Description

Technical Field

[0001] The utility model relates to the technical field related to agricultural machinery, in particular to a white film positioning and bonding device for an agricultural machinery engine casting. Background Art

[0002] In the field of modern industrial manufacturing, casting-grade film is widely used in surface protection, decoration and value-added treatment of various products. This technology can provide products with excellent wear resistance, corrosion resistance and aesthetics, thereby extending the service life of the products, increasing the added value of the products, and bringing higher texture and quality to the product surface. As a high-end technology, casting-grade film can effectively prevent damage to the products caused by external factors such as wear and corrosion by providing a protective film on the surface of the product. At the same time, through its aesthetics and durability, it can enhance the overall value and market competitiveness of the product. This treatment method is not only suitable for various types of products, but also has a wide range of applications in many industries, including but not limited to machinery, electronics, household goods, etc., providing a guarantee for the long-term use and beauty of the products.

[0003] The existing white film positioning and bonding device for agricultural machinery engine castings usually sticks the white film on the surface of the casting during pasting, and then uses a hot air gun to blow and bake it. However, when the white film is pasted to the casting, the adhesion between the surface of the casting and the white film is relatively high, resulting in the casting and the white film being tightly adhered together before the hot air gun is used to blow and bake it. As a result, the white film cannot be slightly moved when the hot air gun is blown and baked, and bubbles may appear between the white film and the casting. The overall compliance is not high, resulting in a low pasting effect and poor aesthetics. Utility Model Content

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0027] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0028] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0029] See also Figure 1 to Figure 7 In an embodiment of the utility model, a white film positioning and bonding device for an agricultural machinery engine casting includes a workbench 1, a support frame 2, a plunger pump 17, a piston 19, a reciprocating drive member and an elastic extrusion structure.

[0030] For details, please refer to Figure 1 , Figure 3 , Figure 4 ,include;

[0031] A workbench 1 and a support frame 2 fixedly mounted on the workbench 1, wherein a reciprocating driving member is mounted on the workbench 1, and the reciprocating driving member can drive a receiving plate 8 slidably mounted on the workbench 1 to reciprocate;

[0032] It also includes a plunger pump 17 fixedly mounted on the support frame 2, wherein a pumping assembly is arranged in the plunger pump 17, and the pumping assembly includes a piston 19 slidably arranged in the plunger pump 17 and an elastic extrusion structure connected to the piston 19. When the receiving plate 8 moves, the elastic extrusion structure is controlled to deform through a one-way transmission member to squeeze the piston 19 to move relative to the plunger pump 17.

[0033] Preferably, a connecting head is provided at the center of the receiving plate 8, and the connecting head is detachably connected to the casting.

[0034] In detail, in this embodiment, the white film positioning and bonding device for the agricultural machinery engine casting described in the utility model is adopted. When in use, the reciprocating drive member is started to drive the receiving plate 8 to move relative to the workbench 1. When the receiving plate 8 moves, the casting thereon is driven to move synchronously. At the same time, the elastic extrusion structure is controlled to deform through the one-way transmission member. The elastic extrusion structure generates an extrusion force on the piston 19. The piston 19 slides relatively in the plunger pump 17. The pressure in the plunger pump 17 increases, so that the plunger pump 17 sprays the casting. A layer of water mist on the surface of the casting can temporarily reduce the viscosity of the casting and will not affect the viscosity after drying, so as to increase the fit between the white film and the casting during subsequent pasting.

[0035] See also Figure 2 The reciprocating drive member includes two pulleys 5 rotatably mounted on the workbench 1, one of which is driven to rotate by a motor 7 fixedly mounted at the bottom of the workbench 1;

[0036] The two pulleys 5 are connected by a conveyor belt 6 , and a protruding column 601 is provided on the conveyor belt 6 .

[0037] The receiving plate 8 is formed with a sliding groove 801 which is slidably matched with the protruding column 601 .

[0038] To elaborate, after the casting is installed on the receiving plate 8, the motor 7 is started to work. When the motor 7 is working, it drives the output shaft to rotate. When the output shaft rotates, it drives one of the pulleys 5 to rotate at a reduced speed through the reducer arranged at the bottom of the workbench 1. Under the action of the conveyor belt 6, the rotation requirements of the two pulleys 5 are met, and when the conveyor belt 6 rotates, the boss 601 thereon is driven to rotate synchronously, wherein the movement trajectory of the boss 601 is elliptical, and the boss 601 squeezes the slide groove 801 when it moves, and the receiving plate 8 slides on the workbench 1 in a directional manner under the action of the guide rod 9, so that when the boss 601 moves, the receiving plate 8 is squeezed and moves relative to the workbench 1, so as to meet the need for the casting to move on the workbench 1.

[0039] See also Figure 4 and Figure 5 The elastic extrusion structure includes a sleeve 20 and a connecting shaft 21. The sleeve 20 is arranged along the axial direction of the piston 19 and is fixedly connected to the piston 19. One end of the connecting shaft 21 is fixedly installed on the support frame 2, and the other end is inserted into the sleeve 20 and is slidably connected to the sleeve 20.

[0040] The spring 22 is also included. The spring 22 is disposed in the sleeve 20 , one end of the spring 22 abuts against the inner top of the sleeve 20 , and the other end abuts against the connecting shaft 21 .

[0041] It should be noted that the plunger pump 17 is provided with a water inlet and a water outlet, and both the water outlet and the water inlet are provided with a one-way valve. When the pressure in the plunger pump 17 increases, the liquid squeezes the one-way valve on the water outlet, causing the liquid to flow out from the water outlet. When the pressure in the plunger pump 17 decreases, the liquid squeezes the one-way valve on the water inlet, absorbing the external liquid to flow in from the water inlet.

[0042] Furthermore, when the receiving plate 8 moves, the movement of the sleeve 20 is controlled by the one-way transmission member. At this time, the sleeve 20 drives the piston 19 to move downward in the plunger pump 17, and the volume in the plunger pump 17 is reduced and the pressure is increased, so that the liquid in the plunger pump 17 flows out to the outside to realize the spraying work on the surface of the casting. At the same time, the sleeve 20 slides relative to the connecting shaft 21 when it moves. At this time, the spring 22 is compressed to reserve elastic potential energy. When the receiving plate 8 moves over the lower end of the plunger pump 17, the one-way transmission member loses the driving force and cannot transmit. Under the action of the spring 22, the sleeve 20 and the piston 19 are squeezed to reset. At this time, the pressure in the plunger pump 17 is reduced, and the external liquid is absorbed into the plunger pump 17 to prepare for the next spraying work.

[0043] See also Figure 3 The one-way transmission member includes a first transmission shaft 12 and a second transmission shaft 13 rotatably mounted on the workbench 1. The first transmission shaft 12 and the second transmission shaft 13 are perpendicular to each other and are rotatably connected through a bevel gear set 15. A ratchet 11 is fixedly connected to the first transmission shaft 12, and the ratchet 11 is meshed with a ratchet plate 10 fixedly mounted on the receiving plate 8. A gear 14 is fixedly provided on the second transmission shaft 13, and the gear 14 is meshed with a toothed plate 16 fixedly mounted on the sleeve 20.

[0044] It should be noted that: a plurality of linearly distributed grooves are formed on the ratchet plate 10, a ratchet bar is rotatably installed in the groove, and a torsion spring is arranged between the ratchet bar and the groove, when the receiving plate 8 moves toward the side of the heating device 4, the ratchet bar can engage with the ratchet wheel 11 and rotate, and when the receiving plate 8 is reset, the ratchet bar contacts the ratchet wheel 11 and gives way under the action of the torsion spring, and at this time, the movement of the receiving plate 8 has no effect on the ratchet wheel 11.

[0045] When the above-mentioned receiving plate 8 moves (moves toward the side of the heating device 4), the ratchet plate 10 thereon is driven to move synchronously, and the ratchet bar meshes with the ratchet wheel 11 when in contact, so that the ratchet wheel 11 rotates, and when the ratchet wheel 11 rotates, it drives the first transmission shaft 12 to follow the rotation, and under the action of the bevel gear set 15, the second transmission shaft 13 rotates, and when the second transmission shaft 13 rotates, it drives the gear 14 to rotate synchronously, and when the gear 14 rotates, because the gear 14 is in a meshing state with the tooth plate 16, the requirement of moving the tooth plate 16 is realized, thereby driving the sleeve 20 to move synchronously.

[0046] Among them, when the ratchet plate 10 is completely disengaged from the ratchet wheel 11, the tooth plate 16 loses the driving force. At this time, the sleeve 20 is reset under the action of the spring 22. During the resetting process, the sleeve 20 drives the tooth plate 16 to rotate synchronously, so as to drive the first transmission shaft 12 and the second transmission shaft 13 to rotate in the opposite direction. However, the rotation of the first transmission shaft 12 at this time has no effect on the ratchet plate 10 and the receiving plate 8.

[0047] See also Figure 4 The bottom of the plunger pump 17 is fixedly connected with a nozzle 18 and is communicated with the inner side of the nozzle 18. In order to ensure the stability of the nozzle 18 in performing the spraying work, the nozzle 18 is fixedly connected to the support frame 2 through a support plate, wherein an atomizing device is arranged in the nozzle 18 to convert the liquid discharged from the plunger pump 17 into a state of mist droplets and then spray the casting. It is necessary to ensure that the spraying amount each time is not too much to prevent excessive moisture on the surface of the casting from affecting the subsequent film pasting work.

[0048] See also Figure 1 and Figure 2 The agricultural machinery engine casting white film positioning and bonding device also includes an automatic film pasting device 3 and a heating device 4, and the automatic film pasting device 3 and the heating device 4 are arranged along the moving direction of the receiving plate 8.

[0049] The above-mentioned receiving plate 8 drives the casting to move to the automatic film pasting device 3, and the automatic film pasting device 3 is started. At this time, the receiving plate 8 is in a moving state but the moving speed is slow. The automatic film pasting device 3 completes the film pasting work on the casting while it is moving, but the surface of the casting is uneven, and the white film and the casting are not completely pasted at this time. The specific automatic film pasting device 3 belongs to the prior art, and this utility model will not provide any unnecessary explanation.

[0050] It should be noted that a hood 23 is provided on the side of the heating device 4, the hood 23 is connected to the heating device 4, and a wind turbine 24 is installed in the hood 23, and a driving member is connected to the wind turbine 24, which can be a motor. When the casting moves to the bottom of the wind turbine 24, the receiving plate 8 stops moving and the motor is started. When the wind turbine 24 is working, the hot air in the heating device 4 is blown onto the casting, so that the white film attached to the casting can better fit the concave and convex structure of the casting surface. After the entire film pasting is completed, the receiving plate 8 drives the casting to reset and flip over, and the film pasting work on the other side of the casting begins.

[0051] In general, the water spraying work is performed before the casting is filmed, mainly to reduce the layer of water mist on the surface of the casting, which can temporarily reduce the viscosity of the casting, and ensure that when the casting moves to the lower end of the wind turbine 24 after the automatic film-laminating device 3 completes the film-laminating work, hot air is blown onto the casting, and the white film can move slightly to better fit the concave and convex structure of the casting surface.

[0052] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
