DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 9 , the present invention provides a technical solution: Embodiment 1, a high-viscosity glue degassing device with filler, comprises: a mounting seat 1, a degassing cylinder 5 and a heating element 6.

[0021] Specifically, a cylinder sleeve 2 is fixedly installed on the upper surface of the mounting seat 1, and a hollow cylinder rod 3 is movably inserted and penetrated in the inner cavity of the cylinder sleeve 2. The cylinder rod 3 is vertically arranged, and the cylinder rod 3 can slide up and down in the vertical direction, thereby changing its own height position, and the cylinder rod 3 can transport the glue from top to bottom. A negative pressure cylinder 4 is fixedly installed on the lower surface of the mounting seat 1, and the lower end of the cylinder rod 3 penetrates downward through the mounting seat 1 and extends to the inner cavity of the negative pressure cylinder 4, and a storage cylinder 41 is fixedly installed in the inner cavity of the negative pressure cylinder 4. The storage cylinder 41 and the negative pressure cylinder 4 are concentrically arranged, and a bell mouth 411 is opened at the upper end of the storage cylinder 41. The inner cavity of the upper end of the storage cylinder 41 is connected with the inner cavity of the negative pressure cylinder 4. Secondly, the degassing cylinder 5 is vertically slidably installed in the inner cavity of the storage cylinder 41, and the degassing cylinder 5 is movably sleeved on the outer side of the lower end of the cylinder rod 3, combined with Figure 2 and Figure 3 As shown, when the cylinder rod 3 slides up and down in the vertical direction, the cylinder rod 3 can drive the degassing cylinder 5 to move accordingly, but the degassing cylinder 5 can slide relatively for a certain distance on the outside of the cylinder rod 3, so the movement of the cylinder rod 3 and the degassing cylinder 5 has a certain delay, as follows: ① When the cylinder rod 3 moves upward to the upper end of the stroke, the degassing tube 5 is in a state of being away from the cylinder rod 3 under the action of its own gravity. At this time, the cylinder rod 3 moves downward, and the degassing tube 5 can move with it until the degassing tube 5 enters the inner cavity of the storage tube 41 from the inner cavity of the negative pressure tube 4. The degassing tube 5 seals the inner cavity of the storage tube 41. When the degassing tube 5 continues to move downward, the pressure in the inner cavity of the storage tube 41 gradually increases until it exceeds the gravity of the degassing tube 5 itself, and the degassing tube 5 can no longer move downward, but the cylinder rod 3 continues to move downward until the cylinder rod 3 supports the degassing tube 5. The degassing tube 5 will continue to move downward only after being subjected to the pressure of the cylinder rod 3; in this process, the pressure in the inner cavity of the storage tube 41 gradually increases, and the glue accumulated in the inner cavity of the storage tube 41 can be squeezed out from the lower end; ② Then the cylinder rod 3 moves upward. At this time, the degassing cylinder 5 moves synchronously with the cylinder rod 3 for a certain distance under the action of the pressure in the inner cavity of the storage cylinder 41, until the pressure in the inner cavity of the storage cylinder 41 decreases to less than the gravity of the degassing cylinder 5, and the degassing cylinder 5 stops moving upward, but the cylinder rod 3 continues to move upward. After the cylinder rod 3 moves up for a certain distance, it generates a pulling force on the degassing cylinder 5 until the degassing cylinder 5 is pulled out of the inner cavity of the storage cylinder 41; in this process, the pressure in the inner cavity of the storage cylinder 41 gradually decreases to form a negative pressure, so that the glue in the upper feeding pipe can be drawn into the inner cavity of the degassing cylinder 5 through the cylinder rod 3 for temporary accumulation; In addition, a feeding hole 51 is provided on the lower end surface of the degassing cylinder 5, and the inner diameter of the feeding hole 51 gradually decreases from top to bottom to form a truncated cone shape, such as Figure 3 and Figure 4 As shown, the glue in the inner cavity of the degassing cylinder 5 can pass through the inner cavity of the discharge hole 51 under pressure and be discharged from the inner cavity of the degassing cylinder 5. Combined with the above description, it can be seen that: ① When the pressure in the inner cavity of the material storage barrel 41 is relatively high and forms high pressure, the degassing barrel 5 is close to the cylinder rod 3, and the lower end surface of the cylinder rod 3 will block the material discharge hole 51. At this time, the inner cavity of the degassing barrel 5 is disconnected from the inner cavity of the material storage barrel 41, and the downward movement of the degassing barrel 5 will squeeze the glue in the inner cavity of the material storage barrel 41 out of the inner cavity of the material storage barrel 41; ② When the pressure in the inner cavity of the material storage barrel 41 is relatively small and forms a negative pressure, the degassing barrel 5 is in a state of being away from the cylinder rod 3, and the negative pressure in the inner cavity of the material storage barrel 41 can draw the glue in the inner cavity of the degassing barrel 5 into the inner cavity of the material storage barrel 41 through the discharge hole 51, and because the inner diameter of the lower end opening of the discharge hole 51 is relatively small, the high-viscosity glue discharged from the discharge hole 51 will form a long and thin noodle-like structure. At this time, if there are bubbles in the glue, the noodle-like glue will break at the bubbles, thereby achieving the effect of degassing the glue. After that, the degassing glue is accumulated at the bottom of the inner cavity of the material storage barrel 41 under the action of gravity, so as to be squeezed out from the inner cavity of the material storage barrel 41 later; Furthermore, the heating element 6 is installed inside the upper and lower ends of the cylinder sleeve 2. The heating element 6 is annular and movably sleeved on the outer side of the cylinder rod 3. The heating element 6 is a heating wire known in the prior art, such as Figure 2 As shown, during the up and down reciprocating movement of the cylinder rod 3, the heating element 6 can fully heat the cylinder rod 3, so that all positions of the inner cavity of the cylinder rod 3 are in a warm state. When the glue flows from top to bottom in the inner cavity of the cylinder rod 3, the glue can be gradually heated, so that the bubbles in the glue expand and increase in volume after being heated, thereby making it easier to degasify the fine bubbles and reducing the fine bubbles mixed in the glue that affect the degassing effect. In addition, it is worth noting that the heating temperature of the cylinder rod 3 by the heating element 6 needs to be determined according to the properties of the glue itself during actual use. The heating temperature needs to be controlled at the highest temperature without affecting the deterioration of the glue. The temperatures at which different glues deteriorate when heated are different, which will not be repeated here.

[0022] In order to achieve the blocking of the inner cavity at the lower end of the cylinder rod 3, the present application also has a sealing boss 52 fixedly arranged in the middle of the inner wall of the lower end of the degassing cylinder 5, and the upper end of the sealing boss 52 is provided with a chamfer, and the sealing boss 52 is inserted into the inner cavity of the lower end of the cylinder rod 3 from bottom to top, such as Figure 4 and Figure 3 As shown, when the degassing tube 5 and the cylinder rod 3 move relative to each other and the degassing tube 5 is close to the cylinder rod 3, the sealing boss 52 can be inserted into the inner cavity of the lower end of the cylinder rod 3, and the lower end surface of the cylinder rod 3 just abuts against the inner wall of the lower end of the degassing tube 5, thereby sealing the discharge hole 51 and ensuring that the inner cavities of the storage tube 41, the degassing tube 5 and the cylinder rod 3 are disconnected. At this time, the glue in the inner cavity of the cylinder rod 3 cannot enter the inner cavity of the storage tube 41. On the contrary, the degassing tube 5 is away from the cylinder rod 3. When the cylinder rod 3 is in operation, the inner cavities of the cylinder rod 3, the degassing cylinder 5 and the storage cylinder 41 are connected in sequence. The glue in the inner cavity of the cylinder rod 3 can pass through the degassing cylinder 5 and the inner cavity of the discharge hole 51 in sequence and enter the inner cavity of the storage cylinder 41. In addition, the discharge hole 51 is provided with multiple holes and is distributed in a ring array around the sealing boss 52. It can be used to quickly discharge the glue in the inner cavity of the degassing cylinder 5 from the inner cavity of the storage cylinder 41 and form a structure of multiple noodle-like structures, thereby improving the degassing efficiency of the bubbles in the glue.

[0023] In order to improve the sealing between the degassing cylinder 5 and the inner wall of the storage cylinder 41, the present application also has a sealing plug 53 fixedly sleeved on the outer side of the lower end of the degassing cylinder 5, a deformation groove 54 is opened at the edge of the lower surface of the sealing plug 53, and the cross-section of the deformation groove 54 is an inverted "V" shape, and the sealing plug 53 and the inner wall of the storage cylinder 41 are interference fit, combined with Figure 4 and Figure 3 It can be seen that the setting of the sealing plug 53 can be used to improve the sealing between the degassing cylinder 5 and the inner cavity of the storage cylinder 41, ensuring that the degassing cylinder 5 can control the pressure in the inner cavity of the storage cylinder 41 when moving up and down, and the setting of the deformation groove 54 makes the sealing plug 53 have better elastic deformation ability, which cooperates with the bell mouth 411 to make it easier for the degassing cylinder 5 to slide into the inner cavity of the storage cylinder 41 from the top of the storage cylinder 41.

[0024] In order to prevent the degassing cylinder 5 and the cylinder rod 3 from separating from each other, the present application also has an outer retaining ring 55 fixedly provided on the upper end of the degassing cylinder 5, and the outer retaining ring 55 is movably sleeved on the lower end of the outer wall of the cylinder rod 3, and a lower retaining ring 31 is fixedly provided on the lower end of the cylinder rod 3, and the lower retaining ring 31 is slidably installed in the inner cavity of the degassing cylinder 5 and adapted thereto, and the outer retaining ring 55 is used to limit the lower retaining ring 31, so that the lower retaining ring 31 can only slide in the inner cavity of the degassing cylinder 5 and will not detach from the inner cavity of the degassing cylinder 5, and the outer retaining ring 55 cooperates with the lower retaining ring 31 to prevent the degassing cylinder 5 and the cylinder rod 3 from separating when they move away from each other.

[0025] In order to input glue to the upper end of the cylinder rod 3, the present application also has a feeding sleeve 7 movably sleeved on the outer side of the upper end of the cylinder rod 3, an upper retaining ring 32 adapted to the feeding sleeve 7 is fixedly provided on the upper end of the cylinder rod 3, an annular sealing cover 73 is fixedly provided on the lower end of the feeding sleeve 7, and the annular sealing cover 73 is movably sleeved on the upper end of the outer wall of the cylinder rod 3, such as Figure 5 As shown, the annular cover 73 limits the upper retaining ring 32, so that the upper retaining ring 32 can only slide up and down in the inner cavity of the feeding sleeve 7 without being separated from the feeding sleeve 7. The feeding sleeve 7 can transport the external glue into the inner cavity of the cylinder rod 3. The position of the feeding sleeve 7 itself remains fixed and does not move with the movement of the cylinder rod 3. The cylinder rod 3 always remains connected with the inner cavity of the feeding sleeve 7 during the up and down movement.

[0026] In order to prevent glue from leaking from the upper end of the cylinder rod 3, the present application also has a feed interface 71 provided at the upper end of the feed sleeve 7, and the feed interface 71 is connected to the external glue delivery pipe, and the inner cavity of the feed interface 71 is provided with a feed check valve 72. The feed sleeve 7 itself is fixed in position by a stand, and the external glue can flow into the inner cavity of the feed sleeve 7 in one direction under the control of the feed check valve 72, and then enter the inner cavity of the cylinder rod 3. However, the glue in the inner cavity of the feed sleeve 7 cannot be discharged from the feed interface 71 due to the action of the feed check valve 72. Therefore, even if the pressure in the inner cavity of the cylinder rod 3 increases when the cylinder rod 3 moves, the glue in the inner cavity of the cylinder rod 3 will not leak from the upper end.

[0027] In order to install and position the negative pressure cylinder 4 and the storage cylinder 41, the present application also has a base 8 arranged below the mounting seat 1, the lower end of the negative pressure cylinder 4 and the lower end of the storage cylinder 41 are fixedly connected to the base 8, and the outer side of the negative pressure cylinder 4 and the outer side of the storage cylinder 41 are respectively fixedly installed with a reinforcing rod 43 and a positioning rod 412 fixedly connected to the base 8. The setting of the base 8 is mainly used to install and position the negative pressure cylinder 4 and the storage cylinder 41, and the setting of the reinforcing rod 43 and the positioning rod 412 can be used to reinforce the negative pressure cylinder 4 and the storage cylinder 41 to prevent the negative pressure cylinder 4 and the storage cylinder 41 from tilting and pressure damage.

[0028] In order to discharge the glue in the inner cavity of the storage barrel 41, the present application also has a discharge valve seat 81 fixedly installed on the side of the base 8, a discharge slot 82 is opened inside the base 8, and a discharge check valve 83 is installed in the inner cavity of the discharge valve seat 81. The two ends of the discharge slot 82 are respectively connected to the discharge check valve 83 and the inner cavity of the storage barrel 41. Figure 7As shown, the inner cavity of the discharge slot 82 is connected with the inner cavity of the storage barrel 41, and the glue in the inner cavity of the storage barrel 41 can be discharged through the discharge slot 82. However, due to the presence of the discharge one-way valve 83, even if the inner cavity of the storage barrel 41 forms a negative pressure, the discharged glue will not re-enter the inner cavity of the storage barrel 41 through the discharge slot 82. Therefore, the glue in the inner cavity of the cylinder rod 3 can only be drawn into the inner cavity of the cylinder rod 3 after the negative pressure is formed in the inner cavity of the storage barrel 41. The feeding sleeve 7, the cylinder rod 3, the degassing cylinder 5 and the inner cavity of the storage barrel 41 of this device are connected in sequence, and the glue enters from the upper end of the feeding sleeve 7 and is discharged from the lower end of the storage barrel 41. The feed one-way valve 72 and the discharge one-way valve 83 are respectively provided at the inlet and outlet positions of the glue to control the flow direction of the glue. The up and down movement of the cylinder rod 3 and the degassing cylinder 5 can be used to control the pressure between the degassing cylinder 5 and the inner cavity of the storage barrel 41, thereby forming a pressure difference, so that the glue can be automatically transported under the action of the pressure difference.

[0029] In order to reduce the impact force on the base 8 when the degassing cylinder 5 moves downward, the present application also has a partition 413 provided in the lower end inner cavity of the storage cylinder 41, and the partition 413 covers the opening at one end of the discharge slot 82, and a plurality of evenly distributed strip slots 414 are penetrated through the surface of the partition 413. The partition 413 itself is made of flexible material, which can be used to reduce the impact force on the base 8 when the degassing cylinder 5 moves downward, thereby reducing the possibility of malfunction and damage of the degassing cylinder 5 after long-term use.

[0030] In order to control the up and down movement of the cylinder rod 3, the present application also has a cavity in the middle of the cylinder sleeve 2, and a cylinder piston 21 adapted thereto is slidably installed in the cavity, and the cylinder piston 21 is fixedly sleeved on the outer side of the cylinder rod 3, such as Figure 2 As shown, when the cylinder sleeve 2 moves up and down, it can drive the cylinder rod 3 to move up and down synchronously. A cylinder control valve 22 and an air extraction valve 42 are respectively installed at both ends of the mounting seat 1. The cylinder control valve 22 is connected to the cavity in the middle of the cylinder sleeve 2. The cylinder control valve 22 is externally connected to a controller and a compressor. The cylinder piston 21 slides up and down by controlling the air pressure in the cavity in the middle of the cylinder sleeve 2, thereby driving the cylinder rod 3 to move up and down. The air extraction valve 42 is connected to the inner cavity of the negative pressure cylinder 4. The air extraction valve 42 is externally connected to a pressure gauge and an air extraction pump, which are used to control and maintain the pressure in the inner cavity of the negative pressure cylinder 4, so as to promptly extract the air after the bubble bursts.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
