and the second valve can be opened to complete the paper scrap recovery of other punching devices.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The paper scraps can be temporarily stored through several storage tanks in the temporary storage mechanism, so that the paper scrap recovery device does not need to be opened 24 hours a day, thereby saving energy. When a certain punching device fails and needs to be repaired, the paper scraps of other punching devices can be temporarily stored in the corresponding storage tank. At the same time, the first valve on the collection pipe corresponding to the storage tank can be closed separately, while the paper scraps of other punching devices are recovered normally, thereby improving the convenience of operation and ensuring the normal recovery of paper scraps;

[0019] 2. Furthermore, the capacity sensor provided on the storage tank can detect the paper scraps temporarily stored in the storage tank.

DETAILED DESCRIPTION

[0025] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, a paper scrap recycling device for a punched paper tape includes a temporary storage mechanism 1 for temporarily storing paper scraps and a negative pressure collecting mechanism 2 connected to the temporary storage mechanism 1 for conveying paper scraps, the temporary storage mechanism 1 and the negative pressure collecting mechanism 2 are connected by a pipeline 5; the pipeline 5 includes a branch pipeline 502 and a plurality of collecting pipes 503 connected to the branch pipeline 502, the temporary storage mechanism 1 includes a plurality of storage tanks 101 for temporarily storing paper scraps, and the plurality of storage tanks 101 are connected to the plurality of collecting pipes 503 one by one; the plurality of collecting pipes 503 are each provided with a first valve 5031 for controlling the switching of the collecting pipe 503, and the branch pipeline 502 is provided with a second valve 5021 for controlling the switching of the branch pipeline 502; the negative pressure collecting mechanism 2 includes a high-pressure fan 201 for providing conveying power, the high-pressure fan 201 is connected with a recycling bin 3 for recycling paper scraps, and the first valve 5031 and the second valve 5021 can be opened and closed manually or automatically.

[0027] Furthermore, the storage tank 101 of the temporary storage mechanism 1 is connected to the punching device. After the punching device punches holes in the paper tape, the paper scraps enter the storage tank 101 of the temporary storage mechanism 1 for temporary storage. Each punching device is connected to a storage tank 101. The collecting pipe 503 is connected to the storage tank 101. Each collecting pipe 503 is connected to the branch pipe 502. The temporary storage of paper scraps is achieved through the storage tank 101, and there is no need to keep the entire recycling device in an open state all the time, thereby saving energy.

[0028] In addition, a first valve 5031 is provided on the collecting pipe 503, and a second valve 5021 is provided on the branch pipe 502. Under the action of the first valve 5031, a single storage tank 101 can be opened and closed. At the same time, with the coordinated use of the first valve 5031 and the second valve 5021, all storage tanks 101 on the branch pipe 502 corresponding to the second valve 5021 can be opened and closed. When an individual punching device fails and needs to be repaired, paper scraps from other punching devices can be temporarily stored in the corresponding storage tank 101. At the same time, the first valve 5031 on the collecting pipe 503 corresponding to the storage tank 101 can also be closed separately and the second valve 5021 can be opened, so that paper scraps from other punching devices can be recovered normally, thereby improving the convenience of operation and ensuring the normal recovery of paper scraps.

[0029] The recovery device also includes a control system 4 for controlling the opening and closing of the first valve 5031, the second valve 5021 and the high-pressure fan 201. Under the action of the control system 4, the first valve 5031, the second valve 5021 and the high-pressure fan 201 are controlled to open and close, thereby ensuring the smooth operation of the recovery device.

[0030] The pipeline 5 also includes a main pipeline 501 connected to the branch pipeline 502. The main pipeline 501 is connected to one side of the high-pressure fan 201. Furthermore, a number of branch pipelines 502 are arranged in parallel along the length direction of the main pipeline 501. The main pipeline 501 is used to transport the paper scraps collected by the collecting pipes 503 connected to all the branch pipelines 502. Under the action of the high-pressure fan 201, the air is drawn out of the pipeline 5, thereby forming a negative pressure in the pipeline 5, thereby achieving the purpose of negative pressure transportation of paper scraps.

[0031] In addition, the first valve 5031 is arranged at the connection between the collecting pipe 503 and the branch pipe 502, and the second valve 5021 is arranged at the connection between each branch pipe 502 and the main pipe 501, ensuring that the first valve 5031 and the second valve 5021 accurately control the opening and closing of the corresponding collecting pipe 503 or branch pipe 502.

[0032] The first valve 5031 on the collecting pipe 503 and the second valve 5021 on the corresponding branch pipe 502 can be opened and closed synchronously, thereby ensuring the efficiency of paper scrap recovery and enabling the paper scraps to be transported in a timely manner.

[0033] Several storage tanks 101 are arranged in parallel along the length direction of the branch pipe 502, and the collecting pipe 503 is connected to the bottom of the storage tank 101, and the collecting pipe 503 is arranged vertically. Furthermore, multiple storage tanks 101 are arranged on each branch pipe 502, and each storage tank 101 is connected to a punching device. At the same time, multiple branch pipes 502 can be set, and then the number of corresponding storage tanks 101 and branch pipes 502 can be set according to actual conditions, thereby improving the practicability of the recycling device. At the same time, by arranging the collecting pipe 503 vertically, the weight of the paper scraps can assist in falling, which is conducive to recycling.

[0034] A capacity sensor 102 for detecting the capacity of the storage tank 101 is provided on each of the storage tanks 101. The capacity sensor 102 is disposed at the top of the storage tank 101. Furthermore, the capacity sensor 102 is disposed at the top opening of the storage tank 101. When the paper scraps temporarily stored in the storage tank 101 reach the upper capacity limit, the capacity sensor 102 transmits a signal to the control system 4. Under the action of the control system 4, the negative pressure collection mechanism 2 is started and the first valve 5031 and the second valve 5021 are opened to recycle the paper scraps. After the recycling is completed, the capacity sensor 102 transmits a signal to the control system 4 again, so that the negative pressure collection mechanism 2 is shut down and the first valve 5031 and the second valve 5021 are closed, thereby ensuring the recycling efficiency of the paper scraps.

[0035] The other side of the high-pressure fan 201 away from the main pipeline 501 is connected to a conveying pipe 202 for conveying paper scraps. The end of the conveying pipe 202 is connected to the recycling bin 3. The output wind force of the high-pressure fan 201 conveys the paper scraps to the recycling bin 3 through the conveying pipe 202, which is convenient for subsequent centralized processing, thereby realizing the final recycling of the paper scraps.

[0039] When recycling paper scraps, the opening and closing of the first valve 5031 can be controlled according to the paper scrap capacity in the storage tank 101, and the second valve 5021 can be opened at the same time, so as to realize independent recycling of paper scraps in several storage tanks 101. When all the storage tanks 101 are full of paper scraps, all the first valves 5031 can be opened and the second valve 5021 can be opened, so as to realize the recycling of paper scraps in all storage tanks 101.
