Description

Technical Field

[0001] This invention relates to an automatic bundling device for brooms, specifically an automatic bundling device for sanitation brooms. Background Technology

[0002] Sanitation workers consume a large number of brooms while sweeping the streets. These brooms are made by binding reeds to bamboo handles. Currently, the traditional method of manual binding is used, which is labor-intensive, inefficient, and does not effectively reduce costs. To address this, a semi-automatic broom-making machine has been invented, as disclosed in announcement CN214156511U. This machine includes: a rectangular double-layer frame, a hydraulic cylinder mounted on the upper layer of the frame, a push rod assembly fixed to the end of the hydraulic cylinder's rod, and a conical sleeve fitted onto the end of the push rod assembly. The body of the push rod assembly is detachably connected to the piston rod of the hydraulic cylinder via threads. The front end of the push rod assembly consists of two semi-circular rings, with the lower semi-circular ring fixedly connected to the body of the push rod assembly. This machine is mainly used to make broom heads made of bundled reeds. However, this structure only involves binding the reeds to create the broom head; the broom head still needs to be reassembled with the handle. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic bundling device for sanitation brooms. The handle is fixed to the automatic bundling device, and then an appropriate amount of golden thread grass is placed at the end of the handle and fixed. The automatic bundling device then automatically completes the bundling. The finished product is produced after bundling. It has the characteristics of reasonable structure, convenient operation and high efficiency.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] An automatic bundling device for sanitation brooms includes a frame, characterized in that: the frame is provided with a winding mechanism, a handle positioning mechanism, and a drive and control device; the handle positioning mechanism includes a rotating shaft pivotally connected to the frame, the rotating shaft having an axially penetrating shaft hole inside, and a handle clamping mechanism fixed to the rotating shaft at one end; the drive and control device drives the rotating shaft to rotate via a transmission mechanism; the winding mechanism includes a broom broom positioning and rotating mechanism and a winding and arranging mechanism; the broom broom positioning and rotating mechanism is pivotally connected to the frame and coaxially arranged with the rotating shaft; the winding and arranging mechanism is located on one side of the broom broom positioning and rotating mechanism; both the broom broom positioning and rotating mechanism and the winding and arranging mechanism are also driven by the drive and control device via a transmission mechanism.

[0006] The broom grass positioning and rotating mechanism includes a rotating frame with a main shaft pivotally connected to the machine frame. An air slip ring or an electric slip ring is sleeved on the main shaft. A broom grass clamping mechanism is provided on the rotating frame. The clamping mechanism is connected to a drive and control device through the air slip ring or the electric slip ring. The drive and control device controls the opening and closing of the clamping mechanism. The broom grass passes through the clamping opening of the clamping mechanism along the axial channel of the shaft hole.

[0007] The winding and laying mechanism includes a wire frame and a synchronous winding mechanism. The synchronous winding mechanism includes a wire frame and a lead screw. The lead screw is pivotally connected to the frame and is connected to the drive and control device through a transmission mechanism. The wire frame is sleeved on a guide rod, and the wire frame and the lead screw are threaded together.

[0008] A tension adjuster for the binding wire is also provided between the wire frame and the synchronous wire laying mechanism.

[0009] The aforementioned lead screw is a bidirectional lead screw.

[0010] The rotating frame has two sets, and the clamping angle of the clamping mechanism on each set of rotating frames is different.

[0011] The winding and laying mechanism is located between the two sets of rotating frame clamping ports.

[0012] The clamping mechanism includes a clamping plate and a cylinder. The cylinder is fixed on the rotating frame. The clamping plate has at least two plates. At least one clamping plate is connected to the telescopic rod of the cylinder, and the remaining clamping plates are either connected to the telescopic rod of the cylinder or connected to the rotating frame. The cylinder is connected to a slip ring via an air pipe. The slip ring is connected to an air source via an air pipe. A solenoid valve is connected in series on the air pipe. The solenoid valve is controlled by a drive and control device to open and close.

[0013] One of the rotating frames has an axial through hole on its main shaft, which is then fitted onto the rotating shaft through the axial through hole.

[0014] The rotating frame is provided with at least two axial guide holes, and a guide post is provided in each axial guide hole. The clamping mechanism is fixedly connected to the guide post, and the axial position of the clamping mechanism can be adjusted by extending and retracting the guide post in the axial guide hole.

[0015] This invention features a handle positioning mechanism and a broom grass positioning and rotating mechanism coaxially arranged. The handle positioning mechanism is used to fix the handle, while the broom grass positioning and rotating mechanism is used to clamp the broom grass and fix it to one end of the handle. Then, one end of the binding thread is knotted and fixed in the slot at one end of the handle. The drive and control device drives the handle positioning mechanism and the broom grass positioning and rotating mechanism to rotate synchronously through the transmission mechanism, so that the binding thread fixes the broom grass to one end of the handle. At the same time, the winding and arranging mechanism automatically arranges the binding thread neatly. The lead screw adopts a bidirectional lead screw, which can realize automatic bidirectional arrangement, suitable for multi-batch and multi-layer binding methods. The structure is very reasonable. During operation, the worker only needs to control the forward and reverse rotation of the motor of the drive and control device and the on and off of the solenoid valve. The operation is very convenient, greatly improving the binding efficiency and reducing the labor intensity. Attached Figure Description

[0024] like Figure 1-8As shown, an automatic bundling device for sanitation brooms includes a frame 1. The frame 1 is equipped with a winding mechanism, a handle positioning mechanism, and a drive and control device. The handle positioning mechanism includes a rotating shaft 2, which is pivotally connected to the frame 1. The rotating shaft 2 has an axially penetrating shaft hole 21 inside. One end of the rotating shaft 2 is equipped with a handle clamping mechanism 3, which is fixedly connected to the rotating shaft 2. The output end of the drive and control device drives the rotating shaft 2 to rotate through a transmission mechanism. The winding mechanism includes a broom grass positioning and rotating mechanism and a winding and arranging mechanism. The broom grass positioning and rotating mechanism is pivotally connected to the frame and coaxially arranged with the rotating shaft 2. The winding and arranging mechanism is located on one side of the broom grass positioning and rotating mechanism. The broom grass positioning and rotating mechanism and the winding and arranging mechanism are also driven by the drive and control device through a transmission mechanism.

[0025] The broom grass positioning and rotating mechanism includes a rotating frame 5, which has a main shaft 51. The main shaft 51 is pivotally connected to the frame 1. An air slip ring 4 is sleeved on the main shaft 51. A broom grass clamping mechanism 6 is provided on the rotating frame 5. The clamping mechanism 6 is connected to a drive and control device through the air slip ring 4. The drive and control device controls the opening and closing of the clamping mechanism 6. The broom grass passes through the clamping opening of the clamping mechanism 6 along the axial channel of the handle shaft hole.

[0026] The clamping mechanism 6 includes a clamping plate 61 and a cylinder 62. The cylinder 62 is fixed on the rotating frame 5. The clamping plate 61 has at least two pieces. At least one clamping plate 61 is connected to the telescopic rod of the cylinder 62. The remaining clamping plates 61 are either connected to the telescopic rod of the cylinder or connected to the rotating frame 5. The cylinder 62 is connected to the air slip ring 4 through an air pipe. The air slip ring 4 is connected to the air source through an air pipe. A solenoid valve is connected in series on the air pipe. The solenoid valve is controlled by a drive and control device to open and close.

[0027] One of the rotating frames 5 has an axial through hole 52 on its main shaft 51, and the main shaft 51 is sleeved on the rotating shaft 2 through the axial through hole 52.

[0028] The rotating frame 5 can be in one or more sets as needed. In this embodiment, two sets of structures are used. The initial clamping angle of the clamping mechanism 6 on each set of rotating frames 5 is different. This way, the golden silk grass is clamped from different angles and different parts, making it more stable and less likely to fall apart.

[0029] The axial position of the winding and laying mechanism is located on the side of the gap between the clamping openings of the two sets of rotating frames 5; the winding and laying mechanism includes a wire frame 71 and a synchronous laying mechanism, the synchronous laying mechanism includes a guide wire frame 72 and a lead screw 73, the lead screw 73 is a bidirectional lead screw, the lead screw 73 is pivotally connected to the frame 1, the lead screw 73 is connected to the drive and control device through a transmission mechanism, the guide wire frame 72 is sleeved on a guide rod 74, and the guide wire frame 72 and the lead screw 73 are threadedly engaged; a tension adjuster 75 for the binding wire is also provided between the wire frame 71 and the synchronous laying mechanism.

[0030] The handle clamping mechanism 3 includes a handle cylinder and a handle clamping plate. The handle cylinder is connected to the air slip ring 4 through an air pipe. The upper part of the rotating shaft is provided with a cut, which makes the upper part of the shaft hole 21 open. The handle clamping mechanism 3 is located above the open, and the handle clamping plate cooperates with the lower open to clamp the handle.

[0031] In operation, the handle 8 is first passed through the shaft hole 21 of the rotating shaft 2. The handle is then clamped by the handle clamping mechanism 3 to axially position the handle. One end of the binding rope is knotted and inserted into the slot at the end of the handle. Then, some golden silk grass is placed at the end of the handle. The clamping mechanisms 6 on the two sets of rotating frames fix the golden silk grass. Then, the motor is started to drive the rotating frame and the rotating shaft to rotate coaxially. At this time, the binding rope begins to bind and wrap the golden silk grass. Through the synchronous winding mechanism, the binding rope will be neatly arranged and wrapped. After the first layer is fixed, the motor stops and the clamping mechanism 6 is opened. Then, two more layers of golden silk grass are placed around the first layer of golden silk grass. Then, the clamping mechanism clamps the golden silk grass again and starts binding the two layers of golden silk grass. Generally, three layers of golden silk grass are placed and bound from the inside to the outside. The bound broom is firmly bound. In the whole operation, the worker only needs to place the golden silk grass according to the amount and then control the start and stop of the motor and the opening and closing of the cylinder. The work is very easy, the work efficiency is greatly improved, and the quality of the bound broom is reliable.

[0032] In addition, to accommodate brooms of different sizes, this invention includes a rotating frame 5 with an adjustable axial position for the clamping mechanism. The rotating frame 5 has at least two axial guide holes, each containing a guide post 53. The clamping mechanism 6 is fixedly connected to the guide post 53. The axial position of the clamping mechanism 6 can be adjusted by the movable extension and retraction of the guide post 53 within the axial guide hole. Thus, only the position of the clamping mechanism needs to be moved to accommodate brooms of different sizes, resulting in a more rational structure and greater ease of use.
