Description

Technical Field

[0001] The invention relates to the technical field of forced feeding conveyors, in particular to a light material forced feeding conveyor. Background Art

[0002] Forced feeding conveyor is a general optional conveying equipment, such as crusher and special belt conveyor combined into a complete system, used for secondary crushing and conveying of raw materials such as square bales, bulk straw and small pieces of materials.

[0003] For the transportation of the above-mentioned light materials, due to the integrated crushing process, when the blade is crushed, a large crushing depth is likely to cause damage to the belt, while insufficient crushing depth is likely to cause incomplete local crushing, affecting the quality of secondary crushing. Especially in the process of conveying bulk materials, due to the uneven density of light materials falling on the belt at the hopper outlet, when the light materials are loose, the instantaneous cutting amount is reduced, which affects the collection uniformity at the end and the feeding accuracy.

[0004] In addition, since debris is easily generated during the cutting and crushing process, it is easy to disperse in the air during subsequent processing or end collection, affecting the safety of operators. Summary of the invention

[0005] The object of the present invention is to provide a light material forced feeding conveyor to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solution: a light material forced feeding conveyor.

[0007] A forced feeding conveyor for light materials comprises a supporting device, a conveying device, a crushing device and an adjusting device. The supporting device is connected to the conveying device, the crushing device is connected to the supporting device, the adjusting device is connected to the supporting device, and the adjusting device is electrically connected to the conveying device. The supporting device comprises a head, a shell and a tail. The head, the shell and the tail are arranged in sequence along the feeding direction. A dust cover is provided on the shell. The adjusting device is used to adjust the feeding speed.

[0008] The supporting device is used to install and position other devices, and the conveying device is used to convey materials. During the conveying process, the light material is crushed by the crushing device, and after the crushing is completed, it is conveyed to the end for collection. The adjusting device is set to adjust the conveying of the light material. By adjusting the conveying speed of the light material, it is convenient to carry out full-load cutting and improve the cutting efficiency. The supporting device is set in three stages. The head is used to connect the feed, and the shell is used to convey the crushed material and convey it to the tail of the machine for collection. A dust cover is provided on the shell to prevent the broken debris from splashing and causing air pollution.

[0009] Furthermore, the conveying device includes a belt, a support plate, a head wheel, a driving motor and a tensioning assembly. The driving motor is tightly connected to the machine head, and the output end of the driving motor is transmission-connected to the head wheel. A crushing chamber is provided on the machine head, and the head wheel is placed in the crushing chamber. The head wheel and the machine head are rotationally connected. A tail material chamber is provided on the tail of the machine. The tensioning assembly includes a tail wheel, and the tail wheel is placed in the tail material chamber. The belt is connected end to end along the outer edges of the head wheel and the tail wheel. A conveying chamber is provided on the shell, and the crushing chamber, the conveying chamber and the tail material chamber are connected in sequence. The support plate is tightly connected to the walls of the crushing chamber, the conveying chamber and the tail material chamber, respectively, and the support plate is located on the inner ring of the belt, and the support plate is in contact with the inner ring of the belt.

[0010] The belt is the main conveying component. The support plate supports the belt and provides a support basis for the crushed materials. The belt is wrapped around the head wheel and the tail wheel. The drive motor is used to drive the head wheel to rotate, thereby driving the belt to move. The crushing chamber provides space for the crushing of light materials, the tailing chamber is used to discharge the crushed materials, and the conveying chamber is used to connect the crushing chamber and the tailing chamber for material transmission.

[0011] Furthermore, the tensioning assembly also includes a slide plate and an adjusting screw rod. Slide grooves are provided on both sides of the tail of the machine. The shaft ends on both sides of the tail wheel are inserted into the slide grooves. The slide plate and the slide grooves are slidably connected. The two ends of the tail wheel are respectively rotatably connected to the two slide plates. A threaded groove is provided on the slide plate. One end of the adjusting screw rod is rotatably connected to the tail of the machine, and the other end is threadedly connected to the threaded groove of the slide plate.

[0012] The adjusting screw is rotatably connected to the tail of the machine and is threadedly connected to the slide plate. The slide plates on both sides are used for double-end support of the UI tail wheel. When the adjusting screw is driven to rotate, the slide plate can be driven to move linearly along the slide groove. When the slide plate drives the tail wheel to move, the distance between the tail wheel and the head wheel is adjusted, which can be used to adjust the tension of the belt.

[0013] Furthermore, the crushing device includes a knife roller motor and a crushing knife roller. The knife roller motor is tightly connected to the machine head. The output end of the knife roller motor is transmission-connected to the crushing knife roller. Both ends of the crushing knife roller are rotationally connected to the machine head respectively. A plurality of blades are arranged on the crushing knife roller. The crushing knife roller crushes the light material by the blades.

[0014] When light materials enter the crushing station through the belt, the cutter roller motor outputs torque, which can be driven by belt drive or chain drive to drive the crushing cutter roller to rotate. During the rotation of the crushing cutter roller, several axially arranged blades automatically cut and crush the light materials. After the crushing is completed, the materials are output to the crushing station through the belt.

[0015] Furthermore, a dust removal air suction port is provided on the machine head, the dust removal air suction port is connected to the crushing chamber, and the upper end of the dust removal air suction port is connected to the negative pressure air source.

[0016] By setting up a dust removal suction port connected to a negative pressure air source, small particles of impurities generated during the crushing process can be automatically collected to prevent them from dispersing in the air and affecting the safety of operators.

[0017] Furthermore, the adjusting device includes a discharging assembly and a CCD camera, which is tightly connected to the upper wall of the crushing chamber. The discharging assembly, the crushing knife roller and the dust suction port are arranged in sequence along the feeding direction. The discharging assembly includes an auxiliary roller, a tensioning roller, a mounting seat and a contraction cylinder. A contraction groove is provided on the machine head, the contraction cylinder and the contraction groove are tightly connected, the output end of the contraction cylinder and the mounting seat are tightly connected, the tensioning roller and the crushing chamber are tightly connected, and both ends of the tensioning roller are rotatably connected to the mounting seat respectively. The support plate is arranged in a stepped shape, and the belt is bent in an "S" shape at the transition of the support plate step. The end of the support plate is a low end. The tensioning assembly also includes a tightening motor, which is tightly connected to the tail of the machine, and the output end of the tightening motor is tightly connected to the adjusting screw. The CCD camera is used to control the contraction cylinder and the tightening motor.

[0018] By setting up a CCD camera to perform visual inspection on the light materials fed, the feeding density is detected. When the feeding density reaches the standard value, the belt feeds the light materials into the crushing station for crushing. The support plate is set in a stepped shape, and the belt is fitted to the support plate through the tensioning roller and the auxiliary roller. When the feeding density is low, the CCD camera generates a corresponding electrical signal and transmits it to the controller. The controller drives the output end of the contraction cylinder to contract, driving the mounting seat to move toward the high end. At the same time, the output torque of the tightening motor drives the adjustment screw to rotate, and the slide plate and the tail wheel are driven to move in the same direction through the threaded engagement. The part between the belt at the low end and the belt at the high end is elongated, and the belt at the low end is decelerated, while the belt at the high end maintains a constant speed, so that the subsequent light materials move forward along the belt, and the low-density light materials are compressed and compensated, thereby improving the uniformity of feeding.

[0019] Furthermore, an adjustment slot is provided on the support plate, which is located at the transition point of the support plate step. The adjustment device also includes an air supply pipe, which is located at the adjustment slot. The air supply pipe inlet is connected to the positive pressure air source, and the air supply pipe outlet is directed toward the crushing roller crushing position.

[0020] The auxiliary roller and the tensioning roller pass through the adjustment slots respectively to prevent movement interference during density compensation. At the same time, the air supply pipe is installed through the adjustment slot, and air is blown in the direction of the crushing roller crushing material through the air supply pipe, thereby forming a pressure difference with the dust removal suction port above. This pressure difference drives the smaller light materials in the crushing process to flow in a directional manner, which is convenient for collection and reduces the smaller particles in the crushed materials after the crushing is completed.

[0021] Furthermore, the supporting device also includes a material guide plate, which is firmly connected to the shell, and is arranged along the two side ends and the bottom end of the belt, and a material chip gap is provided between the inner side wall of the material guide plate and the belt.

[0022] The crushing gap is smaller than the standard unit for cutting light materials. After the cut light materials are transported to the tail material chamber, they need to be collected through the crushing gap. Light materials smaller than the standard unit fall into the crushing gap and move with the belt circulation. When they re-enter the feeding station, the small-sized light materials are laid on the belt through friction to form a bottom layer. When loading, new light materials fall on the bottom layer, and the blades of the crushing knife roller can cut into the bottom layer, thereby fully cutting the light materials and improving the cutting quality. Since the bottom layer does not need to be cut, the blade does not need to penetrate the bottom layer, thereby preventing damage to the belt and ensuring the service life of the belt.

[0023] As an optimization, the forced feeding conveyor also includes side plates, which are connected to the walls of the crushing chamber, the conveying chamber and the tailing chamber in sequence. The side plates are provided to guide the conveying of light material raw materials and prevent the raw materials from falling into the lower part of the belt.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the support plate of the present invention adopts a stepped setting, and the belt is fitted to the support plate through the tensioning roller and the auxiliary roller. When the feeding density is low, the CCD camera generates a corresponding electrical signal and transmits it to the controller. The controller drives the output end of the contraction cylinder to contract, driving the mounting seat to move toward the high end. At the same time, the torque output by the tightening motor drives the adjustment screw to rotate, and the slide plate and the tail wheel are driven to move in the same direction through the threaded engagement. The part between the belt at the low end and the belt at the high end is elongated, and the belt at the low end is decelerated, while the belt at the high end maintains a constant speed, so that the subsequent light material moves forward along the belt, and the low-density light material is compressed and compensated, thereby improving the uniformity of feeding; the direction of crushing the material to the crushing knife roller is reached through the air supply pipe. Air is blown, thereby forming a pressure difference with the dust removal suction port above. This pressure difference drives the directional flow of smaller light materials in the crushing process, which is convenient for collection and reduces the smaller particles in the crushed materials after crushing. When the cut light materials are transported to the tailing chamber, they need to be collected through the crushing gap. Light materials smaller than the standard unit fall into the crushing gap and move with the belt circulation. When re-entering the feeding station, small-sized light materials are laid on the belt through friction to form a bottom layer. When loading, new light materials fall on the bottom layer, and the blade of the crushing knife roller can cut into the bottom layer, thereby fully cutting the light materials and improving the cutting quality. Since the bottom layer does not need to be cut, the blade does not need to penetrate the bottom layer, thereby preventing damage to the belt and ensuring the service life of the belt.

A tail material chamber 131 is provided on the tail 13. The tensioning assembly 25 includes a tail wheel 251, and the tail wheel 251 is placed in the tail material chamber 131. The belt 21 is connected end to end along the outer edges of the head wheel 23 and the tail wheel 251. A conveying chamber 121 is provided on the shell 12. The crushing chamber 111, the conveying chamber 121 and the tail material chamber 131 are connected in sequence. The supporting plate 22 is tightly connected to the walls of the crushing chamber 111, the conveying chamber 121 and the tail material chamber 131 respectively. The supporting plate 22 is located at the inner circle of the belt 21, and the supporting plate 22 contacts the inner circle of the belt 21.

[0038] The belt 21 is used as the main conveying component. The belt 21 is supported by the support plate 22 to provide a support basis for the crushed materials. The belt 21 is wrapped around the head wheel 23 and the tail wheel 251. The driving motor 24 is used to drive the head wheel 23 to rotate, thereby driving the belt 21 to move. The crushing chamber 111 provides space for crushing light materials, the tailing chamber 131 is used to discharge the crushed materials, and the conveying chamber 121 is used to connect the crushing chamber 111 and the tailing chamber 131 for material transmission.

[0039] like Figure 2~Figure 3 As shown, the tensioning assembly 25 also includes a slide plate 252 and an adjusting screw rod 253. Slide grooves 132 are provided on both sides of the tail 13. The shaft ends on both sides of the tail wheel 251 are inserted into the slide grooves 132. The slide plate 252 is slidably connected to the slide grooves 132.

[0040] The adjusting screw rod 253 is rotatably connected to the tail 13 and is threadedly connected to the slide plate 252. The slide plates 252 on both sides are used to support the UI tail wheel 251 at both ends. When the adjusting screw rod 253 is driven to rotate, the slide plate 252 can be driven to move linearly along the slide groove 132. When the slide plate 252 drives the tail wheel 251 to move, the distance between the tail wheel 251 and the head wheel 23 is adjusted, which can be used to adjust the tension of the belt 21.

[0041] like Figure 1~Figure 2 As shown, the crushing device 3 includes a knife roller motor 31 and a crushing knife roller 32. The knife roller motor 31 is firmly connected to the machine head 11. The output end of the knife roller motor 31 is transmission-connected to the crushing knife roller 32. Both ends of the crushing knife roller 32 are rotationally connected to the machine head 11 respectively. A plurality of blades are provided on the crushing knife roller 32. The crushing knife roller 32 crushes light materials through the blades.

[0042] When light materials enter the crushing station through the belt 21, the knife roller motor 31 outputs torque, which can be in the form of belt drive or chain drive to drive the crushing knife roller 32 to rotate. During the rotation of the crushing knife roller 32, several axially arranged blades automatically cut and crush the light materials. After the crushing is completed, the crushing station is output through the belt 21.

[0043] like Figure 2~Figure 3 As shown, a dust removal air suction port 112 is provided on the machine head 11, the dust removal air suction port 112 is connected to the crushing chamber 111, and the upper end of the dust removal air suction port 112 is connected to a negative pressure air source.

[0044] A dust removal suction port 112 connected to a negative pressure air source is provided to automatically collect small particle impurities generated during the crushing process to prevent them from being dispersed in the air and affecting the safety of operators.

[0045] like Figure 1~Figure 5 As shown, the adjusting device 4 includes a discharge assembly 41 and a CCD camera 42, the CCD camera 42 is fastened to the upper wall of the crushing chamber 111, the discharge assembly 41, the crushing knife roller 32 and the dust suction port 112 are arranged in sequence along the feeding direction, the discharge assembly 41 includes an auxiliary roller 411, a tensioning roller 412, a mounting seat 413 and a contraction cylinder 414, a contraction groove 113 is provided on the head 11, the contraction cylinder 414 is fastened to the contraction groove 113, and the output end of the contraction cylinder 414 is fastened to the mounting seat 413 Then, the tensioning roller 412 is tightly connected to the crushing chamber 111, and both ends of the tensioning roller 412 are rotatably connected to the mounting seat 413 respectively. The support plate 22 is arranged in a stepped shape, and the belt 21 is bent in an "S" shape at the step transition of the support plate 22. The end of the support plate 22 is a low end. The tensioning assembly 25 also includes a tightening motor 254, and the tightening motor 254 is tightly connected to the tail 13. The output end of the tightening motor 254 is tightly connected to the adjusting screw rod 253, and the CCD camera 42 is used to control the contraction cylinder 414 and the tightening motor 254.

[0046] The CCD camera 42 is set to perform visual inspection on the light material fed, so as to detect the feeding density. When the feeding density reaches the standard value, the belt 21 feeds the light material into the crushing station for crushing. The support plate 22 is set in a stepped shape. The belt 21 is fitted to the support plate 22 through the tensioning roller 412 and the auxiliary roller 411. When the feeding density is low, the CCD camera 42 generates a corresponding electrical signal and transmits it to the controller. The controller drives the output end of the contraction cylinder 414 to contract, driving the mounting seat 413 to move toward the high end. At the same time, the torque is output by the tightening motor 254 to drive the adjusting screw rod 253 to rotate, and the slide plate 252 and the tail wheel 251 are driven to move in the same direction through the threaded engagement. The part between the belt 21 at the low end and the belt 21 at the high end is stretched, and the belt 21 at the low end is decelerated, while the belt 21 at the high end maintains a constant speed, so that the subsequent light material moves forward along the belt 21, and the low-density light material is compressed and compensated, thereby improving the uniformity of feeding.

[0047] like Figure 5~Figure 6 As shown, an adjustment groove 221 is provided on the support plate 22, and the adjustment groove 221 is located at the step transition of the support plate 22. The adjustment device 4 also includes an air supply pipe 43, and the air supply pipe 43 is located at the adjustment groove 221. The inlet of the air supply pipe 43 is connected to the positive pressure air source, and the outlet of the air supply pipe 43 is toward the crushing position of the crushing knife roller 32.

[0048] The auxiliary roller 411 and the tensioning roller 412 pass through the adjustment slot 221 respectively to prevent movement interference during density compensation. At the same time, the air supply pipe 43 is installed through the adjustment slot 221, and air is blown in the direction of the crushing knife roller 32 through the air supply pipe 43, thereby forming a pressure difference with the dust removal suction port 112 above. This pressure difference drives the smaller light materials in the crushing process to flow in a directional manner, which is convenient for collection and reduces the smaller particles in the crushed materials after the crushing is completed.

[0049] like Figure 1~Figure 3 As shown, the support device 1 further comprises a guide plate 14 , which is firmly connected to the housing 12 , and is arranged along the two side ends and the bottom end of the belt 21 , with a material chip gap provided between the inner side wall of the guide plate 14 and the belt 21 .

[0050] The crushing gap is smaller than the standard unit for cutting light materials. After the cut light materials are transported to the tail material chamber 131, they need to be collected through the crushing gap. Light materials smaller than the standard unit fall into the crushing gap and move in a cycle with the belt 21. When re-entering the feeding station, small-sized light materials are driven by friction to be laid on the belt 21 to form a bottom layer. When loading, new light materials fall on the bottom layer, and the blades of the crushing knife roller 32 can cut into the bottom layer, thereby fully cutting the light materials and improving the cutting quality. Since the bottom layer does not need to be cut, the blade does not need to penetrate the bottom layer, thereby preventing damage to the belt 21 and ensuring the service life of the belt 21.

[0051] As an optimization, the forced feeding conveyor further includes a side plate 6, which is sequentially connected to the walls of the crushing chamber 111, the conveying chamber 121 and the tailing chamber 131. The side plate is provided to guide the light material to be conveyed and prevent the material from falling into the lower part of the belt 21.

[0052] The working principle of the present invention is as follows: the support plate 22 is arranged in a stepped shape, and the belt 21 is made to fit the support plate 22 through the tensioning roller 412 and the auxiliary roller 411. When the feeding density is low, the CCD camera 42 generates a corresponding electrical signal and transmits it to the controller. The controller drives the output end of the contraction cylinder 414 to contract, driving the mounting seat 413 to move toward the high end. At the same time, the torque is output by the tightening motor 254 to drive the adjusting screw rod 253 to rotate, and the slide plate 252 and the tail wheel 251 are driven to move in the same direction through the threaded engagement. The part between the belt 21 at the low end and the belt 21 at the high end is stretched, and the belt 21 at the low end is decelerated, while the belt 21 at the high end maintains a constant speed, so that the subsequent light material moves forward along the belt 21, and the low-density light material is compressed and compensated, thereby improving the uniformity of feeding; the air supply pipe 43 is used to supply air to the crushing knife The roller 32 blows air in the direction of the crushed material, thereby forming a pressure difference with the dust suction port 112 above. This pressure difference drives the directional flow of smaller light materials in the crushing process, which is convenient for collection and reduces the smaller particles in the crushed material after the crushing is completed; when the cut light materials are transported to the tail material chamber 131, they need to be collected through the crushing gap. Light materials smaller than the standard unit fall into the crushing gap and move in a cycle with the belt 21. When re-entering the feeding station, the small-sized light materials are laid on the belt 21 through friction to form a bottom layer, so that when loading, new light materials fall on the bottom layer, and the blade of the crushing knife roller 32 can cut into the bottom layer, thereby fully cutting the light materials and improving the cutting quality. Since the bottom layer does not need to be cut, the blade does not need to penetrate the bottom layer, thereby preventing damage to the belt 21 and ensuring the service life of the belt 21.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
