Description

Technical Field

[0001] This invention relates to the field of ink preparation equipment, specifically to an ink stirring device. Background Technology

[0002] In the process of ink production and color matching, in order to achieve the required color and performance, it is often necessary to add a certain proportion of solid powder raw materials (such as pigment powder, auxiliary agent powder, etc.) to the liquid ink base for mixing. However, existing technologies generally adopt manual or semi-automatic feeding methods, that is, the solid raw materials are poured onto the liquid surface manually, or gravity feeding is carried out using a simple feeding structure.

[0003] In the aforementioned traditional methods, solid raw materials tend to float on the liquid surface and are difficult to wet quickly, leading to problems such as agglomeration, floating, or adhesion to the container walls, which in turn affects dispersion efficiency and mixing uniformity. To solve this problem, it is often necessary to extend the stirring time or introduce equipment with stronger shear force, which increases energy consumption and equipment costs, and also reduces process efficiency to some extent.

[0004] Furthermore, to achieve coordinated processing of raw material feeding and ink mixing, some equipment has attempted to introduce independent feeding power structures. However, these structures are typically complex, space-consuming, and have significant power redundancy, which is detrimental to the integration and lightweight development of the equipment. Meanwhile, in existing equipment, the feeding and mixing structures are independent, lacking a coupled and coordinated operation mechanism. This prevents them from simultaneously providing auxiliary mixing during the feeding process, and the overall operating efficiency still needs improvement.

[0005] Therefore, there is an urgent need to propose an integrated feeding and mixing structure that is simple in structure, can automatically settle materials, share power, and has the ability to disturb and mix, so as to solve the problems of insufficient material dispersion, redundant power configuration and low equipment integration in the existing technology.

[0006] Therefore, an ink stirring device is provided to address the above-mentioned problems. Summary of the Invention

[0007] In order to solve the problems of solid raw materials being easy to float and difficult to wet in existing ink feeding methods, resulting in agglomeration and adhesion, this invention provides an ink stirring device.

[0008] The present invention solves the above-mentioned technical problems through the following technical solutions: The present invention provides an ink stirring device, including a base and a support assembly fixed on the base. A drive assembly is connected to the top of the support assembly. The drive assembly is connected to the stirring part and drives the stirring part to rotate. The stirring part extends into the interior of a mixing tank. A discharge pipe is connected to the bottom side wall of the mixing tank, and a valve is provided on the discharge pipe. The mixing tank is equipped with a feeding component that can sink solid raw materials below the liquid surface. The feeding component and the stirring part are connected by a transmission component that has an auxiliary stirring function. The transmission assembly is located at the bottom of the inner cavity of the mixing tank; The stirring section includes a driving stirring rod connected to the driving assembly, and a transmission assembly is disposed on the surface of the driving stirring rod.

[0009] By using a feeding component that can submerge solid raw materials below the liquid surface, it is easy to fix the raw materials dissolved in the ink during stirring. The operation of the feeding component is powered by a drive component that drives the stirring, eliminating the need for an additional power source. At the same time, the transmission component used for transmission can also play an auxiliary role in stirring.

[0010] In this technical solution, the support component can be retractable or non-retractable. The support component includes a base, and a support rod is fixed on the top side wall of the base. The support rod is arranged vertically, and the top of the support rod is directly connected to the drive component or connected to the drive component through a lifting part.

[0011] When the support component is retractable, the extension and retraction of the support component drives the drive component to rise and fall, thereby adjusting the height of the stirring section.

[0012] The bottom of the mixing tank is equipped with multiple casters, preferably casters with a braking mechanism.

[0013] In this technical solution, the lifting part includes a vertically arranged lifting rod, which is extended and retracted by non-human power drive, and the top of the lifting rod is fixed to the drive assembly; One side of the lifting rod is provided with a retractable guide rod that is arranged vertically, and the top and bottom of the guide rod are respectively connected to the drive assembly and the extension plate at the top of the support rod.

[0014] The preferred type of lifting mast is a self-driven telescopic mast that is hydraulically driven, i.e., a hydraulic mast.

[0015] The hydraulic rod extends or retracts, causing the drive assembly to rise and fall.

[0016] The guide rod guides the extension and retraction of the lifting rod.

[0017] An outwardly extending limiting sleeve is fixed to the outer wall of the support rod, and the limiting sleeve fits against the outer wall of the mixing tank.

[0018] In this technical solution, the drive assembly includes a mounting shell, which is fixed to the top of the lifting rod. A drive motor is fixed inside the mounting shell, and a drive pulley is fixed to the output end of the drive motor. The drive pulley is connected to a driven pulley via a transmission belt. The driven pulley is mounted on the inner wall of the mounting shell. An extension rod connected to the stirring part is fixed at the center of the circular surface at the bottom of the driven pulley. The extension rod passes through the bottom side wall of the mounting shell and is arranged vertically.

[0019] The drive motor drives the drive pulley to rotate, which in turn drives the driven pulley to rotate via the transmission belt. The driven pulley then drives the extension rod, which is fixedly connected to it, to rotate, thereby causing the stirring section to rotate inside the mixing tank.

[0020] In this technical solution, the stirring part includes a driving stirring rod, the bottom end of which extends into the mixing tank and coincides with the central axis of the mixing tank; Multiple stirring blades are fixed to the bottom outer wall of the driving stirring rod.

[0021] The liquid raw materials of the ink are poured into the mixing tank, and then the drive assembly is started. The extension rod on the drive assembly drives the drive stirring rod to rotate, which in turn drives the stirring blades on the drive stirring rod to rotate, thus mixing the various raw materials of the ink.

[0022] In this technical solution, the transmission assembly includes an auxiliary stirring part and at least one transmission part, wherein the auxiliary stirring part is disposed on the driving stirring rod; The auxiliary stirring part and the transmission part are connected by a transmission, the transmission part and the feeding part are connected synchronously, and the feeding part is installed in the mixing tank; The feeding section is equipped with a feeding box for placing solid raw materials.

[0023] The auxiliary stirring unit and the driving stirring rod rotate synchronously. The rotating auxiliary stirring unit drives the feeding unit through the transmission unit, thus realizing the simultaneous driving of stirring and feeding through the driving component.

[0024] In this technical solution, the auxiliary stirring assembly includes a fixing collar, which is sleeved and fixed on the driving stirring rod. The annular surface of the fixing collar is fixed with a plurality of auxiliary mixing blades arranged in an annular array. The outer wall of the auxiliary mixing blades is fixed with driving rods arranged in a horizontal direction. The transmission unit is connected to the drive rods arranged in a ring array for mutual transmission and engagement.

[0025] In this technical solution, the driving stirring rod rotates, which in turn drives the fixed collar on its surface to rotate, thereby driving the auxiliary stirring blades on the fixed collar to rotate, thus playing an auxiliary stirring role.

[0026] In this technical solution, the transmission part includes a circular mounting plate, which is arranged vertically. A connecting shaft that can rotate on the inner wall of the mixing tank is fixed at the center of one of the circular surfaces of the mounting plate. The connecting shaft is mounted on the side wall of the mixing tank through a connecting column. Multiple transmission rods arranged in a circular array are fixed on the annular surface of the mounting plate. The transmission rods are arranged vertically, and the transmission rods arranged in a circular array mesh with the drive rods that are also arranged in a circular array. One end of the connecting shaft is provided with a feeding section; A stirring blade is fixed on the transmission rod.

[0027] The moving drive rod pushes the transmission rod to move in a circular trajectory, thereby causing the transmission rod to rotate. The transmission rod then drives the connecting disc connected to it to rotate, thus driving the feeding unit to run.

[0028] In this technical solution, the feeding part operates by rotating the connecting shaft, which drives the discharging box to reciprocate vertically within the mixing tank cavity; The feeding section is installed on the side wall of the mixing tank.

[0029] The feeding section drives the feeding box to move vertically, which means that the feeding box containing solid raw materials repeatedly enters below the liquid surface of the ink mixture. The material leakage hole allows the solid raw materials to come into contact with the liquid raw materials. At the same time, the feeding box is moving, which accelerates the dissolution of the solid raw materials into the liquid raw materials.

[0030] In this technical solution, the feeding part includes a lower pulley, which is sleeved and fixed on the connecting shaft. The lower pulley is connected to the self-rotating upper pulley via a conveyor belt. The upper pulley is installed on the top of the side wall of the mixing barrel by a fixing member. At least one material feeding box is fixed on the conveyor belt; The upper pulley is located on top of the lower pulley.

[0031] Specifically, the fastener has a "C" shaped structure and is fixed to the outer side wall of the mixing tank.

[0032] In this technical solution, the surface of the feeding box is provided with multiple material leakage holes, and the outer wall of the feeding box away from the conveyor belt is provided with a material discharge groove for placing solid raw materials. The two ends of the feeding box extend outward to form a symmetrical streamlined structure, and the area of ​​the feeding channel is less than half the area of ​​the side wall of the feeding box.

[0033] Solid raw materials are fed into the discharge box through the discharge channel.

[0034] In this technical solution, the surface of the material feeding channel is covered with a cover plate, the cover plate is slidably connected to the outer wall of the material feeding box, and a spring-loaded unit is provided at the sliding connection between the material feeding box and the cover plate. A triggering unit is provided on the top side of the feeding section, and the triggering unit pushes the cover plate to slide. The triggering unit includes a force transmission unit disposed on the cover plate, and the force transmission unit that moves synchronously with the feeding box overlaps with the limiting unit.

[0035] By covering the discharge chute with a cover plate, solid raw materials are prevented from directly detaching from the discharge box from the large discharge chute during movement, thus avoiding affecting the feeding effect of the feeding section.

[0036] In this technical solution, the force transmission unit is set on the eccentric side of the cover plate surface. The force transmission unit includes two symmetrically arranged connecting rods. The connecting rods are fixed on the cover plate. A connecting collar is fixed to the top of the connecting rod. The two connecting collars are respectively sleeved on both ends of the rotating horizontal axis. The rotating horizontal axis rotates inside the connecting collar. A driven push plate is fixed to the surface of the rotating horizontal axis between the two connecting collars; The limiting unit includes a drive plate that can be connected to the driven push plate. The drive plate is fixedly connected to the mounting cross plate via a fixing rod. The mounting cross plate is fixed to the mounting shell surface on the drive assembly. The drive plate is located on one side of the top of the upper pulley; A torsion spring is provided at the connection between the connecting collar and the rotating horizontal shaft, with the two ends of the torsion spring.

[0037] As the feeding box moves with the conveyor belt, the driven push plate in the eccentrically positioned force transmission unit first contacts the fixed drive plate and, under its push, causes the cover plate to slide, opening the feeding chute and allowing solid raw materials to be fed into the feeding box. At this point, the stirring speed can be appropriately reduced to facilitate feeding. As the feeding box continues to move, the cover plate slides to its limit position and stops moving forward. The torsion spring begins to deform under pressure, and the driven push plate then rotates and disengages from the drive plate. The cover plate and push plate automatically reset under the elastic force of the torsion spring, completing one feeding cycle. The sliding limit of the cover plate can be controlled by a limiting structure, specifically by using a length-limiting connecting rope or a travel-limiting telescopic rod.

[0038] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0039] The positive and progressive effects of this invention are as follows: This invention provides a feeding component that automatically sinks solid raw materials below the liquid surface, enabling solid powder raw materials to quickly come into contact with liquid ink during the addition process. This avoids the problems of floating, agglomeration, or uneven dispersion caused by the raw materials floating on the liquid surface and being difficult to wet during the traditional manual feeding process, thereby significantly improving the dissolution efficiency and mixing uniformity of solid raw materials.

[0040] Furthermore, the feeding component is powered by a drive assembly shared with the mixing unit, eliminating the need for an additional independent power source, simplifying the system structure, reducing overall manufacturing and maintenance costs, and improving the integration level of the equipment.

[0041] Furthermore, the transmission structure used to drive the feeding assembly can also agitate the ink during operation, thereby assisting in stirring, enhancing the internal flowability of the ink and the material exchange rate, and further improving the fusion effect and dispersion uniformity between ink components. The overall structural design is reasonable and has multiple technical advantages such as high-efficiency feeding, energy saving, and stirring assistance. Attached Figure Description

[0045] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0046] like Figure 1 As shown, an ink stirring device includes a base 1 and a support assembly 2 fixed on the base 1. A drive assembly 3 is connected to the top of the support assembly 2. The drive assembly 3 is connected to the stirring part and drives the stirring part to rotate. The stirring part extends into the mixing tank 4. A discharge pipe is connected to the bottom side wall of the mixing tank 4, and a valve is provided on the discharge pipe. The mixing tank 4 is equipped with a feeding component that can sink solid raw materials below the liquid surface. The feeding component and the stirring part are connected by a transmission component that has an auxiliary stirring function. The transmission assembly is located at the bottom of the inner cavity of the mixing tank; The stirring section includes a driving stirring rod 5 connected to the driving assembly 3, and a transmission assembly is provided on the surface of the driving stirring rod 5.

[0047] By using a feeding component that can submerge solid raw materials below the liquid surface, it is easy to fix the raw materials dissolved in the ink during stirring. The operation of the feeding component is powered by the drive component 3 used to drive the stirring, eliminating the need for an additional power source. At the same time, the transmission component used for transmission can also play an auxiliary role in stirring.

[0048] Example 1: As Figure 1 As shown, the support component 2 can be telescopic or non-telescopic. The support component 2 includes a base 1, and a support rod 21 is fixed on the top side wall of the base 1. The support rod 21 is arranged vertically, and the top of the support rod 21 is directly connected to the drive component 3 or connected to the drive component 3 through a lifting part.

[0049] When the support component 2 is retractable, the extension and retraction of the support component 2 drives the drive component 3 to rise and fall, thereby adjusting the height of the stirring part.

[0050] The bottom of the mixing tank 4 is equipped with multiple casters 41, preferably casters 41 with a braking structure.

[0051] Furthermore, the lifting unit includes a vertically arranged lifting rod 22, which is extended and retracted by non-human power drive, and the top of the lifting rod 22 is fixed to the drive assembly 3; A retractable guide rod 23 is provided on one side of the lifting rod 22, which is arranged vertically. The top and bottom of the guide rod 23 are respectively connected to the drive assembly 3 and the extension plate at the top of the support rod 21.

[0052] The lifting rod 22 is preferably a self-driven telescopic rod that is hydraulically driven, i.e., a hydraulic rod.

[0053] The hydraulic rod extends or retracts, causing the drive assembly 3 to rise or fall.

[0054] The guide rod guides the extension and retraction of the lifting rod 22.

[0055] A limiting sleeve 24 extending outward is fixed on the outer wall of the support rod 21, and the limiting sleeve 24 fits against the outer wall of the mixing tank 4.

[0056] Example 2: Figure 4 As shown, the drive assembly 3 includes a mounting shell 31, which is fixed to the top of the lifting rod 22. A drive motor 32 is fixed inside the cavity of the mounting shell 31. A drive pulley 33 is fixed to the output end of the drive motor 32. The drive pulley 33 is connected to a driven pulley 34 via a transmission belt 35. The driven pulley 34 is mounted on the inner wall of the mounting shell 31. An extension rod connected to the stirring part is fixed at the center of the circular surface at the bottom of the driven pulley 34. The extension rod passes through the bottom side wall of the mounting shell 31 and is arranged vertically.

[0057] The drive motor 32 drives the drive pulley 33 to rotate, and the drive pulley 33 drives the driven pulley 34 to rotate through the transmission belt 35. The driven pulley 34 drives the extension rod fixedly connected to it to rotate, thereby driving the stirring part to rotate inside the mixing tank 4.

[0058] The stirring unit includes a driving stirring rod 5, the bottom end of which extends into the mixing tank 4 and coincides with the central axis of the mixing tank 4; Multiple stirring blades 51 are fixed to the bottom outer wall of the drive stirring rod 5; The bottom end of the extension rod is fixedly connected to the drive stirring rod 5.

[0059] The liquid raw materials of the ink are poured into the mixing tank 4, and then the drive assembly 3 is started. The extension rod on the drive assembly 3 drives the drive stirring rod 5 to rotate, thereby driving the stirring blade 51 on the drive stirring rod 5 to rotate, mixing the various raw materials of the ink.

[0060] Example 3: Figures 10-12 As shown, the transmission assembly includes an auxiliary stirring part 6 and at least one transmission part 7, wherein the auxiliary stirring part 6 is disposed on the driving stirring rod 5; The auxiliary stirring part 6 and the transmission part 7 are connected by transmission, the transmission part 7 and the feeding part 8 are connected synchronously, and the feeding part 8 is installed in the mixing tank 4; The feeding section 8 is equipped with a feeding box 9 for placing solid raw materials.

[0061] The auxiliary stirring unit 6 and the driving stirring rod 5 rotate synchronously. The rotating auxiliary stirring unit 6 drives the feeding unit 8 through the transmission unit 7, thus realizing the simultaneous driving of stirring and feeding through the driving component 3.

[0062] The auxiliary stirring assembly includes a fixing collar 61, which is sleeved and fixed on the driving stirring rod 5. Multiple auxiliary mixing blades 62 arranged in a ring array are fixed on the annular surface of the fixing collar 61. Drive rods 63 distributed in a horizontal direction are fixed on the outer wall of the auxiliary mixing blades 62. The transmission unit 7 is connected to the drive rods 63 arranged in a ring array for mutual transmission and engagement.

[0063] The driving stirring rod 5 rotates, which in turn drives the fixed collar 61 on its surface to rotate, thereby driving the auxiliary stirring blades 51 on the fixed collar 61 to rotate, thus playing an auxiliary stirring role.

[0064] The drive rod 63, which is fixed on the auxiliary stirring blade 51, moves in a circular trajectory with the auxiliary stirring blade 51, and the moving drive rod 63 drives the transmission unit 7 to run.

[0065] Specifically, the transmission part 7 includes a circular mounting plate 71, which is arranged vertically. A connecting shaft 72 that can rotate on the inner wall of the mixing tank 4 is fixed at the center of one of the circular surfaces of the mounting plate 71. The connecting shaft 72 is mounted on the side wall of the mixing tank 4 through a connecting column 73. Specifically, multiple transmission rods 74 arranged in a ring array are fixed on the annular surface of the mounting plate 71. The transmission rods 74 are arranged vertically, and the transmission rods 74 arranged in a ring array mesh with the drive rods 63 arranged in a ring array to form a transmission connection structure. That is, when the drive rod 63 rotates with the drive stirring rod 5, a transmission rod 74 is arranged between the two drive rods 63 in the meshing area. One end of the connecting shaft 72 is provided with a feeding part 8; A stirring plate 75 is fixed on the transmission rod 74.

[0066] The moving drive rod 63 pushes the transmission rod 74 to move in a circular trajectory, thereby causing the transmission rod 74 to rotate. The transmission rod 74 drives the connecting plate connected to it to rotate, thereby driving the feeding part 8 to run.

[0067] During its movement, the transmission rod 74 assists in stirring vertically through the stirring blades 75 on its surface.

[0068] When the connecting disc rotates, it drives the connecting shaft 72 to rotate on the inner wall of the mixing tank 4.

[0069] The feeding part 8 operates by rotating the connecting shaft 72, which drives the discharging box 9 to reciprocate vertically within the mixing tank 4. The feeding section 8 is installed on the side wall of the mixing tank 4.

[0070] In this embodiment, the feeding unit 8 drives the dispensing box 9 to move back and forth in the vertical direction, so that the dispensing box 9 containing solid raw materials can enter the liquid surface of the ink mixture multiple times and stably, thereby ensuring that the solid raw materials are fully immersed in the liquid raw materials and avoiding problems such as the raw materials floating on the liquid surface and low dispersion efficiency in the traditional static feeding method.

[0071] Furthermore, the discharge box 9 is provided with a material leakage through hole. When the discharge box 9 enters below the liquid surface, the solid raw material can be automatically released into the liquid raw material through the through hole, realizing a precise and controllable material contact process, which is conducive to the uniform fusion of solid and liquid raw materials.

[0072] Furthermore, driven by the feeding section 8, the discharge box 9 is in a continuous motion state. Its vertical movement in the liquid not only enhances the disturbance contact between the raw material and the liquid, but also generates a stirring effect to a certain extent, which accelerates the wetting, dispersion and dissolution speed of the solid raw material, thereby significantly improving the efficiency and uniformity of the entire mixing process.

[0073] Furthermore, the feeding section 8 includes a lower pulley 81, which is sleeved and fixed on the connecting shaft 72. The lower pulley 81 is connected to the self-rotating upper pulley 82 via a conveyor belt 83. The upper pulley 82 is installed on the top of the side wall of the mixing barrel via a fixing member 84. At least one material box 9 is fixed on the conveyor belt 83; The upper pulley 82 is located on top of the lower pulley 81.

[0074] The fastener 84 has a "C" shaped structure and is fixed to the outer side wall of the mixing tank 4.

[0075] The rotation of the connecting shaft 72 drives the lower pulley 81 on its surface to rotate. The lower pulley 81 drives the upper pulley 82 to rotate through the conveyor belt 83. The feeding box 9 located on the conveyor belt 83 moves with the conveyor belt 83, thereby realizing the movement of the feeding box 9.

[0076] Furthermore, the surface of the feeding box 9 is provided with a plurality of material leakage through holes, and the outer wall of the feeding box 9 away from the feeding part 8 is provided with a material discharge channel for placing solid raw materials, that is, the side away from the conveyor belt 83. Preferably, the two ends of the feeding box 9 extend outward to form a symmetrical streamlined structure, and the area of ​​the feeding channel is less than half the area of ​​the side wall of the feeding box 9.

[0077] Solid raw materials are fed into the discharge box 9 through the discharge channel.

[0078] Example 4: Figure 5 and Figure 6 As shown, the surface of the material discharge channel is covered with a cover plate 91, the cover plate 91 is slidably connected to the outer wall of the material discharge box 9, and a spring-loaded unit is provided at the sliding connection between the material discharge box 9 and the cover plate 91. A triggering unit is provided on the top side of the feeding section 8, and the triggering unit pushes the cover plate 91 to slide. The triggering unit includes a force transmission unit disposed on the cover plate 91, and the force transmission unit and the limiting unit overlap, which move synchronously with the feeding box 9.

[0079] By covering the discharge channel with the cover plate 91, the solid raw materials are prevented from directly detaching from the discharge box 9 from the large discharge channel during the movement process, which would affect the feeding effect of the feeding section 8.

[0080] The spring-loaded unit includes a telescopic rod that is consistent with the sliding trajectory shape of the cover plate 91. The two ends of the telescopic rod are fixed to the cover plate 91 and the guide rail 92, respectively. A spring is sleeved on the surface of the telescopic rod, and the two ends of the spring are fixed to the two ends of the telescopic rod, respectively.

[0081] That is, by means of a telescopic rod with a spring, the cover plate 91 covers the discharge channel. When it is necessary to feed material, push the cover plate 91 to remove it from the discharge channel and pour solid raw materials into the discharge channel.

[0082] Release the cover plate 91, and under the elastic force of the spring, the cover plate 91 returns to its original position. The two sides of the material discharge channel are fixed with arc-shaped guide rails 92, and the arc-shaped cover plate 91 is slidably connected to the guide rails 92.

[0083] The force transmission unit is located on the eccentric side of the surface of the cover plate 91. The force transmission unit includes two symmetrically arranged connecting rods 93. The connecting rods 93 are fixed on the cover plate 91. A connecting collar 94 is fixed to the top of the connecting rods 93. The two connecting collars 94 are respectively sleeved on both ends of the rotating horizontal axis 95. The rotating horizontal axis 95 rotates inside the connecting collars 94. A driven push plate 96 is fixed to the surface of the horizontal axis 95 between the two connecting collars 94; The limiting unit includes a drive plate 98 that can be connected to the driven push plate 96. The drive plate 98 is fixedly connected to the mounting plate 99 via a fixing rod 97. The mounting plate 99 is fixed to the surface of the mounting shell 31 on the drive assembly 3. The drive plate 98 is disposed on one side of the top of the upper pulley 82; A torsion spring is provided at the connection between the connecting collar 94 and the rotating horizontal shaft 95, with both ends of the torsion spring fixed to the connecting collar 94 and the rotating horizontal shaft 95 respectively.

[0084] As the feeding box 9 moves with the conveyor belt 83, the eccentrically positioned force transmission unit first contacts the drive plate 98, that is, the driven push plate 96 on the force transmission unit first contacts the drive plate 98. The moving driven push plate 96 is pushed by the fixed drive plate 98, thereby causing the cover plate 91 to slide, so that the cover plate 91 is separated from the feeding channel, and solid raw materials are fed into the feeding box 9 through the open feeding channel. When feeding, the stirring speed can be appropriately slowed down.

[0085] During the above process, the torsion spring does not deform.

[0086] As the discharge box 9 continues to move, the driven push plate 96 drives the cover plate 91 to slide to its limit position. After the cover plate 91 stops moving, the torsion spring is pushed and deformed, and the driven push plate 96 starts to rotate. Thus, during the continuous movement, the driven push plate 96 disengages from the drive plate 98. After disengagement, the cover plate 91 returns to its original position under the action of the spring, and the driven push plate 96 also returns to its original position under the action of the torsion spring.

[0087] The extreme position of the sliding of the cover plate 91 can be achieved by a limiting structure. One embodiment is achieved by a connecting rope of a certain length, with one end of the connecting rope fixed to the cover plate 91 and the other end fixed to the guide rail 92. Another embodiment is to limit the extension or retraction of the telescopic rod.

[0088] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
