Description

Technical Field

[0001] The invention belongs to the technical field of aluminum cover sealing, and in particular relates to an aluminum cover sealing device for dry fruit filling, and a sealing method for the aluminum cover sealing device for dry fruit filling. Background Art

[0002] Aluminum cans are widely used in various fields due to their lightness, durability, moisture resistance, aroma retention, and excellent sealing properties. To ensure a better seal between the can and its lid, intermittent threads are often installed on the surface of the can and lid to connect the two. Therefore, when the lid is installed, it is necessary to tightly seal the lid against the can opening by rotating and pressing it downward.

[0003] When the aluminum cap adopts the rotary sealing technology, multiple driving mechanisms are required to complete the clamping, rotation and pressing of the aluminum cap. If the threaded connection method between the aluminum cap and the aluminum can is different, the same rotation or pressing speed will cause the aluminum cap to move excessively and deform, affecting the sealing effect of the aluminum cap. Summary of the Invention

[0004] The present invention aims to solve the problems in the prior art and proposes the following technical solutions:

[0005] An aluminum cap sealing device for dried fruit filling comprises: a sealing assembly and a drive assembly, wherein the sealing assembly comprises a sealing ring and two mounting blocks, wherein a plurality of laminating rollers with a rubber layer on their surfaces are rotatably inserted into the inner side of the sealing ring, and the sealing ring comprises two sealing half-rings, which are rotatably inserted into the mounting blocks, and a torsion spring is provided at the insertion position between the sealing half-rings and the mounting blocks;

[0006] After the two sealing half rings form a sealing ring, the rubber layer of multiple fitting rollers contacts the surface of the aluminum cover and deforms to clamp and fix it. The driving assembly drives the sealing ring to rotate through the two mounting blocks so that the aluminum cover is threaded onto the can body, and the fitting rollers rotate along the surface of the aluminum cover to meet the downward movement of the aluminum cover while maintaining the clamping state.

[0007] As a preferred embodiment of the above technical solution, a guide piece is provided on the outside of the sealing half ring, and two guide pieces are circumferentially arranged relative to the center of the sealing ring. A rolling ball is rotatably inserted into the sealing half ring and is fitted with the guide piece.

[0008] As a preferred embodiment of the above technical solution, one end of the guide piece is arranged in an outward-turned shape, and the distance between the outward-turned end of the guide piece and the sealing ring component is increased.

[0009] As a preferred embodiment of the above technical solution, a fixing ring is further included, wherein the driving assembly is located inside the fixing ring, and the fixing ring is used to clamp and fix the tank body. The fixing ring is composed of two fixing half rings that move toward or in opposite directions.

[0010] As a preferred embodiment of the above technical solution, the drive assembly includes a bevel gear, an arc block and two rotating semi-rings, the surface of the arc block is provided with a tooth surface that meshes with the bevel gear, the rotating semi-ring, the sealing semi-ring and the fixed semi-ring are coaxially and vertically arranged, the rotating semi-ring consists of a removal block and a connecting block fixedly connected to the mounting block, and the arc block is fixedly connected to one of the connecting blocks.

[0011] As a preferred embodiment of the above technical solution, a forward and reverse motor is installed on one side of the fixing ring, and an output end of the forward and reverse motor is connected to the bevel gear.

[0012] As a preferred embodiment of the above technical solution, a soft rubber layer is provided on the inner surface of the fixing ring, and the soft rubber layer of the fixing ring contacts and deforms with the surface of the tank body to clamp and fix it.

[0013] The sealing method of the aluminum cap sealing device for dried fruit filling comprises the following steps:

[0014] S1. Place the aluminum cover;

[0015] After the external conveying equipment transports the can body to the sealing position, the aluminum cover is placed on top of the can body from the top;

[0016] S2, fixed tank;

[0017] The two fixed half rings move toward each other to clamp the bottom of the tank, and then the forward and reverse motors work to rotate the bevel gears, driving the arc block, connecting block and mounting block to rotate. Under the push of the two rotating half rings, the removed block then returns to the original fixed half ring;

[0018] S3, clamp the aluminum cover;

[0019] The sealing half ring moves along with the mounting block and passes the outward-turned end of the guide plate. The sealing half ring is pushed and deflected back by the guide plate with the assistance of the rolling ball. The two sealing half rings form a complete sealing ring so that the fitting roller contacts the surface of the aluminum cover.

[0020] S4, tank sealing;

[0021] After the sealing ring drives the aluminum cover to rotate to the sealing position, the forward and reverse motors reverse to make the sealing ring drive the aluminum cover to rotate in the opposite direction, and the fitting roller rotates along the surface of the aluminum cover to meet the downward movement of the aluminum cover while maintaining the clamping state;

[0022] S5, blanking processing;

[0023] When the mounting block enters the outward-turned end of the guide plate, the torsion spring flips the two fixed half rings away from the aluminum cover position. When the removal block enters the other fixed half ring, the two fixed half rings move in the opposite direction to split the sealing device for unloading.

[0024] The beneficial effects of the present invention are:

[0025] 1. Multiple fitting rollers arranged circumferentially inside the sealing ring can clamp and fix the aluminum cap by deforming the rubber soft layer on its surface. When the aluminum cap moves downward along the threads on the can body under the drive of the sealing ring, the fitting rollers rotate along the surface of the aluminum cap, maintaining the clamping fixation while automatically adapting to the downward movement of the aluminum cap, thus preventing the aluminum cap from deforming due to excessive movement, thereby ensuring the sealing effect of the aluminum cap;

[0026] 2. The guide piece can divide the sealing ring into a combined clamping state and an open and disengaged state during the rotation process, so that the two sealing half rings automatically deflect away from the aluminum cover position after the aluminum cover is rotated and installed, so that the fixing ring can normally drive the sealing assembly to be separated without affecting the aluminum cover itself;

[0027] 3. Under the driving force of the two rotating half-rings, the two mounting blocks can be rotated synchronously, and the removal block constituting the rotating half-ring can enter the interior of the other fixed half-ring, so that the fixed ring can be opened and separated when the sealing ring is in the open and disengaged state, making the use of the device more convenient.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0035] Example

[0036] Figure 1-Figure 5 In the embodiment, the aluminum cap sealing device for dried fruit filling comprises: a sealing assembly 10 and a driving assembly 30, wherein the sealing assembly 10 comprises a sealing ring 11 and two mounting blocks 12, wherein a plurality of laminating rollers 13 with a rubber soft layer on the surface are rotatably inserted into the inner side of the sealing ring 11, and the sealing ring 11 comprises two sealing half rings 111, wherein the sealing half rings 111 are rotatably inserted into the mounting blocks 12, and a torsion spring is provided at the insertion position between the sealing half rings 111 and the mounting blocks 12;

[0037] After the two sealing half rings 111 form the sealing ring 11, the rubber layer of multiple fitting rollers 13 contacts the surface of the aluminum cover and deforms to clamp and fix it. The driving assembly 30 drives the sealing ring 11 to rotate through the two mounting blocks 12 so that the aluminum cover is threadedly sleeved on the can body, and the fitting rollers 13 rotate along the surface of the aluminum cover to meet the downward movement of the aluminum cover while maintaining the clamping state.

[0038] It also includes a fixing ring 20, the driving assembly 30 is located in the fixing ring 20, the fixing ring 20 is used to clamp and fix the tank body, and the fixing ring 20 is composed of two fixing half rings 21 that move toward or in opposite directions.

[0039] After the external conveying equipment transports the can body to the sealing position, the aluminum cover is placed on top of the can body from the top, and the external power equipment moves the two fixed half rings 21 toward each other to clamp the bottom of the can body, and the two sealing half rings 111 then form a complete sealing ring 11, and the fitting roller 13 inside it contacts the surface of the aluminum cover to clamp the aluminum cover. In this technical solution, this external power equipment is a cylinder, and then the driving component 30 drives the sealing ring 11 to rotate through the mounting block 12, and the multiple fitting rollers 13 that clamp the aluminum cover then rotate the aluminum cover to perform the sealing work. When the aluminum cover rotates downward along the thread on the surface of the can body, the fitting roller 13 rotates along the surface of the aluminum cover to meet the downward movement of the aluminum cover while maintaining the clamping state.

[0040] The multiple fitting rollers 13 circumferentially arranged inside the sealing ring 11 can clamp and fix the aluminum cover by deforming the rubber soft layer on its surface. When the aluminum cover is driven by the sealing ring 11 and moves downward along the thread on the surface of the can body, the fitting rollers 13 rotate along the surface of the aluminum cover, and can automatically adapt to the downward movement of the aluminum cover while maintaining the clamping and fixing, thereby avoiding deformation of the aluminum cover due to excessive movement, thereby ensuring the sealing effect of the aluminum cover.

[0041] Figure 1-Figure 3 In the embodiment, a guide piece 14 is provided on the outside of the sealing half ring 111 , and two guide pieces 14 are circumferentially arranged relative to the center of the sealing ring 11 . A rolling ball 15 that is rotatably inserted into the sealing half ring 111 and is fitted with the guide piece 14 .

[0042] One end of the guide piece 14 is arranged in an outward-turned shape, and the distance between the outward-turned end of the guide piece 14 and the sealing ring 11 is increased.

[0043] When the mounting block 12 enters the outward-turned end of the guide piece 14, the torsion spring in a torsion state flips the two fixed half rings 21 away from the aluminum cover position, and the two fixed half rings 21 move in opposite directions to separate the sealing device for blanking.

[0044] The guide piece 14 provided can divide the sealing ring 11 into a combined clamping state and an open and disengaged state during the rotation process, so that the two sealing half rings 111 automatically deflect away from the aluminum cover position after the aluminum cover is rotated and installed, so that the fixing ring 20 can normally drive the sealing assembly 10 to be disassembled without affecting the aluminum cover itself.

[0045] Figure 4-Figure 5 In the figure, the driving assembly 30 includes a bevel gear 31, an arc block 32 and two rotating semi-rings 33. The surface of the arc block 32 is provided with a tooth surface that meshes with the bevel gear 31. The rotating semi-ring 33, the sealing semi-ring 111 and the fixed semi-ring 21 are coaxially arranged vertically. The rotating semi-ring 33 consists of a removal block 331 and a connecting block 332 fixedly connected to the mounting block 12. The arc block 32 is fixedly connected to one of the connecting blocks 332.

[0046] A forward and reverse motor 34 is installed on one side of the fixing ring 20 , and an output end of the forward and reverse motor 34 is connected to the bevel gear 31 .

[0047] The inner surface of the fixing ring 20 is provided with a soft rubber layer, and the soft rubber layer of the fixing ring 20 is deformed when in contact with the surface of the tank body to clamp and fix it.

[0048] When the drive assembly 30 is used, the forward and reverse motors 34 work to rotate the bevel gear 31, driving the arc block 32, the connecting block 332 and the mounting block 12 to rotate. The rotating half ring 33 pushes the other rotating half ring 33 to rotate inside the fixed ring 20, thereby pushing the other mounting block 12. The removal blocks 331 of the two rotating half rings 33 are exchanged into the other fixed half ring 21, making it convenient for the fixed ring 20 to be disassembled at will.

[0049] Under the pushing action of the two rotating half rings 33, the two mounting blocks 12 can be rotated synchronously, and the removal block 331 constituting the rotating half ring 33 can enter the interior of the other fixed half ring 21, so that the sealing ring 11 can be opened and separated by the fixed ring 20 when it is in the open and disengaged state, making the use of the device more convenient.

[0050] The sealing method of the aluminum cap sealing device for dried fruit filling comprises the following steps:

[0051] S1. Place the aluminum cover;

[0052] After the external conveying equipment transports the can body to the sealing position, the aluminum cover is placed on top of the can body from the top;

[0053] S2, fixed tank;

[0054] The two fixed half rings 21 move toward each other to clamp the bottom of the tank, and then the forward and reverse motor 34 works to rotate the bevel gear 31, driving the arc block 32, the connecting block 332 and the mounting block 12 to rotate. Under the push of the two rotating half rings 33, the moving block 331 then returns to the original fixed half ring 21.

[0055] S3, clamp the aluminum cover;

[0056] The sealing half ring 111 moves along with the mounting block 12 and passes the outward-turned end of the guide piece 14. The sealing half ring 111 is pushed and deflected back by the guide piece 14 with the assistance of the rolling ball 15. The two sealing half rings 111 form a complete sealing ring 11 so that the fitting roller 13 contacts the surface of the aluminum cover.

[0057] S4, tank sealing;

[0058] After the sealing ring 11 drives the aluminum cover to rotate to the sealing position, the forward and reverse motor 34 reverses to make the sealing ring 11 drive the aluminum cover to rotate in the opposite direction, and the fitting roller 13 rotates along the surface of the aluminum cover to meet the downward movement of the aluminum cover while maintaining the clamping state;

[0059] S5, blanking processing;

[0060] When the mounting block 12 enters the outward-turned end of the guide piece 14, the torsion spring flips the two fixed half rings 21 away from the aluminum cover position, and the removal block 331 enters the other fixed half ring 21. The two fixed half rings 21 move in the opposite direction to split the sealing device for unloading processing.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
