Description
Technical Field
[0001] This utility model belongs to the technical field of fabric processing equipment, specifically relating to a punching device with multi-hole integration. Background Technology
[0002] Perforation machines are widely used industrial machines, found in almost all industrial sectors. In the textile industry, they are also a crucial piece of textile machinery. Currently, the market requires perforation machines to punch holes in textile fabrics during processing, thereby achieving the desired fabric production effect.
[0003] Chinese patent with publication number "CN203096484U" discloses a multi-punch fabric punching machine with detachable punch and punch seat, including a base, a main body, a punch seat, a punch, a punch platform on the main body, at least two first loading and unloading slots on the punch platform, a detachable punch on the first loading and unloading slots, and a punch seat on the base that cooperates with the punch.
[0004] In the aforementioned patent, the punching machine uses multiple punches to cut multiple holes at once, primarily solving the problem that previous punching machines could only cut one hole at a time. However, when the punching machine in the aforementioned patent faces multiple punching operations of varying sizes, numbers, and intervals, the multiple punches driven by a single lifting drive source cannot meet the customer's different punching needs for the fabric. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, this utility model provides a punching device with multi-hole integration, which solves the technical problem that existing punching machines have too simple punching operations and cannot meet different punching needs.
[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:
[0007] A multi-hole integrated drilling device includes a mounting bracket, a power drive component, and multiple drilling assemblies arranged sequentially on the mounting bracket. Each drilling assembly includes a lifting bracket, a drill bit mounting seat, a drill bit, and a lifting drive component. The lifting bracket is connected to the drive end of the lifting drive component and can move vertically under the drive of the lifting drive component. The drill bit is rotatably connected to the bottom of the lifting bracket via the drill bit mounting seat.
[0008] A transmission component is provided between the power drive component and the drill bits in each drilling assembly, which can simultaneously drive the drill bits in each drilling assembly to rotate during the descent of the lifting bracket.
[0009] Furthermore, the moving assembly includes a timing belt, a driving timing pulley, and multiple driven timing pulleys. The driving timing pulley is connected to the power output end of the power drive component. Each driven timing pulley is rotatably connected to a mounting bracket and is driven by the driving timing pulley via a timing belt. Each driven timing pulley is equipped with a square spline shaft that connects to the drill bit in the corresponding drilling assembly. The square spline shaft is in sliding engagement with the driven timing pulley and can rotate under the drive of the driven timing pulley.
[0010] Furthermore, the mounting bracket is equipped with a tensioning assembly that cooperates with the timing belt. The tensioning assembly includes a tensioning wheel and an adjusting support. The tensioning wheel is rotatably connected to the mounting bracket via the adjusting support. The mounting bracket has a travel groove that cooperates with the adjusting support. The bottom of the adjusting support passes through the travel groove and slides in contact with it.
[0011] Furthermore, the lifting bracket includes a drive bracket, a drill bit holder bracket, and two guide rods. The drive bracket is fixed to the drive end of the lifting drive component. The drive bracket and the drill bit holder bracket are connected by a square spline shaft. The two guide shafts are respectively located at both ends of the drive bracket, and their bottoms pass through the drive bracket and the drill bit holder bracket in sequence.
[0012] Furthermore, fabric tensioning members are fixed to the bottom of the two guide rods. The fabric tensioning members have clearance through holes that mate with the drill bits in the corresponding punching assembly. The drill bits pass through these clearance through holes. A tension spring is provided between the fabric tensioning members and the drill bit holder.
[0013] Furthermore, the drill bits in each group of the drilling assemblies are hollow drill bits of 3mm, 6mm and 10mm respectively.
[0014] Furthermore, the square spline shaft and the drill bit holder are respectively provided with a first clearance groove and a second clearance groove communicating with the inner cavity of the drill bit. A ejector pin is fixed to the top of the mounting bracket. The bottom of the ejector pin passes through the first clearance groove and the second clearance groove in sequence and extends into the cavity of the corresponding drill bit.
[0015] Furthermore, the lifting drive component is a cylinder, and the power drive component is an electric motor.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. This utility model sets up multiple drilling components, and the drill bits in each drilling component can perform lifting and drilling operations under the drive of their respective lifting drive components, so that the drilling machine can meet the drilling needs of different sizes, quantities and intervals.
[0018] 2. This utility model involves creating a first clearance groove and a second clearance groove, respectively, on the square spline shaft and the drill bit holder bracket, which communicate with the inner cavity of the drill bit. A ejector pin is fixed at the top of the mounting bracket. The bottom of the ejector pin passes through the first clearance groove and the second clearance groove in sequence, extending into the cavity of the corresponding drill bit. This allows the ejector pin to push out any excess fabric temporarily stored inside the drill bit when the drill bit is lifted by the lifting drive component, preventing blockage inside the drill bit during prolonged operation.
[0019] 3. This utility model provides a fabric tensioning component at the bottom of the guide rod, so that when the drill bit holder is driven by the lifting drive to perform drilling operations, the fabric tensioning component will preferentially abut against the fabric, thus preventing the fabric from shrinking inward due to the insertion of the drill bit during the drilling operation.

Therefore, they should not be construed as limitations on this utility model.
[0027] The present invention will be further described below with reference to the accompanying drawings.
[0028] like Figure 1 and 2 As shown, a drilling device with multi-hole integration includes a mounting bracket 1, a power drive component 2, and multiple drilling assemblies arranged sequentially on the mounting bracket 1. Each drilling assembly includes a lifting bracket 3, a drill bit mounting seat 4, a drill bit 5, and a lifting drive component 6. The top of the lifting bracket 3 is connected to the drive end of the lifting drive component 6, enabling it to move vertically under the drive of the lifting drive component 6. The drill bit 5 is rotatably connected to the bottom of the lifting bracket 3 via the drill bit mounting seat 4.
[0029] A transmission component 7 is provided between the power drive component 2 and the drill bit 5 in each drilling assembly, which can simultaneously drive the drill bit 5 in each drilling assembly to work during the descent of the lifting bracket 3, so as to realize the drilling processing of the fabric.
[0030] The specific structure is as follows: Figure 2 and 3 As shown, the transmission assembly 7 includes a synchronous belt 7-1, a driving synchronous pulley 7-2, and multiple driven synchronous pulleys 7-3. The driving synchronous pulley 7-2 is connected to the power output end of the power drive component 2. Each driven synchronous pulley 7-3 is rotatably connected to the mounting bracket 1 and is transmitted to the driving synchronous pulley 7-2 via the synchronous belt 7-1. Each driven synchronous pulley 7-3 is equipped with a square spline shaft 7-4 that connects to the drill bit 5 in the corresponding drilling assembly. The square spline shaft 7-4 slides with the driven synchronous pulley 7-3 and can rotate under the drive of the driven synchronous pulley 7-3, thus enabling the drill bit 5 to perform drilling operations via the square spline shaft 7-4 after the drill bit 5 has descended.
[0031] Furthermore, such as Figure 2 and 4As shown, the mounting bracket 1 is equipped with a tensioning assembly 8 that cooperates with the timing belt 7-1 to adjust the tension of the timing belt 7-1. Specifically, the tensioning assembly 8 includes a tensioning wheel 8-1 and an adjusting support 8-2. The tensioning wheel 8-1 is rotatably connected to the mounting bracket 1 via the adjusting support 8-2. The mounting bracket 1 has a travel groove 9 that cooperates with the adjusting support 8-2. The bottom of the adjusting support 8-2 passes through the travel groove 9 and slides in contact with it. When tension adjustment is required, the operator loosens the nut at the bottom of the adjusting support 8-2, allowing the adjusting support 8-2 to slide. When the adjusting support 8-2 moves to the designated position, the nut is tightened to lock the position of the adjusting support 8-2.
[0032] like Figure 2 and 5 As shown, the lifting support 3 includes a drive support 3-1, a drill bit holder support 3-2, and two guide rods 3-3. The drive support 3-1 is fixed to the drive end of the lifting drive component 6. The drive support 3-1 and the drill bit holder support 3-2 are connected by a square spline shaft 7-4. When the drive support 3-1 is lifted by the lifting drive component 6, it will drive the drill bit holder support 3-2 and the drill bit 5 to lift synchronously via the square spline shaft 7-4. The two guide shafts are respectively located at both ends of the drive support 3-1, and their bottoms pass through the drive support 3-1 and the drill bit holder support 3-2 in sequence, providing guidance during the lifting operations of the drive support 3-1 and the drill bit holder support 3-2.
[0033] Furthermore, fabric tensioners 10 are fixed to the bottom of the two guide rods 3-3. The fabric tensioners 10 have clearance holes that mate with the drill bits 5 in the corresponding drilling assembly. The drill bits 5 pass through these clearance holes. A tension spring 11 is provided between the fabric tensioners 10 and the drill bit holder 3-2. When the drill bit holder 3-2 descends for drilling under the drive of the lifting drive 6, the fabric tensioners 10 will preferentially contact the fabric to prevent the fabric from shrinking inwards during the drilling process due to the insertion of the drill bits 5.
[0034] In this embodiment, the lifting drive component 6 is a cylinder, and the power drive component 2 is an electric motor.
[0035] In this embodiment, the drill bits 5 in each group of drilling assemblies are hollow drill bits 5 with diameters of 3mm, 6mm, and 10mm, respectively. The square spline shaft 7-4 and the drill bit holder 3-2 are respectively provided with a first clearance groove and a second clearance groove communicating with the inner cavity of the drill bit 5. A push pin 12 is fixed to the top of the mounting bracket 1. The bottom of the push pin 12 passes through the first clearance groove and the second clearance groove in sequence, extending into the cavity of the corresponding drill bit 5. When the drill bit 5 is lifted under the drive of the lifting drive 6, the push pin 12 will push out the excess fabric temporarily stored inside the drill bit 5, preventing blockage inside the drill bit 5 during long-term operation.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
