The left and right ends of the mounting plate are rotatably connected to sprockets through a rotating shaft, and the two sprockets are connected by a chain transmission. A motor is provided on the upper surface of the mounting plate, and the output shaft of the motor is fixedly connected to the rotating shaft on the left, and the input end of the motor is electrically connected to the output end of the external control switch; the auxiliary support assembly: fixedly connected to the front and rear sides of the mounting plate respectively, the auxiliary support assembly is fixedly connected to the chain, and the auxiliary support assembly includes an L-shaped frame, rollers, an L-shaped plate and a track. The suspension assembly: an array is arranged on the lower surface of the chain. The bean curd skin hanging and conveying device can quickly suspend and remove the bean curd skin, is simple and convenient to operate, and improves work efficiency.

[0004] This patented technology has the advantage of easy operation when used, but there are still shortcomings during use. The suspended conveying device has a single function. When the production process or product characteristics change, such as the need to handle the transportation of a large amount of bulk materials or powdered materials, the original suspended conveying device cannot meet the new transportation needs. Therefore, those skilled in the art provide a suspended conveying device to solve the problems raised in the above background technology. Summary of the Invention

[0005] The purpose of the present invention is to provide a suspension conveying device in response to the problems existing in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a suspension conveying device, comprising a mounting frame, a suspension conveying structure, a belt conveying structure and an adjustment structure, characterized in that:

[0007] The suspension conveying structure includes a top frame fixed on the upper end of the mounting frame, a motor 1 located at the upper end of the top frame, a rotating shaft rotatably installed inside the top frame and symmetrically distributed, a gearbox connected to the output end of the motor 1 and the output end connected to the rotating shaft, a sprocket sleeved on the outer wall of the rotating shaft, a chain sleeved on the outer wall of the sprocket, and a hook located below the chain;

[0008] The belt conveyor structure includes a suspension fixedly placed below the top frame and rotatably mounted to the lower end of the rotating shaft, a lifting plate located below the suspension, two conveying rollers rotatably mounted inside the upper end of the lifting plate and evenly spaced, first conveying rollers located at the lower end of the rotating shaft and evenly spaced and rotatably mounted to the lower end of the suspension, and a lifting plate located inside the lower end of the mounting frame and rotatably mounted to the second conveying roller.

[0009] The regulating structure comprises a second motor fixed on the upper end of the bottom plate, and a screw located at the output end of the second motor and with outer wall threads relatively distributed.

[0010] Preferably, the lower end of the mounting frame is provided with a support surface 1, which keeps the suspended conveying structure upright when the mounting frame is supported by the support surface 1. The support surface 1 ensures that the suspended conveying structure is vertically stressed to prevent the chain from getting stuck or falling off due to tilting.

[0011] Preferably, the rear end of the mounting frame is provided with a second support surface, and the belt conveyor structure remains horizontal when the mounting frame is supported by the second support surface. The second support surface supports the mounting frame, and when it is in contact with the ground, the conveyor belt is adjusted from vertical to horizontal.

[0012] Preferably, a positioning sleeve is fixed below the conveyor mounting frame and is sleeved on the outside of the chain. Ball bearings are rotatably mounted on the inner walls of the front and rear ends of the positioning sleeve, which fit against the outer wall of the chain. The balls roll in contact with the chain, reducing lateral chain movement and preventing material from falling off due to hook swinging.

[0013] Preferably, the lower end of the chain is equipped with equally spaced threaded rods, with threaded sleeves threadedly mounted on the outer walls of the rods. The lower end of the threaded sleeves is provided with a mounting frame fixedly connected to the hook. The threaded sleeve design allows for fine-tuning of the hook height (e.g., to accommodate materials with different lifting spacings) and facilitates replacement of damaged hooks.

[0014] Preferably, the outer walls of the first and second conveyor rollers are sleeved with limit rings, and the interior of the first conveyor roller is provided with an interlocking groove. One end of the second conveyor roller is provided with an interlocking clip that slides into the inner wall of the interlocking groove. This interlocking structure ensures that the first and second conveyor rollers rotate synchronously, preventing belt deviation due to roller speed differences, and also allows the overall length of the first and second conveyor rollers to be adjusted.

[0015] Preferably, the lifting plate and the outer wall of the mounting frame are both provided with symmetrically distributed guide rails, and the outer walls of the guide rails are slidably mounted with multiple sets of symmetrically distributed sliders, one end of which is provided with a rotating seat. The guide rails define the lifting path, prevent the lifting plate from tilting or shaking, and ensure the stable transportation of precision materials.

[0016] Preferably, two groups of shear plates 1 and 2, which are symmetrically distributed and cross each other, are provided under the lifting plate, and one end of the shear plate 1 and the shear plate 2 is provided with a mounting shaft rotatably mounted inside the mounting seat, and the center of the shear plate 1 and the shear plate 2 is rotatably mounted, and a nut is threadedly mounted on the outer wall of the screw, and a fixing seat fixedly connected to the central shaft is provided on the upper end of the nut, and a mounting groove is opened inside the mounting frame, and a spring is provided on the inner wall of the upper end of the mounting groove, and a travel rod is provided at the lower end of the spring, and a handle is provided at the front end of the travel rod, and a connecting rod is provided at one end of the travel rod, and a positioning cylinder and a positioning rod slidably inserted and located inside the spring are provided on the upper end of the travel rod, and the upper end of the positioning rod is connected to the inner wall of the upper end of the mounting groove.

[0017] Preferably, a tooth plate 1 is provided at one end of the slider, a hydraulic rod is provided at the front end of the lifting plate, and a tooth plate 2 is provided at the output end of the hydraulic rod to engage with tooth plate 1. When the hydraulic rod drives tooth plate 2 to move toward tooth plate 1, tooth plate 1 is fixed to prevent the slider from sliding freely after adjustment.

[0018] Preferably, the steps for using the hanging conveyor are as follows:

[0019] S1: When the hanging conveying structure is used, the motor drives the rotating shaft to rotate through the gearbox, and then drives the sprocket to rotate. When the sprocket rotates, it drives the chain to rotate, and drives the hook to move along with the chain. When the hook moves, the workpiece or item is hooked on the hook. During the hooking process, it is necessary to grasp the handle to apply an upward squeezing force to the spring. Through the elastic support of the spring, the goods or workpieces hooked on the outer wall of the hook are pressed and held, so that the stability of the goods is improved when moving;

[0020] S2: When the belt conveyor structure is in use, the supporting surface 2 is in contact with the ground, and the conveyor belt remains horizontal. When the rotating shaft rotates, the conveyor roller 1 is also driven to rotate. Because the conveyor roller 1 is slidably plugged into the conveyor roller 2, under the action of the rotating force, the conveyor roller 2 is driven to rotate through the sliding engagement relationship between the engaging strip and the engaging groove. The conveyor roller 1 and the conveyor roller 2 are driven to rotate by the friction of the conveyor belt, thereby realizing the transportation of bulk materials or powdered materials.

[0021] S3: When the conveyor belt is transporting large objects, motor 2 drives the screw to rotate, and the lateral force acts on the center rod through the relatively distributed threads on the outer wall of the screw. The center rod pulls shear plate 1 and shear plate 2 to move relative to or away from each other. At the same time, through the sliding installation of the slider and the guide rail, and the rotating installation of the rotating seat and the mounting shaft, shear plate 1 and shear plate 2 apply supporting force to the lifting plate. During the movement of the lifting plate, the conveyor roller 1 is driven to move, and then the width of the conveyor roller is adjusted. Conveyor belts of different specifications can be assembled to meet the transportation of items and materials of different specifications.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When the suspended conveying structure of the present invention is placed upright, the longitudinally installed hook conveys articles or workpieces. When the mounting frame is laid down, the upright conveyor belt is horizontal, thereby realizing the conveying of a large amount of bulk materials and powdered materials. The hook is threadedly installed on the threaded rod through a threaded sleeve, and the threaded rod is connected to the chain and can be disassembled after hanging, thereby avoiding obstruction to the conveying structure when the belt conveying structure needs to be used. When the production process or product characteristics change, the suspended conveying device can be used flexibly. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0043] See also Figures 1 to 13 , the present invention provides four embodiments:

[0044] Example 1:

[0045] A suspension conveying device includes a mounting frame 100, a suspension conveying structure 200, a belt conveying structure 300 and an adjustment structure 400.

[0046] The hanging conveying structure 200 includes a top frame 201 fixed to the upper end of the mounting frame 100, a motor 202 located at the upper end of the top frame 201, rotating shafts 205 symmetrically distributed and rotatably mounted inside the top frame 201, a gearbox 203 connected to the output end of the motor 202 and the output end connected to the rotating shaft 205, a sprocket 206 sleeved on the outer wall of the rotating shaft 205, a chain 208 sleeved on the outer wall of the sprocket 206, and a hook 214 located below the chain 208;

[0047] The lower end of the mounting frame 100 is provided with a support surface 101, and the support surface 101 supports the mounting frame 100 to keep the suspension conveying structure 200 upright;

[0048] The rear end of the mounting frame 100 is provided with a second support surface 102, and the second support surface 102 keeps the belt conveyor structure 300 horizontal when supporting the mounting frame 100;

[0049] A positioning sleeve 204 is fixed below the conveyor mounting frame 100 and is sleeved on the outside of the chain 208. Balls 207 are rotatably mounted on the inner walls of both ends of the positioning sleeve 204 and are attached to the outer wall of the chain 208.

[0050] The lower end of the chain 208 is provided with equidistantly distributed threaded rods 209, the outer wall of the threaded rod 209 is threadedly sleeved with a threaded sleeve 210, and the lower end of the threaded sleeve 210 is provided with a mounting frame 211 fixedly connected to the hook 214;

[0051] The mounting frame 211 has a mounting slot 219 formed inside. A spring 217 is provided on the inner wall of the upper end of the mounting slot 219. A travel rod 212 is provided on the lower end of the spring 217. A handle 215 is provided on the front end of the travel rod 212. A connecting rod 213 is provided on one end of the travel rod 212. A positioning cylinder 218 and a positioning rod 216 are provided on the upper end of the travel rod 212. The positioning cylinder 218 and the positioning rod 216 are slidably inserted and located inside the spring 217. The upper end of the positioning rod 216 is connected to the inner wall of the upper end of the mounting slot 219.

[0052] The motor 202 drives the symmetrically distributed shaft 205 to rotate through the gearbox 203, driving the sprocket 206 to rotate synchronously, driving the sprocket 206 to rotate synchronously, the sprocket 206 drives the chain 208 to move circularly, and the hook 214 under the chain 208 moves horizontally accordingly, realizing the hanging conveying of materials. The positioning sleeve 204 on the outside of the chain 208 rolls with the chain 208 through the internal ball 207, suppressing the lateral swing of the chain 208 and ensuring the stability of the path of the hook 214.

[0053] Example 2:

[0054] The belt conveyor structure 300 includes a suspension frame 301 fixed below the top frame 201 and rotatably mounted to the lower end of the rotating shaft 205; a lifting plate 304 located below the suspension frame 301; second conveyor rollers 305 rotatably mounted inside the upper end of the lifting plate 304 and evenly spaced; first conveyor rollers 302 located below the rotating shaft 205 and evenly spaced and rotatably mounted to the lower end of the suspension frame 301; and the lifting plate 304 located inside the lower end of the mounting frame 100 and rotatably mounted to the second conveyor rollers 305.

[0055] The outer walls of the conveyor roller 1 302 and the conveyor roller 2 305 are sleeved with a limit ring 306. The conveyor roller 1 302 has an interlocking groove 308 formed inside. One end of the conveyor roller 2 305 is provided with an interlocking clip 307 that is slidably inserted into the inner wall of the interlocking groove 308.

[0056] The mounting frame 100 is brought into horizontal contact with the ground through the supporting surface 2 102, so that the suspension 301 and the lifting plate 304 are adjusted and flipped, and the upright conveying roller 1 302 and the conveying roller 2 305 are horizontal. The rotating shaft 205 drives the conveying roller 1 302 to rotate, and the engaging groove 308 of the conveying roller 2 305 is engaged with the engaging strip 307 to achieve synchronous rotation, driving the conveyor belt 303 to transport materials. The existing suspended conveyor can only handle suspended materials and cannot meet the transportation needs of bulk materials or large-volume boxes. By integrating the belt conveyor structure 300, dual-mode switching between suspension and plane transportation is achieved to cover a variety of material types.

[0057] Example 3:

[0058] The adjustment structure 400 includes a second motor 401 fixed to the upper end of the bottom plate, and a screw 412 located at the output end of the second motor 401 and having outer wall threads arranged in opposite directions.

[0059] The outer walls of the lifting plate 304 and the mounting frame 100 are both provided with symmetrically distributed guide rails 404. The outer walls of the guide rails 404 are slidably mounted with multiple sets of symmetrically distributed sliders 415. One end of the slider 415 is provided with a rotating seat 405.

[0060] Two sets of symmetrically distributed and mutually intersecting shear plates 1 402 and 2 403 are provided below the lifting plate 304. One end of each of the shear plates 1 402 and 2 403 is provided with a mounting shaft 408 rotatably mounted inside a mounting seat. A central shaft 406 is rotatably mounted at the center of each of the shear plates 1 402 and 2 403. A nut 410 is threadedly sleeved on the outer wall of a screw rod 412. A fixing seat 411 is provided at the upper end of the nut 410 and fixedly connected to the central shaft 406.

[0061] A tooth plate 1 413 is provided at one end of the slider 415, a hydraulic rod 409 is provided at the front end of the lifting plate 304, and a tooth plate 2 414 is provided at the output end of the hydraulic rod 409 to engage with the tooth plate 1 413;

[0062] The second motor 401 drives the screw 412 to rotate, and the nut 410 drives the shear plate 1 402 and the shear plate 2 403 to move crosswise, changing the height of the lifting plate 304, thereby adjusting the distance between the conveyor roller 1 302 and the conveyor roller 2 305 to adapt to conveyor belts 303 of different widths. The hydraulic rod 409 pushes the tooth plate 2 414 to engage with the tooth plate 1 413, fixing the position of the slider 415 to ensure the stability of the structure after adjustment. The cross angle of the shear plate is driven by the screw 412 to accurately control the lifting height of the lifting plate 304 to meet the docking requirements of different workstations. The threaded sleeve 210 design allows the hook 214 to be quickly disassembled to avoid interfering with the operation of the belt conveyor mode. Traditional equipment cannot flexibly adjust the conveying height and width, and is difficult to adapt to different production line specifications. The shear plate and screw 412 cooperate to achieve tight-level lifting. The interlocking card strip 307 allows the conveyor roller to be extended and retracted to adapt to conveyor belts 303 of different widths, suitable for conveying bulk screws, rubber sealing strips, and conveying bulk materials such as flour and powdered sugar, thereby improving the flexibility of use.

[0063] Example 4:

[0064] The steps for using the hanging conveyor are as follows:

[0065] S1: When the hanging conveying structure 200 is in use, the motor 1 202 drives the rotating shaft 205 to rotate through the gearbox 203, thereby driving the sprocket 206 to rotate. When the sprocket 206 rotates, it drives the chain 208 to rotate, driving the hook 214 to move along with the chain 208. When the hook 214 moves, the workpiece or article is hooked on the hook 214. During the hooking process, it is necessary to grasp the handle 215 to apply an upward squeezing force to the spring 217. Through the elastic support of the spring 217, the goods or workpieces hooked on the outer wall of the hook 214 are pressed and held, thereby improving the stability of the goods when moving;

[0066] S2: When the belt conveyor structure 300 is in use, the second supporting surface 102 is in contact with the ground, and the conveyor belt 303 is kept horizontal. When the rotating shaft 205 rotates, the conveyor roller 1 302 is also driven to rotate. Because the conveyor roller 1 302 is slidably plugged into the conveyor roller 2 305, under the action of the rotational force, the conveyor roller 2 305 is driven to rotate through the sliding engagement relationship between the engaging strip 307 and the engaging groove 308. The conveyor roller 1 302 and the conveyor roller 2 305 drive the conveyor belt 303 to rotate through friction, thereby realizing the transportation of bulk materials or powdered materials.

[0067] S3: When the conveyor belt 303 is conveying large objects, the motor 2 401 drives the screw 412 to rotate, and the lateral force acts on the central shaft 406 through the relatively distributed threads on the outer wall of the screw 412. The central shaft 406 pulls the shear plate 1 402 and the shear plate 2 403 to move relative to or away from each other. At the same time, through the sliding installation of the slider 415 and the guide rail 404, and the rotating installation of the rotating seat 405 and the installation shaft 408, the shear plate 1 402 and the shear plate 2 403 apply a supporting force to the lifting plate 304. During the movement of the lifting plate 304, the conveyor roller 1 302 is driven to move, and then the width of the conveyor roller is adjusted. Conveyor belts 303 of different specifications can be assembled to meet the transportation of items and materials of different specifications.

[0068] The above specific embodiments are only several preferred embodiments of the present invention.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.

10. The hanging conveying device according to claim 1, characterized in that: The steps for using the hanging conveyor are as follows: S1: When the hanging conveying structure (200) is used, the motor 1 (202) operates to drive the rotating shaft (205) to rotate through the gearbox (203), thereby driving the sprocket (206) to rotate. When the sprocket (206) rotates, it drives the chain (208) to rotate, driving the hook (214) to move along with the chain (208). When the hook (214) moves, the workpiece or article is connected to the hook (214). During the connection process, it is necessary to grasp the handle (215) to apply an upward squeezing force to the spring (217). Through the elastic support of the spring (217), the goods or workpiece connected to the outer wall of the hook (214) are pressed and held, so that the stability of the goods is improved when the goods are moved; S2: When the belt conveyor structure (300) is in use, the second supporting surface (102) is in contact with the ground, and the conveyor belt (303) is kept horizontal. When the rotating shaft (205) rotates, the conveyor roller (302) is also driven to rotate. Since the conveyor roller (302) is slidably engaged with the conveyor roller (305), the conveyor roller (305) is driven to rotate by the sliding engagement relationship between the engagement strip (307) and the engagement groove (308) under the action of the rotational force. The conveyor roller (302) and the conveyor roller (305) are driven to rotate by the friction with the conveyor belt (303), thereby realizing the transportation of bulk materials or powdered materials. S3: When the conveyor belt (303) is conveying large objects, the motor 2 (401) drives the screw (412) to rotate. Through the threads relatively distributed on the outer wall of the screw (412), the lateral force acts on the central shaft (406). The central shaft (406) pulls the shear plate 1 (402) and the shear plate 2 (403) to move relative to or away from each other. At the same time, through the sliding installation of the slider (415) and the guide rail (404), and the rotation installation of the rotating seat (405) and the installation shaft (408), the shear plate 1 (402) and the shear plate 2 (403) apply a supporting force to the lifting plate (304). During the movement of the lifting plate (304), the conveying roller 1 (302) is driven to move, thereby adjusting the width of the conveying roller. Conveyor belts (303) of different specifications can be assembled to meet the transportation of items and materials of different specifications.
