Description

Technical Field

[0001] This utility model relates to the field of thermoforming machine technology, specifically to a thermoforming machine with automatic material feeding capability. Background Technology

[0002] Thermoforming machines are commonly used equipment for manufacturing various plastic products. By placing the raw materials to be processed into a mold and then extruding the raw materials, the shaped items are obtained. Therefore, many product processing requires the use of thermoforming machines. For example, plastic cups, plastic plates, plastic boxes and other plastic packaging containers are usually made by thermoforming machines.

[0003] When using existing thermoforming machines, the raw materials to be processed are usually placed on the lower mold base of the thermoforming machine, and then pressed into shape by the upper mold base. During this process, the raw materials need to be placed on the thermoforming machine manually, which is inconvenient for quickly unloading the raw materials. At the same time, it is very easy for the operator to make mistakes and cause accidents. Utility Model Content

[0004] The purpose of this invention is to provide a thermoforming machine with automatic material feeding, so as to solve the problem mentioned in the background art that the thermoforming machines currently in use are inconvenient for users to quickly feed materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding thermoforming machine, comprising: an operating machine and a connecting rod, a control box installed on one side of the operating machine, a lower mold base installed on the top of the operating machine, a lower mold installed on the top of the lower mold base, an upper mold base installed on the top of the lower mold base, an upper mold installed on the bottom of the upper mold base, a connecting frame installed on the top of the upper mold base, a cylinder installed on the top of the connecting frame, and the connecting rod passing through the connecting frame and installed on the top of the operating machine.

[0006] Preferably, a fixed frame is installed on one side of the manipulator, and a drive motor is installed at the bottom of the fixed frame through the outer shell. The output end of the drive motor is connected to a transmission shaft through a connecting shaft.

[0007] Preferably, a gear is connected to the outer side of the drive shaft, a rack is meshed with the top of the gear, a movable rod is connected to the top of the rack, a telescopic rod is connected to the bottom of the movable rod, a movable spring is installed inside the telescopic rod, and a connecting plate is installed on one side of the movable rod.

[0008] Preferably, a telescopic plate is installed inside the connecting plate through a groove, a reset rod is installed on the side of the two sets of telescopic plates that are close to each other, a reset spring is installed between the two sets of reset rods and the groove of the connecting plate, and a fixing block is installed on one side of the telescopic plate.

[0009] Preferably, a push rod is connected through both sides of the lower mold base, a connecting rod is installed on one side of the push rod, and a slider is installed on the top of the connecting rod.

[0010] Preferably, a connecting block is sleeved on the outer side of the slider, and a movable block is installed on one side of the connecting block.

[0011] Preferably, a locking block is installed on one side of the movable block, and a telescopic spring is installed between the push rod and the groove of the lower mold base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this automatic feeding thermoforming machine, the raw material can be placed on the connecting plate. Then, through the cooperation of gears and racks, the movable rod pushes the connecting plate to move and push the connecting plate onto the lower mold base. During the movement of the connecting plate, the fixed blocks on both sides will not squeeze the telescopic plate. Then, the telescopic plate will retract to both sides through the cooperation of the return spring and the return rod. At this time, the raw material on the connecting plate will fall onto the lower mold base, thereby realizing the automatic feeding of the raw material and avoiding accidents. This is the characteristic of the automatic feeding thermoforming machine.

[0013] 1. This automatic feeding thermoforming machine, during processing, uses the gear and rack mechanism to move the movable plate onto the lower mold base. Then, the telescopic plate moves to both sides with the help of the return spring and return rod. At this time, the raw material on the connecting plate falls into the lower mold base, thus feeding the material to the user. There is no need to manually place the raw material on the thermoforming machine, avoiding the occurrence of accidents.

[0014] 2. This automatic feeding thermoforming machine can pull the pull rod during processing according to the usage requirements, so that the slider and connecting block cooperate to drive the moving block and the locking block to move to both sides. At this time, the lower mold can be quickly removed from the lower mold base, which is convenient for replacing the lower mold. Similarly, the upper mold can be replaced to meet the different usage needs of users. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution: an automatic feeding thermoforming machine, comprising: an operating machine 1 and a connecting rod 9, a control box 2 installed on one side of the operating machine 1, a lower mold base 3 installed on the top of the operating machine 1, a lower mold 4 installed on the top of the lower mold base 3, an upper mold base 5 installed on the top of the lower mold base 3, an upper mold 6 installed at the bottom of the upper mold base 5, a connecting frame 7 installed on the top of the upper mold base 5, a cylinder 8 installed on the top of the connecting frame 7, and the connecting rod 9 passing through the connecting frame 7 and installed on the top of the operating machine 1.

[0025] A fixed frame 10 is installed on one side of the operating machine 1. A drive motor 11 is installed at the bottom of the fixed frame 10 through the outer casing. The output end of the drive motor 11 is connected to a transmission shaft 12 through a connecting shaft. A gear 13 is connected to the outside of the transmission shaft 12. A rack 14 is meshed with the top of the gear 13. A movable rod 15 is connected to the top of the rack 14. A telescopic rod 16 is connected to the bottom of the movable rod 15. A movable spring 17 is installed inside the telescopic rod 16. A connecting plate 18 is installed on one side of the movable rod 15. A telescopic plate 19 is installed inside the connecting plate 18 through a groove. A reset rod 20 is installed on the side of the two sets of telescopic plates 19 that are close to each other. A reset spring 21 is installed between the two sets of reset rods 20 and the groove of the connecting plate 18. A fixing block 22 is installed on one side of the telescopic plate 19. The fixing block 22 is installed on one side of the fixed frame 10. Two sets of fixing blocks 22 are symmetrically installed on the fixed frame 10 about the center line of the connecting plate 18.

[0026] In practical implementation, when automatic feeding is required, the thermoforming machine uses a mechanical gripper to place the raw material on the connecting plate 18. Then, the drive motor 11 is started, which drives the gear 13 to rotate via the transmission shaft 12. The gear 13 meshes with the rack 14, and the rotation of the gear 13 drives the movable rod 15 to move via the rack 14. The movable rod 15 then drives the connecting plate 18 and pushes it to the top of the lower mold base 3. During the movement of the connecting plate 18, the fixing blocks 22 on both sides will... The connecting plate 18 squeezes the telescopic plate 19 in the groove, causing the two sets of telescopic plates 19 to move closer to each other. At this time, the raw material is on the telescopic plate 19 and will not fall down. When the connecting plate 18 moves to the top of the lower mold base 3, since the fixing block 22 is a sloping structure, the fixing block 22 will not squeeze the telescopic plate 19. Then the telescopic plate 19 will move to both sides through the cooperation of the return spring 21 on both sides and the return rod 20. Without the support of the telescopic plate 19 for the raw material, the raw material will fall into the lower mold 4 of the lower mold base 3.

[0027] At this time, gear 13 continues to rotate. Since gear 13 is missing some teeth, when the missing teeth part of gear 13 rotates to the top, gear 13 is no longer engaged with rack 14. At this time, the movable rod 15 will move in the opposite direction through the cooperation of the telescopic rod 16 at the bottom and the movable spring 17, and pull the connecting plate 18 to one side. During the movement of the connecting plate 18, the telescopic plate 19 will move. At the same time, it will be subjected to the inclined surface of the fixed block 22. During the movement, the telescopic plate 19 will be continuously squeezed by the fixed block 22, so that the two sets of telescopic plates 19 move closer to each other. When the connecting plate 18 moves completely out from the top of the lower mold base 3, the two sets of telescopic plates 19 will be completely close together, which makes it convenient to place the next set of raw materials, thus achieving the function of automatic material unloading.

[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 7 As can be seen, when in use, the raw materials can be placed on the connecting plate 18 according to the usage requirements, and then the raw materials can be pushed onto the lower mold base 3 by the movable rod 15. The automatic feeding function can be achieved by relying on the contraction of the telescopic plate 19.

[0029] Ejector rods 23 are connected through both sides of the lower mold base 3. A connecting rod 24 is installed on one side of the ejector rod 23. A slider 25 is installed on the top of the connecting rod 24. A connecting block 26 is sleeved on the outside of the slider 25. A movable block 27 is installed on one side of the connecting block 26. A locking block 28 is installed on one side of the movable block 27. A telescopic spring 29 is installed between the ejector rod 23 and the groove of the lower mold base 3. The locking block 28 is inserted into the lower mold 4 through a groove that matches the size of the locking block 28.

[0030] In practical implementation, this automatic feeding thermoforming machine can be used by pulling the push rod 23 to one side according to the usage requirements. Pulling the push rod 23 to one side will drive the connecting block 26 to one side through the connecting rod 24. The top of the connecting rod 24 is equipped with a slider 25, and the slider 25 is slidably connected to the connecting block 26 through the inclined slide groove. The slider 25 moves through the connecting rod 24. When the slider 25 moves, it will drive the connecting block 26 to move through the inclined slide groove. Affected by the inclined slide groove, the two sets of connecting blocks 26 will move away from each other. The movable block 27 will make the connecting blocks 26 move away from each other. At the same time, the locking block 28 will move out of the groove of the lower mold 4. Without the locking block 28 limiting and fixing the lower mold 4, the lower mold 4 can be quickly replaced.

[0031] When installing the lower mold 4, simply align the lower mold 4 with the groove of the lower mold base 3 and loosen the ejector rod 23. The ejector rod 23 will be reset by the telescopic spring 29, causing the connecting rod 24 to move in the opposite direction. Through the cooperation of the slider 25 and the inclined groove, the connecting block 26 and the movable block 27 move in the opposite direction. At this time, the locking block 28 can be locked in the lower mold 4, thereby fixing the lower mold 4 in the lower mold base 3, which makes it convenient for users to quickly change the mold.

[0032] See Figure 1 , Figure 4 , Figure 5 and Figure 6 It can be seen that the mold can be quickly changed according to the needs of use, so that products of different shapes can be processed.

[0033] In summary, this automatic feeding thermoforming machine allows raw materials to be placed into the lower mold 4 of the lower mold base 3 during use. Then, the control box 2 on one side of the operating machine 1 controls the cylinder 8 to push the connecting frame 7 to move. The moving connecting frame 7 will slide along the connecting rod 9, thus ensuring the stability of the connecting frame 7. At the same time, the cylinder 8 driving the connecting frame 7 will cause the upper mold base 5 to move the upper mold 6 towards the lower mold base 3, at which point the product can be pressed and formed. This is the characteristic of the automatic feeding thermoforming machine. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
