Description

Technical Field

[0001] This invention belongs to the field of brush manufacturing technology, specifically relating to a brush manufacturing device with a brush handle insertion guide device. Background Technology

[0002] Brushes are widely used in industrial and agricultural production. A brush mainly consists of a handle and a brush head. The brush head includes a brush head sleeve and bristles. The brush head sleeve has an internal cavity with a first opening on one side and a second opening on the other. The first end of the bristles passes through the second opening and partially fills the cavity, while the second end protrudes from the sleeve. The space from the first end of the bristles to the first opening within the cavity serves as the handle mounting cavity. In brush production, the brush head sleeve and bristles are usually assembled first to form the brush head, and then the handle and brush head are assembled.

[0003] To ensure a high success rate of the brush handle and brush head engagement, existing brush-making equipment often requires pre-processing of both. For example, the technical solution disclosed in patent document CN112841858A involves trimming the brush handle and pre-supporting the brush head. While this method improves the success rate, it still has drawbacks. First, the brush head is prone to deformation and scratches in the receiving cavity during pre-support, resulting in poor product aesthetics and impacting sales. Second, pre-processing the brush handle and brush head increases the overall brush-making process, reducing efficiency.

[0004] In view of this, the inventors aim to provide a brush making device with a brush handle insertion guide, which eliminates the need for pretreatment of the brush handle and brush head, and improves the success rate of handle installation. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems existing in the conventional technology and to provide a brush making device with a brush handle insertion guide device.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] A brush-making device with a brush handle insertion guide includes a brush head feeding device and a brush handle feeding device, and also includes a brush handle insertion guide. The brush head feeding device conveys the brush head to the assembly station along a first path, and the brush handle feeding device conveys the brush handle to the assembly station along a second path. The brush handle insertion guide is disposed on the second path.

[0008] Furthermore, in the aforementioned brush-making equipment with a brush handle insertion guide device, a clamping device is installed at the assembly station to facilitate the stable clamping of the delivered brush head.

[0009] Furthermore, in the aforementioned brush-making equipment with a brush handle insertion guide device, the clamping device integrates a nailing system capable of automatically nailing the snapped product.

[0010] Furthermore, in the above-mentioned brush-making equipment with a brush handle insertion guide device, the brush handle insertion guide device includes a guide plate, a rotation mechanism, and a displacement mechanism;

[0011] The guide plates are arranged in two rows, one above the other; one end of the guide plate is a rotary positioning end, and the other end is a flexible end.

[0012] The rotating mechanism is used to drive the guide plate to rotate around the rotating positioning end;

[0013] The displacement mechanism is used to drive the rotating mechanism and the guide plate to move synchronously.

[0014] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the flexible ends of the two rows of guide plates tend to approach and press against each other. The flexible ends of the two rows of guide plates are located on the snap-fit ​​path between the brush head and the brush handle. When the brush handle moves along the snap-fit ​​path, it can smoothly enter the receiving cavity of the brush head under the guidance of the guide plates.

[0015] Furthermore, in the brush-making equipment with the brush handle insertion guide device described above, the flexible ends of the two rows of guide plates can perform relative rotational separation under the action of the rotation mechanism during the process of entering the brush head receiving cavity.

[0016] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the position of the brush handle can be corrected by the two rows of guide plates during the process of the brush handle entering the brush head receiving cavity.

[0017] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the flexible ends of the two rows of guide plates extending into the brush head receiving cavity can convert the driving force of the brush handle forward into an internal supporting force on the brush head.

[0018] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the brush head sleeve in the brush head is made of metal or plastic, the brush handle is made of wood or plastic, and the guide plate is made of metal.

[0019] Furthermore, in the brush-making equipment with the brush handle insertion guide device described above, each row of guide plates is a single piece, or each row of guide plates contains multiple separate lobes, and the spacing between two adjacent lobes is fixed or adjustable.

[0020] Furthermore, in the brush-making device with the brush handle insertion guide device described above, at least one layer of non-bending support plate is added to the side of the guide plate near the brush head. The flexible end of the guide plate protrudes outward relative to the support plate, and the support plate provides support for the guide plate, so that the deformation range of the guide plate can be effectively controlled.

[0021] Furthermore, in the brush-making equipment with the brush handle insertion guide device described above, the rotating mechanism is an automatic operating mechanism that does not require a power component to drive it.

[0022] Furthermore, in the brush-making equipment with a brush handle insertion guide device described above, the rotating mechanism includes a positioning shaft, a rotating sleeve, a first base plate, and a return spring assembly. There are two positioning shafts, which are fixed to the first base plate in a vertical arrangement. A rotating sleeve is sleeved on the outer side of the positioning shaft. The rotating positioning end of the guide plate is mounted on the rotating sleeve. A return spring assembly for limiting the position of the rotating sleeve is mounted on the first base plate.

[0023] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the reset spring assembly includes a reset spring, a first hook, a second hook, and a hook fixing member. The first hook is fixed on the outside of the rotating sleeve, and the second hook is fixed to the first base plate through the hook fixing member. A reset spring is installed between the first hook and the second hook. When the rotating sleeve flips outward with the guide plate, the reset spring in the reset spring assembly deforms accordingly, and the rotating sleeve has a tendency to flip inward and reset under the action of the reset spring assembly.

[0024] Furthermore, in the brush-making device with a brush handle insertion guide device described above, the displacement mechanism includes a second base plate, a linear guide pair, and a drive push rod. The linear guide pair consists of a matching slide rail and a slider. The slide rail and the drive push rod are mounted on the second base plate. A first base plate is fixedly mounted on the outer side of the slider. The movable end of the drive push rod is connected to the first base plate. The length direction of the linear guide pair and the pushing direction of the drive push rod are both consistent with the snap-fit ​​path direction of the brush handle.

[0025] Furthermore, in the brush-making device with a brush handle insertion guide device described above, the rotating mechanism is an active action mechanism based on a power component. The rotating mechanism includes two rotating shafts and a power component for driving the two rotating shafts to rotate relative to each other. The rotating positioning end of the guide plate is mounted on the corresponding rotating shaft.

[0026] Furthermore, in the aforementioned brush-making device with a brush handle insertion guide, the power component includes an active push rod, which can be any one of an electric push rod, a pneumatic push rod, and a hydraulic push rod; the movable end of the active push rod is equipped with a push block, and the push block has toothed grooves on both sides near the rotating shaft; the two rotating shafts are provided with rotational support by a first base plate, and the active push rod is provided with fixed support by the first base plate; gears that mesh with the corresponding side toothed grooves are installed on the rotating shafts, and the relative rotation of the two rotating shafts can be achieved by extending and retracting the active push rod.

[0027] Furthermore, in the brush-making device with a brush handle insertion guide device described above, the power component includes a cam driven to rotate by a motor, two rotating shafts are provided with rotational support by a first base plate, a convex plate with a convex shaft is fixed on the rotating shaft, two eccentric shafts are mounted on the cam, and a connecting plate is sleeved between the convex shaft of the convex plate and the corresponding eccentric shaft, so that the relative rotation of the two rotating shafts can be achieved by rotating the cam.

[0028] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the power component includes two independent rotary motors, the two rotating shafts are provided with rotational support by the first base plate, and each of the two rotating shafts is driven to rotate by a rotary motor, the rotary motors being fixed on the first base plate by a motor bracket.

[0029] Furthermore, in the brush-making device with the brush handle insertion guide device described above, the power component includes a rotary motor, and the two rotating shafts are provided with rotational support by the first base plate. One of the rotating shafts is driven to rotate by the rotary motor. The rotary motor is fixed on the first base plate by a motor bracket, and meshing gear discs are installed on the two rotating shafts.

[0030] The beneficial effects of this invention are:

[0031] This invention relates to a brush-making equipment that adds a brush handle insertion guide device to the existing brush head feeding device and brush handle feeding device. The brush handle insertion guide device mainly consists of guide plates, a rotating mechanism, and a displacement mechanism. There are two rows of guide plates, arranged vertically. The flexible ends of the two rows of guide plates are located on the engagement path between the brush head and the brush handle. After the brush head reaches the engagement position, the brush handle, moving along the engagement path, smoothly enters the receiving cavity of the brush head under the guidance of the guide plates. During the process of entering the brush head receiving cavity, the flexible ends of the two rows of guide plates can rotate and separate relative to each other under the action of the rotating mechanism. During the process of the brush handle entering the brush head receiving cavity, the two rows of guide plates can correct the position of the brush handle (some brush handles may warp during the manufacturing process due to various factors; correction allows even warped brush handles to engage properly, avoiding resource waste). Simultaneously, the flexible ends of the two rows of guide plates extending into the brush head receiving cavity can convert the driving force of the brush handle's forward movement into an internal supporting force on the brush head. This method eliminates the need for pre-processing of the brush handle and brush head in brush manufacturing equipment, resulting in better product aesthetics and enhanced market competitiveness. Furthermore, it significantly simplifies the brush manufacturing process and improves efficiency while ensuring a high success rate for the brush handle and brush head snapping together.

[0032] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment provides a brush making device with a brush handle insertion guide device, including a brush head feeding device 1, a brush handle feeding device 2 and a brush handle insertion guide device 3. The brush head feeding device 1 transports the brush head 5 to the assembly station 4 along a first path, the brush handle feeding device 2 transports the brush handle 6 to the assembly station 4 along a second path, and the brush handle insertion guide device 3 is disposed on the second path.

[0048] In this embodiment, a clamping device is installed at assembly station 4 to securely hold the delivered brush head 5.

[0049] The clamping device integrates a nailing system that can automatically nail the clamped products.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that the clamping device integrates a nailing system that can automatically nail the snapped product.

[0052] Example 3

[0053] like Figures 2-5 As shown, this embodiment provides a brush manufacturing device with a brush handle insertion guide device, including a brush head feeding device 1, a brush handle feeding device 2, and a brush handle insertion guide device 3. The brush head feeding device 1 transports brush heads 5 to the assembly station 4 along a first path, and the brush handle feeding device 2 transports brush handles 6 to the assembly station 4 along a second path. The brush handle insertion guide device 3 is disposed on the second path. The brush handle insertion guide device 3 includes guide plates 301, a rotating mechanism, and a displacement mechanism. The guide plates 301 have two rows arranged vertically; one end of each guide plate 301 is a rotating positioning end, and the other end is a flexible end. The flexible ends of the two rows of guide plates 301 tend to approach and press against each other. The rotating mechanism drives the guide plates 301 to rotate around the rotating positioning end; the displacement mechanism drives the rotating mechanism and the guide plates 301 to move synchronously.

[0054] In this embodiment, the flexible ends of the two rows of guide plates 301 are located on the snap-fit ​​path between the brush head 5 and the brush handle 6. After the brush head 5 reaches the snap-fit ​​position, the brush handle 6 moves along the snap-fit ​​path and can smoothly enter the receiving cavity of the brush head 5 under the guidance of the guide plates 301. During the process of entering the receiving cavity of the brush head 5, the flexible ends of the two rows of guide plates 301 can perform relative rotational separation under the action of the rotation mechanism. During the process of entering the receiving cavity of the brush head 5, the position of the brush handle 6 can be corrected by the two rows of guide plates 301 (some brush handles 6 may warp due to some factors during the manufacturing process; after correction, the warped brush handle 6 can also be snapped in normally, avoiding resource waste). The flexible ends of the two rows of guide plates 301 extending into the receiving cavity of the brush head 5 can convert the driving force of the brush handle 6 forward into the internal supporting force on the brush head 5.

[0055] In this embodiment, the brush head cover of the brush head 5 is made of metal or plastic, the brush handle 6 is made of wood or plastic, and the guide plate 301 is made of metal.

[0056] In this embodiment, each row of guide plates 301 includes multiple separate petals or a single piece of plate; when the guide plate 301 uses multiple separate petals, the spacing between two adjacent petals is fixed or adjustable, and the distance between the two outermost petals is less than the lateral length of the brush head 5 receiving cavity.

[0057] In this embodiment, in order to achieve good deformation characteristics of the guide plate 301 only near the flexible end, a layer of non-bending support plate can be added to the side of the guide plate 301 near the brush head 5. The flexible end of the guide plate 301 protrudes outward relative to the support plate. The support plate can provide support for the guide plate 301 and effectively control its deformation range.

[0058] In this embodiment, the rotating mechanism is an automatic operating mechanism that does not require a power component. For example... Figures 5-7 As shown, the rotating mechanism includes a positioning shaft 302, a rotating sleeve 303, a first base plate 304, and a return spring assembly 305. There are two positioning shafts 302, which are fixed to the first base plate 304 in a vertically aligned manner. The rotating sleeve 303 is sleeved on the outer side of the positioning shaft 302. The rotation positioning end of the guide plate 301 is mounted on the rotating sleeve 303. The return spring assembly 305 for limiting the position of the rotating sleeve 303 is mounted on the first base plate 304.

[0059] In this embodiment, the reset spring assembly 305 includes a reset spring 305a, a first hook 305b, a second hook 305c, and a hook fixing member 305d. The first hook 305b is fixed to the outside of the rotating sleeve 303, and the second hook 305c is fixed to the first substrate 304 through the hook fixing member 305d. The reset spring 305a is installed between the first hook 305b and the second hook 305c. When the rotating sleeve 303 flips outward with the guide plate 301, the reset spring 305a in the reset spring 305a assembly deforms accordingly, and the rotating sleeve 303 has a tendency to flip inward and reset under the action of the reset spring assembly 305.

[0060] In this embodiment, the displacement mechanism includes a second base plate 306, a linear guide pair, and a drive push rod 309. The linear guide pair consists of a matching slide rail 307 and a slider 308. The slide rail 307 and the drive push rod 309 are mounted on the second base plate 306. A first base plate 304 is fixedly mounted on the outer side of the slider 308, and the movable end of the drive push rod 309 is connected to the first base plate 304. The length direction of the linear guide pair and the pushing direction of the drive push rod 309 are both consistent with the engagement path direction of the brush handle 6. The drive push rod 309 can be any one of an electric push rod, a hydraulic push rod, or a pneumatic push rod.

[0061] In this embodiment, the second substrate 306 can be installed on the brush-making equipment by conventional fixing methods such as welding or screw fixing, or the second substrate 306 can be supported by a bracket independent of the brush-making equipment.

[0062] The working principle of this embodiment is as follows:

[0063] like Figure 2 As shown in (a), the flexible ends of the two rows of guide plates 301 are positioned on the snap-fit ​​route between the brush head 5 and the brush handle 6.

[0064] like Figure 2 As shown in (b), after the brush head 5 reaches the snap-fit ​​station, its position is fixed. The displacement mechanism drives the two rows of guide plates 301 to move towards the brush head 5, so that the flexible ends of the two rows of guide plates 301 enter the receiving cavity of the brush head 5.

[0065] like Figure 2 As shown in (c), when the brush handle 6 moves along the snap-fit ​​path, it can smoothly enter the receiving cavity of the brush head 5 under the guidance of the guide plate 301; during the process of entering the receiving cavity of the brush head 5, the flexible ends of the two rows of guide plates 301 can perform relative rotational separation under the action of the rotation mechanism; during the process of entering the receiving cavity of the brush head 5, the position of the brush handle 6 can be corrected by the two rows of guide plates 301 (some brush handles 6 may warp due to some factors during the manufacturing process, and after correction, the warped brush handles 6 can also be snapped in normally, avoiding waste of resources), and the flexible ends of the two rows of guide plates 301 extending into the receiving cavity of the brush head 5 can convert the driving force of the brush handle 6 forward into the internal support force of the brush head 5.

[0066] like Figure 2 As shown in (d), the displacement mechanism drives the two rows of guide plates 301 to move away from the brush head 5, so that the flexible ends of the guide plates 301 separate from the receiving cavity of the brush head 5, without affecting the unloading operation of the assembled product. The brush head 5 and the brush handle 6 are directly fixed by snap-fit, and additional nails can be added as needed on the basis of snap-fit ​​fixing.

[0067] Example 4

[0068] The main difference between this embodiment and Embodiment 3 is that the rotating mechanism is an active actuation mechanism based on a power component. The rotating mechanism includes two rotating shafts 310 and a power component for driving the two rotating shafts 310 to rotate relative to each other. The rotation positioning end of the guide plate 301 is mounted on the corresponding rotating shaft 310. For example... Figure 6 As shown (guide plate 301 is not shown in the figure), the power assembly includes an active push rod, which can be any one of an electric push rod, a pneumatic push rod, and a hydraulic push rod; the movable end of the active push rod is equipped with a push block 312, and the push block 312 has toothed grooves on both sides near the rotating shaft 310. The two rotating shafts 310 are provided with rotational support by the first base plate 304, and the active push rod is provided with fixed support by the first base plate 304. The rotating shafts 310 are equipped with gears 311 that mesh with the corresponding side toothed grooves. The relative rotation of the two rotating shafts 310 can be achieved by the extension and retraction of the active push rod.

[0069] Example 5

[0070] The main difference between this embodiment and Embodiment 1 is that the rotating mechanism is an active actuation mechanism based on a power component. The rotating mechanism includes two rotating shafts 310 and a power component for driving the two rotating shafts 310 to rotate relative to each other. The rotation positioning end of the guide plate 301 is mounted on the corresponding rotating shaft 310. Figure 7 As shown (guide plate 301 is not shown in the figure), the power assembly includes a cam 313 driven to rotate by a motor, two rotating shafts 310 are provided with rotational support by a first base plate 304, a convex plate 314 with a convex shaft 315 is fixed on the rotating shaft 310, two eccentric shafts 316 are mounted on the cam 313, and a connecting plate 317 is sleeved between the convex shaft 315 of the convex plate 314 and the corresponding eccentric shaft 316. The relative rotation of the two rotating shafts can be achieved by rotating the cam 313.

[0071] Example 6

[0072] The main difference between this embodiment and Embodiment 1 is that the rotating mechanism is an active actuation mechanism based on a power component. The rotating mechanism includes two rotating shafts 310 and a power component for driving the two rotating shafts 310 to rotate relative to each other. The rotation positioning end of the guide plate 301 is mounted on the corresponding rotating shaft 310. Figure 8 As shown (guide plate 301 is not shown in the figure), the power assembly includes two independent rotary motors 318. The two rotating shafts 310 are provided with rotational support by the first base plate 304. Each of the two rotating shafts 310 is driven to rotate by a rotary motor 318. The rotary motors 318 are fixed on the first base plate 304 by motor brackets.

[0073] Example 7

[0074] The main difference between this embodiment and Embodiment 1 is that the rotating mechanism is an active actuation mechanism based on a power component. The rotating mechanism includes two rotating shafts 310 and a power component for driving the two rotating shafts 310 to rotate relative to each other. The rotation positioning end of the guide plate 301 is mounted on the corresponding rotating shaft 310. Figure 9 As shown (guide plate 301 is not shown in the figure), the power assembly includes a rotary motor 318 and two rotating shafts 310 that are provided with rotational support by the first base plate 304. One of the rotating shafts 310 is driven to rotate by the rotary motor 318. The rotary motor 318 is fixed on the first base plate 304 by a motor bracket. Gear discs 319 that mesh with each other are installed on the two rotating shafts 310.

[0075] The above solution is only a conventional example. This embodiment does not limit the implementation form of the power component. The power component can also be set as other conventional mechanisms that can drive two rotating shafts 310 to rotate relative to each other, such as eccentric drive.
