Description

Technical Field

[0001] This utility model relates to the field of pencil production equipment technology, and in particular to a feeding device for a pencil tip machine. Background Technology

[0002] In the pen tip assembly process, the aluminum sleeve needs to be precisely fitted onto the end of the pen barrel; traditional manual feeding is inefficient and has poor positioning accuracy. Nowadays, automated equipment replaces manual labor. Publication number CN210821507U discloses a screw-type pen tip assembly machine, which includes a frame with a pen-dropping mechanism above it. The pencil falls vertically onto a spiral feeding mechanism and is then horizontally conveyed forward by the spiral feeding mechanism. Along the conveying direction of the spiral feeding mechanism, a pencil tip extrusion mechanism, a pencil aluminum sleeve installation mechanism, an aluminum sleeve correction mechanism, and an eraser installation mechanism are sequentially arranged, all facing the end face of the pencil tip. A hopper is located at the front end of the spiral feeding mechanism. This screw-type pen tip assembly machine has a reasonable structure and is safe and efficient. However, the automated equipment still has the following problems: (1) the irregular aluminum sleeves fall laterally in the track and are easy to block the outlet (such as triangular aluminum sleeves); (2) the direction of falling into the steel mouth is unstable (such as the triangular aluminum sleeves with some points pointing up and some pointing down); (3) there is a lack of aluminum sleeve falling auxiliary mechanism, resulting in a high failure rate. Utility Model Content

[0003] (1) Technical solution To solve the above-mentioned technical problems, this utility model provides a feeding device for a pen tip machine, including a frame, a fixed base, a vertical aluminum sleeve straight track, an aluminum sleeve steel nozzle, an aluminum sleeve push rod, a drive mechanism, a detection mechanism, a pen barrel positioning seat, and a cylinder. The fixed base is installed on the frame, and a track fixing rod is fixed horizontally on the top of the fixed base. The vertical aluminum sleeve straight track is vertically installed on the track fixing rod. A pen barrel positioning seat for positioning the pen barrel is installed on the frame on one side of the fixed base. The aluminum sleeve steel nozzle facing the pen barrel positioning seat is provided on the outer wall of one side of the fixed base. A vertical aluminum sleeve inlet is provided on the top of the vertical aluminum sleeve straight track. The lower end of the vertical aluminum sleeve straight track extends above the aluminum sleeve nozzle and has a vertical aluminum sleeve outlet. The middle of the fixed base is horizontally mounted with an aluminum sleeve push rod that can push the aluminum sleeve inside the aluminum sleeve nozzle to the end of the pen barrel. A drive mechanism is mounted on one side of the frame to drive the aluminum sleeve push rod to achieve horizontal reciprocating motion in the aluminum sleeve nozzle. A swing block is mounted on the drive mechanism. A detection mechanism for detecting the swing position of the swing block is mounted on one side of the frame. A cylinder mounting bracket is fixed on the fixed base. The cylinder is mounted obliquely on the cylinder mounting bracket and the piston rod of the cylinder faces the vertical aluminum sleeve outlet.

[0004] Preferably, the driving mechanism includes a swing rod, a first pressing part, a cam, a connecting rod, and a second pressing part. The middle part of the swing rod is hinged to one side of the frame. The cam is installed at the bottom of the frame and driven to rotate by a motor. The lower end of the swing rod is provided with the first pressing part for contacting the cam protrusion. The connecting rod is laterally fixed on the upper end of the swing rod. One end of the connecting rod is provided with the second pressing part for pressing one end of the aluminum sleeve push rod. The swing block is installed on the other end of the connecting rod.

[0005] Preferably, the swing block is T-shaped and its top surface is arc-shaped.

[0006] Preferably, the detection mechanism includes a bracket and a through-beam laser sensor. There are two brackets, which are installed on the frame on both sides of the swing block. The laser emitter and laser receiver of the through-beam laser sensor are respectively installed on the two brackets and are symmetrically distributed.

[0007] Preferably, a controller is mounted on the frame, and the through-beam laser sensor and the cylinder are electrically connected to the controller.

[0008] (2) Beneficial effects This utility model provides a feeding device for a leather head machine. Compared with the prior art, this utility model has the following advantages: (1) The vertical aluminum sleeve is installed vertically on the straight track. The aluminum sleeve falls vertically downward by gravity. The structure is simple and reliable and the feeding is smooth.

[0009] (2) The cam-lever (swing rod)-link (connecting rod) transmission mechanism converts the rotational motion into precise linear reciprocating motion, with large pushing force and controllable motion trajectory, ensuring that the aluminum sleeve is pressed into place.

[0010] (3) The aluminum sleeve and steel nozzle receive the vertically falling aluminum sleeve and guide it, while the pen barrel positioning seat fixes the pen barrel. The two work together to ensure that the aluminum sleeve and the end of the pen barrel are accurately aligned.

[0011] (4) By detecting the position of the swing block linked with the push rod, the key working state of the push rod is indirectly but reliably monitored, providing accurate and effective action signals for the cylinder.

[0012] (5) The inclined cylinder piston rod can be aligned with the vertical aluminum sleeve outlet to provide auxiliary thrust when necessary, effectively solving the problem of the aluminum sleeve getting stuck at the outlet. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, the feeding device for a pencil tip machine according to this utility model includes a frame 1, a fixed base 2, a vertical aluminum sleeve straight track 4, an aluminum sleeve steel nozzle 5, an aluminum sleeve push rod 6, a drive mechanism 7, a detection mechanism, a pen barrel positioning seat 11, and a cylinder 13. The fixed base 2 is installed on the frame 1. A track fixing rod 3 is fixed horizontally on the top of the fixed base 2. The vertical aluminum sleeve straight track 4 is vertically installed on the track fixing rod 3. A pen barrel positioning seat 11 for positioning the pen barrel is installed on the frame 1 on one side of the fixed base 2. The aluminum sleeve steel nozzle 5 is provided on the outer wall of one side of the fixed base 2, facing the pen barrel positioning seat 11, for receiving the aluminum sleeve falling vertically downward from the vertical aluminum sleeve outlet 42. A vertical aluminum sleeve inlet 41 is provided on the top of the vertical aluminum sleeve straight track 4, and the lower end of the vertical aluminum sleeve straight track 4 extends to the aluminum sleeve steel nozzle. Above the 5, there is a vertical aluminum sleeve outlet 42. The middle of the fixed base 2 is horizontally installed with an aluminum sleeve push rod 6 that can push the aluminum sleeve in the aluminum sleeve nozzle 5 to the end of the pen. A drive mechanism 7 is installed on one side of the frame 1 to drive the aluminum sleeve push rod 6 to achieve horizontal reciprocating motion in the aluminum sleeve nozzle 5. A swing block 8 is installed on the drive mechanism 7. A detection mechanism for detecting the swing position of the swing block 8 is installed on one side of the frame 1. A cylinder mounting bracket 12 is fixed on the fixed base 2. The cylinder 13 is inclinedly installed on the cylinder mounting bracket 12 with the piston rod of the cylinder 13 facing the vertical aluminum sleeve outlet 42. The main function of the cylinder 13 is to assist the aluminum sleeve to be smoothly discharged from the vertical aluminum sleeve outlet 42 into the aluminum sleeve nozzle 5 below, or to be used for cleaning in specific situations (such as material jamming).

[0020] The drive mechanism 7 includes a swing rod 71, a first pressing part 72, a cam 73, a connecting rod 74, a second pressing part 75, and a motor. The middle part of the swing rod 71 is hinged to one side of the frame 1. The cam 73 is mounted on the bottom of the frame 1 and is driven to rotate by the motor. The lower end of the swing rod 71 is provided with the first pressing part 72 for contacting the protrusion of the cam 73. The connecting rod 74 is horizontally fixed on the upper end of the swing rod 71. One end of the connecting rod 74 is provided with the second pressing part 75 for pressing one end of the aluminum sleeve push rod 6. The cam 73 is driven by the motor and converts the rotational motion into the linear motion of the push rod through the swing rod 71.

[0021] The swing block 8 is installed on the other end of the connecting rod 74. The swing block 8 is T-shaped with a rounded top surface, which facilitates detection and movement. The detection mechanism includes a bracket 9 and a through-beam laser sensor 10. There are two brackets 9, which are installed on the frame 1 on both sides of the swing block 8. The laser emitter and laser receiver of the through-beam laser sensor 10 are respectively installed on the two brackets 9 and are symmetrically distributed. A controller is installed on the frame 1, and the through-beam laser sensor 10 and the cylinder 13 are electrically connected to the controller. During the movement of the aluminum sleeve push rod 6, the swing block 8 at the end of the connecting rod 74 swings synchronously. The through-beam laser sensor 10 monitors the position of the swing block 8 in real time. These position signals are transmitted to the controller to determine the operating status of the device (which position the action has reached), control the piston rod of the cylinder 13 to extend, assist the aluminum sleeve in overcoming possible friction or jamming, and ensure that the aluminum sleeve is smoothly discharged from the vertical aluminum sleeve outlet 42 and falls into the lower aluminum sleeve steel nozzle 5.

[0022] Working principle: (1) The vibratory feeder sorts and transports the aluminum sleeves to the vertical aluminum sleeve inlet 41 at the top of the vertical aluminum sleeve straight track 4.

[0023] (2) The aluminum sleeve falls vertically downward along the vertical aluminum sleeve straight track 4 under the action of gravity. When the lowest aluminum sleeve reaches the vertical aluminum sleeve outlet 42, it may get stuck due to friction. At this time, the controller can instruct the piston rod of the cylinder 13 to quickly extend and gently push the aluminum sleeve to help it fall completely into the aluminum sleeve steel nozzle 5. Then the piston rod of the cylinder retracts.

[0024] (3) The pen barrel is sent to the pen barrel positioning seat 11 and clamped and fixed, with its end center aligned with the outlet of the aluminum sleeve steel nozzle 5.

[0025] (4) The motor drives the cam 73 to rotate at a constant speed. When the cam 73 convex part rotates to contact the first pressing part 72 (roller) at the lower end of the swing rod 71, it pushes the swing rod 71 to swing counterclockwise around the hinge point.

[0026] (5) The upper end of the swing rod 71 drives the connecting rod 74 and the second extrusion part 75 to move towards the aluminum sleeve push rod 6.

[0027] (6) The second extrusion section 75 pushes the aluminum sleeve push rod 6 to move horizontally to the left, and its front end enters the aluminum sleeve steel nozzle 5, which smoothly pushes the aluminum sleeve to the end of the pen and assembles it in place.

[0028] (7) When the connecting rod 74 moves, it drives the swing block 8 to move synchronously. When it moves to the preset position, it will block the beam of the through-beam laser sensor 10. The signal is fed back to the controller. The controller instructs the piston rod of the cylinder 13 to extend quickly and push the aluminum sleeve to help it fall completely into the steel nozzle 5 of the aluminum sleeve. Then the piston rod of the cylinder retracts.

[0029] (8) The cam 73 continues to rotate, and the convex part leaves the first pressing part 72; under the action of gravity, the return spring (which may be located between the swing rod 71 and the frame) or the cam recess, the swing rod 71 swings back clockwise.

[0030] (9) The connecting rod 74 and the second pressing part 75 move to the right, and the aluminum sleeve push rod 6 retracts under the action of the spring (which can be set between the push rod and the fixed seat) and disengages from the aluminum sleeve steel nozzle 5.

[0031] (10) The pen barrel is removed, the next aluminum sleeve falls into the aluminum sleeve steel nozzle 5, the next pen barrel is in place, and the cycle begins.

[0032] The feeding device for the leather tip machine of this utility model is also applicable to the feeding of leather tips in the next process of aluminum assembly (i.e., leather tip assembly).
