Description

Technical Field

[0001] The utility model belongs to the technical field of baling machines, in particular to a roller driving structure of a baling machine. Background Art

[0002] A baler, also known as a strapping machine, a strapping machine or a tying machine, uses strapping tape to tie products or packages, then tightens and combines the two ends by hot-melting and gluing. The function of a baler is to reinforce the packaged items so that they do not fall apart during transportation or storage due to loose strapping. At the same time, the strapping should be neat and beautiful, so there are various balers on the market.

[0003] Existing balers all use powered rollers to transport the products to be packaged. A flat belt is provided under the powered roller, and a power wheel and a driven wheel are provided in the flat belt. The driven wheel is tensioned on the flat belt, and the power wheel is connected to a motor. The motor drives the power wheel to rotate, which drives the flat belt to move. The friction between the flat belt and the powered roller drives the powered roller to move. The driven wheel is generally fixed under the powered roller by a bracket. If there is an error in the size of the driven wheel and the powered roller, the flat belt between the driven wheel and the powered roller will not fit precisely, thereby affecting the movement of the powered roller, affecting the difficulty of installing the driven wheel, and affecting the overall assembly efficiency of the product.

[0030] The present invention is further described below in conjunction with specific embodiments:

[0031] A roller drive structure of a baler comprises a frame 1, a plurality of power rollers 2, a plurality of abutting wheels 3 and a transmission belt 4, Figure 1 , 2 As shown, the frame 1 is located in the baler. In the current baler, the frame 1 is generally provided with two, which are respectively arranged front and back, and the belt frame of the baler is generally arranged between the two frames 1. Figure 1 , 2 The frame 1 includes at least two installation panels 14 arranged on the left and right, and a plurality of power rollers 2 arranged in sequence are fixed between the installation panels 14. The power rollers 2 are arranged in sequence to form a conveying plane for conveying objects to be packaged. The objects to be packaged located on the conveying plane are driven by the rotation of the power rollers 2.

[0032] The abutment wheel 3 and the transmission belt 4 are located below the power roller 2. Figure 2 , 3 As shown, in this patent, the power roller 2 and the abutment wheel 3 are respectively arranged up and down, and each abutment wheel 3 is sequentially arranged between two different power rollers 2 along the conveying direction of the power roller 2. In this patent, a fixing seat 11 is installed on a mounting panel 14 on one side of the frame 1, and a fixing seat 11 is installed on the mounting panel 14 on the frame 1. Figure 3 , 4As shown, the cross section of the fixing seat 11 is "L" shaped, and a connecting bolt is provided on one side of the fixing seat 11. The fixing seat 11 is fixed to the mounting panel 14 of the frame 1 by connecting the screws, and the other side of the fixing seat 11 faces the bottom of the power roller 2. At this time, the abutting wheel 3 can be fixed on the other side of the fixing seat 11 to make the abutting wheel 3 located below the power roller 2. The transmission belt 4 is sleeved outside a plurality of abutting wheels 3. Since the abutting wheels 3 are located below the power roller 2, when the transmission belt 4 is sleeved outside a plurality of abutting wheels 3, a power assembly 5 for driving the transmission belt 4 to move around a plurality of abutting wheels 3 is provided in the transmission belt 4, which is used to drive the power roller 2 to rotate through the movement of the transmission belt 4; the transmission belt 4 is located between the abutting wheel 3 and the power roller 2, and the position of the abutting wheel 3 can be determined to make the transmission belt 4 squeezed between the abutting wheel 3 and the power roller 2. When the transmission belt 4 is driven to transmit, the power roller 2 can be driven to rotate through the friction of the transmission belt 4. The power assembly 5 includes a power wheel 51, which is located on one end of the transmission belt 4. The power wheel 51 is connected to a rotating power source 52 that drives it to move; the rotating power source 52 is specifically a driving motor. The power wheel 51 is fixed in the baler through a bracket and is located below the power roller 2. The transmission belt 4 is driven by the rotation of the power wheel 51.

[0033] Furthermore, each of the abutting wheels 3 is provided with an adjusting component 6, and the adjusting component 6 is used to make the abutting wheel 3 approach or move away from the power roller 2 to adjust the contact area between the transmission belt 4 and the power roller 2. Figure 3 , 4 As shown, the adjustment assembly 6 includes a support shaft 61 and an adjustment shaft 62. The support shaft 61 is inserted into the abutting wheel 3 and connected to the abutting wheel 3 through a bearing. In this embodiment, the fixing seat 11 is provided with a mounting opening 12. One end of the support shaft 61 is exposed outward and inserted into the mounting opening 12. A rotating hole for installing the adjustment shaft 62 is provided in the fixing seat 11 above the mounting opening 12. The adjustment shaft 62 is located in the rotating hole and connected to the support shaft 61. In this embodiment, the adjustment shaft 62 is connected to one end of the support shaft 61 through a threaded structure. By rotatably limiting the adjustment shaft 62 in the fixing seat 11, the adjustment shaft 62 is rotated to drive the support shaft 61 to rise and fall, thereby achieving adjustment.

[0034] The user can drive the abutment wheel 3 to rise and fall by rotating the adjusting shaft 62. Each abutment wheel 3 on the fixed seat 11 is connected to the adjusting shaft 62. The position adjustment between different abutment wheels 3 and different power rollers 2 can be achieved by operating different adjusting shafts 62 to compensate for the abutment wheel 3 that cannot be tensioned or is too tight due to manufacturing errors or installation errors, so that the transmission belt 4 is in a most suitable state.

[0035] Furthermore, one end of the support shaft 61 is provided with abutment boss 611, the size of which is larger than the size of the mounting opening 12. When the support shaft 61 passes through the mounting opening 12, the abutment boss 611 abuts against the fixing seat 11 on the outer edge of the mounting opening 12. When the support shaft 61 is installed with the abutment wheel 3, the abutment wheel 3 will give a downward force to the support shaft 61, which will cause the support shaft 61 to bend and be damaged over time, and affect the close contact between the abutment wheel 3 and the transmission belt 4; therefore, this patent alleviates the downward force received by the support shaft 61 by making the abutment boss 61 abut against the fixing seat 11 on the outer edge of the mounting opening 12, thereby increasing the overall service life.

[0036] Furthermore, the frame 1 is also provided with an auxiliary roller 13, which abuts between two adjacent power rollers 2; the auxiliary roller 13 and the abutting wheel 3 are respectively located on both sides of the power roller 2. The auxiliary roller 13 is arranged on a mounting panel 14 on one side of the frame 1 through a bracket, and the auxiliary roller 13 is a rubber wheel, on which a rubber surface in contact with the power roller 2 is provided, and is used to contact two adjacent power rollers 2. The auxiliary roller 13 is used to assist the abutting wheel 3 in transmitting the power roller 2, thereby alleviating the friction between the abutting wheel 3 and the power roller 2, and increasing the service life of the power roller 2 and the transmission belt 4.

[0037] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
