Description

Technical Field

[0001] This utility model relates to the field of bonding equipment technology, specifically a bonding machine for a pearl cotton production line. Background Technology

[0002] EPE foam is a new type of environmentally friendly packaging and filling material. It has better performance and lower cost than traditional materials. Due to its special advantages, it not only does not pollute the environment, but can also be repeatedly recycled. In the production process of EPE foam, it is usually necessary to bond it into packaging components, which requires the use of bonding machines.

[0003] For example, patent publication number CN217454978U discloses an adhesive bonding machine for a pearl cotton production line, including a main body of the device. The main body of the device includes a support plate, a control panel on one side of the front end of the support plate, a conveyor belt on the top surface of the support plate, pearl cotton on the top of the conveyor belt, a processing box on the top of the support plate, an observation window at the front end of the processing box, a connecting pipe on one side of the top inside the processing box, a pump body sleeved on the outside of the connecting pipe, an integrated plate at the bottom of the connecting pipe, a nozzle at the bottom of the integrated plate, a hydraulic push rod on the other side of the top inside the processing box, a pressure plate at the bottom of the hydraulic push rod, and a mixing box on the top of the processing box. The mixing box has a mixing structure inside that allows the device to heat and stir the adhesive to prevent it from solidifying. Through the mixing structure, the device can stir the adhesive during use, preventing the adhesive from solidifying after a long period of time, thus improving processing efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the aforementioned comparative document, when bonding EPE foam, adhesive is sprayed onto the upper part of the EPE foam through a nozzle, and a lower pressure plate applies pressure to the EPE foam to achieve bonding. However, in reality, when bonding two pieces of EPE foam, it is essential to align them to ensure the quality of the bonded product. The aforementioned comparative document describes a method where adhesive is sprayed onto one piece of EPE foam first, and then the other piece of EPE foam is placed on the adhesive-coated piece and pressure is applied for bonding. If manual alignment is incorrect, the position between the two pieces of EPE foam cannot be corrected, reducing the bonding efficiency. Therefore, there is an urgent need in the field to improve the bonding machine used in EPE foam production lines to overcome the shortcomings of the existing technology. Utility Model Content

[0030] In this specific implementation embodiment: When bonding two pieces of pearl cotton, the second piece to be bonded 30 and the first piece to be bonded 29 are overlapped and placed on the transmission belt 2, roughly aligned with the position of the positioning unit 4. The positioning unit 4 aligns the first piece to be bonded 29 and the second piece to be bonded 30. The main controller 31 activates the second telescopic device 13, and the telescopic end of the second telescopic device 13 drives the fixing block 14 to move down. The lower side of the first positioning plate 16 abuts against the upper part of the transmission belt 2. Then, the third telescopic device 15 is activated, and the telescopic end of the third telescopic device 15 drives the first positioning plate 16 to move. The two first positioning plates 16 align the opposite sides of the first piece to be bonded 29 and the second piece to be bonded 30. Then, the first drive is activated. Motor 21, the output end of the first drive motor 21 drives the first drive screw 20 to rotate. The threads of the first drive screw 20 located on the inner side of the first sliding groove 19 are symmetrical and opposite. When the first drive screw 20 rotates, it drives the two first sliding blocks 18 to move towards each other in the first sliding groove 19.

The second telescopic device 13 drives the third telescopic device 15 to move upward, opening the transmission belt 2. The transmission belt 2 drives the aligned first bonding component 29 and second bonding component 30 to move below the adsorption seat 6. The first telescopic device 5 is activated, causing the adsorption seat 6 to move downwards. The adsorption device 11 is activated, and the adsorption device 11, through the flexible air tube 12 and several suction cups below the adsorption seat 6, adsorbs the first bonding component 29. Adhesive is supplied in the glue tank 7 through the glue storage box 9 and the glue delivery tube 10. After adsorbing the first bonding component 29, the adsorption seat 6 moves upwards and is driven by the drive unit 8 to move into the frame 3. The second drive motor 22 is activated, and the output end of the second drive motor 22 drives the second drive screw 25 to rotate. When the second drive screw 25 rotates, it drives the second sliding block 23 to move in the second sliding groove 24. The second sliding block 23 carries... The movable adsorption seat 6 moves into the frame 3, and the telescopic end of the first telescopic device 5 moves down to apply the adhesive in the adhesive dip trough 7 to the lower side of the first part to be bonded 29. Then, the first part to be bonded 29 is moved again to above the second part to be bonded 30. The first telescopic device 5 drives the adsorption seat 6 to move down to bond the first part to be bonded 29 and the second part to be bonded 30. During this process, the first part to be bonded 29 and the second part to be bonded 30 can be placed again in another set of positioning units 4. When the first part to be bonded 29 and the second part to be bonded 30 are bonded, the transmission belt 2 drives in the direction of transmission, so that the two stations can bond pearl cotton at the same time. By positioning the two pearl cotton blocks before bonding, the efficiency and quality of bonding pearl cotton are improved.

[0031] Example 2

[0032] Please see Figure 6 This embodiment includes the above embodiment, and further includes: a plug block 26 is fixedly installed on the side of the first positioning plate 16, the telescopic end of the third telescopic device 15 is provided with a plug groove 27 adapted to the plug block 26, and a locking bolt 28 is threaded through the telescopic end of the third telescopic device 15, one end of which is threadedly connected to the side of the plug block 26.

[0033] In this embodiment, when the first positioning plate 16 and the second positioning plate 17 are not compatible with the shapes of the first part to be bonded 29 and the second part to be bonded 30, for example, when the first part to be bonded 29 and the second part to be bonded 30 are circular, the first positioning plate 16 can be replaced with a shape that is compatible with the first part to be bonded 29 and the second part to be bonded 30. The insertion block 26 on the first positioning plate 16 with the compatible shape is inserted into the insertion groove 27, and one end of the locking bolt 28 is threaded through the end side of the third telescopic device 15 and connected to the side of the insertion block 26. This facilitates the installation or later replacement of the first positioning plate 16 and improves the applicability of the bonding device.

[0034] Example 3

[0035] Please see Figure 1 and Figure 2 This embodiment includes all the above embodiments, and further includes: a support plate is fixedly connected between the two conveyor support frames 1, the upper side of the support plate abuts against the inner top wall of the transmission belt 2, and the adsorption seat 6 is smaller than the glue dipping groove 7 and its width is not less than the width of the transmission belt 2.

[0036] In this embodiment, the support plate is located between two conveyor support frames 1. It is not shown in the figure because it is blocked by the transmission belt 2. The support plate is adapted to the position of the adsorption seat 6. It is mainly used to support the transmission belt 2 and prevent the elasticity of the transmission belt 2 from reducing the contact force between the first part to be bonded 29 and the second part to be bonded 30. The adsorption seat 6 is smaller than the glue tank 7 and its width is not less than the width of the transmission belt 2, ensuring that it can adsorb the pearl cotton block. As long as the pearl cotton block can be placed on the transmission belt 2, the adsorption seat 6 can adsorb the pearl cotton through the suction cup at its lower part, thereby improving the applicability of the bonding device.
