Description

Technical Field

[0001] The present application relates to the technical field of urine pad production, and in particular to a pressing device for producing pet urine pads. Background Art

[0002] Pet diapers are absorbent materials, mainly made of cotton pulp and polymer absorbents, which are used to absorb pet excrement. The water absorption rate can reach dozens of times its own volume. After absorbing water, it can expand into a jelly-like state, without leakage or stickiness. It contains advanced antibacterial agents, which can deodorize and eliminate odors for a long time.

[0003] In order to ensure good absorption effect, existing pet urine pads usually adopt a multi-layer structure, and a waterproof layer is also adhered to the bottom to ensure that pet urine will not leak. In order to ensure the tightness of the connection between the layers, it is usually necessary to heat press them. Depending on the size of the urine pad, the grid shape of the hot press is also different. The existing grid shape switching requires the use of an integral pressing roller, and the cost of the pressing roller with a hot pressing line is much higher than that of a smooth pressing roller, so this will greatly increase the production cost. In order to solve the above problems, the present application provides a pressing device for the production of pet urine pads.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

A hot pressing roller is arranged above the transmission roller, and the outer side of the hot pressing roller is covered with a hot pressing net that fits with its outer wall. The hot pressing net is a combination of several diamond structures with adjustable shapes. Fixed blocks are welded at both end points of the hot pressing net, and the fixed block and the hot pressing roller are detachably connected. The fixed block is electrically connected to an external power supply mechanism through a brush structure.

[0007] Preferably, the diagonal length of the rhombus structure of the hot pressing net is adjustable.

[0008] Preferably, the brush structure comprises a conductive ring electrically connected to the outside, and each of the fixed blocks is welded with an elastic rod, and the end of the elastic rod is bonded to the conductive sheet inside the conductive ring through a graphite block.

[0009] Preferably, a guide roller is arranged on the input side of the transmission roller, and the guide roller is arranged in contact with the bottom of the absorption layer.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0023] Embodiment 1:

[0024] A pressing device for producing pet urine pads, referring to Figure 1 - Figure 5 The urine pad includes a waterproof layer 3 and an absorption layer 4. The transmission roller 1 is used to transmit the urine pad. A driving structure is arranged on the outer side of the transmission roller 1. A hot pressing roller 2 is arranged above the transmission roller 1, and the outer side of the hot pressing roller 2 is covered with a hot pressing net 5 that fits the outer wall thereof. The hot pressing net 5 is a combination of several rhombus structures with adjustable shapes. Fixed blocks 6 are welded at both end points of the hot pressing net 5, and the fixed block 6 and the hot pressing roller 2 are detachably connected. Both sides of the fixed block 6 are insulating structures, and a conductive sheet that does not contact the fixing bolt is arranged on the inner side thereof. The conductive sheet connects the hot pressing net 5 and the elastic rod 13 to ensure the normal transmission of current. The fixed block 6 is electrically connected to the external power supply mechanism through a brush structure.

[0025] The diagonal length of the diamond structure of the hot pressing mesh 5 is adjustable. When the diamond area of ​​each diamond needs to be adjusted, the fixing block 6 is removed from the hot pressing roller 2. At this time, the fixing blocks 6 at both ends are pushed toward the middle position, which will increase the diameter of the hot pressing mesh 5. At this time, the hot pressing mesh 5 and the hot pressing roller 2 can be removed, and a hot pressing roller 2 with a larger or smaller diameter can be used. After the hot pressing mesh 5 is sleeved on the replaced hot pressing roller 2, the hot pressing mesh 5 is tightened to make it adhere to the outer wall of the hot pressing roller 2, and then the fixing block 6 is tightened to complete the replacement of the hot pressing roller 2 inside the hot pressing mesh 5. The above operations are all performed under power-off conditions. The effective range of the hot pressing mesh 5 on the hot pressing roller 2 will be shortened as the diameter increases, and the size of the processed urine pad needs to be controlled within a reasonable range.

[0026] Reference Figure 1 - Figure 5 The brush structure includes a conductive ring 12 electrically connected to the outside, and each fixed block 6 is welded with an elastic rod 13, and the end of the elastic rod 13 is fitted with the conductive sheet inside the conductive ring 12 through the graphite block 14. The elastic rod 13 has elasticity toward the outside to ensure that the graphite block 14 and the conductive sheet of the conductive ring 12 fit together, so that the current is conducted without affecting the rotation of the hot pressing roller 2. The two conductive rings 12 are respectively connected to the positive and negative electrodes of the external DC power supply. The hot pressing net 5 is made of an alloy with a large resistance value. When current passes through, heat is generated to achieve hot pressing.

[0027] Reference Figure 1 - Figure 2 A guide roller 7 is arranged on the input side of the driving roller 1. The guide roller 7 is arranged in contact with the bottom of the absorption layer 4. The guide roller 7 is used to guide the absorption layer 4 so that there is a certain distance between it and the waterproof layer 3 during the processing.

[0028] Reference Figure 1 - Figure 2A glue coating roller 8 is also provided on the input side of the driving roller 1, and the glue coating roller 8 is attached to the top of the waterproof layer 3, and a glue groove 9 is also provided above the glue coating roller 8, and the output port of the glue groove 9 and the outer wall gap of the glue coating roller 8 are matched, and the glue coating roller 8 rotates toward one side of the driving roller 1, and both ends of the glue coating roller 8 are provided with scrapers 10 that are attached to its end face, and the scraper 10 is inclined toward the outer angle away from the end of the glue coating roller 8, and a receiving box 11 for receiving excess glue is provided below the scraper 10. The outer wall of the glue coating roller 8 will be stuck with the glue output from the glue groove 9. During the rotation of the glue coating roller 8, the scraper 10 will scrape it off the outer wall of the glue coating roller 8, and the scraped glue will flow along the scraper 10 to the outside of the two ends of the glue coating roller 8, and finally be received by the receiving box 11, so as to avoid excessive glue causing it to adhere to the position without the absorption layer 4, affecting the normal use of the urine pad.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
