Description

Technical Field

[0001] The utility model relates to the technical field of baling machines, in particular to a pressure-stabilized baling machine. Background Art

[0002] With the development of modern industry and the improvement of transportation roads, more and more machined parts and products need to be transferred and moved to various regions so that the products can be processed and assembled as a whole. Before transportation, multiple products need to be packaged and packed. The usual practice is to stack the products on pallets and wrap them with stretch film. However, the existing balers have unstable pressure during packaging, which leads to poor consistency of the packaged products. As a result, the packaged products will be skewed and uneven due to the unstable packaging pressure, resulting in unsightly packaging. Utility Model Content

[0003] The purpose of the present invention is to provide a pressure-stable baler to solve the problem in the background art that the baler pressure is unstable, resulting in untidy and unsightly packaging.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pressure-stabilized baler, comprising a frame, a servo motor is fixedly mounted on the outer surface of one end of the frame, and the output end of the servo motor passes through the side surface of the frame, a control box is fixedly mounted on the outer surface of the frame close to the servo motor, a disc motor is fixedly mounted on the outer surface of the frame away from the control box, a load-bearing platform is provided on the side surface of the frame, and a pressure relay is fixedly mounted on the outer surface of the load-bearing platform, a rotating mechanism is provided between the pressure relay and the load-bearing platform, and the rotating mechanism enables the stacked products to be packaged without tilting or falling due to excessive packaging pressure, thereby ensuring the aesthetics of the packaging.

[0005] Preferably, the rotating mechanism includes: a rotating unloading arm, which is rotatably mounted on the outer surface of the load-bearing platform, and a positioning torsion spring is inserted between the load-bearing platform and the rotating unloading arm, the rotating unloading arm is eccentrically designed, and one end of the rotating unloading arm is in contact with the outer surface of the pressure relay, and a fixed cover is threadedly mounted on the end of the rotating unloading arm away from the pressure relay, and the fixed cover is in contact with the outer surface of the wrapped film roll.

[0006] By adopting the above technical solution, when packaging the stacked and packaged products, as the products rotate, the stretch film roll will unwind and drive the rotating unwinding arm to move. At this time, the rotating unwinding arm will move and contact the pressure relay. When the value set by the pressure relay is reached, the rotation speed of the disc motor will be slowed down, so that the product can rotate at an appropriate speed, thereby achieving stable pressure and preventing the product from being skewed and remaining neat after being wrapped.

[0007] Preferably, a rotating engagement mechanism is provided between the frame and the servo motor, and the rotating engagement mechanism enables the load-bearing platform to move up and down more accurately, so that the stretch film can automatically stop after exceeding the height of the product during packaging.

[0008] By adopting the above technical solution, when wrapping products of different heights, the electric eye can be used for detection. When the electric eye exceeds the height of the product, the disc motor will stop working, and the packaging and wrapping will stop automatically after completion.

[0009] Preferably, the rotating engagement mechanism includes: a worm, which is rotatably installed inside the frame, and a screw is rotatably installed inside the frame, a worm wheel is fixedly installed on one end of the screw close to the servo motor, and the worm wheel is engaged with the worm, a slider is slidably installed inside the frame, and the slider is fixedly connected to the load-bearing platform, the slider is threadedly connected to the screw, and a detection electric eye is fixedly installed on the outer surface of the load-bearing platform.

[0010] By adopting the above technical solution, the rotation of the servo motor can drive the worm to rotate together, so that the worm wheel meshing with the worm rotates together, and at the same time drives the screw to rotate together, so that the slider can slide stably inside the frame. Through the self-locking property of the worm and the worm wheel, the slider will not be dragged due to rotation during winding and packaging, and the accuracy of the slider movement can be improved.

[0011] Preferably, a platform plate is fixedly mounted on the output end of the disc motor, and the platform plate and the disc motor are concentrically designed, and a bearing is provided between the platform plate and the frame.

[0012] By adopting the above technical solution, the platform plate is driven to rotate by adjusting the disc motor, so that the products placed on the platform plate can be rotated for easy packaging, and the bearings can better provide support for the platform plate, allowing the platform plate to withstand greater pressure and rotate more smoothly.

[0013] Preferably, the outer surface of the frame is provided with marking lines, and the marking lines are in contact with the ground, a tank chain is provided between the load-bearing platform and the frame, and through holes are provided on the outer surfaces of the frame and the control box.

[0014] By adopting the above technical solution, a forklift can unload the product through the marked line when placing the product, and the tank chain between the load-bearing platform and the frame can effectively protect the circuits of the pressure relay and the detection electric eye, reducing the chance of the circuit entering the slider and the frame and being damaged and broken when the load-bearing platform moves. At the same time, the through holes opened in the frame and the control box can easily connect the circuit to the control box.

[0015] Preferably, an imaging device is provided on one side of the frame, and the imaging device is placed on the ground, and an imaging screen is fixedly mounted on the side surface of one end of the frame close to the control box.

[0016] By adopting the above technical solution, the image of the product can be projected onto the display screen through the imaging device when the product is placed on the platform, so that the operator can directly observe the position where the product is placed, improve the concentricity of the product when it is placed on the platform, and prevent uneven pressure due to eccentricity during wrapping, and there is no need for the operator to get off the vehicle to check and adjust the discharge position.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the pressure-stabilized baler:

[0018] 1. After placing the packaged product on the platform by forklift, the stretch film can be pulled onto the product to be packaged. Then the disc motor can be started. When the product rotates, the stretch film will be pulled out. At this time, the rotating discharge arm will move along with it and squeeze the pressure relay. When the pressure relay reaches the set value, the disc motor will maintain the rotation speed, so that the packaging pressure remains stable. The product will not tilt due to unstable wrapping pressure, ensuring the beautiful packaging of the product.

[0019] 2. As the disc motor starts, the servo motor drives the worm to rotate, causing the worm wheel meshing with the worm to rotate. As the worm wheel rotates, the screw is driven to rotate, allowing the slider to move slowly inside the frame. The self-locking nature of the worm and worm wheel prevents the slider from moving due to pulling or other reasons, ensuring the consistency of the wrapping distance when wrapping the product and enabling the rotating unloading arm to rise slowly. When the detection electric eye cannot detect the product, the disc motor will stop running, completing the packaging of the product.

[0020] 3. When placing the product by forklift, you only need to follow the markings on the ground to guide the forklift into the accurate placement position. The image capturing device can be used to shoot from the side to show the position of the product on the platform. The image captured by the image capturing device can be projected on the display screen, making it convenient for the forklift operator to locate the product on the vehicle accurately. The product can be placed on the platform accurately, ensuring the concentricity of the platform and the placed product, and the disc motor will not eccentric when driving the platform to rotate, thereby reducing the pressure instability caused by eccentricity, improving the stability of the product during packaging, and ensuring the beauty of the product after packaging.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The utility model provides a technical solution: a pressure-stabilized baler, comprising a frame 1, a servo motor 2 is fixedly mounted on the outer surface of one end of the frame 1, and the output end of the servo motor 2 passes through the side surface of the frame 1, a control box 18 is fixedly mounted on the outer surface of the frame 1 close to the servo motor 2, a disc motor 4 is fixedly mounted on the outer surface of the end of the frame 1 away from the control box 18, a load-bearing platform 10 is provided on the side surface of the frame 1, and a pressure relay 13 is fixedly mounted on the outer surface of the load-bearing platform 10, a rotating mechanism is provided between the pressure relay 13 and the load-bearing platform 10, and the rotating mechanism enables the stacked products to be packaged without tilting or falling due to excessive packaging pressure, thereby ensuring the aesthetics of the packaging.

[0030] The pressure value set by the pressure relay 13 can be adjusted through the control box 18 to facilitate the pressure stability when packaging products of different sizes, weights and quantities, and reduce the probability of products falling due to excessive packaging pressure during packaging.

[0031] The rotating mechanism includes: a rotating unloading arm 11, which is rotatably mounted on the outer surface of the load-bearing platform 10, and a positioning torsion spring 12 is inserted between the load-bearing platform 10 and the rotating unloading arm 11. The rotating unloading arm 11 is eccentrically designed, and one end of the rotating unloading arm 11 is in contact with the outer surface of the pressure relay 13. A fixing cover 15 is threadedly mounted on the end of the rotating unloading arm 11 away from the pressure relay 13, and the fixing cover 15 is in contact with the outer surface of the wrapped film roll.

[0032] When in use, the stretch film needs to be inserted into the inside of the rotating discharge arm 11 and the stretch film is limited by the fixed cover 15. Then the stretch film can be pulled out and clamped into the product. The disc motor 4 is started to drive the platform plate 5 to rotate, so that the product placed on the platform plate 5 rotates together. As the product rotates, the stretch film will be pulled out and drive the rotating discharge arm 11 to move, and the rotating discharge arm 11 will squeeze the pressure relay 13. When the pressure of the pressure relay 13 reaches the set value, the disc motor 4 will maintain the rotation speed to keep the pressure during packaging consistent, and the product will not tilt after packaging due to unstable pressure of winding and packaging.

[0033] A rotating engagement mechanism is provided between the frame 1 and the servo motor 2. The rotating engagement mechanism enables the load-bearing platform 10 to move up and down more accurately, so that the wrapping film can automatically stop after exceeding the height of the product during packaging. The rotating engagement mechanism includes: a worm 3, which is rotatably installed inside the frame 1, and a screw 8 is rotatably installed inside the frame 1. A worm gear 7 is fixedly installed at one end of the screw 8 close to the servo motor 2, and the worm gear 7 is meshed with the worm 3. A slider 9 is slidably installed inside the frame 1, and the slider 9 is fixedly connected to the load-bearing platform 10. The slider 9 is threadedly connected to the screw 8, and a detection electric eye 14 is fixedly installed on the outer surface of the load-bearing platform 10.

[0034] When the disc motor 4 is started, the servo motor 2 will also be started, so that the servo motor 2 drives the worm 3 to rotate, and the rotation of the worm 3 drives the worm wheel 7 and the screw 8 to rotate together. The self-locking property of the worm 3 and the worm wheel 7 allows the slider 9 to move slowly and stably inside the frame 1, ensuring the consistency of the moving distance of the stretch film when packaging the wrapped product. After the detection electric eye 14 can no longer detect the product, the disc motor 4 will stop rotating, and then the stretch film can be cut off and stuffed into the product. As the stretch film is cut off, the positioning torsion spring 12 will push the rotating discharge arm 11 to reset, so as to complete the packaging of the product, which is convenient for packaging products of different heights and automatically stops.

[0035] A platform plate 5 is fixedly mounted on the output end of the disc motor 4 , and the platform plate 5 and the disc motor 4 are concentrically designed, with a bearing provided between the platform plate 5 and the frame 1 .

[0036] The bearings provided in the frame 1 can enable the platform plate 5 to bear a greater weight, and can make the platform plate 5 rotate more smoothly when the disc motor 4 rotates to drive the platform plate 5 to rotate.

[0037] The outer surface of the frame 1 is provided with marking lines 6, and the marking lines 6 are in contact with the ground. A tank chain is provided between the load-bearing platform 10 and the frame 1, and through holes are provided on the outer surfaces of the frame 1 and the control box 18.

[0038] When placing the product on the platform board 5 by a forklift, the marking line 6 can limit and guide the forklift to enter the marking line 6 at the correct position, so that the product can be accurately placed in the center of the platform board 5. The tank chain set between the load-bearing platform 10 and the frame 1 can effectively protect the circuits of the pressure relay 13 and the detection electric eye 14, and can be connected to the control box 18 through the through holes on the outer surface of the frame 1 and the control box 18, reducing the risk of circuit entanglement and breakage.

[0039] An imaging device 16 is provided on one side of the frame 1 and is placed on the ground. An imaging screen 17 is fixedly mounted on the side surface of one end of the frame 1 close to the control box 18 .

[0040] The image of the product when it is placed can be projected onto the display screen 17 through the imaging device 16, which makes it easier for the forklift to find the correct position when placing the product, ensuring the concentricity of the product and the platform plate 5. This makes it unnecessary to get off the forklift to check when operating the forklift, thereby improving the efficiency and accuracy of product placement and reducing the unstable packaging pressure caused by eccentricity when the product is rotated.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
