Description

Technical Field

[0001] The invention relates to a conveyor, in particular to a conveyor used for producing water-based pens. Background Art

[0002] A water-based pen is a writing tool that is widely popular for its convenience, cleanliness and smooth writing. Compared with traditional water-based pens and oil-based pens, direct-liquid water-based pens have a smoother, softer and brighter writing experience, and have become the choice of more and more people. When producing and processing water-based pens, conveyors are indispensable equipment, which complete the transportation and production of water-based pens through conveyors.

[0003] In the traditional production process, the pen barrel on the water-based pen is transported by a conveyor to insert the pen core into the pen barrel and install the pen cover and the pen cap. Most conveyors can only complete the transportation of pen barrel parts. Due to the high equipment cost, the processing equipment will be set separately from the conveyor. After a batch of pen barrel parts are transported, it is necessary to wait for the corresponding processing steps to be completed before continuing to transport the water-based pens. Because it is difficult to coordinate with the production equipment for intermittent and continuous transportation, the waiting time for the transportation of the pen barrel will be prolonged, which will affect the production efficiency of the water-based pen. After the water-based pen is produced, it is necessary to use another equipment to complete the unloading of the water-based pen, which is difficult to be integrated and synchronized. During the unloading process, errors are prone to occur.

[0004] Based on this, in order to solve the above-mentioned technical defects, a conveyor for water-based pen production is now proposed. Summary of the invention

When the water-based pen is produced, the pen barrel 106 will be loaded to the loading assembly through the loading assembly. On the discharge barrel 105, a motor 201 is installed in the middle of the top of the bottom frame 1 by bolts, and the motor 201 is electrically connected to the controller 101. A conveying member 202 is connected to the output shaft of the motor 201. A plurality of groups of push rods 203 are evenly spaced along the circumference of the bottom of the turntable 104. Each group of push rods 203 consists of two. The middle part of the conveying member 202 is semi-annular, and the front and rear ends of the semi-annular part are arc-shaped. Through the rotation of the conveying member 202, a group of push rods 203 can be intermittently pushed to move. An eccentric disk 304 is connected to the rear end of the output shaft of the motor 201, and a transmission rod 305 is rotatably connected to the eccentric part of the left side of the eccentric disk 304. A discharge assembly is provided on the left rear side of the top of the bottom frame 1, and the left end of the transmission rod 305 is rotatably connected to the discharge assembly. An ejection assembly is provided on the turntable 104.

[0035] like Figure 1 and Figure 6-Figure 8 As shown, the unloading assembly includes a guide rail 301, a movable frame 302, an electric clamp 303 and a rotating assembly. The guide rail 301 is connected to the left rear side of the top of the bottom frame 1 by bolts, the movable frame 302 is slidably connected to the guide rail 301, the electric clamp 303 is rotatably connected to the upper side of the movable frame 302, the electric clamp 303 is electrically connected to the controller 101, the left end of the transmission rod 305 is rotatably connected to the movable frame 302, and a rotating assembly is provided on the left side of the top of the bottom frame 1.

[0036] like Figure 1 and Figure 6-Figure 8 As shown, the rotating assembly includes a support rod 401, a rack 402 and a gear 403. The support rod 401 is connected to the top of the bottom frame 1 located on the left side of the guide rail 301, and the upper end of the support rod 401 is connected to the rack 402. The movable frame 302 is slidably connected to the rack 402. The rear end of the electric clamp 303 is connected to the gear 403, and the gear 403 is meshed with the rack 402.

[0037] like Figure 1 and Figure 9-12As shown, the ejection assembly includes a wedge block 501, a guide frame 502, a rubber strip 5021, a fixing member 503, an elastic member 504, a push rod 505 and a conical cylinder 506. The fixing member 503 is welded on the lower side of the turntable 104, and a plurality of elastic members 504 are evenly connected to the upper edge of the fixing member 503. The elastic members 504 are located below each group of discharge barrels 105. Each group of discharge barrels 105 is slidably connected with a push rod 505. The push rod 505 moves upward to eject the water-based pens formed in the two discharge barrels 105 of each group. The elastic member 504 contacts and cooperates with the push rod 505. The right side of the lower part of the movable frame 302 is connected to the wedge block 501 by bolts. The wedge block The inclined surface of 501 faces upward, and the wedge block 501 moves to the right to contact the elastic member 504 and the push rod 505. The right side of the rack 402 is connected to a guide frame 502, and the front part of the guide frame 502 is a U-shaped structure. The produced water-based pens are moved up and ejected and limited by the guide frame 502 to ensure the stability of the water-based pens. A conical cylinder 506 is connected to the inner side of each discharge barrel 105. The conical cylinder 506 is a structure that is narrow at the bottom and wide at the top, and can clamp and limit the pen barrel 106 placed in the conical cylinder 506 to prevent the pen barrel 106 from shaking. The front and rear sides of the U-shaped structure on the guide frame 502 are connected to rubber strips 5021, and the rubber strips 5021 are used to limit the produced water-based pens.

[0038] When producing water-based pens, conveying production is completed by conveyor. The loading component is assembled at the front side of the turntable 104 to complete the loading of the pen barrel 106, while the back side needs to complete the loading of the pen core and ink, and the pen cap and pen cover need to be installed at the same time. According to production needs, corresponding processing equipment is installed at various positions along the circumference. The position on the left side of the turntable 104 is used to complete the unloading of the produced water-based pens through the unloading component. The controller 101 can control the operating time of each device. The electric clamp 303 sets the working program through the controller 101, and will be set according to the operating time of the motor 201. When working, the controller 101 is operated to start the motor 201, and the rotation of the output shaft of the motor 201 will drive the conveying member 202 The rotation of the conveying member 202 will drive the push rod 203 to rotate intermittently. The two discharge barrels 105 of each group are one station. Every time the conveying member 202 rotates one circle, the push rod 203 is pushed to the next station through the arc surface of the front and rear sides. The semi-ring part in the middle of the conveying member 202 limits the two push rods 203 on each group. The turntable 104 rotates intermittently, and the pen barrel 106 can be intermittently loaded through the loading equipment. The turntable 104 will rotate counterclockwise, and the pen barrel 106 will be intermittently transported through the turntable 104, and the ink will be loaded and the pen shell and pen cap will be installed. When the output shaft of the motor 201 rotates, the eccentric disk 304 is driven to rotate at the same time. The eccentric disk 304 rotates one circle and pulls the transmission rod 305 to move back and forth left and right. The transmission rod 305 moves to the right The movement will pull the moving frame 302 and the electric clamp 303 to move to the right, thereby driving the gear 403 to move to the right. The gear 403 will rotate due to the meshing with the rack 402, thereby driving the electric clamp 303 to rotate 90 degrees, so that the clamping piece on the electric clamp 303 faces the turntable 104. At the same time, the moving frame 302 moves to the right and drives the wedge block 501 to move to the right. During the gap when the turntable 104 rotates intermittently, the inclined surface of the wedge block 501 contacts the elastic member 504 and the push rod 505, thereby pushing the push rod 505 upward, and the elastic member 504 is deformed. The upward movement of the push rod 505 will push the water-based pens in the two discharge barrels 105 on this station upward, and the guide frame 502 and the rubber strip 5021 play the role of limiting the water-based pens. The electric clamp 303 will automatically clamp the two water-based pens, and then push the movable frame 302 to move to the left and reset through the transmission rod 305. The movable frame 302 will drive the electric clamp 303 and the gear 403 to move to the left. The electric clamp 303 clamps the water-based pen and moves to the left. The wedge block 501 moves to the left with the movable frame 302. The wedge block 501 no longer resists the push rod 505 and the elastic member 504. The elastic member 504 will rebound and reset, thereby pushing the push rod 505 to move down and reset. The turntable 104 will continue to drive the discharge barrel 105 to transport intermittently. The gear 403 moves to the left and resets, which will reverse and reset due to the rack 402, driving the electric clamp 303 to reverse and reset, so that the clamping member on the electric clamp 303 faces downward.After the moving frame 302 is completely reset, the electric clamp 303 will automatically release the clamping of the water-based pen, and the water-based pen will fall down onto the discharge hopper 102, and then slide forward along the discharge hopper 102. The staff can collect the water-based pen. In this way, the transportation and unloading of the pen holder 106 can be integrated through the cooperation of the eccentric disk 304 and the transmission rod 305. When each finished product moves to the work station on the left, it can be automatically unloaded by the electric clamp 303. At the same time, the wedge block 501 cooperates with the push rod 505. When the electric clamp 303 clamps the finished product, the finished product can be pushed out of the discharge barrel 105, so that the entire water-based pen production work can be carried out in an orderly manner. After the work is finished, the power supply of this device can be turned off.

[0039] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 13-Figure 15 As shown, the conveyor also includes a protrusion 601, a support frame 602, an extrusion piece 603, a tension spring 604 and a pulley 605. A plurality of protrusions 601 are welded at even intervals along the circumference of the outer side of the bottom of the turntable 104, and each protrusion 601 corresponds to each group of discharge barrels 105. The right side of the top of the bottom frame 1 is connected to the support frame 602 by bolts, and the support frame 602 is slidably connected with an extrusion piece 603 for extruding the pen holder 106. A tension spring 604 is connected between the extrusion piece 603 and the support frame 602, and the lower side of the extrusion piece 603 is rotatably connected with the pulley 605. The side of the protrusion 601 facing the counterclockwise direction is inclined, and the protrusion 601 will contact the pulley 605 when it rotates counterclockwise, and the protrusion 601 pushes the pulley 605 downward.

[0040] The front side of the turntable 104 is equipped with a feeding device to complete the preliminary feeding of the pen barrel 106. The turntable 104 rotates counterclockwise to intermittently transport the pen barrel 106. The extrusion piece 603 is located on the right side of the turntable 104. After the pen barrel 106 is initially fed into the discharge barrel 105, the pen barrel 106 is squeezed by the extrusion piece 603 to ensure that the pen barrel 106 is completely inserted into the discharge barrel 105 to avoid the pen barrel 106 being stuck on the inner wall and affecting the subsequent processing. When the turntable 104 rotates intermittently, the protrusion 601 is driven to rotate. When the inclined surface of the protrusion 601 contacts the pulley 605, the pulley 605 is squeezed to move downward. The extrusion piece 603 moves downward, and the tension spring 604 stretches. The extrusion piece 603 will squeeze the two pen holders 106 on the work station, so that the pen holder 106 is completely inserted into the discharge barrel 105. The turntable 104 continues to rotate to drive the protrusion 601 to rotate. The inclined surface of the protrusion 601 passes over the pulley 605, and the tension spring 604 will rebound and reset, driving the extrusion piece 603 and the pulley 605 to move upward and reset. The extrusion piece 603 is separated from the contact with the pen holder 106. In this way, the turntable 104 drives the protrusion 601 to rotate intermittently, and the pen holder 106 moved to the right work station can be squeezed through the extrusion piece 603.

[0041] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
