Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, and more specifically, to an adhesive pressure plate. Furthermore, this utility model also relates to an adhesive supply device including the aforementioned adhesive pressure plate. Background Technology

[0002] Pressure plate type glue dispensing devices have become the mainstream glue dispensing solution for high-precision dispensing equipment because they can overcome the differences in rheological properties of glue through constant pressure output and avoid the shear heating and deterioration problems of traditional screw pumps. This device usually consists of a glue cylinder, a hydraulically driven plunger pressure plate, and glue delivery pipeline. Its technical advantage lies in using the pressure plate to apply uniform axial pressure to the glue in the glue cylinder.

[0003] Currently, when using a pressure plate connected to a plunger pump for glue supply, when the bottom of the pressure plate touches the bottom of the glue container, the residual glue in the pressure plate can no longer be pumped out by the plunger pump. However, a large amount of glue remains in the inner cavity connecting the pressure plate and the plunger pump. The larger the cavity, the more residual glue remains. During the glue container replacement process, most of the residual glue flows back into the old glue container, resulting in a significant waste. A small portion also falls onto the base plate of the glue supply equipment during container replacement, requiring manual cleaning. The glue is extremely difficult to clean, increasing production difficulty.

[0004] In conclusion, how to reduce glue waste is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a glue pressing plate that, through an anti-drip structure, can greatly reduce glue waste and effectively improve glue utilization.

[0006] Another objective of this invention is to provide a glue supply device including the aforementioned glue pressure plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A glue pressing plate, comprising:

[0009] The pressure plate body includes a glue passage that runs through the pressure plate body, and the two ends of the glue passage are a glue inlet and a glue outlet, respectively.

[0010] An anti-drip assembly includes a floating plate installed on the pressure plate body. The floating plate and the pressure plate body are movable relative to each other so that the floating plate controls the opening and closing of the glue inlet. When the floating plate is only subjected to gravity, the floating plate is in a closed glue inlet state.

[0011] Furthermore, the anti-drip component of this utility model also includes:

[0012] A fixed plate is fixedly installed on the glue inlet. The fixed plate is provided with at least one glue passage. The floating plate is located on the side of the fixed plate close to the pressure plate body. When the floating plate is only subjected to gravity, the floating plate contacts the fixed plate to close the glue passage.

[0013] Furthermore, in this invention, the fixing plate has a disc-shaped structure, there are three glue outlets evenly distributed along the axis of the fixing plate, and the floating plate is an annular structure coaxial with the fixing plate.

[0014] Furthermore, the present invention provides an installation groove at the glue inlet, and the fixing plate is located in the installation groove so that the fixing plate and the same side of the pressure plate body away from the glue outlet are located on the same plane.

[0015] Furthermore, the fixing plate is provided with at least one guide post, and the pressure plate body is provided with a fixing groove for fixing the guide post.

[0016] Furthermore, the anti-drip component of this utility model also includes:

[0017] A reset component is used to control the floating plate to move in the direction of closing the glue inlet.

[0021] An adhesive supply device includes an adhesive pressure plate as described in any of the above claims.

[0022] The glue press plate provided by this utility model, in use, has a floating plate 202 installed on the press plate body 1, allowing the floating plate 202 and the press plate body 1 to move relative to each other, so that the floating plate 202 controls the opening and closing of the glue inlet 103. The press plate body 1 is placed in the glue bucket, and the glue outlet 102 of the press plate body 1 is connected to a plunger pump. The plunger pump is used to draw out the glue. When the bottom of the press plate body 1 contacts the bottom of the glue bucket, there is no pressure in the glue bucket. The floating plate 202 moves under the action of gravity and the glue pressure in the glue channel to seal the glue inlet 103. Finally, when the press plate body 1 is removed from the glue bucket, the glue inlet 103 is in a closed state, avoiding direct flow back to the empty glue bucket when changing glue buckets, greatly reducing glue waste, improving glue utilization, and reducing the cost of glue for enterprises.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this utility model is to provide an adhesive pressing plate, which, through an anti-drip structure, can greatly reduce adhesive waste and effectively improve adhesive utilization.

[0035] Another core aspect of this invention is to provide a glue supply device that includes the aforementioned glue pressure plate.

[0036] Please refer to Figure 3 A glue pressing plate includes a pressing plate body 1 and an anti-drip component 2. The pressing plate body 1 includes a glue passage 101 that passes through the pressing plate body 1. The two ends of the glue passage 101 are a glue inlet 103 and a glue outlet 102, respectively. The anti-drip component 2 includes a floating plate 202 installed on the pressing plate body 1. The floating plate 202 can move relative to the pressing plate body 1 so that the floating plate 202 controls the opening and closing of the glue inlet 103. When the floating plate 202 is only subjected to gravity, the floating plate 202 is in a closed glue inlet 103 state.

[0037] It should be noted that in this embodiment of the present invention, the glue outlet 102 of the pressure plate body 1 is connected to the glue supply device. Specifically, the glue outlet 102 is connected to the plunger pump, and the glue in the glue bucket is sucked out by the plunger pump.

[0038] Optionally, in some embodiments, the glue inlet 103 of the pressure plate body 1 is provided with a stepped cross-section formed by a first opening and a second opening, wherein the diameter of the first opening is smaller than that of the second opening, and the diameter of the floating plate 202 is the same as that of the first opening, so that the floating plate 202 can slide in the first opening. The first opening is located below the second opening, and an annular contact plate is provided below the first opening. When the floating plate 202 is only subjected to gravity, the floating plate 202 moves downward and contacts the contact plate, thereby closing the glue inlet 103. When the pressure plate body 1 moves downward in the glue bucket, the glue pushes the floating plate 202 upward, so that the floating plate 202 enters the second opening, the diameter of the second opening is larger than that of the floating plate 202, and at this time the glue inlet 103 is opened.

[0039] In use, the floating plate 202 is installed on the pressure plate body 1, allowing the floating plate 202 and the pressure plate body 1 to move relative to each other. This allows the floating plate 202 to control the opening and closing of the glue inlet 103. The pressure plate body 1 is placed inside the glue bucket, and the glue outlet 102 of the pressure plate body 1 is connected to a plunger pump. The plunger pump is used to draw out the glue. When the bottom of the pressure plate body 1 contacts the bottom of the glue bucket, there is no pressure inside the glue bucket. The floating plate 202 moves under the action of gravity and the glue pressure in the glue channel to seal the glue inlet 103. Ultimately, when the pressure plate body 1 is removed from the glue bucket, the glue inlet 103 is in a closed state, preventing the glue from flowing directly back to the empty glue bucket when changing the glue bucket. This greatly reduces glue waste, improves glue utilization, and lowers the cost of glue for enterprises. It also prevents glue from dripping onto the bottom plate during bucket changes, reducing the difficulty and intensity of manual cleaning.

[0040] Please refer to Figure 3 In some embodiments, the anti-drip assembly 2 further includes a fixing plate 201, which is fixedly installed on the glue inlet 103. The fixing plate 201 is provided with at least one glue passage 3. The floating plate 202 is located on the side of the fixing plate 201 close to the pressure plate body 1. When the floating plate 202 is only subjected to gravity, the floating plate 202 contacts the fixing plate 201 to close the glue passage 3. That is, the opening and closing control of the glue inlet 103 is achieved through the cooperation of the fixing plate 201 and the floating plate 202.

[0041] In the above embodiment, the fixed plate 201 is located below the floating plate 202. The diameter of the fixed plate 201 is larger than that of the floating plate 202, and the diameter of the glue inlet 103 is also larger than that of the floating plate 202. Under its own weight, the floating plate 202 will adhere tightly to the fixed plate 201. Therefore, when the floating plate 202 contacts the fixed plate 201, it closes the glue inlet 103, thus achieving closure of the glue inlet 103. When the pressure plate body 1 moves downwards within the glue container, the glue pushes the floating plate 202 upwards. Therefore, when the floating plate 201... When the pressure plate 1 detaches from the fixed plate 201, the glue inlet 103 is in the open state. The glue is injected through the gap between the floating plate 202 and the glue inlet 103. After the bottom of the pressure plate body 1 contacts the bottom of the glue bucket, there is no pressure inside the glue bucket. The floating plate 202 moves under the action of gravity and the glue pressure in the glue channel to close the glue inlet 103. Finally, when the pressure plate body 1 detaches from the glue bucket, the glue inlet 103 is in the closed state, which avoids the glue flowing back to the empty glue bucket when changing the glue bucket and greatly reduces the waste of glue.

[0042] Please refer to Figure 1 In some embodiments, the fixed plate 201 has a disc-shaped structure with three glue inlets 3 evenly distributed along the axis of the fixed plate 201. The floating plate 202 is an annular structure coaxial with the fixed plate 201. By providing multiple glue inlets 3, the glue throughput is increased. By using an annular structure coaxial with the fixed plate 201, the glue can quickly enter the pressure plate body 1 after passing through the glue inlets 3 and passing through the annular gaps between the floating plates 202.

[0043] Alternatively, in some embodiments, the number of glue outlets 3 may also be other, such as two, four, etc.

[0044] Optionally, in some embodiments, the glue outlet 3 may be an arc-shaped structure coaxial with the fixing plate 201, or it may be other shapes, such as circles, rectangles or polygons.

[0045] Please refer to Figure 2 In some embodiments, an installation groove 4 is provided at the glue inlet 103, and the fixing plate 201 is located in the installation groove 4 so that the fixing plate 201 and the same side of the pressure plate body 1 are on the same plane. That is to say, by setting the installation groove 4, after the fixing plate 201 is installed on the pressure plate body 1, the side of the pressure plate body 1 that contacts the bottom of the glue bucket remains flat, which is beneficial to further reduce glue residue.

[0046] In the above embodiments, the fixing plate 201 can be fixed in the mounting groove 4 by welding or interference fit.

[0047] Please refer to Figure 3In some embodiments, the fixed plate 201 is provided with at least one guide post 203, and the pressure plate body 1 is provided with a fixing groove 5 for fixing the guide post 203. That is, the pressure plate body 1 is provided with a fixing groove 5 for installing the guide post 203. The guide post 203 is fixed by the fixing groove 5. The guide post 203 is provided on the fixed plate 201. At the same time, the floating plate 202 and the guide post 203 are slidably engaged. Therefore, when the floating plate 202 slides, the guide post 203 can restrict the sliding direction of the floating plate 202, thereby ensuring that it can effectively contact the glue inlet 103, so as to ensure that when the floating plate 202 contacts the fixed plate 201, the glue inlet 103 is completely closed.

[0048] Optionally, in some embodiments, the number of guide posts 203 is three, and they are arranged in a circumferential array along the axis of the fixing plate 201.

[0049] Please refer to Figure 3 In some embodiments, the anti-drip assembly 2 further includes a reset member 204, which is used to control the floating plate 202 to move toward the closed glue inlet 103. The reset member 204 can ensure that when the pressure plate body 1 contacts the bottom of the glue tank, the floating plate 202 can be in close contact with the fixed plate 201 to achieve the closure of the glue inlet 103.

[0050] Optionally, in some embodiments, the reset member 204 is a spring, which is sleeved on the guide post 203 and located between the floating plate 202 and the pressure plate body 1. The spring generates a preload force on the floating plate 202, thereby achieving a pushing force on the floating plate 202 towards the fixed plate 201. The spring force is less than the pushing force of the glue on the floating plate 202 when the pressure plate body 1 moves downward, thereby ensuring that the glue can smoothly push the floating plate 202 to open, so as to open the glue inlet 103.

[0051] In other embodiments, the reset member 204 may also be made of a material with elastic deformation function such as rubber or silicone, and placed between the floating plate 202 and the fixed plate 201, which can also push the floating plate 202 to move towards the fixed plate 201.

[0052] Please refer to Figure 3 In some embodiments, the pressure plate body 1 is provided with at least one pressure plate exhaust channel 7 and at least one glue bucket exhaust channel 6. The pressure plate exhaust channel 7 is connected to the glue passage 101, and the glue bucket exhaust channel 6 passes through the pressure plate body 1 and the fixing plate 201. That is, when the pressure plate body 1 enters the glue bucket, the glue bucket exhaust channel 6 is opened first to discharge the residual air in the glue bucket so that the pressure plate body 1 can enter the glue bucket.

[0053] Optionally, in some embodiments, the pressure plate exhaust channel 7 and the glue barrel exhaust channel 6 are respectively provided with a pressure plate exhaust plug and a glue barrel exhaust plug to facilitate the sealing and opening of the pressure plate exhaust channel 7 and the glue barrel exhaust channel 6.

[0054] Please refer to Figure 4 In some embodiments, the pressure plate body 1 is provided with an annular sealing groove 8, and a sealing element 9 for contacting and sealing with the glue bucket is provided in the sealing groove 8, so as to ensure the sealing between the pressure plate body 1 and the inner wall of the glue bucket.

[0055] In the above embodiments, the sealing element 9 may be made of materials such as rubber or silicone, and has elastic deformation function to improve its sealing performance.

[0056] When the pressure plate body 1 enters the new glue bucket, a seal is formed between the seal 9 and the inner wall of the glue bucket. After the glue bucket vent plug is manually removed, the air inside the glue bucket is discharged to the outside through the glue bucket vent channel and the pressure plate vent channel. After the pressure plate body 1 contacts the glue surface, under the action of the glue surface pressure inside the bucket, the floating plate 202 experiences a thrust greater than the spring force. The glue inside the glue bucket enters the pressure plate body 1 through the annular opening of the fixed plate 201 and the circular opening of the floating plate 202. When the glue overflows from the top of the glue bucket vent channel, the glue bucket vent plug is manually reinstalled, and the venting is completed.

[0057] When the plunger pump basket moves upward, the pressure inside the pressure plate body 1 decreases, the floating plate 202 is subjected to the pressure of the rubber surface, compresses the spring and moves upward; the rubber in the rubber bucket flows into the inner cavity of the pressure plate to realize the replenishment of rubber in the pressure plate.

[0058] When the plunger pump basket moves downward, the pressure inside the pressure plate body 1 increases. The floating plate 202 is pushed downward by the spring and comes into close contact with the fixed plate 201 to achieve a seal. When the pressure inside the pressure plate is too high, the glue in the pressure plate cavity flows back into the glue bucket through the pressure plate exhaust passage and the glue bucket exhaust passage, thereby reducing the pressure inside the pressure plate.

[0059] An adhesive supply device, comprising an adhesive pressure plate according to any one of the above.

[0060] In other words, the key point of this utility model is: installing a floating plate 202 on the pressure plate body 1, and enabling the floating plate 202 and the pressure plate body 1 to move relative to each other, so that the floating plate 202 controls the opening and closing of the glue inlet 103. The pressure plate body 1 is placed in the glue bucket, and the glue outlet 102 of the pressure plate body 1 is connected to a plunger pump. The plunger pump is used to draw out the glue. When the bottom of the pressure plate body 1 contacts the bottom of the glue bucket, there is no pressure in the glue bucket. The floating plate 202 moves under the action of gravity and the glue pressure in the glue channel to achieve the sealing of the glue inlet 103. Finally, when the pressure plate body 1 is removed from the glue bucket, the glue inlet 103 is in a closed state, avoiding direct flow back to the empty glue bucket when changing the glue bucket, greatly reducing glue waste, improving glue utilization, reducing the cost of glue for enterprises, and also preventing glue from dripping onto the bottom plate during the interval of changing buckets, reducing the difficulty and intensity of manual cleaning.
