Description

Technical Field

[0001] The present application relates to the technical field of packaging and processing equipment, and more specifically, to a side sealing mechanism of a cream paper packaging machine. Background Art

[0002] With the development of production technology and the improvement of living standards, people's choice and demand for paper towels are changing with each passing day. Cream paper, as a product used for cosmetics and skin care, is favored and loved by consumers. In the production process of cream paper, packaging machines are often used to seal the side of the product before putting it on the market.

[0003] Currently, most packaging machines on the market are of the fixed sealing type. For example, a Chinese patent (authorization publication number CN218343875U) discloses a side sealing mechanism for a compression packaging machine, comprising a workbench, a flattening mechanism, and a side sealing mechanism. A frame is fixedly mounted on the top of the workbench, and the side sealing mechanism and the flattening mechanism are mounted inside the frame. The flattening mechanism comprises a motor and a fixed frame. A bidirectional threaded rod is fixedly mounted on the output shaft of the motor. The motor is fixedly mounted on the right side of the motor. A moving block is threadedly connected to the left and right sides of the bidirectional threaded rod. A slider is fixedly mounted on the top of the moving block. The fixed frame is fixedly mounted inside the frame. A slide groove is formed on the inner top wall of the fixed frame. The slider is slidably connected in the slide groove. An electric push rod is fixedly mounted on the bottom of the moving block. A flat plate is fixedly mounted on the bottom of the electric push rod. The side sealing mechanism comprises a first cylinder fixedly mounted on the top of the frame. The first cylinder is fixedly mounted on the top of the frame. The side sealing mechanism of this compression packaging machine achieves the purpose of automatic flattening.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the side sealing mechanism may cause the position of the packaging bag to shift during the process of side sealing the outer packaging after processing and packaging, which is prone to the defect of side sealing angle deviation. At the same time, the seals are mostly long strips with a single style, which cannot reflect the uniqueness and difference of the packaged products. Utility Model Content

[0005] In order to solve the above problems, the present application provides a side sealing mechanism of a cream paper packaging machine.

[0006] The side sealing mechanism of a cream paper packaging machine provided in this application adopts the following technical solution:

[0007] The top end of the lifting block is connected with the lifting block by the spring, and the bottom end of the lifting block is connected with the lifting block by the spring.

[0008] Furthermore, the material of the fixing block and the pressure block are both nitrile rubber.

[0009] Through the above technical solution, the use of nitrile rubber material makes the fixed block and the pressure block have a certain toughness and can withstand multiple side sealing operations.

[0010] Furthermore, the groove size and length of the card slot are arranged in increasing order from bottom to top.

[0011] Through the above technical solution, the packaging bags are placed between grooves of different sizes and lengths according to the sizes of the packaging bags to be side-sealed and the different requirements of the side sealing positions of different styles of products. On the one hand, it can prevent the position displacement of the packaging bags and the side sealing angle deviation during the side sealing process of the outer packaging to a certain extent. On the other hand, it can also meet the different requirements of the side sealing positions of different sizes of packaging bags and different styles of products.

[0012] Furthermore, the support seat and the slide rod are both provided with a group, and the connecting rod passes through the movable notch and is provided between the fixed block and the slide rod.

[0013] Through the above technical solution, the connecting rod is set in the movable groove. When the first cylinder drives the connecting rod installed at its output end to move up and down, it further drives the limit block installed at the other end to move up and down. Grooves of different sizes are arranged inside the limit block. By adjusting the height of the limit block, it can be adapted to packaging products of different thicknesses.

[0014] Furthermore, the telescopic rod passes through the mounting plate and extends to the other side of the mounting plate while being located directly above the pressure block.

[0015] Through the above technical solution, the other end of the telescopic rod is fixedly connected to the connecting block and the pressing block. The telescopic rod drives the pressing block to move downward. The packaging bag to be side-sealed is placed between the pressing block and the pressure block. The side sealing operation of the packaged product is completed by mutual extrusion of the two blocks.

[0016] Furthermore, the pressure block and the printing block are both in an inverted L shape, and the printing blocks are provided in sets with different styles of prints.

[0017] Through the above technical solution, the printing block is equipped with multiple groups that can be connected to the connecting block through threads. At the same time, the lower surface of the printing block is provided with multiple groups of prints of different styles, which can be adjusted and replaced at any time. The side-sealed packaging bags with different prints can reflect the uniqueness and difference of the packaged products, making the processed products more popular with consumers.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] According to the size of the packaging bag to be side-sealed and the different requirements of the side sealing position of different styles of products, the packaging bag is placed between grooves of different sizes and lengths. On the one hand, it can prevent the position displacement of the packaging bag and the side sealing angle deviation during the side sealing process of the outer packaging to a certain extent. On the other hand, it can also meet the different requirements of the side sealing position of different sizes of packaging bags and different styles of products. The printing block is equipped with multiple groups that can be connected to the connecting block by threads. At the same time, the lower surface of the printing block is provided with multiple groups of different styles of prints, which can be adjusted and replaced at any time. Side-sealed packaging bags with different prints can reflect the uniqueness and difference of the packaged products. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The embodiment of the present application discloses a side sealing mechanism of a cream paper packaging machine, please refer to Figure 1, including a base plate 1, the upper surface of the base plate 1 is fixedly connected to a support base 2, an installation box 3 and a vertical plate 4, a limiting groove 201 is provided on the upper side of the support base 2, a fixing block 202 is provided on the upper surface of the limiting groove 201, a pressure block 203 is threadedly connected to the upper side of the fixing block 202, a first cylinder 301 is provided inside the installation box 3, the output end of the first cylinder 301 is fixedly connected to a connecting rod 302, the other end of the connecting rod 302 is fixedly connected to a limiting block 303, and a card slot 304 is provided on the side of the limiting block 303 close to the support base 2. There are six groups of grooves 304, and a movable slot 401 is provided in the middle of the vertical plate 4. The vertical plate 4 is fixedly connected to the side of the support seat 2 with a sliding rod 402, and a mounting plate 403 is provided on the upper side of the vertical plate 4. The upper surface of the mounting plate 403 is fixedly connected to the second cylinder 404, and the output end of the second cylinder 404 is fixedly connected to the telescopic rod 405, and the other end of the telescopic rod 405 is fixedly connected to the connecting block 406. The side of the connecting block 406 close to the pressure block 203 is threadedly connected to the pressure block 407, and the lower surface of the pressure block 407 is provided with an imprint.

[0033] The materials of the fixing block 202 and the pressure block 203 are both nitrile rubber. The use of nitrile rubber makes the fixing block 202 and the pressure block 203 have a certain toughness and can withstand multiple side sealing operations.

[0034] The groove size and length of the card slot 304 are arranged in increasing order from bottom to top. According to the size of the packaging bag to be side-sealed and the different requirements of the side sealing position of different styles of products, the packaging bag is placed between grooves of different sizes and lengths. On the one hand, it can prevent the position displacement of the packaging bag and the side sealing angle deviation during the side sealing process of the outer packaging to a certain extent. On the other hand, it can also meet the different requirements of the side sealing position of different sizes of packaging bags and different styles of products.

[0035] The support seat 2 and the sliding rod 402 are each provided with two groups. The connecting rod 302 passes through the movable slot 401 and is arranged between the fixed block 202 and the sliding rod 402. The connecting rod 302 is set in the movable slot 401. When the first cylinder 301 drives the connecting rod 302 installed at its output end to move up and down, it drives the limit block 303 installed at the other end to move up and down. The limit block 303 is provided with grooves of different sizes. By adjusting the height of the limit block 303, it can be adapted to packaging products of different thicknesses.

[0036] The telescopic rod 405 passes through the mounting plate 403 and extends to the other side of the mounting plate 403 and is located directly above the pressure block 203. The other end of the telescopic rod 405 is fixedly connected to the connecting block 406 and the pressing block 407. The telescopic rod 405 drives the pressing block 407 to move downward. The packaging bag to be side-sealed is placed between the pressing block 407 and the pressure block 203. The side sealing operation of the product to be packaged is completed by mutual squeezing of the two blocks.

[0037] The pressure block 203 and the stamping block 407 are both inverted L-shaped. The stamping block 407 is equipped with multiple groups of prints with different styles. The stamping block 407 is equipped with multiple groups that can be connected to the connecting block 406 through threads. At the same time, the lower surface of the stamping block 407 is provided with multiple groups of prints with different styles, which can be adjusted and replaced at any time. The side-sealed packaging bags with different prints can reflect the uniqueness and difference of the packaged products, making the processed products more popular with consumers.

[0038] The implementation principle of the side sealing mechanism of a cream paper packaging machine in the embodiment of the present application is as follows: a connecting rod 302 is arranged in a movable groove 401.

The limit block 303 is provided with grooves of different sizes inside. By adjusting the height of the limit block 303 to adapt it to packaging products of different thicknesses, the packaging bag is placed between grooves of different sizes and lengths. On the one hand, it can prevent the position of the packaging bag from being offset and the side sealing angle deviation from occurring during the side sealing process of the outer packaging to a certain extent. On the other hand, it can also meet the different requirements of the side sealing position of different packaging bag sizes and different styles of products. At the same time, the printing block 407 is equipped with multiple groups that can be connected to the connecting block 406 by threads. The lower surface of the printing block 407 is provided with multiple groups of different styles of prints, which can be adjusted and replaced at any time. The side-sealed packaging bags with different prints can reflect the uniqueness and difference of the packaging products, making the processed products more popular with consumers.
