Description

Technical Field

[0001] This utility model belongs to the field of medicine mixing machine technology, and in particular relates to a medicine mixing machine opening device. Background Technology

[0002] Currently, mixing machines typically use their mixing tanks to mix medicinal powders. After the powder is loaded and before mixing, the sealing caps on the mixing tank openings need to be manually closed and opened respectively for convenient mixing and unloading. However, because the mixing tank contains medicinal powder, the tank opening needs to be positioned high up when the sealing cap is closed, which is inconvenient for manual operation and results in low efficiency. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a cap-opening device for a mixing machine, which can improve the cap-opening efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A mixing machine opening device includes a sealing cover and a linear drive mechanism. Both sides of the sealing cover are laterally slidably connected with plug-in parts for insertion into the mixing tank. The two plug-in parts are provided with a first snap-fit ​​part at one end that is close to each other.

[0006] The linear drive mechanism is fixedly connected to the mixing machine in the longitudinal direction. The output end of the linear drive mechanism is fixedly connected to a parallel gripper with lateral displacement. The lower ends of the two grippers of the parallel gripper are provided with a second clamping part for clamping with the first clamping part.

[0007] Both sides of the sealing cover are provided with sliding grooves for sliding connection with the first snap-fit ​​part and the second snap-fit ​​part.

[0008] The beneficial effects of adopting the above technical solution are as follows: the linear drive mechanism and the parallel gripper can drive the two second locking parts to move longitudinally and laterally symmetrically, respectively. That is, the two second locking parts can engage with the two first locking parts by moving longitudinally and laterally, and then pull the plug-in from the mixing tank by moving laterally symmetrically to release the connection between the sealing cap and the mixing tank. When the two second locking parts move laterally to the end of the sliding groove, they can clamp the sealing cap, which makes it easy to remove the sealing cap from the mixing tank. In reverse operation, the sealing cap can be placed on the mixing tank, which is conducive to realizing automatic opening and closing of the cap, thereby reducing manual operation and improving the opening efficiency.

[0009] In one embodiment, the mixing machine opening device includes a support frame fixedly connected to the mixing machine, and a linear drive mechanism is fixedly connected to the support frame.

[0010] The beneficial effects of adopting the above technical solution are: the support frame provides mounting space for the linear drive mechanism, thereby avoiding interference with the installation space.

[0011] In one embodiment, a first mounting plate is detachably connected to the support frame, a linear drive mechanism is fixedly connected to the first mounting plate, a second mounting plate is fixedly connected to the output end of the linear drive mechanism, a parallel gripper is fixedly connected to the second mounting plate, and a plurality of guide rods are longitudinally fixedly connected to the second mounting plate, all of which are slidably connected to the first mounting plate.

[0012] The beneficial effects of adopting the above technical solution are as follows: several guide rods provide guidance for the movement of the parallel gripper, so that the linear drive mechanism can stably output longitudinal displacement and the parallel gripper can stably move longitudinally.

[0013] In one embodiment, a floating joint is provided on the second mounting plate, and the output end of the linear drive mechanism is connected to the floating joint.

[0014] The beneficial effect of adopting the above technical solution is that the output end of the linear drive mechanism is connected to the second mounting plate through a floating joint.

[0015] In one embodiment, a plurality of linear bearings are provided on the first mounting plate, and a plurality of guide rods are respectively inserted into the plurality of linear bearings.

[0016] The beneficial effect of adopting the above technical solution is that this setting makes the guide rod slide more smoothly.

[0017] In one embodiment, the mixing machine opening device includes locking seats fixedly connected to both sides of the mixing tank opening, support seats are provided on both sides of the sealing cover, and one end of the plug-in passes through the support seat laterally and is plugged into the locking seat.

[0018] The beneficial effects of adopting the above technical solution are as follows: one end of the connector passes horizontally through the support base and is inserted into the locking base to lock the sealing cover at the mouth of the mixing tank; after the connector is pulled out from the locking base, the connection between the sealing cover and the mixing tank can be released.

[0019] In one embodiment, the connector is a pin, the support base has a first hole for the pin to pass through, and the locking base has a second hole for the pin to be inserted.

[0020] In one embodiment, the lower ends of the two jaws of the parallel gripper are fixedly connected to a pawl, and a second locking part is provided at the lower part of the pawl. The widths of the first locking part and the second locking part are both matched with the width of the sliding groove.

[0021] The beneficial effects of adopting the above technical solution are: the sliding groove limits the first and second locking parts, and at the same time provides sliding support for the first and second locking parts.

[0022] In one embodiment, the first latching part includes a block body disposed at one end of the plug-in, and a protrusion is provided on the upper outer side of the block body. The second latching part includes a square groove body disposed at the lower part of the pawl, and a groove matching the protrusion is provided on the upper outer side of the square groove body. The groove length and groove depth of the square groove body are matched with the length and height of the block body, respectively. The groove width of the square groove body is greater than the sum of the widths of the block body and the protrusion.

[0023] The beneficial effects of adopting the above technical solution are as follows: Since the width of the square groove is greater than the sum of the widths of the block and the protrusion, the two claws can move longitudinally so that the protrusion and the block go deep into the square groove; when both claws move laterally inward, the protrusion can be engaged in the groove so as to achieve the engagement of the first engagement part and the second engagement part.

[0024] In one embodiment, the outer side of the square groove is provided with a through groove for the insertion member to pass through; wherein, when the insertion member contacts the bottom of the through groove, the square block contacts the bottom of the square groove.

[0025] The beneficial effect of adopting the above technical solution is that this setting avoids interference between the plug and the cube entering the square groove.

[0026] The beneficial effects of this utility model are as follows:

[0027] The linear drive mechanism and parallel grippers can drive the two second locking parts to move longitudinally and laterally symmetrically, respectively. That is, the two second locking parts can engage with the two first locking parts by moving longitudinally and laterally, respectively. Then, by moving laterally symmetrically, the plug can be pulled out from the mixing tank to release the connection between the sealing cap and the mixing tank. When the two second locking parts move laterally to the end of the sliding groove, they can clamp the sealing cap, making it easy to remove the sealing cap from the mixing tank. In reverse, the sealing cap can be placed on the mixing tank, which facilitates automatic opening and closing of the cap, thereby reducing manual operation and improving the opening efficiency.

Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] This utility model provides a device for opening the lid of a mixing machine, such as... Figure 1-5 As shown, it includes a sealing cover 3 and a linear drive mechanism 4. Both sides of the sealing cover 3 are laterally slidably connected with plug-in parts 15 for insertion into the mixing tank 2. The two plug-in parts 15 are provided with a first snap-fit ​​part at one end that is close to each other.

[0043] The linear drive mechanism 4 is longitudinally fixedly connected to the mixing machine 1. The output end of the linear drive mechanism 4 is fixedly connected to the parallel gripper 11 with lateral displacement. The lower ends of the two grippers of the parallel gripper 11 are provided with a second clamping part for clamping with the first clamping part.

[0044] Both sides of the sealing cover 3 are provided with sliding grooves 301 for sliding connection with the first snap-fit ​​part and the second snap-fit ​​part.

[0045] It is understandable that the linear drive mechanism 4 and the parallel gripper 11 can drive the two second locking parts to move longitudinally and laterally symmetrically, respectively. That is, the two second locking parts can engage with the two first locking parts by moving longitudinally and laterally, respectively. Then, by moving laterally symmetrically, the plug 15 can be pulled out from the mixing tank 2 to release the connection between the sealing cap 3 and the mixing tank 2. When the two second locking parts move laterally to the end of the sliding groove 301, they can clamp the sealing cap 3, making it easy to remove the sealing cap 3 from the mixing tank 2. In reverse, the sealing cap 3 can be placed on the mixing tank 2, which is conducive to automatic opening and closing of the cap, thereby reducing manual operation and improving the opening efficiency. At the same time, this mixing machine opening device does not require personnel to go to high places to operate. For special powders such as explosives, the standardization of the mixing machine opening device is higher, which can reduce safety risks.

[0046] It should be noted that the parallel gripper 11 can drive the two second locking parts to move laterally to the ends of the two sliding grooves 301 at the same time, so as to clamp the sealing cover 3 at the same time; and the sealing cover 3 is connected to the mixing tank 2 through two plug-in parts 15, which can effectively prevent single failure.

[0047] It should also be noted that the linear drive mechanism 4 can be a cylinder, and the parallel gripper 11 can be a pneumatic gripper; in addition, the lower part of the sealing disc is set into a conical shape to form an effective guide with the conical part of the mouth of the mixing tank 2 to ensure the alignment of the axis; at the same time, a sealing ring is installed on the outer periphery of the sealing disc to effectively seal the mixing tank 2.

[0048] In one embodiment, such as Figure 2 As shown, the mixing machine opening device includes a support frame 5 fixedly connected to the mixing machine 1, and a linear drive mechanism 4 fixedly connected to the support frame 5.

[0049] Understandably, the support frame 5 provides mounting space for the linear drive mechanism 4 to avoid interference with the installation space.

[0050] In one embodiment, a first mounting plate 6 is detachably connected to the support frame 5, a linear drive mechanism 4 is fixedly connected to the first mounting plate 6, a second mounting plate 10 is fixedly connected to the output end of the linear drive mechanism 4, a parallel gripper 11 is fixedly connected to the second mounting plate 10, and four guide rods 8 are longitudinally fixedly connected to the second mounting plate 10, all of which are slidably connected to the first mounting plate 6.

[0051] Understandably, the four guide rods 8 provide guidance for the movement of the parallel gripper 11, so that the linear drive mechanism 4 can stably output longitudinal displacement and the parallel gripper 11 can stably move longitudinally.

[0052] In one embodiment, a floating joint 9 is provided on the second mounting plate 10, and the output end of the linear drive mechanism 4 is connected to the floating joint 9.

[0053] In one embodiment, the first mounting plate 6 is provided with four linear bearings 7, and four guide rods 8 are respectively inserted into the four linear bearings 7 to make the guide rods 8 slide more smoothly.

[0054] In one embodiment, the mixing machine opening device includes locking seats 13 fixedly connected to both sides of the opening of the mixing tank 2, and support seats 14 are provided on both sides of the sealing cover 3. One end of the plug 15 passes through the support seat 14 laterally and is plugged into the locking seat 13.

[0055] Understandably, one end of the connector 15 passes laterally through the support base 14 and is inserted into the locking base 13 to lock the sealing cap 3 at the mouth of the mixing tank 2; after the connector 15 is pulled out of the locking base 13, the connection between the sealing cap 3 and the mixing tank 2 can be released.

[0056] In one embodiment, the connector 15 is a pin, the support base 14 is provided with a first hole for the pin to pass through, and the locking base 13 is provided with a second hole for the pin to be inserted.

[0057] In one embodiment, the lower ends of the two grippers of the parallel gripper 11 are fixedly connected to the claw 12, and the lower part of the claw 12 is provided with a second locking part. The width of the first locking part and the width of the second locking part are both matched with the width of the sliding groove 301. The sealing cover 3 is provided with spring positioning pins on both sides of the sliding groove 301.

[0058] Understandably, the sliding groove 301 limits the first and second locking parts, while providing sliding support for the first and second locking parts.

[0059] In one embodiment, such as Figure 5-7 As shown, the first latching part includes a block 1501 disposed at one end of the plug-in 15, and a protrusion 1502 disposed on the upper outer side of the block 1501. The second latching part includes a square groove 1201 disposed at the lower part of the pawl 12, and a groove 1202 that matches the protrusion 1502 is disposed on the upper outer side of the square groove 1201. The groove length and groove depth of the square groove 1201 match the length and height of the block 1501, respectively. The groove width of the square groove 1201 is greater than the sum of the widths of the block 1501 and the protrusion 1502.

[0060] It is understandable that, since the width of the groove 1201 is greater than the sum of the widths of the block 1501 and the protrusion 1502, the two claws 12 can move longitudinally so that the protrusion 1502, together with the block 1501, penetrates into the groove 1201; when both claws 12 move laterally inward, the protrusion 1502 can be engaged in the groove 1202 to achieve engagement between the first engaging part and the second engaging part.

[0061] In one embodiment, such as Figure 8 As shown, the outer side of the square groove 1201 is provided with a through groove 1203 for the insertion member 15 to pass through; wherein, when the insertion member 15 contacts the bottom of the through groove 1203, the square block 1501 contacts the bottom of the square groove 1201, so as to avoid the insertion member 15 interfering with the square block 1501 entering the square groove 1201.

[0062] The opening process of this utility model is as follows:

[0063] When the mixing tank 2 is rotated to the open position, the output end of the linear drive mechanism 4 moves longitudinally downward to the limit position so that the block 1501 contacts the bottom of the square trough 1201.

[0064] Parallel gripper 11 retracts inward so that protrusion 1502 is engaged in slot, thereby engaging the two claws 12 with the two connectors 15.

[0065] The parallel gripper 11 continues to retract inward to pull the connector 15 off the mixing container 2 and to clamp the sealing cap 3 with the claw 12.

[0066] The output end of the linear drive mechanism 4 moves longitudinally upward to disengage the sealing cap 3 from the mixing tank 2.

[0067] The closing process of this utility model is as follows:

[0068] When the mixing tank 2 is rotated to the closed position, the output end of the linear drive mechanism 4 moves vertically downward so that the sealing cap 3 covers the opening of the mixing tank 2.

[0069] The two jaws of the parallel jaw 11 move outward to insert the connector 15 into the mixing tank 2, thereby connecting the sealing cap 3 to the mixing tank 2 and causing the claw 12 to no longer clamp the sealing cap 3.

[0070] The two jaws of the parallel gripper 11 continue to move outward so that the protrusion 1502 exits the slot and enters the square groove 1201;

[0071] The output end of the linear drive mechanism 4 moves longitudinally upward so that components such as the pawl 12 move away from the mixing tank 2, thereby preventing the pawl 12 and other components from affecting the rotation of the mixing tank 2.
