Select rows from table having specific values depending on another values in the same table

I need to be able to select all Userpin that have tr_type 7 only but if there is tr_type 7 and 8 in other row ignore 7 and 8 example:

Userpin  TrDate       Time1      Tr_type4555     12-02-2020    7:30         74555     12-02-2020    14:30        86985     12-02-2020    7:34         79854     12-02-2020    7:15         78542     12-02-2020    7:16         78542     12-02-2020    14:40        8

Using this data set I am looking for Query To Get that data with userpin that have only tr_type equal 7 in current day and i want the result like that :

Userpin  TrDate       Time1      Tr_type6985     12-02-2020    7:34         79854     12-02-2020    7:15         7

i used that query to get data in current day

select UserPIN ,TrDate,Time1,Tr_Typefrom mytablewhere UserPIN in (6985,9854,4555,8542,4062,7070,4189,4197)and TrDate=CAST(GETDATE() AS DATE)

This seems like a simple thing to query, but I am finding myself up against a wall. What's the best way to accomplish this in a reasonably efficient way?
