A high-precision fastener packaging and encapsulating device

Abstract

This invention provides a high-precision fastener packaging and encapsulation device, relating to the field of fastener encapsulation technology. It includes a main body with an infeed device at its upper end and a packaging device at its lower end. The device also includes a feeding mechanism comprising a placement frame and a moving plate. When a worker starts a motor, the motor drives a connecting rod and a rotating bevel gear to rotate. Two springs move the moving plate to the left, causing a T-shaped block to move along a T-slot. This movement also pushes the high-precision fastener to the left until it is pushed into the infeed device. The motor then reverses its output, returning the placement frame to its original position. Workers only need to place the high-precision fastener onto the placement frame to feed the fastener, eliminating the need for repeated ladder climbs and improving safety.

Description

Technical Field

[0001] This invention belongs to the field of fastener packaging technology, and more specifically, relates to a high-precision fastener packaging and encapsulation device. Background Technology

[0002] High-precision fastener packaging and sealing equipment is used in automated production lines. It is mainly used to package and seal high-precision fasteners such as screws and nuts. This equipment usually includes functions such as automatic feeding, counting, packaging, sealing and labeling. It can efficiently complete the product packaging process and ensure that the quality and appearance of the product meet the standard requirements.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were discovered: When workers need to pack and seal high-precision fasteners, a large number of high-precision fasteners need to be placed into the feeding device and then packaged and sealed by the sealing device. However, high-precision fasteners are usually metal products, and the feeding port of the device is usually high. Therefore, when workers put a large number of high-precision fasteners into the feeding device, they need to climb a ladder to repeatedly perform the feeding operation, which reduces the safety of the work.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-precision fastener packaging and sealing device in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a high-precision fastener packaging and encapsulation device.

[0006] A high-precision fastener packaging and sealing device includes a main body, an infeed device at the upper end of the main body, and a packaging device at the lower end of the main body. The device also includes a feeding mechanism, comprising a placement frame and a moving plate. The placement frame has a notch at its right end and is located at the right end of the infeed device. The moving plate is located at the left end of the placement frame. Lifting blocks are fixedly connected to both ends of the moving plate. Two grooves are formed on the inner wall of the placement frame, each corresponding to a lifting block. Connecting short rods are installed inside each groove, with their upper ends fixedly connected to the inner wall of the placement frame. Holes are formed through the upper surfaces of both lifting blocks, allowing the placement frame to movably engage with the corresponding lifting block through these holes. Springs are fixedly connected to the lower surfaces of both lifting blocks, with their lower surfaces also fixedly connected to the inner wall of the placement frame. A fixed cover is fixedly connected to the upper surface of the infeed device, and a stop plate is fixedly connected to the right surface of the infeed device, corresponding to the moving plate.

[0007] Preferably, four fixed short plates are provided at the right end of the feeding device. The four fixed short plates are parallel to each other. The front and rear sides of the feeding device are fixedly connected to the two fixed short plates on the left. The lower surface of each fixed short plate is rotatably connected to a threaded rod. The threads on the two threaded rods on the right are symmetrical to the threads on the two threaded rods on the left. A base plate is provided at the lower end of the feeding device. The lower surfaces of the four threaded rods are rotatably connected to the upper surface of the base plate.

[0008] Preferably, lifting plates are fixedly connected to the four corners of the placement frame, and the four lifting plates correspond to the positions of the four fixed short plates. Each lifting plate has a threaded groove through its upper surface, and each lifting plate is threadedly connected to the corresponding threaded rod through the threaded groove.

[0009] Preferably, the lower ends of the two threaded rods located at the rear position are fixedly connected to a rotating bevel gear, and the opposite ends of the two rotating bevel gears are vertically meshed with a meshing bevel gear. A connecting rod is provided between the two meshing bevel gears, and both ends of the connecting rod are fixedly connected to the corresponding meshing bevel gear.

[0010] Preferably, a U-shaped plate is fixedly connected to the upper surface of the base plate, the U-shaped plate corresponds to the position of the connecting rod, and two holes are opened through the right surface of the U-shaped plate. The U-shaped plate is rotatably connected to both ends of the connecting rod through the holes, and a meshing bevel gear is fixedly connected to the midpoint of the connecting rod.

[0011] Preferably, a rotating bevel gear two is perpendicularly meshed at the front end of the meshing bevel gear two, a connecting short rod one is fixedly connected to the front surface of the rotating bevel gear two, and the rear surface of the connecting short rod one is rotatably connected to the connecting rod.

[0012] Preferably, a fixing ring is fixedly connected to the front surface of the U-shaped plate, and a motor is fixedly connected to the front surface of the fixing ring. A hole is opened through the front surface of the U-shaped plate, and the hole corresponds to the position of the connecting short rod. The output port of the motor passes through the hole and is fixedly connected to the front surface of the connecting short rod.

[0013] Preferably, the interior of the placement frame is provided with a movable long plate, the left surface of which is movably connected to the right surface of the movable long plate, and two movable long rods are fixedly connected to the right surface of the movable long plate.

[0014] Preferably, two holes (4) are formed through the right surface of the placement frame, each corresponding to the position of one of the two movable rods. The holes have equal radii. A fixed plate is provided on the right surface of the placement frame, and the right surfaces of the two movable rods pass through the corresponding holes (4) and are fixedly connected to the left surface of the fixed plate.

[0015] Preferably, two springs are fixedly connected to the left surface of the fixed long plate, and the left surfaces of the two springs are fixedly connected to the right surface of the placement frame. The two movable long rods are located inside the two springs. T-blocks are fixedly connected to both ends of the movable long plate. Two T-slots are opened in the inner wall of the placement frame. The placement frame is movably engaged with the two T-blocks through the two T-slots. Sprockets are fixedly connected to the positions of the four threaded rods. Two synchronous chains are provided at the upper end of the base plate. The two synchronous chains are parallel to each other, and the two sprockets on the same side are engaged with the corresponding synchronous chains.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a placement frame is provided. When the operator starts the motor, the motor drives the connecting rod 1 and the rotating bevel gear 2 to rotate. Since the rotating bevel gear 2 meshes with the meshing bevel gear 2, and the meshing bevel gear 2 is fixedly connected to the connecting rod, the rotation of the rotating bevel gear 2 will drive the two meshing bevel gears 1 to rotate. The two meshing bevel gears 1 drive the rotating bevel gear 1 to rotate, and the two rotating bevel gears 1 drive the two threaded rods at the rear end to rotate. At this time, since all four sprockets are meshed with two synchronous chains, the four threaded rods rotate synchronously. When the four threaded rods rotate synchronously, the four lifting plates are connected to the placement frame but do not rotate. At this time, the four lifting plates will drive the placement frame and the moving plate to rise. When the moving plate rises to a certain distance, the abutment plate will abut against the moving plate. This prevents the moving plate from rising further, but the placement frame continues to rise unaffected until the lifting blocks at both ends of the moving plate abut against the inner wall of the placement frame. At this point, the placement frame will stop rising, and an opening will form on the left side of the placement frame, corresponding to the fixed cover. The two springs will then return, causing the moving plate to move to the left. The moving plate will then move the T-shaped block along the T-slot, and the moving plate will also push the high-precision fastener to the left until it is pushed into the feeding device. The motor will then reverse its output, causing the placement frame to return to its original position. Workers only need to place the high-precision fastener onto the placement frame to feed the device, avoiding the need for workers to repeatedly use ladders to feed the device and improving safety.

[0017] In this invention, a movable long plate is provided. When the worker places the high-precision fastener between the movable long plate and the fixed long plate, the fixed long plate is released. At this time, the second spring will rebound. When the second spring rebounds, it will drive the fixed long plate to move to the left. At this time, the movable long plate will also move with the fixed long plate. Therefore, the movable long plate will hold the high-precision fastener. When the placement frame rises, since the high-precision fastener is held by the movable long plate, the high-precision fastener will not have excessive positional displacement, thus improving the stability of the placement frame when it rises.

[0018] In this invention, by providing a fixed short plate, when the placement frame rises, the four lifting plates will also rise. When the placement frame rises to a certain height, the two lifting blocks will abut against the inner wall of the placement frame. At this time, the four lifting plates will abut against the fixed short plate, preventing the placement frame from rising further. This avoids the problem of the two lifting blocks being squeezed and damaged due to excessive rise of the placement frame, and improves the service life of the lifting blocks.

[0019] In this invention, a fixing ring is provided to provide a stable output environment for the motor. When the motor starts, the fixing ring firmly restricts the motor from shifting position, so that the motor cannot move but can only stably drive the connecting short rod and the rotating bevel gear to rotate, thereby improving the stability of the motor when starting.

[0020] In this invention, by providing a U-shaped plate, when the operator controls the motor to output in the reverse direction, the placement frame will gradually descend. When the placement frame descends to a certain distance, the lower surface of the placement frame will abut against the lower surface of the U-shaped plate, preventing the placement frame from descending further. This avoids the problem of the placement frame colliding with the meshing bevel gear two due to the decrease in height, allowing the meshing bevel gear two to stably drive the connecting rod to rotate.

[0023] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0024] Please see Figures 1-8This invention provides a high-precision fastener packaging and sealing device, including a device body 102. A feeding device 101 is located at the upper end of the device body 102, and a packaging device 103 is located at the lower end of the device body 102. The high-precision fastener packaging and sealing device also includes a feeding mechanism, comprising a placement frame 109 and a moving plate 126. A notch is provided at the right end of the placement frame 109, which is located at the right end of the feeding device 101. The moving plate 126 is located at the left end of the placement frame 109. Lifting blocks 130 are fixedly connected to both the front and rear ends of the moving plate 126. Two grooves are formed on the inner wall of the placement frame 109, each corresponding to a position of one of the lifting blocks 130. Each groove contains a... There are two connecting short rods 134, the upper ends of which are fixedly connected to the inner wall of the placement frame 109. Holes 131 are drilled through the upper surfaces of the two lifting blocks 130, allowing the placement frame 109 to movably engage with the corresponding lifting block 130 through the holes 131. Springs 112 are fixedly connected to the lower surfaces of the two lifting blocks 130, and their lower surfaces are fixedly connected to the inner wall of the placement frame 109. A fixed cover 104 is fixedly connected to the upper surface of the feeding device 101, and a stop plate 110 is fixedly connected to the right surface of the feeding device 101. The stop plate 110 corresponds to the position of the moving plate 126. Four fixed short plates 105 are provided at the right end of the feeding device 101. The feeding device 101 is parallel to each other. Both its front and rear sides are fixedly connected to two fixed short plates 105 on the left. A threaded rod 106 is rotatably connected to the lower surface of each fixed short plate 105. The threads on the two threaded rods 106 on the right are symmetrical to those on the two threaded rods 106 on the left. A base plate 117 is located at the lower end of the feeding device 101. The lower surfaces of the four threaded rods 106 are rotatably connected to the upper surface of the base plate 117. When the operator pulls the fixed long plate 107, the fixed long plate 107 moves the movable long plate 108 via the movable long rod 114. At this time, the high-precision fasteners to be packaged and sealed are placed inside the placement frame 109, with the high-precision fasteners located between the movable plate 126 and the movable long plate 108. At this time, the two springs... After the second 113 is stretched and the fixing plate 107 is released, the motor 125 is started. The motor 125 drives the connecting short rod 123 and the rotating bevel gear 122 to rotate. Since the rotating bevel gear 122 meshes with the meshing bevel gear 124, and the meshing bevel gear 124 is fixedly connected to the connecting rod 118, the rotation of the rotating bevel gear 122 will drive the two meshing bevel gears 121 to rotate. The two meshing bevel gears 121 will drive the rotating bevel gear 120 to rotate. The two rotating bevel gears 120 will drive the two threaded rods 106 at the rear end to rotate. At this time, since all four sprockets 136 are meshed with the two synchronous chains 119, the four threaded rods 106 rotate synchronously. When the four threaded rods 106 rotate synchronously...Four lifting plates 115 are connected to the placement frame 109 without rotating. At this time, the four lifting plates 115 will drive the placement frame 109 and the moving plate 126 to rise. When the moving plate 126 rises to a certain distance, the abutment plate 110 will abut against the moving plate 126, preventing it from rising further. However, the placement frame 109 will continue to rise unaffected until the lifting blocks 130 at both ends of the moving plate 126 abut against the inner wall of the placement frame 109. At this point, the placement frame 109 will stop rising, and an opening will form on the left end of the placement frame 109, corresponding to the fixed cover 104. At this time, the two springs... Spring 113 rebounds, and the two springs 113 drive the moving plate 108 to move to the left. The moving plate 108 drives the T-block 111 to move along the T-slot 133. As the moving plate 108 moves, it also pushes the high-precision fastener to the left until it is pushed into the feeding device 101. Then, the control motor 125 reverses its output, causing the placement frame 109 to return to its original position. Workers only need to place the high-precision fastener onto the placement frame 109 to feed the feeding device 101, avoiding the need for workers to repeatedly use ladders to feed the device and improving safety.

[0025] Lifting plates 115 are fixedly connected to the four corners of the placement frame 109. Each of the four lifting plates 115 corresponds to one of the four fixed short plates 105. A threaded groove 135 is formed through the upper surface of each lifting plate 115. Each lifting plate 115 is threadedly connected to a corresponding threaded rod 106 through the threaded groove 135. The lower ends of the two threaded rods 106 located at the rear are fixedly connected to rotating bevel gears 120. The opposite ends of the two rotating bevel gears 120 are perpendicularly meshed with meshing bevel gears 121. A connecting rod 118 is provided between the two meshing bevel gears 121. Both ends of the connecting rod 118 are connected to the corresponding... The meshing bevel gear 121 is fixedly connected. When the operator places the high-precision fastener between the moving long plate 108 and the moving plate 126 and then releases the fixed long plate 107, the spring 113 will rebound. When the spring 113 rebounds, it will drive the fixed long plate 107 to move to the left. At this time, the moving long plate 108 will also move with the movement of the fixed long plate 107. Therefore, the moving long plate 108 will abut against the high-precision fastener. When the placement frame 109 rises, since the high-precision fastener is abutted by the moving long plate 108, the high-precision fastener will not have excessive positional displacement, thus improving the stability of the placement frame 109 when it rises.

[0026] A U-shaped plate 116 is fixedly connected to the upper surface of the base plate 117. The U-shaped plate 116 corresponds to the connecting rod 118. Two holes 129 are opened through the right surface of the U-shaped plate 116. The U-shaped plate 116 is rotatably connected to both ends of the connecting rod 118 through the holes 129. A meshing bevel gear 124 is fixedly connected to the midpoint of the connecting rod 118. A rotating bevel gear 122 is perpendicularly meshed at the front end of the meshing bevel gear 124. A connecting short rod 123 is fixedly connected to the front surface of the rotating bevel gear 122. The rear surface of the connecting short rod 123 is rotatably connected to the connecting rod 118. When the placement frame 109 rises, the four lifting plates 115 also rise. When the placement frame 109 rises to a certain height, the two lifting blocks 130 will abut against the inner wall of the placement frame 109. At this time, the four lifting plates 115 will abut against the fixed short plate 105, so that the placement frame 109 cannot continue to rise. This avoids the problem of the two lifting blocks 130 being squeezed and damaged due to excessive rise of the placement frame 109, and improves the service life of the lifting blocks 130.

[0027] A fixing ring 127 is fixedly connected to the front surface of the U-shaped plate 116, and a motor 125 is fixedly connected to the front surface of the fixing ring 127. A hole 128 is opened through the front surface of the U-shaped plate 116, and the hole 128 corresponds to the position of the connecting short rod 123. The output port of the motor 125 passes through the hole 128 and is fixedly connected to the front surface of the connecting short rod 123. A movable long plate 108 is provided inside the placement frame 109. The left surface of the movable long plate 108 is movably connected to the right surface of the movable plate 126. Two movable long rods 114 are fixedly connected to the right surface of the movable long plate 108. The fixing ring 127 provides a stable output environment for the motor 125. When the motor 125 starts, the fixing ring 127 will firmly restrict the motor 125 from shifting its position, so that the motor 125 cannot move but can only stably drive the connecting short rod 123 and the rotating bevel gear 122 to rotate, thereby improving the stability of the motor 125 when starting.

[0028] Two through holes 132 are formed on the right surface of the placement frame 109, each corresponding to the position of two movable rods 114. The two holes 132 have equal radii. A fixed plate 107 is provided on the right surface of the placement frame 109. The surfaces of the two movable rods 114 pass through the corresponding holes 132 and are fixedly connected to the left surface of the fixed plate 107. Two springs 113 are fixedly connected to the left surface of the fixed plate 107, and the left surfaces of the two springs 113 are fixedly connected to the right surface of the placement frame 109. The two movable rods 114 are located inside the two springs 113. T-blocks 111 are fixedly connected to both ends of the movable plate 108. Two T-slots 133 are formed on the inner wall of the placement frame 109, and the placement frame 109 is movably engaged with the two T-blocks 111 through the two T-slots 133. The positions of the four threaded rods 106 are... The base plate 117 is fixedly connected to a sprocket 136. Two synchronous chains 119 are set at the upper end of the base plate 117. The two synchronous chains 119 are parallel to each other. The two sprockets 136 on the same side are meshed with the corresponding synchronous chains 119. When the operator controls the motor 125 to output in reverse, the placement frame 109 will gradually descend. When the placement frame 109 descends to a certain distance, the lower surface of the placement frame 109 will abut against the lower surface of the U-shaped plate 116, so that the placement frame 109 can not continue to descend. This avoids the problem of the placement frame 109 colliding with the meshing bevel gear 124 due to the decrease in height, so that the meshing bevel gear 124 can stably drive the connecting rod 118 to rotate.

[0029] Working principle: First, the worker pulls the fixed long plate 107, causing it to move the movable long plate 108 via the movable long rod 114. At this time, the high-precision fasteners to be packaged and sealed are placed inside the placement frame 109, with the fasteners positioned between the movable plate 126 and the movable long plate 108. The two springs 113 are stretched. After releasing the fixed long plate 107, the motor 125 is started. The motor 125 drives the connecting short rod 123 and the rotating bevel gear 122 to rotate. Since the rotating bevel gear 122 meshes with the meshing bevel gear 124... Furthermore, the second meshing bevel gear 124 is fixedly connected to the connecting rod 118. Therefore, when the second rotating bevel gear 122 rotates, it will drive the two meshing bevel gears 121 to rotate. The two meshing bevel gears 121 drive the rotating bevel gear 120 to rotate. The two rotating bevel gears 120 drive the two threaded rods 106 at the rear end to rotate. At this time, since all four sprockets 136 are meshed with the two synchronous chains 119, the four threaded rods 106 rotate synchronously. When the four threaded rods 106 rotate synchronously, the four lifting plates 115 are connected to the placement frame 109 and do not rotate. At this time, the four lifting plates 115 will drive the placement frame 109 and the moving plate 126 to rise. When the moving plate 126 rises to a certain distance, the abutment plate 110 will abut against the moving plate 126, preventing the moving plate 126 from rising further. However, the placement frame 109 will not be affected and will continue to rise until the lifting blocks 130 at both ends of the moving plate 126 abut against the inner wall of the placement frame 109. At this time, the placement frame 109 will stop rising. At this time, an opening is formed at the left end of the placement frame 109, and the opening position corresponds to the fixed cover 104. At this time, the two springs 113 rebound, and the two springs 114 return to their original positions. Spring 113 drives the moving plate 108 to move to the left. The moving plate 108 drives the T-block 111 to move along the T-slot 133. When the moving plate 108 moves, it also pushes the high-precision fastener to the left until the high-precision fastener is pushed into the feeding device 101. Then, the control motor 125 outputs in reverse, so that the placement frame 109 returns to its original position. The operator only needs to place the high-precision fastener on the placement frame 109 to feed the feeding device 101, avoiding the need for the operator to repeatedly climb the ladder to feed the feeding device 101, thus improving safety.

[0030] In the second step, after the worker places the high-precision fastener between the movable long plate 108 and the movable plate 126, the fixed long plate 107 is released. At this time, the second spring 113 will rebound. When the second spring 113 rebounds, it will drive the fixed long plate 107 to move to the left. At this time, the movable long plate 108 will also move with the movement of the fixed long plate 107. Therefore, the movable long plate 108 will hold the high-precision fastener. When the placement frame 109 rises, since the high-precision fastener is held by the movable long plate 108, the high-precision fastener will not have excessive positional displacement, thus improving the stability of the placement frame 109 when it rises.

[0031] Third, when the placement frame 109 rises, the four lifting plates 115 also rise. When the placement frame 109 rises to a certain height, the two lifting blocks 130 will press against the inner wall of the placement frame 109. At this time, the four lifting plates 115 will press against the fixed short plate 105, preventing the placement frame 109 from rising further. This avoids the problem of the two lifting blocks 130 being squeezed and damaged due to excessive rise of the placement frame 109, and improves the service life of the lifting blocks 130.

[0032] Fourth, the retaining ring 127 provides a stable output environment for the motor 125. When the motor 125 starts, the retaining ring 127 will firmly restrict the motor 125 from shifting its position, so that the motor 125 cannot move but can stably drive the connecting short rod 123 and the rotating bevel gear 122 to rotate, thus improving the stability of the motor 125 when starting.

[0033] Fifth step: When the operator controls the motor 125 to output in reverse, the placement frame 109 will gradually descend. When the placement frame 109 descends to a certain distance, the lower surface of the placement frame 109 will abut against the lower surface of the U-shaped plate 116, preventing the placement frame 109 from descending further. This avoids the problem of the placement frame 109 colliding with the meshing bevel gear 124 due to the decrease in height, allowing the meshing bevel gear 124 to stably drive the connecting rod 118 to rotate.
