[0002] Currently, the pressure plate bodies at the front end of automotive glue application fluid transportation are all conical plate bodies, and the movement mode of the plate body is a follow-up type.

[0003] Due to the physical structure characteristics of the conical plate body, when the packaging glue is used up, a part of the glue will remain in the conical structure of the conical plate body, resulting in a waste of about 1.5%. In addition, due to the pollution nature of the glue, special treatment is required, which increases the cost. In addition, the traditional pressure plate has a follow-up movement mode. When pressing to the bottom of the glue plate, air will remain, and the glue remaining inside the packaging needs to be discharged, which will cause another waste of about 1%.

Specific embodiments

[0020] The present invention will be further described below in conjunction with the specification drawings and embodiments.

[0021] Embodiment 1 This embodiment discloses a special pressure plate for a new type of energy-saving and environment-friendly vacuum gluing machine, which is adapted to a packaging glue bucket; as Figure 1 shown, it includes: A pressure plate body 16 with a predetermined thickness. The bottom surface of the pressure plate body 16 in this embodiment is a plane. At the same time, in order not to affect the normal glue discharge, a discharge groove body is opened at the central position of the pressure plate body 16. Further, the discharge groove body is a cone structure. Different from the traditional conical shape at the bottom of the pressure plate body (to achieve better fluid gathering performance inside), when the plate body runs to the bottom of the glue packaging bucket and then withdraws, the conical bottom of the traditional glue plate will leave residual glue of the entire conical body, while this flat-bottom glue plate body will not leave glue residue, saving about 1.5% of waste.

[0022] At the same time, in order to achieve the filtering effect, a filter screen 11 is arranged inside the discharge groove body, and the filter screen 11 is installed on the pressure plate body 16 by using a discharge connection ring 14. The discharge connection ring 14 is also used to connect with a pipeline for transporting the colloid, so as to realize the filtering effect when the glue enters through the filter screen opening of the plate body after the vacuum pressure plate body enters the packaging glue. In a further embodiment, a sealing member is added to the outer side wall of the pressure plate body 16, and the sealing member acts on the inner wall of the packaging glue bucket at the same time, so that the pressure plate body 16 is in close contact with the packaging glue bucket. Correspondingly, the pressure plate body 16 is also provided with a pull rod main body, and the pull rod cylinder body is also adapted to an external driving member. The external driving member in this embodiment can be an external cylinder, a lead screw assembly or other forms of electric driving members.

[0023] In order to better control the movement state of the pressure plate body 16 and at the same time take into account the quality of the colloid, a gas control member is also installed on the pressure plate body 16. By the position information of the pull rod main body, the working state of the gas control member is adjusted, and the movement control of the pressure plate body 16 and the elimination of the gas in the bucket are realized through inflation and suction.

[0024] Therefore, the tight contact created by the seal creates an independent, sealed cavity between the platen body 16 and the inner wall of the glue barrel. When air is evacuated from the cavity through the two inlet valves, a stable negative pressure is created, using atmospheric pressure to push the platen body 16 downward. When air is added through the inlet valve, a positive pressure is created, pushing the platen body 16 upward. This sealing performance maintains a long-term negative pressure in the cavity, preventing external air from entering the glue barrel. This feature eliminates the need for additional venting when replacing new packaging, reducing the approximately 1% of glue waste caused by venting while ensuring full contact between the platen body 16 and the glue through sustained negative pressure, improving fluid delivery efficiency.

[0025] Close contact prevents glue from escaping from the gap between the platen 16 and the barrel wall. Especially during the downward pressure of the platen 16, this ensures that the glue is evenly squeezed toward the discharge port, rather than leaking from the sides. This not only reduces glue waste but also prevents contamination of the equipment or the work environment, thus meeting energy-saving and environmentally friendly design goals.

[0026] For further reference, Figures 1 to 3 The sealing member includes: a plurality of sealing rings 13 which are sleeved on the outer wall of the pressure plate body 16 in a stacked manner, with two groups being shown as an example.

[0027] In a further embodiment, the tie rod body comprises two sets of guide post cylinders 3 symmetrically mounted on the pressure plate body 16, and lower tie rods 4 movably inserted into corresponding guide post cylinders 3. Each set of lower tie rods 4 is detachably connected to an upper tie rod 5, wherein the upper tie rod 5 is adapted to accommodate an external drive element. The lower tie rods 4 and upper tie rods 5 are fixedly connected after docking via a cylindrical pin 6.

[0028] It is worth mentioning that, specifically, the linear bearings 10 are installed in the mounting holes on both sides of the connecting plate 9, and a fixed connection is achieved through the connecting plate 9. This structural design, with the help of the guiding effect of the linear bearings 10, can effectively constrain the movement trajectory of the pull rod body, reduce the offset and shaking during the movement, thereby ensuring that the entire pressure plate body 16 maintains a high degree of straightness and stability during the up and down movement, and provides reliable support for the precise movement of the pressure plate body 16. In this embodiment, the connecting plate 9 and the pressure plate body 16 are fixedly connected. Specifically, a pump head is installed on the connecting plate 9, the pump head and the pump body are installed together, and the pump body is connected to the rubber disc below. Thereby, the connecting plate 9 and the pressure plate body 16 are fixedly connected, and the sliding state of the connecting plate 9 and the upper pull rod is satisfied.

[0029] At the same time, in order to fix the upper limit stroke of the pull rod body and the buffering effect at the upper and lower limit positions, a buffer block 7 and a buffer bolt 15 are installed at the specified position of the upper pull rod 5 and the bottom of the lower pull rod 4 respectively.

[0030] When the pull rod body runs upward to the extreme position, the buffer block 7 contacts the connecting plate 9, absorbs the impact force through its own elastic deformation, avoids damage to the equipment caused by rigid collision, and at the same time defines the maximum upward travel.

[0031] The buffer bolt 15 is installed at the bottom of the lower pull rod 4. When the pull rod body runs downward to the extreme position, the buffer bolt 15 contacts the bottom of the pressure plate body 16 (or the bottom of the rubber barrel), controls the downward distance through the adjustable design of the bolt (such as adjusting the thread depth), and at the same time uses the buffer material (such as rubber, spring, etc.) at the bolt head to slow down the impact, ensuring the safety and stability of the equipment operation.

[0032] The combined use of the above buffer structures not only realizes the precise control of the movement stroke of the pull rod body, but also reduces mechanical wear through the flexible buffer mechanism and extends the service life of the equipment.

[0033] In another embodiment, the gas control member includes: A plurality of air extraction ports and a plurality of air inflation ports, which are opened on the pressure plate body 16 according to predetermined requirements; each air extraction port and air inflation port is correspondingly equipped with an air suction valve 2 and an air inflation valve 1; A plurality of sensors 12, which are correspondingly installed on one side of the air extraction ports and air inflation ports; the sensors 12 are set to monitor position information.

[0034] Specifically, on the top or side of the pressure plate body 16, a plurality of air extraction ports and air inflation ports are opened according to the principles of fluid mechanics and the operation requirements of the equipment. These ports are distributed symmetrically or in a matrix to ensure that the gas pressure acts uniformly inside the pressure plate body 16 and avoid movement deviation caused by local pressure imbalance. Each air extraction port and air inflation port is correspondingly equipped with an air suction valve 2 and an air inflation valve 1 (such as a one-way valve, solenoid valve, etc.), and the flow direction and flow rate of the gas are controlled by the opening and closing of the valves.

[0035] Among them, the air suction valve 2 is connected to an external vacuum pump. When opened, it can quickly extract the air in the sealed cavity between the pressure plate body 16 and the rubber barrel, form a negative pressure environment, and drive the pressure plate body 16 to move downward; the air inflation valve 1 is connected to a compressed air source. When opened, it injects air into the sealed cavity to form a positive pressure environment and push the pressure plate body 16 to move upward.

[0036] A number of sensors 12 are correspondingly installed on one side of the air extraction port and the air inflation port (such as in the side mounting groove), and are arranged in close proximity to the valve to ensure the timeliness and accuracy of the monitoring signal. When the upper pull rod 5 drives the pressure plate body 16 to move to the upper extreme position (i.e., the buffer block 7 and the connecting plate 9) or the lower extreme position (such as the buffer bolt 15 contacting the bottom of the glue bucket), the sensor 12 immediately detects the position signal and transmits it to the equipment control system; combined with the opening and closing state of the valve, the sensor 12 can determine whether the pressure plate body 16 has completed the preset movement stroke, avoiding abnormal operation caused by gas leakage or mechanical jamming, and at the same time providing feedback data for the closed-loop control of the system.

[0037] In a further embodiment, the pressure plate body 16 is also provided with a plugging port, and a plugging rod 8 is installed in the plugging port. During equipment maintenance, glue type replacement or repair, by disassembling or installing the plugging rod 8, the internal structure can be conveniently operated, while preventing foreign objects from entering or glue leakage, ensuring the sealing and reliability of the equipment operation.

[0038] In summary, when the external power drives the pull rod main body to move downward, when the lower pull rod 4 runs to the bottom of the guide column cylinder body 3, the sensor 12 detects the lower limit position signal and stops the external driving force.

[0039] The control system triggers the opening of the suction valve 2, extracts the air in the sealed cavity through the air extraction port to form a negative pressure, and under the action of the atmospheric pressure, pushes the pressure plate body 16 to continue moving downward until the buffer bolt 15 contacts the bottom of the glue bucket, and the sensor 12 stops suction after detecting the signal again.

[0040] The external power drives the pull rod main body to move upward. When the upper pull rod 5 runs to the top of the guide column cylinder body 3, the sensor 12 detects the upper limit position signal and stops the external driving force; the control system triggers the opening of the inflation valve 1, injects air into the sealed cavity through the air inflation port to form a positive pressure, and pushes the pressure plate body 16 to move upward until the buffer block 7 contacts the connecting plate 9, and the sensor 12 stops inflation after detecting the signal. In this way, the up and down movement is realized.

[0041] Since the replacement of the packaging glue bucket realizes the suction and downward pressure mode, using the suction characteristic of the plate body, the plate body and the inside of the packaging are in a long-term negative pressure state, realizing a continuous downward pressure and suction state, so that there is no excessive packaging air residue after each packaging replacement, and there is no need to exhaust the new packaging after replacement. And due to the principle that there is no more packaging air residue and no need to exhaust after replacement, there is no need to discharge the glue remaining in the packaging, and about 1% of waste can be saved.
