Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a double-roller synchronous shot blasting machine for plant gum. Background Technology

[0002] Plant gums, as natural polymers, are widely used in various fields due to their excellent thickening, stabilizing, and emulsifying properties. During the production process, plant gums are typically processed into granules for ease of storage, transportation, and use.

[0003] However, in actual production, existing double-roll shot blasting machines specifically designed for plant-based gums require stopping the machine to unload material once the receiving hopper is full. Specifically, as the pressure rollers continuously compress the material and allow it to fall into the receiving hopper below, once the hopper is full, the operator must pause the entire shot blasting machine, remove the full hopper, replace it with an empty one, and only then can the machine be restarted. This process interrupts continuous production and reduces overall production efficiency. Utility Model Content

A rack is fixedly provided on the bottom surface of the movable plate, and a first gear is fixedly sleeved on the outer periphery of the transmission cylinder. The rack meshes with the first gear to drive the transmission cylinder and the rotating bar to rotate synchronously, thereby driving the round pin, the slider, the baffle, and the receiving shell to move laterally.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a double-roller synchronous shot blasting machine specifically for plant-based adhesives.

[0024] Reference Figures 1-2 A double-roller synchronous shot press for plant gum includes a storage shell 1 and shot press rollers 3. The two shot press rollers 3 are arranged in the inner cavity of the storage shell 1 from left to right, and the two shot press rollers 3 are arranged in pairs. The circumferential surface of the shot press rollers 3 is provided with hemispherical concave holes. When the hemispherical concave holes on the two shot press rollers 3 are matched and interlocked, they can be squeezed to form granular (spherical) plant gum.

[0025] Reference Figures 1-2 A rotating shaft 2 is fixedly inserted into the middle of the shot-pressing roller 3. Both ends of the rotating shaft 2 are rotatably connected to the inner wall of the storage shell 1 (e.g., via bearings). A first motor is fixedly installed on the outer wall of the storage shell 1 at a position corresponding to the rotating shaft 2. The output end of the first motor is coaxial with and fixedly connected to one end of the rotating shaft 2 (e.g., via a coupling). The first motor can only drive a single shot-pressing roller 3 to rotate. In order to make the two shot-pressing rollers 3 rotate synchronously (at the same speed, in opposite directions, simultaneously), a first gear needs to be fixedly fitted at the same end of the two rotating shafts 2. The two first gears mesh with each other and the transmission ratio is 1:1, thereby achieving synchronous transmission.

[0026] Reference Figure 2 and Figure 5 The storage shell 1 has a horizontally opened through groove at its lower end, which is open at both ends. A receiving shell 19 is inserted into the through groove and can slide back and forth along the length of the through groove. The receiving shell 19 has two receiving cavities with open tops. A partition 13 is fixedly installed in the middle of the inner cavity of the receiving shell 19, and the two receiving cavities are located on both sides of the partition 13.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The receiving shell 19 has baffles 7 on the outer sides of its two end plates. During the lateral movement of the baffles 7, the receiving shell 19 can be pushed to move laterally (at the same speed, in the same direction, and simultaneously). The side wall of the receiving shell 19 is provided with a first transmission mechanism that drives the two baffles 7 to move.

[0028] Reference Figures 1-3The first transmission mechanism includes a slider 17 and a slide rod 6. The slide rod 6 is laterally disposed between two baffles 7, and both ends of the same slide rod 6 are vertically fixedly connected to the two baffles 7 respectively (e.g., by bolts). Slide rods 6 are fixedly disposed between both ends of the two baffles 7. The two slide rods 6 are arranged parallel to each other, and the two baffles 7 are both vertically disposed and parallel to each other, forming a rectangular connection between the two slide rods 6 and the two baffles 7.

[0029] Reference Figures 2-3 A fixed block 5 is movably sleeved on the wall of the sliding rod 6, allowing the sliding rod 6 to move along the inner cavity of the fixed block 5. One side of the fixed block 5 is fixedly connected to the outer wall of the storage shell 1 (e.g., by bolts). The slider 17 is fixedly sleeved on the middle of the outer surface of the sliding rod. A transmission cylinder 14 is rotatably mounted on both outer walls of the storage shell 1. The transmission cylinder 14 is horizontally positioned with its axis perpendicular to the outer wall of the storage shell 1. A rotating bar 20 is vertically fixedly connected to the end of the transmission cylinder 14, and the end of the rotating bar 20 is connected to the end of the transmission cylinder 14. The rotating bar 20 can rotate around the transmission cylinder 14, thereby actuating the slider 17 to move horizontally, which in turn drives the receiving shell 19 to move horizontally. A strip-shaped hole is provided on the side wall of the rotating bar 20. A round pin 18 is fixedly mounted on the side of the slider 17 near the rotating bar. The round pin 18 is inserted into the strip-shaped hole and can slide along the length direction of the strip-shaped hole. The length direction of the strip-shaped hole is along the length direction of the rotating bar 20.

[0030] Reference Figure 4 A horizontally positioned support shaft 21 (e.g., connected by bolts) is fixedly installed on the outer wall of the storage shell 1. The support shaft 21 is arranged horizontally. The transmission cylinder 14 is rotatably sleeved on the outer circumference of the support shaft 21 (e.g., connected by bearings). A retaining ring 211 (e.g., fixedly connected by an integral structure) is fixedly installed on the circumferential surface of one end of the support shaft 21. A limiting plate 212 (e.g., detachably connected by bolts) is detachably installed on the other end of the support shaft 21. The retaining ring 211 is located on the side of the first gear 15 away from the transmission cylinder 14, and the limiting plate 212 is located on the side of the transmission cylinder 14 away from the first gear 15, thereby clamping the first gear 15 and the transmission cylinder 14 and preventing the first gear 15 and the transmission cylinder 14 from falling off the support shaft 21.

[0031] Reference Figure 4 The transmission cylinder 14 and the first gear 15 are coaxially arranged, and the end face of the first gear 15 is fixedly connected to the end face of the transmission cylinder 14 (for example, by bolts), thereby transmitting torque.

[0032] Reference Figure 3 An anti-slip ring 4 is fixedly sleeved at the end of the round pin 18 away from the slider 17, effectively preventing the round pin 18 from slipping out of the strip hole. The slider 17 and the anti-slip ring 4 respectively abut against the two side walls of the rotating bar 20.

[0033] The rod wall of the round pin 18 and the inner wall of the strip hole are coated with a wear-resistant coating (such as a ceramic coating) to improve the wear resistance of the round pin 18 and the inner wall of the strip hole and slow down the wear rate. The outer wall of the storage shell 1 away from the first motor is provided with a second transmission mechanism to drive the transmission cylinder 14 to rotate.

[0034] Reference Figures 1-2 The second transmission mechanism includes a linear actuator 9 and a movable plate 8. The linear actuator 9 is fixedly mounted on the side of the storage shell 1 away from the first motor. One end of the linear actuator 9 is connected to the outer wall of the storage shell 1, and the other end is connected to the horizontal plate 12. The end of the piston rod of the linear actuator 9 away from the outer shell is vertically and fixedly connected to the horizontal plate 12. The end of the outer shell of the linear actuator 9 away from the piston rod is vertically and fixedly connected to the outer wall of the storage shell 1. Movable plates 8 are fixedly mounted on both ends of the side of the horizontal plate 12 near the receiving shell 19. A rack 16 is fixedly mounted on the lower side of the movable plate 8. A first gear 15 is fixedly sleeved on the rod wall of the transmission cylinder 14. The rack 16 meshes with the first gear 15. The meshing of the rack 16 and the gear 15 drives the transmission cylinder 14 and the rotating bar 20 to rotate synchronously, thereby driving the round pin 18, the slider 17, the baffle 7, and the receiving shell 19 to move laterally.

[0035] The horizontal plate 12 is positioned above the end opening of the through groove to avoid obstructing the through groove.

[0036] The side edge of the horizontal plate 12 is perpendicularly and fixedly connected to the side edge of the movable plate 8 (e.g., by bolts); under the drive of the linear actuator 9, the horizontal plate 12 and the movable plate 8 move synchronously (at the same speed, in the same direction, and simultaneously).

[0037] A telescopic rod is provided on the outer wall of the storage shell 1 and next to the linear actuator 9. The telescopic rod includes a guide post 11 and a guide sleeve 10. One end of the guide post is inserted into the inner cavity of the guide sleeve 10 and the other end is perpendicularly connected to the horizontal plate 12. The end of the guide sleeve 10 away from the guide post 11 is perpendicularly fixedly connected to the outer wall of the storage shell 1. The telescopic rod is used to drive the horizontal plate 12 to move stably.

[0038] Reference Figure 5The receiving shell 19 has openings 191 at the bottom of its two end plates, which can be opened and closed. Door panels are installed at these openings, with the top of the door panels hinged to the receiving shell 19 and the bottom detachably connected to it (e.g., via spring clips). The two openings 191 communicate with two receiving chambers. The door panels are opened and closed manually. The bottom of each receiving chamber has a discharge surface that slopes downwards towards the openings 191; when the door panels are opened, the plant glue in the receiving chambers passes through the openings 191 and rolls into the transport vehicle 22 below. A baffle 7 is located above the door panels to prevent obstruction and allow for smooth opening.

[0039] Reference Figure 5 When a receiving chamber is located directly below the shot roller 3 (for receiving materials), the opening 191 connected to the receiving chamber is closed (i.e., the door panel inside the opening 191 is fastened to prevent plant glue from rolling out). The other receiving chamber is located outside the storage shell 1 and is used for discharging materials (i.e., the opening 191 connected to the receiving chamber is open, i.e., the door panel inside the opening 191 is open).

[0040] Reference Figure 5 The storage shell 1 is pressed and placed on the support frame 23, which is pressed against the floor of the workshop, thereby raising the height of the receiving shell 19 so that it can be positioned above the transport vehicle 22. Transport vehicles 22 can be parked on both sides of the support frame 23. When one transport vehicle 22 receives material (e.g., the transport vehicle 22 on the right), another transport vehicle 22 can drive away (e.g., the transport vehicle 22 on the left), and then a new transport vehicle 22 will park, waiting to receive material, thus achieving a continuous cycle of material receiving without stopping the machine.

[0041] Reference Figure 1 The movable plate 8 is connected to the storage shell 1 via a horizontally arranged ball linear guide pair, thereby improving the movement stability of the movable plate 8. The guide rail of the ball linear guide pair is fixedly connected to the outer wall of the storage shell 1 by bolts, and the slider of the ball linear guide pair is fixedly connected to the movable plate 8 by bolts.

[0042] Linear actuators are electric actuators, pneumatic actuators, hydraulic actuators, or combinations thereof (e.g., electro-hydraulic actuators). When a linear actuator uses a hydraulic cylinder within a hydraulic actuator, the hydraulic cylinder is connected to an external oil pump via an oil pipe, and the external oil pump is connected to an external oil tank. A second motor is installed in the oil pump to drive the impeller within the pump.

[0043] This utility model also includes an electrical cabinet, which is fixedly installed on the workshop floor by bolts; the first motor and the linear driver are connected to the electrical cabinet by wires and signal lines; the electrical cabinet is connected to the external power supply and the external controller (such as a computer or PLC programmable logic controller) by wires and signal lines respectively, and the external controller controls the start and stop and other working states of the first motor and the linear driver in this utility model through the electrical cabinet.

[0044] Both the first and second motors are controllable motors (such as servo motors or stepper motors). By inputting electrical signals to the controllable motors through an external controller, the speed, number of revolutions per rotation, angle of rotation per rotation, and start / stop timing of the controllable motors can be controlled.

[0045] In this invention, a first motor drives a rotating shaft 2 to rotate a shot-pressing roller 3, pressing plant gum material into granules that fall into a receiving shell 19. When one receiving chamber is nearly full, a linear actuator 9 is activated, causing a piston rod to push a horizontal plate 12 to move. A movable plate 8 drives a rack 16 to mesh with a first gear 15, causing the transmission cylinder 14 to rotate and thus move the round pin 18, slider 17, and receiving shell 19 laterally, allowing another empty receiving chamber to move below the shot-pressing roller 3 to receive material. Simultaneously, material can be unloaded from the external full space, enabling continuous production without stopping the machine and improving efficiency.

[0046] In conventional technology, a linear actuator 9 is usually used to directly connect to the receiving shell 19 and drive it to move laterally. However, this type of technology requires a linear actuator 9 with a large stroke. In this patent, a lever arm structure is formed by using a rotating bar. Only a short displacement of the rack 16 is needed to drive the first gear 15 to rotate at a sufficient angle, thereby enabling the receiving shell 19 to achieve a large lateral displacement. Therefore, the linear actuator 9 only needs a small amount of extension (i.e., stroke) to achieve this.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
