Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a long-stroke dual-head dispensing device. Background Technology

[0002] Currently, there are many dual-head dispensing devices on the market. A dual-head dispensing device refers to a dispensing device with two dispensing heads, which allows the dispensing device to perform dual-head dispensing operations on the product to be dispensed at the same time, thereby improving dispensing efficiency.

[0003] To improve the versatility of dual-head dispensing devices, some dual-head dispensing devices will choose to add a spacing adjustment component to adjust the distance between the two dispensing heads. However, the existing spacing adjustment components have problems such as complex structure, inability of non-fully independent dual-head dispensing devices to achieve large-stroke dual-head dispensing operations, and high manufacturing costs. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the existing spacing adjustment components have complex structures, the non-fully independent dual-head dispensing device cannot achieve large-stroke dual-head dispensing operations, and the manufacturing cost is relatively high. Therefore, a large-stroke dual-head dispensing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A long-stroke dual-head dispensing device includes a platform and a base plate. The platform is fixedly connected to the upper surface of the base plate, and support feet are provided at the four corners of the lower surface of the base plate.

[0007] The platform is equipped with a dual-dispensing assembly, which includes a first slide rail, a Y-axis drive assembly, a second slide rail, an X-axis drive assembly, a third slide rail, and a Z-axis drive assembly. The two first slide rails are respectively fixedly connected to both ends of the upper surface of the platform. The two Y-axis drive assemblies are respectively slidably connected to the first slide rails. The two second slide rails are respectively fixedly connected to the upper end face of the Y-axis drive assembly. The two X-axis drive assemblies are respectively slidably connected to the second slide rails. The two third slide rails are respectively fixedly connected to the side wall of the X-axis drive assembly. The two Z-axis drive assemblies are respectively slidably connected to the third slide rails.

[0008] Preferably, the dual dispensing assembly further includes a first dispensing head and a second dispensing head, which are respectively fixedly connected to the side wall of the Z-axis drive assembly.

[0009] Preferably, a control box is fixedly connected to the side wall of each of the Y-axis drive assembly, X-axis drive assembly, and Z-axis drive assembly. A storage tank is fixedly connected to the top wall of the control box. An outer tube is fixedly connected to the lower end face of the storage tank. An inner tube is rotatably connected to the inner side wall of the outer tube.

[0010] Preferably, a sliding groove is provided on the bottom wall of the control box, and an inverted T-shaped friction block is slidably connected in the sliding groove. Multiple friction blocks are slidably connected to the first slide rail, the second slide rail, and the third slide rail, respectively. A toothed ring is fixedly connected to the outer surface of the inner tube, and a rack plate is fixedly connected to the upper end face of the friction block. The rack plate is meshed with the toothed ring, and a return spring is fixedly connected between the friction block and the inner side wall of the sliding groove.

[0011] Preferably, a sponge block is fixedly connected to the lower end face of the control box, and multiple sponge blocks are slidably connected to the first slide rail, the second slide rail, and the third slide rail respectively. A conduit is fixedly connected between the sponge block and the inner tube.

[0012] Preferably, a plurality of first sector blocks are installed in a circular array on the inner wall of the inner tube, and a plurality of second sector blocks are installed in a circular array on the inner wall of the outer tube, wherein the first sector blocks and the second sector blocks are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By using two sets of slide rails and a multi-axis drive assembly that operates simultaneously, two dispensing heads are driven to work at the same time, thereby improving dispensing performance and efficiency, reducing the idle time of the dispensing mechanism caused by large stroke idling, and effectively reducing the idle time of large stroke dispensing, thus improving production efficiency.

[0015] 2. The friction block drives the rack plate to move, which in turn drives the inner tube to rotate. This causes the first sector block and the second sector block to intersect and form a gap, allowing the lubricating fluid in the storage tank to automatically flow into the sponge block according to the lubrication level of the track. This lubricates the track, avoiding the rapid wear caused by the dual components. It also eliminates the need to periodically stop the machine to add lubricating fluid to the track and clean it, thus improving production efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0026] Reference Figures 1-7 The long-stroke double-head dispensing device includes a platform 1 and a base plate 2. The platform 1 is fixedly connected to the upper surface of the base plate 2, and support feet are provided at the four corners of the lower surface of the base plate 2.

[0027] The platform 1 is equipped with a dual-dispensing assembly, which includes a first slide rail 3, a Y-axis drive assembly 4, a second slide rail 5, an X-axis drive assembly 6, a third slide rail 7, and a Z-axis drive assembly 8. Two first slide rails 3 are fixedly connected to both ends of the upper surface of the platform 1. Two Y-axis drive assemblies 4 are slidably connected to the first slide rails 3. Two second slide rails 5 are fixedly connected to the upper end face of the Y-axis drive assembly 4. Two X-axis drive assemblies 6 are slidably connected to the second slide rails 5. Two third slide rails 7 are fixedly connected to the platform. On the side wall of the X-axis drive assembly 6, two Z-axis drive assemblies 8 are slidably connected to the third slide rail 7. The dual dispensing assembly also includes a first dispensing head 9 and a second dispensing head 10, which are fixedly connected to the side wall of the Z-axis drive assembly 8. The two sets of slide rails and the multi-axis drive assembly that operate simultaneously drive the two dispensing heads to operate at the same time, thereby improving dispensing performance and efficiency, reducing the idle time of the dispensing mechanism caused by large stroke idling, and effectively reducing the idle time of large stroke dispensing, thus improving production efficiency.

[0028] A control box 11 is fixedly connected to the side wall of the Y-axis drive assembly 4, the X-axis drive assembly 6, and the Z-axis drive assembly 8. A storage tank 12 is fixedly connected to the top wall of the control box 11. The storage tank 12 stores lubricating fluid. An outer tube 13 is fixedly connected to the lower end face of the storage tank 12. An inner tube 14 is rotatably connected to the inner side wall of the outer tube 13.

[0029] A sliding groove is provided on the bottom wall of the control box 11. An inverted T-shaped friction block 15 is slidably connected in the sliding groove. Multiple friction blocks 15 are slidably connected to the first slide rail 3, the second slide rail 5, and the third slide rail 7, respectively. A toothed ring 16 is fixedly connected to the outer surface of the inner tube 14. A rack plate 17 is fixedly connected to the upper end face of the friction block 15. The rack plate 17 is meshed with the toothed ring 16. A return spring 18 is fixedly connected between the friction block 15 and the inner side wall of the sliding groove.

[0030] A sponge block 19 is fixedly connected to the lower end face of the control box 11. Multiple sponge blocks 19 are slidably connected to the first slide rail 3, the second slide rail 5, and the third slide rail 7 respectively. A conduit 20 is fixedly connected between the sponge block 19 and the inner tube 14.

[0031] Multiple first sector blocks 21 are installed in a ring array on the inner wall of the inner tube 14, and multiple second sector blocks 22 are installed in a ring array on the inner wall of the outer tube 13. The first sector blocks 21 and the second sector blocks 22 are connected in a sealed sliding connection. The multiple first sector blocks 21 and the multiple second sector blocks 22 are arranged alternately to form a seal on the storage tank 12 when the friction block 15 is not under force.

[0032] In this invention, when dispensing is required, two sets of slide rails and a multi-axis drive assembly that operate simultaneously drive two dispensing heads to operate at the same time, thereby improving dispensing performance and efficiency, reducing the idle time of the dispensing mechanism caused by large stroke idling, and effectively reducing the idle time of large stroke dispensing, thus improving production efficiency.

[0033] When the various drive components drive the control box 11 to slide on the various slide rails, the control box 11 drives the friction block 15 to move on the slide rails. When the slide rails are relatively smooth, the friction between the friction block 15 and the slide rails is small, and the friction block 15 does not move. However, as the lubrication on the slide rails fails rapidly due to the use of the two systems, and as dust continuously falls onto the slide rails over time, the friction on the slide rail surface increases, causing the drive components to operate less smoothly. At this point, the friction block 15 moves under the action of friction, in the opposite direction to the movement of the control box 11, thereby driving the rack plate 17 to move to the left or right, compressing the return spring 18 on that side, and stretching the return spring 18 on the other side. The rack plate 17 drives the inner tube 14 to rotate through the gear ring 16, thereby causing the multiple first sector blocks 21 in the inner tube 14 to interact with the multiple first sector blocks 21 in the outer tube 13. The second sector block 22 is misaligned, no longer sealing the storage tank 12. The lubricant in the storage tank 12 flows through the inner tube 14 and the outer tube 13, and then through the conduit 20 into the sponge block 19. The sponge block 19 evenly coats the lubricant onto the slide rail, lubricating it. When the rail becomes smooth, the friction between the rail and the friction block 15 disappears. The friction is insufficient to drive the friction block 15. Under the elastic force of the return springs 18 on both sides, the friction block 15 drives the rack plate 17 to reset. The first sector block 21 and the second sector block 22 close together to reseal the storage tank 12. This allows the lubricant in the storage tank 12 to automatically flow into the sponge block 19 according to the lubrication level of the rail, avoiding rapid wear caused by the dual components. It eliminates the need for periodic shutdowns to add lubricant to the rail and clean the rail, thus improving production efficiency.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
