Description

Technical Field

[0001] This utility model relates to a processing device, and more specifically, to a sponge drilling and coring device. Background Technology

[0002] Sponges are widely used in cleaning, brush making, and other fields due to their excellent water absorption and porous nature. When used in sponge roller brushes, the sponge needs to be processed into a hollow cylindrical structure, and with a handle, it can be used for thick paint application, etc.

[0003] In the processing of sponge roller brushes, a sponge drilling and core-removing device is required. This device first drills concentric cylinders into the sponge using inner and outer cutting cylinders, and then pulls the smaller inner cylinder from the larger outer cylinder, forming a sponge cylinder with hollow holes. For example, Chinese Patent Publication No. CN113977698 A discloses "A Drilling and Core-Removing Device for Sponge Roller Brushes" (publication date: January 28, 2022), which includes a frame and a conveyor line mounted on the frame. A sponge block to be transported is placed on the conveyor line. The conveyor line is equipped with a drilling assembly for drilling holes in the sponge block and a core-removing assembly for removing the core from the drilled sponge block. The drilling assembly spans the conveyor line, and the sponge block passes under the drilling assembly and is drilled. The core-removing assembly spans the conveyor line and is located behind the drilling assembly. The drilled sponge block passes under the core-removing assembly, and the core-removing assembly pulls out the cotton core of the sponge block. The removed cotton core is placed on a waste disposal mechanism for waste disposal. The core-pulling equipment in the aforementioned patent application completes both drilling and core-pulling processes on the same machine, thus improving production efficiency to some extent. However, existing core-pulling equipment suffers from the following drawbacks, resulting in poor operational stability:

[0004] ① The sponge blocks are transported using a conveyor line, which requires a sponge placement basin. This basin is typically assembled from bakelite boards and mounted on the synchronous belt of the conveyor line via positioning posts. On one hand, large pieces of sponge need to be cut to ensure that the size of the sponge blocks to be transported meets the size requirements of the sponge placement basin. This cutting of sponge blocks not only increases processing steps but also increases waste and reduces the utilization rate of the sponge. On the other hand, the size of the cut sponge blocks and the sponge placement basin is difficult to be completely consistent, and there is usually a certain gap between them. During the movement of the sponge blocks, they are prone to displacement within the sponge placement basin, leading to errors in subsequent drilling and core sampling, and causing equipment malfunctions.

[0005] ②The first and second drill bits rotate synchronously in the same direction to drill, which will generate the same drilling torque on the sponge block, making the sponge block easy to move and deform, affecting the product processing accuracy.

[0006] Given the aforementioned shortcomings of existing sponge core drilling equipment, it is necessary to improve it to enhance product processing stability, processing accuracy, and production efficiency. Summary of the Invention

[0007] 1. Technical problem to be solved by the utility model

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings of existing sponge drilling and coring equipment and to provide an improved sponge drilling and coring equipment. The technical solution of this invention utilizes a gantry frame to drive the drilling mechanism and the coring mechanism to move relative to the bed for drilling and coring. The sponge body is fixed on the bed, which makes it easy to fix the sponge and reduces the risk of drilling and coring errors caused by sponge movement, thus improving the stability of drilling and coring processing. Furthermore, it eliminates the need for secondary cutting of the layered sponge body, reducing processing steps and sponge waste.

[0009] In addition, the outer and inner barrels of its drilling cutter set rotate in opposite directions, which can effectively reduce the drilling torque of the drilling cutter set on the sponge, resulting in higher drilling efficiency and higher processing accuracy.

[0010] 2. Technical Solution

[0011] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0012] This utility model relates to a sponge drilling and coring device, comprising:

[0022] Furthermore, the drilling mechanism also includes a drilling base plate and a first dual-axis motion assembly. The drilling base plate is mounted on the gantry via the first dual-axis motion assembly, and each set of drilling cutter groups is mounted on the drilling base plate. The first dual-axis motion assembly drives the drilling cutter groups to move along the Y-axis and Z-axis directions.

[0023] Furthermore, the core-taking mechanism has the same number of core-taking jaws as the drilling cutter set. Each of the core-taking jaws is spaced apart along the width of the bed on the core-taking base plate. The core-taking base plate is mounted on the gantry via a second dual-axis motion assembly, which drives the core-taking jaws to move along the Y-axis and Z-axis directions.

[0024] Furthermore, the gantry frame is also equipped with a tool barrel cooling mechanism for cooling down the drilling tool assembly.

[0025] Furthermore, the gantry frame is also equipped with a lifting pressure plate mechanism for pressing down the sponge body on the bed, and the tool barrel cooling mechanism is installed on the lifting pressure plate mechanism.

[0026] 3. Beneficial effects

[0027] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0028] (1) The present invention provides a sponge drilling and core extraction device, which includes a bed, a gantry frame, a drilling mechanism and a core extraction mechanism. The bed is used to fix the sponge to be processed. The gantry frame spans the bed and can move relative to the bed along the X-axis. The drilling mechanism and the core extraction mechanism are respectively installed on the gantry frame and are used to move with the gantry frame to drill and extract cores from the sponge on the bed. Compared with the prior art, the drilling mechanism and the core extraction mechanism are driven by the gantry frame to move relative to the bed to drill and extract cores. The sponge is fixed on the bed and does not move. It is easy to fix the sponge and it is not easy for the sponge to move and cause drilling and core extraction errors, thus improving the stability of drilling and core extraction processing. Moreover, there is no need to perform secondary cutting of the sponge after layer cutting, which reduces processing steps and sponge waste.

[0029] (2) The sponge drilling and coring equipment of this utility model has a gantry frame installed on the bed through an X-axis sliding assembly and driven to move along the X-axis direction by an X-axis drive mechanism, which ensures the stability and accuracy of the gantry frame's movement.

[0030] (3) The sponge drilling and core extraction device of this utility model has two or more sets of drilling cutter groups arranged at intervals along the width of the bed. Each set of drilling cutter groups has an outer cutter cylinder and an inner cutter cylinder with opposite rotation directions. The outer cutter cylinder is used to drill the outer circular hole, and the inner cutter cylinder is used to drill the core hole. The rotation directions of the outer cutter cylinder and the inner cutter cylinder are opposite, which can effectively reduce the drilling torque of the drilling cutter group on the sponge, resulting in higher drilling efficiency and higher processing accuracy.

[0031] (4) The sponge drilling and coring device of this utility model includes a drilling cutter group and a transmission box. The transmission box has a first drive shaft and a second drive shaft arranged coaxially. The outer cutter cylinder is installed at the lower end of the first drive shaft and the inner cutter cylinder is installed at the lower end of the second drive shaft. The upper end of the first drive shaft is connected to the first drilling motor through the first belt drive mechanism, and the upper end of the second drive shaft is connected to the second drilling motor through the second belt drive mechanism. The transmission box has a simple and compact structure and can realize dual-axis forward and reverse rotation output, which meets the need for drilling holes by rotating the outer cutter cylinder and the inner cutter cylinder in opposite directions.

[0032] (5) The sponge drilling and coring device of this utility model adopts a wave-shaped winding structure between the synchronous belt of the first belt drive mechanism and the second belt drive mechanism and each driven wheel, which ensures effective contact and transmission between the synchronous belt and each driven wheel and improves the transmission reliability.

[0033] (6) A sponge drilling and coring device of the present invention includes a drilling base plate and a first dual-axis motion assembly. The drilling base plate is installed on the gantry through the first dual-axis motion assembly. Each set of drilling cutter groups is installed on the drilling base plate. The drilling cutter groups are driven to move along the Y-axis and Z-axis by the first dual-axis motion assembly. The drilling cutter groups can be moved up and down and left and right by the first dual-axis motion assembly to realize the control of drilling depth and the staggering of the next row of drilling positions, thereby improving the utilization rate of sponge.

[0034] (7) A sponge drilling and coring device of the present invention has a coring mechanism with a number of coring jaws the same as the number of drilling cutter sets. Each coring jaw is spaced apart on the coring seat plate along the width direction of the bed. The coring seat plate is mounted on the gantry through a second dual-axis motion assembly. The second dual-axis motion assembly drives the coring jaws to move along the Y-axis and Z-axis. The coring mechanism can accurately cooperate with the drilling mechanism. When the drilling mechanism moves to the next row to drill, the coring mechanism just moves to the drilled position to perform coring. The action is stable and the processing efficiency is higher.

[0035] (8) The sponge drilling and core extraction device of this utility model is provided with a lifting pressure plate mechanism on the gantry frame for pressing down the sponge on the bed. The blade cooling mechanism is installed on the lifting pressure plate mechanism. The lifting pressure plate mechanism can press down the sponge during drilling and core extraction, improve the stability of drilling and core extraction, and prevent the sponge from moving. At the same time, the blade cooling mechanism can move up and down with the lifting pressure plate mechanism, which can better dissipate heat from the blade. Attached Figure Description

Detailed Implementation

[0042] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0043] [Example]

[0044] Combination Figure 1 and Figure 2 As shown, a sponge drilling and core extraction device according to this embodiment includes a bed 1, a gantry frame 2, a drilling mechanism 3, and a core extraction mechanism 4. The bed 1 is fixed and used to hold the sponge to be processed. The gantry frame 2 spans across the bed 1 and can move relative to the bed 1 along the X-axis, realizing step-by-step movement along the X-axis on the sponge to drill cores row by row. The drilling mechanism 3 is installed on the gantry frame 2 and is used to move with the gantry frame 2 and drill holes in the sponge on the bed 1, drilling concentric outer circular holes and core holes in the sponge. The core extraction mechanism 4 is installed on the gantry frame 2 and is located behind the drilling mechanism 3. It is used to extract the core from the drilled sponge and remove the sponge from the core hole. Compared with existing technologies, the drilling mechanism 3 and the core-taking mechanism 4 are driven by the gantry 2 to move relative to the bed 1 for drilling and core taking. The sponge is fixed on the bed 1 and does not move, which makes it easy to fix the sponge and reduces the possibility of drilling and core taking errors caused by sponge movement. The movement control precision of the gantry 2 is higher, which improves the stability of drilling and core taking. In addition, there is no need to perform secondary cutting of the sponge after layer cutting, which reduces processing steps and sponge waste.

[0045] Specifically, the gantry 2 is mounted on the bed 1 via the X-axis sliding assembly 5, and is driven to move along the X-axis direction by the X-axis drive mechanism 6, ensuring the stability and accuracy of the gantry's movement. (Refer to...) Figure 1As shown, the X-axis sliding assembly 5 includes an X-axis guide rail 51 and an X-axis slider 52. Two X-axis guide rails 51 are arranged parallel to each other on both sides of the bed 1. The X-axis slider 52 is fixed to the bottom of the gantry 2 and slides on the X-axis guide rail 51, so that the gantry 2 can move stably on the bed 1. The X-axis drive mechanism 6 preferably adopts a screw and nut transmission mechanism, including an X-axis drive screw 61 and an X-axis drive nut 62. The X-axis drive screw 61 is arranged on both sides of the bed 1 and parallel to the X-axis guide rail 51. The X-axis drive nut 62 is fixed to the lower end of the gantry 2 and is threadedly engaged with the X-axis drive screw 61 on the corresponding side. One end of each of the two X-axis drive screws 61 is provided with a sprocket, and is driven by an X-axis drive motor (not shown in the figure) through a transmission chain. The X-axis drive motor drives the X-axis drive screw 61 to rotate, and then drives the gantry 2 to move through the X-axis drive nut 62, with high accuracy in the moving distance.

[0046] like Figure 2 As shown, the aforementioned drilling mechanism 3 has two or more sets of drilling cutter groups 31 spaced apart along the width direction of the bed 1, which can complete a row of drilling operations at once, resulting in high processing efficiency. Combined with... Figure 4 As shown, in this embodiment, each drilling cutter set 31 has an outer cutter barrel 31-1 and an inner cutter barrel 31-2 rotating in opposite directions. The outer cutter barrel 31-1 is used to drill the outer circular hole, and the inner cutter barrel 31-2 is used to drill the core hole. Compared with the existing inner and outer cutter barrels rotating in the same direction, since the outer cutter barrel 31-1 and the inner cutter barrel 31-2 rotate in opposite directions during drilling, the drilling torque of the drilling cutter set 31 on the sponge can be effectively reduced, resulting in higher drilling efficiency and higher processing accuracy. See details below. Figure 4 As shown, the drilling tool assembly 31 also includes a transmission box 31-3. The transmission box 31-3 has a first drive shaft 31-3a and a second drive shaft 31-3b coaxially arranged. The first drive shaft 31-3a has a cylindrical structure, and the second drive shaft 31-3b is located inside the first drive shaft 31-3a. The first drive shaft 31-3a is supported in the transmission box 31-3 by bearings, and the second drive shaft 31-3b is supported in the first drive shaft 31-3a by bearings, so that the first drive shaft 31-3a and the second drive shaft 31-3b can rotate freely. The outer tool cylinder 31-1 is installed at the lower end of the first drive shaft 31-3a, and the inner tool cylinder 31-2 is installed at the lower end of the second drive shaft 31-3b. The upper end of the first drive shaft 31-3a is connected to the first drilling motor 31-5 through the first belt drive mechanism 31-4, and the upper end of the second drive shaft 31-3b is connected to the second drilling motor 31-7 through the second belt drive mechanism 31-6. The aforementioned transmission box 31-3 has a simple and compact structure, enabling dual-axis forward and reverse rotation output, thus meeting the need for drilling with the outer cutter barrel 31-1 and the inner cutter barrel 31-2 rotating in opposite directions. Further reference... Figure 3 and Figure 4As shown, the first belt drive mechanism 31-4 includes a first driving pulley 31-4a mounted on the output shaft of the first drilling motor 31-5, a first driven pulley 31-4b mounted on the upper end of each of the first drive shafts 31-3a, and a first synchronous belt 31-4c wound between the first driving pulley 31-4a and the first driven pulley 31-4b. The first synchronous belt 31-4c is wound in a wave pattern between the multiple first driven pulleys 31-4b. The second belt drive mechanism 31-6 includes a second driving pulley 31-6a mounted on the output shaft of the second drilling motor 31-7, a second driven pulley 31-6b mounted on the upper end of each of the second drive shafts 31-3b, and a second synchronous belt 31-6c wound between the second driving pulley 31-6a and the second driven pulley 31-6b. The second synchronous belt 31-6c is wound in a wave pattern between the multiple second driven pulleys 31-6b. The synchronous belt and each driven pulley employ a wave-like winding structure, ensuring effective contact and transmission between the synchronous belt and each driven pulley, thus improving transmission reliability. During operation, the sponge body is fixed on the loading table 1a of the bed 1. The first drilling motor 31-5 drives the outer cutter cylinder 31-1 to rotate, and the second drilling motor 31-7 drives the inner cutter cylinder 31-2 to rotate, controlling the rotation directions of the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 to be opposite. When the number of drilling cutter sets 31 is large, due to power limitations of the first drilling motor 31-5 and the second drilling motor 31-7, the drilling cutter sets 31 can be divided into two large groups, for example... Figure 3 There are a total of 9 drill bit sets 31. Five of them can be divided into one group, and the remaining 4 into another. Each drill bit set 31 in the two groups is driven by a separate drilling motor to ensure drilling efficiency. The specific division can be determined based on the number of drill bit sets 31 and the power of the drilling motors. The general principle is to ensure that each drill bit set 31 has sufficient drilling torque.

[0047] like Figure 1 and Figure 2As shown, the drilling mechanism 3 also includes a drilling base plate 32 and a first dual-axis motion assembly 33. The drilling base plate 32 is mounted on the gantry 2 via the first dual-axis motion assembly 33. Each set of drilling cutter groups 31 is mounted on the drilling base plate 32, and the first dual-axis motion assembly 33 drives the drilling cutter groups 31 to move along the Y-axis and Z-axis directions. Specifically, the transmission box 31-3, the first drilling motor 31-5, and the second drilling motor 31-7 in the drilling cutter group 31 are mounted on the drilling base plate 32. The first dual-axis motion assembly 33 can drive the drilling cutter groups 31 to move up and down and left and right, thereby controlling the drilling depth and staggering the positions of the next row of drill holes, improving the utilization rate of the sponge. The core-taking mechanism 4 has the same number of core-taking jaws 41 as the drilling tool set 31. These jaws 41 can be pneumatic grippers used to grip and pull out the sponge inside the core hole. Each core-taking jaw 41 is spaced apart on the core-taking base plate 42 along the width of the bed 1. The core-taking base plate 42 is mounted on the gantry 2 via a second dual-axis motion assembly 43, which drives the core-taking jaws 41 to move along the Y and Z axes. This core-taking mechanism 4 can accurately cooperate with the drilling mechanism 3. When the drilling mechanism 3 moves to the next row for drilling, the core-taking mechanism 4 moves to the already drilled position to take the core, resulting in stable operation and higher processing efficiency. The structures of the first dual-axis motion assembly 33 and the second dual-axis motion assembly 43 described above are similar. Movement in the Z-axis direction can be achieved using a ball screw transmission mechanism for high-precision lifting drive. Movement in the Y-axis direction can be achieved using linear drive mechanisms such as telescopic cylinders and electric push rods for offset movement of drilling and core-taking positions along the width of the bed 1. Figure 4 As shown, the cutting edge of the inner cutter cylinder 31-2 is higher than that of the outer cutter cylinder 31-1. During drilling, the core hole is not cut off; instead, the core-retrieving jaws 41 clamp the sponge inside the core hole, pull it out, and remove it. During processing, the gantry 2 moves the drilling mechanism 3 and the core-retrieving mechanism 4 to a set position. Then, the first drilling motor 31-5 and the second drilling motor 31-7 drive the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 to rotate, respectively. Simultaneously, the first dual-axis motion assembly 33 moves the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 downwards, causing them to drill to the set depth of the sponge. Afterward, the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 rise and reset. The gantry 2 drives the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 to move forward a certain distance. At the same time, the Y-axis drive component in the first dual-axis motion assembly 33 drives the outer cutter cylinder 31-1 and the inner cutter cylinder 31-2 to move laterally a certain distance, reaching the second row of drilling positions. Meanwhile, the core chuck 41 moves to the position of the drilled hole, and the second dual-axis motion assembly 43 drives the core chuck 41 to move down and clamp the sponge in the core hole. Then the core chuck 41 rises to pull out the sponge core column in the core hole.

[0048] like Figure 2As shown, the sponge drilling and coring equipment of this embodiment also has a cutter barrel cooling mechanism 7 on its gantry 2 for cooling the drill cutter assembly 31, which can cool the cutter barrel. Figure 2 As shown, the gantry 2 is also equipped with a lifting pressure plate mechanism 8 for pressing down the sponge on the bed 1. The tool barrel cooling mechanism 7 is installed on the lifting pressure plate mechanism 8. The lifting pressure plate mechanism 8 can press down the sponge during drilling and core taking, improve the stability of drilling and core taking, and prevent the sponge from moving. At the same time, the tool barrel cooling mechanism 7 can move up and down with the lifting pressure plate mechanism, which can better dissipate heat from the tool barrel.

[0049] This utility model discloses a sponge drilling and core extraction device, which can be used for processing sponge roller brushes. It uses a gantry frame to drive the drilling mechanism and the core extraction mechanism to move relative to the bed to perform drilling and core extraction. The sponge body is fixed on the bed and does not move, which makes it easy to fix the sponge and reduces the possibility of drilling and core extraction errors caused by sponge body movement, thus improving the stability of drilling and core extraction processing. In addition, it eliminates the need for secondary cutting of the sponge body after layer cutting, reducing processing steps and sponge waste.

[0050] In addition, the outer and inner barrels of its drilling cutter set rotate in opposite directions, which can effectively reduce the drilling torque of the drilling cutter set on the sponge, resulting in higher drilling efficiency and higher processing accuracy.

[0051] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
