Description

Technical Field

[0001] This utility model belongs to the field of baling machine technology, specifically relating to an automatic steel strapping machine for irregularly shaped tubes. Background Technology

[0002] The automatic steel strapping machine for irregularly shaped pipes is a specialized device for automatically packaging irregularly shaped pipes (such as various bends and other irregularly shaped tubing). It is primarily used for bundling steel pipes, metal tubing, and other pipes of different shapes. By using steel strapping, the safety of pipe stacking and transportation is improved, preventing the pipes from scattering and ensuring they are not damaged during transport and storage.

[0003] Problems with existing technology:

[0004] Existing automatic steel strapping machines often use the machine to pull the steel strapping during packaging. When the steel strapping contracts to the machine's torque limit, clamping pliers are used to tighten the strapping buckle until it deforms, achieving a firm fusion. This method is efficient and produces tight packaging. However, when packaging irregularly shaped tubes, which often have protrusions and indentations, the above method can easily cause deformation of protruding parts of the tubes if the machine's torque is too high, or insufficient torque results in an inadequate package. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic steel strapping machine for shaped tubes. Through the design of the tension judgment head, it can judge the tension on the excess steel strap during the process of the head pressing against the steel strap buckle and pulling the excess steel strap. Then, the upper limit of the tension on the excess steel strap is controlled by the force limiting component to prevent excessive pressure inside the steel strap ring from damaging the shaped tube. This allows for accurate control of the tension on the excess steel strap each time the shaped tube is packed, thereby controlling the pressure inside the steel strap ring.

[0008] The motor block has a winding wheel inside, which contacts the excess steel strip. The tension judging head has a sliding abutment inside, which contacts the steel strip buckle. A measuring spring is fixedly installed between the abutment and the inner wall of the tension judging head. A force limiting component is provided on the top of the tension judging head.

[0009] The adjusting sliding slot is internally vertically arrayed with a plurality of limiting slots, and the limiting force assembly is slidingly installed in the adjusting sliding slot.

[0010] The weak current pin is fixedly installed at the bottom of the limiting force assembly corresponding to the resisting head.

[0011] The limiting force assembly comprises a limiting force column, limiting plates are rotationally connected to both sides of the limiting force column corresponding to the limiting slots, a moving knob is vertically slidingly installed in the limiting force column, a connecting plate is fixedly installed at the bottom of the moving knob corresponding to the limiting plate, the connecting plate is rotationally connected to the limiting plate, a return spring is fixedly connected to the bottom of the inside of the moving knob and the limiting force column, a sliding support plate is fixedly connected to the outside of the limiting force column, and the sliding support plate is slidingly installed in the adjusting sliding slot.

DETAILED DESCRIPTION

[0024] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically explained below in combination with examples. It should be understood that the following text is only used to describe one or several specific implementation manners of the utility model, and does not strictly limit the protection scope of the utility model specifically requested.

[0025] As Figs. 1-3 shown, an automatic steel band packing machine for special-shaped pipes comprises a handle 6, one end of the handle 6 is provided with a motor block 3, one side of the motor block 3 is provided with a tension judgment head 9, one side of the tension judgment head 9 is provided with a steel band buckle 2, the inside of the steel band buckle 2 is provided with a steel band ring 1 and an excess steel band 8, one end of the excess steel band 8 extends to the inside of the bottom end of the tension judgment head 9 and the motor block 3; the other end of the handle 6 is provided with a dismounting power supply 5, one side of the handle 6 is provided with a clever plate 4, the clever plate 4 extends to the inside of the motor block 3 and is connected with a winding wheel 7; the inside of the motor block 3 is provided with the winding wheel 7, the winding wheel 7 is in contact with the excess steel band 8, the inside of the tension judgment head 9 is slidably provided with an abutting head 901, the abutting head 901 is in contact with the steel band buckle 2.

[0026] When the steel band packing for special-shaped pipes is carried out, first, the steel band ring 1 is wound around the special-shaped pipe bundle, then, the steel band buckle 2 is passed through to form a steel ring to bundle the special-shaped pipe bundle, the excess part is the excess steel band 8, at this time, the clever plate 4 is pressed to lift the winding wheel 7, then, the excess steel band 8 is placed at the bottom of the motor block 3, the excess steel band 8 is clamped by the motor block 3 and the winding wheel 7, under the driving of the motor, the winding wheel 7 rotates to pull the excess steel band 8, first, when the packing machine pulls the excess steel band 8, the packing machine gradually approaches the steel band buckle 2, when the tension judgment head 9 abuts against the steel band buckle 2, the packing machine no longer moves, the excess steel band 8 continues to be pulled, the steel band ring 1 gradually shrinks, at this time, the pressure in the inside of the steel band ring 1 becomes larger and larger.

[0027] Referring to the drawings Figs. 3-5The measuring spring 902 is fixedly installed between the head 901 and the inner wall of the tension judging head 9, and the tension judging head 9 is provided with a tension limiting assembly 910 at the top. The tension judging head 9 is provided with an adjusting sliding groove 904 at a position corresponding to the tension limiting assembly 910, and a plurality of limiting slots 905 are vertically arranged in the adjusting sliding groove 904. The tension limiting assembly 910 is slidingly installed in the adjusting sliding groove 904. The weak current pin 903 is fixedly installed at a position corresponding to the bottom of the tension limiting assembly 910, and the bottom of the tension limiting assembly 910 is provided with an electric brush.

[0028] According to the above structure, when the head 901 abuts against the steel band buckle 2, the excess steel band 8 is continuously pulled under the action of the winding wheel 7. When the steel band ring 1 is reduced to a certain extent, the internal pressure gradually increases, and the pressure on the special-shaped pipe bundle also gradually increases. When the steel band buckle 2 is stationary, the pressure on the special-shaped pipe bundle in the steel band ring 1 is proportional to the tension of the excess steel band 8. With the gradual increase of the internal pressure of the steel band ring 1, the reaction force of the excess steel band 8 on the winding wheel 7 pushes the winding wheel 7 towards the steel band buckle 2. At this time, one end of the head 901 is abutted against the steel band buckle 2, and the other end is subjected to the forward pushing force transmitted by the winding wheel 7. At this time, the measuring spring 902 is compressed and shortened, and the head 901 is in a stationary state. The other parts of the packing machine move towards the head 901 until the weak current pin 903 contacts the electric brush to send an electric signal to stop the rotation of the winding wheel 7. At this time, the packing machine stops working.

[0029] Referring to the drawings Figs. 4-6 The tension limiting assembly 910 comprises a tension limiting column 912, and the limiting slots 905 are rotatably connected to the limiting plates 913 at positions corresponding to the two sides of the tension limiting column 912. The inside of the tension limiting column 912 is vertically slidingly installed with a moving button 911. The moving button 911 is fixedly installed with a connecting plate 916 at a position corresponding to the bottom of the limiting plate 913. The connecting plate 916 is rotatably connected to the limiting plate 913. The moving button 911 is fixedly connected to the inside bottom of the tension limiting column 912 with a return spring 915. The outside of the tension limiting column 912 is fixedly connected with a sliding support plate 914, and the sliding support plate 914 is slidingly installed in the adjusting sliding groove 904.

[0030] According to the above structure, by changing the position of the sliding limiting force assembly 910, since the elastic force of the spring is proportional to the shortening amount, the closer the limiting force assembly 910 is to the abutting head 901, the smaller the winding wheel 7 pushing force required for the weak electric pin 903 to contact the brush, and the smaller the pressure inside the steel band ring 1, and vice versa, the farther the limiting force assembly 910 is from the abutting head 901, the greater the winding measuring spring 902 needs to be compressed, and the greater the pressure inside the steel band ring 1, when it is necessary to adjust the position of the limiting force assembly 910, only need to press the moving button 911 to make it push the limiting plate 913 to rotate, and then the limiting plate 913 enters the inside of the limiting force column 912, so that the limiting plate 913 and the limiting slot 905 are inserted and separated, and the limiting force assembly 910 can be moved, so as to control the pressure inside the steel band ring 1 of the packing machine during packaging, when the limiting force assembly 910 reaches the predetermined position, release the moving button 911, the limiting plate 913 will be reset under the action of the reset spring 915, and the limiting plate 913 and the limiting slot 905 are inserted to limit the limiting force assembly 910.

[0031] The working principle of the utility model is: the steel band ring 1 is wound around the special-shaped pipe bundle, then passes through the steel band buckle 2 to form a steel ring to bundle the special-shaped pipe bundle, the excess part is the excess steel band 8, at this time, press the clever plate 4 to lift the winding wheel 7, then place the excess steel band 8 at the bottom of the motor block 3, clamp the excess steel band 8 through the motor block 3 and the winding wheel 7, rotate the winding wheel 7 under the drive of the motor to pull the excess steel band 8, first, when the packing machine pulls the excess steel band 8, the packing machine gradually approaches the steel band buckle 2, when the tension judgment head 9 abuts against the steel band buckle 2, the packing machine stops moving, the excess steel band 8 continues to be pulled, and the steel band ring 1 gradually shrinks, at this time, the pressure inside the steel band ring 1 becomes larger and larger.

[0032] The above is only the preferred embodiment of the utility model, it should be pointed out that for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the art, unless otherwise specified and limited.
