Description

Technical Field

[0001] The invention relates to the technical field of umbrella rib glue coating, in particular to a material feeding and discharging mechanism of an umbrella rib automatic glue coating machine. Background Art

[0002] Umbrella ribs are the skeletons that support umbrellas. In the past, most ribs were made of wood or bamboo. Later, iron, steel, aluminum alloy, electroplated and resin ribs appeared. Most of them are shrinkable ribs, which are light and convenient to carry. In order to improve the wear resistance and corrosion resistance of the ribs and extend the service life of the umbrella, it is often necessary to use an automatic rib glue coating machine to coat the ribs with glue. During the process of coating the ribs with glue, the feeding and discharging mechanism is needed to load and unload the ribs.

[0003] A glass fiber umbrella rib rubber coating equipment with patent publication number CN111645260A includes an automatic feeder, a vertical injection molding machine and an automatic unloader which are arranged side by side in sequence, and an injection mold is arranged on the vertical injection molding machine; the automatic feeder includes a feeder frame, a feeder assembly and a moving assembly, and the feeder assembly and the moving assembly are both arranged on the feeder frame; the automatic unloader includes an unloading frame, an in-mold pickup mechanism for removing the rubber-coated glass fiber umbrella rib from the injection mold, a conveying mechanism, a flushing nozzle mechanism for separating the water outlet from the rubber-coated glass umbrella rib, and a finished product handling mechanism, and the in-mold pickup mechanism, the conveying mechanism, the flushing nozzle mechanism and the finished product handling mechanism are all arranged on the unloading frame, and the conveying mechanism conveys the rubber-coated umbrella rib to the bottom of the flushing nozzle mechanism for punching and then conveys it to the handling mechanism.

[0004] In the scenario of small batch or diversified production, the feed and discharge mechanism of the automatic glue coating machine for umbrella ribs of the above and similar principles is not flexible enough and cannot quickly adapt to products of different specifications. That is, when dealing with the glue coating processing of small batches of umbrella ribs, different umbrella ribs have different customer needs, and their rib sizes and glue coating locations are different. If the feed and discharge mechanism of the automatic glue coating machine for umbrella ribs is not flexible enough and cannot be applied to the scenario of small batch or diversified production, it will lead to the manufacturer's ability to respond to market changes. Reduced, unable to meet customer demand for new products or customized products in a timely manner, thereby affecting customer satisfaction and market competitiveness, at the same time, when the umbrella ribs are glued, an injection molding machine mold is often used in conjunction with an injection molding machine for glue coating treatment, and then after the glue coating treatment is completed, the glue coating of the umbrella ribs will remain residual materials from the injection molding. In the scenario of small batch or diversified production, the locations where the residual materials are produced are different. Failure to remove the residual materials will affect the production efficiency of subsequent umbrella rib processing, and thus the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the process of gluing the ribs of the umbrella, an inlet and outlet mechanism of the automatic gluing machine for the ribs is required. The inlet and outlet mechanism provided by the present invention is specially used for adapting to the inlet and outlet operations of ribs of different specifications and different gluing requirements. In the process of using this mechanism for inlet and outlet operations, it is necessary to power the components that need power in the mechanism in advance, and at the same time ensure whether the liquid to be used in the storage box 304 and the storage tank 601 is sufficient, so as to ensure the normal operation of the mechanism.

[0035] like Figure 1-Figure 12As shown, the present invention provides a technical solution: the feeding and discharging mechanism of the automatic glue coating machine for umbrella ribs comprises a support frame 1 and a plurality of support components mounted on the support frame 1 for providing feeding and discharging for a single umbrella rib, the support component comprises an adjusting mechanism 2 mounted on the support frame 1 for adjusting the position of the umbrella rib, both ends of the adjusting mechanism 2 are equipped with a detachable limiting mechanism 4 for fixing and limiting the umbrella ribs, the limiting mechanism 4 is equipped with a filling mechanism 6 for fixing and limiting umbrella ribs of different shapes, the adjusting mechanism 2 is equipped with an auxiliary mechanism 3 for grinding and assisting in glue coating the umbrella ribs, and the limiting mechanism The structure 4 includes a horizontal plate 401, and mounting plates 406 are installed at both ends of the bottom outer wall of the horizontal plate 401. The mounting plates 406 are provided with through grooves 407. A second screw slide assembly 402 driven by a limit motor is installed on the top outer wall of the horizontal plate 401. The screw in the second screw slide assembly 402 is a bidirectional threaded rod. The two slides in the second screw slide assembly 402 are respectively located at both ends of the bidirectional threaded rod. A moving block 403 is installed on the slide portion of the second screw slide assembly 402. A square frame 404 is installed on the moving block 403. A hollow portion of the square frame 404 is installed. There is a semi-circular block 408 facing the center of the second screw slide assembly 402, a rubber sleeve 409 is installed on the inner wall of the semi-circular block 408, a receiving tube 412 connected to the rubber sleeve 409 is embedded and installed on the outer wall of the semi-circular block 408, a valve is installed on the receiving tube 412, a filling mechanism 6 for connecting the receiving tube 412 to fill the rubber sleeve 409 until it fits the umbrella rib is installed on the moving block 403, a rotating mechanism 8 for driving the two merged semi-circular blocks 408 to rotate is installed on the moving block 403, and the second screw slide assembly 402 and the moving block 403 are installed with a rotating mechanism 8 for rotating the semi-circular blocks 408. The buffer reset mechanism 7 for cushioning the umbrella ribs is used to feed the umbrella ribs that need to be coated with rubber onto the limiting mechanism 4. The umbrella ribs are cushioned and reset by the buffer reset mechanism 7. The limiting motor drives the slide in the second screw slide assembly 402 to move until the two semi-annular blocks 408 are merged. The merged two semi-annular blocks 408 wrap the umbrella ribs inside. The filling mechanism 6 fills the rubber sleeve 409 until the rubber sleeve 409 tightly fits the umbrella ribs to complete the fixed limiting of the umbrella ribs. The two semi-annular blocks 408 are driven to rotate by the rotating mechanism 8, and the rotation of the umbrella ribs is completed under the action of the rubber sleeve 409.

[0036] It should be noted that when the ribs need to be coated with glue, the ribs are first placed in the limiting mechanism 4 on the adjusting mechanism 2 through the unloading mechanism of the conveyor belt or the robot. When the ribs are unloaded, there may be a height difference, and the ribs will collide with the limiting mechanism 4. The buffer reset mechanism 7 is provided to buffer the downward pressure generated by the ribs, so as to achieve the effect of protecting the ribs. After the buffering of the ribs is completed, the position of the ribs is fixed and limited by the limiting mechanism 4, and then the position of the limiting mechanism 4 is adjusted by the adjusting mechanism 2, so that the position of the ribs for coating with glue can be adjusted, which is conducive to meeting the requirements of different coating positions. When the limiting mechanism 4 is used to fix the ribs, the bidirectional threaded rod in the second screw slide assembly 402 is driven to rotate by starting the limiting motor, so as to drive the slide in the second screw slide assembly 402 to move, and then adjust the spacing between the two moving blocks 403, and move the two moving blocks 403 to fit the semi-annular blocks 408 on the two moving blocks 403, and wrap the ribs inside. The initial limit can be completed. By setting the rubber sleeve 409 and the receiving tube 412 in cooperation with the filling mechanism 6, the rubber sleeve 409 can be filled with fluid, liquid or gas, so that the rubber sleeve 409 expands to fit closely with the umbrella ribs, and the fixed limit of the umbrella ribs can be completed. By making the rubber sleeve 409 expand and fit closely with the umbrella ribs, the umbrella ribs are fixed and limited, so that the fixed limit is suitable for umbrella ribs of different specifications and shapes, which is convenient for use and avoids errors in the rubber encapsulation due to movement when the umbrella ribs are encapsulated. The rotating mechanism 8 can drive the combined semi-annular block 408 to rotate, and drive the ribs to rotate when the rubber sleeve 409 is tightly fitted with the ribs. By driving the ribs to rotate, the specific part of the ribs that are semi-rubber-coated can be automatically adjusted when the injection mold is used to semi-rubber-coated the ribs, which is convenient for use. At the same time, combined with the auxiliary mechanism 3, after the rubber coating is completed, the auxiliary mechanism 3 provides grinding to cooperate with the rotation of the ribs, so that the rubber-coated part of the ribs can be polished to remove excess materials, so that the rubber-coated part of the ribs is smooth and convenient for use.

[0037] like Figure 2 and Figure 3As shown, the adjustment mechanism 2 includes a track block 201 installed on the support frame 1, and a first screw slide assembly 202 driven by a driving motor is embedded in the bottom of the track block 201. The screw in the first screw slide assembly 202 is a bidirectional threaded rod. The two slides in the first screw slide assembly 202 are respectively located at the two ends of the bidirectional threaded rod. Both ends of the track block 201 are slidably connected with sliding blocks 203, and the sliding blocks 203 are fixedly connected to the slides of the first screw slide assembly 202. Insert blocks 205 and ear plates 206 are respectively installed on the top and middle of the outer walls of both ends of the sliding block 203. The ear plates 206 and the plug block 205 are plugged with a vertical rod 204, a circular plate 208 is installed on the bottom outer wall of the vertical rod 204, a limit spring 207 surrounding the vertical rod 204 is installed between the top outer wall of the circular plate 208 and the bottom outer wall of the ear plate 206, positioning grooves 210 are opened at the bottom of the outer walls of both ends of the sliding block 203, and a positioning block 209 inserted in the positioning groove 210 is installed on the circular plate 208. The horizontal plate 401 is placed on the top of the sliding block 203, and the vertical rod 204 passes through the ear plate 206 and the plug block 205 and is plugged in the through groove 407 to complete the fixing of the limit mechanism 4 on the sliding block 203.

[0038] It should be noted that when the position of the umbrella rib needs to be adjusted, the bidirectional threaded rod in the first screw slide assembly 202 is driven to rotate by starting the driving motor, thereby driving the slide in the first screw slide assembly 202 to move, so that the distance between the two limiting mechanisms 4 on the first screw slide assembly 202 can be adjusted. The limiting effect is applied to the umbrella rib by a single limiting mechanism 4, which drives the umbrella rib to move, and the rubber-coated part of the umbrella rib can be adjusted, which is convenient for use. At the same time, after the rubber coating is completed, the rubber-coated umbrella rib can be unloaded under the action of gravity by the same position adjustment method. By setting the inverted first screw slide assembly 202, the operating efficiency of the first screw slide assembly 202 can be improved, and impurities can be prevented from falling into the first screw slide assembly 202 and affecting the operation of the first screw slide assembly 202. 5. The ear plate 206, the vertical rod 204, the circular plate 208, and the limit spring 207 cooperate with the through groove 407 on the mounting plate 406, so that the single limit mechanism 4 can be easily disassembled, which is beneficial for subsequent maintenance personnel to maintain and repair the limit mechanism 4. At the same time, when a single limit mechanism 4 is damaged, the single limit mechanism 4 can also be quickly replaced, which is convenient for use. During the disassembly process, the staff presses the circular plate 208 downward to deform the limit spring 207, and at the same time, the vertical rod 204 is pulled out of the through groove 407 in the mounting plate 406, and then the limit mechanism 4 is moved to the left or right to remove the limit mechanism 4. Conversely, the limit mechanism 4 can be reinstalled. The installation process is simple and fast, which is convenient for use. By setting the positioning groove 210 and the positioning block 209, the circular plate 208 can only move up and down, which plays a positioning role and is convenient for use.

[0039] like Figure 2 As shown, the auxiliary mechanism 3 includes an electric slide rail 301 installed on the outer walls of both sides of the track block 201, the distance between the electric slide rail 301 and the track block 201 is a spacing groove 5, an L-shaped block 302 is installed on the slider in the electric slide rail 301, a lifting component is embedded and installed on the top of the L-shaped block 302, a first electric push rod 303 facing the middle of the track block 201 is installed on the lifting component, a grinding block 306 is installed at one end of the piston rod of the first electric push rod 303, and an auxiliary component for improving the rubber coating quality of the umbrella ribs is installed on the first electric push rod 303.

[0040] It should be noted that when the auxiliary mechanism 3 is needed, the position of the L-shaped block 302 can be adjusted by means of the electric slide rail 301 in cooperation with the slider, and the height of the grinding block 306 can be increased by means of the lifting assembly in the L-shaped block 302. The depth of the grinding block 306 can be adjusted by means of the first electric push rod 303 to suit the grinding requirements of rubber bags of different thicknesses. The lifting assembly is a component that provides a lifting function, which can specifically be an electric push rod.

[0041] like Figure 2 As shown, the auxiliary component includes a storage box 304 installed on the top outer wall of the first electric push rod 303, a spray head 307 is installed on the top outer wall of the first electric push rod 303 at the top of the grinding block 306, an infusion tube 305 is installed between the spray head 307 and the storage box 304, and a liquid pump is installed on the infusion tube 305. The liquid pump transports the liquid stored in the storage box 304 to the spray head 307 through the infusion tube 305, and the liquid is sprayed onto the umbrella ribs through the spray head 307.

[0042] It should be noted that when the ribs are encapsulated with rubber using an injection mold, a surfactant can be stored in the storage box 304. By starting the liquid pump, the surfactant is transported to the spray head 307 through the infusion tube 305, and then sprayed by the spray head 307 onto the surface of the ribs that need to be encapsulated with rubber. Using non-ionic or anionic surfactants to spray on the surface of the ribs can help reduce surface tension and increase the affinity between the rubber and the ribs. The specific liquid to be sprayed can be determined according to actual usage.

[0043] like Fig.11 As shown, the auxiliary component includes an exhaust fan 9 installed on the top outer wall of the first electric push rod 303, and an air nozzle 11 is installed on the top outer wall of the first electric push rod 303 at the top of the grinding block 306. A first air pipe 10 is installed between the air nozzle 11 and the exhaust fan 9. The air is extracted by the exhaust fan 9 and the first air pipe 10 and transported to the air nozzle 11, and the umbrella ribs are blown and cleaned through the air nozzle 11.

[0044] It should be noted that before the ribs are rubber-wrapped, the exhaust fan 9 is started to extract gas, and the gas is transported to the nozzle 11 through the first gas pipe 10. The nozzle 11 sprays the gas onto the surface of the ribs, so as to clean the surface of the ribs and improve the effect and efficiency of the subsequent rubber wrapping. The two auxiliary components are selected according to actual usage or use requirements.

[0045] like Figure 7 and Fig.10 As shown, the filling mechanism 6 includes a storage tank 601 installed on the moving block 403, a delivery pipe 602 is installed on the storage tank 601, a pump 603 is installed on the delivery pipe 602, a second electric push rod 604 is installed on the storage tank 601, one end of the piston rod of the second electric push rod 604 is fixedly connected to the connecting block, and the connecting block is fixedly connected to the outer wall of the delivery pipe 602.

[0046] It should be noted that when the filling mechanism 6 needs to be used, the storage tank 601 can store fluid or liquid, and the fluid or liquid stored in the storage tank 601 is delivered to the rubber sleeve 409 through the delivery pipe 602 and the receiving pipe 412 by the pump 603 to fill the rubber sleeve 409 until the rubber sleeve 409 expands and fits the umbrella ribs. The second electric push rod 604 can be used to adjust whether the delivery pipe 602 is plugged into the receiving pipe 412. When delivery is required, the delivery pipe 602 is adjusted to be plugged into the receiving pipe 412 by the second electric push rod 604. When delivery is completed or no delivery is required, the delivery pipe 602 is adjusted to be pulled out of the receiving pipe 412 by the second electric push rod 604 to avoid affecting the operation of the rotating mechanism 8.

[0047] like Fig.12 As shown, the filling mechanism 6 includes a pumping air pump 12 installed on the moving block 403, a second air pipe 14 is installed on the pumping air pump 12, a lifting assembly 13 is installed on the pumping air pump 12, a connecting rod is fixedly connected to the piston rod of the lifting assembly 13, and the connecting rod is fixedly connected to the outer wall of the second air pipe 14.

[0048] It should be noted that when the filling mechanism 6 is needed, the second air pipe 14 is inserted into the receiving tube 412 by starting the lifting component 13, and the rubber sleeve 409 is inflated by starting the air pump 12 so that the rubber sleeve 409 expands and fits with the umbrella ribs. When the delivery is completed or no delivery is needed, the second air pipe 14 is adjusted by the lifting component 13 until it is pulled out of the receiving tube 412 to avoid affecting the operation of the rotating mechanism 8. The use of liquid or fluid to expand the rubber sleeve 409 can increase friction and enhance the limiting effect. The use of gas to expand the rubber sleeve 409 is more cost-effective. The selection of the two filling mechanisms 6 is determined according to actual usage.

[0049] like Figure 5-Figure 6As shown, the buffer reset mechanism 7 includes a baffle plate 701 installed on the top outer wall of the second screw slide assembly 402, an arc groove is opened in the middle of the baffle plate 701, a notch is opened on the moving block 403, the baffle plate 701 is located in the notch, the four corners of the top outer wall of the second screw slide assembly 402 are opened with vertical grooves, a damping rod 707 is installed in the vertical groove, and a damping spring 706 surrounding the outer wall of the damping rod 707 is installed between the vertical groove and the baffle plate 701. A hydraulic cylinder 705 is installed on the outer wall, and an arc plate 704 is installed at one end of the piston rod of the hydraulic cylinder 705. The position of the arc plate 704 corresponds to the arc groove. Brackets 702 are installed on the outer walls on both sides of the moving block 403. A displacement block 703 is installed between the brackets 702. The displacement block 703 is a right-angled trapezoid. The displacement block 703 is driven by the movement of the moving block 403 to move and be inserted between the top outer wall of the second screw slide assembly 402 and the baffle plate 701, thereby canceling the elastic force of the shock-absorbing spring 706.

[0050] It should be noted that, by providing the shielding plate 701, the contact range with the umbrella ribs can be increased. When the umbrella ribs fall into the limiting mechanism 4, they will first fall onto the shielding plate 701. By means of the damping rod 707 on the shielding plate 701 and the cushioning spring 706, a buffering effect can be played when the umbrella ribs fall onto the shielding plate 701, thereby preventing the surface of the umbrella ribs from being damaged due to excessive impact force. At the same time, the shielding plate 701 can be made of rubber material, and the umbrella ribs can be concentrated by providing the arc groove. When the buffering is completed, the umbrella ribs can be started. The hydraulic cylinder 705 is dynamically arranged to drive the arc plate 704 to move upward, and then the umbrella ribs can be moved upward. The umbrella ribs can be reset by moving the position to the middle of the two semi-annular blocks 408 in the limiting mechanism 4. When the moving block 403 moves, the bracket 702 and the displacement block 703 are driven to move. By inserting the displacement block 703 into a right-angled trapezoid, the elastic force of the shock-absorbing spring 706 can be cancelled when the displacement block 703 is inserted between the top outer wall of the second screw slide assembly 402 and the baffle plate 701.

[0051] like Figure 7 As shown, the rotating mechanism 8 includes half bearings 801 installed on the inner walls on both sides of the square frame 404, the rotatable inner walls of the half bearings 801 are fixedly connected to the outer wall of the semi-annular block 408, a half gear ring 802 is installed in the middle of the outer wall of the semi-annular block 408, and a gear 803 driven by a rotating motor and meshing with the half gear ring 802 is installed on the moving block 403.

[0052] It should be noted that when the semi-annular blocks 408 on the two limiting mechanisms 4 are fitted, their half bearings 801 and half toothed rings 802 are all fitted. Through the two merged half bearings 801, a rotating platform can be provided for the two semi-annular blocks 408 in the square frame 404. By starting the rotating motor, the gear 803 is driven to rotate, and then through the half toothed ring 802 with the inner core of the gear 803, the merged half toothed ring 802 can be driven to rotate, and then the two merged semi-annular blocks 408 are driven to rotate. In order to improve the tightness during rotation, grooves and mounting protrusions can be opened on the cross-section of the rotatable inner wall of the half bearing 801. When the two half bearings 801 are fitted, the protrusions are inserted into the grooves to improve the tightness during rotation.

[0053] like Figure 4 , Figure 8 and Fig. 9 As shown, the top and bottom of the outer wall of the fitting surface of one of the semi-annular blocks 408 in the limiting mechanism 4 are provided with strip grooves 410, the top and bottom of the outer wall of the fitting surface of the other semi-annular block 408 in the limiting mechanism 4 are fixedly connected with strip blocks 411 adapted to the strip grooves 410, and an inclined block 405 is installed on the top outer wall of the square frame 404.

[0054] It should be noted that when the two semi-annular blocks 408 are fitted together, the strip groove 410 will be inserted into the strip block 411. By setting the strip groove 410 and the strip block 411, the tightness of the combination of the two semi-annular blocks 408 can be improved, which is conducive to improving the rotation effect. By setting the inclined block 405, it can play a guiding role for the umbrella ribs falling into the limiting mechanism 4.
