Description

Technical Field

[0001] This utility model relates to the field of sponge cutting machine technology, specifically to a hand roller assembly for a cross-cutting sponge machine. Background Technology

[0002] Currently, commonly used sponges are classified into three types according to their structure: high-density sponge, medium-density sponge, and low-density sponge. Among them, high-density sponge has many pores and is very full. Due to its good breathability and elasticity, it is often used as a material for sound-absorbing cotton, sofa cushions, and soft padding. Various automated equipment, such as sponge cutting machines, are usually used in the production of these sponge products.

[0003] Traditional beater rollers mostly use fixed metal paddles, which lack flexible adjustment capabilities. This makes it difficult to fully break up high-density sponges, while low-density sponges are prone to fiber breakage due to excessive beating. Moreover, the broken cotton material is transported by a single paddle roller, which is out of sync with the cutting rhythm and is prone to clogging at the cotton outlet, requiring frequent machine stops for cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a hand roller assembly for a cross-cutting sponge machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hand roller assembly for a cross-cutting sponge machine, comprising a hand roller mechanism, wherein the hand roller mechanism includes bearing seats disposed at both ends, a rotating shaft is rotatably mounted inside the bearing seats at both ends, and a driven sprocket is coaxially connected to the end of the rotating shaft, a dovetail track is axially opened on the outer circle of the rotating shaft, and a flexible hand is axially embedded in the outer circle track of the rotating shaft through a slider, and the flexible hand is fastened to the outer circle surface of the rotating shaft by bolts.

[0006] Furthermore, the bearing seat is fixedly installed at the top center of the frame, and a cotton outlet is connected to one side of the frame.

[0007] Furthermore, a feed inlet is connected to the other side of the frame, and a feed roller is rotatably installed at the connection end between the feed inlet and the frame.

[0008] Furthermore, a motor is fixedly installed at the bottom of the frame, and a gearbox is connected to the rotating end of the motor.

[0009] Furthermore, the rotating end of the gearbox has a drive sprocket coaxially, and a chain is externally engaged with the drive sprocket.

[0010] Furthermore, a cutter roller is rotatably mounted on one side of the top of the frame, and a chain two is engaged with the sprocket at the end of the cutter roller, and the end of the chain two away from the cutter roller rotates with the upper roller.

[0011] Furthermore, a pressure roller is rotatably mounted on the other side of the top of the frame, and a chain three is engaged with the sprocket at the end of the pressure roller, and the chain three rotates with the lower roller at the end away from the pressure roller.

[0012] Furthermore, the drive sprocket is driven by a chain that meshes with the corresponding sprocket shaft, cutter roller, pressure roller, and tensioning wheel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In use, the flexible beater of this utility model is composed of multiple independent units such as rubber paddles or elastic strips. The rotating shaft surface is provided with an axial dovetail groove track. The flexible beater unit is embedded in the track by a slider and can slide and adjust its position along the rotating shaft surface axially. Each flexible beater unit is equipped with a locking bolt at the bottom. After loosening, the spacing can be manually adjusted. After tightening, the running stability is ensured. This modular setting of the beater roller mechanism of this application supports quick replacement, and flexible beater units of different hardness can be mixed and used to adapt to the processing needs of sponges of different densities and materials.

[0015] 2. In use, this utility model achieves cross-shaped cutting of cotton material through the cooperation of the cutter roller and the pressure roller, and then the material is dispersed by the beater roller mechanism. The dispersed cotton material is fed into and out of the cotton nozzle by the upper and lower pusher rollers. The guide roller, pressure roller and beater roller mechanism are driven by a chain, so that under the action of the cutter roller and the pressure roller, the pressure roller fixes the sponge material and the cutter roller performs cross-cutting, ensuring that the cut is flat and without deformation. The flexible beater unit avoids damage to the sponge fiber and is conducive to subsequent filling application. The upper and lower pusher rollers are driven by the corresponding cutter roller and pressure roller through chains two and three, respectively, to realize the synchronous intake and exhaust of the dispersed sponge into the cotton nozzle, reducing clogging and reducing energy consumption.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3 As shown, a hand roller assembly for a cross-cutting sponge machine includes a hand roller mechanism 1. The hand roller mechanism 1 includes bearing seats 101 disposed at both ends. A rotating shaft 102 is rotatably mounted inside the bearing seats 101 at both ends. A driven sprocket 103 is coaxially connected to the end of the rotating shaft 102. A dovetail track is axially opened on the outer circle of the rotating shaft 102. A flexible hand 104 is axially embedded in the outer circle track of the rotating shaft 102 through a slider. The flexible hand 104 is fastened to the outer circle surface of the rotating shaft 102 by bolts.

[0022] The specific operation is as follows: The flexible beater 104 of this application is composed of multiple independent units such as rubber paddles or elastic strips. The surface of the rotating shaft 102 is provided with an axial dovetail groove track. The flexible beater 104 unit is embedded in the track by a slider and can slide and adjust its position along the axial surface of the rotating shaft 102. Each flexible beater 104 unit is equipped with a locking bolt at the bottom. After loosening, the spacing can be manually adjusted. After tightening, the running stability is ensured. This modular setting of the beater roller mechanism 1 of this application supports quick replacement, and flexible beater 104 units of different hardness can be mixed and used to adapt to the processing needs of sponges of different densities and materials.

Furthermore, a chain 11 is engaged with the sprocket at the end of the cutter roller 10, and the end of the chain 11 away from the cutter roller 10 rotates with the upper deflector roller 12. A pressure roller 13 is rotatably mounted on the other side of the top of the frame 2, and a chain 14 is engaged with the sprocket at the end of the pressure roller 13, and the end of the chain 14 away from the pressure roller 13 rotates with the lower deflector roller 15.

[0024] The specific operation is as follows: the cross-shaped cotton material is cut by the cooperation of the cutter roller 10 and the pressure roller 13, and then dispersed by the beater roller mechanism 1. The dispersed cotton material is fed into the cotton nozzle 3 by the upper pusher roller 12 and the lower pusher roller 15.
