Description

Technical Field

[0001] This utility model belongs to the field of refrigerator packaging technology, specifically relating to a special refrigerator high-position bagging machine. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product used to keep food or other items at a constant low temperature. The world's first compression-type household refrigerator was invented in the United States in 1910. In 1925, the Swedish company Lido developed a household absorption refrigerator. In 1927, General Electric in the United States developed a fully enclosed refrigerator. In 1930, air-cooled continuous diffusion absorption refrigerators using different heating methods were launched on the market. In 1931, the new refrigerant Freon was successfully developed. Household refrigerator production began in the latter half of the 1950s, and China began producing refrigerators in the 1950s.

[0003] After the special refrigerators are manufactured, they need to be bagged to prevent the surface of the refrigerator from being scratched by sharp objects during transportation. The current method is generally to bag them manually, which is not only labor-intensive but also inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a special refrigerator high-position bagging machine with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A special refrigerator high-position bagging machine includes a frame. A feeding mechanism for feeding PE film is provided on one side of the frame. A refrigerator transport device for transporting special refrigerators is provided at the bottom of the side of the frame away from the feeding mechanism. An adjusting frame is installed on the frame above the refrigerator transport device. A high-position bagging device is slidably connected to the adjusting frame. A driving device for moving the high-position bagging device is also installed on the adjusting frame. A cold-cutting and heat-sealing mechanism for cutting and heat-sealing the packaging film is installed on the frame at the top of the adjusting frame.

[0007] As a further optimization of this utility model, the feeding mechanism includes PE film B and PE film A rotatably connected to the frame. A motor-driven roller is installed below both PE film B and PE film A. An opening cylinder B and an opening cylinder A are respectively installed on the side of PE film B and PE film A near the refrigerator transport device. A length measuring device is installed below both opening cylinder B and opening cylinder A.

[0008] As a further optimization of this utility model, a buffer structure is provided on the frame of the length measuring device on the side away from the PE film B and PE film A. The buffer structure includes a buffer roller A corresponding to the PE film B, and a buffer roller B corresponding to the PE film A.

[0009] As a further optimization of this utility model, the refrigerator transport device includes a roller conveyor line disposed below the frame. The roller conveyor line is provided with a block A and a block B on both sides of the high-position bagging device. Two symmetrically arranged central mechanisms are movably connected on the roller conveyor line between the block A and the block B.

[0010] As a further optimization of this utility model, the cold cutting and heat sealing mechanism includes cylinder A and cylinder B mounted on the frame. Cylinder A and cylinder B are symmetrically arranged. A drive wheel is rotatably connected to the frame below cylinder A and cylinder B. Cylinder D and cylinder C are respectively mounted on both sides of the drive wheel. Cylinder E and cylinder F are symmetrically mounted on the frame below the drive wheel. A cold cutting knife is mounted on the output end of cylinder E, and a heat sealing knife is mounted on the output end of cylinder F. Cylinder G and cylinder H are also symmetrically mounted on the frame below cylinder F.

[0011] As a further optimization of this utility model, the high-position bagging device includes a movable seat slidably connected to the adjusting frame. A gripper A and a gripper B are movably connected to the movable seat. A lead screw A that drives the gripper A to move and a lead screw B that drives the gripper B to move are installed on the movable seat. A motor B is also installed on the side of the movable seat near the adjusting frame. A set of cylinders for coordinating clamping actions is installed on both gripper A and gripper B. The cylinder set includes cylinder J, cylinder K, cylinder M and cylinder L.

[0012] As a further optimization of this utility model, the driving device includes a synchronous belt rotatably connected to the inner cavity of the adjusting frame via two synchronous pulleys, the movable seat is fixed to the outer wall of the synchronous belt on the side near the synchronous belt, and a motor A for driving the synchronous belt to rotate is installed on the bottom wall of the inner cavity of the adjusting frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This application uses a feeding mechanism to automatically position and feed PE film, and a refrigerator transport device to automatically position and feed the product. In conjunction with a high-position bagging device, the expanded PE film tube is placed on the outer surface of the product. Finally, cylinders E and F drive the cold cutting knife and heat sealing knife to move in opposite directions to cut and heat seal the top of the PE film, thus completing the automatic bagging of the product without manual bagging, which greatly improves the packaging efficiency of the product.

[0015] 2. The feeding mechanism for feeding PE film includes PE film B and PE film A rotatably connected to the frame. PE film B and PE film A can be used alternately. When the PE film is used up, there is no need to stop the machine to replace the PE film, avoiding the problem of having to stop the machine immediately to replace the PE film after it is used up, which affects production efficiency.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1 - Figure 5As shown, a special refrigerator high-position bagging machine includes a frame 5 for support and connection. A feeding mechanism 1 for feeding PE film is provided on one side of the frame 5. The feeding mechanism 1 includes PE film B101 and PE film A102 rotatably connected to the frame 5. PE film B101 and PE film A102 can be used alternately to avoid the problem of having to stop the machine immediately to replace the PE film when it is used up, which would affect the production efficiency.

[0025] Both PE film B101 and PE film A102 are equipped with motorized rollers 108. On the side of PE film B101 and PE film A102 closest to the refrigerator transport device 2, respectively, opening cylinders B103 and A104 are respectively installed. Length measuring devices 105 are installed below both opening cylinders B103 and A104. When the motorized rollers 108 rotate, they can drive PE film B101 and PE film A102 to rotate through friction, thereby unwinding the PE film. Opening cylinders B103 and A104 are used to open holes in the unwound PE film B101 and PE film A102, respectively. Length measuring devices 105 are used to detect the unwound length of PE film B101 and PE film A102.

[0026] A buffer structure is provided on the frame 5 of the length measuring device 105 on the side away from PE film B101 and PE film A102. The buffer structure includes a buffer roller A106 corresponding to PE film B101 and a buffer roller B107 corresponding to PE film A102. The buffer rollers A106 and B107 are used to buffer and tension the PE film B101 and PE film A102 stretched after unwinding, so as to facilitate the subsequent processing of PE film B101 and PE film A102.

[0027] A refrigerator transport device 2 for transporting special refrigerators is provided on the bottom side of the frame 5 away from the feeding mechanism 1. The refrigerator transport device 2 includes a roller conveyor line 201 on the bottom side of the frame 5 away from the feeding mechanism 1. The roller conveyor line 201 is located on both sides of the high-position bagging device 4, with a barrier A202 and a barrier B203 respectively. When the product enters the roller conveyor line 201 and moves to the position of the barrier A202, if the barrier B203 detects that there is a product, the barrier A202 rises to block the product. If the barrier B203 detects that there is no product, the barrier A202 falls, and the product continues to be transported along the roller conveyor line 201 to the position of the roller barrier B203, thereby realizing the separation of products.

[0028] Two symmetrically arranged centering mechanisms 204 are movably connected on the roller conveyor line 201 between the barriers A202 and B203. When the product is conveyed to the barrier B203, the photoelectric device on the barrier B203 detects the product, and the barrier B203 rises to block the product. At the same time, the centering mechanisms 204 move from both sides towards each other, pushing the product to the middle position of the roller conveyor line 201, thereby achieving precise positioning of the product.

[0029] An adjusting frame 401 is installed on the frame 5 above the refrigerator transport device 2. A cold-cutting and heat-sealing mechanism 3 is installed above the adjusting frame 401. The cold-cutting and heat-sealing mechanism 3 includes cylinders A301 and B302 installed on the frame 5. Cylinders A301 and B302 are symmetrically arranged. A drive wheel 309 is rotatably connected to the frame 5 below cylinders A301 and B302. Cylinders D303 and C304 are respectively installed on both sides of the drive wheel 309. Cylinders E305 and F306 are symmetrically installed on the frame 5 below the drive wheel 309. A cold-cutting blade 310 is installed on the output end of cylinder E305, and a heat-sealing blade 311 is installed on the output end of cylinder F306. The frame below cylinder F306... Cylinders G307 and H308 are symmetrically installed on the 5. After the end of the PE film A102 passes over the buffer roller B107, it is pulled to the bottom of the cold cutting knife 310 and the heat sealing knife 311. When the PE film A102 is used, cylinder A301 is in the closed state, cylinder B302 is in the open state, cylinder C304 is in the open state, and cylinder D303 is in the closed state. When the PE film B101 is used, cylinder A301 is in the open state, cylinder B302 is in the closed state, cylinder C304 is in the closed state, and cylinder D303 is in the open state. The cold cutting knife 310 and the heat sealing knife 311 are used to cut and heat seal the PE film, respectively, so that the PE film tube forms a bag-shaped structure with a set length and the opening located at the bottom.

[0030] A high-position bagging device 4 is slidably connected to the adjusting frame 401. The high-position bagging device 4 includes a movable seat 404 slidably connected to the adjusting frame 401. A gripper A408 and a gripper B409 are movably connected to the movable seat 404. A lead screw A405 for moving gripper A408 and a lead screw B406 for moving gripper B409 are installed on the movable seat 404. A motor B407 is also installed on the side of the movable seat 404 closest to the adjusting frame 401. Both 408 and gripper B409 are equipped with a set of cylinders for coordinating clamping actions. The cylinder set includes cylinders J410, K411, M412 and L413. The inner cavity of the adjusting frame 401 is connected to the synchronous belt 402 through two synchronous pulleys. The movable seat 404 is fixed to the outer wall of the synchronous belt 402 on the side near the synchronous belt 402. The bottom wall of the inner cavity of the adjusting frame 401 is equipped with a motor A403 that drives the synchronous belt 402 to rotate.

[0031] When the PE film moves between grippers A408 and B409, firstly, motor A403 drives synchronous belt 402 to rotate, causing movable seat 404 to rise to the designated position. Then, through the rotation of lead screw B406, grippers B409 are moved to the appropriate position. Next, through lead screw A405, movable seat 404 is moved forward to the designated position, cooperating with cylinders J410, K411, M412, and L413 to clamp the four corners of the PE film. Then, motor A403 rotates in the opposite direction, causing movable seat 404 to move down, and the bag-shaped PE film with the opening at the bottom is placed on the product, thus realizing automatic bagging of the product.

[0032] It should be noted that, in use, this special refrigerator high-position bagging machine first places the PE film in the designated position on the frame 5, then pulls the outer end of the PE film A102 to the designated location along the line, and starts the motor-driven roller 108 to rotate, feeding the PE film. When the length measuring device 105 detects that the PE film has reached the set length, the perforating cylinder B103 starts to punch holes in the PE film. At the same time, the roller conveyor 201 is started to work with the blocking A202, blocking B203 and the centering mechanism 204 to automatically position and feed the product. When the product moves to below the movable seat 404, the motor A403 drives the synchronous belt 402 to rotate, driving the movable seat 404 to rise to the designated position. Simultaneously, the screw B406 rotates, moving the gripper B409 to the appropriate position. Then, the screw A405 moves the movable seat 404 forward to the designated position. This, in conjunction with cylinders J410, K411, M412, and L413, clamps the four corners of the PE film. Then, the motor A403 rotates in the opposite direction, causing the movable seat 404 to move downward, placing the bag-shaped PE film with the bottom opening onto the product. Cylinders E305 and F306 drive the cold cutting blade 310 and heat sealing blade 311 to move towards each other, cutting and heat-sealing the top of the PE film. This completes the automatic bagging of the product, eliminating the need for manual bagging and greatly improving the packaging efficiency.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
