Description

Technical Field

[0001] This utility model relates to the field of air purification equipment manufacturing technology, specifically an automatic riveting and framing mechanism for bag filters. Background Technology

[0002] Bag filters are used in air filtration systems or equipment. A bag filter consists of multiple (e.g., six) filter bags assembled side-by-side. The process is roughly as follows: one end of each filter bag is open. First, adhesive is sprayed onto the outer surface of the inner frame. Then, the adhesive-coated inner frame is placed between the openings of two filter bags and pressed and clamped together (this can be called a composite clamping of the filter bag and the inner frame). Next, adjacent filter bags and inner frames are riveted together sequentially. Finally, a large outer frame assembles the inner frames at the openings of multiple filter bags together. To automate this process, each step must be automated. In existing technologies, the process of conveying the filter bags and adhesive-coated inner frames to a nailless riveting mechanism for pressing and clamping them together is generally done manually. This results in low efficiency, low automation, high labor costs, and unsatisfactory pressing effects. Therefore, an automatic riveting and framing mechanism for bag filters is proposed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1As shown, this utility model provides a technical solution: an automatic riveting and framing mechanism for a bag filter, including a support 1, characterized in that: the support 1 is provided with uprights 2 standing on both sides of the support 1, the two uprights 2 have a common nailless riveting mechanism 3 connecting the two uprights 2, the two uprights 2 are provided with two bracket assemblies 4 whose spacing can be adjusted along both sides of the support 1, the two bracket assemblies 4 are provided with sliding grooves 5 that allow the inner frame to slide along both ends of the support 1, and the support 1 is also provided with an outer frame framing mechanism 6 that can be movably connected.

[0028] Please see Figure 2 As shown, in this utility model: the nail-free riveting mechanism 3 includes a connecting seat 31, a vertical sliding assembly 32, a connecting plate 33, a horizontal sliding assembly 34, a nail-free riveting machine 35, and a drive unit 36. The drive unit 36 ​​is installed on the top of the connecting seat 31, and the drive unit 36 ​​is connected to the connecting plate 33. Vertical sliding assemblies 32 are respectively provided on both sides of the connecting seat 31, and the connecting plate 33 is slidably connected to the two vertical sliding assemblies 32. The horizontal sliding assembly 34 is installed on the connecting plate 33, and two horizontal sliding assemblies 34 are slidably connected to the horizontal sliding assembly 34. The two-way synchronous sliding nailless riveting machine 35 is provided with two sets. The transverse sliding component 34 is a positive and negative screw sleeve (the positive and negative screw sleeve is existing technology and will not be described in detail here). One end of the screw is equipped with a first drive motor 37. When the first drive motor 37 is turned, the two sets of nailless riveting machines 35 are moved to the inner frames of the filter bags to be bonded and adjacent to each other. Then the drive unit 36 ​​is a first cylinder. The first cylinder pushes the connecting plate 33 down until the two adjacent inner frame edges are clamped together and then riveted by the nailless riveting machine 35.

[0029] Please see Figure 3 As shown, the support assembly 4 includes a support 41, a synchronous adjustment device 42, a sliding adjustment device 43, and a positioning device 44. The synchronous adjustment device 42 is installed under the support 41, and the sliding adjustment device 43 is installed on the outer side of the two supports 41 respectively. The positioning device 44 is installed at one end of the top of the two supports 41 respectively. The synchronous adjustment device 42 can adjust the width of the support 41 within the support 1, making the equipment more widely applicable. The sliding adjustment device 43 can transport the riveted inner frame and filter bag to the outer frame mounting mechanism 6. The positioning device 44 facilitates positioning, so that the inner frame of the incoming material is clamped and accurately transported to the nailless riveting machine 35 for riveting.

[0030] Please see Figure 3 and Figure 4As shown, the synchronous adjustment device 42 includes a bidirectional lead screw module 421 mounted on one end of the support 1, a second drive motor 422 for driving the bidirectional lead screw module 421 to rotate, a transmission seat 423 mounted in the support 1, and a unidirectional lead screw module 424 mounted on the other end of the support 1. When the second drive motor 422 operates, the bidirectional lead screw module 421 (which is prior art and will not be described in detail here) rotates, and the unidirectional lead screw module 424 is driven to rotate synchronously through the transmission seat 423. When the second drive motor 422 rotates, the two supports 41 move closer to the sides of the support 1, so that the supports 41 can accommodate a larger inner frame, and vice versa, it is suitable for a smaller inner frame.

[0031] Please see Figure 3 and Figure 5 As shown, the sliding adjustment device 43 includes a third drive motor 431 disposed in the support 1, a first belt drive assembly 432, second belt drive assemblies 433 respectively perpendicularly disposed to the outside of the bracket 41, third belt drive assemblies 434 respectively horizontally disposed to the outside of the bracket 41, and a connecting rod 435 for connecting two of the vertically disposed second belt drive assemblies 433. The horizontally disposed third belt drive assembly 434 is located at the top of the bracket 41. The third drive motor 431 is connected to the first belt drive assembly 432. The first belt drive assembly 432 is connected to the middle section of the connecting rod 435. The two ends of the connecting rod 435 are respectively connected to two vertically disposed second belt drive assemblies 433. The two second belt drive assemblies 433 are respectively connected to two third belt drive assemblies 434. The belt drive assembly 434 and the third drive motor 431 operate. The first belt drive assembly 432 drives the connecting rod 435 to rotate. The connecting rod 435 drives the two second belt drive assemblies 433. The second belt drive assemblies 433 drive the third belt drive assembly 434. Since the third belt drive assembly 434 is provided with a clamping block 436 that clamps with the third belt drive assembly 434, and the two supports 41 are respectively provided with a sliding groove 5, the clamping block 436 is slidably connected to the sliding groove 5 outside the support 41. When the third belt drive assembly 434 rotates, it drives the clamping block 436 to slide along the support 41 towards the outer frame mounting mechanism 6. Thus, the inner frame can be gradually pushed towards the outer frame mounting mechanism 6. At the same time, the nailless riveting machine 35 above the inner frame gradually rivets the two adjacent inner frames.

[0032] The positioning device 44 is a second cylinder, which is installed on both sides of the bracket 41 at one end of the feed. The two second cylinders are installed on the slide groove 5. When the two third belt drives 434 rotate, they simultaneously drive the two second cylinders to slide.

[0033] Please see Figure 6 and Figure 7As shown, the outer frame mounting mechanism 6 includes a movable base 61, a slidable base plate 62 on the base 61, and an adjustable-space outer frame 63 on the base plate 62. A linear slide assembly 64 is installed in the base 61, and the base plate 62 is installed on the linear slide assembly 64. A bidirectional ball screw assembly 65, arranged perpendicularly to the linear slide assembly 64, is installed on the base plate 62. Both the linear slide assembly 64 and the bidirectional ball screw assembly 65 can be manually or automatically controlled. In this invention, the dragging of the linear slide assembly 64 and the bidirectional ball screw assembly 65 is done manually. The outer frame, in which the filter bag and the inner frame are installed, is placed inside the outer frame 63. Before the inner frame and the filter bag slide into the outer frame, the bidirectional ball screw assembly 65 is manually adjusted to clamp the outer frame. After the inner frame and the filter bag have slid to fill the outer frame, the outer frame 63 is manually dragged along the linear slide assembly 64 to the outer end, and then the outer frame is manually closed and locked.

[0034] The outer frame 63 is also provided with an inner frame moving assembly 7. The inner frame moving assembly 7 includes two sliding grooves 71 on both sides of the outer frame 63. A 7-shaped structural member 72 extending into the outer frame 63 is slidably connected in the two sliding grooves 71. A third cylinder 73 is installed on one side of the 7-shaped structural member 72. A protrusion 74 is connected to the working end of the third cylinder 73. When the inner frame and the filter bag slide to the junction of the bracket 41 and the outer frame 63, the third cylinder 73 operates, and the protrusion 74 is inserted into the inner frame. Since the inner frames are already riveted together in pairs, it is only necessary to drag the front inner frame towards the outer frame to drive the subsequent inner frames into the outer frame.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
