Description

Technical Field

[0001] The present invention relates to conductive rubber strip packaging equipment, specifically an automatic box-packaging machine for conductive rubber strips. Background Art

[0002] Conductive rubber strips are commonly known as zebra rubber strips, which are vulcanized and formed after being alternately laminated with conductive silicone and insulating silicone.

[0003] The electrode spacing of conductive rubber strips can be made very small, so they are suitable for products with a large number of driving circuits, and are inexpensive; they are soft and elastic, and are convenient for alignment, and are mainly used for signal connection between LCDs and PCB boards, and have good electrical conductivity and stability.

[0004] During the production of conductive rubber strips, a slitting process is required. After being cut into thin strips by a cutter, and finally after quality inspection, the conductive rubber strips are in a disorderly state, and in this state, it is not conducive to the automatic packaging of products. At present, during the packaging process, conductive rubber strip manufacturers still use manual packaging. Usually, workers first align the conductive rubber strips neatly, and then bundle them in bundles of 500 or 1000. The quantity of each bundle is determined by weighing. Using manual packaging for conductive rubber strips has a large workload and low efficiency. At the same time, the product quality and the number of bags cannot be accurately controlled, and the packaging requirements of customers cannot be met. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic box-packaging machine for conductive rubber strips to solve the problems existing in the manual packaging of conductive rubber strips. This packaging machine can replace manual packaging and achieve automatic, efficient, and accurate box-packaging of conductive rubber strips to meet the packaging requirements of customers.

[0006] The technical solution to achieve the purpose of the present invention is as follows:

[0007] An automatic box-packaging machine for conductive rubber strips includes a frame arranged in a gradient from top to bottom. Different from the prior art, it further includes a feeding component, a combing component, and a packaging component arranged in a gradient from top to bottom on the frame;

[0008] The feeding component includes a current-limiting component, a dispersing component, and a blowing component arranged in sequence; the feeding component has the functions of limited feeding, intermittent feeding, and dispersed feeding, and at the same time, the feeding speed is required to be not less than 500 conductive rubber strips per minute;

[0009] The combing component includes a combing plate, a height-limiting component, a spring connection component, and an angle adjustment frame. The function of this component is to comb the conductive rubber strips from a scattered and disorderly state into an orderly state;

[0010] The packaging component includes a buffering component, a conveying component, and a collecting component. The function of this component is to achieve automatic box-packaging of a specified number of conductive rubber strips.

[0011] The current-limiting component of the feeding assembly includes a material chute, a first synchronous belt, and a servo motor;

[0012] The material chute is arranged above the first synchronous belt. Inside the material chute, current-limiting plates are arranged at a certain interval and perpendicular to the first synchronous belt. The distance between the bottom surface of the current-limiting plate and the first synchronous belt is adjusted by an adjustment slide rail installed on the inner side wall of the material chute, and the current-limiting plate is adapted to the adjustment slide rail;

[0013] The servo motor drives the movement of the first synchronous belt;

[0014] The current-limiting plates divide the material chute into multiple material chutes, and the lengths of the multiple material chutes are longer in the front and shorter in the back;

[0015] The conductive rubber strip is poured into the material chute and conveyed forward by the first synchronous belt. The distance between the current-limiting plate and the first synchronous belt restricts the flow rate of the conductive rubber strip conveyed forward. According to requirements, multiple current-limiting plates can be set to achieve the purpose of multi-stage current limiting, and the height of the current-limiting plate can also be adjusted according to actual production needs to adjust the feeding speed.

[0016] The dispersing component of the feeding assembly is installed at the rear end of the current-limiting component and above the first synchronous belt. The dispersing component includes a magnetic coupling rodless cylinder and a brush;

[0017] Both ends of the magnetic coupling rodless cylinder are connected to the cylinder mounting blocks and are fixed to the gantry of the machine frame in a suspended form through the cylinder mounting blocks. The magnetic coupling rodless cylinder is connected to the brush through a brush adjusting rod arranged on the brush, and the brush adjusting rod can adjust the height between the brush and the first synchronous belt according to actual production needs;

[0018] A limit switch is arranged on the magnetic coupling rodless cylinder, and the moving stroke of the magnetic coupling rodless cylinder and the brush is controlled by the limit switch. The limit switch is installed on the limit switch mounting plate;

[0019] The magnetic coupling rodless cylinder makes a reciprocating movement, and the movement is transmitted to the brush, driving the brush to make a reciprocating movement. When the conductive rubber strip that is agglomerated flows through, it is dispersed and separated by the brush and then conveyed forward.

[0020] The blowing component of the feeding assembly includes a mounting bracket, a receiving plate, and a blowing device;

[0021] The receiving plate is inclined at 35 - 45 degrees to the horizontal plane and is arranged against the end of the first synchronous belt. Baffles are arranged on the left and right sides of the receiving plate, and the baffles are fixedly connected to the packaging machine frame through connecting pieces;

[0022] The blowing device includes a first cylinder, a shunt row, a shunt row mounting plate, a high-pressure air nozzle, an air nozzle linkage rod, an adjusting plate, and a blowing device mounting plate;

[0023] The first cylinder is fixed on the frame. The mounting plate of the blowing device is installed at the end of the receiving plate. The shunt row is fixedly connected to its mounting plate. The mounting plate of the shunt row and the mounting plate of the blowing device are connected with a clearance through a connecting piece;

[0024] The high-pressure nozzles are arranged on the shunt row. The nozzle linkage rod is arranged in the clearance between the mounting plate of the shunt row and the mounting plate of the blowing device. The nozzle linkage rod is connected to the first cylinder;

[0025] An adjusting plate is installed on the back of the mounting plate of the blowing device. The adjusting plate and the mounting bracket of the blowing component are connected through a connecting shaft. The angle of the mounting plate of the blowing device is controlled by rotating the adjusting plate;

[0026] The mounting bracket of the blowing component is fixed on the frame of the packaging machine.

[0027] A U-shaped groove is provided on the mounting bracket of the blowing component. A connecting shaft is provided at the upper part of the U-shaped groove;

[0028] The adjusting plate is T-shaped. A through hole is provided on its vertical block and is adapted to the connecting shaft on the mounting bracket of the blowing component.

[0029] The conductive rubber strip drops from the first synchronous belt onto the inclined receiving plate. The conductive rubber strip slides down along the receiving plate due to inertia and gravitational potential energy. The high-pressure nozzles of the blowing device are responsible for using high pressure to blow the falling conductive rubber strip. To improve the success rate of blowing, a shunt row is used for high-pressure gas shunting, and multiple high-pressure nozzles are installed. At the same time, to make the conductive rubber strip more dispersed, power is provided by the first cylinder, and mechanisms such as the mounting plate of the blowing device, the high-pressure nozzle linkage rod, and the mounting plate of the shunt row are used to make the high-pressure nozzles swing left and right. Finally, the effect of blowing and scattering the conductive rubber strip forward and to the left and right is achieved.

[0030] Finally, the entire blowing component is fixedly installed on the overall frame by the mounting bracket. At the same time, to better adapt to the actual production, the installation angle of the component is adjustable, and the installation angle is controlled by the adjusting plate.

[0031] The working process of the feeding assembly is as follows:

[0032] (1) Manually pour the conductive rubber strip into the material trough of the current-limiting component. The conductive rubber strip is conveyed forward by the first synchronous belt. The current-limiting plate limits the quantity of the conductive rubber strip output to the next component, and then the conductive rubber strip is sent into the scattering component;

[0033] (2) The scattering component drives the brush to reciprocate through a magnetic coupling rodless cylinder to scatter the fed conductive rubber strip. The scattered conductive rubber strip flows into the blowing component from the end of the first synchronous belt; This step is to prevent the conductive rubber strip from clustering together and affecting the feeding effect of the conductive rubber strip;

[0034] (3) In the blowing component, a plurality of high-pressure nozzles are installed using a flow distribution row. The conductive rubber strip is blown away by high-pressure air, and the conductive rubber strip is sent out in a scattered state. At the same time, a linkage structure is designed, powered by a first cylinder, and the high-pressure nozzles swing left and right, finally realizing the function of dispersing and feeding the conductive rubber strip.

[0035] The combing component includes a combing plate, a height-limiting component, a spring connection component, and an angle adjustment frame. The function of this component is to comb the conductive rubber strip from a scattered and disordered state into an orderly state.

[0036] The combing plate of the combing component is rectangular, inclined at 35 - 45 degrees to the horizontal plane, and is arranged at the rear end of the flow distribution row of the blowing component; the surface of the combing plate is longitudinally divided into four regions on average. From the second region to the lower end of the combing plate, first grooves are equally spaced. In each first groove of the third region, second grooves are equally spaced towards the lower end of the combing plate. In each second groove of the fourth region, third grooves are equally spaced towards the lower end of the combing plate;

[0037] The depths of the first groove, the second groove, and the third groove gradually deepen from top to bottom;

[0038] The width of the third groove is adapted to the width of the conductive rubber strip;

[0039] The bottom surface of the combing plate is installed with reinforced aluminum profiles and a vibration motor. The vibration motor provides a vibration force. Coupled with the self-gravity of the conductive rubber strip, the conductive rubber strip slides down from the first region of the combing plate, successively passing through the second, third, and fourth regions. Each time it slides through a region, the probability of sliding into the groove increases until finally all of it slides into the third groove.

[0040] The height-limiting component of the combing component includes two groups of height-limiting crossbars, crossbar adjusters, crossbar adjuster connection plates, L-shaped connection plates, linear bearings, electromagnets, and first springs, as well as a return material box;

[0041] The two groups of height-limiting crossbars are installed above the combing plate and are located at the front end of the second region. Inverted V-shaped height-limiting blocks are sleeved on the height-limiting crossbars. The height-limiting blocks move synchronously with the height-limiting crossbars, knocking down the laterally sliding conductive rubber strip to become a flat sliding;

[0042] On both sides of the front end of the second region of the combing plate, L-shaped connection plates are respectively provided. The lower ends of the L-shaped connection plates are detachably connected to the return material box;

[0043] The two ends of the two groups of height-limiting crossbars are successively sleeved with linear bearings and crossbar adjusters. The crossbar adjusters are installed in six-sided contact with the height-limiting crossbars;

[0044] The linear bearings are fixed to the inner sides of the L-shaped connection plates through their own flange plates;

[0045] The cross-bar adjusting part connecting plate is rectangular or square, and three U-shaped grooves are provided at its upper edge, namely the first U-shaped groove, the second U-shaped groove and the third U-shaped groove;

[0046] A circular through-hole is also provided on the cross-bar adjusting part connecting plate for setting bolts to fixedly connect with the channel-shaped connecting plate; The cross-bar adjusting part connecting plates are arranged oppositely on the inner and outer sides of the channel-shaped connecting plate. The second U-shaped groove on the inner cross-bar adjusting part connecting plate supports the linear bearing, and the second U-shaped groove on the outer cross-bar adjusting part connecting plate supports the height-limiting cross-bar;

[0047] The cross-bar adjusting part is adapted to its connecting plate and the cross-bar, and is strip-shaped, and its length is equal to the width of the cross-bar adjusting part connecting plate; A through-hole is provided in the middle of the cross-bar adjusting part for sleeving the height-limiting cross-bar, and waist-shaped holes are provided on both sides and are equipped with screws; The cross-bar adjusting part is assembled on the outer side surface of the outer cross-bar adjusting part connecting plate and is sleeved on the height-limiting cross-bar;

[0048] The cross-bar adjusting part is used to adjust the height and angle of the height-limiting cross-bar. Loosen the screws on both sides of the cross-bar adjusting part, adjust the height of the height-limiting cross-bar. When adjusting, the screws move up and down in the first U-shaped groove and the third U-shaped groove of the cross-bar adjusting part connecting plate. After adjusting to the appropriate height, tighten the screws to fix the height-limiting cross-bar;

[0049] The electromagnet is installed at the left end of the height-limiting cross-bar, and the first spring is installed at the right end of the height-limiting cross-bar and is fixed to the cross-bar adjusting part through a lock nut;

[0050] The distance between the height-limiting cross-bar and the carding plate is adjusted through the flange plates of the cross-bar adjusting part and the linear bearing itself;

[0051] When the electromagnet at the left end is energized, the height-limiting cross-bar moves to the left. When the electromagnet is de-energized, the spring at the right end makes the height-limiting cross-bar move to the right, and the height-limiting cross-bar is reset;

[0052] When the electromagnet is repeatedly energized and de-energized, the height-limiting cross-bar makes a reciprocating left and right movement. The conductive rubber strip at the edge of the carding plate is pushed into the return material box by the height-limiting cross-bar. When the return material box collects a certain number of conductive rubber strips, then the return material box is removed, and the conductive rubber strips in the return material box are poured back into the material chute.

[0053] The function of the height-limiting component is to knock down the conductive rubber strip that slides down vertically on its side, making it in a lying-down sliding state, which is convenient for sliding into the groove of the carding plate.

[0054] The spring connecting component of the carding assembly is used to connect the carding plate and the angle adjusting frame. The spring connecting component includes an upper mounting plate, a second spring and a lower mounting plate;

[0055] The upper mounting plate is installed on the bottom surface of the carding plate, and the lower mounting plate is installed at the upper end of the angle adjustment frame. A second spring is installed between the lower and upper mounting plates to make them in flexible contact; the four sides of the upper and lower mounting plates are rigidly assembled through bolts, washers and nuts.

[0056] The angle adjustment frame of the carding assembly is used to adjust the inclination angle between the carding plate and the ground. Through angle adjustment testing, the optimal inclination angle of the carding plate, which is 40 degrees, is calculated to enable the conductive rubber strips scattered on the carding plate to slide down more smoothly.

[0057] The angle adjustment frame is composed of a combination of rods. Its longitudinal section is a frame in the shape of a right trapezoid, with an inclined top surface and a long strip-shaped support frame at the bottom. At least two support rods are symmetrically and vertically arranged on both sides of the support frame. The top of the support rod is connected to a U-shaped card slot, and a rotating shaft is fitted in the U-shaped card slot; a connecting rod with an adjustable angle is inclined and fitted in the U-shaped card slot;

[0058] A waist-shaped hole is opened at the assembly position of the connecting rod and the U-shaped card slot. The rotating shaft passes through the waist-shaped hole. After adjusting the angle between the connecting rod and the horizontal plane, the two ends of the rotating shaft are fixed by fasteners;

[0059] The heights of the two support rods are arranged in a trapezoidal decreasing manner. The front end is the first support rod, and the rear end is the second support rod. An expansion rod is sleeved inside the first support rod. A plurality of through holes are equally spaced and opened on the first support rod and the expansion rod, and locking bolts are installed in the plurality of through holes. By adjusting the height of the expansion rod, the inclination of the top surface of the angle adjustment frame can be adjusted, and this inclination is the inclination of the carding plate;

[0060] Between the first support rod and the second support rod, a third support rod, a fourth support rod, etc. can also be equally spaced. Springs are respectively arranged at the tops of the third support rod and the fourth support rod, and the other ends of the springs are connected to the U-shaped card slot.

[0061] When the inclination angle of the carding plate needs to be adjusted, with the U-shaped card slot as the rotation center, adjust the inclination of the connecting rod with respect to the ground, and then adjust the relative height position of the first support rod and the expansion rod, and lock it with a locking bolt. At this time, the inclination of the connecting rod is the inclination of the carding plate.

[0062] The third spring and the fourth spring are used to support the carding plate for inclination angle adjustment within 5 - 10 degrees. If the inclination angle exceeds this range, the corresponding springs need to be replaced.

[0063] The working process of the carding assembly is as follows:

[0064] (1) The conductive rubber strips are scattered by the feeding assembly and fall on the front end of the carding plate;

[0065] (2) The vibrating motor is turned on. The conductive rubber strip is on the inclined combing plate and slides downward under the action of its own gravity and the high-frequency vibration of the vibrating motor.

[0066] (3) When the conductive rubber strip slides to the position of the height-limiting component, the height-limiting block quickly reciprocates to brush and overturn the laterally sliding conductive rubber strip, changing it to a flat-lying sliding mode.

[0067] (4) The conductive rubber strip continues to slide downward along the combing plate. The lower the combing plate, the more the number of grooves, guiding the conductive rubber strip to slide downward along the corresponding grooves.

[0068] (5) The conductive rubber strip slides to the lowermost end of the combing plate and docks with the groove of the buffer plate of the packaging component.

[0069] The packaging component includes a buffer component, a conveying component and a collecting component. The function of this component is to realize the automatic counting and box packaging of a specified number of conductive rubber strips.

[0070] The buffer component of the packaging component includes a buffer plate, a second air cylinder, a pushing plate, a pressing plate and a baffle.

[0071] The buffer plate is equidistantly provided with grooves. Its upper edge is inclined forward and abuts against the bottom of the combing plate, and its bottom edge is provided with a baffle.

[0072] The width of the groove of the buffer plate is equal to the width of the third groove opened in the fourth area of the combing plate and is adapted to the width of the conductive rubber strip.

[0073] The second air cylinder is fixed on the L-shaped air cylinder connecting plate. The output end of the second air cylinder is fixedly connected with a pushing plate. The L-shaped air cylinder connecting plate is fixedly connected with the cross beam of the packaging machine frame.

[0074] The pushing plate is inclined backward and is arranged with a flared opening with respect to the buffer plate.

[0075] Push rods are fixedly arranged at intervals on the pushing plate. The other end of the push rod is fixed on the pressing plate. A spring is sleeved on the push rod. The pressing plate is arranged between the buffer plate and the pushing plate. The two ends of the pushing plate are respectively connected through L-shaped connecting plates. The baffle is connected with the pushing plate through an L-shaped connecting plate. The pressing plate and the baffle are driven by the second air cylinder.

[0076] The pressing plate is used to press the conductive rubber strip falling on the upper part of the buffer plate, and the baffle is used to press the conductive rubber strip falling on the lower part of the buffer plate.

[0077] When the second air cylinder rod extends, it drives the pushing plate to extend. The pushing plate drives the pressing plate to move towards the buffer plate, pressing and holding the conductive rubber strip falling to this position, and at the same time blocking the conductive rubber strip entering the buffer plate from above from continuing to fall. At the same moment, the baffle at the bottom edge leaves the bottom of the buffer plate, enabling the lower rubber strip to automatically fall to the conveying component.

[0078] When the second cylinder rod retracts, it drives the push plate to retract, and the push plate drives the pressure plate to leave the buffer plate, releasing the pressed conductive rubber strip to allow it to fall, allowing the conductive rubber strip that enters the buffer plate from above to continue falling; at the same time, the baffle plate at the bottom edge abuts against the bottom of the buffer plate to prevent the conductive rubber strip from falling to the conveying component.

[0079] The baffle plate and the push plate are connected together by an L-shaped connecting plate and move simultaneously, and are driven by the second cylinder. The pressure plate moves toward the buffer plate, and the baffle plate leaves the bottom of the buffer plate. The pressure plate presses the conductive rubber strip on it, and at the same time, the baffle plate leaves the bottom of the buffer plate, causing the rubber strip below to automatically fall to the conveying component.

[0080] The conveying component of the packaging assembly includes a conveyor belt, a second synchronous belt, a first motor and a second motor;

[0081] The conveyor belt and the second synchronous belt are arranged vertically;

[0082] The conveyor belt is provided with grooves at equal intervals and butted against the bottom edge of the buffer plate, and the conveyor belt is driven by a first motor to perform forward and backward rotational motion;

[0083] The second synchronous belt is provided with grooves at equal intervals, which are connected with the gap of the discharge end of the conveyor belt, and the second synchronous belt is driven by the second motor to rotate left and right;

[0084] There is a horizontal gap between the conveyor belt and the second synchronous belt, and the conductive rubber strip needs to be placed horizontally and needs to cross the gap at a certain speed. The first motor drives the conveyor belt to move, and the conductive rubber strip on the buffer plate falls into the groove of the conveyor belt. The conveyor belt drives the conductive rubber strip to move forward horizontally and obtain an initial horizontal velocity, and then flies into the second synchronous belt.

[0085] The collecting components of the packaging assembly include a counter, a collecting box, a buffer box and a buffer plate;

[0086] One end of the counter is fixed on the frame of the packaging machine, and the other end is arranged above the discharge end of the second synchronous belt;

[0087] The slow-joint box is a rectangle that is connected from top to bottom and is arranged below the right end of the second synchronous belt to ensure that it can be connected to the conductive rubber strip at the discharge end of the second synchronous belt. A rectangular opening is opened on the right outer wall of the slow-joint box, and the slow-joint box is fixedly connected to the frame.

[0088] The buffer plate is installed at the rectangular opening of the right outer wall of the buffer box through a rotating shaft. The size of the buffer plate is adapted to the size of the rectangular opening and the top surface of the buffer box. The buffer plate can rotate 0-180 degrees around the rotating shaft. The buffer plate is outside the right side of the buffer box and is in an open state; the buffer plate is inside the right side of the buffer box and is in a closed state.

[0089] The collection box is a rectangle with a closed bottom and is arranged below the buffer box to ensure that it can receive the conductive rubber strip at the discharge end of the second synchronous belt. The collection box is detachably connected to the frame.

[0090] The volume of the collection box is larger than that of the buffer box.

[0091] After the conductive rubber strip flows from the conveyor belt of the conveying component to the groove of the second synchronous belt, the second motor drives the second synchronous belt to move, and the conductive rubber strip moves as the second synchronous belt rotates. After the conductive rubber strip is counted by the counter, it directly drops into the collection box (at this time, the buffer plate is opened outside and does not play a buffering role). When the counter counts to 500 pieces, the buffer plate rotates 180 degrees and closes. The conductive rubber strips that continue to be sent will accumulate on the closed buffer plate in the buffer box. After the collection box is replaced, the buffer plate is reopened, and the collection of the next box of conductive rubber strips continues.

[0092] The working process of the packaging component is as follows:

[0093] (1) The conductive rubber strip combed by the combing component slides into the buffering component. The buffering component reduces the speed of the conductive rubber strip to 0 and makes the conductive rubber strip at the same height, and then sends the conductive rubber strip into the conveying component.

[0094] (2) The conveyor belt in the conveying component drives the incoming conductive rubber strip to move and gives the conductive rubber strip a certain speed so that the conductive rubber strip can smoothly enter the second synchronous belt with grooves.

[0095] (3) The conductive rubber strip in the second synchronous belt moves to the right following the second synchronous belt, is counted by the counter, and flows to the collection box below. When the number of conductive rubber strips in the collection box reaches 500, the buffer plate closes and the collection box is replaced. After the replacement is completed, the buffer plate is reopened to continue collecting the next box of conductive rubber strips.

[0096] For the automatic box-packaging machine for conductive rubber strips of the present invention, a PLC control system is adopted to precisely control the movement of the cylinder, and a frame connected by profiles is used as a support to ensure the accuracy of the positions of the components installed thereon.

[0097] The automatic box-packaging machine for conductive rubber strips of the present invention can replace manual labor, improve the box-packaging efficiency of conductive rubber strips, ensure product quality at the same time, improve packaging accuracy, and make it more in line with the requirements of the development of modern production enterprises.

[0147] The adjusting plate 3-8 is installed on the back of the blowing device mounting plate 3-4. The adjusting plate 3-8 is connected to the mounting bracket 3-9 of the blowing component through a connecting shaft, and the angle of the blowing device mounting plate 3-4 is controlled by rotating the adjusting plate 3-8;

[0151] The conductive rubber strip drops from the first synchronous belt 1-4 onto the inclined material receiving plate 3-2. Due to inertia and gravitational potential energy, the conductive rubber strip slides down along the material receiving plate 3-2.

[0155] The width of the third groove 5-7 is adapted to the width of the conductive rubber strip;

[0156] The bottom surface of the combing plate 5 is installed with reinforced aluminum profiles and vibration motors. The vibration motors provide vibration force. Coupled with the self-weight of the conductive rubber strip, the conductive rubber strip slides down from the first region 5-1 of the combing plate 5, successively passing through the second region 5-2, the third region 5-3, and the fourth region 5-4. Each time it slides through a region, the probability of sliding into the groove will increase until finally all of them slide into the third groove 5-6.

An inverted V-shaped height-limiting block 4-6-1 is sleeved on the height-limiting crossbar 4-6. The height-limiting block 4-6-1 moves synchronously with the height-limiting crossbar 4-6 to knock over the laterally sliding conductive rubber strip and change it to a lying-down sliding mode;

[0159] Channel-shaped connection plates 4-4 are respectively arranged on both sides of the front end of the second area 5-2 of the carding plate 5. The lower end of the channel-shaped connection plate 4-4 is detachably connected to the return material box 4-7;

[0160] Both ends of the two groups of height-limiting crossbars 4-6 are sequentially sleeved with linear bearings 4-5 and crossbar adjusters 4-2. The crossbar adjuster 4-2 and the height-limiting crossbar 4-6 are installed in six-sided contact;

Loosen the screws on both sides of the crossbar adjuster 4-2, adjust the height of the height-limiting crossbar 4-6. When adjusting, the screws move up and down in the first U-shaped groove 4-3-1 and the third U-shaped groove 4-3-3 of the crossbar adjuster connecting plate 4-3. After adjusting to the appropriate height, tighten the screws to fix the height-limiting crossbar 4-6.

[0167] The distance between the height-limiting crossbar 4-6 and the carding plate 5 is adjusted by the flange plates of the crossbar adjuster 4-2 and the linear bearing 4-5 itself.

[0168] When the electromagnet 4-1 at the left end is energized, the height-limiting crossbar 4-6 moves to the left. When the electromagnet 4-1 is de-energized, the first spring 4-8 at the right end makes the height-limiting crossbar 4-6 move to the right, and the height-limiting crossbar 4-6 is reset.

[0169] When the electromagnet 4-1 is energized and de-energized reciprocally, the height-limiting crossbar 4-6 moves left and right reciprocally. The conductive rubber strip at the edge of the carding plate 5 is pushed into the return material box 4-7 by the height-limiting crossbar 4-6. When the return material box 4-7 collects a certain number of conductive rubber strips, remove the return material box 4-7 and pour the conductive rubber strips in the return material box 4-7 back into the material chute 1-1.

[0170] The function of the height-limiting component 4 is to knock down the conductive rubber strip that slides down sideways and makes it slide down in a lying state, which is convenient for sliding into the groove of the carding plate 5.

The second spring 6-2 is installed between the upper mounting plate 6-1 and the lower mounting plate 6-3 to make them in flexible contact. The four sides of the upper mounting plate 6-1 and the lower mounting plate 6-3 are rigidly assembled through bolts, washers, and nuts.

[0173] Refer to Figure 14 , the angle adjustment frame 7 is used to adjust the inclination angle between the carding plate 5 and the ground. Through angle adjustment testing, calculate the inclination angle of the carding plate 5 so that the conductive rubber strips scattered on the carding plate 5 can slide down more smoothly;

Its longitudinal section is a frame body in the shape of a right trapezoid, with an inclined top surface and a long strip-shaped support frame at the bottom. At least two support rods are symmetrically and vertically arranged on both sides of the support frame, namely the first support rod 7-3 at the front end and the second support rod 7-6 at the rear end.

[0175] A waist-shaped hole is opened at the assembly position of the connecting rod 7-1 and the U-shaped card slot 7-7. The rotating shaft passes through the waist-shaped hole. After adjusting the angle between the connecting rod 7-1 and the horizontal plane, the two ends of the rotating shaft are fixed by fasteners;

[0176] The heights of the two support rods are arranged in a trapezoidal decreasing manner, with the first support rod 7-3 at the front end and the second support rod 7-6 at the rear end. An expansion rod 7-2 is sleeved inside the first support rod 7-3. A plurality of through holes are evenly spaced on the first support rod 7-3 and the expansion rod 7-2, and locking bolts are installed in the plurality of through holes. By adjusting the height of the expansion rod 7-2, the inclination of the top surface of the angle adjustment frame 7 can be adjusted, and this inclination is the inclination of the carding plate 5;

[0177] Between the first support rod 7-3 and the second support rod 7-6, the third support rod 7-4, the fourth support rod 7-5, etc. are evenly spaced. Springs are arranged at the tops of the third support rod 7-4 and the fourth support rod 7-5, and the other ends of the springs are connected to the U-shaped card slot 7-7;

[0178] The spring is used to support the carding plate 5 to adjust the inclination angle within 5-10 degrees. If the inclination angle exceeds this range, the corresponding spring needs to be replaced.

[0179] When the inclination angle of the carding plate 5 needs to be adjusted, with the U-shaped card slot 7-7 as the rotation center, adjust the inclination of the connecting rod 7-1 with respect to the ground, and then adjust the relative height position between the first support rod 7-3 and the expansion rod 7-2, and lock it with a locking bolt. At this time, the inclination of the connecting rod 7-1 is the inclination of the carding plate 5.
