[0002] Plastic granules are granular products obtained by melting, extruding, cooling and cutting plastic raw materials. They are often used to make various plastic products through a variety of processing methods.

[0003] The automatic feeding device for plastic pellets is an automated system used to transport plastic pellets from storage containers to processing equipment such as hot melt tanks, extruders, and injection molding machines.

[0004] For example, the patent publication number is CN107973140B and the publication date is 2020.04.24, which discloses an automatic feeding device for granular materials. The automatic feeding device drives the cylinder connecting seat and the rack connecting seat to be connected into one by a first cylinder, so that the hopper can be driven by the cylinder to move to the bottom of the material box to receive the material, and then the cylinder drives the hopper to move to the unloading position. At this time, the first cylinder drives the cylinder connecting seat and the rack connecting seat to separate, and the hopper no longer moves with the drive of the cylinder. The cylinder drives the rack to move and mesh with the gear, so that the hopper can pour out the material. Not only is the structure complicated, it needs to repeatedly drive the first cylinder and the cylinder to cooperate to realize the feeding and pouring operations of the hopper, and it can only feed horizontally, and cannot feed vertically or tilted.

Therefore, they cannot be understood as limitations on the present invention.

[0027] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] A plastic granule automatic feeding device, such as Figure 1-Figure 3 As shown, it includes two mounting plates 1, a linear guide module 2 is arranged between the two mounting plates 1, a slide support module 3 is slid on the linear guide module 2, the slide support module 3 is driven by the linear guide module 2 to move between the two mounting plates 1, a support shaft 41 is rotatably arranged on the slide support module 3, and a barrel 42 for loading plastic particles is connected to the left end of the support shaft 41, so that the two mounting plates 1 are installed in a vertical arrangement (such as Figure 1 ), at this time, the linear guide module 2 is controlled to drive the slide support module 3 to drive the barrel 42 to move vertically along the linear guide module 2 through the support shaft 41, so as to vertically transport the plastic particles from a low place to a high place, which is convenient for transporting the plastic particles to higher processing equipment. The barrel 42 has a state of loading plastic particles with the opening facing upward, and the barrel 42 also has a state of pouring plastic particles with the opening facing downward. A driven gear 1 43 is connected to the support shaft 41, and a driving motor 1 is installed on one side of the slide support module 3. The output shaft of the driving motor 1 is connected to a driving gear 1 meshing with the driven gear 1 43. 44. When loading plastic particles, the opening of the barrel 42 faces upward. When the plastic particles in the barrel 42 need to be poured out, the driving motor is controlled to drive the driving gear 44 to rotate and engage with the driven gear 43. The driven gear 43 will drive the barrel 42 to rotate through the support shaft 41, so that the opening of the barrel 42 faces downward and gradually pours out the plastic particles, thereby completing the automatic feeding of the plastic particles. If the barrel 42 is located between two processing equipment, regardless of whether the heights are the same, rotating the barrel 42 in different directions can also feed the two processing equipment separately, and the feeding flexibility is high.

[0029] In another use mode of the feeding device, the two mounting plates 1 can be installed in a horizontal arrangement (such as Figure 7), at this time, the driving motor is used to drive the active gear 44 to rotate and engage with the driven gear 43, so that the driven gear 43 drives the barrel 42 to rotate through the support shaft 41 until the opening faces upward, and the plastic particles can be loaded normally. In this way, through the engagement of the active gear 44 and the driven gear 43, the barrel 42 can be used to pour out the plastic particles and the opening direction of the barrel 42 can be corrected. At this time, the linear guide module 2 is controlled to drive the slide support module 3 to drive the barrel 42 to move horizontally along the linear guide module 2 through the support shaft 41, thereby transporting the plastic particles from the storage container to the processing equipment in a horizontal position, and the usage is diversified.

[0030] Similarly, the two mounting plates 1 can also be installed in an inclined arrangement (such as Figure 8 ), and use a driving motor to drive a driving gear 44 to rotate and engage with a driven gear 43, so that the driven gear 43 drives the barrel 42 to rotate through the support shaft 41 until the opening faces upward and it can be used normally. No further details will be given here.

[0031] The feeding device has a simple structure and can overcome the limitations and shortcomings of the existing feeding device only by changing the installation method. In the process of the barrel 42 moving between the two mounting plates 1, the driving motor can be controlled at any time to drive the driving gear 44 to rotate the barrel 42 to pour out the plastic particles. When the linear guide module 2 spans across multiple processing equipment, it is convenient to feed multiple processing equipment in sequence, and can be suitable for different forms of automated feeding.

[0032] like Figure 2 and Figure 3 As shown, the linear guide module 2 includes two guide rods 21, the two guide rods 21 are connected between the two mounting plates 1, the slide support module 3 is slidably matched with the guide rods 21, and a screw rod 22 is rotatably arranged between the two mounting plates 1. The slide support module 3 is threadedly matched with the screw rod 22. The rotation of the screw rod 22 will drive the slide support module 3 to move between the two mounting plates 1 along the guide rod 21, so that the slide support module 3 drives the barrel 42 to move through the support shaft 41, and the self-locking of the thread on the screw rod 22 can prevent the slide support module 3 from sliding randomly, thereby improving the stability of the barrel 42, the lower end of the screw rod 22 is connected with a driven gear 23, and a servo motor 1 24 is installed on the lower mounting plate 1, and a driving gear 25 meshing with the driven gear 23 is connected to the output shaft of the servo motor 1 24, and the servo motor 1 24 is controlled to drive the driving gear 25 to rotate and mesh with the driven gear 23, and the driven gear 23 will drive the screw rod 22 to rotate, thereby completing the driving of the screw rod 22.

[0033] like Figure 2 and Figure 3As shown, the slide support module 3 includes a nut sleeve 31 sliding between two guide rods 21, the nut sleeve 31 is threadedly connected to the screw rod 22, a support sleeve 32 is provided on the nut sleeve 31, a support shaft 41 is rotatably arranged on one side of the support sleeve 32, a drive motor is installed on one side of the support sleeve 32, and the rotation of the screw rod 22 will drive the nut sleeve 31 to move along the guide rod 21, and the nut sleeve 31 will drive the barrel 42 to move through the support shaft 41.

[0034] like Figure 2 and Figure 3 As shown, the slide support module 3 also includes a gear ring 33 connected to the upper side of the support sleeve 32, the support sleeve 32 is rotatably arranged on the nut sleeve 31, and a driving motor 2 is installed on the upper side of the nut sleeve 31. A spur gear 34 meshing with the gear ring 33 is connected to the output shaft of the driving motor 2. If it is necessary to further adjust the position of the barrel 42 pouring out the plastic particles, after the barrel 42 is loaded with the plastic particles and moves up, the driving motor 2 is controlled to drive the spur gear 34 to rotate and mesh with the gear ring 33, so that the gear ring 33 drives the support sleeve 32 to rotate, and the support sleeve 32 will be driven by the support shaft 41 The movable barrel 42 and the driven gear 43 revolve around the nut sleeve 31 as the center to adjust the position of the barrel 42. At the same time, the support sleeve 32 will also drive the driving gear 44 to revolve through the driving motor 1, thereby maintaining the meshing position of the driving gear 44 and the driven gear 43. When it is necessary to pour out the plastic particles, the driving motor 1 is controlled to drive the driving gear 44 to rotate and mesh with the driven gear 43. In this way, the position of the barrel 42 for pouring out the plastic particles can be conveniently adjusted, and the barrel 42 can be used for feeding operations of two adjacent processing equipment.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a cover plate 52 suitable for covering the opening of the barrel 42. When the barrel 42 needs to load or pour out plastic particles, the cover plate 52 is opened. In the process of transporting plastic particles, the cover plate 52 can be closed, and the driving motor is controlled to drive the driving gear 44 to swing back and forth and engage with the driven gear 43, so that the driven gear 43 drives the barrel 42 to swing back and forth through the support shaft 41. In this way, when loading a variety of different plastic particles, the plastic particles can be pre-mixed, and the cover plate 52 is driven to open and close by the opening and closing component, and the opening and closing component is arranged on the barrel 42.

[0036] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the opening and closing assembly includes a mounting seat 51 connected to the opening side of the barrel 42, a cover plate 52 is rotatably arranged on the mounting seat 51, a torsion spring 53 is connected between the cover plate 52 and the mounting seat 51, and the torsion spring 53 resets the cover plate 52 after the barrel 42 is rotated and opened.

Figure 6 As shown, when the cover 52 is in the closed state, the telescopic rod of the control electric push rod 61 is contracted, thereby driving the push rod 62 to squeeze the cover 52, and the torsion spring 53 is deformed, so that the cover 52 rotates open with the mounting seat 51 as the center. When the telescopic rod of the control electric push rod 61 is extended, the push rod 62 immediately releases the cover 52, and the cover 52 will rotate in the opposite direction and reset under the action of the torsion spring 53.

[0037] like Figure 5 , Figure 7 and Figure 8 As shown, it also includes a resistance rod 71 connected to the cover plate 52, and a servo motor 2 75 is installed on one of the two mounting plates 1. When the two mounting plates 1 are arranged vertically or tilted, the servo motor 2 75 is installed on the lower mounting plate 1, and when the two mounting plates 1 are arranged horizontally, the servo motor 2 75 is installed on the mounting plate 1 at the position where the barrel 42 is loaded with plastic particles. The output shaft of the servo motor 2 75 is connected to a support frame 72, and the support frame 72 is connected to an inclined rod 1 73 and an inclined rod 2 74 suitable for squeezing the resistance rod 71; when the barrel 42 is parallel to the linear guide module 2, the inclined rod 1 73 is suitable for squeezing the resistance rod 71, as shown in FIG. Figure 5 As shown, initially, the barrel 42 is in a position for loading plastic particles, the inclined rod 1 73 squeezes the contact rod 71, and the cover plate 52 is in an open state. When the barrel 42 is loaded with plastic particles and the cover plate 52 is driven upward by the mounting seat 51, the cover plate 52 will drive the contact rod 71 to gradually separate from the inclined rod 1 73, and the cover plate 52 will automatically reset under the action of the torsion spring 53; when the barrel 42 is perpendicular to the linear guide module 2, the inclined rod 2 74 is suitable for squeezing the contact rod 71, as shown in FIG. Figure 7As shown, initially, the barrel 42 is in the position for loading plastic particles, the inclined rod 2 74 squeezes the abutment rod 71, and the cover plate 52 is in the open state. When the barrel 42 is loaded with plastic particles and drives the cover plate 52 to move right through the mounting seat 51, the cover plate 52 will drive the abutment rod 71 to gradually disengage from the inclined rod 2 74, and the cover plate 52 will automatically reset under the action of the torsion spring 53; in this way, when it is necessary to load plastic particles, the cover plate 52 can be automatically opened by the action of the inclined rod 1 73 and the inclined rod 2 74, and the cover plate 52 can be automatically closed during the process of loading and transporting the plastic particles; in addition, when the two mounting plates 1 are installed in an inclined arrangement, the servo motor 2 75 is controlled to drive the support frame 72 to drive the inclined rod 1 73 and the inclined rod 2 74 to rotate, so that the inclined rod 2 74 still maintains contact and cooperation with the abutment rod 71, as shown in FIG. Figure 8 As shown, when the barrel 42 that needs to be loaded with plastic particles approaches the lower mounting plate 1, the resistance rod 71 is squeezed by the inclined rod 74, and the cover plate 52 opens. When the barrel 42 moves to the upper right, the resistance rod 71 will gradually disengage from the inclined rod 74, and the cover plate 52 will then reset and close under the action of the torsion spring 53. In this way, the cover plate 52 can be automatically opened and closed when the barrel 42 transports plastic particles in an inclined moving trajectory.

[0038] like Figure 6 As shown, the side of the barrel 42 relative to its opening is a bottom plate portion 421, and the bottom plate portion 421 of the barrel 42 slides on the inner side of the barrel 42, and the push rod 62 is connected to the bottom plate portion 421, so that when the telescopic rod of the electric push rod 61 is contracted and the push rod 62 pushes open the cover plate 52, the push rod 62 will also drive the bottom plate portion 421 of the barrel 42 to slide in the direction close to the opening of the barrel 42, and the bottom plate portion 421 will gradually push the plastic particles in the barrel 42 out of the opening of the barrel 42 during the sliding process, so that the plastic particles can be easily pushed out when the cover plate 52 is opened to pour out the plastic particles, thereby improving the efficiency of pouring out the plastic particles.
