Description

Technical Field

[0001] The utility model relates to cutting equipment, in particular to a multi-needle-tube-disk simultaneous working type pulling and cutting equipment. Background Art

[0002] In the production process of a needle tube, the initial step is to take out the needle tube from the wound material. Subsequently, through a specific processing technology, the diameter of the needle tube will be gradually reduced. In order to improve the hardness and toughness of the needle tube, heat treatment processes of tempering and quenching will be carried out next. The processing flow is to first stretch the needle tube to reduce its diameter, and then enhance its physical properties through heat treatment. When the needle tube is taken out from the coil, a fixture is needed to fix it and move it to the cutting area for cutting.

The clamping device is provided with two gear disks on a frame table, and the gear disks are connected by a chain before. The clamping mechanism is fixed on the chain, and the needle tube coil is pulled out from the coil by the clamping mechanism. The needle tube is pulled by the clamping mechanism to the cutting device for cutting. This device can only perform pulling and cutting processing on one needle tube coil.

The cutting table is located at the cutting station and is fixed to the frame. One end of the cutting table protrudes upward to form a baffle.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1) The multi-needle tube tray simultaneous working type pulling and cutting device is simultaneously equipped with an upper pulling and cutting device and a lower pulling and cutting device. Both the upper pulling and cutting device and the lower pulling and cutting device include a frame body, a storage rotating frame, a clamping mechanism, a circulating driving mechanism and a cutting mechanism. The clamping mechanism, the circulating driving mechanism and the cutting mechanism in the upper pulling and cutting device are all stacked above the clamping mechanism, the circulating driving mechanism and the cutting mechanism in the lower pulling and cutting device, reducing the space occupied by the factory and saving the production cost.

[0018] 2) While the clamping mechanism, the circulating driving mechanism and the cutting mechanism in the upper pulling and cutting device are all stacked above the clamping mechanism, the circulating driving mechanism and the cutting mechanism in the lower pulling and cutting device, the circulating driving mechanism in the upper pulling and cutting device is directly opposite to the circulating driving mechanism in the lower pulling and cutting device, so that the sprockets of the two circulating driving mechanisms can be driven by one rotation driving device, thereby reducing the use of the driving device and further reducing the cost.

[0019] 3) Through the setting of the stop block in the cutting mechanism, it is realized that the cutting mechanism can move together with the clamping mechanism, and during the cutting process, the cutting mechanism can keep no relative movement relative to the clamping mechanism within a certain time, so as to ensure that the cutting mechanism can cut the position of the needle tube section beside the clamping mechanism. When cutting, the clamping of the clamping mechanism will not affect the cutting. When cutting the position of the needle tube section far from the clamping mechanism, the needle tube section will shake randomly, and the cutting operation cannot be completed when shaking.

[0020] Other advantages, objectives and features of the utility model will be partially reflected by the following description, and partially will also be understood by those skilled in the art through the research and practice of the utility model. Description of the Drawings

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners:

[0025] Such as Figure 1 And Figure 2As shown in the figure, the utility model provides a multi-needle tube tray simultaneous working type pulling and cutting device, including: an upper pulling and cutting device 1, a lower pulling and cutting device 2, and a rotary driving device 3; both the upper pulling and cutting device 1 and the lower pulling and cutting device 2 include: a frame body 11, a storage rotary frame 12, a clamping mechanism 13, a circulating driving mechanism 14, and a cutting mechanism 15. A circulating driving mechanism 14 is installed on the frame body 11. The output end of the circulating driving mechanism 14 is connected to at least three clamping mechanisms 13. A storage rotary frame 12 is installed beside the frame body 11, and the storage rotary frame 12 is used to place the needle tube tray. The position of the circulating driving mechanism 14 close to the rotary storage frame is the clamping station 16, one place in the circulating driving mechanism 14 is the cutting station 17, and another place in the circulating driving mechanism 14 is the discharging station 18. The cutting station 17 is located between the clamping station 16 and the discharging station 18. There is a distance between the clamping station 16 and the cutting station 17, a distance between the cutting station 17 and the discharging station 18, and a distance between the discharging station 18 and the clamping station 16. A cutting mechanism 15 is installed on the frame body 11, and the cutting mechanism 15 is located at the cutting station 17; the circulating driving mechanism 14 of the upper pulling and cutting device 1 is mounted above the circulating driving mechanism 14 of the lower pulling and cutting device 2 through the frame body 11; the circulating driving mechanisms 14 of both the upper pulling and cutting device 1 and the lower pulling and cutting device 2 are driven by the rotary driving device 3. After starting the rotary driving device 3, the chain 143 of the circulating driving mechanism 14 is driven to rotate. The clamping mechanism 13 on the chain 143 pulls the needle tube from the clamping station 16 to the discharging workpiece, and the needle tube is cut off by the cutting mechanism 15. The needle tube is ejected by the clamping mechanism 13 at the discharging station 18 and falls into the storage box 6.

[0026] The circulating driving mechanism 14 includes: a left sprocket 141, a right sprocket 142, and a chain 143. The chain 143 surrounds the left sprocket 141 and the right sprocket 142. The clamping mechanism 13 is installed on the chain 143. The left sprocket 141 of the upper pulling and cutting device 1 is vertically aligned with the left sprocket 141 of the lower pulling and cutting device 2, and the right sprocket 142 of the upper pulling and cutting device 1 is vertically aligned with the right sprocket 142 of the lower pulling and cutting device 2. The left sprocket 141 and the right sprocket 142 form a linkage mechanism through the chain 143.

[0027] The rotation drive device 3 includes: a drive motor 31, a left linkage shaft 32, a right linkage shaft 33, a first transmission gear 34, and a second transmission gear 35. The drive motor 31 is located below the right sprocket 142 of the upper traction cutting device 1. The output end of the drive motor 31 is connected to the first transmission gear 34. The second transmission gear 35 is fixed on the right linkage shaft 33. The first transmission gear 34 meshes with the second transmission gear 35. The left sprocket 141 of the upper traction cutting device 1 and the left sprocket 141 of the lower traction cutting device 2 are both connected to the left linkage shaft 32. The right sprocket 142 of the upper traction cutting device 1 and the right sprocket 142 of the lower traction cutting device 2 are both connected to the right linkage shaft 33. By driving the right sprocket 142 to rotate through the drive motor 31, and then driving the left sprocket 141 to rotate through the chain 143, the chain 143 drives the clamping mechanism 13 to move cyclically between the clamping station 16, the cutting station 17, and the discharging station 18.

[0028] The cutting mechanism 15 includes: a cutting table 151, a cutting seat 152, a stop block 153, a cutting knife 154, a cutting plate 155, and a sliding assembly 156. The cutting table 151 is located at the cutting station 17 and is fixed to the frame 11. One end of the cutting table 151 protrudes upward to form a baffle 1511. One end of the cutting seat 152 near the baffle 1511 protrudes upward to form a push plate. There is a certain distance between the baffle 1511 and the push plate, and the baffle 1511 and the push plate are connected by a spring 157. A first sliding assembly 156 is also provided on the cutting table 151, and the cutting seat 152 is slidably connected to the first sliding assembly 156. A telescopic driving device 158 is provided on the cutting seat 152, and the output end of the telescopic driving device 158 is connected to the cutting plate 155; a cutting knife 154 is provided on the cutting plate 155. A chute 1531 is opened on the push plate near the telescopic mechanism, and a stop block 153 is provided in the chute 1531. The stop block 153 is connected to the cutting plate 155. When the clamping mechanism 13 moves to the cutting station 17, the cutting plate 155 at the output end of the telescopic driving device 158 drives the stop block 153 to extend towards the chain 143 end. Since the extension length of the stop block 153 is greater than the extension length of the cutting knife 154, the stop block 153 has already contacted the clamping mechanism 13 before the cutting knife 154 contacts the syringe needle. At this time, as the clamping mechanism 13 moves, the clamping mechanism 13 drives the cutting knife 154 and the telescopic mechanism to move together through the stop block 153, and the spring 157 deforms; subsequently, the telescopic cylinder 159 continues to extend, so that the cutting knife 154 contacts the syringe needle to achieve cutting. During this process, the stop block 153 is in contact with the clamping mechanism 13 all the time, and the clamping mechanism 13 and the cutting knife 154 will not move in the same direction as the chain 143 transmission direction, ensuring that the cutting knife 154 cuts the syringe needle segment at a position beside the clamping mechanism 13 and ensuring the smooth progress of the cutting work; finally, the telescopic cylinder 159 retracts, so that the cutting knife 154 and the stop block 153 both move towards the cutting table 151, and the stop block 153 disengages from the clamping mechanism 13. The clamping mechanism 13 continues to move, and under the elastic force reduction of the spring 157, the cutting table 151, the stop block 153, and the cutting knife 154 are pulled back to the initial position, waiting for the next clamping mechanism 13 to arrive. At the same time, the previous clamping mechanism 13 opens to release the syringe needle, and the syringe needle will fall into the storage box 6 to achieve discharging. During the whole process, the syringe needle segment is continuously pulled out from the syringe needle disk, continuously cut into syringe needle segments, and discharged into the storage box 6

[0029] The telescopic driving device 158 is a cylinder 159. The stop block 153 is used to drive the telescopic driving device 158, the cutting seat 152, and the cutting knife 154 to move relative to the cutting table 151 together under the drive of the lifting seat of the clamping mechanism 13.

[0030] The sliding component 156 includes: a first limiting plate 1561, a second limiting plate 1562 and a sliding shaft 1563. The first limiting plate 1561 is located at one end of the cutting table 151 away from the baffle 1511, the second limiting plate 1562 is located at one end of the cutting seat 152 close to the baffle 1511. One end of the sliding shaft 1563 is connected to the first limiting plate 1561, the other end of the sliding shaft 1563 is connected to the second limiting plate 1562, and the sliding shaft 1563 passes through the cutting seat 152. When the block 153 extends to the chain 143, after the clamping mechanism 13 moves to the cutting station 17 and contacts the block 153, the clamping mechanism 13 will drive the cutting seat 152 to move towards the first limiting plate 1561. When the cutting seat 152 moves to the first limiting plate 1561 through the sliding shaft 1563, the cutting knife 154 cuts off the syringe needle. At the same time, the output end of the cylinder 159 retracts so that the block 153 is not pushed, and the spring 157 between the baffle 1511 and the push plate rebounds to pull the cutting seat 152 back to one end of the second limiting plate 1562.

[0031] A right guiding mechanism 4 is provided between the upper pulling and cutting device 1 and the storage rotating frame 12, and a left guiding mechanism 5 is provided between the lower pulling and cutting device 2 and the storage rotating frame 12. Both the left guiding mechanism 5 and the right guiding mechanism 4 include: a base 41 and a guiding component 42. The guiding component 42 is installed on the base 41, and the guiding component 42 allows the syringe needle to pass through. The right guiding mechanism 4 is higher than the left guiding mechanism 5. The right guiding mechanism 4 and the left guiding mechanism 5 respectively straighten the syringe needles in the storage rotating frame 12 of the upper pulling and cutting device 1 and the lower pulling and cutting device 2, keeping the syringe needles in a relatively straight state after being pulled out, ensuring that the syringe needles can be smoothly clamped by the clamping mechanisms 13 of the upper pulling and cutting device 1 and the lower pulling and cutting device 2.

[0032] A storage box 6 is provided between the discharging station 18 and the cutting station 17, and the storage box 6 is connected to the frame body 11. When the syringe needle is cut off, it will fall into the storage box 6 for subsequent use.
