Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and more specifically, to an exhaust gas treatment device for a plastic bottle cap printing equipment. Background Technology

[0002] During the production and processing of plastic bottle caps, trademarks, dates, and other markings need to be printed. This process generates a large amount of harmful gases, such as ozone produced by ultraviolet radiation and electric arc discharge, and ammonia gas produced by the volatilization of ammonia components in solvents and inks. These gases need to be purified before they can be released.

[0003] Based on the above, the inventors have discovered that existing exhaust gas treatment devices send exhaust gas to a specific treatment process for purification, resulting in high exhaust gas treatment costs. Furthermore, malfunctions in these devices are difficult to repair, forcing printing operations to stop and impacting the processing efficiency of plastic bottles. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an exhaust gas treatment device for plastic bottle cap printing equipment, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a tail gas treatment device for plastic bottle cap printing equipment. This solution is equipped with a filter component that is easy to install and disassemble, and can perform filtration directly during the tail gas emission process. It is simple and efficient to operate, and has low processing costs. In addition, a sealing component is set to keep the pipeline sealed during the replacement of the filter component, so that harmful gases are not easy to leak directly. The printing work does not need to be stopped, thus ensuring the processing efficiency of plastic bottles.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A tail gas treatment device for a plastic bottle cap printing equipment includes a printing chamber. Several exhaust pipes are fixedly connected to the top of the printing chamber. A guide pipe is fixedly connected to the top of each exhaust pipe. A connecting cylinder is centrally located on the opposite sides of two guide pipes. Sealing mechanisms are provided at both ends of the guide pipes near the inside. A filter element is fixedly connected centrally inside the connecting cylinder. An extension sleeve is provided through both ends of the connecting cylinder. An extrusion head and a threaded ring are fixedly connected to both ends of the extension sleeve, respectively.

[0009] The sealing mechanism includes a set of sealing blocks. The inner side of the sealing block is provided with a pressure groove, and a pair of guide rods are provided through the outer side of the sealing block. A return spring is sleeved on the outer side of the guide rods.

[0010] Furthermore, flanges are fixedly connected to both end faces of the air guide tube and the middle part of the extension sleeve.

[0011] Furthermore, the exhaust pipe and the air guide pipe are arranged perpendicularly, and two adjacent air guide pipes are connected through each other.

[0012] Furthermore, the threaded ring is located inside the connecting cylinder, and the threaded ring is threadedly connected to the connecting cylinder.

[0013] Furthermore, the extrusion head is located inside the air guide tube, and the side of the extrusion head is adapted to the pressure groove.

[0014] Furthermore, the sealing block is slidably connected to the inside of the air duct, and the sides of two adjacent sealing blocks are in contact.

[0015] Furthermore, the outermost ends of the guide rod and the return spring are both fixedly connected to the inner surface of the air duct, and the other end of the return spring is fixedly connected to the sealing block.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution rotates the extension sleeve to allow the extrusion head to enter the air guide pipe. The extrusion head extrudes the pressure groove, thereby causing the sealing block to slide outward. The air guide pipe is then in a through state. During exhaust gas treatment, harmful gases inside the printing room enter the air guide pipe through the exhaust pipe, and then pass through the connecting cylinder. The filter element inside the connecting cylinder performs the filtration work. Compared with the existing technology, the filter component is set up to be easy to install and disassemble. The filtration work can be carried out directly during the exhaust gas emission process. The operation is simple and efficient, and the treatment cost is low.

[0019] (2) By setting a sealing mechanism, when the filter needs to be replaced, the extension sleeve is rotated in the opposite direction to separate the extrusion head from the pressure groove. Under the action of the reset spring, the sealing block is reset. Through the cooperation of multiple sealing blocks, the gas guide tube is sealed. Compared with the existing technology, the sealing component is set to keep the pipeline sealed during the filter replacement process. Harmful gases are not easy to leak directly. The printing work does not need to be stopped, ensuring the processing efficiency of plastic bottles. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A tail gas treatment device for a plastic bottle cap printing equipment includes a printing room 1. Several exhaust pipes 2 are fixedly connected to the top of the printing room 1. A guide pipe 3 is fixedly connected to the top of the exhaust pipe 2. A connecting cylinder 4 is centrally arranged on the opposite side of two guide pipes 3. A sealing mechanism 5 is provided at both ends of the guide pipe 3 near the inside. A filter element 6 is fixedly connected centrally inside the connecting cylinder 4. An extension sleeve 7 is provided through both ends of the connecting cylinder 4. An extrusion head 8 and a threaded ring 9 are fixedly connected to both ends of the extension sleeve 7, respectively.

[0028] The sealing mechanism 5 includes a set of sealing blocks 10. The inner side of the sealing block 10 is provided with a pressure groove 11, and a pair of guide rods 12 are provided through the outer side of the sealing block 10. A reset spring 13 is sleeved on the outer side of the guide rods 12. In order to keep the pipeline sealed when the filter is replaced and prevent harmful gases from leaking directly, the sealing mechanism 5 is provided.

[0029] See Figure 2 Flanges are fixedly connected to both ends of the air duct 3 and the middle of the extension sleeve 7. The extension sleeve 7 is fixedly connected to the air duct 3 by screws passing through the corresponding two flanges.

[0030] See Figure 1 The exhaust pipe 2 and the air guide pipe 3 are set vertically, and two adjacent air guide pipes 3 are connected. When the external exhaust equipment is started, the harmful gas inside the printing room 1 enters the air guide pipe 3 through the exhaust pipe 2, then passes through the connecting cylinder 4, is filtered by the filter element 6 inside the connecting cylinder 4, and is then discharged.

[0031] See Figure 2The threaded ring 9 is located inside the connecting cylinder 4 and is threadedly connected to the connecting cylinder 4. By rotating the extension sleeve 7, the position of the extrusion head 8 can be adjusted through the threaded connection between the threaded ring 9 and the connecting cylinder 4.

[0032] See Figure 3 The extrusion head 8 is located inside the air guide pipe 3, and the side of the extrusion head 8 is adapted to the pressure groove 11. During the movement of the extrusion head 8, it extrudes the pressure groove 11, thereby causing the sealing block 10 to slide outward, so that the interior of the air guide pipe 3 is in a through state, thereby carrying out gas transportation.

[0033] See Figure 4 The sealing block 10 is slidably connected to the inside of the air guide tube 3, and the sides of two adjacent sealing blocks 10 are in contact. When the extrusion head 8 is separated from the pressure groove 11, the sealing block 10 is reset. Through the cooperation of multiple sealing blocks 10, the air guide tube 3 is sealed.

[0034] See Figure 4 The outermost ends of the guide rod 12 and the return spring 13 are fixedly connected to the inner surface of the air duct 3, and the other end of the return spring 13 is fixedly connected to the sealing block 10. When the sealing block 10 slides outward, the return spring 13 is compressed and deformed.

[0035] In use: Place the connecting sleeve 4 between two adjacent air guide pipes 3, rotate the extension sleeve 7, and connect it to the connecting sleeve 4 by threaded ring 9. The extrusion head 8 enters the air guide pipe 3, and at the same time, the flange in the middle of the extrusion head 8 fits with the flange on the end face of the air guide pipe 3 and is fixed by bolts. During the movement of the extrusion head 8, it extrudes the pressure groove 11, thereby causing the sealing block 10 to slide outward. When the sealing block 10 slides outward, the compression return spring 13 deforms, and the air guide pipe 3 is in a through state, thus carrying out gas transportation. Start the external exhaust equipment, and the harmful gas inside the printing room 1 enters the air guide pipe 3 through the exhaust pipe 2, then passes through the connecting sleeve 4, is filtered by the filter element 6 inside the connecting sleeve 4, and is then discharged. When the filter needs to be replaced, rotate the extension sleeve 7 in the opposite direction, so that the extrusion head 8 is separated from the pressure groove 11. Under the action of the return spring 13, the sealing block 10 is reset. Through the cooperation of multiple sealing blocks 10, the air guide pipe 3 is sealed, making it difficult for the harmful gas generated during printing to leak directly.
