Description

Technical Field

[0001] This utility model relates to the field of wind power transmission technology, and in particular to a negative pressure wind power supply device for a winding unit. Background Technology

[0002] In cigarette factories, the process of lifting tobacco shreds into cigarette rolls is mainly accomplished by process airflow. The air supply pipes of multiple cigarette rolling units are connected to the negative pressure fan in parallel. A filter device needs to be installed between the air supply pipes and the negative pressure fan to filter particulate matter.

[0003] In existing technologies, filter devices are often fixedly connected between the air supply pipe and the negative pressure fan. When the filter element needs to be cleaned or replaced, the bolts that fix it need to be unscrewed before the filter element can be cleaned or replaced. This method is cumbersome and time-consuming. Therefore, a roll-up negative pressure air supply device is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a negative pressure air supply device for a coiling unit, which has the advantages of being able to quickly clean or replace the filter element, thereby shortening the working time required for the operation and improving work efficiency.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] A negative pressure air supply device for a coiling machine includes a base. A negative pressure fan, a socket, and a frame are mounted on the top of the base. The socket has a diversion duct communicating with the negative pressure fan. A filter element is mounted at the end of the diversion duct away from the negative pressure fan. A plurality of air supply pipes communicating with the coiling machine are fixedly connected to the end of the frame away from the socket. A telescopic pipe assembly corresponding to the air supply pipes is mounted on the end of the frame near the socket. The end of the telescopic pipe assembly away from the frame is connected to an insertion pipe, which matches the diversion duct and the filter element. A movable block is fixedly connected to the outside of the insertion pipe. A drive assembly is mounted on the top of the socket. A plurality of transmission assemblies are mounted inside the socket. One end of each transmission assembly is connected to the drive assembly, and the other end passes through the socket and the movable block and is connected to the frame.

[0007] The negative pressure air supply device of this roll-up unit, when the filter element needs to be cleaned or replaced, drives the transmission component to rotate through the drive component, which in turn moves the movable block away from the socket, and then moves the insertion tube to separate from the diversion air duct, so that the filter element can be cleaned or replaced. During the above process, the telescopic tube component retracts simultaneously under the drive of the movable block, which has the advantages of being able to quickly clean or replace the filter element, thereby shortening the time required for the operation and improving work efficiency.

[0008] Preferably, in the above technical solution, the telescopic tube assembly includes: an outer cylinder, a movable inner cylinder, and a sealing ring. The outer cylinder is fixed to the frame plate and connected to the wind power supply pipe. The movable inner cylinder is slidably connected to the outer cylinder. The end of the movable inner cylinder away from the outer cylinder is fixedly connected to the insertion pipe. The sealing ring is sleeved on the outside of the movable inner cylinder and seals against the inner wall of the outer cylinder.

[0009] Preferably, in the above technical solution, a sealing gasket is fixedly provided on the side of the insertion tube near the socket, and the sealing gasket is adapted to the inner wall of the diversion duct for sealing between the insertion tube and the diversion duct.

[0010] As the movable block moves away from the socket, it drives the inner cylinder to slide to the right within the outer cylinder. During this process, the sealing ring maintains a seal between the outer cylinder and the inner cylinder. When the insertion tube enters the distribution duct, the sealing gasket seals the left side of the insertion tube with the distribution duct through elastic deformation.

[0011] Preferably, in the above technical solution, the drive assembly includes: a motor, a first pulley and a timing belt, the motor is fixedly installed on the top of the socket, the first pulley is fixedly connected to the output end of the motor, and the timing belt is sleeved on the outside of the first pulley.

[0012] Preferably, in the above technical solution, the transmission component includes: a threaded rod and a second pulley, one end of the threaded rod is rotatably connected to the socket, the other end is rotatably connected to the frame plate, the middle section of the threaded rod is threadedly connected to the movable block to drive the movable block to move, the second pulley is connected to the end of the threaded rod near the socket, and the second pulley is connected to the first pulley through a synchronous belt.

[0013] When the device needs cleaning or filter replacement, the motor is started. The motor output drives the first pulley to rotate, which in turn drives the second pulley to rotate synchronously via the synchronous belt. The second pulley drives the threaded rod to rotate synchronously in the socket. The force generated by the rotation of the threaded rod drives the movable block away from the socket, thereby separating the insertion tube from the diversion duct.

[0014] Preferably, in the above technical solution, one end of the diversion duct is connected to the air outlet of the negative pressure fan, and the other end forms multiple branch structures. Each branch structure is detachably connected to the filter element, and the number of branch structures matches the number of insertion tubes.

[0015] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0016] The negative pressure air supply device for the reel-and-roll unit disclosed in this application, through its structural design including a base, negative pressure fan, socket, and diversion duct, combined with a frame plate, air supply pipe, and telescopic pipe assembly, allows for easy cleaning or replacement of the filter element. When the filter element needs cleaning or replacement, the motor drives the transmission assembly, causing the movable block to separate the insertion pipe from the diversion duct without removing bolts. The telescopic pipe assembly retracts synchronously, and the sealing ring maintains a seal. Filter element maintenance can be completed simply by reversing the motor, and the sealing gasket ensures a tight seal upon resetting after cleaning or replacement. This design completely eliminates the traditional bolt-fixing method, simplifying the cumbersome operation to electric control, significantly reducing working hours, greatly improving work efficiency, and effectively solving the problem of long operation times in existing technologies.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] Unless otherwise specified, the experimental methods used in the following examples are conventional methods, and the materials and reagents used are commercially available. Unless otherwise specified, the equipment used in the experiments is well known to those skilled in the art.

[0026] A negative pressure air supply device for a coiling machine includes a base 1. A negative pressure fan 2, a socket 3, and a frame 6 are mounted on the top of the base 1. The socket 3 has a diversion duct 4 connected to and to the right side of the negative pressure fan 2. Each end of the diversion duct 4 away from the negative pressure fan 2 has a matching filter element 5. The right side of the frame 6 is fixedly connected to air supply pipes 7, which are longitudinally evenly distributed and connected to the corresponding coiling machine. The left side of the frame 6 has telescopic pipe assemblies 8, which are longitudinally evenly distributed and connected to the corresponding air supply pipes 7. An insertion pipe 9 is connected to the left end of the telescopic pipe assembly 8. The insertion pipe 9 is compatible with both the diversion duct 4 and the filter element 5. A movable block 10 is fixedly connected to the outer side of the insertion pipe 9. The top of the socket 3 has a drive assembly 11. The socket 3 has a transmission assembly 12, which is longitudinally evenly distributed, drively connected to the drive assembly 11, and threadedly connected to the movable block 10. The right side of the transmission assembly 12 is rotatably connected to the left side of the frame 6.

[0027] The drive assembly 11 includes a motor 111, a first pulley 112 and a timing belt 113. The top of the socket 3 is provided with a motor 111, the output end of the motor 111 is fixedly connected to the first pulley 112, and the timing belt 113 is sleeved on the outside of the first pulley 112.

[0028] The transmission assembly 12 includes a threaded rod 121 and a second pulley 122. The socket 3 is rotatably connected to the threaded rods 121 that are longitudinally and equally spaced and rotatably connected to the left side of the frame plate 6. The threaded rods 121 are threadedly connected to the movable block 10. The left end of the threaded rod 121 is fixedly connected to the second pulley 122. The second pulley 122 and the first pulley 112 are fitted with the same synchronous belt 113 on their outer sides.

[0029] When the device needs to be cleaned or the filter element 5 is replaced, the motor 111 is started. The output end of the motor 111 drives the first pulley 112 to rotate, and then drives the second pulley 122 to rotate synchronously through the synchronous belt 113. The second pulley 122 drives the threaded rod 121 to rotate synchronously in the socket 3. The force generated by the rotation of the thread drives the movable block 10 away from the socket 3, which can drive the insertion tube 9 to separate from the diversion duct 4.

[0030] The telescopic tube assembly 8 includes an outer cylinder 801, a movable inner cylinder 802, and a sealing ring 803. The left side of the frame plate 6 is fixedly connected to an outer cylinder 801 that is longitudinally and evenly distributed and communicates with the corresponding wind power supply pipe 7. The inner side of the outer cylinder 801 is slidably connected to a movable inner cylinder 802 that extends to its left side. The outer side of the movable inner cylinder 802 is fitted with a sealing ring 803 that is adapted to the outer cylinder 801. The left end of the movable inner cylinder 802 is fixedly connected to an insertion pipe 9 that communicates with it.

[0031] As the movable block 10 moves away from the socket 3, the movable block 10 drives the movable inner cylinder 802 to slide to the right inside the outer cylinder 801. During this process, the sealing ring 803 always seals between the outer cylinder 801 and the movable inner cylinder 802.

[0032] The left end of the insertion tube 9 is fixedly connected to a sealing gasket 13 that is compatible with the diversion duct 4; when the insertion tube 9 enters the diversion duct 4, the sealing gasket 13 seals the left side of the insertion tube 9 and the diversion duct 4 through elastic deformation.

[0033] The working principle of the negative pressure air supply device for the coiling unit in this application is as follows:

[0034] Step 1: When the device needs to be cleaned or the filter element 5 is replaced, start the motor 111. The output end of the motor 111 drives the first pulley 112 to rotate, and then drives the second pulley 122 to rotate synchronously through the synchronous belt 113. The second pulley 122 drives the threaded rod 121 to rotate synchronously in the socket 3. The force generated by the rotation of the thread drives the movable block 10 away from the socket 3, which can drive the insertion tube 9 to separate from the diversion air duct 4.

[0035] Step 2: During the above process, as the movable block 10 moves away from the socket 3, the movable block 10 drives the movable inner cylinder 802 to slide to the right inside the outer cylinder 801, and the sealing ring 803 always seals the space between the outer cylinder 801 and the movable inner cylinder 802.

[0036] Step 3: After cleaning or replacing the filter element 5, reverse the motor 111, and then move the movable block 10 toward the socket 3 until the insertion tube 9 enters the diversion duct 4, and the sealing gasket 13 undergoes elastic deformation. The sealing gasket 13 seals the left side of the insertion tube 9 and the diversion duct 4 through elastic deformation, thus completing the cleaning or replacement of the filter element 5.

[0037] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
