Description

Technical Field

[0001] The utility model belongs to the technical field of industrial raw material bundling equipment, and in particular relates to a double-disc belt reel vehicle with a plastic-steel belt having a width of 10-19 mm. Background Art

[0002] All raw materials required for industrial manufacturing must undergo preliminary processing by upstream processing companies before being shipped to the corresponding enterprises. To facilitate transportation, raw materials, whether metal or non-metal, or in various forms such as pipes, plates, or blocks, often need to be stacked, bundled, and packaged before transportation to ensure safety and convenience. Therefore, material bundling equipment plays a vital role in ensuring transportation safety and efficiency.

[0003] Bundling equipment typically consists of a baler head, a threading mechanism, a reel, a stack rotation mechanism, and a control mechanism. The reel is the device that supplies the steel or plastic strap used for bundling. Driven by the baler head, it continuously feeds strap to the stack during bundling, ensuring smooth bundling. The reel typically features a reel on which the strap is wound. While the reel can hold a large amount of strap, premature release from a full reel during operation is detrimental to efficiency. If the threading speed is high, insufficient reel release or the strap jamming can easily lead to strap breakage, potentially creating a dangerous situation. Furthermore, since the reel is often fixed and lacks steering, an angle between the strapping mechanism and the reel's supply direction can easily cause the strap to wear during transport, leading to even jamming and breakage. Furthermore, due to a lack of monitoring equipment, reel machines often require manual inspection of strap usage, making it impossible to determine whether the strap has been consumed.

[0049] Figure 1 The figure schematically shows a front structural diagram of a double-disc plastic-steel belt reel vehicle in a preferred embodiment of the present invention. Figure 2 for Figure 1 The left view of the structure diagram. Figure 1 and Figure 2 As can be seen, in this preferred embodiment, the tape reel vehicle comprises three major components: a base 1, a tape accumulator 2, and a tape payout reel 3. The base 1 comprises a horizontally disposed base 11 and a plurality of fixing bolts 12 connected to the ground or other fixed surface. Two tape accumulators 2 and two tape payout reels 3 are fixed to the base 1, respectively. The two tape accumulators 2 are fixed side by side to one side of the base 1, while the two tape payout reels 3 are fixed to the base 1 in an alternating manner.

[0050] The tape accumulator 2 is fixedly connected to the base 1 at the bottom via a stand 21. A discharge guide wheel assembly 24 and an infeed guide wheel assembly 25 are fixed to the top of the stand 21. The discharge guide wheel assembly 24 and infeed guide wheel assembly 25 are located on either side of the top of the stand 21. The stand 21 houses a fixed pulley assembly 22 and a movable pulley assembly 23 for connecting and storing the plastic-steel tape. The fixed pulley assembly 22 is fixed to the top of the stand 21, while the movable pulley assembly 23 is movably mounted to the bottom of the fixed pulley assembly 22. To secure the movable pulley assembly 23 when the reel is stopped, a pin 27 is provided on one side of the stand 21. The stand 21 is also provided with a plurality of pin holes 27-1 arranged in pairs. When the pin 27 is inserted into the pin holes 27-1, it supports the movable pulley assembly 23. Furthermore, to limit the travel of the movable pulley assembly 23, four travel switches 28 are mounted on the stand 21 via vertically fixed channels 26. Among them, two are located at the upper part and are used to control the upper limit position of the movable pulley assembly 23, and the other two are located at the lower part and are used to control the lower limit position of the movable pulley assembly 23.

[0051] Each tape reel 3 comprises a reel frame 31, a power mechanism 32, and a reel body 33. The bottom of the reel frame 31 is fixedly connected to the base body 11 via bolts. The power mechanism 32 is a motor equipped with a speed reducer. The power mechanism 32 is fixedly connected to one side of the reel frame 31. The output shaft of the speed reducer passes through the top of the reel frame 31 and connects to the rotating shaft of the reel body 33. This allows the power mechanism 32 to drive the reel body 33 to rotate, thereby feeding the plastic-steel tape to the tape-consuming equipment.

[0052] Figure 3 The top view of a double-disc plastic-steel belt reel vehicle in a preferred embodiment of the present invention is schematically shown. Figure 3 It can be seen that in this preferred embodiment, in order to reduce the space occupied by the equipment, the two tape reels 3 are installed on the base 1 in a staggered manner. Since the width of the tape storage device 2 is relatively small, it is arranged in parallel on one side of the base 1. One tape storage device 2 is opposite to one tape reel 3 to facilitate the conveying of the plastic-steel tape. In addition, as can be seen from the figure, the tape outlet guide wheel assembly 24 and the tape inlet guide wheel assembly 25 are respectively fixed on both sides of the stand 21, wherein the tape inlet guide wheel assembly 25 faces the tape outlet reel 3, and the tape outlet guide wheel assembly 24 faces the tape-using device. It is worth noting that in order to detect whether the plastic-steel tape is used up, a sensor 25-1 is provided on the tape inlet guide wheel assembly 25 to monitor the situation of the tape reel 3 conveying the plastic-steel tape to the tape storage device 2, so that it can be quickly known when the plastic-steel tape is used up.

[0053] Figure 4 The three-dimensional structure diagram of a double-disc plastic-steel belt reel vehicle in a preferred embodiment of the present invention is schematically shown. Figure 4It can be seen that in this preferred embodiment, a controller 35 is fixed between the two reels 31 of the tape reel 3, and the controller 35 is connected to the power mechanism 32, thereby realizing the control of the power mechanism 32. Figure 4 As can be seen, the channel 26 is fixed to the side of the frame 21 facing the payout reel 3. Four travel switches 28 are mounted on it, two at the top and two at the bottom, respectively, to control the movement of the movable pulley assembly 23. Five parallel movable pulleys form a movable pulley block, connected in series by a shaft, with the two sides of the shaft connected by side panels. A slider 23-1 is located at each of the upper and lower ends of the side panels. These sliders 23-1 are positioned within the channel-steel columns, facilitating the up and down movement of the movable pulley block. Furthermore, cross plates fixedly connected to the side panels are located on the upper and lower sides of the movable pulley block, thus forming a single unit. The inlet guide pulley assembly 25 faces the payout reel 3 to facilitate the entry of the plastic-steel belt into the pulley block. The outlet guide pulley assembly 24 has a rotating shaft 24-1 located on the upper portion of its pulley frame. The rotating shaft 24-1 can drive the outlet guide pulley 360°, allowing the discharged plastic-steel belt to be directed to a belt-using device at any angle.

[0054] Figure 5 The top view of the double-disc plastic-steel belt reel vehicle base in a preferred embodiment of the present invention is schematically shown. Figure 5 As can be seen, in this preferred embodiment, the base 1 has an overall rectangular frame structure, divided into two sections by vertical and transverse channel steels for mounting the tape accumulator 2 and the tape payout reel 3. The section for mounting the tape accumulator 2, located on one side of the base 1, is primarily composed of two parallel channel steels, each provided with a plurality of stand mounting holes 11-1 for mounting the stand 11. The section of the base 1 for mounting the tape payout reel 3 has two staggered groups of eight (four in each group) rack mounting holes 11-2 for mounting the rack 31.

[0055] Figure 6 The following schematically shows a three-dimensional structural diagram of a double-disc plastic-steel belt reel storage device in a preferred embodiment of the present invention. Figure 6 As can be seen, in this preferred embodiment, the frame 21 is a rectangular frame structure consisting of a base plate 21-1, two columns 21-2, and a top plate 21-3. To enhance stability, triangular reinforcing ribs 21-4 are provided at the bottom between the base plate 21-1 and the columns 21-2. The columns 21-2 are channel steel, with the channels of the two columns 21-2 positioned relative to each other to accommodate the channel of the slider 23-1. Within the channels of the columns 21-2, there are two limit stops 21-5, one above and one below, to cushion and limit the movement of the movable pulley assembly 23.

[0056] Above the uprights 21-2, the fixed pulley assembly 22 includes a fixed pulley block 22-1 consisting of four pulleys arranged in parallel. A fixed vertical plate 22-2 connects the shaft of the fixed pulley block 22-1 to one side of the fixed pulley block 22-1. The upper end of the vertical plate 22-2 is fixed to the bottom of the top plate 21-3. A horizontal plate 22-3 is also installed between the top plate 21-3 and the fixed pulley block 22-1 to limit the range of motion of the plastic-steel belt during movement.

[0057] The movable pulley assembly 23 consists of five movable pulley groups 23-2 connected in parallel via shafts. A side plate 23-3 is connected to each end of the shaft of the movable pulley group 23-2. A slider 23-1 is fixed to each of the upper and lower ends of the side plates 23-3, forming the main body of the movable pulley assembly 23. To limit the range of motion of the plastic-steel belt during movement, cross plates are fixedly connected to the side plates 23-3 at the upper and lower ends of the movable pulley group 23-2.

[0058] The inlet guide wheel assembly 25 and outlet guide wheel assembly 24 are fixedly connected to the top plate 21-3 via angle steel II 25-2 and angle steel I 24-2, respectively, and extend to either side of the top plate 21-3. The free end of angle steel I 24-2 is rotatably connected to pulley frame I 24-3 via a rotating shaft 24-1. Pulley frame I 24-3 houses an outlet guide wheel 24-4. The bottom of the free end of angle steel II 25-2 is connected to pulley frame II 25-3, which also houses an inlet guide wheel 25-4. To monitor the usage of the plastic-steel belt, a sensor 25-1 is also installed on pulley frame II 25-3, allowing users to easily determine whether the plastic-steel belt has been used up.

[0059] Figure 7 The front view of the structure of the double-disc plastic-steel belt reel vehicle for unwinding the belt reel in a preferred embodiment of the present invention is schematically shown. Figure 7 As can be seen, in this preferred embodiment, the structure of the tape reel 3 of the reel vehicle is mainly composed of a reel frame 31, a power mechanism 32, a reel body 33, and a coupling 34. The bottom of the reel frame 31 is fixedly connected to the base 1 via bolts, and the power mechanism 32 is fixedly connected to one side of the reel frame 31. The power mechanism 32 is a motor with a reducer. The output shaft of the reducer is connected to the coupling 34 located at the top of the reel frame 31. The other end of the coupling 34 is connected to the rotating shaft of the reel body 33 to facilitate the transmission of power from the power mechanism 32 to the reel body 33. During use, the plastic steel belt is wrapped around the reel body 33. To save space, the two tape reels 3 mounted on the base 1 can be controlled by a single controller 35.

[0060] The technical principle and use process of the above-mentioned reel car are:

[0061] After the plastic-steel strapping tape is installed on the reel, the strapping head is passed through the inlet guide pulley and then introduced into the movable pulley assembly. It is then repeatedly wound around the movable and fixed pulleys before being guided out of the outlet guide pulley to the strapping equipment. The stored plastic-steel strap can be adjusted by adjusting the distance between the movable and fixed pulley assemblies. When baling begins, the stored plastic-steel strap is continuously consumed by the traction of the machine head, driving the movable pulley assembly upwards and decreasing the distance between them. When the movable pulley assembly reaches its limit, the power mechanism activates, causing the reel to rotate and release the plastic-steel strap toward the accumulator, and the movable pulley assembly begins to descend to store the strap. When the movable pulley assembly reaches its limit, the power mechanism stops, stopping the strapping.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
